Welcome to the National Pollutant Discharge Elimination System (NPDES) webpage for Whatcom County
Whatcom County has set up the NPDES Phase II website to help inform residents of Whatcom County on requirements of our current NPDES Phase II Municipal Stormwater Permit, provide resources and education on our program areas, and to achieve compliance with Permit requirements.
The NPDES Phase II Municipal Stormwater Permit was issued by the Washington State Department of Ecology originally in February of 2007. (This is also referred to as the Western Washington Phase II Municipal Stormwater Permit.) It sets forth requirements of municipalities to address stormwater runoff in areas determined to have population densities reaching urban standards. Click here to learn more about if NPDES Phase II requirements pertain to where you live.
