EXPLANATORY RECITALS 1.1 WHEREAS, Reclamation in the above mentioned Acts has been authorized by Congress to participate in the Southern Arizona Regional Water Management Study (SARWMS); and 1.2 WHEREAS, Reclamation has programmed funds under the General Investigative Program and the Colorado River Basin Project Act to participate in SAR WMS and seeks at least 50 percent match-of-study costs by local sponsors through direct funding or in-kind services; and 1.3 WHEREAS, a Work Plan for SAR WMS has been developed (Attachment "A"), and said Work Plan shall focus on preparing a comparative analysis of four water supply alternatives for the northwest Tucson Active Management Area (T AMA); and 1.4 WHEREAS, the Towns ofOro Valley and Marana, MDWlD, and the Pima County Flood Control District, hereinafter collectively referred to as the "Local Sponsors", seek to support and participate in said Study by providing, through in-kind services and use of consultants, a portion of the 50 percent match-of-study costs sought by Reclamation; and \ :~ , I 1.5 WHEREAS, Reclamation has been participating with entities in the northwest T AMA to study recharge and reclaimed effluent use, and a logical continuation of that effort would be for Reclamation to assist the Towns ofOro Valley and Marana, and MDWID, hereinafter collectively referred to as the "northwest T AMA water providers", in developing an analysis of water supply alternatives; and 1.6 WHEREAS, securing renewable water supplies for the northwest T AMA will accommodate planning for future development; and 1.7 WHEREAS, the Local Sponsors desire to identify end uses of effluent produced from County facilities in order to best match treatment level with product use; and 1.8 WHEREAS, Pima County Flood Control District seeks to facilitate an analysis of regional water supply alternatives that may include recharge in the floodplains of the Lower Santa Cruz River and Canada del Oro Wash; and 1.9 WHEREAS, Pima County Flood Control District and Reclamation hereby agree that contract number 01-04-U-123237-0797 will be terminated according to the provisions of that contract, and that this Agreement replaces contract number 01-04-U-123237-0797, which was entered into on July 15, 1997 by and between the Pima County Flood Control District and Reclamation. NOW, THEREFORE, in consideration of the covenants and conditions herein contained, Parties agree as follows: 2. INTRODUCTION AND PURPOSE 2.1 The purpose of this agreement ("Agreement") is to provide a framework for the joint conduct ofSARWMS, and define the obligations of the Parties relative to the Study. Reclamation provided funding in Fiscal Years 1997, 1998 and 1999, and may provide funding in Fiscal Year 2000. The General Investigation Program requires cost sharing with local sponsors. The Towns ofOro Valley and Marana, MDWID, and the Pima County Flood Control District will participate as Local Sponsors. 2.2 The purpose of SARWMS is to coordinate and integrate the planning efforts ofthe northwest T AMA water providers to develop a comprehensive water management plan for the northwest portion of the T AMA. .!. 2.3 The purpose of this Study is to develop a comparative analysis of four water supply alternatives for the northwest T AMA. A study objective includes identifying long- range needs and matching them with available and appropriate supplies, including groundwater, CAP water and effluent. 2.4 The role of Reclamation in this Study is to fund a portion of the Study, and provide project management and oversight for the Study. Reclamation will work with the , , Local Sponsors to develop a comparative analysis of four water supply alternatives for the northwest T AMA as described in Attachment "A". Because the basis for cost estimates of three of the four alternatives have already been largely completed, the emphasis of this Study will be to develop the cost estimate for the remaining water supply alternative (alternative 3, Attachment "A"). 3. SERVICES TO BE PERFORMED 3.1 The Parties hereby agree that an employee of Reclamation shall be the Project Manager, and that said Project Manager shall perform and carry out the duties and responsibilities required to accomplish the Work Plan as outlined in Attachment "A" of this Agreement. 3.2 Reclamation shall, with its staff or by contract, use appropriated funds and contributed in-kind services to complete the Work Plan as set forth in Attachment "A", to the extent that in-kind services are provided by the Local Sponsors, and Federal funds are appropriated for this purpose. 3.3 The Local Sponsors shall work with Reclamation, and shall provide guidance and information as appropriate, and review work products. 3.4 Upon completion of the Study, Reclamation shall transmit to the Local Sponsors the report as described in Attachment "A". 4. TERM OF AGREEMENT 4.1 This Agreement shall become effective upon the date an executed copy is recorded and shall remain in effect until completion of the Study report, but in no event later than June 30,2000, unless either Party terminates work pursuant to Article 11 herein. The Parties hereto anticipate that the draft Study report will be completed no later than December 31, 1999, and the final Study report will be completed no later than March 31,2000. If work is terminated pursuant to Article 11, this Agreement will terminate in ten (10) days following written notice. 5. COORDINATION AND PROGRESS REPORTS 5.1 A Study Management Team (SMT) shall be formed to oversee the development of the Study alternatives, level of detail of the Study and conformance with Study goals. The SMT shall consist of one representative from Reclamation, one from each of the Local Sponsors, one from members who qualified under the Northwest Replenishment Program, and one from members who qualify under Section 5.2 below. ~ , '" .i. 5.2 New members shall be added to the SMT if resources equaling or exceeding $100,000 are committed to the Study. These resources may be cash, in-kind services, use of consultants, or some combination thereof. The criterion for acceptability of a contribution is approval of the sponsor's governing body, where necessary, and acceptance of the contribution by Reclamation as qualifying for local matching funds for the study. Reclamation shall determine whether the contribution is acceptable based on consistency with the Work Plan (Attachment "A"). 5.3 For purposes of dis~ussion, the SMT may include more than one representative from each Project Sponsor. However, for purposes of resolving issues, only one representative from each Sponsor shall have a designated right to vote. 5.4 Each Local Sponsor shall maintain an accounting of its contributions to this Study, and shall provide an accounting to Reclamation when so requested by Reclamation. 6. STUDY FUNDING 6.1 Reclamation shall perform portions of the Work Plan as documented in Attachment "A", except that total Reclamation cost-share contributions shall not exceed 50% of the total cost of the study. The total cost-share contributions of the Local Sponsors shall, at a minimum, equal Reclamation's cost contribution to the Study. 6.2 If, during the Study term, projections of Study costs indicate that the available funds may be exceeded, Reclamation and the Local Sponsors' Study representatives shall be notified. Should the Local Sponsors or Reclamation be unable to arrange for appropriate funding or in-kind services, Study activities may be suspended until the Work Plan is reconciled with the existing funding program, or other options are identified that are acceptable to the Parties of this Agreement. 7. IN-KIND SERVICES 7.1 As determined by Reclamation, services provided by the Local Sponsors which are consistent with the Work Plan in Attachment "A" and which would otherwise be performed by Reclamation, shall be deemed to be "in-kind" services. 7.2 The value of in-kind services provided by the Local Sponsors shall be credited toward the payment of the local cost-share, as documentation is received by Reclamation that said in-kind services have been accomplished. The value of those services will generally be compared to what it would have cost Reclamation to provide the same service. .l. c 7.3 The following pre-Agreement activities qualify as local matching in-kind services, subject to adequate documentation being provided to Reclamation: ~ . a. Southern Arizona Regional Water Management Study development costs incurred by the Local Sponsors, as approved by Reclamation; t b. Activities begun or completed under the Northwest Tucson Active Management Area Replenishment Program Feasibility Study that will be used in conjunction with or are required to complete this Study, as approved by Reclamation; and c. Other activities as approved by Reclamation. 8. CHANGES AND DISPUTES 8.1 The Parties acknowledge that the schedule of activities and costs of conducting the Study may be subject to change. The Parties also acknowledge that the Work Plan may be revised as changes occur in the physical dimensions of the project plan and amendments thereto, the technical effort needed to complete the Study, and the cost of the Study. If, after consultation, the Local Sponsors and Reclamation agree that a change in the activities or costs described in the Work Plan is necessary and feasible, the Work Plan may be modified in writing to reflect these changes by written amendment to the Work Plan in Attachment "A". 8.2 If disputes arise over the provisions of, or performance under this Agreement, representatives of the Local Sponsors and Reclamation will attempt to resolve the disagreement. In the event the Parties do not reach an agreement resolving the disputed issues, any Party may amend or terminate this Agreement as provided in Article 11. 9. LIABILITY 9.1 Reclamation shall perform its obligations under this Agreement in the capacity of a Federal agency. It is neither a coventurer, agent, employee, nor representative of the Local Sponsors. The Local Sponsors assume no liability for claims or actions arising solely out of the performance of such work by Reclamation's employees or agents. 9.2 Liability of the United States resulting from the negligence of its employees shall be governed by the Federal Tort Claims Act (28 U.S.C. 2671, et. seq.). The Local Sponsors recognize that the Federal Tort Claims Act operates to provide liability coverage for the United States Government and its employees in lieu of ordinary msurance coverage. ! '" ...., 9.3 The United States shall not be liable for loss, damage, or expenses to any other Party caused by intentional and wrongful act, action, neglect, omission, or default in connection with in-kind services provided by the Local Sponsors under this Agreement. ~ .1 9.4 If a contractor is hired by Reclamation or the Local Sponsors, the Party that hired the contractor is responsible for payment for work performed, as well as liability for and resolution of contract disputes with the contractor. 10. CONTINGENT ON APPROPRIA nON OR ALLOTMENT OF FUNDS 10.1 The expenditure or advance of any money or the performance of any obligation by the United States under this Agreement shall be contingent upon appropriation or allotment of funds by Congress.

BUREAU OF RECLAMATION UNITED STATES DEPARTMENT OF INTERIOR ~:OlE~~L Phoenix Area Office 7)7/17 I- Date 1 i .=:1 1 ATTACHMENT "A" WORK PLAN SOUTHERN ARIZONA REGIONAL WATER MANAGEMENT STUDY Background Central Arizona Project (CAP) water was first introduced into the Tucson area in 1992. Problems experienced during initial deliveries have led to a reassessment of local plans for using CAP water, as well as a reassessment of the relationships among various local water providers. To date, there are no firm regional water resources plans to integrate CAP water supplies with existing supplies within the Tucson Basin. In addition, there is a need to study and possibly implement localized distribution system improvement and coordination projects. The Towns of Oro Valley and Marana, the City of Tucson, and the Metropolitan Domestic Water Improvement District are all performing separate studies of future water supply alternatives. In order to assist in the development of an overall regional plan to provide water to the Northwest Tucson area, the Bureau of Reclamation (Reclamation) is sponsoring this study, referred to as the "Southern Arizona Regional Water Management Study". Issues to be Addressed There are a number of important issues that must be considered relative to future water resources planning for the study area. These are as follows: - CAP allocations, water use methods, and requirements - CAP terminal storage facility requirements, sizing and locations - CAP service reliability and sustainability - CAP water quality - Potential for localized distribution system coordination - Aquifer recharge capabilities - Aquifer safe yields - Present and future ground water quality - Present and future water treatment costs - Environmental impacts of CAP imports, recharge and effluent reuse - Present and future delivery system infrastructure - Institutional restrictions and requirements - Public perceptions of water resource management activities , .. " Studv Activities Overview : The development and analysis of water resources management and distribution system alternatives are to be the focus of activities in this regional study. Portions of the activities discussed in this Work Plan have been performed for other studies, but not integrated into the overall plan for the study area. Relevant material will be incorporated into this study. Specific study activities will include a water supply and demand assessment; an inventory of existing and associated problems; an inventory of institutional constraints; the development and analysis of water supply alternatives; the development and analysis of distribution system operational improvement through cooperation among water providers; and the development of preliminary designs and cost estimates. Division of work will enhance a sense of ownership in the results among the study participants and will provide for cost sharing as required for Reclamation funding. CAP reliability issues need to be looked at beyond those previously considered by Reclamation. Reclamation has informed the northwest water providers that CAP reliability features may be considered for direct delivery of CAP water alternatives. Water Supply Assessment The purpose of the water supply assessment will be to consolidate knowledge about how each agency provides water to its customers; what each anticipates its present and future demands to be; and to ascertain the quantity and quality of water resources that will need to be developed in the future. The following activities will be performed in this study: - Inventory existing and historic demand, and estimate future demand - Inventory historic and existing water quality - Identify future water quality objectives for import and/or reclaimed water - Inventory existing infrastructure, and identify problems and needs - Identify operational restrictions in distribution systems - Identify overdraft areas - Estimate safe yields without artificial recharge - Identify requirements for import water (new water and/or reclaimed) - Develop task summary report Institutional Inventory The development of an inventory of institutional constraints and requirements that affects the regional management of water resources will be identified and summarized, as indicated in the following task list: .1 ~ -; - Identify Local, State and Federal Water Resources Policies, Agreements, and activities - Identify Federal project authorizations - Summarize Southern Arizona Water Rights Settlement Act of 1982 - Identify CA WCD policies and agreements - Summarize Ground Water Management Act of 1980 (A WS Rules) - Summarize Ground Water Recharge and Underground Storage Act of 1986 - Summarize Arizona groundwater replenishment district policies and agreements 1 . .. "' _ Summarize pertinent State and Federal water quality regulations - Develop task summary report Alternatives Development Several alternatives have been developed in other studies. Due to the limited financial and human resources available for this study, an initial assessment will lead to the selection of up to five alternatives for further analysis. The regulatory, financial and economic implications of implementing each alternative, as well as the benefits, will be assessed. There are a number of regional water supply issues that will be considered in shaping alternatives in the SAR WMS. These are listed below: - CAP water allocations - CAP terminal storage locations and requirements - CAP delivery costs - Impacts of direct use of CAP water on infrastructure and water quality - CAP, terminal storage, and distribution system reliability - CAP water deliveries to recharge projects - CAP water quality impacts on groundwater from recharge projects - Blended use of CAP and groundwater - Treatment plant and distribution system requirements - Effluent treatment and reuse objectives - Water conservation practices Potable water supply alternatives that are being considered include: 1. Continued use of groundwater - Under this scenario, groundwater replenishment can take place anywhere in the Active Management Area. Meets the "letter of the law" for Assured Water Supply. 2. Recharge and recovery of CAP water - This alternative was studied in depth for the Canada del Oro Project. The Lower Santa Cruz Project could provide recharge and recovery primarily for the Marana portion of a regional system. This alternative assumes that the northwest water providers want to go beyond the "letter of the law" and want to use wet water in their delivery system. 3. Direct use of CAP water from a new water treatment plant - Assumes CAP water is treated to primary drinking water standards using filtration and disinfection. Location of a water treatment plant (WTP) will be based on several factors, after the analysis of the water providers' distribution system plans has been completed. 4. Direct use of CAP water from the Hayden-Udall WTP - Assumes CAP water is treated to primary drinking water standards using filtration and disinfection at the Hayden-Udall WTP and is then delivered to the northwest water providers. This scenario represents the original planning that Tucson Water had developed. Localized Distribution System Imorovement and Cooperation Alternatives Another main purpose of this study is to develop and analyze alternatives for localized distribution system improvements, and related opportunities for cooperation among local water providers in the northwest metropolitan area. This study will result in a number of recommendations to help resolve how distribution system infrastructure improvements and cooperative agreements can assist the northwest area water providers in serving their customers and in meeting future growth requirements. Modeling and Analysis of Distribution System Alternatives The distribution system alternatives will be evaluated through the development and application of a distribution system network model. This model will have the capability of simulating pipe network deliveries to demand centers within the northwest area. Simulation output would provide information about pipe network flows, pressures, and storage volumes. The main function of the model is to size the pipeline and reservoir facilities identified in each alternative. Results of network model simulations will be presented in tabular and graphical form. Preliminary Design and Economic Analysis A cost estimate, which will include capital costs as well as operational and maintenance costs, will be performed for each alternative. This information, combined with performance related information from the network modeling and the results of the evaluation of regulatory implications, will provide the basis for the selection of a preferred alternative. Public Involvement It is unclear, at this time, whether extensive public involvement will be required. It does, however, seem appropriate to hold public meeting to present study results and conclusions. A comprehensive program to educate the public relative to all aspects of implementation of the preferred plans will be the responsibility of the northwest water providers. ~ : Environmental Studies The resources provided for the SAR WMS will not be sufficient to perform detailed environmental impact analyses. Detailed studies would be a next logical step towards the implementation of a preferred alternative. However, a preliminary study of the environmental impacts of the preferred alternatives will be performed. Strategy Proposed infrastructure information supplied by each water provider will serve as the basis for beginning to design the pipeline for direct delivery of CAP water. Information on proposed infrastructure can also be used to begin identifying potential operational coordination benefits. 1. Reclamation will develop feasibility level designs and cost estimates for the main delivery pump stations and pipelines for alternative 3 (direct use of CAP water from a new water treatment plant). 2. Each water provider, working with Reclamation, will develop feasibility level designs and cost estimates for infrastructure from the turnout off of the main pipelines. 3. Develop distribution system operational improvement/cooperation alternatives. 4. Reclamation will begin performing feasibility level designs for an "integral" reliability feature for CAP water. The above four steps will be an iterative process between Reclamation & water providers in order to optimize the design. 5. Compare total cost (Capital and O&M) of water supply alternatives 1 through 4. 6. Present results in a report. Include NEPA for TASRI.
