Spills bring violation notice to company

The initial events polluted a wetland and caused a fish kill in Susquehanna County.

Cabot Oil and Gas has been issued a letter of violation for two liquid-gel spills last week at the company’s Heitsman natural-gas well pad in Susquehanna County, the state Department of Environmental Protection announced on Tuesday.

The spills of about 8,400 gallons, which polluted a wetland and caused a fish kill in Stevens Creek, were followed up by a third spill at the site on Tuesday morning, according to DEP spokesman Dan Spadoni.

A hose burst, according to DEP, and released about 420 gallons of the same lubricant. A catch basin retained most of it, Cabot spokesman Ken Komoroski said, but it’s unknown what happened to 10 gallons.

He said he was unaware of the spills causing any environmental damage, but acknowledged that a dam created to block the contaminant caused flow problems and that DEP noticed “the minnows downstream were distressed and/or swimming erratically.”

“We think that it’s important to residents that no contaminants from the spill have compromised Stevens Creek,” he said.

The spilled material, known as LGC-35, suspends sand in water to fracture rock in the gas-drilling process used in the Marcellus Shale region.

LGC-35 is a “potential carcinogen,” according to its Material Safety Data Sheet, and can cause eye, skin and respiratory irritation, along with “central nervous system effects,” such as dizziness and headaches.

Komoroski said the drilling contractor, Halliburton, has since revised the safety sheet to exclude the carcinogenic reference because the potential cancer-causing agent is a “potential contaminant” to the gel, not part of its formula. Halliburton told Cabot the contaminant wasn’t present in the spilled batches, but Cabot is performing its own testing to confirm that, Komoroski said.

He added that Cabot feels Halliburton should have been cited for the spill. Halliburton had flushed the wetlands with clean water and collected the effluent before the third spill, Spadoni said, and it won’t be known whether the land needs to be excavated until results from soil samples are announced. “I would anticipate that would be done fairly soon,” Spadoni said.

Cabot has 10 days to respond to the violation notice with how it plans to further clean the affected area and prevent future spills. DEP may assess a civil penalty in the case, for which Komoroski said Cabot would seek compensation from Halliburton.
