The Environmental Protection Agency (EPA) is approving, under the Clean Air Act (CAA), revisions to the sulfur dioxide (SO<INF>2</INF>) portion of the Indiana State Implementation Plan (SIP). The state of Indiana is requesting revisions to emission limits at the Northern Indiana Public Service Company Bailly Station (NIPSCO) facility reflecting permanently shut down units. Indiana is also requesting SIP revisions for two facilities formerly owned by ArcelorMittal USA LLC and currently owned by Cleveland-Cliffs LLC (the Indiana Harbor East and Indiana Harbor West facilities). The Indiana Harbor East facility is required to demonstrate continuous compliance with final SO<INF>2</INF> emission limits as a daily (24-hour) average. These revisions will result in decreases in allowable SO<INF>2</INF> emissions at all three facilities, maintaining SO<INF>2</INF> attainment/unclassifiable designations for the 2010 1-hour SO<INF>2</INF> national ambient air quality standards (NAAQS). EPA proposed to approve this action on June 26, 2023, and received no adverse comments.

The Environmental Protection Agency (EPA) is proposing amendments to the National Emissions Standards for Hazardous Air Pollutants (NESHAP) for Coke Ovens: Pushing, Quenching, and Battery Stacks (PQBS) source category, and the NESHAP for the Coke Oven Batteries (COB) source category. This proposal presents the results of the residual risk and technology review (RTR) conducted as required under the Clean Air Act (CAA) for the PQBS source category, and the periodic technology review for the COB source category, also required under the CAA. The EPA is proposing that risks due to emissions of hazardous air pollutants (HAP) from the PQBS source category are acceptable and that the current NESHAP provides an ample margin of safety to protect public health. Under the technology review for PQBS NESHAP, we are proposing there are no developments in practices, processes or control technologies that necessitate revision of standards for this source category. Under the technology review for the COB source category, the EPA is proposing amendments to the NESHAP to lower the limits for leaks from doors, lids, and offtakes to reflect improvements in technology to minimize emissions. We also are proposing a requirement for fenceline monitoring for benzene (as a surrogate for coke oven emissions) and a requirement to conduct root cause analysis and corrective action upon exceeding an action level. In addition, we are proposing: (1) new standards for several unregulated HAP or sources of HAP at facilities subject to PQBS NESHAP; (2) the removal of exemptions for periods of startup, shutdown, and malfunction consistent with a 2008 court decision, and clarifying that the standards apply at all times for both source categories; and (3) the addition of electronic reporting for performance test results and compliance reports. We solicit comments on all aspects of this proposed action.

The EPA is taking this action pursuant to the CAA.

Under the Clean Air Act (CAA), the Environmental Protection Agency (EPA) is proposing to approve a May 12, 2022, State Implementation Plan (SIP) submittal from the Ohio Environmental Protection Agency (OEPA). This SIP submittal consists of a source- specific limitation for certain process lines at Forest City Technologies, Plant 4, in Wellington, Ohio. The source-specific limitation reflects the lowest rate possible for the facility given technological and cost considerations. The source-specific limitation is established through the Ohio SIP, per the Ohio Administrative Code (OAC), and listed as an enforceable condition in the facility's operating permit, issued by OEPA on June 23, 2020.

The Environmental Protection Agency (EPA) is announcing a public webinar on the new regulatory provisions of the Renewable Fuel Standard (RFS) program.

The Environmental Protection Agency (EPA) is proposing to approve a portion of a State Implementation Plan (SIP) revision submitted by the Florida Department of Environmental Protection (FDEP) on April 1, 2022, for the purpose of removing several rules from the Florida SIP. EPA is proposing to remove the State's Clean Air Interstate Rule (CAIR) rules from the Florida SIP as well as several Reasonably Available Control Technology (RACT) rules for particulate matter (PM) because these rules have become obsolete. The State has provided a non-interference demonstration to support the removal of these rules from the Florida SIP pursuant to the Clean Air Act (CAA or Act).

The Environmental Protection Agency (EPA) is approving Washington State Implementation Plan (SIP) revisions submitted on August 10, 2022. The submitted revisions incorporate the most recent updates to Washington's Smoke Management Plan and reflect state legislative and regulatory changes. The EPA is approving the revisions based on our determination that the revisions are consistent with Clean Air Act requirements.

The Environmental Protection Agency (EPA) is approving a revision to the Alaska State Implementation Plan (SIP) submitted on May 16, 2022. In the submission, Alaska revised and repealed State regulations originally put in place to limit water vapor emissions that may contribute to ice fog and to address the use of high-sulfur marine fuels near the communities of St. Paul Island and Unalaska. Alaska determined that the regulations are obsolete due to technology improvements and regulatory changes, including Federal sulfur content in fuel restrictions. The State requested that the SIP be updated to reflect the revised and repealed State regulations. We have determined the submitted revision will not interfere with attainment of the national ambient air quality standards or other applicable requirements of the Clean Air Act.

The Environmental Protection Agency (EPA) is approving a State Implementation Plan (SIP) revision submitted by the North Carolina Department of Environmental Quality (NCDEQ), Division of Air Quality (DAQ), via a letter dated April 13, 2021.

The Environmental Protection Agency (EPA) is approving Tennessee's July 31, 2019, State Implementation Plan (SIP) submission pertaining to the ``good neighbor'' provision of the Clean Air Act (CAA or Act) for the 2010 1-hour sulfur dioxide (SO<INF>2</INF>) National Ambient Air Quality Standard (NAAQS). The good neighbor provision requires each State's implementation plan to contain adequate provisions prohibiting the interstate transport of air pollution in amounts that will contribute significantly to nonattainment, or interfere with maintenance, of a NAAQS in any other State. EPA has determined that Tennessee will not contribute significantly to nonattainment or interfere with maintenance of the 2010 1-hour SO<INF>2</INF> NAAQS in any other State. Therefore, EPA is approving the July 31, 2019, SIP revision as meeting the requirements of the good neighbor provision for the 2010 1-hour SO<INF>2</INF> NAAQS.

This action proposes changes to the EPA's Air Emissions Reporting Requirements (AERR). The proposed amendments may require changes to current regulations of State, local, and certain tribal air agencies; would require these agencies to report emissions data to the EPA using different approaches from current requirements; and would require owners/operators of some facilities to report additional emissions data. More specifically, the EPA is proposing to require certain sources report information regarding emission of hazardous air pollutants (HAP); certain sources to report criteria air pollutants, their precursors and HAP; and to require State, local, and certain tribal air agencies to report prescribed fire data. The proposed revisions would also define a new approach for optional collection by air agencies of such information on HAP by which State, local and certain tribal air agencies may implement requirements and report emissions on behalf of owners/operators. The proposed revisions would also make the requirements for point sources consistent for every year; phase in earlier deadlines for point source reporting; and add requirements for reporting fuel use data for certain sources of electrical generation associated with peak electricity demand. The proposed revisions include further changes for reporting on airports, rail yards, commercial marine vessels, locomotives, and nonpoint sources. For owners/operators of facilities that meet criteria described in this proposal, the proposed revisions would require reporting of performance test and performance evaluation data to the EPA for all tests conducted after the effective date provided in the final rulemaking. The EPA also proposes to clarify that information the EPA collects through the AERR is emission data that is not subject to confidential treatment.

The Environmental Protection Agency (EPA) is planning to submit an information collection request (ICR), ``Transportation Conformity Determinations for Federally Funded and Approved Transportation Plans, Programs, and Projects'' (EPA ICR No. 2130.07, OMB Control No. 2060-0561), to the Office of Management and Budget (OMB) for review and approval in accordance with the Paperwork Reduction Act. Before doing so, EPA is soliciting public comments on specific aspects of the proposed information collection as described below. This is a proposed extension of the ICR, which is currently approved through February 29, 2024.

The Environmental Protection Agency (EPA) is finalizing the approval of a State Implementation Plan (SIP) revision to the North Carolina SIP, submitted by the State of North Carolina through the North Carolina Department of Environmental Quality (NCDEQ), Division of Air Quality (NCDAQ), via a letter dated April 13, 2021. This SIP revision updates several NCDEQ air regulations which apply to sources that emit volatile organic compounds (VOC).

In this notice, the Environmental Protection Agency (EPA) is notifying the public that it has found that the 2023 motor vehicle emissions budgets (MVEBs) for volatile organic compounds (VOCs) and nitrogen oxides (NO<INF>X</INF>), submitted by the Maryland Department of the Environment (MDE) on March 7, 2023, for the 2015 8-hour ozone national ambient air quality standard (NAAQS), are adequate for transportation conformity purposes for the Baltimore 2015 8-hour ozone moderate nonattainment area. As a result of EPA's finding, the State of Maryland must use the MVEBs from the March 7, 2023, attainment demonstration for future conformity determinations for the 2015 8-hour ozone standard.

The Environmental Protection Agency (EPA) is approving changes to the Georgia State Implementation Plan (SIP), submitted by the State of Georgia through the Georgia Environmental Protection Division (GA EPD) via a letter dated November 4, 2021. The SIP revision revises Georgia's Stage I vapor recovery rules primarily by removing outdated references and making several clarifying edits. The revision also updates several definitions and makes two substantive changes. EPA is approving these changes pursuant to the Clean Air Act (CAA or Act).

The Environmental Protection Agency (EPA) has submitted an information collection request (ICR), ``Ambient Air Quality Surveillance (EPA ICR Number 0940.30, OMB Control Number 2060-0084) to the Office of Management and Budget (OMB) for review and approval in accordance with the Paperwork Reduction Act. This is a proposed extension of the ICR, which is currently approved through July 31, 2023. Public comments were previously requested via the Federal Register on February 17, 2023, during a 60-day comment period. This notice allows for an additional 30 days for public comments. This notice allows for an additional 30 days for public comments.

Addressing childhood lead exposure is a priority for the Environmental Protection Agency (EPA). This rule addresses health concerns for all affected communities, including children living in communities with environmental justice concerns, who have significantly higher blood lead levels (BLLs) than other children. As part of EPA's efforts to reduce childhood lead exposure, and in accordance with a U.S. Court of Appeals for the Ninth Circuit 2021 opinion, EPA is proposing to lower the dust-lead hazard standards (DLHS) from 10 micrograms per square foot ([micro]g/ft\2\) and 100 [micro]g/ft\2\ for floors and window sills to any reportable level as analyzed by a laboratory recognized by EPA's National Lead Laboratory Accreditation Program. This is a non-numeric value that the Agency refers to as greater than zero [micro]g/ft\2\ and may vary based on laboratory or test. While EPA's DLHS do not compel property owners or occupants to evaluate their property for lead-based paint (LBP) hazards nor take control actions, if an LBP activity such as an abatement is performed, then EPA's regulations set requirements for doing so. EPA is also proposing to change the dust-lead clearance levels (DLCL), which are the values used to determine when abatement work can be considered complete, from 10 [micro]g/ft\2\, 100 [micro]g/ft\2\ and 400 [micro]g/ ft\2\ for floors, window sills, and window troughs to 3 [micro]g/ft\2\, 20 [micro]g/ft\2\, and 25 [micro]g/ft\2\, respectively. Under this proposal, the DLHS for floors and window sills would not be the same as the DLCL for floors and window sills (i.e., the DLHS and DLCL would be decoupled). Accordingly, dust-lead hazards could remain after an abatement due to the different statutory direction that Congress provided EPA with respect to the DLCL. Additionally, EPA is proposing to change the definition of abatement so that the recommendation for action applies when dust-lead loadings are at or above the DLCL, as well as several other amendments, including revising the definition of target housing to conform with the statute.

The Environmental Protection Agency (EPA) is taking interim final action to stay, for emissions sources in Arkansas, Kentucky, Louisiana, Mississippi, Missouri, and Texas only, the effectiveness of the federal implementation plan (FIP) requirements established to address the obligations of these and other states to mitigate interstate air pollution with respect to the 2015 national ambient air quality standards (NAAQS) for ozone (the Good Neighbor Plan). The EPA is also revising certain other regulations to ensure that sources in these states will continue to be subject to previously established requirements to mitigate interstate air pollution with respect to other ozone NAAQS while the Good Neighbor Plan's requirements are stayed. These revisions will also ensure that the stay is limited to requirements for which the EPA does not currently have authority to implement a FIP pending judicial review. The stay and the associated revisions to other regulations are being issued in response to judicial orders that partially stay, pending judicial review, a separate, earlier EPA action which disapproved certain state implementation plan (SIP) revisions submitted by these and other states. Finally, for states for which the Good Neighbor Plan's requirements are not being stayed, the EPA is revising three near-term deadlines that are incorrect as published in the Good Neighbor Plan.

On September 21, 2022, the Commonwealth of Kentucky, through the Kentucky Energy and Environment Cabinet (Cabinet), Division of Air Quality (DAQ), submitted a request for the Environmental Protection Agency (EPA) to redesignate the Northern Kentucky portion (hereinafter referred to as the ``Northern Kentucky Area'' or ``Area'') of the Cincinnati, Ohio- Kentucky, 2015 8-hour ozone nonattainment area (hereinafter referred to as the ``Cincinnati OH-KY Area'') to attainment for the 2015 8-hour ozone National Ambient Air Quality Standards (NAAQS or standards) and to approve a State Implementation Plan (SIP) revision containing a maintenance plan for the Area. The Cabinet submitted this request and SIP revision through a letter dated September 20, 2022, and supplemented it on November 22, 2022. EPA is proposing to approve the Commonwealth's plan for maintaining attainment of the 2015 8-hour ozone standard in the Northern Kentucky Area, including the motor vehicle emission budgets (MVEBs) for nitrogen oxides (NO<INF>X</INF>) and volatile organic compounds (VOCs) for the years of 2026 and 2035 for the Area, to incorporate the maintenance plan into the SIP, and to redesignate the Area to attainment for the 2015 8-hour ozone NAAQS. EPA previously approved the redesignation request and maintenance plan for the Ohio portion of the Cincinnati, OH-KY Area. EPA is also notifying the public of the status of EPA's adequacy determination for the MVEBs for the Area.

The Environmental Protection Agency (EPA) is proposing under the Clean Air Act (CAA or ``Act'') to approve a revision to the San Francisco Bay Area portion of the California State Implementation Plan (SIP). This revision consists of updated transportation conformity procedures related to the interagency coordination on project-level conformity and exchange of travel data for emissions inventories developed for air quality plans and regional transportation conformity analyses. The intended effect is to update the transportation conformity criteria and procedures in the California SIP.

The Environmental Protection Agency (EPA) is finalizing reporting and recordkeeping requirements for asbestos under the Toxic Substances Control Act (TSCA). EPA is requiring certain persons who manufactured (including imported) or processed asbestos and asbestos- containing articles, including as an impurity, in the four years prior to the date of publication of this final rule to electronically report certain exposure-related information. This action results in a one-time reporting requirement. EPA emphasizes that this requirement includes asbestos that is a component of a mixture. The information sought includes presence, types, and quantities of asbestos (including asbestos that is a component of a mixture) and asbestos-containing articles that were manufactured (including imported) or processed, types of use, and employee data. EPA and other Federal agencies will use reported information in considering potential future actions, including risk evaluation and risk management activities.

The Environmental Protection Agency (EPA) is proposing to approve a State Implementation Plan (SIP) revision submitted by the Illinois Environmental Protection Agency (IEPA or Illinois). The revision, submitted on July 8, 2022, incorporates revisions to the Illinois air pollution control rules entitled ``Part 243--Ambient Air Quality Standards'' and also updates the ``List of Designated Reference and Equivalent Methods'' in response to EPA rulemakings and changes to the National Ambient Air Quality Standards (NAAQS) that EPA adopted in 2021.

The Environmental Protection Agency (EPA) is approving a revision to the Wisconsin state implementation plan (SIP) revising air emissions reporting requirements codified in Chapter 438 of the Wisconsin Administrative Code (Wis. Admin. Code). Additionally, EPA is approving a related infrastructure requirement under section 110 of the Clean Air Act (CAA) for the 2012 fine particulate matter (PM<INF>2.5</INF>) and 2015 ozone National Ambient Air Quality Standards (NAAQS). The infrastructure requirements are designed to ensure that the structural components of each state's air quality management program are adequate to meet the state's responsibilities under the CAA. EPA proposed to approve this action on March 23, 2023, and received no adverse comments.

Pursuant to the Federal Clean Air Act (CAA or Act), the Environmental Protection Agency (EPA) is proposing to approve two revisions to the Arkansas State Implementation Plan (SIP) submitted by the Governor of the State of Arkansas on May 12, 2022, and November 1, 2022. The revisions were submitted in response to a finding of substantial inadequacy and SIP call published by EPA on June 12, 2015, which included certain provisions in the Arkansas SIP related to excess emissions during startup, shutdown, and malfunction (SSM) events. The submittals request the removal of the provisions identified in the 2015 SIP call from the Arkansas SIP. EPA is proposing to determine that the removal of these substantially inadequate provisions from the SIP will correct the deficiencies in the Arkansas SIP identified in the June 12, 2015 SIP call.

The Environmental Protection Agency (EPA) is removing the ``emergency'' affirmative defense provisions from the EPA's title V operating permit program regulations. These provisions established an affirmative defense that sources could have asserted in enforcement cases brought for noncompliance with technology-based emission limitations in operating permits, provided that the exceedances occurred due to qualifying emergency circumstances. These provisions, which have never been required elements of state operating permit programs, are being removed because they are inconsistent with the EPA's interpretation of the enforcement structure of the Clean Air Act (CAA or the Act) in light of prior court decisions from the U.S. Court of Appeals for the D.C. Circuit. The removal of these provisions is also consistent with other recent EPA actions involving affirmative defenses and would harmonize the EPA's treatment of affirmative defenses across different CAA programs. Through this document, the EPA is also providing guidance on the implementation process resulting from the removal of the emergency affirmative defense provisions from the EPA's regulations, including the need for some state, local, and tribal permitting authorities to submit program revisions to the EPA to remove similar title V affirmative defense provisions from their EPA-approved title V programs, and to remove similar provisions from individual operating permits.

The Environmental Protection Agency (EPA) is proposing a limited approval and limited disapproval of revisions to the Mojave Desert Air Quality Management District (MDAQMD or ``the District'') portion of the California State Implementation Plan (SIP). This revision concerns particulate matter (PM) emissions from all sources of air pollution emissions in the District. We are proposing action on a local rule that regulates these emission sources under the Clean Air Act (CAA or ``the Act''). We are taking comments on this proposal and plan to follow with a final action.

The Environmental Protection Agency (EPA) is proposing to approve a revised definition in the State Implementation Plan (SIP) and the Title V Operating Permit Program for the State of Connecticut. On June 9, 2023, the Connecticut Department of Energy and Environmental Protection (CT DEEP) submitted to EPA a request to parallel process recently proposed revisions to the state's definition of ``severe non- attainment area for ozone'' for inclusion in the EPA-approved SIP and Title V Operating Permit Program. The revision is necessary to fully implement these programs based on a nonattainment reclassification to a portion of Connecticut for the 2008 ozone National Ambient Air Quality Standard. EPA is approving these revisions pursuant to the CAA and implementing federal regulations.

In accordance with the Clean Air Act, as amended (CAA or the Act), notice is given of a proposed consent decree in Sierra Club v. U.S. EPA, et al., No. 3:23-cv-00780-TLT. On February 22, 2023, Plaintiff Sierra Club filed a complaint in the United States District Court for the Northern District of California Oakland Division, alleging that the Environmental Protection Agency (EPA or the Agency) failed to perform certain non-discretionary duties in accordance with the Act to promulgate a Federal implementation plan (FIP) within two years of finding that Texas failed to submit a state implementation plan (SIP) for the Rusk/Panola 2010 SO<INF>2</INF> National Ambient Air Quality Standard (SO<INF>2</INF> NAAQS) nonattainment area. EPA is providing notice of this proposed consent decree, which would resolve all claims in the case by establishing a deadline for EPA to take final action as specified in the decree.

On June 13, 2023, the Environmental Protection Agency (EPA) proposed a rule titled ``Air Plan Approval; Revision to Air Pollution Control Rules'' to approve revisions to the State Implementation Plan (SIP) for Oklahoma submitted by the State of Oklahoma on January 30, 2023. The EPA is extending the comment period on this proposed rule that currently closes on July 13, 2023, to allow additional time for stakeholders to review and comment on the proposal.

The Environmental Protection Agency (EPA) is finalizing the rescission of the rule entitled, ``Increasing Consistency and Transparency in Considering Benefits and Costs in the Clean Air Act Rulemaking Process'' (hereinafter, the ``Benefit-Cost Rule''). The EPA is rescinding the rule because the changes advanced by the rule were inadvisable, untethered to the Clean Air Act (CAA), and not necessary to effectuate the purposes of the Act.

Under the Clean Air Act, the Environmental Protection Agency (EPA) is required to determine the applicable volume requirements for the Renewable Fuel Standard (RFS) for years after those specified in the statute. This action establishes the applicable volumes and percentage standards for 2023 through 2025 for cellulosic biofuel, biomass-based diesel, advanced biofuel, and total renewable fuel. This action also establishes the second supplemental standard addressing the judicial remand of the 2016 standard-setting rulemaking. Finally, this action makes several regulatory changes to the RFS program, including changes related to the treatment of biogas and other modifications to improve the program's implementation. At this time EPA is not finalizing proposed provisions related to the generation of RINs from qualifying renewable electricity.

The Environmental Protection Agency (EPA) is approving, under the Clean Air Act (CAA), a State Implementation Plan (SIP) revision submitted by the Ohio Environmental Protection Agency (Ohio EPA) on September 7, 2022. Ohio EPA requests that EPA approve revised volatile organic compounds (VOCs) control rules under Chapter 3745-112 of the Ohio Administrative Code (OAC) into Ohio's SIP. The revised rules will reduce emissions that contribute to ozone formation and assist with efforts to achieve and maintain the 2015 ozone National Ambient Air Quality Standard (NAAQS). EPA finds that these rules are approvable because they are SIP strengthening measures. EPA proposed to approve this action on February 27, 2023, and received no adverse comments.

The Environmental Protection Agency (EPA) is proposing to approve, under the Clean Air Act (CAA), the limited maintenance plans (LMP) submitted on September 8, 2021, by the Ohio Environmental Protection Agency (OEPA) for the Canton-Massillon (Stark County), Cleveland-Akron-Lorain (Cuyahoga, Lake, Lorain, Medina, Portage, and Summit Counties) and Steubenville-Weirton (Ohio-West Virginia, Jefferson County) maintenance areas. The plans address the second 10- year maintenance periods for particulate matter with an aerodynamic diameter less than or equal to a nominal 2.5 micrometers (PM<INF>2.5</INF>). EPA is proposing to approve Ohio's LMP submissions for Canton-Massillon, Cleveland-Akron-Lorain, and Steubenville-Weirton because they provide for the maintenance of the 2006 24-hour PM<INF>2.5</INF> national ambient air quality standard (NAAQS) through the end of the second 10-year portion of the maintenance periods. In addition, EPA is initiating the process to find the Canton-Massillon, Cleveland-Akron-Lorain, and Steubenville-Weirton PM<INF>2.5</INF> LMPs adequate for transportation conformity purposes.

The Environmental Protection Agency (EPA) is taking final action to partially approve and partially disapprove revisions to the State Implementation Plan (SIP) submitted by the State of Missouri on February 17, 2022. In its submission, the Missouri Department of Natural Resources (MoDNR) requested that revisions to a 2016 Administrative Order on Consent (AOC) for controlling sulfur dioxide (SO<INF>2</INF>) emissions at the Lake Road power plant (hereinafter referred to as ``2016 AOC'') be approved in the SIP. This final action amends the SIP to establish more stringent fuel oil sulfur content limits, remove SO<INF>2</INF> emission limits that are no longer needed due to the strengthened fuel oil sulfur requirements, and streamline reporting requirements. The approved SIP changes meet the requirements of the Clean Air Act (CAA). This final action also disapproves a new provision in the AOC that would potentially allow Lake Road to exceed the fuel oil sulfur content limits on a temporary basis.

The Environmental Protection Agency (EPA) has submitted an information collection request (ICR), NSPS for VOC Emissions from Petroleum Refinery Wastewater Systems (EPA ICR Number 1136.14, OMB Control Number 2060-0172) to the Office of Management and Budget (OMB) for review and approval in accordance with the Paperwork Reduction Act. This is a proposed extension of the ICR, which is currently approved through August 31, 2023. Public comments were previously requested via the Federal Register on July 22, 2022 during a 60-day comment period. This notice allows for an additional 30 days for public comments.

The Environmental Protection Agency (EPA) is taking final action to partially approve and partially disapprove a revision to the Yolo-Solano Air Quality Management District (YSAQMD) portion of the California State Implementation Plan (SIP). The revision concerns the YSAQMD's demonstration regarding reasonably available control technology (RACT) requirements for the 2008 8-hour ozone National Ambient Air Quality Standards (NAAQS or ``standards'') in the portion of the Sacramento Metropolitan nonattainment area under the jurisdiction of the YSAQMD.

The Environmental Protection Agency (EPA) is taking final action to approve a revision to the State Implementation Plan (SIP) for the State of Missouri. This final action will amend the SIP to approve a revision submitted by the State of Missouri on September 20, 2022, to the existing state rule, ``Confidential Information.'' These revisions include structural, formatting and other text changes that are administrative in nature and do not impact the stringency of the SIP or air quality. The EPA's approval of this rule revision is in accordance with the requirements of the Clean Air Act (CAA).

The Environmental Protection Agency (EPA) is proposing to amend the National Emission Standards for Hazardous Air Pollutants (NESHAP) for Reciprocating Internal Combustion Engines (RICE), the New Source Performance Standards (NSPS) for Stationary Compression Ignition (CI) Internal Combustion Engines, and the NSPS for Stationary Spark Ignition (SI) Internal Combustion Engines, to add electronic reporting provisions. The addition of electronic reporting provisions will provide for simplified reporting by sources and enhance availability of data on sources to the EPA and the public. In addition, a small number of clarifications and corrections to these rules are being proposed to correct inadvertent and other minor errors in the Code of Federal Regulations (CFR), particularly related to tables. Finally, information is being solicited on the provisions specifying that emergency engines can operate for up to 50 hours per year to mitigate local transmission and/ or distribution limitations to avert potential voltage collapse or line overloads that could lead to the interruption of power supply in a local area or region.
