Sierra Club v. EPA

Sierra Club challenged EPA's reconsideration of rules under the Clean Air Act that govern emissions to toxic pollutants from industrial boilers. The DC Circuit held that EPA did not adequately justify its change of direction on the carbon monoxide limits because it failed to explain how the revised limits would minimize the targeted pollutants to the extent the Act required. The court held, however, that EPA's startup and shutdown work practice standards were permissible because, consistent with the Act, they reasonably approximated what the best performing boilers could achieve.
