month period. Table 3.3 lists all TSCA Incinerator emission limits that include those pollutant parameters
associated with Figs. 3.6 through 3.8. All graphical information is based on the allowable rates identified
in the TSCA Incinerator air permit. Actual emissions are conservatively calculated using removal
efficiencies as determined from the most recent permit-required air test or other previously approved
compliance demonstration test.
All reported emission data for the TSCA Incinerator were within all permitted limits. For criteria
pollutants, the highest emissions result against the permitted limit and based on an annualized comparison
was mercury (Hg) at 29.6%. Emissions of the combination of lead (Pb) and cadmium (Cd) were 23.3% of
the permitted limit. The highest emissions result of any other regulated pollutant was for carbon
monoxide (CO) at 19.3%.
The CNF air stripper is the only other ETTP air pollutant source under BJC authority that is permitted
for non-radionuclide emissions. All process data records and the calculated maximum VOC emission rate
for the CNF air stripper were within permitted limits for 2009. The calculated maximum VOC emission
rate was only 0.09 lb/hr as compared to the permitted limit of 1.0 lb/hr.
ETTP operations released airborne pollutants from a variety of other minor pollutant emitting
sources, such as stacks, vents, and fugitive and diffuse activities. With the exception of the TSCA
Incinerator and the CNF air stripper, all other stack and vent emissions are calculated as allowed based on
their low emissions to document the verification of their minor source permit exempt status under all
applicable state and federal regulations. Compliance of fugitive and diffuse sources is demonstrated based
on environmental measurements. The ETTP Ambient Air Quality Monitoring Program is designed to
provide environmental measurements and to accomplish the following:
• Track long term trends of airborne concentration levels of selected air contaminant species.
• measure the highest concentrations of the selected air contaminant species that occur in the vicinity of
ETTP operations, and
• evaluate the impact of air contaminant emissions from ETTP operations on ambient air quality.
