SUPPLEMENTARY INFORMATION: These toxicological profiles were developed

by ATSDR for hazardous substances at Department of Energy (DOE) waste

sites under Section 104(i) (3) and (5) of the Comprehensive

Environmental Response, Compensation, and Liability Act of 1980 (CERCLA

or Superfund). This public law directed ATSDR to prepare toxicological

profiles for hazardous substances most commonly found at facilities on

the CERCLA National Priorities List (NPL) and that pose the most

significant potential threat to human health, as determined by ATSDR

and the EPA. The current ATSDR priority list of hazardous substances at

DOE NPL sites was announced in the Federal Register on July 24, 1996

(61 FR 38451).

Although key studies for each of the substances were considered

during the profile development process, this Federal Register notice

seeks to solicit any additional studies, particularly unpublished data

and ongoing studies, which will be evaluated for possible addition to

the profiles now or in the future.

The following draft toxicological profiles will be made available

to the public on or about October 17, 1997.
