Summary of Petitioned-For Tolerance In the Federal Register of July 6, 2011 (76 FR 39358) (FRL–8875–6) and of July 20, 2011 (76 FR 43233) (FRL–8880–1), EPA issued documents pursuant to FFDCA section 408(d)(3), 21 U.S.C. 346a(d)(3), announcing the filing of pesticide petitions (PP 1F7841) by Valent U.S.A. Corporation, 1600 Riviera Ave., Suite 200, Walnut Creek, CA 94596 and PP 1E7850 by IR–4, 500 College Road East, Suite 201W, Princeton, NJ 08540. The petitions requested that 40 CFR part 180 be amended by establishing tolerances for residues of the fungicide fenpyrazamine, S-allyl 5-amino-2isopropyl-4-(2-methylphenyl)-3-oxo-2,3dihydropyrazole-1-carbothioate, in or on: Almond at 0.02 parts per million (ppm); almond, hulls at 1.5 ppm; lettuce, head at 2.5 ppm; lettuce, leaf at 2.5 ppm; small fruit vine climbing subgroup, except fuzzy kiwi fruit, crop subgroup 13–07F at 3.5 ppm; grape, juice at 7.0 ppm; grape, raisins at 4.5 ppm; low growing berry subgroup 13– 07G at 3.0 ppm (PP 1F7841); pistachio at 0.02 ppm; Caneberry subgroup 13– 07A at 7.0 ppm; Bushberry subgroup 13–07B at 7.0 ppm; and ginseng at 0.80 ppm (PP 1E7850). Those documents referenced a summary of the petitions prepared by Valent U.S.A. Corporation, the registrant, which are available in the docket, https://www.regulations.gov. There were no comments received in response to the notices of filing. Based upon review of the data supporting the petition, EPA has determined that the tolerances should be based upon parent fenpyrazamine only, has revised the tolerance levels for several commodities, and determined a tolerance is not needed for raisins. The reason for these changes is explained in Unit IV.D. E:\FR\FM\06MRR1.SGM 06MRR1 14462 Federal Register / Vol. 78, No. 44 / Wednesday, March 6, 2013 / Rules and Regulations pmangrum on DSK3VPTVN1PROD with RULES III. Aggregate Risk Assessment and Determination of Safety Section 408(b)(2)(A)(i) of FFDCA allows EPA to establish a tolerance (the legal limit for a pesticide chemical residue in or on a food) only if EPA determines that the tolerance is ‘‘safe.’’ Section 408(b)(2)(A)(ii) of FFDCA defines ‘‘safe’’ to mean that ‘‘there is a reasonable certainty that no harm will result from aggregate exposure to the pesticide chemical residue, including all anticipated dietary exposures and all other exposures for which there is reliable information.’’ This includes exposure through drinking water and in residential settings, but does not include occupational exposure. Section 408(b)(2)(C) of FFDCA requires EPA to give special consideration to exposure of infants and children to the pesticide chemical residue in establishing a tolerance and to ‘‘ensure that there is a reasonable certainty that no harm will result to infants and children from aggregate exposure to the pesticide chemical residue * * * .’’ Consistent with FFDCA section 408(b)(2)(D), and the factors specified in FFDCA section 408(b)(2)(D), EPA has reviewed the available scientific data and other relevant information in support of this action. EPA has sufficient data to assess the hazards of and to make a determination on aggregate exposure for fenpyrazamine including exposure resulting from the tolerances established by this action. EPA’s assessment of exposures and risks associated with fenpyrazamine follows. A. Toxicological Profile EPA has evaluated the available toxicity data and considered its validity, completeness, and reliability as well as the relationship of the results of the studies to human risk. EPA has also considered available information concerning the variability of the sensitivities of major identifiable subgroups of consumers, including infants and children. The principal toxicological findings for fenpyrazamine in repeated dose studies in rodents, rabbits, and dogs were reduced bodyweights/bodyweight weight gains. In addition, thyroid follicular cell hypertrophy was observed in rats in the subchronic, chronic/ carcinogenicity and reproduction toxicity (parental animals only) studies. Although increased liver weights, hepatocellular hypertrophy, and alterations in hematology and clinical chemistry parameters were observed in several studies, they were not considered to be toxicologically relevant since the magnitude of the changes was VerDate Mar<15>2010 13:26 Mar 05, 2013 Jkt 229001 within normal variability. The liver alterations were therefore considered adaptive rather than adverse effects. There was no evidence of increased susceptibility of developing organisms after in utero or post-natal exposure to fenpyrazamine in the developmental toxicity studies (rats and rabbits) or the multi-generation reproduction toxicity study. In both the rat and rabbit developmental studies, maternal effects (decreased body weight) occurred at doses lower than or equal to those eliciting developmental effects (decreased fetal weight, skeletal variations in rats and late abortions and premature deliveries in rabbits). Since the late abortions and premature deliveries occurred at doses higher than the maternal LOAEL, this finding is not considered to be indicative of susceptibility. In the multi-generation reproduction toxicity study, thyroid toxicity was observed in parental animals at the same dose eliciting decreased body weights in the offspring. Reproductive effects manifested as decreases in implantations and increases in postimplantation loss occurred at a dose level approximately 4x higher than the parental and offspring LOAELs. The only potential sign of neurotoxicity was a decrease in total motor activity and total number of rearings observed in the acute neurotoxicity study in rats. However, given that the liver is the target tissue, these effects may be nonspecific effects secondary to general toxicity. These effects were not observed in the subchronic neurotoxicity or any other studies in the database. In a 28-day dermal toxicity study, no hazard was identified at the limit dose 1,000 milligrams/kilogram/day (mg/kg/ day). Similarly, an immunotoxicity study in rats did not indicate that the immune system is a target for fenpyrazamine toxicity. Although an increase in the incidence of hepatocellular and thyroid follicular carcinomas was noted in the chronic/ carcinogenicity study in rats, the concern for these findings is low based on the following weight of evidence considerations: 1. The marginal increases occurred only at the high dose; 2. There was no reduction in the latency period (i.e., tumors were seen only at the terminal sacrifice); and 3. The incidences were only slightly outside the historical control range of the testing laboratories. In addition, no neoplastic lesions attributable to treatment were observed in the carcinogenicity study in mice and PO 00000 Frm 00026 Fmt 4700 Sfmt 4700 no indication of mutagenicity was noted in the mutagenicity battery. Based on this evidence, in accordance with the Agency’s 2005 Guidelines for Cancer Risk Assessment, EPA classified fenpyrazamine as ‘‘Not Likely to be Carcinogenic to Humans’’. Specific information on the studies received and the nature of the adverse effects caused by fenpyrazamine as well as the no-observed-adverse-effect-level (NOAEL) and the lowest-observedadverse-effect-level (LOAEL) from the toxicity studies can be found at https:// www.regulations.gov in section 4.5.4 in the document ‘‘Human Health Risk Assessment for the Section 3 Registration and Establishment of Tolerances on Almond, Small Fruit Climbing Subgroup 13–07F, Head and Leaf Lettuce, and Low Growing Berry Subgroup 13–07G, Bushberry Subgroup 13–07B, Caneberry Subgroup 13–07A, Ginseng, and Pistachio’’ in docket ID number EPA–HQ–OPP–2011–0357. B. Toxicological Points of Departure/ Levels of Concern Once a pesticide’s toxicological profile is determined, EPA identifies toxicological points of departure (POD) and levels of concern to use in evaluating the risk posed by human exposure to the pesticide. For hazards that have a threshold below which there is no appreciable risk, the toxicological POD is used as the basis for derivation of reference values for risk assessment. PODs are developed based on a careful analysis of the doses in each toxicological study to determine the dose at which no adverse effects are observed (the NOAEL) and the lowest dose at which adverse effects of concern are identified (the LOAEL). Uncertainty/ safety factors are used in conjunction with the POD to calculate a safe exposure level—generally referred to as a population-adjusted dose (PAD) or a reference dose (RfD)—and a safe margin of exposure (MOE). For non-threshold risks, the Agency assumes that any amount of exposure will lead to some degree of risk. Thus, the Agency estimates risk in terms of the probability of an occurrence of the adverse effect expected in a lifetime. For more information on the general principles EPA uses in risk characterization and a complete description of the risk assessment process, see https:// www.epa.gov/pesticides/factsheets/ riskassess.htm. A summary of the toxicological endpoints for fenpyrazamine used for human risk assessment is shown in the following Table.

In evaluating dietary exposure to fenpyrazamine, EPA considered exposure under the petitioned-for tolerances in 40 CFR 180. EPA assessed dietary exposures from fenpyrazamine in food as follows: i. Acute exposure. Quantitative acute dietary exposure and risk assessments are performed for a food-use pesticide, if a toxicological study has indicated the possibility of an effect of concern occurring as a result of a 1-day or single exposure. Such effects were identified for fenpyrazamine. In estimating acute dietary exposure, EPA used food consumption information from the 2003 to 2008 United States Department of Agriculture (USDA) National Health and Nutrition Examination Survey, What We Eat in America, (NHANES/WWEIA). For residue levels in food, EPA assumed 100 percent crop treated (PCT) and tolerance level residues of parent fenpyrazamine plus the maximum residue of S–2188– DC (expressed as parent fenpyrazamine) observed in the crop field trials for the proposed uses. ii. Chronic exposure. In conducting the chronic dietary exposure assessment EPA used the food consumption data from the 2003 to 2008 United States Department of Agriculture (USDA) National Health and Nutrition Examination Survey, What We Eat in America, (NHANES/WWEIA). For residue levels in food, EPA assumed 100 PCT and tolerance level residues of parent fenpyrazamine plus the maximum residue of S–2188–DC (expressed as parent fenpyrazamine) observed in the crop field trials for the proposed uses. iii. Cancer. Based on the data summarized in Unit III.A., EPA has concluded that fenpyrazamine does not pose a cancer risk to humans. Therefore, VerDate Mar<15>2010 13:26 Mar 05, 2013 Jkt 229001 a dietary exposure assessment for the purpose of assessing cancer risk is unnecessary. iv. Anticipated residue and PCT information. EPA did not use anticipated residue or PCT information in the dietary assessment for fenpyrazamine. Tolerance level residues and 100 PCT were assumed for all food commodities. 2. Dietary exposure from drinking water. The Agency used screening level water exposure models in the dietary exposure analysis and risk assessment for fenpyrazamine in drinking water. These simulation models take into account data on the physical, chemical, and fate/transport characteristics of fenpyrazamine. Further information regarding EPA drinking water models used in pesticide exposure assessment can be found at https://www.epa.gov/ oppefed1/models/water/index.htm. Based on the Tier 1 FQPA Index Reservoir Screening Tool (FIRST v. 1.1.1, released March 26, 2008) for surface water and the Screening Concentration in Ground Water (SCI– GROW) model for ground water, the estimated drinking water concentrations (EDWCs) of fenpyrazamine for acute exposures are estimated to be 213.5 parts per billion (ppb) for surface water and 1.31 ppb for ground water. The chronic exposures are estimated to be 72.5 ppb for surface water and 1.31 ppb for ground water. Modeled estimates of drinking water concentrations were directly entered into the dietary exposure model. For acute dietary risk assessment, the water concentration value of 213.5 ppb was used to assess the contribution to drinking water. For chronic dietary risk assessment, the water concentration of value 72.5 ppb was used to assess the contribution to drinking water. 3. From non-dietary exposure. The term ‘‘residential exposure’’ is used in PO 00000 Frm 00027 Fmt 4700 Sfmt 4700 this document to refer to nonoccupational, non-dietary exposure (e.g., for lawn and garden pest control, indoor pest control, termiticides, and flea and tick control on pets). Fenpyrazamine is not registered for any specific use patterns that would result in residential exposure. 4. Cumulative effects from substances with a common mechanism of toxicity. Section 408(b)(2)(D)(v) of FFDCA requires that, when considering whether to establish, modify, or revoke a tolerance, the Agency consider ‘‘available information’’ concerning the cumulative effects of a particular pesticide’s residues and ‘‘other substances that have a common mechanism of toxicity.’’ EPA has not found fenpyrazamine to share a common mechanism of toxicity with any other substances, and fenpyrazamine does not appear to produce a toxic metabolite produced by other substances. For the purposes of this tolerance action, therefore, EPA has assumed that fenpyrazamine does not have a common mechanism of toxicity with other substances. For information regarding EPA’s efforts to determine which chemicals have a common mechanism of toxicity and to evaluate the cumulative effects of such chemicals, see EPA’s Web site at https:// www.epa.gov/pesticides/cumulative. D. Safety Factor for Infants and Children 1. In general. Section 408(b)(2)(C) of FFDCA provides that EPA shall apply an additional tenfold (10X) margin of safety for infants and children in the case of threshold effects to account for prenatal and postnatal toxicity and the completeness of the database on toxicity and exposure unless EPA determines based on reliable data that a different margin of safety will be safe for infants E:\FR\FM\06MRR1.SGM 06MRR1 14464 Federal Register / Vol. 78, No. 44 / Wednesday, March 6, 2013 / Rules and Regulations pmangrum on DSK3VPTVN1PROD with RULES and children. This additional margin of safety is commonly referred to as the FQPA Safety Factor (SF). In applying this provision, EPA either retains the default value of 10X, or uses a different additional safety factor when reliable data available to EPA support the choice of a different factor. 2. Prenatal and postnatal sensitivity. There is no evidence of increased preand/or postnatal susceptibility based on the results of the rat and rabbit prenatal developmental toxicity studies, and the rat 2-generation reproductive toxicity study. 3. Conclusion. EPA has determined that reliable data show the safety of infants and children would be adequately protected if the FQPA SF were reduced to 1x. That decision is based on the following findings: i. The toxicity database for fenpyrazamine is complete. ii. There is no evidence of increased pre- and/or postnatal susceptibility for fenpyrazamine. iii. There is no residual uncertainty in the exposure database for fenpyrazamine with respect to dietary (food and water) exposure. The dietary food exposure assessments were performed based on 100 PCT and tolerance-level residues of parent fenpyrazamine plus the maximum reside of the metabolite S–2188–DC, empirical concentration factors and default processing factors. EPA made conservative (protective) assumptions in the ground and surface water modeling used to assess exposure to fenpyrazamine in drinking water. These assessments will not underestimate the exposure and risks posed by fenpyrazamine. E. Aggregate Risks and Determination of Safety EPA determines whether acute and chronic dietary pesticide exposures are safe by comparing aggregate exposure estimates to the aPAD and chronic population-adjusted dose (cPAD). For linear cancer risks, EPA calculates the lifetime probability of acquiring cancer given the estimated aggregate exposure. Short-term, intermediate-term, and chronic-term risks are evaluated by comparing the estimated aggregate food, water, and residential exposure to the appropriate PODs to ensure that an adequate MOE exists. Since there are no residential uses proposed for fenpyrazamine, the aggregate risks are equal to the dietary and drinking water assessments. 1. Acute risk. Using the exposure assumptions discussed in this unit for acute exposure, the acute dietary exposure from food and water to VerDate Mar<15>2010 13:26 Mar 05, 2013 Jkt 229001 fenpyrazamine will occupy 9.2% of the aPAD for children 1–2 years old, the population group receiving the greatest exposure. 2. Chronic risk. Using the exposure assumptions described in this unit for chronic exposure, EPA has concluded that chronic exposure to fenpyrazamine from food and water will utilize 7.3% of the cPAD for children 1–2 years old, the population group receiving the greatest exposure. 3. Short-term and intermediate-term risk. Short-term and intermediate-term aggregate exposure takes into account short-term or intermediate-term residential exposure plus chronic exposure to food and water (considered to be a background exposure level). Fenpyrazamine is not registered for any use patterns that would result in shortterm or intermediate-term residential exposure. Short-term and intermediateterm risk is assessed based on shortterm or intermediate-term residential exposure plus chronic dietary exposure. Because there is no short-term or intermediate-term residential exposure and chronic dietary exposure has already been assessed under the appropriately protective cPAD (which is at least as protective as the POD used to assess short-term risk), no further assessment of short-term or intermediate-term risk is necessary, and EPA relies on the chronic dietary risk assessment for evaluating short-term and intermediate-term risk for fenpyrazamine. 4. Aggregate cancer risk for U.S. population. Based on the results of two adequate rodent carcinogenicity studies, fenpyrazamine is not expected to pose a cancer risk to humans. 5. Determination of safety. Based on these risk assessments, EPA concludes that there is a reasonable certainty that no harm will result to the general population, or to infants and children from aggregate exposure to fenpyrazamine residues. IV. Other Considerations A. Analytical Enforcement Methodology Parent fenpyrazamine only is the residue of concern for tolerance enforcement purposes. Valent U.S.A. Corporation has submitted the results of an independent laboratory validation (ILV) by liquid chromatography and mass spectrometry (LC/MS/MS), Method RM–45C–1, titled ‘‘Determination of S–2188 and S–2188– DC in crops’’. The method is considered adequate for enforcement of tolerances in plant commodities. The method may be requested from: Chief, Analytical Chemistry Branch, PO 00000 Frm 00028 Fmt 4700 Sfmt 4700 Environmental Science Center, 701 Mapes Rd., Ft. Meade, MD 20755–5350; telephone number: (410) 305–2905; email address: residuemethods@epa.gov. B. International Residue Limits In making its tolerance decisions, EPA seeks to harmonize U.S. tolerances with international standards whenever possible, consistent with U.S. food safety standards and agricultural practices. EPA considers the international maximum residue limits (MRLs) established by the Codex Alimentarius Commission (Codex), as required by FFDCA section 408(b)(4). The Codex Alimentarius is a joint United Nations Food and Agriculture Organization/World Health Organization food standards program, and it is recognized as an international food safety standards-setting organization in trade agreements to which the United States is a party. EPA may establish a tolerance that is different from a Codex MRL; however, FFDCA section 408(b)(4) requires that EPA explain the reasons for departing from the Codex level. Fenpyrazamine is a new active ingredient and MRLs have not been established by Codex, Canada, or Mexico for the commodities proposed for registration in the US. C. Revisions to Petitioned-For Tolerances The Agency established parent fenpyrazamine only as the residue of concern for tolerance enforcement in plants and tolerances were recommended accordingly. These differ from the tolerances proposed by the registrant, which are based on residues of parent fenpyrazamine and the metabolite S–2188–DC expressed as fenpyrazamine. In addition, the Organization for the Economical Cooperation and Development (OECD) calculation procedures were used to estimate the tolerances and based on these procedures, the Agency has determined that the lettuce, head tolerance should be lowered from 2.0 to 1.5 ppm; lettuce, leaf from 2.5 ppm to 2 ppm; Caneberry subgroup 13–07A from 7.0 ppm to 5 ppm; Bushberry subgroup 13–07B from 7.0 ppm to 5 ppm; small fruit vine climbing subgroup except fuzzy kiwi fruit, subgroup 13– 07F from 3.5 ppm to 3 ppm; and grape, juice from 7.0 ppm to 4 ppm. Finally, the submitted grape processing data indicate that residues of parent fenpyrazamine only concentrate in raisins at 1.1x. Therefore, the concentration factor for raisin is not E:\FR\FM\06MRR1.SGM 06MRR1 14465 Federal Register / Vol. 78, No. 44 / Wednesday, March 6, 2013 / Rules and Regulations high enough to justify the need of a separate tolerance for raisins. pmangrum on DSK3VPTVN1PROD with RULES V. Conclusion Therefore, tolerances are established for residues of fenpyrazamine, S-allyl 5amino-2-isopropyl-4-(2-methylphenyl)3-oxo-2,3-dihydropyrazole-1carbothioate, in or on Almond at 0.02 ppm; almond, hulls at 1.5 ppm; pistachio at 0.02 ppm; lettuce, head at 1.5 ppm; lettuce, leaf at 2 ppm; Caneberry subgroup 13–07A at 5 ppm; Bushberry subgroup 13–07B at 5 ppm; small fruit vine climbing subgroup except fuzzy kiwi fruit, subgroup 13– 07F at 3 ppm; grape, juice at 4 ppm; low growing berry subgroup 13–07G at 3 ppm; and ginseng at 0.7 ppm. VI. Statutory and Executive Order Reviews This final rule establishes tolerances under FFDCA section 408(d) in response to a petition submitted to the Agency. The Office of Management and Budget (OMB) has exempted these types of actions from review under Executive Order 12866, entitled ‘‘Regulatory Planning and Review’’ (58 FR 51735, October 4, 1993). Because this final rule has been exempted from review under Executive Order 12866, this final rule is not subject to Executive Order 13211, entitled ‘‘Actions Concerning Regulations That Significantly Affect Energy Supply, Distribution, or Use’’ (66 FR 28355, May 22, 2001) or Executive Order 13045, entitled ‘‘Protection of Children from Environmental Health Risks and Safety Risks’’ (62 FR 19885, April 23, 1997). This final rule does not contain any information collections subject to OMB approval under the Paperwork Reduction Act (PRA) (44 U.S.C. 3501 et seq.), nor does it require any special considerations under Executive Order 12898, entitled ‘‘Federal Actions to Address Environmental Justice in Minority Populations and Low-Income Populations’’ (59 FR 7629, February 16, 1994). Since tolerances and exemptions that are established on the basis of a petition under FFDCA section 408(d), such as the tolerance in this final rule, do not require the issuance of a proposed rule, the requirements of the Regulatory Flexibility Act (RFA) (5 U.S.C. 601 et seq.), do not apply. This final rule directly regulates growers, food processors, food handlers, and food retailers, not States or tribes, nor does this action alter the relationships or distribution of power and responsibilities established by Congress in the preemption provisions of FFDCA section 408(n)(4). As such, VerDate Mar<15>2010 13:26 Mar 05, 2013 Jkt 229001 the Agency has determined that this action will not have a substantial direct effect on States or tribal governments, on the relationship between the national government and the States or tribal governments, or on the distribution of power and responsibilities among the various levels of government or between the Federal Government and Indian tribes. Thus, the Agency has determined that Executive Order 13132, entitled ‘‘Federalism’’ (64 FR 43255, August 10, 1999) and Executive Order 13175, entitled ‘‘Consultation and Coordination with Indian Tribal Governments’’ (65 FR 67249, November 9, 2000) do not apply to this final rule. In addition, this final rule does not impose any enforceable duty or contain any unfunded mandate as described under Title II of the Unfunded Mandates Reform Act of 1995 (UMRA) (2 U.S.C. 1501 et seq.).

II. Summary of Petitioned-For Tolerance

    In the Federal Register of July 6, 2011 (76 FR 39358) (FRL-8875-6) 
and of July 20, 2011 (76 FR 43233) (FRL-8880-1), EPA issued documents 
pursuant to FFDCA section 408(d)(3), 21 U.S.C. 346a(d)(3), announcing 
the filing of pesticide petitions (PP 1F7841) by Valent U.S.A. 
Corporation, 1600 Riviera Ave., Suite 200, Walnut Creek, CA 94596 and 
PP 1E7850 by IR-4, 500 College Road East, Suite 201W, Princeton, NJ 
08540. The petitions requested that 40 CFR part 180 be amended by 
establishing tolerances for residues of the fungicide fenpyrazamine, S-
allyl 5-amino-2-isopropyl-4-(2-methylphenyl)-3-oxo-2,3-dihydropyrazole-
1-carbothioate, in or on: Almond at 0.02 parts per million (ppm); 
almond, hulls at 1.5 ppm; lettuce, head at 2.5 ppm; lettuce, leaf at 
2.5 ppm; small fruit vine climbing subgroup, except fuzzy kiwi fruit, 
crop subgroup 13-07F at 3.5 ppm; grape, juice at 7.0 ppm; grape, 
raisins at 4.5 ppm; low growing berry subgroup 13-07G at 3.0 ppm (PP 
1F7841); pistachio at 0.02 ppm; Caneberry subgroup 13-07A at 7.0 ppm; 
Bushberry subgroup 13-07B at 7.0 ppm; and ginseng at 0.80 ppm (PP 
1E7850). Those documents referenced a summary of the petitions prepared 
by Valent U.S.A. Corporation, the registrant, which are available in 
the docket, https://www.regulations.gov. There were no comments received 
in response to the notices of filing.
    Based upon review of the data supporting the petition, EPA has 
determined that the tolerances should be based upon parent 
fenpyrazamine only, has revised the tolerance levels for several 
commodities, and determined a tolerance is not needed for raisins. The 
reason for these changes is explained in Unit IV.D.

[[Page 14462]]

III. Aggregate Risk Assessment and Determination of Safety

    Section 408(b)(2)(A)(i) of FFDCA allows EPA to establish a 
tolerance (the legal limit for a pesticide chemical residue in or on a 
food) only if EPA determines that the tolerance is ``safe.'' Section 
408(b)(2)(A)(ii) of FFDCA defines ``safe'' to mean that ``there is a 
reasonable certainty that no harm will result from aggregate exposure 
to the pesticide chemical residue, including all anticipated dietary 
exposures and all other exposures for which there is reliable 
information.'' This includes exposure through drinking water and in 
residential settings, but does not include occupational exposure. 
Section 408(b)(2)(C) of FFDCA requires EPA to give special 
consideration to exposure of infants and children to the pesticide 
chemical residue in establishing a tolerance and to ``ensure that there 
is a reasonable certainty that no harm will result to infants and 
children from aggregate exposure to the pesticide chemical residue * * 
* .'' Consistent with FFDCA section 408(b)(2)(D), and the factors 
specified in FFDCA section 408(b)(2)(D), EPA has reviewed the available 
scientific data and other relevant information in support of this 
action. EPA has sufficient data to assess the hazards of and to make a 
determination on aggregate exposure for fenpyrazamine including 
exposure resulting from the tolerances established by this action. 
EPA's assessment of exposures and risks associated with fenpyrazamine 
follows.

A. Toxicological Profile

    EPA has evaluated the available toxicity data and considered its 
validity, completeness, and reliability as well as the relationship of 
the results of the studies to human risk. EPA has also considered 
available information concerning the variability of the sensitivities 
of major identifiable subgroups of consumers, including infants and 
children.
    The principal toxicological findings for fenpyrazamine in repeated 
dose studies in rodents, rabbits, and dogs were reduced bodyweights/
bodyweight weight gains. In addition, thyroid follicular cell 
hypertrophy was observed in rats in the subchronic, chronic/
carcinogenicity and reproduction toxicity (parental animals only) 
studies. Although increased liver weights, hepatocellular hypertrophy, 
and alterations in hematology and clinical chemistry parameters were 
observed in several studies, they were not considered to be 
toxicologically relevant since the magnitude of the changes was within 
normal variability. The liver alterations were therefore considered 
adaptive rather than adverse effects.
    There was no evidence of increased susceptibility of developing 
organisms after in utero or post-natal exposure to fenpyrazamine in the 
developmental toxicity studies (rats and rabbits) or the multi-
generation reproduction toxicity study. In both the rat and rabbit 
developmental studies, maternal effects (decreased body weight) 
occurred at doses lower than or equal to those eliciting developmental 
effects (decreased fetal weight, skeletal variations in rats and late 
abortions and premature deliveries in rabbits). Since the late 
abortions and premature deliveries occurred at doses higher than the 
maternal LOAEL, this finding is not considered to be indicative of 
susceptibility. In the multi-generation reproduction toxicity study, 
thyroid toxicity was observed in parental animals at the same dose 
eliciting decreased body weights in the offspring. Reproductive effects 
manifested as decreases in implantations and increases in 
postimplantation loss occurred at a dose level approximately 4x higher 
than the parental and offspring LOAELs.
    The only potential sign of neurotoxicity was a decrease in total 
motor activity and total number of rearings observed in the acute 
neurotoxicity study in rats. However, given that the liver is the 
target tissue, these effects may be nonspecific effects secondary to 
general toxicity. These effects were not observed in the subchronic 
neurotoxicity or any other studies in the database.
    In a 28-day dermal toxicity study, no hazard was identified at the 
limit dose 1,000 milligrams/kilogram/day (mg/kg/day). Similarly, an 
immunotoxicity study in rats did not indicate that the immune system is 
a target for fenpyrazamine toxicity.
    Although an increase in the incidence of hepatocellular and thyroid 
follicular carcinomas was noted in the chronic/carcinogenicity study in 
rats, the concern for these findings is low based on the following 
weight of evidence considerations:
    1. The marginal increases occurred only at the high dose;
    2. There was no reduction in the latency period (i.e., tumors were 
seen only at the terminal sacrifice); and
    3. The incidences were only slightly outside the historical control 
range of the testing laboratories.
    In addition, no neoplastic lesions attributable to treatment were 
observed in the carcinogenicity study in mice and no indication of 
mutagenicity was noted in the mutagenicity battery. Based on this 
evidence, in accordance with the Agency's 2005 Guidelines for Cancer 
Risk Assessment, EPA classified fenpyrazamine as ``Not Likely to be 
Carcinogenic to Humans''.
    Specific information on the studies received and the nature of the 
adverse effects caused by fenpyrazamine as well as the no-observed-
adverse-effect-level (NOAEL) and the lowest-observed-adverse-effect-
level (LOAEL) from the toxicity studies can be found at https://www.regulations.gov in section 4.5.4 in the document ``Human Health 
Risk Assessment for the Section 3 Registration and Establishment of 
Tolerances on Almond, Small Fruit Climbing Subgroup 13-07F, Head and 
Leaf Lettuce, and Low Growing Berry Subgroup 13-07G, Bushberry Subgroup 
13-07B, Caneberry Subgroup 13-07A, Ginseng, and Pistachio'' in docket 
ID number EPA-HQ-OPP-2011-0357.

B. Toxicological Points of Departure/Levels of Concern

    Once a pesticide's toxicological profile is determined, EPA 
identifies toxicological points of departure (POD) and levels of 
concern to use in evaluating the risk posed by human exposure to the 
pesticide. For hazards that have a threshold below which there is no 
appreciable risk, the toxicological POD is used as the basis for 
derivation of reference values for risk assessment. PODs are developed 
based on a careful analysis of the doses in each toxicological study to 
determine the dose at which no adverse effects are observed (the NOAEL) 
and the lowest dose at which adverse effects of concern are identified 
(the LOAEL). Uncertainty/safety factors are used in conjunction with 
the POD to calculate a safe exposure level--generally referred to as a 
population-adjusted dose (PAD) or a reference dose (RfD)--and a safe 
margin of exposure (MOE). For non-threshold risks, the Agency assumes 
that any amount of exposure will lead to some degree of risk. Thus, the 
Agency estimates risk in terms of the probability of an occurrence of 
the adverse effect expected in a lifetime. For more information on the 
general principles EPA uses in risk characterization and a complete 
description of the risk assessment process, see https://www.epa.gov/pesticides/factsheets/riskassess.htm.
    A summary of the toxicological endpoints for fenpyrazamine used for 
human risk assessment is shown in the following Table.

C. Exposure Assessment

    1. Dietary exposure from food and feed uses. In evaluating dietary 
exposure to fenpyrazamine, EPA considered exposure under the 
petitioned-for tolerances in 40 CFR 180. EPA assessed dietary exposures 
from fenpyrazamine in food as follows:
    i. Acute exposure. Quantitative acute dietary exposure and risk 
assessments are performed for a food-use pesticide, if a toxicological 
study has indicated the possibility of an effect of concern occurring 
as a result of a 1-day or single exposure. Such effects were identified 
for fenpyrazamine. In estimating acute dietary exposure, EPA used food 
consumption information from the 2003 to 2008 United States Department 
of Agriculture (USDA) National Health and Nutrition Examination Survey, 
What We Eat in America, (NHANES/WWEIA). For residue levels in food, EPA 
assumed 100 percent crop treated (PCT) and tolerance level residues of 
parent fenpyrazamine plus the maximum residue of S-2188-DC (expressed 
as parent fenpyrazamine) observed in the crop field trials for the 
proposed uses.
    ii. Chronic exposure. In conducting the chronic dietary exposure 
assessment EPA used the food consumption data from the 2003 to 2008 
United States Department of Agriculture (USDA) National Health and 
Nutrition Examination Survey, What We Eat in America, (NHANES/WWEIA). 
For residue levels in food, EPA assumed 100 PCT and tolerance level 
residues of parent fenpyrazamine plus the maximum residue of S-2188-DC 
(expressed as parent fenpyrazamine) observed in the crop field trials 
for the proposed uses.
    iii. Cancer. Based on the data summarized in Unit III.A., EPA has 
concluded that fenpyrazamine does not pose a cancer risk to humans. 
Therefore, a dietary exposure assessment for the purpose of assessing 
cancer risk is unnecessary.
    iv. Anticipated residue and PCT information. EPA did not use 
anticipated residue or PCT information in the dietary assessment for 
fenpyrazamine. Tolerance level residues and 100 PCT were assumed for 
all food commodities.
    2. Dietary exposure from drinking water. The Agency used screening 
level water exposure models in the dietary exposure analysis and risk 
assessment for fenpyrazamine in drinking water. These simulation models 
take into account data on the physical, chemical, and fate/transport 
characteristics of fenpyrazamine. Further information regarding EPA 
drinking water models used in pesticide exposure assessment can be 
found at https://www.epa.gov/oppefed1/models/water/index.htm.
    Based on the Tier 1 FQPA Index Reservoir Screening Tool (FIRST v. 
1.1.1, released March 26, 2008) for surface water and the Screening 
Concentration in Ground Water (SCI-GROW) model for ground water, the 
estimated drinking water concentrations (EDWCs) of fenpyrazamine for 
acute exposures are estimated to be 213.5 parts per billion (ppb) for 
surface water and 1.31 ppb for ground water. The chronic exposures are 
estimated to be 72.5 ppb for surface water and 1.31 ppb for ground 
water.
    Modeled estimates of drinking water concentrations were directly 
entered into the dietary exposure model. For acute dietary risk 
assessment, the water concentration value of 213.5 ppb was used to 
assess the contribution to drinking water. For chronic dietary risk 
assessment, the water concentration of value 72.5 ppb was used to 
assess the contribution to drinking water.
    3. From non-dietary exposure. The term ``residential exposure'' is 
used in this document to refer to non-occupational, non-dietary 
exposure (e.g., for lawn and garden pest control, indoor pest control, 
termiticides, and flea and tick control on pets). Fenpyrazamine is not 
registered for any specific use patterns that would result in 
residential exposure.
    4. Cumulative effects from substances with a common mechanism of 
toxicity. Section 408(b)(2)(D)(v) of FFDCA requires that, when 
considering whether to establish, modify, or revoke a tolerance, the 
Agency consider ``available information'' concerning the cumulative 
effects of a particular pesticide's residues and ``other substances 
that have a common mechanism of toxicity.'' EPA has not found 
fenpyrazamine to share a common mechanism of toxicity with any other 
substances, and fenpyrazamine does not appear to produce a toxic 
metabolite produced by other substances. For the purposes of this 
tolerance action, therefore, EPA has assumed that fenpyrazamine does 
not have a common mechanism of toxicity with other substances. For 
information regarding EPA's efforts to determine which chemicals have a 
common mechanism of toxicity and to evaluate the cumulative effects of 
such chemicals, see EPA's Web site at https://www.epa.gov/pesticides/cumulative.

D. Safety Factor for Infants and Children

    1. In general. Section 408(b)(2)(C) of FFDCA provides that EPA 
shall apply an additional tenfold (10X) margin of safety for infants 
and children in the case of threshold effects to account for prenatal 
and postnatal toxicity and the completeness of the database on toxicity 
and exposure unless EPA determines based on reliable data that a 
different margin of safety will be safe for infants

[[Page 14464]]

and children. This additional margin of safety is commonly referred to 
as the FQPA Safety Factor (SF). In applying this provision, EPA either 
retains the default value of 10X, or uses a different additional safety 
factor when reliable data available to EPA support the choice of a 
different factor.
    2. Prenatal and postnatal sensitivity. There is no evidence of 
increased pre- and/or postnatal susceptibility based on the results of 
the rat and rabbit prenatal developmental toxicity studies, and the rat 
2-generation reproductive toxicity study.
    3. Conclusion. EPA has determined that reliable data show the 
safety of infants and children would be adequately protected if the 
FQPA SF were reduced to 1x. That decision is based on the following 
findings:
    i. The toxicity database for fenpyrazamine is complete.
    ii. There is no evidence of increased pre- and/or postnatal 
susceptibility for fenpyrazamine.
    iii. There is no residual uncertainty in the exposure database for 
fenpyrazamine with respect to dietary (food and water) exposure. The 
dietary food exposure assessments were performed based on 100 PCT and 
tolerance-level residues of parent fenpyrazamine plus the maximum 
reside of the metabolite S-2188-DC, empirical concentration factors and 
default processing factors. EPA made conservative (protective) 
assumptions in the ground and surface water modeling used to assess 
exposure to fenpyrazamine in drinking water. These assessments will not 
underestimate the exposure and risks posed by fenpyrazamine.

E. Aggregate Risks and Determination of Safety

    EPA determines whether acute and chronic dietary pesticide 
exposures are safe by comparing aggregate exposure estimates to the 
aPAD and chronic population-adjusted dose (cPAD). For linear cancer 
risks, EPA calculates the lifetime probability of acquiring cancer 
given the estimated aggregate exposure. Short-term, intermediate-term, 
and chronic-term risks are evaluated by comparing the estimated 
aggregate food, water, and residential exposure to the appropriate PODs 
to ensure that an adequate MOE exists. Since there are no residential 
uses proposed for fenpyrazamine, the aggregate risks are equal to the 
dietary and drinking water assessments.
    1. Acute risk. Using the exposure assumptions discussed in this 
unit for acute exposure, the acute dietary exposure from food and water 
to fenpyrazamine will occupy 9.2% of the aPAD for children 1-2 years 
old, the population group receiving the greatest exposure.
    2. Chronic risk. Using the exposure assumptions described in this 
unit for chronic exposure, EPA has concluded that chronic exposure to 
fenpyrazamine from food and water will utilize 7.3% of the cPAD for 
children 1-2 years old, the population group receiving the greatest 
exposure.
    3. Short-term and intermediate-term risk. Short-term and 
intermediate-term aggregate exposure takes into account short-term or 
intermediate-term residential exposure plus chronic exposure to food 
and water (considered to be a background exposure level). Fenpyrazamine 
is not registered for any use patterns that would result in short-term 
or intermediate-term residential exposure. Short-term and intermediate-
term risk is assessed based on short-term or intermediate-term 
residential exposure plus chronic dietary exposure. Because there is no 
short-term or intermediate-term residential exposure and chronic 
dietary exposure has already been assessed under the appropriately 
protective cPAD (which is at least as protective as the POD used to 
assess short-term risk), no further assessment of short-term or 
intermediate-term risk is necessary, and EPA relies on the chronic 
dietary risk assessment for evaluating short-term and intermediate-term 
risk for fenpyrazamine.
    4. Aggregate cancer risk for U.S. population. Based on the results 
of two adequate rodent carcinogenicity studies, fenpyrazamine is not 
expected to pose a cancer risk to humans.
    5. Determination of safety. Based on these risk assessments, EPA 
concludes that there is a reasonable certainty that no harm will result 
to the general population, or to infants and children from aggregate 
exposure to fenpyrazamine residues.

IV. Other Considerations

A. Analytical Enforcement Methodology

    Parent fenpyrazamine only is the residue of concern for tolerance 
enforcement purposes. Valent U.S.A. Corporation has submitted the 
results of an independent laboratory validation (ILV) by liquid 
chromatography and mass spectrometry (LC/MS/MS), Method RM-45C-1, 
titled ``Determination of S-2188 and S-2188-DC in crops''. The method 
is considered adequate for enforcement of tolerances in plant 
commodities.
    The method may be requested from: Chief, Analytical Chemistry 
Branch, Environmental Science Center, 701 Mapes Rd., Ft. Meade, MD 
20755-5350; telephone number: (410) 305-2905; email address: 
residuemethods@epa.gov.

B. International Residue Limits

    In making its tolerance decisions, EPA seeks to harmonize U.S. 
tolerances with international standards whenever possible, consistent 
with U.S. food safety standards and agricultural practices. EPA 
considers the international maximum residue limits (MRLs) established 
by the Codex Alimentarius Commission (Codex), as required by FFDCA 
section 408(b)(4). The Codex Alimentarius is a joint United Nations 
Food and Agriculture Organization/World Health Organization food 
standards program, and it is recognized as an international food safety 
standards-setting organization in trade agreements to which the United 
States is a party. EPA may establish a tolerance that is different from 
a Codex MRL; however, FFDCA section 408(b)(4) requires that EPA explain 
the reasons for departing from the Codex level.
    Fenpyrazamine is a new active ingredient and MRLs have not been 
established by Codex, Canada, or Mexico for the commodities proposed 
for registration in the US.

C. Revisions to Petitioned-For Tolerances

    The Agency established parent fenpyrazamine only as the residue of 
concern for tolerance enforcement in plants and tolerances were 
recommended accordingly. These differ from the tolerances proposed by 
the registrant, which are based on residues of parent fenpyrazamine and 
the metabolite S-2188-DC expressed as fenpyrazamine. In addition, the 
Organization for the Economical Cooperation and Development (OECD) 
calculation procedures were used to estimate the tolerances and based 
on these procedures, the Agency has determined that the lettuce, head 
tolerance should be lowered from 2.0 to 1.5 ppm; lettuce, leaf from 2.5 
ppm to 2 ppm; Caneberry subgroup 13-07A from 7.0 ppm to 5 ppm; 
Bushberry subgroup 13-07B from 7.0 ppm to 5 ppm; small fruit vine 
climbing subgroup except fuzzy kiwi fruit, subgroup 13-07F from 3.5 ppm 
to 3 ppm; and grape, juice from 7.0 ppm to 4 ppm. Finally, the 
submitted grape processing data indicate that residues of parent 
fenpyrazamine only concentrate in raisins at 1.1x. Therefore, the 
concentration factor for raisin is not

[[Page 14465]]

high enough to justify the need of a separate tolerance for raisins.

V. Conclusion

    Therefore, tolerances are established for residues of 
fenpyrazamine, S-allyl 5-amino-2-isopropyl-4-(2-methylphenyl)-3-oxo-
2,3-dihydropyrazole-1-carbothioate, in or on Almond at 0.02 ppm; 
almond, hulls at 1.5 ppm; pistachio at 0.02 ppm; lettuce, head at 1.5 
ppm; lettuce, leaf at 2 ppm; Caneberry subgroup 13-07A at 5 ppm; 
Bushberry subgroup 13-07B at 5 ppm; small fruit vine climbing subgroup 
except fuzzy kiwi fruit, subgroup 13-07F at 3 ppm; grape, juice at 4 
ppm; low growing berry subgroup 13-07G at 3 ppm; and ginseng at 0.7 
ppm.

VI. Statutory and Executive Order Reviews

    This final rule establishes tolerances under FFDCA section 408(d) 
in response to a petition submitted to the Agency. The Office of 
Management and Budget (OMB) has exempted these types of actions from 
review under Executive Order 12866, entitled ``Regulatory Planning and 
Review'' (58 FR 51735, October 4, 1993). Because this final rule has 
been exempted from review under Executive Order 12866, this final rule 
is not subject to Executive Order 13211, entitled ``Actions Concerning 
Regulations That Significantly Affect Energy Supply, Distribution, or 
Use'' (66 FR 28355, May 22, 2001) or Executive Order 13045, entitled 
``Protection of Children from Environmental Health Risks and Safety 
Risks'' (62 FR 19885, April 23, 1997). This final rule does not contain 
any information collections subject to OMB approval under the Paperwork 
Reduction Act (PRA) (44 U.S.C. 3501 et seq.), nor does it require any 
special considerations under Executive Order 12898, entitled ``Federal 
Actions to Address Environmental Justice in Minority Populations and 
Low-Income Populations'' (59 FR 7629, February 16, 1994).
    Since tolerances and exemptions that are established on the basis 
of a petition under FFDCA section 408(d), such as the tolerance in this 
final rule, do not require the issuance of a proposed rule, the 
requirements of the Regulatory Flexibility Act (RFA) (5 U.S.C. 601 et 
seq.), do not apply.
    This final rule directly regulates growers, food processors, food 
handlers, and food retailers, not States or tribes, nor does this 
action alter the relationships or distribution of power and 
responsibilities established by Congress in the preemption provisions 
of FFDCA section 408(n)(4). As such, the Agency has determined that 
this action will not have a substantial direct effect on States or 
tribal governments, on the relationship between the national government 
and the States or tribal governments, or on the distribution of power 
and responsibilities among the various levels of government or between 
the Federal Government and Indian tribes. Thus, the Agency has 
determined that Executive Order 13132, entitled ``Federalism'' (64 FR 
43255, August 10, 1999) and Executive Order 13175, entitled 
``Consultation and Coordination with Indian Tribal Governments'' (65 FR 
67249, November 9, 2000) do not apply to this final rule. In addition, 
this final rule does not impose any enforceable duty or contain any 
unfunded mandate as described under Title II of the Unfunded Mandates 
Reform Act of 1995 (UMRA) (2 U.S.C. 1501 et seq.).
    This action does not involve any technical standards that would 
require Agency consideration of voluntary consensus standards pursuant 
to section 12(d) of the National Technology Transfer and Advancement 
Act of 1995 (NTTAA) (15 U.S.C. 272 note).

VII. Congressional Review Act

    Pursuant to the Congressional Review Act (5 U.S.C. 801 et seq.), 
EPA will submit a report containing this rule and other required 
information to the U.S. Senate, the U.S. House of Representatives, and 
the Comptroller General of the United States prior to publication of 
the rule in the Federal Register. This action is not a ``major rule'' 
as defined by 5 U.S.C. 804(2).
