WASHINGTON (AP) — A divided federal appeals court Tuesday overturned a regulation clamping down on power plant pollution that contributes to unhealthy air in neighboring states.
In a 2-1 decision, a panel of the U.S. Court of Appeals for the District of Columbia Circuit said the Environmental Protection Agency's cross-state air pollution rule exceeded the agency's statutory authority. The court faulted the EPA for imposing "massive emissions reduction requirements" on upwind states without regard to limits imposed by law.
In adopting the regulation a year ago, the EPA sought to reduce downwind pollution from power plants in more than two-dozen states. The rule was scheduled to go into effect in January, but several large power companies and some states sued to stop it. The appeals court agreed last December to suspend the rule pending its review.
"Our decision today should not be interpreted as a comment on the wisdom or policy merits of" the EPA rule, wrote Judge Brett Kavanaugh, in a decision joined by Judge Thomas Griffith — both appointees of Republican President George W. Bush. "It is not our job to set environmental policy. Our limited but important role is to independently ensure that the agency stays within the boundaries Congress has set. EPA did not do so here."
In a dissent, Judge Judith Rogers, an appointee of Democratic President Bill Clinton, said that the court had disregarded "limits Congress placed on its jurisdiction, the plain text of the Clean Air Act, and this court's settled precedent interpreting the same statutory provisions at issue today. Any one of these obstacles should have given the court pause; none did."
Sulfur dioxide and nitrogen oxide pollution from power plants can be carried long distances and the pollutants react with other substances to form smog and soot, which have been linked to illnesses. The cross-border pollution has prevented many cities from complying with health-based standards set by law.
EPA spokeswoman Alisha Johnson said the agency is reviewing the decision, and will determine what steps to take after the review is complete.
"EPA remains committed to working with states and the power sector to address pollution transport issues as required by the Clean Air Act," she said.
Tuesday's ruling follows a decision June 26 by a different panel of judges in the appeals court upholding the first-ever regulations aimed at reducing the gases blamed for global warming.
