II. Background and Statutory Findings

    In the Federal Register of February 9, 1999 (64 FR 6351) (FRL-
6058-3), EPA issued a notice pursuant to section 408 of the Federal
Food, Drug, and Cosmetic Act (FFDCA), 21 U.S.C. 346a as amended by the
Food Quality Protection Act of 1996 (FQPA) (Public Law 104-170)
announcing the filing of pesticide petitions (PP) for tolerance by IR-
4. This notice included a summary of the petitions prepared by the Rohm
and Haas Company, the registrant. There were no comments received in
response to the notice of filing.
    The petitions requested that 40 CFR 180.482 be amended by
establishing tolerances for residues of the insecticide tebufenozide,
in or on turnip tops, turnip roots, canola seed, and refined canola oil
at 9.0, 0.25, 1.75, and 3.75 part per million (ppm), respectively. The
petitions were subsequently amended by IR-4 to propose tolerances for
turnip tops at 9.0 ppm, turnip roots at 0.3 ppm, canola seed at 2.0
ppm, and canola oil, refined at 4.0 ppm.
    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) 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)
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...."
    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 and a complete description of
the risk assessment process, see the final rule on Bifenthrin Pesticide
Tolerances (62 FR 62961, November 26, 1997) (FRL-5754-7).

III. Aggregate Risk Assessment and Determination of Safety

    Consistent with 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
tebufenozide and to make a determination on aggregate exposure,
consistent with section 408(b)(2), for tolerances for residues of
tebufenozide on turnip tops, turnip roots, canola seed, and refined
canola oil at 9.0, 0.3, 2.0, and 4.0 ppm, respectively. EPA's
assessment of the dietary exposures and risks associated with
establishing these tolerances follows.

A. Toxicological Profile

    EPA has evaluated the available toxicity data and considered its
validity, completeness, and reliability as well as the relationship of
the results of the studies to human risk. EPA has also considered
available information concerning the variability of the sensitivities
of major identifiable subgroups of consumers, including infants and
children. The nature of the toxic effects caused by tebufenozide are
discussed in unit II.A. of the Final rule on Tebufenozide Pesticide
Tolerances published in the Federal Register on April 7, 1999 (64 FR
16850) (FRL-6072-6).

B. Toxicological Endpoints

    The toxicology endpoints for tebufenozide are discussed in Unit
II.B. of the Final rule on Tebufenozide Pesticide Tolerances published
in the Federal Register of April 7, 1999.

C. Exposures and Risks

    1. From food and feed uses. Tolerances have been established (40
CFR 180.482) for the residues of tebufenozide, in or on a variety of
raw agricultural commodities. Canola meal and turnip tops are ruminant
feed item. Permanent tolerances for livestock commodities (excluding
poultry) were published in the Federal Register (64 FR 39060, July 21,
1999). Risk assessments were conducted by EPA to assess dietary
exposures from tebufenozide as follows:
    Section 408(b)(2)(F) states that the Agency may use data on the
actual percent of crop treated (PCT) for assessing chronic dietary risk
only if the Agency can make the following findings: That the data used
are reliable and provide a valid basis to show what percentage of the
food derived from such crop is likely to contain such pesticide
residue; that the exposure estimate does not underestimate exposure for
any significant subpopulation group; and if data are available on
pesticide use and food consumption in a particular area, the exposure
estimate does not understate exposure for the population in such area.
In addition, the Agency must provide for periodic evaluation of any
estimates used. To provide for the periodic evaluation of the estimate
of PCT as required by section 408(b)(2)(F), EPA may require registrants
to submit data on PCT.
    The Agency used PCT information as follows:
    Estimates of PCT were used for the following crops. In all cases
the maximum estimate was used. Almonds: average < 1% maximum < 1%,
apples: average 1% maximum 2%, beans/peas, dry: average 0% maximum 1%,
cotton: average 1% maximum 4%, sugarcane: average 3% maximum 5%, and
walnuts: average 10% maximum 16%.
    The Agency believes that the three conditions, discussed in section
408 (b)(2)(F) in this unit concerning the Agency's responsibilities in
assessing chronic dietary risk findings, have been met. The PCT
estimates are derived from Federal and private market survey data,
which are reliable and have a valid basis. Typically, a range of
estimates are supplied and the upper end of this range is assumed for
the exposure assessment. By using this upper end estimate of the PCT,
the Agency is reasonably certain that the percentage of the food
treated is not likely to be underestimated. The regional consumption
information and consumption information for significant subpopulations
is taken into account through EPA's computer-based model for evaluating
the exposure of significant subpopulations including several regional
groups. Use of this consumption information in EPA's risk assessment
process ensures that EPA's exposure estimate does not understate
exposure for any significant subpopulation group and allows the Agency
to be reasonably certain that no regional population is exposed to
residue levels higher than those estimated by the Agency. Other than
the data available through national food consumption surveys, EPA does not

[[Page 52459]]

have available information on the regional consumption of food to which
may be applied in a particular area.
    i. Acute exposure and risk. 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. Toxicity observed in oral toxicity
studies were not attributable to a single dose (exposure). No
neurological or systemic toxicity was observed in rats given a single
oral administration of tebufenozide at 0, 500, 1,000 or 2,000 mg/kg. No
maternal or developmental toxicity was observed following oral
administration of tebufenozide at 1,000 mg/kg/day (Limit-Dose) during
gestation to pregnant rats or rabbits. This risk assessment is not
required. The Agency considers acute exposure/risk to be negligible.
    ii. Chronic exposure and risk. The residue of concern for
tebufenozide in plant and animal commodities is the parent compound per
se. The chronic population adjusted dose (cPAD) used for the chronic
dietary analysis is 0.018 mg/kg/day. In performing chronic dietary
exposure and risk analysis, the Agency used the Dietary Exposure
Evaluation Model (DEEM), which incorporates data from the Continuing
Survey of Food Intake by Individuals (CSFII) for the period, 1989 to
1992. Some refinement to the dietary exposure estimates was made
through the use of percent-of-crop-treated data. The resulting
Anticipated Residue Contributions (ARC) for the U.S. population and
various DEEM population subgroups can be determined. Of these
subgroups, the highest exposure is projected for children ages 1-6
years, whose chronic intake is estimated as 73% of the cPAD. Percent
cPAD values for other subgroups include: U.S. Population for the 48
states (36%), all infants less than 1 yr. (52%), and children 7 to 12
yrs. (46%). Generally, in the absence of additional safety factors, the
Agency is not concerned with exposures less than 100% of the cPAD.
Thus, for all populations, the chronic human health risk from exposure
to tebufenozide in foods is below the Agency's level of concern.
    2. From drinking water. Available data suggest that tebufenozide
ranges from moderately persistent to persistent and is mobile; thus,
tebufenozide could potentially leach to ground water and runoff to
surface water under certain environmental conditions. There is no
Maximum Contaminant Level (MCL) for residues of tebufenozide in
drinking water. No drinking water Health Advisories have been issued
for tebufenozide. There is no entry for tebufenozide in the
"Pesticides in Groundwater Database (EPA 734-12-92-001, September
1992).
    i. Acute exposure and risk. Because no acute dietary endpoint was
determined, the Agency concludes that there is a reasonable certainty
of no harm from acute exposure from drinking water.
    ii. Chronic exposure and risk. Submitted environmental fate studies
suggest that tebufenozide ranges from moderately persistent to
persistent and is mobile; thus, tebufenozide could potentially leach to
ground water and runoff to surface water under certain environmental
conditions. There is no established MCL for residues of tebufenozide in
drinking water. No drinking water Health Advisories have been issued
for tebufenozide. There is no entry for tebufenozide in the
"Pesticides in Groundwater Database." Monitoring data are not
available to assess the human exposure to tebufenozide via drinking
water. In lieu of these, EPA has calculated the Tier I estimated
environmental concentrations in drinking water (EECs) for tebufenozide
using generic expected environmental concentration (GENEEC) (surface
water) and screening concentration in ground water (SCI-GROW) (ground
water) for use in the human health risk assessment. The maximum
application rate for tebufenozide is 0.25 pound (lb) active ingredient
(a.i.) with 5 applications per year on pecans. This application
scenario was used to calculate the EECs for the human health risk
assessment. Due to the wide range of aerobic soil half-life values,
GENEEC and SCIGROW were run based on aerobic half-lives of 66
(California Loam) and 729 (worst-case soil with low microbial activity)
days. For surface water, the chronic (56-day) values are 13.3 parts per
billion (ppb) and 16.5 ppb for the half-lives of 66 and 729 days,
respectively. The ground water screening concentrations are 0.16 ppb
and 1.04 ppb for the half-lives of 66 and 729 days, respectively. These
values represent upper-bound estimates of the concentrations that might
be found in surface and ground water due to the use of tebufenozide on
pecans. In performing this risk assessment, EPA has calculated drinking
water levels of comparison (DWLOCs) for each of the DEEM population
subgroups. Within each subgroup, the population with the highest
estimated exposure was used to determine the maximum concentration of
tebufenozide that can occur in drinking water without causing an
unacceptable human health risk. As a comparison value, EPA has used the
16.5 ppb value in this risk assessment, as this represents a worst-case
scenario. The DWLOCs for tebufenozide are above the drinking water
estimated concentrations (DWEC) of 16.5 ppb for all population
subgroups. Therefore, the human health risk from exposure to
tebufenozide through drinking water in not likely to exceed EPA's level
of concern.
    Because the Agency lacks sufficient water-related exposure data to
complete a comprehensive drinking water risk assessment for many
pesticides, EPA has commenced and nearly completed a process to
identify a reasonable yet conservative bounding figure for the
potential contribution of water-related exposure to the aggregate risk
posed by a pesticide. In developing the bounding figure, EPA estimated
residue levels in water for a number of specific pesticides using
various data sources. The Agency then applied the estimated residue
levels, in conjunction with appropriate toxicological endpoints cPADs
or acute dietary no observed adverse effect levels (NOAELs) and
assumptions about body weight and consumption, to calculate, for each
pesticide, the increment of aggregate risk contributed by consumption
of contaminated water. While EPA has not yet pinpointed the appropriate
bounding figure for exposure from contaminated water, the ranges the
Agency is continuing to examine are all below the level that would
cause to exceed the cPAD if the tolerances being considered in this
document were granted. The Agency has therefore concluded that the
potential exposures associated with water, even at the higher levels
the Agency is considering as a conservative upper bound, would not
prevent the Agency from determining that there is a reasonable
certainty of no harm if the tolerances are granted.
    3. From non-dietary exposure. Tebufenozide is not currently
registered for use on residential non-food sites. The Agency concludes
that there are no acute, chronic, short- or intermediate-term non-
dietary exposure scenarios.
    4. Cumulative exposure to substances with common mechanism of
toxicity. Section 408(b)(2)(D)(v) 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 does not have, at this time, available data to determine
whether tebufenozide has a common mechanism

[[Page 52460]]

of toxicity with other substances or how to include this pesticide in a
cumulative risk assessment. Unlike other pesticides for which EPA has
followed a cumulative risk approach based on a common mechanism of
toxicity, tebufenozide 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 tebufenozide 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 final rule for Bifenthrin Pesticide Tolerances (62 FR 62961,
November 26, 1997).

 D. Aggregate Risks and Determination of Safety for U.S. Population

    1. Acute risk. Since no acute toxicity endpoints were identified
for tebufenozide, the Agency concludes that acute aggregate risk from
the use of the pesticide will not pose an unacceptable risk to human
health.
    2. Chronic risk. Using the ARC exposure assumptions described in
this unit, EPA has concluded that aggregate exposure from food will
utilize 10% of the cPAD for the U.S. population. The major identifiable
subgroup with the highest aggregate exposure is children (1-6 years
old) at 21% of the cPAD discussed below. Submitted environmental fate
studies suggest that tebufenozide is moderately persistent to
persistent and mobile; thus, tebufenozide could potentially leach to
ground water and runoff to surface water under certain environmental
conditions. The modeling data for tebufenozide indicate levels less
than EPA's DWLOC. EPA generally has no concern for exposures below 100%
of the cPAD because the cPAD represents the level at or below which
daily aggregate dietary exposure over a lifetime will not pose
appreciable risks to human health. Since there is no potential for
exposure to tebufenozide from residential uses, EPA does not expect the
aggregate exposure to exceed 100% of the cPAD. EPA concludes that there
is a reasonable certainty that no harm will result from aggregate
exposure to tebufenozide residues.
    3. Short- and intermediate-term risk. Short- and intermediate-term
aggregate exposure takes into account chronic dietary food and water
(considered to be a background exposure level) plus indoor and outdoor
residential exposure. Due to lack of endpoints and/or residential use
registrations, the agency concludes that short- and intermediate-term
risk via non-dietary routes (e.g., dermal, inhalation, non-dietary
oral) will not pose an unacceptable risk to human health.
    4. Aggregate cancer risk for U.S. population. Tebufenozide has been
classified as a Group E chemical (no evidence of carcinogenicity for
humans). The Agency concludes that the aggregate cancer risk for the
U.S. population is not impacted by the establishment of these
tolerances.
    5. Determination of safety. Based on the risk assessments discussed
above, EPA concludes that there is a reasonable certainty that no harm
will result from aggregate exposure to tebufenozide residues.

E. Aggregate Risks and Determination of Safety for Infants and Children

    1. Safety factor for infants and children-- i. In general. In
assessing the potential for additional sensitivity of infants and
children to residues of tebufenozide, EPA considered data from
developmental toxicity studies in the rat and rabbit and a 2-generation
reproduction study in the rat. The developmental toxicity studies are
designed to evaluate adverse effects on the developing organism
resulting from maternal pesticide exposure gestation. Reproduction
studies provide information relating to effects from exposure to the
pesticide on the reproductive capability of mating animals and data on
systemic toxicity.
    FFDCA section 408 provides that EPA shall apply an additional
tenfold margin of safety for infants and children in the case of
threshold effects to account for pre-and post-natal toxicity and the
completeness of the database 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 margin of exposure (MOE) analysis or through using
uncertainty (safety) factors in calculating a dose level that poses no
appreciable risk to humans. EPA believes that reliable data support
using the standard uncertainty factor (usually 100 for combined inter-
and intra-species variability) and not the additional tenfold MOE/
uncertainty factor when EPA has a complete data base under existing
guidelines and when the severity of the effect in infants or children
or the potency or unusual toxic properties of a compound do not raise
concerns regarding the adequacy of the standard MOE/safety factor.
    ii. Developmental toxicity studies. Developmental toxicity studies
showed no increased sensitivity in fetuses as compared to maternal
animals following in utero exposures in rats and rabbits. See
discussion under Unit II.A of the Final rule for tebufenozide
tolerances published in the Federal Register on April 7, 1999.
    iii. Reproductive toxicity study. Multi-generation reproduction
toxicity studies in rats showed no increased sensitivity in pups as
compared to adults and offsprings. See discussion under Unit II.A of
the Final Rule for tebufenozide tolerances published in the Federal
Register on April 7, 1999.
    iv. Pre- and post-natal sensitivity. The Agency determined that
available data provide no indication of increased sensitivity of rats
or rabbits to in utero and/or postnatal exposure to tebufenozide.
    v. Conclusion. The Agency believes that reliable data support using
the standard 100-fold safety factor for assessing sensitivity to
residues of tebufenozide and that an additional 10-fold margin of
safety for infants and children is not warranted. There is a complete
toxicity database for tebufenozide and exposure data are complete or
estimated based on data that reasonably account for potential
exposures.
    2. Acute risk. No acute toxicity endpoints for tebufenozide have
been identified and this risk assessment is not required. No acute
aggregate risk exist.
    3. Chronic risk. Using the exposure assumptions described in this
unit, EPA has concluded that aggregate exposure to tebufenozide from
food will utilize 21% of the cPAD for children (1-6) the most highly
exposed population subgroup. EPA generally has no concern for exposures
below 100% of the cPAD because the cPAD represents the level at or
below which daily aggregate dietary exposure over a lifetime will not
pose appreciable risks to human health. EPA does not expect the
aggregate exposure from tebufenozide in food, drinking water, and from
non-dietary exposure to exceed the Agency's level of concern.
    4. Short- or intermediate-term risk. Since no short- or
intermediate-term toxicological endpoints were identified by the Agency
for tebufenozide and there are no registered uses that would result in
residential exposure, the Agency concludes that this risk criterion is
negligible and the subject tolerances adequately protect the safety of
infants and children.
    5. Determination of safety. Based on these risk assessments, EPA
concludes that there is a reasonable certainty that no harm will result
to infants and children from aggregate exposure to tebufenozide
residues.

[[Page 52461]]

IV. Other Considerations

A. Metabolism in Plants and Animals

    The qualitative nature of the residue in plants is adequately
understood based upon acceptable apple, sugar beet, and rice metabolism
studies. EPA has concluded that the residue of regulatory concern is
tebufenozide per se. The qualitative nature of the residues in animals
is also adequately understood based on acceptable poultry and ruminant
metabolism studies. For animals, EPA has concluded that the residues of
regulatory concern are tebufenozide and its metabolites benzoic acid,
3,5-dimethyl-1-(1,1-dimethylethyl)-2-((4-carboxymethyl)
benzoyl)hydrazide), benzoic acid, 3-hydroxymethyl,5-methyl-1-(1,1-
dimethylethyl)-2-(4-ethylbenzoyl)hydrazide, the stearic acid conjugate
of benzoic acid, 3-hydroxymethyl,5-methyl-1-(1,1-dimethylethyl)-2-(4-
ethylbenzoyl)hydrazide and benzoic acid, 3-hydroxymethyl-5-methyl-1-
(1,1-dimethylethyl)-2-(4-(1-hydroxyethyl)benzoyl)hydrazide.

B. Analytical Enforcement Methodology

     Turnips. IR-4 used Rohm and Haas High Performance Liquid
Chromatographic (HPLC)/Ultra Violet (UV) analytical method TR-34-94-41
to collect residue data from the field trials on turnips. IR-4 slightly
modified the HPLC system used to quantify tebufenozide residues, but
made no substantive changes. Adequate recovery data and representative
chromatograms for turnip roots and tops were provided. The limit of
quantitation (LOQ) in turnip roots and tops is 0.01 ppm. This method
has been conditionally approved by the Agency as an analytical
enforcement method, pending incorporation of the corrections noted
during the Analytical Chemistry Branch/BEAD's petition method
validation (PMV) trial. This method is considered adequate for the
enforcement of tebufenozide residues in/on turnip roots and tops. A
copy of the corrected version of TR-34-94-41 will be submitted for
publication in the Pesticide Analytical Manual, Volume II (PAM II).
    Canola. IR-4 used Rohm and Haas HPLC/UV analytical method TR-34-96-
135 to collect residue data from the field trials on canola. Adequate
validation data and representative chromatograms for canola commodities
(seed, meal, oil, soapstock) were provided. The LOQ is 0.01 ppm for the
seed and meal and 0.03 ppm for the oil and soapstock. A PMV is not
required, as this method is similar to those for walnuts and apples
which have been successfully validated. A copy of TR-34-96-135
incorporating the corrections specified in the Independent Laboratory
Validation (ILV) study will be submitted for publication in PAM II.
    Adequate enforcement methodology (example - gas chromotography) is
available to enforce the tolerance expression for canola seed and
refined oil and turnip roots and tops. These methods may be requested
from: Calvin Furlow, PRRIB, IRSD (7502C), Office of Pesticide Programs,
Environmental Protection Agency, 401 M St., SW., Washington, DC 20460;
telephone number: (703) 305-5229; e-mail address:
furlow.calvin@epa.gov.

C. Magnitude of Residues

     Turnips. The submitted turnip top and root residue data are
adequate to support the proposed use. The six studies on turnips
adequately address the number and geographic representation of studies
suggested in the OPPTS Test Guidelines. Residues of tebufenozide ranged
from 0.02 to 0.23 ppm for turnip roots and from 0.31 to 8.31 ppm for
turnip tops. The proposed tolerances of 9.0 ppm and 0.3 ppm are
appropriate on turnip tops and turnip roots respectively.
    Canola. The submitted canola residue data are adequate to support
the proposed use. Residues of tebufenozide ranged from 0.29 to 1.64 ppm
for canola seed. The proposed tolerance 2.0 ppm on canola seed is
appropriate. Processed commodities from canola (meal, oil, and
soapstock) were generated using procedures that mimic commercial
practice. Residues of tebufenozide did not concentrate in canola meal
(average concentration factor = 0.16X) or soapstock (1.1X), but did
concentrate in refined oil (an average of 2.3X). Based on the highest
average field trial value for canola seed (1.58 ppm), a tolerance of
4.0 ppm is appropriate for refined canola oil.

D. International Residue Limits

     No CODEX, Canadian or Mexican limits for tebufenozide were
established on the subject crops at the time of this review.

V. Conclusion

    Therefore, the tolerance is established for residues of
tebufenozide; benzoic acid, 3,5-dimethyl-, 1-(1,1-dimethylethyl)-2-(4-
ethylbenzoyl) hydrazide in turnip tops, turnip roots, canola seed, and
refined canola oil at 9.0, 0.3, 2.0, and 4.0 ppm, respectively.

VI. Objections and Hearing Requests

    Under section 408(g) of the FFDCA, as amended by the FQPA, any
person may file an objection to any aspect of this regulation and may
also request a hearing on those objections. The EPA procedural
regulations which govern the submission of objections and requests for
hearings appear in 40 CFR part 178. Although the procedures in those
regulations require some modification to reflect the amendments made to
the FFDCA by the FQPA of 1996, EPA will continue to use those
procedures, with appropriate adjustments, until the necessary
modifications can be made. The new section 408(g) provides essentially
the same process for persons to "object" to a regulation for an
exemption from the requirement of a tolerance issued by EPA under new
section 408(d), as was provided in the old FFDCA sections 408 and 409.
However, the period for filing objections is now 60 days, rather than
30 days.

A. What Do I Need to Do to File an Objection or Request a Hearing?

    You must file your objection or request a hearing on this
regulation in accordance with the instructions provided in this unit
and in 40 CFR part 178. To ensure proper receipt by EPA, you must
identify docket control number OPP-300923 in the subject line on the
first page of your submission. All requests must be in writing, and
must be mailed or delivered to the Hearing Clerk on or before November
29, 1999.
    1. Filing the request. Your objection must specify the specific
provisions in the regulation that you object to, and the grounds for
the objections (40 CFR 178.25). If a hearing is requested, the
objections must include a statement of the factual issues(s) on which a
hearing is requested, the requestor's contentions on such issues, and a
summary of any evidence relied upon by the objector (40 CFR 178.27).
Information submitted in connection with an objection or hearing
request may be claimed confidential by marking any part or all of that
information as CBI. Information so marked will not be disclosed except
in accordance with procedures set forth in 40 CFR part 2. A copy of the
information that does not contain CBI must be submitted for inclusion
in the public record. Information not marked confidential may be
disclosed publicly by EPA without prior notice.
    Mail your written request to: Office of the Hearing Clerk (1900),
Environmental Protection Agency, 401 M St., SW., Washington, DC 20460.
You may also deliver your request to the Office of the Hearing Clerk in
Room M3708,

[[Page 52462]]

Waterside Mall, 401 M St., SW., Washington, DC 20460. The Office of the
Hearing Clerk is open from 8 a.m. to 4 p.m., Monday through Friday,
excluding legal holidays. The telephone number for the Office of the
Hearing Clerk is (202) 260-4865.
    2. Tolerance fee payment. If you file an objection or request a
hearing, you must also pay the fee prescribed by 40 CFR 180.33(i) or
request a waiver of that fee pursuant to 40 CFR 180.33(m). You must
mail the fee to: EPA Headquarters Accounting Operations Branch, Office
of Pesticide Programs, P.O. Box 360277M, Pittsburgh, PA 15251. Please
identify the fee submission be labeling it "Tolerance Petition Fees."
    EPA is authorized to waive any fee requirement "when in the
judgement of the Administrator such a waiver or refund is equitable and
not contrary to the purpose of this subsection." For additional
information regarding the waiver of these fees, you may contact James
Tompkins by phone at (703) 305-5697, by e-mail at tompkins.jim@epa.gov,
or by mailing a request for information to Mr. Tompkins at Registration
Division (7505C), Office of Pesticide Programs, Environmental
Protection Agency, 401 M St., SW., Washington, DC 20460.
    If you would like to request a waiver of the tolerance objection
fees, you must mail your request for such a waiver to: James Hollins,
Information Resources and Services Division (7502C), Office of
Pesticide Programs, Environmental Protection Agency, 401 M St., SW.,
Washington, DC 20460.
    3. Copies for the Docket. In addition to filing an objection or
hearing request with the Hearing Clerk as described in Unit VI.A. of
this preamble, you should also send a copy of your request to the PIRB
for its inclusion in the official record that is described in Unit
I.B.2. of this preamble. Mail your copies, identified by docket number
OPP-300923, to: Public Information and Records Integrity Branch,
Information Resources and Services Division (7502C), Office of
Pesticide Programs, Environmental Protection Agency, 401 M St., SW.,
Washington, DC 20460. In person or by courier, bring a copy to the
location of the PRIB described in Unit I.B.2. of this preamble. You may
also send an electronic copy of your request via e-mail to: opp-
docket@epa.gov. Please use an ASCII file format and avoid the use of
special characters and any form of encryption. Copies of electronic
objections and hearing requests will also be accepted on disks in
WordPerfect 5.1/6.1 file format or ASCII file format. Do not include
any CBI in your electronic copy. You may also submit an electronic copy
of your request at many Federal Depository Libraries.

B. When Will the Agency Grant a Request for a Hearing?

    A request for a hearing will be granted if the Administrator
determines that the material submitted shows the following: There is a
genuine and substantial issue of fact; there is a reasonable
possibility that available evidence identified by the requestor would,
if established resolve one or more of such issues in favor of the
requestor, taking into account uncontested claims or facts to the
contrary; and resolution of the factual issues(s) in the manner sought
by the requestor would be adequate to justify the action requested (40
CFR 178.32).

VII. Regulatory Assessment Requirements

    This final rule establishes tolerances under section 408(d) of the
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). 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., or 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). Nor
does it require prior consultation with State, local, and tribal
government officials as specified by Executive Order 12875, entitled
Enhancing the Intergovernmental Partnership (58 FR 58093, October 28,
1993) and Executive Order 13084, entitled Consultation and Coordination
with Indian Tribal Governments (63 FR 27655, May 19,1998), or special
consideration of environmental justice related issues under Executive
Order 12898, entitled Federal Actions to Address Environmental Justice
in Minority Populations and Low-Income Populations (59 FR 7629,
February 16, 1994), or require OMB review in accordance with Executive
Order 13045, entitled Protection of Children from Environmental Health
Risks and Safety Risks (62 FR 19885, April 23, 1997). The Agency has
determined that this action will not have a substantial direct effect
on States, on the relationship between the national government and the
States, or on the distribution of power and responsibilities among the
various levels of government, as specified in Executive Order 12612,
entitled Federalism (52 FR 41685, October 30, 1987). This action
directly regulates growers, food processors, food handlers and food
retailers, not States. This action does not alter the relationships or
distribution of power and responsibilities established by Congress in
the preemption provisions of the Federal Food, Drug, and Cosmetic Act,
21 U.S.C. 346a(b)(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 of 1995 (NTTAA), Public Law
104-113, section 12(d) (15 U.S.C. 272 note). In addition, since
tolerances and exemptions that are established on the basis of a
petition under FFDCA section 408(d), 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.

VIII. Submission to Congress and the Comptroller General

     The Congressional Review Act, 5 U.S.C. 801 et seq., as added by
the Small Business Regulatory Enforcement Fairness Act of 1996,
generally provides that before a rule may take effect, the agency
promulgating the rule must submit a rule report, which includes a copy
of the rule, 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 rule in the  Federal Register. This rule
is not a "major rule" as defined by 5 U.S.C. 804(2).
