(1) The department may suspend or revoke any license or permit issued if it appears that the licensee no longer possesses the qualifications necessary for the issuance of a new license or permit. The department may suspend or revoke any license or permit if it appears that the licensee has violated any of the provisions of this chapter. Such suspension or revocation shall occur only after notice to the licensee and a reasonable opportunity granted such licensee to be heard respecting the grounds of the proposed suspension or revocation. The department may refuse to renew the license of, or to issue another permit to, any applicant who has failed to comply with any provision of this chapter.

(2) The department may modify the terms of a permit after issuance thereof if the licensee is first given notice and a reasonable opportunity for a hearing respecting the grounds for the proposed modification and if it appears to the department that it is necessary for the protection of the health or the property of any person to make the modification proposed.
