An oil and gas company operating on the Ft. Berthold Indian Reservation will upgrade its systems to come in compliance with the Clean Air Act.
The U.S. Environmental Protection Agency and Department of Justice have announced a settlement with Slawson Exploration Company Inc. to resolve claims that Slawson “failed to adequately design, operate and maintain vapor control systems on its storage tanks at its approximately 170 oil and natural gas well pads in North Dakota, resulting in emissions of volatile organic compounds.”
Slawson will spend about $4.1 million on systems upgrades, including infrared cameras and electronic pressure monitors to better detect and respond to air emissions. Slawson must also fund $2 million in environmental mitigation projects and pay a $2.1 million civil penalty.
EPA estimates the system upgrades, many of which are already in place, will cut 11,700 tons of VOCs emissions, 400 tons of hazardous air pollutants, such as benzene, toluene, ethylbenzene and xylenes, and 2,600 tons of methane annually.
