As a result of regulations in the Federal Clean Water Act (CWA), municipalities are required to comply with a National Pollutant Discharge Elimination System (NPDES) permit. This federal permit regulates wastewater and stormwater that is discharged into U.S. waters and waters of the state, including rivers, lakes, streams, and all underground waters and aquifers.
The Washington State Department of Ecology (Ecology) is the regulatory authority for the NPDES permit. Ecology issued the most-recent NPDES Phase II Municipal Stormwater Permit for Western Washington in August 2013, with a revised permit effective January 16, 2015. This permit will remain in effect until 2018.
Puyallup's Stormwater Management Program Plan (SWMPP)
One of the requirements of the NPDES permit is the development and implementation of a Stormwater Management Program Plan (SWMPP). The SWMPP, as described in the NPDES Permit, is a planning tool used to describe a municipality's current implementation of the permit, as well as plans for implementing the program in the coming calendar year.
