It also supersedes ATSDR’s releases of the former policy as contained in the following publications: De Rosa CT et al. 1997; J Clean Technol Environ Toxicol & Occup Med 6(2):117– 163, and De Rosa CT et al. 1999; Toxicol Ind Health 15(6):552–576. The purpose of this update is to ensure that ATSDR health assessors evaluate dioxin levels that exceed the ATSDR established screening level of 0.05 ppb as described in the ATSDR Public Health Assessment Guidance Manual (PHAGM) (ATSDR 2005). When following the PHAGM, assessors should use the 0.05 ppb value as the comparison value. The comparison value is not, however, a threshold for toxicity and should not be used to predict adverse health effects (ATSDR 2005). This update does not signal a change in ATSDR’s scientific assessment on dioxin toxicity or a change in the ATSDR Minimal Risk Level (MRL). Moreover, the update does not change the assessment of risk associated with dioxin soil levels up to 1 ppb—the level U.S. EPA has set as a preliminary remediation goal for residential soils (EPA 1998).

The announcement of seven PO 00000 Frm 00117 Fmt 4703 Sfmt 4703 toxicological profiles for the nineteenth set was published in the Federal Register on October 25, 2005 (70 FR 61622).

SUPPLEMENTARY INFORMATION: The Superfund Amendments and Reauthorization Act (SARA) (Pub. L. 99–499) amends the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA or Superfund) (42 U.S.C. 9601 et seq. ) by establishing certain statutory requirements for ATSDR and the U.S. Environmental Protection Agency (USEPA) regarding hazardous substances most commonly found at facilities on the National Priorities List (NPL). Among the requirements is a mandate for the Administrator of ATSDR to prepare toxicological profiles for each substance included on the priority list of hazardous substances. This list identifies 275 hazardous substances that ATSDR and U.S. EPA determined pose the most significant potential threat to human health. The availability of the revised list of the 275 priority substances was announced in the Federal Register on March 6, 2008 (73 FR 12178). For previous versions of the list of substances, see Federal Register notices dated April 17, 1987 (52 FR 12866); October 20, 1988 (53 FR 41280); October 26, 1989 (54 FR 43619); October 17, 1990 (55 FR 42067); October 17, 1991 (56 FR 52166); October 28, 1992 (57 FR 48801); February 28, 1994 (59 FR 9486); April 29, 1996 (61 FR 18744; November 17, 1997 (62 FR 61332); October 21, 1999 (64 FR 56792); October 25, 2001 (66 FR 54014); November 7, 2003 (68 FR 63098) and December 7, 2005 (70 FR 72840). The Federal Register notice announcing that the draft toxicological profile for perchlorates was available for public review and comment was published on October 25, 2005(70 FR 61622). After the close of the 90-day public comment period, chemicalspecific comments were addressed, and where appropriate, changes were incorporated into the profile.
