EPA Proposes New Reporting Rules for Chemical Uses
Published Date: 6/10/2026
Proposed Rule
Summary
The EPA is proposing new rules that require companies to tell them 90 days before using certain chemicals in new ways. This gives the EPA time to check if the new use is safe before it starts. If you make or import these chemicals, you need to watch the July 10, 2026 deadline to share your plans and avoid delays or fines.
Analyzed Economic Effects
6 provisions identified: 0 benefits, 6 costs, 0 mixed.
High SNUN Submission Costs
If you submit a SNUN, EPA estimates the cost to prepare and submit one SNUN is about $45,496 for a large business and $14,976 for a small business. Submitting businesses must also pay a user fee of $37,000 (or a reduced fee of $6,480 for small businesses as defined at 13 CFR 121.201).
90‑Day Notice Before New Uses
If you plan to manufacture (including import) or process any chemical listed in this proposed rule for an activity the rule calls a “significant new use,” you must notify EPA at least 90 days before starting that activity. You may not begin the activity until EPA reviews your Significant New Use Notice (SNUN), makes a determination, and takes any required action.
June 10, 2026 Cutoff for Ongoing Uses
EPA designates June 10, 2026 as the cutoff date for whether a use is ongoing. Persons who begin manufacture or processing of a listed substance for a significant new use on or after June 10, 2026 would have to stop that activity when the final rule becomes effective and must comply with SNUR notification requirements to resume.
Mandatory Protective Measures and Limits
The proposed SNURs identify absence of the TSCA Order protective measures as a significant new use. Required protections across the listed substances include use of personal protective equipment, hazard communication and Safety Data Sheets, prohibitions on use in consumer products, inhalation exposure controls, respirator requirements (examples: NIOSH‑certified respirator with APF ≥1,000 or APF ≥50 for specific substances), production or concentration limits (examples: concentration limits of 5% or 3% by weight in formulations), particle size or percent‑by‑weight thresholds, and surface water release limits (examples: 669 ppb, 9 ppb, 0.7 ppb, 58 ppb, 3143 ppb, 89 ppb, 316 ppb for various substances).
Testing Expectations and Regulatory Risk
EPA may request or require testing data when reviewing a SNUN and encourages early consultation; submitting a SNUN without test data may increase the likelihood EPA will take action under TSCA sections 5(e) or 5(f). EPA also encourages use of alternative test methods (New Approach Methodologies) where available.
Export Notification and Per‑Country Cost
If you export a listed substance on or after July 10, 2026, you must provide a one‑time export notification to EPA for the first export or intended export to a particular country under TSCA section 12(b). EPA estimates the per‑notification cost is approximately $106.

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!
2026-12927, U.S. Ecology Nevada, Inc. High Mercury Subcategory Wastes Land Disposal Restrictions Variance
The EPA is giving U.S. Ecology Nevada a special green light to handle and dispose of high-mercury waste a bit differently than usual. This means mercury waste treated in Pennsylvania can now be safely sent to U.S. Ecology’s Nevada site for disposal under new rules starting July 27, 2026. This change helps protect people and the environment while keeping mercury waste management efficient and cost-effective.
2026-11047, National Emission Standards for Hazardous Air Pollutants From Hazardous Waste Combustors: Residual Risk and Technology Review
The EPA just updated rules for places that burn hazardous waste, like incinerators and boilers, to keep the air safe and clean. They confirmed current standards work well but added new limits on harmful gases like hydrogen fluoride and hydrogen cyanide. These changes start June 3, 2026, and include easier electronic reporting and some new rules for startup and shutdown times—helping protect health without big costs.
