II. Background and Statutory Findings

-In the Federal Register of April 21, 2006 (71 FR 20667) (FRL-8056-4), EPA issued a notice pursuant to section 408(d)(3) of FFDCA, 21 U.S.C. 346a(d)(3), announcing the filing of pesticide petitions (PP 3E6755; 5E6969; and 5E6970) by the Interregional Research Project #4 (IR-4), 681 U.S. Highway #1 South, North Brunswick, NJ 08902-3390. The petitions requested that 40 CFR 180.588 be amended by establishing tolerances for residues of the fungicide quinoxyfen, (5,7-dichloro-4-(4-fluorophenoxy) quinoline in or on the raw agricultural commodities: eggplant at 1.0 parts per million (ppm) (PP 3E6755); peppers (bell and non-bell) at 1.0 ppm (PP 3E6755); melon subgroup 9A at 0.1 ppm (PP 5E6969); lettuce, head and leaf at 17.0 ppm (PP 5E6970); and strawberry at 0.8 ppm (PP 5E6970). That notice included a summary of the petition prepared by Dow AgroSciences, the registrant. There were no comments received in response to the notice of filing.-

Upon completing review of the current quinoxyfen database, the Agency concluded that the appropriate tolerance levels for quinoxyfen residues in or on pending crops should be established as follow: Lettuce, head at 7.0 ppm; lettuce, leaf at 19 ppm; melon, subgroup 9A at 0.08 ppm; pepper, bell at 0.35 ppm; pepper, non-bell at 1.7 ppm; and strawberry at 0.90 ppm. The Agency concluded that there are insufficient data to establish a tolerance for quinoxyfen residues in or on eggplant, at this time.

-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....”

-EPA performs a number of analyses to determine the risks from aggregate exposure to pesticide residues. For further discussion of the regulatory requirements of section 408 of the FFDCA and a complete description of the risk assessment process, see http://www.epa.gov/​fedrgstr/​EPA-PEST/​1997/​November/​Day-26/​p30948.htm.

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 residues of quinoxyfen on lettuce, head at 7.0 ppm; lettuce, leaf at 19 ppm; melon (subgroup 9A) at 0.08 ppm; pepper, bell at 0.35 ppm; pepper, non-bell at 1.7 ppm; and strawberry at 0.90 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 their 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. Specific information on the studies received and the nature of the toxic effects caused by quinoxyfen 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 September 29, 2003 (68 FR 55858) (FRL-7318-2), under docket ID number EPA-HQ-OPP-2003-0218, to which the reader may refer for additional information.

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 Start Printed Page 50352Q* 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. More information can be found on the general principles EPA uses in risk characterization at http://www.epa.gov/​pesticides/​health/​human.htm.

A summary of the toxicological endpoints for quinoxyfen used for human risk assessment is discussed in Unit III.B. of the final rule published in the Federal Register of September 29, 2003 (68 FR 55858) (FRL-7318-2), under docket ID number EPA-HQ-OPP-2003-0218, to which the reader may refer for additional information.

C. Exposure Assessment

-1. Dietary exposure from food and feed uses. Tolerances have been established (40 CFR 180.588) for the residues of quinoxyfen, in or on a variety of raw agricultural commodities. Permanent tolerances are established for residues of quinoxyfen per se in/on cherry, sweet and cherry, tart at 0.30 ppm; grape at 0.60 ppm; and dried hop cones at 3.0 ppm. In addition, time-limited tolerances are established under Section 18 emergency exemptions for residues of quinoxyfen per se in/on pumpkin; squash, winter; and vegetables, curcubit, subgroup 9A. Risk assessments were conducted by EPA to assess dietary exposures from quinoxyfen 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 one-day or single exposure.

There were no toxic effects attributable to a single dose. Therefore, an endpoint of concern was not identified to quantitate acute-dietary risk to the general population or to the subpopulation females 13-50 years old. As a result, no acute risk is expected from exposure to quinoxyfen.

-ii. Chronic exposure. In conducting the chronic dietary exposure assessment EPA used the Dietary Exposure Evaluation Model software with the Food Commodity Intake Database (DEEM-FCIDTM), Version 2.03, 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 chronic exposure assessments: An unrefined, Tier 1 chronic dietary (food and water) exposure assessment using tolerance-level residues and assuming 100% crops treated for all proposed commodities, and default DEEM Version 7.76 processing factors for all commodities.

-iii. Cancer. Quinoxyfen is classified as “not likely to be carcinogenic to humans,” based on the lack of evidence of carcinogenicity in rat and mice studies. Therefore, an exposure assessment for the purpose of evaluating cancer risk is not needed.

-2. Dietary exposure from drinking water. The Agency lacks sufficient monitoring exposure data to complete a comprehensive dietary exposure analysis and risk assessment for quinoxyfen in drinking water. 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 characteristics of quinoxyfen. Further information regarding EPA drinking water models used in pesticide exposure assessment can be found at http://www.epa.gov/​oppefed1/​models/​water.

-Typically EPA evaluates the potential for human exposure to pesticides in drinking water through an assessment of available surface water and ground water monitoring data and modeling. For quinoxyfen, no monitoring data were available for use in this drinking water assessment. Therefore, potential human exposures to quinoxyfen were evaluated through modeling.

-The Agency used the FQPA Index Reservoir Screening Tool (FIRST) to calculate the surface water Estimated Exposure Concentrations (EECs) and the screening model SCI-GROW to calculate the groundwater EECs. The Agency considered residues of quinoxyfen per se, plus a metabolite, 3-OH quinoxyfen, in modeling studies. To do this, aerobic soil metabolism and aerobic aquatic metabolism half-lives determined for the parent compound in the guideline studies were recalculated using concentration data for the parent compound plus 3-OH quinoxyfen when the latter compound was present. Additionally, the Agency was restricted to the use of soil adsorption coefficients determined only for the parent compound; however, other available information from the guideline studies indicates that 3-OH quinoxyfen has mobility in soil similar to that of the parent compound. Because hydroxylation (the addition of the 3-OH) could increase its mobility relative to quinoxyfen, this metabolite has the potential to reach drinking water sources in significant quantities. -

-For the surface water and groundwater assessments, EECs were determined using a maximum annual application rate for cherries of 0.55 lb a.i./A (five applications of 0.114 lb a.i./A/application).

-Based on the FIRST and SCI-GROW models, the estimated environmental concentrations (EECs) of quinoxyfen for chronic exposures are estimated to be 0.84 ppb for surface water and 0.006 ppb for ground water. Model estimates of drinking water concentrations were directly entered into the dietary exposure model (DEEM-FCID).

-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). Quinoxyfen is not registered for use on any sites that would result in residential exposure.

-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 quinoxyfen and any other substances and quinoxyfen 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 quinoxyfen 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 Start Printed Page 50353and postnatal toxicity and the completeness of the data base on toxicity and exposure unless EPA determines 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 value based on the use of traditional uncertainty factors and/or special FQPA safety factors, as appropriate.

-2. Prenatal and postnatal sensitivity. There is no quantitative or qualitative evidence of increased susceptibility of rat and rabbit fetuses to in utero exposure in developmental studies. There is evidence of increased quantitative susceptibility (minimal decrease in F1a pup weights) in the rat multi-generation reproduction study, but the concern is low since: (1) The effects in pups are well-characterized with a clear NOAEL; (2) the pup effects are minimal at the LOAEL and only noted in the first-generation offspring; and (3) the doses and endpoints selected for regulatory purposes would address the concerns of the pup effects noted in the rat reproduction study. Therefore, there are no residual uncertainties for prenatal/postnatal toxicity in this study.

-3. Conclusion. There is a complete toxicity data base for quinoxyfen and exposure data are complete or are estimated based on data that reasonably account for potential exposures. There are no residual uncertainties for prenatal/postnatal toxicity. No additional safety factor is needed for data base uncertainties. No clinical sign of neurotoxicity or neuropathology was seen in the data base, including acute and subchronic neurotoxicity studies. A developmental neurotoxicity study is not required. Therefore, EPA determined that the 10X SF to protect infants and children should be reduced to 1X.

E. Aggregate Risks and Determination of Safety

-1. Acute risk. An endpoint of concern was not identified to quantitate acute-dietary risk to the general population or to the subpopulation females 13-50 years old. As a result, no acute risk is expected from exposure to quinoxyfen.

-2. Chronic risk. Using the exposure assumptions described in this unit for chronic exposure, EPA has concluded that exposure to quinoxyfen from (food + water) will utilize 1.3% of the cPAD for the U.S. population, <1% of the cPAD for infants <1 year old), and 2.0% of the cPAD for children (1 to 2 years old) the subpopulation at greatest exposure. There are no residential uses for quinoxyfen that result in chronic residential exposure to quinoxyfen.

-3. Short-term risk. Short-term aggregate exposure takes into account residential exposure plus chronic exposure to food and water (considered to be a background exposure level). Quinoxyfen is not registered for use on any sites that would result in residential exposure. Therefore, the aggregate risk is the sum of the risk from food and water, which do not exceed the Agency's level of concern.

-4. Intermediate-term risk. Intermediate-term aggregate exposure takes into account residential exposure plus chronic exposure to food and water (considered to be a background exposure level). Quinoxyfen is not registered for use on any sites that would result in residential exposure. Therefore, the aggregate risk is the sum of the risk from food and water, which do not exceed the Agency's level of concern.

-5. Aggregate cancer risk for U.S. population. Quinoxyfen has been classified as “not likely to be carcinogenic to humans.” Therefore, quinoxyfen 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 quinoxyfen residues.

IV. Other Considerations

A. Analytical Enforcement Methodology

-A practical analytical method is available to monitor and enforce the tolerances of quinoxyfen residues in crops. The analytical method uses capillary gas chromatography and mass spectrometry detector (GC-MSD) with limits of quantitation (LOQ) of approximately 0.01 ppm. The method is adequate for collecting data and enforcing tolerances for quinoxyfen residues in/on the subject crops. There are no livestock feed items associated with these petitions, therefore, data collection and tolerance enforcement methods for livestock commodities are not required.

B. International Residue Limits

-There are no Mexican, Canadian or Codex maximum residue limits (MRLs) established for quinoxyfen in/on crops considered in this action. Therefore, no compatibility issues exist for these tolerances.

V. Conclusion

-Therefore, the tolerance is established for residues of quinoxyfen, 5,7-dichloro-4-(4-fluorophenoxy) quinoline in or on lettuce, head at 7.0 ppm and lettuce, leaf at 19 ppm; melon, subgroup 9A at 0.08 ppm; pepper, bell at 0.35 ppm; pepper, nonbell at 1.7 ppm; and strawberry at 0.90 ppm. -.

VI. 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 Start Printed Page 50354Agency 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.

VII. 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).
