Upon notification to all parties, the Agency Decisionmaker or Administrative Law Judge may take official notice of any fact or document not appearing in evidence in the record. Any party objecting to the official notice must file an objection within 10 days after service of the notice. If a Final Order has been issued, and the decision rests on a material and disputable fact of which the Agency Decisionmaker has taken official notice, a party may challenge the action of official notice in accordance with § 386.64.
