shall not exceed .40.

Special Rules concerning Subdivision.
cerncial ulision.
(1.) A compartment may exceed the permissible length determined
by the rules of Regulation IV provided the combined length of each
pair of adjacent compartments to which the compartment in question
is common does not exceed either the floodable length or twice the
permissible length, whichever is the less.
