Marathon Oil agreed to spend $241.5 million to resolve federal allegations that it unlawfully emitted methane, a planet-warming greenhouse gas, and other pollutants from oil and gas facilities in North Dakota.
Under the proposed settlement announced on Thursday, the oil and gas producer, based in Houston, would pay a $64.5 million civil penalty.
The federal government said it was the largest-ever fine for alleged violations of the Clean Air Act that took place at stationary infrastructure.
The settlement is part of a wider effort by the E.P.A.
to rein in greenhouse gas emissions at oil and gas facilities.
