SemGroup Corp. (NYSE: SEMG) and DCP Midstream LP (NYSE: DCP) have extended the binding open season by one week for NGL transportation service from the DJ Basin to Mont Belvieu, Texas, the company said on June 25.

The transportation capacity is available via a soon-to-be converted portion of White Cliffs Pipeline and Southern Hills Pipeline, connecting Weld County, Colorado to Mont Belvieu, Texas. The project, which is expected to be in service in the fourth-quarter of 2019, will provide DJ 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 66% of Southern Hills Pipeline and is the operator.

Shippers will move product under a published joint tariff between the two carriers. The open season is being held to provide prospective shippers an opportunity to receive discount transportation rates in exchange for long-term volume commitments.

Open Season began May 24, 2018, and will now conclude at 5 p.m. CT on July 2, 2018.
