Protect human health, safety and the environment by preventing releases of petroleum products from aboveground and underground storage tanks; and reduce, mitigate and eliminate the threats posed by petroleum products released from storage tanks.



The Petroleum Storage Tank Division (PSTD) comprises four departments: Accounting, Administrative, Compliance and Inspection, and Technical. The Division enforces state and federal regulations which pertain to petroleum storage tanks that contain antifreeze, motor oil, motor fuel, gasoline, kerosene, diesel and aviation fuel. The Fuel Inspectors check the calibration of gasoline pumps to ensure that customers are receiving the accurate amount of gasoline at each purchase. Inspectors also check octane levels and assist tank owners in proper release detection methods. The Division also administers the Petroleum Storage Tank Release Indemnity Fund, created by the Legislature in 1989 to help fuel storage tank owners meet a requirement for liability insurance for damage caused by leaking tanks.
