 Chlorpropham
     All pesticides sold or distributed in the United States must be
 registered by'EPA, based on scientific studies showing that they can be
 used without posing Unreasonable risks to people or the environment.
 Because of advances in scientific knowledge, the law requires that
 pesticides which were first registered before November 1, 1984, be
 reregistered to ensure that they meet today's more stringent standards.
     In evaluating pesticides for reregistration, EPA obtains ,and reviews a
 complete set of studies from pesticide producers, describing the human
 health and environmental effects of each pesticide.  The Agency develops
 any mitigation measures or regulatory controls needed to effectively reduce
 each pesticide's risks.  EPA then reregisters pesticides that can be used
 without posing unreasonable risks to human health or the environment.
  .   When a pesticide is eligible for reregi strati on, EPA explains the basis
 for its decision in a Reregi strati on Eligibility Decision (RED)  document.
 This fact sheet summarizes the information in the RED document for
 reregistration case 0271, chlorpropham.

     Chlorpropham is a herbicide and plant growth inhibitor used to
 control  mouseear chickweed in spinach and  fruiting in ginkgo trees, reduce
 Botrytis infection in Easter lilies as well as assist in their floral bud removal,
 and inhibit sprouting in stored potatoes. Formulations include emiilsifiable'
 concentrates (36%, 46.5%, and 25% active ingredient), soluble concentrates
 (49.6%, 78.5%, and 78.4% active ingredient) and a ready-to-use product
 (78.4%  active ingredient).               _
    Chlorpropham is applied by, aerosol generator, mist blower, sprayer,
 low pressure ground boom, and foaming apparatus^  Use practice

     Regulatory        Chlorpropham was registered in the United States in 1962 as a pre-
         HJStory   emergence and post-emergence herbicide and-as a plant gn. -th regulator
                     It was originally registered for use on a variety of terrestrial food crops,
                     nonfood crops, and ornamentals to control broadleaf weeds and grasses,
                   •  and sprouting in stored potatoes. The Agency published an evaluation of
                     existing data and identified data gaps in the December 1987 Guidance for
                     the Reregistration of Pesticide Products Containing Chlorpropham as the
                     Active Ingredient (NTIS #PB88-169917). This Registration Standard
                     required additional data in the areas of product chemistry, residue
                     chemistry, toxicology, ecological effects, and environmental fate. By 1990,
                     the primary registrants had dropped all nationwide uses of Chlorpropham
                     except for sprout control on post-harvest stored potatoes.  However, an
                     additional 11 registrations for use within a particular county or state
                     (registered under FIFRA Sect. 24(c)) remain today for use on spinach,
                     Easter lilies, and ginkgo trees.
                          A Data Call-in (DCI) was issued in April of 1994 requiring an
                     analytical method to detect a metabolite of Chlorpropham, 4-
                     hydroxychlorpropham-O-sulfonic acid, and a residue study to test for that
                     metabolite in meat and milk.  The Agency is considering these data
                     confirmatory to the decisions in the RED document.

Human Health    Toxicity
  Assessment         In studies using laboratory animals, Chlorpropham generally has been
                     shown to be of low acute toxicity. It is slightly toxic by the oral route and
                    has been placed in Toxicity Category III (the second lowest of four
                    categories) for this effect.  Chlorpropham is a mild eye and skin irritant, and
                    is practically non-toxic through dermal exposure.
                          A 21-day dermal study using rabbits produced skin irritation and
                    blood cell changes in both sexes.  A 60-week chronic feeding study in
                    beagle dogs resulted in reduced body weight gain, anemia, and changes in
                    thyroid function and structure. In a two-year chronic rat feeding study,
                    survival was not adversely affected by treatment.  However, body weight
                    gain was reduced and there was destruction and loss of red blood cells.
                         Chlorpropham has been evaluated for carcinogenic activity in both
                    the rat and mouse. No treatment-related cancer effects were observed in the
                    study  using mice, and the only treatment-related effects in the rat occurred
                    at a dose considered excessive by the Agency.  The Agency has classified
                    Chlorpropham in Group E (evidence of non-carcinogeniqity for humans)
                    under the Agency's cancer classification guidelines.
                         A developmental study in the rat produced one treatment related fetal
                    effect  - an increased incidence of rudimentary 14th rib.  A developmental
                    study with rabbits resulted in increased embryo resorptions and post-
                   implantation loss. A reproductive rat study affected growth and

-------
  histopathological changes in the .spleen,-.bone marrow, liver, and kidney.
  Chlorpropham tested positive in two out of four mutagenicity studies.

  Dietary Exposure

       People may be exposed to residues 'of chlorpropham through the diet.
  Currently, raw agricultural commodity tolerances for chlorpropham on
  post-harvest potatoes and soybeans are listed under 40 CFR ง 180.181.
  Also, interim tolerances for multiple crops are listed under 40 CFR
  ง 180.319.  The Agency.has reassessed the tolerance on post-harvest
  potatoes and determined that the tolerance value should be lowered from 50
  ppmtoSOppm.
       The tolerance for soybeans and many of the interim tolerances will be
  proposed for revocation because their use sites are no longer supported by
  any registrant of chlorpropham.  It should be noted that revoking these
  tolerances may impact the importation into the United States of
  corresponding food items bearing chlorpropham residues. Any interested
  party who wishes to maintain a chlorpropham residue tolerance for
  importation purposes in the absence of a registered use should contact the
  Agency. In general, the Agency requires the same product chemistry and
  toxicology  data to support an import tolerance as are required to support
  FIFRA registrations. The Agency also requires residue chemistry data
  representative of growing conditions in the exporting countries
      EPA has assessed the dietary risk posed by chlorpropham, When risk
  was estimated based on tolerance level residues of 30 ppm on potatoes, the
  Anticipated Residue Concentration (ARC) for the overalLU.S. population
  represents 42% of the Reference Dose (RfD)  The RfD is the amount  .
  believed not to cause adverse effects^ consumed daily over a 70-year
  lifetime.  Any exposure level less than 100% of the RfD is considered to be
  an acceptable dietary risk. The most highly exposed subgroup, children 1
 to 6 years of age, has an ARC which represents 85% of the RfD. Therefore,
 it appears that chronic dietary risk is minimal.

 Occupational and Residential Exposure
      Chlorpropham is not currently registered for residential use.
 Consequently, Margins of Exposure (MOEs), a ratio of the estimated
 exposure level to the no observed effect level (NOEL) of 5QO mg/kg/day
.from a 21-day dermal study, were only calculated for occupational handlers
 of chlorpropham in high exposure potential scenarios.

'Human Risk Assessment
      Acute dietary exposure is anticipated to be significantly lower than
 2.5 mg/kg/day, which is, the exposure that would trigger a  concern based on
 effects from the developmental rabbit study. Chronic dietary risk was

-------
  assessed and exposure to the general population and all subgroups was less
  than the RfD.
       Although chlorpropham is classified •;  * group E chemical (evidence
  of non-carcinogenicity for humans) according to the Agency's cancer \
•  classification guidelines, one of its metabolites, 3-chloroaniline, is
  structurally similar to a known carcinogen, 4-chloroaniline. There are no
  cancer data available on 3-chloroaniline. However, the Agency believes it
  is appropriate to use the cancer potency (Qj*) from 4-chloroaniline to gauge
  any potential risk from 3-chloroaniline. Based on the structure of the
  compounds, the. Agency believes that 3-chloroaniline is probably, at most,
  equally as potent and not likely to be more potent than 4-chloroaniline.
       Two risk scenarios were used in the dietary cancer risk assessment.
  One scenario would be more typical of the nationwide risk to chlorpropham
  as this chemical is currently used.  This scenario assumes that the average
  public is exposed to 3-chloroaniline solely through residues on stored
  potatoes.
       The second scenario, termed the  "local milkshed" scenario, describes
 what could be a higher exposure in rural communities where cattle are fed
 potato peelings.  This scenario assumes that residues of 3-chloroaniline
 would be present in beef liver based on a cattle diet of 75% treated potato
 waste and in milk at half the limu of detection. It further assumes that these
 food commodities are distributed locally.
       The cancer risk assessment from  the typical nationwide,scenario
 resulted in a risk estimate of 3 x ICT6. The resulting risk estimate from the
 local milkshed assessment was  4 x 10"6. Both of these risk estimates exceed
 the 1 x W6 estimate of individual excess lifetime cancer risk generally
 considered to be negligible. However,  for the reasons noted below, the
 Agency believes these numbers likely represent an  overestimation of risk.
 (If new chlorpropham food uses are registered in the future which would
 increase the dietary exposure to 3-chloroaniline, the Agency may require
 additional data regarding the toxicity of 3-chloroaniline.)
 •    Based on a study by Amdur et al (1991), 3-chloroaniline would not be
      expected to be more potent than 4-chloroaniline.
 •    Rat metabolism studies detected 3-chloroaniline but no 4-
      chloroaniline.
 •    An oncogenicity study of chlorpropham in rats did produce an
      increase in testicular Leydig cell adenomas. These benign tumors
      were only observed at one excessive dose level (higher than tl-
      maximum tolerated dose).  Yet none of the tumor types which have
      been observed in 4-chloroaniline  data were present in the
      chlorpropham studies (i.e, the 3-chloroaniline that was present in the
      test was not observed having a similar mode-of-actiori effect).

       The cancer dietary risk from spinach is likely to be small compared to
, potatoes because of its lower consumption: and lower residues. .However, if
  the spinach use is maintained, plan^metabolism and possibly field residue
  studies analyzing for 3-chloroaniline may be required
       MOEs :were calculated for occupational handlers in high exposure
  potential scenarios,  the resulting MOEs are all greater than 100, indicating
  only minimal concerns.

       All data requirements.for the indoor use of chlorpropham have been
  fulfilled. It was not necessary to perform a risk assessment for ecological
  effects for me indoor use of chlorpropham,
       The three outdoor uses of chlorpropham (spinach,. Easter lilies, and
  ginkgo trees) were registered as Special Local Needs under FIFRA Section
  24(c) and are not being supported by ihe primary registrants of technical
  chlorpropham. In order to maintain these registrations, environmental fate
  and ecological effects data will have to be submitted.

      EPA is requiring additional generic residue data to confirm its
 regulatory assessments and conclusions for the use of chlorpropham on
 potatoes.  The Agency is requiring additional studies in, the areas of residue
 chemistry, ecological effects, and environmental fate to maintain the
 outdoor uses of chlorpropham
      The Agency also is requiring product-specific data including product
 chemistry and acute toxicity studies, revised  Confidential Statements of
 Formula (CSFs), and revised labeling for reregi strati on.

      AH chlorpropham end-use products must comply with EPA's current
 pesticide product .labeling requirements. For a comprehensive list of
 labeling requirements, please see the chlorpropham RED document.
      Minimum personal protective equipment (PPE) for all occupational
 handlers is chemical resistant gloves. A restricted-entry interval of 12 hours
 has been established for the two uses (Easter lilies and spinach) which are
within the scope of the Worker Protection Standard (WPS).  PPE required
for persons who must enter areas that remain  under a restricted-entry
interval includes coveralls, chemical-resistant gloves, shoes, and socks:
The Agency is requiring a respirator as PPE during application and
ventilation of stored potatoes when chlorpropham is applied as an aerosol
or through forced-air distribution^
     The Agency is also establishing the following entry restriction for
uses of chlorpropham on stored  potatoes when it has been applied as an
aerosol or through forced-air distribution:
     "Do not enter or allow any person, other than a person equipped with
     the appropriate handler personal protective equipment .including a

       respirator, to enter the treated area until the area has been ventilated
       for either a total of two (2) hours with fans or other mechanical
       ventilation or four (4) hours with windows, vents, or other passive
       ventilation or until such time as ,10 complete air exchanges have
       occurred. The ventilation time may be interrupted, i.e., the time may
       be accumulated at sporadic intervals, such as 15 minutes of
       ventilation followed by a period with no ventilation, until the total
       required ventilation time has accumulated."
       Chlorpropham products which are labeled for application to potatoes
 on a conveyor belt must contain the following statement:
       "Following application, workers (e.g. baggers) must wear chemical-
       resistant gloves while potatoes are wet."

       The Agency has determined that the nationwide use of chlorpropham
 on stored potatoes to inhibit sprouting as currently registered will not cause
 unreasonable risk to humans or the environment and this use is eligible for
 reregistration. These products will be reregistered once the required
 confirmatory generic data, product specific data, CSFs, and revised labeling
 are received and accepted by EPA.
      However, there are four registrations of chlorpropham on potatoes
 first registered under Section 24(c) of FIFRA in the states of North Dakota,
 Oregon, and Washington which have application rates not supported by
 field residue data.  These products are eligible for reregistration, provided
 registrants of these products reduce their label application rates or submit
 additional field residue data to the Agency which support these higher rates.
      In addition, there are currently seven chlorpropham registrations first
 registered under Section 24(c) of FIFRA restricted to particular states or
 counties for use on spinach, Easter lilies, and ginkgo trees.  There are
 insufficient data to make a reregistration eligibility decision on these
 outdoor uses of chlorpropham. The Agency is requiring additional studies
 in the areas of residue chemistry, ecological effects, and environmental fate
 to maintain these uses.  There are sufficient data available to support the
 existing interim tolerance on spinach while new data are generated.

         I am pleased to announce that the Environmental Protection Agency has completed its
  reregistration eligibility review and decisions on the pesticide chemical case 0271 which
  includes the active ingredient chlorprophairi.  The enclosed Reregistration Eligibility Denisinn
  (RED) contains the Agency's evaluation of the data base of these chemicals, its conclusions
  of the potential human health and environmental risks of the current product uses, and its
  decisions and conditions under which these uses and products will ,be eligible for
  reregistration.  The RED includes the data and labeling requirements for products for
  reregistration.  It also includes requirements for additional data (generic) on the active
  ingredients to confirm the risk assessments.

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

        Please note that this RED was finalized and signed prior to August 3, 1996  On that
  date, the Food  Quality Protection Act of 1996 (FQPA) became effective, amending portions
  of both the pesticide law (FIFRA) and the food and  drug law (FFDCA). This RED does not
  address any issues raised by FQPA, and any tolerance-related statements in the RED did not
  take into account any changes in tolerance assessment procedures required under FQPA,  To
  the extent that this RED indicates that a change.in any tolerance is necessary, that
  determination will be reassessed by, the Agency under the standards set forth'in FQPA before
  a proposed tolerance is issued.  To the extent that the RED does not indicate,that a change-in
,  a tolerance is necessary, that tolerance too will be reassessed in the future pursuant to the

        Chlorpropham was registered in the. United States in 1962 as a pre-emergence and
 post-emergence herbicide and as a plant growth regulator. It was originally .registered for use
 on a variety of terrestrial food crops, nonfood crops, and ornamentals to control broadleaf
 weeds and grasses, and sprouting in stored potatoes.  The Agency published an evaluation of
 existing data and identified data gaps in the December, 1987 Guidance for the Reregistration
 of Pesticide Products Containing Chlorpropham as the Active Ingredient (NTIS #PB88-
 169917). The 1987 guidance document (referred to as "Registration Standard") required
 additional data in the areas of product chemistry, residue chemistry, toxicology, ecological
 effects, and environmental fate.  By1990, the primary registrants had dropped all nationwide
 uses of chlorpropham except for sprout control on post-harvest stored potatoes. However, an
 additional 1.1 registrations for use within a particular county or state [registered under FIFRA
 Section 24(c)] remain today for use on spinach, Easter lilies, and ginkgo trees.-

     •. A Data Call-in (D'CI) was issued,in 1994 for chlorpropham requiring an analytical
 method to detect a metabolite of chlorpropham, 4-hydroxychlorpropham-O-sulfonic acid, and
 a residue study to test for that metabolite in meat and milk. The Agency is considering these
 data confirmatory to the decisions in this reregistration document.                       "

       The Agency has  determined that the nationwide uses of chlorpropham on stored
 potatoes to inhibit sprouting as currently registered will not cause unreasonable risk to
 humans or the environment and this use is eligible for reregistration.  However, there are four
 registrations first registered under Section 24(c) of FIFRA in the states of North Dakota,
 Oregon, and Washington that have an application rate that is not supported by field residue
 data. These products are eligible for reregistration, provided registrants of these products
 reduce their label application rates or submit additional field residue data to the Agency that
 support these higher rates! '                                                       -

       In addition, there are. currently seven chlorpropham registrations first registered under
 Section 24(c) of FIFRA  restricted to particular.states or counties for use on spinach, Easter
lilies, and ginkgo trees.  There are insufficient data to make a reregistration eligibility decision
on these outdoor uses of .chlorpropham.  The Agency is requiring additional studies in the
areas of residue chemistry, ecological effects, and environmental fate to maintain these uses.

-------
 There are sufficient data available to support the existing interim tolerance on spinach while
 new data are generated,                   '         '

 HEALTH EFFECTS

       The chlorpropham Reference Dose (RfD) of 0.05 mg/kg bwt/day established by the
 Agency for a chronic dietary exposure risk assessment was based on the no effect level of 5
 mg/kg bwt/day from a chronic feeding study with dogs.  Dietary exposure to chlorpropham
 can be through either of it's two food uses - spinach or potatoes.  The contribution to chronic
 dietary risk from spinach is negligible. The  estimate for chronic dietary risk is driven by the
 primary use of chlorpropham on stored potatoes.

       The current chlorpropham tolerance on stored potatoes is 50 ppm. The existing field
 data support a tolerance of 30 ppm. When risk was estimated based on tolerance level
 residues of 50 ppm, the RfD was exceeded for children 1-6 years of age. However, when
 risk was estimated assuming that 60% of all  potatoes have chlorpropham residues at the
 revised tolerance value of 30 ppm , RfDs were not exceeded for any subgroup of the
 population. Estimated risk would be substantially lower if field residues were used rather
 than tolerance.values.

       Although chlorpropham is classified as  a group E chemical (evidence ofnon-
 carcinog'enicity for humans) according to the Agency's cancer classification guidelines, one of
 its metabolites, 3-chloroanjline, is structurally similar to a known carcinogen, 4-chloroaniline.
 There are no cancer data available on 3-chloroaniline.  However, the Agency believes it is
 appropriate to use the cancer potency (Q,'*) from 4-chloroaniline to gauge any potential risk
 from 3-chloroaniline.  Based on the structure of the compounds, the Agency believes that 3-
 chloroaniline is probably, at most, equally as potent and not likely to be more potent than 4-
 chloroaniline.                      .

       T>                    '  '                      *
       Two risk scenarios were used in the dietary cancer risk assessment.  One scenario
would be more typical of the nationwide risk to chlorpropham as this chemical is currently
used. This scenario assumes that the average public is  exposed to 3-chloroaniline solely
through residues on stored potatoes.

       The second scenario, termed the "local milkshed" scenario, describes what could be a
higher exposure in rural communities where  cattle are fed potato peelings. This scenario
assumes that residues of 3-chloroaniline would be present in beef liver based on a cattle diet
of 75% treated potato waste and in .mflk-at half the limit of detection.  It further assumes that
these food commodities are  distributed locally.

      The cancer risk assessment from the typical nationwide scenario resulted in a.risk
estimate of 3 x W6. The resulting risk estimate from the local milkshed assessment was 4 x
W6. Both of these risk estimates exceed the  1 x W6 estimate of individual excess lifetime
                                         VI

-------
  cancer risk generally.considered to be. negligible. However, for the reasons noted below  the
  Agency believes these numbers may likely represent an overestimation of risk.  (If new '
  chlorpropham food uses are registered in the future which would increase the dietary
  exposure to 3-chloroaniline, the Agency may require additional data regarding the toxicitv of
  3-chloroaniline.)   '

  •     A study by Amdur etal (1991) showed that the substitution of aromatic amines such
        as aniline with an electron donating adduct such as chlorine in either the ortho (1) or
        para (4) position (e.g; 4-chloroaniline) relative to the amino group resulted in greater
        potency than observed/or the parent compound, whereas substitution in the meta (3)
        position (e.g. 3-chlofoaniline) was not likely to cause increased potency: Therefore 3-
        chloroaniline would not be expected to be more potent than 4-chloroaniline.

 •     Rat metabolism studies detected 3-chloroaniline but no 4-chlorqaniline.

 •     An oncogenicity study of chlorpropham in rats did produce an increase in testicular  ~
        Leydig cell adenomas.  These benign tumors were only observed at one excessive dose
        level (higher than he maximum tolerated dose). Yet none of the tumor types which
     .'   haye been observed in 4-chloroaniline data were present in the chlorpropham studies
        (i.e, the 3-chloroaniline that was present in the test was not observed having a similar
        moderof-action effect).;

        The cancer dietary risk from spinach is likely to be small compared to potatoes
 because of its lower consumption and lower residues.  However, if the spinach use is
 maintained, plant metabolism and possibly field residue studies analyzing for 3-chloroaniline
 may be required.           ,         ^          .--"..••

 OCCUPATIONALAND RESIDENTIAL EXPOSURE
                     is n0t currently registered for residential use. Consequently, margins of
Exposure (MOEs), a ratio of the estimated exposure level to the no observed effect level
(NOEL) of 500 mg/kg/day from a 21-day dermal study, were only calculated for
chlorpropham occupational handlers in high exposure potential scenarios.  The resulting
MOEs indicated only minimal concerns for occupational exposure to chlorpropham.

       Minimum personal protective equipment for all occupational-handlers is chemical
resistant gloves.  A restricted-entry interval of 12 hours has been established for the two uses
(Easter lilies and spinach) which are within the scope of the Worker Protection Standard
(WPS). Personal protective equipment required for. persons who must enter areas that remain
under a restricted-entry interval includes coveralls,  chemical-resistant gloves shoes and
socks.  The Agency is requiring a respirator as PPE during application and ventilation of
stored potatoes when chlorpropham, is applied as an aerosol or through forced-air distribution
                                         vn

-------
        The Agency is also establishing the following entry restriction for uses of
  chlorpropham on stored potatoes when it has been applied as an aerosol or through forced-air
  distribution:                                                            .

        appro;:, tate handler personal protective equipment including a respirator,  to
        enter the treated area until the area has been ventilated for either a total of two
        (2) hours with fans or other mechanical ventilation or four (4) hours with
        windows, vents, or other passive ventilation or until such time as 10 complete
        air exchanges have occurred.  The ventilation time may be interrupted, i.e., the
        time may be accumulated at sporadic intervals, such as  15 minutes of'   '
        ventilation followed by a period with no ventilation, until the total required
        ventilation time has accumulated.

        Chlorpropham products which are labeled for application to potatoes on a conveyor
 belt must contain the following statement:

        Following application, workers (e.g.- baggers) must wear chemical-resistant gloves
        while potatoes are wet.

 ENVDRONMENTAL FATE AND ECOLOGICAL EFFECTS

        AH data requirements for the indoor use of chlorpropham have been fulfilled. It was
 not necessary to perform a risk assessment for ecological effects for the indoor use of
 chlorpropham.

    _   The three outdoor uses of chlorpropham (spinach, Easter lilies, and ginkgo trees) were
 registered as Special Local Needs under FIFRA Section 24(c) and are not being supported by
 the primary registrants of technical chlorpropham. In order to maintain these registrations
 environmental fate and ecological effects data will have to*be submitted.

 TOLERANCE REASSESSMENT

       Currently, there are raw agricultural tolerances for chlorpropham on post-harvest
 potatoes and soybeans listed under 40 CFR ง 180.181. There are also interim tolerances on
 multiple crops listed under 40  CFR ง180.319.  The Agency has reassessed the tolerance on
 post-harvest potatoes and determined that the tolerance value should be lowered from 50 nom
 to 30 ppm.                                                                     • ^

       The tolerance on soybeans and many of the interim tolerances will be proposed for
revocation because their use sites are no longer supported by any registrant of chlorpropham
It should be noted that revoking these tolerances may impact the importation into the United
States of correspor • ig food items bearing chlorpropham residues.  Any interested party who
                                        via

-------
 wishes to maintain a chlorpropham residue tolerance for importation purposes in the absence
-of a registered use should contact,the Agency. In general,: the Agency requires the same
 product chemistry and toxicology data to support an import tolerance as are required to
 support FIFRA registrations.  The Agency also requires residue chemistry data representative
 of growing conditions in the exporting countries.

 PRODUCT REREGISTRATION                      •   x            ;

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

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

       FIFRA Section 4(g)(2)(A) states that in Phase 5 "the Administrator shall determine
 whether pesticides containing such active ingredient are.eligible for reregistration," before
 calling in data on products and either reregistering products or taking "other appropriate
 regulatory action." Thus, reregistration involves a thorough review of the scientific data base
 underlying a pesticide's registration. The purpose of the Agency's review is to reassess the
 potential hazards Arising from the currently registered uses of the pesticide; to determine the
 need for additional data on health and environmental effects; and to determine whether the
 pesticide meets the "no unreasonable adverse effects" criterion of FIFRA

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

        D.     Regulatory History
               Chlorpropham was registered in the United States in 1962 as a pre-emergence
        and post-emergence herbicide and as a plant growth regulator. It was originally
        registered for use on a variety of terrestrial food crops, nonfood crops and
        ornamentals to control broadleaf weeds and grasses, and sprouting in stored potatoes
        The Agency published an evaluation of existing data and identified data gaps in the
        December,  1987 Guidance for the Reregi strati on of Pesticide Products Containing
        Chlorpropham (NTIS #PB88-169917). The 1987 guidance document (referred to as
         Registration Standard") required additional data in the areas of product chemistry
        residue chemistry, toxicology, ecological effects, and environmental fate  By 1990
        the primary registrants had dropped all nationwide uses of Chlorpropham except for'
        sprout control on post-harvest stored potatoes. However, an additional 11 registrations
        for use within a particular county or state (registered under FIFRA 24(c)) remain today
        for use on spinach, Easter lilies, and ginkgo trees. Chlorpropham is used as an
        herbicide to control mouseear chickweed in spinach and in an integrated pest
        management method to decrease Botrytis infection, on Easter lilies. As a plant growth
        regulator, Chlorpropham is used to inhibit sprouting in stored potatoes and control
        iruitinor in Oinlran -H-aaa
fruiting in ginkgo trees.
              A Data Call-in (DCI) was issued in 1994 for Chlorpropham requiring an
       analytical method to detect a metabolite of Chlorpropham, 4-hydroxychlorpropham-O-
       sulfomc acid, and a residue study to test for that metabolite in meat and milk  These
       data are not due to the Agency until October, 1995. The Agency is considering these
       data confirmatory to the decisions in this ^registration document. Should a change in •
       the Agency s regulatory position be warranted by the incoming data, a Federal Register
       Notice would be issued. This Registration Eligibility Decision reflects a
       reassessment of all data which were submitted in response to the Registration
       standard.

       A 21-day dermal study was conducted with male and female
New Zealand wHte rabbits.  Chlorpropham was applied to intact skin at
dose levels of C, 00, 500, or 1000 mg/kg/day for 6 hours/day, 7
days/week.  On three occasions some animals were exposed for 24
hours.  All dose levels produced dermal irritation consisting of
erythema, edema, cracking, and scaling. Histopathological findings in
the skin included minimal acanthosis, hyperkeratosis, and focal
inflammatory cells. The only systemic effect was a dose-related
increase in reticulocytes in blood of both sexes that was significant at
the highest dose of 1000 mg/kg/day.  Hematology revealed no other
indications of anemia. An increase in spleen weight (relative to brain
weight) at the high dose was possibly related to the increase in
reticulocytes. The effect on reticulocyte count was consistent with
hematological findings of erythrocyte destruction/loss in longer-term
studies. The NOEL for dermal effects was less than the lowest dose of
100 mg/kg/day,,and the LOEL was 100 mg/kg/day. The NOEL for
systemic toxicity'was 500 mg/kg/day, and the LOEL was 1000
mg/kg/day based on the increase in reticulocyte count (MRID
41899901).

       A 90-day feeding study with rats and a 28-day dog study were
supplementary.  The subchronic feeding study requirements are satisfied
by the two-year rat and 60-week dog studies.

c.     Chronic Toxicity

       A 60-week study was conducted with male and female beagle
dogs. Chlorpropham was orally adminir, :red in the diet at dose levels
of 0, 5, 50, 350, or 500 mg/kg/day. The diets containing 350 or 500
mg/kg/day were unpalatable, causing marked reductions in food
consumption and body weight gain during the initial weeks of the study.

-------
  Food consumption returned to normal by the dogs adapting to the diet;
  or manipulation of the test material concentration; however, body
  weight gain of the 350 and 500 mg/kg/day dose groups remained
  depressed throughout the study. Anemia was evident at the two highest
  dose levels. Erythrocyte count, hemoglobin,,and hematocrit were
 . reduced, and mean corpuscular volume (MCV) was increased.  Changes
  in thyroid function and morphology were prominent effects of
  treatment. Doses of 50 mg/kg/day and above resulted in increased
  thyroid weight with associated histopathological changes. The thyroid
  showed moderate to marked changes characterized by irregular shaped
  follicles lined by medium to high cuboidal epithelium; follicles
  contained clear to pale stained "colloid. Serum T3 and T4 levels were
  reduced at 350 and 500 mg/kg/day. Thyroid, response to TSH was
  depressed at these dose levels. Cholesterol was increased at 350 and
  500 mg/kg/day.  The NOEL was 5 mg/kg/day. The LOEL was 50
  mg/kg/day based on evidence of thyroid effects at this dose level
  (MRID 42189501),

        In a two-year chronic toxicity/carcinogenicity study, male and
 female Sprague-Dawley rats were fed4iets at dose levels of 0, 30, 100
 500, or  1000 mg/kg/day of chlorprbpham. Survival was not adversely'
 affected by treatment.  In fact, survival showed a dose-related increase
 with increasing dose.  Body weight gain was  reduced at the two highest
. dose levels. Indications of erythrocyte destruction or loss were evident
 at 100 mg/kg/day and higher.  Erythrocyte count, hematocrit, and
 hemoglobin were decreased. Hematopoiesis  in bone marrow and
 splenic hemosiderosis were increased.  Additional compensatory
 changes or consequences of the anemia were  observed at 500
 mg/kg/day arid above.  The findings jncluded increased reticulocyte
 count; inereased,hematopoiesis.(liver, spleen, bone marrow), increased
 spleen weight, pignient accumulation in liver  and kidney tubules and
 presence of bilirubin in urine;  At the two highest doses, blood .was dark
 with a brown tint suggestive of methemoglobinemia (but unconfirmed)
 Morphological study of erythrocytes revealed crenated and
 polychromatic cells at the two highest dose levels.  Crenated cells
 (associated with erythrocyte destruction) were rriost marked early in
 treatment whereas polychromatic cells (associated .with compensation)
 were most marked later in the study.  Cholesterol levels were increased -
 at 500 and  1000 mg/kg/day.  The NOEL was 30 mg/kg/day, and the
LOEL was 100 mg/kg/day based on the hematological effects (MRID
42754701).                     .                      •./..'

-------
 d.     Carcinogenicity

       In a two-year chronic toxicity/carcinogenicity study, male and
 female Sprague-Dawley rats were fed diets at dose levels of 0, 30, 100,
 500, or 1000 mg/kg/day of chlorpropham.  Survival  showed a dose-
 related increase with increasing dose. Body weight gain was  reduced at
 the two highest dose levels. Indications of hemolytic anemia  were
 evident at 100 mg/kg/day and higher. The only neoplastic lesion related
 to treatment was benign testicular Leydig cell tumor. The incidence
 showed a dose-related trend and was significantly increased (pair-wise
 comparison) at the highest dose.  The incidence of focal hyperplasia of
 Leydig cells showed a similar dose-response relationship (MRID
 42754701).

       An 18-month c'arcinogenicity study was conducted with male
 and female CD-I mice. Chlorpropham was administered in the diet at
 dose levels of 0, 100, 500, or 1000 mg/kg/day of chlorpropham.
 Survival of males was reduced at the highest dose of 1000 mg/kg/day.
 Doses of 500 and 1000 mg/kg/day were associated with hematological
 and hematopoietic organ changes indicative of erythrocyte destruction
 or loss. Hematopoiesis (spleen, liver, bone marrow), hemosiderosis
 (spleen), and bone marrow cellularity were increased in severity and/or
 incidence at 500 and 1000 mg/kg/day. Dark eyes and a bluish tint of
 the skin in these animals were suggestive of methemoglobinemia (but
 unconfirmed). Related compensatory findings observed at the high
 dose only included elevated reticulocyte count, MCH, and MCHC and
 increased spleen and liver weights. No neoplastic lesions were related   •
 to treatment (MRID 42530301).

       On July 20, 1994, the Agency classified chlorpropham in Group
E (evidence of non-carcinogenicity for humans). The classification was
 supported by the following evidence: 1) a lack of carcinogenic potential
 demonstrated in mice and 2) the increase in benign Leydig cell tumors
in rats occurred only at ah excessive dose.

e.     Developmental Toxicity

       A developmental toxicity study was conducted with pregnant
Sprague Dawley rats administered doses of 0,  100, 350, or 1000
mg/kg/day of chlorpropham by gavage on days 6 through 19 of
gestation. Dams were sacrificed on day 20  of gestation. Doses of 350
and 1000 mg/kg/day were maternally toxic. Dams in these dose groups
experienced clinical signs, reduced body weight gain, and enlarged

-------
  spleens.  Clinical signs included salivation, urogenital staining, arid red
  staining around the mouth, nares, and eyes, A single fetal effect was'
  associated with the high dose group. These fetuses had an increased
  incidence of rudimentary 14th rib. No other litter or fetal effects were
  related to treatment. The NOEL for maternal toxicity was 100
  mg/kg/day, and the LOEL was 350 mg/kg/day:based on .clinical signs
  and reduced weight gain.  The developmental  toxicity NOEL was 350
  mg/kg/day, and the LOEL was 1000 mg/kg/day based on the increased
  incidence of 14th rib (MRID 00093 921).   •'.,.-'"     .:""-''".

        A developmental toxicity study was conducted with New
 Zealand white rabbits given doses of 0, 125, 250, or 500 mg/kg/day of,
  chlorpropham by gavage on days 6 through 18 of gestation.  Does were
  sacrificed on day 29 of gestation. The high dose of 500 mg/kg/day was
 maternally toxic producing clinical signs including cold ears, anorexia,
 reduced fecal output, and blood stained urine!  The high dose affected'
 litter size by increasing embryo resorptions and post-implantation loss.
, The NOEL was 250 mg/kg/day and the LOEL was 500  mg/kg/day for
 both maternal and developmental toxicity (MRID 00129940).

 f.     Reproductive Toxicity

       A two-generation reproduction study was conducted with
 Spragu.e-Dawley-derived CD rats. Chlorpropham was administered in
 the diet at concentrations of 0,  1000, 3000, or 10,000 ppm. These levels
 were equivalent to 50,  150, and 500 mg/kg/day, respectively. Body
 weight gain by adults (F0 and Fi) and lactating  pups (Fi  and F2) of both
 generations was depressed at 500 mg/kg/day. Growth was also
 depressed at 150 mg/kg/day in  the Regeneration post-weaning.
 Changes in spleen, bone marrow, and other organs were observed at
 15.0 mg/kg/day and above in weanlings .or adults of the Fl generation.
 Spleens of weanlings had a dark red appearance grossly. In adults,
 spleen weight was increased and brown pigment granules were
 observed in reticulbendothelial  cells of the spleen. Similar pigmentation
 was seen in liver Kupffer cells and kidney convoluted tubule
 epithelium.  Bone marrow hyper cellularity was also observed in Fr
 adults. These  effects, were consistent with findings of other studies
 showing hematotoxicity (i.e., erythrocyte loss or destruction). :
 Reproductive indices were unaffected by treatment. A decrease in
 ovary weight was observed in Fj (all doses) and F2 (2 highest  doses)
 weanlings, but was unaccompanied by gross or microscopic changes.
 The ovary was normal in F1 adults.  The NOEL for systemic toxicity
 was 50 mg/kg/day,-and the LOEL was 150 mg/kg/day based on effects

-------
 on growth and histopathologicai changes in the spleen, bone marrow,
 liver and kidney,  The NOEL for reproductive toxicity was the highest
 dose tested, 500 mg/kg/day (MRID 00129545).

 g.     Mutagenicity

       A gene mutation assay in mammalian cells was conducted using.
 the L5178Y(TK+/-) mouse lymphoma cell line. Complete toxicity
 occurred at ohlorpropham concentrations of 1000 jig/ml and greater
 with or without metabolic activation (PCB-induced rat liver S9).
 Concentrations of 13 to 75 ng/ml were tested without metabolic
 activation; growth was 41 to 100% of control cultures.  Concentrations
 of 13 to 100 ug/ml were tested with metabolic activation; growth was 8
 to 52% of control cultures. Chlorpropham had no effect on mutation
 frequency with or without metabolic activation (MRID 00129938).

       Chlorpropham was tested for cytogenetic effects in vitro using
 Chinese hamster ovary cells.  Metaphase cells were collected 10 and 20
 hours after treatment.  Concentrations of 149 ug/ml and higher were
 cytotoxic. Concentrations tested ranged from  10 to 160 ng/ml with or
 without metabolic activation (PCB-induced rat liver S9).  Chlorpropham
 was presumptively positive with metabolic activation at moderately
 toxic doses (120, 140 ng/ml).  Chlorpropham was negative without
 metabolic activation, but this portion of the assay was incompletely
 performed (i.e., single trial; no 10-hr evaluation) (MRID 41846701).

       Chlorpropham was tested in an in. vitro transformation assay
 using Syrian hamster embryo cells. Six concentrations of Chlorpropham
 (5-30 ug/ml) were tested in a continuous (7-day) exposure regimen.
 Five concentrations (85-115 ng/ml) we're tested for 24 hours, which
 included a 7-day refeeding regimen. Chlorpropham was positive for
 producing morphological transformations. Both the continuous
 exposure and the 24-hour exposure resulted in a significant increase in
 the frequency of transformations (MRID 41845501).

       Two potential metabolites of Chlorpropham were evaluated in the
 Salmonella tvphimurium mutation assay using tester strains TA 98, TA
 100, TA 1535, TA 1537, and TA 1538. The compounds tested were
isopropyl 5-chloro-2-hydroxycarbanilate and isopropyl 3-chloro-4-
hydroxycarbanilate.  Both tested negative with and without metabolic
activation  (PCB-induced rat liver S9) in all strains (MRID 00126733
and 00126734),
                    . 10

  h.
Metabolism
        The pharmacokinetics of chlorpropham was evaluated in male
  and female Sprague-Dawley,rats following a single intravenous dose
  (0.5 mg/kg), single orallow dose (5 mg/kg), single oral highdose (200
  mg/kg), or repeated orallow doses (5 mg/kg/day for 15 days). With all
  dosing regimens, chlorpropham was rapidly absorbed and essentially
  completely metabolized prior'to excretion in urine with small amounts
  in feces. Within 24 hours 82-92% of .the radiolabel was recovered in
  the urine and 3-5 % in the feces. Peak excretion at the low dose
  occurred at 4^12 hours (49-62% of the dose) and at the high dose   '-
  between 8-24 hours (59-64% of the dose). Less than 0.3% of doses
  were recovered at C14-CO2 over a three day period.  The approximate
  half-life of ehlorpropham was 8 hours at the low dose and 9 hours at the
  high dose in males and females. Three major metabolic routes were
  proposed: (1) hydroxylation at the 4'-position and conjugation, (2)
  oxidation  of the isopropyl side chain to form isopropanol and '
  isopropinate moieties; (3) decarbamilatibn to form 3.chloroaniline
'  followed by N-acetylation, 4'-hydroxylation, and conjugation fMRID
  42006901),   .   "

  u      Other Toxic Endpoints: Neurotoxicity

        Chlorpropham was tested for acute delayed neurotoxicity. Adult
 domestic hens were given 0, 1250, 2500, or 5000 mg/kg as a single oral
 dose.  The LD^.was shown to be greater than 5000 mg/kg in a
 preliminary study.  TOCP was the positive control, Chlorpropham did
 not show any potential for producing delayed neurotoxicity. No
 mortality, clinical signs, or histopath^logy, was associated with any dose,
 level.  The study was a limit test using the maximum dose (5000 mg/kg)
 required in testing for acute delayed neurotoxicity (MRID 00093915).

 j.     World Health Organization Review

       Chlorpropham was evaluated at the Joint Food and Agriculture
 Organization/World Health Organization Meeting on Pesticide Residues
 (JMPR) in  1963 and 1965, but no Acceptable Daily Intake (ADI) was
 allocated. The toxicology and residue chemistry of chlorpropham is
 scheduled to be evaluated by the JMPR in  September of 1995. An ADI
 may be. set'as a consequence of this evaluation.                    ~
                      11

-------
       k.    Reference Dose (RfD) for Chronic Oral Exposure

             The Agency established 0.05 mg/kg/day as the RfD for
       chlorpropham, based on the results of a one-year feeding study in dogs
     '  (MRID 42189501).  The NOEL from the dog study was 5 mg/kg/day
       and an uncertainty factor of 100 was used to derive the RfD for
       chlorpropham.

2.     Exposure Assessment

       a.     Dietary Exposure

             The summaries of residue chemistry data listed below are based
       on the post-harvest application use on stored potatoes. Additional data
       will be required if the spinach use is maintained.

       Plant Metabolism: The qualitative nature of the residue in stored potato
       treated post-harvest is adequately understood. The parent chlorpropham
       was found to be the major residue, representing 96% of the total
       radioactive residues (TRR), in potato stored for 52 weeks following
       treatment with [14C]chlorpropham at 2.4x the maximum registered rate.
       Although this indicates that little metabolism of chlorpropham occurs in
       stored potato, some metabolites of chlorpropham were detected (each at
      <1,3% of TRR), indicating that chlorpropham may metabolize through
      hydroxylation of the aniline ring or the isopropyl side chain, with
      subsequent conjugation with carbohydrates or ammo acids.
      Decarbanilation also occurs, forming 3-chloroaniline. The regulated
      metabolite (l-hydrpxy-2-propyl-3-chlorocarbanilate) was not detected,
      but an oligosaccharide conjugate of Jhis metabolite was detected at
      0.03% TRR. The  3-chloroaniline metabolite and its glucose conjugate
      were also identified at a combined level of 0.58% TRR.

            The Agency has determined that the metabolite l-hydroxy-2-
      propyl-3-chlorocarbanilate does not need to be included in the tolerance
      expression for potato. The Agency also judged that the tolerance
      expression in potatoes should not include the 3-chloroaniline
      compound, but that a risk assessment for this metabolite should be
      included in the RED document. This risk assessment should be
      performed using anticipated residues of 3-chloroaniline along with the
      Q* associated with 4-chloroaniline. The Agency recognized that this
      latter assumption may overestimate the risk associated with 3-
      chloroaniline, but believed that no reliable information exists at this
      time to refute or provide a more reasonable assumption.
                           12

-------
        In order to maintain the spinach use, a plant metabolism study is
  required.

  Animal Metabolism: The qualitative nature of the residue in poultry is
  adequately understood for the purposes of the limited use of
  chlorpropham.  The qualitative nature of the residue in ruminants is
  adequately understood.

        The metabolism of chlorpropham in ruminants and poultry is
  proposed to proceed through oxidation to 4-hydroxychiorpropham or
  degradation to 3-chloroaniline. The hydroxychlorpropham is then
  further metabolized to 4-hydroxychlorpropham-O-sulfonic acid or 4-
  hydroxychl6rpropham-O-glucuronide and the aniline is further
^metabolized to 3-chloro-4-hydroxyaniline-O-sulfonic acid. The 3-
  chloroaniline metabolite wasnot detected in fat, kidney, or milk, but '
 was identified in beef liver at 11% T&R.

       The Agency,has determined that the  residues to be regulated in
 animal commodities are chlorpropham and the.metabolite 4-
 hydroxychlbrpropham-O-sulfonic acid. The Agency has judged that,
 although 3-chloroaniline will not be included in the tolerance
 expression, the dietary risk assessment would include the 3-           :
 chloroaniline metabolite.

 Residue Analytical Methods-Plants and Animals: The PMtiririg
 Analytical Manual (PAM) Vol. H lists several methods as available for -•.
 the enforcement of chlorpropham tolerances in plant commodities and
 milk. The PAM,Vol. I method for chlorinated pesticides is listed as
 Method I and an infrared (IR) method is listed as Method II.  The limit
 of detection for Method II is 1 ppm. Methods A,, B,;and D are
 spectrophotometric methods involving conversion of chlorpropham to
 3-chlbroahiline.  PAM notes, that propham, monuron, diuron, linuron,
 and any other compound forming a volatile aniline on hydrolysis will
 also be determined in these procedures.  Method C is  a gas
 chromatographic method with electron capture detection and involves
 conversion of chlorpropham to bromochloroaniline. Method E is a thin
 layer chromatography (TLG). method and Method F is similar to Method


      Data collection and enforcement  methodology should include
hydrolysis steps in order to detect free and conjugated side-chain
modified metabolites, such,as  1 -hydroxy-2-propyl-3-chlorocarbanilate
and 3^chloroaniline.  A gas chromatographic  method with nitrogen-
                      13

-------
  phosphorus detection has been submitted for the determination of
  chlorpropham and 3-chloroaniline in potato commodities.  The limits of
  detection are estimated to range from 0.05 to 0.08 ppm for potato,
  potato pulp, potato peel, and processed wet peel; from 0.05 to 0.38 ppm
  for granules and dried potato peel; and from 0.05 to 0.45 ppm for potato
  chips. The registrant has submitted an acceptable laboratory validation
  of this method on potatoes.  EPA's Beltsville laboratory has performed
  an acceptable tolerance method validation (TMV) and the Agency is
  awaiting minor changes in the method protocol description from the
  registrant. A method for spinach is required.

        An enforcement analytical method capable of adequately
  detecting the residues of concern (chlorpropham and the metabolite 4-
  hydroxychlorpropham-O-sulfonic acid) in animal commodities must be
  developed and validated using radiolabeled samples from the goat
 metabolism study.

        The FDA PESTDATA database of 8/93 (PAM Vol. I, Appendix
 II) indicates that chlorpropham is completely recovered (>80%) using
 FDA multi-residue method protocols D (Section 232.4) and E (Section
 212.1/232.1, nonfatty matrices and Section 211.1/232.1, fatty matrices).

 Storage Stability: All data requirements pertaining to chlorpropham
 storage stability per se have been evaluated and deemed adequate.
 Residues of chlorpropham per se are  stable during frozen storage at -4C
 in potato and wet potato peel for at least 13 months, in potato chips for
 at least 8 months, in potato granules for at least 9 months, and in
 processed dry peels for at least 12 months. Data on spinach will be
 required if the use is supported.          ,

       No storage stability data are available for animal commodities.
 A data requirement for a ruminant feeding study remains outstanding.
 Unless tissue and milk samples m>m the feeding study are analyzed
 within two weeks of sample collection, storage stability data for
 residues of chlorpropham and 4-hydroxychlorpropham-O-sulfonjc acid
 in animal commodities will be required.

Magnitude of the Residue in Plants- All data requirements pertaining to
the magnitude of chlorpropham residue in stored potato have been
evaluated and deemed adequate.

       Data pertaining to 3-chloroaniline residues in potato have also
been submitted. However, the Agency has determined that the tolerance
                      14

-------
  expression will consist of chlorpropham only, and not the 3-
  chloroaniline metabolite. Instead, the magnitude,of the 3-chloroaniline
  residue in potatoes will be incorporated into the risk assessment:
  adequate magnitude of the 3 -chloroaniline residue data for a risk
  assessment have been submitted.

        Adequate magnitude of the residue data are available to support
  the interim tolerance on spinach^ However, if the spinach use is to be
  supported, an FFDCA Sect. 408itolerance would need to be established.
  Therefore, residue data on spinach, including a decline study, are
  needed.                                                '

 Magnitude of the Residue in Processed Food/Feed: All data
 requirements pertaining to the magnitude of chlorpropham residue in
 processed potato commodities have been evaluated and deemed
 adequate.                      :                     -

 Magnitude of the Residue in Meat Milk. Poultry and Rorpg- A  data
 requirement for a ruminant feeding study remains outstanding.  Since
 potato commodities are not significant poultry feed items, a poultry
 feeding study is not required and tolerances for poultry commodities
 will not be necessary.

       The maximum theoretical dietary burden of chlorpropham for
 ruminants is estimated to be 940 ppm (dry  matter basis) based on a diet
 consisting of 75% .processed potato waste consisting of 88.6% dry
 matter.        .          ..."

 Confined/Field Rotational Crops: Rotational crop studies are not
 required to support use of chlorpropham on stored potato. Confined
 rotational crop data will be required to support the spinach use. Field
 rotational crop data may be necessary pending the results of the
 confined rotational crop data.

 b.    Dietary Exposure Assessment Summary

      A dietary exposure assessment is needed for residues of
 chlorpropham and its 3-chloroaniline metabolite as a result of treatment
 of food and feed commodities with chlorpropham.  Therefore, the
 Agency has estimated residues of both chlorpropham per se and the 3-
 chloroaniline metabolite which was detected in certain commodities
 during the plant and animal metabolism studies. These estimates  are
described in more detail below.
                      15

-------
 Exposure Assessment for Chlorpropham per se: The reassessed
 tolerances for chlorpropham in potato and processed potato
 commodities have been used to estimate dietary risk from chlorpropham
 and 3-chloroaniline.  Reassessment of the tolerances associated with
 meat and milk products is not possible at this time since feeding studies
 with cattle ("Magnitude of the Residue in Ruminants") have not yet
 been performed by the registrant. When this information becomes
 available, the current tolerances associated with these commodities will
 be reassessed. Part IV of this document provides a summary of these
 reassessed tolerances as well as the current tolerances for those
 commodities for which adequate information is not available.  This
 information was used by the Agency to estimate dietary risks associated
 with chlorpropham and 3-chloroaniline.

 Exposure Assessment for 3-Chloroaniline: The Agency decided that the
 potential carcinogenic risk due to the 3-chloroaniline metabolite should
 be assessed.  Since no data are available on the cancer potency of the 3-
 chloroaniline metabolite, this risk was calculated using the cancer
 potency factor (i.e., the C^*) available for the 4-chloroaniline isomer.
 The Agency recognized that using the Q,* value for 4-chloroaniline in
 place of an actual Q/ for 3-chloroaniline may likely overestimate the
 risk associated with 3-chloroaniline.

       The Agency developed anticipated residues for use in assessing
 the dietary risk of the 3-chloroaniline metabolite under two scenarios:, a
 "typical" risk scenario which represents an estimate of exposure on a
 national basis and an upper bound-estimate to represent consumers in a
 local milkshed.. In each case, field trial studies and potato processing
 studies were reviewed to provide estimates of 3-chloroaniline
 concemrations following actual post-harvest fumigation of stored
potatoes. To provide exposure estimates for populations residing in a
local milkshed, metabolism study data were used along with certain
assumptions regarding the percent of the potato crop which is treated
and the livestock dietary burden. The major differences in the
assumptions used in these two scenarios are highlighted in table 2.

                    and milk are assumed only in the milkshed scenario because distribution
                    of processed potato waste for livestock feeding purposes will most
                    likely occur on a local basis in the vicinity of the processing plant.

* The registrant did not supply adequate magnitude of the residue data for concentrations of 3-chloroaniline in
peeled potatoes. However, an article appearing in Pesticide Science demonstrates that approximately 70% of the
radioactivity is present in the skin of the tuber (Coxon, DT and A Filmer, 1985, Pesticide Science  16:355-63).
Thus, the ppm values shown here were calculated by assuming that 70% of the residues are present in 5% of the
potato (which represents peel). The calculation also assumes that 60% of the potatoes are treated with
chlorpropham.                                             .
b The registrant did not peel the potatoes prior to frying them and determining 3-chloroaniline concentrations.
The Agency calculated the anticipated residues in fresh fried potatoes by assuming that (i) 70% of the residues
are present in the peel; (ii) the peel represents 5% of the whole tuber weight; (iii) 95% of the fresh fried potatoes
(french fries and potato chips) are peeled prior to processing. The calculation also assumes that 60% of the
potatoes are treated with chlorpropham.
c This value is assumed to equal the value for processed dry peel.              ,
d Although 3-chloroaniline was not detected in milk during the metabolism study, these local milkshed case
assumptions are calculated using the one-half the Limit of Detection value.
' The concentrations are assumed to be zero, since under typical risk scenario animals are not assumed to
consume potato waste.                                             <

  c.     Occupational and Residential

        At this time, there are no prSducts containing chlorpropham
  intended for residential use. Therefore, the Agency is not conducting a
  residential exposure assessment. An occupational exposure assessment
  is required for an active ingredient if (1) certain toxicological criteria are
  triggered  and (2) there is potential exposure to either handlers (mixers
  loaders, applicators) during use of the chemical or to persons entering'
  treated sites after application is complete.

  Acute Toxicity:  Studies for acute toxicity indicate that chlorpropham is
  classified as category HI for acute oral toxicity, category IV for acute
  dermal toxicity, category IV for skin irritation potential, and category III
  for eyeirritation potential. It is riot classified as a skin sensitizer.
  Inhalation toxicity data were waived because chlorpropham technical
  cannot be prepared and tested in a respirable form.  Based on acute
 toxicity, the criteria for performing an exposure assessment are not met.

  Short Term and Intermediate Toxicitv- Short term toxicity is evaluated
 based on exposure to the test substance for 1 to 7 days. The Agency
 determined that the primary route of occupational exposure is dermal.
 The chlorprppham toxicology database does not include a short term
 study with a NOEL derived from dermal exposure.  Neither does the
 database include a dermal absorption.study.

        Intermediate term toxicity is evaluated based on exposure to the
 test substance for 1 week to several months.  The 21-day dermal study
 discussed previously regarding subchronic toxicity produced a NOEL
 value of 500 mg/kg/day (MRID 41899901).  The effects in this study
 were increased reticulocytes and possibly an increase in spleen weight
 (relative to brain weight),  the Agency decided that the intermediate
 toxicity is of concern arid warranted assessing the potential for exposure
 to handlers or persons entering treated sites post-application.  Therefore
 this NOEL value was used in the occupational risk assessment.

 Potential for Handler Exposure: The Agency has determined that there
 is potential exposure to mixers, loaders, applicators, or other handlers
 during usual use patterns associated with chlorpropham. The,Agency is
 specifically coneeraed.about potential exposures to workers who mix
 and load liquids and/or apply  chlorpropham using low pressure sprayers
 (i.e. hand held sprayers and groundboom sprayers).  Exposure data are
not available for the indoor application of chlorpropham on potatoes
(sprayed while the potatoes are on washer^ollers or through a forced-air
                      19

-------
                     distribution method).  In the indoor (potato) setting, workers wear full-
                     face oxygen-supplied respirators since there is little oxygen in potato
                     storage chambers during application (citation of information from
                     registrant).  Further, a closed-delivery system is employed for the
                     forced-air distribution use.  Due to the nature of the indoor use
                     practices, worker exposure in the indoor (potato) setting is not expected
                     to exceed that of workers involved in the outdoor crop treatment of
                     Easter lilies or spinach.

                     Potential for Post-Application Exposure: The Agency has determined
                     that there is potential exposure to persons entering treated sites after
                     application is complete.  The Agency has some concerns about both
                     post-application dermal exposures in all use sites and post-application
                     inhalation exposures following the forced-air distribution application at
                     stored potato sites.

                    Handler Exposure Assessment: Because chlorpropham has intermediate
                    toxicity concerns and the potential for exposure to handlers exists, an
                    occupational exposure assessment for handlers  (for outdoor uses) was
                    performed. However, there are no data available to evaluate the
                    potential exposure to handlers during the application of chlorpropham
                    into indoor potato storage facilities.

                          Table 4 below presents the assumptions that were used in the
                    occupational exposure assessment for handlers.

                 1987. At that time, no toxicological criteria had been triggered for '
                 chlorpjropham. A rough estimate of the exposure to post-application
                 workers was made based on the exposure values available in the handler
                 assessment. These rough estimates were used to assess the risk to
                 workers posed by post-application exposure. However, there are no

                 chlorprppham  following an application into indoor potato storage
                 facilities, since technical  chlorpropham cannot be formulated into a
                 material that is respirable by laboratory animals.

3.    Risk Assessment

      a.     Dietary

      Acute Dietary Risk  The endpoint selected for acute dietary risk
      assessment was based on the findings observed in a developmental
      toxicity study in the rabbit (MRID 00129940).  The effects of concern
      were increased resorption and post implantation loss (LOEL 500
      mg/kg). The NOEL was 250 mg/kg/day. The primary source of dietary
      exposure to chlorpropham is via potatoes (the tolerance for which is
      hereby being revised from 50 ppm to 30 ppm). No feed/food additive
      tolerances have been established. It is anticipated that acute dietary
      exposure will be significantly lower than 2.5 mg/kg/day, which is the
      exposure that would trigger a concern based on effects noted at the
      LOEL.  The basis for this is the relatively high NOEL in conjunction
      with the fact that it is used on so few crops (i.e., potatoes at 30 ppm and
      spinach at 0.3 ppm). Therefore, an acute dietary risk assessment was
      not necessary.

      Chronic Dietary Risk:  The chronic dietary analysis used a Reference
      Dose (RfD) of 0.05 mg/kg bwt/day:, based on an NOEL of 5 mg/kg
      bwt/day and an uncertainty factor of 100. The NOEL is taken from a
      chronic toxicity study in dogs (MRID  42189501) which demonstrated
      thyroid toxicity in males and females and other effects at 50~~mg/kg
      bwt/day (RfD/Peer Review Report of Chlorpropham, 10/24/94).

            USDA Pesticide Data Program Summary of 1992 Data (PDF
      data) show that .chlorpropham residues are found on 60% of potatoes.
      Since all treated potatoes would be expected to have detectable
      concentrations (the limit of detection for the PDP data is less than or
      equal to 13 ppb), the Agency estimated that 60% of the potatoes are
      treated. This information was corroborated by information supplied by
      the National Potato Council.

            Although the existing tolerance of chlorpropham on potatoes is
      50 ppm, current data indicate that the tolerance should be reduced to 30
      ppm and expressed in terms of chlorpropham per se. Therefore, the
      dietary risk from potatoes in this risk analysis was conducted assuming
      potato residues at both the 50 ppm and 30 ppm tolerance levels.

            Three DRES chronic analyses for chlorpropham were conducted
      in order to estimate risk resulting from different potato residue values
      and interim tolerances. For each analysis, both Theoretical Maximum
                           22

-------
                    Residue Contributions (TMRCs) and Anticipated.Residue Contributions
                    (ARCs) were calculated for the overall U.S. population and 22
                    population subgroups. The TMRCs assume that 100% of all crops are
                    treated and have chlorpropham residues. The ARCs assume that only
 .,'.''            60% of all potatoes are treated and have chlorpropham residues.  The
                    exposure estimates were then compared to the RfD for chlorpropham to
      ;     "         calculate estimates of chronic dietary risk.  ,-                        •....:

                           A comparison of Analysis I and II shows that the contribution to
                    chronic dietary risk from spinach (which is only one of many existing
                    interim tolerances) is negligible. The chronic dietary risk estimate is
                    driven by the level of the potato residue. .Since tolerance levels
                    represent upper bound residue limits, the chronic dietary risk estimates
                    would be lower if refined (average) residues were used in these
                    calculations. However, the U.S. population and all DRES subgroups ,
                    have exposures for,chronic dietary risk below the RfD in the analysis
                    assuming;reassessed (30 ppm) tolerance level residues are on60% of all
      v            potatoes (see table 10).  Therefore,  the development of more refined
                    anticipated residues was not required.  The three analyses are shown
                    below.  • '  .  '                        ..'.•"-"

                   Dietary Cancer Risk:  No data are currently available on the cancer
                   potency of the 3-chloroaniline metabolite.  Therefore, the dietary cancer
                   risk for the 3-chloroaniline metabolite has been estimated using the
                   cancer potency factor '(Q*,) of 6.38 x 1O'2 (mg/kg/day)'1 for the 4-
                   chloroaniline or para-chloroaniline isomer.

                          Anticipated residues for the 3-chloroaniline used in this risk
                   assessment are listed in table 3 of this document.  Since average
                   residues are usually considered appropriate for carcinogenic risk
                   estimates and the term "local milkshed" applies primarily to local use of

                   anticipated residues for potatoes (0.059 ppm) and assumed no residues
                   in meat and milk commodities. It is assumed in this scenario that no

                         The second scenario, termed the "local milkshed" scenario, used

                   residue for milk of 0.002 ppm  and a residue of 0.039 for beef liver. This
                   scenario assumes that processed potato waste is fed locally to-livestock/
                   and that food commodities derived from these livestock are distributed
                   locally. The upper bound carcinogenic risk from this scenario is

                   Characterization of Dietary Cancer Risk:  The estimated dietary cancer
                   risk as described above, exceeds the 1 x lO^6 estimate of individual
                   excess lifetime cancer risk generally considered to be negligible.
                   However, the Agency believes'the risk may be overestimated The
                                        25

-------
 Agency evaluated the weight-of-the-evidence for the carcinogenic
 potential of chlorpropham and concluded that chlorpropham should be
 classified as Group E. Nonetheless, due to the structure activity
 relationship of the chlorpropham metabolite, 3-chloroaniline, to 4-
 chloroaniline (which has a cancer potency factor C^*), the Agency
 expressed concern for potential carcinogenicity of 3-chloroaniline.
 Therefore, the 4-chloroaniline Qj* was used as a surrogate for 3-
 chloroaniline to gauge any potential risk from 3-chloroaniline.

       Substitution of aromatic amines such as aniline with  an electron
 donating adduct such as chlorine in either the ortho (1) or para (4)
 position relative to the amino group has been shown to result in greater
 cancer potency than observed for the parent compound (Amdur et al,
 1991).  Substitution in the meta (3) position is not likely to cause
 increased potency.  There is no way to quantify how much less potent
 this metabolite may be,  Therefore, the use of the Ch* from a para (4)
 substituted aniline (4-chloroaniline) to estimate the cancer risk from a
 meta (3) substituted aniline (3-chloroaniline) was generally agreed by
 OPP toxicologists to potentially overestimate the risk.  However, in the
 absence of a Qj* for 3-chloroaniline,  OPP used the best available cancer
 potency factor, i.e., the 4-chloroaniline Ch*. Additional factors which
 are also believed to potentially contribute to overestimation of the
 dietary cancer risk include:

 •      While 3-chloroanilirie was identified in the Sprague-Dawley rat
       as a metabolite of chlorpropham (MRID 42006901), 4-
       chloroaniline was not.

 •      There is a lack of target or sije concordance between
       chlorpropham and 4-chloroaniline in carcinogenicity  studies.
       The Agency concluded that chlorpropham should be classified as
       Group E (evidence of non-carcinogenicity for humans). This
       classification was supported by: 1) a lack of carcinogenic
       potential demonstrated in mice and 2) the increase in  benign
       Leydig cell tumors in Sprague-Dawley rats which occurred only .
       at a dose in excess of the maximum tolerated dose;

•      The Q!* for 4-chloroaniline was derived from a National  >
       Toxicology Program two-year carcinogenicity study in F344/N
       rats.  In this study, 4-chloroaniline was administered by gavage
       at 0, 2, 6, or 18 mg/kg for 103 weeks.  The Qt* was based on
       spleen sarcoma incidences in male rats'.

       ;              •      Mutagenicity testing indicates that 3-chloroaniline and 4-
                            chloroaniline are mutagenie in in vitro tests. These mutagenicity
                          •  test have about a 50 to 70 percent correlation (depending on how
                            the data are,compared) with carcinogenicity studies in rats and/or
                            mice.  The 3-chloroaniline structure is less reactive than 4-
                            chloroaniline, because of the position of the chlorine on the
                            benzene ring. Thus, 3-chloroaniline would be expected to be
              .       '       less carcinogenic. However, there is no adequate way to
                            quantitate this structure activity relationship at this time.

                            Cancer dietary risk from spinach is considered to be insignificant
                     because of the small dietary contribution from spinach and negligible
                     residues.

                     b.     Occupational and Residential


                           At this time, there are no products containing chlorpropham
                     intended for residential use. Therefore, the Agency is not conducting a
  ;                   residential risk:assessment.


                    Handler Risk: Margins of Exposure (MOEs); a ratio of the estimated
                     exposure level to the NOEL of 500 mg/kg/day from a 21-day dermal
                     study, were only calculated for occupational handlers in high exposure
                    potential scenarios. The resulting MOEs are all greater than 100,
                    indicating only minimal concerns. Table 11 provides the MOEs for

Dermal exposure is based on PHED clothing scenario for long pants, long-sleeved shirt, and no gloves.
A 50 percent protection factor was applied to the no glove data for the use of chemical resistant gloves.
It was assumed that 50 percent of the total dermal exposure was to the hands [i.e., total dermal exposure
= 0.3 mg/lb ai, hand exposure = 0.15 mg/lb ai (which becomes 0.075 mg/lb ai after the 50% reduction in
dermal exposure due to gloves) and the remaining dermal exposure = 0.15 mg/lb ai].  The PHED grades
for this scenario are acceptable and the number of replicates per body part are 14+. There is a high
confidence in this exposure data.     '

A 50 percent protection factor was applied to the no glove data for the use of chemical resistant gloves.
A 50 percent protection factor was applied to the actual hand exposure data because 102 mg/lb ai of the
103 mg/lb ai total dermal exposure was for the non-protected hands. The PHED grades are B, C, arid !
and the number of replicates ranged from 25 to 95. There is low to medium confidence in this exposure
data.


               Risk from Post-Application Exposures:  The Agency has determined
               that post-application exposures do not appear to pose an unreasonable
               risk to individuals entering treated areas, provided entry is not permitted
               immediately following application. Therefore, for all juses within the
               scope of the WPS (spinach and Easter lilies), a restricted-entry interval
               (REI) of 12 hours is required and personal protective equipment for
               workers  who enter the treated area before the REI is expired.

                      The 12-hour post-application entry restriction for chlorpropham
               does not apply to uses outside the scope of the WPS for agricultural
               chemicals. The predicted degree of exposure by such uses  do not
               warrant the same risk mitigation measures required for users  covered by
               the WPS.                   .

c.
              For f9rced-air distribution applications, the Agency is
       prohibiting entry until either a totalof two hours of mechanical
       ventilation (fans, etc.) or four hours of passive ventilation (windows,
       vents, etc.) have occurred: The ventilation time may be interrupted, 'i.e.,
       the time may be accumulated at sporadic intervals, such as 15 minutes '
   ,    ofv?ntilation following by a period with no ventilation, until the total
       required ventilation time has accumulated. This entry prohibition is due
       to concerns about exposures to airborne aerosols composed of

                           Only hydrolysis data have been required iu iiupport the indoor
                     use of this chemical on stored potatoes. Hydrolysis data indicate that
                     chlorpropham is stable to hydrolysis at an environmental pH.  Since it is
                     unlikely to be exposed to other routes of degradation indoors, it is likely
                     to persist indoors.

IV.    RISK MANAGEMENT AND REREGISTRATION DECISION

       A.    Determination of Eligibility

             1.     Eligibility Decision

                    Section 4(g)(2)(A) of FIFRA calls for the Agency to determine, after
             submission of relevant data concerning an active ingredient, whether products
             containing the active ingredient are eligible for reregi strati on.  The Agency has
             previously identified and required the submission of the generic (i.e. active
             ingredient specific) data required to support reregistration of products
             containing chlorpropham as an active ingredient. The Agency has completed
             its re/iew of these generic data, and has determined that the data are sufficient
             to evaluate the risks associates with the primary indoor use on stored potatoes.

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

 B.     Regulatory Position

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

       1.     Tolerance Reassessment

     "  Tolerances Listed Under 40 CFR S18Q  181 • The tolerances listed in 40 CFR   -
       ง 180.181 for post-harvest potatoes and soybeans are currently expressed in
       terms  of the  combined residues of chlorpropham and 1 -hydroxy-2-propyl-3-
,      -chlorocarbanilate. The  tolerance expression for post-harvest potatoes will be
       revised to reflect residues of chlorpropham per se. Sufficient data were
                                   33

-------
 available to assess the adequacy of the established tolerance for post-harvest
 potatoes. The data indicate that the tolerance may be reduced from 50 ppm to
 30 ppm.  The following treatment rates should not be exceeded:

 •    '  aerosol fog at 0.022 lbsai/1000 Ibs potato in each of two applications
        90 days apart followed by direct spray at 0.0104 Ibs ai/1000 Ibs potato;
        or

 •      aerosol fog at 0.033 Ibs ai/1000 Ibs potato and a second aerosol fog 140
        days later at 0.017 Ibs ai/1000 Ibs potato.

        Because the soybean use is no longer being supported, the soybean
 tolerance of 0.2 ppm will be proposed for revocation.

 Tolerances Listed Under 40 CFR SI80.319 (interim tolerancesV The
 tolerances listed in 40 CFR ง180.319 for chlorpropham are expressed in terms
 of residues of chlorpropham per se.

        Insufficient data are available to assess the adequacy of the interim
 tolerances for milk, and the fat, meat, and meat byproducts of cattle, goats,
 hogs, horses, and sheep. Data from a ruminant feeding study are due to the
 Agency by October, 1995.  Subsequent to the review of that data, appropriate
 tolerance levels for these commodities will be determined and the interim
 tolerances, will be revoked. Tolerances for combined residues of chlorpropham
 and 4-hydroxychlorpropham-O-sulfonic acid in these commodities will then be
 proposed under 40 CFR ง 180.181.

       Because the use.of chlorpropham on the following crops is no longer
 being supported, the corresponding interim jplerances will be  proposed for
 revocation:  alfalfa, alfalfa hay, beans (dry and succulent), blackberries,
 blueberries,  carrots, clover, clover hay, cranberries, garlic, grass, grass hay,
 onions, peas (dry and succulent), raspberries, rice grain, safflower seed, sugar
 beet roots and tops, and tomatoes. Additional data are required to support the
 interim tolerance for chlorpropham on spinach. A tolerance under 40 CFR
 ง180.181 must be proposed.

       The Agency has determined that tolerances for poultry commodities are
not required since potato commodities are not a significant poultry feed item.
Therefore, the interim tolerances for eggs, and the fat, meat, and meat
byproducts of poultry will be proposed for revocation.

  Processed. Food (40 GFR ง185^) and Feed (40 GFR S186YToleranr.es  No
  food/feed additive tolerances have been established for chlorpropham. An
  adequate potato processing study has-been conducted for chlorpropham. The
  study indicates that chlorpropham residues in potato peels are 2.4 times higher
  than the residues for the entire raw potato. The concentration of chlorpropham
  in peels suggests that an additional (higher) pesticide tolerance (under FFDCA
  Sect."409) might be needed for processed potato waste, a cattle feed item  Such
  tolerances are only necessary when residues in ready-to-eat processed food or
  animal feed appreciably exceed the raw food tolerance.

        Although chlorpropham concentrates in potato peels, the Agency
 believes for various reasons that residues in processed potato waste are not
 likely to appreciably exceed the reassessed raw agricultural tolerance of 30
 ppm.  Therefore, a processed feed tolerance is not required under FFDGA Sect.
 409.. The Agency is requiring residue data from processed potato waste to;
 confirm this presumption.   -
 ; -   -         . ' .   •      .   .         "--*".."•__,    •       -^-  .    ' ...  ,
       The Agency does not find it necessary to make a determination whether
 processed potato waste is ready to eat.in this situation because calculated
 residues of chlorpropham in this commodity do not significantly exceed the
 FFDCA 408 reassessed tolerance.  Listed below are the Agency's assumptions
 regarding and calculation ofan expected processed potato waste residue.

 Calculation of Expected Residues for Processed Potato Waste- The Agency
 protocol for conducting potato processing studies does not completely reflect
 commercial practices because data  on actual processing waste do not need to be
 generated.  Because processed potato waste contains more water than raw
 potatoes, a dilution factor must be used in calculating expected processed
 potato waste residues (see Table II update in the Agency's Pesticide
 Reregistration Rejection Rate Analysis: Residue Chemistry Follow Up, June
 1994). The added water arises, at least in part, from washing potatoes during
 processing.  Therefore, the calculation of expected processed potato waste
 residues takes  into account the following components:

 •     24-5 Ppm - the highest residue of chlorpropham on raw potatoes in the
       potato field trial    .      ^,    -         v;         ,   ,;      ,

 •    2.4X.=. the average concentration factor in potato peels from the
      processing study ,

•     the assumption that the dry matter content of potato peels is the same as
      that for whole raw potatoes           •-'                •.'.
                            35 •-

-------
 •      0.12/0.2 = a dilution factor based upon the ratio of the dry matter
        contents (as percentages) of processed potato waste to whole raw
        potatoes

 The expected residue in potato waste is calculated as follows:

        24.5 X 2.4 X 0.12/0.2 = 35.28 ppm

        This 35.28 ppm chlorpropham expected residue in processed potato
 waste is not significantly above the reassessed 30 ppm raw potato tolerance
 (the factor is 1.2). The Agency believes that even this 35.28 ppm estimate is
 conservative since there are a variety of additional factors which would tend to
 decrease the estimate of chlorpropham levels in processed potato waste. These
 factors are listed below:

 •     Processed potato waste is comprised not solely of peel, but also of
       culled potatoes, clarifier and other wastes, culled french fries/processed
       products, etc.  These items would be expected to have lower
       chlorpropham concentrations than peel and would thus tend to lower the
       chlorpropham residues found in the processed waste product.

 •     Potatoes processed commercially are expected to undergo a more
       rigorous washing than the gentle rinsing used in the processing study
       evaluated by the Agency. This washing step is expected to further
       decrease chlorpropham residues.

 •     Per industry sources, potatoes are almost exclusively peeled by means
       of a "steam-peeling" procedure, rather than the simple hand peeling
       used in the evaluated processing study. This added heat may accelerate
       chlorpropham loss/degradation.

 •     The Agency utilizes the highest average field trial (HAFT) in
       calculations when more than one field trial has been submitted. -Since
       the Agency only has one relevant chlorpropham field trial from a single
       location, the highest reported concentration (24.5 ppm) was used.  If
       average residues were considered, the concentration in the livestock
       feed would likely be significantly lower.                              >

       It should be noted that revoking the above tolerances may impact the
 importation into the United .States of corresponding food items bearing
'Chlorpropham residues.  Any interested party who wishes to maintain a
 chlorpropham residue tolerance for importation purposes in the absence of a
 registered use should contact the Agency. In general, the Agency requires the
 same product chemistry and toxicology data to support an import tolerance as
 are required to support FIFRA registrations. The Agency also requires residue
 chemistry data representative of g-rwing conditions in the exporting countries.
                             38

-------
  2.     Codex Harmonization

        There are no Codex Maximum Residue Limits (MRLs) established or
  proposed for residues of chiorpropham. Therefore, there are no questions with
  respect to compatibility ofU.S . tolerances with Codex MRLs.

  3.     Restricted Use  Classification

        Chlorpropham as currently registered does not trigger the criterion for a
  restricted use classification.                                  ,       '

  4.     Reference Dose

        The Agency established a Reference Dose (RfD) of 0.05 mg/kg
 bwt/day for a chronic dietary, exposure risk assessment based on the no effect
 level from a chronic feeding study in dogs.  This  RfD was not exceeded for any
 subgroup of the U.S. population in the scenario where residues  on 60% of all
 U.S. potatoes were assumed to be at the reassessed potato ,tolerance value of 30

Cancer Risk
 5.
       Chlorpropham per se has been tested for carcinogenicity and
 determined to be, a group E chemical (evidence of non-carcinogenicity for
 humans) according to the Agency's cancer classification guidelines.  However,
 3-chloroaniline, one of chlorpropham's metabolites, is structurally similar to a '
 known carcinogen, 4-chloroaniline.  Since there are no cancer data available on
 3-chloroaniline, the Agency believed it appropriate to perform a risk
 assessment using^chloroaniline's cancer potency (Q^) to gauge any potential
 risk from 3-chloroaniline.

       The resulting values from the extrapolated risk assessment were in the
 range of 3 to 4 x W6. These risk estimates exceed the 1 x 10* estimate of
 individual excess lifetime cancer risk generally considered to be negligible.
 However, the Agency believes this assessment is an overestimation of risk for
 3-chloroaniline for the reasons discussed in chapter III1 of this document.  In
 addition, the uncertainties inherent in performing this risk assessment, based on
the potency .of a structural analog rather than the compound present, are great
The Agency believes it is not likely that 3-chloroaniline as a metabolite of
chlorpropham is posing a risk of regulatory concern.
                            39

-------
 6.     Endangered Species Statement

        The primary use of chlorpropham on stored potatoes is an indoor use.
 This use is unlikely to result in harm to federally listed threatened or
 endangered species. However, if the outdoor uses of chlorpropham are
 maintained, the Agency will address those uses in the Endangered Species
 Protection Program, a developing program to identify all pesticides whose use
 may cause adverse impacts on endangered and threatened species.  This
 program is designed to implement mitigation measures that will address the
 adverse impacts.  The program would require use modifications or a generic
 product label statement, requiring users to consult county-specific bulletins.
 These bulletins would provide information about specific use restrictions to
 protect endangered and threatened species in the county.  Consultations with
 the Fish and Wildlife  Service may be necessary to assess risks to newly listed
 species or from proposed new uses.

       The Agency plans to publish a description of the Endangered Species
 Program in the Federal Register in the future. Because the Agency is taking
 this approach for protecting endangered and threatened species, it is not
 imposing label modifications at this time through the RED.  Rather, any
 requirements for product use modifications will occur in the future under the
 Endangered Species Protection Program.

 7.     Worker Protection Requirements
                                                        . *     i

 Uses Within the Scope of the Worker Protection Standard- The 1992 Worker
 Protection Standard for Agricultural Pesticides (WPS) established certain
 worker-protection requirements (personal protective equipment, restricted entry
 intervals, etc.) to be specified on the labels of all products that contain uses
 within the scope of the WPS.  Uses within the scope of the WPS include all
 commercial (non-residential) and research uses on farms, forests,  nurseries, arid
 greenhouses to produce agricultural plants (including food and feed crops). Of
 the current chlorpropham use sites, only spinach and Easter lilies are within the
 scope of the WPS.

 Those uses that are outside the scope of the WPS include uses:

 •      on the portions of agricultural plants that have been harvested, such as
       on stored potatoes, and                            ,

ป      on plants, such  as ginkgo trees, that are in ornamental gardens, parks,
       golf courses, and public or private lawns and grounds and that are
       intended only for decorative or environmental benefit.

Personal-Protective Equipment/Engineering Controls for Handlers

WPS and nonWPS Uses: At this time, there are no engineering control
requirements, such as closed systems, currently required on labeling for
chlorpropham  products,  .

       For each end-use product, PPE requirements  for pesticide handlers will
be set during reregi strati on in one of two ways:
1.
If EPA has no special concerns about the acute or other adverse/effects
of an active ingredient, the PPE for pesticide handlers will be
established based on the acute toxicity of the end-use product.  For
occupational-use products, PPE will be established using the process
described in PR Notice 93 -7 or more recent EPA guidelines,.
       ...         ^ -         ..      /      _.,....             f.  |

If EPA has special concerns about an active ingredient due to very high
acute toxicity or to certain other adverse effects, such as allergic effects,
cancer, developmental toxicity, or reproductive effects:
                            41

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

        •     These minimum PPE requirements must be compared with the
              PPE that would be designated on the basis of the acute toxicity
              of each end-use product.
        •     The more stringent choice for each type of PPE (i.e., body wear,
              hand protection, footwear, eyewear, etc.) must be placed on the
              label of the end-use product.

        There are special lexicological concerns from dermal exposure to  '
 chlorpropham that warrant the establishment of active-ingredient-based h* Hl.er
 PPE requirements.  The MOEs were calculated as being acceptable for both
 WPS and nonWPS  handlers based on an adjustment simulating the wearing of
 chemical-resistant gloves by handlers. A requirement for chemical-resistant
 gloves is being required as minimum (baseline) PPE for all. occupational
 handlers.                                                             !,

       For applications of chlorpropham as an aerosol, the Agency is requiring
 use of a respirator for handlers who must enter an enclosed treated  site during
 either application or the ventilation period. Although inhalation data were
 waived because technical chlorpropham cannot be prepared and tested in a
 respirable form, the existing toxicology data indicate there are no special
 inhalation concerns based on extrapolations from oral data. The Agency
 believes it prudent to require a respirator when entering during application or
 ventilation to minimize exposure.

       The type of respirator must be specified on each chlorpropham end-use
 product labeled for application through an aerosol generator. The type of
 respirator required depends on the product ingredients other than
 chlorpropham.  Since the vapor pressure of chlorpropham is low, a
NIOSH/MSHA dust/mist filtering respirator is sufficiently protective for
 chlorpropham aerosols. However, if other ingredients in the end-use product
(either actives or inerts) have a high vapor pressure (eg. methanol),  a respirator
with an organic-vapor absorbing component (cartridge or canister) plus a
dust/mist filtering component is required.

  Entry Restrictions for Occupational-Use Products (WPS Uses): At this
  time, some registered uses of chlorpropham are within the scope of the Worker
  Protection.Standard for Agricultural Pesticides (WPS) and some are outside the
  scope of the WP,S.

  Restricted Entry Interval: Under the Worker Protection Standard (WPS)
  interim restricted entry intervals (REI) for all uses within the scope of the WPS
  are based on the acute toxicity of the active ingredient. The toxicity categories
  of the active ingredient for acute dermal toxicity; eye irritation potential, and
  skin irritation potential are used to determine the interim WPS REI. If one or
  more of the three acute toxicity effects are in toxicity category I, the interim
  WPS REI is established at 48 hours. If none of the acute toxicity effects are in
  category I,  but one or more of the three is classified as category  II, the interim
 WPS REI is established at 24 hours: If none of the three acute toxicity effects
 are in category I or H, the interim WPS REI is established'at 12  hours. A 48-
 hour REI is increased to 72 hours when an organpphosphate pesticide is *
 applied outdoors in arid areas. In addition, the WPS specifically retains two
 types of REI's established by the Agency prior to the promulgation of the WPS'
 (1.) product-specific REPs established on the basis of adequate data  and (2)
 interim REI's that are longer than those that would be established under the	


       For occupational end-use products containing chlorpropham as an
 active ingredient, the Agency is establishing a 12-hour restricted-entry interval .
 for each use of the product that is within the scope of the Worker Protection
 Standard for Agricultural Pesticides (WPS).  The basis for this requirement is
 that chlorpropham is categorized as toxicity category III for eye irritation
 potential and toxicity category IV for acute dermal toxicity and for skin
 irritation potential, and EPA has no special concerns about other  adverse
 effects (NOEL for intermediate-term exposures based on a 21-day dermal studv
 in rabbits).                                                       ;      •*•

 Early-Entry PPE: The WPS establishes very specific restrictions on entry by
 workers to areas that remain under a restricted-entry interval if the entry
 involves contact with treated surfaces Among those restrictions  are a
 prohibition of routine entry to perform hand labor tasks and the requirement

 entry interval are based on the toxicity concerns about the active ingredient.
 The requirements are set in one of two ways.

 1.     If EPA has no special concerns about the .acute or other adverse effects
       of an active ingredient, it establishes the early-entry PPE requirements
       based on the acute dermal toxicity, skin irritation potential, and eye
       irritation potential of the active ingredient.

 2.     If EPA has special concerns about an active ingredient due to very high
       acute toxicity or to certain other adverse effects, such as allergic effects,
       cancer, developmental toxicity, or reproductive effects, it may establish
       early-entry PPE requirements that are more stringent than would be
       established otherwise.                 '       ,       ,      .

       Since chlorpropham is classified as category HI for eye irritation
 potential and as category IV for acute dermal toxicity and for skin irritation
 potential, and EPA has no special concerns about other adverse effects, the PPE
 required for early entry is:  coveralls, chemical-resistant gloves, shoes, and
 socks.

 Post-Application/Entry Restrictions

 NonWPS Uses                                                   .

       At this time some registered uses of chlorpropham are outside the scope
 of the Worker Protection Standard for Agricultural Pesticides,(WPS).

       For forced-air distribution applications (due to inhalation concerns), the
 Agency is prohibiting entry except to persons equipped with the appropriate
 handler PPE until either a total of two hours*of mechanical (fans,  etc.)
 ventilation or four hours of passive (windows, vents, etc.) ventilation has
 occurred, or until such time as 10 complete air exchanges have occurred. The
 ventilation time may be interrupted, i.e., the time may be accumulated at
 sporadic intervals, such as 15 minutes of ventilation followed by a period with
no ventilation, until the total required ventilation time has accumulated.

       Chlorpropham products which are labeled for application to potatoes on
a conveyor belt must contain the following statement:

       Following application, workers (e.g. baggers) must wear chemical-
       resistant gloves while potatoes are wet.
                             44

                        - However, registrants may chose instead to modify their labels to
                         conform to the above scenarios or submit additional information
                         showing why residues on  potatoes treated with their product

       2.     Labeling Requirements for Manufacturing-Use Products

             To remain in compliance witiiFIFRA, manufacturing use product (MP)
       labeling must be revised to comply with.aU current EPA regulations, PR
       Notices, and applicable policies. The MPlabeling must bear the following
       statement under Directions for Use:                ,                 ',.,',

             "Only for formulationlnto a herbicide/plant growth regulator for the
       following use(s):____ (fill blank only with those uses that are being ,
       supported by MP registrants)."

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

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

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

B.     End-Use Products                                       _.-;,-

    •'-!,'    Additional Product-Specific Data Requirements

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

             Registrants must review-previous data submissions to ensure that they
       meet current EPA acceptance criteria (Appendix-F; Attachment E) and if not,
       commit to conduct new studies.  If a registrant believes that previously
                                  47

-------
 submitted data meet current testing standards, then study MRID numbers
 should be cited according to the instructions in the Requirement Status and
 Registrants Response Form provided for each product.

       Since manufacturing use registrants may not support the uses of
 chlorpropham on spinach, Easter lilies, or ginkgo trees, end use registrants may
 be required to conduct the data listed under the Manufacturing-Use Products
 section above to maintain their registrations.  Within 90 days, registrants will
 have to commit to generate the data, volunteer to  cancel their products, or
 comply with Agency requirements by selecting other appropriate options in the
 Data Call In.
 2.     Labeling Requirements for End-Use Products

 Occupational/Residential Labeling           .
                      ป                   .

 PPE Requirements for Pesticide Handlers

       Sole-active-ingredient end-use products that contain chlorpropham
 must be revised to adopt the handler personal protective equipment
 requirements set forth in this section. Any conflicting PPE requirements on
 their current labeling must be removed.     ,             ,

       Multiple-active-ingredient end-use products that contain
 chlorpropham must compare the handler personal protective equipment
 requirements set forth in this section to the PPE requirements  on their current
 labeling and retain the more protective. For guidance on which PPE is
 considered more protective, see PR Notice 93-7.

 Products Intended Primarily for Occupational Use

 WPS and nonWPS uses

       Minimum (baseline) PPE requirements — The minimum (baseline)
 PPE for all WPS and nonWPS uses of chlorpropham is:

 Applicators and other handlers must wear:
 —chemical-resistant gloves*,

 * The glove statement for {active ingredientl is the statement established through the instructions in Supplement Three of
PR Notice 93-7.

       In addition, for all chlorpropham products that bear use-directions for
generating an aerosol in an aerosol generator or for using a forced-air
distribution method  of application, the following PPE restriction applies:

                            48

-------
  --From the start of application and continuing until the ventilation requirements
  listed on this labeling have been completed, for entry into the enclosed treated
  area, handlers must wear a long-sleeve shirt, long pants, shoes and socks, and a
  respirator.  The following type of respirator is appropriate to mitigate    '
  chlOrpropham inhalation exposure when the end-use product does not contain
  an inert ingredient which has a low vapor pressure:

  •     A dust/mist filtering respirator (MSHA/NIOSH approval number orefix
   ;     TX-21C).

        If the end-use product contains an inert, such as methanol,,which has a
 low vapor pressure, the type of respirator appropriate to mitigate the inhalation
, concerns for that end-use product is:

 •      A respirator with either an organic-vapor-removing cartridge with a
        prefilter approved for pesticides (MSHA/NIOSH approval  number
        prefixTC-23C), or a canister approved for pesticides,(MSHA/NIOSH
        approval number prefix TC-14G).

        If the enclosed area contains less than 19.5 percent oxygen,'the
 respirator must be one of the following types:

 •      A supplied-air respirator (MSHA/NIOSH approval number prefix TC-
        19G) OR a self-contained breathing apparatus (SCBA) (MSHA/NIOSH
        approval number prefix TX-13F).      .

Actual end-use product PPE requirements - The PPE that would otherwise
be established based on the acute toxicity of each end-use product must be
compared to the minimum (baseline) personal protective equipment, if any
specified above. The more protective PPE must be placed on the product
labeling. For guidance on which PPE is considered more protective see PR
Notice 93-7.                              "•  ' '              '
                                                       >            (

Placement in labeling - The personal protective equipment  must be placed on
the endwise product labeling in the,location specified in PR Notice  93-7 and the
format and language of the PPE requirements must be the same as is specified
in PR Notice 93-7.,

Entry Restrictions

Sole-active-ingredient end-use products that contain chlorpropham must be
revised to adopt the entry restrictions set forth in this section.  Any conflicting
entry restrictions on their current labeling must be removed.
                            49

-------
 Multiple-active-ingredient end-use products that contain chlorpropham must
 compare the entry restrictions set forth in this section to the entry restrictions on
 their current labeling and retain the more protective. A specific time-period in
 hours or days is considered more protective than "sprays have dried" or "dusts
 have'settled."

 Products Intended Primarily for Occupational Use

 WPS uses

 Restricted-entry interval - A 12-hour restricted entry interval (REI) is
 required for uses within the scope of the WPS (see PR Notice 93-7) on all end-
 use products (see tests in PR Notices 93-7 and 93-11). This REI must be
 inserted into the standardized REI statement required by Supplement Three of
 PR Notice 93-7.

 Early-entry personal protective equipment (PPE) —

 The PPE required for early entry is:
 —coveralls,
 —chemical-resistant gloves,
 —shoes plus socks

       Handler PPE, in addition to chemical resistant gloves,  will be
 established at the time of product reregistration based on the toxicity of the
 end-use product.  However, at a minimum, PPE for handlers involved in
 chlorpropham application for WPS uses will be established at an equivalent
 protection level (i.e. long-sleeves, long pants, shoes and socks).

 Placement in labeling ~ The REI must be inserted into the standardized REI
 statement required by Supplement Three of PR Notice 93-7. The PPE required
 for early entry must be inserted into the standardized early entry PPE statement
 required by  Supplement Three of PR Notice 93-7.

 NonWPS uses

 Entry restrictions —

For aerosol or forced-air distribution applications:                      ป
 "Do not enter or allow any person, other than a person equipped with the
appropriate handler personal protective equipment including the appropriate
respirator, to enter the treated area until the area has been ventilated.
Ventilation may be for either a total of two (2) hours with fans or other
                             50


-------
  mechanical ventilation or four (4) hours with windows, vents, or other passive
  ventilation, or until such time that there have been 10 complete air exchanges:
  The ventilation time may be interrupted, i.e., the time may be accumulated at
  sporadic intervals, such as 15 minutes of ventilation followed by a period with
  no ventilation, until the total required ventilation time has accumulated."

  Chlorpropham products which are labeled for application to potatoes on a
  conveyor belt ;must contain the following statement:
  Following application,.workers (e.g. baggers) must wear chemical-resistant
  gloves while potatoes are wet,

  Placement in labeling --

-  If WPS uses are also on label: Follow the instructions in P_R Notice 93-7 for
  establishing, a Non-Agricultural Use Requirements box.and place the
  appropriate nonWPS entry restriction in that box.

  If no WPS uses are on label: Add the appropriate nonWPS entry restriction
  to the labels of all end-use products, except products primarily intended for
  residential use, in a section in the Directions For Use with the heading: "Entry
  Restrictions:"'

  Other Labeling Requirements

  Products Intended Primarily for Occupational Use

        The Agency is requiring the following labeling statements to be located
  on all end-use products containing chlorpropham that are  intended primarily for
  occupational use.
                          • *'       :      ^       "

 Application restrictions

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

 Engineering controls                     :

 "When handlers use closed systems or enclosed cabs in a manner that meets the
 requirements listed in the Worker Protection Standard (WPS) for agricultural
 pesticides,(40 CFR 170.240(d)(4-6), the handler PPE requirements may be
 reduced or modified as specified in the WPS,"
                             51

-------
 User safety requirements

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

       The Agency is requiring the following labeling statement to be placed
.on all chlorpropham end-use products which are labeled for use on ginkgo
 trees. This statement is considered adequate to preclude the possibility of
 residues in ginkgo nuts (a food item) since ginkgos are grown primarily as
 ornamentals in the United States.

 "Do not use on ginkgo trees which produce ginkgo nuts destined for human
 consumption."

 User safety recommendations

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

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

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

Residue Chemistry Labeling Requirements

       Unless registrants conduct additional residue data under guideline 171-
4(k), end use product labels must conform to the residue trial scenarios
presented below or show why potatoes treated according to their label, would
not be expected to have residues above the reassessed tolerance of 30 ppm.

Scenarios

•     Aerosol fog at 0.022 Ibs ai/1000 Ibs (0.0022 Ibs ai/cwt) potato in each of
      two applications 90 days apart followed by direct spray at 0.0104 Ibs
      ai/1000 Ibs (0.00104 Ibs ai/cwt) potato; or

"     Aerosol fog at 0.033 Ibs ai/1000 Ibs (0.0033 Ibs ai/cwt) potato and a
      second aerosol fog 140 days later at 0.017 Ibs ai/1000 Ibs (0.0017 Ibs
      ai/cwt) potato.
                            52

G.     Existing Stocks

       Registrants may generally distribute arid sell products bearing old
labels/labeling for 26 months from the date of the-issuance of this Reregistration
Eligibility Decision (RED). Persons other than the registrant may generally distribute
or sell such products for 50 months from the date of the issuance of this RED.
However, existing stocks time frames will be established case-by-case, depending on
the number of products involved, the number of label changes, and other factors. Refer
to "Existing Stocks of Pesticide Products; Statement of Policy"; Federal Register.

                         GUIDE TO APPENDIX C

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

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

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

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

a     Author. Whenever the author could confidently be identified, the Agency has
      chosen to show a personal author.  When no individual was identified; the
      Agency has shown an identifiable laboratory or testing facility as the author.
      When no author or laboratory could be identified, the Agency has shown the
      first submitter as the author.
      b.
      Document date.  The date of the study is taken directly from the document.
      When the date is followed by a question mark, the bibliographer has deduced
      the date from the evidence contained in the document.  When the date appears
      as (19??), the Agency was unable to determine or estimate the date of the
      document.                                   .         .
                                         75

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

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

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

(2)   Administrative number.  The next element immediately following the
      word "under" is the registration number, experimental use permit
      number, petition number, or other administrative number associated
      with the earliest known submission.
                    *                 .               '
                 f
(3)   Submitter. The third element is the submitter. When authorship is
      defaulted to the submitter, this element is omitted,

(4)   Volume Identification (Accession Numbers).  The final element in the
      trailing parentheses identifies the EPA accession number of the volume
      in which the original submission of the study appears. The six-digit
      accession number follows the symbol "CDL," which stands for
      "Company Data Library," This accession number is in turn followed by
      an alphabetic suffix which shows the relative position of the study within
      the volume.

 containing the active ingredient(s).  JEPA has concluded, as an exercise of its
 discretion, that it normally will not suspend the registration of a product which
 would qualify and continue to qualify for the generic data exemption in section
 3(c)(2)(D) of FIFRA. To qualify, all of the following requirements must be met:

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

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

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

       To apply for the Generic Data Exemption you must submit a completed
Data Call-In Response  Form; Attar.hmRnt 9  and all supporting documentation.
The Generic Data Exemption is item number 6a on the Data Call-In Response

Requirements Status and Registrant's Response Form.  Generic Data Exemption
cannot be selected as an option for product specific data.
                            93

-------
             If you are granted a Generic Data Exemption, you rely on the efforts of
       other persons to provide the Agency with the required data. If the registrant(s)
       who have  committed to generate  and submit the  required data fail to take
       appropriate steps to meet the requirements or are no longer in compliance with this
       Data 'Call-In Notice, the Agency will consider that both they and you are not in
       compliance and will normally initiate proceedings to suspend the registrations of
       both your and their product(s), unless you commit to submit and do submit the
       required data within the specified time.  In such cases the Agency generally will •
       not grant a time extension for submitting the data.

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

 Option 1. Developing Data —                              ~            .

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

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

       In addition, if the time frame for submission of a final report is  more than
 1 year, interim reports must be submitted at 12 month intervals from the date you
are required to commit to generate or otherwise address the requirement for the
study. In addition to the other information specified in the preceding paragraph,
at a minimum, a brief description of current activity on and the status of the study
                            95

-------
 must be included as well as a full description of any problems encountered since
 the last progress report.         ,

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

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

 Option 2. Agreement to Share in Cost to Develop Data  ~

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

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

       If you have made an offer to pay in an attempt to enter into ah agreement
 or amend an existing agreement to meet the requirements of this Notice and have
been unsuccessful, you may request EPA (by selecting this option) to  exercise its
                            96

-------
  discretion not to suspend your registration's), although you do not comply with
  the data submission requirements of this Notice.  EPA has determined that as a
  general  policy,  absent other relevant considerations, it will hot suspend the
  registration of a product of a registrant who has in good faith sought and continues
  to seek to enter into a joint data development/cost sharing program, but the other
  registrants) developing the data has refused to accept your offer. To qualify for
  this option, you must submit documentation to the Agency proving that you have
  made an offer to another registrant (who has an obligation to submit data) to share
  in the burden  of developing that data. You must also submit to the Agency a
  completed EPA Form 8570-32, Certification of Offer to Cost Share in the
 Development of Data. .In addition, you must demonstrate that the other registrant.
 to whom the offer was made has not accepted your offer to enter into a  cost
 sharing agreement by including a copy of your offer and proof of the other
 registrant's receipt of that offer (such as a certified mail receipt). Your offer must <
 in addition to  anything else, offer to share in the burden of producing, the data
 upon terms to be agreed or failing agreement to be bound by binding arbitration
 as provided by FIFRA section 3(c)(2)(B)(iii) and must not qualify this offer.  The
 other registrant must also inform EPA of its election of an option to develop and
 submit the data required by this Notice by submitting a Data Call-in Response.
 E2SS- and a Requirements Status and Registrant's Response Form committing to
 develop and submit the data required by this Notice.

       In order for  you to  avoid suspension under this option, you may not
 withdraw your offer to share in the burdens of developing the data. In addition
 the other registrant must fulfill its commitment to develop and submit the data as
 required by this Notice.  If the other registrant fails to develop the data or for some
 other reason is subjectito suspension, your registration as well as that of the other
 registrant will normally he subject to initiation of suspension proceedings, unless
 you commit to submit, and do submit the required data in the specified time frame
 In such cases, the Agency, generally will not grant a time extension for submitting
 thedata.  -            ,      ;      .•..-.'!..•-,..:.. s  ...'...,.-.  .    .'..:/-'","'.

 Option 4. Submitting an Existing Study —

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

      You  should be aware that if the Agency determines Jhat the study is not
acceptable, the Agency will  require you to comply with this Notice, normally
                            97

-------
without an extension  of .the required date of submission.   The Agency may
determine at any time that a study is not valid and needs to be repeated.

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

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

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

       c.     You must certify that each study fulfills the acceptance criteria for
      the Guideline relevant to the study provided in the FIFRA Accelerated
      Reregistration Phase 3 Technical Guidance and that  the study has been
       conducted according to the Pesticide Assessment Guidelines (PAG) or
      meets the purpose of the PAG (both available from NTIS).  A study not
       conducted according to the PAG may be submitted  to  the Agency for
       consideration if the registrant believes that the study clearly meets the
      purpose of the PAG. The registrant is referred to 40  CFR 158.70 which
      states the Agency's policy regarding acceptable protocols. If you wish to
      submit the study, you must, in addition to certifying that the purposes of
      the PAG are met by the  study, clearly articulate the  rationale why you
                            98

-------
        believe the study meets the purpose of the PAG, including copies of any
        supporting information or data. It lias been the Agency's experience that
    *    studies completed prior to January  1970 rarely satisfied the purpose of the
        PAG and that necessary raw, data are usually not available for such studies.

               If you submit an existing study, you must certify that the study '
        irieets all requirements of the criteria outlined above.          "

               If EPA has previously reviewed a protocol for a study you are
        submitting, you must  identify any action taken by the Agency on the
        protocol  and must indicate, as part of your certification, the manner in
        .w,hich  all Agency comments, concerns,  or issues were addressed in the
        final protocol and study.                                         .
         •  ;     ,         '      ,     -      .   -   - •  -    /•',,'-
              If you know of a study pertaining to any requirement in this Notice
        which does not meet the criteria outlined above  but does contain factual
        information regarding unreasonable adverse effects, you must notify the
        Agency of such a study. If such a study is in the Agency's files, you need
        only cite.it along with the notification. If hot in the Agency's files, you
        must submit a summary and copies as required by PR Notice 86-5.'   :

 Option 5. Upgrading aStudy -

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

       Do not  submit additional data for the purpose  of upgrading a study
 classified as unacceptable and determined by the Agency as not capable of being
upgraded.
                            99

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

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

       Option 6. Citing Existing Studies —                         .'.'•"

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

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

D.   .  REQUESTS FOR DATA WAIVERS                                       -
                                    	    —

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

       1-     Low Volume/Minor Use Waiver ~ Option 8 on the Requirements Status
       and Registrant's Response Form. Section 3(c)(2)(A) of FIFRA requires EPA to
       consider  the  appropriateness  of requiring data for low volume, minor use
       pesticides.  In implementing  this provision EPA considers as low volume
       pesticides only those active ingredient(s) whose total production volume for all
       pesticide registrants is small.  In determining whether to grant a low volume,
       minor use waiver the Agency will consider the extent, pattern and volume of use,
       the economic incentive to conduct the testing, the importance of the pesticide, and
       the exposure and risk from use of the pesticide. If an active ingredient(s) is used
                                                                        ' !     (

                                   100                                       .

-------
 for both high volume and low volume uses, a low volume exemption will not be
 approved.  If all uses of an active ingredient(s) are low volume and the combined
 volumes for all uses are also.low, then an exemption may be granted, depending
 on review of other information outlined below. An exemption will not be granted
 if any registrant  of the active ingredient(s) elects to conduct the testing.  Any
 registrant receiving a low volume minor use waiver must remain within the sales .
 figures in their forecast supporting the waiver request in order to remain qualified
 for such waiver. If granted;a waiver, a registrant will be required, as a condition
,of the. waiver, to submit annual sales reports. The Agency will respond to requests
 for waivers in writing.

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

       registered in this country but are-applied to sugar (cane or beet), coffee
       bananas, cocoa, and other such crops. Present the above information by
       year for each of the past five years.^                       •'.,..',.

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

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

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

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

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

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

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

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

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

      _   EPA has statutory authority to permit continued sale, distribution and use of
  existingstocks of apesticide product which has been suspended or cancelled if doing so
  Rodenticide    8*6111 Whh ^ PUrPฐSeS ฐf the Fedqral ^s^cide,  Fungicide,  and
        The Agency has determined that such disposition by registrants of existing stocks
 for a suspended registration when a section 3(c)(2)(B) data request is outstanding would
 generally not be consistent with the Act's purposes. Accordingly, the Agency anticipates
 granting registrants permission to sell, distribute, or use existing stocks of suspended
 produces) only in exceptional circumstances. If you believe such disposition of existing
 stocks of your product(s) which may be suspended for failure to comply with this Notice
 should be permitted, you have the burden , of clearly demonstrating to EPA that granting
 such permission would be consistent with the Act. You must also explain why an
  existing stocks" provisions necessary, including a statement of the quantity of existing
 stocks and your estimate of the time required for their sale, distribution, and use  Unless
 you meet this burden the Agency will not consider any request pertaining to the continued
 sale, distribution, or use of your existing stocks after suspension.
 XT*-     ;          a voluntary cancellation of your product(s) as a response to this
 Notice and your product is in full compliance with all Agency requirements you will
 have, under most circumstances, one year from the date your 90 day response to this
 Notice is due, to sell, distribute, or use existing stocks:  Normally, the Agency will allow
 persons other than the registrant such as independent distributors,  retailers and end users
 to. sell, distribute or use such existing stocks until tSe stocks are exhausted  Any sale
 distribution^ or use of stocks  of voluntarily cancelled products containing an active
 ingredient(sKor which the Agency has particular risk concerns  will be determined on
 case-by-case basis.                                                       ;

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

       (1):    I will generate and submit data within the specified time frame (Developing  .
              Data)
       (2)     I have entered into an agreement with one or more registrants to develop data
   .          jointly (Cost Sharing)
       (3)     I have made offers to cost-share (Offers to Cost Share)

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


       The time frames in the Requirements Status and Registrant's Response Form are the time
frames that the Agency is allowing for the submission of completed study reports.  The noted
deadlines run  from the date of the receipt of this Notice by the registrant.  If the data" are not
                                         131,

-------
 submitted by the deadline, each registrant is subject to receipt of a Notice of Intent to Suspend
 the affected registration(s).

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

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

       Option 3. Offer to Share in the Cost of Data Development ~ This option only applies to
 acute toxicity and certain efficacy data as described  in option 2 above. If you have made an
 offer to pay  in an attempt to enter into an agreement or amend an existing agreement to meet the
 requirements of this Notice and have been unsuccessful, you may request EPA (by selecting this
 option) to exercise its discretion not to suspend your registration(s), although you do not comply
 with the data submission requirements of this Notice. EPA has determined that as a general
 policy, absent other relevant considerations, it will not suspend the registration of a product of a
 registrant who has in good faith sought and continues to seek to enter into a joint data
 development/cost sharing program, but the other registrant(s) developing the data has refused to
 accept your offer. To qualify for this option, you must submit documentation to the Agency
 proving that you have made an offer to another registrant (who has an obligation to submit data)
to share in the burden of developing that data.  You must .also submit to the Agency a completed
EPA Form 8570-32, Certification of Offer to Cost Share in the Development of Data,
Attachment 7. In addition, you must demonstrate that the other registrant to whom the offer was
                                          132

-------
 made has not accepted your offer to enter into a cost sharing agreement by including a copy of
 your offer, and proof of the other registrant's receipt of that offer (such as a certified mail
 receipt). Your .offer must, in addition to anything else, offer to share in the burden of producing
 the data upon terms to be agreed or failing agreement to-be bound by binding arbitration as
 provided by FDFRA section 3(c)(2)(B)(iii) and must not qualify this offer.  The other registrant
 must also inform EPA of its election of an option to, develop and submit the data required by
 this Notice by submitting a Data Call-In Response Form and a Requirements Status and
 Registrant's Response Form committing to develop and submit the data required by this Notice.

       In order for you to avoid suspension under this option, you may not withdraw your offer
 to share in the burdens of developing the data. In addition, the other registrant must fulfill its
 commitment to develop and submit the data as required by this Notice.  If the other registrant
 fails to develop the data or for some other reason is subject to suspension, your registration as
 well as that of the other registrant will normally be subject to initiation of suspension
 proceedings,  unless you commit to submit, and do submit the required data in the specified time
 frame. In such cases, the Agency generally will not grant a time extension for submitting the
 data; •                  .       '.','''."" '-•'. v •-    "    '.    •" •"'.•'.''•% •''•.';      • •   .

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

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

       To meet the requirements of the DCI Notice for submitting an existing study, all of the
following three criteria must be clearly met:              •
       a..
You must certify at the time that the existing study is submitted that the raw data
and specimens from the study are available for audit and review and you must
identify where they are available. This must be done in accordance with the
requirements of the Good Laboratory Practice (GLP) regulation, 40 CFRPart
160: As stated in 40 CFR 160.3(j) " 'raw data1 means any laboratory worksheets,
records, memoranda, notes, or exact copies thereof, that are the result of original
observations and activities of a study and are necessary for the reconstruction and
evaluation of the report of that study. In the event that exact transcripts of raw
data have been prepared (e.g., tapes which have been transcribed verbatim, dated,
and verified accurate by signature), the exact copy or exact transcript may be
substituted for the original source as raw data.  'Raw data' may include
photographs, microfilm or microfiche copies, computer printouts, magnetic
media, including dictated observations, and recorded data from automated
                                          133

               instruments." The term "specimens", according to 40 CFR 160.3(k), means "any
               material derived from a test system for examination or analysis."

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

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

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

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

       .Option 5, Upgrading a Study - If a study has been classified as partially acceptable and
 upgradeable, you may submit data to upgrade that study.  The Agency will review the data
 submitted and determine if the requirement is satisfied. If the Agency decides the requirement
 is not satisfied, you may still be required to submit new data normally without any time
 extension. Deficient,  but upgradeable studies will normally be classified as supplemental.
However, it is important to note that not all studies classified as supplemental are upgradeable
If you have questions  regarding the classification of a study or whether a study may be
upgraded, call or write the contact person listed in Attachment 1.  If you submit data to upgrade
an existing study you must satisfy or supply information to correct all deficiencies in the study
identified by EPA. You must provide a clearly articulated rationale of how the deficiencies
have been remedied or corrected and why the study should be rated as acceptable to EPA  Your
                                          134

-------
  submission must also specify the MRID number(s) of the study which you are attempting to
'  upgrade and must be in conformance with PR Notice 86-5.

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

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

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

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

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

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

 III-D REQUESTS FOR DATA WAIVERS

              If you request a waiver for produpt specific data because you  believe it is  -.
 inappropriate, you must attach a complete justification for the request, including technical
 reasons,, data and references to relevant EPA regulations,  guidelines or .policies.- (Note: any
 supplemental data must be submitted in the format required by PR Notice 86-5).  This will be
 the only opportunity to state the reasons or provide information in support of your request.  If
the Agency approves your waiver request, you will not be required to supply the data pursuant
to section 3(c)(2)(B) of FIFRA. If the Agency denies  your waiver request, you must choose an
 option for meeting the data requirements ,of this Notice within 30 days of the receipt  of the
Agency's decision. You must indicate'and submit the  option chosen on the Requirements Status
and Registrant's Response Form. Product specific data requirements for product chemistry,
acute toxicity and efficacy (where appropriate) are required for all products and the Agency
would grant a waiver only under extraordinary circumstances. You should also be aware that

submitting a waiver request will not automatically extend the due date for the study in question.
Waiver requests submitted without adequate supporting rationale will be denied and the original
due date will remain in force.

IV. CONSEQUENCES OF FAILURE TO COMPLY WITH THIS NOTICE

IV-A NOTICE OF INTENT TO SUSPEND                                        .       ,

 IV-B. BASIS FOR DETERMINATION THAT SUBMITTED STUDY IS
 UNACCEPTABLE                        ,

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

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

       2. EPA requirements regarding the submission of protocols, including the incorporation
       ofany.changes.requiredby the Agency following review.              .

       3. EPA requirements regarding the reporting of data, including the manner of reporting
       the completeness of results, and the adequacy of any required supporting (or raw) data,!
       including, but not limited to, requirements referenced or included in this. Notice or
       contained in PR 86-5.  All studies must be submitted in the form of a final report; a
       preliminary report will not be considered to fulfill the submission requirement.  '

IV-C EXISTING STOCKS OF SUSPENDED OR CANCELLED PRODUCTS

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

       The Agency has determined that such disposition by registrants of existing stocks for a
suspended registration when a section 3(c)(2)(B) data request is outstanding would generally not
be consistent with the Act's purposes. Accordingly, the Agency anticipates granting registrants
permission to sell, distribute, or use existing stocks of suspended product(s) only in exceptional
circumstances. If you believe such disposition of existing stocks of your product(s) which may
be suspended for failure to comply with this Notice should be permitted, you have the-burden of

-------
 clearly demonstrating to EPA that granting such permission would be consistent with the Act.
 You must also explain why an "existing stocks" provision is necessary, including a statement of
 the quantity of existing stocks and your estimate of the time, required for their sale, distribution,
 and use.  Unless you meet this burden the Agency will not consider any request pertaining to the
 continued sale, distribution, or use of your existing stocks after suspension.

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

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

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

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

 data pursuant to Section-3(c)(2)(B),of FIFRA. If the Agency denies my waiver '
 request, I must choose a method-of meeting,the data requirements of this Notice
 by the due date stated by this Notice. In this case, I must, within 30 days of my
 receipt of the Agency's written decision, submit  a revised "Requirements Status

         In an effort to reduce the time, resources and number of animals needed to fulfill the
  acute toxi.city data requirements for reregistration of products containing the active ingredient
  chlorpropham (Isopropyl Nr(3-chlorbphenyl) carbamate), the Agency has batched products
  that can be considered similar in terms of acute toxicity.  Factors considered in the sorting
  process include each product's active and inert ingredients (identity, percent composition and
  biological activity), type of formulation (e.g,, liquid, Avertable powder, .aerosol, granular, etc.),
  and labeling (e.g., signal word,, use classification, precautionary labeling, etc.).  Note that the'
  Agency is not describing batched products as "substantially similar" since some products
  within  a batch may not be considered chemically similar or have identical use patterns.

         Using available information, batching has been accomplished by the process described
  in the preceding paragraph. Notwithstanding the batching process, the Agency reserves the
  right to require, at any time, acute toxieity date for an individual product should the need
  arise/..;..  "       '         .     '  ,     •        .•.•.''..:  .'.,.,........-..,  ,  ."  ..-. .' •' >  ;..

         Registrants of products within a batch may choose to cooperatively generate, submit or
  cite a single battery of six acute toxicological studies to represent all the products within that
  batch.  It is the registrants' option to participate in the process with all other registrants, only
  some of the other registrants, or only their own products within a batchy or to general all the
  required acute toxicological studies for each of their own products. If a registrant chooses to
  generate the data for a batch, he/she must use one of the products within the batch as the test
  material.  If a registrant chooses to rely upon previously submitted acute toxieity data, he/she
  may do so if the data base is complete and valid by today's standards (see acceptance criteria
  attached), the formulation tested is considered by the Agency to be similar for acute toxieity,
  and the formulation has not been significantly, altered since submission and acceptance of the
  acute toxieity data. Regardless of .whether new data is generated or existing data is
,. referenced, registrants must clearly identify the test material by it's EPA Registration Number.
  If more than one confidential statement of formulation (CSF) exists for a product, the
  registrant must indicate the formulation actually tested by identifying the corresponding CSF.
                             : .•'•'•-.-  ',- •    •"•.,...ซ.  '  ;     '      •  '    '..  .' —
        In deciding how to meet the product specific data requirement, registrants must follow
  the directions given in the Data Call-in Notice and its attachments appended^ the RED. The
  DCI Notice contains two response forms that are to be completed and submitted to the
  Agency within 90 days of receipt. The first form, "Data Call-in Response," asks whether the
  registrant will meet the data requirements for each product. The second form, "Requirements
  Status^and Registrant's Response," lists the product specific data required for each product,
  including the standard six acute toxieity tests. A registrant who wishes to participate in a '
  batch must decide whether he/she will provide the data or depend on someone else to do so.
  If a registrant supplies,the data to, support a batch of products, he/she must select one of the
