Environmental Protection Agency – Federal Register Recent Federal Regulation Documents

This notice announces EPA's order for the cancellations and/or amendments to terminate uses, voluntarily requested by the registrants and accepted by the Agency, pursuant to the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA). This cancellation order follows a December 17, 2024, Federal Register Notice of Receipt of Requests from the registrants listed in Table 3 of Unit II to voluntarily cancel and/or amend to terminate uses of all these product registrations. In the December 17, 2024, notice, EPA indicated that it would issue an order implementing the cancellations and/or amendments to terminate uses, unless the Agency received substantive comments within the 30-day comment period that would merit its further review of these requests, or unless the registrants withdrew their requests. The Agency received one anonymous comment on the notice, but it did not merit its further review of the requests. Further, the registrants did not withdraw their requests. Accordingly, EPA hereby issues in this notice a cancellation order granting the requested cancellations and/or amendments to terminate uses. Any distribution, sale, or use of the products subject to this cancellation order is permitted only in accordance with the terms of this order, including any existing stocks provisions.

EPA is announcing a specific exemption request from the New York State Department of Environmental Conservation to use the insecticide isocycloseram (CAS No. 2061933-85-3) to treat up to 2,500 acres of bulb onion to control onion thrips. The applicant proposes the use of a new chemical which has not been registered by EPA. Due to the urgent nature of the emergency, the limited time available to authorize this request in time for the use season, and the recently concluded public participation process for the related proposed Section 3 product registration for the same use, EPA has eliminated the public comment period. Nonetheless, interested parties may still contact the Agency with information about this notice and treatment program.

This action finalizes the periodic review by the U.S. Environmental Protection Agency (EPA) of the emissions standards and other requirements for Other Solid Waste Incineration (OSWI) units in the OSWI New Source Performance Standards (NSPS) and Emission Guidelines (EG).

This regulation establishes exemptions from the requirement of a tolerance for residues of Pepino mosaic virus, strain LP, isolate VX1 and Pepino mosaic virus, strain CH2, isolate VC1 in or on all food commodities when used in accordance with label directions and good agricultural practices. Valto BV submitted a petition to the EPA under the Federal Food, Drug, and Cosmetic Act (FFDCA), requesting these exemptions from the requirement of a tolerance. This regulation eliminates the need to establish a maximum permissible level for residues of Pepino mosaic virus, strain LP, isolate VX1 and Pepino mosaic virus, strain CH2, isolate VC1 under FFDCA when used in accordance with these exemptions.

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.

The Environmental Protection Agency (EPA) Administrator signed an order dated April 30, 2025, denying a petition dated December 6, 2024, from the Center for Biological Diversity.

Copper Ore Mining and Processing Operations ("Morenci Mine") in Greenlee County, Arizona.

The Environmental Protection Agency (EPA or Agency) is extending the postponement of the effective date of certain regulatory provisions of the final rule entitled "Trichloroethylene (TCE); Regulation Under the Toxic Substances Control Act (TSCA)" for an additional 60 days. Specifically, this postponement applies to the conditions imposed on the uses with TSCA exemptions.

The Toxic Substances Control Act (TSCA) requires EPA to publish in the Federal Register a statement of its findings after its review of certain TSCA submissions when EPA makes a finding that a new chemical substance or significant new use is not likely to present an unreasonable risk of injury to health or the environment. Such statements apply to premanufacture notices (PMNs), microbial commercial activity notices (MCANs), and significant new use notices (SNUNs) submitted to EPA under TSCA. This document presents statements of findings made by EPA on such submissions during the period from April 1, 2025 to April 30, 2025.

The Environmental Protection Agency (EPA) is proposing a clean data determination (CDD) for the Piti-Cabras, Guam sulfur dioxide (SO2) nonattainment area ("Piti-Cabras area") based on our determination that the area has attained the 2010 1-hour SO2 National Ambient Air Quality Standard (NAAQS, "standard," or "2010 SO2 NAAQS"). In designated nonattainment areas where air quality data demonstrate that a NAAQS has been attained, the EPA interprets certain requirements of the Clean Air Act (CAA) as no longer applicable for so long as air quality continues to meet the standard. Under this Clean Data Policy, the EPA may issue a determination of attainment, known as a CDD, that a nonattainment area is attaining the relevant NAAQS. If finalized, this proposed CDD would suspend the obligation to submit certain attainment planning requirements for the Piti-Cabras area for as long as the area continues to attain the 2010 SO2 NAAQS or until the area is formally redesignated.

The Environmental Protection Agency (EPA) has submitted an information collection request (ICR), NSPS for the Phosphate Fertilizer Industry (EPA ICR Number 1061.16, OMB Control Number 2060-0037) 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 June 30, 2025. Public comments were previously requested via the Federal Register on August 6, 2024 during a 60-day comment period. This notice allows for an additional 30 days for public comments.

The Environmental Protection Agency (EPA) is approving revisions to the New York State Implementation Plan (SIP) concerning the control and reduction of sulfur and particulate matter emissions from facilities in New York State. The SIP revisions consist of amendments to regulations outlined within New York's Codes, Rules and Regulations (NYCRR) for sulfur in fuel limits and the use of waste oil as fuel. The intended effect of the revisions is to approve control strategies, required by the Clean Air Act (CAA), which will result in emission reductions that will help attain and maintain National Ambient Air Quality Standards (NAAQS) for sulfur dioxide and fine particulate matter emissions throughout New York State. Additionally, the revisions will establish applicability criteria, composition limits, and permitting requirements for waste oils; provide monitoring, recordkeeping, and reporting requirements for facilities that are determined eligible to burn waste oil; update conditions required for the firing of waste oils in space heaters at automotive maintenance/service facilities to align with both Federal and New York State hazardous waste regulations; and simplify and streamline implementation of the regulation through the correction of typographical errors and elimination of obsolete regulatory references within provisions. This action is being taken in accordance with the requirements of the CAA.

The Environmental Protection Agency (EPA) has submitted an information collection request (ICR), NESHAP for Chromium Emissions from Hard and Decorative Chromium Electroplating and Chromium Anodizing Tanks (EPA ICR Number 1611.14, OMB Control Number 2060-0327) 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 June 30, 2025. Public comments were previously requested via the Federal Register on August 6, 2024 during a 60-day comment period. This notice allows for an additional 30 days for public comments.

The Environmental Protection Agency (EPA) is making an interim final determination that the California Air Resources Board (CARB) has submitted a rule on behalf of the Eastern Kern Air Pollution Control District (EKAPCD or "District") that addresses deficiencies in its Clean Air Act (CAA or "Act") State Implementation Plan (SIP) concerning emissions of oxides of nitrogen (NOX) from stationary gas turbines. This determination is based on a proposed approval, published elsewhere in this issue of the Federal Register, of EKAPCD Rule 425 that regulates this category of sources. The effect of this interim final determination is that the application of offset sanctions that was triggered by a previous limited disapproval by the EPA in 2023 is now stayed, and the application of highway sanctions is now deferred. If the EPA finalizes its approval of EKAPCD's submission, relief from these sanctions will become permanent.

The Environmental Protection Agency (EPA) Acting Administrator signed an order dated January 7, 2025, granting in part and denying in part a petition dated July 10, 2024, from Del Amo Action Committee. The petition requested that the EPA object to a Clean Air Act (CAA) title V operating permit renewal issued by the South Coast Air Quality Management District (SCAQMD) to Torrance Refining Company, LLC, located in Los Angeles County, California.

The Environmental Protection Agency (EPA) has submitted an information collection request (ICR), NESHAP for Flexible Polyurethane Foam Product (EPA ICR Number 1783.12, OMB Control Number 2060-0357) 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 June 30, 2025. Public comments were previously requested via the Federal Register on August 6, 2024 during a 60-day comment period. This notice allows for an additional 30 days for public comments.

The Oklahoma Department of Environmental Quality (ODEQ) has submitted updated regulations for receiving delegation and approval of its program for the implementation and enforcement of certain National Emission Standards for Hazardous Air Pollutants (NESHAP) for all sources, as provided for under previously approved delegation mechanisms. The updated State regulations incorporate by reference certain NESHAP promulgated by the Environmental Protection Agency (EPA), as they existed through June 30, 2022. The EPA is providing notice that it is taking final action to approve the delegation of certain NESHAP to ODEQ. The final delegation of authority under this action applies to sources located in certain areas of Indian country as discussed herein.

The Environmental Protection Agency (EPA) is proposing to find that the Huntington County, Indiana nonattainment area failed to attain the 2010 Sulfur Dioxide (SO2) National Ambient Air Quality Standard (NAAQS) by the applicable attainment date of April 9, 2023. EPA is also proposing to approve revisions into the Indiana State Implementation Plan (SIP) intended to provide for attainment of the 2010 SO2 NAAQS for the Huntington County nonattainment area. These SIP submissions include Indiana's attainment demonstration and other planning elements required under the Clean Air Act (CAA), and a Commissioner's Order containing enforceable emission limits. Further, EPA is proposing to find that the provisions of Indiana's SIP submittal adequately provide for attainment of the NAAQS and that the plan meets all other applicable CAA requirements.

The Environmental Protection Agency (EPA) is proposing approval of a revision to the Guam State Implementation Plan (SIP). This revision governs the Guam Environmental Protection Agency's (GEPA's) issuance of permits for stationary sources and focuses on the preconstruction review and permitting of major sources and major modifications under part D of title I of the Clean Air Act (CAA or "the Act"). We are taking comments on this proposal and plan to follow with a final action.
