 Environmental Protection Agency 40 CFR Part 81
[EPA-HQ-OAR-2020-0292; FRL-7822-01-OAR]
RIN 2060-AU79
 AGENCY: Environmental Protection Agency (EPA).
 ACTION: Final rule.
 SUMMARY: The Environmental Protection Agency (EPA) is redesignating the Lancaster County, Nebraska and Milam County, Texas unclassifiable areas initially designated during the EPA's Round 2 air quality designations for the 2010 1-Hour Sulfur Dioxide (SO2) Primary National Ambient Air Quality Standard (NAAQS). Specifically, the EPA now has sufficient information to determine that these unclassifiable areas in Nebraska and Texas are attaining the 2010 1-hour SO2
                         primary NAAQS. Therefore, the EPA is redesignating these areas to attainment/unclassifiable for the 2010 1-hour SO2
                         primary NAAQS. The EPA is also approving these states' requests to redesignate the areas.
 DATES: This final rule is effective on August 16, 2021.

SUPPLEMENTARY INFORMATION: Throughout this document “we,” “us,” or “our” means the EPA. I. Background After the promulgation of a new or revised NAAQS, the EPA is required to designate all areas of the country, pursuant to section 107(d)(1)-(2) of the Clean Air Act (CAA). For the 2010
                    ( print page 37684)
                     1-hour SO2
                     primary NAAQS,[1]
                    
                     designations are based on the EPA's application of the nationwide analytical approach to, and technical assessment of, the weight of evidence for each area, including but not limited to available air quality monitoring data and air quality modeling results. Pursuant to a March 2, 2015, consent decree and court-ordered schedule, the EPA finalized a second set of initial area designations for the 2010 1-hour SO2
                     NAAQS in 2016 (also called, “Round 2”). For the Round 2 designations, the EPA designated the entirety of Lancaster County in Nebraska and the entirety of Milam County in Texas as unclassifiable. The Round 2 intended designations for Lancaster County, Nebraska and Milam County, Texas were published on March 1, 2016. (81 FR 10563). The final designation for Lancaster County, Nebraska published on July 12, 2016. (81 FR 45039). The final designation for Milam County, Texas was published on December 13, 2016, as part of a supplement to the larger Round 2 designation action. (81 FR 89870). Detailed rationale, analyses, and other information supporting the designation for these two areas can be found in the intended and final Round 2 designations' technical support documents for Nebraska and Texas, respectively. These Round 2 documents, along with all other supporting materials for the initial 2010 1-hour SO2
                     primary NAAQS designations for these areas, can be found on the EPA's SO2
                     designations website.[2] On May 6, 2020, Nebraska submitted a letter [3]
                    
                     to the EPA requesting that the entirety of Lancaster County be redesignated to attainment/unclassifiable based on newly available monitoring information, which demonstrates attainment of the 20101-hour SO2
                     NAAQS. On June 26, 2020, Texas submitted a letter [4]
                    
                     to the EPA requesting that the entirety of Milam County be redesignated to attainment/unclassifiable based on newly available monitoring information, which demonstrates attainment of the 2010 1-hour SO2
                     NAAQS. In a notice of proposed rulemaking (NPRM) published on September 2, 2020 (85 FR 54517), the EPA proposed to redesignate to attainment/unclassifiable the unclassifiable portions of Franklin and St. Charles Counties in Missouri; the entirety of Lancaster County in Nebraska; the entirety of Gallia County and the unclassifiable portion of Meigs County in Ohio; and the entirety of Milam County in Texas. As discussed in the NPRM, this final action is based on the currently available monitoring data for two of the areas included in that NPRM that demonstrate attainment of the 2010 1-hour SO2
                     primary NAAQS. Additionally, in that NPRM, the EPA proposed to approve requests for redesignation from the states of Nebraska, Ohio, and Texas for the areas subject to the notice. The 30-day public comment period for the NPRM closed on October 2, 2020. The EPA did not receive any comments specific to the proposed redesignations of Lancaster County in Nebraska and Milam County in Texas. This action only addresses the redesignation of Lancaster County, Nebraska and Milam County, Texas. The areas in Missouri and Ohio received adverse comments and will be addressed in separate rulemaking actions. The details of each state's submittal and the rationale for the EPA's actions are further explained in the NPRM. II. Final Action In this action, the EPA is taking final action to redesignate Lancaster County, Nebraska and Milam County, Texas to attainment/unclassifiable for the 20101-hour SO2
                     primary NAAQS pursuant to CAA section 107(d)(3)(D). The EPA is also taking final action to approve a request for redesignation from unclassifiable to attainment/unclassifiable for the 2010 SO2
                     primary NAAQS from the state of Nebraska dated May 6, 2020, and from the state of Texas dated June 26, 2020. This action changes the legal designation for these areas, found at 40 CFR part 81, from unclassifiable to attainment/unclassifiable for the 2010 1-hour SO2
                     primary NAAQS. III. Environmental Justice Concerns When the EPA establishes a new or revised NAAQS, the CAA requires the EPA to designate all areas of the U.S. as either nonattainment, attainment, or unclassifiable. This action addresses redesignation determinations for two areas for the 2010 SO2
                     NAAQS. Under CAA section 107(d)(3), the redesignation of an area to attainment/unclassifiable is an action that affects the status of a geographical area and does not impose any additional regulatory requirements on sources beyond those imposed by state law. A redesignation to attainment/unclassifiable does not in and of itself create any new requirements. Accordingly, this final action merely redesignates areas to attainment/unclassifiable and does not impose additional requirements. Area redesignations address environmental justice concerns by ensuring that the public is properly informed about the air quality in an area. In locations where air quality does not meet the NAAQS, the CAA requires relevant state authorities to initiate appropriate air quality management actions to ensure that all those residing, working, attending school, or otherwise present in those areas are protected, regardless of minority and economic status. IV. 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 the Office of Management and Budget (OMB) and was, therefore, not submitted to OMB for review. B. Paperwork Reduction Act (PRA) This action does not impose an information collection burden under the PRA. This action is a redesignation of two areas to attainment/unclassifiable is an action that affects the status of a geographical area and does not impose any additional regulatory requirements on sources beyond those imposed by state law. Therefore, this final rulemaking does not impose any new information collection burden under the PRA. C. Regulatory Flexibility Act (RFA) This redesignation action under 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 Procedures Act (APA), 5 U.S.C. 553, or any other statute. Redesignations 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). D. 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.
                    ( print page 37685) E. 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. F. Executive Order 13175: Consultation and Coordination With Indian Tribal Governments This action does not have Tribal implications as specified by Executive Order 13175 (65 FR 67249, November 9, 2000) because no tribal lands are located within the areas covered in this action and the redesignation does not create new requirements. The EPA notes this final redesignation action will not impose substantial direct costs on Tribal governments or preempt Tribal law. G. Executive Order 13045: Protection of Children From Environmental Health and Safety Risks The EPA interprets Executive Order 13045 as applying only 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 concern an environmental health risk or safety risk. H. 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. I. National Technology Transfer and Advancement Act (NTTAA) This rulemaking does not involve technical standards. J. Executive Order 12898: Federal Actions To Address Environmental Justice in Minority Populations and Low-Income Populations The EPA believes that 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). The documentation for this determination is contained in Section III of this preamble, “Environmental Justice Concerns.” K. 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 United States. This action is not a “major rule” as defined by 5 U.S.C. 804(2). L. Judicial Review 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 September 14, 2021. 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 shall not postpone the effectiveness of such rule or action. This action may not be challenged later in proceedings to enforce its requirements.
