Ohio Utica Shale

Here's the full ODNR Youngstown earthquake report

Ohio says its new rules for brine monitoring and disposal will be among the toughest in the United States.

The new rules are resulting from an investigation by the Ohio Department of Natural Resources on a link between a Mahoning County injection well and a dozen earthquakes near Youngstown in the last year.

The state on Friday released a 24-page preliminary report that concludes that the earthquakes were triggered by injecting briny wastes from Pennsylvania's Marcellus shale  into the D&L Energy injection well in Youngstown Township.

The quakes stemmed from "a number of coincidental circumstances" including unknown geologic fault lines under the 9,000-foot-deep injection well,  ODNR said.

"our evidence strongly suggests that the injection fluid lubricated a previously unmapped fault and contributed to seismic activity," said ODNR spokesman Carlo LoParo. "It was an unfortunate situation and the operator drilled the well to specifications and operated within all permitted levels,"

The state agency outlined a number of steps to tighten regulations on injection wells.

Ohio currently has 176 operating injection wells.
