II. Petition for Tolerance

    In the Federal Register of July 25, 2007 (72 FR 40877) (FRL-8137-
1), 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 
7E7199) by Interregional Research Project Number 4 (IR-4), 500 College 
Road East, Suite 201W, Princeton NJ 08540. The petition requested that 
40 CFR 180.598 be amended by establishing tolerances for residues of 
the insecticide novaluron, 1-[3-chloro-4-(1,1,2-trifluoro-2-
trifluoromethoxyethoxy)phenyl]-3-(2,6-difluorobenzoyl)urea, in or on 
sugarcane, cane at 0.50 parts per million (ppm); tomato at 0.40 ppm; 
and tomato, paste at 0.80 ppm. That notice referenced a summary of the 
petition prepared on behalf of IR-4 by Makhteshim-Agan of North 
America, Inc., the registrant, which is available to the public in the 
docket, https://www.regulations.gov. Comments were received on the 
notice of filing. EPA's response to these comments is discussed in Unit 
IV.C.
    Based upon review of the data supporting the petition, EPA has 
increased the tolerance on tomato to 1.0 ppm and determined that a 
separate tolerance on tomato, paste is not needed. The reasons for 
these changes are explained in Unit IV.D.

[[Page 74979]]

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 the petitioned-for 
tolerances for residues of novaluron on sugarcane, cane at 0.50 ppm and 
tomato at 1.0 ppm. EPA's assessment of exposures and risks associated 
with establishing 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.
    Novaluron has low acute toxicity via the oral, dermal and 
inhalation routes of exposure. It is not an eye or skin irritant and is 
not a dermal sensitizer. In subchronic and chronic toxicity studies, 
novaluron primarily produced hematotoxic effects such as 
methemoglobinemia, decreased hemoglobin, decreased hematocrit and 
decreased red blood corpuscles (RBCs or erythrocytes) associated with 
increased erythropoiesis.
    There was no maternal or developmental toxicity seen in the rat and 
rabbit developmental toxicity studies up to the limit doses. In the 2-
generation reproductive toxicity study in rats, both maternal and 
offspring toxicity were evidenced by spleenomegaly. Reproductive 
toxicity (decreases in epididymal sperm counts and increased age at 
preputial separation in the F1 generation) was observed only in males.
    Novaluron does not appear to be a potent neurotoxicant. Signs of 
neurotoxicity were seen in the acute neurotoxicity study in rats but 
only at the limit dose of 2,000 milligrams/kilogram/day (mg/kg/day). 
Neurotoxic signs seen in this study included clinical signs 
(piloerection, fast/irregular breathing), functional observation 
battery (FOB) parameters (head swaying, abnormal gait) and 
neuropathology (sciatic and tibial nerve degeneration). No signs of 
neurotoxicity or neuropathology were observed in the subchronic 
neurotoxicity study in rats at doses up to 1,752 mg/kg/day in males and 
2,000 mg/kg/day in females or in any other subchronic or chronic 
toxicity study in rats, mice or dogs.
    There was no evidence of carcinogenic potential in either the rat 
or mouse carcinogenicity studies and no evidence of mutagenic activity 
in the submitted mutagenicity studies, including a bacterial 
(Salmonella, E. coli) reverse mutation assay, an in vitro mammalian 
chromosomal aberration assay, an in vivo mouse bone-marrow micronucleus 
assay and bacterial DNA damage or repair assay. Based on the results of 
these studies, EPA has classified novaluron as ``not likely to be 
carcinogen to humans.''
    Specific information on the studies received and the nature of the 
adverse effects caused by novaluron 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 https://
www.regulations.gov in document PP 7E7199 Novaluron in/on Sugarcane and 
Tomato. Health Effects Division (HED) Risk Assessment, pages 24 to 27 
in docket ID number EPA-HQ-OPP-2007-0438.

B. Toxicological Endpoints

    For hazards that have a threshold below which there is no 
appreciable risk, a toxicological point of departure (POD) is 
identified as the basis for derivation of reference values for risk 
assessment. The POD may be defined as the highest dose at which the 
NOAEL are observed in the toxicology study identified as appropriate 
for use in risk assessment. However, if a NOAEL cannot be determined, 
the LOAEL concern are identified or a benchmark dose (BMD) approach is 
sometimes used for risk assessment. Uncertainty/safety factors (UFs) 
are used in conjunction with the POD to take into account uncertainties 
inherent in the extrapolation from laboratory animal data to humans and 
in the variations in sensitivity among members of the human population 
as well as other unknowns. Safety is assessed for acute and chronic 
dietary risks by comparing aggregate food and water exposure to the 
pesticide to the acute population adjusted dose (aPAD) and chronic 
population adjusted dose (cPAD). The aPAD and cPAD are calculated by 
dividing the POD by all applicable UFs. Aggregate short-term, 
intermediate-term, and chronic-term risks are evaluated by comparing 
food, water, and residential exposure to the POD to ensure that the 
margin of exposure (MOE) called for by the product of all applicable 
UFs is not exceeded. This latter value is referred to as the Level of 
Concern (LOC).
    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 
greater than that 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 https://www.epa.gov/
pesticides/factsheets/riskassess.htm.
    A summary of the toxicological endpoints for novaluron used for 
human risk assessment can be found at https://www.regulations.gov in 
document PP-7E7199 Novaluron in/on Sugarcane and Tomato. Health Effects 
Division (HED) Risk Assessment, pages 10 to 11 in docket ID number EPA-
HQ-OPP-2007-0438.

C. Exposure Assessment

    1. Dietary exposure from food and feed uses. In evaluating dietary 
exposure to novaluron, EPA considered exposure under the petitioned-for 
tolerances as well as all existing novaluron tolerances in 40 CFR 
180.598. EPA assessed dietary exposures from novaluron 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 novaluron; therefore, a 
quantitative acute dietary exposure assessment is unnecessary.
    ii. Chronic exposure. In conducting the chronic dietary exposure 
assessment

[[Page 74980]]

EPA used the food consumption data from the United States Department of 
Agriculture (USDA) 1994-1996 and 1998 Continuing Surveys of Food 
Intakes by Individuals (CSFII). As to residue levels in food, EPA 
incorporated anticipated residues (average field trial residues) for 
some commodities, including the new commodities (sugarcane and 
tomatoes); empirical processing factors for apple juice (translated to 
pear juice); and DEEM (ver 7.81) default processing factors for the 
remaining processed commodities. In estimating dietary exposure from 
secondary residues in livestock, EPA relied on anticipated residues for 
meat and milk commodities but used tolerance-level residues for poultry 
commodities. 100 percent crop treated (PCT) was assumed for all 
existing and new uses of novaluron.
    iii. Cancer. Based on the results of carcinogenicity studies in 
rats and mice, EPA has classified novaluron as ``not likely to be 
carcinogenic to humans;'' therefore, a quantitative cancer exposure 
assessment is unnecessary.
    iv. Anticipated residue information. 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 residues of concern in 
drinking water are novaluron and its chlorophenyl urea and 
chloroaniline degradates. The Agency used screening level water 
exposure models in the dietary exposure analysis and risk assessment 
for novaluron and its degradates in drinking water. These simulation 
models take into account data on the physical, chemical, and fate/
transport characteristics of novaluron. Further information regarding 
EPA drinking water models used in pesticide exposure assessment can be 
found at https://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 
novaluron, chlorophenyl urea and chloroaniline for chronic exposures 
for non-cancer assessments are estimated to be 1.8 parts per billion 
(ppb), 0.86 ppb and 2.6 ppb, respectively, for surface water and 0.0055 
ppb, 0.0045 ppb and 0.0090 ppb, respectively, for ground water.
    Modeled estimates of drinking water concentrations were directly 
entered into the dietary exposure model. The highest drinking water 
concentrations were estimated for surface water. Of the three EDWC 
values for surface water, the chronic EDWC for the terminal metabolite, 
chloroaniline, is the highest (assuming 100 percent molar conversion 
from parent to aniline). This is consistent with the expected 
degradation pattern for novaluron. Therefore, for chronic dietary risk 
assessment, the water concentration value for chloroaniline of 2.6 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). Novaluron 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 novaluron to share a common mechanism of toxicity 
with any other substances, and novaluron does not appear to produce a 
toxic metabolite produced by other substances. For the purposes of this 
tolerance action, therefore, EPA has assumed that novaluron 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 website at https://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 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 prenatal and postnatal 
toxicology database for novaluron includes rat and rabbit prenatal 
developmental toxicity studies and a 2-generation reproduction toxicity 
study in rats. There was no evidence of increased quantitative or 
qualitative susceptibility following in utero exposure of rats or 
rabbits in the developmental toxicity studies and no evidence of 
increased quantitative or qualitative susceptibility of offspring in 
the reproduction study. Neither maternal nor developmental toxicity was 
seen in the developmental studies up to the limit doses. In the 
reproduction study, offspring and maternal toxicity (increased absolute 
and relative spleen weights) were similar and occurred at the same 
dose; and reproductive effects (decreases in epididymal sperm counts 
and increased age at preputial separation in the F1 generation) 
occurred at a higher dose than that which resulted in maternal 
toxicity.
    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 novaluron is complete, except for 
immunotoxicity testing. EPA began requiring functional immunotoxicity 
testing of all food and non-food use pesticides on December 26, 2007. 
Since this requirement went into effect after the tolerance petition 
was submitted, these studies are not yet available for novaluron. In 
the absence of specific immunotoxicity studies, EPA has evaluated the 
available novaluron toxicity data to determine whether an additional 
database uncertainty factor is needed to account for potential 
immunotoxicity. There was no evidence of adverse effects on the organs 
of the

[[Page 74981]]

immune system at the LOAEL in any study novaluron. In addition, 
novaluron does not belong to a class of chemicals (e.g., the 
organotins, heavy metals, or halogenated aromatic hydrocarbons) that 
would be expected to be immunotoxic. Based on the above considerations, 
EPA does not believe that conducting a special series 870.7800 
immunotoxicity study will result in a point of departure less than the 
NOAEL of 0.011 mg/kg/day used in calculation the cPAD for novaluron, 
and therefore, an additional database uncertainty factor is not needed 
to account for potential immunotoxicity.
    ii. There were signs of neurotoxicity in the acute neurotoxicity 
study in rats, including clinical signs (piloerection, fast/irregular 
breathing), functional observation battery (FOB) parameters (head 
swaying, abnormal gait) and neuropathology (sciatic and tibial nerve 
degeneration). However, the signs observed were not severe and were 
seen only at the limit dose (2,000 mg/kg/day); further, the 
neuropathological effects that were seen at the limit dose also 
occurred in a few untreated control animals. No signs of neurotoxicity 
or neuropathology were observed in the subchronic neurotoxicity study 
in rats at doses up to 1,752 mg/kg/day in males, and 2,000 mg/kg/day in 
females or in any other subchronic or chronic toxicity study in rats, 
mice or dogs, including the developmental and reproduction studies. 
Therefore, novaluron does not appear to cause significant neurotoxicant 
effects, and there is no need for a developmental neurotoxicity study 
or additional UFs to account for neurotoxicity.
    iii. There is no evidence that novaluron 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 assessments were performed based 
on 100% CT and tolerance-level or anticipated residues derived from 
reliable residue field trials. EPA made conservative (protective) 
assumptions in the ground and surface water modeling used to assess 
exposure to novaluron in drinking water. Residential exposures are not 
expected. These assessments will not underestimate the exposure and 
risks posed by novaluron.

E. Aggregate Risks and Determination of Safety

    EPA determines whether acute and chronic pesticide exposures are 
safe by comparing aggregate exposure estimates to the aPAD and cPAD. 
The aPAD and cPAD represent the highest safe exposures, taking into 
account all appropriate SFs. EPA calculates the aPAD and cPAD by 
dividing the POD by all applicable UFs. For linear cancer risks, EPA 
calculates the probability of additional cancer cases given the 
estimated aggregate exposure. Short-term, intermediate-term, and 
chronic-term risks are evaluated by comparing the estimated aggregate 
food, water, and residential exposure to the POD to ensure that the MOE 
called for by the product of all applicable UFs is not exceeded.
    1. Acute risk. An acute aggregate risk assessment takes into 
account exposure estimates from acute 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, 
novaluron 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 
novaluron from food and water will utilize 74% of the cPAD for children 
1 to 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 novaluron 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). Novaluron is 
not registered for any use patterns that would result in residential 
exposure. Therefore, the short-term aggregate risk is the sum of the 
risk from exposure to novaluron through food and water and will not be 
greater than the chronic aggregate risk.
    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). Novaluron is not registered for any use patterns that would 
result in intermediate-term residential exposure. Therefore, the 
intermediate-term aggregate risk is the sum of the risk from exposure 
to novaluron through food and water, which has already been addressed, 
and will not be greater than the chronic aggregate risk.
    5. Aggregate cancer risk for U.S. population. EPA has classified 
novaluron as ``not likely to be carcinogenic to humans.''Novaluron is 
not expected to pose a cancer risk.
    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 novaluron residues.

IV. Other Considerations

A. Analytical Enforcement Methodology

    Adequate enforcement methodology (a gas chromatography/electron-
capture detection (GC/ECD) method; and a high pressure liquid 
chromatography/ultraviolate detection (HPLC/UV) method) is available to 
enforce the tolerance expression. The methods may be requested from: 
Chief, Analytical 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

    No Canadian or Mexican MRLs have been established for novaluron on 
the sugarcane or tomato commodities. A CODEX MRL is established for 
novaluron (fat soluble) on tomato at 0.02 ppm, significantly below the 
U.S. tolerance being established by this regulation (1.0 ppm). The U.S. 
tolerance is based on a different use pattern, including both a higher 
application rate (12.8x higher) and shorter pre-harvest interval (PHI) 
(2 days vs. 7 days). For these reasons, the U.S. tolerance cannot be 
harmonized with the CODEX MRL at this time.

C. Response to Comments

    EPA received comments from a private citizen complaining that she 
was unable to open the ``proposal'' at https://www.regulations.gov. If 
by ``proposal,'' the commenter is referring to the registrant's notice 
of filing, EPA notes that it is available in the docket in two common 
file formats, MicroSoft Word and Portable Document Format (PDF) and 
cannot explain the commenter's inability to open it. User support is 
available for anyone having trouble using the regulations website by 
calling 1-877-ERUL HLP (1-877-378-5457) or by using the Web form link 
provided under ``Contact Us.''

D. Revisions to Petitioned-For Tolerances

    Based upon review of the data supporting the petition, EPA 
determined that the proposed tolerance on tomato should be increased to 
1.0 ppm and that a separate tolerance on tomato paste is not needed. 
EPA revised the tolerance level for tomato based on analyses of both 
field- and greenhouse-

[[Page 74982]]

grown residue trials using the Agency's Tolerance Spreadsheet in 
accordance with the Agency's Guidance for Setting Pesticide Tolerances 
Based on Field Trial Data. The tolerance level of 1.0 ppm is based on 
the spreadsheet results for greenhouse-grown tomatoes, the cropping 
scenario that resulted in the higher recommended tolerance. The 
submitted tomato processing data indicate that residues of novaluron 
are not likely to concentrate in puree but may concentrate slightly in 
paste. Based on the processing factor (1.1x) for paste and the highest 
average field trial (HAFT) residue of 0.365 ppm from the tomato trials, 
residues of novaluron in paste are not expected to exceed the tolerance 
for tomato (1.0 ppm); therefore, no tolerances for tomato processed 
commodities are needed.
    The tolerance expression at 40 CFR 180.598 uses the International 
Union of Pure and Applied Chemistry (IUPAC) nomenclature for novaluron 
(1-[3-chloro-4-(1,1,2-trifluoro-2-trifluoro-methoxyethoxy)phenyl]-3-
(2,6-difluorobenzoyl)urea). Since it is EPA's policy to use the 
Chemical Abstracts Service (CAS) nomenclature in tolerance expressions, 
EPA is revising the tolerance expression to reflect the correct CAS 
designation for novaluron (N-[[[3-chloro-4-[1,1,2-trifluoro-2-
(trifluoromethoxy)ethoxy]phenyl]amino]carbonyl]-2,6-difluorobenzamide). 
EPA has determined that it is reasonable to make this change final 
without prior proposal and opportunity for comment, because public 
comment is not necessary, in that the change has no substantive effect 
on the tolerance, but rather is a minor change in scientific 
nomenclature consistent with accepted Agency policy and practice.

V. Conclusion

    Therefore, tolerances are established for residues of novaluron, N-
[3-chloro-4-[1,1,2-trifluoro-2-
(trifluoromethoxy)ethoxy]phenyl]amino]carbonyl]-2,6-difluorobenzamide, 
in or on sugarcane, cane at 0.50 ppm and tomato at 1.0 ppm.
    A time-limited tolerance of 0.15 ppm was established for residues 
of novaluron on sugarcane, cane in connection with a FIFRA section 18 
emergency exemption granted by EPA. This tolerance (set to expire on 
12/31/09) is superseded by the higher tolerance being established on 
sugarcane, cane and is no longer needed. Therefore, the time-limited 
tolerance is being revoked.

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 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) (Public Law 104-4).
    This action does not involve any technical standards that would 
require Agency consideration of voluntary consensus standards pursuant 
to section 12(d) of the National Technology Transfer and Advancement 
Act 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).
