| Notes | Expressed as NO2. For large and small wall-fired boilers with SNCR control, apply a 24% reduction to the appropriate NOx emission factor. For tangential-fired boilers with SNCR control apply a 13% reduction to the appropriate NOx emission factor. Pre-NSPS. NSPS=New Source Performance Standard as defined in 40 CFR 60 Subparts D and Db. Post-NSPS units are boilers with greater than 250 MMBtu/hr of heat input that commenced construction modification, or reconstruction after August 17, 1971, and units with heat capacities between 100 and 250 MMBtu/hr that commenced construction modification, or reconstruction after June 19, 1984. | ||
| Multiple Factor Info |
2 duplicate factors.
This one is different because... Factor is for a Pre-NSPS boiler. |
