This page was last updated on April 14, 2020

Sunoco Partners Marketing & Terminals, L.P. (SPMT) in Marcus Hook is a storage, purification, and distribution facility of natural gas liquids.

The Marcus Hook facility was a petroleum refining plant previously owned and operated by Sunoco Inc (R&M). The plant terminated its operations in 2011 and SPMT acquired the idled Marcus Hook refinery in early 2013. The site was redeveloped into a hub for natural gas liquids (NGLs) on the US East Coast. Ethane, propane, and butane make up these various NGLs, which are received via pipeline from the Marcellus Shale region and are stored, processed, and distributed to local, regional, and international markets.

Permit/Plan Approval Specifics

The SPMT facility is currently permitted under several Plan Approvals and a Title V Operating Permit (TVOP). A plan approval is required for the construction, shakedown, and/or performance testing of most projects that take place at this facility, while an operating permit is required for the continued operation of the air emission sources.

The TVOP consolidates applicable regulations and plan approvals into one document. It does not adopt any new regulations.

The unincorporated Plan Approvals include:

  • 23-0119D (continuing/completing the installation of several refrigerated storage tanks, a cooling tower, necessary piping, one new cold flare and one modified cold flare); and
  • 23-0119E (currently under the Environmental Hearing Board’s EHB’s ruling for DEP to revisit and aggregate with all associated projects as they pertain to Prevention of Significant Deterioration (PSD) and/or New Source Review (NSR) regulations).

On October 7, 2019, DEP issued a TVOP that:

The following applications are still under review by DEP:

  • Plan Approval Number 23-0119E which addresses the EHB’s Adjudication (July 29, 2019). DEP received a complete Plan Approval application package for revised Plan Approval No. 23-0119E from SPMT. The revised application was submitted as required by the EHB to reevaluate the sources and equipment permitted or authorized under Plan Approval Nos. 23-0119 through 23-0119E, Requests for Determination of Changes of Minor Significance and Exemption from Plan Approval/Operating Permit (RFDs), and future projects related to the NGLs processing, storage, and distribution operations at the facility. The reevaluation was conducted as a single aggregated project to determine the applicability of PSD and NSR requirements.
  • Plan Approval Number 23-0119J (July 29, 2019). This application is similar to, and replaces the previously submitted project under Plan Approval Number 23-0119I. Plan Approval No. 23-0119J. DEP received a complete Plan Approval application package for Plan Approval No. 23-0119J (“Project Phoenix”) from SPMT. The proposed project includes the installation of:
    • Two new 600,000-bbl refrigerated ethane storage tanks;
    • One new amine treatment system;
    • One new dehydration train system;
    • Two new refrigeration systems;
    • Two new demethanizers;
    • Two new wet surface air cooling (WSAC) systems;
    • One new elevated, air-assisted Cold Flare; and
    • Various piping connections and components.
