In accordance with Federal Requirements in the Clean Water Act, the NPDES section developed a general permit for the application of pesticides to Waters of the United States (WOUS). Coverage under this permit is required for pesticide applications that result in residue discharges to WOUS. Applicable pesticide applications include those for control of mosquitoes and other aquatic nuisance insects, control of weeds, algae, bacteria, fungi and fish parasites, control of aquatic nuisance animals, and forest canopy pest control.
Please note that while the Pesticides General Permit (PGP, General Permit #7, or GP7) provides coverage under the federal Clean Water Act, there are also separate state-based requirements for applying pesticides to public waters. These state requirements must also be followed, and the rules can be found in the Iowa Administrative Code at 571 IAC Chapter 54.
For more information on EPA's General NPDES permit for pesticides, please see EPA's NPDES Pesticides Applications page.
The Iowa DNR is currently drafting a renewal of the Pesticides General Permit. A Stakeholder Meeting was held on Tuesday, May 21, 2019, to seek input on the draft GP7 from individuals, stakeholder groups, and other interested citizens.

This new draft includes one notable change from the draft presented to stakeholders on May 21, 2019.
