Two public hearings for oil and gas infrastructure are on the horizon in the area, both of them involving conversions of existing pipelines to new purposes.

Hess is seeking to convert 19 miles of 10-inch and 16-inch crude oil gathering lines in McKenzie County into a transmission line. Since it is a conversion, ground disturbance would be minimized, the company’s application for the necessary permits notes, but three booster pumps would be added in three different locations.

The new transmission line would have a normal throughput of 100,000 barrels per day, and a maximum capacity of 160,000 barrels per day. The estimated cost of the conversion is $107 million.

The new line will take oil from storage tanks at Hess’ existing Hawkeye Oil Facility and take it to the Dakota Access Pipeline terminal. It will also transport crude oil from the existing Crestwood Arrow Facility.

The gathering lines were originally built to take oil to Hess Midstream production facilities, including the Ramberg Truck facility and the Tioga rail Terminal. But the transport of crude from Hawkeye to these facilities would have required transporting crude oil under Lake Sakakawea. This avoids the need for a permit under the lake, which the company said in its application was difficult to get.

The hearing for the Hess conversion project is 9 a.m. CST April 10 at Teddy’s Residential Suites in Watford City.

The other conversion project is for ONEOK Rockies MIdstream. They want to convert an existing gathering pipeline and a portion of another gathering pipeline into a 45-mile transmission line that would carry 50,000 barrels per day of y-grade NGLs from the Lonesome Creek Plant to the Stateline Plant, where it would deliver into the Bakken Pipeline.

The additional takeaway is needed to help reduce flaring, the company said in its application.

The new line would be called the Cherry Creek Lateral. It’s estimated cost is $1.8 million.

A hearing on the Cherry Creek conversion project had been scheduled for March 9, but was cancelled due to weather. The new date of the new hearing is 9 a.m. April 12 at the Ernie French Center in Williston.
