PROPOSED RULES

BUILDING CODE COUNCIL


[ Filed August 2, 2000, 10:36 a.m. ]

Original Notice.

Preproposal statement of inquiry was filed as WSR 00-03-017.

Title of Rule: Amendment of chapters 51-44 and 51-45 WAC (amendment of the 1997 Edition of the Uniform Fire Code and Fire Code Standards).

Purpose: To consider whether to amend the 1997 Editions of the Uniform Fire Code and Fire Code Standards, Published by the International Fire Code Institute.

Statutory Authority for Adoption: RCW 19.27.031 and 19.27.074.

Statute Being Implemented: Chapters 19.27 and 34.05 RCW.

Summary: The proposed rules include adoption of amendments to the 1997 Uniform Fire Code and Fire Code Standards, including editorial corrections, elimination of conflicting language and improved requirements for fleet fueling and ammonia refrigeration.

Reasons Supporting Proposal: RCW 19.27.031 and 19.27.074.

Name of Agency Personnel Responsible for Drafting and Implementation: Al Rhoades, P.O. Box 48300, Olympia, WA 98504-8300, (360) 586-8999; and Enforcement: Local jurisdictions.

Name of Proponent: Washington State Building Code Council, governmental.

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.

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

Explanation of Rule, its Purpose, and Anticipated Effects: The proposed rule will amend chapters 51-44 and 51-45 WAC. Chapters 51-44 and 51-45 WAC adopt and amend the 1997 Edition of the Uniform Fire Code (UFC) and the Uniform Fire Code Standards published by the International Fire Code Institute. The purpose is to further amend the 1997 UFC to make editorial corrections and other improvements in the code language. The proposed amendments will provide greater safety and flexibility than the published version for application in Washington state.

Regulatory Review: In compliance with Executive Order 97-02, regulatory improvement, the following criteria for regulatory review will be considered at the time of final adoption of the rule.

1. Need. This rule is necessary to comply with the requirements of RCW 19.27.074. The council must regularly review the Uniform Fire Code and Uniform Fire Code Standards, and adopt amendments as deemed appropriate by the council. The purpose and objective of this review, as given in RCW 19.27.020, is to promote the health, safety and welfare of the occupants or users of buildings; to require minimum construction standards for the state of Washington; to permit the use of modern technical methods; to eliminate restrictive, obsolete, conflicting, duplicating and unnecessary regulations; and to provide standards to make buildings accessible to and usable by physically disabled persons. The technical advisory groups appointed by the council have identified rules that are obsolete, duplicative or ambiguous, and have proposed amendments and revisions.

2. Effectiveness and Efficiency. The mission of the council is to adopt building codes for uniform application throughout the state. In the course of the regular rule review, the council examined regulatory alternatives and new technologies. The council has identified where alternatives can be used effectively and efficiently. The council efficiently achieves uniform state building codes by serving as the central administrative agency for state-wide adoption of building codes.

3. Clarity. To enhance clarity, only those subsections with a state amendment will be filed under the main section number. The balance of the main section will remain as written in the national uniform code, as adopted by reference, unless otherwise noted.

4. Intent and Statutory Authority. The proposed rule is consistent with the legislative intent of the statute, chapter 19.27 RCW. The statute gives the council sufficient authority to maintain the State Building Code, and to amend the Uniform Fire Code and Uniform Fire Code Standards.

5. Coordination. The council rule-making process includes participation by national, state, and local building, fire, mechanical and plumbing officials, as well as state agency representatives for the Departments of Social and Health Services, Health, Labor and Industries, and the State Fire Marshal. The council actively seeks participation from other state agencies to assure that duplication and inconsistency is eliminated.

6. Cost. The council appointed technical advisory groups and an Economic and Regulatory Assessment Committee to examine the costs and benefits associated with the revisions to the building codes.

7. Fairness. The state amendments to the Uniform Fire Code proposed by the council are intended to mitigate disproportionate impact on the regulated community. The council is made up of representatives from the regulated community, as well as public and regulatory officials. In addition, the council enlisted the assistance of technical advisory groups, made up of individuals, organizations and businesses impacted by the building codes, to review changes and proposals.

Proposal Changes the Following Existing Rules: The proposed amendments will improve the existing rules by correcting editorial errors and updating code language to allow improved practices to be utilized. The amendments added to the 1997 UFC are as follows:

1. Section 103.2.1.1: Editorial change to remove unnecessary duplicative language.

2. Section 105.8: Adds permit requirement to fuel motor vehicles directly from a tank vehicle, or to operate a site where motor vehicles are fueled directly from tank vehicles.

3. Section 207 F: Adds definition for Family Child Day Care Home.

4. Section 216 - O: Editorial changes to coordinate definitions with other proposed changes.

5. Section 219 - R: Editorial changes to coordinate definitions with other proposed changes.

6. Section 1007.2.12.10: Deletion of section to remove conflicting language regarding visual alarms.

7. Section 1007.3.3.3.4: Editorial changes to clarify intent regarding visual alarms.

A small business economic impact statement has been prepared under chapter 19.85 RCW.

Small Business Economic Impact Statement
The State Building Code Council is proposing to adopt amendments to chapter 51-44 WAC, the 1997 Uniform Fire Code published by the International Fire Code Institute. The council appoints Technical Advisory Groups (TAGs) to conduct a comprehensive review of proposed code amendments. The participants on the Fire Code TAG represent architects, mechanical engineers, fire officials, insurance companies, model code organizations, homebuilders, large commercial organizations, utilities, and state agencies. The Economic and Regulatory Assessment Committee consists of council members as specified in SBCC by-laws.

Proposed amendments to WAC 51-44-6309, Pressure-relief Discharge of Ammonia Refrigerant, and to WAC 51-44-6307.1 Location of Emergency Control Box, have been identified by the Fire Code TAG and the Economic and Regulatory Assessment Committee as having a cost impact on businesses required to comply with the rule.

The proposed amendment to 6309 clarifies where the local fire chief has authority to require a containment system for ammonia discharge or to require engineering analysis to show atmospheric discharge is safe. The current rule implies the jurisdiction's authority to require a containment system by reference to industry standards. The amendment gives express authority to the fire chief to determine where an atmospheric release of ammonia refrigerant may reasonably be expected to result in significant concentrations of ammonia which may be hazardous to persons or other premises.

Cold storage industries would be impacted, where required by the local fire chief to install a containment system or complete an engineering analysis. For an ammonia refrigeration system with an overall cost of $500,000 to $750,000, the containment system would cost about $8,000 to $10,000. According to criteria established by Economic Committee, this represents more than a minor cost impact. The containment system represents between 1% and 2% of the total system cost.

The cost of the emergency control box is estimated at between $3,000 and $4,000, again assuming an overall system cost $500,000 to $750,000. This represents between 1/2 and 3/4 of 1% of total cost. The Economic Committee criteria designates 1/4 of 1% of total cost or less as "minor cost."

The cost of containment systems and an emergency control box are proportional to system capacity. Assuming that equivalent system capacities are capable of storing equivalent volume of product, the code amendments would not pose a disproportionate impact on small business. Further, the local fire chief must make a determination based on the industry standards, already in effect. The intent of the current code is to require an emergency control box. Atmospheric release installed according to the standards (ASHRAE 15-1994, IIAR 2-1992) is the general rule. The added costs for containment systems would apply only where a safety hazard exists.

A copy of the statement may be obtained by writing to Tim Nogler, Managing Director, Washington State Building Code Council, P.O. Box 48300, Olympia, WA 98504-8300, phone (360) 586-0486, fax (360) 586-5880.

RCW 34.05.328 does not apply to this rule adoption. The State Building Code Council is not listed in this section as one of the agencies required to comply with this regulation.

Hearing Location: Spokane City Council Chambers, West 808 Spokane Falls Boulevard, Spokane, WA on September 15, 2000, at 10:00 a.m.; and at the Radisson Hotel, 17101 International Boulevard, SeaTac, WA, on October 13, 2000, at 10:00 a.m.
