Download as PDF 57336 Federal Register / Vol. 84, No. 207 / Friday, October 25, 2019 / Rules and Regulations Children from Environmental Health Risks and Safety Risks’’ (62 FR 19885, April 23, 1997), nor is it considered a regulatory action under 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 VerDate Sep<11>2014 17:20 Oct 24, 2019 Jkt 250001 Representatives, and the Comptroller General of the United States prior to publication of the rule in the Federal Register.

Summary of Petitioned-For Tolerance In the Federal Register of December 21, 2018 (83 FR 65660) (FRL–9985–67), EPA issued a document pursuant to FFDCA section 408(d)(3), 21 U.S.C. 346a(d)(3), announcing the filing of a VerDate Sep<11>2014 15:53 Oct 24, 2019 Jkt 250001 pesticide petition (PP 8E8694) by IR–4, IR–4 Project Headquarters, Rutgers, The State University of New Jersey, 500 College Road East, Suite 201 W, Princeton, NJ 08540. The petition requested that 40 CFR part 180 be amended by establishing tolerances for residues of the herbicide pendimethalin, including its metabolites and degradates, in or on the following raw agricultural commodities: Leaf petiole vegetables, subgroup 22B at 0.15 ppm; monarda, oil at 1.0 ppm; monarda, fresh leaves at 0.20 ppm; rosemary, oil at 1.0 ppm; and rosemary, fresh leaves at 0.20 ppm. That document referenced a summary of the petition prepared by BASF, the registrant, which is available in the docket, https:// www.regulations.gov. There were no comments received in response to the notice of filing. Based upon review of the data supporting the petition, EPA has modified the levels at which some of the tolerances are being set. The reason for these changes is 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 pendimethalin including exposure resulting from the tolerances established by this action. EPA’s assessment of exposures and risks associated with pendimethalin follows. PO 00000 Frm 00025 Fmt 4700 Sfmt 4700 57337 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 target organ for pendimethalin is the thyroid. Thyroid toxicity in chronic and subchronic rat and mouse studies was manifested as alterations in thyroid hormones (decreased total T4 and T3, increased percent of free T4 and T3), increased thyroid weight, and microscopic thyroid lesions (including increased thyroid follicular cell height, follicular cell hyperplasia, as well as follicular cell adenomas). Due to these effects, the Agency required that a developmental thyroid assay be conducted to evaluate the impact of pendimethalin on thyroid hormones, structure, and/or thyroid hormone homeostasis during development. A developmental thyroid study was submitted and demonstrated that there is no potential thyroid toxicity following pre- and/or post-natal exposure to pendimethalin. There is no evidence that pendimethalin is a developmental, reproductive, neurotoxic, or immunotoxic chemical. There is no evidence of increased qualitative or quantitative susceptibility in the young. EPA classified pendimethalin as a ‘‘Group C’’ possible human carcinogen based on a statistically significant increased trend and pair-wise comparison between the high-dose group and controls for thyroid follicular cell adenomas in male and female rats. A non-quantitative approach (i.e., nonlinear, reference dose (RfD) approach) was used to assess cancer risk since mode-of-action studies are available to demonstrate that the thyroid tumors are due to a thyroid-pituitary imbalance, and also since pendimethalin was shown to be non-mutagenic in mammalian somatic cells and germ cells. Specific information on the studies received and the nature of the adverse effects caused by pendimethalin as well as the no-observed-adverse-effect-level (NOAEL) and the lowest-observedadverse-effect-level (LOAEL) from the toxicity studies can be found at https:// www.regulations.gov in the document titled ‘‘Pendimethalin—Human Health Risk Assessment to Support the Proposed New Uses on Leaf Petiole Vegetable Subgroup 22B, Monarda and E:\FR\FM\25OCR1.SGM 25OCR1 57338 Federal Register / Vol. 84, No. 207 / Friday, October 25, 2019 / Rules and Regulations Rosemary’’ on pages 37–41 in docket ID number EPA–HQ–OPP–2018–0619. 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 https:// www2.epa.gov/pesticide-science-andassessing-pesticide-risks/assessinghuman-health-risk-pesticides. A summary of the toxicological endpoints for pendimethalin used for human risk assessment is discussed in Unit III.B of the final rule published in the Federal Register of February 16, 2018 (83 FR 6975) (FRL–9973–03). C. Exposure Assessment 1. Dietary exposure from food and feed uses. In evaluating dietary exposure to pendimethalin, EPA considered exposure under the petitioned-for tolerances as well as all existing pendimethalin tolerances in 40 CFR 180.361. EPA assessed dietary exposures from pendimethalin 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 pendimethalin. In estimating acute dietary exposure, EPA used Dietary Exposure Evaluation Model software VerDate Sep<11>2014 15:53 Oct 24, 2019 Jkt 250001 with the Food Commodity Intake Database (DEEM–FCID) Version 3.16. This software uses 2003–2008 food consumption data from the U.S. Department of Agriculture’s (USDA’s) National Health and Nutrition Examination Survey, What We Eat in America, (NHANES/WWEIA). As to residue levels in food, EPA used tolerance-level residues and 100 percent crop treated (PCT) for all commodities. ii. Chronic exposure. In conducting the chronic dietary exposure assessment EPA used the DEEM–FCID, Version 3.16 software with 2003–2008 food consumption data from the USDA’s NHANES/WWEIA. As to residue levels in food, EPA used tolerance-level residues and 100 PCT for all commodities. iii. Cancer. Based on the data summarized in Unit III.A., EPA has concluded that a nonlinear RfD approach is appropriate for assessing cancer risk to pendimethalin. Cancer risk was assessed using the same exposure estimates as discussed in Unit III.C.1.ii., chronic exposure. iv. Anticipated residue and PCT information. EPA did not use anticipated residue or PCT information in the dietary assessment for pendimethalin. Tolerance level residues and 100 PCT were assumed for all food commodities. 2. Dietary exposure from drinking water. In drinking water, the residue of concern is pendimethalin, parent only. The Agency used screening-level water exposure models in the dietary exposure analysis and risk assessment for pendimethalin in drinking water. These simulation models take into account data on the physical, chemical, and fate/ transport characteristics of pendimethalin. Further information regarding EPA drinking water models used in pesticide exposure assessment can be found at https://www2.epa.gov/ pesticide-science-and-assessingpesticide-risks/about-water-exposuremodels-used-pesticide. Based on the Pesticide Root Zone Model Ground Water (PRZM GW) and Surface Water Concentration Calculator (SWCC) models, the estimated drinking water concentrations (EDWCs) of pendimethalin for acute exposures are estimated to be 96.4 parts per billion (ppb) for surface water and 4.38 × 10 9 ppb for ground water. For chronic exposures they are estimated to be 9.73 ppb for surface water. For chronic exposures, pendimethalin did not reach groundwater even after running the model with an extended 100-year weather file. For the acute dietary risk assessment, the water concentration value of 96.4 PO 00000 Frm 00026 Fmt 4700 Sfmt 4700 ppb was used to assess the contribution to drinking water. For the chronic dietary risk assessment, the water concentration of value 9.73 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 nonoccupational, non-dietary exposure (e.g., for lawn and garden pest control, indoor pest control, termiticides, and flea and tick control on pets). Pendimethalin is currently registered for the following uses that could result in residential exposures: Turf, home gardens, and ornamentals. EPA assessed residential exposure using the following assumptions. First, for handlers, it is assumed that residential use will result in short-term (1 to 30 days) duration dermal and inhalation exposures. Second, residential post-application exposure is also assumed to be shortterm (1 to 30 days) in duration, resulting from the following exposure scenarios: (1) Gardening: Adults (dermal) and children 6 < 11 years old (dermal); (2) physical activities on turf: Adults (dermal) and children 1–2 years old (dermal and incidental oral); (3) mowing turf: Adults (dermal) and children 11 < 16 years old (dermal); and (4) exposure to golf courses during golfing: Adults (dermal), children 11 < 16 years old (dermal), and children 6 < 11 years old (dermal). EPA did not combine exposure resulting from adult handler and postapplication exposure resulting from treated gardens, lawns, and/or golfing because the conservative assumptions and inputs within each estimated exposure scenario would result in an overestimate of adult exposure. EPA selected the most conservative adult residential scenario (adult dermal postapplication exposure from gardening) as the contributing source of residential exposure to be combined with the dietary exposure for the aggregate assessment. The children’s oral exposure is based on post-application hand-to-mouth exposures. To include exposure from object-to-mouth and soil ingestion in addition to hand-to-mouth would overestimate the potential for oral exposure. However, there is the potential for co-occurrence of dermal and oral exposure, since the toxicological effects from the dermal and oral routes of exposure are the same. As a result, the children’s aggregate assessment combines postapplication dermal and oral exposure along with dietary exposure from food and water. Further information regarding EPA standard assumptions and generic inputs for residential E:\FR\FM\25OCR1.SGM 25OCR1 Federal Register / Vol. 84, No. 207 / Friday, October 25, 2019 / Rules and Regulations exposures may be found at https:// www2.epa.gov/pesticide-science-andassessing-pesticide-risks/standardoperating-procedures-residentialpesticide. 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 pendimethalin to share a common mechanism of toxicity with any other substances, and pendimethalin does not appear to produce a toxic metabolite produced by other substances. For the purposes of this tolerance action, therefore, EPA has assumed that pendimethalin 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:// www2.epa.gov/pesticide-science-andassessing-pesticide-risks/cumulativeassessment-risk-pesticides. 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 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 indication of pre- or postnatal qualitative or quantitative increased susceptibility in the developmental studies in rats and rabbits or the 2-generation reproduction studies in rats. A developmental thyroid toxicity study demonstrated that there is no potential thyroid toxicity following pre- and/or post-natal exposure to pendimethalin. 3. Conclusion. EPA has determined that reliable data show the safety of infants and children would be VerDate Sep<11>2014 15:53 Oct 24, 2019 Jkt 250001 adequately protected if the FQPA SF were reduced to 1X. That decision is based on the following findings: i. The toxicity database for pendimethalin is complete. Although a subchronic inhalation study was not available in the database, EPA determined that one is not needed at this time based on a weight-of-evidence analysis, considering the following: (1) All relevant hazard and exposure information, which indicates its low acute inhalation toxicity; (2) its physical/chemical properties, which indicate its low volatility; and (3) the use of an oral POD that results in a residential inhalation margin of exposure (MOE) more than 10X the level of concern (in the case of pendimethalin MOE = 30 based on thyroid POD). ii. There is no indication that pendimethalin is a neurotoxic chemical and there is no need for a developmental neurotoxicity study or additional UFs to account for neurotoxicity. iii. There is no evidence that pendimethalin results in increased susceptibility in utero rats or rabbits in the prenatal developmental studies or in young rats in the 2-generation reproduction study. In addition, a developmental thyroid toxicity study demonstrated that there is no potential thyroid toxicity following pre- or postnatal exposure to pendimethalin. iv. There are no residual uncertainties identified in the exposure databases. The dietary food exposure assessments were performed based on 100 PCT and tolerance-level residues. EPA made conservative (protective) assumptions in the ground and surface water modeling used to assess exposure to pendimethalin 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 pendimethalin. 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. PO 00000 Frm 00027 Fmt 4700 Sfmt 4700 57339 1. Acute risk. Using the exposure assumptions discussed in this unit for acute exposure, the acute dietary exposure from food and water to pendimethalin will occupy 2.1% 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 pendimethalin from food and water will utilize 2.4% of the cPAD for children one to two 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 pendimethalin 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). Pendimethalin is 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 pendimethalin. Using the exposure assumptions described in this unit for short-term exposures, EPA has concluded the combined short-term food, water, and residential exposures result in aggregate MOEs of 130 for adults and 92 for children 1 to 2 years old, the two population subgroups receiving the greatest combined dietary and nondietary exposure. Because EPA’s level of concern for pendimethalin is a MOE of 30 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, pendimethalin is not registered for any use patterns that would result in intermediate-term residential exposure. Intermediate-term risk is assessed based on intermediateterm 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 E:\FR\FM\25OCR1.SGM 25OCR1 57340 Federal Register / Vol. 84, No. 207 / Friday, October 25, 2019 / Rules and Regulations evaluating intermediate-term risk for pendimethalin. 5. Aggregate cancer risk for U.S. population. As discussed in Unit III.A., EPA has determined that an RfD approach based on the chronic point of departure is appropriate for evaluating cancer risk. As there are not chronic aggregate risks of concern, there are no cancer aggregate risk concerns. 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 pendimethalin residues. IV. Other Considerations A. Analytical Enforcement Methodology Adequate enforcement methodology, gas chromatography with electron capture detection (GC/ECD), 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 any MRLs for pendimethalin for the crops covered by this action. C. Revisions to Petitioned-For Tolerances The Agency is establishing tolerances for monarda, fresh leaves; rosemary, fresh leaves; monarda, oil; and rosemary, oil to be consistent with the Organization for Economic Co-operation and Development (OECD) rounding VerDate Sep<11>2014 15:53 Oct 24, 2019 Jkt 250001 class practice (at 0.2 ppm and 1 ppm instead of at 0.20 ppm and 1.0 ppm). For the joint review of the pendimethalin on celery data, the U.S. EPA and Canada PMRA have used the OECD calculation procedures to determine the recommended maximum residue level (MRL). Although the Agency-calculated level using the OECD procedure is the same as the petitionedfor level of 0.15 ppm, PMRA is proposing to recommend a MRL of 0.2 ppm for pendimethalin in celery. The different levels are a result of different proposed use rates in the U.S. and Canada. EPA is therefore establishing a U.S. tolerance of 0.2 ppm for the leaf petiole vegetable subgroup 22B for harmonization purposes with Canada. V. Conclusion Therefore, tolerances are established for residues of pendimethalin, including its metabolites and degradates, in or on the leaf petiole vegetable subgroup 22B at 0.2 ppm; monarda, fresh leaves at 0.2 ppm; monarda, oil at 1 ppm; rosemary, fresh leaves at 0.2 ppm; and rosemary, oil at 1 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) or Executive Order 13045, entitled ‘‘Protection of Children from Environmental Health Risks and Safety Risks’’ (62 FR 19885, April 23, 1997), nor is it considered a regulatory action under 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 PO 00000 Frm 00028 Fmt 4700 Sfmt 4700 under FFDCA section 408(d), such as the tolerances in this final rule, do not require the issuance of a proposed rule, the requirements of the Regulatory Flexibility Act (RFA) (5 U.S.C. 601 et seq.), do not apply. This 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).

II. Summary of Petitioned-For Tolerance

    In the Federal Register of December 21, 2018 (83 FR 65660) (FRL-
9985-67), 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 
8E8694) by IR-4, IR-4 Project Headquarters, Rutgers, The State 
University of New Jersey, 500 College Road East, Suite 201 W, 
Princeton, NJ 08540. The petition requested that 40 CFR part 180 be 
amended by establishing tolerances for residues of the herbicide 
pendimethalin, including its metabolites and degradates, in or on the 
following raw agricultural commodities: Leaf petiole vegetables, 
subgroup 22B at 0.15 ppm; monarda, oil at 1.0 ppm; monarda, fresh 
leaves at 0.20 ppm; rosemary, oil at 1.0 ppm; and rosemary, fresh 
leaves at 0.20 ppm. That document referenced a summary of the petition 
prepared by BASF, the registrant, which is available in the docket, 
https://www.regulations.gov. There were no comments received in response 
to the notice of filing.
    Based upon review of the data supporting the petition, EPA has 
modified the levels at which some of the tolerances are being set. The 
reason for these changes is 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 pendimethalin including 
exposure resulting from the tolerances established by this action. 
EPA's assessment of exposures and risks associated with pendimethalin 
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 target organ for pendimethalin is the thyroid. Thyroid toxicity 
in chronic and subchronic rat and mouse studies was manifested as 
alterations in thyroid hormones (decreased total T4 and T3, increased 
percent of free T4 and T3), increased thyroid weight, and microscopic 
thyroid lesions (including increased thyroid follicular cell height, 
follicular cell hyperplasia, as well as follicular cell adenomas). Due 
to these effects, the Agency required that a developmental thyroid 
assay be conducted to evaluate the impact of pendimethalin on thyroid 
hormones, structure, and/or thyroid hormone homeostasis during 
development. A developmental thyroid study was submitted and 
demonstrated that there is no potential thyroid toxicity following pre- 
and/or post-natal exposure to pendimethalin.
    There is no evidence that pendimethalin is a developmental, 
reproductive, neurotoxic, or immunotoxic chemical. There is no evidence 
of increased qualitative or quantitative susceptibility in the young. 
EPA classified pendimethalin as a ``Group C'' possible human carcinogen 
based on a statistically significant increased trend and pair-wise 
comparison between the high-dose group and controls for thyroid 
follicular cell adenomas in male and female rats. A non-quantitative 
approach (i.e., non-linear, reference dose (RfD) approach) was used to 
assess cancer risk since mode-of-action studies are available to 
demonstrate that the thyroid tumors are due to a thyroid-pituitary 
imbalance, and also since pendimethalin was shown to be non-mutagenic 
in mammalian somatic cells and germ cells.
    Specific information on the studies received and the nature of the 
adverse effects caused by pendimethalin as well as the no-observed-
adverse-effect-level (NOAEL) and the lowest-observed-adverse-effect-
level (LOAEL) from the toxicity studies can be found at https://www.regulations.gov in the document titled ``Pendimethalin--Human 
Health Risk Assessment to Support the Proposed New Uses on Leaf Petiole 
Vegetable Subgroup 22B, Monarda and

[[Page 57338]]

Rosemary'' on pages 37-41 in docket ID number EPA-HQ-OPP-2018-0619.

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 https://www2.epa.gov/pesticide-science-and-assessing-pesticide-risks/assessing-human-health-risk-pesticides.
    A summary of the toxicological endpoints for pendimethalin used for 
human risk assessment is discussed in Unit III.B of the final rule 
published in the Federal Register of February 16, 2018 (83 FR 6975) 
(FRL-9973-03).

C. Exposure Assessment

    1. Dietary exposure from food and feed uses. In evaluating dietary 
exposure to pendimethalin, EPA considered exposure under the 
petitioned-for tolerances as well as all existing pendimethalin 
tolerances in 40 CFR 180.361. EPA assessed dietary exposures from 
pendimethalin 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 pendimethalin. In estimating acute 
dietary exposure, EPA used Dietary Exposure Evaluation Model software 
with the Food Commodity Intake Database (DEEM-FCID) Version 3.16. This 
software uses 2003-2008 food consumption data from the U.S. Department 
of Agriculture's (USDA's) National Health and Nutrition Examination 
Survey, What We Eat in America, (NHANES/WWEIA). As to residue levels in 
food, EPA used tolerance-level residues and 100 percent crop treated 
(PCT) for all commodities.
    ii. Chronic exposure. In conducting the chronic dietary exposure 
assessment EPA used the DEEM-FCID, Version 3.16 software with 2003-2008 
food consumption data from the USDA's NHANES/WWEIA. As to residue 
levels in food, EPA used tolerance-level residues and 100 PCT for all 
commodities.
    iii. Cancer. Based on the data summarized in Unit III.A., EPA has 
concluded that a nonlinear RfD approach is appropriate for assessing 
cancer risk to pendimethalin. Cancer risk was assessed using the same 
exposure estimates as discussed in Unit III.C.1.ii., chronic exposure.
    iv. Anticipated residue and PCT information. EPA did not use 
anticipated residue or PCT information in the dietary assessment for 
pendimethalin. Tolerance level residues and 100 PCT were assumed for 
all food commodities.
    2. Dietary exposure from drinking water. In drinking water, the 
residue of concern is pendimethalin, parent only. The Agency used 
screening-level water exposure models in the dietary exposure analysis 
and risk assessment for pendimethalin in drinking water. These 
simulation models take into account data on the physical, chemical, and 
fate/transport characteristics of pendimethalin. Further information 
regarding EPA drinking water models used in pesticide exposure 
assessment can be found at https://www2.epa.gov/pesticide-science-and-assessing-pesticide-risks/about-water-exposure-models-used-pesticide.
    Based on the Pesticide Root Zone Model Ground Water (PRZM GW) and 
Surface Water Concentration Calculator (SWCC) models, the estimated 
drinking water concentrations (EDWCs) of pendimethalin for acute 
exposures are estimated to be 96.4 parts per billion (ppb) for surface 
water and 4.38 x 10\-9\ ppb for ground water. For chronic exposures 
they are estimated to be 9.73 ppb for surface water. For chronic 
exposures, pendimethalin did not reach groundwater even after running 
the model with an extended 100-year weather file.
    For the acute dietary risk assessment, the water concentration 
value of 96.4 ppb was used to assess the contribution to drinking 
water. For the chronic dietary risk assessment, the water concentration 
of value 9.73 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).
    Pendimethalin is currently registered for the following uses that 
could result in residential exposures: Turf, home gardens, and 
ornamentals. EPA assessed residential exposure using the following 
assumptions. First, for handlers, it is assumed that residential use 
will result in short-term (1 to 30 days) duration dermal and inhalation 
exposures. Second, residential post-application exposure is also 
assumed to be short-term (1 to 30 days) in duration, resulting from the 
following exposure scenarios: (1) Gardening: Adults (dermal) and 
children 6 < 11 years old (dermal); (2) physical activities on turf: 
Adults (dermal) and children 1-2 years old (dermal and incidental 
oral); (3) mowing turf: Adults (dermal) and children 11 < 16 years old 
(dermal); and (4) exposure to golf courses during golfing: Adults 
(dermal), children 11 < 16 years old (dermal), and children 6 < 11 
years old (dermal).
    EPA did not combine exposure resulting from adult handler and post-
application exposure resulting from treated gardens, lawns, and/or 
golfing because the conservative assumptions and inputs within each 
estimated exposure scenario would result in an overestimate of adult 
exposure. EPA selected the most conservative adult residential scenario 
(adult dermal post-application exposure from gardening) as the 
contributing source of residential exposure to be combined with the 
dietary exposure for the aggregate assessment. The children's oral 
exposure is based on post-application hand-to-mouth exposures. To 
include exposure from object-to-mouth and soil ingestion in addition to 
hand-to-mouth would overestimate the potential for oral exposure. 
However, there is the potential for co-occurrence of dermal and oral 
exposure, since the toxicological effects from the dermal and oral 
routes of exposure are the same. As a result, the children's aggregate 
assessment combines post-application dermal and oral exposure along 
with dietary exposure from food and water. Further information 
regarding EPA standard assumptions and generic inputs for residential

[[Page 57339]]

exposures may be found at https://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 pendimethalin to share a common mechanism of 
toxicity with any other substances, and pendimethalin does not appear 
to produce a toxic metabolite produced by other substances. For the 
purposes of this tolerance action, therefore, EPA has assumed that 
pendimethalin 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://www2.epa.gov/pesticide-science-and-assessing-pesticide-risks/cumulative-assessment-risk-pesticides.

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 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 indication of 
pre- or post-natal qualitative or quantitative increased susceptibility 
in the developmental studies in rats and rabbits or the 2-generation 
reproduction studies in rats. A developmental thyroid toxicity study 
demonstrated that there is no potential thyroid toxicity following pre- 
and/or post-natal exposure to pendimethalin.
    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 pendimethalin is complete. Although a 
subchronic inhalation study was not available in the database, EPA 
determined that one is not needed at this time based on a weight-of-
evidence analysis, considering the following: (1) All relevant hazard 
and exposure information, which indicates its low acute inhalation 
toxicity; (2) its physical/chemical properties, which indicate its low 
volatility; and (3) the use of an oral POD that results in a 
residential inhalation margin of exposure (MOE) more than 10X the level 
of concern (in the case of pendimethalin MOE = 30 based on thyroid 
POD).
    ii. There is no indication that pendimethalin is a neurotoxic 
chemical and there is no need for a developmental neurotoxicity study 
or additional UFs to account for neurotoxicity.
    iii. There is no evidence that pendimethalin results in increased 
susceptibility in utero rats or rabbits in the prenatal developmental 
studies or in young rats in the 2-generation reproduction study. In 
addition, a developmental thyroid toxicity study demonstrated that 
there is no potential thyroid toxicity following pre- or post-natal 
exposure to pendimethalin.
    iv. There are no residual uncertainties identified in the exposure 
databases. The dietary food exposure assessments were performed based 
on 100 PCT and tolerance-level residues. EPA made conservative 
(protective) assumptions in the ground and surface water modeling used 
to assess exposure to pendimethalin 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 
pendimethalin.

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 pendimethalin will occupy 2.1% 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 
pendimethalin from food and water will utilize 2.4% of the cPAD for 
children one to two 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 
pendimethalin 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). Pendimethalin 
is 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 pendimethalin.
    Using the exposure assumptions described in this unit for short-
term exposures, EPA has concluded the combined short-term food, water, 
and residential exposures result in aggregate MOEs of 130 for adults 
and 92 for children 1 to 2 years old, the two population subgroups 
receiving the greatest combined dietary and non-dietary exposure. 
Because EPA's level of concern for pendimethalin is a MOE of 30 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, 
pendimethalin is not registered for any use patterns that would result 
in intermediate-term residential exposure. Intermediate-term 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

[[Page 57340]]

evaluating intermediate-term risk for pendimethalin.
    5. Aggregate cancer risk for U.S. population. As discussed in Unit 
III.A., EPA has determined that an RfD approach based on the chronic 
point of departure is appropriate for evaluating cancer risk. As there 
are not chronic aggregate risks of concern, there are no cancer 
aggregate risk concerns.
    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 pendimethalin residues.

IV. Other Considerations

A. Analytical Enforcement Methodology

    Adequate enforcement methodology, gas chromatography with electron 
capture detection (GC/ECD), 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 any MRLs for pendimethalin for the 
crops covered by this action.

C. Revisions to Petitioned-For Tolerances

    The Agency is establishing tolerances for monarda, fresh leaves; 
rosemary, fresh leaves; monarda, oil; and rosemary, oil to be 
consistent with the Organization for Economic Co-operation and 
Development (OECD) rounding class practice (at 0.2 ppm and 1 ppm 
instead of at 0.20 ppm and 1.0 ppm). For the joint review of the 
pendimethalin on celery data, the U.S. EPA and Canada PMRA have used 
the OECD calculation procedures to determine the recommended maximum 
residue level (MRL). Although the Agency-calculated level using the 
OECD procedure is the same as the petitioned-for level of 0.15 ppm, 
PMRA is proposing to recommend a MRL of 0.2 ppm for pendimethalin in 
celery. The different levels are a result of different proposed use 
rates in the U.S. and Canada. EPA is therefore establishing a U.S. 
tolerance of 0.2 ppm for the leaf petiole vegetable subgroup 22B for 
harmonization purposes with Canada.

V. Conclusion

    Therefore, tolerances are established for residues of 
pendimethalin, including its metabolites and degradates, in or on the 
leaf petiole vegetable subgroup 22B at 0.2 ppm; monarda, fresh leaves 
at 0.2 ppm; monarda, oil at 1 ppm; rosemary, fresh leaves at 0.2 ppm; 
and rosemary, oil at 1 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) or Executive Order 13045, entitled 
``Protection of Children from Environmental Health Risks and Safety 
Risks'' (62 FR 19885, April 23, 1997), nor is it considered a 
regulatory action under 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 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).

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).
