position, address, and telephone
number. Nominations should be
provided to the DFO listed under FOR
FURTHER INFORMATION CONTACT on or
before April 18, 2012. 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. 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 Web
site at https://www.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
recommendation to the Agency.

B. Public Meeting
In 2006, EPA initiated a program
called Registration Review to reevaluate all pesticides on a regular cycle
as part of the requirements of the FQPA.
The program reviews each pesticide
active ingredient every 15 years to make
sure that as the ability to assess risks to
human health and the environment
evolves and as policies and practices
change, all pesticide products in the
marketplace can still be used safely.
VerDate Mar<15>2010
15:28 Apr 03, 2012
Jkt 226001
EPA will soon be reviewing atrazine as
part of Registration Review.
An important step in the development
of a risk assessment is the problem
formulation. In a problem formulation,
available information, including stressor
sources and characteristics, exposure,
ecological effects on plants and animals
(e.g., amphibians, fish, invertebrates,
birds, and mammals), and
characteristics of the ecosystem(s), is
used to define assessment endpoints
and to develop a preliminary
understanding of potential risks (i.e.,
develop a risk hypothesis and
conceptual model) associated with the
use of a pesticide. The problem
formulation also serves as an
opportunity to identify missing
information/uncertainties that may limit
the assessment and any assumptions
that may be made in the absence of such
data. This SAP meeting will focus on
the proposed use of the Plant
Assemblage Toxicity Index (PATI)model, amphibians, and monitoring
data all which are components of the
problem formulation.
For the June 2012 SAP meeting, EPA
will provide an overview of the current
state of information on atrazine use,
environmental fate (exposure), and
ecological effects (toxicity) for assessing
the potential ecological risk from the
use of atrazine. Emphasis of the SAP
meeting will be directed at re-evaluation
of micro/mesocosm studies and their
impact on a PATI-derived level of
concern (LOC) for aquatic plant
communities and a strategy for using the
PATI-derived LOC for identification of
watersheds at risk. The strategy will
employ adjustments to control for bias
in atrazine concentrations from
monitoring data according to sampling
frequency. EPA will also include a
review of atrazine studies with
amphibians published in the open
literature since the 2007 SAP on
amphibians. This review will explore
whether additional effects have been
associated with exposure to atrazine and
whether there is a relationship between
effects reported across various studies
and common study design elements.
The SAP will be asked to comment on
whether the review is thorough and
whether uncertainties have been
sufficiently characterized.
The Interim Reregistration Eligibility
Decision (IRED) presented the results of
the atrazine ecological risk assessment
that identified the potential for
community and population risk to
sensitive aquatic species. Information in
the revised IRED was based in part on
the review and recommendations of the
SAP which met in June 2003 to discuss
the potential developmental effects of
PO 00000
Frm 00042
Fmt 4703
Sfmt 4703
atrazine on amphibians. At that
meeting, the Panel concurred with
EPA’s analysis that there was sufficient
evidence to formulate a hypothesis that
atrazine exposure may impact gonadal
development in amphibians, but there
were insufficient data at that time to
confirm or refute the hypothesis. This
led EPA to seek additional data through
a data call-in (DCI) to reduce
uncertainties regarding potential risk to
amphibians.
In October 2007, EPA convened a
second SAP meeting to evaluate
available data on atrazine effects on
gonadal development in amphibians.
The SAP reviewed the document
entitled ‘‘White Paper on the Potential
for Atrazine to Affect Amphibian
Gonadal Development’’ and concurred
with EPA that atrazine does not
consistently affect amphibian gonadal
development. Although the 2003 SAP
indicated that African clawed frog
(Xenopus laevis) was an appropriate test
species given the extent to which the
animal is used in amphibian
developmental studies, the 2007 Panel
concluded that a major uncertainty in
the registrant data was the use of X.
laevis as the test organism and the Panel
recommended that additional studies
were warranted on North American frog
species. The SAP acknowledged though
that there was uncertainty whether
study methods for North American
species were sufficiently developed or
vetted to yield consistent results.
Following the October 2007 SAP
meeting, EPA determined that it was
reasonable to reject the hypothesis that
atrazine exposure can affect gonadal
development. Consistent with the
recommendations from the 2003 SAP,
the Agency also determined, that given
the absence of consistent effects and
inability to reproduce effects used to
support the hypothesis that atrazine
affects amphibian development, there
was no compelling reason to pursue
additional testing with regard to the
potential effects of atrazine on
amphibian gonadal development.
However, the Agency acknowledged
that it would continue to monitor
research on this subject as it becomes
available.
Also as a condition of the 2003
reregistration, the atrazine registrants
were required to develop a monitoring
program to determine the extent to
which atrazine concentrations
associated with corn, sorghum, and
sugarcane production may be exceeding
levels that could cause effects to aquatic
plant communities. Forty watersheds
representing high atrazine use locations
vulnerable to atrazine runoff were
selected for monitoring using a
E:\FR\FM\04APN1.SGM
04APN1
emcdonald on DSK29S0YB1PROD with NOTICES
Federal Register / Vol. 77, No. 65 / Wednesday, April 4, 2012 / Notices
stratified, random statistical survey
design. Sampling within these
watersheds began in 2004 and is
ongoing in selected watersheds. There
are an additional 25 sites where
monitoring began in 2010 to refine the
approach for identifying vulnerable
watersheds. EPA is evaluating the
results of the atrazine monitoring
program, also in part, to identify the
characteristics of those watersheds that
resulted in atrazine exposures exceeding
the Agency’s LOC and to extrapolate
those results to other non-monitored
locations to determine where atrazine
concentrations may exceed the LOC.
In December 2007, EPA presented to
the SAP the use of the Comprehensive
Aquatic Systems Model (CASM) as a
tool to determine an LOC that relates
time variable monitoring data to effects
identified in a series of microcosm and
mesocosm studies. The SAP
recommended that EPA:
1. Work with the CASM–Atrazine
model to make the population time
series more realistic;
2. Provide a better validation of this
model, and
3. Conduct a more comprehensive
sensitivity analysis.
In May 2009, EPA presented a simpler
alternative to the CASM-based approach
to relate surface water monitoring data
to the microcosm and mesocosm data,
called the PATI. Other issues presented
at this meeting included a revised
assessment of the microcosm and
mesocosm exposure profiles, an update
on the ecological monitoring program
results, interpretation of the monitoring
results with PATI, 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 LOC. The
2009 Panel suggested that both the
CASM–Atrazine model (presented by
Syngenta) and PATI were suitable
assessment tools for atrazine. The PATI
model was recommended by the SAP as
a generic assessment tool for developing
an LOC, while CASM was
recommended by the SAP as a sitespecific assessment tool because of the
need for extensive site-specific data.
The Panel noted that a limitation in the
CASM model is the lack of
understanding of the sensitivity of
model predictions with correlations
among model parameters. The SAP
recommended that EPA re-evaluate the
meso/microcosm data set for study
quality and concentration-specific
effects, and provided additional
citations for meso/microcosm studies to
consider including in the assessment.
They also recommended using a
VerDate Mar<15>2010
15:28 Apr 03, 2012
Jkt 226001
probabilistic approach to determine the
LOC. The SAP concurred with EPA’s
incorporation of depth to impervious
layer and slope to identify vulnerable
watersheds for atrazine runoff as part of
the atrazine vulnerability index. They
also cautioned EPA that several
watershed factors such as atrazine use
intensity and rainfall are temporally
dependent and, therefore, should not be
considered minimum criteria in the
vulnerability index.

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 community ecology, surface water monitoring, water
quality, environmental fate and transport, aquatic toxicity, plant
toxicity, and statistics. 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 April 18, 2012. 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. 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
[[Page 20394]]
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 https://www.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
recommendation to the Agency.
B. Public Meeting
In 2006, EPA initiated a program called Registration Review to re-
evaluate all pesticides on a regular cycle as part of the requirements
of the FQPA. The program reviews each pesticide active ingredient every
15 years to make sure that as the ability to assess risks to human
health and the environment evolves and as policies and practices
change, all pesticide products in the marketplace can still be used
safely. EPA will soon be reviewing atrazine as part of Registration
Review.
An important step in the development of a risk assessment is the
problem formulation. In a problem formulation, available information,
including stressor sources and characteristics, exposure, ecological
effects on plants and animals (e.g., amphibians, fish, invertebrates,
birds, and mammals), and characteristics of the ecosystem(s), is used
to define assessment endpoints and to develop a preliminary
understanding of potential risks (i.e., develop a risk hypothesis and
conceptual model) associated with the use of a pesticide. The problem
formulation also serves as an opportunity to identify missing
information/uncertainties that may limit the assessment and any
assumptions that may be made in the absence of such data. This SAP
meeting will focus on the proposed use of the Plant Assemblage Toxicity
Index (PATI)-model, amphibians, and monitoring data all which are
components of the problem formulation.
For the June 2012 SAP meeting, EPA will provide an overview of the
current state of information on atrazine use, environmental fate
(exposure), and ecological effects (toxicity) for assessing the
potential ecological risk from the use of atrazine. Emphasis of the SAP
meeting will be directed at re-evaluation of micro/mesocosm studies and
their impact on a PATI-derived level of concern (LOC) for aquatic plant
communities and a strategy for using the PATI-derived LOC for
identification of watersheds at risk. The strategy will employ
adjustments to control for bias in atrazine concentrations from
monitoring data according to sampling frequency. EPA will also include
a review of atrazine studies with amphibians published in the open
literature since the 2007 SAP on amphibians. This review will explore
whether additional effects have been associated with exposure to
atrazine and whether there is a relationship between effects reported
across various studies and common study design elements. The SAP will
be asked to comment on whether the review is thorough and whether
uncertainties have been sufficiently characterized.
The Interim Reregistration Eligibility Decision (IRED) presented
the results of the atrazine ecological risk assessment that identified
the potential for community and population risk to sensitive aquatic
species. Information in the revised IRED was based in part on the
review and recommendations of the SAP which met in June 2003 to discuss
the potential developmental effects of atrazine on amphibians. At that
meeting, the Panel concurred with EPA's analysis that there was
sufficient evidence to formulate a hypothesis that atrazine exposure
may impact gonadal development in amphibians, but there were
insufficient data at that time to confirm or refute the hypothesis.
This led EPA to seek additional data through a data call-in (DCI) to
reduce uncertainties regarding potential risk to amphibians.
In October 2007, EPA convened a second SAP meeting to evaluate
available data on atrazine effects on gonadal development in
amphibians. The SAP reviewed the document entitled ``White Paper on the
Potential for Atrazine to Affect Amphibian Gonadal Development'' and
concurred with EPA that atrazine does not consistently affect amphibian
gonadal development. Although the 2003 SAP indicated that African
clawed frog (Xenopus laevis) was an appropriate test species given the
extent to which the animal is used in amphibian developmental studies,
the 2007 Panel concluded that a major uncertainty in the registrant
data was the use of X. laevis as the test organism and the Panel
recommended that additional studies were warranted on North American
frog species. The SAP acknowledged though that there was uncertainty
whether study methods for North American species were sufficiently
developed or vetted to yield consistent results. Following the October
2007 SAP meeting, EPA determined that it was reasonable to reject the
hypothesis that atrazine exposure can affect gonadal development.
Consistent with the recommendations from the 2003 SAP, the Agency also
determined, that given the absence of consistent effects and inability
to reproduce effects used to support the hypothesis that atrazine
affects amphibian development, there was no compelling reason to pursue
additional testing with regard to the potential effects of atrazine on
amphibian gonadal development. However, the Agency acknowledged that it
would continue to monitor research on this subject as it becomes
available.
Also as a condition of the 2003 reregistration, the atrazine
registrants were required to develop a monitoring program to determine
the extent to which atrazine concentrations associated with corn,
sorghum, and sugarcane production may be exceeding levels that could
cause effects to aquatic plant communities. Forty watersheds
representing high atrazine use locations vulnerable to atrazine runoff
were selected for monitoring using a
[[Page 20395]]
stratified, random statistical survey design. Sampling within these
watersheds began in 2004 and is ongoing in selected watersheds. There
are an additional 25 sites where monitoring began in 2010 to refine the
approach for identifying vulnerable watersheds. EPA is evaluating the
results of the atrazine monitoring program, also in part, to identify
the characteristics of those watersheds that resulted in atrazine
exposures exceeding the Agency's LOC and to extrapolate those results
to other non-monitored locations to determine where atrazine
concentrations may exceed the LOC.
In December 2007, EPA presented to the SAP the use of the
Comprehensive Aquatic Systems Model (CASM) as a tool to determine an
LOC that relates time variable monitoring data to effects identified in
a series of microcosm and mesocosm studies. The SAP recommended that
EPA:
1. Work with the CASM-Atrazine model to make the population time
series more realistic;
2. Provide a better validation of this model, and
3. Conduct a more comprehensive sensitivity analysis.
In May 2009, EPA presented a simpler alternative to the CASM-based
approach to relate surface water monitoring data to the microcosm and
mesocosm data, called the PATI. Other issues presented at this meeting
included a revised assessment of the microcosm and mesocosm exposure
profiles, an update on the ecological monitoring program results,
interpretation of the monitoring results with PATI, 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 LOC. The 2009 Panel suggested
that both the CASM-Atrazine model (presented by Syngenta) and PATI were
suitable assessment tools for atrazine. The PATI model was recommended
by the SAP as a generic assessment tool for developing an LOC, while
CASM was recommended by the SAP as a site-specific assessment tool
because of the need for extensive site-specific data. The Panel noted
that a limitation in the CASM model is the lack of understanding of the
sensitivity of model predictions with correlations among model
parameters. The SAP recommended that EPA re-evaluate the meso/microcosm
data set for study quality and concentration-specific effects, and
provided additional citations for meso/microcosm studies to consider
including in the assessment. They also recommended using a
probabilistic approach to determine the LOC. The SAP concurred with
EPA's incorporation of depth to impervious layer and slope to identify
vulnerable watersheds for atrazine runoff as part of the atrazine
vulnerability index. They also cautioned EPA that several watershed
factors such as atrazine use intensity and rainfall are temporally
dependent and, therefore, should not be considered minimum criteria in
the vulnerability index.
