[Statutory Authority: RCW 40.14.020(6). WSR 00-20-038, § 434-663-530, filed 9/28/00, effective 10/29/00. Statutory Authority: Chapter 40.14 RCW. WSR 94-04-102, § 434-663-530, filed 2/1/94, effective 3/7/94.]



PDF434-663-600

Retention scheduling and disposition of public records.

Conversion to an imaging system does not automatically authorize the destruction of the source documents for which images have been created. Destruction of, or changes to the retention period of, any public records due to conversion to or the use of a new media requires legal approval of the state or local records committee of the state of Washington under chapter 40.14 RCW, chapter 434-635 WAC, and other applicable state laws.
[Statutory Authority: RCW 40.14.020(6). WSR 00-20-038, § 434-663-600, filed 9/28/00, effective 10/29/00. Statutory Authority: Chapter 40.14 RCW. WSR 94-04-102, § 434-663-600, filed 2/1/94, effective 3/7/94.]



PDF434-663-615

Records retention scheduling for records on imaging system.

The required retention scheduling of public records to be created, maintained, accessed, distributed, or preserved by government entities on electronic imaging systems should be done prior to the creation or copying of images of those records. Retention schedules shall be based on the information content and function of the record series. Record series documenting electronic information system operation, and maintenance must also be included on the records retention schedule approved for the agency using the system. Electronic image media rendered obsolete through the verified accurate migration of its images to a more current media for readability may be considered a redundant version and disposed of as directed by chapter 40.14 RCW.
[Statutory Authority: RCW 40.14.020(6). WSR 00-20-038, § 434-663-615, filed 9/28/00, effective 10/29/00.]

PDF434-663-640

Disposition of records identified by records committee as archival.

Public records that are designated "archival" or "potentially archival" by the state or local records committee may not be destroyed without committee approval, even where images of those records have been produced and stored on an electronic imaging system.
[Statutory Authority: RCW 40.14.020(6). WSR 00-20-038, § 434-663-640, filed 9/28/00, effective 10/29/00.]



PDF434-663-700

Usability of image and index data over time.

Maintaining access to and usability of electronic records requires the ability to process images and indexes both on the computer system on which they were created and on their replacement computer systems without loss of information for the full retention period approved for that record. Ensuring the readability of electronic records over time requires the maintenance of proper environmental conditions, periodic recopying, and strategies to preserve data by migration from one generation of technology to another through a commitment to open architecture.
[Statutory Authority: RCW 40.14.020(6). WSR 00-20-038, amended and recodified as § 434-663-700, filed 9/28/00, effective 10/29/00. Statutory Authority: Chapter 40.14 RCW. WSR 94-04-102, § 434-663-400, filed 2/1/94, effective 3/7/94.]



PDF434-663-705

Recordkeeping capabilities.

(2) Ability to properly eliminate or dispose of records that exceed their retention periods as established under RCW 40.14.050 through 40.14.070.
(3) Record authentication functions as needed to meet legal, audit, and administrative requirements including automatic, computer-generated maintenance of the date and time of record creation or updating, the identity of the user or system that created or updated the record, and a system-enforced log of disposition actions.
(4) Protection against unauthorized access to records by means of a password hierarchy or other system security.
(5) Indexing capabilities that provide flexibility in associating a record series with multiple subject categories, that facilitate access and retrieval, and that provide links to related records or supporting documentation.
[Statutory Authority: RCW 40.14.020(6). WSR 00-20-038, § 434-663-705, filed 9/28/00, effective 10/29/00.]



PDF434-663-710

Defining indexing requirements.

The selection of indexing methods and terms should be based on an analysis of the retrieval requirements associated with a particular application, and must ensure efficient and accurate retrieval of images and information. The design and content of the index should utilize standard attributes wherever available and take into account the security of the index and the retrieval requirements of both current and future users of the records including agency personnel, researchers, and the public.
[Statutory Authority: RCW 40.14.020(6). WSR 00-20-038, amended and recodified as § 434-663-710, filed 9/28/00, effective 10/29/00. Statutory Authority: Chapter 40.14 RCW. WSR 94-04-102, § 434-663-410, filed 2/1/94, effective 3/7/94.]



PDF434-663-720

Preservation strategy.

For an electronic image system containing public records with a retention period of ten years or longer or records containing archival information, one or more of the following preservation strategies must be employed:
(1) Retain the original paper documents;
(2) Microfilm the original documents;
(3) Migrate optical media and magnetic media at least every ten years or sooner as is necessary to avoid technical obsolescence, loss of readability, and excessive read error rates; or
(4) Record the electronic images on industry standard microfilm at the same density at which they were scanned.
[Statutory Authority: RCW 40.14.020(6). WSR 00-20-038, amended and recodified as § 434-663-720, filed 9/28/00, effective 10/29/00. Statutory Authority: Chapter 40.14 RCW. WSR 94-04-102, § 434-663-420, filed 2/1/94, effective 3/7/94.]



PDF434-663-730

Header information on image files.

An electronic imaging system containing public records with a retention period of ten years or longer or records containing archival information must use a nonproprietary file header format such as Tagged Image File Format (TIFF) or a header that complies with ANSI-AIIM MS53, File Format for Storage and Exchange of Images, or Bi-level File Format: Part 1.
[Statutory Authority: RCW 40.14.020(6). WSR 00-20-038, § 434-663-730, filed 9/28/00, effective 10/29/00.]



PDF434-663-740

Security backup copies.

Security backup copies must be made of electronic imaging system records stored on electronic media. The methods and frequency of backup should be determined by the amount of information that would be lost if data had to be restored using the previous backup. Since backup copies are also subject to media failure, it is recommended that redundant (multiple) backup copies be made and stored at different locations, with one copy stored offsite. In order to ensure accessibility of data, at least one redundant backup copy should be recorded in a nonproprietary format. Security backup copy media must be inspected for quality using de facto or industry standards on a regular schedule and replaced before predicted failure. If the primary backup copy of an operational imaging system is found to deviate from the primary production copy due to suspected corruption or read errors, the discrepancy must be located and both the production and backup copies must be corrected to contain accurate versions of the original images.
[Statutory Authority: RCW 40.14.020(6). WSR 00-20-038, § 434-663-740, filed 9/28/00, effective 10/29/00.]



PDF434-663-750

Ensuring usability.

At a minimum, the system must include an electronic error checking utility that will check the integrity of the data when written to the media.
[Statutory Authority: RCW 40.14.020(6). WSR 00-20-038, recodified as § 434-663-750, filed 9/28/00, effective 10/29/00. Statutory Authority: Chapter 40.14 RCW. WSR 94-04-102, § 434-663-450, filed 2/1/94, effective 3/7/94.]



PDF434-663-760

PDF434-663-770

Continued access to data.

If access to data in an existing electronic imaging system cannot be maintained for the specified retention period of the records stored in that system, the images must be migrated, without loss to the images or indexes, at the time of acquisition or implementation of a new system. Access to electronic data which has not been migrated to a new system requires preserving the data, the storage medium in which the data is kept, and whatever hardware, operating system, and applications software is needed to view and use the data.

Data conversion costs.

The adoption of new electronic imaging systems may require significant expenditures for conversion of information maintained in existing electronic formats to the formats required by new imaging systems. System planning should include analysis of future information access, maintenance, data conversion, and security costs.
