The National Pollutant Discharge Elimination System (NPDES) Permit (Permit) is a federal permit that regulates stormwater and wastewater discharges to waters of the State. While it is a federal permit, the regulatory authority has been passed to the Washington State Department of Ecology (Ecology). The first Western Washington Phase II Municipal Stormwater Permit was issued by Ecology in January of 2007. The current permit term is five years, beginning August 1st 2019 and ending July 31st 2024.
The Permit requires that all affected municipalities create and implement a Stormwater Management Program (SWMP) which addresses five required program elements:
Select cities, such as the City of Marysville, are required to provide additional actions applicable to Total Maximum Daily Load (TMDL) requirements.
The Draft 2020 Stormwater Management Program (SWMP) Plan is now avaialble for review. Comments can be sent to Brooke Ensor via email at firstname.lastname@example.org or by phone at 360-363-8288 through February 29th.
