In the event that a Compact member state withdraws from the Compact before June 30, 1994, any person in such Compact member state who has made voluntary contributions shall be entitled to a refund of such contributions, not to include any actual interest earned on such contributions. The department may, pursuant to section 303, impose additional fees on mandated contributors sufficient to provide the amount to be refunded. This refund shall be paid when such additional fees become available to the department.
