DENVER—Meritage Midstream Services II LLC June 10 announced its subsidiary, Thunder Creek NGL Pipeline LLC, will launch a binding open season to secure volume dedications to support the proposed construction and development on its existing NGL pipeline to facilitate transportation of NGL from two processing plants located in Campbell and Converse counties in Wyoming to an interconnection point with ONEOK Hydrocarbon LP’s ONEOK Bakken Pipeline, LLC in Converse County, Wyo.

The binding open season commenced June 10 at 8 a.m. Mountain Time and is scheduled to conclude at 5 p.m. Mountain Time on July 10.

The open season seeks to obtain volume dedications from shippers to the following proposed new movements:

1. Originating from Thunder Creek Gas Services LLC’s 50 BuZes Process Plant in Campbell County, Wyo. with a destination at an interconnection with ONEOK Bakken Pipeline in Converse County; and

2. Originating from TCGS’s Steamboat I Natural Gas Plant in Converse County, with a destination at an interconnection with ONEOK Bakken Pipeline in Converse County.

The proposed new origin and destination points will allow potential shippers to move product from TCGS plants in the Powder River Basin to a newly established interconnect with ONEOK Bakken Pipeline LLC at Well Draw in Converse County, providing potential shippers the ability to access ONEOK’s Niobrara Lateral, which will ultimately access newly created capacity on ONEOK’s Elk Creek expansion.

Subject to shipper demand, required new infrastructure to enable the proposed new movements is expected to be completed in third-quarter 2019.

The binding open season process provides potential shippers with the opportunity to obtain firm capacity on the proposed new movements by making deemed volume commitments to Thunder Creek during the binding open season. Shippers that elect to execute transportation services contracts and make commitments to Thunder Creek during the binding open season will receive firm capacity rights up to an amount equal to each shipper’s elected deemed volume commitment.
