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 Dowicil®CTAC
which includes the active ingredients Dowicil®75 and Dowicil®150.  The enclosed
Reregistration Eligibility Decision (RED) contains the Agency's evaluation of the data base of
this [these] chemical [s],  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.

       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
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.

EXECUTIVE SUMMARY
       The U.S. Environmental Protection Agency (hereafter referred to as "the Agency") has
completed an assessment of the potential human health and environmental risks associated with
the pesticide uses of l-(3-chloroallyl)-3,5,7-triaza-l-azoniaadamantane chloride  (Dowicil®
CTAC).  There are two active ingredients included in this assessment, Dowicil®75 which
contains a ratio of both the cis- and trans-isomers of l-(3-chloroallyl)-3,5,7-triaza-l-
azoniaadamantane chloride, and Dowicil®150 which contains only the cis-isomer of l-(3-
chloroallyl) -3,5,7-triaza-1 -azoniaadamantane chloride.

       This Reregistration  Eligibility Decision (RED) also addresses the reregistration
requirements for products containing both Dowicil®75 and Dowicil® 150 for currently
registered uses.   These products are used as preservatives in oil recovery drilling muds and
packer fluids, metal working cutting fluids, latex paints, industrial adhesives and coatings,
latex emulsions, detergent floor wax emulsions, floor polishes, inks, laundry starch, spinning
emulsions, and pulp and paper coatings, finishes and printing colors as components of paper
and paperboard intended for use in contact with aqueous, fatty,  dry  bulk, and dry foods. They
are also applied as microbicides/microbistats to secondary oil injection water as  a water
treatment.

       The Agency has determined that the uses  of Dowicil®75  and  Dowicil® 150 as currently
registered will not cause unreasonable risk to humans or the environment and these uses  are
eligible for reregistration. The Agency has concerns about the potential for workers to be
exposed to formaldehyde, a degradate, from the industrial and residential uses.  However,  the
Agency believes that the risks of formaldehyde for the industrial uses is low and should be
regulated by the Occupational Safety and Health  Administration (OSHA) through their
formaldehyde monitoring program and the potential for exposure in  residential settings is
minimal. The Agency also  has concerns about possible adverse affects to aquatic organisms
from the discharge of effluent from industrial uses. However, the Agency is requiring as part
of this RED that product labels be amended to contain appropriate label restrictions for
industrial discharge in the National Pollutant Discharge Elimination  System.

       Accordingly, the Agency has determined  that all products containing either active
ingredient Dowicil®75 or Dowicil® 150 are eligible for reregistration and will be reregistered
when acceptable labeling and product-specific data are submitted and/or cited.  Before
reregistering the products containing Dowicil®75 or Dowicil®150, 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 determined to be
eligible for reregistration.

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 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 registration" 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 chemical  case Dowicil®CTAC and its two active ingredients Dowicil®75, a racemic
mixture of l-(3-chloroallyl)-3,5,7-triaza-l-azoniaadamantane chloride, and Dowicil®150, the
cis isomer of this chemical and their registered uses.  The document consists of six sections.
Section I is the introduction. Section II describes Dowicil®75 and Dowicil®150,  their 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 Dowicil®75 and Dowicil®150. Section V discusses the reregistration
requirements for Dowicil®75 an Dowicil®150. 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.

CASE OVERVIEW-Dowicil®CTAC
      The Agency will use the case name Dowicil®CTAC for the case containing the two
active ingredients Dowicil®75 and Dowicil®150.  The active ingredient Dowicil®75 contains
both the cis-(. 53%) and the trans-(. 44%) isomers of l-(3-chloroallyl)-3,5,7-triaza-l-
azoniaadamantane chloride. The  active ingredient Dowicil®150 contains only the cis-isomer of
l-(3-chloroallyl)-3,5,7-triaza-l-azoniaadamantane chloride. The Agency will use the  case
name Dowicil®CTAC in this document when referring to both active ingredients together.
There are sections in the assessment were it will be necessary to reference each active
ingredient separately.  In those instances the Agency will use the trade names Dowicil®75 and
Dowicil®150 for the specific chemical characteristics or to represent the percentage of active
ingredient being referenced.

D.     Regulatory  History

       A pesticide product containing Dowicil®150 was first registered in the United
States in 1964 as a microbicide/microbistat.  A second registration for Dowicil®75 was
granted in 1972 for use as a  preservative for paints, latexes,  metalworking lubricants
and to other industrial formulations to prevent deterioration from bacteria and fungi.

-------
             Dowicil®CTAC meets the requirement of Food Additive regulations under 21
       CFR Section 175.105 for use as a preservative in adhesives, 21 CFR 176.1680 as a
       preservative of polyurethane resins in contact with dry bulk foods, 21 CFR 176.170 for
       preservation of components of pulp and paperboard intended for use in contact with
       aqueous and fatty foods, and 21 CFR 176.180 for preservation of paper and
       paperboard intended for use in contact with dry foods.

             In 1987 the Agency issued the Antimicrobial Data Call-in Notice for chronic
       and subchronic toxicity data requirements for these  two active ingredients and other
       antimicrobials. The Agency issued a second data call-in under reregistration Phase 4 in
       of March 1992. This required the registrant to provide appropriate chemistry,
       toxicological and environmental fate  data on these active ingredients to support
       reregistration. This Reregistration Eligibility Decision reflects a reassessment of all
       data which were submitted in response to these data call-ins.

III.    SCIENCE ASSESSMENT

       A.     Physical Chemistry Assessment

             The physical chemistry assessment for Dowicil®CTAC was done on
       Dowicil®75.  The Agency believes that the physical chemistry characteristics of
       Dowicil®150 will be similar to Dowicil®75 since they are related isomers.

B.     Human  Health Assessment

       The toxicology data base for Dowicil®CTAC is adequate for reregistration
eligibility.  Due to the similarities of the two active ingredients the Agency accepted
toxicology studies conducted using either Dowicil®75  (sometimes referred to under
trademark name Dowicil®100) or Dowicil®150  (sometimes referred to under trademark
name Dowicil®200.)

       1.     Toxicology Assessment

             a.     Acute Toxicity

                    An acute oral toxicity study in rats found the LD50 for
             Dowicil®150 was 2664 mg/kg for both sexes (see Table 1).  Clinical
             signs were lethargy, diarrhea, lacrimation, and tremors, placing
             Dowicil®CTAC in toxicity category III  (guideline 81-1; MRID
             00093902). An acute dermal toxicity study with rabbits found the LD50
             for Dowicil®150 was 923 mg/kg, placing Dowicil®CTAC in toxicity
             category II (guideline 81-2; MRID  00093902).  An acute inhalation
             toxicity study with rats found the LC50 was greater than 4.7 mg/L,
             placing Dowicil®CTAC in toxicity  category IV (guideline 81-3; MRID
             42420401).

                    A primary eye irritation study with Dowicil®150 in rabbits
             produced slight to moderate conjunctival redness and slight discharge,
             which  cleared by 72 hours. There  was  slight irritation, toxicity category
             III (guideline 81-4; MRID 00093902).  Dowicil®150, in a primary
             dermal irritation study with rabbits, produced a very slight edematous
             reaction on intact skin.  There was  slight irritation placing
             Dowicil®CTAC into toxicity category IV (guideline 81-5; MRID
             00093902). The dermal sensitization potential of Dowicil®150 was
             tested with guinea pigs and it was not a dermal  sensitizer (guideline 81-
             6; MRID 00093902).

b.     Subchronic Toxicity

       New Zealand white rabbits were given daily dermal applications of
Dowicil®75 for 13 weeks. The doses were 0, 50, 200, or 1000 mg/kg/day.
The only treatment related  effect was a dose-dependent  increase in
ulcerative dermatitis,  at the treatment site, that was correlated with  the
abrasions from  clipping.   The NOEL  for systemic toxicity was 1000
mg/kg/day (guideline 82-4; MRID 40650201).

       One study was conducted to determine the level of Dowicil®75 in
the diet which would result in complete acceptance of the diet by rats. Ten
rats/sex/group were administered the chemical in the diet at dosages of 0,
1, 2 or 4 mg/kg/day for 90 days. The only parameters evaluated were body
weight, food consumption and organ weight (absolute and relative). Male
rats in the 4 mg/kg/day group had a significant decrease in body weight at
approximately  36%  of the weighing periods. This  group also had a
significant  decrease  in food consumption throughout  the  study. The
absolute weight  of the  heart  in  the  4 mg/kg/day  group males was
significantly decreased. The relative  weight of the brain and liver were
increased in the 4.0 mg/kg/day group females. This study was classified
as supplementary but was not required for reregistration.  The study was
performed to investigate a specific toxicological endpoint (MRIDf 46358).

-------
       In another study, Dowicil®75 was administered in the diet to groups
of 10 rats/sex/group at dosages of 0, 7.5, 15 , 30 or 60 mg/kg/day for 90
days. Mean body weight was significantly decreased in all the treated males
and  females throughout the study. Overall mean body weight gain was
decreased  in  all  the  treated  groups.  Mean food consumption  was
significantly decreased in the treated males, especially at the beginning of
the study.  Although  all of the  treated female groups  had significantly
reduced  intake at some time  during the study,  females  were not as
frequently affected as  males. Calculation of food efficiency values for the
overall study  and  for the latter  half of the study showed that the major
effect of decreased food intake on body weight occurred at the beginning
of the  study. However, the decrease in food efficiency does indicate that
the chemical had a toxic effect on body weight that cannot be accounted for
solely  by decreased food consumption. The only other possible effect of
treatment was an  increase  in the incidence of minimal hepatocellular
swelling in the 60 mg/kg/day group males (0/5 in the control vs.  3/5 in the
60 mg/kg/day group).  This study is classified as supplementary due to the
absence of clinical observation data and legible summary tables for the
organ weight data  (MRID# 111075).

       In a dog study, Dowicil®75 was administered in gelatin capsules to
four beagle dogs/sex/group at dosages of 0, 7.5, 15 or 30 mg/kg/day for
90 days. One  female  in the 30 mg/kg/day was sacrificed due to general
deterioration on the 84th day of the study; necropsy revealed ascites with
evidence of liver  toxicity. The  only  other lexicologically  significant
findings during the  study included a significant decrease in the hematocrit,
hemoglobin and white blood count measurements  in the 30 mg/kg/day
group  males and histopathological changes, especially in the liver, in the
30 mg/kg/day  group males and females. The incidence and/or severity of
several findings in the liver were increased in the 30 mg/kg/day group
males  and females including  the following: obliterative vasculitis and
perivasculitis of the hepatic blood  vessels; perivascular and pericholangiolar
infiltration of mononuclear cells; and hyperplasia of the reticuloendothelial
cells lining the hepatic sinusoid.  This study is classified as supplementary
due  to the  absence of legible summary tables for hematology and organ
weight data (MRID#127915).

-------
       c.     Developmental Toxicity

             A dermal developmental toxicity study was conducted with Fischer
       344 rats.  Doses of 0, 250, or 500 mg/kg/day of Dowicil®75 as a 50%
       aqueous solution were applied to the dorsal skin daily on gestation days 6
       through  15.  No significant adverse effects from treatment with the test
       compound were found but the study was considered adequate because the
       doses were sufficiently high (guideline 83-3; MRID 40349701).

       d.     Mutagenicity

             Dowicil®75 was mutagenic  in the in vitro Chinese hamster ovary
       cell HGPRT forward mutation assay with activation but nonmutagenic
       without activation (guideline 84-2(a); MRID 40545101).  Dowicil®75 was
       negative in the rat hepatocyte unscheduled DNA synthesis assay (guideline
       84-4; MRID 40545103). It was negative also  in the mouse micronucleus
       test (guideline 84-2 (b); MRID 40545102).

2.      Exposure Assessment

       a.     Occupational and Residential

             Due to its low toxicity and the lack of  a toxicological endpoint of
       concern,  an exposure  assessment  is not required for Dowicil®CTAC.
       However, based on the studies submitted by the registrant (GDLN 161-1,
       MRID# 43192101 and MRID# 43577601), the Agency has determined that
       formaldehyde is released  from the decomposition of Dowicil®CTAC in
       aqueous solution. The Agency is concerned with formaldehyde since it has
       significant toxic effects of its own,  and has been classified by the Agency
       as a Group B I/Probable Human Carcinogen (Integrated Risk Assessment
       System, 5/1/91).

             The potential for exposure to Dowicil®CTAC and/or formaldehyde
       exists for two groups of individuals: 1) Occupational—workers involved in
       the  industrial setting  (addition of the biocide during the  manufacturing
       process);  and  2)  Residential—individuals in the home  setting where
       Dowicil®CTAC products may be used.

             For residential uses, the Agency has determined that the potential
       exposure to Dowicil®CTAC  is  minimal.  A  study submitted  by  the
       registrant for carpet adhesives containing  Dowicil®CTAC indicates that
       formaldehyde does not pose an exposure hazard  (MRIDf 43577601).
                            10

-------
             For industrial uses, the Agency has determined that Dowicil®CTAC
       exposure for most workers to is low because of the current use patterns and
       available use information. Therefore, exposure to Dowicil®CTAC not of
       concern. The Agency believes workers in industrial settings are adequately
       protected against exposure to formaldehyde by the Occupational Safety and
       Health Administration. OSHA has a comprehensive workplace standard for
       formaldehyde for the protection of workers in the industrial setting due to
       formaldehyde-release in the workplace. The OSHA formaldehyde standard
       was established as a rule in May 1992, and set a permissible exposure level
       (PEL) of .75 ppm in the workplace. The  standard also proscribes that
       certain actions should be taken if monitoring shows levels of .50 ppm. This
       standard requires monitoring before workers enter the premises following
       use of formaldehyde, or when potential ambient formaldehyde is generated
       from other chemicals.

             Two  incident  cases  have  been reported  to  the  Agency  for
       Dowicil®CTAC. The first case, reported in June  1993, involved  7 workers
       and the specific active ingredient is unknown.  This incident was caused by
       a misuse of the product.  In the second case, reported in August, 1994, a
       woman in  Texas claimed  to have  developed chemical sensitivity  to
       Dowicil®75 in housepaint.  From  its review of this report, the Agency
       considers the information  insufficient to show a causal relationship between
       Dowicil®75 and the reported  chemical sensitivity.  Other than these  to
       cases, no other human incidents have been reported to the Agency.

             All uses of Dowicil®CTAC are outside the scope of the Worker
       Protection Standard  (WPS)  and requirements  for personal  protective
       equipment (PPE) for Dowicil®CTAC products are under the jurisdiction of
       OSHA.  The Agency requires that Dowicil®CTAC labels contain a label
       statement advising workers to wear chemical resistant gloves for the open-
       pouring of the end-use product.

3.     Risk Assessment

       a.     Occupational and Residential

             Based on the  use patterns  and toxicological information for the
       active  ingredients  Dowicil®75  and  Dowicil®150,  the  Agency  has
       determined that products containing the above active ingredients, labeled
       and used as specified in this RED, will not  pose  a significant risk  to
       humans. The Agency further believes potential risks in residential settings
       will be insignificant.  The occupational risks for potential exposure  to
       formaldehyde in the work place when Dowicil®CTAC is used are low and
       formaldehyde is currently monitored and regulated by OSHA.
                             11

-------
C.     Environmental Assessment

       In summary, Dowicil®CTAC dissipates by abiotic hydrolysis with slightly faster
rates of hydrolysis under acidic conditions than were  observed for neutral to alkaline
conditions. Dowicil®75 and Dowicil®150 have both been  classified as practically nontoxic
to slightly toxic to avian species, fish, aquatic invertebrates and terrestrial animals.  These
chemicals' environmental fate and ecological effects are described in more detail below.

       1.    Environmental Fate

             A hydrolysis study is required for industrial use pesticides in which effluent
       is potentially discharged into aquatic environments.   This  environmental fate
       guideline requirement is fulfilled for Dowicil®CTAC.

             a.     Environmental Chemistry, Fate and Transport

                    (1)    Hydrolysis

                    Uniformly radio-labeled Dowicil([14C]CTAC), at 58 ppm, degraded
             with a registrant calculated half-life of 1.1 days in a sterile pH 5  buffer
             solution that was incubated in the dark at 25°C; the hydrolytic half-lives
             were 2.7 and 2.2 days for pH 7 and 9 solutions,  respectively. Uniformly
             radio-labeled  [14C]CTAC,  at 1,004  ppm in 0.05 M  buffer  solutions,
             degraded more slowly than the 58  ppm  test solutions with  registrant
             calculated half-lives of 6.3, 13 and 26 days for  pH 5, 7 and 9  solutions,
             respectively.   Similar half-lives  were reported  for both cis-  and trans-
             isomers within each concentration range  test.

             The following degradates were identified:

                    * l-methyl-3,5,7-triaza-l-azoniaadamantane ([14C]-HMTA-CH3);

                    * the hydrochloride salt of hexamethylenetetramine ([14C]-HMTA;
                    maximum  concentration of less than  7 percent of the applied for
                    both [14C]-HMTA-CH3 and [14C]-HMTA at 10 days posttreatment);
                    and

                    * nonlabeled cis- and trans-3-chloroallylamines.

                    In the pH 5 solution, [14C]CTAC was a maximum of 59.11 percent
             (cis-) and 36.46 percent (trans-) of the applied immediately post treatment
             and a maximum of 27.46 percent (cis-) and 12.97 percent  (trans-) of the
             applied at 1 day posttreatment.  At day 5, [14C] CTAC was a maximum of
             2.99 percent (cis-) and 1.56 percent  (trans-) of the applied.
                                    12

-------
       In the pH 7 solution, [14C]CTAC was a maximum of 59.27 percent
(cis-) and 36.12 percent (trans-) of the applied immediately post treatment
and a maximum of 32.38 percent (cis-) and 21.69 percent (trans-)  of the
applied at 1 day post treatment.  At day 5,  [14C]CTAC was a maximum of
14.54 percent and 7.9 percent of the applied for the cis- and trans-isomers,
respectively.

       In the pH 9 solution, [14C]CTAC was a maximum of 45.54 percent
(cis-) and 27.25 percent (trans-) of the applied immediately post treatment
and a maximum of 26.83 percent (cis-) and 16.23 percent (trans-)  of the
applied at 1 day post treatment.  At day 5,  [14C]CTAC was a maximum of
7.96 percent (cis-) and 3.59 percent (trans-) of the applied.

       Material balances ranged from 95.5 to 102.2 percent of the applied
for the 50 ppm [14C]CTAC experiment.   Material balances ranged from
94.5  to 104.4 percent  of the applied for the  1,000 ppm  [14C]CTAC
experiment.

       Reaction rates for the [14C]-products suggested that an appreciable
amount of the [14C]-products may be precursors to [14C]-methylene glycol.
Based on an earlier hydrolysis study, formaldehyde forms as a degradation
product of CTAC (Gonsior and Billing,  1984).  The current hydrolysis
study indicates  that formaldehyde, when present in a dilute aqueous
solution, reacts with water to form  the hydrate, methylene glycol. Earlier
research indicates that after the addition of formaldehyde to a pH 7 solution
at 25° C, less than 0.01 percent remained as formaldehyde (Allinger  et al.,
1971).  The current hydrolysis  study considered formaldehyde  as  an
equilibrium mixture with methylene glycol.  This study fulfills the guideline
requirement,  (guideline 161-1; MRID 43192101)

b.     Environmental Fate Assessment

       Information  from the above hydrolysis  study  indicates that
Dowicil®CTAC is nonpersistent and degrades rapidly under acidic (pH 5)
conditions.    Under  neutral  to  alkaline  conditions  (pH  7-to-9),
Dowicil®CTAC degraded more slowly.
                      13

Aquatic Tier Ic Estimated Environmental Concentrations (EECs):

       The fundamental component of an aquatic exposure assessment for
the Agency is the Estimated Environmental Concentration or EEC.  An
aquatic EEC describes the frequency or probability that a chemical will be
found at a certain concentration in a specified environment or group of
environments as the result of its use pattern.

       To aid in the aquatic risk assessment, a screening level  calculation
called a Tier Ic EEC was developed by the  Agency.  A Tier Ic EEC
determines the maximum concentration occurring immediately downstream
from an industrial (point source) discharge site, and is calculated using very
conservative assumptions and does not address the environmental fate of the
pesticide,  and  therefore, may overestimate  the true  exposure of the
chemical.   However, it provides a clear demarcation such that if a Tier Ic
EEC does not exceed the established Level of Concern (LOG),  it indicates
that a pesticide poses little or no risk to the aquatic environment.  In the
same respect,  if the Tier Ic EEC does exceed the LOG,  it may indicate that
the pesticide can potentially adversely impact the environment.  For risk
assessment, these calculated EECs may be compared to acute exposure
LOCs  (based on the fact that these EECs estimate the concentration
immediately downstream  from a discharge site  and  that it assumes no
degradation of the chemical).  However, chronic exposure risk assessments
can be conducted using the Tier Ic EECs when a safety  factor (1/100 LC50)
is employed.

       EECs for high exposure and typical exposure are calculated.   The
EECs for the high exposure case are based on a return frequency of l-in-10
years.  The high exposure case represents a site that would be expected to
produce larger EECs than 90% of all  the sites with the specified use
pattern. A l-in-10 year EEC has a 10% probability of being equalled or
exceeded  in any single year at a given site, or could be equalled or
exceeded once every 10 years at that site over a long term average.  These
frequency  of occurrence and site assumptions are similar to the assumptions
used by the  Agency for modeling agricultural  pesticides.   The EECs
calculated for the typical exposure case represents a site that would be
expected to produce  larger EECs than 50%  of all the sites with the
specified use pattern.

       The Agency may regulate  pesticides using the high  (maximum)
exposure rather than the typical exposure to provide an added measure of
environmental protection.  Typical exposure is provided for refinement to
further characterize the risk. To calculate both EECs, the concentration in
the waste  stream was assumed to be the same as the application rate  (this
                      14

-------
assumes that no degradation occurred in the processing  stream).  The
concentration in  the  waste stream  was then  used to  calculate  the
concentration in the receiving water body immediately downstream from
the discharge site.

       Dowicil®CTAC is also used in pulp/paper mills; however it is not
used in the Whitewater stage of paper making. These waters are reused
several times and  are treated with a  variety of antimicrobial products.
Dowicil®CTAC is incorporated into the coating materials which provide the
desired aesthetic or strength characteristics  of the paper.  During the
coating process  the  water  is evaporated  and  the low residual  of
Dowicil®CTAC is incorporated into the coating.  Because the exposure of
Dowicil®CTAC from this use pattern is expected to be minimal, Tier Ic
EECs were not calculated for pulp/paper mill use.

       Dilution  factors  used to calculate  the EECs were  taken from an
array of dilution factors compiled by  the  Office of Pesticides and Toxic
Substance of EPA (OPTS, 1992). For each use pattern,  an appropriate
group of industrial sites was selected to represent the use. Table 1 lists the
Standard Industrial  Code (SIC) for  each industrial classification chosen for
a particular use pattern. If the use pattern was not specifically listed on the
Industrial Categories Summary Table, the Publicly  Owned Treatment
Works (POTW) which may also be referenced as SIC #4952 were used as
the default category.

       The  application  rates  of Dowicil®75  and  Dowicil®150  and
appropriate dilution factors used to calculate the EECs are listed in
Table 2.  The typical EEC was calculated by dividing the waste stream
concentration by the tabulated dilution factor for the mean  flow condition
at the median site. The high exposure EEC  was calculated by using a
dilution factor which represents a site that would be expected to produce
larger EECs than 90 percent of all sites with the specified use pattern.

                           (1)    Terrestrial Data

                                  In order to establish the toxicity of Dowicil®CTAC 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) and one subacute dietary study (LC50) on
                           one species of waterfowl (preferably the mallard duck) or upland
                           game bird (preferably bobwhite quail or  ring-necked pheasant).

                                  Given that the use  patterns of the products with these two
                           chemicals are not likely to expose wild mammals or honey bees, the
                           Agency has not required toxicological testing for these two species.
                                           17

-------
(a)     Avian Acute Toxicity

       The Agency has reviewed two studies which indicate that
Dowicil®CTAC ranges from slightly toxic to practically nontoxic
to birds on an acute oral basis (Table 4). The guideline requirement
for the avian acute oral LD50 study is fulfilled,  (guidelines 71-1 (a);
MRID 00071725 and 42814703)

(b)    Avian Subacute Dietary Toxicity

       Dowicil®CTAC is slightly toxic to practically nontoxic to
birds  on  a subacute  dietary  basis  (Table  5).  The  guideline
requirement is  fulfilled, (guidelines  71-2(a),  71-2(b);  MRID

(2)     Aquatic Data

(a)     Freshwater Fish Toxicity

       In order  to  establish  the  toxicity of a  microbicide  to
freshwater fish, the minimum data required on the technical grade
of the active ingredient is one freshwater fish  toxicity study.
                18

-------
       The  results of the aquatic  toxicity studies indicate  that
Dowicil®CTAC  is  slightly toxic  to  practically  nontoxic to
freshwater fish (Table 6).  The guideline  requirement for acute
toxicity testing of the  technical on  freshwater  fish is fulfilled
(guidelines  72-1 (a),   72-1 (c);  MRID  00125029,  42814701,
42814702).

(b)    Freshwater Invertebrate Toxicity

       The  minimum testing required to assess the hazard of a
microbicide to freshwater invertebrates is one freshwater aquatic
invertebrate toxicity test, preferably using first instar Daphnia
magna or early instar amphipods, stoneflies, mayflies, or midges.
At an EC50  of 42  ppm, Dowicil®75 is slightly toxic to Daphnia.
Data  for an acute invertebrate toxicity test  was submitted for
Dowicil®75 but not for Dowicil®150.  However, based on available
freshwater  fish  toxicity  data  (see  Table 6),  which  indicate
Dowicil®150 is less toxic than Dowicil®75 to  aquatic organisms,
this study would not add any useful scientific information and is,
therefore, waived. The guideline requirement for acute toxicity
testing on freshwater invertebrates is fulfilled,  (guideline 72-2(a);
MRID 00125029)

(c)     Estuarine/Marine Toxicity

       Estuarine/marine acute toxicity studies are  required under
the current 40 CFR Part  158 to support use in once-through cooling
towers, oil  recovery drilling muds/packer  fluids, secondary  oil
recovery injection waters, and pulp  and paper mills.   The
requirement for this category includes a 96-hour LC50 for  an
estuarine fish (sheepshead minnow preferred),  a 96-hour LC50 for
                19

-------
shrimp (mysid preferred), and a 48-hour embryo-larvae study or a
96-hour shell deposition study (eastern oyster preferred).  Estuarine
toxicity  testing reveals  that  Dowicil®150 is slightly toxic to
estuarine   organisms.  The  estuarine   data  requirements   for
Dowicil®150 have been fulfilled (Table 7). (guidelines 72-3(a), (b),
and (c); MRID 43107201, 43107202, and 43107203)

Conclusion

       Estuarine/marine organisms acute toxicity studies, 72-3(a),
(b),  and (c),  have not been submitted for Dowicil®75.   If the
relationship between Dowicil®75 and Dowicil®150 for estuarine
organisms is analogous to that for freshwater organisms, it can be
assumed the former is more toxic to estuarine organisms than is the
latter.  Therefore, the toxicity to these organisms will likely be
underestimated using the Dowicil®150 data.   The  Agency has
required this data as confirmatory, in order to establish the toxicity
of Dowicil®75  to estuarine organisms for the secondary oil recovery
injection   waters,   metalworking   cutting   fluids,   wet   end
additives/industrial processing chemicals, and the oil recovery
drilling muds/packer fluids uses.

(3)     Terrestrial, Semi-Aquatic and Aquatic Plant Data

       Plant    testing     is    not     required     for
microbicides/microbistats  under 40 CFR Part 158.  Because
Dowicil®CTAC is a microbicide/microbistat for control of
fungi primarily, aquatic plant toxicity requirements  have not
been required.
                20

-------
b.     Ecological Effects Risk Assessment

       (1)     Risk to Terrestrial Animals

              The use patterns of Dowicil®CTAC would result in minimal
       exposure to terrestrial organisms, therefore terrestrial species are
       not  likely  to  be  impacted  by  the  use of  Dowicil®CTAC.
       Dowicil®75 and Dowicil®150 are practically nontoxic to slightly
       toxic to upland gamebirds and wild  waterfowl.

       (2)     Risk to Aquatic Animals

              Unlike agricultural  pesticides  in which  aquatic organisms
       can be exposed via runoff and/or drift,  exposure  to  nontarget
       aquatic organisms  could  be  expected through  a point source
       discharge   of  industrial  microbicides.     In   the  case  of
       Dowicil®CTAC, there are several use sites  and environmental
       conditions  where  exposure  to  aquatic  organisms is a distinct
       possibility.   Consequently, the previously mentioned Tier  Ic EECs
       (see Table  3) were  calculated in accordance with current Agency
       policy for the following use sites: secondary oil recovery injection
       waters, metalworking cutting fluids (two scenarios - soluble cutting
       oils and metal working lubricant), wet-end  additives/industrial
       processing chemicals, and oil recovery  drilling muds/packer fluids.

              Levels of Concern are criteria used to indicate potential risk
       to nontarget organisms.  The criteria indicate that a chemical, when
       used as directed, has the potential to cause undesirable effects on
       nontarget organisms.  There  are two general  categories of LOG
       (acute  and  chronic) for each  of the four nontarget animal groups
       and one category (acute)  for each of two nontarget plant groups.

              In order to determine if an LOG has been exceeded, a risk
       quotient (RQ) must be derived and  compared to the respective
       LOG.   A risk quotient is  calculated  by dividing  an appropriate
       exposure estimate (e.g., the  estimated environmental concentration)
       by an appropriate toxicity test effect level  (e.g., the LC50).  In the
       case of microbicides, when  only  an aquatic  risk assessment  is
       performed, the acute effect levels typically are the LC50 (fish) and
       the EC50 (invertebrates).  The chronic RQ is derived using a safety
       factor of 1/100 of the acute  effect level.  This safety factor enables
       the   use  of  the   previously  mentioned Tier  Ic   estimated
       environmental concentrations.
                       21

-------
                             The criteria for the  presumption  of risk as well  as  the
                      relation  of risk to LOG exceedances  for  aquatic  organisms  are
                      summarized in the following tables.  The most sensitive species was
                      selected, regardless of testing on Dowicil®150 or Dowicil®75:

             for  wet-end additives/industrial processing chemicals and oil recovery
             drilling muds/packer fluids.  The  acute LOC is exceeded for the high
             exposure scenarios for all five of the examined uses.

                    It is important to note, that the assumption of no degradation in the
             waste stream is not valid for Dowicil®CTAC because it degrades by abiotic
             hydrolysis with reported half-lives ranging from approximately l-to-3 days
             for  50 ppm concentrations to approximately 6-to-26 days  for 1,000 ppm
             concentrations.  These calculated Tier Ic EECs are likely overestimates of
             the  actual environmental concentration which would  be found  in  the
             environment.   A  higher tier  EEC  calculation  which  considers  the
             environmental  fate  and transport  properties  of Dowicil®CTAC  would
             provide   a  more   accurate  estimate   of  the   actual  environmental
             concentrations. However,  additional environmental fate  data would be
             needed in order to calculate the higher tier EEC.  Based on  the  rapid
             hydrolysis  and  the  use  sites  for   Dowicil®CTAC,  no  additional
             environmental fate date is required. And,  discharge levels are governed
             under a NPDES  permit  granted  by state  regulatory agencies and  the
             Agency.
                                    24

                    (3)     Risk to Endangered Species

                           The LOG for endangered aquatic species is exceeded when the EEC
                    value of the exposure model equals or exceeds 1/20 the LC50 values, that
                    is the risk quotient of the EEC value divided by the LC50 equals or exceeds
                    0.05.  For Dowicil®CTAC the LOCs for risk to endangered species are
                    exceeded for the high exposure scenario for all modelled uses and for the
                    typical exposure scenarios for the wet end additives/industrial processing
                    chemicals and the oil recovery drilling muds/packer fluids. This indicates
                    that  endangered aquatic species are  at risk with  both high and typical
                    exposure scenarios. As  Dowicil®CTAC will  be discharged at a number of
                    different sites, it is reasonable  to assume  that endangered species are
                    located in  some  of  these  aquatic  habitats.    Effluent  containing
                    Dowicil®CTAC should not be discharged into streams  or other waterways
                    where endangered aquatic organisms are known to reside.  The Agency
                    wants to reiterate that the toxicity levels referenced above are based on the
                    conservative assumption  of no  degradation  and Dowicil®CTAC does
                    degrade rapidly by abiotic hydrolysis.

                           The Endangered Species Protection Program is expected to become
                    final in 1995.  Limitations in the use of Dowicil®CTAC will be required
                    to protect endangered and threatened species,  but these limitations have not
                    been  defined and may be formulation specific.  EPA anticipates that a
                    consultation with the  Fish  and Wildlife Service will be conducted in
                    accordance  with  the species-based  priority approach  described  in the
                    Program.  After completion of 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 Dowicil®CTAC. 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 Dowicil®CTAC.  Appendix  B identifies the
       generic  data  requirements that the Agency reviewed  as  part of its  determination of
       reregistration eligibility of Dowicil®CTAC, and lists the submitted studies that the Agency
       found acceptable.


                                          25

-------
       The data identified in Appendix B are sufficient to allow the Agency to assess the
registered uses of Dowicil®CTAC and to determine that Dowicil®CTAC can be used
without resulting in unreasonable adverse effects to humans and the environment. The
Agency therefore finds that all products containing Dowicil®75 and Dowicil®150 as the
active ingredients are eligible for reregistration.  The reregistration of particular products
is addressed in Section V of this document.  However, the Agency remains concerned, as
discussed above, about the potential exposure and risks associated with formaldehyde in
the workplace and to  endangered species.  The Agency has notified OSHA that the
potential for exposure to formaldehyde exists from the use of Dowicil®CTAC. OSHA has
agreed to  add products containing Dowicil®CTAC to  its formaldehyde monitoring
program. The Agency is relying on OSHA's monitoring program to regulate the potential
risks to workers. The Agency is also relying on future implementation of the Endangered
Species Act to have positive  effects on exposure and risk reduction.

       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 and the data identified in Appendix B. Although the Agency
has found  that all uses of Dowicil®CTAC 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
Dowicil®CTAC,  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.     Eligibility Decision

       Based  on the reviews of the generic data for the active ingredients Dowicil®75 and
Dowicil®150,  the  Agency  has sufficient  information  on  the  health effects  of
Dowicil®CTAC and on their potential for causing adverse effects in fish and wildlife and
the environment. The Agency has determined that Dowicil®CTAC 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 products  containing Dowicil®CTAC for all uses are eligible for reregistration.

C.     Regulatory Position

       The following  is  a  summary  of  the  regulatory positions  and rationales for
Dowicil®CTAC. Where labeling revisions are imposed, specific language is set forth in
Section V of this document.
                                    26

-------
1.      Risk Mitigation to Handlers

Personal   Protective   Equipment  (PPE)  for  Handlers  (Mixer/Loader/
Applicators)

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

       a. If the Agency has no special concerns about the acute or other adverse
       effects of an active ingredient, the PPE for pesticide handlers will be 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 Agency guidelines.

       b. If the Agency has special concerns about an active ingredient due to very
       high acute toxicity or to certain other adverse effects, such as allergic
       effects  or  delayed effects (cancer,  developmental toxicity,  reproductive
       effects, etc):

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

              (2)  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.

              (3) 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 Dowicil®CTAC,
       per se,  that warrant  the establishment of active-ingredient-based PPE
       requirements other than chemical resistant gloves for open pouring of end-
       use products. This decision is based on the risk assessment which indicates
       Dowicil®CTAC is category II  for acute dermal toxicity. Therefore,  the
       Agency is requiring chemical resistant gloves for handlers engaged in open
       pouring  of end-use products containing Dowicil®75 and Dowicil®150.
                             27

-------
2.     Potential Formaldehyde Exposure Statement

       As described in Section III. B. above, available information indicates that
exposure to Dowicil®CTAC and/or formaldehyde exists for occupational workers
involved in industrial settings and for individuals in residential settings where
Dowicil®CTAC containing products may be used. However, the Agency has also
determined that the potential exposure in residential settings are minimal and that
the potential exposure for occupational workers is low and formaldehyde levels in
the workplace  are being regulated by OSHA.  The Agency notified OSHA of
Dowicil®CTAC's potential formaldehyde release and they have agreed to include
products containing Dowicil®CTAC in  their program to  monitor  for potential
formaldehyde exposure in the workplace.

3.     Aquatic Industrial Use Statement

       Based on the above (Section III) calculations, the chronic LOG is exceeded
for both  high and typical exposure model for  wet end  additives/industrial
processing chemicals and oil  recovery  drilling muds/packer fluids.   The high
exposure scenario assumes that 90% of the sites had  greater mean stream flows for
the low flow condition. This scenario also assumes that no degradation occurred
and that the application rate is the same as the receiving body of water.  Further,
assuming that degradation has occurred, there are no directions on the label that
indicate at what intervals replenishment of the product is necessary. A higher tier
EEC calculation taking into account the fate of this chemical would likely further
reduce the estimated risk.  The Agency  has determined that the appropriate risk
reduction  measure is to require NPDES  permitting for direct effluent discharges
of all end  use products.

4.     Endangered Species Statement

       The Agency has concerns about the exposure of threatened and endangered
species to Dowicil®CTAC as discussed above in the science assessment chapter
(Section III.). 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 and have enforceable county-specific  bulletins
                             28

-------
             available. Because the Agency is taking this approach for protecting endangered
             and threatened species,  it is not imposing label modifications at this time through
             the RED. 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

                    The generic data base supporting the reregistration of Dowicil®CTAC for
             the above eligible uses has been reviewed and determined  to be  substantially
             complete.   However, the Agency is requiring that the registrant perform the
             estuarine/marine  organisms acute toxicity studies, as  confirmatory  data, on
             Dowicil®75 to establish the toxicity of Dowicil®75 to estuarine/marine organisms
             for the secondary oil recovery injection waters, metalworking cutting fluids, wet
             end  additives/industrial  processing chemicals,  and the oil recovery drilling
             muds/packer fluids uses.

             2.     Labeling Requirements for Manufacturing-Use Products

                    To remain in compliance with FIFRA, manufacturing use product labeling
             must  be revised  to comply with all current EPA regulations, PR Notices and
             applicable policies.  The MP labeling must bear the following statements under
             Directions For Use:

                    "Only for formulation into an	(fill blank with Insecticide,
                    Herbicide or the  applicable  term  which describes the type of pesticide
                    uses(s)) for the  following uses(s) :	(fill in the blank only with
                    those uses that are being supported by the MP registrant)."

                    An MP registrant may,  at his/her discretion, add one of the following
                    statements to an  MP label under  "Directions For Use" to permit the
                    reformulation of  the  product for  a specific use  or  all  additional  uses
                    supported by a formulator or use group:
                                          29

-------
                    (a)     "This  product  may be used  to  formulate products for
                           specific use(s) not listed on the MP label if the formulator,
                           user group,  or grower has  complied with  U.S.  EPA
                           submission requirements  regarding  the support  of such
                           uses(s)."

                    (b)     "This product may be  used to formulate products for any
                           additional  uses(s)   not  listed  on  the  MP label if the
                           formulator, user  group or grower  has  complied  with
                           U.S.EPA submission requirements regarding the support of
                           such uses(s)."

       Personal Protective Equipment

       Handler PPE for Occupational-Use Products

       The minimum (baseline) PPE  for handlers engaged in open pouring of Dowicil®75
       and Dowicil®150 is chemical-resistant gloves.

Note to Registrants: If a product is currently labeled for both Manufacturing Use and End
Uses, the registrant must delete one set of uses in order to make it either an MP or EP.
If the registrant chooses to delete the end uses, it must follow the requirements in this MP
labeling section.  If the registrant chooses to delete the MP use (e.g., "For Manufacturing
or Formulation Only Into..."), it must follow the requirements of the EP labeling section
below. In either case, a registrant must submit  an application to register a new product
if he wishes to market a product intended for the uses deleted from the current product.

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.
                                    30

-------
       2.     Labeling Requirements for End-Use Products

       Effluent Discharge Labeling Statements

             All Dowicil®75 and Dowicil®150 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.

             "This product is toxic to fish and invertebrates. 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 pesticide 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.

       Personal Protective Equipment

             Handler PPE for Occupational-Use Products

             The minimum (baseline)  PPE  for  handlers engaged in open pouring of
       Dowicil®75 and Dowicil®150 is chemical-resistant gloves.

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 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.
                                    31

-------
       The Agency has determined that registrants may distribute and sell Dowicil®CTAC
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 preexisting  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 Dowicil®CTAC covered by this Reregistration Eligibility Decision
Document. It contains generic data requirements that apply to Dowicil®CTAC 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
                           F     Aquatic non-food industrial
                           G     Aquatic non-food residential

                               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


                                           53

-------
       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

                                                                 AND TOXIC SUBSTANCES

            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 be, 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.


                                         69

-------
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.

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.

C.     Individual Studies
                                           71

-------
       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
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

                                           72

-------
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.

b.      Data requirement addressed.  Include on the title page the  Guideline number (s) of the
specific requirement (s) addressed by the study.
                                          73

-------
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)

       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.

                                          74

-------
       - 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
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.
                                          75

-------
       •     Remove the "Supplemental Statement of Data Confidentiality Claims".

       •     Remove the "Confidential Attachment".

       •     Excise from the body of the study any information you claim as confidential,
             even if it does not fall within the scope of FIFRA §10(d)(l)(A), (B), or (C).
             Do not close up or paraphrase text remaining after this excision.

       •     Mark the fourth copy plainly on both its  cover and its title page with the phrase
             "Public Docket Material - contains no information claimed as confidential".

              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.

       SUPPLEMENTAL STATEMENT OF DATA CONFIDENTIALITY CLAIMS
       For any portion of a submitted study that is not described by FIFRA §10(d)(l)(A), (B),
or (C), but for which you claim confidential treatment on another basis, the following
information must be included within a Supplemental Statement of Data Confidentiality Claims:

       •     Identify specifically by page and line number (s) each portion of the study for
             which you claim confidentiality.

       •     Cite the reasons why the cited passage qualifies for confidential treatment.

       •     Indicate the length of time—until a specific date or event, or permanently—for
             which the information should be treated as confidential.

       •     Identify the measures taken to guard against undesired disclosure of this
             information.

       •     Describe the extent to which the information has been disclosed, and what
             precautions have been taken in connection with those disclosures.

       •     Enclose copies of any pertinent determinations of confidentiality made by EPA,
             other Federal agencies, of courts concerning this information.

       •     If you assert that disclosure of this information would be likely to result in
             substantial harmful effects to you, describe those harmful effects  and explain
             why they should be viewed as substantial.

       •     If you assert that the information in voluntarily submitted, indicate whether you
             believe disclosure of this information might tend to lessen the availability to
             EPA of similar information in the future, and if so, how.

          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 Program's policy 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(i). 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 of 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 or 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 good 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 158.1/5.  The lower  certified limit is used as the enforceable lower limit for the product
composition according to  FIFRA section 12(a)(l)(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 product composition because the nominal concentration would
be the amount of active ingredient typically found in the product.

       It is important 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


                                         87

-------
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 or section 12(a)(l)(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 concentration 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. Copies 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 provide certified limits for each active, inert ingredient, impurities of toxicological
significance (i.e., upper limit(s) only) 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  control 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.

       (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.

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.

                                           95

-------
Call-In Response Form. Deletion of a use(s) and the low volume/minor use option are not valid
options for fulfilling product specific data requirements.

       3. Request for Product Specific Data Waivers.  Waivers for product specific data are
discussed in Section 111-D of 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
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.
                                            96

-------
       Option 2, Agreement to Share in Cost to Develop Data  — Registrants may only choose
this option tor 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.

       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.
                                            97

-------
       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.

       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 aU deficiencies in the study identified by EPA.


                                            98

-------
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 Agency approves
your waiver request, you will not be required to supply the data pursuant to section 3(cj(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

             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

       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)


                                           100

-------
       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  3D 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.

       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


                                            101

-------
unreasonable adverse effects on man or the environment. This requirement continues as long as
the products are registered by the Agency.

       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,  SubpartC.

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 me Data Call-In Notice.

             Statement of Formula (EPA Form 8570-4).

       2.     I  have entered into an agreement with one or more registrants to develop data jointly
             (Cost Sharing).  I  am submitting a copy of this agreement.  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 Notice that my product is similar enough to another
             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

       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


                                          108

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

6.      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).

7.      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

                  R.E.D.   FACTS
     Pesticide
Reregistration
    Use Profile
Dowicil®CTAC
     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 undue hazards 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 3069, Dowicil®CTAC.

     Dowicil®CTAC is used as  a microbicide/microbistat for secondary oil
injection water-water treatment and as a preservative for industrial adhesives
and coatings; resin/latex/polymer emulsions; metalworking cutting fluids;
oil recovery drilling muds/packer fluids; latex(in-can) paints; specialty
industrial products; textiles/textile fibers/cordage; and wet-end
additives/industrial processing chemicals.
     The case Dowicil®CTAC contains the two active ingredients
Dowicil®75 and Dowicil®150. The active ingredient Dowicil®75 contains
both the cis-(. 53%) and the trans-(. 44%) isomers of l-(3-chloroallyl)-
3,5,7-triaza-l-azoniaadamantane chloride. The active ingredient
Dowicil®150 contains only the cis-isomer of l-(3-chloroallyl)-3,5,7-triaza-l-
azoniaadamantane chloride.
    Regulatory
        History
     A pesticide product containing Dowicil®150 was first registered in the
United States in 1964 as a microbicide/microbistat. A second registration,
for Dowicil®75, was granted in 1972 for use as a preservative for paints,
latexes,  metalworking lubricants, and other industrial  formulations to
prevent  deterioration from bacteria and fungi.

-------
Human  Health
  Assessment
     The food additive use of Dowicil®CTAC to preserve adhesives, resins,
pulp, and paperboard that contact foods is regulated by the Food and Drug
Administration (please see  21 CFR Sections 175.105, 176.1680, 176.170,
and 176.180).
     In 1987, EPA issued the Antimicrobial Data Call-In (DCI) Notice to
obtain chronic and subchronic toxicity data for Dowicil®CTAC and other
antimicrobials.  The Agency issued a second DCI under reregistration Phase
4 in March 1992, requiring the registrant to provide chemistry, toxicology,
and environmental fate data on these active ingredients to support
reregistration.

Toxicity
     In laboratory animal  studies measuring acute  toxicity, technical grade
Dowicil®CTAC has been shown to cause moderate  effects by the dermal
route, placing it in Toxicity Category II (the second-highest of four
categories) for dermal toxicity.  It has been shown to produce slight
irritation in eye and dermal irritation studies, placing it in Toxicity Category
III for eye irritation and Toxicity Category IV for skin irritation.  It is
slightly toxic  in oral toxicity studies,  placing it in Toxicity Category III for
oral toxicity.  In an acute inhalation study, Dowicil®CTAC was found to be
slightly toxic, placing it in  Toxicity Category IV. This chemical is not a
skin sensitizer based on studies using guinea pigs.
     A 90-day dermal toxicity study in rabbits established the NOEL for
systemic toxicity as 1000 mg/kg/day.
     Dowicil®CTAC was mutagenic in the in vitro Chinese hamster ovary
cell HGPRT forward mutation assay with activation, but was  nonmutagenic
without activation. It was  negative in two other mutagenicity studies.
Dietary  Exposure
     No dietary exposure  is expected from the pesticide uses of
Dowicil®CTAC since no food or feed uses are  registered.
Occupational and Residential Exposure
     Due to its low toxicity and the lack of a toxicological endpoint of
concern,  an exposure assessment was not required for Dowicil®CTAC.
However, formaldehyde is released when Dowicil®CTAC decomposes in
aqueous solution. EPA is concerned because formaldehyde has been
classified as a Group Bl "probable human carcinogen."
     The potential for exposure to Dowicil®CTAC and/or formaldehyde
exists for occupational workers involved in the industrial setting and for
individuals in the home setting.  For residential uses, the Agency has
determined that potential exposure to Dowicil®CTAC is minimal.  For
industrial uses, most workers' exposure to Dowicil®CTAC is low because of
current use patterns.  In addition, workers in industrial settings are protected
by the Occupational Safety and Health Administration's (OSHA's)
comprehensive workplace standard for formaldehyde, with a permissible

-------
Environmental
   Assessment
exposure level (PEL) of .75 ppm in the workplace. EPA has notified
OSHA of Dowicil®CTAC's potential to release formaldehyde and OSHA
has agreed to include these products in their workplace monitoring program.
     Since Dowicil®CTAC causes moderate acute dermal toxicity (Toxicity
Category II), EPA is requiring that  labels contain a statement advising
workers to wear chemical resistant gloves for open-pouring of the end-use
product.
Human  Risk Assessment
     Since Dowicil®CTAC has no food or feed uses, dietary risk is not
expected.  The chemical causes moderate acute dermal toxicity.  Therefore,
to protect applicators' skin during open pouring of end-use products, EPA is
requiring appropriate label precautions regarding use of protective clothing
(chemical resistant gloves).  Although Dowicil®CTAC releases
formaldehyde in aqueous solutions,  minimal risk is expected in residential
settings.  Occupational risks are  low due to the chemical's use pattern and
because OSHA will  monitor workers' exposure to formaldehyde  during
industrial uses of Dowicil®CTAC.  No human health risk of concern is
therefore expected.

Environmental Fate
     Dowicil®CTAC dissipates by abiotic hydrolysis. It is not persistent
and degrades rapidly under acidic conditions.  Under neutral to alkaline
conditions,  it degrades more slowly.
Ecological Effects
     Both Dowicil®75  and Dowicil®150 are practically nontoxic to slightly
toxic to birds, fish, aquatic invertebrates, and terrestrial animals.
Ecological Effects Risk Assessment
     The use patterns of Dowicil®CTAC result in minimal risk to terrestrial
organisms.  Risk to nontarget aquatic organisms can be expected through
point source discharge of industrial  microbicides.  In the case of
Dowicil®CTAC, there are several use sites and environmental conditions
where exposure to aquatic organisms is a distinct possibility.
     Based on Agency calculations using an exposure model, the chronic
level of concern (LOG) for aquatic species is exceeded in both typical and
high exposure scenarios for wet-end additives/industrial processing
chemicals and oil recovery drilling muds/packer fluids.  The acute LOG is
exceeded in high exposure scenarios for  all  five use patterns examined.
Endangered aquatic species also  are at risk  under both typical and high
exposure scenarios.
     It is important to note, however, that the  Agency's calculations likely
overestimate the actual concentrations which would be found in the
environment.  Also, discharge levels are governed by NPDES permits
granted by state regulatory agencies and EPA.  Based on its rapid hydrolysis

-------
                          and use sites, no additional environmental fate date are required for
                          Dowicil®CTAC.

         Conclusion
            For More
        Information
     EPA is requiring product-specific data including product chemistry
    efficacy data, revised Confidential Statements of Formula (CSFs), and
revised product labeling for reregistration of products containing
Dowicil®CTAC.

     The labels of all registered pesticide products containing
Dowicil®CTAC must comply with EPA's current pesticide labeling
requirements.  In addition:
     Effluent Discharge Statement - All end-use (and manufacturing use)
products that may be contained in an effluent discharged to the waters of the
U.S. or municipal sewer systems must bear the following statement:
     "This product is toxic to fish.  Do not discharge effluent containing
     this product into lakes, streams, ponds, estuaries, oceans, or other
     waters unless in accordance with requirements  of the 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 EPA."
     Handler PPE for Occupational-Use Products - The minimum
(baseline) personal  protective equipment (PPE) for handlers engaged in open
pouring of Dowicil®75 and Dowicil®150 is chemical-resistant gloves.

     The use of currently registered pesticide products containing
Dowicil®CTAC in accordance with approved  labeling will not pose
unreasonable risks or adverse effects to humans or the environment.
Therefore, all uses  of these products are eligible for reregistration.
     These Dowicil®CTAC products will be  reregistered once the required
product-specific data, revised Confidential Statements of Formula, and
revised labeling are received and accepted by EPA.

     EPA is requesting public comments on the Reregistration Eligibility
Decision (RED) document for Dowicil®CTAC during a 60-day time period,
as announced in a Notice of Availability published  in the Federal Register.
