How will the EPA’s 2020 NSPS Regulations affect you?

Phase 1 of the NSPS went into effect in March of 2015 and outlawed any woodstoves that produced more than 4.5 grams of emissions per hour. Most manufacturers in the industry were able to meet this standard by having their stoves retested and relabeled. Phase 2, howev- er, reduces it down to 2.5 grams of emissions per hour and is not as easy to meet. A lot of stove companies are adding a catalyst to their fireboxes which helps eliminate emissions, but makes the stove less user-friendly, and higher maintenance. Other stoves simply got discontin- ued because of the costs of redesigning and retesting their firebox.
