Waste-water injection well caused 12 earthquakes in Ohio, investigation shows
"A waste water injection well induced the series of 12 earthquakes in Youngstown last year, an on-going state probe has concluded.
And because of that, Ohio regulators on Friday unleashed a series of new permitting rules for well drilling that will probably limit the number of new injection wells drilled in the state.
The regulations come on the eve of an expected boom in gas and oil drilling in the state -- a boom that will also produce millions of gallons of naturally occurring salt water and chemically-laced water used to fracture shale containing the gas and oil.
In a 24-page preliminary report of its investigation into the quakes, the Ohio Department of Natural Resources has included a series of new permit requirements that it says go well beyond national standards."
