Final Amendments to the New Source Performance Standards for Residential Wood Heaters

April 2, 2020, EPA published the finalized amendments to the 2015 New Source Performance Standards (NSPS) for New Residential Wood Heaters, New Hydronic Heaters and Forced-Air Furnaces (collectively referred to as “wood heating devices”).  

These final amendments contain several actions:  

  • EPA is maintaining compliance dates that were established in the original NSPS, which means retailers will have until May 15, 2020, to sell wood heating devices that do not comply with more stringent emission standards. 
  • EPA is removing the pellet fuel minimum requirements from the 2015 NSPS. However, the agency is retaining the prohibition – stated in the eighth pellet fuel minimum requirement – that pellet fuel must not contain any of the prohibited fuels listed in the 2015 NSPS. Minimum requirements are already included in the standards used by the Pellet Fuels Institute and other EPA-approved third-parties for the grading of pellet fuels. 
  • EPA is clarifying requirement regarding the use of unseasoned wood in pellet fuel production. 

This final action helps ensure that, in the future, customers buying wood heaters anywhere in the United States will be able to choose from cleaner-burning models. Today’s actions do not apply to wood heaters that are currently in use in people’s homes, or to fireplaces, backyard barbecues, chimineas, or fire pits.
