D.C. Circuit Upholds NSPS for Coal-Fired Plants, Ratifies White House, Congressional Input Into Rulemaking
In June 1979, the Environmental Protection Agency (EPA) promulgated new source performance standards (NSPS) to control particulate and sulfur dioxide emissions from coal-fired power plants. In Sierra Club v. Costle,1 decided in April 1981, the District of Columbia Circuit Court of Appeals upheld the standards against an array of substantive and procedural challenges by both industry and environmental groups.
