Proposed Rule. Proposal for Public Comment. 

OPINION AND ORDER OF THE BOARD (by J.A. Burke): 

This rulemaking updates the ambient air quality standards in the Board's air pollution 

regulations (35 Ill. Adm. Code 243) to include revisions to the National Ambient Air Quality 

Standards (NAAQS) 1 adopted by the United States Environmental Protection Agency (USEP A) 

pursuant to section 109 of the Clean Air Act (CAA) (42 U.S. C.§ 7409 (2011)) during the period 

Janumy 1, 2013 through June 30,2013 and on July 3, 2013 and August 5, 2013. Today's action 

proposes the first update to the initial amendments undertaken by the Board to fulfill a new 

identical-in-substance mandate adopted in P.A. 97-945 (eff. Aug. 10, 2012) to ensure that 

Illinois' regulations reflect USEPA's most recent NAAQS. The Board adopted the initial 

amendments in National Ambient Air Quality Standards. US EPA Regulations (through 

December 31. 2012). R!3-11 (July 25, 2013), which were effective on July 29,2013. See 37 Ill. 

Reg. 12882 (Aug. 9, 2013). 

Today the Board adopts a proposal for public comment that would mnend segments of 

the Illinois ambient air quality standards to reflect revisions and USEPA actions that affect the 

federal NAAQS codified in 40 C.F.R. 50. As explained below, the Board intends the Illinois 

mnbient air quality standards adopted in this proceeding to be identical-in-substance with their 

federal counterparts, as "identical-in-substance" is defined by Section 7.2(a) of the 

Environmental Protection Act (Act) ( 415 ILCS 5/7.2(a) (20 12)). 

Section 10(H) of the Act (415 ILCS 5/lO(H), as added by P.A. 97-945 (eff. Aug. 10, 

2012)), mandates this rulemaking requiring the Board to "adopt ambient air quality standards 

specifying the maximum permissible short-term and long-term concentrations of various 

contatninants in the atmosphere; those standards shall be identical in substance to the national 

ambient air quality standards promulgated by . .. the United States Environmental Protection 

Agency in accordance with Section 109 of the Clean Air Act [(42 U.S.C. § 7409)]." 415 ILCS 

511 O(H). In addition, Section 9.1 (e) of the Act requires the Board to conduct this rulemaking 

pursuant to Section 7.2(b) of the Act (415 ILCS 5/7.2(b) (2012)) for adopting rules that are 

"identical in substance" to the federal requirements. 

1 Throughout this opinion and in the regulatory text, the Board uses the abbreviation "NAAQS" 

to refer to a single standard and "NAAQS" to refer to multiple standards. 
2 

Section lO(H) of the Act (415 ILCS 5/lO(H) (2012)) and Section l -5(c)(l) of the 

Administrative Procedure Act (AP A) (5 ILCS 1 00/5-1-5( c)( 1) (20 12)) also provide that Title VII 

of the Act and Section 5-35 of the APA (5 ILCS I 00/5-35 (2012)) do not apply to this 

proceeding. Accordingly, the Board will not adopt a "First Notice" proposal, or a "Second 

Notice" proposal for review by the Joint Committee on Administrative Rules (JCAR). However, 

as provided in Section lO(H) of the Act, and as explained in the two following segments of this 

opinion and order, the Board, before adopting final rule amendments, will provide notice of this 

mlemaking proposal in the Il

inois Register, hold one public hearing on the proposal as required 

by the federal Clean Air Act (33 U.S.C. § 741 O(a) (20 II)), and allow for public comment. 

The Board reserved this docket to accommodate amendments that are necessary to update 

the Illinois ambient air quality standards to reflect revisions and USEP A actions that affect the 

federal NAAQS during the period January I, 2013 through June 30, 2013. For reasons explained 

below, the Board has included amendments to accommodate USEPA actions that occurred on 

July 3, 2013 and August 5, 2013. Board action is necessary to amend the Illinois ambient air 

quality standards to conform with the NAAQS adopted and amended by USEP A. 

The Board prefaces this opinion with procedural matters. First, the Board provides 

information on the public comment period. Second, the Board describes facts relative to a 

scheduled public hearing for this proceeding. Third, the Board sets f011h the timetable for 

completing this rulemaking. The substantive discussions follow the procedural matters. 

PUBLIC COMMENTS 

The Board invites public comment on the proposed amendments. The Board will receive 

public comments until at least 45 days after a notice of these proposed amendments appears in 

the Ilinois Register. Anyone may file a public comment with the Board at:

After the hearing and public comment period, the Board will promptly issue an opinion 

and order adopting final mle amendments. The Board will then file the amendments with the 

Office of the Secretary of State, and a Notice of Adopted Amendments will appear in the Ilinois 

Register. Any Agency submission of the associated SIP revision to US EPA will follow that 

Notice. 

DUE DATE AND S CHEDULE FOR COMPLETION 

The Board must complete action to adopt amendments within one year of the date when 

USEPA has revised the NAAQS. 415 ILCS 5/7.2(b). Since USEPA adopted the first set of 

amendments included in this proceeding on January 15, 2013, the Board must complete 

corresponding amendments before January 15, 2014. The Board can fulfill the one-year mandate 

in advance of the January 15, 2014 due date according to the following schedule: 

Due date: 

Proposal adopted date: 

Publication submission deadline:

This estimated timetable of intermediate activities towards completion of the 

amendments has time added to allow for any minor unforeseen delays in finalizing the 

amendments in advance of the statutory due date. It is possible that progress toward completion 

could occur more slowly-up to the statutory deadline of January 15, 2014-due to presently 

unforeseen events. 

OVERVIEW OF THE FEDERAL NAAQS AND THIS PROCEEDING 

The amendments proposed today are intended to make the Illinois ambient air quality 

standards identical-in-substance to the NAAQS adopted by USEP A. Today's proposal includes 

US EPA revisions and ancillary actions, such as USEP A approvals of reference methods and 

equivalent methods, during the period January 1, 2013 through June 30, 2013. The Board 

included later federal actions that occuned on July 3, 2013 and August 5, 2013, as described 

below. 

Docket RI4-6: Januarv I, 2013 through June 30, 2013 Amendments 

USEPA amended the federal NAAQS once during the period January 1, 2013 through 

June 30,2013. In addition to the amendments to the NAAQS, USEPA updated the document 

"List of Designated Reference and Equivalent Methods" (List of Designated Methods) on June 

27, 2013. The List of Designated Methods is essential to implementation of the NAAQS. Board 

action is required on both USEPA actions, as is summarized below: 

Januarv 15, 2013 (78 Fed. Reg. 3 086): Adoption of new 2012 Primarv 24-Hour and 

Annual Average NAAQS for PM, 5 

Description of the US EPA action: US EPA adopted the new 2012 primary 24-

hour and annual average NAAQS for PM2.5• USEP A further revised the 

interpretation of the NAAQS for PM25• 

Prospective necessarv Board action in response: The Board must incorporate the 

new NAAQS and revised inte1pretation into 35 Ill. Adm. Code 243. 

June 27, 2013: Update to the List of Designated Methods 

Description of the USEP A action: USEP A updated the "List of Designated 

Reference and Equivalent Methods." 

Prospective necessary Board action in response: The Board must update the 

incorporation by reference to this new version of the List. 

Later USEPA NAAQS-Related Actions oflnterest 

The Board engages in ongoing monitoring of federal actions. As of the date of this 

opinion and accompanying order, the Board has identified two USEP A actions since June 30, 
6 

2013 that further affected the NAAQS in a way that would require Board attention. The Board 

believes that expedited consideration of these USEP A actions would confer two benefits: (I) 

expedited consideration could aid implementation of the Illinois ambient air quality standards; 

(2) expedited consideration could obviate action in the next NAAQS update for the period July I, 

2013 through December 31,2013. The two later USEPA actions are the following: 

Julv 3, 2013 (78 Fed. Reg. 4 0000): New FRM for Lead in Total Suspended 

Particulate Matter 

Description of the USEPA action: USEPA amended appendix G to 40 C.F.R. 50 

to establish a new FRM for measuring lead in total suspended pmticulate matter 

for the purposes of the lead NAAQS. 

Prospective necessarv Board action in response: The Board should update the 

incorporation by reference to appendix G in Section 243.108 by adding a Federal 

Register citation to this action to incorporate the changes into the Illinois 

regulations. 

August 5, 2013 (78 Fed. Reg. 47191): Area Designations for Two Areas in Illinois 

Under the 2010 Primarv Annual Average and 24-Hour NAAQS for Sulfur 

Oxides 

Description of the USEP A action: USEP A made area designations for the 20 I 0 

NAAQS for sulfur dioxide. 

Prospective necessarv Board action in response: The Board should outline that 

this action does not impact the continued viability of the 1971 annual average and 

24-hour primary NAAQS for sulfur oxides. The Board must modify the Board 

note appended to 35 Ill. Adm. Code 243.122(a)(5), which states that USEPA has 

not designated areas for the 20 I 0 NAAQS and mentions a 20 II Agency 

recommendation for area designations. 

Summarv Listing of the Federal Actions 

Upon Which Action is Required in This Docket 

Based on the foregoing, the two federal actions that form the basis for Board action in 

this update docket are the following, listed in chronological order:

Average and 24-Hour NAAQS for 

Sulfur Oxides 

The Context of This Identical-in-Substance Proceeding 

The Board does not engage in substantive review of federal standards in the context of an 

identical-in-substance proceeding. Rather, the Board reviews federal standards only to the extent 

necessary to make a "best fit" for those standards in the context of the Illinois regulatory scheme. 

The Board tries to follow the structure and content of federal regulations where possible. 

Tlus ensures the full incorporation of all necessary elements of the present federal standards, and 

it makes updating the regulations easier when future federal amendments occur. 

Depattures from the federal structure may occur for a variety of reasons and will be noted 

as needed below. Where more sttingent pre-existing State standards exist that will continue in 

effect after incorporation of federal elements, the Board will incorporate a structure that retains 

those State standards. See, e.g., RCRA Subtitle D Amendments (Amendments to 35 Ill. Adm. 

Code 810. 811. and 814), R93-10 (Sept. 15, 1993), slip op. at 3-5 (adding required federal 

elements into existing State regulations); Safe Drinking Water Act Regulations, R88-26 (Aug. 9, 

1990), slip op. at 6-7 (retaining more stringent pre-existing State regulations within the body of 

new federal requirements). 

DISCUSSION 

The following discussion begins with substantive discussions of the four US EPA actions 

involved in this docket. A very brief discussion of the linlited Board-initiated corrections and 

clarifying amendments follows the discussion of USEPA actions. The discussion of USEPA 

actions is organized in chronological order. The discussions conclude with a description of the 

types of deviations that the Board makes from the literal text of federal regulations in adopting 

identical-in-substance rules. 

Discussion of the Particular Federal Actions Involved in This Docket 

New 2012 Primarv 24-Hour and Annual Average NAAQS for PM2.s-Section 243.120 

On January 15, 2013 (78 Fed. Reg. 3086), US EPA adopted new ambient air quality 

standards for fine patticulate matter as 40 C.F.R. 50.18. These are an annual average standard of 

12 micrograms per cubic meter (mg/m3

) and a 24-hour average standard of 35 mg/m3

. US EPA 

fiuther revised appendix N to 40 C.F.R. 50, which is entitled "Interpretation of the National 

Ambient Air Quality Standards for PM2.5." The Interpretation sets forth the data handling and 

computational requirements needed to demonstrate compliance with the PM2.s standards. 
8 

The addition of 40 C.F.R. 50.18 did not remove any of the existing particulate matter 

standards of 40 C.F.R. 50.6 (the 1987 primary and secondary 24-hour NAAQS for PM10), 50.7 

(the 1997 primary and secondary annual average and 24-hour NAAQS for PM2.5), or 50.13 (the 

2006 primary and secondary annual average and 24-hour NAAQS for PM25). Thus, the federal 

regulations now include one NAAQS for PM10,2 three annual average NAAQS for PM2.5, and 

three 24-hour NAAQS for PM25, as follows 

1987 Primary and Secondary 24-Hour NAAQS for PM10: 

150 >tg/m3, 24-hour average concentration 

1997 Primary and Secondary Annual Average NAAQS for PM2.5: 

15.0 >tg/m3

, annual arithmetic mean concentration, averaged over three years 

1997 Primary and Secondary 24-Hour NAAQS for PM2.5: 

65 >tg/m3

, 24-hour average concentration, 98th percentile, averaged over three 

years 

2006 Primary and Secondary Annual Average NAAQS for PM2.5: 

15.0 >tg/m3

, annual aritlunetic mean concentration, averaged over three years 

2006 Primary and Secondary 24-Hour NAAQS for PM2.5: 

35 >tg/m3, 24-hour average concentration, 98th percentile, averaged over three 

years 

2012 Primary Annual Average NAAQS for PM2.5: 

12.0 >tg/m3 annual arithmetic mean concentration, averaged over three years 

The 1987 NAAQS for PM10 is independent of the PM25 standards, as are the annual 

PM2.5 standards from the 24-hour standar-ds. Thus, after the 1997 institution of the PM2.5 

standards, the 2006 NAAQS revised the 24-hour standard downward, leaving the annual average 

standard unaffected. 3 The 2012 NAAQS has now revised the primary annual average standard 

downward, leaving the 1997 secondary annual average NAAQS and the 2006 primary and 

2 US EPA adopted 24-hour and annual average standards for PM10 in 1997 and 2006, but 

subsequently removed these standards. See 71 Fed. Reg. 61224 (Oct. 17, 2006) (removing the 

1987 annual average NAAQS for PM10); 69 Fed. Reg. 45592 (July 30, 2004) (removing the 1997 

primary and secondary annual average and 24-hour NAAQS for PM10); 62 Fed. Reg. 38652 (July 

18, 1997) (adopting the 1997 primary and secondary annual average and 24-hour NAAQS for 

PM2.s) 

3 US EPA did not revise the numerical standard, but did revise the data handling and calculations 

requirements in appendices D and N to 40 C.F.R. 50. See 71 Fed. Reg. 61144, 61165-66 (Oct. 

17, 2006). 
9 

secondary 24-hour NAAQS unchanged. 4 The US EPA PM NAAQS web page lists the following 

four NAAQS as the CU!Tent effective standards (even though all seven of the above PM NAAQS 

remain codified/: 

2012 Primary Annual Average NAAQS for PM2.5 

35 11g/m3 24-hour average concentration, 98th percentile, averaged over three 

years 

1997 Secondaty Annual Average NAAQS for PM2.5 

15.0 11g/m3

, annual arithmetic mean concentration, averaged over three years 

2006 Primmy and Secondary 24-Hour NAAQS for PM25 

35 11g/m3, 24-hour average concentration, 98th percentile, averaged over three 

years 

1987 Primary and Secondary 24-Hour NAAQS for PM10 

15 0 11g/m3

, 24-hour average concentration 

Any person interested in the substance of the 2012 primaty annual average and 24-hour 

NAAQS for PM2.5 should refer to the January 15,2015 Federal Register discussion that 

accompanied the USEPA amendments. Alternatively, interested persons could contact USEP A 

as directed in the Federal Register notice. 

The Board has incorporated the 2012 primary NAAQS for PM2.5 without substantive 

changes. Nevertheless, the Board has found a vety limited number of minor revisions to the 

federal text necessary. The primmy revisions involve ( I) codification of the 2012 standards as 

subsection (d) in Section 243.120, a centralized provision that includes all of the PM standards, 

rather than codification in a separate provision; (2) revising the language to the standardized 

nomenclature, "2012 primary annual average NAAQS for PM2.5"and "primary 24-hour NAAQS 

for PM2.5" in the text; and (3) updating the incorporation by reference to appendix N to 40 C.F.R. 

50, rather than amending substantive language, since the requirements of appendix N are 

incorporated by reference in the Illinois rules. All of those revisions are itemized and summarily 

outlined in Table I, which begins on page 17 of this opinion and order, and Table 2, which 

begins on page 18. No further discussion of those changes will appear in this opinion and order. 

4 Except as to revisions in the data handling and calculations requirements of appendix N to 40

Updated Edition of List of Designated Methods-Section 243.108 

On June 27,2013, US EPA released a new version of the List of Designated Methods. 

The List is not codified, and the Board did not see that USEP A published a notice for the update 

in the Federal Register. Rather, USEPA 's usual practice is simply to post a link to the updated 

version on the Intemet (at www. epa.gov/ttn/amtic!criteria.html). Thus, the Board found the 

update in a routine on-line check for an update. 

The updated version of the List included a number of methods that were modified since 

the last version dated December 17, 2012. The modified methods were the following, ananged 

by criteria pollutant:

module 801-00 I 000). 

The List of Designated Methods is essential to implementation of the various NAAQS. 

The List specifies the analytical methods that are permissible for the monitoring required to 

demonstrate compliance with ambient air quality standards. Thus, the modifications are 

important to any entity or State using the particular methods. 

Any person interested in the substance of the June 27, 2013 update to the List of 

Designated Methods should refer to that document. Alternatively, interested persons could 

contact USEPA as directed at www.epa.gov/ttn/amtic/criteria.html. 

The December 17, 2012 version of the List of Designated Methods is incorporated by 

reference in Section 243.108. The Board has updated that incorporation by reference to the June 

27, 2013 version of the List. In addition to updating the version of the List of Designated 

Methods, the Board has made two minor revisions to the existing text of the incorporation by 

reference. When adopting the incorporation by reference in National Ambient Air Quality 

Standards. US EPA Regulations (through December 31, 2012), Rl3- l l (July 25, 2013), the 

Board consistently added the definite article before each appearance of"List of Designated 

Methods" throughout the various substantive provisions at the request of JCAR. For the sake of 

consistency, the Board adds the definite article to "List of Designated Methods" in the 

incorporation by reference, which was overlooked in the prior rulemaking. The Board further 

changed "this document" to "the List of Designated Methods" in the appended Board note. 

These added revisions are itemized and summarily outlined in Table 2, which begins on 18 of 

this opinion and order. 

Request tor Public Comments: The Board requests comments on the update to the 

incorporation by reference to the June 27, 2013 version of the List of Designated Methods. 

New FRM for Lead-Section 243.108 

On July 3, 2013 (78 Fed. Reg. 40000), USEPA established a new federal reference 

method (FRM) for lead in total suspended pm1iculate matter (Pb-TSP). Establishing the new 
12 

FRM involved amendment of appendix G to 40 C.F.R. 50. The former FRM for Pb-TSP was a 

flame atomic absorption spectrographic (F AAS) method that originated with the 1978 NAAQS 

for lead. See 43 Fed. Reg. 46246 (Oct. 5, 1978). US EPA adopted a substantially more stringent 

NAAQS for lead in 2008, retaining use of the FRM adopted in 1978. See 73 Fed. Reg. 66964 

(Nov. 12, 2008). USEP A has now established a more technologically advanced, more precise, 

and more sensitive inductively coupled plasma-mass spectrometric (ICP-MS) method for lead 

analyses. The ICP-MS method was based on two methods fmmerly approved as federal 

equivalent methods (FEMs). 6 US EPA has now designated the former FRM as a FEM. 

Any person interested in the substance of the establishment of a new FRM for Pb-T SP 

and the designation of the fom1er FRM as an FEM for Pb-TSP should refer to the July 3, 2013 

Federal Register discussion that accompanied the USEPA amendments. Alternatively, 

interested persons could contact USEP A as directed in the Federal Register notice. 

The Board has decided to expedited consideration ofUSEPA's July 3, 2013 amendments 

in this docket, rather than wait until the as-yet-unreserved docket for the July l, 2013 through 

December 31, 2013 update period. The Board has multiple reasons for expedited consideration 

of the July 3, 2013 amendments: 

Expedited consideration will facilitate implementation of the July 3, 2013 

amendments, as well as the 2008 NAAQS for lead; 

Expedited consideration does not add substantially to the effort required to complete 

amendments based on the US EPA actions during the period January 1, 2013 through 

June 30, 2013, which underlie this proceeding; 

Expedited consideration will obviate very prompt initiation of any NAAQS update 

for the period July 1, 2013 through December 31. 2013 (to complete amendments 

before July 3, 2014); and 

Expedited consideration could obviate any NAAQS update for the period July 1, 

2013 through December 31. 2013 (assuming that USEPA does not again act prior to 

January 1, 2014 in any way that requires Board action). 

The Board incorporated the July 3, 2013 USEPA amendments without substantive 

changes. The Board updated the incorporation by reference to 40 C.F.R. 50 to the 2013 edition 

as amended at 78 Fed. Reg. 40000 (July 3, 2013). The Board found it necessary to depart from 

the literal USEP A text in doing so; the Board updated the incorporation by reference to appendix 

G to 40 C.F.R. 50, rather than amending substantive language, since the requirements of 

appendix G are incorporated by reference in the Illinois rules. This revisions is itemized and 

summarily outlined in Table 2, which begins on page 18 of this opinion and order. 

The Board further added the former F AAS FRM as an FEM. This required adding a 

6 See 78 Fed. Reg. at 40001 (identifYing methods EQL-0510-191 and EQL-0710-192); List of 

Designated Methods (December 17, 2012 or June 27, 2013 version), at p. 45. 
13 

reference to the USEP A designation of the former FRM as an FEM to the incorporation by 

reference to the List of Designated Methods. Since the former FRM was codified until 2013 as 

appendix G to 40 C.F.R. 50, the Board as a parenthetical reference to that version of appendix G. 

This revisions is itemized and summarily outlined in Table 2, which begins on page 18 of this 

opinion and order. 

Request (or Public Comments: The Board requests comments on the incorporation of 

the July 3, 2013 USEP A designation of a new FRM for Pb-TSP and designation of the former 

FRM as an FEM for Pb-TSP. 

Area Designations for the 2010 One-Hour NAAOS for Sulfur Oxides-Section 243.122 

On August 5, 2013 (78 Fed. Reg. 4 7191 ), USEP A amended various provisions in 40 

C.F .R. 81 to make area air quality designations for 29 areas in 16 states. 7 USEP A designated all 

of the affected areas as non-attainment for the 2010 primary one-hour NAAQS for sulfur oxides. 

Included were two areas in Illinois, as now codified in 40 C.F.R. 81.314 (see 78 Fed. Reg. at 

47199): 

Lemont: Cook County (Lemont Township) and 

Will County (DuPage and Lockport Townships); and 

Pekin: Tazewell County (Cincinnati and Pekin Townships) and 

Peoria County (Hollis Township). 

These area designations were based on ambient air quality monitoring data collected in 2009, 

2010, and 2011. 

The immediate importance to the State of Illinois of these non-attainment designations is 

that the State must undertake measures to submit a SIP that meets various federal requirements 

and provides for attainment of the 20 1 0 N AAQS for sulfur oxides. This submission must occur 

before April 6, 2015, and the SIP must provide for attainment no later than October 4, 2018. 78 

Fed. Reg. at 47193; see 42 U.S. C. 7502, 7514, 7514a (2011) (Clean Air Act non-attainmentprompted SIP requirements). 

The importance to the Board of these nonattainment designations is the effect that the 

area designations might have on the sunset provision in 40 C.F.R. 50.4( e) for the 1971 NAAQS 

for sulfur oxides. Section 243.122(a)(5) states that the Board will remove the 1971 NAAQS 

after the conditions in 40 C.F.R. 50.4(e) have been fulfilled. Further, the Board note attached to 

Section 243 .122(a)(5) includes explanation of the status of area designations for sulfur oxides, 

and USEPA's August 5, 2013 designations makes updating that explanation necessary. 

7 The states affected were Arizona, Florida, Illinois, Indiana, Iowa, Kentucky, Louisiana, 

Michigan, Missouri, Montana, New Hampshire, Ohio, Pennsylvania, Tennessee, West Virginia, 

and Wisconsin. 
14 

Any person interested in the substance of the designations of Pekin and Lemont as nonattainment for the 2010 NAAQS for sulfur oxides should refer to the July 3, 2013 Federal 

Register discussion that accompanied the USEP A amendments. Alternatively, interested persons 

could contact USEPA as directed in the Federal Register notice. The Board limits attention here 

to the effect those designations may have on the conditions recited in 40 C.F.R. 50.4(e) and on 

the language in the Board note appended to COITesponding Section 243.122(a)(5). 

The Board has decided to expedite consideration ofUSEPA's August 5, 2013 

amendments in this docket, rather than wait until the as-yet-unreserved docket for the July I, 

2013 through December 31, 2013 update period. The reasons for expedited consideration of the 

August 5, 2013 amendments are similar to those discussed above with regard to July 3, 2013 

designation of a new FRM: 

Expedited consideration will more promptly update the Board note appended to 

Section 243 .122(a)(5) more accurately infmm interested persons; 

Expedited consideration will not add substantial effort required to complete 

amendments based on the USEPA actions during the period January 1, 2013 through 

June 30, 2013; 

• Expedited consideration will obviate prompt initiation of any NAAQS update for the 

period July I, 2013 through December 31. 2013 (to complete amendments before 

August 5, 2014); and 

Expedited consideration could obviate any NAAQS update for the period July I, 

2013 through December 31. 2013 (assuming that USEPA does not again act prior to 

January 1, 2014 in any way that requires Board action). 

The Board has evaluated the effect of the August 5, 2013 USEPA area designations on 

Illinois ambient air quality standards. The present area designations do not yet fulfill the 

conditions of the sunset provisions in the sunset provision for the 1971 NAAQS for sulfur 

oxides. 

The sunset provision for the 1971 primary annual average and 24-hour NAAQS for sulfur 

oxides provides as follows: 

The [1971 primary annual average and 24-hourNAAQS for sulfur oxides] ... 

will remain applicable to all areas notwithstanding the promulgation of ... [the 

2010 primary one-hour NAAQS for sulfur oxides]. The [1971 primary annual 

average and 24-hour NAAQS for sulfur oxides] . .. will no longer apply to an 

area one year after the effective date of the designation of that area, pursuant to 

section I 07 of the Clean Air Act [( 42 U.S.C. § 740 I (2011))], for the ... [20 I 0 

primary one-hour NAAQS for sulfur oxides]; except that for areas designated 

nonattainment for the [ 1971 primary annual average and 24-hour NAAQS for 

sulfur oxides] ... as of the [August 23, 2010] effective date of ... [the 2010 

primary one-hour NAAQS for sulfur oxides], and areas not meeting the 
15 

requirements of a SIP call with respect to requirements for the ... [1971 primary 

annual average and 24-hour NAAQS for sulfur oxides], the [ 1971 primary annual 

average and 24-hour NAAQS for sulfur oxides] . .. will apply until that area 

submits, pursuant to section 191 of the Clean Air Act [(42 U.S.C. § 7514 

(20 I I))], and EPA approves, an implementation plan providing for attainment of 

the ... [2010 primmy one-hour NAAQS for sulfur oxides]. 40 C.F.R. 50.4(e) 

(20 13). 

Under this provision, the Board sees two thresholds for determining that the 1971 NAAQS for 

sulfbr oxides no longer applies to an area: 

I. Where the area is not designated non-attainment for the 1971 NAAQS, the 1971 

NAAQS will not apply one year after the effective date of USEP A designation of 

the attainment status of that area for the 2010 NAAQS. 

2. Where USEP A has designated the area non-attainment for the 1971 NAAQS 

before August 23, 2010, or a SIP call for the 1971 NAAQS has not been fulfilled 

for the area, the 1971 NAAQS will not apply after USEP A has approved an 

implementation plan (SIP or federal implementation plan) for the area for the 

2010 NAAQS. 

No area of Illinois was designated non-attainment for the 1971 NAAQS for sulfur oxides 

prior to August 23, 2010. See 40 C.F.R. 81.314 (20 II) (table for "Illinois-S02"). Thus, only 

the first threshold applies to areas in Illinois: the 1971 NAAQS will no longer apply to an area 

in Illinois one year after the effective date of a US EPA designation of the attainment status of 

that area for the 20 I 0 NAAQS for sulfur oxides. 

The August 5, 2013 designation of the Pekin and Lemont areas as non-attainment for the 

2010 NAAQS for sulfur oxides is effective October 4, 2013. See 78 Fed. Reg. at 47192. The 

1971 NAAQS for sulfur oxides will no longer apply to those areas after October 4, 2014. 

USEPA plans to complete the areas designations to include all areas in the future. See 78 Fed. 

Reg. at 47193-94. 

The August 5, 2013 area designation of two areas of the State is insufficient to prompt 

Board action to remove the 1971 NAAQS for sulfur oxides. The 1971 NAAQS will continue to 

apply to all other areas of the State that USEP A has not yet classified, notwithstanding 

inapplicability to Pekin and Lemont after October 4, 2014. 

The August 5, 2013 area designations for Pekin and Lemont prompt amendment of the 

Board note appended to Section 243.122(a)(5). When adopting the amendments in National 

Ambient Air Oualitv Standards. US EPA Regulations (through December 3 I. ?012), R l3-11 

(July 25, 2013), the Board added the Board note to explain the then-current status of fulfillment 

of the sunset conditions for the 1971 NAAQS for sulfur oxides. That explanation stated that 

USEPA had not yet made any area designations for the 2010 NAAQS. The explanation noted 

June 3, 2011 Agency recommendations to USEPA. The Board must now update the Board note 

explanation to reflect the August 5, 2013 area designations. The revisions to effect this update 
16 

itemized and summarily outlined in Table 2, which begins on page 18 of this opinion and order. 

Requests (or Public Comments: The Board requests comments on the effect of the 

August 5, 2013 USEP A area designations for the Pekin and Lemont areas for the 2010 primary 

one-hour NAAQS for sulfur oxides on the continued effectiveness of the 1971 annual average 

and 24-hour NAAQS for sulfur oxides. The Board requests comments on the revisions made to 

the Board note appended to Section 243.122(a)(5) in response to the August 5, 2013 area 

designations. 

Deviations from the Literal Text of the Federal Amendments 

and Non-Federallv Derived Corrections and Clarifications 

The Board routinely examines federal amendments and the base text of rules open for 

amendments to find any areas that need correction or clarification. JCAR and the Office of the 

Secretary of State also routinely examine the text and suggest corrections and clarifications. 

Sometimes suggestions arise from the Agency, US EPA, or members of the regulated 

community. The Board often makes revisions as a result. The revisions thus made are not 

directly derived from federal amendments. The Board is ever mindful of the limited discretion 

authorized in the context of an identical-in-substance proceeding. The Board is limited to "those 

changes that are necessaty for compliance with the Illinois Administrative Code," "technical 

changes that in no way change the scope or meaning of any portion of the regulations," and 

"apparent typographical and grammatical errors." See 415 ILCS 5/7.2(a) and (a)(7) (2012). 

Thus, the Board will only make minor, non-substantive corrections and clarifications in this 

context. These cmTections are non-substantive in effect. 

Tables follow that document the corrections and clarifications made in this proceeding. 

The first table lists the limited number of US EPA amendments that were not necessary in this 

proceeding. The second table itemizes the deviations from the literal text of the USEPA 

amendments involved in this proceeding. The third table lists the correction made in this docket 

that was not prompted by federal amendments. 

Tabulations of Deviations from the Literal Text of the Federal Amendments and 

Miscellaneous Board Housekeeping Amendments. 

The tables below list numerous corrections and amendments that are not based on current 

federal amendments. Table I (beginning immediately below) lists a number of federal 

amendments that the Board has not included in this docket. Table I gives a brief explanation 

why the Board has declined to make each. Table 2 (beginning immediately after Table I on page 

18) includes deviations made in this proposal for public comment from the verbatim text of the 

federal amendments. Table 3 (beginning immediately after Table 2 on page 21) contains 

corrections and clatifications that the Board made in the base text involved in this proposal. The 

amendments listed in Table 3 are not directly derived from the cutTen! federal amendments. 

Some of the entries in these tables are discussed further in appropriate segments of the general 

discussion beginning at page 7 of this opinion.

SUBPART B: STANDARDS AND MEASUREMENT METHODS 

Section 243.120 PM10 and PMz.s 

a) 1 987 Primary and Secondary 24-Hour NAAQS for PMw. 

I) The level of the 1 987 primary and secondary 24-hour NAAQS for PM10 is 

1 50 !J.g/m3, 24-hour average concentration. The 1 987 primary and 

secondary NAAQS for PM10 is attained when the expected number of 

days per calendar year with a 24-hour average concentration above 1 50 
28 

11g/m3

, as determined in accordance with appendix K to 40 CFR 50, 

incorporated by reference in Section 243.108, is equal to or less than one. 

2) This subsection (a)(2) co!Tesponds with 40 CFR 5 1.6(b), a provision 

marked "reserved" by USEP A. This statement maintains structural 

consistency with tbe co!Tesponding federal regulation. 

3) For the purpose of determining attainment of the 1 987 primary and 

secondary 24-hour NAAQS for PM10, particulate matter must be measured 

in the ambient air as PM10 by a method that fulfills either of the following 

requirements: 

A) An FRM based on appendix J to 40 CFR 50, incorporated 

by reference in Section 243. 1 08, and designated by US EPA 

and listed in List of Designated Methods, incorporated by 

reference in Section 243.108; or 

B) An FEM designated by USEP A and listed in List of Designated 

Methods, incorporated by reference in Section 243. 1 08. 

BOARD NOTE: This subsection (a) is derived from 40 CFR 50.6 (2012) 

(201 3). USEPA adopted 1 997 primary NAAQS for PM10 at 62 Fed. Reg. 38652 

(July 1 8, 1 997). As a result of a judicial vacatur, USEP A later removed the 

transitional provision relative to the 1 987 NAAQS at 65 Fed. Reg. 80776 (Dec. 

22, 2000) and the 1 997 NAAQS at 69 Fed. Reg. 45595 (July 30, 2004). Thus, the 

1987 primary and secondary NAAQS for PM10 are included in this subsection (a). 

b) 1 997 Primary and Secondary Annual Average and 24-Hour NAAQS for PM2.5• 

I) The 1 997 primary and secondary annual average NAAQS for PM2.s is 

1 5.0 11g/m3

, annual arithmetic mean concentration, and the 1 997 primary 

and secondary 24-hour NAAQS for PM2.5 is 65 11g/m3, 24-hour average 

concentration, measured in tbe ambient air as PM2.5 by a method that 

fulfills either of the following requirements: 

A) An FRM based on appendix L of 40 CFR 50, incorporated by 

reference in Section 243.108, and designated by USEPA and listed 

in the List of Designated Methods, incorporated by reference in 

Section 243.1 08; or 

B) An FEM designated by USEP A and listed in the List of Designated 

Methods, incorporated by reference in Section 243.108. 

2) The 1 997 primary and secondary annual average NAAQS for PM2_5 is met 

when the annual arithmetic mean concentration, as determined in 
29 

accordance with appendix N of 40 CFR 50, incorporated by reference in 

Section 243.108, is less than or equal to 1 5.0 11g/m3 

3) The 1 997 primary and secondary 24-hour NAAQS for PM1.5 is met when 

the 98th percentile 24-hour concentration, as dete1mined in accordance 

with appendix N of 40 CFR 50, incorporated by reference in Section 

243 .I 08, is less than or equal to 65 11g/m3. 

BOARD NOTE: This subsection (b) is derived from 40 CFR 50.7 (2Ql2) 

(201 3). The 2006 primmy and secondary annual average and 24-hour NAAQS 

for PM 25 differs from the 1 997 standards in that the 24-hour average 

concentration required by the 2006 standard is substantially lower (more 

stlingent) than that for the 1 997 standard. The Board has retained the 1 997 

standard in this subsection (b) because USEP A has retained the 1997 standard in 

40 CFR 50.6. 

c) 2006 Primary and Secondary Annual Average and 24-Hour NAAQS for PM2.5. 

I) The 2006 primary and secondary annual average NAAQS for PM2.5 is 

15.0 lJ.g/m3

, annual arithmetic mean concentration, and the 2006 primary 

and secondary 24-hour NAAQS for PM2.5 is 35 lJ.g/m3

, 24-hour average 

concentration, measured in the ambient air as PM2.5 by a method that 

fulfills either of the following requirements: 

A) An FRM based on appendix L of 40 CFR 50, incorporated by 

reference in Section 243. 1 08, and designated by USEPA and listed 

in the List of Designated Methods, incorporated by reference in 

Section 243.108; or 

B) An FEM designated by US EPA and listed in the List of Designated 

Methods, incorporated by reference in Section 243.108. 

2) The 2006 plimary and secondary annual average NAAQS for PM2.5 is met 

when the annual arithmetic mean concentration, as determined in 

accordance with appendix N of 40 CFR 50, incorporated by reference in 

Section 243.108, is less than or equal to 15.0 lJ.g/m3 

3) The 2006 primary and secondary 24-hour NAAQS for PM2.s is met when 

the 98th percentile 24-hour concentration, as determined in accordance 

with appendix N of 40 CFR 50, incorporated by reference in Section 

243 .I 08, is less than or equal to 3 5 11g/m3. 

BOARD NOTE: This subsection (c) is derived from 40 CFR 50.13 (2Ql2) 

(?0 13). 

d) 2012 Piimary Annual Average and 24-Hour NAAQS for PM>.s 
30 

I) The ?0 I? primarv annual average NAAQS for PM,5 is I? .0 ug/m3 annual 

mithmetic mean concentration. and the 2012 primary 24-hour NAAQS for 

PM,_5 is 35 ug/m3 ?4-hour average concentration. measured in the ambient 

air as PM,_5 bv a method that fulfills either of the following requirements: 

A) An FRM based on appendix L of 40 CFR 50. incomorated by 

reference in Section 243.108. and designated by USEPA and listed 

in List of Designated Methods. incomorated by reference in 

Section 243.1 08; or 

B) An FEM designated bv USEP A and listed in List of Designated 

Methods. incorporated by reference in Section ?43. 1 08. 

2) The 2012 mimarv annual NAAQS for PM,_5 is met when the annual 

arithmetic mean concentration. as detem1ined in accordance with appendix 

N of 40 CFR 50. incomorated by reference in Section 243.108. is less than 

or equal to 1 2.0 ug/m3

• 

3) The 2012 primary 24-hour NAAQS for PM, 5 is met when the 98th 

percentile 24-hour concentration. as determined in accordance with 

appendix N of 40 CFR 50. incorporated by reference in Section 243.108.

Section 243.122 Sulfur Oxides (Sulfur Dioxide) 

a) 1 971 Primary Annual Average and 24-Hour NAAQS for Sulfur Oxides (as Sulfur 

Dioxide (SOz)). 

I) The level of the 1971 primary annual average NAAQS for sulfur oxides is 

0.030 ppm, not to be exceeded in a calendar year. The annual arithmetic 

mean must be rounded to three decimal places (fractional parts equal to or 

greater than 0.0005 ppm must be rounded up). 

2) The level of the 1 97 1 primary 24-hour NAAQS for sulfur oxides is 0.14 

ppm, nQt to be exceeded more than once per calendar year. The 24-hour 

averages must be determined from successive non-overlapping 24-hour 

blocks starting at midnight each calendar day and must be rounded to two 

decimal places (fractional parts equal to or greater than 0.005 ppm must be 

rounded up). 
31 

3) Sulfur oxides must be measured in the ambient air as S02 by the FRM 

described in appendix A-2 to 40 CFR 50, incorporated by reference in 

Section 243.108, or by an FEM designated by USEPA and listed in the 

List of Designated Methods, incorporated by reference in Section 243.108. 

4) To demonstrate attainment, the annual arithmetic mean and the secondhighest 24-hour averages must be based upon hourly data that are at least 

75 percent complete in each calendar qumier. A 24-hour block average 

must be considered valid if at least 75 percent of the hourly averages for 

the 24-hour period are available. In the event that only 1 8-, 19-, 20-, 2 1-, 

22-, or 23-hour averages are available, the 24-hour block average must be 

computed as the sum of the available hourly averages using the number of 

hours (i.e., 1 8, 1 9, etc.) as the divisor. If less than 18-hour averages are 

available, but the 24-hour average would exceed the level of the standard 

when zeros are substituted for the missing values, subject to the rounding 

rule of subsection (b) of this Section, this must be considered a valid 24-

hour average. In this case, the 24-hour block average must be computed 

as the sum of the available hourly averages divided by 24. 

5) The 1971 primary annual average and 24-hour NAAQS for sulfur oxides 

set forth in this subsection (a) remains applicable to all areas 

notwithstanding the promulgation of the 20 I 0 primary one-hour NAAQS 

for sulfur oxides in subsection (c) of this Section. The Board will delete 

the 1 971 primary annual average and 24-hour NAAQS for sulfur oxides 

set forth in this subsection (a) after fulfillment of the conditions recited by 

USEPA in corresponding 40 CFR 50.4(e). 

BOARD NOTE: Corresponding 40 CFR 50.4(e) recites that the 1 971 

primary NAAQS for sulfur oxides remains effective in two types of areas 

for which USEP A has not yet approved an implementation plan for 

attainment with the 20 l 0 primary one-hour NAAQS for sulfur oxides. 

The first type of area is one that US EPA had designated as non-attainn1ent 

for that standard as of the effective date of the 2010 primary one-hour 

NAAQS for the 1 971 primary NAAQS for sulfur oxides as of the effective 

date of the 2010 NAAQS. That date was August 23, 2010. See 75 Fed. 

Reg. 35520 (June 22, 20 1 0). As of that date, USEP A had not designated 

any area in Illinois as non-attainment. See 40 CFR 81.314 (20 l 0). The 

Board is unaware of any US EPA SIP call for any area of Illinois relative 

to the 1 971 primary NAAQS for sulfur oxides. As efDee

eer 31, 2QP, 

US EPA B.aEl aet yet designated the attainment status of two areas in 

Illinois for the 2010 primarv one-hour NAAOS for sulfur oxides on 

August 5, 2013, effective October 4. ?013. See 40 CFR 81.314 (2Ql2) 

(2013), as amended at 78 Fed. Reg. 47 191 (Aug. 5. 20 1 3) (Lemont and

primary annual average and 24-hour NAAOS for sulfur oxides will no 

longer apply to those two designated areas effective October 4. 2014: 

although the NAAQS will continue to apply to all other areas of Illinois 

after that date. When the conditions of this subsection (a)(5) have been 

fulfilled as to all areas of Illinois, or USEP A has removed 40 CFR 50.4, 

the Board will remove the standard of this subsection (a) as obsolete. 

BOARD NOTE: This subsection (a) is derived from 40 CFR 50.4 (2Gl2). 

b) 1 971 Secondary Three-Hour NAAQS for Sulfur Oxides (as S02). 

1) The level of the 1 971 secondary three-hour NAAQS for sulfur oxides is 

0.5 ppm, not to be exceeded more than once per calendar year. The threehour averages must be determined from successive non-overlapping threehour blocks starting at midnight each calendar day and must be rounded to 

one decimal place (fractional pa1ts equal to or greater than 0.05 ppm must 

be rounded up). 

2) Sulfur oxides must be measured in the ambient air as S02 by the FRM 

described in appendix A-2 to 40 CFR 50, incorporated by reference in 

Section 243.108, or by an FEM designated by USEP A and listed in List of 

Designated Methods, incorporated by reference in Section 243.108. 

3) To demonstrate attainment, the second-highest three-hour average must be 

based upon hourly data that are at least 75 percent complete in each 

calendar quarter. A three-hour block average must be considered valid 

only if all three hourly averages for the three-hour period are available. If 

only one or two hourly averages are available, but the three-hour average 

would exceed the level of the standard when zeros are substituted for the 

missing values, subject to the rounding rule of subsection (b)(!) of this 

Section, this must be considered a valid tlu·ee-hour average. In all cases, 

the three-hour block average must be computed as the sum of the hourly 

averages divided by three. 

BOARD NOTE: This subsection (b) is derived from 40 CFR 50.5 (2GP). 

c) 2010 Pximary One-Hour NAAQS for Sulfur Oxides (as S02). 

I) The level of the 2010 primary one-hour NAAQS for sulfur oxides is 75 

ppb, measured in the ambient air as S02. 

2) The 20 I 0 one-hour primary NAAQS for sulfur oxides is met at an ambient 

air quality monitoxing site when the three-year average of the annual (99th 
33 

percentile) of the daily maximum one-hour average concentrations is less 

than or equal to 75 ppb, as determined in accordance with appendix T of 

40 CFR 50, incorporated by reference in Section 243.108. 

3) The level of the 20 l 0 one-hour primary NAAQS for sulfur oxides must be 

measured by an FRM based on appendix A-1 or A-2 of 40 CFR 50, 

incorporated by reference in Section 243.108, or by an FEM designated by 

US EPA and listed in List of Designated Methods, incorporated by 

reference in Section 243.108. 

BOARD NOTE: This subsection (c) is derived from 40 CFR 50.17 (2012). The 

1 971 primary NAAQS for S02 remains in effect until the federal conditions of 40 

CFR 50.4(e) have been fulfilled, as outlined in subsection (a)(5) of this Section 

and the appended Board note.

For the sake of expedience, the Hearing Officer encourages the pre-submission of 

testimony and exhibits, but will not require such pre-submission. Anv person wishing to 

submit oral testimonv, rather than pre-submitting testimonv for introduction into the 

record as though read, should notifv the Hearing Officer no later than October 24, 2013. 
HEARING OFFICER ORDER 

Scope of the Hearing1 

The Board reserved this docket pursuant to Sections 7.2 and 1 O(H) of the Environmental 

Protection Act (Act) (415 ILCS 517.2 and IO(H) (2012)) to update the Illinois ambient air quality 

regulations to include all cunent federal NAAQSs adopted and amended by the United States 

Environmental Protection Agency (USEP A) during the period January I, 2013 through June 30, 

2013. 

Section I O(H) mandates that the Board adopt ambient air quality standards that are identicalin-substance with National Ambient Air Quality Standards (NAAQS) adopted by USEP A pursuant 

to 42 U.S.C. § 7409 (2011). NAAQSs apply to ambient air, and each constitutes a detennination of 

the maximum level of a criteria pollutant that is allowable consistent with human health (a primmy 

standard) and public welfare (a secondmy standm·d). 42 U.S. C.§ 7409(b) (2011). As of June 30, 

2013, the federal regulations included 20 NAAQS for six criteria pollutants: carbon monoxide, 

lead nitrogen oxides, ozone, pmticulate matter, and sulfur oxides. See generally 40 C.F .R. 50 

(2013). USEPA has codified those NAAQS in 40 C.F.R. 50. 

This proceeding updates the Illinois mnbient air quality standards to accommodate 

amendments and other relevant USEP A actions with regard to NAAQS that occuned during the 

petiod Januaty I, 2013 through June 30, 2013. During this period, USEPA took the following 

actions: 

Januaty 15, 2013 (78 Fed. Reg. 3086): USEPA adopted the new 2012 ptimat·y 24-hour 

and annual average NAAQS for PM2.5• USEPA further revised the intetpretation of the 

NAAQS for PM2.s· 

June 27, 2013: USEPA updated the "List of Designated Reference and Equivalent 

Methods." 

Since June 30, 2013, USEPA took two more actions that the Board detetmined to include in 

this proceeding. The later actions are the following: 

July 3, 2013 (78 Fed. Reg. 40000): USEPA established a new FRM for measuring lead 

in total suspended patiiculate matter for the pmposes of the lead NAAQS. 

August 5, 2013 (78 Fed. Reg. 47191): USEPA made area designations for the 2010 

NAAQS for sulfur dioxide. 

1 The Board does not usually hold public hearings on identical-in-substance rules. This hearing 

is held as required by Section 110 of the federal Clean Air Act (42 U.S.C. § 7410 (2011)), 

because this proceeding would entail a SIP revision. 
Sections 7.2 and !O(H) of the Act (415 ILCS 5/7.2 and IO(H) (2012)) provide the Board 

little discretion but to adopt amendments that are identical-in-substance to the federal NAAQS. 

Section I O(H) states in pe1tinent part as follows: 

In accordance with subsection (b) of Section 7 .2, the Board shall adopt ambient 

air quality standards specifying the maximum pennissible shmt-tenn and longtelm concentrations of various contaminants in the atmosphere; those standards 

shall be identical in substance to the national ambient air quality standards 

promulgated by the Administrator of the United States Enviromnental Protection 

Agency in accordance with Section I 09 of the Clean Air Act. 415 ILCS 511 O(H) 

(2012). 

Section 7.2 adds the following limitations relative to the scope of the Board's discretion: 

In the context of a mandate that the Board adopt regulations to secure federal 

authorization of a program, regulations that are "identical in substance" means State 

regulations which require the same actions with respect to protection of the 

enviromnent, by the same group of affected persons, as would federal regulations if 

USEP A administered the subject program in illinois .... [T]he Board shall adopt 

the verbatim text of such USEP A regulations as are necessary and appropriate for 

authorization of the program. In adopting "identical in substance" regulations, the 

only changes that may be made by the Board to the federal regulations are those 

changes that are necessmy for compliance with the Illinois Administrative Code, and 

technical changes that in no way change the scope or meaning of any pmtion of the 

regulations. 415 ILCS 5/7.2 (2012). 

For these reasons, the Bom·d lacks the discretion to address the technical me1its of any of the 

federal NAAQSs involved in this proceeding. The Board has discretion only how best to 

incorporate the NAAQSs into the illinois an1bient air quality regulations. 

Notice and Service Lists 

Pursuant to 35 Ill. Adm. Code 102.422, a notice and service list will be established. 

Persons on the notice list will receive notice of all Board actions and Hem·ing Officer orders. 35 

Ill. Adm. Code 102.422(a). In compalison, Section 102.422(b) states in part: 

The hea1ing officer may establish a service list for any regulatory proceeding, in 

addition to the notice list. The hearing officer may direct participants to serve 

copies of all documents upon the persons listed on the service list. 35 Ill. Adm. 

Code I 02.422(b ). 

Persons on the service list will receive notice of Board actions and Hearing Officer 

orders, as well as testin1ony and filings in the proceeding. The service list is reserved for persons 

who will be testifYing and participating in the mlemaking. With the development of the Board's 

website (www.ipcb.state.il.us), COOL system and electronic filing, all prefiled testin1ony, public 

comments, and other filings will be available for viewing and downloading expeditiously. The 
only exception will be voluminous filings, which will be available on request. Furthe1more, with 

the development of COOL, persons not on the service list, who wish to file a public comment 

and only a public conm1ent, need not serve their comments on the service list in this proceeding.

2) This subsection ( a)(2) corresponds with 40 CFR 51.6(b ), a provision 

marked "reserved" by US EPA. This statement maintains structural 

consistency with the corresponding federal regulation. 

3) For the purpose of determining attai!m1ent of the 1987 primary and 

secondary 24-hour NAAQS for PM10, particulate matter must be measured 

in the ambient air as PMw by a method that fulfills either of the following 

requirements:

Methods, incorporated by reference in Section243 .1 08. 

BOARD NOTE: This subsection (a) is derived from 40 CFR 50.6 (2012) 

(2013). USEPA adopted 1997 primaryNAAQS for PM10 at 62 Fed. Reg. 38652 

(July 18, 1997). As a result of a judicial vacatur, USEPA later removed the 

transitional provision relative to the 1987 NAAQS at 65 Fed. Reg. 80776 (Dec. 

22, 2000) and the 1997 NAAQS at 69 Fed. Reg. 45595 (July 30, 2004). Tims, the 

1987 primary and secondary NAAQS for PM10 are included in this subsection (a).

BOARD NOTE: This subsection (b) is derived from 40 CFR 50.7 (2012) 

{2013). The 2006 primary and secondary annual average and 24-hour NAA.QS 

for PM 2.5 differs from the 1997 standards in that the 24-llOur average 

concentration required by the 2006 standard is substantially lower (more 

stringent) than that for the 1997 standard. The Board has retained the 1997 

standard in this subsection (b) because USEPA has retained the 1997 standard in

Section 243.122 Sulfur Oxides (Sulfur Dioxide) 

a) 1971 Primary Almual Average and 24-HourNAAQS for Sulfur Oxides (as Sulfur 

Dioxide (S02)). 

1) The level of the 1971 primary annual average NAAQS for sulfur oxides is 

0.030 ppm, not to be exceeded in a calendar year. The annual arithmetic 

mean must be rounded to three decimal places (fractional parts equal to or 

greater than 0.0005 ppm must be rounded up). 

2) The level of the 1971 primary 24-hour NAAQS for sulfur oxides is 0.14 

ppm, not to be exceeded more than once per calendar year. The 24-hour 

averages must be determined from successive non-overlapping 24-hour 

blocks slatting at midnight each calendar day and must be rounded to two 

decimal places (fractional parts equal to or greater than 0.005 ppm must be 

rounded up). 

3) Sulfur oxides must be measured in the ambient air as S02 by the FRM 

described in appendix A-2 to 40 CFR 50, incorporated by reference in 

Section 243.108, or by an FEM desigoated by USEP A and listed in the 

List of Designated Methods, incorporated by reference in Section 243.108. 

4) To demonstrate attainment, the annual arithmetic mean and the secondhighest 24-hour averages must be based upon hourly data tbat are at least 

75 percent complete in each calendar quarter. A 24-hour block average 

must be considered valid if at least 75 percent of the hourly averages for 

the 24-hour period are available. In the event that only 18-, 19-,20-,21-, 

22-, or 23-hour averages are avaihible, the 24-hour block average must be 

computed as the sum of the available hourly averages using the number of 

hours (i.e., 18, 19, etc.) as the divisor. Ifless than 18-hour averages are 

available, but the 24-hour average would exceed the level of the standard 

when zeros are substituted for the missing values, subject to the rounding 

rule of subsection (b) of this Section, this must be considered a valid 24-

hour average. In this case, the 24-hour block average must be computed 

as the sum of the available hourly averages divided by 24. 

5) The 1971 primary annual average and 24-hour NAAQS for sulfur oxides 

set forth in tlris subsection (a) remains applicable to all areas 

notwithstanding the promulgation of the 2010 primary one-hour NAAQS 

for sulfur oxides in subsection (c) of this Section. The Board will delete

the 1971 primary annual average and 24-hour NAAQS for sulfur oxides 

set forth in this subsection (a) after fulfillment of the conditions recited by 

US EPA in corresponding 40 CFR 50.4(e). 

BOARD NOTE: Corresponding 40 CFR 50.4(e) recites that the 1971 

primary NAAQS for sulfur oxides remains effective in two types of areas 

for which USEPA has not yet approved an implementation plan for 

attainment with the 2010 primary one-hour NAAQS for sulfur oxides. 

The first type of area is one that US EPA had designated as non-attainment 

for that standard as of the effective date of the 2010 primary one-hour 

NAAQS for the 1971 primary NAAQS for sulfur oxides as of the effective 

date ofthe2010 NAAQS. That date was Augnst 23,2010. See 75 Fed. 

Reg. 35520 (June 22, 201 0). As of that date, US EPA had not designated 

any area in Illinois as non-attainment. See 40 CFR 81.314 (2010). The 

Board is unaware of any US EPA SIP call for any area of Illinois relative 

to the 1971 primaryNAAQS for sulfur oxides. As ofDeeem!Jer 31, 2().l.;l, 

USEP A had net yet designated the attainment status of two areas in 

Illinois for the 2010 primary one-hour NAAOS for sulfur oxides on 

August 5. 2013. effective October 4. 2013. See 40 CFR 81.314 (2Gl2) 

(2013). as amended at 78 Fed. Reg. 47191 (Aug. 5. 2013) (Lemont and 

Pekin areas). The Agency recommended that USEPA desigaate limited 

areas of Illinois as non attainment with fue 2010 primary one hour 

NAAQS. See letter of June 2, 2011 from Laurel Kreack, Chief, Bureau of 

Air, Ageney,te-C-heryl A. Newton, Director, Office efthe Air and 

Radiation Division, USEPA Region 5 (available at http://W'<I".V.epa.gev/ 

se2desigaations/reoletters/R5 _IL _ree::wtechanalysis.pdt). The 1971 

primarv annual average and 24-hour NAAOS for sulfur oxides will no 

longer apply to those two designated areas effective October 4. 2014: 

although the NAAQS will continue to applv to all other areas of Illinois 

after that date. When the conditions of this subsection (a)(5) have been 

fulfilled as to all areas of Illinois, or USEPA has removed 40 CFR 50.4, 

the Board will remove the standard of tlris subsection (a) as obsolete. 

BOARD NOTE: Tlris subsection (a) is derived from 40 CFR 50.1 (2012). 

b) 1971 Secondary Three-Hour NAAQS for Sulfirr Oxides (as S02). 

1) The level of the 1971 secondary three-hour NAAQS for sulfur oxides is 

0.5 ppm, not to be exceeded more than once per calendar year. The threehour averages must be determined from successive non-overlapping three-

NOTICE OF PROPOSED AMENDMENTS 

hour blocks starting at midnight each calendar day and must be rounded to 

one decimal place (fractional parts equal to or greater than 0.05 ppm must 

be rounded up). 

2) Sulfur oxides must be measured in the ambient air as S02 by the FRM 

described in appendix A-2 to 40 CFR 50, incorporated by reference in 

Section 243.108, or by an FEM designated by USEP A and listed in List of 

Designated Methods, incorporated by reference in Section 243.108. 

3) To demonstrate attainment, the second-highest three-hour average must be 

based upon hourly data that are at least 75 percent complete in each 

calendar quarter. A three-hour block average must be considered valid 

only if all three hourly averages for the three-hour peliod are available. If 

only one or two hourly averages are available, but the three-hour average 

would exceed the level of the standard when zeros are substituted for the 

missing values, subject to the rounding rule of subsection (b)( 1) of this 

Section, this must be considered a valid three-hour average. In all cases, 

the three-hour block average must be computed as the sum of the hourly 

averages divided by three. 

BOARD NOTE: This subsection (b) is derived from 40 CFR 50.5~. 

c) 2010 Primary One-Hour NAAQS for Sulfur Oxides (as S02). 

1) The level of the 2010 primary one-hour NAAQS for sulfur oxides is 75 

ppb, measured in the ambient air as S02. 

2) The 2010 one-hour primary NAAQS for sulfur oxides is met at an ambient 

air quality monitoring site when the three-year average of the armual (99th 

percentile) of the daily maximum one-hour average concentrations is Jess 

than or equal to 7 5 ppb, as determined in accordance with appendix T of 

40 CFR 50, incorporated by reference in Section 243.108. 

3) The level of the 2010 one-hour primary NAAQS for sulfur oxides must be 

measured by an FRMbased on appendixA-1 or A-2 of40 CFR50, 

incorporated by reference in Section 243.108, or by an FEM designated by 

USEP A and listed in List of Designated Methods, incorporated by 

reference in Section243.108.

general schedule in this table applies for all other purposes, most notably, for data that USEPA 

will use forredesignations to attainment. Corresponding table 1 to 40 CFR 50.14(c)(2) cites the 

2010 one hour l>lAAQS for nitrogen oxides as "80 100 PPB, final level TBD" and !Jre 2010 one

Notice of Public Comment Period and Public Hearing 

for State Implementation Plan (SIP) Submittals 

for National Ambient Air Quality Standards (NAAQS) 

The Pollution Control Board (Board) is accepting public comments and will conduct a public 

hearing on a prospective NAAQS SIP submittal to the U.S. Environmental Protection Agency 

(USEPA). The Board will accept written comments on the proposed rule that will form the basis 

for the SIP proposal until 45 days after the date of this issue of the Il

inois Register, and a public 

hearing will occur in Springfield and Chicago on October 31, 2013. The Board presently 

anticipates adoption of new exemptions from the definition of volatile organic material (VOM) 

on November 21, 2013, or within a short time after that date. 

Section 1 O(H) of the Environmental Protection Act (Act) [ 415 ILCS 511 O(H)] requires the Board 

to do as follows: 

[T]he Board shall adopt ambient air quality standards specifying the maximum 

permissible short-term and long-term concentrations of various contaminants in 

the atmosphere, those standards shall be identical in substance to the national 

ambient air quality standards promulgated by the Administrator of the United 

States Environmental Protection Agency in accordance with Section 10 9 of the 

Clean Air Act [(42 U.S.C . § 7409 ( 2011))]. 

The USEPA NAAQS are codified at 40 C.F.R. § 50. The Board is required to adopt those 

exemptions using the "identical in substance" rulemaking procedure of Section 7.2 of the Act 

[415 ILCS 5/7. 2]. The Illinois listing of these compounds is codified at 35 Ill. Adm. Code 243. 

On September 5, 2013, the Board adopted a proposal for public comment in docket Rl4-6 to 

initiate adoption of the latest USEP A amendments to and actions affecting the federal NAAQS 

during the period January 1, 2013 through June 30,2013, adding later USEPA amendments of 

July 3, 2013 and August 5, 2013. 

• On January 15, 2013 (7 8 Fed. Reg. 3086), USEPA adopted new primary annual 

average and 24-hour NAAQS for :fine particulate matter (PM25). 

• USEPA issued a revised version of the "List of Designated Reference and Equivalent 

Methods"(List of Designated Methods) on June 27, 2013.

OPINION AND ORDER OF THE BOARD (by J.A. Burke): 

This rulemaking updates the ambient air quality standards in the Board's air pollution 

regulations (35 Ill. Adm. Code 243) to include revisions to the National Ambient Air Quality 

Standards (NAAQS)1 adopted by the United States Enviromnental Protection Agency (US EPA) 

pursuant to section 1 09 of the Clean Air Act (CAA) (42 U.S.C. § 7409 (201 1)) during the period 

Janumy I, 2013 through June 30, 2013 and on July 3, 2013 and August 5, 2013. Today's action 

adopts the first update to the initial amendments undertaken by the Board to fulfill a new 

identical-in-substance mandate adopted in P.A. 97-945 (eff. Aug. 1 0, 201 2) to ensure that 

Illinois' regulations reflect USEPA's most recent NAAQS. The Board adopted the initial 

amendments in National Ambient Air Quality Standards. USEPA Regulations (through 

December 31. 2012), Rl3-ll (July 25, 2013), which were effective on July 29, 2013. See 37 Ill. 

Reg. 12882 (Aug. 9, 2013). 

Today the Board adopts amendments to segments of the Illinois mnbient air quality 

standards to reflect revisions and US EPA actions that affect the federal NAAQS codified in 40 

C.F.R. 50. As explained below, the Board intends the Illinois ambient air quality standards 

adopted in this proceeding to be identical-in-substance with their federal counterpmts, as 

"identical-in-substance" is defined by Section 7.2(a) of the Enviromnental Protection Act (Act) 

(415 ILCS 5/7.2(a) (2012)). 

Section !O(H) of the Act (415 ILCS 5/IO(H), as added by P.A. 97-945 (eff. Aug. 1 0, 

2012)), mandates this rulemaking requiring the Board to "adopt ambient air quality standards 

specifying the maximum pennissible shmt-te1m and long-te1m concentrations of various 

contan1inants in the atmosphere; those standards shall be identical in substance to the national 

mnbient air quality standards promulgated by ... the United States Environmental Protection 

Agency in accordance with Section 1 09 of the Clean Air Act [(42 U.S.C. § 7409)]." 415 ILCS 

5/IO(H). In addition, Section 9.1 (e) of the Act requires the Board to conduct this rulemaking 

pursuant to Section 7.2(b) of the Act (415 ILCS 5/7.2(b) (2012)) for adopting mles that are 

"identical in substance" to the federal requirements. 

Section !O(H) of the Act (415 ILCS 5/IO(H) (2012)) and Section l -5(c)(l) of the 

Administrative Procedure Act (APA) (5 ILCS 1 00/5-l -5(c)(l) (2012)) also provide that Title VII 

1 Throughout this opinion and in the regulatory text, the Board uses the abbreviation "NAAQS" 

to refer to a single standard and "NAAQS" to refer to multiple standards. 
(' I 

2 

of the Act and Section 5-35 of the APA (5 ILCS I 00/5-35 (2012)) do not apply to this 

proceeding. ·Accordingly, the Board did not adopt a "First Notice" proposal, or a "Second 

Notice" proposal for review by the Joint Committee on Administrative Rules (JCAR). However, 

as provided in Section l O(H) of the Act, and as explained in the two following segments of this 

opinion and order, the Board, did provide notice of the mlemaking proposal in the Illinois 

Register before adopting the amendments, held one public hearing on the proposal as required by 

the federal Clean Air Act (33 U.S.C. § 741 O(a) (20 11 )), and allowed for public comment. 

The Board reserved this docket to accommodate amendments that are necessary to update 

the Illinois ambient air quality standards to reflect revisions and USEP A actions that affect the 

federal NAAQS during the period January 1, 2013 tln·ough June 30, 2013. For reasons explained 

below, the Board has included amendments to accommodate USEP A actions that occmTed on 

July 3, 2013 and August 5, 2013. Board action is necessary to amend the Illinois ambient air 

quality standards to confonn with the NAAQS adopted and amended by USEP A. 

PUBLIC COMMENTS 

The Board adopted a proposal for public comment in tins proceeding on September 5, 

2013. A Notice of Proposed Amendments appeared in the September 20,2013 issue of the 

Illinois Register, at 37111. Reg. 15314. The Board held a public hearing in this matter on 

October 31,2013 and received public comment on the proposal until November 4, 2013 (45 days 

after the date of Illinois Register publication. 

Agency personnel attended the public hearing, but did not present testimony or 

comments. The Illinois Envit·onn1ental Regulatory Group (!ERG) subnlitted a public comment 

in supp011 of adoption of the amendments as proposed. That comment is described as follows:

The Board also received a document from JCAR that indicates a lin1ited number of 

revisions that JCAR has suggested in the text. The Board has revised the text in response to 

some of the JCAR suggestions and has declined to follow others. Table 4 below (beginning on 

page 21) indicates the suggestions that the Board has followed. Table 5 (begimling on page 22) 

explains the suggestions that the Board has declined. 

FEDERALLY REQUIRED PUBLIC HEARING 

The Board expects that the Illinois Environmental Protection Agency (Agency) will 

submit the present amendments as a revision to the Illinois State Implementation Plan (SIP) for 

various contaminants pursuant to section 110 of the federal Clean Air Act (42 U.S.C. § 7410(a) 

(2011) and the implementing USEPA regulations. See 40 C.P.R. 51.102 and appendix V (2012). 

As authorized by 415 ILCS 5/9.1(e), the Board held a public hearing on October 31, 

2013. This was to allow interested members of the public to conunent on the proposed 

amendments and the anticipated SIP revision that will result from their adoption. The Board 

simultaneously conducted the hearing via teleconference at Chicago and Springfield, so that 

persons at both locations may freely pm1icipate in the proceedings.

The record does not include a copy of the following documents, which are all otherwise 

publicly available: 

• The Federal Register notice relating to this action (referenced elsewhere in this opinion 

and order); 

• Federal statutes and regulations referenced in this opinion and order; and 

• Illinois statutes and regulations referenced in this opinion and order. 

OVERVIEW OF THE FEDERAL NAAOS AND THIS PROCEEDING 

The amendments adopted today are intended to make the Illinois ambient air quality 

standards identical-in-substance to the NAAQS adopted by USEPA. Today's adopted 

amendments include US EPA revisions and ancillary actions, such as USEP A approvals of 

reference methods and equivalent methods, during the peliod January 1, 2013 through June 30, 

2013. The Board included later federal actions that occmred on July 3, 2013 and August 5, 

2013, as described below. 

Docket R14-6: Januarv 1. 2013 through June 30, 2013 Amendments 

USEPA amended the federal NAAQS once during the petiod January 1, 2013 through 

June 30, 2013. In addition to the amendments to the NAAQS, US EPA updated the document 

"List of Designated Reference and Equivalent Methods" (List of Designated Methods) on June 

27, 2013. The List of Designated Methods is essential to implementation of the NAAQS. Board 

action is required on both USEP A actions, as is summarized below: 

Januarv 15, 2013 (78 Fed. Reg. 3086): Adoption of new 2012 Primarv 24-Hour and 

Annual Average NAAOS for PM,,5 

Description of the USEPA action: USEPA adopted the new 2012 primary 24-

hour and annual average NAAQS for PM25. USEPA further revised the 

interpretation of the NAAQS for PM2.5. 

Prospective necessary Board action in response: The Board must incorporate the 

new NAAQS and revised interpretation into 35 Ill. Adm. Code 243. 

Jnne 27,2013: Update to the List of Designated Methods 

Description of the USEPA action: US EPA updated the "List of Designated 

Reference and Equivalent Methods." 

Prospective necessary Board action in response: The Board must update the 

incorporation by reference to this new version of the List. 
4 

Later USEPA NAAQS-Related Actions oflnterest 

The Board engages in ongoing monitoring of federal actions. As of the date of this 

opinion and accompanying order, the Board has identified two USEPA actions since June 30, 

2013 that further affected the NAAQS in a way that would require Board attention. The Board 

believes that expedited consideration of these USEP A actions would confer two benefits: ( 1) 

expedited consideration could aid implementation of the Illinois ambient air quality standards; 

(2) expedited consideration could obviate action in the next NAAQS update for the period July I, 

2013 tlu·ough December 31, 2013. The two later USEPA actions are the following: 

Julv 3, 2013 (78 Fed. Reg. 40000): New FRM for Lead in Total Suspended 

Particulate Matter 

Description of the USEPA action: USEPA amended appendix G to 40 C.F.R. 50 

to establish a new FRM for measuring lead in total suspended particulate matter 

for the purposes of the lead NAAQS. 

Prospective necessary Board action in response: The Board should update the 

incorporation by reference to appendix G in Section 243.108 by adding a Federal 

Register citation to this action to incorporate the changes into the Illinois 

regulations. 

August 5, 2013 (78 Fed. Reg. 47191): Area Designations for Two Areas in Illinois 

Under the 2010 Primarv Annual Average and 24-Hour NAAQS for Sulfur 

Oxides 

Description of the USEPA action: USEPA made area designations for the 2010 

NAAQS for sulfur dioxide. 

Prospective necessary Board action in response: The Board should outline that 

this action does not impact the continued viability of the 1971 annual average and 

24-hour primary NAAQS for sulfur oxides. The Board must modify the Board 

note appended to 35 Ill. Adm. Code 243.122(a)(5), which states that USEPA has 

not designated areas for the 2010 NAAQS and mentions a 2011 Agency 

recommendation for area designations. 

Summarv Listing of the Federal Actions 

Upon Which Action is Required in This Docket 

Based on the foregoing, the two federal actions that fmm the basis for Board action in 

this update docket are the following, listed in cln·onological order:

The Context of This Identical-in-Substance Proceeding 

The Board does not engage in substantive review of federal standards in the context of an 

identical-in-substance proceeding. Rather, the Board reviews federal standards only to the extent 

necessmy to make a "best fit" for those standards in the context of the Illinois regulatory scheme. 

The Board tries to follow the structure and content of federal regulations where possible. 

This ensures the full incorporation of all necessm·y elements of the present federal standards, and 

it makes updating the regulations easier when future federal amendments occur. 

Depmtures from the federal structure may occur for a vmiety of reasons and will be noted 

as needed below. Where more sttingent pre-existing State standards exist that will continue in 

effect after incorporation of federal elements, the Board will incmporate a structure that retains 

those State standards. See, e.g., RCRA Subtitle D Amendments (Amendments to 35 Ill. Adm. 

Code 810. 811. and 814), R93-10 (Sept. 15, 1993), slip op. at 3-5 (adding required federal 

elements into existing State regulations); Safe Drinking Water Act Regulations, R88-26 (Aug. 9, 

1990), slip op. at 6-7 (retaining more stringent pre-existing State regulations within the body of 

new federal requirements). 

DISCUSSION 

The following discussion begins with substantive discussions of the four USEPA actions 

involved in this docket. A very brief discussion of tl1e limited Board-initiated corrections and 

clarifying amendments follows the discussion of USEPA actions. The discussion of USEPA 

actions is organized in chronological order. The discussions conclude with a description of the 

types of deviations that the Board makes from the literal text of federal regulations in adopting 

identical-in-substance rules. 

Discussion of the Particular Federal Actions Involved in This Docket 

New 2012 Primarv 24-Hour and Annual Average NAAQS for PM2.,-Section 243.120 

On Janumy 15, 2013 (78 Fed. Reg. 3086), USEPA adopted new ambient air quality 

standards for fine particulate matter as 40 C.F.R. 50.18. These are an annual average standard of 

12 micrograms per cubic meter (mg/m3) and a 24-hour average standard of 35 mg/m3 USEP A 

further revised appendix N to 40 C.F.R. 50, which is entitled "Interpretation of the National 
6 

Ambient Air Quality Standards for PM2.5." The Intetpretation sets fmih the data handling and 

computational requirements needed to demonstrate compliance with the PM2.s standards. 

The addition of 40 C.F.R. 50.18 did not remove any of the existing patiiculate matter 

standards of 40 C.F.R. 50.6 (the 1987 primary and secondary 24-hour NAAQS for PM10), 50.7 

(the 1997 primary and secondary annual average and 24-hour NAAQS for PM2.5), or 50.13 (the 

2006 primmy and secondary annual average and 24-hour NAAQS for PM25). Thus, the federal 

regulations now include one NAAQS for PM10,

2 three annual average NAAQS for PM2.5, and 

three 24-hour NAAQS for PM2.s, as follows 

1987 Primary and Secondary 24-,Hour NAAQS for PM10: 

150 11g/m3, 24-hour average concentration 

1997 Primary and Secondary Annual Average NAAQS for PM2.5: 

15.0 11g/m3, annual arithmetic mean concentration, averaged over three years 

1997 Primary and Secondary 24-Hour NAAQS for PMz.5: 

65 11g/m3, 24-hour average concentration, 98th percentile, averaged over tlu·ee 

years 

2006 Primary and Secondary Annual Average NAAQS for PM2.s: 

15.0 11g/m3

, annual aritlunetic mean concentration, averaged over three yem·s 

2006 Primmy and Secondary 24-Hour NAAQS for PM25: 

35 11g/m3

, 24-hour average concentration, 98th percentile, averaged over tlu·ee 

years 

2012 Primary Annual Average NAAQS for PM25: 

12.0 11g/m3 annual aritlunetic mean concentration, averaged over three years 

The 1987 NAAQS for PM10 is independent of the PM2.5 standards, as are the annual 

PMz.s standards from the 24-hour standards. Thus, after the 1997 institution of the PM2.s 

standards, the 2006 NAAQS revised the 24-hour standard downward, leaving the annual average 

standard unaffected. 3 The 2012 NAAQS has now revised the primary atmual average standard 

downward, leaving the 1997 secondary annual average NAAQS and the 2006 primary and 

2 USEPA adopted 24-hour and annual average standards for PM10 in 1997 and 2006, but 

subsequently removed these standards. See 71 Fed. Reg. 61224 (Oct. 17, 2006) (removing the 

1987 annual average NAAQS for PM10); 69 Fed. Reg. 45592 (July 30, 2004) (removing the 1997 

primary and secondary annual average and 24-hour NAAQS for PM10); 62 Fed. Reg. 38652 (July 

18, 1997) (adopting the 1997 primary and secondaty annual average and 24-hour NAAQS for 

PMz.s) 

3 USEP A did not revise the numerical standard, but did revise the data handling and calculations 

requirements in appendices D and N to 40 C.F.R. 50. See 71 Fed. Reg. 61144, 61165-66 (Oct. 

17, 2006). 
7 

secondary 24-hour NAAQS unchanged. 4 The US EPA PM NAAQS webpage lists the following 

four NAAQS as the current effective standards (even though all seven of the above PM NAAQS 

remain codified)5: 

2012 Primary Annual Average NAAQS for PM25 

35 [.tg/m3 24-hour average concentration, 98th percentile, averaged over three 

years 

1997 Secondmy Annual Average NAAQS fm: PM2.5 

15.0 [.tg/m3

, annual arithmetic mean concentration, averaged over three years 

2006 Primmy and Secondmy 24-Hour NAAQS for PM2.5 

35 [.tg/m3, 24-hour average concentration, 98th percentile, averaged over three 

years 

1987 Primary and Secondary 24-Hour NAAQS for PM10 

15 0 [.tg/m3, 24-hom average concentration 

Any person interested in the substance of the 2012 primmy annual average and 24-hour 

NAAQS for PM2.5 should refer to the Janumy 15, 2015 Federal Register discussion that 

accompanied the USEP A amendments. Altematively, interested persons could contact USEP A 

as directed in the Federal Register notice. 

The Board has incorporated the 2012 primary NAAQS for PM2.5 without substantive 

changes. Nevertheless, the Board has found a ve1y limited number of minor revisions to the 

federal text necessary. The primmy revisions involve ( I) codification of the 2012 standards as 

subsection (d) in Section 243.120, a centralized provision that includes all of the PM standards, 

rather than codification in a separate provision; (2) revising the language to the standardized 

nomenclature, "2012 primmy annual average NAAQS for PM2.5"and "primmy 24-hom NAAQS 

for PM2.s'' in the text; and (3) updating the incorporation by reference to appendix N to 40 C.F.R. 

50, rather than aJnending substantive language, since the requirements of appendix N are 

incorporated by reference in the Illinois mles. All of those revisions are itemized and summarily 

outlined in Table I, which begins on page 14 of this opinion and order, and Table 2, which 

begins on page 15. No further discussion of those changes will appear in this opinion and order. 

4 Except as to revisions in the data handling and calculations requirements of appendix N to 40 

C.F.R. 50. See 78 Fed. Reg. 3086, 3228-32 (Jan. 15, 2013) 

5 See http://www.epa.gov/air/criteria.html (listing of current NAAQS) and http://www.epa.gov/ 

ttn/naaqs/standards/pm/s _pm _ history.html (listing of historical PM NAAQS). Not included in 

the listing of cmrent standards are the 1997 primary annual average NAAQS for PM2.5 in 40 

C.F.R. 50.7(a), the 1997 primary and secondary 24-hour NAAQS for PM2.5 in 40 C.F.R. 50.7(a), 

and the 2006 primary and secondary annual average NAAQS for PM2.s in 40 C.F.R. 50.13(a), all 

of which remain codified. See www.epa.gov/air/criteria.html; 40 C.F.R. 50.7(a) and 50.13(a)

Updated Edition of List of Designated Methods-Section 243.108 

On June 27, 2013, USEPA released a new version of the List of Designated Methods. 

The List is not codified, and the Board did not see that USEP A published a notice for the update 

in the Federal Register. Rather, USEPA's usual practice is simply to post a link to the updated 

version on the Intemet (at www.epa.gov/ttnlamticlcriteria.html). Thus, the Board found the 

update in a routine on-line check for an update. 

The updated version of the List included a number of methods that were modified since 

the last version dated December 17, 2012. The modified methods were the following, arranged 

by crite1ia pollutant: 

Carbon monoxide:

module 801-001000). 

The List of Designated Methods is essential to implementation of the various NAAQS. 

The List specifies the analytical methods that are permissible for the monitoring required to 

demonstrate c nnpliance with ambient air quality standards. Thus, the modifications are 

impmtant to any entity or State using the pmticular methods. 

Any person interested in the substance of the June 27,2013 update to the List of 

Designated Methods should refer to that document. Altematively, interested persons could 

contact USEPA as directed at www.epa.gov/ttn/amtic/criteria.html. 

The December I 7, 20 I 2 version of the List of Designated Methods is incmporated by 

reference in Section 243.108. The Board has updated that incmporation by reference to the June 

27, 2013 version of the List. In addition to updating the version of the List of Designated 

Methods, the Board has made two minor revisions to the existing text of the incmporation by 

reference. When adopting the incorporation by reference in National Ambient Air Quality 

Standards. USEPA Regulations (tlu·ough December 3 L 2012), Rl3-l l (July 25, 2013), the 

Board consistently added the definite mticle before each appearance of"List of Designated 

Methods" tlu·oughout the various substantive provisions at the request of JCAR. For the sake of 

consistency, the Bom·d adds the definite mticle to "List of Designated Methods" in the 

incmporation by reference, which was overlooked in the prior mlemaking. The Bom·d further 

changed "this document" to "the List of Designated Methods" in the appended Board note. 

These added revisions are itemized and summarily outlined in Table 2, which begins on I 5 of 

this opinion and order. 

Request tor Public Comments: The Board requests comments on the update to the 

incmporation by reference to the June 27,2013 version of the List of Designated Methods. 

New FRM for Lead-Section 243.108 

On July 3, 2013 (78 Fed. Reg. 40000), USEPA established a new federal reference 

method (FRM) for lead in total suspended pmticulate matter (Pb-TSP). Establishing the new 

FRM involved amendment of appendix G to 40 C.P.R. 50. The fmmer FRM for Pb-TSP was a 

flame atomic absmption spectrographic (F AAS) method that miginated with the I 978 NAAQS 

for lead. See 43 Fed. Reg. 46246 (Oct. 5, 1978). USEPA adopted a substantially more stt·ingent 

NAAQS for lead in 2008, retaining use of the FRM adopted in 1978. See 73 Fed. Reg. 66964 

(Nov. 12, 2008). USEPA has now established a more teclulologically advanced, more precise, 
10 

and more sensitive inductively coupled plasma-mass spectrometJic (ICP-MS) method for lead 

analyses. The ICP-MS method was based on two methods fom1erly approved as federal 

equivalent methods (FEMs).6 USEPA has now designated the fonner FRM as a FEM. 

Any person interested in the substance of the establislunent of a new FRM for Pb-TSP 

and the designation of the fmmer FRM as an FEM for Pb-TSP should refer to the July 3, 20!3 

Federal Register discussion that accompanied the USEPA amendments. Altematively, 

interested persons could contact USEP A as directed in the Federal Register notice. 

The Board has decided to expedited consideration of USEPA's July 3, 20!3 amendments 

in this docket, rather than wait until the as-yet-umeserved docket for the July l, 20!3 tlu·ough 

December 31, 20!3 update period. The Board has multiple reasons for expedited consideration 

of the July 3, 20!3 amendments: 

Expedited consideration will facilitate implementation of the July 3, 2013 

amendments, as well as the 2008 NAAQS for lead; 

Expedited consideration does not add substantially to the effort required to complete 

amendments based on the USEPA actions dming the period January I, 2013 tlu·ough 

June 30, 20!3, which underlie this proceeding; 

Expedited consideration will obviate very prompt initiation of any NAAQS update 

for the period July I, 20!3 tlu·ough December 3!. 2013 (to complete amendments 

before July 3, 2014); and 

• Expedited consideration could obviate any NAAQS update for the period July I, 

2013 tlu·ough December 31. 2013 (assuming that USEPA does not again act prior to 

Janumy I, 2014 in any way that requires Board action). 

The Board incorporated the July 3, 2013 USEPA amendments without substantive 

changes. The Board updated the incorporation by reference to 40 C.F.R. 50 to the 20!3 edition 

as amended at 78 Fed. Reg. 40000 (July 3, 20!3). The Board found it necessary to depmt from 

the literal USEP A text in doing so; the Board updated the incorporation by reference to appendix 

G to 40 C.F.R. 50, rather than amending substantive language, since the requirements of 

appendix G are incorporated by reference in the Illinois mles. This revisions is itemized and 

snnllllm·ily outlined in Table 2, which begins on page 15 of this opinion and order. 

The Board finther added the fom1er F AAS FRM as an FEM. This required adding a 

reference to the USEP A designation of the former FRM as an FEM to the incorporation by 

reference to the List of Designated Methods. Since the fom1er FRM was codified until 2013 as 

appendix G to 40 C.F.R. 50, the Board as a parenthetical reference to that version of appendix G. 

This revisions is itemized and sUlarily outlined in Table 2, which begins on page 15 of this 

opinion and order.

FRM as an FEM for Pb-TSP. 

Area Designations for the 2010 One-Honr NAAOS for Sulfur Oxides Section 243.122 

On August 5, 2013 (78 Fed. Reg. 47191), US EPA amended various provisions in 40 

C.F .R. 81 to make area air quality designations for 29 areas in 16 states. 7 USEP A designated all 

of the affected areas as non-attainment for the 2010 primary one-hour NAAQS for sulfur oxides. 

Included were two areas in Illinois, as now codified in 40 C.F.R. 81.314 (see 78 Fed. Reg. at 

47199): 

Lemont: Cook County (Lemont Township) and 

Will County (DuPage and Lockpott Townships); and 

Pekin: Tazewell County (Cincinnati and Pekin Townships) and 

Peoria County (Hollis Township). 

These area designations were based on ambient air quality monitoring data collected in 2009, 

2010, and 2011. 

The in1mediate impottance to the State of Illinois of these non-attainment designations is 

that the State must unde1take measures to submit a SIP that meets various federal requirements 

and provides for attaim11ent of the 2010 NAAQS for sulfuT oxides. This submission must occur 

before April 6, 2015, and the SIP must provide for attaimnent no later than October 4, 2018. 78 

Fed. Reg. at 47193; see 42 U.S.C. 7502, 7514, 7514a (2011) (Clean Air Act non-attaimnentprompted SIP requirements). 

The impottance to the Board of these nonattainment designations is the effect that the 

area designations might have on the sunset provision in 40 C.F.R. 50.4(e) for the 1971 NAAQS 

for sulfur oxides. Section 243.122(a)(5) states that the Board will remove the 1971 NAAQS 

after the conditions in 40 C.F.R. 50.4(e) have been fulfilled. Fruther, the Board note attached to 

Section 243 .122( a)( 5) includes explanation of the status of area designations for sulfiu· oxides, 

and USEPA's August 5, 2013 designations makes updating that explanation necessary. 

Any person interested in the substance of the designations of Pekin and Lemont as nonattaimnent for the 2010 NAAQS for sulfur oxides should refer to the July 3, 2013 Federal 

Register discussion that accompanied the USEP A amendments. Alternatively, interested persons 

could contact USEP A as directed in the Federal Register notice. The Board limits attention here 

to the effect those designations may have on the conditions recited in 40 C.F.R. 50.4(e) and on 

the language in the Board note appended to cmTesponding Section 243.122(a)(5). 

7 The states affected were Arizona, Florida, Illinois, Indiana, Iowa, Kentucky, Louisiana, 

Michigan, Missouri, Montana, New Hampshire, Ohio, Pem1sylvania, Tennessee, West Virginia, 

and Wisconsin. 
12 

The Board has decided to expedite consideration of USEPA's August 5, 2013 

amendments in this docket, rather than wait until the as-yet-unreserved docket for the July I, 

2013 tln·ough December 31, 2013 update period. The reasons for expedited consideration of the 

August 5, 2013 amendments are similar to those discussed above with regard to July 3, 2013 

designation of a new FRM: 

• Expedited consideration will more promptly update the Board note appended to 

Section 243.122(a)(5) more accurately infom1 interested persons; 

Expedited consideration will not add substantial effm1 required to complete 

amendments based on the USEPA actions during the period January I, 2013 through 

June 30, 2013; 

• Expedited consideration will obviate prompt initiation of any NAAQS update for the 

period July I, 2013 through December 31. 2013 (to complete amendments before 

August 5, 2014); and 

• Expedited consideration could obviate any NAAQS update for the period July I, 

2013 through December 31. 2013 (assuming that USEPA does not again act prior to 

Janumy I, 2014 in any way that requires Board action). 

The Board has evaluated the effect of the August 5, 2013 USEPA area designations on 

Illinois ambient air quality standards. The present area designations do not yet fulfill the 

conditions of the sunset provisions in the sunset provision for the 1971 NAAQS for sulfur 

oxides. 

The sunset provision for the 1971 primary a!Ulual average and 24-hour NAAQS for sulfur 

oxides provides as follows: 

The [1971 primary annual average and 24-hour NAAQS for sulfur oxides] ... 

will remain applicable to all areas notwithstanding the promulgation of ... [the 

2010 primary one-hour NAAQS for sulfur oxides]. The [ 1971 primary annual 

average and 24-hour NAAQS for sulfur oxides] ... will no longer apply to an 

area one year after the effective date of the designation of that area, pursuant to 

section 107 of the Clea!l Air Act [(42 U.S. C. § 7401 (2011))], for the ... [2010 

primary one-hour NAAQS for sulfur oxides]; except that for areas designated 

nonattainment for the [1971 primary annual average and 24-hour NAAQS for 

sulfur oxides] ... as of the [August 23, 201 OJ effective date of ... [the 201 0 

primary one-hour NAAQS for sulfur oxides], and areas not meeting the 

requirements of a SIP call with respect to requirements for the ... [1971 primary 

annual average and 24-hour NAAQS for sulfur oxides], the [1971 pri.maty annual 

average and 24-hour NAAQS for sulfur oxides] ... will apply until that area 

submits, pursuant to section 191 of the Clean Air Act [(42 U.S. C. § 7514 

(2011))], and EPA approves, an implementation plan providing for attaimnent of 

the ... [2010 primmy one-hour NAAQS for sulfur oxides]. 40 C.F.R. 50.4(e) 

(2013). 
13 

Under this provision, the Board sees two thresholds for detennining that the 1971 NAAQS for 

sulfur oxides no longer applies to an area: 

I. Where the area is not designated non-attainment for the 1971 NAAQS, the 1971 

NAAQS will not apply one year after the effective date of USEPA designation of 

the attainment status of that area for the 2010 NAAQS. 

2. Where USEPA has designated the area non-attainment for the 1971 NAAQS 

before August 23,2010, or a SIP call for the 1971 NAAQS has not been fulfilled 

for the area, the 1971 NAAQS will not apply after USEP A has approved an 

implementation plan (SIP or federal implementation plan) for the area for the 

2010 NAAQS. 

No area of Illinois was designated non-attainment for the 1971 NAAQS for sulfur oxides 

pri01· to August 23, 2010. See 40 C.P.R. 81.314 (2011) (table for "Illinois-son. Thus, only 

the first tin·eshold applies to areas in Illinois: the 1971 NAAQS will no longer apply to an area 

in Illinois one year after the effective date of a USEP A designation of the attainment status of 

that area for the 2010 NAAQS for sulfur oxides. 

The August 5, 2013 designation of the Pekin and Lemont areas as non-attainment for the 

2010 NAAQS for sulfur oxides is effective October 4, 2013. See 78 Fed. Reg. at 47192. The 

1971 NAAQS for sulfur oxides will no longer apply to those areas after October 4, 2014. 

USEPA plans to complete the areas designations to include all areas in the future. See 78 Fed. 

Reg. at 47193-94. 

The August 5, 2013 area designation of two areas of the State is insufficient to prompt 

Board action to remove the 1971 NAAQS for sulfur oxides. The 1971 NAAQS will continue to 

apply to all other areas of the State that USEPA has not yet classified, notwithstanding 

inapplicability to Pekin and Lemont after October 4, 4014. 

The August 5, 2013 area designations for Pekin and Lemont prompt amendment of the 

Board note appended to Section 243.122(a)(5). When adopting the amendments in National 

Ambient Air Quality Standards. USEP A Regulations (tln·ough December 31. 2012), R l 3-11 

(July 25, 2013), the Board added the Board note to explain the then-current status of fulfillment 

of the sunset conditions for the 1971 NAAQS for sulfur oxides. That explanation stated that 

USEPA had not yet made any area designations for the 2010 NAAQS. The explanation noted 

June 3, 2011 Agency reconu11endations to USEPA. The Board must now update the Board note 

explanation to reflect the August 5, 2013 area designations. The revisions to effect this update 

itemized and summarily outlined in Table 2, which begins on page 15 of this opinion and order. 

Requests (or Public Comments: The Board requests comments on the effect of the 

August 5, 2013 USEPA area designations for the Pekin and Lemont areas for the 2010 primary 

one-hourNAAQS for sulfur oxides on the continued effectiveness of the 1971 annual average 

and 24-hour NAAQS for sulfur oxides. The Board requests comments on the revisions made to 

the Board note appended to Section 243.122(a)(5) in response to the August 5, 2013 area 

designations.

Deviations from the Literal Text of the Federal Amendments 

and Non-Federallv Derived Corrections and Clarifications 

The Board routinely examines federal amendments and the base text of mles open for 

amendments to find any areas that need correction or clmification. JCAR and the Office of the 

Secretary of Stat€ also routinely examine the text and suggest corrections and clarifications. 

Sometimes suggestions arise from the Agency, US EPA, or members of the regulated 

community. The Board often makes revisions as a result. The revisions thus made are not 

directly derived from federal amendments. The Board is ever mindful of the limited discretion 

authorized in the context of an identical-in-substance proceeding. The Board is limited to "those 

changes that are necessary for compliance with the Illinois Administrative Code," "technical 

changes that in no way change the scope or meaning of any portion of the regulations," and 

"apparent typographical and grammatical enors." See 415 ILCS 5/7.2(a) and (a)(7) (2012). 

Thus, the Board will only make minor, non-substantive CO!Tections and clarifications in this 

context. These conections are non-substantive in effect. 

Tables follow that document the conections and clarifications made in this proceeding. 

The first table lists the limited number ofUSEPA amendments that were not necessary in this 

proceeding. The second table itemizes the deviations from the literal text of the USEP A 

amendments involved in this proceeding. The third table lists the correction made in this docket 

that was not prompted by federal amendments. 

Tabulations of Deviations from the Literal Text of the Federal Amendments and 

Miscellaneous Board Housekeeping Amendments. 

The tables below list numerous CO!Tections and amendments that are not based on cunent 

federal amendments. Table I lists a number of federal amendments that the Board has not 

included in this docket. Table I gives a brief explanation why the Board has declined to make 

each. Table 2 includes deviations made in the adopted amendments from the verbatim text of the 

federal amendments. Table 3 contains cotTections and clarifications that the Board made in the 

base text involved in the amendments. The amendments listed in Table 3 m·e not directly derived 

from the current federal amendments. Some of the entlies in these tables are discussed further in 

appropriate segments of the general discussion beginning at page 5 of this opinion. Table 4 is a 

listing of revisions made to the text of the amendments from that proposed and set forth in the 

Board's opinion and order of September 5, 2013. Table 4 indicates the changes made, as well as 

the source that suggested each of the changes. Table 5 indicates suggested revisions that the 

Board has not made in adopting these amendments. Each entl·y gives a btief explanation why the 

Bom·d did not incorporate the suggested change.

SUBPART B: STANDARDS AND MEASUREMENT METHODS 

Section 243.120 PM10 and PM2.5 

a) 1 987 Primary and Secondary 24-HourNAAQS for PM10• 

1) The level of the 1 987 primmy and secondary 24-hour NAAQS for PM10 is 

! 50 iJ.g/m3

, 24-hour average concentt·ation. The 1 987 primmy and 
27 

secondary NAAQS for PM10 is attained when the expected number of 

days per calendar year with a 24-hour average concentration above ! 50 

>tg/m3

, as dete1mined in accordance with appendix K to 40 CFR 50, 

incorporated by reference in Section 243.108, is equal to or less than one . 

• 

2) This subsection (a)(2) COJTesponds with 40 CFR 5 1 .6(b ), a provision 

marked "reserved" by USEP A. This statement maintains stmctural 

consistency with the coJTesponding federal regulation. 

3) For the purpose of detem1ining attainment of the 1 987 primary and 

secondary 24-hour NAAQS for PM10, particulate matter must be measured 

in the ambient air as PM10 by a method that fulfills either of the following 

requirements: 

A) An FRM based on appendix J to 40 CFR 50, incorporated 

by reference in Section 243.1 08, and designated by USEPA 

and listed in List of Designated Methods, incorporated by 

reference in Section 243.108; or 

B) An FEM designated by USEPA and listed in List of Designated 

Methods, incorporated by reference in Section 243.108. 

BOARD NOTE: Tins subsection (a) is derived from 40 CFR 50.6 (2Ql2) 

(2013). USEPA adopted 1 997 primary NAAQS for PM10 at 62 Fed. Reg. 38652 

(July 18, 1 997). As a result of a judicial vacatur, USEP A later removed the 

transitional provision relative to the 1 987 NAAQS at 65 Fed. Reg. 80776 (Dec. 

22, 2000) and the 1 997 NAAQS at 69 Fed. Reg. 45595 (July 30, 2004). Thus, the 

1 987 primary and secondary NAAQS for PM10 are included in this subsection (a). 

b) 1 997 Primary and Secondmy Annual Average and 24-Hour NAAQS for PM2.5. 

I) The 1 997 primary and secondary annual average NAAQS for PM2.s is 

15.0 >tg/m3

, annual m·ithmetic mean concentration, and the 1 997 prin1ary 

md secondary 24-hour NAAQS for PM2.s is 65 !Lg/m3, 24-hour average 

concentration, measured in the ambient air as PM2.s by a method that 

fulfills either of the following requirements: 

A) An FRM based on appendix L of 40 CFR 50, incorporated by 

reference in Section 243.108, and designated by USEP A and listed 

in the List of Designated Methods, incorporated by reference in 

Section 243.108; or 

B) An FEM designated by USEPA and listed in the List of Designated 

Methods, incorporated by reference in Section 243 .I 08. 

2) The 1997 primm·y and secondary annual average NAAQS for PM2.5 is met 

when the annual arithmetic mean concentration, as dete1mined in 
28 

accordance with appendix N of 40 CFR 50, incorporated by reference in 

Section 243.108, is less than or equal to 1 5.0 �-tg/m3 

3) The 1 997 primary and secondary 24-hour NAAQS for PM2.5 is met when 

the 98th percentile 24-hour concentration, as detennined in accordance 

with appendix N of 40 CFR 50, incorporated by reference in Section 

243.108, is less than or equal to 65 �-tg/m3 

BOARD NOTE: This subsection (b) is derived from 40 CFR 50.7 (2Ql2) 

(2013). The 2006 primary and secondary annual average and 24-hour NAAQS 

for PM 2.5 differs from the 1 997 standards in that the 24-hour average 

concentration required by the 2006 standard is substantially lower (more 

stringent) than that for the 1 997 standard. The Board has retained the 1 997 

standard in this subsection (b) because USEP A has retained the 1 997 standard in 

40 CFR 50.6. 

c) 2006 Prima1y and Secondary Annual Average and 24-Hour NAAQS for PM25. 

I) The 2006 primary and secondary annual average NAAQS for PM2.5 is 

1 5.0 �-tg/m3, annual arithmetic mean concentration, and the 2006 primary 

and secondary 24-hour NAAQS for PM2.5 is 35 �-tg/m3

, 24-hour average 

concentration, measured in the ambient air as PM2.5 by a method that 

fulfills either of the following requirements: 

A) An FRM based on appendix L of 40 CFR 50, incorporated by 

reference in Section 243.108, and designated by USEPA and listed 

in the List of Designated Methods, incmporated by reference in 

Section 243.108; or 

B) An FEM designated by USEPA and listed in the List of Designated 

Methods, incorporated by reference in Section 243.108. 

2) The 2006 primary and secondary annual average NAAQS for PM2.5 is met 

when the annual arithmetic mean concentration, as detennined in 

accordance with appendix N of 40 CFR 50, incmporated by reference in 

Section 243.1 08, is less than or equal to 1 5.0 �-tg/m3

• 

3) The 2006 primary and secondary 24-hour NAAQS for PM25 is met when 

the 98th percentile 24-hour concentration, as detennined in accordance 

with appendix N of 40 CFR 50, incorporated by reference in Section 

243.108, is less than or equal to 3 5 �-tg/m3 

BOARD NOTE: This subsection (c) is derived from 40 CFR 50. 13 (2Ql2) 

(2013). 

d) 2012 Primary Annual Average and 24-Hour NAAOS for PM?.S 
29 

1) The 2012 primary annual average NAAQS for PM25 is 12.0 ug/m3 annual 

arithmetic mean concentration. and the 2012 primmy 24 hour NAAQS for 

PMo.5 is 35 ug/m3 24-hour average concentration. measured in the ambient 

air as PMo5 by a method that fulfills either of the following requirements: 

A) An FRM based on appendix L of 40 CFR 50. incomorated by 

reference in Section 243.108. and designated by USEPA and listed 

in List of Designated Methods. incmporated by reference in 

Section 243.108: or 

B) An FEM designated by USEPA and listed in List of Designated 

Methods. incomorated by reference in Section 24 3.108. 

2) The 2012 primary annual NAAQS for PM2.5 is met when the mmual 

arithmetic mean concentration. as detennined in accordance with appendix 

N of 40 CFR 50. incomorated by reference in Section 243.108. is less than 

or equal to 12.0 ug/m3 

3) The 2012 primary 24-hour NAAQS for PMo.5 is met when the 98th 

percentile 24-hour concentration. as detennined in accordance with 

appendix N of 40 CFR 50. incmporated by reference in Section 243.108. 

is less than or equal to 35 ug/m3 

BOARD NOTE: This subsection (d) is derived from 40 CFR 50.13 (2013). 

(Source: Amended at 37 IlL Reg. __ , effective--

 

Section 243.122 Sulfur Oxides (Sulfur Dioxide) 

a) 1 97 1 Primary Annual Average and 24-Hour NAAQS for Sulfur Oxides (as Sulfur 

Dioxide (S02)). 

1) The level of the 1 97 1 primary annual average NAAQS for sulfur oxides is 

0.030 ppm, not to be exceeded in a calendar year. The annual arithmetic 

mean must be rounded to tln·ee decimal places (fractional parts equal to or 

greater than 0.0005 ppm must be rounded up). 

2) The level of the 1 97 1 primary 24-hour NAAQS for sulfur oxides is 0.14 

ppm, not to be exceeded more than once per calendar year. The 24-hour 

averages must be dete1mined from successive non-overlapping 24-hour 

blocks starting at midnight each calendar day and must be rounded to two 

decimal places (fractional pmts equal to or greater than 0.005 ppm must be 

rounded up). 

3) Sulfur oxides must be measured in the ambient air as S02 by the FRM 

described in appendix A-2 to 40 CFR 50, incmporated by reference in 

Section 243 .108, or by an FEM designated by US EPA and listed in the 

List of Designated Methods, inco1porated by reference in Section 243.108. 
30 

4) To demonstrate attainment, the annual aritlnnetic mean and the secondhighest 24-hour averages must be based upon hourly data that are at least 

75 percent complete in each calendar qum1er. A 24-hour block average 

must be considered valid if at least 75 percent of the hourly averages for 

the 24-hour period are available. In the event that only 1 8-, 1 9-, 20-, 21-, 

22-, or 23-hour averages are available, the 24-hour block average must be 

computed as the sum of the available hourly averages using the number of 

hours (i.e., 1 8, 1 9, etc.) as the divisor. Ifless than 18-hour averages are 

available, but the 24-hour average would exceed the level of the standard 

when zeros are substituted for the missing values, subject to the rounding 

mle of subsection (b) of this Section, this must be considered a valid 24-

hour average. In this case, the 24-hour block average must be computed 

as the sum of the available hourly averages divided by 24. 

5) The 1 971 primary annual average and 24-hour NAAQS for sulfur oxides 

set fm1h in this subsection (a) remains applicable to all areas 

notwithstanding the promulgation of the 2010 primmy one-hour NAAQS 

for sulfur oxides in subsection (c) of this Section. The Board will delete 

the 1971 primary annual average and 24-hour NAAQS for sulfur oxides 

set fm1h in this subsection (a) after fulfillment of the conditions recited by 

USEPA in conesponding 40 CFR 50.4(e). 

BOARD NOTE: Corresponding 40 CFR 50.4(e) recites that the 1971 

prin1ary NAAQS for sulfur oxides remains effective in two types of areas 

for which USEP A has not yet approved an implementation plan for 

attainn1ent with the 20 I 0 prin1ary one-hour NAAQS for sulfur oxides. 

The first type of area is one that USEP A had designated as non-attainment 

for that standard as of the effective date of the 2010 primary one-hour 

NAAQS for the 1 971 primmy NAAQS for sulfur oxides as of the effective 

date of the 2010 NAAQS. That date was August 23, 2010. See 75 Fed. 

Reg. 35520 (June 22, 20 1 0). As of that date, USEPA had not designated 

any area in Illinois as non-attainment. See 40 CFR 81.3 14 (201 0). The 

Board is unaware of any USEPA SIP call for any area of Illinois relative 

to the 1971 primmy NAAQS for sulfuT oxides. As efDe

er 31, 2012, 

USEP A had net yet designated the attaimnent status of two areas in 

Illinois for the 2010 primary one-hour NAAQS for sulfur oxides on 

Angust 5. ?013. effective October 4. 201 3. See 40 CFR 81.314 (2012) 

(201 3). as amended at 78 Fed. Reg. 47191 (Aug. 5. 2013) (Lemont and

primary annual average and 24-hour NAAQS for sulfur oxides will no 

longer apply to those two designated areas effective October 4. 2014: 

although the NAAQS will continue to apply to all other areas of Illinois 
31 

after that date. When the conditions of tl'lis subsection (a)( 5) have been 

fulfilled as to all areas of Illinois, or USEP A has removed 40 CFR 50.4, 

the Board will remove the standard of this subsection (a) as obsolete. 

BOARD NOTE: This subsection (a) is derived from 40 CFR 50.4 (2Ql2). 

b) 1971 Secondary Three-Hour NAAQS for Sulfur Oxides (as S02). 

I) The level of the 1 971 secondary tlu·ee-hour NAAQS for sulfur oxides is 

0.5 ppm, not to be exceeded more than once per calendar year. The tlu·eehour averages must be dete1mined from successive non-overlapping tlu·eehour blocks starting at midnight each calendar day and must be rounded to 

one decimal place (fi·actional parts equal to or greater than 0.05 ppm must 

be rounded up). 

2) Sulfur oxides must be measured in the ambient air as S02 by the FRM 

described in appendix A-2 to 40 CFR 50, incmporated by reference in 

Section 243.108, or by an FEM designated by USEPA and listed in List of 

Designated Methods, incmporated by reference in Section 24 3 .I 08. 

3) To demonstrate attainment, the second-highest tlu·ee-hour average must be 

based upon hourly data that are at least 7 5 percent complete in each 

calendar qua1ter. A three-hour block average must be considered valid 

only if all three hourly averages for the tlu·ee-hour period are available. If 

only one or two hourly averages are available, but the tlu·ee-hour average 

would exceed the level of the standard when zeros are substituted for the 

missing values, subject to the rounding mle of subsection (b )(I) of this 

Section, tl'lis must be considered a valid tlu·ee-hour average. In all cases, 

the tlu·ee-hour block average must be computed as the sum of the hourly 

averages divided by three. 

BOARD NOTE: This subsection (b) is derived from 40 CFR 50.5 (2Ql2). 

c) 201 0 Primary One-Hour NAAQS for Sulfur Oxides (as S02). 

I) The level of the 2010 primmy one-hour NAAQS for sulfur oxides is 75 

ppb, measmed in the ambient air as S02. 

2) The 2010 one-hour primary NAAQS for sulfur oxides is met at an ambient 

air quality monitming site when the tlu·ee-year average of the annual (99th 

percentile) of the daily maximum one-hour average concentrations is less 

than or equal to 75 ppb, as detem'lined in accordance with appendix T of 

40 CFR 50, incmporated by reference in Section 243.108. 

3) The level of the 2010 one-hour primmy NAAQS for sulfur oxides must be 

measured by an FRM based on appendix A-1 or A-2 of 40 CFR 50, 

incmporated by reference in Section 243.108, or by an FEM designated by 
32 

USEP A and listed in List of Designated Methods, incorporated by 

reference in Section 243 .I 08. 

BOARD NOTE: This subsection (c) is derived fi·om 40 CFR 50. 17 (2012). The 

1 971 primary NAAQS for S02 remains in effect until the federal conditions of 40 

CFR 50.4(e) have been fulfilled, as outlined in subsection (a)(5) of this Section 

and the appended Board note.

infonnation in t!J.is table of revised deadlines only applies to data that USEP A will use to 

establish the ffinitial area designations for new or revised NAAQS. USEP A stated that the 

general schedule in this table applies for all other purposes, most notably, for data that USEPA 

will use for redesignations to attainment. Con·esponding table 1 to 40 CFR 50.14(c)(2) eites the

NOTICE OF ADOPTED AMENDMENTS 

The differences are limited to minor, non-substantive revisions, including one change in 

citation format, addition of two commas, and one correction to spelling. The changes are 

intended to have no substantive effect. The intent is to add clarity to the rules without 

deviation from the substance of the federal amendments on which this proceeding is 

based. 

12) Have all the changes agreed upon by the board and JCAR been made as indicated in the 

agreements issued by JCAR? Section 1 O(H) of the Environmental Protection Act [ 415 

ILCS 5/10(H)] provides that Section 5-35 of the Administrative Procedure Act [5 ILCS 

1 00/5-35] does not apply to this rulemaking. Because this rulemaking is not subject to 

Section 5-35 ofthe AP A, it is not subject to First Notice or to Second Notice review by 

JCAR. 

Since the Notices of Proposed Amendments appeared in the September 20, 2013 issue of 

the Illinois Register, the Board received a number of suggestions for revisions from 

JCAR. The Board evaluated each suggestion and incorporated a number of changes into 

the text as a result, as detailed in the opinion and order ofNovember 21, 2013 in docket 

R14-6, as indicated in item 11 above. See the November 21, 2013 opinion and order in 

docket R14-6 for additional details on the JCAR suggestions and the Board actions with 

regard to each. One table in that opinion itemizes the changes made in response to 

various suggestions. Another table indicates JCAR suggestions not incorporated into the 

text, with a brief explanation for each. 

13) Will these amendments replace emergency amendments currently in effect? No 

14) Are there any other amendments pending on this Part? No. 

15) Summary and purpose of amendments: The following briefly describes the subjects and 

issues involved in this rulemaking. A comprehensive description is contained in the 

Board's opinion and order of September 5, 2013, adopting amendments in docket Rl4-6, 

which opinion and order is available from the address below. 

The R14-6 proceeding relates to the Illinois ambient air quality requirements in 35 Ill. 

Adm. Code 243 of the Illinois air pollution control rules. These amendments would 

update the lllinois ambient air quality requirements to correspond with amendments to 

the federal National Ambient Air Quality Standards (NAAQSs) that the United States 

Environmental Protection Agency (USEP A) adopted during the period January 1, 2013 

through June 30, 2013. The Federal NAAQS are codified at 40 C.P.R. 50. During this 

period, USEPA amended its NAAQSs as follows:

POLLUTION CONTROL BOARD 

NOTICE OF ADOPTED AMENDMENTS 

January 15,2013 

(78 Fed. Reg. 3086) 

June27, 2013 

USEP A adopted new 2012 primary 24-hour and 

annual average NAAQS for PM2.5. USEP A further 

revised the interpretation of the NAAQS for PM25• 

USEPA updated the "List of Designated Reference 

and Equivalent Methods." 

The Board has further included amendments based on two USEP A actions that occurred 

after July 1, 2013. Those two federal actions are described as follows: 

July 3, 2013 

(78 Fed. Reg. 40000) 

August 5, 2013 

(78 Fed. Reg. 47191) 

USEP A amended appendix G to 40 C.P.R. 50 to 

establish a new federal reference method (FRM) for 

measuring lead in total suspended particulate matter 

for the purposes of the lead NAAQS. 

USEP A made area designations for the 2010 

NAAQS for sulfur dioxide. 

Tables appear in the Board's opinion and order of September 20, 2013 in docket Rl4-6 

that list a limited correction that is numerous corrections and amendments that are not 

based on current federal amendments. The tables contain deviations from the literal text 

of the federal amendments underlying these amendments, as well as corrections and 

clarifications that the Board made in the base text involved. Persons interested in the 

details of those corrections and amendments should refer to the November 21, 2013 

opinion and order in docket Rl4-6. 

Section lO(H) of the Environmental Protection Act [415 ILCS 5/lO(H)] provides that 

Section 5-35 oftheAdministrativeProcedureAct [5 ILCS 100/5-35] does not apply to 

this rulemaking. Because this rulemaking is not subject to Section 5-35 of the APA, it is 

not subject to First Notice or to Second Notice review by the Joint Committee on

Section 243,120 PM10 and PM2.s 

a) 1987 Primary and Secondary 24-Hour NAAQS for PMw. 

1) 

2) 

The level ofthe 1987 primary and secondary 24-hour NAAQS for PMw is 

150 J.Lg/m3

, 24-hour average concentration. The 1987 primary and 

secondary NAAQS for PM10 is attained when the expected number of 

days ~er calendar year with a 24-hour average concentration above 150 

J.lg/m , as determined in accordance with appendix K to 40 CPR 50, 

incorporated by reference in Section 243.108, is equal to or less than one. 

This subsection (a)(2) corresponds with 40 CPR 51.6(b ), a provision 

marked ''reserved" by USEP A. This statement maintains structural 

consistency \vith the corresponding federal regulation.

NOTICE OF ADOPTED AMENDMENTS 

3) For the purpose of determining attainment of the 1987 primary and 

secondary 24-hour NAAQS for PM10, particulate matter must be measured 

in the ambient air as PM10 by a method that fulfills either of the following 

requirements: 

A) An FRM based on appendix J to 40 CFR 50, incorporated 

by reference in Section 243.108, and designated by US EPA 

and listed in List of Designated Methods, incorporated by 

reference in Section 243.1 08; or 

B) An FEM designated by US EPA and listed in List of Designated 

Methods, incorporated by reference in Section 243.108. 

BOARD NOTE: This subsection (a) is derived from 40 CFR 50.6 (2012)_ 

(2013). USEP A adopted 1997 primary NAAQS for PMw at 62 Fed. Reg. 38652 

(July 18, 1997). As a result of a judicial vacatur, USEPA later removed the 

transitional provision relative to the 1987 NAAQS at 65 Fed. Reg. 80776 (Dec. 

22, 2000) and the 1997 NAAQS at 69 Fed. Reg. 45595 (July 30, 2004). Thus, the 

1987 primary and secondary NAAQS for PM10 are included in this subsection (a). 

b) 1997 Primary and Secondary Annual Average and 24-Hour NAAQS for PM2.S· 

1) The 1997 ~rimary and secondary annual average NAAQS for PM2.s is 

15.0 1-!g/m , annual arithmetic mean concentration, and the 1997 primary 

and secondary 24-hour NAAQS for PM2.s is 65 !lg/m3

, 24-hour average 

concentration, measured in the ambient air as PM2.s by a method that 

fulfills either of the following requirements: 

A) An FRM based on appendix L of 40 CFR 50, incorporated by 

reference in Section 243.108, and designated by USEP A and listed 

in the List of Designated Methods, incorporated by reference in 

Section 243.108; or 

B) An FEM designated by US EPA and listed in the List of Designated 

Methods, incorporated by reference in Section 243.108. 

2) The 1997 primary and secondary annual average NAAQS for PM2.s is met 

. when the annual arithmetic mean concentration, as determined in 

accordance with appendix N of 40 CFR 50, incorporated by reference in 

Section 243.108, is less than or equal to I 5.0 !lg/m3

3) The 1997 primary and secondary 24-hour NAAQS for PM25 is met when 

the 98th percentile 24-hour concentration, as determined in accordance 

with appendix N of 40 CPR 50, incorporated by reference in Section 

243 .1 08, is less than or equal to 65 11g/m3

• 

BOARD NOTE: This subsection (b) is derived from 40 CPR 50.7 (2012) 

(2013). The 2006 primary and secondary annual average and 24-hour NAAQS 

for PM 2.5 differs from the 1997 standards in that the 24-hour average 

concentration required by the 2006 standard is substantially lower (more 

stringent) than that for the 1997 standard. The Board has retained the 1997 

standard in this subsection (b) because USEP A has retained the 1997 standard in 

40 CFR50.6. 

c) 2006 Primary and Secondary Annual Average and 24-Hour NAAQS for PM2.s. 

1) The 2006 ~rimary and secondary annual average NAAQS for PM2.s is 

15.0 fLg/m , annual arithmetic mean concentration, and the 2006 primary 

and secondary 24-hour NAAQS for PM2.s is 35 fLg/m3

, 24-hour average 

concentration, measured in the ambient air as PM25 by a method that 

fulfills either of the following requirements: 

A) An FRM based on appendix L of 40 CPR 50, incorporated by 

reference in Section 243.108, and designated by US EPA and listed 

in the List of Designated Methods, incorporated by reference in 

Section 243.108; or 

B) An FEM designated by USEP A and listed in the List of Designated 

Methods, incorporated by reference in Section 243.108. 

2) The 2006 primary and secondary annual average NAAQS for PM25 is met 

when the annual arithmetic mean concentration, as determined in 

accordance with appendix N of 40 CPR 50, incorporated by reference in 

Section 243.108, is less than or equal to 15.0 fLg/m3 

3) The 2006 primary and secondary 24-hour NAAQS for PM2.s is met when

d) 2012 Primary Annual Average and 24-Hour NAAOS for PMz.s 

I) The 2012 primary annual average NAAQS for PMz.s is 12.0 !lg/m3 annual 

arithmetic mean concentration, and the 2012 primary 24-hour NAAQS for 

PM2.s is 35 ug/m3 24-hour average concentration, measured in the ambient 

air as PMz.s by a method that fulfills either of the following requirements: 

A) An FRM based on appendix L of 40 CPR 50, incorporated by 

reference in Section 243.108, and designated by US EPA and listed 

in List of Designated Methods, incorporated by reference in 

Section 243.108; or 

B) An FEM designated by USEPA and listed in List of Designated 

Methods, incorporated by reference in Section 243.108. 

2) The 2012 primary annual NAAOS for PMz.s is met when the annual 

arithmetic mean concentration, as determined in accordance with appendix 

N of 40 CFR 50. incorporated by reference in Section 243.108, is less than 

or equal to 12.0 11g/m3

• 

3) The 2012 primary 24-hour NAAOS for PM25 is met when the 98th 

percentile 24-hour concentration, as determined in accordance with 

appendix N of 40 CFR 50, incorporated by reference in Section 243.108, 

is less than or equal to 35 !.Lg/m3

Section 243.122 Sulfur Oxides (Sulfur Dioxide) 

a) 1971 Primary A1mual Average and 24-HourNAAQS for Sulfur Oxides (as Sulfur 

Dioxide (SOz)). 

1) The level of the 1971 primary annual average NAAQS for sulfur oxides is 

0.030 ppm, not to be exceeded in a calendar year. The annual arithmetic 

mean must be rounded to three decimal places (fractional parts equal to or 

greater than 0.0005 ppm must be rounded up). 

2) The level of the 1971 primary 24-hour NAAQS for sulfur oxides is 0,14 

ppm, not to be exceeded more than once per calendar year. The 24-hour 
ILLINOIS REGISTER 

POLLUTION CONTROL BOARD 

NOTICE OF ADOPTED AMENDMENTS 

averages must be determined from successive non-overlapping 24-hour 

blocks starting at midnight each calendar day and must be rounded to two 

decimal places (fractional parts equal to or greater than 0.005 ppm must be 

rounded up). 

3) Sulfur oxides must be measured in the ambient air as S02 by the FRM 

described in appendix A-2 to 40 CFR 50, incorporated by reference in 

Section 243.108, or by an FEM designated by USEP A and listed in the 

List of Designated Methods, incorporated by reference in Section 243.108. 

4) To demonstrate attaimnent, the annual arithmetic mean and the secondhighest 24-hour averages must be based upon hourly data that are at least 

75 percent complete in each calendar quarter. A 24-hour block average 

must be considered valid if at least 75 percent of the hourly averages for 

the 24-hour period are available. In the event that only 18-, 19-, 20-,21-, 

22-, or 23-hour averages are available, the 24-hour block average must be 

computed as the sum of the available hourly averages using the number of 

hours (i.e., 18, 19, etc.) as the divisor. Ifless than 18-hour averages are 

available, but the 24-hour average would exceed the level of the standard 

when zeros are substituted for the missing values, subject to the rounding 

rule of subsection (b) of this Section, this must be considered a valid 24-

hour average. In this case, the 24-hour block average must be computed 

as the sum of the available hourly averages divided by24. 

5) The 1971 primary annual average and 24-hour NAAQS for sulfur oxides 

set forth in this subsection (a) remains applicable to all areas 

notwithstanding the promulgation of the 2010 primary one-hour NAAQS 

for sulfur oxides in subsection (c) of this Section. The Board will delete 

the 1971 primary annual average and 24-hour NAAQS for sulfur oxides 

set forth in this subsection (a) after fulfillment of the conditions recited by 

USEPA in corresponding 40 CFR 50.4(e). 

BOARD NOTE: Corresponding 40 CFR 50.4(e) recites that the 1971 

primary NAAQS for sulfur oxides remains effective in two types of areas 

for which USEP A has not yet approved an implementation plan for 

attaimnent with the 2010 primary one-hour NAAQS for sulfur oxides. 

The first type of area is one that US EPA had designated as non-attaimnent 

for that standard as of the effective date of the 2010 primary one-hour 

NAAQS for the 1971 primary NAAQS for sulfur oxides as of the effective 

date of the 2010 NAAQS. That date was August 23,2010. See 75 Fed. 
ILLINOIS REGISTER 

POLLUTION CONTROL BOARD 

NOTICE OF ADOPTED AMENDMENTS 

Reg. 35520 (June 22, 2010). As of that date, US EPA had not designated 

any area in Illinois as non-attainment. See 40 CFR 81.314 (201 0). The 

Board is unaware of any USEP A SIP call for any area of Illinois relative 

to the 1971 primary NAAQS for sulfur oxides. As efDeeemller 31, 2()12, 

USEP A had uet yet designated the attainment status of two areas in 

Illinois for the 2010 primarv one-hour NAAOS for sulfur oxides on 

August 5, 2013. effective October 4. 2013. See 40 CFR 81.31 q (2012)_ 

(2013), as amended at 78 Fed. Reg. 47191 (Aug. 5, 2013) (Lemont and 

Pekin areas). The Ageney reeemmended that U8BPA designate limited 

areas efillineis as nan attainment with the 2010 J3rimary ene heur 

NfJ.Q8. See letter efJune 2, 2011 iTem Laurel Kreaek, Chief, Bureau ef 

Air, Ageuey, te Cheryl A. Nev;ten, Direeter, Offiee efthe Air aud

se2designatieus/ree!etters/R5 IL res wteehaua!ysis.pEit). The 1971 

primary annual average and 24-hour NAAOS for sulfur oxides will no 

longer apply to those two designated areas effective October 4. 2014; 

although the NAAOS will continue to apply to all other areas of Illinois 

after that date. When the conditions of this subsection (a)(5) have been 

fulfilled as to all areas of Illinois, or USEPA has removed 40 CPR 50.4, 

the Board will remove the standard of this subsection (a) as obsolete. 

BOARD NOTE: This subsection (a) is derived from 40 CPR 50 A (2012). 

b) 1971 Secondary Three-Hour NAAQS for Sulfur Oxides (as S02). 

1) The level of the 1971 secondary three-hour NAAQS for sulfur oxides is 

0.5 ppm, not to be exceeded more than once per calendar year. The threehour averages must be determined from successive non-overlapping threehour blocks starting at midnight each calendar day and must be rounded to 

one decimal place (fractional parts equal to or greater than 0.05 ppm must 

be rounded up). 

2) Sulfur oxides must be measured in the ambient air as S02 by the PRM 

described in appendix A-2 to 40 CPR 50, incorporated by reference in 

Section 24 3.1 08, or by an PEM designated by USEP A and listed in List of 

Designated Methods, incorporated by reference in Section 243.108. 

3) To demonstrate attainment, the second-highest three-hour average must be 

based upon hourly data that are at least 75 percent complete in each 

calendar quarter. A three-hour block average must be considered valid 

only if all three hourly averages for the three-hour period are available. If 
ILLINOIS REGISTER 

POLLUTION CONTROL BOARD 

NOTICE OF ADOPTED AMENDMENTS 

only one or two hourly averages are available, but the three-hour average 

would exceed the level of the standard when zeros are substituted for the 

missing values, subject to the rounding rule of subsection (b )(1) of this 

Section, this must be considered a valid three-hour average. In all cases, 

the three-hour block average must be computed as the sum of the hourly 

averages divided by three. 

BOARD NOTE: This subsection (b) is derived from 40 CPR 50.5 (2012). 

c) 2010 Primary One-Hour NAAQS for Sulfur Oxides (as SOz). 

1) The level of the 2010 primary one-hour NAAQS for sulfur oxides is 75 

ppb, measured in the ambient air as S02• 

2) The 2010 one-hour primary NAAQS for sulfur oxides is met at an ambient 

air quality monitoring site when the three-year average of the annual (99th 

percentile) of the daily maximum one-hour average concentrations is less 

than or equal to 7 5 ppb, as determined in accordance with appendix T of 

40 CPR 50, incorporated by reference in Section 243.108. 

3) The level of the 2010 one-hour primary NAAQS for sulfur oxides must be 

measured by an PRM based on appendix A-1 or A-2 of 40 CPR 50, 

incorporated by reference in Section 243.108, or by an PEM designated by 

USEPA and listed in List of Designated Methods, incorporated by 

reference in Section 243.108. 

BOARD NOTE: This subsection (c) is derived from 40 CPR 50.17 (2012). The 

1971 primary NAAQS for SOz remains in effect until the federal conditions of 40 

CPR 50.4(e) have been fulfilled, as outlined in subsection (a)(5) of this Section 

and the appended Board note.

BOARD NOTE: Derived from table 1 to 40 CPR 50.14(c) (2012). USEPA noted that the 

information in this table of revised deadlines only applies to data that US EPA will use to 

establish the ffilal..initial area designations for new or revised NAAQS. USEPA stated that the 

general schedule in this table applies for all other purposes, most notably, for data that USEPA 

will use for redesignations to attainment. Corresponding table 1 to 40 CPR 50.14(c)(2) eites the 

2010 one hour J>IAAQS for nitrogen mdees as "80 1 OG PPB, final level TBD" and the 2010 one 

hour J>!t\,AQS for sulfur eJ<iees as "80 100 PPB, final level TBD." The adopted 2010 one hour 

Nf'u\QS for NO;, at 40 CPR SG.ll(f) is JOG ppb and the adopted 2010 one hour NAAQS for SO, 

is 7S ppb. The Beard has used the aetual Nl'a\QS for these eoutamiuauts iu this Table A. 

Further, eorrespoudiug table 1 to 4Q CPR 50.14(e) iueludes endnotes "a" and "b" iudieate 

whether dates for NO.x and SO. are ehanged or uuehauged, whleh the Beard has omitted, siuee 

endnotes vlill ser.·e ue purpose iu the Illinois regulations. includes a footnote "a," which 

indicates that the tabulated deadlines for event flagging and initial description for 2012 and 2013 

data under the 2012 primary annual average NAAQS for PMz.s are the same as those prescribed 

by 40 CPR 50.14 (corresponding with Section 243.105). The Board omitted those footnotes as 

unnecessary in the Illinois rules. Corresponding federal table 1 states that the 2012 primary 

annual average NAAOS for PM25 was "Promulgated December 14, 2012." Although the 

Administrator ofUSEPA signed adopted rule on that date, publication did not occur until 

January 15, 2013. See 78 Fed. Reg. 3086, 3276 (Jan. 15, 2013). The Board has used the Federal 

Register citation and date.
