[[Page 33302]]

    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, mammary gland 
development, mixtures study design and risk assessment, mode of action 
analysis (particularly those with mode of action (MOA) framework 
experience), frameworks to evaluate human relevance, pharmacokinetics, 
neuroendocrinology (hormone-mediated 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 June 25, 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 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 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 
recommendations to the Agency.

 B. Public Meeting

    EPA is undertaking a re-evaluation of the human health effects of 
atrazine. The re-evaluation involves three SAP meetings in 2010 and one 
in 2011. The first was held in February 2010 where 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 https://aghealth.nci.nih.gov/). The 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.
    2. Statistical approaches for evaluating monitoring frequency in 
community water systems (CWS).
    In 2011, the Agency will solicit comments from the SAP on atrazine 
cancer epidemiology studies. The Agency will consider the SAP feedback 
from the April meeting to help guide the preparation for the September 
meeting which will focus on the non-cancer effects of atrazine. The 
Agency will include studies available up through July 15, 2010. At this 
meeting OPP will integrate data from in vitro and in vivo experimental 
toxicology studies along with preliminary review of non-cancer 
epidemiology studies in a draft weight of the evidence (WOE) analysis. 
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. This draft 
framework employs the modified Bradford Hill Criteria, like that in the 
MOA and Human Relevance Frameworks, and the source to effects

[[Page 33303]]

paradigm described in the 2007 National Research Council Report, as 
tools to organize and review data from multiple sources and from 
multiple levels of biological organization. The Agency will develop a 
draft MOA analysis of the animal data describing key events for the 
hypothalamic-pituitary-adrenal and hypothalamic-pituitary-gonadal axes 
along with a description of temporal and dose-response concordance, and 
the strengths and remaining uncertainties in the data. The animal MOA 
will be integrated with epidemiology studies on atrazine into a draft 
WOE analysis.
    The Agency will also discuss alternative dose metrics for use in 
risk assessment and the strengths and limitations of each. The Agency 
will solicit feedback from the SAP on the implications of alternative 
dose metrics for performing dose response assessment in deriving points 
of departure, evaluating potential for differential lifestage 
susceptibility, and in determining the appropriate frequency of 
monitoring CWS.
    As a condition of reregistration of atrazine, EPA required the 
registrants to implement a monitoring program in selected CWS in the 
corn and sorghum growing area of the U.S. Midwest. Generally, longer 
durations of concern (e.g., annual average concentration for a long-
term chronic effect) require a less frequent sampling design to 
approximate longer term exposures. However, as the duration of the 
exposure of concern shortens, the frequency and timing of sampling 
become more important in determining how accurately the sample data 
capture these short-duration exposures. Depending on the aquatic 
resource being sampled, the likelihood increases that a spike in 
exposure may be missed by less frequent sampling. In light of the 
feedback received at the April SAP, the Agency will update proposed 
statistical approaches to determine the appropriate monitoring 
frequency for different toxicological durations of interest.
    The Agency will consider feedback received from the SAP at the 
September 2010 meeting as it completes the non-cancer WOE analysis 
integrating experimental toxicology and epidemiology studies with 
statistical analysis for determining whether or not adjustments are 
necessary in the sampling frequency of CWS water monitoring.

C. FIFRA SAP Documents and Meeting Minutes

    EPA's background paper, related supporting materials, charge/
questions to FIFRA SAP, FIFRA SAP composition (i.e., members and ad hoc 
members for this meeting), and the meeting agenda will be available by 
mid-August. In addition, the Agency may provide additional background 
documents as the materials become available. You may obtain electronic 
copies of these documents, and certain other related documents that 
might be available electronically, at https://www.regulations.gov and 
the FIFRA SAP homepage at https://www.epa.gov/scipoly/sap.
    FIFRA SAP will prepare meeting minutes summarizing its 
recommendations to the Agency approximately 90 days after the meeting. 
The meeting minutes will be posted on the FIFRA SAP website or may be 
obtained from the OPP Regulatory Public Docket at https://www.regulations.gov.
