Summary of Petitioned-for Tolerance
In the Federal Register of June 23, 2010 (75 FR 35801) (FRL-8831- 3), EPA issued a notice pursuant to section 408(d)(3) of FFDCA, 21
U.S.C. 346a(d)(3), announcing the filing of a pesticide petition (PP 0F7708) by Makhteshim-Agan of North America, Inc., 4515 Falls of Neuse
Road, Raleigh, NC 27609 as well as the filing of a pesticide petition
(PP 0E7723) by IR-4, 500 College Road East, Suite 201W, Princeton, NJ 08540. The IR-4 petition (PP 0E7723) requested that 40 CFR 180.598 be amended by establishing tolerances for residues of the insecticide novaluron, (N -[3-chloro-4-[1,1,2-trifluoro-2-
(trifluoromethoxy)ethoxy] phenyl]amino] carbonyl]-2,6- difluorobenzamide), in or on corn, sweet, kernels plus cob with husks removed at 0.05 parts per million (ppm); corn, sweet, forage at 20 ppm; and corn, sweet, stover at 50 ppm and to increase the established livestock tolerances for residues of novaluron in or on milk from 1.0 to 1.5 ppm, and milk fat from 20 to 35 ppm, respectively. The
Makhteshim-Agan petition (PP 0F7708) requested novaluron tolerances for all food commodities (other than those already covered by a higher tolerance as a result of use on growing crops) in food handling establishments where food products are held, processed or prepared at 0.01 ppm. That notice referenced a summary of the petitions prepared by
Makhteshim-Agan of North America, Inc, the registrant, which is available in the docket, http://www.regulations.gov. There were no comments received in response to the notice of filing for PP 0F7708.
Comments were received on the notice of filing for PP 0E7723. EPA's response to these comments is discussed in Unit IV.C.
Based upon review of the data supporting the petition, EPA has revised the tolerances for sweet corn forage and determined it is not appropriate to raise the existing tolerances for milk and milk fat. The
EPA also determined it is appropriate to revise several existing livestock commodities based on the proposed sweet corn use. The reasons for these changes are explained in Unit IV.D.

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 section 408(b)(2)(D) of FFDCA, and 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 for novaluron including exposure resulting from the tolerances established by this action.
EPA's assessment of exposures and risks associated with novaluron follows.
-
Toxicological Profile
EPA has evaluated the available toxicity data and considered its validity, completeness, and reliability as well as the relationship of the results of the studies to human risk. EPA has also considered available information concerning the variability of the sensitivities of major identifiable subgroups of consumers, including infants and children.
Novaluron has low acute toxicity via the oral, dermal, and inhalation routes. No ocular or dermal irritation was noted. Novaluron is not a dermal sensitizer. In subchronic and chronic toxicity studies, novaluron primarily produced hematotoxic effects (toxicity to blood) such as methemoglobinemia, decreased hemoglobin, decreased hematocrit, and decreased red blood corpuscles (RBCs or erythrocytes) that were associated with compensatory erythropoiesis. Increased spleen weights and/or hemosiderosis in the spleen were considered to be due to enhanced removal of damaged erythrocytes and not to an immunotoxic effect.
There was no maternal or developmental toxicity seen in the rat and rabbit developmental toxicity studies up to the limit doses. In the two-generation reproductive toxicity study in rats, both parental and offspring toxicity (increased spleen weights) were observed at the same dose. Reproductive toxicity (decreases in epididymal sperm counts and increase age at preputial separation in the F1 generation) was observed at a higher dose only in males.
Signs of neurotoxicity were seen in the rat acute neurotoxicity study at the limit dose, including clinical signs (piloerection, fast/ irregular breathing), functional observation battery (FOB) parameters
(head swaying, abnormal gait) and neuropathology (sciatic and tibial nerve degeneration). However, no signs of neurotoxicity or neuropathology were observed in the subchronic neurotoxicity study in rats or in any other subchronic or chronic toxicity study in rats, mice or dogs. Therefore, there is no concern for neurotoxicity resulting from exposure to novaluron.
There was no evidence of carcinogenic potential in either the rat or mouse carcinogenicity studies and no evidence of mutagenic activity in the submitted mutagenicity studies, including a bacterial
(Salmonella, E. coli) reverse mutation assay, an in vitro mammalian chromosomal aberration assay, an in vivo mouse bone-marrow micronucleus assay and a bacterial DNA damage or repair assay. Based on the results of these studies, EPA has classified novaluron as ``not likely to be carcinogenic to humans.''
Specific information on the studies received and the nature of the adverse effects caused by novaluron 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 at http://www.regulations.gov in document ``Novaluron: Human-Health Risk
Assessment for Proposed Section 3 Uses on Sweet Corn and in Food--or
Feed-Handling Establishments'' at pages 53-56 in docket ID number EPA-
HQ-OPP-2010-0466.

Toxicological Points of Departure/Levels of Concern
Once a pesticide's toxicological profile is determined, EPA identifies toxicological points of departure (POD) and levels of concern to use in evaluating the risk posed by human exposure to the pesticide. For hazards that have a threshold below which there is no appreciable risk, the toxicological POD is used as the basis for derivation of reference values for risk assessment. PODs are developed based on a careful analysis of the doses in each toxicological study to determine the dose at which no adverse effects are observed (the NOAEL) and the lowest dose at which adverse effects of concern are identified
(the LOAEL). Uncertainty/safety factors are used in conjunction with the POD to calculate a safe exposure level--generally referred to as a population-adjusted dose (PAD) or a reference dose (RfD)--and a safe margin of exposure (MOE). For non-threshold risks, the Agency assumes that any amount of exposure will lead to some degree of risk. Thus, the
Agency estimates risk in terms of the probability of an occurrence of the adverse effect expected in a lifetime. For more information on the general principles EPA uses in risk characterization and a complete description of the risk assessment process, see http://www.epa.gov/pesticides/factsheets/riskassess.htm. A summary of the toxicological endpoints for novaluron used for human risk assessment is shown in
Table 1 of this unit.

Condition b: The exposure estimate does not underestimate exposure for any significant subpopulation group.
Condition c: Data are available on pesticide use and food consumption in a particular area, the exposure estimate does not understate exposure for the population in such area.
In addition, the Agency must provide for periodic evaluation of any estimates used. To provide for the periodic evaluation of the estimate of PCT as required by FFDCA section 408(b)(2)(F), EPA may require registrants to submit data on PCT.
The Agency estimated the PCT for existing uses as follows:
Apples at 15%; cabbage at 10%; cotton at 2.5%; pears at 10%; and potatoes at 2.5%.
In most cases, EPA uses available data from United States
Department of Agriculture/National Agricultural Statistics Service
(USDA/NASS), proprietary market surveys, and the National Pesticide Use
Database for the chemical/crop combination for the most recent 6-7 years. EPA uses an average PCT for chronic dietary risk analysis. The average PCT figure for each existing use is derived by combining available public and private market survey data for that use, averaging across all observations, and rounding to the nearest 5%, except for those situations in which the average PCT is less than one. In those cases, 1% is used as the average PCT and 2.5% is used as the maximum
PCT. EPA uses a maximum PCT for acute dietary risk analysis. The maximum PCT figure is the highest observed maximum value reported within the recent 6 years of available public and private market survey data for the existing use and rounded up to the nearest multiple of 5%.
The Agency estimated the PCT for new uses as follows:
Sweet corn at 59% and sorghum at 5%.
EPA utilized estimated PCT data in the chronic dietary risk assessment for the new use on sweet corn and sorghum, based on the market leader approach. Sorghum, though not new, was only registered 1 year ago. Since sorghum has been registered for such a relatively short period, EPA has sorghum to be a ``new use'' when estimating the PCT.
The market leader approach is the comparison of the PCT with all chemicals of a specific type (i.e., herbicide, insecticide, etc.) on a specific crop and choosing the highest PCT (market leader) as the PCT for the new use. This method of estimating a PCT for a new use of a registered pesticide or a new pesticide produces a high-end estimate that is unlikely, in most cases, to be exceeded during the initial 5 years of actual use. The predominant factors that bear on whether the estimated PCT could be exceeded are: The extent of the pest pressure on the crops in question; the pest spectrum of the new pesticide in comparison with the market leaders as well as whether the market leaders are well-established for this use; and resistance concerns with the market leaders.
Novaluron has a relatively narrow spectrum of activity compared to the market leaders. Additionally, there are no resistance or pest pressure issues identified for the use of novaluron on sweet corn. All information currently available has been considered for use on sweet corn, and EPA concludes that it is unlikely that the actual sweet corn
PCT with novaluron will exceed the estimated PCT for new uses during the next 5 years.
The Agency believes that the three conditions discussed in Unit
III.C.1.iv. have been met. With respect to Condition a, PCT estimates are derived from Federal and private market survey data, which are reliable and have a valid basis. The Agency is reasonably certain that the percentage of the food treated is not likely to be an underestimation. As to Conditions b and c, regional consumption information and consumption information for significant subpopulations is taken into account through EPA's computer-based model for evaluating the exposure of significant subpopulations including several regional groups. Use of this consumption information in EPA's risk assessment process ensures that EPA's exposure estimate does not understate exposure for any significant subpopulation group and allows the Agency to be reasonably certain that no regional population is exposed to residue levels higher than those estimated by the Agency. Other than the data available through national food consumption surveys, EPA does not have available reliable information on the regional consumption of food to which novaluron may be applied in a particular area. 2. Dietary exposure from drinking water. The residues of concern in drinking water are novaluron and its chlorophenyl urea and chloroaniline degradates. The Agency used screening level water exposure models in the dietary exposure analysis and risk assessment for novaluron in drinking water. These simulation models take into account data on the physical, chemical, and fate/transport characteristics of novaluron. 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.
Estimated drinking water concentrations (EDWCs) were not generated for the food-and-feed handling establishment uses because the use pattern is not expected to result in the contamination of drinking water. Based on the Pesticide Root Zone Model/Exposure Analysis
Modeling System (PRZM/EXAMS) for parent novaluron in surface water; and the Screening Concentration in Ground Water (SCI-GROW) models for novaluron, chlorophenyl urea and
Page 55811
chloroaniline in ground water, the EDWCs of novaluron, chlorophenyl urea, and chloroaniline for chronic exposures for non-cancer assessments are estimated to be 0.76 parts per billion (ppb), 0.89 ppb and 2.6 ppb, respectively, for surface water and 0.0056 ppb, 0.0045 ppb and 0.0090 ppb, respectively, for ground water.
Modeled estimates of drinking water concentrations were directly entered into the dietary exposure model. The highest drinking water concentrations were estimated for surface water. Of the three EDWC values for surface water, the chronic EDWC for the terminal metabolite chloroaniline, is the highest (assuming 100% molar conversion from parent to aniline). This is consistent with the expected degradation pattern for novaluron. Therefore, for chronic dietary risk assessment, the water concentration value for chloroaniline of 2.6 ppb was used to assess the contribution to drinking water. 3. From non-dietary exposure. The term ``residential exposure'' is used in this document to refer to non-occupational, non-dietary exposure (e.g., for lawn and garden pest control, indoor pest control, termiticides, and flea and tick control on pets). Novaluron is not currently registered for any specific use patterns that would result in residential exposure. However, the following uses that could result in residential exposures are pending registration and have been assessed:
Indoor and outdoor uses for the control of roaches and crickets (crack and crevice and spot treatments) in residential areas such as homes and apartment buildings, and their immediate surroundings, and on modes of transportation.
There is a potential for exposure in residential settings during the application process for homeowners who use products containing novaluron. There is also a potential for exposure from entering novaluron-treated areas that could lead to exposures to adults and children. Both residential handler and post-application scenarios were assessed for the indoor use since this is believed to cover the outdoor perimeter treatment. Residential handler dermal and inhalation exposures were assessed for application via low-pressure handwands and trigger-pump sprayers.
Additionally exposure routes were assessed for post-application exposures for adults and children via inhalation and dermal routes and post-application incidental oral (hand-to-mouth) exposure for children
(3 to 5,000 mg/kg).
Therefore, novaluron does not appear to be a neurotoxicant, and there is no need for a developmental neurotoxicity study or additional UFs to account for neurotoxicity. iii. There is no evidence that novaluron results in increased susceptibility in in utero rats or rabbits in the prenatal developmental studies or in young rats in the 2-generation reproduction study. iv. There are no residual uncertainties identified in the exposure databases. The dietary food exposure assessments were performed using anticipated residues derived from reliable residue field trials and PCT assumptions for some commodities. EPA made conservative (protective) assumptions in the ground and surface water modeling used to assess exposure to novaluron in drinking water. EPA used similarly conservative assumptions to assess postapplication exposure of children as well as incidental oral exposure of toddlers resulting from the proposed residential uses of novaluron. These assessments will not underestimate the exposure and risks posed by novaluron.
-
Aggregate Risks and Determination of Safety
EPA determines whether acute and chronic dietary pesticide exposures are safe by comparing aggregate exposure estimates to the acute PAD (aPAD) and chronic PAD (cPAD). For linear cancer risks, EPA calculates the lifetime probability of acquiring cancer given the estimated aggregate exposure. Short-, intermediate-, and chronic-term risks are evaluated by comparing the estimated aggregate food, water, and residential exposure to the appropriate PODs to ensure that an adequate MOE exists. 1. Acute risk. An acute aggregate risk assessment takes into account acute exposure estimates from dietary consumption of food and drinking water. No adverse effect resulting from a single oral exposure was identified and no acute dietary endpoint was selected. Therefore, novaluron 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 novaluron from food and water will utilize 72% of the cPAD for children 1 to 2 years old, the population group receiving the greatest exposure.
The residential exposure assessment was conducted using high-end estimates of use and potential exposure providing a conservative, health protective estimate of risk. 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).
There are potential short-term exposures from the pending residential uses for novaluron. The Agency has determined that it is appropriate to aggregate chronic exposure through food and water with short-term residential exposures to novaluron.
Using the exposure assumptions described in this unit for short- term exposures, EPA has concluded the combined short-term food, water, and residential exposures result in aggregate MOEs of 1,600 for the
U.S. population and 290 for children 1-2 years old. Because EPA's level of concern for novaluron is a MOE of 100 or below, these MOEs are not of concern. 4. Intermediate-term risk. Intermediate-term aggregate exposure takes into account intermediate-term residential exposure plus chronic exposure to food and water (considered to be a background exposure level).
There are potential intermediate-term exposures from the pending residential uses for novaluron. The Agency has determined that it is appropriate to aggregate chronic exposure through food and water with intermediate-term residential exposures to novaluron.
Using the exposure assumptions described in this unit for intermediate-term exposures, EPA has concluded that the combined intermediate-term food, water, and residential exposures result in aggregate MOEs of 320 for U.S. population and 140 for children 1-2 years old. Because EPA's level of concern for novaluron is a MOE of 100 or below, these MOEs are not of concern. 5. Aggregate cancer risk for U.S. population. Based on the lack of evidence of carcinogenicity in two adequate rodent carcinogenicity studies, novaluron is not expected to pose a cancer risk to humans. 6. Determination of safety. Based on these risk assessments, EPA concludes that there is a reasonable certainty that no harm will result to the general population, or to infants and children from aggregate exposure to novaluron residues.

Analytical Enforcement Methodology
The following adequate enforcement methodologies (gas chromatography/electron-capture detection (GC/ECD) method and a high- performance liquid chromatography/ultraviolet (HPLC/UV) method) are available to enforce the tolerance expression. The methods 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: residuemethods@epa.gov.

International Residue Limits
In making its tolerance decisions, EPA seeks to harmonize U.S. tolerances with international standards whenever possible, consistent with U.S. food safety standards and agricultural practices. EPA considers the international maximum residue limits (MRLs) established by the Codex Alimentarius Commission (Codex), as required by FFDCA section 408(b)(4). The Codex Alimentarius is a joint U.N. Food and
Agriculture Organization/World Health Organization food standards program, and it is recognized as an international food safety standards-setting organization in trade agreements to which the United
States is a party. EPA may establish a tolerance that is different from a Codex MRL; however, FFDCA section 408(b)(4) requires that EPA explain the reasons for departing from the Codex level.
There are no Codex, Canadian, or Mexican maximum residue limits
(MRLs) established for residues of novaluron in or on sweet corn, stover,
Page 55813
forage and kernel plus cob with husks removed or for all food commodities based on the use of novaluron in food and feed handling establishments. Canada is currently in the process of reviewing the use of novaluron on sweet corn. The EPA and the Pest Management Regulatory
Agency (PMRA) reviewed the sweet corn petition as a Joint Review
Project and tolerance recommendations are in agreement at 0.05 ppm for sweet corn and kernel plus cob with husks removed. Additionally, PMRA proposed to increase its MRL for milk to 1.0 ppm from 0.5 ppm, and as a result the EPA and PMRA milk tolerances/MRLs will be in agreement. The
PMRA does not recommend MRLs for livestock feed commodities and therefore will not establish MRLs for sweet corn stover and sweet corn forage.
-
Response to Comments
EPA received one comment to the Notice of Filing that made a general objection to the presence of any novaluron residues on vegetable crops. The Agency understands the commenter's concerns and recognizes that some individuals believe that pesticides should be banned on agricultural crops. However, the existing legal framework provided by section 408 of the Federal Food, Drug and Cosmetic Act
(FFDCA) states that tolerances may be set when persons seeking such tolerances or exemptions have demonstrated that the pesticide meets the safety standard imposed by that statute. This citizen's comment appears to be directed at the underlying statute and not EPA's implementation of it; the citizen has made no contention that EPA has acted in violation of the statutory framework. The commenter also expressed concern that EPA's risk assessment for novaluron did no ``combined testing'' with other chemicals. EPA, however, does not require
``combined testing'' of a pesticide with other pesticides or other chemicals due to impracticality. With regard to the potential for cumulative effects from exposure to the pesticide and other substances with a common mechanism of toxicity, see the discussion of this issue in Unit III.C.4., Cumulative effects from substances with a common mechanism of toxicity.
-
Revisions to Petitioned-for Tolerances
Based on analysis of the residue field trial data using the
Agency's Tolerance Spreadsheet in accordance with the Agency's Guidance for Setting Pesticide Tolerances Based on Field Trial Data, EPA revised the proposed tolerance on corn, sweet, forage from 20 ppm to 16 ppm and determined no change to the existing milk and milk fat tolerances is needed.
Based on the proposed use on sweet corn, the revised reasonably balanced dietary burdens (RBDBs) for novaluron are 9.6 ppm for beef cattle, 18.3 ppm for dairy cattle, 2.4 ppm for poultry, and 2.5 ppm for swine. Accordingly, the Agency has determined it is appropriate to raise the existing tolerances for meat byproducts. However, no changes are necessary for the tolerances for secondary residues in/on cattle, goat, horse, sheep, poultry, and swine commodities. Additionally, commodity terms for hog, meat byproducts and poultry, meat byproducts are being revised.
Therefore, the tolerances for meat byproducts are being revised as follows: Cattle, meat byproducts, except kidney and liver from 0.60 ppm to 11 ppm; goat, meat byproducts, except kidney and liver from 0.60 ppm to 11 ppm; horse, meat byproducts, except kidney and liver from 0.60 ppm to 11 ppm; sheep, meat byproducts, except kidney and liver from 0.60 ppm to 11 ppm; hog, meat byproducts from 0.10 ppm to hog, meat byproducts, except kidney and liver to 1.5 ppm; and poultry, meat byproducts from 0.80 ppm to poultry, meat byproducts, except kidney and liver to 7.0 ppm.

-
Conclusion
Therefore, tolerances are established for residues of novaluron,
(N-[3-chloro-4-[1,1,2-trifluoro-2- (trifluoromethoxy)ethoxy] phenyl]amino]carbonyl]-2,6-difluorobenzamide), in or on corn, sweet, kernels plus cob with husks removed at 0.05 ppm; corn, sweet, forage at 16 ppm; corn, sweet, stover at 50 ppm; cattle, meat byproducts, except kidney and liver at 11 ppm; goat, meat byproducts, except kidney and liver at 11 ppm; horse, meat byproducts, except kidney and liver at 11 ppm; sheep, meat byproducts, except kidney and liver at 11 ppm; hog, meat byproducts, except kidney and liver at 1.5 ppm; poultry, meat byproducts, except kidney and liver at 7.0 ppm; and Food/feed commodities (other than those covered by a higher tolerance as a result of use on growing crops) in food/feed handling establishments at 0.01 ppm.

Statutory and Executive Order Reviews
This final rule establishes tolerances 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 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 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 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) (Pub. L. 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

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).
