II. Background and Statutory Findings
EPA, on its own initiative, in accordance with FFDCA sections
408(e) and 408(l)(6) of, 21 U.S.C. 346a(e) and 346a(1)(6), is
establishing time-limited tolerances for residues of fluridone, 1-
methyl-3-phenyl-5-(3-(trifluoromethyl)phenyl)-4(1H)-pyridinone, its
metabolites and degradates, in or on cotton, undelinted seed at 0.1
parts per million (ppm). These time-limited tolerances expire on
December 31, 2014.
Section 408(l)(6) of FFDCA requires EPA to establish a time-limited
tolerance or exemption from the requirement for a tolerance for
pesticide chemical residues in food that will result from the use of a
pesticide under an emergency exemption granted by EPA under FIFRA
section 18. Such tolerances can be established without providing notice
or period for public comment. EPA does not intend for its actions on
FIFRA section 18 related time-limited tolerances to set binding
precedents for the application of FFDCA section 408 and the safety
standard to other tolerances and exemptions. Section 408(e) of FFDCA
allows EPA to establish a tolerance or an exemption from the
requirement of a tolerance on its own initiative, i.e., without having
received any petition from an outside party.
Section 408(b)(2)(A)(i) of FFDCA allows EPA to establish a
tolerance (the legal limit for a pesticide chemical residue in or on a
food) only if EPA determines that the tolerance is ``safe.'' Section
408(b)(2)(A)(ii) of FFDCA defines ``safe'' to mean that ``there is a
reasonable certainty that no harm will result from aggregate exposure
to the pesticide chemical residue, including all anticipated dietary
exposures and all other exposures for which there is reliable
information.'' This includes exposure through drinking water and in
residential settings, but does not include occupational exposure.
Section 408(b)(2)(C) of FFDCA requires EPA to give special
consideration to exposure of infants and children to the pesticide
chemical residue in establishing a tolerance and to ``ensure that there
is a reasonable certainty that no harm will result to infants and
children from aggregate exposure to the pesticide chemical residue * *
*.''
Section 18 of FIFRA authorizes EPA to exempt any Federal or State
agency from any provision of FIFRA, if EPA determines that ``emergency
conditions exist which require such exemption.'' EPA has established
regulations governing such emergency exemptions in 40 CFR part 166.
III. Emergency Exemption for Fluridone on Cotton and FFDCA Tolerances
This is the first section 18 request received for the use of
fluridone on cotton. Since the introduction of glyphosate resistant
cotton in 1997, twenty-one weed species have developed resistance to
glyphosate. Glyphosate-resistant palmer amaranth is the most serious of
these species across all the major agronomic crops in the southern U.S.
Glyphosate-resistant palmer amaranth was confirmed in Arkansas in 2006.
Since 2006, it has become the most severe weed problem that Arkansas
cotton producers face. Greater than 95% of Arkansas cotton and 80% of
soybean contain the glyphosate tolerant gene and thus glyphosate is the
base herbicide for weed control. A significant economic loss is
expected to occur on nearly 25% of acres grown or about 160,000 acres.
After having reviewed the Arkansas emergency exemption application,
EPA determined that an emergency condition exists for this State, and
that the criteria for approval of an emergency exemption are met. EPA
has authorized a specific exemption under FIFRA section 18 for the use
of fluridone on cotton for control of glyphosate-resistant palmer
amaranth in Arkansas.
As part of its evaluation of the emergency exemption application,
EPA
[[Page 66717]]
assessed the potential risks presented by residues of fluridone in or
on cotton. In doing so, EPA considered the safety standard in FFDCA
section 408(b)(2), and EPA decided that the necessary tolerance under
FFDCA section 408(l)(6) would be consistent with the safety standard
and with FIFRA section 18. Consistent with the need to move quickly on
the emergency exemption in order to address an urgent non-routine
situation and to ensure that the resulting food is safe and lawful, EPA
is issuing this tolerance without notice and opportunity for public
comment as provided in FFDCA section 408(l)(6). Although these time-
limited tolerances expire on December 31, 2014, under FFDCA section
408(l)(5), residues of the pesticide not in excess of the amounts
specified in the tolerance remaining in or on cotton, undelinted seed
after that date will not be unlawful, provided the pesticide was
applied in a manner that was lawful under FIFRA, and the residues do
not exceed a level that was authorized by these time-limited tolerances
at the time of that application. EPA will take action to revoke these
time-limited tolerances earlier if any experience with, scientific data
on, or other relevant information on this pesticide indicate that the
residues are not safe.
Because these time-limited tolerances are being approved under
emergency conditions, EPA has not made any decisions about whether
fluridone meets FIFRA's registration requirements for use on cotton or
whether permanent tolerances for this use would be appropriate. Under
these circumstances, EPA does not believe that this time-limited
tolerance decision serves as a basis for registration of fluridone by a
State for special local needs under FIFRA section 24(c). Nor does this
tolerance by itself serve as the authority for persons in any State
other than Arkansas to use this pesticide on the applicable crops under
FIFRA section 18 absent the issuance of an emergency exemption
applicable within that State. For additional information regarding the
emergency exemption for fluridone, contact the Agency's Registration
Division at the address provided under FOR FURTHER INFORMATION CONTACT.
IV. Aggregate Risk Assessment and Determination of Safety
Section 408(b)(2)(A)(i) of FFDCA allows EPA to establish a
tolerance (the legal limit for a pesticide chemical residue in or on a
food) only if EPA determines that the tolerance is ``safe.'' Section
408(b)(2)(A)(ii) of FFDCA defines ``safe'' to mean that ``there is a
reasonable certainty that no harm will result from aggregate exposure
to the pesticide chemical residue, including all anticipated dietary
exposures and all other exposures for which there is reliable
information.'' This includes exposure through drinking water and in
residential settings, but does not include occupational exposure.
Section 408(b)(2)(C) of FFDCA requires EPA to give special
consideration to exposure of infants and children to the pesticide
chemical residue in establishing a tolerance and to ``ensure that there
is a reasonable certainty that no harm will result to infants and
children from aggregate exposure to the pesticide chemical residue * *
*.''
Consistent with the factors specified in FFDCA section
408(b)(2)(D), EPA has reviewed the available scientific data and other
relevant information in support of this action. EPA has sufficient data
to assess the hazards of, and to make a determination on, aggregate
exposure expected as a result of this emergency exemption request and
the time-limited tolerances for residues of fluridone on cotton,
undelinted seed at 0.1 ppm. EPA's assessment of exposures and risks
associated with establishing time-limited tolerances follows.
A. Toxicological Points of Departure/Levels of Concern
Once a pesticide's toxicological profile is determined, EPA
identifies toxicological points of departure (POD) and levels of
concern to use in evaluating the risk posed by human exposure to the
pesticide. For hazards that have a threshold below which there is no
appreciable risk, the toxicological POD is used as the basis for
derivation of reference values for risk assessment. PODs are developed
based on a careful analysis of the doses in each toxicological study to
determine the dose at which no adverse effects are observed (the NOAEL)
and the lowest dose at which adverse effects of concern are identified
(the LOAEL). Uncertainty/safety factors are used in conjunction with
the POD to calculate a safe exposure level--generally referred to as a
population-adjusted dose (PAD) or a reference dose (RfD)--and a safe
margin of exposure (MOE). For non-threshold risks, the Agency assumes
that any amount of exposure will lead to some degree of risk. Thus, the
Agency estimates non-threshold risk in terms of the probability of an
occurrence of the adverse effect expected in a lifetime. For more
information on the general principles EPA uses in risk characterization
and a complete description of the risk assessment process, see http://www.epa.gov/pesticides/factsheets/riskassess.htm.
A summary of the toxicological endpoints for fluridone used for
human risk assessment is shown in Table 1. of this unit.

B. Exposure Assessment
1. Dietary exposure from food and feed uses. In evaluating dietary
exposure to fluridone, EPA considered exposure under the time-limited
tolerances established by this action as well as all existing fluridone
tolerances in 40 CFR 180.420. EPA assessed dietary exposures from
fluridone in food as follows:
i. Acute exposure. Such effects were identified for fluridone. In
estimating acute dietary exposure for the subpopulation, females 13-49
years, EPA used food consumption information from the United States
Department of Agriculture (USDA) 1994-1996 and 1998 Nationwide
Continuing Surveys of Food Intake by Individuals (CSFII). As to residue
levels in food, EPA used tolerance level residues, DEEM (Ver. 7.81)
default processing factors (as necessary) and 100 percent crop treated
(PCT) for all commodities.
ii. Chronic exposure. In conducting the chronic dietary exposure
assessment EPA used the food consumption data from the USDA 1994-1996
and 1998 CSFII. As to residue levels in food, EPA used tolerance level
residues, DEEM (Ver. 7.81) default processing factors (as necessary)
and 100 PCT for all commodities.
iii. Cancer. Based on the data summarized in Unit IV.A., EPA has
concluded that fluridone does not pose a cancer risk to humans.
Therefore, a dietary exposure assessment for the purpose of assessing
cancer risk is unnecessary.
iv. Anticipated residue and PCT information. EPA did not use
anticipated residue or PCT information in the dietary assessment for
fluridone. Tolerance level residues and 100 PCT were assumed for all
food commodities.
2. Dietary exposure from drinking water. The Agency used screening
level water exposure models in the dietary exposure analysis and risk
assessment for fluridone in drinking water. These simulation models
take into account data on the physical, chemical, and fate/transport
characteristics of fluridone. Further information regarding EPA
drinking water models used in pesticide exposure assessment can be
found at http://www.epa.gov/oppefed1/models/water/index.htm.
Based on the FQPA Index Reservoir Screening Tool (FIRST) and
Screening Concentration in Ground Water (SCI-GROW) models, the
estimated drinking water concentrations (EDWCs) of fluridone for acute
exposures are estimated to be 9.6 parts per billion (ppb) for surface
water and 0.67 ppb for ground water. EDWCs of fluridone for chronic
exposures for non-cancer assessments are estimated to be 2.5 ppb for
surface water and 0.67 ppb for ground water.
Modeled estimates of drinking water concentrations were directly
entered into the dietary exposure model. For acute dietary risk
assessment, the water concentration value of 9.6 ppb was used to assess
the contribution to drinking water. For chronic dietary risk
assessment, the water concentration of value 2.5 ppb was used to assess
the contribution to drinking water.
3. From non-dietary exposure. The term ``residential exposure'' is
used in this document to refer to non-occupational, non-dietary
exposure (e.g., for lawn and garden pest control, indoor pest control,
termiticides, swimming in treated water, and flea and tick control on
pets).
Fluridone is currently registered for one use that could result in
residential handler and residential post-application exposures:
Consumer use to control aquatic weeds in ponds. EPA assessed
residential exposure using the following assumptions: Residents or
consumers may experience short-term (1-30 days) skin contact or
inhalation exposures. These exposures are assessed through residential
handler scenarios. Post-application exposures of children and adults
through contact with treated swimming ponds are also anticipated. These
exposures are expected to be short- and intermediate-term (1-6 months)
in duration through dermal, ingestion, aural, buccal/sublingual, and
nasal/orbital exposure. All residential handler and post-application
scenarios from the uses of fluridone have been assessed and no risks of
concern have been identified (MOE <=100). The scenarios for residential
handler and post-application exposure (combined dermal and inhalation)
resulted in MOEs of 1,800 and 23,000, respectively.
Further information regarding EPA standard assumptions and generic
inputs for residential exposures may be found at: http://www.epa.gov/pesticides/trac/science/trac6a05.pdf.
4. Cumulative effects from substances with a common mechanism of
toxicity. Section 408(b)(2)(D)(v) of FFDCA requires that, when
considering whether to establish, modify, or revoke a tolerance, the
Agency consider ``available information'' concerning the cumulative
effects of a particular pesticide's residues and ``other substances
that have a common mechanism of toxicity.''
EPA has not found fluridone to share a common mechanism of toxicity
with any other substances, and fluridone does not appear to produce a
toxic metabolite produced by other substances. For the purposes of this
tolerance action, therefore, EPA has assumed that fluridone does not
have a common mechanism of toxicity with other substances. For
information regarding EPA's efforts to determine which chemicals have a
common mechanism of toxicity and to evaluate the cumulative effects of
such chemicals, see EPA's Web site at
[[Page 66719]]
http://www.epa.gov/pesticides/cumulative.
C. Safety Factor for Infants and Children
1. In general. Section 408(b)(2)(C) of FFDCA provides that EPA
shall apply an additional tenfold (10X) margin of safety for infants
and children in the case of threshold effects to account for prenatal
and postnatal toxicity and the completeness of the database on toxicity
and exposure unless EPA determines based on reliable data that a
different margin of safety will be safe for infants and children. This
additional margin of safety is commonly referred to as the FQPA Safety
Factor (SF). In applying this provision, EPA either retains the default
value of 10X, or uses a different additional SF when reliable data
available to EPA support the choice of a different factor.
2. Prenatal and postnatal sensitivity. Based on the results in the
developmental toxicity studies in rats and rabbits and in a three-
generation reproduction study, no increased sensitivity of fetuses or
pups (as compared to adults) was demonstrated for fluridone. There are
no concerns or residual uncertainties for prenatal/postnatal toxicity
following exposure to fluridone.
3. Conclusion. EPA has determined that reliable data show that the
safety of infants and children would be adequately protected if the
FQPA SF were reduced to 1X. That decision is based on the following
findings:
i. The toxicity database for fluridone is complete except for the
lack of an immunotoxicity study and a neurotoxicity battery (i.e.,
acute and subchronic neurotoxicity) that meets the new data
requirements in 40 CFR part 158 for conventional pesticide
registration. However, the existing toxicology database for fluridone
does not show any evidence of treatment-related effects on either the
nervous or the immune system. In addition, fluridone does not belong to
any class of compounds (e.g., the organotins, heavy metals, or
halogenated aromatic hydrocarbons) that would be expected to be
immunotoxic. Based on the currently available data for fluridone, the
Agency expects that findings from the additional studies will not
result in a lower point of departure POD than that currently in use for
overall risk assessment, and therefore, a database uncertainty factor
is not needed to account for the lack of these studies.
ii. There is no indication that fluridone is a neurotoxic chemical
and there is no need for a developmental neurotoxicity study or
additional UFs to account for neurotoxicity.
iii. There is no evidence that fluridone results in increased
susceptibility in in utero rats or rabbits in the prenatal
developmental studies or in young rats in the 2-generation reproduction
study.
iv. There are no residual uncertainties identified in the exposure
databases. The dietary food exposure assessment utilized 100 PCT and
tolerance-level residues (established or recommended). EPA made
conservative (protective) assumptions in the ground and surface water
modeling used to assess exposure to fluridone in drinking water. EPA
used similarly conservative assumptions to assess post-application
exposure of children as well as incidental oral exposure of toddlers.
These assessments will not underestimate the exposure and risks posed
by fluridone.
D. Aggregate Risks and Determination of Safety
EPA determines whether acute and chronic dietary pesticide
exposures are safe by comparing aggregate exposure estimates to the
acute PAD (aPAD) and chronic PAD (cPAD). For linear cancer risks, EPA
calculates the lifetime probability of acquiring cancer given the
estimated aggregate exposure. Short-, intermediate-, and chronic-term
risks are evaluated by comparing the estimated aggregate food, water,
and residential exposure to the appropriate PODs to ensure that an
adequate MOE exists.
1. Acute risk. An acute aggregate risk assessment takes into
account acute exposure estimates from dietary consumption of food and
drinking water. An adverse effect resulting from a single oral exposure
was identified for only the subpopulation females 13-49 years. Using
the exposure assumptions described in this unit for acute exposure, EPA
has concluded that acute exposure to fluridone from food and water will
utilize less than 1% of the aPAD for females 13-49 years. Therefore,
fluridone is not expected to pose an acute risk.
2. Chronic risk. Using the exposure assumptions described in this
unit for chronic exposure, EPA has concluded that chronic exposure to
fluridone from food and water will utilize 4% of the cPAD for children
1-2 years, the population group receiving the greatest exposure. Based
on the explanation in the unit regarding residential use patterns,
chronic residential exposure to residues of fluridone is not expected.
3. Short-and Intermediate-term risk. Short- and intermediate-term
aggregate exposure takes into account short-term residential exposure
or intermediate-term residential exposure plus chronic exposure to food
and water (considered to be a background exposure level).
Fluridone is currently registered for uses that could result in
short- and intermediate-term residential exposure, and the Agency has
determined that it is appropriate to aggregate chronic exposure through
food and water with short- and intermediate-term residential exposures
to fluridone.
Using the exposure assumptions described in this unit for short-
term and intermediate-term exposures, EPA has concluded the combined
short-term food, water, and residential exposures and the intermediate-
term food, water, and residential exposures each result in aggregate
MOEs of 290 (liquids for pouring applications + swimming exposure) to
340 (liquids for garden hose end sprayer + swimming exposure). Because
EPA's level of concern for fluridone is a MOE of 100 or below, these
MOEs are not of concern.
5. Aggregate cancer risk for U.S. population. Based on the lack of
evidence of carcinogenicity in two adequate rodent carcinogenicity
studies, fluridone is not expected to pose a cancer risk to humans.
6. Determination of safety. Based on these risk assessments, EPA
concludes that there is a reasonable certainty that no harm will result
to the general population, or to infants and children, from aggregate
exposure to fluridone residues.
V. Other Considerations
A. Analytical Enforcement Methodology
Adequate enforcement methodologies (enzyme-linked immunosorbant
assay (ELISA), high performance liquid chromatography with ultraviolet
detection (HLPC/UV), and liquid chromatography with tandem mass
spectroscopy (LC-MSMS)) are available to enforce the tolerance
expression. The method may be requested from: Chief, Analytical
Chemistry Branch, Environmental Science Center, 701 Mapes Rd., Ft.
Meade, MD 20755-5350; telephone number: (410) 305-2905; email address:
residuemethods@epa.gov.
B. International Residue Limits
In making its tolerance decisions, EPA seeks to harmonize U.S.
tolerances with international standards whenever possible, consistent
with U.S. food safety standards and agricultural practices. EPA
considers the international maximum residue limits (MRLs) established
by the Codex Alimentarius Commission (Codex), as required by FFDCA
section 408(b)(4).
[[Page 66720]]
The Codex Alimentarius is a joint United Nations Food and Agriculture
Organization/World Health Organization food standards program, and it
is recognized as an international food safety standards-setting
organization in trade agreements to which the United States is a party.
EPA may establish a tolerance that is different from a Codex MRL;
however, FFDCA section 408(b)(4) requires that EPA explain the reasons
for departing from the Codex level. The Codex has not established an
MRL for fluridone.
VI. Conclusion
Therefore, time-limited tolerances are established for residues of
fluridone, 1-methyl-3-phenyl-5-(3-(trifluoromethyl)phenyl)-4(1H)-
pyridinone, including its metabolites and degradates, in or on cotton,
undelinted seed at 0.1 ppm. This tolerance expires on December 31,
2014.
VII. Statutory and Executive Order Reviews
This final rule establishes tolerances under FFDCA sections 408(e)
and 408(l)(6). The Office of Management and Budget (OMB) has exempted
these types of actions from review under Executive Order 12866,
entitled ``Regulatory Planning and Review'' (58 FR 51735, October 4,
1993). Because this final rule has been exempted from review under
Executive Order 12866, this final rule is not subject to Executive
Order 13211, entitled ``Actions Concerning Regulations That
Significantly Affect Energy Supply, Distribution, or Use'' (66 FR
28355, May 22, 2001) or Executive Order 13045, entitled ``Protection of
Children from Environmental Health Risks and Safety Risks'' (62 FR
19885, April 23, 1997). This final rule does not contain any
information collections subject to OMB approval under the Paperwork
Reduction Act (PRA), 44 U.S.C. 3501 et seq., nor does it require any
special considerations under Executive Order 12898, entitled ``Federal
Actions to Address Environmental Justice in Minority Populations and
Low-Income Populations'' (59 FR 7629, February 16, 1994).
Since tolerances and exemptions that are established in accordance
with FFDCA sections 408(e) and 408(l)(6), such as the tolerances in
this final rule, do not require the issuance of a proposed rule, the
requirements of the Regulatory Flexibility Act (RFA) (5 U.S.C. 601 et
seq.) do not apply.
This final rule directly regulates growers, food processors, food
handlers, and food retailers, not States or tribes, nor does this
action alter the relationships or distribution of power and
responsibilities established by Congress in the preemption provisions
of FFDCA section 408(n)(4). As such, the Agency has determined that
this action will not have a substantial direct effect on States or
tribal governments, on the relationship between the national government
and the States or tribal governments, or on the distribution of power
and responsibilities among the various levels of government or between
the Federal Government and Indian tribes. Thus, the Agency has
determined that Executive Order 13132, entitled ``Federalism'' (64 FR
