Environmental Protection Agency May 9, 2023 – Federal Register Recent Federal Regulation Documents

The Environmental Protection Agency (EPA) is finalizing amendments to the new source performance standards for Automobile and Light Duty Truck Surface Coating Operations pursuant to the review required by the Clean Air Act. The EPA determined that revisions to the NSPS were needed to reflect the degree of emission limitation achievable through the application of the best system of emission reduction (BSER). The EPA is therefore finalizing, as proposed, in a new NSPS subpart MMa, revised volatile organic compound (VOC) emission limits for prime coat, guide coat, and topcoat operations for affected facilities that commence construction, modification, or reconstruction after May 18, 2022. In addition, in the new NSPS subpart, the EPA is finalizing the proposed amendments: the addition of work practices to minimize VOC emissions; revision of the plastic parts provision; updates to the capture and control devices and the associated testing and monitoring requirements; revision of the transfer efficiency provisions; new test methods and alternative test methods; revision of the recordkeeping and reporting requirements, including the addition of electronic reporting; removing exemptions for periods of startup, shutdown, and malfunction; and other amendments to harmonize the new NSPS subpart and Automobile and Light Duty Truck Surface Coating National Emission Standards for Hazardous Air Pollutants (NESHAP) requirements. The EPA is also finalizing the proposed electronic reporting requirements in the NSPS subpart MM, applicable to sources that commence construction, reconstruction, or modification after October 5, 1979, and on or before May 18, 2022.

In this final action the Environmental Protection Agency (EPA) is addressing all or part of several State Implementation Plan (SIP) revisions submitted by the State of Colorado (as explained further in this document, we are taking no action on some specific portions of the State's submittals). We are approving specified parts of SIP revisions submitted by Colorado on March 22, 2021, related to Clean Air Act (CAA) requirements for the 2008 8-hour ozone National Ambient Air Quality Standards (NAAQS) for the Denver Metro/North Front Range (DMNFR) Serious nonattainment area. We are also finalizing a limited approval and limited disapproval of reasonably available control technology (RACT) SIP revisions from submissions made on May 14, 2018, May 8, 2019, May 13, 2020, March 22, 2021, May 18, 2021, and May 20, 2022. Further, we are finalizing a limited conditional approval and limited disapproval of additional RACT related SIP submissions made on May 31, 2017, and May 10, 2019. Finally, in this document, the EPA is notifying the public of findings as to certain motor vehicle emissions budgets in the DMNFR nonattainment area. This action is being taken under the authority of the CAA.

The Environmental Protection Agency (EPA) is taking direct final action on the authorization of South Carolina's changes to its hazardous waste program under the Resource Conservation and Recovery Act (RCRA), as amended. These changes were outlined in a September 26, 2022, application to the EPA. We have determined that these changes satisfy all requirements needed for final authorization.

The Environmental Protection Agency (EPA) is taking final action to approve a state implementation plan (SIP) revision submitted by the State of California addressing the nonattainment new source review (NNSR) requirements for the 2015 8-hour ozone National Ambient Air Quality Standards (NAAQS). This SIP revision addresses the Bay Area Air Quality Management District (BAAQMD or ``District'') portion of the California SIP. This action is being taken pursuant to the Clean Air Act (CAA or ``Act'') and its implementing regulations.
