The Environmental Protection Agency (EPA) opened a Criminal Investigation Division (CID) office in North Dakota at the end of July. North Dakota has seen its oil production increase to over 1 million barrels a day over the last decade. The Bakken shale, located in the western part of the state, holds almost 11 billion barrels of oil, and production is increasing. EPA’s office is staffed by four agents who plan to investigate operations in the state’s western oil patch, ranging from drilling rigs to disposal sites and everything in between. EPA’s closest offices have been in Montana and Colorado making on-the-ground investigations in North Dakota challenging. Companies operating in North Dakota will likely see an uptick in scrutiny and an increased investigations from this in-state EPA CID presence.
