Nassau County is committed to protecting our groundwater from petroleum contamination. The proper closure of small underground petroleum tanks, such as heating oil tanks, can reduce that threat.

Oil Tank Removal

The goal of a removal is to prevent oil spills from a tank that may leak. First, any residual oil and sludge is removed The tank is then removed and all associated piping is removed or permanently cut and sealed. An inspection by the Department is conducted to determine if there was a release oil to the environment and that all piping has been removed or properly sealed. The Department is required to be notified of aboveground and belowground tank removals.
