MPLX Announces Binding Open Season, Proposing Expansion of SLC Core Pipeline System

Notice of Binding Open Season
Sept. 21 - Oct. 23, 2020

MPLX LP (NYSE: MPLX) launched a binding open season to assess shipper interest in firm priority capacity on the SLC Core Pipeline System, located in Wyoming, to transport crude oil from Fort Laramie Station, Wyoming, to Wahsatch Station, Utah. From Wahsatch Station, crude transportation service is available on a third-party system for ultimate delivery to refineries in the Salt Lake City, Utah, area.

The binding open season will commence on Sept. 21, 2020 and will end at noon CDT on Oct. 23, 2020.

About the SLC Core Expansion

The proposed SLC Core Pipeline System capacity expansion would provide shippers access to the Guernsey crude oil market hub and access to additional crude oil grades for refiners in the Salt Lake City area. The expansion would provide incremental pipeline capacity of approximately 11,000 barrels per day (bpd), reinstating origin service from Fort Laramie, Wyoming. This expansion would bring total capacity on the SLC Core Pipeline to approximately 56,000 bpd and is expected to begin service in the first quarter of 2022.
