[[Page 53571]]

Chair of the 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 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 
solicits 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: 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 October 3, 2007. 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. 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 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. 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 
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 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 website 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 the FIFRA SAP

    The 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. The FIFRA SAP is a Federal advisory 
committee established in 1975 under FIFRA that operates in accordance 
with requirements of the Federal Advisory Committee Act. The 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 
Scientific Advisory Panel on an ad hoc basis to assist in reviews 
conducted by the Scientific Advisory Panel. As a peer review mechanism, 
the FIFRA SAP provides comments, evaluations and recommendations to 
improve the effectiveness and quality of analyses made by Agency 
scientists. Members of the 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

    A risk assessment was conducted by EPA as part of the 2003 Interim 
Registration Eligibility Document (IRED) for the pesticide active 
ingredient atrazine. The assessment indicated potential community-and 
population-level risk to sensitive aquatic ecosystems at prolonged 
concentrations of atrazine from 10 - 20 parts per billion. As a 
condition of re-registration, atrazine registrants were required to 
develop a monitoring program to determine the extent to which atrazine 
concentrations in streams associated with corn and sorghum production 
may be exceeding levels that could cause effects to aquatic 
communities. If the threshold were exceeded, then a watershed-based 
mitigation program could be required.
    The atrazine exposure threshold was developed based on an analysis 
of the magnitude and duration of atrazine exposure that caused 
significant effects as reported in experimental microcosm and mesocosm 
studies. The primary endpoint of concern focused on impacts

[[Page 53572]]

to the primary producers in the aquatic plant community and the 
subsequent impacts to community structure. The monitoring program 
design was based on a population of 1,172 watersheds whose streams were 
identified as highly vulnerable to atrazine exposure based on factors 
such as atrazine use intensity in corn and sorghum production and run-
off vulnerability. A sub-set of 40 sites was selected for monitoring 
using a stratified, random statistical survey design. Streams were 
monitored for a minimum of two years with samples collected at least 
once every four days. Data from each stream were evaluated on a yearly 
basis to determine if atrazine concentrations were detected at 
sufficient levels over sufficiently long time durations to exceed the 
exposure threshold of concern. Based on the sampling design, the 
results from the streams in the 40 watersheds allow statistically-based 
inferences to the larger population of 1,172 watersheds vulnerable to 
atrazine runoff.
    Key questions to be addressed by the FIFRA SAP at this public 
meeting are as follows:
    1. Based on available experimental microcosm and mesocosm studies 
and ecosystem response models were the relationships between atrazine 
exposure profiles and aquatic community responses determined in a 
reasonable and transparent manner to establish thresholds of concern 
for atrazine?
    2. Based on the monitoring design, is the approach to estimating 
the extent of watersheds in corn and sorghum producing areas that 
exceed atrazine thresholds of concern for aquatic community effects 
appropriate?
    3. Based on results of the monitoring study, are the hypotheses and 
related methods and data sets being employed to identify potential 
watershed attributes associated with higher atrazine exposures 
appropriate?

C. FIFRA SAP Documents and Meeting Minutes

    EPA's background paper, related supporting materials, charge/
questions to the FIFRA SAP, FIFRA SAP composition (i.e., members and ad 
hoc members for this meeting), and the meeting agenda will be available
