General permit documents

The draft Aquatic Mosquito Control General Permit and supporting documents are available for review on Ecology's Aquatic Mosquito Control General Permit webpage.

We regulate aquatic pesticides released into water under the National Pollutant Discharge Elimination System (NPDES) Permit. This permit regulates when, where, how, and the amount and type of products that can be applied. The permits provide details on the monitoring, reporting, and public notification requirements for using pesticides to manage aquatic organisms.
