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 E:\FR\FM\13AUR1.SGM 13AUR1 Federal Register / Vol. 73, No. 157 / Wednesday, August 13, 2008 / Rules and Regulations hsrobinson on PROD1PC76 with RULES 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 VerDate Aug<31>2005 15:55 Aug 12, 2008 Jkt 214001 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 intermediateterm dermal risks were also based on liver and thyroid effects as well as blood effects. Short-term and intermediateterm 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-adverseeffect-level (NOAEL) and the lowestobserved-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 https:// www.regulations.gov.

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 PO 00000 Frm 00033 Fmt 4700 Sfmt 4700 47059 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 https://www.epa.gov/ pesticides/factsheets/riskassess.htm. A summary of the toxicological endpoints for flubendiamide used for human risk assessment 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 https:// www.regulations.gov.

Dietary exposure from food and feed uses. In evaluating dietary exposure to flubendiamide, EPA considered exposure under the E:\FR\FM\13AUR1.SGM 13AUR1 hsrobinson on PROD1PC76 with RULES 47060 Federal Register / Vol. 73, No. 157 / Wednesday, August 13, 2008 / Rules and Regulations 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, tolerancelevel 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 experimentallydetermined 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 VerDate Aug<31>2005 15:55 Aug 12, 2008 Jkt 214001 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 https://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 nonoccupational, 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 PO 00000 Frm 00034 Fmt 4700 Sfmt 4700 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 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 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 E:\FR\FM\13AUR1.SGM 13AUR1 hsrobinson on PROD1PC76 with RULES Federal Register / Vol. 73, No. 157 / Wednesday, August 13, 2008 / Rules and Regulations 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 balanopreputial 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. VerDate Aug<31>2005 15:55 Aug 12, 2008 Jkt 214001 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 screeninglevel 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. Shortterm, intermediate-term and chronicterm 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 PO 00000 Frm 00035 Fmt 4700 Sfmt 4700 47061 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 E:\FR\FM\13AUR1.SGM 13AUR1 47062 Federal Register / Vol. 73, No. 157 / Wednesday, August 13, 2008 / Rules and Regulations 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. hsrobinson on PROD1PC76 with RULES V. Conclusion Therefore, tolerances are established forresidues of the insecticide flubendiamide per se, N2-[1,1-Dimethyl2-(methylsulfonyl)ethyl-3-iodo-N1-[2methyl-4-[1,2,2,2-tetrafluoro-1(trifluoromethyl)ethyl]phenyl]-1,2benzenedicarboxamide. VI. 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, VerDate Aug<31>2005 15:55 Aug 12, 2008 Jkt 214001 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).

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

[[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 https://

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 https://
www.epa.gov/pesticides/factsheets/riskassess.htm.

human risk assessment can be found in the document entitled,

C. Exposure Assessment

    1. Dietary exposure from food and feed uses. In evaluating dietary 
exposure to flubendiamide, EPA considered exposure under the

[[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-
FCID\TM\, 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-FCID\TM\, 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 https://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 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 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

[[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

[[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 forresidues of the 
insecticide flubendiamide per se, N2-[1,1-Dimethyl-2-
(methylsulfonyl)ethyl-3-iodo-N1-[2-methyl-4-[1,2,2,2-
tetrafluoro-1-(trifluoromethyl)ethyl]phenyl]-1,2-benzenedicarboxamide.

VI. 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).
