The OPS Petroleum Program regulates petroleum storage facilities with USTs (underground storage tanks) that hold 110 gallons or more and ASTs (aboveground storage tanks) that hold between 660 and 40,000 gallons. We also enforce NFPA (National Fire Protection Association) codes for ASTs that hold between 60 and 660 gallons or 40,000+ gallons when they are installed for retail and non-retail fueling.
