We propose modifying the following two aquatic pesticide general permits to allow the use of additional tools to control aquatic plants, algae, noxious weeds, and quarantine-listed weeds:
We invite your comments on the draft modified permits. You can find information on proposed changes and view draft documents on each permit webpage above.
We regulate aquatic pesticides released into water under the National Pollutant Discharge Elimination System (NPDES) Permit. These permits regulate 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.
