Peckham Lane Reno, NV 89502 SUBJECT: Annual Report for 2023 ABF Freight Terminal 55 South Redwood Road Salt Lake City, Utah Facility ID Number: 4001342 UST Release Site FFQ Dear Ms. Westover: The following document was prepared on behalf of the National Warehouse Investment Company to summarize activities associated with the ongoing remediation and annual groundwater monitoring at the ABF Freight Terminal Site located in Salt Lake City, Utah. INTRODUCTION A free product recovery (FPR) system was completed in January 2001 and has been operating for approximately 23 years. Groundwater and free product are being recovered from an extraction trench, treated through an oil/water separator, and then discharged into the sanitary sewer system under a discharge permit issued by the City of Salt Lake. In late 2009, a Xitech product recovery system was installed in the Shop Building of ABF. In January 2010, the free product recovery pump in well Ext-A began operation. The pump in Ext-B was installed in 2011. Extraction wells Ext-C and Ext-D were installed during February 2013. A pump was installed in Ext-D in May 2013. Wells Ext-A through Ext-D are located in the Shop Building of ABF (Figure 1). The free product from the recovery pumps is temporarily stored in a 55-gallon drum. Performance objectives for the FPR system as stated in the Corrective Action Plan Addendum (MWH, 2000) include the following:  Contain petroleum hydrocarbons on the site,  Remove free product, thereby eliminating the source of contaminants to groundwater, and  Reduce groundwater petroleum hydrocarbon contamination below State of Utah Division of Environmental Response and Remediation (DERR) criteria. Two of the three objectives are being achieved by the FPR system. The FPR extraction trench is located along the northwest property boundary to assist in plume containment. Although product recovery rates have declined over time, free product continues to be removed at the site by the FPR system. Along with plume containment, the FPR system assists in removing hydrocarbon contaminated groundwater where it can then be treated and discharged to the Salt Lake City Water Reclamation Plant under an Industrial Wastewater Discharge Permit for the ABF Freight Site. Data supporting the attainment of these system performance objectives are presented and discussed in this report. ABF 2023 Annual Report Page 2 ATLAS This report includes the following:  Summary of site activities during the period of January through December 2023,  Summary of free product measurements,  Laboratory reports for groundwater samples collected and analyzed during the annual groundwater monitoring event,  Summary of field data and historical groundwater sampling results,  System performance and petroleum hydrocarbon recovery data, and  Recommendations of actions to be completed within the next reporting period. SITE ACTIVITIES Monitoring Well Water Level and Product Thickness Measurements Weekly measurement of water levels and product thickness were conducted at 36 monitoring locations and in the trench sump throughout the 2023 annual reporting period. Water levels and product thickness were measured quarterly in 18 additional monitoring wells to provide an over- all picture of the groundwater hydraulics and product thicknesses across the site (Figures 2-9). Quarterly water level and measured product thickness data are tabulated in Appendix A. Monitoring well water levels were measured and then corrected to account for the effect of any overlying product layer. Graphs of corrected water levels and measured product thicknesses are included in Appendix A for selected wells used in the monitoring program. The water level and product thickness graphs include data collected from December 12, 1990, through December 27, 2023. An overall declining trend in groundwater levels persisted from 1998 through 2003 due to a regional drought. Although groundwater levels increased across the site throughout 2004 and through May 2005 as local precipitation increased, water levels decreased in the late summer and fall of 2005 and continued to decrease through 2006. Water levels increased from November 2006 to November 2008; then decreased from November 2008 to November 2009. Groundwater levels increased from November 2009 to November 2010; then decreased from November 2010 to November 2011. Water levels increased from November 2011 to November 2012. Water levels decreased an average of 0.61 feet between November 2012 and December 2013, and increased by an average of 0.23 feet between December 2013 and November 2014. Water levels decreased an average of 0.06 feet from November 2014 to November 2015; then increased an average of 0.02 feet between November 2015 and November 2016. Water levels decreased an average of 0.004 feet from November 2016 to November 2017 and 0.126 feet from November 2017 to December 2018. Water levels increased an average of 0.467 from December 2018 to December 2019, and then decreased an average of 1.17 feet between December 2019 and December 2020. Water levels increased an average of 0.25 feet between December 2021 and December 2022 and 0.16 feet between December 2022 and December 2023. Over the 2023 reporting period, water levels were highest in February. Quarterly groundwater elevation contours for February, June, September, and December, 2023 are illustrated in Figures 2 through 5, respectively. A distinct groundwater depression in the vicinity of the extraction trench is evident in all four figures, indicating for the most part that contaminated groundwater and overlying product currently on the site are hydraulically contained by the FPR system; although historical product measurements in monitoring wells W- 22 and HI-SW, indicate free product has been present off-site in the vicinity of these wells since installation of the FPR system in 2001. Historical product thickness data for selected wells used for the monitoring program are plotted in Appendix A. Monitoring well RW-E was ABF 2023 Annual Report Page 3 ATLAS decommissioned near the end of 2000. Monitoring wells W -8 and MW -5 were destroyed during soil excavation activities in November 2007 and replaced with HD-2, HD-3, and HD-4. Monitoring well W -2 was paved over in November 2008. Monitoring well W-7 was destroyed during soil excavation activities in September 2010 and replaced with HD-5 and HD-6. Monitoring well W -27A was installed on July 1, 2010, to replace W -27, which was destroyed during road work in the summer of 2007. Monitoring wells MW -C through MW -H were installed during February 2012, to further define the eastern-most boundary of the free product plume at the site. Monitoring well MW -A was destroyed during soil excavation activities in the Shop Building during October 2013 and replaced with wells Ext-E, Ext-F, and Ext-G. Wells W-1, EW- 5, and EW -6 were destroyed during soil excavation activities and replaced with MW -I and MW -J in November 2014. Well EW -18 was destroyed during the installation of the new Oil/Water separator in April 2016. Monitoring wells W-6 and W -17 were asphalted over in November 2017. W-18 was asphalted over during the summer of 2019. Wells EW-1, EW -2, EW-16, MW-C, and MW -D were destroyed during the soil excavation activities during October and November 2019 and replaced with MW -K, MW -L, MW -M, and MW-N. Well EW -11 was destroyed during soil excavation activities during September and October 2020 and replaced with MW -O. Product was observed consistently in 25 wells throughout 2023. Of these wells, the greatest product thickness was measured in MW -B, MW -E, MW -G, MW -N, EXT-B, EXT-C, and EXT-G. Figures 6 through 9 illustrate actual product thickness contours for February, June, September, and December, 2023, respectively. The data indicate that free product is the thickest in the Fueling Building and to the north and west of the Fueling Building. The product thickness in all of these wells is consistent with historical data. Well maintenance issues in W-9 (plugged well screen) had likely caused decreases in product thickness from 2004 through October 2005. This well was redeveloped in October 2005, and as a result, communication between the well and the aquifer increased substantially. A product thickness of 0.01 feet was measured in W-9 in December 2023. Free product from well W -9 is removed and the petroleum absorbent sock replaced during weekly operation and maintenance (O & M) activities. Since it was installed in February 2012, product has been consistently measured in MW -E. Free product levels in MW-E ranged from 0.02 to 1.84 feet during 2023. Product was measured in MW -H at a thickness of 0.10 feet on December 15, 2017. No product was measured in MW - H during 2018 through 2023. Free product was measured for the first time in MW -G in September 2020. Measurements in MW -G ranged from 0.00 to 1.09 feet during 2023. Product was removed periodically from the wells with product. No product has been measured in monitoring well MW -F since it was installed in February 2012. Since they were installed during soil excavation activities occurring from October 2006 through September 2010, product has been measured in HD-2, HD-3, HD-4, and HD-5. No product has been measured in the other two monitoring wells installed within the excavations: HD-1 and HD- 6. No free product was detected in HD-2 during 2014 through 2017. Product was detected in HD-2 at a thickness of 0.00 to 0.03 feet during 2023. Product in HD-3 was measured at a thickness of 0.00 to 0.07 feet during 2023. No free product was detected in HD-4 during 2014 or 2015. A trace of product was detected in HD-4 on November 17, 2016. During 2017, product was only detected once in HD-4 at a thickness of 0.02 feet on December 15, 2017. No free product was detected in HD-4 during 2018. Product was detected in HD-4 at a thickness of 0.00 to 0.22 feet during 2022. No product was detected in HD-4 during 2023. Product thickness in HD-5 ranged from 0.00 feet to 0.26 feet during 2018. No product was measured in HD-5 during 2019. Product was detected in 2020 and 2021 ranging from 0.00 to 0.17 feet. Product was detected in HD-5 in 2022 ranging from 0.01 feet to 0.21 feet, and 0.01 feet to 0.11 feet in 2023. The free product data indicated that the over-excavation activities have decreased product levels in the area directly west of the Shop Building (near HD-4). ABF 2023 Annual Report Page 4 ATLAS Monitoring wells MW -I and MW -J were installed during soil excavation activities in November 2014. Product thickness in MW -I ranged from 0.02 feet to 0.31 feet during 2023. Product thickness in MW -J ranged from 0.13 feet to 0.39 feet during 2023. MW -K, MW -L, MW -M, and MW -N were installed on March 5 and 6, 2020 to replace wells destroyed during over excavation during the fall of 2019. Free product in MW -K ranged from 0.01 to 0.22 feet during 2023. Product in MW -L ranged from 0.08 to 0.40 feet during 2023. Free product in MW-N ranged from 0.01 to 0.52 feet during 2023. No product was measured in MW - M since it was installed in 2020. MW -O was installed on November 17, 2020. No product was measured in MW -O from when it was installed through 2021. Free product was measured for the first time in MW -O in September 2022. Free product in MW -O was measured weekly during the remainder of 2022 and all of 2023. Free product in MW -O ranged from 0.13 to 0.42 feet during 2023. Free product had been detected in two of the perimeter monitoring wells north-northwest of the site (W -22 and HI-SW) since weekly measurements began on June 15, 2006 through 2016. Weekly data indicate no free product was detected in W-22 or HI-SW during 2017 through 2020. Free product was detected in MW -22 at a thickness of 0.14 feet on January 13, 2021. The free product was bailed from the well and a petroleum absorbent sock was placed in the well. Free product was not detected in MW -22 after January 13, 2021. No free product was detected in MW -22 during 2022 or 2023. Free product was not detected in HI-SW during 2023. Free product has not been detected in any of the other perimeter monitoring wells north or west of the site. Product Recovery Activities Throughout the 2023 reporting period, groundwater and free product were recovered from the FPR system extraction trench, the free product pumps in extraction wells Ext-A and Ext-D, as well as from selected monitoring wells and extraction wells. Product skimmed from the extraction trench sump and separated by the oil/water separator is conveyed to product storage tank where it is temporarily stored prior to off-site disposal. Product removed from Ext-A and Ext-D is stored in a 55-gallon drum located adjacent to the job-box. Free product is also removed manually with a peristaltic pump or with a bailer from select wells containing free product (wells W-9, EXT-G, and MW -N) during weekly O & M visits. Figure 10 shows the volume of product recovered throughout the history of the project. Approximately 273 gallons of product were removed during 2023. The total amount of product recovered in 2023 decreased by 104 gallons compared to the total amount of product recovered in 2022. The FPR system began operation in 2004. The following paragraphs discuss the removal history of the recovery system. The total amount of product recovered in 2004 was approximately three quarters of the amount of product recovered in 2003, the amount of product removed in 2003 was approximately half of what was removed in 2002, and the volume removed in 2002 was approximately one quarter of that removed during the first year of operation (2001). Free product recovery increased by 14% in 2005 and increased by 1% in 2006. There was a 23% decrease in free product recovery for 2007, a 20% decrease for 2008, a 39% decrease for 2009, a 52% increase for 2010, and a 32% decrease for 2011. There was a 283% increase of product recovered in 2012, at least partially due to free product being removed from additional wells during 2012. Free product recovered in 2013 increased by 13%. There was a 49% increase in free product recovered during 2014 compared to 2013. Free product recovery decreased by 57% in 2015 compared to 2014. There was an 81% increase in free product recovered during 2016 compared to 2015. Free product ABF 2023 Annual Report Page 5 ATLAS recovery decreased by 34% in 2017 compared to 2016. There was a 62% decrease in free product recovery in 2018 compared to 2017. Free product recovery increased by 102% in 2019 compared to 2018, mostly due to the amount of free product removed during the soil excavation activities in 2019. Free product recovery also increased in 2020. Free product recovery increased 225% from 2019 compared to 2020, but decreased by 61% from 2020 compared to 2021, mostly due to the amount of free product removed during soil excavation activities in 2020. Free product removal increased 6% in 2022 while decreasing by 32% in 2023. Decreasing recovery rates are a common characteristic of all subsurface product recovery systems regardless of the technology utilized. For the most part, free product has been removed in the immediate vicinity of the extraction trench at the ABF Freight site. Review of the data indicates that the thickest product pools appear to be relatively stable (refer to Figures 6-9). Overall, a cumulative total of approximately 22,651 gallons of free product has been recovered since the beginning of remediation activities in 1994. Product Disposal Recovered product is conveyed to a storage tank located inside of the FPR treatment system building. As the recovered product accumulates, it is periodically removed from the storage tank by Sump and Trap Cleaning, and disposed of at their facility located in Salt Lake City, Utah. On August 2, 2023, the product in the tank was removed, along with the sludge that was present in the sludge tank located inside the treatment system building. A copy of the waste manifests for the treatment system product are included in Appendix D. SUMMARY OF GROUNDWATER ANALYTICAL RESULTS The 2023 annual groundwater sampling and monitoring event was conducted on December 26- 28, 2023. Prior to well purging, the groundwater depth and free product thickness was measured in each well using an electronic oil-water probe. The probe was decontaminated between each well with an Alconox detergent wash and tap water rinse. The purge water and decontamination fluids were processed through the groundwater treatment system and discharge to the sanitary sewer. Following measurement of the depth to groundwater and free product thickness, monitoring wells MW -3, MW -7, MW -F, MW -H, MW -M, W -3, W-11, W-19, W-20, W-21, W -22, W-23, W -24, W-25, W-27A, EW -10, HD-1, HD-3, HD-4, HD-5, HD-6, HI-SW , RW -4, and RW -A were purged a minimum of three well casing volumes of water using a new factory sealed disposable PVC bailer from each well. After the purging process was completed, the wells were allowed to recharge for approximately one hour. Groundwater samples were then collected using the same bailer used to purge the well. The groundwater samples were transferred to appropriate sample containers, labeled, and stored on ice in an insulated cooler. The groundwater samples were then transported under chain-of-custody documentation to a Utah-certified laboratory for chemical analysis. Each sample was analyzed for methyl tert-butyl ether, benzene, toluene, ethyl benzene, total xylenes, naphthalene (MBTEXN) using USEPA Method 8260B Total petroleum hydrocarbons as diesel (TPH-diesel) and total petroleum hydrocarbons as gasoline (TPH-GRO) were analyzed using EPA Method 8015. The groundwater analytical data for December 2023 are presented in Table 1. Analytical results for BTEXN, TPH-GRO and TPH-diesel are also depicted in Figure 11, and the data validation documentation, laboratory report, and chain of custody are included in Appendix B. ABF 2023 Annual Report Page 6 ATLAS Concentrations of benzene were detected above the laboratory detection reporting limit in MW -7 (0.0110 mg/L). Toluene was detected in MW -H (0.00129 mg/L) and naphthalene was detected in MW -M (0.00773 mg/L). No other MBTEXN concentrations were detected above their method detection limit in any of the remaining wells sampled. No MBTEXN concentrations were detected above their respective Tier 1 screening levels. TPH-diesel was detected above the laboratory detection reporting limit in 22 of the 24 wells sampled during 2023. Eight of the wells had concentrations above the Tier I Screening Level of 10 mg/L: MW -H (22.800 mg/L), W-19 (28.500 mg/L), W -20 (16.300 mg/L), W-21 (39.400 mg/L), W-22 (15.200 mg/L), HD-3 (13.400 mg/L), HD-5 (51.700 mg/L), and HI-SW (12.900 mg/L). Concentrations of TPH-diesel decreased during the December 2023 monitoring event in wells MW -3, MW -7, MW -F, MW -H, MW -M, W-3, W-24, W-25, W-27A, HD-1, HD-4, HD-6, HI-SW, RW -A, and RW -4. while decreasing in the remaining comparable wells. Wells W-11, W-20, W- 21, HD-3, and HD-5 were not sampled in 2022.

The following quality assurance items were reviewed as part of the data verification and compared with acceptance criteria established by the analytical method:  Holding time  Flags  Field duplicate DATA VERIFICATION RESULTS Holding Time. All analyses were performed within the method specified holding times. Flags.  No Flags. Field Duplicate. A field duplicate sample, identified as MW -FD, was collected from MW -F to verify the laboratory's procedures and accuracy. The field duplicate was analyzed for BTEXN and TPH according to the standard operating procedures of the laboratory. Duplicate sample concentrations should be within the range of the sample concentration, plus or minus the control limit. If the sample value is less than 5 times the method detection limit (MDL), the control limit is plus or minus the MDL. If the sample value is greater than 5 times the MDL, the control limit is plus or minus 20% of the sample concentration. Comparison of duplicate sampling results from MW -F indicates that the duplicate control limit was met for all constituents. It should be noted that field QA/QC samples should not be the basis of accepting or rejecting data; rather, they should be used as additional evidence in support of the conclusions arrived at by a review of the total data package. Actions taken as a result of duplicate sample analysis must be weighed carefully since it may be difficult to determine if poor precision is a result of sample non-homogeneity, method defects, or laboratory technique. In general, the results of duplicate analysis should be used to support conclusions drawn about the quality of the data rather than as a basis for these conclusions.

This is not intended as a comprehensive explanation, and if you have additional questions please contact your project representative. Results Disclaimer - Information that may be provided by the customer, and contained within this report, include Permit Limits, Project Name, Sample ID, Sample Matrix, Sample Preservation, Field Blanks, Field Spikes, Field Duplicates, On-Site Data, Sampling Collection Dates/Times, and Sampling Location. Results relate to the accuracy of this information provided, and as the samples are received. Abbreviations and Definitions MDL Method Detection Limit. RDL Reported Detection Limit. Rec.Recovery. RPD Relative Percent Difference. SDG Sample Delivery Group. (S) Surrogate (Surrogate Standard) - Analytes added to every blank, sample, Laboratory Control Sample/Duplicate and Matrix Spike/Duplicate; used to evaluate analytical efficiency by measuring recovery. Surrogates are not expected to be detected in all environmental media. U Not detected at the Reporting Limit (or MDL where applicable). Analyte The name of the particular compound or analysis performed. Some Analyses and Methods will have multiple analytes reported. Dilution If the sample matrix contains an interfering material, the sample preparation volume or weight values differ from the standard, or if concentrations of analytes in the sample are higher than the highest limit of concentration that the laboratory can accurately report, the sample may be diluted for analysis. If a value different than 1 is used in this field, the result reported has already been corrected for this factor. Limits These are the target % recovery ranges or % difference value that the laboratory has historically determined as normal for the method and analyte being reported. Successful QC Sample analysis will target all analytes recovered or duplicated within these ranges. Original Sample The non-spiked sample in the prep batch used to determine the Relative Percent Difference (RPD) from a quality control sample. The Original Sample may not be included within the reported SDG. Qualifier This column provides a letter and/or number designation that corresponds to additional information concerning the result reported. If a Qualifier is present, a definition per Qualifier is provided within the Glossary and Definitions page and potentially a discussion of possible implications of the Qualifier in the Case Narrative if applicable. Result The actual analytical final result (corrected for any sample specific characteristics) reported for your sample. If there was no measurable result returned for a specific analyte, the result in this column may state “ND” (Not Detected) or “BDL” (Below Detectable Levels). The information in the results column should always be accompanied by either an MDL (Method Detection Limit) or RDL (Reporting Detection Limit) that defines the lowest value that the laboratory could detect or report for this analyte. Uncertainty (Radiochemistry)Confidence level of 2 sigma. Case Narrative (Cn) A brief discussion about the included sample results, including a discussion of any non-conformances to protocol observed either at sample receipt by the laboratory from the field or during the analytical process. If present, there will be a section in the Case Narrative to discuss the meaning of any data qualifiers used in the report. Quality Control Summary (Qc) This section of the report includes the results of the laboratory quality control analyses required by procedure or analytical methods to assist in evaluating the validity of the results reported for your samples. These analyses are not being performed on your samples typically, but on laboratory generated material. Sample Chain of Custody (Sc) This is the document created in the field when your samples were initially collected. This is used to verify the time and date of collection, the person collecting the samples, and the analyses that the laboratory is requested to perform. This chain of custody also documents all persons (excluding commercial shippers) that have had control or possession of the samples from the time of collection until delivery to the laboratory for analysis. Sample Results (Sr) This section of your report will provide the results of all testing performed on your samples. These results are provided by sample ID and are separated by the analyses performed on each sample. The header line of each analysis section for each sample will provide the name and method number for the analysis reported. Sample Summary (Ss)This section of the Analytical Report defines the specific analyses performed for each sample ID, including the dates and times of preparation and/or analysis. Qualifier Description J The identification of the analyte is acceptable; the reported value is an estimate. J1 Surrogate recovery limits have been exceeded; values are outside upper control limits. J7 Surrogate recovery cannot be used for control limit evaluation due to dilution. 1 Cp 2 Tc 3 Ss 4 Cn 5 Sr 6 Qc 7 Gl 8 Al 9 Sc ACCOUNT:PROJECT:SDG:DATE/TIME:PAGE: One Atlas L1692195 01/11/24 13:23 44
