If your house has oil heat, this information applies to you. At the Nantucket Annual Town Meeting in 2019, new oil tank regulations were passed. Subsequently approved by the state, they are now in full effect. Before a property with oil heat is sold, the tank must be inspected by a licensed oil burner service technician to confirm that it is in compliance with the regulations. The compliance report is to be provided when the Nantucket Fire Department inspects for smoke and carbon monoxide detectors. The cost of each inspection is $50, paid by the seller of the property. There have been regulations regarding buried oil tanks in Massachusetts for many years. This new regulation seeks to add another level of safety by requiring double hulled tanks which will reduce the likelihood of an oil spill. See full regulation here.
