The Supreme Court on Friday turned down a request from Republican-led states and industry groups to block a rule from the Environmental Protection Agency that imposes more stringent standards on emissions of hazardous air pollutants from coal-fired power plants. At the same time, the justices turned down a similar request from Oklahoma and industry groups to block an EPA rule that seeks to regulate emissions of methane, a powerful greenhouse gas, from crude-oil and natural gas facilities.
Friday’s orders mean that both rules will remain in effect while challenges to them move forward in a federal appeals court in Washington, D.C.
The challengers complained that the new rule will impose billions of dollars in costs on power plants without providing any real public health benefits. Instead, the challengers suggested, the rule is part of a broader plan to (as the states, led by North Dakota contended) “force a nationwide transition away from coal for putative climate change reasons – pursuing a national policy choice this Court has expressly held the agency lacks authority to make.”
