Facilities using underground (UST) or aboveground storage tanks (AST) must comply with strict regulatory requirements during closure or removal. Proper tank closure protects soil and groundwater and ensures compliance with federal and state programs.
O6 Environmental assists facility managers with closure planning, site assessment, remediation, and documentation to ensure safe and compliant tank removal.
Regulatory Requirements for Tank Closure
EPA UST regulations (40 CFR Part 280) and state programs require:
- Pre-closure notification to regulators
- Site assessment for soil and groundwater
- Proper tank removal and waste handling
- Comprehensive closure documentation
Noncompliance can result in fines, environmental damage, and liability for future contamination.
Site Assessment and Investigation
Excavation includes tank and piping removal, soil sampling, and sometimes groundwater testing. Analytical results determine if corrective action or additional remediation is required.
O6 Environmental provides services like industrial hazardous waste disposal to manage residual materials safely and according to regulations.
Documentation and Compliance Best Practices
Regulators require detailed records, including:
- Activity logs
- Sampling results
- Waste disposal documentation
Thorough documentation ensures inspection readiness and compliance defensibility.
