Concerning wood burning devices.

Washington's SB 5174 updates state regulations for wood-burning devices to align with stricter federal air quality standards, directly affecting homeowners, manufacturers, and retailers selling new woodstoves. The bill requires the Department of Ecology to adopt emission standards matching federal rules (effective 2025), creates a voluntary state verification program to ensure devices meet clean air requirements, and allows verified stoves to qualify for state grant programs. It addresses gaps identified in EPA certification failures by strengthening oversight and consumer protections. The law applies to new woodstoves, fireplaces, and related devices sold for residential use, aiming to reduce harmful emissions.
