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 May 8, 2009, 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 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: Aquatic ecology, aquatic community modeling, environmental sampling statistics, environmental monitoring design and exposure assessment, watershed vulnerability assessment, including experience in evaluating chemical run-off potential, and soil science. 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 March 6, 2009. 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 10-12 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. 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 http://www.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 Prevention, Pesticides and Toxic Substances (OPPTS) 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

The Interim Risk Assessment Eligibility Document (IRED) for atrazine in 2003 presented the results of an ecological risk assessment that identified the potential for community and population risk to sensitive aquatic species. As a condition of reregistration, the atrazine registrants were required to develop a monitoring program to determine the extent to which atrazine concentrations associated with corn and sorghum production may be exceeding levels that could cause effects to aquatic communities. Forty watersheds out of a potential 1,172 representing high atrazine use locations most vulnerable to atrazine runoff were selected for monitoring using a stratified, random statistical survey design. Sampling within these watersheds began in 2004 and is ongoing in selected watersheds. The Agency intends to evaluate the results of the atrazine monitoring study in order to identify the characteristics of those watersheds that resulted in atrazine exposures that exceeded the Agency's level of concern (LOC) and to extrapolate those results to other non-monitored locations to determine where other exceedences of the LOC may occur.

In December 2007, the Agency presented to the SAP the use of the Comprehensive Aquatic Systems Model (CASM) as a tool to determine a LOC that relates time variable monitoring data to effects identified in a series of microcosm and mesocosm studies which were used in the original atrazine (IRED) assessment. In addition, the Agency presented an approach on how to identify other potential sites outside of the 40 that were monitored based on similar use, watershed vulnerability and other factors. The SAP recommended that the Agency make the population time series more realistic in the CASM_Atrazine model, provide a better validation of this model, and perform a more comprehensive sensitivity analysis. In May 2009, the Agency will present evaluations of the applicability of a revised CASM_Atrazine model to freshwater atrazine risk assessments and reasons for deciding not to proceed with further development and application of this model. A simpler alternative to the CASM-based approach will be presented for relating surface water monitoring data to the microcosm and mesocosm data. Other issues presented will include a revised assessment of the microcosm and mesocosm exposure profiles, an update on the monitoring program results, interpretation of the surface water monitoring results with both the revised CASM and the alternative approach, identification of the watershed factors driving atrazine runoff, and extrapolation of those results to the entire atrazine use area to identify other areas where atrazine exposures may exceed the levels of concern. Finally, EPA's Office of Water is examining statistical alternatives for expressing the model results as a numeric criterion applicable to potentially sparse data sets typical of what is often available for water bodies.
