Underground Storage Tank Removal

Underground storage tanks — particularly old fuel tanks at former service stations, industrial sites, and residential properties — represent a significant liability risk. Tetra handles the full removal process from permitting to regulatory closure.

Our team coordinates all required permits, supervises excavation and tank extraction, collects soil and groundwater samples to assess contamination, and manages proper disposal of the tank and any impacted materials. We then prepare the closure report and interface directly with state regulators.

If contamination is identified during removal, we can immediately transition to a Phase II investigation or remediation program — keeping your project on schedule and minimizing delays.
