Oklahoma cannot define poultry litter as “solid waste” in its pollution lawsuit against Arkansas poultry companies, according to a Dec. 15 ruling by a federal judge.

U.S. District Judge Greg Frizzell dismissed Oklahoma’s claim that the litter falls under the federal Resource Conservation and Recovery Act of 1976’s solid waste regulations.


Oklahoma’s attorney general, Drew Edmondson, told the Associated Press he would appeal the ruling. His state is seeking compensation for alleged pollution of the Illinois River watershed with poultry manure.
