EPA proposes TSCA SNURs Batch 26-1 for chemical substances
The EPA has proposed Significant New Use Rules (SNURs) under TSCA Section 5 for chemical substances that were the subject of premanufacture notices (PMNs) and TSCA Orders. The SNURs would require persons intending to manufacture or process these chemical substances for activities designated as significant new uses to notify EPA at least 90 days before commencing that activity. This is Batch 26-1 of proposed SNURs.

EPA will regulate 15 uses of 1,2-dichloroethane (TSCA §6(a) risk management rulemaking announced)
EPA announced it will move forward with TSCA section 6(a) risk management to regulate 15 industrial and commercial conditions of use of 1,2-dichloroethane (1,2‑DCA), based on EPA’s final risk evaluation finding unreasonable risk to workers in 15 of 20 conditions of use (driven by inhalation and dermal exposure). EPA stated it did not identify unreasonable risk to consumers, the general population (including fish-consuming/Tribal communities), or the environment under evaluated conditions of use. Compliance teams should anticipate forthcoming workplace-focused restrictions/controls for affected 1,2‑DCA uses and monitor the referenced docket activity for proposed requirements, timelines, and any exemptions.

EPA releases list of expiring TSCA CBI claims and launches CDX process for CBI claim extension requests
EPA published a rolling public list of TSCA Confidential Business Information (CBI) claims scheduled to expire (including claims expiring between June 22, 2026 and July 31, 2026) and stated it will refresh the list monthly. EPA also described a new electronic extension-request process in EPA’s Central Data Exchange (CDX) using a dedicated tool (TSCA Section 14(e) CBI Claim Extension Request). Companies must submit extension requests with substantiation no later than 30 days before claim expiration to maintain confidentiality protections; otherwise, EPA may no longer be required to protect the information from disclosure. Compliance teams should inventory TSCA submissions with CBI claims, monitor the monthly expiring-claims list, and prepare CDX extension filings within EPA’s stated timing window.
