Underground Storage Tanks

EEC is sensitive to the difficulties facing underground storage tank (UST) owners. We can supply owners with an assessment that addresses both the physical integrity and the regulatory status of the facility. We conduct subsurface soil investigations utilizing soil gas analysis and/or hollow stem auger drilling, and provide complete laboratory analysis. We define the appropriate clean-up measures and potential costs, and provide the engineering services required to remove and replace the leaking components; clean up contaminated soil or water; and restore the site to meet ADEQ standards.

Service Areas Include:

Permitting
Assessments
Monitoring Programs
Closure Plans

Project Experience:

UST Management, Fort Huachuca, Arizona

EEC has been responsible for UST compliance and overall operation and maintenance of Ft. Huachuca's USTs since 1993. Tasks have included notification and reporting of UST removals; the development and execution of work plans assessing subsurface soil and groundwater contamination from leaking USTs; the preparation and execution of work plans for remediation of impacted soil and groundwater; and repair, maintenance, and annual reporting on operational USTs through the use of a subcontractor. EEC removed more than 80 USTs from various facilities located on the post. We obtained regulatory closure on 47 LUST sites.

Katcher UST Soil and Groundwater Assessment and Free Product Removal, Tucson, Arizona

EEC provided oversight for the removal of USTs, and conducted soil and groundwater assessments to define the extent of petroleum-hydrocarbon contamination at a privately-owned gasoline station. We are currently removing hydrocarbons floating on the shallow groundwater body.

Assessment for UST Removals, Luke Air Force Base, Arizona

EEC performed a preliminary assessment of 50 UST facilities for subsurface petroleum hydrocarbon contamination prior to removal and decommissioning.

The Circle K Corporation, Southern Arizona

EEC prepared, managed, and conducted all phases of assessment and remedial action of leaking underground storage tank (LUST) contamination at 45 sites located in Southern Arizona. Tasks involved the coordination of drilling equipment and personnel, mobile laboratory services, health and safety compliance, negotiations with regulatory agencies, and report preparation.

Octopus Car Wash, Tucson and Phoenix, Arizona

EEC removed USTs at two facilities and performed four subsurface soil assessments at three facilities with LUST files. Two LUST cases in Tucson were closed following remediation. The Phoenix LUST site is under remediation using air sparging and soil vapor extraction.
