Twelve state attorneys general filed a suit against the Environmental Protection Agency in the U.S. District Court for the Western District of Oklahoma on July 16, urging the agency to release information on its sue and settle strategy. The agency recently failed to comply with a Freedom of Information Act request; the states had requested communications documents related to a Clean Air Act regional haze program settlement. The states represented were AL, AZ, GA, KS, MI, ND, NE, OK, SC, TX, UT, and WY.
