Ohio regulators link fracking to earthquakes
COLUMBUS - Regulators in Ohio say they have liked earthquake activity in the eastern part of the state to hydraulic fracturing.
State Oil & Gas Chief Rick Simmers says the state has halted drilling indefinitely at a site near Youngstown where five minor tremors occurred in March. It follows an investigation finding a probable link to fracking.
A deep-injection well for fracking wastewater was tied to earthquakes in the region in 2012.
Simmers says Ohio will require sensitive seismic monitoring as a condition of all new drilling permits within three miles of a known fault or existing seismic activity. Any tremor of 1.0 magnitude will call for drilling to pause for evaluation.
