II. Summary of Petitioned-for Tolerance

    In the Federal Register of October 25, 2013 (78 FR 63938) (FRL-
9901-96), 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 
3F8196) by K-I Chemical U.S.A. Inc. c/o Landis International, Inc., 
P.O. Box 5126, Valdosta, GA 31603-5126. The petition requested that 40 
CFR 180.659 be amended by increasing the tolerance for residues of the 
herbicide, pyroxasulfone, [3-[[[5-(difluoromethoxy)-1-methyl-3-
(trifluoromethyl)-1H-pyrazol-4-yl]methyl]sulfonyl]-4,5-dihydro-5,5-
dimethylisoxazole] and its metabolite 5-difluoromethoxy-1-methyl-3-
trifluoromethyl-1 H-pyrazol-4-carboxylic acid (M3) calculated as the 
stoichiometric equivalent of pyroxasulfone, in or on corn, field, grain 
from 0.015 to 0.02 parts per million (ppm); and also increasing the 
tolerance for residues of pyroxasulfone, [3-[[[5-(difluoromethoxy)-1-
methyl-3-(trifluoromethyl)-1H-pyrazol-4-yl]methyl]sulfonyl]-4,5-
dihydro-5,5-dimethylisoxazole] and its metabolites 5-difluoromethoxy-1-
methyl-3-trifluoromethyl-1 H-pyrazol-4-ylmethanesulfonic acid (M1), 5-
difluoromethoxy-1-methyl-3-trifluoromethyl-1 H-pyrazol-4-carboxylic 
acid (M3), and 5-difluoromethoxy-3-trifluoromethyl-1 H-pyrazol-4-yl) 
methanesulfonic acid (M25) calculated as the stoichiometric equivalent 
of pyroxasulfone in or on corn, field, forage from 0.06 to 0.09 ppm. 
The amended tolerances were sought to cover residues that may be found 
on corn following use of pyroxasulfone with an adjuvant. That document 
referenced a summary of the petition prepared by K-I Chemical U.S.A. 
Inc. c/o Landis International, Inc., the registrant, which is available 
in the docket, http://www.regulations.gov. There were no comments 
received in response to the notice of filing.

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 pyroxasulfone, including 
exposure resulting from the tolerances established by this action. 
EPA's assessment of exposures and risks associated with pyroxasulfone 
follows.

A. Toxicological Profile

    In the Federal Register of July 31, 2013 (78 FR 46274) (FRL-9393-
6), EPA published a final rule (2013 rulemaking) establishing certain 
tolerances for residues of the herbicide pyroxasulfone and its 
metabolites based on EPA's conclusion that aggregate exposure to 
pyroxasulfone is safe for the general population, including infants and 
children. Since the 2013 rulemaking, there have been no additional 
tolerance actions for pyroxasulfone, nor has the toxicity profile for 
pyroxasulfone changed. Specific information on the studies reviewed for 
that rulemaking and the nature of the adverse effects caused by 
pyroxasulfone, as well as the no-observed-adverse-effect-level (NOAEL) 
and the lowest-observed-adverse-effect-level (LOAEL) from the toxicity 
studies are discussed in the 2013 rulemaking which can be found in 
docket ID number EPA-HQ-OPP-2012-0439.

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 http://www.epa.gov/pesticides/factsheets/riskassess.htm. A summary of the toxicological 
endpoints for pyroxasulfone used for human risk assessment is also 
discussed in Unit III.B of the final rule published in the Federal 
Register of February 29, 2012 (77 FR 12207) (FRL-9334-2).

C. Exposure Assessment

    1. Dietary exposure from food and feed uses. In evaluating dietary 
exposure to pyroxasulfone, EPA conducted a new dietary exposure and 
risk assessment that considered exposure under the petitioned-for 
tolerances as well as all existing pyroxasulfone tolerances in 40 CFR 
180.659. EPA assessed dietary exposures from pyroxasulfone 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. Such effects were identified 
for pyroxasulfone. In estimating acute dietary exposure, EPA used food 
consumption information from the United States Department of 
Agriculture's (USDA) National Health and Nutrition Examination Survey, 
What We Eat in America, (NHANES/WWEIA). As to residue levels in food, 
EPA assumed 100 percent crop treated (PCT) at tolerance-level residues 
adjusted upward to account for metabolites which are not in the

[[Page 34631]]

tolerance expression from specific use patterns.
    ii. Chronic exposure. In conducting the chronic dietary exposure 
assessment EPA used the food consumption data from the USDA/NHANES/
WWEIA. As to residue levels in food, EPA made the same assumptions 
(adjusted tolerance-level residues and 100 PCT) as in the acute dietary 
exposure assessment.
    iii. Cancer. EPA determines whether quantitative cancer exposure 
and risk assessments are appropriate for a food-use pesticide based on 
the weight of the evidence from cancer studies and other relevant data. 
Cancer risk is quantified using a linear or nonlinear approach. If 
sufficient information on the carcinogenic mode of action is available, 
a threshold or nonlinear approach is used and a cancer RfD is 
calculated based on an earlier noncancer key event. If carcinogenic 
mode of action data are not available, or if the mode of action data 
determines a mutagenic mode of action, a default linear cancer slope 
factor approach is utilized. EPA has concluded that a nonlinear RfD 
approach is appropriate for assessing cancer risk to pyroxasulfone. 
Cancer risk was assessed using the same exposure estimates as discussed 
in Unit III.C.1.ii.
    iv. Anticipated residue and percent crop treated (PCT) information. 
EPA did not use anticipated residue and/or PCT information in the 
dietary assessment for pyroxasulfone. Adjusted 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 pyroxasulfone in drinking water. These simulation models 
take into account data on the physical, chemical, and fate/transport 
characteristics of pyroxasulfone. 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 
pyroxasulfone for acute exposures are estimated to be 17 parts per 
billion (ppb) for surface water and 210 ppb for ground water. EDWCs of 
pyroxasulfone for chronic exposures for non-cancer assessments are 
estimated to be 3.2 ppb for surface water and 174 ppb for ground water.
    Modeled estimates of drinking water concentrations were directly 
entered into the dietary exposure model. For acute dietary risk 
assessment, the water concentration value of 210 ppb was used to assess 
the contribution to drinking water. For chronic dietary risk 
assessment, the water concentration of value 174 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). Pyroxasulfone 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 
pyroxasulfone to share a common mechanism of toxicity with any other 
substances, and pyroxasulfone does not appear to produce a toxic 
metabolite produced by other substances. For the purposes of this 
tolerance action, therefore, EPA has assumed that pyroxasulfone 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 Food Quality 
Protection Act (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. The prenatal and postnatal 
toxicity database for pyroxasulfone includes developmental toxicity 
studies in rats and rabbits, a DNT study in rats, and a 2-generation 
reproduction toxicity study in rats. As discussed in the 2013 
rulemaking, evidence of increased susceptibility of fetuses and 
offspring was seen in the DNT study and developmental toxicity study in 
rabbits following in utero or post-natal exposure to pyroxasulfone. No 
increased susceptibility was seen in the rat developmental or 
reproduction toxicity studies. In rabbits, developmental toxicity was 
only seen at the limit dose of 1,000 milligrams/kilogram/day (mg/kg/
day) as reduced fetal weight and increased fetal resorptions with a 
NOAEL of 500 mg/kg/day for these effects, compared to no maternal 
toxicity at these doses. In a DNT study in rats, offspring toxicity 
(decreased brain weight and morphometric changes on PND 21) was seen at 
300 mg/kg/day compared to no maternal toxicity at 900 mg/kg/day. The 
degree of concern for the increased susceptibility seen in these 
studies is low and there are no residual uncertainties based on the 
following considerations:
    i. The increased susceptibility is occurring at high doses.
    ii. NOAELs and LOAELs have been identified for all effects of 
concern, and thus a clear dose response has been well defined.
    iii. The PODs selected for risk assessment are protective of the 
fetal/offspring effects.
    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 pyroxasulfone is complete.
    ii. Pyroxasulfone is a neurotoxic chemical and there is evidence of 
increased susceptibility of offspring with regard to neurotoxic effects 
in the rat DNT study. There is also evidence of increased 
susceptibility of fetuses/offspring with regard to non-neurotoxic 
effects in the rabbit developmental toxicity study. However, concern 
for the increased susceptibility is low for the reasons stated in Unit 
III.D.2.; therefore, EPA determined that a 10X FQPA SF is not necessary 
to protect infants and children.
    iii. There are no residual uncertainties identified in the exposure 
databases. The dietary food exposure assessments were performed based 
on 100 PCT and adjusted tolerance-level residues. EPA made conservative 
(protective) assumptions in the ground and surface

[[Page 34632]]

water modeling used to assess exposure to pyroxasulfone in drinking 
water. These assessments will not underestimate the exposure and risks 
posed by pyroxasulfone.

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. Using the exposure assumptions discussed in this 
unit for acute exposure, the acute dietary exposure from food and water 
to pyroxasulfone will occupy 3.6% of the aPAD for all infants (<1 year 
old), the population group receiving the greatest exposure.
    2. Chronic risk. Using the exposure assumptions described in this 
unit for chronic exposure, EPA has concluded that chronic exposure to 
pyroxasulfone from food and water will utilize 48% of the cPAD for all 
infants (<1 year old) the population group receiving the greatest 
exposure. There are no residential uses for pyroxasulfone.
    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). Short- and 
intermediate-term adverse effects were identified; however, 
pyroxasulfone is not registered for any use patterns that would result 
in short- or intermediate-term residential exposure. Because there is 
no short- or intermediate-term residential exposure and chronic dietary 
exposure has already been assessed under the appropriately protective 
cPAD (which is at least as protective as the POD used to assess short- 
and intermediate-term risk), no further assessment of short- or 
intermediate-term risk is necessary, and EPA relies on the chronic 
dietary risk assessment for evaluating short- and intermediate-term 
risk for pyroxasulfone.
    4. Aggregate cancer risk for U.S. population. The Agency has 
determined that the quantification of risk using a non-linear (i.e., 
RfD) approach will adequately account for all chronic toxicity, 
including carcinogenicity, that could result from exposure to 
pyroxasulfone. Therefore, based on the results of the chronic risk 
assessment discussed in Unit III.E.2., pyroxasulfone 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 pyroxasulfone residues.

IV. Other Considerations

A. Analytical Enforcement Methodology

    Adequate enforcement methodology (a liquid chromatography/mass 
spectrometry/mass spectrometry (LC/MS/MS) method) 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].

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 a MRL for pyroxasulfone.

V. Conclusion

    Therefore, tolerances are established for residues of 
pyroxasulfone, [3-[[[5-(difluoromethoxy)-1-methyl-3-(trifluoromethyl)-
1H-pyrazol-4-yl]methyl]sulfonyl]-4,5-dihydro-5,5-dimethylisoxazole], 
including its metabolites and degradates, as set forth in the 
regulatory text.

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 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

[[Page 34633]]

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).
