Background lotter on DSK11XQN23PROD with NOTICES1 A. What is the purpose of the FIFRA SAP? The FIFRA SAP serves as one of the primary scientific peer review mechanisms of EPA’s Office of Chemical Safety and Pollution Prevention (OCSPP) and is structured to provide independent scientific advice, information, and recommendations to the EPA Administrator on pesticides and pesticide-related issues as to the impact of regulatory actions on human health and the environment. 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 VerDate Sep<11>2014 17:10 Jun 30, 2023 Jkt 259001 Institutes of Health and the National Science Foundation. FIFRA established a Science Review Board consisting of at least 60 scientists who are available to the FIFRA SAP on an ad hoc basis to assist in reviews conducted by the FIFRA SAP. As a scientific 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 recommendations to the Agency. B. Why did EPA develop this document? EPA participated in several FIFRA SAP meetings related to atrazine’s impact on the environment (e.g., 2003, 2007, 2009, 2012). In June 2012, the EPA presented the ‘‘Problem Formulation for the Environmental Fate and Ecological Risk Assessment for Atrazine’’ to the FIFRA SAP. That problem formulation provided an overview of atrazine use, exposure, and toxicity for assessing the ecological risk from atrazine use. One of the major considerations for the 2012 FIFRA SAP was the process that the EPA used to estimate an aquatic plant communitybased concentration equivalent-level of concern (CE–LOC). The CE–LOC is a 60day average concentration of atrazine that, when exceeded, presents a greater than 50 percent chance of negatively affecting the productivity, structure, and/or function of an aquatic plant community. Cosm studies examining the toxicity of atrazine to aquatic plant communities are a significant part of the process to estimate the CE–LOC. Accordingly, from 2002 to 2016, the EPA considered over 70 cosm studies obtained from the open literature or submitted to the EPA. The 2012 FIFRA SAP identified 11 specific cosm studies from that dataset (Table 1, page 42–43 of the meeting report) as warranting further review (in terms of their inclusion/exclusion in the analysis or the effect/no effect determinations for specific measured endpoints) because of concerns about study design or performance flaws, as well as the interpretation of results. In response to the 2012 FIFRA SAP, the EPA re-evaluated the 11 specific cosm studies identified by the FIFRA SAP and presented this re-evaluation in the 2013 ‘‘Addendum to the Problem Formulation for the Ecological Risk Assessment to be Conducted for the Registration Review of Atrazine’’ and the 2016 ‘‘Refined Ecological Risk Assessment for Atrazine.’’ In conducting PO 00000 Frm 00040 Fmt 4703 Sfmt 4703 42717 this 2013 and 2016 re-evaluation, EPA considered comments from the 2012 FIFRA SAP and the public. This reevaluation did not result in a change in the Agency’s understanding or interpretation of those 11 studies. After the issuance of the 2016 ecological risk assessment and the 2022 ‘‘Proposed Revisions to the Atrazine Interim Registration Review Decision,’’ the EPA received additional public comments about the 11 studies, including a reminder that the Agency had stated in 2016 its intent to convene a FIFRA SAP meeting, along with renewed requests to convene a FIFRA SAP meeting, regarding the studies. The EPA is returning to the FIFRA SAP to seek feedback on the outcome of the EPA’s 2023 evaluation regarding the inclusion of the 11 studies, and if appropriate, effect/no effect determinations for specific measured endpoints from the studies that were identified by the 2012 FIFRA SAP. III. Virtual Public Meeting of the FIFRA SAP A. How can I access the documents submitted for review to the FIFRA SAP? These documents, including the reevaluation document mentioned above and all background documents, related supporting materials, and draft charge questions provided to the FIFRA SAP are available in the docket at https://www.regulations.gov (docket ID No. EPA–HQ–OPP–2023–0154) and the FIFRA SAP website at https:// www.epa.gov/sap. In addition, as additional background materials become available and are provided to the FIFRA SAP, EPA will include those additional background documents (e.g., FIFRA SAP members and consultants participating in the meeting and the meeting agenda) in the docket and accessible through the FIFRA SAP website. After the public meeting, the FIFRA SAP will prepare meeting minutes and a final report document summarizing its recommendations to the EPA. This document will also be posted on in the docket and available at regulations.gov and the FIFRA SAP website. B. How can I provide comments for the FIFRA SAP’s consideration?

SUPPLEMENTARY INFORMATION:

I. General Information

A. What action is the Agency taking?

    EPA is announcing the availability of and soliciting public comment 
on the document entitled ``Examination of Microcosm/Mesocosm Studies 
for Evaluating the Effects of Atrazine on Aquatic Plant Communities,'' 
which is available in the docket. EPA is also announcing a 3-day 
virtual public meeting on August 22-24, 2023, for the FIFRA SAP to 
consider and review the Agency's examination. This August 2023 meeting 
was previously announced in the Federal Register of March 24, 2023 (88 
FR 17843 (FRL-10803-01-OCSPP)). EPA will be soliciting comments from 
the FIFRA SAP on the Agency's examination related to 11 microcosm and 
mesocosm studies evaluating the toxicity of atrazine to the exposed 
aquatic plant communities.
    This document provides instructions for accessing the materials 
provided to the FIFRA SAP, submitting written comments, and registering 
to provide oral comments and attend the virtual meeting.

B. What is the Agency's authority for taking this action?

    The FIFRA SAP is a federal advisory committee established in 1975 
under FIFRA, 7 U.S.C. 136 et seq., to provide independent scientific 
advice to EPA on health and safety issues related to pesticides. The 
FIFRA SAP operates in accordance with the Federal Advisory Committee 
Act (FACA), 5 U.S.C. 10, and

[[Page 42717]]

supports activities under FIFRA, the Federal Food, Drug, and Cosmetic 
Act (FFDCA) and other applicable statutes.

C. Does this action apply to me?

    This action is directed to the public in general. This action may 
be of interest to persons who are or may be required to conduct testing 
of chemical substances under the FFDCA and FIFRA. Since other entities 
may also be interested, the Agency has not attempted to describe all 
the specific entities that may be affected by this action.

II. Background

A. What is the purpose of the FIFRA SAP?

    The FIFRA SAP serves as one of the primary scientific peer review 
mechanisms of EPA's Office of Chemical Safety and Pollution Prevention 
(OCSPP) and is structured to provide independent scientific advice, 
information, and recommendations to the EPA Administrator on pesticides 
and pesticide-related issues as to the impact of regulatory actions on 
human health and the environment. 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 established a Science 
Review Board consisting of at least 60 scientists who are available to 
the FIFRA SAP on an ad hoc basis to assist in reviews conducted by the 
FIFRA SAP. As a scientific 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 recommendations to the Agency.

B. Why did EPA develop this document?

    EPA participated in several FIFRA SAP meetings related to 
atrazine's impact on the environment (e.g., 2003, 2007, 2009, 2012). In 
June 2012, the EPA presented the ``Problem Formulation for the 
Environmental Fate and Ecological Risk Assessment for Atrazine'' to the 
FIFRA SAP. That problem formulation provided an overview of atrazine 
use, exposure, and toxicity for assessing the ecological risk from 
atrazine use. One of the major considerations for the 2012 FIFRA SAP 
was the process that the EPA used to estimate an aquatic plant 
community-based concentration equivalent-level of concern (CE-LOC). The 
CE-LOC is a 60-day average concentration of atrazine that, when 
exceeded, presents a greater than 50 percent chance of negatively 
affecting the productivity, structure, and/or function of an aquatic 
plant community.
    Cosm studies examining the toxicity of atrazine to aquatic plant 
communities are a significant part of the process to estimate the CE-
LOC. Accordingly, from 2002 to 2016, the EPA considered over 70 cosm 
studies obtained from the open literature or submitted to the EPA. The 
2012 FIFRA SAP identified 11 specific cosm studies from that dataset 
(Table 1, page 42-43 of the meeting report) as warranting further 
review (in terms of their inclusion/exclusion in the analysis or the 
effect/no effect determinations for specific measured endpoints) 
because of concerns about study design or performance flaws, as well as 
the interpretation of results.
    In response to the 2012 FIFRA SAP, the EPA re-evaluated the 11 
specific cosm studies identified by the FIFRA SAP and presented this 
re-evaluation in the 2013 ``Addendum to the Problem Formulation for the 
Ecological Risk Assessment to be Conducted for the Registration Review 
of Atrazine'' and the 2016 ``Refined Ecological Risk Assessment for 
Atrazine.'' In conducting this 2013 and 2016 re-evaluation, EPA 
considered comments from the 2012 FIFRA SAP and the public. This re-
evaluation did not result in a change in the Agency's understanding or 
interpretation of those 11 studies. After the issuance of the 2016 
ecological risk assessment and the 2022 ``Proposed Revisions to the 
Atrazine Interim Registration Review Decision,'' the EPA received 
additional public comments about the 11 studies, including a reminder 
that the Agency had stated in 2016 its intent to convene a FIFRA SAP 
meeting, along with renewed requests to convene a FIFRA SAP meeting, 
regarding the studies.
    The EPA is returning to the FIFRA SAP to seek feedback on the 
outcome of the EPA's 2023 evaluation regarding the inclusion of the 11 
studies, and if appropriate, effect/no effect determinations for 
specific measured endpoints from the studies that were identified by
