                        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.
 Pesticides  have been grouped into use clusters and will be
 reviewed on the basis of a  ranking scheme giving higher
 priority to (1) pesticides  in clusters used on food .and feed
 crops; and T2)"pesticides produced in large volumes.

      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
     scientific reviews may be obtained from the Information
 Services Section,  Program Management and Support Division,
 (TS-757C),  EPA,  401 M St., SW, Washington,  D.C.  20460.

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

     1.  Submission of data in support of product registration;

     2.  Modification of product labels;

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

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

     5.  Modification of uses or formulation types; or

     6.  Specification of packaging limitations.

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

     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 r-j.sVs of the
pesticide's use outweigh the benefits of use, the Agency
may propose additional regulatory actions,  such as proposed
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, toxico-
logical,  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 Tables A, B,  and C of
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.

     FIFRA sec. 6(a)(2)  requires registrants to submit factual
information concerning possible unreasonable adverse effects
of a pesticide at any time that they become aware of such
information.  Registrants should notify the Agency of any
information, including interim or preliminary results of
studies, if those results suggest possible adverse effects
on man or the environment.   This requirement continues as
long as the products are registered by the Agency-

        B.  COMPOSITION OF INORGANIC ARSENIC COMPOUNDS
     Arsenic acid (H3As04) is an inorganic form of arsenic.
Arsenic exists in two oxidation or valence states, As+3
(trivalent) and As+5 (pentavalent ) .  Arsenic acid is pentavalent.
Salts of arsenic may be pentavalent arsenates or trivalent
arsenites.  Inorganic arsenic compounds (arsenicals) can be
transformed chemically between trivalent and pentavalent
inorganic forms depending upon environmental conditions.
Inorganic and organic forms (combined with carbon atoms) are
also interconverted in nature.  In animals, similar transfor-
mations occur during metabolism in the body.  Refer to
Section III.B.2. for a discussion of the metabolism of
arsenicals in animals.

     Type  of  Pesticide:   Desiccant

     Pests Controlled:   N/A

     Registered Uses:  Cotton, Okra  (seed production crop only)

     Predominant Use:  Cotton

     Formulation Types Registered:   Aqueous solutions  (end use only)

     Method(s) of Application:   Foliar spray  (single application

                    D.   REGULATORY  HISTORY

      The  principal use  of arsenic acid as a pesticide has
 been as a component of  wood preservative formulations.
 These are not addressed in this Registration Standard, but
 will be subject of a separate Registration Standard concerning
 chromated arsenicals.   The uses of  arsenic acid subject to
 this registration standard are  desiccant uses on cotton and
 okra seed crop.

     Arsenic acid has been registered as a cotton desiccant
 for  over  22  years.  In  1979, a non-food use on seed crop
 okra was  registered in  the state of Arizona.  Previously
 registered nonwood preservative uses also included use as a
 broad spectrum herbicide on Bermudagrass turf and noncrop
 areas (e.g., highway and rail rights-of-way, parking lots,
 drainage  ditchbanks).   All but the  cotton and okra uses have
 been voluntarily cancelled.

     The  Environmental  Protection Agency issued a Notice of
 Rebuttable Presumption  Against Registration  (hereafter referred
 to as Special Review) for the wood preservative and non-wood
 preservative uses of the inorganic arsenicals on October.18,
 1978  (43  FR  48267).  That notice was based on a determination
 that the  use of the inorganic arsenical pesticide products
 met  or exceeded the risk criteria for oncogenicity, mutagenicity
 and teratogenicity under 40 CFR 162.11 (these risk criteria
 are now found in 40 CFR 154.7).

     In January 1981, the Agency issued a preliminary regulatory
 determination (46 FR 13020) which proposed changes to the
 terms and conditions of  registration for the wood preservative
 uses of the inorganic arsenicals.  The non-wood preservative
products were not included in this proposed decision, but will
be the subject of a separate proposed decision in the future.

                   III.  AGENCY ASSESSMENT

                         A.  SUMMARY

    The Agency has reviewed all the data submitted to support
the registration of arsenic acid as well as a number of
pertinent studies in the open literature on arsenic acid and
certain other inorganic arsenicals (e.g., sodium arsenate,
sodium arsenite, arsenic trioxide, arsenic pentoxide).
Based on a review of these data, the Agency has determined
the following.(see Section B of this Part for more detailed
information):

    1.  Arsenic acid is acutely toxic to humans by the oral
route, as observed from its use in homicides, suicides and
poisonings.  Few animal tests have been conducted for acute
toxicity, however, and data are required on formulated products
of arsenic acid.

    2.  Inorganic arsenic compounds (including arsenic acid)
have been classified as Group A oncogens, signifying that
there is sufficient evidence of human oncogenicity.- based on
human epidemiological studies.  This conclusion is supported
by evidence of mutagenicity in numerous studies.

    Excess mortality due to lung cancer was demonstrated
in several studies among smelter workers and among workers
engaged in the production of arsenical pesticides.  Other
human epidemiology studies have demonstrated an association
between exposure to high levels of arsenic in drinking water
or in arsenic containing medicinal preparations and skin
cancer.

    An inhalation risk assessment indicates that the risks
to mixer/loaders and applicators of arsenic acid are comparable
to those that have been tolerated for the general population
in the vicinity of smelters due to arsenic in the ambient air.
At this time the Agency is unable to estimate dermal or
dietary risks from arsenic acid pesticide uses.  The EPA
Risk Assessment Forum is reevaluating the appropriate risk
model to be used for these routes of exposure to arsenic.

    3.  Arsenic has demonstrated a potential to cause terato-
genic or fetotoxic effects.  The Agency has determined,  however,
that existing animal studies on inorganic arsenicals are
inadequate for risk assessment purposes.  Therefore additional
teratogenicity tests are necessary.  The Agency issued a
Data Call-In (DCI) Notice on 4/7/86 requesting teratogenicity
data for inorganic arsenical wood preservatives.

-------
     4.  The use of arsenic acid as a desiccant on cotton in
 Texas coastal counties may affect the Attwater's  Greater
 Prairie Chicken, an endangered species.   The  chicken feeds
 in and around cotton fields from July to September and may
 ingest arsenic acid-contaminated vegetation,  seeds and insects.
 Arsenic acid has been added to the group of pesticides used
 on cotton currently being reviewed by the Office  of Endangered
 Species,  U.S. Department of Interior.  Labeling statements
 will be required on an interim basis until avian  acute toxicity
 and avian feed residue studies are received and evaluated.
                B.   PRELIMINARY RISK  ASSESSMENT.

      There__is an extensive  body of information available  on
 arsenic and~'i€s inorganic compounds  from  literature and other
 sources.   Therefore,  although  the Agency  does not have specific
 studies on arsenic  acid per se, in many cases it is not
 requiring additional  data under FIFRA.  This risk assessment
 relies  primarily on studies and documents developed for
 other Agency  purposes.  Principal among these is a final  report
 of the  Agency's Office of Health and Environmental Assessment
 (OHEA),  entitled "Health Assessment  Document for Inorganic
 Arsenic."  This and other documents  mentioned are cited in
 the Bibliography (Appendix  IV).

      1.   Acute  toxicity.  The  acute  oral  toxicity of inorganic
 arsenicals  in humans  has been  well documented over centuries
 of use  as a poison  in homicides, suicides, and from accidental
 ingestion of  drugs  and pesticides.   The pentavalent forms
 are less  toxic  than the trivalent ones? however, the symptoms
 of toxicity are the same.   The  reported oral toxicity of
 arsenic acid  in rats  is 48-100  mg/kg, however, the rat is a
 poor  model  for  toxicity in  man, since it binds arsenic in
 the body.   Man  is known to  be more sensitive than the rat
 to arsenic  poisoning  on a weight basis.

      Data on  dermal and inhalation systemic toxicity and
 skin  and  eye  irritation potential of arsenic acid are not
 available and are required  to be submitted.

      2.   Metabolism.  The in vivo metabolism of inorganic
 arsenicals  is well  understood.  The  development of new analytical
 techniques  capable  of identifying the forms of arsenic in the
body has  enabled researchers to chart the biotransformations
that occur.   In every mammalian system studied,  inorganic
arsenicals  are metabolized  from the pentavalent forms (arsenic
acid, sodium arsenate) to the trivalent arsenite form.  At
the same  time, a methylation process results in the formation
of monomethyl and particularly dimethyl arsenic compounds.
These are subsequently excreted in the urine, usually within
several days.

-------
     With  the  exception  of  rats, arsenic does not generally
 accumulate in  active  tissues of the mammalian body.   Retention
 of  arsenic in  skin, hair, and nails is regarded as an excretory
 mechanism.   Rats,  however,  bind arsenic to erythrocytes,
 which  results  in a delayed  distribution to tissues and a
 biological half-life  of  up  to 90 days.  For this reason,
 studies  using  rats as  the test species give atypical  results.
 Required testing is to be conducted with species other than
 the rat  to avoid anomalous  findings.

     3.  Carcinogenicity.   The Carcinogen Assessment  Group
 (GAG)  of the Environmental  Protection Agency has performed
 an  assessment  of the weight of evidence for carcinogenicity
 of  inorganic arsenicals.  Based on epidemiological studies
 in  humans  and  on other supportive studies and information,
 the GAG  coffe lorded  there  is  sufficient evidence that inorganic
 compounds  of arsenic  are both lung and skin carcinogens in
 humans.  According to  the Agency's draft Guidelines for
 Carcinogen Risk Assessment  (January 7, 1986) inorganic arseni-
 cals (including arsenic acid) have been classified in  Group A
 (carcinogenic  to humans).

     A large number of toxicological studies are available
 on  the oncogenicity of arsenic compounds.  The most critical
 and persuasive evidence  linking human cancer with exposure
 to  inorganic arsenicals was derived from epidemiology  studies.
 An  excess  mortality due to  lung cancer associated with exposure
 to  arsenic  was demonstrated in several studies of smelter
 workers  and among  workers engaged in the production of arsenical
 pesticides.  The increased mortality in these studies was
 related  to  occupational inhalation exposure to inorganic
 arsenicals.

     Among  the numerous available studies,  the CAG based a
 final  risk  model for occupational inhalation exposure on
 three  studies  of copper smelter workers and on an NCI series
 of  statistical analyses of  some of these same workers:

     a.  Higgins et al.  (1982)  conducted a followup study on
 smelter  workers in Anaconda, Montana,  who had previously been
 studied  by  Lee and Fraumeni in 1969.  The Higgins study contains
 data on  1800 men,  including all of the heavy exposure workers
 and 20%  of  the other workers from the Lee and Fraumeni study.
 Cumulative  exposures were estimated and information on smoking
habits was  obtained for most of the cohorts.   A statistically
 significant  increase in the number of respiratory cancers
was observed among non-smokers  in the high exposure group.
This study  is  summarized in the OHEA report,  pp.  7-104 to
 7-110.

     b.  Lee-Feldstein (1983)  surveyed 8047 smelter workers
at the same  location as Higgins et al. in Anaconda,  Montana.
This large  study followed mortality for up to 39  years among



                                  8

-------
 workers who had been employed for at least  12  months.   Workers
 were categorized into heavy,  medium and light  exposure groups
 and by length of employment.   Detailed work exposure  levels
 and work histories were available.   At all  exposure  levels,
 there was a statistically significant number of  excess respiratory
 cancers.  This study is summarized in the OHEA report,  pp.
 7-95 to 7-104.

      c.  Enterline and Marsh  (1982)  studied 2802 men who had
 worked at a Tacoma,  Washington,  smelter for a  year or  more
 between 1940 and 1964,  with observations through 1976.
 Individual exposures to airborne arsenic were  estimated
 using work histories and were correlated to levels of  arsenic
 found in urine.   A statistically significant increase  in
 respiratory cancers  was observed at  the higher exposure levels
 studied.  This" study is summarized  in the OHEA report,  pp.
 7-118 to 7-128.

      d.  Brown and Chu (1983  a,  b, c)  interpreted the  data
 of Lee-Feldstein according to a  multi-stage model of carcino-
 genesis, taking into account  exposure rate,  durations  of
 exposure,  age at initial exposure, and  time since cessation
 of exposure.   Brown  and Chu's analysis  is described in the
 OHEA report,  pp.  7-110  to 7-118.

      The CAG used the epidemiological studies  of Higgins,
 Lee-Feldstein,  and Enterline  and Marsh  and  the statistical
 analysis of Brown and Chu in  developing its  final unit risk
 estimate for inhalation oncogenic risk,  which  is described
 in the OHEA report,  pp.  7-130 to 7-135.

      Other  human  epidemiology studies have  demonstrated an
 association between  skin cancer  in non-occupational populations
 and high levels  of arsenic in drinking  water.  Persons  exposed
 to arsenicals  in  medicines have  also  been shown  to be  at
 risk.

      The Agency has  prepared  a risk model for oral exposure
 to inorganic arsenicals  based on  an epidemiology study of
 skin cancer in a  section of Taiwan with  high arsenic concen-
 trations in well  water  (Tseng et  al., 1968).  The EPA  Risk
 Assessment  Forum,  an Agency-wide  task group  charged with
 assessing risk issues,  is-currently, reevaluating this  risk
 model  for exposure via  the oral  route.   Their report is
 expected to be issued in late 1986 or early  1987.

      In  contrast  to  the  clear association between inorganic
arsenicals  and cancer in humans,  arsenic carcinogenicity in
test animals has  not been  observed in most  studies,,  A few
recent reports have  noted  positive results.   Studies in
species other than rats  have  generally  shown negative  findings.
The OHEA document  (pp.  7-77 to 7-87)  summarizes  32 studies
using animals, in which  the majority of  studies  (25) were

-------
either negative or inconclusive.  Given the extensive amount
of  information on human exposures, the Agency is not requiring
additional animal studies.

      4.  Mutagenicity.  Results from numerous mutagenic and
other genotoxic assays provide support to the carcinogenic
risk  finding.  The weight of evidence indicates that arsenate
and arsenite can interact with DNA in mammalian somatic and
germinal cells and therefore may have the potential to cause
heritable effects in humans.

      Observed positive effects in various assays have included
chromosome-breaking effects, interference with DNA repair
mechanisms, direct toxicity to mammalian gonads, and positive
effects in ^elected microbial test systems for mutagenicity.

      For example, both the pentavalent and trivalent inorganic
arsenicals have induced chromosomal aberrations in vitro in
human fibroblast cells, Syrian hamster embryo cells, and
human peripheral lymphocytes.  Results for some studies are
dose-related, and arsenites are more potent than arsenates
in the induction of chromosomal aberrations in cultured
mammalian cells.  In addition, among lymphocytes cultured
from  exposed workers (or from patients undergoing treatment)
there is suggestive evidence of chromosomal damage by arsenic
in vivo.  Furthermore, inorganic arsenic may potentiate the
effects of chromosome-damaging agents (Sram, 1976; T.-C. Lee
et al., 1986).

      Evidence of the ability of inorganic arsenic to reach
the germ cells (gonads) and produce mutagenic effects in
mammals is found in the positive results in the dominant
lethal test of Sram and Bencko (1974).

      There are no mutagenicity data gaps for arsenic acid.

      5.  Teratogenicity/Fetotoxicity-  Arsenic has been
shown to cause teratogenic/fetotoxic effects when tested in
animals by routes of exposure not typical of those expected
for humans.  When tested by routes by which human exposure
from pesticide use could be expected, animal studies have
been  negative or inadequate to demonstrate teratogenicity/
fetotoxicity-  The Agency is unable to evaluate the risks to
humans from available animal studies, and is requiring additional
teratogenicity studies.

     Sodium arsenate has been shown to produce gross malfor-
mations (terata) in hamsters, rats and mice by intravenous
and intraperitoneal routes of administration.   Increased
mortality,  increased resorptions and decreased body weights
of fetuses have also been observed in these studies.
                                10

-------
      By contrast, oral (gavage)  studies in experimental
 animals have either failed to produce gross malformations in
 offspring or have produced only  a slightly increased incidence
 and only at dosage levels that have also caused maternal
 toxicity:

      a.  In three mouse studies  by Hood et al.  using single
 oral doses of 40-100 mg/kg,  60 mg/kg,  and 120 mg/kg on days
 7-15 of gestation,  there were no teratogenic effects at lower
 dosages.  Slight effects were noted,  but only at the 120 mg/kg
 level,  at which there was increased maternal toxicity as
 well.

      b.  Kimmel and Fowler reported that administration in
 the drinking water of 2.7 and 6.5 mg/kg/day of  s.odium arsenate
 to pregnant^rSts throughout  pregnancy  produced  no effects.

      All of the oral studies cited above were incomplete or
 had deficiencies that make them  unacceptable to the Agency
 to fulfill teratogenicity data requirements.

      Intravenous,  intraperitoneal and  oral studies  using
 sodium  arsenite have yielded results almost identical to
 those  for sodium arsenate, but at somewhat lower dosage
 levels.

      Intravenous and intraperitoneal administration are not
 typical of the  human exposures likely  from pesticide use.
 Therefore,  the  Agency is  currently unable to assess the
 risks of teratogenicity/fetotoxicity likely from pesticide
 use of  arsenic  acid.   Additional  studies  by the oral route
 are required  to assess teratogenic risks.

     Arsenic  can cross the placental barrier  in humans  and
 has been incriminated in  neonatal  deaths  (Gosselin  et al.,
 1984).   Available human studies, however,  are limited to
 epidemiological studies among  female smelter  workers in Sweden,
 which showed  increased spontaneous abortions  and decreased
 mean birthweights of  offspring.  These  studies  were designed,
 however,  to study exposures  to a  variety  of diverse chemicals
 in  the  smelter,  not arsenicals alone (OHEA,  1984).   Thus  the
 effects noted in the  study cannot  be attributed to  arsenical
 exposure  per  se.

     6.   Reproductive  effects.  There are  insufficient  data to
 assess  the effects of  inorganic arsenicals  upon reproductive
 functions.  In  light of the  Agency's concern  about  possible
 teratogenic/fetotoxic  effects of arsenicals,  a  reproduction
 study also is required.

     7.  Neurotoxicity.  Arsenic is known  to  cause  neurotoxic
effects in humans, with the  expression and  severity of  effects
dependent 'upon  the route of  exposure, level of  arsenic, and
                                  1 I

-------
 duration of exposure.  Acute and subchronic exposures typically
 lead to peripheral neuropathy,  distal muscle weakness and
 loss of sensation, which may progress to paralysis and crip-
 pling.  Lower exposures and chronic exposures generally have
 a more gradual onset of similar symptoms.

      8.  Other observed effects in humans.   Other chronic
 and subchronic effects of inorganic arsenicals that have
 been observed in humans include:

      —Skin toxicity, resulting in hyperpigmentation and
        disorders such as eczema, redness, keratosis,  loss of
        nails, and swelling,  which are reversible  if exposure
        ceases.

      —ToxfBity to the blood system,  resulting in blood
        dyscrasias of various forms,  also reversible if exposure
        ceases.

      —Liver and kidney toxicity,  with jaundice,  degeneration
        of the tissues,  and  cirrhosis.

      --Pulmonary system effects,  perforation  of the nasal
        septum, and tracheal  and bronchial effects.

      9.   Dietary Exposure and Risks.   EPA cannot  at this  time
 assess the oncogenic dietary risks  associated with  pesticide
 use of arsenic acid.

      Arsenic is a constituent of rock  and mineral  formations
 in the earth's crust.   Weathering  of  rocks and minerals and
 decay of plant material appear  to  be  major sources  of  naturally
 occurring arsenic in soils.  Additional  sources of  arsenic in
 the environment are deposition  and  precipitation  of airborne
 particles from industrial operations.

      The determination  of dietary  exposure resulting from
 pesticide use is  complicated because arsenic  acid residues
 cannot be chemically  differentiated from background arsenic.
 Further,  the form and valence of arsenic is subject to change
 under environmental conditions.  Data identifying the  species
 of arsenic residues  (pentavalent or trivalent) from applied
 arsenic  acid are  not  available.  Determination of background
 soil  residue levels and  identification of the form  of  those
 residues  are central  to  the interpretation of arsenic  acid
 residues  in  food  and  feed and the risks arising from them.

      Residue data  are required, and when submitted will be
considered in  addition to the results of the oral risk model
being  considered  by the Risk Assessment Forum  (see  III.B.3).
                                12

-------
      10.   Mixer/Loader/Applicator  Exposure  and  Risks.   Mixer/
 loaders of arsenic acid are estimated  to have an  inhalation
 exposure  of 0.07  mg/hr actual  arsenic.   This level  of  exposure
 results in a lifetime  inhalation risk  of 10~4 to  10~5  to
 mixer/loaders.  This risk level approaches  that for the
 general population in  areas of high  exposure to ambient air
 levels  of arsenic,  such as smelters.   Inhalation  exposure  to
 applicators is  negligible.

      Average dermal exposure to mixer/loaders is  estimated,
 base-i on  surrogate data from other agricultural uses,  to be
 530 mg/hr.   Dermal exposure to applicators  is estimated to
 be 24 mg/hr.  These dermal exposure  figures may be  revised
 when the  results  of the required dermal  penetration study
 and glove permeability information are submitted.   Lifetime
 dermal  oncogerfic  risk  cannot be calculated at this  time.
 The risk  model  now being assessed by the Agency Risk Assess-
 ment Forum will be used when completed.

      11.   Field worker exposure and risks.  Arsenic acid is
 used as a desiccant only on seed crop okra and  machine  harvested
 cotton.   After  application,  field workers do not  enter  treated
 fields  for  4-10 days,  and then only to check the  edge of the
 field for readiness for harvesting.  Therefore  there is  no
 reasonable  expectation of post-application exposure.  The
 use is  for  cotton,  primarily in Texas/Oklahoma, and okra in
 Arizona;  the  temperature range of 105-115*F usually necessitates
 the use of  enclosed harvesters and combines that  are air-
 filtered  and  air-conditioned.  Thus exposure to harvester
 operators is  negligible.

      12.  Benefits.  Arsenic acid is used in parts  of Texas
 and Oklahoma  to desiccate  cotton in preparation for harvesting
 with a  cotton stripper.   This  method of harvest removes  a
 crop (after desiccation)  in  one sweep--but with more leaves
 and stems than  a cotton picker..  Typically about  one-third
 of  stripper acreage is  chemically treated; arsenic  acid
 accounts  for  approximately  57% of such treatment.

      For the  stripper process to function properly, thorough
 desiccation is  needed  to  allow the cotton bolls to  break
 free  readily  from the  stalk.  The entire plant, not just the
 leaves,  must be killed  to ensure that green stem  trash  and
 newly regrown tissue will not result in excessive moisture
 in  the harvested cotton.  Excessive moisture content will
 lead to deterioration of  fiber and seed quality while the
 cotton is being stored  in modules awaiting ginning.

     In Texas and Oklahoma, much of the cotton  is of a dryland
variety, with lower yields per acre than that found in  the
Mississippi Delta or in irrigated areas of Arizona  and Cali-
fornia.   Use of arsenic acid as a desiccant also permits a
short season production system.  Desiccation allows early
                                 13

-------
harvest and destruction of crop residues before most insect
reproduction, thus diminishing the opportunity for overwintering
of boll weevils and pink bollworms.  As a consequence, popu-
lations of these insects have dropped noticeably and appli-
cations of insecticides have been significantly reduced.

     Although usage has varied over time, a normal year's
usage is about 5.8 million pounds active ingredient for
application on 1.3 million acres of cotton.  This is about
10% of total U. S. cotton acreage, but about 25% of Texas
acreage and 12% of Oklahoma acreage.  A significant portion
of the Texas acreage is in the Blacklands of the central
eastern portion of the state.

     Killing frosts or paraquat may be substituted for arsenic
acid.  In the Texas and Oklahoma Plains, frosts are frequently
relied on to desiccate cotton.  There are disadvantages,_
however, in waiting for frosts to prepare cotton for stripping:
lint weight drops, lint color darkens, staple length diminishes,
and germination decreases.  Along the Texas coast and in the
Blacklands, the lateness or infrequency of frosts prevents
reliance upon nature to desiccate cotton.  Instead chemical
desiccants are used--usually arsenic acid.

     The only registered alternative to arsenic acid is
paraquat.  The efficacy of paraquat is affected by moisture;
if conditions are too moist, the chemical may not completely
kill the plant, thus permitting foliar regrowth between
treatment and harvest.  Along the Texas coast and in the
Blacklands, paraquat is less reliable because of the generally
moist conditions of those areas.  Although paraquat may
desiccate as well as arsenic acid under dry weather conditions,
it is less consistently effective than arsenic acid.  Moreover,
it is generally more expensive.


                C.  OTHER SCIENCE ASSESSMENTS

     1.  Toxicity to fish and wildlife.  Data are not available
to completely assess the toxicity of arsenic acid to birds; an
avian acute toxicity study is required.  However, based on
avian dietary studies in mallard duck and bobwhite quail,
arsenic acid can be characterized as moderately toxic to
birds.  An estimated LD-50 based on the LC-50 is 111 mg/kg
arsenic.

     Arsenic acid is slightly toxic to freshwater fish, with
an LC-50 of approximately 60 ppm, and moderately toxic to
aquatic invertebrates  (LC-50 of 6.5 ppm).  An early life
stage study for aquatic invertebrates is required to assess
the effect of continued low-level exposure to arsenic.
                                 14

-------
      2.  Endangered species.  The use of arsenic acid as a
desiccant of  cotton in coastal areas of Texas may pose a
hazard to the Attwater's prairie chicken, an endangered
species, in Victoria, Refugio and Fort Bend counties.  The
prairie chicken uses the edges of cotton fields for feeding,
not  on the cotton plants, but on field edge forbs, seeds,
grasses, and  insects.

      At use levels of 4.4 Ibs/A, the Agency estimates that
a bird could  have an average daily intake of 73 mg/kg, well
above the endangered species trigger level of 11.1 mg/kg
(1/10 the estimated LD-50 of 111 mg/kg).

      Arsenic  acid is freely soluble in water, therefore
runoff from treated fields may potentially affect endangered
aquatic species.  Using a 5% runoff factor, the expected
environmental concentration of arsenic acid in a one acre
pond would be 815 ppb, greater than 1/20 the LC-50 for aquatic
invertebrates.  There are no endangered aquatic invertebrates
in the areas  where arsenic acid is used as a desiccant;
therefore the risk is minimal.

      3.  Groundwater.  Environmental fate data to assess the
potential of  arsenic acid or its environmental degradates
to contaminate groundwater are sparse.  The few data available
indicate that the desorption constant of arsenic acid is in
the  range of  20-100, which suggests low leaching potential.
Elevated levels of arsenic have been reported in some ground-
waters underlying arsenic acid use areas in Texas.  It is
impossible to determine whether these residues result from
pesticide use or from naturally occurring arsenic.
                 D.   TOLERANCE REASSESSMENT

     A tolerance of 4.0 ppm has been established for residues
of arsenic acid (expressed as arsenic trioxide As2C>3) in
or on cottonseed (40 CFR 180.180).  No tolerances have been
established in meat, milk, fat, meat byproducts, and processed
food or feed, nor are there any Codex, Canadian, or Mexican
cotton tolerances.   The use on okra seed crop has been deter-
mined to be a nonfood use.

     1.  Residue Data.  EPA has evaluated the residue data
supporting the existing tolerance, and has determined that
the available residue data, metabolism data (both plant and
animal) and analytical methods for residue determinations
are inadequate to support the existing tolerance for arsenic
acid in cottonseed.  The residue data reviewed in support
of the tolerance include the following:
                                 15

-------
     a.  Analytical methodology for determining the levels of
     residues of arsenic acid in plants and animals.  The
     analytical methods submitted were considered to be
     inadequate since they are not capable of distinguishing
     among the forms of arsenic in plant and animal tissues.

     b. Data on the magnitude and levels of residues of arsenic
     acid in cottonseed.  These data were considered inadequate
     because of inadequate geographical distribution of test
     sites, lack of information regarding arsenic species
     present, and insufficient number of tests reflecting
     the 4-day preharvest interval.

     2.  Toxicology Data.  As discussed earlier,  there are
few experimental animal studies adequately characterizing
the subchrdnicf and chronic effects of arsenic acid,  and the
dosage levels below which these effects are not observed (the
no observed effect level or NOEL).  There is,  as noted,  a
substantial body of information on human long-term effects
of arsenic.  Therefore,  chronic feeding studies in animals
that would normally be required in support of tolerances are
not considered necessary.  Reproduction and teratology studies
are required using arsenic acid or other soluble pentavalent
arsenicals, such as sodium arsenate or arsenic pentoxide.

     The Agency has in the interim calculated a preliminary
acceptable daily intake (PADI) level from available  data on
sodium arsenate,  a pentavalent salt of arsenic acid.  The
PADI is based on non-oncogenic effects observed in chronic
feeding studies.   After review of the required reproduction
and teratogenicity studies,  an ADI will be established using
the study which would result in the most conservative  estimate.

Three chronic feeding studies for sodium arsenate are  available:

     a.  A 2-year feeding study, on dogs (Byron et al.,  1967)
     using dosage levels of 5, 25, 50, and 125 ppm (expressed
     as actual arsenic).  Effects observed at  the highest
     dosage level (125 ppm)  were increased mortality (1/6
     dogs died),  decreased body weight gain,  and" mild  anemia.
     The NOEL for this study was 50 ppm (equivalent  to 1.25
     mg/kg/day actual arsenic).

     b.  A lifetime study in rats (Kroes et al.,  1974),
     using a single dosage of 416 ppm.  Effects  observed
     were decreased body weight gain,  decreased  food consump-
     tion,  and increased erythrocyte counts in the female
     rats.   The NOEL,  which was not determined in this study,
     was therefore <416  ppm (equivalent to <20.8  mg/kg/day).
                                 16

-------
      c.   A 2-year  feeding  study on  rats  (Byron et al,  1967),
      using dosages of  31.25,  62.5,  125,  250 and  400 ppm.
      Effects  at  the 400 ppm level were increased mortality,
      decreased body weight gain and enlarged and/or thickened
      common bile ducts in  the livers of  the treated animals.
      The  NOEL for  this study was 62.5 ppm  (equivalent  to
      3.125 mg/kg/day of sodium arsenate).

 Of  the  studies on  sodium arsenate,  the dog study was selected
 for the purpose  of calculating the  PADI  because:

      —The dog study provided the lowest NOEL (i.e., dogs
 appear to be  more  sensitive than rats to sodium arsenate),

      —The rat is  not the  test species of choice .because of
 its unique ^hatacteristic  of retaining arsenic in the body
 rather than excreting it rapidly.   The results of rat  studies
 are therefore atypical and inappropriate for determination of
 a NOEL.

      3.   Provisional Acceptable Daily Intake.  The tolerance
 for arsenic acid is  expressed as arsenic trioxide (AS2O3)
 (see 40 CFR 180.180).  The NOEL from the dog study must also
 be  expressed  as  AS2O3 for  comparability with arsenic acid.

      To convert  a  dosage of 1.25 mg/kg/day of arsenic  (the
 NOEL in the dog  study) to arsenic trioxide, one must use a
 conversion factor  of 1.32:

      1.25  mg/kg/day x 1.32 = 1.65 mg/kg/day of AS2O3.

      Using  the calculated NOEL of 1.65 mg/kg/day of AS203
 and  a safety  factor of 100, the provisional ADI is

      1.65  * 100  =  0.0165 mg/kg/day of AS203.

      For an average 60 kg person,  the Maximum Permissible
 Intake or MPI is

     0.0165 mg/kg/day x 60 kg = 0.99 mg/day.

     The amount of arsenic (expressed as  the  trioxide)  that
is contributed to the average diet from use of arsenic acid
on cotton  (known as the Theoretical Maximal Residue Contribution
or TMRC) is 0.009 mg/day.   This represents 0.9% of the amount
that is permissible for a  60  kg person.
                                17

-------
               E.  REPORTED PESTICIDE INCIDENTS

     The Agency has reviewed information from its Pesticide
Incident Monitoring System (PIMS) reports from 1966-1981.
In that period of time, 28 incidents involving arsenic acid
alone were reported.  Eight of these involved use of arsenic
acid as a cotton desiccant.

     Of the eight incidents identified as relating to cotton
desiccant use, one involved a human fatality and two persons
hospitalized,, three involved cattle, and four involved crop
damage from spray drift.
                                18

-------
             IV-  REGULATORY POSITION AND RATIONALE

                    A.  REGULATORY POSITIONS

      1. Special Review.   The Agency initiated a Special
 Review for the non-wood uses of arsenic acid in 1978.   The
 Agency's preliminary determination is projected for issuance
 in 1987.  Until the conclusion of the Special Review,  all
 currently registered products will remain registered.

          Rationale;  The Agency determined in 1978 (October 18,
 1978,  43 FR 48267)  that  the inorganic arsenicals met or
 exceeded the risk criteria for Special Review on the basis of
 oncogenicity,  mutagenicity and teratogenicity/fetotoxocity
 criteria.

      2.  New uses.   No new uses for arsenic acid will  be
 approved until the  conclusion of the Special Review.

          Rationale;  In  light of the ongoing Special Review
 and the concerns  it raises about arsenic  acid,  EPA believes
 it prudent not to expand the uses or increase potential
 exposure to arsenic acid.

      3.  Restricted Use;   Arsenic acid products will be
 restricted to  use by certified applicators.

          Rationale;  The Agency has determined that arsenic
 acid products  exceed the  criteria for Restricted Use classi-
 fication stated in  40 CFR 162.ll(c)(2)(ii).   First,  arsenic
 acid is highly toxic to  humans  by the oral  route,  thus meeting
 the criterion  for restriction on an acute toxicity basis
 (§  162.11(c)(2)(ii)(A)).   Second,  arsenic has  been categorized
 as  a Class A oncogen,  thus meeting the  criterion for restriction
 on  a chronic toxicity basis  (§  162.11(c)(2)(ii)(B)).

     EPA believes that,  to minimize  the risks  to mixer/loaders
 and applicators,  use  should be  limited to persons  who  have
 been trained in proper use procedures and exposure reduction
 measures.

     4.  Groundwater Concerns; The Agency  will  not  place any
 restrictions on use of arsenic  acid products at  this time
 based upon potential  groundwater  contamination.

         Rationale:  Available data indicate  that arsenic acid
 residues have a low leaching potential.  Although  arsenic
has been detected in groundwater, the available  data do not
                                  19

-------
permit  EPA to  determine whether the  source of the  residues
was  pesticide  use,  naturally occurring arsenic  in  the soil,
or arsenic deposited  on the soil  from non-pesticidal sources.
A decision on  regulatory  action will be deferred until the
results of the soil column leaching  study and supplemental
leaching data  specified in Table  A are submitted.

      5. Reentry Requirements;  The Agency will  not impose any
reentry requirements  for  the currently registered uses of
arsenic acid [i.e., cotton and okra  (seed crop)].

         Rationale;  After spray residues of arsenic acid
have dried on  the  fields, they are not generally dislodgeable.
Moreover,  workers  do  not  enter the treated fields for 4-10
days, and only to  inspect the fields just prior to the projected
harvest date €o insure that the crop is sufficiently desiccated
for  harvest.   These workers would only be inspecting a limited
portion of treated  fields near the end of the established
preharvest intervals  (i.e., 4 and 10 days after treatment
for  cotton and okra,  respectively).  Therefore EPA has determined
that reentry intervals are not needed.

      6.  Protective  Clothing Requirements;  The Agency will
require that protective clothing be worn by mixer/loaders
and  applicators.   Product labels will be required to specify
that mixer/loaders  wear chemical  resistant protective suits,
gloves  and boots and  eye  protection.   Applicators will be
required  to wear a  protective suit.  The Agency will also
require that a special study on glove permeability be conducted.

         Rationale;  Arsenic acid end use products are toxic
and  oncogenic.  Protective clothing is necessary to minimize
exposure  during mixing, loading and application in order to
protect against acute toxicity as well as potential oncogenic
risk.   Eye  protection is  required for mixer/loaders because
the  product is  an acid.   The glove permeability study will
permit  the  Agency to evaluate dermal exposure and risks with
protective  clothing.

      7.  Endangered  Species Concerns;   The Agency will require
ail  end-use products intended for use as  a cotton desiccant
to contain  endangered species labeling to protect the Attwater's
Greater Prairie Chicken in Texas.   labeling statements will
require users  to obtain and review a bulletin on use in
areas where the Attwater's Greater Prairie Chicken is found,
and,  in those  areas, not to use arsenic acid.   The Agency
has  included arsenic acid in its cluster  of cotton pesticides.
The  addition of arsenic acid is currently being reviewed by
the  Office of Endangered  Species  (OES),  U.S.  Department of
the  Interior (USDI).  To  further evaluate the hazard to
birds,  including endangered species,  the  Agency is requiring
an avian acute toxicity study and a residue monitoring field
study on avian food items  associated with cotton fields.
                                20

-------
         Rationale;   The  referral  to  the OES, USDI, and  the
 labeling statements  are  based  upon calculations  comparing
 the  expected  environmental concentration of arsenic acid
 with estimated  avian toxicity  levels.  The Agency derived an
 estimated avian LD5Q from the  avian  dietary LC5Q study.
 From the use  rate of arsenic acid on cotton, EPA. calculated
 the  environmental concentration level on various bird feed
 items around  cotton  fields.  The  calculated expected environ-
 mental  concentration exceeds 1/10 the estimated avian LD-50,
 and  thus arsenic acid exceeds  the criterion for referral to
 OES,  USDI for an endangered species  opinion.

      The Agency is requiring actual  residue monitoring  of
 avian feed items and an  avian  LD-50  study to verify its
 theoretical calculations.  In  the interim, endangered species
 labeling wiTl be used to protect  endangered bird species
 likely  to be  found in treated  areas.

      8.   Tolerance Reassessment;  The Agency will reassess
 the  adequacy  of the  existing tolerance after required metabolism
 data and residue data have been submitted.  Current grazing/feeding
 restrictions  will remain in effect.  The Agency has required
 residue  metabolism studies on  cottonseed,  ruminants,  and
 poultry,  crop residue field trial data on cotton, and processed
 food/feed data  for cottonseed  in  the Data Call-in (DCI)
 issued on February 10, 1986.

          Rationale?   There are insufficient data to determine
 whether  a change in  the present tolerance for cottonseed is
 needed.   Available residue data have been determined to be
 inadequate and additional toxicology data are required.

      9.   Rotational Crop Label Restrictions;   The Agency
 is not at this time requiring rotational crop restrictions.
 If required data demonstrate that followup crops take up
 arsenic residues from soil,  rotational crop restrictions or
 tolerances in those crops may be necessary.

         Rationale;   The Agency lacks data at the present time
 to determine whether planting food or feed crops-in arsenic
 acid treated soils would result in illegal residues in these
 crops.  Several factors lead the Agency to believe that
 rotational crop restrictions are not necessary to prevent
 illegal residues:  (1)  Arsenic is bound to soil,  thereby
 limiting its  bioavariability in following  crops,  such that
uptake is not expected?  and (2) If there were uptake of arsenic
in rotational crops,  phytotoxicity would occur at very low
levels,  limiting the potential residues in the plant.

-------
      11.  Continuation  of  Registration:  While data gaps are
being filled,  currently registered end-use products  (EPs)
containing  arsenic  acid as the sole active ingredient may be
sold,  distributed,  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 simply because data are
missing or  are inadequate (see FIFRA sec. 3(c)(2)(B) and
3(c)(7),  unless available data indicate that use of the
product is  likely to cause unreasonable adverse effects on
the  environment.

      Issuance of this  Standard provides a mechanism for
identifying data needs.   After receipt and review of the
data,  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  arsenic acid as the sole active ingredient,

               C.  ACCEPTABLE RANGES AND LIMITS

     1.  Product Composition Standard

     To be registered or reregistered under this Standard,
manufacturing-use products (MPs) must contain arsenic acid
as the sole active ingredient.  Each MP formulation proposed
for registration must be fully described with an appropriate
certification of limits, stating maximum and minimum amounts

than 0.1%.

     2.  Acute Toxicity Limits

     The Agency will consider registration of technical grade
and manufacturing-use products containing arsenic acid provided
that the product labeling bears appropriate precautionary state-
ments for the acute toxicity category in which each product is
placed.
                                 22

-------
     3.  Use Patterns

     To be registered under this Standard, manufacturing-use

                    D.  REQUIRED LABELING

     All arsenic acid products (manufacturing and  end use)
must bear appropriate labeling as specified in 40  CFR 162.10.
Appendix II contains information on label requirements.

     No pesticide product containing arsenic acid  may be
released for shipment by the registrant after September  30,
1987,  unless the product bears an amended label which
complies with the requirements of this Standard.

     No pesticide product containing arsenic acid  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 after
September 30,  1988, unless the product bears an amended
label  which complies with the  requirements of this Standard.

    The following information must appear on the  labeling:

    1.   Ingredients Statement

         The ingredient statement for all products must
    list the  active ingredient as  "Arsenic acid"  and must
    contain a substatement which indicates the percentage
    of  "Total Arsenic (water  soluble),  expressed  as metallic"

    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 sites,
    which  are listed in Use Patterns,  Section C.3.   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.
                                23

             V.   PRODUCTS  SUBJECT  TO  THIS  STANDARD

      All  products  containing  one  or  more  of  the  pesticides
 Identified In Section II.A. are subject to certain requirements
 for  data  submission  or changes in composition, labeling or
 packaging of the product.  The applicable requirements  depend
 on whether the  product is  a manufacturing or end use  product
 and  whether the pesticide  is  the  sole  active ingredient or
 one  of  multiple active ingredients.

     Products are subject  to this  Registration Standard  as
 follows:

 A.   Manufacturing  use products containing this pesticide as
 the  sole  active ingredient are subject to:

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

      2.  The data  requirements listed  in  Tables  A  and B2

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

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

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

  Table C lists product-specific data applicable to end use
products.  The Agency has decided that, in most cases, it
will not require the submission of product-specific data for
end use products at this time.  Therefore most Registration
Standards do not contain a Table C.


                               26

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

     The data requirements listed in Table A.

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

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

     2.  If eligible for the formulator's exemption3, the
     data requirements listed in Table C.
            srz- _^_
     3.  If not eligible for the formulator's exemption, the
     data requirements listed in Table A and the data require--
     ments listed in Table C.

     4.  The labeling requirements specified for end use
     products in Section IV.

 D.  End use products containing this pesticide as  one of
 multiple active ingredients are subject to:

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

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

     Two circumstances nullify this exemption:

     1)  If you change sources of active Ingredient to an
unregistered product, formulate your own active ingredient,
or acquire your active ingredient from a firm with ownership
in common with yours, you individually lose the exemption
and become subject to the data requirements in Table A.

     2)  If no producer subject to the generic data requirements
in Table A agrees to submit the required data, all end use
producers lose the exemption, and become subject to those
data requirements.


                                27

-------
        VI.   REQUIREMENT FOR SUBMISSION OF  GENERIC DATA

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

 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 PIPRA sec.
 3(c)(2)(B)  (DCI Notice).   EPA  has decided,  however,  not  to
 require a  registrant who qualifies for the formulator's
 exemption  (PIPRA 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 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
** Registrations granted after Issuance of this Standard
will be conditioned upon submission or citation of the data
listed in this Registration Standard.

-------
 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 PIFRA 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 (PIPRA sec.  6(e)).

 C.  Wnat 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 "PIPRA 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.
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.
                                   29

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

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

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

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

     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 Agency has carefully considered the composition and
uses of pesticide products in determining that a data require-
ment applies, EPA does not anticipate that many waivers will
be granted.  A request for waiver does not extend the time-
frames for developing required data, and if your waiver
request is denied, your registration may be suspended if you
fail to submit the data.


                                  30

-------
     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.  Procedures for requesting a change in testing protocol.

     If you will generate the required data and plan to use
test procedures which deviate from (or are not specified in)
either 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
and await EPA approval, because the Agency will not ordinarily
accept as sufficient studies using unapproved protocols.
A request for protocol approval will not extend the timefrarae
for submission of the data, nor will extensions generally be
given to conduct studies due to submittal of inappropriate
protocols.


P.  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 before the 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.

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

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


                                  31

-------
or when the Agency must approve a new or modified protocol
before the study can be begun.

     A request for an extension does not extend the tlraeframe
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.


G.  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
FIFRA sec. 3*4cJ(2)(B), an existing stocks provision Is not
consistent with the Act.  Accordingly, the Agency does not
anticipate granting permission to sell or distribute existing  .
stocks of suspended product except in rare circumstances.
If you believe that your product will be suspended or cancelled
and that an existing stocks provision should be granted, you
have the burden of clearly demonstrating to EPA that granting
such permission would be consistent with the Act.  The following
information must be included in any request for an existing
stocks provision:

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

     2.  Demonstration that such a provision would be consis-
     tent with the provisions of PIPRA.
                                 32

-------
   VII.  REQUIREMENT FOR SUBMISSION OF PRODUCT-SPECIFIC DATA

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

     If you have a manufacturing use  product, these data are
listed in Table B.  If you have an end use product, the data
are listed in Table C.  As noted earlier,  the Agency has
decided that it will not routinely require product-specific
data for enchase products at this time.  Therefore, Table C -
may not be contained in this Registration Standard; if there
is no Table C, you are not required to submit the data at
this time.

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

     Failure to comply with the product-specific data require-
ments for your products will result in suspension of the
product's registration.
                                33

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

     PIPRA 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 CPR 162.10 (see Appendix II - LABELING and SUMMARY).  In
addition, labeling requirements specific to products containing
this pesticide are specified in Section IV.D of this Registra-
tion Standard.  Applications submitted in response to this
notice must include draft labeling for Agency review.

     If you fail to submit revised labeling as required,
which complies with 40 CPR 162.10 and the specific Instructions
in Section IVvD., EPA may seek to cancel or suspend the
registration of your product under PIPRA sec. 6.
                                34

-------
                           TGUIDE-1

                       GUIDE TO TABLES

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

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

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

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

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

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

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

     TGAI = Technical grade of the active Ingredient
     PAI =  Pure active ingredient
     PAIRA = Pure active ingredient, radio labeled
     TEP =  Typical end use formulation
     MP =   Manufacturing use product
     EP =   End use product
     CHOICE = Choice of several test substances on a
              case-by-case basis

Any other test substances, such as metabolites, jfill 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 CPR Part 158.  The following
letter designations are used for the given use patterns:

     A = Terrestrial, food
     B = Terrestrial, non-food
     C = Aquatic, food
     D = Aquatic, non-food
     E = Greenhouse,  food
     P = Greenhouse,  non-food
     G = Forestry
       f= Domestic outdoor
       = Indoor

-------
                           TGUIDE-2

Any other designations will be defined in a footnote to the table.
A.  Does EPA have data? (Column 4).  This column indicates one
of three answers:

     YES - EPA has data in its files that completely 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 say so.

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

5.  Bibliographic citation (Column 5).  If the Agency has
acceptable data in its files, this column lists  the identifying
number of each study.  This normally is the Master Record
Identification (MRID) number, but may be a GS number if no
MRID number has been assigned.  Refer to the Bibliography
Appendices for a complete citation of the study.

6.  Must additional data be submitted? (Column 6).  This
column Indicates 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 situation will be
explained in a footnote to the table.

7.  Time frame 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.

§158.125 Residue Chemistry - Continued


I/ It is recommended that the results of the "Nature of Residue (Metabolism)" studies in plants and animals be submitted
   and found to be acceptable by the Agency prior to the development of an acceptable Analytical Method and that both
   of these data requirements should be completed prior to completion of the crop field trials.

21 All residue data requested in this standard must be accompanied by data regarding storage duration and conditions
   of samples analyzed.  These data must be accompanied by data depicting the stability of residues of arsenic acid
   (total as well as speciated arsenic) under the conditions and for the intervals specified.

3/ Data reflecting the distribution and metabolism of [T^Aslarsenic acid in cottonseed following foliar deslccant
   treatment.  Samples must also be analyzed using (1) Method I(d) in PAM, Vol. II (A.O.A.C. 14th Ed., § 25.041-25.04?)
   to ascertain its validity for data collection and enforcement purposes, and (11) an analytical procedure capable of
   speclatlng arsenic.

V Metabolism studies utilizing ruminants and poultry.  Animals must be dosed for three days with [74As]arsenic acid
   at a concentration in the total diet which will result in sufficient residues in the tissues, milk, and eggs for
   characterization.   Animals must be sacrificed within 24 hours of the final dose (milk and eggs must be collected
   twice daily).  7^ As- residues must be characterized in muscle, fat, kidney, liver, milk, and eggs.  Samples must
   also be analyzed using (1) Method I(b) In PAM, Vol. II (A.O.A.C. 14th Ed., § 25.050-25.055) to ascertain its validity
   for data collection and enforcement purposes, and (11) an analytical procedure capable of speciating arsenic.

j)/ Validated quantitative methods which are capable of speclatlng arsenic In plant and In animal tissues must be
   submitted.

6/ Data depicting residues of total'arsenic and Individual arsenic species (expressed as As and as As2Ch)  In or on
   cottonseed harvested 4 days after a single application of the 755? SC/L at 1.5 qt./A, applied in 4 gal. water
   /acre using ground equipment.  Tests must be conducted In TX (30/0, CA (25%), and MS (11.556), which represent the
   major U.S.  cotton  production regions (Agricultural Statistics, 1984, p. 62); 1983 preliminary cotton production
   values for each state appear in parentheses.(Note: If this use on cotton is geographically restricted to Texas and
   Oklahoma,  then data from Texas only will be required.)  The treatment history of the fields for the past 5 years will
   be required.   Two  different groups of treated samples and controls will be required.  One group should  be known to
   have been  treated  with an arsenical pesticide within the past 1 to 2 years; the second group should be  known not to
   have been  treated  in the past 5 years.  Pretreatanent soil measurements of total arsenic and individual  arsenic
   species  (expressed as As and as As203) must be obtained from each test site.

§158.125 Residue Chemistry - Continued


7/ Data depicting residues of total arsenic and  Individual arsenic species (expressed as As and as As2C3) In gin
   trash, meal, hulls, crude and  refined oil,  and soapstock, processed from cottonseed bearing measurable, weathered
   residues.  Should residues concentrate In any of these products, appropriate food/feed additive tolerances must be
   proposed.

8/ The need for studies regarding the magnitude  of the residue in meat, milk, poultry, and eggs will be determined when
   the requirement for livestock  metabolism data has been satisfied.

9/ This data has already been requested In the arsenic acid "Data Call-in Notice"  issued 2/10/86.  The time frame for
   submission of this data is as  specified in  that Notice.

                                   GENERIC DATA REQUIREMENTS FOR ARSENIC ACID


§158.130 Environmental Fate - Continued

I/ Because of the unique chemical properties of the arsenic species a complete statement of formula will be required
   for each TEP.  This statement must Include forms, quantities, and species of arsenic present.

2/ For all metabolism, dissipation and uptake studies, methodologies should be designed such that natural soil arsenic
   may be distinguished from arsenic acid residues.

3/ Due to the non-standard nature of the data requirements to be imposed under this Registration Standard it is
   strongly recommended that protocols for each study be submitted prior to initiation of the study.

V No additional data required.  Arsenic acid (pure active ingredient) is chemically defined as a weak triprotic
   Inorganic acid.  Hydrolysis of such acids occurs as deprotonation and will occur upon mixing with water.  The pK's
   for the three protons are 2.25, 6.77> and 11.60.  Products will be the proton and the pentavalent arsenate anion
   form or a partially protonated anion depending on the system pH.

5/ No additional data required.  Due to the known photochemical characteristics of the compound no useful environ-
   mental fate information would be obtained from a photolysis study.

6/ Study should be designed as a confined dissipation study.  A minimum of three soils will be necessary to fullflll
   these requirements.  At least two of the soils used in these studies must be representative of the area of use.
   Data needed Include the form, availability, and rates of dissipation and/or occlusion of arsenic acid residues.
   Species determination of available arsenic acid residues may be necessary.
                                  i
]_/ Data required must define the form, availability, and rates of dissipation and occlusion of arsenic acid residues.
   Additionally, data are required to determine the degree of anaerobicity (Eh) of the test system.  Species
   determination of available arsenio acid residues will be necessary since arsenite (As+3) formation occurs under
   anaerobic conditions.

8/ Soil column leaching study required.  See Subdivision N §163-1 for study specifics.

 §158.130 Environmental Fate - Continued

 97 Additional study required using soils representative of the areas of arsenic acid use:

    a.   At least three soil core sites should be examined for background As levels before desiccant application;

    b.   A conservative water tracer such as chloride ion should be added to the field on the same day as the pesticide
        is applied;

    c.   All soil cores should be taken and analyzed In continuous six Inch segments until the zone of maximum leaching
        is established;

    d.   Arsenic acid residues at the zone of maximum leaching should be speclated and quantified.

10/ Data requirements reserved pending the results of an acceptable laboratory volatility study.

ll/ Establishment of preapplication soil background levels is required for Interpretation of this data.

12/ Speciatlon of available As residues will be necessary for determination of environmental fate of arsenic acid
    residues.

13/ Data requirements for combination products and tank mix uses are not being Imposed for this Standard because no
    such products or tank mix uses exist for the cotton and okra uses.

IV Data requirements are reserved pending results of aerobic soil metabolism and terrestrial field dissipation
    studies.
                                   i
157 Crops used for these studies should be representative of those that are normally rotated into arsenic acid treated
    fields.

l6/ Data required unless confined study (165-1) Indicates no uptake of arsenic acid residues.

177 Baseline or background arsenic levels in test organisms must be established prior to the addition of the test
    material.

18/ A glove permeability study is required.  The study should be conducted in accordance with ASTM 739-81 - Standard
    Test Method for Resistance of Protective Materials to Permeation by Hazardous Liquid Chemicals.  It is strongly
    suggested that a test protocol be submitted prior to initiation of this study.

197 Data is only required for aquatic and/or forestry use patterns, as specified in §158.130.

I/ Residue monitoring field study on avian food items associated with cotton fields in Texas.  Carcasses should be
   recorded when found.  Pood items tested should include grasses, forbs (such as, buttonweed, doveweed and ruellia),
   seed-producing plants and dead Insects.  Protocols must be submitted within 3 months.

2/ This study may be repaired by submission of missing data/information: dissolved oxygen and pH values during the test;
   data on negative controls; and 96-hour mortality data.  If these data cannot be supplied, a new study is required in
   order to fulfill this data requirement.

3/ Studies may be required upon receipt of avian acute oral ID50 and the Special Test (70-1 described in footnote 1).

V Testing on marine organisms is reserved pending receipt of acute freshwater fish testing results (72-1).

5/ Chronic testing on freshwater aquatic species is being required because the estimated environmental concentration in
   water exceeds 0.01 the LC50.  Only the aquatic Invertebrate life cycle test is being required because acute toxicity
   data indicate that the aquatic invertebrates are more sensitive than fish to arsenic acid.

6/ Test reserved pending outcome of the aquatic invertebrate life cycle test.

7_/ Addition of arsenic acid to the diet resulted In food aversion in the submitted study.  Either a repellency test,
   using treated diet and untreated nonpreferred food as choices, or an additional dietary study using another species
   of waterfowl must be performed.

of the registrant or distributor is required on the label.
The name and 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 CPR I62.10(d)]

     Item 4.   EPA REGISTRATION NUMBER - The registration
number assigned to the pesticide product must appear on the

                                 68

-------
                          SUMMARY-3

    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 CPR I62.10(h)(2)(1)]

    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 CPR I62.10(h)(2)(11)]

    Item 8C.   PHYSICAL OR CHEMICAL HAZARD - PLAMMABILITY
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 - PIPRA sec.  3(d)
requires that all pesticide formulations/uses be classified
for either general or restricted use.  Products classified
for restricted use may be limited to use by certified applicators
or persons under their direct supervision (or may be subject
to other restrictions that may be imposed by regulation).

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

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

     If you do not believe that your product should be classified
for restricted use, you must submit any information and
rationale with your application for reregistration.   During
the Agency's  review of your application, your proposed classi-
fication determination will be evaluated in accordance with
the provisions of ko CPR 162.11 (c).  You will be notified ol'
the Agency's  classification decision.
                                 69

-------
                          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
     CPR
         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.
                                  70

-------
                          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 CPR 162.10]
                     COLLATERAL LABELING

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

 body of other text.
  (3) Names to be used in ingredient
 statement. The name used for each in-
 gredient  shall   be  the  accepted
 common name, if there  is one, fol-
 lowed by  the  chemical  name.  The
 common name may be used alone only
 if it is well known. If no common name
 has been  established, the  chemical
 name alone shall  be used. In no case
 will the use of a trademark or proprie-
 tary name  be permitted  unless  such
 name has been accepted as a common
 name by the Administrator under the
 authority of Section 25(c)(6).
  (4) Statements of percentages.  The

 a range of values such as "22-25%." If
 the uses of the pesticide  product are
 expressed as weight of active ingredi-
 ent per unit area, a statement of the
 weight of active ingredient per  unit
 volume of the  pesticide  formulation
 shall also  appear  in  the ingredient
 statement.
  (5) Accuracy of stated  percentages.
 The percentages given  shall be as pre-
 cise as possible reflecting  good manu-
 facturing practice. If there may be un-

  (h)  Warnings  and  precautionary
 statements.  Required  warnings  and
 precautionary  statements concerning
 the  general  areas  of  lexicological
 hazard including  hazard to children,
 environmental hazard, and physical or
 chemical hazard fall into two groups;
 those required on the  front panel of
 the labeling  and  those which  may
 appear  elsewhere.  Specific  require-
 ments concerning  content, placement,
 type size, and  prominence  are  given
 below.
   (1) Required front panel statements.
 With  the  exception  of  the  child
 hazard warning statement, the text re-
 quired on the front panel of the label

 ucts meeting the criteria of Toxicity
 Category I shall bear on the  front
 panel the signal word "Danger." In ad-
 dition if the product was assigned to
 Toxicity Category I on the basis of its
 oral. Inhalation or dermal toxicity (as
 distinct from skin  and eye  local ef-
 fects) the word "Poison" shall appear
 in red on a background of distinctly
 contrasting color and the skull and
 crossbones shall appear in Immediate
 proximity to the word "poison."
  (B) Toxicity  Category II. All pesti-
 cide products meeting the criteria of
 Toxicity Category n shall bear on the
 front panel the  signal word "Warn-

 Toxicity Category m shall  bear on
 the front panel the signal word "Cau-
 tion."
  (D) Toxicity  Category IV. All pesti-
 cide products meeting the criteria of
 Toxicity Category IV shall bear on the
 front panel the signal word "Caution."
  (E) Use of signal words. Use of any
signal word(s) associated with a higher
Toxicity Category  is  not permitted
except when the Agency determines
that such labeling is necessary to pre-
vent unreasonable  adverse  effects  on
man or the environment. In no case
shall more than one human  hazard
signal word appear on the front panel
of a label.
  (ii) Child hazard warning.  Every pes-
ticide product label shall bear on the
front panel the statement "keep out of
reach  of  children."  Only  in cases
where  the likelihood of contact with
children during distribution, market-

             STORAGE INSTRUCTIONS FOR PESTICIDES

Heading:

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

Storage Instructions;

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

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

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

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

4.  Instructions on what to do if the container is damaged in
    any way, or if the pesticide J.s leaking or has been
    spilled, and precautions to minimTze 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.

           TYPE PESTICIDE;   Desiccant  (Refer also to Fungicide entry for wood
           preservatives)

           FORMULATIONS;   SC/L (15.7 Ib/gal or 75% a.i.,  75%)

           GENERAL WARNINGS AND LIMITATIONS:  RESTRICTED  USE PESTICIDE.   For retail
           sale to and use only by certified applicators  or persons under their di-
           rect supervision,  and only  for those uses covered by the certified appli-
           cator's certification.   Arsenic acid is used as  a preharvest  desiccant in
           (stripper harvested) cotton and in okra grown  for seed.   Apply on clear
           days when the  average temperature is 80 F (26.7  C)  or higher.   Do not use
           in galvanized  metal containers or spray equipment,  as highly  toxic arsine
           gas may be formed.   Avoid spray drift  to desirable  plants or  to areas and
           buildings occupied  by humans,  animals,  or poultry.   Do not graze or use
           treated plants  or gin trash for food or forage.   This pesticide is toxic
           to wildlife.  Do not apply  directly to  water or  wetlands (swamps,  bogs,
           marshes and potholes).   Do  not contaminate water by cleaning  of equipment
           or disposal of  wastes.   When mixing/loading or otherwise handling the
           concentrate wear midforearm to elbow length chemical resistant gloves,
           chemical resistant  shoes or boots,  goggles or  face  shield,  and a protec-
           tive suit which has long sleeves and long pants.  When applying the di-
           luted spray solution wear a protective  suit which has long sleeves and
           long pants,  chemical resistant gloves,  and chemical  resistant  shoes or
           boots.   The protective  suit must be worn over  normal work clothes.   When
           applying the dilute spray from an enclosed aircraft  cockpit or enclosed
           tractor cab wear an uncontaminated long sleeve shirt and long  pants.  Any
           article of clothing worn while applying product must be  cleaned before
           reusing.  Launder work  clothes separately from household articles.
           Clothing which  has  been drenched or heavily contaminated should be  dis-
           posed of in accordance  with state or local regulations.
           The use of any  pesticide in a.  manner that may  kill  or otherwise harm an
           endangered or  threatened species or adversely  modify their habitat  is a
           violation of federal laws.   The use of  this  product  is controlled  to  pre-
           vent death or  harm  to endangered or threatened species that occur  in  the
           following counties  or elsewhere in their range.   Before  using  this  pesti-
           cide in the following counties,  you must  obtain  the  Cropland Endangered
           Species Bulletin (EPA/ES-CROP).   The use  of  this  pesticide is  prohibited

IV.  BIBLIOGRAPHY APPENDICES
               92

-------
                            BIBGUIDE-1

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

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

3.   IDENTIFICATION OP 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.

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

                        BIBGUIDE-2

a.  Author.  Whenever the Agency could confidently  Identify
    one, 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 -

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

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

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

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

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

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

    (4)  Volume Identification (Accession Numbers).  The
         final element in the trailing parentheses
         identifies the"EPA accession number of the volume
         in which the original submission of the study
         appears.  The six-digit accession number follows
         the symbol "CDL," standing for "Company Data
         Library."  This accession number Is In turn
         followed by an alphabetic suffix which shows the
         relative position of the study within the volume.
         For example, within accession number 123456, the
         first study would be 123456-A; the second, 123456-
         B; the 26th, 123456-Z; and the 2?th, 123456-AA.
