Friday, excluding legal holidays. The PIRIB telephone number is (703)
305-5805.
III. Sessions Overview
Session I will be the review of issues pertaining to the assessment
of residential exposure to pesticides. When estimating aggregate
exposure to a pesticide substance, the Agency includes exposures that
may occur following use of the pesticide in residential or other non-
occupational settings. This session will focus on several key issues
that pertain to improving procedures for estimating exposure to
pesticides from use in residential or other non-occupational settings
and in revising its standard operating procedures for residential
exposure assessments. The issues include: (1) Calculating percent
dislodgeability of available pesticide residues from lawns, indoor
surfaces, and pets; (2) use of choreographed activities as surrogates
for estimating a child's dermal exposure; (3) characterizing hand (or
object)-to-mouth activities; (4) calculating exposure to pesticides
that may result from track-in, drift, bathing or showering; and (5)
calculating exposure from use of pesticides in schools, day-care
centers, and other public places.
Session II provides a review of an aggregate exposure assessment
tool being developed through a cooperative agreement with Hampshire
Research Institute (HRI). The Agency is working collaboratively under
this cooperative agreement with HRI to create a tool that is publicly
available, open software with no hidden logic; uses HRI's micro-
exposure event analysis method; incorporates an object-oriented design
that allows for continuing refinement and improvement; and includes a
design that addresses known future requirements for pesticide analysis,
such as cumulative risk assessment. The purpose of this session is for
Agency scientists to consult with the SAP regarding the current status
and future development options of this tool.
Session III emphasizes the identification of carbamate pesticides
that have a common mechanism of toxicity. The identification of
pesticides and other substances that cause a common toxic effect by a
common mechanism is the first step of the cumulative risk assessment
process (as required by the FQPA). The Agency has developed a framework
for identifying chemicals that have a common mechanism of toxicity
(February 5, 1999, 64 FR 5796) (FRL-6060-7). This session will describe
the results of the Agency's effort to determine whether (1) carbamate
pesticides cause a common toxic effect by a common mechanism and (2) if
any carbamate pesticides share a common mechanism of toxicity with
organophosphorus pesticides.
Session IV addresses issues pertaining to cumulating hazard for
conducting cumulative risk assessments for pesticides that have a
common mechanism of toxicity. The Agency is preparing guidance for
assessing cumulative risk in support of the Food Quality Protection Act
1996. This session will focus on key hazard and dose response issues
involved with cumulating risk from exposure to two or more chemicals
that are toxic by a common mechanism. These issues deal with, for
example: (1) End point selection; (2) application of adjustment and
group uncertainty factors; (3) interspecies dose adjustments; (4)
utilization of dose-response data and selection of a point of
departure; and (5) methods for combining toxicity data. In addition,
science policy issues such as assumptions concerning dose addition and
dose response relationships will be presented. The Agency needs input
from the SAP and the public on the hazard and toxicological issues that
concern cumulative risk assessment.
Session V concerns the review of the American Cyanamid Company's
April 22, 1999 probabilistic assessment (MRID No. 448098-01) for
chlorfenapyr. In December 1994, the Agency received a
[[Page 48396]]
request for registration for the use of the pyrrole insecticide,
chlorfenapyr on cotton. As a part of the registration package, American
Cyanamid Company submitted a probabilistic assessment. The Agency is
seeking SAP input regarding: (1) American Cyanamid's probabilistic
assessment and how it may be improved; (2) the Agency's review of the
assessment; and (3) the utility of using this assessment to
characterize the risk of chlorfenapyr use on cotton to birds in cotton
agroenvironments.
