the sufficiency of the submitted data at this time or whether the data 
support granting of the petition. Additional data may be needed before 
EPA rules on the petition.

A. Residue Chemistry

    1. Plant metabolism. The metabolism of benthiavalicarb-isopropyl 
was investigated in grapes, tomatoes, and potatoes. The rate of 
degradation in grapes and tomatoes is low and the unchanged parent is 
the major component, accounting for 90% or more of the total 
radioactive residue (TRR). The metabolites were below quantifiable 
levels in both grapes and tomatoes. Residues in foliar treated potato 
tubers showed more extensive metabolism with the unchanged parent 
accounting for only 4.7%, unidentified metabolites 76.5%, and 
unextracted radioactivity, 17.5%. About 21.9% of the unidentified 
metabolites are present as sugar conjugates. Analysis of the potato 
foliage from foliage treated plants indicated that 90% of the residue 
is unchanged parent and that no conversion to other isomers had 
occurred. Metabolites in the foliage were different than in the tubers 
and were identified as sugar conjugates of phenyl ring hydroxylated 
parent. The metabolism in potatoes occurs primarily via ring 
hydroxylation of the parent molecule. Secondary metabolism then occurs 
via. conjugation of sugar to the hydroxyl group. The residue of concern 
can be quantified as the unchanged parent.
    2. Analytical method. The proposed residue method involves analysis 
by gas chromatography with a nitrogen-phosphorous detector (GC/NPD). 
The limit of quantification (LOQ) for all matrices, raw agricultural 
and relevant processed fractions, was determined to be 0.01 ppm. The 
method is capable of measuring the unchanged parent as well a minor 
isomer present in the technical. However, the minor isomer is generally 
present at extremely low levels, often below the LOQ. Mean recoveries 
ranged from a low of 77% to a high of 112%, with standard deviations 
ranging from 2.0 to 18.7%.
    3. Magnitude of residues. The maximum average field trial residue 
measured in grapes was 0.22 ppm, although, the majority of the data at 
the proposed label rates was significantly below this level. The 
maximum residues observed in raisins and wine were 0.16 ppm and 0.08 
ppm, respectively.
     The maximum average residue observed in tomatoes was 0.22 ppm from 
trials conducted in the greenhouse. The residues observed in the field 
trials were significantly lower, with the residues in two of the three 
trials below the LOQ. The maximum residues observed in the processed 
commodities (all from greenhouse treated tomatoes) were as follows: 
Juice at 0.06 ppm, ketchup at 0.183 ppm, canned tomatoes at 0.035 ppm, 
and puree at 0.21 ppm.

B. Toxicological Profile

    1. Acute toxicity. The acute oral LD50 in Wistar rats is 
>5,000 milligrams/kilogram (mg/kg).
    2. Genotoxicity. Benthiavalicarb-isopropyl is negative in all tests 
conducted:
    i. Reverse mutation (S. typhimurium and e. coli).
    ii. In vitro chromosomal aberration (CHL cells),
    iii. In vitro mouse lymphoma (L5178Y cells),
    iv. In vitro unscheduled DNA synthesis (UDS) (rat hepatocytes),
    v. In vivo mouse miconucleus (mouse bone marrow),
    vi. In vivo gene mutation assay in transgenic mice (transgenic 
mouse liver), and
    vii. In vivo/in vitro UDS (rat hepatocytes).
    3.  Reproductive and developmental toxicity--i. In a 2-generation 
reproduction study in Sprague Dawley rats receiving 0, 100, 1,000 or 
10,000 ppm benthiavalicarb-isopropyl in the diet, the parental no 
observed adverse effect level (NOAEL) was 100 ppm based on hepatocyte 
hypertrophy at the next higher dose level. The reproductive NOAEL was 
10,000 ppm.
    ii. In a developmental toxicity study in New Zealand White rabbits 
receiving 0, 10, 20 or 40 mg/kg/day benthiavalicarb-isopropyl from day 
6 to 28 of gestation, the maternal NOAEL was 20 mg/kg/day based on 
abortion and increased liver weights at the 40 mg/kg/day dose. The 
developmental NOAEL was 20 mg/kg/day based on increased incidence of 
small fetus and delayed ossification of the hindlimb talus at 40 mg/kg/
day.
    iii. In a developmental toxicity study in Sprague Dawley rats 
receiving 0, 10, 100 or 1,000 mg/kg/day from day 7 to day 19 of 
gestation, the maternal NOAEL was 10 mg/kg/day based on elevated liver 
and adrenal weights at 100 mg/kg/day. The NOAEL for developmental 
toxicity was 1,000 mg/kg/day.
    4. Subchronic toxicity. i. In the 13-week feeding study with rats 
the dose levels were 0, 50, 200, 5,000, or 20,000 ppm in the diet. The 
NOAEL was 200 ppm, equivalent to 14.1 mg/kg/day and 15.3 mg/kg/day in 
males and females, respectively), based on blood chemistry and organ 
weight changes at 5,000 ppm.
    ii. In the 13-week feeding study with mice, the dose levels were 0, 
50, 200, 7,000, or 20,000 ppm. The NOAEL was 200 ppm (equivalent to 
33.0 mg/kg/day and 45.2 mg/kg/day in males and females, respectively, 
based on systemic toxicity of decreased body weights, anemias, and 
generalized liver toxicity at 7,000 ppm.
    iii. In the 3 month dog feeding study the dose levels were 0, 40, 
200, or 1,000 mg/kg/day. The NOAEL was 40 mg/kg/day based on 
hematological and clinical chemistry changes, organ weight changes and 
the findings of hepatocyte hypertrophy and pigmentation in the spleen 
at 200 mg/kg/day.
    5.  Chronic toxicity. i. In a chronic/oncogenicity study Fisher 
rats received 0, 50, 200, 5,000, or 10,000 ppm of benthiavalicarb-
isopropyl for up to 104 weeks. The NOAEL was 200 ppm (9.9 mg/kg/day and 
12.5 mg/kg/day in males and females respectively), based on a variety 
of toxic effects, primarily in the liver and kidney, and 
adenocarcinomas of the uterus at 5,000 ppm.
    ii. In an oncogenicity study in mice, the dietary doses were 0, 20, 
100, 2,500 or 5,000 ppm. The NOAEL was 100 ppm (13.7 mg/kg/day and 18.6 
mg/kg/day in males and females, respectively) based on a variety of 
toxic effects, primarily in the liver and kidney, and hepatocellular 
blastoma and carcinoma at 2,500 ppm.
    iii. In a 52-week study with Beagle dogs, the dietary dose levels 
were 0, 4, 40, or 400 mg/kg/day. The NOAEL was 40 mg/kg/day based on 
increased liver weights in males and females at 400 mg/kg/day.
    iv. Numerous supplemental mechanistic studies in the rodent were 
carried out to further elucidate the mechanisms involved in tumor 
formation in the lifetime rodent studies. These studies indicated that

[[Page 11651]]

benthiavalicarb-isopropyl behaves like a promotor following initiation 
with diethylnitrosamine (DEN), and does not have initiating activity. 
The compound did not cause oxidative damage in studies on rat or mouse 
liver, was a slight enzyme inducer, and did not cause hepatocyte 
proliferation.
    6. Animal metabolism. Benthiavalicarb-isopropyl is rapidly absorbed 
at the dose levels tested in both sexes. The distribution of 
radioactivity was generally throughout the body, with the liver having 
the highest levels at all time points. Excretion was predominantly via 
the bile. The metabolism was complex. The predominant routes of 
metabolism were gluthione conjugation or hydroxylation on the benzene 
or valyl moieties. This resulted in a large number of metabolites, many 
present only in small quantities.
    7. Metabolite toxicology. It was concluded that no specific 
metabolite toxicity studies were needed.
    8. Endocrine disruption. Benthiavalicarb-isopropyl was tested for 
its potential to induce hormomimetic effects in ovariectimized rats, 
potential effects on estradiol, progesterone, LH and aromatase activity 
in the rat, and potential effects on thyroid hormones in the rat and 
mouse. Under the conditions of these studies, no endocrine disrupting 
activity was displayed.

C. Aggregate Exposure

    1. Dietary exposure. There are no registered uses of 
benthiavalicarb-isopropyl in the United States, (U.S.) and no other 
tolerance petitions have been submitted to EPA for this active 
ingredient. Dietary exposure is limited in the U.S. to residues in/on 
imported grapes and tomatoes and their processed components. A Tier I 
exposure analysis was conducted which assumed that 100% of the imported 
grape and tomato products consumed in the U.S. contained residues at 
the proposed tolerance levels. This is a ``worst case'' scenario in two 
ways-the product is not and will not be registered for use in many of 
the countries exporting these commodities to the U.S., and it is 
unlikely that all residues will be at the tolerance levels. Based on 
the expected reference dose (RfD) of 0.1 mg/kg/day, the exposure to the 
general population in this worst case scenario is 0.17% of the RfD. 
Based on an aRfD of 0.1 mg/kg/day, the exposure to the general 
population in this worst case scenario is 1.18 % of the aRfD. Cancer 
dietary exposure estimates were also conducted, which indicate that 
with a very conservative Q* and linear extrapolation, the cancer risk 
is acceptable.
    i. Food. This is a new chemical and there are no other food uses 
except for the proposed uses on grapes and tomatoes.
    ii. Drinking water. No exposure is expected from drinking water as 
this is an import tolerance and no U.S. registrations are expected.
    2. Non-dietary exposure. There are no non-occupational sources of 
exposure to benthiavalicarb-isopropyl for the general population due to 
the fact that the requested action is to establish tolerances for 
import purposes only.

D. Cumulative Effects

     There is no evidence available to suggest that benthiavalicarb-
isopropyl has a mode of action that is common with other registered 
pesticides. Therefore K-I Chemical U.S.A. Inc. has considered only the 
potential risks of benthiavalicarb-isopropyl in the exposure 
assessments.

E. Safety Determination

    1. U.S. population. Using the exposure assumptions described above, 
based on the completeness and the reliability of the toxicity data, K-I 
Chemical U.S.A. has estimated that aggregate exposure to 
benthiavalicarb-isopropyl will utilize less than 1% of the RfD for the 
U.S. population. EPA generally has no concern for exposure below 100% 
of the RfD. Therefore, based on the completeness and the reliability of 
the toxicity data, and the exposure assessment discussed above, K-I 
Chemical U.S.A. concludes that there is a reasonable certainty that no 
harm will result from aggregate exposure to residues of 
benthiavalicarb-isopropyl, including all anticipated dietary and all 
other non-occupational exposures.
    2. Infants and children. Benthiavalicarb-isopropyl did not display 
reproductive toxicity in rats and the data show that pups are not more 
sensitive to the effects of the compound than adults are. The compound 
was not a developmental toxicant in the tests conducted, with only 
delayed growth due to maternal toxicity observed. The rat and rabbit 
developmental studies indicate that the fetuses were not more sensitive 
than the adults to the effects of the test compound. Therefore, no 
additional safety factor is needed for children.
     Using the same worst case assumptions as for the general 
population, K-I Chemical concludes that the most sensitive population 
group for chronic assessment is children 1-6. The exposure to this 
group is 0.56% of the chronic RfD. For acute exposure assessment, the 
most sensitive population is non-nursing infants, with an exposure 
estimate utilizing about 5% of the acute reference dose. Therefore, 
based on the toxicity data and the worst case estimates of exposure, K-
I Chemical U.S.A. concludes that there is a reasonable certainty that 
no harm will result to infants and to children from aggregate exposure 
to residues of benthiavalicarb-isopropyl, including all anticipated 
dietary exposure and all other non-occupational exposures.

F. International Tolerances

     Currently there are no international tolerances.
