Original Notice.

     Preproposal statement of inquiry was filed as WSR 05-17-104.

     Title of Rule and Other Identifying Information: Chapter 296-24 WAC, Part J-3, Powered platforms; chapter 296-155 WAC, Part J-1, Elevating work platforms; and chapter 296-869 WAC, Elevating work platforms.

     Hearing Location(s): Department of Labor and Industries, Auditorium, 7273 Linderson Way S.W., Tumwater, WA, on May 31, 2006, at 9:00 a.m.

     Date of Intended Adoption: July 7, 2006.

     Submit Written Comments to: Jim Hughes, Project Manager, P.O. Box 44620, Olympia, WA 98507-4620, e-mail hugw235@lni.wa.gov, fax (360) 902-5619, by noon, June 9, 2006.

     Assistance for Persons with Disabilities: Contact Kimberly Johnson by May 24, 2006, at (360) 902-5008, TTY (360) 902-4645, or e-mail rhok235@lni.wa.gov.

     Purpose of the Proposal and Its Anticipated Effects, Including Any Changes in Existing Rules: Portions of chapter 296-24 WAC, Part J-3, Powered platforms and chapter 296-155 WAC, Part J-1, Elevating work platforms, have been rewritten for clarity and usability, while making housekeeping revision. Existing rules will be combined into a single book titled elevating work platforms, chapter 296-869 WAC.

     Reasons Supporting Proposal: Rewritten rules will be easier to use and understand for both employers and employees.

     Statutory Authority for Adoption: RCW 49.17.010, 49.17.040, 49.17.050, and 49.17.060.

     Statute Being Implemented: Chapter 49.17 RCW.

     Rule is not necessitated by federal law, federal or state court decision.

     Name of Proponent: Department of labor and industries, governmental.

     Name of Agency Personnel Responsible for Drafting: Tracy Spencer, Tumwater, Washington, (360) 902-5530; Implementation and Enforcement: Stephen M. Cant, Tumwater, Washington, (360) 902-5495.

     No small business economic impact statement has been prepared under chapter 19.85 RCW. RCW 19.85.030 (1)(a) requires a small business economic impact statement (SBEIS) only when a rule will "impose more than a minor cost on businesses in an industry." An analysis of the proposed rule reveals that in addition to not imposing new costs on businesses, these revisions will make WISHA rules easier for employers and employees to understand and use, and thus save time and resources. Therefore, no SBEIS is required.

     A cost-benefit analysis is not required under RCW 34.05.328. There are no costs to assess within these proposed rules.
