1.0 Introduction 

1.1 Objectives 

The Regional Haze Rule requires Best Available Retrofit Technology (BART) for any BART-eligible source that 

‘‘emits any air pollutant which may reasonably be anticipated to cause or contribute to any impairment of 

visibility” in any mandatory Class I federal area. Pursuant to federal regulations, states have the option of 

exempting a BART-eligible source from the BART requirements based on dispersion modeling demonstrating

that the source cannot reasonably be anticipated to cause or contribute to visibility impairment in a Class I 

area. In addition, the Environmental Protection Agency (EPA) has promulgated a rule allowing states subject 

to the Clean Air Interstate Rule (CAIR) to determine that CAIR satisfies the BART requirements for SO2 and 

NOx for electric generating units (EGUs). Feedback from the Georgia Environmental Protection Division 

indicates that CAIR satisfies BART for SO2 and NOx for EGUs. Therefore, this modeling report focuses on 

performing the BART modeling analysis for particulate matter (PM) only. 

Units 6 and 7 at Plant Yates, located near Newnan, which are owned and operated by Georgia Power 

Company, have been identified as a BART-eligible source. The modeling procedures outlined in the sourcespecific BART modeling protocol for Plant Yates were used to determine whether the source is subject to 

BART requirements (exemption modeling). The modeling procedures are consistent with those outlined in the 

updated final VISTAS common BART modeling protocol (dated December 22, 2005, revision 3 – July 18, 

2006), available at http://www.vistas-sesarm.org/BART/BARTModelingProtocol_rev3_18Jul2006.pdf. This 

source-specific BART modeling protocol references relevant portions of the common VISTAS modeling 

protocol. 

1.2 Location of source vs. relevant Class I Areas 

The Georgia Environmental Protection Division, which is in charge of the state’s BART program, has 

determined that Units 6 and 7 at Plant Yates are BART-eligible for PM. Figure 1-1 shows a plot of Plant Yates 

relative to nearby Class I Areas. There are five Class I areas within 300 km of the plant: Cohutta (156.3 km), 

Great Smoky Mountains (241.5 km), Joyce Kilmer (228.2 km), Shining Rock (278.3 km), and Sipsey (239.6 

km). The BART exemption modeling was conducted for these Class I areas in accordance with the referenced 

VISTAS common BART modeling protocol and the procedures described in the source-specific BART 

modeling protocol.

2.0 Source description and emissions data 

2.1 Unit-specific source data 

The emissions data used to assess the visibility impacts at the Class I areas within 300 km of Plant Yates are 

discussed in this section. The Georgia Environmental Protection Division has indicated that CAIR will satisfy 

BART for EGUs for SO2 and NOx. Therefore, this BART exemption modeling analysis focuses only on PM10. 

Since various components of PM10 emissions have different visibility extinction efficiencies, the PM10

emissions are divided, or “speciated,” into several components (VISTAS common protocol Sections 4.3.3 and 

4.4.2). The VISTAS protocol (Section 5) allows for the use of source-specific emissions and speciation factors 

and/or default values from AP-42. The PM10 emissions and speciation approach that were used for the 

modeling is indicated below. Where default speciation values are used, the data represents a unit where 

current (baseline) emission controls include electrostatic precipitators (ESPs), but no post-combustion NOx or 

SO2 control equipment exists. 

• Total PM10 is comprised of filterable and condensable emissions. 

• Baseline filterable PM10 emissions are based on the highest stack test for the most recent 3-year 

period (2003-2005). This stack test is combined with the highest 24 hour heat input value for this 

period from CEMS data to calculate the “maximum 24 hour average emission rate” as required by the 

VISTAS protocol. 

• Filterable PM10 has been subdivided by size category consistent with the default approach from AP-42 

Table 1-1.6, and as noted on pages 43 and 44 of the VISTAS common BART modeling protocol. The 

AP-42 Table 1-1.6 specifies for the emission controls indicated above that 55.6% of filterable PM10

emissions is coarse (greater than 2.5 microns in size) and 44.4% is fine. Of the fine portion, 3.7% is 

elemental carbon and the remainder is inorganic fine particulates (soil). 

• Condensable PM10 consists of inorganic and organic compounds. The inorganic portion is by default 

assumed to be H2SO4, although other non-sulfate inorganic condensables could be present. The 

organic portion is modeled as organic aerosols. 

• Baseline H2SO4 emissions are calculated consistent with the method used by Georgia Power to derive 

these emissions for TRI purposes. This approach assumes that the H2SO4 emissions released from 

the stack are proportional to SO2 emissions from combustion and are dependent on the fuel type and 

the removal of H2SO4 by downstream equipment (i.e., ESP and air heater). For eastern bituminous 

coal the baseline H2SO4 release rate is in the range of 0.3 to 0.8% of the SO2 emissions. Appendix A 

of the site-specific modeling protocol provides the basis for the site-specific values used. 

• Baseline emissions of condensable organics (the remaining portion of condensable PM10) are derived 

based on the supporting field observational information in Appendix B of the site-specific modeling 

protocol and is estimated as 0.32% of SO2 emitted. 

• Coarse filterable particles (between 2.5 and 10 microns in size) will be modeled with a geometric mass

mean diameter of 5 microns, while fine filterable and all condensable particles will be modeled with a

geometric mass mean diameter of 0.48 microns, consistent with the CALPUFF default value for fine 

particles. The geometric standard deviation for both fine and coarse particles will be set to 2 microns, 

consistent with the CALPUFF default value. The 0.48 micron diameter value for fine particles comes 

from the default values in sample input files presented on the TRC web site. There is no default 

value presented for the coarse particles on the TRC web site. However, since 5 is the geometric 

mass mean diameter of 2.5 and 10 (the bounds of coarse particle sizes), it is a reasonable estimate 

for the geometric mass mean diameter for that class of particles. 

In practice, CALPUFF allows for the user to input certain components of PM10 as separate species and 

separate sizes, which will result in more accurate wet and dry deposition velocity results and also more

accurate effects on light scattering. As noted above, the particle size distribution information is provided in 

AP-42 Table 1-1.6, and will be used for the BART exemption modeling. 

Table 2-1 provides a summary of the modeling emission parameters used in the BART CALPUFF modeling, 

consistent with the source emissions data presented in Appendices A and B of the site-specific modeling 

protocol for the baseline. All of the emissions in Table 2-1 were derived from CEMS data for the 2003 to 2005 

period and represent the maximum 24-hour average lb/hr rates (excluding days where startup, shutdown, or 

malfunctions occurred). For NOx and SO2 the values are directly from CEMS. Filterable PM10 emissions were 

calculated using the highest stack test over the 2003 to 2005 period and multiplying these values times the 

maximum 24-hour average heat input derived from CEMS. These values were then adjusted using AP-42 

factors from Table 1.1-6 that indicate that PM10 is 67% of total PM for a pulverized coal unit with an ESP. PM10

speciation was then performed as indicated above such that total Filterable PM10 is made up of Coarse Soil 

plus total Fine PM and total Fine PM is made up of Fine Soil plus Elemental Carbon (EC).

3.0 Presentation of modeling results 

The exemption modeling results are provided in Table 3-1, and Appendix A lists delta-deciview results for the 

top 20 days for each year modeled and the top 25 days for the overall three years at each Class I area. The 

table indicates that both the 8th highest day’s impacts for each year and the 22nd highest day’s impacts over all 

three years are below 0.5 delta-dv. These results demonstrate that Plant Yates’ PM10 emissions do not cause 

or contribute to visibility impairment. Therefore, the source is not subject to BART for PM10, and no further 

BART analysis is required. 

Electronic data related to this application are provided on the attached disk. They include all input (INP) and 

list (LST) files.
