Pipeline Launcher/Receiver Emissions Reduction Systems

Overview

MPLX LP, through its subsidiaries MarkWest Liberty Midstream & Resources, L.L.C. and Ohio Gathering Company, L.L.C., has entered into a first-of-its-kind agreement with the U.S. Environmental Protection Agency, the Commonwealth of Pennsylvania and the U.S. Department of Justice to implement design and operating improvements at pipeline launcher and receiver stations. As a result of these best management practices, emissions from these operations are expected to be reduced by as much as 85%. As part of the agreement, we are sharing our proprietary designs for “pig ramps” to minimize liquid loss during pig retrieval and information on the installation of de-pressure systems to reduce the pressure in the launcher/receiver chamber prior to opening.

Information on the designs is available here.
