Proposed combined sewer overflow projects pose no significant environmental impacts

Environmental Impact Statement not needed; public comment period to run from April 28 through May 16

King County’s Wastewater Treatment Division (WTD) today issued an environmental review of two proposed projects to control combined sewer overflows (CSOs) in Puget Sound near West Seattle and North Beach. The reviews were conducted in accordance with the State Environmental Policy Act (SEPA). 

King County issued a SEPA Determination of Non-Significance, or DNS, for the Murray Avenue CSO project in West Seattle, which would entail building a 1-million-gallon storage tank beneath private property across from Seattle’s Lowman Beach Park. A DNS was also issued for a proposal to build a 230,000-gallon underground storage tank in the street right-of-way adjacent to the North Beach Pump Station in northwest Seattle.

The SEPA process requires WTD to fully evaluate the environmental impacts of its projects and to document and make public the findings. The DNS was issued after the agency determined that the projects do not have probable significant adverse impacts on the environment, and that an Environmental Impact Statement for the projects isn’t required under the conditions of state law.

King County is proposing these projects to protect public health and the environment by reducing the volumes of untreated combined sanitary sewage and stormwater released to Puget Sound during heavy rains.

People can find additional information about the proposed projects on the Web at

Documents for the Murray CSO project will also be available to review at the Seattle Public Library West Seattle Branch, 2306 42nd Ave. S.W., Seattle. Documents for the North Beach project can be viewed at the Seattle Public Library Ballard Branch, 5614 22nd Ave. N.W.
