        there is a binding, written contract for the sale or exchange 
        of the bond. The credit rate for any day is the credit rate 
        which the Secretary or the Secretary's designee estimates will 
        permit the issuance of water conservation, reuse and efficiency 
        bonds with a specified maturity or redemption date without 
        discount and without interest cost to the qualified issuer.
            ``(4) Credit allowance date.--For purposes of this section, 
        the term `credit allowance date' means--

        case of a bond which is issued during the 3-month period ending 
        on a credit allowance date, the amount of the credit determined 
        under this subsection with respect to such credit allowance 
        date shall be a ratable portion of the credit otherwise 
        determined based on the portion of the 3-month period during

                    ``(B) Refinancing rules.--For purposes of paragraph 
                (1)(B), a qualified project may be refinanced with 
                proceeds of a water conservation, reuse and efficiency 
                bond only if the indebtedness being refinanced 
                (including any obligation directly or indirectly 
                refinanced by such indebtedness) was originally 
                incurred by a qualified borrower after the date of the

                amounts paid after the date of the enactment of this 
                section with respect to a qualified project, but only 
                if--

                        expenditure, the qualified borrower declared 
                        its intent to reimburse such expenditure with 
                        the proceeds of a water conservation, reuse and

                paragraph (1)(B), the proceeds of an issue shall not be 
                treated as used for a qualified project to the extent 
                that a qualified borrower or qualified issuer takes any 
                action within its control which causes such proceeds 
                not to be used for a qualified project. The Secretary 
                shall prescribe regulations specifying remedial actions 
                that may be taken (including conditions to taking such 
                remedial actions) to prevent an action described in the 
                preceding sentence from causing a bond to fail to be a 
                water conservation, reuse and efficiency bond.
    ``(e) Maturity Limitations.--
            ``(1) Duration of term.--A bond shall not be treated as a 
        water conservation, reuse and efficiency bond if the maturity 
        of such bond exceeds the maximum term determined by the 
        Secretary under paragraph (2) with respect to such bond.
            ``(2) Maximum term.--During each calendar month, the 
        Secretary shall determine the maximum term permitted under this 
        paragraph for bonds issued during the following calendar month. 
        Such maximum term shall be the term which the Secretary 
        estimates will result in the present value of the obligation to 
        repay the principal on the bond being equal to 50 percent of 
        the face amount of such bond. Such present value shall be 
        determined without regard to the requirements of subsection 
        (l)(6) and using as a discount rate the average annual interest 
        rate of tax-exempt obligations having a term of 10 years or 
        more which are issued during the month. If the term as so 
        determined is not a multiple of a whole year, such term shall 
        be rounded to the next highest whole year.
    ``(f) Limitation on Amount of Bonds Designated.--
            ``(1) National limitation.--There is a national water 
        conservation, reuse and efficiency bond limitation of

        allocate the amount described in paragraph (1) among qualified 
        projects in such manner as the Secretary determines 
        appropriate, except that the Secretary shall allocate the bond 
        limitation for the financing of qualified projects in as 
        geographically diverse a manner as practicable.
    ``(g) Credit Included in Gross Income.--Gross income includes the 
amount of the credit allowed to the taxpayer under this section 
(determined without regard to subsection (c)), and the amount so 
included shall be treated as interest income.

                issue are to be spent for 1 or more qualified projects

                borrowers, such binding commitment will be incurred

                diligence and the proceeds of such issue will be spent 
                with due diligence.
            ``(2) Extension of period.--Upon submission of a request 
        prior to the expiration of the period described in paragraph 
        (1)(A), the Secretary may extend such period if the qualified 
        issuer establishes that the failure to satisfy the 5-year 
        requirement is due to reasonable cause and the related projects 
        will continue to proceed with due diligence.

        within 5 years.--To the extent that less than 95 percent of the 
        proceeds of such issue are expended by the close of the 5-year 
        period beginning on the date of issuance (or if an extension 
        has been obtained under paragraph (2), by the close of the 
        extended period), the qualified issuer shall redeem all of the 
        nonqualified bonds within 90 days after the end of such period. 
        For purposes of this paragraph, the amount of the nonqualified 
        bonds required to be redeemed shall be determined in the same 
        manner as under section 142.
    ``(i) Special Rules Relating to Arbitrage.--A bond which is part of 
an issue shall not be treated as a water conservation, reuse and 
efficiency bond unless, with respect to the issue of which the bond is 
a part, the qualified issuer satisfies the arbitrage requirements of 
section 148 with respect to proceeds of the issue.
