Federal National Pollutant Discharge Elimination System (NPDES) and State Disposal System (SDS) permits are issued to the larger feedlots in Minnesota for construction and operation.
Applying for a permit
The MPCA recently finalized new State Disposal System (SDS) and National Pollutant Discharge Elimination System (NPDES) feedlot general permits. The new state SDS general permit will become effective on June 1, 2025, and the new federal NPDES general permit on Feb. 1, 2026.
Applications for the new SDS general permit are now being accepted. Those with current SDS permit coverage should reapply by May 31, 2025, to avoid a lapse in permit coverage.
- effective June 1, 2025
Applications for the new NPDES general permit will begin in fall 2025.
- effective Feb. 1, 2026
Until the fall 2025, applications can continue to be submitted for the current NPDES general permit.
- ends Jan. 31, 2026
The MPCA no longer accepts paper or email applications for NPDES or SDS permits. This includes applications for issuance, reissuance, and all types of modifications. All NPDES and SDS permit applicants must use the online feedlot permit application service. You can also make changes to your facility name, ownership information, and contact person through MPCA Online Services.
Even if you plan to have a consultant prepare your permit application you will need to use the online service to set up an account in order to sign the application.
