PROPOSED RULES

BUILDING CODE COUNCIL


[ Filed July 20, 2007, 3:49 p.m. ]

Original Notice.

Preproposal statement of inquiry was filed as WSR 07-09-097.

Title of Rule and Other Identifying Information: Amendment of chapter 51-50 WAC further amendment of the 2006 Edition of the International Building Code (IBC).

Hearing Location(s): Spokane City Council Chambers, West 808 Spokane Falls Boulevard, Spokane, WA, on September 14, 2007, at 10:00 a.m.; and at the Tukwila Community Center, 12424 42nd Avenue South, Tukwila, WA, on October 12, 2007, at 10:00 a.m.

Date of Intended Adoption: November 9, 2007.

Submit Written Comments to: John Neff, Council Chair, P.O. Box 42525, Olympia, WA 98504-2525, e-mail sbcc@cted.wa.gov, fax (360) 586-9383, by October 12, 2006 [2007].

Assistance for Persons with Disabilities: Contact Sue Mathers by August 31, 2007, TTY (360) 586-0772 or (360) 725-2966.

Purpose of the Proposal and Its Anticipated Effects, Including Any Changes in Existing Rules: This proposal to amend the 2006 International Building Code would make the following changes:

Section 0200: The definition of "nightclub" is revised in accordance with the definition adopted by chapter 434, Laws of 2007 (2SHB 1811).

Section 0308: The description of a Group I-1 occupancy is revised to institutional structures housing over six persons on a twenty-four-hour basis, rather than over sixteen persons, to coordinate with other state regulations.

Section 0310: The Group R-2 description is revised to include congregate care language unintentionally left out of the previous document. The Group R-3 description also adds back in the language regarding congregate care.

Section 0406: A new section 406.5.3 is proposed to require an emergency back-up power source in motor fuel dispensing stations.

Sections 0702, 0704, and 0705: These sections dealing with the requirement that fire walls be constructed to remain standing when the construction on either side collapses is in conflict with the requirements of Chapter 16 requirements for seismic design. Thus, it is proposed to change the definition of "Firewall" and not adopt the two sections titled "Structural stability."

Section 0903: The requirement for automatic fire sprinklers in existing nightclub facilities is revised to coordinate with the new effective date established by chapter 434, Laws of 2007 (2SHB 1811).

Section 1403: Section 1403.2, Weather protection, is amended to clarify that an airspace is not required behind wood or fiber cement siding.

Section 1607: Table 1607.1 is amended to add a new category for live load, "Other assembly areas."

Section 1613: Is added to correct errors found in equations in the ASCE 7 manual.

Section 2702: A new section 2702.2.21 is proposed to require an emergency power source in all Group I-1 and I-2 occupancies.

Section 2900: Table 2902.1 is amended to require lavatories in all patient care areas as defined in new footnote 10.

Section 3001: Section 3002.1 is amended to add a requirement for an elevator sized to accommodate an ambulance stretcher in all Group R-1, R-2, and I occupancy buildings required to provide elevators.

Reasons Supporting Proposal: RCW 19.27.031 and 19.27.074.

Statutory Authority for Adoption: RCW 19.27.031 and 19.27.074.

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 issues proposed in the rules shown below.

Name of Proponent: Washington state building code council, governmental.

Name of Agency Personnel Responsible for Drafting and Implementation: Tim Nogler, P.O. Box 42525, Olympia, WA 98504-2525, (360) 725-2969; and Enforcement: Local jurisdictions.

No small business economic impact statement has been prepared under chapter 19.85 RCW. No disproportionate impact on small business was identified. This rule will modify the adoption of model codes to stay current with national standards for the benefit of industry and Washington state interests. New state amendments clarify and simplify the code.

A cost-benefit analysis is not required under RCW 34.05.328. The state building code council is not listed in this section as one of the agencies required to comply with this statute.
