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 
                    ( print page 47059)
                    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 submitted in support of this action. EPA has sufficient data to assess the hazards of and to make a determination on aggregate exposure for the petitioned-for tolerances for residues of the insecticide flubendiamide. EPA's assessment of exposures and risks associated with establishing tolerances 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. Flubendiamide has low acute toxicity via the oral and dermal routes, is only a slight eye irritant, is non-irritating to the dermis and tests negative for skin sensitization. In the longer-term studies in the flubendiamide mammalian toxicology database, the primary target organs identified were the liver, thyroid, kidney and eyes. Liver effects reported in rats, mice and/or dogs include organ weight increase, periportal fatty change, hypertrophy and minimal foci of cellular alteration. Thyroid effects include organ weight increase, follicular cell hypertrophy and slight perturbations of triiodothyronine (TC) and thyroid stimulating hormone (TSH) in the rat and mouse. Kidney effects include increases in absolute and/or relative to body kidney weights and chronic nephropathy in the rat. Eye effects include eye enlargement, opacity and exophthalmus with hemorrhage and appear only in rat pups. Other changes include mild microcytic anemia, decreased serum triglycerides and cholesterol in female rat, increased gamma glutamyl peptidase, alkaline phosphatase and shortened activated prothrombin time in dogs, and adrenal weight increase and an increase in adrenal cortical cell hypertrophy in dogs. The hazard assessment indicated potential toxicity resulting from exposure to flubendiamide via different routes over different durations. The observed eye effects were selected as a critical effect for the acute dietary exposure scenario; whereas liver and thyroid effects were determined critical for the chronic dietary exposure scenario. Short-term and intermediate-term dermal risks were also based on liver and thyroid effects as well as blood effects. Short-term and intermediate-term inhalation risks are based on liver toxicity as well as adrenal weight increase and an increase in adrenal cortical cell hypertrophy. There was no evidence of carcinogenicity in rats and mice up to the limit dose at 24- and 18-months, respectively. Flubendiamide was determined to be non-mutagenic in bacteria, negative in an 
                    *in vivo*
                     mammalian cytogenetics assay and did not cause unscheduled DNA synthesis (repair of DNA damage) in mammalian cells 
                    *in vitro*. Overall, there was no clear evidence that flubendiamide was either mutagenic or clastogenic in either 
                    *in vivo*
                     or 
                    *in vitro*
                     assays. The cancer classification is “Not Likely to be Carcinogenic to Humans.” More detailed information on the studies received and the nature of the adverse effects caused by flubendiamide 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 in the document entitled, “Flubendiamide: Human Health Risk Assessment for Proposed Uses on Corn, Cotton, Tobacco, Tree fruit, Tree nuts, Vine crops and Vegetable crops,” dated April 3, 2008, by going to

Double-click on the document to view the referenced information on pages 65-70 of 105. B. Toxicological Endpoints For hazards that have a threshold below which there is no appreciable risk, a toxicological point of departure (POD) is identified as the basis for derivation of reference values for risk assessment. The POD may be defined as the highest dose at which no adverse effects are observed (the NOAEL) in the toxicology study identified as appropriate for use in risk assessment. However, if a NOAEL cannot be determined, the lowest dose at which adverse effects of concern are identified (the LOAEL) or a Benchmark Dose (BMD) approach is sometimes used for risk assessment. Uncertainty/safety factors (UFs) are used in conjunction with the POD to take into account uncertainties inherent in the extrapolation from laboratory animal data to humans and in the variations in sensitivity among members of the human population as well as other unknowns. Safety is assessed for acute and chronic dietary risks by comparing aggregate food and water exposure to the pesticide to the acute population adjusted dose (aPAD) and chronic population adjusted dose (cPAD). The aPAD and cPAD are calculated by dividing the POD by all applicable UFs. Aggregate short-term, intermediate-term and chronic-term risks are evaluated by comparing food, water and residential exposure to the POD to ensure that the margin of exposure (MOE) called for by the product of all applicable UFs is not exceeded. This latter value is referred to as the Level of Concern (LOC). 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 greater than that 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, refer to

                    *Dietary exposure from food and feed uses*. In evaluating dietary exposure to flubendiamide, EPA considered exposure under the 
                    ( print page 47060)
                    petitioned-for tolerances and assessed dietary exposures from flubendiamide 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. In estimating acute dietary exposure, EPA used food consumption information from the Dietary Exposure Evaluation Model-Food Commodity Intake Database (DEEM-FCIDTM
                    , Version 2.03), which incorporates food consumption data from the U.S. Department of Agriculture's (USDA's) Nationwide Continuing Surveys of Food Intakes by Individuals (CSFII) from 1994-1996 and 1998. The acute assessments assumed that 100% of crops with requested uses of flubendiamide are treated and that all treated crops contain residues at tolerance-level. In addition, tolerance-level residues for livestock commodities were included in these analyses to account for the potential transfer of plant residues to livestock tissues. ii. 
                    *Chronic exposure*
                    . In conducting the chronic dietary exposure assessment, EPA used DEEM-FCIDTM
                    , Version 2.03, which incorporates food consumption data from the USDA's CSFII from 1994-1996 and 1998. The chronic assessments assumed that 100% of crops with requested uses of flubendiamide are treated and that all treated crops contain residues at the average residue levels found in the crop field trials and experimentally-determined processing factors where available. In addition, average-level residues for livestock commodities were also included in these analyses to account for the potential transfer of plant residues to livestock tissues. iii. 
                    *Cancer*. As explained in Unit III.A., flubendiamide is considered to be “Not Likely to be Carcinogenic to Humans.” As a result, cancer exposure assessment is not needed for flubendiamide. iv. 
                    *Anticipated residue information*. Section 408(b)(2)(E) of FFDCA authorizes EPA to use available data and information on the anticipated residue levels of pesticide residues in food and the actual levels of pesticide residues that have been measured in food. If EPA relies on such information, EPA must require pursuant to FFDCA section 408(f)(1) that data be provided 5 years after the tolerance is established, modified or left in effect, demonstrating that the levels in food are not above the levels anticipated. For the present action, EPA will issue such data call-ins as are required by FFDCA section 408(b)(2)(E) and authorized under FFDCA section 408(f)(1). Data will be required to be submitted no later than 5 years from the date of issuance of these tolerances. 2. 
                    *Dietary exposure from drinking water*. The Agency used screening level water exposure models in the dietary exposure analysis and risk assessment for flubendiamide in drinking water. These simulation models take into account data on the physical, chemical and fate/transport characteristics of flubendiamide. Flubendiamide is persistent and potentially mobile in terrestrial and aquatic environments. These fate properties suggest that it has a potential to move into surface and ground water. The Agency lacks sufficient monitoring exposure data for use in risk assessments, as flubendiamide is a new active ingredient. Because the Agency does not have comprehensive monitoring data, drinking water concentration estimates are made by reliance on simulation or modeling, taking into account data on the physical and fate characteristics of flubendiamide. 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 the Screening Concentration in Ground Water (SCI-GROW) model, the estimated drinking water concerns (EDWCs) of flubendiamide for acute exposures are estimated to be 12.93 parts per billion (ppb) for surface water and 0.06 ppb for ground water. For chronic exposures for non-cancer assessments, the EDWCs are estimated to be 11.95 ppb for surface water and 0.06 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 12.93 ppb was used to assess the contribution to drinking water. For chronic dietary risk assessment, the water concentration of value 11.95 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). Flubendiamide is not registered for any specific use patterns that would result in residential exposure. That is, no residential uses are being requested for flubendiamide at this time; therefore, no residential risk assessment has been conducted. 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 flubendiamide to share a common mechanism of toxicity with any other substances, and flubendiamide does not appear to produce a toxic metabolite produced by other substances. For the purposes of this tolerance action; therefore, EPA has assumed that flubendiamide 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 website at 
                    *http://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 ten-fold (10x) margin of safety for infants and children in the case of threshold effects to account for pre-natal and/or post-natal 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 and children. This additional margin of safety is commonly referred to as the Food Quality Protection Act Safety Factor (FQPA SF). In applying this provision, EPA either retains the default value of 10x or uses a different additional SF when reliable data available to EPA support the choice of a different factor. 2. 
                    *Pre-natal and post-natal sensitivity*. While both the rat and rabbit developmental studies did not identify teratogenic effects and showed no evidence of increased pre-natal susceptibility, adverse eye effects (eye enlargement) were noted in post-natal rat pups older than 14 days in multiple studies (the 2-generation reproduction and 1-generation supplemental studies) and the developmental neurotoxicity (DNT) study reported eye effects appearing in some offspring between lactation days 14 and 42, even though exposure stopped at lactation day 21, indicating a possible delay (a latent response) from the time of last exposure to onset of bupthalmos. These eye 
                    ( print page 47061)
                    effects did not occur in adult rats. Since the iris and chamber angle are differentiating and specializing into definite structures during post-natal days 5-20, neonatal rats appear to have an increased susceptibility to flubendiamide exposure as compared to adults. The DNT study also reported that pre-mating exposures are not required to elicit the eye effect in pups. In addition to the reported eye effects in the DNT study, there was also a balano-preputial separation (separation of the prepuce (foreskin) from the glans penis (balanus)) delay. While these effects are considered adverse, they are not assumed to be developmental effects from 
                    *in utero*
                     exposure. Even though the delay in balanopreputial separation may be a result of post-natal exposure (sensitivity of the young), and the effect is adverse, it is considered reversible and not an indication of perinatal sensitivity/susceptibility. Human microsomes have been shown to be capable of approximately 4 times higher hydroxylation rates of flubendiamide as compared to female mouse microsomes and may be able to efficiently metabolize and excrete flubendiamide, preventing accumulation of the parent compound. It remains unclear whether the ability to metabolize and clear the parent compound is the only requirement to avoid ocular toxicity. Due to the potential concern for increased susceptibility of the human neonate as compared to adults, this perinatal ocular effect is considered in the human health risk assessment for flubendiamide. 3. 
                    *Conclusion*. EPA evaluated the quality of the toxicity and exposure data and, based on these data, has determined that 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 toxicology database for flubendiamide is complete for purposes of this risk assessment and the characterization of potential pre-natal and/or post-natal risks to infants and children. Although susceptibility was identified in the toxicological database (eye effects), the selected regulatory PODs (which are based on clear NOAELs) are protective of these effects; therefore, the human health risk assessment is protective. ii. There are no treatment-related neurotoxic findings in the acute neurotoxicity and DNT studies in rats; although eye effects were observed in the DNT study. As noted in the previous paragraph, the PODs employed in the risk assessment are protective of this effect. iii. There are no residual uncertainties identified in the exposure databases and the exposure assessment is protective. The acute dietary food exposure assessment utilizes tolerance-level residues, the chronic dietary food exposure assessment utilizes average residue levels found in the crop field trials/livestock commodities and both assume 100% of crops with requested uses of flubendiamide are treated. The drinking water assessment generated EDWCs using models and associated modeling parameters which are designed to provide conservative, health protective, high-end estimates of water concentrations. The highest relevant EDWCs were used in the dietary (food and drinking water) exposure assessment. By using these screening-level exposure assessments in the acute and chronic dietary (food and drinking water) assessments, risk is not underestimated for flubendiamide. E. Aggregate Risks and Determination of Safety EPA determines whether acute and chronic pesticide exposures are safe by comparing aggregate exposure estimates to the aPAD and cPAD. The aPAD and cPAD represent the highest safe exposures, taking into account all appropriate SFs. EPA calculates the aPAD and cPAD by dividing the POD by all applicable UFs. For linear cancer risks, EPA calculates the probability of additional cancer cases 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 POD to ensure that the MOE called for by the product of all applicable UFs is not exceeded. For flubendiamide, there is potential exposure from food and drinking water, but not from residential use sites (as there are no proposed residential uses for flubendiamide). Since hazard was identified via the oral route over both the acute and chronic duration, the aggregate risk assessment considers exposures from food and drinking water consumed over the acute and chronic durations. 1. 
                    *Acute risk*. Using the exposure assumptions discussed in this unit for acute exposure, the acute dietary exposure from food and water to flubendiamide will occupy less than 8% of the aPAD for the mostly highly exposed population subgroup, children aged 1-2 years old. 2. 
                    *Chronic risk*. Using the exposure assumptions described in this unit for chronic exposure, EPA has concluded that chronic exposure to flubendiamide from food and water will utilize less than 15% of the cPAD for the mostly highly exposed population subgroup, children aged 1-2 years old. There are no residential uses for flubendiamide. 3. 
                    *Aggregate cancer risk for U.S. population*. Flubendiamide has been classified as “Not Likely to be Carcinogenic to Humans” and is not expected to pose a cancer risk. 4. 
                    *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 flubendiamide residues. IV. Other Considerations A. Analytical Enforcement Methodology Adequate enforcement methodology (LC/MS/MS, Methods 00816/M002 and 00912) is available to enforce the tolerance expression. The method may be requested from: Chief, Analytical Chemistry Branch, Environmental Science Center, 701 Mapes Road, Fort Meade, MD 20755-5350; telephone number: (410) 305-2905; e-mail address: 
                    *residuemethods@epa.gov*. B. International Residue Limits There are currently no established CODEX, Canadian or Mexican maximum residue limits (MRLs) for residues of flubendiamide in or on various crop or livestock commodities. C. Revisions to Petitioned-For Tolerances Based upon review of the data submitted in support of this tolerance petition for flubendiamide and EPA policy, the Agency has revised commodity definitions and/or some of the proposed tolerances. No residue data were submitted to support the proposed uses on okra and popcorn. The available field trial data for fruiting vegetables may be translated to okra, and the submitted data for field corn may also be translated to popcorn. The proposed uses on all types of corn (field, pop and sweet) are identical. Parent residue levels vary based on crop (for edible commodities, residues ranging from 0.018 ppm, corn, field, grain to 6.7 ppm, spinach). Most crops indicated parent residues declined with successive sampling dates and were determined to be available on the surface of plants/RACs. The Agency will allow translation of residue data from trials conducted on rotated barley, sorghum and wheat to support the proposed rotational crop tolerances for the forages, hay and straw of other types of cereal grains and grasses. The Agency 
                    ( print page 47062)
                    will also allow translation of residue data from trials conducted on rotated soybean to support the proposed rotational crop tolerances for the forages, fodder, hay and straw on alfalfa and clover to support the rotational plant-back intervals. Based on the transfer coefficients for livestock tissues and the relatively low dietary burden for swine of 0.02 ppm for flubendiamide, tolerances for hogs are not needed. V. Conclusion Therefore, tolerances are established for residues of the insecticide flubendiamide

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 rule has been exempted from review under Executive Order 12866, this rule is not subject to Executive Order 13211, 
                    *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 tolerances 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 rule. In addition, this 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) (Public Law 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). VII. 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). List of Subjects in 40 CFR Part 180 Environmental protection
