Problem Formulation for Human Health Risk Assessments of
Pathogens in Land-Applied Biosolids
AGENCY: Environmental Protection Agency (EPA).
ACTION: Notice of availability.
-----------------------------------------------------------------------
SUMMARY: EPA is announcing the availability of a final report titled,
``Problem Formulation for Human Health Risk Assessments of Pathogens in
Land-Applied Biosolids'' EPA/600/R-08/035F, which was prepared by the
National Center for Environmental Assessment (NCEA) within EPA's Office
of Research and Development (ORD).
DATES: This document will be available on or about May 26, 2011.
ADDRESSES: The document will be available electronically through the
NCEA Web site at http://www.epa.gov/ncea. A limited number of paper
copies will be available from the EPA's National Service Center for
Environmental Publications (NSCEP), P.O. Box 42419, Cincinnati, OH
45242; telephone: 1-800-490-9198; facsimile: 301-604-3408; e-mail:

SUPPLEMENTARY INFORMATION: This document may be useful to Federal,
State or local risk assessors and managers, contractors, or other
parties interested in conducting microbial risk assessments on land-
applied biosolids. In particular, this document provides concepts and
planning considerations for conducting human health risk assessments on
potential pathogens in land-applied biosolids. The document does not
represent guidance, nor does it constitute a risk assessment for
pathogens in land-applied biosolids. As one component of U.S. EPA's
action plan for its biosolids program (http://cfpub.epa.gov/ncea/cfm/recordisplay.cfm?deid=231964), this document summarizes the existing
literature; defines critical pathogen stressors; develops conceptual
models linking the most likely stressors, pathways and health responses
of concern; evaluates the overall quality and utility of available risk
assessment data; highlights existing tools and methodologies; and
provides an outline of an Analysis Plan that identifies gaps in
knowledge and research and methods needed to provide more
scientifically defensible assessments relevant to U.S. EPA's decision
needs. The document has been updated and revised by EPA based on
comments received from the public and an independent, external panel of
scientific experts (73 FR 54400).

Acting Director, National Center for Environmental Assessment.
