Underground Storage Tank Maintenance Fee Annotations
Certain below-ground tanks are excluded from the definition of underground storage tank and/or exempted from the registration and fee requirements. Underground vaults are usually manufactured out of concrete and installed underground, like a cellar, for the purpose of containing petroleum storage tanks. Not all tanks contained in vaulted systems are excluded or exempted from the fee. However, a system which provides adequate secondary containment, permits visual inspection of the entire exterior surfaces of the tanks, including the underside and all connected piping, and which is inspected on a daily basis would meet the requirements for exemption if approved by the local permitting agency. 10/12/95.
