Background and Statutory Findings EPA, on its own initiative, in accordance with FFDCA sections 408(e) and 408(l)(6) of, 21 U.S.C. 346a(e) and 346a(1)(6), is establishing time-limited tolerances for residues of tolfenpyrad (4-chloro-3-ethyl-1-methyl-
                    *N-*
                    [4-(
                    *p*
                    -tolyloxy)benzyl]pyrazole-5-carboxamide), including its metabolites and degradates, in or on dry bulb onion at 0.09 parts per million (ppm), and watermelon at 0.7 ppm. These time-limited tolerances expire on December 31, 2020. Section 408(l)(6) of FFDCA requires EPA to establish a time-limited tolerance or exemption from the requirement for a tolerance for pesticide chemical residues in food that will result from the use of a pesticide under an emergency exemption granted by EPA under FIFRA section 18. Such tolerances can be established without providing notice or period for public comment. EPA does not intend for its actions on FIFRA section 18 related time-limited tolerances to set binding precedents for the application of FFDCA section 408 and the safety standard to other tolerances and exemptions. Section 408(e) of FFDCA allows EPA to establish a tolerance or an exemption from the requirement of a tolerance on its own initiative, 
                    *i.e.,*
                     without having received any petition from an outside party. 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. . . .” Section 18 of FIFRA authorizes EPA to exempt any Federal or State agency from any provision of FIFRA, if EPA determines that “emergency conditions exist which require such exemption.” EPA has established regulations governing such emergency exemptions in 40 CFR part 166. III. Emergency Exemptions for Tolfenpyrad on Dry Bulb Onion and Watermelon, and FFDCA Tolerances The Texas Department of Agriculture (TDA) stated that an emergency situation required the use of tolfenpyrad on dry bulb onions (
                    *Allium cepa*) to control onion thrips (
                    *Thrips tabaci*
                     Lindeman) in the Texas counties of Cameron, Dimmitt, Frio, Hidalgo, Maverick, Starr, Uvalde, Willacy and Zavala. According to TDA, this year's exceptionally mild winter and record high heat caused the development of large populations of onion thrips, a principle pest of onions, early in the onion crop cycle. The threshold level for applying pesticides to control thrips in onions is 5 to 25 thrips per plant, and TDA stated that over 100 thrips per plant were observed in Texas' dry bulb onion fields in early March, 2017. TDA stated that multiple applications of registered pesticides were not controlling these extreme population levels which can reduce yields and bulb size by as much as 50%. In addition, the transmission of iris yellow spot virus in onions, exclusively vectored by onion thrips, is a concern, and several onion fields have been observed with positive symptoms. TDA stated that this virus severely affects the shipping quality of onions, and can be more devastating than damage from the thrips themselves. Upon EPA concurrence, TDA allowed the use of tolfenpyrad under the provisions of a crisis exemption beginning on March 17, 2017, and 
                    ( print page 46931)
                    subsequently requested a specific exemption to allow the use of tolfenpyrad in dry bulb onions to continue beyond the 15 days provided by a crisis exemption alone. Separately, the Hawaii Department of Agriculture (HDA) stated that an emergency developed due to outbreaks of melon thrips in watermelon fields at unusually high levels, (up to 200 thrips per leaf), which registered pesticides were not controlling. HDA stated that above-average rainfall caused rapid growth of host plants, leading to development of very high levels of melon thrips in areas near watermelon fields. Subsequently, a 6-week drought caused early dry-down of this rainy-season vegetation, prompting massive migrations of melon thrips into neighboring watermelon fields. HDA stated that the melon thrips infestations have caused stunted vines, foliage discoloration, and in some instances have caused such severe damage that the plants no longer produce fruit. The melon aphid also transmits the tomato spotted wilt virus, which causes silver mottle disease in watermelon, further damaging the plants and causing additional yield losses. HDA stated that some watermelon acreage was abandoned due to the high level of damage from melon thrips infestations, and that significant yield and economic losses would occur in the remaining watermelon acreage without the requested use of tolfenpyrad. Upon EPA concurrence, HDA allowed the use of tolfenpyrad under the provisions of a crisis exemption, beginning on May 31, 2017, subsequently requesting a specific exemption to allow the use of tolfenpyrad in watermelon to continue beyond the 15 days provided under a crisis exemption alone. After having reviewed the submissions, EPA determined that emergency conditions exist for these States, and that the criteria for approval of the emergency exemptions had been met. Therefore, EPA authorized specific exemptions under FIFRA section 18 for the use of tolfenpyrad on dry bulb onion for control of onion thrips in Texas, and on watermelon for control of melon thrips in Hawaii. As part of its evaluation of the emergency exemption applications, EPA assessed the potential risks presented by residues of tolfenpyrad in or on dry bulb onion and watermelon. In doing so, EPA considered the safety standard in FFDCA section 408(b)(2), and decided that the necessary tolerances under FFDCA section 408(l)(6) would be consistent with the safety standard and with FIFRA section 18. Consistent with the need to move quickly on the emergency exemptions in order to address urgent, non-routine situations and to ensure that the resulting food is safe and lawful, EPA is issuing these tolerances without notice and opportunity for public comment as provided in FFDCA section 408(l)(6). Although these time-limited tolerances expire on December 31, 2020, under FFDCA section 408(l)(5), residues of the pesticide not in excess of the amounts specified in the tolerances remaining in or on dry bulb onion or watermelon after that date will not be unlawful, provided the pesticide was applied in a manner that was lawful under FIFRA, and the residues do not exceed a level that was authorized by these time-limited tolerances at the time of that application. EPA will take action to revoke these time-limited tolerances earlier if any experience with, scientific data on, or other relevant information on this pesticide indicate that the residues are not safe. Because these time-limited tolerances are being approved under emergency conditions, EPA has not made any decisions about whether tolfenpyrad meets FIFRA's registration requirements for use on dry bulb onion and watermelon or whether permanent tolerances for these uses would be appropriate. Under these circumstances, EPA does not believe that these time-limited tolerance decisions serve as bases for registration of tolfenpyrad by a State for special local needs under FIFRA section 24(c), nor do these tolerances by themselves serve as the authority for persons in any States other than Texas and Hawaii to use this pesticide on the applicable crops under FIFRA section 18, absent the issuance of an emergency exemption applicable within that State.

                    . IV. Aggregate Risk Assessment and Determination of Safety Consistent with 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 expected as a result of these emergency exemptions and the time-limited tolerances for residues of tolfenpyrad on dry bulb onion at 0.09 ppm, and watermelon at 0.7 ppm. EPA's assessment of exposures and risks associated with establishing the time-limited tolerances follows. A. 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 to humans by 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://www.epa.gov/​pesticide-science-and-assessing-pesticide-risks.* A summary of the toxicological profile and endpoints for tolfenpyrad used for human health risk assessment is discussed in Table 1 of the final rule published in the 
                    **Federal Register**
                     of January 9, 2014, (79 FR 1599) (FRL-9904-70). B. Exposure Assessment 1. 
                    *Dietary exposure from food and feed uses.*
                     In evaluating dietary exposure to tolfenpyrad, EPA considered exposures under the time-limited tolerances established by this action as well as all existing tolfenpyrad tolerances in 40 CFR 180.675. EPA assessed dietary exposures from tolfenpyrad in food as follows: i. 
                    *Acute exposure.*
                     Acute dietary exposure is quantified 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 tolfenpyrad. In estimating acute dietary exposure, EPA used food consumption information from the United States Department of Agriculture (USDA) 2003-2008 National Health and Nutrition Examination Survey/What We 
                    ( print page 46932)
                    Eat in America (NHANES/WWEIA). For the purposes of this acute exposure assessment, EPA assumed tolerance-level residues and 100 percent crop treated (PCT) for those crops on which tolfenpyrad use is registered and proposed. ii. 
                    *Chronic exposure.*
                     In conducting the chronic dietary exposure assessment EPA used the food consumption data from the USDA 2003-2008 NHANES/WWEIA. For the purposes of this chronic exposure assessment, EPA assumed 100 PCT and incorporated average residue levels from crop field trials for registered and proposed uses of tolfenpyrad. iii. 
                    *Cancer.*
                     No evidence of carcinogenicity was observed in cancer studies with mice and rats. For further detail on the results of these studies see “Tolfenpyrad. Human Health Risk Assessment” at 
                    *https://www.regulations.gov*
                     in docket ID number EPA-HQ-OPP-2012-0909. Therefore, in accordance with EPA's Final Guidelines for Carcinogen Risk Assessment (March 2005), tolfenpyrad is classified as “not likely to be carcinogenic to humans” and a cancer risk assessment is unnecessary. iv. 
                    *Anticipated residue and percent crop treated (PCT) information.*
                     Section 408(b)(2)(E) of FFDCA authorizes EPA to use available data and information on the anticipated residue levels of pesticide residues in food and the actual levels of pesticide residues that have been measured in food. If EPA relies on such information, EPA must require pursuant to FFDCA section 408(f)(1) that data be provided 5 years after the tolerance is established, modified, or left in effect, demonstrating that the levels in food are not above the levels anticipated. For the present action, EPA will issue such data call-ins as are required by FFDCA section 408(b)(2)(E) and authorized under FFDCA section 408(f)(1). Data will be required to be submitted no later than 5 years from the date of issuance of these tolerances. 2. 
                    *Dietary exposure from drinking water.*
                     The Agency used screening level water exposure models in the dietary exposure analysis and risk assessment for tolfenpyrad in drinking water. These simulation models take into account data on the physical, chemical, and fate/transport characteristics of tolfenpyrad. Further information regarding EPA drinking water models used in pesticide exposure assessment can be found at 
                    *https://www.epa.gov/​pesticide-science-and-assessing-pesticide-risks/​about-water-exposure-models-used-pesticide.* Based on the Pesticide Root Zone Model/Exposure Analysis Modeling System (PRZM/EXAMS) and Screening Concentration in Ground Water (SCI-GROW) models, the estimated drinking water concentrations (EDWCs) of tolfenpyrad are 26.9 ppb for acute exposure and 12.2 ppb for chronic exposure. These modeled estimates of drinking water concentrations were directly entered into the dietary exposure model. 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). Tolfenpyrad is not registered for any specific use patterns that would result in residential exposure. Further information regarding EPA standard assumptions and generic inputs for residential exposures may be found at: 
                    *https://www.epa.gov/​pesticide-science-and-assessing-pesticide-risks/​standard-operating-procedures-residential-pesticide.* 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 tolfenpyrad to share a common mechanism of toxicity with any other substances, and tolfenpyrad does not appear to produce a toxic metabolite produced by other substances. For the purposes of this tolerance action, therefore, EPA has assumed that tolfenpyrad 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/​pesticide-science-and-assessing-pesticide-risks/​cumulative-assessment-risk-pesticides.* C. 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 SF when reliable data available to EPA support the choice of a different factor. 2. 
                    *Prenatal and postnatal sensitivity.*
                     No evidence of increased quantitative or qualitative susceptibility was observed in developmental toxicity studies in rats or rabbits or a reproduction toxicity study in rats. However, the developmental immunotoxicity study (DIT) in rats suggests increased qualitative susceptibility in the young since toxicity observed in offspring animals was more pronounced than toxicity seen in maternal animals at the same dose. No evidence of quantitative susceptibility was seen in the study. There is low concern and there are no residual uncertainties regarding the increased qualitative prenatal and/or postnatal susceptibility observed for tolfenpyrad. When the DIT and the reproduction study are considered together, the offspring toxicity in the DIT is comparable in severity to maternal toxicity observed at the same dose in the reproduction study. Since the adverse effects in young occurred at exposure levels that have shown comparable effects in adults, EPA does not consider the DIT persuasive evidence of an increased susceptibility of infants or children to tolfenpyrad. Additionally, the effects observed in the DIT study are well-characterized, a clear NOAEL was identified, and the endpoints chosen for risk assessment are protective of potential offspring effects since a dermal hazard was not identified for tolfenpyrad, inhalation risk assessments are based on a route specific inhalation study, and the POD used for chronic dietary risk assessment is lower than where offspring effects were seen in the DIT study. 3. 
                    *Conclusion.*
                     EPA has determined that reliable data show that 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 tolfenpyrad is complete. ii. There is no indication that tolfenpyrad is a neurotoxic chemical and there is no need for a developmental neurotoxicity study or additional UFs to account for neurotoxicity. iii. Although there is possibly increased qualitative susceptibility in the young in the DIT study in rats, there are no residual uncertainties regarding increased susceptibility for tolfenpyrad since, (1) comparable maternal toxicity was observed at the same dose in the 
                    ( print page 46933)
                    reproduction study, (2) the offspring effects observed in the DIT study are well characterized and there is a clear NOAEL for the effects seen, (3) no evidence of quantitative susceptibility was seen in the DIT study and susceptibility was not observed (quantitative or qualitative) in rat or rabbit developmental toxicity or reproduction studies tested at similar doses, (4) the endpoints and PODs selected for risk assessment are protective, and (5) direct non-dietary exposure to children is not anticipated since there are no residential uses for tolfenpyrad. Thus, an additional FQPA safety factor is not necessary to protect infants and children. iv. There are no residual uncertainties identified in the exposure databases. EPA made conservative (protective) assumptions in the ground and surface water modeling used to assess exposure to tolfenpyrad in drinking water. Accordingly, these assessments will not underestimate the exposure and risks posed by tolfenpyrad. D. 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, drinking water and relevant residential exposure scenarios. Since there are no residential uses for tolfenpyrad, acute residential exposure is not anticipated and acute aggregate exposure results from dietary exposure to residues in food and drinking water alone. Therefore, acute aggregate risk estimates are equivalent to the acute dietary risk estimates. Using the exposure assumptions discussed in this unit for acute exposure, the acute dietary exposure from food and water to tolfenpyrad will occupy 56% of the aPAD for the general U.S. population. Children 3-5 years old are the highest-exposed population subgroup with an estimated acute dietary exposure of 80% of the aPAD. Typically, EPA has concerns when estimated exposures exceed 100% of the acute or chronic population-adjusted dose (aPAD or cPAD). Acute dietary risk estimates are below EPA's level of concern for all populations. 2. 
                    *Chronic risk.*
                     A chronic aggregate risk assessment takes into account chronic exposure estimates from dietary consumption of food and drinking water and relevant residential exposure scenarios. Since there are no residential uses for tolfenpyrad, chronic residential exposure is not anticipated and chronic aggregate exposure to tolfenpyrad results from dietary exposure to residues in food and drinking water alone. Therefore, chronic aggregate risk estimates for tolfenpyrad are equivalent to the chronic dietary risk estimates. Using the exposure assumptions described in this unit for chronic exposure, EPA has concluded that chronic exposure to tolfenpyrad from food and water will utilize 32% of the cPAD for the general U.S. population, and 81% of the cPAD for children 1-2 years old (the population group receiving the greatest exposure). 3. 
                    *Short-term risk.*
                     Short-term aggregate exposure takes into account short-term residential exposure plus chronic dietary exposure from food and water (considered to be a background (average) exposure level). A short-term adverse effect was identified; however, tolfenpyrad is not registered for any use patterns that would result in short-term residential exposure. Because there is no short-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-term risk), no further assessment of short-term risk is necessary, and EPA relies on the chronic dietary risk assessment for evaluating short-term risk for tolfenpyrad. 4. 
                    *Intermediate-term risk.*
                     Intermediate-term aggregate exposure takes into account intermediate-term residential exposure plus chronic dietary exposure from food and water (considered to be a background exposure level). An intermediate-term adverse effect was identified; however, tolfenpyrad is not registered for any use patterns that would result in intermediate-term residential exposure. Because there is no 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 intermediate-term risk), no further assessment of intermediate-term risk is necessary, and EPA relies on the chronic dietary risk assessment for evaluating intermediate-term risk for tolfenpyrad. 5. 
                    *Aggregate cancer risk for U.S. population.*
                     Based on the lack of evidence of carcinogenicity in two adequate rodent carcinogenicity studies, tolfenpyrad is not expected to pose a cancer risk to humans. 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, or to infants and children, from aggregate exposure to tolfenpyrad residues. V. Other Considerations A. Analytical Enforcement Methodology Adequate enforcement methodology (liquid chromatography/tandem mass spectrometry (LC/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 tolfenpyrad residues in dry bulb onion or watermelon. VI. Conclusion Therefore, time-limited tolerances are established for residues of tolfenpyrad (4-chloro-3-ethyl-1-methyl-

                    -tolyloxy)benzyl]pyrazole-5-carboxamide), including its metabolites and degradates, in or on onion, dry bulb at 0.09 ppm, and watermelon at 0.7 ppm. These tolerances expire on December 31, 2020.
                    ( print page 46934) VII. Statutory and Executive Order Reviews This action establishes tolerances under FFDCA sections 408(e) and 408(l)(6). 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) or Executive Order 13045, entitled “Protection of Children from Environmental Health Risks and Safety Risks” (62 FR 19885, April 23, 1997). 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 in accordance with FFDCA sections 408(e) and 408(l)(6), 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 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). VIII. 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). List of Subjects in 40 CFR Part 180 Environmental protection
