YOUNGSTOWN, Ohio – MPLX’s Cornerstone Pipeline project is expected to get under construction in the next several weeks, in time to meet its in-service date of late 2016, according to an oil and gas trade journal.

The trade publication North American Oil & Gas Pipelines reports that the rights-of-way have been cleared and construction on the 50-mile stretch of pipeline in Ohio should begin this month.

MPLX, a division of Findlay-based Marathon Petroleum Co., was formed in 2012 to develop and acquire midstream infrastructure such as pipelines and facilities that transport and process oil and natural gas. Last year, MPLX acquired MarkWest Energy Partners, which operates fractionation and cryogenic plants across the Marcellus shale in Pennsylvania and the Utica shale in Ohio.

The pipeline is expected to run 50 miles north from a MarkWest condensate operation and a Utica East Ohio fractionation plant in Scio, Ohio, in Harrison County to a Marathon Pipe Line LLC tank farm in East Sparta, and then to a Marathon Petroleum refinery in Canton.

MPLX announced the project in 2014. The company is also planning other build-out initiatives related to the Cornerstone project, such as connecting the MarkWest Hopedale fractionation plant to the pipeline and expanding its pipelines from East Sparta to Heath, Ohio, and then to Findlay.
