Emergency crews were called to the Chapin Dehydration Station, a natural gas processing plant along state Route 309, twice in the last two weeks.
On May 27, stacks above one of the station’s reboiler units vented steam, and it is believed a temperature drop in one of the unit’s pollution-control mechanisms caused the steam release, according to state Department of Environmental Protection spokeswoman Colleen Connolly.
The second incident happened around 1 a.m. Wednesday, and some neighbors reported hearing a “loud bang” from the station.
Regency Energy Partners, which operates the plant, told DEP it appears an air bubble in the system caused pressure to rise to the point it pushed through causing the sound.
Wyoming County emergency crews tested the air and found no gas had escaped. Residents living nearby stayed inside, no evacuations were necessary.
Regency workers are making repairs and are to report to DEP the details of both incidents following investigations, Connolly said.
A Regency spokeswoman said the company has experienced two “minor operational events” in the past two months, which were addressed quickly and without incident.
“In all aspects of our operations, safety is our top priority,” the spokeswoman said.
