CERTIFIED MAIL
Dear Registrant:

       I am pleased to announce that the Environmental Protection Agency has completed its
reregistration eligibility review and decisions on the pesticide chemical case Limonene which
includes the active ingredient limonene.

       The enclosed Reregistration Eligibility Decision (RED)  contains the Agency's
evaluation of the data base of this [these] chemical [s], its conclusions of the potential human
health and environmental risks of the current product uses, and its decisions and conditions
under which these uses and products will be eligible for reregistration.  The RED includes the
data and labeling requirements for products for reregistration.  It may also include
requirements for additional data (generic) on the active ingredient(s) to confirm the risk
assessments.

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

       If you have questions on the product specific data requirements or wish to meet with
the Agency, please contact the Special  Review and Reregistration Division representative
Franklin Gee at (703) 308-8008.  Address any questions on required generic data to the
Special Review and  Reregistration Division representative Emily Mitchell at (703) 308-8583.

                                                     Sincerely yours,
                                                     Louis P. True, Jr., Director

              SUMMARY OF INSTRUCTIONS FOR RESPONDING TO
              THE REREGISTRATION ELIGIBILITY DECISION (RED)

1.  DATA CALL-IN (PCI) OR "90-DAY RESPONSE" If generic data are required for
reregistration, a DCI letter will be enclosed describing such data.  If product specific data
are required, another DCI letter will be enclosed listing such requirements.  If both generic
and product specific data are required, a combined Generic and Product Specific letter will
be enclosed describing such data.  Complete the two response forms provided with each DCI
letter (or four forms for the combined) by following the instructions provided. You must
submit the response forms for each product and for each DCI within 90 days of the date
of this letter (RED issuance date); otherwise, your product may be suspended.

2.  TIME  EXTENSIONS AND DATA WAIVER REQUESTS No time extension requests
will be granted for the 90-day response. Time extension requests may be submitted only with
respect to actual data submissions. Requests for data waivers must be submitted  as part of the
90-day response. Requests for time extensions should be submitted in the 90-day response,
but certainly no later than the  8-month response date. All data waiver and time extension
requests must be accompanied by a full justification. All waivers and time extensions must be
granted by EPA in order to go into effect.

3.  APPLICATION FOR REREGISTRATION OR "8-MONTH RESPONSE" You must
submit the following items for each product within eight months of the date  of this letter
(RED issuance date).

      a.  Application for Reregistration (EPA Form 8570-1).  Use only an original
application form. Mark it "Application for Reregistration."  Send your Application for
Reregistration (along with the other forms listed in b-e below) to the address listed in item 5.

      b.  Five copies of draft labeling which complies with the RED and current regulations
and requirements.  Only make labeling changes which are required by the RED and current
regulations (40 CFR 156.10) and policies.  Submit any other amendments (such as formulation
changes, or labeling changes not related to reregistration) separately.  You may delete uses
which the RED says are ineligible for reregistration. For further labeling guidance,  refer to
the labeling section of the EPA publication " General Information on Applying for Registration
in  the U.S., Second Edition, August 1992" (available from the National Technical Information
Service, publication #PB92-221811;  telephone number 703-487-4650).

      c.  Generic or Product Specific Data. Submit all data in a format which complies
with PR Notice 86-5, and/or submit citations of data already submitted and give the EPA
identifier (MRID) numbers. Before citing these studies, you must make sure that they meet
the Agency's  acceptance criteria (attached to the DCI).

      d.  Two copies of the  Confidential Statement of Formula (CSF) for each basic and
each alternate formulation.  The labeling and CSF which you submit for each product must
comply with P.R. Notice 91-2 by declaring the active ingredient as the nominal
concentration.  You have two options for submitting a CSF:  (1) accept the standard certified
limits (see  40  CFR §158.175)  or (2)  provide certified limits that are supported by the analysis
of five batches.  If you choose the second option, you must submit or cite the data for the five
batches along  with a certification statement as described in 40 CFR §158.175(e).   A copy of
the CSF is enclosed; follow the instructions on its back.

-------
      e.  Certification With Respect to Data Compensation Requirements. Complete and
sign EPA form 8570-31 for each product.

EXECUTIVE SUMMARY

       The Agency has determined that the uses of limonene as currently registered will not
cause unreasonable risk to humans or the environment and these uses are eligible for
reregistration. The Agency is requiring additional confirmatory data for the 90-Day Dermal
Toxicity Study.

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

       Limonene is a naturally occurring chemical which is used in many food products,  for
its characteristic lemon-like flavor and odor. The Food and Drug Administration lists
limonene as a Generally Recognized as Safe (GRAS) food additive/flavoring and fragrance
additive (soap,perfume).

I.      INTRODUCTION

       In 1988, the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA) was
amended to accelerate the reregistration of products with active ingredients registered prior to
November 1, 1984. The amended Act provides a schedule for the reregistration process to be
completed in nine years. There are five phases to the reregistration process. The first four
phases of the process focus on identification of data requirements to support the reregistration
of an active ingredient and the generation and submission of data to fulfill the requirements.
The  fifth phase is a review by the U.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 limonene.  The document consists of six sections. Section I is the
introduction.  Section II  describes limonene,  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 limonene. Section
V  discusses the reregistration requirements for limonene.  Finally, Section VI is the
Appendices which support this Reregistration Eligibility Decision. Additional details
concerning the  Agency's review of applicable data are  available on request.

C.     Estimated Usage of Pesticide

       This section summarizes the best estimates available for the pesticide uses of
limonene.  These estimates are derived from a variety of published and proprietary
sources available to the Agency.  The data, reported on an aggregate and site (crop)
basis, reflect  annual fluctuations in use patterns as well as the variability in using data
from various  information sources.

       D.    Regulatory History
             Limonene was registered in the United States as an insecticide by the
       United States Department of Agriculture in 1958. Subsequently, limonene was
       first registered as an antimicrobial in 1971, and as a dog and cat repellent in
       1983.

             Limonene is an active ingredient in 15 currently registered products.
       These products are ready-to-use solutions, emulsifiable concentrates, granular,
       or impregnated material formulations.  The products are used for pet flea and
       tick control, as an insecticide spray, as an outdoor dog and cat repellent,
       as a fly repellent tablecloth, as an insect repellent for use on humans, and
       as a mosquito larvicide.

             On May 4,  1988, the Agency announced (53 FR 15989) that it no longer
       considered limonene to be an active ingredient if used in antimicrobial products.  For
       these products  the Agency considered limonene to function as as inert ingredient (i.e.
       odorants, perfumes).  See 40 CFR 153.139(a).

             In April 1994, limonene was granted an exemption from the requirement of a
       tolerance when it is an inert ingredient used as a solvent or fragrance in pesticide
       formulations (40 CFR 180.1001 (c), (e)).

             The Food and Drug Administration lists limonene as a Generally Recognized as
       Safe  (GRAS) (21 CFR 182.60) food additive/flavoring and fragrance additive (soap,
       perfume).
III.    SCIENCE ASSESSMENT

       A.    Physical Chemistry Assessment

             Limonene occurs naturally in fruits (especially citrus fruits, vegetables, meats, and
       spices).  As an additive it is found in a variety of foods and beverages.  It is listed by FDA as
       Generally Recognized As Safe (GRAS)  under Title 21 of the Code of Federal Regulations (21
       CFR 182.60).  Limonene is also used as an inert ingredient in pesticide formulations.

             Limonene ranges in color from clear to light yellow with a mild citrus-
       type odor. It is insoluble in water but soluble in mineral oils, fixed oils,
       alcohols and ether, and very slightly soluble in glycerin.

-------
B.     Human Health and Environmental Assessment

       Adequate toxicological and environmental effects data on limonene are available to support
reregistration eligibility.

       The Agency determined that limonene meets the criteria for a category of pesticide active
ingredients for which a reduced set of generic data requirements are appropriate for registration.
Products  in this category may be exempt from the generic data requirements for toxicology,
residue chemistry, human exposure, ecological effects, and environmental fate on the active
ingredient.  In considering limonene for reregistration eligibility, the Agency believes that it is
an active ingredient that meets the criterion for the following reasons:

1.   Limonene has been established  as  an inert and has been granted an exemption from the
requirement of a tolerance  when  used  as an inert in solvents or  fragrances in antimicrobial
pesticide formulations. Limonene, a naturally occurring chemical, is  found in high concentration
in  citrus fruits and spices and is generally regarded as safe by FDA.   It  is widely used as a
flavoring and/or frangrance additive  in foods, soaps, and perfumes.

2.  Adverse effects from exposure are sufficiently well known and documented in the literature.
Use of the substance for pesticidal purposes does not require additional data;  additional testing of
the pesticide active ingredient would not be expected to provide any additional information.

3.   The 90-day  dermal toxicity  study is required to support registration of an insect repellent
formulation to be directly applied to humans dermally, and is to be tested  using the formulation,
not technical limonene active ingredient alone.  The study will be  designed as a safety study.
Because the systemic toxicity is not anticipated, the requirement of a 90-day dermal toxicity study
is considered confirmatory.

4.   A  review of the available toxicity data indicates that adequate information is available to
characterize risks to  humans and animals.

5.  Limonene is not mutagenic or a developmental toxicant.  The primary toxicological concerns,
dermal irritation in  human and adverse effects in a small percentage of domestic animals, will
require precautionary statements on labels of products.   Systemic toxicity  in  humans is not
expected to occur from pesticide uses since dermal irritation, which occurs at high  doses leads to
self-discontinuation of product use.

       An assessment of the data used in determining the reregistration eligibility of limonene is
detailed below.

-------
1.      Toxicology Assessment

       Adequate animal toxicological data on limonene are available and will support
reregistration eligibility.

       Toxicology data on limonene reviewed here includes a 1992 National Toxicology
Program (NTP) 2-year cancer bioassay including shorter-term oral toxicity tests and a
comprehensive literature  review,  a developmental toxicity study in  rat, a 2-week
preliminary study conducted for  a 90-day dermal toxicity study in rat and the U.S. EPA
Risk  Assessment  Forum document  entitled  "Alpha2u-Globulin:    Association with
Chemically Induced Renal Toxicity and Neoplasia in the Male Rat".

       a.     Acute Toxicity

             The oral toxicity of limonene is relatively low.  An  oral lethal dose for
       humans has been estimated at 1 oz.  - 1 pint.  Limonene has been  administered
       therapeutically to humans  at doses of 20 g to dissolve gallstones. Systemic toxicity
       from dermal exposure is anticipated to be lower than  oral toxicity because dermal
       penetration is expected to  be less than 100% and since  local dermal irritation  would
       occur at high exposure levels, causing discontinuation of exposure.
       b.     Subchronic Toxicity

             In the NTP study, toxicity of limonene administered by gavage in corn oil
       was assessed  in CD rats and in B6C3F1 mice in 16-day,  13-week and 2-year
       studies.  In the 16-day study, no effects were observed in males at or below 825
       mg/kg/day or  in females at or below 1,650 mg/kg/day.  Decreased body weights
       were observed in males at 1,650 mg/kg/day and in females at 3,300 mg/kg/day.
       Deaths occurred at 3,300 and 6,600 mg/kg/day among both males and females.

             In the 13-week study, no effects were observed in females at or below 600
       mg/kg/day.  At 1,200 and 2,400 mg/kg/day clinical signs  (lethargy, salivation)
       were observed in males and females.  Decreased body weight was observed in
       males at 1,200 mg/kg/day and females at 2,400 mg/kg/day. Lacrimation, rough
       coat and lethargy were noted at 1,200 mg/kg/day. Nephropathy related to alpha2u-
       globin accumulation was observed in male rats at all doses (150 mg/kg/day above).
       Mortality was increased in males and females at 2,400 mg/kg/day  (highest dose
       tested).

-------
c.      Chronic toxicity

       In the 2-year study, male rats were given 75 or 150 mg/kg/day and females
300 or 600 mg/kg/day limonene.  At 150 mg/kg/day males had slightly decreased
body weight but at both doses developed alpha2u-globulin nephrotoxicity and renal
adenoma/adenocarcinoma.  Females showed no effects at 300 mg/kg/day but at
600 mg/kg/day had slightly decreased body weight and increased mortality.

       Mice given limonene at the same doses in the 16-day and 13-week studies
also showed limited evidence of toxicity at high doses,  although some body weight
decrease in males was  observed at all doses.  Mice were given 250  or  500
mg/kg/day  (males) or 500 or  1000 mg/kg/day (females) in the 2-year  study.
Females at 1000 mg/kg/day had decreased body weight.  No  treatment-related
nephropathy or renal adenomas/carcinomas were observed in either sex in the 2-
year study.

d.     Mutagenicity and Carcinogenicity

       Limonene  is  not  mutagenic  in  numerous  assays.    Renal  adeno-
mas/carcinomas in male  rats administered limonene  for 2 years  (NTP study) are
considered to be related to alpha2u-globulin-induced nephropathy and therefore are
not considered relevant to human  risk assessment  (Risk Assessment  Forum
document on alpha2u-globulin nephropathy).

e.      Developmental Toxicity

       Limonene is not a developmental toxicant.  Delayed ossification in bone
development may be observed at high doses that also cause maternal toxicity.
Several developmental toxicity studies were cited in the literature review of the
NTP  study.  No  developmental  effects were  observed in rabbits administered
limonene up to 1,000 mg/kg;  6/21 maternal animals died and decreased body
weight was observed.  At 250 mg/kg no maternal or developmental toxicity  was
observed.    Pregnant rats given 2,869 mg/kg limonene during days  9-15 of
gestation showed decreased body weight gain.  Delayed ossification was  seen in
fetuses at this dose, presumably secondary to maternal effects.   A study in mice
(2,363 mg/kg during days 7-12 of gestation) also showed decreased maternal body
weight gain with increased incidence of abnormal bone formation in fetuses.
However, the dose administered in these two studies far exceeded limit doses.

       In the rat developmental toxicity study submitted to the Agency in 1992,
a  NOEL of 250  mg/kg/day  for  maternal  and developmental toxicity  was
determined.  Small decrements in maternal body weight  gain were observed at 500
and  1000  mg/kg/day and excess  salivation at 1000 mg/kg/day.   Slight but
statistically significant and dose-dependent increases in the number of liters and

-------
       fetuses with 14 ribs instead of 13 were observed at 500 and 1000  mg/kg/day.
       These  effects  are  considered  variations  in  skeletal  formation,  were  not
       accompanied by other effects, are secondary to maternal toxicity  and do not
       represent a concern for developmental toxicity of limonene.

       f.      Other Toxic Endpoints

              Limonene is a known dermal irritant when applied at high concentrations
       and may cause dermal sensitization.  The 2-week preliminary study for the rat 90-
       day dermal toxicity study submitted as 6 (a) (2) data showed that dermally-applied
       technical limonene at 500, 1,000 or 1,500 mg/kg/day produced excessive dermal
       irritation, usually after 1-3 days of application. No overt treatment-related systemic
       toxicity or clinical signs were observed.

              The 90-day dermal safety study on the formulation of the newly registered
       product (Registration Number 045987-G) is required because the product use may
       result in prolonged human dermal exposure through repeated skin applications.
       The  safety  study on the  formulated  product  is also needed because of the
       combination of ingredients in the formulation.  This will ensure the combination
       in the formulation does not cause unexpected effects.

              Another report cited in that submission indicated that doses  of pine  oil
       blend (a mix of terpenes including limonene) up to 226 mg/kg/day did not produce
       dermal irritation or systemic toxicity in rats after a 90-day exposure.

2.     Exposure Assessment

       a.      Occupational and Residential

              The primary toxicologic concerns for humans are dermal irritation and/or
       sensitization from dermal exposure at high concentrations.  Systemic toxicity is not
       expected to occur from pesticide uses since dermal irritation, which occurs at high
       doses, results in self-discontinuation of product use.

              The  primary  toxicologic  concerns for domestic  animals  are adverse
       reactions in a small percentage of animals,  cats in particular, exposed to limonene
       in flea and tick spray,  shampoo or dip products.

              An  animal safety  study in cats  on a flea dip indicated that a small
       percentage of cats may develop transient symptoms when treated according to label
       instructions and that  kittens/young cats  are more sensitive.   Labels contain
       Precautionary Statements indicating the potential for  dermal irritation, sensitivity
       of some animals to treatment, prohibiting use on weanling kittens and cautioning
       against use of undiluted product.


                                 10

-------
                    Symptoms of limonene toxicity may include hypothermia, tremors, ataxia
             and excess salivation.  Agitation and vocalization may also occur.  Irritation of the
             skin, particularly around the scrotum, has been reported and ocular irritation may
             occur if eyes are accidentally exposed.
       3.     Risk Assessment

             a.     Occupational and Residential

                    Human exposure  may  occur during application of pet flea products,
             application of pet flea products, application of animal repellent granules or insect
             spray, or  use  of impregnated tablecloths.  The tablecloth product containing
             limonene to repel insects was exempted from tolerances.  Toxicologic concerns for
             humans  from  exposure to limonene are dermal  irritation  and sensitization.
             Systemic toxicity is not anticipated to  occur  at doses below  the threshold for
             dermal irritation. Exposure to limonene would be discontinued if dermal irritation
             occurred  and is therefore self-limiting.  Ocular  irritation may also occur if
             products are accidentally placed in the eye and not washed away.

                    Limonene is an active ingredient in several registered shampoo, dip and
             spray products applied dermally to domestic animals to control fleas and ticks.
             Most sprays and shampoos contain 5% limonene; dip concentrates (32-78%) are
             diluted prior to use to  less than 1%  limonene.  Adverse reactions in domestic
             animals, particularly cats from exposure to limonene have been reported following
             exposure to flea control products.

                    Additional precautionary statements on label are required to reduce adverse
             effects.

C.     Environmental Assessment

       1.     Environmental Fate

             a.     Environmental Chemistry, Fate and Transport

                    The Agency is  relying on data available in the literature to  assess the
             environmental fate  of limonene for its current uses.

             b.     Environmental Fate Assessment

                     Limonene  [l-methyl-4-(l-methylethenyl)cyclohexene]  is classified  as a
             terpene.  It contains  a carbon skeleton made up of isoprene units joined in a head-
             to-tail way. The chemical is insoluble in water.  Because limonene does not  have

                                       11

-------
       functional groups for hydrolysis, and its cyclohexene ring and ethylene group are
       known to be resistent to hydrolysis,  the compound is expected to be stable in
       water.

2.     Ecological Effects

       a.      Ecological Effects Data

              (1)    Terrestrial Data

                     Terrestrial Animal Data

                    In order to establish the toxicity of limonene to birds,  the following
              tests would ordinarily be required using the technical grade material: one
              avian single-dose oral (LD50) study on one species (preferably mallard duck
              or bobwhite quail); two subacute dietary studies (LC50) tests on one species
              of  waterfowl (preferably the mallard duck) and one upland game-bird
              species (preferably the bobwhite quail). However, because the present use
              patterns of limonene were deemed low  volume, the requirement for a
              dietary test with  a waterfowl species has been waived.

                    The data submitted for limonene includes studies on both technical
              and formulated  product.   Because  the  first  products  registered were
              basically indoor-use applications for controlling ticks and fleas on dogs and
              cats, acute oral testing was not required for technical limonene.  When the
              first of two products with outdoor uses was proposed for registration, it
              was concluded  that  any additional  testing should be  done  using the
              formulated product, which contains other active ingredients and inerts that
              may be more toxic than limonene.

(2)     Aquatic Data

       Freshwater Fish Toxicity

       In order to establish the toxicity of a  pesticide to freshwater
fish, the minimum data required on the technical grade of the active
ingredient are two  freshwater  fish toxicity studies.   One study
should use a coldwater species  (preferably  rainbow trout) and the
other a warmwater species (preferably bluegill sunfish).   For the
same reasons noted for  the  terrestrial tests,  some  testing was
conducted on the formulated product rather than the technical.

       Freshwater Invertebrate Toxicity

       In order to establish the toxicity of a pesticide to freshwater
aquatic invertebrates, the minimum data required on the technical
grade of the active ingredient  is  one acute toxicity study. The
preferred test species is first instar Daphnia magna or early instar
amphipods, stoneflies, or mayflies.

b.     Ecological Effects Risk Assessment

       Risk to Terrestrial Animals

              Avian Acute Oral and Subacute Dietary Effects

              Limonene has not been quantitatively assessed. However,
       based on the lack of toxicity of limonene to birds,  little risk is
       anticipated.

              Potential risk  to birds  might occur from  ingestion  of
       granules  spread on lawns, driveways, and sidewalks;  or  from
       consumption of contaminated insects around sprayed manure heaps,
       compost  piles, garbage pails, and dumpsters.

              "The Agency is unable to calculate an acute risk quotinent
       for birds,  because  toxicity test  effect levels are unknown.   The
       acceptable avian acute oral study demonstrated an LD50 greater than
       2,000 mg/kg for the formulated product.  The  Agency's Guidelines
       for Avian Acute Oral testing specify that a study may demonstrate
       that  the  actual LD50 is greater than 2,000 mg/kg, in lieu  of
       demonstrating an actual LD50. Because the submitted study tested
       up to the  maximum 2,000 mg/kg level and no indications of toxicity
       were noted, the Agency has determined it is reasonable to assume
       that the regulatory levels of concern for  acute  effects will not  be
       exceeded."
                       16

-------
       The risk to birds from possible consumption of contaminated
insects around the outdoor sites where insects are sprayed cannot be
quantitatively assessed.  Directions for use on the  label for EPA
Registration No.  45987-2 include spraying "to wet"  crawling ants,
roaches, and flying  insects;  thoroughly spraying  ant  trails  on
sidewalks,  paths, and buildings, repeating the treatment a second
time if ants reappear a few days later; and liberally spraying and
thoroughly wetting  manure heaps, compost  piles, and insect-
attracting garbage pails and dumpsters. Insects (e.g.,  flies, beetles,
larva)  contaminated by such  spraying might be consumed by a
variety of birds.   However,  based on  the lack  of  toxicity  of
limonene to birds, little risk is anticipated.

       Mammalian Acute Effects

       The acute oral LD50 value  for the rat is greater than 5000
mg/kg, which classifies it as practically nontoxic.  Because granular
limonene is registered as a mammalian repellent and is practically
nontoxic, it is not anticipated that  granules would be consumed in
sufficient quantities to be a risk to  mammals.
Risk to Aquatic Animals

        Mosquito Larvicide Use

        The LOG for freshwater invertebrates was exceeded (risk
quotient =  1.5) for the mosquito  larvicide use. However, the end-
use product is expected to dissipate rapidly, by break up of the oily
film.  Thus, due to the likely short duration of the effect, there is
not a major ecological concern.

Direct Application to Water

       The mosquito larvicide product is applied directly to water
where breeding mosquitos are likely to be. Potential risk to aquatic
organisms is estimated by the EEC/LC50 (or EC50).  This is the risk
quotient (RQ).  The Level of Concern (LOG)  for this endpoint is a
risk quotient greater than or equal to 0.5 for nonendangered species
and 0.05 for endangered species.

       The EEC is calculated below.  It is based on the maximum
direct application to water, which is 5 gallons per acre. For this
                17

use a six inch water body scenario is used since mosquito breeding
areas are likely to be in shallow water.

EEC = 34.15 Ibsx734ppb
(where34.15 = max. appL rate in Ibsproduct/acre which equals 5 gal/acre x 6.83 Ibs/gal and 734ppb
= EEC for a direct application ofl Ib. to 6 Inches of water) = 25ppm)

       The aquatic organisms of concern in this case, based on the
toxicity  of the  formulated product  to  daphnids,  are aquatic
invertebrates with a formulated product EC50 of 17-20 ppm.  The
risk quotient for these organisms is 25/17 =  1.5, which exceeds the
level of concern.  However, due to the nature of the product and
the  likely  short  duration  of the  effect,  there  is  not a major
ecological concern.

       Other (Non-larvicide) Uses

       Minimal risks to nonendangered and  endangered aquatic
species are expected from  runoff into ponded waters 6-feet  deep
from applications of the granular product.

Ground Application

   Runoff of limonene into water bodies could present a potential
risk to aquatic  organisms.   Runoff  of  pesticide from ground
applications was estimated by multiplying the maximum application
rate (Ibs ai/acre) by the percent runoff (based on solubility) from a
10-acre drainage basin into a 1-acre water body.  Because solubility
data are unavailable for  limonene the maximum pesticide runoff,
which  is  5%, was assumed.  Based on  these assumptions the
maximum aquatic concentration of limonene is 0.5 ppm for a 6-ft.

IV.    RISK MANAGEMENT AND REREGISTRATION DECISION

       A.     Determination of Eligibility

              Section 4(g)(2)(A) of FIFRA calls for the Agency to determine, after submission
       of relevant data concerning an active ingredient, whether products containing the active
       ingredients are eligible for  reregistration.  The Agency has previously identified and
       required the submission of the generic (i.e. active ingredient specific)  data required to
       support reregistration of products containing limonene active ingredients. The Agency has
       completed its review of these generic data, and has determined that the data are sufficient
       to support reregistration of all products containing limonene.  Appendix B identifies the
       generic data requirements that the Agency  reviewed as part of its determination  of
       reregistration eligibility of limonene, and lists the submitted studies that the Agency found
       acceptable.

              The data identified in Appendix B were  sufficient to allow the Agency to assess the
       registered uses of limonene and to determine that limonene can  be used without resulting
       in unreasonable adverse effects to humans and the environment.  The Agency therefore
       finds  that all  products containing limonene  as the active  ingredients are eligible for
       reregistration.  The reregistration of particular products is addressed in Section V of this
       document.

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

              1.      Eligibility Decision

                     Based  on the reviews of the  generic data  for  the active ingredients
              limonene, the Agency has sufficient information on the health effects of limonene
              and on its potential for  causing adverse effects in fish and wildlife  and the
              environment. Therefore, the Agency concludes  that products containing limonene
              for all uses are eligible for reregistration.

                     The Agency has determined that limonene products, labeled and used as
              specified in this Reregistration Eligibility Decision, will not pose unreasonable
              risks or adverse effects to humans or the environment.

       2.     Eligible and Ineligible Uses

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

B.     Regulatory Position

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

C.     Tolerance Reassessment

       In  April  1994, limonene was granted an exemption from the requirement of a
tolerance  when  it is  an inert ingredient  used  as  a solvent or fragrance in pesticide
formulations [cite Federal Register citation; i.e., 40 CFR §180.1001 (c), (e)].
                                    21

-------
V.     ACTIONS REQUIRED BY REGISTRANTS

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

       A.    Manufacturing-Use Products

             1.     Additional Generic Data Requirements

                    The  generic data base supporting the reregistration of limonene for the
             above eligible uses has been reviewed and determined to be substantially complete.
             However, additional confirmatory data is needed for the 90-Day
             Dermal Toxicity study to fulfill the data requirements.

             2.     Labeling Requirements for Manufacturing-Use Products

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

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

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

                    (a)  "This product may be used to formulate products for
                          specific use(s) not listed on the MP label if the
                          formulator, user group, or grower has complied with
                          U.S. EPA submission requirements regarding the support
                          of such use(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)."
                                          22

-------
B.     End-Use Products

       1.     Additional Product-Specific Data Requirements

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

             Registrants must review previous data submissions to ensure that they meet
       current EPA acceptance criteria (Appendix F; Attachment E) and if not, commit
       to conduct new studies. If a registrant believes that previously  submitted data meet
       current testing standards,  then study MRID numbers should be cited according to
       the instructions in the Requirement Status and Registrants Response Form provided
       for each product.

       2.     Labeling Requirements for End-Use Products

       Worker Protection Standard

             To the Agency's knowledge, at this time all registered uses of limonene are
       outside the  scope of the  Worker Protection Standard for Agricultural Pesticides
       (WPS). The Agency will not establish entry restrictions at this time for limonene
       end-use products.

             The  labeling language for the end-use products:

             (a) End-Use Products (except the mosquito larvicide  use)
                    Do not apply directly to water, or to areas where surface
                    water is present or to intertidal areas below the mean high-
                    water mark.  Do not contaminate water when  disposing of
                    equipment washwater or rinsate.

             (b) End-Use Products (mosquito larvicide use)
                    Do not contaminate water when disposing of equipment
                    washwater or rinsate.  Consult with your State Agency
                    in charge of fish and game before applying to  public
                    waters to determine if a permit is needed.

             The  labels and labeling of all products must comply  with EPA's current
       regulations and requirements as specified in 40 CFR §156.10and other applicable
       notices.
                                    23

-------
       3.      Additional Label Requirements

          Although the toxicology of limonene has been adequately characterized
       and toxicity  is generally relatively low, adverse effects may occasionally
       occur in pets exposed to limonene flea/tick dips, shampoos and sprays.
       Labels contain precautionary statements regarding sensitivity among some
       individual animals, dermal/ocular irritation, use on kittens or nursing
       mothers and warning against using undiluted product.  Although the labels
       provide appropriate information, the Agency requires the  following changes
       to strengthen the language and further reduce risk of adverse effects:

              - Add:  Applicators of flea and tick dip (concentrates), spray or
                shampoo products  are to use protective  gloves  to reduce the risk of
               dermal irritation or dermal sensitization.

              - Add:   Flea dip concentrates may harm animals  when used at greater
               strength than specified on the label.

              - Change the age for product use on kittens/puppies to several months or
               a year.

              - Change the statement:  "Use with care on nursing animals" to "Do not
               use  on nursing animals or any animal which is in poor health".

              - Provide a list of symptoms, which may occur when animals are sensitive
               to the product, to the precautionary statement "individual animals may
               may be more sensitive to the product".

       4.      Existing Stocks

       Registrants may generally distribute and sell products bearing old labels/labeling
for 26 months from the date of the issuance of this Reregistration Eligibility Decision
(RED). Persons other than the registrant may generally distribute or sell such products for
50 months from the date  of the issuance of this RED. However, existing stocks time
frames will be established case-by-case, depending on the number of products involved,
the number of label changes, and other factors. Refer to  "Existing Stocks of Pesticide
Products;  Statement of Policy"; Federal Register,  Volume 56, No. 123, June 26, 1991.

       The  Agency has determined that registrants may  distribute and sell limonene
products bearing old labels/labeling for  26 months from the date of issuance  of this RED.
Persons other than the registrant may distribute or sell such products for 50  months from
the date of the issuance of this RED.  Registrants and persons other than registrants remain
obligated  to meet  pre-existing  Agency-imposed  label  changes  and existing  stocks
requirements applicable to products  they sell or distribute.

                               GUIDE TO APPENDIX B

Appendix B contains listings of data requirements which support the reregistration for active
ingredients within the case Limonene covered by this Reregistration Eligibility Decision
Document. It contains generic data requirements that apply to Limonene in all products,
including data requirements for which a "typical formulation" is the test substance.

       The data table is organized in the following format:

       1.  Data Requirement (Column 1).  The data requirements  are listed in the order in
which they appear in 40 CFR Part 158. the reference numbers accompanying each test refer
to the test protocols set in the Pesticide Assessment Guidelines, which are available from the
National Technical Information Service, 5285 Port Royal Road, Springfield,  VA 22161 (703)
487-4650.

       2.  Use Pattern  (Column 2).  This  column indicates the use patterns for which the data
requirements apply.  The  following letter  designations are used for the given  use patterns:

                           A      Terrestrial food
                           B      Terrestrial feed
                           C      Terrestrial non-food
                           D      Aquatic food
                           E      Aquatic non-food outdoor
                           F      Aquatic non-food industrial
                           G      Aquatic non-food residential
                           H      Greenhouse food
                           I       Greenhouse non-food
                           J       Forestry
                           K      Residential
                           L      Indoor food
                           M     Indoor non-food
                           N      Indoor medical
                           0      Indoor residential

       3.  Bibliographic citation (Column 3).  If the Agency has acceptable data in its files,
this column lists the identifying number of each study.  This normally is the Master Record
Identification (MRID) number, but may be a "GS" number if no MRID number has been
assigned.  Refer to the  Bibliography appendix for a complete citation of the study.

                               GUIDE TO APPENDIX C

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

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

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

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

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

       b.     Document date.  The date of the study is taken directly from the document.
             When the date is followed by a question mark, the bibliographer has deduced
             the date from the evidence contained in the document.  When the date appears


                                           53

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

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

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

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

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

       (3)    Submitter.  The third  element is the submitter.  When authorship is
             defaulted to the submitter, this element is omitted.

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

                                  July 29, 1986

                                                            OFFICE OF
                                PR NOTICE 86-5         PREVENTION, PESTICIDES
                                                      AND TOXIC SUBSTANCES


          NOTICE TO PRODUCERS,  FORMULATORS,  DISTRIBUTORS
                         AND REGISTRANTS

Attention:      Pers9ns responsible for Federal  registration of
                pesticides.

Subject:        Standard format for data submitted under the
                Federal Insecticide,  Fungicide,  and Rodenticide
                Act  (FIFRA)  and certain provisions of  the Federal
                Food, Drug,  and Cosmetic Act  (FFDCA).

I.    Purpose

     To require data to be  submitted to the  Environmental
Protection Agency  (EPA) in  a standard  format. This Notice  also
provides additional guidance about,  and illustrations of,  the
required formats.

II.  Applicability

     This PR Notice applies to all data that are submitted to EPA
to satisfy data requirements for granting or maintaining
pesticide registrations, experimental  use permits, tolerances,
and related approvals under certain  provisions  of FIFRA and
FFDCA.  These data are defined in FIFRA §10(d)(1).  This Notice
does not apply  to commercial, financial, or production
information, which are, and must continue to be, submitted
differently under separate  cover.

Ill.  Effective  Date

     This notice is effective on November 1, 1986. Data formatted
according to this notice may be submitted prior to the  effective
date.  As of the effective  date, submitted data packages that do
not conform to  these requirements may  be returned to  the
submitter for necessary revision.

IV.  Background

     On September 26, 1984, EPA published proposed regulations  in
the Federal Register  (49 FR 37956) which include Requirements for
Data Submission (40 CFR §158.32), and  Procedures for  Claims of
Confidentiality of Data (40 CFR §158.33). These regulations
specify the format for data submitted  to EPA under Section 3 of
FIFRA and Sections 408 and  409 of FFDCA, and procedures which
must be followed to make and substantiate claims of confiden-
tiality.  No entitlements to data confidentiality are changed,
either by the proposed regulation or by this notice.

     OPP is making these requirements  mandatory through this
Notice to gain  resource-saving benefits from their use  before the



                                93

-------
entire proposed regulation becomes final.  Adequate lead time is
being provided for submitters to comply with the new
requirements.

V.   Relationship of this Notice to Other OPP Policy and Guidance

     While this Notice contains requirements for organizing and
formatting submittals of supporting data,  it does not address the
substance of test reports themselves.  "Data reporting" guidance
is now under development in OPP, and will specify how the study
objectives, protocol, observations, findings, and conclusions are
organized and presented within the study report. The data
reporting guidance will be C9mpatible with submittal format
requirements described in this Notice.

     OPP has also promulgated a policy (PR Notice 86-4 dated
April 15, 1986) that provides for early screening of certain
applications for registration under FIFRA §3.  The objective of
the screen is to avoid the additional C9sts and prolonged delays
associated with handling significantly incomplete application
packages.  As of the effective date of this Notice,  the screen
will include in its criteria for acceptance of applicati9n
packages the data formatting requirements described herein.

     OPP has also established a public docket which imposes
deadlines for inserting int9 the docket documents submitted in
connection with Special Reviews and Registration Standards  (see
40 CFR §154.15 and §155.32).  To meet these deadlines, OPP is
requiring an additional copy of any data submitted to the docket.
Please refer to Page 10 for more information about this
requirement.

     For several years, OPP has required that each application
for registration or other action include a list 9f all applicable
data requirements and an indication of how each is satisfied--the
statement of the method of support f9r the application.
Typically, many requirements are satisfied by reference to data
previously submitted--either by the applicant or by another
party.  That requirement is not altered by this notice, which
applies only to data submitted with an application.

VI.   Format Requirements

     A more detailed discussion of these format requirements
foll9ws the index on the next page, and samples of some of the
requirements are attached.  Except for the language 9f the two
alternative forms of the Statement of Data Confidentiality Claims
(shown in Attachment 3) which cannot be altered, these samples
are illustrative.  As long as the required information is
included and clearly identifiable, the form of the samples may be
altered to reflect the submitter's preference.

A.   Organization of Submittal Package

     A "submittal package" consists of all studies submitted at
the same time f9r review in support of a single regulatory
action, along with a transmittal document and other related
administrative material  (e.g. the method of support statement,
EPA Forms 8570-1, 8570-4, 8570-20, etc.) as appropriate.

     Data submitters must organize each submittal package as
described in this Notice.  The transmittal and any other admin-
istrative material must be grouped together in the first physical
volume.  Each study included in the submittal package must then
be bound separately.

     Submitters sometimes provide additional materials that are
intended to clarify, emphasize, or otherwise comment to help
Product Managers and reviewers better understand the submittal.

        If such materials relate to one study, they should be
     included as an appendix to that study.

     - If such materials relate to more than one study  (as for
     example a summary of all studies in a discipline) or to the
     submittal in general, they must be included in the submittal
     package as a separate study  (with title page and statement
     of confidentiality claims).

B.   Transmittal Document

     The first item in each submittal package must be a trans-
mittal document.  This document identifies the submitter or all
joint submitters; the regulatory action in support of which the
package is being submitted--!.e., a registration application,
petition, experimental use permit (EUPT, §3(c)(2)(B) data
call-in,  §6(a)(2) submittal, 9r a special review; the transmittal
date; and a list of all individual studies included in the
 gackage in the order of their appearance, showing (usually by
 uideline reference number)  the data requirement(s)  addressed by
each one.  The EPA-assigned number for the regulatory action
(e.g. the registration, EUP, or tolerance petition number) should
be included in the transmittal document as well, if it is known
to the submitter.  See Attachment 1 for an example of an
acceptable transmittal document.

     The list of included studies in the transmittal of a data
submittal package supporting a registration application should be
subdivided by discipline, reflecting the order in which data
requirements appear in 40 CFR 158.

     The list of included studies in the transmittal of a data
submittal package supporting a petition for tolerance or an


                                95

-------
application for an EUP should be subdivided into sections A, B,
C,....  of the petition or application,  as defined in 40 CFR 180.7
and 158.125, (petitions)  or Pesticide Assessment Guidelines,
Subdivision I (EUPs)  as appropriate.

     When a submittal package supports a tolerance petiti9n and
an application for a registration or an EUP, list the petition
studies first,  then the balance of the studies.  Within these two
groups of studies follow the instructions above.

C.   Individual Studies

     A study is the report of a single scientific investigation,
including all supporting analyses required for logical complete-
ness.   A study should be identifiable and distinguishable by a
C9nventional bibliographic citation including author, date, and
title.   Studies generally correspond in scope to a single Guide-
line requirement for supporting data, with 39016 exceptions dis-
cussed in section C.I.  Each study included in a submittal
 Eackage must be bound as a separate entity.  (See comments on
 inding studies on page 9.)

     Each study must be consecutively paginated, beginning from
the title page as page 1.  The total number of pages in the com-
plete study must be shown on the study title page.  In addition
(to ensure that inadvertently separated pages can be reassociated
with the proper study during handling or review) use either of
the following:

     - Include the total number of pages in the complete study on
     each page (i.e., 1 of 250, 2 of 250,  ...250 of 250).

     - Include a company name or mark and study number on each
     page of the study, e g ,  Company Name-1986-23.    Never reuse
     a study number for marking the pages of subsequent studies.
     When a single study is extremely long, binding it in mul-
tiple V9lumes is permissible so long as the entire study is pag-
inated in a single series,  and each volume is plainly identified
by the study title and its position in the multi-volume sequence.

C.1  Special Considerations for Identifying Studies

     Some studies raise special problems in study identification,
because they address Guidelines of broader than normal scope or
for other reasons.

     a. Safety Studies.  Several Guidelines require testing for
safety in more than one species. In these cases each species
tested should be reported as a separate study,  and bound
separately.

     Extensive supplemental reports of pathology reviews, feed
analyses, historical C9ntrol data, and the like are often assoc-
iated with safety studies.   Whenever possible these should be
submitted with primary reports of the study, and bound with the
primary study as appendices.  When such supplemental reports are
submitted independently of the primary report,  take care to fully
identify the primary report to which they pertain.

     Batteries of acute toxicity tests, performed on the same end
use product and covered by a single title page, may be bound
together and reported as a single study.

     b. Product Chemistry Studies.   All product chemistry data
within a submittal package submitted in support of an end-use
product produced from registered manufacturing-use products
should be bound as a single study under a single title page.

     Product chemistry data submitted in support of a technical
product, other manufacturing-use product, an experimental use
permit, an import tolerance petition, or an end-use product


                                96

-------
produced from unregistered source ingredients, should be bound as
a single study for each Guideline series  (61, 62, and 63) for
C9nventional pesticides, or for the equivalent subject range for
biorational pesticides.  The first of the three studies in a
complete product chemistry submittal for a biochemical pesticide
would cover Guidelines 151-10,  151-11,  and 151-12; the second
would cover Guidelines 151-13,  151-15,  and 151-16; the third
would cover Guideline 151-17. The first study for a microbial
pesticide would cover Guidelines 151-20, 151-21,  and 151-22; the
second W9uld cover Guidelines 151-23 and 151-25;  the third would
cover Guideline 151-26.

     Note particularly that product chemistry studies are likely
to contain Confidential Business Information as defined in FIFRA
§10(d)(1)(A), (B) ,  or  (C),  and if so must be handled as described
in section D.3.  of this notice.

     c.   Residue Chemistry Studies.   Guidelines 171-4, 153-3,
and 153-4 are extremely broad in scope; studies addressing
residue chemistry requirements must thus be defined at a level
below that of the Guideline code.  The general principle,
h9wever, of limiting a study to the report of a single inves-
tigation still applies fully.  Data should be treated as a single
study and bound separately for each analytical method, each
report of the nature of the residue in a single crop or animal
species, and for each report of the magnitude of residues
resulting from treatment of a single crop or from processing a
single crop.  When more than one commodity is derived from a
single crop  (such as beet tops and beet roots) residue data on
all such C9mmodities should be reported as a single study.  When
multiple field trials are associated with a single crop, all such
trials should be reported as a single study.
D.
Organization of Each Study Volume
     Each complete study must include all applicable elements in
the list below, in the order indicated.  (Also see Page 17.)
Several of these elements are further explained in the following

-------
D.I. Title Page

     A title page is always required for each submitted study,
published or unpublished.  The title page must always be freely
releasable to requestors; DO NOT INCLUDE CBI ON THE TITLE PAGE.
An example of an acceptable title page is on page 12 of this
notice.  The following information must appear on the title page:

a.   Study title.  The study title should be as descriptive as
possible It must clearly identify the substance(s) tested and
correspond to the name of the data requirement as it appears in
the Guidelines.

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

c.   Author(s).  Cite only individuals with primary intellectual
responsibility for the C9ntent 9f the study.  Identify them
plainly as authors,  to distinguish them from the performing
laboratory, study sponsor, or other names that may also appear on
the title page.

d.   Study Date.  The title page must include a single date for
the study.  If parts of the study were performed at different
times, use only the date of the latest element in the study.

e.   Performing Laboratory IdentificatJ9n.   If the study reports
work done by one or more laboratories,Include on the title page
the name and address of the performing laboratory or
laboratories, and the laboratory's internal project number(s) for
the work.  Clearly distinguish the laboratory's project
identifier from any other reference numbers provided by the study
sponsor or submitter.

f.   Supplemental Submissions.  If the study is a commentary on
or supplement to another previously submitted study, or if it
responds to EPA questions raised with respect to an earlier
study, include 9n the title page elements a. through d. for the
previ9usly submitted study, along with the EPA Master Record
Identifier (MRID) or Accession number of the earlier study if you
know these numbers.   (Supplements submitted in the same submittal
package as the primary study should be appended to and bound with
the primary stuay.  Do not include supplements to more than one
study under a single title page).

g.    Facts of Publication.  If the study is a reprint of a pub-
lished d9cument, identity on the title page all relevant facts of
publication,  such as the J9urnal title, volume, issue, inclusive
page numbers, and publication date.


D.2. Statements of Data Confidentiality Claims Under FIFRA
§10(d) (1) .

     Each submitted study must be accompanied by one of the two
alternative forms of the statement of Data Confidentiality Claims
specified in the proposed regulation in §158.33 (b) and (c)    (See
Attachment 3).   These statements apply only to claims of data
confidentiality based on FIFRA §10(d)(1)(A), (B),  or  (C).   Use
the appropriate alternative form of the statement either to
assert a claim of §10(d)(l) data confidentiality  (§158.33(b)) or
to waive such a claim (§158.33(c)).  In either case, the
statement must be signed and dated, and must include the typed
name and title of the official who signs it.  Do not make CBI
                                98

-------
claims with respect to analytical methods associated with pet-
itions for tolerances or emergency exemptions  (see NOTE Pg 13).

D.3. Confidential Attachment

     If the claim is made that a study includes confidential
business information as defined by the criteria of FIFRA
§10(D)(1)(A),   (B),  or (C) (as described in D.2. above) all such
information must be excised from the body of the study and
confined to a separate study-specific Confidential Attachment.
Each passage of CBI so isolated must be identified by a reference
number cited within the body of the study at the point from which
the passage was excised  (See Attachment 5).

     The Confidential Attachment to a study must be identified by
a cover sheet fully identifying the parent study, and must be
clearly marked "Confidential Attachment."  An appropriately
annotated photocopy of the parent study title page may be used as
this cover sheet.  Paginate the Confidential Attachment
separately from the body of the study, beginning with page 1 of X
on the title page.   Each passage confined t9 the Confidential
Attachment must be associated with a specific cross reference to
the page(s) in the main body of the study on which it is cited,
and with a reference to the applicable passage(s) of FIFRA
§10(d)(1)  on which the confidentiality claim is based.

D.4. Supplemental Statement of Data Confidentiality Claims (See
     Attachment 4)
     If you wish to make a claim of confidentiality for any
 )ortion of a submitted study other than described by FIFRA £
 [I)(A),  (B),  or  (C),  the following provisions apply:
     - The specific information to which the claim applies must
     be clearly marked in the body of the study as subject to a
     claim of confidentiality.

     - A Supplemental Statement 9f Data Confidentiality Claims
     must be submitted, identifying each passage claimed confi-
     dential and describing in detail the basis for the claim.
     A list of the points to address in such a statement is
     included in Attachment 4 on Pg 14.

     - The Supplemental Statement of Data Confidentiality Claims
     must be signed and dated and must include the typed name and
     title of the official who signed it.

D.5. Good Laboratory Practice Compliance Statement

     This statement is required if the study contains laboratory
work subject to GLP requirements specified in 40 CFR 160.  Sam-
ples of these statements are shown in Attachment 6.

E.    Reference to Previously Submitted Data

     DO NOT RESUBMIT A STUDY THAT HAS PREVIOUSLY BEEN SUBMITTED
FOR ANOTHER PURPOSE unless EPA specifically requests it.   A copy
of the title page plus the MRID number (if known)  is sufficient
to allow us t9 retrieve the study immediately for review.  This
prevents duplicate entries in the Agency files, and saves you
the cost of sending more copies of the study.  References to pre-
viously submitted studies smpuld not be included in the transmit-
tal document, but should be incorp9rated into the statement of
the method of support for the application.

F.    Physical Format Requirements

     All elements in the data submittal package must be on
uniform 8 1/2 by 11 inch white paper, printed 9n one side only in
black ink, with high contrast and good res9lution.  Bindings for
individual studies must be secure, but easily removable to permit


                                99

-------
disassembly for microfilming.  Check with EPA for special
instructions bef9re submitting data in any medium other than
paper, such as film or magnetic media.

Please be particularly attentive to the following points:

     €    Do not include frayed or torn pages.

     €    Do not include carbon copies, or copies in other than
          black ink.

     €    Make sure that photocopies are clear,  complete, and
          fully readable.

     €    Do not include oversize computer printouts or fold-out
          pages.

     €    Do not bind any documents with glue or binding tapes.

     €    Make sure that all pages of each study, including any
          attachments or appendices, are present and in correct
          sequence.

     Number of Copies Required - All submittal packages except
those associated with a Registration Standard or Special Review
(See Part G below)  must be provided In three complete,  identical
copies.  (The prop9sed regulati9ns specified two copies; three
are now being required to expedite and reduce the cost of
processing data into the OPP Pesticide Document Management System
and getting it into review.)

G.   Special Requirements for Submitting Data to the Docket

     Data submittal packages associated with a Registration Stan-
dard 9r Special Review must be provided in four C9pies, fr9m one
of which all material claimed as CBI has been excised.   This
fourth copy will become part of the public docket for the RS or
SR case.  If no claims of confidentiality are made for the study,
the fourth copy should be identical to the other three.  When
portions of a study submitted in support of an RS or SR are
claimed as CBI, the first three copies will include the CBI
material as provided in section D of this notice.  The following
special preparation is required for the fourth copy.

     €    Remove the "Supplemental Statement of Data
          Confidentiality Claims".

     €    Remove the "Confidential Attachment".

     €    Excise from the body of the study any information you
          claim as confidential, even if it does not fall within
          the scope of FIFRA §10(d)(1)(A),  (B),  or  (C).  Do not
          close up or paraphrase text remaining after this
          excision.

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

             STATEMENT OF DATA  CONFIDENTIALITY  CLAIMS

NOTE: Applicants for  permanent or temporary tolerances  should
note that  it is OPP policy that no permanent tolerance,  temporary
tolerance,  or request for an emergency  exemption incorporating an
analytical  method, can be approved unless the applicant  waives
all claims  of confidentiality for the analytical method.   These
analytical  methods are published in the FDA Pesticide Analytical
Meth9ds  Manual, and therefore cannot be claimed as confidential.
OPP implements this policy by returning submitted analytical
methods,  for which confidentiality claims have been  made,  to the
submitter,  to obtain  the  confidentiality waiver before  they can
be processed.

      SUPPLEMENTAL STATEMENT OF DATA CONFIDENTIALITY CLAIMS
     For any portion of a submitted study that is not described
by FIFRA §10(d)(1)(A), (B),  or (C),  but for which y9u claim
C9nfidential treatment 9n another basis, the following informa-
tion must be included within a Supplemental Statement of Data
Confidentiality Claims:

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

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

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

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

     €    Describe the extent to which the information has been
          disclosed, and what precautions have been taken in con-
          nection with those disclosures.

     €    Encl9se C9pies of any pertinent determinations of
          confidentiality made by EPA, other Federal agencies, of
          courts concerning this information.

     €    If y9u assert that disclosure of this information would
          be likely to result in substantial harmful effects to
          you, describe th9se harmful effects and explain why
          they should be viewed as substantial.

     €    If you assert that the informati9n in voluntarily sub-
          mitted, indicate whether you believe disclosure of this
          information might tend to lessen the availability to
          EPA of similar information in the future, and if so,
          how.

                          PR NOTICE 91-2

         NOTICE  TO MANUFACTURERS,  PRODUCERS,  FORMULATORS,
                  AND REGISTRANTS OF PESTICIDES

ATTENTION: Persons Responsible for Federal Registration of
Pesticide Products.

SUBJECT: Accuracy of Stated Percentages for Ingredients
Statement

I.  PURPOSE:

     The purpose of this notice is to clarify the Office of
Pesticide Program's P9licy with respect to the statement of
percentages in a pesticide's label's ingredient statement.
Specifically, the amount  (percent by weight) of ingredient(s)
specified in the ingredient statement on the label must be stated
as the nominal concentration of such ingredient(s), as that term
is defined in 40 CFR 158.153(1).  Accordingly, the Agency has
established the nominal concentration as the only acceptable
label claim for the amount of active ingredient in the product.

II.  BACKGROUND

     For some time the Agency has accepted two different methods
9f identifying on the label what percentage is claimed for the
ingredient(s) contained in a pesticide. Some applicants claimed a
percentage which represented a level between the upper and the
lower certified limits. This was referred to as the nominal
concentration. Other applicants claimed the lower limit as the
percentage of the ingredient(s) that would be expected to be
present in their product at the end of the product's shelf-life.
Unfortunately, this led to a great deal of confusion among the
regulated industry, the regulators, and the consumers as to
exactly how much of a given ingredient was in a given product.
The Agency has established the nominal concentration as the only
acceptable label claim for the amount of active ingredient in the
product.

     Current regulations require that the percentage listed in
the active ingredient statement be as precise as possible
reflecting go9d manufacturing practices 40 CFR 156.10(g)(5). The
certified limits required for each active ingredient are intended
to encompass any such "good manufacturing practice" variations 40
CFR 158.175(c)(3).

     The upper and lower certified limits, which must be proposed
in connection with a product's registration, represent the
amounts of an ingredient that may legally be present 40 CFR
158.175. The lower certified limit is used as the enforceable
lower limit for the product composition according to FIFRA
section 12(a)(1)(C),  while the nominal concentration appearing on
the label would be the routinely achieved concentration used for
calculation of dosages and dilutions.

     The nominal concentration would in fact state the greatest
degree of accuracy that is warranted with respect to actual


                               111

-------
product compositi9n because the nominal concentration would be
the amount of active ingredient typically found in the product.

     It is imp9rtant for registrants to note that certified
limits for active ingredients are not considered to be trade
secret information under FIFRA section 10(b).  In this respect the
certified limits will be routinely provided by EPA to States for
enforcement purposes, since the nominal concentration appearing
on the label may not represent the enforceable composition for
purposes of section 12(a)(1)(C).

III. REQUIREMENTS

     As described below under Unit V. " COMPLIANCE SCHEDULE," all
currently registered products as well as all applications for new
registration must comply with this Notice by specifying the
nominal C9ncentrati9n expressed as a percentage by weight as the
label claim in the ingredient(s)  statement and equivalence
statements if applicable (e.g., elemental arsenic, metallic zinc,
salt of an acid).  In addition, the requirement for performing
sample analyses of five or more representative samples must be
fulfilled. C9pies of the raw analytical data must be submitted
with the nominal ingredient label claim. Further information
about the analysis requirement may be found in the 40 CFR
158.170. All products are required to pr9vide certified limits
for each active, inert ingredient, impurities of toxicological
significance(i.e.,  upper limit(s) 9nly) and on a case by case
basis as specified by EPA.  These limits are to be set based on
representative sampling and chemical analysis(i.e., quality
control) of the product.

     The format of the ingredient statement must conform to 40
CFR 156-Labeling Requirements For Pesticides and Devices.

     After July 1,  1997, all pesticide ingredient Statements must
be changed to nominal concentration.

IV. PRODUCTS THAT REQUIRE EFFICACY DATA

     All pesticides are required to be efficacious. Therefore,
the certified lower limits may not be lower then the minimum
level to achieve efficacy.  This is extremely important for
products which are intended to C9ntrol pests which threaten the
public health, e.g., certain antimicrobial and rodenticide
products. Refer to 40 CFR 153.640.

     In those cases where efficacy limits have been established,
the Agency will not accept certified lower limits which are below
that level for the shelf life of the product.

V. COMPLIANCE SCHEDULE

     As described earlier,  the purpose of this Notice is to make
the registration process more uniform and more manageable for
both the agency and the regulated community. It is the Agency's
intention to implement the requirements of this notice as
smoothly as possible so as not to disrupt or delay the Agency's
high priority programs,  i.e.,  reregistration,  new chemical, or
fast track (FIFRA section 3(c)(3)(B). Therefore,
applicants/registrants are expected to comply with the
requirements of this Notice as follows:

     (1)  Beginning July 1, 1991, all new product registrations
          submitted to the Agency are to comply with the
          requirements of this Notice.
                               112

-------
     (2)  Registrants having products subject to reregistration
          under FIFRA section 4(a) are to comply with the
          requirements of this Notice when specific products are
          called in by the Agency under Phase V of the
          Reregistration Program.

     (3)  All other products/applications that are not subject to
          (1) and  (2) ab9ve will have until July 1, 1997, to
          comply with this Notice. Such applications should note
          "Conversion to Nominal Concentrations on the
          application form. These types Or amendments will not be
          handled as "Fast Track" applications but will be
          handled as routine requests.

Data Call-in Response Forms (Attachment 2), indicating your election of this option.
Voluntary cancellation is item number 5 on both Data Call-In Response Form(s). If you
choose this option, these are the only forms that you are required to complete.

       If you chose to voluntarily cancel your product, further sale and distribution of your
product after the effective date of cancellation must be in accordance with the Existing Stocks
provisions of this Notice, which are contained in Section IV-C.

       b.     Use Deletion -

       You may avoid the requirements of this Notice by eliminating the uses of your product
to which the requirements apply. If you wish to amend your registration to delete uses, you
must submit the Requirements Status and Registrant's Response Form (Attachment 3), a
completed application tor amendment, a copy of your proposed amended labeling, and all
other information required for processing the application.  Use deletion is option number 7
under item 9 in the instructions for the Requirements Status and Registrant's Response Forms.
You must also complete a Data Call-In Response Form by signing the certification, item
number 8.  Application forms tor amending registrations may be obtained from the
Registration Support Branch, Registration Division,  Office of Pesticide Programs, EPA,  by
calling (703)      ~~-~
       If you choose to delete the use(s) subject to this Notice or uses subject to specific data
requirements, further sale, distribution, or use of your product after one year from the due
date of your 90 day response, is allowed only if the product bears an amended label.

       c.     Generic Data Exemption -

       Under section 3(c)(2)(D) of FIFRA, an applicant for registration of a product is
exempt from the requirement to submit or cite generic data concerning  an active ingredient if
the active ingredient in the product is derived exclusively from purchased,  registered pesticide
products containing the active ingredient.  EPA 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:

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


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

       (iii). 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, Attachment 2 and all supporting documentation. The Generic Data Exemption
is item number  6a on the  Data Call-in Response Form. If you claim a generic data exemption
you are not required to compiete the Requirements Status and Registrant's  Response Form.
Generic Data Exemption  cannot be selected as an option tor responding to  product specific
data requirements.

       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^) who have committed to
generate and submit the required data fail to take appropriate  steps to meet requirements or are
no longer in compliance with this Data Call-In Notice, the Agency will consider that both they
and you are not compliance and will normally initiate proceedings to suspend the registrations


                                          120

-------
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.

       If you acknowledge  on the Generic Data Call-In Response Form that you agree to
satisfy the generic data requirements (i.e. you select item number 6b), then you must select
one of the six options on the Generic Requirements Status and Registrant's Response Form
related to data production for each  data requirement.  Your option selection should be entered
under item number 9, "Registrant Response." The six options related to data production are
the first six options discussed under item 9 in the instructions for completing the Requirements
Status and Registrant's Response Form. These six options are listed
immediately below with information in  parentheses to guide you to additional instructions
provided in this Section. The options are:

       (1)    I will generate and submit data within the specified timeframe (Developing
             Data)
       (2)    I have entered into an agreement with one or more registrants to develop data
             jointly (Cost  Sharing)
             I have made offers to cost-share  (Offers to Cost Share)
             I am submitting an existing study that has not been submitted previously to the
             Agency by anyone (Submitting an Existing Study)
       (5)    I am submitting or citing data to upgrade a study classified by EPA as partially
             acceptable and upgradeable (Upgrading a Study)
       (6)    I am citing an existing study that EPA has classified as acceptable or an existing
             study that has been submitted but not reviewed by the Agency (Citing an
             -i-i.-i.   Oj_1\                                      OJVO
             Existing Study)

Option 1. Developing Data

       If you choose to develop the required data it must be in conformance with Agency
deadlines and with other Agency requirements as referenced herein and in the attachments. All
data  generated and submitted must comply with  the Good Laboratory Practice (GLP) rule (40


                                          122

-------
CFR Part 160), be conducted according to the Pesticide Assessment Guidelines (PAG) and be
in conformance 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 and/or footnotes to the form. If you wish to use a protocol which differs from
the options discussed in Section II-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 II-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.  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 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 Form 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 requirements(s),  you must submit a request to
the Agency which includes: (1)  a detailed description of the expected difficulty and (2) a
proposed schedule  including alternative dates for meeting such requirements on a step-by-step
basis. You must explain any technical or laboratory difficulties and provide documentation
from the laboratory performing the testing. While EPA is considering your request, the
original deadline remains. The Agency will respond to your request in writing. If EPA does
not grant your request, the  original deadline remains. Normally, extensions can be requested
only in  cases of extraordinary testing problems beyond the expectation or control of the
registrant. Extensions will not be given in  submitting the 90-day responses. Extensions will
not be considered if the request for extension is not made in a timely fashion; in no event shall
an extension request be considered if it is submitted at or after  the lapse of the subject
deadline.

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.
                                           123

-------
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 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^)  developing the data  has refused to accept the offer. To qualify for this option, you
must submit documentation to the Agency proving that you have made an offer to another
registrant (who has an obligation to submit data) to share in the burden of developing that
data. You must also submit to the Agency a completed EPA Form 8570-32, Certification of
Offer to Cost Share in the  Development of Data, Attachment 7.  In addition, you must
demonstrate that the other  registrant to whom the offer was made has not accepted your offer
to enter into a cost-sharing agreement by including a copy of your offer and proof of the other
registrant's receipt of that  offer (such as a certified mail  receipt).  Your offer must, in addition
to anything else, offer to share in the burden of producing the data upon terms to be agreed to
or, failing agreement,  to be bound by binding arbitration as provided by FIFRA section
3(c)(2)(Bj(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 burden of developing the data. In addition, the other registrant must fulfill
its commitment to develop and submit the data as required by this Notice.  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 normally will be subject to initiation of
suspension proceedings, unless you commit to submit, and do submit, the required data in the
specified time  frame. In such cases, the Agency generally will not grant a time extension  for
submitting the data.

Option 4. Submitting an Existing Study

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

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


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

       a.      You must certify at the time that the existing study is submitted that the raw
              data and specimens from the study are available for audit and review and you
              must identify where they are available. This must be done in accordance with
              the requirements of the Good  Laboratory Practice  (GLP) regulation, 40  CFR
              Part 160. As stated in 40 CFR 160.3  '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


                                           124

-------
              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, means "any material derived from a test system for examination or
              analysis."

       b.      Health and safety studies completed after May 1984 also must also contain all
              GLP-required quality assurance and quality control information, pursuant to the
              requirements or 40 CFR Part 160. Registrants also must 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 usually are  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 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 which 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 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.
                                           125

-------
Option 5.  Upgrading a Study

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

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

       This option also should 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  nurriber 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.

       2.  Product Specific Data

       If you acknowledge on the product specific Data Call-in Response Form that you agree
to satisfy the product specific data requirements (i.e. you select option (a or Yb), then you
must select one of the six options on the Requirements Status and Registrant's  Response Form
related to  data production for each data requirement.  Your option selection should be entered
under item number 9, "Registrant Response." The six options related to data production are
the first six options discussed under  item 9 in the instructions for completing the Requirements
Status and Registrant's Response Form.  These six options are listed immediately below with
information in parentheses to guide registrants to additional instructions provided in this
Section. The options are:

       (1)    I will generate and submit data within the specified time-frame (Developing
              Data)
       (2)    I have entered into  an agreement with one or more registrants to develop data

                    (Cost Sharing)
             1 have made offers to cost-share (Offers to Cost Share)
             I am submitting an existing study that has not been submitted previously to the
             Agency by anyone (Submitting an Existing Study)
       (5)    I am submitting or citing data to upgrade a study classified by EPA as partially
             acceptable and upgradeable (Upgrading a Study)
       (6)    I am citing an existing study that EPA has classified as acceptable or an existing
             study that has been
             submitted but not reviewed by the Agency (Citing an Existing Study)

Option 1. Developing Data — The requirements for developing product specific data are the
same as those described for generic data (see Section III.C.I, Option 1) except that normally
no protocols or progress reports are required.

Option 2. Agree to Share in Cost to Develop Data — If you enter into an agreement to cost
share, the same requirements apply to product specific data as to generic data (see Section
III.C.I, Option 2). However, registrants may only choose this option for acute toxicity data
and certain efficacy data and only if EPA has  indicated in the attached data tables that  your
product and at least one other product are similar for purposes of depending on
the same data. If this is the case, data may be generated for just one of the products in the
group. The registration number of the product for which data will be submitted must be noted
in the agreement to cost share by the registrant selecting this option.

Option 3. Offer to Share in the Cost of Data Development —The same requirements for
generic data (Section lll.C.l., Option 3)  apply to this option. This option only applies  to acute
toxicity and certain efficacy data as described in option 2 above.

Option 4. Submitting an Existing Study — The same requirements described for generic data
(see Section lll.C.l" Option 4) apply to this option for product specific data.

Option 5. Upgrading a  Study — The same requirements described for generic data (see Section
lll.C.l., Option b) apply to this option for product specific data.

Option 6. Citing Existing Studies — The same requirements described for generic data (see
Section lll.C.l" Option 6) apply to this  option for product specific data.

       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, and in the generic data requirements
section (lll.C.l.), as appropriate.


III-D REQUESTS FOR DATA WAIVERS

       1.     Generic Data

       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 not appropriate for your product.

       a.     Low Volume/Minor Use Waiver

             Option 8 under item 9 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 low volume pesticides to be only those active ingredients 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


                                           127

-------
pesticide, and the exposure and risk from use of the pesticide. If an active ingredient is
used for both high volume and low volume uses, a low volume exemption will not be
approved. If all uses of an active ingredient 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 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 for  a low volume, minor use waiver, you must submit the following
information, as applicable to your product(s), as part of your 90-day response to this
Notice:

       (i). Total company sales (pounds and dollars)  of all  registered product(s)
containing the active ingredient.  If applicable to the active ingredient, include foreign
sales for those products that are  not 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.

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

       (iii)  Total  direct production cost of product (s) containing the active ingredient
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.

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

       (v) 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.

       (vi)  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.

       (vii)  For each of the next ten years, a year-by-year forecast of company sales
(pounds and dollars) of the active ingredient, direct production costs of product (s)
containing the active ingredient (following the parameters in item 2 above), indirect
production costs of product(s) containing the active ingredient (following the
parameters in item 3 above), and costs of data development pertaining to the  active
ingredient.
                                    128

-------
       (viii)  A description of the importance and unique benefits of the active
ingredient to users. Discuss the use patterns and the effectiveness of the active
ingredient relative to registered alternative chemicals and non-chemical control
strategies. Focus on benefits unique to the active ingredient, providing information that
is as quantitative as possible.  If you do not have quantitative data upon which to 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 in terms of  its
benefits, you should provide information on any of the following factors,  as applicable
to your product(s):  (a) documentation of the usefulness of the active ingredient in
Integrated Pest Management,  (b) description of the beneficial impacts on the
environment of use of the active ingredient, as opposed to its registered alternatives,
(c) information on the breakdown of the active ingredient 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.

b.      Request for Waiver of Data

       Option 9, under Item 9, on the Requirements Status and Registrant's Response
Form. This option may be used if you believe that a particular data requirement should
not apply because the requirement  is inappropriate. You must submit a rationale
explaining why you believe the data requirements should not apply. You also must
submit the current label(s) of your product(s)  and, if a current copy of your
Confidential Statement of Formula is not already on file you must submit a current
copy.

       You will be informed  of the Agency's decision in writing. If the Agency
determines that the data requirements of this Notice are not appropriate to your
product(s), you will not be required to supply the data pursuant to section 3(c)(2)(B). If
EPA determines that the  data are required for your product(s)  you must choose a   ~~
method of meeting the requirements of this Notice within the time frame provided by
this Notice.  Within 30 days of your receipt of the Agency's written decision, you must
submit a revised Requirements Status and Registrant s Response Form indicating the
option chosen.

2. Product Specific Data

       If you request a waiver for  product specific data because you believe it is
inappropriate, you must attach a complete justification for the request including
technical reasons, data and references to relevant EPA regulations,  guidelines or
policies. (Note: any supplemental data must be submitted in the format required by PR
Notice 86-5). This will be the only opportunity to state the reasons  or provide
information  in support of your request. If the Agency approves your waiver request,
you will not be required to supply  the data pursuant to section 3(c)(2)(B) of FIFRA.  If
the Agency denies your waiver request,  you must choose an option for meeting the data
requirements of this Notice within  30 days of the receipt of the Agency's decision.
You must indicate and submit the option chosen on the product specific Requirements
Status and Registrant's Response Form.  Product specific data requirements tor 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.
                                    129

SECTION IV.       CONSEQUENCES OF FAILURE TO COMPLY WITH THIS
                    JNUTHJK

IV-A  NOTICE OF INTENT TO SUSPEND

       The Agency may issue a  Notice of Intent to Suspend products subject to this Notice due
to failure by a registrant to comply with the requirements of this Data Call-in Notice, pursuant
to FIFRA section 3 (c) (2) (B). Events which may be the basis for issuance of a Notice of Intent
to Suspend include, but are not limited to, the following:

       1.     Failure to respond as required by this Notice within 90 days  of your receipt of
             this Notice.

       2.     Failure to submit  on the required schedule an acceptable proposed or final
             protocol when such is required to be submitted to the Agency for review.

       3.     Failure to submit  on the required schedule an adequate progress report on a
             study as required  by this Notice.

       4.     Failure to submit  on the required schedule acceptable data as required by this

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 of any changes required by the Agency following review.

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

IV-C  EXISTING STOCKS OF SUSPENDED OR CANCELLED PRODUCTS

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

       The Agency has determined that such disposition by  registrants of existing stocks for a
suspended registration when a section  3 (c) (2) (B) data request is outstanding generally would
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 also  must 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 a 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


                                           131

-------
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
                   LJJMREASONABLE 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.

item number 3 ("Date and Type of DCI") on each form.  BOTH "Data Call-In Response"
forms must be completed.

       Although the form is the same for both generic and product specific data, instructions
for completing these forms are different. Please read these  instructions carefully before filling
out the forms.

       EPA has developed these forms individually for each registrant, and has preprinted
these forms with a number of items. DO NOT use these forms for any other active
ingredient.

       Items  1 through 4 have been preprinted on the form.  Items 5 through 7 must be
completed by the registrant as appropriate.  Items 8 through 11 must be completed by the
registrant before submitting a response to the Agency.

       The public reporting burden for this collection of information is estimated to average
15 minutes per response, including time for reviewing instructions, searching existing data
sources, gathering and maintaining the data needed, and completing and reviewing the
collection  of information. Send comments regarding the burden estimate or any other aspect of
this collection of information, including suggestions for reducing this burden, to Chief,

EPA'S BATCHING  OF PRODUCTS  CONTAINING D-LIMONENE AS THE ACTIVE
INGREDIENT FOR  MEETING ACUTE  TOXICITY  DATA  REQUIREMENTS FOR
REREGISTRATION

   In an effort to reduce the time, resources and number of animals needed to fulfill the acute toxicity
data requirements  for reregistration of products containing the active ingredient d-limonene  (1-
Methyl-4-(l-methylethenyl) cyclohexene) the Agency has batched products which 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., emulsifiable concentrate, aerosol, wettable powder, 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 toxicity data 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 lexicological 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 batch,  or  to  generate all the required  acute
lexicological 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 toxicity data, he/she may do so provided that the
data base  is complete and valid by today's  standards  (see acceptance criteria attached),   the
formulation tested is considered by EPA to be similar for acute toxicity, and the formulation has not
been significantly altered since submission and acceptance of the acute toxicity data. Regardless of
whether new data is generated or existing data is referenced,  registrants must clearly identify the  test
material by EPA Registration Number.  If more than one confidential statement of formula (CSF)
exists for a product, the registrant must indicate the formulation actually tested by identifying the
corresponding CSF.

    In deciding how to meet the product  specific data requirements, registrants must follow  the
directions given in the Data Call-in Notice and its attachments appended to the RED. The DCI Notice
contains two response forms which 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 toxicity 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 following options: Developing Data (Option 1), Submitting an Existing
Study (Option 4), Upgrading an Existing Study (Option 5) or Citing an Existing Study (Option 6).
If a registrant depends on another's  data, he/she must choose among: Cost Sharing (Option 2), Offers
to Cost Share (Option  3) or Citing an Existing Study (Option 6). If a registrant does  not want to
participate in a batch, the choices are Options 1, 4, 5 or 6. However, a registrant should know that
choosing not to participate in a batch does not preclude other registrants in the batch from citing
his/her studies and offering to cost share (Option 3) those studies.

Table 2 lists those products the Agency was unable to batch.  These products were either considered
not to be similar to other products for purposes of acute toxicity or the Agency lacked sufficient
information for decision making.  Registrants of these products are responsible for meeting the acute
toxicity data requirements for each product.

     Pesticide
Reregistration
   Use Profile
     All pesticides sold or distributed in the United States must be
registered by EPA, based on scientific studies showing that they can be used
without posing unreasonable risks to people or the environment. Because of
advances in scientific knowledge, the law requires that pesticides which
were first registered years ago be reregistered to ensure that they meet
today's more stringent standards.
     In evaluating pesticides for reregistration, EPA obtains and reviews a
complete set of studies from pesticide producers,  describing the human
health and environmental effects of each pesticide. The Agency imposes
any regulatory controls that are needed to effectively manage each
pesticide's risks.  EPA then reregisters pesticides that can be used without
posing unreasonable risks to human health or the environment.
     When a pesticide is eligible for reregistration, EPA announces this and
explains why in a Reregistration Eligibility Decision (RED) document.  This
fact sheet summarizes the information in the RED document for
reregistration case 3083,  limonene.

     Limonene is a naturally occurring chemical which is used in many
food products, soaps and perfumes for its lemon-like flavor and odor.
Limonene also is  a registered active ingredient in 15 pesticide products used
as insecticides, insect repellents, and dog and cat repellents.
     Pesticide products containing limonene are used for flea and tick
control on pets, as an insecticide spray, an outdoor dog and cat repellent, a
fly repellent tablecloth, a mosquito larvicide,  and an insect repellent for use
on humans.  Formulations include ready-to-use solutions, emulsifiable
concentrates, granulars and impregnated material. Limonene is applied by
hand as needed, both indoors and outdoors.  Use practice limitations include
a label prohibition against use on weanling kittens and a caution against use
of undiluted product.

-------
    Regulatory
        History
Human Health
  Assessment
     Limonene was first registered as a insecticide in the U.S. in 1958.  It
was registered as an antimicrobial in 1971, and as a dog and cat repellent in
1983.  In May 1988, EPA announced that limonene is considered an inert
rather than an active ingredient when used in antimicrobial products (please
see 40  CFR 153.139(a)).  In April 1994, limonene was granted an
exemption from the requirement of a tolerance  (or maximum residue limit)
when it is an inert ingredient used as a solvent or fragrance in  pesticide
formulations (please see 40 CFR 180.1001 (c), (e)).  The Food and Drug
Administration (FDA) lists limonene as Generally Recognized  as Safe
(GRAS) as a food additive or flavoring and a fragrance additive (please see
21 CFR 182.60).  Currently, 15 limonene pesticide products are registered.
     Limonene is among those pesticide active ingredients for which a
reduced set of generic data requirements is appropriate for registration or
reregistration. Limonene is naturally occurring, has been established as an
inert, is exempt from the requirement of a  tolerance, and is recognized as
safe by FDA.  Its effects are well known and documented in scientific
literature; additional testing would not likely provide any new  findings.
Adequate information is available to characterize its risks to humans and
animals.
Toxicity
     Limonene is of relatively low acute toxicity taken orally.   It is  a
dermal irritant when applied at high concentrations and may cause dermal
sensitization. A 90-day dermal toxicity study using the formulated product
is required as confirmatory data to support reregistration of the insect
repellent that is to be applied directly to  human skin.
     A subchronic  study by the National Toxicology Program (NTP) using
rats and mice resulted in decreased body weights, kidney disease and
mortality at the highest dose tested.  A chronic toxicity study by NTP using
rats resulted in decreased body weight, kidney disease and kidney tumors,
which occurred due to a species-specific mechanism.  Limonene is not
considered a human carcinogen, a developmental toxicant or mutagenic.
Dietary Exposure
     Limonene occurs naturally in citrus and other fruits, vegetables, meats
and spices.  It also is used in a variety of foods and beverages  (as well as in
soaps and perfumes) to add lemon-like flavor and aroma.  FDA considers
limonene Generally Recognized as Safe (GRAS) as a food additive or
flavoring, and as a fragrance additive.  EPA has granted limonene an
exemption from the requirement of a tolerance when it is used as an inert
ingredient in pesticide formulations, and when used as an insect repellent
tablecloth.
     As a pesticide active ingredient, limonene is not registered for food or
feed crop uses and is not expected to result in dietary exposure.

-------
Environmental
  Assessment
Occupational and Residential Exposure
     People and pets may be exposed to limonene during and after
application in household settings.  Human exposure may occur during
application of pet flea products, animal repellent granules or insecticide
sprays, or during use of insect repellent impregnated tablecloths.
Toxicologic concerns for humans from these  exposures include skin
irritation and sensitization.  Ocular irritation also may occur if limonene
products accidentally enter the eye and are not washed away.
     Limonene is used in several shampoo, dip and spray products applied
dermally to domestic animals to control fleas and ticks.   Adverse reactions
have been reported in a small percentage of animals, especially cats,
following exposure to limonene products. Kittens and young cats seem to
be most sensitive. Product labels bear precautionary statements warning of
the potential for dermal irritation, prohibiting use on weanling kittens,  and
cautioning against use of undiluted product on pets.
Human Risk Assessment
     Dietary exposure to limonene is not a concern.  Limonene occurs
naturally in foods, is used as a flavoring agent, is generally recognized  as
safe by FDA, and has only one food-related pesticide use (as an insect
repellent impregnating  tablecloths) that EPA has exempted from tolerance
requirements.
     People may be exposed to limonene when applying flea and tick
control shampoos, dips or sprays to their pets, when applying animal
repellent granules or insecticide sprays, or when using impregnated
tablecloths.  Skin irritation and sensitization or eye irritation may occur
from these uses.  In addition, adverse reactions may occur in some pets,
especially cats, treated  with the flea and tick  control products. Additional
precautionary statements are required on limonene product labeling to
reduce the potential for adverse effects among users and treated pets.

Environmental  Fate
     Limonene is insoluble  and is expected to be stable in water.
Ecological Effects
     Technical limonene is practically nontoxic to birds on a subacute
dietary basis, and is slightly  toxic to freshwater fish and invertebrates on an
acute basis.  The formulated product  is practically nontoxic to birds on an
acute and subacute dietary basis.  It is practically nontoxic to freshwater fish
and slightly toxic to freshwater invertebrates  on an acute basis. Based on
acute toxicity data using rats, limonene is practically nontoxic to mammals.

-------
   Additional Data
           Required
  Product Labeling
Changes Required
Ecological Effects Risk Assessment
     Potential risk to birds might occur from ingesting limonene granules
spread on lawns, sidewalks or driveways, or from consuming insects
contaminated with limonene.  However, based on the lack of toxicity of
limonene to birds, little risk is anticipated.
     Similarly, mammals are not likely to ingest a sufficient quantity of
limonene granules to be at risk, particularly since limonene is practically
nontoxic to mammals.
     The mosquito larvicide use of limonene produces an oily film that is
expected to dissipate rapidly, posing no major ecological concern for
freshwater invertebrates or other  aquatic species.  Minimal risks to aquatic
species, including endangered aquatic species, are expected from runoff into
pond water from applications  of the granular product.

     EPA is requiring a 90-day dermal toxicity study for the recently
registered limonene personal insect repellent product, to confirm its
regulatory assessments and conclusions. 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
reregistration.

     All limonene end-use products must comply with EPA's current
pesticide product labeling requirements, and with the following:
Environmental Hazard Statements
End-use products with the mosquito larvicide use must  bear the following
statement:
     "Do not contaminate water when disposing of equipment washwater or
     rinsate. Consult with your  State Agency in charge of fish and game
     before applying to public waters to determine if a permit is needed."
End-use products without the  mosquito larvicide use must bear the following
statement:
     "Do not apply directly to water,  or to areas where surface water is
     present or to intertidal areas below the mean high-water mark.  Do not
     contaminate water when disposing of equipment washwater or
     rinsate."
Precautionary Statements
     To reduce the risk of adverse effects which occasionally occur in pets
exposed to limonene flea and tick control products, and to reduce risks of
skin irritation/ sensitization to product users, the following strengthened
statements are required on labels  of products intended for use on domestic
animals:

-------
 Regulatory
Conclusion
   For More
Information
     Add:  "Applicators of flea and tick dip (concentrates), spray or
     shampoo products are to use protective gloves to reduce the risk of
     dermal irritation or dermal sensitization."
     Add:  "Flea dip concentrates may harm animals when used at greater
     strength than specified on the label."
     Change the age for product use on kittens/puppies to several months
     or a year.
     Change the statement, "Use with care on nursing animals," to "Do not
     use on nursing animals or any animal which is in poor health."
     Provide a list of symptoms which may occur when animals are
     sensitive to the product, to the precautionary statement, "Individual
     animals may be more sensitive to the product."

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

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