EPA Tweaks Chemical Rules to Ease Some New Uses
Published Date: 11/10/2026
Rule
Summary
The EPA is updating rules about certain chemicals to make it easier to use some new ways without extra paperwork, based on fresh data and past reports. Companies making or using these chemicals need to know the new rules start January 11, 2027, so they can stay in the clear and avoid surprises. This update helps keep everyone safe while cutting down on unnecessary red tape.
Analyzed Economic Effects
7 provisions identified: 2 benefits, 5 costs, 0 mixed.
SNUN submission costs for firms
If you submit a Significant New Use Notice (SNUN), EPA estimates total preparation and submission costs of about $45,000 per SNUN for large business submitters and about $14,500 per SNUN for qualifying small business submitters. These estimates include the user fee and registration costs.
New SNUR effective and promulgation dates
The final rule becomes effective January 11, 2027, and for purposes of judicial review is promulgated at 1 p.m. (EST) on November 24, 2026. If you manufacture, process, or use the listed substances, these are the dates by which the new SNUR requirements take effect.
Reduced SNUN user fee for small businesses
Qualifying small businesses pay a reduced SNUN user fee of $6,480 instead of $37,000, which EPA says reduces the total SNUN submission cost to about $14,500 for small firms. EPA states this reduced fee is available under the fee rules (40 CFR 700.45(c)(1)(ii) and (d)).
Cutoff date for ongoing uses: Oct 28, 2025
EPA designates October 28, 2025 (the date of publication of the proposed rule) as the cutoff for determining whether a use is 'ongoing.' If a person began commercial manufacture or processing for a use after that publication date and before the final rule's effective date, they must cease the activity on the effective date and may only resume after complying with SNUR notification requirements.
Some reported new uses now allowed without extra notice
EPA states it is amending SNURs by allowing certain new uses reported in SNUNs or PMNs to proceed without additional notification requirements and by modifying notification requirements based on review of SNUN/PMN submissions and new test data. This change may reduce the number of new SNUNs some firms must file.
Export notification one-time cost
If you export a substance subject to a SNUR, you must submit a one-time export notification to EPA the first time you export to a particular country; EPA estimates the per-notification cost at approximately $106. The total cost depends on how many countries you export to.
Specific recordkeeping requirements for listed substances
For some amended SNURs EPA imposes specific recordkeeping obligations: e.g., for PMN P-03-622 recordkeeping per Sec. 721.125(a)-(i) and (k) applies, and for the microorganism Trichoderma reesei (Sec. 725.1080) recordkeeping per Sec. 725.950(b)(2)-(4) and documentation of compliance with paragraph (a)(2) are required. These records must be maintained by manufacturers and processors.

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.
