Organization, Consolidation and Presentation of Financial Statements [Abstract]
General	1. General
	Description of Business and Basis of Presentation
	SunCoke Energy Partners, L.P., (the "Partnership"), is a Delaware limited partnership formed in July 2012 which manufactures coke used in the blast furnace production of steel. On January 24, 2013, we completed the initial public offering ("IPO") of our common units representing limited partner interests. In connection with the IPO, we acquired from SunCoke Energy, Inc. ("SunCoke"), a 65 percent interest in each of Haverhill Coke Company LLC ("Haverhill") and Middletown Coke Company, LLC ("Middletown") and the cokemaking facilities and related assets held by Haverhill and Middletown. SunCoke owns the remaining 35 percent interest in each of Haverhill and Middletown. SunCoke, through its subsidiary, owns a 55.9 percent partnership interest in us and all of our incentive distribution rights and indirectly owns and controls our general partner, which holds a 2 percent general partner interest in us. On August 30, 2013, the Partnership completed its acquisition of the assets and business operations of Lakeshore Coal Handling Corporation, a coal handling and blending service provider. See Note 3.
	The Combined Financial Statements for periods prior to the IPO are the results of SunCoke Energy Partners' Predecessor (the "Predecessor") and were prepared using SunCoke's historical basis in the assets and liabilities of the Predecessor, and include all revenues, costs, assets and liabilities attributed to the Predecessor after the elimination of all significant intercompany accounts and transactions. The Consolidated Financial Statements for the period after the IPO pertain to the operations of the Partnership.
	The Predecessor participated in centralized financing and cash management programs not maintained at the Predecessor level for periods prior to the IPO. Accordingly, none of SunCoke’s cash or interest income for periods prior to the IPO has been assigned to the Predecessor in the Combined Financial Statements. Advances between the Predecessor and SunCoke that are specifically related to the Predecessor have been reflected in the Combined Financial Statements. Transfers of cash to and from SunCoke’s financing and cash management program are reflected as a component of parent net equity on the Combined Balance Sheets.
	Effective July 26, 2011, SunCoke allocated $225.0 million of debt and related debt issuance costs to the Predecessor. In connection with this allocation, interest expense was also allocated to the Predecessor. Prior to July 26, 2011, SunCoke did not have any external debt, and no debt or interest expense was allocated to the Predecessor. See Note 9.
	Quarterly Reporting
	The accompanying Combined and Consolidated Financial Statements included herein have been prepared in conformity with GAAP for interim reporting. Certain information and disclosures normally included in financial statements have been omitted pursuant to the rules and regulations of the Securities and Exchange Commission ("SEC"). In management's opinion, all adjustments (which include only normal recurring adjustments) necessary for fair presentation of the results of operations, financial position and cash flows for the periods presented have been made. The results of operations for the period ended September 30, 2013 are not necessarily indicative of the operating results for the full year.
	Recently Issued Pronouncements
	There are no recently issued accounting standards which are not yet effective that the Partnership believes would materially impact the Combined and Consolidated Financial Statements.

Initial Public Offering and Related Party Transactions [Abstract]
Initial Public Offering and Related Party Transactions	2. Initial Public Offering and Related Party Transactions
	Initial Public Offering
	On January 23, 2013, in anticipation of the closing of the IPO, we entered into a contribution agreement with Sun Coal & Coke, a subsidiary of SunCoke, and our general partner (the "Contribution Agreement"). Pursuant to the Contribution Agreement, upon the closing of the IPO on January 24, 2013, Sun Coal & Coke contributed to us an interest in each of Haverhill and Middletown which resulted in our owning a 65 percent interest in each of Haverhill and Middletown. In exchange, our general partner continued to hold a 2.0 percent general partner interest in us and we issued to our general partner incentive distribution rights ("IDRs") in us. We also issued to Sun Coal & Coke 2,209,697 common units and 15,709,697 subordinated units. The 35 percent interest in each of Haverhill and Middletown retained by Sun Coal & Coke is recorded as a noncontrolling interest of the Partnership.
	In conjunction with the closing of the IPO, we sold 13,500,000 common units, representing a 42.1 percent partnership interest, to the public at an initial public offering price of $19.00 per common unit. Gross proceeds from the offering were approximately $256.5 million and net proceeds were approximately $231.8 million after deducting underwriting discounts and offering expenses of $24.7 million, $6.0 million of which were paid by SunCoke in 2012 and reimbursed by us upon the closing of the IPO. We assumed and repaid $225.0 million of SunCoke's term loan debt and we retained $67.0 million for environmental capital expenditures of Haverhill and Middletown, $12.4 million for sales discounts related to tax credits owed to customers of Haverhill, and $39.6 million to replenish our working capital. We used a portion of the net proceeds from the IPO and the concurrent issuance and sale of senior notes discussed below to make a distribution of $33.1 million to SunCoke to, in effect, reimburse SunCoke for expenditures made during the two-year period prior to the IPO for the expansion and improvement of certain assets, an interest in which SunCoke contributed to us in connection with the IPO pursuant to the Contribution Agreement described above.
	Concurrent with the closing of the IPO, we and SunCoke Energy Partners Finance Corp., a Delaware corporation and a wholly owned subsidiary of ours, as co-issuers, issued $150.0 million aggregate principal amount of 7.375 percent senior notes ("Partnership Notes") due 2020 in a private placement to eligible purchasers. The Partnership Notes are the senior unsecured obligations of the co-issuers and are guaranteed on a senior unsecured basis by each of our existing and certain future subsidiaries other than SunCoke Energy Partners Finance Corp. We received net proceeds of approximately $146.3 million, net of debt issuance costs of $3.7 million, from the offering of the Partnership Notes. We also incurred $2.2 million of debt issuance costs related to entering into a revolving credit facility. See Note 9.
	Omnibus Agreement
	In connection with the closing of the IPO, we entered into an omnibus agreement with SunCoke and our general partner that addresses certain aspects of our relationship with them, including:
	Business Opportunities. We have preferential rights to invest in, acquire and construct cokemaking facilities in the United States and Canada. SunCoke has preferential rights to all other business opportunities.
	Potential Defaults by Coke Agreement Counterparties. For a period of five years from the closing date of the IPO, SunCoke has agreed to make us whole (including an obligation to pay for coke) to the extent (i) AK Steel exercises the early termination right provided in its Haverhill coke sales agreement, (ii) any customer fails to purchase coke or defaults in payment under its coke sales agreement (other than by reason of force majeure or our default) or (iii) we amend a coke sales agreement's terms to reduce a customer's purchase obligation as a result of the customer's financial distress. We and SunCoke will share in any damages and other amounts recovered from third parties arising from such events in proportion to our relative losses. During the third quarter of 2013, SunCoke, through the general partner, made a capital contribution of $0.6 million to us as a result of scaled back production.
	Environmental Indemnity. SunCoke will indemnify us to the full extent of any remediation at the Haverhill and Middletown cokemaking facilities arising from any environmental matter discovered and identified as requiring remediation prior to the closing of the IPO. SunCoke contributed $67 million in satisfaction of this obligation, at the closing date of the IPO, from the proceeds of the IPO. If, prior to the fifth anniversary of the closing of the IPO, a pre-existing environmental matter that was discovered either before or after the closing of the IPO is identified as requiring remediation, SunCoke will indemnify us for up to $50 million of any such remediation costs (we will bear the first $5 million of any such costs).
	Other Indemnification. SunCoke will fully indemnify us with respect to any tax liability arising prior to or in connection with the closing of the IPO. Additionally, SunCoke will either cure or fully indemnify us for losses resulting from any material title defects at the properties owned by the entities acquired in connection with the closing of the IPO, to the extent that those defects interfere with or could reasonably be expected to interfere with the operations of the related cokemaking facilities. We will indemnify SunCoke for events relating to our operations except to the extent that we are entitled to indemnification by SunCoke.
	License. SunCoke has granted us a royalty-free license to use the name “SunCoke” and related marks. Additionally, SunCoke has granted us a non-exclusive right to use all of SunCoke's current and future cokemaking and related technology. We have not paid and will not pay a separate license fee for the rights we receive under the license.
	Expenses and Reimbursement. SunCoke will continue to provide us with certain general and administrative services, and we will reimburse SunCoke for all direct costs and expenses incurred on our behalf and a portion of overhead costs and expenses attributable to our operations. Additionally, we paid all fees in connection with our senior notes offering and our revolving credit facility and have agreed to pay all additional fees in connection with any future financing arrangement entered into for the purpose of replacing the credit facility or the senior notes.
	So long as SunCoke controls our general partner, the omnibus agreement will remain in full force and effect unless mutually terminated by the parties. If SunCoke ceases to control our general partner, the omnibus agreement will terminate, but our rights to indemnification and use of SunCoke's existing cokemaking and related technology will survive. The omnibus agreement can be amended by written agreement of all parties to the agreement, but we may not agree to any amendment that would, in the reasonable discretion of our general partner, be adverse in any material respect to the holders of our common units without prior approval of the conflicts committee.
	Allocated Expenses
	Allocated expenses from SunCoke for general corporate and operations support costs totaled $4.1 million and $12.2 million for the three and nine months ended September 30, 2013, respectively, and $5.3 million and $15.2 million for the three and nine months ended September 30, 2012, respectively. These costs include legal, accounting, tax, treasury, engineering, information technology, insurance, employee benefit costs, communications, human resources, and procurement. Corporate allocations for periods subsequent to the IPO were recorded based upon the omnibus agreement.
	Parent Net Equity
	Net transfers to parent are included within parent net equity within the Combined Financial Statements for periods prior to the IPO. The components included intercompany dividends, cash pooling and general financing activities, cash transfers for capital expenditures and corporate allocations, including income taxes.

Business Combinations [Abstract]
Acquisition	3. Acquisition
	On August 30, 2013, the Partnership completed its acquisition of the assets and business operations of Lakeshore Coal Handling Corporation ("Lakeshore"), now called SunCoke Lake Terminal LLC ("Lake Terminal") for $28.6 million. Prior to the acquisition, the entity that owns SunCoke's Indiana Harbor cokemaking operations was a customer of Lakeshore and held the purchase rights to Lakeshore. Concurrent with the closing of the transaction, the Partnership paid $1.8 million to DTE Energy Company, the third party investor owning a 15 percent interest in the entity that owns Indiana Harbor in consideration for assigning its share of the Lake Terminal buyout rights to the Partnership. The Partnership recognized this payment in selling, general, and administrative expenses on the Consolidated Statement of Income during the period.
	Located in East Chicago, Indiana, Lake Terminal does not take possession of coal but instead derives its revenue by providing coal handing and blending services to its customers on a per ton basis. Lake Terminal has and will continue to provide coal handling and blending services to SunCoke's Indiana Harbor cokemaking operations. In September 2013, Lake Terminal and Indiana Harbor entered into a new 10 year contract with terms equivalent to those of an arm's-length transaction. The Partnership intends to maintain Lake Terminal’s current operations and retain existing staff. The results of Lake Terminal have been included in the Consolidated Financial Statements since the acquisition date. The Partnership recognized plant, property, and equipment at the fair value of $25.9 million and inventory of $2.7 million in exchange for the $28.6 million of consideration paid. No goodwill was recorded as a result of this acquisition.
	The acquisition of Lake Terminal increased revenues by $1.1 million and operating income by $0.5 million for both the three and nine months ended September 30, 2013, of which services to Indiana Harbor generated revenues of $1.0 million and operating income of $0.5 million. The acquisition of Lake Terminal is not material to the Partnership's Consolidated Financial Statements. Therefore, pro forma information has not been presented.

	Net income per unit applicable to limited partners (including subordinated unitholders) is computed by dividing limited partners’ interest in net income, after deducting the general partner’s 2.0 percent interest and incentive distributions, by the weighted-average number of outstanding common and subordinated units. Our net income is allocated to the general partner and limited partners in accordance with their respective partnership percentages, after giving effect to priority income allocations for incentive distributions, if any, to our general partner, pursuant to our partnership agreement. Net income per unit is only calculated for the Partnership subsequent to the IPO as no units were outstanding prior to January 24, 2013. Earnings in excess of distributions are allocated to the general partner and limited partners based on their respective ownership interests. Payments made to our unitholders are determined in relation to actual distributions declared and are not based on the net income allocations used in the calculation of net income per unit. For the three months ended September 30, 2013, the weighted-average number of common and subordinated units outstanding was 15,711,606 units and 15,709,697 units, respectively.
	In addition to the common and subordinated units, we have also identified the general partner interest and IDRs as participating securities and use the two-class method when calculating the net income per unit applicable to limited partners, which is based on the weighted-average number of common units outstanding during the period. Basic and diluted net income per unit applicable to limited partners are the same because we do not have any potentially dilutive units outstanding.
	The calculation of net income per unit is as follows:
			Three Months Ended September 30, 2013				Nine Months Ended September 30, 2013
			(Dollars and units in millions, except per unit amounts)
	Net income attributable to SunCoke Energy Partners, L.P. subsequent to initial public offering		$	13.7			$	41.3

	Cash Distributions
	Our partnership agreement generally provides that we will make our distribution, if any, each quarter in the following manner:
	•	first, 98 percent to the holders of common units and 2 percent to our general partner, until each common unit has received the minimum quarterly distribution of $0.41250 plus any arrearages from prior quarters;
	•	second, 98 percent to the holders of subordinated units and 2 percent to our general partner, until each subordinated unit has received the minimum quarterly distribution of $0.41250; and
	•	third, 98 percent to all unitholders, pro rata, and 2 percent to our general partner, until each unit has received a distribution of $0.47440.
	If cash distributions to our unitholders exceed $0.47440 per unit in any quarter, our unitholders and our general partner will receive distributions according to the following percentage allocations:
		Total Quarterly Distribution Per Unit Target Amount				Marginal Percentage
						Interest in Distributions

	Thereafter	above $0.681750				50	%		50	%
	In accordance with our partnership agreement, on April 23, 2013, we declared a quarterly cash distribution totaling $9.8 million, or $0.3071 per unit. In calculating this distribution, the minimum quarterly distribution was adjusted to reflect the period beginning on January 24, 2013, the closing date of the IPO, through March 31, 2013. This distribution was paid on May 31, 2013 to unitholders of record on May 15, 2013. There were no distributions declared or paid prior to this distribution.
	On July 23, 2013, the Partnership, in accordance with the partnership agreement, declared a quarterly cash distribution totaling $13.5 million, or $0.4225 per unit. The distribution was paid on August 30, 2013 to unitholders of record on August 15, 2013.
	On October 22, 2013, the Partnership, in accordance with the partnership agreement, declared a quarterly cash distribution totaling $13.9 million, or $0.4325 per unit. The distribution will be paid on November 29, 2013 to unitholders of record on November 15, 2013.
	The allocation of total quarterly cash distributions to general and limited partners is as follows. Our distributions are declared subsequent to quarter end; therefore, the table below represents total cash distributions applicable to the period in which the distributions were earned:

	Allocation of Net Income
	Our partnership agreement contains provisions for the allocation of net income to the unitholders and the general partner. For purposes of maintaining partner capital accounts, the partnership agreement specifies that items of income and loss shall be allocated among the partners in accordance with their respective percentage interest. Normal allocations according to percentage interests are made after giving effect, if any, to priority income allocations in an amount equal to incentive cash distributions allocated 100 percent to the general partner.
	The calculation of net income allocated to the limited partners was as follows:
		Three Months Ended September 30, 2013				Nine Months Ended September 30, 2013
Net Income Attributable to Common Unitholders:		(Dollars in millions)

(1) Distributions exceed unitholders' interest in net income during the three months ended September 30, 2013 as distributable cash flow excludes the $1.8 million payment to DTE Energy Company, the third party investor owning a 15 percent interest in the entity that owns Indiana Harbor. Distributable cash flow also included the $0.6 million capital contribution received under the omnibus agreement.

Income Tax Disclosure [Abstract]
Income Taxes	5. Income Taxes
	The Partnership is a limited partnership and generally is not subject to federal or state income taxes. Earnings from our Middletown operations, however, are subject to a local income tax.
	The Predecessor's tax provision has been determined on a theoretical separate-return basis. Prior to June 2012, the Predecessor received federal income tax credits for coke production from the Haverhill facility that provides coke to ArcelorMittal ("Haverhill 1") and the Haverhill facility that provides coke to AK Steel ("Haverhill 2"). These tax credits, which have been computed on an annualized basis for determining our effective tax rate, were earned for each ton of coke produced and sold during the four years after the initial coke production at each facility. The eligibility to generate tax credits for coke production generally expired in March 2009 and June 2012, respectively, for the Haverhill 1 and Haverhill 2 facilities.

Commitments and Contingent Liabilities	8. Commitments and Contingent Liabilities
	The Environmental Protection Agency ("EPA") has issued Notices of Violations (“NOVs”) for the Partnership’s Haverhill cokemaking facility which stem from alleged violations of the air emission operating permits for this facility. The Partnership is working in a cooperative manner with the EPA and the Ohio Environmental Protection Agency ("OEPA") to address the allegations, and a Consent Decree among the parties was lodged in federal court in June 2013. The settlement includes a civil penalty for alleged past violations that will be paid by SunCoke. Further, the Partnership will undertake capital projects to improve reliability of the energy recovery systems and enhance environmental performance at the Haverhill facility. As a result of recent discussions with the EPA, our Predecessor spent $5 million related to these projects in 2012 and the Partnership expects to spend approximately $21 million in 2013 and an additional $39 million in the 2014 to 2016 timeframe. We retained $67.0 million of the IPO proceeds to fund these projects. See Note 2.
	The Southwest Ohio Air Quality Agency (SWOAQA) also issued an NOV to the Middletown facility in November 2012. Our Predecessor responded to the NOV by providing a carbon injection plan requested by SWOAQA, and the Partnership has updated that plan. At present, the Partnership cannot assess whether there will be a monetary penalty or any future citations, but any potential penalty will be paid by SunCoke, and we do not expect such a penalty or citations to be material to the financial position, results of operations or cash flows of the Partnership at September 30, 2013.
	The Partnership is a party to certain other pending and threatened claims. Although the ultimate outcome of these claims cannot be ascertained at this time, it is reasonably possible that some portion of these claims could be resolved unfavorably to the Partnership. Management of the Partnership believes that any liability which may arise from claims would not be material in relation to the financial position, results of operations or cash flows of the Partnership at September 30, 2013

Debt

Debt Disclosure [Abstract]
Debt	9. Debt
	With the closing of the IPO, the Partnership issued $150.0 million of Partnership Notes. The Partnership Notes have an interest rate of 7.375 percent and mature on February 1, 2020. The Partnership may redeem some or all of the Partnership Notes prior to February 1, 2016 by paying a make-whole premium. The Partnership may also redeem some or all of the Partnership Notes on or after February 1, 2016 at specified redemption prices. In addition, prior to February 1, 2016, the Partnership may redeem up to 35 percent of the Partnership Notes using the proceeds of certain equity offerings. If the Partnership sells certain of its assets or experiences specific kinds of changes in control, subject to certain exceptions, the Partnership must offer to purchase the Partnership Notes. In conjunction with the closing of the Partnership offering, we also entered into a $100.0 million revolving credit facility with a term extending through January 2018. In conjunction with these transactions, the Partnership incurred debt issuance costs of $5.9 million, $0.8 million of which was immediately expensed and was recorded in interest expense, net on the Consolidated Statement of Income as it related to the portion of the issuance that was considered a modification of the existing term loan discussed below. This credit facility was amended on August 28, 2013, increasing the total aggregate commitments from lenders to $150.0 million and now also providing for up to $100.0 million uncommitted incremental revolving capacity, subject to the satisfaction of certain conditions. We paid $0.9 million in fees related to the credit facility amendment. The fees have been included in deferred charges and other assets in the Consolidated Balance Sheet, which will be amortized over the life of the facility. As of September 30, 2013, this credit facility had letters of credit outstanding of $0.7 million, leaving $149.3 million available.
	On July 26, 2011, SunCoke entered into a credit agreement (the “Credit Agreement”) which provides for a seven-year term loan (the “Term Loan”). Borrowings under the Term Loan bear interest, at SunCoke’s option, at either (i) base rate plus an applicable margin or (ii) the greater of 1.00 percent or LIBOR plus an applicable margin. The applicable margin on the Term Loan is (i) in the case of base rate loans, 2.00 percent per annum and (ii) in the case of LIBOR loans, 3.00 percent per annum. The weighted-average interest rate for borrowings outstanding under the Term Loan during 2012 was 4.07 percent.
	Though SunCoke is the legal entity obligated to repay the Term Loan, effective July 26, 2011, SunCoke allocated $225.0 million of the Term Loan and related debt issuance costs of $5.7 million to our Predecessor. Interest expense and amortization of debt issuance costs has been allocated to our Predecessor beginning on July 26, 2011 and totaled $0.6 million for the nine months ended September 30, 2013 and $2.5 million and $7.8 million for the three and nine months ended September 30, 2012, respectively. The amount of consolidated debt attributed to the Combined and Consolidated Financial Statements may not be indicative of the actual amounts that we would have incurred had we been operating as an independent, publicly-traded partnership for periods prior to the IPO. Prior to entering into the Credit Agreement, SunCoke did not have any external debt, and no debt or interest expense was allocated to our Predecessor. On January 24, 2013, in conjunction with the IPO, we assumed and repaid the $225.0 million of the Term Loan that was allocated to us. In conjunction with the repayment, we incurred a charge of approximately $2.9 million representing the write-off of unamortized debt issuance costs and original issue discount related to the portion of the Term Loan extinguished, which is recorded in interest expense, net on the Consolidated Statement of Income.
	Haverhill and Middletown, along with other certain SunCoke subsidiaries, guaranteed certain obligations, including $400.0 million of senior notes (the “Senior Notes”) issued on July 26, 2011 by SunCoke, and were subject to certain covenants and restrictions under the Term Loan and Senior Notes entered into by SunCoke. In connection with the IPO, SunCoke entered into an amendment to their Credit Agreement and simultaneously designated Haverhill and Middletown as unrestricted subsidiaries, removing the guarantees described above.

Fair_Value_Measurements

Fair Value Disclosures [Abstract]
Fair Value Measurements	10. Fair Value Measurements
	The Partnership measures certain financial and non-financial assets and liabilities at fair value on a recurring basis. Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in the principal or most advantageous market in an orderly transaction between market participants on the measurement date. Fair value disclosures are reflected in a three-level hierarchy, maximizing the use of observable inputs and minimizing the use of unobservable inputs.
	The valuation hierarchy is based upon the transparency of inputs to the valuation of an asset or liability on the measurement date. The three levels are defined as follows:
	•	Level 1—inputs to the valuation methodology are quoted prices (unadjusted) for an identical asset or liability in an active market.
	•	Level 2—inputs to the valuation methodology include quoted prices for a similar asset or liability in an active market or model-derived valuations in which all significant inputs are observable for substantially the full term of the asset or liability.
	•	Level 3—inputs to the valuation methodology are unobservable and significant to the fair value measurement of the asset or liability.
	Non-Financial Assets and Liabilities Measured at Fair Value on a Nonrecurring Basis
	Certain assets and liabilities are measured at fair value on a nonrecurring basis; that is, the assets and liabilities are not measured at fair value on an ongoing basis, but are subject to fair value adjustments in certain circumstances (e.g., when there is evidence of impairment). At September 30, 2013, no material fair value adjustments or fair value measurements were required for these non-financial assets or liabilities.
	Certain Financial Assets and Liabilities not Measured at Fair Value
	At September 30, 2013, the estimated fair value of the Partnership's long-term debt was $155.6 million compared to a carrying amount of $149.7 million. The fair value was estimated by management based upon estimates of debt pricing provided by financial institutions which are considered Level 3 inputs. See Note 9 for additional information on our debt arrangements.

Segment Reporting [Abstract]
Business Segment Disclosures	12. Business Segment Disclosures
	The Partnership derives its revenues from the Domestic Coke and Coke Logistics reportable segments. Domestic Coke operations are comprised of cokemaking facilities, Haverhill and Middletown, located in Ohio. Both facilities use similar production processes to produce coke and to recover waste heat that is converted to steam or electricity. The coke production for these facilities is sold directly to integrated steel producers under contracts which provide for the pass-through of coal costs subject to contractual coal-to-coke yields plus an operating cost component and fixed fee component received for each ton of coke sold.
	Prior to the third quarter of 2013, Domestic Coke was the Partnership's only reportable segment. On August 30, 2013, the Partnership completed the acquisition of Lake Terminal. Located in East Chicago, Indiana, Lake Terminal has and will continue to provide coal handling and blending services to SunCoke's Indiana Harbor cokemaking facility under contract. The results of Lake Terminal are presented in the new Coal Logistics segment below.
	Overhead expenses that can be identified with a segment have been included in determining segment results. The remainder is included in Corporate and Other in 2013. The Partnership did not exist in 2012 and therefore the Predesssor had no comparable Corporate and Other expenses. Interest expense, net is also excluded from segment results. Segment assets are those assets that are utilized within a specific segment.
	The following table includes Adjusted EBITDA, which is the measure of segment profit or loss reported to the chief operating decision maker for purposes of allocating resources to the segments and assessing their performance:
			Three Months Ended September 30, 2013

	Total segment assets		$	903.8	$	30	$	29		$	962.8
	The Partnership evaluates the performance of its segments based on segment Adjusted EBITDA, which is defined as earnings before interest, taxes, depreciation, depletion and amortization (“EBITDA”) adjusted for sales discounts. EBITDA reflects sales discounts included as a reduction in sales and other operating revenue. The sales discounts represent the sharing with customers of a portion of nonconventional fuels tax credits, which reduce our income tax expense. However, we believe our Adjusted EBITDA would be inappropriately penalized if these discounts were treated as a reduction of EBITDA since they represent sharing of a tax benefit that is not included in EBITDA. Accordingly, in computing Adjusted EBITDA, we have added back these sales discounts. EBITDA and Adjusted EBITDA do not represent and should not be considered alternatives to net income or operating income under GAAP and may not be comparable to other similarly titled measures in other businesses. Management believes Adjusted EBITDA is an important measure of the operating performance of the Partnership’s net assets.
	We believe Adjusted EBITDA is an important measure of operating performance and provides useful information to investors because it highlights trends in our business that may not otherwise be apparent when relying solely on GAAP measures and because it eliminates items that have less bearing on our operating performance. Adjusted EBITDA is a measure of operating performance that is not defined by GAAP, does not represent and should not be considered a substitute for net income as determined in accordance with GAAP. Calculations of Adjusted EBITDA may not be comparable to those reported by other companies.
	Set forth below is additional detail as to how we use Adjusted EBITDA as a measure of operating performance, as well as a discussion of the limitations of Adjusted EBITDA as an analytical tool.
	Operating Performance. Our management uses Adjusted EBITDA in a number of ways to assess our consolidated financial and operating performance, and we believe this measure is helpful to management in identifying trends in our performance. Adjusted EBITDA helps management identify controllable expenses and make decisions designed to help us meet our current financial goals and optimize our financial performance while neutralizing the impact of capital structure on financial results. Accordingly, we believe this metric measures our financial performance based on operational factors that management can impact in the short-term, namely our cost structure and expenses.
	Limitations. Other companies may calculate Adjusted EBITDA differently than we do, limiting its usefulness as a comparative measure. Adjusted EBITDA also has limitations as an analytical tool and should not be considered in isolation or as a substitute for an analysis of our results as reported under GAAP. Some of these limitations include that Adjusted EBITDA:
	•	does not reflect our cash expenditures, or future requirements, for capital expenditures or contractual commitments;
	•	does not reflect changes in, or cash requirement for, working capital needs;
	•	does not reflect our interest expense, or the cash requirements necessary to service interest on or principal payments of our debt;
	•	does not reflect certain other non-cash income and expenses;
	•	excludes income taxes that may represent a reduction in available cash; and
	•	includes net income attributable to noncontrolling interests.
	Below is a reconciliation of Adjusted EBITDA (unaudited) to net income, which is its most directly comparable financial measure calculated and presented in accordance with GAAP:

	(1) Distributions exceed unitholders' interest in net income during the three months ended September 30, 2013 as distributable cash flow excludes the $1.8 million payment to DTE Energy Company, the third party investor owning a 15 percent interest in the entity that owns Indiana Harbor. Distributable cash flow also included the $0.6 million capital contribution received under the omnibus agreement.
