(1) In light of the fluctuating amounts of state revenues that have been available for controlled maintenance purposes in the past, the general assembly hereby finds and declares that a stable, predictable, and consistent source of revenues for controlled maintenance projects will better allow the state to fund such projects on a timely basis and avoid higher replacement costs. In order to provide a consistent source of revenues, the general assembly hereby further finds and declares that it is appropriate to create a trust fund which will generate an annual amount of interest which will be dedicated to controlled maintenance.

(2) (a) There is hereby created the controlled maintenance trust fund, the principal of which shall consist of any general fund revenues appropriated or transferred thereto by law, moneys credited thereto pursuant to section 24-30-1310, and proceeds of leveraged leasing agreements deposited thereto pursuant to section 24-82-1003 (3). For the 1996-97 fiscal year and fiscal years thereafter, the principal of the trust fund may constitute all or some portion of the state emergency reserve established pursuant to section 24-77-104 and may be expended in any given fiscal year as provided in said section. The principal of the trust fund shall not be expended or appropriated for any purpose other than use as part of the state emergency reserve. The state treasurer may in the state treasurer's discretion deposit, redeposit, invest, and reinvest moneys accrued or accruing to the controlled maintenance trust fund in the types of deposits and investments authorized in sections 24-36-109, 24-36-112, and 24-36-113.

(b) Beginning September 1, 1994, and on September 1 of each year thereafter, the state treasurer shall certify to the general assembly the amount of interest actually earned on the principal of the trust fund during the previous fiscal year and shall also provide an estimate of the interest expected to be earned on such principal during the current fiscal year.

(c) Beginning with the 1996-97 fiscal year, the interest earned on the principal of the trust fund balance may be appropriated for controlled maintenance, as defined in section 24-30-1301 (4), as follows: Up to fifty percent of the amount of interest expected to be earned on the principal of the trust fund during the current fiscal year as estimated by the state treasurer and the amount of interest actually earned on the principal of the trust fund during the previous fiscal year as certified by the state treasurer, not to exceed a maximum of thirty-five million dollars in any fiscal year.

(d) The principal of the trust fund and any unappropriated interest earned on the principal of the trust fund at the close of any fiscal year must remain in the trust fund and may not revert to the general fund.
