It is the intent of the Legislature that the program carried out pursuant to this article shall be fully supported from the fees collected for providing BIG to patients with suspected infant botulism or other forms of botulism and that these fees be made available for expenditure by the state department as appropriated by the Legislature in the annual Budget Act. However, it is the intent of the Legislature that until June 30, 1999, the Legislature may appropriate in the annual Budget Act the funds necessary for the support of programs authorized in this article in excess of fee revenues collected. It is, further, the intent of the Legislature that these appropriations be provided as a loan from the General Fund to be repaid with interest to the General Fund over the subsequent five years with interest at the rate earned by moneys invested in the Pooled Money Investment Account.
