If the authority finds that an imminent peril to public health or safety requires the adoption, amendment, or repeal of any rule upon less than twenty days notice, and states in writing its reasons for such finding, it may proceed without prior notice or hearing or upon such abbreviated notice and hearing as it finds practicable to adopt an emergency rule to be effective for a period not longer than one hundred twenty days without renewal.
