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

On November 21, 2018, EPA proposed amendments to the New Source Performance Standards (NSPS) for Residential Wood Heaters issued in 2015. The proposed amendments would allow retailers additional time to sell the existing inventory of hydronic heaters and forced-air furnaces. EPA is also taking comment on a similar sell-through provision for wood stoves and on whether the pellet fuel requirements should be revised.

In addition, EPA is issuing an Advance Notice of Proposed Rulemaking (ANPR) to seek comment on several aspects of the 2015 NSPS, including the feasibility of the upcoming May 2020 compliance date for manufacturers of hydronic heaters and forced-air furnaces to meet a second, more stringent emissions limit, known as the Step 2 limit.
