III. Summary of Public Comments Received and Agency Response to Comments

On April 14, 2008, during the public comment period the registrant withdrew the voluntary cancellation of the grape use and submitted a PRIA action consisting of a change in the use of methomyl on grapes along with grape residue monitoring data provided by grape growers. While this new information refined the dietary assessment, it was not sufficient to change the Agency’s previous conclusion. As a result, the registrant withdrew the PRIA action on April 9, 2010. For this reason, the Agency does not believe that the information submitted during the comment period merits further review or a denial of the requests for voluntary use deletion.

IV. Cancellation Order

Pursuant to FIFRA section 6(f), EPA hereby approves the requested amendments to terminate uses of methomyl registrations identified in Table 1 of Unit II. Accordingly, the Agency hereby orders that the product registrations identified in Table 1 of Unit II. are amended to terminate the affected use. The effective date of the cancellations that are the subject of this notice is December 8, 2010. Any distribution, sale, or use of existing stocks of the products identified in Table 1 of Unit II. in a manner inconsistent with any of the provisions for disposition of existing stocks set forth in Unit VI. will be a violation of FIFRA. V. What is the Agency’s authority for taking this action?

Section 6(f)(1) of FIFRA provides that a registrant of a pesticide product may at any time request that any of its pesticide registrations be canceled or amended to terminate one or more uses. FIFRA further provides that, before acting on the request, EPA must publish a notice of receipt of any such request in the Federal Register . Thereafter, following the public comment period, the EPA Administrator may approve such a request. The notice of receipt for this action was published for comment on October 24, 2007 (72 FR 60634) (FRL–8153–3). The comment period closed on April 21, 2008. VI. Provisions for Disposition of Existing Stocks

Existing stocks are those stocks of registered pesticide products which are currently in the United States and which were packaged, labeled, and released for shipment prior to the effective date of the action. The existing stocks provision for the products subject to this order is as follows.

Now that EPA has approved product labels reflecting the requested amendments to delete uses, registrants are permitted to sell or distribute products listed in Table 1 of Unit II. under the previously approved labeling until June 8, 2012, a period of 18 months after publication of the cancellation order in this Federal Register , unless other restrictions have been imposed. Thereafter, registrants will be prohibited from selling or distributing the products whose labels include the deleted uses identified in Table 1 of Unit II., except for export consistent with FIFRA section 17 or for proper disposal.

Persons other than the registrant may sell, distribute, or use existing stocks of products whose labels include the deleted uses until supplies are exhausted, provided that such sale, distribution, or use is consistent with the terms of the previously approved labeling on, or that accompanied, products with the deleted uses.

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, 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 December 22, 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 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 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 Web site at http://epa.gov/scipoly/sap, or may be obtained from the OPP Regulatory Public Docket at http:// 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 the Food Quality Protection Act of 1996 (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 cancelled 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 uncertaintyfactors 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 2011. In 2008, the FIFRA Scientific Advisory Panel (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 merging this PBPK/PD model with CARES Cumulative and Aggregate Risk Evaluation System, see http:// www.ilsi.org/ResearchFoundation/ Pages/CARES.aspx, a publicallyavailable probabilistic exposure model. The purpose of the February 2011 SAP meeting will be to review the PBPK/PD model and to evaluate the proposed approach for linking this PBPK model to the probabilistic exposure model.

The linking of the chlorpyrifos PBPK/ PD model with a probabilistic exposure model may provide opportunities to calculate distributions of exposure to chlorpyrifos and its metabolites with cholinesterase inhibition levels across the U.S. population. In addition, this


### 76460 Federal Register / Vol. 75, No. 235 / Wednesday, December 8, 2010 / Notices

approach may allow estimation of dataderived 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 February 2011 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 with Stochastic Human Exposure and Dose Simulator (SHEDS) exposure software, a probabilistic exposure model developed by the EPA’s Office of Research and Development, which 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 February meeting is a key milestone in this research. The Agency will solicit feedback from the Panel on technical issues related to PBPK/PD model, the proposed approach for merging the PBPK/PD model with CARES, and the use of such merged models in risk assessment.
C. FIFRA SAP Documents and Meeting
