SITE DESCRIPTION The site is an active gas station and convenience store located at 325 West Main Street in Hyrum, Utah. The site has two 12,000-gallon and one 8,000-gallon above ground storage tank (ASTs) in an earthen containment on the north end of the property. There are three dispensers under the canopy east of the convenience store. A site map is provided as Figure 1. METHODOLOGY Six borings were advanced on July 10, 2024, to evaluate if soil and groundwater had been impacted at the site. Three borings were advanced around the ASTs and a boring was advanced adjacent to each of the three dispensers. B-3 was placed on the west side of the ASTS at the fill port area. Figure 1 shows the locations of the borings. Borings were advanced to a depth of ten feet. Five-foot soil core samples were collected continuously from the direct push borings. A portion of the soil core was put in a zip-lock baggie to allow hydrocarbons to volatilize. The air in the zip lock baggie was then screened with a photoionization detector (PID). Laboratory samples were collected at the interval of the highest PID reading or from just above the groundwater table. The samples were submitted for laboratory analysis of MTBE, benzene, toluene, ethylbenzene, xylenes, naphthalene (MBTEXN), and total petroleum hydrocarbons-gasoline range organics (TPH-GRO) using EPA Method 8260 and TPH- diesel range organics (TPH-DRO) using EPA Method 8015. Groundwater was encountered at approximately 4.5-6.5 feet below grade (bg). A groundwater sample was collected from each boring using a peristaltic pump. The samples were submitted for laboratory analysis of MBTEXN and TPH-GRO using EPA Method 8260, and TPH-DRO using EPA Method 8015. Phase II ESA, Manning Short Stop, Hyrum, Utah Rockwell Solutions, Inc., 718 E. Bridger Lane, Elk Ridge, UT 84651 801-361-2930 rockwellutah@yahoo.com 2 RESULTS Soil Type Soil type was evaluated during the subsurface investigation by field analysis of soil samples. The native soil at the site consists primarily of sandy silt to five to nine feet bg. A sandy gravel layer is below the sandy silt layer to at least ten feet bg. Boring logs are attached. Soil Analytical Results Table 1 lists the analytical results of the soil samples collected during the phase II investigation. The laboratory analytical reports and chain-of-custody records are attached. Hydrocarbon concentrations in B-1 and B-3, adjacent to the ASTs exceeded Tier 1 levels. Concentrations exceeded Initial Screening Levels (ISLs) in the samples from B-2, adjacent to the ASTs, and B-5, adjacent to the southeast dispenser. Samples from B-4 and B-6, at the northeast and west dispenser were below all cleanup levels. Figure 2 shows the approximate extent of soil contamination based on the current data. The main area of contamination is on the west side of the ASTs, around the fill port area. Groundwater Analytical Results Table 2 lists the analytical results of the groundwater samples collected during the phase II investigation. The laboratory analytical reports and chain-of-custody records for soil samples are attached. All groundwater concentrations were below Tier 1 levels. Samples from B-1, B-3, B-5, and B-6 exceeded ISLs. Figure 3 shows the approximate extent of contamination based on current data. CONCLUSIONS AND RECOMMENDATIONS Based on laboratory analytical results and field observations, the site has been impacted by releases associated with the fuel system. Rockwell Solutions recommends that the impacted soil around the fill ports be removed and that monitoring wells be placed to define the extent of and monitor the natural degradation of groundwater contamination.

Abbreviations ND = Not detected at the corresponding Minimum Reporting Limit (MRL). 1 mg/L = one milligram per liter or 1 mg/kg = one milligram per kilogram = 1 part per million. 1 ug/L = one 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.
