Upon its own motion or the motion of a party, the Commission may allow the submission of additional evidence. A party may file a motion for leave to submit additional evidence at any time prior to issuance of a final decision by the Commission. Such motion shall show with particularity that such additional evidence is material and that there were reasonable grounds for failure to previously submit such evidence. The Commission may adjust its time for issuing a final decision accordingly, unless the subject of the appeal is a temporary closure order.

(1) New and material evidence is now available that, despite the party's due diligence, was not available when the record closed;

(2) The final decision was based on an erroneous interpretation of law or there has been an intervening change in the controlling law; or

(3) A manifest injustice, clearly apparent or obvious on its face, will occur if the motion for reconsideration is not granted.

(b) A motion for reconsideration and accompanying brief shall be filed within 30 days of the date of the Commission's final decision and shall be served on all parties, limited participants, and intervenors, if any. A motion for reconsideration shall explain the circumstances requiring reconsideration.

(c) A party may file only one motion and accompanying brief for reconsideration.

(d) Opposition briefs shall be filed within 20 days after the motion is filed.

(f) The Commission shall issue a decision on reconsideration within 30 days of the filing of the reply brief or of the expiration of the time to file a reply brief, whichever is later. The Commission shall issue a brief statement of the reason(s) for its decision.

(g) If the Commission grants the motion, it may reverse or modify the decision, in whole or in part, from which reconsideration is sought or may remand to the Chair for further consideration.
