INTRODUCTION On behalf of Mountain Crest Wasatch, LLC, the current property owner of the former Sommers Auto Wrecking property (Site) and the Volunteer, Wasatch Environmental, Inc., (Wasatch) has prepared this Remedial Action Plan (RAP) Implementation report that documents the remedial activities of heavy metals and petroleum hydrocarbon impacts to soil and groundwater at the Mountain Crest Wasatch, LLC., property (Site) located at 647 West 3300 South in South Salt Lake, Utah. All remedial activities at the Site were performed by Wasatch and our subcontractors in accordance with Wasatch’s general health and safety policy, RAP, Sampling and Analysis Plan (SAP), and Quality Analysis Project Plan (QAPP). A site-specific health and safety plan was prepared and implemented on-Site during all remedial activities to address specific health and safety concerns and establish protocols for conducting work -related activities in a safe manner. 1.1 Site Description The Site is located on the southeast corner of the 3300 South and 700 West intersection in South Salt Lake, Utah (as shown on Figure 1). The Site totals 5.15 acres and is comprised of two parcels (15-25- 351-034 and 15-26-477-006). The majority of the Site lies behind a vinyl and metal fence. The northern portion of the Site, outside of this fence, consists of a small asphalt-paved parking area, and a gravel-covered storage yard. The northeast portion of the Site is developed with an office building; two garage buildings; and a three-sided, metal, former dismantling building. On the western portion of the Site is a three-sided, metal, former oil storage building with a canopy-covered concrete secondary containment area. In the southwest corner of the Site, there is a metal canopy. The remainder of the Site consists of storage yard areas with concrete pads, pavement, and the majority of the area consisting of gravel. Property use at the Site and surrounding properties is a mix of commercial and light industrial. 1.2 Site Background The Site was formerly an auto wrecking yard previously occupied by Sommers Auto Wrecking. Currently, the Site is occupied by a landscaping company but will be occupied by a metals recycling facility in the near future. Our research indicates that the Site was residential and agricultural until 1956 when the former Sommer Auto Wrecking business started on the eastern portion of the Site. The wrecking yard expanded to the west between the 1960s and 1990s. In 2019, Sommers Auto Wrecking vacated the Site. Wasatch prepared an August 19, 2021, Phase I Environmental Site Assessment for the Site. During the completion of the Phase I Environmental Site Assessment, Wasatch identified the following recognized environmental conditions in connection with the Site: • In 2012, the Utah Division of Solid and Hazardous Waste (DSHW) recommended the removal of oil-impacted soil in the area of the dismantling building by the Site owner. Approximately 840 tons of impacted soil was removed and disposed off-Site. The excavation reportedly stopped at a clay layer approximately 4 feet below ground surface (bgs) and confirmation soil samples were not collected. No formal closeout documentation was created. Given that no confirmation soil samples were collected, there is a potential for residual impacts in this area. Remedial Action Plan Implementation Report Former Sommers Auto Wrecking Wasatch Environmental, Inc. Page 2 • Total petroleum hydrocarbons as gasoline-range organics (TPH-GRO) and oil and grease (O&G) impacts to soil and groundwater exceeding Utah Initial Screening Levels (ISLs) and/or Utah Risk - Based Corrective Action (RBCA) Tier 1 Screening Levels were identified by DSHW in 2012. • Low concentrations of tetrachloroethene (PCE) were detected in soil and water samples in two areas in 2012 indicating that PCE was either brought onto, or used at, the Site; therefore, there is a potential for elevated concentrations of PCE to be present in soil and groundwater in other areas of the Site. • Soil samples collected in 2012 were analyzed for Toxicity Characteristic Leaching Procedure (TCLP) metals, which is an analysis that measures leaching potential when evaluating soil disposal options. While the TCLP metals concentrations were below United States Environmental Protection Agency (U.S. EPA) landfill regulations, this analysis does not measure the concentration of contaminant of concern in a sample. Later in 2012, lead was detected in a waste characterization soil sample that was collected dur ing excavation activities at concentrations that exceeded U.S. EPA Residential and Commercial Regional Screening Levels (RSLs), indicating that elevated metals concentrations are likely present at the Site. • There was a drainage system and sump in the former oil storage building that was reportedly not working and has since been filled with concrete. There is a potential for impacts to the subsurface from this former drainage system. • Given the long-term use of the Site for auto wrecking and evidence of long-term poor housekeeping practices, there is a potential for impacts to the Site in areas that were not investigated in 2012. • There is a potential for impacts to the Site from releases associated with the long -term use of the east adjoining Pick-n-Pull property for auto wrecking. From 2021 through 2023, Wasatch completed three soil and groundwater sampling events that identified and characterized heavy metals and petroleum hydrocarbon impacts at the Site. During this time, Wasatch recommended that these impacts be reported to the Utah DEQ. The owner/operator of the Site reported the release to the Utah DEQ. As of July 22, 2022, the Site has been entered into the Utah Voluntary Cleanup Program (VCP) for regulatory oversight and has been assigned VCP Site #C122. The Utah VCP requested that additional Site characterization activities be completed at the Site, at the time of entry into the VCP, to facilitate the development of a RAP. The Site was sufficiently characterized and documented in the VCP-approved “Site Characterization Report – Revised” dated November 2023, which was completed by Wasatch (see this report for full details). Based on this report, lead and arsenic were detected in soils at concentrations that exceeded the U.S. EPA RSL for Industrial Soil, and petroleum hydrocarbons were detected in soil and groundwater at concentrations that exceeded their applicable Utah Initial Screening Level, U.S. EPA RSL for Industrial Soil, U.S. EPA MCL, and/or the calculated Site-Specific Cleanup Levels (SSCLs) calculated used the Utah DERR-approved DERR RBCA SSCL calculator. See Section 1.3 for additional details. Four impacted areas were identified by Wasatch and recommended for active remediation. Given the totality of the Site characterization data, Wasatch submitted a RAP to the VCP which was approved in a letter from the VCP dated January 30, 2024. In the RAP, an arsenic in soil cleanup goal of 45 mg/kg was requested by Wasatch and accepted by the VCP. Given the totality of the VOC and petroleum hydrocarbon data, it does not appear that these impacts are migrating off-Site. This is likely due to the clay lithology of the Site. See Figure 2 for the historical sample locations and Site features. Remedial Action Plan Implementation Report Former Sommers Auto Wrecking Wasatch Environmental, Inc. Page 3 1.3 Conceptual Site Model The Site is located within the discharge area for the principal basin-fill aquifer system. The discharge area of the basin-fill aquifer system is characterized by a shallow unconfined aquifer overlying a deep confined aquifer, with a confining layer (aquitard) separating the shallow unconfined aquifer from the deep confined aquifer. The discharge area typically exhibits an upward vertical hydraulic gradient. Soils at the Site generally consist of gravelly sand (SW/SP), gravel (GP), and clay (CL) fill materials ranging in thickness from 1 to 5 feet bgs. The fill is underlain primarily by clay (CL) and clayey sand (SC) with some silt (ML) and sand (SP). The dominant lithology of the Site is clay (CL). Based on previous borings and monitoring wells, depth to groundwater at the Site ranges from approximately 5 to 9 feet bgs. The hydraulic gradient is generally to the northwest. Soils consisting primarily of si lts and clays are potential contaminant storage zones. The majority of the metals impacts to soil was located within the surface soils or the upper 3 to 4 feet of soil at the Site, and the petroleum hydrocarbon impacts are typically located within the upper 6 feet of soil but extend down to 10 feet in localized areas. The southwest portion of the Site exhibited evidence of significant petroleum hydrocarbon contamination (exceeding U.S. EPA RSLs for Residential Soil and Industrial Soil) in shallow and deep soil indicative of a surface release(s) in this area. The distribution of these impacts was localized in the southwestern portion of the Site. Based on the groundwater samples collected by Wasatch, groundwater samples GP -14, GP-15, GP-16, GP-22, GP-23, and GP-23 exhibited petroleum hydrocarbon impacts (including benzene, ethylbenzene, and xylenes) concentrations that exceeded the applicable U.S. EPA MCL or Utah ISLs. All soil samples collected by Wasatch for metals analysis exhibited arsenic concentrations in soil that exceeded the U.S. EPA RSL for Residential and Industrial Soil. The detected arsenic concentrations in soil has been properly characterized and do not require active remediation except as discussed below and in Section 1.6. Wasatch soil samples GP-9 (2’-3’) and GP-11 (3’-4’) exhibited lead (1,270 mg/kg and 5,390 mg/kg) and arsenic (109 mg/kg and 141 mg/kg) concentrations in soil that exceeded the U.S. EPA RSLs for both Residential and Industrial Soil. No soil samples were collected below these samples; however, these impacts are located in an area of former battery storage as part of the former automotive wrecking activities at the Site. It has been Wasatch’s experience that heavy metal impacts from battery storage typically do not extend below 5 feet bgs and typically do not significantly spread laterally from the footprint of the battery storage area. No other metals were detected at concentrations exceeding applicable U.S. EPA RSLs for Industrial Soil in these samples. Wasatch soil sample DU-2E exhibited a lead (1,270 mg/kg) concentration that exceeded the U.S. EPA RSLs for both Residential and Industrial Soil. No other surface soil samples exhibited heavy metals concentrations that exceed the U.S. EPA RSLs for Industrial Soil (except for arsenic, see Section 1.6 for further details) No other heavy metals impacts were detected in soil samples collected by Wasatch at concentrations that exceeded their applicable U.S. EPA RSLs for Industrial Soil. Based on the totality of the arsenic in groundwater data, the concentration range of arsenic -impacted groundwater entering the Site (highest concentration entering the Site is located at the southeast corner) is approximately equal to the arsenic impacted groundwater hydraulically downgradient of the Site. Only one arsenic hot spot in groundwater was identified within the petroleum release area located on the southwestern corner of the Site. It is our opinion that the release of pe troleum hydrocarbons in this area has likely increased the leachability of arsenic for this area resulting in elevated arsenic concentrations in Remedial Action Plan Implementation Report Former Sommers Auto Wrecking Wasatch Environmental, Inc. Page 4 groundwater. This area was excavated during the active remediation activities which should result in the reduction of arsenic in groundwater to concentration ranges entering the Site. Based on the groundwater samples collected by Wasatch, no other metals were detected at concentrations that exceeded their applicable U.S. EPA MCL. Given the Site will be using a municipal water supply and not the shallow groundwater, this exposure pathway for metals is considered to be incomplete. Therefore, Wasatch plans to mitigate these impacts and potential exposure risks through the use of institutional controls. The source areas have been identified at the Site. See Figure 3 for source area locations. 1.4 Objectives Mountain Crest Wasatch, LLC, plans to redevelop the Site mainly for use as an industrial metal recycling facility. Therefore, the objective of this remedial action was to remediate soil and groundwater at the Site to meet the U.S. EPA RSLs for Industrial Soil (not including arsenic) and U.S. EPA MCLs for groundwater or to site-specific fractionation risk thresholds. Given that the Site will be using a municipal water supply and not the shallow groundwater, this exposure pathway is considered to be incomplete and exposure risks to the arsenic in groundwater impacts will be mitigated using institutional controls described below . 1.5 Contaminants of Concern Contaminants of concern at the Site are arsenic, lead, benzene, toluene, ethylbenzene, xylenes, naphthalene (BTEXN), TPH-GRO, total petroleum hydrocarbons as diesel-range organics (TPH-DRO), and total recoverable petroleum hydrocarbons (TRPH)/O&G. 1.6 Cleanup Goals For arsenic in soil, a cleanup goal of 45 mg/kg was approved by the VCP. The cleanup goals for soil at the Site are the U.S. EPA RSLs for Industrial Soil (except for arsenic as discussed above) or for TPH-GRO, TRPH, O&G, and TPH-DRO site-specific fractionation risk-based cleanup goals (calculated using the DERR-approved DERR RBCA SSCL calculator using post remediation exposure risk potential, see Appendix A) for the following exposure pathways: surface soil ingestion and subsurface soil ambient air vapor inhalation. The site-specific fractionation risk for subsurface soil indoor air vapor inhalation will also be evaluated, but is not considered a remediation goal, as if this threshold is exceeded this exposure will be mitigated using engineering controls. Remediation of soil to this standard is protective of composite workers and construction workers with respect to the soil ingestion and inhalation exposure pathways. No active remediation was proposed for the arsenic impacts to groundwater; however, it is Wasatch’s opinion that the active remediation proposed for the petroleum hydrocarbons will likely reduce the arsenic in groundwater concentrations within that area to concentrations ranges en tering the Site. Groundwater at the Site would be remediated to meet the U.S. EPA MCLs (except for arsenic as discussed above) or site-specific fractionation risk-based goals for the groundwater outdoor air vapor inhalation pathway. The site-specific fractionation risk for groundwater indoor air vapor inhalation pathway would be evaluated, but would not be considered a remediation goal, as if this threshold is exceeded this exposure would be mitigated using engineering controls. Groundwater is not used at the Site; therefore, the ingestion of groundwater exposure is not complete and this exposure would be mitigated using engineering or institutional controls. Residual risk to on-Site receptors will be managed through the use of engineering and institutional controls (discussed in Section 1.8 below), and Wasatch will coordinate to obtain VCP approval of the required environmental covenant and site management plan under a separate cover. Remedial Action Plan Implementation Report Former Sommers Auto Wrecking Wasatch Environmental, Inc. Page 5 1.7 Remedial Action Measures Given the Site characteristics, nature and distribution of contaminants, and proposed future land use; Wasatch selected over-excavation and off-Site disposal of the impacted soil within the source areas. Additionally, petroleum-impacted groundwater was extracted from the petroleum soil excavation (EXC-4), then treated on-Site and properly discharged under permit to the stormwater sewer. Details regarding the remedial action measures are provided in Section 3 of this report. 1.8 Proposed Engineering and Institutional Controls The following engineering and institutional controls are proposed to manage residual exposure risks post remedial actions. 1.8.1 Environmental Covenant (EC) and Site Management Plan (SMP) Wasatch and the Volunteer understand that a SMP and EC would be required to facilitate regulatory closure of the release. Institutional controls (i.e., an EC and/or SMP, etc.) and engineering controls will be implemented as needed to reduce the probability of exposure to the contaminated soil and/or groundwater by restricting how the Site may be used (i.e., forbidding the extraction and use of shallow groundwater, providing directions for managing impacted groundwater in the future [groundwater monitoring, obtaining groundwater dewatering permits if needed], etc.). This would be protective of Site occupants and could facilita te regulatory closure of the release at the Site with residual soil and/or groundwater contamination left in place on -Site. The EC and SMP would be subject to review and approval by the Utah Division of Environmental Response and Remediation (DERR). Engineering and institutional controls would be protective of Site occupants. At a minimum, these documents would restrict property use to non-residential use (without further remedial activities and additional sampling to verify this property use is safe) in contact with the ground surface and prohibit the extraction and use of shallow groundwater. The specific wording of these restrictions, the need for engineering controls (i.e., vapor barriers, etc.), and the potential need for long-term monitoring requirements (i.e., groundwater monitoring, etc. [if required]), would be based on the outcome of the remedial action effort as indicated by laboratory analytical results from the soil and groundwater confirmation sampling. 2. PERMITTING AND NOTIFICATION REQUIREMENTS 2.1 Blue Stake Utility Clearance Wasatch submitted a utility clearance request (Ticket Number C41210893-00C) to Blue Stake Utility Notification Center on July 30, 2024, prior to the excavation work. The Blue Stake Ticket Number was communicated via email to the contractors on the same date so that they could duplicate the request. A copy of the email confirmation sent from Blue Stake of Utah is presented in Appendix B. 2.2 Soult Salt Lake Permit Wasatch submitted an “Engineering Application” to the South Salt Lake Engineering Department to facilitate the on-Site excavation activities. The permit was approved and issued by Soult Salt Lake on August 1, 2024. Documentation related to this permit is presented in Appendix C. 2.3 Utah Division of Water Quality (UDWQ) Treated Groundwater Discharge Permit Wasatch submitted an “UPDES [Utah Pollutant Discharge Elimination System] general Permit for Treated Groundwater and Surface Water” notice of intent to the UDWQ on June 24, 2024, to facilitate the treatment and disposal of petroleum-impacted groundwater from the EXC-4 excavation. The UDWQ Remedial Action Plan Implementation Report Former Sommers Auto Wrecking Wasatch Environmental, Inc. Page 6 approved the permit by email on July 16, 2024, and assigned the Site permit number UTG7901107. On September 27, 2024, following completion of the treatment and groundwater discharge (which was completed as a single batch discharge), Wasatch submitted a “Notice of Termination” (NOT) form to terminate the permit. Documentation related to this permit is presented in Appendix D. 2.4 Notification to Salt Lake County Health Department Wasatch notified the office of Dorothy Adams, the Salt Lake County Health Department Director, of the pending remedial action by telephone on July 30, 2024. The telecommunication was documented on a Wasatch telecom form. The notification stated that the remedial action would commence on approximately August 5, 2024. A copy of the telecom form is presented in Appendix E. 2.5 Public Notice On December 15, 2023, Wasatch distributed written notices to the occupants of the neighboring businesses notifying them of the pending remedial action and advising them of the schedule for the corrective action. A copy of the written notice is presented in Appendix F. 3. REMEDIAL ACTION METHODS The following sections of this report present the methods and results of the remedial activities conducted in connection with the documented petroleum hydrocarbon and metals impacts at the Site. All remedial action activities were performed by the Volunteers subcontractors and by Wasatch and our subcontractors in accordance with Wasatch’s general health and safety policy. The health and safety plan was on-Site at all times during the remedial activities. Daily health and safety tailgate meetings were conducted by Wasatch during the corrective action. See Appendix G for a photographic log of field remedial activities. 3.1 VCP-Requested Sampling Given that TRPH and O&G concentrations from surface soil sample DU-1 and a TPH-DRO concentration from surface soil sample DU-2 exceeded Utah ISLs during the previous 2023 investigation, the VCP requested that a second sample be collected from each of these DUs to further evaluate the risks associated with these impacts. On June 17, 2024, Wasatch collected one 20-point composite surface soil sample from each of these DUs. Each aliquot location was randomly selected to provide sufficient spatial distribution. The samples were designated “DU-1” and “DU-2” to correspond to the DUs shown on Figures 2 and 3. Additionally, a duplicate sample of DU-1 was collected and designated DU-10. Each aliquot for the 20-point composite soil samples was collected using gloved hands and a clean 2 - ounce glass jar. A new 2-ounce glass jar was used for each individual DU. Each aliquot consisted of 2 ounces of soil, which was placed inside a plastic Ziploc ® bag and homogenized for a minimum of 5 minutes prior to dispensing the soil into the laboratory-supplied sample containers. The sample containers were each labeled with the sample location, sample identification, date, required analysis, and time of sample collection. All composite soil samples were placed on ice in a sample cooler. The coolers containing the soil samples were hand delivered, under chain-of-custody protocol to Chemtech-Ford Laboratory (CF), a Utah-certified analytical laboratory, for analysis. These samples were analyzed for TPH fractionation using U.S. EPA Method 8270E to further evaluate the risks associated with these impacts. 3.2 Test Pit Sampling Prior to commencing remedial activities at the Site, Wasatch submitted utility clearance requests to Blue Stake Utility Notification Center on June 12, 2024, and July 30, 2024. Remedial Action Plan Implementation Report Former Sommers Auto Wrecking Wasatch Environmental, Inc. Page 7 On June 17, 2024, a total of six test pits (designated TP-1 through TP-6) were completed at the Site that facilitated the collection and analysis of soil samples. The test pits were excavated using a mini excavator operated by Direct Push Services (DPS), the subcontractor. The test pits were completed in the vicinity of the proposed petroleum-impacted soil excavation (EXC-4) in an effort to better define the lateral extent of petroleum impacts to soil and to potentially reduce the area of active remediation. See Figure 3 for test pit soil sample locations. Soil excavated from the test pits was screened in the field using a photoionization detector (PID) equipped with a 10.6 electron volt lamp. The PID was calibrated with a 100-parts per million (ppm) isobutylene standard calibration gas. The PID is utilized to identify soils which may have been impacted by volatile organic compounds (VOCs) such as those found in petroleum fuels and some solvents. One soil sample was collected from each test pit location at the depth interval exhibiting the most significant indications of contamination based on field screening and field observations (e.g., elevated PID readings, soil staining, and petroleum or solvent odors). However, soil samples collected from test pit locations that coincide with previous sample locations were collected at that same depth interval. The soil samples were collected using gloved hands and dispensed into appropriate laboratory- supplied/prepared containers and immediately placed in iced coolers. Soil samples collected for TPH- GRO fractionation analysis were collected following the U.S. EPA Method 5035A sampling procedure. Soil samples collected for TPH-DRO fractionation were collected into 4-ounce glass jars. Each sample was labeled with date of collection, sample time, sample identification, and requested analysis. The soil samples were submitted under chain-of-custody protocol CF for analysis. The soil samples were analyzed for TPH-GRO fractionation using U.S. EPA Method 8260D and TPH-DRO fractionation using U.S. EPA Method 8270E. Following completion of the test pit soil sampling activities, the test pits were backfilled and compacted with clean imported fill material. 3.3 Impacted Soil Excavation and Off-Site Disposal Remedial activities at the Site were performed by Wasatch Senior Field Geologist Jake Scott; P.G., between August 6, 2024, and September 20, 2024. Remedial activities involved the completion of one shallow impacted area excavation (EXC-1) and the completion of three deep impacted area excavations (EXC-2, EXC-3, and EXC-4). See Figure 3 for excavation locations and boundaries. 3.3.1 EXC-1, EXC-2, and EXC-3 Excavations EXC-1 was completed along a portion of the northeastern boundary of the Site, where lead impacts to shallow soil were identified. EXC-2 was completed in the vicinity of soil boring GP-9, where deep lead and arsenic soil impacts were identified. EXC-3 was completed in the vicinity of soil boring GP-11, where deep lead and arsenic to soil impacts were identified. Excavations EXC-1, EXC-2, and EXC-3 were guided based upon field screening using a handheld X-ray fluorescence (XRF) analyzer. The XRF analyzer is utilized to identify the presence of a wide range of elements in the soil, namely heavy metals. Impacted soil for each excavation was directly loaded into haul trucks using an excavator and then transported to IRL for disposal. Each load was documented with a non-hazardous waste manifested by Wasatch. The excavations continued until there were little to no remaining indications of lead and arsenic impacts (i.e., no staining, no odors, or elevated XRF readings). Soil under the on-Site buildings was not excavated as the buildings are not planned for demolition. A large area of the planned EXC-1 area was covered with concrete pavement. The concrete pavement was excavated and disposed of off -Site and the soil beneath the concrete was screened with an XRF and sampled as a composite surface soil sample (EXC -1-Comp) to determine if this soil required excavation and off-Site disposal. Based on the soil XRF screening and the composite soil sample, Wasatch determined the area under the former concrete Remedial Action Plan Implementation Report Former Sommers Auto Wrecking Wasatch Environmental, Inc. Page 8 pavement did not require remediation. The remainder of the area within the EXC -1 boundary was excavated to approximately 0.5 feet bgs. The Volunteer provided their own in-house Occupational Safety and Health Administration (OSHA)-certified excavator and transportation subcontractors. 3.3.2 EXC-4 Excavation EXC-4 was completed on the southwestern corner of the Site where petroleum hydrocarbon impacts were identified. Excavation EXC-4 was guided based upon past data, test pit data, soil confirmation data, field observations of grey to black staining and petroleum hydrocarbon odors, as well as field screening using a photoionization detector (PID) equipped with a 10.6 electron volt lamp. Impacted soil for each excavation was directly loaded into haul trucks using an excavator and then transported to IRL for disposal. Each load was documented with a non-hazardous waste manifested by Wasatch. The excavations continued until there were little to no remaining indications of petroleum hydrocarbon impacts (i.e., no staining, no petroleum odors, or elevated PID readings). 3.4 Extraction, Treatment, and Disposal of Petroleum-Impacted Groundwater Groundwater was encountered at approximately 6 to 7 feet bgs during the excavation activities in excavation EXC-4. The groundwater was petroleum-impacted as evident by a strong hydrocarbon odors, observed sheens, and observed free product on the water surface. During the excavation activities, sorbent pads were placed in the excavation pit to soak up and remove as much free product as possible. Once the observed free product appeared to be removed from the water within EXC-4, the absorbent materials were collected and placed within a 55-gallon drum for disposal. This drum was picked up by Safety Kleen and disposed at the Clean Harbors Grassy Mountain facility. Petroleum-impacted groundwater was removed from the EXC-4 excavation pit using a trash pump and a 2-inch diameter water hose, which was then discharged into two separate 21,000-gallon holding tanks located on-Site. An aeration system constructed of 1-inch diameter PVC was installed within each holding tank. Both aeration systems were continuously operated during the dewatering process using a gas-powered air compressor to aerate and remove VOCs. Once the holding tanks were near full capacity, the water was then discharged through a bag filter and granular activated carbon vessel, and was then discharged to the storm sewer located off-Site just southwest of EXC-4. Prior to discharging the water from the holding tanks into the storm sewer, water samples (designated “Fack Tank 1” and Frac Tank 2”) were collected from the discharge hose of the granular activated carbon vessel to verify the treated groundwater water met the UDWQ permit discharge requirements. The treated groundwater was discharged as a single batch discharge event. 3.5 Soil Confirmation Sampling Following the completion of each excavation, soil confirmation samples were collected from the floors and side walls to establish that cleanup levels had been met. The sample locations were spaced at intervals to provide sufficient coverage of the entire excavation and not allow more than 50 linear feet of sidewall and no more than 2,000 square feet of floor to go unsampled. See Figure 3 for soil confirmation sample locations. Soil confirmation samples collected for analysis of methyl tertiary-butyl ether, benzene, toluene, ethylbenzene, xylenes, and naphthalene (MBTEXN), and TPH-GRO were collected using a laboratory- supplied sampling device, sample preservation methods, and sample containers consistent with U.S. EPA Method 5035A for the collection of VOCs. Soil confirmation samples were collected from each sample interval for both low-range (0.5 to 250 micrograms per kilogram [µg/kg]) and high-range (>250 Remedial Action Plan Implementation Report Former Sommers Auto Wrecking Wasatch Environmental, Inc. Page 9 µg/kg) laboratory analysis for VOCs. Low-range soil samples were collected as 5-gram (g) aliquots and placed in laboratory-supplied, unpreserved volatile organic analysis (VOA) bottles. High-range samples were collected as 10g aliquots and placed in laboratory-supplied VOA bottles preserved with methanol. Soil confirmation samples collected for analysis of TPH -DRO, lead, and arsenic were dispensed into laboratory-supplied 4-ounce glass jars. The confirmation soil samples were collected using gloved hands. The vials and jars were each labeled with the sample location, sample identification, date, time of sample collection, and requested analysis. The soil confirmation samples were placed in a cooler with ice and transported under chain -of-custody protocol to CF for analysis. The soil confirmation samples collected from EXC-1 were analyzed for lead using U.S. EPA Method 6020A. The soil confirmation samples collected from EXC-2 and EXC-3 were analyzed for lead and arsenic using U.S EPA Method 6020A. The soil confirmation samples collected from EXC-4 were analyzed for MBTEXN and TPH-GRO using U.S. EPA Method 8260D and TPH-DRO using U.S. EPA Method 8015D with silica get treatment (SGT). To expedite the process, laboratory analysis was performed on a 24-hour turnaround time. Additionally, selected soil confirmation samples collected from EXC-4 were also analyzed for TPH-GRO fractionation using U.S. EPA Method 8260D and TPH-DRO fractionation using U.S. EPA Method 8270E. After completion of the excavations, and receipt of the confirmation sample analytical results confirming cleanup goals had been met or additional excavation was not possible due to the presence of underground utilities, the excavations were backfilled and compacted with clean imported fill material. 3.6 Groundwater Confirmation Sampling Following completion of the dewatering activities, a total of two groundwater confirmation samples (designated “EXC-4-GW1” and “EXC-4-GW2”) were collected from the upgradient and downgradient portion of the open excavation pit to verify that cleanup levels for groundwater had been met. See Figure 3 for excavation confirmation groundwater sample locations. Groundwater confirmation samples collected from the open excavation were collected using gloved hands and a Teflon dipper. The groundwater confirmation samples were then dispensed into 40-milliliter (mL) capacity glass vials with Teflon® septa caps. The vials, which were supplied by the analytical laboratory contained several drops of hydrochloric acid as a preservative. The vials were filled slowly until a meniscus formed at the top of each vial, then each vial was sealed with a septa cap. This procedure eliminates headspace within the vials and minimizes the loss of volatiles. The sample containers were each labeled with the sample location, sample identification, date and time of sample collection, and requested analysis. The groundwater confirmation samples were placed in an iced cooler and transported under chain-of-custody procedure, to CF for analysis. The groundwater confirmation samples were analyzed for MBTEXN and TPH-GRO using U.S. EPA Method 8260D and TPH-DRO using U.S. EPA Method 8015D with SGT. 3.7 Monitoring Well Installation, Development, Surveying, and Sampling On October 4, 2024, after completion of the remedial activities, two properly constructed monitoring wells (MW-6 and MW-7) were installed at the Site. Monitoring well MW-6 was completed within the footprint, but on the hydraulically downgradient portion, of EXC-4, and monitoring well MW-7 was completed just north (hydraulically downgradient) of EXC-4. Both monitoring well locations are shown on Figures 2 and 3. Monitoring well construction logs are presented as Appendix H. Each well was completed as follows: • Well screen was placed from 5 to 15 feet bgs and consisted of 0.01-slot, schedule 40, 2-inch polyvinyl chloride (PVC) well screen material. • Placement of a flat bottom well foot at the bottom of the screen. Remedial Action Plan Implementation Report Former Sommers Auto Wrecking Wasatch Environmental, Inc. Page 10 • Well casing attached to the top of the screen and extending to approximately 0.5 feet bgs consisting of schedule 40, 2-inch PVC, well casing material. • A 10/20 filter pack sand material was placed in the annulus space from approximately 3 to 15 feet bgs. • A bentonite well seal was placed in the annulus space from approximately 1 to 3 feet bgs. • A surface completion consisting of a steel flush-mount well vault placed in concrete. Approximately 24 hours after the monitoring wells were installed, Wasatch developed each monitoring using over pumping techniques with a submersible pump. Well development was performed to reduce the turbidity of each well to provide low turbidity samples during the groundwater sampling activities. Wasatch considered well development to be completed once a minimum of five casing volumes of groundwater had been purged from the well or the well showed significant improvement in turbidity. The wells were allowed to equilibrate for at least 72 hours prior to the collection of groundwater samples. On October 7, 2024, Wasatch collected groundwater samples from and surveyed the top-of-casing (TOC) elevations of monitoring wells MW-6 and MW-7. The well TOCs were surveyed using LaserPlane surveying equipment to the nearest one-hundredth of a foot and were surveyed into the previously established arbitrary datum of 100.00 feet at the Site. Prior to groundwater sample collection, Wasatch collected depth-to-water measurements with an electronic interface water level probe from both monitoring wells. The interface probe was decontaminated between each well by washing with an Alconox® and distilled water solution, followed by a triple rinse of distilled water. A new disposable bailer was used to purge each monitoring well prior to sample collection. Both monitoring wells were sampled using standard purge sampling techniques and purged of at least three casing volumes of water. Groundwater samples were dispensed into appropriate laboratory-supplied sample containers, using gloved hands, placed in a cooler with ice, and transported under chain-of-custody protocol to CF for analysis. The groundwater samples were analyzed for TPH-GRO and MBTEXN using U.S. EPA Method 8260D and TPH-DRO using U.S. EPA Method 8015D with SGT. Additionally, groundwater sample MW-7 was also analyzed for TPH-GRO fractionation using U.S. EPA Method 8260D. Produced groundwater was thin spread on the ground surface near the wells they originated from. 3.8 Waste Characterization Sampling On June 17, 2024, Wasatch completed several test pits within the proposed excavation areas (EXC-1 through EXC-4) at the Site to complete waste characterization of the proposed soil waste. The soil samples collected from EXC-1, EXC-2, and EXC-3 were composited to represent a single sample (designated EXC-1-3 WCS) representing the metals-impacted soil waste. Additionally, the test pits completed within EXC-4 were composited to represent a single sample (designated Test Pit WCS) representing the petroleum-impacted soil waste. This was done to obtain approval to dispose of the waste at the Intermountain Regional Landfill (IRL). The RAP stated that soil waste would be disposed at the Salt Lake County Landfill (for metals impacted soil) and at ET Technologies Soil Regeneration Site (for petroleum hydrocarbon-impacted soil); however, the Volunteer elected to dispose of the soil waste at the IRL. Wasatch coordinated with the VCP on this change and obtained VCP concurrence that we could dispose of the soil waste at the IRL. Remedial Action Plan Implementation Report Former Sommers Auto Wrecking Wasatch Environmental, Inc. Page 11 Soil sample aliquots were collected from every foot of each test pit for the planned depths of the associated excavations and placed into a Ziploc® bag. Once all aliquots had been collected for each waste characterization sample, the aliquots were properly homogenized. The soil waste characterization samples were collected using gloved hands, placed in appropriate laboratory-supplied sample containers, and placed on ice. The soil waste characterization samples were delivered under chain-of-custody to CF for analysis. The EXC-1-3 WCS sample was analyzed for total and TCLP arsenic and lead by U.S. EPA Method 6010D. The Test Pit WCS sample was analyzed for pH using U.S. EPA Method 9045D, flash point using U.S. EPA Method 1010Mod, Resource Conservation and Recovery Act (RCRA) D and F-list toxicity characteristic leaching procedure (TCLP) and total VOCs using U.S. EPA Method 8260D, O&G using U.S. EPA Method 1664BMod, percent passing using U.S. EPA Method 1311, and RCRA D and F-list TCLP and total metals using U.S. EPA Methods 6010D/7471A. This sampling was conducted to facilitate the completion of the appropriate waste profiles to be approved by IRL. The Volunteer submitted the waste characterization data and completed waste profiles to the IRL for approval. IRL approved the waste for disposal prior to commencement of the excavation work. See Appendix I for waste approval and disposal documentation. 3.9 General Demolition and Construction Practices The following best management practices were employed during the implementation of the remedies: • The VCP was notified and provided with an opportunity to be present on-Site to observe the remedial activities. • No storm drains were located near any of the excavations or haul routes; therefore, no mitigation activities were required to prevent contaminants from entering the storm sewer system. • The soil excavation subcontractor was required to decontaminate their equipment prior to arrival at the Site, and prior to demobilization from the Site. • A track-out area was constructed by the excavation subcontractor and utilized for any heavy equipment leaving the Site to prevent tracking mud and/or contaminants onto public roadways. • Site access was limited by the existing fencing located at the Site. 4. REMEDIAL RESULTS 4.1 VCP-Requested Sampling Analyte concentrations in the composite surface soil samples were compared to the calculated SSCLs. The composite surface soil sample analytical data are summarized in Table 1. The laboratory analytical report for the soil samples is presented in Appendix J. No analytes were detected at concentrations exceeding the calculated SSCL risk thresholds in any of the samples. 4.2 Test Pit Sampling Analyte concentrations in the test pit soil samples were compared to the U.S. EPA RSLs for Residential and Industrial Soil, Utah ISLs, and the calculated SSCLs. The test pit soil sample analytical data are summarized in Table 1. The laboratory analytical report for the soil samples is presented in Appendix J. Remedial Action Plan Implementation Report Former Sommers Auto Wrecking Wasatch Environmental, Inc. Page 12 Soil sample TP-2 (5’-6’) exhibited a benzene concentration of 0.75 mg/kg which exceeds the Utah ISL for benzene of 0.2 mg/kg. However, this concentration was below U.S. EPA RSL for Residential Soil (1.2 mg/kg) and Industrial Soil (5.1 mg/kg). Additionally, this concentration is below the all compared calculated SSCLs. No other analytes were detected in any other sample at concentrations that exceed the applicable cleanup goals. 4.3 Impacted Soil Excavation and Off-Site Disposal Four excavations (EXC-1, EXC-2, EXC-3, and EXC-4) were completed at the Site that facilitated the removal and disposal of petroleum hydrocarbon and metal-impacted soil exceeding the applicable U.S. EPA RSLs for Industrial Soil and/or calculated SSCLs at the Site. See Figure 3 for the excavation locations and extents. A total of 4,065.81 tons of petroleum hydrocarbon and metal-impacted soil was excavated and disposed off-Site at IRL. The waste disposal documentation (including the waste profile, waste characterization laboratory report, and waste manifests) is presented in Appendix I. 4.3.1 EXC-1, EXC-2, and EXC-3 Excavations Excavation EXC-1 extended to a depth of approximately 0.5 feet bgs and measured approximately 80 feet east to west and 120 feet north to south with an approximate area of 9,600 square feet. Excavation EXC-2 extended to a depth of approximately 4 feet bgs and measured approximately 32 feet east to west and 31 feet north to south with an approximate area of 992 square feet. Excavation EXC-3 extended to a depth of approximately 5 feet bgs and measured approximately 25 feet east to west and 37 feet north to south with an approximate area of 925 square feet. 4.3.2 EXC-4 Excavation Excavation EXC-4 extended to a depth of approximately 9 feet bgs within the western portion of the excavation and 4 feet bgs within the eastern portion of the excavation, and measured approximately 120 feet east to west and 100 feet north to south with an approximate area of 12,000 square feet. 4.4 Extraction, Treatment, and Disposal of Petroleum-Impacted Groundwater Groundwater was encountered at approximately 6 to 7 feet bgs in the EXC-4 excavation. Free product was absorbed using absorbent pads, contained into a metal 55-gallon drum, and properly disposed of at the Clean Harbors Grassy Mountain Facility. The extracted groundwater was successfully aerated to remove VOCs and discharge through a bag filter and GAC vessel. Prior to discharging the treated groundwater, Wasatch collected a batch discharge sample just after the treatment train. Based on the analytical results of the discharge sample, all analyte concentration permit requirements were met and approximately 40,000 gallons of petroleum-impacted groundwater were treated and disposed of to the municipal the stormwater sewer. Upon completion of the batch discharge, Wasatch submitted a NOT form to the UDWQ to terminate the permit. UDWQ has since terminated this permit. 4.5 Soil Confirmation Sampling Analyte concentrations in the soil confirmation samples were compared to the U.S. EPA RSLs for Residential and Industrial Soil (for MBTEXN and metals), the Utah ISLs (for TPH-GRO, TPH-DRO, and O&G), and the calculated SSCLs (for TPH-GRO, TPH-DRO, and O&G). The soil confirmation sample Remedial Action Plan Implementation Report Former Sommers Auto Wrecking Wasatch Environmental, Inc. Page 13 analytical data are summarized in Table 1 and 3. The laboratory analytical reports for the soil confirmation samples are presented in Appendix J. A total of 19 soil confirmation samples (including two duplicate samples) were collected from excavation EXC-1. Soil confirmation samples collected from excavation EXC -1 exhibited the following: • Lead was detected in all twenty soil confirmations samples at concentrations ranging from 112 mg/kg to 629 mg/kg. Thirteen of the 19 soil confirmation samples collected from EXC-1 exhibited lead concentrations above the U.S. EPA RSL for Residential Soil; however, none of these concentrations exceeded the U.S. EPA RSL for Industrial Soil for lead. A total of seven soil confirmation samples (including one duplicate sample) were collected from excavation EXC-2. Soil confirmation samples collected from excavation EXC-2 exhibited the following: • Lead was detected in all seven soil confirmations samples at concentrations ranging from 165 mg/kg to 668 mg/kg. Six out of the seven soil confirmation samples collected from excavation EXC-2 exhibited lead concentrations above the U.S. EPA RSL for Residential Soil; however, none of these concentrations exceeded the U.S. EPA RSL for Industrial Soil for lead. • Arsenic was detected in all seven soil confirmations samples at concentrations ranging from 12.6 mg/kg to 24.4 mg/kg. All seven soil confirmation samples collected from EXC-2 exhibited arsenic concentrations exceeding both the U.S. EPA RSLs for Residential (0.68 mg/kg) and Industrial Soil (3 mg/kg); however, none of these concentrations exceed the VCP-approved arsenic cleanup goal for soil of 45 mg/kg. A total of six soil confirmation samples (including one duplicate sample) were collected from excavation EXC-3. Soil confirmation samples collected from excavation EXC -3 exhibited the following: • Lead was detected in all six soil confirmations samples at concentrations ranging from 47.5 mg/kg to 766 mg/kg. One out of six soil confirmation samples collected from excavation EXC-3 exhibited a lead concentration above the U.S. EPA RSL for Residential Soil; however, this concentration did not exceed the U.S. EPA RSL for Industrial Soil for lead. • Arsenic was detected in all six soil confirmations samples at concentrations ranging from 11.0 mg/kg to 21.4 mg/kg. All six soil confirmation samples collected from EXC-3 exhibited arsenic concentrations exceeding both the U.S. EPA RSLs for Residential and Industrial Soil; however, none of these concentrations exceed the VCP-approved arsenic in soil cleanup goal. A total of eighteen soil confirmation samples (including two duplicate samples) were collected from excavation EXC-4. Soil confirmation samples collected from excavation EXC-4 exhibited the following: • Soil confirmation sample EXC-4-NE exhibited a TPH-DRO concentration of 10,000 mg/kg, which exceeds the Utah ISL for TPH-DRO of 500 mg/kg. Following receipt of the analytical results, additional soil was excavated from the area where soil confirmation sample EXC-4-NE was collected and a second soil confirmation sample (designated EXC -4-NE2) was collected approximately 10 feet north of the previous sample. No analytes were detected in soil confirmation sample EXC-4-NE2 at concentrations exceeding their applicable Utah ISLs. • Soil confirmation sample EXC-4-West 3 exhibited TPH-GRO (1,500 mg/kg), ethylbenzene (164 mg/kg), and total xylenes (794 mg/kg) concentrations that exceeded their applicable Utah ISLs for TPH-GRO (150 mg/kg), ethylbenzene (5 mg/kg), and total xylenes (142 mg/kg). Naphthalene Remedial Action Plan Implementation Report Former Sommers Auto Wrecking Wasatch Environmental, Inc. Page 14 was detected at a concentration of 50.4 mg/kg. This concentration does not exceed the Utah ISL for naphthalene (51 mg/kg), but exceeds the U.S. EPA RSL for Residential (2 mg/kg) and Industrial Soil (8.6 mg/kg). The detected ethylbenzene concentration in EXC-4-West 3 also exceeded the U.S. EPA RSL for Industrial Soil of 25 mg/kg. Following receipt of the analytical results, additional soil was excavated from the area (the western EXC-4 sidewall) where soil confirmation sample EXC-4-West 3 was collected and a second soil confirmation sample (designated EXC-4-West 4) was collected as close to the west boundary of the Site as possible. Soil confirmation sample EXC-4-West 4 also exhibited TPH-GRO (3,150 mg/kg), ethylbenzene (103 mg/kg), and total xylenes (604 mg/kg) concentrations that were still above their respective Utah ISLs and/or U.S. EPA RSLs for Industrial Soil. Naphthalene was detected at a concentration of 28.1 mg/kg. This concentration does not exceed the Utah ISL for naphthalene, but exceeds the U.S. EPA RSL for Residential and Industrial Soil. Additionally, benzene (4.41 mg/kg) was detected in soil confirmation sample EXC-4-Floor 4 at a concentration that exceeded the Utah ISL of 0.2 mg/kg, but was below the U.S. EPA RSL for Industrial Soil of 5.1 mg/kg. Due to the presence of multiple underground utilities, additional excavation to the west was not possible. • Soil confirmation sample EXC-4-West 4 was also analyzed for TPH-GRO fractionation and TPH- DRO fractionation and exhibited the following concentrations: C5-C6 aliphatic hydrocarbons at 229 mg/kg, C7-C8 aliphatic hydrocarbons at 313 mg/kg, C9-C10 aliphatic hydrocarbons at 453 mg/kg, and C9-C10 alkyl benzenes at 1,420 mg/kg. These detections are below the calculated SSCLs for their applicable Outdoor Air Vapor Inhalation (OAVI) SSCLs and Ingestion of Soil SSCLs. See Table 1 for the calculated SSCLs. • No other soil confirmation samples collected from excavation EXC -4 exhibited analyte concentrations above their applicable Utah ISLs and/or U.S. EPA RSLs for Industrial Soil. 4.6 Groundwater Confirmation Sampling Analyte concentrations in the groundwater confirmation samples were compared to the Utah ISLs, the calculated SSCLs, and the U.S. EPA MCLs. The groundwater confirmation sample analytical data are summarized in Table 2. The laboratory analytical reports for the groundwater confirmation samples are presented in Appendix J. Benzene was detected in groundwater confirmation samples EXC -4-GW1 and EXC-4-GW2. Both groundwater confirmation samples exhibited a benzene concentration of 8 micrograms per liter (µg/L), which exceeds both the Utah ISL and the U.S. EPA MCL for benzene of 5 µg/L, but was well below the calculated OAVI SSCL of 283. No other analytes were detected in the groundwater confirmation samples at concentrations exceeding their applicable Utah ISLs, SSCLs, or U.S. EPA MCLs. 4.7 Monitoring Well Installation, Development, Surveying, and Sampling Monitoring wells MW-6 and MW-7 were successfully installed, developed, surveyed, and sampled. Each well was developed by purging approximately 20 to 25 gallons of water from the well, which reduced the groundwater turbidity observed in the purge water. Analyte concentrations in the groundwater samples were compared to the Utah ISLs, the calculated SSCLs, and the U.S. EPA MCLs. The groundwater sample analytical data are summarized in Table 2. The laboratory analytical reports for the groundwater samples are presented in Appendix J. No analytes were detected in the MW-6 groundwater sample. Remedial Action Plan Implementation Report Former Sommers Auto Wrecking Wasatch Environmental, Inc. Page 15 The MW-7 groundwater sample exhibited a TPH-GRO concentration of 1,780 µg/L and a TPH-DRO concentration of 1,400 µg/L. Both of these concentrations slightly exceed their Utah ISLs for TPH-GRO of 1,000 µg/L and TPH-DRO of 1,000 µg/L. Given these detections the TPH-GRO fractionation of this sample was completed. None of the TPH-GRO fractionation analytes exhibited concentrations that exceed the calculated OAVI SSCLs. No other analytes were detected at concentrations that exceed their applicable Utah ISLs or U.S. EPA MCLs in the MW-7 groundwater sample. 4.8 Waste Characterization Sampling The laboratory analytical results from the soil waste characterization samples indicated that the soil was, in Wasatch’s opinion, non-hazardous and suitable for disposal at a Subtitle D solid waste landfill. IRL approved the waste for disposal prior to the commencement of the excavation activities. See Appendix I for waste approval and disposal documentation. 5. QUALITY ASSURANCE/QUALITY CONTROL (QA/QC) QA/QC checks were performed for both field sampling and laboratory analysis of the environmental samples to allow for the evaluation of data quality, documentation of data quality, and to help identify irregularities in the field sampling or laboratory analyses that may require correction. 5.1 QA/QC Summary QA/QC samples were collected as specified in the approved QAPP. 5.1.1 Precision (Field and Laboratory Data Precision) As determined by the third-party data validator, the overall field/laboratory precision for this project is 93.6%, and no data was rejected; therefore, the precision is considered to be acceptable and under control. 5.1.2 Accuracy (Field and Laboratory Data Accuracy) As determined by the third-party data validator, the overall field/laboratory accuracy for this project is 92.7%, and no data was rejected; therefore, the accuracy is considered to be acceptable and under control. 5.1.3 Representativeness (Field and Laboratory Data Representativeness) Field: For this project, the environmental samples were collected from locations either reasonably believed to be, or established to be, representative to identify source areas, evaluate the nature of the release(s), and delineate the extent of contamination. Laboratory: For this project, method blanks were free of target analytes, sample holding times were not exceeded, all samples were properly preserved, receiving temperatures were not exceeded; therefore, representativeness for the project is considered acceptable an d under control. Overall, 99.6% of the representativeness-related parameters met the project requirements. 5.1.4 Completeness (Field and Laboratory Data Completeness) All samples (100%) collected were deemed valid based on an independent data validation. Completeness for the project is considered acceptable and under control. Remedial Action Plan Implementation Report Former Sommers Auto Wrecking Wasatch Environmental, Inc. Page 16 5.1.5 Comparability (Field and Laboratory Data Comparability) Comparability for the project is considered acceptable and under control. 5.1.6 Sensitivity (Field and Laboratory Data Sensitivity) Laboratory detection limits were less than the regulatory screening levels (except in limited instances where sample dilution was required); therefore, sensitivity for the project is considered acceptable and under control. The data validation reports completed by an independent third-party are presented as Appendix K for detailed review. No significant QA/QC, QAPP, SAP, or RAP deviations were discovered for this project. 6. CONCLUSIONS AND RECOMMENDATIONS It is Watch’s opinion that remedial actions completed at the Site have been successful at reducing contaminant impacts at the Site. None of the DU surface soil samples collected to further evaluate the petroleum hydrocarbon impacts exhibited petroleum hydrocarbon impacts that exceeded the applicable SSCLs. Therefore, remedial activities are not required for the areas sampled. None of the test pit soil samples exceeded their applicable U.S. EPA RSL for Industrial Soil and/or their applicable calculated SSCLs. Therefore, the originally anticipated EXC-4 extent was reduced in size accordingly. Based on the EXC-1, EXC-2, and EXC-3 soil confirmation data, metals impacts to soil at the Site have been remediated to concentrations below the VCP-approved cleanup goals. No EXC-4 soil confirmation samples exceeded their applicable calculated OAVI or Ingestion of Soil SSCLs. Although not considered a cleanup goal, Wasatch compared the test pit and soil confirmation samples to the calculated Indoor Air Vapor Inhalation (IAVI) SSCLs. Only one soil confirmation sample (EXC-4-West 4) exceeded the IAVI SSCL for benzene. Additionally, only one test pit sample (TP-2 (5’-6’) exceeded the IAVI SSCL for benzene. Given this, and to be conservative, Wasatch recommends that if future buildings are constructed in this area, a vapor mitigation system be installed to mitigate potential vapor intrusion risks in this area. Wasatch would include the details of potential vapor mitigation systems in an EC and SMP to be completed and submitted to the VCP for approval under a separate cover. Only one final soil confirmation sample (EXC-4-West 4), located along the northwestern sidewall of EXC- 4, exhibited an ethylbenzene and naphthalene concentration that exceeded their U.S. EPA RSL for Industrial Soil. The sidewall where EXC-4-West 4 was collected was extended to the west to the Site boundary and to where multiple underground utilities were encountered, thus prohibiting additional excavation of these impacts. However, the detected ethylbenzene and naphthalene concentrations were below the calculated Ingestion of Soil and OAVI SSCLs. Based on the EXC-4 soil confirmation data, petroleum-impacted soil located on-Site has been sufficiently remediated and now met the VCP-approved cleanup goals. Given the number of utilities present adjacent west of EXC-4 which are impeding further remediation or investigation, and that the petroleum impacts to soil adjacent west of EXC-4 are likely minor, it is Wasatch’s opinion that potential exposures to these potential residual petroleum impacts be mitigated through the use of a Blue Stakes of Utah Notice. This would notify future construction workers that may encounter these impacts, allowing them to take the appropriate precautions to work safely in that environment. The extraction, treatment, and disposal of petroleum-impacted groundwater originating from EXC-4 appear to have been effective. Benzene was the only analyte detected in the groundwater confirmation samples collected from EXC-4 at a concentration that slightly exceeded the Utah ISL. However, the Remedial Action Plan Implementation Report Former Sommers Auto Wrecking Wasatch Environmental, Inc. Page 17 detected benzene concentrations were well below the groundwater cleanup goal for the calculated OAVI SSCL. Given this and the EXC-4 soil confirmation data, it is Wasatch’s opinion that the petroleum hydrocarbon source area has been sufficiently remediated. MW-6 was installed on the downgradient portion of EXC-4 (within the former petroleum hydrocarbon source area), and MW-7 was installed hydraulically downgradient of EXC-4 to evaluate impacts migrating to the boundary of the Site. No analytes were detected in the MW-6 groundwater sample, and only low concentrations of TPH-GRO and TPH-DRO were detected in the MW-7 groundwater sample at a concentration just above the applicable Utah ISLs. Based on the MW-7 fractionation data, none of the SSCLs were exceeded by these reported concentrations. Benzene was not detected in either of the MW- 6 and MW-7 groundwater samples. Therefore, it is Wasatch’s opinion that petroleum hydrocarbon groundwater impacts reaching the Site boundary are likely not of concern and do not require active remediation. None of the groundwater confirmation or the MW-6 and MW-7 groundwater samples exhibited analyte concentrations that exceeded any of the calculated SSCLs. Previous groundwater samples (GP -19, GP- 20, and GP-21) collected hydraulically downgradient (and across 700 West) of the Site and EXC-4, did not detect any petroleum hydrocarbons at concentrations that exceed the Utah ISLs or U.S. EPA MCLs. Given that benzene in groundwater is not reaching the Site boundary (based on the sampled locations) and that no petroleum hydrocarbons were detected hydraulically downgradient of the Site even prior to remedial actions, it is Wasatch’s opinion that any petroleum-impacted groundwater leaving the Site is likely minor and considered to be a de minimis condition. Wasatch recommends that an EC and SMP be completed for the Site, and that upon completion of those documents that the release be granted regulatory closure by the DERR. Wasatch anticipates the EC and SMP may include, but is not limited to, the following restrictions: restrict the use of groundwater at the Site, no ground floor residential structures, properly impacted media handling instructions for construction workers at the Site, and if impacted soil is required to be removed from the Site coordination with the VCP may be required.

California Ave.Salt Lake City DESCRIPTION OF WORK Wasatch plans to complete 4 shallow soil excavations to remove metals and petroleum impacted soil and dispose of the soil off-site. The soil will be direct loaded into dump trucks and transported off-site for disposal (see the attached map for excavation locations and areas). Wasatch obtained (see attachment) a Treated Groundwater Discharge permit from the Utah DWQ, as we will be extracting groundwater from EXC-4 to facilitate the soil excavation activities. The groundwater will be pumped into a 21,000-gallon frack tank and discharged as a batch discharge. The the treated water will be run through a bag filter to remove sediments and then through a granular activated carbon vessel to remove any contaminants from the discharge. Per the DWQ permit, prior to discharge, the water will be sampled to verify we meet the permit discharge requirements. Wasatch plans to discharge the treated groundwater to the storm water drain depicted on the attached map. See the attached BMPs and fugitive dust plan for the excavation activities. All excavations will be backfilled and compacted upon completion of the remediation activities. We will add inlet protections (straw waddles or filter pads) to the storm water drains located on-site and just south-west of the project.

INTRODUCTION This Fugitive Emissions Monitoring Plan (Plan) has been prepared for soil remediation activities at the former Sommers Auto Wrecking property, an industrial property, consisting of 5.15 acres, located at 647 West 3300 South in South Salt Lake, Utah (Site). Heavy metal and petroleum hydrocarbon impacted soil is located at the Site. These impacted soil will be excavated and disposed off-Site. This Plan will be followed by the general contractor and all subcontractors during excavation, stockpiling, on-Site relocation, and backfilling activities on the Site. 2. OBJECTIVES The purpose of this Plan is to describe the fugitive dust control measures and Best Management Practices (BMPs) that will be followed during soil excavation and backfilling activities to minimize the generation of fugitive dust. Also described is the monitoring approach to evaluate effectiveness of the dust control BMPs and to document those adjoining residents and workers involved with on-Site activities are not exposed to fugitive dust, and that the State of Utah opacity limits are met. Potential exposures to fugitive dust emissions by commercial/industrial properties in areas adjacent to the Site and workers involved with impacted soil removal activities will be assessed using U.S. EPA Method 9 (Visual Determination of Opacity of Emissions from Stationary Sources) at the Site. The equipment expected to be used during on-Site activities with the potential to generate fugitive dust includes haul trucks, skidsters, front end loaders, water trucks, and excavators. A majority of this equipment is not used on public roads so track-out is not expected to be an issue although it will be monitored and prevented to the extent feasible. A temporary, stabilized gravel track-out pad will be in place and steps will be taken to minimize track-out from equipment onto public roads. By complying with the State of Utah Opacity limits, the National Ambient Air Quality Standards for particulate matter, both particle sizes below 10 microns in diameter (PM10) and 2.5 microns in diameter (PM2.5) will also be met. The daily limit for PM10 is 150 micrograms per cubic meter (ug/m3) and the daily limit for PM2.5 is 35 ug/m3. 3. DUST CONTROL MEASURES/BEST MANAGEMENT PRACTICE Attached to this Plan (as Appendix 1) is the Utah Division of Air Quality (DAQ) approved Fugitive Dust Control Plan for the former Sommers Auto Wrecking project, which describes the construction BMPs to minimize the generation of fugitive dust. These practices include the use of water to wet soils and haul roads, and to form a crust on open soils. The Plan also discusses wetting stockpiles, maintaining low drop heights when loading material, using gravel in lay-down areas, limiting vehicle speeds, and the proper application of track-out controls. This Plan will be presented to the contractor and any subcontractors during initial Site training activities. The Plan requires that all construction activities meet opacity requirements in R307-309-5. It is Wasatch’s experience that wetting of soil greatly decreases any dust generation. FUGITIVE DUST CONTROL PLAN Former Sommers Auto Wrecking Wasatch Environmental, Inc. 2 Also attached to this Plan (as Appendix 2) is a wind rose diagram of frequency of wind direction and speed during November 2022. The diagram shows that the prevailing winds are generally expected to be out of the south to southeast, or from the northwest. The month of November is representative of the winds from late summer through the late fall. It is Wasatch’s experience that heavy watering of stockpiles (if used) and exposed soil prior to ending work before the weekend is effective in forming a “crust” on the soil which should reduce fugitive dust generation. However, if strong winds are predicted during overnight hours or weekends, arrangement will be made to provide additional watering. 4. DAILY MONITORING Wasatch personnel will be on-Site during all soil removal and backfilling activities to screen soils using a hand-held photoionization detector, collect confirmation soil samples for laboratory analysis, direct Health and Safety meetings and training, and implement the fugitive dust control and monitoring procedures described in this Plan. Compliance with the Utah opacity limits (20% opacity at the generation source and 10% opacity at the perimeter) will be assessed using U.S. EPA Method 9, modified to account for non-stationary sources. For non-stationary sources, which would apply to vehicles on-Site, opacity readings are directed to a point not less than one-half the vehicle length behind the vehicle and not less than one half the vehicle height. During soil remediation activities, Wasatch personnel trained as Visible Emission Observers will make opacity observations at the point of generation and the down-wind property line, as well as at non- stationary sources such as moving vehicles and/or equipment. These readings will be recorded on a Visible Emissions Observation Form (Appendix 2), which includes weather conditions, wind speed and direction, type of activity occurring on-Site, and position of observer relative to dust source. Opacity readings will be made at least once daily, or as needed during peak work activities, or as weather conditions require. 5. ACTION LIMITS Utah opacity action limits will be used as action limits (20% opacity at the generation source and 10% opacity at the perimeter) for this project. Any concerns or indications that opacity action limits are being approached or exceeded will be immediately addressed by aggressively applying additional BMPs, including, as warranted; pre-watering, shifting the work area, curtailing certain types of work, or shutting down work activities. When the wind speeds exceed 25 miles per hour, Rule 307-309-5 (3) exempts the opacity limits as long as the operator continues to implement the approved fugitive dust control plan and administers at least one of the following control methods: pre-event watering, hourly watering, shifting work areas, or ceases or reduces dust producing operations. 6. REPORTING Wasatch will consult frequently (at least weekly) with Utah VCP to discuss, address, and work to remedy any fugitive dust control issues, including responding to resident complaints, re-evaluating, and modifying dust control procedures, and other related problems that may arise.

Is th is project a temporary relocation project?: Yes No N on-A ttainment Dust Tutorial W hat is Fugitive D ust? Fugitive dust is dust that is stirr ed up, creating an air quality pro blem. It is made up of ne particles called particulate matter. It is a health concern because it ir r itates eyes and nas al tissue and seriously impacts the r espir ator y system. x Fugitive dust may come from gravel o per ations, construction or demolition activities, land clear ing and exposed sur faces, r oadways, and mining activities. Tracko ut fr om muddy work areas also create fugitive dust when the mud dries. How We Measu re Compliance-Opac ity Opacity is the amount of light that is blo cked by something else such as smoke or a tinted window. The percentage of opacity can pro vide a measur e of the par ticulate matter in the air . Opacity is meas ur ed as a percentage - 0% means that all light passes thr ough; 100% means that no light can pass through. The more particles pr esent, the higher the opacity percentage.

Coverage under the Treated Groundwater and Surface Water General Permit for this facility is referred to as UPDES permit number UTG790107. The conditions and requirements of the permit will be effective for one year beginning July 16, 2024. For reference, a copy of the general permit is available at: https://deq.utah.gov/water-quality/current-permits-and-forms-updes- permitting-program#general-treated-gw. After reviewing your NOI and associated information, it was determined that effluent monitoring and limits will be required as described in section I.E of the Treated Groundwater and Surface Water General Permit. Effluent monitoring will also be required for Arsenic, Barium, Copper, and Zinc. The Division of Water Quality (DWQ) approves the request to monitor for TPH-GRO and TPH- DRO in lieu of the Total Toxic Organics (TTO) monitoring requirement. Prior to the first discharge event, the facility must submit the required sampling analysis in section I.E., and the additional required metals from a representative sample of treated effluent water. The initial monitoring shall be sent via email to lrshafer@utah.gov. After the facility has provided the initial monitoring results and has received the DWQ approval, the facility is authorized to discharge. Page 2 UTG790107 Former Sommers Auto Monitoring and Limit requirements for Permit No. UTG790107 are as follows: The permit requires that monitoring results be summarized and reported on a Discharge Monitoring Report (DMR). The DMR shall be submitted electronically monthly the Environmental Protection Agency’s (EPA) electronic reporting system: NetDMR https://npdes-ereporting.epa.gov/net- netdmr. The DMR is due by the 28th day of each month for the previous month’s discharge activity. When discharging activities cease, please notify the Division by submitting a Notice of Termination form, which can also be obtained at: https://deq.utah.gov/water-quality/current- permits-and-forms-updes-permitting-program#general UPDES General Permit Coverage for the Discharge of Treated Groundwater is for 12 months or less. Within 6 months of permit issuance, please evaluate your discharge timeline. If dewatering discharges are expected to extend greater than 12 months from the issuance date, an individual permit will need to be obtained. Individual permits require 6 months for issuance. Please keep DWQ informed of your project status. A fee schedule was included in the Utah Department of Environmental Quality Budget appropriation request at the direction of the Legislature and in accordance with Utah Code annotated 19-1-201. The fee schedule, as approved by the legislature, includes a fee for the General Permit for Treated Groundwater and Surface Water of $ 601.00 per year (see attached invoice).

Coverage under the Treated Groundwater and Surface Water General Permit for this facility is referred to as UPDES permit number UTG790107. The conditions and requirements of the permit will be effective for one year beginning July 16, 2024. For reference, a copy of the general permit is available at: https://deq.utah.gov/water-quality/current-permits-and-forms-updes- permitting-program#general-treated-gw. After reviewing your NOI and associated information, it was determined that effluent monitoring and limits will be required as described in section I.E of the Treated Groundwater and Surface Water General Permit. Effluent monitoring will also be required for Arsenic, Barium, Copper, and Zinc. The Division of Water Quality (DWQ) approves the request to monitor for TPH-GRO and TPH- DRO in lieu of the Total Toxic Organics (TTO) monitoring requirement. Prior to the first discharge event, the facility must submit the required sampling analysis in section I.E., and the additional required metals from a representative sample of treated effluent water. The initial monitoring shall be sent via email to lrshafer@utah.gov. After the facility has provided the initial monitoring results and has received the DWQ approval, the facility is authorized to discharge. Page 2 UTG790107 Former Sommers Auto Monitoring and Limit requirements for Permit No. UTG790107 are as follows: The permit requires that monitoring results be summarized and reported on a Discharge Monitoring Report (DMR). The DMR shall be submitted electronically monthly the Environmental Protection Agency’s (EPA) electronic reporting system: NetDMR https://npdes-ereporting.epa.gov/net- netdmr. The DMR is due by the 28th day of each month for the previous month’s discharge activity. When discharging activities cease, please notify the Division by submitting a Notice of Termination form, which can also be obtained at: https://deq.utah.gov/water-quality/current- permits-and-forms-updes-permitting-program#general UPDES General Permit Coverage for the Discharge of Treated Groundwater is for 12 months or less. Within 6 months of permit issuance, please evaluate your discharge timeline. If dewatering discharges are expected to extend greater than 12 months from the issuance date, an individual permit will need to be obtained. Individual permits require 6 months for issuance. Please keep DWQ informed of your project status. A fee schedule was included in the Utah Department of Environmental Quality Budget appropriation request at the direction of the Legislature and in accordance with Utah Code annotated 19-1-201.

Coverage under the Treated Groundwater and Surface Water General Permit for this facility is referred to as UPDES permit number UTG790107. The conditions and requirements of the permit will be effective for one year beginning July 16, 2024. For reference, a copy of the general permit is available at: https://deq.utah.gov/water-quality/current-permits-and-forms-updes- permitting-program#general-treated-gw. After reviewing your NOI and associated information, it was determined that effluent monitoring and limits will be required as described in section I.E of the Treated Groundwater and Surface Water General Permit. Effluent monitoring will also be required for Arsenic, Barium, Copper, and Zinc. The Division of Water Quality (DWQ) approves the request to monitor for TPH-GRO and TPH- DRO in lieu of the Total Toxic Organics (TTO) monitoring requirement. Prior to the first discharge event, the facility must submit the required sampling analysis in section I.E., and the additional required metals from a representative sample of treated effluent water. The initial monitoring shall be sent via email to lrshafer@utah.gov. After the facility has provided the initial monitoring results and has received the DWQ approval, the facility is authorized to discharge. Page 2 UTG790107 Former Sommers Auto Monitoring and Limit requirements for Permit No. UTG790107 are as follows: The permit requires that monitoring results be summarized and reported on a Discharge Monitoring Report (DMR). The DMR shall be submitted electronically monthly the Environmental Protection Agency’s (EPA) electronic reporting system: NetDMR https://npdes-ereporting.epa.gov/net- netdmr. The DMR is due by the 28th day of each month for the previous month’s discharge activity. When discharging activities cease, please notify the Division by submitting a Notice of Termination form, which can also be obtained at: https://deq.utah.gov/water-quality/current- permits-and-forms-updes-permitting-program#general UPDES General Permit Coverage for the Discharge of Treated Groundwater is for 12 months or less. Within 6 months of permit issuance, please evaluate your discharge timeline. If dewatering discharges are expected to extend greater than 12 months from the issuance date, an individual permit will need to be obtained. Individual permits require 6 months for issuance. Please keep DWQ informed of your project status. A fee schedule was included in the Utah Department of Environmental Quality Budget appropriation request at the direction of the Legislature and in accordance with Utah Code annotated 19-1-201. The fee schedule, as approved by the legislature, includes a fee for the General Permit for Treated Groundwater and Surface Water of $ 601.00 per year (see attached invoice).

No preparation issues were noted. Method Blanks All blank values were within method acceptance criteria. No blank values exceeded the minimum reporting limit for any analysis in this work order, with the following exceptions: Arsenic and Lead were observed above the MRL in BYH1068-BLK1. The concentration in the method blank is less than 10% of the sample result, which is negligible according to method criteria. Laboratory Control Samples All laboratory control samples were within method acceptance criteria. Batch BYH1050 had low LCS recoveries for MTBE. It is important to note that certain flags on an individual analyte do not constitute failure of the method as a whole. EPA methodologies recognize that it may not be possible for every compound to meet all recovery or percent difference criteria . The batch passed required method criteria for these analytes. Method Spikes All method spike recoveries were within method acceptance criteria, except as noted by qualifying flags. Method Spike Duplicates All method spike duplicates were within method acceptance criteria, except as noted by qualifying flags.

No preparation issues were noted. Method Blanks All blank values were within method acceptance criteria. No blank values exceeded the minimum reporting limit for any analysis in this work order, with the following exceptions: Arsenic and Lead were observed above the MRL in BYH1068-BLK1. The concentration in the method blank is less than 10% of the sample result, which is negligible according to method criteria. Laboratory Control Samples All laboratory control samples were within method acceptance criteria. Batch BYH1050 had low LCS recoveries for MTBE. It is important to note that certain flags on an individual analyte do not constitute failure of the method as a whole. EPA methodologies recognize that it may not be possible for every compound to meet all recovery or percent difference criteria . The batch passed required method criteria for these analytes. Method Spikes All method spike recoveries were within method acceptance criteria, except as noted by qualifying flags. Method Spike Duplicates All method spike duplicates were within method acceptance criteria, except as noted by qualifying flags. Corrective Actions There are no corrective actions associated with this work order. www.ChemtechFord.com Project Name: Former Sommers Auto Wrecking CtF WO#: 24H1959 Page 2 of 22 xx Chemtech-Ford

microgram per liter or 1 ug/kg = one microgram per kilogram = 1 part per billion. 1 ng/L = one nanogram per liter or 1 ng/kg = one nanogram per kilogram = 1 part per trillion. On calculated parameters, there may be a slight difference between summing the rounded values shown on the report vs the unrounded values used in the calculation. Flag Descriptions B = Analyte is found in the associated blank as well as in the sample (CLP B-flag). J-LOW-L = Estimated low due to low recovery of LCS SPH = Sample submitted past method specified holding time.

GLOSSARY OF TERMS Guide to Reading and Understanding Your Laboratory Report The information below is designed to better explain the various terms used in your report of analytical results from the Laboratory. 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 COD Coefficient of Determination. (dry)Results are reported based on the dry weight of the sample. [this will only be present on a dry report basis for soils]. Mass Mass of parameter. MDL Method Detection Limit. MDL (dry)Method Detection Limit. RDL Reported Detection Limit. RDL (dry)Reported Detection Limit. Rec.Recovery. RPD Relative Percent Difference. RRF Relative Response Factor. RT Retention Time. SDG Sample Delivery Group. 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. 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. Wavelength Wavelength of parameter. 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 J1 Surrogate recovery limits have been exceeded; values are outside upper control limits. J4 The associated batch QC was outside the established quality control range for accuracy. 1 Cp 2 Tc 3 Ss 4 Cn 5 Su 6 Gl 7 Al 8 Sc ACCOUNT:PROJECT:SDG:DATE/TIME:PAGE: Wasatch Environmental SOMMERS AUTO L1766673 10/28/24 13:00 65 of 67 ACCOUNT:PROJECT:SDG:DATE/TIME:PAGE: Wasatch Environmental SOMMERS AUTO L1766673 10/28/24 14:36 65 of 67 Pace Analytical National 12065 Lebanon Rd Mount Juliet, TN 37122 Alabama 40660 Nebraska NE-OS-15-05 Alaska 17-026 Nevada TN000032021-1 Arizona AZ0612 New Hampshire 2975 Arkansas 88-0469 New Jersey–NELAP TN002 California 2932 New Mexico ¹TN00003 Colorado TN00003 New York 11742 Connecticut PH-0197 North Carolina Env375 Florida E87487 North Carolina ¹DW21704 Georgia NELAP North Carolina ³41 Georgia ¹923 North Dakota R-140 Idaho TN00003 Ohio–VAP CL0069 Illinois 200008 Oklahoma 9915 Indiana C-TN-01 Oregon TN200002 Iowa 364 Pennsylvania 68-02979 Kansas E-10277 Rhode Island LAO00356 Kentucky ¹ ⁶KY90010 South Carolina 84004002 Kentucky ²16 South Dakota n/a Louisiana AI30792 Tennessee ¹ ⁴2006 Louisiana LA018 Texas T104704245-20-18 Maine TN00003 Texas ⁵LAB0152 Maryland 324 Utah TN000032021-11 Massachusetts M-TN003 Vermont VT2006 Michigan 9958 Virginia 110033 Minnesota 047-999-395 Washington C847 Mississippi TN00003 West Virginia 233 Missouri 340 Wisconsin 998093910 Montana CERT0086 Wyoming A2LA A2LA – ISO 17025 1461.01 AIHA-LAP,LLC EMLAP 100789 A2LA – ISO 17025 ⁵1461.02 DOD 1461.01 Canada 1461.01 USDA P330-15-00234 EPA–Crypto TN00003 ACCREDITATIONS & LOCATIONS ¹ Drinking Water ² Underground Storage Tanks ³ Aquatic Toxicity ⁴ Chemical/Microbiological ⁵ Mold ⁶ Wastewater n/a Accreditation not applicable * Not all certifications held by the laboratory are applicable to the results reported in the attached report. * Accreditation is only applicable to the test methods specified on each scope of accreditation held by Pace Analytical. 1 Cp 2 Tc 3 Ss 4 Cn 5 Su 6 Gl 7 Al 8 Sc ACCOUNT:PROJECT:SDG:DATE/TIME:PAGE: Wasatch Environmental SOMMERS AUTO L1766673 10/28/24 13:00 66 of 67 ACCOUNT:PROJECT:SDG:DATE/TIME:PAGE: Wasatch Environmental SOMMERS AUTO L1766673 10/28/24 14:36 66 of 67 ANALYTICAL REPORT October 28, 2024 Wasatch Environmental Sample Delivery Group:L1770255 Samples Received:08/22/2024 Project Number: Description:Emergency Response and Remediation Split Samples Report To:Blake Downey 2410 West California Avenue Salt Lake City, UT 84104 Entire Report Reviewed By: October 28, 2024 [Preliminary Report] John Hawkins Project Manager Results relate only to the items tested or calibrated and are reported as rounded values.

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 Corr.Correlation Coefficient. (dry)Results are reported based on the dry weight of the sample. [this will only be present on a dry report basis for soils]. Incpt Intercept. Mass Mass of parameter. MDL Method Detection Limit. MDL (dry)Method Detection Limit. RDL Reported Detection Limit. RDL (dry)Reported Detection Limit. Rec.Recovery. RPD Relative Percent Difference. RSD Relative Standard Deviation. SDG Sample Delivery Group. 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. 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. Slope Slope of calibration curve. Uncertainty (Radiochemistry)Confidence level of 2 sigma. Wavelength Wavelength of parameter. 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 The remainder of this page intentionally left blank, there are no qualifiers applied to this SDG. 1 Cp 2 Tc 3 Ss 4 Cn 5 Su 6 Gl 7 Al 8 Sc ACCOUNT:PROJECT:SDG:DATE/TIME:PAGE: Wasatch Environmental L1770255 10/28/24 13:09 51 of 53 ACCOUNT:PROJECT:SDG:DATE/TIME:PAGE: Wasatch Environmental L1770255 10/28/24 14:36 51 of 53 Pace Analytical National 12065 Lebanon Rd Mount Juliet, TN 37122 Alabama 40660 Nebraska NE-OS-15-05 Alaska 17-026 Nevada TN000032021-1 Arizona AZ0612 New Hampshire 2975 Arkansas 88-0469 New Jersey–NELAP TN002 California 2932 New Mexico ¹TN00003 Colorado TN00003 New York 11742 Connecticut PH-0197 North Carolina Env375 Florida E87487 North Carolina ¹DW21704 Georgia NELAP North Carolina ³41 Georgia ¹923 North Dakota R-140 Idaho TN00003 Ohio–VAP CL0069 Illinois 200008 Oklahoma 9915 Indiana C-TN-01 Oregon TN200002 Iowa 364 Pennsylvania 68-02979 Kansas E-10277 Rhode Island LAO00356 Kentucky ¹ ⁶KY90010 South Carolina 84004002 Kentucky ²16 South Dakota n/a Louisiana AI30792 Tennessee ¹ ⁴2006 Louisiana LA018 Texas T104704245-20-18 Maine TN00003 Texas ⁵LAB0152 Maryland 324 Utah TN000032021-11 Massachusetts M-TN003 Vermont VT2006 Michigan 9958 Virginia 110033 Minnesota 047-999-395 Washington C847 Mississippi TN00003 West Virginia 233 Missouri 340 Wisconsin 998093910 Montana CERT0086 Wyoming A2LA A2LA – ISO 17025 1461.01 AIHA-LAP,LLC EMLAP 100789 A2LA – ISO 17025 ⁵1461.02 DOD 1461.01 Canada 1461.01 USDA P330-15-00234 EPA–Crypto TN00003 ACCREDITATIONS & LOCATIONS ¹ Drinking Water ² Underground Storage Tanks ³ Aquatic Toxicity ⁴ Chemical/Microbiological ⁵ Mold ⁶ Wastewater n/a Accreditation not applicable * Not all certifications held by the laboratory are applicable to the results reported in the attached report. * Accreditation is only applicable to the test methods specified on each scope of accreditation held by Pace Analytical. 1 Cp 2 Tc 3 Ss 4 Cn 5 Su 6 Gl 7 Al 8 Sc ACCOUNT:PROJECT:SDG:DATE/TIME:PAGE: Wasatch Environmental L1770255 10/28/24 13:09 52 of 53 ACCOUNT:PROJECT:SDG:DATE/TIME:PAGE: Wasatch Environmental L1770255 10/28/24 14:36 52 of 53 ANALYTICAL REPORT September 04, 2024 Wasatch Environmental Sample Delivery Group:L1771052 Samples Received:08/23/2024 Project Number: Description:Sommers Emergency Response Split Site:SOMMERS AUTO Report To:Blake Downey, P.G. 2410 West California Avenue Salt Lake City, UT 84104 Entire Report Reviewed By: September 04, 2024 [Preliminary Report] John Hawkins Project Manager Results relate only to the items tested or calibrated and are reported as rounded values.

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 Corr.Correlation Coefficient. (dry)Results are reported based on the dry weight of the sample. [this will only be present on a dry report basis for soils]. Incpt Intercept. Mass Mass of parameter. MDL Method Detection Limit. MDL (dry)Method Detection Limit. RDL Reported Detection Limit. RDL (dry)Reported Detection Limit. Rec.Recovery. RPD Relative Percent Difference. RSD Relative Standard Deviation. SDG Sample Delivery Group. 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. 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. Slope Slope of calibration curve. Uncertainty (Radiochemistry)Confidence level of 2 sigma. Wavelength Wavelength of parameter. 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. J3 The associated batch QC was outside the established quality control range for precision.

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 Corr.Correlation Coefficient. (dry)Results are reported based on the dry weight of the sample. [this will only be present on a dry report basis for soils]. Incpt Intercept. Mass Mass of parameter. MDL Method Detection Limit. MDL (dry)Method Detection Limit. RDL Reported Detection Limit. RDL (dry)Reported Detection Limit. Rec.Recovery. RPD Relative Percent Difference. SDG Sample Delivery Group. 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. 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. Slope Slope of calibration curve. Uncertainty (Radiochemistry)Confidence level of 2 sigma. Wavelength Wavelength of parameter. 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.

No preparation issues were noted. Method Blanks All blank values were within method acceptance criteria. No blank values exceeded the minimum reporting limit for any analysis in this work order, with the following exceptions: Arsenic and Lead were observed above the MRL in BYH1068-BLK1. The concentration in the method blank is less than 10% of the sample result, which is negligible according to method criteria. Laboratory Control Samples All laboratory control samples were within method acceptance criteria. Batch BYH1050 had low LCS recoveries for MTBE. It is important to note that certain flags on an individual analyte do not constitute failure of the method as a whole. EPA methodologies recognize that it may not be possible for every compound to meet all recovery or percent difference criteria . The batch passed required method criteria for these analytes. Method Spikes All method spike recoveries were within method acceptance criteria, except as noted by qualifying flags. Method Spike Duplicates All method spike duplicates were within method acceptance criteria, except as noted by qualifying flags.

Where specific guidance is not available, the data has been evaluated in a conservative manner consistent with industry standards using professional experience. This review was based exclusively on data reports, Quality Control (QC) summaries and raw data provided by the laboratory. The following are definitions of the data qualifiers, in addition to the laboratory qualifiers, that may be used in this report. J+ Data are qualified as estimated, with a high bias likely to occur. False positives or false negatives are unlikely to have been reported. J- Data are qualified as estimated, with a low bias likely to occur. False positives or false negatives are unlikely to have been reported. J Data are qualified as estimated; it is not possible to assess the direction of the potential bias. False positives or false negatives are unlikely to have been reported. R Data are qualified as rejected. There is a significant potential for the reporting of false negatives or false positives. UJ Indicates the compound or analyte was analyzed for but not detected. The sample detection limit is an estimated value. B The compound or analyte was found in an associated blank as well as in the sample. None Indicates the data was not significantly impacted by the finding, therefore qualification was not AQS, Inc. Data Validation Report Page 5 required. 2.0 Data Review 2.1 Sample Receipt Copies of the chain-of-custody (COC) forms were included in the laboratory data package. COCs were reviewed for accuracy, completeness, and evidence of correct sample preservation. No sample receipt problems were noted. 2.2 Holding Times All samples were analyzed within required holding times. 2.3 Reporting Levels The data user should ensure that all reporting levels meet project requirements. All samples were run undiluted, at normal laboratory reporting levels, with the following exceptions: Sample(s) Analyte(s) Notes Qualifiers Test Pit WCS Selenium, Total These analytes were reported as non-detect but were run diluted – elevating the detection limit. The data user should ensure that detection limits for non-detect results meet project requirements. None required TP - 3 ( 2'-3') TP - 4 ( 2'-3') DU-1 DU-2 DU-10 8270 TPH Fractionation (several ND analytes run at 20x dilution) These analytes were reported as non-detect but were run diluted – elevating the detection limit. The data user should ensure that detection limits for non-detect results meet project requirements. None required 24H1461 EXC-4-West2 EXC-4-West3 8270 TPH Fractionation (several ND analytes run at 10x dilution) These analytes were reported as non-detect but were run diluted – elevating the detection limit. The data user should ensure that None required AQS, Inc.

The purpose of implementing these procedures is to assess the data obtained with respect to the data quality parameters of precision, representativeness, accuracy, completeness, and comparability for both the laboratory analytical program and field sample collection activities. The primary goal of the program is to ensure that the data generated are representative of environmental conditions at the Site. To achieve this goal, a combination of quantitative procedures and qualitative evaluations will be used to assess the data quality. Precision Precision is a measure of mutual agreement among individual measurements of the same property, usually under prescribed similar conditions, and typically expressed in terms of the standard deviation or relative percent difference (RPD). Field Data Precision Field precision is assessed through the collection and analysis of field duplicates and comparing the analytical results of the field duplicates to the analytical results of the environmental samples. For groundwater field duplicates, a calculated RPD of 20% is deemed acceptable. For soil and indoor air duplicates, a calculated RPD of 50% is deemed acceptable.

Laboratory Data Precision Laboratory precision will be assessed through the calculation of RPD and/or relative standard deviations (RSD) for duplicate samples. Analytical precision will be measured by comparing analytical results for matrix spike (MS) and matrix spike duplicate (MSD) samples and internal laboratory samples that may be analyzed according to analytical method or laboratory standard operating procedure requirements. Acceptance criteria for analytical precision will be based on established laboratory quality control limits for individual analytes. Applicable control limits are based on statistically valid historical data compiled by the laboratory which meet or exceed precision requirements specified by the analytical method. Standard operating procedures are on file with the selected project laboratory. For laboratory duplicates, the RPDs within established laboratory control limits for each analyte are acceptable.

Data Quality Summary AQS, Inc. 7 Precision Assessment Overall, 93.6% of the field and laboratory duplicates met project requirements. Precision for the project is considered acceptable and under control. Accuracy Accuracy is the degree of agreement of a measurement with an accepted reference or true value. The accuracy of the analytical data is assessed by examining possible sources of error that may bias the analytical results. Field Data Accuracy Sources of the errors in the field can occur during sampling (i.e., cross contamination from sampling equipment, etc.), field handling, and transportation. Accuracy in the field will be assessed by documenting adherence to standard operating procedures for sample collection, preservation, and handling, and through preparation and analysis of trip blanks and equipment blanks. It is presumed that field operating procedures were followed. Sample receiving documentation indicates that proper sample collection, preservation and handling procedures were followed.

Data Quality Summary AQS, Inc. 8 Laboratory Data Accuracy Sources of errors in the laboratory can occur during sample preparation and analysis, duplicate and control sample preparation, and due to instrument and quantification errors. Laboratory accuracy is assessed through the analysis of standard reference materials (SRMs) in laboratory control samples, MSs, MSDs, and surrogate compounds and the determination of their recoveries in terms of percentage. Control limits are established by the laboratory for each analyte based on statistically valid historical recovery results, which meet or exceed the requirements specified by the analytical method. In addition, the project laboratory will analyze method blanks to determine the potential for contamination introduced at any stage of sample preparation or analysis. Laboratory control limits and frequency for spike recovery and method blank analysis are specified in standard operating procedures for each analytical method, which are on file with the selected project laboratory. Spike recoveries from laboratory control samples (LCSs) and MS/MSDs that are within established laboratory control limits for each analyte are considered acceptable.

Accuracy Assessment Overall, 92.7% of the accuracy-related parameters met project requirements. Accuracy for the project is considered acceptable and under control. Representativeness Representativeness is a qualitative parameter that expresses the degree to which sample data accurately and precisely represent a characteristic of a population, parameter variations at a sampling point, or an environmental condition. As such, representativeness requires the selection of appropriate analytical methods, sampling protocols, and sampling locations such that results are representative of the media being sampled and conditions being measured. Field Data Representativeness Representativeness is dependent upon the proper design of the sampling program and will be satisfied by ensuring that project requirements are followed. For this project, it is presumed that environmental samples are collected from locations either reasonably believed to be, or established to be, representative to identify source areas, evaluate the nature of the release(s), and delineate the extent of contamination. Laboratory Data Representativeness Representativeness in the laboratory is ensured by carefully following standard laboratory analytical methods and procedures, meeting sample holding times, specifying detection limits that are at or below regulatory standards, and analyzing method blanks to check for laboratory contamination. Sample results will not be considered representative if contaminants are detected in the method blanks, or if the reporting limits are above the specified screening levels.

Representativeness Assessment Overall, 99.6% of the representativeness-related parameters met project requirements. Completeness Completeness is an assessment of the number of valid measurements obtained in relation to the total number of measurements planned for the successful achievement of the investigative objectives. Completeness is expressed as the percentage of valid measurements to the total number of measurements. The closer the numbers, the more complete the measurement process. Field Data Completeness Field completeness evaluates the number of valid measurements obtained from all measurements taken in the project. The intent of this program is to attempt to achieve a goal of 100 percent field completeness. Realizing that under normal conditions this goal may not be achievable, the field completeness goal for this program is 90 percent. This completeness goal is considered adequate to meet the DQOs for this Site based on prior consideration of PARCC parameters, the sampling plan designs, and data collection activities proposed for each medium. Laboratory Data Completeness Laboratory completeness evaluates the number of valid measurements obtained from all the measurements taken in the project. The intent of this program is to attempt to achieve a goal of 100 percent laboratory completeness. Realizing that under normal conditions this goal may not be achievable, the laboratory completeness goal for this program is 90 percent. Data Quality Summary AQS, Inc. 11 For this project no sample results were rejected, and all were deemed valid (with some data validation qualifiers) based on method and laboratory acceptance criteria. Some sample dilutions occurred due to elevated analyte concentrations and were not evaluated for usability.

Completeness for the project is considered acceptable and under control. Comparability Comparability is a qualitative parameter expressing the confidence with which one data set may be compared to another. Data sets will be compared only when precision and accuracy meet the specified acceptance criteria established in this section. Samples will be collected, and analytical results will be reported according to standard procedures and methods to ensure comparability with other similar data and results. The comparability goal will be achieved by following the SAP and the RAP, and the specific procedures contained therein, and by collecting and analyzing representative samples, specifying analysis by similar analytical procedures with comparable reporting limits and by reporting analytical results in appropriate and consistent units. Field Data Comparability Comparability is dependent upon the proper design of the sampling program and will be satisfied by ensuring that the SAP and RAP are followed and that proper sampling procedures are used. Data Quality Summary AQS, Inc. 12 For this project, field QC included sample duplicates only. Laboratory Data Comparability Analytical data will be considered comparable when similar sampling and analytical methods are used and documented. Similar QA objectives will be used throughout the project to ensure comparability. At the discretion of the Utah DERR, split samples may be collected for submittal to a third-party analytical laboratory to assist in evaluation of comparability. The frequency at which split samples are collected and analyzed will be specified by the Utah DERR following the receipt and approval of individual work plans for the project. For this project, both laboratories used standard analytical methods and standard units of measure. Reporting limits were consistent except when high analyte concentrations required sample dilution. Comparability Assessment Comparability for the project is considered acceptable and under control. Sensitivity Sensitivity is the capability of a method or instrument to discriminate between measurement response(s) representing differing levels of the variable of interest. The analytical laboratory, as part of their standard operating procedures, follows published, approved analytical methods which validate the methods including an evaluation of sensitivity, precision, and accuracy to ensure that the equipment can operate properly prior to sample analysis. Wasatch will review the laboratory detection and/or reporting limits to verify these limits are below applicable screening levels. Reporting limits used by the laboratory were typical for the methods used and it is assumed that these limits meet project requirements. All samples were run undiluted, at normal laboratory reporting levels, with the following exceptions: Sample(s) Analyte(s) Notes Qualifiers Chemtech 24F1419 Test Pit WCS Selenium, Total These analytes were reported as non-detect but were run diluted – elevating the detection limit.
