EPA Extends Deadline for Oil Spill Cleanup Product Listings
Published Date: 11/17/2025
Rule
Summary
The EPA is giving extra time for certain oil spill cleanup products to stay on the approved list, extending the deadline from December 12, 2025, to June 10, 2026. This helps companies using these products keep them available while new testing rules are still being worked out. The change kicks in right away, and the EPA wants your thoughts by December 17, 2025.
Analyzed Economic Effects
6 provisions identified: 2 benefits, 2 costs, 2 mixed.
Estimated Annual Cost Savings
EPA estimates the overall cost savings from this interim final rule to be between $1,017 and $5,063 per year. The Agency describes the action as providing burden reduction by extending the transition period for certain agent categories.
180-Day Extension for Three Agent Categories
EPA is extending the transition date for Surface Washing Agents, Herding Agents, and Solidifiers from December 12, 2025 to June 10, 2026, but only if no products in those categories are listed on the new NCP Product Schedule as of December 12, 2025. This means products in those categories that were conditionally listed on December 11, 2023 will remain available for use through June 10, 2026 while manufacturers may submit new listing packages.
No Extension for Dispersants, Bioremediation, Sorbents
The transition date for Dispersant and Bioremediation agent products and for Sorbent products remains December 12, 2025; those products must be submitted and listed under the amended criteria by that date. Products previously identified as sorbents will remain available for use only until December 12, 2025, after which they must be listed on the new Sorbent Product List to remain available.
MOSCA Category Not Extended or Transitioned
The rule does not extend the transition deadline for products previously listed under the Miscellaneous Oil Spill Control Agent (MOSCA) category; MOSCA products will not be transitioned to the new NCP Product Schedule and will no longer be listed after the December 12, 2023 transition deadline unless they are tested and qualify under a product category in the 2023 rule. EPA states removal of the MOSCA category does not automatically reassign those products to other agent categories.
Immediate Rule Effective Date and Comment Window
The interim final rule is effective immediately on November 17, 2025, and EPA is requesting comments to be received on or before December 17, 2025. EPA will respond to comments and may update this interim final action as appropriate.
Sectors Identified as Potentially Affected
EPA lists NAICS sectors potentially affected by this action, including (but not limited to) Chemical Manufacturing (325), Waste Management and Remediation Services (562), Merchant Wholesalers (423/424), Plastics and Rubber Products Manufacturing (326), Paper Manufacturing (322), Warehousing (493), and Professional, Scientific, and Technical Services (541). EPA says the table is not exhaustive but provides a guide for entities that could be regulated by this action.

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!
2026-19071, 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.
2026-18317, 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.
2026-14112, Amendments and Nonconformance Penalties for Model Year 2027 and Later Heavy-Duty Highway Engines and Amendments to Inducement Provisions for SCR-Equipped Diesel Engines
Starting with model year 2027, the EPA is updating rules for big truck engines to make sure they last longer and pollute less. They’re also letting engine makers pay penalties if their engines don’t meet standards, and tightening rules for special pollution-control systems on diesel engines. These changes affect truck and engine makers and kick in soon, with public feedback due by August 29, 2026.
2026-13667, Minor New Source Review Program Air Permitting Public Participation Requirements for State Implementation Plans
The EPA wants to give states more freedom to decide how much public input is needed when approving small air pollution sources or changes. This means local air agencies can tailor public participation to fit their community’s needs while still protecting air quality. If you’re involved in air permits, watch for comment deadlines and possible virtual hearings this summer!
2026-13263, Revisions To Establish the Sixth Unregulated Contaminant Monitoring Rule (UCMR 6) for Public Water Systems
The EPA is rolling out the sixth Unregulated Contaminant Monitoring Rule (UCMR 6) to check for new, sneaky chemicals in public drinking water. Big water systems serving 3,300+ people and some smaller ones will test for 30 different contaminants, including certain PFAS and pesticides, to keep our water safe. Comments and feedback are open until late August 2026, and the EPA will host fun online meetings to chat about the plan!
