A further requirement of the section 7(b)(3) exemption is that more
than 75 percent of the sales of the enterprise engaged in the wholesale
or bulk distribution of petroleum products (measured by annual dollar
volume) must be made ``within the State in which such enterprise is
located.'' This means that over 75 percent of the annual dollar volume
of sales must be from sales to customers within the same State in which
the enterprise is located. If 25 percent or more of its sales volume is
from sales to customers outside the State of its location, the
requirement is not met and the enterprise cannot qualify for exemption.
