Mississippi Code Title 41. Public Health § 41-67-33

(1) The department shall adopt and use procedures for conducting reviews requested by any person aggrieved by the disapproval or requirements for an on-site wastewater disposal system as provided by the department in written form under Section 41-67-6. The procedures shall include that the person may request review by submitting a written request of review to the Director of the Office of Environmental Health. The request for review shall identify the matter contested and state the person's name, mailing address and home and daytime phone numbers. Within ten (10) business days of the receipt of the request for review, the department shall issue in writing a ruling and determination to the person and if any corrections are necessary to any form previously issued by the department, then new forms shall be submitted to the person.

(2) Property owners may apply for a variance from the department by submitting a report for a proposed system to the department from a licensed professional engineer that the proposed wastewater treatment system will properly treat and maintain wastewater on the property and proof that the licensed professional engineer has errors and omissions insurance. The department shall grant the variance but still have authority for final approval to inspect that the system is installed as designed. All forms from the department relating to allowed wastewater systems shall include the variance option.

(3) Any person aggrieved by the ruling issued by the Director of the Office of Environmental Health may apply for a hearing. Any hearing shall be conducted by a hearing officer designated by the department. At the hearing, the hearing officer may conduct reasonable questioning of persons who make relevant factual allegations concerning the proposal. The hearing officer shall require that all persons be sworn in before they may offer any testimony at the hearing, and the hearing officer is authorized to administer oaths. Any person so choosing may be represented by counsel at the hearing. A record of the hearing shall be made, which shall consist of a transcript of all testimony received, all documents and other material introduced, the staff report and recommendation, and any other material as the hearing officer considers relevant. He shall make a recommendation within a reasonable period of time after the hearing is closed and after he has had an opportunity to review, study and analyze the evidence presented during the hearing. The completed record shall be certified to the State Health Officer, who shall consider only the record in making his decision, and shall not consider any evidence or material that is not included. All final decisions regarding the disapproval or requirements for an on-site wastewater disposal system shall be made by the State Health Officer. The State Health Officer shall make his written findings and issue his order after reviewing the record, not to exceed thirty (30) days following his receipt of the record.
