NSPS for Residential Wood Heaters
The New Source Performance Standards for hydronic heaters, wood-burning forced-air furnaces, pellet stoves, and other wood heaters was published on March 16, 2015. This rule sets standards for previously unregulated heaters, and updates standards for new, adjustable-rate woodstoves. However, the ruling gives manufacturers until the end of 2015 to sell any inventory that does not meet these standards. With 2015 quickly coming to a close, it will not be long before all new wood heaters sold in the above categories will have to pass an EPA-approved compliance test.
The ruling focuses on PM emission limits that are phased in two steps. The first is a less stringent 2015 limit (2016/17 for forced air furnaces) and a secondary, more strict limit by 2020. The EPA estimates that the rule will yield $74 to $165 in benefits for every dollar spent on compliance. The EPA also encourages owners with older, less clean wood burning heaters to replace them with newer, cleaner options.
