Box 144840 195 North 1950 West Salt Lake City, Utah 84114-4840 Attn: Leigh Anderson P: (385) 391-8144 E: kanderson@utah.gov Re: December 2024 Groundwater Sampling Results Lelis Transmissions, VCP Site 128 845 South Main Street, Salt Lake City, Utah Terracon Project 61237399 Dear Ms. Anderson: This correspondence documents completion of an additional round of groundwater sampling at the Lelis Transmissions VCP site (VCP Site 128). This sampling event was conducted as outlined in the VCP-approved workplan dated December 14, 2024. GROUNDWATER MONITORING – DECEMBER 2024 Groundwater sampling was conducted on December 19, 2024 using the standard operating procedures (SOPs) detailed in the approved Quality Assurance Project Plan (QAPP) dated July 2, 2024. The sampling event included measurement of groundwater elevations and collection of samples for analysis from the five existing monitoring wells (MW-1, MW-4, MW-5, MW-6, and MW-7). Samples were collected using the same methodology (SOP Number 12, provided in Appendix B of the approved QAPP) as was used in previous sampling events. One field duplicate sample (MW-13, a duplicate sample from monitoring well MW-4) was also collected. Representatives of the VCP were onsite to observe the sampling activities. December 2024 Groundwater Sampling Lelis Transmissions | Salt Lake City, Utah February 17, 2025 (Revised April 7, 2024) | Terracon Project 61237299 2 LABORATORY ANALYSES The samples were delivered under standard chain-of custody protocols to an independent Utah-certified analytical laboratory (Chemtech-Ford in Sandy, Utah). The groundwater samples (and field duplicate) were analyzed for the following: Total Petroleum Hydrocarbons -Gasoline Range Organics (TPH-GRO), EPA Method 8260 Volatile Organic Compounds (VOCs), Method 8260 Total Petroleum Hydrocarbons – Diesel Range Organics (TPH-DRO), EPA Method 8015 Oil & Grease/Total Recoverable Petroleum Hydrocarbons (TRPH), EPA Method 1664. Additionally, the workplan specified that the groundwater sample with the highest total petroleum hydrocarbon (TPH) concentration(s), if any TPH concentrations exceeded Utah Initial Screening Levels (ISLs), would be further analyzed for TPH fractionation. Based on these criteria, TPH-DRO fractionation (based on EPA Method 8270) was conducted on the MW- 6 sample, which reported the highest TPH-DRO concentration above its ISL. The MW-1 sample reported the highest TPH-GRO concentration, which was below the ISL. However, TPH-GRO fractionation (based on EPA Method 8260) was conducted on the MW-1 sample to provide additional insight into the nature of the site’s dissolved TPH-GRO. DATA EVALUATION The results from the December 2024 round of groundwater monitoring indicate a groundwater flow direction (at and adjacent to the site) to the southwest. This is consistent with the observed flow direction during the two previous sampling events (June 2022 and May 2024), when groundwater monitoring was conducted from the existing monitoring wells installed in June 2022. The attached Exhibit 1 shows the measured groundwater elevation gradient and pertinent site features. Laboratory analytical results are summarized in the attached Table 1. Dissolved concentrations of most analytes were below screening levels and typically also below laboratory reporting limits with several exceptions. The sample collected from the onsite well MW-1 reported a naphthalene concentration of 0.0239 milligrams per liter (mg/l), which is moderately higher than the EPA Commercial Vapor Intrusion Screening Level (VISL) of 0.0201 mg/l but well below the Utah ISL of 0.7 mg/l. The reported benzene concentration in the sample from well MW-6 was 0.0018 mg/l, which is above the EPA Residential VISL but below the drinking water Maximum Contaminant Level (MCL). The reported concentrations of TPH-DRO were at or above the ISL of 1 mg/l in all samples except for the sample from well MW-7 (west of and across Main Street from the site). Results from the TPH fractionation analyses were evaluated using the Utah Department of Environmental Quality (UDEQ) Division of Environmental Response and Remediation (DERR) Site-Specific Cleanup Level (SSCL) Calculator. The maximum concentrations from the December 2024 groundwater analytical results were entered into the SSCL calculator for the December 2024 Groundwater Sampling Lelis Transmissions | Salt Lake City, Utah February 17, 2025 (Revised April 7, 2024) | Terracon Project 61237299 3 various C-ranges and associated petroleum-related VOCs. In cases where the constituents were not detected, the reporting limit (RDL) or minimum detection limit (MDL) was entered. The SSCL calculator was ran twice: once assuming residential land use, and a second time assuming commercial land use. Under both land use assumptions, none of the detected C-ranges (in either the gasoline or diesel ranges) were high enough to exceed the calculated SSCLs. For several PAH compounds that were not detected in the groundwater samples, the SSCL calculator indicated apparent exceedances of SSCLs, but these were artifacts of the calculator’s algorithms. The SSCL calculator requires input of the detection limits for “non-detect” values, which resulted in calculated SSCLs that are much lower than the detection limits for these compounds. These compounds were not actually detected in the samples, and there is no indication that these compounds are actually present. Additionally, these apparent SSCL exceedances for PAH compounds are for an exposure pathway (groundwater ingestion) that is incomplete at this site under current and future conditions, regardless of land use type. DATA QUALITY ASSESSMENT All laboratory analytical data were subject to internal reduction and validation prior to external release of the data. Following receipt of the laboratory analytical results by Terracon, the data were reviewed to evaluate compliance with Data Quality Indicators (DQIs). Documentation provided with the laboratory analytical results reports included case narratives; analytical data with minimum method detection limits (MDLs) and reported detection limits (RDLs) reporting limits listed for all analyses; surrogate recoveries for GC/MS analyses with laboratory control limits; chain-of-custody records; a quality control summary including method blanks, matrix spike/matrix spike duplicates (MS/MSD) with control limits, laboratory control samples, and duplicates (LCS/LCSD) with control limits, and application of data qualifiers where warranted. Assessment of the DQIs for Precision, Bias and Accuracy, Representativeness, Comparability, Completeness, and Sensitivity are presented in the following subsections. The laboratory results are assumed to be in control and the data is useable as presented unless specifically described below. Precision Precision was evaluated on the basis of relative percent difference (RPD) as a measure of reproducibility between LCS/LCSD pairs and MS/MSD pairs (analytical precision) and between field samples and field duplicate samples (field precision). The RPD is calculated to evaluate precision using the following equation. RPD =𝑿𝟎−𝑿𝟎 ቀ𝑿𝟎+𝑿𝟎 𝟎ቁ 𝒙𝟎𝟎𝟎Where X1 and X2 are the reported concentrations of the samples being evaluated. December 2024 Groundwater Sampling Lelis Transmissions | Salt Lake City, Utah February 17, 2025 (Revised April 7, 2024) | Terracon Project 61237299 4 Analytical Precision A summary of the Quality Control assessment for analytical precision is presented below. Laboratory Set 24L1692 o The RPDs for the MS associated with 2-hexanone and n-butyl alcohol (Laboratory Batch BYL1057), the MSD associated with 2-hexanone, bromomethane, and methyl isobutyl ketone (Laboratory Batch BYL1014), and the MSD for 2-hexanone, cis-1,2- dichloroehthene, ethyl ether, and n-butyl alcohol (Batch BYL1057)were outside the laboratory’s control limits. As a result, these data points were qualified with a RPD- MSOut flag. The affected groundwater samples were non-detect for these analytes, and these analytes are not considered contaminants of concern at the site. It is not anticipated that the analytical precision issue will affect the conclusions of this report. The RPD between the MS and MSD for cis-1,2-dichloroethene (Batch BYL1057) was outside the established limits, resulting in a RPD-01 flag. The affected samples were all non-detect for these analytes. As a result, this is not expected to affect the usability of the data or conclusions of this report. Based on the results of the RPD analyses of the MS/MSD and LCS/LCSD samples and the evaluation provided above,analytical precision is considered within control for Laboratory Set 24L1692. Field Precision One field duplicate groundwater sample was analyzed for TPH-GRO, TPH-DRO, TRPH, and VOCs. A summary of the Quality Control assessment for field precision is presented below. Analytical results for original samples and field duplicate pairs that are less than five times the laboratory’s Reported Detection Limit (RDL) in the analytical reports were considered within control if the difference between the sample concentration and its duplicate was less than two times the RDL. When analytical results for the original sample and the field duplicate pairs are greater than five times the RDL, the duplicate pair was considered within control when the RPDs for the field duplicate pairs were within the QAPP’s control limits (50% for soil samples, 25% for groundwater samples). Laboratory Set 24L1692: One duplicate sample pair was run for VOCs and petroleum hydrocarbons. o VOCs and Petroleum Hydrocarbons in Groundwater (Table 1) Reported concentrations for VOCs and petroleum hydrocarbons in groundwater were all in control. Based on the results of the RPD analyses of the field duplicate sample pairs and the evaluation provided above,field precision is considered within control for Laboratory Set 24L1692. December 2024 Groundwater Sampling Lelis Transmissions | Salt Lake City, Utah February 17, 2025 (Revised April 7, 2024) | Terracon Project 61237299 5 Bias and Accuracy Bias and Accuracy were evaluated through a review of the method blanks, trip blanks, percent recoveries for LCS/LCSD, and percent recoveries for MS/MSD summaries provided by the laboratory. Method blanks and trip blanks were considered within control (i.e.,accuracy) if the constituents analyzed were less than the analytical method reporting limits. LCS/LCSD and MS/MSD analyses were considered within control if the percent recoveries were within the laboratory’s established limits (i.e.,bias). A summary of the Quality Control assessment for Bias and Accuracy is presented below. Laboratory Set 24L1692: o Accuracy—Method and Laboratory Blank: All analytes in the method blanks were less than the laboratory RDLs. o Accuracy—Trip Blank: All analytes in the trip blank were less than the laboratory RDLs. o Surrogate Recoveries: The surrogate recovery was in control. o Bias—LCS/LCSD Percent Recoveries:The LCS for 1,1,2-trichlorotrifluoroethane, 1,2,3-trichlorobenzene, 2-hexanone, 2-nitropropane, cyclohexanone, hexachlorobutadiene, and n-butyl alcohol (Batch BYL1014) were estimated low due to low recovery. A J-LOW-L qualifier was applied to this data. The affected samples were all non-detect for these analytes. As a result, this is not expected to affect the usability of the data or conclusions of this report. The LCS for 1,1,2-trichlorotrifluoroethane, 1,1-dichloropropene, 2-hexanone, bromomethane, carbon tetrachloride, chloromethane, cyclohexanone, dichlorodifluoromethane, hexachlorobutadiene, n-butyl alcohol, pentachloroethane, tetrachloroethene, trans-1,3-dichloroethene, trans-1,3-dichloropropene, trichlorofluoromethane, and vinyl chloride (Batch BYL1057) were estimated low due to low recovery. A J-LOW-L qualifier was applied to this data. The affected samples were all non-detect for these analytes. As a result, this is not expected to affect the usability of the data or conclusions of this report. The recovery for the LCS for 2-hexanone (Batch BYL1057) exceeded the upper acceptance limit. A HB flag was assigned to this data. The affected samples were all non-detect for this analyte. As a result, this is not expected to affect the usability of the data or conclusions of this report. Bias—MS/MSD Percent Recoveries:The MS for 1,1,2-trichlorotrifluoroethane, 2-hexanone, n-butyl alcohol, and n-butylbenzene (Batch BYL1014) were estimated low due to Matrix Spike recovery. A MS-Low qualifier was applied to this data. The affected samples were all non-detect for these analytes. As a result, this is not expected to affect the usability of the data or conclusions of this report. The MS for 2-nitropropane (Batch BYL1057) was estimated low due to Matrix Spike recovery.

A QM-4X flag was assigned to this data. Additionally, the MS recovery for methyl ethyl ketone and sec-butyl benzene (Batch BYL1057) was outside the acceptance limits but passed duplicate spike acceptance limits. The December 2024 Groundwater Sampling Lelis Transmissions | Salt Lake City, Utah February 17, 2025 (Revised April 7, 2024) | Terracon Project 61237299 7 affected samples were all non-detect for these analytes.

The MSD recovery for isobutanol, tetrachloroethene, and vinyl chloride (Batch BYL1057) was outside acceptance limits but passed duplicate spike acceptance criteria. A QM-12 flag was assigned to this data. The affected samples were all non-detect for these analytes. As a result, this is not expected to affect the usability of the data or conclusions of this report. Bias and Accuracy are considered within control for Laboratory Set 24L1692 with the minor exceptions listed above. Representativeness Representativeness is a qualitative parameter most concerned with proper design and execution of the sampling program to produce data that accurately and precisely represent environmental conditions. Selection of analytical methods, sampling methods, and locations representative of the media sampled were set forth in the workplan.Representativeness in the field was achieved by implementing the approved workplan and using appropriate sampling methods, sample containers, sample handling, and preservation methods.Representativeness in the laboratory was achieved by using the proper analytical procedures, meeting sample holding times, and analyzing and assessing laboratory QA/QC samples. Field Representativeness Sampling was conducted in general accordance with the approved workplan. Field Representativeness is considered within control. Laboratory Representativeness Sample MW-6 was analyzed for TPH-DRO Fractionation past its holding time (7 days for Method 8270), after results for the initial TPH-DRO analysis (method 8015) were available for decision purposes. However, the fractionation analysis is used for characterization and fingerprint purposes only, as no regulatory screening levels have been established for the fractionation portion of the analysis. As such, it is unlikely that this holding time excursion affects the usability of the TPH-DRO fractionation data. Representativeness is considered within control with the minor exceptions listed above. Comparability Comparability is a qualitative term expressing the confidence with which one data set can be compared to another. The comparability goal was achieved using standardized sampling procedures in accordance with the SAP and QAPP, use of standardized and approved laboratory analytical methods, and reporting the analytical results in appropriate and consistent units. Sampling was conducted in general accordance with the approved workplan. December 2024 Groundwater Sampling Lelis Transmissions | Salt Lake City, Utah February 17, 2025 (Revised April 7, 2024) | Terracon Project 61237299 8 Sample analyses followed the analytical methods listed in the workplan, equivalent approved methods, or variations of the listed methods. The units of measure reported by the laboratory were consistent with the units of measure used by the regulatory screening levels. The number of field duplicates specified in the approved workplan was at least 10% of the field samples for groundwater. The DQIs for Comparability were achieved. As such,Comparability was deemed acceptable. Completeness Completeness is the ratio of valid measurements to the number of planned measurements, expressed as a percentage, and the completeness goal for the project is 90%. The sampling program is deemed to meet the DQIs for valid measurements. The samples collected were submitted and analyzed by the laboratory according to the chain-of-custody. Additionally, the data collection followed the procedures and requirements as described in the approved workplan. The data are considered usable as qualified. One sample (MW-6) was analyzed for TPH-DRO Fractionation past the 7-day holding time for Method 8270. However, The analytical completeness for this sampling event still met the 90% goal. One groundwater duplicate was analyzed for five groundwater samples for petroleum hydrocarbons and VOCs or 20%, which exceeds the 10% goal for duplicates. The workplan detailed six groundwater samples (including field duplicate) for VOCs and petroleum hydrocarbons. All of these samples were collected. The sample completeness score exceeds the 90% project goal. The Completeness goal is considered met. Sensitivity Sensitivity refers to the capability of a method or instrument to discriminate between measurement responses representing different levels of the variable of interest. The sensitivity goal is for RDLs to be below comparative screening levels, which vary considerably by analyte and in value and applicability. Overall, the level of sensitivity was sufficient to allow the identification of soil and groundwater constituents above applicable regulatory screening levels. Laboratory Set 24L169: o Petroleum Hydrocarbons in Groundwater (Table 1): The RDLs were all less than the Utah ISLs and EPA MCLs (as applicable), for analytes reported as less than the RDL. VOCs in Groundwater (Table 1): The RDLs were all less than Utah ISLs, Utah Tier 1 screening levels, EPA MCLs, and EPA VISLs (as applicable), for analytes reported as less than the RDL. The exceptions to this were 1,2-dibroom-3-chloropropane, 1,2- December 2024 Groundwater Sampling Lelis Transmissions | Salt Lake City, Utah February 17, 2025 (Revised April 7, 2024) | Terracon Project 61237299 9 dibromoethane, 2-nitropropane, bromodichloromethane, carbon tetrachloride, chloroform, hexachloro-1,3-butadiene, and vinyl chloride. None of the groundwater samples had detections of these analytes above RDLs. These analytes are not considered contaminants of concern for this site. Hence, this sensitivity issue for groundwater samples is not anticipated to affect the conclusions of this report. With acknowledgement of qualified results for the analytes listed above, the analytical data are acceptable for their intended use to evaluate constituent concentrations compared to applicable regulatory screening levels. DISCUSSION Based on the results of the December 2024 round of groundwater sampling, the groundwater flow direction on and adjacent to the site was to the southwest, consistent with the observed flow direction during the two previous sampling events that have been competed since June 2022 when the existing monitoring well network was installed. During the May 2024 groundwater sampling event, none of the analyzed constituents were detected at concentrations above an ISL. However, during the December 2024 groundwater sampling event, ISLs were exceeded for TPH-DRO in four samples. The higher TPH-DRO concentrations observed in December 2024 are likely due to the fact that the silica gel treatment was not used for these analyses, whereas silica gel treatment was used during the May 2024 sampling event. The apparent increase in TPH-DRO concentrations may also be related to the relatively lower groundwater elevations in December 2024 (an average of approximately 0.6 foot lower) than in May 2024. Regardless, the results of the TPH fractionation indicate that none of the detected concentrations in the various C-ranges, in either the gasoline or diesel ranges, are high enough to exceed the calculated SSCLs for either residential or commercial land use1. Terracon anticipates using these results to inform the scope of a Remedial Action Plan (RAP), which will focus on targeted removal of subsurface contaminant source structures2 and impacted media after the existing building has been removed. The RAP will also reference activity and use limitations and other management controls including groundwater monitoring to be detailed in a Site Management Plan and implemented via an Environmental Covenant. 1 As stated on Page 3, for several PAH compounds that were not detected in the groundwater samples, the SSCL calculator indicated apparent exceedances of SSCLs, but these were artifacts of the calculator’s algorithms. The SSCL calculator requires input of the detection limits for “non-detect” values, which resulted in calculated SSCLs that are much lower than the detection limits for these compounds. These compounds were not actually detected in the samples, and there is no indication that these compounds are actually present. Additionally, these apparent SSCL exceedances for PAH compounds are for an exposure pathway (groundwater ingestion) that is incomplete at this site under current and future conditions, regardless of land use type. 2 Such structures will include the Oil Water Separator, sumps, drains, hydraulic lifts, and other relevant features.
