The U.S. Court of Appeals for the District of Columbia Circuit granted the Environmental Protection Agency’s request September 12 to hold litigation challenging the agency’s air toxics standards for new power plants in abeyance while it completes an administrative reconsideration of the standards. The emissions limits for new sources are more stringent than for existing sources, and new plant issues are being litigated separately from other challenges to the rule. The agency issued a final rule in December setting numeric emissions limits for mercury, filterable particulate matter as a surrogate for toxic metals, and hydrogen chloride as a surrogate for acid gases. It plans to complete the reconsideration process by March.
