On July 29, 2016, the U.S. Court of Appeals for the DC Circuit released a very long (156 pages) opinion essentially upholding every regulatory decision made by the EPA in three major Clean Air Act (CAA) rulemakings: the “Major Boilers Rule”; the “Area Boilers” rule; and the “Commercial/Industrial Solid Waste Incinerators” (CISWI) rule. The consolidated cases are United States Sugar Corporation v. EPA; American Forest & Paper Association, et al. v. EPA; and American Chemistry Council v. EPA. These new rules , according to the Court, “set emissions limits on certain combustion machinery known to release hazardous air pollutants (HAPs),” and each rule was promulgated on March 21, 2011.
