Syngenta Crop Protection
PP 7E4916, 8E5029, 8E5030, 9E6055, and 2E6374
EPA has received pesticide petitions (7E4916, 8E5029, 8E5030, 9E6055, and 2E6374) from the Interregional Research Project Number 4 (IR-4), 681 U.S. Highway #1 South, North Brunswick, NJ 08902 proposing proposing, pursuant to section 408(d) of the Federal Food, Drug, and Cosmetic Act (FFDCA), 21 U.S.C. 346a(d), to amend 40 CFR part 180 by establishing tolerances for combined residues of s-metolachlor and its metabolites, determined as the derivatives, 2-(2-ethyl-6-methylphenyl)amino-1-propanol and 4-(2-ethyl-6-methylphenyl)-2-hydroxy-5-methyl-3-morpholine, each expressed as the parent compound s-metolachlor in or on the following raw agricultural commodities:
1. PP 4E4420 proposes the establishment of tolerances for pepper, bell and pepper, nonbell at 0.50 part per million (ppm).
2. PP 7E4916 proposes the establishment of a tolerance for carrot, root and horseradish at 0.1 ppm.
3. PP 8E5029 proposes the establishment of a tolerance for rhubarb at 0.1 ppm.

5. PP 9E6055 proposes the establishment of a tolerance for asparagus at 0.1 ppm.
6. PP 2E6374 proposes the establishment of a tolerance for onion, green at 0.2 ppm.
EPA has determined that the petitions contain data or information regarding the elements set forth in section 408(d)(2) of the FFDCA; however, EPA has not fully evaluated the sufficiency of the submitted data at this time or whether the data supports granting of the petitions. Additional data may be needed before EPA rules on the petitions.
A. Residue Chemistry
1. Plant metabolism. [The qualitative nature of S-metolachlor residues in plants is adequately understood based upon available EPA approved corn, potato, and soybean metabolism studies. The metabolism of S-metolachlor involves conjugation with glutathione, breakage of this bond to form the mercaptan, conjugation of the mercaptan with glucuronic acid, hydrolysis of the methyl ether, and conjugation of the resultant alcohol with a neutral sugar. EPA has determined that residues of concern in plants include parent and metabolites, determined as the derivatives CGA-37913 and CGA-49751.
2. Analytical method. The Pesticide Analytical Manual (PAM) Vol. II, Pesticide Regulation Section 180.368 lists a gas chromatography/nitrogen phosphorous detector (GC/NPD) method (Method 1) for determining residues in or on plants and a gas chromatography/mass spectrometry methos (GC/MSD) method for determining residues in livestock commodities. These methods determine residues of S-metolachlor and its metabolites as either CGA-37913 or CGA-49751 following acid hydrolysis. The limit of quantitation (LOQ) for the method is 0.03 ppm for CGA-37913 and 0.05 ppm for CGA-49751.
3. Magnitude of residues.—i. Asparagus. Magnitude of residue trials were conducted under the direction of IR-4 in EPA regions 2, 5, and 11 in New Jersey, Michigan, and Washington. Applications were made pre-emergence to dormant asparagus in the spring and samples were collected for analysis 16 days after application. There were no detectable residues found in asparagus at harvest.
ii. Carrot. Field trials were conducted in Florida, Michigan, and New York to support the proposed tolerance for S-metolachlor in or on carrots grow on high organic matter (muck) soils.
iii. Green onion. Magnitude of residue trials were completed by IR-4 in New York, California, and Michigan (EPA region 1, 10, and 5, respectively). One post-emergence broadcast application was made when the onions had 2 true leaves. Marketable green onion plants were collected 43 to 45 days following the application. Maximum residues found were 0.168 ppm.
iv. Rhubarb and Swiss chard. As the EPA review announced in the October 2002 TRED has confirmed that a 0.1 ppm tolerance is appropriate for S-metolachlor in celery and as celery is the representative crop for the Leafy Petiole Subgroup, IR-4 has proposed tolerances be established for rhubarb and Swiss chard.
B. Toxicological Profile
1. Acute toxicity. [The data base for acute toxicity for S-metolachlor is complete. S-metolachlor is moderately acutely toxic (Toxicity Category III) by the oral and dermal route and relatively non-toxic (Toxicity category IV) by the inhalation route. It causes slight eye irritation (Toxicity Category III) and is non-irritating dermally (Toxicity Category IV); the active ingredient was found to be positive in a dermal sensitization test but this effect is mitigated in end-use product formulations.]
2. Genotoxicty. The data base for S-metolachlor has been deemed to be adequate by EPA. Gene mutation studies (Guideline 870.5100), micronucleus (Guideline 870.5395), and unscheduled DNA synthesis (Guideline 870.5550) studies have recently been reviewed and approved by EPA. There is no evidence of a mutagenic or cytogentic effect in vivo or in vitro with S-metolachlor.
3. Reproductive and developmental toxicity. The data base for developmental and reproductive toxicity for S-metolachlor are considered complete according to EPA reviews. The prenatal developmental studies in the rat and rabbit with S-metolachlor revealed no evidence of a qualitative or quantitative susceptibility in fetal animals. No significant developmental toxicity was observed in most studies even at the highest doses tested. In a two-generation reproduction study, there was no evidence of parental or reproductive toxicity at the highest dose tested (80 mg/kg/day). The results indicate that S-metolachlor is not Start Printed Page 48376embryotoxic or teratogenic in either species at maternally toxic doses.
4. Subchronic toxicity. In a 90-day dietary study in rats with S-metolachlor, no effects were observed in male or females at 208 and 236 mg/kg/day, respectively. In another 90-day dietary study in rats, decreased body weight, reduced food consumption and food efficiency in both sexes and increased kidney weight in males at 150 mg/kg/day; the NOAEL was 15 mg/kg/day. A 90-day dog study with S-metolachlor in dogs has been accepted by EPA; no effects were observed in males and females at 62 mg/kg/day and 74 mg/kg/day, respectively, the highest doses tested.
5. Chronic toxicity. A combined chronic toxicity/carcinogenic study in the rat satisfies the requirements for both the chronic toxicity and carcinogenicity studies. No significant chronic toxicity was found in either rats or dogs. In the rat, a decrease in body weight was observed at the highest dose tested. In the chronic dog study that supports S-metolachlor, the only adverse effect was decreased body weight gain in females at 33 mg/kg/day; the NOAEL was 10 mg/kg/day.
6. Animal metabolism. In animals, S-metolachlor is extensively absorbed, rapidly metabolized and almost totally eliminated in the excreta of rats, goats, and poultry. Metabolism in animals proceeds through common Phase 1 intermediates and glutathione conjugation.
7. Metabolite toxicology. The metabolism of S-metolachlor has been well characterized in standard FIFRA metabolism studies. S-metolachlor does not readily undergo dealkylation to form an aniline or quinone imine as has been reported for other members of the chloroacetanilide class of chemicals. Therefore, it is not appropriate to include S-metolachlor with the group of chloroacetanilides that readily undergo dealkylation, producing a common toxic metabolite (quinone imine). New toxicology data submitted by Syngenta demonstrate that the S-metolachlor metabolites ethane sulfonic acid (CGA 354743) and oxanilic acid (CGA 51202) are not absorbed by mammalian systems and / or have a significantly lower level of mammalian toxicity when compared to parent.
8. Endocrine disruption. S-Metolachlor does not belong to a class of chemicals known or suspected of having adverse effects on the endocrine system. There is no evidence that S-metolachlor has any effect on endocrine function in developmental or reproduction studies. Furthermore, histological investigation of endocrine organs in the chronic dog, rat and mouse studies did not indicate that the endocrine system is targeted by S-metolachlor, even at maximally tolerated doses administered for a lifetime. There is no evidence that S-metolachlor bioaccumulates in the environment.
C. Aggregate Exposure
1. Dietary exposure. A Tier III/IV chronic dietary exposure analysis was conducted on S-metolachlor using field trial and market basket survey residues. Field trial residues were adjusted for percent of crop treated whereas market basket residues were not, since this information is inherent in the data. The percent of crop treated was assumed to be 100% for all commodities for which no percent of crop treated information was available. The chronic assessment was conducted for S-metolachlor using the Dietary Exposure Evaluation Model (DEEMTM, version 7.76) by Exponent and food consumption information from USDA's 1994-96 Continuing Survey of Food Intake by Individuals (CSFII) and the Supplemental CSFII children's survey (1998). For this chronic assessment, the field trial values were averaged and entered into the DEEMTM software.
Syngenta Market Basket Survey (SMBS) S-metolachlor data were available for the following commodities: milk, potatoes and tomatoes. The Syngenta market basket survey was conducted from September 1999 through September 2000. Following the Agency tier ranking system, these chronic dietary assessments are considered as Tier III (utilizing field trial data) and Tier IV (utilizing SMBS and PDP data) assessments.
S-metolachlor is not considered acutely toxic and therefore acute dietary exposure was not determined; however, in the October 2002 TRED EPA conducted an acute assessment of the majority of the crops included in this petition and determined acute risks to be <1% of the aPAD in the most exposed population subgroup.
The chronic RfD for S-metolachlor is 0.10 mg/kg body weight/day and is based on a one-year dog study with a NOEL of 9.7 mg/kg body weight/day and a safety factor of 100X. No additional FQPA safety factor is required; nor was applied in this assessment.
i. Food. The risk from chronic dietary exposure to S-metolachlor is considered to be very low. The percentages of the chronic RfD ranged from 0.17% for Seniors to 0.64% for Children 1-2 years old, theoretically the most exposure population subgroup.
ii. Drinking water. Other potential sources of exposure of the general population to residues of S-metolachlor are residues in drinking water and exposure from non-occupational sources. The degradation of S-metolachlor is microbially mediated with an aerobic soil metabolism primary half-life of less than 30 days and subsequently soil binding predominates. S-metolachlor Koc's vary from 110- 369. S-metolachlor is stable to hydrolysis and while aqueous and soil photolysis occur, they are not expected to be prominent pathways in the environment.
The predominant crop for S-metolachlor is corn and accordingly an Index Reservoir PRZM/EXAMS was run using EPA's standard corn scenario. The model simulated two applications to the same plot: pre-emergence (2.67 kg ai/ha) and post-emergence (1.50 kg a.i./ha). The mean annual average estimated environmental concentrations (EEC) was 11.77 ppb. It should be noted that extensive monitoring data suggests that this EEC is a conservative estimate. For the vast majority of locations sampled, the peak measured concentration does not approach 12 ppb, and the annual average would be expected to be much lower.
The Chronic drinking water levels of concern (DWLOC) was calculated based on a cRfD of 0.097 mg/kg/day. Non-nursing infants are the most sensitive subpopulation and their DWLOC is estimated to be 544 ppb which corresponds to a %cRfD value of 2.2% with an MOE value of 4621. Thus, the DWLOC is considerably higher than the EEC of 11.77 ppb and the MOE is well above the benchmark value of 100.
2. Non-dietary exposure. S-metolachlor is labeled for use on warm-season turf and landscape ornamentals. Although, it is primarily used on sod farms and commercial landscape ornamentals, it can be used by licensed pest control operators (PCO) or lawn care operators (LCO) on residential turf. Since S-metolachlor can only be applied to warm-season turf varieties (bermudagrass, Zoysiagrass, St. Augustinegrass, and Centipedegrass), its use on turf is limited to the southern states.
Non-dietary residential exposure may occur to homeowners or children as a result of exposure during re-entry activities. Using surrogate dislodgeable foliar residue data, and conservative standard EPA exposure scenarios, exposure through the dermal route was calculated. Based on the use pattern, which restricts to number of application to one per year, only short-term risks need to be considered. The relevant Start Printed Page 48377toxicological endpoint for short-term dermal risks is the NOEL of 100 mg/kg/day from a 21-day dermal toxicity study in rabbits. No acute oral hazard has been identified following an acute exposure to S-metolachlor and, therefore, no nondietary assessment is needed.
The short-term dermal post-application risks for adults and children are acceptable, ranging from 520 to 870. These risk estimates exceed the EPA's level of concern for S-metolachlor (all MOEs are greater than 100).
Aggregate exposure. (Drinking Water and Dietary Exposure). Using the total MOE equation for the determination of aggregate chronic exposure (food and drinking water only) resulted in an aggregate MOET of >4,000 for the most sensitive subpopulation, non-nursing infants. For this particular subpopulation, there are no non-dietary exposure contributions to the MOET aggregate value.
D. Cumulative Effects
EPA has examined the common mechanism potential for S-metolachlor and has concluded that S-metolachlor should not be included with some pesticides that comprise the class of chloroacetanilides included in a “Common Mechanism Group.” Therefore, a cumulative assessment is not necessary for S-metolachlor.
E. Safety Determination
1. U.S. population. Based on the aggregate assessment described above and the completeness and reliability of the toxicity data, it is concluded that aggregate exposure to S-metolachlor (including the proposed uses) in food will utilize less than 0.1 percent of the cRfD for the U.S. population. EPA generally has no concern for exposures below 100 percent of the RfD because the RfD represents the level at or below which daily aggregate dietary exposure over a lifetime will not pose appreciable risks to human health. Despite the potential for exposure to S-metolachlor in drinking water and from non-dietary, non-occupational exposures, the assessment presented above demonstrates that the high levels of safety exist for current and proposed uses of S-metolachlor; it is not expected that aggregate exposure from all sources will exceed 100% of the RfD. Therefore, one can conclude there is a reasonable certainty that no harm will result from aggregate exposure to S-metolachlor.
2. Infants and children. [FFDCA section 408 provides that EPA may apply an additional safety factor for infants and children in the case of threshold effects to account for pre- and post-natal toxicity and the completeness of the database. Based on the current toxicological data requirements, the database relative to pre- and post-natal effects for children is complete. A full consideration of the available reproductive toxicity data supporting S-metolachlor demonstrates no increased sensitivity to infants and children. Therefore, it is concluded that an additional uncertainty factor is not warranted to protect the health of infants and children and that the cRfD at 0.1 mg/kg/day is appropriate for assessing aggregate risk to infants and children from use of S-metolachlor.
Based on the aggregate assessment described above, the percent of the cRfD that will be utilized by aggregate exposure to residues of S-metolachlor is less than 0.7 percent for all children subpopulations. EPA generally has no concern for exposures below 100% of the RfD because the RfD represents the level at or below which daily aggregate dietary exposure over a lifetime will not pose appreciable risks to human health. Despite the potential for exposure to S-metolachlor in drinking water and from non-dietary, non-occupational exposure, the assessment described above demonstrates that it is not expected that aggregate exposure from all sources provides for a large margin of safety and will exceed 100% of the RfD. Therefore, based on the completeness and reliability of the toxicity data and the exposure assessment, it is concluded there is a reasonable certainty that no harm will result to infants and children from aggregate exposure to S-metolachlor residues.
F. International Tolerances
There are no Codex Alimentarius Commission (CODEX) maximum residue levels (MRL's) established for residues of S-metolachlor in or on raw agricultural commodities.End Supplemental Information
