SUBJECT: UST Closure Documentation Report
Lotus Advantage Citywalk
2220 South 240 East
Ogden, Utah
Facility ID: 1200687
Release ID: OLA

Wasatch has collaborated with Pacific West to complete removal and soil excavation activities at the
Lotus Advantage Riverwalk construction site (Site), located at 2220 South 240 East in Ogden Utah.
During initial grading activities for the site redevelopment, two abandoned underground storage tanks
(USTs) were identified. This report documents the proper removal and disposal of the tanks, over-
excavation and disposal of petroleum-impacted soil, pumping and disposal of groundwater, and the
analytical results of closure and confirmation sampling of soil and groundwater. All final soil and
groundwater confirmation samples were below Utah Initial Screening Levels (ISLs). The signed Closure
Notice is attached as Appendix A.

BACKGROUND

The Site is currently being redeveloped with a residential apartment building. On July 22, 2024, two steel
USTs approximately 500 gallons and 1,000 gallons in capacity, were discovered along the northeast
portion of the Site as depicted on Figures 1 and 2. The owners contacted Pacific West to submit the
required Closure Plan to the Utah Division of Environmental Response and Remediation (DERR), who
assigned Facility Identification Number 1200687 and Release identification OLA to the Site.

TANK CLOSURE AND EXCAVATION ACTIVITIES

A Closure Notice was submitted to the Utah DERR on July 22, 2024, and approved on July 23, 2024. On
July 25, 2024, the two USTs located at the Site were properly cleaned, inerted, removed, and disposed of
off-site. See the submitted Closure Notice (Appendix A) for additional UST removal details.

The soil closure samples were analyzed at Chemtech-Ford Laboratories for methyl tertiary-butyl ether
(MTBE), benzene, toluene, ethylbenzene, xylenes, naphthalene (MBTEXN), volatile organic halides
(VOX), and total petroleum hydrocarbons as gasoline-range organics (TPH-GRO) by United States
Environmental Protection Agency (U.S. EPA) Method 8260D; total petroleum hydrocarbons as diesel-
range organics (TPH-DRO) by U.S. EPA Method 8015D; and total recoverable petroleum hydrocarbons
(TRPH or oil and grease) by U.S. EPA Method 1664B. Subsequent sample analysis was reduced to
reflect the identified contaminants, which were TPH-DRO and TRPH.

Certain samples were additionally analyzed for the volatile organic compound (VOC) and semi-volatile
organic compound (SVOC) petroleum hydrocarbon fractions. The laboratory analytical reports are
presented in Appendix B. The analytical results are summarized in Tables 1 and 2.

After the results of closure soil samples SS-1 through SS-4 were reviewed and the two samples from the
southern tank (SS-1 and SS-2) were identified as elevated above the Utah ISLs, additional soil
excavation activities were conducted and Confirmation Soil Samples OEX-5 @ 10’ through OEX-8 @ 10’
were collected on August 2, 2024, at locations shown on Figure 2. A groundwater sample, GW-01 UST
Basin, was also collected since the additional excavation exposed groundwater at a depth of 13 feet
below ground surface.

The soil and groundwater confirmation sample results are summarized in Tables 1 and 2. Upon receipt
and review of those soil sample results, which identified that concentrations of petroleum hydrocarbons
above the Utah ISLs were still present, Pacific West requested permission from the Utah DERR to
excavate additional soil. On August 6, 2024, the Utah DERR approved the request and issued an
“Excavate Petroleum Impacted Soils during Tank Removal” letter.

After additional soil excavation and removal occurred, confirmation soil samples OEX-12 @ 13’ and OEX-
13 @ 13’ were collected on August 9, 2024. After more additional soil excavation and removal activites,
confirmation soil samples SS-11R and SS-13R were collected on August 20, 2024, from locations shown
on Figure 2.

After analytical results from samples SS-11R and SS-13R were reviewed, the sampling map and results
tables were forwarded to the Utah DERR Project Manager for review. The DERR requested that four
additional floor samples be collected and analyzed for TPH-DRO and TRPH.

Final confirmation soil samples SS-11R-Floor@13’, SS-OEX 10 Floor @ 13’, SS-OEX-5 @13’, and SS-
OEX-9-Floor @ 13’ (shown on Figure 2) were collected on August 26, 2024, and the results were below
the laboratory reporting limits for TPH-DRO and TRPH.

Approximately 317.8 tons of petroleum-impacted soil was disposed of at the Moulding and Sons Landfill.
Waste manifests for the petroleum-impacted soil disposal are presented in Appendix C.

The groundwater sample GW-1 results were below the Utah ISLs. However, TPH-DRO and TPH-GRO
were not analyzed. The sample was fractionated for VOC and SVOC petroleum hydrocarbons and the
DERR Site Specific Cleanup Calculator spreadsheet did not indicate any completed exposure pathways.
Because a sheen was observed on groundwater in the excavation, a vacuum truck operated by Pacific
West was utilized on August 9, 2024, to extract a total of 1,909 gallons of petroleum-impacted
groundwater from the excavation. Pacific West transported the groundwater to Sump and Trap Cleaning
located in Salt Lake City for disposal. The waste manifest for the petroleum impacted groundwater
disposal is presented in Appendix D.

On August 9, 2024, after extracting groundwater, a second groundwater sample GW-2 was collected.
The results of the groundwater analysis were below the minimum reporting limit for all compounds (see
Table 2), therefore, also below the Utah ISLs.

CONCLUSIONS AND RECOMMENDATIONS

Pacific West properly removed two orphaned USTs from the Site and supervised the over-excavation and
off-site disposal of petroleum hydrocarbon-impacted soil and groundwater. The results of the final
confirmation samples indicate that the soil and groundwater at the Site are below applicable Utah ISLs.
No further corrective action or investigation is recommended. The release should be issued a letter of
“No Further Action” and granted regulatory closure.

Report Footnotes
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.
Flag Descriptions
J = Detected but below the Reporting Limit; therefore, result is an estimated concentration (CLP J-Flag).
J-LOW-C = Estimated low due to low recovery of CCV
J-LOW-L = Estimated low due to low recovery of LCS

Report Footnotes
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.
Flag Descriptions
B = Analyte is found in the associated blank as well as in the sample (CLP B-flag).
J = Detected but below the Reporting Limit; therefore, result is an estimated concentration (CLP J-Flag).
J-LOW-C = Estimated low due to low recovery of CCV
J-LOW-L = Estimated low due to low recovery of LCS

Report Footnotes
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.
Flag Descriptions
J-LOW-L = Estimated low due to low recovery of LCS
S-BN = Base/Neutral surrogate recovery outside of control limits. The data was accepted based on valid recovery of remaining two base/neutral surrogates.
