Key takeaway
What This Development Means
EPA has listed carbon tetrachloride TSCA amendments under RIN 2070-AL42 at the proposed-rule stage. It has not published a proposal, so the December 2024 risk-management rule remains the current legal baseline.
Has EPA Already Changed The Carbon Tetrachloride TSCA Rule?
No. The Unified Agenda entry announces a rulemaking intention and says EPA will solicit comment through a future notice of proposed rulemaking. It creates no new exemption, prohibition or deadline. The December 2024 rule remains the legal baseline unless formally amended or affected by litigation.
When Will The EPA Carbon Tetrachloride Amendments Be Final?
The agenda lists a final rule for September 2027, but Unified Agenda dates are planning estimates and can change. It also lists a July 2026 proposal milestone without a Federal Register citation, so stakeholders should track the docket for an actual published proposal.
Source basis: Reginfo.gov, US Environmental Protection Agency RIN 2070-AL42 (14 August 2026)
The US Environmental Protection Agency has placed carbon tetrachloride TSCA amendments on the 2026 Unified Agenda under new Regulatory Information Number 2070-AL42. The entry signals reconsideration of aspects of the December 2024 Toxic Substances Control Act section 6 risk-management rule.
The agenda entry does not amend the law or open a comment period. Businesses should continue following current requirements while preserving exposure, cost and use evidence for a future proposal.
EPA Carbon Tetrachloride Amendments Remain Pre-Proposal
EPA says it is considering changes to previously promulgated provisions addressing the unreasonable risk presented by carbon tetrachloride. The agency intends to solicit comment through a notice of proposed rulemaking. The agenda lists the action at proposed-rule stage and describes it as the first publication of this rulemaking.
The current rule requires workplace exposure controls for many conditions of use, prohibits specified industrial and commercial uses and imposes related requirements. Several legal challenges began in 2025. EPA now says the rule should be reconsidered while acknowledging its statutory duty to eliminate the unreasonable risk identified through the TSCA evaluation.
What changed is the creation of a distinct amendment rulemaking and public timetable. The December 2024 rule remains unchanged unless EPA completes a legally effective amendment or a court changes its operation. The agenda's July 2026 proposal date is a planning entry, not evidence that a notice has been published.
Chemical, Waste And Worker-Safety Stakeholders Are Affected
The agenda identifies chemical manufacturing, petrochemicals, industrial gases, plastics and resins, pesticides, cement, non-ferrous metals and waste treatment among affected sectors. Laboratories, distributors and importers may also depend on the final treatment of workplace chemical protection programmes, prohibited uses, dermal controls, respirators and fume hoods.
Companies face a two-track risk. Preparing only for possible deregulation could expose workers or breach current duties, while ignoring reconsideration could leave technical evidence out of a future comment process. The defensible approach is to maintain current controls and separately document costs, feasibility and exposure performance.
Carbon tetrachloride sits within the broader chlorinated solvents risk picture. Foresight's earlier TSCA compliance extension article covers a different March 2026 action and should not be treated as this new RIN.
What Organisations Should Do Now
Facilities should confirm current carbon tetrachloride conditions of use, compliance dates, exposure controls, downstream notifications and record-keeping. Legal teams should track docket EPA-HQ-OPPT-2020-0592 and RIN 2070-AL42 for an actual notice. Industry and worker representatives should prepare evidence but wait for a formal proposal before submitting comments.
Procurement teams should ask suppliers whether reformulation, substitution or discontinued uses could affect availability, specifications or contractual assurances while the amendment process remains uncertain and current carbon tetrachloride duties continue to apply.
Summary
EPA has opened a rulemaking path, not changed the carbon tetrachloride rule. The December 2024 requirements remain the legal baseline. Businesses should maintain current controls, map each condition of use and monitor RIN 2070-AL42 for a formal proposal and comment period.
