Diflubenzuron; Pesticide Tolerances for Emergency Exemptions

AGENCY: Environmental Protection Agency (EPA).
ACTION: Final rule.

-----------------------------------------------------------------------

SUMMARY: This regulation establishes a time-limited tolerance for
diflubenzuron and its metabolites p-chlorophenylurea and p-
chloroaniline in or on lemon. This action is in response to EPA's
granting of an emergency exemption under section 18 of the Federal
Insecticide, Fungicide, and Rodenticide Act (FIFRA) authorizing use of
the pesticide on lemon. This regulation establishes a maximum
permissible level for combined residues of diflubenzuron and its
metabolites p-chlorophenylurea and p-chloroaniline, in this food
commodity. The tolerance expires and is revoked on December 31, 2010.

DATES: This regulation is effective July 25, 2007. Objections and
requests for hearings must be received on or before September 24, 2007,
and must be filed in accordance with the instructions provided in 40
CFR part 178 (see also Unit I.C. of the SUPPLEMENTARY INFORMATION.

II. Background and Statutory Findings

    EPA, on its own initiative, in accordance with sections 408(e) and
408(l)(6) of the Federal Food, Drug, and Cosmetic Act (FFDCA), 21
U.S.C. 346a, is establishing a tolerance for of the insecticide,
diflubenzuron and its metabolites p-chlorophenylurea and p-
chloroaniline, in or on lemon at 0.8 parts per million (ppm). This
tolerance expires and is revoked on December 31, 2010. EPA will publish
a document in the Federal Register to remove the revoked tolerance from
the Code of Federal Regulations (CFR).
    Section 408(l)(6) of the 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 section 18
of FIFRA. Such tolerances can be established without providing notice
or period for public comment. EPA does not intend for its actions on
section 18 related tolerances to set binding precedents for the
application of section 408 of the FFDCA and the new safety standard to
other tolerances and exemptions. Section 408(e) of the 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 the 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 the 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 the 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 the 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.'' This
provision was not amended by the Food Quality Protection Act of 1996
(FQPA). EPA has established regulations governing such emergency
exemptions in 40 CFR part 166.
    EPA is also revising the tolerance expression in Sec.  180.377(b)
to be consistent with the preferable wording as expressed in Sec. 
180.377(a)(2).

III. Emergency Exemption for Diflubenzuron on Lemon and FFDCA Tolerances

    In the fall of 2005 and spring of 2006, active infestations of
Diaprepes root weevil were detected including one lemon orchard (28
acres) in commercial sites in Long Beach, Newport Beach, Carlsbad,
Encintas, and La Jolla, California. The California Department of Food
and Agriculture (CDFA) has quarantined these sites and has already
initiated eradication treatments using products that impact various
life stages of this insect. The emergency use of diflubenzuron is
needed to treat the egg stage of the weevil when they are detected in
lemon. The overall program involves treatment for larval and adult
stages as well. EPA has authorized under FIFRA section 18 the use of
diflubenzuron on lemon for control of Diaprepes root weevil in
California. After having reviewed the submission, EPA concurs that
emergency conditions exist for this State.
    As part of its assessment of this emergency exemption, EPA assessed
the potential risks presented by residues of diflubenzuron in or on
lemon. In doing so, EPA considered the safety standard in section
408(b)(2) of the FFDCA, and EPA decided that the necessary tolerance
under section 408(l)(6) of the FFDCA 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 section 408(l)(6) of the FFDCA.
Although this tolerance expires and is revoked on December 31, 2007,
under section 408(l)(5) of the FFDCA, residues of the pesticide not in
excess of the amounts specified in the tolerance remaining in or on
lemon after that date will not be unlawful, provided the pesticide is
applied in a manner that was lawful under FIFRA, and the residues do
not exceed a level that was authorized by this tolerance at the time of
that application. EPA will take action to revoke this tolerance earlier
if any experience with, scientific data on, or other relevant
information on this pesticide indicate that the residues are not safe.
    Because this tolerance is being approved under emergency
conditions, EPA has not made any decisions about whether diflubenzuron
meets EPA's registration requirements for use on lemon or whether a
permanent tolerance for this use would be appropriate. Under these
circumstances, EPA does not believe that this tolerance serves as a
basis for registration of diflubenzuron by a State for special local
needs under FIFRA section 24(c). Nor does this tolerance serve as the
basis for any State other than California to use this pesticide on this
crop under section 18 of FIFRA without following all provisions of
EPA's regulations implementing FIFRA section 18 as identified in 40 CFR
part 166. For additional information regarding the emergency exemption
for diflubenzuron, contact the Agency's Registration Division at the
address provided under FOR FURTHER INFORMATION CONTACT.

IV. Aggregate Risk Assessment and Determination of Safety

    EPA performs a number of analyses to determine the risks from
aggregate exposure to pesticide residues. For further discussion of the
regulatory requirements of section 408 of the FFDCA and a complete
description of the risk assessment process, see 
http://www.epa.gov/fedrgstr/EPA-PEST/1997/November/Day-26/p30948.htm.
    Consistent with section 408(b)(2)(D) of the FFDCA, 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
diflubenzuron and to make a determination on aggregate exposure,
consistent with section 408(b)(2) of the FFDCA, for a time-limited
tolerance for combined residues of diflubenzuron in or on lemon at 0.8
ppm. EPA's assessment of the dietary exposures and risks associated
with establishing the tolerance follows.

A. Toxicological Endpoints

    For hazards that have a threshold below which there is no
appreciable risk, the dose at which no adverse effects are observed
(the NOAEL) from the toxicology study identified as appropriate for use
in risk assessment is used to estimate the toxicological level of
concern (LOC). However, the lowest dose at which adverse effects of
concern are identified (the LOAEL) is sometimes used for risk
assessment if no NOAEL was achieved in the toxicology study selected.
An uncertainty factor (UF) is applied to reflect uncertainties inherent
in the extrapolation from laboratory animal data to humans and in the
variations in sensitivity among members of the human population as well
as other unknowns.
    The linear default risk methodology (Q*) is the primary method
currently used by the Agency to quantify non-threshold hazards such as
cancer. The Q* approach assumes that any amount of exposure will lead
to some degree of cancer risk, estimates risk in terms of the
probability of occurrence of additional cancer cases. More information
can be found on the general principles EPA uses in risk
characterization at http://www.epa.gov/pesticides/health/human.htm. A
summary of the toxicological endpoints for diflubenzuron used for human
risk assessment is discussed in Unit III.B. of the final rule published
in the Federal Register of September 19, 2002 (67 FR 59006) (FRL-7200-4).

B. Exposure Assessment

    1. Dietary exposure from food and feed uses. Tolerances for
residues of diflubenzuron are established under 40 CFR 180.377.
Tolerances listed in 40 CFR 180.377(a)(1) are expressed in terms of
diflubenzuron per se. Under this section, tolerances of 0.05-6.0 ppm
are established for residues in/on eggs; milk; fat and meat of cattle,
goat, hog, horse, poultry, and sheep; poultry meat byproducts;
cottonseed; mushroom; grapefruit, orange (sweet); tangerine; soybean
hulls; and globe artichoke. Tolerances listed in 40 CFR 180.377(a)(2)
are expressed in terms of the combined residues of diflubenzuron and
its metabolites 4-chlorophenylurea (CPU) and 4-chloroaniline (PCA).
Under this section, tolerances of 0.02-55.0 pm are established for
residues in/on rice grain and straw; barley grain, straw, and hay; oat,
forage, grain, hay, and straw; wheat forage, grain, hay, and straw;
grain aspirated fractions; brassica, leafy greens, subgroup 5B; grass,
forage, fodder, and hay, group 17; tree nuts (group 14); peanut, peanut
hay and refined oil; pistachios; fruit, stone (group 12) except cherry;
meat byproducts of cattle, goat, hog, horse, and sheep; pear; pepper;
pummelo; turnip greens; and almond hulls. Time-limited tolerances
listed in 40 CFR 180.377(b) are expressed in terms of the combined
residues of diflubenzuron and its metabolites CPU and PCA, expressed as
the parent diflubenzuron, in connection with use of the pesticide under
Section 18 Emergency Exemptions granted by EPA. Risk assessments were
conducted by EPA to assess dietary exposures from diflubenzuron in food
as follows:
    i. Acute exposure. Acute dietary risk assessments are performed for
a food-use pesticide if a toxicological study has indicated the
possibility of an effect of concern occurring as a result of a 1-day or
single exposure. The diflubenzuron toxicology studies indicated no
possibility of such an effect for either the general U.S. population
(including infants and children) or the females 13-50 years old
population subgroup for diflubenzuron; therefore, an acute dietary
exposure analysis was not performed.
    ii. Chronic exposure. In conducting this chronic dietary risk
assessment the Dietary Exposure Evaluation Model (DEEM-FCID\TM\)
analysis evaluated the individual food consumption as reported by
respondents in the U.S. Department of Agriculture (USDA) 1994-1996 and
1998 Nationwide Continuing Surveys of Food Intake by Individuals
(CSFII) and accumulated exposure to the chemical for each commodity.
The following assumptions were made for the chronic exposure
assessments: A chronic dietary-exposure assessment was conducted using
the established/recommended tolerances for all food commodities, 100%
CT information for all proposed and existing uses, and DEEM(\TM\)
Version 7.81 default processing factors for some processed commodities.
    iii. Cancer. The Agency has classified diflubenzuron as ``Group
E,'' evidence of non-carcinogenicity for humans, based on lack of
evidence of carcinogenicity in rats and mice. There are also two
metabolites of diflubenzuron; PCA and CPU. PCA tested positive for
splenic tumors in male rats and hepatocellular adenomas/carcinomas in
male mice in a National Toxicology Program (NTP) study. Therefore, EPA
classified PCA as a ``Group B2'' probable human carcinogen. The Agency
determined for those commodities that contained PCA and CPU, the Q1* of
PCA should be used to calculate the cancer risk from the sum of these
two metabolites.
    Based on the submitted metabolism studies, there are two possible
sources for dietary exposure to PCA and CPU: Residues in mushrooms and
residues in milk and liver. Because human exposure to PCA and CPU will
not be affected by the proposed new uses, and EPA has previously
concluded that exposure to these compounds is safe, therefore, the
cancer dietary risk from PCA and CPU will not be addressed in this
document. For a detailed discussion on the exposure and risks to PCA and
CPU, please refer to the September, 2002 Federal Register document titled
Diflubenzuron; Pesticide Tolerances (September 19, 2002, FR 67 59006); 
http://www.epa.gov/fedrgstr/EPA-PEST/2002/September/Day-19/p23818.htm.
    2. Dietary exposure from drinking water. The Agency lacks
sufficient monitoring exposure data to assess dietary exposure to
diflubenzuron in drinking water based on measured drinking water
concentrations. Because the Agency does not have comprehensive
monitoring data, drinking water concentration estimates are made by
reliance on simulation or modeling taking into account data on the
physical characteristics of diflubenzuron. Further information
regarding EPA drinking water models used in pesticide exposure
assessment can be found at www.epa.gov/oppfed1/models/water/index.htm.
Based on the Pesticide Root Zone Model/Exposure Analysis

Modeling System (PRZM/EXAMS) and Screening Concentrations in Ground
Water (SCI-GROW) models, the estimated environmental concentrations
(EECs) of diflubenzuron and the major degradate CPU for chronic
exposures are estimated

[[Page 40757]]

to be 2.76 parts per billion (ppb) for surface water and 0.208 ppb for
ground water. Modeled estimates of drinking water concentrations were
directly entered into the dietary exposure model (DEEM-FCID\TM\,
Version 2.03). For chronic dietary risk assessment, the annual average
concentration of 2.76 ppb was used to represent the drinking water
contribution to chronic dietary exposure for diflubenzuron.
    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, and flea and tick control on pets). Although there are no
registered homeowner uses, there are registered uses for professional
applications to outdoor residential and recreational areas to control
mosquitoes, moths, and other insects. In addition, certain residential
use sites will be treated in association with this emergency exemption
for the control of the Diaprepes root weevil. However, EPA considers
the potential for post-application residential exposure to be low.
Further, diflubenzuron has a low dermal absorption rate (0.5%) and will
be only applied to the tree canopy.
    4. Cumulative effects from substances with a common mechanism of
toxicity. Section 408(b)(2)(D)(v) of the 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.''
    Unlike other pesticides for which EPA has followed a cumulative
risk approach based on a common mechanism of toxicity, EPA has not made
a common mechanism of toxicity finding as to diflubenzuron and any
other substances and diflubenzuron does not appear to produce a toxic
metabolite produced by other substances. For the purposes of this
tolerance action, therefore, EPA has not assumed that diflubenzuron has
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 the policy statements released by EPA's OPP concerning
common mechanism determinations and procedures for cumulating effects
from substances found to have a common mechanism on EPA's website at
http://www.epa.gov/pesticides/cumulative/.

C. Safety Factor for Infants and Children

    1. In general. Section 408 of the FFDCA provides that EPA shall
apply an additional tenfold 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 that a different margin of safety will be safe
for infants and children. Margins of safety are incorporated into EPA
risk assessments either directly through use of a MOE analysis or
through using uncertainty (safety) factors in calculating a dose level
that poses no appreciable risk to humans.
    2. Prenatal and postnatal sensitivity. Based on the developmental
and reproductive toxicity studies, there is no indication of increased
susceptibility of rats or rabbits to in utero or postnatal exposure.
    3. Conclusion. There is a complete toxicity database for
diflubenzuron and exposure data are complete or are estimated based on
data that reasonably accounts for potential exposures. EPA determined
that the additional FQPA 10X safety factor to protect infants and
children was not needed. This decision was based on the following:
    i. There is a complete toxicity database for diflubenzuron;
    ii. There is no indication of increased susceptibility of rats or
rabbits to in utero or postnatal exposure;
    iii. A developmental neurotoxicity study (DNT) with diflubenzuron
is not required;
    iv. Food and drinking water exposure assessments will not
underestimate the potential exposure for infants and children; and
    v. The potential for post-application residential exposures are
expected to be limited. Due to the low dermal absorption rate (0.5%) of
diflubenzuron, and since it is only applied to the tree canopy to
control gypsy moths and mosquitoes, minimal bystander contact is expected.

D. Aggregate Risks and Determination of Safety

    1. Acute risk. Because there were no toxic effects attributable to
a single dose of diflubenzuron, it 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 exposure to
diflubenzuron from food will utilize 12% of the cPAD for the U.S.
population, 12% of the cPAD for all infants less than 1 year old and
38% of the cPAD for children 1-2 years old. There are no residential
uses for diflubenzuron that result in chronic residential exposure to
diflubenzuron. EPA does not expect the aggregate exposure to exceed
100% of the cPAD.
    3. Short-term risk. Short-term aggregate exposure takes into
account residential exposure plus chronic exposure to food and water
(considered to be a background exposure level).
    The aggregate risk is the sum of the risk from food and water,
which do not exceed the Agency's LOC.
    4. Intermediate-term risk. Intermediate-term aggregate exposure
takes into account non-dietary, non-occupational exposure plus chronic
exposure to food and water (considered to be a background exposure level).
    The aggregate risk is the sum of the risk from food and water,
which do not exceed the Agency's LOC.
    5. Aggregate cancer risk for U.S. population. Based on the
available evidence, which included adequate carcinogenicity studies in
rats and mice, and battery of negative mutagenicity studies,
diflubenzuron has been classified as ``Group E,'' evidence of non-
carcinogenicity for humans, by the Agency. As noted in Unit
III.C.1.iii. of this document, the Agency has concluded that human
exposure to PCA and CPU (metabolites of diflubenzuron) will not be
affected by the proposed new uses. EPA has previously found aggregate
exposure to these compounds to be safe. (September 19, 2002, 67 FR 59006); 
http://www.epa.gov/fedrgstr/EPA-PEST/2002/September/Day-19/p23818.htm.
    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, and to infants and children from aggregate
exposure to diflubenzuron residues.

V. Other Considerations

A. Analytical Enforcement Methodology

    There are adequate enforcement methods, published in the Pesticide
Analytical Manual (PAM, Vol. II), for determining diflubenzuron
residues of concern. In addition, a new analytical methodology for
plant commodities was successfully validated by an independent
laboratory as well as by Agency chemists at the Analytical Chemistry
Branch (ACB)/Biological and Economics Analysis Division (BEAD) in
conjunction with an approved rice petition (PP 8F4925). The new methods
were forwarded to the Food and Drug Administration (FDA) for
publication in PAM Vol. II as Roman Numeral Methods. These methods can
separately determine residues of diflubenzuron by

[[Page 40758]]

gas chromatography/electron-capture detection (GC/ECD), CPU by GC/ECD,
and PCA by GC/mass spectrometry (MS).

B. International Residue Limits

    The Codex Alimentarius has established maximum residue limits
(MRL), expressed in terms of diflubenzuron per se, for many commodities
including: Apple (5 ppm), citrus fruits (0.5 ppm), edible offal
(mammalian) (0.1 ppm), eggs (0.05 ppm), meat (from mammals other than
marine mammals) (0.1 ppm), milks (0.02 ppm), mushrooms (0.3 ppm), pear
(5 ppm), pome fruits (5 ppm), poultry meat (0.05 ppm), rice (0.01 ppm),
and rice straw and fodder (dry) (0.7 ppm). As the U.S. residue
definition includes CPU and PCA, compatibility is not possible with the
proposed tolerance.

VI. Conclusion

    Therefore, the tolerance is established for of the insecticide
diflubenzuron, (N-[[(4-chlorophenyl)amino]carbonyl]-2,6-
difluorobenzamide and its metabolites 4-chlorophenylurea and 4-
chloroaniline in or on lemon at 0.8 ppm.

VII. Statutory and Executive Order Reviews

    This final rule establishes a tolerance under section 408(d) of
FFDCA in response to a petition submitted to the Agency. 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 rule has been
exempted from review under Executive Order 12866, this rule is not
subject to Executive Order 13211, 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 on the basis
of a petition under section 408(d) of FFDCA, such as the tolerance 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 section
408(n)(4) of FFDCA. 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 43255, August
10, 1999) and Executive Order 13175, entitled Consultation and
Coordination with Indian Tribal Governments (59 FR 22951, November 6,
2000) do not apply to this rule. In addition, This rule does not impose
any enforceable duty or contain any unfunded mandate as described under
Title II of the Unfunded Mandates Reform Act of 1995 (UMRA) (Public Law
104-4).
    This action does not involve any technical standards that would
require Agency consideration of voluntary consensus standards pursuant
to section 12(d) of the National Technology Transfer and Advancement Act

VIII. Congressional Review Act

    The Congressional Review Act, 5 U.S.C. 801 et seq., generally

the rule must submit a rule report to each House of the Congress and to
the Comptroller General of the United States. EPA will submit a report
containing this rule and other required information to the U.S. Senate,
the U.S. House of Representatives, and the Comptroller General of the
United States prior to publication of this final rule in the Federal
Register. This final rule is not a ``major rule'' as defined by 5
U.S.C. 804(2).
