MPLX, i.e. MarkWest Energy, has been slapped pretty hard by the federal Environmental Protection Agency, Pennsylvania Dept. of Environmental Protection, and several other state environmental agencies. Last Thursday the federal EPA serving as lead agency, announced a settlement with MPLX (and its various subsidiaries) to pay nearly $7 million in fines and corrective actions to cut down on air emissions at 21 of its plants in Pennsylvania, Ohio, West Virginia, Kentucky, Texas and Oklahoma. Of that total, $925,000 is a fine or “penalty” for violating clean air laws at the plants. The rest of the money will be spent on corrective actions to fix things and cut down on air emissions.
