                       I .  INTRODUCTION

     EPA has established the Registration Standards program
in order to provide an orderly mechanism by which pesticide
products containing the same active ingredient can be reviewed
and standards set for compliance with FIFRA.  The standards
are applicable to reregistration and future applications  for
registration of products containing the same active ingredient.
Each registrant of a product containing an active ingredient
subject to this Standard who wishes to continue to sell or
distribute that product must bring his product and labeling
into compliance with FIFRA, as instructed by this Standard.

     The Registration Standards program involves a thorough
review of the scientific data base underlying a pesticide's
registration.  The purpose of the Agency's review is to
reassess the potential hazards arising from the currently
registered uses of the pesticide; to determine the need for
additional data on health and environmental effects; and  to
determine whether the pesticide meets the "no unreasonable
adverse effects" criteria of FIFRA.  In its review EPA identifies:

     1.  Studies that are acceptable to support the data
requirements for the currently registered uses of the
pesticide.

     2.  Additional studies necessary to support continued
registration.  The additional studies may not have been
required when the product was initially registered or may be
needed to replace studies that are now considered inadequate.

     3.  Labeling revisions needed to ensure that the product
is not misbranded and that the labeling is adequate to protect
man and the environment.

     The detailed scientific review, which is not contained
in this document, but is available upon request-'-, focuses on
the pesticide active ingredient.   The scientific review
primarily discusses the Agency's evaluation of and conclusions
from available data ,in its files pertaining to the pesticide
active ingredient.  However, during the review of these data
the Agency is also looking for potential hazards that may be
associated with the end use products that contain the active
ingredient.  The Agency will apply the provisions of this
Registration Standard to end use products if necessary to
protect man and the environment.
•'-The scientific reviews may be obtained from the Information
 Services Section,  Program Management and Support Divi.c3ion
 (TS-757C),  EPA, 401 M St., SW, Washington, D.C.  20460.

-------
     EPA's reassessment results in the development of a
regulatory position, contained in this Registration Standard,
on the pesticide and each of its registered uses.  See
Section IV - Regulatory Position and Rationale.  Based on its
regulatory position, the Agency may prescribe a variety of
steps to be taken by registrants to maintain their registrations
in compliance with. FIFRA.  These steps may include:

     1.  Submission of data in support of product registration;

     2.  Modification of product labels;

     3.  Modifications to the manufacturing process of the
pesticide to reduce the levels of impurities or contaminants;

     4.  Restriction of the use of the pesticide to certified
applicators or other specially trained individuals;

     5.  Modification of uses or formulation types; or

     6.  Specification of packaging limitations.

     Failure to comply with these requirements may result in
the issuance of a Notice of Intent to Cancel or a Notice of
Intent to Suspend (in the case of failure to submit data).

     In addition, in cases in which hazards to man or the
environment are identified, the Agency may initiate a special
review of the pesticide in accordance with 40 CFR Part 154«
to examine in depth the risks and benefits of use of the
pesticide.  If the Agency determines that the risks of the
pesticide's use outweigh the benefits of use, the Agency
may propose additional regulatory actions, such as cancellation
of uses of the pesticide which have been determined to cause
unreasonable adverse effects on the environment.

     EPA has authority under the Data Call-in (DCI) provisions
of FIFRA sec. 3(c)(2)(B) to require that registrants submit
data to answer our questions regarding the chemical, toxicological,
and environmental characteristics and fate of a pesticide.
This Registration Standard lists the data EPA believes are
necessary to resolve our concerns about this pesticide.
These data are listed in the Tables A, B, and C in Appendix I.
Failure to comply with the DCI requirements enumerated in
this Registration Standard may result in issuance by EPA of a
Notice of Intent to Suspend the affected product"registrations.

     Registrants are reminded that FIFRA sec. 6(a)(2) requires
them to submit factual information concerning possible unreason-
able adverse effects of a pesticide at any time that they
become aware of such information.  Registrants should notify

-------
the Agency of any information, including interim or preliminary
results of studies, if those results suggest possible adverse
effects on man or the environment.  This requirement continues
as long as the products are registered by the Agency.

                   III.  AGENCY ASSESSMENT

                         A.  Summary

The Agency has reviewed all of the data submitted to support
the registration of tebuthiuron.  Based on the review of
these data, the Agency has reached the following conclusions:

1. Tebuthiuron is only slightly acutely toxic by inhalation
   in rats and is in toxicity category III..

2. A rat raultigeneration study showed no adverse reproductive
   effects.
3. Tebuthiuron did not cause DNA damage in bacteria and was
   only slightly mutagenic in a mouse lymphoma assay.

4. The Agency is concerned about the potential for ground
   water contamination by tebuthiuron.  The Agency has
   determined that additional data are needed to fully
   characterize the potential for tebuthiuron to enter
   ground water.

5. The use of tebuthiuron on rangeland and pastureland
   will pose a hazard to endangered species.


6. As a result of this review, the agency has identified
   missing data necessary to evaluate the environmental and
   human risks associated with the use of tebuthiuron.
   These data must be developed in order to maintain registra-
   tion of products or to register new products containing tebu-
   thiuron.  A summary of these data gaps appear in figure 1.
   Please note that this is only a summary and complete details
   can. be obtained by referring to the tables in Appendix I.

          B.  Preliminary Risk Assessment


1. Acute Toxicology

There are no valid studies available to assess the potential
acute oral and acute dermal toxicity of tebuthiuron. Studies
are required.  Sufficient data are available to assess the
acute inhalation toxicity of technical tebuthiuron.  The
4-hour LCjQ in rats is greater than 3.696 mg/L. (Toxicity
Category III).

There are no valid studies available to assess the primary dermal,
and dermal sensitization potential of technical tebuthiuron;
studies are required.

2. Chronic Toxicity

In a1 study of beagle dogs, 4 animals per sex per dose level
were given technical tebuthiuron by capsule for one year at
levels of 0 (Control), 12.5, 25.0, or 50.0 milligram  per
kilogram of body weight.  The effects produced included
increased liver to body weight ratios in high dose males and
females; increased kidney to body weight ratios in high dose
females, and increased thyroid ratios in high dose males.
There were no adverse histopathological findings for these
organs, however, alanine transaminase and alkaline phosphatase
values were significantly increased in the high dose males,
as was alanine transaminase in the high dose females.  This
indicates a significant hepatotoxic effect at this level in
both sexes.  Increased thrombocyte counts in the high dose
males throughout the study appear to be an isolated finding.
The NOEL based on these effects is 25 mg/kg bwt/day.


3. Oncogenicity

No acceptable oncogenicity studies are available.  Studies
in two species are required.

Tebuthiuron is one of a class of substituted dimethylurea
compounds.  Other such compounds include monuron and diuron.
Monuron has produced increased incidences of renal tubular
adenomas and carcinomas in male rats; diuron has produced
increased incidences of bladder carcinomas in male and female
mice.  Linuron, a substituted monomethylurea compound,
has induced testicular adenomas and interstitial-;cell tumors
in male mice.  These findings strongly suggest that urogenital
tissues are sensitive to subtituted raethylurea materials.
However, further evaluation of tebuthiuron is not possible
until the required oncogenicity studies are available.
                                 8

-------
4. Mutagenicity

  An Ames assay was performed using bacterial strains of Si.
  Typhimurium LT-2 with and without activation.
  Doses of technical tebuthiuron used were 5 to 5000 ug/plate.
  No tests showed evidence of induction of point mutation in 8
  testor strains of j>. Typhimurium.  Technical tebuthiuron was
  not mutagenic either with or without metabolic activation.

  Mouse lymphoma assay for the induction of forward mutations
  using the Tk+/- cell line was sensitive to direct acting and
  activation-dependant mutagens.   Technical tebuthiuron was
  slightly mutagenic without metabolic activation.  Mutation
  indices of 2.0, 2.0 and 2.7 were detected in technical
  tebuthiuron treated cultures at concentrations of 200, 400,
  and 500 ug/ml respectively.  Technical tebuthiuron was not
  mutagenic in activated assays.

5. Teratology

  A teratology study was submitted but was found to be inade-
  quate to support registration of tebuthiuron.  Gravid Harlan
  rats, 25 per group, were offered diets containing 0 (Control),
  600, 1200, or 1800 ppra technical tebuthiuron on days 6
  to 15 of gestation.  No detailed analytical data, such as
  individual dam body weights or individual litter data were
  supplied.  In adddition, the test material was offered in the
  diet rather than being given by gavage as recommended.
  Teratology studies in two mammalian species are required.

-------
6. Reproduction

   Sufficient data are available to satisfy the requirement for
   a multigeneration reproduction study.  Harlan rats,  25/sex/
   dose, were offered diets containing 0  (Control),  100,  200,
   or 400 ppm 0(Control)-,  5, 10, or 20 mg/kg bwt/day)  technical
   tebuthiuron through 2 generations of offspring.  No  adverse
   effects were reported except that F1 females, in the pre-raating
   phase, showed a lower rate of body weight gain in the 200 and
   400 ppm groups. No adverse effects were reported on reproductive
   performance at any level. The NOEL for reproductive effects
   is > 400ppm (20 mg/kg bwt/day). The NOEL for systemic effects
   is 100 ppm (5.0 mg/kg bwt/day).

7. Subchronic Toxicity

   Sufficent data are available to satisfy the requirment
   for subchronic dermal toxicity testing. New Zealand White
   rabbits, 10/sex/dose, were exposed dermally to 0 (control)
   or 1000 mg/kg of dry-form technical tebuthiuron applied to
   10 percent of the total body surface area for 21  days, 6
   hours per day. No signs of dermal toxicity or deaths were
   reported. Two of the ten treated animals showed slight
   erythema, which cleared by day 7. No systemic effects that
   could be attributed to dermal exposure were reported.

8. Metabolism

   Radiolabeled technical tebuthiuron was administered in the
   diet at 100 and 200 ppm (5 and 10 mg/kg bwt/day, respectively),
   to lactating rats immediately postpartum. The period of
   diet administration was 48 hours. The  dams were milked and
   the amount of activity in the milk was determined.  The mean
   14c levels in rats' milk were 2.7 ppm  and 6.2 ppm for the
   100 and 200 ppm rats, respectively. Technical tebuthiuron
   and/or its metabolites appear in milk  of lactating  rats.
   General metabolism studies are not available for technical
   tebuthiuron. These studies are required.
                                 10

-------
                C.  Other Science Findings

1. Enviornmental Characteristics


                         Degradation

Tebuthiuron did not undergo significant degradation at pH 5,
7 and 9 at 25°C in 64 days and is considered stable in sterile
water.

Preliminary data indicate that tebuthiuron is also quite stable
under aerobic and anaerobic soil conditions.  Tebuthiuron only
degraded from 8 ppm to 5.7 ppm after 273 days (half life > 1
year); when incubated in loam soil at 25°C and was reported to
degrade in an identical soil under anaerobic conditions with a
halflife of >48 weeks. Similarly, irradiation with an artifical
light that did not quite simulate sunlight resulted in only
42% decomposition after 15 days.

Tebuthiuron appears stable to biological and chemical degrada-
tion under environmental conditions and can be considered
persistent.

     ;    : •               Leaching

Preliminary data indicate that tebuthiuron is mobile to very
mobile in loam, loamy sand, and lakeland sand soils and slightly
mobile in silty loam soil. Values of lower than 2 were re-
ported for clay, sandy loam and sand soils.  About 40% of residues
of a 30 days sandy loam aged tebuthiuron were found in the
leachate.

Based on the above information, tebuthiuron has the
potential to leach through a variety of soils and contaminate
groundwater. Tebuthiuron was flagged as a groundwater
contaminant through the GWDCI (Ground Water Data Call In)
screen and has been found in shallow groundwater in Texas.

Tebuthiuron will be furthur analyzed in the Agency's
National Pesticides in Well Water Survey.

Existing data which were submitted in response to a Ground
Water Data Call-in have been found to be inadequate to full-
fill Agency guideline requirements.  Therefore, additional
data are necessary to fully characterize tebuthiuron1s ability
to contaminate ground water.
                                 11

-------
2. Ecological Characteristics


Through dietary administration, tebuthiuron is no more than
slightly toxic to birds; however, avian dietary data are in-
complete.  Avian reproductive studies show that tebuthiuron
has no effect on avian reproduction at dietary levels up to
100 ppm.

Tebuthiuron is practically non-toxic (acutely) to fish and
aquatic invertebrates.  A fish early life-stage study gives a
MATC (Maximum Allowable Toxic Concentration) between 9.3
and 18 mg/1 based on impaired growth.  Aquatic invertebrates show
significant reduction of growth and fecundity at 44 mg/1.  The
MATC'for aquatic invertebrates is between 21.8 and 44.2 ppm.
    \
Tebuthiuron was practially non-toxic to oyster embryos and
slightly toxic to pink shrimp.  No data are included on non-
target insects.  As some of the uses of tebuthiuron involve
foliar application to non-crop areas, honey bee exposure is
possible and toxicity to honey bees must be assessed.  Therefore,
a honeybee acute contact LD5Q is required.

3. Residue Monitoring

In 1972 tebuthiuron was conditionally registered for control
of brush in rangeland in Texas and Oklahoma.  As a requirement
of the registration the registrant was requested to perform
a field monitoring study which would better define this
chemical's actions in aquatic and terrestrial environments.
Instead of a single monitoring study, several studies (EPA
Accession No. 246373) were submitted by the registrant to
fulfill the conditional requirement.  While each study had
several deficiencies and none of them would satisfy individ-
ually the data requirement, the series of studies were consider-
ed sufficient to satisfy the monitoring condition of the 1979
registration.  In 1982, in response to a request for the addi-
tion of 17 states to the tebuthiuron registration, the Agency
requested that the registrant continue (into a second year) the
monitoring of water and hydrosoil at four study sites.  The
Agency is now requiring that these data be submitted to
support the registration of tebuthiuron.
                                12

-------
Because of tebuthiuron1s extreme persistence, these monitoring
data are still necessary to determine the long-term availability
of the chemical for runoff into aquatic systems and the likeli-
hood of long-term buildup of tebuthiuron in the soil.  Monitor-
ing data are being required through this Registration Standard.
If information from past monitoring is not available or is
determined to be unsatisfactory, a new monitoring study will
be required.


4. Endangered Species

The use of tebuthiuron on rangeland, pastureland, and general
nondrop areas should not pose a hazard to endangered or
threatened terrestrial or aquatic animal species.  However,
the use of tebuthiuron on rangeland and pastureland will pose a
hazard to endangered and threatened plant species.  Products
containing tebuthiuron with range and pasture uses which are
released for shipment after February 1, 1988 must bear Endangered
Species Labeling.

Endangered Species Labeling for non-crop, wide area, and general
indoor/outdoor treatments is deferred until completion of the
analysis by OES and the Agency of the Non-crop use Cluster.
                               13

-------
5. Product Chemistry

The Agency has evaluated the available data, which
identify the ingredients, materials, and manufacturing process
and discuss the physical and chemical properties of tebuthiuron,
In particular, the Agency has noted the possibility of the
formation of nitrosamines.  Analysis to identify and quantify
nitrosamines is being required along with additional product
chemistry data requirements identified in the data tables.

                D. Tolerance Reassessment

Tolerances have been established for residues of
tebuthiuron in a variety of raw agricultural commodities, in
meat;, fat, and meat byproducts (40 CFR 180.390).  EPA has
evaluated the residue and toxicology data supporting tolerances
and has determined:

  0  Whether the current tolerances and food additive
     regulations are sufficient to cover the actual
     residues resulting from use (including uses re-
     gistered under FIFRA section 24(c) and intrastate
     uses-).

  0  Whether group tolerances can be established in
     accordance with 40 CFR 180.34(f).

  0  Whether in the absence of tolerances, restrictions
     on use, grazing, or feeding of treated commodities
     are necessary.

  0  Whether the tolerances are expressed accurately and
     in current terminology.

The regulatory results of the Agency's review are set out in
Section IV.A, Regulatory Positions and Rationales.
                                 14

1.  Residue Data

The residue data reviewed in support of tebuthiuron
tolerances include the following:

a..  Data on the nature of the residues in both
plants and animals, including identification of major metabo-
lites and degradates of tebuthiuron.  The metabolism is not
completely understood.  The available plant metabolism data
from the sugarcane study are not adequate because 76 percent of
the total 1^c-activity was nonextractable and was not character-
ized.  The metabolites 104(OH), 106, 107, and 108 are not re-
ported to be quantified by the residue analytical method for
grasses.

b.  kadiolabeled studies on the uptake, translocation,
and metabolism of tebuthiuron in grass.  These studies do not
provide sufficient information regarding residues in plants.

c.  Radiolabeled studies on the metabolism of tebuthiuron in
ruminants, including milk.  The ruminant studies are not
adequate to permit conclusions regarding the adequacy of exist-
ing or pending tolerances.  Animals must be dosed for at least 3
days with ringlabeled [14C] tebuthiuron at a concentration that
will result in sufficient residues for characterization in the
tissues and milk. This study must also elucidate the identities
and quantities of all metabolities in milk, liver, kidney, muscle,
and fat.

d.  Storage stability data are needed which demonstrating
residues of tebuthiuron are stable in or on plant and animal
commodities.  Sample history information is also needed.

e.  Data on the magnitude and levels of residues of
tebuthiuron in individual raw agricultural commodities, animal
products, and processed food and feed items are needed.

2.  Toxicology Data

The toxicology data considered in support of the
tolerances include a 1-year dog feeding study,90-day rat feed-
ing study and a raultigeneration rat reproduction study.  The
one year dog study showed a NOEL of 25.0 mg/kg bwt/day based on
increased liver, kidney, and thyroid gland ratios-.'and increased
alkaline phosphatase, alanine transaminase, and thrombocyte
count values in high-dose males and females.  The 90-day rat
feeding study, had a NOEL of 50 mg/kg bwt/day based on increased
liver and kidney in body weight ratio in males and females in
the high-dose group.

           3.  Tolerances Issued

Tolerance are established for residues of the herbicide
tebuthiuron and its metabolites containing the dimethyl ethyl
thiadiazole moiety in or on the following raw
agricultural commodities (40 CFR 180.390):

IV.       REGULATORY POSITION AND RATIONALE

A.  Regulatory Positions and Rationales

Based on a review and evaluation of all available
data and other relevant information on the herbicide tebuthiu-
ron, the Agency has reached the determinations listed below.

1. The Agency will not place tebuthiuron into
special review at this time.

Rationale: Based on available data tebuthiuron does not
exceed the risk criteria for adverse effects in 40 CFR
154.7. Tebuthiuron is not acutely toxic by inhalation in rats
and is Category III. Subchronic feeding studies in rats and
chron'ic feeding studies in dogs indicate only mild effects on
the liver, kidneys, gonads, spleen, and prostate and thyroid
glands.


2. The Agency will not require reentry protection data to be
submitted or impose an interim reentry interval for tebuthiuron
products- at this time.

Rationale;  Tebuthiuron does not meet the criteria in Section
158.140 reentry data submitted:  acute toxicity appears to be
low (toxicity Category III by the inhalation route), and the
Agency has insufficient evidence of chronic effects and no
evidence of poisoning incidents associated with its use.
Little reentry exposure would be expected from pre-emergent
and early postemergent use of tebuthiuron on non-crop and
rangeland sites.

3.  The Agency's data on tebuthiuron in meat and milk
residues are not being assessed at the present time.  New data
defining the nature of the residue in animals are required.

Rationale;  The Agency has determined a secondary
residue of tebuthiuron in meat and milk occurs through the
ingestion by livestock of treated grass hay, forage, and range
land.  However, data defining the nature of the residue in
animals are unavailable.  Therefore, the adequacies of avail-
able data on these residues in meat and milk cannot be assessed,

4. The Agency is requiring endangered  species lab.eling on
tebuthiuron End-Use-Products registered for use oti range
and/or pastureland in accordance with PR Notice 87-5 (issued
May 1, 1987).
                                 17

-------
Rationale;  Tebuthiuron was reviewed for endangered species
implications in consultation with the Office of Endangered
Species, U.S. Fish and Wildlife Service.  This review resulted
in a determination that use of tebuthiuron on range and/or
pastureland may pose jeopardy to endangered and threatened
plant species.  In order to protect these species from harm
endangered species labeling is required. The Labeling is
indentified in Section 4.D of this document.

5. The Agency will not require groundwater advisory state-
ments on tebuthiuron products at this time, but will further
evaluate the potential of tebuthiuron to contaminate ground
water after it has received and evaluated additional required
environmental fate data.

Rationale:  Base on column leaching studies, tebuthiuron
is mobile to very mobile in loam, sandy loam, and sand soils,
which indicates that a potential for leaching into ground
water exists.  This potential, however, can not be fully
characterized until the Leaching and Adsorption/Desorption
studies are submitted.
6. Additional residue monitoring data for water and hydrosoil
are required.

Rationale: Because of the extreme persistence of tebuthiuron,
monitoring is essential  in order to better determine the
long-term availability of tebuthiuron for runoff into aquatic
systems and the likelihood of long-term buildup of tebuthiuron
in the hydrosoil.

7. The present precautionary statements for persons who handle
tebuthiuron products are sufficient for the labels of manufactur-
ing-use and end-use products.

Rationale;  Available data indicate that tebuthiuron appears
to have low acute toxicity (Category III).  Therefore, the
labeling of these products which contains statements that
caution persons applying or handling this compound, give
first aid instructions, and require the use of precautionary
measures to ensure safe handling of pesticide product, are
adequate.
                              18

-------
8.  The Agency is requiring residue data for rangeland,
forage grasses, and grass hay.

Rationale;  The data available are inadequate to support the
group tolerance in animal feedstuffs because the studies sub-
mitted were for unidentified grass and forage.

9.  The Agency has determined that, based on the available
data, it will not establish further food tolerances pending
receipt of the required chronic and oncogenicity studies.

Rationale;  These studies must specifically address the
question of potential oncogenic response in the urogenital
system and the liver, with careful attention given to the
histopathology of the kidney and other surrounding organs
due'to tebuthiuron's similarity to Linuron, Diuron and Monuron,
    \

10. The Agency has identified certain data that will
receive priority review when submitted to the Agency.

Rationale;  Certain data are essential to the Agency's
assessment of this pesticide and its uses and/or may trigger
the need for further studies which should be initiated as
soon as possible.  The following studies have been identified
to receive priority review as soon as they are received by
the Agency.

11. While data gaps are being filled, currently
registered manufacturing-use products and end-use products
containing tebuthiuron must be formulated, and used, subject
to the terms and conditions specified in this Standard.
Registrants must provide or agree to develop additional
data as specified in the data appendices in order to maintain
existing registrations.

Rationale:  Under FIFRA, the Agency may choose not to
cancel or withhold registration if data are missing or are
inadequate.  See FIFRA section 3(c)(2)(B) and 3(c)(7).

Issuance of this Standard provides a mechanism for
identifying data needs.  These data will be reviewed and
evaluated, after which the Agency will determine if additional
regulatory changes are necessary.
                                 20

-------
 B.   CRITERIA  FOR REGISTRATION

    To  be  registered or reregistered under this Standard,
 products  must contain Tebuthiuron as the sole active
 ingredient, bear required labeling, and conform to the product
 composition,  acute toxicity limits, and use pattern requirements
 listed  in  this section.

 C.   ACCEPTABLE RANGES AND LIMITS

     1.  Product Composition Standard

     To be registered or reregistered under this Standard,
 manufacturing-use products (MPs) must contain  Tebuthiuron
 as,the sole active ingredient.  Each MP formulation proposed
 f6r registration must be fully described with an appropriate
 certification of limits, stating maximum and minimum amounts
 of  the active ingredient and inert ingredients which are
 present in products/ as well as impurities found at greater
 than O.lt.

     2.. Acute Toxicity Limits

     The Agency will consider registration of technical grade
 and manufacturing-use products containing Tebuthiuron
 provided that the product labeling bears appropriate precaution-
 ary statements for the acute toxicity category  in which each
 product is placed.
                                                          e
     3.  Use Patterns

     To be registered under this Standard, manufacturing-use
products may be labeled for formulation  into end-use  products
 registered  for the uses listed in Appendix B,  EPA  Index  to
Pesticide Chemicals — Tebuthiuron.  The EPA Index  to
Pesticide Chemicals lists all registered uses,  as well as
approved maxinun application rates and frequencies.
                                     21

-------
D. REQUIRED LABELING

Products subject to the requirements of this Registration
Standard may not be released for shipment after August 1, 1988
unless the product bears amended labeling which complies
with the requirements of this Standard.  [EXCEPTION:  Endanger-
ed Species labeling must be on products released for shipment
after February 1, 1988 and on all products after February 1,
1989 as specified in. Pesticide Registration (PR) Notice 87-5
(issued May 1, 1987).]  After reviewing data to be submitted
under this Standard, the Agency may impose additional labeling
requirements.

Products subject to the requirements of this Registration
Standard may not be distributed, sold, offered for sale, held
for sale, shipped, delivered for shipment, or received and
(having been so received) delivered or offered to be delivered
by any person after August 1, 1989 unless the product bears
amended labeling which complies with the requirements of
this standard.

            V.  PRODUCTS SUBJECT TO THIS STANDARD

      All  products containing one or more of the pesticides
 identified  in Section II.A. are subject to certain requirements
 for data  submission or changes in composition,  labeling or
 packaging of the product.  The applicable requirements  depend
 on  whether  the product is a manufacturing or end use product
 and whether the pesticide is the sole active ingredient or
 one of  multiple active ingredients.

     Products are subject to this Registration Standard  as
 follows:

 A.   Manufacturing; use products containing this pesticide as
 the sole  active Ingredient are subject to:
  i
      1.   The restrictions (if any) upon use, composition, or
      packaging listed in Section IV, if they pertain to the
      manufacturing use product.

      2.   The data requirements listed in Tables A and B2.

      3.   The labeling requirements specified for manufacturing
      use  products in Section IV.

      4.   Administrative requirements (application forms, Confiden-
      tial Statement of Formula/ data compensation provisions)
      associated with reregistration.
2 Data requirements are listed  in  the  three Tables  in
Appendix I of this Registration Standard.  The Guide to
Tables in that Appendix explains how to  read  the Tables.

  Table A lists generic data  requirements  applicable to  all
products containing the pesticide  subject  to  this Registra-
tion Standard.  Table 8 lists product-specific data applicable
to manufacturing use products.  The data in Tables  A and B
need not be submitted by  a  producer who  is eligible for  the
formulator's exemption for  that active ingredient.

  Table C lists product-specific data  applicable  to end  use
products.  The Agency has decided  that*  in most  cases, it
will not require the submission of product-specific data for
end use products at this  time.  Therefore most Registration
Standards do not contain  a  Table C.
                                  26

-------
B.  Manufacturing use products containing this pesticide
as one o£ multiple active ingredients are subject to:

     The data requirements listed in Table A.

C.  End use products containing this pesticide as the
sole active ingredient are subject to:

     1.  The restrictions (if any) upon use, composition, or
     packaging listed in Section IV if they pertain to the
     end use product.

     2.  If not eligible for the formulator's exemption, the
     data requirements listed in Table A.

    , 3.  The labeling requirements specified for end use
    \ products in Section IV.

D.  End use products containing this pesticide as one of
multiple active ingredients are subject to:

     a.  If not eligible for the formulator's exemption,
     the data requirements listed in Table A.
^ If you purchase from another producer and use as the
source of your active ingredient only EPA-registered products,
you are eligible for the formulator's exemption for generic
data concerning that active ingredient (Table A) and product-
specific data for the registered manufacturing use product
you purchase (Table B1.

     Two circumstances nullify this exemption:

     1)  If you change sources of active ingredient to an
unregistered product, formulate your own active ingredient,
or acquire your active ingredient from a firm with ownership
in common with yours, you individually lose the exemption
and become subject to the data requirements in Table A.

     2)  If no producer subject to the generic data requirements
in Table A agrees to submit the required data, all end use
producers lose the exemption,  and become subject to those
data requirements.,-
                                  27

-------
       VI.  REQUIREMENT FOR SUBMISSION OF GENERIC  DATA

     This portion of the Registration Standard  is  a  notice
 issued under the authority of FIFRA sec. 3(c)(2)(B).  It
 refers to the data listed in Table A, which are  required  to
 be  submitted by registrants to maintain  in effect  the regis-
 tration of products containing this active ingredient.4

 A.  What are generic data?

     Generic data pertain to the properties or effects of a
 particular active ingredient.  Such data are  relevant to  an
 evaluation of all products containing that active  ingredient
 regardless of whether the product contains other ingredients
 (uniless the product bears labeling that would make the data
 requirement inapplicable).
   (
     Generic data may also be data on a  "typical formulation"
 of  a product.  "Typical formulation" testing  is  often required
 for ecological effects studies and applies to all products
 having that formulation type.  These are classed as  generic
 data, and are contained in Table A.

 B.  Who* must submit generic data?

     All current registrants are responsible  for submitting
 generic data in response to a data request under FIFRA sec.
 3(c)(2)(B) (DCI Notice).  EPA has decided, however,  not to
 require a registrant who qualifies for the formulator*s
 exemption (FIFRA sec. 3(c)(2)(D) and S 152.85) to submit  '
 generic data in response to a OCI notice if the  registrant
 who supplies the active ingredient in his product  is complying
 with the data request.

     If you are granted a generic data exemption, you rely on
 the efforts of other persons to provide  the Agency with the
 required data.  If the registrants who have committed to
 generate and submit the required data fail to take appropriate
 steps to meet the requirements or are no longer  in compliance
 with this data requirements notice, the Agency will  consider
 that both they and you are not in compliance  and will normally
 initiate proceedings to suspend the registrations of both
 your product(s) and their product(s) unless you  commit to submit
 and submit the required data in the specified timeframe.  In
 such cases, the Agency generally will not grant  a time extension
 for submitting the data.
-  Registrations granted after issuance of this Standard will
be conditioned upon submission or citation of the data listed
in this Registration Standard.
                                  28

-------
     If you are not now eligible for a formulator's exemption,
you may qualify for one if you change your source of supply
to a registered source that does not share ownership in
common with your firm.  If you choose to change sources of
supply, the Confidential Statement of Formula must identify
the new source(s) and you must submit a Formulator's Exemption
Statement form.

     If you apply for a new registration for products containing
this active ingredient after the issuance of this Registration
Standard, you will be required to submit or cite generic
data relevant to the uses of your product if, at the time
the application is submitted, the data have been submitted
to the Agency by current registrants.  If the required data
have not yet been submitted, any new registration will be
conditioned upon the new registrant's submission or citation
of;the required data not later than the date upon which
current registrants of similar products are required to provide
such data.  See FIFRA sec. 3(c)(7)(A).  If you thereafter fail
to comply with the condition of that registration to provide
data, the registration may be cancelled (FIFRA sec. 6(e)).

C.  What generic data must be submitted?
      »-
     You may determine which generic data you must submit by
consulting Table A.  That table lists the generic data needed
to evaluate current uses of all products containing this
active ingredient, the uses for which such data are required,
and the dates by which the data must be submitted to the
Agency.

D.  How to comply with PCI requirements.

     Within 90 days of your receipt of this Registration
Standard, you must submit to EPA a completed copy of the form
entitled "FIFRA Section 3(c)(2)(B) Summary Sheet" (EPA Form
8580-1, enclosed) for each of your products.  On that form
you must state which of the following six methods you will
use to comply with the DCI requirements:
                   •
     1.  You will submit the data yourself.

     2.  You have entered into an agreement with one or more
registrants to jointly develop (or share in the cost of"
developing) the data, but will not be submitting the data
yourself.  If you use this method, you must state who will
submit the data on which you will rely.  You must also provide
EPA with documentary evidence that an agreement has been
formed which allows you to rely upon the data to be submitted.
Such evidence may be:  (1) your.letter offering to join in
an agreement and the other registrant's acceptance of your
offer, (2) a written statement by the parties that an agreement
exists, or. (3)^a written statement by the person who will be
submitting the'data.that you may rely upon its submission.


                          29

-------
The Agency will also require adequate assurance that the
person whom you state will provide the data is taking appropriate
steps to secure it.  The agreement to produce the data need
not specify all of the terms of the final arrangement between
the parties or a mechanism to resolve the terms.

     If you and other registrants together are generating or
submitting requested data as a task force or consortium, a
representative of the group should request a Joint Data
Submitter Number from the Registration Support and Emergency
Response Branch, Registration Division.  The request must
include the following information:

     a.  A list of the members of the consortium;
    i b.  The name and address of the designated representative
         of the consortium, with whom EPA will correspond
    1     concerning the data;
     c.  Identity of the Registration Standard containing
         the data requirement;
     d.  A list of the products affected (from all members
         of the consortium); and
     e.  Identification of the specific data that the con-
         sortium will be generating or submitting-
       *
     The Agency will assign a number to the consortium, which
should be used on all data submissions by the consortium.

     3.  You have attempted to enter into an agreement to
jointly develop data, .b_ut._no other registrant has accepted
your offer.  You request that EPA not suspend your registration
for non-compliance with the PCI.EPA has determined that,
as a general policy, it will not suspend the registration of
a product when the registrant has in good faith sought and
continues to seek to enter into a data development/cost
sharing program, but the other registrants developing the
data have refused to accept its offer.  [If your offer is
accepted, you may qualify for Option 2 above by entering
into an agreement to supply the data.]

     .In order to qualify for this method, you must:

     1.  File with EPA a completed "Certification of Attempt
to Enter into an Agreement with other Registrants for Develop-
ment of Data" (EPA Form £580-6, enclosed).

     2.  Provide us with a copy of your offer to* the other
registrant and proof of the other registrant's receipt of your
offer (such as a certified mail receipt).  Your offer must,
at a minimum, contain the following language or its equivalent:
                           30

-------
     [Your company name] offers to share in the burden of
     producing the data required pursuant to FIFRA sec.
     3(c)(2)(B) in the  [name of active ingredient] Registration
     Standard upon terms to be agreed or failing agreement
     to be bound by binding arbitration as provided by FIFRA
     section 3(c)(2)(B)(iii).

The remainder of your offer may not in any way attempt to
limit this commitment.  If the other registrant to whom your
offer is made does not accept your offer, and if the other
registrant informs us on a DCI Summary Sheet that he will
develop and submit the data required under the DCI, then you
may qualify for this option.  In order for you to avoid
suspension under this method,  you may not later withdraw or
limit your offer to share in the burden of developing the
data.

     In addition, the other registrant must fulfill its
commitment to develop and submit the data as required by this
Notice in a timely manner.  If. the other registrant fails to
develop the data or for some other reason would be subject to
suspension, your registration as well as that of the other
registrant will normally be subject to initiation of suspension
proceedings, unless you commit to submit and submit the required
data in the specified timeframe.  In such cases, the Agency
generally will not grant a time extension for submitting the data.

     4.  You request a waiver of the data requirement.  If
you believe that a data requirement does not (or should not)*
apply to your product or its uses, you must provide EPA with
a statement of the reasons why you believe this is so.  Your
statement must address the specific composition or use factors
that lead you to believe that a requirement does not apply.
Since the Agency has carefully considered the composition and
uses of pesticide products in determining that a data require-
ment applies, EPA does not anticipate that many waivers will
be granted.  A request for waiver does not extend the time-
frames for developing required data, and if your waiver
request is denied, youj: registration may be suspended if you
fail to submit the data.

     5.  You request that EPA amend your registration by deleting
the uses for which the data^ are needed.  You are not required
to submit data for uses which are no longer on your label.

     6.  You request voluntary cancellation of the registration
of your product(s) for which the data are needed.
                           3!

E.  Testing Protocols, Standards for Conducting Acceptable
    Tests, Guidance on Evaluating and Reporting Data.

    All studies required under this Notice must be conducted
in accordance with test standards outlined in the Pesticide
Assessment Guidelines, unless other protocol or standards are
approved for use by the Agency in writing.

    As noted herein, these EPA Guidelinesr which are referenced
in the Data Tables, are available from the National Technical
Information Service (NTIS), Attn: Order Desk, 5285 Port Royal
Road, Springfield, VA  22161 (tel: 703-487-4650).

    Protocols approved by the Organization for Economic
Cooperation and Development (OECD) are also acceptable if
the; OECD-recommended test standards conform to those specified
in the Pesticide Data Requirements regulation (Part 158.70).
Please note, however, that certain OECD standards (such as
test duration, selection of test species, and degradate
identification which are environmental fate requirements) are
less restrictive than those in the EPA Assessment Guidelines
listed above.  When using the OECD protocols, they should be
be modified as appropriate so that the data generated by the
study will satisfy the requirements of Part 158.  Normally,
the Agency will not extend deadlines for complying with data
requirements when the studies were not conducted in accord
with acceptable standards.  The OECD protocols are available
from OECD, 1750 Pennsylvania Avenue, N.W., Washington, D.C.
20006.
                                                         •

F.  Procedures for requesting a change in testing protocol.

     If you will generate the required data and plan to use
test procedures which deviate from EPA's Pesticide Assessment
Guidelines or the Reports of Expert Groups to the Chemicals
Group, Organization for Economic Cooperation and Development
(OECD) Chemicals Testing Programme, you must submit for EPA
approval the protocols you propose to use.

     You should submit your protocols before beginning testing,
because the Agency will not ordinarily accept as sufficient
studies using unapproved protocols.  A request for protocol
approval will not extend, the timeframe for submission of the
data, nor will extensions generally be given to conduct
studies due to submittal of inappropriate protocols.


G.  Procedures for requesting extensions of time.

     If you think that you will need more time to generate
the dat-a than is allowed by EPA's schedule, you may submit a
request for an extension of time.  Any request for a time
                          32

-------
extension which is made as an initial response to a section
3(c)(2)(B) request notice must be submitted in writing to
the Product Manager listed at the end of this section and
must be made by the 90-day deadline for response.  Once
dates have been committed to and EPA has accepted these
commitments, any subsequent requests for a time extension
must be submitted in writing to the Office of Compliance
Monitoring at the address given in Section IX. E.

     EPA will view failure to request an extension before
the data submission response deadline as a waiver of any
future claim that there was insufficient time to submit the
data.  While EPA considers your request, you must strive to
meet the deadline for submitting the data.
   i
     The extension request should state the reasons why you
believe that an extension is necessary and the steps you
have taken to meet the testing deadline.  Time extensions
normally will not be granted due to problems with laboratory
capacity or adequacy of funding, since the Agency believes
that with proper planning these can be overcome.

     A request for an extension does not extend the timeframe
for submission of the data.  If EPA denies your request for
a time extension and you do not submit the data as requested,
EPA may begin proceedings to suspend the registrations of
your products.

H.  PR Notice 86-5 and Any Other Requirements Referenced or
    Included Within this Notice.

    All data submitted in response to this Notice must comply
with EPA requirements regarding the reporting of data,
including the manner of reporting, the completeness of results,
and the adequacy of any required supporting (or raw) data,
including, but not limited to, requirements referenced or
included in this Notice or contained in PR Notice 86-5 (issued
July 29, 1986).

I.  Existing stocks provision upon suspension or cancellation.

     The Agency has determined that if a registration is
suspended for failure to Despond to a DCI request under
FIFRA sec. 3(c)(2)(B), an existing stocks provision is not
consistent with the Act.  Accordingly, the Agency does not
anticipate granting permission to sell or distribute existing
stocks of suspended product except in rare circumstances.
If you believe that your product will be suspended or cancelled
and that an existing stocks provision should be granted, you
have the burden of clearly demonstrating to EPA that granting
                            33

-------
such permission would be consistent with the Act.   The following
information must be included in any request for an existing
stocks provision:

     1.  Explanation of why an existing stocks provision is
     necessary, including a statement of the quantity of
     existing stocks and your estimate of the time required
     for their sale or distribution;  and

     2.  Demonstration that such a provision would be consis-
     tent with the provisions of FIFRA.
                              34

  .  VII.  REQUIREMENT FOR SUBMISSION OF REVISED LABELING

     FIFRA requires each product to be labeled with accurate,
complete and sufficient instructions and precautions, reflecting
the Agency's assessment of the data supporting the product
and its uses.  General labeling requirements are set out in
40 CFR 162.10 (see Appendix II - LABELING and SUMMARY).  In
addition, labeling requirements specific to products containing
this pesticide are specified in Section IV.D of this Registra-
tion Standard.  Applications submitted in response to this
notice must include draft labeling for Agency review.

     If you fail to submit revised labeling as required,
which complies with 40 CFR 162.10 and the specific instructions
in Section IV.D., EPA may seek to cancel or suspend the
^registration of your product under FIFRA sec. 6.

                           TGUIDE-1

                       GUIDE TO TABLES

     Tables A contain listings of data requirements
for the pesticides covered by this Registration Standard.

     Table A contains generic data requirements that apply to
     the pesticide in all products, including data requirements
     for which a "typical formulation" is the test substance.

     The data tables are generally organized according to the
following format:

1.  Data Requirement (Column 1).  The data requirements are
listed in the order in which they appear in 40 CFR Part 158.
T^he reference numbers accompanying each test refer to the
test protocols set out in the Pesticide Assessment Guidelines,
which are available from the National Technical Information
Service, 5285 Port Royal Road, Springfield, VA  22161.

2.  Test Substance (Column 2).  This column lists the composition
of the test substance required to be used for the test, as
follows:

    *TGAI » Technical grade of the active ingredient
     PAI =  Pure active ingredient
     PAIRA » Pure active ingredient, radio labeled
    "TEP »  Typical end use formulation
     MP =   Manufacturing use product
     EP =   End use product
                                                       •
Any other test substances, such as metabolites, will be
specifically named in Column 2 or in footnotes to the table.

3.  Use pattern (Column 3).  This column indicates the use
patterns to which the data requirement applies.  Use patterns
are the same as those given in 40 CFR Part 158.  The following
letter designations are used for the given use patterns:

     A = Terrestrial, food
     B = Terrestrial, non-food
     C = Aquatic, food
     D = Aquatic, non-food
     E * Greenhouse,  food
     F = Greenhouse,  nbn-food
     G = Forestry
     H = Domestic outdoor
     I * Indoor

Any other designations will be defined in a footnote to the table.
                           38

-------
                           TGUIDE-2

4.  Does EPA have data? (Column 4).  This column indicates one
of three answers:

     YES - EPA has data in its files that satisfy this data
     requirement.  These data may be cited by other registrants
     in accordance with data compensation requirements of
     Part 152, Subpart E.

     PARTIALLY - EPA has some data in its files, but such data
     do not fully satisfy the data requirement.  In some cases,
     the Agency may possess data on one of two required species,
     or may possess data on one test substance but not all.
     The term may also indicate that the data available to
     EPA are incomplete.  In this case, when the data are
     clarified, or additional details of the testing submitted
     by the original data submitter, the data may be determined
     to be acceptable.  If this is the case, a footnote to
     the table will usually say so.

     N(3 - EPA either possesses no data which are sufficient
     to fulfill the data requirement, or the data which EPA
     does possess are flawed scientifically in a manner that
     cannot be remedied by clarification or additional infor-
     mation.

5.  Bibliographic citation (Column 5).  If the Agency has
acceptable data in its files, this column lists the identifying
number of each study.  This normally is the Master Record
Identification (MRID) number, but may be a GS number if no
MRID number has been assigned.  Refer to the Bibliography
Appendices for a complete citation of the study.

6.  Must additional data be submitted? (Column 6).   This
column indicates whether the data must be submitted to the
Agency.  If column 3 indicates that the Agency already has
data, this column will usually indicate NO.  If column 3
indicates that the Agency has only partial data or no data,
this column will usually indicate YES.  In some cases, even
though the Agency does not have the data, EPA will not require
its submission because of the unique characteristics of the
chemical; because data on another chemical can be used to
fulfill the data requirement; or because the data requirement
has been waived or reserved.   Any such unusual situations
will be explained in a footnote to the table.

7.  Timeframe for submission (Column 7).  If column 5 requires
that data be submitted,this column indicates when the data
are to be submitted, based on the issuance date of the Regis-
tration Standard.  The timeframes are those established either
as a result of a previous Data Call-In letter, or standardized
timeframes established by PR Notice 85-5 (August 22, 1985).

8.  Footnotes (at the end of each table).  Self-explanatory.

 §158.125 Residue Chemistry Footnotes
]_/ Data must be depicting the uptake, distribution, and metabolism of thiadiazole ring-labeled [^C]  tebuthiuron in
   rangeland and conducted pasture grass following broadcast application at a rate sufficiently high  to permit
   complete 14c residue identification.
2/ Representative samples from the required metabolism studies must also be analyzed using accepted enforcement methods
   to ascertain that these methods will determine all possible metabolites of concern.
3/ A metabolism study utilizing ruminants must be submitted.  Animals must be dosed for at least 3 days with ring-
   labeled [14C] tebuthiuron at a concentration that will result in sufficient residues for characterization in the
   tissues and milk.  Studies must also elucidate the identities and quantities of all  metabolites in milk, liver,
   kidney, muscle, and fat.  Milk must be collected twice daily during the dosing period.   Animal must be sacrificed
   within 24 hours of the final dose.  Since grass is not a poultry feed item, no poultry  metabolism  study is required
   at this time.
4/ Representative samples from the above described test must also be analyzed by current enforcement  methods to
~  ascertain the validity of these methods.
5/ Residues of tebuthiuron and metabolites 104, 106, 109, and 103(OH) in or on crop samples must be subjected to
   analysis by multiresidue protocols.  Protocols for Methods I, II, III, and IV are available from the National
   Technical Information Service under Order No. PB 203734/AS.
6/ Additional methods, validation data, and residue data (for representative commodities)  may be required if the
~  metabolism studies requested in the sections entitled "Nature of the Residue in Plants" and "Nature of the
   Residue in Animals" reveal additional metabolites of toxicological concern in or on  plants or in animals.
TJ The storage intervals and conditions must be submitted for all samples used to support  all tolerances for residues
~  of tebuthiuron in or on plant and animal commodities.  These data must be accompanied by data depicting the decline
   of residues during the intervals and under the conditions specified.
8/ Residue data requested in this Standard must be accompanied by information describing the storage  conditions and
~~  intervals for all samples analyzed.  These data must be accompanied by fortification recovery data depicting the
   stability of residues of concern in appropriate sample substrates under the storage  conditions and for the time
   intervals specifiedr
9_/ Data must be submitted depicting tebuthiuron residues of concern in or on fresh grass and field-dried hay of
   bermudagrass, bluegrass, and bromegrass or fescue treated with a single application  of  a Pellet/Tablets
   formulation, by ground or air equipment, at 4 Ib/ai/A.  Fresh grass samples must be  collected every 2 weeks for the
   first 3 months following application, and monthly for the following 21 months in order  to determine the maximum
   residue level that may occur any time following application.  Hay samples must be collected up to 2 years following
   the application.  If other grasses are tested, the grass species must be identified  for each test  and the species
   must be representative for the region in which it was tested.  Tests must be conducted  in AR (3%), KS (4%), KY (6%),
   MO (11%), NY (5%), OK (4%), PA (4%),~TN (4%), TX (13%), and VA (3%), which collectively produced ca. 57% of the
   total domestic hay crop in 1982 (production figures follow in parentheses).  Tests must also be conducted in CO
   (3%). NE (16%), ND (10%), OR (4%), SD (12%), TX (2%), and WY (5%), which together with  KS (8%) and OK (5%),
   collectively produced ca. 65% of the total wild hay crop (and thus represent rangeland  grasses) in 1982.  The

                                                                                                                     45

    combined tests will adequately represent  the major rangeland and pasture regions of the U.S.
10/ Data depicting tebuthiuron residues of concern in or on fresh grass grown around roots of brush and vine clumps
    treated with a Pellet/tablet formulation  at 5.9  Ib/ai/A.  Grass species must be representative of the region  in which
    the species is grown.   Tests must be conducted in major rangeland regions of the United States.
11/ Presently, the nature of the residue in animals  is not adequately understood.  On receipt of the data requested in
    the section entitled "Nature of the Residue in Animals," the appropriate nature of tolerances for residues in
    animal products will be determined and, with consideration for any newly found metabolites of toxicological concern,
    the adequacy of the available data regarding the magnitude of the residue in fat, meat, and meat byproducts will be
    determined.
12/ Presently, the nature of the residue in animals  is not adequately understood.  On receipt of the data requested in
    the section entitled "Nature of the Residue in Animals," the need for and nature of data regarding the magnitude of
    residues in milk will be determined.

\J This is only for compounds that are organophosphate inhibitors of chlinesterase,  or related to such
   inhibitors or are metabolites of such inhibitors.   Tebuthiuron is not  an organophosphate;  therefore, a study is
not required.
2/ A subchronic oral toxicity study in a nonrodent species is not required because there is a 1-year dog study
   avalable.
3/ This study is not required for the present use pattern.
4/ Since an acute neurotoxicity study is not required, and there is no evidence of neurotoxicity in mammalian species,
   this study is not required.
5/ Data defining the absorption, distribution, and metabolites and their  excretion patterns must be submitted
   and are required.

  \J Available information on this chemical and its use pattern indicate the study is not required.
  2/ The requirement for testing with a marine or estuarine fish species will be waived because of the demonstrated low
     toxicity of tebuthiuron to fresh water fish.
  3/ Tebuthiuron is expected to transport to water with terrestrial use,  Tebuthiuron is  persistent in water (half-life
     greater than A days).
  4/ Required by the Exposure Assessment Branch, OPP,  EPA.
  T/ Needed are additional residue monitoring data for water and hydrosoil.   In 1982, the registrant was requested to
     continue (into the second year)  the monitoring of water and hydrosoil at the four study sites,  especially in the
     catchment pond at the Marietta,  Oklahoma site. Tebuthiuron is extremely persistent  in soil (half-life 11 to 61
     months).  Because of this persistence, this additional monitoring is essential in order to better determine the
     long term availability of tebuthiuron for runoff  into  aquatic systems and the likelihood of long -term buildup of
     tebuthiuron in the hydrosoil. Monitoring should  be conducted at  least  into the second year.   If additional
     monitoring was not conducted at  that time and if  no data addressing the above concerns are available, the
     registrant is required to submit a protocol for additional monitoring within 6 months. This residue moniotoring
     (for a rangeland use) should be  a multiple year study  and should  be conducted at four separate sites representing
     a wide range of climatic, edaphic, and geographical conditions.   A pelleted/tableted formulation should be used.
                                                                                                                     55

    Item 7A.  CHILD HAZARD WARNING STATEMENT - The statement
"Keep Out of Reach of Children" must be located on the front
panel above the signal word except where contact with children
during distribution or use is unlikely.  [40 CFR 162.10(h)(1)(ii)]
    «

    Item 7B.  SIGNAL WORD - The signal word (DANGER, WARNING,
or CAUTION) is required on the front panel  immediately below
the: child hazard warning statement.  [40 CFR 162.10 (h)(l)(i)]

    Item 7C.  SKULL & CROSSBONES AND WORD "POISON"  - On-products
assigned a toxicity Category I on the basis of oral, dermal,
or inhalation toxicity, the word "Poison" shall appear on the
label in red on a background of distinctly  contrasting color and
the skull and crossbones shall appear in immediate proximity to
the word POISON.   [40 CFR 162.10(h)(1)(i ) ]

    Item 7D.  STATEMENT OF PRACTICAL TREATMENT - A statement
of practical treatment (first aid or other) shall appear on
the label of pesticide products in toxicity Categories I,
II, and III.  [40 CFR 162.10(h)(1)(iii)]
                 %
    Item 7E.  REFERRAL STATEMENT - The statement "See Side

in the PHYS/CHEM Labeling Appendix. The requirement is
based on the results of the flashpoint determinations and
flame extension tests required to be submitted for all products.
These statements are to be located in the side/back panel
precautionary statements section, preceded by the heading
"Physical/Chemical Hazards."  Note that no signal word is
used in conjunction with the flammability statements.

    Item 9A.  RESTRICTED USE CLASSIFICATION - FIFRA sec. 3(d)
requires" that all pesticide formulations/uses be classified
for either general or restricted use.  Products classified
foe restricted use may be limited to use by certified applicators
or persons under their direct supervision (or may be subject
to other restrictions that may be imposed by regulation).

    In the Registration Standard, the Agency has (1) indicated
certain formulations/uses are to be restricted (Section IV
indicates why the product has been classified for restricted
use); or (2) reserved any classification decision until
appropriate data are submitted.

    The Regulatory Position and Rationale states whether
products containing this active ingredient are classified
for restricted use.  If they are restricted the draft label(s)
submitted to the Agency as part of your application must
reflect this determination (see below).

     If you do not believe that your product should be classified
for restricted use, yotf must submit any information and
rationale with your application for reregistr^tion.  During
the Agency's review of your application, your'proposed classi-
fication determination will be evaluated in accordance with
the provisions of 40 CFR 162.11(c).  You will be notified of
the Agency's classification-decision.
                             62

                          SUMMARY-4

     Classification Labeling Requirements

     If your product has been classified for restricted use,
the following label requirements apply:

     1.  All uses restricted.

         a.  The statement "Restricted Use Pesticide" must
     appear at the top of the front panel of the label.  The
     statement must be set in type of the same minimum size
     as required for human hazard signal word (see table in 40
     CFR 162.10(h)(1)(iv)

         b.  Directly below this statement on the front panel,
1     a summary statement of the terms of restriction must
;     appear (including the reasons for restriction if specified
'     in Section I).  If use is restricted to certified applicators,
     the following statement is required:  "For retail sale
     to and use only by Certified Applicators or persons
     under their direct supervision and only for those uses
     covered by the Certified Applicator's Certification."

     2.  Some but not all uses restricted.  If the Regulatory
Position and Rationale states that some uses are classified
for restricted use, and some are unclassified, several courses
of action are available:

    •.     a.  You may label the product for Restricted use.
     If you do so, you may include on the label uses that
     are unrestricted, but you may not distinguish them
     on the label as being unrestricted.

          b.  You may delete all restricted uses from your
     label and submit draft labeling bearing only unrestricted
     uses.

          c.  You may "split" your registration, i.e., register
     two separate products with identical formulations, one
     bearing only unrestricted uses, and the other bearing
     restricted uses.  To do so, submit two applications for
     reregistration, each containing all forms and necessary
     labels.  Both applications should be submitted simul-
     taneously.  Note that the products will be assigned
     separate registration numbers.

    Item 9B.  MISUSE STATEMENT - All products" must bear the
misuse statement, "It is a violation of Federal law to use
this product in a manner inconsistent with its labeling."
This statement appears at the beginning of the directions
for use, directly beneath the heading of that section.
                                 63

-------
                          SUMMARY-5

    Item 10A.  REENTRY STATEMENT - If a reentry interval
has been established by the Agency/ it must be included on
the label.  Additional worker protection statements may be
required in accordance with PR Notice 83-2, March 29, 1983.

    Item 10B.  STORAGE AND DISPOSAL BLOCK -  All labels are
required to bear storage and disposal statements.  These
statements are developed for specific containers, sizes, and
chemical content.  These instructions must be grouped and
appear under the heading "Storage and Disposal" in the directions
for use.  This heading must be set in the same type sizes as
required for the child hazard warning.  Refer to Appendix II,
STOR, PEST/DIS, and CONT/DIS to determine the storage and
disposal instructions appropriate for your products.

    Item IOC.  DIRECTIONS FOR USE - Directions for use must
be stated in terms which can be easily read and understood by
the average person likely to use or to supervise the ,use of
the pesticide.  When followed, directions must be adequate to
protect the public from fraud and from personal injury and to
prevent unreasoaable adverse effects on the environment.
[40 CFR 162.10]


                     COLLATERAL LABELING

    Bulletins, leaflets, circulars, brochures, data sheets,
flyers, or other written or graphic printed matter which *is
referred to on the label or which is to accompany the product
are termed collateral labeling.  Such labeling may not bear
claims or representations that differ in substance from those
accepted in connection with registration of the product.  It
should be made part of the response to this notice and submitted
for review.
                                 64

Chapter 1—Environmental Protection Agency


5162.10  Labeling requirements.

  •(a)  General—(1)  Contents of the label.  Every pesticide
product shall bear a label containing the information specified by
the Act and the regulations in this Part.  The contents of a
label must show clearly and prominently the following:
  (i)  The name, brand, or trademark under which the product is
sold as prescribed in paragraph (b) of bhis section;
  (ii)  The name and address of the producer, registrant, or
person for whom produced as prescribed in paragraph (c) of this
section;
  (iii)  The net contents as prescribed in paragraph (d) of this
section;
  (iv)  The product registration number as prescribed in paragraph
(e) of this section;
  (v)  The producing establishment number as prescribed in para-
graph  (f) of this section;
  (vi)  An ingredient statement as prescribed in paragraph (g) of
this section;
  (vii)  Warning or precautionary statements as prescribed in
paragraph ,(h) of this section;
  (viiij  The. directions for use as prescribed in paragraph (i)
of this section; and
  (ix)  The use classification(s) as prescribed in paragraph (j)
of this sectign.
  (2)  Prominence and legibility,  (i)  All words, statements,
graphic representations, designs or other information required on
the labeling by the Act or the regulations in this part must be
clearly legible to a person with normal vision, and must be placed
with such conspicuousness (as compared with other words, state-
ments, designs, or graphic matter on the labeling) and expressed
in such terms as to render it likely to be read and understood .
by the ordinary individual under customary conditions of purchase
and use.
  (ii)  All required label text must:
  (A)  Be set in 6-point or larger type;
  (B)  Appear on a clear contrasting background; and
  (C)  Not be obscured or crowded.
  (3)  Language to be used.  All required label or labeling text
shall  appear In the English language.  However, the Agency may
require or the applicant may propose additional text in other
languages as is considered necessary to protect the public.  When
additional text in another language is necessary,-all labeling
requirements will be applied equally to both the English and
other-language versions of the labeling.
   (4)  Placement of Label—(i)  General.  The label shall appear
on or  be securely attached to the  immediate container of the
                                     68

-------
pesticide product..  For purposes of this Section, and  the mis-
branding provisions of the Act/ "securely attached"  shall mean
that a label can reasonably be expected to remain affixed during
the foreseeable conditions and period of use.  If the  immediate
container is enclosed within a wrappe'r or outside container
through-which the la-be 1 cannot be clearly read* the  label must
also be securely attached to such outside wrapper or container,
if it is a part of the package as customarily distributed or
sold.
  (ii>  Tank cars and other bulk containers—(A)  Transportation.
While a pesticide product is in transit* the appropriate
provisions of 49 CFR Parts 170-189, concerning the transportation
of hazardous materials, and specifically those provisions con-
cerning the labeling, marking and placarding of hazardous materials
and the vehicles carrying them, define the basic Federal require-
ments.  In addition, when any registered pesticide product is
transported in a tank car, tank truck or other mobile  or portable
bulk container, a copy of the accepted label must be attached  to
the shipping papers, and left with the consignee at  the time of
delivery.
  (B)  Storage.  When pesticide products are stored  in bulk
containers, whether mobile or stationary, which remain in the
custody of the user, a copy of the label of labeling,  including
all appropriate directions for use, shall be securely  attached to
the container in the immediate vicinity of the discharge control
valve.
  (5)  False or misleading statements.  Pursuant to section
2(q)(l)(A) of the Act, a pesticide or a device declared subject
to the Act. pursuant to S 162.15, is misbranded if its  labeling is
false or misleading in any particular including both pesticidal
and non-pesticidal claims.  Examples of statements or  representations
in the labeling which constitute misbranding include:
  (i)  A false or misleading statement concerning the composition
of the product;
  (ii)  A false or misleading statement concerning the effectiveness
of the product as a pesticide or device;
  (iii)  A false or misleading statement about the value of the
product for purposes other than as a pesticide or device;
  (iv)  A false or misleading comparison with other pesticides or
devices;
  (v)  Any statement directly or indirectly implying that the
pesticide or device is recommended or endorsed by any agency of
the Federal Government;
  (vi)  The name of a pesticide which contains two or more
principal active ingredients if the name suggests one or more  but
not all such principal active ingredients even though the names
of the other ingredients are stated elsewhere in the labeling;
  (vii)  A true statement used in such a way as to give a false
or misleading impression to the purchaser;
  (viii)  Label disclaimers which negate or detract from labeling
statements required under the Act and these regulations;
                                     69

-------
  (ix)   Claims as to the safety of the pesticide^ or its  ingredients
including statements such as "safe/" "nonpoisonous/*  "noninjurious/1
"harmless" or "nontoxic to humans and pets" with or without such
a qualifying phrase as "when used as.directed"; and
  (x)  Non-numerical and/or comparative statements on the safety
of the product/ including but not limited to:
  (A)  "Contains all natural ingredients";
  (B)  "Among the least toxic chemicals known"
  (C)  "Pollution approved"
  (6)  Final printed labeling,  (i)  Except as provided  in
paragraph (a)(6)(ii) of this section/ final printed labeling must
be submitted and accepted prior to registration.  However/ final
printed labeling need not be submitted until draft label texts
have been provisionally accepted by the Agency.
  (ii)  Clearly legible reproductions or photo reductions will be
accepted for unusual labels such as those silk-screened directly
onto glass or metal containers or large bag or drum labels.  Such
reproductions must be of microfilm reproduction quality.
  (b)  Name/ brand/ or trademark.  (1)  The name/ brand/ or
trademark under which the pesticide product is sold shall appear
on the front panel of the label.
  (2)  No name/ brand/ or trademark may appear on the label which:

  (ii)  Has not been approved by the Administrator through
registration or supplemental registration as an additional name
pursuant to $-162.6(b)(4).
  (c)  Name and address of producer/ registrant/ or person for
whom produced.  An unqualified name and address given on the
label shall be considered as the name and address of  the producer.
If the registrant's name appears on the label and the registrant
is not the producer/ or if the name of the person for whom the
pesticide was produced appears on the label/ it must  be qualified
by appropriate wording such as "Packed for ***," "Distributed by
***
/
       or "Sold by ***" to show that the name is not that of the
producer.
   (d)  Net weight or measure of contents.  (1)  The net weight or
measure of content shall be exclusive of wrappers or other
materials and shall be the average content unless explicitly
stated as a minimum quantity.
   (2)  If the pesticide is a liquid/ the net content statement
shall be in terms of liquid measure at 68*P (20*C) and shall be
expressed in conventional American units of fluid ounces/ pints/
quarts/ and gallons.
   (3)  If the pesticide is solid or semisolid/ viscous or
pressurized/ or is a mixture of liquid and solid/ the net content
statement shall be in terms of weight expressed as avoirdupois
pounds and ounces.
   (4)  In all cases/ net content shall be stated in terms of the
largest suitable units/ i.e., "1 pound 10 ounces" rather than
"26 ounces. "                                     •
                               70

-------
  (5)  In addition to the required units specified,  net  content
may be expressed in metric units.
  (6)  Variation above minimum content or around an  average  is
permissible only to the extent that it represents deviation
unavoidable in good manufacturing practice.  Variation below a
stated minimum is not permitted.  In no case shall the average
content of the packages in a shipment fall below the stated
average content.
  (e)  Product registration number.  The registration number
assigned to the pesticide product at the time of registration
shall appear on the label, preceded by'the phrase "EPA Registration
No.," or the phrase "EPA Reg. No."  The registration number  shall
be set in type of a size and style similar to other print on that
part of the label on which it appears and shall run  parallel to
it.  The registration number and the required identifying phrase
shall; not appear in such a manner as to suggest or imply .
recommendation or endorsement of the product by the Agency.
  (f)'  Producing establishments registration number.  The producing
establishment registration number preceded by the phrase "EPA
Est.V of the final establishment at which the product was produced
may appear'in any suitable location on the label or  immediate
container.  It must appear on the wrapper or outside container of
the package if the EPA establishment registration number on  the
immediate.container cannot be clearly read through such  wrapper
or container?  •     -     -         -   •
  (g)  Ingredient statement—(1)  General.  The label of each
pesticide, product must bear a statement which contains the name
and percentage by weight of each active ingredient,  the  total
percentage by weight of all inert ingredients; and if the pesticide
contains arsenic in any form, a statement of the percentages of
total and water-soluble arsenic calculated as elemental  a'rsenic.
The active ingredients must be designated by the term "active
ingredients" and the inert ingredients by the term "inert
ingredients," or the singular forms of these terms when  appropriate.
Both terms shall be in the same type size, be aligned to the same
margin and be equally prominent.  The statement "Inert Ingredients,
none" is not required for pesticides which contain 100 percent
active ingredients.  Unless the ingredient statement is  a complete
analysis of the pesticide, the term "analysis" shall not be  used
as a heading for the ingredient statement.
   (2)  Position of ingredient statement.  (i)  The ingredient
statement  is normally required on the front panel of the label.
If there  is an outside container or wrapper through  which the
ingredient statement cannot\ be clearly read, the ingredient
statement must also appear on such outside container or  wrapper.
If the size or form of the package makes it impracticable to place
the  ingredient statement on the front panel of the label, permission
may  be granted for the ingredient statement to appear elsewhere.
   (ii)  The text of the  ingredient statement must run parallel
with other text on the panel on which it appears/ and must be
clearly distinguishable  from and must not be placed  in the body
of other  text.
                                       71

-------
  (3)   Names to be used in ingredient statement.  The name  used
for each ingredient shall be the accepted common  name,  if there
is one/ followed by the chemical name.  The common name may be
used alone only if it is well known.  If no common name has been
established, the chemical name alone'shall be used.  In no  case
will the use of a trademark or proprietary name be permitted unless
such name has been accepted as a common name by the Administrator
under the authority of Section 25(c)(6).
  (4)   Statements of percentages.  The percentages of ingredients
shall be stated in terms of weight-to-weight.  The sum of per-
centages of the active and the inert ingredients  shall be 100.
Percentages shall not be expressed by a range of  values such as
"22-25%."  If the uses of the pesticide product are expressed as
weight of active ingredient per unit area, a statement of the
weight of active ingredient per unit volume of the pesticide
formulation shall also appear in the ingredient statement.
  (5)   Accuracy of stated percentages.  The percentages given
shall'be as precise as possible reflecting good manufacturing
practice.  If there may be unavoidable variation  between manu-
facturing batches, the value stated for each active ingredient
shall be the lowest percentage which may be present.
  (6)  Deterioration.  Pesticides which change in chemical
composition significantly must meet the following labeling  re-
quirements;:
  (i)  In cases where it is determined that a pesticide formulation
changes* chemical composition significantly, the product must bear
the following statement in a prominent position on the label: "Not
for sale or use after [date]."
  (ii)  The product must meet all label claims up to the expiration
time  indicated on the label.
  (7)  Inert ingredients.  The Administrator may  require -the name
of any inert ingredient(s) to be listed in the ingredient statement
if he determines that such ingredient(s) may pose a hazard  to man
or the environment.
  (h)  Warnings and precautionary statements.  Required warnings
and precautionary statements concerning the general areas, of
toxicological hazard including hazard to children, environmental
hazard, and physical or chemical hazard fall into two groups; those
required on the front panel of the labeling and those which may
appear elsewhere.  Specific requirements concerning content,
placement, type size, and prominence are given below.
  (1)  Required front panel statements.  With the exception of the
child hazard, warning statement, the text required on the front
panel of the label is determined by the Toxicity  Category of the
pesticide.  The category is assigned on the basis of the highest
hazard shown by any of the indicators in the table below:
                                     72

  (i)  Human hazard signal word.--(A)  Toxicity Category I.  All
pesticide products meeting the criteria of Toxicity Category I
shall bear on the front panel the signal word "Danger.". In
addition if the product was assigned to Toxicity Category I on
the basis of its oral, inhalation or dermal toxicity (as distinct
from skin and eye local effects) the word "Poison" shall appear
in red on a background of distinctly contrasting color and the
skull and crossbones shall appear in immediate proximity to the
word "poison."
  (B)  Toxicity Category II.  All pesticide products meeting the
criteria of Toxicity Category II shall bear on the front panel'
the signal word "Warning."
  (C)  Toxicity Category III.  All pesticide products meeting the
criteria of Toxicity Category III shall bear on the front panel
the signal word "Caution."
  (D)  Toxicity Category IV.
All pesticide products meeting the
criteria of Toxicity Category IV shall bear on the front panel
the signal word "Caution."
                                   73

-------
  (E)  use of signal words.  Use of any signal word(s)  associated
with a higher Toxicity Category is not permitted except when  the
Agency determines that such labeling is necessary  to prevent
unreasonable adverse effects on man or the environment.   In no
case shall more than one human hazaro" signal word  appear  on the
front panel of a label.
  (ii)  Child hazard warning.  Every pesticide product  label  shall
bear on the front panel the statement "keep out of reach  of
children."  Only in cases where, the likelihood of  contact with
children during distributionr marketing, storage or use is
demonstrated by the applicant to be extremely remoter or  if the
nature of the pesticide is such that it is approved for use on
infants or small children, may the Administrator waive  this
requirement.
  (iii)  Statement of practical treatment—tA)  Toxicity
Category I.  A statement of practical treatment (first  aid or
other) shall appear on the front panel of the label of  all
pesticides falling into Toxicity Category I on the basis  of oral,
inhalation or dermal toxicity.  The Agency may, however,  permit

    extremes, excessive moisture or humidity, heat, sunlight,
    friction, or contaminating substances or media.
     »
2.  Physical requirements of storage which might adversely
    affect the container of the product and its ability to
    continue to function properly.  Requirements might include
    positioning of the container in storage, storage or damage
    due to stacking, penetration of moisture, and ability to
    withstand shock or friction.

3.  Specifications for handling the pesticide container,
    including movement of container within the storage area,
    proper opening and closing procedures (particularly for
    opened containers), and measures to minimize exposure
    while opening or closing container.

    any way, or if the pesticide is leaking or has been
    spilled, and precautions to minimize exposure if damage occurs,

5.  General precautions concerning locked storage, storage in
    original container only, and separation of pesticides
    during storage to prevent  cross-contamination of other
    pesticides, fertilizer, food, and feed.

6.  General storage instructions for household products should
    emphasize storage in original container and placement in
    locked storage areas.

                            BIBGUIDE-1

              GUIDE TO USE OF THIS BIBLIOGRAPHY
1.  CONTENT OF BIBLIOGRAPHY.   This bibliography contains
    citations of all studies  considered relevant by EPA in
    arriving at the positions and conclusions stated elsewhere
    in the Standard.  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, will  be  included.

2.  UNITS OF ENTRY.  The unit of entry in this bibliography
    is called a "study.*  In  the case of published materials,
 i   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 attempted also 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 at any  time 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 a further explana-
    tion.  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 identifier 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
    standards of the American National Standards Institute
    (ANSI), expanded to provide for certain special needs.

    When no individual was identified, the Agency has
    shown an identifiable laboratory or testing facility
    as author.   As a last resort, the Agency has shown
    the first submitter as author.

b.  Document Date.  When the date appears as four digits
    with no question marks,  the Agency took it directly
    from the document.  When a four-digit date is followed
    by a question mark, the bibliographer deduced the
    date from evidence in the document.  When the date
;    appears as  (19??), the Agency was unable to determine
i    or estimate the date of the document.

c.  Title.  In  some cases, it has been necessary for
    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 fol-
    lowing 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,
         following the phrase "submitted by."  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," standing 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.
         For example, within accession number 123456, the
         first  study would be 123456-A; the second, 123456-
         B; the 26th, 123456-Z; and the 27th, 123456-AA.

          GENERAL WARNINGS AND LIMITATIONS;  Tebuthiuron is used in noncroplands and
          paature/rangelands to control grasses, broadleaf weeds, brush and woody
          plants.  When applied to the soil, this chemical is* absorbed by the roots
          of plants.  Effects are slow to appear and will not become apparent until
          sufficient moisture has carried the chemical into the root zone.  Applica-
          tions should be made prior to rainfall.  A minimum of 1 to 1.5 inches of
          rainfall is required.  Time required for plant control is dependent on
          soil type, amount of rainfall, and depth of species rooting.  Some species
          may go through several defoliations and refoliations over a period of 1
          to 3 years before dying.  Use a mechanical spreader or other device which
          will spread the required dosage evenly over the area to be treated.  Do
          not apply directly to lakes, ponds, or streams or contaminate water
          sources by cleaning of equipment or disposal of wastes.  Do not apply on
          field crops.  Do not apply when winds are gusty or to areas where soil
          movement by water erosion and/or natural or mechanical means ia likely.
          Do not apply when the ground is frozen, snow covered, or saturated with
          water.  Do not make broadcast applications where forage or maintenance of
          grass cover is desired.  Desirable plants with feeder roots extending into
          treated areas may be seriously injured.  Injury to most herbaceous peren-
          nials is reduced when treatment is applied when this vegetation is dor-
          mant.  Do not use on prickly pear, cholla, cactus or sassafras.  In areas
          treated with 4 pounds active ingredient or less, livestock may be allowed
          to graze and grass may be cut for hay 1 year after application. For band
          treatments, reduce dosages proportionately.  Band treatments in areas of
          steep terrain should be applied across existing slopes to prevent soil
          erosion.  Cut brush should be allowed to resprout to a height of 5 feet
          before treatment.  Requires actively growing plant to be effective.

Registration number 001471-00123 contains  a supplemental label claiming
use of aerial applications for brush and woody plant control.   There are
no specific sites listed on the supplemental label.  The assumption was
made that this claim referred to all sites listed on the latest acceptable
label.  However, aerial applications in ditchbanks does not seem feasible
considering the irrigation and potable water statements and has been omit-
ted for this site.

*These pests could not be located in the EPA generated pest listing dated
April, 1985.  Dennis Szuhay is looking into this problem - as  soon as
pest codes are found they will be Inserted.
