The cross-state natural gas liquids pipeline Mariner East 2 was supposed to begin operation by the end of September. Now, the company has come up with a workaround after acknowledging another lengthy delay in its pipeline project.

The company missed its deadline of opening the line by the end of September. The Public Utility Commission said there are several issues with the project that still need to be resolved.
As part of the “Mariner East 2: At what risk?” series, StateImpact Pennsylvania reports how pipeline opponents say Sunoco’s construction makes them worried about the volatile liquids flowing through the line. The data can be useful, but there may be more to the story, two experts said.
Contamination has been found at sites including Montgomery, Bucks and Franklin counties. Pennsylvania doesn’t have health limits on the chemicals, and a Wolf administration spokesman said the governor wants the state to establish such limits.
The Delaware River Basin Commission said it thinks the company might want to start clearing trees before its project gets all necessary approvals. In part, the commission is worried about problems that could occur if the pipeline never gets built.
Companies are allowed to protect trade secrets, and the health risks of unidentified chemicals are unknown. Advocates push for disclosure, saying the public needs to know about the chemicals in order to help protect drinking water.
The study says a pipeline “release” such as a small leak or a major rupture was likely to occur once every 79 years along a 35-mile stretch of pipeline such as that through Chester and Delaware counties.
