The State Controller may approve any general plan whereby:
(a)
Any expenditures which are a proper charge against money made available by the United States and deposited in the Vocational Rehabilitation Federal Fund may be paid in the first instance from any appropriation from the General Fund, expenditures from which are administered under the provisions of Sections 19010 to 19012, inclusive; and
(b)
The General Fund shall be reimbursed for expenditures made therefrom that are a proper charge against the Vocational Rehabilitation Federal Fund.
Such a general plan may provide for advance transfers from the Vocational Rehabilitation Federal Fund to the General Fund, based on estimates of such expenditures that will be subject to reimbursement from the Vocational Rehabilitation Federal Fund pursuant to such plan, and may provide for reimbursements to the Vocational Rehabilitation Federal Fund, when necessary.
Requests for reimbursement or transfer pursuant to such a plan shall be furnished to the State Controller in writing by the department, accompanied by such financial statements as the plan may provide. On order of the State Controller, the required amount shall be transferred in accordance therewith.
