Site History and Current Land Use
This site is an active gas station located at 4391 West 3500 South in West Valley City.In March
2023,two 12000 gallon gasoline underground storage tanks (USTs)and one 12000 gallon diesel
UST were removed and four new tanks were installed.To accommodate the new tanks,the tank
basin had to be widened.Samples taken at the time of tank closure contained petroleum
constituents above Tier 1 clean up levels.
Approximately 1,365 tons of soil was removed during the tank basin expansion and
approximately 54,000 gallons of groundwater was removed from the tank basin through
dewatering for new tank installation.The groundwater was placed in frac tanks and treated using
air compressors and granular activated carbon filters.The treated water was placed back in the
excavation after the tanks were installed.
Tank observation wells were installed in the east and west ends of the new tank basin.
Approximately two months after new tank installation,on May 26,2023 Rockwell Solutions
collected groundwater samples from the two observation wells TB-W contained 0.015 ppm
benzene which is above Initial Screening Levels (ISLs).
Due to this,the site was resampled on October 25,2023 and all petroleum constituents were
below state established cleanup levels.
Water Right 59-929 is within 180 feet of the location of the release and water right 59-500 is
about 300 feet away.Both wells are used for irrigation.The site is not in a groundwater
protection zone.
Nature and Extent of Contamination
Soil and groundwater samples were collected in the tank basin during UST closure activities on
March 17,2023 which contained petroleum constituents above state established cleanup levels in
the groundwater.No soil contamination was present.
March 17,2023:
●GW-E contained 0.147 ppm benzene,which is above ISLs as well as 22.1 ppm TPH-
GRO and 732 ppm TPH-DRO both of which are above Tier 1.
●GW-W contained 0.122 ppm benzene as well as 8.33 ppm TPH-GRO and 7.6 ppm TPH-
DRO,all of which are above ISLs.
Tank observation wells were installed in the east and west ends of the new tank basin and
groundwater samples were collected again on May 26,2023.There were no petroleum
constituents above state established clean up levels in sample TB-E,however TB-W contained
0.015 ppm benzene which is above ISLs.
Due to the lingering contamination in TB-W the site was sampled once more on October 25,
2023 and all samples came back below ISLs.
Exposure Pathways:
Groundwater Ingestion Exposure Pathway:
This pathway is incomplete.Drinking water is not sourced from wells in the area.Although there
is a well 180 feet away it is used for irrigation.All petroleum constituents are below state
established standards.
Soil Leaching to Groundwater Exposure Pathway:
This pathway is incomplete.Samples indicate there is no soil contamination at this site.
Vapor Intrusion to Indoor Air Exposure Pathway:
This pathway is incomplete as all petroleum constituents are below state established cleanup
levels.
Vapor Intrusion to Outdoor Air Exposure Pathway:
This pathway is incomplete because the site is overlain with asphalt and as all petroleum
constituents are below state established cleanup levels.
Recommendation for No Further Action:
This site meets the Corrective Action Cleanup Standards Policy for UST sites at Utah UST Rule
R311-211.Further cleanup of this site is not warranted as the remaining contamination is not
likely to adversely affect human health and the environment as discussed above.

depths, and other information on all soil/groundwater samples taken for closure. The samples must be consistently identified by sample ID #
on the site plat, table, and lab analysis report.
Completed Facility Site Plat (Closure Notice) is attached.
The following must be included (enter the distance, and direction (N,S,E,W) from the area of contamination or, where applicable,
use OH for overhead, NP for not present):

Samples were properly: Collected Labeled Packaged Transported
Samples were in sight of the person in custody at all times or in a secured locked place.
I certify under penalty of law that the closure site assessment at this facility was conducted in accordance with 40 CFR 280.52, 40
CFR 280.72, and R311-205 U.A.C., and that any additional samples required by 40 CFR 280.52, 40 CFR 280.72 and R311-205-2(a)(1)
were properly collected.

Please explain any unusual circumstances that occurred during the site assessment or closure:
During enlargement of the tank basin for replacement tanks, 1,365 tons of soil were hauled to ET Technologies. Even though soil concentrations were less than
ISLs, odor in the soil prohibited hauling it to a clean fill.
Three full frac tanks (54,000 gallons) were filled with groundwater from the excavation during tank basin enlargement and tank replacement. The groundwater
was treated by passing it through granular activated carbon filters to remove hydrocarbons and then drained back into the excavation after placement of the
new tanks.
