NPDES Phase II Municipal Stormwater Permit Program

As part of the City’s 2013-2018 stormwater permit issued by the Department of Ecology (DOE), the City is required to update our stormwater regulations to be consistent with and equivalent to the DOE surface water manual.  For this purpose, the City is soliciting input and comments on amendments to the City’s Infrastructure Design and Construction Standards Manual and  Tukwila Development code to include Low Impact Development. Also, to maintain consistency with the DOE surface water manual the City will be adopting the 2016 King County Surface Water Design Manual and the 2016 King County Stormwater Pollution Prevention Manual.

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. The permit requires that all affected municipalities create and implement a Stormwater Management Program (SWMP), which address five required program elements. These elements are:

  1. Public Education and Outreach
  2. Public Involvement and Participation
  3. Illicit Discharge Detection and Elimination
  4. Construction Site Run-Off
  5. 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.

 

Projects

East Marginal Way South. Storm Outfalls Project                                                                           

East Marginal Way S. Storm Outfalls Project design is 90% complete. This project is located in the Boeing /East Marginal Way area and will provide flow control and stormwater quality treatment utilizing Low Impact Development techniques for drainage connections to the Duwamish River. This project is made possible through a $120,000 grant awarded to the city by the Washington State Department of Ecology.

 

Geographic Information System (GIS)

The City’s GIS Database includes mapping of receiving water body outfalls, drainage pipes 8” and larger including pipe invert, materials and condition. GIS mapping will continue to be updated as needed. The mapping was made possible through the City’s Surface Water (Storm Drainage) Utility fund and a Washington State Department of Ecology grant.

 

Resources

Annual Report

The permit requires the City to submit annual reports to the Department of Ecology no later than March 31st for the preceding calendar year.
