# 2024-30964: Significant New Use Rules on Certain Chemical Substances (19-5.F) 2024-30964, Significant New Use Rules on Certain Chemical Substances (19-5.F), is a Federal Register rule from an unnamed agency published 2025-01-06, effective 2025-03-07 (as of 2026-06-11). - Canonical: https://policyrisk.com/federal-register/2024-30964 - As of: 2026-06-11 - Plain-text twin of the page above; the HTML and this file carry the same facts. ## Facts - Document number: 2024-30964 - Title: Significant New Use Rules on Certain Chemical Substances (19-5.F) - Type: Rule - Agencies: unknown - Citation: unknown - Published: 2025-01-06 - Effective: 2025-03-07 - Comments close: not stated - Significant: no - Touches household money: no - Regulation identifier numbers: none - Last updated: 2026-06-11 ## Summary The EPA is rolling out new rules that make companies tell them 90 days before starting new uses of certain chemicals. This gives the EPA time to check if the new use is safe before it happens. These rules kick in on March 7, 2025, and could affect anyone making or importing these chemicals, so plan ahead to avoid surprises or delays! ## Abstract 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). The SNURs require persons to notify EPA at least 90 days before commencing 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 use, under the conditions of use for that chemical substance, within the applicable review period. Persons may not commence manufacture or processing for the significant new use until they have submitted a Significant New Use Notice (SNUN), and EPA has conducted a review of the notice, made an appropriate determination on the notice, and has taken any risk management actions as are required as a result of that determination. ## Effects PRIA read - 90-Day Notice Before New Uses: cost, high. If you plan to start manufacturing (including importing) or processing any of the listed chemicals for a use the rule calls a “significant new use,” you must notify EPA at least 90 days before starting. You may not begin that activity until EPA reviews your Significant New Use Notice (SNUN), makes… - Estimated SNUN Submission Costs: cost, high. If you submit a SNUN, EPA estimates the total cost per submission at about $45,000 for large businesses and about $14,500 for qualifying small businesses. The estimate includes registration costs and a user fee of $37,000 (standard) or a reduced user fee of $6,480 for qualifying small businesses (F… - Export Notification Cost Per Country: cost, low. If you export a substance covered by these SNURs, you must give a one-time export notice to EPA for the first export or intended export to each country. EPA estimates the per-notification cost is about $106 (one-time per country). - SNUN Paperwork Time Burden: cost, medium. EPA estimates the annual paperwork burden for submitting a SNUN averages between 30 and 170 hours per submission. This includes time to review instructions, gather data, and complete the SNUN form. - Workplace Controls and High-Protection Respirators: cost, medium. For the chemical identified by PMN P-17-299, EPA designates workplace protection measures as a significant new use and requires that engineering or administrative controls be considered and implemented where feasible. When respirators are used, they must provide a NIOSH assigned protection factor (… - P-17-299 Use and Concentration Limits: cost, medium. For PMN P-17-299, it is a significant new use to use the substance other than as a thickener in paint or to use it in concentrations greater than 1% in formulated products; such uses trigger the SNUN requirement and EPA review. - P-18-172 Consumer Product and Use Limits: cost, medium. For PMN P-18-172 (calcium carbonate complexes), EPA designates as a significant new use: using the substance in consumer products except for architectural coatings, and using it other than as an auxiliary drier for architectural paints, industrial coatings, and stains. Those uses require submission… - Inhalation Exposure Triggers SNUN (P-19-118): cost, medium. For PMN P-19-118 (a substituted polyalkylenepoly generic), it is a significant new use to manufacture, process, or use the substance in any manner that results in inhalation exposure. Such activities require a SNUN before commencing. - Release-to-Water Designation (P-16-541): cost, low. For PMN P-16-541 (soybean meal reaction product), EPA designates release to water as a significant new use and applies the requirements specified in 40 CFR 721.90(a)(4), (b)(4), and (c)(4) with N=22. Those activities require a SNUN before starting. - Release-to-Water Designation (P-19-120): cost, low. For PMN P-19-120 (a generic alkenoic acid polymer alkali metal salt), EPA designates release to water as a significant new use and applies the requirements in 40 CFR 721.90(a)(4), (b)(4), and (c)(4) with N=78. Such releases require a SNUN before commencing. - Recordkeeping Requirements for Manufacturers: cost, low. Manufacturers and processors of the listed substances must comply with recordkeeping requirements specified in 40 CFR 721.125(a) through (c) and additional subsections referenced for each chemical (for example, (i) or (k)). These records must be maintained as part of compliance if you manufacture o… - Compliance Start Date and Judicial Promulgation: cost, low. The rule is effective March 7, 2025, and for purposes of judicial review it was promulgated at 1 p.m. (EST) on January 21, 2025. Businesses should plan for the March 7, 2025 effective date when scheduling activities that could be designated significant new uses. ## Related documents - [2026-20736](https://policyrisk.com/federal-register/2026-20736): Air Plan Approval; Michigan; Clean Data Determination for the Berrien, MI and Muskegon, MI Areas for the 2015 Ozone Standards, 2026-10-09 - [2026-20757](https://policyrisk.com/federal-register/2026-20757): Schedules of Controlled Substances; Removal of Exemption Status for Inactive Butalbital Products, 2026-10-09 - [2026-20727](https://policyrisk.com/federal-register/2026-20727): Medical Devices; Immunology and Microbiology Devices; Classification of the System for Detection of Nucleic Acid From Non-Viral Microorgani…, 2026-10-09 - [2026-20792](https://policyrisk.com/federal-register/2026-20792): Raisins Produced From Grapes Grown in California; Order Amending Marketing Order No. 989, 2026-10-09 - [C1-2026-20019](https://policyrisk.com/federal-register/C1-2026-20019): Fisheries of the Exclusive Economic Zone Off Alaska; Groundfish Reserves in the Bering Sea and Aleutian Islands Management Area, 2026-10-09 - [2026-20748](https://policyrisk.com/federal-register/2026-20748): Schedules of Controlled Substances: Placement of O-Desmethyltramadol in Schedule I; Correction, 2026-10-09 ## Sources - [2024-30964 on federalregister.gov](https://www.federalregister.gov/documents/2025/01/06/2024-30964/significant-new-use-rules-on-certain-chemical-substances-19-5f) - [2024-30964 as published (PDF)](https://www.govinfo.gov/content/pkg/FR-2025-01-06/pdf/2024-30964.pdf) ## Related - [Previous: 2024-29824, HOME Investment Partnerships Program: Program Updates and Streamlining](https://policyrisk.com/federal-register/2024-29824) - [Next: 2024-31140, Formulas for Calculating Hourly and Unit Fees for FGIS Services](https://policyrisk.com/federal-register/2024-31140) - [All Federal Register documents](https://policyrisk.com/federal-register) Source: PRIA, https://policyrisk.com/federal-register/2024-30964 (as of 2026-06-11).
