Title: Standards of Performance for New Residential Wood Heaters and New Residential Hydronic Heaters and Forced-Air Furnaces Amendments. 

On March 16, 2015, EPA published a final rule that made revisions to the New Source Performance Standards (NSPS) for new residential wood heaters. The 2015 final rule updated the 1988 NSPS to reflect significant advancements in wood heater technologies and design, broadened the range of residential wood-heating appliances covered by the regulation, and improved and streamlined implementation procedures. This 2015 final rule requires manufacturers to redesign wood heaters to be cleaner and lower emitting. In general, the design changes also make the heaters perform better and be more efficient. On November 30, 2018, EPA published a proposed rule that proposes a 2-year sell-through period for hydronic heaters and forced air furnaces. This sell-through period would allow retailers two additional years after the May 2020 compliance date to sell units that were manufactured before the May 2020 compliance date. This 2018 proposed action also solicited comments regarding whether a similar sell-through period should also be provided for woodstoves and solicited comments on whether the pellet fuel requirements in the 2015 NSPS should be removed or revised. In this upcoming final action, EPA will address and respond to comments and finalize amendments regarding the sell-through period for each type of wood burning device, and possibly other amendments regarding pellet fuel requirements, if appropriate.

In this final rule, EPA intends to amend the 2015 New Source Performance Standards (NSPS) for residential wood heaters, hydronic heaters and forced-air furnaces by removing certain minimum requirements for pellet fuel regarding density, size and content. EPA-approved, third-party organizations specify minimum requirements as part of the pellet fuel certification process. Also, in this final action, EPA intends to finalize its decision regarding the proposed changes to the NSPS that would allow retailers to continue selling Step 1-certified residential wood heating devices beyond the May 15, 2020, Step 2 compliance date.
