Spilled gas and leaking oil are major sources of stormwater pollution.
The National Pollutant Discharge and Elimination System (NPDES) is a federal permit governing stormwater. Under NPDES, the City of Shoreline is allowed to discharge stormwater to waters of the State (i.e. local lakes, streams and Puget Sound) if the City takes certain actions to minimize stormwater pollution.

Part of the NPDES is to have a Stormwater Management Program (SWMP). This document outlines the stormwater activities that the City intends to implement during the upcoming year including:
- Public involvement and participation
- Illicit discharge detection and elimination
- Controlling stormwater run-off from construction sites
- Operations and maintenance of stormwater facilities after construction
The Utility provides many stewardship opportunities for residents to get involved in reducing pollution and restoring stream habitat.
The Environmental Protection Agency issues the NPDES permit. Washington State Department of Ecology (DOE) administers and acts as the regulatory authority in Washington State. The full permit can be viewed at DOE’s webpage NPDES Phase II Municipal Stormwater Permit.
