WHEREAS, Plaintiffs, the United States of America (United States), on behalf of the United States Environmental Protection Agency (EPA), and the Florida Department of Environmental Protection (FDEP), which is the agency of the State of Florida to which the Florida Legislature has delegated the exclusive power and duty to enforce Chapter 403, Florida Statutes, including the authority to bring actions in courts of competent jurisdiction for violations of the Florida Resource Recovery and Management Act pursuant to §§ 403.121, 403.131, 403.161, 403.708, and 403.727(2), Florida Statutes (together the Plaintiffs), have filed a complaint alleging that Defendant Mosaic Fertilizer, LLC (Mosaic) has violated the Resource Conservation and Recovery Act (RCRA), 42 United States Code (U.S.C.) § 6901etseq., and the Florida Resource Recovery and Management Act, § 403.702etseq., Florida Statutes (F.S.), and the applicable regulations in 40 C.F.R. Parts260-270, and in Chapter62-730, Florida Administrative Code (F.A.C.) at its sulfuric acid, phosphoric acid and fertilizer manufacturing facilities located in Florida (Facilities);

WHEREAS, the Complaint includes allegations that Mosaic failed to characterize and illegally treated, stored and disposed of hazardous wastes from various processes at its Facilities, including: the production of sulfuric acid, diammonium phosphate (DAP) and monoammonium phosphate (MAP) fertilizer, and fluorosilicic acid (FSA); wastes generated during cleaning of the phosphoric acid plant and fertilizer plant equipment; and wastewaters generated from the scrubbers used to control air pollution from the phosphoric acid plants and from other chemical and waste management processes at its Facilities without a RCRA permit or interim status. The Complaint also alleges that Mosaic illegally placed hazardous wastes in a Phosphogypsum Stack System dedicated for managing phosphoric acid production wastes

– 3 –

exempt from hazardous waste regulation pursuant to the Bevill Exemption, 40 C.F.R. § 261.4(b)(7), thus violating Sections 3004 and 3005 of RCRA, 42 U.S.C. §§ 6924-25, and the applicable regulations in 40 C.F.R.

2.        Pursuant to Section 3008(a)(2) of RCRA, 42 U.S.C. § 6928(a)(2), notice of the commencement of this action has been given to FDEP.

3.        For purposes of this Consent Decree only, Mosaic agrees that the Complaint states claims upon which relief may be granted pursuant to Sections 3004 and 3005 of RCRA, 42 U.S.C. §§ 6924 and 6925, and Sections 403.721, 403.722, and 403.727, F.S.

II.  APPLICABILITY

4.        The obligations of this Consent Decree apply to and are binding upon the United States, FDEP, Mosaic, and, as provided herein, The Mosaic Company, and any successors, assigns, or other entities or persons otherwise bound by law. Rights granted to EPA under this Consent Decree may be exercised by FDEP upon the written agreement of EPA and FDEP with notice to Mosaic. Nothing in this Consent Decree shall apply to administrative or enforcement proceedings other than this action or an action to enforce this Consent Decree. Nor does anything in this Consent Decree relieve Mosaic of its obligation to comply with any federal and state laws applicable to activities that are not within the definition of Work in this Consent Decree.

5.        No transfer of ownership or operation of all or a portion of a Facility, whether in compliance with the procedures of this Paragraph or otherwise, shall relieve Mosaic of its obligation to ensure that the terms of this Consent Decree are implemented, unless: (1) the transferee agrees in writing to undertake the obligations required by this Consent Decree and to be substituted for Mosaic as a Party to the Consent Decree and thus be bound by the terms thereof; and (2) the United States, after consultation with FDEP, consents in writing to relieve Mosaic and the Mosaic Company of their respective obligations under this Consent Decree pursuant to Section XVIII of this Consent Decree (Modification). At least thirty (30) Days prior

– 6 –

to a proposed transfer of Mosaic’s obligations under this Consent Decree, or such other period agreed to by the Parties in writing: (i) Mosaic shall provide a copy of this Consent Decree to the proposed transferee, if not previously provided; and (ii) shall provide written notice of the prospective transfer, together with a copy of the proposed written agreement (subject to Paragraphs 88 and 89 of this Consent Decree and as may otherwise be agreed in writing) transferring obligations to the transferee, to EPA, FDEP, the United States Attorney for the Middle District of Florida, and the United States Department of Justice, in accordance with Section XV (Notices) of this Consent Decree, together with a request for approval. The United States’ decision whether to approve the transferee’s substitution for Mosaic under this Consent Decree, and what conditions may attend approval, will take into account: (i) the status of the projects in Appendix 6 (RCRA Compliance Schedule), (ii) whether the transferee has or will have prior to the transfer the financial and technical capability to comply with this Consent Decree, (iii) and other factors that may be deemed relevant, including but not limited to the environmental compliance history of the proposed transferee and environmental management capabilities of the proposed transferee. As set forth in Appendix 2, Paragraph 36, any such transfer will not include the Financial Assurance obligations specified for Mosaic therein, and therefore will include Financial Assurance conditions appropriate to the transferee. Any transfer of ownership or operation of all or a portion of the Facility without complying with this Paragraph constitutes a violation of this Consent Decree. The United States’ refusal to approve, or approval with conditions for, the substitution of the transferee for Mosaic under this Consent Decree shall be subject to dispute resolution pursuant to Section XI (Dispute Resolution) of this Consent Decree, but any judicial review shall be conducted pursuant to Paragraph 70(a) of this

– 7 –

Consent Decree. If Mosaic does not prevail in such judicial review, Mosaic shall pay all costs incurred by the United States in connection with such judicial review, including attorney’s fees.

EPA reserves the right to require, upon written request, that a Correction Plan be submitted to EPA for approval in accordance with Paragraphs27-30, above. Mosaic’s compliance with this Paragraph is without prejudice to its rights under Section X (Force Majeure) and Section XI (Dispute Resolution) of this Consent Decree.

33.      Permits.   Where any compliance obligation under this Section requires Mosaic to obtain a federal, state, or local permit or other form of approval, Mosaic shall submit timely and complete applications and take such actions as are necessary to obtain all such permits or approvals. A request for supplementation by the permitting agency does not constitute a notice or finding that an application was incomplete for the purpose of this Paragraph unless the permitting agency determines that the original application was so deficient as to constitute a material breach of Mosaic’s obligations under this Consent Decree. Mosaic may seek relief

– 39 –

under the provisions of Section X of this Consent Decree (Force Majeure) for any delay in the performance of any such obligation resulting from a failure to obtain, or a delay in obtaining, any permit or approval required to fulfill such obligation, if Mosaic has submitted timely and complete applications and has taken such actions as are necessary to timely obtain all such permits or approvals.

34.     Provided that Mosaic remains in compliance with Section V (Compliance Requirements) or the Continuing Compliance Criteria set forth in Paragraph 32 at a Facility, that Facility shall not be required to operate as a Treatment Storage and Disposal Facility pursuant to Section 3005 of RCRA and its implementing federal and/or state regulations, with respect to:

  (a) the treatment, storage, transport, management, and disposal ofBevill-Exempt Wastes that have been commingled with hazardous wastes or otherwise managed in violation of law as alleged in the Complaint:

(i) prior to the lodging of this Consent Decree,

(ii) prior to completing the compliance projects set forth in Appendix 6 (RCRA Project Narrative and Compliance Schedule) as provided by Paragraph 13, or

(iii) during timely implementation of a Correction Plan as set forth in Paragraph 32;

(b) wastes that Paragraphs 15 through 18(a) allow to be input to Upstream Operations or Downstream Operations or managed in Recovery Units or together withBevill-Exempt Wastes; and

(c) wastes that Paragraph 18(b) allows to be transferred among Mosaic’s Florida Facilities.

VI. WORK TAKEOVER

35.      In the event EPA determines that Mosaic has: (a) ceased implementation of any portion of the Work; or (b) is seriously or repeatedly deficient or late in its performance of the Work; or (c) is implementing the Work in a manner that may cause an endangerment to human health or the environment, EPA, after consultation with FDEP and with the joint approval of the EPA Region 4 Regional Administrator and the Assistant Administrator for the EPA Office of Enforcement and Compliance Assurance, may issue a written notice (Work Takeover Notice) to Mosaic. Any Work Takeover Notice issued by EPA shall specify the grounds upon which such notice was issued and shall provide Mosaic a period of thirty (30) Days within which to remedy the circumstances giving rise to EPA’s issuance of such notice.

36.      If, after expiration of the thirty (30) Day period specified in Paragraph 35 of this Section, the Work Takeover Notice has not been withdrawn by EPA and Mosaic has not remedied to EPA’s satisfaction the circumstances giving rise to EPA’s issuance of the Work Takeover Notice, EPA at any time thereafter may undertake Work Takeover by: (a) assuming and/or directing the performance of; (b) seeking the appointment of a receiver to direct the performance of; or (c) only with the concurrence of FDEP, accessing Financial Assurance to finance the performance of all or any portions of the Work that EPA deems necessary to correct the violations or conditions that triggered the Work Takeover Notice pursuant to Paragraph 35 (Work Takeover). EPA shall notify Mosaic in writing (which writing may be electronic) if EPA determines that implementation of a Work Takeover is warranted under this Section of the Consent Decree. In the event that EPA seeks to appoint a receiver to direct the performance of the Work, Mosaic shall not oppose such appointment on grounds other than lack of competence or conflict of interest, but shall retain its right to challenge the underlying Work Takeover in

– 41 –

Dispute Resolution, as set forth in the following Paragraph and Section XI (Dispute Resolution) of this Consent Decree. In implementing any Work Takeover, EPA shall make reasonable efforts not to interfere with Facility operations not directly affected by the conditions that triggered the Work Takeover.

37.      In the event that Mosaic invokes Section XI (Dispute Resolution) of the Consent Decree with respect to EPA’s Work Takeover and/or its selection of options set forth in Paragraph 36 (which must be disputed together with the underlying Work Takeover and pursuant to Paragraph 70(a) of this Consent Decree), EPA during the pendency of any such dispute may, in its unreviewable discretion, commence and continue a Work Takeover until the earlier of: (a) the date that Mosaic remedies, to EPA’s satisfaction, the circumstances giving rise to issuance of the Work Takeover Notice; or (b) the date that a final decision is rendered in accordance with Section XI (Dispute Resolution) of the Consent Decree requiring EPA to terminate such Work Takeover.

38.      After commencement and for the duration of any Work Takeover, EPA or any appointed receiver shall have immediate access to and benefit of any Financial Assurance provided pursuant to Paragraph 25 and Appendix 2 (Financial Assurance) of this Consent Decree to implement the Work. If EPA or any appointed receiver are unable to access to the Financial Assurance, or the Work addressed by the Work Takeover is not covered by Financial Assurance, then any unreimbursed costs incurred by EPA in connection with the Work Takeover shall be considered a financial obligation owed by Mosaic to the United States and collectible in an action to enforce this Consent Decree. Nothing in this Paragraph shall be construed to relieve Mosaic of its obligation to provide adequate Financial Assurance pursuant to Appendix 2. In the event that it is determined in Dispute Resolution that the Work Takeover was not warranted, any

– 42 –

unexpended funds in aStand-by Trust that originated from a letter of credit, surety bond or corporate guarantee shall be used to restore anypre-existing Trust Fund to thepre-Work Takeover level, if necessary, and any balance of unexpended funds shall be released and used tore-establish the original financial mechanism(s).

VII.      SUPPLEMENTAL ENVIRONMENTAL PROJECT

39.      FDEP and Mosaic have agreed on a Supplemental Environmental Project (“SEP”) as described herein in Appendix 9. Mosaic, under the oversight of FDEP, shall remediate seepage breakout at the Mulberry Facility South Cooling Pond as further described in Appendix 9, and subject to the following conditions:

(a)        The cost of the SEP shall be based on direct expenditures for engineering services, materials, and for other third-party contractors or vendors, where needed to perform the SEP (the “Applicable SEP Costs”). Mosaic shall complete the SEP work described herein in Appendix 9, to the extent the Applicable SEP Costs do not exceed $1.2 Million.

(b)        Remediation shall continue to be performed by Mosaic until performance in full has been completed as described in Appendix 9.

(c)        If Mosaic determines that the costs of the SEP will or are likely to exceed $1.2 million in Applicable SEP Costs as a result of an “Unanticipated Event” or “Differing Site Condition,” Mosaic shall immediately so inform FDEP and suspend work and, to the extent feasible, do so prior to incurring Applicable SEP Costs in excess of $1.2 million. For the purposes of this paragraph, “Unanticipated Event” or “Differing Site Condition,” shall mean concealed or latent physical conditions or subsurface conditions at a portion of the site corresponding to the SEP work that (i) materially differ from the conditions described in Appendix 9 or (ii) are of an unusual nature, differing materially from the conditions ordinarily

– 43 –

encountered and generally recognized as inherent in the applicable SEP work. Following notice that performance of the SEP will exceed the above threshold, FDEP may either: (i) require a modification to the SEP to allow the Applicable SEP Costs to not exceed $1.2 million, or (ii) reach an agreement with Mosaic on any additional funds and the source of such funds that may be used to fund all or some portion of the Applicable SEP Costs in excess of $1.2 million.

(d)    If Mosaic fails to timely submit the notification of completion, or otherwise fails to complete the SEP within the timeframes provided in Paragraph 39(b), or if upon review of the certification of construction completion, FDEP determines that the project cannot be accepted due to a substantially incomplete certification of completion or due to substantial deviations from the approved SEP, Mosaic will be notified, in writing, of the reason(s) that prevent the acceptance of the project. Mosaic shall address all of the matters identified by FDEP that are inconsistent with the SEP described in Appendix 9, or the timeframes herein required, and submit a new certification of completion within 45 Days of receipt of FDEP’s notice, unless such FDEP notice specifies a greater period of time for submittal of a new certification of completion. If Mosaic, despite its best efforts to do so, fails to complete the SEP or if upon review of the new submittal, FDEP determines that the SEP is still incomplete or not in accordance with the SEP described in Appendix 9, Mosaic shall pay a stipulated penalty to FDEP equal to the greater of: (i) $1.2 Million (less the costs that Mosaic incurred on the SEP up to a maximum of $1.2 Million), or (ii) $25,000.

– 44 –

VIII. REPORTING REQUIREMENTS

40.      If Mosaic determines that it has violated or will violate, any requirement of this Consent Decree, Mosaic shall (unless otherwise directed by EPA or FDEP) notify EPA and FDEP of such violation and its likely duration, in writing, within twelve (12) Days of the date Mosaic first becomes aware of the violation, with an explanation of the likely cause of the violation and of the remedial steps taken, or to be taken, to prevent or minimize such violation. If the cause of a violation cannot be fully explained at the time the report is due, Mosaic shall so state in the report. Mosaic shall investigate the cause of the violation and shall then submit an amendment to the report, including a full explanation of any identifiable cause(s) of the violation, within thirty (30) Days of the date Mosaic becomes aware of the violation. Nothing in this Paragraph or Paragraphs 41 and 42 relieves Mosaic of its obligation to provide the notice required by Section X of this Consent Decree (Force Majeure).

41.      Periodic Reporting

(a)        Within forty-five (45) Days after the end of eachcalendar-quarter after lodging of this Consent Decree (quarters shall be calculated based on Mosaic’s December 31^st end-of-fiscal-year), until the quarter ending after the completion of the final compliance project identified in Appendix 6, Mosaic shall submit to EPA and FDEP a report for each Operating Facility for the preceding calendar quarter, that shall include (a) the status of any construction or compliance measures described in Appendix 6 and the applicable Facility Report for each Operating Facility; (b) completion of milestones set forth in Appendix 6; (c) problems encountered or anticipated, together with implemented or proposed solutions, with projects described in Appendix 6 and in the applicable Facility Report for each Operating Facility; (d) status of permit applications for projects described in Appendix 6; (e) status of plans for closure

(b)        Thereafter, and for a period of two (2) years, Mosaic shall submit such reports to Plaintiffs for each Operating Facility on a semi-annual basis. Thereafter Mosaic shall submit such reports annually until such time as Mosaic submits the Closure Application for an Operating Facility pursuant to Appendix 1 Attachment D (Closure of Phosphogypsum Stacks/ Stack Systems). Mosaic shall submit its next report within one-hundred-eighty (180) Days after the submission of the Closure Application, and annually thereafter until this Consent Decree is terminated with respect to that Operating Facility.

(c)      Following completion of the compliance projects “Big Holding Tank and Wash Solution System in Phosphoric Acid Plant” and “Granulation Wash Reconfiguration,” in Appendix 6 (RCRA Project Narrative & Compliance Schedule), Mosaic shall submit to EPA and

– 46 –

FDEP a report for each Operating Facility within forty-five (45) Days after the end of each calendar quarter identifying any transfer(s) of GHT Effluent to the BHT during the reporting period, including the following information: (a) the date of any transfer(s); (b) the reason for the transfer; (c) the volume of the contents in the GHT when Mosaic started and ceased use of the transfer line; (d) the volume transferred; and (e) a proposal for minimizing, if possible, any reoccurrence of the non-routine event that led to the transfer. These reports shall be submitted quarterly for a period of three (3) years following project completion. Thereafter, Mosaic shall submit such reports annually until such time as Mosaic submits the Closure Application for a Facility pursuant to Appendix 1 Attachment D (Closure of Phosphogypsum Stacks/Stack Systems).

(d)        Within forty-five (45) Days after the end of each calendar year after lodging of this Consent Decree, Mosaic shall submit reports for each Closing Facility that shall include: (a) status of plans for closure and long-term care; and (b) identification of any confirmed “critical condition,” as defined and reported to FDEP and/or EPA pursuant to Appendix 1.

42.      Whenever any violation of this Consent Decree, or any other event affecting Mosaic’s performance under this Consent Decree or the performance of its Facility may pose an immediate threat to the public health or welfare or the environment, Mosaic shall, unless otherwise directed, notify EPA and FDEP in Section XV (Notices), orally or by electronic or facsimile transmission as soon as possible, but no later than twenty-four (24) hours after Mosaic first knew of the event, and shall comply with the requirements of Appendix 1, Attachment E (Critical Conditions and Temporary Measures). Any violation of this notice requirement shall be deemed to terminate on the Day that both Plaintiffs have received actual notice of the violation

– 47 –

or event from Mosaic or by other means. This notice requirement does not relieve Mosaic of its obligation to comply with any federal and state laws applicable to the violation or event. This notice requirement is in addition to the requirement to provide notice of a violation of this Consent Decree set forth in the preceding Paragraph.

43.      All reports shall be submitted to the persons designated to receive Notices for Plaintiffs in Section XV (Notices) of this Consent Decree. All notices and submittals to “EPA and/or FDEP” under this Consent Decree (including Appendices), other than those required by this Section or that are submitted for approval pursuant to Paragraphs 27-29, may be submitted to FDEP only, provided that a copy of the cover letter identifying the notice or submittal is also sent to EPA. Mosaic also shall supply EPA with a copy of such notice(s) or submittal(s) upon request by EPA.

44.      Each report submitted by Mosaic under this Section shall be signed by a responsible corporate official of Mosaic (as defined in 40 C.F.R. § 270.11(a)) and shall include the following certification:

I certify under penalty of law that this document and all attachments were prepared under my direction or supervision in accordance with a system designed to assure that qualified personnel properly gather and evaluate the information submitted. Based on my inquiry of the person or persons who manage the system, or those persons directly responsible for gathering the information, the information submitted is, to the best of my knowledge and belief, true, accurate, and complete. I am aware that there are significant penalties for submitting false information, including the possibility of fine and imprisonment for knowing violations.

This certification requirement does not apply to emergency notifications where compliance would be impractical.

45.      The reporting requirements of this Consent Decree do not relieve Mosaic of any reporting obligations required by the RCRA Requirements or by any other federal, state, or local

– 48 –

law, regulation, permit, or other requirement. However, the reporting requirements of this Consent Decree shall not require Mosaic to re-submit any report, plan or information submitted by Mosaic to EPA and/or FDEP prior to the Effective Date of this Consent Decree.

46.      Any information provided pursuant to this Consent Decree may be used by the Plaintiffs in any proceeding to enforce the provisions of this Consent Decree and as otherwise permitted by law.

IX. STIPULATED PENALTIES

47.      Mosaic shall be liable for stipulated penalties to the United States and FDEP for violations of this Consent Decree as specified below, unless excused under Section X (Force Majeure). A violation includes failing to perform any obligation required by the terms of this Consent Decree, including any work plan or schedule approved under this Consent Decree, according to all applicable requirements of this Consent Decree and within the specified time schedules established by or approved under this Consent Decree.

48.      Civil Penalty.  If Mosaic fails to pay the civil penalty required to be paid under Section IV of this Consent Decree (Civil Penalty) when due, Mosaic shall pay a stipulated penalty of $1,000 per Day for each Day that the payment is late for the first ten (10) Days, together with Interest. Thereafter, Mosaic shall pay $3,000 per Day for each Day that the payment is late, with Interest. Late payment of the civil penalty shall be made in accordance with Section IV (Civil Penalty), Paragraph 10. Stipulated penalties for late payment of the civil penalty shall be paid in accordance with Paragraphs 64, 65, 67 and 68, below. All transmittal correspondence shall state that any such payment is for late payment of the civil penalty due under this Consent Decree, or for stipulated penalties for late payment, as applicable, and shall include the identifying information set forth in Paragraph 10, above.

– 49 –

49.      Compliance Requirements.  The following stipulated penalties shall accrue per violation per Day for each violation of the requirements identified in Section V (Compliance Requirements):

51.      Subject to the provisions of Paragraph 30, above, and except as otherwise specified in Paragraphs 54(b), stipulated penalties under this Section shall begin to accrue on the Day after performance is due or on the Day a violation occurs, whichever is applicable, and shall continue to accrue until performance is satisfactorily completed or until the violation ceases. Stipulated penalties shall accrue simultaneously for separate violations of this Consent Decree.

52.      Mosaic shall pay stipulated penalties to the United States and to FDEP within twelve (12) Days of a written demand by either Plaintiff, subject to its right to invoke dispute

– 50 –

resolution in accordance with Section XI (Dispute Resolution). Except as provided in Paragraph 39(d), Mosaic shall pay fifty percent (50%) of the total stipulated penalty amount due to the United States and fifty percent (50%) to FDEP. The Plaintiff making a demand for payment of a stipulated penalty shall simultaneously send a copy of the demand to the other Plaintiff.

53.      Each Plaintiff, may, in the unreviewable exercise of its discretion, reduce or waive stipulated penalties otherwise due to it under this Consent Decree. The determination by one Plaintiff not to seek stipulated penalties, or to subsequently waive or reduce the amount it seeks, shall not preclude the other Plaintiff from seeking the full amount of the stipulated penalties owed.

54.      Stipulated penalties shall continue to accrue as provided in Paragraph 51, during any Dispute Resolution, but need not be paid until the following:

a.        If the dispute is resolved by agreement or by a decision of the United States or FDEP that is not subject to judicial review or appealed to the Court, Mosaic shall pay accrued penalties determined to be owing, together with Interest, to the United States or FDEP within thirty (30) Days of the effective date of the agreement or the receipt of the United States’ or FDEP’s decision or order.

b.        If the dispute is appealed to the Court and the United States or FDEP prevails in whole or in part, Mosaic shall pay all accrued penalties determined by the Court to be owing, together with Interest, within sixty (60) Days of receiving the final Court decision.

55.      Mosaic shall pay stipulated penalties owing to the United States in the manner set forth and with the confirmation notices required by Paragraph 10, except that the transmittal letter shall state that the payment is for stipulated penalties and shall state for which violation(s) the penalties are being paid. Mosaic shall pay stipulated penalties owing to FDEP in accordance

with Paragraph 11, except that the transmittal letter shall state that the payment is for stipulated penalties and shall state for which violation(s) the penalties are being paid.

56.      Mosaic shall not deduct stipulated penalties paid under this Section in calculating its state and federal income tax.

57.      If Mosaic fails to pay stipulated penalties according to the terms of this Consent Decree, Mosaic shall be liable for Interest on such penalties, as provided for in 28 U.S.C. § 1961, accruing as of the date payment became due. Nothing in this Paragraph shall be construed to limit the United States or FDEP from seeking any remedy otherwise provided by law for Mosaic’s failure to pay any stipulated penalties.

58.      Subject to the provisions of Section XIII (Effect of Settlement/ Reservation of Rights) of this Consent Decree, the stipulated penalties provided for in this Consent Decree shall be in addition to any other rights, remedies, or sanctions available to the United States or FDEP for Mosaic’s violation of this Consent Decree or applicable law. Where a violation of this Consent Decree is also a violation of relevant statutory or regulatory requirements, Mosaic shall be allowed a credit for any stipulated penalties paid against any statutory penalties imposed for such violation.

X. FORCE MAJEURE

59.       Force majeure, for purposes of this Consent Decree, is defined as any event arising from causes beyond the control of Mosaic, of any entity controlled by Mosaic, or of Mosaic’s contractors, that delays or prevents the performance of any obligation under this Consent Decree despite Mosaic’s best efforts to fulfill the obligation. The requirement that Mosaic exercise best efforts to fulfill the obligation includes using best efforts to anticipate any potential force majeure and best efforts to address the effects of any potential force majeure

– 52 –

(1) as it is occurring and (2) following the potential force majeure such that the delay and any adverse effects of the delay are minimized to the greatest extent possible. Force majeure does not include Mosaic’s financial inability to perform any obligation under this Consent Decree.

60.      If any event occurs or has occurred that may delay the performance of any obligation under this Consent Decree, whether or not caused by a force majeure event, Mosaic shall provide notice orally or by electronic or facsimile transmission as soon as possible, as provided in Section XV (Notices) of this Consent Decree, but not later than seven (7) Days after the time when Mosaic first knew that the event might cause a delay. Within ten (10) Days thereafter, Mosaic shall provide written notice to EPA and FDEP with an explanation and description of the reasons for the delay; the anticipated duration of the delay; all actions taken or to be taken to prevent or minimize the delay; a schedule for implementation of any measures to be taken to prevent or mitigate the delay or the effect of the delay; Mosaic’s rationale for attributing such delay to a force majeure event if it intends to assert such a claim; and a statement as to whether, in the opinion of Mosaic, such event may cause or contribute to an endangerment to public health, welfare or the environment. Mosaic shall include with any notice all available documentation supporting a claim that the delay was attributable to a force majeure event. Mosaic shall be deemed to know of any circumstance of which Mosaic, any entity controlled by Mosaic, or Mosaic’s contractors knew or reasonably should have known. Failure to comply with the above requirements regarding an event shall preclude Mosaic from asserting any claim of force majeure regarding that event, provided, however, that if EPA, despite the late notice, is able to assess to its satisfaction whether the event is a force majeure under Paragraph 59 and whether Mosaic has exercised its best efforts under Paragraph 60, EPA may, in its

– 53 –

unreviewable discretion, excuse in writing Mosaic’s failure to submit timely notices under this Paragraph.

61.      If EPA, after consultation with FDEP, agrees that the delay or anticipated delay is attributable to a force majeure event, the time for performance of the obligations under this Consent Decree that are affected by the force majeure event will be extended by EPA, after consultation with FDEP, for such time as is necessary to complete those obligations. An extension of the time for performance of the obligations affected by the force majeure event shall not, of itself, extend the time for performance of any other obligation. If EPA, after consultation with FDEP, agrees that the delay is attributable to a force majeure event, EPA will notify Mosaic in writing of the length of the extension, if any, for performance of the obligations affected by the force majeure event.

62.      If EPA, after consultation with FDEP, does not agree that the delay or anticipated delay has been or will be caused by a force majeure event, EPA will notify Mosaic in writing of its decision.

63.      If Mosaic elects to invoke the dispute resolution procedures set forth in Section XI (Dispute Resolution), it shall do so no later than fifteen (15) Days after receipt of EPA’s notice. In any such proceeding, Mosaic shall have the burden of demonstrating by a preponderance of the evidence that the delay or anticipated delay has been or will be caused by a force majeure event, that the duration of the delay or the extension sought was or will be warranted under the circumstances, that best efforts were exercised to avoid and mitigate the effects of the delay, and that Mosaic complied with the requirements of Paragraphs 59 and 60, above. If Mosaic carries this burden, the delay at issue shall not be a violation by Mosaic of the affected obligation of this Consent Decree identified to EPA and the Court.

– 54 –

XI. DISPUTE RESOLUTION

64.      Unless otherwise expressly provided for in this Consent Decree, the dispute resolution procedures of this Section shall be the exclusive mechanism to resolve all disputes arising under or with respect to this Consent Decree. Mosaic’s failure to seek resolution of a disputed issue under this Section shall preclude Mosaic from raising any such issue as a defense to an action by the United States or FDEP to enforce any obligation of Mosaic arising under this Consent Decree.

65.      Informal Dispute Resolution.  Any dispute subject to Dispute Resolution under this Consent Decree shall first be the subject of informal negotiations, which may include anythird-party assisted,non-binding alternative dispute resolution process agreeable to the Parties. Mosaic shall submit a written Notice of Dispute to both the United States and FDEP within thirty (30) Days after receiving written notice from EPA (or FDEP with respect to Section VII (Supplemental Environmental Projects)) of a decision that Mosaic disputes. The dispute shall be considered to have arisen on the later of the dates that the United States or FDEP receives a written Notice of Dispute. Such Notice of Dispute shall state clearly the matter in dispute. The period of informal negotiations shall not exceed twenty (20) Days from the date that the dispute arises, unless that period is modified by written agreement between the United States (or FDEP with respect to Section VII (Supplemental Environmental Projects)) and Mosaic. If the Parties cannot resolve a dispute by informal negotiations, then the position of EPA, after consultation with FDEP, or of FDEP with respect to Section VII (Supplemental Environmental Projects, shall be considered binding, unless Mosaic invokes formal dispute resolution procedures as provided in the following Paragraph.

– 55 –

66.      Formal Dispute Resolution.  If Mosaic elects to invoke formal dispute resolution, Mosaic shall, within thirty (30) Days after the conclusion of the informal negotiation period, submit to EPA and FDEP, or of FDEP with respect to Section VII (Supplemental Environmental Projects, a written Statement of Position regarding the matter in dispute. The Statement of Position shall include, but need not be limited to, any factual data, analysis, or opinion supporting Mosaic’s position and any supporting documentation relied upon by Mosaic.

67.      EPA, after consultation with FDEP, or FDEP with respect to Section VII (Supplemental Environmental Projects), shall submit its Statement of Position withinforty-five (45) Days of receipt of Mosaic’s Statement of Position. The EPA or FDEP Statement of Position shall include or clearly reference, but need not be limited to, any factual data, analysis, or opinion supporting that position and any supporting documentation relied upon by EPA or FDEP. Where appropriate, EPA (or FDEP with respect to Section VII (Supplemental Environmental Projects)) may allow submission of supplemental statements of position by the Parties to the dispute. The EPA or FDEP Statement of Position shall be binding on Mosaic unless Mosaic files a motion for judicial review of the dispute in accordance with the following Paragraph.

68.      Mosaic may seek judicial review of the dispute by filing with the Court and serving on the United States and FDEP, in accordance with Section XV (Notices) of this Consent Decree, a motion requesting judicial resolution of the dispute. The motion must be filed within thirty (30) Days of receipt of EPA’s Statement of Position pursuant to the preceding Paragraph. The motion shall contain a written statement of Mosaic’s position on the matter in dispute, including any supporting factual data, analysis, opinion, or documentation, and shall set

– 56 –

forth the relief requested and any schedule within which the dispute must be resolved for orderly implementation of the Consent Decree.

69.      The United States, after consultation with FDEP, or FDEP with respect to Section VII (Supplemental Environmental Projects), shall respond to Mosaic’s motion within the time period allowed by the Local Rules of this Court. Mosaic may file a reply memorandum to the extent permitted by the Local Rules.

70.      Standard of Review

a.  Disputes Concerning Matters Accorded Record Review.  In any dispute brought under this Section pertaining to the adequacy or appropriateness of plans, procedures to implement plans, schedules or any other items requiring approval by EPA under this Consent Decree; the adequacy of the Work performed pursuant to this Consent Decree; and all other disputes that are accorded review on the administrative record under applicable principles of administrative law, EPA shall compile an administrative record of the dispute containing all Statements of Position, including supporting documentation and referenced data or information, and Mosaic shall have the burden of demonstrating, based on the administrative record, that the position of the United States is arbitrary and capricious or otherwise not in accordance with law.

b.  In any other dispute brought under this Section, Mosaic shall bear the burden of demonstrating that its position complies with and furthers the objectives of this Consent Decree.

71.      The invocation of dispute resolution procedures under this Section shall not, by itself, extend, postpone, or affect in any way any obligation of Mosaic under this Consent Decree, unless and until final resolution of the dispute so provides or unless ordered by the Court. Stipulated penalties with respect to the disputed matter shall continue to accrue from the

– 57 –

first Day of noncompliance, but payment shall be stayed pending resolution of the dispute as provided in Paragraph 54. If Mosaic does not prevail on the disputed issue, stipulated penalties shall be assessed and paid as provided in Section IX (Stipulated Penalties).

XII. INFORMATION COLLECTION AND RETENTION

72.      The United States, FDEP, and their representatives, including attorneys, contractors, and consultants, shall have the right of entry into any of Mosaic’s Florida Facilities, at all reasonable times, upon presentation of appropriate identification, to:

data or other information underlying the submission of any Report required pursuant to Section VIII (Reporting Requirements)) in its or its contractors or agents possession or control, or that come into its or its contractors’ or agents’ possession or control and that relate to Mosaic’s performance of its obligations under this Consent Decree or adherence to the requirements associated with the management of waste materials allowed under Paragraphs 15 through 18 for a period of five (5) years after the creation of such documents, records or other information. Thisinformation-retention requirement shall apply regardless of any contrary corporate or institutional policies or procedures. At any time during thisinformation-retention period, upon request by the United States or FDEP, Mosaic shall provide copies of any documents, records, or other information required to be maintained under this Paragraph.

75.      At the conclusion of theinformation-retention period provided in the preceding Paragraph, Mosaic shall notify the United States and FDEP at least ninety (90) Days prior to the destruction of any documents, records, or other information subject to the requirements of the preceding Paragraph and, upon request by the United States or FDEP, Mosaic shall deliver any such documents, records, or other information to EPA or FDEP. Mosaic shall not dispose of materials following the expiration of its five (5) year retention period more often than once a year.

76.      In connection with any request for documents, records, or other information pursuant to this Consent Decree, Mosaic may assert that certain documents, records, or other information are privileged under theattorney-client privilege or any other privilege recognized by federal law, provided that Mosaic shall not assert a legal privilege for any data, records or information (excluding legal advice) generated or received in connection with Mosaic’s obligations pursuant to the requirements of this Consent Decree. If Mosaic asserts a privilege, it

– 59 –

shall provide the following: (1) the title of the document, record, or information; (2) the date of the document, record, or information; (3) the name and title of each author of the document, record, or information; (4) the name and title of each addressee and recipient; (5) a description of the subject of the document, record, or information; and (6) the privilege asserted by Mosaic. If Plaintiffs and Mosaic disagree as to whether a particular document or record is privileged, Mosaic shall deliver such document or record to the United States or the FDEP unless it invokes dispute resolution pursuant to Section XI (Dispute Resolution), in which case, Mosaic shall not have an obligation to deliver such document or record until a final determination is made, pursuant to the procedures set forth in Section XI (Dispute Resolution), that such document or record is not privileged.

77.      Mosaic may also assert that information provided pursuant to this Consent Decree is protected as Confidential Business Information (CBI) under the criteria and procedures set forth in 40 C.F.R. Part 2, provided that: (a) Mosaic shall not assert a CBI claim with respect to any physical, sampling, monitoring, or analytical data other than data related to: (i) development of new or modified products; (ii) development of new or modified production processes; (iii) production materials or analyses collected for quality control or other manufacturing purposes; or (iv) analyses undertaken for competitive business purposes; and (b) Mosaic shall not assert a CBI claim for Financial Assurance information required to be provided pursuant to Paragraphs 10.e, 15.(e) and 32 of Appendix 2 of this Consent Decree. If Mosaic claims any information related to Financial Assurance submissions and Cost Estimates is CBI, Mosaic shall submit two versions, one version with the CBI material redacted, and so identified in the document, which will be publicly available, and the second version will contain the CBI material.

– 60 –

78.      This Consent Decree in no way limits or affects any right of entry and inspection, or any right to obtain information, held by the United States or FDEP pursuant to applicable federal or state laws, regulations, or permits, nor does it limit or affect any duty or obligation of Mosaic to maintain documents, records, or other information imposed by applicable federal or state laws, regulations, or permits.

XIII. EFFECT OF SETTLEMENT/RESERVATION OF RIGHTS

79.      This Consent Decree resolves the civil claims of the United States and FDEP against Mosaic, and, as to any liability arising out of Mosaic’s liability only, The Mosaic Company, for the violations at the Facilities alleged in the Complaint filed in this action through the date of the lodging of the Consent Decree. This Consent Decree also resolves such claims, if any, of the United States and FDEP against the corporate officers, directors, and employees, acting in their capacities as such, of Mosaic or The Mosaic Company, but only as to liability arising out of Mosaic’s liability. For continuing violations alleged in the Complaint, provided that Mosaic complies with this Consent Decree at a Facility, as set forth in Paragraph 81, from the date of lodging of the Consent Decree through its Effective Date, these claims shall also be resolved through the Effective Date of this Consent Decree, as of the Effective Date, for that Facility; and, provided that Mosaic complies with the Consent Decree at a Facility from the Effective Date of this Consent Decree through the date of termination of this Consent Decree for that Facility pursuant to Section XIX (Termination), these claims shall be finally resolved as of the date the Consent Decree terminates for that Facility.

80.      Provided that Mosaic is in compliance with this Consent Decree, and subject to the reservation set forth below, Plaintiffs covenant not to sue or take administrative action under

– 61 –

Section 3008(a) of RCRA, 42 U.S.C. § 6928(a), or its state counterpart, seeking to require Mosaic’s Facilities to comply with the RCRA Requirements, with respect to: (a) the generation, treatment, storage, transport, management, and disposal ofBevill-Exempt Wastes that have been commingled with hazardous wastes or otherwise managed in violation of law as alleged in the Complaint, and that are resolved in accordance with Paragraph 79; and (b) wastes that Paragraph 15-18 of this Consent Decree allow to be input to Upstream Operations or Downstream Operations or managed in Recovery Units or withBevill-Exempt Wastes or transferred among Mosaic’s Florida Facilities. Nothing in this Paragraph, however, shall affect Plaintiffs’ rights to determine and require necessary Corrective Action Work in accordance with Paragraphs 20 and 23 of this Consent Decree, or to restrict Non-CD Corrective Action that may be required at a Facility pursuant to Plaintiffs’ residual authorities under federal, state, and local laws.

81.      The resolution under this Section XIII (Effect of Settlement/Reservation of Rights) of the Plaintiffs’ civil claims set forth in the Complaint and the Plaintiffs’ covenants not to sue are expressly conditioned upon Mosaic’s timely and satisfactory compliance with the requirements of this Consent Decree. For the purposes of this Paragraph (and Paragraphs 79 and 80), and with respect to those wastes that Paragraphs 15 through 18 allow to be input to Upstream Operations or Downstream Operations, managed in Recovery Units or together withBevill-Exempt Wastes, or transferred among Mosaic’s Florida Facilities, compliance with the Continuing Compliance Criteria set forth in Paragraph 32 constitutes compliance with this Consent Decree.

82.      The United States and FDEP reserve all legal and equitable remedies available to enforce the provisions of this Consent Decree, and Mosaic reserves all legal and equitable defenses available to it in the defense of any such enforcement. This Consent Decree shall not

– 62 –

be construed to limit the rights of the United States or FDEP to obtain penalties or injunctive relief under the federal and state environmental statutes or their implementing regulations, or under other federal or state law, regulations, or permit conditions, including Section 3008(h) of RCRA, 42 U.S.C. § 6928(h), except as expressly specified in Paragraphs 79 and 80, and Mosaic in any such action shall not assert any defense based upon the contention that such claims raised by the Plaintiffs were or should have been brought in the instant case under principles of waiver, res judicata, collateral estoppel, issue preclusion, claim preclusion,claim-splitting, or other such defense. The United States and FDEP further retain all authority and reserve all rights to take any and all actions authorized by law to protect human health and the environment, including Corrective Action Work and Non-CD Corrective Action, and all legal and equitable remedies to address any imminent and substantial endangerment to the public health or welfare or the environment arising at, or posed by, Mosaic’s Facilities, whether related to the violations addressed in this Consent Decree or otherwise.

83.      This Consent Decree is not a permit, or a modification of any permit, under any federal, State, or local law or regulation. While this Consent Decree resolves the Parties’ dispute regarding the violations alleged in the Complaint as set forth in Paragraph 79, compliance with the terms of this Consent Decree does not guarantee compliance with all applicable federal, state, or local laws or regulations. Except as provided in Paragraphs 34, 79 and 80 of this Consent Decree, Mosaic is not relieved of its obligation to achieve and maintain compliance with all applicable federal, State, and local laws, regulations, and permits; Mosaic’s compliance with this Consent Decree shall be no defense to any action commenced by Plaintiffs pursuant to any such law, regulation, or permit, except as expressly specified in Paragraphs 34, 79 and 80.

– 63 –

84.      This Consent Decree does not limit or affect the rights of the Parties against any third-parties (persons not a Party to this Consent Decree), nor does it limit the rights of third-parties except as otherwise provided by the doctrine of federal preemption or by other applicable principles of law or precedent.

85.      This Consent Decree shall not be construed to create rights or obligations in, or grant any cause of action to, any third-party.

86.      Nothing in the Complaint filed in this action or in this Consent Decree, including the execution and implementation of this Consent Decree, shall constitute an admission by Mosaic of any violation of the RCRA Requirements or of any of the allegations of the Complaint. Mosaic reserves all rights to dispute the factual and legal representations of the Complaint and Consent Decree except in an action to enforce this Consent Decree by a Party. The terms of this Consent Decree may not be used as evidence in any litigation between the Parties except (a) pursuant to Section XI (Dispute Resolution), (b) in an action to enforce this Consent Decree, or (c) in an action by Plaintiffs in which Mosaic asserts a defense based on this Consent Decree.

XIV. COSTS

87.      The Parties shall bear their own costs of this action, including attorneys’ fees, except that the United States and FDEP shall be entitled to collect costs (including attorneys’ fees) incurred in any action necessary to access Financial Assurance pursuant to Paragraph 26 and Appendix 2 (Financial Assurance) of this Consent Decree, or to collect any portion of the civil penalty or any stipulated penalties or other costs due under this Consent Decree but not paid by Mosaic.

90.      Notices submitted pursuant to this Section shall be deemed submitted upon electronic transmission, unless otherwise provided in this Consent Decree or by mutual agreement of the Parties in writing.

XVI. EFFECTIVE DATE

91.      The Entry Date of this Consent Decree shall be the date of a Final Order by which this Consent Decree is entered by the Court or by which a motion to enter the Consent Decree is granted, whichever occurs first, as recorded on the Court’s docket. The Effective Date of this Consent Decree shall be the later of the Entry Date of this Consent Decree or the Entry Date of the Consent Decree resolving claims by the United States and the Louisiana Department of Environmental Quality against Mosaic relating to Mosaic’s facilities in Louisiana. The filing or

– 67 –

pendency of an appeal of the Court’s entry of this Consent Decree shall not stay the Effective Date, except as may be otherwise determined pursuant to Paragraph 93 (Modification).

In the event that either Consent Decree is not entered by the Court, the Parties shall jointly stipulate to stay any previously entered Consent Decree. Notwithstanding the foregoing, Mosaic hereby agrees that it shall be bound from the date of its execution of this Consent Decree to perform obligations scheduled in this Consent Decree to occur prior to the Effective Date.

XVII. RETENTION OF JURISDICTION

92.      The Court shall retain jurisdiction over this case until termination of this Consent Decree for all Facilities, pursuant to Section XIX (Termination), for the purpose of resolving disputes arising under this Consent Decree (including disputes under any Trust Agreements entered pursuant hereto) or entering orders modifying this Consent Decree, pursuant to Sections XI (Dispute Resolution) and XVIII (Modification), or effectuating or enforcing compliance with the terms of this Consent Decree.

XVIII. MODIFICATION

93.      The terms of this Consent Decree may be modified only by a subsequent written agreement of the Parties to this Consent Decree as set forth herein. Any modifications to the provisions of Appendices 1 through 7 hereto, and any other modifications to any other provisions of this Consent Decree that do not constitute a material change to this Consent Decree, may be made without approval by the Court upon written agreement between Mosaic and the United States, after consultation with FDEP. Any modifications to the provisions of Appendices 8 and 9 may be made without approval by the Court upon written agreement between Mosaic and FDEP, after consultation with the United States. Any such changes shall become enforceable under this Consent Decree upon execution by Mosaic and the United States (for changes to the Consent

– 68 –

Decree or Appendices 1 through 7) or Mosaic and FDEP (for changes to Appendices 8 and 9), shall be made available to the public by EPA and FDEP (except to the extent such changes contain information determined to be CBI pursuant to Paragraph 77 and 40 C.F.R. Part 2,) and shall periodically be filed by EPA or FDEP with the Court. Any other modifications agreed to by the Parties shall be effective only upon approval by the Court. Except as otherwise provided in this Paragraph and Paragraph 95, a Party’s refusal to agree to a modification of this Consent Decree shall be subject to dispute resolution, but a Party seeking judicial review of such a refusal shall bear the burden of demonstrating that it is entitled to the requested modification based on a significant change in factual conditions or the law or other reason that would make inequitable the continued application of the Consent Decree without the modification sought.

94.      In the event that a potential transferee under Section II of this Consent Decree has agreed to become a party to this Consent Decree and subject to all its terms and provisions, it may do so upon written approval of the United States pursuant to Section II (Applicability) of this Consent Decree and Section XVIII (Modification), without further order from the Court, in which event a supplemental signature page will be affixed to this Consent Decree and filed with the Court.

XIX. TERMINATION

95.      Periodic Review of Work Status.    At least once every three (3) years, and more often if the Parties so agree, the Parties shall meet to review the status of the Work and to evaluate whether discrete portions of the Work have either been completed or may be accomplished and supervised under an EPA or FDEP administrative order or permit in lieu of this Consent Decree. If all Parties agree to such a modification, such agreement shall be memorialized in a written modification to this Consent Decree pursuant to Section XVIII

– 69 –

(Modification) and shall not require judicial approval. If the Parties agree that such modifications allow this Consent Decree to be terminated as to one or more Facilities, the Parties shall submit, for the Court’s approval, a joint stipulation terminating the Consent Decree for the relevant Facilities. The Parties’ inability to reach agreement under this Paragraph shall not be subject to dispute resolution or judicial review.

96.      Completion of Work.    Within ninety (90) Days after Mosaic concludes that all Work required under this Consent Decree has been fully performed at a Facility, EPA and/or FDEP may conduct an inspection of the Facility to be attended by EPA, FDEP and Mosaic at a mutually agreeable time. Following the inspection, and correction of any problems or deficiencies noted by EPA, after consultation with FDEP, Mosaic shall submit one or more written reports by a third-party registered professional engineer in the relevant technical field, certifying compliance with Section V (Compliance Requirements) of this Consent Decree that the Work has been completed in full satisfaction of the requirements of this Consent Decree. The reports shall indicate the case name and civil action number, and shall be submitted, together with a request for Acknowledgment of Completion, in accordance with Section VIII (Reporting Requirements) of this Consent Decree.Third-party engineer certification of any of the written reports may be waived at EPA’s discretion, after consultation with FDEP.

97.      If, after review of the written report(s) and certification and consultation with FDEP, EPA determines that any portion of the Work has not been completed in accordance with this Consent Decree, EPA will notify Mosaic in writing of the activity(ies) and/or obligation(s) that must be undertaken to complete the Work. EPA will set forth in the notice a schedule for performance of the activity(ies) and/or obligation(s) required under the Consent Decree, or will require Mosaic to submit a schedule for EPA approval pursuant to Section V (Compliance

– 70 –

Requirements) of this Consent Decree. Mosaic shall perform all activities described in the notice in accordance with the specifications and schedules established therein, subject to Mosaic’s right to invoke the dispute resolution procedures set forth in Section XI (Dispute Resolution) of this Consent Decree.

98.      If EPA concludes, based on the initial or any subsequent request for an Acknowledgment of Completion by Mosaic, and after reasonable opportunity for review and comment by FDEP, that the Work has been fully performed in accordance with this Consent Decree, EPA will so notify Mosaic in writing, which notice shall constitute the Acknowledgment of Completion.

99.      Termination.    After Mosaic has completed the requirements set forth in Paragraphs 96 and 97 of this Section, has obtained an Acknowledgment of Completion, has complied with all other requirements of this Consent Decree, and has paid the civil penalty and any accrued stipulated penalties as required by this Consent Decree, Mosaic may serve upon the United States and FDEP a Request for Termination, stating that Mosaic has satisfied those requirements, together with all necessary supporting documentation. A Request for Termination may address one or more of Mosaic’s Facilities.

100.    Following receipt by the United States and FDEP of Mosaic’s Request for Termination, the Parties shall confer informally concerning the Request and any disagreement that the Parties may have as to whether Mosaic has satisfactorily complied with the requirements for termination of this Consent Decree. If the United States, after consultation with FDEP, agrees that the Consent Decree may be terminated for one or more Facilities, the Parties shall submit, for the Court’s approval, a joint stipulation terminating the Consent Decree as to the relevant Facilities.

– 71 –

101.    If the United States, after consultation with FDEP, does not agree that the Consent Decree may be terminated as to one or more Facilities, Mosaic may invoke Dispute Resolution under Section XI of this Consent Decree. However, all time periods and deadlines established under Section XI (Dispute Resolution) shall be extended by sixty (60) Days, or more by the agreement of the Parties.

XX. PUBLIC PARTICIPATION

102.    This Consent Decree shall be lodged with the Court for a period of not less than thirty (30) Days for public notice and comment in accordance with 28 C.F.R. § 50.7. The United States reserves the right to withdraw or withhold its consent if the comments regarding the Consent Decree disclose facts or considerations indicating that the Consent Decree is inappropriate, improper, or inadequate. Mosaic and The Mosaic Company consent to entry of this Consent Decree without further notice and agree not to withdraw from or oppose entry of this Consent Decree by the Court or to challenge any provision of the Consent Decree, unless the United States has notified Mosaic in writing that it no longer supports entry of the Consent Decree.

XXI. SIGNATORIES/SERVICE

103.    Each undersigned representative of Mosaic and The Mosaic Company, the Assistant Attorney General for the Environment and Natural Resources Division of the Department of Justice, or his designee, and the Secretary of the Florida Department of Environmental Protection certifies that he or she is fully authorized to enter into the terms and conditions of this Consent Decree and to execute and legally bind the Party he or she represents to this document.

– 72 –

104.    This Consent Decree may be signed in counterparts, and its validity shall not be challenged on that basis. Mosaic and The Mosaic Company agree to accept service of process by mail with respect to all matters arising under or relating to this Consent Decree and to waive the formal service requirements set forth in Rules 4 and 5 of the Federal Rules of Civil Procedure and any applicable Local Rules of this Court including, but not limited to, service of a summons.

XXII. INTEGRATION

105.    This Consent Decree and its Appendices constitute the final, complete, and exclusive agreement and understanding among the Parties with respect to the settlement embodied in the Consent Decree and supersedes all prior agreements and understandings, whether oral or written, concerning the settlement embodied herein. Other than the Appendices, which are attached to and incorporated in this Consent Decree, no other document, nor any representation, inducement, agreement, understanding, or promise, constitutes any part of this Consent Decree or the settlement it represents, nor shall it be used in construing the terms of this Consent Decree.

XXIII. FINAL JUDGMENT

106.    Upon approval and entry of this Consent Decree by the Court, this Consent Decree shall constitute a final judgment of the Court as to the United States, FDEP, Mosaic and The Mosaic Company. The Court finds that there is no just reason for delay and therefore enters this judgment as a final judgment under Fed. R. Civ. P. 54 and 58.

APPENDIX 1

APPENDIX 1- OPERATING AND CLOSURE REQUIREMENTS FOR THE

PHOSPHORIC ACID PRODUCTION INDUSTRY IN FLORIDA

ATTACHMENT A: SITE ASSESSMENT, REPORTING, AND CORRECTIVE ACTION

SAMPLING AND ANALYSIS WORKPLAN

Defendant’s obligations pursuant to this Attachment A are governed by Paragraphs 20 and 23 of the Consent Decree.

1)	The Defendant shall submit to FDEP and/or EPA for approval an Outline for a Sampling and Analysis Workplan (“Outline”), for carrying out the required monitoring, testing, analysis, and reporting.
2)	The Defendant shall submit to FDEP and/or EPA a Sampling and Analysis Workplan (“Workplan”), unless Defendant has already submitted a Sampling and Analysis Workplan that has been approved by FDEP and/or EPA and is consistent with this Attachment.
3)	The Sampling and Analysis Workplan shall be designed to determine the presence, magnitude, extent, direction, and rate of movement of any hazardous waste, hazardous constituents, and/or constituents of concern (“COC”) within and beyond the Facility boundary. COCs shall be limited to those contaminants that are reasonably likely to be found at the Facility. The Workplan shall document the procedures the Defendant shall use to assess sampling and analysis data that is generated and that relate to the purposes of this Attachment. The Workplan shall also document the procedures the Defendant shall use to conduct those activities necessary to: characterize the source(s) of contamination; characterize the potential pathways of contaminant migration; define the degree and extent of contamination; and identify actual or potential human and/or ecological receptors. The Defendant may implement the work contained in the Workplan in a multi-phased approach. A specific schedule for expeditious implementation of all activities shall be included in the Workplan. At a minimum, the Workplan for assessment shall include the following[All requirements below would be Facility-specific]:

(a) A sediment and/or soil, as appropriate, sampling and analysis section to collect and analyze representative sediment and/or soil samples to determine the nature and extent of potential contamination, both vertically and horizontally. Areas of sampling shall include process areas, areas of historical spills and/or historical contamination, areas of waste management, other Facility operation areas (to be defined), stormwater and non-Process Wastewater ditches and ponds, and ditches associated with National Pollutant Discharge Elimination System (“NPDES”) outfall(s). The Workplan must define the number, location, and depth of the samples, and the parameters for analysis. The number of samples shall be

1

Attachment A: Site Assessment, Reporting, and Corrective Action

	sufficient to produce a 95% confidence level that the results are representative of the environmental conditions found at each location.

Attachment A: Site Assessment, Reporting, and Corrective Action

APPENDIX A-1

Screening Criteria- Action Levels for Assessment of Corrective Action

I. Definition

Action levels are conservative health-based concentrations of hazardous wastes and/or hazardous constituents determined to be indicators for the protection of human health or the environment. Action levels shall be set by FDEP and/or EPA for all hazardous wastes and/or hazardous constituents identified through Attachment A which FDEP and/or EPA has reason to believe may have been released in soils, sediments, or Surface Water, or in Groundwater (at or beyond the zone of discharge) from the Facility into the environment. Should the concentration of hazardous wastes and/or hazardous constituents in soils, sediments, or Surface Water, or in Groundwater (at or beyond the zone of discharge) exceed the action levels established for any environmental medium, FDEP and/or EPA may require the Respondent to conduct a Risk Assessment and/or perform Corrective Action. If FDEP and/or EPA determine that concentrations of hazardous wastes and/or hazardous constituents released from the Facility, below established action levels, may pose a substantial threat to human health or the environment given site-specific exposure conditions, cumulative effects, ecological concerns or other factors, then FDEP and/or EPA may require a Risk Assessment pursuant to Paragraph 17b of Attachment A.

Action levels shall be concentration levels that satisfy the following criteria.

II. Soils

Action levels for constituents in soils shall be derived from the most stringent of levels established by FDEP or EPA’s Regional Screening Levels. Pursuant to FDEP’s Corrective Action Program, industrial soil levels may be applied for onsite soil as long as the current site use remains industrial.

III.  Sediment

Action levels are not available for constituents in sediment. Screening levels (not action levels) for constituents in sediment shall be concentrations that will be established using:

1.        Sediment Quality Assessment Guidelines (SQAGs). The marine and freshwater guidelines are located at:http://www.dep.state.fl.us/water/monitoring/sediments.htm

2.        For those parameters for which there is no SQAG, the latest Sediment and Soil Screening Values for ecological risks as calculated by FDEP and/or EPA (Region 4 Cleanup Ecological and Health Risk Assessment Bulletins (RAGS Supplement)) will be applied as screening levels (not action levels) to identify site-specific constituents for

9

Appendix A-1: Screen Criteria – Action Levels for Assessment of Corrective Action

which action levels shall be established.

IV. Groundwater

Action levels for constituents in Groundwater at or beyond the zone of discharge shall be concentrations specified as:

1.        Maximum Contaminant Levels (“MCLs”) established at 40 C.F.R. Part 141, or the applicable state law or Facility permit requirements for the State in which the Facility is located, these action levels must meet appropriate aquatic water quality criteria if it is determined through the process outlined in Attachment A that Groundwater has the potential to impact Surface Water.

2.        For facilities where the MCL is the most stringent standard for individual contaminants, if the Natural Background exceeds the MCL, representative Natural Background will be the default Groundwater standard, unless the applicable state law or Facility permit is more stringent than Natural Background for that contaminant, in which case the applicable state law or Facility permit will provide the appropriate standard for that contaminant.

V. Surface Water

Action levels for constituents in Surface Water shall be concentrations specified as:

1.        The more stringent of FDEP and/or EPA Surface Water Screening Values for ecological risk;

2.        If action levels are not available from the screening values, Ambient Water Quality Criteria as established by the Clean Water Act will be used.

APPENDIX 1- OPERATING AND CLOSURE REQUIREMENTS FOR THE

PHOSPHORIC ACID PRODUCTION INDUSTRY IN FLORIDA

ATTACHMENT B: GROUNDWATER AND ZONE OF DISCHARGE REQUIREMENTS

I. Zone of Discharge Requirements

A. Establishment of the Zone of Discharge

Subject to the modification provisions set forth in Section I.B. (Modifications to an Established Zone of Discharge or Monitoring Requirements) of this Attachment:

(1) No zone of discharge shall be allowed into potable Groundwater, unless authorized by FDEP (including by permit) before the effective date of the Consent Decree or by this Attachment. Unless state law or a state-issued permit provides otherwise, zones of horizontal discharge shall extend no farther than to the Facility’s current property boundary or the existing permitted boundary, where a permit applies, unless, after consultation with Mosaic, FDEP determines that a smaller zone of discharge will afford necessary protection to the designated use of adjacent surface Waters outside the zone of discharge at a cost that is commensurate with the benefits to the public of such protection. Vertical zones of discharge shall be maintained where permitted prior to the date of entry of the Consent Decree.

(2) Where multiple sites occur within close proximity, a single zone of discharge for the sites may be established at the discretion of FDEP and/or EPA.

(3) Within the zone of discharge, if a Statistically Significant increase in contaminant concentration (including corrosivity) in Groundwater is discovered, which EPA or FDEP determines constitutes an imminent and substantial endangerment to human health and/or the environment, then the hazard shall be addressed in accordance with Section I. D. (Zone of Discharge-Corrective Action) of this Attachment.

B. Modifications to an Established Zone of Discharge or Monitoring Requirements

(1) At any time, FDEP and/or EPA, after consultation with each other, may revise the zone of discharge and/or monitoring requirements for any of the reasons described in (1)(a) through (e) of this Section. Also, Mosaic may petition for a modification in the zone of discharge and/or monitoring requirements for any of the reasons described in (1)(a) through (e) of this Section.

(a) Monitoring data indicate that the discharge plume has resulted or may foreseeably result in a violation of applicable water quality standards beyond the boundary of the existing zone of discharge;

(b) Continuation of the existing zone of discharge will impair the designated use of underground sources of drinking water or the Surface Waters immediately affected by the Groundwater;

(c) Continuation of the existing zone of discharge may result in an imminent and substantial

11

Appendix B: Groundwater and Zone of Discharge Requirements

endangerment to human health or the environment;

(d) The monitoring data provided by Mosaic are inadequate to allow a determination of compliance with applicable zone of discharge limitations and the owner fails to provide reasonable additional data requested by FDEP and/or EPA; or

(e) A change in the chemical, physical, or microbiological composition, or the volume or the location of the discharge, requires a change in the zone of discharge or the monitoring scheme to assure compliance.

(f) If FDEP determines that other information is necessary to ascertain if a modification to the zone of discharge is warranted, Mosaic must submit such additional information upon request.

Mosaic also shall provide any such additional information requested by EPA.

(2)   Mosaic may petition FDEP in writing, with a copy provided to EPA, to extend its zone of discharge for certain specified water quality parameters. FDEP, in consultation with EPA and pursuant to Florida Administrative Code 62-520.470, Modification Procedures for Zones of Discharge or Monitoring Requirements, shall approve such extension if Mosaic affirmatively demonstrates that conditions (a) through (d) below are met:

(a)        The discharge shall not significantly impair any designated use of the receiving ground water, or surface water;

(b)        The discharge shall not in the foreseeable future result in a violation of applicable ground water standards in a currently used source of drinking water outside the zone of discharge;

(c)          The discharge shall not prevent persons within the proposed zone of discharge from enjoying the reasonable and beneficial use of their property; and

(d)          The economic and social benefits of a zone of discharge extending beyond the property boundary outweigh the economic, environmental, and social costs resulting from the extended zone of discharge, taking into account the feasibility of preventative measures or corrective actions.

(e)   Mosaic shall provide a copy of the petition to the property owners of the property underlain by the proposed extended zone of discharge by certified mail return receipt requested within 10 Days from submitting the petition to FDEP and EPA. A copy of each certified mail return receipt shall be provided to the appropriate permitting program in FDEP District office where the permit was issued.

(f) If FDEP determines that other information is necessary to ascertain if an extension to the zone of discharge is warranted, Mosaic must submit such additional information upon request.

Mosaic also shall provide any such additional information requested by EPA.

(3) Nothing in this Section shall limit or affect EPA’s assertion of its residual authorities to disapprove a revision or modification to a zone of discharge, notwithstanding approval by FDEP.

12

Appendix B: Groundwater and Zone of Discharge Requirements

EPA shall provide notice to Mosaic within 90 Days of FDEP approval if EPA does not concur with that decision.

(b) The reports must also include:

1. Monitor well location, construction, and the collection and testing of samples; and

2. Groundwater monitoring data displayed in graphic form for analyzing trends in water quality.

(c) Location of Monitoring Wells to Detect Migration of Contaminants. Unless Mosaic can demonstrate that detection can be obtained by a methodology other than the use of monitoring wells, wells shall be located as follows:

1. One up-gradient well located as close as possible to the site, without being affected by that site’s discharge, to determine the background, or Natural Background quality where available, of the Groundwater (background well);

14

Appendix B: Groundwater and Zone of Discharge Requirements

2. One well at the edge of the zone of discharge downgradient from the site (compliance wells);

3. Minimum of three (3) wells downgradient from the site and within the zone of discharge designed to detect the chemical, physical, and microbiological (if applicable) characteristics of the discharge plume (intermediate well); and

4. Such other wells as are dictated by the complexity of the hydrogeology of the site, the magnitude and direction of the plume or the likelihood of threat to the public health or the environment, to ensure adequate and reliable monitoring data in generally accepted engineering or hydrogeological practice.

(d) When requested by FDEP and/or EPA, Mosaic shall inform FDEP and/or EPA of the next sampling schedule so that a representative of either Agency may be present.

D. Zone of Discharge-Corrective Action Work

(1) Subject to Paragraphs 20 - 23 of the Consent Decree, Mosaic shall submit a Corrective Action Plan per D(3) below if FDEP and/or EPA determines that:

(a) The plume is confirmed beyond the zone of discharge, or

(b) The plume is likely in the foreseeable future to threaten to impair the designated use of an underground source of drinking water or Surface Water immediately affected by the Groundwater, or

(c) Within the zone of discharge, a Statistically Significant increase in contaminant concentration (including corrosivity) in Groundwater is discovered that presents a potential or actual hazard to human health and/or the environment outside of the zone of discharge.

(2) In the event (b) above applies, Mosaic may make a demonstration to FDEP and/or EPA that Corrective Action Work is not needed because the Groundwater impacts will not migrate to cause exceedances of applicable Groundwater standards and criteria beyond the permitted ZOD, or result in a violation of applicable Surface Water quality standards and criteria outside a permitted mixing zone.

(3) If a Corrective Action Plan is required pursuant to D(1) and Mosaic has not made a satisfactory demonstration under D(2), Mosaic shall submit, to FDEP and/or EPA a Corrective Action Plan pursuant to the requirements of Paragraph 18 of Appendix 1, Attachment A and Paragraph 27 of the Consent Decree.

(b) The water balance analysis for any Phosphogypsum Stack System shall indicate whether the system storage will be less than any of the following water balance targets:

1. At the beginning of the rainy season, the calculated 100-year, 24-hour rainfall event plus one-half the value for the 25-year, 24-hour rainfall event calculated (in inches) for the area where the Facility is located.

2. At the end of the rainy season, the 100-year, 24-hour rainfall event calculated (in inches) for the area where the Facility is located.

3. Water levels that exceed impoundment Maximum Design Levels at any time during a year.

If the water balance for any Phosphogypsum Stack System indicates that system storage is less than the water balance targets, the owner/operator must provide reasonable assurance that additional Process Wastewater consumption or management items, not already included as outputs in the water balance analysis, are readily available and capable of maintaining these water balance targets. Use of available storage within an Auxiliary Holding Pond, up to its Maximum Design Levels, may be used to provide this assurance.

(c) If the water balance indicates that at any time during the five (5)-year modeling period that Process Wastewater levels, in conjunction with additional available Process Wastewater consumption or management items will not meet the water balance targets, the owner/operator must provide additional Process Wastewater consumption or management items, and submit an alternatives plan and implementation schedule for approval by the FDEP and/or EPA for the additional consumption or management measures within ninety (90) days of submittal of the water balance analysis. The plan and schedule shall include, at a minimum, the following elements:

1. A listing and description of the additional Process Wastewater consumption or management items to be evaluated, including the identification of items that can be rapidly implemented to achieve the water balance targets;

II.  Cost Estimate

1.         Unless Defendant has provided the following submission to EPA prior to the Lodging of the Consent Decree and such submission has already been approved by EPA, within thirty-five (35) Days of the Lodging of this Consent Decree, Defendant shall submit to EPA for approval its initial Cost Estimate. In such case, and if the United States thereafter moves for entry of the Consent Decree, such motion shall be deemed approval of such initial Cost Estimate.

a.         The initial Cost Estimate, except as set out below in Paragraph 1.b for Financial Assurance being provided pursuant to Paragraph 10.a(1)(c), shall include a detailed written Cost Estimate for Phosphogypsum Stack System Closure and Long Term Care for each Facility, including but not limited to the cost of cover material, topsoil, seeding, fertilizing, mulching, labor, land surface care, and groundwater monitoring, collection and analysis and any other costs of compliance with Appendix 1, Attachment D. The Cost Estimate shall be calculated based on the point in time when the manner and extent of the operation of the Phosphogypsum Stack System would make the Phosphogypsum Stack System Closure and Long Term Care the most expensive. All Cost Estimates shall be based on what it would cost to hire a Third Party to complete Phosphogypsum Stack System Closure and Long Term Care in that year, except as

7

Mosaic Appendix 2

provided in Paragraph 1.c., below. Defendant shall include as part of its initial Cost Estimate the information specified in Attachments B and C of this Appendix.

b.         If Defendant is providing Financial Assurance in accordance with Paragraph 10.a(1)(c), then the initial Cost Estimate shall consist of a written Cost Estimate in the form specified in Attachments B and C. The Cost Estimate shall be calculated based on the December 2011 configuration of the Phosphogypsum Stack System(s) at the Operating Facilities and Closing Facilities (“Operating and Closing Facilities”) with the configuration of the Phosphogypsum Stack Systems for the Operating and Closing Facilities being updated every five (5) years thereafter (e.g., December 2016, December 2021). All Cost Estimates shall be based on what it would cost to hire a Third Party to complete Phosphogypsum Stack System Closure and Long Term Care in that year, except as provided in Paragraph 1.c., below.

c.         Subject to the conditions for access set forth below, Defendant may, if the conditions of this Paragraph 1.c. are met, provide a Cost Estimate that includes a cost for soil from a borrow area at the Facility, based on information provided by the Defendant describing the soil borrow areas to be used (e.g., location), in lieu of the cost to obtain soil from a Third Party. In that event, Defendant agrees that the United States and FDEP, in addition to their right to Financial Assurance as set forth in the Consent Decree, shall have the same legal right of access to and use of such soil, and any equipment necessary to access and process such soil, as Defendant would have. Defendant shall confirm with its Updated Cost Estimate submittal required under Paragraph 4, below, that the United States and FDEP continue to have a right to access and use the soil, that the soil available is sufficient for closure of the Phosphogypsum Stack System, and that Defendant knows of no reasons as to why the United States and FDEP, or their representatives, could not have access to and use of the borrow area(s) and soil. If, for any reason, Defendant or EPA determines that such access cannot be had, or that the available soil in the borrow area is insufficient for closure of the Phosphogypsum Stack System, then Defendant in its next annual Updated Cost Estimate or ninety (90) Days prior to Phosphogypsum Stack System Closure shall submit to EPA a revised Cost Estimate recalculating the soil cost either: (i) based on the cost of soil from a substitute borrow area at the Facility; (ii) based on the cost of soil and transportation from a substitute borrow area in the vicinity of the Facility on property owned by Mosaic Fertilizer, LLC; or (iii) if such substitute borrow area is not available, as a cost of a Third Party buying the soil for closure of the Phosphogypsum Stack System, and shall provide any additional or alternative Financial Assurance necessary to cover this cost. If Defendant has established Financial Assurance pursuant to Paragraph 10.a(1)(c) of this Appendix, then such additional cost shall be covered by the Corporate Guarantee until such time as the trust fund is fully funded. Nothing in this Paragraph 1.c. shall be construed as transferring to the United States, FDEP or their representatives any obligation that Defendant may have under the law, including permit requirements, to properly manage, close and/or remediate the soil borrow areas, or otherwise creating such obligations for the United States and/or FDEP, or their duly designated representatives.

d.         Lime treatment sludge ponds that are not part of the Defendant’s Phosphogypsum Stack System, and that are included in a National Pollutant Discharge Elimination System (NPDES) permit issued by FDEP, shall not be incorporated into the Cost Estimate and shall not be required to be covered by Financial Assurance under this Appendix.

2.        Each Cost Estimate shall be calculated as follows:

8

Mosaic Appendix 2

a.         In Current Dollars if Defendant provides Financial Assurance under Section III.A (Type A Financial Assurance), below; or

b.         In Current Dollars for Phosphogypsum Stack System Closure and using NPV for Long Term Care if Defendant provides the Financial Assurance pursuant to Section III.B (Type B Financial Assurance), below. NPV shall be calculated using the 30-Year Treasury Constant Maturity Rate, averaged for the previous twelve (12) months (using the average spot rate for each month) from the date of the annual Cost Estimates, and discounted over the time period for which Long Term Care is required.

3.        Defendant shall not include in any Cost Estimate any credit for salvage value or a zero cost for handling hazardous waste with potential future value, as set forth in 40 C.F.R. § 264.142(a)(3)&(4).

4.        Defendant shall submit the Updated Cost Estimate, together with supporting documentation, to EPA in the following manner:

a.         Defendant shall submit annually to EPA an Updated Cost Estimate reflecting inflationary adjustments to the initial Cost Estimate or prior Updated Cost Estimate, except as set forth in Paragraph 4.c, below. Such adjustment may be made by either method in Paragraph 4.a.(1) or 4a.(2) below, except as otherwise required in this Appendix:

(1) Recalculating the costs, in Current Dollars (i.e., OSWER Directive No. 9476.00-5, Section 4.4.1); or

(2) Using an inflationary factor derived from the most recent Implicit Price Deflator for the Gross National Product published by the U.S. Department of Commerce in itsSurvey of Current Business, in the manner as specified by 40 C.F.R. §§ 264.142(b) and 264.144(b). If the Cost Estimate is due by the end of February, the Defendant shall: (i) use the Implicit Price Deflator for the Gross National Product published for Q1, Q2 & Q3 of the prior year, calculate the change in the Deflator between Q1 and Q2, and the change in Deflator between Q2 and Q3, take the average of these values, and add this average to the Q3 Deflator to impute a Q4 Deflator; or (ii) if the Implicit Price Deflator for the Gross National Product has not been published for Q3 of the prior year by February 10 of the following year, Defendant shall calculate the change in the published Deflator between Q1 and Q2, adding this value both to the Deflator for Q2 to impute a Q3 Deflator and to the imputed Q3 Deflator to impute a Q4 Deflator. If Defendant calculates imputed Deflators by using an average of the change in Deflators from prior quarters, because the actual Implicit Price Deflator for Q3 or Q4 were not then available, annual inflationary adjustments in subsequent years shall be based on the actual Implicit Price Deflator, as and when published values become available. An example of the inflationary factor calculation is provided in Attachment B of this Appendix.

b.         Defendant shall submit for the Updated Cost Estimate, unless required to provide an Updated Cost estimate pursuant to Paragraph 4.c., below, a supplement to the Initial Closure Plan updating any new information (e.g., revised closure schedule) and Attachments B and C of this Appendix, except that if Defendant is providing Financial Assurance pursuant to Paragraph 10.a.(1)(c), then Defendant shall provide only Attachment B.

c.         Defendant shall:

(1) If providing Financial Assurance other than pursuant to Paragraph 10.a.(1)(c), submit every five (5) years for the annual Updated Cost Estimate, a Cost Estimate with supporting documentation and an updated Initial Closure Plan (if needed), reflecting cost

9

Mosaic Appendix 2

adjustments (e.g., revised treatment protocols, additional studies; treatment costs, material and labor cost increases, etc.) as specified in Paragraph 4.c.(3), below. Defendant shall provide the Updated Cost Estimate and associated documentation five (5) years after the submittal of the initial Cost Estimate (pursuant to Paragraph 1.a. of this Appendix). Defendant shall also provide such an Updated Cost Estimate for a Facility: (i) in the event of a re-evaluation of when the manner and extent of the operation of the Phosphogypsum Stack System makes the Phosphogypsum Stack System Closure and Long Term Care the most expensive; (ii) with the submittal of the Permanent Phosphogypsum Stack System Closure Plan as specified in Appendix 1, Attachment D of the Consent Decree; and (iii) thirty (30) Days prior to a Facility transfer with the information requested pursuant to Paragraph 35 of this Appendix.

(2) If providing Financial Assurance pursuant to Paragraph 10.a.(1)(c), submit every five (5) years for the annual Updated Cost Estimate, (i) an updated Initial Closure Plan, including detailed Cost Estimate information consistent with the level of detail in Section 3 (and associated Tables) and Attachment 1 (and associated Tables) of the draft 2012 Initial Closure Plans provided by Defendant to EPA and FDEP prior to the lodging of the Consent Decree and (ii) Attachments B and C. The updated Initial Closure Plan and Updated Cost Estimate shall reflect cost adjustments (e.g.,(as applicable), revised treatment protocols, additional studies; revised programmatic and administrative needs; treatment costs, material, and labor cost increases; etc.) and the configuration of the Phosphogypsum Stack System as of December of the prior year (e.g., stack height, acreage to be closed, number of side slope and/or toe drains, volume of process wastewater, leachate, and sludge (within the Phosphogypsum Stack System) to be managed, updated aerial photographs, updated engineering drawings of the Phosphogypsum Stack System, any new components (e.g., cooling pond, ditches)). Such costs shall be adjusted as specified in Paragraph 4.c.(3) below. Defendant shall provide the Updated Cost Estimate and Initial Closure Plan under this Paragraph in 2017, with subsequent Updated Cost Estimates and updated Initial Closure Plans every five (5) years thereafter (e.g., 2022, 2027). Defendant shall also provide such an Updated Cost Estimate for a Facility: (i) at least sixty (60) Days prior to the Defendant constructing a lateral expansion at a Facility referenced in Paragraph 29.b; (ii) with the submittal of the Permanent Phosphogypsum Stack System Closure Plan as specified in Appendix 1, Attachment D of the Consent Decree; and (iii) thirty (30) Days prior to a Facility transfer with the information requested pursuant to Paragraph 35 of this Appendix, unless such Updated Cost Estimate has been performed for such Facility within the prior two (2) years. The submittal of an Updated Cost Estimate under Paragraph 4.c.(2)(i)&(ii), above, shall not alter the five (5)-year schedule for receipt of an Updated Cost Estimate under this Paragraph.

(3) An Updated Cost Estimate submitted under this Paragraph 4.c. shall be adjusted by recalculating the costs, in Current Dollars, as set forth in Paragraph 4.a.(1), above.

(a) In the event a specific cost needed to prepare the Updated Cost Estimate has been updated pursuant to Paragraph 4.a.(1), above, within one (1) year, Defendant may adjust that specific cost pursuant to Paragraph 4.a.(2), above.

(b) In the event a specific cost needed to prepare the Updated Cost Estimate has not been updated pursuant to Paragraph 4.a.(1), above, within one (1) year and is not otherwise available, then Defendant may utilize the most recent update of that specific cost, and adjust that prior cost pursuant to Paragraph 4.a.(2), above, provided that Defendant identifies the specific cost and includes a brief explanation for adjusting the cost pursuant to Paragraph 4.a.(2), above.

10

Mosaic Appendix 2

d.         If providing Financial Assurance under Section III.B (Type B Financial Assurance), in addition to Paragraphs 4.a.-4.c., Defendant shall submit with the initial Cost Estimate and Updated Cost Estimate the calculation and documentation for the average discount rate used for the NPV. In addition, the inflation factor to be used to inflate Long Term Care costs for purposes of deriving the NPV of Long Term Care shall be the mathematical average of the calculated inflation factors for each year over a five (5)-year period. Each year’s calculated inflation factor shall be the product of dividing the GDP Deflator for the relevant year by the GDP Deflator for the year immediately prior, beginning with the first year in which the GDP Deflator is an estimate and for each year thereafter until the fifth year. The Gross Domestic Product (GDP) Deflator is as specified in the “GDP (Chained) Price Index” of theGross Domestic Product Deflators Used in the Historic Tables (Table 10.1), published by the Office of Management and Budget (“OMB”). If the OMB publication is unavailable, in a written agreement not subject to Court approval under Section XVIII (Modification) of the Consent Decree, EPA and Defendant shall identify another method to derive the inflation factor.

e.         Defendant shall submit the Updated Cost Estimate, in accordance with this Paragraph, sixty (60) Days prior to the Anniversary Date of the establishment of the Financial Mechanism, except if otherwise provided herein. If more than one Financial Mechanism is being used to establish Financial Assurance, the Updated Cost Estimate shall be submitted sixty (60) Days prior to the earliest Anniversary Date, for a given calendar year, of a Financial Mechanism. Notwithstanding the foregoing, if Defendant is establishing Financial Assurance pursuant to Paragraph 10.a(1)(c), Defendant shall submit Updated Cost Estimate(s) pursuant to this Paragraph 4.e. as follows: (1) Updated Cost Estimate required pursuant to Paragraph 4.c. by March 31, 2017, and by March 31 every five (5) years thereafter; and (2) Updated Cost Estimate required by Paragraph 4.a. by the end of February in 2018 and in all years thereafter except when the Updated Cost Estimate is provided under 4.e.(1), above.

5.        Notwithstanding the provisions of Section XII (Information Collection and Retention) of the Consent Decree, Defendant shall maintain, or have electronic access to (such that upon request the information can be readily downloaded and printed), at the Facility for the duration of this Consent Decree the Updated Cost Estimate.

III.  Financial Assurance for Phosphogypsum Stack System Closure and Long Term Care

6.        Within thirty (30) Days of the Effective Date of the Consent Decree or within thirty (30) Days of EPA’s approval of Defendant’s initial Cost Estimate, whichever is later, and on the first Anniversary Date and annually thereafter, Defendant’s CFO shall provide to EPA an originally signed CFO Certification, together with supporting documentation, confirming that it has established Financial Assurance for Phosphogypsum Stack System Closure and Long Term Care, in an amount no less than the Total Florida Cost Estimate and pursuant to the requirements of either Section III.A (Type A Financial Assurance) or Section III.B (Type B Financial Assurance), of this Appendix, at Defendant’s election. If Defendant is providing Financial Assurance pursuant to Paragraph 10.a(1)(c), Defendant’s CFO shall provide a CFO Certification in accordance with Paragraph 29.d of this Appendix within fifteen (15) Days after such Financial Assurance has initially been provided.

11

Mosaic Appendix 2

7.        Once Defendant establishes either Section III.A (Type A Financial Assurance) or Section III.B (Type B Financial Assurance) (hereinafter also known as Section III.A or Section III.B, respectively) for Phosphogypsum Stack System Closure and Long Term Care, it shall maintain such Financial Assurance pursuant to the requirements of Section III.A or Section III.B, as applicable, unless EPA approves a request to provide Financial Assurance pursuant to the other Section (i.e., Section III.A or Section III.B, as applicable). If Defendant wishes to request such a change in its Financial Assurance as specified above, then Defendant shall submit to EPA for approval: (a) an originally signed CFO Certification, together with supporting documentation, explaining in detail the reasons for the request; and (b) proposed Financial Assurance, compliant with the applicable Section III.A or Section III.B requirements, that can become effective within thirty (30) Days of EPA’s approval. Defendant shall not cancel its existing Financial Assurance for Phosphogypsum Stack System Closure and Long Term Care until it receives EPA’s written approval of Defendant’s request and the alternate Financial Assurance is in effect (e.g., trust fund is funded; insurance policy is in effect). If Defendant is providing Section III.A (Type A Financial Assurance) pursuant to Paragraph 10.a.(1)(c), a request to substitute another form of Section III.A (Type A Financial Assurance), or substitute Section III.B (Type B Financial Assurance), EPA’s approval of such a request, shall not release the Defendant from its obligation to maintain the existing Florida Phosphogypsum Trust Fund. EPA’s determination whether to approve Defendant’s request to provide alternate Financial Assurance may take into account Defendant’s ability to promptly comply with the requirements of the other of Section III. A or Section III.B, its financial stability, and other such factors and proposals as Defendant may advance in requesting the change.

A.  Type A Financial Assurance

8.        Financial Assurance for Phosphogypsum Stack System Closure and Long Term Care under this Section III.A (Type A Financial Assurance) must comply with the requirements of 40 C.F.R. §§ 264.143(a)-(i), 264.145(a)-(i), 264.148, and 264.151, except as clarified and modified in this Section III.A.

Defendant shall establish Section III.A (Type A Financial Assurance) in an amount at least equal to the Total Florida Cost Estimate.

10.      Defendant shall choose from the Financial Mechanisms specified in 40 C.F.R. §§ 264.143(a)-(f) and 264.145(a)-(f) to establish Section III.A (Type A Financial Assurance), provided that, if Defendant is using Third-Party Mechanisms (a trust fund, letter of credit, surety bond, or insurance), the Trustee of any trust fund, or the provider of any letter of credit, surety bond, or insurance shall not be a Related Party to Defendant. Defendant shall word the Financial Mechanism as specified in 40 C.F.R. § 264.151 unless EPA provides an alternate form, e.g., to address more than one beneficiary of the Financial Mechanism (i.e., EPA and the State) or as otherwise provided by this Appendix.

(5) In addition to the requirements of 40 C.F.R. §§ 264.143(a) and 264.145(a), unless the Defendant is complying with Paragraph 10.a.(1)(c) and thus subject to Paragraph 30.g, below, Defendant shall pay all expenses incurred by the Trustee in connection with the administration of the trust fund, including reasonable fees for legal services rendered to the Trustee, and compensation of the Trustee.

b.         For a surety bond guaranteeing payment or performance, Defendant shall comply with 40 C.F.R. §§ 264.143(b)&(c) and 264.145(b)&(c), except that:

e.         For the corporate financial test, Defendant (including Defendant’s Guarantor), shall comply with 40 C.F.R. §§ 264.143(f) and 264.145(f), except that:

(1) In lieu of complying with 40 C.F.R. §§ 264.143(f)(1)(ii)(A) and 264.145(f)(1)(ii)(A), Defendant shall use the current rating of either Standard & Poor’s (“S&P”) Long-Term Issuer Credit Rating or Moody’s long-term Corporate Family Rating, which assesses a company’s capacity to meet its long-term (greater than one (1) year) financial commitments, as they come due. The rating must be BBB or greater as issued by S&P, or Baa2 or greater as issued by Moody’s. If Defendant has more than one rating, the lower of the two will be used to meet the criteria in 40 C.F.R. §§ 264.143(f) and 264.145(f). If Defendant with multiple ratings discontinues a rating that is below BBB (S&P) or Baa2 (Moody’s), or a rating agency discontinues a rating that is below BBB (S&P) or Baa2 (Moody’s), such that the remaining rating(s) subsequently would enable the Defendant to satisfy the corporate financial test criteria, Defendant shall provide alternate Financial Assurance and shall be disqualified from using the corporate financial test for two (2) years.

(2) The phrase “all Environmental Obligations” is substituted for “current closure and post-closure cost estimates and current plugging and abandonment cost estimates” found in 40 C.F.R. §§ 264.143(f)(1) and 264.145(f)(1).

(3) The term “assets” specified in 40 C.F.R. §§ 264.143(f)(1)(i)(D)&(ii)(D) and 264.145(f)(1)(i)(D)&(ii)(D) shall be replaced by the term “tangible assets.”

Where differences or discrepancies exist between Defendant’s CFO Letter and Defendant’s Independently Audited year-end financial statements, the report of procedures and findings will reconcile any differences or discrepancies between the values or information represented in Defendant’s CFO Letter and Defendant’s Independently Audited financial statements. Procedures to be performed by the independent CPA shall be in accordance with AT Section 201.

(6) Within thirty (30) Days of notice from EPA that EPA, pursuant to 40 C.F.R. §§ 264.143(f)(7) and 264.145(f)(7), no longer believes that Defendant meets the requirements of the corporate financial test criteria of Paragraph 10.e., or that EPA disallows the use of the corporate financial test based on qualifications in the opinion expressed by the independent CPA as set out in 40 C.F.R. §§ 264.143(f)(8) and 264.145(f)(8), Defendant shall establish alternate Financial Assurance as required by 40 C.F.R. §§ 264.143(f)(7)&(8) and 264.145(f)(7)&(8) pursuant to this Section III.A (Type A Financial Assurance). Defendant’s failure to timely establish alternate Financial Assurance is not subject to Section VII (Temporary Non-Compliance) of this Appendix.

(c) On a quarterly basis prepare and use financial statements (including balance sheets, income statements, and cash flow statements), reviewed by an independent CPA, to evaluate Defendant’s ability to meet the criteria of the corporate financial test. To meet the criteria involving rolling averages, the averages shall be based on the results as of the end of the same quarter for the prior years (i.e., a three (3)-year rolling average evaluated at the end of the first quarter for Year X shall include the results from the first quarter of Year X-2 and X-1). In addition, Operating Cash Flow for this evaluation shall be based on the results from the most recent four (4) quarters (i.e., for a first quarter analysis, the Operating Cash Flow shall be based on the results from the second quarter of the previous year through the first quarter of the current year). The same adjustment shall be made for the OCF metric for prior periods if the criteria involve the use of a rolling average.

(d) If Defendant with a S&P rating of BBB- through BB, a Moody’s rating of Baa3 through Ba2, or an equivalent rating from an NRSRO receives a negative outlook posted

23

Mosaic Appendix 2

on one or more of its ratings, or receives a qualified opinion rendered by an independent CPA, Defendant within twenty (20) Days of such event shall submit to EPA a revised corporate financial test based on the most recent evaluation conducted under Paragraph 15.e.(6)(c), above.

f.         For the Corporate Guarantee, Defendant shall comply with 40 C.F.R. §§ 264.143(f)(10) and 264.145(f)(11), and shall meet the requirements specified below, if applicable.

(2) Defendant shall use the exact wording as specified in Form 5-A, Attachment D of this Appendix, for the Corporate Guarantee. The certified copy of the Corporate Guarantee must accompany the items sent to EPA, in accordance with Section XV (Notices) of the Consent Decree, as specified in Paragraph 15.e.(3) of this Appendix.

16.      Defendant may submit annually, for EPA approval, a request to use a letter of credit, surety bond guaranteeing payment, or insurance in lieu of the trust find required under Paragraph 14, above. Defendant shall include in its request documentation demonstrating compliance with Financial Assurance under this Subsection III.B. Defendant may not rely upon the letter of credit, payment surety bond, or insurance to establish compliance with this Appendix until EPA has approved the Third-Party Mechanism. Defendant shall comply with the letter of credit, payment surety bond, or insurance requirements of Paragraph 15 of this Appendix, as applicable. Defendant shall also demonstrate compliance with Paragraph 11 of this Appendix. EPA’s determination whether or not to accept Defendant’s request is subject to dispute resolution pursuant to Section XI (Dispute Resolution) of the Consent Decree, but is not subject to judicial review.

17.      Defendant may submit annually, for EPA approval, a request to use multiple Third-Party Mechanisms (i.e., trust fund, letter of credit, surety bond guaranteeing payment, and insurance) in conjunction with aSelf-Assurance Mechanism, together with supporting documentation, to demonstrate Financial Assurance for Phosphogypsum Stack System Closure and Long Term Care. Defendant shall not rely upon the additional Third-Party Mechanism to establish compliance with this Consent Decree until EPA has approved the additional Third-Party Mechanism. Defendant shall also demonstrate compliance with Paragraph 11 of this Appendix. EPA’s determination whether or not to accept Defendant’s request is subject to dispute resolution under Section XI (Dispute Resolution) of the Consent Decree, but is not subject to judicial review.

18.      If Defendant at any time becomes ineligible to rely on a Self-Assurance Mechanism pursuant to this Section III.B, and cannot re-establish such eligibility pursuant to Section VII (Temporary Non-Compliance) and/or Section VIII.B (Compliance Schedule: Type B) of this Appendix, then Defendant shall establish alternate Financial Assurance based on Current Dollars by: (a) maintaining the existing Financial Assurance in the trust fund (or as approved, other

24

Mosaic Appendix 2

Third-Party Mechanism) as established pursuant to Paragraph 14; (b) providing additional Financial Assurance using Third-Party Mechanism(s) pursuant to Paragraphs 10.a-d, except for Paragraph 10.a.(1)(c); and (c) meeting the requirements of Paragraph 11 of this Appendix when providing more than one Financial Mechanism.

(a) The current configuration of the Phosphogypsum Stack System at the Operating and Closing Facilities, as reflected in Attachment F, Exhibit F-1 (i.e., existing Phosphogypsum Stack System), including any increase in height within that configuration and its current footprint up to its design height, and

(b) Any planned lateral expansion(s) of the existing Phosphogypsum Stack System at the Operating Facilities as identified by the Defendant in 2015 (i.e., Attachment F, Exhibit F-2, and identified in Attachment G: Baseline as “Planned Future Expansion Closure Area”) (“Planned Expansion”): (i) that qualifies as a “Covered Expansion” under Paragraph 29.b.(2) below, and (ii) that becomes part of the Phosphogypsum Stack System

30

    Mosaic Appendix 2

configuration (i.e., fully-engineered and constructed) upon and in accordance with any requisite approvals by FDEP pursuant to the laws and regulations of Florida. Nothing in this Paragraph or in the Consent Decree shall be construed to limit, alter or supersede the permitting and approval authorities of FDEP with respect to the permitting or timing and conditions of the Planned Expansion(s).

(2) The Planned Expansion shall be a Covered Expansion if it meets either of the following criteria, below, to be determined at the time the Planned Expansion(s) is fully engineered and the information required by Paragraph 29.b.(3), below, has been submitted (the “Determination Date”):

(a) The Total Phosphogypsum Volume³ in the Phosphogypsum Stack System anticipated at the Determination Date (calculated pursuant to Paragraph 29.b.(3), below) is not more than two point five percent (2.5%) greater than the Total Phosphogypsum Volume anticipated in 2015 (as specified in the Attachment G: Baseline), and the anticipated Total Future Closure Area at the Determination Date (calculated pursuant to Paragraph 29.b.(3), below) is not more than three percent (3%) greater than the Total Future Closure Area anticipated in 2015 (as specified in Attachment G: Baseline); or

(b) The sum of the following is not more than five percent (5%):

(c) Defendant shall, in making the calculations required by Paragraph 29.b.(2)(b), above, substitute zero (“0”) for a negative percentage that may be generated when comparing the Total Phosphate Volume or the Total Future Closure Area as of the Determination Date to the 2015 baseline.

(3) Defendant shall submit to EPA information regarding the Planned Expansion(s) at the Operating Facilities as follows:

(a) If Defendant has not provided the information regarding the Planned Expansion(s) at the Operating Facilities identified by Defendant in 2015 using the form in Attachment G, prior to the Effective Date of the Consent Decree, then Defendant shall submit such information to EPA (the “Attachment G: Baseline”) within thirty (30) Days of the Effective Date of the Consent Decree to use as a baseline in determining if the Planned Expansion(s) once fully engineered is a Covered Expansion.

(b) Defendant shall submit updated information regarding the Planned Expansion using the form in Attachment G (the “Attachment G: Updated”), within 45 (forty-five) Days of the time that a Planned Expansion has been fully-engineered. The information submitted shall be used to determine if the Planned Expansion as fully engineered is a Covered Expansion. Attachment G: Updated shall include the following adjustments, if applicable:

³ Total Phosphogypsum Volume is utilized herein as an approximate surrogate for pore water volume.

31

    Mosaic Appendix 2

(i) If Defendant has not installed an intermediate liner as identified in the 2015 baseline as reflected in Attachment G: Baseline at the corresponding average stack elevation prior to activation of the Planned Expansion, then the Total Phosphogypsum Volume shall be revised in the Attachment G: Updated to account for the lack of the intermediate liner by adding in the corresponding values of phosphogypsum volume deducted for that anticipated liner as previously calculated and reflected in the Attachment G: Baseline in the column labelled “Phosphogypsum Volume to be Added if Intermediate Liner is Not Installed as Planned (acre-feet).”

(ii) If Defendant has, after 2015, either lined or closed an isolated section of the Phosphogypsum Stack System or has installed an intermediate liner for such section that had not been identified in the 2015 Attachment G, the volume of phosphogypsum beneath the intermediate or other liner at the time of liner installation may be reduced at the rate of eight percent (8%) annually for the period following the installation of the liner until the Determination Date, when calculating the Total Phosphogypsum Volume on the Updated Attachment G.

(iii) If Defendant, after 2015, closes a portion of the stack top area or slope area earlier than scheduled to be closed, the corresponding area(s) may be deducted from the Total Future Closure Area in the Updated Attachment G, provided there are no then-planned lateral or vertical expansions that would require re-activating the closed areas.

(4) Notwithstanding the adjustments in Paragraph 29.b.(3)(b), above, a Planned Expansion shall not be considered a Covered Expansion if the total area of the Planned Expansion as fully engineered exceeds the area of the Planned Expansion as specified in Attachment F (Figure F-2) and the Attachment G: Baseline (i.e., “Future Expansion Closure Area”) by more than eight percent (8%).

(5) Defendant shall provide financial assurance under applicable State law and regulations for:

(a) Any new Phosphogypsum Stack, new Phosphogypsum Stack System, or new expansion of a Phosphogypsum Stack System (i.e., any lateral expansions, increased height above the design height as of 2015, new cooling pond or other form of expansion, in each case to the extent not identified in Attachment F); and

(b) A Planned Expansion that exceeds the criteria for a Covered Expansion. The financial assurance shall be in an amount equal to the difference in the (i) costs of Phosphogypsum Stack System Closure and Long Term Care between the Planned Expansion as anticipated in 2015 (see Attachment G: Baseline, “Planned Future Expansion Closure Area” and “Planned Future Expansion Phosphogypsum Volume”) for the Operating Facility and (ii) the fully-engineered, actual build of the Planned Expansion, as permitted by FDEP, and as reflected in Attachment G: Updated (i.e., “Expansion Closure Area” and “Expansion Phosphogypsum Volume”). This financial assurance, unless otherwise agreed to by FDEP in its sole discretion, is due within ninety (90) Days of submitting the Attachment G: Update.

(6) Defendant shall not use the Financial Mechanisms demonstrating Financial Assurance under this Consent Decree (e.g., Financial Mechanisms specified in Paragraph 29.a. of this Appendix) or that may be required in Paragraphs 27 or 32 of this Appendix, in establishing or

32

    Mosaic Appendix 2

demonstrating compliance with any financial assurance required pursuant to any federal or State law or regulations. Defendant is not precluded from relying on such Financial Mechanisms in satisfying any financial metric or test utilized for financial assurance when permitted under a federal or State law or regulation.

(7) Defendant shall archive and maintain the Computer Aided Design (“CAD”) files, for the Operating Facilities, which contain the underlying information for the values specified in Attachment G: Baseline. Defendant shall maintain the CAD files until Phosphogypsum Stack System Closure and Long Term Care, pursuant to a Permanent Closure Plan, has been implemented at the New Wales Facility. Defendant shall provide access to the CAD files, or provide the CAD files, within thirty (30) Days of the EPA’s request.

c.        Defendant shall first draw upon its own resources or a Guarantor’s resources (as set forth in Paragraph 32), before requesting any reimbursement or release from the Florida Phosphogypsum Trust Fund or any other Third-Party Mechanism established pursuant to this Section VIII to pay for the Phosphogypsum Stack System Closure and/or Long Term Care at the Operating and Closing Facilities. If EPA approves additional Third-Party Mechanisms, as set out in Section III.A (Type A Financial Assurance) of this Appendix (e.g., insurance), EPA will determine the priority for drawing on the Third-Party Mechanisms and such determination is not subject to dispute resolution pursuant to Section XI (Dispute Resolution) of the Consent Decree and is not subject to judicial review.

a.        If Defendant fails to satisfy the corporate financial test criteria and requirements of Paragraph 15.e., above, for each quarter in a given fiscal year (not including the fourth quarter (i.e., fiscal year-end)), except as provided in Paragraph 33.b., below, Defendant shall increase the face value or the corpus of the Third-Party Mechanism by twenty-five percent (25%). If Defendant can satisfy the corporate financial test criteria by the fiscal year-end (i.e., in its annual submission pursuant to Paragraph 15.e.(3), above) and Defendant’s quarterly review under Paragraph 15.e.(6)(b) for the following fiscal year does not result in notification from Defendant that it does not satisfy the corporate financial test, Defendant can request and EPA will authorize the release of funds or a reduction in the value of the Third-Party Mechanism commensurate with the contemporaneous Cost Estimate and requirements of Paragraph 15.e. of this Appendix.

b.        If Defendant fails to satisfy the corporate financial test criteria and requirements of Paragraph 15.e., above, for any two (2) consecutive quarters in a given fiscal year (not including the fourth quarter (i.e., fiscal year-end)), Defendant shall provide alternate Financial Assurance in accordance with Paragraph 18 of this Appendix. If Defendant can satisfy the corporate financial test criteria by the fiscal year-end (i.e., in its annual submission pursuant to Paragraph 15.e.(3)) and its annual submissions pursuant to Paragraph 15.e.(3), above, for the following two (2) fiscal years do not trigger Paragraphs 15.e.(4) or 15.e.(5), above, EPA upon Defendant’s request will authorize a release of the funds or a reduction in the value of the Third-Party Mechanism(s) so that the value of the Third-Party Mechanism is commensurate with the minimum threshold funding for a Third-Party Mechanism as specified in Attachment E plus an additional twenty-five percent (25%) of the Cost Estimate.

c.        Defendant shall be deemed to be without Financial Assurance for purposes of enforcement (but not for accessing or collecting Financial Assurance should it be necessary) if Defendant fails to meet a compliance schedule. Failure to timely comply with a compliance schedule or to provide alternate Financial Assurance pursuant to this Section VIII.B (Compliance Schedule: Type B Financial Assurance) is not subject to the provisions of Section VII (Temporary Non-Compliance) of this Appendix.

IX.Business Transactions

34.      No transfer of ownership or operation of a Facility shall relieve Defendant of its Financial Assurance obligations under this Consent Decree, except as provided by this Section X (Force Majeure) and Section II (Applicability) of the Consent Decree.

35.      At least thirty (30) Days prior to any transfer, Defendant shall submit to EPA information explaining the proposed transfer in detail and stating whether Defendant requests the transfer of its Financial Assurance responsibilities to the Transferee pursuant to Section II (Applicability) of the Consent Decree and Paragraph 36.b, below.

36.      In the event of a transfer of a Facility’s ownership or operation:

a.        If Defendant is to retain its Financial Assurance obligations upon the transfer of the Facility, Defendant, based on a Cost Estimate in Current Dollars, shall establish and fund a trust fund, or obtain a surety bond or letter of credit in accordance with this Appendix. Any existing trust fund established pursuant to Paragraph 10.a.(1)(c) shall remain in place. Defendant shall provide EPA the appropriate documentation evidencing the trust fund, surety bond, or letter of credit by the date of the Facility transfer. If using a trust fund, the portion of funds vested in

43

Mosaic Appendix 2

the trust fund that are not required to meet annual withdrawals shall be invested in U.S. Treasury Bills, or market-based notes and bills that achieve an investment goal or preservation of principle and guarantee an inflation-adjusted rate of return no less than the 30-Year Treasury Constant Maturity Rate average for the previous twelve (12) months from the date of the annual Cost Estimate. If Defendant wishes to propose alternate Financial Mechanism(s) in lieu of the trust fund, surety bond, or letter of credit, Defendant at least thirty (30) Days prior to the transfer shall submit an originally signed CFO Certification from the Defendant’s CFO, together with supporting documentation, explaining the compelling reasons why the proposed alternate Financial Mechanism is being requested and is an equivalent substitute for the trust fund, surety bond, or letter of credit. Upon EPA’s approval, which shall be subject to dispute resolution pursuant to Section XI (Dispute Resolution) of the Consent Decree but shall not be subject to judicial review, Defendant shall establish the approved Financial Assurance. If by the date of the transfer, EPA does not approve such a request or the Defendant has not put in place the approved Financial Assurance, then Defendant shall fully fund the trust fund or obtain a surety bond or letter of credit, as described above.

b.        If Transferee agrees to assume Defendant’s Financial Assurance obligations, Defendant shall submit to EPA for approval an originally signed certification by Transferee’s CFO, together with supporting documentation, explaining in detail its ability to provide Financial Assurance pursuant to the requirements of this Appendix (except for Paragraph 10.a.(1)(c)) and agreeing to provide the Financial Assurance if approved by EPA pursuant to Section II (Applicability) of the Consent Decree. Defendant shall comply with the requirements of Paragraph 36.a., above, until: (1) EPA has approved Transferee’s proposed Financial Assurance; (2) the United States, after consultation with Florida, consents to the transfer of obligations pursuant to Section II (Applicability) of the Consent Decree; (3) Transferee has established the approved Financial Assurance; and (4) EPA has given its consent for Defendant to terminate its Financial Assurance. If Defendant is providing Financial Assurance pursuant to Paragraph 10.a.(1)(c) of this Appendix, and if the Transferee is acquiringall of the Defendant’s Operating and Closing Facilities in Florida, then the Florida Phosphogypsum Trust Fund (see Paragraph 30.b), and if still in existence, the required Guarantee (see Paragraph 32.c) and the required letter of credit, will be the Financial Assurance subject to Paragraph 36.b.(4) that may be terminated.

37.      If Defendant is providing Financial Assurance through the use of any Financial Mechanism other than the exclusive use of a fully funded trust fund in Current Dollars, in the event of a business transaction that results, or Defendant determines will result, in an adverse material change to Defendant’s financial or corporate structure such that Defendant or its successor (or a Guarantor of Defendant or its successor) has insufficient operating cash flow or Tangible Assets to cover the long-term (greater than one (1) year) financial liabilities as represented on the Defendant’s or successor’s audited balance sheet and to comply with the Financial Assurance requirements of this Consent Decree, Defendant shall provide notice to EPA within fourteen (14) Days of identifying such adverse material change and comply with the requirements for Financial Assurance in Paragraph 36.a., above.

38.      If Defendant becomes a private company, Defendant shall provide, in addition to the CFO Letter in Attachment D (Forms 4), a full accounting of its financial condition and a certification from the CFO that the Defendant expects to have sufficient operating cash flow or Tangible Assets located in the United States to cover long-term (greater than one (1) year) financial

44

Mosaic Appendix 2

liabilities as represented in the audited financial statements and to comply with the Financial Assurance requirements of this Consent Decree Defendant shall make such a certification as long as Defendant provides a Self-Assurance Mechanism a part of its Financial Assurance.

X.Reservation of Rights

39.      If EPA determines at any time that the Financial Assurance provided by Defendant no longer satisfies the requirements of this Consent Decree, it shall notify Defendant. EPA may base this determination on Defendant’s failure to provide notices or documentation required by this Appendix as well as on a substantive evaluation of Defendant’s Financial Assurance. Within thirty (30) Days of written notice from EPA that Defendant’s Financial Assurance no longer satisfies the requirements of this Consent Decree, Defendant shall submit to EPA for approval revised or alternate Financial Assurance that satisfies the requirements of this Consent Decree. Defendant shall not cancel the existing Financial Assurance until the revised or alternate Financial Assurance has been approved by EPA and EPA has provided written consent permitting Defendant to cancel the existing Financial Assurance. Failure to timely provide alternative Financial Assurance as required by this Section (or any Paragraph of this Appendix that references this Section) is not subject to the provisions of Section VII of this Appendix. EPA’s determination shall be subject to dispute resolution pursuant to Section XI (Dispute Resolution) of this Consent Decree, but not judicial review, and the time frames for notices and submissions under the dispute resolution process shall be reduced by half (e.g., under Informal Dispute Resolution Defendant shall submit its Notice of Dispute within fifteen (15) Days). In the event that Defendant is providing Financial Assurance pursuant to Paragraph 10.a.(1)(c), and there is a conflict between this Paragraph 39 and Paragraph 32, then the provisions of Paragraph 32 shall control, except that the time frames for notices and submissions under Section XI (Dispute Resolution) of this Consent Decree shall be reduced by half unless otherwise specified in Paragraph 32 of this Appendix.

Appendix 2, Attachment B

to Paragraph 4.c.(2). Requirements under the Consent Decree for Cost Estimate are found in Appendix 2, Section II, of the Consent Decree.

¨ A.             Inflation Adjustment to Cost Estimate

The Cost Estimate may be adjusted for inflation by using an inflation factor. Please follow the instructions below in each subsection to derive the inflation factor that must be used when adjusting the Cost Estimate for inflation. If providing Financial Assurance pursuant to Appendix 2, Subsection III.A, of the Consent Decree, complete subsections A(1)-(2), below. If providing Financial Assurance pursuant to Appendix 2, Subsection III.B of the Consent Decree, complete subsections A(1) & (3), below. Use of an inflation factor may only occur when there is a Phosphogypsum Stack System Closure and Long Term Care Cost Estimate and a periodic re-evaluation of the Cost Estimate is not required under Section II of Appendix 2 (e.g., Paragraph 4.c.).

Inflation Factor

When adjusting for inflation to update the current dollar Cost Estimate in subsection A(1) and A(2), below, the inflation factor must be derived from the most recent Implicit Price Deflator for Gross National Product (“Deflator”) published by the U.S. Department of Commerce in itsSurvey of Current Business.The inflation factor is the result of dividing the latest published annual Deflator by the Deflator in effect at the time of the latest current dollar Cost Estimate. Attachment B, Exhibit 1 provides information (and examples) to use when deriving the imputed deflators for the annual inflationary adjustments under Appendix 2.See also Appendix 2, Paragraphs 4.a.(1) and 4.a.(2), of the Consent Decree. (For additional information and guidance see 40 C.F.R. §§ 264.142(b)(1)&(2) and 264.144(b)(1)&(2).)

Instructions: See also Examples 1 and 2, below.

1. The fiscal quarters for the prior year are listed in Column (A). Thefirstentry in this column is Q1 of the prior year, and thelast entry in this column is Q4 of the prior year.

2. Add thepublished quarterly deflators into Column (B). Do not add any deflators to this column, if they have not yet been published.

3. For each published deflator in Column (B), add the change from the previous quarter in column (C). For example, to calculate the change for Q2, subtract the published deflator value for Q1 from the published deflator value in Q2. Column (C) should include entries only for quarters for which a published deflator is available.

4. The value for Column (D) is calculated as the average of all entries in Column (C). Enter this value once, in the row with the latest published quarterly deflator.

5. Add the value in Column (D) to the latest published quarterly deflator to calculate the following imputed quarterly deflator in Column (E). (The entries in this column will correspond to the quarters for which there are no published quarterly deflators.) To impute quarterly deflators for more than one quarter, continue adding the value in Column (D) to each imputed quarterly deflator to calculate the quarterly deflator for the next year.

Example 1: Imputing a Deflator when Q1 through Q3 Deflators are published, but Q4 Deflator is not

	(A)	(B)	(C)	(D)	(E)
	Quarter	Published Deflator	Change	Average Change	Imputed Deflator

3	Q3 2013	107.044	0.436	0.360
4	Q4 2013				107.404

This example assumes that the latest published quarterly deflator is Q3 2013. The imputed quarterly deflator for Q4 2013 is found in Cell 4E,107.764.

3	Q3 2013				106.892
4	Q4 2013				107.176

This example assumes that the latest published quarterly deflator is Q2 2013. Because there are only two quarters with published deflators in Column (B), the values in Column (C) and Column (D) are the same. The value in Cell D2 is added to Cell B2 to derive the imputed deflator for Q3 2013 (see Cell E3). To derive the imputed deflator for Q4 2013, the value in Cell D2, is added to imputed deflator for Q3 2013 (Cell E3) to derive the imputed deflator for Q4 2013 (Cell E4).

ADJUSTING LONG TERM CARE AND ASSOCIATED WATER MANAGEMENT COSTS TO CALCULATE CURRENT (THEN-YEAR) COSTS

Instructions:

1. Use the information and formulas, below, to determine the current (then-year) dollars for Long Term Care and associated Water Management costs (i.e., columns [C] and [E], below).

2. The Long Term Care and associated Water Management costs in Current Dollars to be used in columns [B] and [D], below, shall be obtained, as appropriate, by calculating the inflation adjusted Long Term Care and associated Water Management costs pursuant to Section II.A(2) of Attachment B or from the information provided in Section II.B(1)(b) of Attachment B.

3. For purposes of determining the inflation factor, the Gross Domestic Product (GDP) Deflator is as specified in the “GDP (Chained) Price Index” of the Gross Domestic Product Deflators Used in the Historic Tables, published by the Office of Management and Budget (“OMB”). The inflation factor used to inflate the costs in this attachment shall be derived from the mathematical average of the calculated inflation factors for each year over a five-year period. Each year’s calculated inflation factor shall be the product of dividing the GDP for the relevant year by the GDP for the year immediately prior, beginning with the first year in which the GDP Deflator is an estimate and for each year thereafter until the fifth year. (See Paragraph 4.d, Appendix 2, of the Consent Decree.)

4. The inflated costs, as calculated in this Attachment B-2, shall be used to calculate the present value for Long Term Care and associated Water Management costs in Attachment B-3 and to provide information in Section II.A(3) and Section II.B(2) of Attachment B. [Note: Each year’s adjusted costs due to inflation as specified in columns [C] and [E], below, shall be placed in the corresponding line items designated by year in columns [B] and [D] in Attachment B-3.]

Attachment C: Instructions

As part of the annual update of the Phosphogypsum Stack System Closure and Long Term Care Cost Estimate, Defendant shall submit Attachment C. The costs represented in Attachment C are in Current Dollars for the year in which the annual submittal is required. When filling out Attachment C, use the information and definition specified below, and provide any assumptions utilized to provide the information. If it is determined that additional columns are required to accurately represent the annual volume of water to be addressed during Phosphogypsum Stack System Closure or Long Term Care, insert such information providing appropriate notes and assumptions for the additional information.

1. Ponded Water Inventory is the annual volume of water to be removed from the cooling pond, the sedimentation ponds on the Phosphogypsum Stack, the return canal and collection ditches, and from other storage or surge ponds, or sumps in excess of ¹⁄₄ acre, that are part of the Phosphogypsum Stack System (such water is also known as “process water inventory”).

2. Water Balance During Closure is the average annual rainfall that is captured in the Phosphogypsum Stack System minus the average annual evaporation from the ponded water surfaces and evapotranspiration from non-ponded surfaces.

3. Drainable Pore Water is the annual volume of water contained within the pores of the phosphogypsum that gravity drains during and after closure of the Phosphogypsum Stack.

4. Infiltration is the annual volume of water that infiltrates into the side slopes of the closed Phosphogypsum Stack.¹

5. Total Annual Water Volume is the summation of Ponded Water Inventory, Water Balance During Closure, Drainable Pore Water, and Infiltration water.

6. Annual Average Removal Rate, in gallons per minute (GPM), is determined by dividing the Total Annual Water Volume by 525,600 minutes per year.

7. Annual Water Removal Cost is the total annual cost in millions of dollars needed for the Total Annual Water Volume to achieve the applicable standards.

8. Planning & Closure Period O&M and Monitoring Costs represent annual program management costs, miscellaneous O&M expenses, surface water monitoring costs, groundwater monitoring costs and piezometer installation costs incurred during the five year closure construction period and one year planning period.

9. Closure Construction Costs represent the annual cost of all materials, labor and equipment to close the phosphogypsum stack system including but not

¹ The area of the side slopes of the Phosphogypsum Stack is the horizontal projection of the grassed slopes. The lined ditches and roads are not included in the slope area.

Mosaic

Appendix 2, Attachment C

limited to: grading and earthwork with soil and phosphogypsum; HDPE liner and associated geosynthetics, cost of clay and mixing if utilized, liner soil cover; side slope drains; toe drains; sumps/pump stations; header pipes; grassing soil and phosphogypsum surfaces; security fence; surface water control; permitting and design services; and construction management, QA/QC, and surveying.

10. Program Management Costs represent the annual costs to manage the facility during the 50-year long-term care period.

11. Long Term Care Operational Costs are based on annual: (a) costs for on-site personnel to conduct maintenance, inspection and care activities during the Long Term Care period with a 5% contingency allowance; (b) surface water and groundwater monitoring and analysis costs; (c), mowing and land surface care costs; (d) contingency repairs (e.g., restoration of eroded areas); and (e) pump operation and maintenance costs (e.g., convey water from seepage collection system to water treatment).

12. Total Water Treatment and Closure Costs represent the sum of the Annual Water Treatment Costs, Planning & Closure Period O&M and Monitoring Costs, Closure Construction Costs, Long Term Care Period Program Management Costs, and Long Term Care Operational Costs.

Whereas, pursuant to the Resource Conservation and Recovery Act (“RCRA”), as amended, 42 U.S.C. §§ 6901 et seq., Mosaic Fertilizer has entered into a Consent Decree with EPA and [insert appropriate State designation] (dated [insert date], Docket No. [insert case information]), to resolve the civil claims asserted by EPA, and [insert appropriate State designation] by establishing certain injunctive relief, including Financial Assurance, under the Consent Decree;¹

Whereas, the Effective Date of the Consent Decree is defined in Section XVI (Effective Date) of the Consent Decree;

Whereas, the Consent Decree requires Mosaic Fertilizer to provide Financial Assurance to EPA and [insert appropriate State designation] to address Phosphogypsum Stack System Closure and Long Term Care, whenever required to do so, at the Operating and/or Closing Facilities;

Whereas, in order to provide a portion of the Financial Assurance required by the Consent Decree, Mosaic Fertilizer has agreed to provide EPA and [insert appropriate State designation] with a Guarantee, issued by the Guarantor, as set forth more fully in this Guarantee, below.

I. Recitals

Now therefore, in consideration of the promises contained herein and for the other good and valuable consideration, the receipt and adequacy of which is hereby acknowledged, the Guarantor agrees to the following:

The planned changes or expansions include dates when construction is currently estimated to begin. These dates are subject to change based on numerous factors, including years for attaining intermediate stack elevations and reaching terminal stack elevations, changes in market conditions, changes in production rates and Mosaic’s business plans, and changes to Mosaic’s long-term operating plans for the Facilities. In any event, activation of the planned changes or expansions will likely occur approximately 2 years after the beginning of construction.
The planned changes or expansions also include Mosaic’s best estimate of the locations, area, and acreage for each planned change or expansion. These estimates are based on Mosaic’s projected long-term operating plans and projected availability of rock sources for each Facility. The acreages for planned expansions are based upon either: (1) the lined area and area of surrounding perimeter containment dikes for lateral expansions beyond the existing phosphogypsum stack system footprint; or (2) lined areas atop existing stack surfaces for lateral expansions contained within the existing phosphogypsum stack system.

These dates are subject to change based on numerous factors, including years for attaining intermediate stack elevations and reaching terminal stack elevations, changes in market conditions, changes in production rates and Mosaic’s business plans, and changes to Mosaic’s long-term operating plans for the Facilities. In any event, activation of the planned changes or expansions will likely occur approximately 2 years after the beginning of construction.
The planned changes or expansions also include Mosaic’s best estimate of the locations, area, and acreage for each planned change or expansion. These estimates are based on Mosaic’s projected long-term operating plans and projected availability of rock sources for each Facility. The acreages for planned expansions are based upon either: (1) the lined area and area of surrounding perimeter containment dikes for lateral expansions beyond the existing phosphogypsum stack system footprint; or (2) lined areas atop existing stack surfaces for lateral expansions contained within the existing phosphogypsum stack system.

CORPORATE GUARANTEE

Instructions: The Corporate Guarantee for Phosphogypsum Stack System Closure and Long Term Care, as specified in Appendix 2 of the Consent Decree, must be worded as follows, except that instructions in brackets are to be replaced with the relevant information, if applicable, and the brackets deleted.

Corporate Guarantee for Phosphogypsum Stack System Closure and Long Term Care

Guarantee made this September 28, 2015 by The Mosaic Company, a business corporation organized under the laws of the State of Delaware, herein referred to as “Guarantor.” This Guarantee is made on behalf of Mosaic Fertilizer, LLC (“Mosaic Fertilizer”) of 3033 Campus Dr., Plymouth, Minnesota 55441, which is our wholly-owned subsidiary, to the United States Environmental Protection Agency (“EPA”) and Florida Department of Environmental Protection (“FDEP”).

Whereas, pursuant to the Resource Conservation and Recovery Act (“RCRA”), as amended, 42 U.S.C. §§ 6901 et seq., Mosaic Fertilizer has entered into a Consent Decree with EPA and FDEP (dated [insert date], Docket No. [insert case information]), to resolve the civil claims asserted by EPA, and FDEP by establishing certain injunctive relief, including Financial Assurance, under the Consent Decree;¹

Whereas, the Effective Date of the Consent Decree is defined in Section XVI (Effective Date) of the Consent Decree;

Whereas, the Consent Decree requires Mosaic Fertilizer to provide Financial Assurance to EPA and FDEP to address Phosphogypsum Stack System Closure and Long Term Care, whenever required to do so, at the Operating and/or Closing Facilities;

Whereas, in order to provide a portion of the Financial Assurance required by the Consent Decree, Mosaic Fertilizer has agreed to provide EPA and FDEP with a Guarantee, issued by the Guarantor, as set forth more fully in this Guarantee, below.

I. Recitals

Now therefore, in consideration of the promises contained herein and for the other good and valuable consideration, the receipt and adequacy of which is hereby acknowledged, the Guarantor agrees to the following:

1. Mosaic Fertilizer owns or operates the Operating and Closing Facilities identified in the Consent Decree covered by this Guarantee:

¹ Unless otherwise defined herein, the capitalized items in this Guarantee, including the preamble and recitals, have the meaning provided in the Consent Decree, including Appendix 1 and Appendix 2.

2. For value received from Mosaic Fertilizer, Guarantor guarantees to EPA and FDEP that, in the event Mosaic Fertilizer fails to perform Phosphogypsum Stack Closure and/or Long Term Care at any or all of the Operating and/or Closing Facilities in accordance with the Initial Phosphogypsum Stack System Closure Plan or Permanent Phosphogypsum Stack System Closure Plan and other terms of the Consent Decree, whenever required to do so, the Guarantor shall do so, or shall establish alternate Financial Assurance in the name of Mosaic Fertilizer in accordance within Section III.A of Appendix 2 (except for Paragraph 10.a.(1)(c)), of the Consent Decree, in an amount at least equal to the Total Florida Cost Estimate less the sum of: (i) the most recent value of the Florida Phosphogypsum Trust Fund established in accordance with Appendix 2 of the Consent Decree and as represented by the Trustee in its most recent valuation statement to Grantor and (ii) the aggregate value of any other Third-Party Mechanism secured to establish Financial Assurance in accordance with Appendix 2 of the Consent Decree (“Florida Financial Assurance Delta”).

3. Guarantor shall comply with the reporting requirements of Paragraph 32.h. of Appendix 2 of the Consent Decree, including an annual Representation and Certification from the Chief Financial Officer of Guarantor stating that Guarantor has the financial resources for the next

Mosaic

Appendix 2, Attachment I

fiscal year to fund the lesser of: (i) $415 million or (ii) the Financial Assurance Delta.

4. In the event that Guarantor determines, at any time for the duration of the Guarantee, for any reason, that: (i) the Guarantor is unable to meet the terms of the Guarantee, including Recital 2; (ii) the Guarantor is unable to provide the Representation and Certification required under Recital 3 of this Guarantee; (iii) the Guarantor becomes aware of any changes in the Total Cost Estimate or the Guarantor’s financial conditions that would invalidate or otherwise be inconsistent with the Representation and Certification; or (iv) the Guarantor becomes aware of any changes in the Total Cost Estimate that would invalidate or otherwise be inconsistent with the Representation and Certification, then Guarantor shall, within five (5) Days of such a determination, provide notice of such determination by certified mail to Mosaic Fertilizer, EPA and FDEP. Such notice shall be admissible in evidence in any litigation and create a presumption that the Guarantor cannot provide the required Representation and Certification, and that the Guarantor cannot perform Phosphogypsum Stack System Closure and/or Long Term Care at the Operating and Closing Facilities or establish alternate Financial Assurance in accordance with Appendix 2 in an amount that is at least equal to the Financial Assurance Delta. The Guarantor may rebut this presumption only by clear and convincing evidence.

5. Any notice provided by Guarantor of Guarantor’s inability to comply with the requirements of this Guarantee, shall include a statement of the value of the guaranteed obligations based on current Updated Cost Estimates, and the amount of financial resources that the Guarantor expects to have available for the next fiscal year either to perform Phosphogypsum Stack System Closure and/or Long Term Care activities at the Operating and Closing Facilities or to provide alternate Financial Assurance.

6. Guarantor agrees that, within thirty (30) Days after providing the notice required by Recitals 4 and 5, or after being notified by Mosaic Fertilizer, EPA, or FDEP of a determination that the Guarantor no longer is able to meet its obligations under Recital 2 of this Guarantee or is disallowed from continuing as a Guarantor as specified in Paragraph 32.k. of Appendix 2 because the independent Certified Public Accountant has issued in the report on examination of the Guarantor’s audited financial statements an adverse opinion or a disclaimer of opinion, or has failed to provide a Representation and Certification as required pursuant to Recital 3 or provided an invalid Representation and Certification, and if Mosaic Fertilizer during that time has not provided alternate Financial Assurance for the Florida Financial Assurance Delta (including written approval by EPA and FDEP), then Guarantor shall provide alternate Financial Assurance in accordance with Section III.A of Appendix 2 (except for Paragraph 10.a.(1)(c)), in the name of Mosaic Fertilizer, in an amount at least equal to the Florida Financial Assurance Delta. In the event that Mosaic Fertilizer invokes dispute resolution, subject to the terms set forth in Appendix 2, of a determination by EPA or FDEP, Guarantor agrees that it shall be bound by the final outcome of the dispute resolution.

7. In the event that Guarantor provides notice under Recital 4, Guarantor shall make financial resources available to Mosaic Fertilizer to meet its obligation under Paragraphs 32.j. and 32.1. of Appendix 2 of the Consent Decree to establish alternate Financial Assurance in accordance with Section III.A of Appendix 2 (except for Paragraph 10.a.(1)(c)), or to return Mosaic Fertilizer to compliance if EPA approves a compliance plan and schedule pursuant to Section VII (Temporary Non-Compliance) of Appendix 2 of the Consent Decree. Acceptance by EPA and

Mosaic

Appendix 2, Attachment I

FDEP of any compliance plan and schedule shall not relieve The Mosaic Company of its obligations under this Corporate Guarantee.

8. In the event that EPA approves a compliance plan and schedule pursuant to Section VII (Temporary Non-Compliance) of Appendix 2 to return Mosaic Fertilizer to compliance with its Financial Assurance obligations under the Consent Decree, and such plan requires the Guarantor to undertake certain activities or provide financial resources, in addition to that specified in Recital 7 above, then Guarantor shall carry out those activities in a timely manner in accordance with the approved compliance plan and schedule.

D. Wastes generated from Downstream Operations only.

Prior to commencement of the GHT or BHT, the wastes from these units may continue to be managed consistent with Mosaic’s consolidated waste management practices submittal dated September 8, 2015. Following the commencement of the operation of the GHT and BHT, if the Downstream wastes are not sent to the GHT or BHT for recovery and reuse, Mosaic shall make a hazardous waste determination of such wastes and manage them in accordance with RCRA. Following the commencement of the operation of the GHT and BHT, downstream scrubber effluent shall not be discharged to the Phosphogypsum Stack System.

II. Background³

Mosaic Bartow’s primary commercial products are the solid ammoniated phosphate fertilizers: monoammonium phosphate (MAP), diammonium phosphate (DAP), and MicroEssentials^® (MES), as well as fluorosilicic acid (FSA). DAP is manufactured in two production trains designated as #3 DAP/MAP and #4 DAP. MAP and MicroEssentials^® are produced in #3 DAP/MAP. Ammonia and phosphoric acid are the primary reactants for MAP, DAP, and MicroEssentials^® and are consumed in the production of ammoniated fertilizers on-site.

Phosphoric acid is produced by the digestion of phosphate rock with sulfuric acid. Mosaic Bartow manufactures phosphoric acid in one production plant with two distinct reactors on-site. The reaction yields phosphoric acid and phosphogypsum (gypsum). Gypsum is filtered from the phosphoric acid on rotating pan filters, slurried with Process Wastewater in gypsum slurry tanks, and the resultant slurry is pumped to a lined Phosphogypsum Stack (gypstack). Because the production of phosphoric acid is a water-intensive process and water is used throughout the process (e.g., as acid dilution water, in the ball mills, evaporators, condensers and as a pipe and tank cleaning agent), approximately 1.6 billion gallons of Process

Wastewater is constantly stored in, and circulating throughout, the facility’s Phosphogypsum Stack System. Mosaic Bartow deposits slurried gypsum in a 60-mil high density polyethylene (HDPE) lined Phosphogypsum Stack located southeast of the facility, south of US Hwy 60. The lined Phosphogypsum Stack operates in conjunction with the existing Phosphogypsum Stack System.

Mosaic Bartow’s Phosphogypsum Stack System is partially lined with 100-mil or 80-mil HDPE. Mosaic Bartow operates the Phosphogypsum Stack System under an Industrial Wastewater Facility Permit issued by the Florida Department of Environmental Protection (FDEP).

III. First Saleable Products at Mosaic Bartow

The line marking the division between Upstream and Downstream Operations lies at the point of generation of the First Saleable Product. Mosaic Bartow generates three first saleable products used as direct feedstocks to MAP, MicroEssentials^® or DAP production:

1) 30% phosphoric acid that is routed to MAP/DAP rather than to further concentration steps

2) 54% clarified phosphoric acid (greater than 1% solids)

3) 54% unclarified phosphoric acid (sludge)

Downstream Operations at Mosaic Bartow are associated with the storage, transport or use of these First Saleable Products in MAP/DAP and MicroEssentials^® operations. Intermediary between the production of 30% acid and the production of 54% clarified acid, Mosaic Bartow recovers fluoride vapors to produce Fluorosilicic Acid (FSA) as a First Saleable Product.

IV. Phosphoric Acid and FSA Production – Phosphoric Acid Plant

Figure 13 identifies Upstream Operations, BHT Recovery Units, Mixed-Use Units, and Grandfathered Units within Mosaic Bartow’s Phosphoric Acid Plant.

Mosaic Bartow’s Phosphoric Acid Plant has approximately 95% impervious surfaces and approximately 20% of the Plant has 40-mil HDPE liner installed below the concrete. Below-grade concrete trenches and pipelines throughout the Plant convey Process Wastewater from the Plant to the Phosphogypsum Stack System at a flow rate of approximately 50,000 – 60,000 GPM. The main Process Wastewater return ditches within the plant are composed of high performance concrete.

A. Standard Acid Flow Configuration

The Phosphoric Acid Plant produces three concentrations of phosphoric acid for use in fertilizer manufacturing: 30% P₂O₅, 40% P₂O₅, and 54% P₂O₅^4,5. The 30% acid that is not used directly as feedstock to fertilizer manufacturing is further processed to 54% P2O5 in Upstream Operations. The standard phosphoric acid manufacturing process described below is illustrated in process flow diagram (Figure 2). Deviations from the standard acid flow configuration are necessary on periodic short-term intervals.

Mosaic Bartow produces phosphoric acid in two reactors designated as the Phosphoric acid Reactor V-Train (“Attack Tank V-Train”) and the Phosphoric acid Reactor U-Train (“Attack

⁴ Note that although the terms P2O5 and phosphoric acid (H3PO4) are used interchangeably, the concentrations are not interchangeable. Mosaic manufactures phosphoric acid, however, in this document we refer to the concentration of the acid in terms of P2O5 concentration, rather than phosphoric acid concentration. P2O5 concentration can be converted to an approximate concentration of phosphoric acid by multiplying by 1.3808. Phosphoric acid is converted to an approximate concentration of P2O5 by multiplying by 0.7242.

⁵ All phosphoric acid concentrations are approximate and fluctuate slightly.

Tank U-Train”). The acid from both reactors mixes at the 30% Clarifier Feed Storage Tank “C” (“30C Tank”- C3T30C) and the 30% Clarifier Feed Storage Tank “D” (“30D Tank”- C3T30D). Prior to mixing at the 30C Tank (C3T30C) and 30D Tank (C3T30D), the acid flows as follows:

Phosphoric acid Reactor V-Train (Upstream Operations): Post-reactor, unclarified 30% acid is pumped to the #1 Filtrate Tank of #3 Filter and then either to the 30C Tank (C3T30C) or the 30D Tank (C3T30D);

Phosphoric acid Reactor U-Train (Upstream Operations): Post-reactor, unclarified 30% acid is pumped to the #1 Filtrate Tank of either #4 or #5 Filter and then either to the 30C Tank (C3T30C) or the 30D Tank (C3T30D);

1) 30% Acid Processed to 30% Clarification (Upstream Operations)

● 30% acid from the 30C Tank (C3T30C) and the 30D Tank (C3T30D) is pumped to either the 30% Clarifier Tank “A” (“31A Clarifier” - C3T31A), 30% Clarifier Tank “B” (“31B Clarifier”- C3T31B), 30% Clarifier Tank “C” (“31C Clarifier”- C3T31C), or 30% Clarifier Tank “D” (“31D Clarifier”- C3T31D);

The locations of the transfer lines are illustrated in Figure 7. The estimated line lengths and cleaning frequencies are listed in Table 5.

D. Fluorosilicic Acid (FSA) Standard Process Configuration

Mosaic Bartow recovers fluoride vapors from Second Stage Evaporator # 5. The recovery of fluoride vapors produces FSA. A generic depiction of the FSA production process is illustrated in Diagram 1.

The Second Stage Evaporator #5 has a FSA production unit, also called a “Swift Tower,” integrated with a barometric condenser. The Swift Tower receives gas emitted from the concentration of 43% P2O5 to 54% P2O5 through evaporation. The gas is condensed in the Swift Tower and the liquid is continuously recirculated through a seal tank and back through the Swift Tower to maintain the seal and operation of the FSA Swift Tower.

17

Mosaic Bartow

Facility Report

FSA is not always produced. When FSA is not being produced for sale or for use as a cleaning solution, the gases pass through the Swift Tower to the barometric condenser, there is no recirculation of FSA through the Swift Tower, and therefore FSA is not produced. Even when FSA is not being produced, the FSA Seal Tank remains an essential part of the Phosphoric Acid Evaporator by sealing the Swift Tower downleg.

When FSA is being produced for sale or for use as a cleaning solution, recirculated liquid will continue to absorb fluoride vapors until the desired strength of FSA is obtained. FSA for sale is a solution of approximately 23-26% strength and specific gravity of 1.20 -1.23.

Once the FSA reaches the desired strength for sale, a slip stream from the recirculation line between the FSA Seal Tank and FSA Swift Tower is sent to the FSA Day Tank (C4T81). In the FSA Day Tank (C4T81), the solution is isolated and tested for meeting customer specifications. Solutions meeting customer specifications in the FSA Day Tank (C4T81) are transferred to the FSA Storage Tank (C4T80) and sold to customers off-site.

If the solution does not meet the minimum customer specifications, within 90 days of that determination, the contents from the FSA Day Tank (C4T81) must be:

1. Returned to the 42 Tank (C4T42) for reprocessing and recovery of acid value when FSA is being produced for sale and/or internal consumption; or

2. Returned to the 40% Clarifier Feed Tank (C4T40) for reprocessing and recovery of acid value when FSA is being produced for sale and/or internal consumption; or

3. Sent to the Phosphoric acid reactors for reprocessing and recovery of acid values, or;

4. Discharged to the Phosphogypsum Stack System, if in compliance with the land disposal restriction (LDR) standards set forth in 40 C.F.R. Part 268, Subpart D, or;

5. Following commencement of operation of the BHT:

a. Sent to the Big Holding Tank, as described in Section VI (Compliance Projects) of this Report, for reprocessing and recovery of acid values; or

b. Used as FSACS and then sent to the Big Holding Tank, as described in Section VI (Compliance Projects) of this Report, for reprocessing and recovery of acid values.

Because sampling cannot take place instantaneously, it may be also necessary at times for FSA, including FSA that does not meet minimum customer specifications, to enter the FSA Storage Tank (C4T80) before sampling results are obtained and/or a customer for this FSA is found. If Mosaic fails to find a customer for the contents of the FSA Storage Tank (C4T80) within ninety (90) days, the contents shall be handled in compliance with the RCRA Subtitle C program.

At any given time prior to the 90 day storage limit, the contents of the FSA Storage Tank (C4T80) may be:

1. Returned to the 42 Tank (C4T42) for reprocessing and recovery of acid value when FSA is being recovered for sale and/or internal consumption; or

2. Returned to the 40% Clarifier Feed Tank (C4T40) for reprocessing and recovery of acid value when FSA is being recovered for sale and/or internal consumption; or

3. Sent to the Phosphoric acid reactors for reprocessing and recovery of acid values; or

4. Discharged to the Phosphogypsum Stack System, if in compliance with the land disposal restriction (LDR) standards set forth in 40 C.F.R. Part 268, Subpart D; or

5. Following commencement of operations of the BHT:

a. Sent to the Big Holding Tank as described in Section VI (Compliance Projects) of this Report, for reprocessing and recovery of acid values, or,

b. Used as FSACS and then sent to the Big Holding Tank, as described in Section VI (Compliance Projects) of this Report for reprocessing and recovery of acid values.

Prior to commencement of operations of the BHT, FSA produced for use as a cleaning solution may continue to be managed consistent with Mosaic’s consolidated waste management practices submittal dated September 8, 2015. Following commencement of operations of the BHT, FSA produced for use as a cleaning solution may be used and then must be sent to the Big Holding Tank, as described in Section VI (Compliance Projects) of this Report, for reprocessing and recovery of acid values.

Mosaic Bartow has one primary transfer line, FSA Shipping Line that serves to transport FSA between the FSA Storage Tank and Truck Loading. The location of the transfer line is illustrated in Figure 5. The line designation and cleaning frequency is listed in Table 3.

E. Ammoniated Process Wastewater Transfer (BHT Recovery Units)

Bartow uses ammonia to pH adjust Process Wastewater before it is sent to the rock grinding circuit. The neutralization process happens in the Pond Water Neutralization Tank located within the footprint of the #3 DAP/MAP (Figure 8). The pH-adjusted Process Wastewater is then sent to the rock grinding area for the processing of phosphate rock and P2O5 recovery from Process Wastewater.

Projects 3, 4, and 5 are projects related to the Downstream Operations in Granulation and recovery of material in the granulation process.

A. BHT and Cleaning Solution Return Piping Projects

1. Project Descriptions

Project 1: Big Holding Tank and Wash Solution System in the Phosphoric Acid Plant

The Big Holding Tank and wash solution system (together designated the “BHT system”) project in the Phosphoric Acid Plant shall install new tank(s) piping, and controls to enable Mosaic to recover the value of wastes, as specified in Section VI.A.2 (Project Operations) below.

Mosaic will refurbish Reuse Water Tank (Figure 13) to serve as an interchangeable backup tank for the BHT system, which may be used in services other than BHT when not operating as a BHT (which other use shall not alter or nullify the status of the backup tank as a BHT Recovery Unit or preclude its use as a part of Upstream Operations, if appropriate). The backup tank will be used during cleaning and/or maintenance of the BHT tank. Cleaning waste from the BHT backup tank will be handled in the same way as the cleaning waste from the BHT itself as described in Section 2. Phosphoric Acid Plant Cleaning Procedures of the BMP.

In addition, new or upgraded pumps, motors, small pump tanks, and instrumentation may be needed to ensure the return to the BHT cleaning wastes and spills and leaks of: (1) phosphoric acid, sulfuric acid, FSA, SACS, PACS, FSACS, or BHT Effluent; or (2) NHACS, Process Wastewater, or Phosphogypsum Stack System Wastewater when mixed with any of the preceding solutions due to spills, leaks, or cleaning of leaks and spills. Project 1 necessarily coincides with Project 2 below.

Project 2: Cleaning Solution Return Piping

Mosaic will install new piping to enable Mosaic to: (1) clean phosphoric acid transfer lines from the Phosphoric Acid Plant to the #3 DAP/MAP and #4 DAP Granulation Plants and return those cleaning wastes to the BHT; (2) clean BHT Recovery Units located in the Granulation Plants and return those wastes to the BHT; and (3) clean FSA system and return wastes to the BHT.

2. Project Operations

The wash solution system will be comprised of the BHT and the SACS make up tank(s), along with pumps and piping to supply cleaning solution to units that are part of Upstream Operations or are identified as Mixed-Use, Grandfathered, or BHT Recovery Units.

Phosphogypsum Stack System Wastewater, Process Wastewater, fresh water, condensate or other water sources will be mixed with sulfuric acid, FSA, phosphoric acid or BHT Effluent in the SACS wash make up tank(s) or BHT. The equipment and lines that are part of Upstream Operations or are identified as Mixed-Use, Grandfathered, or BHT Recovery Units may be washed with SACS either from the BHT or the SACS wash make up tank and the solutions may be returned to the BHT.

In addition, the BHT will enable Mosaic to recover the value of wastes generated from the use of SACS, FSA, FSACS, PACS, Non-Hazardous Aqueous Cleaning Solution, Process Wastewater, Phosphogypsum Stack System Wastewater, BHT Effluent from pipes, tanks, process equipment, or other storage or transport units that: (i) are part of Upstream Operations, (ii) serve to manage, store, or transport Bevill-Exempt Wastes; or (iii) are identified as Mixed-Use, Grandfathered Units, or BHT Recovery Units in this Report. In accordance with the BMP, the BHT will also enable Mosaic to recover spills and leaks in Containable Impervious Areas described in Section VII (Containment of Phosphoric Acid Product Leaks and Spills) of this Report. The BHT may also receive transfers from the GHT in accordance with Section VI. B.2. Project Operations.

The BHT shall in turn return the recoverable streams into Upstream Operations where their values are recovered or managed through the following: (See Figure 1: BHT Inputs and Effluents)

a. as an intermediate wash on the filter, prior to the final cake wash, to inhibit scale formation. This wash ultimately circulates back to the reactor (attack tank); and/or

b. as direct make up to the phosphoric acid reactors; and/or

c. neutralized in the Pond Water Neutralization System (see Section IV.E

Ammoniated Process Wastewater Transfer (BHT Recovery Units)) above and then added to the rock grinding circuit where it will ultimately end up in the slurry fed into the phosphoric acid reactors; and/or

B. GHT Related Projects

1. Project Descriptions

Project 3: Granulation Plant Re-Slurry System (#3 DAP⁷)

Mosaic will install product recovery tank, hopper, piping, steam feed, valves, agitator, and pumps to recover wet fertilizer product. The resulting slurry will be fed to the acid scrubber system for consumption in the granulation process.

Project 4: Granular Holding Tank and Wash Solution System in the Granulation Plant

Mosaic will install two Granular Holding Tank (GHT)⁸ systems- one in #3 DAP/MAP plant and the other in #4 DAP plant. The GHT plus piping, pumps, and instrumentation (together the “GHT system”) will transport and recirculate wash solution between GHT Recovery Units and the GHT and consume the wash solution in the granulation plants (#3 DAP/MAP and #4 DAP) as specified in Section VI.B.2 below.

Project 5: Upgrade Granulation Plants’ Pads and Sumps

Mosaic will modify or install, as needed, containment pads and sumps in each granulation plant to improve the capture of spills, leaks, and cleaning solutions so materials may be returned to the granulation process via the GHT. This will include the #3 DAP/MAP Tank Farm and the #4 DAP Tank Farm as identified in this Report.

2. Project Operations

⁷ DAP4 already has an operational re-slurry system.

⁸ Although Mosaic plans to install more than one GHT, for simplicity this Report will use the singular “GHT” to describe any and all GHTs that will be installed at Mosaic’s Bartow facility.

29

Mosaic Bartow

Facility Report

The GHT system will enable Mosaic to recover the value of wastes generated from the use of SACS, PACS, Non-Hazardous Aqueous Cleaning Solution, Process Wastewater, Phosphogypsum Stack System Wastewater, or GHT Effluent from pipes, tanks, process equipment, or other storage or transport units identified as GHT Recovery Units or manage those wastes as described in Section 3. Granulation Plants Cleaning Procedures of the BMP. In accordance with the BMP, the GHT will also enable Mosaic to recover spills and leaks in Containable Impervious Areas described in Section VII of this report.

A. The GHT shall in turn reuse or recover the recoverable streams as follows:

a. consumed in the acid scrubber system for consumption in the granulation process; and/or

b. consumed directly into the granulation reactor; and/or

c. added to the re-slurry system; and/or

d. recirculated to clean GHT Recovery Units.

B. In GHT cleaning situations identified in Section 3 Granulation Plants Cleaning Procedures - GHT Recovery Units, of the BMP, Mosaic may transfer the contents of the GHT to the BHT if they are RCRA non-hazardous. If the contents of the GHT are hazardous only for the RCRA corrosivity characteristic (pH£ 2), Mosaic may transfer the contents to the BHT no more than two times per calendar year. The GHT shall then be washed with a cleaning solution (SACS, PACS, Process Wastewater, Phosphogypsum Stack System Wastewater, or NHACS). If the wash solution is hazardous only for RCRA corrosivity (pH£ 2), it may be transferred to the BHT not more than two times per calendar year. If the solution is non-hazardous, it can be transferred to the BHT or sent to the Phosphogypsum Stack System.

C. In addition to GHT cleaning situations in B, in non-routine situations (such as mechanical failure in the Granulation Plant, unexpected plant outages, electrical power failures, hurricanes or similar weather events or unexpected problems during startups) and if the GHT is (or imminently will be) at or above 90% (full), Mosaic may transfer GHT Effluent if non-hazardous or hazardous only for the RCRA corrosivity characteristic (pH£ 2) to the BHT, in order to create additional capacity in the GHT, until the GHT’s capacity is at 50%, provided that Mosaic:

i) Manages use of the GHT to BHT transfer line by locking the valve on the transfer line or a system interlock requiring a code to activate;

ii) Obtains approval from its area manager to make the transfer; and

iii) Includes information on each transfer in its reports to the EPA and FDEP as required in Paragraph 41 of the CD.

If Mosaic chooses not to reuse or recover the GHT Effluent as described above, the GHT Effluent must instead be managed in accordance with RCRA.

VII. Containment of Phosphoric Acid Product Spills and Leaks

Any impervious⁹ manufacturing or storage areas not identified in this section as Containable Impervious Areas are considered to be Non-Segregable Areas.

Non-Segregable Areas

Approximately 20% of Mosaic Bartow’s Phosphoric Acid Plant’s impervious surfaces have 40-mil HDPE liner installed beneath them. In several areas, the concrete pad is sloped towards concrete-lined trenches (denoted by orange lines in Figure 10) that transport any leaks and spills to the Phosphogypsum Stack System. Process Wastewater flows through the trenches at a rate of approximately 50,000 – 60,000 GPM to the Phosphogypsum Stack system. Due to the engineered slope of the concrete pad in these areas and the configuration of the Phosphoric Acid Plant, small spills and leaks of phosphoric acid, sulfuric acid, and FSA onto the concrete pad cannot be segregated (“non-segregable areas”) and are mixed in the trenches with the Process Wastewater flowing to the Phosphogypsum Stack system and managed pursuant to Appendix 5, BMP. Mosaic may manage small spills and leaks of phosphoric acid, sulfuric acid, and FSA within the concrete areas of the Phosphoric Acid plant (delineated by redlines in Figure 10) in accordance with the BMP.

⁹ Note, the use of the term “impervious” in this section does not refer to a particular definition of impervious or a particular leakage rate, but instead is used to mean a surface barrier to penetration, such as concrete, liners, steel, epoxy, etc. The term impervious in this section does not include gravel or soil.

The foregoing shall not relieve Mosaic of its obligations under any applicable law.

Other Areas

Any leak or spill of a hazardous material, including phosphoric acid and sulfuric acid, that is not contained within the Containable Impervious Areas or Non-Segregable Areas of the plant shall be managed in accordance with the BMP. The foregoing shall not relieve Mosaic of its obligations under any applicable law.

VIII. Process Water (Wastewater) Treatment Plant (Reverse Osmosis Plant)

Mosaic has installed a reverse osmosis plant at the Bartow facility to reduce Process Wastewater inventory (Diagram 1: Reverse Osmosis Unit Block Flow). The system consumes Process Wastewater and produces a permeate water of sufficient quality to be either discharged through a National Pollutant Discharge Elimination System (NPDES) permitted outfall or used as a fresh water source for the facility. The reject water, concentrated Process Wastewater, is returned to the Phosphogypsum Stack System.

The reverse osmosis plant has several stages of treatment to produce the final permeate. A description of these stages follows.

1) First Stage: Process Wastewater is pumped to any of five Ultra Filtration (UF) trains. UF concentrate flows to the Phosphogypsum Stack System. UF permeate feeds the UF permeate tank (T20.001) or is used to back flush UF membranes and is returned to the Phosphogypsum Stack System.

32

Mosaic Bartow

Facility Report

2) Second Stage: 1^st Stage permeate from the 1^st Stage permeate tank (T20.001) is pumped to any of five 2^nd Stage trains. 2^nd Stage concentrate flows to the Phosphogypsum Stack System. 2^nd Stage permeate feeds the 2^nd Stage permeate tank (T30.001).

3) Third Stage: 2^nd Stage permeate from the 2^nd Stage permeate tank (T30.001) is pumped to any of five 3^rd Stage trains. 3^rd Stage concentrate flows to either the Phosphogypsum Stack System or the 1^st Stage permeate tank (T20.001). 3^rd Stage permeate feeds the 3^rd Stage permeate tank (T40.001).

4) Fourth Stage: 3^rd Stage permeate from the 3^rd Stage permeate tank (T40.001) is pumped to any of five 4^th Stage trains. 4^th Stage concentrate flows to the Clean in Place (CIP) water tank (T70.001). 4^th Stage permeate flows primarily to the product water tank (T50.001). 4^th Stage permeate is pumped from the product water tank (T50.001) to the main gate or returned to the plant to offset fresh water. 4^th Stage permeate feeds a minimal amount to the caustic dilution tank (T92.002). 4^th Stage permeate is tested online for pH and conductivity. If 4^th Stage permeate is out of spec, it is recycled or diverted to the rainwater collection tank (T06.200) so it can be pH adjusted, if needed then released to the Phosphogypsum Stack System.

Cleaning Solutions: Acid and caustic cleaning solutions are circulated through each of the units as needed to CIP. Acid cleaning solution is also back flushed through the first stage membranes for Enhanced Back Flush (EBF). The sulfuric acid solution concentration is typically 1% or less. After circulation the solutions are drained to the spent CIP neutralization tank (T06.100), where the pH is adjusted (>2.0 or <12.5) before being released to the Phosphogypsum Stack System.

Wastes generated from Mosaic Bartow’s reverse osmosis plant shall be managed pursuant to Paragraph 18(a) of the Consent Decree. Mosaic may change the manner in which Mosaic’s Bartow reverse osmosis plant operates without requiring prior approval by FDEP or EPA, provided that Mosaic (i) continues to manage such wastes pursuant to Paragraph 18(a) of the Consent Decree; and (ii) notifies FDEP or EPA of such changes within 90 Days of implementing such changes. In any event, cleaning solutions and filters must be managed in accordance with RCRA.

If GHT Effluent is not reused or transferred to the BHT in accordance with Section VI. Compliance Projects of this Report. Mosaic shall manage GHT Effluent as described in Section 6. Cleaning Solution System Operation of the BMP. The GHT itself is designated a GHT Recovery Unit, and therefore for wastes generated from cleaning the GHT itself, see C.1 above.

3. Process Upset. In the event of a process upset that prevents the recovery of cleaning solutions via the GHT, then Mosaic shall make a hazardous waste determination of cleaning wastes generated from those units affected by the process upset and manage them in accordance with RCRA.

D. Wastes generated from Downstream Operations only.

Prior to commencement of the GHT or BHT, the wastes from these units may continue to be managed consistent with Mosaic’s consolidated waste management practices submittal dated September 8, 2015. Following the commencement of the operation of the GHT and BHT, if the Downstream wastes are not sent to the GHT or BHT for recovery and reuse, Mosaic shall make a hazardous waste determination of such wastes and manage them in accordance with RCRA. Following the commencement of the operation of the GHT and BHT, downstream scrubber effluent shall not be discharged to the Phosphogypsum Stack System.

II. Background³

Mosaic New Wales’s primary commercial products are solid ammoniated phosphate fertilizers monoammonium phosphate (MAP), diammonium phosphate (DAP), and MicroEssentials^® (MES) and the non-ammoniated animal feed ingredients monocalcium phosphate (Biofos^®), dicalcium phosphate (Dynafos^®), sodium calcium phosphate (Nexfos^®). DAP is manufactured in three production trains designated as #1 DAP/MAP and #2 DAP (#2 DAP East and #2 DAP West). MAP is also produced in #1 DAP/MAP, as well as plants designated as #3 granular MAP (GMAP) and powdered MAP (PMAP). Ammonia and phosphoric acid are the primary reactants for MAP and DAP and are consumed in the production of these fertilizers on-site. Animal feed ingredients are manufactured in the AFIP area.

Phosphoric acid is produced by the digestion of phosphate rock with sulfuric acid. Mosaic manufactures phosphoric acid in one production plant with three distinct reactors on-site. The reaction yields phosphoric acid and phosphogypsum (gypsum). Gypsum is filtered from the phosphoric acid on rotating pan filters, slurried with Process Wastewater in Gypsum Slurry Tanks,

³ This Background Section is provided solely for informative purposes and is not a definitive or exhaustive description of the Facility or its operations.

10

Mosaic New Wales

Facility Report

and the resultant slurry is pumped to a lined Phosphogypsum Stack (gypstack). Because the production of phosphoric acid is a water-intensive process and water is used throughout the process (e.g., as acid dilution water, in the ball mills, evaporators, condensers, and as a pipe and tank cleaning agent), approximately 2.5 billion gallons of Process Wastewater is constantly stored in and circulating throughout the facility’s Phosphogypsum Stack System.

Mosaic deposits slurried gypsum in a 60-mil high density polyethylene (HDPE) lined Phosphogypsum Stack located southeast of the facility. The lined South Gypsum Stack operates in conjunction with the existing Phosphogypsum Stack System.

Mosaic’s New Wales Phosphogypsum Stack System is partially lined with 60-mil HDPE (within Lined Emergency Surge Pond-1 (LESP-1) and Lined Emergency Surge Pond-2 (LESP-2)). The pond system consists of the main cooling pond and connecting North, East, and West cooling channels, unlined Auxiliary Holding Pond (AHP), LESP-1 and LESP-2 and Northeast sump located directly east and south of the production complex. Mosaic operates the Phosphogypsum Stack System under an Industrial Wastewater Facility Permit issued by the Florida Department of Environmental Protection (FDEP).

III. First Saleable Products at Mosaic New Wales

The line marking the division between Upstream and Downstream Operations lies at the point of generation of the First Saleable Product. The following are the First Saleable Products at Mosaic New Wales:

1. 30% acid, when fed to #1DAP/MAP, #2 DAP, #3 GMAP, or any other Downstream Operation;

2. 54% acid (greater than 1% solids), when fed to #1DAP/MAP, #2 DAP, #3 GMAP, transported off-site or used in any other Downstream Operation; and

3. 54% Merchant Grade Acid (less than 1% solids) or any greater concentration of acid not associated with non-ammoniated Animal Feed Ingredient Production (AFIP).

Downstream Operations at Mosaic New Wales are associated with the storage, transport or use of these First Saleable Products in MAP, DAP and MicroEssentials® operations. Other First Saleable Products that are part of Upstream Operations are the non-ammoniated animal feed ingredients monocalcium phosphate (Biofos^®), dicalcium phosphate (Dynafos^®) and sodium calcium phosphate (Nexfos^®).

IV. Phosphoric Acid Production – Phosphoric Acid Plant

Figure 11identifies Upstream Operations, Mixed-Use Units and BHT Recovery Units within Mosaic New Wales’ Phosphoric Acid Plant. Figure 2 identifies AFIP Units within Mosaic New Wales’ AFIP Plant.

Mosaic New Wales Phosphoric Acid Plant has approximately 80% impervious surfaces. Below-grade concrete ditches throughout the Plant convey Process Wastewater from the Plant to the Phosphogypsum Stack System at a flow rate of approximately 86,000 GPM. The main Process Wastewater return ditches within the plant are composed of high performance concrete.

A. Standard Acid Flow Configuration

The Phosphoric Acid Plant produces three concentrations of phosphoric acid for use in fertilizing manufacturing – 30% P₂O₅⁴, 40% P₂O⁵, and 54% P₂O₅⁵. The 30% acid that is not used directly as feedstock to fertilizer manufacturing is further processed to 54% P₂O₅ in Upstream Operations. The standard phosphoric acid manufacturing process described below is illustrated in a process flow diagram Figure 1. Deviations from the standard acid flow configuration are necessary on periodic short-term intervals.

Mosaic New Wales produces phosphoric acid in three reactors designated as the Phosphoric acid Reactor East-Train (0048), the Phosphoric acid Reactor West-Train (0049), and the Phosphoric acid Reactor Third-Train (0051). Approximately 70% of the acid from all reactors mixes at the 30% Clarifier Feed Storage Tank “East” (“30East Tank” or “30E Tank” - 0061) and the 30% Clarifier Feed Storage Tank “West” (“30West Tank” or “30W Tank” - 0062). The remaining 30% is sent directly to the following three evaporator feed tanks: 30% Evaporator Feed Tank “East” (“30East Evap Feed Tank” - 0025), 30% Evaporator Feed Tank “West” (“30West Evap Feed Tank” - 0024), and 30% Evaporator Feed Tank “Third” (“30Third Evap Feed Tank” - 0069). Prior to mixing at the 30East Tank (0061) and 30West Tank (0062), the acid flows as follows:

Phosphoric acid Reactor East-Train (Upstream):

Post-reactor, the approximate 30% phosphoric acid slurry is pumped to the East Tilting Pan Filter where gypsum solids are filtered from the phosphoric acid. Gypsum is pumped to the South Gypsum Stack and the unclarified 30% phosphoric acid filtrate flows into the East Filter Filtrate Seal Tank. From the East Filter Filtrate Seal Tank, the 30% unclarified acid is pumped to any of the following tanks: 30E Tank (0061), 30W Tank (0062), 30East Evap Feed Tank (0025), 30West Evap Feed Tank (0024) or 30Third Evap Feed Tank (0069);

Phosphoric acid Reactor West-Train (Upstream):

Post-reactor, the approximate 30% phosphoric acid slurry is pumped to the West Tilting Pan Filter where gypsum solids are filtered from the phosphoric acid. Gypsum is pumped to the South Gypsum Stack and the unclarified 30% phosphoric acid filtrate flows into the West Filter Filtrate Seal Tank. From the West Filter Seal Tank, the unclarified 30% acid is pumped to any of the following tanks: the 30E Tank (0061), the 30W Tank (0062), 30East Evap Feed Tank (0025), 30West Evap Feed Tank (0024) or 30Third Evap Feed Tank (0069);

Phosphoric acid Reactor Third-Train (Upstream):

Post-reactor, the approximate 30% phosphoric acid slurry is pumped to the Third Tilting Pan Filter where gypsum solids are filtered from the phosphoric acid. Gypsum is pumped to the South Gypsum Stack and the unclarified 30% phosphoric acid filtrate flows into the Third Filter Filtrate Seal Tank. From the Third Filter Filtrate Seal Tank the unclarified 30% acid is pumped to any of the following tanks: the 30E Tank (0061), the 30W Tank (0062), 30East Evap Feed Tank (0025), 30West Evap Feed Tank (0024), or 30Third Evap Feed Tank (0069).

⁴ All P₂O₅ concentrations are approximate and fluctuate slightly.

⁵ Note that although the terms P₂O₅ and phosphoric acid (H₃PO₄ ) are used interchangeably, the concentrations are not interchangeable. Mosaic manufactures phosphoric acid, however, in this document we refer to the concentration of the acid in terms of P₂O₅ concentration, rather than phosphoric acid concentration. P₂O₅ concentration can be converted to an approximate concentration of phosphoric acid by multiplying by 1.3808. Phosphoric acid is converted to an approximate concentration of P₂O₅ by multiplying by 0.7242.

One of the tanks may be used in services other than BHT when not operating as a BHT (which other use shall not alter or nullify the status of the backup tank as a BHT Recovery Unit or preclude its use as a part of Upstream Operations, if appropriate). The BHT backup tank will be used during cleaning and/or maintenance of the BHT tank. Cleaning waste from the BHT backup tank will be handled in the same way as the cleaning waste from the BHT itself as described in Section 2. Phosphoric Acid Plant Cleaning Procedures of the BMP.

In addition, new or upgraded pumps, motors, small pump tanks, and instrumentation may be needed to ensure the return to the BHT cleaning wastes and spills and leaks of: (1) phosphoric acid, sulfuric acid, SACS, PACS, or BHT Effluent; and (2) NHACS, Process Wastewater, or Phosphogypsum Stack System Wastewater when mixed with any of the preceding solutions due to spills, leaks, or cleaning of leaks and spills. Project 1 necessarily coincides with Project 2 below.

Project 2: Cleaning Solution Return Piping

Mosaic will install new piping to enable Mosaic to: (1) clean phosphoric acid transfer lines from the Phosphoric Acid Plant to the 1 DAP/MAP, #2 DAP and #3 GMAP Granulation Plants and return those cleaning wastes to the BHT; and (2) clean BHT Recovery Units located in the Granulation Plants and return those wastes to the BHT.

2. Project Operations

The wash solution system will be comprised of the BHT and the SACS make up tank(s), along with pumps and piping to supply cleaning solution to units that are part of Upstream Operations or AFIP, or identified as Mixed-Use, Grandfathered, or BHT Recovery Units.

Phosphogypsum Stack System Wastewater, Process Wastewater, fresh water, condensate or other water sources will be mixed with sulfuric acid, phosphoric acid, or BHT Effluent in the SACS wash make up tank(s) or BHT. The equipment and lines that are part of Upstream Operations or are identified as Mixed-Use, Grandfathered, or BHT Recovery Units may be washed with SACS either from the BHT or the SACS wash make up tank and the solutions may be returned to the BHT.

In addition, the BHT will enable Mosaic to recover the value of wastes generated from the use of SACS, PACS, Non-Hazardous Aqueous Cleaning Solution, Process Wastewater, Phosphogypsum

Stack System Wastewater, BHT Effluent from pipes, tanks, process equipment, or other storage or transport units that: (i) are part of Upstream Operations or AFIP, (ii) serve to manage, store, or transport Bevill-Exempt Wastes; or (iii) are identified as Mixed-Use, Grandfathered Units, or BHT Recovery Units in this Facility Report. In accordance with the BMP, the BHT will also enable Mosaic to recover spills and leaks in Containable Impervious Areas described in Section VII of this Report. The BHT may also receive transfers from the GHT in accordance with Section VI. Compliance Projects, B.2. Project Operations.

The BHT shall in turn return the recoverable streams into Upstream Operations where their values are recovered or managed through the following (Diagram 1: BHT Inputs and Effluents):

a. as an intermediate wash on the filter, prior to the final cake wash, to inhibit scale formation. This wash ultimately circulates back to the reactor (attack tank); and/or

b. as direct make up to the Phosphoric acid reactors; and/or

c. added to the rock grinding circuit where it will be pH adjusted using limestone slurry; this mixture ultimately ends up in the slurry fed into the phosphoric acid reactors; and/or

d. discharged to the Phosphogypsum Stack System, if in compliance with the LDR standards set forth in 40 C.F.R. Part 268, Subpart D; and/or

e. If the P₂O₅ content is at least 8%, the BHT Effluent may be placed in the evaporator feed tanks for P₂O₅ recovery.

B. GHT Related Projects

1. Project Descriptions

Project 4: Upgrade Granulation Plants’ Pads and Sumps (Upgraded Recovery System)

Mosaic will modify or install, as needed, containment pads and sumps in each granulation plant to improve the capture of spills, leaks and cleaning solutions so materials may be returned to the granulation process via the GHT. This will include the four (4) granulation plants at New Wales - #1 DAP/MAP, #3 GMAP, #2 DAP East and #2 DAP West, as identified in the New Wales Facility Report.

Project 5: Granulation Plant Re-slurry System (DAP2 East and West)⁸

Mosaic will install a product recovery tank, hopper, piping, steam feed, valves, agitator, and pumps to recover wet fertilizer product from the DAP 2 East & West plants. The resulting slurry will be fed to the acid scrubber system for consumption in the granulation process.

Project 6: Granular Holding Tank and Wash Solution System in the Granulation Plant

Mosaic will install two Granular Holding Tank (GHT)⁹ systems- one in DAP2 East & West and the other in #1 DAP/MAP and #3 GMAP (Figure 14). The GHT plus piping, pumps, and instrumentation (together the “GHT system”) will transport and recirculate wash solution between GHT Recovery Units and the GHT and consume the wash solution in the granulation plants (DAP2 East & West, #1 DAP/MAP and #3 GMAP) as specified in Section VI.B.2 below.

2. Project Operations

The GHT system will enable Mosaic to recover the value of wastes generated from the use of SACS, PACS, Non-Hazardous Aqueous Cleaning Solution, Process Wastewater, Phosphogypsum Stack System Wastewater, or GHT Effluent from pipes, tanks, process equipment, or other storage or transport units identified as GHT Recovery Units or manage those wastes as described in Section 3. Granulation Plants Cleaning Procedures of the BMP. In accordance with the BMP, the GHT will also enable Mosaic to recover spills and leaks in Containable Impervious Areas described in Section VII of this Report.

A. The GHT shall in turn reuse or recover the recoverable streams as follows:

a. consumed in the acid scrubber system for consumption in the granulation process; and/or

b. consumed directly into the granulation reactor; and/or

c. added to the re-slurry system; and/or

⁸ DAP1 and GMAP3 already have reslurry systems for each plant.

⁹ Although Mosaic plans to install more than one GHT, for simplicity this Report will use the singular “GHT” to describe any and all GHTs that will be installed at Mosaic’s New Wales facility.

27

Mosaic New Wales

Facility Report

d. recirculated to clean GHT Recovery Units; and/or

B. In GHT cleaning situations identified in Section 4, GHT Cleaning - GHT Recovery Units, of the BMP, Mosaic may transfer the contents of the GHT to the BHT if they are RCRA non-hazardous. If the contents of the GHT are hazardous only for the RCRA corrosivity characteristic (pH< 2), Mosaic may transfer the contents to the BHT no more than two times per calendar year. The GHT shall then be washed with a cleaning solution (SACS, PACS, Process Wastewater, Phosphogypsum Stack System Wastewater, or NHACS). If the wash solution is hazardous only for RCRA corrosivity (pH< 2), it may be transferred to the BHT not more than two times per calendar year. If the solution is non-hazardous, it can be transferred to the BHT or sent to the Phosphogypsum Stack System.

C. In addition to GHT cleaning situations in B, in non-routine situations (such as mechanical failure in the Granulation Plant, unexpected plant outages, electrical power failures, hurricanes or similar weather events or unexpected problems during startups) and if the GHT is (or imminently will be) at or above 90% (full), Mosaic may transfer GHT Effluent if non-hazardous or hazardous only for the RCRA corrosivity characteristic (pH< 2) to the BHT, in order to create additional capacity in the GHT, until the GHT’s capacity is at 50% provided that Mosaic:

i) Manages use of the GHT to BHT transfer line by locking the valve on the transfer line or a system interlock requiring a code to activate;

ii) Obtains approval from its area manager to make the transfer; and

iii) Includes information on each transfer in its reports to the EPA and FDEP as required in Paragraph 41 of the CD.

If Mosaic chooses not to reuse or recover the GHT Effluent as described above, the GHT Effluent must instead be managed in accordance with RCRA.

VII. Containment of Phosphoric Acid Product Spills and Leaks

Any impervious¹⁰ manufacturing or storage areas not identified in this section as Containable Impervious Areas are considered to be Non-Segregable Areas.

Non-Segregable Areas

Mosaic New Wales Phosphoric Acid Plant has approximately 80% impervious surfaces with about 50% of it being acid brick and vinyl ester resin lined. The concrete pad is sloped towards concrete-lined trenches that transport any leaks and spills to the Phosphogypsum Stack System (Figure 8). Process water flows through the trenches at a rate of approximately 86,000 GPM to the Phosphogypsum Stack system. Due to the engineered slope of the concrete pad in these areas and the configuration of the Phosphoric Acid Plant, small spills and leaks of phosphoric acid and sulfuric acid onto the concrete pad cannot be feasibly segregated (“non-segregable areas”) and are mixed in the trenches with the Process Wastewater flowing to the Phosphogypsum Stack system and managed pursuant to Appendix 5, BMP. Mosaic may manage small spills and leaks of acid within the concrete areas of the Phosphoric Acid plant (Figure 8) in accordance with the BMP.

Containable Impervious Areas

a. Phosphoric Acid Unloading (post BHT project) (Figure 9)

¹⁰ Note, the use of the term “impervious” in this section does not refer to a particular definition of impervious or a particular leakage rate, but instead is used to mean a surface barrier to penetration, such as concrete, liners, steel, epoxy, etc. The term impervious in this section does not include gravel or soil.

i. DAP2 West (Figure 8)

Spills and leaks of phosphoric acid, sulfuric acid, and cleaning solutions onto impervious areas designated by Figure 9 and Figure 10 (“containable impervious areas”) shall be separately contained and then recovered in accordance with the BMP. The foregoing shall not relieve Mosaic of its obligations under any applicable law.

Other Areas

Any leak or spill of a hazardous material, including phosphoric acid and sulfuric acid, that is not contained within the Containable Impervious Areas or Non-Segregable Areas of the plant shall be managed in accordance with the BMP. The foregoing shall not relieve Mosaic of its obligations under any applicable law.

VIII. Proposed Phosphoric Acid Production Operations

Mosaic has advised EPA and FDEP that it is considering one or more of the following projects at its New Wales facility, but planning has not evolved to where detailed information is available.

Figure 11 depicts Upstream, Mixed-Use, and BHT Recovery Units. In the event that Mosaic reconfigures its Facility in accordance with Figure 12 and Figure 13 or Diagrams 4-7, then Figure 12 and Figure 13 shall replace Figure 11 as identifying Upstream Operations, Grandfathered Units, BHT Recovery Units and Mixed-Use Units for the Phosphoric Acid plant.

However, the Consent Decree does not bind Mosaic to implement the proposed project(s) as depicted in Figure 12 and Figure 13 or Diagrams 4-7. If Mosaic chooses to implement any changes through a different process than any of those depicted in Figure 12 and Figure 13 or Diagrams 4-7 in this Facility Report, then it shall be modified prior to implementation pursuant to Section XVIII (Modification) of the Consent Decree and EPA and FDEP will determine whether the new process as designed involves Upstream Units, Mixed-Use Units, BHT Recovery Units or Downstream Units and amend the Facility report to memorialize those determinations consistent with the descriptions below. Such determination shall be conditioned upon the new process being built substantially as designed. If the new process deviates from that standard, EPA and FDEP will determine whether the new process as built involves Upstream Operations, Mixed-Use Units, Grandfathered Units, BHT Recovery Units or Downstream Operations and amend the Facility Report to memorialize those determinations consistent with the descriptions below.

II. Background⁴

Mosaic Riverview’s primary commercial products include solid ammoniated phosphate fertilizers: monoammonium phosphate (MAP) and diammonium phosphate (DAP), MicroEssentials^® (MES) as well as fluorosilicic acid (FSA). DAP is manufactured in two production trains designated as #5 DAP and #6 DAP/MAP. MAP is also produced in #5 DAP or # 6 DAP/MAP. Ammonia and phosphoric acid are the primary reactants for MAP, DAP and MicroEssentials^® and are consumed in the production of ammoniated fertilizers on-site.

Phosphoric acid is produced by the digestion of phosphate rock with sulfuric acid. Mosaic manufactures phosphoric acid in one production plant, with two distinct reactors on-site. The reaction yields phosphoric acid and phosphogypsum (gypsum). Gypsum is filtered from the phosphoric acid on rotating pan filters, slurried with Process Wastewater in Gypsum Slurry Tanks, and the resultant slurry is pumped to a lined Phosphogypsum Stack. Because the production of phosphoric acid is a water-intensive process and water is used throughout the process (e.g., as acid dilution, in the ball mills, evaporators, condensers, and as a pipe and tank cleaning agent), approximately 500 million to 1.5 billion gallons of Process Wastewater are constantly stored in and circulating throughout the facility’s Phosphogypsum Stack System.

Mosaic Riverview deposits slurried gypsum in a clay-lined Phosphogypsum Stack (gypstack). An expansion to the gypstack is complete and is lined with 60-mil high density polyethylene (HDPE). The gypstack and the expansion are located northeast of the facility, east of US Hwy 41. The

Facility Report

combined lined gypstack operates in conjunction with the 80-mil HDPE lined Phosphogypsum Stack system.

Mosaic’s Riverview Phosphogypsum Stack system is lined with 80-mil HDPE. The pond system consists of a transfer pond located directly east of the production complex, and the pond’s connecting ditches. Mosaic Riverview operates the Phosphogypsum Stack System under an Industrial Wastewater Facility Permit issued by the Florida Department of Environmental Protection (FDEP).

III. First Saleable Products at Mosaic

The line marking the division between Upstream and Downstream Operations lies at the point of generation of the First Saleable Product. Mosaic Riverview generates two phosphoric acid First Saleable Products used as direct feedstocks to MAP or DAP production:

● 30% phosphoric acid that is routed to MAP or DAP production rather than to further concentration steps;

● 54% clarified phosphoric acid (greater than 1% solids) that is also routed to either MAP or DAP production.

Riverview also produces fluorosilicic acid (FSA) as a First Saleable Product. Downstream operations at Mosaic Riverview are associated with the storage, transport or use of FSA and of the phosphoric acid First Salable Products in MAP, DAP, and MES operations.

IV. Phosphoric Acid and FSA Production - Phosphoric Acid Plant

Figure 13 identifies Upstream Operations, BHT Recovery Units, Mixed-Use Units, and Grandfathered Units within Mosaic Riverview’s Phosphoric Acid Plant.

Mosaic Riverview’s Phosphoric Acid Plant has approximately 90% impervious surfaces and approximately 50% of the Plant has 40-mil HDPE liner installed below the concrete acid pads within contained areas. Below-grade concrete or acid-brick lined trenches and underground polyethylene piping throughout the Plant convey Process Wastewater from the Plant to the Phosphogypsum Stack system at a flow rate of approximately 60,000 GPM. The main Process Wastewater return ditches within the plant are composed of high performance concrete. The entire phosphoric acid plant is encompassed by a bentonite slurry wall that vertically intersects the limestone/bedrock layer.

A. Standard Acid Flow Configuration

The Phosphoric Acid Plant produces three concentrations of phosphoric acid for use in fertilizer manufacturing: 30% P₂O₅⁵, 43% P₂O₅, and 54% P₂O₅⁶. The 30% acid that is not used directly as feedstock to fertilizer manufacturing is further processed to 54% P₂O₅ in Upstream Operations. The

⁵ All concentrations of P₂O₅ are approximate and fluctuate slightly.

⁶ Note that although the terms P₂O₅ and phosphoric acid (H₃PO₄) are used interchangeably, the concentrations are not interchangeable. Mosaic manufactures phosphoric acid, however, in this document we refer to the concentration of the acid in terms of P₂O₅ concentration, rather than phosphoric acid concentration. P₂O₅ concentration can be converted to an approximate concentration of phosphoric acid by multiplying by 1.3808. Phosphoric acid is converted to an approximate concentration of P₂O₅ by multiplying by 0.7242.

Facility Report

standard phosphoric acid manufacturing process described below is illustrated in process flow diagram (Figure 4). Deviations from the standard acid flow configuration are necessary on periodic short-term intervals.

Mosaic Riverview produces phosphoric acid in two reactors designated as the Phosphoric Acid Reactor and the Dorrco Phosphoric Acid Reactor. The acid from both reactors mixes at the 30% Clarifier Feed Tank (“30 CFT” - 55T001). Prior to mixing at the 30 CFT (55T001), the acid flow is as follows:

Phosphoric Acid Reactor:

Post-reactor, unclarified 30% acid is pumped through the # 3 Filter to the #3 Filter #1 Filtrate Tank (41T001) and/or through the #1 Filter #1 Filtrate Tank (212306) then to the 30 CFT (55T001).

Phosphoric Acid Dorrco Reactor:

Post-reactor, unclarified 30% acid is pumped to the Phosphoric Acid Dorrco Digester (“Digester”) for aging (additional gypsum crystallization/solids formation) and then through the #1 Filter to the #1 Filter #1 Filtrate Tank (212306) and/or through the #2 Filter to the # 2 Filter # 1 Filtrate tank (31T24) and then to the 30 CFT (55T001).

C. Phosphoric Acid Transfer to Downstream Operations

1) Acid Transfer between the Phosphoric Acid Plant and the Dock Tanks (BHT Recovery Units)

Mosaic Riverview has two primary transfer lines that serve to transport 54% phosphoric acid from the Phosphoric Acid Plant to the Dock Tanks. The East 54 Overs Line and the West 54 Overs transfer lines transfer 54% clarified phosphoric acid from 54% Clarifier to East Dock Tank (25T11) or West Dock Tank (25T10).

All transfer lines described above are cleaned with cleaning solution to remove precipitated solids and scale to maintain acceptable pressure levels and acid flow rates. The locations of the transfer lines are illustrated in Figure 7 and Figure 8. The estimated line lengths and cleaning frequencies are listed in Table 4.

2) Acid Transfer between the Phosphoric Acid Plant and the #6 DAP/MAP (BHT Recovery Units)

Mosaic Riverview has two primary transfer lines that serve to transport 30% phosphoric acid from the Phosphoric Acid Plant to #6 DAP/MAP. The “B-30” or the “C-30” transfer lines transport 30% acid from the 300K Tank (24T19) to the #6 DAP/MAP primary acid scrubbers.

Mosaic Riverview has three primary transfer lines that serve to transport 54% phosphoric acid between the Phosphoric Acid Plant and #6 DAP/MAP. The “A Unders” line transports unclarified 54% acid from the 54 Clarifier (55CL002) to the #6 DAP/MAP 54% Acid Tank (“60K” - 30T04). The “East Fill Line/East Transfer Line” and “West Fill Line/West Transfer Line” transport clarified 54% acid from the East and West Dock Tanks (25T11 and 25T10, respectively) to #6 DAP/MAP Day Tank.

All transfer lines described above are cleaned with cleaning solution to remove precipitated solids and scale to maintain acceptable pressure levels and acid flow rates. The locations of the transfer lines are illustrated in Figure 7. The estimated line lengths and cleaning frequencies are listed in Table 5.

3) Acid Transfer between the Phosphoric Acid Plant to #5 DAP (BHT Recovery Units)

Mosaic Riverview has two primary transfer lines that serve to transport 30% phosphoric acid between the Phosphoric Acid Plant and #5 DAP. The “A-30” and “B-30” transfer lines transport 30% acid from the 300K Tank (24T19) to the #5 DAP Acid Scrubber.

Mosaic Riverview has two primary transfer lines that serve to transport 54% phosphoric acid between the Phosphoric Acid Plant and #5 DAP. The “East Fill Line/East Transfer Line” and “West Fill Line/West Transfer Line” transport clarified 54% acid from the East and West Dock Tanks (25T11 and 25T10, respectively) to #5 DAP 54% Acid Tank (33T01).

All transfer lines described above are cleaned with cleaning solution to remove precipitated solids and scale to maintain acceptable pressure levels and acid flow rates.

4) Acid Transfer between the Phosphoric Acid Plant and Truck Loading (BHT Recovery Units)

Riverview has one transfer line, the East 54 Clarifier feed, which serves to transport unclarified 54% phosphoric acid from the Phosphoric Acid Plant to Truck Loading. The line is cleaned with cleaning solution to remove precipitated solids and scale to maintain acceptable pressure levels and acid flow rates. The location of the transfer line is illustrated in Figure 5. The estimated line lengths and cleaning frequencies are listed in Table 2.

D. Fluorosilicic Acid (FSA) Standard Process Configuration

Mosaic Riverview recovers fluoride vapors from several evaporators. The recovery of fluoride vapors produces FSA. A generic depiction of the FSA production process is illustrated in Diagram 1.

FSA is produced as part of the first and second stage evaporation of phosphoric acid. Evaporators #1, 2, 3, 4, 5, 6, 7, 8, 9, and 10 each have a FSA recovery unit, also called a “Swift Tower,” integrated with a barometric condenser. The Swift Tower receives gas emitted from the concentration of 28% P₂O₅ to 43% P₂O₅ (for first stage evaporators – #1, 2, 3, 4, 9 and 10) and 43% P₂O₅ to 54% P₂O₅ (for second stage evaporators - #4, 5, 6, 7, 8) through evaporation. The gas is condensed in the Swift Tower and the liquid is continuously recirculated through a seal tank and back through the Swift Tower to maintain the seal and operation of the FSA Swift Tower.

FSA is not always produced. When FSA is not being produced for sale or use as a cleaning solution, the gases pass through the Swift Tower to the barometric condenser, there is no recirculation of FSA through the Swift Tower, and therefore FSA is not produced. Even when FSA is not being produced, the FSA Seal Tank remains an essential part of the Phosphoric Acid Evaporator by sealing the Swift Tower downleg.

When FSA is being produced for sale, recirculated liquid will continue to absorb fluoride vapors until the desired strength of FSA is obtained. FSA for sale is a solution of approximately 23-26% strength and specific gravity of 1.20-1.23.

Once the FSA reaches the desired strength for sale, a slip stream from the recirculation line between the FSA Seal Tank and FSA Swift Tower is sent to the FSA Scrubber Liquor Tank (25T12). In the FSA Scrubber Liquor Tank (25T12) the solution is isolated and tested for meeting customer specifications. Solutions meeting customer specifications in the Scrubber Liquor tank are transferred to the FSA Storage Tanks: FSA “A” Tank (25T07), FSA “B” Tank (25T08), and FSA “C” Tank (25T09) and sold to customers off-site.

Prior to commencement of operations of the BHT, if the solution does not meet the minimum customer specifications, within 90 days of that determination, the contents from the FSA Scrubber Liquor Tank (25T12) must be:

1. Returned to the #1 Evaporator Feed Tank (26T01), #3 Evaporator Feed Tank (26T03) or #4 Evaporator Feed Tank (26T04) for reprocessing and recovery of acid value when FSA is being recovered for sale; or

2. Sent to the Phosphoric Acid Reactors for reprocessing and recovery; or

15

Mosaic Riverview

Facility Report

3. Sent to the 43 CFT (26T02) for reprocessing and recovery of acid values when FSA is being recovered for sale and/or internal consumption; or

4. Discharged to the Phosphogypsum Stack System.

Following commencement of operations of the BHT, if the solution does not meet the minimum customer specifications, within 90 days of that determination, the contents from the FSA Scrubber Liquor Tank must be:

1. Returned to the #1 Evaporator Feed Tank (26T01), #3 Evaporator Feed Tank (26T03) or #4 Evaporator Feed Tank (26T04) for reprocessing and recovery of acid value when FSA is being recovered for sale; or

2. Sent to the Phosphoric Acid Reactors for reprocessing and recovery; or

3. Sent to the 43 CFT (26T02) for reprocessing and recovery of acid values when FSA is being recovered for sale and/or internal consumption; or

5. Used as FSA Cleaning Solution (FSACS) and then sent to the Big Holding Tank, as described in Section VI. Compliance Projects of this Report for reprocessing and recovery of acid values; or

6. Discharged to the Phosphogypsum Stack System, if in compliance with the land disposal restriction (LDR) standards set forth in 40 C.F.R. Part 268, Subpart D.

Because the sampling cannot take place instantaneously, it may be also necessary at times to transfer FSA from the FSA Scrubber Liquor Tank to the FSA “A” Tank (25T07), FSA “B” Tank (25T08), or FSA “C” Tank (25T09) before sampling results are obtained or a customer for this FSA is found.

Prior to commencement of operations of the BHT, if the solution does not meet the minimum customer specifications, within 90 days of that determination, the contents from the FSA “A” Tank (25T07), FSA “B” Tank (25T08), or FSA “C” Tank (25T09) must be:

1. Returned to the #1 Evaporator Feed Tank (26T01), #3 Evaporator Feed Tank (26T03) or #4 Evaporator Feed Tank (26T04) for reprocessing and recovery of acid value when FSA is being recovered for sale and/or internal consumption; or

2. Sent to the Phosphoric Acid Reactors for reprocessing and recovery; or

3. Sent to the 43 CFT (26T02) for reprocessing and recovery of acid values when FSA is being recovered for sale or internal consumption; or

4. Discharged to the Phosphogypsum Stack System.

Following commencement of operations of the BHT, if the solution does not meet the minimum customer specifications, within 90 days of that determination, the contents from the FSA “A” Tank (25T07), FSA “B” Tank (25T08), or FSA “C” Storage Tanks must be:

1. Returned to the #1 Evaporator Feed Tank (26T01), #3 Evaporator Feed Tank (26T03) or #4 Evaporator Feed Tank (26T04) for reprocessing and recovery of acid value when FSA is being recovered for sale or internal consumption; or

6. Discharged to the Phosphogypsum Stack System, if in compliance with the land disposal restriction (LDR) standards set forth in 40 C.F.R. Part 268, Subpart D.

Prior to commencement of operations of the BHT, FSA meeting customer specifications in the FSA Storage Tanks: FSA “A” Tank (25T07), FSA “B” Tank (25T08), and FSA “C” Tank (25T09), will not be mixed with FSA that has not yet been tested to determine if it meets customer specifications.

Prior to commencement of operations of the BHT, FSA produced for use as a cleaning solution may continue to be managed consistent with Mosaic’s consolidated waste management practices submittal dated September 8, 2015. Following commencement of operations of the BHT, FSA produced for use as a cleaning solution may be used and then must be sent to the Big Holding Tank, as described in Section VI Compliance Projects of this Report, for reprocessing and recovery of acid values.

Mosaic Riverview has one primary transfer line, FSA Shipping Line that serves to transport FSA between the FSA Storage Tanks and the Rail and Truck Loadout Area. The location of the transfer line is illustrated in Figure 6. The line designation and cleaning frequency is listed in Table 3.

B. Granulation Plants

Mosaic Riverview’s granulation process consists of two basic parts: (1) the wet (e.g., reactor, acid scrubber system); and (2) the dry side (e.g., granulator, dryer).

In addition, Mosaic Riverview will install a re-slurry system that recovers product that becomes wet and cannot be recovered through the dry side’s reclaim system. Mosaic will mix the product in a re-slurry tank with 30% acid, fresh water and/or GHT effluent as a batch process. This slurry will then be fed back into the acid scrubber system for recovery.

MAP, DAP and MES manufacturing operations are Downstream Operations; however, the units listed below are Recovery Units and are identified within the perimeters shown in Figure 12.

The following equipment in the Granulation Plant are BHT Recovery Units. Wastes from BHT Recovery Units are recovered into Upstream Operations as designated in this Report or to the BHT itself as described in Section VI. Compliance Projects (Projects 1 and 2) of this Report and Sections 3 and 6 of the BMP:

● #5 DAP 54% Acid Tank (33T01);

● #6 DAP 54% Acid Tank (“60K”- 30T04);

● East Dock Tank (25T11); and

22

Mosaic Riverview

Facility Report

The projects described below are not all the projects in Appendix 6 (Compliance Schedule) to the Consent Decree but are the projects that are recovery related – the BHT, GHT and reslurry systems. Timeframes for completion of the projects are found in Appendix 6 (Compliance Schedule) to the Consent Decree.

Projects 1 and 2 comprise a plan that will enable Mosaic Riverview to clean Upstream, Mixed-Use, Grandfathered, and BHT Recovery Units and recover value from the wastes as described below.

Projects 3, 4, and 5 are projects related to the Downstream Operations in Granulation and recovery of material in the granulation process.

A. BHT and Cleaning Solution Return Piping Projects

1. Project Descriptions

Project 1: Big Holding Tank and Wash Solution System in the Phosphoric Acid Plant

The Big Holding Tank and wash solution system (together designated the “BHT system”) project in the Phosphoric Acid Plant shall install new tank(s) piping, and controls to enable Mosaic to recover the value of wastes, as specified in Section VI.A.2 Project Operations below.

Mosaic will install two new BHTs for the BHT system. One of the tanks may be used in services other than BHT when not operating as a BHT (which other use shall not alter or nullify the status of the backup tank as a BHT Recovery Unit or preclude its use as a part of Upstream Operations, if appropriate). The BHT backup tank(s) will be used during cleaning and/or maintenance of the BHT tank. Cleaning waste from the BHT backup tank will be handled in the same way as the cleaning waste from the BHT itself as described in Section 2. Phosphoric Acid Plant Cleaning Procedures of the BMP.

In addition, new or upgraded pumps, motors, small pump tanks, and instrumentation may be needed to ensure the return to the BHT cleaning wastes and spills and leaks of: (1) phosphoric acid, sulfuric acid, FSA, SACS, PACS, FSACS, or BHT Effluent; or (2) NHACS, Process Wastewater, or Phosphogypsum Stack System Wastewater when mixed with any of the preceding solutions due to spills, leaks, or cleaning of leaks and spills to the BHT. Project 1 necessarily coincides with Project 2 below.

Project 2: Cleaning Solution Return Piping

Mosaic will install new piping to enable Mosaic to: (1) clean phosphoric acid transfer lines from the Phosphoric Acid Plant to the #6 DAP/MAP and #5 DAP Granulation Plants and the Dock Tanks and return those cleaning wastes to the BHT; (2) clean BHT Recovery Units located in the Granulation Plants and return those wastes to the BHT; and (3) clean FSA system and return those wastes to the BHT.

2. Project Operations

23

Mosaic Riverview

Facility Report

The wash solution system will be comprised of the BHT and the SACS make up tank(s), along with pumps and piping to supply cleaning solution to units that are part of Upstream Operations, or are identified as Mixed-Use, Grandfathered, or BHT Recovery Units.

Phosphogypsum Stack System Wastewater, Process Wastewater, fresh water, condensate or other water sources will be mixed with sulfuric acid, FSA, phosphoric acid or BHT Effluent in the SACS wash make up tank(s) or BHT. The equipment and lines that are part of Upstream Operations or are identified as Mixed-Use, Grandfathered, or BHT Recovery Units may be washed with SACS either from the BHT or the SACS wash make up tank and the solutions may be returned to the BHT.

In addition, the BHT will enable Mosaic to recover the value of wastes generated from the use of SACS, FSA, FSACS, PACS, Non-Hazardous Aqueous Cleaning Solution, Process Wastewater, Phosphogypsum Stack System Wastewater, BHT Effluent from pipes, tanks, process equipment, or other storage or transport units that: (i) are part of Upstream Operations, (ii) serve to manage, store, or transport Bevill-Exempt Wastes; or (iii) are identified as Mixed-Use, Grandfathered Units, or BHT Recovery Units in this Report. In accordance with the BMP, the BHT will also enable Mosaic to recover spills and leaks in Containable Impervious Areas described in Section VII of this report. The BHT may also receive transfers from the GHT in accordance with Section VI. Compliance Projects, B.2. Project Operations of this Report.

The BHT shall in turn return the recoverable streams into Upstream Operations where their values are recovered or managed through the following (Figure 1):

a. as an intermediate wash on the filter, prior to the final cake wash, to inhibit scale formation. This wash ultimately circulates back to the reactor (attack tank); and/or

b. as direct make up to the phosphoric acid reactors; and/or

c. neutralized in the Pond Water Neutralization System and then added to the rock grinding circuit where it will ultimately end up in the slurry fed into the phosphoric acid reactors; and/or

d. discharged to the Phosphogypsum Stack System, if in compliance with the LDR standards set forth in 40 C.F.R. Part 268, Subpart D; and/or

e. if the P₂O₅ content is at least 8% the BHT Effluent may be placed in the evaporator feed tanks for P₂O₅ recovery.

B. GHT Related Projects

1. Project Descriptions

Project 3: Granulation Plant Re-slurry System

Mosaic will install product recovery tank, hopper, piping, steam feed, valves, agitator, and pumps to recover wet fertilizer product. The resulting slurry will be fed to the acid scrubber system for consumption in the granulation process. This may be one system for both granulation plants, or it may be two systems, one for each granulation plant.

Project 4: Granular Holding Tank and Wash Solution System in the Granulation Plant

Mosaic will install either one common or two Granular Holding Tank (GHT) systems for the #5 DAP and #6 DAP/MAP granulation plants (Figure 16). The GHT plus intermediate holding tanks, piping, pumps, and instrumentation (together the “GHT system”) will transport and recirculate wash solution between GHT Recovery Units and the GHT and consume the wash solution in the granulation plants (#5 DAP and #6 DAP/MAP) as specified in Section VI.B.2 Project Operations below.

Project 5: Upgrade Granulation Plants’ Pads and Sumps As Needed

Mosaic will modify or install, as needed, containment pads and sumps in each granulation plant to improve the capture of spills, leaks, and cleaning solution so materials may be returned to the granulation process via the GHT, as identified in the Riverview Facility Report.

2. Project Operations

The GHT system will enable Mosaic to recover the value of wastes generated from the use of SACS, PACS, Non-Hazardous Aqueous Cleaning Solution, Process Wastewater, Phosphogypsum Stack System Wastewater, or GHT Effluent from pipes, tanks, process equipment, or other storage or transport units identified as GHT Recovery Units or manage those wastes as described in Section 3. Granulation Plants Cleaning Procedures of the BMP. In accordance with the BMP, the GHT will also enable Mosaic to recover spills and leaks in Containable Impervious Areas described in Section VII of this report.

26

Mosaic Riverview

Facility Report

A. The GHT shall in turn reuse or recover the recoverable streams as follows:

a. consumed in the acid scrubber system for consumption in the granulation process; and/or

b. consumed directly into the granulation reactor; and/or

c. added to the re-slurry system; and/or

d. recirculated to clean GHT Recovery Units.

B. In GHT cleaning situations identified in Section 3: GHT Cleaning and Non-Routine Transfer Situations of the BMP, Mosaic may transfer the contents of the GHT to the BHT if they are RCRA non-hazardous. If the contents of the GHT are hazardous only for the RCRA corrosivity characteristic (pH£ 2), Mosaic may transfer the contents to the BHT no more than two times per calendar year. The GHT shall then be washed with a cleaning solution (SACS, PACS, Process Wastewater, Phosphogypsum Stack System Wastewater, or NHACS). If the wash solution is hazardous only for RCRA corrosivity (pH£2), it may be transferred to the BHT not more than two times per calendar year. If the solution is non-hazardous, it can be transferred to the BHT or sent to the Phosphogypsum Stack System.

C. In addition to GHT cleaning situations in B, in non-routine situations (such as mechanical failure in the Granulation Plant, unexpected plant outages, electrical power failures, hurricanes or similar weather events or unexpected problems during startups) and if the GHT is (or imminently will be) at or above 90% (full), Mosaic may transfer GHT Effluent if non-hazardous or hazardous only for the RCRA corrosivity characteristic (pH£ 2) to the BHT, in order to create additional capacity in the GHT, until the GHT’s capacity is at 50% (full), provided that Mosaic:

i) Manages use of the GHT to BHT transfer line by locking the valve on the transfer line or a system interlock requiring a code to activate;

ii) Obtains approval from its area manager to make the transfer; and

iii) Includes information on each transfer in its reports to the EPA and FDEP as required in Paragraph 41 of the CD.

If Mosaic chooses not to reuse or recover the GHT Effluent as described above, the GHT Effluent must instead be managed in accordance with RCRA.

VII. Containment of Phosphoric Acid Product Spills and Leaks

Any impervious⁸ manufacturing or storage areas not identified in this section as Containable Impervious Areas are considered to be Non-Segregable Areas.

Non-Segregable Areas

Approximately 50% of Mosaic Riverview’s Phosphoric Acid Plant’s impervious areas have 40-mil HDPE liner installed beneath them. The concrete pad is sloped towards concrete-lined trenches (denoted by orange lines in Figure 10) that transport any leaks and spills to the Phosphogypsum Stack System. Process Wastewater flows through the trenches at a rate of approximately 60,000 GPM to the HDPE-lined Phosphogypsum Stack system. Due to the engineered slope of the concrete pad in these areas and the configuration of the Phosphoric Acid Plant, small spills and leaks of phosphoric acid, sulfuric acid, and FSA onto the concrete pad cannot be feasibly segregated (“non-segregable areas”) and are mixed in the trenches with the Process Wastewater flowing to the Phosphogypsum Stack system and managed pursuant to Appendix 5, BMP to the Consent Decree. Mosaic may manage small spills and leaks of phosphoric acid, sulfuric acid, and FSA within the concrete areas of the Phosphoric Acid plant) in accordance with the BMP. There are some areas in the Phosphoric acid area that are not concreted and they are shown with redlines in Figure 10.

⁸ Note, the use of the term “impervious” in this section does not refer to a particular definition of impervious or a particular leakage rate, but instead is used to mean a surface barrier to penetration, such as concrete, liners, steel, epoxy, etc. The term impervious in this section does not include gravel or soil.

(iii) Mosaic obtains and/or modifies any permit(s) required by local, state, or federal agencies; and

(iv) Mosaic submits to FDEP and EPA for approval a modified version of this Facility Report with the changes identified at least 60 Days in advance of the reconfiguration or installation of said project; and

(v) if applicable, Mosaic submits to FDEP and EPA for approval any modified section(s) of Appendix 5 (Best Management Practices Plan) at least 45 Days in advance of the reconfiguration or installation of said project.

B. Future Installations

1. Any existing tank within the battery limits of the Phosphoric Acid Plant (Figure 13) which may or may not be storing phosphoric acid, can be converted to phosphoric acid storage service up to, but excluding Merchant Grade Acid. Any tank placed into phosphoric acid storage service shall be structurally adequate and physically compatible with the contents of the tank.

2. Up to a total of two new phosphoric acid tanks storing First Saleable Product may be added within the battery limits of the Phosphoric Acid Plant (Figure 13), where the stored phosphoric acid product in the new tank(s) will be sent for use in Granulation so long as the new unit performs the same function as the existing Grandfathered or BHT Recovery Unit tanks identified in this Facility Report. The installation of more than two such tanks shall require advance approval by EPA and FDEP in order to be considered a BHT Recovery Unit or a Grandfathered Unit.

3. APCDs (scrubbers) may be newly installed, replaced, or modified if they are servicing Upstream Units or Mixed-Use Units identified in this Facility Report. APCDs may not be reconfigured to service any Downstream processes or any chemical processes which they are not serving as identified in this Facility Report.

4. Phosphoric acid piping systems and underflow piping systems associated with Upstream Units, Mixed-Use Units, BHT Recovery Units, or Grandfathered Units identified in this Facility Report may be installed, replaced, or modified provided that the replacement or modified systems are located within the battery limits of the Phosphoric Acid Plant (Figure 13) or the Tank Farms, excluding DAP, and serve only the phosphoric acid production operations identified in this Facility Report for those Upstream Units, Mixed-Use Units, BHT Recovery Units, or Grandfathered Units.

INTRODUCTION

Mosaic has developed Appendix 5: Best Management Practices Plan (hereinafter either “BMP” or “Plan”) to reduce unintended (and seek to eliminate unauthorized) inputs of phosphoric acid, sulfuric acid, fluorosilicic acid (FSA), SACS, PACS, and FSACS to Process Wastewater entering the Phosphogypsum Stack System. Where possible, Mosaic will capture and reuse these acid loses.

Through the BMP, Mosaic has established procedures to address the management, tracking, and reporting of phosphoric acid, sulfuric acid, and FSA leaks and spills for four of its fertilizer production facilities—Bartow, New Wales, Riverview, and Uncle Sam¹—in areas of the phosphoric acid plants (post first-stage filtration, e.g. bird or belt filters), including acid clarification and evaporation, and in the granulation plants. The specific details of the BMP for the phosphoric acid and granulation plants are discussed in the Sections that follow and the referenced Attachments. Where noted, certain BMP procedures are dependent upon the commencement of operation of the compliance projects set forth in Appendix 6 (Project Narrative & Compliance Schedules), to the Consent Decree.

SECTION 1: PHOSPHORIC ACID PLANTS LEAK/SPILL DETECTION

SYSTEMS AND RESPONSE PROCEDURES

1.1        General

Mosaic will implement two approaches to increase the likelihood of detecting non-segregable acid leaks, spills and process upsets: operator inspections and process stream conductivity monitoring, which are discussed in greater detail below. While conductivity monitoring is exclusive to the Process Wastewater system (non-segregable areas), operator inspections also serve to identify observable leaks and spills of acids regardless of the area of the plant where they occur – non-segregable, contained impervious, or outside contained impervious area.

1.2        Release Reporting

Mosaic personnel are responsible for notifying the appropriate personnel immediately upon the identification of a leak or spill of any hazardous material listed in Attachment A, Table 1 BMP Actionable Volumes (hereinafter, “Table 1 Materials”) pursuant to this BMP. This BMP does not

¹ Mosaic’s Faustina facility is not covered under this Appendix and Mosaic’s Plant City facility is the subject of a separate BMP Plan developed under a separate consent decree.

5

relieve Mosaic of its obligation to provide any such notifications under applicable federal, state, or local laws.

1.3        Inspections

Operators shall visually inspect the plant for leaks and/or spills of phosphoric acid, sulfuric acid, and FSA during their normal rounds a minimum of twice per shift and document the inspections. The operator shall correct any leaks from valves, flanges, pumps, or any other equipment that can be readily and safely corrected at the time of discovery. The incident shall be recorded in the tracking database known as AON Risk Management software or any other future data collection system which replaces or supplements AON Risk Management software (hereinafter, collectively referred to as “AON”). Any leaks or spills in excess of the applicable volume listed in Attachment A, Table 1 BMP Actionable Volumes (hereinafter “BMP Actionable Volume (Table 1)”) shall be reported to management for further action and recorded in AON. Reporting responsibilities are outlined in Mosaic’s Spill Reporting Policy and Procedure.

1.4        Conductivity System Description: Non-Segregable Spills/Leaks²

New Wales, Bartow, Riverview, and Uncle Sam shall monitor key outgoing streams (see Attachment B) with a conductivity system to enable the continuous detection of changes in conductivity that indicate occurrence of detectable acid leaks and spills. Each key outgoing stream shall have a conductivity probe to continuously measure the conductivity of the Process Wastewater as shown in Attachment B of this Plan. The conductivity of the return Process Wastewater stream shall be displayed on the operators’ distributive control system, see Attachment B of this Plan.

If acid leaks or spills into an outgoing water or Process Wastewater stream, the conductivity of the water or Process Wastewater increases because the acid has a higher conductivity than the water. Visual alarms (see example in Attachment B of this Plan) shall be triggered if the conductivity increases beyond the set alarm limits for a 5-minute interval. Upon triggering of such an alarm, the area around the probe will be investigated. Individual conductivity probe locations are found in Attachment B of this Plan.

Individual conductivity probes will alarm based on the preliminary trigger values set for each probe found in Attachment B of this Plan. The targets shown in Attachment B of this Plan are the initial temperature compensated conductivity targets for Bartow, New Wales, Riverview and Uncle Sam, respectively. Pursuant to Section 9: BMP Performance Standards, of this BMP, Mosaic will monitor the conductivity probes at Bartow, New Wales, and Riverview for a year after June 30, 2015 and will monitor the conductivity probes at Uncle Sam for a year after January 31, 2016 to ensure settings are correct for alerting operations to leaks and spills within the limits of the probes when properly operated and calibrated.

When a visual alarm triggers, the operator shall inspect that piece of equipment or area of the plant for any problems and take appropriate measures to stop or minimize the release and minimize further impacts (see Attachment B of this Plan).

² Non-Segregable Areas are described in Facility Reports “Containment of Phosphoric Acid Product Spills and Leaks.”

6

The conductivity system shall be maintained in accordance with specific manufacturer recommendations or acceptable industrial practices and updated as needed. Conductivity meters will be checked monthly and the instruments calibrated if necessary. The calibration dates and probe alarm limits shall be documented in the maintenance management system that is in place at the time. Maintenance and calibration procedures are found in Attachment B of this Plan.

1.5        Tracking/Recording

AON shall be used to track leaks and spills and the remedial measures taken to address a leak or spill. The area management, engineering, and environmental departments shall use AON to ensure the prompt and proper execution of remedial measures. When plant personnel identify a leak, spill or process upset (e.g. filtrate tank overflow), resulting in a release, appropriate remedial measures shall be taken as outlined below. A record of the incident shall be entered within 24 hours of the incident into AON to log and track releases of Table 1 Materials. Supervisors shall be trained to enter incidents into AON. AON tracks specific information including date and time of release, date and time of report, a description of the incident, volume of the material, type of material, and additional supporting information. AON generates emails to specific personnel that identify the severity and location of the incident. Mosaic personnel are responsible for notifying the appropriate personnel immediately upon the identification of a leak or spill, except for minor leaks or spills that already have been remedied.

1.6        Reporting, Recovery, and Remedial Measures

Management and environmental staff shall be notified of leaks or spills with a reasonable potential to reach or exceed the BMP Actionable Volume (Table 1) as quickly as possible in order to verify the volume of the leak or spill and ensure that it is properly reported, documented, and corrected pursuant to this BMP.

Mosaic personnel are responsible for notifying the appropriate personnel immediately upon the identification of a leak or spill, except for minor leaks or spills that already have been remedied. AON shall be used to track leaks and spills and the immediate actions taken to address a leak or spill. The area management, engineering, and environmental departments shall use AON to ensure the prompt and proper execution of remedial measures.

1.6.1            Non-Segregable Areas of the Phosphoric Acid Plants:

1.6.1.1 Reporting

Any leak or spill of FSA, sulfuric acid, SACS, PACS, FSACS or phosphoric acid into a non-segregable area, as described in each Facility’s Facility Report, which is detected as a result of visual inspections, audible alarms, conductivity monitoring, or operational detections (e.g. pressure losses) must be logged into AON. See Section 1.6.1.2: Remedial Measures, of this BMP.

If the leak or spill has the potential to exceed the BMP Actionable Volume (Table 1) in a rolling 24-hour period, appropriate management and environmental staff shall be notified and the leak or spill shall be properly reported, documented, and corrected pursuant to this BMP.

7

1.6.1.2 Remedial Measures

If any leak or spill of a Table 1 Material into a non-segregable area, as described in each Facility’s Facility Report, with a reasonable potential to approach a BMP Actionable Volume (Table 1) within any rolling 24-hour period is discovered, Mosaic will take the following measures:

1) Investigate potential release sources.

2) Address any issues found.

a. Stop the release if possible, such as by flow diversion or by closing the release gate.

b. Generate a work order if needed to correct the issue.

3) Document the release in AON.

4) Report the release to EPA, FDEP, or LDEQ pursuant with the Consent Decree.

This BMP does not relieve Mosaic of its obligation to comply with any federal, state, or local laws applicable to such a leak or spill.

SECTION 2:  PHOSPHORIC ACID PLANT CLEANING PROCEDURES

2.1        General

SACS, FSA, PACS, or FSACS are periodically used to wash lines, filters, or other equipment within the phosphoric acid plant, including evaporation and clarification. The primary purpose for continuing to use SACS is to recover sulfate value and offset the amount of virgin sulfuric acid used. The primary purpose for continuing to use FSA and FSACS is to recover FSA value. The primary purpose for using PACS is to recover P₂O₅ value. The recovery of these solutions will contribute to decreasing the total dissolved solids in the Process Wastewater ponds.

SACS, FSA, FSACS and PACS shall be managed as shown in Diagram 1: Big Holding Tank Cleaning Solution and Solids Management Plan. Following commencement of operations of the Big Holding Tank (BHT), no SACS or PACS shall be placed into the Phosphogypsum Stack System, other than indirectly via the approved uses below. SACS PACS, FSA and FSACS shall be routed to the BHT (described in Section 7: Minimization of Operational Phosphoric Acid Inputs, of this Appendix) for consumption in the phosphoric acid plant so the BHT Effluent’s value can be realized through the following uses described in each Facility’s Facility Report:

1. Added to the filter prior to the final cake wash to inhibit scale formation. The filtrate from this wash is sent as recycle acid to the reactor (attack tank); or

2. Used as direct make up to the reactor attack tank; or

3. Added to the rock grinding circuit where it will ultimately end up in the slurry fed into the phosphoric acid reactor(s); or

4. If the P₂O₅ content is at least 8%, placed in the evaporator feed tank(s) for P₂O₅ recovery.

If for any reason the BHT Effluent is not recovered as outlined above, it must satisfy the RCRA land disposal restriction (LDR) standards prior to discharge to the Phosphogypsum Stack System (see Diagram 1).

Following commencement of operations of the BHT, if FSA has been transferred to BHT Recovery Units for sale or cleaning,³ no FSA or FSACS shall be placed into the Phosphogypsum Stack System from BHT Recovery Units, other than indirectly via the following:

1. Returned to the evaporator feed tank(s) that directly feed FSA-producing evaporators when FSA is being recovered for sale and/or internal consumption; or

2. Sent to phosphoric acid reactors for reprocessing and recovery of FSA values; or

3. Sent to the BHT as described in Section VI (Compliance Projects) of the respective Facility’s Facility Report for recovery of FSA values; or

4. Used as FSACS and then sent to the BHT for reprocessing and recovery of acid values.

If for any reason FSA or FSACS from BHT Recovery Units is not recovered as outlined above, it must

³FSA is not always recovered. When FSA is not being recovered for sale or cleaning, the gases pass through the Swift Tower to the barometric condenser, there is no recirculation of FSA through the Swift Tower, and therefore FSA is not produced. Even when FSA is not being recovered, the FSA Seal Tank remains an essential part of the Phosphoric Acid Evaporator by sealing the Swift Tower downleg.

SECTION 3:  GRANULATION PLANTS CLEANING PROCEDURES⁵

3.1        General

Mosaic’s intent is to minimize losses and to conserve and recover resources whenever feasible. Solutions and solids generated from cleaning granulation equipment other than BHT Recovery Units as described in the Facility’s Facility Report shall either be recovered in the granulation process or characterized to determine if they are hazardous under the RCRA Requirements for corrosivity (pH£ 2 or pH³ 12.5) and/or toxicity (Table 2). If the materials are not recovered to the granulation process and are hazardous, they shall be handled according to the RCRA Requirements. If these materials are not recovered to the granulation process and are non-hazardous, they can be discharged to the Phosphogypsum Stack System.

3.2        Line Cleaning

All lines within the granulation plant shall be washed with an aqueous cleaning solution (i.e., Process Wastewater, Phosphogypsum Stack Water, NHACS, SACS, PACS, FSACS, FSA or GHT Effluent). All cleaning solutions that enter the boundary of the granulation plant shall be handled according to Section 3.1: General, of this BMP.

3.3        Phosphoric Acid Tank Cleaning (BHT Recovery Units)

Following commencement of operations of the BHT, the following general steps shall be used in the cleaning of any phosphoric acid storage tank in the granulation plants (BHT Recovery Units). Empty the tank by feeding the remaining acid to the Granulation process or recovering phosphoric acid back to the phosphoric acid clarification process or another phosphoric acid tank within the Granulation area. Wash the tank with an aqueous cleaning solution (i.e., Process Wastewater, Phosphogypsum Stack Water, NHACS, SACS, PACS, FSACS, FSA or BHT Effluent) if needed. Fill the tank with cleaning solution and recirculate to facilitate cleaning for an appropriate period of time (typically 12-48 hours), until the scale is adequately removed. The wash may be repeated multiple times until adequately cleaned, and the wash solution (including entrained solids) sent to the BHT. Solids that are removed with high pressure cleaning with NHACS or by other mechanical means will be dewatered. The liquid portion of the dewatered solids will be recovered to the BHT. If the dewatered solids are non-hazardous, they will be transferred to the Phosphogypsum Stack System. If they are hazardous, they will be handled in compliance with the RCRA Requirements.

At Bartow, ammonia may be added as a scale softening agent to DAP Pond water, Phosphogypsum Stack System Wastewater, or Process Wastewater and the resulting cleaning solution is used to clean phosphoric acid storage tanks in the granulation plant. This non-hazardous spent wash solution shall only be recovered to the DAP process pond.

3.4        Acid Scrubber, Reactor and Tailgas Scrubber System Cleaning - GHT Recovery Units

Granulation plant scrubbers and reactors are cleaned with a cleaning solution based on the frequency of scale buildup.

The wash solution, such as Process Wastewater, DAP Pond water, Phosphogypsum Stack Wastewater, or NHACS is collected either in the Acid Scrubber or the Reactor and a continuous flow is sent to the Dry Side Equipment, such as the granulator, dryer, cooler, elevators, screens, milling equipment and the associated piping. The cooler may be washed as part of the Dry Side Equipment wash or separately. High pressure cleaning with NHACS or other mechanical means may be used to remove hard scale. Following commencement of operations of the GHT, liquids (including entrained solids) will be recovered to the GHT. Solids that are removed with high pressure cleaning or mechanical means will be dewatered, if needed. Following commencement of operations of the GHT, any liquid portion of these solids will be recovered to the GHT. The solids will be recovered back to the granulation process through either the dry reclaim system or the re-slurry system.

3.6        GHT Cleaning and Non-Routine Transfer Situations

3.6.1    GHT Cleaning

Following commencement of operations of the GHT, the following general steps shall be used in cleaning of the GHT(s) and the Riverview and New Wales GHT intermediate tanks. The tanks shall be emptied by recovering as much liquid (with entrained solids) as possible back into the granulation process and/or the BHT. Any residual volume that is hazardous only for RCRA corrosivity (pH£2) and cannot be recovered into the granulation process may be transferred to the BHT not more than two times per calendar year. The GHT shall then be washed with a cleaning solution (SACS, PACS, Process Wastewater, Phosphogypsum Stack System Wastewater, or NHACS). If the wash solution is hazardous only for RCRA corrosivity (pH£2), it may be transferred to the BHT; not more than two times per calendar year. If the solution is non-hazardous, it can be transferred to the BHT or sent to the Phosphogypsum Stack System.

3.6.2    Non-Routine Situations

In non-routine situations, such as mechanical failure in the Granulation Plant, unexpected plant outages, electrical power failures, hurricanes or similar weather events or unexpected problems during startups, Mosaic may transfer GHT Effluent that is hazardous only for RCRA corrosivity (pH£2) from the GHT to the BHT(s) as described in each Facility’s Facility Report.

3.7        Wash Down

NHACS (including fresh water or DAP Pond water) may be used for wash down of the floors, conveyor belts, and other equipment within the granulation plant. If non-hazardous, the resulting streams may be transferred to the Phosphogypsum Stack System or the DAP Pond. If the resulting streams are hazardous, they will be recovered to the GHT or characterized and handled in compliance with the RCRA Requirements.

The collection sumps for these containment pads shall pump to the granulation plant scrubbers, re-slurry tank, GHT or, if non-hazardous, may be discharged to a permitted National Pollutant Discharge Elimination System (NPDES) outfall. The sumps will be designed with pH probes that will allow storm water run-off during high rainfall to be diverted to the Phosphogypsum Stack System if pH > 2.0 or to a permitted NPDES outfall. This will eliminate excessive rain water getting into the GHT, diluting it and also leading to the tank level being high. The granulation plant acid scrubbers and re-slurry tank are designed to recover fertilizer materials, product and raw materials for consumption in the granulation process.

Cleaning solutions in the Granulation area (except for cleaning solutions from BHT Recovery Units) shall be managed as follows:

• If the resulting stream from the cleaning process is non-hazardous, the solution may be discharged directly to the Phosphogypsum Stack System or recovered in the granulation process via the GHT.

• If the resulting stream is hazardous, then the resulting solution shall be recovered in the granulation process via the GHT for recovery of product value.

Mosaic may transfer cleaning solution from GHT to BHT as specified in the Facilities’ Facility Reports.

9.2        Performance Criteria for Spill and Leak Detection

An initial data collection period of 12 months will be used to establish baseline performance criteria for spills, leaks, and other releases. Mosaic will monitor the conductivity probes at Bartow, New Wales, and Riverview for a year after June 30, 2015 and will monitor the conductivity probes at Uncle Sam for a year after January 31, 2016. Once BMP performance criteria and a baseline are established, Mosaic shall review the criteria quarterly. Based upon the reviews, BMPs will be updated as warranted to minimize leaks, spills, and other releases. Mosaic shall initiate additional review of the BMP Program under the following circumstances:

• At any time during a calendar quarter when two or more leak or spill events of phosphoric acid, sulfuric acid or FSA into “non-segregable areas” at the same facility have occurred that exceed the quantity shown in Table 1: BMP Actionable Volumes (Table 1) in a rolling 24-hour period.

• At any time during a calendar quarter when two or more leak or spill events of phosphoric acid, sulfuric acid or FSA inside a “containable impervious area” at the same facility have occurred that exceed the quantity shown in Table 1: BMP Actionable Volumes (Table 1) in a rolling 24-hour period.

• At any time during a calendar quarter when two or more leak or spill events of phosphoric acid, sulfuric acid or FSA have occurred outside of non-segregable or containable impervious areas at the same facility that exceed the Comprehensive Environmental Response, Compensation and Liability Act (CERCLA) Reportable Quantity.

³ Conductivity probes that are on units that use river water are measured in microSiemens. Ditch Conductivity 1 and Ditch Conductivity 2 probes will be on the Process Pond water, therefore milliSiemens are used.

⁴ Ditch conductivity probes 1 & 2 will be filled in after installation and generation of the baseline.

Maintenance

Each Mosaic concentrate plant uses manufacturer recommended calibration procedures specific to the type of probe. The four calibration methods that are being used are Bench Calibration using a User-Supplied Wire, Bench Calibration Using a Foxboro Calibration Plug and Solution Calibration and the Decade resistor box. Table 5 below shows methods that are being used at each of the sites. Probes are removed, cleaned and dried every time prior the calibration procedure is performed.

PHOSPHOGYPSUM STACK SYSTEM ALTERNATIVE

LINER REQUIREMENTS

    A.    MOSAIC BARTOW

Appendix 1 of this Consent Decree sets forth requirements for lining Phosphogypsum Stack Systems (“Stack Systems”) within five years of the Effective Date of this Consent Decree as a means of reducing or eliminating contamination migrating from such stacks. On January 10, 2011, Mosaic submitted a demonstration document titled “Overview of Seepage Control Features and Projected Groundwater Quality Impacts for Mosaic Fertilizer, LLC Bartow Phosphogypsum Stack System,” hereafter referred to as the “Bartow Demonstration,” proposing that alternate means of containment can meet the Environmental Protection Agency’s (EPA) and Florida Department of Environmental Protection’s (FDEP) environmental protection goals and obviate the requirement of Appendix 1, Attachment D, Section VII to, within five years of the Effective Date, line existing unlined Phosphogypsum Stack Systems in accordance with Appendix 1, Attachment C, Section VI, or within five years of the Effective Date, close existing unlined Phosphogypsum Stack Systems in accordance with Appendix 1, Attachment D. This Appendix identifies the specific Phosphogypsum Stack System components that, subject to the terms of the Consent Decree (including Paragraph 24(b) thereof), the EPA and FDEP have determined either meet the liner design standards of Appendix 1, Attachment C, Section VI, or are considered an acceptable alternative to those standards. The EPA and FDEP’s acceptance of the Bartow Demonstration for this purpose does not bind the EPA or the FDEP to the factual assertions and conclusions of the Bartow Demonstration. This Appendix also identifies the specific Phosphogypsum Stack System components that either meet the closure design standards of Appendix 1, Attachment D, or that are considered to be an acceptable alternative to the closure design standards of Appendix 1, Attachment D.

General Description

The Bartow Phosphogypsum Stack System consists of the Closed North Phosphogypsum Stack (North Stack) and its associated system components and the Lined South Phosphogypsum Stack Expansion (South Stack) and its associated system components (Figure 1). The following water bodies illustrated in Figure 1 are not part of the Phosphogypsum Stack System and as such are exempt from the liner requirements: Steel Lake, Lake Vondrasek, Bonny Lake, Terry Lagoon, Clear Water Pits, Lake Greener, Lake Law, Lake Donny and Brown Lake. In addition, Mosaic has identified other water bodies existing at Bartow that are not part of the Phosphogypsum Stack System.

The Lined DAP Pond is not associated with the North Stack System or South Stack System. It is associated with the production of monoammonium phosphate (MAP) and diammonium phosphate (DAP) fertilizers.

Florida Appendix 7

The North Stack-associated components include two lined auxiliary holding ponds on top of the North Stack (Lined North Pond and Lined South Pond), a Cooling Pond System, and Area 8E South (Emergency Diversion Impoundment). The Cooling Pond System includes the R1 and R2 Return Water Channels (“R1 Canal” and “R2 Canal”) on the west side of the North Stack, the closed Cooling Pond Area R-7 and the R-7 associated channel that runs along the north and east side of the North Stack, Area R3, Area R5, and Cooling Pond Area LR6 (Figure 2). The Cooling Pond System is used for process water management, as well as circulation and cooling of process water, and receives incidental discharges of gypsum slurry.

The South Stack-associated components include the South Stack Toe Ditches, Lined Surge Pond Area (“Area 2C”). Non-Process Wastewater ponds SR-South, SR-North and CJ-North are notable water features but they are not part of the Phosphogypsum Stack System.

The key components of Mosaic’s Demonstration rely mostly upon soil bentonite cut-off walls (“slurry walls”) installed as engineered seepage prevention features, and certain existing liners, as summarized below.

Soil Bentonite Cut-Off Walls

Closed North Stack

Currently the Closed North Stack and its Cooling Pond System have a 2 ¹⁄₂-foot thick slurry wall that extends 35 to 75-feet into the natural ground clay confining unit beneath the Stack System to mitigate lateral seepage from the North Stack System along the east and south walls. The slurry wall initiates at the northeast side of the North Stack and traverses the entire eastern side of the Cooling Pond System and southern end of the Cooling Pond System, and terminates at the southwest end of the North Stack at the R1 Return Water Channel. The location of the slurry wall is designated by the green line in Figure 2.

South Stack

Currently the South Stack and its associated Lined Surge Pond and South Stack Toe Ditches has a 2 ¹⁄₂-foot thick slurry wall that extends into the natural ground clay confining unit beneath the Stack System to mitigate lateral seepage from the South Stack System along the north, east and south walls. The slurry wall initiates at the northwest side of the South Stack and traverses the entire northern end, eastern side and southern end of the South Stack and terminates at the southwest end of the South Stack. The location of the slurry wall is designated by the green line in Figure 3.

Synthetic Liners

Closed North Stack

The Closed North Stack has an amended gypsum grassed cover over its side slopes and a grassed soil cover over the 40-mil HDPE liner installed within slope runoff ditches for closure. The only two areas not covered with a soil and grass top cover are the two 80-mil HDPE-lined auxiliary holding ponds situated atop the North Stack (Figure 2).

2

Florida Appendix 7

South Stack

The South Stack has 60-mil HDPE liners installed at an interim height within the stack. The liners cover the entire portion of the stack that receive phosphogypsum. The Lined Surge Pond at the western base of the South Stack is lined with a 80-mil HDPE liner that extends to the upstream slope of the perimeter earthen dike (Figure 3).

Liner Requirements for Specific Components of the Stack System and for Other Water Features

The following components or former components generally designated by red lines in Figure 4 of Mosaic Bartow’s North and South Stack Systems or adjacent water features listed above are not subject to the lining requirements of Appendix 1, Attachments C and D, as long as they do not hereafter receive Process Wastewater or Phosphogypsum (except in emergency situations as approved by the Florida Department of Environmental Protection).

1) Area 8E South (Emergency Diversion Impoundment)

2) Inactive North Stack (including the unlined portion underlying the RO Plant Area)

3) SR-South

4) SR-North

5) CJ-North

The following components of Mosaic Bartow’s North and South Stack Systems or process-water receiving ponds designated in purple in Figure 5 have existing engineered seepage control features that, as installed, either meet the liner design standards of Appendix 1, Attachment C, Section VI or are considered by EPA and FDEP to be environmentally protective and thus considered to be an acceptable alternative to the liner design standards of Appendix 1, Attachment C, Section VI (i.e. no additional equivalency determination necessary).

1) Lined North Pond (Inactive North Stack)

2) Lined South Pond (Inactive North Stack)

3) South Gypsum Stack Lined Vertical Expansion (Over Unlined Stack)

4) South Gypsum Stack Lined Surge Pond Area

5) Lined Cooling Pond Area LR6

6) Lined DAP Pond

7) Lined Ditch connecting R5 and LR6

8) Lined South Stack West Relief Ditch

9) Lined Booster Pump Spill Containment Area

The following components of Mosaic Bartow’s North Stack System designated by dark blue lines in Figure 6 deviate from the Government’s liner design standards of Appendix 1, Attachment C, Section VI but are determined to be environmentally protective and thus considered to be an acceptable alternative to the requirements of Appendix 1, Attachment C, Section VI (i.e. no additional equivalency determination necessary), subject to the Continued Monitoring Project below. All components in Mosaic Bartow’s South Stack System either do not deviate from the

3

Florida Appendix 7

Government’s liner design standards of Appendix 1, Attachment C, Section VI or have been previously approved by FDEP as equivalent to or an acceptable alternative to the lining requirements of Florida Administrative Code 62-673.400.

1) R1 and R2 Return Water Channels

2) Closed Cooling Pond Area R7

3) Area R7’s associated channel that runs along the north and east sides of the North Stack

4) Area R3

5) Area R5

The R-2 Canal Seepage Collection Area designated in Figure 2 does not fully conform to the liner design standards of Appendix 1, Attachment C, Section VI. EPA and FDEP anticipate that, once Mosaic implements the R-2 Canal Seepage Collection Area project set forth in Appendix 6 (RCRA Project Narrative & Compliance Schedule), it will be environmentally protective, and thus it is considered to be an acceptable alternative to the requirements of Appendix 1, Attachment C, Section VI (i.e. no additional equivalency determination necessary).

Continued Monitoring Project (In addition to the requirements of the FDEP NPDES permit)

1) Mosaic shall evaluate water level data collected from Piezometers located around the perimeter of the north stack slurry wall to monitor the performance of the slurry wall associated with the north stack (NPDES Permit # FL0267911), along with any monitoring well/piezometer data collected to monitor slurry wall performance associated with the south stack (NPDES Permit # FL0001589), to continue to confirm the slurry wall integrity.

Closed Components of Stack System

The following components of Mosaic Bartow’s Stack Systems have existing engineered closure covers that, as installed, either meet the closure design standards of Appendix 1, Attachment D, or are determined to be environmentally protective and thus are considered to be an acceptable alternative to the requirements of the closure design standards set forth in Appendix 1, Attachment D (i.e., no additional alternative determination necessary).

1) North Gypsum Stack Top Gradient (below lined AHPs)

2) North Gypsum Stack Side Slopes

3) South Gypsum Stack Top Gradient Below Vertical Expansion Liner

4) South Gypsum Stack Side Slopes (below vertical expansion)

5) Northern 45 acres of Cooling Pond Area R7

Florida Appendix 7

    B.    MOSAIC NEW WALES

Appendix 1 of this Consent Decree sets forth requirements for lining Phosphogypsum Stack Systems (“Stack Systems”) within five years of the Effective Date of this Consent Decree as a means of reducing or eliminating contamination migrating from such stacks. On August 16, 2010, May 27, 2011 and November 7, 2011, Mosaic submitted demonstration documents titled “Overview of Seepage Control Features and Projected Groundwater Quality Impacts for Mosaic Fertilizer, LLC New Wales Phosphogypsum Stack System,” hereafter referred to as the “New Wales Demonstration,” proposing that alternate means of containment can meet the EPA’s and FDEP’s environmental protection goals and obviate the requirement of Appendix 1, Attachment D, Section VII to, within five years of the Effective Date, line existing unlined Phosphogypsum Stack Systems in accordance with Appendix 1, Attachment C, Section VI or within five years of the Effective Date, close existing unlined Phosphogypsum Stack Systems in accordance with Appendix 1, Attachment D. This Appendix identifies the specific Phosphogypsum Stack System components that, subject to the terms of the Consent Decree (including Paragraph 24(b) thereof), the EPA and FDEP have determined either meet the liner design standards of Appendix 1, Attachment C, Section VI or are considered an acceptable alternative to those standards. The EPA and FDEP’s acceptance of the New Wales Demonstration for this purpose does not bind the EPA or the FDEP to the factual assertions and conclusions of the New Wales Demonstration. This Appendix also identifies the specific Phosphogypsum Stack System components that either meet the closure design standards of Appendix 1, Attachment D or that are considered to be an acceptable alternative to the closure design standards of Appendix 1, Attachment D.

General Description

The New Wales Phosphogypsum Stack System consists of the Closed North Phosphogypsum Stack (North Stack) and its associated system components and the Lined South Phosphogypsum Stack (South Stack) and its associated system components (Figure 1).

The North Stack-associated components include two lined auxiliary holding ponds on top of the North Stack (“Lined Surge Pond (LESP)-1 and LESP-2”), a below-grade auxiliary holding pond to the southwest of the North Stack and a Cooling Pond System. The Cooling Pond System is used for process water management, as well as circulation and cooling of Process Water, and receives incidental discharges of gypsum slurry. The Cooling Pond System consists of the main Cooling Pond, the North Channel, the East Channel, and the West Channel (Figure 2). Since closure of the North Stack, all these components (even those located on the North Stack) are now part of the operating South Stack System. Non-Process Wastewater Impoundment Area A-11 is a notable water feature used by the New Wales Facility but is not part of the Phosphogypsum Stack System. Mosaic has identified other water bodies existing at New Wales that are not part of the Phosphogypsum Stack System.

5

Florida Appendix 7

The South Stack-associated components include the Toe Ditches, comprised of the seepage collection ditch and the decant water/runoff collection ditch, circling the South Stack, and a lined auxiliary holding pond (LESP 3) on top of the South Stack (Figure 3).

The key components of the Demonstration rely mostly upon soil bentonite cut-off walls (“slurry walls”) installed as engineered seepage prevention features, and certain existing liners, as summarized below.

Soil Bentonite Cut-Off Walls

Currently the Closed North Stack and the surrounding Cooling Pond System have three 2 ¹⁄₂-foot thick slurry walls (two of which are interconnected) that extend 70 to 115-feet into the natural ground clay confining unit beneath the Stack System to mitigate lateral seepage from the North Stack and Cooling Pond System. The North Perimeter Dike and Plant slurry walls (which overlap and are interconnected) initiate at the northeast side of the North Perimeter Dike and traverse the entire northern alignment of the North Stack, encompass the Plant area, and terminate midway down the western side of the North Stack. The Phase I Expansion Area slurry wall (installed to hydraulically isolate the unlined cooling pond from the lined South Stack expansion area) initiates on the southwest end of the main Cooling Pond and West Channel and traverses the entire southern perimeter of the main Cooling Pond, and terminates at the southeast end of the main Cooling Pond. The location of the slurry walls are designated by the green line in Figure 1. Pursuant to Appendix 6 (RCRA Project Narrative & Compliance Schedule), Mosaic has completed a slurry wall extension project by overlapping the existing Expansion Area cut-off wall at the southwest corner of the Cooling Pond with a new slurry wall keyed 3 feet into bedclay that initiates about 900 feet east of the southeast corner of the Below Grade Unlined Auxiliary Holding Pond (AHP) and traverses the entire south and west perimeters of the AHP, terminating at a tie-in with the existing Plant slurry wall 400 feet north of the northwest corner of the AHP.

Synthetic Liners

Closed North Stack

The Closed North Stack has an amended gypsum grassed cover over its side slopes and a grassed soil cover over the 40-mil to 60-mil high density polyethylene (HDPE) liner installed atop the stack and mid-slope and toe drainage ditches, respectively, for closure. The only two areas not covered with a soil and grass top cover are the two 60-mil HDPE-lined auxiliary holding ponds situated atop the North Stack (Figure 2).

South Stack

The South Stack has 60-mil HDPE liners installed over the entire base of the stack including perimeter toe ditches and upstream slope of the perimeter earthen dike (Figure 3).

Florida Appendix 7

Liner Requirements for Specific Components of the Stack System and for Other Water Features

The following components or former components designated in red in Figure 1 of Mosaic New Wales’s Stack System or adjacent water features are not subject to the liner requirements of Appendix 1, Attachments C and D, as long as they do not hereafter receive Process Wastewater or Phosphogypsum.

1) Non-Process Water Impoundment Area A-11

2) Closed North Stack (except for LESP-1 and LESP-2)

3) Section 30 Freshwater Pond

4) SWRP-S plant non-process retention pond

5) SWRP-N plant non-process retention pond

The Northeast Sump that collects seepage from the North Toe Drain (see Figure 1) for pumping back into the process system does not fully conform to the liner design standards of Appendix 1, Attachment C, Section VI. EPA and FDEP anticipate that, once Mosaic implements the Northeast Sump project set forth in Appendix 6 (RCRA Project Narrative & Compliance Schedule), it will be environmentally protective, and thus it is considered to be an acceptable alternative to the requirements of Appendix 1, Attachment C, Section VI (i.e. no additional equivalency determination necessary).

The following components of Mosaic New Wales’s Stack System designated in purple in Figure 4 have existing engineered seepage control features that, as installed, either meet the liner design standards of Appendix 1, Attachment C, Section VI or are determined to be environmentally protective and thus are considered to be an acceptable alternative to the requirements of Appendix 1, Attachment C, Section VI (i.e. no additional alternative determination necessary).

1) South Gypsum Stack

2) South Gypsum Stack Toe Ditches

3) LESP-1

4) LESP-2

5) LESP-3 on South Stack

The following components of Mosaic’s Stack System designated in orange in Figure 5 deviate from the Government’s liner design standards of Appendix 1, Attachment C, Section VI, but are determined to be environmentally protective, and thus are considered to be an acceptable alternative to the requirements of Appendix 1, Attachment C, Section VI (i.e. no additional equivalency determination necessary).

1) Main Cooling Pond

2) East Channel

3) North Channel

4) West Channel

5) Below-Grade Unlined Auxiliary Holding Pond

Florida Appendix 7

Mosaic shall undertake the following additional project.

1) Mosaic shall investigate reasonable and practicable methods to reduce the volume of pond water within Mosaic’s main Cooling Pond that would be lost in the event of a sinkhole. Mosaic shall complete this review of potential methods within two years from the Effective Date of this Consent Decree and shall submit to EPA and FDEP its findings. The Parties: (1) will then confer to discuss the technical and economic viability of the findings; (2) if any technically and economically viable methods are identified and mutually agreed to as such, the parties shall discuss and agree upon the circumstances under which such methods will be implemented; and (3) agree that the foregoing obligations shall not be construed to require Mosaic to undertake, fund, or otherwise implement any methods evaluated under item 1 above unless agreement is reached between the parties, as noted in item 2 above.

Closed Components of the Phosphogypsum Stack System

The following components of Mosaic New Wales’s Stack System have existing engineered closure covers that, as installed, either meet the closure design standards of Appendix 1, Attachment D, or are determined to be environmentally protective and thus are considered to be an acceptable alternative to the requirements of the closure design standards set forth in Appendix 1, Attachment D (i.e., no additional alternative determination necessary).

1)    41 acres of North Gypsum Stack Lined Top Gradient

2)    Remainder of North Gypsum Stack Top Gradient (below lined AHPs)

Florida Appendix 7

C.   MOSAIC RIVERVIEW

Appendix 1 of this Consent Decree sets forth requirements for lining Phosphogypsum Stack Systems (“Stack Systems”) within five years of the Effective Date of this Consent Decree as a means of reducing or eliminating contamination migrating from such stacks. This Appendix identifies the specific Riverview Phosphogypsum Stack System components that, subject to the terms of the Consent Decree (including Paragraph 24(b) thereof), the EPA and FDEP accept as either meeting the liner design standards of Appendix 1, Attachment C, Section VI, or being an acceptable alternative to those standards. This Appendix also identifies the specific Riverview Phosphogypsum Stack System components that either meet the closure design standards of Appendix 1, Attachment D, or are considered to be an acceptable alternative to the closure design standards of Appendix 1, Attachment D. The EPA and FDEP’s acceptance of Mosaic’s description of the Riverview Phosphogypsum Stack System and non-Phosphogypsum Stack System components below does not bind the EPA or the FDEP to the factual information below.

General Description

The Riverview Phosphogypsum Stack System consists of the Closed Phosphogypsum Stack (Closed Stack) and its associated system components, as well as the Northeast Phosphogypsum Stack (Northeast Stack), the Phosphogypsum Stack Expansion (Stack Expansion), the lined cooling pond system, and associated stack system components (Figure 1). Mosaic has identified other water bodies existing at Riverview that are not part of the Phosphogypsum Stack System.

The Closed Stack no longer receives Phosphogypsum and, therefore, is exempt from the liner requirements. The Closed Stack-associated components include a lined auxiliary holding pond on top of the Closed Stack (Figure 1).

The Northeast Gypsum Stack was constructed with an 18-inch thick compacted bottom clayey soil liner that predated the Florida Phosphogypsum Management Rule, and at the time was deemed to be adequately protective and approved by FDEP as such. The Stack is contemplated to be constructed in phases. Its current elevation is the maximum for the existing stage, and therefore the Stack is not currently actively used for Phosphogypsum disposal. It currently is used only for Process Wastewater management.

The lined Stack Expansion is constructed south of and extends on top of the south slope of the Northeast Stack. When the Stack Expansion reaches the crest elevation of the Northeast Stack, the Northeast Stack top area will be lined with a 60-mil liner and the Expanded Phosphogypsum Stack (consisting of the combined Stack Expansion and lined vertical expansion atop the Northeast Stack) will be raised to the final design elevation.

The Stack Expansion and Expanded Stack-associated components include a lined cooling pond system. The HDPE-clay composite and/or HDPE/compacted gypsum inverted composite lined

Florida Appendix 7

cooling pond system consists of a lined Cooling Pond south of the Stack Expansion and a 32-acre cooling pond adjacent to the chemical facility. In addition, a 15-acre Lime Sludge Area with a bottom clayey soil liner (formerly part of the cooling pond) receives seepage but is currently not actively used for process water storage and as such installation of a planned HDPE inverted composite liner in this area has been deferred. The Lime Sludge Area will be lined with an inverted composite liner (80-mil HDPE covered with 2 feet of compacted gypsum) prior to incorporating it into a future Phosphogypsum Stack expansion and/or the Cooling Pond (Figure 1) and, in any event, within 5 years of the Effective Date. The slopes below Elevation 140 feet (NGVD) and the toe swale on the north, east and west walls of the Northeast Stack are closed. The toe swale has a grassed soil-covered 40-mil HDPE liner, and the stack slopes have a grassed soil cover.

Two triangular areas located on the west side of the Stack Expansion were originally a part of the main Cooling Pond, but were later closed and removed from the stack system watershed.

Soil Bentonite Cut-Off Walls

Northeast Phosphogypsum Stack

The Northeast Phosphogypsum Stack has a 2.5-foot wide slurry wall that was keyed 3 feet into the underlying clayey deposit of the Hawthorn Group at typical depths of 10 to 15 feet below natural grade to control lateral seepage from the stack. The location of the slurry wall is designated by the green line in Figure 1.

Phosphogypsum Stack Expansion

The Phosphogypsum Stack Expansion, which was constructed mostly within the northern compartments of the former 238-acre cooling pond, is enclosed by the 2.5-foot wide slurry wall that was constructed along the perimeter dike crest of the original 238-acre cooling pond. The slurry wall was keyed 3 feet into the underlying clayey deposit of the Hawthorn Group at typical depths of 10 to 15 feet below natural grade. The location of the slurry wall is designated by the green line in Figure 1.

Cooling Pond

The northern part of the Cooling Pond (including the Lime Sludge Area which is not currently actively used for process water storage but receives seepage from the stack system), was constructed mostly within the southern compartments of the former 238-acre cooling pond, and is enclosed by the 2.5-foot wide slurry wall that was constructed along the perimeter dike crest of the original 238-acre cooling pond. The slurry wall was keyed 3 feet into the underlying clayey deposit of the Hawthorn Group at typical depths of 10 to 15 feet below natural grade. The location of the slurry wall is designated by the green line in Figure 1.

Closed Phosphogypsum Stack

The Closed Phosphogypsum Stack has a 2.5-foot wide slurry wall along its north and west boundaries that was keyed 3 feet into the underlying clayey deposit of the Hawthorn Group at typical depths of 10 to 15 feet below natural grade. The location of the slurry wall is designated by the green line in Figure 1.

Florida Appendix 7

Synthetic and Clay Liners

Northeast Gypsum Stack

The Northeast Gypsum Stack, which was constructed prior to enactment of the Phosphogypsum Management Rule in the State of Florida (i.e., Rule 62-673 Florida Administrative Code), was constructed with an 18-inch thick compacted bottom clayey soil liner installed in 6-inch lifts for control of vertical seepage, with measured saturated hydraulic conductivities less than 1.0x10-8 cm/sec. A series of lateral drains were installed above the bottom clayey soil liner at the base of the gypsum stack along with a sand blanket drain near the toe to collect stack seepage. A toe drain was installed during closure of the toe swale to collect all seepage in the stack seepage collection concrete sump for pumping to the cooling pond

Phosphogypsum Stack Expansion

The Phosphogypsum Stack Expansion has: (i) an inverted composite liner system at its base consisting of an 80-mil high density polyethylene (HDPE liner) and 2 feet of compacted gypsum placed over the geomembrane with a saturated hydraulic conductivity less than 1.0x10-4 cm/sec; and (ii) a 60-mil HDPE liner placed on the south slope of the Northeast Stack currently installed to an elevation of approximately 157 feet (NGVD) that will be extended upslope in phases up to the crest of the Northeast Gypsum Stack.

32-Acre Cooling Pond

The 32-acre cooling pond has an inverted composite liner system consisting of an 80-mil HDPE liner and 2 feet of compacted gypsum cover with a saturated hydraulic conductivity of less than 1.0x10-4 cm/sec.

Cooling Pond

With the exception of an approximately 15-acre lime sludge area that has a compacted clay liner at its base, the northern portion of the cooling pond has an inverted composite liner system consisting of an 80-mil HDPE liner and 2 feet of compacted gypsum cover with a saturated hydraulic conductivity of less than 1.0x10-4 cm/sec. The southern portion of the cooling pond has a composite liner system consisting of an 80-mil HDPE liner underlain by a 12-inch thick compacted clay liner with a saturated hydraulic conductivity of less than 1.0x10-7 cm/sec.

Closed Phosphogypsum Stack

The Closed Phosphogypsum Stack has a grassed soil cover over its side slopes and a grassed soil cover over the 40-mil HDPE liner installed atop the southern 10-acre area of the stack top grade. The only area atop the stack not covered with soil and grass is the 80-mil HDPE-lined auxiliary holding pond situated atop the Closed Phosphogypsum Stack (Figure 1).

Lined Floating Ditch

The “Lined Floating Ditch” connecting the chemical plant to the lined 32-acre cooling pond was lined by Mosaic in 2011 (pursuant to a plan approved by FDEP) with an 80-mil HDPE liner and completely covered with 6-inch concrete fabriform. The HDPE liner was tied into the 32-acre cooling pond liner (Figure 1).

Florida Appendix 7

Liner Requirements for Specific Components of the Stack System and for Other Water Features

The following components or former components generally designated by red lines in Figure 2 of Mosaic’s Riverview Stack System are not subject to the lining requirements of Appendix 1, Attachments C and D, as long as they do not hereafter receive Process Wastewater or Phosphogypsum.

1) Northeast Stack Closed Slopes below El 140 feet (NGVD) on the north, east and west sides, and Northeast Stack Slopes above El 140 ft (NGVD) on the north, east and west sides that currently are scheduled to be closed in 2016.

2) Closed Phosphogypsum Stack (except for lined Auxiliary Holding Pond).

3) Closed Triangular Areas West of the Stack Expansion.

4) North Stormwater Pond

5) Staging Area

The following components of Mosaic’s Riverview Stack System designated in purple in Figure 3 have existing engineered seepage control features that, as installed, either meet the liner design standards of Appendix 1, Attachment C, Section VI or are considered by EPA and FDEP to be environmentally protective and thus considered to be an acceptable alternative to the liner design standards of Appendix 1, Attachment C, Section VI (i.e. no additional equivalency determination necessary).

1) Phosphogypsum Stack Expansion (including lined South Slope of Northeast Stack below Elevation 157 ft (NGVD))

2) Lined 32-Acre Cooling Pond

3) Lined Cooling Pond (with the exception of 15-acre Lime Sludge Area)

4) Lined Auxiliary Holding Pond

5) Lined Floating Ditch

6) Crescent Pond (lined sump)

The 15-Acre Lime Sludge Area designated by dark blue lines in Figure 4 does not fully conform to the liner design standards set forth in Appendix 1, Attachment C, Section VI, but once Mosaic implements the 15-Acre Lime Sludge Area project as set forth in Appendix 6 (RCRA Project Narrative & Compliance Schedule), it will have additional seepage control features that, when installed, will meet or exceed the liner design standards of Appendix 1, Attachment C, Section VI.

The following clayey soil lined component of Mosaic’s Riverview Stack System designated by dark blue lines in Figure 4 does not fully conform to the liner design standards of Appendix 1, Attachment C, Section VI.

Supplemental Environmental Project Description

As the Supplemental Environmental Project (SEP) required under Paragraph 39 of this Consent Decree, Mosaic shall implement the following project to mitigate and prevent certain potential environmental impacts associated with seepage emanating from areas abutting closed components of the Phosphogypsum Stack System at the facility formerly owned and operated by Mulberry Phosphates Inc., located in Mulberry, Florida (the “Mulberry Facility”).

Mosaic’s performance and satisfactory completion of this project shall be as determined based on inspection and project oversight to be provided by the Florida Department of Environmental Protection (Department). Based on the Department’s review of options for eliminating or preventing the seepage emanation discussed herein, the Department believes the value of this SEP to the State of Florida is in excess of $1,200,000. Mosaic has previously voluntarily agreed, pursuant to Department Contract No. EXC005, to undertake closure activities on behalf of the Department at the Mulberry Facility. The project described herein is not addressed by existing contracts or agreements between Mosaic and the Department.

I.    Project Description:

Following closure of the South Cooling Pond (“SCP”) of the Mulberry Phosphogypsum Stack System, rainfall infiltration in an abutting parcel of land caused lateral seepage of historically contaminated ground water to rise and emanate from the ground surface in a location just east of the at the northeast corner of the closed SCP. Such contaminated ground water, once emanating at the ground surface, would no longer be captured by the buried collection drains constructed for closure of the Mulberry Facility, resulting in an otherwise preventable source of nutrients and other surface water pollutants in the Alafia River and Tampa Bay watersheds. In order to mitigate and prevent potential contamination of surface water runoff that would otherwise be discharged through the Mulberry Facility’s NPDES permitted outfall, the following tasks will be performed by Mosaic:

1. Perform engineering services (and related permitting, administrative, and other tasks) for site investigations, basic and detailed design, construction QA/QC, construction inspection, and certification of the completed works

2. Provide engineering staff to perform onsite project construction management.

3. Following the Department’s approval of the basic and detailed designs under this SEP, Mosaic shall then commence construction activities under this SEP as follows:

a. Install an additional underdrain system, including a seepage conveyance system to intercept and collect impacted seepage that would otherwise emanate from the ground surface as described above.

b. Provide earthen fill and re-grade the impacted construction area to meet the corresponding approved design grade.

c. Install an HDPE liner and protective cover at the northeast corner of the SCP, to design grade, that would be tied into the existing SCP HDPE liner, to control infiltration in this area.

d. Perform limited cut/fill in the adjacent area to match the design grade, promote positive drainage of stormwater away from the SCP and minimize rainfall infiltration that would affect groundwater levels and otherwise contribute to the referenced groundwater seepage.

4. Perform hydraulic calculations and reconfigure (if needed in accordance with the detailed design) Outfall 001F, and the associated conveyance structure to meet design flow requirements.

5. Re-grass and provide maintenance as may be needed to establish a stabilized vegetative cover for the disturbed project construction area, for a minimum of nine months from the end of the associated construction activities.

II.  Environmental Benefit:

Completion of the above tasks are expected to mitigate and prevent future contamination to surface water runoff with nutrients and other contaminants that would otherwise cause pollutions of stormwater runoff within the Alafia River and Tampa Bay contributing watersheds.

III. Performance Schedule:

Within 90 days from the Effective Date of this Consent Decree, Mosaic will finalize a work plan and schedule to implement the project outlined above for the Department’s review and approval. Such schedule shall include a milestone for the Department’s separate approval of detailed design plans, prior to Mosaic’s commencement of installation for the additional underdrain system under this SEP. Such schedule shall provide for the completion of the tasks inSection I.1 - I.4 within 1.5 years of the Effective Date of this Consent Decree.

Following the Department’s approval of such final work plan, Mosaic shall implement the work plan in accordance with the design, associated specifications, and the schedule incorporated therein. Any changes required to the work plan, or its implementation schedule shall be agreed upon by Mosaic and the Department. Within 90 Days of completion of the tasks in Section I.1 - I.4, Mosaic will provide the Department with as-built construction drawings and a Certification of Construction Completion for the works under this SEP.
