MARVIN MANDEL, Governor                      1171

the State, upon approval by the Board of Public Works, for the de-
sign and construction of one or more diked disposal areas and other
and appurtenant facilities to receive dredging spoil from the harbor
and the approach channels in the water and adjacent areas known
generally as the harbor of Baltimore City; and for acquiring land,
properties, facilities, structures, and options for these purposes and
in connection therewith, and providing generally for the issue and
sale of Certificates of Indebtedness evidencing such loan.

Sec. 6. And be it further enacted, That, until all of the interest
on and principal of any certificates issued under this Act have been
paid in full, there is hereby levied and imposed an annual State tax
on each $100 of assessable property at the rate to be determined in
the following manner: on or before May 1, 1970, and on or before
May 1, in each taxable year thereafter, the Board of Public Works
shall certify to the governing bodies of each of the counties and
Baltimore City the rate of State tax on each $100 of assessable prop-
erty necessary to produce revenue to meet all interest and principal
which will be payable to the close of the next ensuing taxable year
on all certificates theretofore issued or heretofore authorized by
resolution of the Board of Public Works to be issued and the govern-
ing bodies of each of the counties and Baltimore City shall forthwith
levy and collect such tax at such rate.

All matters committed by this Act to the discretion of the Board
of Public Works shall be determined by a majority of said Board.

Sec. 7. And be it further enacted, That, except as otherwise in-
dicated herein, moneys derived from the sale of Certificates of In-
debtedness authorized by this Act shall be used only for capital
improvements and for no other purpose. In determining whether an
expenditure represents a capital improvement, the Board of Public
Works shall be guided by the principle that a capital improvement is
an improvement the useful life of which shall be at least equal to
the life of the bonds or Certificates of Indebtedness by which it is
financed.

SEC. 8. And be it further enacted, That, if any portion (word,
sentence, paragraph, proviso or section) of this Act shall be held
invalid for any reason, the remaining provisions shall remain in
full force and effect, and such invalid portion shall be considered
severed and deleted from this Act.

Sec. 9. And be it further enacted, That this Act shall take effect
July JUNE 1, 1969.
