Overview of Mariner East Project

mapMariner East 1 (completed)

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. For additional information on the PaDEP permits, view the DEP permit information near the bottom of this page. Construction began in late winter/early spring 2017 and the Mariner East 2 pipeline was put into service at the end of 2018. The second 16" pipeline, known as the ME2X, is being added to the Mariner East project easement. As of mid-2019, the Mariner East 2X line was still under construction.

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: 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.

Mariner East Mapping

Sunoco Mariner East 2 Municipal Maps

Sunoco Logistics has distributed a series of maps for the effected municipalities in Chester County that have the Mariner East 2 line proposed to run through them.  These maps show the proposed route of the pipeline, the type of method that is proposed for installation (either horizontal directional drilling (HDD) or open cut method), the areas where the HDD will be staged, as well as the existing Mariner East 1 Pipeline.  You can view the maps here:

* The installation of proposed ME2 pipelines in West Whiteland Township, from Shoen Road to Lincoln Highway, were originally proposed to be installed via Horizontal Directional Drilling (HDD). Open trench construction method is now being considered with the exception of roadway crossings and other environmentally sensitive areas where the pipelines will be bored.

    Joint Motion of PUC on Administrative Judges Initial Finding

    On October 2, 2014, there was a Joint Motion of the PUC (Vice-Chairman Coleman and Commissioner Witmer) to dismiss all preliminary objections, reverse the Initial Decision, and return Sunoco's amended petitions to the Office of Administrative Law Judge for further proceedings. The Commissioners indicate that this proceeding asks the PUC to decide a very specific question - "whether enclosures (walls and a roof) that are built around and over a valve control or pump station should be exempt from municipal zoning regulation." Additionally, the Joint Motion indicates that based on various mergers dating back to the 1930s, Sunoco is both a "public utility" and a "public utility corporation." Read Joint Motion

    PA Administrative Judges Initial Finding

    On July 23, 2014, Pennsylvania PUC Administrative Judges issued an Initial Finding regarding the Mariner East project. Sunoco had previously filed petitions requesting the PUC to find that control valve stations and pump stations along their proposed pipeline were reasonably necessary for the convenience or welfare of the public. Approving this request would exempt the operator from local zoning ordinances, as the facilities would be considered public utility buildings. In this application to the PUC, Sunoco was not seeking a certificate of public convenience; authorization to build the Mariner East line; approval for siting or routing of the pipeline; or compliance with environmental or public safety requirements. The Administrative Judges' Initial Finding dismissed the petitions because the pipeline operator's proposed service is not a public utility services as defined by the Pennsylvania Municipalities Planning Code (MPC) as well as the Pennsylvania Business Corporation Law.
