BUILDING CODE COUNCIL


[ Filed August 4, 2005, 8:16 a.m. ]

Original Notice.

Preproposal statement of inquiry was filed as WSR 5-16-145 [05-13-145.]

Title of Rule and Other Identifying Information: Chapter 51-50 WAC, Adoption and amendment of the 2003 International Building Code, Sections 202, 903, 909, 1008, and 1101.

Hearing Location(s): Renton Holiday Inn Select, One South Grady Way, Renton, WA 98055-2500, on October 14, 2005, at 10:00 a.m.

Date of Intended Adoption: November 4, 2005.

Submit Written Comments to: John Neff, P.O. Box 42525, Olympia, WA 98504-2525, e-mail sbcc@cted.wa.gov, fax (360) 586-9383, by October 13, 2005.

Assistance for Persons with Disabilities: Contact Sue Mathers by September 30, 2005, TTY (360) 753-7427 or (360) 725-2966.

Purpose of the Proposal and Its Anticipated Effects, Including Any Changes in Existing Rules: Chapter 148, Laws of 2005, requires the state Building Code Council (council) to adopt rules requiring automatic sprinkler systems in all buildings containing a nightclub as defined in the bill. This proposed language adds the requirements from ESHB 1401 to the building code.

In addition, the council has adopted an emergency rule which requires that wired glass installed in hazardous locations meet the same safety requirements as other types of glass. This proposal would adopt that requirement as a permanent rule.

This proposed rule also includes the following changes to published language in the IBC: Clarification of inspection requirements for elevator shaft pressurization; provide an exception to allow manually operated sliding doors in spaces with an occupant load less than ten; and deletion of the requirement for elevator button labeling to conform with the ICC/ANSI A117.1.

Reasons Supporting Proposal: RCW 19.27.031 and 19.27.074.

Statutory Authority for Adoption: RCW 19.27.074 and 19.27.031.

Statute Being Implemented: Chapters 19.27 and 34.05 RCW.

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

Agency Comments or Recommendations, if any, as to Statutory Language, Implementation, Enforcement, and Fiscal Matters: The council is seeking comments on the issue proposed in the rule shown below.

Name of Proponent: State Building Code Council, governmental.

Name of Agency Personnel Responsible for Drafting and Implementation: Krista Braaksma, P.O. Box 42525, Olympia, WA 98504-2525, (360) 725-2964; and Enforcement: Local jurisdiction.

No small business economic impact statement has been prepared under chapter 19.85 RCW. The sprinkler provision of this rule, in Section 903.2, would have an impact on small business; however, the effects are mitigated by a special property tax exemption provided through chapter 148, Laws of 2005, which would extend for ten years after the initial application by property owners.

The remaining provisions would not have a cost impact on small businesses. The council has reviewed material stating that wired glass that meets the safety provisions of Section 2406 is available at the same cost. The remaining provisions provide clarification or cost savings.

A cost-benefit analysis is not required under RCW 34.05.328. The council is not one of the agencies required to comply with this statute.
