Summary of Petitioned-for Tolerance
In the Federal Register of August 10, 2011 (76 FR 49396) (FRL-8882-
8), EPA issued a notice pursuant to section 408(d)(3) of FFDCA, 21 U.S.C. 346a(d)(3), announcing the filing of a pesticide petition (PP 7F7260) by BASF Corporation, P.O. Box 13528, Research Triangle Park, NC 27709. The petition requested that 40 CFR part 180 be amended by establishing tolerances for residues of the insecticide metaflumizone, in or on: Fruit, citrus, group 10 at 0.04 ppm; nut, tree, group 14 at 0.04 ppm; almond, hulls at 0.04 ppm; and grape at 0.04 ppm. That notice referenced a summary of the petition prepared by BASF Corporation, the registrant, which is available in the docket, http://www.regulations.gov. There were no comments received in response to the notice of filing.

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 section 408(b)(2)(D) of FFDCA, and the factors specified in section 408(b)(2)(D) of FFDCA, 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 metaflumizone including exposure resulting from the tolerances established by this action. EPA's assessment of exposures and risks associated with metaflumizone follows.
-
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.
Hematotoxicity (toxicity of the blood) was the primary toxic effect of concern following subchronic or chronic oral exposures to metaflumizone. Splenic extramedullary hematopoiesis, increased hemosiderin, and anemia were the most common hematotoxic effects reported after repeated oral dosing with metaflumizone. The postulated pesticidal mode of action of metaflumizone involves inhibition of sodium channels in target insect species; however, in mammals (rats), there were only clinical signs of neurotoxicity (i.e., piloerection and body temperature variations) with no neuropathology in the presence of systemic toxicity (e.g., recumbency and poor general state) following acute or repeated exposures. Similarly, several immune system organs seem to be affected following metaflumizone administration via the oral, dermal, and inhalation routes (e.g., the presence of macrophages in the thymus, lymphocyte necrosis in the mesenteric lymph nodes,
Page 10383
and diffuse atrophy of the mandibular); however, there was no evidence of any functional deficits at the highest dose tested (HDT) in a recently submitted and reviewed guideline immunotoxicity study. Therefore, the clinical neurotoxicity signs and the effects on the immune system organs following metaflumizone administration are likely to be secondary to the hematotoxic effects. Metaflumizone induced an increased incidence of a missing subclavian artery at a relatively high dose that also caused severe maternal toxicity (e.g., late term abortions) in the developmental toxicity study in rabbits. There was no evidence (quantitative or qualitative) of increased susceptibility following in utero exposures to rats or rabbit and following pre- and post natal exposures. There was no evidence that metaflumizone is genotoxic and carcinogenicity studies with mice and rabbits were negative.
Specific information on the studies received and the nature of the adverse effects caused by metaflumizone 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 http://www.regulations.gov in the document entitled ``Metaflumizone. Revised Human-Health Risk Assessment Associated with a Section 3 Registration for a Fire Ant Bait for Application to Citrus, Tree Nuts, and Grape, and a new Section 3 Registration for a Fly Bait for Application around Industrial, Commercial, Agricultural, and Recreational Facilities/
Structures and Premises'' in docket ID number EPA-HQ-OPP-2008-0168.
-
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 http://www.epa.gov/pesticides/factsheets/riskassess.htm.
A summary of the toxicological endpoints for metaflumizone used for human risk assessment is provided in this unit:
i. Acute dietary endpoint (general population including infants and children). An acute dietary endpoint was not established for this population group since an endpoint of concern (effect) attributable to a single dose was not identified in the database. Studies considered for this endpoint included the acute neurotoxicity study in which no toxicity was observed at any dose including the HDT, which is the limit dose (1,000 milligrams/kilograms/day (mg/kg/day)).
ii. Acute dietary endpoint (females 13-49 years old). This endpoint was established based on a developmental effect observed in the rabbit developmental toxicity study that can be potentially due to a single dose of metaflumizone. This effect consisted of an increased incidence of an absent subclavian artery in the offspring at the LOAEL of 300 mg/
kg body/weight/day (bw/day) metaflumizone (NOAEL = 100 mg/kg bw/day). The rat developmental toxicity study was also considered for this endpoint; however, no developmental effects were observed in this study at the HDT of 120 mg/kg bw/day metaflumizone. A combined uncertainty factor of 300 was applied to account for interspecies (10X) and intraspecies (10X) extrapolation and a Food Quality Protection Act (FQPA) safety factor of 3X. Thus, the acute population adjusted dose (aPAD) for females 13-49 years old is estimated to be 0.33 mg/kg bw/
day.
iii. Chronic dietary endpoint. This endpoint was established based on the systemic toxicity observed in the chronic toxicity study with dogs. At the LOAEL of 30 mg/kg bw/day (NOAEL = 12 mg/kg bw/day), the effects consisted of reduced general health condition, slight to severe ataxia, recumbency, and severe salivation, slight decreases in mean corpuscular hemoglobin concentration and total hemoglobin, leading to increased plasma bilirubin, increased urinary urobilinogen, and increased hemosiderin in the liver. A combined uncertainty factor of 300 was applied to account for interspecies (10X) and intraspecies (10X) extrapolation and an FQPA safety factor of 3X. Thus, the chronic population adjusted dose (cPAD) is estimated to be 0.040 mg/kg bw/day.
iv. Incidental oral (short- and intermediate-term). This endpoint was selected on the basis of the maternal effects observed in the rat 2-generation reproductive toxicity study at the LOAEL of 50 mg/kg bw/
day metaflumizone (NOAEL = 20 mg/kg bw/day). Maternal toxicity consisted of poor general health and body weight deficits which were also associated with improper nursing behavior. Similar effects were also noted in a developmental neurotoxicity study (gavage, range finding) also considered for this endpoint. In this study, poor maternal health was also observed at the LOAEL of 120 mg/kg bw/day metaflumizone (NOAEL = 80 mg/kg bw/day). Both studies considered for this endpoint achieved a clear NOAEL for the offspring effects, but the NOAEL of 20 mg/kg bw/day for the 2-generation reproductive toxicity study is considered more protective. The Agency's level of concern for this scenario is 300 based on a 10X intraspecies factor, a 10X interspecies factor, and an FQPA safety factor of 3X.
v. Dermal (short- and intermediate-term). This endpoint was based on a rat 90-day dermal toxicity study in which deficits in body weight, body-weight gain and food consumption (in males and females); anogenital smearing; increased macrophages in the thymus; lymphocyte necrosis in the mesenteric lymph nodes; diffuse atrophy of the mandibular lymph node; and increased hemosiderin in the liver (females only) were observed at the LOAEL of 300 mg/kg bw/day (NOAEL = 100 mg/kg bw/day). The Agency's level of concern for this scenario is 100 based on a 10X interspecies factor, and a 10X intraspecies factor.
vi. Inhalation (short- and intermediate-term). There is a 28-day inhalation study for this exposure scenario. There was no NOAEL identified for female rats. At the LOAEL of 0.10 mg/Liter (L) metaflumizone (NOAEL = 0.03 mg/L), histopathology of the nasal tissues, lungs, thymus, prostate, and adrenal cortex was observed in males. The LOAEL identified in females resulted in lymphocyte necrosis in the mesenteric lymph node. The Agency's level of concern for this scenario is 1,000 based on a 10X interspecies factor, a 10X intraspecies factor, and an FQPA safety factor of 10X. Route-specific toxicity studies were selected for assessment of
Page 10384
short-intermediate-term dermal, inhalation, and oral exposures. Short-
intermediate-term dermal and inhalation exposures can be aggregated based on the immunotoxic effects seen at the LOAEL in the selected studies. Short/intermediate-term oral, dermal, and inhalation exposures can be aggregated based on the decreased body weight or decreased body-
weight gain effects seen at the LOAEL in the selected oral and dermal studies and at doses above the LOAEL in the selected inhalation study.

Exposure Assessment
-
Dietary exposure from food and feed uses. In evaluating dietary exposure to metaflumizone, EPA considered exposure under the petitioned-for tolerances. EPA assessed dietary exposures from metaflumizone 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 metaflumizone. In estimating acute dietary exposure, EPA used food consumption information from the United States Department of Agriculture (USDA) 1994-1996 and 1998 Nationwide Continuing Surveys of Food Intake by Individuals (CSFII). As to residue levels in food, EPA assumed tolerance-level residues. It was further assumed that 100% of crops with the requested uses of metaflumizone were treated.
ii. Chronic exposure. In conducting the chronic dietary exposure assessment EPA used the food consumption data from the USDA 1994-1996 and 1998 CSFII. As to residue levels in food, EPA assumed tolerance-
level residues. It was further assumed that 100% of crops with the requested uses of metaflumizone were treated.
iii. Cancer. Based on the data summarized in Unit III.A., EPA has concluded that metaflumizone 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 percent crop treated (PCT) information. EPA did not use anticipated residue or PCT information in the dietary assessment for metaflumizone. Tolerance level residues and/or 100 PCT were assumed for all food commodities.
-
Dietary exposure from drinking water. The Agency used screening level water exposure models in the dietary exposure analysis and risk assessment for metaflumizone in drinking water. These simulation models take into account data on the physical, chemical, and fate/transport characteristics of metaflumizone. Further information regarding EPA drinking water models used in pesticide exposure assessment can be found at http://www.epa.gov/oppefed1/models/water/index.htm.
Based on the Pesticide Root Zone Model/Exposure Analysis Modeling System (PRZM/EXAMS) and Screening Concentration in Ground Water (SCI-
GROW) models, the estimated drinking water concentrations (EDWCs) of metaflumizone for acute exposures are estimated to be 1.14 parts per billion (ppb) for surface water and 0.00214 ppb for ground water. The EDWCs of metaflumizone for chronic exposures for non-cancer chronic assessments are estimated to be 0.597 ppb for surface water and 0.00214 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 1.14 ppb was used to assess the contribution to drinking water. For chronic dietary risk assessment, the water concentration of value 0.597 ppb was used to assess the contribution to drinking water.
-
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). Metaflumizone is currently registered for the following uses that could result in residential exposures: Pet spot-on products to control fleas on dogs and cats; fire ant bait products for application to lawns, landscapes, golf courses, and other non-cropland area. In addition, a pending fly bait product is proposed for use in areas where people may be present; therefore, a residential exposure assessment was performed for this use.
EPA assessed residential exposure using the following assumptions: For the pet spot-on products, residential handler exposure is not expected, because the product is applied directly from a tube to the pet. Pet spot-on applications are expected to result in short- and intermediate-term post-application dermal exposure to all populations, and incident oral exposure (i.e., hand-to-mouth) for children 3 to 1 are not a risk of concern).
Using the exposure assumptions described in this unit for short-
term exposures, EPA has concluded the combined short-term food, water, and residential exposures result in aggregate risk indices of 3 for the general population, and 2 for children 1-2 years old. Since the LOCs for the dermal, inhalation and incidental oral routes are not the same (dermal LOC = 100, inhalation LOC = 1,000, and incidental oral LOC = 300), these routes were combined using the aggregate risk index approach. Because EPA's LOC for metaflumizone is an aggregate risk index less than 1, the aggregate risks are not of concern. These aggregate risk indices utilize residential exposure estimates from the pet spot-on products, which represent the worst-case exposure scenario. However, it should be noted that all registered pet spot-on products containing metaflumizone are pending voluntary cancellation; therefore, these aggregate risk indices can be considered conservative.
-
Intermediate-term risk. Intermediate-term aggregate exposure takes into account intermediate-term residential exposure plus chronic exposure to food and water (considered to be a background exposure level). Metaflumizone is currently registered for uses that could result in intermediate-term residential exposure;
Page 10386
however, since the PODs for the short- and intermediate-term durations are the same for metaflumizone, the short-term aggregate assessment is protective of longer-term exposures.
-
Aggregate cancer risk for U.S. population. Based on the lack of evidence of carcinogenicity in two adequate rodent carcinogenicity studies, metaflumizone is not expected to pose a cancer risk to humans.
-
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 metaflumizone residues.

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.
-
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 U.N. 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.
The Codex has not established a MRL for metaflumizone.
-
-
Conclusion
Therefore, tolerances are established for residues of metaflumizone, (E and Z isomers; 2-2-(4-cyanophenyl)-1-3-
(trifluoromethyl) phenylethylidene-N-4-(trifluoromethoxy)phenyl hydrazinecarboxamide) and its metabolite 4-{2-oxo-2-3-
(trifluoromethyl) phenylethyl{time} -benzonitrile, in or on: Fruit, citrus, group 10 at 0.04 ppm; nut, tree, group 14 at 0.04 ppm; almond, hulls at 0.04 ppm; and grape at 0.04 ppm.

Statutory and Executive Order Reviews
This final rule establishes tolerances under section 408(d) of FFDCA 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 section 408(d) of FFDCA, 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 section 408(n)(4) of FFDCA. 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) (Pub. L. 104-4).
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), Public Law 104-113, section 12(d) (15 U.S.C. 272 note).

Congressional Review Act
The Congressional Review Act, 5 U.S.C. 801 et seq., generally provides that before a rule may take effect, the agency promulgating the rule must submit a rule report to each House of the Congress and to the Comptroller General of the United States. 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 this final rule in the Federal Register. This final rule is not a ``major rule'' as defined by 5 U.S.C. 804(2).
