Significant New Use Rules on Certain Chemical Substances (22-4.5e)
EPA is issuing 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. The SNURs require persons to notify EPA at least 90 days before commencing the manufacture (defined by statute to include import) or processing of any of these chemical substances for an activity that is designated as a significant new use in the SNUR. 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.

Air Plan Approval; WA; Southwest Clean Air Agency; Revisions to Excess Emissions, Startup, Shutdown, and General Requirements
The Environmental Protection Agency (EPA) is proposing to approve Washington State Implementation Plan (SIP) revisions to the Southwest Clean Air Agency (SWCAA) air quality regulations submitted by the State of Washington, through the Department of Ecology (Ecology) on June 22, 2023. The revisions were submitted in part to respond to the EPA's June 12, 2015 "SIP call" in which the EPA found a provision in the Washington SIP applicable in the area regulated by SWCAA to be substantially inadequate, providing affirmative defenses that operate to limit the jurisdiction of the Federal court in an enforcement action related to excess emissions during startup, shutdown, and malfunction (SSM) events. The EPA is proposing approval of the SIP revisions and proposing to determine that the submitted revisions to the substantially inadequate provision corrects the deficiency identified in the 2015 SSM SIP call and the EPA's January 2022 finding of failure to submit. Washington withdrew some portions of the revisions submitted that were not identified in the 2015 SSM SIP call and therefore the EPA is not proposing action on those withdrawn portions.
Federal “Good Neighbor Plan” for the 2015 Ozone National Ambient Air Quality Standards; Notice on Remand of the Record of the Good Neighbor Plan To Respond to Certain Comments
The Environmental Protection Agency (EPA) is addressing certain comments that were submitted on the proposed Good Neighbor Plan that the Supreme Court of the United States concluded the EPA had likely not sufficiently addressed in the final Good Neighbor Plan. The EPA is providing a fuller explanation of its reasoning at the time of its action in response to these comments. The Good Neighbor Plan addressed 23 states' obligations to eliminate significant contribution to nonattainment or interference with maintenance of the 2015 ozone national ambient air quality standards (NAAQS), pursuant to the "good neighbor" provision of the Clean Air Act (CAA or Act). On September 12, 2024, the D.C. Circuit Court of Appeals remanded the record of the Good Neighbor Plan to the EPA to permit the Agency to further respond to comments related to the Good Neighbor Plan's operation if one or more upwind States were no longer participating. In this document, the EPA responds to the comments by more fully explaining why the Good Neighbor Plan appropriately defines each state's obligations, regardless of the status of the rule in other states, and can be implemented without modification in any individual state or combination of states covered by the rule.

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. The SNURs 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.
