Because West Whiteland Township did not have any regulatory authority over the repurposing of Mariner East 1 and has not had any regulatory authority over Sunoco’s proposed construction of Mariner East 2. West Whiteland Township does not have enforcement or regulatory authority over the location of underground transmission pipelines, or whether a pipeline is constructed by horizontal directional drilling or open trench construction, or the type of product that will flow through the new pipelines or any of the existing pipelines. To the extent there are regulations for underground transmission pipeline siting, methods of construction or use, they are enforced by federal and state agencies.
The Board of Supervisors has supported and advocated for pipeline safety. The Board funded a report to obtain recommendations for amendments to pipeline safety regulations, which was incorporated into comments by the Chester County Association of Township Officials submitted to the PA PUC. The Board endorsed those comments in their own letter to the PUC as part of a rulemaking process. In addition, the Board has intervened in three complaints before the PUC having to do with Sunoco's Mariner East pipelines.
