Removals (Commercial)

Similar to the UST abandonment's the first step in this process will be to prepare and submit 30 Day Notice of Intent to Close an UST System to NJDEP. The UST(s) to be removed will be registered (if necessary) and TSES will notify all applicable local Health Departments and municipal agencies of closure activity in writing.

The UST(s) contents will be pumped dry prior to any excavation. TSES then will excavate to top of UST(s), drain all lines back into tank and purge tank. Once purged, a combustible gas meter will be used to determine if the level of combustible gas in the UST(s) is within safe limits to cold cut and clean to Fire Department and Department of Transportation Standards. All liquids and sediment will be containerized for disposal and manifested according to Federal and State Guidelines.

Once cleaned, the UST(s) will be removed from excavated area following API 1604 Procedures. All post excavation confirmatory sampling will be performed by an individual from TSES certified by the NJDEP in Subsurface Evaluation

The cleaned UST(s) will then be cut, transported and disposed/scrapped. All scrap yard receipts to be provided to the client as proof of disposal. The excavation areas will be backfilled with Certified Clean Fill compacted in 24" Lifts to Grade and we will restore the disturbed area as required. TSES will then Prepare & Submit Site Investigation / Remedial Investigation to NJDEP.

Abandonments (Commercial)

The first step in this process TSES Prepares and submits the 30 Day Notice of Intent to Abandon the UST System to NJDEP. The UST(s) to be abandoned-in-place will be registered (if necessary). We then notify all applicable local Health Departments and municipal agencies of closure activity in writing. The local Fire Department will be informed of the activities and local permits obtained. The UST(s) contents will be pumped dry prior to any excavation.

TSES will then excavate to top of UST(s), drain all the lines back into tank and purge the tank. Once purged, a combustible gas meter will be used to determine if the level of combustible gas in the UST(s) is within safe limits to cold cut and clean to Fire Department and Department of Transportation Standards. All liquids and sediment will be containerized for disposal and manifested according to Federal and State Guidelines. Once cleaned, the UST(s) will be filled with concrete slurry.

The post-excavation confirmatory sampling is performed by an individual from TSES certified by the NJDEP in Subsurface Evaluation. All sampling and analysis will be performed in accordance with the NJDEP's Technical Guidance Document N.J.A.C. 7:26E. If contamination is encountered, additional sampling and analysis may be required. This additional sampling and analysis will incur additional charges.

We then restore the disturbed area as required up to grade only and begin to Prepare & Submit the Site Investigation/Remedial Investigation to NJDEP.
