Trichoderma virens strain G-41; Exemption From the Requirement of a Tolerance

AGENCY: Environmental Protection Agency (EPA).

ACTION: Final rule.

-----------------------------------------------------------------------

SUMMARY: This regulation establishes an exemption from the requirement of a tolerance for residues of Trichoderma virens strain G-41 in or on all food commodities when applied as a fungicide and used in accordance with good agricultural practices. BioWorks, Inc., submitted a petition to EPA under the Federal Food, Drug, and Cosmetic Act (FFDCA), requesting an exemption from the requirement of a tolerance. This regulation eliminates the need to establish a maximum permissible level for residues of Trichoderma virens strain G-41 under the FFDCA.

DATES: This regulation is effective February 1, 2012. Objections and requests for hearings must be received on or before April 2, 2012, and must be filed in accordance with the instructions provided in 40 CFR part 178 (see also Unit I.C. of the SUPPLEMENTARY INFORMATION).

  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 9F7618) by Technology Sciences Group, Inc., on behalf of BioWorks, Inc., 100 Rawson Rd., Suite 205, Victor, NY 14564. The petition requested that 40 CFR part 180 be amended by establishing an exemption from the requirement of a tolerance for residues of Trichoderma virens strain G-41. This notice referenced a summary of the petition prepared by the petitioner, BioWorks, Inc., which is available in the docket via http://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 exemption 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 EPA 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.

  3. 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.

    1. Overview of Trichoderma virens strain G-41

      Trichoderma species are common soil hyphomycetes found in all climate zones ranging from Antarctica to the tropics (Ref. 1). Since 1989, several Trichoderma species (e.g., Trichoderma polysporum, Trichoderma viride, and Trichoderma harzianum) have been used in pesticide products--notably without reported incidents--to control various fungal plant pathogens such as Pythium species, Phytophthora species, Heterobasidion annosum, and Chondrostereum purpureum. In conjunction with the registration of some of these pesticide products, EPA established the following exemptions from the requirement of a tolerance:

      1. Gliocladium virens strain GL-21 (now recognized as Trichoderma virens strain GL-21) (40 CFR 180.1100)--see the Federal Register of September 20, 1995 (60 FR 48657) (FRL-4974-1) and October 5, 1995 (60 FR 52248) (FRL-4974-1).

      2. Trichoderma harzianum Rifai strain T-22 (40 CFR 180.1102)--see the Federal Register of April 7, 1999 (64 FR 16856) (FRL-6070-3).

      3. Trichoderma harzianum strain T-39 (40 CFR 180.1201)--see the Federal Register of June 22, 2000 (65 FR 38753) (FRL-6383-7).

      4. Trichoderma gamsii strain ICC 080 (40 CFR 180.1293)--see the Federal Register of February 25, 2010 (75 FR 8504) (FRL-8799-4).

      5. Trichoderma asperellum strain ICC 012 (40 CFR 180.1294)--see the Federal Register of March 3, 2010 (75 FR 9527) (FRL-8800-9).

        Page 4905

      6. Trichoderma hamatum isolate 382 (40 CFR 180.1298)--see the Federal Register of July 23, 2010 (75 FR 43072) (FRL-8835-6).

        Specifically, Trichoderma virens, including strain G-41, is a naturally occurring fungus that is native to the United States and is widely distributed throughout the world, inhabiting forest, agricultural, and orchard soils, as well as plant litter (Ref. 2). Trichoderma virens strain G-41 was isolated from soil samples taken from Aphanomyces-suppressive fields in Livingston County, New York. Much like other Trichoderma species, Trichoderma virens strain G-41 inhibits or kills certain plant-pathogenic fungi (e.g., Rhizoctonia species and Fusarium species) through competition for food and space, mycoparasitism, antibiosis, and induction of plant defense responses (Refs. 1, 2, 3, and 4).

    2. Microbial Pesticide Toxicology Data Requirements

      All applicable mammalian toxicology data requirements supporting the request for an exemption from the requirement of a tolerance for residues of Trichoderma virens strain G-41 in or on all food commodities have been fulfilled with data submitted or cited by the petitioner.

      The petitioner conducted several acute toxicological tests with Trichoderma virens strain G-41 or a substance containing Trichoderma virens strain G-41. The acute oral toxicity/pathogenicity test evaluated the potential toxicity and pathogenicity of the active ingredient should dietary exposure occur. The acute dermal toxicity and primary dermal irritation tests evaluated the potential for a substance containing the active ingredient to cause toxicity or irritation should skin exposure occur. The acute inhalation toxicity test evaluated the potential for a substance containing the active ingredient to cause toxicity should inhalation exposure occur. The results of these studies revealed little to no toxicity or irritation attributed to Trichoderma virens strain G-41, and all these studies received a Toxicity Category IV classification (see 40 CFR 156.62). Moreover, when the skin was bypassed as a protective barrier during an acute injection toxicity/

      pathogenicity test, Trichoderma virens strain G-41 was not found to be toxic, infective, and/or pathogenic via the intraperitoneal route of exposure. Finally, the petitioner has reported that no hypersensitivity incidents occurred during development and testing of this fungus.

      With its petition, BioWorks, Inc., also cited to toxicological data done with a similar, previously registered strain of Trichoderma virens, GL-21 (Refs. 1, 3, 4, and 5). Although GL-21 and G-41 are not identical, the two strains share many characteristics typical of Trichoderma virens (e.g., particular morphological features, production of certain enzymes involved in mycoparasitism, and weak growth at the temperature of the human body (37degC)), and thus are considered to be functionally similar (Ref. 4). Based on these similarities, EPA concluded that data on Trichoderma virens strain GL-21 would be representative of the toxicological nature of Trichoderma virens strain G-41 (Ref. 6). These additional data on Trichoderma virens strain GL-21 confirmed (i.e., no toxicity observed) and contributed (i.e., no pathogenicity anticipated) to the findings of the acute oral toxicity/

      pathogenicity study mentioned above and fulfilled the acute pulmonary toxicity/pathogenicity data requirement for Trichoderma virens strain G-41.

      The overall conclusions from all toxicological information submitted and cited by the petitioner are briefly described below, while more in-depth synopses of some study results can be found in the associated Biopesticides Registration Action Document provided as a reference in Unit IX. (Ref. 5).

      1. Acute oral toxicity/pathogenicity--rat (Harmonized Guideline 885.3050; Master Record Identification Numbers (MRID Nos.) 483438-01 and 407198-04). The petitioner submitted or cited to data resulting from two separate acute oral toxicity/pathogenicity tests, one conducted with Trichoderma virens strain G-41 and the other conducted with Trichoderma virens strain GL-21. The results of the first study demonstrated that Trichoderma virens strain G-41 was not toxic to rats when administered by oral gavage in a single dose of 1.5 x 10\8\ colony-forming units (cfu)/animal. Although a pattern of clearance was established, the sensitivity of detection indicated low recovery of Trichoderma virens strain G-41 from tissues and fluids (i.e., 0.5-9%). Thus, pathogenicity was not unequivocally assessed. The second study demonstrated that Trichoderma virens strain GL-21, a strain that is functionally similar to Trichoderma virens strain G-41, was not toxic to, infective in, or pathogenic for rats when given a single oral dose of 10\8\ cfu/animal and adequately addressed the pathogenicity endpoint that could not be fully assessed in the first study. The weight-of-

        evidence from the results of these two studies indicates that Trichoderma virens strain G-41 is not acutely toxic and/or pathogenic through the oral route of exposure.

      2. Acute pulmonary toxicity/pathogenicity--rat (Harmonized Guideline 885.3150; MRID Nos. 407198-05 and 408640-02). An acute pulmonary toxicity/pathogenicity study demonstrated that Trichoderma virens strain GL-21, a functionally similar strain to Trichoderma virens strain G-41, was not toxic to, infective in, or pathogenic for rats when given a single intratracheal dose of 10\8\ cfu/animal. Given the functional similarity of these two strains, EPA concludes that Trichoderma virens strain G-41 is also not likely to be toxic, infective, and/or pathogenic through the inhalation route. To further support this conclusion, an acceptable acute inhalation toxicity study (MRID No. 478650-04) resulted in no mortalities and only minor signs of toxicity (activity decrease; piloerection) that resolved by day 2 after rats were exposed to a test substance containing Trichoderma virens strain G-41 at 5.14 milligrams per liter for 4 hours.

      3. Acute injection toxicity/pathogenicity (intraperitoneal)--rat (Harmonized Guideline 885.3200; MRID Nos. 478651-02 and 482368-01). An acceptable acute injection toxicity/pathogenicity study demonstrated that Trichoderma virens strain G-41 was not toxic to rats when administered intraperitoneally in a single dose of 10\7\ cfu/animal. While clearance was not directly assessed in this study, the lack of clinical findings upon necropsy, in combination with the lack of signs of toxicity and mortality in the animals during the observation period, strongly suggests that Trichoderma virens strain G-41 is also not pathogenic by intraperitoneal injection.

      4. Hypersensitivity incidents (Harmonized Guideline 885.3400; MRID No. 482526-01). The petitioner reported that no hypersensitivity incidents, including immediate-type or delayed-type reactions of humans and domestic animals, occurred during research, development, or testing of Trichoderma virens strain G-41.

      5. Acute dermal toxicity--rat (Harmonized Guideline 870.1200; MRID No. 478650-03). An acceptable acute dermal toxicity study demonstrated that a test substance containing Trichoderma virens strain G-41 was not toxic to rats when dosed at 5,050 milligrams per kilogram (mg/kg) for 24 hours. The dermal median lethal dose (LD50), which is a statistically derived single dose that can be expected to cause death in 50% of test animals, was greater than 5,050 mg/kg for male and female rats combined (Toxicity Category IV).

        Page 4906

      6. Primary dermal irritation--rabbit (Harmonized Guideline 870.2500; MRID No. 478650-06). An acceptable primary dermal irritation study demonstrated that a test substance containing Trichoderma virens strain G-41 was non-irritating to the skin of rabbits (Toxicity Category IV).

  4. Aggregate Exposure

    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).

    1. Dietary Exposure

      1. Food exposure. All proposed Trichoderma virens strain G-41 applications are soil directed or soil incorporated because of the targeted soilborne pests (e.g., Rhizoctonia species and Fusarium species). Based on calculations made in EPA's environmental risk assessment for Trichoderma virens strain G-41 (Ref. 7), these applications are not expected to significantly increase the populations of this fungus above natural levels in the soil. No reports were available in the literature describing natural concentrations of Trichoderma virens; however, Trichoderma species have been reported in various types of soils at concentrations of 10\4\ to 10\6\ colony-

        forming units per gram (cfu/g) (Refs. 8 and 9). Based on the maximum application rate of the proposed end-use pesticide products containing Trichoderma virens strain G-41, the estimated amount of Trichoderma virens applied to the soil surface is approximately 6.7 x 10\3\ colony-

        forming units per square centimeter (cfu/cm\2\). Assuming a bulk density of 1 to 2 grams per cubic centimeter (g/cm\3\), the maximum application rate will not result in soil concentrations that are substantially greater than concentrations of Trichoderma virens naturally found in the soil, and overall increased exposure to Trichoderma virens in the terrestrial environment, including on above-

        ground plant parts such as food commodities, is not expected. Work by Jackson et al. (1991) supports this conclusion given that, after Trichoderma virens and three other Trichoderma isolates were incorporated into soil, fungal numbers either transiently increased, remained stable, or declined (Ref. 10). Should this microbial pesticide be present on food, the acute oral toxicity and pathogenicity data available for Trichoderma virens strain G-41 and functionally similar Trichoderma virens strain GL-21 demonstrated that no toxicity, infectivity, and/or pathogenicity is likely to occur with any exposure level of Trichoderma virens strain G-41 resulting from application in accordance with good agricultural practices (see additional discussion in Unit III.B.).

      2. Drinking water exposure. Exposure to residues of Trichoderma virens strain G-41 in consumed drinking water is unlikely. The proposed use patterns for Trichoderma virens strain G-41 are soil directed and soil incorporated, thereby limiting contact with surface water by drift and runoff. Furthermore, ground water is not expected to have significant exposure to Trichoderma virens strain G-41 since, like other Trichoderma species, this fungus would likely be filtered out by the particulate nature of many soil types, and be concentrated in upper soil horizons (Refs. 11 and 12) near plant roots (Ref. 13). If Trichoderma virens strain G-41 were to be transferred to surface or ground waters (e.g., through spray drift or runoff) that are intended for eventual human consumption and directed to wastewater treatment systems or drinking water facilities, it likely would not survive the conditions water is subjected to in such systems or facilities, including chlorination, pH adjustments, filtration, and occasionally high temperatures (Refs. 14 and 15). For instance, Trichoderma virens strain G-41 does not grow well at 37 degC (Refs. 3 and 16), and test data has shown it to be unstable at elevated temperatures; therefore, any heat treatment applied to water containing Trichoderma virens strain G-41 would probably render the fungus non-viable. In the remote likelihood that this microbial pesticide is present in drinking water (e.g., water not subject to treatment systems or facilities), the acute oral toxicity and pathogenicity data available for Trichoderma virens strain G-41 and functionally similar Trichoderma virens strain GL-21 demonstrated no toxicity, infectivity, and/or pathogenicity is likely to occur with any exposure level of Trichoderma virens strain G-41 resulting from application in accordance with good agricultural practices (see additional discussion in Unit III.B.).

    2. Other Non-Occupational Exposure

      Given Trichoderma virens' natural occurrence in soil (Ref. 2), non-

      occupational exposure to the fungus is likely already occurring. Even with the proposed pesticide applications of Trichoderma virens strain G-41, it is not likely that there will be a significant increase in these exposures due to the relative stability of typical background levels in the soil (see calculations and information presented in the food exposure section above). If significant non-occupational exposures were to occur, such exposures would not exceed EPA's level of concern in light of test results that indicated Trichoderma virens strain G-41 is not toxic (acute pulmonary toxicity/pathogenicity, acute dermal toxicity, and acute inhalation toxicity), is non-irritating (primary dermal irritation), and is not pathogenic or infective (acute pulmonary toxicity/pathogenicity) (see additional discussion in Unit III.B.).

  5. 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 exemption, EPA consider ``available information concerning the cumulative effects of a particular pesticide's * * * residues and other substances that have a common mechanism of toxicity.''

    There are several Trichoderma species used as active ingredients in registered pesticide products. While these different microbial pest control agents may produce similar metabolites, the likelihood of adverse cumulative effects via a common mechanism of toxicity is not anticipated, based on the lack of toxicity/pathogenicity potential of the active ingredients used on food and/or labeled for residential uses (see Unit III.B., as well as Refs. 17, 18, 19, and 20). For information regarding EPA's efforts to determine which chemicals have a common mechanism of toxicity and to evaluate the cumulative effects of such chemicals, see EPA's Web site at http://www.epa.gov/pesticides/cumulative.

  6. Determination of Safety for United States Population, Infants and Children

    FFDCA section 408(b)(2)(C) provides that, in considering the establishment of a tolerance or tolerance exemption for a pesticide chemical residue, 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

    Page 4907

    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 Food Quality Protection Act 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/information discussed in Unit III.B., as well as use of Trichoderma pesticide products since 1989 without reported adverse effects to humans, EPA concludes that there are no threshold effects of concern to infants, children, or adults when Trichoderma virens strain G-41 is used as labeled in accordance with good agricultural practices. As a result, EPA concludes that no additional margin of exposure (safety) is necessary to protect infants and children and that not adding any additional margin of exposure (safety) will be safe for infants and children.

    Moreover, based on the same data and EPA analysis as presented directly above, the Agency is able to conclude 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 Trichoderma virens strain G-41 when it is used as labeled and in accordance with good agricultural practices as a fungicide. Such exposure includes all anticipated dietary exposures and all other exposures for which there is reliable information. EPA has arrived at this conclusion because, considered collectively, the data and information available on Trichoderma virens strain G-41, as well as data available on functionally similar Trichoderma virens strain GL-21, do not demonstrate toxic, pathogenic, and/or infective potential to mammals, including infants and children.

  7. Other Considerations

    1. Analytical Enforcement Methodology

      An analytical method is not required for enforcement purposes for the reasons stated above and because EPA is establishing an exemption from the requirement of a tolerance without any numerical limitation.

    2. 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. In this context, EPA considers the international maximum residue limits (MRLs) established by the Codex Alimentarius Commission (Codex), as required by FFDCA section 408(b)(4). The Codex Alimentarius is a joint United Nations Food and Agriculture Organization/World Health Organization food standards program, and it is recognized as an international food safety standards-setting organization in trade agreements to which the United States is a party. EPA may establish a tolerance that is different from a Codex MRL; however, FFDCA section 408(b)(4) requires that EPA explain the reasons for departing from the Codex level.

      The Codex has not established a MRL for Trichoderma virens strain G-41.

  8. Conclusions

    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 residues of Trichoderma virens strain G-41. Therefore, an exemption from the requirement of a tolerance is established for residues of Trichoderma virens strain G-41 in or on all food commodities when applied as a fungicide and used in accordance with good agricultural practices.

  10. Statutory and Executive Order Reviews

    This final rule establishes a tolerance exemption under section 408(d) of FFDCA in response to a petition submitted to EPA. 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 exemption in this final rule, do not require the issuance of a proposed rule, the requirements of the Regulatory Flexibility Act (RFA) (5 U.S.C. 601 et seq.) do not apply.

    This final rule directly regulates growers, food processors, food handlers, and food retailers, not States or tribes. As a result, this action does not alter the relationships or distribution of power and responsibilities established by Congress in the preemption provisions of section 408(n)(4) of FFDCA. As such, EPA has determined that this action will not have a substantial direct effect on States or tribal governments, on the relationship between the national government and the States or tribal governments, or on the distribution of power and responsibilities among the various levels of government or between the Federal Government and Indian tribes. Thus, EPA has determined that Executive Order 13132, entitled Federalism (64 FR 43255, August 10, 1999), and Executive Order 13175, entitled Consultation and Coordination with Indian Tribal Governments (65 FR 67249, November 9, 2000), do not apply to this final rule. In addition, this final rule does not impose any enforceable duty or contain any unfunded mandate as described under Title II of the Unfunded Mandates Reform Act of 1995 (UMRA) (Pub. L. 104-4).

    This action does not involve any technical standards that would require EPA 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).

  11. 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 United States Senate, the United States 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).
