SUPPLEMENTARY INFORMATION: EPA has received pesticide petitions (PP 5F4572 and
PP 5F4440) from Valent U.S.A. Corporation, 1333 N. California Blvd., Walnut
Creek, CA 94596 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 residues of the herbicide clethodim in or on the
following raw or processed agricultural commodities: tomatoes at 1.0 part per
million (ppm); tomato puree at 2.0 ppm; tomato paste at 3.0 ppm; alfalfa
forage at 6.0 ppm; alfalfa hay at 10.0 ppm; peanut nutmeat at 3.0 ppm; peanut
hay at 3.0 ppm; peanut meal at 5.0 ppm; and dry bean seeds at 2.0 ppm. The
proposed enforcement analytical method for these commodities is EPA-RM-26D-3,
a high-performance liquid chromatography (HPLC) method. EPA has determined
that the petition contains data or information regarding the elements set

summary for the purpose of clarity.
I. Petition Summary
A. Residue Chemistry
1. Plant metabolism. Clethodim is used for postemergent control of grasses in
a wide variety of crops including cotton, soybeans, sugar beets, onions, etc.
Plant metabolism studies have been performed in carrots, soybeans, and cotton.
Studies were performed with clethodim radio-labeled in the ring structure and
in the side chain to follow both parts of the molecule.
The major metabolic pathway in plants is initial sulfoxidation to form
clethodim sulfoxide followed by further sulfoxidation to form clethodim
sulfone; elimination of the chloroallyloxy side chain to give the imine
sulfoxide and sulfone; and hydroxylation to form the 5-OH sulfoxide and 5-OH
sulfone. Clethodim sulfoxide and clethodim sulfone conjugates were also
detected as major or minor metabolites, depending on plant species and
subfractions. Once cleaved from clethodim, the chloroallyloxy moiety undergoes
extensive metabolism to eliminate the chlorine atom and incorporate the three-
carbon moieties into natural plant components. EPA has determined that the
nature of the residue is adequately understood for the purposes of this
petition (memos from J. Morales, February 8, 1996 and June 25, 1996).
Based on these metabolism studies, the residues of concern in crops are
clethodim and its metabolites containing the cyclohexene moiety, and their
sulfoxides and sulfones.
2. Analytical methods. Adequate analytical methodology is available for
detecting and measuring levels of clethodim and its metabolites in crops. For
most commodities, the primary enforcement method is EPA-RM- 26D-3, an HPLC
method capable of distinguishing clethodim from the structurally related
herbicide sethoxydim. However, for milk natural interferences prevent adequate
quantitation of clethodim moieties and the common-moiety method (RM-26B-2) is
the primary enforcement method with EPA-RM-26D-3 as the secondary method if
needed to determine whether residues are clethodim or sethoxydim. Both of
these methods have successfully undergone petition method validations at EPA.
3. Magnitude of residues. Clethodim is the active ingredient in SELECT 2 EC
Herbicide (EPA Reg. No. 59639-3) and SELECT Herbicide (also known as PRISM and
ENVOY Herbicides, EPA Reg. No. 59639-78). Tolerances have been established for
residues in cotton, soybean, sugar beet, onion (dry bulb), and animal
commodities. A summary of available field residue data for the pending
tolerances on tomato, alfalfa, peanut, and dry bean commodities is presented
In 12 field trials, tomatoes were treated with two post-emergent applications
of 0.25 lb. a.i./A each, approximately 14 days apart, and harvested
approximately 20 days after the last application. Both fresh and processing
tomatoes were included and trials were performed in EPA growing regions 1, 2,
3, 5, and 10. Residues for individual tomato fruit samples ranged from < 0.1
ppm to 0.82 ppm. The highest average field trial (HAFT) residue was 0.77 ppm.
The average residue value for all trials, excluding samples less than the
limit of detection, was 0.37 ppm. Two processing studies were also performed
for tomatoes. Residues were found to concentrate in puree and paste.
Concentration factors were determined to be 2.2 for puree and 3.25 for paste.
These data have been reviewed by EPA and support time-limited tolerances of
1.0 ppm in tomato fruit, 2.0 ppm in puree, and 3.0 in paste. Valent has agreed
to conduct four additional residue trials in growing region 10 as a condition
of registration in order to meet recent Agency guidance for distribution of
crop field trials across the United States.
In 12 field trials, alfalfa was treated with two post-emergent applications of
0.25 lb. a.i./A each. Alfalfa was harvested approximately 15 to 20 days after
each application. Forage samples were taken immediately after cutting and hay
samples were dried in the field for 1 to 10 days before being collected.
Trials were performed in EPA growing regions 1, 5, 7, 10 and 11. Residues for
individual forage samples, treated with either one or two applications, ranged
from 0.13 ppm to 5.7 ppm. The highest average field trial (HAFT) residue was
5.4 ppm. Hay sample residues ranged from 0.45 ppm to 9.2 ppm. The HAFT residue
was 8.9 ppm. These data have been reviewed by the EPA and support tolerances
of 6.0 ppm in alfalfa forage and 10.0 ppm in hay.
In 8 field trials, peanuts were treated with two post-emergent applications of
0.25 lb. a.i./A each approximately 14 days apart and harvested approximately
40 days after the last application. Trials were performed in EPA growing
regions 2, 3, and 8. Harvested peanuts were dried in the field for 3 to 11
days after which peanuts and peanut hay were sampled. Residues for individual
peanut nutmeat samples ranged from < 0.05 ppm to 2.7 ppm. The highest average
field trial (HAFT) residue was 1.75 ppm. The average residue value for all
trials, excluding samples less than the limit of detection, was 0.94 ppm.
Residues in peanut hay ranged from 0.22 ppm to 2.6 ppm with a HAFT residue of
2.55 ppm. A processing study was also performed for peanuts and residues were
found to concentrate in meal with a concentration factor of 3.0. These data
have been reviewed by the EPA and support tolerances of 3.0 ppm in peanut
nutmeat, 3.0 ppm in peanut hay, and 5.0 ppm in peanut meal. Valent has agreed
to conduct four additional residue trials in growing region 2 as a condition
of registration in order to meet recent Agency guidance for distribution of
crop field trials across the United States.
In 9 field trials, dry beans were treated with two post-emergent applications
of 0.25 lb. a.i./A each approximately 14 days apart and harvested
approximately 30 days after the last application. Trials were performed in EPA
growing regions 5, 7, 9, 10, and 11. Residues for individual dry bean seed
samples ranged from 0.58 ppm to 1.6 ppm. The highest average field trial
(HAFT) residue was 1.6 ppm. The average residue value for all trials,
excluding samples less than the limit of detection, was 0.99 ppm. These data
have been reviewed by the EPA and support a tolerance of 2.0 ppm for dry bean
seeds. Valent has agreed to conduct three additional residue trials in growing
region 5 as a condition of registration in order to meet recent Agency
guidance for distribution of crop field trials across the United States.
B. Toxicological Profile
1. Acute toxicity. Clethodim Technical is slightly toxic to animals following
acute oral (Toxicity Category III), dermal (Toxicity Category IV), or
inhalation exposure (Toxicity Category IV under current guideline
interpretation). Clethodim is a moderate eye irritant (Category III), a severe
skin irritant (Category II), and does not cause skin sensitization in the
modified Buehler test in guinea pigs. In addition, an acute oral no-observed
effect level (NOEL) has been determined in rats to be 300 mg/kg. Since this
NOEL is significantly higher than the lowest chronic NOEL of 1 mg/kg/day,
chronic exposures are expected to be of the most concern and this summary will
focus on repeated exposures.
2. Genotoxicity. Clethodim Technical did not induce gene mutation in microbial
in vitro assays. A weak response in an in vitro assay for chromosome
aberrations was not confirmed when clethodim was tested in an in vivo
cytogenetics assay up to the maximally tolerated dose level, nor was the
response observed in vitro using technical material of a higher purity. No
evidence of unscheduled DNA synthesis was seen following in vivo exposure up
to a dose level near the LD50 (1.5 g/kg). This evidence indicates that
clethodim does not present a genetic hazard to intact animal systems.
3. Reproductive and developmental toxicity. No reproductive toxicity was
observed with Clethodim Technical at feeding levels up to 2,500 ppm.
Developmental toxicity was observed in two rodent species, but only at
maternally toxic dose levels. In rats, the developmental NOEL was 300
mg/kg/day while the maternal toxicity NOEL was only 150 mg/kg/day. In rabbits,
the developmental NOEL was 300 mg/kg/day and the maternal NOEL was only 25
mg/kg/day. Thus, Valent believes that clethodim should therefore not be
considered a reproductive or developmental hazard.
4. Subchronic toxicity. High doses of Clethodim Technical cause decreased body
weights, increased liver size (increased weight and cell hypertrophy), and
anemia (decreased erythrocyte counts, hemoglobin, or hematocrit) in rats and
dogs. No observable effect levels have been determined to be 100 mg/kg/day for
a 4-week dermal study in rats, 200 to 1,000 ppm for 4- or 5-week feeding
studies in rats or mice, 500 ppm in a 13-week feeding study in rats, and 25
mg/kg/day in a 90-day oral study in dogs.
5. Chronic toxicity and oncogenicity. In chronic studies conducted in rats,
mice, and dogs, compound-related effects noted at high doses included
decreased body weight, increased liver size (liver weight and hypertrophy),
and anemia (decreased hemoglobin, hematocrit, and erythrocyte count). Bone
marrow hyperplasia was observed in dogs at the highest dose tested. No
treatment-related increases in incidence of neoplasms were observed in any
study. Chronic NOELs were 200 ppm for an 18-month feeding study in mice and
500 ppm for a 24-month study in rats. The lowest NOEL is from the 1-year oral
dog study and is 1 mg/kg/ day clethodim technical. Based on this study and a
100-fold safety factor, the Reference Dose (RfD) for clethodim was determined
to be 0.01 mg/kg/day. Valent believes that Clethodim is not carcinogenic.
6. Rat metabolism. The in vivo metabolism of clethodim in rats was tested at a
high dose (468 mg/kg), low dose (4.4 mg/kg), and a low dose (4.8 mg/kg)
following 14 days of treatment with Clethodim Technical. A single oral dose of
[14C]-clethodim was given to each rat and expired carbon dioxide and excreta
were collected over the next two and seven days, respectively, to determine
radio-label recovery. Several organs and tissues, and the remaining carcass,
were collected after sacrifice to determine radio-label recovery. In all
treatment groups, nearly all of the radio-label was eliminated in the urine
(87-93%), feces (9-17%), and carbon dioxide (0.5-1%) and less than 1% of the
dose was recovered in the organs and tissues after seven days.
Elimination was rapid as most of the recovered dose was eliminated within 48
hours. The low dose groups eliminated clethodim slightly faster than the high
dose group, and repeated exposure to clethodim prior to radio-label dosing did
not affect the rate of elimination or distribution of recovered radio-label.
There were no apparent sex differences with respect to elimination or
distribution of metabolites.
The primary excretory metabolites were identified as clethodim sulfoxide (48-
63%), clethodim S-methyl sulfoxide (6-12%), clethodim imine sulfoxide (7-10%),
and clethodim 5-hydroxy sulfoxide (3-5%). Minor metabolites included clethodim
oxazole sulfoxide (2-3%), clethodim trione sulfoxide (1%), clethodim (1%),
clethodim 5-hydroxy sulfone (0.3-1%), clethodim sulfone (0.1-1%), aromatic
sulfone (0.2- 0.7%), and S-methyl sulfone (0-0.4%).
7. Dermal penetration. The dermal penetration of SELECT 2 EC Herbicide, the
end-use product, was tested on unabraded, shaved skin of rats. Single doses of
approximately 0.05, 0.5, and 5.0 mg of radio- labeled (14C-clethodim) SELECT 2
EC Herbicide, were applied topically to 10 cm2 sites on the dorsal trunk.
After 2, 10, or 24 hours, urine, feces, volatiles, scrubbings of the skin,
skin at treatment site, blood, several tissues, and the carcass were collected
and counted for radioactivity. Clethodim was found to be slowly absorbed
through the skin in a time-dependent manner. The percent of dose absorbed
increased with length of exposure and decreased with increasing dose. Ten-hour
absorption rates ranged from 7.5% to 30.0%. Most of the absorbed material was
found in the urine and carcass, and most of the unabsorbed material was found
in the skin scrubbings indicating that material was still on the skin surface.
8. Metabolite toxicity. Two metabolites of clethodim, clethodim imine sulfone
(RE-47719) and clethodim 5-hydroxy sulfone (RE-51228), have been tested in
toxicity screening studies to evaluate the potential impact of these
metabolites on the toxicity of clethodim. In general, these metabolites were
found to be less toxic than Clethodim Technical for acute and oral toxicity
studies; reproduction and teratology screening studies; and several
C. Aggregate Exposure
1. Dietary exposure--a. Food. Clethodim is approved for use in the production
of commercial agricultural crops including cotton, soybeans, sugar beets, and
onions (dry bulb). Dietary exposures are expected to represent the major route
of exposure to the public. Since chronic exposures are of more concern than
acute exposures for clethodim, this summary will focus primarily on chronic
issues. Chronic dietary assessments for clethodim have been conducted recently
by EPA and Valent to address the new tolerances proposed for tomato, alfalfa,
peanut, and dry bean commodities.
In the EPA assessment (memo from Brian Steinwand dated June 28, 1996),
anticipated residues were used for soybean, cotton, and animal commodities.
For all other crops, tolerance values were used which overestimate potential
exposure. The assessment assumed 100% of all crops were treated with clethodim
which also overestimates exposure. The results of this conservative assessment
are summarized in the Safety Determination section of this document and
indicate that chronic dietary exposures for existing and proposed uses of
clethodim are less than the reference dose.
In Valent's assessment, anticipated residues were used for all crop and animal
commodities. Anticipated residue levels were the mean levels found in crop
field trial data after treatment with the maximum recommended rate and
harvested at minimum allowable intervals. These values are, therefore,
slightly conservative. An assessment was performed assuming 100% of crop
treated (still conservative) as well as assuming a more realistic percent of
crop treated based on market survey data for existing uses or market
projections for proposed uses. Adjusting for percent of crop treated is
justified because most of treated commodities are combined in central
locations and broadly distributed to the public, none of the clethodim
tolerances or uses are limited to specific regions in the United States, and
we are primarily concerned with chronic dietary exposure which minimizes the
variance of single serving residues. The results of these more realistic
assessments are summarized in the Safety Determination section of this
document and indicate that chronic dietary exposures for existing and proposed
uses of clethodim are well below the RfD in either case.
b. Drinking water. Since clethodim is applied outdoors to growing agricultural
crops, the potential exists for clethodim or its metabolites to leach into
groundwater. Drinking water, therefore, represents a potential route of
exposure for clethodim and should be considered in an aggregate exposure
Based on available studies used in EPA's assessment of environmental risk for
clethodim (memo from E. Brinson Conerly dated June 26, 1990), clethodim itself
was classified as mobile in soil, but very non-persistent, representing a
minimal groundwater concern. Metabolites of clethodim were also classified as
mobile, but are slightly more persistent (half-lives up to 30 days versus up
to 3 days for parent). Regarding clethodim metabolites, the Agency concluded
that the "potential for groundwater contamination may be somewhat higher than
for clethodim but would still be expected to be relatively low in most cases
due to their moderately low persistence".
There is no established Maximum Concentration Level for residues of clethodim
in drinking water under the Safe Drinking Water Act. Based on this
information, Valent believes that clethodim appears to represent an
insignificant risk for exposure through drinking water.
2. Non-dietary exposure. Clethodim is currently approved for the commercial
production of agricultural crops including soybeans, cotton, sugar beets,
onions, and ornamental plants as well as for use on non- crop areas. The new
uses proposed in this notice of filing are all agricultural crops. While there
is a potential for clethodim to be used in non-crop areas (e.g. around parks
and rights-of-way) where the public does spend some time, the likelihood of
significant exposure is very small. First, this grass herbicide cannot be
sprayed on lawns where the public does spend significant amounts of time, but
instead must be used where there is no crop or around ornamental plants that
are tolerant to the chemical. The public does not spend significant amounts of
time in these areas. And second, clethodim is not persistent in the
environment so the potential for public exposure is short term. Therefore,
Valent believes that the potential for non-occupational exposure to the
general public, other than through the diet or drinking water, is
D. Cumulative Effects
There is one other pesticide compound registered in the United States,
sethoxydim, which is structurally related to clethodim and has similar effects
on animals. Sethoxydim is approved for use on a variety of agricultural crops,
in non-crop areas, and around the home. This chemical should be considered in
an aggregate exposure assessment along with clethodim. Dietary exposure is
expected to represent the major route of exposure for sethoxydim as well as
The RfD for sethoxydim is 0.09 mg/kg/day based on the 1-year dog feeding study
NOEL and a 100-fold safety factor. This in on the same order of magnitude as
clethodim, 0.01 mg/kg/day, which is also based on a 1-year dog study and a
100-fold safety factor.
A discussion of the cumulative effects from clethodim and sethoxydim exposures
is presented below in the Safety Determination section.
E. Safety Determination
1. U.S. population. Using the dietary exposure assessment procedures described
above for clethodim, chronic dietary exposures resulting from existing and
proposed uses of clethodim were compared to the RfD of clethodim. In the EPA's
conservative analysis (using anticipated residues for some crops and 100% of
all crops treated), the total dietary exposure will occupy 39.4% of the RfD
for the U.S. population. The highest exposure group is children aged 1 - 6
years, where exposure will occupy 84.1% of the RfD. In Valent's conservative
assessment (using anticipated residues and assuming 100% treated for all
crops), exposure for the U.S. population would occupy 13.5% of the RfD and
non-nursing infants (< 1 year) are most highly exposed with total exposure
occupying 29.1% of the RfD. In Valent's realistic analysis (using anticipated
residues and estimated percent of crop treated for all crops), exposure for
the U.S. population would occupy only 0.6% of the RfD and non-nursing infants
would be at only 1.5% of the RfD.
For sethoxydim, recent EPA dietary assessments have been performed in
conjunction with tolerance approvals using the very conservative assumptions
of tolerance values and 100% of crop treated for all crops. In a Proposed Rule
published in the Federal Register dated February 29, 1996 (61 FR 7764; FRL-
5351-8) the EPA estimated that exposure to all existing and proposed
tolerances for sethoxydim would occupy 37.7% of the sethoxydim RfD for the
U.S. population and 74.3% of the RfD for the most exposed subpopulation of
children aged 1 to 6 years. A more realistic assessment utilizing anticipated
residues and percent of crop treated will certainly reduce exposure by a large
amount as with clethodim.
Since clethodim and sethoxydim have similar toxicological effects in mammals,
the contributions to the individual RfDs should be considered in an aggregate
exposure assessment. The EPA generally has no concern for exposures below 100%
of the RfD because the RfD represents the level at or below which daily
aggregate exposure over a lifetime will not pose appreciable risks to human
health. Based on the very conservative assumptions in the EPA analyses,
aggregate exposures would exceed 100% if the contributions for these two
chemicals were summed directly. However, reliable information is not available
to indicate that directly summing the percent of RfD for these two chemicals
is the most appropriate thing to do. In addition, as can be seen by the Valent
assessments using anticipated residue and percent of crop treated values, both
well-accepted Agency practices, realistic exposures are lower by about an
order of magnitude. Similar reductions would be expected for sethoxydim since
actual residues will be lower than tolerance levels and percent of crop
treated values will likely be similar to those for clethodim since they both
compete for the same post-emergence grass herbicide market. Valent believes
that it is therefore very likely that aggregate dietary exposure will be well
below the acceptable level of 100% of the RfD and probably well below 10%.
Unfortunately, Valent does not have access to appropriate values for
anticipated residues or percent of crop treated for sethoxydim and cannot
provide an estimate of realistic dietary exposure.
Regarding drinking water exposures, sethoxydim is similar to clethodim
representing a minimal risk for leaching into groundwater due to its rapid
degradation in the environment. There is no established Maximum Concentration
Level for residues of sethoxydim in drinking water under the Safe Drinking
Regarding non-occupational exposures, sethoxydim is registered for use in non-
crop areas and around the home and may have some potential for exposure to the
general public. However, as discussed for clethodim, sethoxydim cannot be
applied to grass where public contact is expected and sethoxydim is not
persistent in the environment. Valent expects that non-occupational exposures
to the public are therefore expected to be minimal for sethoxydim.
In summary, Valent expects that dietary exposure for clethodim and sethoxydim
are each expected to occupy less than 10% of their RfD's when anticipated
residue levels and percent of crop treated values are considered. Exposures
through the drinking water or other non- occupational routes are expected to
be minimal. Collectively, Valent believes that the aggregate risks associated
with the uses of these two chemicals is small and demonstrates a reasonable
certainty of no harm to the public.
2. Infants and children. As discussed above, dietary exposure for clethodim
and sethoxydim is greatest for children ages 1 to 6 years or non- nursing
infants less than 1 year old. However, using a realistic approach to
estimating exposures, exposures are expected to be below 10% of the RfD for
each chemical even for infants and children. The databases for clethodim and
sethoxydim are complete relative to current pre- and post-natal toxicity
testing requirements including developmental toxicity studies in two species
and multi-generation reproduction studies in rats. Reproduction and
developmental effects have been found in toxicology studies for clethodim and
sethoxydim, but the effects were seen at levels that were also maternally
toxic. This indicates that developing animals are not more sensitive than
adults. FQPA requires an additional safety factor of up to 10 for chemicals
which represent special risks to infants or children. Clethodim and sethoxydim
do not meet the criterion for application of an additional safety factor for
infants and children. Valent believes that this demonstrates a reasonable
certainty of no harm to children and infants from the proposed uses of
3. International tolerances. Although some have been proposed, there are no
Canadian, Mexican, or Codex tolerances or maximum residue limits established
for clethodim on tomatoes, alfalfa, peanuts, or dry beans. There are no
conflicts between this proposed action and international residue limits.
