The proposed hatchery would be constructed at an existing Confederated Tribes of the Umatilla Indian Reservation (CTUIR) fish facility on the South Fork Walla Walla River near Milton-Freewater in Umatilla County, Oregon. The CTUIR would own and operate the hatchery to augment spring Chinook fish populations available for harvest and aid in establishing a naturally spawning spring Chinook population in the Walla Walla River basin. BPA is considering two action alternatives and a no action alternative. Alternative 1 includes construction of a hatchery for production of up to 500,000 Walla Walla spring Chinook smolts, modification of an existing adult fish trapping facility to capture broodstock, and release of juvenile and adult spring Chinook into Walla Walla River tributaries in both Oregon and Washington. Alternative 2 would be similar to Alternative 1, but would also include relocation of the production of Umatilla spring Chinook from the existing Umatilla Hatchery near Irrigon, Oregon, to the proposed Walla Walla Hatchery. The proposed Walla Walla hatchery was identified in the Northwest Power and Conservation Council’s Fish and Wildlife Program—a regional program designed to protect and rebuild fish and wildlife populations affected by hydropower development in the Columbia River Basin. The EIS analyzes impacts to surface and groundwater, fish, vegetation, socioeconomics, environmental justice, cultural resources, wetlands, floodplains, wildlife, air quality, climate change, noise, visual quality, and recreation. BPA requested comments to help determine the scope of the EIS in May 2013 and June 2014. Public review of and comment on this draft EIS will continue through November 24, 2014.
