Any aggrieved person, firm, or corporation or other entity upon application to the director shall be granted a public hearing on the question of whether or not the continuance of any order in whole or in part is unreasonable in the light of the then prevailing conditions of air pollution, the contribution to the air pollution of any particular activity, and the purposes of this chapter. The public hearing shall be conducted as quickly as possible by the director who shall give public notice of it. The director shall have the power to compel attendance, testimony, and the production of documents by the use of subpoena powers. The number of witnesses and the extent of testimony shall be within his or her control. If the director, upon conclusion of the hearing, determines that the order should be terminated, or modified in any way, he or she shall report the findings and recommendations to the governor for any action that he or she deems appropriate.
