High Court Rejects Bid to Stay Mercury Air Toxics Rule

On Thursday, the U.S. Supreme Court rejected a request to stay the EPA’s Mercury and Air Toxics Standards rule. The rule, which requires coal-fired power plants to greatly reduce mercury and other toxic emissions, was struck down in June because the EPA had not considered the $1 billion cost of imposing the rule. The D.C. Circuit left the original rule in place, however, while the EPA worked to bring the rule into compliance by issuing a supplemental consideration of cost. The EPA plans to finalize its supplemental consideration in April in response to the Supreme Court’s June decision.
