Water Cleanup Plans, or Total Maximum Daily Load projects, are required under the federal Clean Water Act for waters of the state that are not sufficiently clean to support their best uses for recreation, fishing, shellfishing, and aquatic life. Sinclair and Dyes Inlets need a cleanup plan for fecal coliform bacteria, in order to open more of these marine waters to shellfish harvest. To develop a plan, Ecology is coordinating a series of meetings with local government (Kitsap County and the cities of Bremerton, Bainbridge Island, and Port Orchard), the Puget Sound Naval Shipyard, Suquamish Tribe, and other local organizations with an interest and responsibility to get the waters clean. In the implementation plan, the results of the water quality monitoring and modeling by the Navy will be used to identify the most important sources of bacteria around the two inlets. The plan will identify activities by individual organizations and government programs needed to reduce bacteria loading to the inlets.
Because stormwater is an important contributor of bacteria to these waters, the plan will consider what elements of Ecology’s new Phase II Municipal Stormwater Permit will help to reduce contributions of bacteria-laden stormwater to the inlets. We also know that during the late-summer low-flow period, streams that discharge to the inlets are important contributors of bacteria. Kitsap County Health District’s Pollution Identification and Correction projects are already being focused on several of the streams in this TMDL. Some locations around the inlets are already starting to show improvement.
