Due to ongoing shipper interest, SemGroup Corp. and DCP Midstream LP have announced the commencement of a supplemental open season for NGL transportation service on the Wattenberg Pipeline, White Cliffs Pipeline and Southern Hills Pipeline, which will connect Weld County, Colo., to Mont Belvieu, Texas.

SemGroup is currently converting a portion of White Cliffs to NGL service and expects it to be in service in the fourth quarter of 2019. When combined with Southern Hills Pipeline, the system provides Denver-Julesburg (D-J) Basin customers with increased NGL takeaway capacity and open access to the Texas Gulf Coast markets.

SemGroup owns 51% of White Cliffs Pipeline and is the operator. DCP owns 100% of Wattenberg Pipeline and 66%of Southern Hills Pipeline, and is the operator of both pipelines.

Service will be provided under a published joint tariff between the two carriers. The open season will provide prospective shippers an opportunity to make long-term ship-or-pay volume commitments by executing transportation services agreements with White Cliffs and DCP, in exchange for incentive transportation rates. The terms and conditions of service being made available during this open season extension are the same as those made available to shippers during the initial open season held in May.
