335.100. If the permittee files an answer to the show cause order and requests a hearing, a formal public hearing on the record will be conducted pursuant to the R641 Rules before the Board or at the Board's option by an administrative hearing officer. The hearing officer will be a person who meets minimum requirements for a hearing officer under Utah law. At such hearing the Division will have the burden of establishing a prima facie case for suspension or revocation of the permit based upon clear and convincing evidence. The ultimate burden of persuasion that the permit should not be suspended or revoked will rest with the permittee. The Board or Officer will give 30 days written notice of the date, time and place of the hearing to the Director, the permittee and any intervenor. Upon receipt of the notice the Director will publish it, if practicable, in a newspaper of general circulation in the area of the coal mining and reclamation operations, and will post it at the Division office closest to those operations. Upon written request by the permittee, such hearing may at the Board's option be held at or near the mine site within the county in which the permittee's operations are located.
