3. 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.

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, requesting 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. The Agency is taking public comment on the requests before responding to the petitioners. EPA is not proposing any particular action at this time. EPA has determined that the pesticide petitions described in this document 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. After considering the public comments, EPA intends to evaluate whether and what action may be warranted. 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 document, prepared by the petitioner, is included in a docket EPA has created for each rulemaking. The docket for each of the petitions is available online at http://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.

New Tolerance Exemptions

1. PP 2E7990. (EPA-HQ-OPP-2012-0287). Arristec, Inc., 135 Old River Road, Milford, NJ 08848 requests to establish an exemption from the requirement of a tolerance for residues of Diisopropyl Naphthalene (DIPN) (CAS No. 38640-62-9) when used as a pesticide inert ingredient in pesticide formulations under 40 CFR 180.910 pre- and post-harvest, and 40 CFR 180.930 Animal Uses. Diisopropyl Naphthalene (DIPN) (CAS No. 38640-62-9) is already approved as a pesticide inert ingredient for non-food uses. The petitioner believes no analytical method is needed because it is not required for the establishment of a tolerance exemption for inert ingredients. Contact: Lisa Austin, (703) 305-7894, email address: austin.lisa@epa.gov.

2. PP 2E7995. (EPA-HQ-OPP-2012-0278). Stepan Company, 22 West Frontage Road, Northfield, IL 60093, requests to establish an exemption from the requirement of a tolerance for fatty acids, tall-oil, ethoxylated propoxylated (CAS No. 67784-86-5; 2009 amu) when used as a pesticide inert ingredient as a surfactant without limitations in pesticide formulations under CFR 180.960 in or on all raw agricultural commodities. Stepan Company is petitioning that fatty acids, tall-oil, ethoxylated propoxylated (CAS No.: 67784-86-5; 2009 amu) be exempt from the requirement of a tolerance based upon the definition of a low-risk polymer under 40 CFR 723.250. Therefore, an analytical method to determine residues on treated crops is not relevant. Contact: William Cutchin, (703) 305-7990, email address: cutchin.william@epa.gov.

3. PP 2E8000. (EPA-HQ-OPP-2012-0279). Stepan Company, 22 West Frontage Road, Northfield, IL 60093, requests to establish an exemption from the requirement of a tolerance for residues of α-(ρ-Nonylphenyl)poly(oxypropylene) block polymer with poly(oxyethylene) (CAS No. 37251-69-7; Mn = 1889 Daltons) when used as a pesticide inert ingredient as a surfactant in pesticide formulations under CFR 180.960 in or on all raw agricultural commodities without limitations. Stepan Company is petitioning that α-(p -Nonylphenyl)poly(oxypropylene) block polymer with poly(oxyethylene) (CAS# 37251-69-7; Mn=1889 Daltons) be exempt from the requirement of a tolerance based upon the definition of a low-risk polymer under 40 CFR 723.250. Therefore, an analytical method to determine residues on treated crops is not relevant. Contact: William Cutchin, (703) 305-7990, email address: cutchin.william@epa.gov.

4. PP 2F8014. (EPA-HQ-OPP-2012-0389). Vestaron Corporation, 4717 Campus Drive, Suite 1200, Kalamazoo, MI 49008, requests to establish an exemption from the requirement of a tolerance for residues of the insecticide GS-U-ACTX-Hvla-SEQ2, in or on ornamental plants, turf and edible crops. The petitioner believes no analytical method is needed because it is expected that, when used as proposed, GS-U-ACTX-Hvla-SEQ2, would not result in residues that are of toxicological concern.
