Cal. Public Utilities Code § 131120

(a) The agency imposing the retail transactions and use tax may borrow money in anticipation of the sale of bonds which have been authorized pursuant to this chapter, but which have not been sold or delivered, and may issue negotiable bond anticipation notes therefor and may renew the bond anticipation notes from time to time. However, the maximum maturity of any bond anticipation notes, including the renewals thereof, shall not exceed five years from the date of delivery of the original bond anticipation notes. (b) The bond anticipation notes, and the interest thereon, may be paid from any money of the agency available therefor, including the revenues from the tax. If not previously otherwise paid, the bond anticipation notes, or any portion thereof, or the interest thereon, shall be paid from the proceeds of the next sale of the bonds of the agency in anticipation of which the notes were issued. (c) The bond anticipation notes shall not be issued in any amount in excess of the aggregate amount of the bonds which the agency has been authorized to issue, less the amount of any bonds of the authorized issue previously sold, and also less the amount of other bond anticipation notes therefor issued and then outstanding. The bond anticipation notes shall be issued and sold in the same manner as the bonds. (d) The bond anticipation notes and the resolutions authorizing them may contain any provisions, conditions, or limitations which a resolution of the agency may contain.
