Announcing the Draft Aquatic and Invasive Species Control General Permitand Fact Sheet for Review and Comment
The Washington state department of ecology (ecology) proposes to reissue the draft Aquatic and Invasive Species Control National Pollutant Discharge Elimination System (NPDES) and state waste discharge general permit (permit). The new permit will replace the three permits listed below, which were previously issued to Washington state agencies and have now expired. The revised draft permit and fact sheet, which explains the legal and technical basis for the permit, are available with any associated documents for review and public comment from Wednesday, December 21, 2022, through Monday, February 6, 2023, at 11:59 p.m. Ecology will host informational workshops and public hearings on the draft permit.
Aquatic invasive species (Washington department of fish and wildlife (WDFW) - expired September 15, 2021).
Fisheries resource management (WDFW - expired September 30, 2020).
Invasive moth control (Washington state department of agriculture - expired July 23, 2009).
Purpose of the Permit: The permit provides statewide NPDES coverage for the use of specific chemicals to control invasive and introduced species of fish, animals, and insects. Under federal and state water quality laws (Federal Clean Water Act and State Water Pollution Control Act), state agencies that apply pesticides either directly or indirectly to waters of the state must obtain permit authorization for their discharge.

Agencies may obtain coverage under the permit by submitting a complete permit application to ecology and satisfying all applicable public notice and State Environmental Policy Act (SEPA) requirements (WAC 173-226-200).
