Underground tanks storing ________ are exempt from federal UST regulations.

Underground tanks storing ________ are exempt from federal UST regulations.

• A. Gasoline for vehicles
• B. Heating oil used on the premises
• C. Kerosene used off-site
• D. Diesel fuel for on-site generators

Answer: (B)

Underground storage tanks are regulated to prevent leaks that could contaminate groundwater, but there is a specific exemption for petroleum stored as heating oil used on the premises. When the oil is kept underground to heat the building and is consumed on-site, it falls outside the federal UST requirements. This is because the regulatory focus is on tanks that store fuel for vehicles or other off-site uses, which pose different or higher risks to water quality. Gasoline stored underground for vehicle fueling is a regulated scenario due to its use in powering transportation. Kerosene stored off-site isn’t used on the premises for heating and therefore doesn’t meet the on-site heating exemption. Diesel stored for on-site generators is typically regulated as storage for fuel used on-site. So, the heating oil kept underground for on-site heating is the exemption.
