    II. Summary of Petitioned-For Tolerance

    In the Federal Register of June 8, 2017 (82 FR 26641) (FRL-9961-14), 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 6E8528) by IR-4 Project Headquarters, 500 College Road East, Suite 201W, Princeton, New Jersey 08540. The petition requested that 40 CFR part 180 be amended by establishing tolerances for residues of the herbicide, clopyralid, (3,6-dichloro-2-pyridinecarboxylic acid), in or on berry, low growing, subgroup 13-07G at 4.0 parts per million (ppm); berry, low growing, except strawberry, subgroup 13-07H at 4.0 ppm; brassica, leafy greens, subgroup 4-16B at 5.0 ppm; fruit, pome, group 11-10 at 0.05 ppm; fruit, stone, group 12-12 at 0.5 ppm; radish, roots at 0.3 ppm; stalk and stem vegetable subgroup 22A at 1.0 ppm; vegetable, brassica, head and stem, group 5-16 at 2.0 ppm; and vegetable, leaves of root and tuber, group 2 at 5.0 ppm. Additionally, upon establishment of the above new tolerances, the petitioner requests to amend 40 CFR 180.431 by removing the established tolerances for clopyralid in or on apple at 0.05 ppm, asparagus at 1.0 ppm, beet, garden, tops at 3.0 ppm, beet, sugar, tops at 3.0 ppm, brassica, head and stem, subgroup 5A at 2.0 ppm, brassica, leafy greens, subgroup 5B at 5.0 ppm, canola, seed at 3.0 ppm, cranberry at 4.0 ppm, fruit, stone, group 12 at 0.5 ppm, strawberry at 4.0 ppm, and turnip, greens at 4.0 ppm. That document referenced a summary of the petition prepared by Dow AgroSciences, the registrant, which is available in the docket, http://www.regulations.gov. One comment was received on the notice of filing. EPA's response to that comment is discussed in Unit IV.C.

    Consistent with the authority in FFDCA 408(d)(4)(A)(i), EPA is issuing tolerances that vary from what the petitioner sought. The reasons for these changes are explained in Unit IV.D.

    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 Start Printed Page 23821aggregate 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 clopyralid including exposure resulting from the tolerances established by this action. EPA's assessment of exposures and risks associated with clopyralid follows.

    A. Toxicological Profile

    EPA has evaluated the available toxicity data and considered their 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.

    Clopyralid has low acute toxicity via the dermal, oral, and inhalation routes of exposure. It is not a dermal irritant or sensitizer, but it is a severe eye irritant in its acid form.

    Toxicity was observed in the mouse after subchronic and chronic exposure and the rat and dog after chronic exposure, but consistent target organs were not identified. In dogs, reductions in red blood cell parameters, increased liver weight, and vacuolated adrenal cortical cells were observed, with skin lesions and clinical chemistry changes at the highest dose. In rats, stomach lesions were observed at the lowest-observed-adverse-effects level (LOAEL), and decreased body weight was observed at the high dose. In mice, the only observed effects were decreased body weight/body weight gain. No systemic toxicity was seen in a rabbit 21-day dermal toxicity study. The available toxicology studies did not indicate the potential for neurotoxicity, immunotoxicity or reproductive toxicity.

    The available database does not show evidence of increased qualitative or quantitative pre- and/or post-natal susceptibility in the available developmental or 2-generation reproduction toxicity studies. No developmental toxicity was observed in the rat at doses that caused maternal mortality. In the developmental study in the rabbit, decreased fetal body weight and hydrocephalus were observed, but only at a dose that caused significant maternal toxicity, including mortality, clinical signs of toxicity, and gastric mucosal lesions. Reproductive toxicity was not observed in the rat, but mean pup weights (day 28) were reduced, and relative pup liver weights were increased at doses that caused parental toxicity (decreased body weight/weight gain and food consumption; gastric lesions).

    There were no direct clinical or histopathological indications of neurotoxicity in the available studies at doses up to or exceeding the limit dose. Hydrocephalus was observed in the young in the rabbit developmental study, but only in the presence of significant maternal toxicity, including a high rate of mortality.

    Clopyralid is classified as “not likely to be carcinogenic to humans,” based on the lack of treatment-related tumors in the rat and mouse carcinogenicity studies, and negative results of the genotoxicity assays.

    Specific information on the studies received and the nature of the adverse effects caused by clopyralid as well as the no-observed-adverse-effect-level (NOAEL) and LOAEL from the toxicity studies can be found at http://www.regulations.gov in document SUBJECT: Clopyralid. Aggregate Human Health Risk Assessment to Support Proposed New Uses on Pome Fruit Group 11-10 and Radish Roots, Along with Various Crop Group/Subgroup Conversions and Expansions at pages 31-35 in docket ID number EPA-HQ-OPP-2017-0035.

    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://www2.epa.gov/​pesticide-science-and-assessing-pesticide-risks/​assessing-human-health-risk-pesticides.

    A summary of the toxicological endpoints for clopyralid 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 clopyralid, EPA considered exposure under the petitioned-for tolerances as well as all existing clopyralid tolerances in 40 CFR 180.431. EPA assessed dietary exposures from clopyralid 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 clopyralid; therefore, a quantitative acute dietary exposure assessment is unnecessary.

    ii. Chronic exposure. In conducting the chronic dietary exposure assessment, EPA used Dietary Exposure Evaluation Model software with the Food Commodity Intake Database (DEEM-FCID) which incorporates consumption data from the United States Department of Agriculture's (USDA) National Health and Nutrition Examination Survey, What We Eat in America, (NHANES/WWEIA) conducted from 2003 to 2008. As to residue levels in food, the chronic dietary exposure assessment was based on tolerance-level residues, and assumed that 100 percent (PCT) of all crops were treated.

    iii. Cancer. Based on the data summarized in Unit III.A., EPA has concluded that clopyralid 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 PCT information. EPA did not use anticipated residue and/or PCT information in the dietary assessment for clopyralid. Tolerance level residues and 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 clopyralid in drinking water. These simulation models take into account data on the physical, chemical, and fate/transport characteristics of clopyralid. Further information regarding EPA drinking water models used in pesticide exposure assessment can be found at http://www2.epa.gov/​pesticide-science-and-assessing-pesticide-risks/​about-water-exposure-models-used-pesticide.

    Based on the Pesticide Water Calculator Version 1.52 (PWC) model, the estimated drinking water concentrations (EDWCs) of clopyralid for chronic exposures for non-cancer assessments are estimated to be 5.43 parts per billion (ppb) for surface water and 38.1 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 value of 38.1 ppb was used to assess the contribution from 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).

    Clopyralid is currently registered for the following uses that could result in residential exposures: Weed control on lawns, turf and ornamentals in residential and public areas. EPA assessed residential exposure using the following assumptions: Residential handler exposures are not expected since the residential uses require that handlers wear specific clothing (e.g., long-sleeved shirt and long pants; shoes plus socks) and/or personal protective equipment (e.g., gloves). As a result, a residential handler assessment was not conducted. Short-term post-application exposure is anticipated for children from incidental oral contact with treated turf (hand-to-mouth, object-to-mouth and soil ingestion). Post-application dermal exposure is also anticipated from residential use of clopyralid. However, systemic toxicity via the dermal route of exposure is not expected for clopyralid. Therefore, dermal risks were not quantitatively assessed for residential exposure.

    Further information regarding EPA standard assumptions and generic inputs for residential exposures may be found at http://www2.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 clopyralid to share a common mechanism of toxicity with any other substances, and clopyralid does not appear to produce a toxic metabolite produced by other substances. For the purposes of this tolerance action, therefore, EPA has assumed that clopyralid does not have a common mechanism of toxicity with other substances.

    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 Start Printed Page 23823safety for infants and children in the case of threshold effects to account for prenatal and postnatal toxicity and the completeness of the database on toxicity and exposure unless EPA determines based on reliable data that a different margin of safety will be safe for infants and children. This additional margin of safety is commonly referred to as the FQPA Safety Factor (SF). In applying this provision, EPA either retains the default value of 10X, or uses a different additional safety factor when reliable data available to EPA support the choice of a different factor.

    2. Prenatal and postnatal sensitivity. There was no evidence of increased qualitative or quantitative sensitivity/susceptibility in the developing or young animal. In the rat developmental toxicity study, no developmental toxicity was observed at a maternally toxic dose. In the rat 2-generation reproductive toxicity study, decreased pup weight (post-natal day 28), and increased relative liver weights were observed at the parental LOAEL. Hydrocephalus and decreased mean fetal weight were observed in the rabbit developmental study, but at a dose that also caused significant maternal toxicity, including mortality; therefore, quantitative or qualitative developmental susceptibility was not observed for clopyralid.

    3. Conclusion. EPA has determined that reliable data show the safety of infants and children would be adequately protected if the Food Quality Protection Act Safety Factor Safety Factor (FQPA SF) were reduced to 1X. That decision is based on the following findings:

    i. The toxicity database for clopyralid is considered complete and no additional studies are required at this time.

    ii. There are no clinical or micropathological indications of neurotoxicity in the available subchronic and chronic studies in multiple species. Hydrocephalus was observed in fetuses in the rabbit developmental study, but only at a high dose that resulted in significant maternal toxicity, including mortality. There is no need for a developmental neurotoxicity study or additional uncertainty factors (UFs) to account for neurotoxicity.

    iii. There is no evidence that clopyralid results in increased susceptibility in utero in 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 dietary and residential exposure databases. EPA conducted the chronic dietary food exposure assessment based on 100 PCT, tolerance-level residues of clopyralid, and default processing factors, where applicable. EPA made conservative (protective) assumptions in the ground and surface water modeling used to assess exposure to clopyralid in drinking water. EPA used similarly conservative assumptions to assess post-application exposure of children as well as incidental oral exposure of toddlers. These assessments will not underestimate the exposure and risks posed by clopyralid.

    E. Aggregate Risks and Determination of Safety

    EPA determines whether acute and chronic dietary pesticide exposures are safe by comparing aggregate exposure estimates to the acute PAD (aPAD) and chronic PAD (cPAD). For linear cancer risks, EPA calculates the lifetime probability of acquiring cancer given the estimated aggregate exposure. Short-, intermediate-, and chronic-term risks are evaluated by comparing the estimated aggregate food, water, and residential exposure to the appropriate PODs to ensure that an adequate MOE exists.

    1. Acute risk. An acute aggregate risk assessment takes into account acute exposure estimates from dietary consumption of food and drinking water. No adverse effect resulting from a single oral exposure was identified and no acute dietary endpoint was selected. Therefore, clopyralid 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 clopyralid from food and water will utilize 26% of the cPAD for children 1-2 years old, the population group receiving the greatest exposure. Based on the explanation in Unit III.C.3., regarding residential use patterns, chronic residential exposure to residues of clopyralid is not expected.

    3. Short-term risk. Short-term aggregate exposure takes into account short-term residential exposure plus chronic exposure to food and water (considered to be a background exposure level). Several clopyralid products are currently registered for uses that could result in short-term residential exposure and the Agency has determined that it is appropriate to aggregate chronic exposure through food and water with short-term residential exposures to clopyralid.

    Using the exposure assumptions described in this unit for short-term exposures and data results from a most recent previous EPA assessment of residential exposure, the Agency combined food, water, and short-term residential exposures result in aggregate MOEs of 1600 for children. Because EPA's level of concern (LOC) for clopyralid is an MOE of 100 or below, these MOEs are not of concern.

    4. Intermediate-term risk. Intermediate-term aggregate exposure takes into account intermediate-term residential exposure plus chronic exposure to food and water (considered to be a background exposure level). An intermediate-term adverse effect was identified; however, clopyralid is not registered for any use patterns that would result in intermediate-term residential exposure. Intermediate-term risk aggregate risk is assessed based on intermediate- term residential exposure plus chronic dietary 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 clopyralid.

    5. Aggregate cancer risk for U.S. population. Based on the lack of evidence of carcinogenicity in two adequate rodent carcinogenicity studies, clopyralid 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 clopyralid residues.

    IV. Other Considerations

    A. Analytical Enforcement Methodology

    The Pesticide Analytical Manual Volume II (PAM II) lists a method utilizing gas chromatography with electron capture detection (GC/ECD) for determination of clopyralid residues in plant commodities (Method I or Method ACR 75.6).

    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 Start Printed Page 23824safety 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 clopyralid residues on any commodities for which tolerances are established in this rule.

    C. Response to Comments

    One comment to the Notice of Filing was received from an anonymous commenter that stated, in part, that no clopyralid (pesticide) residue should be allowed on food crops.

    EPA's Response: The Agency recognizes that some individuals believe that pesticides should not be allowed on agricultural crops. However, the existing legal framework provided by section 408 of the Federal Food, Drug and Cosmetic Act (FFDCA) states that tolerances may be set when persons seeking such tolerances or exemptions have demonstrated that the pesticide meets the safety standard imposed by that statute. This commenter's statements appear to be directed at the underlying statute and not EPA's implementation of it; the commenter has made no contention that EPA has acted in violation of the statutory framework.

    D. Revisions to Petitioned-For Tolerances

    EPA is establishing individual tolerances in kohlrabi and broccoli, chinese as they were part of subgroup 5A, but not included in expansion crop group 5-16 for which a tolerance is being established by this action.

    EPA is not establishing the petitioned-for tolerance for Berry, low growing, except strawberry, subgroup 13-07H because it is not necessary. All commodities in subgroup 13-07H, plus strawberry, are included in subgroup 13-07G.

    In accordance with its standard practice to provide greater precision about the levels of residues that are permitted by a tolerance, EPA is adding an additional significant figure to the petitioned-for tolerance values for the following commodities: Fruit, stone, group 12-12 from 0.5 to 0.50 ppm and radish, roots from 0.3 to 0.30. This is to avoid the situation where residues may be higher than the tolerance level, but as a result of rounding would be considered non-violative (for example, radish, roots proposed at 0.3 ppm was established at 0.30 ppm, to avoid an observed hypothetical tolerance at 0.34 ppm being rounded to 0.3 ppm).

    V. Conclusion

    Therefore, tolerances are established for residues of clopyralid, (3,6-dichloro-2-pyridinecarboxylic acid), in or on Berry, low growing, subgroup 13-07G at 4.0 ppm; Brassica, leafy greens, subgroup 4-16B at 5.0 ppm; broccoli, Chinese at 2.0 ppm; fruit, pome, group 11-10 at 0.05 ppm; fruit, stone, group 12-12 at 0.50 ppm; kohlrabi at 2.0 ppm; radish, roots at 0.30 ppm; stalk and stem vegetable subgroup 22A at 1.0 ppm; vegetable, Brassica, head and stem, group 5-16 at 2.0 ppm; and vegetable, leaves of root and tuber, group 2 at 5.0 ppm. In addition, established tolerances in or on “apple”; “asparagus”; “beet, garden, tops”; “beet, sugar, tops”; “Brassica, head and stem, subgroup 5A”; “Brassica, leafy greens, subgroup 5B”; “canola, seed”; “cranberry”; “fruit, stone, group 12”; “strawberry”; and “turnip, greens” are removed as they are superseded by this final tolerance rule.

    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).
