We invite your comments on the draft WSDOT Municipal Stormwater General Permit. You can view draft permit and related documents on the WSDOT Municipal Stormwater webpage.
Municipal stormwater general permits cover discharges from municipal stormwater systems. These are systems run by public entities that are separated from sanitary sewer systems. The WSDOT municipal stormwater permit regulates discharges from state highways, rest areas, park-and-ride lots, ferry terminals, and maintenance facilities within the urbanized areas of the state.
