Court Rejects E.P.A. Limits on Emissions Rules

A federal appeals court on Tuesday threw out an Environmental Protection Agency rule limiting the ability of states to require monitoring of industrial emissions.

The 2-to-1 ruling by the United States Court of Appeals for the District of Columbia Circuit is the most recent in a series of judicial setbacks to the Bush administration’s efforts to reshape federal policies under the Clean Air Act.

Under 1990 amendments to the original Clean Air Act, states were allowed to issue permits limiting pollution emissions from industrial facilities, like refineries or utilities. To ensure compliance, Congress required states to set more stringent monitoring requirements if they deemed federal requirements inadequate.
