Mississippi Code
In General
§ 49-17-29. Permit Board; prohibitions; air and water permits; solid waste and hazardous permits; permit hearings; permit appeals

The Permit Board shall fix the time and place of the formal hearing and shall notify the permittee of that time and place.
In conducting the formal hearing, the Permit Board shall have the same full powers as to subpoenaing witnesses, administering oaths, examining witnesses under oath and conducting the hearing, as is now vested by law in the Mississippi Public Service Commission, as to the hearings before it, with the additional power that the Executive Director of the Permit Board may issue all subpoenas at the instance of the Permit Board or at the instance of any interested party. Any subpoenas shall be served by any lawful officer in any county to whom the subpoena is directed and return made thereon as provided by law, with the cost of service being paid by the party on whose behalf the subpoena was issued. Witnesses summoned to appear at the hearing shall be entitled to the same per diem and mileage as witnesses attending the circuit court and shall be paid by the person on whose behalf the witness was called. Sufficient sureties for the cost of service of the subpoena and witness fees shall be filed with the Executive Director of the Permit Board at the time that issuance of the subpoena is requested. At a hearing, any interested party may present witnesses and submit evidence and cross-examine witnesses.
The Permit Board may designate a hearing officer to conduct the formal hearing on all or any part of the issues on behalf of the Permit Board. The hearing officer shall prepare the record of the formal hearing conducted by that officer for the Permit Board and shall submit the record to the Permit Board.
Upon conclusion of the formal hearing, the Permit Board shall enter in its minutes the board's decision affirming, modifying or reversing its prior decision to issue, reissue, deny, modify or revoke a permit. The Permit Board shall prepare and record in its minutes findings of fact and conclusions of law supporting its decision. That decision, as recorded in its minutes with its findings of fact and conclusions of law, shall be final unless an appeal, as provided in this section, is taken to chancery court within twenty (20) days following the date the decision is entered in the board's minutes.
