Notice of Lodging of Proposed Consent Decree Under the Clean Air Act

On November 1, 2019, the Department of Justice lodged a proposed Consent Decree with the United States District Court for the Northern District of Ohio in the lawsuit entitled United States, et al. v. MPLX, LP, et al., Civil Action No. 3:18-cv-02526.

The United States filed this lawsuit against MPLX and eleven of its subsidiaries for violations of the Clean Air Act at twenty natural gas processing facilities in six states. The complaint alleges, among other things, that MPLX violated Leak Detection and Repair requirements of the Clean Air Act's New Source Performance Standards. The proposed Consent Decree requires MPLX and its subsidiaries to take specified actions to come into compliance with the Clean Air Act, pay a civil penalty of $925,000, and undertake Supplemental Environmental Projects at a cost of $2,575,000. The Commonwealth of Pennsylvania and the States of West Virginia and Oklahoma have joined us in this action.
