Documents posted here include legal filings, findings of fact, safety reports, Township news releases and public statements, and other pertinent materials for your review. We greatly appreciate your support and welcome your questions.

August 5, 2019 “Loud Boom” Incident

On Monday, August 5th, shortly after 8:00 PM, West Goshen Police responded to several 911 calls regarding a loud “boom” in the area of  Sunoco Pump Station close to Route 202 and Boot Road.

It was determined to be a noise associated with the station itself and Sunoco released the following statement regarding the event:
“During routine maintenance at our Boot Station in West Goshen Twp., there was a backfire on a flare at approximately 8 pm as the station was brought back online. This resulted in a loud noise, similar to a car backfiring. We apologize for any inconvenience this may have caused.”

Chester County Department of Emergency Services was notified shortly after the noise and determined it was not an emergency situation.

The PA Public Utilities Commission is aware of the incident as well.

Additionally, the Township is formally investigating the matter to determine what happened, why, and how such an event can be handled in the future. Although the only first responders at the Township-level are West Goshen Police, we will do everything in our power to find out as much information as we possibly can on behalf of our residents.

2018 Pipeline Training Presentation / PHMSA Training Manual

In 2018, Rep. Carolyn Comitta obtained a $134,000 job training grant for West Goshen Township to facilitate first responder pipeline firefighter training and Highly Volatile Liquids (HVL) training for municipal staff members.  25 firefighters from the West Chester Fire Company and the Chester County HAZMAT team attended five full days of hands-on firefighter training at the Texas A&M University (TEEX) “Disaster City” school in College Station, Texas in September 2018.  23 staff members from Chester County municipalities along the Mariner I route took a three day training session on HVL’s at the United States Department of Transportation’s Transportation Safety Institute, hosted by PHMSA.  Many thanks to Rep. Comitta and her staff for obtaining this important job and safety training grant.

Casey LaLonde, West Goshen Township Manager, provided a presentation to the West Goshen Township Board of Supervisors and the public at the May 30, 2019 Board of Supervisors meeting.  His presentation may be found below, as well as the Transportation Safety Institute training manual.


Report of “loss of circulation” at Boot Road HDD construction site

It was reported to the Township that on April 15, 2019, Michels, the company hired by Sunoco / Energy Transfer Partners to install the Mariner II & IIx pipelines, experienced a “loss of circulation,” meaning an amount of bentonite clay drilling fluid escaped into a void underground.  This is different from an “inadvertent return,” in which bentonite clay drilling fluid escapes the drilling hole and is spilled on the ground.  Residents with on-lot well water were notified of the “loss of circulation” by certified mail from Sunoco / Energy Transfer.  If you received a letter and experience any changes to your on-lot well water, please follow the instructions contained in the letter.  This “loss of circulation” has no affect on those with public water supplied by Aqua, PA.

Sunoco Logistics (aka Energy Transfer) to utilize existing 12″ line for Mariner II

Sunoco Logistics announced in early July 2018 that it would be utilizing an existing 12″ line for in lieu of their long-delayed Mariner II line.  The Mariner II and IIx construction has been halted in various Chester County municipalities due to issues with their Horizontal Direction Drilling (HDD) program.  The repurposed 12″ line runs almost parallel to the existing 8″ line that Sunoco Logistics has utilized since 2015 to pump Marcellus Shale Highly Volatile Liquids (HVL’s) to Marcus Hook for processing.  Sunoco Logistics applied to PHMSA in early July for permission to repurpose the line to carry HVL’s instead of the gasoline products currently being shipped west.  West Goshen Township’s safety expert, Richard Kuprewicz, will review the pipeline integrity management plan as provided by Sunoco Logistics and report back to the West Goshen Township Board of Supervisors with his review.

Documents / Litigation

FAQs – Frequently Asked Questions

Why did West Goshen Township sue Sunoco Logistics?

West Goshen Township filed a lawsuit against Sunoco Logistics in March, 2017 after it was discovered that Sunoco Logistics was not abiding by the May, 2015 Settlement Agreement, namely that Sunoco Logistics, without the required notice to West Goshen Township, moved the automatic valve locations for the Mariner II pipelines.

Why did Sunoco Logistics breach the Settlement Agreement if it agreed to it in the first place?

The Township has yet to determine why Sunooco Logistics has breached the Settlement Agreement, but the current litigation aims to determine why the breach occurred and find a remedy.

What is the economic impact of the Mariner II pipelines on West Goshen Township?

First, the project scuttled an approximately $35,000,000 approved land development project, namely Traditions Independent Living, at the unauthorized location of the Mariner II valve stations on the eastern side of Boot Road at Rt. 202.  The Traditions development project would have provided approximately $400,000 in road improvements to the congested intersection of Rt. 202 / Boot Road / Greenhill Road.  In addition, the project would have provided over $100,000 in building permit fees and significant earned income and real estate taxes to the Township.  The Traditions project would have provided a nearby independent living facility accessible to retired Township residents.

Second, building a 10,000 square foot valve station on the eastern side of Rt. 202 at Boot Road effectively stops any economic development or land development of the remaining parcel, given that the proposed valve station is situated in the middle of the parcel.  This parcel will become tax-exempt, given the Pennsylvania Public Utility Commission and many Pennsylvania Commonwealth Court rulings that Sunoco Logistics is a tax-exempt public utility.

What’s it costing West Goshen Township to fight Sunoco Logistics?

As of July 2018 and since early 2014, West Goshen Township has expended over $705,000 in legal fees fighting Sunoco Logistics.  These legal fees are in addition to the countless Township staff hours devoted to this issue.

May West Goshen Township recover its legal fees for this fight?

West Goshen Township may seek recovery of legal fees for this prolonged fight, but the Public Utility Commission would have to approve recovery of legal fees.

What’s the Mariner I & II project worth to Sunoco Logistics?

The project installation costs just for the two Mariner II pipeline projects is estimated at $3,500,000,000.  Profits for Sunoco Logistics after project completion are unknown.

How much will Sunoco Logistics be paying to the West Goshen Township to run the two new pipelines through the Township?


How long will this litigation go on?

The current litigation should be complete by September 2018.

Why didn’t West Goshen Township just tell Sunoco Logistics it did not want any new pipelines installed in the Township?

After Sunoco Logistics applied for and received Public Utility status, the Township no longer had any jurisdiction over the installation of the pipelines. The Township enacted an Ordinance in 2014 that prohibited the installation of private pipelines in residential areas, but following Sunoco Logistics’ approval as a Public Utility by the Pennsylvania Public Utility Commission, the Township’s jurisdiction over pipelines was removed.
