319.333.  Notice of violation, procedure. — Any individual or person using explosives who the state fire marshal or his or her representative determines, upon substantial evidence, to be in violation of sections 319.300 to 319.345 may be issued a notice of violation by the division of fire safety.  Any hearings regarding suspension or revocation of a blaster's license shall be conducted under the provisions of subsection 10 of section 319.306, rather than the provisions of this section.  Any notice of violation of any provision of sections 319.300 to 319.345 shall be in writing and shall state the section or sections violated and the circumstance of the violation, including date, place, person involved, and the act or omission constituting the violation.  The notice shall also inform the person receiving the notice of the right to request a hearing before the state blasting safety board for any violation, except for the violation of failure to hold a blasting license as required by section 319.306 for which no appeal may be made.  The recipient may request a hearing within forty-five days of the date the notice was received.  If a hearing is requested, the state fire marshal shall immediately inform the chairman of the board.  The person receiving the notice, the state fire marshal, and the chairman of the board shall establish a mutually acceptable date and place for the hearing, which in no case shall be more than thirty days after the hearing was requested.  The hearing shall be conducted as an uncontested case, although the person or the state fire marshal may be represented by an attorney.  Within fifteen days of such hearing, the board shall notify the person of its decision on the appeal, which may include upholding, modifying, or disapproving the notice of violation.  The board's action upon the appeal shall be decided by majority vote.  If the notice of violation is upheld by the board, in whole or part, upon a separate majority vote of the board, the person may be referred for enforcement action as provided in section 319.327.
