Bonds issued under Section 15.1 shall be payable solely from the revenue derived from the operation of the land or facilities for which the bonds were issued. These bonds shall not in any event constitute an indebtedness of the conservancy district, within the meaning of any constitutional or statutory limitation. Each bond shall plainly state on its face that it has been issued under the provisions of Section 15.1 and 15.2 of this Act and that it does not constitute an indebtedness of the conservancy district within any constitutional or statutory limitation.
These bonds shall be sold in such manner and upon such terms as the board of trustees shall determine. If the bonds are issued to bear interest at the maximum rate authorized by the Bond Authorization Act, as amended at the time of the making of the contract, they shall be sold for not less than par and accrued interest. If the bonds are issued to bear interest at a rate of less than the maximum rate authorized by the Bond Authorization Act, as amended at the time of the making of the contract, the minimum price at which they may be sold shall be such that the interest cost to the municipality of the proceeds of the bonds shall not exceed the maximum rate authorized by the Bond Authorization Act, as amended at the time of the making of the contract, computed to maturity, according to the standard table of bond values.
With respect to instruments for the payment of money issued under this Section either before, on, or after the effective date of this amendatory Act of 1989, it is and always has been the intention of the General Assembly (i) that the Omnibus Bond Acts are and always have been supplementary grants of power to issue instruments in accordance with the Omnibus Bond Acts, regardless of any provision of this Act that may appear to be or to have been more restrictive than those Acts, (ii) that the provisions of this Section are not a limitation on the supplementary authority granted by the Omnibus Bond Acts, and (iii) that instruments issued under this Section within the supplementary authority granted by the Omnibus Bond Acts are not invalid because of any provision of this Act that may appear to be or to have been more restrictive than those Acts.
