SUPPLEMENTARY INFORMATION:

In the “Availability of Draft Toxicological Profile for Xylene” notice that appeared in the May 5, 2026 Federal Register (91 FR 24239), we solicited public comments on the draft updated toxicological profile for xylene. This action provides the public and interested organizations an opportunity to submit comments and any additional relevant information, including reports or studies on the health effects associated with xylene exposure, for ATSDR's review.

ATSDR received a request to extend the comment period by 90 days. We considered the request but determined that such an extension would not allow the agency to finalize this action within the necessary timeframe. Accordingly, ATSDR is extending the comment period by 30 days to provide additional time for interested persons to submit comments while allowing the agency to proceed with timely finalization of the document.

Donata Green,

Associate Director, Office of Policy, Planning and Partnerships, Agency for Toxic Substances and Disease Registry.
