II. Background and Statutory Findings

In the Federal Register of January 9, 2003 (68 FR 1182) (FRL-7287-7), EPA issued a notice pursuant to section 408 of FFDCA, 21 U.S.C. 346a, as amended by FQPA (Public Law 104-170), announcing the filing of a pesticide petition (PP 2E6512) by Makhteshim-Agan of North America Inc., 551 Fifth Ave., Suite 1100 New York, NY 10176. That notice included a summary of the petition prepared by Makhteshim-Agan of North America Inc., the registrant. There were no comments received in response to the notice of filing.

The petition requested that 40 CFR 180.191 be amended by establishing a tolerance for residues of the fungicide folpet, (N-(trichloromethylthio)phthalimide), in or on hop at 120 parts per million (ppm).

Section 408(b)(2)(A)(i) of the 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 the 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 the FFDCA requires EPA to give special consideration to Start Printed Page 10378exposure 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 the FFDCA and a complete description of the risk assessment process, see the final rule on Bifenthrin Pesticide Tolerances (62 FR 62961, November 26, 1997) (FRL-5754-7).

III. Aggregate Risk Assessment and Determination of Safety

Consistent with section 408(b)(2)(D) of the 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 the FFDCA, for a tolerance for residues of folpet on hop, dried cones at 100 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 folpet 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.

870.7485Metabolism and pharmacokineticsDoses: 50 and 5,000 ppm. Results: The 5,000 ppm level had been shown to cause the tumors in mice but not in rats. The studies suggested that folpet was tumorigenic in the mouse and not in the rat because: Greater intake in the mouse and greater target tissue exposure to active metabolites that the mouse could not detoxify; greater local effects on mouse upper gastrointestinal tract; and greater reliance by the mouse on glutathione for detoxification of folpet.
870.7485Metabolism and pharmacokineticsC14-Folpet was administered orally to Sprague-Dawley rats in 3 studies: 1. Single dose of 10 mg/kg; 2. Single dose of 500 mg/kg; and 3. On day 15, 10 mg/kg of C14-Folpet after 14 consecutive days of unlabeled folpet at 10 mg/kg. Samples were examined for radioactivity for up to 120 hours post C14-dosing. Results: 1. Single C14-Folpet at 10 mg/kg was absorbed > 90% of the dose, there was rapid urinary excretion and by 120 hours, there was little detactable radioactivity. 2. Single C14-Folpet at 500 mg/kg was about 60% absorbed with the urinary excretion rate being slower that after the 10 mg/kg dose (possibly due to rate-limiting absorption). 3. Single C14-Folpet at 10 mg/kg following 14 daily non-labeled doses of 10 mg/kg yielded results similar to those observed after a single c14 dose. 4. No accumulation of folpet was detected during the 5 days after dosing; concentrations of radioactivity in measured tissues were generally below the limit of detection at 10 mg/kg or were detected at very low levels at 500 mg/kg. 5. Phthalamic acid was determined to be the single active metabolite found in urine & it was suggested that its formation from Folpet may have been by trichloro- methylthio groups loss and hydrolytic cleavage of the maleimide ring. At 10 mg/kg,the major fecal metabolite was phthalamic acid and at 500 mg/kg, the radioactivity was primarily associated with unchanged C14-folpet (assumed to be unabsorbed test article).
870.7600Dermal penetrationDoses: C14-Folpet was administered dermally to male doses of 10, 1, 0.1, and 0.01 mg/rat (200 uL volume of test suspension to 18.9 cm2 of clipped skin) for up to 24 hours. Blood, urine, feces, carcass and skin radioactivity was measured (up to 24 hrs). Results: 1. Rapid absorption into the skin and carcass; 2. Low blood levels; 3. Primary excretion by urine with rate apparently inversely related to quantity applied; and 4. Minor bile involvement in excretion as little in feces.

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 the LOAEL 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 intra species differences.

For dietary risk assessment (other than cancer) the Agency uses the UF to calculate an acute or chronic reference dose (acute RfD or chronic RfD) where the RfD is equal to the NOAEL divided by the appropriate UF (RfD = NOAEL/UF). Where an additional safety factors (SF) is retained due to concerns unique to the FQPA, 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 FQPA SF.

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 is expressed as 1 x 10-6 or one in a million). 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 folpet used for human risk assessment is shown in Table 2 of this unit:

C. Exposure Assessment

1. Dietary exposure from food and feed uses. Tolerances have been established (40 CFR 180.191) for the residues of folpet, in or on a variety of raw agricultural commodities. Risk assessments were conducted by EPA to assess dietary exposures from folpet 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 one day or single exposure. The Dietary Exposure Evaluation Model-Food Commodity Intake Database (DEEM-FCIDTM) analysis evaluated the individual food consumption 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 following assumptions were made for the acute exposure assessments: Anticipated residues for most commodities and percent crop treated for many commodities. For hop, the dietary exposure analysis assumed tolerance level residues and 100 percent crop treated.

ii. Chronic exposure. In conducting this chronic dietary risk assessment the Dietary Exposure Evaluation Model Food Commodity Intake Database (DEEM FCID) analysis evaluated the individual food consumption 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 following assumptions were made for the chronic exposure assessments: Anticipated residues for most commodities and percent crop treated for many commodities. For hop, the dietary exposure analysis assumed tolerance level residues and 100 percent crop treated.

iii. Cancer. In conducting this cancer dietary risk assessment the Dietary Exposure Evaluation Model Food Commodity Intake Database (DEEM-FCIDTM) analysis evaluated the individual food consumption 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 following assumptions were made for the chronic exposure assessments: Anticipated residues for most commodities and percent crop treated for many commodities. For hop, the dietary exposure analysis assumed tolerance level residues and 100 percent crop treated.

iv. Anticipated residue and percent crop treated (PCT) information. Section 408(b)(2)(E) of the 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 the 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.

The Agency did use anticipated residue calculations in conducting its risk assessment. These calculations are based upon submitted field trial data and could be further refined through the use of monitoring data.

Section 408(b)(2)(F) of the 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 contain 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 the FFDCA, EPA may require registrants to submit data on PCT.

The Agency used PCT information as follows. The only registered food use of folpet in the United States is avocados grown in Florida. According to data available from the United States Department of Agriculture's National Agricultural Statistics Service, California accounted for 89 percent of avocado production in the United States, followed by Florida at nearly 11 percent and Hawaii at approximately 0.1 percent. Therefore, the Agency has assumed that only 11 percent of the U.S. avocado crop is treated with folpet. As stated earlier, for the hop use, the Agency assumed 100 percent crop treated even though imports of hop accounted for less than 50 percent of the crop consumed in the United States, based upon data available from the Hop Growers of American 2001 Statistical Report. For all other commodities (except hops and avocados), the Agency assumed a maximum percent crop treated value of 1% for each commodity (i.e., apple, cranberry, cucumber, grape, lettuce, melon, onion, strawberry, and tomato) based upon information derived through an analysis of import and domestic production data available from the United States Department of Agriculture for the years 1995 through 1999 and adjusted for the countries in which folpet is registered.

The Agency believes that the three conditions listed in Unit III. have been met. With respect to Condition 1, PCT estimates are derived from Federal and private market survey data, which are reliable and have a valid basis. In using these data, the Agency also took into account the specific countries where folpet is registered. In the case of avocados, the Agency based its PCT estimate on the volume of the avocado crop grown in the United States, utilizing data from the U.S. Department of Agriculture. For all potentially-treated commodities, EPA used estimated maximum PCT assumptions in conducting both the acute and chronic dietary exposure assessments. The exposure estimates resulting from this approach reasonably represent the highest levels to which an individual could be exposed, and are unlikely to underestimate an individual's acute dietary exposure. The Agency is reasonably certain that the percentage of the food treated is not likely to be an underestimation. 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 Start Printed Page 10383folpet 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 folpet 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 folpet.

The Agency uses the First Index Reservoir Screening Tool (FIRST) or the Pesticide Root Zone/Exposure Analysis Modeling System (PRZM/EXAMS), to produce estimates of pesticide concentrations in an index reservoir. The SCI-GROW model is used to predict pesticide concentrations in shallow groundwater. For a screening-level assessment for surface water EPA will use FIRST (a tier 1 model) before using PRZM/EXAMS (a tier 2 model). The FIRST model is a subset of the PRZM/EXAMS model that uses a specific high-end runoff scenario for pesticides. While both FIRST and PRZM/EXAMS incorporate an index reservoir environment, 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 coarse screen for sorting out pesticides for which it is highly unlikely that drinking water concentrations would ever 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) from these models to quantify drinking water exposure and risk as a %RfD or %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 folpet they are further discussed in the aggregate risk sections in Unit III.E..

Based on the FIRST and SCI-GROW models the estimated environmental concentrations (EECs) of folpet for acute exposures are estimated to be 309 parts per billion (ppb) for surface water and 0.83 ppb for ground water. The EECs for chronic exposures are estimated to be 0.62 ppb for surface water and 0.83 ppb for ground 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).

Folpet is currently registered for use as an additive in paints and stains for use both occupationally and by the homeowner. Four major exposure scenarios for homeowner handlers using folpet containing paints and stains labeled for pesticidal use and three major scenarios for homeowners using folpet containing products not labeled for pesticidal use were evaluated. The highest exposure level for combined inhalation and dermal exposures were based upon a homeowner applying a ready-to-use stain formulation with an airless sprayer. This exposure level was used to estimate the short- and intermediate-term risks for folpet.

4. Cumulative exposure to substances with a common mechanism of toxicity. Section 408(b)(2)(D)(v) of the 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 does not have, at this time, available data to determine whether folpet has a common mechanism of toxicity with other substances or how to include this pesticide in a cumulative risk assessment. Unlike other pesticides for which EPA has followed a cumulative risk approach based on a common mechanism of toxicity, folpet 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 folpet 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 final rule for Bifenthrin Pesticide Tolerances (62 FR 62961, November 26, 1997).

Captan and folpet share a common metabolite, thiophosgene, which the Agency believes to be responsible for the carcinogenic effects of these compounds. Thiophosgene is a highly reactive, short-lived compound. Studies indicate that thiophosgene causes local irritation of the site with which it comes in contact, and is believed to cause tumors through irritation of the duodenum. Because they are so short-lived, thiophosgene residues cannot be quantified. Without measurable residues of the common metabolite, it is difficult to relate exposures of captan to those of folpet since the formation of thiophosgene may be different for both compounds. However, assuming that the carcinogenic effects observed in both pesticides are due solely to the metabolite thiophosgene, the Agency believes it is reasonable to add the estimate cancer risks from the individual aggregate risks from both folpet and captan to obtain a worst-case estimate.

D. Safety Factor for Infants and Children

1. In general. Section 408 of the FFDCA provides that EPA shall apply an additional tenfold 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 data base on toxicity and exposure unless EPA determines that a different margin of safety will be safe for infants and children. Margins of safety are incorporated into EPA risk assessments either directly through use of a MOE analysis or through using uncertainty (safety) factors in calculating a dose level that poses no appreciable risk to humans.

2. Prenatal and postnatal sensitivity. The data provided no indication of increased susceptibility in two prenatal developmental toxicity studies in rats following in utero or in the two (2) 2-generation reproduction studies in rats. Two developmental toxicity studies in rabbits are also available. In a study with New Zealand rabbits, folpet caused an increase in the incidence of hydrocephalus in fetuses and with the associated dome skull and irregularly-shaped fontanelles at the mid and high dose groups in the presence of maternal toxicity. Both fetal and litter incidences of this malformation were increased in a dose-related manner. There were no toxicological effects noted on litter size, resorptions, sex ratio, or number of skeletal malformations. For maternal toxicity, the NOAEL was 10 mg/kg/day and the LOAEL was 20 mg/kg/day, based on decreased body weight gain and food consumption. For developmental toxicity, the NOAEL was Start Printed Page 1038410 mg/kg/day and the LOAEL was 20 mg/kg/day, based upon an increase in the number of fetuses and litters with hydrocephaly and related skull malformations. Although the developmental malformations (hydrocephaly) and associated maternal toxicity occur at similar doses, such effects are toxic manifestations as a result of exposure.

In order to determine the critical period of treatment for the occurrence of hydorcephaly and other treatment-related fetal anomalies observed in the above study, another developmental toxicity study was conducted with the same strain of rabbit with the highest dose group (60 mg/kg/day) receiving folpet on gestation days 7-9, 10-12, 13-15, or 16-18. The incidence of hydrocephalus was higher than historical or concurrent controls, but lower than in the previous study. The maternal toxicity noted was a dose-related decreased food consumption and variable decrease in body weight gain. Significantly increased incidence of irregularly-shaped fontanelles and slightly increased incidences of angulated hyoid alae were noted in the 60 mg/kg/day dose group.

In a second rabbit developmental toxicity study, HY/CR strain rabbits received folpet on gestation days 7 through 19. For maternal toxicity, the NOAEL was 40 mg/kg/day and the LOAEL was 160 mg/kg/day, based on decreased body weights and food consumption as well as clinical signs. For developmental toxicity, the NOAEL was 10 mg/kg/day and the LOAEL was 40 mg/kg/day, based on delayed ossification of the sternebrae. There was no evidence of hydrocephaly observed in this study at dose levels greater than in the previous study.

In addition, the Agency examined the available studies for captan, the structural analog of folpet, and determined that there was no indication of increased susceptibility of rabbits or hamsters to pre- or post-natal exposure to captan. In prenatal developmental toxicity studies in rabbits and hamsters and reproduction studies in the rat, all conducted using captan as the test material, toxicity to the offspring occurred at equivalent or higher doses than maternal toxicity.

3. Conclusion. i. There is a complete toxicity data base for folpet and exposure data are complete or are estimated based on data that reasonably accounts for potential exposures. The Agency has determined that the FQPA Safety Factor can be reduced to 1X based upon the following weight-of-the-evidence considerations:

a. There was no evidence of quantitative or qualitative susceptibility in two developmental toxicity studies in the rat;

b. There was no evidence of enhanced suspectibility to the pups in two different 2-generation reproduction studies in the rat;

c. Folpet is not a cholinesterase inhibitor and, therefore, comments made at the June 26-27, 2002 Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA) Scientific Advisory Panel (SAP) meeting on the Determination of the Appropriate FQPA Safety Factor(s) in the Organophosphorous Pesticide Cumulative Risk Assessment: Susceptibility and Sensitivity to the Common Mechanism, Acetylcholinesterase Inhibition should not influence this uncertainty factor decision.

d. There is inconsistency between the two available developmental toxicity studies in the rabbit. When tested at lower doses, there is a concern for hydrocephaly. However, when this study was repeated in the same strain of rabbit at higher dose levels, no evidence of hydrocephaly was observed. Nevertheless, for purposes of risk assessment, the Agency has selected the developmental NOAEL of 10 mg/kg/day from the rabbit developmental study in which hydrocephaly was observed as the endpoint for evaluating acute risk.

e. Other than the one rabbit developmental toxicity study, there are no other signs from the available toxicology database of a concern for neurotoxic effects.

f. Furthermore, the Agency's exposure assumptions are conservative. The assessment assumes that all hops consumed in the United States are treated with folpet. In addition, the analysis presumes that all avocados grown in Florida are treated with this fungicide. The percent crop treated data for the imported commodities assumed that all crop exported to the U.S. from countries in which folpet is registered are treated with this chemical. Therefore, a figure of 1% crop treated was assumed for the following commodities: Apple, cranberry, cucumber, grape, lettuce, melon, onion, strawberry, and tomato.

ii. The Agency has also determined that a developmental neurotoxicity study for folpet is not warranted based upon the following considerations:

a. Although hydrocephalus was observed in one developmental toxicity study in the rabbit, it occurred at maternally toxic doses and was only seen in one species;

b. No alterations to the fetal nervous system were seen in the developmental rat studies at the same doses that induce hydrocephaly in rabbits;

c. Although there are no acute or subchronic neurotoxicity studies available, there is no evidence of neurotoxicity or neuropathology in adult animals in any of the studies;

d. The available data indicate that the developmental neurotoxicity study would have to be tested at dose levels higher than 150 mg/kg/day because no developmental toxicity was observed in rats at 2,000 mg/kg/day. In addition, given the results in the 2-generation reproduction study (NOAEL of 168 mg/kg/day), it is anticipated that in order to elicit any fetal nervous system abnormalities in the developmental neurotoxicity study, the selected dose levels would have to be higher than 160 mg/kg/day.

e. Since the dose level selections for the developmental neurotoxicity study would be greater than 160 mg/kg/day, the resultant NOAEL would be either comparable to, or higher than, the doses currently used in the risk assessment. The NOAEL of 10 mg/kg/day selected for the acute reference dose and the residential exposure and risk assessments is seventeen times lower than the offspring NOAEL in the reproduction study. The NOAEL of 9 mg/kg/day selected for the chronic reference dose is nineteen times lower than the offspring NOAEL in the reproduction study. Therefore, it is unlikely that the developmental neurotoxicity study would change the current doses used for overall risk assessments.

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 the model estimates of a pesticide's concentration in water (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 Start Printed Page 10385as used by the Office of Water are used to calculate DWLOCs: 2 liter (L)/70 kg (adult male), 2L/60 kg (adult female), and 1L/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 groundwater are less than the calculated DWLOCs, OPP concludes with reasonable certainty that exposures to the pesticide in drinking water (when considered along with other sources of exposure for which OPP has reliable data) would not result in unacceptable levels of aggregate human health risk at this time. Because OPP 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, OPP 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 folpet will occupy <1 % of the aPAD for females 13 years and older. In addition, there is potential for acute dietary exposure to folpet 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 Table 3 of this unit:

Table 3.—Aggregate Risk Assessment for Acute Exposure to Folpet

Population SubgroupaPAD (mg/kg/day)% aPAD (Food)Surface Water EEC (ppb)Ground Water EEC (ppb)Acute DWLOC (ppb)
Females, 13-49 years old0.1<13090.832,800

2. Chronic risk. Using the exposure assumptions described in this unit for chronic exposure, EPA has concluded that exposure to folpet from food will utilize less than 1% of the cPAD for all population subgroups within the United States. Based the use pattern, chronic residential exposure to residues of folpet is not expected. In addition, there is potential for chronic dietary exposure to folpet 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 cPAD, as shown in Table 4 of this unit:

Table 4.—Aggregate Risk Assessment for Chronic (Non-Cancer) Exposure to Folpet

Population SubgroupcPAD mg/kg/day% cPAD (Food)Surface Water EEC (ppb)Ground Water EEC (ppb)Chronic DWLOC (ppb)
U.S. population0.09<1%0.620.833,100
All Infants0.09<1%0.620.83900
Children, 1-2 years0.09<1%0.620.83900
Females, 13-49 years0.09<1%0.620.832,700
Adults, 50+ years0.09<1%0.620.833,100

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

Folpet is currently registered for use that could result in short-term and intermediate-term residential exposure and the Agency has determined that it is appropriate to aggregate chronic food and water and short-term and intermediate-term exposures for folpet.

Using the exposure assumptions described in this unit for short-term and intermediate-term exposures, EPA has concluded that food and residential exposures aggregated result in aggregate MOEs of 370. These aggregate MOEs do not exceed the Agency's level of concern for aggregate exposure to food and residential uses. In addition, short-term and intermediate-term DWLOCs were calculated and compared to the EECs for chronic exposure of folpet in ground and surface water. After calculating DWLOCs and comparing them to the EECs for surface and ground water, EPA does not expect short-term or intermediate-term aggregate exposures to exceed the Agency's level of concern, as shown in Table 5 of this unit:

Table 5.—Aggregate Risk Assessments for Short-Term and Intermediate-Term Exposures to Folpet

Population SubgroupAggregate MOE (Food + Residential)Aggregate Level of Concern (LOC)Surface Water EEC (ppb)Ground Water EEC (ppb)DWLOC (ppb)
Females, 13-49 years3701000.620.832,200
Start Printed Page 10386

4. Aggregate cancer risk for U.S. population. The aggregate cancer risk (food plus residential) from exposure to folpet is estimated to be 7.2 x 10-8. Assuming a negligible risk level of 1.0 x 10-6, the cancer DWLOC would be 15 ppb. Based on the FIRST and SCI-GROW models the EECs for chronic exposures to folpet are estimated to be 0.62 ppb for surface water and 0.83 ppb for ground water, significantly lower than the DWLOC.

As discussed in Unit III.C.4., captan and folpet share a common metabolite, thiophosgene, which the Agency believes to be responsible for the carcinogenic effects of these compounds. Thiophosgene is a highly reactive, short-lived compound. Studies indicate that thiophosgene causes local irritation of the site with which it comes in contact, and is believed to cause tumors through irritation of the duodenum. Because they are so short-lived, thiophosgene residues cannot be quantified. Without measurable residues of the common metabolite, it is difficult to relate exposures of captan to those of folpet since the formation of thiophosgene may be different for both compounds. However, assuming that the carcinogenic effects observed in both pesticides are due solely to the metabolite thiophosgene, the Agency believes it is reasonable to add the estimate cancer risks from the individual aggregate risks from both folpet and captan to obtain a worst-case estimate.

For captan, the estimated cancer risk for the U.S. population from exposure to food only is 1.26 x 10-7. As discussed above, the estimate cancer risk (food only) from exposure to folpet is 7.2 x 10-8. If these two risk estimates are added together, the total estimated cancer risk is 2.0 x 10-7. Assuming a negligible cancer risk in the range of 1.0 x 10-6 to 3.0 x 10-6, the smallest cancer DWLOC would be 11 ppb. Based on the FIRST and SCI-GROW models the EECs for chronic exposures to folpet are estimated to be 0.62 ppb for surface water and 0.83 ppb for ground water. The EECs for chronic exposure to captan are estimated to be 4 ppb for surface water and 1 ppb for groundwater. The combined EECs for chronic exposure to captan plus folpet are 5 ppb for surface water and 2 ppb for groundwater, both below the DWLOC of 11 ppb.

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, and to infants and children from aggregate exposure to folpet residues.

IV. Other Considerations

A. Analytical Enforcement Methodology

An adequate gas chromatography/electron capture detector (GC/ECD) analytical method is available for enforcing tolerances of folpet in or on 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; e-mail address: residuemethods@epa.gov.

B. International Residue Limits

No CODEX MRLs exist for folpet on hop.

V. Conclusion

Therefore, the tolerance is established for residues of folpet, (N-(trichloromethylthio)phthalimide), in or on hop, dried cones at 120 ppm.

VI. Objections and Hearing Requests

Under section 408(g) of the FFDCA, as amended by the 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 the FFDCA by the FQPA, EPA will continue to use those procedures, with appropriate adjustments, until the necessary modifications can be made. The new section 408(g) of the 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 the FFDCA. However, the period for filing objections is now 60 days, rather than 30 days.

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 the 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 been 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 the 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 the 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).
