The Pennsylvania Department of Environmental Protection is holding up a pipeline project to force a company to fix problems related to a different gas pipeline that runs across Butler County.

In September, a section of Energy Transfer's Revolution Pipeline exploded in Beaver County, destroying a home and garage. The same pipeline cuts through much of Butler County.

The DEP issued a compliance order to the natural gas company in October following an investigation, according to a news release. To date, DEP investigators have found that the company “had not fulfilled the terms of the order and was not progressing toward compliance.”

On Friday, the DEP pulled another pipeline, the Mariner East 2 Pipeline, into the situation.

Neil Shader, a spokesman for the DEP, said that pipeline is owned by Sunoco, a subsidiary of Energy Transfer. The company has “over two dozen modifications and other approvals” needing processing, he said, and all are being put on hold until the company addresses problems with the Revolution Pipeline.

The explosion, he explained, resulted in significant erosion damage to a few streams and waterways — which is considered pollution. It also caused some land destabilization, which can lead to landslides. The DEP's October order demanded that steps be taken to mitigate those problems.

The DEP stated in its initial order that it could employ a civil penalty of $10,000 a day for each violation.

“We haven't issued any civil penalties, which does not preclude us from doing so in the future,” Shader said.

The Revolution Pipeline has not been in use since the September explosion.
