Announcing the Issuance of the Modified Phase I

Municipal Stormwater General Permit

Permit Issuance: The Washington state department of ecology (ecology) will issue the final modified Phase I municipal stormwater general permit (permit) on September 1, 2010. The permit was issued on January 17, 2007, then first modified June 17, 2009, and modified for the second time September 1, 2010. The permit modification incorporates ecology's equivalency determination of Clark County's flow control program by updating Appendix 10 of the Phase I permit. The modification also incorporates minor updates to King County and the City of Seattle equivalency documents.

Purpose of the Permit: Federal and state water quality laws require a permit for the discharge of stormwater (see Federal Water Pollution Control Act, Title 22 United States Code, Section 1251 et seq., state Water Pollution Control Act, chapter 90.48 RCW and Washington waste discharge general permit regulation, WAC 173-226-130). The permit addresses these legal requirements and controls the discharge of pollutants to protect surface water and ground water quality in Washington state. The permit requires municipalities and secondary permittees covered by the permit to develop and implement a stormwater management program to control stormwater runoff into and from their storm sewer system.

Public Notice Process and Comments: Ecology accepted public comments on the draft permit and fact sheet from April 21, 2010, until June 7, 2010. Ecology held a hearing and workshop in Vancouver, Washington, on May 27, 2010. Ecology received comments from five commenters during the public comment period and responded to comments in a response to comments appended to the fact sheet. The response to comments, permit, and the fact sheet are available for review at ecology's web site at
