BACKGROUND On the morning of January 21, 2025, a Reladyne fuel tanker was delivering diesel fuel to an aboveground storage tank (AST) at the Jason Howard Nielson Property, in Lynndyl, Utah and over filled the AST, releasing 75 gallons of diesel fuel to concrete and soil surrounding the AST. REMEDIAL ACTIVITIES Soil excavation activities at the site commenced and were completed on January 30, 2025. The petroleum-impacted soil excavation was guided largely by field observations of surface staining, petroleum hydrocarbon odors noted in soils, and field screening with an organic vapor monitor and total petroleum hydrocarbon Test Kits. Photographs of the excavation are attached as Appendix A. The diesel fuel-impacted soil was loaded by the excavator into two roll-off containers and transported by MP Environmental to the E.T. Technologies Soil Regeneration Site (SRS), in Salt Lake City, Utah for disposal. The final depth of excavation was approximately 4 to 6 inches. Groundwater was not encountered during excavation activities at the site. A total of 26.2 tons of soil was excavated into two roll-off boxes and disposed of at the E.T. Technologies SRS on January 31, 2025 and February 7, 2025. The non-hazardous waste manifests for the soil disposal are presented in Appendix B. On February 11, 2025, the excavation was backfilled and the area restored. CONFIRMATION SAMPLES On January 30, 2025, Wasatch Field Scientist, Ryan Panasy (Utah GW and Soil Sampler GS 1950), collected 13 confirmation soil samples as outlined on Figure 3. The soil samples were labeled North 1 through North 3 and Pad 1 through Pad 10. The soil samples were collected from the base of the excavation at 4 inches below original grade. Once the samples were collected with decontaminated hand tools and transferred with gloved hands to laboratory-supplied sample jars, the jars were properly labeled, a chain-of-custody form was completed, and the samples were placed into a cooler with ice. Wasatch Environmental Inc. Page 2 The soil confirmation samples were analyzed at Chemtech-Ford Laboratories, Sandy, Utah, a Utah- Certified laboratory benzene, ethylbenzene toluene, total xylenes and naphthalene (BTEXN) by U.S. Environmental Protection Agency (U.S. EPA) Method 8260D and total petroleum hydrocarbons as diesel range organics (TPH-DRO) by U.S.EPA Method 8015C. ANALYTICAL RESULTS The laboratory analytical report, including chain-of-custody documentation, is presented in Appendix C. As shown on the laboratory analytical report, the sample results were at or below laboratory minimum reporting limits for all analyzed compounds. Naphthalene in sample North 1 was reported at the reporting limit. CONCLUSIONS AND RECOMMENDATIONS The analytical results of the soil confirmation samples indicate that soil concentrations of diesel fuel sampled at the spill site were at or below the laboratory minimum reporting limits as well as below the Utah Initial Screening Levels. Therefore, no significant soil impact remains at the spill site and the area is in a condition that would be protective of human health and the environment. Wasatch recommends that the release be closed and issued a “No Further Action” letter.

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.
