EPA Rethinks Carbon Tetrachloride Rules: Toxic Chemical Safety Up for Debate
Published Date: 10/9/2025
Notice
Summary
The EPA is asking for your thoughts on its rules about carbon tetrachloride (CTC), a chemical that can be harmful at work. They made new rules in late 2024 to keep people safe but now need to rethink some parts after legal challenges. If you’re involved in industries using CTC, this could affect how you work and what safety steps you must follow—so get your comments in by November 10, 2025!
Analyzed Economic Effects
2 provisions identified: 0 benefits, 2 costs, 0 mixed.
Workplace exposure limit set at 0.03 ppm
If you work with carbon tetrachloride (CTC) or run a workplace that does, the CTC final rule set an Existing Chemical Exposure Limit (ECEL) of 0.03 parts per million (ppm) as an 8-hour time-weighted average (TWA) under the Workplace Chemical Protection Program (see 40 CFR 751.703 and 751.707(b)). EPA is asking for comment on the feasibility of exposure monitoring and whether a different exposure limit would be more appropriate; submit comments by November 10, 2025.
Prohibitions on certain CTC uses may affect businesses
The December 18, 2024 CTC final rule required various workplace exposure controls and prohibited certain industrial and commercial uses of carbon tetrachloride; those prohibitions and requirements currently affect manufacturers, processors, distributors, users, and disposers of CTC. EPA announced on September 12, 2025 that it will reconsider the rule and is soliciting public comment to inform any amendments; comments are due November 10, 2025.

2026-10086 — Extending the Compliance Deadline for the PFOA and PFOS Maximum Contaminant Levels
The EPA is giving water systems more time to meet safety rules for two harmful chemicals, PFOA and PFOS, by extending the deadline from April 2029 to April 2031 if they ask for it. This helps water providers get ready without rushing, keeping our drinking water safe. The EPA wants your thoughts and will hold a public hearing in July 2026 to hear from everyone.
2026-10085 — Rescission of Regulatory Determinations and Removal of Related Provisions for Four PFAS Substances (PFHxS, PFNA, HFPO-DA (GenX), and the Mixture of These Three PFAS Plus PFBS)
The EPA is proposing to undo its rules for four PFAS chemicals (PFHxS, PFNA, GenX, and a mix including PFBS) in drinking water because the original process wasn’t done right. This means public water systems won’t have to monitor or treat these chemicals for now. People and water providers should weigh in by July 20, 2026, and a virtual hearing happens July 7.
2026-09895 — Effluent Limitations Guidelines and Standards for the Steam Electric Power Generating Point Source Category-Unmanaged Combustion Residual Leachate
The EPA is updating rules for steam electric power plants to better control dirty water leaking from leftover coal waste. This change affects existing power plants and is expected to save up to $1 billion a year while protecting water quality. Comments on the proposal are open until June 17, 2026, so now’s the time to speak up!
2026-09524 — Begin Actual Construction in the New Source Review (NSR) Preconstruction Permitting Program
The EPA is updating rules about when companies can start building big projects that might affect air quality. Now, they can begin building parts that don’t release pollution before getting a full air permit, making things clearer and easier. This change mainly affects businesses planning major construction and could speed up projects without extra costs, but comments are due by June 29, 2026.
2026-09179 — Definition of Hazardous Waste Applicable to Corrective Action for Releases From Solid Waste Management Units; Withdrawal
The EPA has decided to cancel its plan to change the rules about what counts as hazardous waste for cleaning up pollution at certain waste sites. This means businesses and cleanup crews won’t have to deal with the confusing new rules that were proposed. The withdrawal takes effect immediately, so no extra costs or changes will happen right now.
2026-08750 — Extension of Postponement of Effectiveness for Certain Provisions of Trichloroethylene (TCE); Regulation Under the Toxic Substances Control Act (TSCA)
The EPA is hitting the pause button again on some rules about a chemical called TCE, which is used in workplaces. This means certain limited uses of TCE won’t have to follow new restrictions just yet, while courts review the rules. If you work with TCE, this delay gives you more time before changes kick in, starting May 18, 2026.
