Oil To Gas Conversion In New Jersey
A conversion from oil to gas is the point where the construction code starts taking an interest in your old tank, even though it had no view on it the day before.
This page covers what the code asks of the tank during a conversion, and the current state of the rebates people expect to find.

Conversion Is The Moment The Code Applies
The Uniform Construction Code is not a retrofit code, which is why a tank sitting quietly in the ground for twenty years is nobody's problem in code terms. A conversion changes that, and the Department of Community Affairs uses conversion as its own worked example.
The bulletin states that an example of a circumstance involving the removal or abandonment of an underground storage tank where construction activity is taking place is a conversion from fuel oil to natural or LP gas, and that in this case code officials must ensure the tank is properly removed or abandoned in connection with the conversion.
There is one stated exception, which is where the owner can demonstrate a legitimate continued use of the tank.

The One Year Rule On A Disused Tank
Separately from the conversion trigger, the code sets a clock. Where a project leaves an underground tank out of service for one year, the bulletin cites International Fire Code section 5704.2.13.1.3 and requires the tank to be removed under section 5704.2.14 or abandoned in place under section 5704.2.13.1.4.
For an aboveground tank the wording is narrower. Out of service for one year, section 5704.2.13.2.3 requires that the tank shall be removed. No abandon in place option is offered for an aboveground tank.

Your New Tank Permit Should Not Be Held Up
A practical point that saves arguments at the counter. Where you are installing an aboveground replacement tank, the bulletin states a properly filed permit for that installation should not be withheld pending the filing of a separate demolition permit for the removal or abandonment of an underground tank which is not part of the contract for the new tank.
The two permits are separate pieces of work and the code treats them that way.

Where The Conversion Rebates Stand
The rebate people find when they search for this has closed. The South Jersey Gas Natural Gas Conversion Incentive Program applied to service contracts signed and submitted between 1 March 2024 and 31 December 2025, the programme period ended on 31 December 2025, and receipts had to be received before 31 January 2026.
It is also worth knowing what it covered even while it ran. The rebate applied to qualifying natural gas appliances, listed as stoves, ovens, dryers, fireplaces and generators. High efficiency equipment eligible under a separate energy efficiency rebate programme was expressly excluded, and nothing in the programme paid for removing or abandoning the oil tank.
Other New Jersey utilities run their own incentives and those change on their own schedules. We do not list figures for them here, because we have not been able to open and verify the utility's own published terms, and an out of date rebate figure is worse than no figure.

Fill And Vent Pipes Come Out Too
Whichever route the old tank takes, the pipework matters more than it sounds. The bulletin instructs inspectors to ensure that fill and vent pipes for aboveground tanks, particularly tanks in basements, and for underground tanks, are removed when the tank is removed or abandoned.
The reason given is concrete. Several accidents have occurred where fuel oil deliveries have been made where a fill pipe was left in place after the tank was removed, with oil pumped into a basement or into the ground and an expensive clean up following.

Conversion Questions
Do I have to remove my oil tank when I convert to gas?
The code requires the tank to be properly removed or abandoned in connection with the conversion. DCA Bulletin 95-1B names conversion from fuel oil to natural or LP gas as its example, and says code officials must ensure this happens. The stated exception is where the owner can demonstrate a legitimate continued use of the tank.
Can I leave the tank in the ground?
Abandonment in place is an accepted route for an underground tank, carried out under International Fire Code section 5704.2.13.1.4 and covered by the same demolition permit. An aboveground tank out of service for a year is required to be removed rather than abandoned.
Is there a rebate for converting from oil to gas?
The South Jersey Gas conversion incentive closed on 31 December 2025, with receipts due by 31 January 2026, and it rebated appliances rather than tank work. Check any other utility programme directly with that utility before relying on it.
Will the conversion rebate pay for the tank removal?
The South Jersey Gas programme did not. It listed qualifying appliances as stoves, ovens, dryers, fireplaces and generators, with no provision for removing or abandoning the oil tank.
Can the town hold up my new tank permit?
The bulletin says a properly filed permit for an aboveground replacement tank should not be withheld pending a separate demolition permit for an underground tank that is not part of the same contract.
What happens to the fill pipe?
It comes out, along with the vent pipe. The bulletin ties this to real incidents where oil was delivered into a basement or the ground because a fill pipe was left in place after the tank was gone.
