420 gallons of oil from cracked pipeline reaches rangeland
KILLDEER, N.D. (AP) — A small percentage of the crude oil from a cracked pipeline in Dunn County earlier this week found its way onto rangeland, state officials said Thursday.
The state Department of Environmental Quality said about 420 gallons of the 10,500-gallon spill flowed into grasslands about 11 miles northwest of Killdeer. Bridger Pipeline LLC reported the incident when it happened on Tuesday, officials said.
Officials on Thursday also confirmed a 8,400-gallon produced water spill at a saltwater disposal facility in McKenzie County. About 42 gallons of the liquid reached a frozen creek, officials said.
The incident at the the White Rock Oil & Gas, LLC site 12 miles northwest of Grassy Butte was reported when it happened Wednesday. The cause of the spill was pump failure that led to a tank overflow, officials said.
Produced water is a byproduct of oil extraction and is typically taken from a well to a disposal site, where it is injected back into the ground for permanent storage.
Department of Environmental Quality workers are inspecting both sites and monitoring cleanup operations.
