The remaining portions of the site are covered with an asphalt parking lot. Exhibit 1 (Appendix A) presents the site location on a portion of the USGS 7.5-minute series topographic map. Exhibit 2 is a site diagram that indicates the approximate locations of the soil and groundwater sampling points in relation to pertinent site features. 1.2 Project Background The property is located at 845 South Main Street, Utah, and is occupied by the Lelis Transmissions shop. Terracon understands that a subsurface investigation was conducted on March 12, 2015, on the south-adjoining properties (857 and 865 South Main Street) as part of a potential property transaction. During the investigation, diesel contamination was discovered in the soil and groundwater on the adjoining properties at concentrations above regulatory limits. A petroleum release was reported to the Utah Department of Environmental Quality (UDEQ), Division of Environmental Response and Remediation (DERR) on March 25, 2015, and the DERR responded with a request to investigate the area of the former underground storage tank (UST) that was removed from the Lelis Transmission site in 1991. 1.3 Scope of Work Our scope of services involved conducting a Limited Site Investigation (LSI) to assess whether subsurface soil and/or groundwater beneath the site in the area of the former UST remain above regulatory limits and assess the level of impact to the site’s soil and groundwater. The LSI was conducted through a series of drilled borings to allow the collection of subsurface soil and groundwater samples for laboratory analysis for the type(s) of contaminants most likely to be present at each proposed boring location. Terracon’s LSI included advancement of three soil borings to groundwater to collect soil and/or groundwater samples. Our work scope was designed to assess the potential presence of benzene, toluene, ethylbenzene, xylenes, naphthalene (BTEXN), methyl t-butyl ether (MTBE); total petroleum hydrocarbons – diesel Limited Site Investigation Report Lelis Transmissions ■ Salt Lake City, Utah August 18, 2015 ■ Terracon Project No. AL157378 Responsive ■ Resourceful ■ Reliable 2 range organics (TPH-DRO), and TPH -gasoline range organics (TPH-GRO) to determine the impact to soil and groundwater at the site in the vicinity of the former gasoline UST and the adjoining building to the south. 1.4 Standard of Care Terracon’s services were performed in a manner consistent with generally accepted practices of the profession undertaken in similar studies in the same geographical area during the same time period. Please note that Terracon does not warrant the work of laboratories, regulatory agencies or other third parties supplying information used in the preparation of the report.

Limited Site Investigation Report Lelis Transmissions ■ Salt Lake City, Utah August 18, 2015 ■ Terracon Project No. AL157378 Responsive ■ Resourceful ■ Reliable 3 2.0 LIMITED SITE INVESTIGATION 2.1 Environmental Soil Borings Prior to drilling, the public utility location service (Blue Stakes) was notified at least 48 hours prior to drilling as required by law. In addition, a subcontracted private utility location service was used to identify and mark subsurface utilities in the area of each boring location. Terracon’s LSI field activities were conducted on May 28, 2015. As part of the approved scope of work, Terracon advanced three environmental soil borings at locations judged most likely to detect the presence of contaminants, if present. The approximate boring locations are shown on Exhibit 2 (Appendix A). All borings were advanced using direct-push drilling equipment. After completion of sampling at each boring, the boring was properly abandoned by backfilling with bentonite clay pellets, adding water to hydrate the bentonite clay, and restoring the surface with quick-set concrete patch as appropriate to match the surrounding area. Mechanized drilling services were performed by a State of Utah-licensed Monitoring Well Driller, using a direct-push drilling rig under the supervision of a Terracon Environmental Field Geologist. Mechanized drilling equipment was cleaned using a high-pressure washer prior to beginning the project and before beginning each soil boring. Soil samples were collected continuously from all soil borings, using a five-foot macro-core sampler. Soil samples were observed to document subsurface soil types, color, moisture content, and sensory evidence of environmental impacts. The soil samples were also field-screened using a portable photoionization detector (PID) – Mini Rae 2000 PID to evaluate the potential presence of total volatile organic compounds (TVOCs). The subsurface materials encountered generally consisted of fill material underlain by silts, clays, and gravels. Groundwater was encountered at depths of approximately 10 below grade surface (bgs). Detailed lithological descriptions and PID readings are included on the soil boring logs provided in Appendix B. 2.2 Subsurface Soil Sampling Terracon's LSI soil sampling program generally involved (unless otherwise specified) collecting and submitting for laboratory analysis one soil sample from each of the soil borings. Soil samples were collected from the zone exhibiting the highest potential for environmental impact based on field observations and PID readings. If no elevated PID readings were observed, the sample was collected from the capillary fringe zone, from the interval exhibiting a change in lithology, from the bottom of the boring, or from the interval of most likely environmental impact as determined in the field by the sampling professional. 2.3 Groundwater Sampling Groundwater samples were collected from each of the borings (converted to temporary groundwater sampling points using direct-push tooling with a retractable well screen), using a Limited Site Investigation Report Lelis Transmissions ■ Salt Lake City, Utah August 18, 2015 ■ Terracon Project No. AL157378 Responsive ■ Resourceful ■ Reliable 4 low-flow peristaltic pump. A section of dedicated polyethylene sample tubing was inserted into the drive point. The sample tubing was connected to a dedicated section of flexible polyethylene hose at the surface. This tubing was passed through a low-flow peristaltic hose pump used to develop the sampling point, as needed to reduce turbidity, and to purge the water column within the tool. Following probe development, the peristaltic pump was used to collect a groundwater sample directly into the appropriate laboratory-provided containers. 3.0 LABORATORY ANALYTICAL METHODS All soil and groundwater samples were collected and placed in laboratory-prepared glassware and placed on ice in a cooler. The samples and completed chain-of-custody forms were shipped via overnight courier to Environmental Science Corporation analytical laboratory in Mt. Juliet, Tennessee (a Utah-Certified Laboratory). The soil and groundwater samples collected from the borings were analyzed on a standard turnaround by laboratory test methods as appropriate for the type(s) of contaminants most likely to be encountered at each location. This included BTEXN, MTBE, TPH-DRO, and TPH-GRO. Samples were analyzed using the following methods: Analysis Sample Type No. of Samples Laboratory Method MTBE, BTEXN and TPH- GRO Soil 3 EPA Method 8260 MTBE, BTEXN and TPH- GRO Groundwater 3 EPA Method 8260 TPH-DRO Soil 3 EPA Method 8015 TPH-DRO Groundwater 3 EPA Method 8015 The executed chain-of-custody form and laboratory data sheets are provided in Appendix D. 4.0 LSI DATA EVALUATION Please refer to Table 1 (Appendix C) for a summary of the laboratory analytical results for all soil samples. Please refer to Table 2 (Appendix C) for a summary of the laboratory analytical results for all groundwater samples. The executed chain-of-custody form and laboratory data sheets are provided in Appendix D. Tables 1 and 2 also include comparative regulatory screening levels. For petroleum constituents that were detected, the regulatory screening levels included Initial Screening Levels (ISLs) and Tier 1 Screening Levels established by the DERR. Limited Site Investigation Report Lelis Transmissions ■ Salt Lake City, Utah August 18, 2015 ■ Terracon Project No. AL157378 Responsive ■ Resourceful ■ Reliable 5 4.1 Results for Soil Samples TPH-DRO was detected in the soil samples collected from soil borings B-1, B-2, and B-3 at a depth of 10 feet bgs at concentrations of 4,530 milligrams per kilogram (mg/kg), 2,810 mg/kg, and 3,820 mg/kg, respectively. The concentrations of TPH-DRO reported in these samples are above the ISLs of 500 mg/kg, but below the Tier 1 limit of 5,000 mg/kg. TPH-GRO was detected in the soil samples collected from soil borings B-1, B-2, and B-3 at a depth of 10 feet bgs at concentrations of 152 mg/kg, 179 mg/kg, and 209 mg/kg, respectively. The concentrations of TPH-GRO reported in these samples are above the ISLs of 150 mg/kg, but below the Tier 1 limit of 1,500 mg/kg. No other constituents were detected above laboratory reporting limits and/or applicable screening levels in any of the soil samples analyzed. 4.2 Results for Groundwater Samples TPH-DRO was detected in the groundwater samples collected from soil borings B-1, B-2, and B-3 at concentrations of 1,500 milligrams per liter (mg/L), 6.8 mg/L, and 9.5 mg/L, respectively. The concentrations of TPH-DRO reported in these samples are above the ISL of 1 mg/L, but below the Tier 1 limit of 10 mg/L, with the exception of the groundwater sample from B-1, which also exceeds the Tier 1 limit. TPH-GRO was detected in the groundwater sample collected from soil boring B-1 at concentrations of 7.2 mg/L. The concentration of TPH-GRO reported in this sample is above the ISL of 1 mg/L, but below the Tier 1 limit of 10 mg/L. No other constituents were detected above laboratory reporting limits and/or applicable screening levels in any of the soil samples analyzed. 5.0 FINDINGS AND CONCLUSIONS A petroleum release was reported to the DERR on March 25, 2015, at the adjoining property located south of the site. The DERR responded with a request to Lelis Transmissions to investigate the area of the former UST that was removed from the site in 1991. This LSI involved collecting subsurface soil and groundwater samples for laboratory analysis for the type(s) of contaminants most likely to be present at each area of concern. TPH-DRO was the contaminant with the highest concentrations identified in the soil and groundwater of this investigation. Lelis Transmissions previously had a gasoline, not a diesel UST, and that UST was closed by removal from the site in 1991. The highest TPH-DRO concentrations in the soil and groundwater at the site were identified at soil boring B-1, located immediately adjacent to the building located south of the site. The two soil borings advanced Limited Site Investigation Report Lelis Transmissions ■ Salt Lake City, Utah August 18, 2015 ■ Terracon Project No. AL157378 Responsive ■ Resourceful ■ Reliable 6 down-gradient and adjacent to the former gasoline UST location had levels of TPH-DRO and GRO in the soil above ISLs, but below Tier 1. The TPH-DRO levels were significantly higher than the TPH-GRO at this location as well. TPH-GRO and other gasoline constituents were not detected in the groundwater at concentrations above ISLs near the former UST. The observed distribution of contaminants appears to indicate an off-site contaminant source. It is Terracon’s opinion that the TPH-DRO and TPH-GRO contaminants identified during this investigation did not originate from the site, but possibly from the adjoining property to the south or from another location further up-gradient from the site. As such, Lelis Transmissions does not appear to be the responsible party and should not be required to conduct further investigation or corrective action at this time. Terracon recommends that if subsurface soils or groundwater that are disturbed during future construction activities exhibit staining, noxious odors, sheens, or any other abnormalities that suggest the potential presence of contaminants, then proper procedures should be followed with respect to worker health and safety, and any impacted soil or groundwater encountered should be properly characterized, treated and/or disposed in accordance with applicable local, state or federal regulations.

NATIONWIDE.GLOSSARY OF TERMS Abbreviations and Definitions SDG Sample Delivery Group. MDL Method Detection Limit. RDL Reported Detection Limit. ND,U Not detected at the Reporting Limit (or MDL where applicable). RPD Relative Percent Difference. (dry)Results are reported based on the dry weight of the sample. [this will only be present on a dry report basis for soils]. Original Sample The non-spiked sample in the prep batch used to determine the Relative Percent Difference (RPD) from a quality control sample. The Original Sample may not be included within the reported SDG. (S)Surrogate (Surrogate Standard) - Analytes added to every blank, sample, Laboratory Control Sample/Duplicate and Matrix Spike/Duplicate; used to evaluate analytical efficiency by measuring recovery. Surrogates are not expected to be detected in all environmental media. Rec.Recovery. SDL Sample Detection Limit. MQL Method Quantitation Limit. Unadj. MQL Unadjusted Method Quantitation Limit. Qualifier Description J The identification of the analyte is acceptable; the reported value is an estimate. J1 Surrogate recovery limits have been exceeded; values are outside upper control limits. J2 Surrogate recovery limits have been exceeded; values are outside lower control limits. J3 The associated batch QC was outside the established quality control range for precision. J6 The sample matrix interfered with the ability to make any accurate determination; spike value is low. J7 Surrogate recovery cannot be used for control limit evaluation due to dilution. 1 Cp 2 Tc 3 Ss 4 Cn 5 Sr 6 Qc 7 Gl 8 Al 9 Sc ACCOUNT:PROJECT:SDG:DATE/TIME:PAGE: Terracon - Draper AL157378 L767871 06/09/15 16:04 20 of 22 ACCOUNT:PROJECT:SDG:DATE/TIME:PAGE: Terracon - Draper AL157378 L767871 06/09/15 16:09 20 of 22 ONE LAB.
