SEC. 3. SAFEGUARDS AGAINST DEFICIT SPENDING OUT OF THE INLAND WATERWAYS 
              TRUST FUND AND HARBOR MAINTENANCE TRUST FUND.

    (a) Estimates of Unfunded Inland Waterways Authorizations and Net 
Inland Waterways Receipts.--Not later than March 31 of each year, the 
Secretary of the Army, in consultation with the Secretary of the 
Treasury, shall estimate--
            (1) the amount which would (but for this section) be the 
        unfunded inland waterways authorizations and unfunded harbor 
        maintenance authorizations at the close of the first fiscal 
        year that begins after that March 31; and
            (2) the net inland waterways receipts and net harbor 
        maintenance receipts at the close of such fiscal year.
    (b) Procedure if Excess Unfunded Inland Waterways Authorizations.--
If the Secretary of the Army determines with respect to the Inland 
Waterways Trust Fund or the Harbor Maintenance Trust Fund for any 
fiscal year that the amount described in subsection (a)(1) exceeds the 
amount described in subsection (a)(2), the Secretary shall determine 
the amount of such excess.
    (c) Adjustment of Authorizations if Unfunded Authorizations Exceed 
Receipts.--
            (1) Determination of percentage.--If the Secretary of the 
        Army determines that there is an excess referred to in 
        subsection (b) for a fiscal year, the Secretary of the Army 
        shall determine the percentage which--
                    (A) such excess, is of
                    (B) the total of the amounts authorized to be 
                appropriated from the Inland Waterways Trust Fund or 
                the Harbor Maintenance Trust Fund, as the case may be, 
                for the next fiscal year.
            (2) Adjustment of authorizations.--If the Secretary of the 
        Army determines a percentage under paragraph (1), each amount 
authorized to be appropriated from the Trust Fund for the next fiscal 
year shall be reduced by such percentage.
    (d) Availability of Amounts Previously Withheld.--If, after an 
adjustment has been made under subsection (c)(2), the Secretary of the 
Army determines with respect to the Inland Waterways Trust Fund or the 
Harbor Maintenance Trust Fund that the amount described in subsection 
(a)(1) does not exceed the amount described in subsection (a)(2) or 
that the excess referred to in subsection (b) with respect to the Trust 
Fund is less than the amount previously determined, each amount 
authorized to be appropriated that was reduced under subsection (c)(2) 
with respect to the Trust Fund shall be increased, by an equal 
percentage, to the extent the Secretary of the Army determines that it 
may be so increased without causing the amount described in subsection 
(a)(1) to exceed with respect to the Trust Fund the amount described in 
subsection (a)(2) (but not by more than the amount of the reduction).
    (e) Reports.--Any estimate under subsection (a) and any 
determination under subsection (b), (c), or (d) shall be reported by 
the Secretary of the Army to Congress.
