Nomination Summary for Xylenes (N20320)
Nominated Substances: Xylenes (mixed)
Nomination Date: 08/07/2002
Rationale: Section 104(i)(5) of CERCLA, as amended [by SARA, 1986], directs the Administrator of ATSDR (in consultation with the Administrator of EPA and agencies and programs of the Public Health Service) to assess whether adequate information on the health effects of hazardous substances found at National Priorities List waste sites is available. Where adequate information is not available, ATSDR, in conjunction with the NTP, is required to assure the initiation of a program of research designed to determine the health effects of such substances. Under the Substance Specific Applied Research Program, ATSDR has identified priority data needs for 60 hazardous substances and transmitted a subset of these to the NTP for consideration in its toxicology testing program.
