Notwithstanding the foregoing rules, if the board finds that an imminent peril to public health or safety requires adoption, amendment, or repeal of a rule upon less than twenty days notice of hearing, and states in writing its reasons for that finding, it may proceed without prior notice or hearing or upon abbreviated notice and hearing as it finds practicable to adopt an emergency rule. The board shall make an emergency rule known to persons who will be affected by it by publication in accordance with existing rules or policies pertaining to public notices.
