AGENCY:

Environmental Protection Agency (EPA).

ACTION:

Final rule.

SUMMARY:

This regulation establishes time-limited tolerances for combined residues of diflubenzuron and its metabolites p-chlorophenylurea and p-chloroaniline in or on alfalfa, forage and alfalfa, hay. 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 alfalfa and mixed grass/alfalfa fields. This regulation establishes a maximum permissible level for residues of diflubenzuron and its metabolites p-chlorophenylurea and p-chloroaniline, in these food commodities. The time-limited tolerances expire and are revoked on December 31, 2011.

DATES:

This regulation is effective November 28, 2008. Objections and requests for hearings must be received on or before January 27, 2009, 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 FFDCA, 21 U.S.C. 346a(e) and 346a(1)(6), is establishing time-limited tolerances for combined residues of the insecticide diflubenzuron and its metabolites p-chlorophenylurea and p-chloroaniline, in or on alfalfa, forage and alfalfa, hay at 6 parts per million (ppm). These time-limited tolerances expire and are revoked on December 31, 2011. EPA will publish a document in the Federal Register to remove the revoked tolerances from the CFR.

Section 408(l)(6) of 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 time-limited tolerances to set binding precedents for the application of section 408 of FFDCA and the new safety standard to other tolerances and exemptions. Section 408(e) of 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 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. . . .”

Section 18 of 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.” EPA has established regulations governing such emergency exemptions in 40 CFR part 166.

III. Emergency Exemption for Diflubenzuron on Alfalfa and FFDCA Tolerances

The United States Department of Agriculture, Animal and Plant Health Inspection Service (USDA/APHIS) requested the use diflubenzuron to control Mormon crickets and grasshoppers on alfalfa grown for hay to protect pollinators of Spalding's catchfly, a threatened plant species endemic to the proposed treatment area in Montana. The alfalfa fields are interspersed within the rangeland spray blocks. EPA evaluated this request and found that USDA/APHIS had identified an emergency situation. Thus, EPA concurred on the request.

In a separate action, the Oregon Department of Agricultural (ODA) declared a crisis emergency exemption for use of diflubenzuron to control the same pests on alfalfa grown for hay, and mixed grass/alfalfa hay on June 30, 2008.

As part of its evaluation of the emergency exemption application, EPA assessed the potential risks presented by combined residues of diflubenzuron in or on alfalfa, forage and alfalfa, hay. In doing so, EPA considered the safety Start Printed Page 72354standard in section 408(b)(2) of FFDCA, and EPA decided that the necessary tolerance under section 408(l)(6) of FFDCA would be consistent with the safety standard and with FIFRA section 18. EPA has previously evaluated the use of diflubenzuron on alfalfa and established time-limited tolerances initially for a similar use in Federal Register: September 20, 2002 (67 FR 59177), OPP-2002-0253; FRL-7273-7 in association with earlier emergency exemption request. This notice re-establishes those time-limited tolerances. 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 FFDCA. Although these time-limited tolerances expire and are revoked on December 31, 2011, under section 408(l)(5) of FFDCA, residues of the pesticide not in excess of the amounts specified in the tolerance remaining in or on alfalfa, forage and alfalfa, hay after that date will not be unlawful, provided the pesticide was applied in a manner that was lawful under FIFRA, and the residues do not exceed a level that was authorized by these time-limited tolerances at the time of that application. EPA will take action to revoke these time-limited tolerances earlier if any experience with, scientific data on, or other relevant information on this pesticide indicate that the residues are not safe.

Because these time-limited tolerances are being approved under emergency conditions, EPA has not made any decisions about whether it meets FIFRA's registration requirements for use on alfalfa, forage and alfalfa, hay or whether permanent tolerances for this use would be appropriate. Under these circumstances, EPA does not believe that this time-limited tolerance decision 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 persons in any State other than USDA/ODA to use this pesticide on these crops under FIFRA section 18 absent the issuance of an emergency exemption applicable within that State. For additional information regarding the emergency exemption for diflubenzuron, contact the Agency's Registration Division at the address provided under FOR FURTHER INFORMATION CONTACT.

IV. Aggregate Risk Assessment and Determination of Safety

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

Consistent with the factors specified in section 408(b)(2)(D) of FFDCA, EPA has reviewed the available scientific data and other relevant information in support of this action. EPA has sufficient data to assess the hazards of and to make a determination on aggregate exposure expected as a result of this emergency exemption request and the time-limited tolerances for combined residues of diflubenzuron on alfalfa, forage and alfalfa, hay at 6 ppm. EPA's assessment of exposures and risk associated with establishing time-limited tolerances follows.

A. Toxicological Endpoints

For hazards that have a threshold below which there is no appreciable risk, a toxicological point of departure (POD) is identified as the basis for derivation of reference values for risk assessment. The POD may be defined as the highest dose at which no adverse effects are observed (the NOAEL) in the toxicology study identified as appropriate for use in risk assessment. However, if a NOAEL cannot be determined, the lowest dose at which adverse effects of concern are identified (the LOAEL) or a Benchmark Dose (BMD) approach is sometimes used for risk assessment. Uncertainty/safety factors (UFs) are used in conjunction with the POD to take into account 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. Safety is assessed for acute and chronic dietary risks by comparing aggregate food and water exposure to the pesticide to the acute population adjusted dose (aPAD) and chronic population adjusted dose (cPAD). The aPAD and cPAD are calculated by dividing the POD by all applicable UFs. Aggregate short-, intermediate-, and chronic-term risks are evaluated by comparing food, water, and residential exposure to the POD to ensure that the margin of exposure (MOE) called for by the product of all applicable UFs is not exceeded. This latter value is referred to as the Level of Concern (LOC).

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 greater than that 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 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. In evaluating dietary exposure to diflubenzuron, EPA considered exposure under the time-limited tolerances established by this action as well as all existing diflubenzuron tolerances in (40 CFR 180.377). EPA assessed dietary exposures from diflubenzuron in food as follows:

i. Acute exposure. No such effects were identified in the toxicological studies for diflubenzuron, therefore, a quantitative acute dietary exposure assessment is unnecessary.

ii. Chronic exposure. In conducting the chronic dietary exposure assessment EPA used the food consumption data from the USDA 1994-1996 and 1998 CSFII. As to residue levels in food, EPA used the established/recommended tolerances for all food commodities, 100 percent crop treated (PCT) information for all proposed and existing uses, and Dietary Exposure Evaluation Model (DEEMTM) 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 Start Printed Page 72355diflubenzuron; 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); http://www.epa.gov/​fedrgstr/​EPA-PEST/​2002/​September/​Day-19/​p23818.htm.

2. Dietary exposure from drinking water. The Agency used screening level water exposure models in the dietary exposure analysis and risk assessment for diflubenzuron in drinking water. These simulation models take into account data on the physical, chemical, and fate/transport characteristics of diflubenzuron. Further information regarding EPA drinking water models used in pesticide exposure assessment can be found at http://www.epa.gov/​oppefed1/​models/​water/​index.htm.

Based on the Pesticide Root Zone Model/Exposure Analysis Modeling System (PRZM/EXAMS) and Screening Concentration in Ground Water (SCI-GROW) models, the estimated drinking water concentrations (EDWCs) of diflubenzuron and the major degradate CPU for chronic exposures are estimated to be 2.76 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 DEEMTM-Food Commodity Intake Database (FCID), 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. However, the potential for post-application residential exposure is 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, minimal non-occupational exposure is expected.

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 diflubenzuron to share a common mechanism of toxicity with 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 assumed that diflubenzuron 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 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.

C. 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 SF when reliable data available to EPA support the choice of a different factor.

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 has determined that reliable data show that the safety of infants and children would be adequately protected if the FQPA SF were reduced to 1X. That decision is based on the following findings:

i. The toxicity database for diflubenzuron is complete.

ii. There is no indication that diflubenzuron is a neurotoxic chemical and there is no need for a developmental neurotoxicity study or additional UFs to account for neurotoxicity.

iii. There is no evidence that diflubenzuron 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 EPA made conservative (protective) assumptions in the ground and surface water modeling used to assess exposure to diflubenzuron in drinking water. EPA used similarly conservative assumptions to assess postapplication exposure of children as well as incidental oral exposure of toddlers. These assessments will not underestimate the exposure and risks posed by diflubenzuron. There are currently no registered or proposed residential (non-occupational) uses of diflubenzuron for homeowners. Although there are no registered homeowner uses, there is potential for professional applications to outdoor residential and recreational areas. However, 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

EPA determines whether acute and chronic pesticide exposures are safe by comparing aggregate exposure estimates to the aPAD and cPAD. The aPAD and cPAD represent the highest safe exposures, taking into account all appropriate SFs. EPA calculates the aPAD and cPAD by dividing the POD by all applicable UFs. For linear cancer risks, EPA calculates the probability of Start Printed Page 72356additional cancer cases 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 POD to ensure that the MOE called for by the product of all applicable UFs is not exceeded.

1. Acute risk. An acute aggregate risk assessment takes into account exposure estimates from acute dietary consumption of food and drinking water. No adverse effect resulting from a single-oral exposure was identified, therefore, no acute dietary endpoint was selected. Therefore, diflubenzuron 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 chronic exposure to diflubenzuron from food and water 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.

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).

Diflubenzuron is not registered for any use patterns that would result in residential exposure. Therefore, the short-term aggregate risk is the sum of the risk from exposure to diflubenzuron through food and water.

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

Diflubenzuron is not registered for any use patterns that would result in intermediate-term residential exposure. Therefore, the intermediate-term aggregate risk is the sum of the risk from exposure to diflubenzuron through food and water, which has already been addressed.

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 IV.B.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); at http://www.epa.gov/​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, or 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 gas chromatography/electron-capture detection (GC/ECD), CPU by GC/ECD, and PCA by GC/mass spectrometry (MS).

B. International Residue Limits

There are no Codex maximum residue limits established for diflubenzuron on alfalfa forage and hay.

VI. Conclusion

Therefore, time-limited tolerances are established for combined residues of the insecticide diflubenzuron, (N-[[(4-chlorophenyl)amino]carbonyl]-2,6-difluorobenzamide and its metabolites 4-chlorophenylurea and 4-chloroaniline, in or on alfalfa, forage and alfalfa, hay at 6 ppm. These tolerances expire and are revoked on December 31, 2011.

VII. Statutory and Executive Order Reviews

This final rule establishes tolerances under sections 408(e) and 408(l)(6) of FFDCA in response to a petition submitted to the Agency. The Office of Management and Budget (OMB) has exempted these types of actions from review under Executive Order 12866, entitled Regulatory Planning and Review (58 FR 51735, October 4, 1993). Because this final rule has been exempted from review under Executive Order 12866, this final rule is not subject to Executive Order 13211, entitled Actions Concerning Regulations That Significantly Affect Energy Supply, Distribution, or Use (66 FR 28355, May 22, 2001) or Executive Order 13045, entitled Protection of Children from Environmental Health Risks and Safety Risks (62 FR 19885, April 23, 1997). This final rule does not contain any information collections subject to OMB approval under the Paperwork Reduction Act (PRA), 44 U.S.C. 3501 et seq., nor does it require any special considerations under Executive Order 12898, entitled Federal Actions to Address Environmental Justice in Minority Populations and Low-Income Populations (59 FR 7629, February 16, 1994).

Since tolerances and exemptions that are established in accordance with sections 408(e) and 408(l)(6) of FFDCA, such as the tolerances in this final rule, do not require the issuance of a proposed rule, the requirements of the Regulatory Flexibility Act (RFA) (5 U.S.C. 601 et seq.) do not apply.

This final rule directly regulates growers, food processors, food handlers, and food retailers, not States or tribes, nor does this action alter the relationships or distribution of power and responsibilities established by Congress in the preemption provisions of section 408(n)(4) of FFDCA. As such, the Agency has determined that this action will not have a substantial direct effect on States or tribal governments, on the relationship between the national government and the States or tribal governments, or on the distribution of power and responsibilities among the various levels of government or between the Federal Government and Indian tribes. Thus, the Agency has determined that Executive Order 13132, entitled Federalism (64 FR 43255, August 10, 1999) and Executive Order 13175, entitled Consultation and Coordination with Indian Tribal Governments (65 FR 67249, November 9, 2000) do not apply to this final rule. In addition, this final rule does not impose any enforceable duty or contain any unfunded mandate as described under Title II of the Unfunded Mandates Reform Act of 1995 (UMRA) (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 Start Printed Page 72357that 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).
