Methodology for Deriving Ambient Water Quality Criteria for the Protection of Human Health; Technical Support Document, Volume 3: Development of Site-Specific Bioaccumulation Factors

摘要

In 2000, EPA announced the availability of final revisions to the Methodology for Deriving Ambient Water Quality Criteria for the Protection of Human Health (2000) (hereafter "2000 Human Health Methodology") published pursuant to section 304(a) (1) of the Clean Water Act (CWA). Along with the 2000 Human Health Methodology, EPA committed to publishing several technical support documents to provide additional detail to the Methodology document, including two documents that describe the development of bioaccumulation factors for use in ambient water quality criteria calculations. In 2003, EPA announced the release of the Technical Support Document Volume 2: Development of National Bioaccumulation Factors (hereafter "National BAF TSD"). Today, the Agency is releasing the Technical Support Document, Volume 3: Development of Site-Specific Bioaccumulation Factors (hereafter "Site-Specific BAF TSD") that accompanies the Methodology and the National BAF TSD. EPA accepted scientific views on the draft document in two separate Federal Register Notices. The National BAF TSD contains technical details on how EPA develops national bioaccumulation factors for use in deriving national recommended
