[10] Regulators in Oklahoma ordered 37 wastewater disposal wells in the vicinity of the earthquake (see map in citation) to be rapidly closed.

[11][12] Oklahoma Governor Mary Fallin declared a state of emergency for Pawnee County where the worst of the damage was located.

[13][14] Thirty-two additional wells were shut down by the Environmental Protection Agency because they were determined to be located too close to the newly discovered fault on which the earthquake occurred.
