The Commission of Budget and Accounting, referred to as "commission," is hereby expressly authorized and empowered to utilize any funds appropriated or otherwise made available for such purposes to make allocations to state agencies to defray the expenses incurred by them in carrying out their assigned disaster or emergency assignments which have depleted their regular appropriation below a level which would prohibit them from carrying out their normally assigned duties, and to repair or replace any property or equipment damaged, destroyed or lost as a direct result of the unprecedented devastation wrought by the excessive rains and floods in the spring of 1979 to the State of Mississippi and to pay the cost of federal flood insurance premiums on state-owned property damaged or destroyed as a result of said flood.
