(e) Every AST which is installed after September 30, 1994 and used for the storage of Class IIIB liquids, excluding unstable liquids, shall be located in accordance with Table 3-5 of these regulations, except when located within a diked area or drainage path for a tank(s) storing a Class I or Class II liquid. When a Class IIIB liquid storage tank is within the diked area or drainage path for a Class I or Class II liquid, AST.31.3(b), (c), or (d) shall apply. (f) Spacing (Shell-to-Shell) between Any Two Adjacent ASTs, where one AST is installed after September 30, 1994, with tanks storing Class I, II, or IIIA stable liquids shall be separated in accordance with Table 3-7 in these regulations. For unstable liquids, the distance between tanks shall not be less than one-half the sum of their diameters.
