"The U.S. Environmental Protection Agency will order wastewater disposal wells shut near the epicenter of a 5.6 magnitude earthquake that struck on Saturday around Pawnee, Oklahoma, local media reported on Tuesday.
The quake was one of the strongest ever to hit the state and prompted its oil and gas regulator, the Oklahoma Corporation Commission, to order 37 disposal wells shut in a 725-square-mile (1,878-sq-km) area around Pawnee.
It also asked the EPA to help shut disposal wells in a 211 square-mile (546.49-sq-km) area of Osage County because the OCC lacked jurisdiction there."
