The Governor of Wyoming, Matt Mead (R), filed a legal challenge to the U.S. Environmental Protection Agency’s decision to override states that were unable or unwilling to enforce permits for the largest sources of greenhouse gas emissions.

Mead argued EPA didn’t give Wyoming enough time to meet the new requirements before enforcing a federal plan.  When the new regulations took effect on Jan. 2, EPA officials took over issuing greenhouse gas permits to power plants, large factories and other industrial facilities.

The Wyoming attorney general’s office filed three petitions with the 10th U.S. Circuit Court of Appeals in Denver before the Feb. 11 deadline to challenge the agency rules.

The agency rules have also been challenged by Texas Attorney General Greg Abbott (R), who filed lawsuits to challenge every step that EPA has taken to limit emissions linked to climate change. The rules have also been challenged by the National Mining Association, two groups of unnamed power companies and Peabody Energy Corp., which has a presence in Wyoming’s Powder River Basin coal fields.
