2. An individual is exempt from the licensing requirements of this chapter if the individual is installing an onsite wastewater sewage treatment system on the individual's premises for the individual's use.

3. The department shall establish rules for the issuance, expiration, and renewal of licenses.

4. The department may revoke or suspend a license issued under this chapter if: a. The licensee practices fraud or deception in obtaining the license or in the individual's performance of a licensed activity; b. Reasonable care, judgment, or the application of the licensee's knowledge or ability is not used in the performance of the licensee's duties; or c. The licensee violates a state or federal environmental law, rule, standard, or permit when performing a licensed activity.

5. A license may not be revoked or suspended except after a hearing before the director of the department, or the director's designated representative. If a license is suspended or revoked, a new application for licensure may be considered by the department only after the conditions causing the suspension or revocation have been corrected, and evidence of this fact is submitted to the satisfaction of the department.
