TRIADELPHIA, W.Va. -- State regulators have approved an air quality permit for a natural gas drilling site in Ohio County.

The permit issued by the Department of Environmental Protection will allow Chesapeake Energy to emit carbon monoxide, methane, formaldehyde and other chemicals from its Dytko drilling pad.

 The Intelligencer and Wheeling News Register says Chesapeake has announced in legal advertisements that it plans to release similar emissions from compressor stations and three other drilling pads in the region.

The Dytko site permit was opposed by a doctor who lives near the drilling pad. Dr. Michael Blatt filed an objection with the DEP saying about 100 people live within 3,000 feet of the pad, including families with young children.
