RE: Formal SIP Revision To Amend Kentucky's June 25, 2008 Regional Haze SIP

Dear Mr. Melburg:

The Kentucky Energy and Environment Cabinet hereby submits to the U.S. Environmental Protection Agency

(EPA) for approval a formal revision to Kentucky's State Implementation Plan (SIP). This SIP revision addresses the

following issues that amend Kentucky's June 25,2008, Regional Haze SIP: (1) E.ON U.S. Mill Creek Units 3 and 4, a

change to indicate the proper BART Title V permit emission limits of 64.3 lb/hr and 76.5 lblhr respectively for H2SOa in

place of a 0.015 lb/mmBtu limit and (2) East Kentucky Power Cooperative (EKPC) Cooper Units I arrd 2, based on March

18,2009, revised EKPC BART determination modeling a substitution of dry flue gas desulfurization @FGD) and fabric

filtration (FF) emission controls for the wet FGD (WFGD) and wet electrostatic precipitator (WESP) conhols.

A public hearing regarding this SIP revision was conducted on November 23,2009, at the Division's main office in

Frankfort, Kentucky. Documentation regarding this public hearing and the Cabinet's Statement of Consideration, which

contains Cabinet responses to comments received during the public comment period, is proyided in Appendix N of this SIP

revision.

This SIP package includes a hard copy of the regional haze SIP narrative and appendices where changes have been

made. In addition, a DVD containing all SIP narrative and appendix changes is included. The SIP revision is also available

at the following Division website: h@://www.air.ky.gov/regs/Stateflmplementation+Plan+Revisions.htm.

Your prompt consideration of this SIP revision is appreciated. If you have any questions regarding this matter,

please contact Martin Luther at the Division for Air Quality at 502-564-3999.

7.6 Relative Contributions to Visibility Impairment: Geographic Areas of Influence for 

Kentucky’s Class I Area 

Once it was determined that SO2 emission reductions from EGU and non-EGU point sources in 

the VISTAS states would be the most effective sources to control to improve visibility at 

Kentucky’s Class I area, the next step was to identify the specific geographic areas that most 

likely influence visibility in each Class I area, and then to identify the major SO2 point sources 

located in those geographic areas. An SO2 Area of Influence was defined for each Class I area 

to represent the geographic area containing sources that would likely have the greatest impact on 

visibility at that Class I area. All SO2 point sources within these Areas of Influence were 

identified and ranked by their 2018 emissions. The following sections contain a broad overview 

of the steps in the Area of Influence analyses. See Appendix H for a more detailed discussion of 

these analyses and plots for Kentucky’s Class I area. The plots that follow are only for 

Kentucky’s Class I area since KYDAQ’s Q/d times RTMax area of influence analysis identified 

no Kentucky sources that contributed one percent or more to visibility impairment for any other 

Class I area examined by VISTAS.

9.2 Final BART Determinations 

After reviewing the sources’ BART modeling determinations and considering the statutory 

factors, KYDAQ staff has concluded that the controls proposed by all the five Kentucky EGU 

BART-Subject sources are reasonable and appropriate for addressing condensible particulates 

and their impacts on nearby Class I areas. 

9.3 BART Subject Sources in Other States Within 300 km of Kentucky’s Class I Area 

The authority and responsibility for conducting BART analyses under the regional haze rule lies 

with the state in which the BART eligible source is located. Sources must conduct an analysis of 

their impact on any Class I area within 300 km of the source. At this time the VISTAS states are 

at various points in their processes for addressing BART. For information regarding BART 

sources outside of Kentucky within 300 km of Kentucky’s Class I area, please refer to the 

governing state’s regional haze SIP submittal as it becomes available.

Louisville Gas and Electric (LG&E) and the Kentucky Energy and Environment Cabinet entered

into an Agreed Order on Octob er 20,2008 (File No. DAQ-29458-039). As specified in

paragraph I of the order, LG&E is herein providing the Kentucky Division for Air Quality with

information identiffing emission rates utilized for the modeling conducted in conjunction with

LG&E's Septembet 24,2007 submittal of Mill Creek Station's Best Available Retrofit

Technology analysis. Additionally, this correspondence provides written explanation of the

infeasibility of incorporating a sulfur trioxide (SO:) emission limitation of 0.015 lb/mmBtu into

the Mill Creek Station Title V permit.

As described in the submitted analysis, for the purpose of SO: emission determination, all HzSO+

particles determined from the CALPUFF modeling were assumed to be SO: emissions. As

shown in "TableT-l CALPUFF Modeling Parameters" of the report, the baseline HzSO+ primary

particle information are in units of grams per second (g/s), 25.39 g/s and 27 .67 g/s for Mill Creek

Units 3 and 4, respectively. When input into the CALPUFF model, they were converted to

pounds per hour (lb/hr) values of 20L5 lb/hr and2l9.6lblhr for Mill Creek Units 3 and4,

respectively. In determining the effectiveness of sorbent injection technology, a stack exit

concentration of five (5) parts per million (ppm) SO: was used to evaluate the technology's

effect on visibility impacts. For input into the CALPUFF model, five (5) ppm SO3 eeuates to

HzSO+ emission rates of 64.3|blhr and76.5lblhr for Mill Creek Units 3 and 4, respectively.

These values are displayed in Appendix D on pages D-4 and D-5 of the previously submitted

analysis. The lb/hr values were the primary model input values utilized in our CALPUFF

modeling. As such, these are the values that are appropriate for incorporation into Mill Creek

Station's Title V permit.

For illustrative purposes only, the lbftr values were converted to lb/mmBtu values in TableT-4

of the Septemb er 24, 2007 submittal. While we apolo gize for the confusion which resulted from

Appendix L.11 - 192 

Kentucky Regional Haze SIP
including the value in our submittal, we wish to clarify that we never intended to suggest that it

is appropriate for inclusion as an emission limit in our permit.

The 0.015 lb/mmBtu value provided in Table 7-4 is based on the design heat input (i.e.,

maximum) value for the two units. However, in the course of normal utility operations, the units

operate at a wide range of heat inputs, some of which are substantially lower than the design heat

input value. Although the SO: mitigation system proposed by LG&E can meet the specified

lb/hr emissions values necessary to achieve BART, it is not capable of controlling HzSO+

emission to 0.015 lb/mmBtu at all heat input levels. Indeed, the measurement accuracy of HzSO+

emissions is questionable when operating at the level of lower heat inputs that would be

encountered in the course of normal operations.

Consequently, adding a 0.015 lb/mmBtu limit to the permit would place severe constraints on

our operational flexibility which could effectively preclude us from operating the unit at certain

heat inputs. This would have major financial implications for us. In conclusion, it is not

technically feasible for our proposed SO3 mitigation system to meet the 0.015 lb/mmBtu HzSO+

target at all operating loads and we do not believe that the value reflects BART for our units.

Therefore, if the Division desires to incorporate specific BART emission limits into the Title V

permit for Mill Creek, the appropriate values would be 64.3 and 7 6.5 lb/hr HzSO+ for Units 3 and

4 respectively. If you have any questions or require additional information, please contact me at

(502) 627-4621 or Jason Wilkerson at (502) 627-4043.

RE: John Sherman Cooper Generating StationRevised BART Analvsis

Dear Mr. Luther:

As you know, Units I and 2 atthe East Kentuclcy Power Cooperative, Inc. (EKPC) John

Sherman Cooper Station (Cooper Station) are subject to the Best Available Rekofit Technology

(BART) determination guidelines under 40 CFR Part 51 . EKPC submitted its BART

determination modeling and control strategy to the Division in a report dated July 23,2007. The

July 2007 submittal identified wet flue gas desulfurization (WFGD) and wet electrostatic

precipitators (WESP) as BART for Cooper Units 1 and 2 and those controls were specified in

Kentucky's June 2008 Regional Haze SIP. Since its July 2007 submittal and the submittal of the

Regional Haze SIP, EKPC has determined, with the assistance of Burns & McDonnell

Engineering Company, Inc., that Dry FGD and Fabric Filtration (DFGD/FF) will be at least as

effective as WFGDATVESP for the Cooper Units. Therefore, EKPC is requesting that KDAQ

amend the 2008 Regional Haze SIP to allow substitution of DFGDIFF at Cooper Station for the

previously approved WFGDAMESP. Based upon our discussions with you and other

representatives of KDAQ last fall, EKPC has prepared the enclosed analysis, including modeling,

in support of this request.

After you have reviewed the enclosed submrttal, EKPC looks forward to addressing any

questions you may have. In order to comply with the obligations under the Consent Decree in the

case styled,United States v. East Kentuclry Power Cooperative, Inc., Civ. ActionNo.04-34-KSP

(E.D. Ky.) (entered Sept. 27 ,2007), EKPC must complete the retrofit of Unit 2 completed and

operational by June 30,2012.

Appendix L.11 - 1 

Kentucky Regional Haze SIP
I. INTRODUCTION

East Kentucky Power Cooperative, Inc. (EKPC) is a power generation and transmission

utility that owns and operates several electric generating units (EGUs) in Kentucky.

Some of the EGUs owned and operated by EKPC consist of coal-fired units that are

subject to the Regional Haze rule and Best Available Retrofit Technology (BART)

determination guidelines promulgated under 40 CFR Part 51. In response to EPA

rulemaking and at the request of the Kentucky Division for Air Quality (KDAQ), EKPC

previously evaluated BART for its subject EGUs and conducted modeling in accordance

with the protocol approved by KDAQ. This work culminated in the submittal to KDAQ

of the report entitled, Best Available Retrofit Technology (BART) Source Specific

Modeling - East Kentucky Power Cooperative Hugh L. Spurlock Generating Station and,

John Sherman Cooper Generating Station, dated July 23,2007 (2007 BART Submittal). '

As set out in the2007 BART Submiffal, Cooper Units 1 and 2 are BART-eligible sources

and are subject to BART since the 98th percentile visibility impacts predicted for both

BART-eligible sources were above the exemption threshold of 0.5 deciviews (dv). At the

time the 2007 BART Submittal was prepared, EKPC was in the midst of negotiating a

Consent Decree with EPA to resolve certain allegations of noncompliance with Clean Air

Act requirements, ffid it was anticipated that the negotiated resolution would require

retrofitting the Cooper BART-eligible units with wet flue gas desulfurization systems

(WFGDs) for SOz control and wet electrostatic precipitators (WESPs) for PM control.

2007 BART Submittal , at 4-3. Taking into consideration the anticipated Consent Decree,

EKPC determined at the time that WFGD and WESP were BART for Cooper Units 1 and

2. KDAQ accepted EKPC's demonstration of BART and the associated regionalhaze

modeling and utilized that information as a component of Kentucky's RegionalHaze SP,

dated June 2008. SIP, Section 7 .5.3 and Table 7 .5.3-1.

As subsequently discussed with KDAQ, the Consent Decree as ultimately entered did not

mandate WFGD and WESPs. Consent Decree, Paragraphs 64,82. EKPC retained

Burns & McDonnell Engineering Compffiy, Inc. to assist with the retrofit project for

Cooper Units I and 2, including evaluation of available control methodologies to satisfy

the Consent Decree. As a result of this evaluation, EKPC has determined that the use of

a dry flue gas desulfurization system (DFGD) combined with a pulse jet fabric filter (FF)

for Cooper Units 1 and 2 meets or exceeds the performance of the WFGD/WESP

previously proposed as BART.

As explained in detail herein, the anticipated total PM emission control achieved by the

DFGD/FF control train is better than the previously approved WFGDAMESP, and the

predicted visibility impacts are comparable.

t This request relates only to the BART-eligible sources at the John Sherman Cooper Generating Station.

The 2007 BART Submittal is still applicable to the sources at the Spurlock Station.

Appendix L.11 - 196 

Kentucky Regional Haze SIP
Accordingly, EKPC is submitting this revised BART analysis in support of its request

that KDAQ amend the June 2008 RegionalHaze SIP to allow for the substitution of the

DFGD/FF control train in place of the WFGD/IYESP.

Appendix L.11 - 197 

Kentucky Regional Haze SIP
II. ANALYSIS

A. Control Technology Comparison

In the 2007 BART Submittal, EKPC determined that a WFGD/WESP control train

capable of achieving 0.030 lb/mmBtu filterable PM and 0.052lblmmBtu total PM was

BART for Cooper Units I and 2. EKPC is requesting that it be allowed to substitute a

DFGD/FF control train capable of achieving 0.030 lblmmBtu filterable PM and 0.045

lbimmBtu total PM for the WFGD/WESP control train previously approved.

The previously approved WFGD/WESP technolo gy utllizes a lime or limestone slurrybased scrubbing medium for SOz removal in the absorber, followed by a wet ESP, which

provides removal of scrubber-generated PM as well as sulfuric acid mist. As discussed in

the 2007 BART Submittal, WFGD/WESP can provide control of filterable PM to levels

of 0.030 lbimmBtu. Total PM emissions from the WFGD/WESP control train were

estimated using the National Park Service G.IPS) PM speciation spreadsheets (see

Attachment A). At a filterable PM emission rate of 0.030 lb/mmBtu, the NPS speciation

spreadsheet for PC boilers with WFGD/WESP estimates total PM emissions to be 0.052

lb/mmBtu. These values were used in the previous BART submittal.

The proposed DFGD/FF control train utilizes a pebble lime-based dry scrubber system in

combination with a fabric filter for control of SOz, PM, and sulfuric acid mist. The

DFGDIFF can also attain filterable PM levels meeting the previously accepted 0.030

lb/mmBtu filterable PM emission rate. Condensable PM emissions from the DFGD/FF

as specified by Burns & McDonnell Engineering Company, Inc. equate to 50To of the

filterable emissions, providing a condensable PM emission rate of 0.015 lb/mmBtu for a

total PM rate of 0.045 lb/mmBtu. Based upon this information, at equal filterable PM

emission levels, the DFGD/FF actually provides better overall control for total PM than

the approved WFGD/WESP, primatily due to lower sulfuric acid emissions. The NPS

spreadsheet for WFGDiWESP determines sulfuric acid emissions (listed as inorganic

condensable PM) to be 0.018 lblmmBtu, while the NPS spreadsheet for DFGD/FF

(Attachment A) determines sulfuric acid emissions to be 0.012lblmmBtu.

Table 1 provides a summary of PM emission rates for the two control options. Based on

these rates, the proposed DFGD/FF is more effective at controlling PM emissions than

the WFGD/WESP control train identified in the SIP.

B. BART Modeling

In order to confirm and to demonstrate the equivalence of the DFGDIFF control train to

the previously accepted WFGD/WESP control train, EKPC performed additional

CALPUFF modeling to evaluate the visibility impacts in Class I areas from Cooper Units

I arrd2. PM emissions were speciated in the same manner as described in the2007

BART Submittal, except that a maximum filterable PM limit of 0.030 and a total PM

limit of 0.045 were input into the NPS speciation spreadsheets for dry-botttom PC boilers

employing FGD and fabric filtration. Emissions were then calculated using the

spreadsheets and a maximum continuous rate (heat input) (MCR) of 1,350 mmBtu/hr for

Unit 1 and 2,400 mmBtu/hr for Unit 2.2 The completed NPS spreadsheets for Cooper

Units I and 2 are included in Attachment A. Table 2 summarizes the speciated emissions

after retrofit.

Having specified exhaust parameters and calculated the speciated emission rates, the

CALPUFF model was run as described previously for Units 1 and 2 at Cooper for each

'The maximum continuous rating (MCR) for Cooper Units 1 and 2 used in the prior BART modeling were

1,080 mmBtu/hr and 2,089 mmBh/hr, respectively. (These are the MCR ratings included in the

description of these units in the Title V permit.) EKPC decided to use potential MCR values for Unit I of

1,350 mmBtuihr and 2,400 mmBtu/hr for Unit 2 in calculating emissions for the BART modeling to ensure

that the BART modeling will be valid at all operating conditions.

Class I areawithin 300 km. Table 4 shows the top eight 24-hour changes in light

extinction (deciviews, dv) from the 20 o/obest days for each of the Class I areas subject to

analysis after application of retrofit control for PM. Table 5 presents a summary of the

results of the revised BART modeling for the Cooper sources and each Class I area, with

the number of days and receptors in each Class I areawhere dv > 0.5. These tables

demonstrate compliance with the Regional Haze Rule since the 98th percentile modeled

values (8tn highest) or the 22"d highest predictions over the three y"ui. modeled,

whichever are higher, are below the exemption threshold of 0.5 dv in each Class I area.

In fact, no days in any of the modeled Class I areas out of the three years modeled was

predicted where the change in light extinction was greater than 0.5 dv. Table 6 shows a

comparison of the 2007 BART Submittal to this submittal for the 98th percentile and

marimum 24-hour change in light extinction in deciviews. As shown, with the exception

of Linville Gorge, where the 98th percentile change in light extinction goes up slightly

from 0.046 to 0.047, the visibility impacts decrease for both the 98th percentile and the

maximum Z$-hottr.

Therefore, application of DFGDIFF controls to Cooper Units 1 and 2, with a filterable

PM limit of 0.030 lblmmBtu, mitigates any adverse visibilityimpact in Class I areas

within 300 km of each source and fulfills the BART requirements.

CONCLUSION

As explained above, EKPC has determined that use of a DFGD/FF for Cooper Units 1

and 2 is at least as effective as the WFGD/WESP previously accepted by KDAQ as

BART. EKPC has performed additional CALPUFF modeling to evaluate the visibility

impacts of its BART-eligible units taking into account the alternative control train for

Cooper Units I andZ. The predicted visibility impacts are comparable to impacts noted

in EKPC's 2007 BART Submittal. Accordingly, EKPC requests that KDAQ amend the

June 2008 RegionalHaze SIP to allow EKPC to substitute the DFGDFF control train for

the previously accepted WFGDiIVESP control train for Cooper Units 1 and 2.

NOTICE OF PUBLIC HEARING 

KENTUCKY DIVISION FOR AIR QUALITY 

TO REVISE KENTUCKY’S STATE IMPLEMENTATION PLAN 

The Kentucky Energy and Environment Cabinet will conduct a public hearing on November 23, 2009, at 10:00 

a.m. (local time) in Conference Room 201B of the Division for Air Quality, 200 Fair Oaks Lane, 1st Floor, 

Frankfort, Kentucky. This hearing will be held to receive comments on a proposed revision to Kentucky’s State 

Implementation Plan (SIP). This proposed revision addresses the following issues that will amend Kentucky’s 

June 25, 2008, Regional Haze SIP: (1) E.ON U.S. Mill Creek Units 3 and 4, a change to indicate the proper 

BART Title V permit emission limits of 64.3 lb/hr and 76.5 lb/hr respectively for H2SO4 in place of a 0.015 

lb/mmBtu limit and (2) East Kentucky Power Cooperative (EKPC) Cooper Units 1 and 2, based on March 18, 

2009, revised EKPC BART determination modeling a substitution of dry flue gas desulfurization (DFGD) and 

fabric filtration (FF) emission controls for the wet FGD (WFGD) and wet electrostatic precipitator (WESP) 

controls.

STATEMENT OF CONSIDERATION 

RELATING TO A SIP REVISION TO AMEND KENTUCKY’S JUNE 25, 2008, 

REGIONAL HAZE SIP, WHICH DOCUMENTS REASONABLE PROGRESS GOALS 

FOR KENTUCKY’S CLASS I AREA MAMMOTH CAVE NATIONAL PARK AND 

INCLUDES BEST AVAILABLE RETROFIT TECHNOLOGY (BART) 

DETERMINATIONS

Amended After Comments 

Kentucky Energy and Environment Cabinet 

Department for Environmental Protection 

Division for Air Quality 

(1) The Kentucky Energy and Environment Cabinet conducted a public hearing on November 

23, 2009, at 10:00 a.m. (ET) in Conference Room 201B of the Division for Air Quality, 200 Fair 

Oaks Lane, 1st Floor, Frankfort, Kentucky. This hearing was held to receive comments on a 

proposed revision to Kentucky’s State Implementation Plan (SIP). This proposed revision 

addressed the following issues that amend Kentucky’s June 25, 2008, Regional Haze SIP: (1) 

E.ON U.S. Mill Creek Units 3 and 4, a change to indicate the proper BART Title V permit 

emission limits of 64.3 lb/hr and 76.5 lb/hr respectively for H2SO4 in place of a 0.015 lb/mmBtu 

limit and (2) East Kentucky Power Cooperative (EKPC) Cooper Units 1 and 2, based on March 

18, 2009, revised EKPC BART determination modeling a substitution of dry flue gas 

desulfurization (DFGD) and fabric filtration (FF) emission controls for the wet FGD (WFGD) 

and wet electrostatic precipitator (WESP) controls. 

Written comments were received during the public comment period. 

(2) The following individuals attended the public hearing and/or provided written and/or oral 

comments:

Response to Comments on a SIP revision to Amend Kentucky’s June 25, 2008, 

 Regional Haze SIP

 

Comment: We are concerned that the proposed BART changes for East Kentucky Power 

Cooperative (EKPC) Cooper Units 1 and 2 may result in a perceptible change in visibility at 

affected Class I areas, including Mammoth Cave National Park. EKPC is requesting to substitute 

dry flue gas desulfurization (FGD) and fabric filtration in place of the wet FGD and wet 

electrostatic precipitator that were determined to be BART in the original SIP. EKPC's BART 

modeling indicates that the change in technology should not affect visibility on the 

98thpercentile days due to particulate matter emissions. Based on the modeling results presented, 

we agree with that conclusion. However, changing control technology from wet FGD to dry 

FGD could increase S02 emissions or its dispersion characteristics. Since Kentucky is included 

in the Clean Air Interstate Rule (CAIR), we recognize that Kentucky is relying on previous 

guidance from the Environmental Protection Agency that sulfur dioxide (S02) and nitrogen oxide 

emissions controls under CAIR are better than the BART requirements. Thus, EKPC is not 

required to analyze visibility impacts of S02 and NOx in the BART determination for Cooper 

Units I and 2. However, Kentucky and EKPC should acknowledge in the SIP revision and at the 

public hearing that installing dry FGD rather than wet FGD at Cooper Units I and 2 could 

increase S02 emissions and could impact visibility at Class I areas. While modeling is not 

available to quantify the visibility impact due to a change in S02 emissions or dispersion 

characteristics, EKPC should acknowledge the potential impact. 

John Bunyak, National Park Service (NPS) 

Response: The Cabinet does not concur. EKPC Cooper does not have existing SO2 controls 

(FGD) in place. Therefore, the installation of a dry FGD for BART will result in a significant 

reduction in the source’s SO2 emissions. 

Comment: We have completed our review of the submittal and offer no comments at this time. 

Richard A. Schutt, USEPA

Response: The Cabinet acknowledges EPA’s statement.
