EMERGENCY RULES
[Filed June 21, 2016, 11:18 a.m., effective July 1, 2016]
Effective Date of Rule: July 1, 2016.
Purpose: This emergency rule is necessary to provide consistency between new requirements for minimum live load values for exterior balconies and decks, and new tables that detail specific requirements for deck ledger attachment, deck joist spans, deck beam spans and other related requirements. The current rule is not consistent with the requirements of the new tables: The proposed language will remove a sixty lbs/sq. ft. requirement and replace it with forty lbs/sq. ft. in Table R301.5. This modification will create safer conditions for deck construction.
Citation of Existing Rules Affected by this Order: Amending WAC 51-51-0301.
Statutory Authority for Adoption: Chapter
19.27 RCW.
Under RCW
34.05.350 the agency for good cause finds that immediate adoption, amendment, or repeal of a rule is necessary for the preservation of the public health, safety, or general welfare, and that observing the time requirements of notice and opportunity to comment upon adoption of a permanent rule would be contrary to the public interest.
Reasons for this Finding: The current code language creates a potential safety hazard. The lack of detail to support live load requirements for decks and balconies presents an emergency situation that could lead to deck failure; this would constitute a life/safety hazard. Adoption of the emergency rule would correct the values in the table, and would eliminate the potential life/safety hazard.
