In addition, each speaker should bring 30 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 first-come 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, environmental epidemiology, exposure assessment (particularly pesticide applicators), mammary gland development, mode of action analysis (particularly those with MOA framework experience), frameworks to evaluate human relevance, prostate development, pharmacokinetics, physiologically-based pharmacokinetic modeling, neuroendocrinology, hormone-mediated health effects, HPA axis (corticosterone), reproductive/developmental biology and environmental sampling and statistical 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 20, 2011. 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 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 bonds, and where applicable, sources of research support. The EPA will evaluate the candidate's financial disclosure Start Printed Page 26289form 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 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

EPA is undertaking a re-evaluation of the human health effects of atrazine. The human health re-evaluation has involved three SAP meetings in 2010 and one in 2011. The first meeting was held in February 2010 during which the Agency presented its preliminary reviews of several atrazine epidemiology studies on birth outcomes and described a project plan to evaluate atrazine epidemiology data from the Agricultural Health Study (http://aghealth.nci.nih.gov/​). The second meeting in April 2010 SAP meeting focused on:

1. A preliminary review of experimental toxicology studies from laboratory mammals and in vitro studies and recent advancements in understanding atrazine's mode of action along with;

2. Statistical and modeling approaches for evaluating monitoring frequency in community water systems (CWS). The September 2010 meeting built on the scientific analysis and SAP feedback from the April meeting. Specifically, the Agency presented scientific analyses on an empirical approach for estimating internal dosimetry, and calculation of benchmark dose estimates for purposes of deriving points of departure. In addition, EPA presented a general strategy for designing a monitoring study to characterize drinking water exposures and discussed different methods for analyzing and interpreting monitoring data collected at different sampling frequencies. The September 2010 meeting also provided proposals for updating the critical durations of exposure based on the new science, and a preliminary evaluation of potential susceptibility of the young. In addition, the September 2010 meeting included evaluation of non-cancer epidemiology studies, a weight of the evidence evaluation of the non-cancer epidemiology studies with experimental laboratory studies, and a proposal to use the non-cancer epidemiology studies qualitatively in evaluating the human relevance of experimental toxicology findings.

The July 2011 SAP meeting will build on the scientific analyses and SAP feedback from the previous three SAP meetings by proposing a conceptual framework for the evaluation of atrazine human health non-cancer effects. This proposed conceptual framework will integrate information on mode of action and adverse outcome pathways, potentially susceptible lifestages/subpopulations, drinking water exposure, internal dosimetry, and water monitoring sampling uncertainty. The Agency will solicit comment on the overall integrative approach proposed for atrazine along with technical considerations for each scientific component. To illustrate the conceptual framework, a case study will be provided that demonstrates an approach for estimating non-cancer risk to atrazine based on an internal dose metric for temporally, spatially, and demographically explicit information. The Agency will use feedback received from the SAP at the July 2011 meeting as it completes the scientific analysis for determining whether or not adjustments may be necessary in the sampling frequency of CWS monitoring. The evaluation of non-cancer effects will include studies available up through April 29, 2010.

In the 2003 Interim Reregistration Eligibility Decision (IRED) for atrazine, the Agency noted that it would convene another SAP meeting concerning atrazine and its possible association with carcinogenic effects, particularly as new information from the National Cancer Institute's (NCI) Agricultural Health Study (AHS) is made available. The Agency believes it is appropriate at this time to re-evaluate the cancer epidemiology literature on atrazine in a SAP meeting; EPA notes that the evidence of atrazine carcinogenicity based upon experimental animal data were evaluated by the SAP in April 2010. As such, at the July 2011 meeting, the Agency will provide a preliminary review of cancer epidemiology studies and a draft weight of the evidence (WOE) analysis on cancer that integrates mode of action, experimental toxicology information, and epidemiology. This draft WOE analysis will follow the Draft Framework for Incorporating Epidemiologic and Human Incident Data in Health Risk Assessment, which was reviewed by the SAP in February 2010. The Agency will include epidemiological studies on the cancer effects of atrazine available up through April 29, 2010. The Agricultural Health Study is anticipated to be published in spring 2011 and will be part of this review given that this study is considered to be a pivotal line of evidence.

At the February 2010 SAP, the Agency presented a proposed plan for a collaborative project with investigators from the AHS to evaluate approaches for estimating exposure to pesticide applicators. At the July 2011 meeting, the Agency will discuss the status of the collaborative project (which includes a case study involving atrazine) and solicit comment from the Panel on the overall direction of the project and the methods development aspects of this effort. This project is part of a larger effort by OPP to improve the incorporation of epidemiology in human health risk assessment. The feedback from the SAP may not be used for atrazine risk assessment per se but Start Printed Page 26290will inform EPA's continued efforts to improve risk assessment approaches and methodologies.
