There is a Disability Administration Account within the Disability Fund. The director may, without at the time furnishing vouchers and itemized statements, withdraw from this account sums not to exceed in the aggregate an amount equal to three percent of the total disbursements made from the fund during the immediately preceding fiscal year to be used as a revolving fund where payment of compensation earned, traveling expense advances, or other cash payments are necessary. At the close of each fiscal year or at any other time, upon the demand of the Department of Finance, the money so drawn shall be accounted for and substantiated by vouchers and itemized statements submitted to and audited by the Controller.
