Sec.  57.4505  Fuel lines to underground areas.



    Fuel lines into underground storage or dispensing areas shall be 

drained at the completion of each transfer of fuel unless the following 

requirements are met:

    (a) The valve at the supply source shall be kept closed when fuel is 

not being transferred.

    (b) The fuel line shall be--

    (1) Capable of withstanding working pressures and stresses;

    (2) Located to prevent damage; and

    (3) Located in areas free of combustible materials or in areas where 

any exposed combustible materials are coated with one inch of shotcrete, 

one-half inch of gunite, or other noncombustible material with 

equivalent fire protection characteristics.

    (c) Provisions shall be made for control or containment of the 

entire volume of the fuel line so that leakage will not create a fire 

hazard.
