Any person affected by a notice issued in connection with the enforcement of this chapter, or of any rule and regulation adopted pursuant thereto, may request and shall be granted a hearing before the Board of Health, provided the person files in the office of the Secretary of the Board of Health a written petition requesting the hearing and setting forth a brief statement of the grounds within 10 days after the day the notice was served. Upon receipt of the petition, the Board of Health shall set a time and place for the hearing and shall give the petitioner written notice thereof. At the hearing the petitioner shall be given an opportunity to be heard and to show why such notice should be modified or withdrawn. The hearing shall be commenced not later than 10 days after the day on which the petition was filed, provided that upon application of the petitioner the Board of Health may postpone the date of the hearing for a reasonable time beyond the ten-day period if, in its judgment, the petitioner has submitted a good and sufficient reason for such postponement. After the hearing the Board of Health shall sustain, modify or withdraw the notice, depending upon its findings as to whether the provisions of this chapter and the rules and regulations adopted pursuant thereto have been complied with. If the Board of Health sustains or modifies the notice it shall be deemed to be an order. Any notice served pursuant to this chapter shall automatically become an order if a written petition for a hearing is not filed in the office of the Board of Health within 10 days after the notice is served. The proceedings at the hearing, including the findings and decision of the Board of Health, shall be summarized, reduced to writing and entered as a matter of public record in the office of the Board of Health. The record shall also include a copy of every notice or order issued in connection with the matter. Any person aggrieved by the decision of the Board of Health may seek relief in any court of competent jurisdiction as provided by the laws of the state. Whenever the Board of Health finds that an emergency exists which requires immediate action to protect the public health or safety it may, without notice or hearing, issue an order reciting the existence of an emergency and requiring that such action be taken as it deems necessary to meet the emergency. Notwithstanding the other provisions of this chapter, the order shall be effective immediately. Any person to whom the order is directed shall comply therewith immediately but upon petition to the Board of Health shall be afforded a hearing as soon as possible. After the hearing, depending upon its findings as to whether the provisions of this chapter and the rules and regulations adopted pursuant to thereto have been complied with, the Board of Health shall continue the order in effect, modify or revoke it.
