(a) The board may issue an official written reprimand of any person certified under this chapter as a disciplinary measure for a first violation of any requirement of this chapter.

(b) In addition, for any subsequent violation or for any serious first violation, the certificate of any person may be cancelled or revoked by the board of examiners, whenever it shall be established to the satisfaction of the board that the holder of the certificate has become unworthy of official endorsement by reason of violation of this chapter, intemperate habits, manifest incapacity, abuse of authority, or for other causes satisfactory to the board. Any person against whom charges are made shall have an opportunity to be heard in his or her own behalf. He or she shall have at least 30 days' notice in writing of the charges by the ex officio chairman, and, if the holder of a certificate is convicted on the hearing of the charge of violating any part of this chapter, his or her certificate shall be revoked by the board. The director, after a thorough investigation, may suspend the holder pending a meeting of the board of examiners and its final action.

(c) In addition to the reasons specified in subsection (b) for revocation of a certificate, a certificate holder may voluntarily surrender his or her certificate upon written request to the board for any reason acceptable to the board, and subsequent approval by the board. Pursuant to administrative rule, the board shall specify those reasons that are acceptable to the board for the voluntary surrender of a certificate.
