Sunoco Pipeline Information

News

Sunoco Pipeline, an Energy Transfer Partnership, as part of their Mariner East Pipeline Project, has reported that notification has been made to the Pipeline and Hazardous Materials Safety Administration (PHMSA) on or about June 22, 2018, that they intend to use an existing pipeline to transport Natural Gas Liquids (NGLs).                                  

Sunoco advised that it completed a refurbishing of this line in 2016 and the pipe is currently active and being used by Sunoco Pipeline to transport other petroleum products. Sunoco is required to provide PHSMA a 60-day notice that they intend to start transporting NGLs in the existing pipeline. It is expected that there will be little to no above ground activity and or construction involved in the changeover.

The changeover is currently expected to occur by the end of September.  Sunoco has provided the Pennsylvania Utility Commission (PUC) and PA Department of Environmental Protection (PA DEP) courtesy notification of this change over.

Mariner East 1 

The Mariner East 1 project involved repurposing an existing pipeline that previously carried products from the former oil refinery located at Marcus Hook in Delaware County, PA to markets in the west. The pipeline was refurbished, as the Mariner East Project, to carry 70,000 barrels daily of natural gas liquids (liquid propane and ethane) from Western Pennsylvania to Marcus Hook for both domestic distribution and export. Mariner East 1 utilizes mostly existing 8-inch diameter steel pipeline, except for a portion of the line, located in western Pennsylvania that was increased to 12-inch diameter steel pipe. The Mariner East 1 project was completed in late 2014 and is shipping both ethane and propane.

Mariner East 2 

Sunoco Logistics is proposing to expand the existing Mariner East pipeline system through the construction of the Mariner East 2 (PA Pipeline Project) project.  When constructed, this project will transport natural gas liquids from Ohio and the Pittsburgh area to the Marcus Hook facility for both domestic distribution and export. The Mariner East 2 pipeline, proposes approximately 350 miles of pipe, spanning Pennsylvania, West Virginia and Ohio.  Mariner East 2 will have an initial capacity of approximately 275,000 barrels a day of natural gas liquids using a 20" diameter pipeline.  The length of the project through Chester County is approximately 23.6 miles and in Delaware County, 11.4 miles.  Approximately 80% of the Mariner East 2/PA Pipeline Project is to be located within existing right-of-ways.

On February 13, 2017, the PA DEP issued the necessary Chapter 105 (Water Obstruction and Encroachment) permits for each county the project will cross and the Chapter 102 (Erosion and Sediment Control) permits for each PA DEP region the project will cross.  Sunoco anticipates that construction of the project will begin in late winter/early spring 2017 and that it will be completed by the end of the third quarter of 2017. Sunoco has also  determined that, in addition to the 20" ME2 pipeline, a second 16" pipeline  will be added to the Mariner East project easement.  Sunoco anticipates  that this pipeline project will be completed in mid- to late 2018.

With  the commencement of construction, Sunoco has provided DEP with a 24 hotline  number for the Pennsylvania Pipeline Project, also known as Mariner East II  (ME2).  This number is: 1(855)-430-4491.  This hotline allows for  inquiries and concerns to be directed to Sunoco during construction.  If  there are concerns related to erosion and sedimentation and site restoration,  residents can contact the Chester County Conservation District (CCCD) at (610) 925-4920.   If there are questions or concerns regarding stream or wetland crossings,  residents can call DEP directly at (484) 250-5900.
