In this action, the Environmental Protection Agency (EPA) is soliciting comment on several aspects of the 2015 Standards of Performance for New Residential Wood Heaters, New Residential Hydronic Heaters and Forced-Air Furnaces (2015 NSPS) in order to inform future rulemaking to improve these standards and related test methods. This action does not propose any changes to the 2015 NSPS, but does take comment on a number of aspects of the rule, including the compliance date for the Step 2 emission limits, Step 2 emission limits for forced- air furnaces, hydronic heaters and wood heaters, Step 2 emission limits based on weighted averages versus individual burn rates, transitioning to cord wood certification test methods, compliance audit testing, third-party review, electronic reporting tool, and warranty requirements.
