Pesticide NPDES permit program

The MPCA finalized four separate National Pollutant Discharge Elimination System (NPDES) / State Disposal System (SDS) Pesticide General Permits on Nov. 16, 2011.

Entities that exceed a threshold are required to submit an application for permit coverage — known as a Notice of Intent (NOI) — and pay an application fee. Those that do not exceed the threshold are not required to submit an NOI or an application fee, but are automatically covered by the permit and must comply with basic permit requirements.

News for Dept. of Natural Resources (DNR) Aquatic Plant Management (APM) Holders!

The MPCA finds that the APM program administered by the DNR is sufficient to control the discharge of pesticides to meet the conditions of the Clean Water Act and the MPCA’s NPDES/SDS Pesticide General Permit. Therefore, APM Permit Holders do not need to submit an NOI or a permit fee, regardless of size of the activity. The MPCA and DNR finalized an Interagency Agreement so Permit Holder information can be shared between agencies. Please contact the staff listed at the bottom of this page with questions or for more details.

For more information, you can also review the letter below that was sent to potential APM permit holders.

Letter to potential APM permit holders (wq-wwprm9-26)

Mosquito and Other Flying Insect Pest Control Pesticide General Permit — NPDES/SDS General Permit MNG87A000
Forest Canopy Insect Pest Control Pesticide General Permit — NPDES/SDS General Permit MNG87B000
Aquatic Nuisance Animal Pest Control Pesticide General Permit — NPDES/SDS General Permit MNG87C000 — modified to accommodate APM permit holders (see above)
Vegetative Pests and Algae Control Pesticide General Permit — NPDES/SDS General Permit MNG87D000 — modified to accommodate APM permit holders (see above)

The MPCA collaborated with other state agencies to develop the permit and participated in several industry meetings to educate those affected by the permit on the new requirements. This permit will supply the MPCA with information on the types of pesticides used and the frequency of application in Minnesota waters, allowing the agency to make decisions about discharges, pollutants, synergistic effects, and other water-management issues.
