Issue Overview

HPBA has supported reasonable standards for wood and pellet-fueled appliances to burn more cleanly and efficiently for more than 30 years and worked closely with the Environmental Protection Agency (EPA) to achieve these results. All of today's low-emission woodburning appliances produce significantly less smoke and particulate emissions than older products. Hearth manufacturer and retailer members have benefited from HPBA's efforts, and homeowners have enjoyed new technologies to conserve energy and burn cleaner.

Additional Consumer Information


May 2019 Update 

The Environmental Protection Agency (EPA) still has not published a final rule regarding sell-through for Step 1 appliances beyond the May 15, 2020 effective date – when only Step 2 appliances can be sold under the New Source Performance Standard (NSPS). HPBA continues to encourage all members to operate their businesses with the May 15, 2020 deadline and requirements in mind.

What You Need to Know 

  • The EPA updated the NSPS for New Residential Wood Heaters in March 2015, which was the first update to the rule for woodstoves since 1988. Wood and pellet stoves were required to meet new emission targets, and hydronic heaters and forced-air furnaces became newly-regulated
  • Step 1 of the NSPS came into effect May 15, 2015 and Step 2 will come into effect May 15, 2020.
  • HPBA has significant concerns about the lack of sell-through time for EPA-certified products that meet today’s Step 1 standards but don’t yet meet the Step 2 requirements.
  • On November 30, 2018, the EPA published a Notice of Proposed Rulemaking (NPRM) proposing a sell-through period of two years, until May 15, 2022, for the sale of Step 1 hydronic heaters and furnaces, but not for wood and pellet stoves.
