the Environmental Protection Agency (EPA) with regard to hazardous

substances which are most commonly found at facilities on the CERCLA

National Priorities List (NPL). Among these statutory requirements is a

mandate for the Administrator of ATSDR to prepare toxicological

profiles for each substance included on the priority lists of hazardous

substances. These lists identified 275 hazardous substances that ATSDR

and EPA determined pose the most significant potential threat to
