Agency for Toxic Substances and Disease Registry 2018 – Federal Register Recent Federal Regulation Documents

The Agency for Toxic Substances and Disease Registry (ATSDR), within the Department of Health and Human Services (HHS) announces the availability of Set 29 Draft Toxicological Profiles for review and comment. All toxicological profiles issued as ``Drafts for Public Comment'' represent ATSDR's best efforts to provide important toxicological information on priority hazardous substances. ATSDR is seeking public comments and additional information or reports on studies about the health effects of Tribufos, Bromodichloromethane, Bromomethane, and 2-Hexanone for review and potential inclusion in the profiles. Although ATSDR considers key studies for these substances during the profile development process, this document solicits any relevant, additional information. ATSDR will evaluate the quality and relevance of such data or studies for possible inclusion into the profile. ATSDR also seeks comments on the organization and format of the Toxicological Profile for Bromodichloromethane. In an effort to improve the usability of the profiles, ATSDR recently made content and organizational changes based on user feedback, as well as data identifying the most used profile content. Changes include: Removing redundant content; adding summary figures and tables to Chapters 1, 2, 5, and 6 that did not exist in previous Toxicological Profiles; and reformatting the Levels of Significant Exposure (LSE) tables in Chapter 2. ATSDR has only applied the changes to the Draft Toxicological Profile for Bromodichloromethane, but intends to use the new format for future profiles. Specifically, ATSDR would like to know: (1) Does the chapter organization make it easier for you to find the information you need? For example, are you satisfied with the organization of the health effects chapter by organ system rather than exposure route? (2) Are the new tables and figures clear and useful? Do they make the Toxicological Profile easier to read? (3) If you have previously used any Toxicological Profile(s) for your work, which parts or content are the most useful to you, and what do you use it for? (4) Does the profile contain all of the information you need? If no, please elaborate on what additional information would be helpful. (5) Is there information you would like to see in the profile that is not currently included? If yes, please elaborate on the additional information you would like to see in the profile. ATSDR remains committed to providing a public comment period for these documents as a means to provide the best service to the public regarding public health.

The Agency for Toxic Substances and Disease Registry (ATSDR) within the Department of Health and Human Services is initiating the development of another set of Toxicological Profiles. This notice solicits public nominations of substances for ATSDR to evaluate for Toxicological Profile development. ATSDR will consider nominations from the Substance Priority List, as well as any non-Comprehensive Environmental Response, Compensation, and Liability Act of 1980 (CERLA) substances that may have public health implications, on the basis of ATSDR's authority to prepare Toxicological Profiles for substances not found at sites on the National Priorities List. The agency will do so in order to ``. . . establish and maintain inventory of literature, research, and studies on the health effects of toxic substances'', to respond to requests for consultation, and to support the site-specific response actions conducted by ATSDR, as otherwise necessary.
