Pennsylvania Failing to Sanction Drillers for Fracked Well Failures

For the past several years, the shale gas industry has argued that oversight of fracking is getting tighter and that the amount of methane gas leaking from their wells is less than some have speculated.

In Pennsylvania, however, the opposite is true, according to a white paper delivered to New York state regulators by Cornell engineering professor, Anthony Ingraffea. Inspection data from the state indicate that over 150 Marcellus shale wells in Pennsylvania had severe flaws that have led to sometimes large leaks and yet the operators of those wells were never issued violations by regulators for these breaches of state law.
 
By failing to cite drillers when things go wrong, Pennsylvania environmental regulators have for the past three years obscured the rate at which Marcellus wells leak, creating a falsely optimistic picture. Leaks at dozens of wells were described by state inspectors in their report notes, but violations were never issued.
