If an assistance group requests a state hearing under division (B) of section 5101.35 of the Revised Code not later than fifteen calendar days after the department of job and family services mails the assistance group a written notice of a sanction under section 5107.161 of the Revised Code, a county department of job and family services shall postpone imposition of the sanction until the date a final decision is rendered in the state hearing, unless the assistance group withdraws the request for the state hearing because the assistance group is satisfied with the results of a county conference.
