HARRISBURG — Pennsylvania environmental regulators are fining Houston-based Cabot Oil and Gas for a storage tank explosion and wastewater spill at a gas drilling site.

The Department of Environmental Protection said Tuesday it fined Cabot $120,000 for the January incident at its Reynolds well pad in Susquehanna County.

Officials say vapors in the head space of the wastewater tank ignited and caused the Jan. 11 explosion, rupturing the tank. Inspectors found a worker checking the level of fluid in the wastewater tank ignited the vapors while using his cell phone as a flashlight.

The department says an employee was injured and more than 2,800 gallons of wastewater spilled, tainting soil beyond the well pad.
