0) Has JCAR issued a statement ofobjections to these rules? No. Section 1 O(H) ofthe Environmental Protection Act [415 ILCS 5/IO(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 isnot subject to Section 5-35 ofthe APA, it is not subject to FirstNotice or to Second Notice review bythe Joint Committee on Administrative Rules (JCAR). 11) Differences between the proposal aad the final version: A table that appears in the Board's opinion and order ofJuly25, 2013 in docket R13-11 summarizes the differences between the amendments adopted in that order aad those proposed bythe Board in an opinion and order dated May 16, 2013, in docket Rl3-ll. Many ofthe differences are explained in greater detail in the Board's opinion and order adoptingthe amendments. Thedifferences are limited to corrections to the text ofthe rules, including removal ofthe 1979 primary one-hour NAAQS for ozone, which applies to no areaofIllinois, and several minor corrections promptedby JCARreview ofthe text. 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) Haveall the changes agreed upon by the board and JCARbeen made as indicated in the agreements issued by JCAR? Section 1 O(H) ofthe Environmental Protection Act [ 415 ILCS 5/1O(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 orto Second Notice review by JCAR. Since the Notices ofProposed Amendments appeared in the May 31, 2013 issue ofthe Illinois Register, the Board received a number ofsuggestions for revisions from JCAR. TheBoard evaluated each suggestion and incorporated a number ofchanges into the text as a result, as detailed in the opinion and order ofJuly 25, 2013 in docketRJ3-ll, as indicated in item 11 above. See the July 25, 2013 opinion and order indocket R13-ll for additional details on theJCAR suggestions aadthe Board actions with regard to each. One table in that opinion itemizes the changes made inresponse to various suggestions. Another table indicates JCAR suggestions not incorporated into the text, with a brief explanation for each. 13) Willthese amendments replace emergency amendments currently in effect? No.

### Exceptional Events a) Requirements. 1) TheAgency mayrequest USEP A to exclude from use in determinations data showing an exceedance ofanNAAOS that is directlydue to anILLINOIS REGISTER POLLUTION CONTROL BOARD NOTICE OF ADOPTED AMENDMENTS exceptional event. The Agency must demonstrate to USEPA thatthe event caused a soecific air pollution concentration at a particular air qualitv monitming location. 2) A demonstration to justify data exclusion mayinclude any reliable and accurate data, butmustdemonstrate a clear causal relationship between the measured exceedance ofan NAAQS and the event in accordance with subsection (c)(3)(D) ofthis Section. b) Determinations bvUSEPA. USEPA has statedthe criteria for making a detennination to exclude data as follow; 1) Exceptional Events. USEPA has stated that it will exclude data from use in determinations ofexceedance ofan NAAQS where the Agency has demonstrated that an exceptional event caused a specific air pollution concentration in excess ofone or more NAAQS at a particular air qualitv monitoring location. and the Agency otherwise satisfies therequirements of40 CFR 50.14. 2) Fireworks Displays.

USEPA has stated that

### itwill exclude datafrom use in detenninations ofexceedance ofanNAAOS where the Agencyhas demonstrated that emissions from prescribed fires caused a specific air pollution concentration in excess ofone ormoreNAAOS at a particular air quality monitoring location, and the Agency otherwise satisfies the requirements of40 CFR 50.14, provided that the emissions are from prescribed fires that USEPA detennines meets the definition of "exceptional event" in Section 243.I0I. and provided that the Agencyhas certified to USEPA that the Statehas adopted and is implementing aILLINOIS REGISTER POLLUTION CONTROL BOARD NOTICE OF ADOPTED AMENDMENTS Smoke Management Program (SMP) or the State has ensured that the burner emplovedbasic smoke management practices. Ifan exceptional event occurs using the basic smoke management practices aoproach. the Agency must undertake a review ofthe State's approach to ensure public health isbeingprotected and mustinclude consideration ofdevelopment ofan SMP. BOARD NOTE: In each ofcorresponding 40 CFR 50.14(b)(l), {b)(2). and (b)(3), USEP A stated "EPA shall exclude data from use in determinations of exceedances and NAAOS violations." In the first person. "shall" is used more to express present intent or to commit to future action. The Boardhas changed "EPA shall" to "USEPA has stated that itwilL" Further, the Board has relied on the defined term "exceedance ofan NAAOS." c) Schedules and Procedures. !) Public notification. TheAgency or. where the Agencyhas delegated authoritvpursuantto Section 4(g) or Cr) oftheAct. theAgency's delegatee, must notify the publicpromptly whenever an event occurs or is reasonably anticipated to occur tlmt may result in tl1e exceedance ofan NAAQS. 2) Flagging ofData. A) TheAgency mustnotify USEPA ofthe State's intent to exclude one ormore measured exceedances ofan NAAOS as being due to an exceptional event by placing a flag in the appropriate field for the data record ofconcernthat has been submitted to the federal air quality system CAQS) database. B) Flags placed on datainaccordance with this Section must be deemed informational only, and the data must notbe excluded from detetminations with respect to an exceedance ofan NAAQS unless and until USEPA notifies the Agency ofUSEPA concurrence following the Agency's submittal ofa demonstration pursuant to subsection (c)(3) ofthis Section byplacing a concurrence flag

F) USEPA has stated that when USEPA sets a NAAQS for a new pollutant orrevises the NAAQS for an existing pollutant. USEPA mavrevise or set a new schedule for flagging exceptional event data. providing initial data descriptions. and providing detailed data documentation in AOS for the initial designations ofareas for thoseNAAOS. Table A for this Part provides the existing schedule for submission offlags with initial descriptions inAOS and detailed documentation. These schedules apply for those data thatwill or may influence theinitial designation ofareas for those NAAQS. USEPA has stated that itwill revise the table upon which Table A is based as necessary to accommodate revised data submission schedules for new orrevised NAAOS. 3) Submission ofdemonstrations. A) When the Agency has flagged data as being due to an exceptional event and is requesting exclusion ofthe affected measurement data. the Agencymust. after notice and opportunity for public comment. submit a demonstration to USEPA to jnstify data exclusion not later than the sooner ofthree years following the end ofthe calendar quarter in which the flagged concentration was recorded or 12 months priorto the date that a regulatory decision must be madeby USEPA.
