  (d) Nothing in this section precludes the agency, on its own motion or on motion of the administrative law judge, from modifying the decision to correct a mistake or clerical error. A modification under this subdivision shall be made within 15 days after issuance of the decision.
  (e) The agency shall, within 15 days after correction of a mistake or clerical error in the decision, serve a copy of the correction on each party on which a copy of the decision was previously served.
