Rule development
2024 rulemaking
The Board of Boiler Rules and the Washington Department of Labor & Industries (L&I) are considering an increase in program fees and clarifying the definition for pool heaters.
An increase in fees by the fiscal growth factor of 6.41% is needed to cover operating expenses.
The updates would also amend the definition of “pool heaters” to clarify inspection requirements.
If adopted, the rule amendments would take effect July 1, 2025.
