Notwithstanding the provisions of Section 34090, the city officer having custody of public records, documents, instruments, books, and papers, may, without the approval of the legislative body or the written consent of the city attorney, cause to be destroyed any or all of the records, documents, instruments, books, and papers, if all of the following conditions are complied with:

1. (a) The record, paper, or document is photographed, microphotographed, reproduced by electronically recorded video images on magnetic surfaces, recorded in the electronic data processing system, recorded on optical disk, reproduced on film or any other medium that is a trusted system and that does not permit additions, deletions, or changes to the original document, or reproduced on film, optical disk, or any other medium in compliance with Section 12168.7 for recording of permanent records or nonpermanent records.
2. (b) The device used to reproduce the record, paper, or document on film, optical disk, or any other medium is one which accurately and legibly reproduces the original thereof in all details and that does not permit additions, deletions, or changes to the original document images.
3. (c) The photographs, microphotographs, or other reproductions on film, optical disk, or any other medium are made as accessible for public reference as the original records were.

4. (d) A true copy of archival quality of the film, optical disk, or any other medium reproductions shall be kept in a safe and separate place for security purposes.

   However, no page of any record, paper, or document shall be destroyed if any page cannot be reproduced on film with full legibility. Every unreproducible page shall be permanently preserved in a manner that will afford easy reference.

   For the purposes of this section, every reproduction shall be deemed to be an original record and a transcript, exemplification, or certified copy of any reproduction shall be deemed to be a transcript, exemplification, or certified copy, as the case may be, of the original.
