II. Background and Statutory Findings

    In the Federal Register of July 14, 2006 (71 FR 40102) (FRL-8058-
7), 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 
4F6890) by E.I. DuPont de Nemours and Company, Laurel Run Plaza, P. O. 
Box 80038, Wilmington, DE 19880-0038 and Interregional Research Project 
No. 4 (IR-4), 681 Highway No. 1 South, North Brunswick, NJ 08902. The 
petition requested that 40 CFR 180. 451 be amended by establishing a 
tolerance fo residues of the herbicide tribenuron methyl (methyl 2-
[[[[(4-methoxy-6-methyl-1, 3, ,5-triazin-2-
yl)methylamino]carbonyl]amino]sulfonyl]benzoate, in or on field corn 
and grain sorghum (forage, grain, and stover) rice (grain and straw); 
soybean ,seed; and sunflowers at 0.05.parts per million (ppm). The 
notice referenced a summary of the petition prepared by E.I. DuPont de 
Nemours and Company, the registrant, that has been placed into the 
public docket. A comment was received in response to this notice of 
filing from B. Sachau, 15 Elm Street, Florham Park, NJ 07932. The 
comment and EPA's response to this comment is discussed in Unit IV C 
below.
    During the course of the review the Agency noticed that the name of 
the regulated chemical is incorrect and that the Petition Number for 
the sunflowers tolerance was inadvertently left out of the notice. The 
Agency is correcting these errors at this time. The Agency is also 
updating the commodity listing to agree with current terminology. 
Therefore the proposed tolerances are corrected to read: tolerances are 
established for residues of the herbicide tribenuron methyl, (methyl-2-
[[[[N-(4-methoxy-6-methyl-1, 3, 5-triazin -2-
yl)methylamino]carbonyl]amino]sulfonyl]benzoate) in or on corn, field, 
forage at 0.05 ppm; corn, field, grain at 0.05 ppm; corn, field, stover 
at 0.05 ppm; rice, grain at 0.05 ppm; rice, straw at 0.05 ppm; sorghum, 
grain, forage at 0.05 ppm; sorghum, grain, grain at 0.05 ppm; sorghum, 
grain, stover at 0.05 ppm, soybean, seed at 0.05 ppm (4F6890) and 
sunflower, seed at 0.05 ppm (4E6855).
    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 the FFDCA and a complete 
description of

.


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 of and to 
make a determination on aggregate exposure, consistent with section 
408(b)(2) of FFDCA, for a tolerance for residues of tribenuron methyl, 
(methyl-2-[[[[N-(4-methoxy-6-methyl-1, 3, 5-triazin -2-
yl)methylamino]carbonyl]amino]sulfonyl]benzoate) in or on corn, field, 
forage at 0.05 ppm; corn, field, grain at 0.05 ppm; corn, field, stover 
at 0.05 ppm; rice, grain at 0.05 ppm; rice; straw at 0.05 ppm; sorghum, 
grain, forage at 0.05 ppm; sorghum, grain, grain at 0.05 ppm; sorghum, 
grain, stover at 0.05 ppm, soybean, seed at 0.05 ppm and sunflower, 
seed at 0.05 ppm. EPA's assessment of exposures and risks associated 
with establishing the 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. Specific information on the studies received and the nature 
of the toxic effects caused by tribenuron methyl 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 in Unit 
III. A. of the final rule published in the Federal Register of 
September 22, 2004 (69 FR 56711) (FRL-7679-5).

B. Toxicological Endpoints

    For hazards that have a threshold below which there is no 
appreciable risk, the dose at which 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 LOAEL 
of concern are identified 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, and 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/pesticides/health/human.htm.

    A summary of the toxicological endpoints for tribenuron methyl used 
for human risk assessment is discussed in Unit III.B. of the final rule 
published in the Federal Register of September 22, 2004 (69 FR 56711) 
(FRL-7679-5).

C. Exposure Assessment

    1. Dietary exposure from food and feed uses. Tolerances have been 
established (40 CFR 180.451) for the residues of tribenuron methyl, in 
or on a variety of raw agricultural commodities. No tolerances for meat 
product, eggs, or milk are established. Risk assessments were conducted 
by EPA to assess dietary exposures from tribenuron methyl 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 effect attributable to a 
single dose was observed in any studies in the toxicology database for 
tribenuron methyl. As a result, no acute dietary endpoint was 
identified and no acute risk assessment was performed.
    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 Intakes by Individuals 
(CSFII), and accumulated exposure to the chemical for each commodity. 
The following assumptions were made for the chronic exposure 
assessments: tolerance level residues and 100% crop treated (CT). No 
empirical processing factors were used. A DEEM (Version 7.81) default 
processing factor was used for corn syrup. Anticipated residues or 
estimates of percent crop treated (PCT) were not used.
    iii. Cancer. Tribenuron methyl is classified as a Group C (possible 
human carcinogen) because of the increased incidence of mammary gland 
adenocarcinomas in female Sprague-Dawley rats. Tribenuron methyl was 
not shown to be mutagenic in any tests conducted. EPA considers the 
chronic risk assessment to be protective of any potential risk of 
carcinogenicity. Further discussion is found in Unit III.C. of the 
final rule published in the Federal Register of September 22, 2004, 69 
FR 56711 (FRL-7679-5).
    2. Dietary exposure from drinking water. The Agency lacks 
sufficient monitoring exposure data to complete a comprehensive dietary 
exposure analysis and risk assessment for tribenuron methyl 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 tribenuron methyl. Further information regarding EPA 
drinking water models used in pesticide exposure assessment can be 
found at http://www.epa.gov/oppefed/models/water/index.htm.

    Based on the first index reservoir screening tool (FIRST) and 
screening concentration in ground water (SCI-GROW) models, the 
estimated drinking water concentrations (EDWCs) of tribenuron methyl 
for acute exposures are estimated to be 4.1 parts per billion (ppb) for 
surface water and 6.8 ppb for ground water. The EDWCs for chronic 
exposures are estimated to be 2.7 ppb for surface water and 6.8 ppb for 
ground water.
    Modeled estimates of drinking water concentrations were directly 
entered into the dietary exposure model (DEEM-FCID). For the chronic 
dietary risk assessment the higher ground water value of 6.8 ppb was 
used.
    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)Tribenuron methyl 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 the 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

[[Page 11787]]

based on a common mechanism of toxicity, EPA has not made a common 
mechanism of toxicity finding as to tribenuron methyl and any other 
substances and tribenuron methyl 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 tribenuron methyl 
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 
special FQPA safety factors, as appropriate.
    2. Prenatal and postnatal sensitivity. Developmental and 
reproductive toxicity studies in rats and rabbits indicated no 
increased susceptibility (quantitative or qualitative) following in 
utero or prenatal and/or postnatal exposure to tribenuron methyl.
    3. Conclusion. EPA determined that reliable data show that it would 
be safe for infants and children to reduce the FQPA safety factor to 
1X. That decision is based on the following findings.
    i. The toxicity data base for tribenuron methyl is complete. The 
impact of tribenuron methyl on the nervous system has been specially 
evaluated in neurotoxicity studies. There was no evidence of 
neurotoxicity or neuropathology seen in the acute, subchronic, chronic 
or reproductive studies. Therefore, a developmental neurotoxicity study 
is required for tribenuron methyl.
    ii. The available data from the developmental and reproductive 
toxicity studies do not indicate a potential susceptibility of infants 
and children to tribenuron methyl.
    iii. There are no residual uncertainties identified in the exposure 
databases. The dietary food assessments were performed based on 100% CT 
and tolerance level residues. Conservative ground water estimates were 
used in the risk assessment. This assessment will not underestimate the 
exposure and risks posed by tribenuron methyl.

E. Aggregate Risks and Determination of Safety

    1. Acute risk. No toxic effect attributable to a single dose was 
observed in any studies in the toxicology database. As a result, no 
acute risk is expected.
    2. Chronic risk. Using the exposure assumptions described in this 
unit for chronic exposure, EPA has concluded that exposure to 
tribenuron methyl from food and water will utilize 4.7% of the cPAD for 
the U.S. population, 9.8% of the cPAD for all infants (< 1 year old), 
and 9.1% of the cPAD for children 3-5 years old. There are no 
residential uses for tribenuron methyl that result in chronic 
residential exposure to tribenuron methyl. EPA does not expect the 
aggregate exposure to exceed 100% of the cPAD.
    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).
    Tribenuron methyl is not registered for use on any sites that would 
result in residential exposure. Therefore, the aggregate risk is the 
sum of the risk from food and water, which does not exceed the Agency's 
level of concern.
    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).
    Tribenuron methyl is not registered for use on any sites that would 
result in residential exposure. Therefore, the aggregate risk is the 
sum of the risk from food and water, which does not exceed the Agency's 
level of concern.
    5. Aggregate cancer risk for U.S. population. The Agency considers 
the chronic risk assessment, making use of the cPAD, to be protective 
of any aggregate cancer risk. See Unit III. E.2. Therefore, the 
aggregate risk is not expected to exceed the Agency's level of concern.
    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 tribenuron methyl residues.

IV. Other Considerations

A. Analytical Enforcement Methodology

    Adequate enforcement methodology (including high performance liquid 
chromatography (HPLC) with photo-conductivity and liquid chromatography 
with detection via electrospray mass spectroscopy (LC/MS)) are 
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; e-mail address: residuemethods@epa.gov.

B. International Residue Limits

    No Mexican or Codex Maximum Residue Levels (MRLs) have been 
established for tribenuron methyl. Canadian MRLs have been established 
for tribenuron methyl on certain crops; however, no MRLs have been 
established for corn, field, forage; corn, field, grain; corn, field, 
stover; rice, grain; rice, straw; sorghum, grain, forage; sorghum, 
grain, grain; sorghum, grain, stover; soybean, seed; or sunflower, 
seed, therefore no questions of compatibility exist for these 
commodities.

C. Response to Comments

    A comment was received from Ms. B. Sachau in response to the notice 
of filing. Ms. Sachau stated that the chemical should not be 
manufactured or sold. Ms. Sachau based her conclusion on the following: 
eye irritation potential, effects on the liver and kidney, and its 
carcinogenic potential. Ms. Sachau also questioned the availability of 
testing for this chemical in combination with other chemicals in use 
today.
    The effects on the kidney and liver were the basis of the chronic 
reference dose (cRfD) and cPAD used for the chronic dietary risk 
assessment. As discussed in Unit III. E.2, EPA does not expect the 
aggregate exposure to exceed 100% of the cPAD which does not exceed the 
Agency's level of concern. After review of available data, the Agency 
considers the chronic risk

[[Page 11788]]

assessment, making use of the cPAD, to be protective of any aggregate 
cancer risk. Ms. Sachau did not submit any scientific information to 
support a revision of Agency conclusions.
    EPA generally does not require companies to conduct studies to 
evaluate the potential for synergistic effects from exposure to 
combinations of chemical exposure. Such testing rarely shows any kind 
of interaction (synergistic or antagonistic), and there are a nearly 
infinite number of possible combinations, making the cost of 
indiscriminate testing prohibitively high.
    Because synergism does not occur often, the scientific community 
believes that exposure to multiple chemicals is best assessed by 
looking the effects caused by exposure to each chemical individually. 
The only exception to that is when people are exposed to multiple 
chemicals that share a common mechanism of toxicity. Then the effects 
of exposure to multiple chemicals are expected to be additive, adjusted 
for the relative toxicity of the different chemicals. This is done 
through Agency cumulative risk assessments, which are discussed in Unit 
III.C.4. of this document. Ms. Sachau did not submit any scientific 
information to support a revision of Agency conclusions.

V. Conclusion

    Therefore, the tolerances are established for residues of 
tribenuron methyl, (methyl-2-[[[[N-(4-methoxy-6-methyl-1, 3, 5-triazin 
-2-yl)methylamino]carbonyl]amino]sulfonyl]benzoate) in or on corn, 
field, forage at 0.05 ppm; corn, field, grain at 0.05 ppm; corn, field, 
stover at 0.05 ppm; rice, grain at 0.05 ppm; rice; straw at 0.05 ppm; 
sorghum, grain, forage at 0.05 ppm; sorghum, grain, grain at 0.05 ppm; 
sorghum, grain, stover at 0.05 ppm, soybean, seed at 0.05 ppm and 
sunflower, seed 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 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).
