Emission LimitsWood Fired Electric
Generating Units
EBC Seminar
October 28, 2005
Recovering Renewable Energy from Construction and Demolition Debris Wood
MassDEP 2
Current MassDEP requirement for Emission Limits Case-by-case determination
BACT LAER
Limits in regulations (PM, NOx, opacity)
MassDEP 3
Review of Impacts
Will not exceed NAAQSs Will not exceed AALs/TELs Will not cause a condition of Air
Pollution (e.g. noise, odor, dust)

Next Steps
Should the standards be input or output standards.
Decide on standards, averaging time, testing and monitoring.
