1. EXECUTIVE SUMMARY

This report is a revision to “BART Five Factor Analysis” submitted to ADEQ on February 21, 2013 

and is being submitted to provide a comprehensive document that encompasses the determination of 

the Best Available Retrofit Technology (BART) for Entergy Arkansas, Inc.’s (Entergy’s) BARTaffected electric generating units (EGUs) at the White Bluff including changes made in response to

EPA’s comments and suggestions on the previous submittal. The BART determination for each 

pollutant has not changed. 

Entergy operates three BART-affected EGUs at White Bluff: two coal-fired primary boilers (SN-01 

and SN-02) and one fuel oil-fired auxiliary boiler (SN-05). The coal-fired boilers are identical 

tangentially-fired boilers with a maximum net power rating of 850 MW each and a nominal heat input 

capacity of 8,950 million British thermal units per hour (MMBtu/hr) each. The boilers burn subbituminous or bituminous coal1 as the primary fuel and No. 2 fuel oil or biofuel as a start-up fuel. 

SN-01 and SN-02 are currently equipped with electrostatic precipitators (ESPs). 

The Auxiliary Boiler, SN-05, is a 183 MMBtu/hr auxiliary boiler burning No. 2 fuel oil or biodiesel 

as its only fuel types. The purpose of the Auxiliary Boiler is to provide steam for the start-up of the 

two primary boilers, SN-01 and SN-02. There is no emissions control equipment connected to the 

Auxiliary Boiler. Typically, the Auxiliary Boiler is only used in the rare instance when both of the 

main boilers are not operating.

Based on modeling performed for this analysis, cumulative emissions of nitrogen oxides (NOX), 

sulfur dioxide (SO2), and particulate matter with a mass mean diameter smaller than ten microns 

(PM10) from SN-01, SN-02, and SN-05 are predicted to cause or contribute greater than 0.5 delta 

deciviews (∆dv) of visibility impairment in four (4) Class I Areas: Caney Creek Wilderness (CACR), 

Upper Buffalo Wilderness (UPBU), Hercules Glades Wilderness (HERC), and Mingo Wilderness 

(MING)2, 3. A summary of the modeled visibility impairment attributable to SN-01, SN-02, and SN05 based on default natural conditions is provided in Table 1-1. The visibility impairment 

summarized in Table 1-1 is based on modeling conducted by Trinity Consultants (Trinity) using

emissions data based on a combination of continuous emissions monitoring system (CEMS) data as 

reported to EPA’s Clean Air Markets Database (CAMD), stack testing, and annual emissions 

inventory information as further described in Section 4 of this report.

 

1 SN-01 and SN-02 primarily burn sub-bituminous coal, but are permitted to burn bituminous or sub-bituminous 

coal. Only sub-bituminous coals were burned during the 2001-2003 and 2009-2011 baseline periods evaluated in this 

analysis. 

2 SN-05 does not cause visibility impairment greater than 0.5 Δdv in any Class I area but has been reviewed as 

part of the BART five factor analysis for the site because total impairment from the combined units is greater than 0.5 Δdv 

in at least one Class I area. See Table 4-4. 

3 Sipsey Wilderness was included in the Arkansas Department of Environmental Quality's (ADEQ’s) original 

BART analyses, but is not included in this analysis because the EPA-requested change in meteorological data (to a refined, 

or "NO OBS = 0", dataset; see Section 3 and Appendix B) excludes Sipsey from the modeling domain.

Trinity used the EPA’s BART guidelines in 40 CFR Part 514 and other recent EPA guidance5 to 

determine BART for the boilers. Trinity conducted a five-step analysis to determine BART for SO2

and NOx that included the following:

1. Identifying all available retrofit control technologies;

2. Eliminating technically infeasible control technologies;

3. Evaluating the control effectiveness of remaining control technologies;

4. Evaluating impacts and documenting the results; and

5. Evaluating visibility impacts.

The BART analysis concluded that the installation of a semi-dry FGD system constitutes BART for 

SO2 for both SN-01 and SN-02. The proposed BART emission rate for SO2 is 0.06 lb/MMBtu on a 

rolling 30-day average. Since baseline visibility modeling showed that there is no opportunity for 

visibility improvement attributable to SN-05, because not a single day greater than 0.5 ∆dv is 

associated with SN-05, it is not possible to install control equipment to improve visibility. Therefore, 

no controls is the SO2 BART determination for SN-05. 

The BART analysis concludes that for NOX, the achievement of an emission rate of 0.15 lb/MMBtu 

through the installation and use of low NOX burners and separated overfire air (LNB/SOFA) 

represents BART for SN-01 and SN-02.6 Based on the same logic outlined above for SO2, NOx

controls are not appropriate or required for SN-05. 

 

4 The BART guidelines were published as amendments to the EPA’s Regional Haze Rule (RHR) in 40 CFR Part 

51, Section 308 on July 6, 2005.

5 April 26, 2012, letter from Mr. Guy Donaldson, EPA Region VI, to Mr. Anthony Davis, ADEQ.

6 EPA recently issued a final rule allowing states that are subject to the Cross-State Air Pollution Rule (CSAPR) 

trading program for seasonal NOX to rely on the reductions achieved through that trading program to satisfy the regional 

haze program requirements for units subject to BART. “Regional Haze: Revisions to Provisions Governing Alternatives to 

Source-Specific Best Available Technology (BART) Determinations, Limited SIP Disapprovals and Federal Implementation 

Plans,” 77 Fed. Reg. 33651 (June 7, 2012). On August 21, 2012, the D.C. Circuit in a 2-1 decision vacated CSAPR (EME 

Homer City Generation v. EPA, --F. 3d --, No. 11-1302 (D.C. Cir. 2012)), and the Clean Air Interstate Rule (CAIR) remains 

in effect until a replacement rule, if any, is promulgated. If CSAPR ultimately is upheld and implemented in Arkansas, 

Entergy may rely on CSAPR to satisfy its NOx regional haze obligations at SN-01 and SN-02. Alternatively, if CSAPR is 

vacated and CAIR remains in place, Entergy may rely on CAIR to satisfy its NOx obligations under BART as EPA has 

previously determined that the CAIR season NOx trading program provides greater visibility improvement than BART.

EPA approved a BART determination for PM10 at SN-01 and SN-02 in its March 12, 2012, final rule 

based on the existing ESPs, and established a BART emission rate of 0.1 lb/MMBtu for each boiler.7

2. INTRODUCTION AND BACKGROUND

In the 1977 amendments to the Clean Air Act (CAA), Congress set a national goal to restore national 

parks and wilderness areas to pristine conditions by preventing any future, and remedying any 

existing, man-made visibility impairment. On July 1, 1999, the U.S. EPA published the final 

Regional Haze Rule (RHR). The objective of the RHR is to restore visibility to pristine conditions in 

156 specific areas across the United States known as Class I areas. The CAA defines Class I areas as 

certain national parks (larger than 6,000 acres), wilderness areas (larger than 5,000 acres), national 

memorial parks (larger than 5,000 acres), and international parks that were in existence on August 7, 

1977.

The RHR requires States to set goals that provide for reasonable progress towards achieving natural 

visibility conditions for each Class I area in their state. On July 6, 2005, the EPA published 

amendments to its 1999 RHR, often called the Best Available Retrofit Technology (BART) rule, 

which included guidance for making source-specific BART determinations.8 The BART rule defines 

BART-eligible sources as sources that meet the following criteria: 

1. Have potential emissions of at least 250 tons per year of a visibility-impairing pollutant; 

2. Began operation between August 7, 1962 and August 7, 1977; and

3. Are included as one of the 26 listed source categories in the guidance.

A BART-eligible source is subject to BART if the source is “reasonably anticipated to cause or 

contribute to visibility impairment in any federal mandatory Class I area.” EPA has determined that a 

source is reasonably anticipated to cause or contribute to visibility impairment if the 98th percentile 

visibility impacts from the source are modeled to be greater than 0.5 delta deciviews (∆dv) when 

compared against a natural background.9 Air quality modeling is the tool that is used to determine a 

source’s visibility impacts. 

Once it is determined that a source is subject to BART, a BART determination must address air 

pollution control measures for the source. The visibility regulations define BART as follows:

...an emission limitation based on the degree of reduction achievable through the

application of the best system of continuous emission reduction for each pollutant 

which is emitted by...[a BART-eligible source]. The emission limitation must be 

established on a case-by-case basis, taking into consideration the technology available, 

the cost of compliance, the energy and non air quality environmental impacts of 

compliance, any pollution control equipment in use or in existence at the source, the 

remaining useful life of the source, and the degree of improvement in visibility which 

may reasonably be anticipated to result from the use of such technology.

 

8 The BART guidelines were published as amendments to the EPA’s RHR in 40 CFR Part 51, Section 308.

9 The original modeling for Arkansas sources relied on screening met data and, as such, reviewed the maximum 

impact rather than the 98th percentile impact. Use of the 98th percentile impact based on the use of refined met data (such as 

that used in the modeling conducted as part of this BART analysis) is consistent with both the EPA’s 2005 BART rule and 

the 2005 Central Regional Air Planning Association (CENRAP) BART modeling guidelines. 
Entergy 2-2 Trinity Consultants

BART Analysis – White Bluff

Specifically, the BART rule states that a BART determination should address the following five 

statutory factors:

1. Existing controls;

2. Cost of controls;

3. Energy and non-air quality environmental impacts;

4. Remaining useful life of the source; and

5. Degree of visibility improvement as a result of controls.

Further, the BART rule indicates that the five basic steps in a BART analysis can be summarized as 

follows:

1. Identify all available retrofit control technologies;

2. Eliminate technically infeasible control technologies;

3. Evaluate the control effectiveness of remaining control technologies;

4. Evaluate impacts and document the results; and

5. Evaluate visibility impacts.

A BART determination should be made for each visibility-affecting pollutant (VAP) by following the 

five steps listed above for each VAP.

SN-01 and SN-02 meet the three BART-eligibility criteria described above, and the existing visibility 

impairment attributable to each boiler is greater than 0.5 ∆dv in at least one Class I area. Thus, SN01 and SN-02 are subject to BART. SN-05 does not cause visibility impairment greater than 0.5 ∆dv 

in any Class I area10 but has been reviewed as part of the BART five factor analysis for the site 

because total impairment from the combined units is greater than 0.5 ∆dv in at least one Class I area. 

Details of the existing/baseline emissions and the contribution of the emissions to visibility 

impairment can be found in Section 4. The VAPs emitted by the boilers include NOX, SO2, and PM10

of various forms (filterable coarse particulate matter [PMc], filterable fine particulate matter [PMf], 

elemental carbon [EC], inorganic condensable particulate matter [IOR CPM] as sulfates [SO4], and 

organic condensable particulate matter [OR CPM] also referred to as secondary organic aerosols 

[SOA]). The BART determinations for SO2, NOX, and PM10 can be found in Sections 5, 6, and 7, 

respectively.

3. MODELING METHODOLOGIES AND PROCEDURES

This section summarizes the dispersion modeling methodologies and procedures applied in this 

BART analysis. All dispersion modeling has been conducted using the CALPUFF modeling system, 

consisting of the CALPUFF dispersion model, the CALMET meteorological data processor, and the 

CALPOST post-processing program. These methodologies and procedures are consistent with the 

ADEQ modeling protocol submitted to EPA in June 2012. 

CALPUFF is a multi-layer, multi-species, non-steady-state puff dispersion model, which can simulate 

the effects of time and space varying meteorological conditions on pollutant transport, transformation, 

and removal. CALPUFF uses three-dimensional meteorological fields developed by the CALMET 

model. In addition to meteorological data, several other input files are used by the CALPUFF model 

to specify source and receptor parameters. The selection and control of CALPUFF options are 

determined by user-specific inputs contained in the control file. This file contains all of the necessary 

information to define a model run (e.g., starting date, run length, grid specifications, technical 

options, output options). CALPOST processes concentration, deposition, and visibility impacts based 

on pollutant specific concentrations predicted by CALPUFF. 

3.1 CALMET AND CALPUFF

The CALPUFF data and parameters are based on the 2005 BART modeling guidelines prepared for 

CENRAP. The CALMET data and parameters are based on the modeling protocol included in 

Appendix B. Note that the protocol included in Appendix B summarizes modeling methods and 

procedures that were followed to predict visibility impairment as part of the BART analyses for 

several BART-eligible sources located in Oklahoma, the first of which was Oklahoma Gas & Electric 

in 2007. The CALMET dataset developed per this protocol has been used – and approved by EPA –

numerous times since its development.

3.2 CALPOST

The CALPOST visibility processing completed for this BART analysis is based on the October 2010 

guidance from the Federal Land Managers Air Quality Related Values Workgroup (FLAG).11 

Visibility impairment is quantified using the light extinction coefficient (bext), which is expressed in 

terms of the haze index expressed in deciviews (dv). The haze index (HI) is calculated as follows:















10

(dv) 10 ln bext HI

The impact of a source is determined by comparing the HI attributable to a source relative to 

estimated natural background conditions. The change in the haze index, in deciviews, also referred to 

 

11 The 2010 FLAG guidance, which was issued in draft form on July 8, 2008, and published as final guidance in 

December 2010, makes technical revisions to the previous guidance issued in December 2000.

The Interagency Monitoring of Protected Visual Environments (IMPROVE) workgroup adopted an

new IMPROVE equation). The new IMPROVE equation is as follows:

Visibility impairment predictions relied upon in this BART analysis used the equation shown above. 

The use of this equation is referred to as “Method 8” in the CALPOST control file. The use of 

Method 8 requires that one of five different “modes” be selected. The modes specify the approach for 

addressing the growth of hygroscopic particles due to moisture in the atmosphere. “Mode 5” has 

been used in this BART analysis. Mode 5 addresses moisture in the atmosphere in a similar way as to 

“Method 6”, where “Method 6” is specified as the preferred approach for use with the old IMPROVE 

equation in the CENRAP BART modeling protocol.

CALPOST Method 8, Mode 5 requires the following:

 Annual average concentrations reflecting natural background for various particles and for sea 

salt

 Monthly Relative Humidity (RH) adjustment factors for large and small ammonium sulfates 

and nitrates and for sea salts

 Rayleigh scattering parameter corrected for site-specific elevation

Tables 3-1 to Table 3-4 below show the values for the data described above that were input to 

CALPOST for use with Method 8, Mode 5. The values were obtained from the 2010 FLAG 

guidance.

4. EXISTING EMISSIONS AND VISIBILITY IMPAIRMENT

This section summarizes the existing (i.e., baseline) visibility based on air quality modeling 

conducted by Trinity. 

4.1 NOX, SO2, AND PM10 BASELINE EMISSION RATES

Table 4-1 summarizes the emission rates that were modeled for SO2, NOX, and PM10, including the 

speciated PM10 emissions. The SO2 and NOX emission rates are the highest actual 24-hour emission 

rates based on CAMD data from 2001-2003 for SO2 and from 2009-2011 for NOX

12. The 2001-2003 

period was not used for NOX because that period no longer represents actual operation of the boilers. 

In 2006, Entergy completed the addition of a neural net system and also conducted extensive boiler 

tuning. These projects substantially reduced NOX emissions. Accordingly, there is a real difference 

in operations/emissions between the original baseline period (2001-2003) and current operations such 

that the 2001-2003 time period is not representative of current (and thus future, post-BART) 

operations. The BART regulation, at 40 CFR Part 51, Appendix Y, Section IV.D.4.c, speaks to this 

issue:

The baseline emissions rate should represent a realistic depiction of anticipated annual 

emissions for the source. In general, for the existing sources subject to BART, you will 

estimate the anticipated annual emissions based upon actual emissions from a baseline 

period. When you project that future operating parameters (e.g., limited hours of operation 

or capacity utilization, type of fuel, raw materials or product mix or type) will differ from 

past practice, and if this projection has a deciding effect in the BART determination, then you 

must make these parameters or assumptions into enforceable limitations. In the absence of 

enforceable limitations, you calculate baseline emissions based upon continuation of past 

practice.

Using the emission rates from 2001-2003 for NOX would over-state the emissions reductions from the 

proposed BART control technology. Moreover, using the 2001-2003 NOX emission rates would 

exaggerate the projected visibility improvement in the Class I areas. Thus, updating the NOX

emission rates to represent current, normal operation better comports with the regulations. Entergy 

submitted a determination request to ADEQ on August 23, 2012, to use the 2009-2011 NOX emission 

rates based on CEMS data. ADEQ and EPA determined that using the 2009-2011 NOX emission 

rates is consistent with the BART guidance13. 

The PM10 emission rates are based on emission factors from AP-42 for PM10 filterable and PM 

condensable with a 99.5% control efficiency for ESP applied to the PM10 filterable in conjunction 

with the average coal heat value and average coal % ash from 2009-2011. The emission rates for the 

PM10 species reflect the breakdown of the PM10 determined from the National Park Service (NPS)

4.2 BASELINE VISIBILITY IMPAIRMENT

Trinity conducted modeling to estimate the current visibility impairment attributable to SN-01, SN02, and SN-05 in four Class I Areas: Caney Creek Wilderness (CACR), Upper Buffalo Wilderness 

(UPBU), Hercules Glades Wilderness (HERC), and Mingo Wilderness (MING) using the CALPUFF 

dispersion model.17 Table 4-2, Table 4-3, and Table 4-4 provide a summary of the modeled visibility 

impairment attributable to SN-01, SN-02, and SN-05 respectively, based on the emission rates shown 

in Table 4-1. These tables show the maximum impairment in Δdv, the 98th percentile impacts in Δdv, 

and the number of days with impacts greater than 0.5 Δdv as well as the breakdown by pollutant 

species for the 98th percentile impact.

As BART is determined on a unit-by-unit basis, this baseline modeling is presented to show how the 

BART proposed controls will cause improvement, at least on a relative basis.

All of the CALMET, CALPUFF, and CALPOST modeling files used to generate these results are 

included as part of the electronic files submitted with this document. 

 

14 The NPS Workbook, "PC Dry Bottom ESP Example.xls" updated 03/2006, was obtained from the NPS 

website: http://www.nature.nps.gov/air/Permits/ect/index.cfm. The following parameters were input into the workbook for 

speciation determination: total PM10 emission rate of 118.6 lb/hr, heat value of 8,950 Btu/lb, sulfur content of 0.27% and, 

ash content of 4.87%.

15 The SO2 hourly rates were derived from EPA’s CAMD data for 2001 - 2003. The 2001-2003 max daily rates 

were 183,324 lb/day and 187,802 lb/day for SN-01 and SN-02, respectively. See Appendix D. 

16 The NOX hourly rates were derived from EPA’s CAMD data for 2009-2011. The 2001-2003 max daily rates 

were 72,034 lb/day and 84,658 lb/day for SN-01 and SN-02, respectively. See Appendix D. 

17 Due to an EPA-requested change in meteorological data which excluded Sipsey Class 1 Area from the 

modeling domain, Sipsey was not included in this analysis. See footnote 1, above.

5. SO2 BART EVALUATION

5.1 IDENTIFICATION OF AVAILABLE RETROFIT SO2 CONTROL 

TECHNOLOGIES FOR SN-01 AND SN-02

Sulfur oxides, SOX, are generated during coal combustion from the oxidation of sulfur contained in 

the fuel. SOX emissions are almost entirely dependent on the sulfur content of the fuel and are 

generally not affected by boiler size or burner design. SOX emissions from conventional combustion 

systems are predominantly in the form of SO2. Since SO2 is the predominant sulfur compound 

emitted from SN-01 and SN-02, the BART analysis is specific to emissions of SO2. Reductions in 

emissions of SO2 will reduce visibility impairment by reducing sulfate (SO4) formation. 

Step 1 of the top-down control review is to identify available retrofit control options for SO2. The 

available SO2 retrofit control technologies for SN-01 and SN-02 are summarized in Table 5-1. The 

retrofit controls examined are limited to add-on controls that eliminate SO2 after it is formed, as SN01 and SN-02 currently use a low sulfur fuel and thus would not achieve significant additional 

reductions through alternative fuel supplies comparable to the most efficient add-on controls. The 

available SO2 control technologies are Dry Sorbent Injection (DSI), semi-dry scrubbing, and wet 

scrubbing.

5.2 ELIMINATE TECHNICALLY INFEASIBLE SO2 CONTROL TECHNOLOGIES 

FOR SN-01 AND SN-02

Step 2 of the BART determination is to eliminate technically infeasible SO2 control technologies that 

were identified in Step 1. 

5.2.1 DRY SORBENT INJECTION

Dry sorbent injection involves the injection of a sorbent into the exhaust gas stream where 

SO2 reacts with and becomes entrained in the sorbent. The stream is then passed through a 

particulate control device to remove the sorbent and entrained SO2. The process was 

developed as a lower cost Flue Gas Desulfurization (FGD) option because the mixing of 

the SO2 and sorbent occurs directly in the exhaust gas stream instead of in a separate tower. 

Depending on the residence time, gas stream temperature, and limitations of the particulate 
Entergy 5-2 Trinity Consultants

BART Analysis – White Bluff

control device, sorbent injection control efficiency can range between 40 and 60 percent.18

This control is a technically feasible option for the control of SO2 from SN-01 and SN-02.

5.2.2 SEMI-DRY SCRUBBER

There are various designs of semi-dry scrubbing; or fuel gas desulfurization (FGD);

systems, including the Spray Dryer Absorber (SDA) and Circulating Dry Scrubber (CDS) 

designs. In the SDA design, a fine mist of lime slurry is sprayed into an absorption tower 

where the SO2 is absorbed by the slurry droplets. The absorption of the SO2 leads to the 

formation of calcium sulfite and calcium sulfate within the droplets. The liquid-to-gas 

ratio is such that the heat from the exhaust gas causes the water to evaporate before the 

droplets reach the bottom of the tower. This leads to the formation of a dry powder which 

is carried out with the gas and collected with a fabric filter. 

In the CDS process, the flue gas is introduced into the bottom of a reactor vessel at high 

velocity through a venturi nozzle; the exhaust is mixed with water, hydrated lime, recycled 

flyash and CDS reaction products. The intensive gas-solid mixing that occurs in the 

reactor promotes the reaction of sulfur oxides in the flue gas with the dry lime particles. 

The mixture of reaction products (calcium sulfite/sulfate), unreacted lime, and fly ash is 

carried out with the exhaust and collected in an ESP or fabric filter. A large portion of the 

collected particles is recycled to the reactor to sustain the bed and improve lime utilization. 

Semi-dry scrubbing control efficiencies range from 60 to 95 percent,

19 and is a technically 

feasible option for the control of SO2 from SN-01 and SN-02.

5.2.3 WET SCRUBBER

Wet scrubbing involves scrubbing the exhaust gas stream with slurry comprised of lime or 

limestone in suspension. The process takes place in a wet scrubbing tower located 

downstream of a PM control device such as a fabric filter or an electrostatic precipitator 

(ESP) to prevent the plugging of spray nozzles and other problems caused by the presence 

of particulates in the scrubber. Similar to the chemistry illustrated above for spray dryer 

absorption, the SO2 in the gas stream reacts with the lime or limestone slurry to form 

calcium sulfite and calcium sulfate. Wet lime scrubbing is generally capable of achieving 

80-95 percent control.20 Higher control efficiencies may be achieved in certain 

applications. This control is a technically feasible option for the control of SO2 from SN01 and SN-02.

EPA has recently suggested the control from wet scrubbing can achieve emissions 

reductions of up to 97%. Engineering evaluations conducted on Unit 1 and 2 by Sargent & 

Lundy (S&L) suggest that a control efficiency of up to 97% may be achievable through the 

application of wet scrubbing for higher-sulfur coals. However, as no vendor guarantee for 

greater than 95% control from wet scrubbing was available, Entergy cannot confidently 

rely on this level of control specific to SN-01 and SN-02. Moreover, Entergy has not 

received any assurances from vendors or its engineering consultant, S&L, of achieving 

such a level on a consistent, 30-day average basis.

5.3 RANK OF TECHNICALLY FEASIBLE SO2 CONTROL OPTIONS BY 

EFFECTIVENESS FOR SN-01 AND SN-02

The third step in the BART analysis is to rank the technically feasible options according to their 

effectiveness in reducing the VAP. Table 5-2 provides a ranking of the control levels for the controls 

listed in the previous section.

TABLE 5-2. CONTROL EFFECTIVENESS OF TECHNICALLY FEASIBLE SO2 CONTROL 

TECHNOLOGIES

Control Technology Estimated Control 

Efficiency 

Wet Scrubber 80-95%21

Semi-Dry Scrubber 60-95%

Dry Sorbent Injection 40-60%

5.4 EVALUATION OF IMPACTS FOR FEASIBLE SO2 CONTROLS FOR SN-01 AND 

SN-02

The fourth step in the BART analysis is the impact analysis where the impacts for those control 

options deemed feasible in Step 2 are evaluated. This analysis is typically conducted to demonstrate 

that a control technology that is more effective than another technology does not constitute BART. 

The BART determination guidelines list the four factors to be considered in the impact analysis:

▲ Cost of compliance

▲ Energy impacts

▲ Non-air quality impacts; and

▲ The remaining useful life of the source

Wet and dry scrubbing are the most effective technologies at reducing SO2. As shown in Table 5-2,

both technologies can achieve 95 percent reduction in SO2. 

 

21 Estimated efficiency for wet FGD for low-sulfur coals typically combusted at White Bluff. Higher efficiencies 

are achievable for wet FGD when burning higher-sulfur coal, but may not be achievable for the low-sulfur coal typically 

combusted at SN-01 and SN-02. 
Entergy 5-4 Trinity Consultants

BART Analysis – White Bluff

Site-specific specifications from S&L indicate that semi-dry scrubbing can achieve an outlet rate of 

0.06 lb/MMBtu on a 30-day rolling average basis. Entergy believes that semi-dry scrubbing 

represents a superior technology in comparison to wet scrubbing, thus the majority of research for this 

analysis has been focused on this control option. Information from S&L also indicate that wet 

scrubbing may be able to achieve an outlet rate of 0.04 lb/MMBtu on a 30-day rolling average 

basis.

22 These emission levels represent reductions of 95% for semi-dry scrubbing and 97% for wet

scrubbing when applied to the facility’s current maximum allowable SO2 emission rate of 1.2 

lb/MMBtu. Notwithstanding a lack of vendor assurances, for the purposes of this analysis, wet 

scrubbing has been evaluated at an outlet SO2 emission rate of 0.04 lb/MMBtu. 

5.4.1 COST OF COMPLIANCE

Control Costs

The capital costs were annualized over a 30-year period and then added to the annual 

operating costs to obtain the total annualized costs. The details of the cost effectiveness 

calculations are provided in Appendix A of this report. 

The capital and direct operating and maintenance (O&M) costs of a semi-dry scrubber used 

in the cost effectiveness calculations were based on vendor estimates. The indirect 

operating costs such as property tax and insurance are based on calculation methods 

published in the sixth edition of the EPA’s Air Pollution Cost Control Manual for wet acid 

gas absorber systems. The capital and O&M costs of a wet scrubber used in the cost 

effectiveness calculations are based on vendor estimates for a system estimated to achieve 

97% control for an inlet SO2 rate of 2.0 lb/MMBtu (0.06 lb/MMBtu) and calculation 

methods published in the sixth edition of the EPA’s Air Pollution Cost Control Manual. 

The costs for a system capable of achieving equivalent control with an inlet SO2 rate of 1.2 

lb/MMBtu or 0.04 lb/MMBtuwould be approximately 5 to 6 percent higher. The capital 

cost associated with a wet scrubber system is considerably higher than for a semi-dry 

scrubber system. 

Annual Tons Reduced

The annual tons reduced that were used in the cost effectiveness calculations were 

determined by subtracting the estimated controlled annual emission rate from the baseline 

annual emission rate. The baseline annual emission rate was the average rate from 2001-

2003, as reported by Entergy in their air emission inventories. The controlled annual 

emission rates were based on the lb/MMBtu levels believed to be achievable for the control 

technologies multiplied by the future annual heat input. The future annual heat input is 

based on the average hourly heat input from CAMD for 2001 to 2003 multiplied by the 

average annual operating hours from 2001-2003 for each boiler. 

Cost Effectiveness

 

22 The cost estimate from S&L for a wet FGD system represents a system estimated to achieve 97% control for an 

inlet SO2rate of 2.0 lb/MMBtu (0.06 lb/MMBtu) S&L has indicated the cost for a system capable of achieving 97% control 

for an inlet SO2rate of 1.2 lb/MMBtu (0.04 lb/MMBtu) would be 5 to 6 percent higher. Entergy has not received any 

guarantee that an outlet SO2 emission rate of 0.04 lb/MMBtu is consistently achievable for SN-01 or SN-02. 
Entergy 5-5 Trinity Consultants

BART Analysis – White Bluff

The cost effectiveness in dollars per ton of SO2 reduced was determined by dividing the 

annualized cost of control by the annual tons reduced. Table 5-3 indicates that the cost 

effectiveness of semi-dry scrubber at an SO2 rate of 0.06 lb/MMBtu is approximately 

$3,281 per ton of SO2 removed for SN-01 and $3,778 per ton of SO2 removed for SN-02. 

The incremental costs for wet scrubbing at 0.04 lb/MMBtu over semi-dry scrubbing at 0.06 

lb/MMBtu are $22,756/ton for SN-01 and $23,191/ton for SN-02. As documented in 

Section 5.5 below, the additional cost of wet FGD is not justified in light of the negligible 

improvement in visibility impacts associated with this control technology.

2. The incremental visibility improvement for semi-dry scrubbing is the maximum visibility improvement in the 98th percentile impact compared to baseline (See Tables 5-5 and 5-6). The incremental visibility 

improvement for wet scrubbing is the difference between the maximum improvement due to wet scrubbing less the maximum visibility improvement from dry scrubbing (See Tables 5-5 and 5-6).

5.4.2 ENERGY IMPACTS AND NON-AIR QUALITY IMPACTS

As illustrated in Table 5-3 and in Section 5.5 below, wet scrubbing is expected to achieve 

approximately the same level of visibility improvement as the proposed dry scrubbing 

technology. However, the negative non-air quality environmental impacts are greater with 

wet scrubbing systems. Such impacts include a potential increase in particulate and 

sulfuric acid (H2SO4) mist emissions. In addition, wet scrubbers require increased water 

use and generate large volumes of wastewater and solid waste/sludge that must be 

managed and/or treated. This places additional burdens on the wastewater treatment and 

solid waste management capabilities. Moreover, if wet scrubbing produces calcium sulfite 

sludge, the sludge will be water-laden, and it must be stabilized for landfilling. Wet 

scrubbing systems require increased power requirements and increased reagent usage over 

dry scrubbers. Thus, from an overall environmental perspective, dry scrubbing is superior 

to wet scrubbing. 

5.4.3 REMAINING USEFUL LIFE

The remaining useful life of SN-01 and SN-02 does not impact the annualized capital costs 

for either semi-dry scrubbing or wet scrubbing because the useful life of the units is 

anticipated to be at least as long as the capital cost recovery period, which is 30 years based 

on the recovery period documented for wet scrubbers for acid gas in the EPA’s Control 

Cost Manual.

5.5 EVALUATION OF VISIBILITY IMPACT OF FEASIBLE SO2 CONTROLS FOR 

SN-01 AND SN-02

A final impact analysis was conducted to assess the visibility improvement achieved by comparing 

the impacts associated with the baseline emission rates to the impacts associated with the controlled 

emission rates. Section 4 of this report documents the existing visibility impairment attributable to 

SN-01 and SN-02. In order to assess the visibility improvement associated with semi-dry and wet 

scrubbing, the controlled emission rates associated with each control technology were modeled using 

CALPUFF. The SO2 emission rates associated with wet and semi-dry scrubbers were calculated as 

follows:

P*HI

= 537.00 lb/hr

Where:

P for wet scrubber = 0.04 lb/MMBtu

P for semi-dry scrubber = 0.06 lb/MMBtu

HI (hourly heat input) = 8,950 MMBtu/hr

Table 5-4 summarizes the lb/hr emission rates that were modeled to reflect the addition of wet and 

semi-dry scrubbers on SN-01 and SN-02. One important thing to note is the ammonium sulfate

emission rate indicated for wet scrubbers is higher than the ammonium sulfate emission rate indicated 

for semi-dry scrubbers. For all PM species other than ammonium sulfate, the NPS speciation 

spreadsheets were relied upon to determine emission rates for PM species. For ammonium sulfate, 

the approach described below was used. The NOX emission rates were modeled at the baseline rates. 
Entergy 5-8 Trinity Consultants

BART Analysis – White Bluff

Sulfur in the fuel reacts with oxygen during the combustion process to form SO2. Some of the SO2 is 

further oxidized to SO3, which is a precursor to sulfuric acid (H2SO4). Sulfuric acid can react with 

ammonia to cause primary emissions of ammonium sulfate. According to both FGD suppliers and 

the EPA, wet scrubbers have less affinity for SO3 and typically capture between 25-50% of the SO3.

23

Since SO3 can lead to the formation of H2SO4, which leads to the formation of ammonium sulfates, 

the higher level of SO3 control for semi-dry scrubbers will result in lower H2SO4 emissions and thus 

lower ammonium sulfate emissions. The ammonium sulfate emission rates for semi-dry scrubbers 

shown in Table 5-4 were determined assuming the reduction in ammonium sulfate (SO4) is 

proportional to the reduction in SO2 from the baseline case to the controlled case (95%). The 

ammonium sulfate emission rates for wet scrubbers shown in Table 5-4 were determined assuming a 

50% reduction in SO4 from the baseline case to the controlled case.

BART Analysis – White Bluff

As shown in Table 5-5 and Table 5-6, based on visibility predictions from the CALPUFF modeling 

system, the operation of a semi-dry scrubber achieving 0.06 lb/MMBtu will result in up to a 0.813

Δdv improvement (depending on the Class I area) to the existing 98th percentile day of visibility 

impairment attributable to SN-01 and up to 0.767 Δdv improvement for SN-02. By comparison, wet 

scrubbing achieving 0.04 lb/MMBtu only adds up to an additional 0.028 Δdv improvement for SN-01 

and up to 0.021 Δdv improvement for SN-02. 

For convenience, Tables 5-7 and 5-8 provide a condensed summary of the predicted improvements to 

visibility impairment alongside the estimated control costs. While the application of wet scrubbing 

may be able to achieve a nominally lower outlet SO2 emission rate, there is essentially no incremental 

visibility benefit of going from semi-dry scrubbing to wet scrubbing. Further, in some cases, 

CALPUFF predicts worse visibility impairment for wet scrubbing as opposed to semi-dry scrubbing. 

This is likely due to the higher SO4 emissions associated with wet vs dry scrubbing. Overall, the very 

small differences in predicted visibility impacts likely fall within the relative accuracy level of 

CALPUFF’s modeling results. Given that wet scrubbing requires a significantly higher capital 

investment and is more expensive from an incremental cost effectiveness standpoint than semi-dry 

scrubbing, it cannot be justified as BART at SN-01 and SN-02. The adverse non-air environmental 

impacts from wet scrubbing also make it a less desirable control technology.

5.6 PROPOSED BART FOR SO2 FOR SN-01 AND SN-02

Entergy is proposing that the SO2 BART emission level for SN-01 and SN-02 be 0.06 lb/MMBtu 

based on the installation and operation of a semi-dry scrubber or whatever technology may become 

available to achieve that level of control. EPA has previously agreed that “this [SDA] technology is 

BART for these two units.”24 Entergy is proposing to meet this limit on a 30-day rolling average 

basis. This emission level provides for a very small compliance margin considering the variability of 

the coal content for the White Bluff units; therefore, the proposed 30-day averaging period and 

compliance demonstration method is critical. Compliance will be demonstrated using data from the 

existing CEMS. 

5.6.1 COMPARATIVE SO2 BART DETERMINATIONS 

EPA has agreed with similar and even less stringent SO2 BART determinations in other states. For 

example, in Oklahoma,25 EPA agreed with the BART determination of 0.06 lb/MMBtu achieved 

through use of dry scrubbers for similar boilers, based on the minimal visibility improvement 

associated with wet vs dry scrubbing.. In Nebraska26 at GGS, BART for SO2 was also determined to 

be 0.06 lb/MMBtu achieved through the use of dry scrubbers. These similar units provide a good 

comparison of emission levels achievable through similar control technology.

Other BART determinations have resulted in higher emission limitations. For example, in 

Alabama,27 a smaller EGU was allowed an emission limitation of 0.47 lb/MMBtu through use of flue 

solvent injection or comparable technologies. In Arizona,28 SO2 BART was determined to be in the 

range of 0.08 – 0.15 lb/MMBtu from existing wet scrubbers. An EGU in Colorado29 has a proposed 

BART emission rate of 0.13 lb/MMBtu through use of dry scrubbing. A lower emission rate of 0.09 

lb/MMBtu was evaluated and determined not reasonable due to the minimal visibility improvement 

projected as compared to the higher costs of scrubbing to meet the lower rate. 

In other determinations, such as Illinois,30 the control technology was not stated in the BART 

determination but the SO2 rate determined to be BART was in the range of 0.11 – 0.23 lb/MMBtu, 

dependent upon boiler type and averaging considerations. SO2 BART in Kansas31 was achieved 

through “scrubbing” with an emission limitation of 0.10 lb/MMBtu for one boiler and through wet 

scrubbing with an emission limitation of 0.15 lb/MMBtu for another. An EGU in Montana32 similar 

to Entergy’s SN-01 and SN-02 has a BART emission rate of 0.08 lb/MMBtu.

5.7 SO2 BART FOR SN-05

Section 4 of this report summarized the baseline visibility impairment attributable to SN-01, SN-02 

and SN-05. Table 4-4 demonstrates that SN-05 does not contribute one day of the visibility 

impairment greater than 0.5 Δdv. Therefore, no controls will be considered BART for SN-05. This 

conclusion is consistent with EPA’s determinations for similar boilers in other states, such as the 

auxiliary boiler at the Basin Electric Power Cooperative’s Leland Olds Station located in North 

Dakota or the auxiliary boiler at the Golden Valley Electric Association’s Healy Power plant in 

Fairbanks, Alaska.

6. NOX BART EVALUATION

6.1 IDENTIFICATION OF AVAILABLE RETROFIT NOX CONTROL 

TECHNOLOGIES FOR SN-01 AND SN-02

Nitrogen oxides, NOX, are produced during fuel combustion when nitrogen contained in both the fuel 

and the combustion air is exposed to high temperatures. The origin of the nitrogen (i.e. fuel vs. 

combustion air) has led to the use of the terms “thermal” NOX and “fuel” NOX when describing NOX

emissions. Thermal NOX emissions are produced when elemental nitrogen in the combustion air is 

exposed to a high temperature zone and oxidized. Fuel NOX emissions are created during the rapid 

oxidation of nitrogen compounds contained in the fuel. 

Nitrogen oxide (NO) is typically the predominant form of NOX from fossil fuel combustion. Nitrogen 

dioxide (NO2) makes up the remainder of the NOX. The formation of NOX compounds in utility 

boilers is sensitive to the method of firing. In tangentially-fired boilers, such as SN-01 and SN-02, a 

single rotating flame is created in the center of the furnace, rather than the discrete flames produced 

by burners in the wall-fired boilers. Tangentially fired boilers typically have lower uncontrolled NOX

emissions than wall-fired boilers. Therefore, baseline NOX emission rates can vary significantly from 

plant to plant due to method of firing as well as several other factors.

Step 1 of the BART determination is the identification of all available retrofit NOX control 

technologies. The available retrofit NOX control technologies are summarized in Table 6-1 for 

SN-01 and SN-02.

NOX emissions controls, as listed in Table 6-1, can be categorized as combustion or post-combustion 

controls. Combustion controls, including flue gas recirculation (FGR), overfire air (OFA) or 

separated OFA (SOFA), and Low NOX Burners (LNB), reduce the peak flame temperature and excess 

air in the furnace which minimizes NOX formation. Post-combustion controls, such as selective 

catalytic reduction (SCR) and selective non-catalytic reduction (SNCR), convert NOX in the flue gas 

to molecular nitrogen and water.

6.2 ELIMINATE TECHNICALLY INFEASIBLE NOX CONTROL TECHNOLOGIES

Step 2 of the BART determination is to eliminate technically infeasible NOX control technologies that 

were identified in Step 1. Control ranges were developed using a combination of literature control 

ranges and efficiencies. Because many controlled emissions rates from literature values were higher 
Entergy 6-2 Trinity Consultants

BART Analysis – White Bluff

than the baseline NOX rate at SN-01 and SN-02, vendor estimates were also used to assist in 

developing the expected emission rates from the known relationships between the control options. 

6.2.1 COMBUSTION CONTROLS

6.2.1.1 FLUE GAS RECIRCULATION (FGR)

FGR uses flue gas as an inert material to reduce flame temperatures. In a 

typical flue gas recirculation system, flue gas is collected from the combustion 

chamber or stack and returned to the burner via a duct and blower. The 

addition of flue gas reduces the oxygen content of the “combustion air” (air + 

flue gas) in the burner. The lower oxygen level in the combustion zone reduces 

flame temperatures, which in turn reduces thermal NOX formation. However, 

vendor-specific review of the White Bluff boilers has concluded that NOX

reduction efficiency data for coal-fired units with FGR are limited. The amount 

of NOX reduction achievable with FGR depends primarily on the fuel nitrogen 

content and amount of FGR used. Generally, FGR is more effective when used 

with low nitrogen content fuels such as natural gas and propane, since FGR is 

more effective in controlling thermal NOX rather than fuel NOX. Industry 

experience with FGR on coal-fired units for steam temperature control has 

shown very high maintenance on the gas recirculation fans due to erosion and 

corrosion. Many of the units with FGR for steam temperature control have 

removed the recirculation fans from service. The NOX control achievable on 

tangentially fired units like White Bluff – Units 1&2 with LNB+OFA has been 

comparable to that of FGR at lower capital and O&M cost. Currently, FGR 

technology is not offered by OEMs for coal-fired units. For these reasons, FGR 

is not a feasible technology for the White Bluff coal-fired units.

6.2.1.2 OVERFIRE AIR (OFA) / SEPARATED OVERFIRE AIR (SOFA)

OFA diverts a portion of the total combustion air from the burners and injects it 

through separate air ports above the top level of burners. Staging of the 

combustion air creates an initial fuel-rich combustion zone with a lower peak 

flame temperature. This reduces the formation of thermal NOX by lowering 

combustion temperature and limiting the availability of oxygen in the 

combustion zone where NOX is most likely to be formed. 

SOFA refers to a system wherein the OFA is injected in a separate wind box 

mounted above the main wind box in order to achieve greater separation from 

the combustion zone resulting in more effective NOX suppression. SOFA as a 

single NOX control technique results in estimated NOX emissions for coal fired 

boilers of approximately 10%,33 or 0.28-0.32 lb/MMBtu from SN-01 and SN02. This control is a technically feasible option for the control of NOX from 

SN-01 and SN-02.

6.2.1.3 LOW NOX BURNERS (LNB)

LNB technology utilizes advanced burner design to reduce NOX formation 

through the restriction of oxygen, lowering of flame temperature, and/or 

reduced residence time. NOX creation rates typically peak at oxygen levels of 

five to seven percent.34 LNB is a staged combustion process that is designed to 

split fuel combustion into two zones. In the primary zone, NOX formation is 

limited by one of two methods. Under staged fuel-rich conditions, low oxygen 

levels limit flame temperatures resulting in less NOX formation. The primary 

zone is then followed by a secondary zone in which the incomplete combustion 

products formed in the primary zone act as reducing agents. Alternatively, 

under staged fuel-lean conditions, excess air will reduce flame temperature to 

reduce NOX formation. In the secondary zone, combustion products formed in 

the primary zone act to lower the local oxygen concentration, resulting in a 

decrease in NOX formation. 

When combined with SOFA, the estimated NOX emission rate is 0.15

lb/MMBtu.35 LNB systems with SOFA are technically feasible for the control 

of NOX from SN-01 and SN-02.

6.2.2 POST COMBUSTION CONTROLS

6.2.2.1 SELECTIVE CATALYTIC REDUCTION (SCR)

SCR refers to the process in which NOX is reduced by ammonia over a 

heterogeneous catalyst in the presence of oxygen. The process is termed 

selective because the ammonia preferentially reacts with NOX rather than 

oxygen, although the oxygen enhances the reaction and is a necessary 

component of the process. The overall reactions are:

4NO + 4NH3 + O2  4N2 + 6H2O

2NO2 + 4NH3 + O2  3N2 + 6H2O

The SCR process requires a reactor, a catalyst, and an ammonia storage and 

injection system. The effectiveness of an SCR system is dependent on a variety 

of factors, including the inlet NOX concentration, the exhaust temperature, the 

ammonia injection rate, and the type of catalyst. When combined with LNB 

and OFA, the estimated NOX emission rate is 0.055 lb/MMBtu.

36 This control 

is a technically feasible option for the control of NOX from SN-01 and SN-02.

6.2.2.2 SELECTIVE NON-CATALYTIC REDUCTION (SNCR)

In SNCR systems, a reagent is injected into the flue gas in the furnace within an 

appropriate temperature window. The NOX and reagent (ammonia or urea)

react to form nitrogen and water. A typical SNCR system consists of reagent 

storage, multi-level reagent-injection equipment, and associated control 

instrumentation. The SNCR reagent storage and handling systems are similar 

to those for SCR systems. However, both ammonia and urea SNCR processes 

require three to four times as much reagent as SCR systems to achieve similar 

NOX reductions. When combined with LNB/OFA, the estimated NOX emission 

rate is 0.13 lb/MMBtu.37 This control is a technically feasible option for the 

control of NOX from SN-01 and SN-02.

6.3 RANK OF TECHNICALLY FEASIBLE NOX CONTROL OPTIONS BY 

EFFECTIVENESS

The third step in the BART analysis is to rank the technically feasible options according to 

effectiveness. Table 6-2 provides a ranking of the control levels for the controls listed in the 

previous section.

TECHNOLOGIES

(lb/MMBtu)

SOFA 0.28-0.32

LNB/SOFA 0.15

LNB/SOFA + SNCR 0.13

LNB/SOFA + SCR 0.055

Current NOX emissions are approximately 0.31 lb/MMBtu from SN-01 and approximately 0.36 

lb/MMBtu from SN-02. Based on evaluations by S&L, it is believed that combustion controls such 

as LNB in combination with SOFA will achieve a NOX level of 0.15 lb/MMBtu for SN-01 and SN02.38 Further, it is believed that the addition of SCR to LNB/SOFA will achieve a NOX level of 

approximately 0.055 lb/MMBtu at each unit and LNB/SOFA + SNCR will achieve a level of 0.13

lb/MMBtu at each unit. 

6.4 EVALUATION OF IMPACTS FOR FEASIBLE NOX CONTROLS 

Step four for the BART analysis is the impact analysis. The BART determination guidelines list four 

factors to be considered in the impact analysis:

▲ Cost of compliance;

▲ Energy impacts;

▲ Non-air quality impacts; and

▲ The remaining useful life of the source.

6.4.1 COST OF COMPLIANCE

The capital costs, operating costs, and cost effectiveness of LNB/SOFA, LNB/SOFA + 

SNCR and LNB/SOFA + SCR were estimated for the cost analysis. 

 

38 EPA established presumptive SO2 and NOX controls for coal-fired EGUs in the BART rule. For dry bottom 

tangentially-fired EGUs, the presumptive NOX limit is 0.15 lb/MMBtu. (Regional Haze Regulations and Guidelines for 

Best Available Retrofit Technology (BART Determinations; Final Rule.”) 77 FR 39134 (July 6, 2005).
Entergy 6-6 Trinity Consultants

BART Analysis – White Bluff

Control Costs

Control costs were calculated using vendor capital and operating cost estimates specific to 

the units. The capital costs were annualized over a 30-year period and then added to the 

annual operating costs to obtain the total annualized costs. 

The details of the capital and operating cost estimates are provided in Appendix A of this 

report. 

Annual Tons Reduced

The annual tons reduced that were used in the cost effectiveness calculations were 

determined by subtracting the estimated controlled annual emission rate from the baseline 

annual emission rate. 

The baseline annual emission rates were the average rates from 2009-2011, as reported by 

Entergy in their air emission inventories. The controlled annual emission rate is based on 

the lb/MMBtu level believed to be achievable from the control technology multiplied by 

the future annual input to the boiler in MMBtu/yr. The future annual heat input is based on 

the average hourly heat input from CAMD for 2001 to 2003 multiplied by the average 

annual operating hours from 2001to 2003 for each boiler. This was the same approach that 

was used to estimate future annual heat input in the review of SO2 controls 

Cost Effectiveness

The cost effectiveness in dollars per ton of NOX reduced was determined by dividing the 

annualized cost of control by the annual tons reduced. An incremental cost analysis was 

also performed to show the incremental increase in costs between LNB/SOFA + SCR and 

an LNB/SOFA system, as well as between LNB/SOFA + SNCR and LNB/SOFA. The 

costs effectiveness analysis is summarized in Table 6-3. 

In the BART guidelines, EPA calculated that for all types of boilers other than cyclone 

boilers, combustion control technology is generally more cost-effective than postcombustion controls. EPA estimates that approximately 75 percent of the BART units 

(non-cyclone) could meet the presumptive NOX limits at a cost of $100 to $1,000 per ton of 

NOX removed based on the use of combustion control technology.39 For the units that 

could not meet the presumptive limits using combustion control technology, EPA estimates 

that almost all of these sources could meet the presumptive limits using advanced 

combustion controls. The EPA estimates that the costs of such controls are usually less 

than $1,500 per ton of NOX removed.40 

Table 6-3 indicates that the cost effectiveness of LNB/SOFA is approximately $400 per ton 

of NOX removed. Installing LNB/SOFA would reduce NOX emissions by more than 50%. 

By contrast, the incremental cost effectiveness of adding SNCR to LNB/SOFA is 

 

39 Id. at 39134-39135.

approximately $10,000/ton per unit. Similarly, the incremental cost of adding SCR to 

LNB/SOFA is approximately $8,000-$8,500/ton per unit. 

Table 6-3 also demonstrates the improvement in the maximum of the 98th percentile 

visibility impairment results due to each control technology. As Table 6-3 clearly shows, 

LNB/SOFA + SNCR offers very little visibility improvement over LNB/SOFA alone

(~0.03 dv). The addition of SCR incrementally improves visibility over LNB/SOFA by 

only approximately 0.1 dv at an annual cost of well over $20,000,000 per unit. Such a 

large cost cannot be justified by the negligible visibility improvement provided by SCR.

2. The incremental visibility improvement for LNB/SOFA is the maximum visibility improvement in the 98th percentile impact compared to baseline (See Tables 6-5 and 6-6). The incremental visibility improvement for LNB/SOFA/SNCR and 

LNB/SOFA/SCR is the difference between the maximum improvement due to LNB/SOFA/SNCR or LNB/SOFA/SCR in the four Class I areas considered in the analysis less the maximum visibility improvement in the four Class I areas from 

LNB/SOFA (See Tables 6-5 and 6-6).

6.4.2 ENERGY IMPACTS & NON-AIR IMPACTS

As noted in Table 6-3 and in Section 6.5 below, SCR and SNCR systems are capable of 

achieving additional NOX mass emission reductions in comparison to combustion controls 

such as LNB/SOFA. However, both SCR and SNCR systems create additional energy 

and/or non-air environmental impacts. SCR and SNCR systems require electricity to 

operate the ancillary equipment. The need for electricity to help power some of the 

ancillary equipment creates a demand for energy that currently does not exist. 

SCR and SNCR can potentially cause significant environmental impacts. The primary 

avenue is related to the storage of ammonia. The storage of aqueous ammonia above 

10,000 lbs is regulated by a risk management program (RMP), since the accidental release 

of ammonia has the potential to cause serious injury and death to persons in the vicinity of 

the release. Additionally, SCR and SNCR will likely also cause the release of unreacted 

ammonia to the atmosphere. This is referred to as ammonia slip. Ammonia slip from 

SCR and SNCR systems occurs either from ammonia injection at temperatures too low for 

effective reaction with NOX, leading to an excess of unreacted ammonia, or from overinjection of reagent leading to uneven distribution; which also leads to an excess of 

unreacted ammonia. Ammonia released from SCR and SNCR systems will react with 

sulfates and nitrates in the atmosphere to form ammonium sulfate and ammonium nitrate. 

Together, ammonium sulfate and ammonium nitrate are the predominant sources of 

regional haze. 

Another environmental impact associated with SCR is the disposal of catalyst waste. To 

maintain NOX-removal effectiveness, the catalyst in an SCR system must periodically be 

cleaned, regenerated, or replaced. Cleaning and regeneration are preferred, but eventually 

the catalyst reaches the end of its useful life and must be replaced. Ideally the exhausted 

catalyst can be recycled for reuse, however, if the condition of the spent catalyst does not 

warrant recycling or a market is unavailable, the old catalyst must be disposed of. Current 

regulatory interpretations indicate spent SCR catalysts are exempted from hazardous waste 

regulation via 40 CFR § 261.4(b)(4) (Bevill Exemption) as flue gas emission control 

wastes. However, ongoing efforts by EPA to increase regulatory oversight of coal 

combustion residuals could alter that exemption, and create the potential that spent SCR 

catalysts would be characterized as hazardous wastes, hence increasing the cost of disposal. 

Regardless of the regulatory treatment of the waste, the disposal creates additional

potential financial and environmental impacts associated with an SCR system.

6.4.3 REMAINING USEFUL LIFE

The remaining useful life of SN-01 and SN-02 are sufficiently long such that it does not 

affect the BART analysis.

6.5 EVALUATION OF VISIBILITY IMPACT OF FEASIBLE NOX CONTROLS 

A final impact analysis was conducted to assess the visibility improvement for existing emission rates 

when compared to the emission rates associated with LNB/SOFA, LNB/SOFA + SNCR and 

LNB/SOFA + SCR. Section 4 of this report documented the existing visibility impairment 

attributable to SN-01 and SN-02. In order to assess the visibility improvement associated with 

LNB/SOFA, SCR and SNCR systems, the NOX emission rates associated with the control systems 

were modeled using CALPUFF. The controlled emission level associated with LNB/SOFA system is 

0.15 lb/MMBtu; the controlled emission level associated with SOFA + SNCR is 0.13 lb/MMBtu; and 

the controlled emission level associated with LNB/SOFA + SCR systems is 0.055 lb/MMBtu for each 

unit. These levels were multiplied by the maximum heat input to derive the hourly emission rates 

used in the modeling. 

Table 6-4 summarizes the NOX emission rates that were modeled to reflect the LNB/SOFA, 

LNB/SOFA + SNCR, and LNB/SOFA + SCR. The emission rates for the other pollutants shown in 

Tables 6-4 are the same as in the baseline modeling.

BART Analysis – White Bluff

In light of the very small incremental visibility benefit and the high marginal cost, SNCR cannot be 

considered BART for either SN-01 or SN-02. As shown in Table 6-5 and Table 6-6, based on 

visibility predictions from the CALPUFF modeling system, the operation of a LNB/SOFA will result 

in up to a 0.176 Δdv improvement (depending on the Class I area) to the existing visibility 

impairment attributable to SN-01 and up to 0.225 Δdv improvement for SN-02. There is essentially 

zero visibility improvement due to including SNCR, with a modeled change of approximately 0.03

Δdv for both units. The addition of SCR would produce a modeled improvement of only 0.103 Δdv 

for Unit 1 and 0.102 Δdv for Unit 2 over LNB/SOFA alone. 

Tables 6-7 and 6-8 provide a condensed summary of these predicted improvements alongside the 

estimated control costs. The incremental benefit of going from LNB/SOFA to either LNB/SOFA + 

SCNR or LNB/SOFA + SCR is clearly not justified. The control technologies are very expensive 

from an initial capital investment and are prohibitively more expensive from an incremental cost 

effectiveness standpoint than LNB/SOFA alone.

6.6 PROPOSED BART FOR NOX FOR SN-01 AND SN-02

If CSAPR ultimately is upheld and implemented in Arkansas, Entergy may rely on CSAPR to satisfy 

its NOX regional haze obligations at SN-01 and SN-02. Alternatively, if CSAPR is vacated and CAIR 

remains in place, Entergy may rely on CAIR to satisfy its NOX obligations under BART as EPA has 

previously determined that the CAIR season NOX trading program provides greater visibility 

improvement than BART.

With full consideration of all five factors outlined by EPA for BART determinations, Entergy 

proposes a BART emission level of 0.15 lb/MMBtu on a 30-day rolling average basis, achievable 

through use of LNB/SOFA at SN-01 and SN-02. Compliance will be demonstrated using data from 

the existing CEMS. This determination is consistent with the BART determinations approved by 

EPA in Oklahoma, including the determinations for OG&E Seminole Units 1, 2, and 3 that 

combustion controls achieving 30-day rolling average NOX levels of 0.203 lb/MMBtu, 0.212

lb/MMBtu, and 0.164 lb/MMBtu, respectively, constitute BART and the determination for OG&E 

Sooner Units 1 and 2, OG&E Muskogee Unit 4, and AEP/PSO Northeastern Units 3 and 4 that 

combustion controls achieving a 30-day rolling average NOX level of 0.15 lb/MMBtu constitute 

BART.

6.7 PROPOSED BART FOR NOX FOR SN-05

Since baseline visibility modeling showed that there is no opportunity for visibility improvement 

attributable to SN-05 – because not a single day greater than 0.5 ∆dv is associated with SN-05 – it is 

not possible to install control equipment to improve visibility. Therefore, no controls is the NOX

BART determination for SN-05. This conclusion is consistent with EPA’s determinations in other 

states with similar auxiliary boilers.

7. PM10 BART EVALUATION

EPA’s Approval and Promulgation of Implementation Plans, published March 12, 2012, determined 

that the currently installed ESP is BART for PM10 for SN-01 and SN-02. 

The federally enforceable operating air permit states the PM emissions from the two units are 

controlled with ESPs and requires that the two units comply with a PM emission standard of 

0.10 lb/MMBtu. Since we have found that the visibility impact of the source due to PM 

emissions alone is so minimal such that the installation of any additional PM controls on the 

units would likely achieve very low emissions reductions, have minimal visibility benefits, 

and not be cost-effective, we are proposing to approve ADEQ’s determination that PM 

BART for both the bituminous and subbituminous coal firing scenarios is the existing PM 

emission limit for Units 1 and 2.42

As such, no further PM10 analysis has been conducted. 

Section 4 of this report summarized the baseline visibility impairment attributable to SN-01, SN-02 

and SN-05. Table 4-4 demonstrates that SN-05 does not contribute to a single day of visibility 

impairment greater than 0.5 Δdv. Therefore, no controls will be considered BART for SN-05. This 

conclusion is consistent with EPA’s determinations in other states with similar auxiliary boilers.

1: The costing method is modeled after the cost method summarized in Section 5.2 of the EPA Control Cost Manual (Post-Combustion Controls, Chapter 1 - Wet 

Scrubbers for Acid Gas, Table 1.3). Costs for AFUDC and capital suspense have been accounted for and added to the TCI calculated using the Cost Control Manual.

5: The direct costs include the fixed O&M from the S&L 2011 conceptual costs (operating labor, operating materials, and maintenance materials) plus variable O&M 

from the S&L 2011 conceptual costs (aux power, bags, cages, lime, limestone, and water)

2: The total equipment cost is the sum of the equipment and material costs from the November 30, 2012 Sargent & Lundy conceptual cost estimate.

4: CRF = [ I x (1+i)^a]/[(1+i)^a - 1], where I = interest rate, a = equipment life

3. Allowance for Funds Used During Construction (AFUDC) represents the costs of funds used for the capital project (i.e. debt and equity). For the purposes of this 

analysis, AFUDC has been assumed to be approximately the same for wet scrubbing as for semi-dry scrubbing.

CALMET MODELING PROTOCOL

As stated in Section 3.1, the meteorological data used in the analyses presented in this report was 

originally developed in 2007 and was first used in a BART determination for Oklahoma Gas & 

Electric. Because the development of a set of CALMET/CALPUFF meteorological data is so 

intensive, this same dataset has been used numerous times since 2007 for various other BART 

projects in EPA Region 6. The protocol that accompanied the original development has followed the 

dataset in each case and is doing so here again.

CALMET Processing Protocol 083701.0004

1. INTRODUCTION

Oklahoma Gas & Electric (OG&E) owns and operates three electric generating stations near

Muskogee, Oklahoma (Muskogee Generating Station), Seminole, Oklahoma (Seminole Generating 

Station), and Stillwater, Oklahoma (Sooner Generating Station). These generating stations are

considered eligible to be regulated under the U.S. Environmental Protection Agency’s (EPA) Best 

Available Retrofit Technology (BART) provisions of the Regional Haze Rule. This protocol 

describes the proposed methodology for conducting the CALMET data processing for the refined 

CALPUFF BART modeling analysis for OG&E’s Muskogee, Seminole, and Sooner Generating 

Stations. A detailed CALPUFF BART modeling protocol will be submitted in the near future and 

will include a discussion of the CALPUFF parameters as well as the post processing methodologies 

to be used in the refined modeling analysis for each station.

1.1 BEST AVAILABLE RETROFIT TECHNOLOGY RULE BACKGROUND

On July 1, 1999, the U.S. Environmental EPA published the final Regional Haze Rule (RHR). The 

objective of the RHR is to improve visibility in 156 specific areas across with United States, known 

as Class I areas. The Clean Air Act defines Class I areas as certain national parks (over 6000 acres), 

wilderness areas (over 5000 acres), national memorial parks (over 5000 acres), and international 

parks that were in existence on August 7, 1977.

On July 6, 2005, the EPA published amendments to its 1999 RHR, often called the BART rule, which 

included guidance for making source-specific Best Available Retrofit Technology (BART) 

determinations. The BART rule defines BART-eligible sources as sources that meet the following 

criteria: 

(1) Have potential emissions of at least 250 tons per year of a visibility-impairing pollutant,

(2) Began operation between August 7, 1962 and August 7, 1977, and

(3) Are listed as one of the 26 listed source categories in the guidance.

A BART-eligible source is not automatically subject to BART. Rather, BART-eligible sources are 

subject-to-BART if the sources are “reasonably anticipated to cause or contribute to visibility 

impairment in any federal mandatory Class I area.” EPA has determined that sources are reasonably 

anticipated to cause or contribute to visibility impairment if the visibility impacts from a source are 

greater than 0.5 deciviews (dv) when compared against a natural background.

Air quality modeling is the tool that is used to determine a source’s visibility impacts. States have the 

authority to exempt certain BART-eligible sources from installing BART controls if the results of the 

dispersion modeling demonstrate that the source cannot reasonably be anticipated to cause or 

contribute to visibility impairment in a Class I area. Further, states also have the authority to define 

the modeling procedures for conducting modeling related to making BART determinations.

CALMET Processing Protocol 083701.0004

1.2 OBJECTIVE

The objective of this document is to provide a protocol summarizing the modeling methods and 

procedures that will be followed to conduct the CALMET data processing necessary to complete a

refined CALPUFF modeling analysis for the OG&E generating stations discussed above. The 

modeling methods and procedures contained in this protocol and the CALPUFF protocol yet to be 

submitted will be used to determine appropriate controls for OG&E’s BART-eligible sources that can 

reasonably be anticipated to reduce the sources’ effects on or contribution to visibility impairment in 

the surrounding Class I areas. It is OG&E’s intent to determine a combination of emissions controls 

that will reduce the impact of each generating station to a degree that the 98th percentile of the 

visibility impact predicted by the model due to all the BART eligible sources at each station 

collectively is below EPA’s recommended visibility contribution threshold of 0.5 dv.

1.3 LOCATION OF SOURCES AND RELEVANT CLASS I AREAS

The sources listed in Table 1-1 are the sources that have been identified by OG&E as sources that 

meet the three criteria for BART-eligible sources.

As required in CENRAP’s BART Modeling Guidelines, Class I areas within 300 km of each station 

will be included in each analysis. The following table summarizes the distances of the four closest 

Class I areas to each station. As seen from this summary, some Class I areas are more than 300 km 

from the certain stations. However, in order to demonstrate that each station will not have an adverse 

effect on the visibility at any of the four nearest Class I areas, OG&E has opted to include those Class 

I areas more than 300 km away in this analysis. Note that the distances listed in the table below are 

the distances between the stations and the closest border of the Class I areas.

2. CALPUFF MODEL SYSTEM

The main components of the CALPUFF modeling system are CALMET, CALPUFF, and CALPOST. 

CALMET is the meteorological model that generates hourly three-dimensional meteorological fields 

such as wind and temperature. CALPUFF simulates the non-steady state transport, dispersion, and 

chemical transformation of air pollutants emitted from a source in “puffs”. CALPUFF calculates 

hourly concentrations of visibility affecting pollutants at each specified receptor in a modeling 

domain. CALPOST is the post-processor for CALPUFF that computes visibility impacts from a 

source based on the visibility affecting pollutant concentrations that were output by CALPUFF.

2.1 MODEL VERSIONS

The versions of the CALPUFF modeling system programs that are proposed for conducting OG&E’s 

BART modeling are listed in Table 2-1. A detailed refined CALPUFF BART modeling protocol will 

be submitted in the near future.

2.2 MODELING DOMAIN

The CALPUFF modeling system utilizes three modeling grids: the meteorological grid, the 

computational grid, and the sampling grid. The meteorological grid is the system of grid points at 

which meteorological fields are developed with CALMET. The computational grid determines the 

computational area for a CALPUFF run. Puffs are advected and tracked only while within the 

computational grid. The meteorological grid is defined so that it covers the areas of concern and 

gives enough marginal buffer area for puff transport and dispersion. A plot of the proposed 

meteorological modeling domain with respect to the Class I areas being modeled is also provided in 
OG&E 2-2 Trinity Consultants

CALMET Processing Protocol 083701.0004

Figure 2-1. The computational domain will be set to extend at least 50 km in all directions beyond 

the Muskogee, Seminole, and Sooner Generating Stations and the Class I areas of interest. Note that 

the map projection for the modeling domain will be Lambert Conformal Conic (LCC) and the datum 

will be the World Geodetic System 84 (WGS-84). The reference point for the modeling domain is

Latitude 40oN, Longitude 97oW. The southwest corner will be set to -951.547 km LCC, -1646.637 

km LCC corresponding to Latitude 24.813 oN and Longitude 87.778oW. The meteorological grid 

spacing will be 4 km, resulting in 462 grid points in the X direction and 376 grid points in the Y 

direction.

3. CALMET

The EPA Approved Version of the CALMET meteorological processor will be used to generate the 

meteorological data for CALPUFF. CALMET is the meteorological processor that compiles 

meteorological data from raw observations of surface and upper air conditions, precipitation 

measurements, mesoscale model output, and geophysical parameters into a single hourly, gridded 

data set for input into CALPUFF. CALMET will be used to assimilate data for 2001- 2003 using 

National Weather Service (NWS) surface station observations, upper air station observations, 

precipitation station observations, buoy station observations (for overwater areas), and mesoscale 

model output to develop the meteorological field. 

3.1 GEOPHYSICAL DATA

CALMET requires geophysical data to characterize the terrain and land use parameters that 

potentially affect dispersion. Terrain features affect flows and create turbulence in the atmosphere 

and are potentially subjected to higher concentrations of elevated puffs. Different land uses exhibit 

variable characteristics such as surface roughness, albedo, Bowen ratio, and leaf-area index that also 

effect turbulence and dispersion. 

3.1.1 TERRAIN DATA

Terrain data will be obtained from the United States Geological Survey (USGS) in 

1-degree (1:250,000 scale or approximately 90 meter resolution) digital format. The

USGS terrain data will then be processed by the TERREL program to generate grid-cell 

elevation averages across the modeling domain. A plot of the land elevations based on the 

USGS data for the modeling domain is provided in Figure 3-1.

3.1.2 LAND USE DATA

The land use land cover (LULC) data from the USGS North American land cover 

characteristics data base in the Lambert Azimuthal equal area map projection will be used 

in order to determine the land use within the modeling domain. The LULC data will be 

processed by the CTGPROC program which will generate land use for each grid cell 

across the modeling domain. A plot of the land use based on the USGS data for the 

modeling domain is provided in Figure 3-2.

The terrain data files output by the TERELL program and the LULC files output by the 

CTGPROC program will be uploaded into the MAKEGEO program to create a 

geophysical data file that will be input into CALMET. 

3.2 METEOROLOGICAL DATA 

CALMET will be used to assimilate data for 2001, 2002, and 2003 using mesoscale model output and 

National Weather Service (NWS) surface station observations, upper air station observations,

precipitation station observations, and National Oceanic and Atmosphere Administrations (NOAA) 

buoy station observations to develop the meteorological field. 

3.2.1 MESOSCALE MODEL METEOROLOGICAL DATA

Hourly mesoscale data will also be used as the initial guess field in developing the 

CALMET meteorological data. It is OG&E’s intent to use the following 5th generation 

mesoscale model meteorological data sets (or MM5 data) in the analysis:

 2001 MM5 data at 12 km resolution generated by the U.S. EPA 

 2002 MM5 data at 36 km resolution generated by the Iowa DNR

 2003 MM5 data set at 36 km resolution generated by the Midwest RPO

The specific MM5 data that will be used are subsets of the data listed above. As the 

contractor to CENRAP for developing the meteorological data sets for the BART 

modeling, Alpine Geophysics extracted three subsets of MM5 data for each year from 

2001 to 2003 from the data sets listed above using the CALMM5 extraction program. The 

three subsets covered the northern, central, and southern portions of CENRAP. TXI is 

proposing to use the southern set of the extracted MM5 data. 

The 2001 southern subset of the extracted MM5 data includes 30 files that are broken into 

10 to 11 day increments (3 files per month). The 2002 and 2003 southern subsets of 

extracted MM5 data include 12 files each of which are broken into 30 to 31 day increment

files (1 file per month). Note that the 2001 to 2003 MM5 data extracted by Alpine

Geophysics will not be able to be used directly in the modeling analysis. To run the Alpine 

Geophysics extracted MM data in the EPA approved CALMET program, each of the MM5 

files will need to be adjusted by appending an additional six (6) hours, at a minimum, to 

the end of each file to account for the shift in time zones from the Greenwich Mean Time 

(GMT) prepared Alpine Geophysics data to Time Zone 6 for this analysis. No change to 

the data will occur. 

The time periods covered by the data in each of the MM5 files extracted by Alpine 

Geophysics include a specific number of calendar days, where the data starts at Hour 0 in 

GMT for the first calendar day and ends at Hour 23 in GMT on the last calendar day. In 

order to run CALMET in the local standard time (LST), which is necessary since the 

surface meteorological observations are recorded in LST, there must be hours of MM5 data 

referenced in a CALMET run that match the LST observation hours. Since the LST hours 

in Central Standard Time (CST) are 6 hours behind GMT, it is necessary to adjust the data 

in each MM5 file so that the time periods covered in the files match CST. 

Based on the above discussion, the Alpine Geophysics MM5 data will not be used directly. 

Instead the data files will be modified to add 8 additional hours of data to the end of each

file from the beginning of the subsequent file. CALMET will then be run using the 

appended MM5 data to generate a contiguous set of CALMET output files. The converted 

MM5 data files occupy approximately 1.2 terabytes (TB) of hard drive space.

3.2.2 SURFACE METEOROLOGICAL DATA

Parameters affecting turbulent dispersion that are observed hourly at surface stations 

include wind speed and direction, temperature, cloud cover and ceiling, relative humidity, 

and precipitation type. It is OG&E’s intent to use the surface stations listed in Table A-1 

of Appendix A. The locations of the surface stations with respect to the modeling domain 

are shown in Figure 3-3. The stations were selected from the available data inventory to 

optimize spatial coverage and representation of the domain. Data from the stations will be 

processed for use in CALMET using EPA’s SMERGE program.

CALMET Processing Protocol 083701.0004

FIGURE 3-3. PLOT OF SURFACE STATION LOCATIONS

3.2.3 UPPER AIR METEOROLOGICAL DATA

Observations of meteorological conditions in the upper atmosphere provide a profile of 

turbulence from the surface through the depth of the boundary layer in which dispersion 

occurs. Upper air data are collected by balloons launched simultaneously across the 

observation network at 0000 Greenwich Mean Time (GMT) (6 o’clock PM in Oklahoma) 

and 1200 GMT (6 o’clock AM in Oklahoma). Sensors observe pressure, wind speed and 

direction, and temperature (among other parameters) as the balloon rises through the 

atmosphere. The upper air observation network is less dense than surface observation 

points since upper air conditions vary less and are generally not as affected by local effects 

(e.g., terrain or water bodies). The upper air stations that are proposed for this analysis are 

listed in Table A-2 of Appendix A. The locations of the upper air stations with respect to 

the modeling domain are shown in Figure 3-4. These stations were selected from the 

available data inventory to optimize spatial coverage and representation of the domain. 

Data from the stations will be processed for use in CALMET using EPA’s READ62 

program.

3.2.4 PRECIPITATION METEOROLOGICAL DATA

The effects of chemical transformation and deposition processes on ambient pollutant 

concentrations will be considered in this analysis. Therefore, it is necessary to include 

observations of precipitation in the CALMET analysis. The precipitation stations that are 

proposed for this analysis are listed in Table A-3 of Appendix A. The locations of the 

precipitation stations with respect to the modeling domain are shown in Figure 3-5. These 

stations were selected from the available data inventory to optimize spatial coverage and 

representation of the domain. Data from the stations will be processed for use in 

CALMET using EPA’s PMERGE program.

The effects of land/sea breeze on ambient pollutant concentrations will be considered in 

this analysis. Therefore, it is necessary to include observations of buoy stations in the 

CALMET analysis. The buoy stations that are proposed for this analysis are listed in Table 

A-4 of Appendix A. The locations of the buoy stations with respect to the modeling 

domain are shown in Figure 3-6. These stations were selected from the available data 

inventory to optimize spatial coverage and representation of the domain along the 

coastline. Data from the stations will be prepared by filling missing hour records with the 

CALMET missing parameter value (9999). No adjustments to the data will occur.

3.3 CALMET CONTROL PARAMETERS

Appendix B provides a sample CALMET input file used in OG&E’s modeling analysis. A few 

details of the CALMET model setup for sensitive parameters are also discussed below. 

3.3.1 VERTICAL METEOROLOGICAL PROFILE

The height of the top vertical layer will be set to 3,500 meters. This height corresponds to 

the top sounding pressure level for which upper air observation data will be relied upon. 

The vertical dimension of the domain will be divided into 12 layers with the maximum 

elevations for each layer shown in Table 3-1. The vertical dimensions are weighted 

towards the surface to resolve the mixing layer while using a somewhat coarser resolution 

for the layers aloft.

CALMET allows for a bias value to be applied to each of the vertical layers. The bias 

settings for each vertical layer determine the relative weight given to the vertically 

extrapolated surface and upper air wind and temperature observations. The initial guess 

fields are computed with an inverse distance weighting (1/r

2

) of the surface and upper air 

data. The initial guess fields may be modified by a layer dependent bias factor. Values for 

the bias factor may range from -1 to +1. A bias of -1 eliminates upper-air observations in

the 1/r2interpolations used to initialize the vertical wind fields. Conversely, a bias of +1 

eliminates the surface observations in the interpolations for this layer. Normally, bias is set 

to zero (0) for each vertical layer, such that the upper air and surface observations are given 

equal weight in the 1/r2interpolations. The biases for each layer of the proposed modeling 

domain will be set to zero.

CALMET allows for vertical extrapolation of surface wind observations to layers aloft to 

be skipped if the surface station is close to the upper air station. Alternatively, CALMET 

allows data from all surface stations to be extrapolated. The CALMET parameter that 

controls this setting is IEXTRP. Setting IEXTRP to a value less than zero (0) means that 

layer 1 data from upper air soundings is ignored in any vertical extrapolations. IEXTRP 

will be set to -4 for this analysis (i.e., the similarity theory is used to extrapolate the surface 

winds into the layers aloft, which provides more information on observed local effects to 

the upper layers).

3.3.2 INFLUENCES OF OBSERVATIONS

Step 1 wind fields will be based on an initial guess using MM5 data and refined to reflect 

terrain affects. Step 2 wind fields will adjust the Step 1 wind field by incorporating the 

influence of local observations. An inverse distance method is used to determine the 

influence of observations to the Step 1 wind field. RMAX1 and RMAX2 define the radius 

of influence for data from surface stations to land in the surface layer and data from upper 

air stations to land in the layers aloft. In general, RMAX1 and RMAX2 are used to 

exclude observations from being inappropriately included in the development of the Step 2

wind field if the distance from an observation station to a grid point exceeds the maximum 

radius of influence. 

If the distance from an observation station to a grid point is less than the value set for 

RMAX, the observation data will be used in the development of the Step 2 wind field. R1 

represents the distance from a surface observation station at which the surface observation 

and the Step 1 wind field are weighted equally. R2 represents the comparable distance for 

winds aloft. R1 and R2 are used to weight the observation data with respect to the MM5 

data that was used to generate the Step 1 wind field. Large values for R1 and R2 give 

more weight to the observations, where as small values give more weight to the MM5 data. 

In this BART modeling analysis, RMAX 1 will be set to 20 km, and R1 will be set to 10 

km. This will limit the influence of the surface observation data from all surface stations to 

20 km from each station, and will equally weight the MM5 and observation data at 10 km. 

RMAX2 will be set to 50 km, and R2 will be set to 25 km. This will limit the influence of 

the upper air observation data from all surface stations to 50 km from each station, and will 

equally weight the MM5 and observation data at 25 km. These settings of radius of 

influence will allow for adequate weighting of the MM5 data and the observation data 

across the modeling domain due to the vast domain to be modeled. RAMX 3 will be set to 

500 km.

1. INTRODUCTION 

1.1. OBJECTIVE 

The intent of this study is to provide Gill Elrod Ragon Owen & Sherman, P.A. with a technology 

evaluation and cost estimates for available methods of NOx control at two Entergy stations including: 

White Bluff – Units 1 & 2, the White Bluff Auxiliary Boiler, and Lake Catherine – Unit 4. The 

information developed in this study will be used to create a BART analysis, for compliance with 

Arkansas DEQ regulations. 

1.2. UNIT DESCRIPTIONS 

1.2.1. White Bluff - Units 1 & 2 

White Bluff - Units 1 & 2 are Alstom-designed, tangentially-fired, pulverized-coal fueled units, rated at 

815 MWnet and 844 MWnet respectively. Powder River Basin coal is the primary fuel source for Units 1 

& 2. Currently, the units have no NOx controls installed. 

1.2.2. White Bluff Auxiliary Boiler 

The White Bluff Auxiliary boiler is a small industrial boiler capable of producing 140,000 lb/hr of steam, 

used for startup of the White Bluff coal units. The auxiliary boiler combusts No. 2 Diesel Oil, and does 

not have any existing NOx controls. 

1.2.3. Lake Catherine - Unit 4 

Lake Catherine - Unit 4 is an Alstom-designed, tangentially-fired, natural gas fueled unit, capable of 

generating 558 MWnet. The unit was originally designed as a dual-fuel unit, able to use natural gas or 

No. 2 Fuel Oil as fuel. This evaluation will be for natural gas firing only. If No. 2 Fuel Oil is to be 

combusted in the future, a separate BART analysis will be submitted. The unit currently has no NOx 

controls.

1.3. ESTIMATE METHODOLOGY 

1.3.1. Capital Cost Estimates 

S&L’s capital cost estimates for retrofit NOx control technologies for White Bluff Units 1&2, White 

Bluff Auxiliary Boiler and Lake Catherine – Unit 4 encompass the equipment, material, labor, and all 

other required direct costs. The underlying assumption is that the project will be implemented on a 

multiple-contracting basis. The capital cost estimates provided herein are “total plant cost,” and include 

the following: 

 Equipment and material 

 Installation labor 

 Indirect field costs and BOP engineering 

 Contingency (percentage varies with project size) 

 Erection contractor profit (at 10% of material and labor) 

 General and administration (at 5% of material and labor) 

 Freight on material (at 5% of material) 

 Freight on equipment (included with equipment costs) 

 Sales/use tax (not included) 

 Startup and commissioning (at 1% of construction cost) 

 Spare parts (included with equipment costs) 

 Consumables (0.5% of material and labor) 

Owner’s engineering and other Owner’s costs were not included. Engineering, Procurement & Project 

Services and Contingency varied depending on the size of the project. License fees and royalties are not 

expected for the proposed control strategies. The Basis of Estimate and capital costs are summarized in 

Appendix A. 

Capital cost estimates were calculated in one of three ways. In some cases, vendors were contacted to 

provide budgetary estimates for equipment and labor. These vendor’s costs were used to create Total 

Installed Cost Estimates. In situations where Sargent & Lundy had performed cost estimates for these 

units previously, the existing cost estimates were updated to reflect current equipment, labor, and 

currency values. Remaining cost estimates were developed from similar projects that Sargent & Lundy 

has completed and adjusted for unit size.

1.3.2. Operating and Maintenance Cost Estimates 

Operating and Maintenance Costs for White Bluff - Units 1 & 2 and Lake Catherine – Unit 4 were 

developed from similar projects Sargent & Lundy has completed. Costs were applied to the units on a 

$/kW basis, and assuming a 10% capacity factor for Lake Catherine – Unit 4, and 76% for White Bluff—

Units 1 & 2. Operating and Maintenance Costs include the following costs: 

 Fixed Operating and Maintenance 

 Variable Operating and Maintenance 

 Fuel Impact Costs 

For the White Bluff Auxiliary boiler, costs were developed using Office of Air Quality Planning and 

Standards (OAQPS) calculations, assuming a 10% capacity factor. 

1.4. DESIGN TARGET vs. COMPLIANCE NOX EMISSION RATES 

NOx control systems retrofit onto existing coal or gas-fired boilers are typically designed to achieve 

varying levels of NOx removal efficiencies from 10%-94%, depending on the control technologies 

selected. Controlled NOx emissions fluctuate during normal boiler operation in response to a number of 

design/operating parameters including, but not necessarily limited to: inlet NOx concentrations, boiler 

load, load changes, particulate matter loading, flue gas temperatures, flue gas velocities and mixing, 

catalyst volume and surface area, NH3:NOx stoichiometric ratio, catalyst age and activity, and the 

quantity of ammonia slip deemed to be acceptable. 

The “design target” NOx emission rate is the rate that a NOx control technology vendor would be willing 

to guarantee. Based on engineering judgment, and taking into consideration emissions data from existing 

coal- and gas-fired sources, a compliance margin above the design target is recommended for high 

removal efficiency/low emission rate technologies (such as SCR) to establish an enforceable permit limit 

based on long-term (e.g., annual average) emissions. Additional compliance margin would be required to 

establish enforceable permit limits based on shorter-term averaging times. For example, S&L 

recommends a compliance margin of 0.02 to 0.03 lb/MMBtu for coal units and 0.01 to 0.02 lb/MMBtu 

for gas units above the design target emission rate for permit limits based on a 30-day rolling average for 

control strategies including SCR. The NOx control technology emission rates for strategies including 

SCR in this report have been adjusted to include margin for compliance. The permit level NOx emission

rates for SCR are higher by 0.02 to 0.03 lb/MMBtu for coal units and 0.01 to 0.02 lb/MMBtu for gas 

units. 

2. WHITE BLUFF - UNITS 1 & 2 

2.1. FUEL SWITCHING OPTIONS 

2.1.1. Natural Gas 

For White Bluff Units 1 & 2, fuel switching is not a feasible option. Typically, units could be switched 

from coal to natural gas or propane for NOx reductions. The nearest natural gas pipeline to the White 

Bluff facility is approximately 20 miles away. Construction of a pipeline is currently estimated at $2M 

per mile resulting in a cost of $40M to bring natural gas to the site, not including the additional upgrades 

the boiler would require to burn natural gas instead of coal. 

2.1.2. Propane 

White Bluff – Units 1 & 2 are each over 800 MWnet. Units of this size require more heat input than can 

practically be achieved with a propane delivery and storage system. Since a propane pipeline is not 

available, fuel switching to propane is not a feasible option. 

2.2. COMBUSTION CONTROLS 

2.2.1. Low NOx Burners and Over-Fire Air 

Low NOx burners (LNB) limit NOx formation by controlling both the stoichiometric and temperature 

profiles of the combustion flame in each burner flame envelope. Control is achieved with design features 

that regulate the aerodynamic distribution and mixing of the fuel and air, yielding reduced oxygen (O2) in 

the primary combustion zone, reduced flame temperature, and reduced residence time at peak combustion 

temperatures. The combination of these techniques produces lower NOx emissions during the combustion 

process. 

OFA involves injecting combustion air downstream of the fuel-rich primary combustion zone by using 

over-fire air or side-fired air ports. The fuel-rich mixture that is fed to the burners reduces the flame

temperature and oxygen concentration thus reducing the formation of thermal NOx. Generally, OFA is 

more effective when used with low nitrogen content fuels such as natural gas and propane, since OFA is 

more effective in controlling thermal NOx rather than fuel NOx. 

LNB + OFA is a technically feasible retrofit solution for White Bluff - Units 1 & 2. The combination of 

LNB + OFA is capable of achieving a NOx emission rate of 0.15 lb/MMBtu. From Unit 1’s baseline 

emissions of 0.33 lb/MMBtu, this is approximately 54.5% NOx removal efficiency. A removal efficiency 

of 61.5% can be expected for Unit 2, with a baseline NOx of 0.39 lb/MMBtu. 

2.2.2. Flue Gas Recirculation (FGR) 

NOx reduction efficiency data for coal-fired units with FGR are limited. The amount of NOx reduction 

achievable with FGR depends primarily on the fuel nitrogen content and amount of FGR used. Generally, 

FGR is more effective when used with low nitrogen content fuels such as natural gas and propane, since 

FGR is more effective in controlling thermal NOx rather than fuel NOx. Industry experience with FGR on 

coal-fired units for steam temperature control has shown very high maintenance on the gas recirculation 

fans due to erosion and corrosion. Many of the units with FGR for steam temperature control have 

removed the recirculation fans from service. The NOx control achievable on tangentially fired units like 

White Bluff – Units 1&2 with LNB+OFA has been comparable to that of FGR at lower capital and O&M 

cost. Currently, FGR technology is not offered by OEMs for coal-fired units. For these reasons, FGR is 

not a feasible technology for the White Bluff coal-fired units. 

2.2.3. Neural Network 

Neural Network (NN) systems are on-line enhancements to digital control systems (DCS) and plant 

information systems that improve boiler performance parameters such as heat rate, NOx emissions, and 

CO levels. The Neural Network model is based on historical data and parametric test data. The software 

applies an optimizing procedure to identify the best set points for the boiler, which are implemented 

without operator intervention (closed loop), or, at the plant’s discretion, conveyed to the plant operators 

for implementation (open loop). 

A Neural Network system is a technically feasible retrofit option for the White Bluff units. A NN is 

already installed for monitoring and controlling heat rate at White Bluff – Units 1&2. The reprogrammed

NN would be optimized first for minimizing NOx emissions and second for heat rate. It is possible that 

heat rate may increase as a result. Based on information available from vendors, it is expected that Neural 

Network technology on a coal-fired boiler can maintain the guaranteed performance of low NOx burners 

and potentially can achieve approximately 10% NOx reduction over a period of years, resulting in NOx 

emission rates of 0.30 lb/MMBtu, at max load for Unit 1, and of 0.35 lb/MMBtu for Unit 2. The cost for 

modifying the existing NNs at White Bluff is estimated to be approximately $250,000 per unit. 

2.3. POST COMBUSTION CONTROLS 

2.3.1. Selective Non-Catalytic Reduction 

Selective non-catalytic reduction (SNCR) involves the direct injection of ammonia (NH3) or urea 

(CO(NH2)2) into the furnace at high flue gas temperatures (approximately 1600 oF – 2000 oF). The 

ammonia or urea reacts with NOx in the flue gas to produce N2 and water as shown in the following 

equations: 

(CO(NH2)2) + 2NO + 1⁄2O2 → 2H2O + CO2 + 2N2

2NH3 + 2NO + 1⁄2O2 → 2N2 + 3H2O 

Flue gas temperature at the point of reactant injection can greatly affect NOx removal efficiencies and the 

quantity of NH3 or urea that will pass through the furnace unreacted (referred to as NH3 slip). In general, 

SNCR reactions are effective at a temperature range of 1600 oF – 2000 oF. At temperatures below the 

desired operating range, the NOx reduction reactions diminish and unreacted NH3 emissions increase. 

Above the desired temperature range, NH3 is oxidized to NOx resulting in low NOx reduction 

efficiencies. 

Mixing of the reactant and flue gas within the reaction zone is also an important factor to SNCR 

performance. In large boilers, the physical distance over which reagent must be dispersed increases, and 

the surface area/volume ratio of the convective pass decreases. Both of these factors make it difficult to 

achieve good mixing of reagent and flue gas, delivery of reagent in the proper temperature window, and 

sufficient residence time of the reactant and flue gas in that temperature window.

Page No. 7 

The temperatures and residence times required for an SNCR system make it a feasible option for NOx 

reduction for White Bluff - Units 1 & 2. Based on vendor input, a unit with no additional controls and a 

baseline NOx of 0.33 lb/MMBtu could see a 26.5% NOx reduction, for an outlet rate of 0.24 lb/MMBtu 

on Unit 1. For Unit 2, with a baseline NOx of 0.39 lb/MMBtu could see a 26.5% reduction to an outlet 

rate of 0.29 lb/MMBtu. 

SNCR systems can also be installed in conjunction with LNB + OFA controls. On these coupled systems, 

the starting NOx of approximately 0.15 lb/MMBtu can be reduced to 0.13 lb/MMBtu, for a total reduction 

(LNB + OFA + SNCR) of around 61% for Unit 1 and 67% for Unit 2. In addition to the SNCR 

equipment, the process requires additional demineralized water at a rate of 170 gpm. An additional water 

treatment system capable of providing the required flows is included in the capital cost. The cost of the 

SNCR equipment for the combination technology would be approximately 10% lower based on the lower 

starting NOx rate with LNB/OFA. 

2.3.2. Selective Catalytic Reduction 

Selective Catalytic Reduction (SCR) involves injecting ammonia into boiler flue gas in the presence of a 

catalyst to reduce NOx to N2 and water. The overall SCR reactions are: 

4NH3 + 4NO + O2 → 4N2 + 6H2O 

8NH3 + 4NO2 + 2O2 → 6N2 + 12H2O 

The optimal temperature range depends on the type of catalyst used, but is typically between 560 °F and 

800 °F to maximize NOx reduction efficiency and minimize ammonium sulfate formation. Below this 

range, ammonium sulfate is formed resulting in catalyst deactivation. Above the optimum temperature, 

the catalyst will sinter and thus deactivate rapidly. Another factor affecting SCR performance is the 

condition of the catalyst material. As the catalyst degrades over time or is damaged, NOx removal 

decreases which is typically compensated by increased ammonia slip. 

SCR has been installed on many large coal-fired and some gas-fired boilers and is considered a feasible 

technology. Because of the expense of the reagent, SCR systems are usually installed on units with 

existing LNB + OFA systems, or the upgrades are done simultaneously. At White Bluff, an 

SCR+LNB/OFA system is capable of removing approximately 90% of NOx emissions on a continuous

long-term basis. With a starting NOx of 0.33 lb/MMBtu (Unit 1) to 0.39 lb/MMBtu (Unit 2), an SCR can 

be expected to achieve permitted emissions compliance at 0.055 lb/MMBtu. 

2.4. CAPITAL COSTS 

Capital costs for the technically feasible control options for the White Bluff coal units are listed in Table 

2.1. The cost of SCR on White Bluff – Unit 1 is higher than for White Bluff – Unit 2 because the 

ductwork arrangement is different and there is more total ductwork, support steel, and foundations for 

Unit 1.

3. WHITE BLUFF AUXILIARY BOILER 

3.1. FUEL SWITCHING 

The White Bluff auxiliary boiler is a B&W, single burner boiler, firing No. 2 diesel oil, rated at 140,000 

lb/hr of steam. Fuel switching to natural gas or propane is not practical because the nearest natural gas 

pipeline is 20 miles from the site. The costs to convert the White Bluff aux boiler to either natural gas or 

propane would not be justified based on the low capacity factor. 

3.2. COMBUSTION CONTROLS 

3.2.1. Low NOx Burners + Over-Fire Air 

For an auxiliary boiler such as the one at White Bluff, NOx reduction can be achieved with a combination 

of technologies. LNB + OFA for aux boilers achieve NOx reduction under the same principles as a coal 

boiler. By modifying temperatures and fuel-rich areas, less NOx is generated. LNB + OFA are feasible 

technologies for auxiliary boilers, and vendor data indicates that the White Bluff Aux Boiler could 

achieve 35% reduction with LNB + OFA, for a final emission of 0.11 lb/MMBtu. The baseline NOx 

emissions from the White Bluff aux boiler are calculated using US EPA’s AP-42 emissions factors. 

3.2.2. Flue Gas Recirculation 

NOx reduction efficiency data for oil-fired units with FGR are limited. The amount of NOx reduction 

achievable with FGR depends primarily on the fuel nitrogen content and amount of FGR used. Generally, 

FGR is more effective when used with low nitrogen content fuels such as natural gas and propane, since 

FGR is more effective in controlling thermal NOx rather than fuel NOx. FGR is a feasible technology for 

the White Bluff auxiliary boiler. With a recirculation of 15% of the flue gas, the unit could expect to see 

13% NOx removal, for an outlet of 0.149 lb/MMBtu. 

3.2.3. Low NOx Burners + Over-fire Air + Flue Gas Recirculation 

These three technologies are often installed simultaneously for greater NOx reduction. A vendor has 

proposed that for the White Bluff aux boiler, a combination of LNB + OFA + FGR will reduce the NOx

from 0.171 lb/MMBtu to 0.100 lb/MMBtu when burning No. 2 Fuel Oil. This reduction of 42% will 

come from a new LNB and OFA system and the recirculation of 15% of the flue gas flow. 

3.2.4. Neural Network 

The White Bluff Auxiliary Boiler is not a candidate for a neural network (NN) because there are few 

controllable variables to be optimized. The aux boiler also uses a relatively new PLC control system. 

3.3. POST COMBUSTION CONTROLS 

3.3.1. Selective Non-Catalytic Reduction 

SNCR control has proven to be difficult to apply to industrial boilers because of the temperature and 

mixing requirements, especially industrial boilers that modulate or cycle frequently. In order to 

effectively reduce NOx emissions, the reactant (ammonia or urea) must be injected into the flue gas 

within a specific flue gas temperature window, and must remain within that temperature window for a 

sufficient residence time. In industrial boilers that cycle frequently, the location of the specific exhaust 

gas temperature window is constantly changing. Thus, SNCR has not been effective on industrial boilers 

that have high turndown capabilities and modulate or cycle frequently. Based on the temperature and 

residence time requirements associated with effective NOx reduction, the planned use of the auxiliary 

boiler, and the limited availability of SNCR control systems for industrial boilers, it has been determined 

that SNCR is not technically feasible for the White Bluff auxiliary boiler. 

3.3.2. Selective Catalytic Reduction 

SCR for NOx control on auxiliary boilers is not common, because of their cycling operation, and the use 

of fuel oil. SCRs have critical operating temperature ranges, which are difficult to achieve and maintain 

in short periods of time. Because of the sulfur content of diesel oil, the SCR catalyst can become 

poisoned, resulting in a lower NOx removal efficiency. With this lower efficiency and high cost, an SCR 

is not considered a feasible technology.

4. LAKE CATHERINE - UNIT 4 

4.1. FUEL SWITCHING 

Lake Catherine - Unit 4 already combusts natural gas, which has the lowest NOx formation of potential 

fuels. Because fuel switching would not result in a lower NOx emission rate, it is not a feasible option for 

NOx control. 

4.2. COMBUSTION CONTROLS 

4.2.1. Burners-Out-Of-Service 

Burners-Out-Of-Service (BOOS) allows operators to stop fuel flow to certain burners in the boiler 

(typically the top level of burners), while air flow is maintained. By removing fuel from the top row of 

burners, the combustion air becomes over-fire air and the production of thermal NOx is reduced. While 

the reduction of NOx can be significant, the tradeoff is a reduced generating capacity, if no further 

modifications to the firing system are made. BOOS is a feasible technology for Lake Catherine - Unit 4. 

Testing of BOOS at Lake Catherine by Entropy Technology & Environmental Consultants, Inc. (ETEC) 

with the top levels of burners out resulted in a maximum load of 405 MW, a 28% reduction in capacity, 

and NOx levels of 0.12 lb/MMBtu, a reduction of 55% from the baseline while using the existing burners. 

Recovery of the lost unit capacity is possible by increasing the fuel fired in the three levels of burners that 

remain in service. The burners remaining in service would have to increase fuel throughput by 25%. The 

natural gas piping to each burner may also have to be increased in size for the higher fuel flow rates. 

ETEC, Inc. has experience with several units similar in design to Lake Catherine – Unit 4 that have been 

able to achieve full capacity by increasing the original “high” burner header pressure (BHP) to increase 

fuel flow to the burners (See Appendix D). The increase in BHP from 42 to 50 psig at Lake Catherine – 

Unit 4 would increase fuel flow by 25% and the burners would be operated “fuel rich”, lowering NOx 

formation. Using this approach would reduce NOx emissions at a small capital cost. The costs for BOOS 

with recovery of full unit capacity were based on vendor cost information for a previous project adjusted 

on a $/kW basis to Lake Catherine – Unit 4 and escalated to 2012. The cost provided does not include 

any modifications to the boiler. A boiler OEM or consultant would need to evaluate the existing fuel 

piping, superheat and reheat attemperation sprays, tube metal temperatures and burner tilt positions for

the new operating conditions. The expected NOx reduction would range from 40% at low load to 50% at 

full load and NOx levels of 0.24 lb/MMBtu. 

4.2.2. Low NOx Burners + Over-Fire Air 

Low NOx Burners and Over-Fire Air for a gas-fired unit function similarly to coal-fired boilers, as 

discussed for White Bluff - Units 1 & 2. By controlling the temperature and stoichiometric profiles, the 

NOx produced as a result of thermal processes is reduced. 

LNB + OFA are commonly installed on gas-fired units of this size, and are a feasible retrofit technology 

for Lake Catherine - Unit 4. With the installation of LNB + OFA, Lake Catherine could expect a 60% 

reduction in NOx, from 0.4825 lb/MMBtu to 0.19 lb/MMBtu. 

4.2.3. Flue Gas Recirculation 

Flue Gas Recirculation (FGR) reduces NOx by recirculating flue gas to the furnace. This recirculated gas 

has lower oxygen content than ambient air usually used for combustion. Lower oxygen and lower flame 

temperatures reduces thermal NOx formation. FGR can be installed on a unit in two ways. Traditional 

FGR installations require a new recirculation fan. Induced FGR, or IFGR, installs ductwork from the air 

preheater outlet to the suction of the existing forced draft fan. IFGR does not require a separate fan, but 

due to FD fan capacity restrictions, IFGR is not available at higher loads, because the forced draft fans 

were not designed for the higher air and gas flow rate. 

FGR is technically feasible on Lake Catherine - Unit 4 and can result in reductions of 60%. For Unit 4, 

this would be equivalent to NOx emissions of 0.19 lb/MMBtu. 

4.2.4. Water Injection 

Water injection operates on similar principles to LNB + OFA and FGR. By injecting water into the 

furnace, the temperature of the flue gas is reduced, thereby reducing the amount of thermal NOx formed. 

Water injection is a feasible technology for Lake Catherine - Unit 4, and can reduce NOx emissions by 

9% at full load. Water injection is typically used as a trimming technology at high load. On Unit 4, the 

emissions would be lowered from the baseline of 0.4825 lb/MMBtu to 0.44 lb/MMBtu.

4.2.5. Neural Network 

Lake Catherine – Unit 4 could also install a neural network (NN) but for the low capacity factor and 

current lack of NOx CEMS, a NN would not be practical. Several of the other technologies would provide 

greater NOx reductions. 

4.3. POST COMBUSTION CONTROLS 

4.3.1. Selective Non-Catalytic Reduction 

Selective Non-Catalytic Reduction for gas-fired units operates under the same principles as SNCR for 

coal-fired units, with a few design changes. One of the keys of SNCR design is adequate chemical 

distribution at the right temperature for the reaction. Lake Catherine - Unit 4 has horizontal superheat 

platens, which requires multiple-nozzle lances to distribute the urea; the gas pattern does not provide 

adequate distribution. The reaction and temperature requirements are the same for gas-fired boilers as 

they are for coal-fired units. 

SNCR has been installed on boilers such as Lake Catherine 4 and is considered a feasible technology, 

although the residence time in the desired temperature zone is lower for a gas-fired unit and the 

temperature window moves as unit load changes. The unit could expect to see reductions in NOx from 

the baseline of 0.4825 lb/MMBtu to 0.29 lb/MMBtu, or approximately 40% reduction at full load. In 

addition to the SNCR equipment, the process requires additional demineralized water at a rate of 85 gpm. 

An additional water treatment system capable of providing the required flows is included in the capital 

cost. 

SNCR can be combined with LNB/OFA to achieve a combined NOx removal efficiency of 70% for an 

outlet emission of approximately 0.14 lb/MMBtu, 

4.3.2. Selective Catalytic Reduction 

Selective Catalytic Reduction units are similar for gas and coal-fired units. Ammonia or urea reagent 

reacts with NOx to form nitrogen and water, in the presence of a catalyst. Because gas boilers do not 

have particulate control or sulfur dioxide control, they typically have a shorter distance from the 

economizer outlet to the stack, which may result in long ductwork runs to and from the SCR.

SCR is a feasible technology for Lake Catherine - Unit 4. Combined with a LNB + OFA installation, 

which is typical of SCR installations, the unit could achieve a combined NOx removal efficiency of 94%, 

for a permitted outlet NOx of 0.03 lb/MMBtu at full load. This includes a margin for compliance as 

discussed in Section 1.4. Without the LNB + OFA installed, the SCR can also be designed to achieve 

90% removal efficiency for an outlet emission of approximately 0.05 lb/MMBtu.

Unique site issues – Existing Site. 

Contracting strategy – Multiple Lump Sum. 

The major components of the capital cost consist of equipment, field materials and supplies, direct labor, indirect 

field labor, and indirect construction costs. The capital cost was determined through the process of estimating 

the cost of equipment, components and bulk quantity. 

The cost estimates are based largely on Sargent & Lundy LLC experience on similar projects. Detailed 

engineering has not been performed to firm up the project details, and specific site characteristics have not been 

fully analyzed. We have attempted to assign allowances where necessary to cover issues that are likely to arise 

but are not clearly quantified at this time. 

Estimate Development

The cost estimates for the Low NOx Burners/Over Fired Air cases were based on a previous estimate prepared 

in 2011. Equipment costs were escalated to current pricing level. Also, material and labor have been updated to 

2012 pricing. 

Cost estimates for the SNCR technology (two cases) were based on budgetary quotes received from 

engineering and on previous estimates. 

The cost estimates for the White Bluff SCR was mainly based on similar size and scope cost estimates from 

other projects and structural takeoffs from engineering. All equipment common to both Units was divided evenly 

between the two estimates. 

The cost estimate for Lake Catherine SCR was adjusted from another cost estimate for a gas fired power station. 

White Bluff’s auxiliary boiler cost estimate for Low NOx Burners/Over Fired Air/Flue Gas Recirculation was also 

adjusted from a similar project. 

Pricing and Quantities

The data used to develop these estimates is based on using material and equipment types and sizes typically 

used in a power plant. 

Equipment and material costs were estimated on the basis of S&L in house data, vendor catalogs, industry 

publications and other related projects. In most cases, the costs for bulk materials and equipment were derived 

from recent vendor or manufacturer’s quote for similar items on other projects. Where actual or specific 

information regarding equipment specifications was available, that information was used to size and quantify 

material and equipment requirements. Where information was not furnished or was not adequate, requirements 

were assumed and estimated based on information available from project estimates of similar type and size.

Quantities contained herein are intended to be reasonable and representative of projects of this type. All 

quantity data was developed internally by S&L. Quantities were developed based on project experience of a 

plant of comparable size and then adjusted based on actual size and capacity differences and also taking into 

consideration the specific site layout based on the general arrangement drawing. While project specifics will 

certainly have an impact on these quantities, we feel they are appropriate for a study at this level. 

Labor Wage Rates

Labor Profile – Union 

Labor wage rate selected for the estimate - 2012 Union rates for Pine Bluff, Arkansas. Base craft rates are as 

published in RS Means Labor Rates for the Construction Industry, 2012 Edition. The craft rates are then 

incorporated into work crews appropriate for the activities by adding allowances for small tools, construction 

equipment, insurance, and site overheads to arrive at crew rates detailed in the cost estimate. A 1.15 regional 

labor productivity multiplier is included based on the Compass International Global Construction Yearbook. 

Labor Work Schedule and Incentives - Assumed 5x10 work week for regular work and 7x10 work week for 

outage work. 10% of the work is assumed to be outage related. 

 

Project Direct & Construction Indirect Costs

The estimate is constructed in such a manner where most of the direct construction costs are determined directly 

and several direct construction cost accounts are determined indirectly by taking a percentage of the directly 

determined costs and are identified as “Variable Accounts”. These percentages are based on our experience 

with similar type and size projects. Sales tax is specific to location. Listed below are the variable accounts. 

 Cost of overtime – 5-10’s Hour Days and Outage Work at a 7-10 Schedule 

 Subsistence (per diem) – not included 

 Consumables – 0.5% of material and labor 

 Freight on Equipment - included with equipment cost 

 Freight on Material @ 5% of material 

 Spare Parts – included with equipment costs 

 Contractors G&A Expense @ 10% 

 Contractors Profit @ 5%

Escalation

Not included. 

Contingency 

The contingency rates vary for each project based on the project’s size. The rates are based on past history of 

similar projects. This rate relates to pricing and quantity variation in the specific scope estimated. The 

contingency does not cover new scope outside of what has been estimated, only the variation in the defined 

scope. This is a composite rate and already takes into account the plus and minuses of expected actual costs. 

The rate does not represent the high range of all costs, nor is it expected that the project will experience all 

actual costs be realized at the maximum value of their range of variation. 

Exclusions

There are items that have been specifically excluded from the estimate. In order to establish the overall project 

costs, the following items must also be accounted for. This list is for information only and is not intended to be all 

inclusive. 

 Permitting costs 

 Rock excavation 

 Remediation of soil for hazardous materials 

 Power outage cost during construction 

Assumptions

 No rock excavation, no dewatering 

 Assumed that asbestos removal or lead paint abatement will not be required. 

 No obstruction for the ammonia pipe routing. 6” clearing & grubbing of existing terrain is included, no 

tree removal. 

 Directional boring underneath the existing railroad tracks is included, but with no major interferences or 

obstructions. 

 Electrical equipment and wiring installation is based on non-hazardous location. 

 Adjustments for plant unit size were made based on good engineering practice. Actual design and 

quantities may be significantly different than the quantities shown in the estimates.

Joe,

The attached PDF file contains background information on utilizing burners out of service for NOx

control, as well as, predicted Lake Catherine Unit 4 burner header pressures and NOx emissions, utilizing

the top burner elevation out of service (4BOOS). If you have any questions, please let me know.

******************************* BOOS for NOx Control.pdf 
Combustion Modification (BOOS) for NOx Control 

Implementation of Burner Out Of Service (BOOS) operation is a practical and cost-effective 

means for achieving staged combustion (i.e., modifying burner stoichoimetry to reduce NOx 

emissions formation) on an existing gas/oil fired electric utility boiler. Utilizing BOOS operation 

for NOx control is well documented in the literature, e.g., EPA 456/F-99-006R "Nitrogen 

Oxides (NOx), Why And How They Are Controlled", November 1999, and EPRI TR-108181 

"Retrofit NOx Control Guidelines for Gas- and Oil-Fired Boilers, Version 2.0", June 1997, 

among numerous others. 

The technique of BOOS operation involves terminating the fuel flow to selected burners on the 

top elevation while leaving the air registers open. The remaining burners operate fuel-rich, 

thereby limiting oxygen availability, lowering peak flame temperatures, and reducing NOx 

formation. The un-reacted products combine with the air from the above terminated-fuel burners 

to complete burnout before exiting the furnace. I have personally been involved with 

implementing BOOS operation on virtually every gas fired electric utility boiler design across 

the country since the mid 1970's. In almost every case, the original "high" burner header pressure 

(BHP) set point had to be increased to accommodate BOOS operation. No adverse operational 

or maintenance problems corresponding to BOOS implementation have been reported. 

BOOS operation can be a very effective NOx reduction technology, depending on the degree of 

staging, as shown for Ninemile Unit 4 (750 mw CE Tangential Fired) in Figure 1. The 

corresponding BOOS pattern is shown in Figure 2. The BHP corresponding to 4BOOS operation 

on Lake Catherine Unit 4 is shown in Figure 3. The "High" BHP set point would need to be 

increased from 42 to 50 psig. The predicted NOx emissions corresponding to 4BOOS operation 

are presented in Figure 4.
