Revision to the Washington State Implementation Plan; Update to the Solid Fuel Burning Devices Regulations
The Environmental Protection Agency (EPA) is proposing to approve a State Implementation Plan (SIP) revision submitted by the Washington State Department of Ecology (Ecology) received on January 30, 2014. The SIP submission contains revisions to Washington's solid fuel burning device rules to control fine particulate matter (PM2.5) from residential wood combustion. The updated regulations reflect Washington State statutory changes made in 2012, setting revised PM2.5 trigger levels for impaired air quality burn bans and setting criteria for prohibiting solid fuel burning devices that are not certified. The submission also contains updates to the regulations to improve the clarity of the language. We are proposing to approve these changes because they meet the requirements of the Clean Air Act and strengthen the Washington SIP.
