SUPPLEMENTARY INFORMATION:

I. Information About the Project/Document

    U.S. EPA's Ecological Risk Assessment Support Center (ERASC) is a 
knowledge center that provides technical information and addresses 
scientific questions on topics relevant to ecological risk assessment 
at hazardous waste sites for EPA's Office of Solid Waste and Emergency 
Response (OSWER) and Regional Superfund/Resource Conservation and 
Recovery Act (RCRA) staff. The topics are submitted by users in the 
program office and regions. The ERASC is managed by the Office of 
Research and Development's (ORD's) National Center for Environmental 
Assessment and is located in Cincinnati, Ohio.
    The ERASC recently completed an external review draft of the 
document titled, ``Application of Equilibrium Partitioning Theory to 
Soil PAH Contamination''. It addresses the issue of whether equilibrium 
partitioning techniques can be used to predict the toxicity of PAH 
mixtures in soil.
