On March 29 and April 1, eleven separate suits were filed in the U.S. Court of Appeals for the District of Columbia Circuit over the Environmental Protection Agency (EPA) final rule on air toxic standards for industrial boilers. The rule adjusted the emission limits and gave industry more time to comply with the standards; it has been challenged for several reasons including implementation issues and weak standards. The petitioners, who are expected to be combined into a single case, are the American Chemistry Council, the American Forest and Paper Association, the American Petroleum Institute, Eastman Chemical Co., the Auto Industry Forum, the Coalition for Responsible Waste Incineration, the Council of Industrial Boiler Owners, JELD-WEN Inc., the Louisiana Environmental Action Network, the U.S. Sugar Corp., and the Utility Air Regulatory Group.
