Mariner East 2 Pipeline Moves Forward

April 2017

The Pennsylvania Department of Environmental Protection has granted the permit applications from Sunoco Pipeline LP for the PA Pipeline Project/Mariner East 2 pipeline project. The DEP considered 17 Chp. 105 (Water Obstruction and Encroachment) permits and 3 Chp. 102 (Erosion and Sediment Control) permits for the project. Once completed, the pipeline will deliver natural gas liquids from southwest counties to Marcus Hook, in southeast Pennsylvania.

“I am proud of the immense undertaking our staff took to hold this project accountable within the confines of state law and DEP’s role in this process over the last few years,” said Acting DEP Secretary Patrick McDonnell. “This was a huge undertaking – holding five hearings during a 60-day comment period, reviewing permit applications and technical deficiencies for more than 20,000 hours, responding to 29,000 comments, and ensuring Sunoco addressed deficiencies identified in its initial applications.”

McDonnell added that the review included input and feedback from DEP biologists, wetland ecologists, engineers, legal staff, and permit reviewers, along with revisions to the original permit applications submitted by Sunoco. The final approvals include conditions in both the Chp. 102 and Chp 105 permits to establish environmental protections specific to this project.

The DEP did not hold an extra public comment period or hearings because the revisions Sunoco made to the applications did not drastically change right-of-ways nor the corridor of the permits.
