II. Summary of Petitioned-For Tolerance
In theFederal Registerof May 2, 2012 (77 FR 25954) (FRL-9346-1), 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 2E7991) by IR-4, 500 College Road East, Suite 201W, Princeton, NJ 08540. The petition requested that 40 CFR 180.155 be amended by establishing tolerances for residues of the plant growth regulator 1-naphthaleneacetic acid and its conjugates in or on rambutan at 3 parts per million (ppm); avocado, mango, and sapote, mamey at 0.05 ppm; and fruit, pome, group 11-10 at 0.15 ppm. The petition additionally requested to amend the tolerances in 40 CFR 180.155 by removing the tolerance for fruit, pome, group 11 at 0.15 ppm, as it will be superseded by the tolerance on fruit, pome, group 11-10 at 0.15 ppm. That document referenced a summary of the petition prepared on behalf of IR-4 by Amvac Chemical Corporation, the registrant, which is available in the docket, http://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 revised the proposed tolerance on rambutan from 3.0 ppm to 2.0 ppm. The Agency has also revised the tolerance expression for all established commodities to be consistent with current Agency policy. 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 that section, 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 1-naphthaleneacetic acid, including exposure resulting from the tolerances established by this action. EPA's assessment of exposures and risks associated with 1-naphthaleneacetic acid 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.
Based on structural activity relationship and metabolism data, all forms of 1-naphthaleneacetic acid, its salts, ester, and acetamide which are collectively referred to as naphthalene acetates (NAA), are expected to exhibit similar toxicological effects. In selecting endpoints of toxicity for risk assessment to exposures to the various NAA forms, the most conservative endpoint was selected from the studies that showed the lowest NOAELs for assessing a particular exposure. In addition, all forms degrade to the acid fairly quickly in the field and in biological systems.Therefore, EPA has concluded that required toxicity testing on any form should serve for all members of this group of chemicals.
Repeated oral exposures to NAA in rats and dogs resulted in decreased body weights, and body weight gains accompanied by decreased food consumption. The major target organs from subchronic and chronic oral exposures were the liver, stomach, and lung. Repeated oral exposures also resulted in decreased hematocrit and hemoglobin, along with reduced red blood cell count in rats and dogs and hypocellularity of the bone marrow in dogs.
There was no developmental toxicity at the highest dose of NAA (the acid) tested in the rat or in the rabbit (orally gavaged), but developmental toxicity (decreased fetal weight and minor skeletal changes) were seen in rats orally gavaged with the sodium salt. Reproductive effects of NAA sodium salts were limited to reduced litter survival and pup weight throughout lactation in both generations of offspring in a 2-generation reproduction study.
NAA and its acetamide and the ethyl ester were tested for mutagenic effects in a gene mutation bacterial assay, mouse lymphoma assay, and mouse erythrocyte micronucleus assay, mouse lymphoma assay, and mouse erythrocyte micronucleus assay and were not found to be mutagenic. Additionally, NAA was tested for mitotic gene conversion and dominant lethality in rats and found to be negative. In a published carcinogenicity study of NAA acetamide in mice and a guideline chronic/oncogenicity study of NAA sodium salt in rats and mice, NAA compounds were not carcinogenic in mice or rats.
Specific information on the studies received and the nature of the adverse effects caused by NAA 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 http://www.regulations.gov in document: “Naphthalene Acetates Human Health Risk Assessment for a Proposed Use on Avocado, Mango, Mamey Sapote, Rambutan, and Updating Crop Group Fruit, Pome, Group 11-10.” at pages 42-50 in docket ID number EPA-HQ-OPP-2012-0203.
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 (LOC) 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 (U/SF) are used in conjunction with the POD to calculate a safe exposure level—generally referred to as a population-adjusted dose (PAD) or a reference dose (RfD)—and a safe margin of exposure (MOE). For non-threshold risks, the Agency assumes that any amount of exposure will lead to some degree of risk. Thus, the Agency estimates risk in terms of the probability of an occurrence of the adverse effect expected in a lifetime. For more information on the general principles EPA uses in risk characterization and a complete description of the risk assessment process, see http://www.epa.gov/pesticides/factsheets/riskassess.htm.
A summary of the toxicological endpoints for NAA 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 NAA, EPA considered exposure under the petitioned-for tolerances as well as all existing NAA tolerances in 40 CFR 180.155. EPA assessed dietary exposures from NAA 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 NAA; 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) Version 3.16, which uses food consumption data from the U.S. Department of Agriculture's National Health and Nutrition Examination Survey, What We Eat in America, (NHANES/WWEIA), conducted from 2003-2008. As to residue levels in food, EPA assumed 100 percent crop treated (PCT) and tolerance-level residues for all commodities. In addition, DEEM version 7.81 default processing factors were used, when appropriate.
iii. Cancer. Based on the data summarized in Unit III.A., EPA has concluded that NAA 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 NAA. Tolerance level residues and/or 100 PCT were assumed for all food commodities.
2. Dietary exposure from drinking water. The Agency used screening level water exposure models in the dietary exposure analysis and risk assessment for NAA in drinking water. These simulation models take into account data on the physical, chemical, and fate/transport characteristics of NAA. Further information regarding EPA drinking water models used in pesticide exposure assessment can be found at http://www.epa.gov/oppefed1/models/water/index.htm.
Based on the First Index Reservoir Screening Tool (FIRST) and Concentration in Ground Water (SCI-GROW) models, the estimated drinking water concentrations (EDWCs) of NAA for chronic exposures for non-cancer assessments are estimated to be 2.99 parts per billion (ppb) for surface water and 0.0226 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 of value 3.0 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). NAA is currently registered for root dip and sprout inhibition applications to ornamentals, which could result in residential exposures. There is a potential for short-term dermal and inhalation exposures to residential handlers, resulting from loading and applying NAA. There are no residential uses for NAA that result in exposure to children via incidental oral activities. The rooting compounds are applied by holding the plant and dipping the roots into solution. Very little exposure is expected from this use. Sprout inhibitors are applied by spray or paint brush/roller after pruning trees, or by spraying near the base of the tree after pruning root suckers. There is very little potential for postapplication exposure to NAA for adults or children based on the residential use pattern; therefore, residential postapplication exposure is not expected, nor is intermediate- or long-term exposure scenarios based on the intermittent nature of applications by homeowners.
Further information regarding EPA standard assumptions and generic inputs for residential exposures may be found at http://www.epa.gov/pesticides/trac/science/trac6a05.pdf.
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 NAA to share a common mechanism of toxicity with any other substances, and NAA does not appear to produce a toxic metabolite produced by other substances. For the purposes of this tolerance action, therefore, EPA has assumed that NAA does not have a common mechanism of toxicity with other substances. For information regarding EPA's efforts to determine which chemicals have a common mechanism of toxicity and to evaluate the cumulative effects of such chemicals, see EPA's Web site at http://www.epa.gov/pesticides/cumulative.
D. Safety Factor for Infants and Children
1. In general. Section 408(b)(2)(C) of FFDCA provides that EPA shall apply an additional tenfold (10X) margin of safety for infants and children in the case of threshold effects to account for prenatal and postnatal toxicity and the completeness of the database on toxicity and exposure unless EPA determines based on reliable data that a different margin of safety will be safe for infants and children. This additional margin of safety is commonly referred to as the FQPA SF. In applying this provision, EPA either retains the default value of 10X, or uses a different additional safety factor when reliable data available to EPA support the choice of a different factor.
2. Prenatal and postnatal sensitivity. There is low concern and no residual uncertainty for pre- and/or postnatal toxicity resulting from exposure to the NAA group of chemicals. The available data provided no indication of increased quantitative or qualitative susceptibility of rats or rabbits to in utero exposure to NAA or to prenatal and postnatal exposure in rat reproduction studies. In the developmental toxicity study conducted with NAA sodium salt in rats, fetal toxicity (mainly decreased fetal weights and minor skeletal changes) was observed at a dose lower than the maternally toxic dose.
3. Conclusion. EPA has determined that reliable data show the safety of infants and children would be adequately protected if the FQPA SF was reduced to 1X for the oral and dermal routes of exposure and retained at 10X for the inhalation route of exposure. That decision is based on the following findings:
i. The toxicity database for NAA is not complete. EPA concluded that a 28-day inhalation toxicity study is required for NAA, based on a weight-of-evidence approach. A 10X SF was retained for the inhalation route of exposure due to the lack of the required 28-day inhalation study and given that the endpoint for subchronic inhalation is based on a developmental study (NOAEL = 50 mg/kg/day) that noted decreased body weight gains during gestation.
Additionally, recent changes to 40 CFR part 158 imposed new data requirements for immunotoxicity testing(OCSPP Guideline 870.7800) for pesticide registration. While an immunotoxicity study is not available for NAA, the toxicology database does not show any evidence of treatment-related effects on the immune system and the overall weight-of-evidence suggests that this chemical does not directly target the immune system. Consequently, the Agency does not believe that conducting a functional immunotoxicity study will result in a lower POD than that currently used for overall risk assessment, and therefore, an additional safety factor is not needed to account for lack of this study.
Acute and subchronic neurotoxicity studies are also required as a part of new data requirements in 40 CFR part 158; however, EPA has waived the requirement for these studies at the present time. This decision is based on: (1) The lack of neurotoxicity and neuropathology in the available toxicology studies for NAA; and (2) liver, stomach, and lung were identified as the target organs, with dogs being the most sensitive species. Therefore, neurotoxicity studies conducted in rats would not provide a more sensitive endpoint for risk assessment, and studies would be unlikely to yield PODs lower than the current PODs used for overall risk assessment.
ii. There is no indication that NAA 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 NAA results in increased susceptibility in in utero rats or rabbits in the prenatal developmental studies or in young rats in the 2-generation reproduction study. In the developmental toxicity study conducted with NAA sodium salt in rats, fetal toxicity was observed at a dose lower than the maternally toxic dose. However, there were clear NOAELs in this developmental study and the PODs used in the chronic dietary assessment (15 mg/kg/day) are protective of the fetal effects observed in the study.
iv. There are no residual uncertainties identified in the exposure databases. The chronic dietary food exposure assessment was performed based on 100 PCT and tolerance-level residues. EPA made conservative (protective) assumptions in the ground water and surface water modeling used to assess exposure to NAA in drinking water. Based on the discussion in Unit III.C.3., regarding limited residential use patterns, exposure to residential handlers is very low and EPA does not anticipate postapplication exposure to children or incidental exposures to toddlers resulting from use of NAA in residential settings. These assessments will not underestimate the exposure and risks posed by NAA.
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, NAA 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 NAA from food and water will utilize 2.0% 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 NAA 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). Though there is potential for short-term dermal and inhalation exposures to adult handlers resulting from residential applications of NAA to ornamentals, aggregate risk was not estimated for NAA because the toxicity endpoints selected for the chronic dietary route of exposure and those selected for inhalation and dermal routes of exposure are not based on common effects i.e., the chronic dietary endpoint is based on systemic effects and the dermal and inhalation endpoints are based on decreased body weight gain. Exposure pathways and routes are only aggregated when they share a common toxic effect.
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). Because no intermediate-term adverse effect was identified, NAA is not expected to pose an intermediate-term risk.
5. Aggregate cancer risk for U.S. population. Based on the lack of evidence of carcinogenicity in two adequate rodent carcinogenicity studies, NAA 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 NAA residues.
IV. Other Considerations
A. Analytical Enforcement Methodology
An adequate enforcement method, a high performance liquid chromatography (HPLC) method using fluorescence detection (Method NAA-AM-001) and a similar method (Method NAA-AM-002), is available to enforce the tolerance expression for NAA in plant commodities.
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@example.com.
B. International Residue Limits
In making its tolerance decisions, EPA seeks to harmonize U.S. tolerances with international standards whenever possible, consistent with U.S. food safety standards and agricultural practices. EPA considers the international maximum residue limits (MRLs) established by the Codex Alimentarius Commission (Codex), as required by FFDCA section 408(b)(4). The Codex Alimentarius is a joint United Nations Food and Agriculture Organization/World Health Organization food standards program, and it is recognized as an international food safety standards-setting organization in trade agreements to which the United States is a party. EPA may establish a tolerance that is different from a Codex MRL; however, FFDCA section 408(b)(4) requires that EPA explain the reasons for departing from the Codex level.
The Codex has not established a MRL for NAA.
C. Revisions to Petitioned-For Tolerances
Based on the data supporting the petition, EPA revised the proposed tolerance on rambutan from 3.0 ppm to2.0 ppm. The Agency revised this tolerance level based on analysis of the residue field trial data using the Organization for Economic Cooperation and Development (OECD) tolerance calculation procedures.
Finally, the Agency has revised the tolerance expression to clarify: (1) That, as provided in FFDCA section 408(a)(3), the tolerance covers metabolites and degradates of NAA not specifically mentioned; and (2) that compliance with the specified tolerance levels is to be determined by measuring only the specific compounds mentioned in the tolerance expression.
Therefore, tolerances are established for residues of NAA, 1-naphthaleneacetic acid, in or on avocado at 0.05 ppm; fruit, pome, group 11-10 at 0.15 ppm; sapote, mamey at 0.05 ppm; mango at 0.05 ppm; and rambutan at 2.0 ppm. This regulation additionally removes the tolerance in or on fruit, pome, group 11 at 0.15 ppm and the time-limited tolerance in or on avocado at 0.05 ppm.
VI. Statutory and Executive Order Reviews
This final rule establishes tolerances under FFDCA section 408(d) in response to a petition submitted to the Agency. The Office of Management and Budget (OMB) has exempted these types of actions from review under Executive Order 12866, entitled “Regulatory Planning and Review” (58 FR 51735, October 4, 1993). Because this final rule has been exempted from review under Executive Order 12866, this final rule is not subject to Executive Order 13211, entitled “Actions Concerning Regulations That Significantly Affect Energy Supply, Distribution, or Use” (66 FR 28355, May 22, 2001) or Executive Order 13045, entitled “Protection of Children from Environmental Health Risks and Safety Risks” (62 FR 19885, April 23, 1997). This final rule does not contain any information collections subject to OMB approval under the Paperwork Reduction Act (PRA) (44 U.S.C. 3501 et seq.), nor does it require any special considerations under Executive Order 12898, entitled “Federal Actions to Address Environmental Justice in Minority Populations and Low-Income Populations” (59 FR 7629, February 16, 1994).
Since tolerances and exemptions that are established on the basis of a petition under FFDCA section 408(d), such as the tolerance in this final rule, do not require the issuance of a proposed rule, the requirements of the Regulatory Flexibility Act (RFA) (5 U.S.C. 601 et seq.), do not apply.
This final rule directly regulates growers, food processors, food handlers, and food retailers, not States or tribes, nor does this action alter the relationships or distribution of power and responsibilities established by Congress in the preemption provisions of FFDCA section 408(n)(4). As such, the Agency has determined that this action will not have a substantial direct effect on States or tribal governments, on the relationship between the national government and the States or tribal governments, or on the distribution of power and responsibilities among the various levels of government or between the Federal Government and Indian tribes. Thus, the Agency has determined that Executive Order 13132, entitled “Federalism” (64 FR 43255, August 10, 1999) and Executive Order 13175, entitled “Consultation and Coordination with Indian Tribal Governments” (65 FR 67249, November 9, 2000) do not apply to this final rule. In addition, this final rule does not impose any enforceable duty or contain any unfunded mandate as described under Title II of the Unfunded Mandates Reform Act of 1995 (UMRA) (2 U.S.C. 1501 et seq.).
This action does not involve any technical standards that would require Agency consideration of voluntary consensus standards pursuant to section 12(d) of the National Technology Transfer and Advancement Act of 1995 (NTTAA) (15 U.S.C. 272 note).
VII. Congressional Review Act
Pursuant to the Congressional Review Act (5 U.S.C. 801 et seq.), EPA will submit a report containing this rule and other required information to the U.S. Senate, the U.S. House of Representatives, and the Comptroller General of the United States prior to publication of the rule in theFederal Register. This action is not a “major rule” as defined by 5 U.S.C. 804(2).
