On March 25, several trucking groups filed charges against the Environmental Protection Agency (EPA) in the U.S. Court of Appeals for the District of Columbia Circuit over a decision involving light duty vehicles. The lawsuit contests the agency’s denial of petition to reconsider emission standards for light duty vehicles for model year 2012 through model year 2016. The groups include the California Construction Trucking Association Inc., the Delta Construction Co. Inc., the Southern California Contractors Association, and the Pacific Legal Foundation.
