II. Summary of Petitioned-For Tolerance

    In the Federal Register of July 20, 2011 (76 FR 43231) (FRL-8880-
1), EPA issued a notice pursuant to FFDCA section 408(d)(3), 21 U.S.C. 
346a(d)(3), announcing the filing of a pesticide petition (PP 1E7842) 
by IR-4, 500 College Road East, Suite 201W, Princeton, NJ 08540. The 
petition requested that 40 CFR 180.544 be amended by establishing 
tolerances for residues of the insecticide methoxyfenozide (benzoic 
acid, 3-methoxy-2-methyl-, 2-(3,5-dimethylbenzoyl)-2-(1,1-dimethylethyl 
hydrazide), in or on the raw agricultural commodities fruit, citrus, 
group 10-10 at 1.9 parts per million (ppm); lemon, oil at 45 ppm; 
citrus, oil (except lemon) at 100 ppm; vegetable, root, except sugar 
beet, subgroup 1B at 0.8 ppm; and beet, sugar at 0.5 ppm. In addition, 
the petition proposed that 40 CFR 180.544 be amended by removing the 
tolerance for vegetable, root, subgroup 1A from paragraph (a) and the 
tolerances for fruit, citrus and citrus, oil from paragraph (c). 
Lastly, the petition proposed to revise the tolerance expressions in 40 
CFR 180.544. That notice referenced a summary of the petition prepared 
by Dow AgroSciences LLC, the registrant, which is available in the 
docket, http://www.regulations.gov. There were no comments received in 
response to the notice of filing.
    In the Federal Register of October 27, 2010 (75 FR 66092) (FRL-
8848-3), EPA issued a notice pursuant to FFDCA section 408(d)(3), 21 
U.S.C. 346a(d)(3), announcing the filing of a pesticide petition (PP 
0F7776) by Dow AgroSciences LLC, 9330 Zionsville Road, Indianapolis, IN 
46268. The petition proposed to reestablish tolerances which were 
inadvertently allowed to expire in 2010. The proposed tolerances in 40 
CFR 180.544 are for indirect or inadvertent combined residues of the 
insecticide methoxyfenozide, (benzoic acid, 3-methoxy-2-methyl-, 2-
(3,5-dimethylbenzoyl)-2-(1,1-dimethylethyl) hydrazide) and its 
metabolites RH-117,236 free phenol of methoxyfenozide; 3,5-
dimethylbenzoic acid N-tert-butyl-N'-(3-hydroxy-2-methylbenzoyl) 
hydrazide, RH-151,055 glucose conjugate of RH-117,236; 3,5-
dimethylbenzoic acid N-tert-butyl-N-[3 ([beta]-D-glucopyranosyloxy)-2-
methylbenzoyl]-hydrazide) and RH-152,072 the malonylglycosyl conjugate 
of RH-117,236, in or on the raw agricultural commodities: Vegetable, 
root and tuber, group 1 at 0.1 ppm; vegetable, leaves of root and 
tuber, group 2 at 0.2 ppm; vegetable, bulb, group 3 at 0.2 ppm; 
vegetable, legume, group 6 at 0.1 ppm; vegetable, foliage of legume, 
group 7 at 10 ppm; grain, cereal, forage, fodder, and straw, group 16 
at 10 ppm; grass, forage, fodder and hay, group 17 at 10 ppm; animal 
feed, non-grass, group 18 at 10 ppm; and herb and spice, group 19 at 10 
ppm. That notice referenced a summary of the petition prepared by Dow 
AgroSciences LLC, the registrant, which is available in the docket, 
http://www.regulations.gov. There were no comments received in response 
to the notice of filing.
    Based upon review of the data supporting the petitions, EPA has 
modified the levels at which tolerances are being established for some 
of the commodities. The reasons for these changes are explained in Unit 
IV.C.

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 methoxyfenozide including 
exposure resulting from the tolerances established by this action. 
EPA's assessment of exposures and risks associated with methoxyfenozide 
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.
    Methoxyfenozide is not acutely toxic and not a dermal sensitizer. 
Minimal or no toxic effects were observed in studies in which 
methoxyfenozide was administered by the dermal or inhalation routes of 
exposure.

[[Page 40808]]

    The main target organs in the rat and dog were the liver, thyroid 
and red blood cells (RBC). The most consistent findings across species 
and studies were decreased red blood cell parameters and increased 
liver, thyroid, adrenal and spleen weights. In the rat metabolism 
study, liver contained 2-9% of the administered radioactivity at 
maximum concentration (Cmax), but levels decreased and 
bioaccumulation was not observed. Levels in the blood were negligible. 
The effects of methoxyfenozide on the blood (methemoglobinemia, 
decreased red blood cell parameters, Heinz body formation) are 
consistent with those of other hydrazine compounds.
    Acute and subchronic oral neurotoxicity studies in the rat did not 
show evidence of potential neurotoxicity. In the acute study, decreased 
hindlimb grip strength on Day 0 was reported in males. This finding was 
only observed at the limit dose in males and was not observed in the 
subchronic neurotoxicity study and was therefore not considered 
evidence of neurotoxicity. No clinical signs of toxicity or 
neurohistopathology were observed in other guideline studies.
    No maternal or developmental effects were observed in either the 
rat or rabbit oral developmental toxicity studies. In the rat 2-
generation reproductive toxicity study, parental effects were limited 
to increased liver weight and microscopic periportal hypertrophy. No 
offspring or reproductive toxicity was observed. In a 28-day dietary 
immunotoxicity study in the rat, no immunotoxicity was observed. The 
only observed effect was increased liver weight.
    Dermal effects were not observed in the rat following a 28-day 
exposure period (5 exposure days per week for a total of 20 exposures). 
This finding is consistent with the relatively low dermal absorption of 
2% of the applied dose, observed in an in vivo dermal absorption study 
in rats treated with an 80% wettable powder (WP) formulation product.
    There was no evidence of carcinogenicity in the rat dietary 24-
month chronic toxicity/carcinogenicity study or the mouse dietary 18-
month carcinogenicity study. No mutagenic or clastogenic potential was 
observed in the battery of genotoxicity studies on methoxyfenozide. 
Based on these findings, methoxyfenozide is classified as ``not likely 
to be carcinogenic to humans.''
    Specific information on the studies received and the nature of the 
adverse effects caused by methoxyfenozide 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 document titled ``Methoxyfenozide Human Health 
Risk Assessment'' starting at page 14 in docket ID number EPA-HQ-OPP-
2011-0343.

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://www.epa.gov/pesticides/factsheets/riskassess.htm.
    A summary of the toxicological endpoints for methoxyfenozide used 
for human risk assessment is shown in the Table of this unit.

C. Exposure Assessment

    1. Dietary exposure from food and feed uses. In evaluating dietary 
exposure to methoxyfenozide, EPA considered exposure under the 
petitioned-for tolerances as well as all existing methoxyfenozide 
tolerances in 40 CFR 180.544. EPA assessed dietary exposures from 
methoxyfenozide 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 methoxyfenozide; 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 CSFII. As to residue levels in food, EPA used tolerance level 
residues, Dietary Exposure Evaluation Model (DEEM) (Ver. 7.81) default 
processing factors (as necessary), an empirical processing factor for 
orange juice, and 100 percent crop treated (PCT) for all commodities.
    iii. Cancer. Based on the data summarized in Unit III.A., EPA has 
concluded that methoxyfenozide does not pose a cancer risk to humans. 
Therefore, a dietary exposure assessment for the purpose of assessing 
cancer risk is unnecessary.
    iv. Anticipated residue and PCT information. EPA did not use 
anticipated residue and/or PCT information in the dietary assessment 
for methoxyfenozide. Tolerance level residues and 100 PCT were assumed 
for all food commodities.
    2. Dietary exposure from drinking water. The Agency used screening 
level water exposure models in the dietary exposure analysis and risk 
assessment for methoxyfenozide in drinking water. These simulation 
models take into account data on the physical, chemical, and fate/
transport characteristics of methoxyfenozide. 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 Pesticide Root Zone Model/Exposure Analysis Modeling 
System (PRZM/EXAMS) and Screening Concentration in Ground Water (SCI-
GROW) models the estimated drinking water concentrations (EDWCs) of 
methoxyfenozide for chronic exposures for non-cancer assessments are 
estimated to be 43.4 parts per billion (ppb) for surface water and 4.13 
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 43.4 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).
    Methoxyfenozide is currently registered for the following uses that 
could result in residential exposures: Ornamentals. EPA assessed 
residential exposure using the following assumptions: Adults may be 
exposed to methoxyfenozide from its currently registered use on 
ornamentals. Residential pesticide handlers may be exposed for short-
term durations of exposure (1-30 days) only. The inhalation (short-
term) residential exposure was assessed for a ``homeowner'' mixer/
loader/applicator using a manually pressurized handwand, backpack 
sprayer, or hose-end sprayer.
    Further information regarding EPA standard assumptions and generic 
inputs for residential exposures may be found at http://www.epa.gov/pesticides/trac/science/trac6a05.pdf.
    4. Cumulative effects from substances with a common mechanism of 
toxicity.

[[Page 40810]]

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 methoxyfenozide to share a common mechanism of 
toxicity with any other substances, and methoxyfenozide does not appear 
to produce a toxic metabolite produced by other substances. For the 
purposes of this tolerance action, therefore, EPA has assumed that 
methoxyfenozide 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://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. Based on the results in the 
developmental toxicity studies in rats and rabbits and in the 2-
generation reproduction study in rats, no increased sensitivity of 
fetuses or pups (as compared to adults) was demonstrated for 
methoxyfenozide. There are no concerns or residual uncertainties for 
prenatal/postnatal toxicity following exposure to methoxyfenozide.
    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 methoxyfenozide is complete. Although 
a 28-day inhalation toxicity study has not been submitted, EPA has 
determined that this study is not needed based on a weight of evidence 
approach that considered all of the available hazard and exposure 
information, including the use of a conservative oral POD that results 
in MOEs ranging from 28,000 to 4,100,000 for risk via the inhalation 
route due to residential and occupational exposures. Therefore, there 
is no need for additional UFs to account for missing studies.
    ii. There is no indication that methoxyfenozide is a neurotoxic 
chemical and there is no need for additional UFs to account for 
neurotoxicity.
    iii. There is no evidence that methoxyfenozide results in increased 
susceptibility in in utero rats or rabbits in the prenatal 
developmental studies or in young rats in the 2-generation reproduction 
study.
    iv. There are no residual uncertainties identified in the exposure 
databases. The dietary food exposure assessment utilized 100 PCT and 
tolerance-level residues (established or recommended). EPA made 
conservative (protective) assumptions in the ground and surface water 
modeling used to assess exposure to methoxyfenozide in drinking water. 
These assessments will not underestimate the exposure and risks posed 
by methoxyfenozide.

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, 
methoxyfenozide 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 
methoxyfenozide from food and water will utilize 58% of the cPAD for 
children 1-2 years old the population group receiving the greatest 
exposure. Based on the explanation in Unit III.C.3., regarding 
residential use patterns, chronic residential exposure to residues of 
methoxyfenozide is not expected.
    3. Short-term risk. Short-term aggregate exposure takes into 
account short-term residential exposure plus chronic exposure to food 
and water (considered to be a background exposure level). 
Methoxyfenozide is currently registered for uses that could result in 
short-term residential exposure for adults, and the Agency has 
determined that it is appropriate to aggregate chronic exposure through 
food and water with short-term residential exposures to 
methoxyfenozide.
    Using the exposure assumptions described in this unit for short-
term exposures, EPA has concluded the combined short-term food, water, 
and residential exposures result in aggregate MOEs of 670. Because 
EPA's level of concern for methoxyfenozide is a MOE of 100 or below, 
these MOEs are not of concern.
    4. Intermediate-term risk. Intermediate-term aggregate exposure 
takes into account intermediate-term residential exposure plus chronic 
exposure to food and water (considered to be a background exposure 
level). Because no intermediate-term adverse effect was identified, 
methoxyfenozide is not expected to pose an intermediate-term risk.
    5. Aggregate cancer risk for U.S. population. Based on the lack of 
evidence of carcinogenicity in two adequate rodent carcinogenicity 
studies, methoxyfenozide is not expected to pose a cancer risk to 
humans.
    6. Determination of safety. Based on these risk assessments, EPA 
concludes that there is a reasonable certainty that no harm will result 
to the general population, or to infants and children from aggregate 
exposure to methoxyfenozide residues.

IV. Other Considerations

A. Analytical Enforcement Methodology

    Adequate enforcement methodology (high performance liquid 
chromatography (HPLC), with either tandem mass spectrometric detection 
(LC/MS/MS) or ultraviolet detection (HPLC/UV)) 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.

[[Page 40811]]

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.
    The Codex has established MRLs for methoxyfenozide in or on citrus 
fruits at 0.7 ppm, carrots at 0.5 ppm, and radishes at 0.4 ppm. These 
MRLs are different than the tolerances established for methoxyfenozide 
in the United States. Harmonization of tolerances in the currently 
requested commodities is not possible, as the U.S. and Codex use 
patterns differ potentially resulting in residues in citrus and 
vegetable, root, except sugar beet, subgroup 1B, which includes carrots 
and radishes, under U.S. use patterns that are greater than the 
corresponding Codex MRLs.

C. Revisions to Petitioned-For Tolerances

    EPA is establishing a slightly higher tolerance of 0.90 ppm for 
vegetable, root, except sugar beet, subgroup 1B, than was proposed. The 
0.90 ppm tolerance was calculated using the Organization for Economic 
Co-operation and Development (OECD) tolerance calculation procedure. 
Similarly, EPA is establishing tolerances for citrus commodities that 
are higher than that proposed by IR-4. IR-4 proposed separate 
tolerances for residues in lemon oil and residues in all other citrus 
oils. However, because residues from the citrus field trials are 
similar enough to warrant a crop group tolerance, and a single 
processing factor was used to derive the oil tolerance, EPA is 
establishing a conservative tolerance in citrus oil at 100 ppm, and no 
separate tolerance for residues in lemon oil will be established. 
Tolerances proposed for inadvertent residues will not be established 
for vegetable, root and tuber group 1 at 1 ppm since a tolerances exist 
in Sec.  180.544(a) for subgroups 1A and 1D. Therefore, only a 
tolerance for potato will be established at the Agency determined level 
of 0.02 ppm. Tolerances will not be established for vegetable, bulb, 
group 3 at 0.20 ppm since a tolerance exists in Sec.  180.544(a) for 
subgroup 3-07B. Only a tolerance for onion, bulb, subgroup 3-07A will 
be established at the Agency determined level of 0.10 ppm. Tolerances 
also are not needed for vegetable, legume group 6, grass forage, 
fodder, and hay group 17, since tolerances for these groups exist under 
Sec.  180.544(a). Also, since a tolerance exists in Sec.  180.544(a) 
for coriander, leaves, a tolerance for Herb and spice, group 19, except 
coriander, leaves will be established at a lower, Agency determined 
level of 4.5 ppm.

V. Conclusion

    Therefore, tolerances are established for residues of 
methoxyfenozide (benzoic acid, 3-methoxy-2-methyl-, 2-(3,5-
dimehtylbenzoyl)-2-(1,1-dimethylethyl hydrazide), in or on fruit, 
citrus, group 10-10 at 3.0 ppm; citrus, oil at 100 ppm; vegetable, 
root, except sugar beet, subgroup 1B at 0.90 ppm; and beet, sugar 0.50 
ppm. Also, due to the tolerances established above by this document, 
the following existing tolerance is removed as unnecessary; vegetable, 
root, subgroup 1A. All of the commodities covered by this crop subgroup 
are covered by the tolerances for vegetable, root, except sugar beet, 
subgroup 1B, and beet, sugar. In addition, concurrent with the 
establishment of tolerances for fruit, citrus, group 10-10 at 3.0 ppm 
and citrus, oil at 100 ppm in Sec.  180.544(a), the tolerances for 
fruit, citrus, group 10 (10 ppm) and citrus oil (100 ppm) will be 
removed from Sec.  180.544(c). Tolerances will be established under 
Sec.  180.544(d)(1) for onion, bulb subgroup 3-07A at 0.10 ppm and for 
potato at 0.02 ppm. Tolerances will be established under Sec.  
180.544(d)(2) for grain, cereal, forage, fodder and straw, group 16 
except corn at 6.0 ppm; animal feed, nongrass, group 18, straw at 8.0 
ppm; and herb and spice, group 19, except coriander, leaves at 4.5 ppm.

VI. Statutory and Executive Order Reviews

    This final rule 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 final rule has 
been exempted from review under Executive Order 12866, this final rule 
is not subject to Executive Order 13211, entitled ``Actions Concerning 
Regulations That Significantly Affect Energy Supply, Distribution, or 
Use'' (66 FR 28355, May 22, 2001) or Executive Order 13045, entitled 
``Protection of Children from Environmental Health Risks and Safety 
Risks'' (62 FR 19885, April 23, 1997). This final rule does not contain 
any information collections subject to OMB approval under the Paperwork 
Reduction Act (PRA), 44 U.S.C. 3501 et seq., nor does it require any 
special considerations under Executive Order 12898, entitled ``Federal 
Actions to Address Environmental Justice in Minority Populations and 
Low-Income Populations'' (59 FR 7629, February 16, 1994).
    Since tolerances and exemptions that are established 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 final rule directly regulates growers, food processors, food 
handlers, and food retailers, not States or tribes, nor does this 
action alter the relationships or distribution of power and 
responsibilities established by Congress in the preemption provisions 
of FFDCA section 408(n)(4). As such, the Agency has determined that 
this action will not have a substantial direct effect on States or 
tribal governments, on the relationship between the national government 
and the States or tribal governments, or on the distribution of power 
and responsibilities among the various levels of government or between 
the Federal Government and Indian tribes. Thus, the Agency has 
determined that Executive Order 13132, entitled ``Federalism'' (64 FR 
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).
