CERTIFIED MAIL
Dear Registrant:

       I am pleased to announce that the Environmental Protection Agency has completed its
reregistration eligibility review and decisions on the pesticide chemical case fosamine
ammonium. The enclosed Reregistration Eligibility Decision (RED) contains the Agency's
evaluation of the data base of this chemical, its conclusions of the potential human health and
environmental risks of the current product uses, and its decisions and conditions under which
these uses and products will be eligible for reregistration.  The RED includes the data and
labeling requirements for products for reregistration.  It may also include requirements for
additional data (generic) on the active ingredients to confirm the risk assessments.

       To assist you with a proper response, read the enclosed document entitled "Summary
of Instructions for Responding to the RED".  This summary also refers to other enclosed
documents which include further instructions.  You must follow all instructions and submit
complete and timely responses. The first set of required responses are due 90 days from
the date of this letter.  The second set of required responses are  due  8 months from the
date of this letter.  Complete and timely responses will avoid the Agency taking the
enforcement action of suspension against your products.

       If you have questions on the product specific data requirements or wish to meet with
the Agency, please contact the Special Review  and Reregistration Division representative
Frank Rubis at (703) 308-8184.  Address any questions on required generic data to the Special
Review and Reregistration Division representative Shanaz Bacchus at (703) 308-8065.

                                                     Sincerely yours,
                                                     Louis P. True, Jr., Acting Director

              SUMMARY OF INSTRUCTIONS FOR RESPONDING TO
             THE REREGISTRATION ELIGIBILITY DECISION (RED)

1.  DATA CALL-IN (PCI) OR "90-DAY RESPONSE"  If generic data are required for
reregistration, a DCI letter will be enclosed describing such data.  If product specific data
are required, another DCI letter will be enclosed listing such requirements.  If both generic
and product specific data are required, a combined Generic and Product Specific letter will
be enclosed describing such data.  Complete the two response forms provided with each DCI
letter (or four forms for the combined) by following the instructions provided. You must
submit the response forms for each product and for each DCI within 90 days of the date
of this letter (RED issuance date); otherwise, your product may be suspended.

2.  TIME  EXTENSIONS AND DATA WAIVER REQUESTS  No time extension requests
will be granted for the 90-day response.  Time extension requests may be submitted only with
respect to actual data submissions. Requests for data waivers must be submitted as part of the
90-day response. Requests for time extensions should be submitted in the 90-day response,
but certainly no  later than the  8-month response  date.  All data waiver and time extension
requests must be accompanied by a full justification. All waivers and time extensions must be
granted by EPA in order to go into effect.

3.  APPLICATION FOR REREGISTRATION OR "8-MONTH RESPONSE"  You must
submit the following items for each product within eight months of the date of this letter
(RED issuance date).

      a.  Application for Reregistration (EPA Form 8570-1).  Use only an original
application form. Mark it "Application for Reregistration."  Send your Application for
Reregistration (along with the other forms listed in b-e below) to the address listed in item 5.

      b.  Five copies of draft labeling which complies with the RED and current regulations
and requirements.  Only make labeling changes which are required by the RED and current
regulations (40 CFR 156.10) and policies. Submit any other amendments (such as formulation
changes, or labeling changes not related to reregistration) separately. You may delete uses
which the RED says are ineligible for reregistration. For further labeling guidance,  refer to
the labeling section of the EPA publication "General Information on Applying for Registration
in  the U.S., Second Edition, August 1992" (available from the National Technical Information
Service, publication #PB92-221811;  telephone number 703-487-4650).

      c.  Generic or Product Specific Data.  Submit all data in a format which complies
with PR Notice 86-5, and/or submit citations of data already submitted and give the EPA
identifier (MRID) numbers. Before citing these studies, you must make sure that they meet
the Agency's  acceptance criteria (attached to the DCI).

      d.  Two copies of the  Confidential Statement of Formula (CSF) for each basic and
each alternate formulation. The labeling and CSF which you submit for each product must
comply with P.R. Notice 91-2 by declaring the active ingredient as the nominal
concentration.  You have two options for submitting a CSF:  (1) accept the standard certified

-------
limits (see 40 CFR §158.175) or (2) provide certified limits that are supported by the analysis
of five batches. If you choose the second option, you must submit or cite the data for the five
batches along with a certification statement as described in 40 CFR §158.175(e). A copy of
the CSF is enclosed; follow the instructions on its back.

      e. Certification With Respect to Data Compensation Requirements. Complete and
sign EPA form 8570-31 for each product.

4. COMMENTS IN RESPONSE TO FEDERAL REGISTER NOTICE  Comments
pertaining to the content of the RED may be submitted to the address shown in the Federal
Register Notice which announces the availability of this RED.

EXECUTIVE SUMMARY

       The Agency has conducted risk assessments of the current uses of fosamine ammonium
pesticide products and has determined that those uses of fosamine ammonium, as specified in
this document, will not cause unreasonable risk to humans or the environment, and are eligible
for reregistration.

              Fosamine ammonium is a herbicide/plant growth regulator that is used for
brush control of nonagricultural rights-of-way (e.g., highways, railroads, and utilities),
industrial sites, and fencerows. The pesticide can be applied once from spring to  early fall by
aircraft, backpack or handwands.  It is prohibited from use in irrigation systems.  When the
pesticide is applied  in one year, its brush control effects are  achieved by inhibiting bud growth
the year following the application. Fosamine ammonium is  not registered for application to
croplands and soils  treated with this herbicide cannot be converted to food/feed croplands
within one year of treatment.  According to the current label, fosamine ammonium is not
registered for sale or use in California and  Arizona.  A product registered for forest planting
sites has been canceled (June 22,  1994), and the current uses on aquatic sites are being
voluntarily deleted from the sole product registration.

       The health and environmental effects data bases indicate a low level of toxicity of this
pesticide. Fosamine ammonium is not very persistent and degrades rapidly in most soils.
Data provided to support estimates of acute and chronic exposure and risks to mammalian
species, other vertebrates and invertebrates are sufficient for reregistration purposes.

       Fosamine ammonium is currently classified as a Toxicity Category II chemical on the
basis of acute dermal toxicity studies in mammalian species.  Adequate data have been
submitted in support of worker exposure.  There are  no special toxicological concerns for  this
plant growth regulator which warrant the establishment of minimum or baseline active-
ingredient-based personal protective equipment (PPE) for handlers.

       The Agency is requiring the submission of additional generic data to confirm its
scientific conclusions for fosamine ammonium.  These confirmatory data requirements include
(i) method validation for a worker exposure study; (ii) certification of limits of the technical
grade active ingredient; (iii) a cytogenetics assay; (iv) spray drift characterization; (v)  an avian
reproduction study in mallards; and (v) data or further information to clarify effects on non-
target plants.

       Before reregistering the products containing fosamine ammonium, the Agency  is
requiring that product specific data, revised Confidential Statements of Formula (CSF) and
revised labeling  be submitted within eight months of the issuance of this document. These  data
include product chemistry for each registration and acute toxicity testing.  After reviewing
these data and any revised labels and finding them  acceptable in accordance with Section
3(c)(5) of FIFRA, the Agency will reregister a product.  Those products which contain other
active ingredients will be eligible for reregistration only when the other active ingredients are
                                           VI

I.      INTRODUCTION

       In 1988, the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA) was amended
to accelerate the reregistration of products with active ingredients registered prior to November
1,  1984. The amended Act provides a schedule for the reregistration process to be completed in
nine years. There are five phases to the reregistration process. The first four phases of the process
focus on identification of data requirements to support the reregistration of an active ingredient
and the generation and submission of data to fulfill the requirements. The  fifth phase is a review
by the U.S. Environmental Protection Agency (referred to as "the Agency") of all data submitted
to support reregistration.

       FIFRA Section 4(g)(2)(A)  states that in Phase 5  "the Administrator shall determine
whether pesticides containing such active ingredient are eligible for reregistration" before calling
in  data  on products  and either reregistering products or  taking  "other appropriate regulatory
action."  Thus, reregistration 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"  criterion of FIFRA.

       This document presents the Agency's decision regarding the reregistration eligibility of
the registered uses of fosamine ammonium. The document consists of six sections.  Section I is
the introduction. Section II describes  fosamine  ammonium, its uses, data requirements and
regulatory history. Section III discusses the human health and environmental assessment based on
the data available to the Agency.  Section  IV presents the reregistration decision for fosamine
ammonium.   Section  V  discusses the reregistration requirements for  fosamine ammonium.
Finally,  Section VI  is the Appendices which support this Reregistration Eligibility Decision.
Additional details concerning the Agency's review of applicable data are available on request.

              analyzed in this RED document, and all outstanding data to support
              the  continued registration of these sites are listed in this RED
              document. The Agency is processing the registrant's request to
              amend  the label to delete these  use sites.  If, in the future, the
              registrant wishes to register aquatic sites, the registrant will have to
              resubmit all data  to support those uses.

       Use Practice Limitations:   Do  not apply directly to water, or  areas where
                                  surface water is present, or to intertidal areas below
                                  the  mean high water mark.  Do not contaminate
                                  water when disposing of equipment washwaters.

                                  Do  not use on  food crops.   If areas  previously
                                  treated with fosamine ammonium are converted to
                                  cropland, do not plant food crops or graze livestock
                                  within  1  (one) year of treatment.   However,
                                  nonfood/feed plants such as wild flowers and native
                                  grasses, may be planted at any time after treatment
                                  on the sites listed above.

                                  Do not apply through irrigation system.

                                  Do  not  cut treated brush until stems are dead, or
                                  sprouting may occur.

                                  Not  registered for sale or use  in California and
                                  Arizona on the current registered label.
C.     Data Requirements

       Data required in the Data Call-in (DCI) Notice (9/30/91) for fosamine ammonium
included studies on ecological effects, environmental fate, product chemistry, toxicology
and occupational and residential  exposure.  These data were required to  support the
registered uses. Appendix B includes all data requirements identified by the Agency for
currently registered uses needed to support reregistration.
D.     Regulatory History

   Fosamine ammonium was first registered on July 7, 1975, under EPA Registration No.
352-376 (Du Pont Krenite® Brush Control Agent).  It was registered for non-cropland
(non-food) use areas such as railroads, pipeline, utility  and highway right-of-ways,
reforestation areas, drainage ditch banks, storage areas, industrial plants sites,  and other
similar sites.  However, the registrant requested voluntary cancellation of this product
which was effective on June 22, 1994.

       A  second product, (EPA Reg.  No.  352-395),  was registered on May 2, 1980.
Currently, this product is registered under two trade names, Du Pont Krenite® S Brush

-------
       Control Agent and Du Pont Krenite® UT Brush Control Agent. This formulated product
       also contains 41.5% active ingredient, ammonium salts of fosamine.  The uses, except for
       forest planting sites, are the same as for the original product.

             On August 23,  1994,  Du Pont filed an Application for Amended Registration,
       requesting voluntary cancellation of direct applications to water, ditchbanks, and to other
       sites which are adjacent to and surrounding domestic  water, supply reservoirs, supply
       streams,  lakes and  ponds.  The  Agency is  processing this request, which includes
       publishing a Notice of Intent to delete these uses in the Federal Register.  There will be
       a ninety  (90) day comment period.  Because there are no other  current registrants and
       there are outstanding environmental data requirements to support continued registration
       of these uses, the Agency does not anticipate Du Pont or any other party choosing to retain
       these  uses.  Therefore, the Agency presumes that these sites will be deleted  from the
       current label by late 1994.

             For this reason and the fact that there are outstanding data requirements for these
       sites,  the Agency has excluded the risk assessment of aquatic  sites in its decision to
       reregister fosamine ammonium. Consideration of the aquatic uses for future registration
       must include all applicable data requirements.
III.    SCIENCE ASSESSMENT

       A.    Physical Chemistry Assessment

             Fosamine ammonium is a monoammonium salt of phosphonic acid containing an
       aminocarbonyl group and a monoethyl ester. It is formulated as a soluble concentrate
       liquid end-use product (EP)  containing 41.5% of the active ingredient (a.i.).   Technical
       fosamine ammonium exhibits the following characteristics:

B.     Human Health Assessment

             Below is a summary  of the toxicology and occupational and residential
       exposure data bases reviewed by the Agency for the  purpose of determining the
       reregistration eligibility of fosamine ammonium.  Data bases for chronic feeding
       studies,  carcinogenic, metabolic and reproductive  toxicological  endpoints are
       conditionally required for the current use pattern of the pesticide, under conditions
       specified in 40 CFR §158.340.
       1.     Toxicology Assessment
             a.     Acute Toxicity

                    Acute studies for oral, dermal, and  inhalation endpoints, which
             were based  on  a  42% technical  grade  active  ingredient  (TGAI),
             demonstrated low potential  toxicity  for fosamine ammonium.  For the
             RED, oral, dermal and inhalation exposures were evaluated on the basis of
             the Toxicity Categories IV, II and IV, respectively,  as shown in Table I.
             Similarly, studies with  the 42% formulation indicated low potential for
                                    6

-------
primary dermal irritation and primary eye irritation.  Fosamine ammonium
does not appear to be a dermal sensitizer.  All data requirements for acute
oral, dermal, inhalation, dermal irritation and eye irritation toxicological
endpoints are satisfied.

       There were no clinical signs of acute delayed neurotoxicity observed
in hens at doses of 2000 mg/kg/day.  However, there were some perineural
lymphoid proliferations of the tibial nerve in both the positive control and
treated  group, but not in the  vehicle control group.  Although these
proliferations may be unrelated to the degenerative changes observed in the
positive control group, their presence in  both treated and control groups
indicates equivocal results (MRID 42934801).

       In an acute mammalian neurotoxicity study, rats were dosed by
gavage with 0, 500, 1000 or 2000 mg/kg/day of fosamine ammonium.  The
systemic  NOEL from this study was considered to be 500 mg/kg, while the
LEL, based on diarrhea,  was 1000 mg/kg.  Possible neurotoxic effects
were observed, but not statistically significant at 1000 and 2000 mg/kg.
These were slight palpebral closure, irregular respiration, both observed
in the open arena.   Ample positive control data were provided on
amphetamine,  acrylamide, carbaryl and DDT.

                    b.     Subchronic Toxicity

                           Subchronic oral studies

                           Subchronic feeding data are only conditionally required for the
                    fosamine ammonium use pattern if the intended use is expected to result in
                    human exposure  to the product via the oral route and if the expected
                    exposure is over a limited portion of the human lifespan, yet is significant
                    in terms of the frequency of exposure, magnitude of exposure, or the
                    duration of exposure.   Due to  concern  for potential drinking  water
                    contamination from the use of  fosamine ammonium around reservoirs,
                    subchronic feeding data in two  species were required.  Both subchronic
                    feeding studies in rodents (MRID 00075736)  and nonrodents (MRID
                    42867001) deviate somewhat from the guidelines.  However, the combined
                    data from the two studies are sufficient to fulfill the regulatory requirement
                    for subchronic feeding data.

-------
       Fosamine ammonium was tested in a 90-day feeding study in rats
at 0,  200,  1000 or  5000/10000 ppm in the diet (0,  10, 50, 250 or 500
mg/kg/day). At the highest dose level, the animals received 5000 ppm for
8 weeks and then 10000 ppm for weeks 9 through 13. The NOEL is 200
ppm.   The LOEL  is 1000  ppm based on:  (a) swollen deep proximal
convoluted tubules of the kidney in males at 1000 ppm and above, and (b)
on vacuolated  and degeneratively affected deep proximal convoluted tubules
of the kidney,  epithelial hyperplasia  of the urinary bladder and slight
decreases in body weight, body weight gain and food consumption in males
at 5000/10000  ppm.  The  biological meaning of the  kidney effects is
unknown.  Although this study was accepted, it was considered incomplete
because of (i) the lack of data on dietary analyses; (ii) lack of individual
animal data for clinical signs, body weight, food consumption and organ
weights; (iii)  the small number of tissues microscopically examined; and
(iv) the lack of adequate  examination  of the low- and mid-dose animals
(MRID 00075736).

       In another subchronic feeding study, fosamine ammonium was fed
to dogs for 6  months at 0, 200, 1000 or 5000/7500/10000 ppm (0, 5, 25
and 125 or  187.5 or 250 mg/kg/day). At the highest dose level, the dogs
received 5000 ppm  for the first week  and 7500 ppm for the second and
third weeks. Beginning at the fourth week, the dogs received  10000 ppm
in the diet. Four males and four females were tested at each dose level.
There was a statistically significant increase in serum glucose in high-dose
female dogs when compared to controls at 2 and 6 months. This increase
was attributed  to the values from  one  dog  in the group.   No other
treatment-related effects were observed. The NOEL is 5000/7500/10000
ppm (HDT). Although this study was accepted, it is considered somewhat
incomplete because the dogs were 14-16 months old at the start of the
study, rather than 4-9 months old,  and therefore, the  effects on young
animals  could  not be  evaluated  in  the  study (MRID42867001).
Nevertheless, results from these two studies are sufficient to characterize
the potential  subchronic toxicity from mammalian  oral exposure to  the
pesticide.
Subchronic Dermal

       An  acceptable 21-day dermal study is available.  In this study,
fosamine ammonium was tested in male and female rabbits at 0,  50, 500
or 1500 mg/kg/day.  The test material was applied as a paste  in deionized
water for 6  hours/day for 21 or 22 consecutive days.  Intermittent minimal
dermal irritation was observed in  all groups in both  male and female
rabbits.  Although  mild erythema  was observed more  often in  the test
                       9

-------
groups than in the controls, it was not clearly related to exposure to the test
material.  The NOEL is therefore considered to be 1500 mg/kg/day (HDT)
(MRID 41998101).

Subchronic mammalian neurotoxicity

      In a subchronic mammalian neurotoxicity study in rats, fosamine
ammonium was tested at 0, 5000, 10000 or 20000 ppm in the diet for 96-
98 days (calculated to be 299, 604 or 1193 mg/kg/day for males and 398,
779 or 1567 mg/kg/day for females).  The NOEL for systemic effects is
below 299 mg/kg/day.  The LEL is 299 mg/kg/day, based on diarrhea in
males at all dose levels and in females at 1567 mg/kg/day in females.
There were no neurotoxic effects at any dose level.  Ample positive control
data were provided on amphetamine,  acrylamide, carbaryl  and DDT.
These data were considered acceptable (MRID 42946502).
c.      Developmental Toxicity

       Fosamine ammonium was tested in Crl:CD®BR rats at the following
dose levels: 0, 50, 350,  1000 or 3000 mg/kg/day.  The test material was
administered by gavage on days 7-17 of gestation. The maternal NOEL is
1000 mg/kg/day and the maternal LEL is 3000 mg/kg/day based on clinical
signs of toxicity (diarrhea) and on decreases in body weight gain and food
consumption during the dosing period. The developmental NOEL is 3000
mg/kg/day (HDT)  (MRID 42320901).
d.     Mutagenicity

       Mutagenicity studies  include: (1) gene  mutation assay in S.
typhimurium (MRID 41891601);  (2) CHO/HGPRT assay for gene mutation
(MRID 00148267); (3)  in vivo bone marrow cytogenetic assay in rats
(MRID 00147636); (4) in vitro  assay for chromosome  aberrations in
Chinese  hamster  ovary~(CHO) cells   (MRID  00147635);  and  (5)
unscheduled DNA synthesis/rat  hepatocytes in vitro (MRID 00147634).

       All  of the  studies  were classified as  acceptable except for the
unscheduled DNA synthesis study (UDS) in rat hepatocytes,  which was not
tested at high enough dose levels. The  in vitro assay for chromosome
aberrations in CHO cells was strongly positive, whereas all the other four
assays were  negative.   Although  the  UDS  study  was  classified as
unacceptable,  according to the new mutagenicity testing requirements, the
basic regulatory requirement for a mutagenicity battery is satisfied by the
                      10

-------
studies that were conducted.  The new battery consists of the following
studies: a gene mutation assay in S. typhimurium, an in vivo bone marrow
cytogenetic assay, and a mouse lymphoma assay or a CHO/HGPRT assay
for gene  mutation in conjunction with an in vitro  assay for chromosomal
aberrations in Chinese hamster ovary  (CHO)  cells.  These studies have
already been conducted. The basic mutagenicity study battery requirements
are fulfilled.  However, clastogenic (chromosome  breakage) effects in the
Tier I studies trigger the need for additional confirmatory data. Based on
the strong clastogenic effect in the cultured CHO cells, the Agency requires
additional testing with germ cells as a follow-up, confirmatory study. This
testing requirement can be satisfied  with  such  assays as  an in vivo
cytogenetics assay in spermatogonia/spermatocytes or a micronucleus assay
with spermatids.
(i)  Gene mutation assay in S. typhimurium

       Fosamine ammonium was tested for the potential to induce reverse
mutations in Salmonella typhimurium strains TA97, TA98, TA100  or
TA1535 using the plate  incorporation  assay,  both with and  without
metabolic activation.  The dose levels selected ranged from  10  to 5000
jig/plate.  The results were negative.
(ii)  CHO/HGPRT assay for gene mutation

       Krenite (41.5% formulation) was tested for the potential to induce
forward mutations in Chinese hamster ovary cells (CHO/HGPRT assay) up
to levels  of cytotoxicity, both with  and without metabolic activation.
Krenite was not mutagenic in this assay.

(iii)  Cytogenetic assay

       Single oral  doses of Krenite  (0, 1,  3  or 10  grams/kg) were
administered by gavage in rats in an in vivo bone marrow study.  Krenite
did not induce an increase in the frequency of chromosomal aberrations at
any dose level.
Chromosome aberrations in Chinese hamster ovary (CHO) cells

       In an in vitro assay for chromosome aberrations in Chinese hamster
ovary  (CHO) cells,  Krenite  was tested at  levels up to cytotoxicity.
Statistically significant,  dose-related increases in structural chromosome
                       11

-------
       aberrations were observed at 16.7 and 33.3 jiL/ml Krenite in nonactivated
       cultures, as well as at 15, 30 or 33.3 jiL/ml in S-9 supplemented cultures.
       Under the conditions of the assay, Krenite was clastogenic both with and
       without metabolic activation.  Chromosome breakage was observed at final
       concentrations (v/v, in medium) of Krenite equivalent to:
                     1.4%, 2.8%, or 5.7% (with metabolic activation);
                     1.6% or 3.2% (without metabolic activation)
       Unscheduled DNA synthesis/rat hepatocytes in vitro.

             To determine unscheduled DNA synthesis, the EP was tested in an
       in vitro assay in rat hepatocytes at 8 halflog concentrations ranging from
       1 x 10 5 mM to 10 mM.  There was no positive response in two separate
       trials for induction of unscheduled DNA (repair) synthesis as judged by a
       net increase of 5 silver grains or more per nucleus. In these assays, the EP
       tested negatively for UDS  induction in rat hepatocytes. However, 10 mM
       (the highest dose  tested)  is equivalent to 1.7 mg product/ml or 0.88 mg
       a.i./ml. The limit dose for this assay is 5 mg ai/ml.  Therefore, the study
       was not conducted at a sufficiently high dose level for an adequate negative
       result.
       e.      Reference Dose

              There is no food use pattern for fosamine ammonium.  For potential
       future food use, the Reference Dose (RfD) is 0.01 mg/kg/day, based on the
       NOEL of 10 mg/kg/day from the rat subchronic study with an uncertainty
       factor of 1000.

2.     Exposure Assessment

       a.      Dietary Exposure

              Since there are no registered food uses for fosamine ammonium, no
       dietary exposure is expected.  Dietary exposure data are not required.

       b.      Occupational and  Residential
             There is a potential for handler exposure to the herbicide during
       open/pour mixing and loading, and applications by air, backpack and high
       pressure/volume hand wands. Fosamine ammonium is a Toxicity Category
       II chemical for acute dermal exposure (LD50  > 1682 mg/kg). The other
                              12

-------
toxicological endpoint which was used in this assessment is  Toxicity
Category IV for acute inhalation toxicity (see Table 1).
Mixer/Loader/Applicator (Handler) Exposure:

       Chemical specific mixer/loader/applicator data have been submitted
to EPA.  Estimates of the units of daily dermal  and inhalation handler
exposure were  obtained from MRID No. 42598101 and the Pesticide
Handlers Exposure Database (PHED ver. 1.01).  Exposure scenarios are
presented  in Table 2 along with the corresponding exposure  assessment.
M/L/A exposure estimates are based on the use of the fosamine ammonium
end-use-products (EP) at the maximum label rates.

       The daily maximum acreages treated are assumed to be: 2 acres by
backpack,  10 acres by high pressure handwand,  and 350 acres  by air.
Worker exposure estimates are  based on the assumption that workers wear
long pants, long sleeve shirt, shoes, and socks, and no gloves, except for
workers using backpacks (Scenario V) who are assumed to wear chemical
resistant gloves.

       The major route of worker exposure is dermal which  is estimated
to range from 0.3 mg/kg to 9.0 mg/kg during an eight hour work day.
Inhalation exposure for the same time  frame is estimated to be negligible.

       3.     Risk Assessment

             a.     Dietary

                    There  are no registered food uses for fosamine ammonium.   A
             dietary risk assessment is not required for the current fosamine ammonium
             use pattern.


             b.     Occupational and Residential

                    Fosamine ammonium is considered to be in Toxicity Category IV
             for acute oral and inhalation toxicity, and Category II for acute dermal
             toxicity.  The dermal effects observed in rabbits and guinea pigs after acute
             or subchronic dermal exposure at the  highest doses tested were either
             intermittent dermal irritation or at most mild erythema.  Currently, there
             are no toxicity concerns for short term (1 to 7 days) or intermediate term
             (1 week to several months) occupational  exposure.  The NOELs identified
             in the rat acute neurotoxicity study (500 mg/kg), the developmental toxicity
             study (3000 mg/kg/day)  and the 21 day dermal study  (1500 mg/kg/day)
             were very  high and thus trigger no  risk concern based  on  expected
             exposure.

                    For this use pattern of fosamine ammonium, the estimated exposure
             of commercial mixer/loader/applicators is likely to reflect the worse case
             scenario.  However, there are no known significant  acute or chronic
             toxicological endpoints that warrant the establishment of risk mitigation
             measures to any category of handlers  of the pesticide.  Clothing  as
             described in the exposure assessment will provide adequate protection to
             handlers.
C.     Environmental Assessment

       1.     Environmental Fate
             Available environmental fate data support a qualitative environmental fate
       assessment of  fosamine  ammonium.    Fosamine  ammonium  dissipation  is
       predominantly dependent  on rapid,  microbial  mediated degradation.   Major
       degradates  of fosamine  ammonium  are carbamoylphosphonic acid  (CPA),
       carboxylphosphonic acid (ING-3003), and carbon dioxide (C02). However, no
       definitive  environmental  fate data  are  available for  CPA  and  ING-3003.
       Additionally, this environmental fate assessment excludes the aquatic sites, due to
                                    15

-------
the lack of applicable data, namely aerobic aquatic and aquatic field dissipation
studies, and the registrant's desire to remove them from the product label.
       a.     Environmental Chemistry, Fate and Transport

             (1)    Hydrolysis

       Fosamine ammonium is stable  to hydrolysis.   Radiolabeled fosamine
ammonium, at 9.2 to 10.3 jig/ml, did not hydrolyze in sterile, buffer solutions at
pH 5,7, and 9  (MRID 40133701).

             (2)    Photodegradation in water, soil and air

       Radiolabeled fosamine ammonium also did not photodegrade in irradiated
pH 9  buffer solution  and  Keyport silt loam  soil.   The  requirements  for
photodegradation in water and soil have been satisfied.  The data to support the
photodegradation in air were waived because fosamine ammonium volatilization
from soil does not appear to be a major route of dissipation. Fosamine ammonium
also  has a low  vapor  pressure of 4.6  x 106 mm Hg  as  reported in  MRIDs
40133702  and 40133703.

             (3)    Aerobic and anaerobic soil metabolism

       Fosamine ammonium dissipation is predominantly dependent on rapid,
microbial-mediated degradation.  Radiolabeled fosamine ammonium, at 10 |ig/g,
had a first-order degradation half-life of  0.5 days (k= 1.441  days *) in an aerobic
Delaware  silt loam soil.  Supplemental  soil  metabolism data indicate fosamine
ammonium had a half-life of  1.2 weeks in aerobic silt loam and sandy loam soil.
Degradates of fosamine ammonium were CPA (94 percent of applied immediately
posttreatment), IN-G3003 (26 percent of applied 1  month posttreatment), and C02
(33 percent of applied).

       Radiolabeled fosamine ammonium had a  half-life of 4 days in anaerobic
sediment and pond water from Meyersville, Maryland.  Radiolabeled fosamine
ammonium  was  stable in  sterile,  anaerobic  sediment  and water samples.
Degradates of fosamine ammonium were CPA (59 percent of applied at 14 days
posttreatment), ING-3003 (43 percent of applied at 9 months posttreatment), and
C02  (7.6   percent  of  applied)   (MRIDs  42060601,  42724301,  42060602,
42680701).
                             16

-------
              (4)    Anaerobic aquatic metabolism

       Data indicate fosamine ammonium degradation in anaerobic environments
is  a rapid,  microbial-mediated  process.   Anaerobic aquatic studies  provide
marginally acceptable data on the metabolism of fosamine ammonium in anaerobic
aquatic environments.

       As  described above  in the  section on anaerobic  soil metabolism,
radiolabeled fosamine ammonium, at 10 |ig/g, had a half-life of 4 days (k = 0.156
days1) in Meyersville, MD sandy loam sediment and pond water.   Fosamine
ammonium was stable in sterile sediment and pond water.  Radiolabeled residues
in  sediment extracts were parent fosamine  ammonium (104 percent of applied
immediately posttreatment), carbarnoylphosphonic acid  (59 percent of applied
fosamine ammonium at 14 days posttreatment), and carboxylphosphonic acid (43
percent of applied fosamine ammonium at 9 months posttreatment).  Radiolabeled
residues in the potassium hydroxide traps were identified as C02 (7.6 percent of
applied fosamine ammonium at 12 months posttreatment).  Radiolabeled residues
were  also detected  (less than 15  percent of applied  fosamine ammonium) in
nonextractable sediment organic matter.  The anaerobic aquatic metabolism data
requirement is satisfied (MRIDs 42060602 and 42680701).
              (5)    Leaching and adsorption/desorption

       Based on limited data, fosamine ammonium appears to be very mobile in
sandy  loam soil.  A batch equilibrium study provides acceptable data on the
binding affinity of fosamine ammonium in sandy loam soil.  The  reported data
indicate that fosamine ammonium should be very mobile in sandy loam soil, with
a Freundlich adsorption coefficient of 0.066 ml/g (l/n = 0.8603; Koc = 8.087
ml/g).  A simple desorption coefficient (Kdes) was greater than 16 ml/g.

       Although the unaged portion of the batch equilibrium/soil column leaching
is  not fulfilled at this  time,  the  weight of  evidence  from acceptable and
supplemental mobility  data indicate that fosamine ammonium has a very low
binding affinity to sandy loam and silt loam textured soils.  No additional mobility
data are needed to assess the mobility of fosamine ammonium (parent) at this time.
The aged residues portion of the Guideline 163-1 data requirement, to address
mobility of the individual degradates,  has not been satisfied (MRIDs 42492401,
42492301).

              (6)    Field volatility

       Fosamine ammonium has a low vapor pressure  (4.6 x 106 mm  Hg).
Therefore, the data requirement for a field volatility study  (Guideline 163-3) was
                             17

-------
waived because fosamine ammonium volatilization from soil does not appear to be
a major route of dissipation.

              (7)    Terrestrial field dissipation

       Fosamine ammonium rapidly dissipates  in the field.  Acceptable field
dissipation data indicate fosamine ammonium, at 24 Ibs a.i./A in 0-15 cm surface
soil, had a half-life of 1  day (Lexington, TN), 1  day (Newark, DE) and  5 days  at
Fayetteville,  NC.   Fosamine ammonium was detected (0.4 ppm) immediately
posttreatment in 15-30 cm soil samples at the Fayetteville,  NC site.   These
detections were  considered  to be  sample contamination because there was no
detection of fosamine ammonium at later sampling periods.

       Supplemental field dissipation data from small microplots  indicate fosamine
ammonium, at 11 kg/ha in 0-2 inch soil depth, had a calculated half-life of 1.1
weeks in a Delaware Keyport silt loam soil, 0.79 weeks in an Illinois Flanagan silt
loam,  0.55 weeks  in  a  Florida Leon Immokalee fine sandy loam soil.   The
degradate CPA  was detected at 26.7 percent  of recovered radioactivity in the
Delaware silt loam (6  weeks),  40 percent of the recovered radioactivity in the
Illinois silt loam (6 weeks), and  83 percent of the recovered radioactivity  in
Florida sandy loam (2  weeks).  Radiolabeled residues were detected (0.6 to 5.1
percent of applied radioactivity) to a depth of 15 inches soil samples after 3 to 12
months post  fosamine ammonium application.   The majority of radiolabeled
residues were not identified as fosamine ammonium and CPA (less than 1  percent
of recovered radioactivity at depths greater than 2 inches). Cumulative rainfall for
the studies was 64.95 inches (12 months) at the Delaware site, 26.85 inches at the
Illinois site (6 months), and 15.91 inches  at the  Florida site  (6 months).  Soil
samples were not taken deeper than 15 inches.

       Radiolabeled fosamine ammonium,  at 12 Ibs a.i/A applied to microplots
planted with  fescue, grass, red clover, and pin oak, was not detected  (less than
0.05 ppm) in underlaying  0-3 inch soil samples  between  1 to 12  months
posttreatment.  Radiolabeled residues in soil were CPA  (1.3 to 8.6 ppm at 1 month
to 0.5  to  1.1 ppm at 7 months)  and  unextractable residues (ratio  of CPA:
unextractable residues  (1:1)).  Radiolabeled fosamine ammonium was detected
(381-481 ppm immediately posttreatment to 0.05 ppm at 3 months posttreatment)
on plant foliage. The degradate  CPA  and carboxyphosphonic acid  also were
detected on plant foliage.
                              18

-------
       Field dissipation studies indicate that fosamine ammonium degrades rapidly
(t1/2 less than 5 days) in soil under typical use conditions.  Although fosamine
ammonium is a mobile compound, there is little evidence to indicate leaching is a
major route of dissipation.  In addition, supplemental studies indicate that CPA
dissipation does not appear to be dependent on leaching.  However, unidentified
residues were detected at a depth of 15 inches (MRID 40955701).

             (8)    Fish bioaccumulation

       Marginally  acceptable  accumulation in  fish data  indicate fosamine
ammonium  at   1  ppm did  not   bioaccumulate  in bluegill  sunfish  tissues.
Bioconcentration factors for fosamine ammonium could not be estimated because
of analytical limitations. Average concentrations of 14C-fosamine  ammonium were
0.334 mg/kg in fillet tissues,  0.337  mg/kg  in whole fish, and 0.348 mg/kg in
viscera. The Kow of fosamine ammonium also is low (less than 0.0012).  These
data indicate fosamine ammonium residues should not accumulate in fish tissues.
However,  a nine percent fish mortality was observed in the accumulation in fish
study.  Data requirements for Guideline 165-4 are satisfied.  (MRID 42587601).
              (9)    Droplet size spectrum and field drift studies

       Droplet size spectrum (Guideline 201-1) and field drift studies (Guideline
202-1) are needed to support ground spray and aerial spray application methods for
fosamine  ammonium.   These  data  requirements  have been  imposed on  the
registrant who has chosen  to satisfy them through participation in the industry
Spray Drift Task Force.  Spray Drift data from the Task Force are due June 30,
1995.  If the new data suggest substantially different drift potential  for the use
patterns  of fosamine  ammonium, the Agency will reassess its impact on the
associated environmental risks.

       b.      Environmental Fate Assessment

       Based on supplemental and acceptable environmental fate data, fosamine
ammonium dissipation is predominantly dependent on rapid, microbial-mediated
degradation (t1/2 0.5 to 11 days).  Fosamine ammonium  is also mobile (Kad less
than 1 and Rf greater than 0.98) in mineral soils.

       Degradates of fosamine ammonium are carbamoylphosphonic acid (CPA),
carboxylphosphonic acid (ING-3003), unidentified polar compounds and C02.
Supplemental soil column leaching studies indicate fosamine ammonium residues
are relatively immobile.  The mobility and persistence of individual degradates
(CPA, ING-3003, and unidentified polar degradates) are unknown at this time.
Field dissipation studies  confirm  laboratory data for  fosamine ammonium.
                             19

-------
Fosamine ammonium rapidly dissipated, with a half-life of less than 5 days from
the surface field soils. Leaching does not appear to be a major route of dissipation
for fosamine  ammonium and CPA  in field  studies.   However, unidentified,
radiolabeled polar residues were detected at a depth of 15 inches in confined field
dissipation studies.

       The environmental fate data indicate fosamine ammonium should be very
mobile in mineral soils.  However, fosamine ammonium should not pose a threat
to groundwater  or surface waters because it rapidly  degrades in  aerobic and
anaerobic environments. The mobility of CPA, ING-3003 and individual polar
degradates has not been adequately quantified at this time.

       Ground water.  Fosamine ammonium  (parent)  has a low probability to
impact ground-water quality. Although the chemical is highly soluble in water and
mobile in various soils, fosamine ammonium (parent) is not persistent in soil under
aerobic or anaerobic conditions.  The rapid degradation of fosamine ammonium
reduces the likelihood that the chemical will move through the aerobic soil layer
without any degradation. There are inadequate data to assess the environmental
fate   and  transport  of the  degradates   of  fosamine  ammonium,  namely
carbamoylphosphonic  acid (CPA) and carboxylphosphonic acid (ING-3003).
However, due  to the lack of toxicological concern for these compounds,  the
Agency is not requiring further definitive fate and transport data for them.
       Surface water.  Fosamine ammonium could move to surface water through
spray drift  and to a lesser extent in  surface water runoff.  There  is a low
probability that fosamine ammonium will be found in most runoff waters because
it degrades rapidly in aerobic and anaerobic environments  (t1/2 less than 4 days)
through microbial-mediated processes.  However, fosamine ammonium may  be
found in surface waters with low microbiological activities or long hydrological
residence times.   The Agency has no data on the  concentrations of  fosamine
ammonium in surface waters. The available data on major degradates of fosamine
ammonium are insufficient to assess their runoff potential  or persistence in surface
waters.  However,  available  data indicate that fosamine ammonium will not
significantly impact the quality of surface waters.

       Drinking Water. No MCLs or drinking water health advisories have been
established for fosamine ammonium or its degradates.  Consequently, the Agency
is  not recommending at this time  any  mandated monitoring of drinking water
derived from surface water sources for fosamine ammonium or its degradates.
                             20

2.     Ecological Effects

       The ecotoxicological data base is sufficient to characterize the toxicity of
fosamine ammonium to nontarget terrestrial and aquatic organisms when used on
noncropland for control of undesirable brush/herbaceous plant species.

       a.     Ecological Effects Data

              (1)    Terrestrial Data

                    (a)     Avian Acute Toxicity

       The minimum data required  to evaluate  the  acute toxicity of fosamine
ammonium to birds is an avian single-dose oral LD50 test with technical material
utilizing either a waterfowl or  upland game-bird species.  The minimum data
required to evaluate fosamine ammonium's subacute toxicity are two avian dietary
LC50 tests with technical material, utilizing a waterfowl and upland game-bird
species.  The minimum data required to evaluate chronic toxicity are two avian
reproduction studies with technical material, utilizing a waterfowl and an upland
game-bird species.

       Data from the avian single-dose studies indicate that technical fosamine
ammonium is practically nontoxic to avian species  on the  basis of acute oral
toxicity.  LD50s for a 99.4% TGAI fosamine ammonium in both the mallard duck
and the bobwhite quail are greater than 5000 mg/kg which was the highest dose
tested (MRIDs 00093715 and 00130225).


                    (b)     Avian Subacute Dietary Toxicity
       Data in support of avian subacute dietary toxicity indicate that technical
fosamine ammonium is practically nontoxic to avian species (mallard, bobwhite
quail).  The LC50s (> 10000 and 5620 ppm,  see Table 3) are estimated to be
greater than the highest dose tested  (MRIDs 00093716, 41891602, and 41891603).

                    (c)     Avian Reproduction/Chronic Effects

       Suggestive evidence  for  reproductive  effects to avian  species  was
demonstrated in a laboratory study sponsored  by the U.S.  Fish  and Wildlife
Service. This study examined the embryotoxic and teratogenic effects of various
solutions of the end-use product (EP: equivalent to 1.5 percent, 6.5 percent and
30 percent a.i.) on mallard and bobwhite quail eggs following a 10 second dipping.
An embryotoxic response was seen in eggs treated with the 6.5 percent and 30
percent EP solutions.  The solutions were more embryotoxic to the mallard than
to the bobwhite quail.  While this study is not a  guideline  study and is classified
as supplemental, it reflects a more representative exposure associated with direct
spray application to eggs.

       In  an avian reproduction study utilizing bobwhite quail, no reproductive
effects were noted at any of the dose levels tested (250, 1000, or 4000 ppm).  As
shown in  Table 8 below, the estimated environmental concentrations (EEC) of
fosamine ammonium on different avian and mammalian food items range from 18
ppm to 5760 ppm at the typical and maximum  application rates.   Because the
highest dose level tested, 4000 ppm, is below the maximum EEC of  5760 ppm on
short-grass, this study is classified as supplemental, but is  adequate to perform a
risk assessment on avian species (MRID 42948301).

       There is some indication of potential chronic avian reproduction effects in
another study utilizing mallard species fed 99.7% fosamine ammonium in the diet.
However,  this  study  deviated  from  the protocol and  was  not considered
scientifically sound.  While there was a statistically significant decrease in numbers
of eggs laid at the lowest concentration,  250 ppm (Williams test), no statistically
significant effects were  noted at the  highest dose level,  4000 ppm  (MRID
42948302).  These results were  considered ambiguous and were not used to assess
the risk to avian species.

       Given the ambiguous nature of the data from these studies, the Agency is
requiring a new mallard  duck reproduction  study for  confirmatory  purposes.
There appears to be no indication of reproductive effects in bobwhite quail based
on the concentrations  (up to  4000 ppm) tested,  therefore the  Agency is  not
requiring any additional data for the bobwhite quail.

                    (d)     Toxicity to Nontarget Mammals

       An LD50 value was derived from acceptable rat acute oral toxicity tests
submitted to EPA.  The rat LD50 of formulated fosamine ammonium (43 percent)
is  24400  mg/kg.  This value characterizes the  acute  toxicity  to mammals as
practically nontoxic (MRIDs 00075735,  00026835).

              (2)    Aquatic Data

                    (a)     Freshwater Fish Toxicity

       Two 96-hour LC50 fish toxicity tests utilizing the technical material are the
minimum data required to evaluate the acute toxicity of fosamine ammonium to
freshwater fish.  One test is  for warmwater fish, preferably bluegill sunfish, and
the other  is for coldwater fish, preferably rainbow trout.  The minimum  data
required to evaluate the acute  toxicity to estuarine/marine  species are  a fish  96-

shell deposition study or 48-hour EC50 on oyster embryolarvae, and a shrimp 96-

required to evaluate chronic toxicity are from a fish early life stage study.

       Data from fish acute toxicity studies indicate that fosamine ammonium is
practically nontoxic  to  coldwater  and  warmwater fish (MRIDs  41607103,
41607102 and 00129075).

                    (b)    Freshwater Invertebrate Toxicity

       The minimum data required to establish the acute toxicity  of fosamine
ammonium to freshwater invertebrates is a 48-hour LC50 test utilizing the technical
material. At a minimum chronic toxicity to aquatic invertebrates is evaluated by
an early life stage study.  These data indicate that technical fosamine ammonium
(99% ai) is practically nontoxic to freshwater invertebrates, such as  Daphnia (LC50
1524 ppm) (MRIDs 00143492 and 92086005).  No further data are required.

                    (c)    Estuarine/Marine Toxicity

       Fosamine  ammonium (41.5%  a.i.)  is practically nontoxic  to  estuarine
species as suggested by the results from the following studies (MRIDs 42715101,
42715103, and 42715102). No  further data are required.

Conclusions
practically
nontoxic
       For the current use patterns of fosamine ammonium, a fish early life stage
and  an invertebrate life cycle study could have  been triggered under  certain
conditions:
       (i) if actual or estimated environmental concentrations in water resulting
       from the use is less than 0.01 of any EC50 or LC50 value determined in
       required testing; and
       (ii) the pesticide is persistent in water (e.g.,  half-life in water greater than
       4 days).

       The Agency's assessment of fosamine ammonium for this RED document
indicates a half-life of less than 4  days in soil based on acceptable aerobic  and
anaerobic soil metabolism studies. Supplemental data show somewhat higher half-
life values (up to  1.2  weeks).  The half-life reported in the anaerobic  aquatic
metabolism study (t1/2 = 4) is a combined half-life in sediment and soil. Because
fosamine ammonium has a low binding affinity to sediment/soil, a similar half-life
in water is expected.  Based on these acceptable fate studies, showing a half-life
of less than 4 days in soil and a similar expected half-life in water, neither a fish-
early life stage study nor an invertebrate life cycle study is required for fosamine
ammonium.
              (3)    Non-Target Insects Data

       A  48-hour LD50 test utilizing the technical  material is the minimum
requirement to establish the acute toxicity of fosamine ammonium to nontarget
insects. The test organism is the honey bee (Apis mellifera).   In such a study
technical fosamine ammonium (95%  a.i.) was shown to be practically nontoxic to
the honey bee. The estimated LD50 is considered to be greater than 200 pig/bee
(MRID 41215802).

              (4)    Non-Target Plants Data

                    (a)     Terrestrial, Semi-Aquatic, Aquatic Plant Data

       The minimum data required to establish the phytotoxicity  of fosamine
ammonium are seed germination/seedling emergence testing for terrestrial plants
and aquatic plant testing.  For the aquatic plant testing, the following species were
required to be tested for fosamine ammonium:  Selenastrum capricornutum, Lemna
gibba, Skeletonema costatum, Anabaena flos-aquae, and a freshwater diatom.
Eight aquatic plant studies were submitted and found acceptable.

       The terrestrial plant studies which were submitted (MRID 42647601) are
classified as supplemental.  Data for four of the ten species tested  (corn, sugar
beet, pea and cucumber) were determined to be inadequate, because the seeds had
been pretreated with a fungicide  and/or insecticide.  These  studies need to  be
repeated using seeds that  have not been pretreated with a fungicide  and/or
insecticide.  Alternatively,  these studies may be accepted if the registrant can
successfully demonstrate that the  pretreatment pesticide was surface active and
non-systemic,  and not antagonistic to, or synergistic with fosamine ammonium.
These studies may be upgraded when acceptable Tier I seed germination, complete
Tier II  seedling emergence and complete Tier II  vegetative  vigor studies are
submitted (MRIDs 41215804, 42902901, 42902902, 42902904, 42902903, and
42587602).

       b.     Ecological Effects Risk Assessment

             (1)    Risk to Avian and Mammalian Species

       Characterizing risk  to avian  and mammalian species is a function  of
ecotoxicological hazard and environmental exposure.  The Agency characterizes
risk in part by calculating risk quotients, and compares them to levels of concern
(LOCs). A risk quotient is derived by dividing exposure (EEC) by an appropriate
toxicity endpoint (e.g. generally the LC50 or LD50 of the most sensitive species).
The  risk quotient is compared to the LOCs.   LOCs for birds and mammalian
species are: 0.5 for acute High Risk (HR); 0.2 for acute Restricted Use (RU); 0.1
for acute  Endangered Species (ES);  and 1.0 for chronic risk.  When the risk
quotient exceeds the LOG for a particular category, then risk to that category is
presumed  to exist.

       The Agency obtained estimates of expected environmental concentrations
(EECs) on various food items consumed by birds and mammalian species by using
the monograph  of Hoerger  and Kenaga  (1972).  These estimates were used  in
assessing risk, because actual field study residue data were lacking.  Hoerger and
Kenaga describe both "maximum" and  "typical" EECs.  Maximum EECs are those
values representing the most extreme, and, probably infrequent, residue scenarios.
Typical EECs are those values representing environmental  conditions which are
likely to occur.  For purposes of the  fosamine ammonium  risk assessment both
"typical"  and  "maximum"    EEC values are used.   Expected "typical" and
"maximum" EECs resulting from application of fosamine ammonium at the typical
and highest application rates are listed below.  Application  rates on the labels  of
currently registered products range from 6 Ib a.i./A to 24 Ib a.i./A.
                             27

              (2)
Avian Acute Oral and Chronic Risks
       The Agency's Guidelines for Avian Dietary LC50 Testing specify that a
study may demonstrate that the actual LC50 is greater than 5000 ppm in lieu of
demonstrating an actual LC50.  Both bobwhite quail and mallard studies included
tests up to the maximum 5000 ppm level and no indications of toxicity were noted
in either species. Therefore, the Agency has determined it is reasonable to assume
that the  levels of concern for acute effects  will not be exceeded if fosamine
ammonium is used as labeled.

       The avian reproductive effects via chronic ingestion of fosamine ammonium
are  not as clearly defined as the avian acute oral effects.  While some data suggest
potential sensitivity to mallards, no effects were observed in bobwhite quail at the
highest dose  tested  (4000  ppm).   The data which  are  indicative of avian
reproductive effects,  however, are either ambiguous or do not meet guideline
requirements.

       Additional non-guideline data were  provided by the U.S. Fish and Wildlife
Service.  These studies indicated that 6.5 percent and 30 percent end-use product
solutions  containing  fosamine  ammonium  produced a  statistically  greater
embryotoxic response in mallard ducks than bobwhite quail eggs.

       Because of the ambiguity associated with the mallard duck reproduction
study, the Agency is relying on the bobwhite guideline reproduction study and the
U.S.  Fish and Wildlife Service data for the risk  assessment.  A conservative
quantitative estimation of risk using the maximum application rate of 24  Ib a.i./A
was performed for  this risk assessment using only bobwhite quail reproductive
data.  The risk quotient for chronic  effects using the bobwhite quail data (5760
                             28

-------
ppm/4000 ppm) is  1.4 which exceeds the Agency's level of concern for avian
chronic risk (LOG = 1).  Therefore based on a conservative estimation of risk, the
use of fosamine ammonium may present a potential for chronic risk to avian
species.

       However, in order to determine whether there are  actual reproductive
effects associated with chronic exposure to fosamine ammonium, the Agency is
requiring the registrant to conduct a new confirmatory mallard duck reproduction
study.  The Agency has determined that the bobwhite quail study is adequate for
purposes of this risk assessment.  In addition, the registrant has provided to the
Agency some initial risk mitigation  measures which may help reduce the avian
exposure to  fosamine  ammonium and thereby reduce the potential reproductive
risk. The risk mitigation measures are discussed in Sections IV and V below.

             (3)    Mammalian Acute Oral and Chronic Risks

       Using the rat  as a small mammal surrogate, fosamine  ammonium  is
expected to be practically non-toxic to small mammalian species.  The rat LD50 of
formulated fosamine ammonium (43%) is 24,400 mg/kg. Acute oral and subacute
dietary  risks to  non-endangered and endangered non-target mammals are not
expected to result from present label uses of fosamine ammonium.

       The results of an acceptable developmental toxicity study, in which sexually
mature rats were gavaged for an eleven day period with fosamine ammonium  at
levels up to 3000 mg/kg/day, showed no mortality  (3000 mg/kg/day equates to
about 30000 ppm).  No mortality was seen at the highest dose tested, 20000 ppm,
in an acceptable 90-day neurotoxicity study.  Given that the highest exposure case
EEC for fosamine ammonium is 5760 ppm, and  comparing this value to actual
mammalian data showing no acute/longer term effects at levels up to 30000 ppm,
there would  be no expected acute or  chronic mammalian effects to occur.

             (4)    Risks to Aquatic Animals

       Exposure to nontarget aquatic organisms can result from spray drift and
runoff from  treated areas. Characterizing risk to aquatic species is a function of
ecotoxicological hazard and environmental exposure.  It is performed in a manner
similar to that for birds and small mammals.  The exception is that the EECs are
calculated differently.  The Agency calculates risk quotients (EEC/LC50 or LD50
of the  most sensitive  species),  and then compares these to levels of concern
(LOCs). LOCs  for aquatic species are:  0.5 for acute High Risk (HR); 0.1 for
acute Restricted  Use (RU); 0.05 for acute Endangered  Species (ES); and 1.0 for
chronic  risk. When the risk quotient exceeds the LOG for a particular category,
then risk to that category is presumed to exist.
                             29

-------
              Estimated Environmental Concentrations (EECs) were calculated using the
       Agency's Hazard Evaluation  Division's  Standard Evaluation Procedure for
       Ecological Risk Assessment (EPA-540/9-85-001).  These estimates were used in
       assessing risk, because actual field study residue data were lacking.  The Agency
       generally employs the highest application rate permitted on the label and calculates
       the EEC resulting from direct application, from spray drift, and from runoff of the
       pesticide into a 6-foot deep 1-acre pond, and the EEC resulting from runoff of the
       pesticide into a 6-inch deep 1-acre pond. For purposes of this risk assessment, the
       typical (12 Ib a.i./A) and highest (24 Ib a.i./A) application rates were employed.

              The EECs resulting from direct  application,  spray  drift, and runoff of
       fosamine ammonium applied at 12 and 24 Ib a.i./A application rates into 6 inch
       and 6 foot deep one acre ponds are listed in  4 below. This table also provides a
       comparison of acute risk quotients to the Agency's levels of concern (LOCs). The
       LC50 for rainbow trout (96-hr LC50 of 377), the most sensitive freshwater aquatic
       organism tested, was used in risk quotient calculations.

              The acute risk quotients do not exceed any level of concern.  Therefore, the
       Agency concludes that acute effects to freshwater fish and aquatic invertebrates are
       not expected as a result of the normal use of fosamine ammonium.

              In the absence of an actual LC50 or EC50, the Agency did not estimate an
       acute risk quotient for  estuarine species. However, the highest dose levels tested
       in each of the three estuarine species tested resulted in  no mortalities (sheepshead
       minnow 96-hr LC50 > 128 ppm; mysid shrimp 96-hr LC50 > 136 ppm; and eastern
       oyster 96-hr EC50  > 122 ppm). Therefore, the Agency assumes that  acute hazards
                                     30

-------
      to estuarine species are not expected as a result of the use of fosamine ammonium
      as labeled.
             Additional information which supports this conclusion are: (i) there is only
      one seasonal application of fosamine ammonium; (ii) acute  toxicity values are
      greater than 1 ppm, (iii) EECs in water are less than 0.01 of individual acute
      toxicity values; and (iv) environmental fate data (anaerobic aquatic metabolism)
      indicate a half life of 4 days under certain conditions.  The Agency also believes
      that it is reasonable to assume that there are no chronic risks to aquatic organisms.

                    (5)    Risks to Aquatic Plants

             Exposure  to nontarget  aquatic plants can result from spray drift from
      treated  areas,  surface runoff,  or wind  blown  soil  particles.    Estimated
      Environmental Concentrations (EECs) were calculated using the Agency's Hazard
      Evaluation  Division  Standard  Evaluation Procedure  for  Ecological  Risk
      Assessment (see  under Risks to Aquatic Organisms).  The Agency's LOG for
      aquatic plants is  1.  There are  no separate LOCs for  restricted use, endangered
      species, or chronic risks.  If the EEC _>_ EC25,  the Agency presumes a high risk
      and endangered plants may be  affected.  The risk quotient is derived  using the
      most conservative EC25 value for aquatic plants,  greater than 15 mg/1 (the highest
      level tested for Skeletonema costatum).

             None of the acute risk quotients exceed the LOC.  Therefore, the Agency
      concludes that no acute effects to aquatic plants are expected as a result of the use
      of the registered uses of fosamine ammonium.  A chronic  risk assessment to
      aquatic plants cannot be performed because data are  not available. However, the
      registrant is not supporting any aquatic sites.  Data in support of chronic risks to
      aquatic plants will be required if, in the future, the registrant wishes to register
      such sites.
                                    31

-------
                           (6)    Risk to Terrestrial Plants

                    A terrestrial nontarget plant risk assessment cannot be conducted until all
              Tier I and II data requirements have been fulfilled. Data are outstanding for corn,
              sugar beet, pea and cucumber. Because results of the most sensitive terrestrial
              plant species tested are needed in order to conduct an acute risk assessment, a risk
              assessment cannot be performed.   Any movement of this herbicide from the
              treatment site via spray drift, surface runoff, or wind blown soil particles has the
              potential to adversely affect nontarget and endangered/threatened plants.  Direct
              applications to rights-of-way are a special concern, because of the large numbers
              of endangered plants growing in rights-of-way areas.

                    Applications of fosamine ammonium  at the registered  rates may pose a
              significant risk to endangered plant species inhabiting treated rights-of-way.  EPA
              has been working with the U.S. Fish and Wildlife Service and other federal and
              state agencies to develop a program  to avoid jeopardizing the continued existence
              of listed endangered species from the use of pesticides. The Endangered Species
              Protection Program is expected to become final in 1995.  Limitations on the use
              of fosamine ammonium may be required to protect endangered and threatened
              species,  but these limitations have not yet been defined, and  they  may be
              formulation-specific.  The Agency anticipates that consultation with the U.S. Fish
              and Wildlife Service will be  conducted in  accordance  with the species-based
              priority approach described in the Program. After completion of the consultation,
              registrants will be informed if any required  label  modifications are necessary.
              Such modifications  would  most likely  consist of the generic label statement
              referring pesticide users to use limitations contained in county Bulletins.

IV.    RISK MANAGEMENT AND REREGISTRATION DECISION

       A.     Determination of Eligibility

              Section 4(g)(2)(A) of FIFRA calls for the Agency to determine, after submission
       of relevant data concerning an active ingredient, whether products containing the active
       ingredients are  eligible for reregistration.  The Agency has previously identified and
       required the submission of the generic (i.e. active ingredient specific) data required to
       support reregistration of products containing fosamine ammonium as the  active ingredient.
       The Agency has  completed its review of these generic data, and has determined that the
       data are sufficient to support reregistration of products containing fosamine ammonium
       for certain sites as specified in this document.   The  registrant has voluntarily requested
       cancellation of the aquatic sites as discussed previously. Appendix B identifies the generic
       data requirements that  the Agency reviewed as part of its determination of reregistration
       eligibility of fosamine ammonium,  and lists the submitted studies that the Agency found
       acceptable.
                                           32

-------
       The data identified in Appendix B for fosamine ammonium were sufficient to allow
the Agency to assess its registered uses, except for aquatic  sites.  The Agency has
determined that fosamine ammonium can be used for registered sites, except the aquatic
sites,  as specified in this document, without resulting in unreasonable adverse effects to
humans or the environment.  The Agency is requiring risk mitigation measures for non-
target animal species. The reregistration requirements of fosamine ammonium products
are addressed in this Section and in Section V below.

       The Agency made its reregistration eligibility determination based upon the target
database required for reregistration,  the  current guidelines for  conducting  acceptable
studies to generate such data, the registrant's request for voluntary  cancellation of aquatic
sites and the data identified in Appendix B.  The Agency has found that certain uses of
fosamine ammonium, as  discussed in this document, are eligible for reregistration, under
the conditions specified  herein. However, it should be understood that the Agency may
take appropriate regulatory action, and/or require the submission of additional data to
support the reregistration of products containing fosamine ammonium, if new information
comes to the Agency's attention or if the data requirements for reregistration (or  the
guidelines for generating such data) change.

       1.     Eligibility Decision

              Based on  the reviews of the generic data for the active ingredient, fosamine
       ammonium,  the Agency has sufficient information on the health effects of fosamine
       ammonium and on its potential for causing adverse effects in fish and wildlife and
       the environment.   The Agency has determined that fosamine ammonium products,
       labeled  and used on sites as specified in this Reregistration Eligibility Decision
       document, will not pose unreasonable risks of adverse  effects to humans or  the
       environment, and are therefore eligible for reregistration.

       2.     Eligible and Ineligible Uses

              The Agency has determined that all currently registered uses of fosamine
       ammonium,  except for aquatic sites, as described in this document, are eligible  for
       reregistration.   The registrant has voluntarily requested cancellation  of those
       aquatic sites.  The Agency is not including those sites in  its  eligibility decision,
       because of the inadequate environmental data for those sites and the  impending
       deletion of those uses from all current registrations.

B.     Regulatory Position

       The following is a summary of the regulatory positions and rationales for fosamine
ammonium.  Where  labeling revisions are imposed,  specific  language is set forth in
Section V of this document.
                                     33

-------
1.     Tolerance Reassessment

       Tolerances are not  currently established  for  the  herbicide  fosamine
ammonium since there is no registered food or feed use.

2.     Labeling Rationale/Risk Mitigation Measures

       a.     Personal Protection Equipment (PPE) Requirements

       The current registered uses of fosamine ammonium do not include uses
associated with the production  of an agricultural plant on/in any farm, forest,
nursery, or greenhouse.  Sites on which this herbicide/plant growth regulator is
used are limited to utility rights-of-way, outdoor industrial areas, campgrounds,
storage areas and noncropland. These  uses and the single registered product do not
fall under the scope  of PR  Notice 93-7, "Labeling Revisions Required by the
Worker Protection Standard (WPS),"  and PR Notice  93-11,  "Supplemental
Guidance for PR Notice 93-7".  The Agency's labeling regulations for worker
protection statements (40 CFR 156, subpart K) are not applicable to fosamine end-
use products at this time.

       For each end-use product, PPE requirements for pesticide handlers will be
set in one of two ways:

       1.     If EPA has no special concerns about the  acute or other adverse
             effects of an active  ingredient, the PPE for pesticide handlers will
             be established based on the acute toxicity of the end-use product.
             For occupational-use products, PPE will be established using the
             process  described  in PR  Notice 93-7  or more  recent  EPA
             guidelines.

       2.     If EPA has special concerns about an active ingredient due to very
             high acute toxicity or to certain  other adverse effects, such as
             allergic effects,  cancer,  developmental toxicity, or  reproductive
             effects, the following conditions apply:

                    o In the RED for that active ingredient, EPA may establish
                    minimum or  "baseline" handler PPE  requirements that
                    pertain to  all  or  most  occupational  end-use  products
                    containing that active ingredient.

                    o  These  minimum PPE requirements must be compared
                    with the PPE that would be designated on the basis of the
                    acute toxicity of each end-use product.
                             34

-------
                    o  The more stringent choice for each type of PPE  (i.e.,
                    bodywear, hand protection, footwear, eyewear, etc.)  must
                    be placed on the label of the end-use product.

       There are no special toxicological concerns about fosamine ammonium that
       warrant the establishment of baseline or minimum active-ingredient based
       PPE for handlers  (mixer/loader/applicators).    Therefore, the PPE for
       pesticide handlers will be established based on the acute toxicity of the end-
       use product.

              The Agency is establishing the following entry restrictions for the
       occupational uses of fosamine ammonium end-use products:

              For liquid applications:
       "Do not enter or allow others to enter the treated area until
       sprays have dried."

       Other Labeling Requirements

              The Agency is requiring labeling statements concerning application
       restrictions and user safety recommendations to be located on all end-use
       products containing fosamine ammonium that are intended primarily for
       occupational use.   See Chapter V for the  actual statements.

       b.     Spray-Drift Label Advisory

              In order to inform the user of best management practices that would
       minimize spray drift from the target site, the Agency is currently preparing
       spray  drift statements.   This future  labelling may be required  for all
       fosamine products  that may be applied aerially.

       c.     Avian Risk Mitigation

       The Agency has determined that there is a potential for adverse effects on
avian reproduction with the use of fosamine ammonium. The data indicative of
such effects are not conclusive as discussed earlier (Section III).  Briefly, the  U.S.
Fish and Wildlife data suggest that reproduction in avian species may be adversely
affected when eggs are directly exposed to sprays of the end-use product (EP). By
way of contrast,  the data  from the bobwhite quail reproduction study shows no
effects at any dose levels.  The  Agency, therefore, thought it prudent to regulate
fosamine ammonium based on the weight of evidence supporting the reregistration
of  fosamine,  the low  toxicity  profile of  the herbicide and  the following
considerations.
                              35

-------
       Information provided  by Agency  use  experts  suggests  that  fosamine
ammonium is not typically applied at the permitted maximum application rate of
24 Ib a.i./A.  Rather,  users and the registrant suggest that as much as 80 percent
of the use of fosamine ammonium is at the rate of 12 Ib a.i. to 16 Ib a.i.  per acre.
Based on these more typical use rates, the estimated EECs for avian species would
be approximately 33 percent to 50 percent  lower than for the 24 Ib a.i. rate.  In
addition, less than one percent of the sites are treated with fosamine ammonium,
and application is limited to once per  year.  Furthermore, the sites treated are
narrow strips of land, rather than vast acreages of cropland.  These factors further
decrease the potential for exposure to nesting birds.

       The  registrant has  voluntarily submitted label  amendments  to  allow
applications during the period after spring growth has hardened to the development
of fall coloration on deciduous species, and to restructure maximum rates of
application.  These label amendments reduce the maximum application rate to 16
Ib a.i./A for low shrubs/brush (floor work), which constitute 80 percent of the use
of the herbicide.  Applications to a maximum of 24 Ib a.i./A are proposed only for
tall dense wood species with very heavy foliage (side trim work). Prior to this
modification, all applications were permitted up to the 24 Ib a.i./A.

       Additionally, submission of a new mallard duck reproduction study should
resolve any question of the potential for fosamine  ammonium to cause reproductive
effects in this avian species.  The Agency may require further risk mitigation
measures depending on the results of the required study.

3.     Endangered Species Statement

       The Agency has concerns about the exposure of threatened and endangered
avian species to fosamine ammonium as discussed above in the Section IIIC.

       Currently, the Agency is developing a program ("The Endangered Species
Protection Program") to  identify  all  pesticides whose  use may cause adverse
impacts on endangered  and threatened species and to  implement mitigation
measures that will eliminate the  adverse  impacts.  The program would require use
modifications  or  a generic  product label statement, requiring users to consult
county-specific bulletins. These bulletins would provide information about specific
use restrictions to protect  endangered and threatened species in the county.
Consultations with the Fish and Wildlife Service will be necessary to assess risks
to newly listed species or from proposed new uses.

       The  Agency plans  to publish  a description  of the Endangered Species
Program in the Federal Register in 1995 and have  enforceable county-specific
bulletins available. Because the Agency is taking  this  approach for protecting
endangered and threatened species, it is not imposing label modifications at this
                              36

-------
             time through the RED.  Rather, any requirements for product use modifications
             will occur in the future under the Endangered Species Protection Program.

V.     ACTIONS REQUIRED BY REGISTRANTS

       This section specifies the data requirements and responses necessary for the reregistration
of both manufacturing-use and end-use products.

       A.    Manufacturing-Use Products

             1.     Additional Generic Data Requirements

             While there is currently no registered manufacturing-use product, the generic data
             base supporting the reregistration of fosamine ammonium for the above eligible
             uses has been reviewed and determined to be substantially complete except for the
             following confirmatory data requirements:

       •     Guideline 62-2: Certification of limits.  The registrant must provide information
             to certify that the limits are within the standards required by  40 CFR §158.120.
             Guideline 71-4b: Avian reproduction (mallards). Data are required to confirm
             that the chronic avian reproductive risk does not exceed the Level of Concern at
             the Estimated Environmental Concentration.

             Guideline 84-2a:  An in-vivo cytogenetics assay on spermatogonia/spermatocytes
             to satisfy Guideline 84-2a requirements for toxicology mutagenicity.

             Guideline 201-1,  Guideline 202-1:  Droplet size spectrum, and field drift data are
             needed to evaluate  off-target movement of spray applied fosamine ammonium.
             These data  requirements are being fulfilled by the registrant through their
             participation in  the Spray Drift  Task Force.   These data are scheduled  for
             submission by June 30, 1995.

             Guidelines 231, 232:  Method validation data for worker exposure study,  MRID
             42598101.

             Guidelines 122-1  and 123-1:  Terrestrial plant testing data requirements. Four of
             the ten terrestrial plant testing studies for corn, sugarbeet,  pea, and cucumber,
             need  to be repeated.  Alternatively, the registrant can provide documentation to
             demonstrate that the compounds used for pretreatment of seeds  do not interfere
             with the fosamine ammonium results in these studies.  The other studies may be
             upgraded when acceptable Tier I seed germination, complete Tier II emergence
             and complete Tier II vegetative vigor studies are submitted.
                                          37

-------
Guidelines  164-2  and 162-4.  Aerobic  aquatic metabolism  and aquatic field
dissipation data would be required to support future use patterns of an aquatic site.
Assuming that the aquatic sites will be deleted from the current registration, the
Agency does not expect to receive these data.  In the future, if the registrant wishes
to register any aquatic uses,  these and all data in support of those sites must be
resubmitted.

2.     Labeling Requirements for Manufacturing-Use Products

              Effluent Discharge Labeling Statements

       While  there is no currently registered manufacturing-use  product, these
requirements are appropriate for future registrations of fosamine ammonium.

       All manufacturing-use or end-use products  that may be contained in an
effluent discharged to the waters of the United States or municipal sewer systems
must bear the  following revised effluent discharge labeling statement.

Within Environmental Hazards section of the Precautionary Statement of the label:

"Do not  discharge effluent containing this product  into lakes, streams, ponds,
estuaries, oceans or other waters unless in accordance with the requirements of a
National Pollutant Discharge  Elimination System (NPDES) permit  and the
permitting authority has been notified in writing  prior  to  discharge. Do not
discharge effluent containing this product to sewer  systems without previously
notifying the local sewage treatment plant authority. For guidance contact your
State Water Board or Regional Office of the EPA."

       All affected products distributed or sold by registrants and  distributors
(supplemental registrants)  must bear the above labeling  by October 1,  1995. All
products distributed or sold  by persons other than  registrants or supplemental
registrants after October  1,  1997 must bear the correct  labeling. Refer to PR
Notice 93-10 or 40 CFR 152.46(a)(l) for  additional  information.
                              38

-------
B.     End-Use Products

       1.      Additional Product-Specific Data Requirements

              Section 4(g)(2)(B) of FIFRA calls for the Agency to obtain any needed
       product-specific data regarding the pesticide after a determination of eligibility has
       been made. The product specific data requirements are listed in Appendix G, the
       Product Specific Data Call-in Notice.

              Registrants must review previous data submissions to ensure that they meet
       current EPA acceptance criteria (Appendix F; Attachment E) and if not, commit
       to conduct new studies.  If a registrant believes that previously submitted data meet
       current testing standards, then study MRID numbers should be cited according to
       the instructions in the Requirement Status and Registrants Response Form provided
       for each product.

       2.      Labeling Requirements for End-Use Products

              The labels and labeling of all products must comply with EPA's current
       regulations and requirements as specified in 40 CFR §156.10 and other applicable
       notices.

       (a) Within Environmental Hazards section of the Precautionary Statement of the
       label:

              "Do not apply directly to water, or to areas where surface water is present
              or to intertidal areas below the  mean high water mark. Do not contaminate
              water when disposing of equipment washwaters or rinsate."

       (b) To reduce environmental loading and potential exposure to non-target species,
       the product label must include language to limit use as outlined below:

              (i) the end-use product can be applied only once annually during the period
              after spring growth has hardened to the development of fall coloration in
              deciduous species, and
              (ii) the maximum application rate for low shrubs/brush is 16 Ib  a.i./A, and
              for tall  dense woody species with very heavy foliage can be 24 Ib a.i./A.

       (c) The end-use product labels cannot  include directions for applications to aquatic
       sites.   The current, sole registrant  has  submitted an application  for  amended
       registration to delete  these uses from its product registration. Future submissions
       of appropriate data to support registration for these uses will be considered by the
       Agency.
                                    39

-------
(d)  The Agency is requiring the following labelling statements to be located on all
end-use products containing fosamine ammonium:

       Application Restrictions:

              "Do not apply this product in a way that will contact workers or
              other persons, either  directly or through drift.   Only protected
              handlers may be in the area during applications."

       Entry restrictions

              The Agency is establishing the following entry restrictions for the
       occupational uses of fosamine ammonium end-use products:

              For liquid applications:
       "Do not enter or allow others to enter the treated area until
       sprays have dried."

       Other Labelling Requirements

       User Safety Recommendations:

              •      "Users should wash hands before eating, drinking,
                     chewing gum, using tobacco, or using the toilet."

              •      "Users  should  remove  clothing   immediately if
                     pesticide gets inside.  Then wash thoroughly and put
                     on  clean clothing."

              •      "Users  should  remove clothing immediately after
                     handling this product. If gloves are worn, wash the
                     outside of gloves before removing.   As  soon as
                     possible, wash thoroughly and change  into clean
                     clothing."

              These  statements  must  be  included on the labels, as they are
       appropriate,  after PPE requirements are set by the Agency.
                             40

-------
C.     Spray Drift Label Advisory

       In order to inform the user  of best management practices that would minimize
spray drift from the target site, the Agency is currently preparing spray drift labelling
statements.  This future labelling may be required for all fosamine ammonium products
that may be applied aerially.

D.     Existing Stocks

       Registrants may generally distribute and sell products bearing old labels/labeling
for 26 months from the date of the issuance of this  Reregistration Eligibility Decision
(RED). Persons other than the registrant may generally  distribute or sell such products for
50 months from the date  of the issuance  of this RED.  However,  existing stocks time
frames will be established  case-by-case, depending on the number of products involved,
the number of label changes, and other factors. Refer to "Existing Stocks of Pesticide
Products; Statement of Policy"; Federal Register, Volume 56, No. 123, June 26, 1991.

       The  Agency has determined that  registrants  may distribute and sell fosamine
ammonium products bearing old labels/labeling for 26 months from the date of issuance
of this RED. Persons other than the registrant may distribute  or sell such products for 50
months from the date of the issuance of this RED.  Registrants and persons other than
registrants remain obligated  to meet pre-existing Agency  imposed label  changes and
existing stocks requirements applicable to products they sell or distribute.

                               GUIDE TO APPENDIX B
Appendix B contains listings of data requirements which support the reregistration for active
ingredients within the case 2355 covered by this Reregistration Eligibility Decision Document.
It contains generic data requirements that apply to 2355 in all products, including data
requirements for which a "typical formulation"  is the test substance.

       The data table is organized in the following format:

       1.  Data Requirement (Column 1).  The data requirements are listed in the order in
which they appear in 40 CFR Part 158. the reference numbers accompanying each test refer
to the test protocols set in the Pesticide Assessment Guidelines, which are available from the
National Technical Information Service,  5285 Port Royal Road, Springfield, VA 22161 (703)
487-4650.

       2.  Use Pattern (Column 2).  This column indicates the use patterns for which the data
requirements apply.  The following letter designations are used for the given use patterns:

                           A      Terrestrial food
                           B      Terrestrial feed
                           C      Terrestrial non-food
                           D      Aquatic food
                           E      Aquatic non-food outdoor

                               GUIDE TO APPENDIX C

1.      CONTENTS OF BIBLIOGRAPHY.  This bibliography contains citations of all studies
       considered relevant by EPA in arriving at the positions and conclusions stated
       elsewhere in the Reregistration Eligibility Document. 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,
       are 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 also
       attempted to  unite basic documents and commentaries upon them, treating them as a
       single study.

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

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

       b.     Document date.  The date of the study is taken directly from the document.
             When the date is followed by a question mark, the bibliographer has deduced
             the date from the evidence contained in the document.  When the date appears


                                           63

-------
       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 the Agency bibliographers to
       create or enhance a document title.  Any such editorial insertions are contained
       between square brackets.

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

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

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

       (3)    Submitter.  The third  element is the submitter.  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," which stands 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.

                                            July 29, 1986

                                                                             OFFICE OF

            NOTICE TO PRODUCERS, FORMULATORS, DISTRIBUTORS
                                AND REGISTRANTS

Attention:    Persons responsible for Federal registration of pesticides.

Subject:             Standard format for data submitted under the Federal Insecticide,
                    Fungicide, and Rodenticide Act (FIFRA) and certain provisions of the
                    Federal Food, Drug,  and Cosmetic Act (FFDCA).

I.  Purpose

       To require data to be submitted to the Environmental Protection Agency (EPA) in a
standard format. This Notice also provides  additional guidance about, and illustrations of, the
required formats.

II. Applicability

       This PR Notice applies to all data that are submitted to EPA to satisfy data
requirements for granting or maintaining pesticide registrations, experimental use permits,
tolerances, and related approvals under certain provisions of FIFRA and FFDCA. These data
are defined in FIFRA §10(d)(l). This Notice does not  apply to commercial, financial, or
production  information, which are, and must continue  to oe, submitted differently under
separate cover.

III. Effective Date

       This notice is effective on November 1, 1986. Data formatted according to this notice
may be submitted prior to the effective date.  As of the  effective date, submitted data packages
that do not conform to these requirements may be returned to the submitter for necessary
revision.

IV. Background

       On September 26,  1984, EPA published proposed regulations in the Federal Register
(49 FR 37956) which include Requirements for Data Submission (40 CFR §158.32), and
Procedures for Claims of Confidentiality of Data (40 CFR §158.33). These regulations
specify the format for data submitted to EPA under Section  3 of FIFRA and Sections 408 and
4139 of FFDCA, and procedures which must be followed to make and substantiate claims of
confidentiality. No entitlements to data confidentiality are changed, either by the proposed
regulation or by this notice.

       OPP is making these requirements mandatory through this Notice  to gain resource-
saving benefits from their  use before the entire proposed regulation becomes final. Adequate
lead time is being provided for submitters to comply with the new requirements.
                                         81

-------
V.     Relationship of this Notice to Other OPP Policy and Guidance

       While this Notice contains requirements for organizing and formatting submittals of
supporting data,  it does not address the substance of test reports themselves. "Data reporting"
guidance is now  under development in OPP,  and will specify how the study objectives,
protocol, observations, findings, and conclusions are organized and presented within the study
report. The data reporting guidance will be compatible with submittal format requirements
described in this Notice.

       OPP has  also promulgated a policy (PR Notice 86-4 dated April 15, 1986) that
provides for early screening of certain applications for registration under FIFRA §3.  The
objective of the screen is to avoid the additional costs and prolonged delays associated with
handling significantly incomplete application packages.  As of the effective date of this Notice,
the screen will include in its criteria for acceptance of application packages the data formatting
requirements described herein.

       OPP has  also established a public docket which imposes deadlines for inserting into the
docket documents submitted in connection with Special Reviews and Registration Standards
(see 40 CFR §154.15 and §155.32). To meet these deadlines, OPP is requiring an additional
copy of any data submitted to the docket. Please refer to Page 10 for more information about
this requirement.

       For several years, OPP has required that each application for registration or other
action  include a  list of all applicable data requirements and an indication of how each is
satisfied—the statement of the  method of support for the application.  Typically, many
requirements are satisfied by reference to data previously submitted—either by the applicant or
by another party. That requirement is not altered by this notice, which applies only to data
submitted with an application.

VI.    Format Requirements

       A more detailed discussion of these format requirements follows the index on the next
page, and samples of some of the requirements are attached.  Except for the language  of the
two alternative forms of the Statement of Data Confidentiality Claims (shown in Attachment 3)
which  cannot be altered, these samples are illustrative. As long as the required information is
included and clearly identifiable, the form of the samples may be altered to reflect the
submitter's preference.

E.     Reference to Previously Submitted Data	   9

F.     Physical Format Requirements & Number of Copies	   9

G.     Special Requirements for Submitting Data to the Docket  	10
A.     Organization of Submittal Package

       A "submittal package" consists of all studies submitted at the same time for review in
support of a single regulatory action, along with a transmittal document and other related
administrative material (e.g. the method of support statement, EPA Forms 8570-1, 8570-4,
8570-20, etc.) as appropriate.

       Data submitters must organize each submittal package as described in this Notice.  The
transmittal and any other administrative material must be grouped together in the first physical
volume.  Each study included in the submittal package must then be bound separately.

       Submitters  sometimes provide additional materials that are intended to clarify,
emphasize, or otherwise comment to help Product Managers and reviewers better understand
the submittal.

       -  If such materials relate to one study, they should be included as an appendix to that
       study.

       - If such materials relate to more than one study (as for example a summary of all
       studies in a discipline) or to the submittal in general, they must be included in the
       submittal package as a separate study (with title page and statement of confidentiality
       claims).

B.     Transmittal Document

       The first item in each submittal package must be a transmittal document. This
document identifies the submitter or all joint submitters; the regulatory action in support of
which the package is being submitted--i.e., a registration application, petition, experimental
use permit (EUPj, §3(c)(2j(B)  data call-in, §6(aj(2) submittal,  or a special review; the
transmittal date;  and a list of all individual studies included in the package in the order of their
appearance,  showing (usually by Guideline reference number) the data requirement(s)
addressed by each one.  The EPA-assigned number for the regulatory action  (e.g. the
registration, EUP, or tolerance petition number) should be included in the transmittal
document as well,  if it is known to the submitter.  See Attachment 1 for an example  of an
acceptable transmittal document.

       The list of included studies in the transmittal of a data submittal package supporting a
registration application should  be subdivided by discipline, reflecting the order  in which data
requirements appear in 40 CFR 158.

       The list of included studies in the transmittal of a data submittal package supporting a
petition for tolerance or an application for an EUP should be subdivided into sections A, B,
C,.... of the petition or application, as defined in 40 CFR  180.7 and 158.125, (petitions) or
Pesticide Assessment Guidelines, Subdivision I (EUPs) as appropriate.

       When a submittal package supports a tolerance petition  and an application for a
registration or an EUP, list the petition studies first, then the balance or the studies.  Within
these two groups of studies follow the instructions above.


                                           83

-------
C.     Individual Studies

       A study is the report of a single scientific investigation, including all supporting
analyses required for logical completeness. A study should be identifiable and distinguishable
by a conventional bibliographic citation including author, date, and title.  Studies generally
correspond in scope to a single Guideline requirement for supporting data, with some
exceptions discussed in section C.I.  Each study included in a submittal package must be
bound as a separate entity.  (See comments on binding studies on page 9.)

       Each study must be consecutively paginated, beginning from the title page as page 1.
The total number of pages in the com-plete study must be shown on the study title page.  In
addition (to ensure that inadvertently separated pages can be reassociated with the proper study
during handling or review) use either of the following:

       - Include the total number of pages in the complete study on  each page (i.e.,  1 of 250,
       2 of 250, ...250 of 250).

       - Include a company name or mark and study number on each page of the study, e g ,
       Company Name-1986-23.  Never reuse a study number for marking the pages of
       subsequent studies.
       When a single study is  extremely long, binding it in mul-tiple volumes is permissible
so long as the entire  study is pag-inated in a single series, and each volume is plainly identified
by the study title and its position in the multi-volume sequence.

C.I    Special Considerations  for Identifying Studies

       Some studies raise special problems in study identification, because they address
Guidelines of broader than normal scope or for  other reasons.

       a. Safety Studies. Several Guidelines require testing for safety in more than one
species. In these cases  each species tested should be reported as a separate study, and bound
separately.

       Extensive supplemental reports  of pathology reviews, feed analyses, historical control
data, and the like are often associated with safety studies.  Whenever possible these should be
submitted with primary reports of the study, and bound with the primary study as appendices.
When such supplemental reports are  submitted independently of the  primary report, take care
to fully identify the primary report to which they pertain.

       Batteries of acute toxicity tests,  performed on the same end use product and covered by
a single title page, may be bound together and reported as a single study.

       b. Product Chemistry Studies.  All product chemistry data within a submittal package
submitted in support of an end-use product produced from registered manufacturing-use
products should be bound as a single study under a single title page.

       Product chemistry data submitted in support of a technical product, other
manufacturing-use product, an experimental use permit, an import tolerance petition, or  an
end-use product produced from unregistered source ingredients, should be bound as a single
study for each Guideline series (61, 62, and 63) for conventional pesticides, or for the
equivalent subject range for biorational pesticides.  The  first of the three studies in a complete
product chemistry submittal for a biochemical pesticide would  cover Guidelines 151-10,
151-11, and 151-12;  the second would  cover Guidelines 151-13, 151-15,  and  151-16; the third
would cover Guideline 151-17. The first study for a microbial  pesticide would cover
Guidelines 151-20, 151-21, and  151-22; the second would cover Guidelines 151-23 and
151-25; the third would cover  Guideline 151-26.

       Note particularly that product chemistry studies are likely to  contain Confidential
Business Information as defined  in FIFRA §10(d)(l)(A), (B), or (C), and if so must be
handled as described in section D.3.  of this notice.

       c.  Residue Chemistry Studies.  Guidelines 171-4, 153-3, and 153-4 are extremely


                                           84

-------
broad in scope; studies addressing residue chemistry requirements must thus be defined at a
level below that of the Guideline code.  The general principle, however, of limiting a study to
the report of a single investigation still applies fully.  Data should be treated as a single study
and bound separately for each analytical method, each report of the nature of the residue in a
single crop or animal species, and for each report of the magnitude  of residues resulting from
treatment  of a single crop or from processing a single crop.  When  more than one commodity
is derived from a single crop (such as beet tops and beet roots) residue data on all such
commodities should be reported as a single study. When multiple field trials are associated
with a single crop, all such trials should be reported as a single study.

D.     Organization of Each Study Volume

       Each complete study must include all applicable elements in the list below, in the order
indicated.  (Also see Page 17.) Several  of these elements are further explained in the following
paragraphs.   Entries in the column headed "example" cite the page number  of this notice

D.I.   Title Page

       A title page is always required for each submitted study, published or unpublished.
The title page must always be freely releasable to requestors; DO NOT INCLUDE CBI ON
THE TITLE PAGE.  An example of an acceptable title page is on page  12 of this notice.
The following information must appear on the title page:

a.      Study title. The study title should be as descriptive as possible It must clearly identify
the substance (s) tested and correspond to the name of the data requirement as it appears in the
Guidelines.
                                           85

-------
b.     Data requirement addressed.  Include on the title page the Guideline number (s) of the
specific requirement(s) addressed by the study.

c.     Author (s).  Cite only individuals with primary intellectual responsibility for the content
of the study.  Identify them plainly as authors, to distinguish them from the performing
laboratory, study sponsor, or other names that may also appear on the title page.

d.     Study Date.  The title page must include a single date for the study. If parts of the
study were performed at different times, use only the date of the latest element in the study.

e.     Performing Laboratory Identification.  If the study reports work done by one or more
laboratories, include on the title page the name and address  of the performing laboratory or
laboratories, and the laboratory's internal project number (s) for the work. Clearly distinguish
the laboratory's project identifier from  any other reference numbers provided by the study
sponsor or submitter.

f.      Supplemental Submissions. If the study is a commentary on or supplement to another
previously submitted study, or if it responds to EPA questions raised with respect to an earlier
study, include on the title page elements a. through d. for the previously submitted study,
along with the EPA Master Record Identifier  (MRID) or Accession number of the earlier
study if you know these numbers.  (Supplements submitted in the same submittal package as
the primary study should be appended to and bound with the primary study.   Do not include
supplements to more than one study under a single title  page).

g.      Facts of Publication.  If the study is a reprint of a published document, identity on the
title page all relevant facts of publication, such as the journal title, volume, issue, inclusive
page numbers, and publication date.


D.2.   Statements of Data Confidentiality Claims Under FIFRA  §10(d)(l).

       Each submitted study must be accompanied by one of the two alternative forms of the
statement  of Data Confidentiality Claims specified in the proposed regulation in §158.33 (b)
and (c)  (See Attachment 3).  These statements apply only to claims of data confidentiality
based on FIFRA §10(d)(l)(A), (B), or  (C).  Use the appropriate alternative form of the
statement  either to assert a claim of §10(d)(l) data confidentiality (§158.33(b)) or to waive
such a claim (§158.33(c)).  In either  case, the statement must be signed  and dated, and must
include  the typed name and title of the official who signs it.  Do not make CBI claims with
respect to  analytical methods associated with pet-itions for tolerances or emergency
exemptions (see NOTE Pg  13).

D.3.   Confidential Attachment

       If the claim is made that a study includes confidential business information as defined
by the criteria of FIFRA §10(D)(1)(A), (B), or (C) (as described in D.2. above) all such
information must be excised from the body of the study and confined to a separate
study-specific Confidential Attachment. Each  passage of CBI so isolated must be identified by
a reference number cited within the body of the study at the point from which the passage was
excised (See Attachment 5).

       The Confidential Attachment to  a study must be  identified by a cover sheet fully
identifying the parent study, and must be clearly marked "Confidential Attachment."  An
appropriately annotated photocopy of the parent study title page may be used  as this cover
sheet.  Paginate the Confidential Attachment separately  from the body of the study, beginning
with page  1 of X on the title page. Each passage confined to the Confidential Attachment
must be associated with a specific cross reference to the page(s) in the main body of the study
on which it is cited, and with a reference to the applicable passage(s) of FIFRA §10(d)(l) on
which the  confidentiality claim is based.

D.4.   Supplemental Statement of Data Confidentiality Claims (See
       Attachment 4)
                                           86

-------
       If you wish to make a claim of confidentiality for any portion of a submitted study
other than described by FIFRA §10(d) (1)(A), (B), or (C), the following provisions apply:

       - The specific information to which the claim applies must be clearly marked in the
       body or the study as subject to a claim of confidentiality.

       - A Supplemental Statement of Data Confidentiality Claims must be submitted,
       identifying each passage claimed confidential and describing in detail the basis for the
       claim.  A list of the points to address in such a statement is included in Attachment 4
       on Pg 14.

       - The Supplemental Statement  of Data Confidentiality Claims must be signed and dated
       and must include the typed name and title of the official who signed it.

D.5.   Good Laboratory Practice Compliance Statement

       This statement is required if the study contains laboratory work subject to GLP
requirements specified in 40 CFR  160.  Samples of these statements are shown in Attachment
6.

E.     Reference to Previously Submitted Data

       DO NOT RESUBMIT A STUDY THAT HAS PREVIOUSLY BEEN SUBMITTED
FOR ANOTHER PURPOSE unless  EPA specifically requests it.   A copy of the title page
plus the MRID number (if known) is sufficient to allow us to retrieve the study immediately
for review. This prevents  duplicate entries in the Agency files, and saves you
the cost of sending more copies of the study.  References to previously submitted studies
should not be included in the transmittal document, but should be incorporated into the
statemenTof the method of support for the application.

F.     Physical Format Requirements

       All elements in the  data submittal package must be on uniform 8 1/2 by 11 inch white
paper,  printed on one side  only in black ink, with high contrast and good resolution.  Bindings
for individual studies must be secure,  but easily removable to permit disassembly for
microfilming.  Check with EPA for special instructions before submitting data in any medium
other than paper, such as film or magnetic media.

Please  be particularly attentive to the following points:

       •     Do not include frayed or torn pages.

       •     Do not include carbon copies, or copies in other than black ink.

       •     Make sure that photocopies are clear, complete, and fully readable.

       •     Do not include oversize computer printouts or fold-out pages.

       •     Do not bind any documents with glue or binding tapes.

       •     Make sure that all pages of each study,  including any attachments or
             appendices,  are present and in correct sequence.

       Number of Copies Required - All submittal packages except those associated with a
Registration Standard or Special Review (See Part G below) must be provided  In three
complete, identical copies. (The proposed regulations specified two copies; three are now
being required to expedite  and reduce the cost of processing data into the OPP  Pesticide
Document Management System and getting it into review.)

G.     Special Requirements for Submitting Data to the Docket

       Data submittal packages associated with a Registration Standard or Special Review
must be provided in four copies, from one of which all material claimed as CBI has been


                                          87

-------
excised.  This fourth copy will become part of the public docket for the RS or SR case. If no
claims of confidentiality are made for the study, the fourth copy should be identical to the
other three.  When portions of a study submitted in support or an RS or SR are claimed as
CBI, the first three copies will include the CBI material as provided in section D of this
notice.  The following special preparation is required for the fourth copy.

               STATEMENT OF DATA CONFIDENTIALITY CLAIMS

NOTE: Applicants for permanent or temporary tolerances should note that it is OPP policy
that no permanent tolerance, temporary tolerance, or request for an emergency exemption
incorporating an analytical method,  can be approved unless the applicant waives all claims of
confidentiality for the analytical method.  These analytical methods are published in the FDA
Pesticide Analytical Methods Manual, and therefore cannot be claimed as confidential. OPP
implements this policy by returning submitted analytical methods, for which confidentiality
claims have been made, to the submitter, to obtain the confidentiality waiver before they can
be processed.

         NOTICE  TO MANUFACTURERS,  PRODUCERS,  FORMULATORS,
                  AND REGISTRANTS OF PESTICIDES

ATTENTION: Persons Responsible for Federal Registration of
Pesticide Products.

SUBJECT: Accuracy of Stated Percentages for Ingredients
Statement

I.  PURPOSE:

     The purpose of this notice is to clarify the Office of
Pesticide P^gram's P9licy with respect to the statement of
percentages in a pesticide's label's ingredient statement.
Specifically, the amount  (percent by weight) of ingredient(s)
specified in the ingredient statement on the label must be stated
as the nominal concentration of such ingredient(s), as that  term
is defined in 40 CFR 158.153(1). Accordingly, the Agency has
established the nominal concentration as the only acceptable
label claim for the amount of active ingredient in the product.

II.  BACKGROUND

     For some time the Agency has accepted two different methods
9f identifying on the label what percentage is claimed for the
ingredient(s) contained in a pesticide. Some applicants claimed a
percentage which represented a level between the upper and the
lower certified limits. This was referred to as the nominal
concentration. Other applicants claimed the lower limit as the
percentage of the ingredient(s) that would be expected to be
present in their product at the end of the product's shelf-life.
Unfortunately, this led to a great deal of confusion among the
regulated industry, the regulators, and the consumers as to
exactly how much of a given ingredient was in a given product.
The Agency has established the nominal concentration as the  only
acceptable label claim for the amount of active ingredient in the
product.

     Current regulations require that the percentage listed  in
the active ingredient statement be as precise as possible
reflecting go9d manufacturing practices 40 CFR 156.10(g)(5). The
certified limits required for each active ingredient are intended
to encompass any such "good manufacturing practice" variations 40
CFR 158.175(c)(3).

     The upper and lower certified limits, which must be proposed
in connection with a product's registration, represent the
amounts of an ingredient that may legally be present 40 CFR
158.175. The lower certified limit is used as the enforceable
lower limit for the product composition according to FIFRA
section 12(a)(1)(C),  while the nominal concentration appearing on
the label would be the routinely achieved concentration used for
calculation of dosages and dilutions.

     The nominal concentration would in fact state the greatest
degree of accuracy that is warranted with respect to actual


                                99

-------
product compositi9n because the nominal concentration would be
the amount of active ingredient typically found in the product.

     It is imp9rtant for registrants to note that certified
limits for active ingredients are not considered to be trade
secret information under FIFRA section 10(b).  In this respect the
certified limits will be routinely provided by EPA to States for
enforcement purposes, since the nominal concentration appearing
on the label may not represent the enforceable composition for
purposes of section 12(a)(1)(C).

III. REQUIREMENTS

     As described below under Unit V. " COMPLIANCE SCHEDULE," all
currently registered products as well as all applications for new
registration must comply with this Notice by specifying the
nominal C9ncentrati9n expressed as a percentage by weight as the
label claim in the ingredient(s)  statement and equivalence
statements if applicable (e.g., elemental arsenic, metallic zinc,
salt of an acid).  In addition, the requirement for performing
sample analyses of five or more representative samples must be
fulfilled. C9pies of the raw analytical data must be submitted
with the nominal ingredient label claim. Further information
about the analysis requirement may be found in the 40 CFR
158.170. All products are required to pr9vide certified limits
for each active, inert ingredient, impurities of toxicological
significance(i. e.,  upper limit(s) 9nly) and on a case by case
basis as specified by EPA.  These limits are to be set based on
representative sampling and chemical analysis(i.e., quality
control) of the product.

     The format of the ingredient statement must conform to 40
CFR 156-Labeling Requirements For Pesticides and Devices.

     After July 1,  1997, all pesticide ingredient Statements must
be changed to nominal concentration.

IV. PRODUCTS THAT REQUIRE EFFICACY DATA

     All pesticides are required to be efficacious. Therefore,
the certified lower limits may not be lower then the minimum
level to achieve efficacy.  This is extremely important for
products which are intended to C9ntrol pests which threaten the
public health, e.g., certain antimicrobial and rodenticide
products. Refer to 40 CFR 153.640.

     In those cases where efficacy limits have been established,
the Agency will not accept certified lower limits which are below
that level for the shelf life of the product.

V. COMPLIANCE SCHEDULE

     As described earlier,  the purpose of this Notice is to make
the registration process more uniform and more manageable for
both the agency and the regulated community. It is the Agency's
intention to implement the requirements of this notice as
smoothly as possible so as not to disrupt or delay the Agency's
high priority programs,  i.e.,  reregistration,  new chemical, or
fast track (FIFRA section 3(c)(3)(B). Therefore,
applicants/registrants are expected to comply with the
requirements of this Notice as follows:

     (1)  Beginning July 1, 1991, all new product registrations
          submitted to the Agency are to comply with the
          requirements of this Notice.
                               100

-------
     (2)  Registrants having products subject to reregistration
          under FIFRA section 4(a) are to comply with the
          requirements of this Notice when specific products are
          called in by the Agency under Phase V of the
          Reregistration Program.

     (3)  All other products/applications that are not subject to
          (1) and  (2) ab9ve will have until July 1, 1997, to
          comply with this Notice. Such applications should note
          "Conversion to Nominal Concentrations on the
          application form. These types Or amendments will not be
          handled as "Fast Track" applications but will be
          handled as routine requests.

SECTION I.  WHY YOU ARE RECEIVING THIS NOTICE

      The Agency has reviewed existing data for this active ingredient(s) and reevaluated the
data needed to support continued registration of the subject active ingredient(s).  This reevaluation
identified additional data necessary to assess the health and safety of the continued use of products
containing this active ingredient(s). You have been sent this Notice because you have product(s)
containing the subject active ingredient(s).

SECTION II. DATA REQUIRED BY THIS NOTICE

      A.     DATA REQUIRED

             The data required by this Notice are specified in Attachment 3,  Requirements
      Status and Registrant s Response Form.  Depending on the results of the studies required
      in this Notice, additional testing may be required.

      B.     SCHEDULE FOR SUBMISSION OF DATA

             You are required to submit the data or otherwise satisfy the  data requirements
      specified in Attachment 3, Requirements Status and Registrant's Response Form, within
      the time frames provided.
       C.     TESTING PROTOCOL

             All studies required under this Notice must be conducted in accordance with test
       standards outlined in the Pesticide Assessment Guidelines for those studies for which
       guidelines have been established.

             These EPA  Guidelines are  available from the National Technical Information
       Service (NTIS), Attn: Order Desk, 5285 Port Royal Road, Springfield, Va 22161 (tel:
       703-487-4650).

             Protocols approved  by  the  Organization  for  Economic  Cooperation  and
       Development (OECD)  are also acceptable if the OECD-recommended test standards
       conform to  those specified in the Pesticide Data Requirements regulation (40 CFR §
       158.70).  When using the OECD protocols, they should be modified as appropriate so that
       the data generated by the study will satisfy the requirements  of 40 CFR §  15o. Normally,
       the Agency  will not extend deadlines for  complying with data requirements when the
       studies were  not conducted in accordance with acceptable standards.  The OECD protocols
       are available from OECD, 1750 Pennsylvania Avenue N.W., Washington, D.C. 20006.

             All new studies and proposed protocols submitted in response to this Data Call-In
       Notice must  be in accordance with Good Laboratory Practices  [40 CFR Part 160.3(a) (6)].

       D.    REGISTRANTS  RECEIVING  PREVIOUS SECTION  3(c)(2)(B) NOTICES
             ISSUED BY  THE AGENCY

             Unless otherwise noted herein, this Data Call-in does not in any way supersede or
       change the requirements of any previous Data Call-in(s), or any other agreements entered
       into with the Agency pertaining to such prior Notice.  Registrants must comply with the
       requirements  of all Notices to avoid  issuance of a Notice  of Intent to Suspend their
       affected products.


SECTION III.       COMPLIANCE WITH REQUIREMENTS OF THIS NOTICE

       A.    SCHEDULE FOR RESPONDING TO THE AGENCY

              The appropriate responses initially required by this Notice must be submitted to
       the Agency within 90 days after your receipt of this Notice. Failure to adequately respond
       to this Notice within 90 days of your receipt will be a basis for issuing a Notice of Intent
       to Suspend (NOIS)  affecting your products. This and other bases for issuance  of NOIS due
       to failure  to comply with this Notice are presented in Section IV-A and IV-B.

             B.     OPTIONS FOR RESPONDING TO THE AGENCY

             The options for responding to this Notice are:  1) voluntary cancellation, 2)  delete
       use(s),  (3)  claim  generic data exemption,  (4) agree to satisfy  the data requirements
       imposed by this Notice or (5) request a data waiver(s).

             A  discussion of how to respond if you chose the Voluntary Cancellation option, the
       Delete Use(s) option  or  the  Generic Data  Exemption  option is presented below.  A
       discussion of the various options available  for satisfying the data  requirements of this
       Notice is contained in Section III-C. A discussion  of options relating to requests for data
       waivers is contained in Section III-D.

             There are two forms that accompany this Notice of which, depending upon your
       response,  one or both must be used in your response to the Agency.  These forms are the
       Data-Call-in Response Form (Attachment 2) and the Requirements  Status and Registrant's
       Response  Form (Attachment 3). The Data Call-In Response  Form must be submitted as
       part  of every response  to this Noticed  Flease note  that  the  company's authorized
       representative is required to sign the first page of the Data Call-in Response Form and
       Requirements Status and Registrant's Response Form (if this form is required) and initial
       any subsequent pages. The forms contain separate detailed instructions on the response
       options.  Do not alter the printed material.  If you have questions or need assistance in
       preparing your response, call or write the contact person identified in Attachment 1.

             1.      Voluntary Cancellation - You may avoid the requirements of this Notice  by
             requesting  voluntary  cancellation of your  product(s)  containing the  active
             ingredient (s) that  is the subject of  this Notice. If you wish  to voluntarily cancel
             your  product,  you must submit  a completed  Data Call-In Response Form
             indicating your  election of this option. Voluntary cancellation is item number b
             on the Data Call-In Response Form. If you choose this option, this is the only form
             that you are required to complete.

                    If you  choose to voluntarily cancel your  product,  further  sale and
             distribution of your product after the effective date  of cancellation must be in
             accordance with the Existing Stocks provisions of this  Notice which are contained
             in  Section IV-C.
                                         107

-------
2.     Use  Deletion  -  You may avoid the requirements  of this Notice  by
eliminating the uses or your product to which the requirements apply. If you wish
to amend your registration to delete uses, you must submit the Requirements Status
and Registrant's Response Form, a completed application for amendment, a copy
of your  proposed amended  labeling,  and  all  other information required for
processing the application.  Use deletion is option number 7 on the Requirements
Status and Registrant's Response Form. You must also complete a Data Call-In
Response Form by signing the certification, item number 8. Application forms for
amending registrations  may be  obtained from the Registration Support and
Emergency Response Branch, Registration Division, (703)  308-8358.

       If you choose to delete the use(s) subject to this Notice or uses subject to
specific data requirements, further sale, distribution,  or use of your product after
one year from the due date of your 90 day response, must bear an amended label.

3.     Generic Data Exemption - Under section 3(c)(2)(D) of FIFRA, an applicant
for  registration of a product is exempt from  the requirement to submit or cite
generic data  concerning an active ingredient(s)  if the active  ingredient(s) in the
product is derived exclusively from  purchased,  registered pesticide products
containing the  active  ingredient(s).   EPA has concluded,  as an exercise of its
discretion, that it normally will not suspend the registration  of a product which
would qualify and continue  to qualify for the generic data exemption in section
3(c)(2)(D) of  FIFRA. To qualify, all of the following requirements must be met:

       a.      The active ingredient(s) in your registered product must be present
       solely because  of incorporation of  another registered product  which
       contains the subject active ingredient(s) and is purchased from a source not
       connected with you; and,

       b.      every  registrant  who   is  the  ultimate  source  of  the  active
       ingredient (s) in your product subject to this DCI must be in compliance
       with the requirements of this Notice and must remain in compliance; and

       c.      you must  have provided  to  EPA an  accurate and  current
       "Confidential Statement of Formula" for each of your products to which
       this Notice applies.

       To apply for the Generic Data Exemption you must submit a completed
Data Call-in Response Form,  Attachment 2 and  all supporting documentation. The
Generic Data Exemption is item number 6a on the Data Call-In Response Form.
If you claim a generic data exemption you  are  not required to complete the
Requirements Status and Registrant s Response Form.  Generic Data Exemption
cannot be selected as an option for product specific data.

       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 registrant^)
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 Call-In 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 and their product(s), unless you commit to submit and do submit the
required data within the specified time. In such cases the Agency generally will
not grant a time extension for submitting the data.

4.     Satisfying the Data Requirements of this Notice -  There are various options
available  to  satisfy the data requirements  of this Notice.  These options are

                             108

-------
       discussed in Section III-C of this Notice and comprise options 1 through 6 on the
       Requirements Status and Registrant's Response Form and option 6b and 7 on the
       Data Caii-ln Response Form! it you choose  option 6b or 7, you must submit both
       forms as well as any  other information/data pertaining to the option chosen to
       address the data requirement.

       5.     Request for Data Waivers. Data waivers are discussed in Section III-D of
       this Notice and are covered by  options 8 and 9 on the Requirements Status and
       Registrant's Response Form. If you choose one of these options, you must submit
       both forms as well as any other  information/data pertaining to the option chosen
       to address the data requirement.

C.     SATISFYING THE DATA REQUIREMENTS OF THIS NOTICE

       If you acknowledge on the Data Call-in Response Form that you agree to satisfy
the data requirements (i.e. you  select option 6b and/or '(), then you must select one of the
six options on the Requirements Status  and Registrant's Response Form related to data
production for each data requirement.  Your option selection should be entered under item
number 9, "Registrant Response." The six options related to data production are the first
six options discussed under item 9 in the instructions for completing the Requirements
Status and Registrant's Response Form.  These six options are listed immediately below
with  information in parentheses to guide registrants to additional instructions provided in
this Section. The options are:

       1.     I will generate and submit data within the specified time frame (Developing
             Data),

       2.     I have entered into an  agreement with one or more registrants to develop
             data jointly (Cost Sharing),

       3.     I have made offers to cost-share (Offers to Cost Share),

       4.     I am submitting an existing study that has not been submitted previously to
             the Agency by  anyone  (Submitting an Existing Study),

       5.     I am  submitting or citing data to upgrade a study classified  by EPA as
             partially acceptable and upgradeable (Upgrading a Study),

       6.     I am  citing an  existing study that EPA has classified as acceptable or  an
             existing study that has been submitted but not reviewed by the Agency
              (Citing an Existing Study).

       Option 1, Developing  Data —

             If you choose to develop the required data it must be in conformance with
       Agency deadlines and with other Agency requirements as referenced herein and in
       the attachments. All data generated and submitted must comply with the Good
       Laboratory Practice (GLP) rule (40 CFR Part 160), be conducted according to the
       Pesticide  Assessment  Guidelines  (PAG),  and  be in  conformance with the
       requirements of PR Notice 86-5.  In addition, certain studies require Agency
       approval of test protocols in advance of study  initiation.  Those studies for which
       a protocol must be submitted have been identified in the Requirements Status and
       Registrant's Response  Form and/or footnotes to the form.  It you wish to use a
       protocol which differs from the  options discussed in Section II-C of this Notice,
       you must submit a detailed description of the proposed protocol and your reason
       for wishing to use it.  The Agency may choose to reject a protocol not specified

                                   109

-------
in Section II-C.   If the Agency rejects your protocol you will be notified in
writing, however, you should be aware that rejection of a proposed protocol will
not be a basis for extending the deadline for submission or data.

       A progress report must be submitted for each study within 90 days from the
date you are required to commit to generate  or undertake some other means to
address that study requirement, such as making an offer to cost-share or agreeing
to share in the cost of developing that study.  A 90-day progress report must be
submitted for all  studies.  This 9T)-day progress report must include the date the
study was or will be initiated and, for studies to be started within  12 months of
commitment, the name and address of the laboratory(ies) or individuals who are
or will be conducting the study.

       In addition, if the time frame for submission of a final report is more than
1 year, interim reports must be submitted at 12 month intervals from the date you
are required to commit to generate or otherwise address the requirement for the
study. In addition to the other information specified in the preceding paragraph,
at a minimum,  a brief description of current activity on and the status of the study
must be included as well as a full description of any problems encountered since
the last progress report.

       The time  frames in the Requirements Status and Registrant's Response
Form are the  time frames that the Agency  is allowing for the submission of
completed study reports or protocols. The noted deadlines run from the date of
the receipt of this Notice by the registrant.  If the data are not submitted by the
deadline, each registrant is subject to receipt of a Notice of Intent to Suspend the
affected registration(s).

       If you cannot submit the data/reports to the Agency in the time required by
this Notice and intend to seek additional time to meet the requirement(s), you must
submit a request to the Agency which includes:  (1) a detailed description of the
expected difficulty and (2) a proposed  schedule  including alternative  dates for
meeting such requirements on a step-by-step basis.  You must explain any technical
or  laboratory  difficulties and provide  documentation  from  the laboratory
performing  the testing.   While EPA is considering your request, the original
deadline remains.  The Agency will respond to your request in writing. If EPA
does not grant your request, the original deadline remains.  Normally, extensions
can  be requested only  in cases of extraordinary testing problems beyond the
expectation or control of the registrant.  Extensions will not be given in submitting
the 90-day responses.    Extensions will not be  considered if  the request for
extension is not made in a timely fashion;  in no event shall an extension request be
considered if it is submitted at or after the lapse of the subject deadline.

Option  2, Agreement to Share in Cost to Develop Data  —

       If you choose to enter into an agreement to share in the cost of producing
the required data but will not be submitting the data yourself, you must provide the
name of the registrant who will be submitting the data. You must also provide
EPA with documentary evidence that  an agreement  has been  formed.  Such
evidence may be your  letter  offering to join  in an agreement and  the other
registrant's acceptance of your offer, or a written statement by the parties that an
agreement exists.  The agreement to produce the data need not specify all of the
terms of the final arrangement between the parties or the mechanism to resolve the
terms.  Section 3(c)(2)(B) provides that if the parties cannot resolve the terms of
the agreement they may resolve their differences through binding arbitration.
                             110

-------
Option 3, Offer to Share in the Cost of Data Development —

       If you have made an offer to pay in an attempt to enter into an agreement
or amend an existing agreement to meet the requirements of this Notice and have
been unsuccessful, you may request EPA (by selecting this option) to exercise its
discretion not to suspend your registration (s), although you do not comply with the
data submission requirements of this Notice. EPA has determined that as a general
policy, absent other relevant considerations, it will not suspend the registration of
a product of a registrant who  has in good faith sought and continues  to seek to
enter into a joint data development/cost sharing program, but the other registrant(s)
developing the data has refused to accept your offer. To qualify for this option,
you must submit documentation to the Agency proving that you have made an offer
to another registrant (who has an obligation to submit data)  to share in the burden
of developing that data.  You  must also submit to the Agency a completed EPA
Form 8570-32, Certification of Offer to  Cost Share in the Development of Data.
In addition, you must demonstrate that the other registrant to whom the offer was
made has not accepted your  offer to  enter into a cost sharing agreement  by
including a  copy of your offer and  proof of the other registrant s receipt of that
offer  (such as a certified mail receipt).  Your offer must, in addition to anything
else, offer to share in the burden of producing the data upon terms to be agreed or
failing agreement to be bound by binding arbitration as provided by FIFRA section
3(c) (2) (B) (iii) and must not qualify this offer.   The other registrant must also
inform EPA of its election of an option to develop and submit the data required by
this Notice by submitting a Data Call-In Response Form and a Requirements  Status
and Registrant's  Response Form  committing to develop and  submit the data
required by  this Notice.

       In order for you to avoid  suspension under  this option, you may  not
withdraw your offer to share in the  burdens of developing the data.  In addition,
the other registrant must fulfill its commitment to  develop and submit the data as
required by this Notice.  If the other registrant fails to develop the  data or for some
other reason is 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 do submit the required data in the specified time frame.
In such cases, the Agency generally will not grant a time extension for submitting
the data.

Option 4, Submitting an Existing Study —

       If you choose to submit an  existing study in response to this Notice, you
must determine that the study  satisfies the requirements imposed by this Notice.
You may only submit a study that has not been previously submitted to the Agency
or previously cited by anyone.   Existing studies are studies which predate issuance
of this Notice.  Do not use this option if you are submitting data to  upgrade a
study.  (See  Option 5).

       You  should be aware that if the  Agency determines that the study is not
acceptable,  the Agency will require you to  comply  with  this  Notice,  normally
without  an  extension  of the  required date  of submission.   The Agency may
determine at any time that a study is not valid and needs to be repeated.

       To meet the requirements of the DCI  Notice for submitting an existing
study, all of the following three criteria must be clearly met:
                             111

-------
a.      You must certify at the time that the existing study is submitted that
the raw data and specimens from the  study are available for audit and
review and you must identify where they are available.  This must be done
in accordance with the requirements of the Good Laboratory  Practice
(GLP)  regulation, 40 CFR Part 160. As stated in 40 CFR 160.3(7) " raw
data means any laboratory  worksheets, records, memoranda, notes,  or
exact  copies thereof,  that  are the result  of original observations and
activities of a study and are necessary for the reconstruction and evaluation
of the report of that study. In the event that exact transcripts of raw data
have been prepared (e.g., tapes which  have been transcribed verbatim,
dated,  and verified accurate by signature), the  exact copy  or exact
transcript may be substituted for the original source as raw data. Raw data
may include photographs,  microfilm  or microfiche copies, computer
printouts,  magnetic media, including dictated observations, and recorded
data from automated instruments."  The term "specimens", according to  40
CFR  160.3(7), means "any  material  derived from  a test  system for
examination or analysis."

b.      Health  and safety  studies completed after  May 1984 must also
contain all GLP-required quality assurance and quality control information,
pursuant to the requirements of 40 CFR Part 160.  Registrants must also
certify at  the time of submitting the  existing study that such  GLP
information is available  for post-May  1984  studies  by  including  an
appropriate statement on or  attached to the study signed by an authorized
official or representative of the registrant.

c.      You must certify that each study fulfills the acceptance criteria for
the Guideline  relevant to  the study provided in the FIFRA Accelerated
Reregistration Phase 3 Technical Guidance and that the study has been
conducted  according to the Pesticide Assessment Guidelines (PAG)  or
meets  the purpose of the PAG (both available from NTIS).  A study not
conducted according  to the  PAG may  be  submitted  to the Agency for
consideration if the registrant believes  that the study clearly meets the
purpose of the PAG.  The registrant is referred to 40 CFR 158.70 which
states the Agency's policy regarding acceptable protocols. If you wish to
submit the study,  you must, in addition to certifying that the purposes of
the PAG  are met by  the  study,  clearly articulate the rationale why you
believe the study  meets the purpose of the PAG, including copies of any
supporting information or  data. It has been the Agency's experience that
studies completed prior to January 1970 rarely satisfied the purpose of the
PAG and that necessary raw data are usually not available for such studies.
       If you submit an existing study, you must certify that the study
meets all requirements of the criteria outlined above.

       If EPA has previously reviewed  a protocol for a study you are
submitting, you must identify any action taken  by the Agency on the
protocol and must indicate, as part of your certification, the manner in
which all Agency comments, concerns, or issues were addressed in the
final protocol and study.

       If you know of a study pertaining to any requirement in this Notice
which does not meet the criteria outlined  above but does contain factual
information regarding unreasonable adverse effects, you must notify the

                       112

-------
             Agency of such a study.  If such a study is in the Agency's files, you need
             only cite it along with the notification. If not in the Agency's files, you
             must submit a summary and copies as required by PR Notice 86-5.

       Option 5, Upgrading a Study —

             If a study has been classified as partially acceptable and upgradeable, you
       may submit data to upgrade that study.  The Agency will review the data submitted
       and determine if the  requirement  is  satisfied.   If the Agency  decides  the
       requirement is not satisfied, you may still be required to submit new data normally
       without any time extension. Deficient,  but upgradeable studies will normally be
       classified as supplemental.  However, it is important to note that not all studies
       classified as supplemental are upgradeable.  If you have questions regarding the
       classification  of a study or whether a study may be upgraded, call or write the
       contact person listed in Attachment 1. If you submit data to upgrade an existing
       study you must satisfy or supply information to correct all deficiencies in the study
       identified by  EPA.  You must provide a clearly articulated rationale of how the
       deficiencies have been remedied or corrected and why the study should be rated
       as acceptable to EPA. Your submission must also specify the MRID number(s) of
       the study which you are attempting to upgrade and must be in conformance with
       PR Notice 86-5.

             Do  not submit additional data for the  purpose of upgrading a study
       classified as unacceptable and determined by the Agency as not capable of being
       upgraded.

             This option should also be used to cite  data that  has been previously
       submitted to upgrade a study, but has not yet been  reviewed by the Agency. You
       must provide the MRID number of  the data submission as well as the  MRID
       number of the study being upgraded.

             The criteria  for submitting an existing study,  as specified  in Option 4
       above, apply  to all data submissions  intended to  upgrade studies.  Additionally
       your submission  of data intended to upgrade studies must be accompanied by a
       certification that you comply with each of those criteria as well as a certification
       regarding protocol compliance with Agency requirements.

       Option 6, Citing Existing Studies —

             If you choose to cite a study that has been previously submitted to EPA,
       that study must have been previously classified by EPA as acceptable or it must be
       a study which has not yet been reviewed by the Agency. Acceptable toxicology
       studies generally will have been classified as  'core-guideline"  or  ' core minimum.'
       For ecological effects studies, the classification generally would be a rating of
       "core."  For all other disciplines the classification would be "acceptable."  With
       respect to any  studies for which you wish to select this option you must provide the
       MRID number of the study you are citing and, if the study has  been reviewed by
       the Agency, you  must provide the Agency's classification of the study.

             If you  are citing a study of which you are not the original data submitter,
       you must submit a completed copy of EPA Form 8570-31, Certification with
       Respect to Data Compensation Requirements.

D.     REQUESTS FOR DATA WAIVERS
                                   113

-------
       There are two types of data waiver responses to this Notice.  The first is a request
for a low volume/minor use waiver and the second is a waiver request based on your
belief that the data requirement^) are inapplicable and do not apply to your product.

       1.     Low Volume/Minor Use Waiver —  Option 8 on the Requirements  Status
       and Registrant's Response Eorm.  Section 3(c)(2) (A) of FIFKA requires EPA to
       consider the appropriateness of requiring data for low volume, minor use
       pesticides. In implementing this provision EPA considers as low volume pesticides
       only those active ingredient (s) whose total production volume for all pesticide
       registrants is small.  In determining whether to grant a low volume,  minor use
       waiver  the  Agency  will consider the extent, pattern and volume of use, the
       economic incentive to conduct the testing, the importance of the pesticide, and the
       exposure and risk from use of the pesticide. If an active ingredient (s) is used for
       both high volume and low volume uses,  a low volume exemption will not be
       approved.  If all uses  of an active ingredient(s) are low volume and the combined
       volumes for all uses are also low, then an exemption may be granted,  depending
       on review of other information outlined below. An exemption will not be granted
       if any registrant of the active ingredient(s) elects to conduct the testing.  Any
       registrant receiving a low volume minor use waiver must remain within the sales
       figures in their forecast supporting the waiver request in order to remain qualified
       for such waiver.  If granted a waiver, a registrant will be required, as a condition
       of the waiver, to submit annual sales reports. The Agency will respond to requests
       for waivers in writing.

             To apply for a low volume, minor  use  waiver, you must submit the
       following  information, as applicable to your  product(s), as part of your 90-day
       response to this Notice:

             a.     Total  company  sales  (pounds  and  dollars) of all  registered
             product(s) containing  the active ingredient(s). If applicable  to the  active
             ingredient(s), include foreign sales for those products that are not registered
             in this country but are applied to sugar (cane or beet),  coffee, bananas,
             cocoa, and other such crops. Present the above information by year for
             each of the past five years.

             b.     Provide an estimate of the sales (pounds and dollars) of the  active
             ingredient (s) for each  major use site.  Present the above information by
             year  for each  of the past five years.

             c.     Total  direct production cost of product (s) containing  the  active
             ingredient (s)  by year for the past five years. Include information on raw
             material cost,  direct labor cost, advertising, sales and marketing, and any
             other significant costs  listed separately.

             d.     Total indirect production cost (e.g. plant overhead, amortized plant
             and equipment) charged to product(s) containing the active ingredient(s) by
             year for the past five years.  Exclude all non-recurring costs that were
             directly related to the active ingredient (s), such  as   costs  of  initial
             registration and any data development.

             e.     A list  of each  data requirement  for  which you seek  a waiver.
             Indicate the type of waiver  sought and the estimated cost to you  (listed
             separately for  each data requirement and associated test) of conducting the
             testing needed to fulfill each of these data requirements.
                                    114

-------
              f.      A list of each data requirement for which you are not seeking any
              waiver and the  estimated  cost to you (listed separately for each data
              requirement and associated test) of conducting the testing needed to fulfill
              each of these data requirements.

              g.      For each of the next ten years, a year-by-year forecast of company
              sales (pounds and dollars)  of the active ingredient(s), direct production
              costs  of  product(s)  containing the  active  ingredient(s)  (following the
              parameters  in item  c above), indirect production costs  of  product(s)
              containing the active ingredient(s)  (following the parameters in item d
              above), and costs of data development pertaining to the active ingredient (s).

              h.      A description of the importance and unique benefits of the active
              ingredient (s) to users. Discuss the use patterns and the effectiveness of the
              active  ingredient(s)  relative  to  registered  alternative chemicals  and
              non-chemical control strategies.  Focus on benefits unique  to the active
              ingredient(s), providing information that is as quantitative as possible.  If
              you do not have quantitative data upon which to base your estimates, then
              present the reasoning used to derive your estimates.  To assist the Agency
              in determining the degree of importance of the active  ingredient (s) in terms
              of its benefits, you should provide information on any of the following
              factors, as applicable to your product(s):

                     (1)     documentation of the usefulness of the active ingredient (s)
              in Integrated Pest Management, (b) description of the beneficial impacts on
              the  environment  of  use  of the  active  ingredient(s), as opposed to its
              registered alternatives, (c)  information on the breakdown of the active
              ingredient(s)  after use and on its persistence in the  environment, and (d)
              description of its usefulness against a pest(s) of public health significance.

       Failure to submit sufficient information for the Agency to make a determination
regarding a request for a low volume minor use waiver will result in denial of the request
for a waiver.

       2.      Request for Waiver of Data  —Option 9 on the Requirements  Status and
       Registrant s Response FofrrT  This  option may be used  if you believe that a
       particular data requirement should not apply because the corresponding use is no
       longer registered  or the requirement is inappropriate.  You  must submit a rationale
       explaining why you believe the data requirements should not apply.  You must also
       submit the current label(s)  of your product(s) and,  if a current copy of your
       Confidential Statement of Formula is not already  on file you must submit a current
       copy.

              You will be informed of the Agency's decision in writing. If the Agency
       determines that  the data requirements  of this Notice  do not  apply  to  your
       product (s),  you will not be  required to supply  the  data pursuant  to section
       3(c)(2)(B).  If EPA determines that the data are required for your product(s), you
       must choose a  method of meeting the requirements of this Notice within the time
       frame provided by this Notice.  Within 30 days of your receipt of the Agency's
       written decision, you must submit a revised Requirements Status and Registrant's
       Response Form indicating the option chosen.

IV.    CONSEQUENCES OF FAILURE TO COMPLY WITH THIS NOTICE

       A.    NOTICE OF INTENT TO SUSPEND

             The Agency may issue a Notice of Intent to Suspend products subject to this Notice
       due to failure by a registrant to comply with the requirements of this Data Call-In Notice,
       pursuant to FIFRA section 3(c)(2)(B). Events which may be the basis for issuance of a
       Notice of Intent to Suspend include, but  are not limited to, the following:

             1.      Failure to respond as required by this Notice within 90 days of your receipt
                    of this Notice.

             2.      Failure to submit on the required schedule an acceptable proposed or final

                    this Notice.

             5.      Failure to take a required action or  submit adequate information pertaining
                    to any option chosen to address the data requirements (e.g., any required
                    action or information pertaining to submission or citation of existing studies
                    or  offers, arrangements,  or  arbitration on the sharing  of costs or the
                    formation of Task Forces, failure to comply with the terms  of an agreement
                    or arbitration concerning joint data development or failure to comply with

                    cost of developing data and provided proof of the registrant's receipt of
                    such offer, or failure of a registrant on whom you rely for a generic data
                    exemption either to:

                    a.      inform EPA of intent to develop and submit the data required by
                    this Notice on a Data Call-In Response Form and a Requirements Status
                    and Registrant's Response Form;  of,

                    b.      fulfill  the commitment to develop  and  submit the  data as required
                    by this Notice; or,

                    c.      otherwise take appropriate steps to meet the requirements stated in
                    this Notice, unless you commit to  submit and do submit the required data

       B.    BASIS   FOR   DETERMINATION   THAT   SUBMITTED   STUDY   IS
             UNACCEPTABLE


                                         116

-------
       The Agency may determine that a study (even if submitted within the required
time) is unacceptable and constitutes a basis for issuance of a Notice of Intent to Suspend.
The grounds for suspension include,  but are not limited to, failure to meet any of the
following:

       1.      EPA requirements specified in the Data Call-in Notice or other documents
       incorporated by reference (including, as applicable, EPA Pesticide Assessment
       Guidelines,  Data  Reporting  Guidelines, and GeneTox Health  Effects  Test
       Guidelines) regarding the design, conduct, and reporting of required studies.  Such
       requirements include, but are  not limited to, those relating to test material,  test
       procedures, selection of species, number  of animals,  sex and distribution of
       animals, dose and effect levels to be tested or attained,  duration of test, and, as
       applicable, Good Laboratory Practices.

       2.      EPA requirements regarding the submission of protocols, including the
       incorporation or any changes required by the Agency following review.

       3.      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 86-5.  All studies must be submitted in
       the form of a final report; a preliminary report will not be considered to fulfill the
       submission requirement.

C.     EXISTING STOCKS OF SUSPENDED OR CANCELLED PRODUCTS

       EPA has  statutory authority to permit continued  sale,  distribution and use of
existing stocks of a pesticide product which has been suspended or  cancelled if doing so
would  be consistent  with the purposes of the Federal  Insecticide, Fungicide,  and
Rodenticide Act.

       The Agency has determined that such disposition by registrants of existing stocks
for a suspended registration when a section 3 (c) (2) (B) data request  is outstanding would
generally not be consistent with the Act's purposes.  Accordingly, the Agency anticipates
granting  registrants permission to sell, distribute, or use existing  stocks of suspended
produces) only in exceptional circumstances.  If you believe such disposition of existing
stocks of your product(s) which may be suspended for failure to  comply with this Notice
should  be permitted, you have the burden of clearly demonstrating to EPA that granting
such permission would be consistent with the  Act. You must also explain 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, distribution, and use.  Unless you meet
this burden the Agency will not consider any request pertaining to the continued sale,
distribution, or use of your existing stocks after suspension.

       If you request a voluntary cancellation of your product(s) as a response to  this
Notice and your  product is in full compliance with all Agency requirements,  you will
have,  under most circumstances, one year  from the date  your  90  day response to  this
Notice  is due, to sell, distribute, or use  existing stocks.  Normally, the Agency will  allow
persons other than the registrant such as independent distributors, retailers and end users
to sell, distribute or use such existing stocks until the stocks  are exhausted. Any sale,
distribution  or use of stocks of voluntarily  cancelled products containing  an active
ingredient(s)  for which the Agency has particular risk concerns will be determined on
case-by-case basis.

       Requests for voluntary cancellation received  after the  90  day response period
required by this Notice will not result in the Agency granting any additional time to sell,

                                    117

-------
       distribute, or use existing stocks beyond a year from the date the 90 day response was due
       unless you demonstrate to the Agency that you are in full compliance with all Agency
       requirements,  including the requirements of this Notice.  For example, if you decide to
       voluntarily cancel your registration six months before a 3 year study is scheduled to be
       submitted, all progress reports and other information necessary to establish that you have
       been conducting the  study in an acceptable  and  good faith manner must have been
       submitted to the Agency, before EPA will consider granting an existing stocks provision.

SECTION V. REGISTRANTS' OBLIGATION TO REPORT POSSIBLE UNREASONABLE
             ADVERSE EFFECTS

       Registrants are  reminded that FIFRA section 6 (a) (2) states that if at any  time after a
pesticide is registered a registrant has additional factual information regarding unreasonable
adverse effects on the environment by the pesticide, the registrant shall submit the information
to the Agency.  Registrants must notify the Agency of any factual information they have, from
whatever source, including but not limited to interim or preliminary results of studies, regarding
unreasonable adverse effects on man or the environment. This requirement continues as long as
the products are registered by the Agency.

SPECIFIC INSTRUCTIONS FOR COMPLETING THE REQUIREMENTS STATUS AND
REGISTRANTS RESPONSE FORM

Generic Data

This form is  designed  to  be  used for registrants  to  respond to call-in-  for  generic and
product-specific data as part of EPA's reregistration program under the Federal Insecticide
Fungicide and Rodenticide  Act.  Although the form  is the same for both product specific and
generic data, instructions for completing the forms  differ slightly.   Specifically,  options for
satisfying product specific data requirements do not include (1) deletion or uses or (2) request for
a low  volume/minor  use waiver.   These  instructions  are for completion of generic data
requirements.

EPA has developed this form individually for each data call-in addressed to each registrant, and
has preprinted this form with a number of items.  DO NOT use this form for any other active
ingredient.

Items 1 through 8 (inclusive)  will have been preprinted on the form. You must complete all other
items on this form by typing or printing legibly.

Public reporting burden for this  collection of information is estimated to average  30 minutes per
response, including time for reviewing instructions, searching existing data sources, gathering and
maintaining the data needed, and completing and reviewing the collection of information.  Send
comments regarding the burden estimate or  any other aspect of this collection of information,
including suggesting for reducing this  burden, to Chief, Information Policy Branch, PM-223,

     ISSUED BY THE AGENCY	

     Unless otherwise noted herein, this Data Call-in does not in any way supersede or change
the requirements of any previous Data Call-in(s), or any other agreements entered into with the
Agency pertaining to such prior Notice.  Registrants must comply with the requirements of all
Notices to avoid issuance of a Notice of Intent to Suspend their affected products.

SECTION III. COMPLIANCE WITH REQUIREMENTS OF THIS NOTICE

III-A.  SCHEDULE FOR RESPONDING TO THE AGENCY

        The appropriate responses initially required by this Notice for product specific data must
be submitted to the Agency within 90 days after your receipt of this Notice. Failure to
adequately respond to this Notice  within 90 days of your receipt will be a basis for issuing a
Notice of Intent to Suspend (NOIS)  affecting your products. This and other bases for issuance of
NOIS due to failure to comply with this  Notice are presented in Section IV-A and IV-B.

III-B.  OPTIONS FOR  RESPONDING TO THE AGENCY

       The options for responding to this Notice for product specific data are: (a) voluntary
cancellation, (b) agree to satisfy the product specific data requirements imposed by this notice or
(c) request a data waiver (s).

       A discussion  of how to respond if you chose the Voluntary Cancellation option is
presented below.  A discussion of the various options available for satisfying the product specific
data requirements of this Notice is contained in Section III-C.  A discussion of options relating to
requests for data waivers is contained in Section III-D.

       There are two forms that accompany this Notice of which, depending upon your response,
one or both must be  used in your response to  the Agency.  These forms are the Data-Call-in
Response Form and the Requirements Status and Registrant's  Response Form, Attachment 2  and
Attachment 3. The Data Call-in Response Form must be submitted as part of every response to
this Notice.  In addition, one copy or the Requirements Status  and Registrant's Response Form
must be submitted for each product  listed on the Data Call-In Response Form unless the
voluntary cancellation option is selected  or unless the product is identical to another (refer to the
instructions for completing the Data Call-In Response Form in Attachment 2).  Please note that
the company's authorized representative is required to sign the first page of the Data Call-In
Response Form and Requirements Status and  Registrant's Response Form (if this form is
required) and initial any subsequent pages. The forms contain separate detailed instructions on the
response options.  Do not alter the printed material.  If you have questions or need assistance  in
preparing your response, call or write the contact person (s) identified in Attachment 1.

       1. Voluntary  Cancellation  - You  may avoid the requirements of this Notice by requesting
voluntary cancellation of your product(s) containing the active  ingredient that is the subject of this
Notice. If you wish to voluntarily cancel your product, you must submit a completed Data Call-
In Response  Form, indicating your election of this option. Voluntary cancellation is item number
b on the Data Calf-In Response Form. If you  choose this option, this is the only form that you
are required  to complete.

       If you chose to voluntarily cancel your product, further sale and distribution of your
product after the effective date of cancellation must be in accordance with the Existing Stocks
provisions of this Notice which are  contained in Section IV-C.

-------
       2. Satisfying the Product Specific Data Requirements of this Notice  There are various
options available to satisly the product specific data requirements of this Notice.  These options
are discussed in Section III-C of this Notice and comprise options 1 through 6 on the
Requirements Status and Registrant's Response Form and item numbers 7a  and 7b on the Data
Call-In Response Form. Deletion of a use(s) and the low volume/minor use option are not valid
options lor fulfilling product specific data requirements.

       3. Request for Product Specific Data Waivers.  Waivers for product specific data are
discussed in Section 111-D ol this Notice and are covered by option 7 on the Requirements Status
and Registrant's Response Form.  If you choose one of these options, you must submit both
forms as well as any other information/data pertaining to the option chosen  to address the data
requirement.

III-C  SATISFYING THE DATA REQUIREMENTS OF THIS NOTICE

       If you acknowledge on the Data Call-In Response Form that you agree to satisfy the
product specific data requirements (i.e. you select item number 7a  or 7b), then you must select
one of the six options on the Requirements Status and Registrant's  Response Form related to data
production for each data requirement. Your option selection should be entered under item
number 9,  "Registrant Response."  The six options  related to data production are the first six
options discussed under item 9 in the instructions for completing the Requirements Status and
Registrant's Response Form.  These six options  are listed immediately below with information in
parentheses to guide registrants to additional instructions provided  in this Section.  The options
are:

        1)     I will generate and submit data within the specified time frame (Developing Data)
        2)     I have entered into an agreement with one or more registrants to develop data
             jointly (Cost Sharing)
              I have made offers to cost-share (Offers to Cost Share)
              I am submitting  an existing study  that has not been submitted previously to the
              Agency by anyone (Submitting an Existing Study)
       (5)     I am submitting  or citing data to upgrade a study classified by EPA as partially
              acceptable and upgradeable  (Upgrading a Study)
       (6)     I am citing an existing study that EPA has classified  as acceptable or an existing
              study that has been submitted but  not reviewed by the Agency (Citing an Existing
              Study)

       Option 1  Developing Data — If you choose to develop the required data it must be in
conformance with Agency deadlines and with other Agency requirements as referenced herein
and in the attachments. All data generated and submitted must comply with the Good Laboratory
Practice (GLP) rule (40 CFR Part 160), be conducted according to the Pesticide Assessment
Guidelines (PAG), and be  in conformance  with the requirements of PR Notice 86-5.

       The time frames in the Requirements Status  and Registrant's Response Form are the time
frames that the Agency is allowing for the  submission of completed study reports. The noted
deadlines run from the  date of the receipt of this Notice by the registrant. If the data are not
submitted by the deadline, each registrant is subject to receipt of a  Notice of Intent to Suspend the
affected registration(s).

       If you cannot submit the data/reports to the Agency in the time required by this Notice
and intend to seek additional time to meet the requirements(s),  you must submit a request to the
Agency which includes: (1)  a detailed description of the expected difficulty and (2) a proposed
schedule including alternative dates for meeting such requirements  on a step-by-step basis.  You
must explain any technical or laboratory difficulties and provide documentation from the

                                           140

-------
laboratory performing the testing.  While EPA is considering your request, the original deadline
remains. The Agency will respond to your request in writing.  If EPA does not grant your
request, the original deadline remains.  Normally, extensions can be requested only in cases of
extraordinary testing problems beyond the expectation or control of the registrant. Extensions
will not be given in submitting the 90-day responses. Extensions will not be considered if the
request for extension is not made in a timely fashion; in no event shall an extension request be
considered if it is submitted at or after the lapse of the subject deadline.

       Option 2, Agreement to Share in Cost to Develop Data  — Registrants may only choose
this option for acute toxicity data and certain efficacy data and only if EPA has indicated in the
attached data tables that your product and at least one other product are similar for purposes of
depending on the same data.  If this is the case, data may be  generated for just one of the
products in the group.  The registration number of the product for which data will be submitted
must be noted in the agreement to cost share by the registrant selecting this option.  If you choose
to enter into an agreement to share in the cost of producing the required  data but will not be
submitting the data yourself, you must provide the name of the registrant who will be submitting
the data.  You must also provide EPA with documentary evidence that an agreement has been
formed. Such evidence may be your letter offering to join in an agreement and the other
registrant's acceptance of your offer, or a written statement by the parties that an agreement
exists. The agreement to produce the data need not specify all of the terms of the final
arrangement between the parties or the mechanism to resolve the terms.  Section 3(c)(2)(B)
provides that if the parties cannot resolve the terms of the agreement they may resolve  their
differences through binding arbitration.

       Option 3, Offer to Share in the Cost of Data Development — This option only applies to
acute  toxicity and certain efficacy data as described in option 2 above. If you have made an offer
to pay in an attempt to enter into an agreement or amend an existing agreement to meet the
requirements of this Notice and have  been unsuccessful, you  may request EPA  (by selecting this
option) to  exercise its discretion not to suspend your registration^), although you do not comply
with the data submission requirements of this Notice. EPA has determined that as a general
policy, absent other relevant considerations, it will not suspend the registration  of a product  of a
registrant who has in good faith sought and continues to seek to enter into a joint data
development/cost sharing program, but the other registrant(s) developing the data has refused to
accept your offer.  To qualify for this option, you must submit documentation to the Agency
proving that you have made an offer  to another registrant (who has an obligation to submit data)
to share in the burden of developing that data.  You must also submit to the Agency  a completed
EPA Form 8570-32,  Certification of  Offer to Cost Share in the Development of Data,
Attachment 7.  In addition, you must demonstrate that the other registrant to whom the offer was
made  has not accepted your offer to enter into a cost sharing  agreement by including a  copy  of
your offer and proof of the other registrant's receipt of that offer (such as a certified mail
receipt).  Your offer must, in addition to anything else, offer to share in  the burden of  producing
the data upon terms to be agreed or failing agreement to be bound by binding arbitration as
provided by FIFRA section 3(c) (2) (B) (iii) and must not qualify this offer.  The other registrant
must also  inform EPA of its election  of an option to  develop  and submit  the data required by this
Notice by  submitting a Data Call-In Response Form and a Requirements  Status and Registrant's
Response Form committing to develop and submit the data required by this Notice.

       In order for you to avoid suspension under this option, you may not withdraw your offer
to share in the burdens of developing the data. In addition, the other registrant must fulfill its
commitment to develop and submit the data as required by this Notice. If the other registrant
fails to develop the data or for some  other reason is 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 do submit the required data in the specified time
frame. In such cases, the Agency generally will not grant a time extension for submitting the
data.
                                            141

-------
       Option 4, Submitting an Existing Study — If you choose to submit an existing study in
response to this Notice, you must determine that the study satisfies the requirements imposed by
this Notice.  You may only submit a study that has not been previously submitted to the Agency
or previously cited by anyone.  Existing studies are studies which predate issuance of this Notice.
Do not use this option if you are submitting data to upgrade a study. (See Option 5).

       You should be aware that if the Agency determines that the study is not acceptable,  the
Agency will require you to comply with this Notice, normally without an extension of the
required date of submission.  The Agency may determine at any time that a study is not valid and
needs to be repeated.

       To meet the requirements of the DCI Notice for submitting an existing study, all of the
following three criteria must be clearly met:

       a.     You must certify at the time that the existing study is submitted that the raw  data
              and specimens  from the study are available for audit and review and you must
              identify where  they are available.  This must be done in accordance with the
              requirements of the  Good Laboratory Practice (GLP) regulation, 40 CFR Part
              160. As stated  in 40 CFR 160.3(j) " 'raw data' means any laboratory worksheets,
              records, memoranda, notes, or exact copies thereof, that are the result of original
              observations and activities of a study and are necessary for the reconstruction and
              evaluation of the report of that study.  In the event that exact transcripts of raw
              data have been prepared (e.g.,  tapes which have been transcribed verbatim, dated,
              and verified accurate by signature), the exact copy or exact transcript may be
              substituted for  the original source as raw data.  Raw data'  may include
              photographs, microfilm or microfiche copies,  computer printouts, magnetic media,
              including dictated observations, and recorded data from automated instruments."
              The term "specimens", according to 40 CFR 160.3(k), means "any material
              derived from a test system for examination or  analysis."

       b.     Health and safety studies completed after May 1984 must also contain all GLP-
              required quality assurance and quality control  information,  pursuant to the
              requirements of 40 CFR Part 160.  Registrants must also certify at the time of
              submitting the  existing study that such GLP information is available for post-May
              1984 studies by including an appropriate  statement on or attached to the study
              signed by an authorized official or representative of the registrant.

       c.     You must certify that each study fulfills the acceptance criteria for the Guideline
              relevant to the  study provided in the FIFRA Accelerated Reregistration Phase 3
              Technical Guidance and that the study has been conducted according to the
              Pesticide Assessment Guidelines (PAG) or  meets the purpose of the PAG (both
              available from  NTIS).  A study not conducted according to the PAG may be
              submitted to the Agency for consideration if the registrant believes that the study
              clearly meets the purpose of the PAG. The registrant is referred to 40 CFR
              158.70 which states the Agency's policy  regarding acceptable protocols. If you
              wish to submit the study, you  must, in addition to certifying that the purposes of
              the PAG are met by the study,  clearly articulate the rationale why you believe the
              study meets the purpose of the  PAG, including copies of any supporting
              information or  data.  It has been the Agency's experience that studies completed
              prior to January 1970 rarely satisfied the purpose of the PAG and that necessary
              raw data are usually not available for such studies.


       If you submit an existing study, you must certify that the study meets all requirements of
the criteria outlined above.
                                            142

-------
       If you know of a study pertaining to any requirement in this Notice which does not meet
the criteria outlined above but does contain factual information regarding unreasonable adverse
effects, you must notify the Agency of such a study. If such  study is in the Agency's files, you
need only cite it along with the notification. If not in the Agency's files, you must submit a
summary and copies as required by PR Notice 86-5.

       Option 5, Upgrading a Study — If a study has been classified as partially acceptable and
upgradeable, you may submit data to  upgrade that study. The Agency will review the data
submitted and determine if the requirement is satisfied.  If the Agency decides the requirement is
not satisfied, you may still be required to submit new data normally without any time extension.
Deficient, but upgradeable studies will normally be classified as supplemental. However, it is
important to note that not all studies classified as supplemental are upgradeable. If you have
questions regarding the classification  of a study or whether a study may be upgraded, call or
write the contact person listed in Attachment  1.  If you submit data to upgrade an existing study
you must satisfy or supply information to correct all deficiencies in the study identified by EPA.
You must provide a clearly articulated rationale of~how the deficiencies have been remedied or
corrected and why the study should be rated as acceptable to EPA. Your submission must also
specify the MRID number (s) of the study which you are attempting to upgrade and must be in
conformance with PR Notice 86-5.

       Do not submit additional data  for the purpose of upgrading a study classified  as
unacceptable and determined by the Agency as not capable of being upgraded.

       This option should also be used to cite data that has been previously submitted to  upgrade
a study, but has not yet been reviewed by the Agency.  You must provide the MRID number of
the data submission as well as the MRID number of the study being upgraded.

       The criteria for submitting an  existing study, as specified in Option 4 above,  apply to all
data submissions intended to upgrade  studies.  Additionally your submission of data  intended to
upgrade studies must be accompanied by a  certification that you comply with each of those
criteria as well as a certification regarding protocol compliance with Agency requirements.

       Option 6, Citing Existing Studies — If you choose to cite a study that has been previously
submitted to EPA,  that study must have been previously classified by EPA as acceptable or it
must be a study which has not yet been reviewed  by the Agency.  Acceptable  toxicology studies
generally will have been classified as  "core-guideline" or ' core minimum." For all  other
disciplines the classification would be "acceptable." With respect to any studies for  which you
wish to select this option you must provide the MRID number of the study you are citing and, if
the study has been  reviewed by the Agency, you must provide the Agency's classification of the
study.

       If you are citing  a study of which you are  not the original data submitter, you must submit
a completed copy of EPA Form 8570-31, Certification with Respect to Data Compensation
Requirements.

       Registrants  who select one of  the above 6 options must meet all of the  requirements
described  in the instructions for completing the Data Call-in Response Form and the
Requirements Status and Registrant's  Response Form, as appropriate.

III-D  REQUESTS FOR DATA WAIVERS

             If you request a waiver for product specific data because you believe it is
inappropriate, you must attach a complete Justification for the request, including technical
reasons, data and references to relevant EPA regulations, guidelines or policies.  (Note:  any
supplemental data must be submitted  in the format required by PR Notice 86-5).  This will be the
only opportunity to state the reasons or provide information in support  of your request.  If the

                                            143

-------
Agency approves your waiver request, you will not be required to supply the data pursuant to
section 3(c)(2)(B) of FIFRA.  If the Agency denies your waiver request, you must choose an
option for meeting the data requirements of this Notice within 30 days of the receipt of the
Agency's decision.  You must indicate and submit the option chosen on the Requirements Status
and Registrant's Response Form.  Product specific data requirements for product chemistry,
acute toxicity and efficacy (where appropriate) are required for all products  and the Agency
would grant a waiver only under  extraordinary circumstances.  You should also be aware that
submitting a waiver request will not automatically extend the due date for the study in question.
Waiver requests submitted
without adequate supporting rationale will be denied and the original due date will  remain in
force.

IV.  CONSEQUENCES OF FAILURE TO COMPLY WITH THIS NOTICE

IV-A NOTICE OF INTENT TO SUSPEND

       The Agency  may issue a Notice of Intent to Suspend products subject to this Notice due to
failure by a registrant to comply with the requirements of this Data Call-in Notice, pursuant to
FIFRA section 3(c) (2) (B). Events which may be  the basis for issuance of a  Notice of Intent to
Suspend include, but are not limited to, the following:

       1.     Failure to respond as required by this Notice within 90 days of your receipt of this
             Notice.

       2.     Failure to submit on the required schedule an acceptable proposed or final protocol
             when such is required to be submitted to the Agency for review.

       3.     Failure to submit on the required schedule an adequate progress report on a study
             as required by this Notice.

       4.     Failure to submit on the required schedule acceptable data as  required by this
             Notice.

       5.     Failure to take a required action or submit adequate information pertaining to any
             option chosen to address the data requirements  (e.g., any required action or
             information pertaining to submission or citation of existing studies or offers,
             arrangements, or arbitration on the sharing of costs or  the formation of Task
             Forces, failure to comply with the terms of an agreement or arbitration concerning
             joint data development or failure to comply with any terms of a data waiver).

       6.     Failure to submit supportable certifications as to the conditions of submitted
             studies, as required by Section III-C of this Notice.

       7.     Withdrawal of an offer to share in the cost of developing required data.

       8.     Failure of the registrant to whom you have tendered an offer  to share in the cost of
             developing data and provided proof of the registrant's receipt of such offer or
             failure of a registrant on whom you rely for a generic data exemption either to:

             a.     inform EPA of intent to develop and submit the data required by this
                    Notice on a Data Call-In Response Form and a  Requirements Status and
                    Registrant's Response Form;

             b.     fulfill the commitment to develop and submit the data  as required by this
                    Notice; or
                                           144

-------
              c.     otherwise take appropriate steps to meet the requirements stated in this
                    Notice, unless you commit to submit and do submit the required data in the
                    specified time frame.

       9.      Failure to take any required or appropriate steps, not mentioned above, at any time
              following the issuance of this Notice.

IV-B.  BASIS FOR DETERMINATION THAT SUBMITTED STUDY IS
UNACCEP TABLE

       The Agency may determine that a study (even if submitted within the required time)  is
unacceptable and constitutes  a basis for issuance of a Notice of Intent to Suspend. The grounds
for suspension include, but are not limited to,  failure to meet any of the following:

       1.  EPA requirements specified in the Data Call-In Notice or other documents
       incorporated by reference (including, as applicable, EPA Pesticide  Assessment
       Guidelines, Data Reporting Guidelines, and GeneTox Health Effects Test Guidelines)
       regarding the design, conduct,  and reporting of required studies. Such requirements
       include, but are not limited  to,  those relating to test material, test procedures, selection of
       species, number of animals, sex and distribution of animals,  dose and effect levels to be
       tested or attained, duration of test, and, as applicable, Good  Laboratory Practices.

       2.  EPA requirements regarding the submission of protocols, including the incorporation
       of any changes required by  the Agency following review.

       3.  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 86-5. All studies must be submitted in the form of a final report; a
       preliminary report will not be considered to fulfill the submission requirement.

IV-C EXISTING STOCKS  OF SUSPENDED OR CANCELLED PRODUCTS

       EPA has statutory authority to  permit continued sale, distribution and use of existing
stocks of a pesticide product which has been suspended or cancelled if doing so would be
consistent with the purposes  of the  Act.

       The Agency has determined that such disposition  by registrants  of existing stocks for a
suspended registration when a section  3 (c) (2) (B) data request is outstanding would generally not
be consistent with the Act's purposes.  Accordingly, the  Agency anticipates granting registrants
permission to sell, distribute, or use existing stocks of suspended product(s) only in exceptional
circumstances.  If you believe such disposition of existing stocks of  your product(s) which may
be suspended for failure to comply with this Notice should be permitted, you have the burden of
clearly demonstrating to EPA that granting such permission would be consistent with the Act.
You must also explain 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, distribution,
and use. Unless you meet this burden the Agency will not consider  any request pertaining to the
continued sale, distribution, or use of your existing stocks after suspension.

       If you request a voluntary cancellation  of your product(s) as  a response to this Notice and
your product is in full compliance with all Agency requirements, you will  have, under most
circumstances, one year from the date your 90 day response to this Notice is due, to sell,
distribute, or use existing stocks.  Normally, the Agency will allow  persons other than the
registrant such as independent distributors, retailers and end users to sell, distribute or use such
existing stocks until the stocks are exhausted.  Any sale,  distribution or use of stocks of
voluntarily cancelled products containing an active ingredient for which the Agency has particular

                                           145

-------
risk concerns will be determined on case-by-case basis.

       Requests for voluntary cancellation received after the 90 day response period required by
this Notice will not result in the Agency granting any additional time to sell, distribute,  or use
existing stocks beyond a year from the date the 90 day response was due unless you demonstrate
to the Agency that you are in full compliance with all Agency requirements, including the
requirements of this Notice.  For example,  if you decide to voluntarily cancel your registration
six months before a 3 year study is scheduled to be submitted, all progress reports and other
information necessary to establish that you have been conducting the study in an acceptable and
good faith manner must have been submitted to the Agency, before EPA will consider granting
an existing stocks provision.

SECTION V.  REGISTRANTS' OBLIGATION TO REPORT POSSIBLE
UNREASONABLE ADVERSE EFFECTS

       Registrants are reminded that FIFRA section 6 (a) (2)  states that if at any time after a
pesticide is registered a registrant has additional factual information regarding unreasonable
adverse effects on the environment by the pesticide, the registrant shall submit the information to
the Agency.   Registrants must notify the Agency of any factual information they have, from
whatever source, including but not limited to interim or preliminary results of studies, regarding
unreasonable adverse effects on man or the environment.  This requirement continues as long as
the products are registered by the Agency.

SECTION VI. INQUIRIES AND RESPONSES TO THIS NOTICE

       If you have any questions regarding the requirements and procedures established by this
Notice, call the contact person(s) listed in Attachment  1, the Data Call-In Chemical Status Sheet.

                 Fosamine  ammonium
     Pesticide
Reregistration
   Use Profile
     All pesticides sold or distributed in the United States must be
registered by EPA, based on scientific studies showing that they can be used
without posing unreasonable risks to people or the environment.  Because of
advances in scientific knowledge, the law requires that pesticides which
were first registered years ago be reregistered to ensure that they meet
today's more stringent standards.
     In evaluating pesticides for reregistration, EPA obtains and reviews a
complete set of studies from pesticide producers,  describing the human
health and environmental effects of each pesticide. The Agency imposes
any regulatory controls that are needed to effectively manage each
pesticide's risks.  EPA then reregisters pesticides that can be used without
posing unreasonable risks to human health or the environment.
     When a pesticide is eligible for reregistration, EPA announces this and
explains why in a Reregistration Eligibility Decision (RED) document. This
fact sheet summarizes the information in the RED document for
reregistration case 2355, fosamine ammonium.

     Fosamine ammonium is an herbicide/plant growth regulator used to
control brush and herbaceous plants on noncropland.  It is applied to
nonagricultural rights-of-way (e.g. highways, railroads, and utilities),
industrial sites, and fencerows.
     Fosamine ammonium is formulated in end use products as a water
soluble liquid. It is applied once per year from Spring to early Fall, by
aircraft, backpack and handwands.  After application, the brush control
effects of the pesticide are achieved by inhibiting bud growth the following
year.
     Use practice limitations prohibit fosamine ammonium from being used
on croplands or in irrigation systems. It may not be applied directly to
water, or areas where surface water is present, including intertidal areas.
Soils treated with this herbicide cannot be converted to food/feed croplands
within one year of treatment.
     Fosamine ammonium is not registered for use in California and
Arizona.
   Regulatory
     Fosamine ammonium was first registered as a pesticide in the U.S. in

-------
        History
Human Health
  Assessment
1975.  It was registered for non-cropland (non-food use) areas such as
railroads, pipelines, utility and highway rights-of way, reforestation areas,
drainage ditch banks, storage areas, industrial plants, and other similar sites.
However, this product was voluntarily cancelled on June 22, 1994.
     A second product was registered in 1980 with the same uses as the
original product except for reforestation uses. This product currently is
marketed under two trade names.  The registrant requested to voluntarily
cancel  direct  applications to water, ditch banks, and to other sites which are
adjacent to and  surrounding domestic water supply reservoirs, supply
streams, lakes and ponds.  The Agency is processing this request, which
involves publishing a Notice of Intent to  delete these uses in the Federal
Register.  Because there are no other current registrants and there are
outstanding environmental data requirements to support continued
registration of these uses, the Agency expects that these sites will be deleted
from the label by  early 1995.

Toxicity
     Fosamine ammonium is classified as Toxicity Category II for acute
dermal studies in  mammalian species. This classification represents the
second most severe level of acute toxicity for studies using laboratory
animals (Toxicity  Category I is the highest). Fosamine ammonium is very
mildly  toxic for acute oral and acute inhalation  (Toxicity Category IV), and
is not a dermal  sensitizer.
     In one subchronic oral study, the laboratory animals given the highest
dose of fosamine ammonium exhibited some statistically significant effects,
including effects to the kidneys, bladder and decreases in body weight.
There were no subchronic neurotoxic effects of fosamine ammonium  at any
dose level.
     Fosamine ammonium displayed some mutagenic potential in one in
vitro test for chromosome aberrations,  while four other tests were negative
for mutagenic potential.
Dietary Exposure
     Since there  are no registered food uses for fosamine ammonium, no
dietary exposure is expected.
Occupational and Residential Exposure
     Based on  current use patterns,  workers may be exposed to fosamine
ammonium during and after application of the pesticide.  Worker exposure
estimates are  based on the assumption that workers wear long pants, long
sleeved shirt,  shoes, and no gloves, except for workers using backpacks
(who are assumed to wear chemical resistant gloves).  The primary route of
exposure to fosamine ammonium is expected to be dermal.  Another
potential route of  exposure is through inhalation.  However,  based on the
exposure assumptions, the potential for inhalation exposure is negligible.
Human Risk Assessment

-------
Environmental
  Assessment
     Since no food uses are registered, fosamine ammonium poses no
human dietary risks. Regarding acute toxicity, fosamine ammonium falls in
Toxicity Category II for acute dermal exposure.  However, the mild skin
effects observed with this chemical do not trigger any significant
toxicological concerns. The herbicide/plant growth regulator is of low
toxicity by the oral and inhalation routes.  Based on the mixed results of
studies suggesting mutagenetic potential, the Agency is requiring additional
testing with germ cells as a confirmatory study.
     Based on the current use pattern of fosamine ammonium, the
estimated exposure to workers, which is likely to reflect a worse-case
scenario, does not pose a serious threat to workers.  However, there are no
known significant acute or chronic toxicological endpoints that warrant the
establishment of risk mitigation measures or minimum personal protective
equipment (PPE) requirements to protect handlers of the pesticide. Clothing
as described in the exposure assessment will provide adequate protection to
handlers. In addition, EPA is requiring application restrictions and user
safety recommendations on end-use product labeling.

Environmental Fate
     Fosamine ammonium is not very persistent under aerobic or anaerobic
conditions and degrades rapidly in most soils. Dissipation of fosamine
ammonium is dependent on rapid, microbial mediated degradation.  Thus,
in field studies  fosamine ammonium was found to be highly soluble in water
and is mobile in various soils.  However, in the sterile conditions of the
laboratory, fosamine ammonium is stable to hydrolysis. Although fosamine
ammonium is a mobile compound, there is little evidence that leaching is a
major route of dissipation.   Data on the residues of fosamine ammonium
indicate they are also relatively mobile.
     Fosamine ammonium may be found in surface waters with low
microbiological activities or long hydrological residence times.
     Exposure of fosamine ammonium to non-target aquatic plants can
result from spray drift from treated areas, surface runoff, or wind blown
soil particles.  However, no acute risk quotients exceed the level of concern,
so no acute effects to aquatic plants are  expected from the normal use  of
fosamine ammonium.
     The risk to terrestrial non-target plants  cannot be determined until
Tier I and Tier II data requirements have been fulfilled. Results of the most
sensitive terrestrial plant species tested  are needed in order to conduct an
acute risk assessment.
     Any movement of fosamine ammonium from the treatment site via
spray drift, surface runoff, or wind blown soil particles can adversely  affect
non-target and endangered/threatened plants.  Direct application of rights-
of-way are a special concern, because large numbers of endangered plants
grow in rights-of-way areas.  Thus applications of fosamine ammonium at

-------
the registered rates may pose a significant risk to endangered plant species
inhabiting treated rights-of-way.
     EPA has been working with the U.S. Fish and Wildlife Service and
other federal and state agencies to develop a program to avoid jeopardizing
endangered species. The Endangered Species Program is expected to be
final soon.  Further limitations on the use of fosamine ammonium may be
imposed at that time.
     Further droplet size spectrum and field drift studies are due to the
Agency at the end of June 1995 as part of the spray drift data requirements
to be submitted by the Spray Drift Task Force.  If the new data suggest
substantially different drift potential, the Agency will reassess its impact on
the associated environmental risks at that time.
Ecological Effects
     Exposure to non-target aquatic organisms can result from spray drift
and runoff from treated areas.  However, acute effects to freshwater fish
and aquatic invertebrates are not  expected from the normal use of fosamine
ammonium.  Fosamine ammonium is practically nontoxic to coldwater and
warmwater fish, and does not appear to bioaccumulate in fish.  However, a
nine percent fish mortality was observed in the accumulation in fish study.
Fosamine ammonium is practically nontoxic to freshwater invertebrates and
to estuarine species.
     Fosamine ammonium is practically nontoxic to honey bees, which are
used to assess the effects  on non-target insects.
     Fosamine ammonium is practically nontoxic to avian species on an
acute oral and a subacute dietary basis.  Mixed results were found in the
avian reproductive studies.  In one mallard duck study,  there was some
indication of chronic reproductive effects. However, in  another avian
reproductive study, using the bob white quail as the test organism, there
were no reproductive effects at any dose level.
     Fosamine ammonium is practically nontoxic to small mammalian
species. Acute oral and subacute dietary risks to non-endangered and
endangered non-target mammals  are not expected to result from current
label uses.
Ecological Effects Risk Assessment
     Based on the data, fosamine ammonium dissipation is predominantly
dependent on rapid microbial-mediated degradation. It is also mobile in
mineral soils.  However, fosamine ammonium should not pose a threat to
groundwater or surface waters because it rapidly degrades in aerobic and
anaerobic environments.  There are no Maximum Concentration Levels

Changes Required
(MCLs) or drinking water health advisories for fosamine ammonium or its
degradates.
     The health and environmental data on fosamine ammonium indicate a
low level of toxicity of this pesticide. However, the inconclusive results in
the avian reproductive studies have led the Agency to require a new mallard
duck reproduction study on a confirmatory basis.  In addition, risk
mitigation measures are required to reduce the potential for avian
reproductive effects.
     EPA is requiring the following additional generic data for fosamine
ammonium to confirm its regulatory assessments  and conclusions:
Certification of limits (62-2), Avian reproduction, mallards (71-4b), In-vivo
cytogenetics (84-2a), Droplet size spectrum and field drift data (201-1, 202-
1), Method validation for worker exposure (231,  232), Terrestrial plant
(122-1, 123-1), and Aerobic aquatic (164-2, 162-4) if aquatic sites are not
deleted.
     The Agency also is requiring product-specific data including product
chemistry and acute toxicity studies, revised Confidential Statements of
Formula (CSFs) and revised labeling for reregistration.

     All fosamine ammonium end-use products must comply with EPA's
current pesticide product labeling requirements, and with the following:
a)  Within the Environmental Hazards section of the Precautionary Statement
of the label:
     "Do not apply directly to water,  or to areas where surface water is
     present or to intertidal areas below the mean high water mark.  Do not
     contaminate water when disposing of equipment washwaters or
     rinsate."
b)  To reduce environmental loading and potential exposure to non-target
species, the product label must include language to limit use as outlined
below:
     i) the end-use product can be applied only once annually during the
     period after spring growth has hardened to  the development of fall
     coloration in deciduous species, and
     ii) the maximum application rate for low shrubs/brush is  16  Ib a.i./A,
     and for tall  dense woody species with very  heavy foliage can be  24 Ib
     a.i./A.
c)  The end-use  product labels cannot include directions for applications to
aquatic sites.  The current,  sole registrant has submitted an application for
amended registration to delete these uses from its product registration.
Future submissions of appropriate data to support registration for these uses
will be considered by the Agency.
d)  The Agency  is requiring the following labelling statements to be located
on all end-use products containing fosamine ammonium:
     Application Restrictions:

 Regulatory
Conclusion
   For More
Information
           "Do not apply this product in a way that will contact workers or
           other persons, either directly or through drift.  Only protected
           handlers may be in the area during applications."
     Entry Restrictions
           The Agency is establishing the following entry restrictions for
           the occupational uses of fosamine  ammonium end-use products:
           For liquid applications:
           "Do not enter or allow others to enter the treated area until
           sprays have dried."
Other Labelling Requirements:
     User Safety Recommendations:
           "Users should wash hands before eating, drinking, chewing
           gum, using tobacco, or using the toilet."
           "Users should remove clothing immediately if pesticide gets
           inside.  Then wash thoroughly and put on clean clothing."
           "Users should remove clothing immediately after handling this
           product.  If gloves are worn, wash the outside of gloves before
           removing.  As soon as possible, wash thoroughly and change
           into clean clothing."
     These statements must be  included on the labels, as they are
appropriate, after product-specific PPE requirements are set by the Agency.
Although it is not required under the  current labeling, it is  assumed that the
workers wear long pants, long sleeved shirts, shoes, and socks.

     The use of currently registered  products containing fosamine
ammonium in accordance with approved labeling, except use in aquatic
sites, will not pose unreasonable risks or adverse  effects to  humans or the
environment. The registrant has voluntarily requested cancellation of the
aquatic uses.  The Agency is not including the aquatic uses  in its eligibility
decision, because of the inadequate environmental data and the impending
deletion of those uses from all current registrations.  Therefore, all uses of
fosamine ammonium products, other  than application to aquatic sites, are
considered eligible for re registration.
     Fosamine ammonium products will be reregistered once the required,
product-specific data, revised Confidential Statements of Formula,  and
revised labeling are received and accepted by EPA.
