Industry groups, Republican-led states and environmental organizations are squaring off in a widening legal battle over the EPA crackdown on cancer-causing chemical plant emissions.
Against the backdrop of this week’s statutory deadline for bringing legal challenges, at least seven lawsuits are pending before the U.S. Court of Appeals for the District of Columbia Circuit.
Among the latest entrants: The state of Texas; the Vinyl Institute; the American Chemistry Council; Huntsman Petrochemical; and a coalition of environmental groups led by Concerned Citizens of St. John, based in a Louisiana parish that’s home to a Denka Performance Elastomer plant that is already enmeshed in a related fight.
