### Subject: Sorbent Injection Systems for Units 7 and 8 Date Issued: July 19, 2007 Location: Waukegan Generating Station, 401 East Greenwood Avenue, Waukegan, 60087



### Permit is hereby granted to the above,:.d_es1gnated Permittee to CONSTRUCT equipment consisting of a sorbent injection system to control mercury 

### emissions for each 

### of the Unit 7 and-8 boilers, 

### ·as described 

### in the above referenced 

### application. This 

### Permit**~s** 

### subject to·standard conditions attached hereto and the 

### following special condition{s}:

la. This Permit authorizes construction of sorbent injection systems for each of t-he 

### existing coal-fired bOilers for Units 7 and 8 

### (affected 

### boilers}. The new sorbent injecti-on 

### systems would control 

### mercury emissions by injecting 

### sorbent, i.e., 

### halogenated activated 

### carbon, into 

### the flue 

### gas from these existing coal-fired boilers prior to the electrostatic precipitators (ESPs) for 

### each affected boiler.

b. 

### This permit is issued based on this 

### project being an emissions control project, whose ·purpose and effect will be to reduce**emis~ions** 

### of mercury**f~orn** 

### the existing coal-fired boilers and which will not significantly"increase emissions of 

### other PSD pollutants. As such, the terms and conditions of the existing permits will continue to govern· 

### emi.!?sions and ·operation o:f the boilers except as specifically indicated.



### ii. This permit 

### is issued based on negligible particulate matter (PM) emissions from the storage and handling of sorbent for the sorbent injection systems. For 

### this purpose emissions 

### shall not exceed 0.44 tons/year. However 

### Permittee shall comply with all applicable requirements of 35 Ill. Adm. Code Part 212 that apply to the storage and handling of sorbent.



### c. This permit 

### does not authorize any 

### modifications to the affected boilers 

### or gerierating units, which would increase capacity or potential emissions.

2a. The 

### Permittee shall comply with applicable emission standarda and 

### requirements related to mercury emissions 

### for the affected boilers pursuant to 35 lAC Part 225. 1 

### Subpart B and/or Subpart F, by 

### the applicable dates specified by these rules.

### emission standards during startup 

### of the 

### boiler or the terme and conditions that 

### accompanied such authorization.

ii. To continue to operate an affected 

### boiler in violation of certain state emission standards during malfunction or breakdown of the boiler, including control devices and ancillary systems, or the 

### terms 

### and conditions that accompanied such authorization.

3. At all 

### times, the 

### Permittee 

### shall, to the 

### extent practicable, 

### maintain and operate 

### the sorbent injection systems 

### including storage and 

### handling of sorbent, in a manner consistent

### for minimizing emissions from the existing 

### coal-fired boilers and 

### the 

### source.

4a. The 

### Permittee shall comply 

### with all 

### applicable requirements of 35 IAC 

### Part 225, by

### sorbent injection systems can be adjusted remotely by 

### personnel in the 

### control room, the 

### Permittee shall install, operate, and 

### maintain instrumentation for. measuring 

### rate of sorbent injection for 

### each affected boiler with the status of the system.

Sa. The Permittee 

### shall maintain following records for the 

### coal supply for the affected boilers:



### i. Applicable records required by 

### 35 lAC Part 225, by 

### the dates specified 

### in the rules, 4elated to sampling and analysis of the coal supply to the af£ected 

### boilers for its mercury content.

ii. Records of mercury and heat content of the current coal sqpply to the affected**boilers~** 

### with supporting data for the associated 

### sampling and analysis methodology, so as to have representative data for the mercury content of the coal supply.

### 7 and 8 boilers, as described in the above referenced application. This Permit is subject to standard conditiOns attached hereto and the following special condition(s):

la. This Permit 

### authorizes construction of 

### sorbent injection systems for each of the existing coal-fired boilers for Units 7 and 8 (affected boilers). The new**so~bent** 

### injection systems would control mercury emissions by 

### injecting sorbent, i.e., halogenated activated carbon 1 

### into the flue gas from these existing coal-fired boilers prior to the electrostatic precipitators (ESPs) for each affected boiler.

b. i. This 

### permit is issued 

### based on this 

### project being an emissions control project, 

### whose purpose and effect v·dll be 

### to reduce emissions of mercury from the existing coal-fired boilers and which will not significantly increase emissions of other l?SD pollutants. As 

### such, the terms and 

### conditions of the existing permits will continue to govern emissions and operation of the boilers except as specifically indicated.

ii. 

### This permit is issued based on negligible particulate matter (PM) emissions from

Conditions**fo~** 

### the Project

1.1 

### Introduction

a. 

### i. This permit authorizes construction of a dry sorbent injection system (the affected system) on the boiler for Waukegan Unit 7 {the affected boiler)

. This system 1-lould be designed to inject 

### Trona (a rr.ineral form of sodium 

### carbonate and sodium 

### bicarbonate) into the duct 

### work. at a 

### point prior to the**elect~ostatic** 

### precipitator**(ES~)** 

### of the affected boiler to control 

### tbe suliur dioxide (SOt) 

### emissions of the 

### boilei.

ii. 

### This permit also authorizes 

### conversion 

### of the existing 

### ESP
to 2. ''cold-side" design, \-lith the ESP being downstream of 

### the air 

### heater. This change will improve the control efficiency 

### of the ESP which controls particulate matter (PM) emissions from affected boil_er. This is because the reduction in the temperature of the flue gas through the 

### air heater will decrease the actual gas 

### volume, thereby increasing the gas residence t.ime in the ESP. In addition_, injection of sodium based dry 

### sorbent.s, ·as planned may reduce resistivity of the 

### fly ash resulting in improved**ES~** collection 

### effici-ency. It will also 

### irnprove the effectiveness of control of mercury emi5sions 

### by the activated 

### carbon injection system 

### on the affected boiler.

### Illinois' t-lSSO.M rules (35 IP..c Part 203). This is becauge 

### the increases in emissions of · 

### individual 

### t;ollutants from these 

### units are less than tile 

### significant emission rates set in 

### these rules.

b, The Illinois EPA bas determined that the changes to the affected boil€r, 

### as described in the application, will not constitute a modification of the boiler under the federal New so.urce Performance Standards, 40 CFR 60 because the changes have the 

### primary function Of reducing emissions 

### and therefore are not**considered~** 

### modification pursuant to 40 CFR 

### 60.14(e} {5).

Dear Mr. Kormos:

On behalf of Midwest Generation, LLC, ("MidwestGen"), I am writing to provide nolice of MidwestGen's intent to decommission Fisk 

### 19. MidwestGen seeks PJM's determination that the unit could be relired as early as the date upon which we receive PJM approval (i.e. 30 days from today), but no later than December 

### 31, 2012.

MidwestGen provides this notice pursuant to the PJM Open Access Transmission Tariif ("OATT"), Part V "Generation Deactivation". MidwestGen believes that under the standard of review for plant retirements, there are no reliability issues associated with MidwestGen's retirement of this unit.

In order to facilitate MidwestGen's retirement plan, we are requesting that PJM proceed now with a thirty 

### (30) day reliability review as contemplated in the PJM OATT, Part V, and section 

### 113.2.

We would be pleased to discuss this matter further with you and look forward to hearing from you. Please feel free to contact Reem Fahey

Three electric utilities operating in Illinois, Dynegy, Ameren, and Midwest Generation have
committed to comply with the MPS and CPS under the Illinois Mercury Rule, requiring the

installation ofstate-of-the-art pollution controls on many oftheir electric generating units in

## Electronic Filing -Received, Clerk's Office, 04/10/2012 *****PCB2012-121 *****

lllinois. These regulations were promulgated to allow coal-fired electric utilities more flexibility

in meeting the lllinois Mercury Rule in exchange for significant NOx and SO, reductions. Appendix C contains the relevant portions ofthe fully adopted Illinois Mercury Rule, with the requirements for NOx and 

### S02 

### emission reductions highlighted. Illinois intends to submit Appendix C to USEPA, the highlighted portions ofwhich will become part ofIllinois' SIP to satisfy BART obligations for affected units atthese three utilities. 

### In addition, the MPS and CPS requirements will ultimately be contained in federally enforceable permits.

The MPS and CPS require affected utilities to meet fleet-wide average emission rates, which 

### will require instaJiation ofcontrols on emission units regardless ofwhether or not they are subject to
BART. The agreements between Tllinois and the utilities are intended to allow the companies the flexibility to meet the fleet-wide emission limits in the most cost-effective manner. T;he
agreements contain 

### a range ofcompliance dates, beginning 

### as early 

### as 2012 and 

### as late as 2019.

The Illinois EPA recognizes that, in general, the compliance date for BART controls is within 5

years ofUSEPA's approval ofthe State's SIP. AssumingUSEPA approves Illinois' SIP in 2011

or 2012, the compliance date for BART eontrols would be irr2016 or2017. The Illinois EPA's analysis ofemissiorr reductions that will result from implementation oftheMPS·and CPS by the

year 2015 demonstrates conclusively that Illinois' approach 

### will yield much larger reductions of 

### NO, and 

### S02 than will implementation ofBART controls onjust subject to BART emission

units. Emission reductions occurring after 2015 will improve visibility in Class 

### I areas impacted by sources in lllinois, regardless ofUSEPA's decision ofwhetherto approve those reductions as meeting BART requirements. The following subsections provide Illinois EPA's analysis ofthe

emission reductions expected from the MPS and CPS and a description ofthe controls that 

### will

most likely be installed as a result 

### ofthe MPS and CPS.



### 4.1.1.1 Dynegy Dynegy operates several electric generating stations in Illinois, all ofwhich are affected by the requirements ofthe MPS. Only the three coal-fired boilers at Baldwin are subject to BART,

however. Units I and 2 at Baldwin are cyclone-tired boilers burning sub-bituminous coal, while

Unit 3 is a tangentially-fired unit burning sub-bituminous coal. Currently, Units I and 2 are
controlled by over-fire air ("OFA") and selective catalytic reduction ("SCR") for NO,, while

### 4.1.1.3 

### Midwest Generation

Midwest Generation operates 19 coal-fired EGUs at six separate locations in Illinois. Nine of
these units, located at Powerton, Joliet, and Will County, are subject to BART.

Powerton

All four units at the Powerton station are subject to BART. All four ttnits are cyclone-type
boilers firing sub-bituminous coal and vent to a common stack. Current

consists oflow-NO, burners and OFA. Midwest Generation is expected to install selective noncata1)1ic reduction (SNCR) controls on all four units by 2012. The units currently bum lowsulfur coal to control for SO,, but Midwest Generation currently plans to install 

### flue gas
desulfurization (FGD) equipment by the end of2013 on 

### all four units.

Joliet
Four ofthe 

### five units (Units 71, 72, 81, 

### and 82) at the Joliet facility are subject to BART. The
four units ofinterest are all tangentially-fired boilers burning sub-bintminous coal. Current NO,
controls for Boilers 71, 72, 81, and 82 consist oflow-NO, burners and OFA. Midwest
Generation is expected to install SNCR controls on these four units by 2012. For SO,, Midwest
Generation is expected to install FGD equipment on all lour BART units at Joliet by 2019.

Will Countv
Ofthe four units at the Will County plant, only Unit 4 is subject ro BART. Unit 4 is tangentially
tired and burns sub-bituminous coal. NOx emissions from Unit 4 are currently controlled by low-NO, bumers and OFA. Midwest Generation is expected to install an SNCR on this unit by
2012. For SO,, Midwest Generation is ex.pected to install FGD equipment by 2019.

It should be noted that under the CPS, Midwest Generation is not required to meet unit specific
emission limits for NO, or S02, 

### and that the anticipated CPS emission estimates given in Tables

4.6 and 4.7 reflect the fleet-wide average emissions for all units. Tables 4.6 and 4.7 show that
the CPS will lead to 

### system-wide reductions ofmore than 38,000 TPY ofNO, and more than 35,000 TPY ofSO, by 2015, which are much greater than the reductions that would be achieved by meeting the presumptive BART emission levels at the subject-to-BART units.

4.1 

### .2 Other Illinois EGUs
The l'v!PS and CPS requirements do not apply to Dominion Kincaid or to CWLP. The Illinois

EPA has negotiated separate agreements with these companies to address the BART requirements. Consistent with these agreements, both plants have either installed controls or plan to install controls that will meet or exceed the presumptive BART limits. Unit-specific requirements for these sources are contained in federally-enforceable permits, which are included

### 4.1.2.1 CWLP

The subject-to-BART units at CWLP are Dallman 31, Dallman 32, and Lakeside 8. CWLP shut
down the Lakeside unit in 2009. The Dallman 31 and 32 units are cyclone boilers and burn
bituminous coal. CWLP currently operates SCRs and scrubbers on both Dallman units. It

should be noted that CWLP's generating capacity is less than 750 MW, so the presumptive B.'\RT emission limits shown in Table 4.1 do not apply, Rather, the BART rule requires that
such units operate SCRs, or equivalent controls, to control 

### NO, emissions on an annual basis.
For SO,, the BART rule requires 95% emissions reduction.

# m. \\That arc the requirement!> for regional haze SIPs?

Regi anal haze SIPs must assure reasonable progress tO\\'ard tlw national goal of achieving natural visibility conditions in Class I areas. Section 1G9A ofthe CAA and EPA's implementingregulations require .states to establish long·term strategies for making ronsonabla progress toward meeting this goal. Plans must also give specific attention to certain stationary

sources that wero in existence on i\ugust 7, 1977, bul were not in operation before August 7, 1962, and must roqu.i:re those sources to install emission controls reducing visibiltty impairment if appropriate. The specific regional haze SIP requimmenls are discussed in further detail below.
A. Detennination 

### of BaseHneJ Natural, and Current \lfsibiliiy Conditions



### The RHR establishes 

### the dociviewJ (dv) as**tht~JJrinr::ipa]** metric or unit for V>.:pressing visibility impairment. This visibility metric expresses uniform proportional changes in haziness in terms ofcommon increments across the 

### entire rRllge ofvisibilit}r conditions. from pristine to extremely hazv conditions. Visibility 

### ex.Pressed in deci;news is determinedby using air**qu~tty_measurements** to estimate light extmctlon and then transforming the value of lightextinction using a logarithm function. The dociview ls a
more useful measure for 

### trading proglt'.ss in improving visibility than light extinction itselfbecause each deciview change is an equal incremental change in**\~isibility** perceh>ed by the human eye. Most people can detect a change in visibility at one deciview.

The deciview is used in expressing RPGs, defining baseline, current, and

The regional haze SIPs must contain measures that ensure "reasonable progress" toward the m1tionaJ goa] ofpreventing and remedying visibility irnpairment in Class 

### I areas caused 

### by anthropogenic c!.ir pollution. The national goal is a :roturn to natural conditions such that anthropogenic sources ofair pollution would no longer impair visibility in Class I areas.

To track changes in visibility 

### over time at onch ofthe 1SG Class! areas covered by the visibility program (40 CFR 01.401-437) and 

### as part ofthe 

### precess for doterrnining reasonable 

### progress, states must calculate the**de~'l"ee** ofexisting visibility impairment at each Class I anm at the time of**er:~ch** regiouul haze SIP submission and a[ the progress review every five years, miclway through each lO·year implementation pariad. The RHR requires states \vith Class I areas**(Cias~** I states) to determine tho degree of impairment in deciviews fo!the average ofthe 20 percent least impaired**[b~st)** and 20 ,petcent most impaired (worst) visibility days over a specified time pariod at each of its CJnss J aroas. Each state must also**de~,.elop** nn estimate of natural visibility condltions for the purpose ofcmnpariug progress toward the national goal. Natural visibility is determined 

### by estimating the natural concentrations ofpollutants that cause visibility impairment and then calculating total light extinction based

on those estimates.

B. Determination of Reasonable Progress 

### Goals {RPGs)

The vehicle for eDsuring continuing progtes::; towards achieving the natural visibility 

### goal is the submission of a series ofregional haze SIPs from the**s-tate~** that establish two distinctRPGs,

one for the best days o.nd one for the worst days 

### for every Class I area for each approximately lO·year implementation period, The RHR does not mandata specific milestones or rates ofprogress, but instead calls 

### for states to estnblish goals that provide for ''reasonable progress" toward achieving natural visibility condi.Uons. 

### In settingRPGs, Class I states mustprovide for an improvement in visibility for the worst days over the approximntdy 10-year pariod of tha SIP and ensure no degradation in visibility for tho bast days.

Class I states have significant discretion in establishing RPGs, but are required to consider the following factors established in section 16£1A of the C/>.11. and in EPA's RHR et 40 

### CFR 51.30B(d)(l)(i)(A): (1) The costs of compliance; {2) the time necessary for compliance: (3) the energy and non·air qualitv environmental impacts of campfiance; and, (4) lhA romaining useful life ofauy potentially affected

sources. The state must demonstrate in its

### 3969

In setting RPGs, each Class I state must also consult with potentially contributing states, i.e. those states that may affect visibility impairment at the 

### ClaSs I state's areas. 40 CFR 51.308(d)(1)(iv).
C. BestAvailable Retrofit Technology (BART)

Section 169A of the CA..A... directs states to evaluate the use ofretrofit conh·ols at certain older large stationary

sources to address visibility impacts from these sources. Specifically, CAA section 169A(b)(2)(A) requires states to revise their SIPs to contain such

measures as may be necessary to make reasonable progress towards the natural visibility goal including a requirement that certain categories of existing mnjor stationary sources built between 1962 and 1977 procure, install, and operate BART as determined by the state. The set of "major stationary sources" notentially·subjer.:t to BART is listed in 

## t:AA section 169A(g](7). The state can require source-specific BART controls, but it also hns the flexibility to adopt an alternative such as a tiading program as long as the alternative provides greater progress towards improving visibility than BART.

On july B, 2005, EPA published the Guidelinesfor BARTDeterminations Under the Regional Haze n.ule at Appendix Y to 40 GFR Part 51 (BART Guidelines) to assist states in determining which oftheir sources should be subject to the BART requirements and in determining appropriate emission limits for each applicable source. A state must use the approach in the BART Guidelines in making a BART determination for fossil fuel-fired electric generating units (EGUs) with total generating capacity in

excess of 750 megawatts. States are encouraged, but not required, to follow the BART Gnidelines in making BART determinations for other sources.

States must addl·ess aJl visibilityimpairing pollutants emitted

### by a source 

### in the BART determination 

### process. The most significant visibility impairing pollutants are SO,, NOx. and PM. EPA has stated that states should use their bestjudgment in determining whether VOC or NH3 compounds impair visibility in Class I areas.

States may select an exemption threshold value for their BART modeling under the BART Guidelines, below which a BART-eligible source 

### ""-'Ould not be expected to cause or contribute to visibility impairment in any Class I area. The state must 

### document this exemption threshold value in the SIP and must state the basis for its soloclion of U1nt vc.luo. The exemption threshold set 

### by the state should not be higher than 0.5 dv. Any

source 

### v..-ith emissions that model above the threshold value would be subject to
a BART determination review. The BART Guidelines acknowledge 

### va..--ying circumstances 

### affecting different Class I

areas. States should consider the number 

### ofemission sources affecting the Glass I areas at issue and the magnitude ofthe individual source's impact.

Tho state must identify potential 

### BART sources in its 

### SIP, described as "BART**~eligible** sourcos" in the RHR, and document its BART control determination analyses. In making BART determinations, section 169A(g](2] ofthe GAA requires the state to consider the following factors: (1) The costs of compliance; (2) the energy and non·air quality environmental impacts ofcompliance; (3) any existing pollution control technology in use at the source: (4) the remaining useful life oftho source; and, (5) the degree of improvement in visibility which may reasonably be anticipated to result from 

### the use 

### of such technology. A regional haze SIP must include source-specific BART emission lim.its and compliance schedules for each source subject to BART. The BART controls must be installed and in operation as expeditiously as practicable, but no later than five years after the date ofEPA's approvaJ ofthe state's .regional haze SIP. CAA section 169(g)(4); 40 GFR 51.308(e][1)[iv). In addition to what is required by the RHR, general SIP requirements mandate that the SIP must also include 

### all rogulatory requirements related 

### to monitoring. reco:rdkeeping, andreporting for the DART controls on the source. D. Long-Term Strategy

Consistent ·with the roquirement in section169A(b] ofthe CAA that states include in t11eir regional 

### haze SIP a 10 to 15 year strategy for making reasonable progress, section51.308(d](3] of 

### the RHR requires that states include

a long-term strategy (LTS) in their regional haze SrPs. The LTS is the compilation ofatl control measures a state 

### will use during the implementation period ofthe specific SIP submittal to meet applicable RPGs. The LTS must include enforceable emissions Umitatioos, compliance schedules, and other measures as necessary to achieve the RPGs for all Class I areas \"lithin or affected by emissions from the stare. 40 CFR 51.30B(d][3).

\'\Then n state's emissions are reasonably anticipated to cause or conlribute to**vl~ibiliLy** impairment in a Class I area focated in another state, the RHRrequires the impacted state to coordinate 

### with the contributing states in order to develop coordinated emissions management strategies. 40 CFR 51.308(d](3](i). in such cases, the contributing state must demonstrate that it has included in its SIP all

measures necessarv to obtain its share of lhe emission reduCtions nooded to meat the RPGs for the Glass I area. The RPOs havo provided fonuns for significant interstate consultation, but additional consultations between states may be requited to address interstate visibility issues sufficiently,

States should Consider all types of anthropogenic sources ofvisibility impairment in developingtheir LTS, including statiomuy, minor, mobile, and

area sources. At a minimum, states must describo how each ofthe follov.fing
seven factors are taken into account in developing their LTS: (1) Emission reductions due to ongoing air poUution control programs, including measures to address RA VI; (2) measures to mitigate the irnoacts ofconstruction activities; (3) emissions limitations and schedules for compliance to achieve the RPG; (4)

source retirement and replacement schedules; (5) smoke management techniques for agricultural and forestry management purposes including plans

as currently exist within the state for these purposes; (6) enforceability of emissions limitations and control measures; and, (7) the anticipated net effect on visibility due to projected changes in point, area, and mobile

source emissions over the period addressed by tho LTS. 40 GFR 51.308[d](3](v).
E. Coordinating Regional Haze 

### and ReasonablyAttributable Visibility ImpairmentLong·Term Strategy

EPA revised 40 GFR 51.306(c) as part ofthe RHR regarding the LTS for RAVI ·to require that the RAVI plan must provide for a periodic review and SIP revision not less frequently than every three years unti1 the date of submission of the state's first plan addressing regional haze visibility impairment in accordance with 40 GFR 51.308(b) and (c). The stnte must revise its plan to provide for review and revision ofa coordinated LTS for addressing RAVI and regional haze on or before this date. It must also submit the first such coordinated LTS with its first regional haze SlP.

Illinois has a distinctive situation reaardi.ng CALR, insofar as it has alopted state rules that rr:quirC3 EGUs to control NOx and S02 emissions beyond the control expected from CAIR, even in the absence ofCAll\ 1 particularly 

### by 2018 and beyond. Further discussion of these Illinojs rules is provided below. The RPGs thatpertinent Class I states have adapted are predicated on other contributing states achieving 

### the EGU emission reductions anticipated under CAIR. Since Illitwis is mandating a greater degree ofcoutrol than is expected from other states, EPA concludes that Illinois's regional haze plan is expected to provide emission reductions representing an appropriate contribution toward meeting tha RPGs for the affected ClRss I nreas, irrespective of tho status ofCAIR and irrGspective of the associatod issues regarding the adequacy of other state's plans. For similar reasons, EPA bnlieves that the approvability of the Illinois pion js Hlso not affected by the status of tho Transport Rule, which was promulgated ou August a, 2011 al 76 FR. 48200 and stayed on December 30, 2011.


### D. BestAvailableRetrofit Tachnalagy

States are required to submit an irnplemontation plan containing emission limitations representing BART and schedules for compliance with BART for each BART-eligible source that may reasonably be anticipatedto
cause or contribute to nny impairment in a Class 1 area. unless tl11:1 State demonstrates that an emissions trading program or other alternative 

### will achieve greater reasonable progress towHrd natural vi.sibilitv conditions. 40 CFR 51.300(e). •

Using the criterin in the BART Guidance at 40 CFR 51.308(a) and Appendix Y, Illinois·first identified all ofthe BART·eligible sources and**asse~sed** whether the BART-eligible

sources were subject to BART. nlinoi.s initially identiflad 26 potential BART facilities-11 EGUs, four petroleum
ren**ne1:1~s,** Utree cl1em\cal process plants, two Portland cement plants, two ulnss fiber processing plants, one lime Plant, and one iron and steel plant. The state further analyzed these facilities to idantify those sources subject to BART. Illinois relied on modeling conducted by MRPO using a modeling protocol MRPO developed. MRPO conferred with 

### its states 1 EPA, and the FLMs in developina its B1\RT modeling protocol. EPA

### guid~ce says that, "any threshold lhat you use for determining whether a
source 1COntributes' to visibility impairment should not be higher than 0.5 dv." The Guidelines affirm that states are free to use a lower threshold if the locution of a Iorge number of**BART~eligible** sources in proximity of a Class I aroa justifles this approach. ltlinois: used a contribution threshold of 0.5 dv for determining which sources W1Urant being subject to BART. Illinois concluded that the threshold of0.5 dv

was appropriate since its BART-eligible

souxcss are located**state~wide** and no Class I areas are nearby causing Illin_ois to correctlv conclude that a strictor contributiOn threshold is not justifled. The modeled impact oftheso fac:iliti'es indicated that 11 sourcas have at least 0.5 dv impact (98th percentile) and thus ai-e subjectto BART. The 11sources determined to bo subject to BART are nine EGUs and two petroleum rafinaries. The other 15 potential BL\RT

sources were deterlnined notto be subjectto BART because the analysis showed impacts well below the 0.5 

### dv contribution threshold.

The EGUs subject to BART are: • Dynegy Midwest

To address mercu.ry emissions from EGUs. Illinois adoptod Part 225 of Illinois's air pollution regulations, entitled "Control ofEmissjons from Large Combustion Sources," 

### Tn tllis rule, Illinois offered affected liti.lities'two options, one ofwhich imposes stringent limits on mercury emissions alone and the other of which mandates implementation ofspecific mercury control technology in conjunction with satisfaction of stringent emission limits for S02 and NOx. Part 225 includes section 225.233J entitled "MultiPollutant Standards,'' addrGssing emissions from facilities m¥ned 

### by Ameren and Dynegy, and sections 225.293 to 225.299, collectively referred to as tho Combined Pollutant Standards (CPS), addressing emissions**~om** . fadlitios owned by Mid\\'est Generation.

rn all cases, the utilities ha\·e selectE:ld the option including mercury control toclmology and applicability ofthe SO, and NOx limits. The emission lirnit.'l are in the earlier 11oted sections ofthe stato rules, so tl1ese 802 and NOx limits are now fullv enforceable by the state.

Tho 

## srJ

.. and NOx emission limits in Part 225

### ~les reflect substantial averaging across units and across

. facilities. For exantple, the collectivo set offacilities in Illinois owned by Midwosl Generation {as listed in the Part 225 rules] are subject 

### to NOx and S02 limits bused on annual average emissions across all facilities. The limit for NOx emissions is 0.11 pounds per million British Thermal Units (lb/ MMBTU) starling in 2012 and the limits for 

## so, are 0.15lb/MMBTU in 2017 and 0.11 IbiMMBTU starting in 2019. The collecti\•e set ofAmt!rG-n facilities in 1Uinois, under the: Multi*Pollutant Standards (MPS), 

### mu!>t meet 

### an annual average omission limit for NOx of 0.11 lbiMMBTU stwting in 2012 and for S02 of0.23 lb/MMBTU starting in 2017. Similar limits under the MPS apply to the Dyuegy facilities in l!Hnois.

EPA b(lliGves this degree 

### ofaveraging is accaptable inthis conte>.i. The limits that Illinois has imposed are sufficiently strlngent that the companies have only limited latitude to O\'er control at some faciliti.es in trade for having elevated Gmissiom.· at other facilities. The facilities ownedby each company are sufficiently close to each other, relative to their distances from the nearest Class I areas, that m:Jdest shifts in emissions from one facility to another should havs minimal impact on the comhined impact onragionnl haze attho Closs l

nreas. Furtherm,ore, regional haze is evaluated across a considerable number ofdays, e.g., the 20 percent ofdays with the worst visibility. Therefore, a limil that allows elevated emissions au individual days, so long as other days have lower**emissions~** should suffice to address the pertinent measures of regional haze. IlHnois's limJts should also be adequotely enforceable since the

sources at issue Bro required to conduct continuous emission mnnitorin_g ofboth SO, and NOx.

A consent decree between the United States and Cfl'GO Petroleum Corporation was entered in the U.S. District Court for the Southern District ofTexas on October 6, 2004 (No. H-04- 3883). The consent decree requires the company to operate SCR and a wet scmbbing system at its Fluid Catalytic Cracking Unit (FCCU] that wUII·educe NOx emissions by more than 90 percent and SD2 omissi:::ms by 85 percent. The co·ntrols on the FCCU will result in a reduction ofNOx. omisslous from 1,065.7 to 106.6 TPY and 802 emissions from 10,982.5 to 107.9 TPY by 2013. CITGO has also added a tail gas recovery o.nit that reduces SOz emissions from its sulfur train units from 4340.0 to 91.2 TPY, a 98 percent reduction. The emission controls on all units at GITGO's Lemont refmery will reduce NOx emissions by 1,268 TPY and S02 emissions by 15.123 TPY.

EPA is satisfied with the state's BART d(l1ermiootions. The emission limits that Illinois adopted generally '\•.rill require state-of-tho-art omission controls, not just .at the units subject to BART requirements bul also at numerous units that aro not subject to BART, The Illinois facilities subject to BART are a long distance from any Class 1area such that, so the geographical redistributions ofemissions witlrin Illinois do not sign.ificantly affect visibility and the benefits ofa1ternate control stratagics may bejudged simplJ• by compnriug the net emission reductions. The MPS and CPS provide emiss-ion reduction well in

Illinois did not rely on the Clean Air Interstate Rule (CAJR) for its BART determinstions.lllinois is in the CAIR region. However, it used its stat-e rules, permits, und consent decrees to achieve emission reductions tha.t SAtisfy
