Authorities allowed the company to resume work after corrective actions.

The state Department of Environmental Protection announced on Thursday that it has fined Cabot Oil and Gas $56,000 for three polluting spills at one of its natural gas drilling sites in Susquehanna County.

The fine comes a little more than a month after the spills, which all occurred within a week of each other at the Heitsman well in Dimock Township and totaled about 8,400 gallons of fluids. Some of the liquid, which was a mix of mostly water and a gel that facilitates the drilling process, drained into an adjacent wetlands and Stevens Creek.

“The department presented a number to us and we thought under the circumstances that it was appropriate and not something that we wanted to fight about,” said Ken Komoroski, Cabot spokesman. “We’re just going to move forward.”

Within a few days of the spill, DEP ordered Cabot to halt hydraulic fracturing – the process that caused the spills – and submit an engineering analysis about what went wrong and how it will be avoided in the future.

Cabot’s report said the failure was caused by pressure surges and that significant elevation differences between where the liquid was stored and where it was being pumped to contributed to the problem.

The report includes a list of corrective actions that Cabot has agreed to take, among them providing better containment and pressure-regulating valves for sites where elevation is a factor.

DEP approved the report on Oct. 16 and allowed Cabot to resume “fracking.” The process forces water, sand and a mix of chemicals into the rock layer that contains the gas, causing fractures that release the gas up the well.

Gas drilling has boomed in the Northern Tier since fracking and horizontal drilling technologies have made it financially feasible for companies to drill into the Marcellus Shale, a layer of gas-laden rock that runs about a mile underground from New York into Virginia.

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.

About 8,400 gallons of a gel used in drilling natural-gas wells was spilled on Wednesday at a well being drilled in Dimock Township for Cabot Oil & Gas, the state Department of Environmental Protection announced Thursday.

Spilled at the Heitsman well site, the substance affected an unknown amount of “shallow wetland,” said company spokesman Ken Komoroski.

DEP and state Fish and Boat Commission officials were on hand Wednesday and Thursday as a crew cleaned up and contained the material, said DEP spokesman Mark Carmon. It may have gotten into Stevens Creek, he said.

“What was done was the spilled material was immediately contained” using an eight-man crew, Komoroski said. “The gel was able to be removed by vacuum trucks.”

The spill occurred as Halliburton was using a fluid to fracture the Marcellus Shale and release the natural gas within it, he said. Baker Tank, the contractor responsible for tanking and piping for the “frack” job, allowed a pipe to come loose and release the gel, he said.

“This is certainly disappointing to Cabot that this occurred,” Komoroski said. “On the other hand, these are the types of things that are typically unforeseeable and it’s important to react to it when it occurs.”

The slippery substance is “relatively innocuous,” he said, but “does have the potential for eye, skin and respiratory irritation.” Used to help suspend sand particles evenly throughout the so-called fracking fluid, it’s made of “paraffinic material” and polysaccharides, or something like fluid wax and starch.
