                        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
 roan and the environment.

      The  detailed  scientific review, which is not  contained
 in this document,  but is available  upon  request1,  focuses on
 the pesticide active ingredient.  The scientific review
 primarily discusses the Agency's  evaluation of  and conclusions
 from available data in its  files  pertaining to  the pesticide
 active ingredient.  However, during the  review  of  these data
 the Agency is also looking  for potential hazards that  may be
 associated with the end use products that contain  the  active
 ingredient.  The Agency will apply  the provisions  of this
 Registration  Standard to end use  products if necessary to
 protect man and the environment.
 *The scientific reviews may be obtained from the Information
  Services  Section,  Program Management and Support Division
  (TS-757C),  EPA,  401  M St., SW, Washington,  D.C.  20460.

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

      1.   Submission of data in support of product registration;

      2.   Modification of product labels;          ' •

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

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

      5.   Modification of uses or formulation types; or

      6.   Specification of packaging limitations.

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

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

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

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

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

                    III.  AGENCY ASSESSMENT

 A.   SUMMARY
 Based on the  review  of  the  available data, the Agency has
 reached  the conclusions set forth  in this Standard.  A summary
 of  those conclusions follows.  A more detailed discussion is
 contained in  the  remainder  of  this chapter.

 1.   The  major hazard concern is the potential for acute
     toxicity  to humans  and  to  fish and wildlife from exposure
     to formulated fenamiphos products.  Technical fenamiphos
     is acutely toxic to laboratory animals, Toxicity
     Category  I, by the  oral, dermal, and inhalation routes
     of exposure.   It is also very highly toxic to birds as
     well as to cold  and warm water fish.  Fenamiphos has
     also been shown  to  cause reproductive impairment in
     waterfowl and upland game  birds.  Field kills (birds and
     mammals)  have occured in many  instances in areas after
     fenamiphos application.  All uses of fenamiphos exceed
     restricted use criteria for fish and wildlife; 1/5
     the  acute oral LDjQ for mammals, 1/5 the subacute dietary
I    LCso for  birds,  and 1/10 the acute 1X50 for aquatic
     organisms.  The  Agency  has concluded that the risks to
     fish and  wildlife associated with unrestricted use of
     fenamiphos constitute unreasonable adverse effects;
     therefore, all products are being restricted.

 2.   Studies using both  the  granular and spray formulations
     of fenamiphos according to label directions have shown
     some avian and mammalian mortality.  These studies
     suggest that  soil incorporation and/or irrigation
     immediately following application will reduce hazards
     to non-target avian and mammalian species.  A terrestrial
     field study is necessary to determine if the hazards
     indicated by  laboratory and simulated field studies are
     below levels  of  concern for mammalian and avian species
     under actual  use conditions.

 3.   Both aerial application of fenamiphos as well as runoff
     exposure  pose a  potential  hazard to fish species indigenous
     to small  lakes,  ponds,  and streams.  Aquatic contamination
     from aerial application could occur when fenamiphos is
     applied as a  broadcast  spray to crops irrigated by
     interconnected waterways and could result in residues
     that exceed LCso values.   Estimated environmental
     concentrations for  runoff  also exceed LCso values.
     Simulated and actual field testing of aquatic organisms
     is required to assess potential exposure and toxicity to
     aquatic organisms.

-------
4.  Fenamiphos is not oncogenic in rats or mice.   The dietary
    cholinesterase no-observable-effect level (NOEL)  for
    fenamiphos is 1.0 ppm for both rodents and non-rodents.
    No adverse reproductive effects were observed in  a
    3-generation rat reproductive study.  Evidence regarding
    developmental effects resulting from fenamiphos are
    inconclusive.  Teratology studies in the rat  and  rabbit
    are required.  Fenamiphos was negative for mutagenic
    effects in the test systems assayed.

5.  Many of the tolerances are supported by residue data.
    However, data are required for garlic, soybeans,  grapes,
    bananas, cocoa beans, cottonseed, peanuts, pineapple,
    tobacco, and nonbearing orchard crops.  The adequacy of
    tolerances for residues in animal commodities will be
    assessed after required animal metabolism data and
    residue data for feed items are submitted and reviewed.
    A provisional acceptable daily (PADI) intake  has  been
    set at 0.00025 mg/kg/day. This is based on the
    no-observable effect level (NOEL) from a 2-year dog
    feeding study of 0.025 mg/kg/day (1 ppm) for  cholin-
    esterase inhibition, and an uncertainty factor of 100
    which accounts for the lack of an acceptable  teratology
    study.  The Theoretical Maximum Residue Contribution
    (TMRC ) for the U.S. population average based  on anticipated
    residues and percent crop treated,  is 0.00011 mg/kg/day
    which corresponds to 42% of the PADI.  It is  possible
    that resolution of the teratology data gap will allow for
    a lower uncertainty factor which will result  in a higher
    ADI and consequently a lower percentage of the ADI
    occupied by the TMRC.

    6.  Except for hydrolysis and photodegradation studies
    in water, the available data are insufficient to  fully
    assess the environmental fate of fenamiphos.
    Additional enviromental fate data are required.
    The potential for fenamiphos to reach ground  water
    cannot be assessed until the acceptable environmental
    fate studies are received and reviewed by the Agency.

As a result of this review, the Agency has identified data
necessary to further evaluate the environmental and human
risks associated with the use. of fenamiphos.  These data
must be submitted in order to maintain registrations  of
products or register new products containing fenamiphos.  A
summary of these data gaps appears in Table 1.  Note  that
this is only a summary and complete details can be obtained
by referring to the tables in Appendix I.

-------
                              8
The Agency has determined that certain label restrictions
or revisions are necessary in order for fenamiphos products
to remain in compliance with FIFRA.  These include:
       Restricted Use Classification
       Environmental Hazards Precautions
       Endangered Species
       Reentry Interval
       Protective Clothing

Chapter IV, Section D, contains the specific wording for
each of the labeling statements and identifies the products
to which each labeling statement applies.

Chapter IV, Section A, Regulatory Position and Rationale,
discusses the Agency's position regarding fenamiphos.

B.  PRELIMINARY RISK ASSESSMENT

    Toxicological Studies - FenamiphQS.  Several data gaps
    exist for fenamiphos so definitive conclusions cannot be
    reached for certain toxicological effects until additional
    data is received and reviewed.  The following assessment
    is based on the data available.

    1.  Acute Toxicity and Irri_tation Studies.  Adequate
        acute studies exist to define the acute toxicity of
        fenamiphos products.   Technical fenamiphos is acutely
        toxic, (Toxicity Category I), by the oral route
        (LD5Q 2.7 mg/kg), dermal route (1*050 178.8 mg/kg),
        and inhalation route  (LCso 0.1 mg/L) of exposure.

        Technical fenamiphos  is slightly irritating to the
        eye (Toxicity Category III)  but is not a dermal
        irritant (Toxicity Category  IV).  Technical
        fenamiphos is not a dermal sensitizer or a
        delayed neurotoxicant.

        No further acute toxicity studies are required at
        this time.

    2.   S_ubchrqni_c_ Testing,

        Oral (Rodent,, N on-Rodent). Studies:

        In a 90-day feeding study* fenamiphos was fed to
        Wistar rats at levels of 0,  4, 8, 16, and 32 ppm for
        90 days.   There was no mortality at the levels fed
        but cholinergic signs of toxicity were observed in
        animals at the 32 ppm level.  A dose-related decrease
        in plasma cholinesterase values by 34 to 44 percent
        was reported in female rats  for dietary levels of 8,
        16, and 32 ppm.  Maximum cholinesterase inhibition
        was observed within the first week of the study
        for males and by the  eighth  week for female rats.
        Erythrocyte cholinesterase inhibition was observed
        for animals fed dietary levels of 16 and 32 ppm.
        The no-observable-effect level (NOEL) for
        cholinesterase inhibition is 4 ppm.  No significant
        difference in male or female relative organ weights
        between the control and test groups was reported.
        No histopathological  findings were reported as being
        attributed to the test material.

-------
                         11
In a second subchronic study , Beagle dogs were
fed dietary levels of 0, 1, 2, and 5 ppm fenaroiphos
for 90 days.  A decrease in body weight gain was
reported for females at the highest dose level
(5 ppm).  Plasma cholinesterase was inhibited by
more than 20 percent for dietary levels of 2 and
5 ppm with a greater than 20 percent decrease in
erythrocyte cholinesterase activity reported for
the 5 ppm level.  Cholinesterase inhibition was
dose related and occurred during the fourth week
of the study.  The NOEL for cholinesterase'
inhibition is 1.0 ppm.

No further subchronic oral studies are required
at this time.

Dermal Studies,.  An aqueous formulation of 89.8%
technical fenamiphos was applied to New Zealand
rabbits at 0, 0.5, 2.5 and 10 mg/kg body weight
for a 6 hour exposure 5 days a week for 3 weeks.
Half of the animals were abraded.  A decrease in
body weight gain was observed for both sexes at the
highest dose tested, 10 mg/kg day.  A decrease in
alanine aminotransf erase was reported at the 2.5 and
10.0 mg /kg/day levels of 33 and 20 percent,
respectively, in female rabbits.  Plasma and brain
cholinesterase were depressed at 2.5 and  - —
10 mg/kg/day in female rabbits.  Plasma and
erythrocyte cholinesterase in male rabbits and
erythrocyte cholinesterase in female rabbits were
decreased at 10 mg/kg/day.  The NOEL for plasma,
erythrocyte or brain cholinesterase inhibition is
0.5 mg/kg/day.

No further subchronic dermal studies are required
at this time.

There are no 90-day subchronic dermal toxicity studies
on f enamiphos.  The registered uses of f enamiphos do
not require this study.

           .Studies.  A 21-day inhalation study is
                  '
 ^          .
required because r'enamiphos is registered for use
on tobacco.

Ne_urQtoxi_c_ity_ .S_tu_di_es_.  There are no subchronic
neu r otox i city studies on fenamiphos.  Fenamiphos was
negative for neurotoxicity in the acute delayed
neurotoxicity study and is without evidence of
delayed neurotoxicity in other mammalian species.
Therefore, a subchronic neurotoxicity study is not
required.

3-  Chronic Testing

    Chronic .Tpxicity Studies.   There  are  sufficient
    data available to 'deffi ne the  long term effects
    of fenamiphos.

    Fenamiphos was fed  to Fischer 344 rats (50/sex/group)
    for 2 years at dietary  levels of  0, 2,  10,  and 50
    ppm.  A decrease in body weight gain  was  reported
    for the 50 ppm level accompanied  by a transient
    decrease in food consumption  for  female rats  of  the
    high dietary level  (50  ppm).   Of  the  organs weighed,
    at the termination  of the study a decrease  in absolute
    liver weight and an increase  in absolute  and  relative
    lung weights were reported for the 50 ppm level.  A
    dose related decrease in plasma and erythrocyte
    cholinesterase activity was observed  for  males and
    females of all three dietary  levels by the  sixth
    week of the study.   Over the  duration of  the  study
    the plasma cholinesterase values  at 2 ppm were depressed
    by 6 to 38 percent  in males and 22 to 42  percent in
    females, while erythrocyte cholinesterase was depressed
    by 2 to 7 percent in males and 3  to 11  percent in
    females.  Brain cholinesterase activity for males at
    the low-dose level  (2 ppm) was depressed  by 5 percent
    with the female values  comparable to  the  control
    cholinesterase values.   The cholinesterase  NOEL
    for this study is less  than 2 ppm.  However,
    in a concurrent subchronic rat feeding  study  dietary
    levels of 0.36,  0.6 and 1.0 ppm were  fed  to male and
    female rats for 90  days without effect  on plasma,
    erythrocyte,  or brain cholinesterase  values.  The
    rat cholinesterase  NOEL for fenamiphos  is 1.0 ppm.
    The systemic NOEL from  the two year rat study is
    10 ppm.

    No dose-related increase in neoplastic  and  non-
    nepplastic histopathological  lesions  was  observed
    from feeding dietary levels of 2,  10,  and 50  ppm to
    male and female rats for 2 years.

    Fenamiphos was fed  to 8 month old Beagle  dogs (four/
    sex/group) at dietary levels  of 0, 0.5, 1.0,  2.0,
    5.0,  and 10 ppm for 2 years.   No  effects  were observed
    for the following parameters  at levels  up to  and
    including 10 ppm:   appearance, growth rate, food
    consumption,  mortality,  hematology, and clinical
    chemistry.   No gross (including organ weights) or
    histopathological changes  were attributed to  dietary
    levels of fenamiphos.   Plasma cholinesterase  activity

-------
                          13
was depressed at the 2, 5, and 10 ppm dietary levels
with erythrocyte cholinesterase activity depressed
at the 5 and 10 ppm levels in both sexes.  Brain
cholinesterase values were not determined.

     In a subsequent subchronic feeding study
dietary levels of 0, 0.6, 1.0, and 1.7 ppm were fed
to 4 month old Beagle dogs (4/sex/group) for 100
days.  Plasma cholinesterase activity was depressed
by 28 to 35 percent only in males fed the 1.7 ppm
level.  Erythrocyte and brain cholinestera.se activity
were not affected at any of the dietary levels tested.

     The cholinesterase NOEL based on a 2-year dog
feeding study is 1.0 ppm with the lowest effect
level for cholinesterase inhibition determined to be
2 ppm.  The systemic NOEL based on a 2-year dog
feeding study is 10 ppm, the highest level fed.

No further chronic toxicity studies are required at
this time.

Oncogenicity>  There are sufficient data available
to determine that fenamiphos is not oncogenic in
rats or mice.

Fischer 344 rats (50/sex/group) were fed dietary
levels of 0, 2, 10, and 50 ppm for 2 years.  No
dose-related increase in neoplastic or nonneoplastic
histopathological lesions was observed as compared
to the control animals.

In another study, CD outbred strain albino mice
(50/sex/group) were fed dietary levels of 0, 2, 10
and 50 ppm for eighteen months.  Statistically
significant increases in mean relative brain weight
and decreased body weight were reported in females
fed 50 ppm.  Fenamiphos was not shown to be
oncogenic.

No further oncogenicity studies are required at
this time.

Teratology.  Sufficient data are not available to
determine the teratogenicity of fenamiphos in
rabbits.

New Zealand rabbits (20 females/group) were administered

-------
                      14
88.8% fenamiphos orally in corn oil at doses of 0, 0.1,
0.3, and 1.0 rag/kg body weight from days 6 to 18 of
gestation.  Maternal toxicity was observed at the
0.3 and 1.0 mg/kg dosage levels consisting of a
decrease in mean body weight gain accompanied by a
90 and 88 percent survival, respectively.  Liver
lesions were observed at the 1.0 mg/kg level.  Mean
fetal weight was slightly depressed at 1.0 mg/kg.
One dam at 0.3 mg/kg aborted one dead pup on day 25.
Two dams at 1.0 mg/kg aborted on days 26 and 28 with
eight dead pups and seven late resorptions, respec-
tively.  In addition, one dead fetus was observed in
each of two litters at the high-dose during Cesarean
section.  A significant increase in the incidence of
chain-fused sternebrae was noted at 1.0 mg/kg, with
a finding of five fetuses in three litters.  There
was also one fetus in one litter at 0.3 mg/kg with a
finding of chain-fused sternebrae.  Fenamiphos caused
an increased incidence in a minor anomaly (left
carotid artery arising from the innominate) at all
three dose levels, which was greater than the
spontaneous occurrence in the historical controls.
Although apparently compound-related, the response
did not increase in a dose-response relationship.
Owing to the physical status of all dams in the
study (evidence of ascites and pitted kidneys) a
clear relationship between compound administration
and effect cannot be established and the study is
considered supplementary.   Therefore, the biological
significance of the responses observed roust be clarified.

A rabbit teratology study is required.

There are not sufficient data available to assess
the teratogenicity of fenamiphos in rats.  A
rat teratology study is required.

Rep r o duct ion.  An adequate study in rats assessing
the reproductive effects of fenamiphos over at least
two generations is available.  Thirty-three-day
old FB30 rats (10 males/20 females/group) were fed
dietary levels of 0, 3, 10 and 30  ppm through three
generations.  Dietary levels of 3  and 10 ppm had no
effect on behavior or body weight  gain of the males
or females.  Male rats of the F2b  generation fed
30 ppm gained less weight than the control males of
the same generation.  There was no difference between
the test and control animals with  respect to fertility,

-------
                          15
litter size, average weight of pups at birth, and
lactation performance of the dams.  The reproduction
NOEL is 30 ppra.

No further reproduction studies are required at
this time.

Muta_ge_n ic ity Studies_.  Fenamiphos was negative when
tested in the CHO/HGPRT mutation assay and in the
dominant lethal mutation assay.  Data are'-required
however, to assess direct DNA damage.

4.  Metabolisjn. Studies.  Data are not available
to determine the degree of tissue accumulation and
elimination in rats resulting from multiple doses
of fenamiphos.  The major metabolites of fenamiphos
have been identified from single dose studies as
the sulfoxide and sulfone.  However, the metabolic
pathway for the desisopropyl metabolites needs to
be defined.

A guideline multiple dose rat metabolism study is
required.

The sulfoxide, sulfone, and des-isopropyl analogs
of fenamiphos are as highly toxic as the technical
material; the phenolic metabolites are low in
acute toxicity.

5.  Spec i a 1 S_tu4i e.s_.

Antidotal.  Sufficient data are available to
determine the efficacy of atropine and 2-PAM in
treating fenamiphos poisoning in male and female
rats.

Atropine increased the LD5Q of fenamiphos by five
times and 2-PAM increased the LD5Q of fenamiphos by
six times the value for untreated animals.  The
combination of atropine and 2-PAM were no more
protective than either compound alone.

6.  Ri.sk Assessment

    0  Fenamiphos is acutely toxic to laboratory animals,
       Toxicity Category I,  by the oral,  dermal, and
       inhalation routes of  exposure.

    0  Fenamiphos is not a delayed neurotoxicant.

    0  Fenamiphos is not oncogenic in rats or mice.

    0  No dose-related increase in neoplastic and non-neoplastic
       histopathological lesions was observed from feeding
       dietary levels of 2,  10, and 50 ppm to male and female
       rats for 2 years.  No gross or histopathological
       changes were attributed to feeding dietary levels of
       .5 to 10 ppm to Beagle dogs for 2  years.   The dietary
       cholinesterase NOEL for fenamiphos is 1.0 ppm for
       both rats and dogs.

    0  There is not sufficient data to fully assess the
       teratogenic potential for fenamiphos.  Further
       studies in the rat and rabbit are  required.

    0  No adverse reproductive effects were observed in a
       3-generation rat reproductive study.

    0  Fenamiphos was not mutagenic in the test  systems
       assayed.

C.  OTHER SCIENCE FINDINGS

Environmental Fate.  Available data are insufficient to fully
assess the environmental fate of fenamiphos.   Except for
data pertaining to hydrolysis and photodegradation in water,
the information discussed below is considered supplementary
and is provided from studies that did not fulfill the data
requirements for registration; the later studies must be
repeated.

     1.  Hydrolysis.  A radiolabeled hydrolysis study demon-
     strates that fenamiphos degrades with half-lives of 7 to
     14 days at pH 3, >30 days at pH 9, and appears to be
     stable at pH 7 when incubated in the dark at 30°C.
     This data suggests that fenamiphos is relatively stable
     in neutral and alkaline solutions.  The primary degra-
     dation product in the pH 3 solution was deaminated
     fenamiphos (74-78%).  Degradates identified in the
     methylene chloride extracts from pH 3, 7, and 9 solutions
     included fenaroiphos sulfoxide, fenamiphos sulfone,
     fenamiphos phenol, fenamiphos sulfoxide phenol, and
     fenamiphos sulfone phenol.  No further hydrolysis
     studies are required.

     2.  Photodegradation in Water*  A radiolabeled degradation
     study demonstrates that fenamiphos degrades with a half-
     life of 2 to 4 hours in pH 7 buffered water irradiated
     with artificial light.  After 24 hours of irradiation,
     fenamiphos accounted for approximately 4% of the
     applied radioactivity, fenamiphos sulfonic acid phenol
     for approximately 19%, fenamiphos sulfoxide for
     approximately 17%r fenamiphos sulfonic acid for 6%,
     and fenamiphos sulfoxide phenol for 1%.   No further
     water photodegradation studies are required.

     3.  Photodegradation in Soil.  Ring-labeled fenamiphos
     degraded with a half-life of <1 hour on sandy loam soil
     irradiated with artificial light.  After 48 hours of
     irradiation, fenamiphos and the degradates fenamiphos
     sulfoxide and fenamiphos sulfone accounted for approxi-
     mately 12, 55, and 6% of the extractable radioactivity,
     respectively.  This study does not fulfill data
     requirements because the material balance was incomplete;
     not all the material was accounted for.   Data on the
     photodegradation of fenamiphos in soil are required.

     4.  Aerobic Soil Metabolism.  Available data are
     inadequate to assess the metabolism of fenamiphos
     in aerobic soil.  The study'does not fulfill data
     requirements because the soil was not characterized
     and the material balance was incomplete.  Data on the
     metabolism of fenamiphos in aerobic soil are required.

-------
                               18
 5.  Anaerobic Soil Me.tabolism.  Data on the metabolism of
     fenamiphos in anaerobic soil are required.

 6.  Leaching and Ads.o.rp_ti.o_n/DTe_s_orp_t_ic>n Studies.  Available
     data  (8 studies) are inadequate to assess  leaching
     and adsorption/desorption.  Data on leaching and
     adsorption/desorption of fenamiphos are required.

 7.  Laboratory VQl.ati.l.ity, Studies.  No data were reviewed.
     Laboratory volatility Studies are required.

 8.  Field Volatility Studies.  The data requirement is deferred
     pending receipt of acceptable laboratory volatility studies.

 9.  Terre.s trial Field, Dissipation Studies^  Available data
     Til studies) are inadequate to assess terrestrial field
     dissipation.  Data on the terrestrial field dissipation
     of fenamiphos are required.

10.  Aquatic Field Dissipation.  No data were reviewed;
     however, no data are required because fenamiphos has
     no registered aquatic food crop, aquatic nonfood,
     or aquatic impact uses.

11.  F.orestjry Dis_sij>ation Studies,  jqo data were reviewed;
     however, no data are required because fenamiphos has
     no forestry uses.

12-  Long^-1erm F ieJL d Djssipation S_tudie_s_.  No data were
     reviewed.  The data requirement is deferred pending
     the receipt of acceptable field dissipation data.

13.  Confined AccumulatiQn[Studi.es .on Rotational Crops.
     Radio-labeled fenamiphos residues accumulated in mustard,
     sugar beets, and a grain crop planted 31 and 115 days
     after formulated radio-labeled fenamiphos was applied
     at 6 Ib ai/A to a loamy sand soil.  Parent fenamiphos
     was not detected in any crop; two degradates, fenamiphos
     sulfoxide and fenamiphos sulfone were detected at
     0.01-0.18 and 0.01-0.23 ppm, respectively in all crops.
     Radio-labeled fenamiphos residues dissipated with a
     half-life of 308 to 328 days in the loamy sand soil.
     This study does not fulfill data requirements because
     the test substance was not analytical grade, residues
     in the soil were not characterized, residues in the
     crops were not adequately characterzied and meteoro-
     logical data were inadequate.  Therefore, data on the
     accumulation of fenamiphos .in confined rotational crops
     are required.

 14.  Field Accumulation Studies on Rotational Crops.
      Fenaraiphos residues were not detected in rotational
      radish, snap beans, or sorghum planted approximately
      364 days after fenaroiphos was applied at 1.5 and 3.0 Ib
      ai/A to silty clay loam soil.  Fenamiphos residues were
      £0.06, £0.03, 0.01, and <0.01 in mature rotational crops
      (turnips, blackeyed peas, and corn)  planted approximately
      30, 90, 120, and 364 days, respectively, after fenamiphos
      was applied at 1.5 to 6.0 Ib ai/A to sandy soil.  This
      study does not fulfill data requirements because the
      test substance was not characterized, the analytical
      method was nonspecific, residues in soil and crops were
      not characterized, and residues in the soil were not
      analyzed at the time of treatment.  Data on the accumu-
      lation of fenamiphos in field rotational crops are
      required.

 15.  Accumulation Studies on Irrigated Crops.  Data on the
      accumulation of fenamiphos in irrigated crops is
      required.

 16.  Accumulation Studies in Fish.  The one study reviewed is
      inadequate.  Data on the accumulation on fenamiphos in
      fish are required.

, 17.  Field Accumulation Studies on Aquatic Nontarget Organisms.
      No data were reviewed; however, no data are required
      because fenamiphos has no forestry,  aquatic noncrop,
      or aquatic impact use.

 18.  Groundwater.  The potential for fenamiphos to reach
      ground water cannot be determined at this time.  Of the
      seven studies required under the Groundwater Data Call-in,
      only two, hydrolysis and photodegradation in water, met
      guideline requirements.  The Agency will evaluate the
      potential of fenamiphos to contaminate ground water after
      it has received and evaluated the following required
      data:  photodegradation in air, aerobic and anaerobic
      metabolism, mobility, and field dissipation.  The
      sulfoxide and sulfone metabolites of fenamiphos are
      included in the National Survey for Pesticides in Drinking
      Water, in lieu of parent fenamiphos, as the parent
      readily degrades.

Ecolggical. Effects.  Available data are insufficient to
completely evaluate the ecological effects of fenamiphos.
Data as set forth in Appendix I, Table A are either required
or reserved pending further evaluation.  The following
conclusions can be made based on available data.

!•  Toxicity to Birds and Mammals.

    Technica 1 JFenamipho s.  Fenamiphos can be characterized
    as very highly toxic to the bobwhite quail (LDso
    1.6 mg/kg, LCso 38 ppm) and highly toxic to the mallard
    duck (LCso 316 ppm).  Results of a bobwhite quail
    reproductive study demonstrated that dietary exposure  of
    8 ppm reduced chick survival by 31 percent with a NOEL
    of 2 ppm.  Results of a mallard duck reproductive study
    demonstrated that dietary exposure of 16 ppm reduced
    feed consumption and egg production with a NOEL of 8
    ppm.  These data indicate that fenamiphos causes some
    reproductive impairment in both upland game birds and
    waterfowl at exposure levels of 2 and 8 ppra,
    respectively.

    Granular 15 G.  Applications of Nemacur* 15G at a rate
    of 134 Ibs. ai/acre to turf, without irrigation,
    resulted in 70 and 15 percent mortality to English
    sparrows and bobwhite quail, respectively, when these
    birds were penned on the treated area.  Even with
    1/2 inch irrigation immediately following application,
    50 percent of the English sparrows penned on treated
    plots died.  Little or no hazard to penned birds was
    reported when Nemacur* 15G was both soil incorporated
    and unincorporated after band application (27 oz.
    formulation/1,000 feet of row) and incorporated after
    broadcast treatment (40 Ib. formulation/acre).
    Results of these studies suggest that soil incorporation
    of granules reduces hazards to avian species.

    Emulsifiable Concentrate (35%).  Applications of
    Nemacur* 3 (35% SC) at rates of 6, 10, and 20 Ibs.  ai/
    acre and soil incorporated 2 to 3 inches resulted in
    approximately 10% mortality to bobwhite quail.  In another
    small pen study with pheasants and rice birds, application
    of Nemacur* 3 at 5 Ib.  ai/acre on pineapples, resulted in
    approximately 25% mortality to the rice birds.  Both
    significant avian and mammalian mortality was reported
    when 26 acres of orchard were sprayed with Nemacur* 3
    at a rate of 23.5 Ibs.  ai/acre without soil incorporation.

-------
                             21


    Results of the above studies suggest that soil  incorpor-
    ation and/or irrigation will somewhat reduce hazards to
    non-target avian and mammalian species.

    Because of study design deficiencies, none of the field
    studies discussed above fulfills the data requirements.
    A terrestrial field study is being required to  determine
    if the hazard indicated by these laboratory and field
    studies are below the levels of concern  for mammalian
    and avian species under actual use conditions
    (Appendix I, Table A).


2«  Toxicity to Fish, Aquatic Invertebrates,  and Estuarine/
    Marine Organisms.

    Technical Fenamiphos^.  The lowest 96-hour LCso  for bluegill
    sunfish was determined to be 9.6 ppb, while the lowest
    96-hour LCso for rainbow trout was 72.1  ppb. These data
    suggest that fenamiphos is very highly toxic to both warm
    and cold water fish.  The lowest 96-hour LCsos  for the
    bluegill sunfish for the two major degradates of the parent
    material were determined to be 2,000 and 1.173  ppb for the
    sulfoxide and sulfone group.  The major  metabolites of
    fenamiphos are considered to be moderately toxic to warm
    water fish.

    Granular 15 G.  One study, involving two fish species, was
    conducted using the 15G formulation.  The 96-hour LCso
    values were determined to be 151 and 563 ppb for the blue-
    gill sunfish and rainbow trout, respectively.  Based on
    the LCso values listed above, the 15G formulation appears
    to be less toxic than the technical but  still highly toxic
    to both warm and cold water fish.

    The following additional studies are being required:
    an acute LCso ^or fish using the 21 and  35% spray concen-
    trate products; an acute LCso f°r freshwater invertebrates
    using the technical and formulated products; an acute LCso
    for estuarine and marine organisms; fish early  life stage;
    fish life cycle; aquatic invertebrate life cycle; acquatic
    organism accumulation;  and simulated and actual field
    testing of aquatic organisms (Appendix I, Table A).

3.  Ecologicra.! Effects Hazard Assessment.   Because of  the
    ecotoxicological and environmental Yate data gaps,  there
    are insufficient data to fully assess  the direct and
    indirect hazards of fenamiphos to nontarget fish and wildlife
    species.  However, there are sufficient data to make certain
    preliminary statements about the acute and chronic hazards
    of fenamiphos to these species.

    a.  Terrestrial Aazard Ass_e_s_s_ment .
        (1).   Granular Formulation.   Exposed fenamiphos  granules
        pose  a hazard because of their high tpxicity to  both
        mammalian and avian species.   Field studies  conducted
        with  fenamiphos have documented that non-target  birds
        and mammals can ingest lethal doses of granular
        pesticides during the course  of their normal feeding
        activities.  Agency-sponsored field studies  also indicate
        that  bird species which typically forage the soil for
        food  or grit may also be exposed to soil incorporated
        granules. (Also, the use of  sprinkler irrigation, to
        incorporate granules, may result in high levels  of
        fenamiphos being concentrated in small puddles or wet
        spots which may also pose hazards to nontargets  when
        they  are drinking).

        The hazards to nontarget mammalian and avian species
        posed by granular fenamiphos  (15G) are based on  the
        maximum application rates of  66 to 133 pounds formulated
        product (9.9 to 20.0 Ib ai/A) per acre to tobacco,
        fruit trees, and ornamentals  (soil and turf) and the
        LD5Q  for the most sensitive  organisms tested.  Label
        directions call for the 15G  formulation to be soil
        incorporated 2 to 4 inches deep or irrigated into the
        soil  immediately following application.

        Although soil incorporation may reduce the potential
        for nontarget exposure, it does not eliminate it.
        Studies have shown that even  with the roost modern
        equipment, some granules still remain on the surface.
        Erbach and Tollerfson (1981)  using commercially
        available equipment found that 5 percent of  the

-------
                         23
granules applied remained on the soil surface.
In another study/ counts conducted immediately after
incorporation revealed that both row areas (x =
70 granules/sg ft) and end row turn areas (x =
344 granules/sg ft) contained large numbers of
exposed granules.

One way of assessing the potential for this hazard,
under field conditions, is to compare the amount of
toxicant available on a square foot basis with the
acute oral LDso value(s) for the species likely to
be exposed.  The closer the value is to the LDso the
greater the degree of hazard.  Support for this
approach can be found in the literature.  Dewitt (1966)
after conducting a quail field study concluded/ "losses
of birds may be expected if the quantity of toxicant
per square foot equals or exceeds the quantity causing
deaths of quail in short term feeding tests." Additional
support is provided by Tucker (1972) who has reported
that field kills have occurred in many instances when
the amount of toxicant applied per acre exceeded 50,000
LD5QS (equal to approximately 1 LDso per square foot).

Using the recommended application rate of 133 Ib
product/acre (95 percent soil incorporation assumed)
and the average weight of one granule/ 0.093 mg, the
number of granules per square foot has been calculated
to be 745 granules (10.43 rog ai) per square foot
(Table 2).

(a).  Avian Hazards,.  The primary routes of exposure
      tx> avian species are expected to be from the
      ingestion of granules and grit and drinking
      contaminated water.  Based upon the acute oral
      LD5Q value for bobwhite quail (16.0 rag/kg of
      15G) and the average weight of the 15G granule
      (.093 mg)/ the number of granules equivalent to
      the LD5Q values for six avian species has been
      determined (Table 3).

      When these values are compared to the average
      number of granules per sq. ft. resulting from
      the maximum application rate/ 745 granules/sq.
      ft. (Table 3), it appears that there is little
      margin for safety especially for small birds
      that forage for food or grit on the soil surface.
      In the case of the bobwhite quail which has the
      largest LDso value of the six species in the
      table (equivalent to 34.4 granules)/ the average

               26
number of granules per square foot equals 21.7
LDso values, suggesting a very high degree of
hazard.  Again, these values suggest that the
smaller birds, for example the house sparrow
(with 217 LD5Q equivalents per square foot),
are at the greatest degree of risk.  Although
these calculations clearly indicate that this
level of exposure may put birds at risk, further
exposure analysis cannot be made without
additional data; therefore simulated and actual
field testing for birds is being required via
this Registration Standard so that an accurate
determination of risk can be made.

The Agency has also compared the potential
toxicity of fenamiphos to restricted use criteria.
The avian acute oral LD$Q of 16.0 mg(15G)/kg for
the bobwhite quail exceeds the Agency's proposed
restricted use criteria for hazard to avian species
of 50 mg/kg for granular products (U.S.E.P.A.,
"Hazard Evaluation Division, Standard Evaluation
Procedure", EPA-540/9-85-001, p. 57. June 1986).

In addition, fenamiphos exceeds the restricted
use criteria for avian species set forth in
40 CFR 162.11(c)(2)(iii)(B); exposure exceeds
1/5 the subacute dietary LCso for the bobwhite
quail.  The subacute dietary LCso of 179 ppm
was calculated from the acute oral LDso of
16.0 mg/kg for the 15G formulated product and
food consumption and body weight data.  The
formula for calculating the LCso is as follows:

Calculated LCso * LD5o/(food consumption/body weight)

The 15G formulation contains 150,000 ppm
fenamiphos; this dietary exposure far exceeds
1/5 the LC50 (179/5).

Finally, fenamiphos exceeds the restricted use
criteria for non-target organisms outlined in
40 CFR 162.11(c)(2)(iii)(D).  As discussed above
under "Toxicity to Birds", the 15G formulation
has resulted in mortality to English sparrows
and bobwhite quail, thus exceeding the criteria
of "...minor or no discernible adverse effects...".

-------
                    27
(b).   Mammalian  Hazards.   Possible  routes  of  exposure
      to mammals from granulated formulations are
      from ingestion of  granules, feeding  on
      contaminated vegetation/ invertebrates  or
      drinking contaminated water.   Based  on  body
      weight and acute oral toxicity data,  the number
      of granules equivalent  to an  LDso  for four
      species of mammals (Rat, Eastern Cottontail,
      Grey Squirrel, and Delmarva Fox),  known to
      frequent agricultural areas,  have  been
      calculated (Table  4).

      The average number of granules per square foot,
      745, exceeds the LD5Q for all but  one of the
      four species,  the  Eastern cottontail.   In the
      case of the rat, the number of granules per
      square foot exceeds the LD5Q  by 2.6  times.
      These data suggest that in terms of  the available
      LDso equivalents/sq. ft., small mammals are at a
      greater risk than  large mammals and  that very
      small rodents such as Microtus, Perpmyscus, and
      Reit h rp_d oji t omy s are very likely to be exposed
      to lethal  levels of fenamiphos from  the 15G
      formulation.

      Laboratory studies have shown that the  sulfoxide
      is as toxic as the parent material.   Environmental
      fate data  show that fenamiphos and its  metabolites
      are picked up systeraically by plants and that
      sulfoxide  residue  may be present in  certain
      soil for up to 2 years  after  application.
      These data suggest that small mammals feeding
      on contaminated vegetation are also  likely to be
      exposed to fenamiphos and/or  its metabolites.
      This is another issue that should  be explored
      under simulated and actual field conditions.

      The above  discussion clearly  indicates  that
      mammals can be potentially exposed to fenamiphos
      either from ingestion of granules  or from
      feeding on contaminated vegetation at levels
      that may put them  at risk. Further  exposure
      analyses cannot be made without additional
      data; therefore simulated and actual field
      testing for •mammals are being required  via this
      Registration Standard so that an accurate
      determination of risk can be  made.

     Fenamiphos also exceeds the restricted use
     classification criterion for mammals (1/5 the
     acute oral 1*050) by 5 to 15 times for all four
     species in Table 4, indicating that unrestricted
     use of fenamiphos would constitute unreasonable
     adverse effects to mammals [40 CFR 162.11(c)(2)
     (iiiHA)].
(2).  Emulsifiable Concentrate Formulation.  As
previously discussed,results of field studies suggest
that the emulsifiable concentrate spray formulations,
even when soil incorporated, cause mortality to both
avian and mammalian species.  The evidence also
suggests, however, that soil incorporation does
reduce hazard to some extent.

The extent to which avian species may be exposed
and the degree of hazard from such exposure is shown
in Tables 5 and 6.  This hazard assessment for the
SEC formulation was based on exposure from the maximum
application rate of 20 Ib ai/A for fruit trees, and
ornamentals (sod and turf), and dietary subacute
toxicity data for the most sensitive species tested
(bobwhite quail LCjjQ 38 Ppm).  Because label directions
call for both broadcast and band applications to be
soil incorporated immediately following application,
the application rate of 20 Ib ai/A has been adjusted
to 1 Ib ai/A to account for 95% soil incorporation.
Table 5 presents the food factor calculations and
correlation of total adjusted residues with calculated
LCso values for various species.  Table 6 shows
estimated dietary concentrations and the total
estimated residues for eight species of nontarget
birds.

Comparisons between expected dietary concentrations
and LC5Q values for eight species of nontarget birds
suggest the following:

      1.  Small insectivorous birds such as the
      Carolina wren are likely to be exposed to
      the highest residues of fenamiphos and as such
      are the most susceptible to hazard.

-------
                                           30
                         2.  Seed-eating birds  such as the Mourning dove
                         are likely to be exposed  to the lowest residues
                         of fenamiphos.

                         3.  Residues of fenamiphos exceed NOELs for
                         tested avian species  (2 and 8 ppm for upland
                         gamebirds and waterfowl,  respectively) and
                         suggest  that reproductive impairment may occur
                         under field conditions.

                         4.  Mortality and or/other adverse effects
                         associated with cholinesterase inhibition
                         may occur to certain species regardless of
                         size.

                         5.  Total fenamiphos residues exceed the
                         calculated subacute dietary LC$Q for four
                         species.

                         6.  As the residue calculations in Table 6
                         assume 95% soil incorporation  (which reduces
                         the application rate of 20 lb€ ai/ acre to
                         estimated residues of  1 Ib ai/acre), it is
                         apparent that failure  to  adequately soil
                         incorporate broadcast  or  band applications
          /              will greatly increase  exposure and potential
                         for adverse effects.

                         7.  Total fenamiphos residues exceed 1/5
                         the calculated subacute dietary LC$Q for all
                         eight species (restricted use classification
                         criterion, 40 CFR 162.11  (c)(2)(ill)(B)).

                  In addition, the emulsifiable concentrate formulation
                  of fenamiphos exceeds the restricted tree classification
I                  criteria as set forth in 40  CFR 162.life)(2)(iii)(D).
                  Use of the 35% EC formulation resulted in significant
                  avian  and mammalian mortality,  thus exceeding the
                  criteria of "...minor or no  discernible adverse
                  effects..."-

I/ All of the calculations for calculated LCso (ppm),  except for
   38 ppm which is the reference LC$Q, are based upon the
   assumption that each species has the same sensitivity to

   weight and food consumption values are from Kenaga (1973),
   Nice (1938), and USD1, USFWS, Circular 199, 1964.

   These are the theoretical dietary levels which should cause
   50% mortality (LCso) using the assumption stated in (1) above
   (see Kenaga (1972 and 1973)).  The procedure used is:
    Food Consumption (%) x  Toxicant   (ppm)

   Kenaga (1973)r  In this article the food consumption values
   for a 19.0 gm three sparrow (Spizella arborea) are given as
   7.11 and 5.95 gm, the mean equaling 6.53 gm.  This value is

Aquatic Hazard As.sessment.  Because fenamiphos has
been characterized as very highly toxic to both cold
and warm water fish species, the Agency is particularly
concerned about the direct and indirect hazard that
this material may pose to aquatic environments.

The terrestrial food crop uses where aquatic
contamination is of primary concern are citrus,
nonbearing fruit trees and tobacco where drift,
runoff, and soil erosion of fenamiphos to lakes,
streams, ponds, and other bodies of water and wetlands
may occur.  Obviously, the greatest potential for
hazard to fish would occur if, during treatment,
fenamiphos was directly applied to aquatic environments.
There are no registered uses for direct application
to water.  However, such a circumstance could easily
occur if fenamiphos were aerially applied as a broadcast
soil treatment to fields where citrus, orchards, and
tobacco are to be planted; and where interconnected
waterways such as ditches, canals, creeks, streams,
and ponds are used for irrigational purposes.  Ground
application would, for the most part, preclude any
direct application to wetland areas.  However,
contamination could still occur from runoff.

Table 7 shows the estimated environmental concen-
trations of fenamiphos that could occur from direct
application to water at the maximum accepted rate
for three sites: citrus, fruit trees,"and tobacco.
Comparing the 96-hour bluegill sunfish LCso of 9.6
ppb, the estimated exposures suggest that direct
application of fenamiphos to lentic (sluggish) bodies
of water (worst case situation) will result in
residues in six inches of water that exceed l/10th
the LC^Q by 1,250 times (1200ppb/0.96 ppb) and will
most likely cause significant adverse effects.
One-tenth the LCso for aquatic organisms is the
criteria for restricted use classification as specified
in 40 CFR 162.11(c)(2)(iii)(C).

Table 8 shows the estimated environmental concentrations
of fenamiphos in runoff for both lentic (sluggish) and
lotic (actively moving) environments.  EECs for
fenamiphos from runoff have been determined for both
lentic and lotic environments using the EXAMS II
(Exposure Analysis Modeling System).  To determine
these EECs, the amount of runoff from a 10 hectare
tobacco field (i.e., unit of runoff/acre from SWRRB
x 10) was foaded into a Georgia pond (lentic)/ stream
(lotic) scenario to simulate the fate of fenamiphos
in a Georgia aquatic system.  The Georgia pond-stream

-------
                        36
scenario consists of a one hectare farm pond, 2
meters-deep, that is surrounded by a 10 hectare
drainage basin and drains into two streams.  One is
short (100 meters-long, 3 meters-wide and .05 meter
-deep), and one is long 300 meters-long, 3 meters-
wide, and .05 meter-deepr).  EECs were based on an
application rate of 20 Ibs ai/A, soil incorporated
(2-4") and/or watered-in (95% incorporation assumed).

Comparison of fish toxicity data and the EEC's in
Table 8 suggest that nontarget fish indigenous to
small ponds and streams will be exposed to fenamiphos
residues in runoff (worse case situation) that are
above the LCso value (9.6 ppb) and restricted use
classification criteria (1/10 LC50 « .96 ppb) and
will most likely cause significant adverse effects.

In order to accurately determine the potential
exposure and toxicity of fenamiphos to aquatic
environments the Agency is requiring the aquatic
toxicity tests listed in Appendix I/ Table A of
this standard which include simulated and actual
field testing of aquatic organisms.

Species of the Fish and Wildlife Service concerning
the potential adverse effects on endangered and
threatened species for the cotton and soybean uses
of fenamiphos.  OES issued biological opinions which
found that these uses jeopardize the survival of the
following species.

Reentry Con^i operations.  Toxicity and exposure criteria
are set forth in 40 CFR.158.  If a chemical meets the
specified criteria, reentry data are required.

Fenamiphos meets the toxicity criteria in that the technical
grade of the active ingredient has an acute dermal toxicity
of less than 200 mg/kg body weight, an acute inhalation
toxicity of less than 200 mg/ra3 for a one-hour exposure,
and an acute oral toxicity of less than 50 mg/kg body weight.

Fenamiphos also meets the exposure criteria in that it is
registered for use on crops where current agricultural
practices include human tasks which involve substantial
exposure to residues of the pesticide.  An interim 48-hour
reentry interval is being imposed until adequate data
have been submitted and evaluated.
Product Chejnistry,.  The Agency has evaluated data which
Tdentify the ingredients, materials, and manufacturing
process and discuss the physical and chemical properties of
fenamiphos.  Additional product chemistry data as identified
in Appendix I, Tables A and B, are being required.

-------
                              41
 D.  TOLERANCE REASSESSMENT

       Tolerances have been established for residues of
 fenamiphos in a variety of raw agricultural commodities, in
 meat, fat and meat byproducts (40 CFR 180.349  [a] and  [b]),
 and in processed food (21 CFR 193.463) and feed  (21 CFR
 561.232).

      EPA has evaluated the residue and toxicology data
 supporting tolerances, and has made the following.regulatory
 determinations:

      °Whether the current tolerances and food additive regu-
 lations are sufficient to cover the actual residues resulting
 from use (including uses registered under FIFRA  sec. 24(c)
 and intrastate uses).

      "Whether group tolerances can be established in accor-
 dance with 40 CFR 180.34(f).

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

      •Whether the tolerances are expressed accurately and in
/ current terminology.

      The regulatory determinations resulting from EPA's
 review are set out in Section IV.A. of this document,
 Regulatory Positions and Rationales.

      1.  Residue Data.

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

      a-  Data on tjhte nature of the residues in both plants
      and aKimaIs, ^including identification of major roetabolites
      andi ,degradates of f e_r>amip_hos).  The metabolites of
      fenamiphos are fenamiphos sulfoxide (FSO),  fenamiphos
      sulfone  (FSC>2)r des-isopropyl fenamiphos  (DIP), des-
      isopropyl fenamiphos sulfoxide (DIFSO), fenamiphos
      sulfoxide phenol (FSOP), fenamiphos sulfone phenol
      (FSC>2P)» and fenaraiphos phenol (FP).  Tolerances for
      residues of fenamiphos in food items derived from plants
      are currently expressed in terms of the combined residues
      of fenamiphos-and its cholinesterase-inhibiting metabolites,
      fenamiphos sulfoxide and fenamiphos sulfone.  Tolerances
      for residues of fenamiphos in food items derived from
      animals are expressed in terms of the combined residues
      of fenamiphos and its sulfoxide and sulfone as well as
      des-isopropyl fenamiphos, des-isopropyl fenamiphos
      sulfoxide and des-isopropyl fenamiphos sulfone.

-------
                            42
b.  Radiolabeled studies on .the uptake, translocation
and metabolAsm Qf_ f_enamiphos in jplants show that
metabolic pathways involve oxidation of fenamiphos to
fenamiphos sulfoxide and/or fenamiphos sulfone and
subsequent hydrolysis to fenamiphos sulfoxide phenol
and fenamiphos sulfone phenol and formation of
glucoside and other conjugates.  Although the phenols
are present as significant portions of the total
residue in plants, they are not currently included in
the tolerance expression because the Agency has no
concern regarding their toxicological significance at
this time.

c.  Radiolabeled studies on the metabolism _amj. translo-

shdw "that the meta&olism off fenamiphos Tn poultry
(including eggs) and ruminants  (including milk) is not
adequately understood.  In addition to the known plant
metabolites, des-isopropyl fenamiphos and des-isopropyl
fenamiphos sulfoxide have been  found in ruminant tissues
and milk after dosing with fenamiphos sulfoxide.
     There are deficiencies in  available hen, ruminant,
and swine metabolism studies.   Therefore, metabolism
studies utilizing ruminants and poultry in which ring-
labeled [l^c] fenamiphos is administered are being
required.   In addition tissue samples from these studies
must be analyzed using current  enforcement methods.
Should the metabolism of fenamiphos in ruminants or
poultry be found to differ significantly from that in
rats, additional swine metabolism studies may be required.

d.  Analytical methodology. ,f or jdeterminlng the levels o_f

of fVnamipnos "sulfoxicfe" ana fenamiphos sulYone in or on
plant and animal commodities and of des-isopropyl
fenamiphos, des-isopropyl fenamiphos sulfoxide, and
des-isopropyl fenamiphos sulfone in or on animal
commodities must be subjected to analysis by multiresidue
protocols available from the National Technical
Information Service (NTIS).  Additional methods,
validation data and residue data may be required if
metabolism studies indicate additional metabolites of
toxicological concern in animals.

-------
                           43
e*  g^tQirage stability data.  Fenamiphos, fenamiphos
sulfoxideT and fVnaraiphos sulfone are stable in frozen
plant commodities stored up to 1,086 days.  Additional
storage stability data for residues in muscle, fat,
liver, kidney, milk, and eggs are necessary because
the available data indicate poor stability in animal
tissues and products after 64-75 days of frozen storage.
Data on storage intervals and conditions of storage of
previously submitted samples must be submitted and
accompanied by fortification recovery data for all
animal commodity samples and any plant samples stored
longer than 3 years.
     It should be noted that the nature of the residue
in animals has not been adequately described.  If
the requested metabolism data indicate the presence
of additional residues of toxicological concern in
animal commodities, data depicting the stability of
such residues in storage will be required.
f .  Data on^ ^the magnitude _am3 levels pf res. idues of
fenamiphos in _i_ndiyi_dual raw agricultural commodities,,
animal ^products, .and. I>rQcessed food and feed items.
Sufficient data are aval Table to ascertain the
adequacy of the established tolerances for residues
of fenamiphos in or on the following raw agricultural
and processed commodities: brussels sprouts, cabbage,
soybeans, grapefruit, lemons, limes, oranges, tangerines,
dried citrus pulp, citrus oil, citrus molasses, apples,
dried apple pomace, cherries, peaches, grapes, raisins,
raisin waste, raspberries, asparagus, cottonseed, okra,
peanuts, and pineapples.
     Insufficient data are available to ascertain the
adequacy of the established feed additive tolerances
for residues in dried grape pomace and pineapple
bran.  Also, processing studies are required for the
following commodities:  soybeans, grapes (juice and
dried pomace only), cocoa beans, cottonseed, peanuts,
meat, and milk,
     Sufficient documentation is not available to
ascertain the adequacy of the established tolerances
for fenamiphos residues in or on garlic, bananas, and
cocoa beans imported into the U.S.  Also, additional
residue data are needed for cocoa beans.

-------
  2-   Toxicology Data.

      The  toxicology  data  considered  in  support of the tolerances
  include:

          2-year dog  feeding  study; NOEL =  .025 mg/kg of
          animal body weight/day

      The Acceptable Daily Intake  (ADI) and Maximum Permissible
  Intake  (MPI)  are  two ways of expressing the amount of a
  substance  that the  Agency believes, on the basis of the
  results  of data from animal studies and the application of
  "safety" or  "uncertainty" factors, may safely be ingested by
  humans without risk of non-oncogenic adverse health effects.
  The  ADI  is expressed in  terms of milligrams (mg) of the
  substance per kilogram (kg) of  body weight per day (mg/kg/day).
  The  MPI, a related  figure,  is obtained by assuming a human
  body weight of 60 kg, and is expressed in terms of mg of
  substance per day  (mg/day).  The Agency has calculated a
  Provisional ADI (PADI) of 0.00025 mg/kg/day for fenamiphos
  due  to the lack of  an adequate  teratology study.  The MPI
  for  fenamiphos is 0.015  mg/day.

      The PADI for fenamiphos currently is based on the results
/ from a 2-year dog feeding study, from which the Agency
  concluded  that the  no-observed-effect-level (NOEL) was seen
  at 1 ppm of the substance in the animals' diet, or 0.025
  mg/kg of ajiimal body weight/day.  Cholinesterase inhibition
  was  seen at all other dose  levels, 2,  5, and 10 ppm.  The
  PADI was derived  by use  of  a safety factor of 100 to account
  for  the  lack  of an  adequate teratology study.  The NOEL
  from the dog  study, 0.025 mg/kg/day divided by this 100-fold
  factor, yields a  human PADI of  0.00025 mg/kg/day.  The MPI
  for  a 60-kg human is 0.015  mg/day.

      The theoretical maximum residue contribution (TMRC) is
  the  theoretical maximum  amount  of residue of a pesticide
  that might be present in the human diet, based on assumptions
  the  Agency makes  about the  average human daily intake of
  foods containing  residues at the level of the established
  tolerances.   The TMRC for the U.S. population average based
  on published  tolerances  only is 0.0020 mg/kg/day which occupies
  812% of  the PADI.   Utilization  of anticipated residues and
  percent of crop treated  lowers  this estimate to 0.00011 mg/kg/
  day  which corresponds to 42% of the PADI.

-------
                                45
     Dietary exposures for 22 subgroups of the U.S. population
have also been estimated.  The two highest highest calculated
exposures (published tolerances only) were non-nursing infants
with a THRC of 0.0067 rag/kg/day which occupies 2684% of the
PADI, and children 1 to 6 years of age with a TMRC of 0.0056
rag/kg/day which occupies 2230% of the PADI.  Utilization of
anticipated residues and percent of crop treated lowers
these estimates to 0.0003 mg/kg/day, which occupies 112% of
the PADI, and 0.0002 mg/kg/day, which occupies 96% of the
PADI, respectively.  Since meat and milk contribute
significantly to the TMRC, it is possible that the required
processing studies that will demonstrate the effect of cooking
meat and the pasteurization of milk or the production of
infant formula on residue levels of fenamiphos and its
metabolites, may lower the estimated dietary exposure for
these two subgroups in particular in addition to the overall
U.S. population.

     Since the PADI is a provisional value, it is possible that
resolution of the teratology data gap may allow for a lower
uncertainty factor which will result in a higher ADI and
consequently a lower percentage of the ADI occupied by the
TMRC.

                               46
3.  Tolerances issued.

      Tolerances have been established for residues of
fenamiphos in a variety of raw agricultural commodities
(40 CFR 180.349  [a]), in meat, fat and meat byproducts
(40 CFR 180.349  [b]), and in processed food (21 CFR 193.463)
and feed  (21 CFR 561.232).

     There are no Mexican or Canadian tolerances for fenamiphos.
To permit compatibility with Codex Maximum Residue Limits
(MRLs), the Agency is; (1) reducing the tolerances for residues
in or on brussels sprouts and cabbage from 0.1 to 0.05 ppm;
(2) establishing a crop group tolerance of 0.5 ppm for residues
in or on citrus fruit (with a concomitant revocation of the
0.6 ppm tolerances for residues in or on oranges* grapefruit,
lemons, limes, and tangerines); and (3) increasing tolerances
for residues in or on peanuts from 0.02 to 0.05 ppm.

     In addition, the Agency is making the following
determinations:

     (1).  "grape pomace" in the 21 CFR should be changed to
     "grape pomace dried", the appropriate definition for
     this commodity.

     (2).  a tolerance proposal of 0.1 ppm or feeding and
     grazing restrictions must be proposed for cotton forage.

     (3).  Special Local Need registrations IFIFRA Sec. 24(c)]
     permitting the use of fenamiphos as broadcast soil
     applications to nonbearing nut trees and pears must be
     canceled or supported by residue data to determine the

             IV.  REGULATORY POSITION AND RATIONALE

 A.  REGULATORY POSITIONS AND RATIONALES

 Based on the review and evaluation of all available data  on
 fenamiphos the Agency has made the following determinations.
 Where it is the Agency's position that label revisions
 are needed in order for a product to remain in compliance
 with FIFRA, specific language is set forth in Section D
 of this chapter.

 1.  The Agency will not, at this time, initiate a Special
 Review [40 CFR Part 154] of fenamiphos.  After review and
 evaluation of the required studies for fish and wildlife  the
 Agency will reconsider the possibility of a Special Review.
 Acceptable protocols for conducting the avian, mammalian, and
 fish field studies must be submitted within six months  of
 the issuance of the standard and be accepted by the Agency
 before the initiation of field work.  Annual progress reports
 must also be submitted for the duration of the study.  The
 application rates used in these studies must be the lowest
 possible rates that are still efficacious as indicated  by
 the required efficacy data (refer to Regulatory Position  3).
 Rationale;  Fenamiphos is very highly toxic to birds
/I. 6 rag/kg) and mammals (LDso 2.7 mg/kg)  as well as to cold
 (LC5Q 72.1 ppb) and warm water (LCso 9.6 ppb) fish species.

 Estimated environmental concentrations (EECs) of the granular
 formulation of fenamiphos exceed the acute oral LDso for the
 most sensitive avian species tested, the bobwhite quail, and
 the estimated LDso values for 5 other avian species.  EECs
 also exceed the LDso for tne rat and the estimated LDso
 values for two other mammalian species.   EECs of the
 emulsif iable concentrate formulation indicate that fenamiphos
 residues exceed the calculated subacute  dietary LCso for four
 avian species.

 Field studies using both granular and spray formulations of
 fenamiphos according to label directions have shown some
 avian and mammalian mortality.  These studies also suggest
 that soil incorporation and/or irrigation immediately following
 application reduces hazards.  However, because of design
 deficiencies these studies do not meet guideline requirements;
 therefore, a terrestrial field study is  being required to
 determine if the hazards indicated by lab and field studies
 are below levels of concern for mammalian and avian species
 under actual use conditions.

-------
                                48
 Estimated environmental concentrations for water contaminated
 by aerial application to crops and for runoff exceed the
 LC5Q values for bluegill sunfish, and therefore, would cause
 significant adverse effects.  Thus, the following tests
 are being required to fully assess the potential exposure and
 toxicity of fenamiphos to aquatic environments: freshwater
 fish toxicity  (on EPs), freshwater invertebrate acute toxicity
 (using the technical and EPs), estuarine and marine acute
 toxicity, fish early life stage testing, fish life cycle,
 aquatic invertebrate life cycle, aquatic organism accumulation,
 and simulated and actual field testing of aquatic organisms.

 2.  The Agency is requiring restricted use classification
 for all fenamiphos formulated products.

 Rationale;  Fenamiphos exceeds the restricted use criteria
 set forth in 40 CFR 162.11(c)(2)(ii) and (iii).  Use of
 fenamiphos formulations has resulted in mortality to birds
 and mammals.  Fenaraiphos is acutely toxic to laboratory
 animals, Toxicity Category I, by the oral, dermal, and
 inhalation routes of exposure.  It is also very highly toxic
 to birds as well as cold and warm water fish species.  Use
 of fenamiphos exceeds the restricted use criteria for fish and
 wildlife; calculated residues exceed 1/5 the acute oral LD5Q
 for mammals, 1/5 the subacute dietary LCso for avian species, and
 1/10 the acute LCso for aquatic organisms.  In addition, use
 of fenamiphos has resulted in mortality to birds and mammals.
/Accordingly, the Agency has determined that the risks to
 humans, fish, and wildlife, associated with the unrestricted
 use of fenamiphos products, constitute unreasonable adverse
 effects.  Restricting the use of all fenamiphos products will
 reduce exposure and the potential for acute toxicity.  Field
 studies on birds, mammals, and aquatic organisms, are being
 required to determine actual exposure levels and potential
 hazard.

 3.  The Agency is requiring that efficacy data be submitted
 to support all currently registered application rates.

 Rationale;  EECs based on the maximum application rate exceed
 LD5Q values for birds and mammals and the LCso value for
 fish.  Therefore, the Agency is requiring that efficacy data
 be submitted within six months of the issuance of the standard
 to support the current application rates.  If such data
 indicate that rates could be lowered with minimal decrease in
 efficacy the Agency will require that all labels be revised
 to the lowest possible rates that are still efficacious.
 These labeling changes would reduce environmental concentra-
 tions of the pesticide while substantive data on the effects
 on fish and wildlife are being collected.

-------
                              49
4.  The Agency is requiring that all labels be revised as
follows:

     1). Directions for broadcast spray will be deleted
     for sites which currently have directions for both
     band and broadcast spray.

     2). All labels will prohibit the use of mist sprayers
     and will direct applicators to use only coarse sprays
     directed at the soil to reduce the possibility of
     spray drift.

     3). All labels will specifically prohibit aerial
     application.

Rationale;  As stated above, EECs based on the maximum
application rate exceed LDso values for mammalian and
avian species and the LCso value for aquatic organisms.
The above labeling changes would reduce environmental concen-
trations of the pesticide while substantive data on the
effects of fenamiphos on fish and wildlife are being collected.

5.  The Agency is requiring endangered species labeling
on fenamiphos EPs registered for use on cotton and soybeans
in accordance with Pesticide Registration (PR) Notice 87-5
(issued Hay 1, 1987). (Refer to Chapter IV, Section D of
/this document, for exact language.)

Rationale;  Fenamiphos was reviewed for endangered species
implications.  In order to protect endangered species from
harm, endangered species labeling is required.  (Refer to
Chapter III, Section C of this document, for a list of
the species).

6.  The Agency is unable to fully assess the environmental
fate of fenamiphos and is requiring the following studies:
photodegradation (air), anaerobic and aerobic soil metabolism,
leaching and adsorption/desorption, volatility (lab), soil
dissipation, rotational crops (confined and field), fish
accumulation, and spray drift studies.

Rationale;  Except for a hydrolysis study and a photodegradation
study in water, all the available environmental fate data do
not meet the guideline standards for acceptable testing.
These data are normally required under 40 CPR Part 158.130
and are necessary to assess the environmental fate and
transport and potential exposure to fenamiphos.

-------
                                50
7.  The Agency will evaluate the potential of fenamiphos
to contaminate ground water after  it has received and
evaluated additional required environmental fate data.

Rationale;  The potential for fenamiphos to reach ground
water cannot be determined at this time.  Some existing
studies, though deficient in some  respects, show it does
leach to some degree.  Additional  data are required to fully
assess the potential for fenamiphos to reach ground water.

8.  The Agency is unable to completely define the metabolism
of fenamiphos and to fully assess  its teratogenic potential;
therefore, the Agency is requiring the submission of a rat
metabolism study and teratology studies in two species.

Ratiojiale;  General metabolism and teratology studies
are normally required by 40 CFR Part 158.135 for products
with fenamiphos' use patterns.  There are currently no
metabolism studies or rat teratology studies available and
the available rabbit teratology study does not meet guideline
requirements.

9.  Available residue chemistry and toxicology data are
insufficient to permit the Agency to conduct a full tolerance
reassessment.

Rationale';  Data gaps exist for animal metabolism,  storage
stability* analytical methods, and magnitude of residues in
some raw agricultural commodities and processed food and
feed items.  Thus, upon receipt of the data required in
Table A, the Agency's conclusions with regard to the adequacy
of established tolerances are subject to change.

10.   The Agency is not requiring additional residue data
on the following raw agricultural commodities or proceseed
feed items;  brussels sprouts, cabbage, soybeans, grapefruit,
lemons, >imes, oranges, tangerines, dried citrus pulp, citrus
oil, citrus molasses, apples,  dried apple pomace, cherries,
peaches, grapes, raisins,  raisin waste, raspberries,
asparagus, cottonseed, okra, peanuts, and pineapples.

Rationale; The Agency has determined that the available
residue data adequately support the established tolerances
for these raw agricultural commodities.

-------
                             51
11.  The Agency is requiring English language translation
of product labels for garlici bananas, and cocoa beans
imported into the U.S.

Rationales  Insufficient documentation is available to
ascertain the adequacy of the established tolerances for
fenamiphos residues in or on garlic, bananas, and cocoa beans
imported into the U.S.  The Agency will be able to determine
from current English translation labels if overseas application
rates result in residues that exceed established tolerances.

12.  The Agency is requiring data to determine the pyrolysis
products of fenamiphos in tobacco products and the level of
residues in tobacco smoke.

Rationales Residue data previously submitted for residues of
fenamiphos in or on tobacco indicate that the combined
residues of fenamiphos and its sulfoxide and sulfone in or
on cured tobacco exceed 0.1 ppm following application at the
registered rate.  Therefore, the Agency is requiring these
data to. assess the human exposure to fenamiphos residues in
tobacco products.

13.  The Agency is; (1) reducing tolerances for residues in
or on Brussels sprouts and cabbage from 0.1 to 0.05 ppm,
(2) establishing a crop group tolerance of 0.5 ppm for
residues in or on citrus fruit (with a concomitant revocation
of the 0.6 ppm tolerance for residues in or on oranges,
grapefruit, lemons, limes), and (3) increasing tolerances for
residues in or on peanuts from .02 to .05 ppm.

Rationale: These actions will permit compatibility with
CODEX MRLs.

14..  The Agency is requiring the submission of residue data
supporting broadcast soil application of fenamiphos to
nonbearing nut trees and pears (FIFRA Section 24(c)).

Rationale;  The data are required to assess the current
non-food classification of this use.  Alternatively, the
registrant may cancel this use.

15.  The Agency is requiring a tolerance proposal of 0.1 ppm
for cotton forage.

Rationale;  Based on available data the Agency has
(Jetermined that a tolerance of 0.1 ppm would be appropriate.
Alternatively, the registrant may amend use directions
to include grazing and feeding restrictions for cotton forage.

-------
                               52
16.  The Agency is requiring reentry data for fenamiphos.
In order to maintain compliance with FIFRA an interim
48-hour reentry interval requirement for fenamiphos must
be placed on the labels of all fenamiphos end-use products
until the required data are submitted and evaluated and
any change in this interim reentry interval is announced.

Rationale;  Fenamiphos meets both the acute toxicity and
exposure criteria specified in 40 CFR 158.140 for reentry
data.  Until these data are received and evaluated an
interim 48-hour reentry interval will serve to reduce
exposure of field workers to this chemical.

17.  While data gaps are being filledf currently registered
manufacturing use products (MPs) and end use products (EPs)
containing fenamiphos as the sole active ingredient may be
sold, distributed, formulated and used, subject to the terms
and conditions specified in this Standard.  Registrants must
provide or agree to develop additional data, as specified in
the Data Appendices, in order to maintain existing regis-
trations.

Rationale:  Under FIFRA, the Agency does not normally cancel
or withhold registration simply because data are missing or
are inadequate (see FIFRA sec. 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.

            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 B2.

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

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

  Table A lists generic data requirements  applicable to all
products containing the pesticide subject  to this Registra-
tion Standard.  Table 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
formulator's exemption for that active ingredient.

  Table C lists product-specific data applicable to end use
products.

-------
                            61
B.  Manufacturing use products containing this pesticide
as one of multiple active ingredients are subject to:

     The data requirements listed in Table A.

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

     1.  The restrictions upon use, composition,  or
     packaging listed in Section IV.

     2.  If eligible for the forraulator's exemption3,  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:

     a.  If not eligible for the forroulator's  exemption,
     the date requirements listed in Tables A  and C.

     b.  If eligible for the formulator's exemption, the
     data requirements listed in Table C.
3 if you purchase from another producer and use as the
source of your active ingredient only EPA-registered products,
you are eligible for the formulator's exemption for generic
data concerning that active ingredient (Table A) and product-
specific data for the registered manufacturing use product
you purchase (Table 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.

                            62
       VI.  REQUIREMENT FOR SUBMISSION OF GENERIC DATA

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

A.  What are generic data?

     Generic data pertain to the properties or effects of a
particular active ingredient.  Such data are relevant to an
evaluation of all products containing that active ingredient
regardless of whether the product contains other ingredients
(unless the product bears labeling that would make the data
requirement inapplicable).

     Generic data may also be data on a "typical formulation"
of a product.  "Typical formulation" testing is often required
for ecological effects studies and applies to all products
having that formulation type.  These are classed as generic
data, and are contained in Table A.

B.  Who must submit generic data?

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

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

-------
                          63
     If you are not now eligible for a formulator's exemption,
you may qualify for one if you change your source of supply
to a registered source that does not share ownership in
common with your firm.  If you choose to change sources of
supply, the Confidential "Statement of Formula must identify
the new source(s) and you must submit a Formulator's Exemption
Statement form.

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

C.  What generic data must be submitted?

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

D.  How to comply with PCI requirements.

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

     1.  You will submit the data yourself.

     2.  You have entered into an agreement with one or more
registrants to jointly develop (or share in the cost of
developing) the data, but will not be submitting the data
yourself.  If you use this method, you must state who will
submit the data on which you will rely.  You must also provide
EPA with documentary evidence that an agreement has been
formed which allows you to rely upon the data to be submitted.
Such evidence may be:  (1) your letter offering to join in
an agreement and the othrer 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.

-------
                           64
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 requestthat EPA not suspend your registration
for non-compliance with the PCI.  EPA has determined that,
as a general policy,  it will not suspend the registration of
a product when the registrant has in good faith sought and
continues to seek to enter into a data development/cost
sharing program, but the other registrants developing the
data have refused to accept its offer.  [If your offer is
accepted, you may qualify for Option 2 above by entering
into an agreement to supply the data.]

     In order to qualify for this method, you must:

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

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

-------
                             65
      [Your company name] offers to share in the burden of
     producing the data required pursuant to FIFRA sec.
     3(c)(2)(B) in the  [name of active ingredient] Registration
     Standard upon terms to be agreed or failing agreement
     to be bound by binding arbitration as provided by FIFRA
     section 3(c)(2)(B)(iii).

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

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

     4•   You request awaiver 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
fail to submit the data.

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

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

                           66
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: 703-487-4650).

    Protocols approved by the Organization for Economic
Cooperation and Development (OECD) are also acceptable if
the OECD-recoramended 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 submittal 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

-------
                            67
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   t
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
roust 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).

I.  Existing stocks provision upon suspension or cancellation.

     The Agency has determined that if a registration is
suspended for failure to respond to a DC I 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

-------
                             68
such permission would be consistent with the Act.  The following
information must be included in any request for an existing
stocks provision:

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

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


   VII. REQUIREMENT FOR SUBMISSION OF PRODUCT-SPECIFIC DATA

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

     If you have a manufacturing use product, these data are
listed in Table B.  If you have an end use product, the data
are listed in Table C.

     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, F. and G.  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.

-------
                            69
    VIII.  REQUIREMENT FOR SUBMISSION OF REVISED LABELING

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

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

                                  73

                           TGUIDE-l

                       GUIDE TO TABLES

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

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

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

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

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

1.  Data Requirement (Column 1).  The data requirements are
listed in the order in which they appear in 40 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 naiied 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
     H
     I
Terrestrial, food
Terrestrial, non-food
Aquatic, food
Aquatic, non-food
Greenhouse, food
Greenhouse, non-food
Forestry
Domestic outdoor
Indoor
Any other designations will be defined in a footnote to the table,

                                74
                           TGUIDE-2

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

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

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

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

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

      egqs must be collected twice daily during the dosing period.  Animals must be sacrificed within 24  hours of  the
      final dose.  The distribution and identity of residues must be determined in milk, eggs, liver, kidney,
      muscle, and fat.
             <
3/    Samples from the studies requested above must also be analyzed using current enforcement methods to
      ascertain the validity of these methods.

4/    Should the metabolism of fenamiphos in ruminants or poultry be found to differ significantly from that
      in rats, additional swine metabolism studies will be required.

5/    Residues of fenamiphos sulfoxide (FSO) and fenamiphos sulfone (FSO2) in or on plant and animal commodities and
      of des-isopropyl fenamiphos, des-isopropyl fenamiphos sulfoxide and des-isopropyl fenamiphos sulfone in  animal
      commodities must be subjected to analysis by the multi-residue protocols.  Protocols for methods I,  II
      III, and IV are available from National Technical Information Service under Order No. PB 203734/AS.            CD

6/    Storage stability data providing definition of storage conditions and intervals under which the combined
      residues of fenamiphos, FSO, and FSO2 "ill remain stable in muscle, fat liver, kidney, milk, and eggs.

7/    The storage intervals and conditions of storage of samples used to support all established tolerances
      for residues of fenamiphos must be submitted.  If plant comrodity samples were frozen for > 3 years,
      these data must be accompanied by data depicting the percent decline in residues at the time and under
      the conditions specified.  On receipt of these data, the adequacy of the aforementioned tolerances
      will be reevaluated.

I/ For each end-use, the Registrant is required to propose an acceptable reentry interval based either upon;
   data on dissipation of residues (decline curve), human exposure to those residues,  and toxicity of
   the residues; or upon a determination of that time beyond which there are no detectable dislodgeable  or
   inhalable residues remaining in the worker/occupant environment. If the Registrant has. reason to  believe
   that an end-use will not cause exposure to residues, a request for waiver from this data requirement  should
   be submitted.

2/ Soil dissipation data are required only for uses where workers will be exposed directly to substantial
   quantities of soil during their work, e.g. for use on cotton where hand harvesting will be performed.

3/ Human exposure monitoring data nust be submitted if the Registrant wishes to use the "allowable exposure method" of
   determining reentry intervals.  If exposure studies are submitted, both dermal exposure and inhalation  exposure must
   be submitted.  If exposure studies are not submitted, human exposure (and reentry intervals) would  be estimated Erom
   dislodqeable residues as explained in Subdivision K.

 I/  The Agency will use acute toxicology data to satisfy this requirement.

 2/ Actual field testing with birds and manuals is required as per 40 CFR 158.145 with a typical granular formulation.
    Initial sites to be tested, based on application rates and wildlife usage information, include tobacco, citrus,  sod
    and turf (broadcast applications).  The application rates to be used are the lowest rates that are still
    efficacious as indicated by the required efficacy data (Appendix I, Table B, S 158.160).  Initial testing must include
    a stud/ of dietary exposure and thorough carcass searching to determine whether there is pesticide induced mortality,
    and if so, its extent.  Examination of the citrus use must also determine, by nest survey, whether avian breeding is
    disrupted, and collect complete natality, mortality, emigration, and immigration data.  It must be determined, by
    mark-recapture techniques, whether mammalian populations are also affected.  Also required is a field study of band
    application of the 15G formulation in fruit trees at 20 Ib ai/A, with carcass searching as above.  Multiple sites
    are required for all use patterns studied.  Additional field testing is reserved pending results of these studies
    and additional environmental fate testings.  Cancellation of any of the above use patterns would obviate the need
    for testing of these uses.  However, since further studies are pending the results of the above initial testing,
    other sites may be required to be substituted.  The Agency requires protocols for conducting the studies be submitted
    for review within 6 months of the issuance of the standard and accepted by the Agency prior to initiation of field
    work.  The study is due 48 months from publication of this Registration Standard but annual progress reports must be
    submitted for the duration of the study.  A guidance document is available from the Agency which outlines an        — *
    acceptable approach to these studies and the Agency encourages registrants to consult with Agency staff for assistance^
    if required.                                                                                                        ^

3/  Accepted studies were conducted on the 15G, but additional studies must be conducted on the
    35 and 21% spray concentrate products.  Estimated EECs from recommended application rates exceed
    the LC   values.
4/  Product is highly toxic fungicide and Estimated Environmental Concentrations (EECs) are likely to exceed 48-hour
    for the technical material.

5/  To support citrus, cotton, and peanut uses (crops exceeding 300,000 acres in coastal counties)
    and tobacco of which 56% is treated with fenamiphos.

6/  Test required because I£5Q values for warm- and coldwater fish species were less than 1 mg/L
    LC50 values.

T/  The Agency requires protocols for conducting the studies be submitted for review within 6 months of the issuance
    of the standard and accepted by the Agency prior to initiation of field work.  The study is due 48 months from
    publication of this Registration Standard but annual progress reports must be submitted for the duration of  the
    study.  A guidance document is available from the Agency which outlines an acceptable approach to these studies  and
    the Agency encourages registrants to consult with Agency staff for assistance,  if required.  The application rates
    to be used are the lowest rates that are still efficacious as indicated by the required efficacy data
     (Appendix T, Table n §158.160).

    Item 9A.  RESTRICTED USE CLASSIFICATION - PIPRA 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 40 CPR I62.11(c).  You will be notified of
the Agency's classification decision.

                                 112

                          SUMMARY-.*

     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
     CPR 162.10(h)(l)(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 1).  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.
1     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
     rereglstratlon, 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.

-------
                          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 nay 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 Disposal11 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 162.10]


                     COLLATERAL LABELING

    Bulletins, leaflets, circulars, brochures, data sheets,
flyers, or other written or graphic printed matter which is
referred to on the label or which Is to accompany the product
are termed collateral labeling.  Such labeling nay 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.

             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.

 There is  a section 3 10Z granular registration (#003125—00237, stamp dated
 Dec.  19,  1983), which is for  non-bearing fruit (deciduous fruit trees, in-
 cluding apples, cherries and  peaches).  It restricts the use of any fruit
 forming on trees until one year after treatment.  Likewise there are SLK
 (special  local meed,  24C registration) registrations, 30 in all, of a
 similar mature.  These are as follows:

There is, however, a  section  3 (101 granular) registration label (stamp
dated July  22, 1983) which is for fruit crop (including apples, cherries
and peaches) which has a FBI  (pre-harvest interval) of 72 day for bearing
apples end  45 days for bearing cherries and peaches.  There are also other
section 3 registrations for feaamlphos (a 15X granular bearing stamp dated
Kay 6, 1985 and a 3 pound per gallon EC bearing stamp date July 25, 1985)
which are for bearing apples, cherries and peaches having FBI's of 72 and
45 days respectively.  Xt is my judgement (Mr. E*nry Jaeoby, FM 21 team
leader also agrees) that the accepted registrations on bearing fruit trees
(apples, cherries and peaches) with FBI's of 72 and 45 days, lift or coun-
termand the one year FBI restriction on the non-bearing deciduous fruit
trees.  The index entry for fenamiphos has been written to reflect this
decision.

Vote:  Since there ere mow section 3 registrations to cover all the SLR
registrations listed shove, it seems that it would be a prudent action to
get these off our books.

                            BIBGUIDE-l

              GUIDE TO USE OF THIS BIBLIOGRAPHY
1.  CONTENT OP 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
1   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)(J|) 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 the Agency could confidently identify
    one, ithe 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 marks, the Agency took It directly
    from the document.  When a four-digit date Is followed
    by a question mark, the bibliographer deduced the
    date from evidence in the document.  When the date
    appears as (19??)* the Agency was unable to determine
    or estimate the date of the document.

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

d.  Trailing Parentheses.  For studies submitted to the
    Agency in the past, the trailing parentheses include
    (in addition to any self-explanatory text) the 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 123^56, the
         first study would be 123456-A; the second, 123*56-
         B; the 26th, 123^56-Z; and the 27th, 123U56-AA.

EPA Product Registration Number: 	

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

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

    (2)  My firm requests that EPA not suspend the registration of our product,
despite our lack of Intent to submit the generic data In question, on the grounds
that the product contains the active Ingredient solely as the result of  the
Incorporation Into the product of another product which contains that active
ingredient, which is registered under PIFRA Section 3* and which is purchased by
us from another producer.

    (3)  An accurate Confidental Statement of Fbrmula(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 Pom No. 857(M.  The
registered source(s) of the above named active Ingredient In my product(s) Is/are
	                      and their registration number(s) is/are _____________ •

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

    00  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 falls to comply with
the undertakings made In this Statement, my firm's product's registration may be
suspended under FIFRA Section 3(c)(2)(B).

    (5)  I further understand that if my firm is granted a generic data  exemption
for the product, my firm relies on the efforts of other persons to provide the
Agency with the required generic data.  If the registrant(s) who have committed
to generate and submit the required data fall 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.
