2 Request for Proposals Deer Creek Power Plant and Switch Yard Maintenance Provo River Water Users Association BACKGROUND The mission statement of the Provo River Water Users Association (Association) is: The Association delivers Provo River Project water in a safe, efficient, and economical manner for the benefit of its shareholders and those they serve. With integrity, the Association preserves and protects the quality of its resources through knowledgeable, dedicated, and innovative employees. The Provo River Project (PRP) was planned and implemented during the 1930s and 1940s by the United States Bureau of Reclamation (Reclamation). The Association was established in 1935 to oversee the operation and maintenance of the Deer Creek division of the PRP. The PRP obtains water supplies from the Provo, Weber, and Duchesne River systems. The Association provides water to 20 shareholders which serve agricultural, municipal and industrial users. The Association manages, operates and maintains land interests and facilities in Wasatch, Summit, Duchesne, Utah, and Salt Lake Counties. In meeting its water delivery obligations, the Association coordinates water supply and conveyance needs with Reclamation, Central Utah Water Conservancy District, Weber River Water Users Association, Utah Division of Water Rights, and others. Deer Creek Dam and outlet works were placed into service in The Deer Creek Power Plant was constructed in 1958 and consists of two 2,475 kw generators. Since the plant was placed in operation, the plant has had an average power generation of over 25.8 million kwh per year. The 4.95 megawatt power plant is part of the Western Area Power Administration power system and much of the power generated is delivered to Utah cities. Additional information regarding the Association may be found on the Association s website at A. Scope of Services Provide maintenance services to facilitate operation of the Deer Creek Dam Power Plant and Switch Yard. Exhibit A contains a summary of activities required and the anticipated frequency of each activity to meet Bureau of Reclamation requirements for the Deer Creek Power Plant. Internal cost estimates indicate that an average of $50,000 per year of expenditure will be required to complete the activities. A budget coordination meeting will be held annually to discuss the upcoming requirements for the next year to allow for budgeting of funds. Project Location: Deer Creek Power Plant is located at the base of Deer Creek Dam in Provo Canyon at approximately mile post 17 on US 189. See attached Map. 2
