Heating oil storage tanks are often an overlooked and forgotten utility that’s part of your home or business; until it leaks. A Residential fuel oil tank or a commercial fuel oil tank, whether the underground version

You’ve decided to remove your underground oil tank or replace your current old above ground tank due to its age. You’ve also decided to continue with oil as the fuel to heat your home for several very convincing reasons.

Soil remediation is a serious matter. Soil contamination, specifically caused by petroleum products requiring oil spill remediation, can be created by a wide variety of sources: leaking storage tanks

Most Common Question

There are no New Jersey Department of Environmental Protection (NJDEP) regulations that require the removal of underground residential heating oil storage tanks that are not leaking. Homeowners should contact their Town to determine if there are any local regulations or ordinances governing the removal and/or replacement of underground residential heating oil storage tanks. Homeowners should be aware that as their underground tank ages, the likelihood that it will leak increases. Tanks that are leaking need to be promptly removed.

NJDEP does not recommend that tanks be replaced with another underground tank. The main disadvantage of an underground tank is that a leak may go undetected for some time. With an above ground tank, the likelihood of detecting a release before it becomes severe is much greater.
