Department of Ecology Issues Modified Municipal Stormwater Permits; Comment Period Open

Published Aug 28, 2014

The Department of Ecology has issued draft modifications to the Phase I and Western Washington Phase II Municipal Stormwater Permits.  The proposed modifications are in response to a March 2014 ruling by the Pollution Control Hearings Board (PCHB). Ecology has also modified the Stormwater Management Manual for Western Washington (SWMMWW) based on the PCHB ruling.

Ecology is accepting written and oral comments on the permits until October 6, 2014, and will have a series of workshops and public hearings in Edmonds and Vancouver, Washington. Ecology prefers comments to be submitted by e-mail to: A workshop and webinar, with no public hearing and requiring advance registration, will be held in Lacey, Washington. A hearing will immediately follow the Edmonds and Vancouver workshops. At each workshop Ecology will explain the permit and manual modifications, and answer questions. For a full schedule of hearings and workshops, visit the Ecology webpage listed below.

Ecology will issue the final modifications after it considers all public comments and makes final changes to the draft Permits and modified Manual. Ecology will publish a response to comments submitted during the public comment period as part of the Fact Sheet accompanying the final modifications. Contact James Tupper for more information at
