Where the deputy commissioner has found that the claimant is eligible and that there is no operator responsible for the payment of benefits, the deputy commissioner shall issue a proposed decision and order including findings of fact and conclusions of law as required by 725.418 and authorize the payment of benefits. The claimant shall have 30 days after the date of issuance of the proposed decision and order within which to reject any or all of its terms. If the claimant does not reject the proposed decision and order, either in whole or in part, within this 30-day period, it will become final and effective. If for any reason the claimant rejects a proposed decision and order, the deputy commissioner may take such action as is appropriate including adjustment of the benefits to the level authorized by the uncontested portion of the proposed decision and order, if appropriate.
