                       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 Uses may be
obtained from the National Technical Information Service
(NTIS), Attn:  Order Desk, 5285 Port Royal Road, Springfield,
VA 22161. Telephone  (703) 487-4650.

-------
     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

-------
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.

             II.  CHEMICALS COVERED BY THIS STANDARD
A.  DESCRIPTION OF CHEMICALS

    This Standard covers 4-(2,4-dichlorophenoxy)butyric acid
(2,4-DB) and its inorganic salt, amine and esters.

    The acid is not formulated as an end-use product; instead the
typical end-use product, as applied, is a formulation of a sodium
salt, dimethylamine, or ester (2-butoxyethyl or isooctyl) of the
parent compound.  With these formulations, the esters or amine may
greatly influence the physical characteristics, biological activity
and environmental fate of the chemical.  The Agency has little or
no data to evaluate the behavior of these compounds in the environ-
ment.  Therefore, the data requirements in this Standard address
not only the acid and its inorganic salt but also the amine salt
and esters.

C•  BACKGROUND

    On December 3,  1986,  the Agency  issued a preliminary
notification of Special Review to registrants of 2,^1-DB and
2,4-DP (a similar notice was Issued to 2,4-D registrants on
September 22,  1986).*  This notice was based on epidemiological
evidence thab indicated an association between farm herbicide ase
of phenoxy herbicides (including 2,4-D)  and cancer (non-Hodgkin's
lymphoraa).   2,4-DB and 2,4-DP were considered for review at the
same time since these compounds  are  structurally related to
2,4-D.
*The Special Review process, described in MO CFR Part 154, is the
 mechanism by which the Agency determines whether a pesticide poses
 unresonable adverse effects to man or the environment.   In Special
 Review, the Agency weighs  the risk of pesticide use against the
 benefits of use.   Documents are made available during the process
 to permit public  participation in EPA's  deliberations prior to
 any final determination of regulatory action.

-------
    The Agency has subsequently issued a proposed decision
not to intiate a special review for 2,4-D, 2,4-DB and 2,4-DP
(53 FR 9590, March 23, 1988).  In this document the Agency
proposed that special review is not appropriate at this time
for any of the compounds and that a decision regarding whether
to group 2,4-D, 2,4-DB and 2,4-DP in future review activities
will be made as additional metabolic and toxicologic data are
developed.  Final action has not been taken on this  proposal.

    As part of the Agency's strategy on dioxins,  the Agency
issued a Data Call-in in June 1987 requiring registrants  to
analyze their 2,4-DB products for certin halogenated
dibenzo-p-dioxin or dibenzofuran (HDD and HDF) contaminants.
This notice was issued based on the Agency's assumption
that,  because of the chemical structure, class and certain
manufacturing and processing conditions, 2,4-DB products
could be contaminated with HDDs or HDFs.  Draft protocols
for analyzing the pesticide have been submitted.   The
Agency is  evaluating the proposed methods to determine
whether they meet the requirements specified in the  Data
Call-in Notice.

-------
                      III.   AGENCY ASSESSMENT
 A.   SUMMARY

     The Agency has reviewed all  data,  submitted to  support
 registration  of 2,4-DB  products,  available  through  November  1987-
 Based on the  review of  these data,  EPA has  reached  the
 conclusions set forth in  this  Standard.   A  summary  of those
 conclusions follows.  Additional  discussion is  contained  in  the
 remainder  of  this  Chapter.

     1.   When  2,4-DB is  formulated as  an ester or amine, the
 physical characteristics, biological  activity and fate in the
 environment will be affected.  EPA  has little or no data  to
 evaluate the  changed effects resulting from the  conversion to
 an  ester or an amine.   Therefore, the  data  requirements imposed
 by  this  Standard include  testing  for  the  2,4-D3  esters and anine
 as  well  as  the acid.

     2.   The Agency  has  concluded  that  existing  data are inadequate
 to  assess the  carcinogenic  potential  of  2,4-DB.   Although under
 conditions  of  the  study,  2,4-DB was not  oncogenic in the rat, in
 a mouse oncogenic  study there was a weak  but possible dose-
 relationship  involving  hepatocellular  carcinomas  in males.
 A new mouse oncogenicity  st.udy or historical control data -on
 certain  tumor  incidence in  the strain  of  mice utilized at the
 testing facility are required before  the  significance of these
 results  can be determined.

     3.  Concern about possible neurotoxic effects for the family
 of  2,4-D compounds  (2,4-D,  2,4-DB, and 2,4-DP) has  prompted the
 requirement for a special neurotoxicity study on 2,4-D.   A special
 study is not required for 2,4-DB at  this time.  Pending the outcome
 of  the 2,4-D s.tudy, however, precautionary labeling  requiring
 gloves is required for all end-use products.

     4.  Concern about possible groundwater contamination exists
 for the family of 2,4-D compounds (2,4-D, 2,4-DB, and 2,4-DP).
 Additional  data and a label warning  are required.

     As a result of this  review, the  Agency has identified  data
 necessary to further evaluate environmental and human risks
 associated with the use  of 2,4-DB.  These data must  be  submitted
 in order to maintain registration of products or register  new
products containing 2,4-DB.   These data are listed in the  Data
Tables contained in Appendix I.
                                  7

-------
 B.   TOXICOLOGICAL _AS_SESSMENT

     This  section discusses  data available  to the Agency for
 2,4-DB acid and 2,4-DB[x] compounds where  [x] refers to the
 substituted dimethylamine salt, 2-butoxyethanol ester, butyl
 ester, or isooctyl ester.

     1.  Acute _Toxicity__Studies

        Acceptable acute oral, acute dermal, primary eye irritation,
 and  primary skin irritation studies indicate that 2,4-DB acid is
 mildly toxic  (Category III and IV).  Acute inhalation and skin
 sensitization testings are data gaps.  No  data are available for
 the  2,4-DB[x] compounds.

     2.  Subchrpnic Toxicity Studies

        An acceptable 90-day study in dogs fed 0, 2.5, 8,  25, or
 80 mg/kg/day of 2,4-DB acid showed mortality, body weight  depression,
 and  histopathological findings at 25 and 80 mg/kg/day.  The lowest-
 observed effect level (LOEL) was 25 mg/kg/day;  the no-observed-
 effect level (NOEL) was 8 mg/kg/day.

        In a rat study, decreases in body weight were seen.   The
 LOEL was 1000 ppm and NOEL 316 ppm.  Although this sbudy does not
 meet Agency requirements, a new study is not required because an
 acceptable chronic feeding study is available for 2,4-DB acid.

        No data are available for 2,4-DB[x] compounds.  Data  are
 required for the amine and esters.

    3.  Ch rqn i c To x i c i ty/One ogen i ci t y Studies

      •  An acceptable chronic feeding study in  CD rats fed 0, 3, 30,
 or 90 mg/kg/day of 2,4-DB acid showed decreased mean body  weight
 gains, changes in blood chemistry, hematology parameters,  and
 significantly lower heart weights  than  control  at higher dose levels.
 The LOEL for systemic effects was 30 mg/kg/day  and the NOEL  was 3
mg/kg/day.  Under  conditions study 2,4-DB acid  was  not  oncogenic in
 the rat.

        In an oncogenlcity study in CD-I mice fed 0,  3.75,  37.5,
and 112.5  mg/kg/day of 2,4-DB acid there was  a  no conclusive
 evidence of oncogenicity.  However, there was a weak, but  possibly
 dose related increased incidence of hepatocellular  carcinomas
 in males.
                               8

-------
         This  mouse study  was  deficient  because  historical  control
 data  on  certain  tumor  incidences  (bronchiolar adenomas and carcinomas,
 as  well  as  hepatocellular carcinomas) from males  of  Grl:CD®l(OR)(BR)
 mice  utilized at  the testing  facility were not  submitted.   Unless
 the data are  submitted, the study must  be repeated.

         Additionally,  justification has to be made that the highest
 dose  tested (112.5  mg/kg/day)  is a maxinum tolerated dose  (MTD)  (or
 is  close enough  to  a MTD)  in  female mice of this  strain.

    4.   Terato logy _Stu_dle s

         In  a  mouse  study  with 2,4-DB acid the maternal toxicity
 and fetotoxic NOEL  was 60  mg/kg/day, but this study  is inadequate
 because  it  utilized two dose  levels rather than the  required  three
 treatment levels.

         In  a  rabbit study  with 2,4-DB, acid the  maternal toxicity
 NOEL  and fetotoxic  NOEL was 12 mg/kg/day, but this study is
 inadequate  because  it  utilized two dose levels  rather than the
 three required and  there  was  an excessive incidence  of nonpregnant
 females.

         New teratology studies are required for 2,4-D8 acid.
 No  data  are available  for  the  2,4-DB[x] compounds, and
 teratology  studies  are required for each ester  and amine.

    5.   Reproduction Studies

         In  an acceptable  two-generation reproduction study  in
 CD  rats  fed 0, 3, 15,  and  75 mg/kg/day of 2,4-DB  acid, the
 reproductive  NOEL was  15 mg/kg/day.  At 75 mg/kg/day ovarian weight
 was significantly less in  treated dams than in  controls, mean birth
 weights  were  lower, fewer  total pups were born  per litter,  greater
 number of pups were dead at birth, and extremely  high pup mortality
 occurred during  the lactation  period.

    6.   Mu^agenicity Studies

         In  an Ames  study,  2,4-DB acid tested negative with  and
 without  metabolic activation.  A Chinese Hamster  Ovary HGPRT
 assay suggests that with activation 2,4-DB acid is a weak mutagen
 Immediately below doses causing high levels of  cytotoxicity.  No
 evidence of rnutagenic activity in this assay was  observed without
 activation, but this part of the assay has been classified as
 unacceptable  because an insufficient level of cytotoxicity was reached.
 In Chinese Hamster Ovary cells, 2,4-DB acid at 750 and 1000 ug/ml
 without  activation caused a significant increase  in chromosomal
aberrations with 17.25-hour exposure,  but  there was no increase
In the presence of activation with a 2-hour  exposure.  In  an
unscheduled DNA synthesis  with rat  hepatocytes,  there was  no evidence
of induction.

-------
    7.   Metabolism Studies

        No data are available on the metabolism of 2,4-DB acid or
2,4-DB[x] compounds.   Data are required for the acid,  amine  and
ester.

    8.   Ne u r o to x 1 c i t y_S t u di e s

        Several instances of accidental human poisoning with
2,4-D,  resulting in severe neurotoxicity,  have been reported.
Since 2,4-DB is structurally related to 2,4-D, this concern  exists
for 2,4-DB compounds  as well.  No acceptable studies for 2,4-D3
are available.  A neurotoxicity study has  been required 2,4-D.
If the  2,4-D study shows neurotoxlc effects, studies may be
required using 2,4-DB.

C .  OTHER SCIENCE FINDINGS

    1.   Environmental Pate

        The Agency has no acceptable data  pertinent to the fate of
2,4-DB acid or 2,4-DB[x] compounds.

        a.  Groundwater

            Available data for 2,4-D suggest that chemicals  in
the 2,4-D family of compounds (2,4-D, 2,4-DB, and 2,4-DP) has  the
potential to contaminate groundwater.  The Agency is requiring
data to further assess the mobility of these compounds.

        b.  Reentry

            Based on data available to the Agency, 2,4-DB
products do not meet  the toxiclty criteria specified in
40 CFR 158 for reentry data and the time of application •
to weeds coupled with rapid dissipation, limits the exposure of
workers reentering the area of application.  Reentry data are
not being required at this time.

        Available  data are  insufficient to completely assess  the
ecological effects of 2,4-DB acid and 2,4-DB[x] compounds to
wildlife and aquatic organisms.  The following preliminary
conclusions can be made, however, based on available data,
(NOTE: all figures are 1,050 values):

        a.  Avian Effects

            No acceptable acute oral data are available on day
2,4-DB compound.  The Agency has acceptable dietary studies on
2,4-DB acid and 2,4-DB sodium salt  to characterLae  fch'^e
compounds as practically nontoxic (> 5000 ppra, respectively)  to
waterfowl and upland game birds on  a subacute basis.  There are
no avian subacute oral data available for the 2,4-DB[x] compounds,
and these data are required.

        b.  Aquatic Organism Effects

            Acceptable data on 2,4-DB acid and 2,4-DB sodium  salt
indicates these compounds are moderately to slightly toxic to
freshwater fish (fathead minnow 18  ppm, bluegill sunfish 7.5
and 17 ppm, rainbow trout 2.0 and 14 ppn, depending on test
conditions).  There are no acceptable data for acute toxicity to
freshwater invertebrates on any 2,4-DB compound.  There are no data
available on acute toxicity to freshwater fish for the 2,4-D3[x]
compounds.

        c.  Nontarg et_I n s e_c_t _Ef feet s

            Acceptable data on 2,4-DB dimethylamine indicates a
low toxicity to bees.   Data from a honey bee acute contact study
are required for 2,4-DB isooctyl and 2-butoxyethanol esters.

        d-  Nqiit_ar_get___Plarit Effects

            There are no data available to evaluate phytotoxicifcy
of 2,4-DB compounds to nontarget plants.  Since 2,4-DB is a
broadleaf herbicide,  there is a potential hazard to nontarget
plants from existing uses.

        e.  Endangered Species
            Because of limited environmental fate and ecological
effects data, hazard assessments for endangered species cannot
be completed at this time.  When additional data are received,
the Agency will determine whether consultation with the Office
of Endangered Species (OES), U.S. Pish and Wildlife Service is
appropriate.
                                  1 1

-------
                Chem i sjt rjr
        The Agency has noted that 2,4-DB may be contaminated
with tetra- through heptahalognated dibenzo-p-dioxins or
dibenzofurans, or N-nitrosamines.  Certain polyhalognated
dibenzo-p-dioxin or dibenzofuran congeners have found to
be mutagenic, oncogenic, teratogenic and to cause reproductive
toxicity.  Nitrosamines have been found to be oncogenic.
Analytical data to identify and quantify tetra- through
heptachlorrinated dibenzo-p-dioxin or dibenzofuran contaminants
were required in a Data Call-in Notice issued in June 1987.
Analytic data to identify and quantify N-nitrosamine are being
required, as specified in the data tables.

D •   TOLE RAN C E_AS S E S S M E NT

    Tolerances of 0.2 ppm have been established for residues of
2,4-DB and its metabolite 2,4-D in or on alfalfa, clover, mint
hay, peanuts, soybeans, soybeans hay, and birdsfoot trefoil (40
CFR 180.331).  No Mexican tolerance or Codex MRL exists for,
residues of 2,4-DB.  Therefore, no compatibility question exists
with respect with Codex MRL.

    EPA has evaluated the residue and toxicology data supporting
these tolerances.  The following issues were considered during
this evaluation:

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

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

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

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

    The regulatory results of the Agency's review are set out in
the Regulatory Positions and Rationale section.

    1 •  Residue .Data

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

        a.  Data on the nature of the residues in both plants
and animals, including identification of major metabolites and
degradates of 2,4-DB.  The nature of the residue is not adequately
understood.
                                  12

-------
        b.  Analytical methodology for determining the levels
of residues of 2,4-DB in plants and animals.  The nature of the
residue in plants and animals has not been adequately described.
Therefore, the adequacy of available analytical methods cannot be
determined.

        c.  Storage stability data.  These data demonstrate that
residues of 2,4-DB and 2,4-D are relatively stable in soybeans,
peanuts, and alfalfa for up to 1 year when stored at -20 °C.
Additional data are required.

        d.  Data on the magnitude and levels of residues of
2,4-DB in individual raw agricultural commodities.  Data are
not adequate to support the established tolerances.

    2.  Toxicology Data

        The toxicology data for 2,4-DB are insufficient to
determine an Acceptable Daily Intake (ADI).  However, a
Provisional Acceptable Daily Intake (PADI) has been
calculated based on a rat chronic feeding study with a
NOEL of 3 mg/kg/day and using an uncertainty factor of
300.  The PADI with a 300-fold safety factor is calculated
to be 0.01 mg/kg/day.  A comparison of the published
tolerances to the PADI was conducted using the Tolerance
Assessment System, Routine Chronic Analysis.  Based on the
analysis a Theortical Maximum Residue Contribution (TMRC)
for the U.S. population was calculated to be 0.000083
mg/kg/day, which utilizes 0.83 percent of the PADI.  Using
the TMRC provides a conservative estimate since it does
not consider the effect of processing on  residue levels in
the raw agricultural commodity, that actual residue levels
may be lower than the established tolerance, and that less
than 100 percent of the crop is treated.

              IV.   REGULATORY_POSITION_AND_RATIONALE


A •   REGUL^ATORY_Pg S FT ION S _AN D_RAT I ONALE S

    Based on review and evaluation of available data on 2,4-DB,
the Agency has made the following determinations.  Where label
revisions are imposed, specific language is set forth in the
Labeling portion of this section.

     1.  The Agency will not place 2,4-DB in Special Review at
this time.

         Rati_qnal_e.  In December 1986, the Agency issued a
preliminary notification of special review to the registrants
of 2,4-DB and 2,4-DP, based on epidemiologic evidencce
available at that time (a similar notice had been issued to
2,4-D registrants in September 1986).  After additional
evaluation of this evidence the Agency subsequently concluded
that these data were inadequate to assess oncogenic potential
for the 2,4-D family of compounds (2,4-D, 2.4-DB and 2,4-DP).
Therefore, in March 1988, EPA proposed not to initiate a
special review of any of the chemicals at this time.

The Agency's concerns regarding toxicological effects have.not
been fully resolved.  Additional epidemiological studies are
expected to be completed soon and additional laboratory studies
are required by this Standard.  As these data become available,
the Agency will further evaluate potential risks from these
compounds and could initiate a special review at a later time
and/or consider additional regulatory action, if appropriate.
A decision whether to group 2,4-D, 2,4-DB and 2,4-DP in future
review activities will be made as additional metabolic and
toxicologic data are developed.

     2.  The Agency will not restrict the use of 2>4-DB products
to certified applicators.

         Rationale.  Based on available data, 2,4-DB products
have not met or exceeded any criteria specified in 40 CFR 152.170
which would indicate a need to restrict the use of 2,4-DB to
certified applicators only.

     3.  The Agency will require data on the amines and esters
of 2,4-DB as well as the acid.

         Rationale.  When 2,4-DB is formulated as an amine or
ester, the biological activity and fate in the environment will
be affected.  Since the Agency has little or no data to evaluate
the effects of the  [x] moiety, data are needed on each [x] compound
to evaluate these characteristics for the particular amine or
ester form.
                            14

-------
     4.  The Agency will not establish tolerances for significant
new food uses of 2,4-DB.

         Rat_i_qn_a^e.  The current residue chemistry and toxicology
data are not sufficient to assess existing and pending tolerances.
Therefore, the Agency will not consider any significant new food
uses until data are available to resolve these issues.

     5.  The Agency will propose the following technical changes
in listing of 2,4-DB tolerances (i) the commodity entry "alfalfa"
will be amended to "alfalfa forage" and "alfalfa hay"; (ii) the
commodity entry "birdsfoot trefoil" will be amended to "birdsfoot
trefoil forage" and "birdsfoot trefoil hay"; and (iii) the
commodity entry "clover" will be amended to "clover forage" and
"clover hay."

         Rati^qnal^e.  These technical changes are required because the
addition of "forage" and "hay" clarifies the tolerance statements.

     6.  The Agency will revise the,tolerance statement to
include 2,4-DB sodium salt, 2,4-DB dimethylamine salt, 2,4-DB
2-butoxyethanol ester, and 2,4-DB isooctyl ester; if the
registrants propose to maintain the use of these 2,4-DB[x]
compounds, and provide data to support the tolerances for
these salt, amine and esters.

         Rationale.  The registered uses for 2,4-DB are for the
2,4-DB[x] compounds and they must be a part of the tolerance
statement.

     7.  The Agency will require that registration be proposed
for use on mint and appropriate supporting data be submitted
or the Agency will revoke the tolerance of 0.2 ppm for residues
of 2,4-DB in or on mint hay.   Registrants will have three months
to notify the Agency of which option they choose.

         Rationale.  There is no registered use for mint.  Therefore,
this tolerance is unnecessary if registration is not proposed and
supporting data not submitted.

     8.  The Agency is requiring a groundwater warning statement
on the labels of 2,4-DB products.

         Rationale.  Although available data for phenoxy herbicides
suggest that the 2~,4-D family of compounds may be mobile in many
soil types, and has'the potential to contaminate groundwater, its
potential to contaminate groundwater is limited by its rapid rate
of degradation and uptake by target plants.  However, residues of
phenoxy herbicides have been detected in groundwater, mostly from
point sources, such as mixing, loading and disposal.  Since the
phenoxy herbicides could be a potential groundwater contaminant,
a label statement will advise users to exercise caution when
handling phenoxy herbicide products to prevent such contamination.
                              15

-------
 The Agency is currently finalizing its Agricultural Chemicals
 in Groundwater Strategy and its policy for restricting the
 use of pesticide products which may reach groundwater.   When
 the policies  are in  place,  the  Agency  will consider what
 action is appropriate  for phenoxy  herbicide products and
 other  products  containing ingredients  which may  reach
 groundwater.

     9.   The  Agency  is  requiring the use  of gloves  *rhen  lining,
 loading  or  applying  2,4-DB  products.

          Rationale.  The  major  route of exposure  to workers
 handling 2,4-DB~is~ dermal.   Use  of  gloves  will mitigate
 potential hazards  involving dermal  exposure.

     10.   The  Agency  is  not  requiring a reentry interval  for  2,4-D3
 products.

         Rationale.   Based on data  available to the  Agency, 2,4-DB
 products  are  of  fow  toxicity and the time  of the  application
 coupled  with  dissipation  limits  the exposure of workers  ree.ntering
 the  area  of application.   There  are no reentry concerns  with  this
 chemical  at the  present time.

     11.   The  Agency  is  requiring analytical chemistry  for  2,4-D3
 products  to evaluate contamination  with tetra- through
 heptahalognated  dibenzo-p-dioxins or dibenzofurans,  and  N-
 nitrosamines.

          Rationale.  Polyhalogenated dibenzo-p-dioxins or
 dibenzofurans may be formed  during  manufacture of 2,4-DB, and
 N-nitrosamines may be formed during the manufacture  or storage
 of products containing  2,4-DB amines.  The  Agency does not
 have sufficient  data to determine the extent or* significance  )"
 the contamination.

     12.   The  Agency will  immediately review certain  data as  they
 are submitted.

          Rationale.  Because  of  concerns  regarding potential
 risks from 2,4-D~B"use,  the  Agency believes  it is essential that
 the following data be reviewed as they are  received:  all toxi-
 cological studies; dioxin, furan and nitrosamlne analysis;
 octanol/ water partition coefficient;  vapor pressure; leaching
and adsorp'ci-on/desorptlon; spray drift; plant and animal
metabolism studies and validation methods; and freshwater fish
and invertebrate acute toxicity studies.
                                16

-------
    13.  While data gaps are being filled, currently registered
manufacturing-use products and end-use products containing 2,4-DB
may be sold, distributed, formulated, and used, subject to the terms
and conditions specified in this Standard.  However, significant new
uses will not be registered.  Registrants must provide or agree
to develop additional data, as specified in the data tables,  in
order to 
-------
B.  CRITERIA FOR REGISTRATION

    To be registered or reregistered under this Standard,
manufacturing-use products (MPs) and end-use products (EPs)
must contain 2,4-DB acid or 2,4-DB[x] compounds, bear required
labeling, and conform to the product composition, acute
toxiclty limits, and use pattern requirements listed in this
document.

0.   ACCEPTABLE_RANGES_ANDLIMITS

    1.  Product Composition Standard

        To conform to this Standard, MPs and EPs must contain
2,4-DB acid or 2,4-DB[x] compounds.   Each formulation proposed for-
registration must be fully described with an appropriate certifi-
cation of limits, stating maximum and minimum amounts of active
and inert ingredients present in the product as well as impurities.

    2.  Acute_To_x_icity Limits

        The Agency will consider registration of technical grade,
MPs, or EPs containing 2,4-DB acid or 2,4-DB[x] compounds, provided
the products are supported by appropriate acute toxicity data and
the labeling for the product bears appropriate precautionary state-
ments for the toxicity category in which the product is placed.

    3.  Use Patterns

        To be registered under this  Standard, MPs must be labeled
for formulation into other MPs or into EPs bearing federally-
registered uses.  The use index (EPA Compendium of Acceptable Uses)
lists all federally-registered uses  of 2.4-DB acid and 2,4-DB[x]
compounds, as well as approved maximum application rates and
frequencies.

        The use patterns currently registered are terrestrial
food.
                                   18

-------
 D.   LABELING

     All  products must bear appropriate labeling as specified in
 40 CPR 156.10, PR Notices 83-2, 83-3, and 87-1, and below.
 Appendix II contains further information on label requirements.

     1.  Timeframes for Compliance

        Pesticide products containing 2,4-DB acid or 2,4-DB[x]
 compounds may not be released for shipment by the registrant after
 October 1, 1989 unless the product bears amended labeling that
 complies with the requirements of FIFRA, as set forth in this
 Registration Standard.

        Pesticide products containing 2,4-DB acid or 2,4-DB[x]
 compounds may not be distributed or sold by any person after
 October 1, 1990 unless the product bears amended labeling that
 complies with the requirements of this Standard.

        In addition to the labeling requirements above, the
 following must appear on the labeling of all MPs  and EPs.

     2•  Ingredient Statement

        The ingredient statement for 2,4-DB products must list
 the  active ingredient as:

             4-(2,4-dichlorophenoxy)butyric acid  ....  	%

                   or

             4-(2,4-dichlorophenoxy)butyric acid,
               (salt, amlne or ester) 	  	%
             4-(2,4-dichlorophenoxy)butyric acid
               equivalent	* . .
    3.  Use _Pjittern ^Statements

        All manufacturing-use products must state that they are
intended 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.

-------
    4.  Precautionary Statement

        a.  Envirqnmental_Hazards

            1)  Manufacturing-use products:  "Do not discharge
effluent containing this product into lakes, streams, ponds,

-------
            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 not require the submittal of product-specific data for
end-use products at this time.  Therefore, most Registration
Standards do not contain a Table C.
                              21

-------
     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-use producers lose the exemption, and become subject
to the data requirements in Table A.
                             22

-------
       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
tie 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.
                                23

-------
     If you are not now eligible for a generic data
exemption, you may qualify for one if you change your source
of supply to a registered source that does not share
ownership in common with your firm.   If you choose to change
sources of supply, the Confidential  Statement of Formula must
identify the new source(s) and you must submit a 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
                              24

-------
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.
                              25

-------
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
     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 time-frames 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
                               26

-------
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 r equ i r ement.

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
be modified as appropriate so that the data generated by the
study will satisfy the requirements of Part 158.  Normally,
the Agency will not extend deadlines for complying with data
requirements when the studies were not conducted in accord
with acceptable standards.  The OECD protocols are available
from OECD, 1750 Pennsylvania Avenue, N.W., Washington, D.c.
20006.

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
                               27

-------
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
                                28

-------
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.
                               29

-------
  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.
                               30

-------
    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.
                               31

-------

I.  DATA APPENDICES
 35

-------
                       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 P.art 158.
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 Prot Royal Road, Springfield, VA
22161.

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

     TGAI  = Technical grade of the active ingredient
     PAI   = Pure active ingredient
     PAIRA = Pure Active ingredient, radio labeled
     TEP   = Typical end use formulation
     MP    = Manufacturing use product
     EP    = End use product

Any other test substances, such as metabolites, will be
specifically named in Column 2 or in footnotes to the table.

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

     A = Terrestrial, food
     B = Terrestrial, non-food
     C = Aquatic, food
     D = Aquatic, non-food
     E = Greenhouse, food
     F = Greenhouse, non-food
     G = Forestry

-------
     H = Domestic outdoor
     I = Indoor

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

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

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

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

     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 information.

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

6.   Must additional data be syb. nutted.? (Column 6).   This
column indicates whether the data must be submitted to the
Agency.  If column 3 indicates that the Agency already has
data, this column will usually indicate NO.  If column e
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 6
requires that data be submitted, this column indicates when
                           37

-------
the data are to be submitted, based on the issuance date of
the Registration Standard.   The timeframes are those
established either as a result of a previous Data Call-in
letter, or standardized timeframes established by PR Notice
85-5 (August 22, 1985).

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

 1/Requirements apply to 2,4-DB Acid as well as  to the  sodium  salt,  dlmethylamine, 2-butoxyethyl ester, butyl ester, and
   isooctyl ester forms, where [x] refers  to the substituted salt, amine or ester.
 2/For Magnitude of the Residues in Crops, the timeframes  for  submitting data are 18 or 24 months, as appropriate
 ~~ commencing with the 1989 planting season.
 3/Data depicting the distribution and metabolism  of ring-labeled [lilC]2,4-DB in or on alfalfa, soybeans (mature seed
   and forage), and an oilseed crop.  IT metabolisa is  not similar In these three crops, additional studies using other
   crops may be required.  A completely characterized test substance representative of technical 2,4-DB (including
   impurities) used In commercial formulations must be  applied foliarly at rates sufficiently high to permit characteri-
   zation of i4c-residues.  Sample intervals must  Include  the  day of application and the identities and quantities of
   residues in or on mature plant parts must be  determined in  order  to elucidate terminal residues.  Representative
   samples must also be analyzed by proposed and/or existing enforcement methods to ascertain that all residues of
   concern are determined.
 VMetabolisrn studies using ruminants and  poultry must  be  submitted.  Animals must be dosed for at least 3 days with
   ring-labeled [1^C]2,4-DB (acid) at a level high  enough  to permit quantification of the ^C-resldues. If necessary
   hydrolysis and reextraction of samples  and aqueous fractions must be applied to release any l4Q_conjUgates.  Milk
   and eggs must be collected within 24 hours of the  final dose.  The distribution and characterization of residues must

   be determined in milk, eggs, liver, kidney, muscle,  and fat.  Samples from these studies must also be analyzed using
   all current and proposed enforcement methods to ascertain that the methods are capable  of  adequately  recovering and
   quantifying all residues of toxicologic concern.  [If the required plant metabolism studies  using a radiolabeled
   dimethylarnlne salt of 2,4-DB reveal that dlmethylamine, per se, and/or the dimethylamine salt will occur as a
   residue in or on alfalfa, birdsfoot trefoil, clover, mint", peanuts, soybeans, and soybean  hay, metabolism  studies
   in ruminants and poultry are also required using [l^G]dimethylamine or the [l^C] dimethylamine salt.]
 ^/Data depicting the nature of 2,4-DB residues in swine are also required if the required metabolism studies with
   ruminants and poultry reveal that the metabolism of 2,4-DB in these animals differs from that in rats.
 _6/A PAM Vol. I, Section 222 multiresidue protocol for the determination oF chlorophenoxy  acids and esters is
   currently employed for enforcement purposes and will suffice for the testing of  2,4-DB  per se under the PAM I
   protocols I-IY [40 OPR 158.240(b)(15)].
 7/If the required animal metabolism data reveal metabolites of concern, analytical methods for data collection
   and tolerance enforcement (including multiresidue procedures) will be required.
 j8_/All residue data requested in this Standard inust be accompanied by sample storage data  (storage conditions and time
   stored) and data depicting the stability of residues under the conditions and for the time Intervals  specified.
 9/Data depicting 2,4-DB residues of concern In or on soybeans harvested 60 days after a single postemergence broadcast
   application with the soluble concentrate liquid (SO/L) sodium (Na) salt of 0.05  Ib ai/A and  the emulsifiable concen-
   trate (EC) dlmethylamine (DMA) salt at 0.06 Ib ai/A.  Each formulation must be applied  in  5  gallons of water using
   aerial equipnent (in separate tests).  Otests must be conducted in IL (1655), IN  (8%), IA (14%), and MM (9/0 or  OH (1%)
   since these States collectively produced ca. 50% of the 1984 U.S. soybean crop and represent the major U.S. soybean
   production regions.
j.O/If no detectable residues of 2,4-DB are observed at a 5X application rate, no processing study is required.  If howev
   the needed data indicate that measurable,  weathered residues occur in soybeans,  a processing study must be submitted
   depicting 2,4-DB residues of concern in the processed commodities meal, hulls, soapstock,  crude oil,  and refined oil,
   and the milling dust from soybeans.
_ll_/Data depicting 2,4-DB residues of concern in or on soybeans harvested 60 days after a single postemergence broadcast
   application with the SC/L Na salt of 0.05  Ib ai/A and the EC DMA salt at 0.05 Ib a I/A.   Each formulation must  be
   applied in 5 gallons of water using aerial equipment (in separate tests).  Tests must be conducted in IL (16%),
   IN (8%), IA (14%), and MM (9%) or OH (7%)  since these Stabes collectively produced ca.  50% of the 1984 U.S. soybean
   crop and represent the major U.S. soybean production regions.
^12/Data depicting 2,4-DB residues of concern  In or on Forage and hay of established alfalfa harvested 30 days following
   aerial application oF an EC formulation of the dimethyl am I ne salt at 1.5 Ib ae/A and the 2 Ib ae/gal  EC formulation
   of the isooctyl ester at 1.0 Ib ae/A each  in a separate test.  The tests must be conducted In CA (8%), CO  (3%), or
   NE (6%); IA (7%), IL (4%), or KS (5%); MI  (6%), MN (7%), SD (4%) or WI (12%), and NY (3%), OH (3%), or PA  (3%) which

   aerial application of an EC formulation of  the  dimethylamine salt at  1.5 lb ae/A and the 2 Ib ae/gal EC formulation
   of the butoxyethanol ester at 1.0 lb ae/A each  in  a separate test. The tests must be conducted in CA (8$), CO (350,
   or NE (6%); IA (7%), IL (4%), or KS (5%); MI (6%),  MN (7%),  SD (4%) or WI  (12%), and NY (3%), OH (3%), or PA (3%)
   which collectively accounted for ca. 70% of the 1985 U.S. production  of alfalfa.
14/Data depicting 2,4-DB residues of concern in or on forage and  hay of  clover harvested 60 days following a single
   postemergence broadcast application of an EC EMA salt formulation at  1.5 lb ae/A and the 2 lb ae/gal EC isooctyl
   ester formulation at 1 lb ae/A.  Each formulation  must be applied in  5 gallons of water using aerial equipment
   (in separate tests).  Tests must be conducted in CA (99% ladino clover), IL (11% red clover) or MO (11% red clover),
   and OR (29% alsike clover) because these States represent the  major regions of 1982 U.S. clover acreage.
jVData required for alfalfa will be translated to birdsfoot trefoil. Refer  to footnotes 13 and 14 for details of
   data requirements.
16/Data reflecting 2,4-DB residues of concern  in or on mint hay harvested at  the minimum interval between application
   and harvest (ca. 60 days) following a single postemergence application of  the 1.75 lb/gal EC EMA salt and the 2 lb/
   gal EC isooctyl ester formulations at 1 lb  ae/A in separate tests. Tests  must be conducted  in OR and WA since
   these States produced 74% of the 1985 U.S.  mint (spearmint and peppermint) grown for oil.
17/Data 2,4-DB residues of concern in or on peanuts harvested 30  days following the last of two applications of
   an EC formulation of the 2,4-DB dimethylamine salt (030819)  at 0.4 lb ae/A.  Test must be conducted in AL (36%)/
   PL (5%)/GA (13%) and NC (28%)/VA (18%), States  which collectively account  for ca. 100% of 1985 commercial peanut
   production, excluding product in Ml, OK, and TX.
18/Data depicting 2,4-DB residues of concern in meal,  crude and refined  oil,  and soapstock processed from
   peanuts bearing measurable weathered residues.   If residues  concentrate in any of these processed commodities,
   then appropriate food/feed additive tolerance must be proposed.
19/Following receipt and evaluation of the required plant and animal metabolism data and residue data for soybeans
   and nongrass animal feeds, specific data requirements for livestock feeding studies will be established.

158.340 Toxicology Footnotes

 I/Requirements apply to 2,4-DB Acid as well  as  to  the  sodiun salt,  dlmethylamine, 2-butoxyethyl ester, butyl ester and
  " isooctyl ester forms, where [x] refers  to  the substituted salt, amine or ester.
 2/This test is required only for compounds which are organophosphate inhibitors of cholinesterase, or related to
 ~~ such inhibitors or metabolites of such  inhibitors.   2,4-DB compounds are not organophosphates, therefore, a study is
   not required.
 3/This requirement is waived for 2,4-DB Acid/sodium  salt based on the submission of an acceptable chronic feeding
 ~~ study in the rat.
 VThis study is not required for the registered use  patterns.
 5/Since an acute neuroto*Lolty study is not  required,  this study is  not required.
 I/This study will be required for the amine  and esters if basic studies show significant toxicology difference from the
 ~~ 2,4-DB Acid/sodium salt, or will be required  if  residues of the amine or esters appear on the raw agricultural
   commodities.
 7/Either a new study is required or the mouse oncogenicity study on file must be upgraded to acceptable by submission
 ~~ of historial control data on tumor incidences (bronchiolar adenomas and carcinomas, as well as hepatocelluar
   carcinomas) from males of this strain of mice at the testing facility and justification that 750 ppn in the Maximum
   Tolerated Dose in female mice of this strain.
 8/An acceptable CHO/HGPRT study without metabolic  activation is required for 2,4-DB Acid.
 9/A special neurotoxicity study for 2,4-DB compounds is  reserved pending the outcome of the 2,4-D neurotoxicity study.

I/Requirements apply to 2,4-DB Acid as well as to the sodiun salt, dimethyl ami ne, 2-butoxyethyl ester, butyl ester and
  isooctyl ester forms, where [x] refers to the substituted salt, amine or ester.
^/Reentry data requirements are not being Imposed under this Standard.  Although 2,4-DB [x] products are registered
  for use on crops whose production and/or harvest would require human tasks characterized by a likelihood of dermal
  and inhalation exposure, time of application coupled with dissipation limits the exposure of workers reentering
  area of application.  In addition, 2,4-DB [x] does not meet the toxlcity requirements for §158.340.
_3_/Spray drift data are being required under this Standard because 2,4-DB [x] meets the phytotoxicity requirement
  §158.440.  The droplet spectrum study is to be performed to reflect the nozzle and other equipment types to be
  used In the application of 2,4-DB [x] to crops.  The spray drift field evaluation to be performed to reflect
  the application equipment, use pattern, and typical locations of use, which includes different weather factors,
  in the application of 2,4-DB [x] for these uses.

                          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
test.  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-
ment 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)]

     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

     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.  [40CFR 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

     Item 7E.  REFERRAL STATEMENT - The statement "see Side (or
Back) Panel for Additional Precautionary Statements" is required
on the front panel for all products, unless all required
precautionary statements appear on the front panel.
[40 CFR 156.10(h)(1)(iii)]
                            69

-------
                            SUMMARY-3

     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)]

     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 flammability statements.

     Item 9A.  RESTRICTED USE CLASSIFICATION - FIFRA see. 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).
                                70

-------
                            SUMMARY-4

     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 classification
determination will be evaluated in accordance with the provisions
of 40 CFR 162.11(c).  You will be notified of the Agency's
classification decision.

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
                                -7

-------
                                SUMMARY-5

          simultaneously.  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.

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

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

     Item-IOC.  DIRECTIONS FOR USE - Directions for use must be
stated in terms which can be easily read and understood by the
average person likely to sue 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.

Chapter I—Environmental Protection Agency


§156.10  Labeling Requirements for Pesticides  and  Devices.

  (a)  General—(1)  Contents of the label.  Every pesticide
product shall bear a label containing the information specified  by
the Act and the regulations in this Part.  The contents  of  a
label must show clearly and prominently the following:
  (i)  The name, brand, or trademark under  which  the product  is
sold as prescribed in paragraph (b) of this section;
  (ii)  The name and address of the producer,  registrant,  or
person for whom produced as prescribed in paragraph (c)  of  this
section;
  (iii)  The net contents as prescribed in  paragraph (d) of this
section;
  (iv)  The product registration number as  prescribed in paragraph
(e) of this section;
  (v)  The producing establishment number as prescribed  in  para-
graph (f) of this section;
  (vi)  An ingredient statement as prescribed  in  paragraph  (g)  of
this section;
  (vii)  warning or precautionary statements as prescribed  in
paragraph (h) of this section;
  (viii)  The directions for use as prescribed in paragraph (i)
of this section; and
  (ix)  The use classification(s) as prescribed in paragraph (j)
of this section.
  (2)  Prominence and legibility.  (i)  All words, statements,
graphic representations, designs or other information required  on
the labeling by the Act or the regulations in this part  must be
clearly legible to a person with normal vision, and must be placed
with such conspicuousness (as compared with other words, state-
ments, designs, or graphic matter on the labeling) and expressed
in such terms as to render it likely to be read and understood
by the ordinary individual under customary conditions of purchase
and use.
  (ii)  All required label text must:
  (A)  Be set in 6-point or larger type;
  (B)  Appear on a clear contrasting background;  and
  (C)  Not be obscured or crowded.
  (3)  Language to be used.  All required label or  labeling text
shall appear in the English language.  However, the Agency may
require or the applicant may propose additional text in other
languages as is considered necessary to  protect the public.  When
additional text in another language  is necessary,  all labeling
requirements will be applied equally to  both  the  English and
other-language versions of the  labeling.
  (4)  Placement of Label—(i)  General.  The label shall  appear
on or be securely attached to  the  immediate container of the
                                   76

-------
 pesticide  product.   For purposes of  this Section, and the mis-
 branding provisions  of the Act, "securely attached" shall mean
 that  a  label  can  reasonably be expected to remain affixed during
 the  foreseeable conditions and period of use.   If the immediate
 container  is  enclosed within a 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 is in transit, the  appropriate
 provisions of  49  CFR Parts 170-189,  concerning  the transportation
 of hazardous  materials, and specifically those  provisions con-
 cerning the labeling, marking and placarding of  hazardous materials
 and  the vehicles  carrying them, define the basic Federal require-
 ments.  In addition, when any registered pesticide product is
 transported in a  tank car, tank truck or other  mobile or portable
 bulk  container, a copy of the accepted label must be attached to
 the shipping  papers, and left with the consignee at the time of
 delivery.
   (B)   Storage.  When pesticide products are stored in bulk
 containers, whether  mobile or stationary, which remain in the
 custody of the user, a copy of the label of labeling, including
 all appropriate directions for use,  shall be securely attached to
 the container  in the immediate vicinity of the  discharge control
 valve.
   (5)   False  or misleading statements.  Pursuant to section
 2(q)(l)(A) of  the Act, a pesticide or a device  declared subject
 to the  Act pursuant  to § 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;
                                     77

-------
  (ix)  Claims as to the safety of the pesticide or its ingredients,
including statements such as "safe," "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)(ii) of this section, final printed labeling must
be submitted and accepted prior to registration.  However, final
printed labeling need not be submitted until draft label texts
have been provisionally accepted by the Agency.
  (ii)  Clearly legible reproductions or photo reductions will be
accepted for unusual labels such as those silk-screened directly
onto glass or metal containers or large bag or drum labels.  Such
reproductions must be of microfilm reproduction quality.
  (b)  Name, brand, or trademark.  (1)  The name, brand, or
trademark under which the pesticide product is sold shall appear
on the front panel of the label.
  (2)  No name, brand, or trademark may appear on the label which:
  (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 § 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."
                                    78

-------
  (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.
                                  79

-------
  (3)  Names to be used in ingredient statement.   The  name  used
for each ingredient shall be the accepted common  name,  if there
is one/ followed by the chemical name.   The common name may be
used alone only if it is well known.   If no common name has been
established, the chemical name alone  shall be used.  In no  case
will the use of a trademark or proprietary name be permitted unless
such name has been accepted as a common name by the Administrator
under the authority of Section 25(c)(6).
  (4)  Statements of percentages.  The  percentages of  ingredients
shall be stated in terms of weight-to-weight.  The sum of per-
centages of the active and the inert  ingredients  shall be 100.
Percentages shall not be expressed by a range of  values such as
"22-25%."  If the uses of the pesticide product are expressed as
weight of active ingredient per unit  area, a statement of the
weight of active ingredient per unit  volume of the pesticide
formulation shall also appear in the  ingredient statement.
  (5)  Accuracy of stated percentages.   The percentages given
shall be as precise as possible reflecting good manufacturing
practice.  If there may be unavoidable  variation  between manu-
facturing batches, the value stated for each active ingredient
shall be the lowest percentage which  may be present.
  (6)  Deterioration.  Pesticides which change in chemical
composition significantly must meet the following labeling re-
quirements :
  (i)  In cases where it is determined that a pesticide formulation
changes chemical composition significantly, the product must bear
the following statement in a prominent position on the label:   "Not
for sale or use after  [date]."
  (ii)  The product must meet all label claims up to the expiration
time indicated on the label.
  (7)  Inert ingredients.  The Administrator may require the name
of any inert ingredient(s) to be listed in the ingredient  statement
if he determines that such ingredient(s) may pose a hazard to man
or the environment.
  (h)  Warnings and precautionary statements.  Required warnings
and precautionary statements concerning the general areas  of
toxicological hazard including hazard to children, environmental
hazard, and physical or chemical hazard fall  into  two  groups; those
required on the front panel of the labeling and those  which may
appear elsewhere.  Specific requirements concerning content,
placement, type size, and prominence are given below.
  (1)  Required front panel statements.  With  the  exception  of  the
child hazard warning statement,  the  text required  on  the front
panel of the label is determined by  the Toxicity  Category  of the
pesticide.  The category is assigned on the basis  of  the highest
hazard shown by any of the  indicators  in  the  table  below:
                                  80

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

              on the front panel
                                 8

-------
  (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
 warnincs 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.
    (B)   The  following table depicts  typical precautionary statements.
 These  statements must  be modified or expanded  to reflect specific
 hazards.

[No precautionary statements required.],
   (ii)   Environmental  hazards.  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
                                         83

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 LD5Q of 100 or less, the
statement  "This Pesticide is Toxic to Wildlife" is required.
   (B)   If  a pesticide iatended for outdoor use contains an active
ingredient with a fish acute LC$Q of 1 ppm or less, the statemeni
"This Pesticide is Toxic to Fish" is required.
   (C)   If  a pesticide intended for outdoor use contains an activs
ingredient with an avian acute oral LD$Q of 100 mg/kg or less, 01
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

  O)  The product as finally manufactured, formulated, mixed, or
repackaged is registered; and
  (£)  The Administrator determines that such directions are not
necessary to prevent unreasonable adverse effects on man or the
environment.
  (2)  Contents of Directions for Use.  The directions for use
shall include the following, under the headings  "Directions for
Use" :
  (i)  The statement of use classification as prescribed in
162.10(j) immediately under the heading "Directions for Use."
  (ii)  Immediately below the statement of use classification,
the statement "It is a violation of Federal law to use this
product in a manner inconsistent with its labeling."
  (iii)  The site(s) of application, as for example the crops,

pesticide may be applied under the direct  supervision  of  a
certified applicator who is not physically present at  the site  of
application but nonetheless available  to the person  applying  the
pesticide, unless the Agency has determined that  the pesticide
may only be applied under the direct  supervision  of  a  certified
applicator who is physically present.
                                   86

-------
  (F)  Other pertinent information which  the Administrator
determines to be necessary for the protection of  man and  the
environment.
  (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 § 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.
                              89

-------
               PESTICIDE DISPOSAL INSTRUCTIONS
The label of all products, except those intended solely for
domestic use, must bear explicit instructions about pesticide
disposal.  The statements listed below contain the exact
wording that must appear on the label of these products:

1.   The labels of all products, except domestic use, must
     contain the statement:

          "Do not contaminate water, food, or feed by storage
          or disposal."

2.   Except those products intended solely for domestic use,
     the labels of all products that contain active
     ingredients that are Acute Hazardous Wastes or are
     assigned to Toxicity Category I on the basis of oral or
     dermal toxicity, or Toxicity Category I or II on the
     basis of acute inhalation toxicity must bear the
     following pesticide disposal statement:

          "Pesticide wastes are acutely hazardous.  Improper
          disposal of excess pesticide, spray mixture, or
          rinsate is a violation of Federal Law.  If these
          wastes cannot be disposed of by use according to
          label instructions, contact your State Pesticide or
          Environmental Control Agency or the Hazardous Waste
          representative at the nearest EPA Regional Office
          for guidance."

3.   The labels of all products, except those intended for
     domestic use, containing active or inert ingredients
     that are Toxic Hazardous Wastes or meet any of the
     criteria in 40 CFR 261, Subpart C for a hazardous waste
     must bear the following pesticide disposal statement:

          "Pesticide wastes are toxic.  Improper disposal of
          excess pesticide, spray mixture, or rinsate is a
          violation of Federal Law.  If these wastes cannot
          be disposed of by use according to label
          instructions, contact your State Pesticide or
          Environmental Control/Agency, or the Hazardous
          Waste representative at the nearest EPA Regional
          Office for guidance."

4.   Labels for all other products, except those intended for
     domestic use, must bear the following pesticide disposal
     statement:
                               90

-------
          "Wastes resulting from the use  of  this  product  may

III.  BIBLIOGRAPHY APPENDICES
               9

-------
               Guide to Use of This Bibliography

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

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

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

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

       a.   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
                                 94

-------
     laboratory or testing facility as author.   As a
     last resort, the Agency has shown the first
     submitter as author.

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

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

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

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

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

     (3)  Submitter.  The third element is the
          submitter, 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 conmitted 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.

Registrant's authorized representative:
