The Environmental Protection Agency (EPA) is making an interim final determination that the State of Alaska has submitted state implementation plan (SIP) revisions that satisfy outstanding Clean Air Act requirements. This interim final determination defers the imposition of sanctions for the 2006 24-hour fine particulate matter (PM<INF>2.5</INF>) Fairbanks North Star Borough PM<INF>2.5</INF> nonattainment area. This determination is based on a proposed approval, published in the "Proposed Rules" section of this Federal Register, of the SIP revisions, submitted by the State of Alaska (Alaska or the State) on December 4, 2024, to address Clean Air Act requirements for the 2006 24-hour PM<INF>2.5</INF> national ambient air quality standards (NAAQS).

This action finalizes the Clean Air Act (CAA) technology review (TR) conducted for the commercial and industrial dry cleaning facilities using perchloroethylene (PCE) as the cleaning solvent (PCE Dry Cleaning) source categories regulated under National Emission Standards for Hazardous air Pollutants (NESHAP). This final rule does not finalize the changes made at proposal and makes no amendments to the current NESHAP given the recently finalized action under the Toxic Substance Control Act (TSCA) which has instituted a 10-year phaseout of the use of PCE for dry cleaning.

Learn More⚖️New EPA Rules Affecting Chemical Substance Manufacturers
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). The SNURs require persons to notify EPA at least 90 days before commencing 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 use, under the conditions of use for that chemical substance, within the applicable review period. Persons may not commence manufacture or processing for the significant new use until they have submitted a Significant New Use Notice (SNUN), and EPA has conducted a review of the notice, made an appropriate determination on the notice, and has taken any risk management actions as are required as a result of that determination.
