Public Notice - Announcing the Draft Phase I and II Western Washington Municipal Stormwater General Permits

Proposed Permits: The Washington state department of ecology (ecology) is proposing draft Phase I and Phase II Western Washington national pollutant discharge elimination system (NPDES) municipal stormwater general permits (permits). Ecology issued the two current permits January 17, 2007. As required by RCW 90.48.260, ecology is working to reissue the Phase II Western Washington permits by July 31, 2012. RCW 90.48.260 directs:

By July 31, 2012, the department shall:

(a) Reissue without modification and for a term of one year any national pollutant discharge elimination system municipal storm water general permit first issued on January 17. 2007; and

(b) Issue an updated national pollutant discharge elimination system municipal storm water general permit for any permit first issued on January 17, 2007. An updated permit issued under this subsection shall become effective beginning August 1, 2013.

In summer 2012, ecology will reissue the Phase I permit with modifications to monitoring requirements for a term of one year, and will issue an updated Phase I permit to become effective beginning August 1, 2013.

Purpose of the Permits: These permits are required in urban areas that collect stormwater runoff in municipal separate storm sewers and discharge it to surface waters. A municipal separate storm sewer system (MS4) is a conveyance or system of conveyances including roads with drainage systems, municipal streets, catch basins, curbs, gutters, ditches, man-made channels and/or storm drains which is:

1. Owned or operated by a city, town, county, district, association, or other public body created pursuant to state law having jurisdiction over disposal of sewage, industrial wastes, stormwater, or other wastes, including special districts under state law such as sewer districts, flood control districts or drainage districts, or similar entity;

2. Designed or used for collecting or conveying stormwater;

3. Not a combined sewer system; and

4. Not part of a publicly owned treatment works (POTW) (see 40 C.F.R. 122.2).

The permits are required under the federal Clean Water Act.
