Aureobasidium pullulans, 8731-8736 [2012-3585]

Download as PDF 8731 Federal Register / Vol. 77, No. 31 / Wednesday, February 15, 2012 / Rules and Regulations need to determine and issue new interest assumptions promptly so that the assumptions can reflect current market conditions as accurately as possible. Because of the need to provide immediate guidance for the payment of benefits under plans with valuation dates during March 2012, PBGC finds that good cause exists for making the assumptions set forth in this amendment effective less than 30 days after publication. PBGC has determined that this action is not a ‘‘significant regulatory action’’ under the criteria set forth in Executive Order 12866. Because no general notice of proposed rulemaking is required for this amendment, the Regulatory Flexibility Act of 1980 does not apply. See 5 U.S.C. 601(2).

Background and Statutory Findings In the Federal Register of March 10, 2010 (75 FR 11171) (FRL–8810–8), EPA issued a notice pursuant to section 408(d)(3) of FFDCA, 21 U.S.C. 346a(d)(3), announcing the filing of a pesticide tolerance petition (PP 9F7623) by Bio-ferm GmbH, Konrad Lorenz Str. 20, Tulln, 3430, Austria. The petition requested that 40 CFR part 180 be amended by establishing an exemption from the requirement of a tolerance for residues of Aureobasidium pullulans strains DSM 14940 and DSM 14941. This notice referenced a summary of the petition prepared by the petitioner Bioferm GmbH, which is available in the docket, https://www.regulations.gov. There were no comments received in response to the notice of filing. Section 408(c)(2)(A)(i) of FFDCA allows EPA to establish an exemption from the requirement for a tolerance (the legal limit for a pesticide chemical residue in or on a food) only if EPA determines that the exemption is ‘‘safe.’’ Section 408(c)(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. Pursuant to section 408(c)(2)(B) of FFDCA, in establishing or maintaining in effect an exemption from the requirement of a tolerance, EPA must take into account PO 00000 Frm 00016 Fmt 4700 Sfmt 4700 the factors set forth in section 408(b)(2)(C) of FFDCA, which require 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. * * *’’ Additionally, section 408(b)(2)(D) of FFDCA requires that 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 performs a number of analyses to determine the risks from aggregate exposure to pesticide residues. First, EPA determines the toxicity of pesticides. Second, EPA examines exposure to the pesticide through food, drinking water, and through other exposures that occur as a result of pesticide use in residential settings. III. Toxicological Profile 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 and considered its validity, completeness, and reliability and the relationship of this information 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. A. Overview of Aureobasidium Pullulans Strains DSM 14940 and DSM 14941 Aureobasidium pullulans is a ‘‘yeastlike’’ saprophytic fungus found in the phyllosphere of many plants, and it has been isolated from soil and aquatic environments (Refs. 1, 2, and 3). It is commonly isolated from healthy grape (Refs. 4 and 5) and apple (Ref. 6) plants, as well as other plants (Refs. 7, 8, 9, 10, and 11). Although associated with disease in some plants, the fungus generally is recognized as a saprobe, since it derives its nourishment from nonliving or decaying organic matter, and is only considered a weak pathogen or parasite of certain plants (Refs. 2 and 12). It is a known antagonist of several plant disease-causing organisms, and is an important producer of enzymes for biotechnological and industrial applications (Ref. 1). Aureobasidium pullulans strains DSM 14940 and DSM 14941 were isolated from apple leaves and classified by the German Strain Collection for Microorganisms (DSMZ). Neither is a E:\FR\FM\15FER1.SGM 15FER1 Federal Register / Vol. 77, No. 31 / Wednesday, February 15, 2012 / Rules and Regulations erowe on DSK2VPTVN1PROD with RULES mutant nor genetically modified strain and they are not closely related to toxigenic human pathogens. As discussed in Pesticide Petition (PP) 9F7623, product analysis data demonstrate that Aureobasidium pullulans strain DSM 14941 is closely related to strain DSM 14940. The two strains share many similar genetic and morphological characteristics. Bioferm GmbH has proposed to register two manufacturing-use pesticide products (MPs): ‘‘Aureobasidium pullulans strain DSM 14941 Technical,’’ and ‘‘Aureobasidium pullulans strain DSM 14940 Technical.’’ The active ingredient is 80% w/w (minimum of × 109 colony forming units/grams (unit of measure for bacteria (cfu/g)) in each of the proposed technical products. Bio-ferm GmbH has proposed to register two end-use products (EPs) containing equal parts of Aureobasidium pullulans strains DSM 14940 and DSM 14941: ‘‘Blossom Protect’’ will be applied to pome fruit only during the blossoming period to protect plants against bacterial fire blight, and ‘‘Botector’’ will be applied preharvest to grapes, pome fruit, stone fruit, and strawberries to protect these crops against fruit rot diseases caused by Botrytis sp., Monilia sp., Penicillium sp., Nectria sp., and Pezicula sp. B. Microbial Pesticide Toxicology Data Requirements The Agency has determined that, for preharvest uses, all mammalian toxicology data requirements submitted to support the petition to exempt residues of Aureobasidium pullulans strains DSM 14940 and DSM 14941 from the requirement of a tolerance have been fulfilled (Ref. 13). The product analysis data demonstrated that Aureobasidium pullulans strain DSM 14941 is closely related to strain DSM 14940. Because the strains are closely related, the Agency has determined that the findings of the submitted acute toxicity/ pathogenicity studies conducted only with strain DSM 14941 supported both strains, and those studies show no evidence of toxicity, or pathogenicity at the doses tested. In addition, both strains were tested in an acute subcutaneous injection toxicity/ pathogenicity study in rats. The results of this study indicated that both strains were not toxic, infective, and/or pathogenic to the test animals. These findings were supported by the results of a study of the influence of temperature on the growth of the two Aureobasidium pullulans strains, which showed that growth of both strains does not occur at or above 35 °C. Since VerDate Mar<15>2010 14:28 Feb 14, 2012 Jkt 226001 human body temperature is 37 °C, and based on the results from these studies as discussed in this unit the Agency concluded that neither strain would be toxic, infective and/or pathogenic in humans. 1. Acute Oral Toxicity/Pathogenicity (Office of Chemical Safety and Pollution Prevention (OCSPP) Guideline 885.3050; Master Record Identification Number (MRID) No. 47899302. Twenty-four rats were administered a single dose of Aureobasidium pullulans strain DSM 14941. Three animals of each sex were sacrificed on days 3, 7, and 14; the remaining animals were sacrificed at test end on day 21. Body tissues were examined for Aureobasidium pullulans. All samples of feces, blood, brain, lung, liver, kidney, spleen, stomach, and intestine were negative. The lymph nodes of one animal sacrificed on day 7 tested positive for the presence of Aureobasidium pullulans DSM 14941. These findings show a pattern of clearance with no Aureobasidium pullulans DSM 14941 detected by day 14. The results of this acceptable study demonstrated that Aureobasidium pullulans DSM 14941 was not toxic, infective, and/or pathogenic in rats, when dosed at 4 × 108 cfu/animal. 2. Acute Pulmonary Toxicity/ Pathogenicity (OCSPP Guideline 885.3150; MRID No. 47899303). Male and female animals were exposed intratracheally with Aureobasidium pullulans strain DSM 14941 Technical (4 × 108 cfu/g). Interim sacrifices were made 3 hours post-dose and on study days 3, 7, and 14; the remaining animals were sacrificed at study end on day 21. There was no mortality, and, except on the day of dosing when the entire test material group showed reduced motor activity and dyspnea, all animals appeared normal throughout the study. Tissue samples were evaluated for Aureobasidium pullulans after sacrifice. The following tissues were negative for Aureobasidium pullulans at all time points: Feces, brain, kidney, and intestine. Blood samples were negative except for one male on day 0; lung samples were negative except for two males and two females on day 0; liver samples were negative except for three males on day 0; spleen samples were negative except for two males on day 0; lymph node samples were negative except for one animal on day 7, and stomach samples were negative except for two males on day 0. These findings show a pattern of clearance with no Aureobasidium pullulans DSM 14941 detected by day 14. The results of this acceptable study demonstrated that Aureobasidium pullulans DSM 14941 was not toxic, infective, and/or PO 00000 Frm 00017 Fmt 4700 Sfmt 4700 8733 pathogenic in rat, when dosed at 0.8 × 108 cfu/animal. 3. Acute Injection Toxicity/ Pathogenicity (OCSPP Guideline 885.3200; MRID No. 47871807 and 47871808). In an acute subcutaneous toxicity/pathogenicity study (MRID 47871807), male and female rats were injected with Aureobasidium pullulans strain DSM 14940 (2.36 × 1010 cfu/g) and DSM 14941 (1.5 × 1010 cfu/g). Interim sacrifices were made on days 3, 7, and 14; the remaining animals were sacrificed at test end on day 21. There were no deaths, and all animals appeared normal throughout the study except for edema or slight erythema at the injection site. Samples of the following tissues were negative for Aureobasidium pullulans at all time points: Feces, blood, brain, lung, liver, kidney, spleen, stomach, and intestine. Lymph node samples were negative except for one animal sacrificed on day 7. The study author suggested this was likely a post-mortem transmission. A pattern of clearance was observed in this study, with no Aureobasidium pullulans DSM 14941 or 14940 detected by day 14. The results of this acceptable study demonstrated that Aureobasidium pullulans strains DSMZ 14940 and DSMZ 14941 were not toxic, infective, and/or pathogenic in rats, when dosed at 1.95 × 107 or 1.12 × 107cfu/animal, respectively. In a second acute subcutaneous toxicity/pathogenicity study (MRID 47871808), male and female rats were injected with Aureobasidium pullulans strain DSM 14941 (1.1 × 109 cfu/g). Interim sacrifices were made on days 1 and 7; the remaining animals were sacrificed at test end on day 21. There were no deaths, and all animals appeared normal throughout the study except for severe edema or slight erythema at the injection site. Samples of the following tissues were negative for Aureobasidium pullulans at all time points: Brain, lung, spleen, kidney, lymph nodes, blood and urine. The skin was positive for Aureobasidium pullulans in three males and three females from the test material group on day 1 and in two females of the same group on day 7. The liver of one male from the test material group was positive on day 1. The cecum contents were positive in one male and one female from the test material group on day 1 and in two females from the same group on day 7. These findings show a pattern of clearance with no Aureobasidium pullulans DSM 14941 detected by day 21. The results of this acceptable study demonstrated that Aureobasidium pullulans DSM 14941 was not toxic, infective, and/or E:\FR\FM\15FER1.SGM 15FER1 erowe on DSK2VPTVN1PROD with RULES 8734 Federal Register / Vol. 77, No. 31 / Wednesday, February 15, 2012 / Rules and Regulations pathogenic in rats, when dosed at 1.6 × 107 cfu/animal. 4. Acute Dermal Toxicity (OCSPP Guideline 870.1200; MRID 47869615). In an acute dermal toxicity study, the shaved skin of 10 rats was dosed with 2,000 milligram/kilogram (mg/kg) Blossom Protect (7 × 109 cfu/g each of strains DSM 14940 and DSM 14941) for 24 hours. One male exhibited chromodacryorrhea from day 7 to day 14 and one female exhibited chromodacryorrhea from day 1 to day 2 of the study, but this was not considered to be toxicologically significant because this is a normal but rare response and it did not result in mortality. All animals appeared healthy at necropsy. The lethal dose (LD50) was >2,000 mg/ kg. This study was rated acceptable, and the end use product (EP) is classified as toxicity category IV. 5. Primary Dermal Irritation (OCSPP Guideline 870.2500; MRID 47869619). In a dermal irritation study, the shaved skin of 3 rabbits was dosed with 0.5 g Blossom Protect (7 × 109 cfu/g Aureobasidium pullulans strain DSM 14940 and 7 × 109 cfu/g Aureobasidium pullulans strain DSM 14941) moistened with 1.0 milliliter (mL) deionized water for 4 hours. All animals appeared normal throughout the study; thus, Blossom Protect was considered to be non-irritating. This study was rated acceptable, and the EP is classified as toxicity category IV. 6. Acute Oral Toxicity (OCSPP Guideline 870.1100; MRID No. 47869614. In an acute oral toxicity study, six animals received a single 2,000 mg/kg body weight (bw) dose of Blossom Protect 22% (2 × 1010 cfu/g) Aureobasidium pullulans strain DSM 14940, 22% (2 × 1010 cfu/g) Aureobasidium pullulans strain DSM 14941, 25% sucrose, 6% water. There was no mortality, and all animals appeared normal throughout the study. The LD50 was >2,000 mg/kg. This study was rated acceptable, and the EP is classified as toxicity category III. 7. Acute Inhalation Toxicity (OCSPP Guideline 870.1300; MRID 47869617). In an acute inhalation toxicity study, 10 animals were exposed nose-only to a 10% suspension of Blossom Protect (7 × 10 9 cfu/g A. pullulans strain DSM 14940 and 7 × 109 cfu/g A. pullulans strain DSM 14941) at 5.17 milligrams per liter (mg/L). The Mass Medium Aerodynamic Diameter (MMAD) was 4.2 mm. There were no deaths and all animals appeared healthy throughout the study. Necropsy was unremarkable. The lethal concentration (LC50) was >5.17 mg/L. This study was rated acceptable, and the EP is classified as toxicity category IV. VerDate Mar<15>2010 14:28 Feb 14, 2012 Jkt 226001 8. Acute Eye Irritation (OCSPP Guideline 870.2400; MRID 47869618). In an eye irritation study, three rabbits were dosed with 0.1 mL (60–62 grams (g) of Blossom Protect (7 × 109 cfu/g A. pullulans strain DSM 14940 and 7 × 109 cfu/g A. pullulans strain DSM 14941). One animal had a score of 1 for conjunctival redness 1 hour after application. There were no other clinical signs, and all animals appeared normal at 24 hours. Blossom protect was considered to be virtually non-irritating. This study was rated acceptable, and the EP is classified as toxicity category IV. 9. In vivo Micronucleus Assay (MRID 47899304). Twenty mice (two groups of five male and two groups of five female mice) received single 2,000 mg/kg Aureobasidium pullulans strain DSM 14941 dissolved in water by oral gavage. There were no clinical signs observed in any of the test animals, which were sacrificed 24 or 48 hours after receiving the test material. The femoral bone marrow was immediately harvested, and the ratio of polychromatic erythrocytes to total erythrocytes (mature and immature) was determined, and 2,000 immature erythrocytes/animal were scored for the presence of micronucleated immature erythrocytes, a sign of potential toxicity or damage to genetic material in the cells. Aureobasidium pullulans strain DSM 14941 did not produce a statistically significant increase in micronucleated immature erythrocytes compared to the untreated control animals. The response of the positive control animals (treated with a known toxic substance, cyclophosphamide, by intraperitoneal injection, at 10 mg/kg) was appropriate for comparison and did produce a statistically significant increase in micronucleated immature erythrocytes compared to the untreated control animals. This study was rated acceptable. 10. Influence of Temperature on Reproduction (MRID 47871833). Aureobasidium pullulans strain CBS 626.85 was isolated from the peritoneal dialysis fluid of a human in Australia. The effects of temperature on the reproduction or growth of Aureobasidium pullulans strains DSM 14940 and, DSM 14941, in liquid culture or on agar plates were examined and compared against this positive control, Aureobasidium pullulans strain CBS 626.85, to observe the ability of these strains to reproduce at human body temperature of 37 °C. All three strains grew well at 30 °C. At 33 °C, the number of replications (per 48 hours) of the Aureobasidium pullulans strains DSM 14940 and, DSM 14941 was less than one, while the number of PO 00000 Frm 00018 Fmt 4700 Sfmt 4700 duplications for strain CBS 626.85 was approximately five. Neither strain DSM 14940 or strain DSM 14941 was able to grow at 35 °C or 37 °C, while strain CBS 625.85 replicated (approximately) twice at 35 °C and once at 37 °C. Based on the lack of growth of the DSM strains at 35 °C and above, and given human body temperature is 37 °C, Aureobasidium pullulan strains DSM 14940 and DSM 14941 are expected to be nonpathogenic in humans. This study was rated acceptable. 11. Hypersensitivity Incidents (OCSPP Guideline 885.3400; MRID No. 47945023). No hypersensitivity incidents, including immediate-type or delayed-type reactions of humans and domestic animals during research, development, or testing of Aureobasidium pullulans strains DSM 14940 and DSM 14941 were reported by the applicant. Any future hypersensitivity incidents must be reported per OCSPP Guideline 885.3400. IV. Aggregate Exposures In examining aggregate exposure, section 408 of FFDCA directs EPA to consider available information concerning exposures from the pesticide residue in food and all other nonoccupational exposures, including drinking water from ground water or surface water and exposure through pesticide use in gardens, lawns, or buildings (residential and other indoor uses). A. Dietary Exposure Should this microbial pesticide be present on food, the acute toxicity, infectivity, and pathogenicity data, as well as the data demonstrating the lack of growth at human body temperature submitted for Aureobasidium pullulans strains DSM 14940 and DSM 14941 demonstrated that no toxicity, infectivity, and/or pathogenicity is likely to occur with any exposure level resulting from application of these two proposed pesticide active ingredients in accordance with good agricultural practices (see Unit III.B.). 1. Food. Naturally occurring Aureobasidium pullulans is likely to be present on fresh produce. According to Webb and Mundt (1978) (Ref. 11) Aureobasidium pullulans is ‘‘a major resident on most green plants.’’ In a study with several species of crop plants, they determined Aureobasidium pullulans to be among the most abundant (71%–85%) of all fungi present on the plant surfaces. Aureobasidium pullulans made up an average of 77.1% of the mold species isolated on green beans, and occurred at E:\FR\FM\15FER1.SGM 15FER1 Federal Register / Vol. 77, No. 31 / Wednesday, February 15, 2012 / Rules and Regulations erowe on DSK2VPTVN1PROD with RULES high levels (up to 2.7 × 104 cfu/ centimeter2 (cm2) on certain fruits (cucumbers and squash). Dietary exposure to Aureobasidium pullulans strains DSM 14940 and DSM 14941, therefore, is possible from strawberries, grapes, pome and stone fruits harvested naturally and from plants treated with these fungicidal active ingredients. The submitted acute oral toxicity/ pathogenicity studies indicated that if Aureobasidium pullulans strains DSM 14940 and DSM 14941 are ingested, no toxic or pathogenic effects will result. In addition, Aureobasidium pullulans strains DSM 14940 and DSM 14941 do not reproduce at the normal human body temperature of 37 °C. Therefore, in the event oral exposure should occur by ingesting treated fruits, the Agency concludes that there is a reasonable certainty that no harm will result from exposure to such residues. 2. Drinking water exposure. Naturally occurring Aureobasidium pullulans is ubiquitous and has been isolated from all types of water (Ref. 14). Exposure of humans to residues of pesticides containing Aureobasidium pullulans strains DSM 14940 and DSM 14941 in consumed drinking water is possible but potential exposure through drinking water is reduced, given the proposed use patterns, use sites, and application methods for Aureobasidium pullulans strains DSM 14940 and DSM 14941, which do not include direct application to aquatic environments. In the event that Aureobasidium pullulans strains DSM 14940 and DSM 14941 are transferred to surface water or ground water intended for human consumption, the fungi would not survive the high temperatures, chlorination, pH adjustments, and/or filtration water is subjected to in a drinking water treatment facility. Even if oral exposure should occur through consumed drinking water, there is a reasonable certainty that no harm will result from exposure to such residues, based upon the lack of toxicity, infectivity, and/or pathogenicity, as well as the inability of these fungal strains to grow at human body temperature, demonstrated in the previously described toxicological studies (see Unit III.B.). B. Other Non-Occupational Exposure The use sites for these products include residential garden sites and agricultural sites. Aureobasidium pullulans is naturally present in many habitats, and based on the data and other information submitted to satisfy data requirements for registration of the MPs and EPs containing the active ingredients Aureobasidium pullulans strains DSM 14940 and DSM 14941, no VerDate Mar<15>2010 14:28 Feb 14, 2012 Jkt 226001 toxicity, infectivity, pathogenicity or other adverse effects from nonoccupational exposure are expected (see Unit III.B.). V. 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.’’ The likelihood of adverse cumulative effects occurring via a common mechanism of toxicity is minimal, based on the lack of toxicity/pathogenicity/ infectivity potential of the active ingredients when Aureobasidium pullulans strains DSM 14940 and DSM 14941 are used in or on food commodities and/or labeled for residential uses (see Unit III.B.). In addition, Aureobasidium pullulans strains DSM 14940 and DSM 14941 do not appear to produce a toxic metabolite produced by other substances. For information regarding EPA’s efforts to determine which chemicals have a common mechanism of toxicity and to evaluate the cumulative effects of such chemicals, see EPA’s Web site at https://www.epa.gov/pesticides/ cumulative. VI. Determination of Safety for U.S. Population, Infants and Children FFDCA section 408(b)(2)(C) provides that EPA shall assess the available information about consumption patterns among infants and children, special susceptibility of infants and children to pesticide chemical residues, and the cumulative effects on infants and children of the residues and other substances with a common mechanism of toxicity. In addition, FFDCA section 408(b)(2)(C) 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 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. 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. Based on the acute toxicity and pathogenicity data summarized in Unit PO 00000 Frm 00019 Fmt 4700 Sfmt 4700 8735 III.B., EPA concludes that there is a reasonable certainty that no harm will result to the U.S. population, including infants and children, from aggregate exposure to the residues of Aureobasidium pullulans strains DSM 14940 and DSM 14941. This includes all anticipated dietary exposures and all other exposures for which there is reliable information. EPA has arrived at this conclusion because the data and information available on Aureobasidium pullulans strains DSM 14940 and DSM 14941 do not demonstrate toxic, pathogenic, and/or infective potential to mammals. Thus, there are no threshold effects of concern and, as a result, the Agency has concluded that an additional margin of safety for infants and children is unnecessary in this instance. Further, the need to consider consumption patterns, special susceptibility, and cumulative effects does not arise when dealing with pesticides with no demonstrated significant adverse effects. VII. Other Considerations A. Analytical Enforcement Methodology An analytical method is not required for enforcement purposes since the Agency is establishing an exemption from the requirement of a tolerance without any numerical limitation. 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 U.N. Food and Agriculture Organization/ World Health Organization food standards program, and it is recognized as an international food safety standards-setting organization in trade agreements to which the United States is a party. EPA may establish a tolerance that is different from a Codex MRL; however, FFDCA section 408(b)(4) requires that EPA explain the reasons for departing from the Codex level. The Codex has not established a MRL for Aureobasidium pullulans strains DSM 14940 or DSM 14941. VIII. Conclusions EPA concludes that there is a reasonable certainty that no harm will result to the United States population, including infants and children, from aggregate exposure to residues of E:\FR\FM\15FER1.SGM 15FER1 8736 Federal Register / Vol. 77, No. 31 / Wednesday, February 15, 2012 / Rules and Regulations Aureobasidium pullulans strains DSM 14940 and DSM 14941. Therefore, an exemption from the requirement of a tolerance is established for residues of Aureobasidium pullulans strains DSM 14940 and DSM 14941 in or on all food commodities when applied as a preharvest fungicide and used in accordance with good agricultural practices. IX. 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 final rule has been exempted from review under Executive Order 12866, this final rule is not subject to Executive Order 13211, entitled Actions Concerning Regulations That Significantly Affect Energy Supply, Distribution, or Use (66 FR 28355, May 22, 2001) or Executive Order 13045, entitled Protection of Children from Environmental Health Risks and Safety Risks (62 FR 19885, April 23, 1997). This final rule does not contain any information collections subject to OMB approval under the Paperwork Reduction Act (PRA), 44 U.S.C. 3501 et seq., nor does it require any special considerations under Executive Order 12898, entitled Federal Actions to Address Environmental Justice in Minority Populations and Low-Income Populations (59 FR 7629, February 16, 1994). Since tolerances and exemptions that are established on the basis of a petition under 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. erowe on DSK2VPTVN1PROD with RULES X.

II. Background and Statutory Findings

In the Federal Register of March 10, 2010 (75 FR 11171) (FRL-8810-
8), EPA issued a notice pursuant to section 408(d)(3) of FFDCA, 21
U.S.C. 346a(d)(3), announcing the filing of a pesticide tolerance
petition (PP 9F7623) by Bio-ferm GmbH, Konrad Lorenz Str. 20, Tulln,
3430, Austria. The petition requested that 40 CFR part 180 be amended
by establishing an exemption from the requirement of a tolerance for
residues of Aureobasidium pullulans strains DSM 14940 and DSM 14941.
This notice referenced a summary of the petition prepared by the
petitioner Bio-ferm GmbH, which is available in the docket, https://www.regulations.gov. There were no comments received in response to the
notice of filing.
Section 408(c)(2)(A)(i) of FFDCA allows EPA to establish an
exemption from the requirement for a tolerance (the legal limit for a
pesticide chemical residue in or on a food) only if EPA determines that
the exemption is ``safe.'' Section 408(c)(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. Pursuant to section 408(c)(2)(B) of FFDCA, in
establishing or maintaining in effect an exemption from the requirement
of a tolerance, EPA must take into account the factors set forth in
section 408(b)(2)(C) of FFDCA, which require 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. * *
*'' Additionally, section 408(b)(2)(D) of FFDCA requires that 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 performs a number of analyses to determine the risks from
aggregate exposure to pesticide residues. First, EPA determines the
toxicity of pesticides. Second, EPA examines exposure to the pesticide
through food, drinking water, and through other exposures that occur as
a result of pesticide use in residential settings.

III. Toxicological Profile

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 and considered its validity, completeness, and reliability
and the relationship of this information 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.

A. Overview of Aureobasidium Pullulans Strains DSM 14940 and DSM 14941

Aureobasidium pullulans is a ``yeast-like'' saprophytic fungus
found in the phyllosphere of many plants, and it has been isolated from
soil and aquatic environments (Refs. 1, 2, and 3). It is commonly
isolated from healthy grape (Refs. 4 and 5) and apple (Ref. 6) plants,
as well as other plants (Refs. 7, 8, 9, 10, and 11). Although
associated with disease in some plants, the fungus generally is
recognized as a saprobe, since it derives its nourishment from
nonliving or decaying organic matter, and is only considered a weak
pathogen or parasite of certain plants (Refs. 2 and 12). It is a known
antagonist of several plant disease-causing organisms, and is an
important producer of enzymes for biotechnological and industrial
applications (Ref. 1).
Aureobasidium pullulans strains DSM 14940 and DSM 14941 were
isolated from apple leaves and classified by the German Strain
Collection for Microorganisms (DSMZ). Neither is a

[[Page 8733]]

mutant nor genetically modified strain and they are not closely related
to toxigenic human pathogens. As discussed in Pesticide Petition (PP)
9F7623, product analysis data demonstrate that Aureobasidium pullulans
strain DSM 14941 is closely related to strain DSM 14940. The two
strains share many similar genetic and morphological characteristics.
Bioferm GmbH has proposed to register two manufacturing-use pesticide
products (MPs): ``Aureobasidium pullulans strain DSM 14941 Technical,''
and ``Aureobasidium pullulans strain DSM 14940 Technical.'' The active
ingredient is 80% w/w (minimum of x 10\9\ colony forming units/grams
(unit of measure for bacteria (cfu/g)) in each of the proposed
technical products.
Bio-ferm GmbH has proposed to register two end-use products (EPs)
containing equal parts of Aureobasidium pullulans strains DSM 14940 and
DSM 14941: ``Blossom Protect'' will be applied to pome fruit only
during the blossoming period to protect plants against bacterial fire
blight, and ``Botector'' will be applied preharvest to grapes, pome
fruit, stone fruit, and strawberries to protect these crops against
fruit rot diseases caused by Botrytis sp., Monilia sp., Penicillium
sp., Nectria sp., and Pezicula sp.

B. Microbial Pesticide Toxicology Data Requirements

The Agency has determined that, for preharvest uses, all mammalian
toxicology data requirements submitted to support the petition to
exempt residues of Aureobasidium pullulans strains DSM 14940 and DSM
14941 from the requirement of a tolerance have been fulfilled (Ref.
13).
The product analysis data demonstrated that Aureobasidium pullulans
strain DSM 14941 is closely related to strain DSM 14940. Because the
strains are closely related, the Agency has determined that the
findings of the submitted acute toxicity/pathogenicity studies
conducted only with strain DSM 14941 supported both strains, and those
studies show no evidence of toxicity, or pathogenicity at the doses
tested. In addition, both strains were tested in an acute subcutaneous
injection toxicity/pathogenicity study in rats. The results of this
study indicated that both strains were not toxic, infective, and/or
pathogenic to the test animals. These findings were supported by the
results of a study of the influence of temperature on the growth of the
two Aureobasidium pullulans strains, which showed that growth of both
strains does not occur at or above 35 [deg]C. Since human body
temperature is 37 [deg]C, and based on the results from these studies
as discussed in this unit the Agency concluded that neither strain
would be toxic, infective and/or pathogenic in humans.
1. Acute Oral Toxicity/Pathogenicity (Office of Chemical Safety and
Pollution Prevention (OCSPP) Guideline 885.3050; Master Record
Identification Number (MRID) No. 47899302. Twenty-four rats were
administered a single dose of Aureobasidium pullulans strain DSM 14941.
Three animals of each sex were sacrificed on days 3, 7, and 14; the
remaining animals were sacrificed at test end on day 21. Body tissues
were examined for Aureobasidium pullulans. All samples of feces, blood,
brain, lung, liver, kidney, spleen, stomach, and intestine were
negative. The lymph nodes of one animal sacrificed on day 7 tested
positive for the presence of Aureobasidium pullulans DSM 14941. These
findings show a pattern of clearance with no Aureobasidium pullulans
DSM 14941 detected by day 14. The results of this acceptable study
demonstrated that Aureobasidium pullulans DSM 14941 was not toxic,
infective, and/or pathogenic in rats, when dosed at 4 x 10\8\ cfu/
animal.
2. Acute Pulmonary Toxicity/Pathogenicity (OCSPP Guideline
885.3150; MRID No. 47899303). Male and female animals were exposed
intratracheally with Aureobasidium pullulans strain DSM 14941 Technical
(4 x 10\8\ cfu/g). Interim sacrifices were made 3 hours post-dose and
on study days 3, 7, and 14; the remaining animals were sacrificed at
study end on day 21. There was no mortality, and, except on the day of
dosing when the entire test material group showed reduced motor
activity and dyspnea, all animals appeared normal throughout the study.
Tissue samples were evaluated for Aureobasidium pullulans after
sacrifice. The following tissues were negative for Aureobasidium
pullulans at all time points: Feces, brain, kidney, and intestine.
Blood samples were negative except for one male on day 0; lung samples
were negative except for two males and two females on day 0; liver
samples were negative except for three males on day 0; spleen samples
were negative except for two males on day 0; lymph node samples were
negative except for one animal on day 7, and stomach samples were
negative except for two males on day 0. These findings show a pattern
of clearance with no Aureobasidium pullulans DSM 14941 detected by day
14. The results of this acceptable study demonstrated that
Aureobasidium pullulans DSM 14941 was not toxic, infective, and/or
pathogenic in rat, when dosed at 0.8 x 10\8\ cfu/animal.
3. Acute Injection Toxicity/Pathogenicity (OCSPP Guideline
885.3200; MRID No. 47871807 and 47871808). In an acute subcutaneous
toxicity/pathogenicity study (MRID 47871807), male and female rats were
injected with Aureobasidium pullulans strain DSM 14940 (2.36 x 10\10\
cfu/g) and DSM 14941 (1.5 x 10\10\ cfu/g). Interim sacrifices were made
on days 3, 7, and 14; the remaining animals were sacrificed at test end
on day 21. There were no deaths, and all animals appeared normal
throughout the study except for edema or slight erythema at the
injection site. Samples of the following tissues were negative for
Aureobasidium pullulans at all time points: Feces, blood, brain, lung,
liver, kidney, spleen, stomach, and intestine. Lymph node samples were
negative except for one animal sacrificed on day 7. The study author
suggested this was likely a post-mortem transmission. A pattern of
clearance was observed in this study, with no Aureobasidium pullulans
DSM 14941 or 14940 detected by day 14. The results of this acceptable
study demonstrated that Aureobasidium pullulans strains DSMZ 14940 and
DSMZ 14941 were not toxic, infective, and/or pathogenic in rats, when
dosed at 1.95 x 10\7\ or 1.12 x 10\7\cfu/animal, respectively.
In a second acute subcutaneous toxicity/pathogenicity study (MRID
47871808), male and female rats were injected with Aureobasidium
pullulans strain DSM 14941 (1.1 x 10\9\ cfu/g). Interim sacrifices were
made on days 1 and 7; the remaining animals were sacrificed at test end
on day 21. There were no deaths, and all animals appeared normal
throughout the study except for severe edema or slight erythema at the
injection site. Samples of the following tissues were negative for
Aureobasidium pullulans at all time points: Brain, lung, spleen,
kidney, lymph nodes, blood and urine. The skin was positive for
Aureobasidium pullulans in three males and three females from the test
material group on day 1 and in two females of the same group on day 7.
The liver of one male from the test material group was positive on day
1. The cecum contents were positive in one male and one female from the
test material group on day 1 and in two females from the same group on
day 7. These findings show a pattern of clearance with no Aureobasidium
pullulans DSM 14941 detected by day 21. The results of this acceptable
study demonstrated that Aureobasidium pullulans DSM 14941 was not
toxic, infective, and/or

[[Page 8734]]

pathogenic in rats, when dosed at 1.6 x 10\7\ cfu/animal.
4. Acute Dermal Toxicity (OCSPP Guideline 870.1200; MRID 47869615).
In an acute dermal toxicity study, the shaved skin of 10 rats was dosed
with 2,000 milligram/kilogram (mg/kg) Blossom Protect (7 x 10\9\ cfu/g
each of strains DSM 14940 and DSM 14941) for 24 hours. One male
exhibited chromodacryorrhea from day 7 to day 14 and one female
exhibited chromodacryorrhea from day 1 to day 2 of the study, but this
was not considered to be toxicologically significant because this is a
normal but rare response and it did not result in mortality. All
animals appeared healthy at necropsy. The lethal dose
(LD50) was >2,000 mg/kg. This study was rated
acceptable, and the end use product (EP) is classified as toxicity
category IV.
5. Primary Dermal Irritation (OCSPP Guideline 870.2500; MRID
47869619). In a dermal irritation study, the shaved skin of 3 rabbits
was dosed with 0.5 g Blossom Protect (7 x 10\9\ cfu/g Aureobasidium
pullulans strain DSM 14940 and 7 x 10\9\ cfu/g Aureobasidium pullulans
strain DSM 14941) moistened with 1.0 milliliter (mL) deionized water
for 4 hours. All animals appeared normal throughout the study; thus,
Blossom Protect was considered to be non-irritating. This study was
rated acceptable, and the EP is classified as toxicity category IV.
6. Acute Oral Toxicity (OCSPP Guideline 870.1100; MRID No.
47869614. In an acute oral toxicity study, six animals received a
single 2,000 mg/kg body weight (bw) dose of Blossom Protect 22% (2 x
10\10\ cfu/g) Aureobasidium pullulans strain DSM 14940, 22% (2 x 10\10\
cfu/g) Aureobasidium pullulans strain DSM 14941, 25% sucrose, 6% water.
There was no mortality, and all animals appeared normal throughout the
study. The LD50 was >2,000 mg/kg. This study was rated
acceptable, and the EP is classified as toxicity category III.
7. Acute Inhalation Toxicity (OCSPP Guideline 870.1300; MRID
47869617). In an acute inhalation toxicity study, 10 animals were
exposed nose-only to a 10% suspension of Blossom Protect (7 x 10 \9\
cfu/g A. pullulans strain DSM 14940 and 7 x 10\9\ cfu/g A. pullulans
strain DSM 14941) at 5.17 milligrams per liter (mg/L). The Mass Medium
Aerodynamic Diameter (MMAD) was 4.2 [micro]m. There were no deaths and
all animals appeared healthy throughout the study. Necropsy was
unremarkable. The lethal concentration (LC50) was
>5.17 mg/L. This study was rated acceptable, and the EP is classified
as toxicity category IV.
8. Acute Eye Irritation (OCSPP Guideline 870.2400; MRID 47869618).
In an eye irritation study, three rabbits were dosed with 0.1 mL (60-62
grams (g) of Blossom Protect (7 x 10\9\ cfu/g A. pullulans strain DSM
14940 and 7 x 10\9\ cfu/g A. pullulans strain DSM 14941). One animal
had a score of 1 for conjunctival redness 1 hour after application.
There were no other clinical signs, and all animals appeared normal at
24 hours. Blossom protect was considered to be virtually non-
irritating. This study was rated acceptable, and the EP is classified
as toxicity category IV.
9. In vivo Micronucleus Assay (MRID 47899304). Twenty mice (two
groups of five male and two groups of five female mice) received single
2,000 mg/kg Aureobasidium pullulans strain DSM 14941 dissolved in water
by oral gavage. There were no clinical signs observed in any of the
test animals, which were sacrificed 24 or 48 hours after receiving the
test material. The femoral bone marrow was immediately harvested, and
the ratio of polychromatic erythrocytes to total erythrocytes (mature
and immature) was determined, and 2,000 immature erythrocytes/animal
were scored for the presence of micronucleated immature erythrocytes, a
sign of potential toxicity or damage to genetic material in the cells.
Aureobasidium pullulans strain DSM 14941 did not produce a
statistically significant increase in micronucleated immature
erythrocytes compared to the untreated control animals. The response of
the positive control animals (treated with a known toxic substance,
cyclophosphamide, by intraperitoneal injection, at 10 mg/kg) was
appropriate for comparison and did produce a statistically significant
increase in micronucleated immature erythrocytes compared to the
untreated control animals. This study was rated acceptable.
10. Influence of Temperature on Reproduction (MRID 47871833).
Aureobasidium pullulans strain CBS 626.85 was isolated from the
peritoneal dialysis fluid of a human in Australia. The effects of
temperature on the reproduction or growth of Aureobasidium pullulans
strains DSM 14940 and, DSM 14941, in liquid culture or on agar plates
were examined and compared against this positive control, Aureobasidium
pullulans strain CBS 626.85, to observe the ability of these strains to
reproduce at human body temperature of 37 [deg]C. All three strains
grew well at 30 [deg]C. At 33 [deg]C, the number of replications (per
48 hours) of the Aureobasidium pullulans strains DSM 14940 and, DSM
14941 was less than one, while the number of duplications for strain
CBS 626.85 was approximately five. Neither strain DSM 14940 or strain
DSM 14941 was able to grow at 35 [deg]C or 37 [deg]C, while strain CBS
625.85 replicated (approximately) twice at 35 [deg]C and once at 37
[deg]C. Based on the lack of growth of the DSM strains at 35 [deg]C and
above, and given human body temperature is 37 [deg]C, Aureobasidium
pullulan strains DSM 14940 and DSM 14941 are expected to be non-
pathogenic in humans. This study was rated acceptable.
11. Hypersensitivity Incidents (OCSPP Guideline 885.3400; MRID No.
47945023). No hypersensitivity incidents, including immediate-type or
delayed-type reactions of humans and domestic animals during research,
development, or testing of Aureobasidium pullulans strains DSM 14940
and DSM 14941 were reported by the applicant. Any future
hypersensitivity incidents must be reported per OCSPP Guideline
885.3400.

IV. Aggregate Exposures

In examining aggregate exposure, section 408 of FFDCA directs EPA
to consider available information concerning exposures from the
pesticide residue in food and all other non-occupational exposures,
including drinking water from ground water or surface water and
exposure through pesticide use in gardens, lawns, or buildings
(residential and other indoor uses).

A. Dietary Exposure

Should this microbial pesticide be present on food, the acute
toxicity, infectivity, and pathogenicity data, as well as the data
demonstrating the lack of growth at human body temperature submitted
for Aureobasidium pullulans strains DSM 14940 and DSM 14941
demonstrated that no toxicity, infectivity, and/or pathogenicity is
likely to occur with any exposure level resulting from application of
these two proposed pesticide active ingredients in accordance with good
agricultural practices (see Unit III.B.).
1. Food. Naturally occurring Aureobasidium pullulans is likely to
be present on fresh produce. According to Webb and Mundt (1978) (Ref.
11) Aureobasidium pullulans is ``a major resident on most green
plants.'' In a study with several species of crop plants, they
determined Aureobasidium pullulans to be among the most abundant (71%-
85%) of all fungi present on the plant surfaces. Aureobasidium
pullulans made up an average of 77.1% of the mold species isolated on
green beans, and occurred at

[[Page 8735]]

high levels (up to 2.7 x 10\4\ cfu/centimeter\2\ (cm\2\) on certain
fruits (cucumbers and squash). Dietary exposure to Aureobasidium
pullulans strains DSM 14940 and DSM 14941, therefore, is possible from
strawberries, grapes, pome and stone fruits harvested naturally and
from plants treated with these fungicidal active ingredients. The
submitted acute oral toxicity/pathogenicity studies indicated that if
Aureobasidium pullulans strains DSM 14940 and DSM 14941 are ingested,
no toxic or pathogenic effects will result. In addition, Aureobasidium
pullulans strains DSM 14940 and DSM 14941 do not reproduce at the
normal human body temperature of 37 [deg]C. Therefore, in the event
oral exposure should occur by ingesting treated fruits, the Agency
concludes that there is a reasonable certainty that no harm will result
from exposure to such residues.
2. Drinking water exposure. Naturally occurring Aureobasidium
pullulans is ubiquitous and has been isolated from all types of water
(Ref. 14). Exposure of humans to residues of pesticides containing
Aureobasidium pullulans strains DSM 14940 and DSM 14941 in consumed
drinking water is possible but potential exposure through drinking
water is reduced, given the proposed use patterns, use sites, and
application methods for Aureobasidium pullulans strains DSM 14940 and
DSM 14941, which do not include direct application to aquatic
environments. In the event that Aureobasidium pullulans strains DSM
14940 and DSM 14941 are transferred to surface water or ground water
intended for human consumption, the fungi would not survive the high
temperatures, chlorination, pH adjustments, and/or filtration water is
subjected to in a drinking water treatment facility. Even if oral
exposure should occur through consumed drinking water, there is a
reasonable certainty that no harm will result from exposure to such
residues, based upon the lack of toxicity, infectivity, and/or
pathogenicity, as well as the inability of these fungal strains to grow
at human body temperature, demonstrated in the previously described
toxicological studies (see Unit III.B.).

B. Other Non-Occupational Exposure

The use sites for these products include residential garden sites
and agricultural sites. Aureobasidium pullulans is naturally present in
many habitats, and based on the data and other information submitted to
satisfy data requirements for registration of the MPs and EPs
containing the active ingredients Aureobasidium pullulans strains DSM
14940 and DSM 14941, no toxicity, infectivity, pathogenicity or other
adverse effects from non-occupational exposure are expected (see Unit
III.B.).

V. 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.''
The likelihood of adverse cumulative effects occurring via a common
mechanism of toxicity is minimal, based on the lack of toxicity/
pathogenicity/infectivity potential of the active ingredients when
Aureobasidium pullulans strains DSM 14940 and DSM 14941 are used in or
on food commodities and/or labeled for residential uses (see Unit
III.B.). In addition, Aureobasidium pullulans strains DSM 14940 and DSM
14941 do not appear to produce a toxic metabolite produced by other
substances. For information regarding EPA's efforts to determine which
chemicals have a common mechanism of toxicity and to evaluate the
cumulative effects of such chemicals, see EPA's Web site at https://www.epa.gov/pesticides/cumulative.

VI. Determination of Safety for U.S. Population, Infants and Children

FFDCA section 408(b)(2)(C) provides that EPA shall assess the
available information about consumption patterns among infants and
children, special susceptibility of infants and children to pesticide
chemical residues, and the cumulative effects on infants and children
of the residues and other substances with a common mechanism of
toxicity. In addition, FFDCA section 408(b)(2)(C) 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 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. 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.
Based on the acute toxicity and pathogenicity data summarized in
Unit III.B., EPA concludes that there is a reasonable certainty that no
harm will result to the U.S. population, including infants and
children, from aggregate exposure to the residues of Aureobasidium
pullulans strains DSM 14940 and DSM 14941. This includes all
anticipated dietary exposures and all other exposures for which there
is reliable information. EPA has arrived at this conclusion because the
data and information available on Aureobasidium pullulans strains DSM
14940 and DSM 14941 do not demonstrate toxic, pathogenic, and/or
infective potential to mammals. Thus, there are no threshold effects of
concern and, as a result, the Agency has concluded that an additional
margin of safety for infants and children is unnecessary in this
instance. Further, the need to consider consumption patterns, special
susceptibility, and cumulative effects does not arise when dealing with
pesticides with no demonstrated significant adverse effects.

VII. Other Considerations

A. Analytical Enforcement Methodology

An analytical method is not required for enforcement purposes since
the Agency is establishing an exemption from the requirement of a
tolerance without any numerical limitation.

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 U.N. Food and
Agriculture Organization/World Health Organization food standards
program, and it is recognized as an international food safety
standards-setting organization in trade agreements to which the United
States is a party. EPA may establish a tolerance that is different from
a Codex MRL; however, FFDCA section 408(b)(4) requires that EPA explain
the reasons for departing from the Codex level.
The Codex has not established a MRL for Aureobasidium pullulans
strains DSM 14940 or DSM 14941.

VIII. Conclusions

EPA concludes that there is a reasonable certainty that no harm
will result to the United States population, including infants and
children, from aggregate exposure to residues of

[[Page 8736]]

Aureobasidium pullulans strains DSM 14940 and DSM 14941. Therefore, an
exemption from the requirement of a tolerance is established for
residues of Aureobasidium pullulans strains DSM 14940 and DSM 14941 in
or on all food commodities when applied as a preharvest fungicide and
used in accordance with good agricultural practices.

IX. 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 final rule has been
exempted from review under Executive Order 12866, this final rule is
not subject to Executive Order 13211, entitled Actions Concerning
Regulations That Significantly Affect Energy Supply, Distribution, or
Use (66 FR 28355, May 22, 2001) or Executive Order 13045, entitled
Protection of Children from Environmental Health Risks and Safety Risks
(62 FR 19885, April 23, 1997). This final rule does not contain any
information collections subject to OMB approval under the Paperwork
Reduction Act (PRA), 44 U.S.C. 3501 et seq., nor does it require any
special considerations under Executive Order 12898, entitled Federal
Actions to Address Environmental Justice in Minority Populations and
Low-Income Populations (59 FR 7629, February 16, 1994).
Since tolerances and exemptions that are established on the basis
of a petition under 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.

XI. Congressional Review Act

The Congressional Review Act, 5 U.S.C. 801 et seq., generally
provides that before a rule may take effect, the agency promulgating
the rule must submit a rule report 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).
