II. Background and Statutory Findings

    In the Federal Register of August 25, 2006 (71 FR 50412) (FRL-8084-
8), 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 
7F4851) by Dow AgroSciences LLC, 9330 Zionville Road, Indianapolis, IN 
46268-1054. The petition requested that 40 CFR 180.468 be amended by 
establishing a tolerance for residues of the herbicide flumetsulam, N-
(2,6-difluorophenyl)-5-methyl-(1,2,4)-triazolo-[1,5-a]-pyrimidine-2-
sulfonamide, in or on beans (dry) at 0.05 parts per million (ppm). That 
notice included a summary of the petition prepared by the registrant. 
There were no comments received in response to the notice of filing.
    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. . . 
.''
    EPA performs a number of analyses to determine the risks from 
aggregate exposure to pesticide residues. For further discussion of the 
regulatory requirements of section 408 of FFDCA and a complete 
description of the risk assessment process, see http://www.epa.gov/fedrgstr/EPA-PEST/1997/November/Day-26/p30948.htm
.

III. Aggregate Risk Assessment and Determination of Safety

    Consistent with 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 and to make 
a determination on aggregate exposure, consistent with section 
408(b)(2) of FFDCA, for a tolerance for residues of flumetsulam on 
beans (dry) at 0.05 ppm ppm. EPA's assessment of exposures and risks 
associated with establishing the tolerance 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. Specific information on the studies received and the nature 
of the toxic effects caused by flumetsulam 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
, Docket OPP-2004-0317.

B. Toxicological Endpoints

    For hazards that have a threshold below which there is no 
appreciable

[[Page 58516]]

risk, the dose at which no adverse effects are observed (the NOAEL) 
from the toxicology study identified as appropriate for use in risk 
assessment is used to estimate the toxicological level of concern 
(LOC). However, the lowest dose at which adverse effects of concern are 
identified (the LOAEL) is sometimes used for risk assessment if no 
NOAEL was achieved in the toxicology study selected. An uncertainty 
factor (UF) is applied to reflect 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.
    The linear default risk methodology (Q*) is the primary method 
currently used by the Agency to quantify non-threshold hazards such as 
cancer. The Q* approach assumes that any amount of exposure will lead 
to some degree of cancer risk, estimates risk in terms of the 
probability of occurrence of additional cancer cases. More information 
can be found on the general principles EPA uses in risk 
characterization at http://www.epa.gov/fedrgstr/EPA-PEST/1997/November/Day-26/p30948.htm
.

    A summary of the toxicological endpoints for flumetsulam used for 
human risk assessment is discussed in the docket OPP-2004-0317, for the 
Notice published in the Federal Register of September 24, 2004 (69 FR 
57281-57284) (FRL-7680-7).

C. Exposure Assessment

    1. Dietary exposure from food and feed uses. Tolerances have been 
established (40 CFR 180.468) for the residues of flumetsulam, in or on 
a variety of raw agricultural commodities, including field corn grain, 
fodder, and forage, and soybean. Risk assessments were conducted by EPA 
to assess dietary exposures from flumetsulam 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 
flumetsulam; 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 software with 
the Food Commodity Intake Database (DEEM-FCID\TM\), which incorporates 
food consumption data as reported by respondents in the USDA 1994-1996 
and 1998 Nationwide Continuing Surveys of Food Intake by Individuals 
(CSFII), and accumulated exposure to the chemical for each commodity. 
The following assumptions were made for the chronic exposure 
assessments: Tolerance level residue values, 100% crop treated, and the 
highest estimated chronic drinking water concentration were used.
    iii. Cancer. Flumetsulam is classified as a ``Group E'' pesticide 
(evidence of non-carcinogenicity to humans).
    2. Dietary exposure from drinking water. The Agency lacks 
sufficient monitoring exposure data to complete a comprehensive dietary 
exposure analysis and risk assessment for flumetsulam in drinking 
water. Because the Agency does not have comprehensive monitoring data, 
drinking water concentration estimates are made by reliance on 
simulation or modeling taking into account data on the physical 
characteristics of flumetsulam.
    Based on the Pesticide Root Zone Model/Exposure Analysis Modeling 
System (PRZM/EXAMS) and Screening Concentrations in Groundwater (SCI-
GROW) models, the estimated environmental concentrations (EECs) of 
flumetsulam for chronic exposures are estimated to be 0.59 parts per 
billion (ppb) for surface water and 0.823 ppb for ground 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).
    Flumetsulam is not registered for use on any sites 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.''
    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 flumetsulam and any other 
substances and flumetsulam does not appear to produce a toxic 
metabolite produced by other substances. For the purposes of this 
tolerance action, therefore, EPA has not assumed that flumetsulam 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 the policy statements released by EPA's Office of 
Pesticide Programs concerning common mechanism determinations and 
procedures for cumulating effects from substances found to have a 
common mechanism on EPA's website at http://www.epa.gov/pesticides/cumulative
.

D. Safety Factor for Infants and Children

    1. In general. Section 408 of FFDCA provides that EPA shall apply 
an additional tenfold 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 data base on toxicity and exposure 
unless EPA determines based on reliable data that a different margin of 
safety will be safe for infants and children. Margins of safety are 
incorporated into EPA risk assessments either directly through use of a 
MOE analysis or through using uncertainty (safety) factors in 
calculating a dose level that poses no appreciable risk to humans. In 
applying this provision, EPA either retains the default value of 10X 
when reliable data do not support the choice of a different factor, or, 
if reliable data are available, EPA uses a different additional safety 
factor value based on the use of traditional uncertainty factors and/or 
FQPA safety factors, as appropriate.
    2. Prenatal and postnatal sensitivity. Neither acceptable 
Developmental Toxicity Studies in rats or rabbits revealed increased 
susceptibility of the fetus to flumetsulam after in utero exposure. 
Similarly, the results of the Two Generation Reproduction Study did not 
indicate an increased susceptibility to flumetsulam in utero or during 
postnatal exposure.
    3. Conclusion. There is a complete toxicity data base for 
Flumetsulam and exposure data are complete or are estimated based on 
data that reasonably accounts for potential exposures. EPA determined 
that the 10X SF to protect infants and children may be reduce to 1X. 
The FQPA factor is reduced to 1X because:
    i. There is a complete toxicity data base for flumetsulam;
    ii. Toxicity studies with flumetsulam showed no evidence of 
increased sensitivity in the young; and
    iii. Exposure data are complete or are estimated based on data that 
reasonably accounts for potential exposures. The exposure assessment 
was found to

[[Page 58517]]

reasonably account for potential exposures because the dietary food 
exposure assessment utilizes proposed tolerance level residues and 100% 
crop treatment information for all commodities and the dietary drinking 
water assessment utilizes values generated by model and associated 
modeling parameters which are designed to provide health protective, 
high-end estimates of water concentrations.

E. Aggregate Risks and Determination of Safety

    1. Acute dietary risk. No acute hazards were identified following a 
single oral exposure (dose) of flumetsulam. No effects in the 
developmental toxicity studies in the rabbit or rat were attributed to 
a single oral exposure during gestation. Therefore, Flumetsulam is not 
expected to pose an acute risk.
    2. Chronic dietary risk. Using the exposure assumptions described 
in this unit for chronic exposure, EPA has concluded that exposure to 
flumetsulam from food will utilize < 1% of the cPAD for the U.S. 
population, all infant and children population subgroups, and women of 
childbearing age (females 13 - 49 years old). In addition, there is 
potential for chronic dietary exposure to Flumetsulam in drinking 
water. After quantitatively incorporating the modeled Estimated 
Drinking Water Concentrations (EDWC) for surface water (0.59 ppb) and 
ground water (0.82 ppb), the chronic aggregated dietary exposure does 
not exceed 1% of the cPAD, and is well below the Agency's Level of 
Concern.
    3. Short-term risk. Short-term aggregate exposure takes into 
account residential exposure plus chronic exposure to food and water 
(considered to be a background exposure level).
    Flumetsulam is not registered for use on any sites that would 
result in residential exposure. Therefore, calculation of short-term 
aggregate risk is not appropriate.
    4. Intermediate-term risk. Intermediate-term aggregate exposure 
takes into account residential exposure plus chronic exposure to food 
and water (considered to be a background exposure level).
    Flumetsulam is not registered for use on any sites that would 
result in residential exposure. Therefore, calculation of intermediate-
term aggregate risk is not appropriate.
    5. Aggregate cancer risk for U.S. population. Flumetsulam is 
classified as a ``Group E'', i.e., there is evidence of non-
carcinogenicity for humans. Consequently, the conduct of a cancer risk 
assessment is not appropriate.
    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, and to infants and children from aggregate 
exposure to Flumetsulam residues.

IV. Other Considerations

A. Analytical Enforcement Methodology

    The available analytical enforcement method (GC/MS method) is 
considered adequate for tolerance enforcement of Flumetsulam in plant 
commodities. The method is available, and has been submitted for 
inclusion in the Pesticide Analytical Manual. In the mean time, 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; e-mail address: 
residuemethods@epa.gov.

B. International Residue Limits

    There are no Codex, Canadian, or Mexican maximum residue limits 
(MRLs) for Flumetsulam; therefore, no questions of compatibility with 
U.S. tolerances exist.

V. Conclusion

    Therefore, the tolerance is established for residues of 
flumetsulam, N-(2,6-difluorophenyl)-5-methyl-(1,2,4)-triazolo-[1,5-a]-
pyrimidine-2-sulfonamide, in or on beans (dry) at 0.05 ppm.

VI. Statutory and Executive Order Reviews

    This final rule establishes a tolerance 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 rule has been 
exempted from review under Executive Order 12866 due to its lack of 
significance, this rule is not subject to Executive Order 13211, 
Actions Concerning Regulations That Significantly Affect Energy Supply, 
Distribution, or Use (66 FR 28355, May 22, 2001). 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., or 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). 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); or OMB review or any Agency action under Executive 
Order 13045, entitled Protection of Children from Environmental Health 
Risks and Safety Risks (62 FR 19885, April 23, 1997). 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). 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. In addition, the Agency has determined that this 
action will not have a substantial direct effect on 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, as specified in Executive Order 13132, entitled Federalism 
(64 FR 43255, August 10, 1999). Executive Order 13132 requires EPA to 
develop an accountable process to ensure ``meaningful and timely input 
by State and local officials in the development of regulatory policies 
that have federalism implications.'' ``Policies that have federalism 
implications'' is defined in the Executive order to include regulations 
that 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.'' This final rule directly regulates growers, food 
processors, food handlers and food retailers, not States. This action 
does not alter the relationships or distribution of power and 
responsibilities established by Congress in the preemption provisions 
of section 408(n)(4) of FFDCA. For these same reasons, the Agency has 
determined that this rule does not have any ``tribal implications'' as 
described in Executive Order 13175, entitled Consultation and 
Coordination with Indian Tribal Governments (65 FR 67249, November 6, 
2000). Executive Order 13175, requires EPA to develop an accountable 
process to ensure ``meaningful and timely input by tribal officials in 
the development of

[[Page 58518]]

regulatory policies that have tribal implications.'' ``Policies that 
have tribal implications'' is defined in the Executive order to include 
regulations that have ``substantial direct effects on one or more 
Indian tribes, 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.'' This rule will not 
have substantial direct effects on tribal governments, on the 
relationship between the Federal Government and Indian tribes, or on 
the distribution of power and responsibilities between the Federal 
Government and Indian tribes, as specified in Executive Order 13175. 
Thus, Executive Order 13175 does not apply to this rule.

VII. Congressional Review Act

    The Congressional Review Act, 5 U.S.C. 801 et seq., as added by the 
Small Business Regulatory Enforcement Fairness Act of 1996, generally 
provides that before a rule may take effect, the agency promulgating 
the rule must submit a rule report, which includes a copy of the rule, 
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).
