Announcing a Draft Industrial Stormwater General Permit for Review and Comment
The Washington state department of ecology (ecology) proposes to reissue the industrial stormwater national pollutant discharge elimination system and state waste discharge general permit. The permit was last issued December 3, 2014, and is scheduled to expire on December 31, 2019. The new draft permit and fact sheet, which explains the technical bases for the permit, are available for review and public comment from May 1, 2019, until 11:59 p.m., on June 29, 2019. Ecology will host informational workshops and public hearings on the draft permit.
PURPOSE OF THE PERMIT: The permit addresses various legal requirements and responsibilities, and regulates the discharge of pollutants to protect water quality in Washington state. State and federal water quality statutes and regulations do not allow the discharge of pollutants to waters of the state without permit coverage. Stormwater may become contaminated by industrial activities as a result of contact with materials stored outside, spills and leaks from equipment or materials used onsite, contact with materials during loading, unloading or transfer from one location to another, and from airborne contaminants and therefore require a discharge permit. When the permitted activities conducted by a specific class of industries are similar, ecology issues a general permit to cover all of them rather than issuing a series of individual permits.

ISSUING THE PERMIT: The final decision on permit issuance will be made after ecology receives and considers all public comments.

Ecology expects to issue the general permit in November 2019. The permit will become effective January 1, 2020.
