Section 460.2501. Scope.

Rule 1. (1) These rules apply to all books of account and other records prepared by or on behalf of the public utility. See rule 82 of these rules for records which come into the possession of the public utility in connection with the acquisition of property, such as a purchase, consolidation, or merger.

(2)  These rules shall not be construed as excusing compliance with any other lawful requirement for the preservation of records for periods longer than those prescribed herein. Whenever a gas utility collects rates authorized by this commission based on increased supplier rates collected under bond under the authority of the federal energy regulatory commission (FERC), such utility shall maintain sufficient gas consumption records to enable the calculation of refunds to individual customers as may be ordered by the Michigan public service commission. This requirement shall continue in effect until final action by the federal energy regulatory commission (FERC) or until the final decree of the court, if appealed thereto, and until such time as the Michigan public service commission has entered its order authorizing appropriate refunds if such be the case.

(3)  Unless otherwise specified in part 2 of these rules, duplicate copies of records may be destroyed at any time if such duplicate copies do not contain significant information not shown on the originals.

(4)  Records other than those listed in part 2 of these rules may be destroyed at the option of the public utility of records that are used in place of those listed will be preserved for the periods prescribed for the records used for substantially similar purposes and if the retention of records pertaining to added services, functions, and plant, the establishment of which cannot be presently foreseen, will conform to the principles embodied herein.
