II. Summary of Petitioned-For Tolerance
In the Federal Register of February 27, 2018 (83 FR 8408) (FRL-9972-17), 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 7F8624) by BASF Corporation, 26 Davis Drive, P.O. Box 13528, Research Triangle Park, NC 27709-3528. The petition requested that40 CFR 180.624be amended by establishing a tolerance for residues of the fungicide metrafenone, (3-bromo-6-methoxy-2-methylphenyl) (2,3,4-trimethoxy-6-methylphenyl)methanone, in or on mushroom at 0.5 parts per million (ppm). That document referenced a summary of the petition prepared by BASF Corporation, the registrant, which is available in the docket,http://www.regulations.gov. Comments were received on the notice of filing. EPA's response to these comments is discussed in Unit IV.C.
based upon review of the data supporting the petition, EPA is establishing the tolerance for residues of metrafenone at 0.50 ppm to be consistent with EPA rounding class practices. Additionally, the tolerance is established for the commodity White button mushroom to reflect the mushroom variety tested in the supporting crop field trial studies.
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 metrafenone including exposure resulting from the tolerances established by this action. EPA's assessment of exposures and risks associated with metrafenone 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 liver is the primary target organ for metrafenone in mice, rabbits and rats. Effects on the liver were seen in multiple studies throughout the database, including subchronic rat studies, the rabbit developmental toxicity study, and chronic studies in mice and rats. Liver effects observed in subchronic studies included increased liver weights, periportal cytoplasmic vacuolation, increased cholesterol, and hepatocellular hypertrophy. Liver effects observed in chronic studies included those from the subchronic studies as well as increased serum gamma glutamyl transferase, eosinophilic alterations, necrosis, polyploid hepatocytes, bile duct hyperplasia, liver masses, and hepatocellular adenomas. The additional effects in the chronic studies indicate a progression of toxicity with time. The effects on the liver are consistent with the results of the absorption, distribution, metabolism, and excretion (ADME) studies indicating that the highest tissue concentrations of metrafenone were found in the liver and gastrointestinal tract and that bile is the primary route of excretion.
Additionally, nephrotoxicity was observed following chronic exposure to metrafenone in mice and rats. The kidney effects observed in the chronic studies included subacute/chronic interstitial inflammation and chronic/progressive nephropathy, cysts, brown pigment in renal cells, increased urinary volume, and increased urinary protein.
In a 28-day dermal toxicity study in rats, there were no dermal or systemic effects observed up to the highest dose tested of 1,000 mg/kg/day, the limit dose. In a 28-day immunotoxicity study in female rats, no effect on the immune system was observed up to the highest dose tested of 1,000 mg/kg/day, the limit dose. This is consistent with the rest of the database where no effects on the immune system were observed in any study.
There was no evidence of qualitative or quantitative susceptibility in the developmental and reproduction toxicity studies. In the developmental rat study, no effects were observed in dams or fetuses up to the limit dose of 1,000 mg/kg/day. In the rabbit study, liver toxicity (increased liver weights, hypertrophy, and hepatocyte vacuolation) was observed in the dams but no developmental effects were observed up to the limit dose of 1,000 mg/kg/day.
In the rat reproduction toxicity study, there was no evidence of reproductive toxicity. Effects in the offspring (decreased pup weight) occurred at doses similar to those that cause toxicity in the parental animals (decreased body weight).
The required battery of mutagenicity studies was submitted, including bacterial reverse mutation assay, mammalian cell mutation (CHO cells), in vitro chromosome aberration (CHO cells), micronucleus assay and unscheduled DNA synthesis in mammalian cells in culture. There is no evidence that metrafenone is genotoxic.
In the mouse carcinogenicity study, liver tumors (increased incidence of hepatocellular adenomas and adenomas plus carcinomas) were observed in male Start Printed Page 12518mice at the highest dose of 1,109 mg/kg/day. In the rat chronic/carcinogenicity study, there was an increased incidence in hepatocellular adenomas in females at the high dose of 1,419 mg/kg/day. However, the tumors in the rat females were not considered in the weight-of-evidence finding because they were associated with excessive toxicity to the females, leading to a reduction of the dose during the study. The registrant submitted mechanistic studies to support a mode of action (MOA) for the liver tumors, but the studies were conducted in rats. Although the MOA was considered plausible, the Agency concluded the data on rats could not be used to support a MOA finding in mice. The Agency concluded that quantification of cancer risk using a non-linear approach would adequately account for all chronic toxicity (including carcinogenicity) that could result from exposure to metrafenone. The use of the chronic point of departure is protective based on the following reasons:
- A treatment-related increase in benign liver tumors was seen only in male CD-1 mice at doses that were adequate to assess the carcinogenicity.
- The liver tumors were observed at doses significantly higher (44x) than those currently used for risk assessment.
- No treatment-related tumors were seen in female mice.
- No treatment-related tumors were seen in male rats and liver tumors in female rats were seen only at the Limit Dose which was excessively toxic to females; no tumors were seen at the next dose of 5,000 ppm, which was considered adequate to assess carcinogenicity.
- There is no mutagenicity concern for metrafenone.
Specific information on the studies received and the nature of the adverse effects caused by metrafenone 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 athttp://www.regulations.govin document Metrafenone. Human Health Risk Assessment for the Section 3 Registration for Use on Mushrooms at pages 26-36 in docket ID number EPA-HQ-OPP-2017-0616.
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 levelgenerally 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, seehttps://www.epa.gov/?pesticide-science-and-assessing-pesticide-risks/?assessing-human-health-risk-pesticides.
A summary of the toxicological endpoints for metrafenone used for human risk assessment is discussed in Unit III.B. of the final rule published in the Federal Register of October 22, 2014 (79 FR 63047) (FRL-9917-56).
C. Exposure Assessment
1. Dietary exposure from food and feed uses. In evaluating dietary exposure to metrafenone, EPA considered exposure under the petitioned-for tolerance as well as all existing metrafenone tolerances in40 CFR 180.624. EPA assessed dietary exposures from metrafenone 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 metrafenone; therefore, a quantitative acute dietary exposure assessment is unnecessary.
ii. Chronic exposure. In conducting the chronic dietary exposure assessment EPA used the food consumption data from the USDA National Health and Nutrition Examination Survey, What We Eat in America, (NHANES/WWEIA; 2003-2008). As to residue levels in food, EPA assumed 100 percent crop treated (PCT), tolerance-level residues (using a 2X metabolism adjustment factor), and EPA's 2018 default processing factors (with the exception of chemical-specific processing factors where available).
iii. Cancer. based on the data summarized in Unit III.A., EPA has concluded that the use of the chronic point of departure is appropriate for assessing cancer risk to metrafenone. Therefore, a separate 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 metrafenone. Tolerance level residues (using a 2X metabolism adjustment factor), default processing factors (with the exception of chemical-specific processing factors where available), 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 metrafenone in drinking water. These simulation models take into account data on the physical, chemical, and fate/transport characteristics of metrafenone. Further information regarding EPA drinking water models used in pesticide exposure assessment can be found athttp://www2.epa.gov/?pesticide-science-and-assessing-pesticide-risks/?about-water-exposure-models-used-pesticide.
based on the Pesticide Root Zone Model/Exposure Analysis Modeling System (PRZM/EXAMS) and Pesticide Root Zone Model Ground Water (PRZM GW), the estimated drinking water concentrations (EDWCs) of metrafenone total toxic residues for chronic exposures are estimated to be 14.52 ppb for surface water and 12.3 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 14.52 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). Metrafenone is not registered for any specific use patterns that would result in residential exposure.
4. Cumulative effects from substances with a common mechanism of toxicity. Section 408(b)(2)(D)(v) of FFDCA requires that, when considering whether to establish, modify, or revoke a tolerance, the Agency consider Start Printed Page 12519available 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 metrafenone to share a common mechanism of toxicity with any other substances, and metrafenone does not appear to produce a toxic metabolite produced by other substances. For the purposes of this tolerance action, therefore, EPA has assumed that metrafenone 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 athttps://www.epa.gov/?pesticide-science-and-assessing-pesticide-risks/?guidance-identifying-pesticide-chemicals-and-other.
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 evidence of qualitative or quantitative susceptibility in the developmental and reproduction toxicity studies. In the developmental rat study, no effects were observed in dams or fetuses up to the limit dose of 1,000 mg/kg/day. In the rabbit study, liver toxicity (increased liver weights, hypertrophy, and hepatocyte vacuolation) was observed in the dams but no developmental effects were observed up to the limit dose of 1,000 mg/kg/day. In the rat reproduction toxicity study, there was no evidence of reproductive toxicity. Effects in the offspring (decreased pup weight) occurred at doses similar to those which cause toxicity in the parental animals (decreased body weight).
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 metrafenone is complete.
ii. There is no indication that metrafenone 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 metrafenone 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.
iv. There are no residual uncertainties identified in the exposure databases. The dietary food exposure assessments were performed based on 100 PCT, tolerance-level residues (using a 2X metabolism adjustment factor), and EPA's 2017 default processing factors (with the exception of chemical-specific processing factors where available). EPA made conservative (protective) assumptions in the ground and surface water modeling used to assess exposure to metrafenone in drinking water. These assessments will not underestimate the exposure and risks posed by metrafenone.
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, metrafenone 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 metrafenone from food and water will utilize 16% of the cPAD for children 1-2 years old, the population group receiving the greatest exposure. There are no residential uses for metrafenone.
3. Short- and intermediate-term risk. Short- and intermediate-term aggregate exposure takes into account short- and intermediate-term residential exposure plus chronic exposure to food and water (considered to be a background exposure level).
A short- and intermediate-term adverse effect was identified; however, metrafenone is not registered for any use patterns that would result in short- and/or intermediate-term residential exposure. Short- and intermediate-term risk is assessed based on short-term residential exposure plus chronic dietary exposure. Because there is no short- and/or 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 short-term risk), no further assessment of short-term risk is necessary, and EPA relies on the chronic dietary risk assessment for evaluating short- and intermediate-term risk for metrafenone.
4. Aggregate cancer risk for U.S. population. EPA considers the chronic aggregate risk assessment to be protective of any aggregate cancer risk.
5. Determination of safety. based on these risk assessments, EPA concludes that there is a reasonable certainty that no harm will result to the general population, or to infants and children from aggregate exposure to metrafenone residues.
IV. Other Considerations
A. Analytical Enforcement Methodology
Adequate enforcement methodology ((Method FAMS 105-01)) is available to enforce the tolerance expression. Additionally, BASF has proposed the QuEChERS LC-MS/MS method as a new enforcement method for metrafenone.
The method for Method FAMS 105-01 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 Start Printed Page 12520Organization/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 established an MRL for metrafenone in or on mushrooms at 0.5 ppm. The Codex MRL is for Mushrooms defined as VF 0450 to include button mushroom, Rodman's agaricus mushroom and Hime-Matsutake, edible fungi. This MRL matches the tolerance established for metrafenone in or on white button mushroom in the United States, with the exception of the number of significant digits.
C. Response to Comments
Two comments were received in response to the Notice of Filing associated with this action, requesting that the Agency deny approval of the product due to impacts on the environment. Because the Agency's role is to assess the safety of the tolerance, these comments are outside the scope of this rulemaking.
V. Conclusion
Therefore, tolerances are established for residues of metrafenone, (3-bromo-6-methoxy-2-methylphenyl) (2,3,4-trimethoxy-6-methylphenyl) methanone, in or on white button mushroom at 0.50 ppm.
VI. Statutory and Executive Order Reviews
This action establishes a tolerance 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 toExecutive Order 13211,entitled Actions Concerning Regulations That Significantly Affect Energy Supply, Distribution, or Use (66 FR 28355, May 22, 2001) orExecutive 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 underExecutive 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. 3501et seq.), nor does it require any special considerations underExecutive 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. 601et 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 thatExecutive Order 13132,entitled Federalism (64 FR 43255, August 10, 1999) andExecutive 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. 1501et 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. 272note).
VII. Congressional Review Act
Pursuant to the Congressional Review Act (5 U.S.C. 801et 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 by5 U.S.C. 804(2).
