II. Background and Statutory Findings
In the Federal Register of January 4, 2006 (71 FR 340) (FRL-7750-6), EPA issued a notice pursuant to section 408(d)(3) of FFDCA, 21 U.S.C. 346a(d)(3), announcing the filing of pesticide petition (PP 4F6892) by Bayer Crop Science, P.O. Box 12014, 2T.W. Alexander Drive, Research Triangle Park, NC 27709. The petition requested that 40 CFR 180.555 be amended by establishing a tolerance for combined residues of the fungicide trifloxystrobin (benzeneacetic acid, (E, E)-α-(methoxyimino)-2-[[[[1-[3-(trifluoromethyl) phenyl]ethylidene]amino]oxy]methyl]-, methylester) and the free form of its acid metabolite CGA-321113 ((E, E)-methoxyimino-[2-[1-(3-trifluoromethylphenyl)- ethylideneaminooxymethyl]-phenyl]acetic acid), (PP 4F6892) in or on corn, sweet, kernel plus cob with husks removed at 0.04 ppm, corn, sweet, forage at 0.6 ppm, corn, sweet, stover at 0.25 ppm, and corn, sweet, cannery waste at 0.6 ppm. That notice included a summary of the petition prepared by Bayer Crop Science, the registrant. There were no comments received in response to the notice of filing.
In the Federal Register of January 18, 2006 (71 FR 2929) (FRL-7756-9), EPA issued a notice pursuant to section 408(d)(3) of FFDCA, 21 U.S.C. 346a(d)(3), announcing the filing of pesticide petition (PP 3E6769) by the Interregional Research Project Number 4 (IR-4), 681 U. S. Highway #1 South, North Brunswick, NJ 08902-3390. The petition requested that 40 CFR 180.555 be amended by establishing a tolerance for residues of the fungicide trifloxystrobin, in or on the following raw agricultural commodities: barley, grain at 0.05 parts per million (ppm); barley, hay at 0.3 ppm; barley, straw at 5.0 ppm; oat, forage at 0.3 ppm; oat, grain at 0.05 ppm; oat, hay at 0.3 ppm; and oat, straw at 5.0 ppm. That notice included a summary of the petition prepared by IR-4. There were no comments received on the notice of filing.
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. . . .”
III. Aggregate Risk Assessment and Determination of Safety
Consistent with 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, consistent with section 408(b)(2) of FFDCA, for a tolerance for combined residues of trifloxystrobin and CGA-321113 (PP 4F6892) in or on corn, sweet, kernel plus cob with husks removed at 0.04 ppm, corn, sweet, forage at 0.6 ppm, corn, sweet, stover at 0.25 ppm, and corn, sweet, cannery waste at 0.6 ppm; (PP 3E6769) oat, forage at 0.3 ppm, oat, grain at 0.05 ppm, oat, hay at 0.3 ppm, oat, straw at 5.0 ppm, barley, grain at 0.05 ppm, barley, hay at 0.3 ppm, barley, straw at 5.0 ppm. EPA's assessment of exposures and risks associated with establishing the tolerance 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 Start Printed Page 15599sensitivities of major identifiable subgroups of consumers, including infants and children. Specific information on the studies received and the nature of the toxic effects caused by trifloxystrobin and CGA-321113 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 Federal Register of May 22, 2002 (67 FR 35915)(FRL-7178-6).
B. Toxicological Endpoints
For hazards that have a threshold below which there is no appreciable risk, the dose at which no adverse effects are observed (the NOAEL) from the toxicology study identified as appropriate for use in risk assessment is used to estimate the toxicological level of concern (LOC). However, the lowest dose at which adverse effects of concern are identified (the LOAEL) is sometimes used for risk assessment if no NOAEL was achieved in the toxicology study selected. An uncertainty factor (UF) is applied to reflect 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.
The linear default risk methodology (Q*) is the primary method currently used by the Agency to quantify non-threshold hazards such as cancer. The Q* approach assumes that any amount of exposure will lead to some degree of cancer risk, estimates risk in terms of the probability of occurrence of additional cancer cases.
A summary of the toxicological endpoints for trifloxystrobin and CGA-321113 used for human risk assessment is shown in Table 1 of this unit:
|Exposure Scenario||Dose Used in Risk Assessment, UF||Special FQPA SF and Level of Concern for Risk Assessment||Study and Toxicological Effects|
|Acute Dietary (females 13-49 only)||NOAEL = 250 mg/kg/day UF = 100 Acute RfD = 2.5 mg/kg/day||FQPA SF = 1X aPAD = aRfD FQPA SF = 2.5 mg/kg/day||Developmental Toxicity-Rat LOAEL = 500 mg/kg/day, based upon increased fetal skeletal anomalies|
|Acute Dietary General Population including infants and children||There were no appropriate toxicological effects attributable to a single exposure (dose) observed in oral toxicity studies including maternal effects in developmental studies in rats and rabbits. Therefore, a dose and endpoint were not identified for this risk assessment.|

C. Exposure Assessment
1. Dietary exposure from food and feed uses. Tolerances have been established (40 CFR 180.555) for the combined residues of trifloxystrobin and CGA-321113, in or on a variety of raw agricultural commodities. Risk assessments were conducted by EPA to assess dietary exposures from trifloxystrobin and CGA-321113 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 in the toxicological studies for trifloxystrobin and CGA-321113 applicable only to Females 13-49 years old. In conducting the acute dietary exposure assessment EPA used the Dietary Exposure Evaluation Model software with the Food Commodity Intake Database (DEEM-FCIDTM), which incorporates food consumption data as reported by respondents in the USDA 1994-1996 and 1998 Nationwide Continuing Surveys of Food Intake by Individuals (CSFII), and accumulated exposure to the chemical for each commodity. The following assumptions were made for the acute exposure assessments: One hundred percent of proposed and registered crops are assumed treated with trifloxystrobin (100% CT) and tolerance-level residues were used in the analysis. The acute dietary endpoint (increased fetal incidence of fused sternebrae) is only applicable to the population subgroup females 13-49 years old. An acute dietary endpoint for the general population including infants and children was not identified. The highest estimate for acute drinking water exposure, 92 ppb, was used in the analysis.
ii. Chronic exposure. In conducting the chronic dietary exposure assessment EPA used the DEEM-FCIDTM, which incorporates food consumption data as reported by respondents in the USDA 1994-1996 and 1998 CSFII, and accumulated exposure to the chemical for each commodity. The following assumptions were made for the chronic exposure assessments: One hundred percent of proposed and registered crops are assumed treated with trifloxystrobin (100% CT) and tolerance-level residues were used in the analysis. The chronic dietary endpoint applies to all population subgroups including infants and children. The highest estimate for chronic drinking water exposure, 140 ppb, was used in the analysis.
iii. Cancer. EPA determined that trifloxystrobin should be classified as a “Not Likely Human Carcinogen.” Due to the classification, no cancer exposure assessment was performed.
2. Dietary exposure from drinking water. Based on the FIRST, and Screening Concentrations in Groundwater (SCI-GROW) models, the estimated environmental concentrations (EECs) of trifloxystrobin and CGA-321113 for acute exposures are estimated to be 92 parts per billion (ppb) for surface water and 34 ppb for ground water. The EECs for chronic exposures are estimated to be 50 ppb for surface water and 3.4 ppb for ground 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).
Trifloxystrobin is currently registered for use on the following residential non-dietary sites: Turfgrass and ornamentals. The risk assessment was conducted using the following residential exposure assumptions: There is potential for dermal (adults and children) and incidental oral exposure (children only) during postapplication activities. The following postapplication exposure scenarios resulting from lawn treatment were assessed:
a. Dermal exposure from pesticide residues on lawns,
b. Incidental non-dietary ingestion of pesticide residues on lawns from hand-to-mouth transfer,
c. Incidental non-dietary ingestion of residues from object-to-mouth activities (pesticide-treated turfgrass), and
d. Incidental non-dietary ingestion of soil from pesticide-treated residential areas. Postapplication exposures from various activities following lawn treatment are considered to be the most common and significant in residential settings. The exposure via incidental non-dietary ingestion involving other plant material may occur but is considered negligible.
4. Cumulative effects from substances with a common mechanism of toxicity. Section 408(b)(2)(D)(v) of the 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.”
Unlike other pesticides for which EPA has followed a cumulative risk approach based on a common mechanism of toxicity, EPA has not made a common mechanism of toxicity finding as to trifloxystrobin and any other substances and trifloxystrobin does not appear to produce a toxic metabolite produced by other substances. For the purposes of this tolerance action, therefore, EPA has not assumed that trifloxystrobin has 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 the policy statements released by EPA's Office of Pesticide Programs concerning common mechanism determinations and procedures for cumulating effects from substances found to have a common mechanism on EPA's website at http://www.epa.gov/pesticides/cumulative/.
D. Safety Factor for Infants and Children
1. In general. Section 408 of FFDCA provides that EPA shall apply an additional tenfold 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 data base on toxicity and exposure unless EPA Start Printed Page 15601determines based on reliable data that a different margin of safety will be safe for infants and children. Margins of safety are incorporated into EPA risk assessments either directly through use of a MOE analysis or through using uncertainty (safety) factors in calculating a dose level that poses no appreciable risk to humans. In applying this provision, EPA either retains the default value of 10X when reliable data do not support the choice of a different factor, or, if reliable data are available, EPA uses a different additional safety factor (SF) value based on the use of traditional uncertainty factors and/or special FQPA safety factors, as appropriate.
2. Prenatal and postnatal sensitivity. The EPA concluded that the toxicology database was complete for Food Quality Protection Act (FQPA) purposes and that there are no residual uncertainties for prenatal/postnatal toxicity.
3. Conclusion. EPA determined that the 10X SF to protect infants and children should be reduced to 1X. The FQPA, SF is reduced because:
i. There is a complete toxicity data base for trifloxystrobin.
ii. There is no indication of increased susceptibility of rat or rabbits to trifloxystrobin. In the developmental and reproduction toxicity studies, effects in the fetuses/offspring were observed only at or above treatment levels which resulted in evidence of parental toxicity;
iii. EPA determined that a developmental neurotoxicity study in rats is not required;
iv. Although an acute neurotoxicity study is required (the submitted study was unacceptable), the lack of an acute neurotoxicity study does not impact EPA's ability to make an FQPA safety factor decision because upgrading the study would not result in a lower NOAEL than what is present for the acute RfD;
v. The acute and chronic dietary food exposure assessments utilize existing and proposed tolerance level residues and 100% crop treated information for all commodities. By using these screening-level assessments, actual exposures/risks will not be underestimated;
vi. The dietary drinking water assessment utilizes water concentration values generated by model and associated modeling parameters, which are designed to provide conservative, health protective, high-end estimates of water concentrations, which are not likely to be exceeded; and
vii. The residential postapplication assessment is based upon the residential SOPs. The assessment is based upon surrogate study data. These data are reliable and are not expected to underestimate risk to adults or children. The residential SOPs are based upon reasonable “worst-case” assumptions and are not expected to underestimate risk.
E. Aggregate Risks and Determination of Safety
1. Acute risk. The aggregate acute risk estimates include exposure to residues of trifloxystrobin in food and water, and does not include dermal, inhalation or incidental oral exposure. Since the dietary exposure assessment already includes the highest acute exposure from the drinking water modeling data, no further calculations are necessary. The acute risk estimate for females 13-49 years, resulting from aggregate exposure to trifloxystrobin in food and drinking water is below Health Effects Division (HED)'s level of concern. The food and water exposure estimates for females 13-49 yrs old is <1% aPAD.
2. Chronic risk. The aggregate chronic risk assessment takes into account average exposure estimates from dietary consumption of trifloxystrobin (food and drinking water) and residential uses. Since the exposure from turf is considered short-term, the aggregate chronic assessment included food and drinking water only. Since the dietary exposure assessment already includes the highest chronic exposure from the drinking water modeling data, no further calculations are necessary. The general U.S. population and all population subgroups have exposure and risk estimates which are below EPA's level of concern (i.e., the percentages of the chronic population adjusted doses (cPADs) are all below 100%). The exposure to the U.S. population was 21% cPAD and the most highly exposed subgroup, children 1-2 yrs old, at 62% cPAD. Therefore, chronic risk estimates resulting from aggregate exposure to trifloxystrobin in food and drinking water are below EPA's level of concern from all population subgroups.
3. Short-term risk. The short-term aggregate risk assessment estimates risks likely to result from 1- to 30-day exposure to trifloxystrobin residues from food, drinking water, and residential pesticide uses. High-end estimates of residential exposure are used in the short-term assessment, while average values are used for food and drinking water exposure (i.e. chronic exposures).
Different endpoints were identified by EPA for short-term incidental oral and dermal risk assessment (the basis for the oral endpoint is reduced pup body weights and the dermal endpoint is based on increases in liver and kidney weights). Therefore, it is not possible to combine dietary/incidental oral exposure with dermal exposure.
A short-term risk assessment was not required for adults, because no incidental oral exposure is expected for adults. A short-term risk assessment is required for infants and children because there are residential postapplication oral exposure scenarios. Toddlers' incidental oral exposure is assumed to include hand-to-mouth exposure, object-to-mouth exposure and exposure through incidental ingestion of soil. Table 2 summarizes short-term aggregate risk from incidental oral and dietary food and water sources for children.
|NOAEL mg/kg/day||LOC MOE1||Average Food + Water Exposure mg/kg/day||Residential Exposure2 mg/kg/day||Aggregate MOE (food and residential)3|
|Youth (13-19 years)||N/A||N/A||0.005867||N/A||650|
|All Infants (>1 year)||N/A||N/A||0.021883||0.00642||130|
|Children (1-2 years)||N/A||N/A||0.023429||0.00642||130|
|Start Printed Page 15602|
|Females (13-49 years old)||N/A||N/A||0.006312||N/A||600|
|1 The level of concern (LOC) MOE is 100, based on inter- and intra-species safety factors totaling 100.|
|2 Residential Exposure = Incidental Oral exposure from all possible sources. No residential oral exposure is expected for adults.|
|3 Aggregate MOE = NOAEL (3.8 mg/kg/day) ÷ (Avg Food Exposure + Residential Exposure).|
As shown above in Table 2, the aggregate short-term MOE for all infants less than 1 yr old and children 1-2 years old at 130 does not exceed EPA's level of concern, a MOE of 100. It should be noted that the maximum surface water concentration, which is included in the average food and water exposure, results from the use on rice, is considered to be an overestimate of the true value found in the environment due to the intricacies of the drinking water model, and should be viewed as very conservative. Further, EPA considers the turfgrass estimate (50 ppb) to be a more realistic estimate of drinking water residues. EPA does not consider short-term aggregate risk for children to be a concern.
4. Intermediate-term risk. An intermediate-term aggregate risk (1 to 6 months of exposure to trifloxystrobin residues from food, drinking water, and residential pesticide uses) is not expected to occur based on the short soil half-life (about 2 days).
5. Aggregate cancer risk for U.S. population. Trifloxystrobin is not expected to pose a cancer risk.
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, and to infants and children from aggregate exposure to trifloxystrobin residues.
IV. Other Considerations
A. Analytical Enforcement Methodology
Adequate enforcement methodology (gas chromatography method using nitrogen/phosphorus detector) is available to enforce the tolerance expression. The method may be requested from: Chief, Analytical Chemistry Branch, Environmental Science Center, 701 Mapes Rd., Ft. Meade, MD 20755-5350; telephone number: (410) 305-2905; e-mail address: email@example.com.
B. International Residue Limits
The Codex Alimentarius Comission has established maximum residue limits (MRLs) for trifloxystrobin in/on corn and barley grain. The U.S. tolerances are not compatible with the Codex MRLs because the U.S. and Codex tolerance expressions are different. The current U.S. tolerance for corn grain (i.e., field corn) is set at 0.05 ppm, while we are proposing a tolerance of 0.04 ppm for sweet corn. Both of these U.S. tolerances are not compatible with the Codex MRL for maize, because the U.S. and Codex tolerance expressions are different. The U.S. and Codex residue definitions differ in that the U.S. tolerance includes the acid metabolite whereas the Codex does not. Although non-quantifiable residues of each compound were observed in both the North American and European field trials, the U.S. tolerance on sweet corn (0.04 ppm) is being established at twice the level of Codex MRL for maize (0.02 ppm). For barley, the European GAP use rate is almost four times the U.S. use rate, which partly explains the much higher Codex MRL (0.5 ppm).
The Canadian MRLs have been established for wheat, oats and barley at 0.05 ppm. The U.S. tolerances for barley and oats are being established at 0.05 ppm and the wheat tolerance has already been established at 0.05 ppm. Harmonization is thus not an issue.
Therefore, the tolerance is established for combined residues of trifloxystrobin and CGA-321113, (PP 4F6892) in or on corn, sweet, kernel plus cob with husks removed at 0.04 ppm, corn, sweet, forage at 0.6 ppm, corn, sweet, stover at 0.25 ppm, and corn, sweet, cannery waste at 0.6 ppm; (PP 3E6769) oat, forage at 0.3 ppm, oat, grain at 0.05 ppm, oat, hay at 0.3 ppm, oat, straw at 5.0 ppm, barley, grain at 0.05 ppm, barley, hay at 0.3 ppm, barley, straw at 5.0 ppm.
VI. Objections and Hearing Requests
Under section 408(g) of FFDCA, as amended by FQPA, any person may file an objection to any aspect of this regulation and may also request a hearing on those objections. The EPA procedural regulations which govern the submission of objections and requests for hearings appear in 40 CFR part 178. Although the procedures in those regulations require some modification to reflect the amendments made to FFDCA by FQPA, EPA will continue to use those procedures, with appropriate adjustments, until the necessary modifications can be made. The new section 408(g) of FFDCA provides essentially the same process for persons to “object” to a regulation for an exemption from the requirement of a tolerance issued by EPA under new section 408(d) of FFDCA, as was provided in the old sections 408 and 409 of FFDCA. However, the period for filing objections is now 60 days, rather than 30 days.

In person or by courier, bring a copy to the location of the PIRIB described in ADDRESSES. Please use an ASCII file format and avoid the use of special characters and any form of encryption. Copies of electronic objections and hearing requests will also be accepted on disks in WordPerfect 6.1/8.0 or ASCII file format. Do not include any CBI in your electronic copy. You may also submit an electronic copy of your request at many Federal Depository Libraries.
B. When Will the Agency Grant a Request for a Hearing?
A request for a hearing will be granted if the Administrator determines that the material submitted shows the following: There is a genuine and substantial issue of fact; there is a reasonable possibility that available evidence identified by the requestor would, if established resolve one or more of such issues in favor of the requestor, taking into account uncontested claims or facts to the contrary; and resolution of the factual issue(s) in the manner sought by the requestor would be adequate to justify the action requested (40 CFR 178.32).
VII. Statutory and Executive Order Reviews
This final rule establishes a tolerance 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 due to its lack of significance, 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). 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., or 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). 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); or OMB review or any Agency action under Executive Order 13045, entitled Protection of Children from Environmental Health Risks and Safety Risks (62 FR 19885, April 23, 1997). 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). 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. In addition, the Agency has determined that this action will not have a substantial direct effect on States, on the relationship between the national government and the States, or on the distribution of power and responsibilities among the various levels of government, as specified in Executive Order 13132, entitled Federalism (64 FR 43255, August 10, 1999). Executive Order 13132 requires EPA to develop an accountable process to ensure “meaningful and timely input by State and local officials in the development of regulatory policies that have federalism implications.” “Policies that have federalism implications” is defined in the Executive Order to include regulations that have “substantial direct effects on the States, on the relationship between the national government and the States, or on the distribution of power and responsibilities among the various levels of government.” This final rule directly regulates growers, food processors, food handlers and food retailers, not States. This action does not alter the relationships or distribution of power and responsibilities established by Congress in the preemption provisions of section 408(n)(4) of FFDCA. For these same reasons, the Agency has determined that this rule does not have any “tribal implications” as described in Executive Order 13175, entitled Consultation and Coordination with Indian Tribal Governments (65 FR 67249, November 6, 2000). Executive Order 13175, requires EPA to develop an accountable process to ensure “meaningful and timely input by tribal officials in the development of regulatory policies that have tribal implications.” “Policies that have tribal implications” is defined in the Executive Order to include regulations that have “substantial direct effects on one or more Indian tribes, on the relationship between the Federal Government and the Indian tribes, or on the distribution of power and responsibilities between the Federal Government and Indian tribes.” This rule will not have substantial direct effects on tribal governments, on the relationship between the Federal Government and Indian tribes, or on the distribution of power and responsibilities between the Federal Government and Indian tribes, as specified in Executive Order 13175. Thus, Executive Order 13175 does not apply to this rule.
VIII. Congressional Review Act
The Congressional Review Act, 5 U.S.C. 801 et seq., as added by the Small Business Regulatory Enforcement Fairness Act of 1996, generally provides that before a rule may take effect, the agency promulgating the rule must submit a rule report, which includes a copy of the rule, 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).Start List of Subjects
