A federal appeals court on April 5 ruled against two Clean Air Act rules set by the U.S. Environmental Protection Agency under the Trump Administration— one that delayed a requirement for states to meet landfill pollution controls and another that exempted most stationary air pollution sources from protective standards.
The Biden Administration in March asked the U.S. Court of Appeals for the District of Columbia to vacate the rule that delayed implementation of 2016 limits to methane released from solid waste landfills by installing controls to capture emissions.
