SUPPLEMENTARY INFORMATION: This draft guidance document outlines 
approaches for developing factors for inter- and intra-species 
extrapolation based on data describing toxicokinetic and/or 
toxicodynamic properties of particular agent(s). It was developed to 
provide guidance for EPA staff in evaluating such data and/or 
information and to provide information to the regulated community and 
other interested parties about deriving and implementing extrapolation 
factors derived from data instead of defaults.
