| E6-22388 | Update to ATSDR Policy Guideline for Dioxins and Dioxin-Like Compounds in Residential Soil | Notice | ATSDR is seeking public comment on the draft revision of its 1998 Policy Guideline for Dioxins and Dioxin-Like Compounds in Residential Soil. The policy is intended to assist health assessors who must evaluate the public health implications of dioxin and dioxin-like compounds (e.g., 2,3,7,8-tetrachlorodibenzo-p-dioxin [TCDD], chlorinated dibenzodioxins [CDDs], chlorinated dibenzofurans [CDFs], and other structurally related groups of chemicals from the family of halogenated aromatic hydrocarbons) in residential soils near or on hazardous waste sites. The 1998 policy established a screening level of 0.05 ppb TEQ (50 ppt), an evaluation level (>0.05 ppb TEQ, <1 ppb), and an action level of 1 ppb TEQ (1,000 ppt) for dioxins in residential soil. ATSDR revised the 1998 policy because it has been used inconsistently over the past eight years. The ATSDR "action" level has been misinterpreted by health assessors and others as ... (1) A soil concentration that defines a public health hazard, (2) an ATSDR clean-up level which implies the need for site remediation, and (3) an initial screening level that defines a safe level of exposure, below which there is no public health concern. In addition, the "action" level triggered a set of "potential public health actions", including surveillance, research, health studies, community education, and exposure investigations. However, ATSDR believes that these actions could be considered in some circumstances when the 1 ppb level in soil is not exceeded. In response to these concerns ATSDR has updated its Policy Guideline for Dioxins and Dioxin-Like Compounds in Residential Soil. The key elements in the updated ATSDR Policy Guideline for Dioxins and Dioxin-Like Compounds in Residential Soil are as follows: <bullet> Deletion of the 1 ppb action level as the criteria for taking specific public health actions. The 1-ppb dioxin soil concentration should not be used as a comparison value for defining public health hazards in public health assessments and consultations. The 1-ppb action level can be cited by health assessors as the Superfund Dioxin Cleanup policy criteria (EPA 1989, 1998). | 2006-12-29 | 2006 | 12 | https://www.federalregister.gov/documents/2006/12/29/E6-22388/update-to-atsdr-policy-guideline-for-dioxins-and-dioxin-like-compounds-in-residential-soil | https://www.govinfo.gov/content/pkg/FR-2006-12-29/pdf/E6-22388.pdf | Health and Human Services Department; Agency for Toxic Substances and Disease Registry | 221,7 | ATSDR is seeking public comment on the draft revision of its 1998 Policy Guideline for Dioxins and Dioxin-Like Compounds in Residential Soil.
