(i) For pulverized coal-fired boilers with an FGD system, total condensable organic PM10 emissions factor is 0.004 lb/MMBtu based on AP-42, Table 1.1-5. 

(g) H2SO4 emissions are based on "Estimating Total Sulfuric Acid Emissions from Stationary Power Plants," EPRI, Technical Update, March 2008 and Hardman et al., 1998. For coal-fired boilers, H2SO4 emissions are determined from "(Q)(98.06/64.04)(F1+S2)(F2)" where Q is the uncontrolled SO2 

emission rate (in lb/hr, calculated from heat rate, fuel S content, and 95% of fuel sulfur converted to SO2), F1 is the fuel factor (0.00111 for western bituminous coal), and F2 is the product of the control factors (0.9 for an air preheater, 0.65 for a venturi scrubber, and 0.10 for a baghouse or cold-side 

wet ESP). EPA revised air preheater factor to 0.36 based on EPRI 2010 update.

(h) H2SO4 emissions are based on "Estimating Total Sulfuric Acid Emissions from Stationary Power Plants," EPRI, Technical Update, March 2008 and Hardman et al., 1998. For coal-fired boilers, H2SO4 emissions are determined from "(Q)(98.06/64.04)(F1+S2)(F2)" where Q is the uncontrolled SO2

(i) For pulverized coal-fired boilers with an FGD system, total condensable organic PM10 emissions factor is 0.004 lb/MMBtu based on AP-42, Table 1.1-5. 

(c) Baseline NOx, SO2 and filterable PM emissions are based worst-case daily emissions received on March 2, 2007 and revised April 26, 2007. EPA Revised to take 2001 max NOx for units 1, 2, 3, 5

(f) Elemental carbon is 3.7% of fine PM based on the best estimate for electric utility coal combustion in Table 6 of “Catalog of Global Emissions Inventories and Emission Inventory Tools for Black Carbon”, William Battye and Kathy Boyer, EPA Contract No. 68-D-98-046, January 2002.

(g) H2SO4 emissions are based on "Estimating Total Sulfuric Acid Emissions from Stationary Power Plants," EPRI, Technical Update, March 2008 and Hardman et al., 1998. For coal-fired boilers, H2SO4 emissions are determined from "(Q)(98.06/64.04)(F1+S2)(F2)" where Q is the uncontrolled SO2 emission 

rate (in lb/hr, calculated from heat rate, fuel S content, and 95% of fuel sulfur converted to SO2), F1 is the fuel factor (0.00111 for western bituminous coal), and F2 is the product of the control factors (0.9 for an air preheater, 0.65 for a venturi scrubber, and 0.10 for a baghouse or cold-side wet ESP). EPA
