An estimated 60,000 gallons of jet fuel and kerosene spilled from a Sunoco pipeline in Upper Merion Township on Thursday, Nov. 5, after a drilling crew struck the line while installing electric towers for PECO.

The spill triggered a hazmat response, a shelter-in-place order and road closures along River Road in the Bridgeport section of the township in Montgomery County.

Upper Merion Police Chief Blaine Leis told 6abc that a third-party contractor drilling for new electric towers hit a 14-inch pipeline carrying jet fuel around 3 p.m. Sunoco shut the pipeline down after being contacted, according to Leis.

"That jet fuel was escaping out of the hole onto the parking lot, and then down across the property," Leis said, according to 6abc.

The fuel flowed onto the property of Insurance Auto Auction on River Road and into the adjacent Glasgow Quarry, according to multiple reports. Leis said the spill was contained to those two properties.

No injuries were reported.

State Rep. Tim Briggs, whose 149th District includes Bridgeport and Upper Merion, said late Nov. 5 that most of the fuel flowed into Glasgow Quarry and away from the Schuylkill River, according to Patch. The 60,000-gallon figure is a preliminary estimate, Briggs said.

The extent of environmental damage is not yet clear, Patch reported. The Pennsylvania Department of Environmental Protection (DEP) and the Environmental Protection Agency (EPA) set up air monitoring at the scene, Daily Voice reported.

The quarry owner asked the DEP and cleanup crews not to enter the site until Friday morning, Nov. 6, for safety reasons, according to Patch. Lewis Environmental Group, based in Royersford, responded to help with cleanup along with crews from across Montgomery County, 6abc reported.

Township officials lifted the shelter-in-place order by about 5:19 p.m. Nov. 5, Daily Voice reported. Road closures on Route 23 between East 4th Street and B Street were lifted shortly after 6 p.m., according to 6abc.

PECO said in a statement that the contractor who struck the pipeline was working on the utility's behalf. No PECO electric or natural gas customers were currently affected, the company said. PECO crews remained on site to coordinate with Energy Transfer, according to the company's statement reported by 6abc.

The name of the third-party drilling contractor has not been released. No timeline for how long the quarry cleanup will take has been made public.
