SUPPLEMENTARY INFORMATION:
I. Purpose of the Meeting
This SAP meeting includes five distinct sessions. The first session
will be the review of a risk assessment of a biopesticide and possible
human opportunistic pathogen. Some microorganisms used for controlling
pests may be opportunistic human pathogens, or closely related to
opportunistic pathogens. Opportunistic pathogens are microbes that are
capable of causing disease only in people who are immunocompromized or
are otherwise especially susceptible. A critical issue concerns the
pathogenic strains proposed for registration as biopesticides, since
these strains are typically isolated from the environment, for example
agricultural fields, rather than as clinical specimens. As such, these
strains have no history of actually causing disease and may not be able
to do so. Criteria for relatedness between clinical strains and
biocontrol strains and the ability to predict pathogenicity of the
biocontrol strains is therefore vital.
The Agency requests the SAP to address the sufficiency of current
tests used to consider the risk from opportunistic pathogens to
immunocompromized populations. Burkholderia cepacia, a biopesticide
which may cause fatal infections with cystic fibrosis and chronic
granulomatous disease, will be used as a test case to examine the
adequacy of animal models, taxonomic criteria, and criteria using known
virulence genes as predictors of the pathogenic potential of individual
strains, as well as issues related to the importance of levels of
exposure and the nature of susceptible populations.
The second session will be a consultation on a study protocol
design to assess acute neurotoxicity studies following oral
administration of pesticides. Recently, several acute neurotoxicity
studies have been submitted to the Agency employing this protocol
design. This novel design deviates from the standard Agency acute
developmental neurotoxicity protocols. The primary difference is that
the test substance is administered in the diet compared to being
administered as a bolus dose in the standard Agency study design. The
purpose of this session is to consult with the SAP regarding issues
pertaining to this new design.
The third session will be a review of issues pertaining to the
assessment of exposure to pesticides in residential and other non-
occupational settings. 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 children'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.
The fourth session concerns the review of the Agency's chlorfenapyr
ecological risk assessment. In December, 1994, the Agency received a
request for registration for the use of the pyrrole insecticide
chlorfenapyr on cotton. The Agency is seeking SAP input regarding the
use of available data to characterize the risk of chlorfenapyr use on
cotton to birds in cotton agroenvironments. The Agency requests SAP
comments on its assessment of avian risks and is seeking
[[Page 36354]]
SAP suggestions for how the Agency might use probabilistic risk
assessment techniques to improve its risk assessment. Specifically, the
Agency is seeking guidance on the geographic scale of a probabilistic
risk assessment. The SAP will be queried on what data on chlorfenapyr
fate, residues, effects and cotton agroenvironments would be necessary
to accommodate extrapolations of risks to scales beyond the treated
agroenvironment to much larger scales.
The final session will be a review of pesticide spray drift data
from ground hydraulic and orchard air blast applications. The purpose
of this session is to examine the validity of an approach developed to
place bounds on the Spray Drift Task Force data for ground hydraulic
boom and orchard air blast spraying applications. Curves developed from
bounds are intended to be used in environmental exposure assessments to
estimate deposition over a range of distances, replacing the use of a
fixed estimate. The proposed bounding method is intended to be
adaptable to allow the addition of data from new or existing
application methods.

written comments in lieu of oral presentations. Persons wishing to make
oral and/or written statements should notify either Larry Dorsey or
Paul Lewis and submit 40 copies of the summary information. The Agency
encourages that written statements be submitted before the meeting to
provide Panel Members the time necessary to consider and review the
comments.
