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 bromacil which
includes the active ingredients bromacil and its lithium salt. The enclosed Reregistration
Eligibility Decision (RED) contains the Agency's evaluation of the data base of these
chemicals, its conclusions of the potential human health and environmental risks of the current
product uses, and its decisions and conditions under which these uses and products will be
eligible for reregistration. The RED includes the data and labeling requirements for products
for reregistration. It may also include requirements for additional data (generic) on the active
ingredients to confirm the risk assessments.
To assist you with a proper response, read the enclosed document entitled "Summary
of Instructions for Responding to the RED". This summary also refers to other enclosed
documents which include further instructions. You must follow all instructions and submit
complete and timely responses. The first set of required responses are due 90 days from
the date of receipt of this letter. The second set of required responses are due 8 months
from the date of receipt of this letter. Complete and timely responses will avoid the Agency
taking the enforcement action of suspension against your products.
Please note that the Food Quality Protection Act of 1996 ("FQPA") became effective
on August 3, 1996, amending portions of both the pesticide law (FIFRA) and the food and
drug law (FFDCA). This RED takes into account the new safety standard set by FQPA for
establishing and reassessing tolerances. However, it should also be noted that in continuing to
make reregistration determinations during the early stages of FQPA implementation, EPA
recognizes that it will be necessary to make decisions relating to FQPA before the
implementation process is complete. In making these early case-by-case decisions, EPA does
not intend to set broad precedents for the application of FQPA. Rather, these early
determinations will be made on a case-by-case basis and will not bind EPA as it proceeds with
further policy development and any rulemaking that may be required.
-------
If EPA determines, as a result of this later implementation process, that any of the
determinations described in this RED are no longer appropriate, the Agency will pursue
whatever action may be appropriate, including but not limited to reconsideration of any
portion of this RED.
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 Jane
Mitchell (703) 308-8061. Address any questions on required generic data to the Special
Review and Reregistration Division representative Margaret Rice (703) 308-8039.
Sincerely yours,
Lois A. Rossi, Director
Special Review and
Reregistration Division

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, a DCI letter will be enclosed listing such requirements. If both generic and
product specific data are required, a combined Generic and Product Specific DCI letter will
be enclosed describing such data. However, if you are an end-use product registrant only and
have been granted a generic data exemption (GDE) by EPA, you are being sent only the
product specific response forms (2 forms) with the RED. Registrants responsible for generic
data are being sent response forms for both generic and product specific data requirements (4
forms). You must submit the appropriate response forms (following the instructions
provided) within 90 days of the receipt of this RED/DCI letter; 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 time extensions for product specific data
should be submitted in the 90-day response. Requests for data waivers must be submitted as
part of the 90-day response. 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, but are not
required to, 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

ABSTRACT
EPA has completed its reregi strati on eligibility decision regarding the pesticide bromacil,
case 0041, which includes the active ingredients bromacil and its lithium salt. This decision
includes a comprehensive reassessment of the required target data base supporting the use patterns
of currently registered products. This decision considered the requirements of the recently
enacted "Food Quality Protection Act of 1996" which amended the Federal Food Drug and
Cosmetic Act and the Federal Insecticide, Fungicide and Rodenticide Act, the two Federal statutes
that provide the framework for pesticide regulation in the United States. FQPA became effective
immediately upon signature and all reregistrarion eligibility decisions (REDs) signed subsequent
to August 3, 1996 are accordingly being evaluated under the new standards imposed by FQPA.
In establishing or reassessing tolerances, FQPA requires the Agency to consider aggregate
exposures to pesticide residues, including all anticipated dietary exposures and other exposures
for which there is reliable information, as well as the potential for cumulative effect from a
pesticide and other compounds with a common mechanism of toxicity. The Act further directs
EPA to consider the potential for increased susceptibly of infants and children to the toxic effects
of pesticide residue.
The Agency has reassessed bromacil food and feed tolerances under the standards of FQPA
and determined that, based on available information, there is a reasonable certainty that no harm
will result to infants and children or to the general population from aggregate exposure to
bromacil residues. EPA evaluated only dietary and drinking water exposure in the aggregate
assessment, since other non-occupational exposures to bromacil are unlikely. EPA has no
information to indicate that the toxic effects produced by bromacil would be cumulative with those
of any other compound, and therefore has considered only bromacil exposures in the aggregate
assessment.
In reaching the determination of safety for infants and children, the Agency found that the
toxicity data base for bromacil is complete, based on current requirements, and that the effects
observed in pre- and post-natal studies did not indicate any increased sensitivity of infants and
children to bromacil. Therefore, no additional uncertainty factor was used in the risk assessment.
Further, the Agency has determined that no revisions in tolerances will be required.
Sufficient data are available to ascertain the adequacy of the established tolerances listed for citrus
and pineapple fruit. No tolerances for residues of bromacil in milk, eggs, animal fat, meat and
meat byproducts are required because residues of bromacil expected in meat and milk would be
less than levels detected by the current analytical methods.
Bromacil is a broad-spectrum herbicide used for weed control in citrus and pineapple.
Both bromacil and its lithium salt are used for weed control in the following non-food uses:
drainage systems, outdoor industrial areas, rights-of-way/fence rows/hedge rows, paved areas,
non-agricultural uncultivated areas, and power stations. Recreational areas were considered
during the risk assessment but are not being supported. The Agency has concluded that all
xiii
-------
products registered for all uses are eligible for reregistration when labeled and used as specified
in the Reregistration Eligibility Decision.
To reduce potential risks of contamination to groundwater, and toxicity to pesticide
applicators, EPA is requiring, among other changes, reductions in the rate of application, use of
Personal Protective Equipment, and the establishment of Restricted Entry Intervals. In addition,
to reduce risks of acute and chronic effects to non-target plants and animals, EPA is requiring
reduced application rates and prohibiting certain aquatic applications. Additional ecological
effects studies are required to confirm or complete EPA's risk assessment and conclusions.
Before reregistering products containing bromacil, the Agency is requiring that product
specific data, revised Confidential Statement of Formula (CSF) and revised labeling be submitted
within eight months of the issuance of this document. These data include product chemistry and
acute toxicity testing. After reviewing these data and any revised labels and finding them
acceptable and in accordance with section 3(c)(5) of FIFRA, the Agency will reregister each
product.

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.
On August 3, 1996, the Food Quality Protection Act of 1996 (FQPA) (Public Law 104-
170) was signed into law. FQPA amends both the Federal Food, Drug, and Cosmetic Act
(FFDCA), 21 U.S.C. 301 et seq., and the Federal Insecticide, Fungicide, and Rodenticide Act
(FIFRA), 7 U.S.C. 136 et seq. The FQPA amendments went into effect immediately. As a
result, EPA is embarking on an intensive process, including consultation with registrants, States,
and other interested stakeholders, to make decisions on the new policies and procedures that will
be appropriate as a result of enactment of FQPA. This process will include a more in depth
analysis of the new safety standard and how it should be applied to both food and non-food
pesticide applications. The FQPA did not, however, amend any of the existing reregistration
deadlines in section 4 of FIFRA. The Agency will therefore continue its ongoing reregistration
program while it continues to determine how best to implement FQPA.
This document presents the Agency's decision regarding the reregistration eligibility of
the registered uses of bromacil and its lithium salt including the risk to infants and children for
any potential dietary, drinking water, dermal or oral exposures, and cumulative effects as
stipulated under the FQPA. The document consists of six sections. Section I is the introduction.
Section II describes bromacil and its lithium salt, 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 bromacil and its
lithium salt. Section V discusses the reregistration requirements for bromacil. 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.

'As of April 1996.
Bromacil was first registered in the United States for use as a herbicide in an end-use
product in 1961. The 95% technical formulation, DuPont Bromacil Technical, was registered in
1967. Products containing the dimethylamine and sodium salts of bromacil were registered in
1969. Products containing these salts are now canceled, and are not discussed further in this
document. A product containing the lithium salt of bromacil (Du Pont X-L Herbicide) was first
registered in 1970.
-------
A Registration Standard for bromacil was issued in September 1982 (NTIS PB87-110276).
The Registration Standard required the submission of product chemistry, residue chemistry,
toxicology, ecological effects and environmental fate studies. A Data Call-In (DCI) was issued
in September of 1991 for bromacil requiring additional product chemistry, residue chemistry,
toxicology, ecological effects and environmental fate studies. This RED reflects a reassessment
of all data which were submitted to support the reregistration of bromacil.
Additional controls have been placed on the use of bromacil by the state regulatory
agencies of Florida and California as a result of bromacil being detected in groundwater. Florida
prohibited the use of bromacil on vulnerable soils within one of its major citrus-growing areas,
the Central Ridge, by rule (Rule 5E-8.038 in volume 19, Number 44, November 5, 1993, page
6424, Florida Administrative Weekly).
California's State Management Plan for controlling the occurrence of pesticides in the
groundwater requires the use of Pesticide Management Zones (PMZs). California has set up
several bromacil-specific PMZs. A PMZ is a one square mile area that has been determined to
be vulnerable to ground water pollution. In these PMZs bromacil can only be applied to crops by
permit and in accordance with a ground water protection advisory. This advisory contains
specific information to reduce the potential for movement of the chemical into ground water.

Human Health Assessment

Hazard Assessment
The toxicological data base on bromacil is adequate to support reregistration eligibility.
The Agency believes bromacil and its lithium salt are toxicologically equivalent, therefore this
assessment applies to both active ingredients.
a. Acute Toxicity
The Agency has characterized the acute toxicity of technical grade bromacil based on
laboratory data. The following table summarizes the findings from acute toxicity studies
submitted to the Agency. Acute toxicity categories are assigned for each route of exposure and
range from IV (considered least toxic) to I (considered most acutely toxic). Data pertaining to the
acute eye and dermal irritation and dermal sensitization are not required to support the
reregistration of the technical grade active ingredient (TGAI), these data are presented for
informational purposes:

2 The lithium salt of bromacil falls into Toxicity Category II for eye irritation.
-------
The acute toxicity of bromacil by most routes of exposure has been categorized in the
lowest possible toxicity category, category IV. Only ocular exposure was in category III:
bromacil is mildly irritating to the eye. A dermal sensitization study in Guinea pigs (MRID
41304107) is currently in the review process, and a detailed review will be issued at a later date.
b. Subchronic Toxicity
A 90-day subchronic feeding study is not available but is not being required since the
existing chronic data adequately characterize risk associated with subchronic duration of exposure.
c. Chronic Toxicity and Carcinogenicity
In a chronic toxicity study, Beagle dogs were given 0, 25, 150, or 625 ppm bromacil in
the feed for one year. Body-weight gains were decreased in both sexes at 625 ppm. Although
testicular atrophy and degeneration were observed in males at all dose levels, these effects were
determined to be unrelated to treatment based on (1) the lack of a dose response for the unilateral,
the bilateral, and the combined unilateral/ bilateral lesions and (2) the lack of an increase in the
incidence or severity with a 25-fold increase in dose. The NOEL was 150 ppm (4.65 o"/4.6 ¥
mg/kg/day). The LOEL was 625 ppm (17.8 cf/17.3 ? mg/kg/day), based on decreased body-
weight gains (MRID 41869701).
A combined chronic toxicity and carcinogenicity study was conducted with Crl:CD (BR)
rats. The doses given in the diet for two years were 0, 50, 250, or 2500 ppm. The NOEL was
250 ppm [9.82 cT/13.3 ¥ mg/kg/day]. The LOEL was 2500 ppm (103d-/144? mg/kg/day), based
on decreased body-weight gains. Additional effects observed were (1) increased incidence in the
high-dose males of cystic follicles and ultimo branchial cysts of the thyroid, hyperplasia and clear
cell foci of the adrenal cortex, and retinal atrophy; (2) increased incidence of epithelial hyperplasia
of the thymus in the high-dose females; and (3) dose-related increasing trends in thyroid C-cell
adenomas and thyroid follicular cell adenomas and/or carcinomas combined in the males (MRID
41261701).
In a carcinogenicity study, CD-I mice were given bromacil in the diet for 18 months. The
doses were 0, 250, 1250, or 5000 ppm bromacil in the diet (0, 40, 196, or 871 mg/kg/day for
males; 0, 67, 330, or 1131 mg/kg/day for females). The NOEL for systemic effects was not
determined, based on liver lesions at all dose levels in males. The systemic LOEL was 40
mg/kg/day, based on the following liver effects: increased incidence in hepatocellular
hypertrophy, single cell and centrilobular necrosis, hepatocellular lysis with RBC accumulation,
and centrilobular vacuolation. There was a significant increase in combined hepatocellular
adenomas and/or carcinomas at 871 mg/kg/day in males only, and there was a significant dose-
related trend for hepatocellular carcinoma and for combined hepatocellular adenomas and/or
carcinoma in males (MRID 00072782).
-------
d. Developmental Toxicity
A developmental toxicity study with Crl:CD BR rats used doses of 0, 20, 75, 200, or 500
mg/kg/day given by gavage on gestation days 7-16. The maternal toxicity NOEL was 20
mg/kg/day. The maternal toxicity LOEL was 75 mg/kg/day, based on decreased body-weight gain
and decreased food consumption during the first two days of dosing. The developmental toxicity
NOEL was 75 mg/kg/day. The developmental toxicity LOEL was 200 mg/kg/day, based on
increased incidence of rudimentary lumbar ribs and extra thoracic vertebrae. Significant increases
in skeletal developmental variations due to retarded development; i.e., retarded or partial
ossification of the axial skeleton [interparietal, parietal, and supraoccipital skull bones, bipartite
and dumbbelled centrum of the vertebrae, sternum and hyoid] and the partial ossification of the
appendicular skeleton [pubis and ischium] were observed at the highest dose tested (MRID
40984802).
In a developmental toxicity study in Hra:(NZW)SPF rabbits, doses of 0, 30, 100, 300,
or 500 mg/kg/day were given by gavage on gestation days 7-19. The NOEL for maternal toxicity
was 100 mg/kg/day. The LOEL for maternal toxicity was 300 mg/kg/day, based on decreased
body-weight gain and food consumption. There were no effects on maternal reproductive
parameters. The NOEL for developmental toxicity was 100 mg/kg/day. The LOEL for
developmental toxicity was 300 mg/kg/day, based on the increase in the percentage of late post-
implantation loss. There was a significant reduction in the number of female pups at the 300 and
500 mg/kg/day dose levels, and there was a significant increase in the mean percentage of skeletal
variations at the highest dose level (MRID 40984801). The Agency does not consider bromacil
to be a developmental toxicant.
e. Reproductive Toxicity
In a two generation reproduction study, Crl:CD BR rats were fed doses of 0, 50, 250, or
2500 ppm bromacil. No effects on reproductive performance were seen. The parental NOEL was
250 ppm (12.5 mg/kg/day). The LOEL was 2500 ppm (125 mg/kg/day), based on significantly
increased incidence of hydronephrosis. The reproductive NOEL was > 125 mg/kg/day (MRID
41804601).
f. Mutagenicity
Bromacil did not induce a mutagenic response in the Ames assay, with and without
activation (MRID 42465701). In an in vivo micronucleus assay in mice, bromacil was negative
(MRID 42465801). Bromacil was not genotoxic in the unscheduled DNA synthesis assay (MRID
42465901). The Agency does not consider bromacil to be mutagenic.
Additional data submitted under section 6(a)(2) of FIFRA by E.I. DuPont de Nemours
and Company has received a cursory review (MRID 44005401 and 02) by the Agency. This
submission is currently in the review process and a detailed review will be issued at a later date.
10
-------
The Registrant is required to submit all the full mutagenicity studies addressed in MRID
44005401. A summary of the Registrant's analysis follows.
Krovar® DF is formulated from 40% bromacil, 40% diuron and 20% inert ingredients.
Krovar® DF was evaluated in an in vivo mouse micronucleus mutagenicity assay and was found
to be positive for clastogenic activity (study not submitted).
Subsequently, bromacil was tested in an in vitro chromosome abberrations mutagencicity
assay in human lymphocytes and was found to be positive for clastogenic activity (MRID
44005402).
Bromacil was also tested in an in vivo micronucleus assay and was found to be negative
for clastogenic activity (study not submitted).
In addition, diuron technical (98%) was tested in male and female rat bone marrow cells
following single oral doses of 50, 500, and 5000 mg/kg by oral intubation. Signs of systemic
toxicity and body weight loss were observed in the rats at the 5000 mg/kg level. Diuron was
considered positive for clastogenic activity (study not submitted).
The Agency's Mutagenicity Risk Assessment Guidelines give more weight to in vitro test
results. The evidence presented by the registrant indicates that the positive mutagenicity of
Krovar® DF is most likely due to the diuron and not the bromacil.
The weight of evidence suggests that bromacil is not mutagenic. This is supported by the
studies addressed in the first paragraph of this section. Agency does not consider bromacil to be
mutagenic.
g. Metabolism
Metabolic studies were conducted with rats given single [low and high] and multiple [low]
doses of radiolabelled bromacil. The major route of elimination was via the urine following all
dosing schedules except the multiple low dose in males where urine and fecal elimination were
approximately equal. Bromacil was absorbed readily from the gastrointestinal tract, extensively
metabolized [primarily by hydroxylation at the 6-methyl position and on the sec-butyl moiety],
and rapidly excreted. The hydroxylated metabolites were eliminated as glucuronide conjugates.
Radiolabel was found in all tissues examined, but there was no evidence of accumulation. The
major metabolite of bromacil in the urine of rats was 5-bromo-6-hydroxymethyl-3-sec-butyl-
uracil. Trace levels of the parent compound and two other (unidentified) metabolites were
excreted in the urine (MRID 42825201).
h. Dermal Absorption
The Agency established an interim estimate of 20% dermal absorption for bromacil using
a non-guideline absorption study and surrogate data from other pesticides. A discussion of these
11
-------
data and the Agency's rationale follow. The registrant, in a document entitled Detailed Risk
Mitigation Proposals for Bromacil Reregistration, cites a 1965 skin absorption study in rabbits
and, using several conservative assumptions, estimates dermal absorption of bromacil during a
workday (8 hours) to be 4.6%. In addition, a preliminary literature search for in vitro human
absorption values suggests 14% absorption of 5-fluorouracil, a surrogate substituted uracil. On
this basis the registrant has suggested using an interim 20% absorption value in the worker risk
assessment while they conduct a 28-day dermal toxicity study in rats.
Using data/information on other pesticides for which there are dermal absorption data
whose solubilities are similar to bromacil, and given that bromacil is neither volatile nor a dermal
irritant, the Agency can reasonably assume dermal absorption of these materials to be similar.
For example, maneb, is a solid, as is bromacil and has a molecular weight and solubility similar
to that of bromacil. Dermal penetration of maneb is expected to be no greater than one percent.
For these reasons, the Agency believes the interim estimate of 20% absorption of bromacil is
reasonable.
2. Dose-Response Assessment
a. Reference Dose
The Agency determined the RfD for bromacil to be 0.1 mg/kg/day, based on the NOEL
of 9.82 mg/kg/day in the chronic rat toxicity study. An uncertainty factor of 100 was used to
account for the inter-species extrapolation and intra-species variability (Ghali, 1994). The World
Health Organization/Joint Meeting on Pesticide Residues has not evaluated bromacil.
b. Cancer Classification
The Office of Pesticide Programs Carcinogenicity Peer Review Committee classified
bromacil as Group C - possible human carcinogen - and recommended that the Reference Dose
(RfD) approach be used for quantification of human risk. This decision was based on the increased
incidence of liver tumors in male mice, and positive trends in thyroid tumors in male rats, and
to a lesser extent on analysis of structural activity relationship to similar compounds. Bromacil
is not considered mutagenic.
c. Toxicity Endpoints
Based upon its review of the toxicology data base for bromacil, the Agency selected a
toxicological endpoint and dose level of concern appropriate for risk assessment (Toxicology
Endpoint Selection Document, November 15, 1994). This endpoint is maternal toxicity, from the
rat developmental toxicity study (MRID 41804601) described above. Short- (1 to 7 days) and
intermediate- (1 week to several months) term occupational risk assessments are appropriate, due
to the low NOEL and the lack of a 21-day dermal toxicity study. An acute dietary risk assessment
is not appropriate, because the effects noted in the above study would not be expected with just
12
-------
one dose. Also, there was no evidence to indicate that bromacil was associated with major
developmental or reproductive toxicity.
The Agency selected this endpoint for the following reason. In the developmental toxicity
study in rats, bromacil was tested at 0, 20, 75, 200, and 500 mg/kg/day. The maternal NOEL
was 20 mg/kg/day, the maternal LOEL was 75 mg/kg/day based on a decrease in body weight
and food consumption during the dosing period. A significant increase in liver weight at 500
mg/kg/day was observed. The developmental NOEL was 75 mg/kg/day, and the developmental
toxicity LOEL was 200 mg/kg/day, based on an increased incidence of rudimentary lumbar ribs
and an extra thoracic vertebra.
The LOEL at 75 mg/kg/day is an indication of maternal stress. The maternal effect noted
was a minimal effect involving decreases in body weight gain and food consumption during only
the first two days of dosing. Thus, the actual maternal NOEL level is likely to be considerably
higher than 20 mg/kg/day.
3. Exposure Assessment
This section describes the process the Agency used to estimate human exposure to bromacil
from the diet and from occupational use.
a. Dietary Exposure
A dietary risk assessment is required when a chemical is registered for use on crops used
either as food for people or feed for livestock. Bromacil meets this criteria. It is registered for
food/feed use on citrus and pineapple. Formulations may be applied as soil broadcast or banded
sprays to citrus or pineapple and broadcast foliar applications to pineapples using ground
equipment. The bromacil lithium salt is not registered for use on any crops.
The residue chemistry data base identifying and quantifying the residues of bromacil is
adequate and supports reregistration of bromacil as a food use pesticide on citrus and pineapple.
Tolerances for residues of bromacil at 0.1 ppm in/on citrus and pineapples have been established
and are expressed in terms of bromacil per se [Source: 40 CFR §180.210]. No tolerances exist
for residues of bromacil in animal commodities; and no food/feed additive tolerances have been
established.
Directions for Use on Citrus and Pineapples
Three end-use products (EPs) of bromacil are presently registered to E.I. du Pont de
Nemours & Co. that may be used on food/feed crops grown in the U.S. The bromacil EPs are
presented below:

2 Multiple active ingredient product.
All registered formulations of bromacil prohibit their application through any type of
irrigation system. The 80% WP, and the 40% DF specify a 12-hour reentry interval. A reentry
interval is not specified for the 80% DF. Preharvest intervals are not specified in any of the
labels.
The 40%, 53%, and 80% WP and DF bromacil formulations are registered for band or
broadcast ground treatment beneath and/or between established bearing citrus trees at 1.1-6.4 Ib
ai/A/application or 0.8-3.2 Ib ai/A/application as split treatments; the 53% WP may also be used
in FL as a split application at up to 4.2 Ib ai/A/application. Spray applications must be made in
a minimum of 40 gal of water/A. The application rates are dependent on soil types; higher rates
are recommended for silt loam or clay loam soils and lower rates are recommended for sand or
loamy sand soils. The maximum seasonal use rate for citrus varies among labels and depends
upon location, soil conditions, and orchard age. For established bearing trees (>4 years), all
labels (except the 53% WP) specify a maximum seasonal rate in FL of 6.4 Ib ai/A/year on soils
of low permeability and 4.2 Ib ai/A/year on highly permeable soils; the 53% WP allows a
maximum seasonal rate in FL of 8.5 Ib ai/A/year. For other citrus producing regions
(AZ/CA/LA/TX), the 80% WP and DF and the 53% DF labels do not specify a maximum
seasonal use rate, the 53 WP specifies a maximum of 5.3 Ib ai/A/year, and the 40% WP and DF
formulations specify maximum use rates of 6.4 Ib ai/A/year for TX and LA and 2.4 Ib ai/A/year
for CA and AZ. The maximum seasonal use rates on citrus for specific regions and conditions
must be standardized between the labels.
All labels specify that grazing of cattle in treated areas is prohibited. Treated areas may
be planted to citrus trees one year after the last application. Replanting of treated areas to any
crop other than citrus within two years after application is prohibited. The 53% C and 80% WP
and DF formulation labels also prohibit applications to citrus in Kern County, CA because of the
threat to groundwater.
The 80% WP and the 80% DF are registered for multiple applications to pineapples grown
in HI and FL. The first treatment may be made at 1.6-4.8 Ib ai/A as a ground broadcast
application before plants begin to grow. The remaining treatments may be made either as directed
interline applications prior to floral differentiation at 1.6-3.2 Ib ai/A or as broadcast treatments
14
-------
at 1.6 Ib ai/A after the plant is 8 months old but prior to floral differentiation. The formulations
are also registered for application to ratoon crops at 0.8-3.2 Ib ai/A to be applied using ground
equipment after harvesting the planting crop but before differentiation. The maximum seasonal
application rates are 8 Ib ai/A and 3.2 Ib ai/A to the planting and ratoon crops, respectively. In
Puerto Rico, bromacil is registered for use on pineapples at 0.8-3.2 Ib ai/A to be applied
immediately after planting and before plants begin to grow. Replanting of treated areas to any
crop other than pineapples within two years after application is prohibited.
Plant Metabolism
The qualitative nature of the residue in plants is adequately understood based on acceptable
orange and pineapple metabolism studies. Results from the orange metabolism study indicate that
bromacil undergoes hydroxylation at the 6-methyl group to produce Metabolite A (5-bromo-3-sec-
butyl-6-hydroxy-methyluracil), which is readily conjugated with glucose and is converted to a
malonyl ester of glucose conjugate of Metabolite A. In pineapple the metabolism of bromacil
proceeds from hydroxylation of the sec-butyl side chain followed by conjugation of the
hydroxylated metabolites. The residue of concern and the residue to be regulated in citrus and
pineapple fruit is bromacil perse (MRIDs 13202, 002415, 014750, 42967501, 43460601)
Animal Metabolism
The nature of the residue in animals is adequately understood based on an acceptable
ruminant metabolism study reflecting oral dosing. In ruminants, bromacil is hydroxylated at the
6-methyl and the sec-butyl side chains and the 6-hydroxymethyl derivative is further conjugated.
A poultry metabolism study is presently not required since bromacil is not registered for use on
crops that are used as poultry feed (MRIDs 002192, 42998901).
Residue Analytical Methods - Plants and Animals
Adequate methods are available for tolerance enforcement and data collection. A GLC
method with microcoulometric detection is available for tolerance enforcement and is listed in
Pesticide Analytical Method (PAM) Vol. II as Method I. Additional methods include a GLC
method with electron-capture detection (ECD), published in PAM Vol. II as Method B, and an
improved GLC method using a thermionic nitrogen/phosphorus detector (GLC/ECD) used for
data collection. These methods have not undergone validation by the Agency (MRID 013999,
014217, 019944, 42967301, 43078801).
The registrant submitted data on a GLC/ECD method for determining residues of bromacil
per se in/on oranges and pineapple. The submitted method is a modification of Method B
published in PAM Vol. II and has a more sensitive limit of detection (LOD = 0.01 ppm) than any
of the enforcement methods. In addition, the registrant has submitted data on a confirmatory
GLC/MSD data collection method for citrus and pineapple that may be used if bromacil residues
are present at or above a level of 0.01 ppm.
15
-------
Enforcement analytical methods for residues in animals are not required as no tolerances
exist for bromacil in animal commodities.
The FDA PESTDATA data base dated 1/94 (PAM Vol. I, Appendix II) indicates that
bromacil is completely recovered (> 80%) using PAM, Vol. I Multiresidue Protocol D and not
recovered using Protocol E Sections 211.1 or 212.1.
Storage Stability
The requirements for storage stability data are satisfied for the purposes of reregistration.
The submitted storage stability data indicate that residues of bromacil per se are stable at -15 C
for up to 18 months in citrus and pineapple fruits and in pineapple beverage juice and bran at <15
C for 99 and 139 days, respectively.
The registrant did not provide information regarding the duration of storage of citrus
samples that were used for tolerance assessment. However, since residues of bromacil were not
observed in the citrus metabolism study and residue samples used for tolerance assessment bore
nondetectable (< 0.05 ppm) residues of bromacil per se, it can be concluded that the citrus fruit
field trials are validated by acceptable storage stability data (MRID 42967401, 43461601).
Magnitude of the Residue in Plants
The reregistration requirements for magnitude of the residue in plants using bromacil are
fulfilled. Adequate field trial data depicting residues of bromacil following applications made
according to the maximum registered use patterns have been submitted for citrus and pineapple.
Geographical representation is adequate and a sufficient number of trials reflecting representative
formulation classes were conducted.
Citrus Fruits Group
Oranges, Lemons, Grapefruit, and Tangelos: The Agency concluded that acceptable data on
citrus (oranges, lemons, grapefruit, and tangelos) are available. Residues of bromacil perse were
< 0.05 ppm in/on citrus harvested up to 8 months after treatment with 3.2-8.0 Ibs ai/A/season of
bromacil in tests performed in CA, TX, and FL. Also, additional data on citrus were submitted
in support of an amended use to increase the maximum seasonal use rate from 6.4 Ib ai/A/season
to 8.5 Ib ai/A/season in FL. Residues of bromacil per se were < 0.05 ppm in/on citrus harvested
7, 14, 21, and 28 days after the last treatment with 6.4-8.5 Ib ai/A/season of bromacil in 4 tests
performed in FL. The available data support the established 0.1 ppm crop group tolerance for
residues of bromacil in/on citrus fruits (MRID 13203, 13206, 13321, 30632, 50468, 137865).
Miscellaneous Commodities
Pineapple: Recently submitted field data from three tests in HI indicate that residues of
bromacil will not exceed the established tolerance of 0.1 ppm in/on pineapples harvested 125-215
16
-------
days following the last of two applications of the bromacil 80% WP formulation at 10 Ib ai/A
(1.25x the maximum seasonal rate) or 20 Ib ai/A (2.5x). Residues of bromacil per se were
nondetectable (< 0.04 ppm) in/on five control samples and seven treated samples. No additional
data are required; however, the registrant must specify a PHI in all relevant labels. As pineapple
forage is no longer listed as a regulated commodity in the updated (9/95) Table II of Subdivision
O, Residue Chemistry, data in/on pineapple forage are no longer required (MRID 13205,13293,
43461601).
Magnitude of the Residue in Processed Food/Feed
The reregistration requirements for magnitude of the residue in processed food/feed
commodities are fulfilled for citrus and pineapple. A summary of the available data and
reregistration status is presented below for each commodity.
Citrus Fruits: Acceptable data on citrus processed commodities are available. Residues of
bromacil per se were < 0.04 ppm in/on citrus dried pulp. Data for citrus molasses were not
submitted but the Agency concluded that if residues do occur in dried citrus pulp and molasses
they will not exceed the tolerance for the raw agricultural commodity. Also, additional data on
citrus processed commodities were submitted in support of an amended use to increase the
maximum seasonal use rate of bromacil in FL. Residues of bromacil in orange fruit, peel, pulp,
and juice were nondetectable (< 0.05 ppm). Residues do not concentrate in any citrus processed
commodities. No food/feed additive tolerances are required for the processed commodities of
citrus (MRID 13203, 13206, 13321, 30632, 137865).
In a pineapple processing study (MRID 43461601), residues of bromacil were
nondetectable (< 0.04 ppm) in/on pineapple harvested 215 days after two broadcast applications
of bromacil (80% WP), first at 12 Ib ai/A before planting followed by a second application prior
to floral induction at 8 Ib ai/A for a total seasonal rate of 20 Ib ai/A (2.5x). Residues were also
nondetectable in/on juice and bran processed from the pineapples. Although the pineapple fruit
used to obtain processing data did not bear measurable residues, the Agency concluded that the
pineapple processing study is adequate because the registrant indicated that the plants treated at
2.5x exhibited signs of phytotoxicity. No food/feed additive tolerances are required for pineapple
juice or bran.
Magnitude of the Residue in Meat, Milk, Poultry, and Eggs
There are no established tolerances for bromacil residues in eggs, milk, animal fat, meat,
and meat by-products. A 1970 study reported residues of bromacil per se of <0.116 ppm in milk
from a dairy cow fed bromacil at 30 ppm in the diet (MRID 05002192).
The Agency has concluded that ruminant feeding studies and animal tolerances are not
required because residues of bromacil expected in milk and meat would be < 0.0001 ppm, a level
that would not be detected by the current analytical methods. This conclusion is based on I) a
maximum theoretical dietary burden of 0.033 ppm for cattle calculated by assuming 33% of the
17
-------
diet consisting of dried citrus pulp, ii) the level of bromacil fed to the animals in the ruminant
metabolism study (9.2 ppm; 280x); and iii) the low TRR levels in milk (0.04 ppm) and tissue
samples (0.02 ppm) from the metabolism study.
In addition, because no poultry feed items presently have tolerances for bromacil,
conventional feeding studies are not required for poultry and no tolerances are required for poultry
meat and eggs.
Confined Rotational Crops
Pineapple and citrus crops are normally not rotated, therefore, the requirement for
confined rotational crop studies does not apply.
Summary of Residue Chemistry Assessment
Adequate plant metabolism and magnitude of the residue data are available for citrus and
pineapple. Adequate processing studies have been submitted and residues of bromacil do not
concentrate in processed commodities of citrus and pineapple. The qualitative nature of the
residue in ruminants is adequately understood and data on nature of the residue in poultry are not
required because no poultry feed items presently have tolerances for bromacil. Livestock feeding
studies and animal tolerances are not required. In addition, the Agency has FDA's surveillance
monitoring data (FY78-FY88) and Total Diet Study data (1982-1986). Therefore, a reliable risk
assessment for the uses of bromacil can be conducted.
The compound 5-bromo-3-(2-hydroxy-l-methylpropyl)-6-methyluracil (Metabolite D)
comprises a significant portion of the residue in pineapples. It was observed at a level 12 times
that of the bromacil concentration in pineapple fruit. Therefore, while the residue to be included
in the tolerance expression for pineapples will be bromacil, the Agency will use a 12X factor for
the risk assessment. In the crop field trials no bromacil was observed at a limit of quantification
of 0.04 ppm; therefore, the exposure which will be used will be 0.5 ppm. The present tolerances
use up only ca. 1% of the new RfD for bromacil. Therefore, significantly less than 100% RfD
will be taken up even when this additional residue is incorporated into the risk assessment.
b. Occupational Exposure
An occupational exposure assessment is required for an active ingredient if (1) certain
toxicological criteria are triggered and (2) there is potential exposure to handlers (mixers, loaders,
applicators) during use or to persons entering treated sites after application is complete. Bromacil
meets these criteria.
18
-------
Handler (Mixer/Loader/Applicators) Exposures
There is potential exposure to mixers, loaders, applicators, or other handlers during usual
use-patterns associated with bromacil. Eight major exposure scenarios were identified for
bromacil:
(1) mixing/loading the liquid flowable, wettable powder, or dry flowable formulations for
groundboom or aerial application;
(2) applying as a spray with power sprayer equipment to treat rights-of-ways and under
toxic-waste holding-pond liners;
(3) applying as a spray with groundboom equipment;
(4) applying using aerial fixed wing aircraft;
(5) applying using aerial helicopter;
(6) mixing/loading and applying with a low pressure handwand;
(7) mixing/loading and applying with a push-type spreader; and
(8) mixing/loading and applying granulars with a whirly bird spreader.
(9) mixing/loading and applying with a backpack/knapsack sprayer.
For these nine bromacil handler exposure scenarios, the Agency used the Vl.l version of
the Pesticide Handler's Exposure Data Base (PHED) except for the low pressure handwand
scenario version where version VI.01 was used. Table 7 includes the equipment used for each
exposure scenario and the daily treatment area. In addition, application is permitted using shaker
or sprinkler cans and by aerosol, but no assessment was performed on these application methods.
Exposure from these methods is expected to be less than for the above scenarios because the total
amount of bromacil applied would be considerably less using these methods than the above
methods.
The Agency used the same exposure values identified for rights-of-way spray applications
for the toxic-waste holding-pond applications, except the maximum treatment area for the holding-
ponds is assumed to be nearly five times that for rights-of-ways applications. A tractor drawn
solid broadcast application has been identified for a pelleted formulation. The Agency is using
the groundboom spray application exposure (and liquid mixer/loader exposure) as the worst case
scenario for the pelleted use in absence of pelleted exposure data. All further risk characterization
and PPE requirements for the tractor drawn mixer/loader/applicator are based on the mixing,
loading, and application of the groundboom spray scenario. The Agency expects the estimated
exposures for groundboom spray to overestimate any exposure that might result from applying
the pelleted formulation.
Post-Application Exposure
Post-application exposure is likely since bromacil is broadcast in pineapple plantations and
citrus orchards. However, exposure is expected to be relatively low since bromacil is generally
directed at the target weeds therefore contact with treated surfaces is likely to be limited mostly
to feet, lower legs, and, in some circumstances, hands. For these reasons, post-application
19
-------
exposure data are not required for brush and weed control in crop areas, right-of-ways, paved
areas, non-agricultural uncultivated areas, power stations, recreational areas, and orchard floors.
4. Risk Characterization
a. Dietary Risk
Acute Dietary Risk
An acute dietary risk assessment is not required because acutely toxic effects are not
expected at concentrations of bromacil which are likely to be found in food (see Dose-Response
Assessment section).
Chronic Dietary Risk
Residue Information
Tolerances for bromacil are published in 40 CFR §180.210. Tolerances had been
established in/on citrus and pineapples at 0.1 ppm. The available data support the established
tolerances and there are no suggested revocations or amendments to existing tolerances.
Tolerance level residues and 100 percent crop treated assumptions were made for all commodities.
No anticipated residue (AR) information was used in this analysis. No tolerances exist for
residues of bromacil in animal commodities and no food/feed additive tolerances have been
established and none are needed.
Results
A DRES chronic exposure analysis was performed using tolerance level residues and 100
percent crop treated information to estimate the TMRC for the general population and 22
subgroups.
Existing tolerances result in a TMRC which represents < 1% of the RfD for the U.S.
general population. The highest subgroup, children 1-6 years old occupies 1% of the RfD.
The analysis for bromacil is a worst case estimate of dietary exposure with all residues at
tolerance level and 100 percent of the commodities assumed to be treated with bromacil. Based
on the risk estimates calculated in this analysis, it appears that chronic dietary risk, including
cancer, from the uses recommended through reregistration, is not of concern.
b. Occupational Risk
The exposure scenarios are presented in the following tables along with the corresponding
exposure/risk assessment. The baseline dermal unit exposures for all handlers represents the
current label requirements: scenarios la, Ib, Ic, Id, and 3 are based on single layer clothing and
chemical resistant gloves while using open pour and open cockpit/cab; scenarios 2a, 2b, 4, 5, 6,
7, and 8 are based on single layer clothing and no gloves (baseline also represent the registrant's
20
-------
proposed rate reduction from 24 Ib ai/acre to 12 Ib ai/acre). The additional PPE (Table 4:
scenarios 2a, 2b, 4, 6 and 8) represents dermal unit exposures when chemical resistant gloves are
worn. The risk mitigation for scenario Ib (mixing/loading wettable powder formulations) is water
soluble packets and single layer clothing and no gloves.
Margins of exposure (MOEs) were calculated using the following formula:
*,^r NOEL 20MG/KG/DAY
MOE= =
EXPOSURE DailyDermalExposure(mglkglday)
Risk to Handlers (Mixers, Loaders, Applicators, etc.)
Bromacil has the potential for significant exposure to mixer/loaders and applicators. From
a review of the labels, the Agency identified nine possible handler exposure scenarios.
With the addition of chemical-resistant gloves or, in one instance, engineering controls,
all exposure scenarios (except the toxic-waste holding-pond scenario at the maximum acreage, the
mixing/loading for aerial application, and the mixing/loading dry flowables for groundboom at
the maximum application rate of 25 Ib ai/A) resulted in MOEs greater than or equal to 100 (see
Table 9). For the toxic-waste holding-pond scenario at the maximum acreage (48 acres), the
MOE is less than 100 (see Table 8) even when the applicator is wearing chemical-resistant gloves.
For this scenario, the Agency assumes that five acres is an area typically treated for this
treatment and believes areas as large as 48 acres are treated only occasionally based on
information provided by the registrant.
The mixing/loading of dry flowables and wettable powders resulted in MOEs less than
100. However, these MOEs are based upon a developmental toxicity study in rats in which the
maternal NOEL was established at 20 mg/kg/day and the maternal LOEL at 75 mg/kg/day. The
maternal effect noted was a minimal effect involving decreases in body weight gain and food
consumption during only the first two days of dosing. Thus, the actual maternal NOEL level is
likely to be considerably higher than 20 mg/kg/day. In addition, both the maternal and
developmental NOELs in the rabbit study were established at a higher dose level, 100 mg/kg/day.
Consideration of the minimal, transitory effects noted at the rat maternal LOEL (75 mg/kg/day)
and the much higher dosage (200 mg/kg/day) required to elicit pronounced developmental effects,
leads to a conclusion that the actual MOEs for these scenarios is at least 100.

Risk From Post-Application Exposures
No post-application exposure data are available for bromacil. EPA believes that the post-
application exposures are likely, particularly following applications to citrus, pineapples, and
recreation areas. These exposures may occur during activities, such as mowing and scouting in
citrus orchards, scouting in pineapple plantations, and recreational activities in recreation areas.
Since bromacil is generally directed at the target weeds, contact with treated surfaces is likely to
be limited mostly to feet, lower legs, and, in some circumstances, hands.
c. Food Quality Protection Act Considerations
The Food Quality Protection Act of 1996 (FQPA) amended the FFDCA by setting a new
safety standard for the establishment of tolerances. In determining whether a tolerance meets the
new safety standard, section 408(b)(2)(C) directs EPA to consider information concerning the
susceptibility of infants and children to pesticide residues in food, and available information
concerning aggregate exposure to infants and children of such residues, as well as the potential
for cumulative effects from pesticide residues and other substances that have a common
mechanism of toxicity.
The FQPA amendments to section 408 (b) (2) (C) require EPA to apply an additional 10-fold
uncertainty (safety) factor unless reliable data demonstrate that the additional factor is
unnecessary to protect infants and children.
Section 408 (b) (2) (D) establishes factors that the Agency must consider in determining
whether the safety standard is met in deciding to issue or reassess tolerances. These factors
include the consideration of available information on the aggregate exposures to the pesticide from
dietary sources including drinking water as well as non-occupational exposures such as those
derived from pesticides used in and around the home. The Agency must also consider the
potential cumulative effects of the pesticide for which a tolerance is being sought as well as other
substances that have a common mechanism of toxicity.
Because bromacil has food uses, specific consideration of the risks to infants and children,
as well as aggregate exposures and potential cumulative effects is warranted.
Potential Risk to Infants and Children
In determining whether a safety factor different than the additional 10-fold is or is not
appropriate for assessing risks to infants and children, EPA considers all reliable data and makes
a decision using a weight of evidence approach taking into account the completeness and adequacy
of the toxicity data base, the nature of the effects observed in pre and post-natal studies, and other
information such as epidemiological data.
For the purpose of assessing the pre- and post-natal toxicity of bromacil, EPA has
evaluated two developmental and one reproduction study. Based on current data requirements,
these three studies when considered along with other required toxicity studies, constitute a
24
-------
complete data base for evaluating pre- and post-natal effects for food use chemicals. However,
as EPA fully implements the requirements of FQPA, additional data related to the special
sensitivity of young organisms may be required.
Developmental and Reproductive Effects
The effects observed in the bromacil developmental and reproduction studies can be
summarized as follows:
A developmental toxicity study with Crl:CD BR rats used doses of 0, 20, 75, 200, or 500
mg/kg/day given by gavage on gestation days 7-16. The maternal toxicity NOEL was 20
mg/kg/day. The maternal toxicity LOEL was 75 mg/kg/day, based on decreased body-weight gain
and decreased food consumption during the first two days of dosing. The developmental toxicity
NOEL was 75 mg/kg/day. The developmental toxicity LOEL was 200 mg/kg/day, based on
increased incidence of rudimentary lumbar ribs and an extra thoracic vertebra. Significant
increases in skeletal developmental variations due to retarded development, i.e., retarded or
partial ossification of the axial skeleton [interparietal, parietal, and supraoccipital of the skull
bones, bipartite and dumbbelled centrum of the vertebrae, sternum and hyoid] and the partial
ossification of the appendicular skeleton [pubis and ischium] were observed at the highest dose
tested.
In a developmental toxicity study in Hra:(NZW)SPF rabbits, doses of 0, 30, 100, 300,
or 500 mg/kg/day were given by gavage on gestation days 7-19. The NOEL for maternal toxicity
was 100 mg/kg/day. The LOEL for maternal toxicity was 300 mg/kg/day, based on decreased
body-weight gain and food consumption. There were no effects on maternal reproductive
parameters. The NOEL for developmental toxicity was 100 mg/kg/day. The LOEL for
developmental toxicity was 300 mg/kg/day, based on the increase in the percentage of late post-
implantation loss. There was a significant reduction in the number of female pups at the 300 and
500 mg/kg/day dose levels, and there was a significant increase in the mean percentage of skeletal
variations at the highest dose level.
In a two generation reproduction study, Crl:CD BR rats were fed doses of 0, 50, 250, or
2500 ppm bromacil. No effects on reproductive performance were seen. The parental NOEL was
250 ppm (12.5 mg/kg/day). The LOEL was 2500 ppm (125 mg/kg/day), based on significantly
increased incidence of hydronephrosis. The reproductive NOEL was >2500 ppm (125
mg/kg/day).
The developmental data for bromacil indicate developmental effects occurred at doses that
were the same as or higher than doses which cause maternal toxicity. The Agency would
generally be concerned when developmental/reproductive effects are seen at doses lower than
those which cause maternal effects. No effects on reproductive performance were seen in the two
generation rat study. The developmental studies in conjunction with the reproduction study do
not indicate any additional sensitivity of young organisms to bromacil.
25
-------
Uncertainty Factor
Based on reliable data outlined above, the Agency concludes that an additional uncertainty
factor is not warranted for the bromacil chronic risk assessment, nor is the use of an additional
uncertainty factor indicated for estimating risk from acute exposure detailed below.
Aggregate Exposure/Risk
In examining aggregate exposure, FQPA directs EPA to take into account available
information concerning exposures from the pesticide residue in food and all other exposures for
which there is reliable information. These other sources of exposure include drinking water, and
non-occupational exposures, e.g., to pesticides used in and around the home. For estimating acute
and chronic risks the Agency considers aggregate exposures from the diet and from drinking
water. Exposures from uses in and around the home that may be of a short term, intermediate
or other duration may also be aggregated as appropriate for specific chemicals.
Bromacil has no residential or other non-occupational uses that might result in exposure
to adults or children. Therefore, the only considerations for aggregate exposure are those from
food and drinking water.
Acute Risk
The acute toxicity of bromacil by the oral, dermal, and inhalation routes of exposure is
very low. The Agency has identified no acute toxicity endpoints of concern. Acute dietary and
drinking water risk assessments were not conducted for bromacil because acute toxic effects are
not expected at the concentrations of bromacil which are likely to be found in food or drinking
water.
Chronic Risk
Dietary Exposure
A chronic dietary exposure analysis was performed, using tolerance level residues and
assuming that 100 percent of the crops were treated, to estimate the Theoretical Maximum
Residue Contribution (TMRC) for the general population and 22 subgroups.
Existing tolerances result in a TMRC which represents < 1% of the RfD for the U.S.
general population. The highest subgroup, children 1-6 years old occupies 1% of the RfD.
The analysis for bromacil is a worst case estimate of dietary exposure with all residues
assumed to be at tolerance levels and 100 percent of the commodities assumed to have been
treated with bromacil.
26
-------
Tolerances have been established in/on citrus and pineapples at 0.1 ppm. The available
data for bromacil support the established tolerances listed in 40 CFR §180.210. No revocations
or amendments are required at this time. No tolerances exist for residues of bromacil in animal
commodities and no food/feed additive tolerances have been established or need to be established.
Drinking Water Exposure
Extensive data exists as evidence that bromacil leaches to ground water as a result of
normal agricultural use. Data currently available to the EPA indicate that bromacil has been
detected in ground water in 5 states, with concentrations in many Florida wells exceeding 100
ppb.
The data the Agency has on bromacil in South Florida surface water suggests that it is
probably unlikely that the annual average concentrations of bromacil will exceed the lifetime
health advisory or that peak or short term average concentrations will exceed the 1-10 day health
advisory in surface water sources for drinking water in South Florida. The Agency has no other
data on bromacil in surface waters.
Although bromacil residues in water are found above the HAL (90 ppb), the Agency has
determined that an adult drinking 2 liters of water per day over a lifetime containing 100 ppb of
bromacil reaches < 4% of the RfD, and a 10 kg child drinking 1 liter of water containing 100
ppb of bromacil reaches 10% of the RfD. Furthermore, as the infant's/child's body weight
increases with age, the percent of the RfD for consumption of bromacil-contaminated water
decreases.
Non-occupational Exposures
No other sources of chronic exposure to bromacil have been identified.
Conclusion Regarding Chronic Aggregate Exposure to Bromacil
Considering chronic exposures from all sources of bromacil (in this case only food
residues and drinking water residues are relevant), aggregate risks will be < 6% of the RfD for
the general population (< 2% from food and < 4% from water), and < 11% of the RfD for
infants and children (1% from food and 10% from water).
The Agency concludes that aggregate risks to the general U.S. population, and to the
population subgroup of infants and children, resulting from bromacil uses are not of concern.
Cumulative Effects
In assessing the potential risk from cumulative effects of bromacil and other pesticides and
substances with a common mode/mechanism of toxicity, the Agency first considered structural
similarities and common effects that exist between bromacil and other substituted uracil
compounds such as terbacil and lenacil. The Agency then considered other compounds which
27
-------
could potentially result in effects similar to bromacil: induced cystic thyroid follicles; or bromacil-
induced enlargement of centrilobular cells of the liver.
A comparison of the available toxicological database for bromacil and terbacil revealed no
clear commonality of effects. The toxicology database for lenacil was not considered because there
are currently no registered uses and no tolerances for lenacil. Consequently, no dietary or non-
occupational exposure to lenacil is anticipated. A summary of the most prominent clinical signs
from terbacil and bromacil follows.
The following clinical signs were observed in the bromacil toxicology database: decreased
body weight, focal atrophy of seminiferous tubules (testicular abnormalities), hydronephrosis,
suggestive histological evidence for antithyroid activity (cystic follicles in the thyroid and
enlargement of centrilobular cells of the liver) and a positive trend in thyroid tumors for male rats
(basis of C classification for carcinogenicity).
The following clinical signs were observed in the terbacil toxicology database: decrease
in body weight, increase in liver weights, vacuolization and hypertrophy of hepatocytes,
hypertrophy of centrilobular hepatocytes in males, decreased pituitary weights in males and
females, increase in thyroid/body weight ratio, and elevated alkaline phosphatase.
Based on these data, the Agency has determined that there does not appear to be a common
mode/mechanism of toxicity between bromacil and terbacil. With both chemicals, there is
marginal evidence of liver effects (principally enlargement of centrilobular cells). Enlargement
of liver cells is not a specific enough effect to be considered a common mode/mechanism of
toxicity. The thyroid effects observed with bromacil were cystic follicles. Terbacil induced an
increase in relative thyroid weights but no increase in absolute thyroid weights. An increase in
relative weight without a corresponding increase in absolute weight has very little meaning,
especially without any supporting histological or hormonal evidence. This conclusion was based
on the marginal liver effects noted in the databases, and the absence of thyroid effects in the
terbacil database (with the exception of increases in relative thyroid weights).
In evaluating other chemicals with effects similar to bromacil, the Agency determined that
the available data on bromacil are not sufficient to conclude that bromacil induces thyroid tumors
through an antithyroid mode/mechanism of toxicity. Bromacil induces a positive trend in thyroid
follicular cell tumors for male rats with no significant pairwise increases in thyroid tumors at any
dose level. The available studies showed no changes in either T3, T4 or TSH levels, which would
be prime indicators of antithyroid activity. In addition, there were no data available other than
histological indications (cystic thyroid follicles and enlargement of liver cells) to indicate that
bromacil is either affecting the thyroid directly by interfering with iodide uptake or thyroid
hormone production and release or affecting the thyroid indirectly through the liver (increase in
metabolism and excretion of thyroid hormones, thereby inducing the thyroid to grow in order to
produce more hormones). Therefore, available data do not suggest that bromacil has a common
mode/mechanism of toxicity with any other chemical that is known to have antithyroid activity.
28
-------
Therefore, the risk assessment has taken into account only exposures resulting from
bromacil uses.
C. Environmental Assessment
1. Ecological Toxicity Data
Review of the toxicity data found that chronic data were lacking for both aquatic and
terrestrial animals. All of the acute studies fulfill the guideline requirements except the 72-3(b)
acute estuarine and marine toxicity study with mollusk. In summary, the following guideline
requirements are not fulfilled:
Avian Reproduction Quail [71-4 (a)].
Avian Reproduction Duck [71-4 (b)].
Acute Estuarine/Marine Toxicity Mollusk [72-3(b)].
Early Life-Stage Fish [72-4(a)].
Life-Cycle Aquatic Invertebrate [72-4(b)].
Aquatic Plant Growth [122-2].
The following assessment for ecological risk has been conducted for rates up to 32 Ib ai/A,
the maximum label rate allowed for bromacil-containing products prior to this reregistration
review and issuance of the reregistration eligibility decision.
a. Toxicity to Terrestrial Animals
(1) Birds and Reptiles, Acute and Subacute
In order to establish the oral and dietary toxicity of bromacil to birds and reptiles, the
following tests are required using the technical grade material: one avian single-dose oral (LD50)
study on one species (preferably mallard or bobwhite quail) (TABLE 9), and two subacute dietary
studies (LC50) on one species of waterfowl (preferably the mallard duck) and one species of upland
game bird (preferably bobwhite quail) (TABLE 10).

-------
The results summarized in the above two tables indicate that bromacil is practically
nontoxic to avian and reptilian species on an acute oral and subacute dietary basis. The guideline
requirements for the avian acute oral toxicity and avian subacute dietary toxicity studies are
fulfilled. (MRID 40951501 and 00013295)
(2) Birds and Reptiles, Chronic
Avian reproduction studies are required when birds or reptiles may be exposed to bromacil
repeatedly or continuously due to persistence, bioaccumulation, or multiple applications, or if
mammalian reproduction tests indicate reproductive hazard. The field dissipation study shows the
half-life of bromacil in soil is two months, and the labels allow for repeat application. Avian
reproduction studies are not available. These studies are required in order to address the potential
for adverse chronic or reproductive effects to birds and reptiles from bromacil.
(3)
Acute and Chronic Effects to Mammals
Wild mammal testing is required on a case-by-case basis, depending on the results of the
lower tier studies such as acute and subacute testing, intended use pattern, and pertinent
environmental fate characteristics. In most cases, however, the rat acute oral LD50 is used to
determine toxicity to mammals. This LD50 is reported in the table below.

b. Toxicity to Aquatic Animals
(1) Freshwater Fish
Acute Toxicity
In order to establish the toxicity of a pesticide to freshwater fish and amphibians, 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 the rainbow trout), and the
other should use a warmwater species (preferably the bluegill sunfish).

The results of the 96-hour acute toxicity studies (Table 13) indicate that bromacil is slightly
toxic to fish and amphibians. The guideline requirements for freshwater fish acute toxicity are
fulfilled. (MRID 40951503 and 40951502)
Chronic Toxicity
Bromacil labels allow repeat applications and bromacil is persistent in water. Therefore,
it can be expected that bromacil will be in water on a recurrent basis. The EEC in water is
greater than 0.01 of the LC50 for fish. The refined EEC calculations show that the aquatic
concentrations associated with a 4.2 Ibs a.i/A rate of bromacil application are expected to change
very little over a 56 day period (day of application-0.35 ppm, 96 hours-0.349 ppm, 21 days-
0.348 ppm, 56 days-0.347 ppm). Therefore, chronic testing is required.
The fish early life-stage study has not been submitted. These data are needed in order to
determine the chronic risk to freshwater vertebrates.
A fish life-cycle test is required if studies of other organisms indicate the reproductive
physiology of fish and/or amphibians may be affected. The fish life-cycle guideline requirement
is reserved pending the results from the fish early life-stage study.
(2) Freshwater Invertebrates
The minimum testing required to assess the hazard of a pesticide to freshwater
invertebrates is a freshwater aquatic invertebrate toxicity test, preferably using first instar Daphnia
magna or early instar amphipods, stoneflies, mayflies, or midges.

There is sufficient information, as summarized in Table 14, to characterize bromacil as
practically nontoxic to aquatic invertebrates on an acute basis. The guideline requirement for
freshwater invertebrate toxicity is fulfilled. (MRID 40951504)
As described above for fish, relatively high concentrations of bromacil are expected in
water bodies receiving runoff. Therefore, the Daphnia life-cycle test is needed to complete the
ecological effects assessment. This requirement has not been fulfilled.
(3)
Estuarine and Marine Animals
Acute toxicity testing with estuarine and marine organisms is required when an end-use
product is intended for direct application to the marine/estuarine environment, or is expected to
reach this environment in significant concentrations. The terrestrial food and feed uses, terrestrial
nonfood use, and aquatic nonfood uses of bromacil may result in exposure to the estuarine
environment. Therefore, estuarine and marine organism testing is required.
The requirements under this category include a 96-hour LC50 for an estuarine fish, a 96-
hour LC50 for shrimp, and either a 48-hour embryo-larvae study or a 96-hour shell deposition
study with oysters.

There is sufficient information, as summarized in Table 15, to characterize bromacil as

for both the mysid and the sheepshead minnow. (MRID 41588701 and 41588702)
The guideline requirement is not fulfilled for the eastern oyster. The eastern oyster 48
hour embryo-larvae test did not meet the guideline requirements because control organisms in this
study showed over 23% abnormality in shell development, and the laboratory failed to report the
incidence of misshapen or malformed shell development. These abnormal effects may have
masked effects of the herbicide. (MRID 41588703)
Chronic toxicity data are also necessary for completion of the estuarine and marine
ecological effects assessment because relatively high concentrations of bromacil may persist.
32
-------
These data include an estuarine fish early life-stage test and mysid life-cycle test. The data
requirement has not been fulfilled.
c. Toxicity to Plants
(1) Terrestrial
Currently, terrestrial plant testing (seedling emergence and vegetative vigor) is required
for herbicides that have terrestrial nonresidential outdoor use patterns and that have endangered
or threatened plant species associated with the site of application. The above conditions apply for
bromacil and lithium bromacil.
Tier 2 toxicity data on the technical/TEP (95.5% active ingredient) material for the most
sensitive species is given in Table 16 below:

For seedling emergence, rape is the most sensitive dicot and wheat is the most sensitive
monocot. The guideline is fulfilled.
(2) Aquatic
Currently, aquatic plant testing is required for any herbicide that has outdoor non-
residential terrestrial uses that may result in off-site movement by runoff (solubility > 10 ppm
in water), or is applied directly to aquatic use sites (i.e. drainage systems and irrigation ditches,
etc.) as is currently the case for bromacil. The following species should be tested: Selenastrum
capricornutum, Lemna gibba, Skeletonema costatum, Anabaena ttos-aquae, and a freshwater
diatom.
33

Tier 2 toxicity data on the technical material is listed in Table 17 below:

The results summarized in the above table indicate that bromacil is very highly toxic to

costatum, Anabaena flos-aquae, and a freshwater diatom. The value of the studies is considered
to be high because these surrogate species were chosen to represent all aquatic plants. Without
these studies, the susceptibility of potentially more sensitive plants would not be considered. The
guideline requirements are fulfilled for bromacil but not for the lithium salt. (MRID # 42516401).
2.
Environmental Fate
a.
Environmental Fate Assessment
The environmental fate data base for bromacil is largely complete. Bromacil is a persistent
and highly mobile herbicide.
The primary routes of dissipation appear to be photolysis in water under alkaline
conditions and microbial degradation in anaerobic soil. In the laboratory studies, bromacil was
stable to hydrolysis, photodegradation in water at pH's 5 and 7, photodegradation on soil, and
aerobic soil metabolism. However, bromacil in pH 9 buffered solution did photodegrade fairly
rapidly with a half-life of 4-7 days. Under anaerobic conditions, bromacil appeared to degrade
with a half-life of approximately one month, though this study had several major deficiencies that
call into question the validity of this information. Laboratory mobility data, in addition to ground
water monitoring information, have clearly demonstrated that bromacil is highly mobile in soil.
Bromacil's persistence was confirmed with half-lives of 124-155 days in the field dissipation
studies; however its tendency to leach was not apparent from the two studies. The timing and
amount of rainfall/irrigation in these studies is a possible explanation. Bromacil accumulates only
slightly in fish and depurates rapidly. There is evidence that bromacil will contaminate
groundwater, and will move off-site and contaminate surface water.
34
-------
b. Environmental Fate and Transport
(1) Degradation
Hydrolysis. Bromacil is stable to hydrolysis at environmental pHs. Ring-labeled [2-
14C]bromacil at 20 ppm was stable to hydrolysis in sterile aqueous pH 5,7, and 9 buffer solutions
that were incubated in the dark at 25 ± 1°C for 30 days. At 30 days post-treatment, bromacil
comprised 94.4-96.4%, 94.6-99.0%, and 96.5-97.0% of the recovered radioactivity in the pH 5,
7, and 9 solutions, respectively. Unidentified [14C]peaks from TLC analyses of the test solutions
revealed three minor degradates, one of which (Peak II) reached a maximum of 3.9% of the
recovered radioactivity in the pH 7 solution at 30 days. The radioactivity in the trapping solutions
was <0.01% of the applied (MRID 40951505).
Photodegradation in Water. Bromacil is stable to photolysis in water at pH 5 and 7, but
degrades at pH 9 with a half-life of 4-7 days. Apparently, once ionized (pKa 9.1), there is a shift
in the absorption spectrum of bromacil thereby making it susceptible to photolysis. Degradates
in the pH 9 system have not been identified.
In the first photodegradation in water study, ring-labeled [2-14C]bromacil at 20 ppm was
stable in sterile aqueous pH 5 and 7 buffered solutions and degraded rapidly in sterile aqueous pH
9 buffered solutions that were irradiated continuously with a xenon arc lamp at 25 ± 1 °C for 15
days.
Bromacil photodegraded with a calculated half-life of 326 days in the pH 5 test solution.
Bromacil decreased from an average of 97.2-98.0% of the applied radioactivity immediately post-
treatment to 89.0-92.7% of the applied at 17 days post-treatment (15 days of irradiation).
Bromacil photodegraded with a calculated half-life of 102 days in the pH 7 test solution.
Bromacil decreased from an average of 97.1-99.2% of the applied radioactivity immediately post-
treatment to 78.2-80.8% of the applied at 17 days post-treatment (15 days of irradiation). A
maximum of eight unidentified degradates were isolated in the pH 7 solution, each present at
<8.1% of the recovered radioactivity.
Bromacil photodegraded with a calculated half-life of 7 days in the pH 9 test solution.
Bromacil decreased from an average concentration of 96.4-98.0% of the applied radioactivity
immediately posttreatment to 15.8-18.9% of the applied at 7 days, and 3.4-4.4% of the applied
at 17 days post-treatment (15 days of irradiation). The radioactivity in the pH 9 test solution was
not further characterized. In the dark control test solutions, the average concentrations of
bromacil were >96.4% of the applied radioactivity at 17 days post-treatment (15 days of
irradiation). In all test solutions, [14C]volatiles were <0.5% of the applied for the irradiated and
dark solutions during the study. (MRID 40951507)
In a second photodegradation in water study, ring-labeled [2-14C]bromacil at 20 ppm
photodegraded with a half-life of 103.1 hours (4.3 days) in a sterile aqueous pH 9 buffered
35
-------
solution that was irradiated continuously with a xenon arc lamp at 25 ± 1°C for 15 days.
Bromacil was 99.94% of the applied immediately post-treatment, 50.89% at 3 days, 15.86% at
7 days, and 0.81% at 15 days post-treatment. The test solution was not analyzed for degradates
during the study. (MRID 40951508)
Photodegradation on Soil. Bromacil is stable to photolysis on soil. Ring-labeled [2-
14C]bromacil at 0.13 mg/mL (equivalent to 0.12 Ib ai/A), photodegraded with a calculated half-life
of 166 days on silty clay loam soil that was irradiated for 12 hours per day with a xenon arc lamp
for 30 days at 25 ± 1°C.
Based on TLC analysis of the irradiated samples, bromacil decreased from 104.6% of the
applied immediately post-treatment to 90.4% of the applied after 30 days. Two unidentified
degradates (Unknowns I and II) each comprised <2.5% of the applied in the irradiated samples.
At 30 days post-treatment, unextracted [14C]residues totaled 3.6% of the applied; no [
14C]volatiles were detected during the course of the study.
The calculated half-life for the dark controls was 273 days. Based on TLC analysis,
bromacil decreased from 104.6% of the applied immediately post-treatment to 96.7% of the
applied after 30 days; Unknowns I and II were each <2.0% of the applied. At 30 days post-
treatment, unextracted [14C]residues totaled 1.3% of the applied; no [14C]volatiles were detected.

Aerobic Soil Metabolism. Microbial degradation of bromacil in aerobic soil is slow, with
a half-life of 275 days. Ring-labeled [2-14C]bromacil at 9 ppm degraded with a half-life of 275
days in silty clay loam soil that was incubated in the dark at 25 ± 1 °C and 75% of field moisture
capacity for up to 12 months. Bromacil decreased from 98.5% of the applied radioactivity
immediately post-treatment to 53.1% at 184 days, 48.6% at 240 days, and 38.6% at 12 months.
Carbon dioxide was the major degradate, totaling 40.3% of the applied at 12 months post-
treatment. In extracts of sterilized silty clay loam soil, bromacil comprised 87.5% of the applied
at 12 months post-treatment. Metabolites were a maximum of 1.6% of applied radioactivity.
Five nonvolatile degradates were identified:
1) 5-bromo-6-methyluracil (Metabolite G) was a maximum of 3.4% of applied radioactivity
at 304 days post-treatment;
2) 5-bromo-3-(alpha-hydroxymethylpropyl)-6-methyluracil (Metabolite C) was a maximum
of 1.5% of applied radioactivity at 154 and 184 days;
3) 5-bromo-3-sec-butyl-6-hydroxymethyluracil (Metabolite A) was a maximum of 0.6% of
applied radioactivity at 184 days post-treatment;
4) 5-bromo-3-(2-hydroxy-l-methylpropyl)-6-methyluracil (Metabolite D) was a maximum
of 0.8% of applied radioactivity at 304 days; and,

5) 3-sec-butyl-6-methyluracil (Metabolite F) was a maximum of 0.7% of applied
radioactivity at 304 days.

Anaerobic Aquatic Metabolism. This study provides ancillary information and cannot
be upgraded. The study is unsatisfactory because it did not adequately characterize the
degradation of bromacil under anaerobic conditions, which is apparently a major route of
dissipation. The sampling intervals were inadequate to accurately establish the half-life of the test
substance (> 50% degraded between two samplings). Between day 28 and day 93, the percent
applied radioactivity identified as bromacil decreased from 78.1% to 1.3%.
The 39 day half-life calculated by the registrant was based on an assumption that there was
a 28 day lag phase and that the degradation was first-order linear between 28 and 93 days. Only
these two sampling intervals were used to calculate the half-life. The Agency believes the data
are inadequate to accurately define the pattern of decline of bromacil and the patterns of formation
and decline of the metabolites.
The major degradate was 3-sec-butyl-6-methyluracil (Metabolite F) and was a maximum
of 80.7% of the applied at day 304 post-treatment. This product is likely formed through
reductive dehalogenation, a reaction favored under anaerobic conditions.
Since the sampling intervals were inadequate to accurately establish the half-life, the
problems with this study could not be resolved with the submission of additional data. A new
anaerobic aquatic metabolism study using appropriate study intervals is necessary to determine
whether anaerobic aquatic metabolism is a major route of dissipation for bromacil, and to
accurately establish the half-life. (MRID 40951511)
(2) Mobility
Column Leaching. Bromacil is very mobile in sand, sandy loam, clay loam and silt loam
soils. Aged bromacil residues are very mobile in silt loam soils.
Based on column leaching studies, unaged [14C]bromacil was very mobile in columns of
sand, sandy loam, clay loam, and silt loam soils that were treated with ring-labeled [2-
14C]bromacil at 5.49 mg ai/column (approximately equivalent to 27 kg ai/ha) and leached with 20
inches of 0.01 M CaCl2 solution. [14C]Residues in the leachates of all four soils totaled 91.2-
99.6% of the applied; [14C]residues remaining in the soil columns were 2.46-9.37% of the applied
and were distributed throughout the length of the columns. Based on HPLC analyses of the
leachates, bromacil comprised 89.0-94.1% of the applied, and unidentified residues ("other")
totaled < 0.05-6.7% of the applied.
Aged Column Leaching. Based on a column leaching study, aged [14C]bromacil residues
were very mobile in a column of silt loam soil that was treated with ring-labeled [2-14C]bromacil
37
-------
at 63 ppm, incubated for 30 days, and leached with 20 inches of 0.01 M CaCl2 solution.
[14C]Residues in the leachate totaled 87.3% of the applied radioactivity; [14C]residues remaining
in the soil column were 19.5% of the applied and were mostly (11.3% of applied) in the upper
2 inches of the column. Extractable [14C]residues remaining in the soil column were 11.8% of
the applied; of these, bromacil comprised 11.3% of the applied and unidentified residues ("other")
were 0.5% of the applied. Following leaching, bromacil was the only compound identified in the
leachate, comprising 82.8% of the applied radioactivity; unidentified ("other") residues comprised
4.5% of the applied.
The mobility of 3-sec-butyl-6-methyluracil (Metabolite F), the major and persistent
metabolite identified in the Anaerobic Aquatic Metabolism study, was not addressed. However,
this metabolite is not of toxicological concern. Therefore, based on the environmental fate profile
of bromacil, (i.e., its persistence and mobility) and the toxicity information on Metabolite F, no
additional mobility data are needed at this time. (MRID 40951512)
(3) Accumulation
Accumulation in Fish. Bromacil is only slightly accumulated in bluegill sunfish.
Accumulated residues depurate very rapidly.
Bromacil residues accumulated very slightly in bluegill sunfish that were exposed to ring-
labeled [2-14C]bromacil at 1.0 or 10.6 ppm for 28 days under flow-through aquarium conditions.
Total [14C]residues were highest in the viscera tissues of fish exposed to either test concentration,
with bioconcentration factors of 6.8 and 8.3X, respectively.
In fish exposed to 10.6 ppm of ring-labeled [2-14C]bromacil, the maximum
bioconcentration factors were 4.6X for muscle, 6.8X for viscera, 2.IX for carcass, and 2.5X for
whole fish. Maximum mean concentrations of total [14C]residues were 49.2 ppm in muscle (day
21), 72.2 ppm in viscera (day 28), 22.3 ppm in carcass (day 21), and 26.4 ppm in whole fish (day
21). Depuration was rapid, with > 96% of the accumulated [14C]residues eliminated from the fish
tissues by day 3 of the depuration period.
In fish exposed to 1.0 ppm of ring-labeled [2-14C]bromacil, maximum bioconcentration
factors were 4.6X for muscle, 8.3X for viscera, 2.2X for carcass, and 2.8X for whole fish.
Maximum mean concentrations of total [14C]residues were 4.8 ppm in muscle (day 21), 8.6 ppm
in viscera (day 7), 2.3 ppm in carcass (day 14), and 2.9 ppm in whole fish (day 7). Depuration
was rapid, with > 96% of the accumulated [14C]residues eliminated from the fish tissues by day
3 of the depuration period.
During the 28-day exposure period, total [14C]residues, comprised of bromacil exclusively,
ranged from 0.91 to 1.21 ppm for the low dose and 8.8 to 11.4 ppm for the high dose aquaria.
Although identification of accumulated residues is generally required, this information is not
needed in this case due to the very low bioconcentration factors and high depuration rates for
bromacil. (MRID 40951513)

(4) Field Dissipation
In the field, bromacil was persistent, but did not demonstrate the degree of mobility that
was predicted by the laboratory studies and the available ground water monitoring data. In loamy
soils, bromacil was somewhat persistent and demonstrated low to moderate mobility under field
conditions. One possible explanation for the limited mobility at the two sites could be the amount
and timing of rainfall and/or irrigation.
Bromacil (Hyvar X Herbicide, 80% WP), applied in a single ground application at 12 Ib
ai/A, dissipated with half-lives of 155 days from the upper 10 cm of a bare ground plot of silty
clay loam soil located in Delaware, and 124 days from the upper 10 cm of a bare ground plot of
loam soil located in California. Bromacil was detected in the upper 10 cm of the Delaware and
California plots through 538 and 415 days posttreatment, respectively. In general, bromacil was
not detected below the 40 cm soil depth at both test sites.
1) Newark, Delaware. Average concentrations of bromacil in the 0- to 10-cm depth were
9.71 ppm immediately post-treatment, 4.69 ppm at 30 days, 3.59-4.17 ppm at 90-181
days, 1.97 ppm at 359 days, and 0.41 ppm at 538 days post-treatment. In the 10- to 20-
cm depth, average concentrations of bromacil varied with no discernible pattern, and were
a maximum of 0.36 ppm at 243 days post-treatment. In the 20- to 40-cm depth, bromacil
was an average of 0.17 ppm immediately post-treatment, 0.05 ppm at 14 days, and was
generally <0.03 ppm from 30-538 days post-treatment. In general, bromacil was not
detected below the 40-cm soil depth.
2) Madera, California. Average concentrations of bromacil in the 0- to 10-cm depth were
8.28 ppm immediately post-treatment, 4.65 ppm at 29 days and 4.07 ppm at 59 days,
2.85-3.31 ppm at 89-179 days, and 0.48 ppm at 415 days post-treatment. In the 10- to 20-
cm depth, average concentrations of bromacil were 0.31 ppm immediately post-treatment,
then < 0.01-0.30 ppm with no discernible pattern through 415 days post-treatment. In the
20- to 40-cm depth, bromacil was an average of 0.09 ppm immediately post-treatment and
generally was not detected by 15 days post-treatment, although it was 0.02-0.04 ppm in
isolated samples taken at 179-415 days post-treatment. In general, bromacil was not
detected below the 40-cm soil depth. (MRID 41677101)
c. Water Resources
(1) Ground Water
Extensive data exists as evidence that bromacil leaches to ground water as a result of
normal agricultural use. Less data is available to determine the impact of bromacil applications
from use on rights-of-way. Data currently available to the EPA indicate that bromacil has been
detected in ground water in 5 states, with concentrations in many Florida wells exceeding 100
ppb. Because of this, bromacil exceeds the following levels of concern:
39
-------
1) Human Health. Bromacil has been detected in ground water at concentrations that exceed
the lifetime health advisory level (HAL) of 90 ppb, and has maintained concentrations
above that level in many wells. Wells in Sebring, Florida have shown levels of bromacil
near the HAL 30 months after detections were originally found above 90 ppb.
2) Ground Water Quality. Bromacil has been shown conclusively from groundwater
monitoring data to leach to ground water, diminishing the quality of the resource. In areas
of the Central Ridge of Florida, such as DeSoto City, ground water contaminated with
bromacil has remained contaminated for several years. In addition, concentrations of
bromacil in these Florida wells do not consistently decrease with time, even with
reductions in the application rate of the chemical.
3) Non-target Plants. Bromacil is highly toxic to aquatic plants, with an EC50 for
Selenastrum capricornatum of 6.8 ppb. This is of particular concern in Florida, where
because of high water tables, ground water discharges into drainage canals, which
ultimately drain into surface water bodies. In addition, bromacil has been found in ground
water at concentrations that exceed levels-of-concern for non-target terrestrial plants, as
determined by seedling-emergence studies. This could be a concern in areas where
contaminated ground water is used for irrigation.
Small-Scale Retrospective Ground Water Monitoring Studies. DuPont conducted retrospective
ground water monitoring studies in three citrus-growing regions (Central Ridge, Flatwoods and
Coastal) of Florida between 1987 and 1990. Bromacil was detected in ground water at all three
study sites, as described below.
1) Central Ridge. Bromacil was detected in all 10 wells at this site, with well depths
ranging from 14 to 54 feet. Five of these wells had at least one detection above the 90 ppb
Health Advisory Level (HAL), with a maximum concentration of 156 ppb.
Concentrations of bromacil at this site did not decrease with time in these monitoring
wells, although the application rate of bromacil was decreased throughout the study.
2) Flatwoods. Bromacil was detected in all three of the monitoring wells installed at this
site, with a maximum detection of 21.8 ppb.
3) Coastal. Bromacil was detected in three of the four monitoring wells at this site, with a
maximum concentration of 147 ppb. The three wells with detections were screened from
5 to 10 feet. The well without detections was screened from 50 to 60 feet.
40
-------
State Ground Water Monitoring Studies.
1) Florida. Although bromacil is used in many states, the greatest use has been on citrus
crops in Florida. In addition, the most extensive ground water monitoring for bromacil
has been in Florida. As a result of this monitoring, it has become clear that contamination
of ground water with bromacil has occurred to varying degrees throughout the citrus-
growing regions of the state.
The region with the greatest concern is the Central Ridge of Florida. In response
to a large number of bromacil detections in drinking water wells at levels above the HAL
(90 ppb), the State of Florida has suspended use of bromacil in this region, pending
evaluation of mitigation measures proposed by DuPont. DuPont is conducting a
prospective field-scale ground water monitoring study to determine if additional reduction
of the application rate will prevent bromacil from contaminating ground water at levels
greater than the HAL in this area.
Bromacil has been one of the pesticides tracked in Florida's Pesticide
Contamination Monitoring System. This system keeps a running total of ground water
samples analyzed for bromacil, and the number of samples with concentrations above and
below the 90 ppb health advisory level. As of May 1995, 2837 wells were sampled for
bromacil; 899 had detections below the HAL, and 57 had detections above the HAL. Of
this number, 679 of the wells with detections below the HAL, and 55 with detections
above the HAL were from Highlands County, in the Central Ridge. Polk County recorded
121 wells with detections below the HAL, and 1 above the HAL. Lake County followed
with 70 wells with detections below the HAL, then Hardee County with 16 wells with
detections below and one with detections above the HAL.
A separate study performed in Collier County, in the Flatwoods region of southern
Florida, had detections well above the HAL in shallow ground water. In a report on this
study l, detections of bromacil in ground water are listed at concentrations as high as 1422
ppb. These samples were collected at the very top of the water table, from wells with one-
foot screens. The State of Florida does not consider bromacil to be a ground water concern
in the Flatwoods region, as there is generally a low-permeability spodic layer near the
surface, perching this uppermost saturated zone. However, as a result, the contaminated
shallow ground water is available for transport into surface water through drainage
ditches.
2) Texas. While bromacil use is greatest in Florida, significant amounts are also applied in
California and Texas for both citrus and right-of-way uses. Contacts at the Texas
Department of Agriculture and Texas Natural Resource Conservation Commission
1 Dwinell, S., 1990. "Movement of Bromacil in a Collier County Citrus Grove: Evaluation of the GLEAMS
Model". Florida Dept. of Envir. Regulation.
41
-------
reported that the State of Texas does not have records of bromacil analysis of ground
water samples more recent than 1988. The Agency's "Pesticides in Ground Water Data
base" reports that bromacil was detected in 6 of 230 wells sampled in Texas between 1983
and 1989.
3) California. In 1994, the Department of Pesticide Regulation of the California
Environmental Protection Agency (CalEPA) reported that bromacil was one of 5 pesticides
for which detections were "verified" in California groundwater as a result of non-point
agricultural use within the past year. CalEPA defines a detection as "verified" when (a)
the pesticide (or breakdown product) is detected in two discrete samples taken from a
single well during a 30-day period AND (b) the second sample is analyzed either by the
same laboratory using different analytical methods or by two laboratories using the same
method (analytical methods must have been approved by the department of pesticide
regulators. Bromacil was detected in two other wells but these detections could not be
verified because bromacil was not detected in the second discrete samples from these
wells. Bromacil detection was verified in 4 wells in 2 counties in 1994 where it had not
been previously detected, and found but not verified in two new wells in two other
counties.
In California, the quality of groundwater is managed by the use of Pesticide
Management Zones (PMZs). A PMZ is an approximately square-mile area designated as
sensitive to ground water contamination. PMZs are created based on verified detections
in groundwater of a particular pesticide residue. PMZs are chemical specific; there are
bromacil PMZs, simazine PMZs, diuron PMZs, etc.
California has designated bromacil a "restricted material" for crop uses. Use of
bromacil on crops in bromacil PMZs requires a permit. Noncrop use of bromacil is not
allowed under any conditions in bromacil PMZs.
CalEPA monitors compliance within PMZs to ensure pesticides are not reapplied
in these areas, and to determine if previously detected residues are still present in the soil.
About 10% of existing PMZs are retested each year. In 1994, soils were sampled in non-
crop and row areas and analyzed for bromacil. Residues of bromacil were reported in
three of five PMZs at levels ranging from 50 to 240 ppb. These residues were considered
to have resulted from normal agricultural use before the PMZ was established.
In addition to the Update Report2, CalEPA provided a copy of a data base of
bromacil analyses in ground water, which consisted of over 6800 entries. Among these
are 282 positive detections in 12 counties. The highest concentration recorded in the data
base was 20 ppb from a well in Tulare County.

-------
(2) Surface Water
Substantial amounts of bromacil could be available for runoff to surface waters for several
months post-application (aerobic soil metabolism half-life of 275 days, terrestrial field dissipation
half-lives of 124 to 155 days). The low soil/water partitioning of bromacil (SCS/ARS data base
Koc of 32) indicates that most bromacil runoff will be via dissolution in runoff water as opposed
to adsorption to eroding soil.
Bromacil is susceptible to direct aqueous photolysis at pH 9 where a substantial portion
of it is anionic (pKa = 9.1). However, it is not susceptible to direct aqueous photolysis at pH 5
or 7, to abiotic hydrolysis or to volatilization from water (Henry's Law Constant = 1.1 X 10 9
atm*m3/mol). The stability of bromacil to abiotic processes (except at highly alkaline pHs)
coupled with only a moderate susceptibility to microbiological degradation under aerobic
conditions indicates that bromacil will be persistent in the water column of non-alkaline surface
waters with long hydrological residence times. Bromacil appears to be more susceptible to
degradation by microbes under anaerobic conditions which suggests that bromacil will be less
persistent in typically anaerobic sediments than in typically aerobic water columns. However, the
low soil/water partitioning of bromacil indicates that most of the bromacil in surface water will
be dissolved in the water column as opposed to adsorbed to suspended and bottom sediment.
Reported BCF values for bromacil in the bluegill sunfish were low and depuration rates were
high. Therefore, the bioaccumulation potential of bromacil appears to be low.
Although several degradates of bromacil have been identified in laboratory studies under
aerobic conditions, none are classified as major since none represent >10% of applied
radioactivity at any time during the studies. However, under anaerobic conditions, 3-sec-butyl-6-
methyluracil was identified as a major degradate. The available data are not sufficient to assess
its persistence and mobility.
The South Florida Water Management District (Miles and Pfeuffer 1994) summarized
bromacil detections in samples collected every two to three months from 27 surface water sites
within the SFWMD from November 1988 through November 1993. Approximately 810 samples
(30 sampling intervals X 27 sites sampled/interval) were collected from the 27 sites from
November 1988 through November 1993. Bromacil was detected (above detection limits
generally ranging from 0.002 to 0.25 ppb) in 56 samples. Of the 56 detects, two were greater
than 10 ppb (14 and 11.1 ppb), nine were between 2 and 10 ppb, twelve were between 1 and 2
ppb, and the remaining 33 detects were below 1 ppb.
The Louisiana Department of Agriculture and Forestry reported 3 detections (detection
limit not specified) of bromacil ranging from 0.4 to 1.73 ppb in 84 samples collected in 1992 from
6 Louisiana water districts. The Louisiana Department of Agriculture and Forestry reported 12
detections (detection limit not specified) of bromacil ranging from 0.13 to 2.63 ppb in 48 samples
collected monthly May-October 1993 from 8 locations in 5 Louisiana water districts. Three of the
12 detections were greater than 1 ppb.
43
-------
Bromacil is not currently regulated under the Safe Drinking Water Act (SDWA). Therefore
no MCL has been established for it and water supply systems are not required to sample and
analyze for it. It has lifetime and 1 and 10 day drinking water health advisories of 90 |ig/L and
5000 ppb, respectively. The data the Agency has on bromacil in South Florida surface water
suggest that it is probably unlikely that the annual average concentrations of bromacil will exceed
the lifetime health advisory or that peak or short term average concentrations will exceed the 1-10
day health advisory in surface water sources for drinking water in South Florida. The Agency
does not have any other data on bromacil in surface waters. The Agency believes bromacil is
unlikely to pose any substantial risks to surface source drinking water anywhere.
In summary, bromacil is mobile in soil, persistent in both soil and water and degrades
more rapidly under anaerobic conditions than under other conditions.
3. Exposure and Risk Characterization
a. Ecological Exposure and Risk Characterization
Explanation of the Risk Quotient (RQ) and the Level of Concern (LOG):
The Levels of Concern (LOG) are criteria used to indicate potential risk to nontarget
organisms. The criteria indicate that a chemical, when used as directed, has the potential to cause
undesirable effects on nontarget organisms. There are two general categories of LOG (acute and
chronic) for each of the four nontarget faunal groups and one category (acute) for each of two
nontarget floral groups. In order to determine if an LOG has been exceeded, a RQ must be
derived and compared to the LOC's. A RQ is calculated by dividing an appropriate exposure
estimate (e.g. the estimated environmental concentration [EEC]) by an appropriate toxicity test
effect level (e.g. the LC50). The acute effect levels typically are:
-EC25 (terrestrial plants),
-EC50 (aquatic plants and invertebrates),
-LC50 (fish and birds), and
-LD50 (birds and mammals)
The chronic test results are the NOEC for avian and mammal reproduction studies, and
either the NOEC for chronic aquatic studies, or the Maximum Allowable Toxicant Concentration
(MATC), which is the geometric mean of the NOEC and the LOEC for chronic aquatic studies.
When the RQ exceeds the LOG for a particular category, risk to that particular category
is presumed to exist. Risk presumptions are presented in Table 18 along with the corresponding
LOCs.

(1) Exposure and Risk to Nontarget Terrestrial Animals
(a) Birds and Reptiles
The risk quotient (RQ) used to determine if the level of concern has been exceeded is the
EEC divided by the LC50. However, the available studies did not determine an LQ, value.
Since the mallard study shows no toxic effects for mallard ducks at the highest level tested (10,000
ppm) and in the quail study the quail appear to be near their effect threshold, a conservative LC50
was derived based on two assumptions: 1) that the slope was 5.78 (this was the average from Hill
et al. 1975), and 2) that the LC10 was 10,000 ppm. Table 20 shows RQs calculated from an
estimated LC50 of 16,662 ppm. This estimate was derived using the following formula from Hill
(etal. 1975):
Log LC50 = (5 - probit/slope)+logLC10

Restricted use RQs are exceeded at the 24 and 32 Ib. a.i./A rates, and the endangered
species RQs are exceeded at the 8.7, 24, and 32 Ib. a.i./A rates.
Chronic RQs could not be determined because chronic/reproductive studies were not
available. Bromacil is expected to persist (field dissipation study shows bromacil half-life of 2
months), and multiple applications are expected. Also, mammalian chronic studies show effects
at concentrations expected in the environment. Based on this, an avian reproduction study is
required to complete the ecological effect assessment.

The following equation was used to determine the RQ's:

Summary of Mammalian Acute Effects.
For the liquid formulations, the acute mammalian RQs exceeded the nonendangered
species LOCs at 16 Ib. a.i./A rate and above, and the endangered species LOCs at all rates. RQs
exceeded the restricted use LOCs at the 4.24 and 6 Ib. a.i./A use rates.
Mammalian acute LOCs were exceeded for all application rates for the granular
formulations except at the 8.7 Ib ai/A application rate. That rate exceeded the endangered species
and restricted use LOCs.
Summary of Mammaliam Chronic Effects.
Chronic effects were observed in a 2 year rat reproduction study at concentrations above
250 ppm (NOEL). The following effects were seen at the 2,500 ppm (LOEC) level: body weight
reductions in both sexes of both generations (parental (P) and offspring (Fl)), food consumption
in male offspring (Fl), and body weight reduction in the offspring of the offspring (F2).
51
-------
Although, all uses exceeded the mammalian chronic LOCs the significance of the exceedances is
uncertain due to the nature of the parameters affected.
(a) Insects
The results of the honey bee acute toxicity study show that honey bees are relatively
insensitive to bromacil (LD50 193.3 jig a.i./bee). Based on this low risk, no label warnings are
required.
(1) Exposure and Risk to Nontarget Aquatic Animals
Expected Aquatic Concentrations: Two different EECs were calculated: the GENEEC
derived EEC, and the direct application EEC. The direct application scenario may be appropriate
for several of the use patterns. For example, drainage systems, rights-of-way, recreation areas,
and citrus often are in very close association with drainage systems, irrigation ditches and
wetlands. The GENeric Expected Environmental Concentration (GENEEC) program is a simple
model that uses a chemical's soil/water partition coefficient and degradation half-life values to
estimate runoff from a ten hectare field into a one hectare by two meter deep pond. This program
calculates both acute and chronic generic expected environmental concentration (EEC) values.
It considers reduction in dissolved pesticide concentrations due to adsorption of pesticide to soil
or sediment, incorporation, and degradation in soil before washoff to a water body. It also
includes direct deposition of spray drift into the water body, and degradation of the pesticide
within the water body.
EEC values from GEENEC (TABLE 25) range from 0.264 to 2.63 ppm. EEC values
calculated using the direct application scenario (applying the pesticide to the surface of the water
at normal application rates) ranged from 2.35 to 23.49 ppm. The direct application scenario may
be appropriate for several use patterns, including, drainage systems, rights-of-way, recreation
areas, and citrus which are often in very close association with drainage ditches, irrigation ditches
and wetlands.

2Direct application to water is possible (i.e., drainage systems, irrigation ditches etc.). Therefore, an EEC was provided for direct application to
a 6" deep pond.
Based on the RQs calculated using the GENEEC model, use patterns with an application
rate of 32 Ibs a.i./A for the granular formulation (rights-of-way, non-agricultural uncultivated,
and industrial outdoors), and an application rate of 24 Ibs a.i./A for both liquid and granular
formulations, exceed the acute endangered species LOG for freshwater fish and amphibians.
Application rates that were equal to or less than 16 Ibs a.i./A, granular or liquid formulations, did
not exceed any LOG. The restricted use and the acute nonendangered species LOCs are not
exceeded.
Direct application EECs were also used to calculate RQs for citrus, drainage systems, and
rights-of-way use patterns. Typical use of bromacil is expected to result in the direct application
of the chemical to the surface of water found in irrigation ditches in citrus groves, ditches along
right-of-ways, and drainage ditch systems. Both fish and/or amphibians may use these ditches and
drainage ways.
Only the granular formulation used at 32 Ibs a.i./A exceeded the nonendangered freshwater
fish acute LOG. The restricted use freshwater fish acute LOG is exceeded for the 16, 24, and 32
Ibs a.i./A rates for both granular and liquid formulations. The endangered freshwater fish acute
LOG was exceeded for all use patterns for both liquid and granular formulations.

"Semi-aquatic" plants are plants that usually inhabit low-lying wet areas that may or may
not be dry certain times of the year. These plants are not obligatory aquatic plants in that they
do not live in a continuously aquatic environment. The terrestrial and "semi-aquatic" plants are
exposed to pesticides from runoff, drift, or volatilization.
Runoff exposure is determined from two simple formulas. Runoff to an adjacent area
receiving sheet runoff from one treated acre, or a channelized runoff from 10 treatment acres to
a low lying area some distance away that may expose semi-aquatic and terrestrial plants.
EECs and RQs have been determined for nontarget terrestrial and semi-aquatic plants that
may be exposed from the application of bromacil (TABLE 32). The EC25 value of the most
sensitive species in the seedling emergence study was used with runoff exposure to determine the
RQ.
All RQs exceeded the LOG for both endangered and nonendangered species. The RQ
range for the channel runoff scenario was 151 to 1132 for liquid formulations. The RQ range for
sheet runoff was 411 to 1368 for granular formulations.

(b) Aquatic
Exposure to nontarget aquatic plants may occur through runoff from terrestrial sites. Of
course, aquatic plants are directly exposed from aquatic weed control use. However, because they
are the "target area" for that use, risk from such exposure is not estimated.
The surrogate duckweed, Lemna gibba, is usually used in developing the risk assessment
for aquatic vascular plants. Algae and diatom risk assessments are useful surrogates to
determining the impact to food sources of aquatic organisms.
As shown in TABLE 33 all of the application rates are expected to produce EECs above
the EC50. The RQ will be greater than one, thereby exceeding the endangered and nonendangered
LOG.

(3) Endangered Species
Endangered species acute LOCs have been exceeded for birds, mammals, aquatic
organisms, and plants. Once the Agency's Endangered Species Protection Program is developed
limitations in the use of bromacil and lithium salt of bromacil will be required to protect
endangered and threatened species, but these limitations have not been defined and may be
formulation specific. EPA anticipates that a consultation with the Fish and Wildlife Service will
59
-------
be conducted in accordance with the species-based priority approach described in the Program.
After completion of consultation, registrants will be informed if any required label modifications
are necessary. Such modifications would most likely consist of the generic label statement
referring pesticide users to use limitations contained in county Bulletins.
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 bromacil active ingredients. The Agency has completed its review of these generic
data, and has determined that the data are sufficient with certain limitations to support
reregistration of all products containing bromacil. Appendix B identifies the generic data
requirements that the Agency reviewed as part of its determination of reregistration eligibility of
bromacil, and lists the submitted studies that the Agency found acceptable.
Except for limitations discussed later, the data identified in Appendix B were sufficient to
allow the Agency to assess the registered uses of bromacil and to determine that bromacil can be
used without resulting in unreasonable adverse effects to humans and the environment when used
with the risk mitigation measures required in this decision document. The Agency therefore finds
that all products containing bromacil 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, published scientific literature, etc. and the data identified in Appendix B.
Although the Agency has found that all uses of bromacil 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 bromacil, if new
information comes to the Agency's attention or if the data requirements for registration (or the
guidelines for generating such data) change.
B. Determination of Eligibility
1. Eligibility Decision
Based on the reviews of the generic data for the active ingredients in this case, the Agency
has sufficient information on the health effects of bromacil and its lithium salt, but has certain
limitations on their potential for causing adverse effects in fish and wildlife and the environment
(see section IVC5 below). The Agency has determined that bromacil products, if labeled and used
as specified in this Reregistration Eligibility Decision, will not pose unreasonable risks of adverse
60
-------
effects to humans or the environment. Under the Food Quality Protection Act of 1996, the
Agency has determined that there is a reasonable certainty that no harm will result to infants and
children or to the general population from aggregate exposure to bromacil. Therefore, the
Agency concludes that products containing bromacil for all uses are eligible for reregistration.
2. Eligible and Ineligible Uses
The Agency has determined that all uses of bromacil are eligible for reregistration subject
to conditions imposed in this RED.
C. Regulatory Position
The following is a summary of the regulatory positions and rationales for bromacil issues.
Where labeling revisions are imposed, specific language is set forth in Section V of this document.
To lessen worker risk, and ecological and water quality risks posed by bromacil, EPA is
requiring the following mitigation measures from registrants of bromacil-containing products.
o For all risk concerns:
-Reduce the maximum rate of application from 32 Ibs ai/A to 12 Ibs ai/A (except for
undersurface treatment of toxic-waste holding ponds at 25 Ibs ai/A).
o To protect workers:
-Additional PPE are being required for workers mixing, loading, and applying bromacil.
Chemical resistant gloves are required for most of the formulations during mixing and
loading. A dust mask is required for the wettable powder formulation.
-The total number of acres that may be treated in one day by a worker is being restricted
to five for the toxic-waste holding pond liner treatment.
o To protect non-target organisms:
-Continue existing label warnings addressing the potential exposure of very sensitive areas,
such as wetlands, to bromacil. Remove label instructions that allow direct application to
water (e.g. treating ditchbanks).
o To protect water resources, the Agency is requiring that registrants:
-Develop training materials to explain management practices that can reduce potential for
contamination of water resources and exposure to non-target organisms.
-Standardize use rates for certain weed control situations (i.e. for use in citrus orchards
or to control specific problem weeds).
-Change labels to specify the time of application.
In addition, the Agency supports risk mitigation measures taken by the states of California
and Florida to protect their groundwater resources. These include the ban on use of bromacil on
the Central Ridge of Florida and the creation of Pesticide Management Zones for bromacil in
California.
61
-------
The Agency's concerns and risk mitigation measures are discussed in more detail below.
1. Food Quality Protection Act Findings
a. Determination of Safety for US Population
EPA has determined that the established tolerances for bromacil meet the safety standards
under the FQPA amendments to section 408(b) (2) (D) for the general population. In reaching this
determination, EPA has considered available information on the aggregate exposures (both acute
and chronic) from non-occupational sources, food and drinking water, as well as the possibility
of cumulative effects from bromacil and other chemicals with a similar mechanism of toxicity.
Since there are no residential or lawn uses of bromacil, no dermal or inhalation exposure
is expected in and around the home. No acute toxicity endpoints of concern have been identified
for bromacil.
In assessing chronic dietary risk, EPA estimates that bromacil residues in food account for
< 2% of the RfD and residues in drinking water account for < 4% of the RfD. Thus the
aggregate exposures from all sources of bromacil (in this case, only dietary and drinking water
exposures are relevant) account for < 6% of the RfD for the general population. Therefore, the
Agency concludes that aggregate risks for the general population resulting from bromacil uses are
not of concern.
In evaluating the potential for cumulative effects, EPA compared bromacil with other
structurally similar substituted uracil compounds, and then with other compounds producing
similar effects. Based on available data, EPA concludes that there is currently no reliable
information available to indicate that the toxic effects produced by bromacil would be cumulative
with those of any other chemical compounds.
b. Determination of Safety for Infants and Children
EPA has determined that the established tolerances for bromacil meet the safety standard
under the FQPA amendment to section 408(b)(2)(C) for infants and children. The safety
determination for infants and children considers the factors noted above for the general
population, but also takes into account the possibility of increased dietary exposure due to the
specific consumption patterns of infants and children, as well as the possibility of increased
susceptibility to the toxic effects of bromacil residues in this population subgroup.
In determining whether or not infants and children are particularly susceptible to toxic
effects from bromacil residues, EPA considered the completeness of the data base for
developmental and reproductive effects, the nature of the effects observed, and other information.
Based on the current data requirements, bromacil has a complete data base for
developmental and reproductive toxicity. In the developmental studies effects were seen in the
62
-------
fetuses only at the same or higher dose levels than effects on the mothers. In the reproduction
study, no effects on reproductive performance were seen. EPA concludes that it is unlikely that
there is additional risk concern for immature or developing organisms. Finally, that Agency has
no epidemiological information suggesting special sensitivity of infants and children to bromacil.
Therefore, EPA finds that an additional uncertainty factor is not warranted for assessing the risks
of bromacil.
EPA estimates that bromacil residues in the diet of infants and children account for 1%
of the RfD and residues in drinking water account for 10% of the RfD. Thus the aggregate
exposure from all sources of bromacil account for only 11% of the RfD for infants and children.
Therefore, the Agency concludes that aggregate risks for infants and children resulting from
bromacil uses are not of concern.
In deciding to continue to make reregistration determinations during the early stages of
FQPA implementation, EPA recognizes that it will be necessary to make decisions relating to
FQPA before the implementation process is complete. In making these early, case-by-case
decisions, EPA does not intend to set broad precedents for the application of FQPA to its
regulatory determinations. Rather, these early decisions will be made on a case-by-case basis and
will not bind EPA as it proceeds with further policy development and any rulemaking that may
be required.
If EPA determines, as a result of this later implementation process, that any of the
determinations described in this RED are no longer appropriate, the Agency will consider itself
free to pursue whatever action may be appropriate, including but not limited to reconsideration
of any portion of this RED.
2. Tolerance Reassessment
The available data support the current tolerances for bromacil per se at 0.1 ppm in/on
citrus and pineapples (40 CFR §180.210). The available data support these tolerances. No
tolerances in animal commodities (milk, eggs, animal fat, meat, and meat byproducts) or
tolerances for food/feed additives have been established, nor do they need to be based on the
reviewed data base. However, the commodity definitions for citrus and pineapple need to be
changed to agree with current definitions.
63
-------
A summary of the bromacil tolerance reassessment and modifications in commodity
definitions is presented in Table 34.

CODEX HARMONIZATION
No maximum residue limits (MRLs) for bromacil have been established by Codex for any
agricultural commodity. Therefore, no compatibility questions exist with respect to U.S.
tolerances.
3.
Cancer Risk Assessment
The Office of Pesticide Programs has classified bromacil as a Group C (possible human)
carcinogen and believes that the RfD approach should be used for quantification of human dietary
risk of cancer. This decision was based on the increased incidence of liver tumors in male mice,
and positive trends in thyroid tumors in male rats, and on limited support from SAR compounds.
In the dietary risk assessment above, the Agency concluded the potential chronic risk from
dietary exposure is not of toxicological concern. Even with very conservative assumptions (e.g.
dietary residues at tolerance levels and 100% of citrus and pineapple treated), chronic dietary
exposures occupy no more than 1% of the RfD for the general population or any subgroup.
Since the Agency does not expect workers to be exposed to bromacil for a substantial
portion of their lives and since there are no residential uses of bromacil, the Agency is not
estimating the risk of cancer from this type of exposure. Therefore chronic occupational and
residential exposure and risk estimates were not calculated for bromacil.
4.
Benefits from Use of Bromacil
Bromacil has benefits in vegetation management on agricultural and industrial sites.
Industrial benefits include reduced cost of road and railway repair and reconstruction. Use of
bromacil also enhances visibility on these sites. In addition, its use should also reduce the hazard
from fire or electric shock in oil wells, refineries, electric substations, as well as roads and tracks.
64
-------
5. Ecological Effects Risk Mitigation
The risk assessment shows that various levels of concern (LOCs) have been exceeded for
acute toxicity to both plants and animals. For plants, LOCs are exceeded by very large margins
in virtually all use situations. Mitigation measures, including reduction in rates and requirements
to reduce spray drift reduce the risk.
For animals, LOCs based on conservative screening models, have been exceeded for acute
toxicity to birds, reptiles, and mammals at the higher rates (e.g. in table 37 the risk quotient is
1.37 for herbivores exposed to foodstuffs treated with 24 Ib a.i./A of the liquid formulation). In
addition, the concentration of bromacil that is expected in puddles or shallow irrigation ditches
due to direct application exceeds the fish and amphibian LOCs at almost all application rates (e.g
in table 39 the risk quotients range from 0.07 to 0.48 for 3.2 and 24 Ib ai/acre).
Several factors reduce the Agency's concern regarding these LOG exceedances. The
very highest rates (e.g. 24 and 32 Ib ai/A) where the greatest exceedance occurs are no longer
allowed for all but one very limited use (up to 25 Ib ai/A is allowed for undersurface treatment
for toxic waste holding ponds). Risk quotients at the typically applied rates (around 4 Ibs a.i./A)
are not as high (in table 39 at 4.24 Ib ai/A the RQ is 0.09, exceeding the acute level of concern
for endangered species). Secondly, the screening model is weighted in uncertainty towards
conservatism. And finally, the hazard studies show that bromacil is practically nontoxic to these
animals and, for birds and reptiles, the LOG exceedance is likely an artifact of the extrapolations
more than an indication of actual risk.
Potential chronic risks are considered very relevant in predicting ecological risk from
bromacil, more so than acute risk. Potential for chronic exposure to bromacil for non-target
terrestrial and aquatic animals is considered to be high as a result of bromacil's persistent nature
in soil and water, and the label's allowance of repeat applications.
The Agency was unable to complete its assessment of the chronic and reproductive effects
from exposure to bromacil since it lacked the necessary studies to assess risk. These data are
needed because bromacil's use and chemical characteristics meet the Agency's criteria for
requiring chronic and reproductive testing for birds, freshwater and estuarine and marine fish
and invertebrates. In addition, other ecological fate and effects data are required to complete the
generic data requirements. The studies necessary for this assessment are being called in through
a Data Call-in Notice and are due in 1998.
Although the ecological effects risk assessment cannot be completed until chronic data are
submitted and reviewed, the Agency is taking certain measures to mitigate potential ecological
risks from bromacil, such as the reduction of maximum application rates of 32 to 12 Ibs ai/A and
the elimination of the use on ditch banks. Label warnings address the potential exposure of very
sensitive areas, such as wetlands, to bromacil. The registrant has proposed to remove direct
application to aquatic sites from labels.
65
-------
In making a reregistration decision the Agency weighs the risk against the benefits from
using a chemical. The risk reduction measures required in this RED, namely reduction in
application rates and restrictions on aquatic use, are consistent with those imposed for other
chemicals for which acute, chronic or reproductive risk to nontarget species in the environment
have been proven. Because of this reduction in risk, coupled with the benefits of vegetation
management from using bromacil, the Agency does not believe the remaining risk of chronic and
reproductive effects to non-target species to be unreasonable during the interim period until data
on the chronic effects of bromacil are submitted and evaluated.
6. Spray Drift
The Agency has been working with the Spray Drift Task Force, EPA Regional Offices and
State Lead Agencies for pesticide regulation to develop the spray drift best management practices.
The Spray Drift Task Force has completed their studies, and have submitted their data, and now
the Agency is evaluating it, to determine whether further refinements in spray drift management
practices are needed. The Agency has put in place interim measures to reduce spray drift while
waiting for the data to be reviewed. Products which can be aerially applied will have new
requirements and advisories directed at the applicator to reduce off-target spray-drift.
7. Endangered Species Program
Currently, the Agency is developing a program ("The Endangered Species Protection
Program") to identify all pesticides whose use may cause adverse impacts on endangered and
threatened species and to implement mitigation measures that may eliminate the adverse impacts.
The program would require use restrictions to protect endangered and threatened species at the
county level. Consultations with the Fish and Wildlife Service may be necessary to assess risks
to newly listed species or from proposed new uses. In the future, the Agency plans to publish a
description of the Endangered Species Program in the Federal Register and have available
voluntary county-specific bulletins. Because the Agency is taking this approach for protecting
endangered and threatened species, it is not imposing label modifications at this time through the
RED. Rather, any requirements for product use modifications may occur in the future under the
Endangered Species Protection Program.
8. Groundwater Protection Requirements
Overall
The Agency's strategy for reducing risk to groundwater from bromacil use is two-pronged
and based on its pattern of use. For all use patterns the Agency is pursuing risk reduction through
education of applicators about practices that can reduce potential for groundwater contamination.
In citrus, the Agency has focused risk reduction measures on increasing the monitoring of levels
of bromacil in groundwater. In non-crop areas, the majority of risk reduction is achieved by
reduction of maximum rates by more than half (from 32 Ib ai/A to 12 Ib ai/A) for all but the
undersurface treatment for toxic waste pond liners (25 Ib ai/acre).
66
-------
In addition, the Agency supports risk mitigation measures taken by the State governments
of California and Florida, namely a ban on the use of bromacil in the most vulnerable area of
Florida and the restrictions on the use of bromacil in Pesticide Management Zones in California.
To further mitigate risk, DuPont has agreed to provide training materials to be used in
Certification and Training Programs.
Bromacil is also used in citrus-growing areas in Arizona and Texas but there is inadequate
monitoring information for these areas. The Agency is requiring DuPont to conduct additional
groundwater monitoring through a Data Call-in Notice to determine to what extent bromacil has
moved to groundwater. Details of this monitoring must be developed by the Agency and DuPont.
In pineapple production
Although bromacil is one of the principal herbicides used for postemergence weed control
for pineapple grown in Hawaii, the Agency does not believe there is unreasonable risk to the
quality of groundwater from its use. The average use on pineapples in Hawaii is relatively low
(4.8 Ib ai/A over four years) and is declining. It appears that the state is monitoring ground water
resources in pineapple areas, and bromacil has not been found in the groundwater. Therefore,
ground water risk mitigation is not needed for this use at this time.
Bromacil is also used in the U.S. territory of Puerto Rico for weed control in pineapple.
The Agency does not have information about the risk to groundwater for this use. Therefore, the
Agency has required an assessment of the vulnerability of the groundwater from DuPont.
In non-crop areas
Non-crop uses allow the highest rate of application of bromacil. However, bromacil use
comprises only 2-3 % of the area treated. Typical uses are to control vegetation on railroad
tracks, in and around electric power substations, and on roadsides. Application is usually made
in bands or confined to discrete areas. The historic use on ditch banks is no longer permitted.
As noted earlier, the maximum allowable rate has been reduced from 32 to 12 Ib ai/A for all uses
of bromacil, except for the use of bromacil as an undersurface treatment for toxic-waste holding
ponds, which will be allowed at up to the rate of 25 Ib ai/A.
9. Occupational Labeling Rationale/Risk Mitigation
The Agency examined results from the risk assessment and identified several scenarios for
which there currently are inadequate margins of exposure (MOEs < 100). Each of these
scenarios and the Agency's respective regulatory position is discussed below.
1. Mixing and loading wettable powder for groundboom application while wearing chemical
resistant gloves at the typical and maximum rates of application resulted in MOEs of 40 and 15,
respectively [scenario 1 (b) in Table 8].
2. Mixing and loading the dry flowable for groundboom application at the maximum rate using
gloves demonstrated an MOE of 83 [scenario Ic in Table 8].
67
-------
3. Mixing and loading the dry flowable for aerial application at the typical and the maximum
rates of application while wearing gloves resulted in MOEs of 19 and 51, respectively [scenario
1 (d) in Table 8].
4. Applying bromacil using the rights-of-way sprayer at the maximum rate without gloves
resulted in an MOE of 41 [scenario 2 (a) in Table 8].
5. Applying bromacil to the toxic-waste holding pond liner site at the maximum rate of 25 Ib
a.i./acre to the maximum area of 48 acres resulted in an MOE of 11.8 [scenario 2(b)].
6. Applying using a low pressure handwand at both the typical and maximum application rates
without gloves yielded MOEs of 13.3 and 4.9 respectively [scenario 6 in Table 8].
7. Mixing, loading and applying using the whirly bird spreader at the maximum rate without
gloves resulted in an MOE of 91 [scenario 8 in Table 8].
The worker risk assessment was made using the best available data and according to the
Agency's current policies, however, the Agency believes this assessment may be overly
conservative for several reasons. First, a study conducted by the oral route of exposure was used
to estimate risk from all routes of exposure including dermal and inhalation, as well as oral.
Second, the NOEL selected from this oral study was based on a minimal effect demonstrated
during only the first two days of dosing, suggesting that the actual NOEL level is likely to be
considerably higher than the 20 mg/kg/day selected. Third, a preliminary report from a 28-day
dermal study being conducted voluntarily by DuPont suggests that the NOEL may actually be an
order of magnitude greater than the 20 mg/kg/day selected. And lastly, dermal absorption was
estimated to be 20 percent based on a study that suggested much lower dermal absorption.
Because of this uncertainty in estimating risk to workers, DuPont voluntarily initiated a
28 day toxicity study by the dermal route of exposure. This study more closely characterizes the
main worker exposure to bromacil than data now available. Once this study is submitted, the
Agency will determine whether additional mitigation is required. Because preliminary reports
from this study indicate the MOE will likely be an order of magnitude greater than the current
NOEL of 20 mg/kg/day, the Agency expects most MOEs to no longer be of concern.
For scenario 1 (b) a significant portion (about half) of the exposure from this use is from
inhalation of the powder. Chemical resistant gloves reduce dermal but not inhalation exposure.
To further mitigate risk the Agency considered requiring water soluble packaging to reduce
exposure from both routes of exposure. However, this would require reformulation of bromacil-
containing products. Because of the uncertainty in the risk assessment, the Agency will consider
the results of the 28-day dermal toxicity study before imposing this requirement. During the
interim, to reduce exposure from the inhalation route, the Agency is requiring that a dust mask
be worn during the mixing and loading of wettable powder formulations of bromacil. Chemical-
resistant gloves remain as a requirement.
68
-------
For scenarios 2(a), 6, and 8, MOEs are acceptable with gloves even under this current
conservative risk assessment. In addition, MOEs for scenarios l(a) and 3 from Table 8, which
were not of concern, were calculated assuming that gloves were worn since current labels require
chemical resistant gloves be worn. Therefore, this requirement will remain in effect.
For scenario 2(b), the MOE is acceptable for the typical size of treated area (5 acres).
Therefore, unless the 28 day dermal study relieves concern for application beyond 5 acres, the
Agency will require the restriction that only 5 acres be treated per day.
Although scenario l(c) has an inadequate MOE of 83, the Agency believes that this is an
overly conservative estimate and that the true risk is likely to be at acceptable levels. No
additional protection is being required.
Scenario l(d) is mixing and loading for aerial application. This is confined to one use, the
control of brush on firing ranges in the Department of Defense Yakima Firing Center. The MOE
of concern at the maximum rate is 19. This MOE may change to an acceptable level with new
dermal toxicity information. However, because this use is very limited, applicators are trained,
and the benefits are high since it is used to control fires, the Agency believes the estimated risk
to be not unreasonable.
In conclusion, these above measures reduce risk to applicators to levels considered
acceptable by the Agency. However, these requirements may be revisited following submission
and review of the 28-day dermal study.
10. Worker Protection Standard
a. Scope of the WPS
The 1992 Worker Protection Standard for Agricultural Pesticides (WPS) established certain
worker-protection requirements (personal protective equipment, restricted-entry intervals, etc.)
to be specified on the label of all products that contain uses within the scope of the WPS. Uses
within the scope of the WPS include all commercial (non-homeowner) and research uses on farms,
forests, nurseries, and greenhouses to produce agricultural plants (including food, feed, and fiber
plants, trees, turf grass, flowers, shrubs, ornamental, and seedlings).
At this time, some of the uses of bromacil are within the scope of the Worker Protection
Standard for Agricultural Pesticides (WPS). Uses of bromacil that are outside the scope of the
WPS are those that are not directly related to the production of agricultural plants, including,
control of vegetation along rights-of-way, in industrial areas, around power stations, in drainage
systems, under toxic-waste holding-ponds, in recreation areas, and in other noncrop areas.
69
-------
b. Personal Protective Equipment/Engineering Controls for Handlers
For each end-use product, PPE requirements for pesticide handlers are set during
reregistration in one of two ways:
1. If EPA determines that no regulatory action must be taken as the result of the acute effects or
other adverse effects of an active ingredient, the PPE for pesticide handlers will be based on the
acute toxicity of the end-use product. For occupational-use products, PPE must be established
using the process described in PR Notice 93-7 or more recent EPA guidelines.
2. If EPA determines that regulatory action on an active ingredient must be taken as the result of
very high acute toxicity or to certain other adverse effects, such as allergic effects or delayed
effects (cancer, developmental toxicity, reproductive effects, etc.):
• In the RED for that active ingredient, EPA may establish minimum or "baseline" handler
PPE requirements that pertain to all or most end-use products containing that active
ingredient.
• These minimum PPE requirements must be compared with the PPE that would be
designated on the basis of the acute toxicity of the end-use product.
• The more stringent choice for each type of PPE (i.e., bodywear, hand protection,
footwear, eyewear, etc.) must be placed on the label of the end-use product.
Personal protective equipment requirements usually are set by specifying one or more pre-
established PPE units — sets of items that are almost always required together. For example, if
chemical-resistant gloves are required, then long-sleeve shirts, long pants, socks, and shoes are
assumed and are also included in the required minimum attire. If the requirement is for two
layers of body protection (coveralls over a long- or short-sleeve shirt and long or short pants), the
minimum must also include (for all handlers) chemical-resistant footwear and chemical-resistant
headgear for overhead exposures and (for mixers, loaders, and persons cleaning equipment)
chemical-resistant aprons.
Occupational-Use Products
EPA has determined that regulatory action regarding the establishment of active-ingredient-
based minimum PPE requirements for some occupational handlers must be taken for bromacil
based on the outcome of the occupational exposure/risk assessment discussed in Chapter IIIB2.
In all scenarios, the MOE's for dermal exposure are a problem for occupational mixers and
loaders involved in applications where groundboom, aerial, or power (rights-of-way) sprayers
are used unless chemical-resistant gloves are worn. Even with chemical resistant gloves, three
of these scenarios, the mixing and loading of wettable powders and dry flowables for groundboom
application, and dry flowables for aerial application resulted in MOEs of concern (15 to 83). To
mitigate this risk, the Agency considered requiring repackaging of this formulation into water
soluble bags. Instead, the Agency decided to require the use of a chemical resistant gloves, and
in the case of the wettable powder, a dust mask, until new information on toxicity is submitted
70
-------
(a 28 day dermal toxicity study). The Agency will reassess the risk once the 28-day dermal
toxicity study can be evaluated. This decision is partly based on the uncertainty about the actual
maternal NOEL in the rat developmental study, a key variable in the calculation of the MOE. In
summary, EPA is requiring active-ingredient based protection for handlers of bromacil in all these
exposure situations.
WPS and NonWPS Uses:
Since potential handler exposure is similar for uses in the scope of and outside the scope
of WPS, there is only one set of active-ingredient-based minimum (baseline) PPE or engineering
controls requirements for occupational uses of bromacil (specified in Section V). These
requirements must be followed in the labeling of all bromacil end-use products intended primarily
for occupational use.
Homeowner-Use Products
There are no homeowner uses of bromacil.
c. Occupational-Use Products (uses in the scope of WPS)
Post-Application/Entry Restrictions
Restricted-Entry Interval:
Under the Worker Protection Standard (WPS), interim restricted-entry intervals (REI's)
for all uses within the scope of the WPS are based on the acute toxicity of the active ingredient.
The toxicity categories of the active ingredient for acute dermal toxicity, eye irritation potential,
and skin irritation potential are used to determine the interim WPS REI. If one or more of the
three acute toxicity effects are in toxicity category I, the interim WPS REI is established at 48
hours. If none of the acute toxicity effects are in category I, but one or more of the three is
classified as category II, the interim WPS REI is established at 24 hours. If none of the three acute
toxicity effects are in category I or II, the interim WPS REI is established at 12 hours. In
addition, the WPS specifically retains two types of REI's established by the Agency prior to the
promulgation of the WPS: (1) product-specific REI's established on the basis of adequate data,
and (2) interim REI's that are longer than those that would be established under the WPS.
During the reregistration process, EPA considers all relevant product-specific information
to decide whether there is reason to shorten or lengthen the previously established REI.
The historic WPS REI in effect is 24 hours for the lithium salt of bromacil and 12 hours
for bromacil. This was an interim REI placed on bromacil products by PR Notice 93-7. EPA
notes that the 24-hour interim WPS REI was established on the lithium salt because data indicated
that the lithium salt was in toxicity category II for eye irritation potential. The 12-hour interim
71
-------
WPS REI was established for bromacil because data indicated that bromacil was in toxicity
category III/IV for acute dermal toxicity, skin irritation potential, and eye irritation potential.
Since bromacil is generally directed at the target weeds, contact with treated surfaces is
likely to be limited mostly to feet, lower legs, and, in some circumstances, hands. In considering
the risk from post-application exposures, EPA notes that the toxicological endpoint is based upon
a developmental toxicity study in rats in which the maternal NOEL was established at 20
mg/kg/day and the maternal LOEL at 75 mg/kg/day. The maternal effect noted was a minimal
effect involving decreases in body wight gain and food consumption during only the first two days
of dosing Thus, the actual maternal NOEL level is likely to be considerably higher than 20
mg/kg/day. It is further noted that both the maternal and developmental NOELs in the rabbit
study were established at a higher dose level, 100 mg/kg/day. Consideration of the minimal,
transitory effects noted at the rat maternal LOEL (75 mg/kg/day), the much higher dose (200
mg/kg/day) required to elicit pronounced developmental effects, and the likelihood of relatively
low post-application exposures, leads to a conclusion that the risks from post-application
exposures are likely to be acceptable as long as entry does not occur immediately following
application. Therefore, the REI remains at 24-hours or 12-hours for all occupational-use products
that contain the lithium salt of bromacil or bromacil respectively and are within the scope of the
Worker Protection Standard for Agricultural Pesticides (WPS).
Non-WPS scope Uses
The 12- or 24-hour post-application entry restriction for bromacil does not apply to uses
outside the scope of the WPS. The predicted frequency, duration, and degree of exposure related
to such uses do not warrant the same risk mitigation measures as are required for users covered
by the WPS. The Agency has determined that such post-application exposures do not appear to
pose an unreasonable risk to persons entering treated areas, as long as entry is not permitted
immediately after application.
For nonWPS occupational uses, the Agency is requiring:
• for liquid applications — a prohibition on entry until sprays have dried,
• for granular, dust, and other dry applications — a prohibition on entry until dusts
have settled.
Early-Entry PPE:
The WPS establishes very specific restrictions on entry by workers to areas that remain
under a restricted-entry interval, if the entry involves contact with treated surfaces. Among those
restrictions are a prohibition of routine entry to perform hand labor tasks and a requirement that
personal protective equipment be worn. Under the WPS, these personal protective equipment
requirements for persons who must enter areas that remain under a restricted-entry interval are
based on the acute toxicity category of the active ingredient.
72
-------
During the reregistration process, EPA considers all relevant product-specific information
to decide whether there is reason to set personal protective equipment requirements that differ
from those set through the WPS.
The RED requirements for early-entry personal protective equipment are set in one of two
ways:
1. If EPA determines that no regulatory action must be taken as the result of the acute effects
or other adverse effects of an active ingredient, it establishes the early-entry PPE
requirements on the basis of the acute dermal toxicity category, skin irritation potential
category, and eye irritation potential category of the active ingredient.
2. If EPA determines that regulatory action on an active ingredient must be taken as the result
of very high acute toxicity or to certain other adverse effects, such as allergic effects or
delayed effects (cancer, developmental toxicity, reproductive effects), it may establish
early-entry PPE requirements that are more stringent than would be established otherwise.
EPA is establishing early-entry PPE for dermal protection on the basis of the acute toxicity
of the active ingredient. Since bromacil is classified as toxicity category IV for acute dermal
toxicity and toxicity category IV for skin irritation potential, PPE for dermal protection required
for early entry is the minimum early-entry PPE permitted under the WPS. Since bromacil is
classified as toxicity category III for eye irritation potential, no protective eyewear is required.
However, since the lithium salt of bromacil is classified as toxicity II for eye irritation potential,
protective eyewear is required for the lithium salt of bromacil.
WPS Notification Statement:
Under the WPS, the labels of some pesticide products require employers to notify workers
about pesticide-treated areas orally as well as by posting of the treated areas. The reregistration
process also may decide that a product requires this type of "double notification." EPA has
determined that double notification is not required for bromacil end-use products.
Occupational-Use Products (NonWPS Uses)
EPA is establishing entry restrictions for all nonWPS occupational uses of bromacil end-
use products. For specific requirements, refer to Section V of this document.
73
-------
Homeowner-Use Products
At this time there are no end-use products intended primarily for homeowner use.
Other Labeling Requirements
The Agency is also requiring other use and safety information to be placed on the labeling
of all end-use products containing bromacil. For the specific labeling statements, refer to Section
V of this document.
11. Aerial Application
The Special Local Need registration for the state of Washington, WA93000200, allows
aerial application to control weeds on the Yakima Firing Center to prevent fires. Aerial
application is being allowed for this specific use because ground application is dangerous and
slow.
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 bromacil for the above eligible uses
has been reviewed and determined to be substantially complete. The following studies are
required to be conducted on the generic active ingredient.
Avian Reproduction Quail [71-4 (a)].
Avian Reproduction Duck [71-4 (b)].
Early Life-Stage Fish [72-4(a)].
Life-Cycle Aquatic Invertebrate [72-4(b)].
Dermal toxicity study[82-2].
Groundwater monitoring studies [166-1]
2. Additional Monitoring of Groundwater
The Agency is requiring monitoring of groundwater in citrus growing areas to establish
to what extent groundwater quality is being impacted. The Agency will work with DuPont to
establish a monitoring program.
74
-------
Normal agricultural use of bromacil has lead to ground-water contamination in the Central
Ridge of Florida and in certain areas of California as demonstrated by monitoring data. For these
areas, certain mitigation measures have been taken to reduce risk to water resources. The Agency
is also concerned with risk to groundwater in other citrus-growing areas where bromacil is used.
The Agency believes that it is appropriate to take additional precautions to ensure that the
quality of ground-water resources is not degraded. The Agency recommends that benchmarks (or
triggers), that are based on monitoring data, be established before widespread groundwater
contamination occurs. These benchmarks should clarify the kinds of actions that a registrant will
take to mitigate and better manage the use of the pesticide, as well as to define the circumstances
under which the use of the pesticide would require additional regulatory action .
B. Applicator Training Material
DuPont has agreed to provide material to be used in the Certification and Training
Program.
C. Vulnerability assessment for Groundwater in pineapple production areas of
Puerto Rico
DuPont is required to provide an assessment of the vulnerability of the groundwater to
bromacil contamination in pineapple production areas in Puerto Rico.
D. 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
The labels and labeling of all products must comply with EPA's current regulations and
requirements as specified in 40 CFR §156.10 and other applicable notices.
75
-------
PPE/Engineering Control Requirements for Pesticide Handlers
For sole-active-ingredient end-use products that contain bromacil, the product labeling
must be revised to adopt the handler personal protective equipment/engineering control
requirements set forth in this section. Any conflicting PPE requirements on the current labeling
must be removed.
For multiple-active-ingredient end-use products that contain bromacil, the handler
personal protective equipment/engineering control requirements set forth in this section must be
compared to the requirements on the current labeling and the more protective must be retained.
For guidance on which requirements are considered more protective, see PR Notice 93-7.
Products Intended Primarily for Occupational Use (WPS and nonWPS)
Minimum (Baseline) PPE Control Requirements
The Agency generally sets the minimum baseline PPE control requirements for pesticides
based on results from the risk assessment (Chapter 4).
EPA is establishing minimum (baseline) personal protective equipment (PPE) requirements
for some occupational uses of bromacil end-use products. The following is the minimum
(baseline) PPE for all occupational uses of bromacil end-use products formulated as a liquid,
wettable powder, or dry flowable:
"Applicators and other handlers must wear:
— long-sleeved shirt and long pants,
— chemical-resistant gloves*, and
— shoes plus socks."
In addition, while mixing and loading the wettable powder formulation, pesticide handlers
are required to wear a dust mask.
* For the glove statement, use the statement established for bromacil through the
instructions in Supplement Three of PR Notice 93-7.
EPA is not establishing minimum (baseline) personal protective equipment (PPE)
requirements for bromacil end-use products formulated as granules and pellets.
76
-------
Determining PPE Requirements for End-use Product Labels
The PPE that would be established on the basis of the acute toxicity category of the end-
use product must be compared to the active-ingredient-based minimum (baseline) personal
protective equipment specified above. The more protective PPE must be placed on the product
labeling. For guidance on which PPE is considered more protective, see PR Notice 93-7.
Placement in Labeling
The personal protective equipment requirements must be placed on the end-use product
labeling in the location specified in PR Notice 93-7, and the format and language of the PPE
requirements must be the same as is specified in PR Notice 93-7.
Entry Restrictions
For sole-active-ingredient end-use products that contain bromacil the product labeling
must be revised to adopt the entry restrictions set forth in this section. Any conflicting entry
restrictions on the current labeling must be removed.
For multiple-active-ingredient end-use products that contain bromacil the entry
restrictions set forth in this section must be compared to the entry restrictions on the current
labeling and the more protective must be retained. A specific time period in hours or days is
considered more protective than "sprays have dried" or "dusts have settled."
Products Intended Primarily for Occupational Use
WPS Uses
Restricted-entry interval:
A 24-hour restricted-entry interval (REI) is required for uses within the scope of the WPS
on all lithium-salt bromacil end-use products.
A 12-hour restricted-entry interval (REI) is required for uses within the scope of the WPS
on all other (non-lithium-salt) bromacil end-use products.
Early-entry personal protective equipment (PPE):
The PPE required for early entry is:
— coveralls,
— chemical-resistant gloves, and
— shoes plus socks.
77
-------
For the lithium salt of bromacil, protective eyewear also is required.
Placement in labeling:
The REI must be inserted into the standardized REI statement required by Supplement
Three of PR Notice 93-7. The PPE required for early entry must be inserted into the standardized
early-entry PPE statement required by Supplement Three of PR Notice 93-7.
NonWPS uses
Entry restrictions:
The Agency is establishing the following entry restrictions for nonWPS occupational uses
of bromacil end-use products:
For liquid applications:
"Do not enter or allow others to enter the treated area until sprays have dried."
For dry applications:
"Do not enter or allow others to enter the treated area until dusts have settled."
Placement in labeling:
If WPS uses are also on label — Follow the instructions in PR Notice 93-7 for establishing a
Non-Agricultural Use Requirements box, and place the appropriate nonWPS entry restrictions in
that box.
If no WPS uses are on the label — Place the appropriate nonWPS entry restrictions in the
Directions for Use, under the heading "Entry Restrictions."
Other Labeling Requirements
Products Intended Primarily for Occupational Use
The Agency is requiring the following labeling statements to be located on all end-use
products containing bromacil that are intended primarily for occupational use.
Application Restrictions
"Do not apply this product in a way that will contact workers or other persons,
either directly or through drift. Only protected handlers may be in the area during
application."
78
-------
Engineering Controls
"When handlers use closed systems (including water-soluble packets), enclosed
cabs, or aircraft in a manner that meets the requirements listed in the Worker
Protection Standard (WPS) for agricultural pesticides (40 CFR 170.240(d) (4-6),
the handler PPE requirements may be reduced or modified as specified in the
WPS."
User Safety Requirements
1. Registrants: place the following statement on the labeling if coveralls are required for
pesticide handlers on the end-use product label:
"Discard clothing or other absorbent materials that have been drenched or heavily
contaminated with this product's concentrate. Do not reuse them."
2. Registrants always place the following statement on the end-use product labeling:
"Follow manufacturer's instructions for cleaning/maintaining PPE. If no such instructions
for washables, use detergent and hot water. Keep and wash PPE separately from other
laundry."
User Safety Recommendations
• "Users should wash hands before eating, drinking, chewing gum, using tobacco, or using
the toilet."
• "Users should remove clothing immediately if pesticide gets inside. Then wash
thoroughly and put on clean clothing."
• "Users should remove PPE immediately after handling this product. Wash the outside of
gloves before removing. As soon as possible, wash thoroughly and change into clean
clothing."
Skin Sensitizer Statement
"This product may cause skin sensitization reactions in some people."
Reduction in Maximum Label Rates
All registrants are required to reduce maximum allowed rates to 12 Ib ai/A. If the State
of Florida lifts the current ban of bromacil on the central ridge of Florida, the Agency will not
allow application of bromacil above the rate of 1.6 Ib ai/acre per year at that location to minimize
risk to groundwater.
79
-------
E. Restriction of total acres allowed to be treated for the Toxic-Waste Holding-
Pond Liner Treatment
DuPont is required to change labels for this use to restrict the daily acres allowed to be
treated to a maximum of five acres per day.
F. Reduction of maximum application rate to no more than 12 Ib ai/A for all uses
except the undersurface treatment for toxic-waste holding ponds.
All registrants are required to submit labels restricting the maximum application rate to
no more than 12 Ib ai/A per year except for the undersurface treatment for toxic-waste holding
ponds. In addition, registrants are required to drop rates on citrus in Texas from 6.4 to 2.4 Ib
ai/acre.
G. Specify timing of application.
Registrants must submit labels that specify the timing of the application.
H. Removal of Recreational Areas from labels.
Registrants must remove language that permits application to recreational areas.
Registrants must also include the statement "Not to be used in any recreational areas or in or
around homes." on their labels.
I. Maximum seasonal application rate.
Registrants must submit labels where the maximum seasonal rate on citrus has been
standardized between labels.
J. Removal of the Ditch-bank treatment
Registrants must remove the statement "It is permissible to treat the berm of ditches,
seasonally dry flood plains, deltas, marshes, swamps, bogs and transitional areas between upland
and lowland sites" from labels.
K. Appropriate Use Rate for Russian thistle and kochia
Registrants must specify appropriate rate of application for control of Russian thistle and
kochia so that applicators can target their application rates to adequately control these noxious
weeds and minimize risks from over-application.
80
-------
L. 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 bromacil and bromacil
lithium salt containing 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 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
as (19??), the Agency was unable to determine or estimate the date of the
document.
143
-------
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.

ISSUED BY THE AGENCY
Unless otherwise noted herein, this Data Call-In does not in any way supersede or change
the requirements of any previous Data Call-In(s), or any other agreements entered into with the
Agency pertaining to such prior Notice. Registrants must comply with the requirements of all
Notices to avoid issuance of a Notice of Intent to Suspend their affected products.
SECTION III. COMPLIANCE WITH REQUIREMENTS OF THIS NOTICE
III-A. SCHEDULE FOR RESPONDING TO THE AGENCY
The appropriate responses initially required by this Notice for product specific data must
be submitted to the Agency within 90 days after your receipt of this Notice. Failure to
adequately respond to this Notice within 90 days of your receipt will be a basis for issuing a
Notice of Intent to Suspend (NOIS) affecting your products. This and other bases for issuance of
NOIS due to failure to comply with this Notice are presented in Section IV-A and IV-B.
III-B. OPTIONS FOR RESPONDING TO THE AGENCY
155
-------
The options for responding to this Notice for product specific data are: (a) voluntary
cancellation, (b) agree to satisfy the product specific data requirements imposed by this notice or

A discussion of how to respond if you chose the Voluntary Cancellation option is
presented below. A discussion of the various options available for satisfying the product
specific data requirements of this Notice is contained in Section III-C. A discussion of options
relating to requests for data waivers is contained in Section III-D.
There are two forms that accompany this Notice of which, depending upon your
response, one or both must be used in your response to the Agency. These forms are the Data-
Call-in Response Form, and the Requirements Status and Registrant's Response Form,
Attachment 2 and Attachment 3. The Data Call-In Response Form must be submitted as part of
every response to this Notice. In addition, one copy of the Requirements Status and Registrant's
Response Form must be submitted for each product listed on the Data Call-in Response Form
unless the voluntary cancellation option is selected or unless the product is identical to another
(refer to the instructions for completing the Data Call-in Response Form in Attachment 2).
Please note that the company's authorized representative is required to sign the first page of the
Data Call-in Response Form and Requirements Status and Registrant's Response Form (if this
form is required) and initial any subsequent pages. The forms contain separate detailed
instructions on the response options. Do not alter the printed material. If you have questions or
need assistance in preparing your response, call or write the contact person (s) identified in
Attachment 1.
1. Voluntary Cancellation - You may avoid the requirements of this Notice by requesting
voluntary cancellation of your product(s) containing the active ingredient that is the subject of
this Notice. If you wish to voluntarily cancel your product, you must submit a completed Data
Call-In Response Form, indicating your election of this option. Voluntary cancellation is item
number 5 on the Data Call-In Response Form. If you choose this option, this is the only form
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.
2. Satisfying the Product Specific Data Requirements of this Notice There are various
options available to satisfy the product specific data requirements of this Notice. These options
are discussed in Section III-C of this Notice and comprise options 1 through 6 on the
Requirements Status and Registrant's Response Form and item numbers 7a and 7b on the Data
Call-In Response Form. Deletion of a use(s) and the low volume/minor use option are not valid
options for fulfilling product specific data requirements.
3. Request for Product Specific Data Waivers. Waivers for product specific data are
discussed in Section III-D of this Notice and are covered by option 7 on the Requirements Status
and Registrant's Response Form. If you choose one of these options, you must submit both
156
-------
forms as well as any other information/data pertaining to the option chosen to address the data
requirement.
III-C SATISFYING THE DATA REQUIREMENTS OF THIS NOTICE
If you acknowledge on the Data Call-In Response Form that you agree to satisfy the
product specific data requirements (i.e. you select item number 7a or 7b), 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
jointly (Cost Sharing)
(3) I have made offers to cost-share (Offers to Cost Share)
(4) 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 — If you choose to develop the required data it must be in
conformance with Agency deadlines and with other Agency requirements as referenced herein
and in the attachments. All data generated and submitted must comply with the Good
Laboratory Practice (GLP) rule (40 CFR Part 160), be conducted according to the Pesticide
Assessment Guidelines (PAG), and be in conformance with the requirements of PR Notice 86-5.
The time frames in the Requirements Status and Registrant's Response Form are the time
frames that the Agency is allowing for the submission of completed study reports. The noted
deadlines run from the date of the receipt of this Notice by the registrant. If the data are not
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
157
-------
request, the original deadline remains. Normally, extensions can be requested only in cases of
extraordinary testing problems beyond the expectation or control of the registrant. Extensions
will not be given in submitting the 90-day responses. Extensions will not be considered if the
request for extension is not made in a timely fashion; in no event shall an extension request be
considered if it is submitted at or after the lapse of the subject deadline.
Option 2, Agreement to Share in Cost to Develop Data — Registrants may only choose
this option for acute toxicity data and certain efficacy data and only if EPA has indicated in the
attached data tables that your product and at least one other product are similar for purposes of
depending on the same data. If this is the case, data may be generated for just one of the
products in the group. The 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. If you
choose to enter into an agreement to share in the cost of producing the required data but will not
be submitting the data yourself, you must provide the name of the registrant who will be
submitting the data. You must also provide EPA with documentary evidence that an agreement
has been formed. Such evidence may be your letter offering to join in an agreement and the
other registrant's acceptance of your offer, or a written statement by the parties that an
agreement exists. The agreement to produce the data need not specify all of the terms of the
final arrangement between the parties or the mechanism to resolve the terms. Section 3(c)(2)(B)
provides that if the parties cannot resolve the terms of the agreement they may resolve their
differences through binding arbitration.
Option 3, Offer to Share in the Cost of Data Development — This option only applies to
acute toxicity and certain efficacy data as described in option 2 above. If you have made an
offer to pay in an attempt to enter into an agreement or amend an existing agreement to meet the
requirements of this Notice and have been unsuccessful, you may request EPA (by selecting this
option) to exercise its discretion not to suspend your registration(s), although you do not comply
with the data submission requirements of this Notice. EPA has determined that as a general
policy, absent other relevant considerations, it will not suspend the registration of a product of a
registrant who has in good faith sought and continues to seek to enter into a joint data
development/cost sharing program, but the other registrant(s) developing the data has refused to
accept your offer. To qualify for this option, you must submit documentation to the Agency
proving that you have made an offer to another registrant (who has an obligation to submit data)
to share in the burden of developing that data. You must also submit to the Agency a completed
EPA Form 8570-32, Certification of Offer to Cost Share in the Development of Data,
Attachment 7. In addition, you must demonstrate that the other registrant to whom the offer was
made has not accepted your offer to enter into a cost sharing agreement by including a copy of
your offer and proof of the other registrant's receipt of that offer (such as a certified mail
receipt). Your offer must, in addition to anything else, offer to share in the burden of producing
the data upon terms to be agreed or failing agreement to be bound by binding arbitration as
provided by FIFRA section 3(c)(2)(B)(iii) and must not qualify this offer. The other registrant
must also inform EPA of its election of an option to develop and submit the data required by this
Notice by submitting a Data Call-In Response Form and a Requirements Status and Registrant's
Response Form committing to develop and submit the data required by this Notice.
158
-------
In order for you to avoid suspension under this option, you may not withdraw your offer
to share in the burdens of developing the data. In addition, the other registrant must fulfill its
commitment to develop and submit the data as required by this Notice. If the other registrant
fails to develop the data or for some other reason is subject to suspension, your registration as
well as that of the other registrant will normally be subject to initiation of suspension
proceedings, unless you commit to submit, and do submit the required data in the specified time
frame. In such cases, the Agency generally will not grant a time extension for submitting the
data.
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(j) " 'raw data' means any laboratory worksheets,
records, memoranda, notes, or exact copies thereof, that are the result of original
observations and activities of a study and are necessary for the reconstruction and
evaluation of the report of that study. In the event that exact transcripts of raw
data have been prepared (e.g., tapes which have been transcribed verbatim,
dated, and verified accurate by signature), the exact copy or exact transcript may
be substituted for the original source as raw data. 'Raw data' may include
photographs, microfilm or microfiche copies, computer printouts, magnetic
media, including dictated observations, and recorded data from automated
instruments." The term "specimens", according to 40 CFR 160.3(k), means "any
material derived from a test system for examination or analysis."
b. Health and safety studies completed after May 1984 must also contain all GLP-
required quality assurance and quality control information, pursuant to the
requirements of 40 CFR Part 160. Registrants must also certify at the time of
submitting the existing study that such GLP information is available for post-May
1984 studies by including an appropriate statement on or attached to the study
signed by an authorized official or representative of the registrant.
159
-------
c. You must certify that each study fulfills the acceptance criteria for the Guideline
relevant to the study provided in the FIFRA Accelerated Reregistration Phase 3
Technical Guidance and that the study has been conducted according to the
Pesticide Assessment Guidelines (PAG) or meets the purpose of the PAG (both
available from NTIS). A study not conducted according to the PAG may be
submitted to the Agency for consideration if the registrant believes that the study
clearly meets the purpose of the PAG. The registrant is referred to 40 CFR
158.70 which states the Agency's policy regarding acceptable protocols. If you
wish to submit the study, you must, in addition to certifying that the purposes of
the PAG are met by the study, clearly articulate the rationale why you believe the
study meets the purpose of the PAG, including copies of any supporting
information or data. It has been the Agency's experience that studies completed
prior to January 1970 rarely satisfied the purpose of the PAG and that necessary
raw data are usually not available for such studies.
If you submit an existing study, you must certify that the study meets all requirements of
the criteria outlined above.
If you know of a study pertaining to any requirement in this Notice which does not meet
the criteria outlined above but does contain factual information regarding unreasonable adverse
effects, you must notify the Agency of such a study. If such study is in the Agency's files, you
need only cite it along with the notification. If not in the Agency's files, you must submit a
summary and copies as required by PR Notice 86-5.
Option 5, Upgrading a Study — If a study has been classified as partially acceptable and
upgradeable, you may submit data to upgrade that study. The Agency will review the data
submitted and determine if the requirement is satisfied. If the Agency decides the requirement is
not satisfied, you may still be required to submit new data normally without any time extension.
Deficient, but upgradeable studies will normally be classified as supplemental. However, it is
important to note that not all studies classified as supplemental are upgradeable. If you have
questions regarding the classification of a study or whether a study may be upgraded, call or
write the contact person listed in Attachment 1. If you submit data to upgrade an existing study
you must satisfy or supply information to correct all deficiencies in the study identified by EPA.
You must provide a clearly articulated rationale of how the deficiencies have been remedied or
corrected and why the study should be rated as acceptable to EPA. Your 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 should also be used to cite data that has been previously submitted to upgrade
a study, but has not yet been reviewed by the Agency. You must provide the MRID number of
the data submission as well as the MRID number of the study being upgraded.
160
-------
The criteria for submitting an existing study, as specified in Option 4 above, apply to all
data submissions intended to upgrade studies. Additionally your submission of data intended to
upgrade studies must be accompanied by a certification that you comply with each of those
criteria as well as a certification regarding protocol compliance with Agency requirements.
Option 6, Citing Existing Studies — If you choose to cite a study that has been previously
submitted to EPA, that study must have been previously classified by EPA as acceptable or it
must be a study which has not yet been reviewed by the Agency. Acceptable toxicology studies
generally will have been classified as "core-guideline" or "core minimum." For all other
disciplines the classification would be "acceptable." With respect to any studies for which you
wish to select this option you must provide the MRID number of the study you are citing and, if
the study has been reviewed by the Agency, you must provide the Agency's classification of the
study.
If you are citing a study of which you are not the original data submitter, you must
submit a completed copy of EPA Form 8570-31, Certification with Respect to Data
Compensation Requirements.
Registrants who select one of the above 6 options must meet all of the requirements
described in the instructions for completing the Data Call-in Response Form and the
Requirements Status and Registrant's Response Form, as appropriate.
III-D REQUESTS FOR DATA WAIVERS
If you request a waiver for 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 Requirements Status
and Registrant's Response Form. Product specific data requirements for product chemistry,
acute toxicity and efficacy (where appropriate) are required for all products and the Agency
would grant a waiver only under extraordinary circumstances. You should also be aware that
submitting a waiver request will not automatically extend the due date for the study in question.
Waiver requests submitted without adequate supporting rationale will be denied and the original
due date will remain in force.
IV. CONSEQUENCES OF FAILURE TO COMPLY WITH THIS NOTICE
IV-A NOTICE OF INTENT TO SUSPEND
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
161
-------
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
Notice.
5. Failure to take a required action or submit adequate information pertaining to any
option chosen to address the data requirements (e.g., any required action or
information pertaining to submission or citation of existing studies or offers,
arrangements, or arbitration on the sharing of costs or the formation of Task
Forces, failure to comply with the terms of an agreement or arbitration

failure of a registrant on whom you rely for a generic data exemption either to:
a. inform EPA of intent to develop and submit the data required by this
Notice on a Data Call-in Response Form and a Requirements Status and
Registrant's Response Form;
b. fulfill the commitment to develop and submit the data as required by this
Notice; or
c. otherwise take appropriate steps to meet the requirements stated in this
Notice, unless you commit to submit and do submit the required data in
the specified time frame.
9. Failure to take any required or appropriate steps, not mentioned above, at any
time following the issuance of this Notice.
162
-------
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 would generally not
be consistent with the Act's purposes. Accordingly, the Agency anticipates granting registrants
permission to sell, distribute, or use existing stocks of suspended product(s) only in exceptional
circumstances. If you believe such disposition of existing stocks of your product(s) which may
be suspended for failure to comply with this Notice should be permitted, you have the burden of
clearly demonstrating to EPA that granting such permission would be consistent with the Act.
You must also explain why an "existing stocks" provision is necessary, including a statement of
the quantity of existing stocks and your estimate of the time required for their sale, distribution,
and use. Unless you meet this burden the Agency will not consider any request pertaining to the
continued sale, distribution, or use of your existing stocks after suspension.
If you request a voluntary cancellation of your product(s) as a response to this Notice
and your product is in full compliance with all Agency requirements, you will have, under most
circumstances, one year from the date your 90 day response to this Notice is due, to sell,
distribute, or use existing stocks. Normally, the Agency will allow persons other than the
163
-------
registrant such as independent distributors, retailers and end users to sell, distribute or use such
existing stocks until the stocks are exhausted. Any sale, distribution or use of stocks of
voluntarily cancelled products containing an active ingredient for which the Agency has
particular risk concerns will be determined on case-by-case basis.
Requests for voluntary cancellation received after the 90 day response period required by
this Notice will not result in the Agency granting any additional time to sell, distribute, or use
existing stocks beyond a year from the date the 90 day response was due unless you demonstrate
to the Agency that you are in full compliance with all Agency requirements, including the
requirements of this Notice. For example, if you decide to voluntarily cancel your registration
six months before a 3 year study is scheduled to be submitted, all progress reports and other
information necessary to establish that you have been conducting the study in an acceptable and
good faith manner must have been submitted to the Agency, before EPA will consider granting
an existing stocks provision.
SECTION V. REGISTRANTS' OBLIGATION TO REPORT POSSIBLE
UNREASONABLE ADVERSE EFFECTS
Registrants are reminded that FIFRA section 6 (a) (2) states that if at any time after a
pesticide is registered a registrant has additional factual information regarding unreasonable
adverse effects on the environment by the pesticide, the registrant shall submit the information to
the Agency. Registrants must notify the Agency of any factual information they have, from
whatever source, including but not limited to interim or preliminary results of studies, regarding
unreasonable adverse effects on man or the environment. This requirement continues as long as
the products are registered by the Agency.
SECTION VI. INQUIRIES AND RESPONSES TO THIS NOTICE

EPA'S BATCHING OF BROMACIL PRODUCTS 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 Bromacil and Lithium Salt
of Bromacil as the active ingredients, the Agency has batched products which can be
considered similar for purposes 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. Notwith-standing 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 toxicological studies to represent all the products within that batch.
It is the registrants' option to participate in the process with all other registrants, only some of
the other registrants, or only their own products within a batch, or to generate all the required
acute toxicological studies for each of their own products. If a registrant chooses to generate
the data for a batch, he/she must use one of the products within the batch as the test material.
If a registrant chooses to rely upon previously submitted acute 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
179
-------
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.
One hundred and sixteen products were found which contain Bromacil or Lithium Salt of
Bromacil as the active ingredient. Ninty of these products contain Bromacil, and twenty six
contain Lithium salt of Bromacil. The products have been placed into 12 batches for Bromacil
and in 6 batches for Lithium salt of Bromacil in accordance with the active and inert
ingredients, type of formulation and current labeling. Table I identifies the products containing
Bromacil, Table II identifies products containing Lithium Salt of Bromacil, table III identifies
products that cannot be batched, and table 4 identifies products containing bromacil or the
lithium salt that have either been suspended or voluntarily withdrawn.
