(b) For each occurrence, a claimant must pay for otherwise eligible costs in the amount of the claimant's level of financial responsibility as set forth in section 2808.1 of this chapter. For each occurrence, the Board may reimburse from the Fund only eligible corrective action, regulatory technical assistance, and third party compensation costs in excess of a claimant's level of financial responsibility.

(c) If multiple or joint claimants file separate or joint claims against the Fund for the same occurrence, the Fund will require the claimants as a group to pay the amount of financial responsibility only once per occurrence. The required amount of financial responsibility will be equal to the amount of financial responsibility that would be required of the claimant in the lowest priority class.

(d) Reimbursement under section 2813.1, subdivision (c) of this chapter is available only to the extent that reimbursement for the earlier corrective action does not exceed the amount of reimbursement authorized by this section.

(e) No claimant may receive reimbursement from the Fund in any fiscal year which exceeds five percent of the total amount appropriated by the legislature for payment of claims for that fiscal year unless exempted by the Board pursuant to Health and Safety Code, section 25299.60, subdivision (c)(2).
