EPA Opens Comment Window on Companies’ Pesticide Exit Plans
Published Date: 11/12/2026
Notice
Summary
The EPA got requests from companies to cancel some pesticide products or stop certain uses of them. If no big objections come in by December 14, 2026, these changes will go through, affecting farmers, sellers, and users of these pesticides. This means some products might disappear from shelves soon, so folks should pay attention and act fast if they want to comment.
Analyzed Economic Effects
6 provisions identified: 0 benefits, 5 costs, 1 mixed.
Three Pesticide Registrations May Be Canceled
EPA received voluntary cancellation requests for the registrations 524-623 (Tioxazafen Technical), 524-624 (Mon 102133 SC Tioxazafen Nematicide Seed Treatment), and 7946-30 (Abacide 2HP, abamectin). EPA intends to grant these requests at the close of the public comment period unless substantive comments are received or the registrants withdraw; comments must be received by December 14, 2026. If cancelled, sale, distribution, or use of these products will be restricted as described in the final cancellation order.
Formaldehyde Solution Use for Product Preservation Removed
EPA received a request to amend registration 8743-17 (Formaldehyde Solution 37%) to terminate its in-container preservation uses for a wide range of industrial and household consumer products and for railway cars. EPA intends to grant the request unless substantive comments are received or the registrant withdraws; comments are due by December 14, 2026. If finalized, manufacturers using this ingredient for the listed in-container preservation purposes would no longer be able to rely on that registered use.
Physan 20 Outdoor Plant Uses Terminated
EPA received a request to amend registration 55364-5 (Physan 20) to terminate uses including disinfection of plant cuttings, seeds and seedlings propagated outdoors, trees, lawn and turfgrass, and certain outdoor plant pathogen control applications (not greenhouse). EPA intends to grant the request unless substantive comments are filed or the registrant withdraws; comments must be received by December 14, 2026. If finalized, nurseries, landscapers, and growers who rely on these outdoor uses would lose the registered ability to use Physan 20 for those purposes.
MCPA Acid Use for Alfalfa Forage Removed
EPA received a request to amend registration 81598-76 (Technical MCPA Acid) to terminate its use on alfalfa hay and forage. EPA intends to grant the request unless substantive comments are filed or the registrant withdraws; comments must be received by December 14, 2026. If finalized, growers who use MCPA acid on alfalfa hay and forage would no longer be able to use this registered product for that crop.
Residential Use of SunPac Mildewcide Ending
EPA received a request to amend registration 4972-43 (SunPac Mildewcide, paraformaldehyde 91%) to terminate the product's residential use. EPA intends to grant the request unless substantive comments are filed or the registrant withdraws the request; comments must be received by December 14, 2026. If the amendment is finalized, residential users will no longer be able to buy or use this product for residential mildew control once the cancellation/amendment restrictions take effect.
Time Limits on Selling Existing Stocks
If EPA grants the cancellations in Table 1, registrants may sell and distribute existing stocks of those voluntarily canceled products for 1 year after the effective date of the cancellation order. For products amended to terminate uses (Table 2), once EPA has approved amended labels, registrants may sell or distribute under the previously approved labeling for 18 months after the cancellation order is published. Other sellers and users may generally sell, distribute, or use existing stocks until supplies are exhausted if actions are consistent with the previously approved labeling. These time limits will begin on the publication date of the cancellation order.

2026-22082, Additional Reconsideration Standards of Performance for New, Reconstructed, and Modified Sources and Emissions Guidelines for Existing Sources: Oil and Natural Gas Sector Climate Review
The EPA is updating rules for oil and natural gas companies to fix issues from last year’s changes. They’re scrapping the Super Emitter Program, splitting well sites into clearer groups, and tweaking rules on leaks, equipment, and inspections. Companies should get ready to comment by December 16, 2026, as these updates could affect how they manage emissions and operate equipment.
2026-21155, Renewable Fuel Standard (RFS) Program: Reallocation of Additional 2025 Small Refinery Exemptions
The EPA is updating how it handles small refinery exemptions (SREs) for 2025 under the Renewable Fuel Standard. They’re deciding whether to spread the extra exemptions between 2026 and 2027 or give them all to 2027. This change might also push back the 2026 compliance deadline, affecting refiners and renewable fuel producers with potential timing and cost impacts.
2026-20849, Clean Water Act Hazardous Substance Facility Response Plans: Compliance Date Delay and Changes To Reflect Administration Policy
The EPA is giving facilities more time to meet new Clean Water Act rules for handling hazardous spills, pushing back the deadline to help them get ready. They’re also removing mentions of climate change and environmental justice to match new government policies. This delay helps facilities plan better without rushing and lets the EPA rethink the rules if needed.
2026-19071, Partial Repeal of the Carbon Pollution Standards for Fossil Fuel-Fired Electric Generating Units
The EPA is rolling back most of the 2024 rules that limited carbon pollution from fossil fuel power plants. This change affects coal and gas plants by easing some strict limits on emissions and carbon capture technology. The new rules kick in on November 16, 2026, potentially saving money for power plants but raising questions about pollution control.
2026-19072, Rescission of the Greenhouse Gas Findings for Fossil Fuel-Fired Power Plants and Repeal of Regulations for Power Plant Greenhouse Gas Emissions Under Clean Air Act Section 111
The EPA is proposing to cancel all greenhouse gas rules for fossil fuel power plants, saying the law doesn’t let them regulate these emissions for climate reasons. This change affects power plants across the U.S. and could impact future pollution limits and costs. Comments on this proposal are open until November 2, 2026, so now’s the time to speak up!
2026-18317, Updated Definition of “Waters of the United States”
The purpose of this supplemental notice of proposed rulemaking is for the U.S. Environmental Protection Agency (EPA) and the Department of the Army ("the agencies") to supplement and seek additional comment on certain aspects of an earlier proposal, published on November 20, 2025, to revise the regulations defining the scope of waters federally covered under the Clean Water Act in light of the U.S. Supreme Court's 2023 decision in Sackett v. Environmental Protection Agency. As stated in the agencies' November 20, 2025 Notice of Proposed Rulemaking (NPRM), the agencies intend for this rulemaking to provide greater regulatory certainty and increase Clean Water Act program predictability and consistency by clarifying the definition of "waters of the United States." After consideration of the public comments received on the NPRM, the agencies are issuing this notice to supplement the NPRM with additional regulatory options on certain aspects of the proposed rule.
