CHARLESTON, W.Va. — West Virginia is speaking out against the U.S. Environmental Protection Agency's new rule on cross-state air pollution.

Attorney General Patrick Morrisey filed a brief with the U.S. Supreme Court this week. West Virginia is joined in the brief by several other states.

WSAZ-TV reports ( that the brief claims that the EPA exceeded its authority under the federal Clean Air Act.

It also argues the law requires the EPA to give states an opportunity to decide how to meet new air pollution standards.

West Virginia and 15 other states have already sued over the new regulations. A U.S. Court of Appeals struck down the regulation saying the EPA exceeded its statutory authority.

The Supreme Court has since agreed to review the case. Oral arguments are expected next month.
