(a) The source document, if any, for electronically stored local government record data covered by rules adopted under Section 205.003(a) may be destroyed or returned to the person who filed it for record.

(b) The magnetic tape, optical disk, or similar medium containing the local government record data and the hardware and software necessary to provide access to it must be retained by the local government or be available to the local government until the expiration of the retention period for all source documents, subject to the rules adopted under this chapter.

(c) The source document, if any, for electronically stored local government record data not covered by rules adopted under Section 205.003(a) may be destroyed before the expiration of the retention period for the source document in a records retention schedule issued by the commission if the magnetic tape, optical disk, or similar medium and hardware and software necessary to provide access to local government record data on the media are retained for the retention period in the schedule.
