NPDES and SDS permits

Large dairy feedlotFederal 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 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.

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.

Virtual demonstration

The MPCA will be hosting virtual demonstrations of the new online permit application service and will also be available to answer your questions about using the service.

Now that the service is available, owners need to apply for new coverage by September 1, 2022.
