Background:
The City of Tukwila has obtained coverage under a NPDES (National Pollution Discharge Elimination System) Phase II Municipal Stormwater Permit issued by the Washington State Department of Ecology. The NPDES is a federal requirement under the Clean Water Act that regulates stormwater and wastewater discharges to waters of the State. The permit requires that all affected municipalities create and implement a Stormwater Management Program (SWMP), which address five required program elements. These elements are:
- Public Education and Outreach
- Public Involvement and Participation
- Illicit Discharge Detection and Elimination
- Construction Site Run-Off
- Operations and Maintenance of Post Construction Stormwater Facilities
Each of these required elements has different implementation schedules but all program elements must be fully implemented within the five-year permit term.
Current NPDES Activities:
GIS Mapping - The City began a Geographic Information Systems (GIS) mapping project in 2004 that seeks to map the entire stormwater system throughout the City. As of February 2008, approximately 60% of the City's systems have been mapped.
SWMP Development - The City is working with a consultant to draft a SWMP that describes the tasks and schedule for full implementation of the permit requirements. The SWMP is a living document that will be updated annually. Surface Water Management staff are currently reviewing City procedures, determining necessary changes to the stormwater program, and drafting elements of the SWMP. As draft elements of the SWMP become available, they will be placed on this website for review and comment.
