Do I need a permit for the manure generated by my animals?
The Oregon Department of Agriculture issues a Confined Animal Feeding Operation (CAFO) permit to livestock owners so manure does not pollute ground and surface water.
There are three main factors that determine if your farm needs a CAFO permit:
- How many animals you have.
- How long the animals are confined for in a prepared area (e.g. in a barn, lot, pen).
- How the manure and wastewater generated by the farm is stored (e.g. do you collect your manure in a tank or do you stack it in a pile).
Reference table 1 in the National Pollutant Discharge Elimination System (NPDES) General Permit or in the Water Pollution Control Facilities (WPCF) General Permit to determine whether the permit is required. For more information, see the CAFO geographic boundaries resource to contact the livestock water quality specialist in your area.
How do I apply for a permit?
For operators not currently permitted, complete Application to Register (ATR) to the Oregon CAFO permit and review the animal waste management plan minimum requirements when completing section IV of the ATR.
What are the fees related to CAFO permits?
There is an application fee of $100 for a small CAFO, $150 for a medium CAFO, and $300 for a large CAFO when applying for a permit. There also is an annual permit fee. Depending on the size of your operation, the annual permit fee will be:
- $125 for a small CAFO
- $250 for a medium CAFO
- $400 for a Tier 1 large CAFO
- $900 for a Tier 2 large CAFO
For more information, see the CAFO fee table.
What if I need a CAFO permit but decide not to get one?
Failing to apply for a CAFO permit, if required, is a violation of state law and you may be assessed a financial penalty.
