Killed, Nonviable Streptomyces
acidiscabies Strain RL–110T;
Exemption From the Requirement of a
Tolerance
Environmental Protection
Agency (EPA).
ACTION: Final rule.
AGENCY:
This regulation establishes an
exemption from the requirement of a
tolerance 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. Marrone Bio Innovations, 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 killed, nonviable
Streptomyces acidiscabies strain RL–
110T under the FFDCA.
DATES: This regulation is effective June
13, 2012. Objections and requests for
hearings must be received on or before
August 13, 2012, and must be filed in
accordance with the instructions
provided in 40 CFR part 178 (see also

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

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

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

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

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.

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
VerDate Mar<15>2010

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).

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).
