The West Whiteland Township Board of Supervisors sent letters to the US. Department of Transportation's Pipeline and Hazardous Materials Safety Administration (PHMSA) and to the Pennsylvania Public Utility Commission (PUC) seeking information about Sunoco's plans to repurpose an existing 12” pipeline to transport natural gas liquids. The 12" pipeline previously carried refined petroleum products but has not been in use recently in West Whiteland. In June 2018, Sunoco notified PHMSA of their plans to repurpose that pipeline to carry natural gas liquids as a way to allow Sunoco to meet its customer obligations on the Mariner East 2 pipeline while work on the Mariner East system continues, including the re-evaluation of existing construction plans
for some of the horizontal directional drills; and to make any appropriate modifications. When construction is completed, the 12-inch line will be returned to refined products service. When construction is completed, Sunoco plans to return the 12-inch line to refined products service. Sunoco also provided information about this proposed changed to the Township.
The Board of Supervisors would like more information about the regulatory review process at the federal and state levels such as: What approvals are needed? And, if the pipeline is repurposed, what what steps would be taken to ensure it could safely operate at high pressure carrying natural gas liquids so close to homes, businesses and gathering places such as schools and churches?
