An unprotected underground storage tanks life expectancy is 15 to 20 years of age. An aboveground tank that is not maintained can be deemed not fit for use after 3 years!!  Just like the roof on your house, underground and above ground fuel storage tanks eventually will wear out and need to be replaced. Though the State of New York does not regulate residential underground storage tanks under 1001 gallons, nor does the State of New Jersey regulate ANY residential tank, the decommissioning/replacement/maintenance of a tank, just like new siding or a roof, is something for which the homeowner should eventually budget. When taking action on your tank, there are solutions.
