Announcing for Review and Comment
Draft Aquatic Mosquito Control General Permit
Proposed Permit for Reissuance: The Washington state department of ecology (ecology) proposes to reissue the aquatic mosquito control general permit.
State and federal water quality regulations do not allow the discharge of pollutants to waters of the state without permit coverage. The chemicals allowed for use in the proposed permit are potential pollutants, and therefore require a discharge permit. When the permitted activities are similar, ecology issues general permits in place of a series of individual permits.
Purpose of the Permit: The aquatic mosquito control general permit is a national pollutant discharge elimination system (NPDES) permit and state waste discharge permit. The permit conditionally authorizes discharges of larvicides and indirect discharges of adulticides to surface waters of Washington state, to control mosquitoes.
Copies of the Draft Permit: Starting on March 6, 2019, the draft permit, fact sheet, and other supporting documents are available on the following web page:
Additionally, you may request copies of documents from Stacey Callaway via email or 360-407-7118.
Workshop and Public Hearing: The workshop will explain the proposed revisions to the permit and answer questions about the proposed revisions prior to the public hearing. The hearing will begin after the public workshop and will conclude when public testimony is complete.
During the hearing, the public may give oral testimony and written comments on the permit. Written comments will receive the same consideration as oral testimony.
