It is currently used by Salt Lake City’s Police Department as a training facility and the Fire Department for equipment storage. Exhibit 1 (Appendix A) presents a topographic map of the area. Exhibit 2 is a site diagram that indicates the approximate location of the investigation area in relation to the site. 1.2 Project Background Exhibit 3 displays historical sample locations from previous investigations conducted from 1993 to 2013 in the vicinity of the former underground storage tanks (USTs) located on the property. Table 1 (Appendix B) presents a summary of the results of the soil samples collected from those sampling points, and Table 2 (Appendix B) presents a summary of the results of the groundwater samples collected from those sampling points. Four 10,000-gallon USTs (2 gasoline USTs and 2 diesel USTs) were removed from the site in 2011. Exhibit 4 displays the UST closure sample locations and Table 3 (Appendix B) presents the results of the soil and groundwater samples collected during the removal event. Soil and groundwater samples collected by IHI in 2013 (Exhibit 3; Table 1 and Table 3) identified soil and groundwater impacts above screening levels surrounding the former tank pit after tank removal. A corrective action plan was developed to address the petroleum-impacted soils and groundwater remaining in the vicinity of the former UST tank pit. The selected approach included removal of the impacted soils for off-site disposal and removal of impacted groundwater from the open excavation, followed by a limited application of chemical oxidation reagents to treat residual petroleum-impacted groundwater within the excavation area prior to backfilling. IHI conducted the Groundwater Monitoring Report Fleet Management Yard ■ Salt Lake City, Utah November 5, 2015 ■ Terracon Project No. AL137118B Responsive ■ Resourceful ■ Reliable 2 site work following the DERR-approved Work Plan IEQ-15. The Petroleum-Impacted Soil Excavation Report (Terracon; November 20, 2014) documented the implementation of the Work Plan IEQ-15 during January and February 2014. Exhibit 5 and Exhibit 6 display the soil and groundwater sample collection locations. Table 4 presents a summary of the results of the soil samples collected from those sampling points, and Table 5 presents a summary of the results of the groundwater samples collected from those sampling points. Following approved Work Plan IEQ-16 (IHI; February 26, 2015), IHI installed six new groundwater monitoring wells (T-1 through T-6; Exhibit 7) and conducted one quarterly groundwater sampling event (IHI; May 18, 2015) to document the concentrations of petroleum hydrocarbons remaining in the area following the Corrective Action event. Based on the results of the first groundwater monitoring event, concentrations of dissolved petroleum hydrocarbons were identified above groundwater screening levels at the site, and the extent of impacts was not defined. Work Plan IEQ-17 (IHI; May 18, 2015) was developed to further define the extent of impacts in the vicinity of the former tank pit, as well as conducting additional post-corrective action groundwater sampling. The Work Plan was designed to install four additional monitoring wells at the site to further define the extent of groundwater impacts and collect soil samples during the installation of the wells to further define the extent of soil impacts. This report documents the results of the installation of the four additional monitoring wells, the analytical results from the soil samples collected during monitoring well installation, as well as the analytical results from two rounds of groundwater sampling conducted at the site. 1.3 Scope of Work The objective of the Work Plan was to further delineate soil and groundwater impacts in the vicinity of the former tank pit, as well as to conduct additional groundwater sampling events at the site. The project goal is to meet regulatory limits, less than Initial Screening Levels (ISLs) for unrestricted land use, and receive a “No Further Action” status for Release ID IEQ. 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.

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 soil boring and monitoring well installation activities were conducted on June 10, 2015, by Amy Findley, Utah UST Groundwater and Soil Sampler (#GS-1465), and David Jamison, Utah UST Groundwater and Soil Sampler (#GS-1710). The approximate boring locations, T-7 through T-10, are shown on Exhibit 7 (Appendix A). The borings were advanced using direct push drilling equipment. 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 Project Manager. Mechanized drilling equipment was cleaned using a high-pressure washer prior to beginning the project and before beginning the soil boring. Soil samples were collected continuously from the boring using a five- foot macro-core sampler. Soil cores were observed to document soil types, color, moisture content, and sensory evidence of environmental impacts. The soil samples were also field-screened using a portable Groundwater Monitoring Report Fleet Management Yard ■ Salt Lake City, Utah November 5, 2015 ■ Terracon Project No. AL137118B Responsive ■ Resourceful ■ Reliable 4 photoionization detector (PID) – Mini Rae 2000 PID to determine the potential presence of total volatile organic compounds (TVOCs). The subsurface soil types encountered during sample collection varied between borings but generally consisted of sands, clays, and gravels. PID readings ranging from non-detect to 6.0 parts per million (ppm). Groundwater was typically encountered at depths of approximately 9 to 10 feet below ground surface (bgs). Detailed lithological descriptions and PID readings are presented on the soil boring logs included in Appendix C. 2.2 Subsurface Soil Sampling One soil sample was collected from each boring from the interval displaying the highest impacts, or, if impacts were not observed, from the soil-groundwater interface. 2.3 Monitoring Well Installation The four borings were completed as permanent groundwater monitoring wells (T-7 through T-10), using the following procedures: n Installation of 10 feet of 2-inch diameter, 0.010-inch machine slotted PVC well screen with a threaded bottom cap; n Installation of 2-inch diameter, threaded, flush-joint PVC riser pipe to the surface; n Addition of pre-sieved 20/40 grade silica sand for annular sand pack around the well screen from the bottom of the boring to approximately 2 feet above the top of the well screen; n Placement of 2 feet of hydrated bentonite pellets above the sand pack; n Addition of cement/bentonite slurry to the surface; and, n Installation of a 7-inch diameter, circular, bolt-down, steel, monitoring well cover with a locking well cap inset in a flush-mount concrete well pad. 2.4 Groundwater Sampling On June 12, 2015, Mark Lilly (Utah UST Groundwater and Soil Sampler #GS-449) measured groundwater levels in the four newly installed monitoring wells T-7 through T-10. The wells were then developed by surging and removing groundwater until the well discharge was relatively free of fine-grained sediment. Prior to sample collection, each well was purged of a minimum of three casing volumes (or until the well ran dry and was allowed to recharge), using a new disposable bailer for each well. Groundwater samples were then collected directly into the appropriate laboratory-provided containers. On September 10, 2015, Jeff Kolmel (Utah UST Groundwater and Soil Sampler #GS-1592) returned to the site to collect additional groundwater samples from monitoring wells T-1 through T-10, as well as MW-4 and MW-5. Prior to sample collection, each well was purged of a minimum Groundwater Monitoring Report Fleet Management Yard ■ Salt Lake City, Utah November 5, 2015 ■ Terracon Project No. AL137118B Responsive ■ Resourceful ■ Reliable 5 of three casing volumes (or until the well ran dry and was allowed to recharge), using a new disposable bailer for each well. Groundwater samples were then collected directly into the appropriate laboratory-provided containers. 2.5 Gradient Measurement Based on the water level measurements and top-of-casing elevation data collected from monitoring wells T-1 through T-10, and MW-4 and MW-5 on September 10, 2015, the flow direction within the former UST basin was to the south- southeast (Appendix A; Exhibit 7). 3.0 LABORATORY ANALYTICAL METHODS The soil and groundwater samples were collected and placed in laboratory-prepared containers, labeled, 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). All samples were analyzed by laboratory test methods as appropriate for the type(s) of contaminants most likely to be associated with the former UST systems: methyl tert-butyl ether (MTBE), benzene, toluene, ethylbenzene, xylenes, and naphthalene (BTEXN), total petroleum hydrocarbons in the gasoline range (TPH-GRO), and total petroleum hydrocarbons in the diesel range (TPH-DRO). Samples were analyzed using the following methods: Analysis Sample Type No. of Samples Laboratory Method BTEXN, MTBE and TPH-GRO Soil 4 EPA Method 8260 TPH-DRO Soil 4 EPA Method 8015 BTEXN, MTBE and TPH-GRO Groundwater 12 EPA Method 8260 TPH-DRO Groundwater 12 EPA Method 8015 The executed chain-of-custody form and laboratory data sheets are provided in Appendix D. 4.0 DATA EVALUATION Please refer to Table 4 (Appendix B) for a summary of the laboratory analytical results for historical excavation confirmation soil samples and soil samples collected during this investigation. Please refer to Table 5 (Appendix B) for a summary of the laboratory analytical results for groundwater samples. Tables 4 and 5 include regulatory screening levels for comparative purposes. Groundwater Monitoring Report Fleet Management Yard ■ Salt Lake City, Utah November 5, 2015 ■ Terracon Project No. AL137118B Responsive ■ Resourceful ■ Reliable 6 4.1 Soil Sample Results Soil samples collected during the installation of monitoring wells T-6 through T-10 did not report petroleum compounds above ISLs. 4.2 Groundwater Sample Results Groundwater samples were collected from T-7 through T-10 in June. Analytical results reported dissolved petroleum hydrocarbons above the laboratory reporting limit in wells T-8 (TPH-DRO, MTBE), T-9 (TPH-DRO, TPH-GRO, MTBE), and T-10 (TPH-DRO), but below their respective ISLs. The concentration of benzene reported in T-8 was the only constituent to exceed an ISL. None of the groundwater concentrations reported exceeded Tier 1 screening levels. Groundwater samples were collected from T-1 through T-10, and MW-4 and MW-5 in September. Analytical results reported low concentrations of dissolved petroleum hydrocarbons present in all 12 wells sampled. Only wells T-3, T-4, T-6, T-8 and T-9, located in the immediate down-gradient direction of the excavation area, reported constituents above an ISL. Only concentrations of TPH-DRO and benzene exceeded the ISL, and no concentrations reported exceeded a Tier 1 screening level. The highest concentration of TPH-DRO was reported at 1.87 mg/L in T-6, and the highest concentration of benzene was 0.104 mg/L in T-3. 5.0 FINDINGS AND CONCLUSIONS Based on the results of this limited subsurface investigation, petroleum impacts to soil originating from the former tank pit south of the former tank basin were not reported above ISLs, and it appears that the extent of the remaining impacted soil exceeding ISLs have been removed or remediated. Based on the results of the two quarterly groundwater sampling events, it appears that dissolved petroleum hydrocarbons, specifically TPH-DRO and benzene, remain above ISLs south of the former tank pit.
