Arvesta Corporation

PP 4F6869

    EPA has received a pesticide petition (4F6869) from Arvesta 
Corporation, 100 First Street, Suite 1700, San Francisco, CA 94105 
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 a tolerance for residues of clothianidin in or on the raw 
agricultural commodities grapes at 0.5 parts per million (ppm), raisins 
at 1.0 ppm, and potatoes at 0.1 ppm. EPA has determined that the 
petition contains 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 petition. Additional data may be needed before 
EPA rules on the petition.

A. Residue Chemistry

    1. Plant metabolism. In plants, the metabolism of clothianidin is 
adequately understood for the purposes of establishing these proposed 
tolerances. Unchanged, parent clothianidin was the predominant residue 
in all crop matrices (14.4 to 64.5% in corn, 66.1 to 96.6% in tomatoes, 
4.3 to 24.4% in sugar beets and 24.3 to 63.3% in apples), with the 
exception of sugar beet leaves. In sugar beet leaves, the main 
components were the methylguanidine and thiazolylmethylguanidine (TMG) 
metabolites, accounting for 28.6 and 27.7% respectively. All 
metabolites found in plants were also found in the animal metabolism 
studies. In animals, parent clothianidin was the major component in 
liver, muscle and fat. Based on the available metabolism data, parent 
clothianidin, TZG, TZU, and ATMG-Pyr are proposed to be considered as 
the residues of concern in livestock matrices.
    2. Analytical method. In plants and plant products, the residue of 
concern, parent clothianidin, can be determined using high performance 
liquid chromatography (HPLC) with electrospray mass spectroscopy (MS/
MS) detection. In an extraction efficiency testing, the plant residues 
method has also demonstrated the ability to extract aged clothianidin 
residue.
    In animal matrices, the residues parent clothianidin, TZG, TZU, and 
ATMG-Pyr can also be determined using HPLC with electrospray MS/MS 
detection. In an extraction efficiency testing, the animal residues 
method can also extract aged clothianidin, TZG, TZU, and ATMG-Pyr 
residues.
    Although for the plant and animal residues this HPLC-MS/MS method 
is highly suitable as an enforcement method, an LC-ultraviolet (UV) 
method has also been developed which is suitable for enforcement 
(monitoring) purposes in all relevant matrices.
    3. Magnitude of residues-- i. Potatoes. Fifteen residue trials were 
conducted in key potato producing regions of the United States. At each 
trial, two different application regimes, foliar and in-furrow, were 
studied in separate plots. Samples were analyzed for residues of 
clothianidin.
    Three foliar applications of 0.0661 pounds (lb) per active 
ingredient/acre (ai/A) were made with the 50 WDG formulation at 28, 21 
and 14 days prior to harvest. Clothianidin residues ranged from ND to 
0.0205 ppm for this treatment.
    One in-furrow application of 0.198 lb ai/A was made with the 16 WSG 
formulation. Clothianidin residues ranged from less than the limit of 
detection (LOD) (0.007 ppm) to 0.0332 ppm for this treatment.
    At one of the trial sites, two additional plots were treated at 5X 
the normal application rate for the processing phase of the study. 
Spray volumes range from 13.3 to 31.2 gallons per acre (GPA). The 
processing portions analyzed were whole tubers, granules, chips, and 
wet peel.
    The foliar application of 50WDG was made at the 5X rate of 0.331 lb 
ai/A for the processing phase of the study. All of the clothianidin 
mean residues were less than limit of quantitation (LOQ) except for 
granules, which had mean clothianidin residues of 0.0316 ppm. The 
concentration factor (CF) for granules was calculated as 3.2. It was 
not possible to calculate a reliable CF in commodities other than 
granules. A residue decline study indicated that residues do not 
increase with longer preharvest intervals (PHI).
    The in-furrow application of 16WSG was made at the 5X rate of 0.99 
lb ai/A for the processing phase of the study. Clothianidin mean 
residues in whole tubers, granules, chips, and wet peel were 0.0258, 
0.0546, 0.04 (< LOQ), and 0.007 (50 was 
>5,000 milligram/kilogram (mg/kg) for both male and

[[Page 71039]]

female rats and the acute dermal LD50 was >2,000 mg/kg in 
rats. The four-hour inhalation LC 50 was 6.14 mg/L for male 
and female rats. Clothianidin was not a dermal or eye irritant in 
rabbits and was not a skin sensitizer in guinea pigs.
    2. Genotoxicty. Extensive mutagenicity studies were conducted with 
clothianidin. Based on the weight of evidence, clothianidin was 
considered negative for genotoxicity.
    3. Reproductive and developmental toxicity. In a 2-generation 
reproduction study with clothianidin, rats were administered dietary 
levels of 0, 150, 500 and 2,500 ppm. The no observed effect level 
(NOEL) for reproductive parameters was 2,500 ppm. The NOEL for 
developmental effects was 500 ppm based on decreased pup weights and 
the parental NOEL was 150 ppm based on decreased body weights (bw).
    A developmental toxicity study was conducted in rats with 
clothianidin using dose levels of 0, 10, 50 and 125 mg/kg/day by 
gavage. The NOEL for maternal toxicity was established at 10 mg/kg and 
for developmental effects it was >125 mg/kg. Additionally, a 
developmental toxicity study was conducted with rabbits treated orally 
by gavage at 0, 10, 25, 75 and 100 mg/kg/day. The NOEL for maternal 
toxicity was 10 mg/kg and for developmental toxicity, it was 75 mg/kg.
    Developmental toxicity studies showed no primary developmental 
toxicity and no teratogenic potential was evident.
    4. Subchronic toxicity.90-day feeding studies were conducted in 
rats and dogs. The rat study was conducted at dietary levels of 0, 150, 
500 and 3,000 ppm and the dog study was conducted at 0, 325, 650 and 
1,500 ppm. The NOELs were established at 500 ppm for rat and 650 ppm 
for the dog.
    5. Chronic toxicity. A 2-year combined rat chronic/oncogenicity 
study conducted at dietary levels of 0, 150, 500, 1,500 and 3,000 ppm 
demonstrated a NOEL of 150 ppm based on reduced weight gains and non-
neoplastic histomorphological changes. A 78-week mouse oncogenicity 
study conducted at dose levels of 0, 100, 350, 1,250, and 2,000/1,800 
ppm for males and females, respectively, revealed a NOEL of 350 ppm 
based on reduced bw gains and increased incidence of hypercellular 
hypertrophy. No evidence of oncogenicity was seen in the rats or the 
mice. A 52-week chronic toxicity study in dogs conducted at dietary 
levels of 0, 325, 650, 1,500 and 2,000 ppm revealed an overall NOEL of 
325 ppm and no observed adverse effect level (NOAEL) of 650 ppm based 
on a slight decrease in ALT.
    6. Animal metabolism. The nature of the clothianidin residue in 
livestock is adequately understood. In animals, parent clothianidin was 
the major component in liver, muscle and fat. Based on the available 
metabolism data, parent clothianidin, TZG, TZU, and ATMG-Pyr are 
proposed to be considered as the residues of concern in livestock 
matrices.
    7. Metabolite toxicology. Eight in vivo metabolites of clothianidin 
identified in the rat were investigated for acute oral endpoint 
mutagenic activity. None of the metabolites were mutagenic either with 
or without activation and the LD50 values range from <500 to 
>2,000 mg/kg, showing low to moderate toxicity.
    8. Endocrine disruption. All guideline studies conducted to 
characterize the toxicological profile showed no endocrine related 
toxicity or tumorgenicity. No effects on T3, T4, or TSH were observed 
in the subchronic rat study. In a 2-generation reproduction study in 
the rat, and rat and rabbit teratology studies, clothianidin did not 
show reproductive or teratogenic effects. The extensive database shows 
that clothianidin has no endocrine properties.

C. Aggregate Exposure

    1. Dietary exposure. Tolerances are proposed for residues of 
clothianidin on grapes, raisins, and potatoes. For the purposes of 
assessing the potential dietary exposure for these proposed tolerances, 
an exposure assessment was conducted using Dietary Exposure Evaluation 
Model (DEEM\TM\) software, consumption data derived from the 1994-1998 
USDA Continuing Surveys of Food Intake by Individuals (CSFII), and 
residue levels at proposed tolerance levels.
    i. Food -- a. Acute dietary exposure. The acute population adjusted 
dose (aPAD) of 0.25 mg/kg bw/day (acute NOAEL with a 100-fold 
uncertainty factor) was used to assess dietary exposure. Arvesta 
Corporation has conducted an acute dietary exposure Tier 1 analysis 
with DEEM\TM\ using the proposed tolerances for grapes, raisins, and 
potatoes of 0.5, 1.0, and 0.1 ppm, respectively, 100% crop treated and 
default processing factors for the overall US population and the 
following subpopulations: All infants (<1 year), children (1-2 years), 
females (13-49 years), and adults (50+). Arvesta has conducted an acute 
Tier 1 analysis from the uses on grapes and potatoes. This analysis 
also includes the anticipated exposure to clothianidin resulting from 
both Bayer's seed treatment uses and uses of thiamethoxam, of which 
clothianidin is a major metabolite. The results of this Tier 1 analysis 
indicate that the highest exposure never exceeds 18.00% of the aPAD at 
the 95th percentile of exposure.
    b. Chronic dietary exposure. The chronic population adjusted dose 
(cPAD) of 0.098 mg/kg bw/day (chronic NOEL with a 100-fold uncertainty 
factor) was used to assess chronic dietary exposure. Arvesta has 
conducted a chronic Tier 1 analysis, including the anticipated exposure 
to clothianidin resulting from Bayer's seed treatment uses and uses of 
thiamethoxam, and the results indicate that the highest exposure never 
exceeds 13.41% of the cPAD.
    ii. Drinking water. For drinking water, the models screening 
concentration in ground water (SCI-GROW) (ground water) and the Food 
Quality Protection Act (FQPA) index reservoir screening tool (FIRST) 
(surface water), were selected to calculate the potential exposure of 
clothianidin in drinking water. Both short-term (acute) and long-term 
(chronic) exposures were estimated with respect to foliar and drip-
irrigation uses for grapes and foliar and in-furrow uses for potatoes. 
The worst case drinking water estimated concentrations (DWEC) for these 
applications to grapes and potatoes were 15.1 parts per billion (ppb) 
for the acute and 0.5 ppb for the chronic using the FIRST model. The 
acute and chronic drinking water levels of comparison (DWLOC) were 
calculated for each of the population subgroups. The acute DWLOC for 
the most sensitive population subgroup, children 1-2 years, was 
calculated to be 2,050 ppb and the chronic DWLOC for this population 
subgroup is 849 ppb. The acute DWLOC for the U.S. population is 8,417 
ppb and the chronic DWLOC is 3,350 ppb. The calculated acute and 
chronic DWLOCs for the U.S. population and children 1-2 years exceed 
the DWECs from the models.
    2. Non-dietary exposure. Clothianidin is currently not registered 
for use on any residential non-food site. Therefore, residential 
exposure to clothianidin residues will be through dietary exposure 
only.

D. Cumulative Effects

    There is no information available to indicate that toxic effects 
produced by clothianidin are cumulative with those of any other 
compound.

E. Safety Determination

    1. U.S. population. Using the conservative exposure assumptions 
described above and based on the completeness of the toxicity data, it 
can be concluded that total food-only exposure to clothianidin from all

[[Page 71040]]

proposed crop uses will be less than 3.8% of the aPAD and less than 
2.34% of the cPAD for the overall U.S. population. All evaluated 
population subgroups had an exposure of less than 18.00% of the aPAD 
and less than 13.41% of the cPAD. EPA generally has no concerns for 
exposures below 100% of the PAD, because the PAD represents the level 
at or below which daily aggregate exposure over a lifetime will not 
pose appreciable risks to human health. The DWLOCs exceed the DWECs as 
calculated by conservative models. There are no residential uses of 
clothianidin; therefore, aggregate exposure consists of food and 
drinking water exposures. Thus, it can be concluded that there is a 
reasonable certainty that no harm will result from aggregate exposure 
to clothianidin residues.
    2. Infants and children. In assessing the potential for additional 
sensitivity of infants and children to residues of clothianidin, the 
data from developmental toxicity studies in both the rat and rabbit, a 
2-generation reproduction study in rats and a developmental 
neurotoxicity study in rats have been considered.
    The developmental toxicity studies evaluate potential adverse 
effects on the developing animal resulting from pesticide exposure of 
the mother during prenatal development. The reproduction study 
evaluates effects from exposure to the pesticide on the reproductive 
capability of mating animals through two generations, as well as any 
observed systemic toxicity.
    The developmental neurotoxicity studies evaluate the 
neurobehavioral and neurotoxic effects on the developing animal 
resulting from the exposure of the mother. FFDCA section 408 provides 
that EPA may apply an additional uncertainty factor for infants and 
children based on the threshold effects to account for prenatal and 
postnatal effects and the completeness of the toxicity database. Based 
on the current toxicological data requirements, the toxicology database 
for clothianidin relative to prenatal and postnatal development is 
complete, including the developmental neurotoxicity study. None of the 
studies indicated the offspring to be more sensitive. All effects were 
secondary to severe maternal toxicity. The cPAD for clothianidin was 
calculated using the NOAEL of 9.8 mg/kg bw/day from the 2-generation 
rat reproduction study.

F. International Tolerances

    No CODEX maximum residue levels (MRL's) have been established for 
residues of clothianidin on any crops at this time.
