Ohio is poised for an energy boom -- if it adopts public policies to encourage development rather than over-regulate shale gas drilling, the industry's top oil spokesman said in a talk on Friday in Cleveland.
Ohio has "immense opportunities," said Jack Gerard, president and CEO of the American Petroleum Institute. He called Ohio's Utica shale a "game changer.".
But he cautioned that the state should not go too far in adopting new rules because that would discourage investment by the industry and the job-creating potential of the Utica shale would be lost..
His appearance at the City Club of Cleveland was his second appearance in Ohio in May.
He appeared earlier at an energy conference in Columbus.
His appearance comes as the Ohio Department of Natural Resources and the Ohio Legislature are taking steps to tighten Ohio's rules on hydraulic fracturing or fracking in drilling for natural gas and oil.
