County officers in counties, as defined in this act, may dispose of all county records in their custody, provided they follow the schedules and procedures prescribed by the county records committee and maintain a log of individual disposition actions involving nonpermanent records. Copies of such logs, in a form approved by the committee, shall be submitted annually to the commission. Original records scheduled for permanent retention may be disposed of if the county officer creates and maintains a copy of the original in conformance with section 4.1 and receives written permission from the commission. Written permission from the commission is required only for disposition actions involving records scheduled for permanent retention, records not listed on the schedules and records selected for transfer to the State Archives.
