VerDate Mar<15>2010 18:40 Aug 17, 2010 Jkt 220001 1. Written comments. The Agency encourages that written comments be submitted, using the instructions in ADDRESSES, no later than September 27, 2010, to provide FIFRA SAP the time necessary to consider and review the written comments. Written comments are accepted until the date of the meeting, but anyone submitting written comments after September 27, 2010, should contact the DFO listed under FOR FURTHER INFORMATION CONTACT. Anyone submitting written comments at the meeting should bring 30 copies for distribution to FIFRA SAP. 2. Oral comments. The Agency encourages that each individual or group wishing to make brief oral comments to FIFRA SAP submit their request to the DFO listed under FOR FURTHER INFORMATION CONTACT no later than September 30, 2010, in order to be included on the meeting agenda. Requests to present oral comments will be accepted until the date of the meeting and, to the extent that time permits, the Chair of FIFRA SAP may permit the presentation of oral comments at the meeting by interested persons who have not previously requested time. 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 25 copies of his or her comments and presentation slides for distribution to the FIFRA SAP at the meeting. 3. Seating at the meeting. Seating at the meeting will be open and on a firstcome basis. 4. Request for nominations to serve as ad hoc members of FIFRA SAP for this meeting. As part of a broader process for developing a pool of candidates for each meeting, FIFRA SAP staff routinely solicits the stakeholder community for nominations of prospective candidates for service as ad hoc members of 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: Risk Assessment, organophosphate pesticides, cholinesterase inhibition, data derived uncertainty factors (also referred to as chemical specific adjustment factors), pharmacodynamic modeling, physiologically based pharmacokinetic modeling, biomonitoring data, statistical modeling, PO 00000 Frm 00060 Fmt 4703 Sfmt 4703 probabilistic techniques, and dietary exposure to pesticides. 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 August 30, 2010. 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 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. Although 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 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 10-15 ad hoc scientists. FIFRA SAP members are subject to the provisions of 5 CFR part 2634, Executive Branch Financial Disclosure, as supplemented by the EPA in 5 CFR part 6401. In anticipation of this requirement, prospective candidates for service on the FIFRA SAP will be asked to submit confidential financial information which shall fully disclose among other financial interests, the candidate’s employment, stocks and E:\FR\FM\18AUN1.SGM 18AUN1 Federal Register / Vol. 75, No. 159 / Wednesday, August 18, 2010 / Notices bonds, and where applicable, sources of research support. EPA will evaluate the candidates financial disclosure form to assess whether there are financial conflicts of interest, appearance of a lack of impartiality or any prior involvement with the development of the documents under consideration (including previous scientific peer review) before the candidate is considered further for service on 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 website at https://epa.gov/scipoly/sap or may be obtained from the OPP Regulatory Public Docket at https:// www.regulations.gov. sroberts on DSKD5P82C1PROD with NOTICES II. Background A. Purpose of FIFRA SAP FIFRA SAP serves as the primary scientific peer review mechanism of EPA’s Office of Chemical Safety and Pollution Prevention (OCSPP) and is structured to provide scientific advice, information and recommendations to the EPA Administrator on pesticides and pesticide-related issues as to the impact of regulatory actions on health and the environment. FIFRA SAP is a Federal advisory committee established in 1975 under FIFRA that operates in accordance with requirements of the Federal Advisory Committee Act. FIFRA SAP is composed of a permanent panel consisting of seven members who are appointed by the EPA Administrator from nominees provided by the National Institutes of Health and the National Science Foundation. FIFRA, as amended by FQPA, established a Science Review Board consisting of at least 60 scientists who are available to the SAP on an ad hoc basis to assist in reviews conducted by the SAP. As a peer review mechanism, FIFRA SAP provides comments, evaluations and recommendations to improve the effectiveness and quality of analyses made by Agency scientists. Members of FIFRA SAP are scientists who have sufficient professional qualifications, including training and experience, to provide expert advice and recommendation to the Agency. B. Public Meeting Chlorpyrifos (0,0-diethyl-0-3,5,6trichloro-2-pyridyl phosphorothioate) is a broad-spectrum, chlorinated VerDate Mar<15>2010 18:40 Aug 17, 2010 Jkt 220001 organophosphate (OP) insecticide. In 2000, nearly all residential uses were voluntarily canceled by Dow AgroSciences, but agricultural uses remain. The 2000 human health risk assessment was largely based on adult laboratory animal data (rat or dog) for cholinesterase inhibition and the application of default uncertainty factors to address inter- and intraspecies differences including susceptible populations. Currently, the Agency is developing a new human health risk assessment expected to be released in 2010. In 2008, the FIFRA SAP reviewed a draft science issue paper on the human health effects of chlorpyrifos. Since that time, Dow AgroSciences has undergone a research effort to improve the existing physiologically based pharmacokinetic/ pharmacodynamic model (PBPK/PD) developed by Dr. Charles Timchalk and co-workers at Pacific Northwest National Laboratory. Dow AgroSciences has also developed a proposed approach for linking this PBPK/PD model to the Cumulative and Aggregate Risk Evaluation System (CARES), see https:// www.ilsi.org/ResearchFoundation/ Pages/ CARES.aspx, a publically available probabilistic exposure model. The purpose of the October 2010 SAP meeting will be to review the PBPK/PD model and to evaluate the proposed approach for linking this model to CARES. The linking of the chlorpyrifos PBPK/ PD model to CARES may provide opportunities to integrate distributions of exposure to chlorpyrifos and its metabolites with cholinesterase inhibition levels across the U.S. population. In addition, this approach may allow estimation of data-derived uncertainty factors that consider use of toxicokinetic and toxicodynamic data to inform quantitative extrapolations for interspecies differences and human variability in dose response assessment. The topics to be covered in the October 2010 SAP are consistent with EPA’s Office of Pesticide Programs continuing efforts to improve the scientific basis for risk assessment by broadening the application of probabilistic exposure techniques and PBPK models. The Agency has a conceptually similar effort on-going to link PBPK models for pyrethroids to the Stochastic Human Exposure and Dose Simulation model for multimedia and multipathway chemicals (SHEDS-Multimedia), a probabilistic exposure model developed by EPA’s Office of Research and Development, that was reviewed by the SAP in July 2010. The current effort by Dow AgroSciences is a research effort PO 00000 Frm 00061 Fmt 4703 Sfmt 4703 51043 which may, if sufficiently robust, inform future risk assessments. The October meeting is a key milestone in this effort. The Agency will solicit feedback from the Panel on technical issues related to the PBPK/PD model, the proposed approach for linking the PBPK/PD model with CARES, and the use of such linked models in risk assessment.

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 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. Although 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 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 10-15 ad hoc scientists.
    FIFRA SAP members are subject to the provisions of 5 CFR part 2634, 
Executive Branch Financial Disclosure, as supplemented by the EPA in 5 
CFR part 6401. In anticipation of this requirement, prospective 
candidates for service on the FIFRA SAP will be asked to submit 
confidential financial information which shall fully disclose among 
other financial interests, the candidate's employment, stocks and

[[Page 51043]]

bonds, and where applicable, sources of research support. EPA will 
evaluate the candidates financial disclosure form to assess whether 
there are financial conflicts of interest, appearance of a lack of 
impartiality or any prior involvement with the development of the 
documents under consideration (including previous scientific peer 
review) before the candidate is considered further for service on 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 website at https://epa.gov/scipoly/sap 
or may be obtained from the OPP Regulatory Public Docket at https://www.regulations.gov.

 II. Background

 A. Purpose of FIFRA SAP

    FIFRA SAP serves as the primary scientific peer review mechanism of 
EPA's Office of Chemical Safety and Pollution Prevention (OCSPP) and is 
structured to provide scientific advice, information and 
recommendations to the EPA Administrator on pesticides and pesticide-
related issues as to the impact of regulatory actions on health and the 
environment. FIFRA SAP is a Federal advisory committee established in 
1975 under FIFRA that operates in accordance with requirements of the 
Federal Advisory Committee Act. FIFRA SAP is composed of a permanent 
panel consisting of seven members who are appointed by the EPA 
Administrator from nominees provided by the National Institutes of 
Health and the National Science Foundation. FIFRA, as amended by FQPA, 
established a Science Review Board consisting of at least 60 scientists 
who are available to the SAP on an ad hoc basis to assist in reviews 
conducted by the SAP. As a peer review mechanism, FIFRA SAP provides 
comments, evaluations and recommendations to improve the effectiveness 
and quality of analyses made by Agency scientists. Members of FIFRA SAP 
are scientists who have sufficient professional qualifications, 
including training and experience, to provide expert advice and 
recommendation to the Agency.

 B. Public Meeting

    Chlorpyrifos (0,0-diethyl-0-3,5,6-trichloro-2-pyridyl 
phosphorothioate) is a broad-spectrum, chlorinated organophosphate (OP) 
insecticide. In 2000, nearly all residential uses were voluntarily 
canceled by Dow AgroSciences, but agricultural uses remain. The 2000 
human health risk assessment was largely based on adult laboratory 
animal data (rat or dog) for cholinesterase inhibition and the 
application of default uncertainty factors to address inter- and intra-
species differences including susceptible populations. Currently, the 
Agency is developing a new human health risk assessment expected to be 
released in 2010. In 2008, the FIFRA SAP reviewed a draft science issue 
paper on the human health effects of chlorpyrifos. Since that time, Dow 
AgroSciences has undergone a research effort to improve the existing 
physiologically based pharmacokinetic/pharmacodynamic model (PBPK/PD) 
developed by Dr. Charles Timchalk and co-workers at Pacific Northwest 
National Laboratory. Dow AgroSciences has also developed a proposed 
approach for linking this PBPK/PD model to the Cumulative and Aggregate 
Risk Evaluation System (CARES), see https://www.ilsi.org/ResearchFoundation/Pages/ CARES.aspx, a publically available 
probabilistic exposure model. The purpose of the October 2010 SAP 
meeting will be to review the PBPK/PD model and to evaluate the 
proposed approach for linking this model to CARES.
    The linking of the chlorpyrifos PBPK/PD model to CARES may provide 
opportunities to integrate distributions of exposure to chlorpyrifos 
and its metabolites with cholinesterase inhibition levels across the 
U.S. population. In addition, this approach may allow estimation of 
data-derived uncertainty factors that consider use of toxicokinetic and 
toxicodynamic data to inform quantitative extrapolations for 
interspecies differences and human variability in dose response 
assessment. The topics to be covered in the October 2010 SAP are 
consistent with EPA's Office of Pesticide Programs continuing efforts 
to improve the scientific basis for risk assessment by broadening the 
application of probabilistic exposure techniques and PBPK models. The 
Agency has a conceptually similar effort on-going to link PBPK models 
for pyrethroids to the Stochastic Human Exposure and Dose Simulation 
model for multimedia and multipathway chemicals (SHEDS-Multimedia), a 
probabilistic exposure model developed by EPA's Office of Research and 
Development, that was reviewed by the SAP in July 2010. The current 
effort by Dow AgroSciences is a research effort which may, if 
sufficiently robust, inform future risk assessments. The October 
meeting is a key milestone in this effort. The Agency will solicit 
feedback from the Panel on technical issues related to the PBPK/PD 
model, the proposed approach for linking the PBPK/PD model with CARES, 
and the use of such linked models in risk assessment.
