II. Summary of Petitioned-For Tolerance

In the Federal Register of January 26, 2018 (83 FR 3659) (FRL-9971-46), 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 5F8521) by K-I Chemical USA, Inc., 11 Martine Ave., Suite 970, White Plains, NY 10606. The petition requested that 40 CFR part 180.659 be amended by establishing tolerances for residues of the herbicide pyroxasulfone, (3-[5-(difluoromethoxy)-1-methyl-3-(trifluoromethyl)pyrazol-4-yl methylsulfonyl]-4,5-dihydro-5,5-dimethyl-1,2-oxazole) in or on Crop Subgroup 1C, tuberous and corm vegetables (except granular/flakes and chips) at 0.05 parts per million (ppm); Crop Subgroup 3-07, bulb vegetables at 0.15 ppm; potatoes, granular/flakes at 0.3 ppm; and potato chips at 0.06 ppm. That document referenced a summary of the petition prepared by K-I Chemical USA, Inc., the registrant, which is available in the docket, http://www.regulations.gov. No comments were received in response to the notice of filing.

Because the January 26, 2018, document identified the K-I Chemical petition by the wrong petition number, EPA published another document in the Federal Register assigning the correct petition number to the K-I Chemical petition—PP6F8521. That document was published in the Federal Register on March 15, 2018 (83 FR 11448) (FRL-9974-72). No relevant comments were received on the notice of filing.

Based upon review of the data supporting the petition, EPA has modified the levels at which some of the tolerances are being established and also modified some of the crop definitions. 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 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

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.

The toxicology database for pyroxasulfone is adequate for evaluating and characterizing toxicity and selecting endpoints for purposes of this risk assessment. Pyroxasulfone acute toxicity to mammals is low by all routes of exposure. Subchronic and chronic oral studies in mice, rats and dogs produced a variety of effects including cardiac toxicity (increased cardiomyopathy), liver toxicity (centrilobular hepatocellular hypertrophy, histopathological and/or clinical pathological indicators), kidney toxicity (nephropathy), neurotoxicity (impaired hind limb function, ataxia, tremors, sciatic nerve lesions, axonal/myelin degeneration in the sciatic nerve and spinal cord sections), skeletal muscle myopathy, urinary bladder mucosal hyperplasia, and urinary bladder transitional cell papillomas. Minimal to mild cardiac myofiber degeneration and local inflammation were also seen in a rat dermal toxicity study. Neurotoxicity was also seen in a developmental neurotoxicity study in rats (decreased brain weight, decreased thickness of the hippocampus, corpus callosum and cerebellum in offspring). Dogs appear to be the most sensitive species to the neurotoxic effects of pyroxasulfone. Immunotoxicity studies in rats and mice show no evidence of immunotoxic effects from pyroxasulfone.

There is evidence of fetal and offspring susceptibility in the developmental neurotoxicity study in rats as effects occurred in the absence of maternal toxicity. There is no concern for reproductive toxicity. Pyroxasulfone is classified as “Not Likely to be Carcinogenic to Humans” at doses that do not cause crystals with subsequent calculi formation resulting in cellular damage of the urinary tract. The Agency has determined that the quantification of risk using a non-linear approach (i.e., reference dose (RfD)) will adequately account for all chronic toxicity, including carcinogenicity, that could result from exposure to pyroxasulfone.

Specific information on the studies received and the nature of the adverse effects caused by pyroxasulfone as the no-observed-adverse effect level (NOAEL) and lowest-observed adverse effect level (LOAEL) from the toxicity studies can be found at http://www.regulations.gov in document “Pyroxasulfone Human Health Risk Assessment for the Section 3 New Uses of Pyroxasulfone on Crop Subgroup 1C, tuberous and corm vegetables and Crop Group 3-07, bulb vegetables” at pages 39-53 in docket ID number EPA-HQ-OPP-2015-0787.

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 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 use https://www.epa.gov/​pesticide-science-and-assessing-pesticide-risks/​assessing-human-health-risk-pesticides.

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

C. Exposure Assessment

1. Dietary exposure from food and feed uses. In evaluating dietary exposure to pyroxasulfone, EPA 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 data from the United States Department of Agriculture (USDA) 2003-2008 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) and tolerance-level residues adjusted for metabolites which are not in the tolerance expression.

ii. Chronic exposure. In conducting the chronic dietary exposure assessment EPA used the food consumption data from the USDA 2003-2008 (NHANES/WWEIA). As to residue levels in food, EPA assumed 100 PCT and tolerance-level residues adjusted for metabolites which are not in the tolerance expression.

iii. Cancer. Based on the data summarized in Unit III.A., EPA has classified pyroxasulfone as “Not Likely to be Carcinogenic to Humans” at doses that do not cause crystals with subsequent calculi formation resulting in cellular damage of the urinary tract. The Agency has determined that the quantification of risk using a non-linear approach (i.e., RfD) will adequately account for all chronic toxicity, including carcinogenicity, that could result from exposure to pyroxasulfone.

iv. Anticipated residue and percent crop treated (PCT) information. EPA did not use anticipated residue and PCT information in the dietary assessment for pyroxasulfone. Tolerance-level residues and 100% crop treated (CT) 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 at https://www.epa.gov/​pesticide-science-and-assessing-pesticide-risks/​assessing-human-health-riskpesticides.

Based on the Pesticide Root Zone Model Ground Water (PRZM version 3.122)/Exposure Analysis Modeling System-Superseded (EXAMS version 2.98.04), the estimated concentrations of pyroxasulfone in surface water were minimal, and the highest estimated drinking water concentrations (EDWCs) of pyroxasulfone residues were from a Tier II PRZM-GW modeling at an application rate of 0.267 lbs active ingredient/Acre for registered crops. The same EDWCs have been used for the current human health dietary risk assessment. The EDWCs for peak concentration (used in the acute assessment) and 30-year average concentration (used in the chronic assessment) were 0.210 and 0.174 mg/L (ppm), respectively. Water residues were incorporated in the Dietary Exposure Evaluation Model—Food Commodity Intake Database (DEEM-FCID) into the food categories “water, direct, all sources” and “water, indirect, all sources.”

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 website at https://www.epa.gov/​pesticide-science-and-assessing-pesticide-risks/​assessing-human-health-riskpesticides.

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 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. Pyroxasulfone did not exhibit developmental toxicity in the rat guideline study at the limit dose of 1,000 mg/kg/day and it exhibited slight developmental toxicity in rabbits (reduced fetal weight and resorptions) at the limit dose of 1,000 mg/kg/day. However, developmental effects were noted in offspring at 300 mg/kg/day in the rat DNT study characterized as decreased brain weight and morphometric changes. Developmental effects in the rabbit developmental study and DNT study occurred in the absence of maternal toxicity, indicating potential increased quantitative susceptibility of offspring. In a rat reproductive toxicity study, reduced pup weight and body weight gains during lactation occurred at similar doses causing pronounced maternal toxicity (reduced body weight, body weight gain and food consumption and increased kidney weight, cardiomyopathy and urinary bladder mucosal hyperplasia with inflammation).

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. Available data indicates that pyroxasulfone produces neurotoxic effects in rats. The toxicity database includes specific acute and subchronic neurotoxicity tests, as well as a DNT study. Although the DNT indicated offspring are more sensitive to neurotoxic effects of pyroxasulfone, the dose-response is well characterized for neurotoxicity and a NOAEL is identified; therefore, there is no residual uncertainty with regard to neurotoxic effects for which a 10X must be retained.

iii. Evidence of increased susceptibility of fetuses and offspring was seen in a DNT study in rats and a developmental study in rabbits following in utero or post-natal exposure to pyroxasulfone. However, no susceptibility was seen in the rat developmental or reproduction studies. In rabbits, developmental toxicity was only seen at the limit dose of 1000 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 was seen at 300 mg/kg/day compared to no maternal toxicity at 900 mg/kg/day. This increased susceptibility is occurring at high doses. NOAELs and LOAELs have been identified for all effects of concern and thus, a clear dose response has been well defined. Therefore, residual uncertainties or concerns for pre- and/or post-natal toxicity are minimal, and EPA concludes that reducing the FQPA safety factor to 1X will be protective of such effects.

iv. There are no residual uncertainties identified in the exposure databases. The dietary food exposure assessments were performed based on 100% CT and tolerance-level residues. EPA made conservative (protective) assumptions in the ground and surface 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 population adjusted dose (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 3.7% of the aPAD for all infants less than 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 50% of the cPAD for all infants less than 1-year old, the population group receiving the greatest exposure.

3. Short-term and intermediate-term risk. Short-term and intermediate-term aggregate exposure takes into account short-term and intermediate-term residential exposure plus chronic exposure to food and water (considered to be a background exposure level).

Although short-term and intermediate-term adverse effects were identified, pyroxasulfone is not registered for any use patterns that would result in residential exposure. Therefore, EPA relies on the chronic dietary risk assessment for evaluating short-term and intermediate-term risk for pyroxasulfone.

4. Aggregate cancer risk for U.S. population. As explained in Unit III.A., 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 (high performance liquid chromatography/triple quadrupole mass spectrometry (LC/MS/MS) methods) are available to enforce the tolerance expression.

These methods may be requested from: Chief, Analytical Chemistry Branch, Environmental Science Center, 701 Mapes Rd., Ft. Meade, MD 20755-5350; telephone number: [phone]; email address: [e-mail].

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 in any of the proposed commodities.

C. Revisions to Petitioned-For Tolerances

The vegetable, tuberous and corm, subgroup 1C tolerance is being established at 0.08 ppm instead of 0.05 ppm. The petitioner's requested tolerance level included only residues from the parent and M1 metabolite. The Agency is establishing this tolerance at 0.08 ppm to account for the measurement of parent and four metabolites. Applying processing factors in accordance with the Agency's policy for determining such factors when measuring multiple pesticide residues, the Agency has determined that 0.20 ppm is an appropriate tolerance level for granules/flakes. In addition, The Agency has determined that a tolerance for potato chips is not required because residues will be within the tolerance level established for subgroup 1C.

V. Conclusion

Therefore, tolerances are established for residues of pyroxasulfone including its metabolites and degradates, in or on potatoes, granules/flakes at 0.20 ppm; vegetable, bulb, group 3-07 at 0.15 ppm; and vegetable, tuberous and corm, subgroup 1C at 0.08 ppm.

VI. Statutory and Executive Order Reviews

This action 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 action has been exempted from review under Executive Order 12866, this action 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); Executive Order 13045, entitled “Protection of Children from Environmental Health Risks and Safety Risks” (62 FR 19885, April 23, 1997); or Executive Order 13771, entitled “Reducing Regulations and Controlling Regulatory Costs” (82 FR 9339, February 3, 2017). This action 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 action 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 action. In addition, this action does not impose any enforceable duty or contain any unfunded mandate as described under Title II of the Unfunded Mandates Reform Act (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 (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).
