These rules and regulations are adopted pursuant to and in accordance with chapter 34.05 RCW. The purpose is to provide standards and procedures necessary to ensure the implementation of a comprehensive offender work program. (See RCW 72.09.015(32).) The headings and captions for the above classes are used for convenience only and do not constitute a part hereof. The use of the term "class" to identify a work program does not restrict the department to a singular description of an offender work program within that class or the use of other offender work programs authorized by separate statute. The secretary may adopt policies providing further guidance for establishing, among other things, offender participation eligibility and security requirements for each class of work program.
