The department shall cause investigations to be made upon the request of the commission or upon receipt of information concerning alleged violations of sections 260.350 to 260.430 or any standard, rule or regulation, order or license or permit term or condition adopted or issued hereunder, and may cause to be made any other investigations it deems advisable to further the purposes of sections 260.350 to 260.430. Violations shall include obtaining a permit hereunder by misrepresentation or failure to fully disclose all relevant facts.  2. If, in the opinion of the department, the investigation discloses that a violation does exist, it may, by conference, conciliation or persuasion, endeavor to eliminate the violation.  3. In case of the failure by conference, conciliation or persuasion to correct or remedy any claimed violation, or as required to immediately and effectively halt or eliminate any imminent or substantial threats to the health of humans or other living organisms resulting from the claimed violation, the department may order abatement of the violation or may revoke any license, or any hazardous waste transportation vehicle approval or permit which may have been issued hereunder. The department shall cause to have issued and served upon the person complained against a written notice of the order or revocation which shall include a copy of the order or revocation, which shall specify the provision of sections 260.350 to 260.430, or the standard, rule or regulation, order or license or permit term or condition adopted or issued hereunder of which the person is alleged to be in violation and a statement of the manner in which the person is alleged to violate sections 260.350 to 260.430, or the standard, rule or regulation, order or license or permit term or condition. Service may be made upon any person within or without the state by registered or certified mail, return receipt requested. Any person against whom the department issues an order or revocation may appeal it by filing a petition with the commission within thirty days. The appeal shall stay the enforcement of the order or revocation until final determination by the commission. The commission shall set appeals for a hearing at a time not less than thirty days after the date of the receipt of the petition. The commission may sustain, reverse or modify the department's order or revocation or may make such other orders as the commission deems appropriate under the circumstances. If any order or revocation issued by the department is not appealed within the time herein provided, the order or revocation becomes final and may be enforced as provided in section 260.425.  4. Licenses and permits issued hereunder may be suspended, revoked or modified if obtained in violation of sections 260.350 to 260.430 or by misrepresentation or failing to fully disclose all relevant facts, or when required to prevent violations of any provision of sections 260.350 to 260.430 or any standard, rule or regulation, order or license or permit term or condition adopted or issued hereunder, or to protect the health of humans and other living organisms, when such action is required by a change in conditions or the existence of a condition which requires either a temporary or permanent change in the licensed or permitted hazardous waste management practices, subject to the right of appeal as set forth in section 260.410*.  5. When the commission schedules a matter for hearing, the petitioner on appeal may appear at the hearing in person or by counsel, and may make oral argument, submit written brief, offer testimony and evidence and cross-examine witnesses.  6. After due consideration of the record, or upon default in appearance of the petitioner at any hearing of which he has been given notice by registered or certified mail the commission shall issue and enter such final order, or make such final determination as it deems appropriate under the circumstances. It shall notify the petitioner or respondent thereof in writing by certified or registered mail. ­­-------- (L. 1977 H.B. 318 § 13)  *Appeal procedure is provided in § 260.415.
