Fracking regulations tighten in Ohio as earthquake link is made.

Guardian: “State geologists in Ohio have for the first time linked earthquakes in a geologic formation deep under the Appalachians to gas drilling, leading the state to issue new permit conditions in certain areas that are among the nation’s strictest.”
“A state investigation of five small tremors in the Youngstown area, in the Appalachian foothills, last month has found the high-pressure injection of sand and water that accompanies hydraulic fracturing, or fracking, in the Utica Shale may have increased pressure on a small, unknown fault, said State Oil & Gas Chief Rick Simmers. He called the link “probable.”
While earlier studies had linked earthquakes in the same region to deep-injection wells used for disposal of fracking wastewater, this marks the first time tremors have been tied directly to fracking, Simmers said. Five seismic events in March were all part of what was considered a single event and couldn’t be easily felt by people.
….Under the new permit conditions, all new drilling sites in Ohio within 3 miles of a known fault or seismic activity of 2.0 magnitude or higher will be conditioned on the installation of sensitive seismic-monitoring equipment. Results will be directly available to regulators, Simmers said, so the state isn’t reliant on drilling operators providing the data voluntarily.
….Ohio has also imposed an indefinite drilling moratorium at the site of the March quakes. The state is allowing oil and gas extraction to continue at five existing wells at the site.”
