For the purpose of carrying out this chapter, the Director of Finance may, by executive order, authorize the withdrawal from the General Fund of amounts not to exceed the amount of the unsold bonds which the committee has authorized to be sold for the purpose of carrying out this chapter.

The amounts withdrawn shall be deposited in the fund and shall be disbursed by the department or the board in accordance with this chapter. Any money made available under this section to the department or the board shall be returned to the General Fund from money received from the sale of bonds. The withdrawals from the General Fund shall be returned to the General Fund with interest at the rate which would have otherwise been earned by those withdrawals in the Pooled Money Investment Fund.
