Each record must contain at least the following information: (a) The operating area where the interruption occurred; (b) The name of the substation involved; (c) The name of the distribution circuit or distribution sub-circuit involved; (d) The date and time the interruption occurred (if the exact time is unknown, the beginning of an interruption is recorded as the earlier of an automatic alarm or the reported initiation time); (e) The date and time service was restored; (f) The number of customers affected by the interruption; (g) The cause of the interruption; (h) The protective device that made the interruption; and (i) The element involved (e.g., transmission, distribution substation, overhead primary main, underground primary main, transformer, etc.).

(4) For momentary interruptions and momentary interruption events, the company must collect as much information as is reasonable, given the equipment and systems available to identify and record such events. (5) An electric company must retain for at least seven full calendar years the records associated with sections (1) through (2) of this rule. (6) This rule is effective beginning January 1, 2012.
