Evergreen is in the process of finishing the investigation activities at the former Philadelphia Refinery to identify the extent of the chemicals in soil and groundwater, in order to ultimately develop remediation (cleanup) plans for the site. During this process, Evergreen will develop reports and hold public meetings, both of which will have public notices. Throughout the process, we will post information to the... read more
In addition to the toxins already mentioned, what is the plan to deal with the benzene that is in the soil?
Posted by Tiffani Doerr & filed under .
In general, benzene and other volatile compounds are not identified for further evaluation in soils (meaning they were not detected above the statewide health standards in many locations). However, all remedial options, which can include engineering and intuitional controls will be detailed in future Cleanup... read more
These are very informative graphics (referring to the August 27th Public Information Session). What about removal of contaminants that are in the soil? Lead cannot be pumped out. All the soil must be removed.

Contamination in soil can be dealt with in many ways. Some areas of soil impact have been excavated previously. Soil remediation can also include institutional and engineering controls which eliminate a risk by blocking a pathway of exposure. Remedial plans for all media will be detailed in the Cleanup... read more
Hilco has indicated in the Soil Management Report it filed with the City that the site-specific standard for lead required for the HRP intended uses for the site is 1,000 PPM. Will Evergreen remediate to this 1,000 PPM standard rather than the 2,240 PPM previously approved by PADEP?
Posted by Tiffani Doerr & filed under .
Evergreen’s future cleanup plans will still compare all new soil data to both the statewide health and site-specific values to determine appropriate remedy selection. In addition, Evergreen will reevaluate the current site-specific standard based on DEP’s proposed new soil standards and associated input... read more
These graphics (Evergreen note: assumption is reference to graphics from the August 27th Public Information Session relating to remediation) all show problems relating to gasses and water…not contaminated soil. Will soil be removed and replaced with clean soil?
Posted by Tiffani Doerr & filed under .
The remediation systems operated at the site historically and currently were installed to address groundwater or vapors since those represented potential risk pathways, which is why they were shown during the August 27th Public Information Session. The purpose of the information session was to review historic reports which include mostly Remedial Investigation Reports. Remedial plans for all media, including soil,... read more
What other companies are involved in the cleanup, besides Evergreen?
Posted by Tiffani Doerr & filed under .
Evergreen is responsible to cleanup legacy contamination, generated prior to September 2012. Hilco Redevelopment Partners (HRP) is responsible to cleanup recent contamination, generated after September... read more
Is there a permit for the discharge of water from the wastewater treatment system to the PWD, who is the permit holder, and have the permit requirements been met?
Posted by Tiffani Doerr & filed under .
Evergreen has a permit for discharge from a remediation system directly to the PWD and is not the permittee for the onsite wastewater treatment... read more
What specific steps are being taken to clean the water from potential contaminants?
Posted by Tiffani Doerr & filed under .
Since the original Consent Order & Agreement between Sunoco and DEP in 1993, Sunoco and Evergreen have implemented several interim remedial actions at the refinery. Various remediation systems were installed in the facility in 1995 to prevent the migration of impacted groundwater offsite. Additional remediation systems have been installed since that time to either address source removal (removing petroleum... read more
Have you considered remediating with bacteria? Or mycelium? We understand they’re both more affordable options.
Posted by Tiffani Doerr & filed under .
Evergreen has considered and will continue to consider various remedial options at each area of proposed remediation. Remedial options must consider a number of factors, including but not limited to logistics, utilities, subsurface flow conditions, chemistry, nature and extent of the contamination, nutrient availability, etc. Bioremediation technologies, not specifically mycoremediation, have been/are utilized in... read more
What is the quality of the water discharged from the Pollock St well system into the Schuylkill?
Posted by Tiffani Doerr & filed under .
Groundwater collected from the Pollack St well system is not discharged directly to the Schuylkill River. Groundwater discharged from any remediation system is either processed through the facility’s wastewater treatment plant which operates under a National Pollutant Discharge Elimination System (NPDES) permit held by PES or discharged to the Philadelphia Water Department (PWD) sewer system via a Groundwater... read more
