EPA involved in 2014 pipeline leak investigation

MANDAREE – The Environmental Protection Agency is investigating whether Crestwood Midstream violated the Clean Water Act last year when a pipeline spill leaked about 1 million gallons of brine on the Fort Berthold Indian Reservation.

The EPA has issued Crestwood Midstream and Arrow Pipeline a Notice of Potential Violation for the July 2014 pipeline spill near Mandaree.

The notice states that the brine flowed in a stormwater ditch and then a ravine before entering an unnamed tributary and traveling about a mile north through a series of beaver dams before reaching Bear Den Bay of Lake Sakakawea. Lake Sakakawea and its tributaries are waters of the United States.
