Alaska Stat. § 40.21.080
An official of a political subdivision of the state having legal custody of public records that are considered by the official to be without legal or administrative value or historical interest may compile lists of these records sufficiently detailed to identify them and submit the lists to the governing body of the political subdivision. The governing body may authorize the disposal and the method of disposal of the records in the list that it finds to be without legal or administrative value or historical interest. The governing body may also, upon request of the legal custodian of the records, authorize in advance the periodic disposal of routine records that the governing body considers to have no legal, administrative, or historical value. After receipt of written authorization from the governing body, the legal custodian of the records may dispose of the records. The legal custodian shall file in the office from which the records were drawn a descriptive list of the records disposed of and a record of the disposal itself. Copies of these documents shall be transmitted to the governing body, which shall file and preserve them.
