The proposed Mariner East 2 pipelines are a pair of large diameter hazardous, highly volatile liquids (HVL) lines that if constructed, ME2 would transport hazardous highly volatile liquids such as ethane, propane, and butane from Marcellus Shale region to Marcus Hook for refinement and export.

 

These products remain liquid under high pressure, but in the event of a leak, vaporize upon contact with air, forming an invisible, odorless, and extremely combustible gas cloud.

 

The proposed pipeline would traverse 11.5 miles of Delaware County in close proximity to schools, parks, residences, and other vulnerable sites is a concern for area residents and leaders.
