Storage Tank Services

Aging and leaking tanks and pipelines are a significant contributor to subsurface pollution throughout the country. SES offers preventative maintenance, inspection services, emergency repair, closure, and tank replacement, as well as site remediation, restoration and monitoring services.


We have inspected, repaired, closed, removed and recycled many hundreds of USTs and ASTs and their associated piping. At SES we understand compliance requirements and are well-versed in sampling and monitoring activities to ensure that we leave a safe and clean environment. We are also certified to install replacement ASTs as needed to modernize facilities and bring them into compliance.

Featured Projects

UST REMOVAL AND STRUCTURAL DEMOLITION - Fort Campbell, Kentucky
At the Army and Air Force Exchange Service Station, SES removed one 20,000 gallon regular gasoline UST, one 12,000 gallon mid-grade gasoline UST, and one 12,000 gallon super unleaded gasoline UST. We demolished the tanks' concrete pad, removed 900 linear feet of supply product piping, and removed and recycled the existing metal canopy shelter. Excavated soil was sampled and closure regulation procedures were followed.  We reused 1,100 cubic yards of compacted site soils, restoring the site to surrounding grade evaluations. Minor gasoline-impacted soils were characterized and properly disposed.

AST INSTALLATION AND UST REMOVAL at Building 6225 - Fort Campbell, Kentucky
We removed an 8,000-gallon diesel fuel UST and replaced it with a 1,500-gallon steel-lined ConVault AST complete with a leak detection system. All piping connecting the UST to the emergency generator that it supplied was removed, and new connections were made to the generator from the AST. Soil sampling at the excavation site confirmed clean removal and regulatory compliance.

TANK INVESTIGATION SERVICES - Fort Stewart, Georgia
SES first investigated contamination at a busy service station on Fort Stewart. Because of our success completing investigative work on time, within budget, and in compliance with EPA and state requirements, follow-on work has been performed at five separate maintenance facilities in the main cantonment area of Fort Stewart. We have installed and monitored wells, investigated, remediated or removed USTs and ASTs, and prepared and implemented Corrective Action Plans. Our staff has also removed multiple tanks at nearby Hunter Army Airfield.
