Box 610 Meridian, ID 83642 Re: Confirmation Sampling Report Former Jacksons Food Stores #102, 666 N Main Street, Clearfield, Utah Facility ID: 3000098, Release ID: MIZ Dear Mr. Wright: In accordance with work plan MIZ-12, Rockwell Solutions collected confirmation soil samples at the above-referenced site. The Division of Environmental Response and Remediation requested the samples to evaluate release MIZ for closure. As requested, borings were installed at the following sample locations: RW-1, RW-3, RW-9, RW-22, and SW. Soil samples were requested at ten feet deep at RW-1 and RW-22 and twelve feet deep at RW-3, RW-9, and SW (a UST closure sample location). Figure 1 is a site map showing sample locations. On February 20, 2024, borings were installed at the designated locations. The former gas station had recently been demolished. The convenience store building and canopy and all pavement were removed. Direct Push Services was employed as the drilling contractor under the supervision of a Rockwell Solutions representative. Five-foot soil core samples were collected continuously from the direct push borings. The native soil at the site consists of a well-graded, fine to medium-grained sand from the ground surface to a depth of at least fifteen feet below grade. Boring logs are attached. Some gray staining of the soil was present in most of the borings near the groundwater table. 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). The sample at the designated depth was collected and submitted for laboratory analysis of MTBE, benzene, toluene, ethylbenzene, xylenes, naphthalene (MBTEXN) total petroleum hydrocarbons-gasoline range organics (TPH-GRO) using EPA Method 8260 and TPH-diesel range organics (TPH-DRO) using EPA Method 8015. Hydrocarbons were detected in the onsite samples (RW-1, RW-3, and SW), but all concentrations were below Tier 1 and Initial Screening Levels. Hydrocarbons were not detected in samples RW-9 and RW- 22. Table 1 lists the analytical results of the confirmation soil samples as well as all historical soil samples collected at the site for releases LVO and MIZ. Figures 2 and 3 show the locations of all 2 Rockwell Solutions Inc., 718 E Bridger Lane, Elk Ridge, UT 84651 801-361-2930 rockwellutah@yahoo.com historical soil samples. The laboratory analytical reports and chain-of-custody records for the confirmation soil samples are attached. The soil sampling confirms that hydrocarbon concentrations are below cleanup levels. Rockwell Solutions recommends that releases LVO and MIZ be closed. If you need additional information or have any questions, please contact me at (801) 361-2930. Thank you, David S.

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.
