Pipeline of brine spill not marked, ND officials say

WATFORD CITY, N.D. -- A pipeline struck during construction last week in McKenzie County caused a brine spill of 200 barrels, or 8,400 gallons, according to a statement from the North Dakota Department of Health released on Wednesday.

The spill occurred May 29 about 15 miles southeast of Watford City when a produced water pipeline was struck during installation of a water line, the health department said.

The company that struck the pipeline did call North Dakota One Call as required by law, but the pipeline was not marked, said Bill Suess, spill investigation program manager for the Department of Health.

The company is investigating why the pipeline wasn’t marked, Suess said.

The pipeline is part of a gathering system for a saltwater disposal facility owned by Hanna SWD, a subsidiary of Goodnight Midstream. The company reported the spill on May 30.

The produced water, a waste byproduct of oil and gas development, affected rangeland. A spill report indicates the landowner moved cattle to another pasture.

Health department personnel and the Oil and Gas Division have inspected the site and will continue to monitor the investigation and cleanup.
