Greensboro Terminal #1760 7115 West Market Street Greensboro, North Carolina 27409 Executive Summary and Introduction Groundwater and Environmental Services, Inc. (GES) is pleased to submit this Annual Monitoring Report to the North Carolina Department of Environmental Quality (NCDEQ) and Guilford County on behalf of RETIA USA, LLC (RETIA), for the site located at 7115 West Market Street, Greensboro, North Carolina (NCDEQ site ID #5067). RETIA is a subsidiary of TotalEnergies Petrochemicals & Refining USA, Inc. (TEPRI), formerly Total Petrochemicals & Refining USA, Inc. (TPRI), with specific responsibility for remediation and risk management activities at former and current TEPRI sites. The location of the property (herein referred to as the “site”) and surrounding topography is provided in Figure 1. The purpose of this site assessment is to: • Discuss the extent of post-remediation contaminants of concern (COCs), and evaluate potential groundwater transport mechanics in order to refine the Conceptual Site Model (CSM); • Present results of semi-annual and annual groundwater monitoring and sampling activities conducted for site wells in order to assess current groundwater quality conditions and to establish trends for a future monitoring plan; • Evaluate the measured liquid levels and light non-aqueous phase liquids (LNAPL) characteristics at off-site wells near the barrier wall; and • Evaluate and quantify contaminant mass flux across the site using a transect-based method, to support formulation of a long-term risk management strategy for the site. This report summarizes a brief history of the site, the methods utilized for additional site characterization, presents the data and findings of the additional investigations, and presents appropriate steps to define the near-term path forward for the site. Initial environmental investigations were conducted between 1990 and 1995 at the site, when it was determined that soils and groundwater were impacted by petroleum hydrocarbons from historical activities. In response to a Notice of Violation (NOV) issued on April 15, 1993, by the North Carolina Department of Environment and Natural Resources (NCDENR, now NCDEQ), Division of Environmental Management, a Comprehensive Site Assessment (CSA) was conducted and submitted in 1993. Incident No. 5067 was issued for the site. In late 1996, TEPRI installed an in situ vacuum-enhanced recovery system (i.e., bioslurping) that extended from its property across West Market Street onto the Piedmont Triad International Airport (PTIA) property to the north. The eastern-most part of the PTIA property is both topographically downslope and hydraulically downgradient of the site. In addition to the bioslurping system, a barrier wall was installed in 1997 under a Corrective Action Plan Addendum (CAPA) to prevent the migration of LNAPL to a pond on the PTIA property. Following the completion of an updated CSA and evaluation of pilot test data by Arcadis in 2004, a thermal remediation technology, using Electro Thermal Dynamic Stripping Process™ (ET-DSP™), was selected to remediate the on-site source area. GES summarized the remedial design for ET- Annual Monitoring Report Former Greensboro Terminal #1760 7115 West Market Street Greensboro, North Carolina 27409 DSP™ in the Source Area Removal Workplan – 2005. The workplan was approved in 2005 by the NCDENR (now NCDEQ), Winston-Salem Regional Office Aquifer Protection Section, and Guilford County. The system’s infrastructure construction was completed in January 2007 and the ET-DSP™ system became fully operational for Zone 1 in March 2007. The area was divided into four separate zones for sequential treatment. Zone 1 operations were completed in December 2007; Zone 2 operations were completed in April 2009; Zone 3 operations were completed in June 2010; and Zone 4 operations were completed in October 2012. The in situ thermal remediation (ISTR) system removed an estimated 880,000 pounds (lbs) of petroleum hydrocarbon from the subsurface. The ISTR strategy achieved its objectives in the treatment zones by removing approximately 75% of the original baseline petroleum mass and approximately 96% of the original dissolved-phase benzene mass. The NCDENR Air Quality Permit (No. 09563R01) and the Groundwater Remediation Permit (No. WQ002919) were rescinded in 2013. Additionally, the City of Greensboro closed the grading permit (No. 2299) in June 2015. Subsurface soils at the site are characterized as sandy silt to clayey silt saprolite that has been chemically weathered in situ from underlying, metamorphosed granitic to dioritic parent bedrock. On the former terminal property, the saprolitic materials are present from near ground surface to depths of approximately 70-80 feet below ground surface (bgs) and bedrock is found below these depths. North of West Market Street, the bedrock/saprolite interface is present at depths of approximately 60-100 feet bgs. The local groundwater flow system is dynamic due to its positioning on both a regional and local drainage divide. Interpretive groundwater contour maps prepared for the site indicate that a groundwater high exists near the southeastern boundary of the TEPRI property; this groundwater high extends onto the adjacent (to the southeast) Magellan terminal property. Groundwater flows away from this topographic high, which runs nearly parallel to the southern property boundary line. From a regional perspective, groundwater flow would be expected to mirror surface topography as is demonstrated via local topography and watershed basins (see Figure 2). At the northern end of the site, groundwater generally moves in a north/northwest direction towards a small swale on the PTIA property. Historical liquid level data suggests that this small drainage on the PTIA property influences groundwater flow in the shallow aquifer and is consistent with the typical recharge-discharge model in the Piedmont physiographic province. No potable wells have been identified within the footprint of the known extent of site-related impacts or within the local groundwater drainage basin. There are several natural and man-made surface water bodies including ponds, an unnamed tributary to the northwest and Horsepen Creek to the northeast of the site. The ponds may be discharge points for shallow groundwater aquifers while drainages further downgradient are likely groundwater discharge points for the deeper saprolite and upper bedrock aquifers. The area just beyond the northern property fence line, under the railroad tracks and West Market Street includes multiple underground utilities. Workers performing maintenance on these utilities have little risk of exposure to site-related contaminants due to the average depth to water at approximately 20 feet bgs. Annual Monitoring Report Former Greensboro Terminal #1760 7115 West Market Street Greensboro, North Carolina 27409 This report documents the following activities completed by GES from May 2023 through April 2024: • Four quarterly gauging events of off-site monitoring wells in the vicinity of the barrier wall to measure elevations of groundwater and LNAPL, if present; • Two groundwater monitoring and sampling events of on-site and off-site wells; • Abandonment of two former recovery wells; and • Evaluation of mass flux through data gathering and calculations. The groundwater sampling of monitoring wells located on-site as well as off-site on the PTIA property was conducted in July and December 2023. Due to insufficient water levels for sampling in December 2023, one on-site well (Z2-PZ-09) was sampled in February 2024. The samples were obtained using low-flow sampling techniques, utilizing a submersible or peristaltic pump, and analyzed for a list of 14 volatile organic compounds (VOCs) via United States Environmental Protection Agency (USEPA) Method 8260 including 1,2,4-trimethylbenzene, 1,2-dibromoethane or ethylene dibromide (EDB), 1,2-dichloroethane (1,2-DCA), 2-methyl naphthalene, isopropyl toluene, benzene, chloroform, ethylbenzene, methyl tert-butyl ether (MTBE), methylene chloride, naphthalene, toluene, total xylenes, and tertiary-butyl alcohol (TBA). Select monitoring wells were also analyzed for additional monitored natural attenuation parameters including nitrate/nitrite, sulfate, ferrous iron, manganese, total iron, alkalinity, and methane. Analytical data from semi-annual groundwater monitoring and sampling events suggest that concentrations of primary COCs dissolved in groundwater are decreasing. Despite this decrease, many wells exceed allowable COC concentrations as promulgated in North Carolina Administrative Code (NCAC) Title 15A Subchapters 2L (2L Standards) or Interim Maximum Allowable Concentrations (IMAC) standards. The plume dimensions for some COCs i.e., benzene, toluene, ethylbenzene, and xylenes (BTEX), MTBE, etc. appear to be shrinking. However, in the case of TBA, the plume appears to be expanding, but has also shown an overall decrease in concentrations compared with the 2016 data. In addition to the semi-annual groundwater monitoring and sampling events, quarterly barrier wall well gauging events were conducted in July 2023, September 2023, December 2023, and March 2024. During the gauging event on December 3, 2023, LNAPL was detected at a thickness of 0.07 feet in FPZ-10. This is the first LNAPL detection at that location since May, 2018 and the lowest measured water elevation at that location since late 2017. The groundwater quality data is presented in the context of a mass flux model with a series of five transects representing discrete vertical intervals of the site groundwater flow regime arranged roughly perpendicular to overall groundwater flow. This technique has been documented by the USEPA, United States Geological Survey (USGS), Interstate Technology and Regulatory Council (ITRC) and others as a practical way to evaluate and prioritize site actions by identifying areas within a contaminant plume where contaminant transport may be taking place. Use of mass flux concepts and tools provide a valuable focus to the large volume of data collected for this historically and physically complex site. The Mass Flux Transect Cross Sections and Mass Flux Annual Monitoring Report Former Greensboro Terminal #1760 7115 West Market Street Greensboro, North Carolina 27409 Transect Profiles including the supporting calculation spreadsheets, are included in Appendix A. Further detail is discussed in Section 4 of this report. Annual Monitoring Report Former Greensboro Terminal #1760 7115 West Market Street Greensboro, North Carolina 27409 1 Site History and Characterization 1.1 Introduction The site is located at 7115 West Market Street, Greensboro, North Carolina, and is approximately 10 acres in size. The former Greensboro bulk fuel terminal was originally built in 1952 and was independently operated by Sinclair Oil Company and British Petroleum (BP) through May 1973. Fina Petrochemicals, Inc. a predecessor company of TEPRI, acquired the terminal from BP and operated the facility until November 1990, at which time, the terminal was permanently closed. The fuels commonly stored at the terminal included several grades of gasoline (leaded and unleaded), kerosene, and fuel oil #2. During operation of the terminal, six aboveground storage tanks (ASTs) ranging in capacity from 840,000 gallons to 2,268,000 gallons were used to store refined petroleum products. The petroleum products were delivered to the terminal via underground pipelines owned and operated by Colonial Pipeline Company and Plantation Pipeline Company. A wastewater storage tank, additive tanks, oil/water separators, and five underground storage tanks (USTs) were also used at various times at the site. The USTs ranged from 500-gallon to 2,000-gallon capacity, and were used to store fuel oil, motor fuels, and phase- separated fuels derived from the oil/water separators and loading rack spill containment/vapor recovery systems. The terminal was razed between May 1993 and May 1994. The site is overseen by the Guilford County Health Department – Health and Risk Assessment (HERA) Team. HERA assigned the former Greensboro Terminal site Incident Number (#) 5067, under the Non-UST Section. Guilford County enforces 2L Standards and North Carolina Oil Pollution and Hazardous Substances Control Act. Regulatory guidance, Guidelines for Initial Response and Abatement, Assessment, and Corrective Action for Non-UST Releases of Petroleum (Guidelines), was issued by NCDNER (now NCDEQ) in July 2012 (effective date July 1, 2012). In accordance with the 2L Standards and Guidelines, the groundwater remediation goals specific to the site are established at concentrations equal to or less than the standards outlined in 15A NCAC 2L.0202. The Guidelines also discuss the need for a Corrective Action Plan (CAP) and the alternative CAPs allowed under NCAC 2L.0106 (k) or .0106 (l). The alternate CAPs (k-CAP or l-CAP) allow for NCDEQ to approve a CAP without requiring groundwater remediation to the 2L Standards or a plan based upon natural processes of degradation and attenuation of contaminants. Currently, the TEPRI property is vacant and undeveloped. The adjacent, downgradient portion of the PTIA property is also undeveloped. A total of 136 wells exist on-site and off-site for the purpose of monitoring groundwater conditions. The well network includes 21 remediation wells, 27 monitoring wells, and seven piezometers on-site and 81 monitoring wells off-site. A generalized Site Map showing the locations of the existing monitoring well network is included as Figure 3. The former site features are shown on Figure 4. Annual Monitoring Report Former Greensboro Terminal #1760 7115 West Market Street Greensboro, North Carolina 27409 1.2 Site Geology, Topography, and Hydrology The former Greensboro Terminal is a rectangular piece of property with the approximate dimensions of 520 feet by 840 feet (10 acres). The site is generally flat with a slight downward slope to the north towards Market Street and the PTIA property. The ground surface elevation is approximately 900 feet above mean sea level (amsl). Railroad tracks and a utility corridor run along the northern boundary of the site. The site lies astride or just north of a drainage divide (as mapped by Guilford County) that is oriented northwest to southeast as shown on Figure 2. The local topography slopes from an elevation of 900 feet amsl on-site to an elevation of 834 feet amsl off-site near the confluence of two unnamed branches of Horsepen Creek north of Old Friendly Road, approximately 2,900 feet north/northeast. To the south and southwest of the site, topography slopes to an elevation of approximately 840 feet amsl near the confluence of two unnamed tributaries of the East Fork Deep River. Surface water drains on-site to the north. Topography to the northwest, towards the PTIA is generally the same elevation as the site along the drainage divide and surface water flows to the north. Areas to the east of the site are generally at a higher elevation along the drainage divide. A detailed topographic map demonstrating these relationships is included as Figure 2. Guilford County is located within the Carolina Slate Belt (Guilford County Groundwater Monitoring Network Status Report, June 2007). The site is located above a metamorphosed igneous intrusion described as metacrystic, well foliated, metamorphosed granitic rock. A geologic contact with non-metamorphosed granite is mapped to the northwest of the site near the PTIA. The contact is generally oriented from the southwest to the northeast. Subsurface soils at the site are characterized as sandy silt to clayey silt saprolite that has chemically weathered in situ from the underlying, metamorphosed parent bedrock. On the terminal property, the saprolitic materials are present from just below the ground surface to depths of approximately 70-80 feet bgs. The installation of 12 soil borings and subsequent monitoring wells in December 2017 and January 2018, demonstrated the saprolite layer to the north of West Market Street on the PTIA property is more variable in thickness and depths to bedrock vary widely, ranging from 57-100 feet bgs. The overburden saprolite is micaceous and contains relict structures of the parent rock including mineral veins, fractures, and metamorphic foliation planes. These structures may form secondary porosity and permeable micro-conduits that can affect contaminant migration and distribution. Grain size analyses performed on two direct-push technology (DPT) samples collected in April 2003 indicated that the saprolite soils in the area are predominately fines. One sample was located on-site and the other was from the off-site PTIA property. Both samples were collected from depths within the historical smear zone located between the historical high and low water table elevations. Results from the analyses indicated that the saprolitic soils can be greater than 90 percent silt and clay. The saprolite is defined as a dual-porosity, fractured, porous medium, which may locally contain small macropores. No subsurface investigative work conducted at the site to date (to include the PTIA property) has yielded evidence of fractures or other structural Annual Monitoring Report Former Greensboro Terminal #1760 7115 West Market Street Greensboro, North Carolina 27409 features in the saprolite or underlying bedrock that would represent preferential groundwater flow pathways, 1.3 Sensitive Receptors In 2013, RETIA commissioned GES to conduct a preliminary risk assessment study to identify all sensitive receptors in the area. Potential off-site receptors were identified utilizing a combination of office and field reconnaissance tasks. The local Guilford County Well Records were reviewed, and GES personnel conducted a windshield receptor survey over an area that encompassed the local drainage basin. The windshield survey was used to identify potential undocumented wells as well as to confirm the location of potential wells identified in an Environmental Essentials Package obtained by GES from Environmental Data Resources, Inc. (EDR) and Guilford County files. The EDR package was submitted in the subsequent reports submitted to the NCDEQ and Guilford County. No potable wells have been identified within a half mile of the footprint of the known extent of site- related impacts or within the groundwater drainage basin. There are several surface water bodies including man-made ponds, unnamed tributaries to Horsepen Creek and Horsepen Creek to the north of the site. The ponds may be groundwater discharge points for shallow groundwater aquifers while drainages further downgradient are potentially groundwater discharge points for the deeper saprolite and upper bedrock aquifers. During the windshield survey, flowing water was identified in the unnamed tributaries of Horsepen Creek at a time of limited rainfall which suggests that the stream is fed by local groundwater discharge. An evaluation of groundwater and surface water elevations further supports this relationship. The area just north of the TEPRI property fence line, under the railroad tracks and West Market Street includes multiple underground utilities. Workers performing maintenance on these utilities have little risk of exposure to site-related contaminants due to the average depth to water at approximately 20 feet bgs. According to the National Wetlands Inventory map in the EDR Report previously referenced, a small wetland exists immediately south and adjacent to the man-made pond on the PTIA property, north of the site. The pond itself is not listed. The pond and adjacent wetlands may be considered potential receptors. Historical sampling data from 2006 indicates the pond was not impacted by petroleum hydrocarbon compounds at that time. Additional data collected from surface water sampling at the off-site stream/pond interface (SG-1) in 2018 and 2020, indicate the surface water is also integrated with the local, shallow groundwater system and is not impacted by any of the site-specific VOCs. Current data from the furthest downgradient monitoring well before the pond, FPZ-5, indicates shallow groundwater is not affected by petroleum hydrocarbons, suggesting discharge to the pond is also free of such impacts. Additionally, the 12 monitoring wells north of the pond (configured in three clusters of four wells each at shallow, intermediate, deep saprolite and bedrock intervals) indicate no impacts of petroleum hydrocarbons above applicable regulatory standards. No other potential receptors were identified within the drainage basin comprising the TEPRI site. Annual Monitoring Report Former Greensboro Terminal #1760 7115 West Market Street Greensboro, North Carolina 27409 1.4 Surrounding Properties and Releases Adjacent to the TEPRI property are two other former bulk fuel storage terminal properties: the former Amoco Oil Company (Amoco) to the east and the former Phillips Pipeline Company (Phillips) to the west. The former Amoco terminal has been reactivated and is currently owned and operated by Magellan Terminals Holdings, L.P. (Magellan). The former Phillips property is now owned by AAA Cooper and is vacant. These adjacent areas are shown on the Local Area Map included as Figure 5. The PTIA property, located north of the TEPRI property, is impacted by petroleum constituents that likely originated from multiple sources. The PTIA property is separated from the TEPRI property by the Southern Railway rail line and West Market Street. A surface water impoundment and intermittent stream (drainage ditch) exist on the PTIA property (Figures 3, 4, and 5). GES obtained an EDR report that included an EDR Aerial Photo Decade Package. The 1955 photo in the EDR report previously provided, shows the pond was created by a man-made dam/berm. 1.4.1 Magellan Terminal Property – EDR Report Review The Magellan terminal property has documented hydrocarbon impacts at the facility; BP/Amoco retains the environmental liability for past hydrocarbon releases at that location. The EDR package also included an EDR Radius Map™ Report with Geocheck®. The EDR report was included in monitoring reports previously submitted to the NCDEQ and Guilford County. The following incidents associated with the Magellan terminal property were noted: • The Leaking Aboveground Storage Tank (LAST) database lists Greensboro Terminal II being associated with contamination in groundwater from an aboveground source. The leak was reported by BP Products of North America on October 16, 1989, and incident Number 5068 was issued. The incident was reported to be closed. No additional information was provided in the EDR report. • The Leaking Underground Storage Tank (LUST) database lists Greensboro Terminal II being associated with petroleum contamination in soil from an underground source. The leak was reported by Atlantic Richfield Co, on December 20, 1991, and incident Number 7871 was issued. The incident was reported to be closed out on December 15, 1993. No additional information was provided in the EDR report. • The Incident Management Database (IMD) database lists Amoco Tank Farm being associated with off-site contamination in groundwater from gasoline, diesel, and/or fuel oil. A NOV was issued on April 28, 1993. No additional information was provided in the EDR report. 1.4.2 Former Phillips Terminal The former Phillips terminal to the west has been closed and razed. The northern portion of the former Phillips terminal is now a vacant grassy field owned by AAA Cooper Transportation. This Annual Monitoring Report Former Greensboro Terminal #1760 7115 West Market Street Greensboro, North Carolina 27409 area is enclosed by a fence and also serves as the entrance to the TEPRI property. The southern portion of the former Phillips terminal is now owned and operated by AAA Cooper Transportation as a commercial trucking depot and repair facility. The former Phillips site is bordered to the south by the Welsh Paper Company. An underground pipeline easement abuts the site and a documented product release occurred from this pipeline along the TEPRI property boundary (see below). There are two documented releases from the Phillips property (Monitoring Report January – August 2016, ATC Associates of North Carolina, 2016). A gasoline release from the loading rack reported in 1987 that received a no further action letter in 2005, and a heating oil/kerosene release from the pipeline connection located along the eastern portion of the former Phillips property reported in 1987. The pipeline release was assigned Groundwater Incident No. 14636 by the NCDEQ. On March 1, 2016, the NCDEQ initiated a regulatory change that allows for risk-based closures at non-UST releases with no free product. The Former Phillips Terminal is pursuing risked based closure for the pipeline release (IN# 14636). The receptor survey was updated with water supply wells, well houses, water meters, and surface water bodies. Research has indicated the site is low risk and there are no water supply wells within 1,000 feet of the site and no “notable” surface water bodies within 500-feet of the site. In May and June 2018, the consultant conducted additional soil and groundwater sampling activities and subsequently submitted the September 24, 2018 Site Closure Request Report to Guilford County, under a risk-based scenario with a notice of residual petroleum. It is TEPRI's understanding that a CAP, in accordance with Title 15A NCAC 2L .0106 to address soil and groundwater impacts associated with the petroleum pipeline release, has never been developed for this release. The plume is monitored on a semi- annual basis. 1.4.3 Other Documented Releases Additional releases have been documented in the Assessment of Active On-Site and Off-Site Remediation Systems and Contributions from Multiple Off-Site Source Areas Report (Arcadis, 1998). The report identifies over 17 separate releases that occurred on adjacent properties or on-site prior to TEPRI’s ownership. Excerpts from the report, including Figure 1-2: Terminal- Complex Map with Areas Impacted by Known Off-Site Releases and Table 3-1: Known Off-Site Releases and On-Site Releases Prior to Fina’s Ownership, Fina Oil and Chemical Company (#1760), Greensboro, North Carolina, were included in monitoring reports previously submitted to the NCDEQ and Guilford County. The largest documented releases from the Arcadis report are summarized below: • May 1966 – Approximately 7,000 gallons of diesel fuel was released to the ground surface when a train collided with a tanker truck. Most of the fuel was not recovered, and the fuel reportedly ponded in ditches and absorbed into surface soils. • 1969 – Approximately 2,500 to 3,000 gallons of diesel fuel were released to the ground surface due to an accident involving a tanker truck on the Amoco property. The Fire Annual Monitoring Report Former Greensboro Terminal #1760 7115 West Market Street Greensboro, North Carolina 27409 Department washed the fuel into surface ditches along Market Street. Substantial quantities of product accumulated in the front ditch and absorbed into the ground. • July 1977 – Approximately 5,000 gallons of gasoline were released to the surface ditches along West Market Street when a train collided with a tanker truck. The Fire Department washed the fuel into surface ditches along West Market Street and then attempted to recover fuel and contaminated wash-down water the following day. According to this information, contaminated soil was left in place. • 1981 – Approximately 7,500 gallons of gasoline were released along the front boundary of the former TEPRI terminal, when a train collided with a tanker truck at the Gallimore Dairy Road crossing. Attempts to salvage the product were made. • July 1997 – Approximately 5,000 gallons of gasoline were released to the surface ditches along Market Street when a train collided with a tanker truck. The Fire Department washed the fuel into surface ditches along Market Street and then attempted to recover fuel and contaminated wash water the following day. According to the information provided, the contaminated soil was left in-place. 1.5 Previous Investigations Initial environmental investigations at the site were conducted between 1990 and 1995 and determined that soils and groundwater were impacted from historical activities at the former TEPRI terminal. In response to a NOV issued on April 15, 1993 by the NCDENR (now NCDEQ), a CSA was conducted and submitted in 1993. Incident No. 5067 was assigned for this site by Guilford County HERA. TEPRI completed additional soil and groundwater assessment activities in 2004. These additional activities were recommended in the 2003 CSA Report - Phase II prepared by Arcadis G&M of North Carolina, Inc. (Arcadis), to further assess the horizontal and vertical extent of petroleum constituents within soil and groundwater below the site and adjacent properties. A Membrane Interface Probe (MIP) survey was conducted at 57 sample locations on the TEPRI, AAA Cooper, and PTIA properties, to assist with delineation of hydrocarbons in the subsurface. The MIP data points collected between April and May 2003 provided a snapshot of the lateral and vertical extent of relative hydrocarbon concentrations and provided a preliminary spatial outline of the source area. The former source zone is described in the August 2005 Source Area Removal Workplan (GES), approved by NCDENR (now NCDEQ) in an October 12, 2005 correspondence. The volumetric extent of the “source area” was refined as data were collected during the execution of ET-DSP™ efforts. An extensive “smear zone” was identified across the site based on soil data, MIP survey data, and historic water table fluctuations. The initial (pre-remediation) source mass was estimated to be over 1.1 million pounds (192,000-gallon equivalent). The smear zone was Annual Monitoring Report Former Greensboro Terminal #1760 7115 West Market Street Greensboro, North Carolina 27409 approximately 260,000 square feet (6 acres) and roughly 12-feet thick in the terminal area and included the free oil zone bounded above and below by residual oil zones. Preliminary delineation of the horizontal and vertical extent of impacts on-site and off-site (AAA Cooper and PTIA sites) was conducted using the flame ionization detector (FID) response data collected during the 2003 MIP investigation. The highest levels of FID responses were observed on the terminal site and the northeastern corner of the AAA Cooper property. The results of the MIP investigation further defined the extent of the “smear zone” located along the site and adjacent properties, and indicated decreasing impacts at depths below approximately 25 to 30 feet bgs (bottom of smear zone) as shown in Appendix B. The smear zone extended from near the southern property boundary to the hydrocarbon interceptor trench located to the north on the PTIA site. As discussed in Section 1.6, extensive source remediation efforts were implemented for the on- site source area. Residual source mass likely exists in areas that were not affected by thermal remediation. These areas include the on-site area just to the north of Zone 4, the area underlying the railroad tracks and below West Market Street. The 2004 CSA Report – Phase III (Submitted by Arcadis, June 2005), provides a description of subsequent investigative activities conducted from March through October 2004, including aquifer testing, installation and sampling of six groundwater monitoring wells, an annual groundwater sampling event, a subsurface soil investigation on the adjacent AAA Cooper and PTIA properties, and a comprehensive investigation of the drainage features on the PTIA property. Additionally, in an ongoing effort to evaluate technologies that may be used for source area remediation of the site, Arcadis also documented the findings of three remedial pilot studies conducted in 2004. The pilot studies were conducted to address remediation of the primary source area. The pilot tests included a combined dewatering/high-vacuum extraction test (conducted by Arcadis), a combined air sparge/high-vacuum extraction test (conducted by Arcadis), and an aggressive in- situ thermal remediation study using ET-DSP™ (conducted by GES). Each of the pilot studies were effective in recovering hydrocarbons from the subsurface, and a brief description of the results of the combined dewatering/high-vacuum extraction test and the combined air sparge/high-vacuum extraction test is included in the 2004 CSA Report – Phase III (Submitted by Arcadis, June 2005). An additional soil investigation was conducted by GES in February and March 2005, to further delineate both vadose zone and saturated zone soil impacts (vertically to the lowest historical water table elevation) across the assumed “source area” located on the TEPRI and AAA Cooper properties. The 2015 Comprehensive Site Assessment Report (Submitted by GES, March 2016), submitted to Guilford County and the NCDEQ, provides a description of subsequent investigative activities conducted from January through December 2015, including a surficial geophysical survey, installation and sampling of 27 groundwater monitoring wells, a site-wide comprehensive groundwater sampling event, LNAPL baildown testing, and LNAPL fingerprinting. Additionally in Annual Monitoring Report Former Greensboro Terminal #1760 7115 West Market Street Greensboro, North Carolina 27409 the 2015 Comprehensive Site Assessment Report, a Sampling and Analysis Plan (SAP) and Mass Flux Work Plan were included. In an April 11, 2016 correspondence, the NCDEQ acknowledged receipt of the 2015 Report and approved the Mass Flux Work Plan as the basis for developing a new remedial action plan for the site. In the correspondence, the NCDEQ also requested additional information with regards to the LNAPL detected in monitoring well FPZ-10, for developing a free product recovery strategy. TEPRI addressed the NCDEQ’s April 11, 2016 correspondence with the July 6, 2016 submittal of the Response to NCDEQ Acknowledgement of Report Receipt. In a correspondence dated July 26, 2016, the NCDEQ approved the recommendations made in the in the 2015 Comprehensive Site Assessment Report for additional assessments and remediation activities at the site. Copies of the NCDEQ correspondences were included in the 2015 Comprehensive Site Assessment Report. The 2017 Annual Monitoring Report / Comprehensive Site Assessment Report (GES, August 2017), submitted to Guilford County and the NCDEQ, provides a description of subsequent investigative activities conducted from January 2016 through April 2017, including the installation and sampling of 18 groundwater monitoring wells, semi-annual site-wide comprehensive groundwater sampling events, and quarterly liquid level gauging of off-site monitoring wells at the barrier wall to measure elevations of groundwater and LNAPL. Additionally in the 2017 Annual Monitoring Report / Comprehensive Site Assessment Report, an updated SAP was included. In a September 25, 2017 correspondence, the NCDEQ acknowledged receipt of the 2017 Report and approved the proposal to install three additional monitoring well clusters to delineate the extent of contaminant plumes downgradient on the PTIA property for completing mass flux estimates. The 2018 Annual Monitoring Report / Comprehensive Site Assessment Report (GES, May 2019), submitted to Guilford County and the NCDEQ, provides a description of subsequent investigative activities conducted from May 2017 through April 2018, including the installation and sampling of 12 groundwater monitoring wells, semi-annual site-wide comprehensive groundwater sampling events, and quarterly liquid level gauging of off-site monitoring wells at the barrier wall to measure elevations of groundwater and LNAPL. Additionally in the 2018 Annual Monitoring Report / Comprehensive Site Assessment Report, an evaluation of mass flux through data gathering and calculations was included. On December 17, 2018, three wells were abandoned including on-site extraction well Z1-X09 and off-site monitoring wells FMW-19 and OW-5. Additionally, attempts to locate on-site piezometer Z4-PZ-10 were conducted; however, it could not be found. On January 8, 2019, the Well Abandonment Records were submitted to Guilford County, and the Monitor Well Construction Permit was subsequently amended from 141 to 138 permitted wells per a January 11, 2019 correspondence from Guilford County to TEPRI. Since on-site extraction well Z1-X09 was not on the current permit and on-site piezometer Z4-PZ-10 has been missing and presumably destroyed since April 2013, the current permit for 138 wells is still valid. Annual Monitoring Report Former Greensboro Terminal #1760 7115 West Market Street Greensboro, North Carolina 27409 On June 12, 2020, GES and RETIA requested approval from Guilford County to suspend monitoring and sampling of 21 select monitoring wells included in the approved Monitor Well Construction Permit #143-96-MW115-RW23. The 21 monitoring wells demonstrated at least six semi-annual rounds of either non-detect results or had minor detections below the NCAC 2L and IMAC standards of all site-specific dissolved petroleum compounds. Additionally, the 21 monitoring wells are not part of the ongoing mass flux evaluation for the site. In an email correspondence on June 12, 2020, Guilford County approved the request. GES conducted an evaluation of the magnitude and extent of residual hydrocarbon impacts on the PTIA and TEPRI properties following completion of ISTR in 2012. Based on the most recent groundwater sampling events conducted from 2013 through 2023, data indicates that the dissolved-phase impacts to the shallow groundwater interval have been greatly reduced on the TEPRI property. With the recent installation of the new monitoring well clusters on the PTIA property, the data gaps that were previously reported have been largely resolved. Such data gaps included determining the extent of off-site residual impacts underlying the space around West Market Street and the railroad tracks to the north of the site (i.e., between on-site and off- site monitoring wells), potential discharge and recharge locations of groundwater to surface water bodies off-site, and the vertical and horizontal distribution of the dissolved-phase TBA plume and TBA migration potential – particularly within the deep saprolite and bedrock hydraulic regimes. It should also be noted that the investigative work completed on-site and off-site in 2015 through 2017 did not yield evidence of soil quality in excess of industrial risk standards for the entire suite of compounds analyzed. 1.6 Summary of Remedial Activities In late 1996, TEPRI installed a vacuum-enhanced recovery system (bioslurping) that extended from its property onto the neighboring Phillips property. The bioslurping system was operational from January 1997 until 2005. The system consisted of more than 27 single and dual-screen recovery wells covering an area of approximately 2.75 acres. The bioslurping system generated liquid and gas waste streams, which were treated in separate treatment units. The soil gas was removed in a knockout tank upstream of the water treatment equipment. The recovered petroleum product was phase-separated from the groundwater in an initial settling tank and later in an oil/water separator. The dissolved-phase contaminants were removed from the groundwater by an air stripping system. The bioslurping system was decommissioned and dismantled in 2005. In addition to the bioslurping system, a hydrocarbon interceptor wall was installed under a CAP Addendum in 1997 on the PTIA property, to prevent the migration of LNAPL into the downgradient pond. The location of the hydrocarbon interceptor wall is depicted on Figures 2, 3, and 4. Pneumatic oil skimming pumps were also used in two recovery wells (RW-1 and RW-2) on the PTIA property to remove any accumulated product within the permeable backfill upgradient of the hydraulic barrier wall. The hydrocarbon interceptor wall remains in place, but LNAPL recovery operations from recovery wells RW-1 and RW-2 was discontinued in approximately 2014. Existing monitoring wells and piezometers in the vicinity of the barrier wall on the PTIA property are gauged on a quarterly basis to verify that LNAPL has not migrated past this wall. LNAPL was Annual Monitoring Report Former Greensboro Terminal #1760 7115 West Market Street Greensboro, North Carolina 27409 last detected in RW-2 in January 2004 at an in-well thickness of 0.02 feet. No record of LNAPL accumulation exists for RW-1. LNAPL has not been observed in the area of the interceptor trench since 2018 and has not been observed in any on-site wells since 2013. Following the completion of the CSA in 2004 and evaluation of the pilot test data mentioned in Section 1.5, ISTR using ET-DSP™ technology was selected to remediate the source area. The remedial design for ET-DSP™ was summarized in the Source Area Removal Workplan (GES 2005). The workplan was approved by NCDNER (now NCDEQ) Winston-Salem Regional Office Aquifer Protection Section and Guilford County in 2005. The ET-DSP™ technology is a licensed/patented technology implemented by McMillan-McGee Corporation (Mc2) of Calgary, Alberta Canada. ET-DSP™ is a remediation technique, similar to electrical resistance heating (ERH), in which electricity is supplied to buried electrodes to create a heated zone in the subsurface. When using the ET-DSP™ technology, heat is generated within an electrode field due to soil properties that resist the transfer of electricity. The resultant heat vaporizes water and petroleum hydrocarbons and generates in situ steam that serves to transport subsurface volatile and semi-volatile compounds to the surface. Soil Vapor Extraction (SVE) or Multi-Phase Extraction (MPE) techniques are then used to capture the gasses and liquids driven off by heat for aboveground treatment. The construction of the thermal remediation system was completed in January 2007. The treatment area was divided into four separate zones for sequential treatment. Zone 1 operations were completed in December 2007; Zone 2 operations were completed in April 2009; Zone 3 operations were completed in June 2010; and Zone 4 operations were completed in October 2012. The ISTR strategy removed an estimated 880,000 pounds of petroleum hydrocarbon mass, including 657,000 pounds (75%) recovered in the vapor phase; 202,000 pounds (23%) recovered as non-aqueous phase liquid; and 21,000 pounds (2%) recovered as dissolved-phase in extracted groundwater. The ISTR overachieved its stated objectives in the treatment zones by removing approximately 75% (remedial target = 70%) of the original baseline petroleum mass and approximately 96% (remedial target = 93%) of the original dissolved-phase benzene mass. Removing over 70% of the cumulative mass recovered has eliminated the majority of the on-site source area hydrocarbon mass, reduced contaminant flux to groundwater and promoted post- heating petroleum hydrocarbon degradation via aerobic bioremediation. The removal of over 93% benzene will facilitate restoration of groundwater by allowing the upper aquifer to return to aerobic conditions, which will promote further groundwater restoration via monitored natural attenuation. Annual Monitoring Report Former Greensboro Terminal #1760 7115 West Market Street Greensboro, North Carolina 27409 1.7 Site Strategy 1.7.1 Monitoring Well Optimization Due to the extensive monitoring well network at the site (i.e., over 130 wells), GES and RETIA conducted an optimization analysis of the existing groundwater sampling program, using the Monitoring and Remediation Optimization system (MAROS) software package developed by GSI Environmental, Inc. for the Air Force Center for Engineering and the Environment. The MAROS software provides a highly prescriptive process for analyzing and iteratively comparing alternate networks of well sampling for a specific site. MAROS analyzes both temporal and spatial data to provide recommendations for eliminating wells from the sampling program and/or reducing the frequency of sampling. The objective of the MAROS optimization is to minimize the sampling program by eliminating data that provide no significant value to the analysis while ensuring adequate future characterization for the contaminant plume. GES performed an additional spatiotemporal analysis to verify the MAROS determination of trends for both individual wells and overall plume mass estimates. The Groundwater Spatiotemporal Data Analysis Tool (GWSDAT) software package was developed by Shell to provide interpolated groundwater concentrations of specified COCs over time. GWSDAT also allows plume extent thresholds to be specified by the user. If the interpolation provides for complete delineation to the specified threshold, then GWSDAT will calculate the center of mass location as well as estimates of plume mass and average concentration. This output can then be used to evaluate the stability of the plume overall and can help in identifying systemic changes that may indicate new releases and/or off-site plume encroachment. GWSDAT also provides trend charts that plot observed analytical concentrations and confidence intervals for the trend. Using the output provided by MAROS and GWSDAT in conjunction with project-specific knowledge (i.e., key operational remedial system wells, site characterization/delineation wells, and off-site monitoring wells), results indicated the sampling frequency for some wells could be reduced based on sufficient recent and historical data showing low rates of change. There were eight wells that did not show a strong enough decreasing trend to recommend a reduction in sampling frequency at those locations. Additionally, the results indicated that it was feasible to remove 26 wells from the monitoring program as the plume is stable across these wells and most analytes. Currently, 107 wells are sampled on an annual basis and eight wells are sampled semi- annually. The results of the optimization analysis were included in the December 3, 2021 (Rev. January 2022) Groundwater Monitoring Plan Optimization Analysis report submitted to Guilford County. The report was approved in a February 11, 2022 correspondence. Annual Monitoring Report Former Greensboro Terminal #1760 7115 West Market Street Greensboro, North Carolina 27409 1.7.2 New Technology Cleanup Plan A New Technology Cleanup Plan (NTCP) was submitted by GES on behalf of RETIA, to the NCDEQ and Guilford County on November 15, 2022. The purpose of the NTCP was to: • Discuss the extensive history, assessment, and remediation of the site to further evaluate and propose additional remedial options for a long-term site strategy; • Discuss the extent of post-remediation contaminants of concern (COCs), and evaluate potential groundwater transport mechanics in order to refine the Conceptual Site Model (CSM); • Present historical results of soil, groundwater, and surface water monitoring and sampling activities conducted to assess current conditions and to establish trends for a future monitoring plan; • Present risk classification and applicable cleanup goals for soil, groundwater, and surface water; • Discuss results of an ongoing contaminant mass flux analysis across the site to support formulation of a long-term risk management strategy for the site; • Discuss in-place remedial technologies such as the LNAPL barrier wall and natural attenuation and their effectiveness to be viable remedial options, and propose a plan to enhance natural attenuation with an in-situ biostimulation approach; and • Present potential risk based corrective action approaches such as filing a Notice of Contaminated Site for both the on-site and off-site properties. The NTCP was approved in a November 22, 2022 correspondence (incorrectly dated November 22, 2021). 1.7.3 Enhanced In-Situ Bioremediation (EISB) Evaluation A combination of natural attenuation plus the ongoing use of the LNAPL barrier wall is a viable remedial option; however, based on a half-life analysis of data collected from 2012-2021, it would take an extended period of time to achieve the 2L standards and even GCLs if those were approved via a risk reduction mechanism. Therefore, and rather than natural attenuation as the sole remedial process for groundwater contamination, RETIA proposed to undertake an evaluation of the effectiveness of an enhanced in-situ bioremediation (EISB) remedy at locations where mass flux calculations suggest there is significant VOC transport. An EISB Evaluation Work Plan was submitted by GES on behalf of RETIA, to the NCDEQ and Guilford County on January 13, 2023 (later revised on January 25, 2023) to outline work to be completed to evaluate the effectiveness of an EISB remedy. Further understanding the chemical, geochemical, and biological conditions at the site is necessary to assess the potential for EISB. It is important to understand the particular petroleum Annual Monitoring Report Former Greensboro Terminal #1760 7115 West Market Street Greensboro, North Carolina 27409 degrading microorganisms that are present as well as which electron acceptor (oxygen, sulfate, or nitrate) is most favorable towards the existing biological community and geochemical state to ensure the success of an EISB approach. To facilitate this understanding, GES completed additional groundwater sampling and microcosm studies in 2023 to assess the petroleum hydrocarbon and fuel oxygenate degrading capabilities and activities of the naturally-occurring organisms via molecular biological tools (MBTs). MBT studies use laboratory testing to assess whether the indigenous microorganisms are actively degrading contaminants. Data generated from the studies are used to directly support the presence of natural attenuation processes at the site and the ability to enhance the degradation with amendments intended to increase the in-situ microbial population. The data collected for the study are still under evaluation to definitively determine the presence and activity of the naturally- occurring organism under enhanced conditions. Once the study is finalized, an EISB Evaluation Report will be submitted to the NCDEQ and Guilford County under separate cover. 1.8 Report Objectives The objectives of this Annual Monitoring Report include presentation of: • A discussion of the extent of post-remediation COC impacts, and proposed additional measures to evaluate groundwater transport mechanics in order to refine the CSM; • A summary of groundwater monitoring and sampling activities for site wells to assess current groundwater quality conditions and to establish trends for a future monitoring plan; • An evaluation of the measured liquid levels and LNAPL, if present, at off-site wells near the barrier wall on the PTIA property; • An evaluation of the current monitoring well network and sampling frequency, for optimization purposes; and • An assessment of the lateral and vertical integrated network for the purpose of calculating contaminant mass flux. The following subsections summarize the methods utilized for additional site characterization, present the data and findings of the additional investigations, and present the appropriate steps to define the near-term path forward for the site. Annual Monitoring Report Former Greensboro Terminal #1760 7115 West Market Street Greensboro, North Carolina 27409 2 Methodology 2.1 Groundwater Monitoring and Sampling GES conducted quarterly gauging of shallow monitoring wells designated as the barrier wall wells, during events in July 2023, September 2023, December 2023, and March 2024. A total of 30 barrier wall wells were gauged during all events except in March 2024, where only 28 barrier wall wells were gauged. Two former recovery wells, which also served as barrier wall wells, were properly abandoned in February 2024 (see Section 2.3). The quarterly barrier wall well gauging events for July and December 2023, were conducted in conjunction with semi-annual and annual groundwater sampling events. Gauging of the barrier wall well network has been conducted on a weekly, monthly, bi-monthly, and/or intermittent basis since approximately 1997. Results of the barrier wall gauging events are discussed in Section 3.1. Additionally, GES conducted two groundwater monitoring and sampling events at the site in July and December 2023. Due to insufficient water levels for sampling in December 2023, on-site well Z2-PZ-09 was sampled in February 2024. The groundwater monitoring and sampling events were conducted in accordance with the approved SAP (submitted in the 2015 Comprehensive Site Assessment Report), and the approved December 3, 2021 (Rev. January 2022) Groundwater Monitoring Plan Optimization Analysis report, which reduced and/or eliminated the sampling frequency of select site monitoring wells and piezometers. Prior to sampling, liquid-level measurements were collected from each well utilizing an oil/water interface probe. Both the measurements of water and oil, if applicable, were recorded in a field notebook to the nearest 0.01-foot below the TOC. The well construction details along with survey information for each well are included on Table 1. Tables 2 and 3 contain the recorded gauging data and groundwater elevations for on-site and off-site wells, respectively. Between July 17 through 20, 2023, GES personnel monitored and sampled a total of 115 out of 138 permitted wells including, 27 on-site monitoring wells, 19 on-site extraction wells, seven on- site piezometers, and 62 off-site monitoring wells. The remaining 23 extraction wells and/or monitoring wells of the 138 total permitted wells were only gauged and not sampled, per the approved reduction discussed in Section 1.7.1. On December 6, 2023, GES personnel monitored a total of eight out of 138 permitted wells including, one on-site monitoring well, one on-site piezometer, and six off-site monitoring wells. During the event, one well (piezometer Z2-PZ-09) was observed to be dry and therefore, not sampled. The remaining 130 extraction wells and/or monitoring wells of the 138 total permitted wells were not gauged during this event; except for the designated barrier wall wells that are gauged on a quarterly basis. In conjunction with other activities on February 2, 2024, monitoring well Z2-PZ-09 was gauged and subsequently sampled. Groundwater samples were collected from the monitoring wells using the low-stress (low-flow) purging and sampling methods outlined in the SAP. Field geochemical parameters, including pH, electrical conductivity, temperature, dissolved oxygen (DO), oxidation-reduction potential (ORP), and turbidity, were recorded by GES staff in the field. Each well was purged at low-flow rates, Annual Monitoring Report Former Greensboro Terminal #1760 7115 West Market Street Greensboro, North Carolina 27409 approximately 200-300 milliliters per minute (mL/min) until field geochemical parameters had stabilized. The geochemical parameters were measured using a YSI DDS Pro multi-parameter meter using a flow through cell, and the results were recorded at regular intervals in a field notebook. In addition, draw-down was measured utilizing an oil/water interface probe. The stabilized groundwater parameters for each monitoring well are provided in Table 4. Groundwater sampling forms completed during the July 2023 and December 2023/February 2024 sampling events, are included in Appendices C and D, respectively. Groundwater samples, including field duplicates, equipment blanks, and field blanks were collected in either unpreserved or pre-preserved, laboratory-prepared bottleware and placed in a cooler on ice immediately following collection. Equipment blanks were taken daily by running deionized water through the sampling equipment to ensure proper decontamination between wells. Appropriate chain-of-custody documentation accompanied the samples to ALS Environmental located in Houston, Texas. Groundwater sample analysis utilized the following USEPA methods: • Method 8260B: Site-specific VOCs including trimethylbenzene, EDB, 1,2-DCA, 2- methyl naphthalene, isopropyl toluene, benzene, chloroform, ethylbenzene, MTBE, methylene chloride, naphthalene, toluene, total xylenes, and TBA; • Method 8011: EDB; • Method RSK-175: Methane and/or isobutylene; • Method 353.2: Nitrate/nitrite; • Method 9038: Sulfate; • Method 2320B: Alkalinity; • Method 3500F+2B: Ferrous iron; and • Method 6010C: Manganese and iron. The groundwater analytical laboratory reports from ALS Environmental for the July 2023 and December 2023/February 2024 sampling events, are included in Appendices E and F, respectively. Groundwater analytical results are summarized in Tables 5 and 6 for on-site and off-site wells, respectively. The analytical results were then compared to the NCDEQ NCAC2L and/or IMAC standards for petroleum releases for all analyzed VOCs. All purge water and decontamination fluid associated with the sampling event was placed into temporary storage tanks. Following completion of the site activities the sediment suspended in the purge water was allowed to settle out prior to transport. Documentation from A&D Environmental, Inc., for removal and disposal of purge water and decontamination liquids from the July 2023 groundwater monitoring and sampling event is provided in Appendix G. Annual Monitoring Report Former Greensboro Terminal #1760 7115 West Market Street Greensboro, North Carolina 27409 2.2 Surface Water Monitoring During semi-annual and quarterly groundwater monitoring events, GES gathered the surface water elevation from a calibrated stream gauge (SG-1) that was previously installed at the off-site stream/pond interface. Table 3 contains the recorded gauging data and groundwater elevations for stream gauge SG-1. This surface water elevation value is incorporated into the shallow groundwater flow maps provided as Figures 6 through 10. 2.3 Recovery Well Abandonment On February 2, 2024, two off-site wells were abandoned including former recovery wells RW-1 and RW-2. The Well Abandonment Records were submitted to Guilford County via email on February 28, 2024. Per the email correspondence dated May 7, 2024, the Monitoring Well Construction Permit will be amended from 138 to 136 permitted wells. An updated list of permitted wells along with the May 7, 2024 Guilford County correspondence, is provided in Appendix H. Annual Monitoring Report Former Greensboro Terminal #1760 7115 West Market Street Greensboro, North Carolina 27409 3 Site Investigation Results 3.1 Barrier Wall Gauging In May 2023 through March 2024, GES personnel completed quarterly gauging of the shallow monitoring wells designated as the barrier wall wells. Additionally in conjunction with these events, GES gathered the surface water elevation from stream gauge SG-1 at the off-site stream/pond interface. A compilation of these gauging data combined with historical gauging data can be found in Tables 2 and 3. Groundwater elevation maps for the July 2023, September 2023, December 2023, and March 2024 barrier wall well gauging events are included as Figures 6, 7, 8, and 9, respectively. Groundwater flow was shown to be consistent with historical observations, flowing in a northerly direction with localized deflection around the barrier wall. The 2023 and 2024 gauging events completed during this reporting period are summarized below. 3.1.1 Routine Gauging Events Gauging Event Gauging Date: July 17, 2023 Wells Gauged: AMW-11S, AMW-13S, AMW-14S, AMW-15S, AMW-16S, AMW-17S, AMW-18S, DEM-MW6R, FMW-20, FMW-21, FMW-23R, FPZ-5, FPZ-6, FPZ-7, FPZ-8, FPZ-10, FPZ-11, FPZ-12, FPZ-13, FPZ-14, FPZ-15, OW-1, OW-2, OW-3, OW-4, OW-6, OW-7, OW-8, RW-1, RW-2, and stream gauge SG-1 LNAPL: Not present Depth to Water Range: 4.24 (FPZ-5) to 16.14 (DEM-MW6R) feet below top of casing Groundwater Flow Direction: Northeasterly (at close proximity to the barrier wall) and Easterly (at western portion of barrier wall) Groundwater Elevation: 870.55 (FPZ-5) to 877.48 (AMW-14S) Present Hydraulic Gradient: 0.014 feet/foot between AMW-14S and FPZ-5 Gauging Event Gauging Date: September 18, 2023 Wells Gauged: AMW-11S, AMW-13S, AMW-14S, AMW-15S, AMW-16S, AMW-17S, AMW-18S, DEM-MW6R, FMW-20, FMW-21, FMW-23R, FPZ-5, FPZ-6, FPZ-7, FPZ-8, FPZ-10, FPZ-11, FPZ-12, FPZ-13, FPZ-14, FPZ-15, OW-1, OW-2, OW-3, OW-4, OW-6, OW-7, OW-8, RW-1, RW-2, and stream gauge SG-1 LNAPL: Not present Depth to Water Range: 5.31 (FPZ-5) to 18.53 (FMW-20) feet below top of casing Groundwater Flow Direction: Northeasterly (at close proximity to the barrier wall) and Easterly (at western portion of barrier wall) Annual Monitoring Report Former Greensboro Terminal #1760 7115 West Market Street Greensboro, North Carolina 27409 Groundwater Elevation: 869.48 (FPZ-5) to 875.17 (AMW-14S) Present Hydraulic Gradient: 0.011 feet/foot between AMW-14S and FPZ-5 Gauging Event Gauging Date: December 6, 2023 Wells Gauged: AMW-11S, AMW-13S, AMW-14S, AMW-15S, AMW-16S, AMW-17S, AMW-18S, DEM-MW6R, FMW-20, FMW-21, FMW-23R, FPZ-5, FPZ-6, FPZ-7, FPZ-8, FPZ-10, FPZ-11, FPZ-12, FPZ-13, FPZ-14, FPZ-15, OW-1, OW-2, OW-3, OW-4, OW-6, OW-7, OW-8, RW-1, RW-2, and stream gauge SG-1 LNAPL: 0.07 feet in FPZ-10 Depth to Water Range: 6.55 (FPZ-5) to 20.22 (FMW-20) feet below top of casing Groundwater Flow Direction: Northeasterly (at close proximity to the barrier wall) and Easterly (at western portion of barrier wall) Groundwater Elevation: 868.24 (FPZ-5) to 873.43 (AMW-14S) Present Hydraulic Gradient: 0.010 feet/foot between AMW-14S and FPZ-5 Gauging Event Gauging Date: March 1, 2024 Wells Gauged: AMW-11S, AMW-13S, AMW-14S, AMW-15S, AMW-16S, AMW-17S, AMW-18S, DEM-MW6R, FMW-20, FMW-21, FMW-23R, FPZ-5, FPZ-6, FPZ-7, FPZ-8, FPZ-10, FPZ-11, FPZ-12, FPZ-13, FPZ-14, FPZ-15, OW-1, OW-2, OW-3, OW-4, OW-6, OW-7, OW-8, and stream gauge SG-1 LNAPL: Not present Depth to Water Range: 3.30 (FPZ-5) to 17.60 (OW-8) feet below top of casing Groundwater Flow Direction: Northeasterly (at close proximity to the barrier wall) and Easterly (at western portion of barrier wall) Groundwater Elevation: 870.75 (SG-1) to 877.36 (AMW-14S) Present Hydraulic Gradient: 0.012 feet/foot between AMW-14S and SG-1 3.1.2 Historical Time Trend Graphs The groundwater elevation for each gauging event from January 2014 to present was compared to the total amount of precipitation received each month, as depicted in Appendix I. The total monthly precipitation for July 2023 was 3.08 inches. The highest total monthly precipitation over this evaluation period was 7.10 inches in December 2023. In general, a corresponding increase in groundwater elevation is observed after higher total monthly precipitation amounts. Historical monthly precipitation data from 1987 through March 2024 are shown in Appendix I. 3.1.3 FPZ-10 Historical LNAPL Time Trend Graph The LNAPL and groundwater elevation time trend graph for monitoring well FPZ-10 is presented in Appendix I. Monitoring well FPZ-10 is located approximately 40 feet upgradient of the barrier Annual Monitoring Report Former Greensboro Terminal #1760 7115 West Market Street Greensboro, North Carolina 27409 wall. From July 1997 to January 2008, LNAPL amounts ranging from 0.01 feet to 2.27 feet had been detected in FPZ-10. During the gauging event on July 30, 2015, LNAPL was detected at a thickness of 0.17 feet. Prior to July 2015, LNAPL had not been detected since January 2008. During this reporting period, 0.07 feet of LNAPL was detected in monitoring well FPZ-10 during the December 6, 2023 event. During a follow-up field event on February 2, 2024, monitoring well FPZ-10 was gauged and no LNAPL was detected. The December 2023 gauging event represented the lowest groundwater elevation at FPZ-10 since December, 2017. 3.1.4 LNAPL Recovery Efforts Per the approved free product recovery strategy, passive recovery via absorbent socks was initiated in May 2016. Absorbent socks have been replaced as necessary during subsequent gauging events. Currently, absorbent socks are installed in monitoring wells FPZ-10 and FPZ- 15, and will be routinely inspected and replaced as necessary. 3.1.5 Hydraulic Head Distribution Liquid-level measurements were collected using an oil/water interface probe and measured to the nearest 0.01-foot during the quarterly barrier wall gauging and semi-annual groundwater monitoring and sampling events. LNAPL was detected in monitoring well FPZ-10 in December 2023. No other detections of free product were observed during this reporting period. Tables 2 and 3 contain the recorded gauging data and groundwater elevations for on-site and off-site wells, respectively. These liquid-level measurements were used to calculate the groundwater elevation at each monitoring well location. Groundwater elevations for the July 2023 groundwater monitoring and sampling event were utilized to develop shallow, intermediate, deep, and bedrock groundwater elevation contour maps, Figures 10 through 13. Additionally, Figure 14 includes the groundwater elevation contours for the shallow zone from the December 2023 monitoring and sampling event. The maps depict the interpreted groundwater flow at the site at the time of gauging during each event. From the groundwater monitoring and sampling events conducted in July and December 2023, groundwater flow in the shallow, intermediate, deep, and bedrock zones trended from northwest on-site to northeast off-site. In addition, calculations were performed to evaluate the head differences or vertical gradients between adjacent vertical zones in each of the 22 well clusters across the site. These calculations followed a center-of-screen to center-of-screen technique as described by the USEPA (http://www3.epa.gov/ceampubl/learn2model/part-two/on-site/vgradient02.html). A summary of these vertical gradients is provided in Table 7. The gradient value for each identified well is the result of the head comparison/calculation to the well immediately above it in the same cluster. This is discussed in greater detail in Section 4.5. Annual Monitoring Report Former Greensboro Terminal #1760 7115 West Market Street Greensboro, North Carolina 27409 3.1.6 On-Site Concentrations Over Time An evaluation of the extent of on-site residual hydrocarbon impacts over time has been undertaken to visually illustrate contaminant trends over time. Several groundwater monitoring and sampling events from 2006 through 2023, and select contaminants of concern, were used to evaluate the on-site extent and strength of the dissolved-phase hydrocarbon plume prior to, during, and post-ISTR. Based on the most recent groundwater sampling event conducted in July 2023, data indicates that the dissolved-phase impacts to the shallow groundwater interval have been greatly reduced on the TEPRI property. Despite this substantial reduction, exceedances of the relevant state standards still exist in a number of on-site and off-site wells. The following map is provided to illustrate the reduction of on-site shallow dissolved-phase impacts of BTEX over time: • Figure 15: Observed Total BTEX Groundwater Concentrations Over Time 3.1.7 July 2023 Isoconcentration Contours Laboratory analytical results for the July 2023 sampling event are included in Appendix E. Results were tabulated and screened against the NCDEQ NCAC 2L or IMAC standards where applicable and are summarized on Tables 5 and 6. The following isoconcentration maps are provided to illustrate the most recent comprehensive sampling results for the following site- specific analytes: • Figure 16: Groundwater Benzene Concentration Map – Shallow Wells – July 2023 • Figure 17: Groundwater Benzene Concentration Map – Int. Wells – July 2023 • Figure 18: Groundwater Benzene Concentration Map – Deep Wells – July 2023 • Figure 19: Groundwater Benzene Concentration Map – Bedrock Wells – July 2023 • Figure 20: Groundwater TBA Concentration Map – Shallow Wells – July 2023 • Figure 21: Groundwater TBA Concentration Map – Int. Wells – July 2023 • Figure 22: Groundwater TBA Concentration Map – Deep Wells – July 2023 • Figure 23: Groundwater TBA Concentration Map – Bedrock Wells – July 2023 3.1.8 December 2023/February 2024 Groundwater Analytical Results Laboratory analytical results for the December 2023/February 2024 sampling event are included in Appendix F. Results were tabulated and screened against the NCDEQ NCAC 2L or IMAC standards where applicable and are summarized on Tables 5 and 6. Figure 24 provides the results of site-specific analytes for the December 2023 groundwater sampling event. 3.1.9 Cross Sections To better evaluate the volumetric distribution of dissolved impacts, a series of cross sections have been prepared depicting the vertical extent of the monitoring well network (former and current). Where applicable, temporal data have been shown to illustrate the changes in water quality over time. Annual Monitoring Report Former Greensboro Terminal #1760 7115 West Market Street Greensboro, North Carolina 27409 Cross sections were constructed along the seven transects (A-A’, B-B’, C-C’, D-D’, E-E’, F-F’, and G-G’) as shown on Figure 25. Interpreted dissolved benzene contours are shown along each transect on Figures 26 through 32, respectively, and dissolved TBA contours along each transect are shown on Figures 33 through 39, respectively. Note that the cross sections were prepared using data from the July 2023 comprehensive groundwater sampling event. Note that in July 2018, the naming convention for the original transects included in prior reports was revised to keep consistency with the names of the mass flux transects. Transects F-F’ and G-G’ were not used in the mass flux evaluation as they are aligned parallel to groundwater flow. Additionally, and per the August 15, 2019 Guilford County email correspondence, Transects F-F’ and G-G’ were revised to include additional wells to better evaluate plume behavior and/or remove former/abandoned wells. Furthermore, and to satisfy the requirements of the November 2022 NTCP, the naming convention of the transects included in the NTCP differ from those used in Annual Monitoring Reports and the mass flux analysis. On-site, parallel with West Market Street is transect A-A’, which includes several of the monitoring well clusters that were installed in late 2015 (Figures 26 and 33). TBA was detected above the IMAC of 10 micrograms per liter (ug/L) in all zones extending into the upper portion of the fractured bedrock zone (ranging from 89 ug/L in Z3-X80 to 100,000 ug/L in MW-B-B). Benzene was not detected above the NCAC 2L of 1 ug/L in any monitoring well along this transect. On-site, parallel with West Market Street, is transect B-B’, which includes several of the monitoring well clusters that were installed in late 2015 (Figures 27 and 34). Benzene was detected above the NCAC 2L of 1 ug/L in the shallow zone at the MW-E cluster (Z4-X47). Benzene was not detected above the NCAC 2L of 1 ug/L in any of the intermediate or bedrock zones along this transect. TBA was detected above the IMAC of 10 ug/L in the intermediate zone in the MW-H cluster and in the deep zone in the MW-F and MW-G clusters, ranging from 29 ug/L in MW-H-I to 23,000 ug/L in MW-G-B. TBA was not detected in the shallow or bedrock zones. Transect C-C’ is aligned just north of and parallel with West Market Street on the PTIA property. This includes several of the monitoring well clusters that were installed in late 2016 (Figures 28 and 35). Benzene was detected above the NCAC 2L of 1 ug/L in the shallow, intermediate, and deep zones along this transect (ranging from 2.4 ug/L in MW-K-I to 38 ug/L in SBMW-1R). TBA was detected above the IMAC of 10 ug/L in the intermediate, deep, and bedrock zones, centralized around the SBMW-2 cluster (ranging from 120 ug/L in PMW-L-I to 15,000 ug/L in SBMW-2D and SBMW-2B). The SBMW-2 cluster is situated just north of West Market Street. Transect D-D’ on the PTIA property includes several of the monitoring well clusters that were installed in late 2016 (Figures 29 and 36). Benzene was detected above the NCAC 2L of 1 ug/L in the shallow and intermediate zones along this transect (ranging from 4.9 ug/L in FMW-23R to 7,100 ug/L in FMW-24. Benzene was not detected in the PMW-N cluster. TBA was detected above the IMAC of 10 ug/L in the shallow, intermediate, and deep zones (ranging from 280 ug/L in PMW-N-D to 27,000 ug/L in DEM-MW6I). TBA was not detected in the bedrock zone. Annual Monitoring Report Former Greensboro Terminal #1760 7115 West Market Street Greensboro, North Carolina 27409 Transect E-E’ on the PTIA property includes the three monitoring well clusters that were installed in December 2017 and January 2018 (Figures 30 and 37). All monitoring wells along this transect have either been non-detect for all dissolved petroleum compounds or have had minor detections of 1,2,4-trimethylbenzene, EDB, chloroform, naphthalene, and/or toluene, below the NCAC 2L standards. As shown on transect F-F’ (Figures 31 and 38), neither benzene nor TBA were detected in the furthest upgradient source zone well (Z1-X01). Benzene was detected above the NCAC 2L of 1 ug/L in the shallow zone along the northern edge of the former Terminal property at a concentration of 3.2 ug/L in Z4-PZ04, and across West Market Street at a concentration of 14 ug/L in DEM-MW6R. TBA concentrations above the IMAC of 10 ug/L were observed across all zones along this transect (ranging from 89 ug/L in Z3-X80 to 100,000 to ug/L in MW-B-B). At the northeastern portion of the barrier wall along this transect, TBA was detected above the IMAC of 10 ug/L in the shallow zone at a concentration of 7,200 ug/L in FMW-21. TBA was not detected in the MW-A cluster. Across the barrier wall along this transect is FPZ-5, in which sampling at this location was suspended after the December 2019 event. TBA has been non-detect at FPZ- 5 since sampling began. On-site to the west and running parallel with transect F-F’ is transect G-G’ (Figures 32 and 39). This transect runs from the western portion of the site starting in Zone 4, across West Market Street, to the monitoring well FPZ-12 cluster downgradient of the barrier wall. On-site, benzene was detected above the NCAC 2L of 1 ug/L in the shallow zone in Z4-X63 and Z4-X47, at concentrations of 1.1 ug/L and 8.2 ug/L, respectively. Across West Market Street, benzene was detected above the NCAC 2L in the shallow zone in FMW-24, AMW-11S, and AMW-13S, at concentrations of 7,100 ug/L, 2.6 ug/L, and 260 ug/L, respectively. Benzene was detected above the NCAC 2L in the intermediate zone in FMW-24I at a concentration of 5.6 ug/L. Benzene was not detected in the deep and bedrock zones along this transect. TBA concentrations above the IMAC of 10 ug/L were observed across the intermediate, deep, and bedrock zones along this transect, with concentrations ranging from 220 ug/L in PMW-O-I to 1,900 ug/L in AMW-13B. 3.1.10 Groundwater Sampling Results – On-Site Wells The following section presents the water quality results from the July 2023 and December 2023/February 2024 groundwater sampling events of the on-site shallow extraction wells, piezometers, and monitoring wells. The on-site shallow well network consists of 23 extraction wells, seven piezometers, and 27 monitoring wells. As previously discussed in Section 1.7.1, a groundwater optimization analysis was approved by Guilford County in February 2022, and most on-site wells are only sampled on an annual basis. There are a select number of on-site wells sampled semi-annually. During this reporting period, the annual sampling event was completed in July 2023 and the semi-annual event in December 2023. One on-site well had insufficient water for sampling in December 2023; therefore, it was subsequently sampled in February 2024. Annual Monitoring Report Former Greensboro Terminal #1760 7115 West Market Street Greensboro, North Carolina 27409 Historical groundwater analytical results for all existing on-site wells are provided in Table 5. Analytical results of site-specific VOCs in the existing on-site wells during the July 2023 and December 2023/February 2024 groundwater sampling events were observed as follows: • No VOC exceedances were observed in 10 extraction wells and 14 monitoring wells; • One or more of the site-specific VOCs exceeded the NCAC 2L and/or IMAC standards including 1,2-DCA (0.4 ug/L), 2-methylnaphthalene (30 ug/L), benzene (1 ug/L), MTBE (20 ug/L); naphthalene (6 ug/L), and TBA (10 ug/L); • Two NCAC 2L exceedances of EDB (0.02 ug/L) were observed; and • No exceedances of NCAC 2L standards were observed for 1,2,4-trimethylbenzene (400 ug/L), 4-isopropyltoluene (25 ug/L), chloroform (70 ug/L), ethylbenzene (600 ug/L), methylene chloride (5 ug/L), toluene (600 ug/L), or total xylenes (500ug/L). Analytical data from the most recent groundwater sampling events conducted from 2015 through February 2024, suggests that the core of on-site groundwater impacts have remained stable or exhibited an overall decreasing trend. Based on the most recent comprehensive groundwater sampling event conducted in July 2023, data indicates that the dissolved-phase impacts to the shallow groundwater interval have been greatly reduced on the TEPRI property. Further, as is apparent in subsequent discussions of both mass flux and well cluster head evaluations, in most cases, the highest concentration of a given COC is not detected in the low head interval for the specific well cluster the sample was collected. This finding is nearly universal for on-site wells with the exception of monitoring wells MW-B-B and MW-H-B where the bedrock VOC impacts coincide with the low head interval for these two well clusters only. 3.1.11 Groundwater Sampling Results – Off-Site Wells The following section presents the water quality results from the July and December 2023 groundwater sampling events of the off-site monitoring network which consisted of 81 monitoring wells. As previously discussed in Section 1.7.1, a groundwater optimization analysis was approved by Guilford County in February 2022, and most on-site wells are only sampled on an annual basis. There are a select number of on-site wells sampled semi-annually. During this reporting period, the annual sampling event was completed in July 2023 and the semi-annual event in December 2023. Historical groundwater analytical results for all existing off-site wells are provided in Table 6. Analytical results of site-specific VOCs in the existing off-site wells during the July and December 2023 sampling events were observed as follows: • No VOC exceedances were observed in 30 off-site wells; • One or more of the site-specific VOCs exceeded the NCAC 2L and/or IMAC standards for 1,2,4-trimethlybenzene (400 ug/L), 1,2-DCA (0.4 ug/L), 2-methylnaphthalene (30 ug/L), benzene (1 ug/L), ethylbenzene (600 ug/L), MTBE (20 ug/L), naphthalene (6 ug/L), TBA (10 ug/L), and total xylenes (500 ug/L); • No NCAC 2L exceedances of EDB (0.02 ug/L) were observed; and Annual Monitoring Report Former Greensboro Terminal #1760 7115 West Market Street Greensboro, North Carolina 27409 • No exceedances of NCAC 2L standards were observed for 4-isopropyltoluene (25 ug/L), chloroform (70 ug/L), methylene chloride (5 ug/L), or toluene (600 ug/L). Analytical data from groundwater sampling events conducted from 2015 through 2023, suggests that the core of off-site groundwater impacts have overall remained stable or exhibited an overall decreasing trend. Further, as is apparent in subsequent discussions of both mass flux and well cluster head evaluations, in most cases, the highest concentration of a given COC is not detected in the low head interval for the specific well cluster the sample was collected. This finding is nearly universal for off-site wells with the exception of monitoring wells FMW-24, PMW-K-D, and PMW- L-D, PMW-N-I, where shallow, deep, and/or intermediate VOC impacts coincide with the low head interval for these well clusters. Overall, dissolved phase COCs are shrinking in their extent on-site and stable off-site. 3.1.12 Geochemical Trends A summary of the geochemical data collected at the site during the July 2023, December 2023 and February 2024 monitoring and sampling events is presented on Table 4. Field data collected and analyzed include DO, pH, temperature, specific conductivity, and ORP. The geochemical parameters change as groundwater moves into areas of the site where residual petroleum impacts exist. These parameters, when combined with analytical data for nitrate, manganese, ferrous iron, sulfate, and methane can be used to evaluate the predominant terminal electron acceptor species in supporting microbial activity to break down the contaminant plume. As microbes use available DO in the aquifer to metabolize the hydrocarbon plume, they will sequentially begin to use less thermodynamically favorable electron acceptors for respiration such as nitrate, manganese, ferric iron, sulfate, and finally methane. Figures 40 through 43 show the distribution of inorganic parameters that help define predominant terminal electron acceptor (TEA) species and when evaluated over time, can determine the effective monitored natural attenuation (MNA) process for each well for the July 2023 groundwater monitoring and sampling event, and gives an indication of aquifer conditions which are summarized below: • Aerobic – On-site monitoring well Z1-X27; Off-site monitoring well AMW-16S • Anaerobic Manganese/Iron Reducing – On-site monitoring wells Z1-X28 and Z4-X70; Off-site monitoring wells FMW-23R, FMW-24, AMW-18S, DEM-MW6R, and SBMW-1R • Anaerobic Iron Reducing – On-site monitoring well Z4-X89; Off-site monitoring well AMW-13S • Minimal COCs Reductive – Off-site monitoring well MW-B-B • Minimal COCs Oxidative – On-site monitoring well Z2-X20; Off-site monitoring well SBMW-2I Annual Monitoring Report Former Greensboro Terminal #1760 7115 West Market Street Greensboro, North Carolina 27409 *Underlined monitoring wells exhibit detections and/or exceedances of site-specific VOC’s. DO maps for shallow, intermediate, deep, and bedrock groundwater zones, to illustrate the most recent data collected during the July 2023 sampling event, are included as Figures 44 through 47, respectively. Generally, DO levels decline in the former source zones to < 1 mg/L and spatially correlate with the highest dissolved benzene concentrations. Aerobic bacteria will preferentially utilize oxygen as the electron acceptor when metabolizing benzene or other hydrocarbon compounds. When the available oxygen is depleted (DO drops below 1 mg/L), microbial colonies that utilize other terminal electron acceptors will drive the natural biodegradation process. In these cases, elements such as nitrate, sulfate, and ferric iron become electron acceptors. When the available supply of these is exhausted, fermentation begins to generate methane. The presence of detectable DO in all samples may also be attributed to the lengths of well screens being longer than the vertical dimensions of the micro-environments. ORP maps for shallow, intermediate, deep, and bedrock groundwater zones are provided as Figures 48 through 51, respectively, to illustrate data collected during the July 2023 sampling event. Background shallow groundwater exhibits strong positive values > 100 mv. In the source zones, the ORP levels become negative, correlating spatially with the lowered values of DO and higher benzene concentrations. Spatial variations in both DO and ORP levels are likely attributable to the lengths of well screens straddling small-scale microbial environments with different geochemical conditions. Taken together, the generalized patterns of DO and ORP still correlate with dissolved benzene concentrations in and near known source areas which are anoxic. Groundwater temperature maps for shallow, intermediate, deep, and bedrock groundwater zones, compiled from the July 2023 sampling event, are included as Figures 52 through 55, respectively. On-site, the highest groundwater temperatures are observed throughout Zones 3 and 4 and correlate with the most recent thermal remediation operations that ceased in October 2012. These data demonstrate the slow restoration of thermal equilibrium. Historically, all of the monitoring wells on the Greensboro site have supported ongoing anaerobic reductive degradation. As the overall concentration of COCs on-site has decreased, and currently many monitoring wells report no detected COC concentrations, the site conditions are slowly equilibrating back to a natural, pre-release state. This pre-release state of aerobic geochemical conditions is exemplified on-site by an increase in DO, ORP, nitrate, and sulfate concentrations, with a corresponding decrease in dissolved iron and manganese as these metals are oxygenated and precipitate out of solution. In monitoring wells where there are detections of organic COCs, the geochemistry continues to indicate anaerobic reductive degradation, exemplified by low or negative ORP, loss of nitrate, increasing manganese and/or ferrous iron, and in highly reductive areas, a loss of sulfur with or without methane production. Where there is no longer detectable COCs in an area, the previously anaerobic areas are switching back to aerobic conditions. This is noted by indicating the change in conditions in the monitoring well from anaerobic to aerobic (anaerobic/aerobic on the figures). Annual Monitoring Report Former Greensboro Terminal #1760 7115 West Market Street Greensboro, North Carolina 27409 Evaluation of these geochemical conditions over time indicates that many wells display conditions that could be interpreted as marginally aerobic or marginally anaerobic at sequential monitoring intervals or even at the same time. This suggests the groundwater system is both complex and tipping towards equilibrium conditions where petroleum hydrocarbon compounds are absent from the host of potential metabolic sources for indigenous microbial consortia. Where there is an absence of detectable COCs, this distinction may not be critical to understanding the MNA process for the site. However, it is evident from a number of lines of evidence, including long- term changes in geochemistry and comparison of COC mass flux from cross-gradient transects, that groundwater quality continues to demonstrate improvement relative to persistence and extent of dissolved phase COCs. Annual Monitoring Report Former Greensboro Terminal #1760 7115 West Market Street Greensboro, North Carolina 27409 4 Mass Flux Analysis 4.1 Mass Flux Background and Concepts It has long been recognized that contaminant transport through complex aquifer systems can be a challenge to understand and quantify. Numerous case studies have reported that as much as 90% of contaminant migration occurs through as little as 10% of the overall affected aquifer volume. This migration pattern is driven by the large range in hydraulic conductivity found throughout most aquifer systems. Contaminants can be “stored” in low conductivity or poorly interconnected aquifer media (moving primarily via diffusive chemical flow) and can migrate rapidly through high conductivity channels or zones (via adjective groundwater flow). This natural range of physical properties and resultant contaminant transport behavior has driven complex environmental contamination projects towards high-resolution site characterization (HRSC) techniques, which the USEPA, the ITRC, and others have espoused as best practices for complex site investigation and development of effective CSMs. ITRC published guidance on “Use and Measurement of Mass Flux and Mass Discharge” (ITRC, 2010) that offers several means to measure mass flux and incorporate the concepts and data into effective CSMs. Some of the benefits of employing mass flux concepts for site management as articulated in the ITRC guidance include: •“Mass flux is now being used more frequently to characterize and monitor groundwater contamination (USEPA 2003) due to a growing recognition that mass flux data can provide a more complete measure of the exposure posed by the contaminants than static point concentration estimates alone (Einarson and Mackay 2001; Buscheck, Nijhawan, and O’Reilly 2003).” •“Mass flux estimates can better characterize a contaminated site than typical monitoring networks (Feenstra, Cherry, and Parker 1996).” •“A mass flux calculation requires measurement of the variability in concentrations and velocities within a plane of the plume and therefore is based on a more thorough site characterization. Additionally, mass flux values at different times and places along a plume show the combined impact of all of the physical, chemical, and biological processes acting on the contaminants.” The site has undergone extensive remediation over the past 15-plus years: specifically, the 2007 to 2012 electrical resistive heating program. Thus, as a function of this source removal, it may not fit neatly into the “source-pathway-receptor” framework used by EPA and ITRC to embody the benefits of employing mass flux techniques. Nonetheless, given significant concentrations of residual MTBE and TBA compounds, application of mass flux concepts can offer improved understanding of subsurface contaminant behavior. This improved understanding in turn, should allow for more focused decision making and development of a remedial program aligned with site risk and contaminant transport attributes. Given the large number of existing groundwater monitoring wells at the site and good spatial delineation of dissolved-phase petroleum hydrocarbon compounds that exceed applicable concentration standards, a transect-based method was selected to evaluate and quantify Annual Monitoring Report Former Greensboro Terminal #1760 7115 West Market Street Greensboro, North Carolina 27409 contaminant mass flux across the site. This method provides the greatest data density and degree of confidence in the outcome. 4.2 Mass Flux Application 4.2.1 Geology and Contaminant Behavior Historical site investigation work (Arcadis, 2004) has shown the former Fina terminal and downgradient off-site PTIA property to be underlain by deeply weathered saprolite derived from the underlying Cambrian-aged, metamorphosed diorite of the Carolina Slate Belt (Piedmont Physiographic Province). Depths to competent, crystalline bedrock range from approximately 55 to 100 feet bgs across the site. Groundwater generally flows from south to north towards the PTIA property and thence to an unnamed tributary of Horsepen Creek. Depths to groundwater typically range from five to 25 feet bgs thereby indicating a thick saturated water table residing within the saprolite over the top of rock for the entire area. Historical in-situ thermal remediation was effective in the elimination of LNAPL (source) and related dissolved petroleum compound constituents in the groundwater system, however, follow- up groundwater quality investigations conducted both on-site and at the PTIA property indicated that several petroleum compounds can still be detected at concentrations above applicable IMAC and/or NCAC 2L standards. This finding, and a small number of high-concentration TBA detections in the bedrock aquifer prompted a 2015 re-evaluation of groundwater quality using a mass flux approach to better understand contaminant migration potential across the site. 4.2.2 Cluster Well Installation To accomplish this objective, a series of 18 additional well clusters comprised of shallow (water table), intermediate, deep, and bedrock wells were installed between 2015 and 2018. Half of these clusters were installed on the TEPRI property and half off-site on the PTIA property. In general, cluster well installation was completed as follows: 1. A deep boring was advanced via sonic drilling techniques to confidently identify the top of bedrock and provide quality soil cores for identification and description. 2. Borings were advanced into the bedrock aquifer a minimum depth of 15 feet or until evidence of some water production was noted. 3. A water table well, (denoted as “Shallow” in report figures and data tables), was installed if a shallow well did not already exist in close proximity to a corresponding deep well cluster. This was done for the furthest downgradient well clusters PMW-P, PMW-Q, and PMW-R only. The existing water table wells are generally screened from depths of five to 20 feet bgs. 4. An “Intermediate” saprolite zone well was installed - typically screened with 10-foot lengths in the 30 to 50 feet bgs depth range. Annual Monitoring Report Former Greensboro Terminal #1760 7115 West Market Street Greensboro, North Carolina 27409 5. A “Deep” saprolite zone well was installed such that the bottom of the well screen sits atop bedrock. These deep wells are typically completed with 10-foot screen intervals in the 50 to 90 feet bgs depth range. 6. A “Bedrock” zone well was installed – constructed with open-well completion from about 15 feet below the top of rock surface to a zone making water. Open intervals for the 18 bedrock wells range from 10 to 47 feet in length, average 15 feet in length and are found between 74 and 157 feet bgs. These 18 well clusters, in addition to three existing well clusters, were arranged into five linear transects aligned approximately perpendicular to established groundwater flow, as per ITRC guidance. These transects are identified as A-A’, B-B’, C-C’, D-D’, and E-E’ moving from south to north across the site. The wells comprising each transect are shown in the Mass Flux Transect Locations Map and are also identified explicitly in the Mass Flux Raw Data Table (Appendix A). Transect E-E’, located farthest downgradient and north of the PTIA retention pond, have either been non-detect for all dissolved petroleum compounds or have had minor and/or anomalous detections of 1,2,4-trimethylbenzene, EDB, chloroform, naphthalene, and/or toluene, below the NCAC 2L; therefore, no mass flux calculations were performed for those wells or along that transect. 4.3 Mass Flux Calculations and Groundwater Gradients The 2018 Annual Monitoring Report / Comprehensive Site Assessment Report (GES, May 2019), submitted to Guilford County and the NCDEQ, provides a detailed description of the cell set-up and calculations used to determine the mass flux for a given contaminant per transect cell. Groundwater gradients were determined for each of the four zones based upon well gauging data from July 2023. The horizontal groundwater elevation gradients in all four hydraulic zones show little difference, returning values of 0.015, 0.012, 0.013 and 0.013 feet/foot for the shallow, intermediate, deep and bedrock zones, respectively. The July 2023 groundwater analysis results were used to provide contaminant mass input for the flux calculations. Where a non-detect result was returned, half of the method detection limit was substituted to achieve a flux value. Cells highlighted in green on the Flux Calcs spreadsheets of Appendix A, indicate where this half- detection value technique was employed. The July 2023 groundwater analytical results are summarized in the mass flux tables in Appendix A and also on Tables 5 and 6. 4.4 Findings The Flux Calcs spreadsheets in Appendix A provide summaries of the input data and mass flux output for each of the 62 cells for the compounds TBA, MTBE, and 1,2-DCA, respectively. The estimated mass of each compound that moves through each of the four transects aligned perpendicular to groundwater flow is provided in the Appendix A worksheets and is summarized below for the July 2023 sampling event. The calculation outputs are expressed in grams per day (g/day) through each cell and further summed by transect. An interpretive summary of the findings is provided below by analyte.

However, most of these determinations were derived from non-detect lab results (31 of the 55). Further, less than half (26 of the 62 cells or 42%) yielded a TBA flux in excess of 0.1 g/day. The majority of TBA flux across the site (86% of the sum of all four transects) occurred through only 3 of the 62 cells which represent only 4.8% of the aggregate transect area. Of these three high flux zones, only one coincided with the low head feature for that well cluster – the on-site bedrock well B. • Flux from on-site sources (transects A-A’ & B-B’) are calculated at 292.2 and 350.6 g/day, respectively, indicating a remaining on-site source for TBA. These values are similar in magnitude to those calculated since this mass flux initiative was undertaken in December 2017 and suggest that the system is geochemically stable. • Transect E-E’ with 12 wells located north of the pond on PTIA property, returned all non- detect results for all constituents analyzed in groundwater samples, suggesting that Annual Monitoring Report Former Greensboro Terminal #1760 7115 West Market Street Greensboro, North Carolina 27409 complete compound degradation is realized within this area of the site. No flux calculations were undertaken for any of these 12 “clean” wells. • No significant change in TBA flux across the D-D’ transect is noted since Dec 2017; this value has ranged from 20.1 to 146.5 g/day, indicting MNA is capable of effectively mitigating the contaminant flux from residual source areas upgradient of the D-D’ transect area. • TBA flux across transect C-C’ is 971.7 g/day, of which 966.8 g/day (99%) occurs in the bedrock portion of the SBMW-2 cluster. Thus, one of 16 cells across transect C-C’ is responsible for nearly all of the net TBA transport across this integrated aquifer cross section. This SBMW-2 bedrock cell is not the low-head interval of that well cluster, further diminishing the potential for TBA transport out of the system from this location. • A TBA flux reduction of 86% is calculated from transect C-C’ to transect D-D’ on the PTIA property, consistent with previous calculations and indicative of intrinsic remediation effectiveness. • Overall TBA flux values and transect to transect relationships have remained relatively consistent across the site since December 2017 and do not demonstrate evidence of migration outside of the groundwater system defined by the local watershed. 4.4.2 MTBE • Some MTBE flux was measured in 22 of 62 cells total (35%). Only 1 of 62 cells demonstrated MTBE flux in excess of 0.1 g/day at 0.2007 g/day. • The observation of small MTBE flux values is partially associated with the amount of non- detect results obtained for MTBE (41 of 62 wells returned non-detect results). • The magnitude of MTBE flux is quite low across all transects with a system-wide total of only 0.40 g/day. Also, as noted, this “system-wide” total is not a true sum value as changes in MTBE concentration from transect to transect are clearly evident. • As was seen in prior years (but not in June 2022) with TBA, transect C-C’ yielded the highest flux across the aquifer flow field and a reduction of 82% was calculated from transect C-C’ to transect D-D’, again indicating some residual source beneath West Market Street as well as robust monitored natural attenuation activity downgradient of West Market Street. • Overall, MTBE flux does not appear to be a concern at this site and there is no evidence of MTBE migration outside of the groundwater system defined by the local watershed. 4.4.3 1,2-DCA • 19 of the 62 cells analyzed across all four transects (31%) yielded evidence of some detectable 1,2-DCA flux. No cells yielded a flux value in excess of 0.1 g/day. • The magnitude of 1,2-DCA flux is quite low across all transects with a total of only 0.034 g/day system-wide. • 11 of the total flux detections (58%) are deep or bedrock zones, and nearly half (5 of 11) align with low head flow zones. Similarly, 15 of the 19 total cells (79%) where some 1,2- DCA flux was calculated are located in the off-site transects C-C’ and D-D’. Annual Monitoring Report Former Greensboro Terminal #1760 7115 West Market Street Greensboro, North Carolina 27409 •Relative groundwater head relationships combined with 1,2-DCA mass flux results suggest that this compound may be from a regional source as detectable mass flux is calculated in the low-head interval in 5 of 16 well clusters, with all 5 in the off-site well clusters. •Measurable 1,2-DCA mass flux occurred in 13% of on-site cells and 50% of off-site cells. •1,2 DCA flux from the former TEPRI site equals 0.003 g/day across both the A-A’ and B- B’ transects combined. This value increased one order of magnitude for the C-C’ and D- D’ transects to 0.03 g/day, but still remains quite low and as noted above, detectable 1,2 DCA flux is found in 5 of 9 off-site low head zones – supporting the concept of a separate source and/or more regional presence. Overall, as noted previously, the source removal remediation performed from 2007-2012 on the TEPRI property has resulted in atypical source-pathway-receptor relationships for the site. From a mass flux standpoint, this has yielded low VOC flux values from on-site transects A-A’ and B-B’ and the greatest mass flux across transect C-C’ with a recognized decline in flux for TBA and MTBE from transects C-C’ to D-D’ indicative of robust natural degradation (monitored natural attenuation) processes. This is further supported by the fact that the entirety of transect E-E’ (12 discrete sampling locations in all four aquifer zones) have either been non-detect for all dissolved petroleum compounds or have had minor and/or anomalous detections of EDB, isobutylene, and/or toluene. Thus, all detectable contaminants passing through the D-D’ transect have been fully degraded or have by-passed the E-E’ transect wells. Further, there are no detections of any monitored compounds in surface water samples collected to date. 4.5 Groundwater Head Evaluation Evaluation of synoptic groundwater head data collected from all cluster wells in July 2023, suggests that the aggregate groundwater flow system at the Greensboro site behaves as an integrated continuum through the saprolite material and shows evidence of both downward flow and upward flow (regional groundwater discharge) through the bedrock aquifer. Also as described in Section 3.2.1, vertical gradients were evaluated for vertically adjacent well couplets according to the center-point to center-point method presented in EPA Region 4 modeling guidance. A total of 64 vertical gradient values were obtained from 22 well clusters (of which 20 contain a bedrock component) across the site. These data are summarized in Table 7. The calculated vertical gradients from cell to cell are primarily low, ranging from under 0.1% with only 8 of 64 values above 10%. Low head zones per well cluster were also identified using these July 2023 gauging data and are shown both in the mass flux calculations and mass flux cross sections in Appendix A. The mass flux data summary and calculations are presented in Appendix A. In addition to determining a mass value for selected compound migration through the defined cells and transects, this evaluation also considers groundwater head and resultant flow behavior from transect to transect. Vertical groundwater gradients are typically downward into the deep saprolite and bedrock zones on-site. The bedrock zone represents the low head component of six of nine on-site well clusters analyzed, but only three of 13 off-site clusters analyzed. Two of the 13 off- site well clusters do not have a bedrock well component. Upward flow from the bedrock aquifer Annual Monitoring Report Former Greensboro Terminal #1760 7115 West Market Street Greensboro, North Carolina 27409 is prevalent on the PTIA property where the deep saprolite zone represents the low head interval in seven of 13 well clusters analyzed. This finding fits with a regional groundwater flow model where discharge to surface water is likely to occur to the north at Horsepen Creek and is supported by a simple analysis of groundwater heads versus surface water elevations across the local site area. GES will continue to track relative head values for each hydraulic zone and the system as a whole. This will include collecting surface water elevations during monitoring events. The identification of mass flux combined with low head will better inform the site CSM and understanding of potential contaminant migration pathways. 4.6 Discussion This on-going evaluation of mass flux and discharge at the site continues to offer valuable insight into groundwater dynamics and contaminant fate and transport. By evaluating mass discharge at the site, and thereby accounting for the combined effects of concentration and groundwater velocity on contaminant movement, we have a more complete understanding of the site, which will inform decision making. This evaluation will continue for TBA as the primary COC; however, the mass flux values for MTBE and 1,2-DCA are very low and additional evaluation of mass flux for these contaminants provide little value in the overall CSM understanding. For example, contaminant concentrations alone cannot provide a complete picture of the processes governing plume behavior because groundwater velocity (which varies across a site) is an integral component of plume behavior. However, incorporating mass discharge and hydraulic head information into the CSM improves our understanding of plume behavior, identifies high-priority layers in dynamic aquifer systems, and provides a better analysis of natural attenuation rates (because transect data are less susceptible to temporal variations in flow direction and strength). Additionally, the results produced thus far point to both stability and natural attenuation of the selected dissolved organic compounds across the site as a whole and is further corroborated by both organic and inorganic chemical data over time. Mass flux and discharge estimates are valuable tools for contaminated site management. _____________________________________________________________ Annual Monitoring Report Former Greensboro Terminal #1760 7115 West Market Street Greensboro, North Carolina 27409 5 Discussion 5.1 Summary As outlined in Section 1.6 of this report, extensive remedial efforts were undertaken by TEPRI from January 1997 through October 2012. The goal of these source removal actions was to remove over 70% of the subsurface petroleum hydrocarbon mass such that the remaining residual mass would subsequently bioattenuate; this goal was achieved. These remedial efforts significantly reduced concentrations of COCs in groundwater both across the site, as well as at downgradient locations off-site. Additionally, LNAPL has not been detected in any on-site well since April 2013. There have been considerable reductions in dissolved benzene concentrations since ISTR was initiated in 2007 – in most cases contaminant concentrations decreased by at least three orders of magnitude in on-site wells and at least two orders of magnitude in off-site wells. Trends are less dramatic for TBA, as described below. TBA is typically derived from gasoline sources either as an oxygenate additive from 1979 to 2005, as an impurity in the additive MTBE, or as a breakdown product of the biodegradation of MTBE. MTBE has been historically detected at low to moderate levels in groundwater at the site – primarily prior to the in situ thermal remediation program undertaken by TEPRI. The presence of MTBE in groundwater is often associated with the presence of TBA. The source of TBA at MTBE-contaminated sites is difficult to identify. TBA has been shown in laboratory studies to be a product of MTBE biodegradation under both aerobic and anaerobic conditions. Studies have shown that MTBE can be transformed abiotically to TBA under methanogenic conditions. Research suggests that TBA can be generated by in-situ microbial breakdown of isobutene – another gasoline compound (API, 2012b). While MTBE is highly soluble in water, TBA is completely miscible and has a low affinity for gasoline. Therefore, minute amounts of TBA in the MTBE blended gasoline as an impurity can result in high aqueous TBA concentrations when MTBE oxygenated gasoline comes in contact with water. Thus, there are a number of potential sources and hydrocarbon breakdown mechanisms that can explain the presence of TBA – either as a primary or secondary (intermediate) product of a hydrocarbon release. Other potential sources of TBA from MTBE-containing gasoline (API, 2012b), include: • TBA as an oxygenate: Beginning in 1979 and into the early 1980’s, and in a small proportion of the gasoline supply, TBA itself was sometimes added to gasoline as an octane‐enhancer, with methanol as a cosolvent. • TBA in fuel grade ether oxygenates: As a byproduct of the manufacturing process, low concentrations of TBA (~2 wt%) were common in the “fuel grade” ether oxygenates such as MTBE. • TBA as a product of ether oxygenate biodegradation: TBA is well‐established as a product of MTBE biodegradation processes catalyzed by microorganisms in the environment. Annual Monitoring Report Former Greensboro Terminal #1760 7115 West Market Street Greensboro, North Carolina 27409 There are significant differences in the physical/chemical properties of MTBE and TBA. The loss of the more volatile VOC mass, including MTBE, results in the redistribution of the remaining mass between phases in the unsaturated zone, including an increased TBA mole fraction in any nonaqueous phase gasoline, an apparent enrichment of TBA mass due to increased aqueous TBA concentrations, and aqueous TBA/MTBE concentration ratios that increase with time. Thus, volatilization may play a role in, or dominate, TBA and MTBE concentration trends observed at spill sites with MTBE. Given its high volatility, MTBE is relatively quickly depleted from the system, reducing its concentration in the NAPL and pore water. In contrast, TBA is depleted very slowly, and therefore persists in the pore water (Eweis, 2007). The persistence of TBA relative to MTBE may explain the TBA concentrations being observed at the site. However, post-ISTR monitoring data for the site as a whole does point out reductions in dissolved MTBE ahead of TBA, suggesting that the MNA process is effectively reducing concentrations of both compounds and likely MTBE preferentially over TBA. Data collected thus far from the deep saprolite and bedrock aquifer zones suggest that the groundwater system at the site is vertically integrated through the saprolite zone (illustrated by minimal vertical gradients) but demonstrates higher head and upward vertical gradients in the bedrock zone, primarily in the off-site well clusters – possibly existing under confined or semi-confined conditions. Data and field observations collected thus far also demonstrate limited hydraulic capacity or conductivity in either the saprolite or bedrock aquifers. No evidence of high-yield or active flow zones in either setting was noted during geophysical investigations, well installation field observations or well development, purging, slug testing or sampling activities. The detection of elevated dissolved concentrations of certain COCs, particularly TBA, may be a function of limited groundwater flux and a reduced rate of natural biodegradation – the latter being a reasonable expectation following extensive heating of the subsurface where indigenous microbial populations would be largely sterilized. It is expected that re-establishment of microbial colonies would ensue after post-ISTR temperature equilibration and reintroduction of indigenous microbial communities through groundwater flux. Analytical data from semi-annual comprehensive groundwater monitoring and sampling events suggest the concentration of primary constituents of concern dissolved in groundwater is either decreasing or generally stable. The plume dimensions for some COCs (i.e., BTEX, MTBE, etc.) appears to be shrinking; and in the case of TBA, the larger plume shows an overall decrease in concentration compared with the 2015 and 2016 data. Additional data collected from surface water sampling at the off-site stream/pond interface, indicate the surface water is also integrated with the local, shallow groundwater system and is not impacted by any of the site-specific VOCs. 5.2 Conceptual Site Model During 2007 through 2012, aggressive thermal remediation in the former AST area removed significant quantities of LNAPL mass, reducing the primary source area for groundwater contaminants. The most recent LNAPL detection on-site was in April 2013. The remedial actions also significantly reduced the mass flux of COCs leaving the primary source area and moving off- site. Concentrations of the primary risk driver benzene in the source area, which previously exceeded 10,000 ug/L, reduced three to four orders of magnitude. The primary risk driver Annual Monitoring Report Former Greensboro Terminal #1760 7115 West Market Street Greensboro, North Carolina 27409 changed to TBA, having concentrations that were generally reduced in groundwater samples from the source area. The off-site area became the focus of investigations after 2012 when the updated CSM yielded data gaps related to groundwater flow patterns and potential COC migration to surface waters, along with the occasional LNAPL observations in the vicinity of the hydrocarbon interceptor wall. Further investigations to improve the CSM relative to off-site groundwater and LNAPL conditions were needed. Our current understanding is discussed below. 5.2.1 Groundwater Concentration Trends and Mass Flux Evaluation During this reporting period, two groundwater monitoring and sampling events were conducted at the site. Laboratory analytical results show concentrations of site-specific VOCs, including 1,2,4- trimethylbenzene, 1,2-dichloroethane, 2-methylnaphthalene, 4-isopropyltoluene, benzene, ethylbenzene, xylenes, MTBE, TBA, and naphthalene, which exceed the regulatory standard. Groundwater samples collected from the three most downgradient well clusters that were installed in December 2017 and comprise the E-E’ transect presented in Figures 30 and 37, have either been non-detect or have had minor and/or anomalous detections of 1,2,4-trimethylbenzene, EDB, chloroform, isobutylene, naphthalene, and/or toluene. On-site, TBA was detected above the IMAC standard in 16 out of 53 wells sampled, including detections in all four hydraulic zones. Dissolved TBA is adequately defined across the site especially given the identification of upward groundwater flow from the bedrock zone on the PTIA property. As noted in earlier analysis, there is strong evidence of robust and effective MNA activity that, coupled with upward hydraulic gradients, would likely preclude dissolved TBA migration beyond the local watershed. Benzene was detected mostly in the shallow wells and appears to be attenuating either by adsorption to soil particles or undergoing microbial degradation prior to downward groundwater migration (or both). Overall, benzene continued to show an overall stable or decreasing trend in comparison with historical data. In off-site wells, an overall stable trend of benzene and TBA was observed. Off-site, TBA was detected above the IMAC standard in all zones within the historical plume footprint. The mass of the TBA plume is centered on the on-site monitoring well MW-B cluster to near the monitoring well DEM-MW6 cluster off-site to the northeast. Downgradient, the TBA plume extends off-site to just beyond the barrier wall in the intermediate and deep wells in the MW-O cluster. The horizontal widening of the TBA plume as it moves off-site reflects the compound’s total miscibility in water and the complicated groundwater flow of the area. The high concentrations of benzene detected in wells FMW-23R, FMW-24, AMW-11S, AMW- 13S, and AMW-18S, suggest another source or a large section of the plume went untreated during the thermal remedial event. The area to the west of off-site well FMW-24, is delineated with the historical data from former well FMW-19 prior to its abandonment in December 2018. TBA is reasonably well delineated in the shallow zone with the possible exception of one area off- site near FMW-21 to the east. On-site in the intermediate, deep, and bedrock zones, TBA is delineated to the east and south, but not to the west. Off-site in the intermediate, deep, and Annual Monitoring Report Former Greensboro Terminal #1760 7115 West Market Street Greensboro, North Carolina 27409 bedrock zones, TBA is not delineated to the west and/or east; however, TBA is delineated to the north with the three new well clusters downgradient of the pond on the PTIA property. 5.2.2 Groundwater Flow Patterns The groundwater flow direction at the site throughout all hydraulic zones is generally in a northerly direction; however, slight fluctuations between the northwest and northeast have been observed since the December 2015 monitoring and sampling event. A localized groundwater mound and flow deflection exists around the barrier wall on the PTIA property. The interpreted flow directions and gradients from the gauging events are consistent with historical interpretations. Monitoring of water levels in wells completed to different depths in the saprolite and bedrock zones has provided data for inferring hydraulic gradients in three dimensions. While vertical gradients are more consistently downward in the saprolite zone of the former terminal area, they are consistently upward from the bedrock to saprolite zones off-site on the PTIA property. Incorporation of surface water head data support this regional flow model where some component of shallow groundwater will discharge to the pond and adjacent surface streams on the PTIA property and deeper groundwater may feed streams such as Horsepen Creek farther north. These same hydraulic relationships were referenced in previous CSM versions and flow models prepared for this site. 5.2.3 LNAPL Monitoring and Recoverability From May 2017 through April 2024, LNAPL in the vicinity of the barrier wall was monitored via quarterly gauging events of select monitoring wells and comprehensive groundwater monitoring and sampling events. These results are summarized in Section 3.1.1 of this report. During the gauging event on July 30, 2015, LNAPL was detected in FPZ-10 at a thickness of 0.17 feet. Prior to July 2015, LNAPL had not been detected since January 2008. During the December 6, 2023 gauging event, 0.07 feet of LNAPL was detected in monitoring well FPZ-10. During a follow-up field event on February 2, 2024, monitoring well FPZ-10 was gauged and no LNAPL was detected. Prior to the December 2023 event, LNAPL was not observed at the site since 2018. As previously stated, given the low transmissivity values, the LNAPL in the barrier wall wells is not considered recoverable and active LNAPL recovery is not believed to be a beneficial undertaking. Per the approved free product recovery strategy, passive recovery via absorbent socks installed in wells FPZ-10 and FPZ-15 was initiated in May 2016. Absorbent socks were replaced, as needed, during the routine events. Annual Monitoring Report Former Greensboro Terminal #1760 7115 West Market Street Greensboro, North Carolina 27409 6 Conclusions & Recommendations Given the large dissolved-phase plume and inherent geologic complexities at the site, the evaluation of mass flux and mass discharge has been adopted to assess contaminant fate and transport and manage risk. Mass flux is being measured using transects perpendicular to groundwater flow to assess contaminant discharge and plume attenuation rates and devise an appropriate long-term management strategy. Dissolved TBA occurs in groundwater at the site above applicable standards and monitored natural attenuation is likely to have a key role in the overall strategy for risk management. This approach to focus on groundwater quality and attendant mass flux conditions is appropriate given recent investigative findings whereby soil quality meets both NCDEQ Industrial/Commercial and Residential cleanup standards for all compounds analyzed site-wide. With the large number of existing groundwater monitoring wells at the site and good spatial delineation of dissolved-phase petroleum hydrocarbon compounds that exceed applicable concentration standards, a transect-based method was used to evaluate and quantify contaminant mass flux across the site. On-site transects (A-A’ and B-B’) yielded low flux values for MTBE and 1,2 DCA, but the highest TBA flux. The greatest mass flux for both TBA and MTBE is observed in the off-site transect just across West Market Street on the PTIA property (transect C-C’). A one order of magnitude increase in mass flux was calculated from the B-B’ to the C-C’ transects for MTBE and an increase of 177% was determined for TBA across this same area. A decline of flux of 86% and 82% is observed from transects C-C’ to D-D’ for the volatile compounds TBA and MTBE, respectively, indicating very effective monitored natural attenuation processes. This is also evident by the fact that the entirety of transect E-E’ (12 monitoring wells in all four aquifer zones installed in December 2017 and January 2018) has yielded non-detect results for all dissolved petroleum compounds or have had minor and/or anomalous detections of 1,2,4- trimethylbenzene, EDB, chloroform, isobutylene, naphthalene, and/or toluene. Thus, all detectable contaminants passing through the D-D’ transect have been fully degraded or have by- passed the E-E’ transect wells. The relative concentrations of 1,2 DCA appear to be driven by regional hydraulics as flux values are consistently low, but detectable in nearly all low head zones of all four transects analyzed. The mass flux evaluation offers exceptional insight into groundwater dynamics and contaminant fate and transport for the site. Evaluating mass discharge and thereby accounting for the combined effects of concentration and groundwater velocity on contaminant movement promotes a more complete understanding of the site. This approach, combined with a corresponding evaluation of relative hydraulic heads, will be continued to evaluate plume dynamics, potential contaminant transport avenues and natural attenuation. This evaluation will continue for TBA as the primary COC; however, the mass flux values for MTBE and 1,2-DCA are very low and additional evaluation of mass flux for these contaminants provide little value in the overall CSM understanding. Additionally, the results produced thus far point to stability of the selected dissolved organic compounds across the site as a whole. In keeping with this approach, RETIA proposes the following steps to define the near-term path forward for the site over the next year: Annual Monitoring Report Former Greensboro Terminal #1760 7115 West Market Street Greensboro, North Carolina 27409 • Continue to monitor liquid levels, on a quarterly basis, at the wells near the barrier wall located on the PTIA property to confirm that LNAPL has been fully remediated; • Continue to gather surface water elevations during groundwater monitoring events, to confirm no changes to groundwater-surface water interactions; • The current well network comprises 136 wells, of which 115 wells will continue to be sampled on an annual basis in June (per the approved Groundwater Monitoring Plan Optimization Analysis report. Additionally, 8 of these 115 wells will be sampled on a semi-annual basis in December. GES and RETIA will continue to evaluate the groundwater monitoring program and make recommendations to further reduce the network, eliminating wells that provide little value to the overall understanding of the CSM; • Eliminate MTBE and 1,2-DCA from future mass flux evaluations; • GES and RETIA are currently conducting an evaluation of the effectiveness of an EISB remedy at locations where mass flux calculations suggest there may be VOC transport. An EISB Evaluation Work Plan was submitted by GES on behalf of RETIA, to the NCDEQ and Guilford County on January 13, 2023 (later revised on January 25, 2023) to outline work to be completed. Data generated from the studies are used to directly support the presence of natural attenuation processes at the site and the ability to enhance the degradation with amendments. The data were collected in 2023 and are currently being evaluated to definitively determine if enhancement of the naturally occurring biodegradation process will significantly increase degradation of site contaminants. An EISB Evaluation Report will be submitted to the NCDEQ and Guilford County under a standalone cover; and • Continue to provide annual update reports to stakeholders including NCDEQ and Guilford County. The collection and evaluation of these additional data will continue to support formulation of a long-term risk management strategy for the site. The data indicate that MNA is an effective remedy for this site given the scope of historical remediation, current site attributes, in particular the lack of LNAPL, and potential receptors.

Therefore,plume extents represent conservative, simulatedconcentrations in areas not sampled in the specified timeperiod.3.Anomalous values at Z2-X34 in 2006 and 2008, Z2-X37 in2008, and at Z4-X01 in 2011 were not included in establishing the interpolated concentrations, but are presented for reference.4.Z4-X30, Z4-X68, and Z4-X72 overlap shallow andintermediate zones and were therefore excluded from interpolation analysis.5.Concentration grids represent interpolated data in ug/lfrom the following dates: 2006: May & June2008: February & March 2010: April & June2011: May, July, & September 2013: April2022: June 8814145515 [ [ [ [ [ [ [ [ [ [ [ [ [ [ [ [ [ [ [ [ [ [ [ [ [ [ [ [ [ [ [ [ [ [ [ [ [ [ [ [ [ [ [ [ [ [ [ [ [ [ [ [ [ [ [ [ [ [ [ [ [[ [ [ [ [ [ [ [ [ [ [ [ [ [ [ POTENTIALBURIEDMETAL OBJECT HYDROCARBONINTERCEPTORWALL AAACOOPER TPRI MAGELLANTERMINAL FORMERTANK FORMERTANK FORMERTANK FORMERTANK FORMERTANK FORMERTANK PIEDMONT-TRIADINTERNATIONALAIRPORT POND GRAVEL DRIVE TOP OF BANKTOP OF BANK TOP OF BANK TOP OF BANK TOP OF BANK ConocoPhillips ZONE 1 ZONE 2 ZONE 3 ZONE 4 Z4-X68 Z4-X72 Z4-X63 Z4-X35 Z4-X47 Z4-X21 Z4-X70 Z4-X30 Z4-X89 Z4-X60 &< &< &< &<&<&<&< &< &<&<&<&< &< &< &<&<&< &< &< &< &< &< &<&<&< &<&< &< &<&< &<&< &< &< &< &<&< &<&<&< &<&<&< &<&<&< &<&<&< &<&<&< &<&<&< &<&<&< &<&<&< &<&<&< &<&<&<&< &<&<&< &<&<&< &<&<&<&< &<&<&< &<&<&<&<&<&< &< &<&< &< &< &<&<&<&<&<&<&<&< &<&<&<&< &<&< &< &<&<&<&< % &< &<&<&< &< &< &<&< &< &<&<&< &<&< &<&< &< &< &< &<&< &< &<&< &< &< &<&< &<&< &< &< &< &< &<&<&<&< &< &< &< &< &< &< &< &< &< &< &< &< &<&<&< &< &< &< &< &< &< &< &< &<&< &< &< &< &<&< &< &< &< &< &< &< &< &< &< &<AMW-10S< 0.2 AMW-11S2.6 AMW-12S1 AMW-13S260 AMW-15S< 0.2 AMW-16S250 AMW-18S870 AMW-8S< 0.2 AMW-9S12 DEM-MW6R14 Z4-X631.2 FMW-15< 0.2 FMW-21< 0.2 FMW-22< 0.2 FMW-23R4.9 FMW-247100 FPZ-104.1 OW-4< 0.2 OW-8< 0.2 PMW-P-S< 0.2 PMW-Q-S< 0.2 PMW-R-S< 0.2 SBMW-1R38 SBMW-2R< 0.2 Z1-X270.82 J Z2-PZ-100.58 J Z2-PZ-0611 Z2-PZ-08< 0.2 Z2-PZ-09< 0.2 Z2-X200.57 J Z2-X29< 0.2 Z2-X310.41 J Z2-X35< 0.2 Z4-X30< 0.2 Z4-X478.2 Z4-X68< 0.2 Z4-X700.45 J Z4-X890.59 J AMW-14S< 0.2 Z3-X80< 0.2 Z4-X72< 0.2 Z1-X28< 0.2 Z2-X16< 0.2 Z3-X820.61 J Z4-X21< 0.2 Z4-X35< 0.2 100 100 1 1 1 1000100 10 1 Legend &<Monitoring Well, Sampled &<Monitoring Well %Stream Benzene Contour (ug/L) Interceptor Wall Property Boundary Pipeline Fence Former Feature Surface Water Remediation Zones [[ [Fence Line Parcels N:\Blacksburg\Projects\TPU\GreensboroNC\GIS\Greensboro_WG_AR_Benzene_Shallow_3Q2023.mxd - Scale 1:3,000 - 4/23/2024 1:55:25 PM - GStewart - NAD 1983 StatePlane North Carolina FIPS 3200 Feet Drawn 0 250 Scale In Feet (Approximate) 4/23/24 Groundwater Benzene Concentration MapShallow Wells - July 2023 Former Fina Bulk Fuel OilTerminal #1760Greensboro, North Carolina Designed Approved Figure16 GKS DMC DB Date Groundwater & Environmental Services, Inc.

When in doubt, use the Phish Alert Report button. Good morning Gene – Thanks very much for your response to my voicemail about the Former Greensboro Terminal #5067. Attached is a Site Map showing the two wells we proposed to abandon (highlighted yellow). I’ve also included a snippet from the Site Map showing those locations (see below). These two former recovery wells (RW-1 and RW-2) have been monitored since July 1997, since the installation of the barrier wall. Historically in RW-1, no product has been detected. In RW-2, product was only detected between November 1997 and January 2004. Additionally, these two wells have been sampled since October 2015 and all contaminants of concern have been non-detect. These former recovery wells no longer provide value to the long-term goals of the project. 11 Upon approval, we will abandon these two former recovery wells and provide notification once complete. If you need anything else at this time, please let me know.
