WASHINGTON (AP) — The Supreme Court left in place Friday two Biden administration environmental regulations aimed at reducing emissions of planet-warming methane and toxic mercury from coal-fired power plants.
The justices did not detail their reasoning in the orders, which came after a flurry of emergency applications to block the rules from industry groups and Republican-leaning states. There were no noted dissents.
The high court is still considering challenges to a third rule aimed at curbing planet-warming pollution from coal-fired power plants.
The industry had argued the Environmental Protection Agency overstepped its authority and set unattainable standards. The EPA said the regulations are squarely within its legal responsibilities.
