In accordance with Federal Requirements in the Clean Water Act, the NPDES section is in the process of developing a general permit for the application of pesticides to Waters of the United States (U.S.). The Iowa DNR has until
April 9, 2011 to issue a final general NPDES permit for pesticide applications. Coverage under this permit will likely be required for pesticide applications that result in residue discharges to Waters of the U.S. Applicable pesticide applications include those for control of mosquitoes and other aquatic nuisance insects, control of weeds, algae, bacteria, fish parasites, control of aquatic nuisance animals, and forest canopy pest control.
DNR staff presented the Notice of Intended Action (NOIA) concerning the draft pesticides General Permit (PGP) to the
Environmental Protection Commission (EPC) at their meeting on August 17, 2010. The NOIA rulemaking action was approved and it will be published
in the Iowa Administrative Bulletin. Please see the links below for more information concerning the draft permit, the waterbodies
referenced in the draft permit, the rulemaking timeline, the upcoming public hearings, and information on previous stakeholder meetings.
