Permits Applicable to Feedlots and Manure Storage Areas


There are five different permits administered by the State that can be issued for a feedlot or manure storage area:

  1. Construction Short Form : For facilities constructing or expanding that do not pose a pollution hazard with 300 to 999 animal units. Your county feedlot officer or MPCA field staff will notify you if your feedlot is a pollution hazard.
  2. Interim : For facilities that have been determined by the RGU to be a pollution hazard or facilities with more than 300 animal units planning to apply manure on any one of the following:
    • extremely high phosphorus soils;
    • land in special protection areas and with slopes exceeding 6%; or
    • in a drinking water supply management area where the aquifer is vulnerable.
    • State Disposal System (SDS) : For facilities proposing to use new or different technologies, facilities where pollution hazards exist that were not fixed under an interim permit timeframe and feedlots with 1,000 or more animal units that are not a CAFO
    • National Pollutant Discharge Elimination System (NPDES) : For the construction and/or operation of a CAFO.
    • Individual NPDES : For CAFOs where the owners have agreed to permit conditions not covered by general permit conditions, and certain other CAFOs with past rule violations or pollution hazards, or those have been determined to require individual public noticing.

    Table 1. Summary of Registration, Permitting, and Environmental Review Process

    Table 1 lists the permit types and when they are required based on animal units. The table also outlines when an environmental assessment worksheet is required. The environmental review process will be discussed in more detail in later sections. Check with your local “planning and zoning office to see if your county or township requires “additional permits. If applicable, a permit will not be issued until the environmental review process is complete. Construction activities cannot begin until all of the appropriate permits are issued. Application forms are available online or by contacting your RGU.

    Notes

    1. Recordkeeping is required for poultry barn floors, stockpiles, and manure composting.
    2. An interim permit is not required unless a pollution hazard has been determined.
    3. A SDS Permit is required when owners of facilities are unable to fix a problem under an interim permit timeframe, or where new technology, construction, or operational methods are being used.
    4. A general NPDES Permit is not required unless the facility is a CAFO and meets criteria for general NPDES Permit.
    5. An individual NPDES Permit is not required unless the facility is a CAFO and does not meet the criteria for general NPDES permit.
    6. Registration is required only if the feedlot is located in a shoreland area.
    7. In addition to poultry barn floors, stockpiles, and manure composting, recordkeeping is required for land application of manure or wastewater for feedlots 100 animal units or greater.
    8. A manure management plan is required if your feedlot has a capacity of 100 animal units or more upon completion of NPDES, SDS, interim, or construction short form permit.
    9. An environmental assessment worksheet is required only when a governmental action, such as a local, state, or federal permit, is involved. An EAW is not required for existing feedlots unless there is modification proposed that requires governmental approval. An EAW is not required for feedlots under 1,000 animal units, or feedlots in a sensitive area of 500 animal units or less, unless through citizen petition or required at the discretion of the responsible governmental unit.
    10. Detailed recordkeeping is required for land application of manure/wastewater for facilities of 300 animal units or greater, or 100 animal units or greater if the feedlot is located in a sensitive area. See the definition of “sensitive area” in Glossary.
    11. A manure management plan is required to be completed by Jan. 1, 2005 for feedlots of 300 animal units to 1000 animal units that do not need a NPDES, SDS, interim, or construction short form permit, unless manure is applied by a certified commercial or private applicator.
    12. An interim permit is required if a pollution hazard exists, or if the manure or process wastewater of 300 or more animal units is to be applied:
      1. on land where the soil phosphorus test levels exceed the levels in Minn. Rules, Part 7020.2225, subpart 3, item C;
      2. on land in special protection areas with slopes exceeding six percent; or
      3. in a drinking water supply management area where the aquifer is designated vulnerable under Minn. Rules, Chapter 4720;
      4. If pollution hazard exists, an interim permit is required.
      5. An EAW is not required unless more than 500 animal units in sensitive area. See definition of “sensitive area” in Glossary.
      6. An SDS permit is required if the feedlot is not a CAFO.
      7. A general NPDES permit required if the facility is a CAFO and meets criteria for general NPDES permit.
      8. An individual NPDES permit required if the facility is a CAFO and does not meet the criteria for general NPDES permit.
