	 20.19(1) Notification. The notification requirements in subrules 20.19(1) and 20.19(2) are for the timely collection of electric outage information that may be useful to emergency management agencies in providing for the welfare of individual Iowa citizens. Each electric utility shall notify the board when it becomes apparent that an outage may result in a loss of service for more than two hours and the outage meets one of the following criteria:
	  a.   	 For all utilities, loss of service for more than two hours to substantially all of a municipality, including the surrounding area served by the same utility. A utility may use loss of service to 75 percent or more of customers within a municipality, including the surrounding area served by the utility, to meet this criterion;
	  b.   	 For utilities with 50,000 or more customers, loss of service for more than two hours to 20 percent of the customers in a utility’s established zone or loss of service to more than 5,000 customers in a metropolitan area, whichever is less;
	  c.   	 For utilities with more than 4,000 customers and fewer than 50,000 customers, loss of service for more than two hours to 25 percent or more of the utility’s customers;
	  d.   	 A major event as defined in subrule 20.18(4); or
	  e.   	 Any other outage considered significant by the electric utility. This includes loss of service for more than two hours to significant public health and safety facilities known to the utility at the time of the notification, even when the outage does not meet the criteria in paragraphs 20.19(1)“a” through “d.”
	 20.19(2) Information required.
