Bacillus Pumilus Strain GHA 180; Exemption From the Requirement of a Tolerance
This regulation establishes an exemption from the requirement of a tolerance for residues of Bacillus pumilus strain GHA 180 in or on all food commodities when used in accordance with good agricultural practices. Premier Horticulture 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 Bacillus pumilus strain GHA 180.

II. Background and Statutory Findings Back to Top
In the Federal Register of September 30, 2010 (75 FR 60452) (FRL-8837-2), EPA issued a notice pursuant to FFDCA section 408(d)(3), 21 U.S.C. 346a(d)(3), announcing the filing of a pesticide tolerance petition (PP 0F7698) by Premier Horticulture, 1, Avenue Premier, Riviere-du-Loup, Quebec, Canada. The petition requested that 40 CFR part 180 be amended by establishing an exemption from the requirement of a tolerance for residues of Bacillus pumilus GHA 180. This notice referenced a summary of the petition prepared by the petitioner Premier Horticulture, 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 FFDCA section 408(c)(2)(B), in establishing or maintaining in effect an exemption from the requirement of a tolerance, EPA must take into account the factors set forth in FFDCA section 408(b)(2)(C), 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, FFDCA section 408(b)(2)(D) 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 Back to Top
Consistent with FFDCA section 408(b)(2)(D), 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.
Bacillus pumilus strain GHA 180 is a bacterium discovered in the root zone of apple trees in Mexico. It colonizes plant roots and produces metabolites that suppress the fungal plant pathogens Pythium ultimum, Fusarium oxysporum, Rhizoctonia solani and Alternaria spp.
Adequate mammalian toxicology data and information were submitted to support Bacillus pumilus strain GHA 180 pesticide products. The Draft Biopesticide Registration Action Document (BRAD) for Bacillus pumilus strain GHA 180 provides detailed information regarding these tests (Ref. 1), which are summarized in this unit.
1. Acute Injection Toxicity/Pathogenicity (OCSPP Guideline 885.3200; Master Record Identification Number (MRID) No. 48005025): Bacillus pumilus GHA 180 was not toxic and/or pathogenic to laboratory rats given a single intravenous dose of 6.8 × 10  colony forming units (CFU).
2. Acute Oral Toxicity (OCSPP Guideline 870.1100; MRID No. 48005020): Bacillus pumilus GHA 180 was not toxic to rats given a single oral dose by gavage [median lethal dose (LD 50) >5,000 milligrams/kilograms (mg/kg) body weight (bw), Toxicity Category IV].
3. Acute Dermal Toxicity (OCSPP Guideline 870.1200; MRID 48005021): Bacillus pumilus GHA180 was not toxic to rats when applied to the skin (LD 50>5050 mg/kg bw, Toxicity Category IV).
4. Acute Inhalation Toxicity (OCSPP Guideline 870.1300; MRID 48005022): No signs of toxicity or other adverse effects occurred in rats exposed nose-only to an aerosol containing Bacillus pumilus GHA 180 Technical Grade of the Active Ingredient (TGAI) (2.18 mg/L) for 4 hours (LC 50>2.18 mg/L, EPA Toxicity Category IV).
5. Acute Eye Irritation (OCSPP Guideline 870.2400; MRID 48005023): Bacillus pumilus GHA 180 was mildly irritating to the eyes of rabbits (Toxicity Category III).
6. Primary Dermal Irritation (OCSPP Guideline 870.2500; MRID 48005024): Bacillus pumilus GHA 180 TGAI was nonirritating to the skin of rabbits (Toxicity Category IV).
IV. Aggregate Exposures Back to Top
In examining aggregate exposure, FFDCA section 408 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
1. Food. Bacillus species, including Bacillus pumilus, are common in soils (Ref. 2). Dried food, such as spices, milk powder and grains, often contain large amounts of Bacillus spores (Ref. 3), and Bacillus pumilus is a natural component of fermented fish sauce and cocoa bean fermentations (Ref. 4). Bacillus pumilus strain GHA 180 is not known to produce mammalian toxins, and no foodborne disease outbreaks have been reported. Based on the results of toxicity studies conducted with Bacillus pumilus strain GHA 180 TGAI, no toxicity, infectivity, pathogenicity or other adverse effects from dietary exposure to this bacterium from its pesticide uses are expected (see Unit III.).
2. Drinking water exposure. According to the World Health Organization, Bacillus species are often detected in drinking water even after going through disinfection processes at water treatment facilities (Ref. 5). If residues of Bacillus pumilus GHA 180 occur in drinking water from its pesticide uses, no adverse effects are expected based on the results of toxicity studies described in Unit III.
B. Other Non-Occupational Exposure
Pesticide products with the active ingredient Bacillus pumilus strain GHA 180 are only used in greenhouses and contained nurseries. Non-occupational exposures may occur in populations that access residential greenhouses and apply these pesticide products or handle soils that have been treated with Bacillus pumilus GHA 180. The personal protective equipment indicated on the label are expected to be adequate to minimize human exposure to those handling pesticide products containing Bacillus pumilus GHA 180. Should human exposure occur, however, no adverse effects are expected based on the lack of toxicity, infectivity and pathogenicity in the studies described in Unit III.
V. Cumulative Effects From Substances With a Common Mechanism of Toxicity Back to Top
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.”
EPA has not found Bacillus pumilus strain GHA 180 to share a common mechanism of toxicity with any other substances, and Bacillus pumilus strain GHA 180 does not appear to produce a toxic metabolite produced by other substances. For the purposes of this tolerance action, therefore, EPA has assumed that Bacillus pumilus strain GHA 180 does not have a common mechanism of toxicity with other substances. For information regarding EPA's efforts to determine which chemicals have a common mechanism of toxicity and to evaluate the cumulative effects of such chemicals, see EPA's Web site at http://www.epa.gov/pesticides/cumulative.
VI. Determination of Safety for U.S. Population, Infants and Children Back to Top
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., 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 Bacillus pumilus strain GHA180. 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 Bacillus pumilus strain GHA 180 does not demonstrate toxic, pathogenic, and/or infective potential to mammals. Because there are no threshold effects of concern, the provision requiring an additional margin of safety does not apply.
VII. Other Considerations Back to Top
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 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 Bacillus pumilus strain GHA 180.
VIII. Conclusions Back to Top
Therefore, an exemption is established for residues of Bacillus pumilus strain GHA180 in or on all food commodities when used in accordance with good agricultural practices.

X. Statutory and Executive Order Reviews Back to Top
This final rule establishes an exemption from the requirement of 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 FFDCA section 408(d), 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.
XI. Congressional Review Act Back to Top
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).
