1.0	Executive Summary

Chlorantraniliprole is an anthranilic diamide insecticide that belongs to a class of compounds that acts on the ryanodine receptor (RyR).  It was developed and registered by E.I. du Pont de Nemours and Company (DuPont) to control lepidopteran pests and insects primarily via interruption of normal muscle contraction pathways, leading to paralysis and eventual death. However, the relative absence of mammalian hazard following chlorantraniliprole exposure may be due in part to chlorantranilprole's selectivity for insect RyR over mammalian counterparts.  

There are five proposed chlorantraniliprole registration actions evaluated in this risk assessment:

   1. D410513 - E.I. du Pont de Nemours and Company (DuPont) has requested a Section 3 registration and tolerances of chlorantraniliprole on peanuts. 
   2. D412169  -  The Interregional Research Project No. 4 (IR-4) of Rutgers University has requested crop group conversions for existing tolerances on the stone fruit and tree nut crop groups to correspond with the crop group commodities update in 2012.  
   3. D412173  -  The IR-4 has requested to shorten the existing pre-harvest intervals (PHIs) for papaya, passionfruit, and mayhaw.  Additionally, IR-4 has requested to delete the existing separate mayhaw tolerance because mayhaw will be supported by the existing pome fruit tolerance (crop group 11-10).  
   4. D412170  - The IR-4 requested to add greenhouse use directions to the existing chlorantraniliprole labels for fruiting vegetables and cucurbits.  The existing cucumber and tomato data will support the addition of greenhouse use directions on the labels for greenhouse tomato, pepper, and cucumber; there is no request for tolerances. 
   5. D412717  -  The IR-4 has requested chlorantraniliprole use and tolerances on green onion (crop subgroup 3-07B) and requested to raise the existing tolerance for spice subgroup 19B based on data on green onion and dill.  

Concomitant with these petitions, condition of registration field trial data were submitted for rice, coffee, and strawberry; these data confirm the existing tolerances.  Additionally, a study submitted as confirmatory data for crayfish supports lowering the current crayfish tolerance. Condition of registration residue decline data on cherry, papaya, and lychee were also submitted to support existing tolerances for certain tropical fruits and to propose lowering the PHIs from 10 days to 1 day, with a tolerance increase of 2 ppm to 4 ppm for papaya and passionfruit.  The new data for dried onions combined with previous data for alfalfa hay translated to dried basil support retention of the 90 ppm tolerance for herb subgroup 19A.  

Permanent tolerances are currently established in 40 CFR §180.628 for chlorantraniliprole in/on a variety of commodities.

Use Profile
The end-use product (EP) formulations relevant to these requests are a 5% active ingredient (ai) suspension concentrate (SC), Prevathon[(R)] Insect Control (0.43 lb ai per gallon, or 0.053 kg ai/l), EPA Reg. No. 352-844; a 18.4% ai SC, Coragen[(R)] Insect Control (1.67 lb ai/gallon or 0.200 kg ai/l), EPA Reg. No. 352-729; a 35.0% ai water dispersible granular (WDG), Altacor(R) (35 lb ai/100 lb) EPA Reg. No. 352-730; and a 50% ai Flowable Concentrate (FC), Dermacor(R) X-100 Seed Treatment (FS, 5.210 lb ai/gal), EPA Reg No. 352-820).  Chlorantraniliprole may be applied via drip irrigation, ground, handheld, seed treatment, and aerial application methods.  Chlorantraniliprole is also registered for use in residential settings on turf, landscape ornamentals, and interiorscapes.  Chlorantraniliprole may also be used on golf courses and sod farms. 

Exposure Profile 
There is a potential for occupational short- and intermediate-term inhalation and dermal exposure to chlorantraniliprole during mixing, loading, application, and post-application activities.  There is potential for short-term exposure from the registered residential uses on turf, golf courses landscape ornamentals, and interiorscapes.  There is also exposure expected through food and drinking water from the proposed and registered uses of chlorantraniliprole.

Hazard Characterization
There is sufficient toxicology information for selecting doses and endpoints for chlorantraniliprole risk assessment.  In short-term studies, the most consistent effects are those associated with non-adverse induction of liver enzymes and subsequent increase in liver weights.  Increased microvesiculation of the adrenal cortex was observed in several rat studies; however detailed histopathology and a special adrenal function study found no adverse adrenal effects in the rat.   There was only one animal toxicity study (18-month carcinogenicity study in mice) in the database that produced adverse effects following chlorantraniliprole exposure.  Chlorantraniliprole is not considered developmentally toxic, genotoxic, neurotoxic, immunotoxic, or carcinogenic.  A subchronic inhalation toxicity study is not required for chlorantraniliprole at this time.  Chlorantraniliprole is classified as Acute Toxicity Category IV for acute oral, dermal, and inhalation toxicity; acute eye irritation; and primary skin irritation.  Chlorantraniliprole is not a dermal sensitizer.  Based on the available hazard and exposure data, the Food Quality Protection Act (FQPA) Safety Factor (SF) is reduced to 1x for all population subgroups and exposure scenarios.  

Dietary Risk Estimates (Food and water)
An acute dietary risk assessment was not performed because there was no acute hazard attributable to a single dose identified in the chlorantraniliprole toxicity database.  

The chronic dietary (food and drinking water) exposure assessment is considered conservative and assumed tolerance-level residues and that 100% of the proposed and registered crops were treated with chlorantraniliprole (100%CT).  Where processing data indicated a reduction (or no increase) in residue upon processing, the residue level of the raw agricultural commodity (RAC) was used without reduction.  Where processing data indicated an increase in residue in the processed commodity, a tolerance was established and used, e.g., raisins from grapes.  Where adequate processing data did not exist, default concentration factors were used if available.  Estimated drinking water concentrations (EDWCs) from ground water from the Environmental Fate and Effects Division (EFED) were also included.  The results of the chronic analysis indicate that the chronic dietary (food and drinking water) risk estimates utilized 2.3% of the chronic population adjusted dose (cPAD) for the general U.S. population and utilized 6.7% of the cPAD for children 1-2 years old, the most highly exposed population subgroup.  Therefore, the chronic dietary risk is not of concern (i.e., <100% of the cPAD).  

Aggregate Risk
Short- and intermediate-term aggregate risk assessments were not performed because there was no hazard identified over short- or intermediate-term durations.  Therefore, the aggregate risk assessment for chlorantraniliprole only includes chronic exposures to residues in food and drinking water.  The chronic dietary risk assessments for the U.S. population and all population subgroups are not of concern to HED (<100% cPAD).

Occupational Risk
Although there is potential for occupational handler and post-application exposure, the chlorantraniliprole toxicology database indicates there is no systemic hazard associated with short- and intermediate-term dermal and inhalation exposure, and therefore, no quantitative occupational exposure and risk assessment was conducted.

Environmental Justice
Potential areas of environmental justice concerns, to the extent possible, were considered in this human health risk assessment, in accordance with U.S. Executive Order 12898, "Federal Actions to Address Environmental Justice in Minority Populations and Low-Income Populations," http://www.eh.doe.gov/oepa/guidance/justice/eo12898.pdf).

2.0	Regulatory Conclusions and Recommendations

HED has examined the residue chemistry, toxicity, and exposure databases for chlorantraniliprole and concluded that, provided a revised Section F is submitted, there are no deficiencies that would preclude granting a Section 3 registration on peanuts and green onion subgroup 3-07B; adding the greenhouse use directions for fruiting vegetables and cucurbits; and granting the requested crop group conversions.  A crayfish tolerance of 8 ppm was previously established based on a fish bioconcentration study and the estimated residues in water, sediment, and rice straw. The present crayfish study showed no residues (<0.01 ppm) at various sampling intervals from the use of chlorantraniliprole as a seed treatment on rice.   This reflects the actual use pattern. Therefore, a tolerance of 0.01 ppm is more appropriate and a modified Section F is required.

The specific tolerance recommendations are discussed in Section 2.2.3.  

2.1	Data Deficiencies/Conditions of Registration

There are no data deficiencies associated with the proposed uses of chlorantraniliprole.

2.2	Tolerance Considerations

2.2.1	Enforcement Analytical Method

An adequate enforcement method (liquid chromatography/tandem mass spectrometry (LC/MS/MS), DuPont-11374) is available for the determination of chlorantraniliprole residues in/on plant commodities.  The limit of quantitation (LOQ) is reported at 0.01 ppm for parent chlorantraniliprole.  The method for the determination of chlorantraniliprole and its metabolites in processed commodities is a LC/MS/MS method, DuPont-14314, which is a slightly modified version of DuPont-11374.  These methods have been accepted by the Analytical Chemistry Branch (ACB)/Biological and Economical Analysis Division (BEAD; C. Stafford, D340358, 02/06/2008).

An adequate enforcement method (LC/MS/MS) is available for the determination of residues of chlorantraniliprole and its metabolites in/on animal commodities.  Atmospheric pressure chemical ionization (APCI) MS/MS detection operated in the positive ion mode is used.  The LOQ is reported at 0.010 ppm for the parent and each of the metabolites.  The method has been accepted by ACB/BEAD (C. Stafford, D340358, 02/06/2008).

2.2.2	International Harmonization

Residue definitions are harmonized among the US, Canada, and Codex, with the common definition chlorantraniliprole.   

The existing US tolerance for the tree nut group is 0.04 ppm, whereas the tolerance in both Canada and Codex is 0.02 mg/kg.  The US tolerance is based upon the evaluation of field trial data for pecans and almonds with the use of the North American Free Trade Agreement (NAFTA) statistical spreadsheet (N. Tsaur, D357727, 03/03/2009).  The data were reevaluated using the Organization for Economic Cooperation and Development (OECD) tolerance calculation procedures.  The new tolerance estimate is 0.02 ppm.  Therefore, the tolerance for tree nuts, including pistachio, is lowered to 0.02 ppm, and harmonization with Canada and Codex is achieved.

The existing US tolerance for the pome fruit group is 1.2 ppm.  The Codex maximum residue limit (MRL) for pome fruit is 0.4 ppm, and the Canada MRL for various pome fruits (apple, pear, mayhaw, and quince) is 0.4 ppm.  The original US tolerance for pome fruits was 0.3 ppm, but it was adjusted upwards to 1.2 ppm to accommodate the use of adjuvants and a shortened PHI (D. Rate, D361791, 01/08/2010).  Therefore, the 1.2 ppm value cannot be lowered to harmonize with Codex and/or Canada.

The existing US tolerance for the stone fruit group (except cherry, chickasaw plum, and damson plum) is 4.0 ppm.  The Codex MRL for stone fruits is 1 mg/kg and the Canada MRL for various stone fruits (apricot, nectarine, peach, plum, plumcots, and cherries) is 2.5 mg/kg.  The original US tolerance for stone fruits was 1.0 ppm, but it was adjusted upwards to 4.0 ppm to accommodate the use of adjuvants and a shortened PHI (D. Rate, D361791, 01/08/2010).  Therefore, the 4.0 ppm value cannot be lowered to harmonize with Codex and/or Canada.

Codex has not established MRLs for passionfruit, papaya, peanuts, green onions, herbs, or spices.  Therefore, there is no harmonization issue with Codex.  Canada does not have MRLs for these same commodities, with the exception of green onions and peanuts.  Canada and the US are conducting a joint review for green onions and peanuts and will work to harmonize the MRLs.

2.2.3	Recommended Tolerances

The current tolerance definition is found at 40CFR§180.628.  Compliance with the tolerance is based on measuring only chlorantraniliprole for both plant and animal commodities.

[1] A tolerance of 14 ppm was recommended (D361791, D. Rate, 01/08/2010), but is not listed in 40CFR§180.628.  This was based on the translation of alfalfa seed data, with adjustments for adjuvant use (2x) and application rate (2x).

2.2.4	Revisions to Petitioned-For Tolerances

The petitioned tolerances are the same as the recommended tolerances, except for spice subgroup 19B, crayfish, and increased/decreased tolerances for the crop group conversions due to international harmonization.  

Residue data on dill seed was presented in support of a spice subgroup 19B tolerance.  HED had previously recommended for a spice subgroup 19B tolerance of 14 ppm.  The petitioner requested 40 ppm, but evaluation of the dill seed data indicates that 90 ppm is appropriate.  Condition of registration data on field trial residue decline for cherry, papaya, and leechee support existing tolerances for certain tropical fruits and allow for lowering of the PHIs from 10 days to 1 day, with an increase in tolerance from 2 ppm to 4 ppm, for papaya and passionfruit.

A crayfish tolerance of 8 ppm was previously established based on a fish bioconcentration study and the estimated residues in water, sediment, and rice straw. The present crayfish study showed no residues (<0.01 ppm) at various sampling intervals from the use of chlorantraniliprole as a seed treatment on rice.  This reflects the actual use pattern. A tolerance of 0.01 ppm is appropriate.  A modified Section F is required.

A crop group conversion for tree nut group 14 to tree nut group 14-2 was requested.  This is acceptable, but the tolerance will be changed from 0.04 ppm to 0.02 ppm to harmonize with Canada and Codex.

The registrant must submit a revised Section F requesting tolerances of 90 ppm and 0.01 ppm for the spice subgroup 19B and crayfish, respectively.

2.3	Label Recommendations

There are no label recommendations for this petition. 

3.0	Introduction

The ai, chlorantraniliprole, is an anthranilic diamide insecticide that belongs to a class of compounds that acts on the RyR.  It was developed and registered by E.I. du Pont de Nemours and Company (DuPont) to control lepidopteran pests and insects primarily via interruption of normal muscle contraction pathways, leading to paralysis and eventual death.

3.2	Physical/Chemical Characteristics

The physical/chemical properties of chlorantraniliprole are summarized in Appendix B.  Based on the low vapor pressure (6.3 x 10[-12] Pa at 20º C) and KOW (~3 at pH ranges 4 to 9), chlorantraniliprole is not expected to volatilize, pass lipid barriers (consistent with dermal absorption findings in mammals), or bioaccumulate.  Environmental fate data indicate chlorantraniliprole is persistent and mobile in terrestrial and aquatic environments.  Major routes of chlorantraniliprole dissipation are expected to be alkaline-catalyzed hydrolysis, photodegradation in water, leaching, and runoff.  

3.3	Pesticide Use Pattern

For the proposed Section 3 registrations addressed herein there are four EPs, two SCs, one FC, and one WDG.  The proposed changes will also apply to the technical product label (EPA Reg. No. 352-728).  Proposed labels have been provided for a 5% ai SC, Prevathon(R) Insect Control (0.43 lb ai per gallon, or 0.053 kg ai/l) EPA Reg. No. 352-844; a 18.4% ai SC, Coragen[(R)] Insect Control (1.67 lb ai/gallon or  0.200 kg ai/l) EPA Reg. No. 352-729; a 35% ai WDG, Altacor(R) (35 lb ai/100 lb) EPA Reg. No. 352-730; and a 50% ai Flowable Concentrate (FC) Dermacor(R) X-100 Seed Treatment (FS, 5.210 lb ai/gal), EPA Reg No. 352-820).  Changes to the Altacor(R) label involve only crop conversions, and changes to Dermacor(R) only involves the conditional data related to seed treatment use on rice.  The WDG formulation is not proposed for use on cereal grains.  The summary of the relevant proposed uses is presented in Table 3.3.

3.4	Anticipated Exposure Pathways

Humans may be exposed to chlorantraniliprole in food and drinking water, since chlorantraniliprole may be applied directly to growing crops and application may result in chlorantraniliprole reaching surface and ground water sources of drinking water.  There are registered residential uses of chlorantraniliprole, so there is likely to be exposure in residential or non-occupational settings.  In an occupational setting, applicators may be exposed while handling the pesticide prior to application, as well as during application.  There is a potential for post-application exposure for workers re-entering treated fields.

This risk assessment considers all of the aforementioned exposure pathways based on the proposed new uses of chlorantraniliprole, but also considers the existing uses as well, particularly for the dietary assessment.

3.5	Consideration of Environmental Justice

Potential areas of environmental justice concerns, to the extent possible, were considered in this human health risk assessment, in accordance with U.S. Executive Order 12898, "Federal Actions to Address Environmental Justice in Minority Populations and Low-Income Populations," http://www.epa.gov/environmentaljustice/resources/policy/exec_order_12898.pdf.  As a part of every pesticide risk assessment, OPP considers a large variety of consumer subgroups according to well-established procedures.  In line with OPP policy, HED estimates risks to population subgroups from pesticide exposures that are based on patterns of that subgroup's food and water consumption, and activities in and around the home that involve pesticide use in a residential setting.  Extensive data on food consumption patterns are compiled by the U.S. Department of Agriculture's National Health and Nutrition Examination Survey, What We Eat in America, (NHANES/WWEIA) and are used in pesticide risk assessments for all registered food uses of a pesticide.  These data are analyzed and categorized by subgroups based on age and ethnic group.  Additionally, OPP is able to assess dietary exposure to smaller, specialized subgroups and exposure assessments are performed when conditions or circumstances warrant.  Whenever appropriate, non-dietary exposures based on home use of pesticide products and associated risks for adult applicators and for children 1-2 years, youths, and adults entering or playing on treated areas post-application are evaluated.  Further considerations are currently in development as OPP has committed resources and expertise to the development of specialized software and models that consider exposure to bystanders and farm workers as well as lifestyle and traditional dietary patterns among specific subgroups.

4.0	Hazard Characterization and Dose-Response Assessment

No new toxicity and/or metabolism data have been received since the last risk assessment.  This assessment includes summaries of prior assessments (S. Healy, D399493, 05/17/2012).  The Hazard and Science Policy council waived the required subchronic inhalation toxicity study (TXR#0056851).  

4.1	Summary of Toxicological Effects

Chlorantraniliprole is an anthranilic diamide insecticide that belongs to a class of compounds that acts on the RyR.  It controls lepidopteran pests and insects primarily via interruption of normal muscle contraction pathways, which leads to paralysis and eventual death.  The relative absence of mammalian hazard may be due in part to chlorantranilprole's selectivity for insect RyR over mammalian counterparts.  In short-term mammalian studies, the most consistent effects are increased liver weights and mild induction of liver enzymes.  In oral and dermal toxicity studies in rats, increased incidence of adrenal cortex microvesiculation was observed (usually in males only). However, an additional special study to assess the capacity of the adrenal gland to produce corticosterone found no effects in male rats (with or without microvesiculation) following ACTH stimulation. Therefore, adrenal cortex microvesiculation observed in rat studies was not considered adverse.  Chlorantraniliprole does not exhibit pre- or postnatal toxicity as there were no maternal or fetal effects in studies conducted in rats and rabbits.  Chlorantraniliprole is not genotoxic, neurotoxic, immunotoxic, carcinogenic, or developmentally toxic.  Chlorantraniliprole is classified as "Not likely to be Carcinogenic to Humans".  No treatment-related tumors were reported in the submitted chronic and oncogenicity studies in rats and mice (18-month carcinogenicity study) or in the subchronic studies in mice, dogs and rats.

Based on the results of short-term and acute dermal studies, chlorantraniliprole has relatively low dermal toxicity.  Chlorantraniliprole is not acutely toxic via the oral, or inhalation routes of exposure.  The LD50 for both oral and dermal acute exposure is > 5000 mg/kg/day and the LC50 for acute inhalation exposure is > 5.1 mg/L.  Chlorantraniliprole is not an eye or skin irritant and does not cause skin sensitization.  The acute inhalation study did not report any portal of entry effects or acute irritation via the inhalation route of exposure.  

Absorption, Distribution, Metabolism, Excretion (ADME)
Chlorantraniliprole metabolism was studied extensively in rats, mice, and dogs.  In rats, absorption of chlorantraniliprole was rapid with peak concentrations occurring at 5-12 hours after low or high (10 or 200 mg/kg) oral single dose administration.  The plasma elimination half-lives after single dose ranged from 41 hours in males to 79 hours in female rats.  Tissue distribution of the absorbed dose was extensive and indicated low potential for accumulation.  The tissue residues were higher in female rats than in male rats, which is consistent with female rats having a longer elimination half-life.  Rapid excretion was observed via bile (49-53%) within 48 hours and 88-97% total excretion was observed within 7 days after single or multiple doses.  Fecal excretion was the primary route of elimination followed by excretion in the urine with no significant excretion occurring by exhalation.  Metabolism of the absorbed dose was extensive and involved sex differences (greater hydroxylation in males).  Results also suggest possible species differences in the primary metabolites formed in all three species tested.  Metabolites represented in the rat metabolism cascade were: IN-K9T00, IN-HXH44, IN-KAA24, IN-H2H20, and IN-GAZ70 (chemical nomenclature and molecular structures for these compounds can be found in:  S. Healy, D381810, 02/28/2011).

Based on studies conducted in rats, dermal penetration of chlorantraniliprole formulations is approximately <= 1.09% for undiluted concentrates and 2.10-2.79% for 0.75 g/L aqueous dilutions of the concentrates.

4.2	Safety factor for Infants and Children (FQPA Safety Factor)

Based on the hazard and exposure data, the HED chlorantraniliprole risk assessment team recommends that the FQPA SF be reduced to 1x.  The rationale for this recommendation is provided in the following sections.

4.2.1	Completeness of the Toxicology Database

The toxicity database for this chemical is complete for the purposes of this risk assessment and considered adequate for the characterization of potential pre- and post-natal risks to infants and children.  Acceptable developmental toxicity, 2-generation reproduction toxicity, acute neurotoxicity, subchronic neurotoxicity, and immunotoxicity studies have been submitted and reviewed. The Hazard and Science Policy council waived the required subchronic inhalation toxicity study based on chlorantraniliprole's physical chemical properties, including low vapor pressure; low acute inhalation toxicity (Toxicity Category IV); and the use of a conservative, chronic oral POD that results in screening-level MOEs >12,000 (TXR#0056851).  

4.2.2	Evidence of Neurotoxicity

There is no indication that chlorantraniliprole is a neurotoxic chemical and there is no need for a developmental neurotoxicity study or additional uncertainty factors (UFs) to account for neurotoxicity.  The no observed adverse effect level (NOAEL) in an acute oral gavage neurotoxicity study was 2000 mg/kg, the limit dose.  In a subchronic neurotoxicity study, the NOAEL was 1313/1586 mg/kg/day (M/F), the maximum dietary concentration administered (greater than the limit dose).  The NOAELs were based on the absence of treatment related effects on systemic toxicity and neurotoxicity parameters, including microscopic neuropathology.  Neurological assessments conducted in conjunction with the 18-month oncogenicity study in mice following 45, 60, and 90 days of dietary administration of chlorantraniliprole confirmed the lack of potential neurotoxicity.  Further, no treatment related clinical signs indicative of potential neurotoxicity were observed in short-term or long-term exposure studies in rats, mice, or dogs.  

4.2.3	Evidence of Sensitivity/Susceptibility in the Developing or Young Animal

There is no evidence that chlorantraniliprole 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.  There were no effects on prenatal fetal growth or postnatal development up to the limit dose of 1000 mg/kg/day in rats or rabbits.  There were no treatment-related effects on the numbers of litters, fetuses (live or dead), resorptions, sex ratio, or post-implantation loss.  There were no effects on fetal body weights; skeletal ossification; and external, visceral, or skeletal malformations or variations.  

4.2.4	Residual Uncertainty in the Exposure Database

There are no residual uncertainties identified in the exposure databases. The chronic dietary assessment utilized tolerance-level residues for all crops and assumed 100% CT of the proposed and registered crops were treated with chlorantraniliprole.  Where processing data indicated a reduction (or no increase) in residue upon processing, the residue level of the RAC was used without reduction.  Where processing data indicated an increase in residue in the processed commodity, a tolerance was established and used, e.g., raisins from grapes.  Where adequate processing data did not exist, default concentration factors were used if available.  EPA made conservative (protective) assumptions in the ground and surface water modeling used to assess exposure to chlorantraniliprole in drinking water. Moreover, there is a lack of toxicity via the dermal route, as well as the lack of toxicity over the acute-, short- and intermediate-term via the oral route. These assessments will not underestimate the exposure and risks posed by chlorantraniliprole.

4.3	Toxicity Endpoint and Point of Departure Selections

The details for selecting toxicity endpoints and points of departure for various exposure scenarios are presented in the original risk assessment for Section 3 Registration (S. Winfield, DP336983, 03/07/2008).  There have been no changes to the prior dose-response assessment or recommendations for combining routes of exposure and/or cancer classification.  Refer to Table 4.3.1.

5.0	Dietary Exposure and Risk Assessment

5.1	Residues of Concern Summary and Rationale

The residues of concern for tolerance enforcement and risk assessment in plants, livestock, and water are summarized below in Table 5.1.  See Appendix B for names and structures.  HED also recalculated the dietary burdens for beef and dairy cattle (S. Funk, D416101, 11/12/2013).  The resulting residue estimates were below the established tolerances for ruminants; therefore, tolerance-levels were used in the dietary risk assessment for cattle.

5.2	Food Residue Profile

The submitted magnitude of the residue data are adequate for risk assessment and tolerance assessment.  For all crops, the number and locations of field trials are adequate.  Greenhouse tomato, greenhouse pepper, greenhouse cucumber, rice, coffee, and strawberry trials reflect the proposed label maximum application rate and other conditions and demonstrate that the existing tolerances are adequate.  The crayfish trials show that the existing tolerance may be reduced.  Residues in passionfruit, papaya, and mayhaw will increase with decreased PHIs, but the existing respective group tolerances are protective.  Trials for proposed uses on green onions and peanuts are adequate both in number of trials and geographic distribution and are conducted under conditions reflective of the proposed labels.  The new feed item, peanut hay, does not increase the calculated dietary exposure of ruminants and therefore does not change the existing tolerances for ruminant commodities. The dill seed trials provide a tolerance estimate of 90 ppm for the spices subgroup 19B.  This is an increase from the previous recommendation of 14 ppm, and the registrant request for 40 ppm.  The new data for dried onions combined with previous data for alfalfa hay translated to dried basil support retention of the 90 ppm for herb subgroup 19A.  The field trial studies are supported by adequate storage stability data.

The existing cotton seed processing study is translated to peanut, and no concentration of residue occurs in the oil or meal.   

Adequate confined and limited field rotational crop data are available.  HED previously concluded that the residue of concern in rotational crops is parent only.  All necessary rotational crop tolerances were established previously or appropriate label restrictions were implemented.   Several inadvertent tolerances will now be replaced with primary crop commodity tolerances.  Extensive primary crop or crop group tolerances have been established, and therefore there are very few inadvertent tolerances needed.



5.3	Water Residue Profile

The EDWC for groundwater from the assessment evaluating the proposed uses is greater than the surface and groundwater estimates from the previous assessment.  Thus, the groundwater concentration of 207 ppb (one-in-ten-year annual mean) based on the Wisconsin corn scenario was used in the dietary exposure assessment (C. Koper, D414839, 09/23/2013).

5.4	Dietary Risk Assessment

5.4.1	Description of Residue Data Used in Dietary Assessment

HED used tolerance-level residues for the proposed and registered crops and 100% crop treated was assumed for all commodities included in this assessment; therefore, this assessment is considered conservative.  Where processing data indicated a reduction (or no increase) in residue upon processing, the residue level of the RAC was used without reduction, for example mint oil from spearmint.  Where processing data indicated an increase in residue in the processed commodity, a tolerance was established and used, e.g., raisins from grapes.  Where adequate processing data did not exist, default concentration factors were used if available.  Default concentration factors were used for the following:  dried apple, apple juice, dried apricot, dried banana, dried beef meat, cherry juice, field corn syrup, cranberry juice, grape juice, grapefruit juice, lemon juice, lime juice, dried lychee, dried (dehydrated) bulb onion, orange juice, dried peach, dried pear, peanut butter, dried pineapple, pineapple juice, dried plantain, dried plum prune, plum juice, dried potato (flakes, granules), potato flour, tangerine juice, tomato paste, tomato puree, dried tomato, and tomato juice.  

The drinking water residues used in the dietary risk assessment were provided by EFED (C. Koper, D414839, 09/23/2013) and incorporated directly into this dietary assessment.  Water residues were incorporated in the Dietary Exposure Evaluation Model software with the Food Commodity Intake Database (DEEM-FCID(TM)) into the food categories "water, direct, all sources" and "water, indirect, all sources."  The estimated groundwater concentration of 207 ppb was used for this assessment.  




5.4.2	Acute Dietary Risk Assessment

No acute dietary toxicity endpoint could be identified based on the toxicology data currently available for chlorantraniliprole; therefore, an acute assessment was not performed.  

5.4.3	Chronic Dietary Risk Assessment

The results of the chronic analysis indicate that the chronic dietary (food and drinking water) risk estimates utilized 2.3% of the cPAD for the general U.S. population and utilized 6.7% of the cPAD for children 1-2 years old, the most highly exposed population subgroup.  Therefore, the chronic dietary risk is not of concern (i.e., <100% of the cPAD).  A summary of these results is shown in Table 5.4.5.

5.4.4	Cancer Dietary Risk Assessment

Chlorantraniliprole is classified as "not likely to be carcinogenic to humans"; therefore, a cancer assessment was not performed.

6.0 Residential (Non-Occupational) Exposure/Risk Characterization

6.1	Residential Handler Exposure

Although there are existing residential uses for chlorantraniliprole, residential exposure to chlorantraniliprole was not quantitatively assessed due to the lack of toxicity via inhalation and dermal routes. No risk is expected from residential handler exposure to chlorantraniliprole.



6.2	Post-Application Exposure

Due to the lack of toxicity via inhalation and dermal routes of exposure, as well as the lack of toxicity over the acute, short- and intermediate-term via the oral route, a residential post-application risk assessment is not required.

6.3	Residential Bystander Post-Application Inhalation Exposure

Based on the Agency's current practices, a quantitative post-application inhalation exposure assessment was not performed for chlorantraniliprole at this time primarily because of the low acute inhalation toxicity (Toxicity Category IV), low vapor pressure (6.3 x 10[-12] Pa @ 20˚C), and the low proposed use rate (0.099 lb ai/A).  However, volatilization of pesticides may be a source of post-application inhalation exposure to individuals nearby pesticide applications.  The Agency sought expert advice and input on issues related to volatilization of pesticides from its Federal Insecticide, Fungicide, and Rodenticide Act Scientific Advisory Panel (SAP) in December 2009, and received the SAP's final report on March 2, 2010.  The Agency is in the process of evaluating the SAP report and may, as appropriate, develop policies and procedures to identify the need for and, subsequently, the way to incorporate post-application inhalation exposure into the Agency's risk assessments.  If new policies or procedures are developed, the Agency may revisit the need for a quantitative post-application inhalation exposure assessment for chlorantraniliprole.

6.4	Spray Drift

Spray drift is a potential source of exposure to those nearby pesticide applications.  This is particularly the case with aerial application, but, to a lesser extent, spray drift can also be a potential source of exposure from the ground application methods (e.g., groundboom and airblast) employed for chlorantraniliprole.  The Agency has been working with the Spray Drift Task Force (a task force composed of various registrants which was developed as a result of a Data Call-In issued by EPA), EPA Regional Offices and State Lead Agencies for pesticide regulation and other parties to develop the best spray drift management practices (see the Agency's Spray Drift website for more information).  The Agency is also taking means to qualitatively and qualitatively address spray drift as a potential source of exposure in risk assessments for pesticides through existing programs such as Ag Drift and chemical specific properties of pesticides.  The potential for spray drift will be quantitatively evaluated for each pesticide during the Registration Review process which ensures that all uses for that pesticide will be considered concurrently.  

7.0 Aggregate Exposure/Risk Characterization

In accordance with the FQPA, HED must consider and aggregate (add) pesticide exposures and risks from three major sources: food, drinking water, and residential exposures.  In an aggregate assessment, exposures from relevant sources are added together and compared to quantitative estimates of hazard (e.g., a NOAEL or PAD), or the risks themselves can be aggregated.  When aggregating exposures and risks from various sources, HED considers both the route and duration of exposure.

An acute aggregate risk assessment was not performed because no appropriate endpoint was available to determine the aRfD for the general U.S. population or any population subgroup.  Short- and intermediate term aggregate risk was not performed because no hazard was identified over short- or intermediate-term durations.

Therefore, the aggregate risk assessment for chlorantraniliprole only includes chronic exposures to residues in food and drinking water.  The chronic dietary risk assessments for the U.S. population and all population subgroups are not of concern to HED (<100% cPAD).  The results of the chronic analysis indicate that the chronic dietary (food and water) risk estimates utilized 2.3% of the cPAD for the general U.S. population and utilized 6.7% of the cPAD for children 1-2 years old, the most highly exposed population subgroup.  

8.0 Cumulative Exposure/Risk Characterization

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 chlorantraniliprole and any other substances and chlorantraniliprole 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 chlorantraniliprole 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/.

9.0 Occupational Exposure/Risk Characterization

There is potential for short- and intermediate-term occupational exposure to chlorantraniliprole during both handler [mixing, loading, and application (via the dermal and inhalation routes)] and post-application activities (via the dermal route) based on the proposed uses.  However, the chlorantraniliprole toxicology database indicates there is no hazard associated with short- and intermediate-term dermal and inhalation exposure, and, therefore, no quantitative occupational exposure and risk assessment was conducted.
