Whenever the head of any state department, board, bureau, commission, or other agency deems it necessary to have a petty cash fund for the proper transaction of the business of the agency, a written application therefor shall be made to the comptroller setting forth the details covering the purposes and uses of and for the fund. The comptroller, before issuing a state warrant for that purpose, shall determine whether or not the business of the agency warrants the establishment of such a fund, and if the comptroller is satisfied that such a fund is necessary, the comptroller shall issue a state warrant to such agency for an amount as the comptroller shall determine, not to exceed the sum of $100,000, except that this limitation of $100,000 shall not apply to the University of Hawaii and the stadium authority.

The comptroller may prescribe such rules as the comptroller may deem necessary for the proper administration and accountability of these funds.
