8/16/18 – DEP Completes Review, Accepts Permit Modification Requests for Mariner East 2 in Chester County

Norristown, PA – The Pennsylvania Department of Environmental Protection (DEP) announced today it has completed its review of requests for modifications to Chapter 102 (Erosion and Sediment Control) and Chapter 105 (Water Obstructions and Encroachments) permits submitted by Sunoco Pipeline, LP (SPLP) for parts of the Mariner East 2 pipeline. The requests are for two sites in West Whiteland Township, Chester County.

SPLP’s proposed modifications are a result of its re-evaluation of the original plan to conduct Horizontal Directional Drilling (HDD). SPLP has proposed to change methodology from HDD to conventional bore for one drill site, and from HDD to a combination of conventional bore, open trench and HDD for the other drill. As a result of the changed methodology, potential impacts to a public water supply well, other water resources and sensitive areas are expected to be avoided.

“These approvals have undergone substantial and thorough reviews by technical staff, with careful consideration given to the significant public input received during the extended comment period and public hearing held this past spring,” said DEP Secretary Patrick McDonnell.

More detailed information regarding these modifications, including the amended permits and comment response document, can be found on DEP’s Mariner East 2 webpage on its Pipeline Portal.

At their meeting on July 17,  2018 the Board of Supervisors adopted Resolution 2018-78 authorizing the creation of a Pipeline Task Force. The Mission Statement for the Task Force reads as follows:

“The Pipeline Task Force shall advise the Board of Supervisors on pipeline infrastructure matters affecting or impacting East Goshen Township and its residents.”

If you are interested in serving on the Task Force, please complete the ABC Volunteer form and submit it with a copy of your resume to Rick Smith, Township Manager.


  • Sunoco intends to start the open cut pipe installation in front of Giant Supermarket on Boot Road in the near future.
  • Sunoco is in the process of reevaluating all of the Horizontal Direction Drills (HDDs). Sunoco does not know how long this will take.
  • In June Sunoco advised Pipeline and Hazardous Materials Safety Administration (PHSMA) that they intend to use the existing 12” line to transport Natural Gas Liquids (NGLs).  This line is currently used to transport other petroleum products. They need to give PHSMA a 60 day notice so they intend start transporting NGLs in mid to late August. This will reduce the pressure to complete the Mariner East 2 and Mariner East 2X pipelines.


On Thursday, June 14th, the PA Public Utility Commission partially upheld and partially reversed the Administrative Law Judge’s May 24, 2018 interim emergency order regarding West Whiteland Township. A copy of the decision can be found here.

On May 24, an Administrative Law Judge of the Public Utility Commission ruled in favor of Senator Dinniman’s request for emergency relief, shutting down the operation of Mariner East 1 and halting construction on Mariner East 2 & 2X.

In her decision, Judge Elizabeth Barnes wrote, “”I find there to be an imminent risk to the public and a need for immediate relief and further study to be done on ME1, ME2 and ME2X for the Commission and its Bureau of Safety Engineers to evaluate before construction should resume on ME 2 or ME2X in West Whiteland Twp. and before a potential catastrophic event occurs on ME 1. Additionally, local and state government needs time to create emergency evacuation and notification plans and to educate the public before operations should resume.”

Sunoco Pipeline LP now has 30 days to conduct geophysical and geotechnical studies to the PUC.
