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

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

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

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

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

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

     EPA's reassessment results in the development of a;
regulatory position, contained in this Registration Standard,

Technical Information Service (NTIS), Attn: Order Desk>,5285

on the pesticide and each of its registered uses.  See
Section IV - Regulatory Position and Rationale.  Based on its
regulatory position, EPA may prescribe a variety of steps to
be taken by registrants to maintain their registrations in
compliance with FiFRA.  These steps may include:

     1.  Submission of data in support of product registration;

     2,  Modification of product labels;

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

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

     5.  Modification of uses or formulation types; or

     6.  Specification of packaging limitations.

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

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

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

     Registrants are reminded that FIFRA sec. 6(a)(2) requires
them to submit factual information concerning possible
unreasonable adverse effects of a pesticide at any time that
they become aware of such information.  Registrants must notify
the Agency of any information, including interim or preliminary
results of studies, if that information suggests possible
adverse effects on man or the environment.  This requirement
is independent of the specific time requirements imposed by
EPA for submission of continued studies called in by the Agency
and continues as long as a product is registered under FIFRA.

                   III.  AGENCY ASSESSMENT
A.  SUMMARY

     The Agency has reviewed all of the data submitted to
support the registration of the chlorinated isocyanurates, as
we'll as open literature information relevant to these
chemicals.  Based on a review of these data, EPA has reached
the following conclusions.

     Isocyanurate related effects observed in subchronic
studies included hyperplasia of the urinary blader and calculi
in male mice and hyperplasia of the lining of the urinary
bladder in male rats.  In a chronic study in rats, toxicity
secondary to formation of calculi in the kidney and urinary
bladder was observed in the male rats during the first 12
months of dosing at 5375 ppm.  No effects were observed at
2400 ppm.  No oncogenic effects were observed in lifetime
studies in mice and rats.  The chlorinated isocyanurates do
not induce reproductive effects in rats, teratogenic effects
in rats or rabbits, and are not mutagenic.  The chlorinated
isocyanurates have low oral and dermal toxicity and high
primary eye irritation toxicity.  The chlorinated isocyanurates
are slightly toxic to birds, but are acutely toxic to fish and
invertebrates;

     There are no significant human toxicological data gaps
for the chlorinated isocyanurates; only a primary eye
irritation study is required for the trichloroisocyanurate
group.  The chronic effects from these chemicals to aquatic
organisms are not fully known, however.

     The hypochlorous acid derived from the chemical reaction
of the chlorinated isocyanurates and water has been shown to
be chronically toxic to marine and estuarine invertebrates and
fish.   A residue monitoring study is being required to measure
the exposure and risk of hypochlorous acid to aquatic
organisms.

     There are no environmental fate data gaps for the
chlorinated isocyanurates.  Available hydrolysis data and
the required residue monitoring study for hypochlorous acid
will adequately characterize the environmental fate of the
chemicals covered under this standard.

B.  KIDNEY TOXICITY ISSUE

     The original toxicological data base for the registration
of the isocyanurates was based on studies performed in
Industrial Biotest Laboratories (IBT).  Although these studies
were later invalidated, the IBT chronic rat study indicated.
that the compound produced kidney toxicity.
                             -6-

-------
     Since the public is widely exposed to isocyanurates
through their use in swimming pools, EPA presented the
information available at the time to the FIFRA Scientific
Advisory Panel (SAP) for their opinion.  At an open meeting
held in Arlington, Virginia (January 17-18, 1980), the SAP
completed a review of the health risks associated with the
use of the chlorinated isocyanurates.  (Fowler, 1980)*

     The SAP concluded that the wide exposure of these
compounds in the environment,, coupled with an inadequate data
base from early toxicity studies, were causes for concern to
the panel.  For these reasons, the SAP recommended an immediate
coordinated attempt by EPA and the chlorinated isocyanurate
industry to establish, if possible, whether these compounds
are toxic to the kidney.  In addition to the prompt initiation
of investigative procedures for the definition of hazards, the
SAP indicated that the adoption by EPA of an appropriate
posture for expeditious regulatory action, should it be
necessary, was fully warranted.  The SAP recommended that
additional contemporary assays to characterize the safety of
the chlorinated isocyanurates should be undertaken using
currently accepted protocols, including carcinogenic, mutagenic
and teratogenic assays.                                     .

     In response to these conclusions, EPA issued a Data Call-
in Notice in accordance with section 3(c)(2)(B) of FIFRA.
This notice required that the registrants of chlorinated
isocyanurates perform the animal studies recommended by the
SAP.  Reports of these studies have been received and evaluated
for this standard.

     The subchronic rat and mouse studies and the chronic rat
study reviewed in the development, of this standard provide
acceptable data for evaluating the kidney toxicity of the
chlorinated isocyanurates.  In these studies sodium
isocyanurate was administered in the animals' drinking water
at doses up to and including the .limit of solubility of the
compound (5375 ppm) at pH 7.

     In the subchronic mouse study/ the only compound-related
effect was bladder calculi in two male mice at the high dose,
associated with irritation of the bladder lining (LOEL 5375
ppm, NOEL 1792 ppm).  The subchronic rat study showed ,
hyperplasia of the lining of the urinary bladder in the males
(LOEL 1792 ppm, NOEL 896 ppm).  No effect was observed,in the
kidneys of either sex.

     The chronic rat study provided significant information on
kidney toxicity.   Compound-related gross and microscopic
lesions were found in the urinary^tract and heart, primarily
* Memo, H.W. Fowler, Advisory Report on Chlorinated
  Isocyanurates, February 15, 1980.
                             -7-

-------
in males that died during the first 12 months of the study
after receiving 5375 ppm.  Acute nephrosis and chronic
progressive nephropathy in the kidneys and inflammation,
hemorrhage and epithelial hyperplasia of the urinary bladder
in these males was considered related to calculi found grossly
in the kidney and bladder.  Lesions in the heart, inflamation
(myocarditis and endocarditis), necrosis, and vascular
mineralization were secondary to the uremia caused by urinary
tract lesions.  The LOEL for the study was 5375 ppm based on
decreased survival in males and lesions in the urinary tract
and heart; the NOEL was 2400 ppm (154 mg/kg/day).

    The solubility of sodium isocyanurate and isocyanuric acid
in water at 25°C has been established as follows:
(Nelson, 1979)*

                      mg/liter(ppm)

         pH        Sodium Cyanurate    Cyanuric Acid

        4.4              4300                3700
        7.2              8700                7400
        7.7              8100                6900
        8.6              7600                6500

     Considering that the high dose sodium cyanurate was
ingested with the drinking water at saturation for pH 7 and
excreted in .the urine at a pH in the order of 4.4 where its
solubility is considerably less, precipitation and calculi may
form in the urine.  This possibility was clearly observed in
the male rats at the high dose of the chronic study, but not
in the females.  The male rat tends to retain a portion of
urine in its bladder at urination while the female voids
entirely.  This retention favors calculi formation.   Thus,
the toxicity observed in the urinary system of the male rat
can be attributed entirely to mechanical damage from calculi.
No evidence of direct kidney toxicity was shown in these
studies.

     In conclusion, the only toxic effect demonstrated by
sodium cyanurate is the formation of "stones" in the kidneys
and urinary tract of male rats and mice fed saturated solutions
of sodium isocyanurate (5375 ppm) in their drinking water.
Kidney/urinary tract damage occurs secondary to stone formation
and is mechanical in nature.  This effect does not pose a risk
to individuals using swimming pools treated with chlorinated
isocyanurates since final residual levels in swimming pools
are required to be maintained between 1-3 ppm available
chlorine.  This level would be equivalent to 1.1-3.3 ppm
trichloroisocyanurate, the most widely used chlorinated
isocyanurate in swimming pools.

C.  SCIENCE FINDINGS

1.  Human Toxicity
     The isocyanurates have been divided into three groups for
the purposes of acute testing based on structural and, to a
lesser degree, potential/actual effects due largely to the
level of chlorination of the triazine ring.  These groups are:
(i) isocyanuric acid; (ii) the dichloroisocyanurate group
including the acid, the potassium and sodium salts, and the
dihydrated sodium salt; and (iii) trichloroisocyanuric acid.
A  seventh compound,  [mono(trichloro) tetra(monopotassium
dichloro)] penta-s-triazinetrione, contains moieties in groups
(ii) and (iii) and, accordingly, toxicology data required for
this compound can be extrapolated from data for groups (ii)
and (iii ) .
     Since the chronic effects of chlorine to humans is well
known, EPA determined that for purposes of metabolism studies
as well as subchronic, chronic, teratogenic, and mutagenic
testing, isocyanuric acid would be representative of all the
chlorinated isocyanurates.  By using the dechlorinated s-
triazinetrione as the test substance, the effects of the
triazinetrione moiety could be distinguished from those of the
chlorine.  Sodium isocyanurate was considered to be
toxicologically equivalent to isocyanuric acid and, as such,
was selected as a suitable test substance for the development
of the toxicity data reviewed under this standard.

Acute Toxicity and Irritation Studies.  The available data
indicate that the chlorinated isocyanurates have low acute
oral and dermal toxicity and high primary eye irritation
toxicity.  Acute inhalation studies are not required because
vaporization and respirable dust are not expected.  The
dichloro- and trichloroisocyanurates are very mild primary
dermal irritants and are not considered to be dermal
sensitizers.  Since the toxicity produced by sodium
isocyanurate upon subchronic and chronic testing was only
mechanical damage from calculi, primary dermal irritation and
dermal sensitization studies are not required for the
chlorinated isocyanurates.  Delayed neurotoxicity data are not
required because the chlorinated isocyanurates are not
organophosphates.  All acute effects data requirements are
satisfied with the exception of primary eye irritation studies
for the trichloroisocyanurates group.

Subchronic Studies.  In 13-week studies involving dosing of
sodium isocyanurate in the drinking water, the NOELs in rats
and mice were 896 ppm (72 mg/kg/day) and 1792 ppm (522 mg/kg/
day), respectively.  The major toxic effects-observed were
hyperplasia of the urinary bladder and calculi in 2 of 40 male
mice and: hyperplasia in the lining of the urinary bladder in
the male? rats.  A subchronic oral study in a nonrodent species
is not required due to the similarity between the metabolism
                             -9-

-------
of sodium isocyanurate in rats and dogs.  Subchronic"dermal
(both 21- and 90-day) studies are not required because of  the
lack of toxicity observed in subchronic oral  (drinking water)
studies at doses far above use concentrations.  Subchronic
inhalation and neurotoxicity studies are not  required for  the
reasons given under the associated acute topics.  All
subchronic testing data requirements have been met.

Chironic Studies.  The LOEL in rats was 5375 ppra (371 mg/kg/day
for males) based on decreased survival and lesions  in the
heart and urinary tract of males dosed in the drinking water
for 2 years; the NOEL was 2400 ppm (154/mg/kg/day).  Oncogenic
effects were not noted at any dose in the 2-year rat study or
in a 104-week mouse study involving dosing at up to 5375 ppm
(1523 or 1582 mg/kg/day for males and females, respectively)
in the drinking water.  Note that 5375 ppm was reported to be
the limit of water solubility for sodium isocyanurate.  A
chronic oral study in a nonrodent species is  not required due
to the similarity between the metabolism of sodium  isocyanurate
in rats and dogs.  A three-generation rat reproductive study
indicated a NOEL of 5375 for both reproductive and offspring
effects; the LOEL and NOEL for adult toxicity were 5375 ppm
and 1200 ppm, respectively.  The chronic toxicity of the
chlorinated ispcyanurates is adequately understood.
No additional chronic testing is required.

Teratogenicity Testing.  The NOEL for both maternal and fetal
toxicity was >5 g/kg/day in rats.  In rabbits, sodium
isocyanurate was not teratogenic; the NOELs for maternal and
fetal toxicity were 50 mg/kg/day and 200 mg/kg/day,
respectively.  These studies are adequate; no additional
teratology studies are required.

Mutagenicity Testing^  Sodium isocyanurate is not mutagenic as
determined by studies designed to detect the  potential to
induce gene mutation, structural chromosomal  aberrations,  or
altered sister chromatid exchange frequency.  .These studies
are adequate; no additional mutagenicity studies are required.

Special.Studies.  Metabolism studies in both  the rat and dog,
following administration of [14C]sodium isocyanurate by the
oral and intravenous routes, demonstrated rapid absorption,
distribution, and excretion of unmetabolized  isocyanurate.
Elimination half-lives in rats were 32-43 minutes following
5 mg/kg/ I.V. or oral administration and 122-148 minutes after
oral dosing at 500 mg/kg.  At the 5 mg/kg dose, excretion was
largely via the urine with generally <5% via  the feces.  At
the 500 mg/kg oral dose, 55-70%  (rats) or 27-86% (dogs) was
excreted in the feces and the remainder in the urine.
Radioactivity in tissues was less than or near the sensitivity
of the method regardless of dose regimen.  These studies
adequately elucidate the absorption, metabolism, and excretion
:of the chlorinated isocyanurates.  No additional metabolism
studies are required.
                             -10-

-------
2.  Ecological Effects

     Because of its known chronic effects to aquatic organisms,
chlorine is considered to be of greater toxicological
significance than the triazine moiety.  Based on available
mammalian metabolism and oral and dermal toxicity studies, the
unsubstituted triazine ring is essentially nontoxic and rapidly
excreted in an intact form.  It is, therefore, unlikely to
accumulate in mammals.  Similiarly, EPA does not expect
accumulation to occur in fish or aquatic organisms, both due
to the fairly high water solubility of the unsubstituted ring
(ca. 2000 ppm) and because rapid excretion is also expected to
occur in fish and aquatic organisms.  No ecological effects
data are required for the triazine moiety.

     To determine the effect of hypochlorous acid on aquatic
organisms, trichloroisocyanuric acid  (trichloro-s-
triazinetrione) was selected by EPA as the single test
substance to be used to represent all registered chlorinated
isocyanurates.  Since this compound provides the highest
percentage available chlorine, it was considered to be the
most toxic chlorinated isocyanurate to aquatic organisms.

     Sufficient data are available to determine that
trichloroisocyanuric acid is only slightly toxic to birds
(LDso to bobwhite quail 1674 mg/kg).  Acceptable subacute
dietary toxicity studies on bobwhite quail and mallard ducks
indicate that trichloroisocyanuric acid is practically nontoxic
to upland gamebirds (LCsg = 7235 ppm and >10,000 ppm,
respectively).  An avian hazard is not indicated by these
studies; no additional avian toxicity data are required.

     Sufficient data are available to demonstrate that
trichloroisocyanuric acid is highly toxic to fish; the LCso
is 0.33-0.37 ppm to rainbow trout and 0.20 ppm to bluegill
sunfish.  Trichloroisocyanuric acid is highly toxic to
freshwater invertebrates (LC$Q to Daphnia magna is 0.19-0.8
ppm).  Acute LCso studies utilizing a chlorinated isocyanurate
are not available for estuarine and marine organisms.  However,
EPA believes that the toxicity of chlorinated isocyanurates is
due to the hypochlorous acid liberated in aqueous solution.
Therefore, numerous studies presented in the Ambient Water
Quality Criteria for Chlorine satisfy this requirement.
LC5QS ranged from 0.02 ppm (rainbow trout) to 0.09 ppm (shrimp)
chlorine in numerous marine and estuarine organisms (fish,
crustaceans, gastropods); this is considered highly toxic.

     Hypochlorous acid is also considered to be highly
chronically toxic to marine and estuarine invertebrates and
fish.  Water concentrations of 0.003-0.085 ppm hypochlorous
acid caused reduction in oyster shell deposition and altered
blood characteristics in fish.  A 30-day American oyster study
revealed a maximum^ allowable toxic concentration (MATC) of
0.11-0.4 ppm hypochlorous acid.  A 21-day MATC ranged.from
                             -11-

-------
0.11 ppm to 0.23 ppm for fathead minnow.  The LC5Q for
trichloroisocyanuric acid was 0.08-0.37 ppm in rainbow trout.

    . EPA does not have adequate data to.completely assess the
chronic effects of the hypochlorous acid liberated from the
chlorinated isocyanurates to aquatic organisms or to endangered
species.  Therefore, a residue monitoring study is.being
required for hypochlorous acid to determine the exposure and
risk to aquatic organisms from the aquatic non-food uses of
these chemicals.  If toxic concentrations of hypochlorous acid
are detected in effluent water, additional data will be
required to determine the effects on growth and development
(life cycle studies) of aquatic organisms.

     Honey bee exposure is not expected to result from the
registered uses .of the chlorinated isocyanurates and nontarget
insect studies will not be required.

3.  Environmental Fate

     Acceptable hydrolysis data are available for sodium
cyanurate which is representative of all the chlorinated
isocyanurates.  Based on the lack of toxicological or
ecological problems associated with the triazine moiety and
the requirement for residue monitoring studies to measure
hypochlorous acid activity in the aquatic environment, no
additional environmental fate data will be required for the
chlorinated isocyanurates.

     Based on the available data, there are no apparent human
exposure, groundwater, reentry, or drift issues.

D.   TOLERANCE REASSESSMENT

     No tolerances have been established for the chlorinated
isocyanurates.  Therefore, an ADI is not required and a
tolerance reassessment is not necessary.

     industrial uses of the chlorinated isocyanurates in
agricultural premises (including dairy milk farm equipment) ,
in .food/feed handling establishments as sanitizing solutions
on food processing equipment and utensils, and on other food-
contact articles are regulated by the Food and Drug
Administration (FDA) according to 21 CFR 178.1010(b)(2) and
(c)(2).  This regulation stipulates that aqueous solutions
containing dichloroisocyanuric acid, trichloroisocyanuric
acid, or the sodium or potassium salts of these acids, with
or without the bromides of potassium, sodium or calcium will
not provide more than 100 ppm of available halogen determined
as available chlorine.

   .  The provisions of the Federal Food, Drug, and Cosmetic
Act (Section 402) require the establishment of or exemption
from a tolerance for the use of chlorinated isocyanurate
                             -12-

-------
formulations as poultry drinking water sanitizers and as egg
sanitizers.  However, based on the lack of mammalian metabolism
and oral and dermal toxicity demonstrated by the chlorinated
isocyanurates in the studies reviewed under this standard,  EPA
will be willing to consider a request for an exemption from
the requirements of a tolerance for these uses.

     Agricultural uses of the chlorinated isocyanurates for
the commercial treatment of eggs for human consumption are
also regulated under the United states Department of
Agriculture (USDA) egg grading and egg products inspection
programs.  USDA requires that to be accepted under these
programs, all formulations must be in compliance with 21 CFR
178.1010 as sanitizing solutions for food contact surfaces.

E.  SUMMARY OF DATA GAPS

     The Agency has identified data necessary to evaluate the
environmental and human risks associated with the use of the
chlorinated isocyanurates and their salts.  These data must
be developed in order to maintain registrations of products
or register new products containing these chemicals.  The
following table summarizes the data gaps, including product
chemistry information.  Please note that this is only a
summary and details can be obtained by referring to Table A.

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

     Based on a review and evaluation of all available data on
the chorinated isocyanurates and their salts, the Agency has
made the following determinations.  Refer to Section IV.D for
specific language for label revisions.

1.  The Agency will not place the chlorinated isocyanurates
into Special Review.

Rationale ;  The chlorinated isocyanurates do not exceed the
risk criteria for adverse effects in 40 CFR, Section 154.7.
Available data indicate that the chlorinated isocyanurates
do not pose a risk of serious acute injury to humans, avian
species and aquatic organisms.  Because animal effects were
limited to hyperplasia of the urinary blader and calculi in
male mice and hyperplasia of the lining of the urinary bladder
in male rats at doses near the limit of their solubility,
these chemicals appear to produce no risk to humans.

2.  The Agency has determined that the present precautionary
statements for persons handling or applying the chlorinated
isocyanurates are sufficient for the labels of manufacturing-
use products.

Rationale ;  Available data indicate that the chlorinated
isocyanurates cause low acute oral and dermal toxicity
(Category III and IV)  and high primary eye irritation toxicity
(Category I).  The labeling of these product contain
statements, including the signal word "Danger" because of the
eye effects, that provide precautionary measures to ensure
safe handling of the pesticide products and provide the user
with first aid instructions.

3.  The Agency has determined that nontarget insect studies
are not required.

Rationale ;  Exposure to nontarget insect species is not
expected to result from the registered uses of the chlorinated
isocyanurates.  Therefore, honey bee testing is not required.

4.  The Agency will not impose a special label advisory
statement for endangered species at this time.

Rationale ;  Because the chlorine^released from the chlorinated
isocyanurates is so volatile, the Agency does not expect
exposure to endangered species from the registered patterns of
use or from accidental spills.  However, residue monitoring
studies are being required to determine if hypochlorous acid
residues resulting from the use of these chemicals may reach
surface water.
                             -14-

-------
     If the estimated environmental concentrations of chlorine
residues resulting from the use of these chemicals exceed the
endangered species trigger for aquatic species (1/10 of the
LCso)? an Office of Endangered Species opinion will be
requested.

5.  The Agency will not require the submission of
microbiological efficacy data in support of the antimicrobial
uses of the chlorinated isocyanurates.

Rationale;  EPA has data in its files which adequately
demonstrate the efficacy of hypochlorous acid.  Therefore, no
additional microbiological efficacy data will be required.

6.  The Agency is requiring the establishment of or exemption
from a tolerance for the use of chlorinated isocyanurate
formulations as poultry drinking water sanitizers and as egg
sanitizers.  If such a tolerance or exemption from a tolerance
is not proposed within 6 months from the date of issuance of
this standard, these uses will be cancelled.

Rationale;  No tolerances have been established for the
chlorinated isocyanurates as poultry drinking water sanitizers
or as egg sanitizers and residue data do not exist to support
these uses which may result in isocyanurate residues in eggs
and poultry.  However, based on the lack of mammalian
metabolism and oral and dermal toxicity demonstrated by the
chlorinated isocyanurates, EPA will be willing to consider a
request for an exemption of a tolerance for these uses.

7.  While data gaps are being filled, currently registered
manufacturing-use products containing chlorinated
isocyanurate may be sold, distributed, formulated and used,
subject to the terms and conditions specified in this
standard.  Registrants must provide or agree to develop
additional data, as specified in the Data Appendices, in
order to maintain existing registrations.

Rationale;  Under FIFRA, the Agency does not normally cancel
or withhold registration for previously registered use
patterns simply because data are missing or are inadequate
[see FIFRA sec. 3(c)(2)(B) and 3(C)(7)J.  Issuance of this
standard provides a mechanism for identifying data needs
which then will be required to be submitted to maintain the
registration of pesticide products containing chlorinated
isocyanurate.  These data will be reviewed and evaluated,
after which the Agency will determine if additional
regulatory changes are necessary.

 B.  CRITERIA FOR REGISTRATION

    To be  registered  or  reregistered  under  this  standard,
 products  must contain a chlorinated  ispcyanurate as the sole
 active  ingredient, bear required  labeling,  and  conform to the
.product composition, acute  toxicity  limits,  and use pattern
 requirements listed  in  this  section.

 C.  ACCEPTABLE RANGES AND LIMITS

     1.   Product Composition Standard

     To be  registered or reregistered  under  this standard,
 manufacturing-use products  (MUPs) must contain  one  of  the six
 chlorinated isocyanurates described  in Section  II (A)  as  the
 sole active ingredient.  Each  MUP formulation proposed, for
 registration must be fully  described with  an appropriate
 certification of limits, stating maximum and minimum amounts
 of  the  active ingredient and inert  ingredients  which are
 present in  products, as well as impurities  found at greater
 than 0.1%.

     2.   Acute Toxicity Limits

     The  Agency will consider  registration  of technical grade
 and manufacturing-use products containing  chlorinated
 isocyanurates provided  that  the product labeling bears
 appropriate precautionary statements for the acute  toxicity
 category  in which each  product is placed.         :

     3.   Use Patterns

     To be  registered under  this  standard, manufacturing-use
 products  may be labeled for  formulation into end-use products
 intended  for indoor  and aquatic non-food use patterns  only.
 The Index to Pesticide  Chemicals^/  lists all registered uses
 and sites,  as well as approved maximum application  rates  and
 frequencies.

 D.  LABELING

     All  manufacturing-use products must bear appropriate
 labeling  as specified in 40  CFR162.10.  Appendix II contains
 information on label requirements.

     No pesticide product containing a chlorinated  isocyanurate
 may be released for  shipment by the  registrant  after 12 months
 from the  date of issuance of this standard  unless the  product
 bears an  amended label  which complies  with  the  requirements of
 this standard.
 Z/ The  Index  to Pesticide  Chemicals may  be  obtained  from the
 National Technical  Information  Service  (NTIS),  Attn:  Order  Desk,
 5285 Port  Royal Road,  Springfield, VA 22161  (tel :  703/487-4650)
                              -16-

-------
     No pesticide product containing a chlorinated isocyanurate
may be distributed, sold, offered for sale, held for sale,
shipped, delivered for shipment, or received and (having so
received) delivered or offered to be delivered by any person
in channels of trade after 24 months from the date of issuance
of this standard unless the product bears an amended label
which complies with the requirements of this standard.

In addition to the above, the following information must appear
on the labeling:

     1.  Ingredients Statement

          The ingredient statement for manufacturing-use
     products must list the active ingredient as:

           Dichloro-s-triazinetrione;  or

           Potassium dichloro-s-triazinetrione;  or

           Sodium dichloro-s-triazinetrione; or

           Trichloro-s-triazinetrione; or

           Penta-s-triazinetrione; or

           Sodium dichloro-s-triazinetrione dihydrate.

     2.  Use Pattern Statements

          All manufacturing-use products must state that they
     are intended for formulation into end-use products for
     acceptable use patterns.  Labeling must specify site
     categories which are listed in the Index to Pesticide
     Chemicals.  However, no use may be included on the label
     where the registrant fails to agree to comply with the
     data requirements in TABLE A for that use pattern.

     3.  Precautionary Statements For Manufacturing-Use
         Products'

         a.  Labels for manufacturing-use products containing
             chlorinated isocyanurates must bear statements
             reflecting the acute eye irritation potential
             (Category I) for these chemicals.  Required
             precautionary statements associated with this
             category are specified in 40 CFR 162.10.

         b.  The signal word "Danger"  is required on the front
             panel of all manufacturing-use labels.
                             -17-

-------
c.  The following environmental hazard statement must
    appear on all manufacturing-use labels:

      This pesticide is toxic to fish. Do not
      discharge effluent containing this product into
      lakes, streams, ponds, estuaries, oceans, or
      public waters unless this product is
      specifically identified and addressed in an
      NPDES permit.  Do not discharge effluent
      containing this product to sewer systems without
      previously notifying the sewage treatment plant
      authority.  For guidance contact your State
      Water Board or Regional Office of the EPA.
                    -18-

-------
            V.  PRODUCTS SUBJECT TO THIS STANDARD
     All manufacturing-use products containing one of the
chlorinated isocyanurates identified in Section II.A. are
subject to certain requirements for data submission or changes
in composition, labeling or packaging of the product.  Products
are subject to the following requirements:

     1.  The restrictions (if any) upon use, composition, or
     packaging listed in Section IV, if they pertain to the
     manufacturing use product.

     2.  The data requirements listed in Tables A and B3/

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

     4.  Administrative requirements (application forms,
     Confidential Statement of Formula, data compensation
     provisions) associated with reregistration.

Refer to Section IX for specific submission requirements and
timeframes.


3/ Data requirements are listed in the two Tables in Appendix
T of this Registration Standard.  The Guide to Tables in that
Appendix explains how to read the Tables.

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

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

     Two circumstances nullify this exemption:

     1)  If you change sources of active ingredient to an
unregistered product, formulate your own active ingredient,
or acquire your active ingredient from a firm with ownership
in common with yours, you individually lose the exemption and
become subject to the data requirements in Table A.
     2)  If no producer subject to the generic data
requirements in Table A agrees to submit the required dat;
all previously eligible producers lose the exemption, and
become subject to those data requirements.
                             -19-

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

A.  What are generic data?

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

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

B.  Who must submit generic data?

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

     If you are granted a generic data exemption, you rely on
the efforts of other persons to provide the Agency with the
required data.  If the registrants who have committed to
generate and submit the required data fail to take appropriate
steps to meet the requirements or are no longer in compliance
with this data requirements notice, the Agency will consider
that both they and you are not in compliance and will normally
initiate proceedings to suspend the registrations of both your
product(s) and their product(s) unless you commit to submit
and submit the required data in the specified timeframe.  In
such cases, the Agency generally will not grant a time
extension for submitting the data.
4/ Registrations granted after issuance of this standard will
be conditioned upon submission or citation of the data listed
in this Registration Standard.
                             -20-

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

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

C.  What generic data must be submitted?

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

D.  How to comply with PCI requirements.

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

     1.  You will submit the data yourself.

     2.  You have entered into an agreement with one or more
registrants to jointly develop (or share in the cost of
developing) the data, but will not be submitting the data
yourself.  If you use this method, you must state who will
submit the data on which you will rely.  You must also provide
EPA with documentary evidence that an agreement has been formed
which allows you to rely upon the data to be submitted.  'Such
evidence may be:  (1) your letter offering to join in an
agreement and the other registrant's acceptance of your offer,
(2) a written statement by the parties that an agreement
exists, or (3) a written statement by the person who will be
submitting the data that you may rely upon its submission.
                             -21-

-------
The Agency will also require adequate assurance that the person
whom you state will provide the data is taking appropriate
steps to secure it.  The agreement to produce the data need
not specify all of the terms of the final arrangement between
the parties or a mechanism to resolve the terms.

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

     a.  A list of the members of the consortium;
     b.  The name and address of the designated representative
         of the consortium, with whom EPA will correspond
         concerning the data;
     c.  Identity of the Registration Standard containing the
         data requirement;
     d.  A list of the products affected (from all members of
         the consortium); and
     e.  Identification of the specific data that the
         consortium will be generating or submitting.

     The Agency will assign a number to the consortium, which
should be used on all data submissions by the consortium.

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

     In order to qualify for this method, you must:

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

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

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

                             -22-

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

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

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

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

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

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

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

    As noted herein, these EPA Guidelines, which are referenced
in the Data Tables, are available from the National Technical
Information Service (NTIS), Attn: Order Desk, 5285 Port Royal
Road, Springfield, VA 22161 (tel: 703/487-4650).
                             -23-

-------
    Protocols approved by the Organization for Economic
Cooperation and Development (OECD) are also acceptable if the
OECD-recommended test standards conform to those specified in
the Pesticide Data Requirements regulation (Part 158.70).
Please note, however, that certain OECD standards (such as
test duration, selection of test species, and degradate
identification which are environmental fate requirements) are
less restrictive than those in the EPA Assessment Guidelines
listed above.  When using the OECD protocols, they should be
be modified as appropriate so that the data generated by the
study will satisfy the requirements of Part 158.  Any protocol
must be conducted in accordance with the Good Laboratory
Practice Regulation (48 FR 53846).  Normally, the Agency will
not extend deadlines for complying with data requirements when
the studies were not conducted in accord with acceptable
standards.  The OECD protocols are available from OECD, 1750
Pennsylvania Avenue, N.W., Washington, D.C.  20006.

F.  Procedures for requesting a change in testing protocol.

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

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

G.  Procedures for requesting extensions of time.

     If you think that you will need more time to generate
the data than is allowed by EPA's schedule, you may submit a
request for an extension of time.  Any request for a time
extension which is made as an initial response to a section
3(c)(2)(B) request notice must be submitted in writing to the
Product Manager listed at the end of this section and must be
made by the 90-day deadline for response.  Once dates have
been committed to and EPA has accepted these commitments, any
subsequent requests for a time extension must be submitted in
writing, to the Office of Compliance Monitoring at the address
given in Section IX.C.

     EPA will view failure to request an extension before the
data submission response deadline as a waiver of any future
claim that there was insufficient time to submit the data.
While EPA considers your request, you must strive to meet the
deadline for submitting the data.
                             -2.4-

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

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

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

    All data submitted in response to this Notice must comply
with EPA requirements regarding the reporting of data,
including the manner of reporting, the completeness of results,
and the adequacy of any required supporting (or raw) data,
including, but not limited to,  requirements referenced or
included in this Notice or contained in PR Notice 86-5 (issued
July 29, 1986).

I.  Existing stocks provision upon suspension or cancellation.

     The Agency has determined  that if a registration is
suspended for failure to respond to a DCI request under
FIFRAsec. 3(c)(2)(B), an existing stocks provision for
registrants is not consistent with the Act.  Accordingly, the
Agency does not anticipate granting registrants permission  to
sell or distribute existing stocks of suspended product except
in rare circumstances.  If you  believe that your product will
be suspended or cancelled and that an existing stocks provision
should be granted, you have the burden of clearly demonstrating
to EPA that granting such permission would be consistent with
the Act.  The following information must be included in any
request for an existing stocks  provision:

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

     2.  Demonstration that such a provision would be
     consistent with the provisions of FIFRA.
                             -25-

-------
   VII. REQUIREMENT FOR SUBMISSION OF PRODUCT-SPECIFIC DATA
     Under its DCI authority, EPA has determined that certain
product-specific data are required to maintain your
manufacturing-use registrations in effect.  Product-specific
data are derived from testing using a specific formulated
product, and, unlike generic data, generally support only
the registration of that product.  All such data must be
submitted by the dates specified in this Registration
Standard.  These data are listed in Table B.

     In order to comply with the product-specific data
requirements, you must follow the same procedures as for
generic data.  See Section VI.D, E, F, and G.  You should
note, however, that product chemistry data are required for
every product, and the only acceptable responses are options
VI.D.I. (submit data) or VI.D.6.(cancellation of registration)

     Failure to comply with the product-specific data
requirements for your products will result in suspension of
the product's registration.


    VIII.  REQUIREMENT FOR SUBMISSION OF REVISED LABELING
     FIFRA requires each product to be labeled with accurate,
complete and sufficient instructions and precautions,
reflecting the Agency's assessment of the data supporting the
product and its uses.  General labeling requirements are set
out in 40 CFR162.10 (see Appendix II - LABELING and SUMMARY).
In addition, labeling requirements specific to products
containing this pesticide are specified in Section IV.D of
this Registration Standard.  Applications submitted in response
to this notice must include draft labeling for Agency review.
Refer to Section IX for specific submission requirements and
timeframes.

     If you fail to submit revised labeling as required, which
complies with 40 CFR162.10 and the specific instructions in
Section IV.D., EPA may seek to cancel or suspend the
registration of your product under FIFRA sec. 6.
                             -26-

-------
                IX.   INSTRUCTIONS  FOR SUBMISSION
 A.   Manufacturing  Use  Products  (MUPs)  containing  the  subject
     pesticide  as sole  active  ingredient.

      inch paper or a mockup Of the labeling suitable  for
      storage in 8-1/2  x  11  files.  The draft  label must
      indicate  the  intended colors of the final  label, clear
      indication of the front  panel of  the  label,  and  the
      intended  type sizes of the text.

      2.   Within 9  months from receipt  of this document  you  must

-------
     3.  Within the times set forth in Table A, you must submit
to the Registration Division all generic data, unless you are
eligible for the formulator's exemption.  If for any reason
any test is delayed or aborted so that the schedule cannot be
met, immediately notify the Product Manager and the Office of
Compliance Monitoring of the problem, the reasons for the
problem, and your proposed course of action.

                           TGUIDE-1

                       GUIDE TO TABLES

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

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

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

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

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

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

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

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

3.  Use pattern (Column 3).  This column indicates the use
patterns to which the data requirement applies.  Use patterns
are the same as those given in 40 CFR Part 158.  The following
letter designations are used for the given use patterns:

     D = Aquatic, non-food
     I = Indoor

Any other designations will be defined in a footnote to the table.
                              -29-

-------
                           TGUIDE-2.

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

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

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

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

5.  Bibliographic citation (Column 5).   If .the Agency has
acceptable data in its files, this column lists the identifying
Master Record Identification (MRID) number.  Refer to the
Bibliography Appendices for a complete citation of the study.

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

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

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

§158.130 Environmental Fate - Continued

I/ The test substance for this requirement was sodium isocyanurate which is toxicologically equivalent to isocyanuric
   acid, a chemical representative of all the chlorinated isocyanurates.   Although isocyanurate acid is utilized as a
   buffer to stabilize chlorine and has no pesticidal properties per se,  it was selected as the test substance for this
   study because by using the dechlorinated s-triazetrione,  the effects of the triazinetrione moiety can be distinguished
   from those of the chlorine.
2/ The environmental fate of hypochlorous acid, formed upon  reaction with water of the chlorine portion of the
   chlorinated isocyanurates, is known.  In addition to hypochlorous acid, the triazine moiety is expected to result
   from degradation of chlorinated isocyanurates in the-aquatic environment.  Based on available mammalian metabolism
   and oral and dermal toxicity studies, the unsubstituted triazine ring is essentially nontoxic. and rapidly excreted
   in an intact form.  It is, therefore, unlikely to accumulate in mammals.  Similiarly, no accumulation in fish or
   aquatic species is expected to occur, both due to the fairly high water solubility of the unsubstituted ring
   (ca. 2000 ppm) and because rapid excretion is also expected to occur in fish and aquatic organisms.  As a result of
   the lack of toxicological or ecological problems associated with the triazine moiety, these data are not required.
V Not required because the chlorinated isocyanurates have ho soil application uses.
4/ Not required because the chlorinated isocyanurates are always applied and used in water solution.
5/ Not required because the chlorinated isocyanurates have no forestry uses.
6/ Not required because the chlorinated isocyanurates have no crop uses.

I/ Not required because there is no expected exposure from the registered patterns of use.
2/ Only one species is required.                            .        .
V Development of these data is contingent upon the results of the residue monitoring study for chlorine resulting from
   treatment with the chlorinated isocyanurates (72-7).
4/ In addition to hypochlorous acid, the triazine moiety is expected to result from degradation of chlorinated
   isocyanurates in the aquatic environment.   Based on available mammalian metabolism and oral and dermal toxicity
   studies, the unsubstituted triazine ring is essentially nontoxic and rapidly excreted in an intact form.  It is,
   therefore, unlikely to accumulate in mammals.   Similiarly,  no accumulation in fish or aquatic species is expected to
   occur, both due to the fairly high water solubility of the  unsubstituted ring (ca. 2000 ppm) and because rapid
   excretion is also expected to occur in fish and aquatic organisms.
_5/ Simulated field testing is required as follows:  Within 24  months a study monitoring chlorine in industrial effluents
   and receiving waters is required where the pesticide is used as a microbiocide in cooling towers, pulp and paper
   mills, and oil drilling operations.  Based on use information (i.e., geographical sites, amount used), the registrant
   is required to develop an acceptable protocol, within 120 days of receipt of this notice and prior to study
   initiation, to sample a representative number of the above  mentioned facilities in order to assess the release of
   chlorine into the environment with regard to the National Criteria set for this chemical.  Monitoring is required due
   to the known acute and chronic effects of hypochlorous acid on aquatic organisms and possible effects on endangered
   species.  Any protocol developed for monitoring this chemical must consider the following requirements:  (i) use of
   standard analytical methods, i.e., HPLC or MSGC, to measure chlorine, (ii) sites selected for sampling must be where
   chlorinated isocyanurates are currently being used and be representative of small and large facilities and/or volumes,
   (iii) sites selected must also be representative of (a) a range in volume of the receiving water bodies of rivers and
   (b) freshwater and estuarine ecosystems, (iv)  samples taken for analysis must be taken before treatment, after
   treatment and from receiving waters, (v) sampling should be done at regular intervals for a long enough period of
   time to account for such things as seasonal and use variations.  Actual field testing for fish and aquatic species
   will be reserved pending the results of this study.
6/ The test material for this study is trichloroisocyanurate.

                       . LABEL CONTENTS

    .40 CFR 162.10 requires that certain specific labeling
statements appear at certain locations on the label.  This
is referred to as format labeling.  Specific label items listed
below are keyed to the table at the end of this Appendix.

     Item 1.  PRODUCT NAME - The name, brand or trademark is
required to be located on the front panel, preferably centered
in the upper part of the panel.  The name of a product will
not be accepted if it is false or misleading.

   .  Item 2.  COMPANY NAME AND ADDRESS - The name and address
of'the registrant or distributor is required on the label.
The name arid address should preferably be located at.the
bottom of the front panel or at the end of the label text.

     Item 3.  NET CONTENTS - A net contents statement is
required on all labels or on the container of the pesticide.
The preferred location is the bottom of the front panel
immediately above the company name and address, or at the end
of the label text.  The net contents must be expressed in the
largest suitable unit, e.g., "1 pound 10 ounces" rather than
"26 ounces." in addition to English units, net contents may
be expressed in metric units.  [40 CFR 162.10(d)]

     Item 4.  EPA REGISTRATION NUMBER - The registration
number assigned to the pesticide product must appear on the
label, preceded by the phrase "EPA Registration No.," or "EPA
Reg. No."  The registration number must be set in type of a
size and style similar to other print on that part of the
label on which it appears and must run parallel to it.  The
registration number and the required identifying phrase must
not appear in such a manner as to suggest or imply recommendation
or endorsement of the product by .the Agency.
[40 CFR 162.10(e)}                                          .

     Item 8A.  HAZARD TO HUMANS AND DOMESTIC ANIMALS - Where a
hazard exists to humans or domestic animals, precautionary
statements are required indicating the particular hazard, the
route(s) of exposure and the precautions to be taken to avoid
accident, injury or damage.  . [40 CFR 162.10(h)(2)(i)]

     Item 8B.  ENVIRONMENTAL HAZARD - Where a hazard exists to'
non-target organisms excluding humans and domestic animals,
precautionary statements are required stating the nature of
the hazard and the appropriate precautions to avoid potential
accident, injury, or damage.  [40 CFR 162.10(h)(2)(ii)]

     Item 8C.  PHYSICAL OR CHEMICAL HAZARD - FLAMMABILITY
Precautionary'statements relating to flammability of a product
are  required to appear on the label if it meets the criteria
in the PHYS/CHEM Labeling Appendix. The requirement is
based on the results of the flashpoint determinations and
flame extension tests required to be submitted for all products.
These statements are to be located in the side/back panel
precautionary statements section, preceded by the heading
"Physical/Chemical Hazards."  Note that no signal word is
used in conjunction with the flammability statements.

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

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

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

     If you do not believe that your product should be classified
for  restricted use, you must submit any information and
rationale with your application for reregistration.   During
the Agency's review of your application,  your proposed classi-
fication determination will be evaluated in accordance with
the provisions of 40 CFR 162.ll(c).  You will be notified of
the Agency's classification decision.
                             -49-

-------
                          SUMMARY-4

     Classification Labeling Requirements

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

     1.  All uses restricted.

         a.  The statement "Restricted Use Pesticide" must
     appear at the top of the front panel of the label.  The
     statement must be set in type of the same minimum size
     as required for human hazard signal word (see table in 40
     CFR 162.10(h)(1)(iv)

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

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

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

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

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

    Item 9B.  MISUSE STATEMENT - All products must bear the
misuse statement, "It is a violation of Federal law to use
this product in a manner inconsistent with its labeling."
This statement appears at the beginning of the directions
for use,  directly beneath the heading of that section.
                             -50-

-------
                          SUMMARY-5

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

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

    Item IOC.  DIRECTIONS FOR USE - Directions for use must
be stated in terms which can be easily read and understood by
the average person likely to use or to supervise the use of
the pesticide.  When followed, directions must be adequate to
protect the public from fraud and from personal injury and to
prevent unreasonable adverse effects on the environment.
[40 CFR 162.10]
                     COLLATERAL LABELING .

    Bulletins, leaflets, circulars, brochures, data sheets,
flyers, or other written or graphic printed matter which is
referred to on the label or which is to accompany the product
are termed collateral labeling.  Such labeling may not bear
claims or representations that differ in substance from those
accepted in connection with registration of the product.  It
should be made part of the response to this notice and submitted
for review.

arsenic  calculated as  elemental ar-
senic. The active  ingredients must be
designated by the term "active ingredi-
ents" and the Inert ingredients by the
term "inert Ingredients." or the singu-
lar forms of these terms when appro-
priate. Both  terms shall be  In  the
same type size, be aligned to the same
margin and be equally prominent. The
statement "Inert Ingredients, none" is
not required for pesticides which con-
tain  100 percent  active ingredients.
Unless the ingredient statement is a

             STORAGE INSTRUCTIONS FOR PESTICIDES

Heading;

All products are required to bear specific label instructions
about storage and disposal. .Storage and disposal instructions
must be grouped together in the directions for use portion of
the label under the heading STORAGE AND DISPOSAL.  Products
intended solely for domestic, use need not include the heading
"STORAGE AND DISPOSAL."

Storage Instructions:             .

All product labels are required to have 'appropriate storage
instructions.  Specific storage instructions are not prescribed.
Each registrant must develop his own storage instructions,
considering, when applicable,  the following factors:

1.  Conditions of storage that might alter the composition or
    usefulness of the pesticide.  Examples could be temperature
    extremes, excessive moisture or humidity, heat, sunlight,
    friction, or contaminating substances or media.

2.  Physical requirements of storage which might adversely
    ciffect the container of the product .and its ability to
    continue to function properly.  Requirements might include
    positioning of the container in storage,  storage or damage
    due to stacking,  penetration of moisture, and ability to
    withstand shock or friction.

3.  Specifications for handling the pesticide container,
    including movement of container within the storage area,
    proper opening and closing procedures (particularly for
    opened containers), and measures to minimize exposure
    while opening or closing container.

4.  Instructions on what to do if the container is damaged in
    any way, or if the pesticide is leaking or has been
    sspilled, and precautions to minimize exposure if damage occurs

5.  General precautions concerning locked storage,  storage in •
    original container only, and separation of pesticides
    during storage to prevent cross-contamination of other
    pesticides, fertilizer, food, and feed.

6.  General storage instructions for household products should
    emphasize storage in original container and placement in
    locked storage areas.

                        BIBGUIDE-1

          GUIDE TO USE OF THIS BIBLIOGRAPHY

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

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

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

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

                    BIBGUIDE-2               .

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

Document Date.  When the date appears as four digits
with no question marks, the Agency took it directly
from the document.  When a four-digit date is followed
by a question mark, the bibliographer deduced the
date from evidence in the document.  When the date
appears as (19??), the Agency was unable to determine
or estimate the date of the document.

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

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

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

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

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

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