National Pollutant Discharge Elimination System (NPDES) Permit

Pollutants picked up by stormwater are a significant source of water quality problems in our streams and the Puget Sound.  The National Pollutant Discharge Elimination System (NPDES) Permit is a permit created under the Federal Clean Water Act.  It is intended to help protect and restore water quality by reducing pollutants entering our waters.  Authority over the Permit program is given to Washington State Department of Ecology (DOE).   The NPDES Phase II Municipal Stormwater Permit for Western Washington initially went into effect in February 2007, and has been renewed through July 31, 2018.  The City of Mukilteo is a Permittee under this Permit.

The NPDES Phase II Municipal Stormwater Permit can be viewed at DOE’s webpage.

Annual Surface Water Management Program (SWMP) Plan

One of the NPDES Permit requirements is for the City to create an Annual Surface Water Management Program (SWMP) Plan.  The purpose of the SWMP Plan is to outline the City’s planned stormwater program activities for the upcoming year, as they relate to the NPDES Permit.  The SWMP Plan differs from the Comprehensive Surface Water Management Plan in two important ways: 1) the Comprehensive SWMP looks many years into the future; the Annual SWMP Plan covers one year at a time, and 2) the Comprehensive SWMP encompasses all activities of the Utility; the Annual SWMP Plan only covers those activities meant to meet NPDES Permit requirements.
