Environmental justice. EPA seeks to achieve environmental justice, the fair treatment and meaningful involvement of any group, including minority and/or low-income populations, in the development, implementation, and enforcement of environmental laws, regulations, and policies. To help address potential environmental justice issues, the Agency seeks information on any groups or segments of the population who, as a result of their location, cultural practices, or other factors, may have atypical or disproportionately high and adverse human health impacts or environmental effects from exposure to the pesticides discussed in this document, compared to the general population. jlentini on DSKJ8SOYB1PROD with NOTICES II. What Action is the Agency Taking? EPA is announcing its receipt of several pesticide petitions filed under section 408 of the Federal Food, Drug, and Cosmetic Act (FFDCA), 21 U.S.C. 346a, proposing the establishment or modification of regulations in 40 CFR part 174 or part 180 for residues of pesticide chemicals in or on various food commodities. EPA has determined that the pesticide petitions described in this notice contain the data or information prescribed in FFDCA section 408(d)(2); however, EPA has not fully evaluated the sufficiency of the submitted data at this time or whether the data support granting of the pesticide petitions. Additional data may be needed before EPA can make a final determination on these pesticide petitions. Pursuant to 40 CFR 180.7(f), a summary of each of the petitions that are the subject of this notice, prepared by the petitioner, is included in a docket EPA has created for each rulemaking. The docket for each of the petitions is available on-line at https:// www.regulations.gov. As specified in FFDCA section 408(d)(3), (21 U.S.C. 346a(d)(3)), EPA is publishing notice of the petition so that the public has an opportunity to comment on this request for the establishment or modification of regulations for residues of pesticides in or on food commodities. Further information on the petition may be obtained through the petition summary referenced in this unit. VerDate Nov<24>2008 16:53 Aug 18, 2009 Jkt 217001 New Tolerance Exemption 1. PP 9E7557.

II. What Action is the Agency Taking?

     EPAs Office of Prevention, Pesticides and Toxic Substances (OPPTS) 
provided notice on October 31, 1995 (60 FR 55376) (FRL-4987-3) of the 
establishment of the NAC/AEGL Committee with the stated charter 
objective as ``the efficient and effective development of AEGLs and the 
preparation of supplementary qualitative information on the hazardous 
substances for Federal, State, and Local agencies and organizations in 
the private sector concerned with [chemical] emergency planning, 
prevention, and response.'' The NAC/AEGL Committee is a discretionary 
Federal advisory committee formed with the intent to develop AEGLs for 
hazardous substances through the combined efforts of stakeholder 
members from both the public and private sectors in a cost-effective 
approach that avoids duplication of efforts and provides uniform 
values, while employing the most scientifically sound methods 
available.
    This action provides notice of availability for public review and 
comment, of proposed AEGLs and underlying supporting documents for 19 
hazardous substances. These AEGLs represent the 12\th\ set of exposure 
levels proposed and published by the NAC/AEGL Committee. These 12 sets 
of AEGLs cover 259 hazardous substances. Background information on the 
AEGL Program may be found in these earlier Federal Register notices, in 
the regulations.gov, or on the AEGL

[[Page 41898]]

webpage (https://www.epa.gov/oppt/aegl).
    Following public review and comment, the NAC/AEGL Committee will 
reconvene to consider relevant comments, data, and information that may 
have an impact on the NAC/AEGL Committees position and will again seek 
consensus for the establishment of Interim AEGLs. Although the Interim 
AEGLs will be available to Federal, State and local agencies and to 
organizations in the private sector as biological reference values, it 
is intended to have them reviewed by a subcommittee of the National 
Academies (NAS). The NAS subcommittee will serve as a peer review of 
the Interim AEGLs and as the final arbiter in the resolution of issues 
regarding the AEGLs, and the data and basic methodology used for 
setting AEGLs. Following concurrence, Final AEGLs will be published 
under the auspices of the NAS.

III. List of Hazardous Substances

    On behalf of the NAC/AEGL Committee, EPA is providing an 
opportunity for public comment on the proposed AEGLs for the 19 
hazardous substances identified in the table in this unit. Technical 
Support Documents are available in the docket for this notice. See 
ADDRESSES for docket information.
