SUPPLEMENTARY INFORMATION:

I. What are the errors being corrected?

This rule corrects errors in the regulatory text designating certain areas for the 2015 ozone NAAQS as provided in the designation rules signed by the EPA Administrator on November 6, 2017 (November 16, 2017; 82 FR 54232), and on April 30, 2018 (June 4, 2018; 83 FR 25776). The EPA is correcting the errors consistent with the rulemaking record. The affected areas are located in California, Illinois, Indiana, Kentucky, Michigan, Montana, Ohio, Pennsylvania and Virginia. The corrections for each state are discussed below and the corrected regulatory text is provided at the end of this action.

California

The EPA is correcting two errors in the regulatory table for California for designations promulgated in the April 30, 2018, ozone designations rule. The EPA is moving the entry for the “Butte County, CA” nonattainment area so that the area will be listed in alphabetical order and, thus, will be listed before the entry for the “Calaveras County, CA” nonattainment area. The EPA is also correcting a typographical error in the entry for the “Pechanga Band of Luiseño Mission Indians of the Pechanga Reservation” nonattainment area by revising “Pu'eskaMountain” to read “Pu'eska Mountain.”

Illinois

The EPA is correcting the regulatory table for Illinois to include McHenry County and Monroe County as attainment/unclassifiable areas. The EPA is adding those counties to the regulatory table, consistent with the rulemaking record for the April 30, 2018, ozone designations rule. The EPA is also moving the entry for “Bond County” so that it will be listed in alphabetical order and, thus, will be listed before the entry for “Boone County.”

McHenry County, Illinois, is part of the Chicago-Naperville, Illinois-Indiana-Wisconsin (IL-IN-WI), Combined Statistical Area (CSA).^[1] The EPA's final Technical Support Document (TSD) for the Chicago-Naperville, IL-IN-WI nonattainment area states that, “EPA's area of analysis is the Chicago-Naperville, IL-IN-WI CSA, which includes the following 19 counties: Bureau, Cook, DeKalb, DuPage, Grundy, Kane, Kankakee, Kendall, Lake, LaSalle, McHenry, Putnam, and Will in Illinois, Jasper, Lake, LaPorte, Newton, and Porter in Indiana, and Kenosha in Wisconsin. The EPA applied the five factors recommended in its guidance to the area of analysis to determine the nonattainment boundary.” In the TSD section, “Conclusion for the Chicago, IL-IN-WI Area,” the EPA identified the portions of Illinois that were being designated as part of the nonattainment area and stated, “All remaining Illinois portions of the Chicago-Naperville, IL-IN-WI CSA are designated consistent with the Illinois' recommendations as attainment/unclassifiable for the 2015 ozone NAAQS: Bureau, DeKalb, Kankakee, LaSalle, McHenry, and Putnam Counties.* * *” The EPA's final TSD for the Chicago-Naperville, IL-IN-WI nonattainment area is located in the docket for the April 30, 2018, designations rule (document number EPA-HQ-OAR-2017-0548-0418) and is the key document setting forth the designations for the Chicago-Naperville, IL-IN-WI CSA.

Monroe County, Illinois, is part of the St. Louis, Missouri-Illinois (MO-IL) Core Based Statistical Area (CBSA). The EPA's final TSD for the St. Louis, MO-IL nonattainment area states, “The EPA believes that using the CBSA ^[2] is an appropriate starting point for the contribution analysis for the St. Louis area to ensure that the nearby areas most likely to contribute to a violating area are evaluated. The area-specific analyses may support nonattainment boundaries that are smaller or larger than the CBSA. The St. Louis CBSA includes the counties of Franklin, Jefferson, Lincoln, St. Charles, and St. Louis, Warren, and the City of St. Louis, in Missouri as well as the counties of Bond, Calhoun, Clinton, Jersey, Macoupin, Madison, Monroe, and St. Clair in Illinois.” In the TSD section, “Conclusion for the St. Louis MO-IL Area,” the EPA identified the portions of Illinois that were being designated as part of the nonattainment area and stated, “The EPA is designating the remaining Franklin County, excluding Boles Township, Jefferson, Lincoln and Warren Counties in Missouri and Bond, Calhoun, Clinton, Jersey, Macoupin and Monroe Counties in Illinois as attainment/unclassifiable for the 2015 ozone NAAQS.” The EPA's final TSD for the St. Louis MO-IL Area nonattainment area is located in the docket for the April 30, 2018, designations rule (document number EPA-HQ-OAR-2017-0548-0416) and is the key document setting forth the designations for the St. Louis CBSA.

Indiana

The EPA is correcting the regulatory table for Indiana to include Scott County, Union County, and Washington County as attainment/unclassifiable areas. The EPA is adding those counties to the regulatory table, consistent with the rulemaking record for the April 30, 2018, ozone designation rule.

Scott County, Indiana, and Washington County, Indiana, are part of the Louisville/Jefferson County—Elizabethtown—Madison, Kentucky-Indiana (KY-IN) CSA. The EPA's final TSD for the Louisville, KY-IN nonattainment area states that, “The area of analysis for the Louisville, KY-IN area included the Louisville/Jefferson County—Elizabethtown—Madison, KY-IN CSA. The Louisville/Jefferson County—Elizabethtown—Madison, KY-IN CSA is comprised of the following counties: Bullitt County (KY); Hardin County (KY); Henry County (KY); Jefferson County (KY); Larue County (KY); Meade County (KY); Nelson County (KY); Oldham County (KY); Shelby County (KY); Spencer County (KY); Trimble County (KY); Clark County (IN); Floyd County (IN); Harrison County (IN); Jefferson County (IN); Scott County (IN); and Washington County (IN). The EPA applied the five factors recommended in its guidance to the area of analysis to determine the nonattainment area boundary.” In the TSD section, “Conclusion for Louisville, KY-IN Area,” the EPA identified the portions of Indiana that were being designated as part of the nonattainment area and stated, “The EPA is not including the remaining analyzed counties within the nonattainment boundary of the Louisville, KY-IN nonattainment area.” The EPA's final TSD for the Louisville, KY-IN nonattainment area is located in the docket for the April 30, 2018, designations rule (document number EPA-HQ-OAR-2017-0548-0396) and is the key document setting forth the designations for the Indiana counties in the Louisville/Jefferson County—Elizabethtown—Madison, KY-IN CSA.

Union County, Indiana is part of the Cincinnati-Wilmington-Maysville, Ohio-Kentucky-Indiana (OH-KY-IN) CSA. The EPA's final TSD for Cincinnati, OH-KY-IN area states that, “For the Cincinnati area, the starting point for the analysis (the area of analysis), is the Cincinnati-Wilmington-Maysville, OH-KY-IN CSA. . . . The Cincinnati-Wilmington-Maysville, OH-KY-IN CSA includes the following counties: Dearborn County (IN), Ohio County (IN), Union County (IN), Boone County (KY), Bracken County (KY), Campbell County (KY), Gallatin County (KY), Grant County (KY), Kenton County (KY), Mason County (KY), Pendleton County (KY), Brown County (OH), Butler County (OH), Clermont County (OH), Clinton County (OH), Hamilton County (OH), and Warren County (OH). The EPA applied the five factors recommended in its guidance to the area of analysis to determine the nonattainment boundary.” In the TSD section, “Conclusion for the Cincinnati Area,” the EPA stated, “The EPA is not modifying the states' recommendations for nonattainment boundaries. Based on the assessment of factors described previously, the EPA has concluded that the following counties or portions of counties meet the CAA criteria for inclusion in the Cincinnati nonattainment area: Butler, Clermont, Hamilton and Warren in Ohio and the parts of Boone, Campbell and Kenton Counties in Kentucky identified in Kentucky's recommendation.” No Indiana counties were included in the Cincinnati nonattainment area. The EPA's final TSD for the Cincinnati, OH-KY-IN nonattainment area is located in the docket for the April 30, 2018, designations rule (document number EPA-HQ-OAR-2017-0548-0397) and is the key document setting forth the designations for the Indiana counties in the Cincinnati-Wilmington-Maysville, OH-KY-IN CSA.

In a letter from the EPA Administrator to the governor of Indiana, sent at the same time the April 30, 2018, rule was signed, the EPA identified the counties the EPA was designating as nonattainment as part of the Chicago, IL-IN-WI and Louisville, KY-IN nonattainment areas and stated that the remaining portions of Indiana, which includes Scott County, Union County and Washington County, were being designated as attainment/unclassifiable.

Kentucky

The EPA is correcting two errors in the regulatory table for Kentucky designations promulgated in the April 30, 2018, ozone designations rule. The EPA is moving the entry for “Mason County” so that it will be listed in alphabetical order and, thus, will be listed before the entry for “Meade County.” The EPA is also correcting a typographical error by revising “Larue County” to read “LaRue County.”

Michigan

The EPA is correcting three errors in the regulatory table for Michigan for designations promulgated in the April 30, 2018, ozone designations rule. In the regulatory table for Michigan, the EPA is correcting a typographical error in the boundary description for the partial Allegan County, Michigan, nonattainment area by revising “Manlus Township” to read “Manlius Township.” The EPA is moving the entry for “Alger County” so that it will be listed in alphabetical order and, thus, will be listed before the entry for “Allegan County (part) remainder.” The EPA is moving the entry for “Sanilac County” so that it will be listed in alphabetical order and, thus, will be listed before the entry for “Schoolcraft County.”

Montana

In the November 6, 2017, designations rule, the EPA regulatory table identified all the counties in Montana as a single statewide attainment/unclassifiable area. The state of Montana subsequently notified the EPA that on September 21, 2016, it had recommended the designations to be on a county-by-county basis rather than as a statewide area. In the preamble for the November 6, 2017, designations rule, the EPA stated, “The EPA is promulgating these designations for 2,649 counties including Indian Country located in those counties, two separate areas of Indian Country, and five territories without notice-and-comment, because we believe that the designations pursuant to this final action are noncontroversial and the designations are consistent with the recommendations of the states and tribes in which these counties and tribal lands are located.” The EPA is correcting the regulatory table for Montana to list each county separately with a designation of attainment/unclassifiable, consistent with Montana's September 21, 2016, recommendation.

Ohio

The EPA is correcting the regulatory table for Ohio to include Carroll County as an attainment/unclassifiable area. The EPA is adding the county to the regulatory table, consistent with the rulemaking record for the April 30, 2018, ozone designation rule.

Carroll County, Ohio, is part of the Cleveland-Akron-Canton, Ohio CSA. The EPA's final TSD for Ohio states that, “For the Cleveland area, the starting point for the area of analysis is the Cleveland-Akron-Canton, Ohio CSA which includes the following counties: Erie, Huron, Lorain, Medina, Summit, Stark, Carroll, Cuyahoga, Lake, Geauga, Portage, Ashtabula, and Tuscarawas.” In the TSD section, “Conclusion for the Cleveland Area,” the EPA stated, “After evaluating the five factors, the EPA is not modifying the State's recommendation and is designating Cuyahoga, Geauga, Lake, Lorain, Medina, Portage, and Summit Counties as the Cleveland nonattainment area for the 2015 ozone NAAQS.” The EPA's final TSD for Ohio is located in the docket for the April 30, 2018, designations rule (document number EPA-HQ-OAR-2017-0548-0381) and is the key document setting forth the designations for the counties in Ohio.

In a letter from the EPA Administrator to the governor of Ohio, sent at the same time the April 30, 2018, rule was signed, the EPA identified the counties the EPA was designating as nonattainment as part of the Cincinnati, OH-KY, Cleveland, Ohio, and Columbus, Ohio nonattainment areas and provided that the remaining portions of Ohio, which includes Carroll County, were being designated as attainment/unclassifiable.

Pennsylvania

In the April 30, 2018, designations rule, the EPA did not include Carbon, Lehigh, Monroe, Northampton and Pike Counties in the designation regulatory table for Pennsylvania. The EPA is adding those counties to the table consistent with the rulemaking record. These five counties are part of the New York-Newark, New York-New Jersey-Connecticut-Pennsylvania (NY-NJ-CT-PA) CSA. The EPA's final TSD for the New York-Northern New Jersey-Long Island, NY-NJ-CT nonattainment area states that the area of analysis is the CSA, with the additional county of Middlesex in Connecticut. The nonattainment area is also referred to as the New York Metro Nonattainment Area. In the final TSD section “Conclusion for The New York Metro Area,” the EPA states, “The counties of Dutchess, Orange, Putnam and Ulster in New York; Carbon, Lehigh, Monroe, Northampton and Pike in Pennsylvania are being excluded from the New York Metro nonattainment area. . . . .” The EPA's final TSD for New York-Northern New Jersey-Long Island, NY-NJ-CT nonattainment area is located in the docket for April 30, 2018, designation rule (document number EPA-HQ-OAR-0548-0411).

In a letter from the EPA Administrator to the governor of Pennsylvania, sent at the same time the April 30, 2018, rule was signed, the EPA summarized the portions of Pennsylvania that the agency was designating. The EPA identified the counties in Pennsylvania that were being designated as nonattainment as part of the Philadelphia-Wilmington-Atlantic City, PA-NJ-MD-DE nonattainment area and provided that the remaining portions of the state, which includes Carbon, Lehigh, Monroe, Northampton and Pike Counties, were being designated as attainment/unclassifiable.

Virginia

In the April 30, 2018, designation rule, the EPA listed two areas out of order in the designation regulatory table for Virginia. To correct the formatting error, the EPA is moving the entries for the “Fredericksburg City” and “Winchester City” attainment/unclassifiable areas to list them alphabetically with the other independent cities that are designated as attainment/unclassifiable. Thus, the “Fredericksburg City” attainment/unclassifiable area will be listed after the entry for “Franklin City” attainment/unclassifiable area and the “Winchester City” attainment/unclassifiable area will be listed after the entry for “Williamsburg City” attainment/unclassifiable area.

II. Statutory and Executive Order Reviews

A. Executive Order 12866: Regulatory Planning and Review and Executive Order 13563: Improving Regulation and Regulatory Review

This action is exempt from review by the OMB because it responds to the CAA requirement to promulgate air quality designations after promulgation of a new or revised NAAQS.

B. Executive Order 13771: Reducing Regulations and Controlling Regulatory Costs

This action is not an Executive Order 13771 regulatory action because actions such as air quality designations associated with a new or revised NAAQS are exempt from review under Executive Order 12866.

C. Paperwork Reduction Act (PRA)

This action does not impose an information collection burden under the PRA. In this action, the EPA is correcting errors in the regulatory text regarding the designation of certain areas for the 2015 ozone NAAQS consistent with the rulemaking record. This action does not contain any information collection activities.

D. Regulatory Flexibility Act (RFA)

This designation action under Clean Air Act (CAA) section 107(d) is not subject to the RFA. The RFA applies only to rules subject to notice-and-comment rulemaking requirements under the Administrative Procedure Act (APA), 5 U.S.C. 553, or any other statute. Section 107(d)(2)(B) of the CAA explicitly provides that designations are exempt from the notice-and-comment provisions of the APA. In addition, designations under CAA section 107(d) are not among the list of actions that are subject to the notice-and-comment rulemaking requirements of CAA section 307(d).

E. Unfunded Mandates Reform Act (UMRA)

This action does not contain any unfunded mandate as described in UMRA, 2 U.S.C. 1531-1538 and does not significantly or uniquely affect small governments. The action imposes no enforceable duty on any state, local or tribal governments or the private sector.

F. Executive Order 13132: Federalism

This action does not have federalism implications. It will not have substantial direct effects on the states, on the relationship between the national government and the states, or on the distribution of power and responsibilities among the various levels of government. The division of responsibility between the federal government and the states for purposes of implementing the NAAQS is established under the CAA.

G. Executive Order 13175: Consultation and Coordination With Indian Tribal Governments

This action does not have tribal implications as specified in Executive Order 13175. This action corrects errors in the regulatory tables in the ozone designation rules signed by the EPA Administrator on November 6, 2017, and April 30, 2018. The corrections are consistent with the rulemaking record. Thus, Executive Order 13175 does not apply.

H. Executive Order 13045: Protection of Children From Environmental Health and Safety Risks

The EPA interprets Executive Order 13045 as applying to those regulatory actions that concern environmental health or safety risks that the EPA has reason to believe may disproportionately affect children, per the definition of “covered regulatory action” in section 2-202 of the Executive Order. This action is not subject to Executive Order 13045 because it does not establish an environmental standard intended to mitigate health or safety risks.

I. Executive Order 13211: Actions That Significantly Affect Energy Supply, Distribution or Use

This action is not subject to Executive Order 13211 because it is not a significant regulatory action under Executive Order 12866.

J. National Technology Transfer and Advancement Act (NTTAA)

This rulemaking does not involve technical standards.

K. Executive Order 12898: Federal Actions To Address Environmental Justice in Minority Populations and Low-Income Populations

This action does not have disproportionately high and adverse human health or environmental effects on minority populations, low-income populations and/or indigenous peoples, as specified in Executive Order 12898 (59 FR 7629, February 16, 1994). This action corrects errors in the regulatory text regarding the designation of certain areas in for the 2015 ozone NAAQS. The corrections are consistent with the rulemaking record for the designation rules signed by the EPA Administrator on November 6, 2017, and April 30, 2018.

L. Congressional Review Act (CRA)

This action is subject to the CRA, and the EPA will submit a rule report to each House of the Congress and to the Comptroller General of the U.S. This action is not a “major rule” as defined by 5 U.S.C. 804(2).
