Potential dust from Site soils will be addressed through the remedies selected for the Site, which will be proposed in the Cleanup Plan. Measures to prevent dust generation during redevelopment should be included in Hilco Redevelopment Partner’s site development... read more
Will you commit to cleaning up all areas near residential off site areas to residential health based standards? For the part of the property that will be a public park, do residential standards apply to these areas?
Per the 2020 First Amendment to the Consent Order & Agreement dated June 26, 2020 (and the deeds transferring the parcels), Philadelphia Energy Solutions/Hilco committed to continuing to use the former refinery property for non-residential use. As such, Sunoco agreed to remediate the site to non-residential use standards under Pennsylvania Act 2 and Evergreen’s future Cleanup Plans will be developed based on... read more
Question from TASC Public Meeting: What was the impact of the recent hurricane on the ongoing remediation processes? [Evergreen note: the TASC Meeting took place in October 2020] Were any of the water treatment processes overwhelmed and were there any discharges into the River?
Evergreen has not observed any impact by heavy storm on our remediation processes at the site. Evergreen is unaware of conditions with facility wastewater treatment plants or discharges, as those are facility... read more
To what extent will you be using bioremediation technology?
Evergreen is currently using a form of biotechnology at the site for interim remedial activities. We have two biofilters on site, which take the vapors pulled out of the sewers and treat them through those filters. Bioremediation technology is not currently used to treat any groundwater. Most systems onsite currently are in place to prevent migration of contaminants to receptors such as sewers or property... read more
Remove all of the lead, we deserve a space that is safe to work and play in.
Act 2 includes procedures to allow for the reuse and development of a site while maintaining safety of the community, environment, and workers on site. This is inherently the purpose of Act 2. Evergreen will evaluate how best to do this through remediation, pathway elimination, modeling, risk assessment, and engineering and institutional controls to make sure that the workers and people of the community are safe,... read more
Conventional land remediation consists of capping the contaminated soil with tarp and/or concrete; or hauling the soil someplace else. Capping ignores the problem for a few decades at most, until chemicals leach out. In this case, into the Delaware River. Hauling the soil elsewhere just pushes the problem of leaching onto another bioregion. Neither of these methods is true remediation since we’re either burning, burying, or relocating the contamination. Eco-remediation is the most cost effective method of remediating soil and water, per figure 98 in “Mycelium Running, Paul Stamets.
Evaluation of current and potential remedial options is ongoing. Cleanup Plans will be submitted upon completion of all Remedial Investigation activities, which will consist of identification and evaluation of remedial alternatives, selection of proposed remedies, and plans for the development, construction, and initial operation of the proposed remedy and/or documentation of interim remedial actions already in... read more
Did you say that Evergreen will cleanup as Hilco redevelops/builds?
Partially. Evergreen has been remediating the site for years and remediation is ongoing. Therefore, Evergreen will have some remedial measures in place before Hilco redevelops an area of the Site, and some remedial measures are part of the development (for example capping and vapor mitigation measures in a building, if warranted). The timing of the Cleanup Plans will be based on the redevelopment schedule so... read more
We are still waiting on a city response to our request for a public hearing on Evergreen’s existing remediation infrastructure, including vents that emit fumes coming from underground pollutants.
It is our understanding that Philadelphia Air Management Services (AMS) will hold a public hearing on the draft Natural Minor Operations Permit; however, Evergreen is not aware of the timing. Questions regarding the permit application and timing of future public hearings should be directed to Philadelphia... read more
Evergreen has described petrochemical recovery results. But information has not been provided about how contamination conditions have changed over time or what the current situation is. Hilco plans to replace the existing systems, but no information has been provided as to what or why such replacement is appropriate.
Remediation systems are reviewed in the Remedial Investigation Reports. The RIRs also all include a qualitative fate and transport discussion, which addresses how conditions have changed over time. It is not expected that Hilco will need to replace any of Evergreen’s remediation systems because Hilco and Evergreen are working together to limit disruption to Evergreen’s ongoing remediation during Hilco’s... read more
And for waste that is removed, please spell out which communities that waste will be dumped on, at which facilities, the type of facility, the demographics around that facility, and whether this violates Title VI of the Civil Rights Act.
Transportation, storage, and disposal (TSD) facilities are regulated by the EPA under the Resource Conservation and Recovery Act (RCRA) through which guidance on hazardous and non-hazardous waste has been developed. Wastes that may be removed from the former refinery facility could go to various different regulated TSD facilities, which will be determined at the time based on the chemical composition and physical... read more
