The New Source Performance Standards are Coming
Yesterday, an industry friend of mine let me know that the EPA had informed him that the New Source Performance Standards for-wood fired residential equipment will be released today.
I haven’t seen the pre-publication version as I post this blog, but as he pointed out, it very convenient for industry stakeholders to get their hands on these documents prior to publication in the Federal Register, because it gives them additional time to review before the comment period begins.
In this rule, pellet-fueled appliances will be explicitly covered (in the 1988 rule, pellet stoves were not named). Some manufacturers were certified under the standards, while others avoided EPA certification through the fuel-to-air ratio exemption.
As a story written by a colleague of mine points out, the pellet industry has long anticipated the new rule and worked in advance toward getting two key components in place—testing methods and pellet standards.
And, the new standards will be much tighter than the old, which required residential wood stove particulate emissions be less than 7.5 grams per hour (g/hr) for noncatalytic wood stoves and 4.1 g/hr for catalytic.
I highly recommend reading “The Devil’s in the Details” by Pellet Mill Magazine Managing Editor Sue Retka Schill for an in-depth report on the history and future of the NSPS.
I’m going to keep this post short for now, but stay tuned for an update.
