Underground Storage Tank Closure
Closing an underground storage tank (UST) involves safely and permanently taking the tank out of service to prevent potential environmental hazards such as soil and groundwater contamination. The specific steps for closure can vary depending on regulatory requirements, the type of tank, and the stored materials. Here is a general guide to UST closure:
- Understand and comply with local, state, and federal regulations governing UST closure. Different regions may have specific requirements that dictate the closure process.
- Conduct a thorough site assessment to determine the current condition of the UST, potential soil and groundwater contamination, and the need for remediation.
Notification and Permits:
- Notify the appropriate regulatory authorities and obtain any necessary permits for UST closure. Some jurisdictions may require advance notification and approval before starting the closure process.
- Remove all remaining product and residues from the tank. Properly dispose of or recycle the removed material according to regulations.
Inert Material Filling (Closure-in-Place):
- If closure-in-place is permitted, clean the tank and fill it with an inert material such as sand, foam, or slurry. This prevents future use of the tank and helps maintain its structural integrity.
Tank Removal (Closure-by-Removal):
- If closure-in-place is not an option or if the tank is damaged, the UST may need to be removed. Excavate the tank, ensuring proper safety measures are in place. Transport the tank to an authorized disposal facility.
Soil and Groundwater Remediation:
- If contamination is detected during closure activities, remediation may be necessary. This can include soil excavation, treatment, and groundwater monitoring to ensure that any contaminants are properly addressed.
- Collect soil and/or groundwater samples to verify that the closure activities have effectively removed or treated any contaminants. Ensure that the site meets closure criteria established by regulatory authorities.
- Prepare a comprehensive closure report documenting all activities performed during the closure process. Include site assessment results, closure-in-place or tank removal details, remediation efforts, and verification sampling data.
- Submit the closure report to the relevant regulatory authorities for review and approval. Obtain closure certification once the authorities confirm that the closure has been conducted in accordance with regulations.
- Maintain detailed records of the closure process, including notifications, permits, assessments, sampling results, and regulatory approvals. These records may be required for future inspections or audits.
It’s crucial to involve qualified professionals with experience in environmental remediation and compliance with UST regulations to ensure that the closure process is conducted effectively and in accordance with applicable laws. Regular communication with regulatory agencies throughout the process is essential for a successful UST closure.
