6. Type of Fuel

Wood waste and natural gas.

7. Type and Quantity of Emissions

Emission increases due to modification:

CO = 1612.0 TPY

Modification is major for CO only, thus only the CO emissions need to be addressed in the BACT analysis. Modification consists of an increase in the allowable CO emissions from the wood-fired Stoker boiler from 100 lbs/hr to 468 lbs/hr, due to an outdated emission factor. Actual CO emissions would not change. Area is nonattainment for PM-10.
