SUPPLEMENTARY INFORMATION:

I. Executive Summary

A. Does this action apply to me?

    You may be potentially affected by this action if you are an 
agricultural producer, food manufacturer, or pesticide manufacturer. 
The following list of North American Industrial Classification System 
(NAICS) codes is not intended to be exhaustive, but rather provides a 
guide to help readers determine whether this document might apply to 
them:
     Crop production (NAICS code 111).
     Animal production (NAICS code 112).
     Food manufacturing (NAICS code 311).
     Pesticide manufacturing (NAICS code 32532).
    If you have any questions regarding the applicability of this 
proposed action to a particular entity, consult the person listed under 
FOR FURTHER INFORMATION CONTACT.

B. What is EPA's authority for taking this action?

    EPA is issuing this rulemaking under section 408 of the Federal 
Food, Drug, and Cosmetic Act (FFDCA), 21 U.S.C. 346a. FFDCA section 
408(b)(2)(A)(i) 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.'' FFDCA section 
408(b)(2)(A)(ii) defines

[[Page 49255]]

``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. FFDCA section 408(b)(2)(C) requires EPA to give 
special consideration to exposure of infants and children to the 
pesticide chemical residue in establishing a tolerance and to ``ensure 
that there is a reasonable certainty that no harm will result to 
infants and children from aggregate exposure to the pesticide chemical 
residue . . .

C. How can I file an objection or hearing request?

    Under FFDCA section 408(g), 21 U.S.C. 346a(g), any person may file 
an objection to any aspect of this regulation and may also request a 
hearing on those objections. If you fail to file an objection to the 
final rule within the time period specified in the final rule, you will 
have waived the right to raise any issues resolved in the final rule. 
You must file your objection or request a hearing on this regulation in 
accordance with the instructions provided in 40 CFR part 178. To ensure 
proper receipt by EPA, you must identify docket ID number EPA-HQ-OPP-
2022-0003 in the subject line on the first page of your submission. All 
objections and requests for a hearing must be in writing and must be 
received by the Hearing Clerk on or before January 5, 2026.
    The EPA's Office of Administrative Law Judges (OALJ), in which the 
Hearing Clerk is housed, urges parties to file and serve documents by 
electronic means only, notwithstanding any other particular 
requirements set forth in other procedural rules governing those 
proceedings. See ``Revised Order Urging Electronic Filing and 
Service,'' dated June 22, 2023, which can be found at https://www.epa.gov/system/files/documents/2023-06/2023-06-22%20-%20revised%20order%20urging%20electronic%20filing%20and%20service.pdf. 
Although the EPA's regulations require submission via U.S. Mail or hand 
delivery, the EPA intends to treat submissions filed via electronic 
means as properly filed submissions; therefore, the EPA believes the 
preference for submission via electronic means will not be prejudicial. 
When submitting documents to the OALJ electronically, a person should 
utilize the OALJ e-filing system at https://yosemite.epa.gov/oa/eab/eab-alj_upload.nsf.
    In addition to filing an objection or hearing request with the 
Hearing Clerk as described in 40 CFR part 178, please submit a copy of 
the filing (excluding any Confidential Business Information (CBI)) for 
inclusion in the public docket at https://www.regulations.gov. Follow 
the online instructions for submitting comments. Do not submit 
electronically any information you consider to be CBI or other 
information of which the disclosure is restricted by statute. If you 
wish to include CBI in your request, please follow the applicable 
instructions at https://www.epa.gov/dockets/commenting-epa-dockets#rules and clearly mark the information that you claim to be 
CBI. Information not marked confidential pursuant to 40 CFR part 2 may 
be disclosed publicly by EPA without prior notice.

II. Petitioned For Tolerance

    In the Federal Register of May 20, 2022 (87 FR 30855) (FRL-9410-13-
OCSPP), 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 
1F8954) by Syngenta, P.O. Box 18300, Greensboro, NC 27419. The petition 
requested that 40 CFR part 180 be amended by establishing tolerances 
for residues of the fungicide/nematicide cyclobutrifluram, in or on 
cotton at 0.010 parts per million (ppm); cotton, by-products at 0.010 
ppm; lettuce, romaine at 0.015 ppm; and soybean at 0.010 ppm. That 
document referenced a summary of the petition that was prepared by the 
petitioner and included in the docket. There were no comments received 
in response to the notice of filing.

III. Final Tolerance Action

A. Aggregate Risk Assessment and Determination of Safety

    Consistent with FFDCA section 408(b)(2)(D), and the factors 
specified therein, 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 cyclobutrifluram including exposure resulting 
from the tolerances established by this action. EPA's assessment of 
exposures and risks associated with cyclobutrifluram follows.

B. 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. Cyclobutrifluram is a novel pyridine-3-carboxamide 
nematicide/fungicide with a pesticidal mode of action that functions 
via inhibition of complex II succinate dehydrogenase, but the mammalian 
mode of action is not known at this time. Following the administration 
of cyclobutrifluram, the target organs include the liver (mouse) and 
thyroid (rat). In addition, decreased absolute body weight was observed 
in rats and dogs following subchronic administration of the test 
compound. No adverse effects were observed in the chronic/
carcinogenicity toxicity study in rats and the carcinogenicity toxicity 
study in mice up to the highest doses tested (23/34 mg/kg/day (M/F) and 
48/54 mg/kg/day (M/F), respectively).
    The thyroid is the most sensitive endpoint in the cyclobutrifluram 
toxicity database. Following subchronic exposure of rats to 
cyclobutrifluram, follicular cell hypertrophy in males and females was 
observed after 28- (331 mg/kg/day) and 90-day (187 mg/kg/day) 
exposures. Increased thyroid weights were observed in males of the F1 
generation while follicular cell hypertrophy was observed in both sexes 
of the P generation and males of the F1 generation of the 
multigeneration reproductive toxicity study at 43 mg/kg/day. Maternal 
thyroid hormones levels (T3, T4, and TSH) were measured in the 
developmental rat toxicity study up to and including the highest dose 
tested (250 mg/kg/day) and no adverse changes were observed.
    Treatment-related effects to the liver and spleen (increased 
reticulocytes along with increased spleen weights and extramedullary 
hematopoiesis) were observed in mice following 28-day (338/334 mg/kg/
day (M/F)) and 90-day (249/309 mg/kg/day (M/F)) exposures. Liver 
effects included liver hypertrophy, increased liver weights, increased 
triglycerides, and increased liver enzymes (alkaline phosphatase (ALP) 
and alanine transferase (ALT)) as a suite of effects. Cecum effects 
(increased inflammatory cell infiltration of the lamia propria) were 
observed in rats at 331/485 mg/kg/day (M/F) following 28-day oral 
exposure. Lung effects (alveolar duct wall thickening, increased 
alveolar macrophages, and bronchioles/alveolar wall smooth muscle cell 
hypertrophy) were observed following inhalation exposure for 28 days at 
0.08 mg/L. Following chronic oral exposure of rats and mice to 
cyclobutrifluram, no adverse effects were observed up to the

[[Page 49256]]

highest doses tested (23/31 mg/kg/day). Also, no dermal toxicity 
following 28-day exposure was identified up to and including the limit 
dose in the route specific study.
    No quantitative or qualitative lifestage susceptibility was 
observed in either the developmental or reproductive toxicity studies 
up to the highest doses tested. Thyroid toxicity to the parental 
animals in both the P and F1 generations occurred at the same dose 
level (43/55 mg/kg/day (M/F)) as reproductive toxicity (decreased 
fertility in both sexes of the F1 generation). In the dose range-
finding and definitive development studies for both the rat and rabbit, 
neither maternal toxicity nor developmental toxicity was detected up to 
and including the highest doses tested (250 mg/kg/day (rat) and 125 mg/
kg/day (rabbit)).
    The Agency concluded that the data for the rat and rabbit 
developmental toxicity studies are considered adequate, and there was 
no evidence of neurotoxicity.
    Cyclobutrifluram is classified as ``Not Likely to Be Carcinogenic 
to Humans.'' Cyclobutrifluram exposure did not result in treatment-
related tumors in rats or mice, and there were not biologically or 
statistically significant changes in pre-neoplastic lesions. While both 
sexes of rats and mice could have tolerated higher doses, the dosing 
was considered adequate to assess the carcinogenic potential of 
cyclobutrifluram. There is an extensive database that investigated 
mutagenicity following exposure to cyclobutrifluram or its metabolites. 
Within this battery of genotoxicity testing, cyclobutrifluram and its 
metabolites were negative, demonstrating a low concern for mutagenic 
potential.
    Specific information on the studies received and the nature of the 
adverse effects caused by cyclobutrifluram 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 Cyclobutrifluram. Human Health Risk 
Assessment to Support the Registration of a New Active Ingredient for 
Proposed Uses on Cotton Seed; Soybean Seed; Romaine Lettuce; Turf; 
Ornamentals; and Non-bearing (Juvenile) Fruit and Nut Trees, Vines, and 
Berries (Cyclobutrifluram Human Health Risk Assessment) in docket ID 
number EPA-HQ-OPP-2022-0003.

C. 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 https://www.epa.gov/pesticide-science-and-assessing-pesticide-risks/assessing-human-health-risk-pesticides.
    A summary of the toxicological endpoints and PODs for 
Cyclobutrifluram used for human risk assessment can be found in the 
Cyclobutrifluram Human Health Risk Assessment in docket ID number EPA-
HQ-OPP-2022-0003.

D. Exposure Assessment

    1. Dietary exposure from food and feed uses. In evaluating dietary 
exposure to cyclobutrifluram, EPA considered exposure under the 
petitioned-for tolerances. EPA assessed dietary exposures from 
cyclobutrifluram 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 cyclobutrifluram; 
therefore, a quantitative acute dietary exposure assessment is 
unnecessary.
    ii. Chronic exposure. In conducting the chronic dietary exposure 
assessment EPA used the Dietary Exposure Evaluation Model--Food 
Commodity Intake Database (DEEM-FCID), Version 4.02, which incorporates 
2005-2010 consumption data from United States 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 tolerance equivalent-level residues (cyclobutrifluram 
and the metabolite SYN510275), 100% crop treated assumptions, and 
default processing factors.
    iii. Cancer. Based on the data summarized in Unit III.A., EPA has 
concluded that cyclobutrifluram 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 percent crop treated (PCT) information. 
EPA did not use anticipated residue and/or PCT information in the 
dietary assessment for cyclobutrifluram. Tolerance level residues and/
or 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 cyclobutrifluram in drinking water. These simulation 
models take into account data on the physical, chemical, and fate/
transport characteristics of cyclobutrifluram. Further information 
regarding EPA drinking water models used in pesticide exposure 
assessment can be found at https://www.epa.gov/pesticide-science-and-assessing-pesticide-risks/models-pesticide-risk-assessment.
    Based on the Pesticide Root Zone Model (PRZM5 version 5.02), the 
Variable Volume Water Body Model (VVWM version 1.02), and Pesticide 
Root Zone Model Ground Water (PRZM GW version 1.0), the estimated 
drinking water concentrations (EDWCs) of cyclobutrifluram for acute 
exposures are estimated to be 14.3 parts per billion (ppb) for surface 
water and 108.1 ppb for ground water. Chronic exposures for non-cancer 
assessments are estimated to be 7.96 ppb for surface water and 94.0 ppb 
for ground water. For chronic dietary risk assessment, the water 
concentration value of 94.0 ppb was used to assess the contribution to 
drinking water. Modeled estimates of drinking water concentrations were 
directly entered into the dietary exposure model.
    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). Cyclobutrifluram is 
proposed for registration for the following uses that could result in 
residential exposures:

[[Page 49257]]

lawns and turf. EPA assessed the following residential exposure 
scenarios: Short term residential post-application exposure in children 
1 to less than 2 years old (1<2) from incidental oral exposures on 
treated turf. Further information regarding EPA standard assumptions 
and generic inputs for residential exposures may be found at https://www.epa.gov/pesticide-science-and-assessing-pesticide-risks/standard-operating-procedures-residential-pesticide.
    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 considers ``available information'' concerning the cumulative 
effects of a particular pesticide's residues and ``other substances 
that have a common mechanism of toxicity.''
    Unlike other pesticides for which EPA has followed a cumulative 
risk approach based on a common mechanism of toxicity, EPA has not made 
a common mechanism of toxicity finding as to cyclobutrifluram and any 
other substances. For the purposes of this action, therefore, EPA has 
not assumed that cyclobutrifluram has a common mechanism of toxicity 
with other substances. For information regarding EPA's efforts to 
determine which chemicals have a common mechanism of toxicity and to 
evaluate the cumulative effects of such chemicals, see EPA's website at 
https://www.epa.gov/pesticide-science-and- assessing-pesticide-risks/
pesticide- cumulative-risk-assessment-framework.

E. 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. No evidence of increased 
qualitative or quantitative susceptibility was seen in the rat and 
rabbit developmental toxicity studies up to the highest doses tested or 
in the multigeneration reproduction toxicity 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 cyclobutrifluram is complete.
    ii. There is no indication that cyclobutrifluram is a neurotoxic 
chemical and there is no need for a developmental neurotoxicity study 
or additional UFs to account for neurotoxicity.
    iii. There is no evidence that cyclobutrifluram 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 Agency used high-end assumptions in the dietary exposure 
assessment, including the use of tolerance-level or average field trial 
residues, 100% crop treated assumptions, and upper-bound (protective) 
estimates of potential exposure through drinking water. In addition, 
the residential post-application exposure assessment was conducted 
using chemical-specific turf transferrable residues (TTR) data and the 
Agency's 2012 Residential Standard Operating Procedures (SOPs). The 
exposure estimates for cyclobutrifluram are unlikely to be 
underestimated.

F. 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 cyclobutrifluram 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 
cyclobutrifluram from food and water will utilize 1.9% of the cPAD for 
infants less than 1 year old (<1 year 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 cyclobutrifluram is not expected.
    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).
    Cyclobutrifluram is currently registered for uses that could result 
in short-term residential exposure, and the Agency has determined that 
it is appropriate to aggregate chronic exposure through food and water 
with short-term residential exposures to cyclobutrifluram.
    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 margins of exposure MOEs 
of 1600 for children 1-2 years old. Because EPA's level of concern for 
cyclobutrifluram is an MOE below 30, these MOEs are not of concern.
    Because no intermediate-term residential exposure is expected, an 
intermediate-term aggregate assessment was not conducted.
    4. Aggregate cancer risk for U.S. population. Based on the lack of 
evidence of carcinogenicity in two adequate rodent carcinogenicity 
studies, cyclobutrifluram 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 cyclobutrifluram residues. More detailed information on 
this action can be found in the Cyclobutrifluram Human Health Risk 
Assessment in docket ID EPA-HQ-OPP-2022-0003.

IV. Other Considerations

A. Analytical Enforcement Methodology

    Adequate enforcement methodology as described in the supporting 
documents is available to enforce the tolerance expressions.

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

[[Page 49258]]

(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 not established a MRL for cyclobutrifluram.

C. Effective and Expiration Date(s)

    In general, a tolerance action is effective on the date of 
publication of the final rule in the Federal Register. For actions in 
the final rule that lower or revoke existing tolerances, EPA will set 
an expiration date for the existing tolerance of six months after the 
date of publication of the final rule in the Federal Register, in order 
to allow a reasonable interval for producers in exporting members of 
the World Trade Organization's (WTO's) Sanitary and Phytosanitary (SPS) 
Measures Agreement to adapt to the requirements.

D. Revisions to Petitioned-For Tolerances

    The petitioner-requested commodity definitions for cotton (cotton, 
undelinted seed, and cotton, gin byproducts), lettuce, romaine 
(lettuce, leaf), and soybean (soybean, seed) were updated to Agency-
preferred vocabulary (in parentheses, above) for consistency across 
chemicals. In addition, the Agency is establishing the tolerances at 
higher levels than the petitioner requested for cotton, undelinted seed 
(from 0.010 ppm to 0.02 ppm), cotton, gin byproducts (from 0.010 ppm to 
0.02 ppm), lettuce, leaf (from 0.015 ppm to 0.06 ppm), and soybean, 
seed (from 0.010 ppm to 0.03 ppm) as the recommended residues for 
tolerance enforcement were parent cyclobutrifluram and metabolite 
SYN510275 calculated as parent equivalent. The applicant calculated the 
proposed tolerances using the Organization for Economic Cooperation and 
Development (OECD) MRL calculation procedures with parent only as the 
residue for tolerance enforcement.

V. Conclusion

    Therefore, tolerances are established for residues of 
cyclobutrifluram, in or on cotton, gin byproducts at 0.02 ppm, cotton, 
undelinted seed at 0.02 ppm, lettuce, leaf at 0.06 ppm, and soybean, 
seed at 0.03 ppm.

VI. Statutory and Executive Order Reviews

    Additional information about these statutes and Executive Orders 
can be found at https://www.epa.gov/laws-regulations/laws-and-executive-orders.

A. Executive Order 12866: Regulatory Planning and Review

    This action is exempt from review under Executive Order 12866 (58 
FR 51735, October 4, 1993), because it establishes or modifies a 
pesticide tolerance or a tolerance exemption under FFDCA section 408 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.

B. Executive Order 14192: Unleashing Prosperity Through Deregulation

    Executive Order 14192 (90 FR 9065, February 6, 2025) does not apply 
because actions that establish a tolerance under FFDCA section 408 are 
exempted from review under Executive Order 12866.

C. Paperwork Reduction Act (PRA)

    This action does not impose an information collection burden under 
the PRA, 44 U.S.C. 3501 et seq., because it does not contain any 
information collection activities.

D. Regulatory Flexibility Act (RFA)

    Since tolerance actions 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 RFA, 5 U.S.C. 601 et seq., do not apply to this 
action.

E. Unfunded Mandates Reform Act (UMRA)

    This action does not contain an unfunded mandate of $100 million or 
more (in 1995 dollars and adjusted annually for inflation) as described 
in UMRA, 2 U.S.C. 1531-1538, and does not significantly or uniquely 
affect small governments. The action imposes no enforceable duty on any 
state, local or tribal governments or on the private sector.

F. Executive Order 13132: Federalism

    This action does not have federalism implications as specified in 
Executive Order 13132 (64 FR 43255, August 10, 1999), because it will 
not have substantial direct effects on the states, on the relationship 
between the national government and the states, or on the distribution 
of power and responsibilities among the various levels of government.

G. Executive Order 13175: Consultation and Coordination With Indian 
Tribal Governments

    This action does not have tribal implications as specified in 
Executive Order 13175 (65 FR 67249, November 9, 2000), because it will 
not have substantial direct effects on tribal governments, on the 
relationship between the Federal government and the Indian tribes, or 
on the distribution of power and responsibilities between the Federal 
government and Indian tribes.

H. Executive Order 13045: Protection of Children From Environmental

Sec.  180.729  Cyclobutrifluram; tolerances for residues.

    (a) General. Tolerances are established for residues of the 
nematicide/fungicide cyclobutrifluram, including its metabolites and 
degradates, in or on the plant commodities in table 1 to this paragraph 
(a). Compliance with the tolerance levels specified in table 1 is to be 
determined by measuring the sum of cyclobutrifluram (rel-N-[(1R,2R)-2-
(2,4-dichlorophenyl)cyclobutyl]-2-(trifluoromethyl)-3-
pyridinecarboxamide) and its metabolite 2-trifluoromethyl-nicotinamide, 
calculated as the stoichiometric equivalent of cyclobutrifluram in or 
on plant commodities.
