Scoping Summary Report – Keechelus-to-Kachess Conveyance and Kachess Drought Relief Pumping Plant Environmental Impact Statement A component of Yakima River Basin Integrated Water Resource Management Plan Yakima Project, Washington Pacific Northwest Region U.S. Department of the Interior Washington State Bureau of Reclamation Department of Ecology Pacific Northwest Region Office of Columbia River March 2014 Columbia-Cascades Area Office Mission Statements The mission of the Bureau of Reclamation is to manage, develop, and protect water and related resources in an environmentally and economically sound manner in the interest of the American public. The mission of the Department of Ecology is to protect, preserve and enhance Washington’s environment, and promote the wise management of our air, land and water for the benefit of current and future generations. Scoping Summary The Proposed Project The Bureau of Reclamation and the Washington State Department of Ecology are joint leads in preparing an environmental impact statement (EIS) for the proposed Kachess Drought Relief Pumping Plant (KDRPP) and the Keechelus-to-Kachess Conveyance (KKC) that meets the requirements of both the National Environmental Policy Act (NEPA) and the Washington State Environmental Policy Act (SEPA). Both projects are components of the Yakima River Basin Water Enhancement Project (YRBWEP) Integrated Water Resource Management Plan (Integrated Plan). The KDRPP is included in the Surface Water Storage element of the Integrated Plan and the KKC is included in the Structural and Operational Changes element of the Integrated Plan. The project-level EIS for KDRPP and KKC will tier to the March 2012, Yakima River Basin Integrated Water Resource Management Plan Final Programmatic EIS. Tiering refers to using the coverage of general matters in a broader NEPA document in a subsequent, narrower NEPA document (40 Code of Federal Regulations [CFR] 1508.28, 40 CFR 1502.20). This allows the tiered NEPA document to focus on a site-specific or project-specific proposal and its alternatives, and to concentrate solely on the issues not already addressed in the broad programmatic NEPA document. Tiering is appropriate when the analysis for the proposed action will be a specific refinement or project implementing the programmatic NEPA action. The tiered document focuses only on those issues and mitigation measures specifically relevant to the project- specific proposal but not analyzed in sufficient detail in the program-level EIS. Two separate, yet related, projects are being proposed by Reclamation and Ecology in the upcoming environmental impact statement. The proposed action for the Kachess Drought Relief Pumping Plant would provide additional water supply for municipal, domestic, and agricultural uses during drought years. The current reservoir outlet for Kachess Reservoir does not provide access to water below elevation 2,192 feet; therefore, water stored in the reservoir below that elevation is currently designated as unusable, or “inactive,” storage. Reclamation and Ecology propose to install a pumping plant at the Kachess Reservoir to allow additional water (up to 200,000 acre-feet) to be withdrawn from the reservoir below the current outlet during drought years. 1 The proposed action for the Keechelus-to-Kachess Conveyance would involve a tunnel through which water would be moved from the Keechelus Reservoir to Kachess Reservoir in order to reduce flows in the upper Yakima River to improve ecological conditions for fish and enable the storage of more runoff from the Keechelus Reservoir drainage to provide additional water supply for municipal and domestic uses, and agriculture. This project could also potentially augment flows to refill Kachess Reservoir. In addition, an alternative combining both the KDRPP and KKC will be evaluated in the EIS, as well as the No Action Alternative. Scoping Process The process of seeking comments and public information on the proposed action, alternatives, and potential issues to be considered in the EIS is called "scoping." This report summarizes the comments received during four public scoping meetings held jointly by Reclamation and Ecology for the KKC/KDRPP EIS. In addition, both Reclamation and Ecology received comments from the interested public, including individuals, organizations, and government agencies via mail, email, telephone, and facsimile, and those comments are captured here as well. The comments received will assist in: • Identifying the significant issues relevant to these proposals, • Identifying those elements of the environment that could be affected by the proposal, • Formulating alternatives and mitigation for the proposals, and • Determining the appropriate environmental documents to be prepared. On October 30, 2013, Reclamation published a Notice of Intent to prepare an EIS in the Federal Register. Both Reclamation and Ecology issued a joint press release to Washington State media on November 6, 2013, announcing the dates and locations of scoping meetings. Meeting notices were emailed to interested individuals, Tribes, interest groups, and government agencies. Notice was also posted on Reclamation’s Integrated Plan website and associated pages describing the project, requesting comments, and providing information about the public scoping meeting. On November 4, 2013, Ecology published its Determination of Significance and public notices in area newspapers requesting comments on the scope of the EIS. Ecology also notified by email all those registered on their Yakima Basin Plan list-serve, and notice was posted on Ecology’s Office of Columbia River website. 2 On November 20, 2013, Reclamation and Ecology held two public open houses/scoping meetings at the Yakima Arboretum in Yakima, Washington—one in the afternoon and one in the evening. Twenty-three individuals attended the two meetings. At the meetings, the KKC and KDRPP proposals were described and attendees were given the opportunity to discuss the proposal with Reclamation and Ecology staff as well as comment on the scope of the NEPA/SEPA EIS, the EIS process, and resources to be evaluated in the EIS. On November 21, 2013, Reclamation and Ecology held two public open houses/scoping meetings at the U.S. Forest Service Cle Elum Ranger District Office in Cle Elum, Washington—one in the afternoon and one in the evening. Thirty-three persons attended the two meetings. The same meeting format was followed as those in Yakima. The period for comments to be included in this document was from October 30, 2013, through December 16, 2013, during which 39 comment letters were received. Reclamation and Ecology have considered the comments received to assist in the following: • Identify the significant issues relevant to the proposed action • Identify those elements of the environment that could be affected by the proposed action • Formulate alternatives to the proposed action and potential mitigation. Summary of Scoping Comments The following is a summary of comments received during the scoping period for consideration by Reclamation and Ecology during preparation of the Draft EIS: Surface Water Resources • The EIS should clarify how the KDRPP would operate. • The EIS should describe all waters of the U.S., including wetlands, that could be affected by the projects alternatives, and include maps that clearly identify all waters within the planning area, as well as the pathways of alternative routes through the planning area. The document should include data on acreages and channel lengths, habitat types, values, and functions of these waters. • What time of the year can the water be transferred from Lake Keechelus to Lake Kachess? • What will be the volume of the new stored water that will be available as opposed to the volume rerouted from Keechelus Reservoir for downstream 3 irrigation use for the purpose of bypassing the Keechelus-to-Easton reach of the Yakima River? • What will be the impact on the Kachess Reservoir refill of the 239,000 acre-feet of current active storage capacity when the inactive storage is accessed in drought years? • Has a right to the use of the inactive storage water been issued? • During a drought year, would all 200,000 acre-feet be supplied directly to the Kittitas Reclamation District? • How many seasons since 1979 has the Kachess Reservoir completely refilled? • How many seasons since 1979 has the Keechelus Reservoir completely refilled? • What are the estimated refill times for the existing Keechelus and Kachess reservoirs and with the proposed KKC and KDRPP, assuming complete drawdown during a drought year? • The EIS should address impacts to streams. • What is the transevaporation rate for Keechelus and Kachess reservoirs? • Would the proposed project supply all proratable irrigation districts with water during drought years? • Would the proposed project supply any non-proratable irrigation districts? • Can Yakima irrigation districts expand their irrigation acreage or convert to more water-intensive crops to claim access to the Kachess inactive storage during non-drought years? • The EIS should explicitly state whether any additional volumes of water rights will be granted, or whether other uses of the Kachess Reservoir Inactive Storage such as water supply to new municipalities will be allowed in non-drought years. • Would the KKC Alternative T3 option require diversion of the Yakima River? What stream alterations would be required? • What wetland impacts would occur? What mitigation is proposed? • If the pumping plant had
