    Class IB. Liquids having flash points below 73 degrees F. (23 degrees C.) and having a boiling point at or above 100 degrees F. (38 degrees C.).

    Class IC. Liquids having flash points at or above 73 degrees F. (23 degrees C.) and below 100 degrees F. (38 degrees C.). See combustible liquids for Class II or III liquids.

    M.

    "Replacement" means the removal of an AST/UST system, all of the piping between a storage tank and the dispenser unit, or both followed by replacement with an AST/UST system.

    N.

    "Storage tank" means any vessel having a liquid capacity that exceeds 60 gallons, is intended for fixed installation, and is not used for processing (NFPA 30, 30A, 1993 edition).

    O.

    "Temporary closure" means taking an AST/UST system out of service for more than 90 days with the intention of returning the AST/UST system to service within 12 months of when service was first discontinued.

    P.

    "Temporary out of service" means the normal operation and use of the AST/UST system is deliberately, but temporarily, discontinued for 90 days or less.

    Q.

    "UST System" means underground storage tank or combination of storage tanks, including the underground pipes connected thereto, that are used to contain an accumulation of regulated substances the volume of which, including the volume of the underground pipes connected thereto, is ten percent or more beneath the surface of the ground.

    R.
