Supreme Court blocks EPA's interstate air pollution regulation
WASHINGTON — The Supreme Court on Thursday blocked a Biden administration environmental regulation aimed at curbing harmful air pollution that crosses from one state to another and contributes to the formation of smog.
In doing so, the court on a 5-4 vote granted requests from three Republican-led states — Indiana, Ohio and West Virginia — and various affected industries, including natural gas pipeline operators.
Conservative Justice Amy Coney Barrett sided with the court's three liberals in disagreeing with the outcome.
The Environmental Protection Agency regulation applied to 23 states, although lower court rulings meant it was already blocked in 12 of them.
The Supreme Court, which has a 6-3 conservative majority, is skeptical of broad exertions of federal power on regulatory issues, including the environment.
As a result, it is receptive to legal challenges mounted by Republican attorneys general and industry groups that have long griped about the EPA’s aggressive use of its regulatory powers.
The EPA’s “good neighbor plan” was announced last year in a bid to curb nitrogen oxide pollution from industrial facilities. If implemented in full, it would apply to 23 “upwind” states whose emissions can contribute to pollution in “downwind” states.
The EPA said the plan, based on a requirement in the Clean Air Act, would help prevent premature deaths, reduce emergency room visits and cut asthma symptoms by limiting the amount of smog.
Typically, states get a chance to draw up their own pollution control plans. Each state is required under the Clean Air Act to be a “good neighbor,” meaning that it should address pollution that can contribute to other states not meeting their own obligations.
The EPA can step in to adopt its own plan, which is what happened last year. The three states complained about the federal government’s approach, saying in part that they didn’t have enough time to come up with their own plans.
In two other important recent environmental cases at the Supreme Court, the EPA lost both times.
In 2022, the court limited the ability of the agency to use the Clean Air Act to combat emissions that contribute to climate change. Last year, the court weakened the landmark Clean Water Act by limiting the EPA’s regulatory oversight over wetlands.
