Whistleblower claims Mariner East construction lacks proper safety measures related to sinkholes, subsidence

In legal claim, professional geologist says Sunoco prevents proper inspections, edits reports on erosion

  • Susan Phillips

A professional geologist who worked on the Mariner East pipeline project says pipeline builder Sunoco/Energy Transfer prevented him and other geologists from inspecting and reporting on dangerous subsidence, or sinkholes, during construction.

The whistleblower says professional geologists were prevented from speaking to drillers, unable to gain access to drill sites, told to change the name from subsidence to “earth feature” in reports, and had their mandated reports to agencies like the Department of Environmental Protection edited and changed by non-geologists.

He says the company had what they called a “limited disturbance policy” whereby geologists should only report subsidence issues within a specific area. Failing to follow the policy would risk termination.

The claims are detailed in a notice of intent to sue Sunoco by the Clean Air Council. The legal notice was sent to the company on Tuesday. The whistleblower is not identified in the document.

Tim Fitchett, staff attorney for Fairshake Environmental Legal Services, is representing Clean Air Council in the case. Fitchett said Sunoco fired the geologist after he reported a sinkhole in Chester County that lay outside the area defined by the company’s “limited disturbance policy.”

Clean Air Council sued Sunoco in 2017, which resulted in a  settlement agreement with the company and DEP.

“Sunoco is so scared of what its scientists will find in investigating its pipeline construction that it’s muzzled them and doctored their reports,” said Joseph Minott, executive director and chief counsel of Clean Air Council.

Sunoco’s erosion and sediment control permits issued by the Department of Environmental Protection require the company to report subsidence and stop work until a plan is created and approved by DEP. But Fitchett said the geologist witnessed examples where work stopped for about a week, the subsidence was “cursorily” monitored, and reports issued to DEP claimed no issues. At that point, work would restart at the site.

Fitchett said the geologist saw issues similar to the kinds of subsidence that occurred in Beaver County at another Energy Transfer pipeline construction site, which led to an explosion in September 2018. No one was injured in the Revolution Pipeline incident, but it burned a house to the ground. Fitchett said the geologist decided to inform the Clean Air Council of his experiences due to safety concerns.

Chester County resident Eric Friedman, who opposes the Mariner East pipeline and is active with DelChesco United for Public Safety, said this is further evidence the pipeline should shut down.

“When the Revolution pipeline blew up… a house burned down but here we have elementary schools and a densely populated area,” he said.

Under Pennsylvania’s Clean Streams Law, a citizen suit requires 60-day notification to the defendant. During that period, Sunoco could reach an agreement with Clean Air Council to change its practices, or DEP could intervene in the case.

Neither DEP nor Sunoco/Energy Transfer would comment on the notice to file suit. Fitchett said both the DEP and the Pennsylvania Attorney General’s office are aware of the whistleblower’s claims. The Attorney General’s office also had no comment.
