Well, actually in my area I do not need an afterburner due to the small size of my roaster, " E-MAIL From: Northwest Clean Air Agency

Dear Troy,
Thank you for stopping by this morning to inquire about new source review (NSR) approval and permitting requirements. You requested a NSR determination for a single, Dietrich Model IR-3FM batch coffee roaster (
http://www.diedrichroasters.com/ir3.html). This roaster has a 25 lb/hour roasting capacity and uses 12,000 Btu/hour of propane. Based on potential to emit calculations using emission factors from EPA AP-42 for coffee roasting and propane combustion, this unit would not be required to submit a Notice of Construction or be required to proceed through the NSR process in accordance with Northwest Clean Air Agency (NWCAA) Regulation Section 300, before operating in our jurisdiction. Please understand that this determination is based on the information you have submitted and emission estimates that are currently available. In addition, Section 300 includes a Control Officer’s (Director’s) discretionary provision that allows the agency to require a new source to go through NSR based on “the nature of air pollution emissions from the stationary source and its potential effect on health, economic and social factors, or physical effects on property”. Because coffee roasters have the potential to cause odor problems in an area, the agency may choose to exercise this provision, especially if odor complaints are received from the public.
Thank you for your interest in understanding and complying with applicable air pollution rules and regulations.
Sincerely,
Dan Mahar, PE

And having said that if ANYONE complained enough to the clean air folks would make me comply with code due to nuisance complaints, not the actual emissions.
