The state Department of Ecology received requests from the Washington Department of Fish and Wildlife, the Columbia River Inter-Tribal Fish Commission, and a coalition of non-governmental organizations to further adjust its total dissolved gas criteria for dams that spill to aid fish passage.
Providing a short-term adjustment could allow dams to increase spill during portions of the day to help juvenile fish migrating to the ocean. Also, modifying the criteria is consistent with current recommendations from the Governor’s Southern Resident Killer Whale task force, may help harmonize water quality standards with Oregon, and could simplify the U.S. Army Corps of Engineers' implementation of the spill program at its federal dams on the lower Snake and Columbia rivers.
Ecology has extended the deadline for comments from the public through Dec. 14, 2018.
Ecology is seeking comments on an Environmental Impact Statement (EIS) Scoping Notice for a short-term modification to its total dissolved gas criteria (WAC 173-201A) for areas on the Snake and Columbia rivers. This is the first step to evaluating potential environmental impacts of adjusting the total dissolved gas criteria, and Ecology will consider comments on the scope to help Ecology develop a draft EIS.
How to comment:
Ecology invites tribes, agencies, organizations, and members of the public to comment on the scope of its draft Environmental Impact Statement (EIS) until Dec. 14, 2018. Comments on alternatives, mitigation, impacts, and other items Ecology should consider in the EIS are welcome.
EIS Scoping Period: November 16 - December 14, 2018
