Marathon Pipe Line LLC Announces a Successful Binding Open Season for the Patoka to Lima Expansion Project

FINDLAY, Ohio, Jan. 14, 2015 - Marathon Pipe Line LLC (MPL), a subsidiary of MPLX LP (NYSE: MPLX), is pleased to announce the completion of a successful open season for the expansion of the Patoka, Ill. to Lima, Ohio crude oil pipeline system. Based on the execution of a long-term binding agreement, MPL has the requisite support to continue development and commence construction of the expansion to accommodate the committed volumes.

"The Patoka to Lima pipeline expansion will allow MPLX to provide enhanced access to the growing crude oil supply available in the Patoka hub," said Pamela Beall, MPLX president. "That includes Bakken, Canadian, U.S. Midcontinent and Gulf Coast production."

As previously announced, the project will expand the current system capacity by an additional 18,000 barrels per day of light equivalent crude oil capacity through the system.  The project involves construction of two new pump stations and the injection of flow improver to optimize hydraulic performance of the pipeline system. The expansion is anticipated to be in-service in late 2016.
