1. Oral comments. Oral comments presented at the meetings should
not be repetitive of previously submitted oral or written comments.
Although, requests to present oral comments are accepted until the date
of the meeting (unless otherwise stated), to the extent that time
permits, interested persons may be permitted by the Chair of FIFRA SAP
to present oral comments at the meeting. Each individual or group
wishing to make brief oral comments to FIFRA SAP is strongly advised to
submit their request to the appropriate DFO listed under FOR FURTHER
INFORMATION CONTACT no later than noon, eastern time, February 8, 2005,
in order to be included on the meeting agenda. The request should
identify the name of the individual making the presentation, the
organization (if any) the individual will represent, and any
requirements for audiovisual equipment (e.g., overhead projector, 35 mm
projector, chalkboard). Oral comments before FIFRA SAP are limited to
approximately 5 minutes unless prior arrangements have been made. In
addition, each speaker should bring 30 copies of his or her comments
and presentation slides for distribution to FIFRA SAP at the meeting.
2. Written comments. Although, submission of written comments are
accepted until the date of the meeting (unless otherwise stated), the
Agency encourages that written comments be submitted, using the
instructions in Unit I.C., no later than noon, eastern time, February
1, 2005, to provide FIFRA SAP the time necessary to consider and review
the written comments. The DFOs listed under FOR FURTHER INFORMATION
CONTACT should be notified that comments have been submitted to the
docket or a courtesy copy of the comments should be provided to the
DFOs. There is no limit on the extent of written comments for
consideration by FIFRA SAP.
3. Seating at the meeting. Seating at the meeting will be on a
first-come basis. Individuals requiring special accommodations at this
meeting, including wheelchair access and assistance for the hearing
impaired, should contact the appropriate DFO at least 5 business days
prior to the meeting using the information under FOR FURTHER
INFORMATION CONTACT so that appropriate arrangements can be made.
4. Request for nominations of prospective candidates for service as
ad hoc members of the FIFRA SAP for this meeting. As part of a broader
process for developing a pool of candidates for each meeting, the FIFRA
SAP staff routinely solicit the stakeholder community for nominations
of prospective candidates for service as ad hoc members of the FIFRA
SAP. Any interested person or organization may nominate qualified
individuals to be considered as prospective candidates for a specific
meeting. Individuals nominated for this meeting should have expertise
in one or more of the following areas: Pharmacokinetic/pharmacodynamic
modeling, toxicology and risk assessment, hazard assessment, exposure
assessment (particularly drinking water), ground water modeling/
monitoring and integration of hazard and exposure. Nominees should be
scientists who have sufficient professional qualifications, including
training and experience, to be capable of providing expert comments on
the scientific issues for this meeting. Nominees should be identified
by name, occupation, position, address, and telephone number.
Nominations should be provided to the appropriate DFO listed under FOR
FURTHER INFORMATION CONTACTon or before January 18, 2005. The Agency
will consider all nominations of prospective candidates for this
meeting that are received on or before this date. However, final
selection of ad hoc members for this meeting is a discretionary
function of the Agency.
The selection of scientists to serve on the FIFRA SAP is based on
the function of the panel and the expertise needed to address the
Agency's charge to the panel. No interested scientists shall be
ineligible to serve by reason of their membership on any other advisory
committee to a Federal department or agency or their employment by a
Federal department or agency (except the EPA). Other factors considered
during the selection process include availability of the potential
panel member to fully participate in the panel's reviews, absence of
any conflicts of interest or appearance of lack of impartiality,
independence with respect to the matters under review, and lack of
bias. Though financial conflicts of interest, the appearance of lack of
impartiality, lack of independence, and bias may result in
disqualification, the absence of such concerns does not assure that a
candidate will be selected to serve on the FIFRA SAP. Numerous
qualified candidates are identified for each panel. Therefore,
selection decisions involve carefully weighing a number of factors
including the candidates' areas of expertise and professional
qualifications and achieving an overall balance of different scientific
perspectives on the panel. In order to have the collective breadth of
experience needed to address the Agency's charge for this meeting, the
Agency anticipates selecting approximately 12 ad hoc scientists.
If a prospective candidate for service on the FIFRA SAP is
considered for participation in a particular session, the candidate is
subject to the provisions of 5 CFR part 2634, Executive Branch
[[Page 1242]]
Financial Disclosure, as supplemented by EPA in 5 CFR part 6401. As
such, the FIFRA SAP candidate is required to submit a Confidential
Financial Disclosure Form for Special Government Employees Serving on
Federal Advisory Committees at EPA Form 3110-48 [5-02]) which shall
fully disclose, among other financial interests, the candidate's
employment, stocks, and bonds, and where applicable, sources of
research support. EPA will evaluate the candidate's financial
disclosure form to assess that there are no financial conflicts of
interest, no appearance of lack of impartiality and no prior
involvement with the development of the documents under consideration
(including previous scientific peer review) before the candidate is
considered further for service on the FIFRA SAP.
Those who are selected from the pool of prospective candidates will
be asked to attend the public meetings and to participate in the
discussion of key issues and assumptions at these meetings. In
addition, they will be asked to review and to help finalize the meeting
minutes. The list of FIFRA SAP members participating at this meeting
will be posted on the FIFRA SAP web site or may be obtained by
contacting the PIRIB at the address or telephone number listed in Unit
I.
II. Background
A. Purpose of the FIFRA SAP
Amendments to FIFRA enacted November 28, 1975 (7 U.S.C. 136w(d)),
include a requirement under section 25(d) of FIFRA that notices of
intent to cancel or reclassify pesticide registrations pursuant to
section 6(b)(2) of FIFRA, as well as proposed and final forms of
regulations pursuant to section 25(a) of FIFRA, be submitted to a SAP
prior to being made public or issued to a registrant. In accordance
with section 25(d) of FIFRA, the FIFRA SAP is to have an opportunity to
comment on the health and environmental impact of such actions. The
FIFRA SAP also, shall make comments, evaluations, and recommendations
for operating guidelines to improve the effectiveness and quality of
analyses made by Agency scientists. Members are scientists who have
sufficient professional qualifications, including training and
experience, to be capable of providing expert comments as to the impact
on health and the environment of regulatory actions under sections 6(b)
and 25(a) of FIFRA. The Deputy Administrator appoints seven individuals
to serve on the FIFRA SAP for staggered terms of 4 years, based on
recommendations from the National Institutes of Health and the National
Science Foundation.
Section 104 of FQPA (Public Law 104-170) established the FQPA
Science Review Board (SRB). These scientists shall be available to the
FIFRA SAP on an ad hoc basis to assist in reviews conducted by the
FIFRA SAP.
B. Public Meeting
The Food, Quality Protection Act of 1996 amended the Federal
Insecticide, Fugicide, and Rodenticide Act and the Federal Food, Drug,
and Cosmetic Act. One of the major changes is the requirement that EPA
consider risk posed by pesticides acting by a common mechanism of
toxicity. For such groups of pesticides, EPA's Office of Pesticide
Programs (OPP) has treated cumulative risk, under FQPA, as the risk of
a common toxic effect associated with concurrent exposure by all
relevant pathways and routes. EPA has determined that the group of
pesticides known as the N-methyl carbamate pesticide share a common
mechanism of toxicity, and should be treated as a common mechanism
group. Therefore, EPA is conducting a cumulative risk assessment that
will include the chemicals comprising this group.
At the meeting being announced by this notice, EPA plans to discuss
key issues related to development of the cumulative risk assessment for
the N-methyl carbamate pesticides. Those issues are as follows: Hazard
assessment, pharmacokinetic/pharmacodynamic (PBPK/PD) modeling of
carbaryl, drinking water exposure assessment, and the integration of
hazard and exposure information.
C. Hazard assessment
EPA acknowledges that there are toxicological characteristics
unique to the N-methyl carbamates which need to be considered in a
cumulative risk assessment for this group. Specifically, the mechanism
of action for this group of pesticides is carbamylation of the
acetylcholinesterase (AChE) active site. This chemical change is
reversible, allowing for relatively rapid recovery from inhibition. OPP
is collaborating with laboratory scientists and statisticians from
EPA's National Health and Environmental Effects Research Laboratory
(NHEERL) to evaluate biological and empirical aspects of recovery. EPA
expects to solicit comment from the SAP on specific issues related to
dose-response modeling of AChE data, empirical estimation of time to
recovery, and the impact of the laboratory method used to measure AChE
inhibition on estimates of relative potency.
1. PBPK/PD modeling for carbaryl. OPP is collaborating with
scientists from EPA's National Exposure Research Laboratory (NERL) to
develop a PBPK/PD model for carbaryl within the Exposure Related Dose
Estimating Model (ERDEM) Platform (Blancato et al., 2002; Okino et al.
2004). The carbaryl model will form the basic structure of a
generalized model for the N-methyl carbamates. A Quantitative Structure
Activity Relationship (QSAR) database of physicochemical descriptors
and provisional PK and PD parameter values has been assembled for
selected N-methyl carbamates. The completeness and representativeness
of the QSAR database will influence the application of the PBPK/PD
model for use in the cumulative risk assessment of the N-methyl
carbamates. EPA will solicit comment from the SAP on specific aspects
of the appropriate use of ERDEM for this cumulative risk assessment.
2. Drinking water exposure assessment. Unlike the organophosphate
(OP) cumulative risk assessment where the only anticipated exposure to
OP pesticides in drinking water was expected to be from surface water
sources, EPA must consider both surface water and ground water sources
of drinking water for the N-methyl carbamates. OPP will solicit comment
from the SAP on the use of one or more existing ground water models to
provide a pilot drinking water exposure assessment for the N-methyl
carbamates. OPP also expects to request feedback from the Panel on
approaches for refining regional drinking water exposures in the event
that such exposure from surface water and/or ground water sources
contributes substantially to the cumulative exposure in one or more
regions.
3. Integration of hazard and exposure assessment. EPA will present
to the SAP a pilot cumulative analysis of food, water, and residential
exposure using three different exposure models: LifeLine, CARES, and
Calendex. The presentation will also include a discussion of the unique
challenges related to rapid recovery from AChE inhibition posed by this
group of pesticides and different approaches for considering these
characteristics in the quantitative estimates of cumulative risk. EPA
expects to request the panel to provide comment on potential approaches
for integrating hazard and exposure for this group and specifically
characterizing recovery in risk estimates.
