(1) The pay and expenses of troops ordered to state active duty shall be paid from any appropriation for preserving the public peace or from the pay and expenses of troops ordered out in aid of civil authorities. Payments shall be made upon prescribed forms of payrolls and vouchers, accompanied by copies of the order under which troops were acting, certified by the Adjutant General and approved by the Governor. In those instances where the payment will be made from the Department of Military Affairs annual appropriation, the payroll need not be approved by the Governor. The Adjutant General shall be the sole authority of pay for state active duty.
(2) An estimated cost for pay, allowances, and expenses shall be calculated by the Adjutant General as soon as possible after the troops are ordered to state active duty; and the Adjutant General shall request a release of moneys for such purpose.
(3) Notwithstanding s. 216.271, moneys for pay and allowances of the troops ordered to state active duty shall be deposited in the Emergency Response Trust Fund, which must be approved by the Chief Financial Officer and is subject to s. 17.58(2). The Department of Military Affairs shall administer the fund. Frequency of payments to such troops shall be at the discretion of the Adjutant General. The Department of Military Affairs shall present to the Chief Financial Officer audit documentation of such payments. The Department of Military Affairs shall maintain all employee records relating to payments made pursuant to this subsection and shall furnish to the Chief Financial Officer the information necessary to update the payroll master record of each employee.
(4) The fund balance remaining in the Emergency Response Trust Fund after a final accounting of all expenditures for pay and allowances of the troops shall be returned for deposit to the State Treasury within 45 days after the termination of state active duty of the troops, except that an operating balance in an amount mutually agreed upon by the Chief Financial Officer and the Department of Military Affairs shall be retained in the fund.
(5) Vouchers for expenditures other than such pay and allowances shall be presented to the Chief Financial Officer for approval and payment as prescribed by law.
