This determination of clean data is based upon complete, quality- assured, and certified ambient air monitoring data for the 2023-2025 design value period showing that the Missouri portion of the area achieved attainment of the 2015 ozone NAAQS. The 2023-2025 design value relies upon EPA concurrence on a portion of the exceptional events request as submitted by the Missouri Department of Natural Resources (MoDNR) on November 3, 2025, and concurred on by the EPA on January 27, 2026. The EPA is also approving Missouri's November 3, 2025, clean data determination request. This final clean data determination suspends the obligations of the State of Missouri to submit certain nonattainment area planning requirements for as long as the Missouri portion of the St. Louis area continues to attain the 2015 ozone NAAQS. In a separate action, the EPA is finalizing a similar determination for the Illinois portion of the St. Louis area.

Determination To Defer Sanctions; Arizona; Maricopa County Air Quality Department; Gasoline Loading

The U.S. Environmental Protection Agency (EPA) is making an interim final determination that the Arizona Department of Environmental Quality (ADEQ) has submitted rules on behalf of the Maricopa County Air Quality Department (MCAQD or "County") that addresses deficiencies in its Clean Air Act (CAA or "Act") State Implementation Plan (SIP) concerning emissions of volatile organic compounds (VOC) from loading of organic liquids and gasoline. This determination is based on a proposed approval of MCAQD Rule 352 and conditional approval of MCAQD Rule 353, published elsewhere in this issue of the Federal Register, that regulate this category of sources. The effect of this interim final determination is that the application of offset and highway sanctions that was triggered by a previous limited disapproval by the EPA in 2025 is now deferred. If the EPA finalizes its approval and conditional approval of MCAQD's submission, relief from these sanctions will become permanent.

The U.S. Environmental Protection Agency (EPA) is proposing to conditionally approve a State Implementation Plan (SIP) revision submitted by the State of New Hampshire on December 24, 2025, through the New Hampshire Department of Environmental Services (NHDES). The proposed revision would remove the Statewide motor vehicle inspection and maintenance (I/M) program as an active measure, which was previously approved into the SIP to address emissions from on-road sources. In accordance with plan revision requirements of the Clean Air Act (CAA), the SIP submittal contains a demonstration that the removal of the I/M program will not interfere with New Hampshire's compliance with any National Ambient Air Quality Standard (NAAQS) or with any applicable requirement of the CAA. In a letter to the EPA, NHDES committed to submitting an additional SIP revision within one year of a final conditional approval to address maintenance plan requirements.

Public Water System Supervision Program Revision Approvals for the States of Indiana and Illinois

Notice is hereby given that the Environmental Protection Agency (EPA) has approved the State of Indiana's revisions to its Public Water System Supervision (PWSS) Program under the federal Safe Drinking Water Act (SDWA) for revisions to four National Primary Drinking Water Regulations (NPDWRs): the Ground Water Rule (GWR), Lead and Copper Rule--Short Term Revisions (LCR-STR), Long-Term 2 Enhanced Surface Water Treatment Rule (LT2 ESWTR), and the Stage 2 Disinfectants and Disinfection Byproducts Rule (Stage 2 D/DBPR). The EPA has determined that the State of Indiana's PWSS program regulations and the revisions thereto are no less stringent than the above corresponding federal regulations and thus give the Indiana Department of Environmental Management primary enforcement responsibility for the GWR, LCR-STR, LT2 ESWTR, and Stage 2 D/DBPR. Notice is also hereby given that the EPA has approved the State of Illinois' revisions to its PWSS program under SDWA for adoption of the Filter Backwash Recycling Rule (FBRR). The EPA has determined that the State of Illinois' PWSS Program regulations and the revisions thereto are no less stringent than the NPDWR and thus give the Illinois Environmental Protection Agency primary enforcement responsibility for the FBRR. These determinations on the Indiana and Illinois requests for approval of such primacy enforcement responsibility shall take effect in accordance with procedures described below, subject to timely substantial requests for public hearing. This approval action does not extend to public water systems in Indian Country. By approving this revision, the EPA does not intend to affect the rights of federally recognized Indian Tribes in either Indiana or Illinois, nor does it intend to limit existing rights of either the State of Indiana or the State of Illinois.

Air Plan Approval; Connecticut; Plan for Inclusion of a Consent Order No. 8383-Algonquin Gas Transmission, LLC and Negative Declaration for Rubber Tire Manufacturing Sources

The Environmental Protection Agency (EPA) is approving a State Implementation Plan (SIP) revision submitted by the State of Connecticut to address certain Federal requirements for the 2008 and 2015 8-hour ozone National Ambient Air Quality Standards (NAAQS) under the Clean Air Act (CAA). This revision approves a source-specific SIP revision for Algonquin Gas Transmission, LLC's Cromwell compressor station facility in Cromwell, CT, to address reasonably available control technology (RACT) determinations for major stationary sources of volatile organic compounds (VOC). The CAA requires states to submit SIP revisions addressing RACT requirements for ozone nonattainment areas classified as Moderate or higher and for any portion of the state located in an ozone transport region (OTR). RACT determinations are required for this source because it is located in the New York-Northern New Jersey-Long Island, NY-NJ-CT 2008 ozone Severe nonattainment area and 2015 ozone Serious nonattainment area and because Connecticut is in the OTR. The EPA is also approving a negative declaration for existing rubber tire manufacturing sources statewide. This action is being taken in accordance with the Clean Air Act.

Significant New Use Rules on Certain Chemical Substances (26-3)

EPA is proposing significant new use rules (SNURs) under the Toxic Substances Control Act (TSCA) for certain chemical substances that were the subject of premanufacture notices (PMNs) and are also subject to an Order issued by EPA pursuant to TSCA. Once finalized, the SNURs would require persons who intend to manufacture (defined by statute to include import) or process any of these chemical substances for an activity that is proposed as a significant new use by this rulemaking to notify EPA at least 90 days before commencing that activity. The required notification initiates EPA's evaluation of the conditions of that use for that chemical substance. In addition, the manufacture or processing for the significant new use may not commence until EPA has conducted a review of the required notification, made an appropriate determination regarding that notification, and taken such actions as required by that determination.
