    2. Electronic access. You may access this Federal Register document 
electronically through the EPA Internet under the ``Federal Register'' 
listings at http://www.epa.gov/fedrgstr/.
    EPA's position paper, charge/questions to FIFRA SAP, FIFRA SAP 
composition (i.e., members and consultants for this meeting), and the 
meeting agenda will be available as soon as possible, but no later than 
mid-to late May 2005. In addition, the Agency may provide additional 
background documents as the materials become available. You may obtain 
electronic copies of these documents, and certain other related 
documents that might be available electronically, from the FIFRA SAP 
Internet Home Page at http://www.epa.gov/scipoly/sap.
    An electronic version of the public docket is available through 
EPA's electronic public docket and comment system, EPA Dockets. You may 
use EPA Dockets at http://www.epa.gov/edocket/ to submit or view public 
comments, access the index listing of the contents of the official 
public docket, and to access those documents in the public docket that 
are available electronically. Once in the system, select ``search,'' 
then key in the appropriate docket ID number.
    Certain types of information will not be placed in EPA Dockets. 
Information claimed as CBI and other information whose disclosure is 
restricted by statute, which is not included in the official public 
docket, will not be available for public viewing in EPA's electronic 
public docket. EPA's policy is that copyrighted material will not be 
placed in EPA's electronic public docket but will be available only in 
printed, paper form in the official public docket. To the extent 
feasible, publicly available docket materials will be made available in 
EPA's electronic public docket. When a document is selected from the 
index list in EPA Dockets, the system will identify whether the 
document is available for viewing in EPA's electronic public docket. 
Although not all docket materials may be available electronically, you 
may still access any of the publicly available docket materials through 
the docket facility identified in Unit I.B.1. EPA intends to work 
towards providing electronic access to all of the publicly available 
docket materials through EPA's electronic public docket.
    For public commenters, it is important to note that EPA's policy is 
that public comments, whether submitted electronically or in paper, 
will be made available for public viewing in EPA's electronic public 
docket as EPA receives them and without change, unless the comment 
contains copyrighted material, CBI, or other information whose 
disclosure is restricted by statute. When EPA identifies a comment 
containing copyrighted material, EPA will provide a reference to that 
material in the version of the comment that is placed in EPA's 
electronic public docket. The entire printed comment, including the 
copyrighted material, will be available in the public docket.
    Public comments submitted on computer disks that are mailed or 
delivered to the docket will be transferred to EPA's electronic public 
docket. Public comments in hard copy that are mailed or delivered to 
the docket will be scanned and placed in EPA's electronic public 
docket. Where practical, physical objects will be photographed, and the 
photograph will be placed in EPA's electronic public docket along with 
a brief description written by the docket staff.

C. How and to Whom Do I Submit Comments?

    You may submit comments electronically (preferred), through hand 
delivery/courier, or by mail. To ensure proper receipt by EPA, identify 
the appropriate docket ID number in the subject line on the first page 
of your comment. Please ensure that your comments are submitted within 
the specified comment period. Comments received after the close of the 
comment period will be marked ``late.'' EPA is not required to consider 
these late comments. Do not use EPA Dockets or e-mail to submit CBI or 
information protected by statute.
    1. Electronically. If you submit an electronic comment as 
prescribed in this unit, EPA recommends that you include your name, 
mailing address, and an e-mail address or other contact information in 
the body of your comment. Also include this contact information on the 
outside of any disk or CD ROM you submit, and in any cover letter 
accompanying the disk or CD ROM. This ensures that you can be 
identified as the submitter of the comment and allows EPA to contact 
you in case EPA cannot read your comment due to technical difficulties 
or needs further information on the substance of your comment. EPA's 
policy is that EPA will not edit your comment, and any identifying or 
contact information provided in the body of a comment will be included 
as part of the comment that is placed in the official public docket, 
and made available in EPA's electronic public docket. If EPA cannot 
read your comment due to technical difficulties and cannot contact you 
for clarification, EPA may not be able to consider your comment.
    i. EPA Dockets. Your use of EPA's electronic public docket to 
submit comments to EPA electronically is EPA's preferred method for 
receiving comments. Go directly to EPA Dockets at http://www.epa.gov/edocket/, and follow the online instructions for submitting comments. 
Once in the system, select ``search,'' and then key in docket ID number 
OPP-2005-0102. The system is an ``anonymous access'' system, which 
means EPA will not know your identity, e-mail address, or other contact 
information unless you provide it in the body of your comment.
    ii. E-mail. Comments may be sent by e-mail to [email protected], 
Attention: Docket ID Number OPP-2005-0102. In contrast to EPA's 
electronic public docket, EPA's e-mail system is not an ``anonymous 
access'' system. If you send an e-mail comment directly to the docket 
without going through EPA's electronic public docket, EPA's e-mail 
system automatically captures your e-mail address. E-mail addresses 
that are automatically captured by EPA's e-mail system are included as 
part of the comment that is placed in the official public docket, and 
made available in EPA's electronic public docket.
    iii. Disk or CD ROM. You may submit comments on a disk or CD ROM 
that you deliver as described in Unit I.C.2 or mail to the address 
provided in Unit I.C.3. These electronic submissions will be accepted 
in WordPerfect or ASCII file format. Avoid the use of special 
characters and any form of encryption.
    2. By hand delivery or courier. Deliver your comments to: Public 
Information and Records Integrity Branch (PIRIB), Office of Pesticide 
Programs (OPP), Environmental Protection Agency, Rm. 119, Crystal Mall 
2, 1801 South Bell St., Arlington, VA, Attention: Docket ID

[[Page 21748]]

Number OPP-2005-0102. Such deliveries are only accepted during the 
docket's normal hours of operation as identified in Unit I.B.1.

    3. By mail. Due to potential delays in EPA's receipt and processing 
of mail, respondents are strongly encouraged to submit comments either 
electronically or by hand delivery or courier. We cannot guarantee that 
comments sent via mail will be received prior to the close of the 
comment period. If mailed, please send your comments to: Public 
Information and Records Integrity Branch (PIRIB) (7502C), Office of 
Pesticide Programs (OPP), Environmental Protection Agency, 1200 
Pennsylvania Ave., NW., Washington, DC 20460-0001, Attention: Docket ID 
Number OPP-2005-0102.

Register citation.

E. How May I Participate in this Meeting?

    You may participate in this meeting by following the instructions 
in this unit. To ensure proper receipt by EPA, it is imperative that 
you identify docket ID number OPP-2005-0102 in the subject line on the 
first page of your request.
    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 DFO listed under FOR FURTHER INFORMATION 
CONTACT no later than noon, eastern time, June 7, 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 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, May 31, 2005, to 
provide FIFRA SAP the time necessary to consider and review the written 
comments. The DFO 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 DFO. 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 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: cholinesterase inhibition and 
recovery, pharmacokinetics/pharmocodynamics, statistics, exposure 
modeling. 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 
DFO listed under FOR FURTHER INFORMATION CONTACT on or before May 9, 
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 10 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 
Financial Disclosure, as supplemented by the 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 (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. The EPA will evaluate the candidate's

[[Page 21749]]

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

    Acute dietary exposure to pesticides is currently assessed using 
probabilistic models (DEEM-FCID, LifeLine, CARES) that combine the 
entire distributions of consumption and residue data. These models 
perform exposure assessments using total daily 24 hour consumption 
amounts. It is known, however, that the acute toxic effects of certain 
classes of chemicals are rapidly reversible. In the case of 
cholinesterase inhibition by carbamates, reversibility occurs within 
minutes to hours. Thus, the effect of exposure to carbamates should be 
assessed using consumption data that refer to single eating occasions, 
or shorter periods of time (less than 24 hours) to reflect the 
toxicology profiles of these compounds. The FIFRA Scientific Advisory 
Panel (February 1999) concurred with the validity of using the time-
dependent recovery of acetylcholinesterase to assess risks from 
repeated exposures to aldicarb.
    Recent advances in modeling have provided the capability to conduct 
exposure modeling in periods less than 24 hours. Two modules, designed 
for compatibility with the CARES model maintained by the International 
Life Sciences Institute, will be presented. The first module, referred 
to as the Dietary Minute Module (DMM) allocates daily consumption 
amount for an individual by minute of a day as recorded in the CSFII 
database. A user determined elapsed time interval is then applied that 
reflects the reversibility of cholinesterase activity for the carbamate 
of interest based on pharmacodynamic or toxicological studies. The time 
entered defines discrete eating occasions for an individual's day. Each 
discrete eating occasion ends when a period of consumption is followed 
by an elapsed time interval in which no consumption of carbamate 
residues has occurred. A distribution of exposure for all individuals' 
discrete eating occasions within a day for all days and individuals in 
the population of interest is then created. The second module, referred 
to as the Cholinesterase Activity Module (CAM), is a refinement of the 
DMM. It incorporates the time course for reversibility of exposure to 
an acetylcholinesterase inhibitor, rather than assuming a fixed elapsed 
time period. Time dependent changes in exposure are determined from 
corresponding changes in acetylcholinesterase activity. A more 
realistic estimate of exposure can then be calculated from a summation 
of residual activity from all eating events.

C. FIFRA SAP Meeting Minutes

     The FIFRA SAP will prepare meeting minutes summarizing its 
recommendations to the Agency in approximately 90 days after the 
meeting. The meeting minutes 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.
