Waste-water injection well caused 12 earthquakes in Ohio, investigation shows
CLEVELAND, Ohio -- 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 round of new permitting rules for injection well drilling that could limit or slow down the number of new injection wells as contractors scramble to comply with tougher rules.
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.
