II. Summary of Petitioned-for Tolerance

    In the Federal Register of May 19, 2010 (75 FR 28009) (FRL-8823-2), 
EPA issued a notice pursuant to section 408(d)(3) of FFDCA, 21 U.S.C. 
346a(d)(3), announcing the filing of a pesticide petition (PP 9E7675) 
by IR-4, Rutgers, The State University of New Jersey, 500 College Road 
East, Suite 201 W., Princeton, NJ 08540. The petition requested that 40 
CFR part 180 be amended by establishing tolerances for residues of the 
miticide/ovicide etoxazole, 2-(2,6-difluorophenyl)-4-[4-(1,1-
dimethylethyl)-2-ethoxyphenyl]-4,5-dihydrooxazole, in or on peppers, 
African eggplant, eggplant, martynia, okra, pea eggplant, pepino, 
roselle, and scarlet eggplant at 0.20 ppm; Crop Group 9: Cucurbit 
vegetables at 0.20 ppm; Subgroup 13-07A: Caneberry at 1.1 ppm; Subgroup 
13-07F: Small fruit vine climbing subgroup except fuzzy kiwi at 0.50 
ppm; Subgroup 13-07G: Low-growing berry subgroup at 0.50 ppm and 
avocado, papaya, star apple, black sapote, mango, sapodilla, canistel, 
and mamey sapote at 0.20 ppm; and tea at 15 ppm. The petition also 
proposed to delete the established tolerances in or on strawberry, 
grape, cucumber, and vegetable, cucurbit subgroup 9A since

[[Page 20538]]

they would be covered by the proposed new tolerances. That notice 
referenced a summary of the petition prepared by Valent, the 
registrant, which is available in the docket, http://www.regulations.gov. A comment was received on the notice of filing. 
EPA's response to this comment is discussed in Unit IV.C.
    Based upon review of the data supporting the petition, EPA has 
modified the levels at which some of the tolerances are being set and 
is setting a subgroup tolerance instead of separate tolerances for some 
commodities. It was also determined that the proposed deletion of the 
cucurbit subgroup 9A and establishment of a tolerance for the cucurbit 
vegetables crop group 9 could not be done due to differences in 
tolerance levels between subgroups 9A and 9B. Finally, the tolerance 
expression is being revised to be consistent with current Agency 
policy. The reasons for these changes are explained in Unit IV.D.

III. 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 section 408(b)(2)(D) of FFDCA, and the factors 
specified in section 408(b)(2)(D) of 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 and to 
make a determination on aggregate exposure for etoxazole including 
exposure resulting from the tolerances established by this action. 
EPA's assessment of exposures and risks associated with etoxazole 
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 existing etoxazole data indicate that it possesses low acute 
toxicity via all routes of exposure. It is not an eye or dermal 
irritant or a dermal sensitizer. No toxicity was seen at the limit dose 
in a 28-day dermal toxicity study in rats.
    The liver is the main target organ in mice, rats and dogs. In a 90-
day toxicity study in dogs, increased liver weights and centrilobular 
hepatocellular swelling in the liver were observed. Similar effects 
were observed in a chronic toxicity study in dogs at similar doses, 
indicating that systemic effects (mainly liver effects) occur at 
similar dose levels following short- through long-term exposure without 
increasing in severity. In a 90-day toxicity study in mice, 
hepatotoxicity (increased relative liver weight, liver enlargement, and 
centrilobular hepatocellular swelling) was observed at high doses. 
Similar effects were observed at the high dose in a mouse 
carcinogenicity study. Subchronic and chronic toxicity studies in rats 
produced similar effects (increased liver weights, centrilobular 
hepatocellular swelling, etc.) to those seen in mice and dogs. In 
addition, slight increases in thyroid weights and incisors were 
observed in subchronic and chronic toxicity studies in rats at high 
doses and at terminal stages of the study. Toxicity was not observed at 
the highest dose tested (HDT) in another carcinogenicity study in mice. 
There is no evidence of immunotoxicity or neurotoxicity in any of the 
submitted studies.
    Two studies in mice showed no evidence of carcinogenicity up to the 
HDT. In a rat carcinogenicity study, which was deemed unacceptable due 
to inadequate dosing, benign interstitial cell tumors (testis) and 
pancreas benign islet cell adenomas were observed (in females) at the 
high dose. These effects were not observed in an acceptable 
carcinogenicity study in rats at higher doses. In special mechanistic 
male rat studies there were no observable changes in serum hormone 
levels (estradiol, luteinizing hormone (LH), prolactin and 
testosterone) or reproductive effects (interstitial cell proliferation 
or spermatogenesis) noted. EPA classified etoxazole as ``not likely to 
be carcinogenic to humans.'' Etoxazole is not mutagenic.
    The toxicology data for etoxazole provides no indication of 
increased susceptibility, as compared to adults, of rat and rabbit 
fetuses to in utero exposure in developmental studies. The rabbit 
developmental toxicity study included maternal toxic effects (liver 
enlargement, decreased weight gain, and decreased food consumption) at 
the same dose as developmental effects (increased incidences of 27 
presacral vertebrae and 27 presacral vertebrae with 13th ribs). In the 
2-generation reproduction study conducted with rats, offspring toxicity 
was more severe (pup mortality) than parental toxicity (increased liver 
and adrenal weights) at the same dose, indicating increased qualitative 
susceptibility.
    Specific information on the studies received and the nature of the 
adverse effects caused by etoxazole as well as the no-observed-adverse-
effect-level (NOAEL) and the lowest-observed-adverse-effect-level 
(LOAEL) from the toxicity studies can be found at http://www.regulations.gov in docket ID number EPA-HQ-OPP-2010-0063 in the 
document titled Etoxazole; ``Human Health Risk Assessment for Proposed 
Tolerances and Uses on Peppers (Bell and Non-bell); Squash/Cucumbers 
(Subgroup 9B); Avocado; Tropical and Subtropical Fruits (Inedible 
Peel); Caneberry Subgroup 13-07A; Small Fruit Vine Climbing, Except 
Kiwifruit, Subgroup 13-07F; Low-growing Berry, Subgroup 13-07G; and 
Tea,'' pp. 29-31.

B. 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

[[Page 20539]]

estimates 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.

human risk assessment is shown in the following Table:

C. Exposure Assessment

    1. Dietary exposure from food and feed uses. In evaluating dietary 
exposure to etoxazole, EPA considered exposure under the petitioned-for 
tolerances as well as all existing etoxazole tolerances in 40 CFR 
180.593. EPA assessed dietary exposures from etoxazole in food as 
follows:
    i. Acute exposure. Quantitative acute dietary exposure and 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.
    No such effects were identified in the toxicological studies for 
etoxazole; therefore, a quantitative acute dietary exposure assessment 
is unnecessary.
    ii. Chronic exposure. In conducting the chronic dietary exposure 
assessment EPA used the food consumption data from the USDA 1994-1996 
and 1998 Continuing Surveys for Food Intake by Individuals (CSFII). As 
to residue levels in food, an unrefined, chronic dietary exposure 
assessment was performed for the general U.S. population and various 
population subgroups using tolerance-level residues for all 
agricultural commodities and 100 percent crop treated (PCT).
    iii. Cancer. EPA determines whether quantitative cancer exposure 
and risk assessments are appropriate for a food-use pesticide based on 
the weight of the evidence from cancer studies and other relevant data. 
If quantitative cancer risk assessment is appropriate, Cancer risk may 
be quantified using a linear or nonlinear approach. If sufficient 
information on the carcinogenic mode of action is available, a 
threshold or non-linear approach is used and a cancer RfD is calculated 
based on an earlier noncancer key event. If carcinogenic mode of action 
data are not available, or if the mode of action data determines a 
mutagenic mode of action, a default linear cancer slope factor approach 
is utilized. Based on the data summarized in Unit III.A., EPA has 
concluded that etoxazole does not pose a cancer risk to humans. 
Therefore, a dietary exposure assessment for the purpose of assessing 
cancer risk is unnecessary.
    2. Dietary exposure from drinking water. The Agency used screening 
level water exposure models in the dietary exposure analysis and risk 
assessment for etoxazole in drinking water. These simulation models 
take into account data on the physical, chemical, and fate/transport 
characteristics of etoxazole. 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 First Index Reservoir Screening Tool (FIRST), and 
Screening Concentration in Ground Water (SCI-GROW) models, the 
estimated drinking water concentrations (EDWCs) of etoxazole for 
chronic exposures for non-cancer assessments are estimated to be 4.761 
parts per billion (ppb) for surface water and 0.318 ppb for ground 
water.
    Modeled estimates of drinking water concentrations were directly 
entered into the dietary exposure model. For chronic dietary risk 
assessment, the water concentration of value 4.761 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, and flea and tick control on pets). Etoxazole is not 
registered for any specific use patterns that would result in 
residential exposure.
    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 etoxazole to share a common mechanism of toxicity 
with any other substances, and etoxazole does not appear to produce a 
toxic metabolite produced by other substances. For the purposes of this 
tolerance action, therefore, EPA has assumed that etoxazole does not 
have a

[[Page 20540]]

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 http://www.epa.gov/pesticides/cumulative.

D. 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 Food Quality 
Protection Act (FQPA) Safety Factor (SF). In applying this provision, 
EPA either retains the default value of 10x, or uses a different 
additional safety factor when reliable data available to EPA support 
the choice of a different factor.
    2. Prenatal and postnatal sensitivity. The toxicology data for 
etoxazole provides no indication of increased susceptibility, as 
compared to adults, of rat and rabbit fetuses to in utero exposure in 
developmental studies. In a rat reproduction study, offspring toxicity 
was more severe (pup mortality) than parental toxicity (increased liver 
and adrenal weights) at the same dose; thereby indicating increased 
qualitative susceptibility. Based on the concerns in this unit, a 
Degree of Concern Analysis was performed by EPA, which concluded that 
concern is low since:
    i. The effects in pups are well-characterized with a clear NOAEL;
    ii. The pup effects occur at the same dose as parental toxicity; 
and
    iii. The doses selected for various risk assessment scenarios are 
lower (~3000-fold lower) than the doses that caused offspring toxicity 
in the rat 2-generation reproduction study. Therefore, the endpoints 
selected for risk assessment are protective of the effects seen in the 
rat reproduction study.
    3. Conclusion. EPA has determined that reliable data show 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 etoxazole is complete except for acute 
and subchronic neurotoxicity and immunotoxicity studies. Changes to 40 
CFR 180.158 make acute and subchronic neurotoxicity testing (OPPTS 
Guideline 870.6200), and immunotoxicity testing (OPPTS Guideline 
870.7800) required for pesticide registration. Although these studies 
are not yet available for etoxazole, the available data do not show any 
evidence of treatment-related effects on the immune system. Further, 
there is no evidence of neurotoxicity in any study in the toxicity 
database for etoxazole. Therefore, EPA does not believe that conducting 
neurotoxicity and immunotoxicity studies will result in a NOAEL lower 
than the NOAEL of 4.62 mg/kg/day already established for etoxazole. 
Consequently, an additional database uncertainty factor does not need 
to be applied.
    ii. There is no indication that etoxazole is a neurotoxic chemical 
and there is no need for a developmental neurotoxicity study or 
additional UFs to account for neurotoxicity.
    iii. Although there is qualitative evidence of increased 
susceptibility of offspring (pup mortality) compared to less severe 
parental effects (increased liver and adrenal weights) at the same dose 
in the rat multi-generation reproduction study, the Agency did not 
identify any residual uncertainties after establishing toxicity 
endpoints and traditional UFs (10x for interspecies variation and 10x 
for intraspecies variation) to be used in the risk assessment. 
Therefore, there are no residual concerns regarding developmental 
effects in the young.
    iv. There are no residual uncertainties identified in the exposure 
databases. The dietary food exposure assessments were performed based 
on 100 PCT and tolerance-level residues. EPA made conservative 
(protective) assumptions in the ground and surface water modeling used 
to assess exposure to etoxazole in drinking water. These assessments 
will not underestimate the exposure and risks posed by etoxazole.

E. 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. No adverse effect resulting from a single oral exposure 
was identified and no acute dietary endpoint was selected. Therefore, 
etoxazole 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 
etoxazole from food and water will utilize 11% of the cPAD for children 
1-2 years old, the population group receiving the greatest exposure. 
There are no residential uses for etoxazole.
    3. Short and intermediate-term risk. Short- and intermediate-term 
aggregate exposure takes into account short- and intermediate-term 
residential exposure plus chronic exposure to food and water 
(considered to be a background exposure level).
    A short- and/or intermediate-term adverse effect was identified; 
however, etoxazole is not registered for any use patterns that would 
result in short- and/or intermediate-term residential exposure. Short- 
and/or intermediate-term risk is assessed based on short- and/or 
intermediate term residential exposure plus chronic dietary exposure. 
Because there is no short- and/or intermediate-term residential 
exposure and chronic dietary exposure has already been assessed under 
the appropriately protective cPAD (which is at least as protective as 
the POD used to assess short- and/or intermediate-term risk), no 
further assessment of short- and/or intermediate-term risk is 
necessary, and EPA relies on the chronic dietary risk assessment for 
evaluating short- and/or intermediate-term risk for etoxazole.
    4. Aggregate cancer risk for U.S. population. Based on the lack of 
evidence of carcinogenicity in two adequate rodent carcinogenicity 
studies, etoxazole is not expected to pose a cancer risk to humans.
    5. 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 etoxazole residues.

IV. Other Considerations

A. Analytical Enforcement Methodology

    Adequate enforcement methodologies (gas chromatography/nitrogen-
phosphorus detection (GC/NPD) and gas chromatography/mass selective 
detection (GC/MSD) methods) are available to enforce the tolerance 
expression. The method may be requested from: Chief, Analytical

[[Page 20541]]

Chemistry Branch, Environmental Science Center, 701 Mapes Rd., Ft. 
Meade, MD 20755-5350; telephone number: (410) 305-2905; e-mail 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). The Codex Alimentarius is a joint U.N. 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 MRLs for etoxazole for the 
commodities discussed in this document.

C. Response to Comments

    EPA received a comment from a private citizen expressing concerns 
for genetically modified vegetables and undue risks from pesticides. 
However, this action does not involve use of genetically modified 
vegetables. Additionally, when new or amended tolerances are requested 
for the presence of the residues of a pesticide and its toxicologically 
significant metabolite(s) in food or feed, the Agency, as is required 
by section 408 of the Federal Food, Drug and Cosmetic Act (FFDCA), 
estimates the risk of the potential exposure to these residues by 
performing an aggregate risk assessment. Such a risk assessment 
integrates the individual assessments that are conducted for food, 
drinking water, and residential exposures. Additionally, the Agency, as 
is further required by section 408 of the FFDCA, considers available 
information concerning what are termed the cumulative toxicological 
effects of the residues of that pesticide and of other substances 
having a common mechanism of toxicity with it. The Agency has concluded 
after this assessment that there is a reasonable certainty that no harm 
will result from exposure to the residues of interest. Therefore, the 
proposed tolerances are found to be acceptable. These assessments 
consider body residue loads of the pesticide, as well as available 
information concerning the potential that other substances have a 
common mechanism of toxicity, in reaching a conclusion as to whether or 
not the reasonable certainty of no harm decision can be made.

D. Revisions to Petitioned-for Tolerances

    Upon review of the data supporting the petition, EPA revised the 
tolerance for caneberry subgroup 13-07A from 1.1 ppm to 1.5 ppm based 
on analysis of the residue field trial data using the Agency's 
Tolerance Spreadsheet in accordance with the Agency's Guidance for 
Setting Pesticide Tolerances Based on Field Trial Data.
    The Agency also corrected the commodity definition from ``fruit, 
small, vine climbing, subgroup 13-07F, except fuzzy kiwifruit'' to 
``fruit, small vine climbing, except fuzzy kiwifruit, subgroup 13-
07F.''
    EPA has also determined that the petitioned-for tolerance on tea at 
15 ppm should be established as a tolerance with no U.S. registrations 
on tea, dried at 15 ppm. At least one U.S. residue field trial study is 
required to establish a domestic registration on tea; however, no U.S. 
residue field trial data were submitted in support of the use of 
etoxazole on tea. Therefore, the Agency has established a tolerance 
with no U.S. registrations on tea, dried at 15 ppm.
    Additionally, IR-4 petitioned for individual tolerances on peppers, 
African eggplant, eggplant, martynia, okra, pea eggplant, pepino, 
roselle, and scarlet eggplant (PP 9E7675). In the Federal Register of 
December 8, 2010 (75 FR 76284-76292) (FRL-8853-8), EPA issued a final 
rule that revised the crop grouping regulations. As part of this 
action, EPA retained the pre-existing Crop Group 8 and added a new 
group titled ``Crop Group 8-10 Fruiting Vegetable Group.'' The new crop 
group 8-10 added new commodities and created new subgroups (including a 
subgroup consisting of the commodities requested in PP 9E7675). EPA 
indicated in the December 8, 2010 final rule as well as the earlier 
January 6, 2010 proposed rule (75 FR 807) (FRL-8801-2) that, for 
existing petitions for which a Notice of Filing had been published, the 
Agency would attempt to conform these petitions to the rule. Therefore, 
consistent with this rule, EPA is establishing a tolerance on the 
pepper/eggplant subgroup 8-10B. EPA concludes it is reasonable to 
establish the tolerance on the newly created subgroup, since the 
individual commodities for which tolerances were requested are 
identical to those which comprise the pepper/eggplant subgroup 8-10B.
    Also, because of differences in the tolerance levels between 
subgroup 9A (melon subgroup) and 9B (squash/cucumber subgroup), the two 
cannot be combined into a single tolerance under Crop Group 9 Cucurbit 
Vegetables as proposed in the petition. Accordingly, other than the 
nomenclature change to the existing subgroup 9A tolerance noted below, 
EPA is leaving the existing subgroup 9A tolerance intact and adding a 
new tolerance for subgroup 9B. In order to use the correct 
nomenclature, the existing tolerance for ``vegetable, cucurbit subgroup 
9A'' is being re-named ``melon subgroup 9A.''
    Finally, EPA has revised the tolerance expression to clarify:
    1. That, as provided in FFDCA section 408(a)(3), the tolerance 
covers metabolites and degradates of etoxazole not specifically 
mentioned; and
    2. That compliance with the specified tolerance levels is to be 
determined by measuring only the specific compounds mentioned in the 
tolerance expression.

V. Conclusion

    Therefore, tolerances are established for residues of etoxazole, 2-
(2,6-difluorophenyl)-4-[4-(1,1-dimethylethyl)-2-ethoxyphenyl]-4,5-
dihydrooxazole, in or on pepper/eggplant subgroup 8-10B at 0.20 ppm; 
tea, dried at15 ppm; berry, low growing, subgroup 13-07G at 0.50 ppm; 
fruit, small vine climbing, except fuzzy kiwifruit, subgroup 13-07F at 
0.50 ppm; squash/cucumber subgroup 9B at 0.02 ppm; avocado at 0.20 ppm; 
papaya at 0.20 ppm; star apple at 0.20 ppm; sapote, black at 0.20 ppm; 
mango at 0.20 ppm; sapodilla at 0.20 ppm; canistel at 0.20 ppm; sapote, 
mamey at 0.20 ppm; and caneberry subgroup 13-07A at 1.5 ppm.

VI. Statutory and Executive Order Reviews

    This final rule establishes tolerances 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 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

[[Page 20542]]

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 (65 FR 
67249, November 9, 2000) do not apply to this final rule. In addition, 
this final 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) (Pub. L. 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 of 1995 (NTTAA), Public Law 104-113, section 12(d) (15 U.S.C. 272 
note).

VII. Congressional Review Act

    The Congressional Review Act, 5 U.S.C. 801 et seq., generally 
provides that before a rule may take effect, the agency promulgating 
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).
