Act 2 Documents

*NOTE: None of the reports listed below are currently open for public comment.  However, general comments may be submitted through the Comment Submission Form tab of this website (or email or USPS as noted on the page).

Since 2003, Sunoco or Evergreen have performed site characterization activities across the entire facility, which was divided into 11 Areas of Interest (AOIs) in accordance with the 2003 Consent Order and Agreement.  Each one of the AOIs has had one or more technical reports submitted to the PADEP and EPA providing all of the environmental data collected at the property.  Historically, Belmont Terminal was included in AOI-1, but is now its own Site and is listed separately below for the purposes of reporting.

In October 2006, Sunoco submitted a notice of intent to remediate (NIR) to the PADEP entering the property into the Act 2 program. This NIR was later updated in 2014 and 2016 and a separate NIR submitted for Belmont Terminal.  NIR documents are available in the drop-down menu below. In November 2011, the facility was formally entered into the PA One Cleanup Program with the USEPA – Region III and PADEP. In November 2011, Sunoco submitted a Work Plan for Site Wide Approach under the One Cleanup Program.  Characterization and remediation work at the PES Complex is currently being performed under the September 2012 Buyer-Seller Agreement signed by Sunoco, PES, and the PADEP. The First Amendment to Consent Order and Agreement was signed in June 2020 to amend the Buyer-Seller Agreement after purchase of the site by Hilco.

Below are the Act 2 reports which have been submitted to the PADEP and USEPA to date. The most recent Remedial Investigation Report (RIR) for each AOI incorporates past data and supersedes previous investigation reports. Due to electronic file size, some reports were broken into two parts (Part 1 and Part 2) for ease of download.  Some reports below include the refinery property as a whole (not broken up by AOI) and are listed in the Refinery-Wide Reports.  In the future, some reports may also be submitted by development phase/area as defined by Hilco Redevelopment Partners since the property is being developed on an area by area phased basis.

Future Act 2 reports will also be posted on this website along with regulatory correspondence for these reports. Future reports may include but are not limited to Cleanup Plan(s) and Final Report(s).

Although the reports provided on this website include all Act 2 reports which have been submitted to PADEP and USEPA and the formal comments provided by the agencies on those reports, we have refrained from uploading all communications to the website which have been exchanged over the past several decades related to the complex. Because the investigatory and remedial approach has evolved and questions or matters which may have been raised in older communications have been addressed in more recent reports and/or otherwise rendered moot, we have refrained from posting all prior communications so as not to water down the more relevant substantive reports. The PADEP records included on this website reflect PADEP’s decision-making at various points in the overall Act 2 process but do not include an exhaustive list of every “record” in the official public file. To examine PADEP’s public file, please schedule an informal file review through PADEP’s Norristown office.

In light of the complexity and technical nature of the Remedial Investigation Reports below, Plain Language Summaries have been prepared to aid in the public’s review of these documents. One document was prepared for each AOI in 2020 and are available in the drop-down lists below.  A document titled Overview of Former Sunoco Philadelphia Environmental Investigations was also prepared in 2020 as a guide for reviewing those reports and provides some basic background information, explanation of the regulations that apply to Evergreen’s work, and some basic technical concepts that are discussed in the RIR summaries. To view the documents, click the appropriate title below. Also provided below is a list of common Acronyms found in the reports.  Note that any Act 2 report submitted after 2020 will also have it’s own Plain Language Summary that is part of the report submittal.
