Cornerstone Pipeline & Utica Build-Out Projects Binding Open Season

Notice of Binding Open Season
February 9 – March 13, 2015
Extended to April 13, 2015

Marathon Pipe Line LLC (MPL) and Ohio River Pipe Line LLC (ORPL), subsidiaries of MPLX LP (NYSE: MPLX), have announced an extension of the binding open season to assess interest and solicit commitments from prospective shippers for transportation service on the Cornerstone Pipeline and other associated Utica Shale build-out projects.

The proposed Cornerstone Pipeline will originate in Harrison County, Ohio and deliver to Marathon Petroleum Company LP's (MPC) Canton, Ohio refinery and to ORPL’s East Sparta, Ohio tank farm.  The Cornerstone Pipeline is being designed as a 16” diameter pipeline system that will be routed to provide the opportunity for connections to various Utica Shale condensate stabilization facilities, fractionator facilities, cryogenic facilities, along with potential future gathering and storage facilities.  The Cornerstone Pipeline will be a batched system with the ability to transport condensate, natural gasoline, diluent and butane. The estimated in-service date for the Cornerstone Pipeline is anticipated to be late 2016.

Cornerstone Pipeline – Connecting Utica Production 

MPL, as operator of ORPL, is also advancing various Utica Build-Out Projects to provide service to additional markets beyond Canton, Ohio.  The Cornerstone Pipeline will deliver volumes into the East Sparta tank farm for transportation to additional markets via the Utica Build-Out Projects, which include new construction and utilization of existing pipelines.  These projects connect many of the Midwestern refineries to the Utica Shale production and ultimately provide the ability to reach the Chicago, Illinois area refineries and pipelines that supply diluent to Western Canada. The estimated in-service date for all of the Utica Build-Out Projects is anticipated to be mid-2017.

Utica Build-Out Projects – Delivering Utica Production

 “The Cornerstone Pipeline and associated Utica Shale build-out projects will allow MPLX to provide transportation solutions from the Utica Shale area to a wide range of markets,” said Pamela Beall, MPLX president.  “This open season offers multiple pipeline options leveraging new and existing pipelines to meet the needs of various producers and end users.”

The binding open season began at 8 a.m. EST on Feb. 9, 2015 and has been extended to conclude at noon EST on Apr. 13, 2015.
