Clean Air Act: The Status of EPA’s Methane Regulation Rollbacks and Associated Litigation

Fri Dec 18th, On Litigation, Rulemaking and Legislative Practice, by

Methane is the main ingredient of natural gas and a potent greenhouse gas (“GHG”) with a short half-life. When methane leaks into the air before its use—from a leaky valve at a drilling site, for example—it absorbs the sun’s heat and warms the Earth’s atmosphere.

U.S. Supreme Court Stays EPA’s Clean Power Plan

Thu Feb 11th, On Environmental Law, by

U.S. Supreme Court on Tuesday stayed the implementation of EPA’s Clean Power Plan, overruling the D.C. Circuit’s January 21 decision. As a result, EPA is now prevented from implementing the rule until the D.C. Circuit determines the validity of the rule, and the Supreme Court reviews that ruling. The question now before the D.C. Circuit (and to be before the Supreme Court upon review) is whether EPA has the authority […]
