**SUPPLEMENTARY INFORMATION:**
In the “Availability of Five Draft Toxicological Profiles” notice that appeared in the November 8, 2024 *Federal Register* (89 FR 88772), we solicited public comments on drafts of five updated toxicological profiles: benzene, carbon disulfide, cyanide, thallium, and chlorinated dibenzo- *p* -dioxins. This action is necessary as this is the opportunity for members of the public and organizations to submit comments on drafts of the profiles. The intended effect of this action is to ensure that the public can note any pertinent additional information or reports on studies about the health effects caused by exposure to the substances covered in these five profiles for review.
We have received requests from interested parties to extend the comment period. Therefore, we are extending the comment period for an additional seven days.
