The Biden administration is expanding restrictions on carbon emissions that could impact half the liquefied natural gas (LNG) export capacity in the U.S.
The Environmental Protection Agency (EPA) is expanding a rule under the U.S. Clean Air Act called the National Emissions Standards for Hazardous Pollutants (NESHAP), which places restrictions on the emission of formaldehyde and benzene from stationary combustion turbines. Starting in August, the rule will now apply to two types of gas-fired turbines that were previously left out of the regulation, the EPA announced in February.
The Supreme Court heard arguments in West Virginia v. EPA on Monday, a blockbuster case that could have major ramifications in future separation of powers cases.
The case, which stems from an Obama administration climate rule, has wide-ranging implications for how the federal agencies may issue future regulations and rules, according to the parties that brought the case before the high court. States, environmental groups, large power utility companies, civil liberties organizations and pro-coal industry groups have inserted themselves in the case over the last several years, signaling the importance of the questions it has raised.
