Final rule.


This regulation establishes a time-limited tolerance for diflubenzuron and its metabolites p-chlorophenylurea and p-chloroaniline in or on lemon. This action is in response to EPA's granting of an emergency exemption under section 18 of the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA) authorizing use of the pesticide on lemon. This regulation establishes a maximum permissible level for combined residues of diflubenzuron and its metabolites p-chlorophenylurea and p-chloroaniline, in this food commodity. The tolerance expires and is revoked on December 31, 2010.


This regulation is effective July 25, 2007. Objections and requests for hearings must be received on or before September 24, 2007, and must be filed in accordance with the instructions provided in 40 CFR part 178 (see also Unit I.C. of the SUPPLEMENTARY INFORMATION.

II. Background and Statutory Findings

EPA, on its own initiative, in accordance with sections 408(e) and 408(l)(6) of the Federal Food, Drug, and Cosmetic Act (FFDCA), 21 U.S.C. 346a, is establishing a tolerance for of the insecticide, diflubenzuron and its metabolites p-chlorophenylurea and p-chloroaniline, in or on lemon at 0.8 parts per million (ppm). This tolerance expires and is revoked on December 31, 2010. EPA will publish a document in the Federal Register to remove the revoked tolerance from the Code of Federal Regulations (CFR).

Section 408(l)(6) of the FFDCA requires EPA to establish a time-limited tolerance or exemption from the requirement for a tolerance for pesticide chemical residues in food that will result from the use of a pesticide under an emergency exemption granted by EPA under section 18 of FIFRA. Such tolerances can be established without providing notice or period for public comment. EPA does not intend for its actions on section 18 related tolerances to set binding precedents for the application of section 408 of the FFDCA and the new safety standard to other tolerances and exemptions. Section 408(e) of the FFDCA allows EPA to establish a tolerance or an exemption from the requirement of a tolerance on its own initiative, i.e., without having received any petition from an outside party.

Section 408(b)(2)(A)(i) of the 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 the 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 the 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. . . ”

Section 18 of the FIFRA authorizes EPA to exempt any Federal or State agency from any provision of FIFRA, if EPA determines that “emergency conditions exist which require such exemption.” This provision was not amended by the Food Quality Protection Act of 1996 (FQPA). EPA has established regulations governing such emergency exemptions in 40 CFR part 166.

EPA is also revising the tolerance expression in § 180.377(b) to be consistent with the preferable wording as expressed in § 180.377(a)(2).

III. Emergency Exemption for Diflubenzuron on Lemon and FFDCA Tolerances

In the fall of 2005 and spring of 2006, active infestations of Diaprepes root weevil were detected including one lemon orchard (28 acres) in commercial sites in Long Beach, Newport Beach, Carlsbad, Encintas, and La Jolla, California. The California Department of Food and Agriculture (CDFA) has quarantined these sites and has already initiated eradication treatments using products that impact various life stages of this insect. The emergency use of diflubenzuron is needed to treat the egg stage of the weevil when they are detected in lemon. The overall program involves treatment for larval and adult stages as well. EPA has authorized under FIFRA section 18 the use of diflubenzuron on lemon for control of Diaprepes root weevil in California. After having reviewed the submission, EPA concurs that emergency conditions exist for this State.

As part of its assessment of this emergency exemption, EPA assessed the potential risks presented by residues of diflubenzuron in or on lemon. In doing so, EPA considered the safety standard in section 408(b)(2) of the FFDCA, and EPA decided that the necessary tolerance under section 408(l)(6) of the FFDCA would be consistent with the safety standard and with FIFRA section 18. Consistent with the need to move quickly on the emergency exemption in order to address an urgent non-routine situation and to ensure that the resulting food is safe and lawful, EPA is issuing this tolerance without notice and opportunity for public comment as provided in section 408(l)(6) of the FFDCA. Although this tolerance expires and is revoked on December 31, 2007, under section 408(l)(5) of the FFDCA, residues of the pesticide not in excess of the amounts specified in the tolerance remaining in or on lemon after that date will not be unlawful, provided the pesticide is applied in a manner that was lawful under FIFRA, and the residues do not exceed a level that was authorized by this tolerance at the time of that application. EPA will take action to revoke this tolerance earlier if any experience with, scientific data on, or other relevant information on this pesticide indicate that the residues are not safe.

Because this tolerance is being approved under emergency conditions, EPA has not made any decisions about whether diflubenzuron meets EPA's registration requirements for use on lemon or whether a permanent tolerance for this use would be appropriate. Under these circumstances, EPA does not believe that this tolerance serves as a basis for registration of diflubenzuron by a State for special local needs under FIFRA section 24(c). Nor does this tolerance serve as the basis for any State other than California to use this pesticide on this crop under section 18 of FIFRA without following all provisions of EPA's regulations implementing FIFRA section 18 as identified in 40 CFR part 166.

IV. Aggregate Risk Assessment and Determination of Safety

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​fedrgstr/​EPA-PEST/​1997/​November/​Day-26/​p30948.htm.

Consistent with section 408(b)(2)(D) of the 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 diflubenzuron and to make a determination on aggregate exposure, consistent with section 408(b)(2) of the FFDCA, for a time-limited tolerance for combined residues of diflubenzuron in or on lemon at 0.8 ppm. EPA's assessment of the dietary exposures and risks associated with establishing the tolerance follows.

A. 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. More information can be found on the general principles EPA uses in risk characterization at​pesticides/​health/​human.htm. A summary of the toxicological endpoints for diflubenzuron used for human risk assessment is discussed in Unit III.B. of the final rule published in the Federal Register of September 19, 2002 (67 FR 59006) (FRL-7200-4).

B. Exposure Assessment

1. Dietary exposure from food and feed uses. Tolerances for residues of diflubenzuron are established under 40 CFR 180.377. Tolerances listed in 40 CFR 180.377(a)(1) are expressed in terms of diflubenzuron per se. Under this section, tolerances of 0.05-6.0 ppm are established for residues in/on eggs; milk; fat and meat of cattle, goat, hog, horse, poultry, and sheep; poultry meat byproducts; cottonseed; mushroom; grapefruit, orange (sweet); tangerine; soybean hulls; and globe artichoke. Tolerances listed in 40 CFR 180.377(a)(2) are expressed in terms of the combined residues of diflubenzuron and its metabolites 4-chlorophenylurea (CPU) and 4-chloroaniline (PCA). Under this section, tolerances of 0.02-55.0 pm are established for residues in/on rice grain and straw; barley grain, straw, and hay; oat, forage, grain, hay, and straw; wheat forage, grain, hay, and straw; grain aspirated fractions; brassica, leafy greens, subgroup 5B; grass, forage, fodder, and hay, group 17; tree nuts (group 14); peanut, peanut hay and refined oil; pistachios; fruit, stone (group 12) except cherry; meat byproducts of cattle, goat, hog, horse, and sheep; pear; pepper; pummelo; turnip greens; and almond hulls. Time-limited tolerances listed in 40 CFR 180.377(b) are expressed in terms of the combined residues of diflubenzuron and its metabolites CPU and PCA, expressed as the parent diflubenzuron, in connection with use of the pesticide under Section 18 Emergency Exemptions granted by EPA. Risk assessments were conducted by EPA to assess dietary exposures from diflubenzuron in food as follows:

i. Acute exposure. Acute dietary 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. The diflubenzuron toxicology studies indicated no possibility of such an effect for either the general U.S. population (including infants and children) or the females 13-50 years old population subgroup for diflubenzuron; therefore, an acute dietary exposure analysis was not performed.

ii. Chronic exposure. In conducting this chronic dietary risk assessment the Dietary Exposure Evaluation Model (DEEM-FCIDTM) analysis evaluated the individual food consumption as reported by respondents in the U.S. Department of Agriculture (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: A chronic dietary-exposure assessment was conducted using the established/recommended tolerances for all food commodities, 100% CT information for all proposed and existing uses, and DEEM(TM) Version 7.81 default processing factors for some processed commodities.

iii. Cancer. The Agency has classified diflubenzuron as “Group E,” evidence of non-carcinogenicity for humans, based on lack of evidence of carcinogenicity in rats and mice. There are also two metabolites of diflubenzuron; PCA and CPU. PCA tested positive for splenic tumors in male rats and hepatocellular adenomas/carcinomas in male mice in a National Toxicology Program (NTP) study. Therefore, EPA classified PCA as a “Group B2” probable human carcinogen. The Agency determined for those commodities that contained PCA and CPU, the Q1* of PCA should be used to calculate the cancer risk from the sum of these two metabolites.

Based on the submitted metabolism studies, there are two possible sources for dietary exposure to PCA and CPU: Residues in mushrooms and residues in milk and liver. Because human exposure to PCA and CPU will not be affected by the proposed new uses, and EPA has previously concluded that exposure to these compounds is safe, therefore, the cancer dietary risk from PCA and CPU will not be addressed in this document. For a detailed discussion on the exposure and risks to PCA and CPU, please refer to the September, 2002 Federal Register document titled Diflubenzuron; Pesticide Tolerances (September 19, 2002, FR 67 59006);​fedrgstr/​EPA-PEST/​2002/​September/​Day-19/​p23818.htm.

2. Dietary exposure from drinking water. The Agency lacks sufficient monitoring exposure data to assess dietary exposure to diflubenzuron in drinking water based on measured drinking water concentrations. 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 diflubenzuron. Further information regarding EPA drinking water models used in pesticide exposure assessment can be found at​oppfed1/​models/​water/​index.htm. Based on the Pesticide Root Zone Model/Exposure Analysis Modeling System (PRZM/EXAMS) and Screening Concentrations in Ground Water (SCI-GROW) models, the estimated environmental concentrations (EECs) of diflubenzuron and the major degradate CPU for chronic exposures are estimated Start Printed Page 40757to be 2.76 parts per billion (ppb) for surface water and 0.208 ppb for ground water. Modeled estimates of drinking water concentrations were directly entered into the dietary exposure model (DEEM-FCIDTM, Version 2.03). For chronic dietary risk assessment, the annual average concentration of 2.76 ppb was used to represent the drinking water contribution to chronic dietary exposure for diflubenzuron.

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). Although there are no registered homeowner uses, there are registered uses for professional applications to outdoor residential and recreational areas to control mosquitoes, moths, and other insects. In addition, certain residential use sites will be treated in association with this emergency exemption for the control of the Diaprepes root weevil. However, EPA considers the potential for post-application residential exposure to be low. Further, diflubenzuron has a low dermal absorption rate (0.5%) and will be only applied to the tree canopy.

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 diflubenzuron and any other substances and diflubenzuron 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 diflubenzuron 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 OPP concerning common mechanism determinations and procedures for cumulating effects from substances found to have a common mechanism on EPA's website at​pesticides/​cumulative/​.

C. Safety Factor for Infants and Children

1. In general. Section 408 of the 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 database on toxicity and exposure unless EPA determines 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.

2. Prenatal and postnatal sensitivity. Based on the developmental and reproductive toxicity studies, there is no indication of increased susceptibility of rats or rabbits to in utero or postnatal exposure.

3. Conclusion. There is a complete toxicity database for diflubenzuron and exposure data are complete or are estimated based on data that reasonably accounts for potential exposures. EPA determined that the additional FQPA 10X safety factor to protect infants and children was not needed. This decision was based on the following:

i. There is a complete toxicity database for diflubenzuron;

ii. There is no indication of increased susceptibility of rats or rabbits to in utero or postnatal exposure;

iii. A developmental neurotoxicity study (DNT) with diflubenzuron is not required;

iv. Food and drinking water exposure assessments will not underestimate the potential exposure for infants and children; and

v. The potential for post-application residential exposures are expected to be limited. Due to the low dermal absorption rate (0.5%) of diflubenzuron, and since it is only applied to the tree canopy to control gypsy moths and mosquitoes, minimal bystander contact is expected.

D. Aggregate Risks and Determination of Safety

1. Acute risk. Because there were no toxic effects attributable to a single dose of diflubenzuron, it is not expected to pose an acute risk.

2. Chronic risk. Using the exposure assumptions described in this unit for chronic exposure, EPA has concluded that exposure to diflubenzuron from food will utilize 12% of the cPAD for the U.S. population, 12% of the cPAD for all infants less than 1 year old and 38% of the cPAD for children 1-2 years old. There are no residential uses for diflubenzuron that result in chronic residential exposure to diflubenzuron. EPA does not expect the aggregate exposure to exceed 100% of the cPAD.

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).

The aggregate risk is the sum of the risk from food and water, which do not exceed the Agency's LOC.

4. Intermediate-term risk. Intermediate-term aggregate exposure takes into account non-dietary, non-occupational exposure plus chronic exposure to food and water (considered to be a background exposure level).

The aggregate risk is the sum of the risk from food and water, which do not exceed the Agency's LOC.

5. Aggregate cancer risk for U.S. population. Based on the available evidence, which included adequate carcinogenicity studies in rats and mice, and battery of negative mutagenicity studies, diflubenzuron has been classified as “Group E,” evidence of non-carcinogenicity for humans, by the Agency. As noted in Unit III.C.1.iii. of this document, the Agency has concluded that human exposure to PCA and CPU (metabolites of diflubenzuron) will not be affected by the proposed new uses. EPA has previously found aggregate exposure to these compounds to be safe. (September 19, 2002, 67 FR 59006);​fedrgstr/​EPA-PEST/​2002/​September/​Day-19/​p23818.htm.

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 diflubenzuron residues.

V. Other Considerations

A. Analytical Enforcement Methodology

There are adequate enforcement methods, published in the Pesticide Analytical Manual (PAM, Vol. II), for determining diflubenzuron residues of concern. In addition, a new analytical methodology for plant commodities was successfully validated by an independent laboratory as well as by Agency chemists at the Analytical Chemistry Branch (ACB)/Biological and Economics Analysis Division (BEAD) in conjunction with an approved rice petition (PP 8F4925). The new methods were forwarded to the Food and Drug Administration (FDA) for publication in PAM Vol. II as Roman Numeral Methods. These methods can separately determine residues of diflubenzuron by Start Printed Page 40758gas chromatography/electron-capture detection (GC/ECD), CPU by GC/ECD, and PCA by GC/mass spectrometry (MS).

B. International Residue Limits

The Codex Alimentarius has established maximum residue limits (MRL), expressed in terms of diflubenzuron per se, for many commodities including: Apple (5 ppm), citrus fruits (0.5 ppm), edible offal (mammalian) (0.1 ppm), eggs (0.05 ppm), meat (from mammals other than marine mammals) (0.1 ppm), milks (0.02 ppm), mushrooms (0.3 ppm), pear (5 ppm), pome fruits (5 ppm), poultry meat (0.05 ppm), rice (0.01 ppm), and rice straw and fodder (dry) (0.7 ppm). As the U.S. residue definition includes CPU and PCA, compatibility is not possible with the proposed tolerance.

VI. Conclusion

Therefore, the tolerance is established for of the insecticide diflubenzuron, (N-[[(4-chlorophenyl)amino]carbonyl]-2,6- difluorobenzamide and its metabolites 4-chlorophenylurea and 4-chloroaniline in or on lemon at 0.8 ppm.

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, this rule is not subject to Executive Order 13211, Actions Concerning Regulations That Significantly Affect Energy Supply, Distribution, or Use (66 FR 28355, May 22, 2001) or Executive Order 13045, entitled Protection of Children from Environmental Health Risks and Safety Risks (62 FR 19885, April 23, 1997). This final rule does not contain any information collections subject to OMB approval under the Paperwork Reduction Act (PRA), 44 U.S.C. 3501 et seq., nor does it require any special considerations under Executive Order 12898, entitled Federal Actions to Address Environmental Justice in Minority Populations and Low-Income Populations (59 FR 7629, February 16, 1994).

Since tolerances and exemptions that are established on the basis of a petition under section 408(d) of FFDCA, such as the 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 6, 2000) do not apply to this rule. In addition, This rule does not impose any enforceable duty or contain any unfunded mandate as described under Title II of the Unfunded Mandates Reform Act of 1995 (UMRA) (Public Law 104-4).

This action does not involve any technical standards that would require Agency consideration of voluntary consensus standards pursuant to section 12(d) of the National Technology Transfer and Advancement Act of 1995 (NTTAA), Public Law 104-113, section 12(d) (15 U.S.C. 272 note).

VIII. 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).
