WASHINGTON, Sept 27 (Reuters) – The centerpiece of President Barack Obama’s climate change strategy, federal rules curbing greenhouse gas emissions mainly from coal-fired power plants, faces a key test on Tuesday when opponents try to convince a U.S. appeals court to throw out the regulations.
Twenty-seven states led by coal-producer West Virginia and industry groups are challenging the Environmental Protection Agency’s Clean Power Plan rules before 10 judges of the U.S. Court of Appeals for the District of Columbia Circuit.
They argue that the EPA overstepped its regulatory authority under the federal Clean Air Act when the agency issued the rules, which the U.S. Supreme Court has put on hold while the case is litigated.
During Tuesday’s arguments, these opponents will face off in court against the EPA, 18 states, corporations including Apple Inc and Alphabet Inc’s Google, and a number of cities that support the regulations.
