"Maryland Attorney General Brian Frosh (D) sued the Trump administration Wednesday to try to force it to take action against out-of-state power plants for their air pollution.

Frosh contends in his lawsuit that the Clean Air Act obligates Environmental Protection Agency (EPA) head Scott Pruitt to require plants in five states to use air pollution controls.

But the EPA hasn’t formally responded to Maryland’s November 2016 petition on the matter, nor its July threat to sue the EPA for missing the deadline to respond."
