April 5, 2021 -- EPA is committed to ensuring that new wood stoves and other wood burning devices comply with Clean Air Act standards to reduce health-harming pollution. In light of information from states and other stakeholders provided in late 2020 and early 2021, the agency is taking a number of actions to address concerns about the methods and manner in which new wood stoves are being tested for compliance with the 2015 New Source Performance Standards under the Clean Air Act.
These actions will take time and continued engagement with stakeholders. Given the concerns raised, EPA is carefully reviewing both current and new Certifications of Compliance and will take actions as appropriate.
