Each such contingency plan shall also include a provision by which the jurisdiction shall extend the closing time for the polling place in the case where there is a delay in the timely opening or operation of a polling place or when voters have waited more than 30 minutes to cast a ballot. Such extended poll hours shall be commensurate with the total time of the delayed opening or operation of the polling place and for the total period of time exceeding 30 minutes that voters had to wait in order to cast a ballot at the polling place from the time of arrival.
