SUPPLEMENTARY INFORMATION: Throughout this document whenever “we,” “us,” or “our” is used, we mean EPA. This supplementary information section is arranged as follows: I. Background II. What are the State rule revisions? III. Did the State hold public hearings for these submittals? IV. What is EPA's analysis of the State's submittals? V. What action is EPA taking? VI. Incorporation by Reference VII. Statutory and Executive Order Reviews I. Background Section 109 of the Clean Air Act (CAA) requires EPA to establish national primary (protective of human health) and secondary (protective of human welfare) air quality standards for pollutants for which air quality criteria have been issued under section 108 of the CAA (the criteria pollutants [1]
                    
                    ). Individually and collectively these standards are referred to as NAAQS. Section 109(d)(1) of the CAA requires EPA to review, and if necessary, based on accumulated health and welfare data, to revise each NAAQS every five years. If a NAAQS is revised, states whose rules include state air quality standards may revise their rules to address the revised NAAQS and associated monitoring requirements, and submit them to EPA as SIP revision requests. 
                    *See, e.g.,*
                     415 ILCS 5/10(H). Moreover, section 10(H) of the ILCS requires that Illinois adopt ambient air quality standards that are identical-in-substance to the Federal NAAQS using identical-in-substance rulemaking procedure (415 ILCS 5/10(H)(2016). The Illinois Environmental Protection Agency (IEPA) submitted revisions on ambient air quality standards in the Illinois SIP to EPA for approval on April 2, 2018 and July 26, 2018. Specifically, these SIP revisions update: (1) Illinois ambient air quality definitions and requirements for handling monitoring data influenced by exceptional events, (2) implementation rules for the 2012 primary annual PM2.5
                     NAAQS, and (3) designated reference and equivalent methods for multiple NAAQS. These updates correspond to EPA's rulemakings related to NAAQS that occurred between July 1, 2016 and December 31, 2017. IEPA also submitted a revision to the definitions for VOC in the Illinois SIP to EPA for approval on April 2, 2018. The change included the addition of 1,1,2,2-Tetrafluoro-1-(2,2,2-trifluoroethoxy) ethane to the list of chemical species excluded from the Federal definition of VOC. This update corresponds to EPA's rulemaking related to VOC regulations adopted August 1, 2016. II. What are the State rule revisions? 35 IAC 243.101 Definitions Illinois amended 35 IAC 243.101 to add and revise definitions regarding the exceptional events rule. These definitions were adopted by EPA in “Treatment of Data Influenced by Exceptional Events” (81 FR 68216, October 3, 2016). 35 IAC 243.105 Air Quality Monitoring Data Influenced by Exceptional Events Illinois amended 35 IAC 243.105 to update procedural requirements, requirements for air agency demonstrations, criteria for EPA's approval of the exclusion of event influenced air quality data, and requirements for air agencies to take appropriate and reasonable actions to protect public health from exceedances or violations of the NAAQS. 
                    ( print page 65538)
                    Additionally, Illinois repealed Section 243.TABLE A “Schedule for Submission for Data Influenced by Exceptional Events for Use in Initial Area Designations.” EPA revised the requirements for handling monitoring data influenced by exceptional events (81 FR 68216, October 3, 2016). EPA recognizes that basing regulatory determinations on data influenced by exceptional events may not be appropriate in some instances. The rules provide a procedure for exclusion of data influenced by exceptional events from regulatory decision-making. An exceptional event has a clear relationship with violation of NAAQS, is not reasonably controlled or preventable, unlikely to reoccur at a particular location, and has been declared such by EPA. The revisions require written mitigation plans for areas that have “historically documented” or “known seasonal” exceptional events. Several revisions relate to wildfires and controlled burns as exceptional events. 35 IAC 243.108 Incorporations by Reference Illinois revised this section to incorporate by reference EPA's updated “List of Designated Reference and Equivalent Methods” from January 1, 2016, to December 31, 2017. EPA issued updated versions of the “List of Designated Reference and Equivalent Methods” that included new Federal Equivalent Methods (FEMs) and Federal Reference Methods (FRMs) for monitoring of Carbon Monoxide (CO), oxides of nitrogen (NOX), and PM2.5. See 82 FR 14325 (March 20, 2017), 82 FR 21995 (May 11, 2017) 82 FR 44612 (September 25, 2017), 82 FR 45842 (October 2, 2017). The list with all approved FEMs and FRMs is located at: 
                    *https://www3.epa.gov/​ttn/​amtic/​criteria.html.* Illinois also added a statement to 35 IAC 243.108 that the incorporation by reference of EPA's promulgated monitoring methods “includes the following USEPA methods designations that occurred after December 16, 2017.” Additionally, Illinois updated 35 IAC 243.108 to incorporate by reference the 2017 versions of appendices A-1, A-2, B, C, D, F, G, H, I, J, K, L, N, O, P, Q, R, S, T and U of 40 CFR part 50. These appendices contain the reference monitoring methods for and the “interpretation” of (
                    *i.e.,*
                     data handling conventions and computations) the ambient standards for the criteria air pollutants. EPA made one change in the 2017 versions of these appendices relative to the 2016 versions. EPA revised the appendix N “Interpretation of the Primary and Secondary National Ambient Air Quality Standards for Particulate Matter.” These revisions address a number of important attainment planning issues including the process for determining control strategies, including Reasonably Available Control Measures/Reasonably Available Control Technology (RACM/RACT) for Moderate areas; and Best Available Control Measures/Best Available Control Technology (BACM/BACT) and Most Stringent Measures (MSM) for Serious areas; guidelines for attainment demonstrations for areas that can attain by the statutory attainment date, and “impracticability” demonstrations for areas that cannot practicably attain by the statutory attainment date; contingency measures for areas that fail to meet RFP or fail to attain the NAAQS by the attainment date; and codification of the clean data policy for PM2.5
                     NAAQS nonattainment areas. These implementation rules also clarify the specific attainment planning requirements that apply to PM2.5
                     NAAQS nonattainment areas based on their classification (either Moderate or Serious), and the process for reclassifying Moderate areas to Serious. In addition, the updated implementation rules revoke older 1997 annual NAAQS for PM2.5, which will no longer apply in areas designated as attainment for that standard. For areas that EPA designated as nonattainment for the 1997 standard, the 1997 primary annual NAAQS for PM2.5
                     will continue to apply until the effective date of an EPA designation of attainment for the area. Illinois' rule revisions incorporate by reference these amended CFR appendices. 35 IAC 243.120 PM*10*
                     and PM*2.5* Illinois amended 35 IAC 243.120 to include the revocation language for 1997 PM2.5
                     NAAQS. As stated above, the 1997 PM2.5
                     NAAQS standard no longer applies to any area that is in attainment of the 1997 PM2.5
                     standard 82 FR 14325 (August 24, 2016). In Illinois all areas are designated attainment or attainment/unclassifiable for the 1997 PM2.5
                     NAAQS except the Metro East St. Louis nonattainment area. These area are Madison, Monroe, and St. Clair Counties and the Baldwin Village area of Randolph County (40 CFR 81.214, 2016). 35 IAC 211.7150 Volatile Organic Material (VOM) or Volatile Organic Compound (VOC) Illinois amended 35 IAC 211.7150 to incorporate a change to the list of chemical species excluded from the Federal definition of VOC (81 FR 50330, August 1, 2016). The change included the addition of 1,1,2,2-Tetrafluoro-1-(2,2,2-trifluoroethoxy) ethane to the list of chemical species excluded from the Federal definition of VOC. In 2007, EPA received a petition requesting that 1,1,2,2-Tetrafluoro-1-(2,2,2-trifluoroethoxy) ethane be exempted from VOC control based on its lower reactivity than ethane and that it is not expected to contribute to the depletion of the stratospheric O3
                     layer. On August 1, 2016 (81 FR 50330), EPA responded to the petition by amending 40 CFR 51.100(s) to exclude this chemical compound from the definition of VOC for purposes of preparing SIPs to attain the ozone NAAQS under title I of the CAA (78 FR 9823). Based on the mass maximum incremental reactivity value for the compound being equal to or less than that of ethane, EPA concluded that this compound makes negligible contributions to tropospheric ozone formation (81 FR 50330). EPA's action became effective August 1, 2016. IEPA's SIP revision to the Illinois definition of VOM is consistent with EPA's action amending the definition of VOC at 40 CFR 51.100(s). III. Did the State hold public hearings for these submittals? Illinois held public hearings for the NAAQS updates on September 21, 2017 and April 12, 2018. The public hearing held on September 21, 2017 addressed NAAQS updates regarding updated definitions and requirements for handling monitoring data influenced by exceptional events, implementation rules for the 2012 primary annual NAAQS for PM2.5, maintenance of primary and secondary NAAQS for lead without revision, addition of EPA-promulgated monitoring methods for multiple NAAQS, and an adoption of a correction to an equation used for calculating PM2.5
                     compliance. One comment addressed concern of error in placement of language in the implementation rule for the 2012 PM2.5
                     as stated in EPA regulations. EPA indicated that the placement of language in the Federal regulations was not in error and no further action was taken. The public hearing held on April 12, 2018 addressed the NAAQS updates regarding the addition of EPA-promulgated monitoring methods for multiple NAAQS and updated List of 
                    ( print page 65539)
                    Designated Reference and Equivalent Methods. No adverse comments were received. Illinois held a public hearing for the VOM updates regarding the request of 1,1,2,2-Tetrafluoro-1-(2,2,2-trifluoroethoxy) ethane being exempted from VOC regulations on September 21, 2017. No adverse comments were received. IV. What is EPA's analysis of the State's submittals? EPA finds the state's requested SIP revisions to be approvable, because the state's rule revisions make the state's air quality standards and associated monitoring requirements identical-in-substance to EPA's promulgated NAAQS and VOC updates. V. What action is EPA taking? EPA is approving NAAQS updates into the Illinois SIP to 35 IAC 243.101, 35 IAC 234.105, 35 IAC 243.108, 35 IAC 243.120 35, and removal of IAC 243.TABLE A contained in the April 2, 2018 submittal and the July 26, 2018 submittal. EPA is approving VOC updates into the Illinois SIP to 35 IAC 211.7150 contained in the April 2, 2018 submittal. EPA is also removing an incorrect reference in 40 CFR 52.720(b)(3) on how copies of materials incorporated by reference may be inspected. We are publishing this action without prior proposal because we view this as a noncontroversial amendment and anticipate no adverse comments. However, in the proposed rules section of this 
                    **Federal Register**
                     publication, we are publishing a separate document that will serve as the proposal to approve the state plan if relevant adverse written comments are filed. This rule will be effective February 19, 2019 without further notice unless we receive relevant adverse written comments by January 22, 2019. If we receive such comments, we will withdraw this action before the effective date by publishing a subsequent document that will withdraw the final action. All public comments received will then be addressed in a subsequent final rule based on the proposed action. EPA will not institute a second comment period. Any parties interested in commenting on this action should do so at this time. Please note that if EPA receives adverse comment on an amendment, paragraph, or section of this rule and if that provision may be severed from the remainder of the rule, EPA may adopt as final those provisions of the rule that are not the subject of an adverse comment. If we do not receive any comments, this action will be effective February 19, 2019. VI. Incorporation by Reference In this rule, EPA is finalizing regulatory text that includes incorporation by reference. In accordance with requirements of 1 CFR 51.5, EPA is finalizing the incorporation by reference of the Illinois Regulations described in the amendments to 40 CFR part 52 set forth below. EPA has made, and will continue to make, these documents generally available through 
                    *www.regulations.gov*
                     and at the EPA Region 5 Office (please contact the person identified in the 
                    **For Further Information Contact**
                     section of this preamble for more information). Therefore, these materials have been approved by EPA for inclusion in the State implementation plan, have been incorporated by reference by EPA into that plan, are fully federally enforceable under sections 110 and 113 of the CAA as of the effective date of the final rulemaking of EPA's approval, and will be incorporated by reference in the next update to the SIP compilation.[2] VII. Statutory and Executive Order Reviews Under the CAA, the Administrator is required to approve a SIP submission that complies with the provisions of the CAA and applicable Federal regulations. 42 U.S.C. 7410(k); 40 CFR 52.02(a). Thus, in reviewing SIP submissions, EPA's role is to approve state choices, provided that they meet the criteria of the CAA. Accordingly, this action merely approves state law as meeting Federal requirements and does not impose additional requirements beyond those imposed by state law. For that reason, this action: Is not a significant regulatory action subject to review by the Office of Management and Budget under Executive Orders 12866 (58 FR 51735, October 4, 1993) and 13563 (76 FR 3821, January 21, 2011);
                Is not anExecutive Order 13771 (82 FR 9339, February 2, 2017) regulatory action because SIP approvals are exempted under Executive Order 12866.
                Does not impose an information collection burden under the provisions of the Paperwork Reduction Act (44 U.S.C. 3501 
                    *et seq.*);
                Is certified as not having a significant economic impact on a substantial number of small entities under the Regulatory Flexibility Act (5 U.S.C. 601 
                    *et seq.*);
                Does not contain any unfunded mandate or significantly or uniquely affect small governments, as described in the Unfunded Mandates Reform Act of 1995 (Pub. L. 104-4);
                Does not have Federalism implications as specified inExecutive Order 13132 (64 FR 43255, August 10, 1999);
                Is not an economically significant regulatory action based on health or safety risks subject toExecutive Order 13045 (62 FR 19885, April 23, 1997);
                Is not a significant regulatory action subject toExecutive Order 13211 (66 FR 28355, May 22, 2001);
                Is not subject to requirements of Section 12(d) of the National Technology Transfer and Advancement Act of 1995 (15 U.S.C. 272 note) because application of those requirements would be inconsistent with the CAA; and
                Does not provide EPA with the discretionary authority to address, as appropriate, disproportionate human health or environmental effects, using practicable and legally permissible methods, underExecutive Order 12898 (59 FR 7629, February 16, 1994). In addition, the SIP is not approved to apply on any Indian reservation land or in any other area where EPA or an Indian tribe has demonstrated that a tribe has jurisdiction. In those areas of Indian country, the rule does not have tribal implications and will not impose substantial direct costs on tribal governments or preempt tribal law as specified by Executive Order 13175 (65 FR 67249, November 9, 2000). The Congressional Review Act, 5 U.S.C. 801 
                    *et seq.,*
                     as added by the Small Business Regulatory Enforcement Fairness Act of 1996, generally provides that before a rule may take effect, the agency promulgating the rule must submit a rule report, which includes a copy of the rule, to each House of the Congress and to the Comptroller General of the United States. EPA will submit a report containing this action and other required information to the U.S. Senate, the U.S. House of Representatives, and the Comptroller General of the United States prior to publication of the rule in the 
                    **Federal Register**
                    . A major rule cannot take effect until 60 days after it is published in the 
                    **Federal Register**
                    . This action is not a “major rule” as defined by 5 U.S.C. 804(2). Under section 307(b)(1) of the CAA, petitions for judicial review of this action must be filed in the United States Court of Appeals for the appropriate circuit by February 19, 2019. Filing a petition for reconsideration by the Administrator of this final rule does not affect the finality of this action for the purposes of judicial review nor does it extend the time within which a petition for judicial review may be filed, and 
                    ( print page 65540)
                    shall not postpone the effectiveness of such rule or action. Parties with objections to this direct final rule are encouraged to file a comment in response to the parallel notice of proposed rulemaking for this action published in the proposed rules section of today's 
                    **Federal Register**
                    , rather than file an immediate petition for judicial review of this direct final rule, so that EPA can withdraw this direct final rule and address the comment in the proposed rulemaking. This action may not be challenged later in proceedings to enforce its requirements. (See section 307(b)(2) of the CAA.) List of Subjects in 40 CFR Part 52 Environmental protection

                         The criteria pollutants are ozone (O3), nitrogen oxides (represented by nitrogen dioxide (NO2)), sulfur oxides (represented by sulfur dioxide (SO2)), carbon monoxide (CO), particulate matter (represented by total suspended particulates (TSP), particulates (PM10), and fine particulates (PM2.5)), and lead (Pb). Note that Illinois also has air quality standard and monitoring rules for “coarse particulate matter” (PM2.5-10), although this is not a criteria pollutant and is generally considered to be included in PM10.
