“Mr. Shields said his review of zoning ordinances in 130 Allegheny County municipalities found 56 with no zoning ordinance specific to oil and gas drilling and development, while another 30 have zoning rules that are outdated because they don’t follow either current state law or recent court decisions, or both.
“Of the 56 municipalities without zoning that addresses oil and gas development, 31 already have acreage leased for gas extraction within their borders, according to the Allegheny County Lease Mapping Project developed by FracTracker Alliance, a nonprofit based in Camp Hill that maps and tracks risks related to oil and gas development. . . .
“’Where the gas industry is allowed to drill becomes a public safety issue,’ Mr. Shields said. ‘Washington has 250 people per square mile. Tioga County has 100. If there’s an explosion, what do you do about an evacuation? You can evacuate a square mile in Tioga with a school bus or two, but what do you do in Allegheny County?'”
