II. Background

A. Purpose of the Meeting?

    This 4-day meeting concerns several scientific issues undergoing
consideration within the EPA/Office of Pesticide Programs (OPP). The
four session topics to be addressed during the 4-day meeting are
indicated as follows:
    The first session will focus on assessing the potential
allergenicity of non-digestible proteins expressed as plant-pesticides.
The specific case in question concerns the Cry9C insecticidal protein
derived from Bacillus thuringiensis and expressed in field corn. The
Agency is asking questions on the use of amino acid homology, the brown
Norway rat model for food allergenicity and other subjects with regards
to the assessment for potential allergenicity.
    The second session will address the decomposition module in the
Dietary Exposure Evaluation Model (DEEM) software. In estimating
dietary exposure to pesticides, the Agency uses several sources for
monitoring data of pesticide residues in foods. These monitoring data,
however, are in the form of pesticide residues on composited samples
and do not directly represent concentrations of pesticide residues in
single food items. For acute dietary exposure estimation, it is the
residues in single items of produce that are of interest rather than
``average'' residues measured in composited samples. The decomposition
module in the DEEM software uses a statistical procedure in order to
``decomposite'' composited monitoring data to estimate residues in
single items. The purpose of this presentation is to describe the
decomposition component of the software.
    The second session will also include a presentation of the MaxLIP
(Maximum Likelihood Imputation Procedure) Pesticide residue
decompositing procedure and software. For acute dietary exposure
estimation, it is the residues in single items of produce that are of
interest rather than ``average'' residues measured in composited
samples. The MaxLIP software uses a maximum likelihood estimation
procedure in order to ``decomposite'' composited monitoring data to
estimate residues in single items.
    The third session will focus on the Dietary Exposure Evaluation
Model (DEEM). A major component of assessing the risks of pesticide
substances is the estimation of dietary exposure to pesticide residues
in foods. The Agency currently uses the DEEM exposure assessment
software in conducting its dietary exposure and risk assessment. The
purpose of this session is to describe the components and methodologies
used by the DEEM software.
    The last session is to provide the FIFRA SAP with a progress report
on the Agency's efforts to implement the drinking water component of
the FQPA aggregate exposure assessment. Aggregate exposure is defined
to encompass multiple potential sources of exposure to pesticides and
includes exposure from pesticide residues in food, in drinking water
and in the home. In order to combine the drinking water component with
the population based distribution of pesticide residues on food items
in a statistically rigorous manner, the data should be developed with
the same general structure. In this way, the Monte Carlo procedure used
for the risk assessment for food stuffs can be extended to the drinking
water component.
    The Agency will outline the basic steps envisioned in developing
national, population-weighted distributions of pesticide residues in
drinking water and aggregating them with distributions in food. These
steps include development of distributions of pesticide drinking water
concentration values across surface water/drinking water intake
locations, consideration of the impact of treatment by a water utility,
and development of methodologies to combine the adjusted distributions
with the distribution of pesticide residues on food items. The
presentation on development of distributions of drinking water
concentrations will describe a process using measured data with a
computer modeling/analysis overlay. The details of how the Agency will
consider the effects of treatment will be largely addressed in a future
FIFRA SAP meeting.

B. Panel Report

    Copies of the Panel's report of their recommendations will be
available approximately 45 working days after the meeting, and will be
posted on the FIFRA SAP web site or may be obtained by contacting the
