II. Summary of Petitioned-For Tolerance

    In the Federal Register of July 19, 2013 (78 FR 43115) (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 
2F8131) by E.I. du Pont de Nemours and Company, 1007 Market Street, 
Wilmington, DE 19898. The petition requested that 40 CFR 180.478 be 
amended by establishing tolerances for residues of the herbicide 
rimsulfuron, N-((4,6-dimethoxypyrimidin-2-yl)aminocarbonyl)-3-
(ethylsulfonyl)-2-pyridinesulfonamide, in or on sorghum, forage; 
sorghum, grain; and sorghum, stover at 0.01 parts per million (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, http://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. EPA has also revised the 
chemical name nomenclature for rimsulfuron in the tolerance expression. 
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

[[Page 66802]]

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 rimsulfuron including exposure 
resulting from the tolerances established by this action. EPA's 
assessment of exposures and risks associated with rimsulfuron 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.
    Rimsulfuron 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 subchronic and 
chronic toxicity studies in rats, toxic effects included decreased body 
weight, decreased body weight gain, increased relative liver and 
absolute kidney weights, and diuresis. In the subchronic study in mice, 
increased red blood cell and hemoglobin, and decreased body weight gain 
and food efficiency were observed. In the chronic study in mice, 
decreased body weight, increased incidences of dilation and cysts in 
the glandular stomach, and degeneration of the testicular artery and 
tunica albuginea were observed. In the subchronic study in dogs, 
diuresis was indicated by urinary volume, platelet concentration, and 
kidney weights accompanied by decreased urinary osmolality. In the 
chronic study in dogs, increased absolute liver and kidney weights, 
increased seminiferous tubule degeneration, and increased number of 
spermatid giant cells present in epididymides in males were observed. 
In both sexes, decreases in mean body weights and body weight gain, and 
increases in serum cholesterol levels, alkaline phosphatase activity, 
absolute liver weight, relative liver, and relative kidney weights were 
observed.
    In the developmental toxicity study in rats, no toxicity was seen 
at the highest dose tested. In the developmental toxicity study in 
rabbits (in which both maternal and fetal death were observed), and in 
the 2-generation reproduction toxicity study in rats (in which 
decreases in body weight gain were observed in both parents and 
offspring), developmental and offspring effects were seen in the 
presence of maternal/systemic toxicity at the same dose levels.
    In the acute and subchronic neurotoxicity studies, no evidence of 
neurotoxicity was observed. In the immunotoxicity study, no evidence of 
immunosuppression was observed. In the mutagenicity studies, no 
evidence of clastogenicity or mutagenicity was observed. Rimsulfuron is 
classified as ``Not Likely to be Carcinogenic to Humans'' based on lack 
of evidence of carcinogenicity in rats and mice studies.
    Specific information on the studies received and the nature of the 
adverse effects caused by rimsulfuron 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 ``Rimsulfuron. Human Health Risk 
Assessment for Proposed Section 3 Use on Acetolactase Synthase (ALS) 
Tolerant Grain Sorghum'' at pp. 27-32 in docket ID number EPA-HQ-OPP-
2013-0035.

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 the NOAEL and the LOAEL are identified. 
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 http://www.epa.gov/pesticides/factsheets/riskassess.htm.
    A summary of the toxicological endpoints for rimsulfuron 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 rimsulfuron, EPA considered exposure under the petitioned-
for tolerances as well as all existing rimsulfuron tolerances in 40 CFR 
180.478. EPA assessed dietary exposures from rimsulfuron 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 rimsulfuron; 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 
rimsulfuron 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 rimsulfuron.
    iii. Cancer. Based on the data summarized in Unit III.A., EPA has 
concluded that rimsulfuron 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 rimsulfuron. 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 rimsulfuron in drinking water. These simulation models 
take into account data on the physical, chemical, and fate/transport 
characteristics of rimsulfuron. Further information regarding EPA 
drinking water models used in pesticide exposure assessment can be 
found at http://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 rimsulfuron 
for chronic exposures for non-cancer assessments are estimated to be 
0.38 parts per billion (ppb) for surface water and 19.7 ppb for ground 
water.
    Modeled estimates of drinking water concentrations were directly 
entered into the dietary exposure model. For chronic dietary risk 
assessment, the water concentration of value 19.7 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). Rimsulfuron 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 
rimsulfuron to share a common mechanism of toxicity with any other 
substances, and rimsulfuron does not appear to produce a toxic 
metabolite produced by other substances. For the purposes of this 
tolerance action, therefore, EPA has assumed that rimsulfuron 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 http://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 Federal 
Quality Protection Act Safety Factor (FQPA 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. In the developmental 
toxicity study in rats, no developmental toxicity was seen at the 
highest dose tested. In the developmental toxicity study in rabbits and 
in the 2-generation reproductive study in rats, developmental and 
offspring toxicity were seen only in the presence of maternal/systemic 
toxicity. Consequently, there is no evidence of quantitative or 
qualitative increased susceptibility following pre- and/or postnatal 
exposures.
    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 rimsulfuron is complete.
    ii. There is no indication that rimsulfuron is a neurotoxic 
chemical and there is no need for a developmental neurotoxicity study 
or additional Uncertainty Factor (UF) to account for neurotoxicity.
    iii. There is no evidence that rimsulfuron 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 rimsulfuron in drinking water. These assessments 
will not underestimate the exposure and risks posed by rimsulfuron.

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

[[Page 66804]]

and no acute dietary endpoint was selected. Therefore, rimsulfuron 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 
rimsulfuron from food and water will utilize 1.4% of the cPAD for all 
infants less than 1-year old, the population group receiving the 
greatest exposure. There are no residential uses for rimsulfuron.
    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).
    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, rimsulfuron 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 rimsulfuron 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: 
[email protected]ov.

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 rimsulfuron.

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''. The tolerance expression is revised to reflect the 
preferred chemical name for rimsulfuron using CAS nomenclature.

V. Conclusion

    Therefore, tolerances are established for residues of rimsulfuron, 
N-[[(4,6-dimethoxy-2-pyrimidinyl)amino]carbonyl]-3-(ethylsulfonyl)-2-
pyridinesulfonamide, in or on sorghum, grain, forage; sorghum, grain, 
grain; and sorghum, grain, stover at 0.01 ppm.

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 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 tolerances 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).
