Purpose of the Proposal and Its Anticipated Effects, Including Any Changes in Existing Rules: The state Building Code Council has adopted an emergency rule modification to this section when it was determined that language adopted previously would cause undue expense for residential systems. The proposed permanent rule would establish an economizer threshold of 54,000 Btu/h for residential cooling units.
Reasons Supporting Proposal: RCW 19.27A.025 and 19.27A.045.
Statutory Authority for Adoption: RCW 19.27A.025, 19.27A.045.
Statute Being Implemented: Chapters 19.27, 19.27A, 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: Washington 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 jurisdictions.
No small business economic impact statement has been prepared under chapter 19.85 RCW. This proposed amendment is intended to reduce the cost of residential cooling systems and was determined to not have a disproportionate cost on small businesses. This rule effectively cancels out the code change previously proposed and reinstates the previous code provision; therefore, there is no difference in cost.
A cost-benefit analysis is not required under RCW 34.05.328. This rule reinstates a previous rule and poses no change in cost or compliance.
