(b) The interest earned on the amount deposited in any reserve fund may be used for defraying the cost of the operations of the authority. Money in any debt service reserve fund shall not be withdrawn if it would reduce the amount of the fund to less than the amount which is pledged in the proceedings authorizing the issuance of the obligations secured by the debt service reserve fund, except for paying principal and interest on obligations maturing and becoming due and for the payment of which other monies of the authority are not available.
