Phase I Municipal Stormwater Permit Modification - 2010

Ecology modified the Phase I Municipal Stormwater permit on September 1, 2010. The purpose of the permit modification was to incorporate Ecology's equivalency determination of Clark County's Flow Control Mitigation Program. Ecology also incorporated minor updates to King County and the City of Seattle's equivalency documents.

Ecology held a public review and comment period from April 21, 2010 through June 7, 2010. In addition, Ecology held a public hearing in Vancouver, WA on May 27, 2010. No formal comments were received at this hearing; however, Ecology received the written comments listed below. After considering comments, Ecology formally responded in the Response to Comments below. Ecology issued the final permit modification on September 1, 2010.

The effective date of the newly modified permit is October 1, 2010.

Ecology received one appeal of the modified Phase I Municipal Stormwater Permit. The modified permit became effective on September 1, 2010, and remains in effect. Please continue to check this page for updates related to the appeal.
