II. Summary of Petitioned-For Tolerance

    In the Federal Register of July 19, 2013 (78 FR 43117) (FRL-9392-
9), 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 
2F8132) by E.I. du Pont de Nemours and Company, 1007 Market Street, 
Wilmington, DE 19898. The petition requested that 40 CFR 180.454 be 
amended by establishing tolerances for residues of the herbicide 
nicosulfuron, 3-pyridinecarboxamide, 2-((((4,6-dimethoxypyrimidin-2-
yl)aminocarbonyl)aminosulfonyl))-N,N-dimethyl, in or on sorghum, forage 
at 0.4 parts per million (ppm); sorghum, grain at 0.8 ppm; and sorghum, 
stover at 0.05 ppm. That document referenced a summary of the petition 
prepared by E.I. du Pont de Nemours and Company, the registrant, which 
is available in the docket, https://www.regulations.gov. There were no 
comments received in response to the notice of filing.
    Based upon review of the data supporting the petition, EPA has 
revised the proposed commodity definitions, revised the proposed 
tolerance level for ``sorghum, grain, forage'', and corrected the 
typographical error in the chemical name of nicosulfuron in the 
tolerance expression. Also, EPA has removed the expired emergency 
exemption tolerances for Bermuda grass, forage and Bermuda grass, hay. 
The reasons for these changes are explained in Unit IV.C.

III. Aggregate Risk Assessment and Determination of Safety

    Section 408(b)(2)(A)(i) of FFDCA allows EPA to establish a 
tolerance (the legal limit for a pesticide chemical residue in or on a 
food) only if EPA determines that the tolerance is ``safe.'' Section 
408(b)(2)(A)(ii) of FFDCA defines ``safe'' to mean that ``there is a 
reasonable certainty that no harm will result from aggregate exposure 
to the pesticide chemical residue, including all anticipated dietary 
exposures and all other exposures for which there is reliable 
information.'' This includes exposure through drinking water and in 
residential settings, but does not include occupational exposure. 
Section 408(b)(2)(C) of FFDCA requires EPA to give special 
consideration to exposure of infants and children to the pesticide 
chemical residue in establishing a tolerance and to ``ensure that there 
is a reasonable certainty that no harm will result to infants and 
children from aggregate exposure to the pesticide chemical residue. . . 
.''
    Consistent with FFDCA section 408(b)(2)(D), and the factors 
specified in FFDCA section 408(b)(2)(D), EPA has reviewed the available 
scientific data and other relevant information in support of this 
action. EPA has sufficient data to assess the hazards of and to make a 
determination on aggregate exposure for nicosulfuron including exposure 
resulting from the tolerances established by this action. EPA's 
assessment of exposures and risks associated with nicosulfuron 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.
    Nicosulfuron has low acute toxicity by oral, dermal, and inhalation 
routes of exposure. It is moderately irritating to the eye, non-
irritating to the skin, and is not a skin sensitizer. In repeated dose 
studies by the oral route, nicosulfuron is minimally toxic, and rodents 
are particularly insensitive to its effects. Chronic dietary 
administrations to rats and mice did not produce any adverse effects at 
the highest dose tested (HDT). Chronic dietary administration to dogs 
produced mild effects (increased relative liver and kidney weights of 
males) at the HDT.
    Nicosulfuron showed no developmental effects in rats, and no 
adverse effects were observed in the rat reproductive study. In the 
rabbit developmental study, abortions occurred at the doses that caused 
other maternal toxicity effects. There are no indications of neurotoxic 
or immunotoxic effects elicited by nicosulfuron in animal studies; this 
includes recently submitted acute and subchronic neurotoxicity studies 
and an immunotoxicity study. There is no evidence of mutagenicity.
    Nicosulfuron is classified as ``Not Likely to be Carcinogenic to 
Humans'' based on lack of evidence of carcinogenicity in rats and mice 
studies and lack of mutagenic effects in the in vitro and in vivo 
genotoxicity studies.
    Specific information on the studies received and the nature of the 
adverse effects caused by nicosulfuron 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 ``Nicosulfuron: Human Health Risk 
Assessment for Proposed Use on ALS Inhibitor Tolerant Sorghum,'' pp. 
24-27 in docket ID number EPA-HQ-OPP-2013-0034.

B. Toxicological Points of Departure/Levels of Concern

    Once a pesticide's toxicological profile is determined, EPA 
identifies toxicological points of departure (POD) and levels of 
concern to use in evaluating the risk posed by human exposure to the 
pesticide. For hazards that have a threshold below which there is no 
appreciable risk, the toxicological POD is used as the basis for 
derivation of reference values for risk assessment. PODs are developed 
based on a careful analysis of the doses in each toxicological study to 
determine the dose at which no adverse effects are observed (the NOAEL) 
and the lowest dose at which adverse effects of concern are identified 
(the LOAEL). Uncertainty/safety factors are used in conjunction with 
the POD to calculate a safe exposure level--generally referred to as a 
population-adjusted dose (PAD) or a reference dose (RfD)--and a safe 
margin of exposure (MOE). For non-threshold risks, the Agency assumes 
that any amount of exposure will lead to some degree of risk. Thus, the 
Agency estimates risk in terms of the probability of an occurrence of 
the adverse effect expected in a lifetime. For more information on the 
general principles EPA uses in risk characterization and a complete 
description of the risk assessment process, see https://

    A summary of the toxicological endpoints for nicosulfuron used for 
human risk assessment is shown in Table 1 of this unit.

C. Exposure Assessment

    1. Dietary exposure from food and feed uses. In evaluating dietary 
exposure to nicosulfuron, EPA considered exposure under the petitioned-
for tolerances as well as all existing nicosulfuron tolerances in 40 
CFR 180.454. EPA assessed dietary exposures from nicosulfuron 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 nicosulfuron; therefore, a 
quantitative acute dietary exposure assessment is unnecessary.
    ii. Chronic exposure. In conducting the chronic dietary exposure 
assessment EPA used the food consumption data from the USDA's 2003-2008 
National Health and Nutrition Examination Survey, What We Eat in 
America (NHANES/WWEIA). As to residue levels in food, EPA assumed that 
nicosulfuron residues were present at tolerance levels in all 
commodities for which tolerances have been established or proposed, and 
that 100% of those crops were treated with nicosulfuron.
    iii. Cancer. Based on the data summarized in Unit III.A., EPA has 
concluded that nicosulfuron 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 nicosulfuron. 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 nicosulfuron in drinking water. These simulation models 
take into account data on the physical, chemical, and fate/transport 
characteristics of nicosulfuron. 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 Pesticide Root Zone Model Ground Water (PRZM-
GW), the estimated drinking water concentrations (EDWCs) of 
nicosulfuron for chronic exposures for non-cancer assessments are 
estimated to be 2.8 ppb for surface water and 19.2 ppb for ground 
water. Based on the Screening Concentration in Ground Water (SCI-GROW) 
model, the EDWC of nicosulfuron for chronic exposures for non-cancer 
assessments are estimated to be 1.42 ppb.
    Modeled estimates of drinking water concentrations were directly 
entered into the dietary exposure model. For chronic dietary risk 
assessment, the water concentration value of 19.2 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). Nicosulfuron 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 nicosulfuron to share a common mechanism of 
toxicity with any other substances, and nicosulfuron does not appear to 
produce a toxic metabolite produced by other substances. For the 
purposes of this tolerance action, therefore, EPA has assumed that 
nicosulfuron does not have a common mechanism of toxicity with other 
substances. For information regarding EPA's efforts to determine which 
chemicals have a common mechanism of toxicity and to evaluate the 
cumulative effects of such chemicals, see EPA's Web site at 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. No evidence of increased 
sensitivity or susceptibility in the developing or young animal was 
observed in the current database. No treatment-related

[[Page 68264]]

effects were seen for maternal or developmental toxicity up to and 
including the HDT in the rat prenatal developmental study, and no 
adverse effects were noted in the rat reproductive study. Although 
increases in abortions and post-implantation losses were observed in 
the rabbit developmental study, those effects occurred at the same 
doses as other maternal toxicity, indicating that they were a secondary 
effect of maternal toxicity, rather than a developmental or 
reproductive effect.
    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 nicosulfuron is complete.
    ii. There is no indication that nicosulfuron 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 nicosulfuron 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 PCT and tolerance-level residues. EPA made conservative 
(protective) assumptions in the ground and surface water modeling used 
to assess exposure to nicosulfuron in drinking water. These assessments 
will not underestimate the exposure and risks posed by nicosulfuron.

E. Aggregate Risks and Determination of Safety

    EPA determines whether acute and chronic dietary pesticide 
exposures are safe by comparing aggregate exposure estimates to the 
acute PAD (aPAD) and chronic PAD (cPAD). For linear cancer risks, EPA 
calculates the lifetime probability of acquiring cancer given the 
estimated aggregate exposure. Short-, intermediate-, and chronic-term 
risks are evaluated by comparing the estimated aggregate food, water, 
and residential exposure to the appropriate PODs to ensure that an 
adequate MOE exists.
    1. Acute risk. An acute aggregate risk assessment takes into 
account acute exposure estimates from dietary consumption of food and 
drinking water. No adverse effect resulting from a single oral exposure 
was identified and no acute dietary endpoint was selected. Therefore, 
nicosulfuron 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 
nicosulfuron from food and water will utilize <1% of the cPAD for the 
general U.S. population and all population subgroups including infants 
and children. There are no residential uses for nicosulfuron.
    3. Short- and intermediate-term risks. 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). Because there are no 
residential uses, no short- or intermediate-term aggregate risk 
assessments were conducted.
    4. Aggregate cancer risk for U.S. population. Based on the lack of 
evidence of carcinogenicity in two adequate rodent carcinogenicity 
studies, nicosulfuron 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 nicosulfuron residues.

IV. Other Considerations

A. Analytical Enforcement Methodology

    Adequate enforcement methodology (Method DuPont-32277, a high 
performance liquid chromatography with tandem mass spectroscopy (HPLC/
MS/MS)) is available to enforce the tolerance expression. The method 
may be requested from: Chief, Analytical Chemistry Branch, 
Environmental Science Center, 701 Mapes Rd., Ft. Meade, MD 20755-5350; 
telephone number: (410) 305-2905; email address: 
residuemethods@epa.gov.

B. International Residue Limits

    In making its tolerance decisions, EPA seeks to harmonize U.S. 
tolerances with international standards whenever possible, consistent 
with U.S. food safety standards and agricultural practices. EPA 
considers the international maximum residue limits (MRLs) established 
by the Codex Alimentarius Commission (Codex), as required by FFDCA 
section 408(b)(4). The Codex Alimentarius is a joint United Nations 
Food and Agriculture Organization/World Health Organization food 
standards program, and it is recognized as an international food safety 
standards-setting organization in trade agreements to which the United 
States is a party. EPA may establish a tolerance that is different from 
a Codex MRL; however, FFDCA section 408(b)(4) requires that EPA explain 
the reasons for departing from the Codex level.
    The Codex has not established MRLs for nicosulfuron.

C. Revisions to Petitioned-For Tolerances

    The Agency is revising the proposed commodity definitions of 
``sorghum, forage'' to ``sorghum, grain, forage''; ``sorghum, grain'' 
to ``sorghum, grain, grain''; and ``sorghum, stover'' to ``sorghum, 
grain, stover'' for consistency with EPA's Food and Feed Commodity 
Vocabulary. The proposed tolerance level of 0.4 ppm for ``sorghum, 
forage'' is revised to 0.3 ppm for ``sorghum, grain, forage'' based on 
analysis of the residue field trial data using the Organization for the 
Economic Cooperation and Development's tolerance calculation procedure. 
The tolerance expression is revised to correct the typographical error 
in the chemical name for nicosulfuron.

V. Conclusion

    Therefore, tolerances are established for residues of nicosulfuron, 
2-[[[[(4,6-dimethoxy-2-pyrimidinyl)amino] carbonyl]amino]sulfonyl]-N,N-
dimethyl-3-pyridinecarboxamide, including its metabolites and 
degradates, in or on sorghum, grain, forage at 0.3 ppm; sorghum, grain, 
grain at 0.8 ppm; and sorghum, grain, stover at 0.05 ppm.
    In addition, as a housekeeping measure, the Agency is removing the 
expired emergency exemption tolerances on ``Bermuda grass, forage'' and 
``Bermuda grass, hay''. The tolerances expired on December 31, 2011.

VI. Statutory and Executive Order Reviews

    This final rule establishes tolerances under FFDCA section 408(d) 
in response to a petition submitted to the Agency. The Office of 
Management and Budget (OMB) has exempted these types of actions from 
review under Executive Order 12866, entitled ``Regulatory Planning and 
Review'' (58 FR 51735, October 4, 1993). Because this final rule has 
been exempted from review under Executive Order 12866, this final rule 
is not subject to Executive Order 13211, entitled ``Actions Concerning 
Regulations That Significantly Affect Energy Supply, Distribution, or 
Use'' (66 FR 28355, May 22, 2001) or Executive Order 13045, entitled 
``Protection of Children from Environmental Health

[[Page 68265]]

Risks and Safety Risks'' (62 FR 19885, April 23, 1997). This final rule 
does not contain any information collections subject to OMB approval 
under the Paperwork Reduction Act (PRA) (44 U.S.C. 3501 et seq.), nor 
does it require any special considerations under Executive Order 12898, 
entitled ``Federal Actions to Address Environmental Justice in Minority 
Populations and Low-Income Populations'' (59 FR 7629, February 16, 
1994).
    Since tolerances and exemptions that are established on the basis 
of a petition under FFDCA section 408(d), such as the tolerance in this 
final rule, do not require the issuance of a proposed rule, the 
requirements of the Regulatory Flexibility Act (RFA) (5 U.S.C. 601 et 
seq.), do not apply.
    This final rule directly regulates growers, food processors, food 
handlers, and food retailers, not States or tribes, nor does this 
action alter the relationships or distribution of power and 
responsibilities established by Congress in the preemption provisions 
of FFDCA section 408(n)(4). As such, the Agency has determined that 
this action will not have a substantial direct effect on States or 
tribal governments, on the relationship between the national government 
and the States or tribal governments, or on the distribution of power 
and responsibilities among the various levels of government or between 
the Federal Government and Indian tribes. Thus, the Agency has 
determined that Executive Order 13132, entitled ``Federalism'' (64 FR 
43255, August 10, 1999) and Executive Order 13175, entitled 
``Consultation and Coordination with Indian Tribal Governments'' (65 FR 
67249, November 9, 2000) do not apply to this final rule. In addition, 
this final rule does not impose any enforceable duty or contain any 
unfunded mandate as described under Title II of the Unfunded Mandates 
Reform Act of 1995 (UMRA) (2 U.S.C. 1501 et seq.).
    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) (15 U.S.C. 272 note).

VII. Congressional Review Act

    Pursuant to the Congressional Review Act (5 U.S.C. 801 et seq.), 
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 
the rule in the Federal Register. This action is not a ``major rule'' 
as defined by 5 U.S.C. 804(2).
