II. Summary of Petitioned-For Tolerance

    In the Federal Register of May 19, 2016 (81 FR 31581) (FRL-9946-
02), EPA issued a document pursuant to FFDCA section 408(d)(3), 21 
U.S.C. 346a(d)(3), announcing the filing of a pesticide petition (PP 
5E8434) by IR-4, Rutgers University, 500 College Rd. East, Suite 201 W, 
Princeton, NJ 08540. The petition requested that 40 CFR 180.579 be 
amended by establishing tolerances for residues of fenamidone (4H-
imidazol-4-one, 3,5-dihydro-5-methyl-2-(methylthio)-5-phenyl-3-
(phenylamino)-, (S)-) in or on the following raw agricultural 
commodities: Basil, fresh leaves at 30 parts per million (ppm); and 
basil, dried leaves at 200 ppm. Additionally, tolerances were proposed 
for the crops in the proposed crop subgroup 4-15A, leafy greens 
subgroup at 60.0 ppm, including amaranth, Chinese; amaranth, leafy; 
aster, Indian; blackjack; cat's whiskers; chervil, fresh leaves; cham-
chwi; cham-na-mul; chipilin; chrysanthemum, garland; cilantro, fresh 
leaves; corn salad; cosmos; dandelion; dang-gwi; dillweed; dock; dol-
nam-mul; ebolo; endive; escarole; fameflower; feather cockscomb; good 
king henry; huauzontle; jute, leaves; lettuce, bitter; lettuce, head; 
lettuce, leaf; orach; parsley, fresh leaves; plantain, buckhorn; 
primrose, English; purslane, garden; purslane, winter; radicchio; 
spinach; spinach, malabar; spinach, New Zealand; spinach, tanier; swiss 
chard; and violet, Chinese; the crops in the proposed crop subgroup 4-
15B, Brassica leafy greens subgroup at 55 ppm, including arugula; 
broccoli raab; broccoli, Chinese; cabbage, Abyssinian; cabbage, 
seakale; Chinese cabbage, bok choy; collards; cress, garden; cress, 
upland; hanover salad; kale; maca; mizuna; mustard greens; radish, 
leaves; rape greens; rocket, wild; shepherd's purse; turnip greens; and 
watercress; the crops in the proposed crop subgroup 22B, leaf petiole 
vegetable subgroup at 60 ppm, including cardoon; celery; celery, 
Chinese; fuki; rhubarb; udo; and zuiki; the crops in the proposed crop 
group 5-15 (Brassica head and stem vegetable) at 5.0 ppm, including 
broccoli; brussels sprouts; cabbage; cabbage, Chinese, napa; and 
cauliflower; cottonseed subgroup 20C at 0.02 ppm; kohlrabi at 5.0 ppm; 
celtuce at 60 ppm; and fennel, Florence, fresh leaves and stalk at 60 
ppm. That petition also requested that the following existing 
tolerances be removed after the petitioned-for tolerances are issued 
since they would be superseded by the new tolerances: Brassica, head 
and stem, subgroup 5A at 5.0 ppm; Brassica, leafy greens, subgroup 5B 
at 55 ppm; cotton, undelinted seed at 0.02 ppm; cilantro, leaves at 60 
ppm; and vegetable, leafy, except Brassica, group 4 at 60 ppm. That 
document referenced a summary of the petition prepared by Bayer 
CropScience, the registrant, which is available in the docket, http://www.regulations.gov. No comments were received on the notice of filing.
    EPA is establishing tolerances similar to those requested by the 
petitioner (the leafy greens crop subgroup 4-15A; the Brassica leafy 
greens crop subgroup 4-15B; the leaf petiole vegetable crop subgroup 
22B; and the Brassica head and stem vegetable crop group 5-15), except 
that due to the recent establishment of the new crop groups, the Agency 
is referencing the current crop groups. Additionally, in order to 
harmonize with Canada, the Agency is establishing a single tolerance 
for leafy vegetable crop group 4-16 rather than two separate tolerances 
for each of the crop subgroup 4-16A and 4-16B.

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 FFDCA section 408(b)(2)(D), and the factors 
specified in FFDCA section 408(b)(2)(D), EPA has reviewed the available 
scientific data and other relevant information in support of this 
action. EPA has sufficient data to assess the hazards of and to make a 
determination on aggregate exposure for fenamidone including exposure 
resulting from the tolerances established by this action. EPA's 
assessment of exposures and risks associated with fenamidone 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.

[[Page 35111]]

    The target organs in fenamidone are the liver in mice, rats and 
dogs, and the thyroid in rats. Liver effects include liver weight 
increases, liver enlargement, and histopathological observation. 
Enlarged thyroid, increased thyroid weights with an increase incidence 
of a slight, diffuse follicular hypertrophy and/or hyperplasia were 
observed in rats of both sexes in the chronic toxicity study.
    In the acute neurotoxicity study in rats, clinical signs included 
staining of the anogenital region, mucous in the feces, hunched 
posture, and unsteady gait. In the subchronic neurotoxicity study in 
rats, marginal decreases in brain weights were observed only in high 
dose males. Additionally, decreased brain weight occurred in the rat 
reproduction study. In a developmental neurotoxicity study in Wistar 
rats, no neurobehavioral effects and no neuropathological changes were 
observed at any dose in the offspring, but decreased body weight was 
observed during pre- and post-weaning.
    Fenamidone did not demonstrate qualitative or quantitative 
increased susceptibility in the rat or rabbit developmental toxicity 
studies or the 2-generation rat reproduction study. There were no 
developmental effects up to the highest dose tested and in the presence 
of maternal toxicity in rats and rabbits. In the reproduction study in 
rats, decreased absolute brain weight in F2 female pups occurred at the 
same dose levels as decreased absolute brain weight in F1 parental 
females; there were no effects on fertility or other measured 
reproductive parameters. Immunosuppression was demonstrated at the 
highest dose tested in the immunotoxicity study; however, the existing 
risk assessment points of departure are lower and are protective of 
this potential effect.
    Fenamidone is classified as ``not likely to be a human carcinogen'' 
by all relevant routes of exposure. All mutagenicity studies were 
negative for both the parent and plant metabolites (RPA 412636, RPA 
412708, and RPA 410193), except the parent induced mutant colonies at 
the tk locus and increased chromosomal aberrations in human peripheral 
blood.
    Specific information on the studies received and the nature of the 
adverse effects caused by fenamidone 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 the document titled ``Fenamidone: Human 
Health Risk Assessment to Support the Section (3) Registration on Basil 
and Crop Group Expansion on Brassica Head and Stem Vegetables; Leafy 
greens; Brassica Leafy Greens; and Cottonseed'' on page 33 in docket ID 
number EPA-HQ-OPP-2016-0064.

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 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://www2.epa.gov/pesticide-science-and-assessing-pesticide-risks/assessing-human-health-risk-pesticides.
    A summary of the toxicological endpoints for fenamidone used for 
human risk assessment is shown in Table 1 of this unit.

C. Exposure Assessment

    1. Dietary exposure from food and feed uses. In evaluating dietary 
exposure to fenamidone, EPA considered exposure under the petitioned-
for tolerances as well as all existing fenamidone tolerances in 40 CFR 
180.579. EPA assessed dietary

[[Page 35112]]

exposures from fenamidone 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.
    Such effects were identified for fenamidone. In estimating acute 
dietary exposure, EPA used 2003-2008 food consumption information from 
the U.S. Department of Agriculture's (USDA's) National Health and 
Nutrition Examination Survey, ``What We Eat in America'' (NHANES/
WWEIA). As to residue levels in food, EPA used field-trial residue 
values, assumed 100 percent crop treated (PCT) for all commodities, and 
incorporated Dietary Exposure Evaluation Model (DEEM)TM 
default processing factors and empirical factors for processed 
commodities.
    ii. Chronic exposure. In conducting the chronic dietary exposure 
assessment EPA used the 2003-2008 food consumption data from the USDA's 
NHANES/WWEIA. As to residue levels in food, EPA used field-trial 
residue values, assumed 100 PCT for all commodities, and incorporated 
Dietary Exposure Evaluation Model (DEEM)TM default 
processing factors and empirical factors for processed commodities.
    iii. Cancer. Based on the data summarized in Unit III.A., EPA has 
concluded that fenamidone does not pose a cancer risk to humans. 
Therefore, a dietary exposure assessment for the purpose of assessing 
cancer risk is unnecessary.
    iv. Anticipated residue/Percent Crop Treated information. Although 
the Agency assumed 100 percent crop treated for all commodities, EPA 
used anticipated residue information in the assessment for this 
fenamidone tolerance action. Section 408(b)(2)(E) of FFDCA authorizes 
EPA to use available data and information on the anticipated residue 
levels of pesticide residues in food and the actual levels of pesticide 
residues that have been measured in food. If EPA relies on such 
information, EPA must require pursuant to FFDCA section 408(f)(1) that 
data be provided 5 years after the tolerance is established, modified, 
or left in effect, demonstrating that the levels in food are not above 
the levels anticipated. For the present action, EPA will issue such 
data call-ins as are required by FFDCA section 408(b)(2)(E) and 
authorized under FFDCA section 408(f)(1). Data will be required to be 
submitted no later than 5 years from the date of issuance of these 
tolerances.
    2. Dietary exposure from drinking water. The Agency used screening 
level water exposure models in the dietary exposure analysis and risk 
assessment for fenamidone in drinking water. These simulation models 
take into account data on the physical, chemical, and fate/transport 
characteristics of fenamidone. Further information regarding EPA 
drinking water models used in pesticide exposure assessment can be 
found at http://www2.epa.gov/pesticide-science-and-assessing-pesticide-risks/about-water-exposure-models-used-pesticide.
    Based on the Tier II Pesticide Root Zone Model/Exposure Analysis 
Modeling System (PRZM/EXAMS)--Index Reservoir model and Pesticide Root 
Zone Model Ground Water (PRZM GW), the estimated drinking water 
concentrations (EDWCs) of fenamidone for acute exposures are estimated 
to be 41.7 parts per billion (ppb) for surface water and 207 ppb for 
ground water, and for chronic exposures are estimated to be 11.9 ppb 
for surface water and 207 ppb for ground water.
    Modeled estimates of drinking water concentrations were directly 
entered into the dietary exposure model. For both the acute and chronic 
dietary risk assessments, the ground water concentration value of 207 
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).
    Fenamidone 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 fenamidone to share a common mechanism of 
toxicity with any other substances, and fenamidone does not appear to 
produce a toxic metabolite produced by other substances. For the 
purposes of this tolerance action, therefore, EPA has assumed that 
fenamidone does not have a common mechanism of toxicity with other 
substances. For information regarding EPA's efforts to determine which 
chemicals have a common mechanism of toxicity and to evaluate the 
cumulative effects of such chemicals, see EPA's Web site at http://www2.epa.gov/pesticide-science-and-assessing-pesticide-risks/cumulative-assessment-risk-pesticides.

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 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. Fenamidone did not 
demonstrate any qualitative or quantitative increased susceptibility in 
the rat and rabbit developmental toxicity studies or the 2-generation 
rat reproduction study. In rabbits and rats, there were no 
developmental effects up to the highest dose tested and in the presence 
of maternal toxicity. In the reproduction study in rats, decreased 
absolute brain weight in F2 female pups occurred at the same dose 
levels as decreased absolute brain weight in F1 parental females.
    In the developmental neurotoxicity (DNT) study in rats, no maternal 
toxicity was observed at doses up to 4,700 ppm (429 mg/kg/day), 
although offspring systemic toxicity, manifested as decreased body 
weight (9-11%) and body weight gain (8-20%) during pre-weaning and 
decreased body weight (4-6%) during post-weaning, occurred at the 
highest dose tested (429 mg/kg/day). The offspring NOAEL of 1,000 ppm 
(92.3 mg/kg/day) indicates an increased susceptibility of offspring. 
Nevertheless, the concern for the increased susceptibility observed in 
the DNT is low because: (1) Of the lack of neurobehavioral or 
neuropathological changes in the offspring at any dose; and (2) the 
endpoints used for the various risk assessment scenarios are much more 
sensitive than that of the decreased bodyweight of the offspring 
occurring at almost half the limit-dose (429 mg/kg/day).
    3. Conclusion. EPA has determined that reliable data show the 
safety of infants and children would be adequately protected if the 
FQPA SF

[[Page 35113]]

were reduced to 1X. That decision is based on the following findings:
    i. The toxicity database for fenamidone is complete.
    ii. There was no evidence of neurotoxicity in the subchronic 
neurotoxicity study submitted for fenamidone. There was evidence of 
neurotoxicity (urination, staining/soiling of the anogenital region, 
mucous in the feces and unsteady gait in females) in the acute 
neurotoxicity study, and EPA used the NOAEL from this study to assess 
acute dietary exposure. There was also evidence of neurotoxicity 
(decreased absolute brain weights) in the 2-generation rat reproduction 
study; however, there was no indication of increased susceptibility of 
offspring with regard to these effects. Finally, there was no evidence 
of neurotoxicity at any dose in the submitted DNT study. Based on the 
results of these studies, EPA concluded that there is no need for 
additional UFs to account for neurotoxicity.
    iii. No qualitative or quantitative increased susceptibility of rat 
or rabbit fetuses to in utero exposure in the developmental toxicity 
studies was observed. There was no qualitative or quantitative 
increased susceptibility in the two generation reproduction study 
(rat). There is low concern for increased susceptibility observed in 
the DNT study for the reasons noted in Unit III.D.2.
    iv. There are no residual uncertainties identified in the exposure 
databases. The dietary food exposure assessments were performed based 
on 100 PCT and maximum or average field trial residue values. EPA made 
conservative (protective) assumptions in the ground and surface water 
modeling used to assess exposure to fenamidone in drinking water. These 
assessments will not underestimate the exposure and risks posed by 
fenamidone.

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. Using the exposure assumptions discussed in this 
unit for acute exposure, the acute dietary exposure from food and water 
to fenamidone will occupy 4.9% of the aPAD for children 1-2 years old, 
the population group receiving the greatest exposure.
    2. Chronic risk. Using the exposure assumptions described in this 
unit for chronic exposure, EPA has concluded that chronic exposure to 
fenamidone from food and water will utilize 56% of the cPAD for 
children 1-2 years old, the population group receiving the greatest 
exposure. There are no residential uses for fenamidone.
    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).
    Short- and intermediate-term adverse effects were identified; 
however, fenamidone is not registered for any use patterns that would 
result in either short- or intermediate-term residential exposure. 
Short- and intermediate-term risk is assessed based on short- and 
intermediate-term residential exposure plus chronic dietary exposure. 
Because there is no short- 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 intermediate-term risk), no further 
assessment of short- or intermediate-term risk is necessary, and EPA 
relies on the chronic dietary risk assessment for evaluating short- and 
intermediate-term risk for fenamidone.
    4. Aggregate cancer risk for U.S. population. Based on the lack of 
evidence of carcinogenicity in two adequate rodent carcinogenicity 
studies, fenamidone 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 fenamidone residues.

IV. Other Considerations

A. Analytical Enforcement Methodology

    Adequate enforcement methodology (liquid chromatographic method 
coupled with tandem mass spectrum detection (LC/MS/MS), Method RPA 
407213) is available to enforce the tolerance expression.
    The method may be requested from: Chief, Analytical Chemistry 
Branch, Environmental Science Center, 701 Mapes Rd., Ft. Meade, MD 
20755-5350; telephone number: (410) 305-2905; email address: 
residuemethods@epa.gov.

B. International Residue Limits

    In making its tolerance decisions, EPA seeks to harmonize U.S. 
tolerances with international standards whenever possible, consistent 
with U.S. food safety standards and agricultural practices. EPA 
considers the international maximum residue limits (MRLs) established 
by the Codex Alimentarius Commission (Codex), as required by FFDCA 
section 408(b)(4). The Codex Alimentarius is a joint United Nations 
Food and Agriculture Organization/World Health Organization food 
standards program, and it is recognized as an international food safety 
standards-setting organization in trade agreements to which the United 
States is a party. EPA may establish a tolerance that is different from 
a Codex MRL; however, FFDCA section 408(b)(4) requires that EPA explain 
the reasons for departing from the Codex level.
    There are Codex MRLs for flowerhead brassicas including broccoli, 
Chinese broccoli, and cauliflower at 4 ppm; cabbage at 0.9 ppm; lettuce 
at 20 ppm; and celery at 40 ppm which are all lower than the proposed 
U.S. tolerances. The U.S. tolerances cannot be harmonized (lowered) 
because following the label use directions could result in residues 
above the Codex MRLs.

C. Revisions to Petitioned-For Tolerances

    The petitioner sought separate tolerances on the subgroups 4-16A at 
60 ppm and 4-15B at 55 ppm. The Agency is establishing the whole group 
tolerance at 60 ppm for group 4-16, in order to harmonize with Canada.

V. Conclusion

    Therefore, tolerances are established for residues of fenamidone in 
or on basil, dried leaves at 200 ppm; basil, fresh leaves at 30 ppm; 
celtuce at 60 ppm; cottonseed subgroup 20C at 0.02 ppm; fennel, 
Florence, fresh leaves and stalk at 60 ppm; kohlrabi at 5.0 ppm; leaf 
petiole vegetable subgroup 22B at 60 ppm; leafy vegetable group 4-16 at 
60 ppm; and the vegetable, Brassica, head and stem, group 5-16 at 5.0 
ppm.
    Additionally, the following existing crop group tolerances are 
being removed since the commodities covered by those crop groups are 
covered by the newly established crop group tolerances: Brassica, head 
and stem subgroup 5A; Brassica leafy greens, subgroup 5B; cotton, 
undelinted seed; and vegetable,

[[Page 35114]]

leafy, except Brassica, group 4. The majority of the commodities in 
subgroups 5A and 5B and group 4 are explicitly included in the new 
group tolerances, but some commodity entries from the existing subgroup 
and group tolerances are not repeated in the new group tolerances. To 
clarify how those commodities remain covered, EPA provides the 
following explanation. First, subgroup 5A includes two commodities that 
are not explicitly covered by other group tolerances: ``cabbage, 
Chinese mustard'' and ``cavalo broccolo''. As EPA discussed in its 
preamble to the proposed rule amending crop groups, 79 FR 68153 (Nov. 
14, 2014), ``cabbage, Chinese mustard'' is not a distinct crop, just a 
general reference to leafy, non-heading Brassica greens, which are 
covered in group 4-16, and ``cavalo broccolo'' is the same species as 
cauliflower, which is covered in group 5-16. Second, subgroup 5B 
includes ``mustard spinach''. In the same preamble document, EPA noted 
that ``mustard spinach'' is one of several names for mustard greens, 
which are covered by the new group 5-16. Third, group 4 includes 
``tampala amaranth'', ``chrysanthemum, edible-leaved'', and ``Indian 
spinach''. Each of these commodity entries are alternative names for 
other commodities still contained in the new group 4-16 and so no 
longer necessary: ``edible-leaved chrysanthemum'' is another name for 
``chrysanthemum garland''; the preferred name for ``tampala amaranth'' 
is ``Chinese amaranth''; and the preferred name for ``Indian spinach'' 
is ``Malabar spinach''. Therefore, residues on commodities listed in 
the existing group tolerances are still covered by the establishment of 
the new group tolerances.
    Lastly, the existing entry for cilantro, leaves is being modified 
to read ``Cilantro, fresh leaves'' in accordance with Agency 
nomenclature.

VI. Statutory and Executive Order Reviews

    This action establishes tolerances under FFDCA section 408(d) 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 action has been 
exempted from review under Executive Order 12866, this action is not 
subject to Executive Order 13211, entitled ``Actions Concerning 
Regulations That Significantly Affect Energy Supply, Distribution, or 
Use'' (66 FR 28355, May 22, 2001) or Executive Order 13045, entitled 
``Protection of Children from Environmental Health Risks and Safety 
Risks'' (62 FR 19885, April 23, 1997). This action 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 FFDCA section 408(d), 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 action directly regulates growers, food processors, food 
handlers, and food retailers, not States or tribes, nor does this 
action alter the relationships or distribution of power and 
responsibilities established by Congress in the preemption provisions 
of FFDCA section 408(n)(4). As such, the Agency has determined that 
this action will not have a substantial direct effect on States or 
tribal governments, on the relationship between the national government 
and the States or tribal governments, or on the distribution of power 
and responsibilities among the various levels of government or between 
the Federal Government and Indian tribes. Thus, the Agency has 
determined that Executive Order 13132, entitled ``Federalism'' (64 FR 
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 action. In addition, this 
action does not impose any enforceable duty or contain any unfunded 
mandate as described under Title II of the Unfunded Mandates Reform Act 
(UMRA) (2 U.S.C. 1501 et seq.).
    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 (NTTAA) (15 U.S.C. 272 note).

VII. Congressional Review Act

    Pursuant to the Congressional Review Act (5 U.S.C. 801 et seq.), 
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 
the rule in the Federal Register. This action is not a ``major rule'' 
as defined by 5 U.S.C. 804(2).
