Colorado attorney general joins lawsuit over clean air rules


DENVER | Colorado Attorney General Cynthia Coffman says she’s joining other states in a lawsuit challenging President Barack Obama’s Clean Power Plan.

Coffman said Friday that she and attorneys general in 23 other states will file a single suit saying the Environmental Protection Agency doesn’t have the authority to require states to enact pollution rules.

Coffman spokesman Roger Hudson says two other states are expected to file separate legal challenges.

The lawsuit appears to put Coffman, a Republican, at odds with Democratic Gov. John Hickenlooper. Hickenlooper said in May the Clean Air Act gives the EPA the authority to develop regulations and that Colorado would draw up a clean power plan to comply.

Hudson says Coffman disagrees with Hickenlooper. Hickenlooper’s spokeswoman didn’t immediately respond to an email seeking comment.
