                       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,1 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 and Compendium of Acceptable
Uses may be obtained from the OPP Public Docket.   Write to
OPP Public Docket,  Field Operations Division (H7506C),
Office of Pesticide Programs, EPA, 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.  Submittal 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 unreasonable adverse effects of a pesticide at any
                         - 2 -

-------
time that they become aware of such information.  Registrants
must notify the Agency of any information, including interim
or preliminary results of studies, if that information
suggests possible adverse effects on man or the environment.
This requirement is independent of the specific time
requirements imposed by EPA for submittal of completed
studies called in by the Agency and continues as long as the
products are registered under FIFRA.

-------
                        C.  BACKGROUND
Three Data Call-in (DCI) Notices have been issued for propazine.
The first, in August 1983, required chronic toxicity data.
Studies submitted in response to this DCI have been reviewed
and are discussed in this document.  Many of the submitted
studies were unacceptable and additional chronic data continue
to be required.

In July 1984, the Agency issued a DCI Notice for groundwater
data for propazine.  This Notice was issued for chemicals
which may have the potential to contaminate groundwater based
on such factors as the chemical's structure, solubility and
use patterns.

Based on the Agency's review of the data submitted in response
to the July 1984 DCI, it was determined that propazine and/or
its degradate(s) do have the potential to leach into groundwater
However, the Agency decided that additional data were needed to
define further the extent of the groundwater problem, and, in
April 1988, issued the third DCI Notice.  This Notice required
a small-scale retrospective groundwater monitoring study on
propazine.

Based on its potential to contaminate groundwater, propazine
has been included in EPA's National Pesticide Survey.

In response to the 1988 DCI Notice, the manufacturer of
propazine, Ciba-Geigy, elected to cancel its registrations of
propazine.  To date, no other registrant has committed to
generate data required by that Notice.  All products have
either been cancelled or suspended.

                   Til.  AGENCY ASSESSMENT
                         A.  SUMMARY

Based on a review of the available data on propazine, the
Agency has reached the following conclusions regarding this
chemical.  These data are discussed in more detail in the
following sections.

1.  Propazine has low acute toxicity.   It is not teratogenic
    in the rat.  It is, however, oncogenic and the Agency has
    classified propazine as a Group C oncogen (potential
    human carcinogen) based on positive findings in the rat.

2.  Propazine has been designated as a chemical with a high
    potential for leaching into groundwater and is included in
    the EPA National Pesticide Survey.

3.  The Agency will not, at this time, formulate specific
    regulatory positions regarding propazine unless a registrant
    commits to generate data in support of this chemical.


                 B.  TOXICOLOGICAL ASSESSMENT

The Agency has reviewed the available acceptable toxicological
data for propazine.  The results of that review are set forth
below:

ACUTE TOXICITY.  Propazine has low acute oral toxicity, with
an LD5Q for rats of >5 g/kg (Toxicity Category IV).  It has
moderate acute dermal and inhalation toxicity, with an acute
dermal LD5Q of of >2 g/kg for rabbits (Toxicity Category III)
and an acute inhalation LC5Q of >2.1 mg/L/4 hour for rats
(Toxicity Category III).

Propazine is moderately irritating to rabbit eyes.  No corneal
opacity was observed but some conjunctival irritation was
observed at 24 hours with clearing by day 4 (Toxicity Category
IV).  It is moderately irritating to rabbit skin demonstrating
a Primary Irritation Score of 3.9/8.0 with erythema, eschar,
and edema.  Improvement was noted by 72 hours.  (Toxicity
Category III)

SUBCHRONIC TOXICITY.  No acceptable subchronic studies are
available.  However, because an acceptable chronic rat study
is available and a nonrodent chronic study is required, oral
subchronic studies are not required.

-------
Since the use-of propazine would result in repeated human
skin contact, but of a limited frequency and duration, a
21-day dermal toxicity study is required.  Other subchronic
studies are not required.

CHRONIC TOXICITY.  Sufficient data are available to satisfy
the data requirements for a chronic feeding study in a rodent
species (rat).  A chronic feeding study in nonrodents is
required.

In the rat study, 60 male and 60 female CD rats/dosage level
were given 0, 3 ppm (0.15 mg/kg/day), 100 ppm (5.0 mg/kg/day),
and 1000 ppm  (50 mg/kg/day) of propazine in their diets for 2
years.  Generally, there were no treatment-related toxicity
signs, or changes in hematology, clinical chemistry, or
urinalysis.  Body weights of both males and females of the
high-dose groups were significantly decreased in comparison
to controls, as well as mean food consumption.  There was an
increase in subcutaneous masses and nodules in females of the
1000 ppm dose group which correlated with the increased
microscopic findings of mammary gland tumors (see below).
The systemic NOEL was designated as 100 ppm based on the
depression in body weights in the high-dose male and female
groups.

ONCOGENICITY.  There are sufficient data available to satisfy
the data requirements for oncogenicity studies.

In the rat study (discussed above), gross necropsy showed an
increase in subcutaneous masses and nodules in females of the
1000 ppm dose group, which correlated with an increase in
mammary neoplasms.  These neoplasms included benign tumors
(adenomas, fibroadenomas) and malignant tumors (adenocarcinomas,
papillary carcinomas).

In a mouse study, 60 male and 60 female CD-I mice/dosage
levels were given 0, 3 ppm (0.45 mg/kg/day), 1000 ppm (150
mg/kg/day, and 3000 ppm (450 mg/kg/day) of propazine in their
diets for 2 years.  Propazine was not found to be oncogenic
in this study.  There were increased incidences  of non-
neoplastic lesions in high-dose males of hemosiderin-laden
macrophages and in high dose females of myocardial degeneration.
The systemic NOEL was 1,000 ppm.

In accordance with the Agency's Guidelines for Assessing
Carcinogenic Risk, EPA has classified propazine  as a Group C
compound (potential human carcinogen).   This classification
is based on the following:

In the rat study, female rats developed benign and malignant
mammary tumors.   A statistically significant dose-related trend
                            - 7 -

-------
was found for malignant and benign tumors, combined, and a
statistically significant pairwise comparison was found
for high dose vs. control for malignant and benign, combined.
Although these tumors were significant only at the high dose,
at which the maximum tolerated dose was apparently achieved
or slightly exceeded, the Agency believes that they were,
nevertheless, convincing since the increase in these tumors
in females at the high dose exceeded that of historical
controls.

Structure activity on related triazines provides support
for the association of mammary tumors with this class of
chemicals.  Propazine is structurally related to simazine,
cyanazine, atrazine and terbutryn.  Atrazine and terbutryn
have both been classified as Group C oncogens (mammary tumors
in rats).

Propazine induced a dose-related, positive response (without
metabolic activation) in Chinese hamster cells (and a weak
non-dose-related one with activation).  Propazine was negative
in a nucleus anomaly assay and in a DNA damage/repair assaay
in rat hepatocytes.

Propazine was negative for oncogenicity in mice.  For
malignant lymphomas in females, multiplicity of tumors per
animal (tumor load) was enhanced relative to dose.  This
suggests that increased or enhanced metastatis factors may be
operating in the mouse.

Although the Agency determined that a Group C classification
is appropriate for propazine, EPA has concluded that quanti-
tative risk assessment is not warranted.  This conclusion is
based on the fact that the tumors observed in the rat study
occurred in only one sex, were mostly benign, and were
significantly increased only at the highest dose.

TERATOGENICITY.   There is an acceptable teratogenicity study
in the rat.  A developmental toxicity study in a second
species (rabbit) is required.

In the rat study, propazine was administered to groups of 25
female Sprague-Dawley rats at dosage levels of 0, 10, 100
and 500 mg/kg/day.  It was not teratogenic at dosages up to
500 mg/kg/day, the highest dose tested (HOT).  Maternal
toxicity was observed in the mid- and high-dose females as
decreased food consumption and decreased body weight gain.
Additionally, high-dose females exhibited periods of sali-
vation (clear) during gavage.  The NOEL for maternal toxicity
was 10 mg/kg/day.

-------
Developmental toxicity was observed at the high dose as
increased 14th ribs, incomplete ossification of skeletal
structures and decreased fetal body weight.  At the mid-dose,
delayed ossification of the interparietals was observed.  The
NOEL for developmental toxicity was 10 mg/kg/day.

REPRODUCTION.  There are sufficient data available to satisfy
the requirements for a reproductive toxicity study for propazine.

In a three-generation, 2-litter per generation, study, male
and female CD rats were continuously given  propazine in
their diets at dosage levels of 0, 3 ppm (0.15 mg/kg/day),
100 ppm (5 mg/kg/day), and 1000 ppm (50 mg/kg/day).  No
compound-related effects for clinical signs or mortality were
observed during the study.

At the 1000 ppm dosage level, a depression in body weight was
observed in both male and female parental animals.  Food
consumption was reduced at the high dose in the Fg and F2
females and at all dosage levels of the F]_ and F2 male groups.
No compound-related effects in male or female fertility, gestation
length, pup viability, and pup survival were observed.  Mean
body weights of male and female pups at day 21 of lactation
were significantly reduced at 1000 ppm in the F^, F2a, F2b'
F3a, and F3b litters.  Altered absolute or relative organ
weights were observed in all parental groups at the high dose
level.  Fg males showed an increased relative testicular and
relative heart weight, F]_ males displayed an increased relative
liver and heart weight, and F2 males and females had decreased
absolute liver weights while the F2 males had decreased
relative liver weight, relative testicular weight, and kidney
weight.  No histological findings attributable to propazine
were observed in parental or weanling animals.  The reproductive
NOEL is 100 ppm, based on the depression in pup weights at 21
days postpartum in the FIJ-,, ?2a' F2b'  F3a'  and F3b litters.

MUTAGENICITY.  There are sufficient data available to satisfy
the mutagenicity data requirements.

In a gene mutation assay, propazine was tested in V79 Chinese
hamster cells with and without microsomal activation.  It
produced a dose-related positive mutagenic response without
metabolic activation and a weak (non-dose-related) positive
response with metabolic activation.

In a structural chromosomal aberration assay, propazine was
administered in the diet to groups of  six male and six female
Chinese hamsters.   The cells displaying anomalies on nuclei
in treated cells did not differ significantly from the negative
controls.   Propazine was not considered mutagenic in this
assay.
                           - 9 -

-------
DNA damage/repair assays were performed on rat hepatocytes
with propazine.  The mean number of silver grains per nucleus
in the vehicle control and treated cells was not markedly
different.  Propazine was not mutagenic under the conditions
of this assay.

METABOLISM.  There are no acceptable metabolism studies;
a general metabolism study is required.


                  C.  OTHER SCIENCE FINDINGS

ECOLOGICAL EFFECTS.   The Agency has limited ecological effects
data.

Based on an acceptable fish acute toxicity study on
technical propazine, with an LC5Q of 16.5 ppm for Rainbow
trout, propazine can be characterized as slightly toxic to
coldwater fish.

In the partially acceptable avian dietary study with a
formulated product,  an LC5Q of 32000 ppm was reported for
Mallards, which indicates that the compound is practically
nontoxic for waterfowl.  There are, however, currently no
requirements for studies on formulated products.

There are sufficient data to characterize propazine as
relatively nontoxic  to honey bees when bees are exposed to a
direct treatment.

Based on use patterns, estimated concentrations and the
available toxicity data, EPA has determined that the use of
propazine will not pose a hazard to endangered wildlife (fish
and avian) or plants.

ENVIRONMENTAL FATE.   Available data are insufficient to fully
assess the environmental fate of propazine.

In an acceptable aerobic soil study, propazine degraded with
a half-life of 12-24 weeks in nonsterile loamy sand soil
incubated in the dark at 25°C.  In sterile loamy sand soil,
propazine degraded with a half-life of 8-12 weeks in the
dark at 25°C.

In an acceptable anaerobic soil study, propazine degraded
with a half-life of  8 weeks in nonsterile loamy sand soil
incubated anaerobically in the dark at 25°C following 4 weeks
of aerobic incubation.

In an acceptable leaching and absorption/desorption study,
propazine was mobile in sandy loam, loam, and clay loam soils,
and was very mobile  in loamy sand soil.
                             - 10 -

-------
The following information is based on studies which, while
not acceptable for fulfilling data requirements, do provide
supplemental information on propazine:

Propazine was stable to hydrolysis during 28 days of incubation
at 30°C in aqueous solutions buffered at pH 7 and 9.  In the
pH 5 buffered solution, the half-life was >28 days.  It was
relatively stable to photolysis in aqueous solutions irradiated
with natural sunlight.

Propazine was very mobile in loamy sand and loam soils;
mobile in sandy loam, silt soils, and sand soil; and slightly
mobile in loam soil.

Propazine dissipated with a half-life of OO-149 days and <31
days in sandy loam soil in tests conducted in two different
locations.  It dissipated with a half-life of 60->357 days in
silt loam soil.

Groundwater.  Based on the available data, propazine is
persistent, moderately mobile and stable to hydrolysis,
photolysis and microbial degradation, demonstrating a potential
to contaminate groundwater.  Propazine has been detected in
groundwater samples in a total of 8 states.  The maximum
concentrations found were 20 ppb in surface water and 300 ppb
in groundwater.

Reentry.  Based on the low acute toxicity of propazine and
its use patterns, the Agency finds that reentry data are not
required.

Spray Drift.  No data are available to evaluate the spray
drift potential of propazine and data are required.

PRODUCT CHEMISTRY.  EPA has evaluated the available data
which identify the ingredients, materials and manufacturing
process and provide information on the physical and chemical
properties of propazine.  Since propazine is a secondary
amine, there is a concern regarding potential for nitrosoamine
contamination.  However, currently available data
are insufficient to thoroughly evaluate this potential
contamination.


                  D.  TOLERANCE REASSESSMENT

Tolerances have been established for negligible residues of
propazine in or on sweet sorghum and its fodder, forage and
grain at 0.25 ppm (40 CFR 180.243).

EPA has evaluated the residue data supporting these tolerances.
The results of this evaluation follow.
                           -  11 -

-------
Residue Data.  The nature of the residues in both plants and
animals are not adequately understood.   Additional data are
required.  Data on storage stability are unavailable.  Adequate
analytical methods are available for data collection pertaining
to residues of propazine.  Additional methods may be required
if metabolism studies indicate that additional metabolites
constitute residues of toxicological concern in plants or
animals.

Sufficient data are available to ascertain the adequacy of
the established tolerances for residues of propazine in or on
sorghum fodder, sorghum forage, sorghum grain, and sweet
sorghum.  However, processing studies are required for grain
sorghum and sweet sorghum.

There are no Canadian, Mexican or Codex MRL tolerances for
sorghum; therefore, no compatibility questions exist.

Toxicology Data.  The Provisional Acceptable Daily Intake
(PADI) for this chemical is 0.02 mg/kg/day, based on the
2-year rat feeding/oncogenicity study.   The systemic NOEL
was set at 100 ppm (5 mg/kg).  The safety factor used was
300 based on an uncertainty factor of 100 to account for
inter- and intra-species differences with an additional factor
of 3 to account for the  incompleteness of the chronic data base
since the one-year dog feeding study may yield a more sensitive
toxicological endpoint.

The Theoretical Maximum  Residue Contribution  (TMRC)  for the
U.S. population average  is 0.0003 mg/kg/day, equivalent to
1.7 percent of the PADI.  The TMRC  is based on published  as
well as  pending tolerances.

           IV.   REGULATORY POSITION AND RATIONALE
            A.  REGULATORY POSITION AND RATIONALE

Position.  The Agency has determined that it is not necessary,
at this time, to formulate specific regulatory positions
regarding propazine.  Should it become necessary to establish
individual positions, based on review and evaluation of the
available data and other relevant information, the Agency
would consider regulatory positions regarding such areas as
special review, tolerances and groundwater.

EPA will, however, remove the reference to the designation
"negligible residue," a term which is now considered obsolete,
from the tolerance expression in 40 CFR 180.243 at such time
as the regulation may be amended in the future or as soon as
practicable.  In the event that all registrations for food
uses of this pesticide are cancelled prior to the amendment
of the tolerance regulation, the tolerances will be scheduled
for revocation and the need to amend the regulation will have
become moot.

Rationale:  In April 1988, the Agency issued a DCI Notice to
the registrants of propazine products requiring a small-scale
retrospective groundwater monitoring study.  In response to
that Notice, the manufacturer of propazine elected to cancel
its registrations of propazine.  No other registrant has
committed to generate the required data, and, therefore, all
products have been cancelled or suspended.  Since suspended
products cannot be marketed, there is no reason to impose
new label requirements which apply only to products introduced
into the marketplace after issuance of a Standard.

If a registrant commits to generate these data and complies
with the requirements of FIFRA, as set forth in this document,
the Agency will formulate specific regulatory positions
regarding this chemical.  However, EPA believes revision to
the tolerance expression, if the suspended registrations are
not cancelled, is appropriate to eliminate obsolete terminology.


                B.  CRITERIA FOR REGISTRATION

To be registered or reregistered under this Standard, products
must contain this pesticide, bear required labeling, and
conform to the product composition, acute toxicity limits,
and use pattern requirements listed in this document.
                             - 13 -

-------
               C.  ACCEPTABLE RANGES AND LIMITS

Product Composition Standard.  To be registered or reregistered
under this Standard, manufacturing-use products (HP's) must
contain this pesticide.  Each MP formulation proposed for
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 0.1 percent.

Acute Toxicity Limits.   The Agency will consider registration
of technical grade and MP's containing this pesticide provided
that the product labeling bears appropriate precautionary
statements for the acute toxicity category in which each
product is placed.

Use Patterns.  To be registered under this Standard, MP's may
be labeled for formulation into end-use products for acceptable
use patterns.  However, no use may be included on the label
where the registrant fails to agree to comply with the data
requirements in Table A for that use pattern.
                         D.  LABELING

Should a registrant commit to generate data and maintain
product registrations for propazine, labeling must be updated.
Once a registrant has committed, the Agency will provide
specific labeling statements unique to propazine.  In addition,
the following standard labeling requirements will apply.

All products must bear appropriate labeling as specified in
40 CFR 156.10, PR Notices 83-2, 83-3 and below.  Appendix II
contains information on label requirements.

The ingredient statement must list the active ingredient as:

    Propazine (2-chloro-4,6-bis(isopropylamino)-
            s-triazine)  	   %

Time Frames for Compliance.  Pesticide products containing
propazine as an active ingredient may not be released for
shipment by the registrant after December 1989, unless the
product bears an amended label which complies with the require-
ments of FIFRA as set out in this Standard.

Pesticide products containing propazine as an active  ingredient
may not be distributed or sold by any person after December
1990, unless the product bears an amended label which complies
with the requirements of this Standard.
                            - 14 -

-------
            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 submittal 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:

     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 B.2

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

     4.   Administrative requirements (application forms,
          Confidential Statement of Formula, data
          compensation provisions) associated with
          reregistration.

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

     1.   The data requirements listed in Table A.
     2Data 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
Registration Standard.  Table B lists product-specific data
applicable to manufacturing-use products.  The data in Tables
A and B need not be submitted by an end-use producer who is
eligible for the generic data 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 noh require the submittal of product-specific data for
end-use products at this time.  Therefore, most Registration
Standards do not contain a Table C.
                            - 15 -

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

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 eligible for the generic data exemption,3 the
          data requirements listed in Table C.

     3.   If not eligible for the generic data exemption, the
          data requirements listed in Table A and the data
          requirements listed in Table C.

     4.   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:

     1.   If not eligible for the generic data exemption, the
          data requirements listed in Tables A and C.

     2.   If eligible for the generic data exemption, the
          data requirements listed in Table C.

     3.   The labeling requirements specified for end use
          products in Section IV.
     3If you purchase from another producer and use as the
source of your active ingredient only EPA-registered
products, you are eligible for the generic data exemption for
generic data concerning that active ingredient (Table A) and
product-specific data for the registered manufacturing use
product you purchase (Table B).

     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-vise producers lose the exemption, and become subject
to the data requirements in TabJe A.


                            - 16 -

-------
       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
registration 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
(unless 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 152.85) to submit
generic data in response to a DCI 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 submittal or citation of the data
listed in this Registration Standard.
                            - 17 -

-------
     If you are not__aaw.._=eligAb.le,.J[or_a. generic data
exemption, you may qualify for one if you change youF 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 Generic Data
Exemption Statement.

     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
submittal 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 DCI 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
                             - 18 -

-------
who will be submitting the data that you may rely upon its
submittal. 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, as part of your 90-day response.  The
request must include the following information:

     a.   A list of the members of the consortium;
     b.   The name and address of the designated
          representative of the consortium, with whom EPA
          will correspond 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
          consortium will be generating or submitting.

     The Agency will assign a number to the consortium, which
should be used on all data submittals by the consortium.

     3.  You have attempted to enter into an agreement to
jointly develop data, but no other registrant has accepted
your offer.  You request that EPA not suspend your
registration for non-compliance with the DCI.  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
Development of Data" (EPA Form 8580-6, 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:

     [Your company name] offers to share in the burden of
producing the data required pursuant to FIFRA sec.


                              - 19  -

-------
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 requirement applies, EPA does not anticipate
that many waivers will be granted.  A request for waiver does
not extend the timeframes for developing required data, and
if your waiver request is denied, your registration may be
suspended if you fail to submit the data.  The Agency will
respond in writing to your request for a waiver.

     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 regis-
tration of your product(s) for which the data are needed.

E.   Registrant Requests Regarding Data Requirements and
     Agency Responses

     All requests for modification of data requirements
(inapplicability, waiver), approval of protocols or protocol
                             - 20 -

-------
changes, or time extensions must be submitted in writing.
The original requirement remains in effect unless the Agency
has notified you in writing that it has agreed to a change in
the requirement.  While being considered by the Agency, such
requests for changes in the requirements do not alter the
original requirements or extend the time allowed for meeting
the requirement.

F.  Test Protocols and Standards

     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.  All testing must
be conducted in accordance with applicable Good Laboratory
Practices regulations in 40 CFR Part 160.

     The Pesticide Assessment Guidelines, 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
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, B.C.
20006.

G.  Procedures for requesting a change in test 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 submittal
of the data, nor will extensions generally be given to
                             - 21 -

-------
conduct studies due to submittal of inappropriate protocols.
The Agency will respond in writing to your request for
protocol approval or change.

H.  Procedures for requesting extensions of time.

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

     EPA will view failure to request an extension before the
data submittal 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.

     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.  The Agency will
respond in writing to any requests for extension of time.

I.  Data Format and Reporting Requirements

     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).  All studies must be submitted in the
form of a final report; a preliminary report will not be
considered to fulfill the submittal requirement.

J.   Existing stocks provision upon suspension or
     cancellation.

     The Agency has determined that if a registration is
suspended for failure to respond to a DCI request under FIFRA
sec. 3(c)(2)(B), an existing stocks provision for the
registrant 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 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
                            - 22 -

-------
stocks and your estimate of the time required for their sale
or distribution; and

     2.   Demonstration that such a provision would be
consistent with the provisions of FIFRA.
                             -  23 -

-------
   VII.  REQUIREMENT  FOR  SUBMISSION  OF  PRODUCT-SPECIFIC DATA

     Under its DCI authority, EPA has determined that
certain product-specific data are required to maintain your
registrations in effect.  Product-specific data are derived
from testing using a specific formulated product, and, unlike
generic data, generally support only the registration of that
product. All such data must be submitted by the dates
specified in this Registration Standard.

     If you have a manufacturing use product, these data are
listed in Table B.  If you have an end use product, the data
are listed in Table C.  As noted earlier, the Agency has
decided that it will not routinely require product-specific
data for end use products at this time.  Therefore, Table C
may not be contained in this Registration Standard; if there
is no Table C, you are not required to submit the data at
this time.

     In order to comply with the product specific data
requirements, you must follow the same procedures as for
generic data. See Section VI.D through J.  You should note,
however, that product chemistry data are required for every
product, and the only acceptable responses are options
VI.D.I. (submit data) or VI.D.6. (cancellation of
registration).

     Failure to comply with the product-specific data
requirements for your products will result in suspension of
the product's registration.
                            - 24 -

-------
    VIII.  REQUIREMENT  FOR  SUBMITTAL 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 156.10 (see Appendix II -
LABELING and SUMMARY).  In addition, labeling language
specific to products containing this pesticide is specified
in Section IV.D of this Registration Standard.  Responses to
this Registration Standard must include draft labeling for
Agency review.

     Labeling must be either typewritten text on 8-1/2 x 11
inch paper or a mockup of the labeling suitable for storage
in 8-1/2 x 11 files.  Draft labeling must indicate the
intended colors of the final label, clear indication of the
front panel of the label, and the intended type sizes of the
text.

     If you fail to submit revised labeling as required,
which complies with 40 CFR 156.10 and the specific
instructions in Section IV.D., EPA may seek to cancel the
registration of your product under FIFRA sec. 6.
                             - 25 -

          Washington, B.C.  20460

          Attn:  Propazine Registration Standard

     All submittals in response to this Registration
Standard are non-fee items, including 90-day responses,
protocols and waiver requests, data, and revised labeling.
Submittals must be clearly identified as being in response to
the Registration Standard.  Under no circumstances may
Registration Standard responses be combined with other types
of filings for which fees are required.

A.   Manufacturing Use Products (MUPs) containing the subject
     pesticide as sole active ingredient.

     1.  Within 90 days from receipt of this document, you
must submit for each product subject to this Registration
Standard:

     a.   Generic Data Exemption Statement (EPA Form 8580-3),
          if applicable, or the "FIFRA Section 3(c)(2)(B)
          Summary Sheet"  (EPA Form 8580-1), with appropriate
          attachments.

     b.   Confidential Statement of Formula (EPA Form

                           TGUIDE-1

                       GUIDE TO TABLES                     	

     Tables A, B, and C 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.

     Table B contains product-specific data requirements that
     apply only to a manufacturing use product.

     Table C contains product-specific data requirements that
     apply only to an end use product.

     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 153.
The 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 laoeled
     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 153.  The following
letter designations are used for the given use patterns:

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

Any other designations will be  defined in a footnote to  the table.
                            - 30  -

-------
                           TGUIDE-2

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

     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 terra 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.

     NO - 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 inits 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
columnindicates 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 timefraraes 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.

     I/  Data depicting the uptake,  distribution, and metabolism  of  ring-labeled  [l^cjpropazine in sorghum following
        preplant  application at a rate sufficiently high  to permit  complete  l^C-residue  identification must  be submitted.
     2/  Representative samples from the above-described tests must  also be analyzed  using accepted enforcement
        methods to ascertain that these methods will determine all  possible  metabolites  of concern.

                                          GENERIC  DATA REQUIREMENTS FOR PROPAZINE
 V Metabolism studies utilizing ruminants and poultry must be submitted.   Animals must be dosed for  at  least  3  days
    with ring-labeled [14C]propazine at  a  concentration that will  result  in sufficient residues for characterization  in
    the tissues, milk, and eggs.  Studies  must elucidate the identities and quantities of all metabolites in milk,  eggs,
    liver,  kidney, muscle, and fat.   Milk  and  eggs  must be collected twice  daily during the dosing period.   Animals must
    be sacrificed within 24 hours of the final dose.
 4/ 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 plants
    or animals.
 5/ The storage intervals and conditions for all  samples used to support  all tolerances for residues  of
    propazine in or on sorghum must be  submitted.   These data must be accompanied by data depicting the  decline  of
    residues during the interval and under the conditions specified.  In  laboratory tests using fortified samples,
    the pure active ingredient and pure  metabolites (if necessary) must be  used.  However, if field-weathered
    samples are used, the test substance must  be  a  typical end-use product.
 6/ 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 specified.   In  laboratory tests using fortified samples, the pure active  ingredient
    and pure metabolites (if necessary)  must be used.   However, if field-weathered samples are used,  the test
    substance must be a typical end-use  product.
 7/ If registrant seeks a crop group tolerance, use directions must be proposed and appropriate supporting data
    must be submitted for three additional representative commodities (corn, rice, and wheat)
 8/ Data depicting propazine residues of concern  in syrup processed from  sweet sorghum and in milled  products
    (flour and starch) and grain dust processed from  grain sorghum bearing  measurable, weathered residues must be
    submitted.  If residues concentrate in any of these processed commodities, appropriate food/feed  additive  regulations
    must be proposed.
 9/ If registrant seeks a crop group tolerance, use directions must be proposed and appropriate supporting residue
    data submitted for corn and wheat.
10/ 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 meat,
    milk, poultry, and eggs will be determined.

       I/ There is no evidence, based on propazine's chemical structure, to suggest that propazine is a neurotoxic compound.
       _2/ Subchronic oral studies in the rodent are unnecessary since a rat chronic study is available to support permanent
          tolerances.  A separate subchronic oral study in nonrodents is unnecessary since a chronic study is requirecj.
       V This study is not needed because the existing acceptable end uses should not result in repeated human skin qontact
          for extended periods.                                                           •                            j
       4/ This study is not required because the existing end uses should not result in repeated inhalation exposure.
       5/ An acute neurotoxicity study is not required on propazine;  therefore,  this study is not required.

I/ Based on toxicity data and the use patterns, this study is not required.
2/ Based on use patterns, this study is not required.
3/ This study is not required due to the low estimated environmental concentration (EEC) (0.039 ppm) and the slight
   toxicity to freshwater fish (LC50 > 10 ppm).
V Required to support use on sorghum because of potential exposure of estuarine/marine environments through
   runoff and drift.
5/ Required to support registration of an end-use product when the product is expected to be transported to water
   from the intended use site and it is expected to be highly persistent in this environment.
6/ Required to support the sorghum use.  Propazine is primarily used on sorghum in Texas and Kansas.
   Over 300,000 acres of sorghum are grown in coastal counties in Texas alone.  In addition, propazine is
   expected to be highly persistent in the aquatic environment.
7/ Based on the toxicity data and the low EEC, these studies are not required.

   materials, chemical reactions (intended and side) in the manufacturing process, and any contamination during and
   after production must be submitted.  This discussion must also address the possible formation of nitrosamines.
4/ Five or more representative samples must be analyzed for the amount of active ingredient and each impurity for
   which a certified limit is required.  Complete validation data (accuracy, precision) must be submitted for each
   analytical method used.  All nitrosoamines must be identified and quantified in six samples of each product;
   two samples of each must be analyzed shortly after production, 3 months after production, and 6 months after
   production.  A method sensitive to 1 ppm of N-nitroso contaminants must be used.  An upper limit must be
   provided (and certified) for all nitrosoamines found.  Certifications should be submitted on EPA Form 8570-4
   (Rev. 2-85).

                          SUMMARY-1

                        LABEL CONTENTS

     40 CFR 156.10 requires that certain specific  Labeling
statements appear at certain locations on the label.   This
is referred to as format labeling.  Specific label items  listed
below are keyed to the table at the end of this  Appendix.

     Item 1.  PRODUCT NAME - The name, brand or  trademark is
required to be located on the front panel, preferably centered
in the upper part of the panel.  The name of a product will
not be accepted if it is false or misleading.

     Item 2.  COMPANY NAME AND ADDRESS - The name  and address
of the registrant or distributor is required on  the label.
The name and address should preferably be located  at the
bottom of the front panel or at the end of the label text.

     Item 3.  NET CONTENTS - A net contents statement is
required on all labels or on the container of the  pesticide.
The preferred location is the bottom of the front  panel
immediately above the company name and address,  or at the end
of the label text.  The net contents must be expressed in the
largest suitable unit, e.g., "1 pound 10 ounces" rather than
"26 ounces." In addition to English units, net contents may
be expressed in metric units.  [40 CFR 156.10(d)]

     Item 4.  EPA REGISTRATION NUMBER - The registration
number assigned to the pesticide product must appear on the
label, preceded by the phrase "EPA Registration No.," or "EPA
Reg. No."  The registration number must be set in  type of a
size and style similar to other print on that part of the
label on which it appears and must run parallel  to it.  The
registration number and the required  identifying phrase must
not appear in such a manner as to suggest or imply recommendation
or endorsement of the product by the Agency.
[40 CFR 156.10(e)]

    Item 5.  EPA ESTABLISHMENT NUMBER - The EPA establishment
number, preceded by the phrase "EPA Est." is the final estab-
lishment at which the product was produced, and may appear
in any suitable location on the label or immediate container.
It must also appear on the wrapper or outside container of
the package if the EPA establishment number on the immediate
container cannot be clearly read through such wrapper or container.
[40 CFR 156.10(f)J

    Item 6A. INGREDIENTS STATEMENT - An  ingredients statement
is required on the front panel.  The  ingredients statement must
contain the name and percentage by weight of each active ingredient
and the total percentage by weight of all inert ingredients.
The preferred location is immediately below  the product name.
The ingredients statement must run parallel with, and be clearly
distinguished from, other text on the panel.  It must not be
placed in the body of other text.  [40 CFR  156.10(g)]

    over 30                   18 point             12 point

    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 156.10(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 156.10(h)(1)(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 156.10(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 156.10(h)(1)(iii)]

    Item 7E.  REFERRAL STATEMENT - The statement "See Side

[40 CFR 162.56(h)(l)(iii)J

    Item 8.  SIDE/BACK PANEL PRECAUTIONARY LABELING  - The
precautionary statements listed below must appear together
on the label under the heading "PRECAUTIONARY STATEMENTS."
The preferred location is at the top of  the side or  back
panel preceding the directions for use,  and it  is preferred
that these statements be surrounded by a block outline.   Each
of the three hazard warning statements must be headed by  the
appropriate hazard title.  [40 CFR 156.10(h)(2)].
                               - 56 -

-------
                          SUMMARY-3

    Item 8A.  HAZARD TO HUMANS AND DOMESTIC ANIMALS  - Where a
hazard exists to humans or domestic animals, precautionary
statements are required indicating the particular hazard,  the
route(s) of exposure and the precautions to be taken to avoid
accident, injury or damage.  [40 CFR 156.10(h)(2)(i)]

    Item 8B.  ENVIRONMENTAL HAZARD - Where a hazard  exists to
non-target organisms excluding humans and  domestic animals,
precautionary statements are required stating the nature of
the hazard and the appropriate precautions to avoid  potential
accident, injury, or damage.  [40 CFR 156.10(h)(2)(ii)]

    Item 8C.  PHYSICAL OR CHEMICAL HAZARD  - FLAMMABILITY
Precautionary statements relating to flammability of a product
are required to appear on the label if it  meets  the  criteria
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 flaramability  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
for 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, you must submit any information and
rationale with your application for reregistration.    During
the Agency's review of your application, your proposed  classi-
fication determination will be evaluated  in accordance with
the provisions of Part 152, Subpart I.  You will  be notified
of the Agency's classification decision.
                               - 57 -

-------
                          SUMI1ARY-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 156.10(h)(1)(iv)

         b.  Directly below this statement on the front  panel,
     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.
                                -  58  -

-------
                          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 terras 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 unreasonable adverse effects on the environment.
[40 CFR 156.10]


                     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.
                               - 59 -

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 wrapper or outside  container
through which the label 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 isin 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 § 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;
                                - 64 -

-------
   (ix)   Claims as  to  the safety of the pesticide or its ingredients,
 including  statements  such as "safe,^1 "nonpoisonous," "noninjurious,"
 "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)(n)  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:
   (i)  Is  false or misleading, or
   (ii)   Has not been approved by the Administrator through
 registration or supplemental registration as an additional name
 pursuant to S 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°F (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."
                                 -  65  -

-------
   (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.",  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 arsenic.
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.


                                 - 66 -

-------
   (3)   Names  to be used  in ingredient statement.  The name
 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  statedin 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:

-------
   (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 hazard 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 distribution, marketing, storage or use is
 demonstrated by the applicant to be extremely remote, 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—(A)  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
 reasonable variations in the placement of the statement of
 practical treatment is some reference such as "See statement of
 practical treatment on back panel" appears on the front panel
 near the word "Poison" and the skull and crossbones.
   (B)   Other toxicity categories.  The statement of practical
 treatment is not required on the front panel except as described
 in paragraph (h)(1)(iii)(A) of this section.  The applicant may,
 however, include such a front panel statement at his option.
 Statements of practical treatment are, however, required elsewhere
on the label in accord with paragraph (h)(2) of this section  if
 they do not appear on the front panel.
   (iv)   Placement and prominence.  All the required front panel
warning statements shall be grouped together on the label, and
shall  appear with sufficient prominence relative to other front
panel  text and graphic material to make them unlikely  to be over-
looked under customary conditions of purchase and use.  The
following table shows the minimum type size requirements for  the
front  panel warning statements on various sizes of labels:

    (2)   Other required  warnings and  precautionary  statements.   The
 warnings  and precautionary statements as  required  below  shall  appear
 together  on the  label  under  the general heading  "Precautionary
 Statements" and  under  appropriate subheadings of  "Hazard to  Humans
 and  Domestic Animals/" "Environmental Hazard" and  "Physical  or
 Chemical  Hazard."
    (i)   Hazard  to humans and  domestic animals.   (A)  Where a  hazard
 exists to humans or domestic animals, precautionary statements
 are  required indicating the  particular hazard,  the route(s)  of
 exposure  and the precautions to be  taken  to avoid accident,  injury
 or damage.   The  precautionary paragraph shall be  immediately
 preceded  by the  appropriate  hazard  signal word.

 damage.   Examples  of  the hazard statements and the circumstances
 under which  they are  required follow:
   (A)   If  a  pesticide  intended for outdoor use contains an active
 ingredient with a  mammalian acute oral LD$Q of 100 or less, the
 statement  "This Pesticide is Toxic to Wildlife" is required.
   (B)   If  a  pesticide  intended for outdoor use contains an active
 ingredient with a  fish acute LCe,Q of 1 ppm or less, the statement
 "This Pesticide is Toxic to Fish" is required.
   (C)   If  a  pesticide  intended for outdoor use contains an active
 ingredient with an avian acute oral LD^Q of 100 mg/kg or less, or
 a  subacute dietary LC$Q of 500 ppm or less, the statement  "This
 Pesticide  is Toxic to Wildlife" is required.
   (D)   If  either accident history or field studies demonstrate
 that use of  the pesticide may result in fatality to birds, fish
 or mammals,  the statement "This pesticide  is extremely toxic to
 wildlife  (fish)" is required.
   (E)   For uses involving foliar application to agricultural
 crops,  forests, or shade trees, or for mosquito abatement
 treatments,  pesticides toxic to pollinating insects must bear
 appropriate  label cautions.
   (F)   For all outdoor uses other than aquatic applications the
 label must bear the caution "Keep out of lakes, ponds or streams.
 Do not  contaminate water by cleaning of equipment  or disposal  of
wastes."
   (iii)   Physical or chemical hazards.  Warning statements on  the
 flammability or explosive characteristics of the pesticide are
 required as  follows:
Flash point

   (i)  Directions for Use—(1)   General requirements—(i)   Adequacy
and  clarity of directions.  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 unreasonable
adverse effects on the environment.
   (ii)  Placement of directions for use.  Directions may  appear
on any portion of the label provided that they are conspicuous
enough to be easily read by the user of the pesticide product.
Directions for use may appear on printed or graphic matter which
accompanies the pesticide provided that:
   (A)  If required by the Agency, such printed or graphic matter
is securely attached to each package of the pesticide,  or placed
within the outside wrapper or bag;
   (B)  The label bears a reference to the directions for  use  in
accompanying leaflets or circulars, such as "See directions in
the enclosed circular."  and
   (C)  The Administrator determines that it is not necessary  for
such directions to appear on the label.
   (i i i)  Exceptions to requirement for direction for use—(A)
Detailed directions for use may be omitted from labeling  of
pesticides which are intended for use only by manufacturers of
products other than pesticide products  in their regular manu-
facturing processes, provided that:
   Q)  The label clearly shows that the product is  intended for
use only in manufacturing processes and specifies  the type(s) of
products involved.
   (2^)  Adequate information such as technical data  sheets or
bulletins, is available to the trade specifying the  type of
product involved and its proper use in  manufacturing processes;
   O)  The product will not come  into  the hands of  the general
public except after incorporation  into  finished products; and
   M)  The Administrator determines that  such directions are not
necessary to prevent unreasonable adverse effects  on man or the
env ironment.
   (B)  Detailed directions for use may  be omitted  from the labeling
of pesticide products for which sale  is limited  to physicians,
veterinarians, or druggists, provided  that:
   (JL_)  The label clearly states that  the  product  is for  use only
by physicians or veterinarians;
   (2_)  The Administrator determines that' such  directions  are  not
necessary to prevent unreasonable  adverse effects on man  or  the
environment; and
   (_3)  The product is also a drug  and  regulated  under  the  provisions
of the Federal Food, Drug and Cosmetic Act.
   (C)  Detailed directions for use  may be omitted from the labeling
of pesticide products which are  intended for use only  by formulators
in preparing pesticides for sale  to the public,  provided that:
   (!_)  There is information readily available to the formulators
on the composition, toxicity, methods of use,  applicable restriction;
or limitations, and effectiveness of  the product for pesticide
purposes;

  (j)  Statement of Use Classification.   By October 22, 1976, all
pesticide products must bear  on their  labels a statement of use
classification as described in  paragraphs (j)(l) and (2) of this
section.   Any pesticide product for which some uses are classified
for general use and others for  restricted use shall be separately
labeled according to the labeling standards set  forth in this
subsection, and shall be marketed as separate products with
different registration numbers, one bearing directions only for
general use(s) and the other  bearing directions  for restricted
use(s) except that, if a product has both restricted use(s) and
general use(s), both of these uses  may appear on a product  labeled
for restricted use.  Such products  shall  be subject to the
provisions of S 162 .10(j)(2).
  (1)  General Use Classification.   Pesticide products bearing
directions for use(s) classified general  shall be  labeled with
the exact words "General classification"  immediately below  the
heading "Directions for Use."  And reference  to  the general
classification that suggests  or implies that  the general  utility
of the pesticide extends beyond those purposes  and  uses  contained
in the Directions for Use will be considered  a  false  or  misleading
statement under the statutory definitions of  misbranding.
  (2)  Restricted Use Classification.  Pesticide products  bearing
direction for use(s) classified restricted shall bear  statements
of restricted use classification on the  front panel  as  described
below:
  (i)  Front panel statement  of restricted use  classification.
(A)  At the top of the front  panel of the label, set  in type of
the same minimum sizes as required for human hazard signal words
(see table in S 162.10(h)(1)(iv)) , and appearing with sufficient
prominence relative to other  text and graphic material on the
front panel to make it unlikely to be overlooked under customary
conditions of purchase and use, the statement "Restricted use
Pesticide" shall appear.
  (B)  Directly below  this statement  on  the front panel, a summary
statement of the terms of restriction  imposed as a precondition
to registration shall  appear.   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."   If, however, other
regulatory restrictions  are  imposed,  the Administrator will  define
the appropriate wording  for  the terms of restriction by regulation

             STORAGE INSTRUCTIONS FOR PESTICIDES

Heading:

All products are required to bear specific label  instructions
about storage and disposal.   Storage and  disposal  instructions
must be grouped together in  the directions for use portion  of
the label under the heading  STORAGE AND DISPOSAL.   Products
intended solely for domestic use need not include  the  heading
"STORAGE AND DISPOSAL."

Storage Instructions;

All product labels are required to have appropriate storage
instructions.  Specific storage instructions are not prescribed.
Each registrant must develop his own storage instructions,
considering, when applicable, the following factors:

1.  Conditions of storage that might alter the composition  or
    usefulness of the  pesticide.  Examples could be temperature
    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.

4.  Instructions on what to  do if the container is damaged  in
    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.

III.  BIBLIOGRAPHY APPENDICES

-------
                        BIBGUIDE-1

          GUIDE TO USE OF THIS BIBLIOGRAPHY


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.

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

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.

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.

                    BIBGUIDE-2

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

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
or estimate the date of the document.

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.

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.

EPA Product Registration Number:.
Registrant's Name and Address:
As an authorized representative of the registrant of the product identified above,  I
certify that:

(1)  I have read and am familiar with the terms of the Notice from EPA dated
	 concerning a requirement for submission of "generic" data on the active
ingredient	 named under FIFRA Section 3(c) (2) (B).

(2)  My firm requests that EPA not suspend the registration of our product, despite
our lack of intent to submit the generic data in question, on the grounds that the
product contains the active ingredient solely as the result of the incorporation into
the product of another product which contains that active ingredient, which is
registered under FIFRA Section 3, and which is purchased by us from another producer.

(3)  An accurate Confidential Statement of Formula (CSF) for the above-identified
product is attached to this statement.  That formula statement indicates, by company
name, registration number, and product name, the source of the subject active
ingredient in my firm's product, or

The CSF dated	 on file with EPA is complete, current and accurate and
contains the information requested on the current CSF Form 8570-4.  The registered
source(s) of the above named active ingredient in my product(s) is/are	 and
their registration number(s) is/are	.

My firm will apply for an amendment to the registration prior to changing the source
of the active ingredient in our product.

(4)  I understand, and agree on behalf of my firm, that if at any time any portion of
this Statement is no longer true, or if my firm fails to comply with the undertakings
made in this Statement, my firm's product's registration may be suspended under FIFRA
Section 3(c)(2)(B).

(5)  I further understand that if my firm is granted a generic data exemption for the
product, my firm relies on the efforts of other persons to provide the Agency with the
required generic data.  If the registrant(s) who have committed to generate and submit
the required data fail to take appropriate steps to meet requirements or are no longer
in compliance with this Notice's data requirements, the Agency will consider that both
they and my firm are not in compliance and will normally initiate proceedings to
suspend the registrations of my firm's product(s) and their product(s), unless my firm
commits to submit and submits the required data in the specified time frame.  I
understand that, in such cases, the Agency generally will not grant a time extension
for submitting the data.
