1. Except as otherwise authorized by subsection 2 of section 701.310, no person shall engage in or conduct lead-bearing substance activities without having successfully completed a department or United States Environmental Protection Agency accredited training program and without having been licensed by the department.

2. The department shall develop and periodically update lists of all licensed inspectors, contractors, supervisors, workers, and other persons who perform lead hazard inspection and abatement and shall make such lists available free of charge to interested parties and the public.

3. The department may restrict, revoke, suspend or deny any license at any time if it believes that the terms or conditions of such license are being violated or that the holder of, or applicant for, the license has violated any regulation of the department or any other state law or regulation, or any federal law or regulation, or the laws or regulations of other states. The restriction, revocation, suspension or denial shall be effective immediately. Any person aggrieved by a determination by the department to restrict, deny, revoke or suspend any license may request a hearing before the administrative hearing commission within thirty days of receipt of the notice of license restriction, revocation, suspension or denial. The licensure shall remain restricted, revoked, suspended or denied while the hearing is pending.

4. The director may issue an immediate cease-work order to any person who violates the terms or conditions of any license issued pursuant to any provision of sections 701.300 to 701.338 or any regulation promulgated pursuant to sections 701.300 to 701.338 if, in the best judgment of the director, such violation presents a health risk to any person.
