What is being done to prevent contaminated groundwater from entering the Pollock and 26th St Sewers?

Groundwater/light non-aqueous phase liquid (LNAPL) are being recovered via remediation system recovery wells along the property boundary in an area along 26th Street. Groundwater and LNAPL are also recovered via horizontal recovery wells along the Pollack Street sewer through the facility. Sewer conditions are to be evaluated as part of the future modeling... read more

What sea level rise, if any, was the tide gate built to accommodate?

Tide gates are a common flood prevention structure for areas in a tidal zone. Tide gates close during incoming tides to prevent inundation from downstream water propagating inland, and they open during outgoing tides to drain upland areas. The tide gates at the Site were not specifically designed to address sea level rise; however, the Site will continue to be regulated under the stormwater management requirements... read more

Will Evergreen be incorporating climate resilience into its groundwater modeling?

A literature review of available, published resources on climate change for the Philadelphia region and discussion of the potential implications to Evergreen’s groundwater model will be included in the upcoming Fate and Transport RIR.  Evergreen’s groundwater flow model for the former Philadelphia Refinery has been calibrated and validated to recent environmental conditions and measured observations. As a part... read more

What is the status of your groundwater and aquifer modeling for all pollutants?

The groundwater flow model has been completed but cannot be finalized and submitted until all Remedial Investigation Reports are approved as data collected for these reports are used as the basis for the groundwater flow model. Groundwater contaminant fate and transport model efforts will be conducted subsequent to approval of the Remedial Investigation Reports since the fate and transport modeling is dependent upon... read more

There is a benzene pool that extends toward residential neighborhoods of South Philadelphia. In June 2019, PES reported fence line measurements of benzene above regulatory limits. What’s the situation? What corrective actions have been taken?

Dissolved benzene in groundwater (otherwise known as a benzene groundwater plume) is present at the former Philadelphia Refinery. The Remedial Investigation Reports summarize the benzene in groundwater that Evergreen has characterized as part of the Act 2 investigations. For example, the AOI 1 RIR presents details concerning benzene in groundwater along the eastern boundary of the former Philadelphia Refinery. These... read more

When will the revised RIRs for AOIs 4, 9 and 11 be submitted?

The Remedial Investigation Addendums for AOI 4 and 9 will be submitted once the public comment period for the approved Remedial Investigation Reports is completed and a summary document is submitted and approved by the PADEP. The investigation of the deep groundwater unit (AOI 11) has been incorporated into the other Remedial Investigation Reports since 2013 based on discussions with the PADEP, so we will not submit... read more

Does Evergreen consider the 11/7 “event” a formal meeting, and if so, does this start the timeline for them? If it does not, when will the next meeting be held?

Evergreen was disappointed that entrances were blocked at the planned meeting on Nov. 7, 2019, preventing members of the community and agency officials from engaging in a discussion about the environmental condition of the refinery property. Evergreen views the public engagement process for the site as ongoing, as comments and questions from the public have been collected since the attempted meeting which involve... read more

Public Participation that begins after the all the information is gathered, everything decided and recommendations are ready to be presented to the public is not adequate public participation. Public participation must begin at the beginning, not the end or near the end.

Sunoco submitted a public notice at the time of the Notice of Intent to Remediate (NIR) that started the Act 2 process, and similarly when the NIR was updated two times afterwards. In addition, Sunoco/Evergreen completed public notice when each of the 21 Act 2 reports were submitted to the PADEP. Evergreen also held a public meeting in 2006, during the early stages of the Act 2 activities at the Site, and remains... read more

Why did it take 10+ years, and an almost-catastrophic explosion, for Evergreen to come back and engage the public? Why was Evergreen so delinquent in doing the outreach associated with the legal/contracted obligations to this site? Until the massive explosion, the community at large had not heard from them in years and their outreach/engagement was pitiful.

The June 2019 fire at the PES facility does not relate to Evergreen’s Act 2 submittals or public involvement plan.  Since Atlantic/Sunoco purchased the refinery, there have been 21 Act 2 reports submitted and, at the time of each submission (as well as at the time of each of three Notices of Intent to Remediate (NIR) submitted for the property), a letter was sent to the City of Philadelphia and notices appeared... read more
