held on the tax effective date by any person if
the aggregate amount of such liquid (deter-
mined separately for aviation gasoline and avia-
tion fuel) held by such person on such date does

tence shall apply only if such person submits to

GROUP.—The
term ‘‘controlled group’’ has the
meaning given such term by sub-

pears in such subsection.

tions prescribed by the Secretary, prin-
ciples similar to the principles of clause (i)

(6) OTHER LAWS APPLICABLE.—All provisions
of law, including penalties, applicable with respect to
the taxes imposed by section 4081 or 4091 of such
Code shall, insofar as applicable and not inconsistent
with the provisions of this subsection, apply with re-
