Boating Pumpout

Clean Vessel Act

The Clean Vessel Act of 1992 established grant funding for the construction, renovation, operation and maintenance of sewage disposal systems serving recreational boaters. Washington State Parks administers our state’s Clean Vessel Act (CVA) Grant Program.

We receive CVA funding through a nationally competitive grant process, administered by the U.S. Fish and Wildlife Service. Grant funding comes from the Sport Fish Restoration and Boating Trust Fund, which is supported by excise taxes on sport fishing equipment, recreational boats and boat fuel.

No monies from state vessel registration fees, Discover Passes, fishing or crabbing licenses are used to support the Washington CVA Grant Program.

We partner with Washington Sea Grant to provide an outreach and education initiative called Pumpout Washington. This provides recreational boaters and marina operators with education about the environmental effects of improper boat sewage disposal and where to find pumpouts, dump stations and mobile pumpout services.

Keeping the waters clean

Since 2001, we have received over $21 million dollars in CVA federal grants. That has funded more than 150 projects (e.g. stationary pumpout facilities, dump stations, floating restrooms) and mobile pumpout services across the state.

The program continues to support ongoing operations and maintenance of more than 140 stationary pumpouts and dump stations, and free mobile pumpout services at 10 coastal marinas.

We are proud to support Washington boaters, who have prevented millions of gallons of sewage from contaminating Washington’s waters by using CVA pump-out facilities. A clean marine environment is very important for everyone to enjoy the beautiful bodies of water throughout Washington. Boaters are leaders in keeping Washington’s waterways clean.

puget sound is now a no-discharge zone for vessel sewage

The Washington State Department of Ecology established a Vessel Sewage No Discharge Zone (NDZ) for Puget Sound and certain adjoining waters. The NDZ was adopted April 9, 2018, after a five year public process and approval from the Environmental Protection Agency (EPA). The rule is effective May 10, 2018.
