**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 (201**  **1)) 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 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.**

**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:** 

**Federal Action**  **Date (citation) Description**  **of the**  **Action January**  **15, 2013**  **New 2012**  **Primary 24-Hour**  **and (78**  **Fed. Reg.**  **3086) Annual Average NAAQS**  **for PM**  **2.s June**  **27, 2013**  **Update to**  **the List**  **of Designated**  **Methods 7**

**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 standar** **ds . 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).** 
**DISCUSS ION** 

**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 24** **3.120**

**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/m 3** **) and**  **a 24-hour**  **average standard**  **of 35**  **mg/m 3** 

**. 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/m** **3**
**, 24-hour**  **average concentration** 
**1997 Primary**  **and Secondary**  **Annual Average**  **NAAQS for**  **PM 2.5:**

**, 24-hour**  **average concentration,**  **98th percentile,**  **averaged over**  **three years**  **2012 Primary**  **Annual Average**  **NAAQS for**  **PM2.5:**

**12.0 >tg/m** **3 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**  **PM 10**  **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.**

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

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**

### 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**  **Sulf ur**  **Oxides-Section 24** **3.1 22** 
**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 NAAQ** **S 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** **AAQ S**  **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-attainment prompted**  **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 NAAQ** **S for**  **sulfur oxides.**  **Section 243.122(a)(5)**  **states that**  **the Board**  **will remove**  **the 1971**  **NAAQ S**  **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**  **non attainment**  **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**  **(SI P**  **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 "Il** **linoi s-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 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 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.**

**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 long**  **telm 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).**

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 ofthe 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, orby an FEM desigoated by USEPA and listed in the List ofDesignated 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 ifat least 75 percent ofthe 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 ofthe 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 ofthe standard when zeros are substituted for the missing values, subject to the rounding rule ofsubsection (b) ofthis Section, this must be considered a valid 24- hour average. In this case, the 24-hour block average must be computed
as the sum ofthe 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 ofthe 2010 primary one-hour NAAQS for sulfur oxides in subsection (c) ofthis Section.

the 1971 primary annual average and 24-hour NAAQS for sulfur oxides set forth in this subsection (a) after fulfillment ofthe 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 ofareas 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 ofarea is one that USEPA had designated as non-attainment for that standard as ofthe effective date ofthe 2010 primary one-hour NAAQS for the 1971 primary NAAQS for sulfur oxides as ofthe effective date ofthe2010 NAAQS. That date was Augnst 23,2010. See 75 Fed. Reg. 35520 (June 22, 201 0). As ofthat date, USEPA had not designated any area in Illinois as non-attainment. See 40 CFR 81.314 (2010). The Board is unaware ofany USEPA SIP call for any area ofIllinois relative to the 1971 primaryNAAQS for sulfur oxides. As ofDeeem!Jer 31, 2().l.;l, USEPA had net yet designated the attainment status oftwo areas in Illinois for the 2010 primary one-hour NAAOS for sulfur oxides on August 5. 2013. effective October 4. 2013.

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 ofthe standard when zeros are substituted for the missing values, subject to the rounding rule of subsection (b)( 

### 1) ofthis Section, this must be considered a valid three-hour average. In all cases, the three-hour block average must be computed as the sum ofthe hourly averages divided by three.

**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 (N** **ov. 12,** **2008). USEPA**  **has now**  **established a**  **more teclulologically**  **advanced, more**  **precise, 10** 

**and more sensitive**  **inductively coupled**  **plasma-mass spectrometJic**  **(I CP-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**

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.

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**  **non attaimnent**  **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).**

**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**

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**

**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 differences are limited to minor, non-substantive revisions, including one change in citation format, addition oftwo 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 ofthe 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 byJCAR? Section 1 

### O(H) ofthe Environmental Protection Act [ 415 ILCS 5/10(H)] provides that Section 5-35 ofthe 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 APA, it is not subject to First Notice or to Second Notice review by JCAR.
Since the Notices ofProposed Amendments appeared in the September 20, 2013 issue of the Illinois Register, the Board received a number ofsuggestions for revisions from JCAR. The Board evaluated each suggestion and incorporated a number ofchanges 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 briefexplanation 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 ofamendments: 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 ofthe 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 (USEPA) 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:

### USEPA further revised the interpretation ofthe NAAQS for PM25 • 

### USEPA updated the "List ofDesignated Reference and Equivalent Methods."

The Board has further included amendments based on two USEPA 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) USEPA 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 ofthe lead NAAQS.
USEPA 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 ofthe 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 ofthose corrections and amendments should refer to the November 21, 2013 opinion and order in docket Rl4-6.
Section lO(H) ofthe 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.

This subsection (a)(2) corresponds with 40 CPR 51.6(b), a provision marked ''reserved" by USEPA. This statement maintains structural consistency \vith the corresponding federal regulation.

### ILLINOIS REGISTER
POLLUTION CONTROL BOARD
NOTICE OF ADOPTED AMENDMENTS 3) For the purpose ofdetermining attainment ofthe 1987 primary and secondary 24-hour NAAQS for PM10, particulate matter must be measured in the ambient air as PM 10 by a method that fulfills either ofthe following requirements: A) An FRM based on appendix J to 40 CFR 50, incorporated by reference in Section 243.108, and designated by USEPA and listed in List ofDesignated Methods, incorporated by reference in Section 243.1 08; or B) An FEM designated by USEPA and listed in List ofDesignated Methods, incorporated by reference in Section 243.108.
BOARD NOTE: This subsection (a) is derived from 40 CFR 50.6 (2012)_ (2013). USEPA adopted 1997 primary NAAQS for PMw at 62 Fed. Reg. 38652 (July 18, 1997). As a result of ajudicial 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 PM 10

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 ofthe 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 ofthe 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

### 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 ofDesignated 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 ifat least 75 percent ofthe 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 ofthe 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 ofthe standard when zeros are substituted for the missing values, subject to the rounding rule ofsubsection (b)

as the sum ofthe 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 ofthe 2010 primary one-hour NAAQS for sulfur oxides in subsection (c) ofthis 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 ofthe 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 ofareas for which USEPA 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 USEPA had designated as non-attaimnent for that standard as ofthe effective date ofthe 2010 primary one-hour NAAQS for the 1971 primary NAAQS for sulfur oxides as ofthe effective date ofthe 2010 NAAQS.
