Groundwater Remediation Status Report, First Half 2020

Dear Mr. Brown: This semi-annual report summarizes Operation & Maintenance (O&M) work completed at the Philadelphia Energy Solutions Refining & Marketing LLC (PES) Philadelphia Refining Complex (Complex) and the Sunoco Partners Marketing and Terminals L.P. (SPMT) Belmont Terminal between January 1, 2020 and June 30, 2020. Detailed information regarding O&M activity is included in the attached tables for the PES Complex and Belmont Terminal as prepared by Stantec Consulting Services Inc. (Stantec). This letter summarizes the information detailed in the tables plus additional activities under the “Work Plan for Site Wide Approach under the One Cleanup Program” (Site Wide Approach) such as investigations of the various Areas of Interest (AOIs). In compliance with the 2003 Consent Order and Agreement (CO&A) entered into between Sunoco Inc. (R&M) (Sunoco) and the Pennsylvania Department of Environmental Protection (PADEP) for the PES Complex located at 3144 Passyunk Avenue in Philadelphia, Pennsylvania, Sunoco has completed site characterization activities for all AOIs. The Complex has since entered into the Pennsylvania One Cleanup Program. On November 30, 2011, Sunoco submitted a Site Wide Approach to the PADEP and the United States Environmental Protection Agency (USEPA). The Site Wide Approach clarified the technical method beyond the CO&A and provided an anticipated schedule for future Act 2 submissions with respect to the Philadelphia Refinery remediation program. Effective December 30, 2013, Philadelphia Refinery Operations, a series of Evergreen Resources Group, LLC (Evergreen) assumed Sunoco legacy remediation liabilities with respect to the PES Complex. All remediation of Sunoco’s/Atlantic’s historic environmental liabilities at the PES Complex and Belmont Terminal will be managed moving forward by Evergreen. Environmental liabilities following the September 8, 2012 purchase and transfer of the Philadelphia Refinery to PES are managed by PES. On June 26, 2019, PES announced the closure of the refining complex. As of June 26, 2020, Hilco Redevelopment Partners (HRP) completed its purchase of the site. HRP plans to redevelop the site as an industrial park and has no plans to operate the site as a refinery. Evergreen will continue to submit the required documentation and implement remedial obligations for Evergreen’s remediation program. Supplemental characterization data obtained following an approved Area of Interest (AOI) Remedial Investigation Report (RIR) or Site Characterization Report (SCR) will be incorporated in a future Act 2 deliverable. Evergreen will submit a Groundwater Remediation Status Report with the O&M summary, figures, tables, and Act 2 submittal updates on an annual basis coinciding with the annual groundwater

gauging and monitoring. On the alternating six-month interval, Evergreen will submit an abbreviated Groundwater Remediation Status Report detailing the O&M summary with limited tables and without figures.

AOI 1 – Point Breeze Refinery No. 1 Tank Farm and No. 2 Tank Farm; and Belmont Terminal Consent Order / Characterization Status Sunoco submitted to the PADEP and the USEPA a SCR for AOI 1 dated June 30, 2005. Based on comments received by the PADEP with regard to the AOI 1 SCR, Sunoco prepared and submitted to the PADEP a revised SCR for AOI 1 dated July 17, 2006. The recommendations in the AOI 1 report were to supplement the existing remediation system along the northwestern portion of the Belmont Terminal and southeastern portion of the No. 2 Tank Farm. Sunoco has implemented these actions as detailed in previous reports. In addition, Sunoco provided the PADEP a Remedial Action Plan (RAP) for AOI 1 in January 2008. As a result of the 26th Street North Remediation System study and the S-50 Area (26th Street South) investigation, an addendum to the RAP was considered necessary. In December 2008, a RAP Addendum for AOI 1 was submitted to address the 26th Street North Remediation System data analysis and the 26th Street South investigation and subsequent remedial actions. Evergreen submitted a revised AOI 1 RIR on August 5, 2016 which was approved by the PADEP on November 1, 2016. Evergreen conducted characterization activities at the Belmont Terminal during the reporting period including a geophysics survey. The activities were conducted to aid in providing additional characterization information to be utilized as part of future modeling efforts for the Complex. Belmont Terminal Remediation System – Operation During the First Half of 2020 The Belmont Terminal Remediation System consists of two components including the Frontage Road System and the Loading Rack System. On August 30, 2012, the Frontage Road System was turned off and will remain offline unless there are significant increases in light non-aqueous phase liquid (LNAPL) in the recovery wells. The recovery wells were gauged on June 2, 2020, and no LNAPL was detected. The Loading Rack System consists of five dual-phase pumping systems (RW-4, RW-22, RW-23, RW-24, and RW-25). Each recovery well contains separate pumps controlled by density floats and conductivity probes to pump groundwater and LNAPL. Recovered groundwater is discharged to an onsite process sewer. LNAPL thicknesses are monitored, and pumps are turned on/off as needed based on recoverable LNAPL accumulations in each recovery well. The recovered LNAPL is stored in a 5,000-gallon holding tank, the contents of which are pumped out and recycled on an as needed basis. During the reporting, period the pumps in RW-4, RW-24, and RW-25 were active. The Loading Rack System was operational during the reporting period. System performance and operational status for the Loading Rack System can be found in Appendix 1. A total of 1,125,666 gallons of groundwater and 207 gallons of LNAPL was recovered by this system during the first half of 2020. Shunk Street Sewer Ventilation System and Biofilter – Operation During the First Half of 2020 The system remained operational during the reporting period. Details of the Shunk Street Sewer Ventilation System and Biofilter operational status during the first half of 2020 can be found in Appendix 1.


26th Street North Remediation System - Operation During the First Half of 2020 The 26th Street North Remediation System was modified in 2015 to increase the overall effectiveness of the system and was restarted on October 12, 2015. The four-inch diameter recovery wells (S-180, S-181, S-182, S-183, S-184, S-185, S-186, S-187, S-188, S-189, S-190, S-191, and S-192) were replaced with six-inch diameter recovery wells. Additionally, RW-400 and RW-402 are connected to the system for a total of fifteen recovery wells. Within each well, a QED Environmental Systems Model AP-4+T AutoPump was installed to recover groundwater and LNAPL. Each recovery well contains a two-inch diameter lateral discharge line that connects to a four-inch high density polyethylene (HDPE) trunk line, which transfers the total fluids to an onsite process sewer. The pumps utilize compressed air, which is supplied by a Kaeser rotary screw air compressor. A one-inch diameter air line runs to each recovery well and is reduced to a 3/8-inch diameter line in each well vault at the pneumatic pump. The 26th Street North Remediation System was operational during the reporting period. Details for the 26th Street Sewer North Remediation System performance data and operational status can be found in Appendix 1. A total of 7,982,150 gallons of total fluids was recovered by this system during the first half of 2020. 26th Street and Packer Avenue Sewers Biofilter Remediation System – Operation During the First Half of 2020 The 26th Street and Packer Avenue Sewers Biofilter System was upgraded including replacing the compost beds, repairing the duct work, and replacing or repairing the fans. The system was restarted on June 6, 2016 for final stages of startup and system startup was completed on November 10, 2016. The system was operational during the first half of 2020. Details for the 26th Street and Packer Avenue Sewer Biofilter System performance data and operational status can be found in Appendix 1.

AOI 2 – Point Breeze Refinery Consent Order / Characterization Status The AOI 2 SCR/RIR was submitted to the PADEP and the USEPA on September 29, 2010. A revised RIR was completed in July 2017. PADEP approved the report on October 18, 2017. Pollock Street West End Remediation System – Operation During the First Half of 2020 During October 2011, heavier than usual quantities of oil were observed within the Pollock Street sewer outfall. As a result, Sunoco completed the expansion of the existing vertical recovery well remediation system in the vicinity of the Pollock Street sewer outfall in February 2012. The system, referred to as the Pollock Street West End System, consists of a total of ten 4-inch diameter recovery wells on the east side of River Road and twenty 6-inch diameter recovery wells on the west side of River Road. Groundwater and LNAPL are removed from select recovery wells using pneumatic submersible pumps. All liquids are processed through an oil/water separator (OWS) and water is discharged to a refinery process sewer (S-10 Sump). LNAPL is recovered in a 550-gallon tank and then recycled by the PES Complex. A report describing the details of the investigation and remediation performed in response to the oil observed in the Pollock Street sewer outfall was submitted to the PADEP and the USEPA on June 29, 2012. The Pollock Street West End Remediation System was turned off December 19, 2016 to evaluate LNAPL recharge.

The system remained off during the first half of 2020.


Pollock Street Horizontal Well Remediation System – Operation During the First Half of 2020 The Pollock Street Horizontal Well Remediation System consists of HW-1, HW-2, and HW-3. HW-1 was installed in July 2004 along the north side of the Pollock Street sewer from approximately RW-103 to approximately 100 feet west of RW-101. HW-2 and HW-3 were installed from approximately RW-103 to the intersection of Pollock Street and 16th Street in the first quarter of 2006. Groundwater and LNAPL from HW-1 and HW-2 discharge directly into a Benzene National Emission Standard for Hazardous Air Pollutants (NESHAP) controlled sewer, whereas groundwater and LNAPL from HW-3 discharge directly into an onsite process sewer. Totalizers were installed in HW-1 and HW-2 on May 25, 2013 and July 6, 2015 respectively. The estimated flow rate for HW-3 as determined by pump testing is 15.38 gallons per minute (gpm). The Pollock Street Horizontal Well Remediation System was operational during the first half of 2020. System performance data and operational status can be found in Appendix 1. A total of 7,475,285 gallons of total fluids was recovered by the Pollock Street Horizontal Well Remediation System during the reporting period. Pollock Street Sewer Outfall – Operation During the First Half of 2020 The Pollock Street Sewer outfall is checked for product accumulations or sheening. LNAPL will be handled by Evergreen contractors with spill control equipment to minimize or prevent releases to the Schuylkill River. Evergreen has continued to maintain a skimmer system located in the tide gate area. The skimmer discharges to a refinery process sewer (S-13 Sump). The skimmer will be activated if recoverable quantities of LNAPL are observed at the tide gate area. Except for the completion of preventative maintenance and equipment testing, the outfall skimmer remained off for the first half of 2020 due to the absence of recoverable oil in the outfall.

AOI 3 – Point Breeze Refinery, Impoundment Area There are no Evergreen groundwater or LNAPL remediation systems active in this area. The AOI 3 SCR/RIR was submitted to the PADEP and the USEPA on September 27, 2010. The SCR/RIR stated that given the limited occurrence and mobility of LNAPL observed in RW-2, the former remediation system in this area will remain offline. A revised RIR for AOI 3 was submitted March 20, 2017 and approved on June 14, 2017. The disposition of remediation systems in AOI 3 will be revisited in the Site Wide Cleanup Plan. LNAPL was identified in S-414 and significant increases in LNAPL thicknesses were observed in two wells (S-283 and S-382) during the annual sitewide gauging in June 2018. PES was notified of the observations and an underground product line was determined to have released reformate from the UDEX feed line that runs from the 860 Unit in the Point Breeze Refinery to the Girard Point Refinery. PES has installed active skimming systems located at three wells, S-283, S-382, and S-429.

AOI 4 – Point Breeze Refinery, No. 4 Tank Farm Area Consent Order / Characterization Status AOI 1 and AOI 4 were identified by Sunoco as the first areas of the refinery to be investigated in accordance with the Phase II Corrective Action Schedule included in the Current Conditions Report (CCR). Sunoco submitted a SCR to the PADEP and the USEPA for AOI 4 on August 24, 2006. A repackaged SCR/RIR was submitted to the agencies on October 16, 2013. A “Disapproval of Remedial Investigation Report” was received from the PADEP on January 16, 2014. A revised RIR was submitted on March 24, 2017. The revised RIR was disapproved by the PADEP in a


letter dated June 21, 2017 due to lack of offsite wells. In 2018, five additional monitoring wells (S-374, S-375, S-376, S-377, and S-378) were installed offsite adjacent to the Penrose Avenue Remediation System. Evaluation of these wells is conducted during quarterly groundwater gauging events. A geophysics survey was conducted in February 2020 to further investigate the offsite conditions. Soil and water samples as well as additional monitoring wells are currently being installed to confirm output from the geophysical survey. A RIR Addendum will be submitted in the future to summarize available offsite information. Penrose Avenue Remediation System – Operation During the First Half of 2020 Following characterization of AOI 4, Sunoco installed a hydraulic control system on the southern border of AOI 4. This system is permitted for discharge to the Philadelphia Water Department (PWD) and by Philadelphia Air Management Services (AMS). Installation of the Penrose Avenue Remediation System was completed in December 2012. Following minor modifications to the system to facilitate water discharge monitoring in accordance with the PWD groundwater discharge permit, the system was started on March 20, 2013. LNAPL thicknesses are monitored and pumps are turned on/off as needed based on recoverable LNAPL accumulations in each recovery well. On February 21, 2018 pumps were installed in S-221, S-236, and S-237 to address LNAPL in those wells. During this reporting period, recovery wells RW-700, RW-701, RW-702, RW-703, RW-704, S-221, S-236, and S-237 were active. On March 10, the groundwater remediation system was taken out of service pending the PWD discharge permit approval. The system remained off for the rest of the reporting period. System performance data and operational status can be found in Appendix 1. A total of 703,600 gallons of groundwater and 259 gallons of LNAPL were recovered by the Penrose Avenue Remediation System during the reporting period. Additionally, the installation of an in-situ Submerged Oxygen Curtain (iSOC) was initiated during the second half of 2018. The system consists of seven oxygen injection points located in RW-706, RW-709, RW-711, RW-712, RW-713, RW-714, and RW-715 with the purpose of creating an oxygen barrier to protect offsite receptors from migrating contaminants. The iSOC system was turned off April 7, 2020 for repairs. The iSOC system will be evaluated after ongoing investigation and characterization activities. S-30 Remediation System – Operation During the First Half of 2020 The S-30 Remediation System consists of a LNAPL pump, probe assembly, and control panel. The recovered LNAPL is stored in a 2,500-gallon holding tank, the contents of which are recycled by the PES Complex on an as needed basis. The system was operational during the first half of 2020. System performance data and operational status can be found in Appendix 1. A total of 75.5 gallons of LNAPL was recovered by the S-30 Remediation System during the reporting period.

AOI 5 – Girard Point Refinery, South Tank Field Consent Order / Characterization Status In accordance with the Site Wide Approach, a SCR/RIR/Cleanup Plan was submitted to the PADEP and the USEPA on December 13, 2011. Sunoco received a RIR/Cleanup Plan disapproval letter from the PADEP on March 15, 2012. A revised RIR was submitted on January 16, 2016 and was approved by the PADEP on May 2, 2017.

AOI 6 – Girard Point Refinery, Chemicals Processing Area


Consent Order / Characterization Status AOI 6 was identified by Sunoco as the third area of the refinery to be investigated in accordance with the Phase II Corrective Action Schedule included in the CCR. A SCR for AOI 6 was submitted to the PADEP and the USEPA on September 29, 2006. A repackaged SCR/RIR was submitted to the agencies on September 3, 2013. PADEP issued a disapproval letter on November 27, 2013. A revised RIR was submitted on November 21, 2017 and was approved by the PADEP on February 26, 2018. 27 Pump House Area The remediation system that existed in the area of 27 Pump House was turned off September 20, 2010 due to absence of recoverable LNAPL. Passive remediation began on October 10, 2010 with the installation of absorbent socks in wells B-124, B-132, B-137, B-139, B-142, B-143, and B-147. Based on limited recoverable LNAPL in the proximal wells, passive remediation was discontinued on January 26, 2015 and the equipment was subsequently removed. Due to continued presence of elevated benzene concentrations in soil and groundwater in this area, remediation alternatives are being evaluated. Mobile Solar Powered LNAPL Recovery System

A solar powered LNAPL pump was operated at B-124 to evaluate the LNAPL recovery potential. A total of 9.9 gallons of LNAPL were recovered by the B-124 during the reporting period.

AOI 7 – Girard Point Refinery, Fuels Processing Area Consent Order / Characterization Status In accordance with the Site Wide Approach, a repackaged AOI 7 SCR/RIR was submitted to the PADEP and the USEPA on February 29, 2012. A RIR Addendum was submitted to the agencies on September 19, 2013. On December 18, 2013, Sunoco received comments on the RIR Addendum from the PADEP. These comments were addressed in the revised RIR that was submitted June 9, 2017. The RIR was approved in correspondence dated August 30, 2017. 3 Separator Remediation System – Operation During the First Half of 2020 On July 12, 2011, Sunoco reported a hydrocarbon sheen on the Schuylkill River to the National Response Center. The sheen was directly adjacent to the Girard Point Refinery No. 3 Separator. In response to the sheen on the river, Sunoco investigated the source of hydrocarbons to the river through the installation of monitoring wells and exploratory excavation around a process sewer junction box associated with the 137 Crude Unit and the No. 3 Separator. The monitoring wells demonstrated measurable oil on the water table and the exploratory excavation revealed integrity issues with the junction box. The junction box and associated bulkhead penetration were sealed with concrete. Construction of a ten recovery well hydraulic control system was completed on August 23, 2012 and included RW-801, RW-802, RW-803, RW-804, RW-805, RW-806, RW-807, RW-808, RW-809, and RW-810. Groundwater and LNAPL are extracted using pneumatic submersible pumps and total fluids pass through an OWS. Water is discharged to an onsite process sewer. LNAPL is recovered in a 1,100-gallon holding tank and recycled by the PES Complex. In 2013, PES assumed primary responsibility for the 3 Separator System due to newer PES releases from the sewer system, which connects the 137 Crude Unit to the No. 4 Separator, in the vicinity of the No. 3 Separator.


The 3 Separator Remediation System was operational during the first half of 2020. System operation details and performance data for the system can be found in Appendix 1. A total of 1,323,000 gallons of groundwater and 46.5 gallons of LNAPL were recovered by the 3 Separator Remediation System during the first half of 2020.

AOI 8 – Point Breeze Refinery, North Yard Consent Order / Characterization Status A SCR was submitted to the PADEP on September 30, 2008. A repackaged SCR/RIR incorporating the PADEP’s comments was submitted to the PADEP and the USEPA on January 31, 2012. Comments from the PADEP on the SCR/RIR were received by email on July 7, 2012. A revised RIR dated December 21, 2017 was submitted to the PADEP. PADEP issued an approval letter on March 22, 2018. Northern/Verizon Area Maiden Lane Remediation System The northern boundary of AOI 8 near the South District Work Center of Verizon Pennsylvania, LLC (Verizon SDWC) property was evaluated for offsite impacts and system installation. A test well (N-157) was installed in 2017 and a well performance test was conducted to evaluate the feasibility of LNAPL recovery as a remedial option near the adjacent Verizon SDWC property. During the second half of 2019, a horizontal well (HW-4) was installed in this area along the refinery property boundary for the purpose of groundwater and LNAPL recovery. A total fluids groundwater remediation system has been installed and is expected to be operational in the second half of 2020. All liquids will be processed through an OWS. Groundwater will be discharged to a PWD sewer and LNAPL will be stored in a 550-gallon tank for future recycling. PGW Border Remediation System – Operation During the First Half of 2020 The PGW Border Remediation System was replaced during the reporting period. Evergreen installed 30 new recovery wells and new remediation system equipment which allow groundwater and LNAPL recovery along the PGW border in the area of the former remediation system. The PGW Border Remediation System began operation in February 2020 and was operational during the reporting period. All liquids are processed through an OWS and water is discharged to a refinery process sewer. LNAPL is recovered in a 550-gallon tank and then recycled by the PES Complex. A total of 1,556,706 gallons of groundwater and 1,927 gallons of LNAPL were recovered by the PGW Border Remediation System during the reporting period. Jackson Street Sewer Remediation System – Operation During the First Half of 2020 The Jackson Street Sewer Remediation System consists of two components, an inactive total fluids system with submersible pumps that formerly recovered groundwater and LNAPL (Jackson Street System) and a vapor suppression water curtain installed in the Jackson Street Sewer Remediation System (Jackson Street Water Curtain). Due to limited LNAPL presence, the Jackson Street System is offline and equipment subsequently removed. The Jackson Street System will remain off unless there are significant increases in LNAPL in the proximal wells.


The Jackson Street Water Curtain was operational during the first half of 2020 and is monitored weekly. Vapor readings are collected at the water curtain and at the intercepting chamber along 26th Street. System data and operational status for the first half of 2020 is included in Appendix 1. Evergreen will continue to operate the Jackson Street Water Curtain and report performance information in semi-annual Philadelphia Refinery Groundwater Remediation Status Reports. Details regarding plans to maintain this vapor mitigation system will be included in a future Act 2 deliverable. No other vapor intrusion assessment activities are recommended for AOI 8. Sunoco agreed at a July 30, 2009 meeting to sample the air in the sewer onsite and offsite following notification from the PADEP of a neighborhood (28th and McKean Streets) complaint. No complaints regarding sewer odors were received during the first half of 2020.

AOI 9 – Schuylkill River Tank Farm

There are no groundwater or LNAPL remediation systems operational in AOI 9. A SCR was submitted to the PADEP and the USEPA on October 30, 2009. A revised RIR was submitted to the agencies in December 2015. The RIR was denied and a RIR Addendum to address the deficiencies was submitted on February 8, 2017. On April 18, 2018 the PADEP disapproved the RIR Addendum due to lack of offsite wells. Evergreen has obtained information from existing offsite wells, and five additional wells (S-146SRTF, S-147SRTF, S-148SRTF, S-149SRTF, and S-150SRTF) were installed in October 2018 along Essington Avenue, west of the Schuylkill River Tank Farm, to evaluate offsite groundwater conditions. A RIR Addendum will be submitted in the future to summarize available offsite information.

AOI 10 – Point Breeze Refinery, West Yard

There are no groundwater or LNAPL remediation systems operational in AOI 10. A SCR/RIR was submitted to the PADEP and the USEPA on June 29, 2011. Approval of the RIR was received from the PADEP on January 6, 2012. An ecological assessment was conducted in 2015 and 2016 and an Ecological Risk Assessment Report was submitted in June 2016, which was approved on November 10, 2016. A Solid Waste Management Unit (SWMU) closure letter which addressed past disposal areas located in AOI 10 and AOI 8 (SWMU 1 and SWMU 2, respectively) was submitted to the USEPA on February 16, 2016. On November 29, 2016, the USEPA issued a response letter approving no further investigation or remediation required for SWMU 2 and denying the no further action request for SWMU 1. Evergreen collected additional information in 2017 to address the USEPA letter as well as the 2016 PADEP comments on the 2011 SCR/RIR and the Ecological Risk Assessment Report. A follow-up SWMU closure letter will be submitted to address SWMU 1 along with all other SWMUs previously identified at the facility to request concurrence that no further investigation is required, and acknowledge if any SWMUs require continued long-term stewardship.

AOI 11 – Lower Aquifer

The SCR/RIR was submitted to the PADEP and the USEPA on September 12, 2011. Sunoco received comments to the report by email on December 9, 2011. A Final Report was submitted to the agencies on June 21, 2013 which included activities to address the SCR/RIR disapproval. Sunoco received a “Disapproval of Final Report” from the


PADEP dated September 26, 2013. Subsequent collection and reporting of characterization information from the lower aquifer wells across the facility has been incorporated into the other AOI RI Reports submitted to date.

Groundwater Monitoring The current monitoring program consists of groundwater and LNAPL gauging and sampling of select monitoring wells. The wells are generally selected to monitor LNAPL thicknesses and determine hydraulic effects of targeted remediation systems. Sitewide well gauging events are also conducted to identify the presence of LNAPL and determine groundwater flow patterns. Annual sitewide groundwater sampling has historically been performed in the second quarter in conjunction with annual sitewide gauging; however, this year the monitoring program was postponed pending the completion of characterization activities and change of facility ownership. The groundwater sampling schedule will be flexible depending on the fate of the facility and remediation goals. Liquid level measurements collected during the first quarter of 2020 are provided in Table 1. The second quarter 2020 liquid level measurements are provided in Table 2. Monitoring wells that were observed to demonstrate a change in LNAPL thickness is presented in Table 3. The LNAPL thicknesses in these wells will be tracked to determine if changes are due to natural conditions such as seasonal groundwater fluctuation or other factors. Please contact me at (302) 477-1305 or [email protected] with any questions or comments. Best Regards, Evergreen Resources Management Operations Tiffani L. Doerr, P.G. Project Manager

Coordinate System: NAD 1983 StatePlane Pennsylvania South FIPS 3702 Feet, North American Vertical Datum of 1988 (NAVD 88)Source: StantecCallouts denote corrected groundwater elevation in feet. Depth to groundwater was measured in each well to the nearest one-hundredth of a foot using an interface probe. PES Complex groundwater remediation systems were in operation during well gauging.Groundwater elevation data was interpolated using block kriging with a linear variogram model in Surfer.Wells not measured during the June 2020 event are not displayed and include (but not limited to) damaged wells, destroyed wells,inaccessible wells, wells with pumps, and wells that were gauged but dry.Wells gauged during June 2020 but not utilized for water-table contouring include those containing measurable light, non-aqueous phaseliquid, wells screened across a fill-supported perched aquifer, wells intersecting more than one water-bearing unit, wells with fouledscreens, a subset of the remediation system wells, and wells excluded from contouring in recent Remedial Investigation Reports. Wells notused for contouring are not displayed.Contour Interval = 1 footAerial & Topo Copyright:© 2013 National Geographic Society, i-cubedPictometry International Corp, Philadelphia Imagery 2018 downloaded from Pennsylvania Spatial Data Access (PASDA)

AOI = Area of Interest

LNAPL = Light non-aqueous phase liquid

ft = Feet

btoc = Below top of casing

NAVD 88 = North American Vertical Datum of 1988

--- = LNAPL not present

NM = Field reading not measured and/or corrected groundwater elevation not calculated due to lack of

surveyed reference elevation or well was dry or presence of down-well pump.

Groundwater and LNAPL Recovery Systems Operational Data

From January 24 to January 31, the system was taken out of service while repairs were made to the system manifold.On March 13, the system was operational, however, due to inadequate flow rate to engage flow meter, no recovery was recorded.On March 17, the system flow meter was replaced. Recovery during this period was estimated using the average recovery during 2019 and 2020. Additionally, RW-4 was removed from operation due to a damaged discharge line. On March 27, the RW-4 pump was repaired and returned to service.On April 30, a pump was installed in RW-23 for groundwater and LNAPL recovery.On May 15 and May 19, the pump in RW-24 was inoperable. The pump was cleaned and returned to service.

The Belmont Terminal Remediation System consists of the Loading Rack system (RW-4 and RW-21 through RW-25) and the Frontage Road system (RW-15 and RW-26 through RW-32). Both systems have a dedicated totalizer.On August 30, 2012, the Frontage Road system was turned off and remained off for the reporting period. The system will remain offline unless there is a significant increase of LNAPL in the recovery wells. The recovery wells were routinely gauged, and no product was detected during the reporting period.

Total Fluids Recovery System Operational DataAOI 1: 26th Street North Remediation System

On April 16, the pumps in S-187 and S-191 were inoperable. These pumps were removed for maintenance.On April 23, the pump in RW-400 was inoperable. This pump was removed for maintenance.On April 30, the pump was reinstalled in RW-400 and returned to service.On May 8, the pumps in S-180, S-184, and S-185 were inoperable. S-185 pump was replaced, S-180 and S-184 were cleaned, and all pumps, including S-187 and S-191, were returned to service.

The 26th Street North Remediation system consists of 20 total fluids recovery wells [15 active wells onsite along 26th Street (S-180, S-181, S-182, S-183, S-184, S-185, S-186, S-187, S-188, S-189, S-190, S-191, S-192, RW-400, & RW-402) and five inactive wells offsite on CSX property (S-193, S-194, S-265, S-267, & S-268)]. The offsite wells on the CSX property have not been activated. The system discharges directly to a process sewer; therefore, the volume of recoverable LNAPL cannot be quantified.

S-182 and S-192 pumps were removed for cleaning and were not in service at the beginning of the reporting period. On February 11, the pumps were reinstalled in S-182 and S-192 and returned to service.


On February 21, the flow rate was not collected because the system flow valves were frozen apon arrival. The flow rate collected on February 11 was used during this period.On February 28, the pumps in RW-402, S180, S-183, and S-190 were inoperable. RW-402, S-183, and S-190 were cleaned and returned to service.On March 6, the pump in S180 was repaired and returned to service. The pumps in S-191 and S-192 were inoperable. S-191 and S-192 pumps were cleaned and returned to service.

AOI 2: Pollock Street Horizontal Wells

First Half 2020

Pump tests were performed in March 2011 for the horizontal wells so that recovered volumes could be estimated based on flow rates and system up-time, beginning in the second quarter of 2011. A second pump test was completed following the installation of a new pump at HW-1 on May 13, 2013. The HW-1 flow rate was estimated at 10 gallons per minute (gpm), HW-2 at 3.73 gpm, and HW-3 at 15.38 gpm. Beginning May 25, 2013, HW-1 flow is measured and reported by a totalizer. HW-2 flow is measured and reported by a totalizer as of July 6, 2015.

* The system discharges directly to a process sewer; therefore, the volume of recoverable LNAPL cannot be quantified.

On June 1, HW-1 was inoperable due to a motor malfunction. HW-1 was taken out of service for maintenance and remained off through the end of the reporting period.

The system was operational during the reporting period with the following exceptions:On November 5, 2019, the pump for HW-2 was removed for repairs. On January 14, 2020, the pump for HW-2 was reinstalled and returned to service, however, the flow meter was removed for repairs. On January 27, the HW-2 flow meter was repaired and reinstalled. HW-2 recovery between January 14 and January 27 was estimated using the average recovery during 2019.On May 12, the HW-2 flow meter was repaired and reinstalled.

The PGW Border Remediation System consisting of 31 recovery wells was started on February 20, 2020. Groundwater and LNAPL are extracted using pneumatic pumps, and total fluids pass through an oil/water separator (OWS). The groundwater is discharged to a facility process sewer and LNAPL is recovered in a 550-gallon storage tank.
