                       I.  INTRODUCTION

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

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

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

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

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

     The detailed scientific review, which is not contained
in this document, but is available upon request', focuses on
the pesticide active ingredient.  The scientific review
primarily discusses the Agency's evaluation of and conclusions
from available data in its files pertaining to the pesticide
active ingredient.  However, during the review of these data
the Agency is also looking for potential hazards that may be
associated with the end use products that contain the active
ingredient.  The Agency will apply the provisions of this
Registration Standard to end use products if necessary to
protect man and the environment.

-------
      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 PIPRA.  These steps may  include:

      1.  Submission of  data In support of product  registration;

      2.  Modification of product labels;

      3*  Modifications  to the manufacturing process of the
 pesticide to reduce the levels of Impurities or  contaminants;

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

      5.  Modification of uses or formulation types; or

      6.  Specification of packaging limitations.

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

      In addition, In cases in which hazards to man or the
 environment are identified, the Agency may  initiate a special
 review of the pesticide in accordance with  40 CPR  Part 151
 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 PIPRA sec.  3(c)(2)(B)  to require that registrants submit
 data to answer our questions regarding the  chemical,  toxlcologlcal,
 and environmental characteristics and fate  of a  pesticide.
 This Registration Standard  lists the data EPA believes are
 necessary to resolve our concerns about this pesticide.
 These  data are listed in  the Tables A,  B, and C  in Appendix I.
 Failure to comply with  the  DCI requirements enumerated in
 this Registration Standard  may result  in Issuance  by EPA of a
 Notice of Intent to Suspend the affected product registrations.

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

-------
the Agency of any Information, including interim or preliminary
results of studies, if that information suggest possible
adverse effects on man or the environment.  This requirement
is Independent of the specific time requirements imposed by
EPA for submission of completed studies called in by the
Agency and continues as long as a product is registered
under PIPRA.

-------
C.  HISTORY

    MH was synthesized and determined to have growth
inhibiting properties in 1947.   The chemical  was first
registered in 1952.   In October 1976 it was referred to
the Agency for RPAR.   The referral was based  on laboratory
studies which indicated that MB induced oncogenic,  mutagenic,
and reproductive effects.  In October 1977, the Agency initi-
ated an RPAR review by publishing a PD 1 for  MH.  The PD 1
described studies which met or exceeded the RPAR criteria
for oncogenic, mutagenic, and reproductive effects.

     The Agency did not issue the PD 2/3 for  maleic hydrazide
because of the absence of adequate risk data  for oncogenic,
mutagenic and reproductive effects.  Agency scientists could
not adequately assess the risk potential of maleic hydrazide
because of the paucity of valid toxicological information and
conflicting results within each data base.  To fill these
data gaps, the Agency required all MH registrants to submit
data regarding the reproductive -effects and mutagenic poten-
tial of DEA-MH and K-MH pursuant to the authority of section
3(c)(2)(B) of FIFRA.   The Notice announcing these data require-
ments for MH was sent to all registrants on August 14, 1980.

    The manufacturers agreed to .submit, the required data
on K-MH on February 26, 1981.  Because manufacturers of the
DEA-MH decided not to submit the required additional data,
the Agency suspended all DEA-MH registrations in November
1981.  The suspension may be lifted at such time that
there is compliance with the data request.

    The information submitted in response to the Data Call In
Notice was evaluated.  The Agency determined that two of three
RPAR triggers (oncogenicity and reproductive effects) were not
supported.  Although mutagenicity was an initial RPAR trigger,
our criteria for special review in this area area has become
more rigorous and focused on confirmation of effects  in mammalian
systems.  The limited mutagenicity data available is generally
negative.  Additional data are required by this document.

    During the evaluation of the available oncogenic  studies,
the agency determined that consideration of hydrazine con-
tamination might help determine the oncogenic potential of
maleic hydrazide.  The Agency reached this hypothesis because
two similar studies showed different results: Epstein and
Mantel (1968) reported an increased incidence of hepatomas,
where as Cabral at al.(1981) reported no significant  increase
in tumor incidence.  A primary difference  between the two
studies was the level of hydrazine contamination in  the MH
they used: 4000 ppm in the Epst-ein study and  less than  1  ppm
in the study by Cabral.
                               -5-

-------
      Several studies show a definite relationship between
hydrazine and tumor induction.  The Agency used a study
by Biancifiori in which a dose related induction of hepatomas
was observed and the one hit model was used to determine
the lifetime risks to humans.  In calculating the risk from
maleic hydrazide it was assumed that the hydrazine contamination
is 15 ppm, the highest level reported in currently registered
technical MH products.  The estimated oncogenic risks did not
cause concern and the Agency consequently decided to terminate
the RPAR review of MH at that time.

     The Agency published a Position Document (PD-4) for
Maleic Hydrazide in June 1982.  The final determinations were
to terminate the RPAR to allow the continued use of potassium MH,
and to establish an acceptable limit of hydrazine at 15 ppm in
technical grade products to avoid the potential for unreasonable
adverse effects.
                               -6-

-------
                   III.  AGENCY ASSESSMENT
A.  SUMMARY SCIENCE STATEMENT

    MH has low acute toxicity (Toxicity Category III)  for
primary eye irritation and is in Toxicity Category IV  for
acute oral, acute dermal,  and primary dermal irritation.
MH caused no adverse reproductive effects;  was  not oncogenic
to mice; and not mutagenic.  The teratology study in rabbits
had a teratogenic NOEL of  100 mg/kg/day (malformed scapulae
occurred in the mid and high dose).   An exposure assessment
was performed and it was determined  that MOSs were < 100  for
mixer/loaders, therefore,  of potential concern.  The Agency
is requesting additional teratology  data to fully define  the
teratogenic effect.  To reduce exposure to applicators this
standard requires that the label be  amended to  require
protective clothing while  handling,  applying, mixing or loading
the chemical.

    MH was stable to hydrolysis and  photodegradation in
soil.  It photodegraded in buffered  aqueous solutions  at
pH 5, 7, and 9.  MH was very mobile  in five soils and  has
a low potential to bioaccumulate in  fish.  Additional  persis-
tance and leaching data are needed to evaluate  MH's potential
to contaminate ground water.

    MH is considered practically nontoxic to birds, aquatic
invertebrates, freshwater  fish, or honey bees.   Endangered
animal species are not expected to be adversely affected  by
the use of MH.  Since no endangered  plant species are  listed
for tobacco cropland, citrus, apples, potatoes  and onions
or canberries, little risk is expected to endangered
plants from these uses.  A hazard assessment for the right-of-way
use is deferred until the  Agency develops the non-cropland
cluster.

B.  TOXICOLOGICAL CHARACTERISTICS

    There are three forms  of maleic hydrazide registered, the
technical, the K salt, and the DEA salt. All DEA salt registra-
tion were suspended in 1981 for failure to submit data in re-
sponse to a data call in notice.  Some of the data discussed
below are on the parent and some of it are on the K salt.  For
this Standard, they will be considered equivalent.

    Even though the DEA salt is suspended, the suspension may
be lifted at such time that manufacturers comply with the
data request.

-------
Because there nay be qualitative or quantitative differences
in the behavior of the DEA salt due to the DEA moiety,  and
because the DEA moiety itself may be oncogenic or cause
other effects not seen with the other salts, a separate set
of toxicology studies are required for the DEA salt.   Refer
to the discussion below, and Table A-2, for specific  data
requirements.
                             8

-------
    Acute Toxicity

    Acute oral and acute dermal toxlcity studies  place MH in
Toxicity Category IV with an acute oral  toxicity  >  5  g/kg and
an acute dermal toxicity > 20 g/kg.  In  the dermal  toxicity
study, the test material caused only very slight  erythema and
edema resulting in a Toxicity Category IV classification.
These requirements are fulfilled for MH  but are required for
the MH-DEA salt.

    The available acute inhalation study did not  provide
enough detail for evaluation, therefore  an acute  inhalation
study is needed for both MH and MH-DEA.

    There are no data available on primary dermal
sensitization properties.  Therefore, dermal sensitization
studies for both MH and the MH-DEA salt  are needed.

    Subchronic Toxicity

    There are no data available on subchronic oral, dermal,
or inhalation toxicity.  The data requirement for subchronic
oral toxicity is waived for the parent^ the K salt,  and the DEA
salt because chronic studies are required for a rodent and a
nonrodent.

    A 21-day dermal toxicity study is required for both MH
and the DEA salt.  Ninety-day dermal subchronic studies are
not required for either the DEA salt or MH because existing
use patterns do not involve purposeful or prolonged dermal
exposure.

    Subchronic inhalation studies are not required at this
time, but may be required once the requested residue data on
tobacco are received and reviewed.

    Neurotoxicity

    There are no data available for acute delayed or subchronic
delayed neurotoxicity for either MH or the DEA salt.  Acute
delayed neurotoxicity studies are not required .because MH and
its salts are not organophosphates.  Subchronic neurotoxicity
studies are not required because acute neurotoxicity testing
is not required and there is no evidence of neurotoxicity in
mammalian species.

-------
     Chronic Toxlcity

     The available chronic  feeding  study  in rats is inadequate
 because a NOEL was not  established for renal toxicity and the
 raw data were  not available  for  review.  The available
 data indicate  that the  NOEL  is < 500 mg/kg (LOT).  There are
 no chronic feeding studies available for nonrodents.  Chronic
 feeding studies are required for both MH and the DEA salt on
 both rodents and nonrodents.

     Oncogenicity

     The oncogenicity potential in  rats could not be adequately
 determined because raw  data  (especially  histopathology) were
 unavailable for review. Therefore, .oncogenic studies with
 rats  are required for both MH and  the DEA salt of MH.

     Two recent oral oncogenicity studies are available to
 evaluate the oncogenic  potential of MH.  These studies
 collectively indicate that MH is not oncogenic in mice.
 These studies  are discussed  below.

     In a mouse oncogenicity  study  with common control
 performed by Cabral and Ponomarkov, group I mice were fed an
 oral  dosage of 510 mg/kg MH  daily  for 125 weeks; group II
 mice  were dosed as follows:  one  group of mice received several
 subcutaneous dosages totaling 55 mg/kg MH in the vehicle
 tricaprylin applied during the first three weeks after birth
 and  a second group of solvent control animals received the
 same  amount of pure tricaprylin  over the same period.  Both
 subgroups were sacrificed  after  125 weeks.  Untreated concurrent
 control  animals were shared  by both oral group I and subcutaneous
 treatment groups.   No compound-related effects were seen in
 group I.   In group II,  male  mice had a statistically significant
 increase in liver tumors when compared with untreated control
males,  but -the increase was  not  statistically different from
 the  solvent control males.   No evidence  of compound-related
oncogenic effects  was seen in females.   Because the group II
 results  could  be caused by either  the MH, a low level of hydrazine,
or an interaction between  MH or  hydrazine and the tricaprylin,
group II  could not be definitely interpreted.  Because group II
could  not be interpreted correctly and group I used only one
dosage,  this study was  classified  as Supplementary data.

    In a  second study performed  by IRDC, mice were fed oral
dosages  of  0,  150-200,  500-600,  1600-1800 mg/kg/day for
their  lifetime.   Hemangiomas  and lung adenomas and carcinomas in
females were considered  to be of potential concern.  When the
hemangiomas  from  all  sites were  combined, as is appropriate for
this  data set,  their  incidence was  judged not to be significant.


                         '      10

-------
While there was a significant trend in lung adenomas and/or
carcinomas, there were no significant pair-wise comparisons
between exposed and control mice, and the incidence of these
tumors were within the historical control range.   Therefore,
MH was not considered oncogenic in mice.

    Both group I of the cabral study and  IRDC study used mice,
dosed orally for their lifetime.  In both experiments, detailed
gross and microscopic pathologic examinations were performed on
a standard set of tissues and organs and  appropriate statistical
analysis were performed on the data.  The two studies were con-
sidered to be "supplementary" on their own, but collectively
provide an adequate data base to determine that maleic hydrazide
is not oncogenic to mice.  No additional  data are needed on this
potential effect for maleic hydrazide technical or the K salt.

    An oncogenic study with mice is required for the DEA salt
of MH.

    Teratoqenicity

    No data are available to determine teratogenic effects in
rats.  Therefore teratology studies are required in rats for
MH and the DEA salt of MH.

    A teratology study in rabbits fed K salt MH dosages of
0, 100, 300, and 1000 mg/kg/day is available.  No signs of
maternal toxicity were seen; therefore, the maternal NOEL is
1000 mg/kg/day (HDT).  Malformed scapulae were seen in 4 out
of 99 animals at the mid-dose and 2 out of 107 animals at the
high-dose.  Therefore the teratogenic NOEL is 100 mg/kg.  This
is a rare malformations seen in only 1 fetus out of 1586 fetuses
in the historical control.  This effect was considered signifi-
cant.  Therefore the Agency performed an applicator exposure
assessment.  Based on the exposure estimate, the MOSs for
dermal exposure for open-pour mixer/loaders for most applications
would be < 100 and a potential concern.  Based on this concern,
additional information on parentage of affected rabbits is •
requested.  Additional information may be required once this
information and the rat teratology study are reviewed.  Until
this is resolved a label statement requiring protective
clothing will be added. Refer to labeling section for the
wording of this label statement.

    A teratology study with rabbits is required for the DEA
salt of MH.

-------
     Reproduction

     The  available  two-generation  study fulfills this
 requirement  for MH.   No  adverse effects on reproduction were
 noted  in male  or female  rats  fed  dosages of 0, 75, 750, and
 2250 mg/kg.  The maternal  toxic NOEL is 750 mg/kg with a LOEL
 of  2250  mg/kg  (decreased parental weights).  The fetotoxic
 NOEL is  750  mg/kg  with a LOEL of  2250 mg/kg (decreased body-
 weights) .

     A  two-generation  reproduction study in rats is required
 for the  DBA  salt of MH.

     Mutagenicity

     No mutagenicity data are  available for the DEA salt of
 MH;  therefore, studies are required to satisfy gene mutation,
 chromosomal  aberrations, and  other mechanisms of mutagenicity.

     A mutagenicity study of sex-linked recessive lethal
 gene mutations in  Drosophila  revealed no sex-linked recessive
 lethal mutations at cytotoxic doses from 0.4 to 1.0 percent
 of  26.7  percent K-MH  in  water.  This fulfills the gene
 mutation requirement  for MH.  No  data are available on the
 mutagenicity of MH for chromosomal aberrations or other
 mutagenic mechanisms, therefore these data are required.

     Metabolism

     There are no metabolism studies available for MH or the
 DEA salt; therefore,  rat studies  of the absorption, distri-
 bution, metabolism, and  excretion after acute and repeated
 exposures are required for both MH and the DEA salt of MH.

 C.   PHYSIOLOGICAL  AND BIOCHEMICAL BEHAVIOR CHARACTERISTICS

     Absorption of  MH  by  roots and leaves is a function of
 cell turgidity with most effective absorption occurring when
 soil moisture is at field capacity and relative humidity is
high. Once absorbed,  MH  is rapidly translocated to leaves and
growing shoots.

     The mechanism  of  pesticide action for MH is believed
to be as a uracil  antimetabolite which interferes with cell
division, plant growth,  and maturation.  It also affects
respiration  through inhibition of one or more dehydrogenases.
                               12

-------
    Available tobacco metabolism data on MH indicate that the
major residues of MH in plants are the parent  and  its beta D-
glucoside conjugate.  Additional plant metabolism  data are
required.

    No data are available for metabolism of MH in  animals.
Metabolism studies using ruminants and poultry are required.

D.  ENVIRONMENTAL CHARACTERISTICS

    MH was stable to hydrolysis in buffered solutions at
pH 3, 6, and 9 when maintained at 45 °C for 61 days and 80 °C
for 30 days, and was stable to phot©degradation in soil after
17-day irradiation by artificial light.  MH photodegraded in
buffered aqueous solutions at pH 5, 7, and 9 with  half-lives  of
58 days at pH 5 and 7 and 34 days at pH 9 when irradiated by
artificial light.  Unaged MH was very mobile in a  silt loam
soil, a sandy clay loam soil, a sandy loam soil, and two sandy
soils with Kads values of 0.14 to 2.61 and Kdes values of 0.39
to 14.45.  Unaged MH was very mobile in soil columns of clay
loam and sandy loam soils.  Aged MH was very mobile in soil
columns of sandy loam and clay loam soils and  very mobile in
sandy loam soil with Kads value of 2.37 and the Kdes value
was 2.74.  MH dissipated in a field application with a half-
life of 3 to 7 days from the upper 6 inches of clay loam soil.

     MH has a low potential to bioaccumulate in fish with
octanol/water partition coefficient values of  < 0.6 at pH 6,
7, and 9.

    The available data are inconclusive for potential to
leach into ground water because of lack of information on
persistence of degradates under aerobic/anaerobic  soil con-
ditions.  The chemical is persistent in water  since it is
stable to hydrolysis.  The chemical is very mobile in five
soils.  Available field persistence data do not adequately
define the depth of leaching and are inconclusive.  The full
leaching potential of MH cannot be determined  until persistence
data are submitted and evaluated.  Once the leaching potential
of MH is determined, a ground water monitoring study may be
required.

    The data requirements for hydrolysis, photodegradation in
soil and fish accumulation are satisifed.  The following data
are required to fully assess the environmental fate of MH:
photodegradation in water, aerobic and anaerobic soil metabo-
lism studies, terrestrial field dissipation study, a soil
column and adsorption/desorption studies with aged MH, and a
confined accumulation study on rotational crops with wheat or
another small grain.  Additional data may be  required  if
requested studies indicate the need for additional data.


                            "    13

-------
 E.   EXPOSURE AND RISK

      During review of data  an  applicator  exposure assessment
 was  performed because of  rare  teratogenic effects (refer to
 discussion of teratogenic effects)  seen in  rabbits.  The
 exposure  estimates were based  on  data  available from the public
 literature for individuals  wearing  long sleeved shirts and long
 pants at  all times and chemical resistant gloves during mixing
 loading.   The estimates were not  adjusted for dermal absorption
 of MH and,  therefore, assume 100% dermal  absorption.  The MOS
 for  open-pour mixers-loaders were less than 100.  The MOS for
 closed system mixer loaders were  greater  than 100.  The MOS for
 pilots were greater than  1000.  Those  MOS's of less than 100 are
 of potential concern (Standard Evaluation Procedure for Teratology
 Studies,  June 1986).   To  evaluate these potential concerns, the
 Agency is requiring that  additional information on parentage of
 affected  animals be submitted  and that the  labeling be amended
 to require  protective clothing.   Refer to labeling section for
 wording required.   The Agency  is  planning a high priority on the
 review of the rat  teratology study.

      Reentry data  are not required  for MH because current use
 patterns  (7- to  70-day PHI  application to plants at early
 growth stage)  indicate little  likelihood  of exposure or low
 exposure  at this time, and  the placement  of the chemical in
 Toxicity  Category  IV for  acute oral and acute dermal toxicity
 indicate  minimal risk to  humans.

 F.   ECOLOGICAL CHARACTERISTICS

     Terrestrial  Organisms

     Based on acute oral toxicities  of  > 4640 mg/kg/day
 (technical)  and  >  2250 (K salt) to  mallard  ducks, MH tech-
 nical and K salt present  very  low toxicity  to avian species
 on an acute oral basis.   Available  data indicate that the
 8-day dietary toxicity of MH technical is > 10,000 ppm for
 both mallard ducks and bobwhite quail  and that the 8-day
 dietary toxicity'for  the  MH K  salt  is  > 5620 ppm for mallard
 ducks.  Based  on these data, the  technical  and R salt of MH
 present very low toxicity to avian  species  on a dietary
 basis.  The  requirements  for acute  oral toxicity and dietary
 toxicity  tests with avian species have been satisfied.  No
 data  are  required  for the DEA  salt  because  of the low order
 of toxicity to avian  species of the technical and K salt.
Avian  reproduction studies  are not  required because the only
 repeated  use  pattern  of MH  is  small (golf course fairways)
 and  the acute  oral and dietary toxicity values for birds show
 it to  present  very low toxicity.

    Mammals  are  not  expected to encounter risk from the use
of MH  or  the  K salt  based on low  acute toxicity to rats.

                                 14

-------
The timing of  application of MH on tobacco,  the major
agricultural use, is at the time of full flower presenting
exposure to honey bees in the area.  However, with a toxicity
value of > 36.26 ug/bee, MH presents very low toxicity to
honey bees; therefore honeybees in the area are not at risk.

    Aquatic Organisms

    Based on 48-hour acute toxicities of 107.5 ppm (technical)
and 1000 ppm (K salt), MH is considered to present very low
toxicity to freshwater invertebrates.  There are no data
requirements for the DEA salt based on the low order of
toxicity of MH (technical and K salt) to aquatic organisms.
The requirement for an acute toxicity study with freshwater
invertebrates has been satisfied.

    Based on acute toxicities of 1435 ppm (technical) to rain-
bow trout, 1608 ppm (technical) to bluegill and > 1000 ppm (K
salt) to rainbow trout, MH (technical and K salt) are considered
practically nontoxic to both coldwater and warmwater fish. There
are no data requirements for the DEA salt based on the low order
of toxicity of MH and the R salt to fish.  The requirements for
acute toxicity testing with freshwater fish are satisfied.

    The use of MH as a foliar application on tobacco and
roadway rights-of-way will not cause hazard to aquatic spe-
cies from runoff.  The EEC for foliar application of MH is
12 ppb.  The risk of MH to aquatic species inhabiting those
waters is low with a safety factor of over 1000 for aquatic
invertebrates, the most sensitive species.

    Plant Protection

    There are no data available for MH concerning phytotoxicity.
Because MH is a plant growth retardant and there is no previous
plant data base, the Agency assumes possible hazard to endan-
gered plant species.  Therefore, Tier I nontarget area
phytotoxicity testing is required.

    Endangered Species

    Because MH is a plant growth retardant, the Agency assumes
hazard to any endangered plants occurring in areas where MH
is used.  There are no endangered plants listed as occurring
in tobacco cropland, in citrus, apples, potatoes, onions,  or
cranberries, therefore there is no risk to endangered plants
from use of MH on these sites.  Evaluation of hazard to en-
dangered plants from use on right-of-ways will await evaluation
of all pesticides in the noncrop cluster.
                                 15

-------
    Because of the low toxicity of MH to mammals, avian
species, aquatic species, and the low potential for exposure
to MH, endangered animal species are not expected to be
affected by use of MH.

G.  PRODUCT CHEMISTRY

    The Agency has determined that product chemistry data for
all technical and MPs must be submitted for each pesticide
because new requirements.have been introduced and previously
submitted data must be updated.  Therefore, a complete set of
product chemistry data is required for the TGAI and MPs.

     During the RPAR review the Agency determined that hydrazine,
a contaminant of raaleic hydrazide products, is itself an oncogen
and that the amount of hydrazine occurring in technical products
must be ^ 15 ppm.  Refer to History Section for details.

    Available data indicate that nitrosamines may occur in EPs con-
taining the DEA salt of MH.  Because some nitrosamines are
known carcinogens, testing for nitrosamines will be required
for all end use products containing the DEA salt.


H.  TOLERANCE REASSESSMENT

    Tolerances Issued

    Tolerances are established for residues of the herbicide and
plant regulator MH (1,2-dihydro-3,6-pyridazinedione)(40 CFR 180.
175) in or on the RACs cranberries at 15.0 ppm; onions, dry bulb
at 15.0 ppm; and potatoes at 50.0 ppm.

    A food additive tolerance is established for residues of the
herbicide and plant regulator MH (1,2-dihydro-3,6-pyridazinedione)
(21 CFR 193.270) on potato chips at 160 ppm as a result of the
pesticide application to the growing potato plant.

    Canadian tolerances and Codex MRL (CXL) of 50 ppm on potatoes
and 15 ppm for onions are established for MH.

    No Canadian tolerances or Codex MRL are established in cran-
berries , citrus, or tobacco and no Codex MRL is established in
apples.  Therefore, no compatibility questions exist with respect
to Codex MRL.  A Canadian tolerance of 7 ppm is established for
residues of MH in apples.
                                  16

-------
    Residue Data

    The residue data reviewed in support of these tolerances,
and the data gaps are discussed below are discussed below.

     1. Available tobacco metabolism data on MH indicate that
MH is absorbed rapidly and translocated  to leaves and growing
shoots.  The major metabolite in tobacco is the glucose conju-
gate of the parent, l,2-dihydro-3,6-pyridazinedione glucoside.
Additional plant metabolism data in cranberries, onions, and
potatoes are required.

     2.  Data from a cattle feeding study indicate that residues
of MH transfer to animal tissue.  Livestock metabolism data are
not available and are required.

     3.  The available data for potatoes and dry bulb onions
indicate that the residues will not exceed the established
tolerances following registered use of SC/L K salt formula-
tion.  Additional data are required to evaluate the use
of the EC K salt formulation on potatoes and onions.  A
processing study is required on potatoes.

     4.  Available residue data on cranberries support the  tole-
rance for cranberries.  No additional data are required.

     5.  No data are available for the preharvest use of the
DEA salt of MH on potatoes and onions.  Residue data will be
required for the DEA salt for use on potatoes and onions
should any registrant comply with the data requirements which
resulted in the suspension.

     6.  NO data are available to support a nonfood classifca-
tion for the use of MH on nonbearing apples.  Data are required
and if residues are detectable on the fruit, tolerances must be
proposed and a processing study conducted to assess potential
concentration of residues in food and feed products.

     7.  Available data are insufficient to support a nonfood
use classification for use of MH on nonbearing citrus.
Residue data are required and if residues are detectable on
the fruit, tolerances must be proposed and a processing study
conducted to assess potential concentration of residues in
food and feed products.

     8.  The available data on tobacco are not sufficient to
adequately assess the exposure of man to residues of MH.
                             1

-------
Available data do indicate that MH residues of > O.Vppm are
likely to be present in tobacco and indicate the potential
for residues of hydrazine, nitrogen gas, ammonia, amines,
hydrogen gas, nitriles, and nitrogen heterocyclic compounds
following pyrolysis of MH.  Residue data are required,
pyrolysis products must be characterized, and the level of
residues occurring in smoke quantified.

    9.  Animal metabolism data are needed to show whether
tolerances for MH or its metabolites are required in animal
commodities.  If there is a need for a tolerance EPA will
also require data depicting the stability of MH or its
metabolites in animal commodities during the storage of
animal commodities.

   10.  Adequacy of analytical methodology will be determined
once requested method validation data are submitted.  If the
required animal metabolism data reveal metabolites of concern,
validated analytical methods for residue data collection and
enforcement will be required.

  Toxicology Data

      The toxicology data considered in support of the tolerances
include a chronic study in rats with a LOEL of 500 mg/kg for
renal effects, a teratology study in rabbits with a teratogenic
NOEL of 100 mg/kg, and a reproduction study in rats with a NOEL
of 750 mg/kg.  Refer to the toxicology section above for detailed
information on these studies and additional requirements.

      The data gaps in the current data base relevant to a
reference dose (PADI) are a chronic study in a nonrodent
species (dog) and a rat teratology study.  The Toxicology
Branch RfD Committee derived the reference dose of 0.5 mg/kg/
day from the LOEL of 500 mg/kg for renal dysfunction in the
rat by applying a total uncertainty factor of 1000 (a factor
of 100 for inter- and intraspecies differences and a factor
of 10 because the LOEL was used).  Existing tolerances produce
a TMRC of 0.085 mg/kg/day which occupies 17 percent of the
PADI.
                                18

-------
              IV.  REGULATORY POSITION AND RATIONALE

A.  REGULATORY POSITION AND RATIONALE

     1.  None of the criteria listed in 40 CFR 154.7 have
been exceeded for MH.  Therefore,  no referral to Special
Review is being made at this time.

         Rationale;  Based on available information, MH does
not exceed the risk criteria for adverse effects in 40 CPR
154.7.  Available data indicate that MH does not pose a risk
of serious injury to humans, avian species, or aquatic
organisms.

     2.  The Agency will not approve any significant* new
food uses of MH until additional residue chemistry data are
available to assess existing uses.

         Rationale;  It is Agency policy not to establish
significant new uses where major data gaps exist.  When
additional data are evaluated the Agency will determine
whether significant new food uses may be established.

     3.  The Agency is requiring that labeling on all EPs
require protective clothing: long sleeve shirt, long pants
and chemical resistant gloves at all times while handling,
applying, mixing, or loading this chemical.

         Rationale:  Rare teratogenic effects were observed
in test animal.  Exposure estimates for dermal exposure
were based on individuals wearing long sleeve shirts, long
pants, and chemical resistant gloves and resulted in some
margin of safety estimate of less than 100.  Refer to teratology
and exposure sections in Part III.B.  and E. for additional
information and Part IV.D. for specific wording.

     4.  The Agency is requiring that additional leaching,
aerobic/anaerobic soil metabolism, and dissipation data be
submitted to fully define the potential of MH to leach into
groundwater.

         Rationale;  The available data are insufficient to
define the potential of MH to leach and contaminate ground
water.  Refer to Part III.D. for additional information.

     5.  The Agency is requiring that additional information
be submitted on the rabbit teratology study and  that a rat
teratology study be completed within 12 months.
*"Signifleant new uses" is defined in 44 FR 27934, May 11,
 1979.  In the case of a new food or feed use, the Agency
 will consider as significant an increase in the TMRC of > 1
 percent.
                               -19-

-------
         Rationale;  A rare teratogenic effect was seen in
the rabbit teratology study; therefore, additional informa-
tion on parentage of affected animals is needed to fully
define this effect.  This information, along with the rat
teratology study, will be used to determine if additional
data on teratogenicity are needed and additional regulatory
restrictions are warranted.  Refer to teratology section of
Part III.B. for additional information.

     6.  The Agency has determined that a full battery of
toxicology studies will be necessary for the DEA salt of MH
should manufacturers comply with data requirements that re-
resulted in suspension.  Refer to Part III.B. for a detailed
listing of requirements.

         Rationale;  The Agency believes that there may be
qualitative or quantitative differences in the behavior of
DEA salt due to the DEA moiety, which itself may cause
effects not seen with other salts.

     7.  The Agency will continue to require the acceptable
limit of hydrazine occuring in technical products be <^ 1 Sppm
as required by the PD-4.

         Rationale;  The RPAR review, now called special review,
indicated that hydrazine is oncogenic and determined that
the potential risk associated with this level is very low.


     8.  The Agency has determined that product chemistry
data for all technical and MPs of MH must be submitted and
updated.  Refer to charts for details.

         Rationale;  It is Agency policy to require that all
product chemistry data for technical and MPs be updated for
each pesticide.

     9.  The Agency has determined that all end use products
containing the DEA salt of MH must be tested for nitrosamines
if and when the manufacturers comply with data requirements
that resulted in-suspension.

         Rationale;  Available data indicate that nitrosamines
may occur in products containing the DEA salt .of MH and that
some nitrosamines are known carcinogens.
                                    20

-------
    10.  The Agency has determined that reentry data or
restrictions are not required for MH at this time.

         Rationale;  Current use patterns of MH (7- to 70-day
PHI) or application to plants at early growth stages indicate
little likelihood of exposure or low exposure to workers re-
entering the field.  The placement of MH in Toxicity Category
IV for acute dermal and acute oral toxicity indicates minimal
risk to humans.

    11.  The Agency will not require labeling to protect
endangered species at this time for products containing MH.

         Rationale;  Acute toxicity data on mammals, avian
species, and aquatic species coupled with low potential for
exposure to MH indicate that endangered species are not
expected to be adversely affected by the use of MH.  Since
MH is a plant growth retardant, it could affect any endan-
gered plant species occurring in areas where MH is  applied
to tobacco cropland, citrus, apples, onions, and potatoes.
However, no endangered plant species are listed as  occurring
at these sites.  Refer to Part III.F-  for detailed information,

    12.  The Agency has determined that Tier I nontarget area
phototoxicity testing will be required for MH.

         Rationale;  No data are available on phytotoxicity
of MH to plants.  Because MH is a plant growth retardant,
there are possible effects to nontarget plants; therefore,
the data are required.

    13.  The Agency will not require additional residue data
on cranberries.

         Rationale;  The available residue data support the
established tolerances on cranberries.

    14.  The.Agency will require additional residue data on
potatoes, onions, tobacco, nonbearing citrus, and nonbearing
apples.  Refer to charts for detailed information on required
testing.

         Rationale;  Available data are not sufficient to
support the established tolerances for potatoes and onions.
Available data are not sufficient to support the nonfood
classification of nonbearing citrus and nonbearing apples.
The available data on tobacco are not sufficient to adequately
assess the exposure of man to residues of MH occurring in
tobacco.

-------
    15.  The Agency is requiring additional livestock and
plant metabolism data, and storage stability data on all
residue data previously submitted and any new residue data
requested by this document.

         Rationale:  The available plant metabolism data are
not adequate to fulfill requirements.  There are no livestock
metabolism or storage stability data available for MH.

    16.  The Agency has identified certain data that will
receive immediate review when submitted.

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

    17.  While data gaps are being filled, currently registered
MPs and EPs containing MH must be formulated  and used, subject
to the terms and conditions in the data appendices, in order to
maintain existing registrations.
         Rationale;  Under FIFRA, the Agency may choose not
to cancel or withhold registration if data are missing or are
inadequate.  See FIFRA sections 3(c)(2)(B) and 3(c)(7).
    Issuance of this Standard provides a mechanism for
identifying data needs.  These data will be reviewed and
evaluated, after which the Agency will determine if additional
regulatory changes are necessary.
                                   23

B.  CRITERIA FOR REGISTRATION

    To be registered or reregistered under this Standard,
products must contain MH or its K or DEA salts, bear required
labeling, and conform to the product composition, acute
toxicity limits, and use pattern requirements listed in this
section.

C.  ACCEPTABLE RANGES AND LIMITS

    1.  Product Composition standard

        To be registered or reregistered under this Standard,
NPs must contain MH, its K salt, or its DEA salt.  Each HP
formulation proposed for registration must be fully described
with an appropriate certification of limits, stating maximum
and minimum amounts of the active ingredient and inert ingre-
dients which are present in products as well as impurities
found at > 0.1 percent.  Technical MH used in formulating
products must not contain hydrazine greater than 15 ppm.


    2.  Acute Toxicity Limits

        The Agency will consider registration of technical
grade and MPs containing MH and salt provided that the product
labeling bears appropriate precautionary statements for the
acute toxicity category in which each product is placed.

    3.  Use Patterns

        To be registered under this Standard, MPs may be
labeled'for formulation into EPS registered for the uses
listed in Appendix B, EPA Index to Pesticide Chemicals —
Maleic Hydrazide.  The EPA Index to Pesticide Chemicals lists
all registered uses, as well as approved maximum application
rates and frequencies.

    D.  Required Labeling

        All products must bear appropriate labeling as speci-
fied in 40 CPR 162.10, PR Notices 83-2, 83-3, and below.

       No pesticide product containing maleic Hydrazide or
its salts ingredient may be released for shipment by the
registrant after June 30, 1989, unless the product bears an
amended label which complies with the requirements of this
standard.  Five (5) copies of the labeling, revised in accord-
ance with this Standard, must be submitted prior to release
for shipment.
                             -24-

-------
        Pesticide products containing maleic hydrazide or its  salts
ingredient may not be distributed, sold,  offered for sale,  (having
been so received) delivered or offered to be delivered by any  person
after July 30, 1990 unless the product bears amended labeling,
five copies of which have been submitted  to the Agency, that
complies with the requirements of this Standard.
        In addition to the above,  the following information
must appear on the labeling:

        1.  Ingredient Statement

            The ingredient statement for MPs must list  the
active ingredients:

                 Maleic hydrazide
                 1,2-dihydro-3,6-pyridazinedione
        2.  Precautionary Statements

            Statements for MPs:

                 Do not discharge effluent containing
                 this product into lakes,  streams,  ponds,
                 estuaries, oceans, or public water
                 unless this product is specifically
                 identified and addressed in the NPDES
                 permit.  Do not discharge effluent con-
                 taining this product into sewer systems
                 without previously notifying the sewer
                 treatment plant authority.  For guid-
                 ance contact your State Water Board or
                 Regional Office of the EPA.

            Statements for EPs:

                 Do not apply directly to water or
                 wetlands (swamps, bogs, marshes, and
                 potholes).  Do not contaminate water
                 when disposing of equipment washwaters.

        3.  The following statements must appear on all EPs:

                 "Wear a long-sleeve shirt, long pants, and
                 chemical resistant gloves at all times when
                 mixing, loading, handling, or applying this
                 chemical."
                                           25

             V.  PRODUCTS SUBJECT TO THIS STANDARD

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

     Products are subject to this Registration Standard as
 follows:

 A.  Manufacturing use products containing this pesticide as
 the sole active Ingredient are subject to:

      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^

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

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

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

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

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

     1.  The data requirements listed In Table A.

     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 formulator's exemptions, the
      data requirements listed In Table C.

      3.  If not eligible for the formulator's  exemption, the
      data requirements listed In Table  A and the data require-
      ments 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 formulator's  exemption,
      the date  requirements listed  in Tables  A  and  C.
 3  If  you purchase from another  producer  and use  as  the
 source of your  active  Ingredient only EPA-reglstered products,
 you are  eligible  for the formulator's exemption  for generic
 data  concerning that active ingredient (Table A) and product-
 specific  data for the  registered manufacturing use product*
 you purchase (Table 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 those
data requirements.


                        f"    27

-------
      2.   If  eligible  for the forraulator's exemption, the
      data requirements listed in Table B-2

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


        VI.   REQUIREMENT FOR SUBMISSION OF GENERIC DATA

      This portion of the Registration Standard is a notice
 issued under the authority of PIPRA sec. 3(c)(2)(B).  It
 refers to the data listed In Table A, which are required to
 be submitted by registrants to maintain in effect the regis-
 tration of products containing this active ingredient.1*

 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 PIPRA sec.
 3(c)(2)(B) (DCI  Notice).   EPA has  decided, however,  not to
 require a registrant who  qualifies  for the formulator's
 exemption (PIPRA 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  fall to take appropriate
steps to  meet the requirements or are  no  longer  In compliance
with this data requirements notice, the Agency will  consider
** Registrations granted after issuance of this Standard will
be conditioned upon submission or citation of the data listed
In this Registration Standard.


                               28

-------
  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.

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

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

 C.  What generic data must be  submitted?

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

 D.  How to comply with PCI requirements.

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

      1.  You will submit the data yourself.

     2.  You have entered into an agreement with one or more
 registrants to Jointly develop (or share in  the  cost of
developing) the data, but will not be submitting the data
yourself.  If you use this method, you must state who will
submit the data on which you will rely.  You must also provide


                                  29

-------
  EPA with documentary evidence that an agreement has  been
  formed which allows you to rely upon the  data  to be  submitted.
  Such evidence may be:   (1) your letter offering to Join in
  an agreement and the other registrant's acceptance of  your
  offer, (2)  a written statement by the parties  that an  agreement
  exists, or  (3) a written statement by the person who will be
  submitting  the data that you may rely upon  its  submission.
  The Agency  will also require adequate assurance  that the
  person whom you state will provide the data is  taking  appropriate
  steps  to secure it.   The agreement to produce the  data need
  not specify all of the terms of the final arrangement  between
  the parties or a mechanism to  resolve the terms.

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

      a.  A list of the members of  the consortium;
      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 con-
          sortium will be generating or submitting.

      The Agency will assign a number  to the consortium, which
 should be used on all data submissions by the consortium.
      3.   You have attempted to enter into an agreement  to
 Jointly  develop data, but no other registrant has accepted
 your offer.   You request that EPA not suspend your registratl
 for non-compliance with the PCI.EPA has determined  that,
 as  a general policy, it will not  suspend the registration of
 a product  when the registrant has in good faith  sought  and
 continues  to seek to enter into a data development/cost
 sharing  program, but the other registrants  developing the
 data have  refused to accept Its offer.   [If your offer  is
 accepted,  you may qualify for Option 2  above  by  entering
 Into an  agreement to supply the data.]

      In  order  to qualify for  this method, you must:

      1.  Pile  with EPA  a completed  "Certification of Attempt
to  Enter into  an Agreement  with other Registrants  for Develop
ment  of  Data"  (EPA  Form 8580-6, enclosed).

      2.  Provide  us  with a  copy of  your offer  to  the other



                                  30

-------
 registrant and proof of the other registrant's receipt of your
 offer (such as a certified mall 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 PIPRA sec.
      3(c)(2)(B) In the [name of active Ingredient] Registration
      Standard upon terms to be agreed or falling agreement
      to be bound by binding arbitration as provided by PIPRA
      section 3(c)(2)(B)(lll).

 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 falls 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,

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

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

     6.  You request voluntary cancellation of the registration
of your product's) for which the data are needed^
                               31

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

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

     As noted herein, these EPA 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-W-M650).

     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.

 P.  Procedures for requesting a change in testing protocol.

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

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


 G.  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.  Any request for a time
                            32

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

      EPA will view failure to request an extension before
 the data submission response deadline as a waiver of any
 future claim that there was insufficient time to submit the
 data.  While EPA considers your request, you must strive to
 meet the deadline for submitting the data.

      The extension request should state the reasons why you
 believe that an extension Is necessary and the steps you
 have taken to meet the testing deadline.  Time extensions
 normally will not be granted due to problems with laboratory
 capacity or adequacy of funding, since the Agency believes
 that with proper planning these can be overcome.

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

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

     All data submitted in response to this Notice must comply
 with EPA requirements  regarding  the  reporting of  data, Including
 the manner  of reporting,  the  completeness of results,  and the
 adequacy  of  any  required  supporting  (or  raw) data,  including,
 but not limited  to,  requirements  referenced or Included in
 this  Notice  or contained  in PR Notice 86-5 (Issued  July 29,
 1986).  All  studies must  be submitted in the form of a final
 report; a -preliminary  report will  not  be  considered  to fulfill
 the submission requirement.

 I.  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  is  not
 consistent with the Act.  Accordingly, the  Agency does  not
 anticipate granting permission to  sell or distribute existing
 stocks of suspended product except in  rare  circumstances.
 If you believe that your product will  be  suspended or  cancelled
 and that an existing stocks provision  should be granted,  you
have the burden of clearly demonstrating to  EPA that granting
                                33

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

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

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


    VII. REQUIREMENT FOR SUBMISSION OP 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 B-2.   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 require-
 ments,  you  must follow the same procedures as for  generic data.
 See Section VI.D,  E, P, and  Q.  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  require-
ments for your products will result in suspension of the
product's registration.
                             34

-------
     VIII.   REQUIREMENT FOR SUBMISSION OP REVISED LABELING

      PIPRA 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
 HO CPR 156.10 (see Appendix II - LABELING and SUMMARY).  In
 addition,  labeling requirements specific to products containing
 this  pesticide are specified In Section IV.D of this Registra-
 tion  Standard.  Applications submitted In response to this
 notice must  Include draft labeling for Agency review.

      If  you  fall 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 or suspend the
 registration of your product  under PIPRA sec. 6.


               IX.  INSTRUCTIONS FOR SUBMISSION

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

                            TGUIDE-1

                        GUIDE TO TABLES

      Tables A, B, and B-2 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 B-2 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 CPR Part 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 Port  Royal Road,  Springfield, VA 22161.

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

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

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

 3.   Use pattern  (Column 3)-  This  column indicates  the use
patterns to which the data requirement applies.  Use patterns
are  the same  as those given  in 40 CPR Part 158.  The following
letter designations are used for the  given use patterns:
     A
     B
     C
     D
     E
     P
     G
Terrestrial, food
Terrestrial, non-food
Aquatic, food
Aquatic, non-food
Greenhouse, food
Greenhouse, non-food
Forestry
     H « Domestic outdoor
     I - Indoor

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

                            TGUIDE-2

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

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

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

      NO - EPA either possesses no data which are sufficient
      to fulfill the data requirement, or the data which EPA
      does possess  are flawed scientifically In a manner that
      cannot be remedied by clarification or additional Infor-
      mation.

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

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

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

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

  \J  Data must be submitted within the  indicated timeframe, based on the  issue date of this Guidance Document.

  2/  The same chemical  identity data are required as under Part  158 Subpart C- Product Chemistry, with emphasis on
      impurities that could constitute residue problems.  Refer to Product Chemistry Data Requirements tables.

  3/  Studies must be submitted depicting the distribution and the metabolism of  [ring-l^c]maleic hydrazide (acid) in
      cranberries, onions, and potatoes  and  [ethyl-'^C]diethanolamine salt of maleic hydrazide in onions and potatoes
      following foliar broadcast applications at rates  sufficiently high to permit complete characterization of all
       '^C-residues.  These studies must  include specific protocols to characterize and quantify the impurity hydrazine.
      Analyses must  include hydrolysis and reextraction of plant  samples and aqueous fractions to determine conjugated
      '^C-residues of maleic hydrazide.  Representative samples from these studies must also be analyzed using all
      current and proposed enforcement methods (including all FDA Miltiresidue Protocols [I-IV], Method I in PAM Vol.
      II and the modification of Lane [MRID  No. 00106983]) to ascertain that these methods are capable of adequately
      recovering and quantifying all residues of concern.

  4/  Metabolism studies using ruminants and poultry must be submitted.  Animals must be dosed for at least 3 days
      with  [ring-14c]maleic hydrazide (acid) at a level high enough to permit identification and quantification
      of the ^C-residues.  These studies must also include specific protocols to characterize and quantify
      the impurity hydrazine.  If necessary, hydrolysis and reextraction of samples and aqueous fractions must be
      used  to release  ^-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
       (including all FDA Mult ires idue Protocols [I-IV], and Method I in PAM Vol. II) to ascertain that the methods
      are capable of adequately recovering and quantifying all residues of concern.  [If the required plant metabolism
      studies using  the  [ethyl-'^Cjdiethanolamine salt  of maleic  hydrazide reveal that diethanolamine per se and/or
      the diethanolamine salt will occur as  a residue in or on potatoes, metabolism studies in ruminants and poultry are
      also  required  using  ['^C]diethanolamine and/or the [ethyl-'^C]diethanolamine salt.]
   V   Data depicting the nature of maleic hydrazide residues  in swine are also required if the required metabolism
       studies with ruminants  and  poultry reveal  that  the metabolism of maleic hydrazide in these animals differs
     •  from that  in rats.

   6/   We have  required that Mil tires idue Methods I-IV, Method I in PAM Vol. II, and the modification of Lane
       (MRID No.  00106983)  be  tested in conjunction with the required plant and animal metabolism studies.  Protocols
       for Methods I, II,  III, and IV  are available from the National Technical Information Service under Order
js*     No. PB 203734/AS.

y  If the required animal metabolism data reveal metabolites, analytical methods for data collection
    and tolerance enforcement will be required.

8/  Samples bearing measurable field-weathered residues or fortified samples must be analyzed immediately after
    harvest or fortification and stored under conditions and for intervals equivalent to those under and for
    which samples in the following previously submitted studies were stored:  potatoes (MRID Nos. 00086764 and
    00121603), onions (00121605), and cranberries (00100749 and 00101298).  Also, all residue data requested in
    this Standard must 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 must be submitted depicting maleic hydrazide residues in or on potatoes following treatment
    with EC and SC/L diethanolamine salt formulations and EC potassium salt formulations at 3 Ib ai/A.  Each salt
    and formulation class must be reflected in a separate test.  Application must be made to uniformly flowering
    potatoes 7 days following blossom drop and to irrigated potatoes 2 to 3 weeks following full bloom when tubers
    are 1 inch in diameter.  Tests must be conducted in CA (6%), ID (25%), ME (7%), MI (4%)/WI (6%), and OR (7%)/WA
    (15%) since these States collectively produced ca. 70% of the 1985 U.S. potato crop (Agricultural Statistics
    1986, p. 164).  A PHI must be proposed and reflected in the submitted data.  The registrant must also propose a
    PHI for the potassium salt SC/L and SC/S labels and amend the labels to permit only a single application/year.

10/ Data must be submitted depicting maleic hydrazide residues in chips, granules, and wet and dry peel,
    processed from potatoes bearing measurable weathered residues.  If residues concentrate in peel or granules,
    appropriate feed/food additive tolerances must be proposed.  The established food additive tolerance for
    chips will be reassessed following evaluation of these data.

11 / Data must be submitted depicting maleic hydrazide residue in or on dry bulb onions following application
    of a diethanolamine salt of an EC and SC/L formulation and potassium salt of an EC formulation, in

  12/ Data must be submitted depicting maleic hydrazlde residues in or on apples treated with the 3 Ib/gal
      SC/L diethanolamine salt formulation at 6 Ib ae/A in a nonbearing year.  Fruit must be harvested at the shortest
      possible interval following registered use and should include tests using early maturing varieties.  Tests
      must be conducted in CA (8%), MI (14%), NY (14%)/PA (7%), and WA (26%) because these States produced ca. 70%
      of the 1985 U.S. apple crop (Agricultural Statistics 1986, p. 186).  Upon receipt of the requsted data, the
      appropriateness of the nonfood use classical:ion will be assessed.  If residues are detectable in or on fruit,
      a tolerance must be proposed and a processing study conducted to assess potential concentration of residues
      in food and feed products (wet and dry pomace and juice).

  13/ Data must be submitted depicting maleic hydrazide residues in or on citrus fruits (oranges and
      grapefruit) treated twice (November 15 and 8 weeks later) to runoff with the EC and SC/L potassium and
      diethanolamin salt formulations, in separate tests, at 1.5 Ib ae/100 gal water in a nonbearing year.  Fruit
      must be harvested at the shortest possible interval following registered use and should include tests using
      early maturing varieties.  Tests must be conducted in Florida.  The registrant must propose a maximum rate or
      volume/A, which must be reflected in the submitted data.  Upon receipt of the requested data, the appropriateness
      of the nonfood use classification will be assessed.  If residues are detectable in or on fruit, a tolerance
      must be proposed and a processing study conducted to assess potential concentration of residues in food and
      feed products (dried pulp, oil, molasses, juice).

  14/ Data must be submitted depicting maleic hydrazide residues in or on green freshly harvested and
      cured or dry tobacco leaves following foliar broadcast application (i) after topping to plants in full
      flower with the EC and SC/L diethanolamine formulation (in separate tests) at 3 Ib ae/A; and (ii) 7
      days prior to harvest using an SC/L potassium salt formulation at 4.5 Ib ae/A to dark-fired tobacco
      varieties.  The residues data must include decline decline studies at regular intervals following
      application of diethanolamine salts to tobacco.  Tests must be conducted in KY (28%), NC (37%), and TN
      (8%), States which produced ca. 73% of the 1985 U.S.  tobacco crop (Agricultural Statistics 1986, p. 93).

  15/ Pyrolysis products derived from the active ingredient must be characterized and the level of the residue in
      smoke must be quantified.  ([^Jroaleic hydrazide must be used for identification of pyrolysis products.)

  16/ Following receipt and evaluation of the required plant and animal metabolism data and residue data for
  ..   potatoes (feed items - cull potatoes and processed potato waste), specific data requirements for livestock
  ,-   feeding studies will be determined.

 \J   Data must be submitted within the indicated timefraroe, based on the issue date of this Guidance Document.

 2/   The sane chemical identity data are required as under Part 158 Subpart C- Product Chemistry, with emphasis on
     impurities that could constitute residue problems.  Refer to Product Chemistry Data Requirements tables.

 3/  Studies must be submitted depicting the distribution and the metabolism of [ring-14C]maleic hydrazide (acid) in
     cranberries, onions, and potatoes and [ethyl-1^C]diethanolamine salt of maleic hydrazide in onions and potatoes
     following foliar broadcast applications at rates sufficiently high to permit complete characterization of all
      '^C-residues.  These studies must include specific protocols to characterize and quantify the impurity hydrazine.
     Analyses must include hydrolysis and reextraction of plant samples and aqueous fractions to determine conjugated
      '^-residues of maleic hydrazide.  Representative samples from these studies must also be analyzed using all
     current and proposed enforcement methods (including all Fltt Multiresidue Protocols [I-IV], Method I in PAM Vol.
      II and the modification of Lane [MRID No. 00106983]) to ascertain that these methods are capable of adequately
     recovering and quantifying all residues of concern.

 4/  Metabolism studies using ruminants and poultry must be submitted.  Animals must be dosed for at least 3 days
     with  [ring-t^cjmaleic hydrazide (acid) at a level high enough to permit identification and quantification
     of the ^C-residues.  These studies must also include specific protocols to characterize and quantify
      the Impurity hydrazine.  If necessary, hydrolysis and reextraction of samples and aqueous fractions must be
      used  to release I^C-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
      (including all FTtt Multiresidue Protocols [I-IV], and Method I in PAM Vol. II) to ascertain that the methods
      are capable of adequately recovering and quantifying all residues of concern.  [If the required plant metabolism
      studies using the [ethyl-1 ^CJdiethanolanine salt of maleic hydrazide reveal that dtethanolanlne per se and/or
      the diethanolamine salt will occur as a residue in or on potatoes, metabolism studies in ruminants and poultry are
      also  required using M^CJdiethanolamine and/or the [ethyl-I^C]diethanolamine salt.]

 5/   Data  depicting the nature of maleic hydrazide residues in swine are also required if the required metabolism
      studies with ruminants and poultry reveal that the metabolism of maleic hydrazide in these animals differs
      from  that in rats.

~-6/   We have required that Multiresidue Methods I-IV, Method I in PAM Vol. II, and the modification of Lane
 ~~    (MRID No. 00106983) be tested in conjunction with the required plant and animal metabolism studies.  Protocols
      for Methods I, II. Ill, and IV are available from the National Technical Information Service under Order
s*     No. PB 203734/AS.

7/  If the required animal metabolism data reveal metabolites, analytical methods for data collection
    and tolerance enforcement will be required.

8/  Samples bearing measurable field-weathered residues or fortified samples must be analyzed immediately after
    harvest or fortification and stored under conditions and for intervals equivalent to those under and for
    which samples in the following previously submitted studies were stored:  potatoes (MRID Nos. 00086764 and
    00121603), onions (00121605), and cranberries (00100749 and 00101298).  Also, all residue data requested in
    this Standard must 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 must be submitted depicting maleic hydrazide residues in or on potatoes following treatment
    with EC and SC/L diethanolamine salt formulations and EC potassium salt formulations at 3 Ib ai/A.  Each salt
    and formulation class must be reflected in a separate test.  Application must be made to uniformly flowering
    potatoes 7 days following blossom drop and to irrigated potatoes 2 to 3 weeks following full bloom when tubers
    are 1 inch in diameter.  Tests must be conducted in CA (6%), ID (25%), ME (7%), MI (4%)/WI (6%), and OR (7%)/V*V
    (15%) since these States collectively produced ca. 70% of the 1985 U.S. potato crop (Agricultural Statistics
    1986, p. 164).  A PHI must be proposed and reflected in the submitted data.  The registrant must also propose a
    PHI for the potassium salt SC/L and SC/S labels and amend the labels to permit only a single application/year.

10/ Data must be submitted depicting maleic hydrazide residues in chips, granules, and wet and dry peel,
    processed from potatoes bearing measurable weathered residues.  If residues concentrate in peel or granules,
    appropriate feed/food additive tolerances must be proposed.  The established food additive tolerance for
    chips will be reassessed following evaluation of these data.

11 / Data must be submitted depicting maleic hydrazide residue in or on dry bulb onions following application
    of a diethanolamine salt of an EC and SC/L formulation and potassium salt of an EC formulation, in
    separate tests, at 2 pounds acid equivalent per acre (Ib ae/A).  Tests must be conducted in CA (27%), CO (12%),
    ID (8%), MI (6%), NY (9%), OR (15%)/ WA (5%), and TX (9%) since these States collectively produced ca. 74% of
    the 1985 U.S. storage onion crop (Agricultural Statistics 1986, p. 161).  A PHI must be proposed and reflected
    in the submitted data.  The registrant must also propose a PHI for the potassium salt SC/S and SC/L labels and

  12/ Data must be submitted depicting maleic hydrazide residues in or on apples treated with the 3 Ib/gal
      SC/L diethanolamine salt formulation at 6 Ib ae/A in a nonbearing year.  Fruit must be harvested at the shortest
      possible interval following registered use and should include tests using early maturing varieties.  Tests
      must be conducted in GA (8%), MI (14%), NY (14%)/PA (7%), and WA (26%) because these States produced ca. 70%
      of the 1985 U.S. apple crop (Agricultural Statistics 1986, p. 186).  Upon receipt of the requated data, the
      appropriateness of the nonfood use classication will be assessed.  If residues are detectable in or on fruit,
      a tolerance must be proposed and a processing study conducted to assess potential concentration of residues
      ih food and feed products (wet and dry pomace and juice).

  13/ Data must be submitted depicting maleic hydrazide residues in or on citrus fruits (oranges and
      grapefruit) treated twice (November 15 and 8 weeks later) to runoff with the EC and SC/L potassium and
      diethanolanin salt formulations, in separate tests, at 1.5 Ib ae/100 gal water in a nonbearing year.  Fruit
      must be harvested at the shortest possible interval following registered use and should include tests using
      early maturing varieties.  Tests must be conducted in Florida.  The registrant must propose a maximum rate or
      volume/A, which must be reflected in the submitted data.  Upon receipt of the requested data, die appropriateness
      of the nonfood use classification will be assessed.  If residues are detectable in or on fruit, a tolerance
      must be proposed and a processing study conducted to assess potential concentration of residues in food and
      feed products (dried pulp, oil, molasses, juice).

  14/ Data must be submitted depicting maleic hydrazide residues in or on green freshly harvested and
      cured or dry tobacco leaves following foliar broadcast application (i) after topping to plants in full
      flower with the EC and SC/L diethanolamine formulation (in separate tests) at 3 Ib ae/A; and (ii) 7
      days prior to harvest using an SC/L potassium salt formulation at 4.5 Ib ae/A to dark-fired tobacco
      varieties.  The residues data must include decline decline studies at regular intervals following
      application of diethanolamine salts to tobacco.  Tests must be conducted in KY (28%), NC (37%), and TN
       (8%), States which produced ca. 73% of the 1985 U.S.  tobacco crop (Agricultural Statistics 1986, p. 93).

  15/ Pyrolysis products derived from the active ingredient must be characterized and the level of die residue in
      smoke must be quantified.  ([1^C]maleic hydrazide must be used for identification of pyrolysis products.)

  16/ Following receipt and evaluation of the required plant and animal metabolism data and residue data for
  ._   potatoes (feed items - cull potatoes and processed potato waste), specific data requirements for livestock
  ,,    feeding studies will be determined.

1_/   Data  must be submitted within.the  indicated timeframes,  based on the issue date of  this guidance document.
2/   An absorption spectrum of maleic hydrazide is required.
3/   The requirement for data is reserved pending the results of an acceptable acute inhalation study.
A/   This  study is not required to support the current use pattern, which does not  include aquatic,  forestry,
     or aquatic impact uses.
5/   This  study is not required to support the current use pattern, which does not  include aquatic or aquatic
     impact uses.
6/   This  study is partially acceptable:  An imaged adsorption/desorption study using  five soils was acceptable;
     however, an aged soil column study using two soils (one sand plus one representative of intended use area)
     is required.
7/   The requirement for the study is reserved pending results of an acceptable acute  inhalation study.
&/   The requirement for the study is reserved pending the results of the laboratory volatility study.
9/   This study is not required because the current use pattern does not include forestry uses.
JO/ There are no current registered combination or tank mixes for maleic hydrazide.

        for  wheat or another small grain.

    13/ The requirement  is reserved pending results rotational interval of the confined study or wheat.

    14/ This study is not required because the reviewed octanol/water partition coefficient study (Cable, 00163301)
        gave a value of  < 0.6, thereby  indicating a very low potential for maleic hydrazide to bioaccumulate in fish.

     Item 8C.  PHYSICAL OR  CHEMICAL HAZARD - PLAMMABILITY
 Precautionary statements  relating to flaramabllity 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  flammablllty statements.

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

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

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

     If  you do not believe that your product should be classified
 for  restricted use, you must submit  any information and
 rationale with your application for  rereglstration.  During
the  Agency's review of your application, your proposed classi-
fication determination will be evaluated in accordance with
the provisions of Part 152, Subpart  I.  You will be notified
of the Agency's classification decision.

      Classification  Labeling Requirements

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

      1.  All uses  restricted.

          a.   The statement "Restricted Use Pesticide" must
      appear  at the top  of  the front panel of the label.  The
      statement must  be  set in type of the same minimum size
      as required for human hazard signal word (see table in 40
      CFR 156.10(h)(1)(iv)

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

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

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

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

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

     Item 9B.   MISUSE STATEMENT - All products must bear  the
misuse  statement.  "It is a violation of Federal law  to use
 this  product in a  manner inconsistent with  its  labeling."
This  statement appears  at  the beginning of  the directions
for use,  directly  beneath  the heading  of  that  section.
                                   82

                           SUMMARY-5

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

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

     Item IOC.   DIRECTIONS FOR USE  - Directions for use must
 be  stated  in terms which can be easily read and understood by
 the average  person likely to use or to supervise the use of
 the pesticide.  When followed,  directions must be adequate to
 protect  the  public from fraud and from personal injury and to
 prevent  unreasonable adverse effects on the environment.
 [40 CPR  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.
                                 83

                            BIBGUIDE-1

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

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

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

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

                        BIBGUIDE-2

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

b.  Document Date.  When the date appears as four digits
    with no question narks, the Agency took it directly
    from the document.  When a four-digit date is followed
    by a question mark, the bibliographer deduced che
    date from evidence in che 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  fol-
    lowing elements describing the earliest known submission:

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

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

    (3)  Submitter.  The third element is the submitter.
         following the phrase "submitted by."  When
         authorship is defaulted to the submitter,  this
         element is omitted.

    (4)  Volume Identification (Accession Numbers).  The
         final  element in the trailing parentheses
         identifies the EPA accession  number of the volume
         in which the original submission of the study
         appears.  The six-digit accession  number  follows
         the symbol "CDL," standing for  "Company Data
         Library."  This accession number  is in turn
         followed by an alphabetic suffix which shows the
         relative position of the study  within  the volume.
         For example, within accession number 123456, the
         first  study would be 123456-A;  the  second. 123456-
         B;  the 26th, 123456-Z; and the  27th. 123456-AA.

             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.

                          GENERIC DATA EXEMPTION STATEMENT

 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 Confidental 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 No.  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	 .

     (4) My firm will apply for an amendment to the registration prior to changing
 the source of the active ingredient in our product to one that is not registered
 and purchased.

     (5)  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).

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

 Registrant's authorized representative:
                                               (Signature)

Dated:
