II. Summary of Petitioned-for Tolerance

ack to Top

In the Federal Register of December 17, 2014 (79 FR 75107) (FRL-9918-90), EPA issued a document pursuant to FFDCA section 408(d)(3), 21 U.S.C. 346a(d)(3), announcing the filing of a pesticide petition (PP 4F8281) by BASF Corporation, P.O. Box 13528, Research Triangle Park, North Carolina, 27709. The petition requested that 40 CFR 180.493 be amended by establishing tolerances for residues of the fungicide, dimethomorph in or on strawberry at 1.0 parts per million (ppm) and removing the established tolerances forlettuce, head and lettuce, leaf at 10 ppm. That document referenced a summary of the petition prepared by BASF, the registrant, which is available in the docket, http://www.regulations.gov. No comments were received in response to the notice of filing.

ased upon review of the data supporting the petition, EPA has revised the tolerance for residues of dimethomorph in or strawberry to 0.90 ppm and is correcting the CAS name of dimethomorph in 40 CFR 180.493(a), 40 CFR 180.493(c), and 40 CFR 180.493(d) to the following introductory tolerance expression text: 40 CFR 180.493(a): Tolerances are established for residues of the fungicide dimethomorph, 4-[3-(4-chlorophenyl)-3-(3,4-dimethoxyphenyl)-1-oxo-2-propen-1-yl]morpholine, including its metabolites and degradates, in or on the commodities in the following table. Compliance with the tolerance levels specified in the following table is to be determined by measuring only dimethomorph in or on the commodity. 40 CFR 180.493(c): Tolerances with regional registrations are established for residues of the fungicide dimethomorph, 4-[3-(4-chlorophenyl)-3-(3,4-dimethoxyphenyl)-1-oxo-2-propen-1-yl]morpholine, including its metabolites and degradates, in or on the commodities in the following table. Compliance with the tolerance levels specified in the following table is to be determined by measuring only dimethomorph in or on the commodity. 40 CFR 180.493(d): Tolerances are established for the indirect or inadvertent residues of the fungicide dimethomorph, 4-[3-(4-chlorophenyl)-3-(3,4-dimethoxyphenyl)-1-oxo-2-propen-1-yl]morpholine, including its metabolites and degradates, in or on the commodities in the following table. Compliance with the tolerance levels specified in the following table is to be determined by measuring only dimethomorph in or on the commodity.

The reason for these changes are explained in Unit IV.C.

III. Aggregate Risk Assessment and Determination of Safety

ack to Top

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

Consistent with FFDCA section 408(b)(2)(D), and the factors specified in FFDCA section 408(b)(2)(D), EPA has reviewed the available scientific data and other relevant information in support of this action. EPA has sufficient data to assess the hazards of and to make a determination on aggregate exposure for dimethomorph including exposure resulting from the tolerances established by this action. EPA‘s assessment of exposures and risks associated with dimethomorph follows.

A. Toxicological Profile

EPA has evaluated the available toxicity data and considered its validity, completeness, and reliability as well as the relationship of the results of the studies to human risk. EPA has also considered available information concerning the variability of the sensitivities of major identifiable subgroups of consumers, including infants and children. The target organ for dimethomorph is the liver in rats and dogs. No biologically significant effect was observed in the rat subchronic oral toxicity study while decreased body weight and increased incidence of arteritis in male rats and decreased body weights and increased incidence of “ground-glass” foci in livers of female rats were observed in the rat chronic toxicity study. In the dog subchronic oral toxicity study, decreased absolute and relative prostate weights, and slight liver effects were observed. No toxicity was observed at the limit dose in the rat 28-day dermal toxicity study. The developmental toxicity studies showed no increased sensitivity to offspring of either rats or rabbits as demonstrated by the no-observed-adverse-effect-levels (NOAELs) equal to or higher than those producing toxicity in the maternal animals. Likewise, in the 2-generation reproduction study, there was no toxicity to the offspring at any dose lower than that causing parental toxicity. There is no evidence that dimethomorph is a developmental, or reproductive toxicant, and it is not neurotoxic or immunotoxic.

The Agency classified dimethomorph as “not likely to be carcinogenic to humans” based upon lack of evidence of carcinogenicity in rats and mice and no evidence of mutagenicity. A quantitative cancer risk assessment is not necessary. Dimethomorph has low acute toxicity by the oral, dermal, or inhalation route of exposure (Toxicity Category III or IV). It is not an eye or skin irritant, and is not a skin sensitizer.

ecific information on the studies received and the nature of the adverse effects caused by dimethomorph 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 the document titled “Dimethomorph: Human Health Risk Assessment to Support Establishment of a Permanent Tolerance for Residues in/on Strawberry” at pages 29-32 in docket ID number EPA-HQ-OPP-2014-0531.

. Toxicological Points of Departure/Levels of Concern

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

A summary of the toxicological endpoints for dimethomorph used for human risk assessment is shown in Table 1 of this unit.

Cancer (Oral, dermal, inhalation)Classification: This chemical is classified as “not likely” to be a human carcinogen.

C. Exposure Assessment

1. Dietary exposure from food and feed uses. In evaluating dietary exposure to dimethomorph, EPA considered exposure under the petitioned-for tolerances as well as all existing dimethomorph tolerances in 40 CFR 180.493. EPA assessed dietary exposures from dimethomorph 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 dimethomorph. In estimating acute dietary exposure, EPA used food consumption information from the United States Department of Agriculture (USDA) National Health and Nutrition Examination Survey, What We Eat in America (NHANES/WEIA) 2003-2008. The acute analysis assumed 100% crop treated (CT), Dietary Exposure evaluation Model software with the Food Commodity Intake Database (DEEM-FCID) Version 3.16 default processing factors, and tolerance-level residues for all foods. Drinking water was incorporated directly into the dietary assessment using the surface water concentration and the FIRST (Food Quality Protection Act (FQPA) Index Reservoir Screening Tool) model.

ii. Chronic exposure. In conducting the chronic dietary exposure assessment EPA used the food consumption data from the USDA NHANES/WEIA 2003-2008. The chronic analysis assumed 100% CT, DEEM-FCID Version 3.16 default processing factors, and tolerance-level residues for all foods. Drinking water was incorporated directly into the dietary assessment using the surface water concentration and the FIRST model.

iii. Cancer. based on the data summarized in Unit III.A., EPA has concluded that dimethomorph does not pose a cancer risk to humans. Therefore, a dietary exposure assessment for the purpose of assessing cancer risk is unnecessary.

iv. Anticipated residue and percent crop treated (PCT) information. EPA did not use any anticipated residue or PCT information in the dietary assessment for dimethomorph.

2. Dietary exposure from drinking water. The Agency used screening level water exposure models in the dietary exposure analysis and risk assessment for dimethomorph in drinking water. These simulation models take into account data on the physical, chemical, and fate/transport characteristics of dimethomorph. 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.

ased on FIRST model for surface water and Pesticide Root Zone Model Ground Water (PRZM GW) for ground water, the estimated drinking water concentrations (EDWCs) of dimethomorph for acute exposures for non-cancer assessments are estimated to be 81.1 parts per billion (ppb) for surface water and 20.1 ppb for ground water; and for chronic exposures for non-cancer assessments are estimated to be 24.7 ppb for surface water and 18.8 ppb (post breakthrough avg. ppb) and 14.6 ppb (simulation avg. 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 of 81.1 ppb was used to assess the contribution to drinking water.

For chronic dietary risk assessment, the water concentration of 24.7 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). Dimethomorph 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 dimethomorph to share a common mechanism of toxicity with any other substances, and dimethomorph does not appear to produce a toxic metabolite produced by other substances. For the purposes of this tolerance action, therefore, EPA has assumed that dimethomorph 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. The toxicology data on dimethomorph provides no indication of enhanced sensitivity of infants and children based on the results from rat or rabbit developmental studies as well as a 2-generation rat reproduction study.

3. Conclusion. EPA has determined the 10X FQPA SF be retained for acute dietary exposure scenario for extrapolation of a NOAEL from a LOAEL. For other exposure scenarios, the FQPA SF is reduced to 1x since there is no evidence of increased qualitative or quantitative susceptibility in the young and exposure estimates are unlikely to underestimate risk.

The above decision is based on the following findings:

i. Although the toxicity database of dimethomorph is incomplete because a subchronic inhalation study is not available, the available toxicity database of dimethomorph, including developmental toxicity studies in rats and rabbits, a 2-generation reproduction study in rats, acute and subchronic neurotoxicity study in rats, is adequate to characterize developmental and reproductive effects and to assess the qualitative or quantitative susceptibility in the young.

ii. In an acute neurotoxicity study, functional observational battery (FOB) findings and reduced motor activity were observed at ≥ 250 mg/kg on day 0 only. These findings were considered an impairment of the overall condition of the animals following a single gavage dose, rather than a direct neurotoxic effect of dimethomorph based on the absence of any neurohistopathological changes in the treated animals and the transient nature of the observed FOB and neurobehavioral assessments. In support of this conclusion, no neurotoxic effects were observed in rats fed dimethomorph up to the highest dose tested at 2,400 ppm (178/204 mg/kg/day for males/females, respectively) in a 90-day neurotoxicity study. Additionally, the toxicology database does not reveal evidence of neurotoxic clinical signs, changes in brain weight, or histopathology of the nervous system in any study with dimethomorph.

iii. There is no evidence that dimethomorph results in increased susceptibility in in utero rats or rabbits in the prenatal developmental studies or in young rats in the 2-generation reproduction study.

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

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. Using the exposure assumptions discussed in this unit for acute exposure, the acute dietary exposure from food and water to dimethomorph will occupy 39% of the aPAD for children 3 to 5 years of age,the population group receiving the greatest exposure.

2. Chronic risk. Using the exposure assumptions described in this unit for chronic exposure, EPA has concluded that chronic exposure to dimethomorph from food and water will utilize 26% of the cPAD for children 1 to 2 years of age, the population group receiving the greatest exposure. There are no residential uses for dimethomorph.

3. Short-term risk. Short-term aggregate exposure takes into account short-term residential exposure plus chronic exposure to food and water (considered to be a background exposure level).

A short-term adverse effect was identified; however, dimethomorph is not registered for any use patterns that would result in short-term residential exposure. Short-term risk is assessed based on short-term residential exposure plus chronic dietary exposure. Because there is no short-term residential exposure and chronic dietary exposure has already been assessed under the appropriately protective cPAD (which is at least as protective as the POD used to assess short-term risk), no further assessment of short-term risk is necessary, and EPA relies on the chronic dietary risk assessment for evaluating short-term risk for dimethomorph.

4. Intermediate-term risk. Intermediate-term aggregate exposure takes into account intermediate-term residential exposure plus chronic exposure to food and water (considered to be a background exposure level). An intermediate-term adverse effect was identified; however, dimethomorph is not registered for any use patterns that would result in intermediate-term residential exposure. Intermediate-term risk is assessed based on intermediate-term residential exposure plus chronic dietary exposure. Because there is no intermediate-term residential exposure and chronic dietary exposure has already been assessed under the appropriately protective cPAD (which is at least as protective as the POD used to assess intermediate-term risk), no further assessment of intermediate-term risk is necessary, and EPA relies on the chronic dietary risk assessment for evaluating intermediate-term risk for dimethomorph.

5. Aggregate cancer risk for U.S. population. An aggregate cancer risk was not calculated because dimethomorph was classified as “not likely to be carcinogenic to humans”.

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 dimethomorph residues.

IV. Other Considerations

ack to Top

A. Analytical Enforcement Methodology

Adequate enforcement methodology (high performance liquid chromatography with ultraviolet detection (HPLC/UV) method FAMS 002-04 and Method M 2577, a gas chromatographic (GC) method with nitrogen phosphorus detection (NPD)) are available to enforce the tolerance expression.

. International Residue Limits

In making its tolerance decisions, EPA seeks to harmonize U.S. tolerances with international standards whenever possible, consistent with U.S. food safety standards and agricultural practices. EPA considers the international maximum residue limits (MRLs) established by the Codex Alimentarius Commission (Codex), as required by FFDCA section 408(b)(4). The Codex Alimentarius is a joint United Nations Food and Agriculture Organization/World Health Organization food standards program, and it is recognized as an international food safety standards-setting organization in trade agreements to which the United States is a party. EPA may establish a tolerance that is different from a Codex MRL; however, FFDCA section 408(b)(4) requires that EPA explain the reasons for departing from the Codex level.

The Codex has established MRLs for dimethomorph in or on strawberry at 0.05 ppm. These MRLs are different than the tolerances established for dimethomorph in the United States. EPA is not proposing to harmonize the U.S. tolerance for residues in strawberry with the Codex due to different application rates (U.S. application rate, 219-237 gram active ingredient/hectare, and Codex countries‘ application rate, 150 gram active ingredient/hectare).

C. Revisions to Petitioned-For Tolerances

ASF proposed a tolerance of dimethomorph residues on strawberry at 1.0 ppm. BASF and EPA used the Organization for Economic Cooperation & Development (OECD) spreadsheet calculator and both determined from the data set that a tolerance of 0.90 ppm was the recommended OECD calculator spreadsheet output. However, BASF rounded that value to 1.0 ppm, while EPA‘s policy is to establish the tolerance at the OECD calculator output level without rounding; therefore, EPA is establishing a tolerance on strawberry at 0.90 ppm. EPA established the tolerance for leafy vegetables (except brassica) crop group 4 in the Federal Register on May 4, 2012 under docket ID number EPA-HQ-OPP-2011-0388. In this ruling, the tolerance for vegetable, leafy, except brassica, group 4 was established at 30.0 ppm. According to 40 CFR 180.493, the individual tolerances for lettuce, head and lettuce, leaf, both at 10.0 ppm, were not removed. based upon the previous explanation, EPA is removing the tolerances for lettuce, head at 10.0 ppm and lettuce, leaf at 10.0 ppm.

EPA is correcting the CAS name of dimethomorph in 40 CFR 180.493(a), 40 CFR 180.493(c), and 40 CFR 180.493(d). The CAS name of dimethomorph is currently incorrect (currently is listed as the International Union of Pure and Applied Chemistry (IUPAC) name (E,Z)-4-[3-(4-chlorophenyl)-3-(3,4-dimethoxyphenyl) acryloyl]morpholine, and is being revised to the correct CAS name 4-[3-(4-chlorophenyl)-3-(3,4-dimethoxyphenyl)-1-oxo-2-propen-1-yl]morpholine)).

V. Conclusion

ack to Top

Therefore, EPA is establishing a tolerance for residues of the fungicide, dimethomorph in or on strawberry at 0.90 ppm and removing the established tolerances for lettuce, head and lettuce leaf at 10 ppm. EPA is correcting the CAS name of dimethomorph in 40 CFR 180.493(a), 40 CFR 180.493(c), and 40 CFR 180.493(d) to the following tolerance expressions:

40 CFR 180.493(a): Tolerances are established for residues of the fungicide dimethomorph, 4-[3-(4-chlorophenyl)-3-(3,4-dimethoxyphenyl)-1-oxo-2-propen-1-yl]morpholine, including its metabolites and degradates, in or on the commodities in the following table. Compliance with the tolerance levels specified in the following table is to be determined by measuring only dimethomorph in or on the commodity.

40 CFR 180.493(c): Tolerances with regional registrations are established for residues of the fungicide dimethomorph, 4-[3-(4-chlorophenyl)-3-(3,4-dimethoxyphenyl)-1-oxo-2-propen-1-yl]morpholine, including its metabolites and degradates, in or on the commodities in the following table. Compliance with the tolerance levels specified in the following table is to be determined by measuring only dimethomorph in or on the commodity.

40 CFR 180.493(d): Tolerances are established for the indirect or inadvertent residues of the fungicide dimethomorph, 4-[3-(4-chlorophenyl)-3-(3,4-dimethoxyphenyl)-1-oxo-2-propen-1-yl]morpholine, including its metabolites and degradates, in or on the commodities in the following table. Compliance with the tolerance levels specified in the following table is to be determined by measuring only dimethomorph in or on the commodity.

VI. Statutory and Executive Order Reviews

ack to Top

This action establishes tolerances under FFDCA section 408(d) in response to a petition submitted to the Agency. The Office of Management and Budget (OMB) has exempted these types of actions from review under Executive Order 12866, entitled “Regulatory Planning and Review” (58 FR 51735, October 4, 1993). Because this action has been exempted from review under Executive Order 12866, this action 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 action does not contain any information collections subject to OMB approval under the Paperwork Reduction Act (PRA) (44 U.S.C. 3501 et se.), 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).

ince tolerances and exemptions that are established on the basis of a petition under FFDCA section 408(d), such as the tolerance in this final rule, do not require the issuance of a proposed rule, the requirements of the Regulatory Flexibility Act (RFA) (5 U.S.C. 601 et se.), do not apply.

This action directly regulates growers, food processors, food handlers, and food retailers, not States or tribes, nor does this action alter the relationships or distribution of power and responsibilities established by Congress in the preemption provisions of FFDCA section 408(n)(4). As such, the Agency has determined that this action will not have a substantial direct effect on States or tribal governments, on the relationship between the national government and the States or tribal governments, or on the distribution of power and responsibilities among the various levels of government or between the Federal Government and Indian tribes. Thus, the Agency has determined that Executive Order 13132, entitled “Federalism” (64 FR 43255, August 10, 1999) and Executive Order 13175, entitled “Consultation and Coordination with Indian Tribal Governments” (65 FR 67249, November 9, 2000) do not apply to this action. In addition, this action does not impose any enforceable duty or contain any unfunded mandate as described under Title II of the Unfunded Mandates Reform Act (UMRA) (2 U.S.C. 1501 et se.).

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 (NTTAA) (15 U.S.C. 272 note).
