"The Hogan administration notified the federal Environmental Protection Agency on Thursday that it plans to file a lawsuit alleging the agency has failed to act against states whose smokestack emissions pollute Maryland’s air.

In a letter to EPA Administrator Scott Pruitt, Maryland Environment Secretary Ben Grumbles charged that the Trump administration has failed to enforce mandatory provisions of the Clean Air Act despite evidence that five upwind states are illegally emitting nitrogen oxide that contributes to Maryland’s pollution problems.

The warning signals a new aggressiveness in Gov. Larry Hogan’s approach toward President Donald J. Trump, a fellow Republican whom he did not support in last year’s election."
