Agricultural Burning
The burning of agriculture waste material generated or used by an agricultural operation on land where the primary purpose is to obtain a profit by raising, harvesting and selling crops or animals is allowed. Additionally, to qualify as an Agricultural Burner the primary living must be earned from the farm or tax returns filed as a Farmer or Grower. A CFD1 Special Burn Permit is required in order to exceed the Back Yard Burning Rules, burn out of season, or burn within the DEQ burn ban area. Special permits will only be issued on agricultural/forestry property that meets Clackamas County Zoning requirements for agricultural/forestry operations.
