Republican appointees to the Supreme Court criticized the EPA's rule on cross-state air pollution during oral arguments Wednesday, as the justices contemplate whether to block the rule as lower legal challenges play out.

Several of the conservative justices, who hold a 6-3 majority, questioned whether the agency should have considered how a plan that spans 23 states could change if litigation meant certain states would not be included.

The Environmental Protection Agency announced the plan last March as a national strategy to reduce air pollution that crosses state borders under the "good neighbor" provision of the Clean Air Act. Before that, the agency had rejected state-provided plans from each of the 23 in the program.

But many of the states covered by the EPA's national plan have challenged those rejections, and mean the agency's national plan currently covers only 11 of the original 23 states.

Justice Neil M. Gorsuch pointed out the agency had not explained, or given the public the chance to comment on, the effect of so few states participating in the plan. "Nobody got an opportunity to comment on that," Gorsuch said.

Justice Brett M. Kavanaugh pointed out that while the EPA's original plan said it would not change if states dropped out, it provided a "goose egg" for an explanation.

"They don't have an explanation here," Kavanaugh said.

The Supreme Court agreed to decide the issue after a series of emergency appeals last year from industry groups and three GOP-led states—Ohio, Indiana and West Virginia. They granted a rare oral argument on whether to pause the plan while the U.S. Court of Appeals for the District of Columbia Circuit considers the challenges.

The court's three Democratic appointees spent much of Wednesday's arguments questioning whether the Supreme Court should act on a rule challenge when no lower court has made a final ruling yet.

Justice Ketanji Brown Jackson said she could not see a difference between the arguments made by the states and industries opposing the rule and those made by any other challenge to a federal rule.

"I'm trying to understand what the emergency is that warrants Supreme Court intervention at this point," Jackson said.

The case comes to the court as the conservative majority has ruled against major administrative actions, particularly by the EPA, and the Republican-controlled House of Representatives has contemplated changing the agency's authority to pass standards under the Clean Air Act.

The rule requires 23 states to reduce emissions in and other industries to help reduce smog and other air pollution in neighboring states. The plan covers much of the country, including California and several Western states and a large swath of the country from Texas to New York.

Mathura J. Sridharan, the Ohio solicitor general arguing for the three GOP-led states, told the justices that the EPA's plan doesn't consider how it would change because of states dropping out of the program.

"They failed to consider the most important aspect of the interdependence they introduced," Sridharan said.
