II. Background and Statutory Findings
In the Federal Register of July 31,
2008 (73 FR 44719) (FRL–8374–3), 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 7E7276)
¨
by Laboratoires Goemar SA c/o SciReg,
Inc., 12733 Director’s Loop,
Woodbridge, VA 22192. The petition
requested that 40 CFR part 180 be
amended by establishing an exemption
VerDate Nov<24>2008
15:09 Feb 23, 2010
Jkt 220001
from the requirement of a tolerance for
residues of laminarin. This notice
included a summary of the petition
prepared by the petitioner Laboratoires
¨
Goemar SA c/o SciReg, Inc. There were
no comments received in response to
the notice of filing.
Section 408(c)(2)(A)(i) of FFDCA
allows EPA to establish an exemption
from the requirement for a tolerance (the
legal limit for a pesticide chemical
residue in or on a food) only if EPA
determines that the exemption is ‘‘safe.’’
Section 408(c)(2)(A)(ii) of FFDCA
defines ‘‘safe’’ to mean that ‘‘there is a
reasonable certainty that no harm will
result from aggregate exposure to the
pesticide chemical residue, including
all anticipated dietary exposures and all
other exposures for which there is
reliable information.’’ This includes
exposure through drinking water and in
residential settings, but does not include
occupational exposure. Pursuant to
section 408(c)(2)(B) of FFDCA, in
establishing or maintaining in effect an
exemption from the requirement of a
tolerance, EPA must take into account
the factors set forth in section
408(b)(2)(C) of FFDCA, which require
EPA to give special consideration to
exposure of infants and children to the
pesticide chemical residue in
establishing a tolerance and to ‘‘ensure
that there is a reasonable certainty that
no harm will result to infants and
children from aggregate exposure to the
pesticide chemical residue.... ’’
Additionally, section 408(b)(2)(D) of
FFDCA requires that the Agency
consider ‘‘available information
concerning the cumulative effects of a
particular pesticide’s residues’’ and
‘‘other substances that have a common
mechanism of toxicity.’’
EPA performs a number of analyses to
determine the risks from aggregate
exposure to pesticide residues. First,
EPA determines the toxicity of
pesticides. Second, EPA examines
exposure to the pesticide through food,
drinking water, and through other
exposures that occur as a result of
pesticide use in residential settings.
III. Toxicological Profile
Consistent with section 408(b)(2)(D)
of FFDCA, EPA has reviewed the
available scientific data and other
relevant information in support of this
action and considered its validity,
completeness, and reliability and the
relationship of this information to
human risk. EPA has also considered
available information concerning the
variability of the sensitivities of major
identifiable subgroups of consumers,
including infants and children.

Laminarin, a naturally occurring bglucan (polysaccharide carbohydrate),
may be extracted from many types of
brown algae (e.g., Laminaria digitata).
Generally, b-glucans are major
constituents in the bran of most cereal
grains and are intentionally added to
many dietary supplements and texturing
agents; therefore, these carbohydrates
are typically consumed as a regular part
of the human diet. Laminarin,
specifically, is an integral part of the
human diet in countries such as Ireland,
France, and Japan, where Laminaria
digitata is used for sea-vegetable
production. As a biochemical active
ingredient, laminarin stimulates the
natural defense reactions of agricultural
crops such as fruiting vegetables,
tomato, eggplant, pepper, zucchini,
cucurbits, watermelon, melons, grape,
apple, pear, and strawberries against
particular disease organisms (e.g., gray
mold, powdery mildew, downy mildew,
fire blight, and bacterial spot). As a
naturally occurring oligosaccharide (a
carbohydrate), residues of the active
ingredient are indistinguishable from
other naturally occurring plant
oligosaccharides. In addition to the
extensive history of consumption of bglucans—particularly laminarin in this
case—without documented
toxicological effects, the data submitted
to the Agency, in conjunction with and
in support of this tolerance exemption,
confirm that laminarin is virtually
nontoxic and poses no dietary risks to
humans.
Because laminarin is considered
‘‘toxicologically innocuous,’’ no residue
studies are required to support a
tolerance exemption. However,
laminarin’s low toxicity profile
notwithstanding, another justification
for this exemption from the requirement
of a tolerance is the unlikelihood of
residues for this biochemical pesticide
in or on food. Laminarin is intended for
application as a systemic acquired
resistance (SAR) inducer—a
preventative mode of action. As such, it
is applied early in a crop’s life cycle—
in its growing stages—to help build
immunity to disease organisms such as
mold and bacterial infection.
Furthermore, as a biochemical, it is
prone to biodegrade rapidly. Data
indicate that the active ingredient is
more than 65% biodegraded after two
weeks (Master Record Identification
Number (MRID No.) 472649–54).
Calculations indicate that it would be
fully biodegraded long before any
consumption would occur because the
most likely final application of the
pesticide would occur early in the
growing season for plants treated with
E:\FR\FM\24FER1.SGM
24FER1
8254
Federal Register / Vol. 75, No. 36 / Wednesday, February 24, 2010 / Rules and Regulations
this pesticide. Accordingly, no
exposures beyond background levels are
expected.
Summaries of the toxicological data
submitted in support of this exemption
from the requirement of a tolerance
follow:
cprice-sewell on DSK2BSOYB1PROD with RULES
A. Acute Toxicity
Acute toxicity studies, submitted to
support the registration of the end-use
product containing laminarin, confirm a
low toxicity profile and buttress the
finding that this active ingredient poses
no significant human health risk with
regard to new food uses. Altogether, the
acute toxicity data show virtual
nontoxicity for all routes of exposure
and suggest that any dietary risks
associated with this carbohydrate would
be negligible.
1. The acute oral median lethal doses
(LD50s) in rats were greater than 2,000
milligrams per kilogram (mg/kg) and
confirmed negligible toxicity through
the oral route. There were no observed
toxicological effects on the test subjects
in either of the two acute oral studies
submitted (MRID Nos. 472649–30 and
472649–73). Laminarin is Toxicity
Category III for acute oral toxicity.
2. The acute dermal median lethal
dose (LD50) in rats was greater than
5,000 mg/kg. These data substantiated
laminarin’s relative dermal nontoxicity
to the general public (MRID Nos.
472649–31 and 472649–74). Laminarin
is Toxicity Category IV for acute dermal
toxicity.
3. The acute inhalation median lethal
concentration (LC50) was greater than
1.02 milligrams per liter (mg/L) in rats
and showed no significant inhalation
toxicity (MRID No. 472649–32).
Laminarin is Toxicity Category III for
acute inhalation toxicity.
4. A skin irritation study on rabbits
indicated that laminarin was not
irritating to the skin (MRID No. 472649–
34). Laminarin is Toxicity Category IV
for dermal irritiation.
5. Data indicated laminarin is not a
dermal sensitizer (MRID Nos. 472649–
35 and 472649–78).
Data indicate that laminarin is not
acutely toxic. No toxic endpoints were
established in any of the acute toxicity
studies, and no significant toxicological
effects were observed in any of the acute
toxicity studies.
B. Mutagenicity
Three mutagenicity studies, using
laminarin as the test substance, were
performed. These studies are sufficient
to confirm that there are no expected
dietary or non-occupational risks of
mutagenicity with regard to new food
uses.
VerDate Nov<24>2008
15:09 Feb 23, 2010
Jkt 220001
1. The Reverse Mutation Assay (MRID
No. 472649–42) showed that laminarin
did not induce mutant colonies relative
to control groups.
2. The In vitro Mammalian Cells in
Culture Assay (MRID No. 472649–43)
demonstrated that laminarin did not
damage chromosomes or the mitotic
apparatus of bone marrow cells.
3. A Bone Marrow Micronucleus
Assay (MRID No. 472649–44) indicated
that no toxicity was noted in either sex
at any dose up to the limit dose of 2,000
mg/kg.
C. Subchronic Toxicity
Based on its biodegradation
properties, residues of laminarin are not
expected to result in significant dietary
exposure beyond the levels expected in
background dietary exposures.
Nonetheless, three subchronic oral
toxicity studies satisfied the data
requirements for subchronic toxicity
and indicated that laminarin has no
subchronic toxicological effect.
1. A 28–day Oral Toxicity Study
(MRID No. 472649–37) found no
toxicological effects regarding mortality,
clinical observations, neurotoxicity
assessment, body weight, food
consumption, hematology, clinical
chemistry, organ weights, and
macroscopic or microscopic
observations. The no observable effect
level (NOEL) was determined to be
1,000 milligrams per kilogram per day
(mg/kg/day).
2. A 90–day Oral Toxicity Study
(MRID No. 472649–38) found no
statistical difference in hematology,
clinical chemistry, or urinalysis
between test subjects and the control.
The NOAEL was determined to be 1,000
mg/kg/day.
3. Another 90–day Oral Toxicity
Study (MRID No. 472649–39) also found
no statistical difference in hematology,
clinical chemistry, or urinalysis
between test subjects and the control.
The NOAEL was again determined to be
1,000 mg/kg/day.
D. Developmental Toxicity
The data submitted to the Agency
demonstrate a clear lack of
developmental toxicity and supports the
Agency’s conclusion that there is no risk
of developmental toxicity associated
with new food uses. Data submitted to
the Agency satisfy the data requirements
for developmental toxicity and indicate
that laminarin poses negligible risk with
regard to developmental toxicity.
1. A Prenatal Developmental Toxicity
Study (MRID No. 472649–40) found no
significant treatment-related
reproductive effects or fetal
abnormalities and established a no
PO 00000
Frm 00016
Fmt 4700
Sfmt 4700
observable adverse effect level (NOAEL)
of 1,000 mg/kg/day.
2. A second Prenatal Developmental
Toxicity Study (MRID No. 472649–41)
also found no significant treatmentrelated reproductive effects or fetal
abnormalities and confirmed a NOAEL
of 1,000 mg/kg/day.
E. Effects on Endocrine Systems
There is no available evidence
demonstrating that laminarin is an
endocrine disruptor in humans. As a
result, the Agency is not requiring
information on the endocrine effects of
laminarin at this time. However, the
Endocrine Disruption Screening
Program (EDSP) has established a
protocol, which guides the Agency in
selecting suspect ingredients for review,
and the Agency reserves the right to
require new information should the
program require it. Presently, based on
the lack of exposure and the negligible
toxicity profile of laminarin, no adverse
effects to the endocrine are known or
expected. Overall, the lack of evidence
of endocrine disruption is consistent
with laminarin’s low toxicity profile
and supports this exemption from the
requirement of a tolerance.
IV. Aggregate Exposures
In examining aggregate exposure,
section 408 of FFDCA directs EPA to
consider available information
concerning exposures from the pesticide
residue in food and all other nonoccupational exposures, including
drinking water from ground water or
surface water and exposure through
pesticide use in gardens, lawns, or
buildings (residential and other indoor
uses).
A. Dietary Exposure
Because of laminarin’s ability to
biodegrade relatively quickly and the
typical time during plant growth that it
will be applied, the Agency does not
anticipate many residues being present
in or on food at the time of
consumption. Moreover, any residues
that are present in or on food at the time
of consumption as a result of pesticide
use are likely to be indistinguishable
from naturally occurring laminarin due
to its natural occurrence and ubiquitous
presence in foods and dietary
supplements. Finally, the Agency
believes that it is unlikely that any
exposure to the residues of laminarin
will result in dietary risks because of the
nontoxic mode of action as a SAR
inducer and the pesticide’s negligible
toxicity profile.
1. Food. Exposure to residues of
laminarin on foods is expected to be
negligible. Data submitted to the Agency
E:\FR\FM\24FER1.SGM
24FER1
Federal Register / Vol. 75, No. 36 / Wednesday, February 24, 2010 / Rules and Regulations
cprice-sewell on DSK2BSOYB1PROD with RULES
show that laminarin is 65% to 71%
biodegraded within two weeks, and that
it hydrolyzes very rapidly into glucose.
Because applications necessarily occur
early in the growing season (due to its
mode of action as a SAR inducer), and
given its short-lived presence on crops,
no significant pesticidal residues are
anticipated for harvested foods.
However, in the event of exposure to
residues of laminarin, no dietary risks
are anticipated. As described in Unit
III., acute, subchronic, mutagenic and
developmental studies support its
nontoxic profile. Furthermore, it is
already present in foods without any
known detrimental effects. Indeed, there
is no information in the public literature
suggesting any health issues to either
animals or plants relative to this
compound. Lastly, proposed rates of
application of laminarin will result in
substantially fewer residues in or on
foods as a result of pesticide application
than the quantities of laminarin already
consumed in foods and those allowed in
dietary supplements. In sum, no dietary
exposure is expected; however, any
potential dietary exposures would not
be expected to pose any quantifiable
risk, mainly due to laminarin’s nontoxic
profile.
2. Drinking water exposure. Residues
of laminarin are not expected to be
present in drinking water as
applications of laminarin are made
directly to terrestrial crops. Laminarin
residues are not expected to percolate
through the soil because residues are
not expected to persist beyond the time
it would typically take for any residues
to percolate into the groundwater. In the
event of errant spray drift or
extraordinary rainfall, laminarin will
not persist in water due to its rapid
hydrolyzation into glucose. Moreover,
given laminarin’s nontoxic profile as
described in Unit III., risks from
miniscule aquatic exposure would be
negligible. Altogether, drinking water
exposure is not expected to pose any
quantifiable risk due to both a lack of
residues and the nontoxicity of
laminarin.
B. Other Non-Occupational Exposure
Non-occupational exposure is not
expected because lamarin is not
approved for residential uses. The active
ingredient is applied directly to
commodities and degrades rapidly.
Furthermore, the Agency notes that
health risks are not expected from any
pesticidal exposure to this active
ingredient, no matter the circumstances.
An August 2009 Agency risk assessment
of laminarin clearly establishes that
even prolonged and regular
occupational exposures, which are
VerDate Nov<24>2008
15:09 Feb 23, 2010
Jkt 220001
associated with this active ingredient,
pose negligible risks. Laminarin is
characterized by its biodegradability,
low toxicity profile, nontoxic, SARinducing mode of action, and
demonstrable lack of dietary effects.
1. Dermal exposure. Nonoccupational dermal exposures to
laminarin are expected to be negligible
because of its directed agricultural use.
Even in the event of dermal exposure to
residues, the nontoxic profile of
laminarin (as described in Unit III.) is
not expected to result in any risks
through this route of exposure.
2. Inhalation exposure. Nonoccupational inhalation exposures are
not expected to result from the
agricultural uses of laminarin. Any
inhalation exposure associated with this
new agricultural use pattern is expected
to be occupational in nature.
V. Cumulative Effects
Pursuant to FFDCA section
408(b)(2)(D)(v), EPA has considered
available information concerning the
cumulative effects of exposure to
laminarin residues and other substances
that have a common mechanism of
toxicity. These considerations include
the possible cumulative effects of such
residues on infants and children.
Because laminarin operates through a
nontoxic mode of action, there is no
common mechanism of toxicity between
this and any other substances; therefore,
this provision does not apply.
Nevertheless, given that no exposure to
residues are expected when applications
are made in accordance with EPAapproved labeling and good agricultural
practices, and laminarin has a long
history of dietary consumption without
incident, the Agency concludes that
there is no reason to anticipate
cumulative effects from the residues of
this active ingredient with other related
pesticides.
VI. Determination of Safety for U.S.
Population, Infants and Children
Health risks to humans, including
infants and children, are considered
negligible with regard to the pesticidal
use of laminarin. As illustrated in Unit
III., acute toxicity studies indicate that
laminarin has negligible toxicity. It is
ubiquitous in nature and present in
fruits and vegetables. To date, there is
no history of toxicological incident
involving its consumption and its use in
food supplements is already allowed by
the United States Food and Drug
Administration. Of equal note, little to
no exposure to the residues of laminarin
is expected. Pesticidal applications are
applied directly to agricultural crops,
and data suggest that residues are not
PO 00000
Frm 00017
Fmt 4700
Sfmt 4700
8255
expected beyond the time of harvest.
Accordingly, little to no dietary
exposure is expected. As such, the
Agency has determined that this food
use of laminarin poses no foreseeable
risks to human health or the
environment. Thus, there is a reasonable
certainty of no harm to the general U.S.
population, including infants and
children, from exposure to this active
ingredient.
1. U.S. population. The Agency has
determined that there is a reasonable
certainty that no harm will result from
aggregate exposure to residues of
laminarin to the U.S. population. This
includes all anticipated dietary
exposures and other non-occupational
exposures for which there is reliable
information. The Agency arrived at this
conclusion based on the low levels of
mammalian dietary toxicity associated
with laminarin, the natural ubiquity of
laminarin in foodstuffs, and information
suggesting that the pesticidal use of
laminarin will not result in a significant,
if any, exposure. For these reasons, the
Agency has determined that laminarin
residues in and on all food commodities
will be safe, and that there is a
reasonable certainty that no harm will
result from aggregate exposure to
residues of laminarin.
2. Infants and children. FFDCA
section 408(b)(2)(C) provides that EPA
shall assess the available information
about consumption patterns among
infants and children, special
susceptibility of infants and children to
pesticide chemical residues, and the
cumulative effects on infants and
children of the residues and other
substances with a common mechanism
of toxicity. In addition, FFDCA section
408(b)(2)(C) provides that EPA shall
apply an additional tenfold margin of
exposure (safety) for infants and
children in the case of threshold effects
to account for prenatal and postnatal
toxicity and the completeness of the
database unless the EPA determines that
a different margin of exposure (safety)
will be safe for infants and children.
Margins of exposure (safety), which are
often referred to as uncertainty factors,
are incorporated into EPA risk
assessments either directly or through
the use of a margin of exposure analysis,
or by using uncertainty (safety) factors
in calculating a dose level that poses no
appreciable risk.
Based on all the information
evaluated for laminarin, the Agency
concludes that there are no threshold
effects of concern and, as a result, the
provision requiring an additional
margin of safety does not apply.

VII. Other Considerations
A. Endocrine Disruptors
There is no evidence, at this time, that
suggests that laminarin will compromise
the endocrine system, function in a
manner similar to any known hormone,
or act as an endocrine disruptor.
B. Analytical Method(s)
Through this action, the Agency
proposes an exemption from the
requirement of a tolerance of laminarin
when used on food commodities,
without any numerical limitations for
residues. EPA has determined that
residues resulting from the pesticidal
use of laminarin are unlikely and that
there are no significant toxicity
concerns in the event that residues of
the active ingredient are present. As a
result, the Agency has concluded that
an analytical method is not required for
enforcement purposes for laminarin.
C. Codex Maximum Residue Level
There are no codex maximum residue
levels established for residues of
laminarin.
cprice-sewell on DSK2BSOYB1PROD with RULES
VIII. Conclusions
Based on the data submitted to
support this tolerance exemption, and
other information available to the
Agency, EPA is establishing an
exemption from the tolerance
requirements, pursuant to FFDCA
section 408(c), for residues of laminarin
in or on all food commodities.
IX. Statutory and Executive Order
Reviews
This final rule establishes a tolerance
under section 408(d) of FFDCA in
response to a petition submitted to the
Agency. The Office of Management and
Budget (OMB) has exempted these types
of actions from review under Executive
Order 12866, entitled Regulatory
Planning and Review (58 FR 51735,
October 4, 1993). Because this final rule
has been exempted from review under
Executive Order 12866, this final rule is
not subject to Executive Order 13211,
entitled Actions Concerning Regulations
That Significantly Affect Energy Supply,
Distribution, or Use (66 FR 28355, May
22, 2001) or Executive Order 13045,
entitled Protection of Children from
Environmental Health Risks and Safety
Risks (62 FR 19885, April 23, 1997).
This final rule does not contain any
information collections subject to OMB
approval under the Paperwork
Reduction Act (PRA), 44 U.S.C. 3501 et
seq., nor does it require any special
considerations under Executive Order

Since tolerances and exemptions that
are established on the basis of a petition
under section 408(d) of FFDCA, such as
the tolerance in this final rule, do not
require the issuance of a proposed rule,
the requirements of the Regulatory
Flexibility Act (RFA) (5 U.S.C. 601 et
seq.) do not apply.
This final rule directly regulates
growers, food processors, food handlers,
and food retailers, not States or tribes,
nor does this action 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,
the Agency 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, the Agency 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) (Public Law 104–4).
This action does not involve any
technical standards that would require
Agency 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).
X. 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.

II. Background and Statutory Findings
In the Federal Register of July 31, 2008 (73 FR 44719) (FRL-8374-
3), 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 7E7276) by Laboratoires Go[euml]mar SA c/o SciReg, Inc.,
12733 Director's Loop, Woodbridge, VA 22192. The petition requested
that 40 CFR part 180 be amended by establishing an exemption from the
requirement of a tolerance for residues of laminarin. This notice
included a summary of the petition prepared by the petitioner
Laboratoires Go[euml]mar SA c/o SciReg, Inc. There were no comments
received in response to the notice of filing.
Section 408(c)(2)(A)(i) of FFDCA allows EPA to establish an
exemption from the requirement for a tolerance (the legal limit for a
pesticide chemical residue in or on a food) only if EPA determines that
the exemption is ``safe.'' Section 408(c)(2)(A)(ii) of FFDCA defines
``safe'' to mean that ``there is a reasonable certainty that no harm
will result from aggregate exposure to the pesticide chemical residue,
including all anticipated dietary exposures and all other exposures for
which there is reliable information.'' This includes exposure through
drinking water and in residential settings, but does not include
occupational exposure. Pursuant to section 408(c)(2)(B) of FFDCA, in
establishing or maintaining in effect an exemption from the requirement
of a tolerance, EPA must take into account the factors set forth in
section 408(b)(2)(C) of FFDCA, which require EPA to give special
consideration to exposure of infants and children to the pesticide
chemical residue in establishing a tolerance and to ``ensure that there
is a reasonable certainty that no harm will result to infants and
children from aggregate exposure to the pesticide chemical residue....
'' Additionally, section 408(b)(2)(D) of FFDCA requires that the Agency
consider ``available information concerning the cumulative effects of a
particular pesticide's residues'' and ``other substances that have a
common mechanism of toxicity.''
EPA performs a number of analyses to determine the risks from
aggregate exposure to pesticide residues. First, EPA determines the
toxicity of pesticides. Second, EPA examines exposure to the pesticide
through food, drinking water, and through other exposures that occur as
a result of pesticide use in residential settings.
III. Toxicological Profile
Consistent with section 408(b)(2)(D) of FFDCA, EPA has reviewed the
available scientific data and other relevant information in support of
this action and considered its validity, completeness, and reliability
and the relationship of this information to human risk. EPA has also
considered available information concerning the variability of the
sensitivities of major identifiable subgroups of consumers, including
infants and children.
Laminarin, a naturally occurring [beta]-glucan (polysaccharide
carbohydrate), may be extracted from many types of brown algae (e.g.,
Laminaria digitata). Generally, [beta]-glucans are major constituents
in the bran of most cereal grains and are intentionally added to many
dietary supplements and texturing agents; therefore, these
carbohydrates are typically consumed as a regular part of the human
diet. Laminarin, specifically, is an integral part of the human diet in
countries such as Ireland, France, and Japan, where Laminaria digitata
is used for sea-vegetable production. As a biochemical active
ingredient, laminarin stimulates the natural defense reactions of
agricultural crops such as fruiting vegetables, tomato, eggplant,
pepper, zucchini, cucurbits, watermelon, melons, grape, apple, pear,
and strawberries against particular disease organisms (e.g., gray mold,
powdery mildew, downy mildew, fire blight, and bacterial spot). As a
naturally occurring oligosaccharide (a carbohydrate), residues of the
active ingredient are indistinguishable from other naturally occurring
plant oligosaccharides. In addition to the extensive history of
consumption of [beta]-glucans--particularly laminarin in this case--
without documented toxicological effects, the data submitted to the
Agency, in conjunction with and in support of this tolerance exemption,
confirm that laminarin is virtually nontoxic and poses no dietary risks
to humans.
Because laminarin is considered ``toxicologically innocuous,'' no
residue studies are required to support a tolerance exemption. However,
laminarin's low toxicity profile notwithstanding, another justification
for this exemption from the requirement of a tolerance is the
unlikelihood of residues for this biochemical pesticide in or on food.
Laminarin is intended for application as a systemic acquired resistance
(SAR) inducer--a preventative mode of action. As such, it is applied
early in a crop's life cycle--in its growing stages--to help build
immunity to disease organisms such as mold and bacterial infection.
Furthermore, as a biochemical, it is prone to biodegrade rapidly. Data
indicate that the active ingredient is more than 65% biodegraded after
two weeks (Master Record Identification Number (MRID No.) 472649-54).
Calculations indicate that it would be fully biodegraded long before
any consumption would occur because the most likely final application
of the pesticide would occur early in the growing season for plants
treated with
[[Page 8254]]
this pesticide. Accordingly, no exposures beyond background levels are
expected.
Summaries of the toxicological data submitted in support of this
exemption from the requirement of a tolerance follow:
A. Acute Toxicity
Acute toxicity studies, submitted to support the registration of
the end-use product containing laminarin, confirm a low toxicity
profile and buttress the finding that this active ingredient poses no
significant human health risk with regard to new food uses. Altogether,
the acute toxicity data show virtual nontoxicity for all routes of
exposure and suggest that any dietary risks associated with this
carbohydrate would be negligible.
1. The acute oral median lethal doses (LD50s) in rats
were greater than 2,000 milligrams per kilogram (mg/kg) and confirmed
negligible toxicity through the oral route. There were no observed
toxicological effects on the test subjects in either of the two acute
oral studies submitted (MRID Nos. 472649-30 and 472649-73). Laminarin
is Toxicity Category III for acute oral toxicity.
2. The acute dermal median lethal dose (LD50) in rats
was greater than 5,000 mg/kg. These data substantiated laminarin's
relative dermal nontoxicity to the general public (MRID Nos. 472649-31
and 472649-74). Laminarin is Toxicity Category IV for acute dermal
toxicity.
3. The acute inhalation median lethal concentration
(LC50) was greater than 1.02 milligrams per liter (mg/L) in
rats and showed no significant inhalation toxicity (MRID No. 472649-
32). Laminarin is Toxicity Category III for acute inhalation toxicity.
4. A skin irritation study on rabbits indicated that laminarin was
not irritating to the skin (MRID No. 472649-34). Laminarin is Toxicity
Category IV for dermal irritiation.
5. Data indicated laminarin is not a dermal sensitizer (MRID Nos.
472649-35 and 472649-78).
Data indicate that laminarin is not acutely toxic. No toxic
endpoints were established in any of the acute toxicity studies, and no
significant toxicological effects were observed in any of the acute
toxicity studies.
B. Mutagenicity
Three mutagenicity studies, using laminarin as the test substance,
were performed. These studies are sufficient to confirm that there are
no expected dietary or non-occupational risks of mutagenicity with
regard to new food uses.
1. The Reverse Mutation Assay (MRID No. 472649-42) showed that
laminarin did not induce mutant colonies relative to control groups.
2. The In vitro Mammalian Cells in Culture Assay (MRID No. 472649-
43) demonstrated that laminarin did not damage chromosomes or the
mitotic apparatus of bone marrow cells.
3. A Bone Marrow Micronucleus Assay (MRID No. 472649-44) indicated
that no toxicity was noted in either sex at any dose up to the limit
dose of 2,000 mg/kg.
C. Subchronic Toxicity
Based on its biodegradation properties, residues of laminarin are
not expected to result in significant dietary exposure beyond the
levels expected in background dietary exposures. Nonetheless, three
subchronic oral toxicity studies satisfied the data requirements for
subchronic toxicity and indicated that laminarin has no subchronic
toxicological effect.
1. A 28-day Oral Toxicity Study (MRID No. 472649-37) found no
toxicological effects regarding mortality, clinical observations,
neurotoxicity assessment, body weight, food consumption, hematology,
clinical chemistry, organ weights, and macroscopic or microscopic
observations. The no observable effect level (NOEL) was determined to
be 1,000 milligrams per kilogram per day (mg/kg/day).
2. A 90-day Oral Toxicity Study (MRID No. 472649-38) found no
statistical difference in hematology, clinical chemistry, or urinalysis
between test subjects and the control. The NOAEL was determined to be
1,000 mg/kg/day.
3. Another 90-day Oral Toxicity Study (MRID No. 472649-39) also
found no statistical difference in hematology, clinical chemistry, or
urinalysis between test subjects and the control. The NOAEL was again
determined to be 1,000 mg/kg/day.
D. Developmental Toxicity
The data submitted to the Agency demonstrate a clear lack of
developmental toxicity and supports the Agency's conclusion that there
is no risk of developmental toxicity associated with new food uses.
Data submitted to the Agency satisfy the data requirements for
developmental toxicity and indicate that laminarin poses negligible
risk with regard to developmental toxicity.
1. A Prenatal Developmental Toxicity Study (MRID No. 472649-40)
found no significant treatment-related reproductive effects or fetal
abnormalities and established a no observable adverse effect level
(NOAEL) of 1,000 mg/kg/day.
2. A second Prenatal Developmental Toxicity Study (MRID No. 472649-
41) also found no significant treatment-related reproductive effects or
fetal abnormalities and confirmed a NOAEL of 1,000 mg/kg/day.
E. Effects on Endocrine Systems
There is no available evidence demonstrating that laminarin is an
endocrine disruptor in humans. As a result, the Agency is not requiring
information on the endocrine effects of laminarin at this time.
However, the Endocrine Disruption Screening Program (EDSP) has
established a protocol, which guides the Agency in selecting suspect
ingredients for review, and the Agency reserves the right to require
new information should the program require it. Presently, based on the
lack of exposure and the negligible toxicity profile of laminarin, no
adverse effects to the endocrine are known or expected. Overall, the
lack of evidence of endocrine disruption is consistent with laminarin's
low toxicity profile and supports this exemption from the requirement
of a tolerance.
IV. Aggregate Exposures
In examining aggregate exposure, section 408 of FFDCA directs EPA
to consider available information concerning exposures from the
pesticide residue in food and all other non-occupational exposures,
including drinking water from ground water or surface water and
exposure through pesticide use in gardens, lawns, or buildings
(residential and other indoor uses).
A. Dietary Exposure
Because of laminarin's ability to biodegrade relatively quickly and
the typical time during plant growth that it will be applied, the
Agency does not anticipate many residues being present in or on food at
the time of consumption. Moreover, any residues that are present in or
on food at the time of consumption as a result of pesticide use are
likely to be indistinguishable from naturally occurring laminarin due
to its natural occurrence and ubiquitous presence in foods and dietary
supplements. Finally, the Agency believes that it is unlikely that any
exposure to the residues of laminarin will result in dietary risks
because of the nontoxic mode of action as a SAR inducer and the
pesticide's negligible toxicity profile.
1. Food. Exposure to residues of laminarin on foods is expected to
be negligible. Data submitted to the Agency
[[Page 8255]]
show that laminarin is 65% to 71% biodegraded within two weeks, and
that it hydrolyzes very rapidly into glucose. Because applications
necessarily occur early in the growing season (due to its mode of
action as a SAR inducer), and given its short-lived presence on crops,
no significant pesticidal residues are anticipated for harvested foods.
However, in the event of exposure to residues of laminarin, no dietary
risks are anticipated. As described in Unit III., acute, subchronic,
mutagenic and developmental studies support its nontoxic profile.
Furthermore, it is already present in foods without any known
detrimental effects. Indeed, there is no information in the public
literature suggesting any health issues to either animals or plants
relative to this compound. Lastly, proposed rates of application of
laminarin will result in substantially fewer residues in or on foods as
a result of pesticide application than the quantities of laminarin
already consumed in foods and those allowed in dietary supplements. In
sum, no dietary exposure is expected; however, any potential dietary
exposures would not be expected to pose any quantifiable risk, mainly
due to laminarin's nontoxic profile.
2. Drinking water exposure. Residues of laminarin are not expected
to be present in drinking water as applications of laminarin are made
directly to terrestrial crops. Laminarin residues are not expected to
percolate through the soil because residues are not expected to persist
beyond the time it would typically take for any residues to percolate
into the groundwater. In the event of errant spray drift or
extraordinary rainfall, laminarin will not persist in water due to its
rapid hydrolyzation into glucose. Moreover, given laminarin's nontoxic
profile as described in Unit III., risks from miniscule aquatic
exposure would be negligible. Altogether, drinking water exposure is
not expected to pose any quantifiable risk due to both a lack of
residues and the nontoxicity of laminarin.
B. Other Non-Occupational Exposure
Non-occupational exposure is not expected because lamarin is not
approved for residential uses. The active ingredient is applied
directly to commodities and degrades rapidly. Furthermore, the Agency
notes that health risks are not expected from any pesticidal exposure
to this active ingredient, no matter the circumstances. An August 2009
Agency risk assessment of laminarin clearly establishes that even
prolonged and regular occupational exposures, which are associated with
this active ingredient, pose negligible risks. Laminarin is
characterized by its biodegradability, low toxicity profile, nontoxic,
SAR-inducing mode of action, and demonstrable lack of dietary effects.
1. Dermal exposure. Non-occupational dermal exposures to laminarin
are expected to be negligible because of its directed agricultural use.
Even in the event of dermal exposure to residues, the nontoxic profile
of laminarin (as described in Unit III.) is not expected to result in
any risks through this route of exposure.
2. Inhalation exposure. Non-occupational inhalation exposures are
not expected to result from the agricultural uses of laminarin. Any
inhalation exposure associated with this new agricultural use pattern
is expected to be occupational in nature.
V. Cumulative Effects
Pursuant to FFDCA section 408(b)(2)(D)(v), EPA has considered
available information concerning the cumulative effects of exposure to
laminarin residues and other substances that have a common mechanism of
toxicity. These considerations include the possible cumulative effects
of such residues on infants and children. Because laminarin operates
through a nontoxic mode of action, there is no common mechanism of
toxicity between this and any other substances; therefore, this
provision does not apply. Nevertheless, given that no exposure to
residues are expected when applications are made in accordance with
EPA-approved labeling and good agricultural practices, and laminarin
has a long history of dietary consumption without incident, the Agency
concludes that there is no reason to anticipate cumulative effects from
the residues of this active ingredient with other related pesticides.
VI. Determination of Safety for U.S. Population, Infants and Children
Health risks to humans, including infants and children, are
considered negligible with regard to the pesticidal use of laminarin.
As illustrated in Unit III., acute toxicity studies indicate that
laminarin has negligible toxicity. It is ubiquitous in nature and
present in fruits and vegetables. To date, there is no history of
toxicological incident involving its consumption and its use in food
supplements is already allowed by the United States Food and Drug
Administration. Of equal note, little to no exposure to the residues of
laminarin is expected. Pesticidal applications are applied directly to
agricultural crops, and data suggest that residues are not expected
beyond the time of harvest. Accordingly, little to no dietary exposure
is expected. As such, the Agency has determined that this food use of
laminarin poses no foreseeable risks to human health or the
environment. Thus, there is a reasonable certainty of no harm to the
general U.S. population, including infants and children, from exposure
to this active ingredient.
1. U.S. population. The Agency has determined that there is a
reasonable certainty that no harm will result from aggregate exposure
to residues of laminarin to the U.S. population. This includes all
anticipated dietary exposures and other non-occupational exposures for
which there is reliable information. The Agency arrived at this
conclusion based on the low levels of mammalian dietary toxicity
associated with laminarin, the natural ubiquity of laminarin in
foodstuffs, and information suggesting that the pesticidal use of
laminarin will not result in a significant, if any, exposure. For these
reasons, the Agency has determined that laminarin residues in and on
all food commodities will be safe, and that there is a reasonable
certainty that no harm will result from aggregate exposure to residues
of laminarin.
2. Infants and children. FFDCA section 408(b)(2)(C) provides that
EPA shall assess the available information about consumption patterns
among infants and children, special susceptibility of infants and
children to pesticide chemical residues, and the cumulative effects on
infants and children of the residues and other substances with a common
mechanism of toxicity. In addition, FFDCA section 408(b)(2)(C) provides
that EPA shall apply an additional tenfold margin of exposure (safety)
for infants and children in the case of threshold effects to account
for prenatal and postnatal toxicity and the completeness of the
database unless the EPA determines that a different margin of exposure
(safety) will be safe for infants and children. Margins of exposure
(safety), which are often referred to as uncertainty factors, are
incorporated into EPA risk assessments either directly or through the
use of a margin of exposure analysis, or by using uncertainty (safety)
factors in calculating a dose level that poses no appreciable risk.
Based on all the information evaluated for laminarin, the Agency
concludes that there are no threshold effects of concern and, as a
result, the provision requiring an additional margin of safety does not
apply.
[[Page 8256]]
VII. Other Considerations
A. Endocrine Disruptors
There is no evidence, at this time, that suggests that laminarin
will compromise the endocrine system, function in a manner similar to
any known hormone, or act as an endocrine disruptor.
B. Analytical Method(s)
Through this action, the Agency proposes an exemption from the
requirement of a tolerance of laminarin when used on food commodities,
without any numerical limitations for residues. EPA has determined that
residues resulting from the pesticidal use of laminarin are unlikely
and that there are no significant toxicity concerns in the event that
residues of the active ingredient are present. As a result, the Agency
has concluded that an analytical method is not required for enforcement
purposes for laminarin.
C. Codex Maximum Residue Level
There are no codex maximum residue levels established for residues
of laminarin.
VIII. Conclusions
Based on the data submitted to support this tolerance exemption,
and other information available to the Agency, EPA is establishing an
exemption from the tolerance requirements, pursuant to FFDCA section
408(c), for residues of laminarin in or on all food commodities.
IX. Statutory and Executive Order Reviews
This final rule establishes a tolerance under section 408(d) of
FFDCA in response to a petition submitted to the Agency. The Office of
Management and Budget (OMB) has exempted these types of actions from
review under Executive Order 12866, entitled Regulatory Planning and
Review (58 FR 51735, October 4, 1993). Because this final rule has been
exempted from review under Executive Order 12866, this final rule is
not subject to Executive Order 13211, entitled Actions Concerning
Regulations That Significantly Affect Energy Supply, Distribution, or
Use (66 FR 28355, May 22, 2001) or Executive Order 13045, entitled
Protection of Children from Environmental Health Risks and Safety Risks
(62 FR 19885, April 23, 1997). This final rule does not contain any
information collections subject to OMB approval under the Paperwork
Reduction Act (PRA), 44 U.S.C. 3501 et seq., nor does it require any
special considerations under Executive Order 12898, entitled Federal
Actions to Address Environmental Justice in Minority Populations and
Low-Income Populations (59 FR 7629, February 16, 1994).
Since tolerances and exemptions that are established on the basis
of a petition under section 408(d) of FFDCA, such as the tolerance in
this final rule, do not require the issuance of a proposed rule, the
requirements of the Regulatory Flexibility Act (RFA) (5 U.S.C. 601 et
seq.) do not apply.
This final rule directly regulates growers, food processors, food
handlers, and food retailers, not States or tribes, nor does this
action 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, the Agency 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, the Agency 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) (Public Law 104-4).
This action does not involve any technical standards that would
require Agency 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).
X. 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).
