((a)) ** Authority of Secretary of Energy** Subject to sections 8835 and 8836 of this title, the Secretary of Energy may commit to guarantee, and guarantee, against loss on up to 90 per centum of the principal and interest, any loan which is made solely to provide funds for the construction of a municipal waste energy project and which does not exceed 90 per centum of the cost of the construction of the project involved, as estimated by the Secretary on the date of the guarantee or commitment to guarantee.
((b)) ** Estimated project construction costs as determinative of revised amount of guarantee** In the event the total estimated costs of construction of the project thereafter exceed the total estimated costs initially determined by the Secretary of Energy, the Secretary may in addition, upon application therefor, guarantee, against loss on up to 90 per centum of the principal and interest, a loan for so much of the additional estimated total costs as does not exceed 10 per centum of the total estimated costs.
((c)) ** Terms and conditions** The terms and conditions of loan guarantees under this section shall provide that, if the Secretary of Energy makes a payment of principal or interest upon the default by a borrower, the Secretary shall be subrogated to the rights of the recipient of such payment (and such subrogation shall be expressly set forth in the loan guarantee or related agreements).
((d)) ** Termination, cancellation, or revocation, and conclusive nature of guarantee** Any loan guarantee under this section shall not be terminated, canceled, or otherwise revoked, except in accordance with the terms thereof and shall be conclusive evidence that such guarantee complies fully with the provisions of this chapter and of the approval and legality of the principal amount, interest rate, and all other terms of the securities, obligations, or loans and of the guarantee.
((e)) ** Payment to lender** If the Secretary of Energy determines that—
((1)) the borrower is unable to meet payments and is not in default,
((2)) it is in the public interest to permit the borrower to continue to pursue the purposes of such project, and
((3)) the probable net benefit to the United States in paying the principal and interest due under a loan guarantee agreement will be greater than that which would result in the event of a default,
((f)) ** Preconditions** A loan may not be guaranteed under this section unless the applicant for such loan has established to the satisfaction of the Secretary of Energy that the lender is not willing without such a guarantee to extend credit to the applicant at reasonable rates and terms, taking into consideration prevailing market rates and terms for loans for similar periods of time, to finance the construction of the project for which such loan is sought.
((g)) ** Payment of interest; tax consequences**
((1)) With respect to any loan or debt obligation which is—
((A)) issued after , by, or on behalf of, any State or any political subdivision or governmental entity thereof,
((B)) guaranteed by the Secretary of Energy under this section, and
((C)) not supported by the full faith and credit of the issuer as a general obligation of the issuer,
((2)) With respect to the amount of obligations described in paragraph (1) that the issuer would have been able to issue as tax exempt obligations (other than obligations secured by the full faith and credit of the issuer as a general obligation of the issuer), the Secretary of Energy is authorized to pay only to the issuer any portion of the interest on such obligations, as determined by the Secretary of the Treasury after taking into account the interest rate which would have been paid on the obligations had they been issued as tax exempt obligations without being so guaranteed by the Secretary of Energy and the interest rate actually paid on the obligations when issued as taxable obligations. Such payments shall be made in amounts determined by the Secretary of Energy, and in accordance with such terms and conditions as the Secretary of the Treasury shall require.
((h)) ** Fees**
((1)) A fee or fees may be charged and collected by the Secretary of Energy for any loan guarantee under this section.
((2)) The amount of such fee shall be based on the estimated administrative costs and risk of loss, except that such fee may not exceed 1 per centum of the maximum of the guarantee.
