Pipeline Construction Update

Construction Methods

Energy Transfer (which bought Sunoco) continues to construct the Mariner East 2 and 2X pipelines in West Whiteland Township through their contractor, Michels. Construction is not expected to be completed until some time in 2020. 

Where you see large sound walls around pipeline construction sites, Energy Transfer is installing pipes deep underground via horizontal directional drilling (HDD). 

Where HDD does not work because of geology or other factors, Energy Transfer is opening trenches and installing the pipe where they can and boring underneath other areas, such as roads and streams, where they cannot. 

Mariner East 2 and 2X Construction Update

(updated October 9, 2019)

Shoen Road north to Devon Road in Uwchlan Township 

Construction method: HDD; drill site at Whiteland West Apartments 

Status: Commonwealth Court and the PUC recently lifted the stay on construction of the 16” pipeline that was imposed in 2018. Sunoco is expected to resume drilling at the Shoen Road drill site on or around October 10th, and at the Devon Road drill site on or around October 14th.

Shoen Road south to Coeway Lane  

Construction method:  open trench, except for boring under the stream and Route 100 

Status: Both pipes have been installed from Shoen Road to the stream; boring under the stream and Route 100 is on hold pending a decision on issuance of a modified Department of Environmental Protection (DEP) permit to change the type of bore.   

Coeway Lane to Swedesford Road 

Construction method:  open trench, except for boring under Exton Lane and Swedesford Road  

Status: Open trench work for both pipes is complete.  Installation of the pipelines under Swedesford Road is almost complete.  In the next couple weeks, final landscape restoration will be done along Exton Lane.

Swedesford Road to Laborers 

Construction method: open trench, except for bores under wetlands, woods and Lincoln Highway 

Status: Open trench construction through Meadowbrook Manor Park is complete; open trench work by the library is on hold due to litigation, and boring under environmentally sensitive areas and Lincoln Highway is on hold pending a decision on issuance of a modified DEP permit to change the type of bore.

Laborers to Exton Station/Stonegate Court 

Construction method:  HDD for the 16”; under review for the 20” 

Status: The 16” pipe was installed via HDD and led to the subsidence by Lisa Drive. Energy Transfer has applied for a major modification of their DEP permit to allow for open trench construction for the 20” pipe, except for under the railroad and 30 bypass where they would bore.   

Stonegate Court to Pullman Drive 

Construction method: HDD; drill site on Stonegate Court 

Status: HDD is underway.

Pullman Drive to Ship/Boot Road (Corner Park Apartments)  

Construction method: HDD; drill site by Corner Park Apartments  

Status: The hole for the 16” pipe was drilled in 2018. The hole is being reamed again and pull back is expected to happen in October.

Ship/Boot Road to 202 drill site in West Goshen Township

Construction method: HDD; drill site at Corner Park Apartments  

Status: 16” pipeline installed.  Drilling for the 20” pipeline may start later this fall from the drill site near Goshen Fire Company.
