Underground Storage Tanks

LUST Trust Fund Support Contract, Utah Division of Environmental Response and Remediation (DERR)
Under this contract, SAGE investigated and remediated Leaking Underground Storage Tank sites throughout Utah.  Projects included preparing work plans and bid packages; preparing corrective action plans; conducting periodic ground water monitoring and reporting at sites; conducting site investigations; preparing free-product assessments and fate and transport evaluations; and implementing corrective action. 

Emergency Response, Premium Oil Company
Gasoline and diesel contamination from the former Cash Saver Service Station located on Main Street in Spanish Fork, Utah created a soil and ground water contaminant plume extending about 300 feet off-site. SAGE provided emergency response services to Premium Oil when petroleum-impacted soils were encountered during construction activities on Main Street near the site. We arranged for the storage of contaminated water generated by excavation dewatering, and designed and implemented a treatment system so that it could be discharged into an adjacent canal. SAGE provided oversight for the excavation contractor while coordinating with UDOT, Spanish Fork City, and the Utah Division of Environmental Response and Remediation. Under our direction, the UDOT contractor removed contaminated soils beneath Main Street in an area 100 feet wide by 160 feet long. Clean soils were segregated from underlying contaminated soils and reused on-site or taken off-site for use as fill materials, and contaminated soils were disposed of off-site.

Rod Harrison Property, Utah Division of Environmental Response and Remediation (DERR)
SAGE conducted a two phased subsurface investigation at this former service station in Duchesne, Utah, where leaking underground storage tank releases had previously been identified.  A total of 14 shallow soil borings and 13 shallow ground water monitoring wells were installed.  Soil and ground water samples were collected and analyzed for gasoline and diesel petroleum hydrocarbons.  Field and laboratory data were used to prepare ground water potentiometric surface maps, soil and ground water contaminant concentration contour maps, boring logs, cross-sections, and data summary tables.  Based on our analysis of the data, we determined subsurface soil and ground water conditions, defined the extent and magnitude of soil impacts from two release areas, and defined the resulting ground water plume which extended onto adjacent properties with occupied buildings.
