The company estimates the project to cost $100 million and to be operational by the fourth quarter of 2020.

North Dakota state regulators have approved ONEOK's plans to construct a 75-mile pipeline lateral connecting the northern portion of the Bakken NGL Pipeline with a third-party natural gas processing plant in eastern Williams County, North Dakota.

Oneok spokesman Brad Borror said the project is scheduled to move forward as planned, though the company has modified some of its other plans for a processing facility and pipeline in the Bakken in light of the recent oil price collapse.

Oneok says 58% of the new pipeline will be located alongside existing infrastructure which "really mitigated any additional environmental or cultural resources concerns that might come up with a pipeline of this length,” Fedorchak said.

The pipeline is expected to carry up to 90,000 bpd of natural gas liquids from the company’s Stateline-to-Riverview pipeline system to Hess Tioga Natural Gas Processing Plant.

The lateral will provide access to raw feed NGL pipeline takeaway in an area of Williams County with historically limited transportation options and will provide connectivity with key NGL market centers.

ONEOK says it has acquired nearly 75% of the necessary waivers and rights-of-way and will secure the outstanding waivers before beginning construction.

The North Dakota Public Service Commission approved the project on April 1.
