This no further action applies only to the specific Release Site OIR. This recommendation is based on the information contained in the file for this release. That information was supplied by you, your consultant, or another representative. The information submitted indicates that petroleum contamination of the soil remains from this release. The contamination is at locations that are not currently considered a threat to human health or the environment according to Utah Admin. Code R311-211. This evaluation is based on current land usage, exposure pathways, potential receptors and other site-specific risk characteristics. In the future, if changes to these characteristics create a threat to human health or the environment, additional corrective action may be required. If you have any questions regarding this matter, please contact Liberty Coe, the DERR project manager, at (801) 536-4100. Sincerely, Brent H.

The extent and degree of contamination has been fully defined and a No Further Action (NFA) review is hereby requested. Case file information justifying no further action includes the following: Due to a small landslide in August 2023, a temporary fuel system was in use. On September 5, 2023 approximately 1,500 gallons of diesel fuel spilled onto the concrete pad and adjacent compacted road while fuel was being transferred to the pup trailer at the temporary fueling station. This was caused by the operator inadvertently missing a step in when opening a vent valve during the unloading process. Kennecott Utah Copper assessed the site and initiated clean-up efforts immediately after the spill by removing approximately 50 tons of soil and applying a new road base. The contaminated soil was sampled and disposed of at a permitted Class III industrial landfill. Soil samples taken on November 9, 2023 confirm contamination is below Tier 1 clean up levels. The primary fuel station is in operation again. This fuel station includes secondary containment and underground piping within a vault system that will direct any spills to an additional large catch basin.
