CERTIFIED MAIL
Dear Registrant:

       I am pleased to announce that the Environmental Protection Agency has completed its
reregi strati on eligibility review and decisions on the pesticide active ingredient dimethoxane.
The enclosed Reregistration Eligibility Decision (RED) contains the Agency's evaluation of
the data base of these chemicals, 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 reregi strati on. The RED includes the data and
labeling requirements for products for reregi strati on. 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.

             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
reregi strati on, 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 REOUESTS-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 reregi strati on) separately. You  may
delete uses which the RED says are ineligible for reregi strati on.  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

       Based on the reviews of the generic data for the active ingredient dimethoxane (2,6-
Dimethyl-m-dioxan-4-ol acetate),  the  Environmental Protection  Agency  has  sufficient
information on the health effects of dimethoxane and on its potential for causing adverse effects
in fish and wildlife in the  environment.  The Agency has determined that the dimethoxane
product, labeled and used as specified in this Reregi strati on Eligibility Decision, will not pose
unreasonable risks or adverse effects to humans or the environment.  Therefore, the Agency
concludes that all uses of the product containing dimethoxane are eligible for reregi strati on.

       Dimethoxane (Giv-Gard DXN) is a fungicide, microbiocide/microbiostat formulated as
a liquid soluble concentrate.  As an industrial preservative/antimicrobial agent, Giv-Gard DXN,
the only product containing dimethoxane  currently registered, is used  in the preservation of
numerous types of emulsions and water-based industrial processes and is not used on or in
finished  products.  This biocidal product offers  protection  against microbial spoilage or
contamination  of another  product  during its manufacture or processing  (i.e.,  industrial
preservative).  It is used in the manufacturing process to control spoilage microorganisms
encountered in industrial emulsions and specialty industrial products, textiles, jet fuels, adhesives
and leather processing liquors.

       The toxicological data base for dimethoxane suggests a low toxicity to mammals on an
acute and subchronic basis.  Due to the low toxicity, neither short term (1  to 7  days)  nor
intermediate term (1 week to several months) toxicological endpoints for occupational risk
assessment were identified.  Also, dimethoxane is slightly toxic to practically nontoxic to avian
species on an acute oral and subacute dietary basis, and not more than slightly toxic to freshwater
fish and invertebrates.

       Before reregistering the product  containing  dimethoxane, 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 the product.

I.      INTRODUCTION

       In 1988, the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA) was amended
to accelerate the reregi strati on of products with active ingredients registered prior to November
1, 1984. The amended Act provides a schedule for the reregi strati on process which is comprised
of five phases. The first four phases of the process focus on identification of data requirements
to support the reregi strati on 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 reregi strati on.

       FIFRA  Section 4(g)(2)(A) states that  in Phase  5 "the Administrator shall determine
whether pesticides containing such active ingredient are eligible for reregi strati on" before calling
in  data on products and  either reregistering products or taking "other appropriate regulatory
action." Thus, reregi strati on 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 reregi strati on eligibility of
the registered uses of dimethoxane. The document consists of six sections. Section I is the
introduction. Section II  describes dimethoxane,  its uses,  data requirements and regulatory
history. Section III discusses the human health and environmental assessment based on the data

      B.     Use Profile

             The following is information on the currently registered uses with an overview of
      use sites and application methods.  A detailed table of these uses of dimethoxane is in
      Appendix A.

             For dimethoxane:

             Type of Pesticide: Microbiocide/Microbiostat (slime-forming bacteria and fungi),
      Bacteriostat, Fungicide

             Use Sites:

             INDOOR NON-FOOD:

-------
       The intent of this biocidal product is to offer protection against microbial
spoilage or contamination of another product during its manufacture or processing
(i.e. industrial preservative).  As an industrial  preservative/antimicrobial agent,
Giv-Gard DXN has been found to be important in the preservation of numerous
types of emulsions and water-based industrial  processes. These registered uses
include the following:

       1) Emulsions (latex, PVA (polyvinyl alcohol), silicone, oil,  acrylic,
         polyethylene, PVC (polyvinyl chloride), etc.).
       2) Paints (emulsion)
       3) Coatings, industrial, preservatives
       4) Specialty industrial products/preservatives  (e.g., pigment slurries,
         dyestuffs, inks, thickeners/gums, lignosulfonates)
       5) Textile chemicals and finishes (such as dye  levelers, textile auxiliaries,
         softeners, lubricants, antistats, sizings, print pastes, etc.)
       6) Adhesives, industrial/preservatives
       7) Leather processing liquors (e.g., wet processing leather finishes)
       9) Distillate fuels

PVA

       Giv-Gard DXN is added to PVA emulsions to protect these emulsions from
damage  caused by microbial organisms.  The emulsions in turn are used as
components in the manufacture of industrial adhesives.

Silicone

       Giv-Gard DXN is added to silicone emulsions to protect these emulsions
from damage caused by microbial organisms. The emulsions in turn are used in
either the manufacture of caulks, sealants, etc. for the construction industry or
incorporated into softeners, lubricants, etc., utilized by the textile industry during
the manufacture of fibers/yarns.

Thickeners/Gums

       Giv-Gard DXN is added to thickeners/gums to protect these materials from
damage  caused by microbial organisms.  These  materials are  used in the
production (i.e.,  manufacture) of carpets and fabrics  as dyeing  and printing
auxiliaries such as print pastes, pigment pastes, or adhesives.

-------
       Textile Auxiliaries

             Giv-Gard DXN is added to "auxiliaries" used in the production of textiles
       to protect these agents from  damage caused by microbial organisms.  These
       industrial  auxiliaries include dyestuffs,  softeners,  sizings,  print pastes and
       lubricants.

       Target Pests:        Spoilage microorganisms, gram positive and gram negative
                           bacteria, yeast, and fungi.
       Formulation Types Registered: Soluble concentrate/liquid; 87%


       Method and Rates of Application:

             Equipment -  Not specified

             Method and  Rate - For industrial preservative treatment of emulsions,
             paints,  coatings, specialty industrial products,  textile  chemicals and
             finishes, industrial adhesives and leather processing liquors - 870 ppm to
             1740 ppm active ingredient by weight.

             For preservative treatment of distillate fuels - 870 ppm to 1740 ppm active
             ingredient by weight.

             Timing - During manufacture, not specified

       Use Practice Limitations:

             Compatibility with systems containing amides or amines warrants careful
             examination because product may cause discoloration in such systems.

C.     Estimated Usage of Pesticide

       The only source available which can provide a quantitative estimate of usage of
dimethoxane is The Federal Insecticide, Fungicide, and Rodenticide Act as Amended,
Section 7 data, which is Confidential Business Information and cannot be published since
currently there is only one registrant. One source, Kline and Co. Inc., which addresses
specialty biocides, gives usage estimates only for major active ingredients or products.
Kline does not  provide a quantitative estimate of dimethoxane use or list it as a major
chemical  on any  site.  Kline  does state that  dimethoxane's greatest  usage is as a
preservative of aqueous emulsions used in the textile industry.

-------
      D  Regulatory History

             The first product containing dimethoxane, 2,6-Dimethyl-m-dioxan-4-ol acetate,
      as an active ingredient was registered in the United States in 1962. Currently, one product
      is registered for use. The 1987 antimicrobial Data Call-In (DCI) required the submission
      of a variety of subchronic and chronic toxicology and occupational exposure studies. The
      reregi strati on Phase IV DCI was issued in 1992.

       B.    Human Health Assessment

             1.     Toxicology Assessment

                   Adequate animal toxicological data on dimethoxane are available and will
             support reregistration eligibility as a non-food use pesticide. The data are reported
             below.

GAI. Ihese data are presented lor international purposes.
       An acute oral toxicity study in rats found the LD50 was greater than
2000 mg/kg which is  toxicity  category  III (guideline  81-1,  MRID
43528501). An acute dermal toxicity study with rats found the LD50 was
greater than 2000 mg/kg, which is toxicity category III (guideline 81-2,
MRID 42667701). In an acute inhalation study with rats, the LD50 was
greater than 4.0 mg/L,  which is toxicity category III (guideline 81-3,
MRID 41936702).

       In a primary eye irritation study, rabbits had mild transient ocular
irritation, which is toxicity category III (guideline 81-4, MRID 41641102).
In a primary dermal irritation study with rabbits, there was slight erythema,
with irritation clearing in all but one animal by 48 hours. This is toxicity
category IV (guideline 81-5; MRID 41641101).

       When a dermal sensitization study was conducted with guinea pigs,
dimethoxane was shown to be a strong sensitizer (guideline 81-6; MRID
41936703).

b.     Subchronic Toxicity

       Dimethoxane was administered dermally to Sprague Dawley rats
for three months. The doses were 0, 100, 300, or 1000 mg/kg/day. Some
dermal irritation was observed at the  dose site in the 1000 mg/kg/day
group. The two highest dose groups had, in males, reduced body weight
gains and in females, an increased incidence of hepatic changes, including
necrosis, inflammation, and hemorrhage. The NOEL was 100 mg/kg/day.
The  LOEL was 300 mg/kg/day, based on these effects (guideline 82-2;
MRID 42952201).

-------
c.      Carcinogenicity

       The   National   Toxicology   Program   (NTP)    conducted
carcinogenicity studies with commercial grade dimethoxane. With F344/N
rats, the males were given 0, 62.5, or 125 mg/kg/day and the females were
given 0, 125 or 250 mg/kg/day by gavage for two years. Acanthosis and
hyperkeratosis were increased in the forestomach of high dose rats. With
B6C3F1 mice, the males and females were given 0, 250, or 500 mg/kg/day
by gavage for two years. Acanthosis,  hyperkeratosis, focal hyperplasia,
and chronic inflammation  were increased in the forestomach of dosed
mice. With an increased incidence of squamous cell papillomas  of the
forestomach in high dose male mice, NTP concluded that there was
equivocal evidence of carcinogenicity for male mice. However, there was
no evidence of dimethoxane carcinogenicity in female mice or in male or
female rats. (NTP, 1989).

d.      Developmental Toxicity

       Sprague Dawley  rats were given doses of 0, 60,  300, or 900
mg/kg/day of dimethoxane by gavage on gestation days 6-15. The NOEL
for maternal toxicity was 300 mg/kg/day. The LOEL was 900 mg/kg/day,
based on reduced body weight gain and reduced food consumption. The
NOEL for developmental toxicity was 900  mg/kg/day, the highest dose
tested (guideline 83-3; MRID 41151401).

e.      Mutagenicity

       Dimethoxane is not mutagenic in the standard Ames battery of
bacterial  strains, with  or  without  activation  (MRID  41144101).
Dimethoxane did not cause  DNA damage or induce repair in the rat
hepatocyte unscheduled DNA synthesis  assay  (MRID  41144103).
However, the chemical was clastogenic in Chinese hamster ovary cells
with activation but was negative without activation (guideline 84-2; MRID
41144102).

f.      Toxic Endpoints of Concern:

       Based upon the review of the toxicology data base for dimethoxane,
neither short term (1 to 7 days) nor intermediate term (1 week to several
months)  toxicological   endpoints  for  occupational/residential  risk
assessment  were identified  due to  low  toxicity  and minor effects.
Therefore, no assessment is required for acute dietary risk or occupational
risk.

-------
       g.     Reference Dose

             This chemical has no food uses, therefore, no RfD value has been
       identified for dimethoxane.

2.     Exposure Assessment

       a.     Occupational and Residential

             1.      Use Patterns

                    As    indicated,    dimethoxane    is    a    fungicide,
             microbiocide/microbiostat and bacteriostat formulated as a liquid
             soluble  concentrate.      It  is  used  as  a  preservative  in
             commercial/industrial   formulation   of   in-can   latex   paints
             (approximate 0.1% by weight as maximum dosage), in fuel/oil
             storage tank bottom water  (approximate 0.1%  by  weight as
             maximum dosage), emulsion paints and inks, specialty industrial
             products/preservatives,  textile  presevatives,  adhesives,  leather
             processing liquors, and distillate fuels.

                    Giv-Gard DXN, the only product containing dimethoxane
             currently registered (Reg. No. 824-7), contains 87% dimethoxane.
             This product is registered only for use in industrial settings. Both
             open-pour and closed delivery systems are acceptable application
             methods for dimethoxane. There are no residential uses registered
             for the dimethoxane product.

                    There are no registered uses of dimethoxane within the
             scope of the Agency's Worker Protection Standard for Agricultural
             Pesticides (WPS); i.e., no uses registered for use in the production
             of food, feed, fiber, ornamental, turf, or tree crops.

             2.      Handler (Mixer/Loaders and Applicators) Exposure

                    Dimethoxane exposure to handlers is possible when workers
             handle the preservative in industrial settings. For those handlers
             using open pouring application methods, there is the potential for
             respiratory, dermal, and eye exposure. By comparison, potential
             exposure to handlers using closed delivery systems is expected to
             be significantly reduced.

-------
             3.      Post Application Exposure

                    There are several types of potential exposure to persons
             after application is complete.  These include:

                    a.     Potential exposure, especially inhalation exposure,
                          to industrial/manufacturing  workers immediately
                          after dimethoxane use.

                    b.     Potential exposure,  including dermal and inhalation
                          exposure,  when  substances  (such   as  paints)
                          containing dimethoxane are used.

                    Based on dimethoxane use  patterns, exposure to workers in
             the  industrial   setting  is   possible  immediately   following
             dimethoxane use. Due to the chemical properties of dimethoxane
             (low vapor pressure, etc.), post-application inhalation exposure to
             workers is expected to be minimal. Also, exposure to  individuals
             who use dimethoxane products (such as paints) is possible, but the
             amount of dimethoxane contained in these products is so small that
             resulting toxic effects are expected to be negligible.

3.     Risk Assessment

       a.     Occupational and Residential

             All uses of dimethoxane are outside of the  scope of the Agency's
       Worker  Protection  Standard  and there  are  no  special  toxicological
       concerns  about dimethoxane that warrant the establishment of active-
       ingredient-based personal protective equipment (PPE).

             Based on  the available toxicity information and use patterns for
       dimethoxane, the Agency has completed a qualitative  assessment of
       exposure  and cancer risk based on  the National Toxicology  Program
       studies and conservative occupational  exposure assumptions.   The
       assessment indicates no significant human cancer risk.

             Based on the existing use patterns of dimethoxane, post-application
       exposure  data are not required.  Due to the chemical properties of
       dimethoxane  (low vapor pressure, etc.),  post-application inhalation
       exposure to workers is expected to be minimal.   Also, exposure to
       individuals who use dimethoxane products (such as paints) is possible, but

-------
             the amount of dimethoxane contained in these products is so small that
             resulting toxic effects are expected to be negligible.

C.     Environmental Assessment

       1.     Ecological Toxicity Data

             The ecotoxicological data base is adequate to characterize the toxicity of
       dimethoxane to nontarget terrestrial and aquatic organisms when used as an
       indoor, nonfood use microbiostat/fungistat.  There is no direct use or application
       of this peticide outdoors.  Any significant hazard would presumably result from
       a transportation accident, spill, or purposeful discharge into the environment. Any
       such environmental contamination would  have minimal impact on avian and
       aquatic species given the results of the studies described below.

             a.     Toxicity to Terrestrial Animals

                    (1)    Birds, Acute and Subacute

                          In order to establish the toxicity of dimethoxane to birds, the
                    following tests are required using the technical grade material:  one
                    avian single-dose oral (LD50) study on one  species (preferably
                    mallard or bobwhite quail); one subacute dietary study (LC50) on
                    one species of waterfowl  (preferably  the mallard duck) or one
                    species of upland game bird (preferably bobwhite quail or ring-
                    necked pheasant).

       basis.  The guideline requirements are fulfilled. (MRID 41962502,
       41962503 and 41962504)

       b.     Toxicity to Aquatic Animals

             (1)    Freshwater Fish

                    In  order to establish the toxicity  of dimethoxane  to
             freshwater fish, the minimum  data required on the technical grade
             of the active ingredient is one freshwater fish toxicity study. The
             study should use a coldwater species (preferably the rainbow trout)
             or a warmwater species (preferably the bluegill sunfish).

       Although the submitted 96-hour acute toxicity  study did not define a
precise LC50 value, the results did demonstrate that dimethoxane is not more than
slightly toxic to both cold and warm water fish.   The study was scientifically
sound, but the test deviated from specified methods in the EPA standard guideline
protocol such that in lieu of a calculated LC50, the test indicated the LC50 to be
greater than  37  ppm of active ingredient.   A greater than 100 ppm toxicity
category indicates that the pesticide's toxicity category is practically nontoxic to
aquatic organisms.  The No Observed Effect Concentration (NOEC) was
                             11

-------
determined to be 1 ppm. The guideline requirement is not fulfilled; however, at
this time, dimethoxane is registered only for indoor uses.  As a result, minimal
exposure to wildlife is expected.  Therefore, the data are sufficient for the indoor
use pattern  such that the study does not need to be repeated. (MRID 41936701)
             (2)
             Freshwater Invertebrates
                    The minimum testing required to assess the hazard  of
             dimethoxane to freshwater invertebrates is a freshwater aquatic
             invertebrate toxicity test,  preferably using first instar Daphnia
             magna or early instar amphipods, stoneflies, mayflies, or midges.

Conclusions
not more than slightly

       Although the submitted 48-hour acute toxicity study did not define a
precise EC50 value, the results did demonstrate that dimethoxane is not more than
slightly toxic to aquatic invertebrates.  The study was scientifically sound, but the
test deviated from specified methods in the EPA standard guideline protocol such
that in lieu of a calculated EC50, the test indicated the EC50 to be greater than 24
ppm of active ingredient.  A greater than 100 ppm toxicity category indicates that
the pesticide's toxicity is practically nontoxic to aquatic organisms.  The  No
Observed Effect Concentration (NOEC) was determined to be  13  ppm.  The
guideline requirement is not fulfilled;  however, at this  time, dimethoxane is
registered only for indoor uses.  As a  result,  minimal exposure to wildlife is
expected.  Therefore, the data are sufficient for the indoor use pattern such that the
study does not need to be repeated. (MRID 41962501)
2.
Environmental Fate
       a.
             Environmental Fate Assessment
             The Agency has waived the requirement for a hydrolysis study.
       The available data indicate that the major route of degradation is abiotic
       hydrolysis aided by microbial mediated degradation.  Further, the data
       indicate that dimethoxane is highly unstable in water with over 50% of the
       compound hydrolyzed in 2 hours. Dimethoxane is purported to react with
                             12

-------
                    water to  form acetic acid and a transient intermediate, dioxinol.  The
                    dioxinol then breaks down into acetaldehyde and aldol. The breakdown
                    into acetic acid and dioxinol is completed in 14 hours.

             3.     Exposure and Risk Characterization

                          Risk assessments are not conducted on nontarget organisms for
                    microbiocides  having indoor  nonfood uses without  effluents.   The
                    preservative uses of dimethoxane in emulsion paints, emulsion inks, jet
                    fuels, leather processing liquors, coatings, specialty industrial products,
                    textiles and adhesives are expected to result in minimal to no exposure to
                    the environment. The jet fuel use of dimethoxane, however, is associated
                    with periodic releases into the environment based on purging of jet fuel
                    storage tanks of "water  bottoms" (small areas  of condensation  on the
                    bottom of the tank, which if not removed could cause leakage from rust
                    formation weakening the tank wall).  However, the hazard to wildlife and
                    aquatic organisms from these registered indoor nonfood uses is expected
                    to be minimal because dimethoxane is not more than slightly toxic to fish
                    and aquatic invertebrates, and  slightly to practically nontoxic to birds.
                    Tank bottom water must be disposed of in  accordance  with the U.S.
                    Environmental Protection Agency's Resource Conservation and Recovery
                    Act (RCRA).

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 reregi strati on.  The Agency has previously  identified and
       required the submission of the generic (i.e. active ingredient specific) data required to
       support reregi strati on of products containing dimethoxane  active ingredients.  The
       Agency has completed its review of these generic data, and has determined that the data
       are sufficient to support reregistration of all products containing dimethoxane. Appendix
       B identifies  the generic data requirements that the Agency  reviewed as part of its
       determination of reregistration eligibility of dimethoxane, and lists the submitted  studies
       that the Agency found acceptable.

             The data identified in Appendix B were sufficient to allow the Agency to assess
       the registered uses of dimethoxane and to determine that  dimethoxane can be used
       without resulting in unreasonable adverse effects to humans and the environment.  The
       Agency therefore finds that all products containing dimethoxane as the active ingredients
                                          13

-------
are eligible for reregi strati on.  The reregi strati on of particular products is addressed in
Section V of this document.

       The Agency made its reregistration eligibility determination based upon the target
data base required for reregistration, the current guidelines for conducting acceptable
studies to generate such data, published scientific literature, etc. and the data identified
in Appendix B.  Although the Agency has found that all uses of dimethoxane are eligible
for reregistration,  it  should be understood  that the Agency  may  take  appropriate
regulatory action, and/or require the  submission of additional  data to  support  the
registration  of products containing  dimethoxane, if new  information  comes to  the
Agency's attention  or if the data requirements for registration (or the guidelines  for
generating such data) change.

B.     Determination of Eligibility Decision

       1.     Eligibility Decision

             Based  on the reviews of the  generic data  for  the active ingredients
       dimethoxane,  the Agency has sufficient information on the  health effects of
       dimethoxane and on its potential for causing adverse effects in fish and wildlife
       and the  environment.  The Agency has determined that dimethoxane products,
       labeled and used as specified in this Reregistration Eligibility Decision, will  not
       pose unreasonable risks or adverse  effects  to  humans or the  environment.
       Therefore,  the Agency concludes  that  all  uses for the product  containing
       dimethoxane are eligible for reregistration.

       2.     Eligible and Ineligible Uses

             The Agency has determined that all uses of dimethoxane are eligible  for
       reregistration.

C.     Regulatory Position

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

       1.     Labeling Rationale

             Dimethoxane is classified as a strong skin sensitizer.  Therefore,  the
       Agency requires a precautionary statement about skin sensitization to be placed
       on the labeling.  The minimum personal protective equipment (PPE) for users of
                                    14

-------
             Giv-Gard DXN is long-sleeved shirt, long pants,  shoes, socks, and chemical-
             resistant gloves.

V.    ACTIONS REQUIRED OF REGISTRANTS

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

      A.     Manufacturing-Use Products

             1.     Additional Generic Data Requirements

                   The generic data base supporting the reregi strati on of dimethoxane for the
             above eligible uses has been  reviewed and  determined to be  substantially
             complete. However, an hydrolysis study is required as confirmatory data.

      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

             Labeling Requirements

             The Agency is requiring the following labeling statements to be located on the
             product:

             "This product has not been cleared  under the Federal Food Drug and
             Cosmetic Act for use in the manufacture of adhesives and coatings that
             may come in contact with food."
                                         15

-------
             Handler (Mixer, Loader, Applicator, Etc.) Personal Protective Equipment
       (PPE):  The PPE for pesticide handlers will be based on the acute toxicity of the
       end-use product.

       Application Restrictions:
       "Do not apply this product in a way that will contact workers or other
       persons. Only protected handlers amy be in the area during application."

       Engineering Controls:
       "When handlers use closed metering systems, the handler requirements
       may be reduced or modified to long-sleeve shirt, long pants, shoes, and
       socks."

       User Safety Requirements:
       "Follow manufacturer's instructions for cleaning/maintaining PPE.  If no
       such instructions for washing, use detergent and hot water.  Keep and wash
       PPE separately from other laundry."

       User Safety Recommendations:
       "Users should remove clothing immediately if pesticide gets inside.  Then
       wash thoroughly and put on clean clothing."

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

       Skin Sensitization Statement: [insert in the "Hazards to Humans (and Domestic
       Animals)" section of the Precautionary Statements]

       "This product may cause skin sensitization reaction in some people."

C.     Existing Stocks

       Registrants may generally distribute and sell products bearing old labels/labeling
for 26  months from the date of the issuance of this Reregi strati on 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 the
dimethoxane product bearing old labels/labeling for 26 months from the date of issuance
                                   16

-------
of this RED.  Persons other than the registrant may distribute or sell the product 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 reregi strati on for active
ingredients within the case dimethoxane covered by this Reregi strati on Eligibility Decision
Document. It contains generic data requirements that apply to dimethoxane 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

                               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
             as (19??), the Agency was unable to determine or estimate the date of the
             document.
                                           30

-------
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.

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)
       (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.

       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
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
                                            40

-------
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(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, 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
                                             41

-------
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:

       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

                                            42

-------
              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 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

                                            43

-------
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
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.
                                           44

-------
       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

             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
UNACCEPTABLE

       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

                                            45

-------
       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
risk concerns will be determined on case-by-case basis.
                                             46

-------
       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.
                                           47

      INSTRUCTIONS FOR COMPLETING THE REQUIREMENTS STATUS AND
         REGISTRANT'S RESPONSE FORM FOR PRODUCT SPECIFIC DATA

Item 1-3      Completed by EPA.  Note the unique identifier number assigned by EPA in Item
             3   This number must  be used in the transmittal document  for  any data
             submissions in response to this Data Call-In Notice.

Item 4.       The  guideline reference numbers of studies  required to  support the product's
             continued registration  are identified.   These  guidelines,  in  addition to  the
             requirements specified in the Notice, govern the conduct of the required studies.
             Note that series 61 and 62 in product chemistry are now listed under 40 CFR  158.155
             through 158.180, Subpart C.

Item 5.       The study title associated with the guideline reference number is identified.

Item 6.       The use pattern(s) of the pesticide associated with the product specific requirements
             is (are) identified. For most product specific data requirements, all use patterns are
             covered by the data requirements. In the case of efficacy data, the required studies
             only pertain to products which have the use sites and/or pests indicated.

Item 7.       The  substance to be tested is identified by EPA. For product specific data, the
             product as formulated for sale and distribution is the test substance, except in rare
             cases.

Item 8.       The due date for submission of each study is identified. It is normally based on 8
             months after issuance of the Reregistration  Eligibility Document unless EPA
             determines that a longer time period is necessary.

Item 9.       Enter  only one of the following response codes for each data requirement to
             show how you intend to comply with the data requirements listed in this table.
             Fuller descriptions of each option are contained in the Data Call-In Notice.

                                          52

-------
      product to qualify for this option. I certify that another party in the agreement is
      committing to submit or provide the required data; if the  required  study is not
      submitted on time, my product may be subject to suspension.  By the specified due
      date, I will also submit: (1) a completed "Certification With Respect To Data
      Compensation Requirements" form (EPA Form 8570-29) and (2) two completed
      and signed copies of the Confidential  Statement of Formula (EPA Form 8570-4).

3.     I have made offers to share in the cost to develop data (Offers to Cost Share).  I
      understand that this option is available  only for acute toxicity or certain efficacy data
      and  only if EPA indicates in an attachment to this Data Call-In Notice that my
      product is similar enough to another  product to qualify for this option.  I am
      submitting evidence that I have made an offer to another registrant (who has an
      obligation to submit data) to share in the cost of that data. I am also  submitting a
      completed "Certification of Offer to Cost Share in the Development Data" form
      I am including a copy of my offer and proof of the other registrant's receipt of that
      offer.  I  am identifying the party which is committing to submit or provide the
      required  data; if the required study is not submitted on time, my product may be
      subject to suspension.  I understand that other terms under Option 3 in the Data Call-
      in Notice (Section III-C.l.) apply as well.  By the specified due date,  I will also
      submit: (1) a completed "Certification With Respect To  Data Compensation
      Requirements" form (EPA Form  8570-29) and (2) two completed and signed
      copies of the Confidential Statement of Formula (EPA Form 8570-4)

4.     By the specified due date, I will submit an existing study that has not been submitted
      previously to the Agency by anyone (Submitting an Existing Study).  I certify that
      this study will meet all the requirements for submittal of existing data outlined in
      Option 4 in the Data Call-In Notice (Section III-C.l.) and will meet the attached
      acceptance criteria (for acute toxicity and product chemistry data). I will attach the
      needed supporting information along with this response. I also certify that I  have
      determined that this study will fill the data requirement for which I have indicated
      this choice. By the specified due date,  I will also submit a completed "Certification
      With Respect To Data Compensation Requirements" form (EPA Form 8570-29)
      to show what data compensation option I have chosen. By the specified due date, I
      will   also  submit: (1)  a  completed  "Certification With Respect  To  Data
      Compensation Requirements" form (EPA Form 8570-29) and (2) two completed
      and signed copies of the Confidential  Statement of Formula (EPA Form 8570-4).

5.     By the specified due date, I will submit or cite data to upgrade a study  classified by
      the Agency as partially acceptable and upgradable (Upgrading a Study). I will
      submit evidence of the Agency's review indicating that the study may be upgraded
      and what information is required to do so. I will provide the MRID or Accession
      number of the study at the due date. I understand that the conditions for  this option
      outlined Option 5 in the Data Call-In Notice (Section III-C.l.) apply.  By the
      specified due date, I will also submit: (1) a completed  "Certification With Respect
      To Data Compensation Requirements" form (EPA Form 8570-29) and (2) two

                                   53

7.
             completed and signed copies of the Confidential Statement of Formula (EPA
             Form 8570-4)

             By the specified due date, I will cite an existing study that the Agency has classified
             as acceptable or an existing study that has been submitted but not reviewed by the
             Agency (Citing an Existing Study).  If I am citing another registrant's study, I
             understand that this option is available only for acute toxicity or certain efficacy data
             and only if the cited study was conducted on my product, an identical product or a
             product which EPA has "grouped" with one or more other products for purposes of
             depending on the same data. I may also choose this option if I am citing my own
             data. In either case, I will provide the MRID or Accession number(s) for the cited
             data on a "Product Specific Data Report" form or  in a similar format.  By the
             specified due date, I will also submit: (1) a completed "Certification With Respect
             To Data Compensation Requirements" form (EPA Form 8570-29) and (2) two
             completed and signed copies of the Confidential Statement of Formula (EPA
             Form 8570-4)

             I request a waiver for this study because it is inappropriate for my product (Waiver
             Request). I am attaching a complete justification for this 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 P.R.
             Notice 86-5]. I understand that this is my only opportunity to state the reasons or
             provide information in support of my request. If the Agency  approves my waiver
             request, I will not be required to supply the data pursuant to Section 3(c)(2)(B) of
             FIFRA. If the Agency denies my waiver request, I must choose a method of meeting
             the  data requirements of this Notice by the due date stated by this Notice.  In this
             case, I must, within 30 days of my receipt of the Agency's written decision, submit
             a revised "Requirements  Status  and Registrant's Response" Form indicating the
             option chosen. I also understand that the deadline for submission of data as specified
             by the original data call-in notice will not change. By the specified  due date, I will
             also submit: (1) a completed "Certification With Respect To Data Compensation
             Requirements" form (EPA Form 8570-29) and (2) two  completed and signed
             copies of the Confidential Statement of Formula (EPA Form 8570-4)

Items 10-13.  Self-explanatory.

NOTE:      You may provide additional information that does not fit on this form in a signed
             letter that accompanies this form.  For example, you may wish to report that your
             product has already been transferred to another company or that you have already
             voluntarily canceled this product.  For these cases, please supply all relevant details
             so that EPA can ensure that its records are correct.
