Facility History - Executive Summary
An orphan UST was discovered and removed during construction at the Wonder Block Development, an Ogden Redevelopment
Agency project, April 2024. Soil excavation work occurred, about 181 cubic yards, including test pit soil, and soil confirmation samples
are <ISL. Groundwater sampled at the UST excavation, GW-1, had sampling results with TPH-DRO less than Tier I, and other
chemicals of concern <ISL. Groundwater explorations with test pits showed that GW impacts are < ISL standard surrounding the
orphan UST, see TP-1,2,4,5,6,9 and 10, while increasing levels of TPH-DRO exist north, about ¶of the orphan tank area, with TP-3,
7, and 8, exhibiting TPH-DRO contamination > Tier I standards. The area of high diesel contamination in groundwater once contained
4-USTs formerly closed in place (1998), but later removed in 2018. The 4-USTs had soil sampled for the DERR Closure Plan work,
but no GW was sampled. DERR UST staff did issue a UST letter declaring no corrective action was needed at that time, Jan. 7, 1999.
I recommend No Further Action for the orphan UST site and to pursue GW impact investigations with a new Release ID for the former
4-USTs nearby.

Recommended Tier 1 Actions
All contaminant concentration levels are below ISLs or below Tier 1 screening levels and no receptors are within the critical
distances. Recommendation - No further action.
Tier 1 criteria (contaminant concentration and/or distance to receptors) are exceeded at the site.
Recommendation - See attached supplemental information worksheet.
