Statement: DEP Approves Modifications for Mariner East Construction in Cheso, Delco

The Pennsylvania Department of Environmental Protection (DEP) today approved modifications to construction methods used at several sites along the Mariner East pipeline project. The modifications address changes to pipeline installation methodology at two locations in Chester County and one in Delaware County.

If you are writing about the DEP approval, please feel free to attribute the following statement to Kurt Knaus, spokesman for the Pennsylvania Energy Infrastructure Alliance:

“DEP’s approval to get back to work at these sites is a positive sign for the project. These sites are two of the final construction locations remaining across the 350-mile 16-inch line and remain key to project completion. Modifying construction methods at these sites is critical to protecting the local environment and ensuring worker safety based on engineering and geological realities in the field. Today’s announcement is further proof that DEP, local communities, and the industry can come together and do what is right for both the local environment while also ensuring that critical infrastructure projects move forward to benefit Pennsylvanians.” 


For more than five years, the Pennsylvania Energy Infrastructure Alliance has advocated for the safe, responsible development of critical infrastructure. For more information:
