Which permit do I need?

Answer the following questions — in order — to determine what type of feedlot permit you may need for your facility.

Question 1

Does the facility discharge to waters of the U.S. and exceed any of the federal large CAFO thresholds?

  • Yes: Facility must obtain NDPES permit
  • No: Proceed to question 2

NOTE: There are benefits to having an NPDES permit, even if it's not required. Learn more: PDF icon NPDES and SDS permits for feedlots (wq-f3-48)

Question 2

Does the facility currently or after a proposed expansion have the capacity to house 1,000 or more animal units?

  • Yes: Facility must obtain an SDS permit
  • No: Proceed to question 3

NOTE: Coverage under an NPDES permit satisfies the need to obtain coverage under a SDS permit.

Question 3

Has a part of the facility been identified as a pollution hazard by MPCA staff or the County Feedlot Officer?

  • Yes: Facility must obtain an interim permit.
  • No: Proceed to question 4.

Question 4

Is the facility proposing construction or expansion that will result in the facility having the capacity to house 300 or more animal units, or proposing to construct a manure storage area at a facility that has capacity to house 300 or more animal units?

  • Yes: facility must obtain a CSF permit.
  • No: Proceed to question 5.

Question 5

Is the facility proposing construction or expansion that will result in the facility having the capacity to house less than 300 animal units, or proposing to construct a manure storage area at a facility that has capacity to house less than 300 animal units?
