HARRISBURG — Pennsylvania regulators are halting all gas drilling activities by the company whose natural gas well spewed out explosive gas and polluted water for 16 hours last week.

Gov. Ed Rendell said today the order against EOG Resources will remain in place until the Department of Environmental Protection can finish its probe and until after the company implements whatever changes may be needed.

The order stops EOG from drilling and fracking operations.

A blow-out of an EOG well in north-central Pennsylvania's Clearfield County on Thursday sent gas and at least 35,000 gallons of drilling wastewater into the environment.

The state agency says the company is being cooperative with the investigation and is supportive of the order.
