After installing a replacement tank, or perhaps deciding that a fuel system is no longer needed, state and federal regulatory agencies require a petroleum storage tank be properly decommissioned and removed from service.


The regulations and process differ slightly for decommissioning an aboveground storage tank (AST) system and an underground storage tank (UST) system. With either, the residual fuel must be removed and the tank must be cleaned. USTs are required to be removed from the ground, rendered useless, and required environmental sampling and reporting completed to ensure the tank did not leak. There are special waivers typically granted to leave the an UST in place, however, financial cost savings is not one of them. ASTs can be left in place as long as it is clearly labeled that the tank is no longer in service.
