CFR Part 402).  Until that species-specific analysis is completed, the
risk mitigation measures being implemented through this RED will reduce
the likelihood that endangered and threatened species may be exposed to
sodium chlorate at levels of concern.  EPA is not requiring specific
sodium chlorate label language at the present time relative to
threatened and endangered species.  If, in the future, specific measures
are necessary for the protection of listed species, the Agency will
implement them through the Endangered Species Protection Program.

           D.         Tolerance Reassessment Summary

Table 24 summarizes the reassessment of the sodium chlorate tolerance
exemptions pending a safety finding can be made for sodium chlorite.  40
CFR must be updated to reflect the tolerance exemptions in the table
below.  The tolerance exemptions listed in 40 CFR must be reorganized in
order to: (i) incorporate the recommendations made by the Agency
concerning the sodium chlorate residues of concern that need to be
regulated for plant and animal commodities; (ii) include tolerance
exemptions that are needed to cover sodium chlorate residues of concern
in/on the raw agricultural commodities and processed commodities of
rotational crops; and (iii) conform with the requirements of FQPA.

Existing Exemptions

	Sodium chlorate is currently registered for preharvest and foliar
applications as a defoliant or desiccant to the following food/feed
crops:  beans, corn, cotton, flax, guar, chili peppers, potatoes, rice,
safflower, sorghum (grain), southern peas (i.e., cowpeas), soybeans, and
sunflowers.

	Sodium chlorate exemptions under 40 CFR 180.1020(a) from the
requirement of a tolerance should be amended as follows to: (1) specify
defoliant and desiccant use only, (2) specify use on crops rather than
raw agricultural commodities, and (3) include an exemption for wheat
(grain).

40 CFR 180.1020(a) Sodium chlorate is exempt from the requirement of a
tolerance for residues when used as a defoliant or desiccant in
accordance with good agricultural practice on the following crops:  Bean
(dry, seed), Corn (field, stover), Corn (field, forage), Corn (field,
grain), Corn (sweet, stover), Corn (pop, stover), Corn (pop, grain);
Corn (sweet, forage), Cotton (undilented seed), Flax (seed), Guar
(seed), Peas (southern, seed), Peppers (nonbell), Potatoes, Rice
(grain), Rice (straw), Safflower (seed), Sorghum (grain, grain), Sorghum
(grain, stover), Sorghum (grain, forage), Soybean (seed), and Sunflower
(seed).

	Under 40 CFR 180.1020(b), a time-limited exemption from the requirement
of a tolerance is established for residues of the defoliant/desiccant in
connection with use of the pesticide under section 18 emergency
exemptions granted by EPA.  This exemption was granted for wheat and
expires 12/31/06.  The use of sodium chlorate on wheat is also addressed
herein with the intention to convert the time-limited exemption status
to a permanent exemption from the requirement of a tolerance under 40
CFR.1020 (a).  The proposed use rate is for a single application of
sodium chlorate to wheat at 6 lbs ai/A with a 3-day PHI.

Needed Exemptions

	Sodium chlorate (873301) as an inert ingredient in herbicide
formulation products can be applied professionally to agricultural
(corn, guava, macadamia nuts, sorghum grain, sugarcane, wheat),
commercial (non-agricultural), and residential sites.  These
conventional pesticide products contain < 1 % sodium chlorate and can be
applied at rates no greater than 0.07 lb (as sodium chlorate) per acre.

	Potassium chlorate (900583) as an inert ingredient in fungicide
products can be applied in poultry premises.  These conventional
pesticide products contain < 20% potassium chlorate and can be applied
at rates not greater than 0.01 lb (as potassium chlorate) per 500 ft3.
See Table 25 below for the tolerance exemptions needed for sodium
chlorate.

Codex/International Harmonization

	There are no Codex maximum residue limits (MRLs) for sodium chlorate.

E.	Regulatory Rationale

	The following is a summary of the rationale for managing risks
associated with the use of sodium chlorate for sodium chlorate products
to be eligible for reregistration.  Where labelling revisions are
warranted, specific language is set forth in Table 28 of Section V.

		1.	Human Health Risk Management

			a.	Dietary (Food) Risk Mitigation

Acute Dietary (Food) Risk

	No acute dietary endpoint was selected for sodium chlorate, because
effects attributable to a single dose were not seen in the available
data.  Therefore, dietary acute risk is not of concern to the Agency,
and no mitigation measures are required to address acute risk.

Chronic Dietary (Food) Risk

The chronic dietary risk assessment for food only is below the
Agency’s level of concern (LOC) for the general US population and all
population subgroups.  The most highly exposed population subgroup,
children 1-2 years of age, was at 28% of the chronic Population Adjusted
Dose (cPAD).  Since this is less than 100% of the cPAD, no mitigation is
needed.

b. 	Residential Risk Mitigation

All residential (non-occupational) handler and post-application risk
estimates for inorganic chlorates, as active or inert ingredients in
conventional pesticide products used in residential environments, are
below the Agency’s LOC (i.e., MOEs are greater than the LOC of 100).
The handler inhalation MOEs ranged from 370 to 710,000.  The
post-application combined MOE (for inert ingredients) was 23,000 for all
potential routes of exposure to children; therefore, no residential
mitigation is necessary.

			c.	Aggregate Risk Mitigation

As discussed in Section III of this RED, aggregate risk refers to the
combined risk from food, drinking water, and residential exposures.
Aggregate risk can result from one-time (acute), short-term and/or
chronic exposures.

Acute Aggregate Risk

For sodium chlorate, acute aggregate risk was not assessed, because
effects attributable to a single dose were not seen in the available
data.  Therefore, acute aggregate risk is not of concern to the Agency.

Short-Term Aggregate Risk

Short-term aggregate risk was quantitatively assessed for adults only,
using the highest exposure scenario (inhalation exposure while applying
granules by hand) resulting in an MOE of 324.  Short-term aggregate risk
for children was qualitatively assessed and not of concern to the Agency
because the short-term residential risk to children from the use of
sodium chlorate as an inert is minimal (MOE of 23,000).  All short-term
aggregate risks are below the Agency’s LOC (i.e., MOEs are greater
than 100); therefore, no mitigation is necessary.

Chronic Aggregate Risk

Since no chronic residential (non-dietary) exposure scenarios have been
identified for sodium chlorate, the chronic aggregate risk assessment
considers exposure only through food and drinking water.  The Agency
believes there is no chronic risk of concern, for the US general
population or any subpopulation group, for the reasons described below.

The chronic dietary (water only) risk assessment for chlorate in
drinking water, using the highest annual average concentration from ICR
data of 0.69 mg/L, is below the Agency’s level of concern for the
general US population and all subgroups except all infants <1 year of
age.  The highest exposed population subgroup, all infants <1 year of
age, was 159% of the cPAD.  Using the 90th percentile annual average
concentration of 0.24 mg/L, the chronic dietary (water only) risk for
all infants <1 year of age was <55% of the cPAD; using the median annual
average concentration estimated at 0.11 mg/L, estimated chronic risk
from drinking water was 25% of the cPAD.  The contribution of exposure
from food sources increases total dietary risk (food + drinking water)
to 174% of the cPAD for infants <1 year of age at the highest annual
average, but remains below EPA’s level of concern at the 90th
percentile (70% of the cPAD).

		Data on the occurrence of chlorate ion in drinking water were
available from two primary sources:  the Information Collection Rule
(ICR) Auxiliary 1 Database, Version 5.0, and the AwwaRF research study
on the control of chlorate ion in hypochlorite solutions.  The most
extensive data are from the ICR where source water and drinking water
were monitored for chlorate ion between July 1997 and December 1998.
Water systems serving a population of at least 100,000 were required to
monitor for chlorate ion at treatment plants using chlorine dioxide or
hypochlorite solutions in the treatment process.  Although the ICR water
systems represent roughly one percent of the total number of drinking
water systems in the United States, these systems serve almost 60% of
the population.  Under the ICR, plants using chlorine dioxide collected
monthly samples of the source water entering the plant, the finished
water leaving the plant, and at three sample points in the distribution
system (near the first customer, an average residence time, and a
maximum residence time).  Samples were taken throughout the distribution
systems for plants using chlorine dioxide, since the concentration of
chlorate is expected to change within the system due to the conversion
of chlorine dioxide to chlorate that occurs in the presence of chlorine.
 Plants using hypochlorite solutions were required to collect quarterly
samples of the water entering and leaving the plant.

		The AwwaRF data consists of samples collected in 1993 by 111 water
treatment plants using hypochlorite.  The majority of the systems in the
AwwaRF project serve populations less than 100,000, and a large subset
of those serve populations less than 10,000.  Samples of source water,
hypochlorite solution, and finished drinking water from 111 of water
systems were analyzed for chlorate.  Only one set of samples was
collected for each system, and samples were not collected at plants
using chlorine dioxide.  Furthermore, the background information on the
111 water systems that participated in the project was not linked to the
samples they provided; therefore, the chlorate concentrations can not be
directly related to the size of the water system or type of hypochlorite
solution in use.

		The AwwaRF samples were typically found to have higher concentrations
of chlorate than the samples collected from the larger ICR systems.  The
difference in chlorate concentrations could be the result of a number of
factors, such as: 1) The AwwaRF data represents a single point in time,
while the ICR data reflects an average over 18 months; 2) most of the
AwwaRF samples were collected from utilities that served populations of
less that 100,000, while all of the ICR samples were from utilities
serving at least 100,000; and 3) hypochlorite treatment plant practices
may have changed between when the AwwaRF samples were collected (1993)
and the ICR samples were collected (1997-1998).  When the AwwaRF study
was conducted, utilities were just becoming aware of the formation of
chlorate ion in hypochlorite solutions.  The AwwaRF project was funded
in order to provide water treatment facilities with information on how
to minimize the formation of chlorate byproduct; it is possible that
facilities consequently revised their treatment practices.

		The ICR Database was considered the more appropriate source for
estimating exposure averages from individual water treatment plants,
primarily because the AwwaRF study is a less robust data set consisting
of only one sample per utility, whereas the ICR database collected
multiple samples over an 18 month period, from plants using both
hypochlorite and chlorine dioxide.  Both the AwwaRF study and the ICR
data reveal high concentrations of chlorate ion to be a local situation
affecting a relatively small number of systems.  Of the ICR data set,
only four water treatment plants had average chlorate ion concentrations
that exceeded the Agency’s level of concern (i.e., 370 ppb or 0.37
mg/L, for the infant subpopulation) including one treatment plant
serving 218,000 people that had the highest annual average (0.69 mg/L).
Of the four plants that exceeded, two treatment plants used chlorine
dioxide, and two used hypochlorite.  The total number of people served
by the four water treatment plants exceeding 0.37 mg/L represents 0.5%
of the ICR population, or 621,000 people.  All three exposure ranges
(highest average, 90th percentile, and median) are presented in Section
III.  Only the “highest average” exposures resulted in potential
chronic risk estimates that were above the Agency’s LOC, and only for
infants.  Over 99% of the ICR population receives finished water below
the Agency’s LOC of 0.37 mg/L.

The chlorate ion (ClO 3-) is a disinfection byproduct (DBP) of water
treatment which can be formed during the on-site generation of chlorine
dioxide (ClO 2-), the decomposition of chlorine dioxide in the water
treatment system, the decomposition of hypochlorite (OCl-) during
storage, and the interaction of chlorite ion and free chlorine.
Treatment of public water supplies is necessary to kill pathogens that
may exist in the drinking water, such as cholera, typhoid, and
dysentery.  Outbreaks of these diseases decreased significantly when
disinfection of the water systems was introduced in the early 1900s.
While there are many important public functions of water treatment, the
Agency is taking steps to limit the exposure of chlorate ion as a DBP to
the public.

In order to help reduce potential exposure to chlorate, the Agency’s
Office of Pesticide Programs (OPP), in conjunction with the Office of
Water (OW), is working with the American Water Works Association (AWWA),
the Chlorine Institute, and individual water communities to provide
community water systems with information on Best Management Practices
(BMPs) for use in drinking water treatment.  BMPs may include measures
such as production modifications, operational changes, materials
substitution, materials and water conservation, and other such measures.
 For example, water systems that use hypochlorite solutions can minimize
the levels of chlorate ion by purchasing high quality hypochlorite
solutions and through careful storage during use.  While decomposition
of hypochlorite solutions cannot be avoided, the rate of decomposition
can be managed.  Among the major factors affecting stability are the
following:  concentration of the hypochlorite solution, temperature of
the solution, pH of the solution, and exposure to light sources.  The pH
of the solution should be in the 12 to 13 range to minimize
decomposition.  Hypochlorite solutions should be protected from high
temperatures and sunlight, and storage time should be minimized, both
from the time of manufacture to delivery, and from the time of delivery
to use.  The solutions can also be diluted to control decomposition as
long as the proper pH is maintained and high quality dilution water is
used.  The primary ways in which water systems using chlorine dioxide
can control the levels of chlorate in the finished water is through high
efficiency operation of their chlorine dioxide generators and by
reducing chlorite ion concentrations prior to the addition of free
chlorine.  The BMPs could also include additional training of the water
systems employees on the proper handling of these chemicals.

The Agency believes that sodium chlorate does not constitute a risk of
concern to the general population or any population subgroups, since the
LOC exceedances are associated with a small number of water treatment
facilities and inappropriate treatment practices.  Furthermore, the
Agency anticipates that the community water system outreach strategy
previously discussed will greatly reduce potential drinking water
byproduct exposure.

			d.	Occupational Risk Mitigation

With the consideration of mitigation measures proposed by registrants
and the use of engineering controls (enclosed cockpits or cabs), all
occupational handler risks for the use of inorganic chlorates as an
active or inert ingredient in conventional pesticides are below the
Agency’s LOC (i.e., MOEs are greater than the LOC of 100).  For sodium
chlorate, occupational exposure durations are short- (1-30 days) and
intermediate term (1-6 months) only.  Long-term (> 6 months) exposure is
not expected based on the use pattern for sodium chlorate.
Post-application dermal and inhalation exposures are negligible due to
the chemical’s physical and chemical characteristics as an inorganic
salt.  No significant amount of sodium chlorate is expected to be
absorbed through the skin and the vapor pressure is negligible;
therefore, a post-application exposure assessment was not conducted.

Antimicrobial Uses of Sodium Chlorate

	Risks to handlers treating water systems are below the Agency’s LOC;
therefore, no mitigation measures are necessary.

Agricultural Uses of Sodium Chlorate

 With the exception of aerial applications, for which enclosed cockpits
are required, the handler and flagger MOEs for sodium chlorate’s
agricultural uses are below the Agency LOC at baseline level of
protection (long sleeve shirt, long pants, shoes, and socks).  MOEs
range from 190 (mixing/loading liquids for aerial application on cotton,
corn, et al.) to 3600 (mixing/loading liquids for groundboom application
on ornamental gourds and cucurbits).  Further, the maximum application
rate for use on cotton will be reduced from 7.5 lbs ai/A to 6 lbs ai/A,
with a limitation of one application (except for California, where two
applications will be allowed).  No additional mitigation is required for
occupational risk resulting from the agricultural uses of sodium
chlorate.

Non-agricultural Uses of Sodium Chlorate

 The Agency’s review of sodium chlorate labels, in addition to
discussions with registrants, indicates that the current
non-agricultural use labels are not reflective of actual use practices.
The non-agricultural use labels currently allow for larger application
rates than are necessary for efficacy, as well as allow for unlimited
treatment areas, although sodium chlorate’s non-agricultural
formulations are typically used as spot treatments.

Mitigation measures for sodium chlorate’s non-agricultural uses to be
included on product labels will reduce risk from the occupational and
ecological exposures to sodium chlorate.  The registrants have agreed to
the following non-agricultural use mitigation measures for sodium
chlorate:

All non-agricultural uses will be limited to spot treatments only (with
the exception of the granular formulation for use under asphalt,
although this use will be limited to an 8000 ft2 treatment area).  The
uses limited to spot treatments include, but are not limited to:
building perimeters (including farm buildings), driveways, parking lots,
fence rows, military installations, pipelines, railroads, lumberyards,
industrial sites (transformers, generators, utility poles, etc.), tennis
court perimeters, picnic areas, bleachers, cemeteries, fuel tanks,
airport runways, helo pads, wood decks, guard rails, highway medians,
sidewalks/walkways, vacant lots, fire hydrants, recreational areas, and
other similar areas.

Use on rights-of-way and ditch banks will be cancelled.

The label will specify a maximum application rate of 0.9 lb/Ai/100 ft2

The Agency generally converts application rates to a per acre basis for
assessment purposes; therefore, the rate of 0.9 lb/Ai/100 ft2 is
referred to as 392 lb/Ai/A in this document.  However, because all
non-agricultural uses will be limited to spot treatment applications
only, all 392 pounds of a.i. will not be applied on any one given acre.
Assuming only one acre is considered for treatment, sodium chlorate can
only be applied to up to 8000 ft2, which equates to up to approximately
78 lbs ai being applied to any given acre.  It is assumed that more than
one acre will be treated.

Risk calculations have been developed to better represent the current,
actual use pattern for sodium chlorate, and occupational risk was
reassessed based on the revised use pattern discussed above (i.e.,
application rates, target sites, and amount treated).  Following is a
summary of the Inorganic Chlorates: Addendum to the Occupational and
Residential Exposure Assessment for the Reregistration Eligibility
Decision (RED) Document, dated May 18, 2006.

All data, factors, and assumptions used in the addendum are the same as
those used in the previous occupational risk assessment.  These include,
but are not limited to:

body weight (70 kg representing adult handlers);

toxicological endpoints (short-/intermediate-term oral NOAEL of 30
mg/kg/day) and uncertainty factors (Level of Concern (LOC) for the MOE
is 100);

application rates (in lb/Ai/A – presented as a range to encompass the
various registered products); and,

unit exposures (from PHED and/or ORETF database, both of which have
undergone appropriate review by the Human Studies Review Board).

However, factors regarding application equipment used and daily area
treated were revised based on updated use pattern information and
proposed product label revisions.  The previous assessment, summarized
in Section III, was based on applications with larger, industrial
equipment such as tractor spreaders or groundboom sprayers.  As a result
of mitigation measures agreed to by the technical registrants, sodium
chlorate applications to non-agricultural areas (i.e., building
perimeters, ditch banks, bleachers, airport runways, vacant lots, fire
hydrants, or as a pre-paving treatment) will be limited to
“handheld” equipment such as rotary spreaders and pump or power
sprayers.  In addition, the standard Agency assumptions for the amount
applied per work day is based on the application equipment used to
determine exposure and risk.  Since submitted information indicates that
no more than 8,000 ft2 of an acre (approximately 20%) will be treated
with sodium chlorate, the Agency has adjusted the standard assumptions
for acres treated per day to reflect this spot treatment-type scenario.

Based on the revised assumptions for the daily area treated and on
application methods suitable for spot treatments (low-pressure handwand
sprayers, belly grinders, push-type spreaders), the risks for all
non-agricultural uses, even at the currently labeled application rate
(523 lbs ai/A instead of 392 lb/Ai/A), are below the Agency LOC.  The
higher application rate of 523 lb/Ai/A was used, because at the time the
Inorganic Chlorates: Addendum to the Occupational and Residential
Exposure Assessment for the Reregistration Eligibility Decision (RED)
Document, dated May 18, 2006, was prepared, the 392 lb/Ai/A maximum
application rate mitigation measure was not yet finalized.  The
mitigation measures outlined above reduce the occupational risk from all
of sodium chlorate’s non-agricultural uses to below the Agency’s
level of concern at baseline level of protection (long sleeve shirt,
long pants, shoes, and socks).  The risks based on the revised
non-agricultural use patterns for sodium chlorate are summarized in
Table 26 below.

 		2.	Non-Target Organism (Ecological) Risk Management

	Chlorate is a strong oxidizer and may be reduced to other chemically
related species under some environmental conditions.  The extent and
rate to which this occurs will depend on the redox chemical species
(including organic matter) in the water or soil.  Extensive spatial and
temporal variability is expected for the reactions of chlorate in the
environment.  However, the currently available simulation models do not
allow for a quantitative evaluation of the potential exposure levels of
each the reduced products of chlorate (i.e., speciation and
predominance) and how fast these chemical species may form.  Therefore,
there is a high degree of uncertainty in the ecological exposure and
risk assessment.  This is important because a reduction product of
chlorate (chlorite) is expected to be more toxic to most aquatic and
terrestrial species, particularly aquatic invertebrates.

			a.	Terrestrial Organisms

					1.	Birds and Mammals

	EPA’s screening-level risk assessment, based on currently labelled
maximum application rates, for both agricultural and non-agricultural
uses for sodium chlorate, suggests potential acute and chronic risk for
birds

Avian Acute Risk

	Avian acute risk was not calculated, since no mortality or signs of
toxicity were observed in the submitted subacute or acute toxicity
studies at concentrations that are above the limit for these types of
studies; therefore, acute risk to birds is not expected.  However, the
Agency cannot preclude acute or subacute risk from the non-agricultural
uses.  Some labels have maximum application rates up to 1032 lbs ai/A,
and the ecological assessment for risk from non-agricultural uses was
based on rates ranging from 52 to 523 lbs ai/A, with corresponding EECs
from 12,500 and 125,000 ppm, respectively.  These EECs are approximately
2.5 to 25-fold higher than the highest concentration tested in the
subacute bird toxicity studies.  The non-agricultural use mitigation
outlined above, including the reduction of the maximum application rate
to 392 lbs ai/A, and a limitation to spot treatments only (except for
use under asphalt, although this use is limited to no more than an 8000
ft2 area).  Reducing the maximum application rate from 520 lbs ai/A to
392 lbs ai/A will reduce the estimated environmental concentrations of
chlorate by approximately 25%.  Further, to the extent that there is any
potential acute risk to birds from the non-agricultural uses, the fact
that these uses will result in small contiguously treated areas could
limit avian exposure.

Avian Chronic Risk

	 Maximum chronic RQs, based on EECs derived with 90th percentile
residue estimates from the Kenaga nomogram, exceed the Agency’s avian
LOC of 1.0 for all agricultural uses assessed for birds eating short
grass, tall grass, broadleaf forage, and small insects.  Chronic RQs
based on EECs derived with mean residue estimates from the Kenaga
nomogram, although not presented in Section III, would be approximately
three times lower for any single application of sodium chlorate.  The
highest agricultural use chronic RQ was 11 (chili peppers/white, Irish
potatoes and the short grass food category).  The second highest RQs
were for cotton (ranging from 10.0 for the short grass food category, to
0.63 for fruits, pods, seeds, and small insects).  Cotton is also by far
the most common agricultural use of sodium chlorate, with approximately
1,900,000 lbs ai applied annually.

	To address the chronic risk to birds from use on cotton, the maximum
application rate will be reduced from 7.5 lbs ai/A to 6 lbs ai/A, and
applications will be limited to a single applications in all states
except California, where a second application will be allowed.  This
mitigation measure will reduce chronic risk to birds from use on cotton
by approximately one- half, with RQs ranging from 5.31 (on the short
grass food category), to 0.33 (on fruits, pods, seeds, and small
insects) for all states except California.  In California, the chronic
avian RQs based on the reduced maximum application rate of 6 lbs ai/A,
and two applications, will be reduced to a range of 8.25 (on the short
grass food category) to 0.52 (on fruits, pods, seeds, and small
insects).

	Chronic avian RQs for sodium chlorate were based on a NOAEC of 271 ppm
from the bobwhite quail chronic reproductive toxicity test.  However,
maximum EECs for a majority of the uses and classes of food items were
also higher than the LOAEC in bobwhite quail of 964 ppm.  At the LOAEC,
reproductive effects occurred, including a 67% reduction in eggs laid
and 64% reduction in number of hatchlings per egg laid.  Therefore, if
actual exposure is equivalent to the maximum values calculated with the
T-REX model, there is a greater certainty that frank reproductive
effects in birds might occur.

	However, the duration of exposure needed to produce reproductive
effects in birds is an uncertainty.  This uncertainty is significant in
the case of sodium chlorate, because as a broad-spectrum herbicide, its
toxic effects on plants are visible within several days.  Since the
vegetation in the treated area will die, it is uncertain whether or not
this vegetation will be attractive to birds as a feed item long enough
for the chronic effects to occur.

Chronic RQs were not calculated for sodium chlorate’s non-agricultural
uses.  However, based on the high application rates and resulting high
potential EECs, risks from sodium chlorate’s non-agricultural uses
could be considerably higher than those described in Section III for the
agricultural uses.  The non-agricultural use mitigation outlined above,
including a reduction in the maximum labeled application rate to 0.9 lbs
ai/100 ft2 (392 lbs ai/A), would reduce the EECs of chlorate by
approximately 25% in the areas treated.  Furthermore, the limitation of
most non-agricultural uses to spot treatments only is expected to reduce
the likelihood that a terrestrial organism will come into contact and
consume all of its diet from a treated area.  However, RQs still exceed
the chronic LOC for birds (1.0).  See the Analysis of proposed changes
to sodium chlorate’s application rates and maximum treated area on
potential ecological risks presented in EFED’s reregistration
eligibility decision (RED) document, dated June 13, 2006 for further
detail.

Mammalian Acute Risk

Acute  tc "

Acute  " \l 4 RQs were not calculated for mammals.  The LD50 from a core
acute oral toxicity study in rats was >5000 mg/kg-bw.  In this study,
10% (1/10) of the rats administered 5000 mg/kg died.  Mortality was not
observed at any other dose.  Therefore, the data were not sufficient to
allow for characterization of the dose-response relationship and the
proximity of the LD50 to 5000 mg/kg-bw is uncertain.  Although RQs were
not calculated for mammals, Tables 17, 18 and 19 in Section III present
a comparison of the body weight adjusted LD50s to EECs for agricultural
spray, and the non-agricultural spray and granular, formulations,
respectively.  These ratios can be used to estimate high-end risk to
exposed mammals.  Risk quotients would be lower than the values in
Section III.

For sodium chlorate’s agricultural uses, all of the mammalian acute
risk estimates are below the Agency’s acute and endangered species LOC
of 1.0 and 0.1, respectively, with the exception of small mammals eating
short grass.  The highest exceedence is for 15 gram mammals eating short
grass (risk ratio = 0.26); therefore, no mitigation is necessary.

For sodium chlorate’s non-agricultural uses, the ratios indicate a
potential acute concern to mammals for both spray and granular
formulations, with the highest ratios calculated for small mammals
(ratios =11 and 33 for spray and granular formulations, respectively).
While the ratios presented in Section III suggest that there could be
acute risk to mammals of all sizes that forage in the area where sodium
chlorate is applied to non-agricultural use sites, the risk was likely
over-estimated, since an LD50 has not been established.  Furthermore, as
previously explained, a reduction in the maximum application rate for
the non-agricultural uses to 392 lbs ai/A would reduce the EEC’s of
chlorate in treated areas by approximately 25%.  Limitation of the
treatments to spot treatments only would be expected to further reduce
the likelihood that a terrestrial organism will come into contact and
consume all of its diet from that area.

Mammalian Chronic Risk

For mammals, the Agency typically evaluates the mammalian reproductive
effects for exposures greater than 30 days.  The interpretation of the
effects seen in the 2-generation rat reproduction toxicity study, used
to derive the mammalian reproduction toxicity endpoint for sodium
chlorate, is difficult in this respect.  While effects were observed at
70 mg/kg-bw and above, the effects are not clearly associated with
reduced reproductive success or survival.  The mammalian reproductive
NOAEC is based on the highest dose tested in this study (500 mg/kg-bw),
although no toxic or reproductive effects were observed at this level.
Therefore, the NOAEC could be higher than 500 mg/kg-bw, which would
result in lower mammalian reproduction risk estimates.  However, the
Agency calculated risk ratios based on the 500 mg/kg-day NOAEL as a
conservative estimate of risk, as presented in Section III.  For the
agricultural uses of sodium chlorate, the chronic mammalian LOC of 1.0
was only slightly exceeded for the smallest weight classes of mammals
for most food items and the largest weight class of mammals feeding on
short grass (RQs range from 2.6 to 0.07).  The mitigation measures
previously outlined for sodium chlorate use on cotton (maximum
application rate reduced from 7.5 lbs ai/A to 6 lbs ai/A, with the
limitation of a single application, except in California, where a second
application will be allowed), will further reduced chronic mammalian
risk.  Furthermore, based on the lack of observed reproductive effects
in the chronic study and the slight LOC exceedances for agricultural
uses, the Agency does not anticipate a chronic risk of concern to
mammals from these uses.

As with the agricultural uses, mammalian reproduction RQs were not
calculated for sodium chlorate’s non-agricultural uses.  However, the
higher application rates for the non-agricultural uses, and the
resulting higher EECs, suggest that the risk for these uses would be
higher than the risk estimates presented for the agricultural uses.
Note that the mammalian reproduction RQs for the agricultural uses of
sodium chlorate, presented in Section III, are a conservative estimate
of risk.  Furthermore, as previously explained, to reduce risk from
sodium chlorate’s non-agricultural uses, the maximum application rate
will be reduced to 0.9 lb/Ai/100 ft2.  This mitigation measure will
reduce the EECs by approximately 25%.  In addition, the limitation to
spot treatments will reduce the likelihood that mammals will come into
contact and consume all of its diet from a treated area.  See the
Analysis of proposed changes to sodium chlorate’s application rates
and maximum treated area on potential ecological risks presented in
EFED’s reregistration eligibility decision (RED) document, dated June
13, 2006, for further detail.

Non-Target Insects

	EPA currently does not estimate RQs for terrestrial non-target insects.
 In addition, the Agency has no toxicity data for sodium chlorate.
Therefore, EPA will require data to address this uncertainty.

				3.	Non-Target Terrestrial Plants

	Based on chlorate’s non-selective mode of action and lack of adequate
toxicity data, the Agency presumes risk to non-target terrestrial plants
at levels above the Agency’s level of concern for all uses.  The risks
to plants cannot be quantified at this time due to lack of data;
however, the Agency will require data to address this uncertainty.

b.	Aquatic Organisms

	1. 	Fish

	There is no acute risk of concern, from either the agricultural or
non-agricultural uses of sodium chlorate, to freshwater or
estuarine/marine fish.  All risk ratios are less than 0.05, which is
below the Agency’s acute LOC of 0.5 and below the acute endangered
species LOC of 0.05.  However, some data suggest that brown trout
(freshwater fish) could be substantially more sensitive than other fish
species tested to chlorate’s toxicity.  It is uncertain if these data
are reliable; therefore, the Agency will require additional testing in
brown trout to address this area of uncertainty.

No chronic fish toxicity studies are available to allow for chronic risk
to fish to be quantified.  Therefore, the Agency will require data to
address this uncertainty.

2. 	Aquatic Invertebrates

For freshwater invertebrates, acute RQs are below the acute LOC of 0.5
and the endangered species acute LOC of 0.05, for both agricultural and
non-agricultural uses of sodium chlorate.  Therefore, acute risk to
freshwater invertebrates is not of concern to the Agency, and no
mitigation is required.

For saltwater invertebrates, the acute risk ratios for sodium
chlorate’s agricultural and nonagricultural uses were below the
Agency’s acute LOC of 0.5, in addition to the endangered species acute
LOC of 0.05 (highest ratio = 0.04 for non-agricultural uses).
Therefore, acute risk to saltwater invertebrates is not of concern to
the Agency.

	Chronic risk to invertebrates (freshwater and saltwater) was not
assessed, since treatment-related effects were not observed at any
concentration in available studies.

				3.	Aquatic Plants

For non-endangered aquatic plants, the Agency’s LOC of 1.0 was not
exceeded for either the agricultural or nonagricultural uses of sodium
chlorate (highest RQ = 0.91 for non-agricultural uses).  Therefore, risk
to non-endangered aquatic plants is not of concern to the Agency.

For endangered aquatic plants, the Agency’s LOC of 1.0 was not
exceeded for sodium chlorate’s agricultural uses (highest RQ = 0.29),
but the LOC was exceeded for sodium chlorate’s non-agricultural uses
(highest RQ = 12.6).  However, the mitigation measures listed above for
the non-agricultural uses of sodium chlorate, including a reduction in
the application rate and treated area, result in a reduction of the
endangered vascular plant RQ from 12.6 to 1.5.  While this is a
significant improvement, it is still above the Agency’s endangered
plant LOC of 1.0.   Furthermore, because of a lack of submitted data,
there is uncertainty remaining on sodium chlorate’s toxicity to
aquatic plants.  The Agency will require data to address this area of
uncertainty.

		3.	 Summary of Mitigation Measures

	The following mitigation measures are necessary for sodium chlorate to
be eligible for reregistration.   These include use restrictions,
voluntary cancellations and/or use deletions, and personal protective
equipment.

Agricultural use mitigation:

Engineering controls (enclosed cockpits) for aerial applications on
agricultural crops.

For cotton, the maximum application rate will be reduced from 7.5 lbs
ai/A to 6 lbs ai/A, and applications will be limited to a single
applications in all states except California, where a second application
will be allowed.

Non-agricultural use mitigation:

All non-agricultural uses will be limited to spot treatments only (with
the exception of the granular formulation for use under asphalt,
although this use will be limited to an 8000 ft2 treatment area).  The
uses limited to spot treatments include, but are not limited to:
building perimeters (including farm buildings), driveways, parking lots,
fence rows, military installations, pipelines, railroads, lumberyards,
industrial sites (transformers, generators, utility poles, etc.), tennis
court perimeters, picnic areas, bleachers, cemeteries, fuel tanks,
airport runways, helo pads, wood decks, guard rails, highway medians,
sidewalks/walkways, vacant lots, fire hydrants, recreational areas, and
other similar areas.

Use on rights-of-way and ditch banks will be cancelled.

The label will specify a maximum application rate of 0.9 lb/Ai/100 ft2.

	To be eligible for reregistration, various use and safety information
will be included in the labeling of all end-use products containing
sodium chlorate.  For the specific labeling statements and a list of
outstanding data, refer to Section V of this RED document.

  SEQ CHAPTER \h \r 1 		1.	 Endangered Species Considerations

	The Agency’s screening level assessment results in the determination
that sodium chlorate will have no acute risks to birds, no acute risks
to fish (freshwater and estuarine/marine), and no acute or chronic risks
to aquatic invertebrates (freshwater and estuarine/marine).

	However, the preliminary risk assessment for endangered species
indicates that RQs exceed endangered species LOCs for chronic risks to
birds (RQs up to 11 for agricultural uses and greater for
non-agricultural uses); acute risks to mammals (RQs up to 33); chronic
risks to mammals (RQs up to 1.2 for agricultural uses and greater for
non-agricultural uses); and risks to aquatic plants (RQs up to 13).
Risks could not be calculated for terrestrial plants and for chronic
risks to fish; however, the Agency will be requiring data.

	Further, potential indirect effects to any species dependent upon a
species that experiences effects from use of sodium chlorate can not be
precluded based on the screening level ecological risk assessment.
These findings are based solely on EPA’s screening level assessment
and do not constitute “may affect” findings under the Endangered
Species Act.

	The Agency has developed the Endangered Species Protection Program to
identify pesticides whose use may cause adverse impacts on endangered
and threatened species, and to implement mitigation measures that
address these impacts.  The Endangered Species Act (ESA) requires
federal agencies to ensure that their actions are not likely to
jeopardize listed species or adversely modify designated critical
habitat.  To analyze the potential of registered pesticide uses that may
affect any particular species, EPA uses basic toxicity and exposure data
developed for the REDs and considers it in relation to individual
species and their locations by evaluating important ecological
parameters, pesticide use information, geographic relationship between
specific pesticide uses and species locations, and biological
requirements and behavioral aspects of the particular species, as part
of a refined species-specific analysis.  When conducted, this
species-specific analysis will take into consideration any regulatory
changes recommended in this RED that are being implemented at that time.

	Following this future species-specific analysis, a determination that
there is a likelihood of potential impact to a listed species or its
critical habitat may result in: limitations on the use of sodium
chlorate, other measures to mitigate any potential impact, or
consultations with the Fish and Wildlife Service or the National Marine
Fisheries Service as necessary.  If the Agency determines use of sodium
chlorate “may affect” listed species or their designated critical
habitat, EPA will employ the provisions in the Services regulations (50
CFR Part 402).  Until that species-specific analysis is completed, the
risk mitigation measures being implemented through this RED will reduce
the likelihood that endangered and threatened species may be exposed to
sodium chlorate at levels of concern.  EPA is not requiring specific
sodium chlorate label language at the present time relative to
threatened and endangered species.  If, in the future, specific measures
are necessary for the protection of listed species, the Agency will
implement them through the Endangered Species Protection Program.

		2.	Spray Drift Management  tc "			2.	Spray Drift Management " \l 4

	The Agency has been working closely with stakeholders to develop
improved approaches for mitigating risks to human health and the
environment from pesticide spray and dust drift.  As part of the
reregistration process, EPA will continue to work with all interested
parties on this important issue.

	From its assessment of sodium chlorate, as summarized in this document,
the Agency concludes that certain drift mitigation measures are needed
to address the risks from off-target drift for sodium chlorate,
including a requirement for medium to coarse droplet size.  Label
statements implementing these measures are listed in the "spray drift
management" section of the label table (Table 28 in Section V of this
RED document.  In the future, sodium chlorate product labels may need to
be revised to include additional or different drift label statements.

	The generic data base supporting the reregistration of sodium chlorate
has been reviewed and determined to be substantially complete.  However,
there are a few data gaps remaining, and these data, presented in Table
27, must be submitted or the Agency may take regulatory action on
registrations of pesticide products containing sodium chlorate.

While the terrestrial field dissipation (835.6100) guideline study may
not be appropriate for sodium chlorate, the Agency is still concerned
about the prolonged use of sodium chlorate on cotton (about 50 years).
Terrestrial field dissipation data are not available for sodium
chlorate, and the guideline requirement for this study was never waived.
 There are some reports that sodium chlorate can be persistent in the
field (ranging from 6 months to 5 years, depending on application rate,
soil type, fertility, organic matter, moisture, and weather conditions).
 Also, several labels report that sodium chlorate is effective for the
control of weeds for up to a year, which indicates that chlorate may
persist for up to a year.  Therefore, the range of persistence of sodium
chlorate in the field remains a major uncertainty in the environmental
fate behavior of this chemical.  Use of sodium chlorate in the field
requires that it be applied in conjunction with a fire retardant to
minimize fire incidents. It is unclear how the fire retardant could
influence the persistence in the field.  Even though the persistence of
chlorate in the field is uncertain, a terrestrial field dissipation data
from a study conducted as per guideline 835.6100 may not provide
adequate data because of the complexity of the chlorine oxyanion system
and analytical chemistry methodology.  Given that chloride is the end
chemical species of chlorate, it poses the question of increased
chloride from year-after-year usage (i.e., salinization), and leaching
of chloride to ground water, particularly in areas where chloride is not
a significant, natural component in soil and/or ground water.
Therefore, the Agency recommends a retrospective monitoring study (soil;
ground water) aimed to address the effect of prolong use of sodium
chlorate on cotton.  The study must be conducted upon agreement of a
protocol, but monitoring sites in coastal areas should not be included.

eligibility has been made.  The registrant must review previous data
submissions to ensure that they meet current EPA acceptance criteria and
if not, commit to conduct new studies.  If a registrant believes that
previously submitted data meet current testing standards, then the study
MRID numbers should be cited according to the instructions in the
Requirement Status and Registrants Response Form provided for each
product.  The Agency intends to issue a separate product-specific data
call-in (PDCI) outlining specific data requirements.

	To be eligible for reregistration, labeling changes are necessary to
implement measures outlined in Section IV above.  Specific language to
incorporate these changes is provided in Table 28.  Generally,
conditions for the distribution and sale of products bearing old
labels/labeling will be established when the label changes are approved.
 However, specific existing stocks time frames will be established
case-by-case, depending on the number of products involved, the number
of label changes, and other factors.

C.	Labeling Changes Summary Table

For sodium chlorate to be eligible for reregistration, all sodium
chlorate labels must be amended to incorporate the risk mitigation
measures outlined in Section IV.  Table 28 describes how language on the
labels should be amended.

Existing Stocks

Registrants may generally distribute and sell products bearing old
labels/labeling for 18 months after the date of approval of revised

1.	CONTENTS OF BIBLIOGRAPHY.  This bibliography contains citations of
all studies considered relevant by EPA in arriving at the positions and
conclusions stated elsewhere in the Reregistration Eligibility Document.
 Primary sources for studies in this bibliography have been the body of
data submitted to EPA and its predecessor agencies in support of past
regulatory decisions.  Selections from other sources including the
published literature, in those instances where they have been
considered, are included.

2.	UNITS OF ENTRY.  The unit of entry in this bibliography is called a
"study".  In the case of published materials, this corresponds closely
to an article.  In the case of unpublished materials submitted to the
Agency, the Agency has sought to identify documents at a level parallel
to the published article from within the typically larger volumes in
which they were submitted.  The resulting "studies" generally have a
distinct title (or at least a single subject), can stand alone for
purposes of review and can be described with a conventional
bibliographic citation.  The Agency has also attempted to unite basic
documents and commentaries upon them, treating them as a single study.

3.	IDENTIFICATION OF ENTRIES.  The entries in this bibliography are
sorted numerically by Master Record Identifier, or "MRID number".  This
number is unique to the citation, and should be used whenever a specific
reference is required.  It is not related to the six-digit "Accession
Number" which has been used to identify volumes of submitted studies
(see paragraph 4(d)(4) below for further explanation).  In a few cases,
entries added to the bibliography late in the review may be preceded by
a nine character temporary identifier.  These entries are listed after
all MRID entries.  This temporary identifying number is also to be used
whenever specific reference is needed.

4.	FORM OF ENTRY.  In addition to the Master Record Identifier (MRID),
each entry consists of a citation containing standard elements followed,
in the case of material submitted to EPA, by a description of the
earliest known submission.  Bibliographic conventions used reflect the
standard of the American National Standards Institute (ANSI), expanded
to provide for certain special needs.

a	Author.  Whenever the author could confidently be identified, the
Agency has chosen to show a personal author.  When no individual was
identified, the Agency has shown an identifiable laboratory or testing
facility as the author.  When no author or laboratory could be
identified, the Agency has shown the first submitter as the author.

b.	Document date.  The date of the study is taken directly from the
document.  When the date is followed by a question mark, the
bibliographer has deduced the date from the evidence contained in the
document.  When the date appears as (19??), the Agency was unable to
determine or estimate the date of the document.

c.	Title.  In some cases, it has been necessary for the Agency
bibliographers to create or enhance a document title.  Any such
editorial insertions are contained between square brackets.

d.	Trailing parentheses.  For studies submitted to the Agency in the
past, the trailing parentheses include (in addition to any
self-explanatory text) the following elements describing the earliest
known submission:

(1)	Submission date.  The date of the earliest known submission appears
immediately following the word "received."

(2)	Administrative number.  The next element immediately following the
word "under" is the registration number, experimental use permit number,
petition number, or other administrative number associated with the
earliest known submission.

(3)	Submitter.  The third element is the submitter.  When authorship is
defaulted to the submitter, this element is omitted.

(4)	Volume Identification (Accession Numbers).  The final element in the
trailing parentheses identifies the EPA accession number of the volume
in which the original submission of the study appears.  The six-digit
accession number follows the symbol "CDL," which stands for "Company
Data Library."  This accession number is in turn followed by an
alphabetic suffix which shows the relative position of the study within
the volume.

submitted for the chemical are properly coded and assigned to your
company, please include a list of all synonyms, common and trade names,
company experimental codes, and other names which identify the chemical
(including "blind" codes used when a sample was submitted for testing by
commercial or academic facilities).  Please provide a CAS number if one
has been assigned.

 Unless they chemisorb to soil or sediment particulates.  Chemisorption
of chlorate is unlikely.

The term “redox chemistry” is used as an overall term for oxidation
and reduction reactions.  Other terms that are frequently used for
oxidizers are “oxidants,” “oxidizing agents.”  Reductants are
frequently referred to as “reducing agents.”  All redox reactions
require an oxidant and a reductant.  Reductants are electron donors,
while oxidants are electron acceptors.
