II. Summary of Petitioned-For Tolerance

In the Federal Register of September 8, 2010 (75 FR 54631) (FRL-8843-3), 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 0F7711) by Bayer CropScience, 2 T.W. Alexander Drive P.O. Box 12014, Research Triangle Park, NC 27709. The petition requested that 40 CFR part 180 be amended by establishing tolerances for residues of the penflufen, N-[2-(1,3-dimethylbutyl)phenyl]-5-fluoro-1,3-dimethyl-1 H-pyrazole-4-carboxamide, in or on alfalfa, forage; alfalfa, hay; vegetable, tuberous and corm, subgroup 1C; vegetable, legume, group 6; vegetable, foliage of legume, group 7; grain, cereal, group 15, grain, cereal, forage, fodder and straw, group 16; oilseed, group 19; cotton, gin by-products at 0.01 parts per million (ppm). That notice referenced a summary of the petition prepared by Bayer CropScience, the registrant, which is available in the docket, http://www.regulations.gov. There were no comments received in response to the notice of filing.

Based upon review of the data supporting the petition, EPA has made some minor modifications to some commodity definitions for consistency with EPA naming-conventions for those commodities. The reason for these changes is explained in Unit IV.D.

III. Aggregate Risk Assessment and Determination of Safety

Section 408(b)(2)(A)(i) of FFDCA allows EPA to establish a tolerance (the legal limit for a pesticide chemical residue in or on a food) only if EPA determines that the tolerance is “safe.” Section 408(b)(2)(A)(ii) of FFDCA defines “safe” to mean that “there is a reasonable certainty that no harm will result from aggregate exposure to the pesticide chemical residue, including all anticipated dietary exposures and all other exposures for which there is reliable information.” This includes exposure through drinking water and in residential settings, but does not include occupational exposure. Section 408(b)(2)(C) of FFDCA requires EPA to give special consideration to exposure of infants and children to the pesticide chemical residue in establishing a tolerance and to “ensure that there is a reasonable certainty that no harm will result to infants and children from aggregate exposure to the pesticide chemical residue * * *.”

Consistent with 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 penflufen including exposure resulting from the tolerances established by this action. EPA's assessment of exposures and risks associated with penflufen 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. Penflufen is an alkylamide fungicide belonging to the chemical class of carboxamides. The reported pesticidal mode of action is as an inhibitor of mitochondrial respiration by inhibiting succinate dehydrogenase, an enzyme in the electron transport system.

The liver and thyroid are target organs for penflufen. Increased liver weight, alterations in clinical chemistry parameters relevant to effects on the liver, and an increase in the incidence of hepatocellular hypertrophy were consistent findings across species and duration of exposure (28-day, 90-day, and 1- to 2-year exposure periods). The hepatic total cytochrome P-450 content, and benzoxyresorufin (BROD) and pentoxyresorufin (PROD) enzyme activities, were shown to be increased in rats of both sexes following subchronic oral exposure. Additionally, increased incidence of thyroid follicular cell hypertrophy/hyperplasia was observed across studies and species (no data provided on thyroid hormone levels). The liver and thyroid findings were mostly reversible after a 3-month recovery period in the rat. In the rat and mouse, following 104 week/78 week exposure periods at dose levels up to and/or greater than the limit dose, there was no increase in the incidence of liver or thyroid tumors.

Reproductive toxicity was observed in the 2-generation reproduction study in rats. Delayed sexual maturation was observed in females in both generations, and magnitude of the associated decline in body weight was not considered to be a factor in the delay in sexual maturation. Developmental toxicity was not observed in the rat or rabbit, although the dose levels in both studies were not considered adequate to assess developmental toxicity potential of penflufen. However, there is little concern that new studies would identify a developmental endpoint with a no-observed-adverse-effect-level (NOAEL) lower than the NOAEL selected for risk assessment.

Decreased motor/locomotor activity was observed in both sexes of rats following acute and in female rats following subchronic oral exposure, although neuropathological lesions were not observed in either study.

There are no mutagenicity concerns. Carcinogenicity studies with penflufen found a statistically significant increase in histiocytic sarcomas in male rats; a marginal increase in brain astrocytomas, a fatal tumor, in male rats at the high dose; and ovarian adenomas in female rats at the high dose. Although these three tumors were considered treatment-related, they provided weak evidence of carcinogenicity due to the marginal nature of the tumor responses. There was no evidence of carcinogenicity in male or female mice. Given the weak evidence indicating any potential for carcinogenicity, EPA has determined that quantification of risk using a non-linear approach reference dose (i.e., RfD) will adequately account for all chronic toxicity, including carcinogenicity, which could result from exposure to penflufen. The NOAEL (38 milligram/kilogram/day (mg/kg/day)) used for establishing the Chronic RfD is approximately 10-fold lower than the dose (approximately 300 mg/kg/day) that induced a marginal tumor response. The EPA has determined that the chronic population adjusted dose is protective of all long-term effects, including potential carcinogenicity.

Specific information on the studies received and the nature of the adverse effects caused by penflufen as well as the NOAEL and the lowest-observed-adverse-effect-level (LOAEL) from the toxicity studies can be found at http://www.regulations.gov in document “Penflufen. Human Health Risk Assessment to Support New Uses on Potato (Crop Subgroup 1C), Legume Vegetables (Crop Group 6 and Crop Group 7), Cereal Grains (Crop Group 15 and Crop Group 16), Oilseeds (Crop Group 20), and Alfalfa” in docket ID number EPA-HQ-OPP-2010-0425.

B. Toxicological Points of Departure/Levels of Concern

Once a pesticide's toxicological profile is determined, EPA identifies toxicological points of departure (POD) and levels of concern (LOC) 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 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 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 penflufen used for human risk assessment is shown in the Table of this unit.

C. Exposure Assessment

1. Dietary exposure from food and feed uses. In evaluating dietary exposure to penflufen, EPA considered exposure under the petitioned-for tolerances. EPA assessed dietary exposures from penflufen 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 penflufen. 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 used tolerance-level residues, default dietary exposure evaluation model (DEEM) processing factors for dried potatoes and assumed 100 percent crop treated (PCT) for all commodities.

ii. Chronic exposure. In conducting the chronic dietary exposure assessment EP used the food consumption data from the USDA 1994-1996 and 1998 CSFII. As to residue levels in food, EPA used tolerance-level residues, default DEEM processing factors for dried potatoes and assumed 100 PCT for all commodities.

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 used tolerance-level residues, default DEEM processing factors for dried potatoes and assumed 100 PCT for all commodities.

iii. Cancer. EPA determines whether quantitative cancer exposure and risk assessments are appropriate for a food-use pesticide based on the weight of the evidence from cancer studies and other relevant data. Cancer risk is quantified using a linear or non-linear approach. If sufficient information on the carcinogenic mode of action is available, a threshold or non-linear approach is used based on an earlier non-cancer key event. If carcinogenic mode of action data are not available, or if the mode of action data determines a mutagenic mode of action, a default linear cancer slope factor approach is utilized. Based on the data summarized in Unit III.A., EPA has concluded that a non-linear RfD approach is appropriate for assessing cancer risk to penflufen. Cancer risk was assessed using the same exposure estimates as discussed in Unit III.C.1.ii.

iv. Anticipated residue and PCT information. EPA did not use anticipated residue and/or PCT information in the dietary assessment for penflufen. Tolerance level residues and/or 100 PCT were assumed for all food commodities.

2. Dietary exposure from drinking water. The Agency used screening level water exposure models in the dietary exposure analysis and risk assessment for penflufen in drinking water. These simulation models take into account data on the physical, chemical, and fate/transport characteristics of penflufen. 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 First Index Reservoir Screening Tool (FIRST) and Screening Concentration in Ground Water (SCI-GROW) models, the estimated drinking water concentrations (EDWCs) of penflufen for acute exposures are estimated to be 11.4 parts per billion (ppb) for surface water and 16.6 ppb for ground water. The EDWC of penflufen for chronic exposures for non-cancer assessments are estimated to be 1.8 ppb for surface water and 16.6 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 16.6 ppb was used to assess the contribution to drinking water. For chronic dietary risk assessment, the water concentration of value 16.6 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).

Penflufen is not registered for any specific use patterns that would result in residential exposure.

4. Cumulative effects from substances with a common mechanism of toxicity. Section 408(b)(2)(D)(v) of FFDCA requires that, when considering whether to establish, modify, or revoke a tolerance, the Agency consider “available information” concerning the cumulative effects of a particular pesticide's residues and “other substances that have a common mechanism of toxicity.”

EPA has not found penflufen to share a common mechanism of toxicity with any other substances, and penflufen does not appear to produce a toxic metabolite produced by other substances. For the purposes of this tolerance action, therefore, EPA has assumed that penflufen does not have a common mechanism of toxicity with other substances. For information regarding EPA's efforts to determine which chemicals have a common mechanism of toxicity and to evaluate the cumulative effects of such chemicals, see EPA's Web site at 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 tenfold (10X) margin of safety for infants and children in the case of threshold effects to account for prenatal and postnatal toxicity and the completeness of the database on toxicity and exposure unless EPA determines based on reliable data that a different margin of safety will be safe for infants and children. This additional margin of safety is commonly referred to as the FQPA Safety Factor (SF). In applying this provision, EPA either retains the default value of 10X, or uses a different additional safety factor when reliable data available to EPA support the choice of a different factor.

2. Prenatal and postnatal sensitivity. In the rat multi-generation reproduction study there was slight decrease in litter size, delayed sexual maturation, decreased body weight/gain, decreased brain, spleen, and thymus weights were noted in the offspring. At the same dose level the adults exhibited decreased body weight/gain, alteration in food consumption, decreased thymus weight, and decrease spleen weights. In the rat developmental toxicity study, the maternal findings (decreased body weight gain) at the highest dose tested (HDT) are considered minimal. No adverse effects were observed on the foetuses. In the rabbit developmental toxicity study, the maternal findings (decreased body weight gain) at the HDT are considered minimal. No adverse effects were observed at the HDT.

3. Conclusion. The Agency recommends that the 10X FQPA safety factor for the protection of infants and children, be reduced to 1X. The risk assessments conducted for penflufen were based on the most sensitive endpoints in the toxicity database, and the NOAELs selected for risk assessment are considered protective of potential developmental, neurotoxic, and immunotoxic effects for infants and children. Highly conservative exposure estimates were incorporated into the risk assessment for penflufen. There are no residual uncertainties with regard to pre- and/or postnatal toxicity or neurotoxicity, and exposure; therefore, reduction of the 10X FQPA safety factor for penflufen to 1X is appropriate based on the following findings:

i. The toxicity database for penflufen is complete for consideration of estimated risks for all populations of concern.

ii. Although decreased motor activity was observed following acute oral exposure, no neuropathological lesions were observed and there is little concern for neurotoxicity. There is no need for a developmental neurotoxicity study or additional UFs to account for neurotoxicity.

iii. Although there is some evidence of qualitative sensitivity of the young (delayed sexual maturation and decreased litter size), the effects are well characterized, and there is a clear NOAEL. The dose level where offspring effects were identified in the reproduction study is comparable to the high dose used in the rat developmental toxicity study where no effects were identified in either the maternal or fetal rat. Since minimal/no effects were observed in the developmental toxicity studies following exposure of the maternal animals to dose levels equal to and greater than those tested in the studies used for risk assessment, there is little concern that new studies would identify a developmental endpoint with a NOAEL lower than the NOAELs selected for risk assessment.

iv. There are no residual uncertainties identified in the exposure databases. The dietary food exposure assessments were performed based on 100 PCT and tolerance-level residues. EPA made conservative (protective) assumptions in the ground and surface water modeling used to assess exposure to penflufen in drinking water. These assessments will not underestimate the exposure and risks posed by penflufen.

E. Aggregate Risks and Determination of Safety

EPA determines whether acute and chronic dietary pesticide exposures are safe by comparing aggregate exposure estimates to the acute PAD (aPAD) and chronic PAD (cPAD). For linear cancer risks, EPA calculates the lifetime probability of acquiring cancer given the estimated aggregate exposure. Short-, intermediate-, and chronic-term risks are evaluated by comparing the estimated aggregate food, water, and residential exposure to the appropriate PODs to ensure that an adequate MOE exists.

1. Acute risk. An acute aggregate risk assessment takes into account acute exposure estimates from dietary consumption of food and drinking water. A highly conservative acute dietary exposure assessment demonstrated that penflufen does not pose an unacceptable aggregate risk.

2. Chronic risk. There are no residential uses for penflufen; therefore, the chronic aggregate risk assessment includes exposures from dietary consumption of food and water only. A highly conservative chronic aggregate dietary exposure assessment demonstrated that penflufen does not pose an unacceptable aggregate chronic risk.

3. Short-term risk. There are no residential uses of penflufen; therefore a short-term aggregate risk assessment was not conducted for this chemical.

4. Intermediate-term risk. There are no residential uses of penflufen; therefore an intermediate-term aggregate risk assessment was not conducted for this chemical.

5. Aggregate cancer risk for U.S. population. In a rat carcinogenicity study with penflufen a statistically significant increase in histiocytic sarcomas with a positive trend in male rats only (but in the absence of a dose response and lack of pre-neoplastic lesions) were seen. A marginal increase in brain astrocytomas was also observed in males at the high dose; however, this effect was not dose-related, did not reach statistical significance, and there was no overall trend. In addition, there were no pre-neoplastic lesions, such as glial proliferations, which are a good indicator of chemical tumor induction (i.e., there will be changes in the cells prior to transformation to a neoplasm). The ovarian adenomas observed at the high dose also showed no dose response, no pair-wise significance, no decrease in latency, and there were no pre-neoplastic lesions such as hyperplasia of the epithelial cells of the endometrium. Additionally, there was no evidence of carcinogenicity in male or female mice (at doses that were judged to be adequate to assess the carcinogenic potential), no concern for mutagenicity (in vivo or in vitro) for the parent molecule or the two metabolites, and there were no other lines of evidence (such as structure-activity relationship). Although these three tumors were considered treatment-related, they provided weak evidence of carcinogenicity due to the marginal nature of the tumor responses and the other factors mentioned in this unit. Given the weak evidence indicating any potential for carcinogenicity, EPA has determined that quantification of risk using a non-linear approach (i.e., RfD) will adequately account for all chronic toxicity, including carcinogenicity, which could result from exposure to penflufen. The NOAEL (38 mg/kg/day) used for establishing the chronic RfD is approximately 10-fold lower than the dose (approximately 300 mg/kg/day) that induced a marginal tumor response. The EPA has determined that the chronic population adjusted dose is protective of all long-term effects, including potential carcinogenicity.

6. 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 penflufen residues.

IV. Other Considerations

A. Analytical Enforcement Methodology

Adequate enforcement methodology is available to enforce the tolerance expression. The method involves extraction of samples with acetonitrile/water, cleanup using solid phase extraction, and analysis of penflufen by liquid chromatography/mass spectrometry (LC/MS/MS) (EL-002-P09-03).

B. International Residue Limits

In making its tolerance decisions, EPA seeks to harmonize U.S. tolerances with international standards whenever possible, consistent with U.S. food safety standards and agricultural practices. EPA considers the international maximum residue limits (MRLs) established by the Codex Alimentarius Commission (Codex), as required by FFDCA section 408(b)(4). The Codex Alimentarius is a joint 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 penflufen.

C. Revisions to Petitioned-For Tolerances

Some minor modifications to commodity definitions initially submitted were made to be consistent with the updated EPA naming-conventions for commodities.

V. Conclusion

Therefore, tolerances are established for residues of penflufen, in or on alfalfa, forage; alfalfa, hay; vegetable, tuberous and corm, subgroup 1C; vegetable, legume, group 6; vegetable, foliage of legume, group 7; grain, cereal, group 15, grain, cereal, forage, fodder and straw, group 16; oilseed, group 19; cotton, gin by-products at 0.01 ppm.

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 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).

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).
