II. Background and Statutory Findings

In the Federal Register of February 14, 2003 (68 FR 7548) (FRL-7289-1), and March 5, 2003 (68 FR 10458) (FRL-7291-2), EPA issued notices pursuant to section 408(d)(3) of FFDCA, 21 U.S.C. 346a(d)(3), announcing the filing of pesticide petitions (PP 2F6480, 2F6439, and 9E6054) by Janssen Pharmaceutica Inc., Plant and Material Protection Division, 1125 Trenton-Harbouton Road, Titusville, NJ 08560, and Bayer Crop Science, 2 T.W. Alexander Drive, Research Triangle Park, NC 27709. These notices included a summary of the petitions prepared by Janseen Pharmaceutica Inc., and Bayer Crop Science, the registrants. There were no comments received in response to these notices of filing.

The petitions requested that 40 CFR 180.518 be amended by establishing tolerances for residues of the fungicide pyrimethanil, 4,6-dimethyl-N-phenyl-2-pyrimidinamine, in or on citrus fruits (calamondin, citrus citron, citrus hybrids, grapefruit, kumquat, lemon, lime, mandarin, sour and sweet oranges, pummelo and satsuma mandarin) at 6 parts per million (ppm); pome fruit (apples, pears, oriental pears, crabapples, loquats, mayhaws, and quince) wet pomace at 12 ppm; and pome fruit (apples, pears, oriental pears, crabapples, loquats, mayhaws, and quince) at 3 ppm 2F6480; tree nut, nutmeat, group at 0.25 ppm; tree nut, hulls, group at 12 ppm; fruit, pome, group at 0.20 ppm; apple, wet pomace at 0.75 ppm; fruit, stone, group at 3.0 ppm; grape at 3.0 ppm; grape, dry pomace at 20 ppm,; grape, wet pomace at 7.0 ppm; grape, raisen waste at 50 ppm; grape, raisin at 5.0 ppm; vegetable, bulb, group at 2.0 ppm; vegetable, tuberous and corm, subgroup at 0.05 ppm; strawberry at 3.0 ppm; tomato at 0.50 ppm; wheat, rotational at 0.05 ppm; cattle, meat at 0.1 ppm; cattle, meat-by-products at 0.1 ppm; and milk at 0.03 ppm 2F6439;, and banana at 0.10 ppm 9E6054.

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. * * *”

EPA performs a number of analyses to determine the risks from aggregate exposure to pesticide residues. For further discussion of the regulatory requirements of section 408 of FFDCA and a complete description of the risk assessment process, see the final rule on Bifenthrin Pesticide Tolerances November 26, 1997 (62 FR 62961) (FRL-5754-7).

III. Aggregate Risk Assessment and Determination of Safety

Consistent with section 408(b)(2)(D) of FFDCA, 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, consistent with section 408(b)(2) of FFDCA, for tolerances as follows: (1) For residues of pyrimethanil on almond at 0.20 ppm; almond, hulls at 12 ppm; apple, wet pomace at 12 ppm; banana at 0.10 ppm; citrus oil at 150 ppm; fruit, citrus, group 10 (post-harvest) at 10 ppm; fruit, pome, group 11 (pre-harvest and post-harvest) at 3.0 ppm; fruit, stone (except cherry), group 12 at 3.0 ppm; grape at 5.0 ppm; grape, raisin at 8.0 ppm; onion, dry bulb at 0.10 ppm; onion, green at 2.0 ppm; pistachio at 0.20 ppm; strawberry at 3.0 ppm; tomato at 0.50 ppm; and vegetable, tuberous and corm, subgroup 1C at 0.05 ppm; (2) for residues of pyrimethanil and its metabolite, 4-[4,6-dimethyl-2-pyrimidinyl)amino]phenol on cattle, fat at 0.01 ppm; cattle, kidney at 0.30 ppm; cattle, meat at 0.01 ppm; cattle, meat-by-products (except kidney) at 0.01 ppm; goat, fat at 0.01 ppm; goat, kidney at 0.30 ppm; goat, meat at 0.01 ppm; goat, meat-by-products (except kidney) at 0.01 ppm; horse, fat at 0.01 ppm; horse, kidney at 0.30 ppm; horse, meat at 0.01 ppm; horse, meat-by-products (except kidney) at 0.01 ppm; sheep, fat at 0.01 ppm; sheep, kidney at 0.30 ppm; sheep, meat at 0.01 ppm; and sheep, meat-by-products (except kidney) at 0.01 ppm; and (3) for residues of pyrimethanil and its metabolite, 4,[6-dimethyl-2-(phenyl]amino)-5-pyrimidinol in milk at 0.03 ppm. EPA's assessment of exposures and risks associated with establishing the tolerance 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 nature of the toxic effects caused by pyrimethanil are discussed in Table 1 of this unit as well as the no observed adverse effect level (NOAEL) and the lowest observed adverse effect level (LOAEL) from the toxicity studies reviewed.

B. Toxicological Endpoints

The dose at which the NOAEL from the toxicology study identified as appropriate for use in risk assessment is used to estimate the toxicological level of concern (LOC). However, the lowest dose at which LOAEL of concern is identified is sometimes used for risk assessment if no NOAEL was achieved in the toxicology study selected. An uncertainty factor (UF) is applied to reflect uncertainties inherent in the extrapolation from laboratory animal data to humans and in the variations in sensitivity among members of the human population as well as other unknowns. An UF of 100 is routinely used, 10X to account for interspecies differences and 10X for intraspecies differences.

Three other types of safety or UFs may be used: “Traditional UF” the “special FQPA safety factor; ” and the “ default FQPA safety factor.” By the term “traditional UF” EPA is referring to those additional UFs used prior to FQPA passage to account for data base deficiencies. These traditional UFs have been incorporated by the FQPA into the additional safety factor for the protection of infants and children. The term “special FQPA safety factor” refers to those safety factors that are deemed necessary for the protection of infants and children primarily as a result of the FQPA. The “default FQPA safety factor” is the additional 10X safety factor that is mandated by the statute unless it is decided that there are reliable data to choose a different additional factor (potentially a traditional UF or a special FQPA safety factor).

For dietary risk assessment (other than cancer) the Agency uses the UF to calculate an acute or chronic reference dose (aRfD or cRfD) where the RfD is equal to the NOAEL divided by an UF of 100 to account for interspecies and intraspecies differences and any traditional UFs deemed appropriate (RfD = NOAEL/UF). Where a special FQPA safety factor or the default FQPA safety factor is used, this additional factor is applied to the RfD by dividing the RfD by such additional factor. The acute or chronic Population Adjusted Dose (aPAD or cPAD) is a modification of the RfD to accommodate this type of safety factor.

For non-dietary risk assessments (other than cancer) the UF is used to determine the LOC. For example, when 100 is the appropriate UF (10X to account for interspecies differences and 10X for intraspecies differences) the LOC is 100. To estimate risk, a ratio of the NOAEL to exposures (margin of exposure (MOE) = NOAEL/exposure) is calculated and compared to the LOC.

The linear default risk methodology (Q*) is the primary method currently used by the Agency to quantify carcinogenic risk. The Q* approach assumes that any amount of exposure will lead to some degree of cancer risk. A Q* is calculated and used to estimate risk which represents a probability of occurrence of additional cancer cases (e.g., risk). An example of how such a probability risk is expressed would be to describe the risk as one in one hundred thousand (1 X 10-5), one in a million (1 X 10-6), or one in ten million (1 X 10-7). Under certain specific circumstances, MOE calculations will be used for the carcinogenic risk assessment. In this non-linear approach, a “point of departure” is identified below which carcinogenic effects are not expected. The point of departure is typically a NOAEL based on an endpoint related to cancer effects though it may be a different value derived from the dose response curve. To estimate risk, a ratio of the point of departure to exposure (MOEcancer = point of departure/exposures) is calculated.

A summary of the toxicological endpoints for pyrimethanil used for human risk assessment is shown in the following Table 2.

Cancer (oral, dermal, inhalation)Pyrimethanil was classified as a Group C carcinogen based on thyroid follicular cell tumors in both sexes of the 2-year rat study (NOAEL = 17 mg/kg/day). The Agency's Cancer Peer Review Committee recommended a threshold or Margin of Exposure (MOE) approach because the thyroid tumors associated with administration of pyrimethanil in Sprague-Dawley rats may be due to a disruption in the thyroid-pituitary status.

C. Exposure Assessment

1. Dietary exposure from food and feed uses. Tolerances have been established (40 CFR 180.518) for the residues of pyrimethanil, in or on imported wine grapes. Risk assessments were conducted by EPA to assess dietary exposures from pyrimethanil plus the metabolites, 4-[4,6-dimethyl-2-pyrimidinyl)amino]phenol and 4,6-dimethyl-2-(phenylamino)-5-pyrimidinol, in food as follows:

i. Acute exposure. Acute dietary 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.

In conducting the acute dietary risk assessment EPA used the Dietary Exposure Evaluation Model software with the Food Commodity Intake Database (DEEMTM-FCID), which incorporates food consumption data as reported by respondents in the United States Department of Agriculture (USDA) 1994-1996 and 1998 Nationwide Continuing Surveys of Food Intake by Individuals (CSFII), and accumulated exposure to the chemical for each commodity. The following assumptions were made for the acute exposure assessments: The acute analysis assumed tolerance level residues, 100% crop treated, and DEEMTM (ver. 7.76) default processing factors for all proposed commodities. Percent crop treated (PCT) data and anticipated residues were not used.

ii. Chronic exposure. In conducting the chronic dietary risk assessment EPA used the DEEM software with the FCID, which incorporates food consumption data as reported by respondents in the USDA 1994-1996 and 1998 Nationwide CSFII, and accumulated exposure to the chemical for each commodity. The following assumptions were made for the chronic exposure assessments: The chronic analyses assumed tolerance level residues for ruminant tissues and milk and was refined through the use of average crop field trial residues for all crops. Conservative projected PCT estimates were used.

iii. Cancer. In conducting the cancer dietary risk assessment, EPA used the Dietary Exposure Evaluation Model software with the Food Commodity Intake Database (DEEM-FCIDTM), which incorporates food consumption data as reported by respondents in the USDA 1994-1996 and 1998 Nationwide Continuing Surveys of Food Intake by Individuals (CSFII), and accumulated exposure to the chemical for each commodity. The cancer risk assessment used the MOE methodology (MOE equals NOAEL (17 mg/kg/day) divided by chronic exposure). The following assumptions were made for the cancer exposure assessment: The cancer analyses assumed tolerance level residues for ruminant tissues and milk and was refined through the use of average crop field trial residues for all crops. Conservative projected percent crop treated estimates were used.

iv. Anticipated residue and PCT information. Section 408(b)(2)(E) of FFDCA authorizes EPA to use available data and information on the anticipated residue levels of pesticide residues in food and the actual levels of pesticide chemicals that have been measured in food. If EPA relies on such information, EPA must require that data be provided 5 years after the tolerance is established, modified, or left in effect, demonstrating that the levels in food are not above the levels anticipated. Following the initial data submission, EPA is authorized to require similar data on a time frame it deems appropriate. As required by section 408(b)(2)(E) of FFDCA, EPA will issue a Data-Call-In for information relating to anticipated residues to be submitted no later than 5 years from the date of issuance of this tolerance.

Section 408(b)(2)(F) of FFDCA states that the Agency may use data on the actual percent of food treated for assessing chronic dietary risk only if the Agency can make the following findings: Condition 1, that the data used are reliable and provide a valid basis to show what percentage of the food derived from such crop is likely to Start Printed Page 52439contain such pesticide residue; Condition 2, that the exposure estimate does not underestimate exposure for any significant subpopulation group, and Condition 3, if data are available on pesticide use and food consumption in a particular area, the exposure estimate does not understate exposure for the population in such area. In addition, the Agency must provide for periodic evaluation of any estimates used. To provide for the periodic evaluation of the estimate of PCT as required by section 408(b)(2)(F) of FFDCA, EPA may require registrants to submit data on PCT.

The Agency used projected PCT (PPCT) information for the following crops: almonds, apples (field use), grapes, onions, pear (field use), peach/stone fruit, potatoes, strawberries, tomatoes, post harvest pome fruit, and post-havest citrus. A 100% crop treated estimate was assumed for bananas, tuberous and corm vegetables (excluding potatoes), milk, meat and meat-by-products. These PPCT values are based on projected market share information. The registrants provided the Agency with their anticipated market share projections. The Agency estimated market share projections by comparing the efficacy spectrum of the registered alternatives to the efficacy spectrum of pyrimethanil. In conducting its risk assessment, the Agency utilized EPA-derived estimates. As to Condition 1, the Agency believes that this approach is conservative and will overestimate the potential risk. To further ensure the reliability of these data, as a condition of registration, the registrant will be required to provide annual reports on the market penetration and market share of pyrimethanil for each of the registered crops. As to Conditions 2 and 3, regional consumption information and consumption information for significant subpopulations is taken into account through EPA's computer-based model for evaluating the exposure of significant subpopulations including several regional groups. Use of this consumption information in EPA's risk assessment process ensures that EPA's exposure estimate does not understate exposure for any significant subpopulation group and allows the Agency to be reasonably certain that no regional population is exposed to residue levels higher than those estimated by the Agency. Other than the data available through national food consumption surveys, EPA does not have available information on the regional consumption of food to which pyrimethanil may be applied in a particular area.

2. Dietary exposure from drinking water. The Agency lacks sufficient monitoring exposure data to complete a comprehensive dietary exposure analysis and risk assessment for pyrimethanil and its major metabolite, 2-amino-4,6-dimethylpyrimidine in drinking water. Because the Agency does not have comprehensive monitoring data, drinking water concentration estimates are made by reliance on simulation or modeling taking into account data on the physical characteristics of pyrimethanil and 2-amino-4,6-dimethylpyrimidine. Pyrimethanil is expected to have low mobility in the environment, and 2-amino-4,6,-dimethylpyrimidine is expected to be moderately mobile and more persistent in the environment.

The Agency uses the Generic Estimated Environmental Concentration (GENEEC) or the Pesticide Root Zone Model/Exposure Analysis Modeling System (PRZM/EXAMS) to estimate pesticide concentrations in surface water and SCI-GROW, which predicts pesticide concentrations in ground water. In general, EPA will use GENEEC (a Tier 1 model) before using PRZM/EXAMS (a Tier 2 model) for a screening-level assessment for surface water. The GENEEC model is a subset of the PRZM/EXAMS model that uses a specific high-end runoff scenario for pesticides. GENEEC incorporates a farm pond scenario, while PRZM/EXAMS incorporate an index reservoir environment in place of the previous pond scenario. The PRZM/EXAMS model includes a percent crop area factor as an adjustment to account for the maximum percent crop coverage within a watershed or drainage basin.

None of these models include consideration of the impact processing (mixing, dilution, or treatment) of raw water for distribution as drinking water would likely have on the removal of pesticides from the source water. The primary use of these models by the Agency at this stage is to provide a screen for sorting out pesticides for which it is unlikely that drinking water concentrations would exceed human health levels of concern.

Since the models used are considered to be screening tools in the risk assessment process, the Agency does not use estimated environmental concentrations (EECs), which are the model estimates of a pesticide's concentration in water. EECs derived from these models are used to quantify drinking water exposure and risk as a percent referance dose (%RfD) or percent population adjusted dose (%PAD). Instead drinking water levels of comparison (DWLOCs) are calculated and used as a point of comparison against the model estimates of a pesticide's concentration in water. DWLOCs are theoretical upper limits on a pesticide's concentration in drinking water in light of total aggregate exposure to a pesticide in food, and from residential uses. Since DWLOCs address total aggregate exposure to pyrimethanil and 2-amino-4,6-dimethylpyrimidine they are further discussed in the aggregate risk sections in Unit III.

Based on the PRZM/EXAMS and SCI-GROW models, the EECs of pyrimethanil and 2-amino-4,6-dimethylpyrimidine for acute exposures are estimated to be 37.8 parts per billion (ppb) for surface water and 4.8 ppb for ground water. The EECs for chronic exposures are estimated to be 5.1 ppb for surface water and 4.8 ppb for ground water. All EECs were adjusted for regional percent cropped area and all EECs were developed using the strawberry use pattern which represents the worst case scenario (highest single and seasonal application rates).

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).

Pyrimethanil is not registered for use on any sites 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 “available information” concerning the cumulative effects of a particular pesticide's residues and “other substances that have a common mechanism of toxicity.”

Unlike other pesticides for which EPA has followed a cumulative risk approach based on a common mechanism of toxicity, EPA has not made a common mechanism of toxicity finding as to pyrimethanil and any other substances and pyrimethanil does not appear to produce a toxic metabolite produced by other substances. For the purposes of this tolerance action, therefore, EPA has not assumed that pyrimethanil has 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 the policy statements released by EPA's OPP concerning Start Printed Page 52440common mechanism determinations and procedures for cumulating effects from substances found to have a common mechanism on EPA's web site at http://www.epa.gov/​pesticides/​cumulative/​.

Section 408 of FFDCA provides that EPA shall apply an additional tenfold margin of safety (MOS) for infants and children in the case of threshold effects to account for prenatal and postnatal toxicity and the completeness of the data base on toxicity and exposure unless EPA determines based on reliable data that a different MOS will be safe for infants and children. MOS are incorporated into EPA risk assessments either directly through use of a MOE analysis or through using UFs (safety) in calculating a dose level that poses no appreciable risk to humans. In applying this provision, EPA either retains the default value of 10X when reliable data do not support the choice of a different factor, or, if reliable data are available, EPA uses a different additional safety factor value based on the use of traditional UFs and/or special FQPA safety factors, as appropriate.

2. Prenatal and postnatal sensitivity. EPA determined that there are no residual concerns for pyrimethanil for prenatal and postnatal toxicologically based on the following:

  • There is no evidence of qualitative or quantitative increased susceptibility following prenatal or postnatal exposures.
  • There are no concerns or residual uncertainties for prenatal and/or postnatal toxicity following exposure to pyrimethanil.
  • Because a decrease in thyroid hormones may cause neurotoxicity in the young exposed prior to birth or early in life, the Agency considered the possible need for a comparative thyroid assay and reviewed the evidence for thyroid toxicity in the data base. The Agency concluded that a comparative thyroid assay in young and adult rats is not required.
  • Based on the weight-of-evidence presented, the Agency concluded that a developmental neurotoxicity study is not required for pyrimethanil since there is no evidence of neuropathology and no neurotoxic signs up to 400 mg/kg/day in a subchronic neurotoxicity study in rats; the only evidence of neurotoxicity occurs after an acute dose level (1,000 mg/kg) much higher than those used to establish endpoints for risk assessment (100 mg/kg for acute exposures; approximately 20 mg/kg/day for repeated exposures), the 1,000 mg/kg/day dose is also higher than the doses tested or than those used in the reproduction study, which had a high dose of 343 mg/kg/day.
  • The Agency noted, as seen in the CPRC report, that the effects on the thyroid-pituitary status were associated with the large increase in uridine diphosphate glucuronosyl transferases seen in the 14-day dietary rat study. The effects seen in the thyroid and the liver, while treatment-related, are not severe in nature; in each of these studies there is a wide dose spread (approxiamately 10-fold difference between NOAELs and LOAELs) which provides a measure of protection for any potential effects reflecting increased sensitivity or susceptibility in offspring. Additionally, the endpoints selected for risk assessment will cover any concern for thyroid or liver effects seen at higher doses.
  • The Agency has a complete database on rat thyroid tumors. The mode of action in thyroid tumors in rats is well understood.

3. Conclusion. There is a complete toxicity data base for pyrimethanil and exposure data are complete or are estimated based on data that reasonably accounts for potential exposures. The FQPA factor is removed because of the completeness of the data base and the lack of concern for prenatal and postnatal toxicity. EPA concluded that reliable data shows an additional safety factor of 10X is not needed for the protection of infants and children.

E. Aggregate Risks and Determination of Safety

To estimate total aggregate exposure to a pesticide from food, drinking water, and residential uses, the Agency calculates DWLOCs which are used as a point of comparison against EECs. DWLOC values are not regulatory standards for drinking water. DWLOCs are theoretical upper limits on a pesticide's concentration in drinking water in light of total aggregate exposure to a pesticide in food and residential uses. In calculating a DWLOC, the Agency determines how much of the acceptable exposure (i.e., the PAD) is available for exposure through drinking water e.g., allowable chronic water exposure (mg/kg/day) = cPAD - (average food + residential exposure). This allowable exposure through drinking water is used to calculate a DWLOC.

A DWLOC will vary depending on the toxic endpoint, drinking water consumption, and body weights. Default body weights and consumption values as used by the EPA's Office of Water are used to calculate DWLOCs: 2 liter (L)/70 kg (adult male), 2 L/60 kg (adult female), and 1 L/10 kg (child). Default body weights and drinking water consumption values vary on an individual basis. This variation will be taken into account in more refined screening-level and quantitative drinking water exposure assessments. Different populations will have different DWLOCs. Generally, a DWLOC is calculated for each type of risk assessment used: Acute, short-term, intermediate-term, chronic, and cancer.

When EECs for surface water and ground water are less than the calculated DWLOCs, EPA concludes with reasonable certainty that exposures to the pesticide in drinking water (when considered along with other sources of exposure for which EPA has reliable data) would not result in unacceptable levels of aggregate human health risk at this time. Because EPA considers the aggregate risk resulting from multiple exposure pathways associated with a pesticide's uses, levels of comparison in drinking water may vary as those uses change. If new uses are added in the future, EPA will reassess the potential impacts of residues of the pesticide in drinking water as a part of the aggregate risk assessment process.

1. Acute risk. Using the exposure assumptions discussed in this unit for acute exposure, the acute dietary exposure from food to pyrimethanil plus the metabolites, 4-[4,6-dimethyl-2-pyrimidinyl)amino]phenol and 4,6-dimethyl-2-(phenylamino)-5-pyrimidinol will occupy 10% of the aPAD for the U.S. population, 16% of the aPAD for females 13-49 years old, 15% of the aPAD for all infants less than 1 year old, and 31% of the aPAD for children 1-2 years old. In addition, there is potential for acute dietary exposure to pyrimethanil and 2-amino-4, 6-dimethylpyrimidine in drinking water. After calculating DWLOCs and comparing them to the EECs for surface and ground water, EPA does not expect the aggregate exposure to exceed 100% of the aPAD, as shown in the following Table 3.

Children (1-2 years old)13137.84.86,900
Females (13-49 years old)0.451637.84.833,000

2. Chronic risk. Using the exposure assumptions described in this unit for chronic exposure, EPA has concluded that exposure to pyrimethanil plus the metabolites, 4-[4,6-dimethyl-2-pyrimidinyl)amino]phenol and 4,6-dimethyl-2-(phenylamino)-5-pyrimidinol from food will utilize 1% of the cPAD for the U.S. population, 4.5% of the cPAD for all infants less than 1 year old, less than 1% of the cPAD for females 13-49 years old and 5.3% of the cPAD for children 1-2 years old. There are no residential uses for pyrimethanil that result in chronic residential exposure to pyrimethanil. Based on the use pattern, chronic residential exposure to residues of pyrimethanil is not expected. In addition, there is potential for chronic dietary exposure to pyrimethanil and 2-amino-4,6-dimethylpyrimidine in drinking water. After calculating DWLOCs and comparing them to the EECs for surface water and ground water, EPA does not expect the aggregate exposure to exceed 100% of the cPAD, as shown in the following Table 4.

Table 4.—Aggregate Risk Assessment for Chronic (Non- Cancer) Exposure to Pyrimethanil plus the metabolites, 4-[4,6-dimethyl-2- pyrimidinyl)amino]phenol and 4,6-dimethyl-2-(phenylamino)-5- pyrimidinol

Females (13-49 years old)0.17less than 15.14.85,100
Children (1-2 years)0.175.35.14.81,600

3. Short-term risk. Short-term aggregate exposure takes into account residential exposure plus chronic exposure to food and water (considered to be a background exposure level).

Pyrimethanil is not registered for use on any sites that would result in residential exposure. Therefore, the aggregate risk is the sum of the risk from food and water, which do not exceed the Agency's level of concern.

4. Intermediate-term risk. Intermediate-term aggregate exposure takes into account residential exposure plus chronic exposure to food and water (considered to be a background exposure level).

Pyrimethanil is not registered for use on any sites that would result in residential exposure. Therefore, the aggregate risk is the sum of the risk from food and water, which do not exceed the Agency's level of concern.

5. Aggregate cancer risk for U.S. population. Pyrimethanil was classified as a Group C chemical (possible human carcinogen) and a non-linear methodology MOE was applied for the estimation of human cancer risk. The chronic dietary food analyses resulted in MOEs for the U.S. population of greater than 9,000. The estimated cancer aggregate MOE for the U.S. population is 9,200.

Generally, for threshold cancer effects where the mode of action is well understood, like thyroid carcinogens such as pyrimethanil, the general margin of exposure that indicates a reasonable certainty of no harm would be 100 (representing 2 factors of 10 for inter-species and intra-species extrapolation). The question of an acceptable MOE for threshold cancer effects is a relatively recent issue; however, given that the MOE here is 9,200, there is no question that this margin demonstrates that there is a reasonable certainty of no harm from cancer effects resulting from exposure to pyrimethanil.

EPA has asked for an additional cancer study in the mouse because even at the highest dose tested there were no adverse effects. Given the dose levels used in the first mouse cancer study, EPA does not expect that even if the second study was positive it would result in a cancer risk estimate any higher than the current risk estimate. For example, the NOAEL and LOAEL from the 2 year combined chronic/carcinogenicity study in rats are 17 mg/kg/day and 221 mg/kg/day, respectively. The NOAEL (highest dose tested) from the first mouse cancer study was 210 mg/kg/day which is comparable to the LOAEL of 221 mg/kg/day in rat.

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, and to infants and children from aggregate exposure to pyrimethanil plus the metabolites, 4-[4,6-dimethyl-2-pyrimidinyl)amino]phenol and 4,6-dimethyl-2-(phenylamino)-5-pyrimidinol residues.

IV. Other Considerations

A. Analytical Enforcement Methodology

Adequate enforcement methodologies (gas chromatography/mass spectrometry Start Printed Page 52442(GS/MS) and high performance liquid chromatography/ultraviolet (HPLC-UV)) are 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; e-mail address: residuemethods@epa.gov.

B. International Residue Limits

There are no established or proposed CODEX or Mexican maximum residue limits (MRL). There is an established Canadian MRL for residues on grapes which is consistent with the recommended tolerance for grapes in this rule.

C. Conditions

1. Plantback intervals will be required for all crops other than those with registered uses.

2. Additional clarifying data will be required for Guideline 860.1300 Nature of the Residue - Livestock and 860.1380 Storage Stability.

3. A carcinogenicity study-mice (Guideline 870.4200(b) will be required because the high dose in the existing study was judged to be inadequate for assessing the carcinogenic potential of pyrimethanil.

V. Conclusion

Therefore, tolerances are established (1) for residues of pyrimethanil on almond at 0.20 ppm; almond, hulls at 12 ppm; apple, wet pomace at 12 ppm; banana at 0.10 ppm; citrus oil at 150 ppm; fruit, citrus, group 10 (post-harvest) at 10 ppm; fruit, pome, group 11 (pre-harvest and post-harvest) at 3.0 ppm; fruit, stone (except cherry), group 12 at 3.0 ppm; grape at 5.0 ppm; grape, raisin at 8.0 ppm; onion, dry bulb at 0.10 ppm; onion, green at 2.0 ppm; pistachio at 0.20 ppm; strawberry at 3.0 ppm; tomato at 0.50 ppm; and vegetable, tuberous and corm, subgroup 1C at 0.05 ppm; (2) for residues of pyrimethanil and its metabolite 4-[4,6-dimethyl-2-pyrimidinyl)amino]phenol on cattle, fat at 0.01 ppm; cattle, kidney at 0.30 ppm; cattle, meat at 0.01 ppm; cattle, meat-by-products (except kidney) at 0.01 ppm; goat, fat at 0.01 ppm; goat, kidney at 0.30 ppm; goat, meat at 0.01 ppm; goat, meat-by-products (except kidney) at 0.01 ppm; horse, fat at 0.01 ppm; horse, kidney at 0.30 ppm; horse, meat at 0.01 ppm; horse, meat-by-products (except kidney) at 0.01 ppm; sheep, fat at 0.01 ppm; sheep, kidney at 0.30 ppm; sheep, meat at 0.01 ppm; and sheep, meat-by-products (except kidney) at 0.01 ppm; and (3) for residues of pyrimethanil and its metabolite 4,6-dimethyl-2-(phenylamino)-5-pyrimidinol in milk at 0.03 ppm.

VI. Objections and Hearing Requests

Under section 408(g) of FFDCA, as amended by FQPA, any person may file an objection to any aspect of this regulation and may also request a hearing on those objections. The EPA procedural regulations which govern the submission of objections and requests for hearings appear in 40 CFR part 178. Although the procedures in those regulations require some modification to reflect the amendments made to FFDCA by FQPA, EPA will continue to use those procedures, with appropriate adjustments, until the necessary modifications can be made. The new section 408(g) of FFDCA provides essentially the same process for persons to “object” to a regulation for an exemption from the requirement of a tolerance issued by EPA under new section 408(d) of FFDCA, as was provided in the old sections 408 and 409 of FFDCA. However, the period for filing objections is now 60 days, rather than 30 days.

A. What Do I Need to Do to File an Objection or Request a Hearing?

You must file your objection or request a hearing on this regulation in accordance with the instructions provided in this unit and in 40 CFR part 178. To ensure proper receipt by EPA, you must identify docket ID number OPP-2004-0195 in the subject line on the first page of your submission. All requests must be in writing, and must be mailed or delivered to the Hearing Clerk on or before October 25, 2004.

1. Filing the request. Your objection must specify the specific provisions in the regulation that you object to, and the grounds for the objections (40 CFR 178.25). If a hearing is requested, the objections must include a statement of the factual issues(s) on which a hearing is requested, the requestor's contentions on such issues, and a summary of any evidence relied upon by the objector (40 CFR 178.27). Information submitted in connection with an objection or hearing request may be claimed confidential by marking any part or all of that information as CBI. Information so marked will not be disclosed except in accordance with procedures set forth in 40 CFR part 2. A copy of the information that does not contain CBI must be submitted for inclusion in the public record. Information not marked confidential may be disclosed publicly by EPA without prior notice.

Mail your written request to: Office of the Hearing Clerk (1900C), Environmental Protection Agency, 1200 Pennsylvania Ave., NW., Washington, DC 20460-0001. You may also deliver your request to the Office of the Hearing Clerk in Suite 350, 1099 14th St., NW., Washington, DC. The Office of the Hearing Clerk is open from 8 a.m. to 4 p.m., Monday through Friday, excluding legal holidays. The telephone number for the Office of the Hearing Clerk is (202) 564-6255.

2. Copies for the Docket. In addition to filing an objection or hearing request with the Hearing Clerk as described in Unit VI.A., you should also send a copy of your request to the PIRIB for its inclusion in the official record that is described in ADDRESSES. Mail your copies, identified by docket ID number OPP-2004-0195, to: Public Information and Records Integrity Branch, Information Resources and Services Division (7502C), Office of Pesticide Programs, Environmental Protection Agency, 1200 Pennsylvania Ave., NW., Washington, DC 20460-0001. In person or by courier, bring a copy to the location of the PIRIB described in ADDRESSES. You may also send an electronic copy of your request via e-mail to: opp-docket@epa.gov. Please use an ASCII file format and avoid the use of special characters and any form of encryption. Copies of electronic objections and hearing requests will also be accepted on disks in WordPerfect 6.1/8.0 or ASCII file format. Do not include any CBI in your electronic copy. You may also submit an electronic copy of your request at many Federal Depository Libraries.

B. When Will the Agency Grant a Request for a Hearing?

A request for a hearing will be granted if the Administrator determines that the material submitted shows the following: There is a genuine and substantial issue of fact; there is a reasonable possibility that available evidence identified by the requestor would, if established resolve one or more of such issues in favor of the requestor, taking into account uncontested claims or facts to the contrary; and resolution of the factual issues(s) in the manner sought by the requestor would be adequate to justify the action requested (40 CFR 178.32).

VII. Statutory and Executive Order Reviews

This final rule establishes a tolerance under section 408(d) of FFDCA 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 rule has Start Printed Page 52443been exempted from review under Executive Order 12866 due to its lack of significance, this rule is not subject to Executive Order 13211, Actions Concerning Regulations That Significantly Affect Energy Supply, Distribution, or Use (66 FR 28355, May 22, 2001). 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., or impose any enforceable duty or contain any unfunded mandate as described under Title II of the Unfunded Mandates Reform Act of 1995 (UMRA) (Public Law 104-4). 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); or OMB review or any Agency action under Executive Order 13045, entitled Protection of Children from Environmental Health Risks and Safety Risks (62 FR 19885, April 23, 1997). 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), Public Law 104-113, section 12(d) (15 U.S.C. 272 note). Since tolerances and exemptions that are established on the basis of a petition under section 408(d) of FFDCA, 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. In addition, the Agency has determined that this action will not have a substantial direct effect on States, on the relationship between the national government and the States, or on the distribution of power and responsibilities among the various levels of government, as specified in Executive Order 13132, entitled Federalism (64 FR 43255, August 10, 1999). Executive Order 13132 requires EPA to develop an accountable process to ensure “meaningful and timely input by State and local officials in the development of regulatory policies that have federalism implications.” “Policies that have federalism implications” is defined in the Executive Order to include regulations that have “substantial direct effects on the States, on the relationship between the national government and the States, or on the distribution of power and responsibilities among the various levels of government.” This final rule directly regulates growers, food processors, food handlers and food retailers, not States. This action does not alter the relationships or distribution of power and responsibilities established by Congress in the preemption provisions of section 408(n)(4) of FFDCA. For these same reasons, the Agency has determined that this rule does not have any “tribal implications” as described in Executive Order 13175, entitled Consultation and Coordination with Indian Tribal Governments (65 FR 67249, November 6, 2000). Executive Order 13175, requires EPA to develop an accountable process to ensure “meaningful and timely input by tribal officials in the development of regulatory policies that have tribal implications.” “Policies that have tribal implications” is defined in the Executive Order to include regulations that have “substantial direct effects on one or more Indian tribes, on the relationship between the Federal Government and the Indian tribes, or on the distribution of power and responsibilities between the Federal Government and Indian tribes.” This rule will not have substantial direct effects on tribal governments, on the relationship between the Federal Government and Indian tribes, or on the distribution of power and responsibilities between the Federal Government and Indian tribes, as specified in Executive Order 13175. Thus, Executive Order 13175 does not apply to this rule.

VIII. Congressional Review Act

The Congressional Review Act, 5 U.S.C. 801 et seq., as added by the Small Business Regulatory Enforcement Fairness Act of 1996, generally provides that before a rule may take effect, the agency promulgating the rule must submit a rule report, which includes a copy of the rule, to each House of the Congress and to the Comptroller General of the United States. 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 this final rule in the Federal Register. This final rule is not a “major rule” as defined by 5 U.S.C. 804(2).
