Proceedings under this section may be initiated by any person, corporation, association, or public officer, or by the department by the filing of written charges with the department. Whenever the department seeks revocation or suspension of a certificate of an ambulance service or an advanced life support first response service, a copy of the charges shall be referred to the appropriate regional council for review and recommendation to the department prior to a hearing. Such recommendation shall include a determination as to whether the public need would be served by a revocation, suspension, annulment or limitation. If there is no appropriate regional council established, the state council shall make such determination and present to the department its recommendations. 3. No certificate shall be revoked, suspended, limited or annulled without a hearing. However, a certificate may be temporarily suspended without a hearing and without the approval of the appropriate regional council or state council for a period not in excess of thirty days upon notice to the certificate holder following a finding by the department that the public health, safety or welfare is in imminent danger. 4. The commissioner shall fix a time and place for the hearing. A copy of the charges and the recommendations of the appropriate regional council or state council together with the notice of the time and place of the hearing, shall be mailed to the certificate holder by registered or certified mail, at the address specified on the certificate, at least fifteen days before the date fixed for the hearing. The appropriate regional council may be a party to such hearing. The certificate holder may file with the department, not less than five days prior to the hearing, a written answer to the charges.
