Arrests near Mariner East pipeline just latest incident of intimidation, witnesses say

In the latest incident pitting Mariner East pipeline builder Energy Transfer/Sunoco against those who oppose the pipeline project, Uwchlan Township police arrested a Lancaster County couple on Wednesday, charging one with trespassing and the other with disorderly conduct.

Those who live along the pipeline path say the tactic has been used repeatedly by the pipeline company: call local police and report trespassing on easements that run through backyards, parks and roads in densely populated Chester and Delaware counties.

Carrie Gross, a resident of Uwchlan Township, Chester County, who was leading a tour of Mariner East construction sites with six other people, said Energy Transfer, which now owns Sunoco, exploits local police departments to intimidate pipeline opponents from documenting construction that has led to sinkholes, drilling mud spills, and contaminated drinking-water wells.

“Sunoco just continues to intimidate residents,” said Gross. “They waste our police resources on things like this. They take our pictures, they take pictures of our cars, they follow us. They are not good neighbors.”

Earlier this month, the Chester County district attorney flipped the pattern and went after Energy Transfer’s security team, charging it with bribery in illegally hiring state constables to guard construction sites while carrying badges and guns.

“There’s a very clear line that has to be drawn between law enforcement who is acting for the public good, and the public good alone, and the corporate employee who is acting for the good of the organization,” District Attorney Tom Hogan said at the time. “You cannot mix those two together.”

Hogan charged an Energy Transfer employee, along with employees from the security firm TigerSwan and the owners of a Harrisburg security firm, Raven Knights. The indictment says Energy Transfer funneled payments to the constables through a number of third parties in order to hide their involvement.

In this week’s incident, Gross said, the arrests happened after she took a group of people on a tour of pipeline construction, which she says she has done several times for elected officials and journalists. She said Energy Transfer/Sunoco employees approached them at a construction site on Devon Drive.

A protest took place on Devon Drive last April. But Gross said that on Wednesday, there was no protest or plans to disrupt construction.

“We were on the sidewalk, we weren’t blocking anything, and we told them that if they needed us to move, we would,” said Gross.

Mark Clatterbuck, a religion professor at Montclair State University and resident of Lancaster County, said part of his foot touched gravel on the pipeline easement. Gross said that when he was told to move his foot, he did immediately and the group left soon after in her car.

After driving for about a mile, Gross said, she was surprised to be pulled over by Uwchlan Township Police Sgt. Philip Owen.

Gross said Owen implied that Energy Transfer reported that the group had blocked the pipeline. Soon, she said, two other police cars showed up, along with a Sunoco employee who had been on the construction site. An Uwchlan police officer pulled Mark Clatterbuck out of the back seat and cuffed him. He was later charged with trespassing.

His wife, Malinda Clatterbuck, said that she jumped out of the car to film the interaction, but was ordered back in the car, and that when she refused, she too was cuffed and arrested. She was charged with disorderly conduct.

The charges are summary citations, the equivalent of traffic tickets.

Uwchlan Township Police refused to answer any questions about the incident, or their relationship with Energy Transfer.

Malinda Clatterbuck, who is a pastor at the Community Mennonite Church of Lancaster, said she and her husband had protested against the Atlantic Sunrise pipeline. Some of those protests included planned civil disobedience, where she says she expected to be arrested. But that wasn’t the case on Wednesday.

“Law enforcement is used to intimidate people who live there,” she said. “It’s not against the law to oppose the pipeline.”

State Rep. Danielle Friel Otten said she worries that incidents like this could drive a wedge between the community and the police. She said she doubts there is any formal relationship between the Uwchlan Township Police and Energy Transfer.

“We have always had an incredibly positive relationship with our police department here in Uwchlan Township,” said Friel Otten.“I do believe that Energy Transfer does this to send a message to the community that there will be serious consequences if we resist them, and that’s not OK.”

Friel Otten said she’s concerned that the employee from Energy Transfer followed in his car and was present during the arrest.

Gross said the incident both surprised and shook her up.

“They’ve been in our community causing a disturbance for two and a half years,” said Gross, “and they’re trying to make us look like the bad guys.”

On Friday evening, Energy Transfer spokeswoman Lisa Coleman said in an email that she was not aware of the details of the incident.

“However, what I can tell you is that our contractors abide by safety procedures that govern an active construction site —for their safety as well as the safety of others,” Coleman said. “We have a code of conduct that governs our employees, contractors and businesses and expect all to adhere the standards therein.”
