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 0F7681) E:\FR\FM\13JNR1.SGM 13JNR1 35292 Federal Register / Vol. 77, No. 114 / Wednesday, June 13, 2012 / Rules and Regulations erowe on DSK2VPTVN1PROD with RULES by Marrone Bio Innovations, Inc., 2121 Second St., Suite B–107, Davis, CA 95618. The petition requested that 40 CFR part 180 be amended by establishing an exemption from the requirement of a tolerance for residues of Streptomyces acidiscabies strain RL– 110T. This notice referenced a summary of the petition prepared by the petitioner, Marrone Bio Innovations, Inc., which is available in the docket via 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 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. III. Toxicological Profile Consistent with section 408(b)(2)(D) of FFDCA, EPA reviewed the available scientific data and other relevant information in support of this action and considered its validity, completeness, and reliability and the VerDate Mar<15>2010 12:20 Jun 12, 2012 Jkt 226001 relationship of this information to human risk. EPA also considered available information concerning the variability of the sensitivities of major identifiable subgroups of consumers, including infants and children. A. Overview of Streptomyces acidiscabies Strain RL–110T Streptomyces species are commonly found in agricultural settings (i.e., soils and decaying plant material) and are present on fresh produce of all kinds with no known adverse effects. Indeed, the Manual of Clinical Microbiology (9th edition) (Ref. 2) states that the primary ecological niche for aerobic actinomycetes, such as Streptomyces acidiscabies strain RL–110T, is likely decaying plant material. The Manual of Clinical Microbiology (9th edition) (Ref. 2) further states that infections caused by Streptomyces species are infrequent and limited to species unrelated to acidiscabies and does not identify Streptomyces acidiscabies as clinically significant. No food borne disease outbreaks associated with Streptomyces species or mammalian active toxin production from Streptomyces species, including Streptomyces acidiscabies, have been reported. Streptomyces species have been used in pesticide products to control various pests of agricultural products. In conjunction with the registration of some of these pesticide products, EPA established the following exemptions from the requirement of a tolerance: 1. Streptomyces sp. (now griseoviridis) strain K61 (40 CFR 180.1120)—See the Federal Register of April 21, 1993 (58 FR 21402) (FRL– 4577–9). 2. Streptomyces lydicus WYEC 108 (40 CFR 180.1253)—See the Federal Register of June 3, 2004 (69 FR 31297) (FRL–7361–3). Streptomyces acidiscabies strain RL– 110T was isolated from scab-infected potatoes in Maine and New York. The pesticide active ingredient consists of killed, nonviable Streptomyces acidiscabies strain RL–110T cells and spent fermentation media. Thaxtomin A, a phytotoxin produced by Streptomyces acidiscabies strain RL– 110T, provides the herbicide mode of action. B. 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 killed, nonviable Streptomyces acidiscabies strain RL–110T in or on all food commodities have been fulfilled PO 00000 Frm 00048 Fmt 4700 Sfmt 4700 with data submitted by the petitioner or data waiver requests that have been granted by EPA. Results of acceptable (i.e., data that are scientifically sound and useful for risk assessment) toxicity tests (acute oral, dermal, and inhalation toxicity), primary eye and dermal irritation tests, and a skin sensitization test, all of which addressed potential routes of exposure to the active ingredient, revealed little to no toxicity, irritation, or sensitization attributed to killed, nonviable Streptomyces acidiscabies strain RL–110T. Moreover, the acute toxicity and primary irritation tests received a Toxicity Category IV classification (see 40 CFR 156.62). Finally, the results of an acute intravenous injection toxicity/ pathogenicity test demonstrated that live Streptomyces acidiscabies strain RL–110T were not toxic, infective and/ or pathogenic to the test animals. The overall conclusions from all toxicological information submitted by the petitioner are briefly described in this unit, while more in-depth synopses of some study results can be found in the associated Biopesticides Registration Action Document (BRAD) provided as a reference in Unit IX. (Ref. 1). 1. Acute oral toxicity/pathogenicity (Harmonized Guideline 885.3050) and acute pulmonary toxicity/pathogenicity (Harmonized Guideline 885.3150) (Master Record Identification Number (MRID No.) 479468–17). EPA waived the acute oral toxicity/pathogenicity and acute pulmonary toxicity/pathogenicity data requirements for the killed microorganism, but required the intravenous injection acute toxicity/ pathogenicity study to verify the product, under a ‘‘worst case’’ scenario, would not be toxic and/or pathogenic to the test animals. The toxicity component of the acute oral toxicity/pathogenicity and acute pulmonary toxicity/pathogenicity data requirements was fulfilled by MRID No. 479468–02 (acute oral toxicity, described in this unit) and MRID No. 479468–04 (acute inhalation toxicity, described in this unit), respectively. 2. Acute injection toxicity/ pathogenicity (intravenous)—rat (Harmonized Guideline 885.3200; MRID No. 479468–08). An acceptable acute injection toxicity/pathogenicity study demonstrated that live Streptomyces acidiscabies strain RL–110T was not toxic, infective, and/or pathogenic to rats when administered intravenously in a single dose of 9.0 × 106 colony-forming units (CFU) per rat. 3. Acute oral toxicity—rat (Harmonized Guideline 870.1100; MRID No. 479468–02). An acceptable acute oral toxicity study with a test substance E:\FR\FM\13JNR1.SGM 13JNR1 Federal Register / Vol. 77, No. 114 / Wednesday, June 13, 2012 / Rules and Regulations erowe on DSK2VPTVN1PROD with RULES containing killed, nonviable Streptomyces acidiscabies strain RL– 110T demonstrated that the oral median lethal dose (LD50) (i.e., a statistically derived single dose that can be expected to cause death in 50% of test animals) was greater than 5,000 mg/kg for female rats. This is the limit dose, and no further acute oral testing is required. (Toxicity Category IV). 4. Acute dermal toxicity—rat (Harmonized Guideline 870.1200; MRID No. 479468–03). An acceptable acute dermal toxicity study with a test substance containing killed, nonviable Streptomyces acidiscabies strain RL– 110T demonstrated that the dermal LD50 was greater than 5,050 mg/kg for male and female rats combined. This is the limit dose, and no further acute dermal testing is required. (Toxicity Category IV). 5. Acute inhalation toxicity—rat (Harmonized Guideline 870.1300; MRID No. 479468–04). An acceptable acute inhalation study with a test substance containing killed, nonviable Streptomyces acidiscabies strain RL– 110T demonstrated that the inhalation median lethal concentration (LC50) was greater than 2.21 mg/L (the limit or maximum dose required to be tested) for male and female rats combined. (Toxicity Category IV). 6. Primary dermal irritation—rabbit (Harmonized Guideline 870.2500; MRID No. 479468–06). An acceptable primary dermal irritation study demonstrated that a test substance containing killed, nonviable Streptomyces acidiscabies strain RL–110T was not irritating to the skin of rabbits (Toxicity Category IV). 7. Skin sensitization—guinea pig (Harmonized Guideline 870.2600; MRID No. 479468–07). An acceptable dermal sensitization study demonstrated that a test substance containing killed, nonviable Streptomyces acidiscabies strain RL–110T was not a dermal sensitizer to guinea pigs. IV. 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 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 1. Food exposure. Killed, nonviable Streptomyces acidiscabies strain RL– 110T will be applied as a herbicide to agricultural crops pre-plant, at-plant VerDate Mar<15>2010 12:20 Jun 12, 2012 Jkt 226001 and post-plant and may be applied up to the day of harvest. Exposure to this active ingredient through food is possible but is expected to be minimal for the following reasons: i. The proposed pesticide product will be diluted prior to application. ii. Pre-plant applications will occur 1–45 days or more before planting. iii. At-plant applications will be broadcast and incorporated into the soil mechanically or by rainfall or sprinkler application. iv. Post-plant applications for trees will be made as a broadcast or banded application to soil surface below established trees or between tree rows and incorporated into the soil by rainfall, irrigation or mechanical incorporation. v. Post-plant lay-by and split application will be made between rows and incorporated into the soil. vi. Application to rice fields is followed by flooding or partially draining and re-flooding the fields. and vii. Rainfall and sprinkler irrigation will further wash residues of the pesticide from treated crops. Following all applications, killed, nonviable Streptomyces acidiscabies strain RL–110T will naturally degrade due to consumption by other biological organisms, including bacteria and fungi (Ref. 3). In the unlikely event that any residues of the pesticide remain in or on consumed food, no adverse effects would be expected, based on the lack of toxicity, infectivity, and/or pathogenicity demonstrated in the submitted studies. 2. Drinking water exposure. Exposure to residues of killed, nonviable Streptomyces acidiscabies strain RL– 110T in consumed drinking water is unlikely, since the majority of the proposed use patterns (ground and aerial) include measures to incorporate the herbicide into the soil; however, residues may appear at low levels in ground and surface water from these uses due to runoff or drainage from treated fields, or by spray drift. These residues will be minimized by natural degradation of the active ingredient by microbial activity (Ref. 3). Furthermore, since application of the product is concentrated in upper soil strata, movement through the soils would likely filter out any remaining product. The proposed directions for applications to established turf in landscapes provide for dilution of the product prior to application, but do not include measures to incorporate the product. Since established turf constitutes significant ground cover, this, in itself, would be expected to PO 00000 Frm 00049 Fmt 4700 Sfmt 4700 35293 reduce the potential runoff of the pesticide into surface water and percolation to ground water. The proposed directions for applications to ornamentals in landscapes specify dilution prior to application and incorporation by irrigation or raking into the soil. These measures, along with natural degradation and incorporation of the product into upper soil strata, will reduce the potential for runoff into surface or ground water. The proposed use in rice provides the greatest potential for residues of killed, nonviable Streptomyces acidiscabies strain RL–110T to appear in ground and surface water, since application to rice fields is followed by flooding the treated fields. If residues of Streptomyces acidiscabies strain RL–110T are transferred to surface or ground waters that are intended for eventual human consumption, and subjected to sanitation (e.g., chlorination, pH adjustments, filtration, high temperatures) in drinking water treatment plants, the residues would likely be removed from the finished drinking water (Ref. 4). In the unlikely event that any residues of the pesticide occur in drinking water even after being processed at a water treatment facility, no adverse effects would be expected, based on the lack of toxicity and pathogenicity demonstrated in the submitted studies. B. Other Non-Occupational Exposure Given the natural occurrence of Streptomyces acidiscabies in soil (Refs. 5 and 6), non-occupational and residential exposure may already be occurring. Application of killed, nonviable Streptomyces acidiscabies strain RL–110T to established turf in residential and landscape settings will result in exposure via the dermal and inhalation routes. Any such exposures are expected to be minimal, since the concentration of killed, nonviable Streptomyces acidiscabies strain RL– 110T is diluted prior to application and the active ingredient is not expected to persist (see the food and drinking water exposure sections in this unit). In the unlikely event that the proposed uses of the pesticide result in residential, non-occupational exposure, no adverse effects would be expected, based on the lack of toxicity, irritation and sensitization demonstrated in available data (see additional discussion in Unit III.). 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 E:\FR\FM\13JNR1.SGM 13JNR1 35294 Federal Register / Vol. 77, No. 114 / Wednesday, June 13, 2012 / Rules and Regulations erowe on DSK2VPTVN1PROD with RULES VI. Determination of Safety for U.S. 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 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 (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 discussed in Unit III.B., EPA concludes that there are no threshold effects of concern to infants, children or adults when killed, nonviable Streptomyces acidiscabies strain RL–110T is used as labeled in accordance with good agricultural practices. As a result, EPA concludes VerDate Mar<15>2010 12:20 Jun 12, 2012 Jkt 226001 that no additional margin of exposure (safety) is necessary. Moreover, based on the same data and EPA analyses as presented in this unit, 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 killed, nonviable Streptomyces acidiscabies strain RL–110T when it is used as labeled and in accordance with good agricultural practices as a pre- or post-emergent herbicide. 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 killed, nonviable Streptomyces acidiscabies strain RL–110T do not demonstrate toxic potential to mammals, including infants and children. exemption from the requirement of a tolerance for residues of Streptomyces acidiscabies strain RL–110T in or on all agricultural commodities. Two modifications have been made to the requested tolerance exemption. First, based upon the data and information available to the Agency, EPA is adding the qualifiers ‘‘killed’’ and ‘‘nonviable’’ before the microorganism’s taxonomic name and unique identifier. Use of these qualifiers is now consistent with the representation of this active ingredient in other associated regulatory documents and should assist in preventing confusion regarding its nomenclature in the future. Second, EPA is changing ‘‘in or on all agricultural commodities’’ to ‘‘in or on all food commodities’’ to align with the terminology the Agency currently uses when establishing tolerance exemptions for residues of other like active ingredients. VII. Other Considerations VIII. Conclusions A. Analytical Enforcement Methodology 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.’’ EPA has not found killed, nonviable Streptomyces acidiscabies strain RL– 110T to share a common mechanism of toxicity with any other substances, and killed, nonviable Streptomyces acidiscabies strain RL–110T does not appear to produce a toxic metabolite produced by other substances. For the purposes of this tolerance action, EPA has assumed that killed, nonviable Streptomyces acidiscabies strain RL– 110T does not have a common mechanism of toxicity with other substances. For information regarding EPA’s efforts to determine chemicals that 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. EPA concludes that there is reasonable certainty that no harm will result to the U.S. population, including infants and children, from aggregate exposure to residues of killed, nonviable Streptomyces acidiscabies strain RL– 110T. Therefore, an exemption from the requirement of a tolerance is established for residues of killed, nonviable Streptomyces acidiscabies strain RL– 110T in or on all food commodities when applied as a pre- or post-emergent herbicide and used in accordance with good agricultural practices. An analytical method is not required for enforcement purposes for the reasons stated in this document and because EPA 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. 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 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 killed, nonviable Streptomyces acidiscabies strain RL–110T. C. Revisions to Requested Tolerance Exemption In the Federal Register of March 10, 2010, EPA announced Marrone Bio Innovations, Inc.’s filing of a pesticide petition that proposed establishing an PO 00000 Frm 00050 Fmt 4700 Sfmt 4700 IX.

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.

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 0F7681)

[[Page 35292]]

by Marrone Bio Innovations, Inc., 2121 Second St., Suite B-107, Davis, 
CA 95618. The petition requested that 40 CFR part 180 be amended by 
establishing an exemption from the requirement of a tolerance for 
residues of Streptomyces acidiscabies strain RL-110\T\. This notice 
referenced a summary of the petition prepared by the petitioner, 
Marrone Bio Innovations, Inc., which is available in the docket via 
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 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.

III. Toxicological Profile

    Consistent with section 408(b)(2)(D) of FFDCA, EPA 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 also 
considered available information concerning the variability of the 
sensitivities of major identifiable subgroups of consumers, including 
infants and children.

A. Overview of Streptomyces acidiscabies Strain RL-110\T\

    Streptomyces species are commonly found in agricultural settings 
(i.e., soils and decaying plant material) and are present on fresh 
produce of all kinds with no known adverse effects. Indeed, the Manual 
of Clinical Microbiology (9th edition) (Ref. 2) states that the primary 
ecological niche for aerobic actinomycetes, such as Streptomyces 
acidiscabies strain RL-110\T\, is likely decaying plant material. The 
Manual of Clinical Microbiology (9th edition) (Ref. 2) further states 
that infections caused by Streptomyces species are infrequent and 
limited to species unrelated to acidiscabies and does not identify 
Streptomyces acidiscabies as clinically significant. No food borne 
disease outbreaks associated with Streptomyces species or mammalian 
active toxin production from Streptomyces species, including 
Streptomyces acidiscabies, have been reported. Streptomyces species 
have been used in pesticide products to control various pests of 
agricultural products. In conjunction with the registration of some of 
these pesticide products, EPA established the following exemptions from 
the requirement of a tolerance:
    1. Streptomyces sp. (now griseoviridis) strain K61 (40 CFR 
180.1120)--See the Federal Register of April 21, 1993 (58 FR 21402) 
(FRL-4577-9).
    2. Streptomyces lydicus WYEC 108 (40 CFR 180.1253)--See the Federal 
Register of June 3, 2004 (69 FR 31297) (FRL-7361-3).
    Streptomyces acidiscabies strain RL-110\T\ was isolated from scab-
infected potatoes in Maine and New York. The pesticide active 
ingredient consists of killed, nonviable Streptomyces acidiscabies 
strain RL-110\T\ cells and spent fermentation media. Thaxtomin A, a 
phytotoxin produced by Streptomyces acidiscabies strain RL-110\T\, 
provides the herbicide mode of action.

B. 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 killed, nonviable Streptomyces acidiscabies strain RL-
110\T\ in or on all food commodities have been fulfilled with data 
submitted by the petitioner or data waiver requests that have been 
granted by EPA. Results of acceptable (i.e., data that are 
scientifically sound and useful for risk assessment) toxicity tests 
(acute oral, dermal, and inhalation toxicity), primary eye and dermal 
irritation tests, and a skin sensitization test, all of which addressed 
potential routes of exposure to the active ingredient, revealed little 
to no toxicity, irritation, or sensitization attributed to killed, 
nonviable Streptomyces acidiscabies strain RL-110\T\. Moreover, the 
acute toxicity and primary irritation tests received a Toxicity 
Category IV classification (see 40 CFR 156.62). Finally, the results of 
an acute intravenous injection toxicity/pathogenicity test demonstrated 
that live Streptomyces acidiscabies strain RL-110\T\ were not toxic, 
infective and/or pathogenic to the test animals.
    The overall conclusions from all toxicological information 
submitted by the petitioner are briefly described in this unit, while 
more in-depth synopses of some study results can be found in the 
associated Biopesticides Registration Action Document (BRAD) provided 
as a reference in Unit IX. (Ref. 1).
    1. Acute oral toxicity/pathogenicity (Harmonized Guideline 
885.3050) and acute pulmonary toxicity/pathogenicity (Harmonized 
Guideline 885.3150) (Master Record Identification Number (MRID No.) 
479468-17). EPA waived the acute oral toxicity/pathogenicity and acute 
pulmonary toxicity/pathogenicity data requirements for the killed 
microorganism, but required the intravenous injection acute toxicity/
pathogenicity study to verify the product, under a ``worst case'' 
scenario, would not be toxic and/or pathogenic to the test animals.
    The toxicity component of the acute oral toxicity/pathogenicity and 
acute pulmonary toxicity/pathogenicity data requirements was fulfilled 
by MRID No. 479468-02 (acute oral toxicity, described in this unit) and 
MRID No. 479468-04 (acute inhalation toxicity, described in this unit), 
respectively.
    2. Acute injection toxicity/pathogenicity (intravenous)--rat 
(Harmonized Guideline 885.3200; MRID No. 479468-08). An acceptable 
acute injection toxicity/pathogenicity study demonstrated that live 
Streptomyces acidiscabies strain RL-110\T\ was not toxic, infective, 
and/or pathogenic to rats when administered intravenously in a single 
dose of 9.0 x 10\6\ colony-forming units (CFU) per rat.
    3. Acute oral toxicity--rat (Harmonized Guideline 870.1100; MRID 
No. 479468-02). An acceptable acute oral toxicity study with a test 
substance

[[Page 35293]]

containing killed, nonviable Streptomyces acidiscabies strain RL-110\T\ 
demonstrated that the oral median lethal dose (LD50) (i.e., 
a statistically derived single dose that can be expected to cause death 
in 50% of test animals) was greater than 5,000 mg/kg for female rats. 
This is the limit dose, and no further acute oral testing is required. 
(Toxicity Category IV).
    4. Acute dermal toxicity--rat (Harmonized Guideline 870.1200; MRID 
No. 479468-03). An acceptable acute dermal toxicity study with a test 
substance containing killed, nonviable Streptomyces acidiscabies strain 
RL-110\T\ demonstrated that the dermal LD50 was greater than 
5,050 mg/kg for male and female rats combined. This is the limit dose, 
and no further acute dermal testing is required. (Toxicity Category 
IV).
    5. Acute inhalation toxicity--rat (Harmonized Guideline 870.1300; 
MRID No. 479468-04). An acceptable acute inhalation study with a test 
substance containing killed, nonviable Streptomyces acidiscabies strain 
RL-110\T\ demonstrated that the inhalation median lethal concentration 
(LC50) was greater than 2.21 mg/L (the limit or maximum dose 
required to be tested) for male and female rats combined. (Toxicity 
Category IV).
    6. Primary dermal irritation--rabbit (Harmonized Guideline 
870.2500; MRID No. 479468-06). An acceptable primary dermal irritation 
study demonstrated that a test substance containing killed, nonviable 
Streptomyces acidiscabies strain RL-110\T\ was not irritating to the 
skin of rabbits (Toxicity Category IV).
    7. Skin sensitization--guinea pig (Harmonized Guideline 870.2600; 
MRID No. 479468-07). An acceptable dermal sensitization study 
demonstrated that a test substance containing killed, nonviable 
Streptomyces acidiscabies strain RL-110\T\ was not a dermal sensitizer 
to guinea pigs.

IV. 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).

A. Dietary Exposure

    1. Food exposure. Killed, nonviable Streptomyces acidiscabies 
strain RL-110\T\ will be applied as a herbicide to agricultural crops 
pre-plant, at-plant and post-plant and may be applied up to the day of 
harvest. Exposure to this active ingredient through food is possible 
but is expected to be minimal for the following reasons:
    i. The proposed pesticide product will be diluted prior to 
application.
    ii. Pre-plant applications will occur 1-45 days or more before 
planting.
    iii. At-plant applications will be broadcast and incorporated into 
the soil mechanically or by rainfall or sprinkler application.
    iv. Post-plant applications for trees will be made as a broadcast 
or banded application to soil surface below established trees or 
between tree rows and incorporated into the soil by rainfall, 
irrigation or mechanical incorporation.
    v. Post-plant lay-by and split application will be made between 
rows and incorporated into the soil.
    vi. Application to rice fields is followed by flooding or partially 
draining and re-flooding the fields. and
    vii. Rainfall and sprinkler irrigation will further wash residues 
of the pesticide from treated crops.
    Following all applications, killed, nonviable Streptomyces 
acidiscabies strain RL-110\T\ will naturally degrade due to consumption 
by other biological organisms, including bacteria and fungi (Ref. 3).
    In the unlikely event that any residues of the pesticide remain in 
or on consumed food, no adverse effects would be expected, based on the 
lack of toxicity, infectivity, and/or pathogenicity demonstrated in the 
submitted studies.
    2. Drinking water exposure. Exposure to residues of killed, 
nonviable Streptomyces acidiscabies strain RL-110\T\ in consumed 
drinking water is unlikely, since the majority of the proposed use 
patterns (ground and aerial) include measures to incorporate the 
herbicide into the soil; however, residues may appear at low levels in 
ground and surface water from these uses due to runoff or drainage from 
treated fields, or by spray drift. These residues will be minimized by 
natural degradation of the active ingredient by microbial activity 
(Ref. 3). Furthermore, since application of the product is concentrated 
in upper soil strata, movement through the soils would likely filter 
out any remaining product.
    The proposed directions for applications to established turf in 
landscapes provide for dilution of the product prior to application, 
but do not include measures to incorporate the product. Since 
established turf constitutes significant ground cover, this, in itself, 
would be expected to reduce the potential runoff of the pesticide into 
surface water and percolation to ground water. The proposed directions 
for applications to ornamentals in landscapes specify dilution prior to 
application and incorporation by irrigation or raking into the soil. 
These measures, along with natural degradation and incorporation of the 
product into upper soil strata, will reduce the potential for runoff 
into surface or ground water.
    The proposed use in rice provides the greatest potential for 
residues of killed, nonviable Streptomyces acidiscabies strain RL-
110\T\ to appear in ground and surface water, since application to rice 
fields is followed by flooding the treated fields. If residues of 
Streptomyces acidiscabies strain RL-110\T\ are transferred to surface 
or ground waters that are intended for eventual human consumption, and 
subjected to sanitation (e.g., chlorination, pH adjustments, 
filtration, high temperatures) in drinking water treatment plants, the 
residues would likely be removed from the finished drinking water (Ref. 
4). In the unlikely event that any residues of the pesticide occur in 
drinking water even after being processed at a water treatment 
facility, no adverse effects would be expected, based on the lack of 
toxicity and pathogenicity demonstrated in the submitted studies.

B. Other Non-Occupational Exposure

    Given the natural occurrence of Streptomyces acidiscabies in soil 
(Refs. 5 and 6), non-occupational and residential exposure may already 
be occurring. Application of killed, nonviable Streptomyces 
acidiscabies strain RL-110\T\ to established turf in residential and 
landscape settings will result in exposure via the dermal and 
inhalation routes. Any such exposures are expected to be minimal, since 
the concentration of killed, nonviable Streptomyces acidiscabies strain 
RL-110\T\ is diluted prior to application and the active ingredient is 
not expected to persist (see the food and drinking water exposure 
sections in this unit).
    In the unlikely event that the proposed uses of the pesticide 
result in residential, non-occupational exposure, no adverse effects 
would be expected, based on the lack of toxicity, irritation and 
sensitization demonstrated in available data (see additional discussion 
in Unit III.).

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

[[Page 35294]]

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.''
    EPA has not found killed, nonviable Streptomyces acidiscabies 
strain RL-110\T\ to share a common mechanism of toxicity with any other 
substances, and killed, nonviable Streptomyces acidiscabies strain RL-
110\T\ does not appear to produce a toxic metabolite produced by other 
substances. For the purposes of this tolerance action, EPA has assumed 
that killed, nonviable Streptomyces acidiscabies strain RL-110\T\ does 
not have a common mechanism of toxicity with other substances. For 
information regarding EPA's efforts to determine chemicals that 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, 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 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 (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 discussed in 
Unit III.B., EPA concludes that there are no threshold effects of 
concern to infants, children or adults when killed, nonviable 
Streptomyces acidiscabies strain RL-110\T\ is used as labeled in 
accordance with good agricultural practices. As a result, EPA concludes 
that no additional margin of exposure (safety) is necessary.
    Moreover, based on the same data and EPA analyses as presented in 
this unit, 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 
killed, nonviable Streptomyces acidiscabies strain RL-110\T\ when it is 
used as labeled and in accordance with good agricultural practices as a 
pre- or post-emergent herbicide. 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 killed, nonviable 
Streptomyces acidiscabies strain RL-110\T\ do not demonstrate toxic 
potential to mammals, including infants and children.

VII. Other Considerations

A. Analytical Enforcement Methodology

    An analytical method is not required for enforcement purposes for 
the reasons stated in this document and because EPA 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. 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 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 killed, nonviable 
Streptomyces acidiscabies strain RL-110\T\.

C. Revisions to Requested Tolerance Exemption

    In the Federal Register of March 10, 2010, EPA announced Marrone 
Bio Innovations, Inc.'s filing of a pesticide petition that proposed 
establishing an exemption from the requirement of a tolerance for 
residues of Streptomyces acidiscabies strain RL-110\T\ in or on all 
agricultural commodities. Two modifications have been made to the 
requested tolerance exemption. First, based upon the data and 
information available to the Agency, EPA is adding the qualifiers 
``killed'' and ``nonviable'' before the microorganism's taxonomic name 
and unique identifier. Use of these qualifiers is now consistent with 
the representation of this active ingredient in other associated 
regulatory documents and should assist in preventing confusion 
regarding its nomenclature in the future. Second, EPA is changing ``in 
or on all agricultural commodities'' to ``in or on all food 
commodities'' to align with the terminology the Agency currently uses 
when establishing tolerance exemptions for residues of other like 
active ingredients.

VIII. Conclusions

    EPA concludes that there is reasonable certainty that no harm will 
result to the U.S. population, including infants and children, from 
aggregate exposure to residues of killed, nonviable Streptomyces 
acidiscabies strain RL-110\T\. Therefore, an exemption from the 
requirement of a tolerance is established for residues of killed, 
nonviable Streptomyces acidiscabies strain RL-110\T\ in or on all food 
commodities when applied as a pre- or post-emergent herbicide and used 
in accordance with good agricultural practices.

X. 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).

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).
