OKLAHOMA CITY- The Oklahoma Corporation Commission is taking more steps to limit activity around wastewater disposal wells in Cushing.

This move comes after  several new earthquakes in that region have occurred.

This new move, according to the Commission, is to reduce the risk of induced earthquakes in the area by changing how specific wells operate.

Thirteen disposal wells will have immediate changes, and another 13 wells have been put on notice that changes may be coming.

For independent petroleum geologist Bob Jackman, the concern over quakes spreads far beyond Cushing's city limits.

Jackman is now calling on the Corporation Commission, to shut down all disposal wells within 20-25 miles of areas rattled by quakes over the decade.

These new 'zones' would include the areas surrounding Medford, Perry, Stillwater, Edmond, Guthrie, and Cushing.

"I think it'll be up to citizens to demand it. If they wait for legislation, that's too slow," said Jackman. "The proof is in the pudding, the number of earthquakes keeps increasing."

Here is a breakdown of the disposal wells affected by Monday's announcement:

Wells within 3 miles: Shut in (stop operations)

Wells within 3 – 6 miles: Reduce volume injected by 25 percent

Wells with 6 – 10 miles: On notice to prepare for possible future changes in operation.
