I.      Introduction

       The Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA) was amended in 1988
to accelerate the reregistration of products with active ingredients registered prior to November
1, 1984.  The amended Act calls for the development and submission of data to support the
reregistration of an active ingredient, as well as a review of all submitted data by the U.S.
Environmental Protection Agency (referred to as EPA or "the Agency").  Reregistration
involves a thorough review of the scientific database underlying a pesticide's registration. The
purpose of the Agency's review is to reassess the potential risks 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 or not the pesticide meets the "no
unreasonable adverse effects" criterion of FIFRA.

       This document summarizes EPA's human health and ecological risk assessments and
reregistration eligibility decision (RED) for triforine. The document consists of six sections.
Section I contains the regulatory framework for reregistration; Section II provides an overview
of the chemical  and a profile of its use and usage; Section III gives an overview of the human
health and environmental effects risk assessments; Section IV presents the Agency's decision
on reregistration eligibility and risk management; and Section V summarizes the label changes
necessary to implement the risk mitigation measures outlined in Section IV. Finally, the
Appendices list related information, supporting documents, and studies evaluated for the
reregistration decision. The risk assessments for triforine and all other supporting documents
are available in  the Office of Pesticide Programs (OPP) public docket at
http://www.regulations.gov under docket number EPA-HQ-OPP-2008-0196.

Chemical Overview
       A.     Regulatory History

       Triforine was first registered in the United States by American Cyanamid in 1976 for
use as a fungicide on ornamentals and a variety of food crops.  All food uses were voluntarily
cancelled in 1996 and the associated tolerances were revoked in a final rule published on July
23, 2004 (69 FR 43918) (FRL-7358-6). Outside the United States, triforine continues to be
used on food crops, turf, and ornamentals.  Summit Agro acquired the one technical product in
May 2005.

       A DCI was issued to the technical registrant in January 1991. Because of the many crop
uses of triforine this DCI included data requirements for ecological, environmental fate,
toxicology, and residue chemistry.  In the registrant's response to the DCI, they indicated that
they were no longer going to support the food uses of triforine and only maintain the non-food
uses. All indoor food uses and terrestrial food uses were removed from their labels.  In 1995, a
DCI was mailed to the remaining registrants of triforine to allow them the opportunity to
support these uses by submitting the required data.  In subsequent responses to the DCI, all
registrants removed food uses and only non-food uses now remain on the triforine labels.  In
October 1995 a DCI was mailed to the registrants which included data requirements for re-entry
exposure.

       There are currently four active Section 3 registrations for triforine. No tolerance exists
for commodities treated with triforine. Table 1 presents the supported registrations that contain
triforine as an active ingredient.

III.    Summary of Triforine Risk Assessments

       The purpose of this summary is to assist the reader by identifying the key features and
findings of these risk assessments, and to help the reader better understand the conclusions
reached in the assessments.  While the risk assessments and related addenda are not included in
this document they are available in the OPP Public Docket,  docket number EPA-HQ-OPP-
2008-0196, and may be accessed through http://www.regulations.gov/. Hard copies of these
documents may also be found in the OPP public docket under this same docket number.  The
human health and ecological risk assessments and supporting documents listed below and
referenced in Appendix C were used to formulate the regulatory decision for the pesticidal use
of triforine.

          Human Health Risk Assessment
       The human health risk assessment addressed potential exposure and risks from all
registered uses. Triforine is not registered for use on any food commodities and risk is not
expected from drinking water sources, due to its use pattern, its fate characteristics, the low
potential for drinking water exposure given the small-scale residential nature of the labeled use
and its toxicity profile.  Triforine products are sold predominantly in the residential marketplace
where it is used by gardeners to control various plant diseases primarily on roses but it can be
used on other ornamental plants.  For the complete human health risk assessment, refer to
Triforine: REVISED HED Chapter of the Reregistration Eligibility Decision Document
(Olinger, C. et al., Dated 3-11-08), which is available in the public docket.
              1.
                 Toxicity of Triforine
       The toxicological database for triforine is sufficient for risk assessment purposes.
Triforine has low to moderate (Category III) toxicity via the dermal route of exposure and is a
minor eye irritant (Category III).   It is not acutely toxic via the oral or inhalation routes of
exposure (Category IV), it is not a dermal irritant (Category IV) and is negative for skin
sensitization. Table 5 summarizes the acute toxicity profile of triforine.

       Effects observed in subchronic and chronic toxicity studies were generally not severe.
Liver effects included increased liver weights, increased cholesterol levels, and increased
alkaline phosphatase levels. A mild anemia was seen in several studies, apparently caused by
damage to red blood cells because the bone marrow responded by increasing production of red
blood cells.

       No maternal or developmental toxicity was observed in the rat in the developmental
toxicity study at significant dose levels. In the rabbit, decreased maternal body weight and food
consumption and decreased fetal body weight were the only effects observed at the limit dose.
Slight reproductive effects such as decrease in testes weight, were observed in the rat
reproduction study at doses above the limit dose.

       Developmental or reproductive toxic effects from triforine are not of concern.  Some
reproductive toxicity effects such as decreased testes weight, decreased male fertility, were
observed at doses higher than the limit dose.  No toxic reactions were observed in a 21-day
dermal toxicity study at doses up to 1100 mg/kg/day which is higher than the limit dose. It is
not a dermal sensitizer or dermal irritant.  Triforine does not appear to be neurotoxic and there
are no specific concerns for pre- and post-natal exposure to triforine. Therefore,  no uncertainty
factors specifically for children's pre- or post-natal exposures are included in the risk
assessment.

       Triforine has been classified as, "suggestive evidence of carcinogenicity,  but not
sufficient to assess human carcinogenic potential." This was based on tumors  seen in both
sexes of one species (mice) only at the limit dose (liver tumors in male mice and lung tumors in
female mice).  Therefore, there is no quantification of cancer risk for triforine.

       A point of departure is the data point or an estimated point that is derived from observed
dose-response data and used to mark the beginning of extrapolation to determine risk associated
with environmentally relevant human exposures. Table 6 contains selected points of departure
for the triforine human health risk assessments.
                                                                                     13

              2.     Exposure/Risk Pathway

Dietary Exposure

       Because the use of triforine on roses and other plants is a non-food use and all
tolerances from prior registrations have been revoked, there is no expectation of dietary
exposures through food consumption.  Therefore, the only dietary exposure considered in this
assessment is from drinking water. There are Maximum Residue Limits established for
triforine in other countries, and a list is included in the Triforine RevisedHED Chapter, page
16.

Drinking Water

       Triforine is moderately persistent in soil with a half-life of one to several months and it
degrades rapidly in water through hydrolysis and photolysis with half-lives of several days.
                                                                                         14

-------
Due to its rapid hydrolysis and aquatic photolysis, any triforine that reaches drinking water
sources would not be long-lived so there is a low probability of exposure.  Triforine is intended
for small-scale use by individual homeowners; it is marketed as either 14 oz spray cans or in
volumes of one pint to one quart, which can treat a maximum of 0.3 A. Use data from the
California Department of Pesticide Regulation (CDPR) suggests that typical use by professional
applicators is at rates of <0.05 Ib a.i./application. No water monitoring data are available for
triforine.

       Tier I screening level models were used to quantify the upper bound for drinking water
exposure by calculating estimated  drinking water concentrations (EDWCs). EDWCs are based
on the highly conservative assumption that an entire watershed has been treated with triforine at
the maximum application rate, so these values likely overestimate potential exposure.  The
EDWC for annual average exposure (from surface or ground water sources) is less than one
ppb. Considering the toxicity profile for triforine, the fate characteristics, the use pattern, and
the very low EDWC, there is no concern from dietary exposure in drinking water.

Residential (Non-Occupational) Handler Exposure and Risk

       Triforine is available as a consumer product used predominantly on roses for control of
black spot, powdery mildew, and rust.  Triforine can also be used on various ornamental and/or
shade trees as well as ornamental herbaceous plants, woody shrubs and vines.  The residential
risk assessment addresses inhalation exposures that individuals receive through their use of
consumer products that contain triforine and through inhalation exposures they could receive
from frequenting areas that have been previously treated with triforine such as park or home
ornamental gardens. No quantitative dermal assessment has been conducted because there were
no systemic effects observed in the 21-day dermal toxicity study at the limit dose.  Based on the
use pattern no incidental oral exposure is expected.

       Non-cancer risk estimates are expressed as a margin of exposure (MOE) which is a ratio
of the dose from a toxicological study selected for risk assessment, typically a NOAEL, to the
predicted exposure. Estimated MOEs are compared to a level of concern which reflects the
dose selected for risk assessment and uncertainty factors (UFs) applied to that dose.  The
standard UF is 100X, which includes 10X for interspecies extrapolation (to account  for
differences between laboratory animals and humans) and 10X for intraspecies variation (to
account for differences among humans).  For triforine, MOEs greater than 100 for inhalation
exposure do not exceed the Agency's level of concern.

       The anticipated use patterns and current labeling indicate several residential  exposure
scenarios, based on the types of equipment and techniques, in which homeowners can be
exposed to triforine during the application process. Intermediate- and long-term exposures are
not expected and were not calculated for residential handlers, because of the sporadic nature of
applications by homeowners.

       The quantitative inhalation risk assessment developed for residential handlers is based
on a number of scenarios that include handling liquid concentrates with various hand-held
application equipment as well as application with aerosol cans. Although there is information
                                                                                     15

-------
to suggest that triforine is not typically used in greenhouses, there is nothing on labels to
prohibit this use.  Since the rate of triforine used in greenhouses would be the same as the
outdoor use of triforine, the estimated risk would be the same as well. All of the residential
short-term handler inhalation scenarios have MOEs that are greater than the target MOE of 100
by a wide margin.  MOEs are greater than 50,000; therefore, the risks are below EPA's level of
concern. EPA evaluated both Pesticide Handlers Exposure Database (PHED) and Outdoor
Residential Exposure Task Force (ORETF) data for several of the handler scenarios. Both sets
of data result in a similar risk conclusion in that triforine risks are not of concern and by a
similar wide margin.

Residential (Non-Occupational) Post-application Exposure Assessment

       The term "post-application" describes exposure to individuals who enter areas
previously treated with pesticides. For triforine, a quantitative post-application risk assessment
was not conducted because (1) incidental  oral  exposure was not expected since the primary uses
of triforine are for disease control on roses and other ornamental plants where children would
not be expected to routinely contact treated plants and engage in mouthing behaviors; and (2)
triforine is relatively not volatile which, coupled with the dilution expected outdoors and the
small amounts of active ingredient used, diminish the possibility of post-application inhalation
exposure. Therefore, there is no concern for post-application exposures to triforine.

Aggregate Exposure and Risk

       There are no registered food uses for triforine and all tolerances for triforine have been
revoked. Due to the use of triforine and its environmental fate properties, significant drinking
water exposure is not expected. All the residential exposures do not exceed the Agency's level
of concern. Therefore, there is no concern for aggregate exposure to triforine.

Cumulative Risk Characterizing/Assessment

       EPA has  not identified a common  mechanism for triforine and any other substances.
Triforine does not appear to produce a toxic metabolite produced by other substances.

Occupational Exposure and Risk

       Although the primary marketplace for triforine is for residential gardeners, an
occupational assessment was conducted to ensure that if use by professionals did occur that the
anticipated higher daily use rates and frequency for occupational users would be considered.
Occupational exposures can occur because people have contact with triforine residues while
using commercial products  containing triforine (handlers) or by being in areas that have been
previously treated (post-application workers).  The only occupational exposure route included
in this risk assessment is the inhalation route.  Effects from dermal exposures are not expected.

       The scenarios associated with triforine use were classified as having short-term (from 1
to 30 days) and intermediate-term (from 30 days to several  months) exposures. However,
intermediate-term exposures for triforine are unlikely because of its limited use pattern, low
                                                                                      16

-------
historic use, and low frequency of use by commercial applicators. Long-term exposures are
also not expected to occur for the same reasons.

       The quantitative inhalation risk assessment developed for occupational handlers is based
on a number of scenarios that include handling liquid concentrates with various hand-held
application equipment as well as application with aerosol cans.  Although there is information
to suggest that triforine is not typically used in greenhouses, there is nothing on labels to
prohibit this use. Since the rate of triforine used in greenhouses would be the same as the
outdoor use of triforine, the estimated risk would be the same as well. All of the occupational
short- and intermediate-term handler inhalation scenarios have MOEs that are much greater
than the target MOE of 100. Without the use of a respirator, MOEs were greater than 9,000;
therefore, the risks are below EPA's level of concern. EPA evaluated both PHED  and ORETF
data for several of the handler scenarios. Both sets of data result in a similar risk conclusion in
that triforine risks are not of concern and by a similar wide margin.
B.     Environmental Risk Assessment

       The Agency has conducted an environmental fate and effects risk assessment for
triforine for the purpose of making a reregi strati on decision. The fate database for triforine is
largely complete. The available data are sufficient to characterize the transport, mobility, and
degradation of triforine in the environment.  The ecological database for triforine is largely
complete for terrestrial and aquatic animals. However, the ecological database for both aquatic
and terrestrial  plants is not complete and additional data is required. A summary  of the
environmental risk assessment findings and conclusions is provided below.  For more detail on
the ecological  exposure and risk assessment, see the Revised Level I Baseline Ecological Risk
Assessment for the Reregistration of Triforine (Moore, K., and Carey, S., Dated 03-05-08).

       1.      Environmental Fate and Transport

       The environmental fate database for parent triforine is largely complete but there are
gaps in identifying degradates and characterizing their fate. Triforine is a moderately mobile
compound (Kocis from 99 mL/goc to 199 mL/goc) that is moderately persistent in soil, with half-
lives on the scale of weeks to months, and has rapid abiotic degradation in aquatic
environments. Aquatic exposure may be to the degradates of triforine formed through
hydrolysis and photolysis. No physical/chemical or environmental fate data are available for
these degradates and ecological toxicity from these degradates are unknown. For the purposes
of this assessment, aquatic degradates are assumed to be as persistent and to have equal toxicity
as the parent.

       2.      Environmental Effects and Risk

       To estimate potential ecological risk, EPA integrated the results of exposure and
ecotoxicity studies using the risk quotient method.  Risk quotients (RQs) are calculated by
dividing exposure estimates by ecotoxicity values,  both acute and chronic, for various wildlife
species. RQs are then compared to the Agency's levels of concern (LOCs), indicating whether
                                                                                      17

-------
a pesticide, when used as labeled, has the potential to cause adverse effects on non-target
organisms (see Table 7 below). Generally, the higher the RQ, the greater the potential risk.
Risk characterization provides further information on the likelihood of adverse effects
occurring by considering the fate of the chemical in the environment, communities and species
potentially at risk, their spatial and temporal distributions, and the nature of the effects observed
in studies.

Aquatic Organism Risk

       The Agency used modeling to derive estimated environmental concentrations (EECs)
for triforine in surface water to represent a variety of aquatic habitats, such as ponds adjacent to
treated areas, which are relevant to risk assessment for aquatic animals.

Acute

       Available acute toxicity data indicate that triforine is no more than slightly toxic to
freshwater fish at the maximum solubility limit (LCso >11 mg ai/L) and moderately toxic to
freshwater invertebrates (ECso = 8.95 mg ai/L). Since a definitive acute toxicity threshold could
not be established for freshwater fish, RQs were not quantitatively estimated. Based on the
available information there is no indication of risk for freshwater fish from acute exposure to
triforine as a result of the labeled uses.  For freshwater invertebrates, RQs were estimated based
on the most conservative aquatic exposure scenario. The freshwater invertebrate RQ for acute
exposure is 0.03 and does not exceed the acute listed species LOC of 0.05.

       There is a potential for acute exposure to estuarine/marine fish and invertebrates, but
acute risks were not estimated because toxicity data were not available.  There are some
uncertainty regarding the potential acute risks to estuarine/marine fish and invertebrates;
however, given the limited residential use of triforine combined with the indication of minimal
risk for freshwater animals, acute risks to estuarine/marine fish and invertebrates are likely
minimal.

       There is only one non-vascular plant study available for triforine. A Tier II toxicity
study with green algae indicates that triforine adversely affects cell density. Based on the most
conservative aquatic exposure scenario for triforine, which assumes 20 applications at a rate of
0.46 Ibs. a.i./A, the peak EEC is 0.23 mg ai/L, the acute RQ for non-target plants is less than
0.01, which is well below the LOC of 1. Endangered species risk to aquatic non-vascular plants
could not be calculated because the green algae NOAEC was below the lowest concentration
                                                                                      18

-------
tested and an ECos as a surrogate could not be calculated without the raw data of individual
replicate measurements.

       Data are not available to evaluate the risk of triforine to aquatic vascular plants (i.e.,
duckweed). The potential impact to aquatic vascular plants from exposure to triforine is
unknown.  However, data from the open literature and a history of phytotoxicity incidents to
terrestrial vascular plants suggest that triforine may pose a risk to non-target aquatic vascular
plants. Additional data are required in order to assess the potential risk of triforine to aquatic
vascular plants.

Chronic

       Data were not available to evaluate the chronic risk of triforine to freshwater fish and
invertebrates or to estuarine/marine fish and invertebrates. Therefore, the potential risks to
these organisms are unknown. There is some uncertainty regarding the potential chronic risk to
these organisms.  Given the limited residential use of triforine combined with the indication of
minimal acute risk for freshwater animals, chronic risk to aquatic animals are likely minimal.

Terrestrial  Organism Risk

Birds

       Triforine is categorized as practically non-toxic to birds based on studies using upland
game birds (bobwhite quail) and waterfowl (mallard duck) on an acute oral basis (LD50 >2000
mg ai/kg-bw) and subacute dietary route (LD50 >5000 mg ai/kg-diet). Since definitive acute
oral toxicity thresholds were not established in the submitted toxicity studies, acute avian RQs
were not estimated for birds.  However, due to the high LDsos,  and relatively low potential for
exposure, birds are not at risk to adverse effects of survival from acute oral exposure to triforine
as a result of the labeled uses of triforine.

       For chronic exposure, bird species  are potentially at risk to adverse effects of growth
and reproduction from chronic dietary exposure to triforine as a result of the labeled uses.
Results of chronic studies with triforine indicate that waterfowl and upland game birds are
equally sensitive with reproductive effects of eggshell thinning and cracked eggs being
observed at 500 mg ai/kg-diet, resulting in a NOAEC of 100 mg ai/kg-diet. Based on the most
conservative terrestrial scenario with multiple (20) applications of triforine and maximum
predicted residue levels (upper bound EECs), chronic RQs range between 3.7 and 8.  This
exceeds the Chronic Risk LOG (LOG >1.0) for birds consuming short grass, tall grass,
broadleaf forage/small insects. For a single application of triforine, the Chronic Risk and
Endangered Species LOG of 1 is exceeded only for birds foraging short grass (RQ = 1.1).
Although there are exceedances of the chronic LOG, the potential for risk of adverse effects to
growth and reproduction is based on  the assumption that birds are feeding exclusively within
residential  areas where roses, flowers, shrubs, and shady trees are grown.  These exceedances to
birds are based on the assumption that birds occupy, exclusively and permanently, the area of
registered uses, and foraging feed items with triforine residues. To the extent that those birds
                                                                                       19

-------
do not reside exclusively and permanently within the area, exposure will be less and risk is
presumably less.

Mammals

       The acute LD50 (>5000 mg ai/kg bw) for mammals is greater than the highest
concentration tested, suggesting that triforine is practically non-toxic to mammals on an acute
oral basis.  Since a definitive acute toxicity threshold was not established, acute mammalian
RQs were not estimated; however, mammals are not likely to be at risk from acute oral
exposure to triforine as a result of the labeled uses.

       Results of chronic toxicity studies with rats indicated an NOAEC of 3000 mg ai/kg-diet
for reproductive and offspring effects. Based on the maximum application rate of triforine at
0.46 Ib ai/A and maximum predicted residue levels (upper bound EECs), the chronic risk and
endangered species LOG (LOG >1.0) is exceeded for 15 and 35 g mammals consuming short
grass at 7 and 8 applications, respectively.  Although there is an exceedance of the chronic
LOG, the potential for risk of adverse effects to growth and reproduction is based on the
assumption that mammals are feeding exclusively within residential areas where roses, flowers,
shrubs, and shady trees are grown and treated with triforine. The exceedance to mammals that
weigh 15 and 35 grams is based on the assumption that small and  medium sized mammals
occupy, exclusively and permanently, the area of registered uses, and foraging feed items with
triforine residues.  To the extent that those mammals do not reside exclusively and permanently
within the area, exposure will be less and risk is presumably less.  In addition, the RQs
calculated from average estimated environmental concentrations did not exceed LOCs.

Non-target insects

       Acute contact honeybee studies indicate that triforine is practically non-toxic to honey
bees(LD50>100|ig/bee).

Terrestrial Plants

       Open literature and approximately nine incidents reported  impacts to terrestrial plants
from the approved non-crop uses of triforine. Given the available information the potential risk
to non-target terrestrial plants cannot be precluded at this time and there are assumed to be
direct effects from triforine.  Additional data are required in order to assess the potential risk of
triforine to terrestrial plants.
IV.    Risk Management and Reregi strati on Decision

       A.     Determination of Reregi strati on Eligibility

       Section 4(g)(2)(A) of FIFRA calls for the Agency to determine, after submission of
relevant data concerning an active ingredient, whether or not products containing the active
ingredient are  eligible for reregi strati on.  The Agency has previously identified and required the
submission of the generic (i.e., active ingredient-specific) data required to support reregi strati on


                                                                                     20

-------
of products containing triforine as an active ingredient. The Agency has completed its review
of these generic data, and has determined that the data are sufficient to support reregi strati on of
all products containing triforine.

       The Agency has completed its assessment of the human health and ecological risks
associated with the use of pesticide products containing triforine. The Agency has determined
that triforine products are eligible for reregi strati on provided label amendments are made to
implement these mitigation measures, as outlined in Chapter V.  Appendix A summarizes the
uses of triforine that are eligible for reregi strati on.  Appendix B identifies the generic data that
the Agency reviewed as part of its determination of reregi strati on eligibility  of triforine, and
lists the submitted studies that the Agency found acceptable.  Data gaps are identified as generic
data requirements that have not been satisfied with acceptable data. Should  a registrant fail to
implement any of the reregistration requirements identified in this document, the Agency may
take regulatory action to address these concerns.

       B.     Requirements for Reregi strati on

       Triforine products are eligible for reregi strati on provided that registrants comply with
the requirements outlined in this document including the following: (1) submit required data
and (2) implement label changes.

              1.      Required Data

       Triforine products are eligible for reregi strati on provided that registrants submit data as
required by the product-specific data call-ins that EPA intends to issue as a result of this RED
(see Section V). The generic database supporting the reregi strati on of triforine uses has been
reviewed and determined to be adequate to support a reregi strati on eligibility decision, except
for data deficiencies in plant toxicity data. Additional plant toxicity data are required to better
characterize risk to non-target plants.

              2.      Risk Mitigation

       Products containing triforine are eligible for reregi strati on provided the specific labeling
requirements required in Table 9 are reflected on the triforine labels.

       C.     Regulatory Rationale

       The Agency has determined that triforine is eligible for reregi stration provided that  the
requirements for reregi strati on outlined in this document are  implemented. Provided that
registrants comply with the requirements of this RED, EPA believes that triforine will not
present risks inconsistent with FIFRA.

               1.    Human Health and Ecological Risk

       EPA has conducted human health and ecological risk assessments for triforine to
support the reregi strati on eligibility decision.  EPA concluded that there are  no outstanding
                                                                                       21

-------
human health risks due to the use of triforine as a pesticide product that are below the Agency's
level of concern.

       In EPA's ecological risk assessment, a number of exceedances were estimated from use
of triforine, specifically concerning chronic risk to mammals and birds, as well as potential risk
for plants. Although there are exceedances of the chronic LOG for birds and mammals, the
potential for risk is based on the assumption that birds and mammals are feeding exclusively
within residential areas where roses, flowers, shrubs, and shady trees are grown.   To the extent
that those birds and mammals do not reside exclusively and permanently within the area,
exposure will be less and risk is presumably less.

       Since there is currently no limit on the number of times triforine may be used in a year,
a statement will be added to all labels limiting the number of applications per year to 20 for all
triforine use sites.  The following statement is also required for all triforine labels in order to
reduce the opportunity for ecological exposure of triforine:

       "Do not apply directly to or near water, storm drains, gutters, sewers, or drainage ditches. Do
       not apply when windy. To prevent product run-off, do not over water the treated area(s) to the
       point of runoff or apply when raining or when rain is expected that day. Rinse application
       equipment over  lawn or garden area only."

Additional required label changes for triforine are included in Table 9.

              2.      Endocrine Screening

       EPA is required under the FFDCA, as amended by FQPA, to develop a screening
program to determine whether certain substances (including all pesticide active and other
ingredients) "may have an effect in humans that is similar to an effect produced by a naturally
occurring estrogen, or other such endocrine effects as the Administrator may designate."
Following the recommendations of its Endocrine Disrupter  Screening and Testing Advisory
Committee (EDSTAC), EPA determined that there were scientific bases for including, as part
of the program, androgen and thyroid hormone systems, in addition to the estrogen hormone
system. EPA also adopted EDSTAC's recommendation that the Program include evaluations
of potential effects in wildlife.  For pesticide chemicals, EPA will use FIFRA and, to the extend
that effects in wildlife  may help determine whether a substance may have an effect in humans,
FFDCA authority to require the wildlife evaluations. When the appropriate screening and/or
testing protocols being considered under the Agency's Endocrine Disrupter Screening Program
(EDSP) have been  developed and vetted, there may be additional screening and/or testing
required for the pesticidal use of triforine.

              3.      Endangered Species

       The Agency has developed the Endangered Species Protection Program to identify
pesticides whose use may cause adverse impacts on endangered  and threatened species and to
implement mitigation measures that address these impacts.  The  Endangered Species Act (ESA)
requires federal agencies to ensure that their actions are not likely to jeopardize listed species or
adversely modify designated critical habitat. To analyze the potential of registered pesticide
                                                                                     22

-------
uses that may affect any particular species, EPA uses basic toxicity and exposure data and
considers ecological parameters, pesticide use information, geographic relationship between
specific pesticide uses and species locations, and biological requirements and behavioral
aspects of the particular species. When conducted, these analyses take into consideration any
regulatory changes recommended in this RED being implemented at that time.

       The ecological assessment that EPA conducted for this RED does not, in itself,
constitute a determination as to whether specific species or critical habitat may be harmed by
the pesticide. Rather, this assessment serves as a screen to determine the need for any species-
specific assessment that will evaluate whether exposure may be at levels that could cause harm
to specific listed species and their critical habitat.  The species-specific assessment refines the
screening-level assessment to take into account information such as the geographic area of
pesticide use in relation to the listed species and the habits and habitat requirements of the listed
species.  If the Agency's specific assessments for the pesticidal use of triforine result in the
need to modify use of the pesticide, any geographically specific changes to the pesticide's
registration will be implemented through the process described in the Agency's Federal
Register Notice (54 FR 27984) regarding implementation of the Endangered Species Protection
Program.

       Risk findings are based solely on EPA's qualitative assessment for triforine and do not
constitute "may affect" findings under the ESA. A determination that there is a likelihood of
potential effects to a listed species may result in limitations on the use of the pesticide, other
measures to mitigate any potential effects, and/or consultations with the Fish and Wildlife
Service or National Marine Fisheries Service, as necessary. If the Agency determines use of
triforine "may affect" listed species or their designated critical habitat, EPA will employ the
provisions in the Services regulations (50 CFR Part 402).

V.     What Registrants Need to Do

       The Agency has determined that the products containing triforine (PC 107901) are
eligible for reregi strati on provided that the mitigation measures and label changes identified in
this RED are implemented. Registrants will need to amend their product labeling to incorporate
the label statements set forth in the Label Changes Summary Table 9.  The Agency intends to
issue a Data Call-In (DCI) requiring generic and product-specific data. Generally, the registrant
will have 90 days from receipt of a DCI to complete and submit response forms or request time
extensions and/or waivers with a full written justification. For product-specific data, the
registrant will have eight months to submit data and  amended labels.

       A.     Manufacturing Use Products

              1.     Additional Generic Data Requirements

       No fate data is required. However, ecological toxicity data for plants is required as
listed below.
                                                                                      23

Data Justification

       Data are not available to evaluate the risk of triforine to aquatic vascular plants (i.e.,
duckweed) or terrestrial plants. The potential impacts to these plants from exposure to triforine
are unknown. However, data from the open literature and a history of phytotoxicity incidents to
terrestrial vascular plants suggest that triforine may pose a risk to non-target aquatic vascular
and terrestrial plants.

       Due to the potential for surface run-off or spray drift, EPA has expanded the seedling
emergence and vegetative vigor data requirements to terrestrial food and feed crops, aquatic
food crops, and residential outdoor uses.  These factors trigger a data requirement for
submission of plant studies for the triforine.

       During the triforine RED process, the Agency has finalized its update to the data
requirements in 40 CFR part 158. These updated data requirements were promulgated on
October 26, 2007. Tier I seedling emergence, vegetative vigor, and aquatic vascular studies are
required for terrestrial and aquatic nonfood uses. These phytotoxicity data are needed to
evaluate the level of pesticide exposure to non-target terrestrial and aquatic plants and to assess
the impact of pesticides on endangered and threatened plants.

       A solid  understanding of the potential risks to terrestrial plants is essential for sound
environmental management because plants form the basis of most habitats and  significantly
contribute to  overall environmental quality. Without plant growth data for triforine, the Agency
cannot determine the levels of triforine that result in effects to terrestrial  and aquatic plants.

       The Agency now requires that seedling emergence and vegetative vigor studies be
conducted using the typical end use product (TEP).  The TEP that contains the  highest
percentage of active ingredient, and/or is the most commonly used, would be required. In
addition, the  Agency recommends the seedling emergence and vegetative vigor toxicity tests
include one of the ten lettuce cultivars (Avondefiance, Deciso, Kares, Lobjoits  cos, Plucos,
Vigar, All the Year Round, Romano, Valmaine or Winter Density) that may be susceptible to
triforine.

       Since EPA was unable to evaluate the potential risks to terrestrial plants in dry and
semi-aquatic  areas and aquatic vascular plants in water bodies associated with the proposed
uses of triforine, risks are presumed for terrestrial and aquatic vascular plants.  Data from Tier I
terrestrial and aquatic vascular plant toxicity studies will be used to estimate potential risks to
plants associated with uses of triforine. The data will reduce uncertainties associated with the
                                                                                       24

-------
current risk assessment for terrestrial and aquatic plants and will improve our understanding of
the potential effects of triforine on plants.

              2.     Labeling for Manufacturing-Use Products

       To ensure compliance with FIFRA, manufacturing-use product (MUP) labeling should
be revised to comply with all current EPA regulations, PR Notices, and applicable policies.
The MUP labeling should bear the labeling contained in Table 9.

       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 Registrant
must review previous data submissions to ensure that they meet current EPA acceptance criteria
and if not, commit to conduct new studies. If a registrant believes that previously submitted
data meet current testing standards, then the study MRID numbers should be cited according to
the instructions in the Requirement Status and Registrants Response Form provided for each
product.  The Agency intends to issue a separate product-specific data call-in (PDCI), outlining
specific data requirements.

              2.     Labeling for End-Use Products

       To be eligible for reregi strati on, labeling changes are necessary to implement measures
outlined in Section IV above.  Specific language to incorporate these changes is specified in
Table 9.  Generally, conditions for the distribution and sale of products bearing old
labels/labeling will be established when the label changes are approved.  However, specific
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.

       C.     Labeling Changes Summary Table

       In order to be eligible for reregi strati on, amend all product labels to comply with the
following table.  Table  9 describes how language on the labels should be amended.

Appendix B.  Table of Generic Data Requirements and Studies Used to Make the Reregi strati on
Decision

GUIDE TO APPENDIX B

       Appendix B contains a listing of data requirements which support the reregi strati on for
active ingredients within the 4-AP case covered by this RED.  It contains generic data
requirements that apply 4-AP in all products, including data requirements for which a "typical
formulation" is the test substance.

The data table is organized in the following formats:

   1.  Data requirement (Column 1).  The data requirements are listed in the order in which they
       appear in 40 CFR 158. The reference numbers accompanying each test refer to the test
       protocols set in the Pesticide Assessment Guidance, which is 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
       O. 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 is no MRID number has been assigned. Refer to the
Bibliography  appendix for a complete citation of the study.
