Any municipality which has authorized the acquisition or construction of all or of any part of a resource recovery facility and which has made an appropriation therefor may borrow temporarily upon the credit of the municipality such sum or sums as may be necessary for such acquisition or construction and may issue temporary notes for any such loan, including temporary notes issued in anticipation of the sale of bonds to be secured by the full faith and credit of the municipality, by the pledge of revenues to be derived from the operation of a resource recovery facility or by both the full faith and credit of the municipality and the pledge of revenues to be derived from the operation of a resource recovery facility. Each issue of any such temporary notes shall constitute a separate loan and may be for a period of not more than two years, except that any temporary notes issued in anticipation of the sale of bonds to be secured solely by the pledge of revenues to be derived from the operation of a resource recovery facility may be for a period of not more than four years. Such temporary notes may be renewed from time to time by the issue of other temporary notes, provided the period from the date of issue of the original notes to the date of maturity of the last renewal notes shall not be more than two or four years, as the case may be. The interest or discount on such temporary notes, including renewals thereof, and the expense of preparing, issuing and marketing the same, may be included as a cost of the acquisition or construction of a resource recovery facility and may either be borrowed temporarily under the provisions of this section or funded by the issue of serial bonds or notes under the provisions of this chapter. Temporary notes may be issued under the authority of this section in anticipation of proceeds to be derived from the sale of bonds notwithstanding that, at the time of issuing such temporary notes, the municipality has not actually authorized the issue of such bonds.
