The U.S. Court of Appeals for the District of Columbia Circuit put a hold on a case September 27 on the Environmental Protection Agency’s rule revising state and power plant emissions requirements related to its Cross-State Air Pollution Rule. The court struck down the rule in August, sending it back to the agency for a rewrite. The case now on hold was filed separately by industry groups over changes the agency made to the rule after it was finalized, including some plant emission requirements and state implementation plans in Arkansas, Louisiana, Mississippi, and Texas.
