Updated combined permit coming soon

Ecology is updating and combining this permit with two others (the Fisheries Resource Management and the Aquatic Invasive Species Management) into one new Aquatic & Invasive Species Control general permit.

The draft permit documents will be available for review and comment between Dec. 21, 2022 and Feb. 6, 2023.

Ecology will review any comments and revise the draft documents, then decide about issuing the new permit in March 2023.

For more details, please visit our new Aquatic & Invasive Species Control general permit webpage. Note: Please bookmark the webpage, as this invasive moth control permit webpage will eventually go away.

This permit is designed to protect water quality during efforts by the Washington State Department of Agriculture to eradicate Asian and European gypsy moths. This permit is a combined National Pollutant Discharge Elimination System (NPDES) and State Waste Discharge Individual Permit.
