Tank Management
Concord routinely performs the removal and or installation of above ground and below ground storage tank systems containing petroleum products, solvents, acids and chemicals. All of the work is accomplished in accordance with local, state and federal codes API and NFPA standards. Concord develops and strictly adheres to site-specific Health & Safety plans.
Tank removal:
Residual fuel is removed from the tanks. The tanks are cleaned and tested for explosive vapors prior to removal. The tanks are removed, rendered unfit for reuse and promptly transported to a properly licensed disposal facility. Concord issues a “Certificate of Storage Vessel Destruction” which certifies the proper removal, cleaning and disposal of your tank. Confirmatory soil samples are collected and analyzed to insure compliance with applicable regulatory standards. A comprehensive “Tank Closure Report” is generated and distributed to the tank owner and local fire marshal. Any contaminated soil encountered is removed and transported to a licensed treatment or disposal facility.
Tank installation:
Concord has constructed tank and piping systems ranging is size from a 275 gallon heating oil tank to a 3 million gallon water storage tank. Concord personnel hold certifications as authorized installers from the major fiberglass and steel tank manufacturers and the International Fire Code Institute. We have successfully completed the removal and replacement of underground fuel storage tank systems at numerous municipalities, service stations and private industry.

A Tank Management Project: Lime Rock Park, 1999 Concord was contracted to remove and replace the Lime Rock Park Racetrack fuel station. The fuel station is located within the racetrack pit area and supplies 4 different grades of fuel for the racecars. The excavation depth required to accommodate the new tanks, reinforced concrete ballast pad and ancillary piping was 15’ below the ground surface. Ground water in the area was encountered at 5’ below the ground surface. Soils within the work area were comprised of very sharp sand and gravel. The porosity of the soils and high ground water conditions prevented dewatering by pumping. Interlocking sheet piling was driven to a depth that intersected with clay soils underlying the sand & gravel. This isolated the excavation area from the ground water. Concord was then able to control the flow of ground water by pumping. A reinforced ballast pad was constructed and the new tanks and piping were installed. Dry conditions were maintained until the tanks were backfilled.
