We have made a concerted and consistent effort to adhere to and advance the concept of "Indian Preference," which can be demonstrated by the following statistics: 1977 1984 --------- -------- Total Number of Indian Employees 312 (49%) 696 (65.7%) In addition, APS has made a significant contribution to the upward mobility of qualified Indians in numerous classifications, as evidenced by the following information: 1977 1984 --------- -------- Maintenance Mechanics 11 (41%) 66 (52%) Journeyman Classification 20 (19%) 108 (45%) Auxiliary Operators 25 (61%) 50 (91%) Control Operators 6 (35%) 15 (63%) First Line Supervisors 3 (10%) 32 (36%) APS is committed to the continued pursuit of preferential employment of Indians at the Four Corners Generating Station pursuant to the provisions of this Lette Agreement, subject to any limitations contained in applicable provisions of the Labor Agreement in effect between APS and the I.B.E.W. Local Union No. 387. Qualifications for employment and promotion shall be determined by APS. In all instances, qualifications for positions will be job-related and nondiscriminatory, and will be reviewed on an ongoing basis to ensure validity and relevance of such qualifications. A list of the current positions is attached as Appendix A. In support of this commitment, APS proposes the following program to enhance the employment status of Indians: - 41 - The Honorable Peterson Zah March 8, 1985 Page 2 1. Employment Preference A. Subject to meeting its established minimum qualifications, APS shall give preference in hiring and promotion to Indians whose qualifications are equal to or better than those of non-Indian Candidates. B. When hiring temporary student employees, preference will be given to Indians, where qualified. 2. Training Training Programs shall be designed and implemented where cost effective to enable the Four Corners Generating Station to meet its manpower requirements. With respect to training courses which may be implemented at the Four Corners Generating Station in the future, preferential selection will be extended to Indian candidates. A. Training courses APS has conducted at the Four Corners Generating Station in the past, including the following: Auxiliary Operator Power Plant Fundamentals Basic Mechanics Safety Training Control Operator Supervisory Skills Lubeman Management Training Mobile Equipment Training Water Analyst Welder B. With respect to training programs, APS will encourage its Indian employees to take advantage of such opportunities to enhance their upward mobility potential. 3. Promotions, Transfers and Work Force Reduction A. Performance Review: Preference shall be given to Indian employees with respect to reductions in force for performance review positions subject to job requirements, employee qualifications, and past work history. Should a transfer be desired by performance review employees and required by APS, preference shall be given to the best qualified Indian employee as provided in Paragraph 1 hereof, depending on the position into which the transfer is sought. B. Bargaining Unit: With respect to bargaining unit positions involved in promotions, transfers, reductions in force and - 43 - The Honorable Peterson Zah March 8, 1985 Page 3 recalls, seniority establishing by the Labor Agreement will be the deciding factor where qualifications and physical fitness are substantially equal. However, if not in conflict with such Labor Agreement, such seniority shall first be applied to the Indian applicants or candidates. If after APS has met its preference obligations and no Indians are available, then seniority may be applied among the non-Indian applicants or candidates. 4. Grievance Procedure: A. Bargaining unit employees will utilize the Grievance Procedure agreed to between APS and I.B.E.W. Local Union No. 387. B. Performance review employees will utilize the established APS Equity Procedure to resolve grievances. C. APS shall make a good faith effort to negotiate with the I.B.E.W. to include a provision in the Labor Agreement requiring the inclusion of Navajo employees in the grievance procedure. 5. Hiring Notification, Recruiting and Advertising A. When it is necessary for APS to hire outside applicants to fill job openings, APS shall utilize Navajo personnel in its recruitment process and shall provide notification to the Navajo Nation and other agencies as indicated below. Such notifications shall state that preference will be given to qualified American Indians as provided in Paragraph 1 hereof, depending on the position being filled: (i) Director of the Office of Navajo Labor Relations ("ONLR") in Window Rock, Arizona, (ii) BIA Employment Assistance Offices in Window Rock and Farmington, (iii) Farmington Inter-Tribal Organization, (iv) Denver National Indian Employment Resource Center, and - 44 - The Honorable Peterson Zah March 8, 1985 Page 4 B. When advertising is required for an outside hire, the following newspapers will be utilized in addition to others as appropriate: (i) Navajo Times, Window Rock, Arizona (ii) Gallup Independent, Gallup, New Mexico (iii) Farmington Daily Times, Farmington, New Mexico (iv) Lake Powell Chronicle, Page, Arizona. C. APS will recruit Indian candidates at Northern Arizona University, University of Arizona, Arizona State University, University of New Mexico, and New Mexico State University, in addition to other educational institutions as appropriate. 6. Reporting The Four Corners Power Plant will report manpower and furnish a statistical breakdown by race of all new hires, promotions and transfers, on a quarterly basis to the ONLR. 7. Contractor/Hiring Preference A. Contractors will be required to agree that Indian preference will apply to employment at the Four Corners Generating Station. Contractors will be instructed to notify the Union Hall that Indians, where qualified and available, are to be dispatched before non-Indians. B. Contractors and APS shall not be responsible for dispatching of personnel by the Union Hall, but only for the proper notification of the Union Hall. Problems, if any, in dispatching, shall be addressed by the Navajo Nation to the Union Hall, rather than to contractors or APS. The parties shall use their best efforts to insure that job completion, productivity and/or costs will not be impacted by dispatching problems. C. Contractors will be instructed by APS to notify the ONLR as soon as practical (and to provide copies of such notice to APS) of anticipated manpower requirements and qualifications needed before placing a call to the Union Hall. - 45 - The Honorable Peterson Zah March 8, 1985 Page 5 D. Contractors will be required to report manpower monthly to ONLR (and provide copies of such reports to APS), indicating numbers of Indians and non-Indians personnel by job classification. 8. Contractor/Vendor Preference APS shall give contracting preference to members of the Navajo Nation and Navajo firms, certified by the Commerce Department of the Navajo Nation, in all contract work to be performed on leased lands including but not limited to construction contracts, procurement and personal service contracts, provided that the requisite experience and competence to perform such contractual work and procure material and equipment of comparable quality and price in accordance with standard practices in the electric utility industry can be demonstrated. Subject to the foregoing, where two or more bids are received by APS for a given item of contractual work and where one of such bids is submitted by a member of the Navajo Nation or a certified Navajo Firm, such contract shall be awarded to such member of the Navajo Nation or Navajo firm, if their bids are equal to or less in price than the bids of non-members or uncertified firms and their qualifications are equal to or better than those of such non-members and firms. More specifically: A. APS shall extend preference to Indian contractors/vendors and where they are qualified and/or supply a quality product and are evaluated equal to or better than non-Indian contractor/vendor, the Indian contractor/vendor will be selected. B. All contractors/vendors must be qualified by APS before being placed on an approved bidders list. Qualification includes commercial and financial viability as well as product and/or service quality. C. Potential contractors/vendors should be directed to call the Four Corners Power Plant for an appointment to apply for consideration as a qualified bidder. Appointments are normally scheduled Tuesday, Wednesday, and/or Thursday 8:30 a.m. - 46 - The Honorable Peterson Zah March 8, 1985 Page 6 through 3:00 p.m. The following is a general list of products and services utilized at Four Corners: Products: Services: Boiler equipment Mobile demineralizer Turbine and auxiliary equip.

Goods and services shall be purchased on the basis of competitive bidding where practical. Invitations to bid will be issued to individuals and firms on the approved bidders list. 9. Community Programs APS will actively support community programs as they relate to the Four Corners Generating Station and Career Days/educational programs sponsored by schools located on the Navajo Reservation. These programs will be supported with printed materials, speakers, and audiovisual material as appropriate. - 47 - The Honorable Peterson Zah March 8, 1985 Page 7 10. Navajo Preference In the event the Navajo Nation secures a judgement upholding APS' right to grant "Navajo" as distinguished from "Indian" preference in employment, APS agrees thereafter to grant Navajo preference in employment in accordance with this Letter Agreement. 11. Resolution of Disputes Between Parties In the event of a claimed breached of this Letter Agreement or a dispute between the parties arising out of this Letter Agreement, at the request of either the Chairman of the Navajo Nation or the President of APS, each of the parties shall submit to a compulsory minitrial for the resolution of any such claim or dispute. The purpose of the minitrial is to inform management representatives for the parties of the theories, strengths and weaknesses of the parties' respective positions so that the parties may amicably resolve the claim or dispute at issue. A. Business representatives of each of the parties empowered to decide the issues shall attend the minitrial to be conducted for one business day within 60 days after written notice of the claim or dispute is delivered to the other party at a mutually convenient location. In addition, an individual mutually selected by counsel for the parties will attend as a "neutral advisor." B. The fees and expenses of the neutral advisor shall be borne equally by the parties. Each of the parties shall otherwise pay its own costs. C. The neutral advisor shall be provided with copies of this Letter Agreement. Neither of the parties nor anyone on its behalf shall unilaterally approach, contact or communicate with the neutral advisor after his or her selection. D. Shortly after appointment of the neutral advisor, each of the parties shall in good faith attempt to agree to produce documents requested by the other party in as expeditious a manner as possible. The production of documents shall be subject to the successful negotiation by the parties of an acceptable arrangement regarding the protection of proprietary or other confidential information. In the event that after the minitrial the parties submit their dispute to litigation as provided in Subsection I below, the parties shall in good faith attempt to agree to the entry of an appropriate protective order with respect to the documents produced. - 48 - The Honorable Peterson Zah March 8, 1985 Page 8 The neutral advisor will be required to be a party of any confidentiality agreement or protective order. E. Shortly after appointment of the neutral advisor, mutually agreed upon source material will be jointly sent to the neutral advisor to assist him/her in familiarizing him/herself with the basic issues of the case. Seven days before the minitrial is to be held, the parties shall exchange all exhibits they plan to use at the minitrial. Shortly before the scheduled minitrial, if the neutral advisor so suggests and if the parties agree, the neutral advisor may confer jointly with counsel for the parties to resolve any outstanding procedural questions. If the neutral advisor wishes to consult with the parties' technical experts on substantive issues prior or after the meeting, he/she may outline the general areas of inquiry and, on agreement by the parties, the neutral advisor may submit written questions to the parties' technical experts. F. Within three (3) days before the minitrial is to be held, the parties shall exchange and submit to the neutral advisor introductory statements which are not to be longer than ten 8-1/2" x 11" double-spaced pages. G. The presentations at the minitrial shall be informal, the time for which presentations will be equally divided between the parties. Rules of evidence will not apply. While permitted to ask clarifying questions, the neutral advisor shall not preside like a judge or arbitrator, nor have the power to limit the scope or substance of the Parties' presentations. The presentations will not be transcribed or recorded, but either of the parties may take notes of the proceedings. H. At the conclusion of the presentations and to the extent reasonable, the parties will make their business representatives available for discussions. If the parties are unable to resolve the disputes themselves based upon a good faith evaluation of the presentations, to assist the parties in further discussions, the neutral advisor will render his/her comments orally on the issues. Thereafter, the business representatives of the parties shall meet and be available for discussions at least once. I. In the event that upon conclusion of the minitrial the parties are unable to amicably resolve their disputes, each party shall be free to litigate such disputes in the courts of the United States. Litigation shall be limited to the issues considered at the minitrialan shall be conducted to the extent possible on the same terms as the minitrial. The parties agree to waive any applicable statute of limitations for three years following the minitrial defense with respect to subsequent litigation of these disputes between the parties. - 49 - The Honorable Peterson Zah March 8, 1985 Page 9 J. The advisory comments of the neutral advisor will be inadmissible for all purposes in this or any other dispute involving the parties. 12. Term The program outlined herein will be in effect for a period of not less than four years. At any time following the anniversary of the fourth year, the terms of this Letter Agreement may be reopened by either Party, and upon reaching any new agreements, this Letter Agreement shall be amended without amending the Four Corners Plant Site Leases.
