Earlier this month, crews with Driver Pipeline Co. of Irving prep the right-of-way where the Sterling III pipeline is planned to cross U.S. 84 — about 5 miles west of the Palestine city limit sign. Motorists using the highway are urged to use caution when approaching this area. The Sterling III pipeline is a new 540-plus-mile, 16-inch diameter natural gas liquids (NGL) pipeline and is being built by Oklahoma company Oneok Partners. According to company officials, when complete, it will transport either unfractionated NGLs or NGL purity products from the mid-continent region to the Texas Gulf coast. It will have an initial capacity of 193,000 barrels per day (bpd) and the ability to expand to 250,000 bpd. It is currently on track to be completed by the end of the year.
