BISMARCK, N.D. (AP) — Crosswood Equity Partners has paid a $49,000 fine to the Environmental Protection Agency for a pipeline leak in 2014 that spilled 1 million gallons of produced water on the Fort Berthold Reservation and contaminated Lake Sakakawea.
The EPA also ordered Crestwood to provide the Mandan, Hidatsa and Arikara Nation with at least $173,000 in spill-response equipment.
Cleanup efforts are ongoing at the site near Mandaree. Crestwood is following an EPA-approved remediation plan that requires the company to install five groundwater monitoring wells.
The company estimates the pipeline leaked for five days before the spill was discovered in July 2014.
The spill traveled through a ravine, with about 10,500 gallons of produced water, a waste byproduct of oil production, reaching Bear Den Bay of Lake Sakakawea.
