requirements beyond those imposed by
state law. Accordingly, the
Administrator certifies that this rule
will not have a significant economic
impact on a substantial number of small
entities under the Regulatory Flexibility
Act (5 U.S.C. 601 et seq.). Because this
rule approves pre-existing requirements
under state law and does not impose
any additional enforceable duty beyond
that required by State law, it does not
contain any unfunded mandate or
significantly or uniquely affect small
governments, as described in the
Unfunded Mandates Reform Act of 1995
(Pub. L. 104–4).
This rule also does not have tribal
implications because it will not have a
substantial direct effect on one or more
Indian tribes, on the relationship
between the Federal Government and
Indian tribes, or on the distribution of
power and responsibilities between the
Federal Government and Indian tribes,
as specified by Executive Order 13175
(65 FR 67249, November 9, 2000). This
action also does not have Federalism
implications because it does not have
substantial direct effects on the States,
on the relationship between the national
government and the States, or on the
distribution of power and
responsibilities among the various
levels of government, as specified in
Executive Order 13132 (64 FR 43255,
August 10, 1999), because it merely
approves a State rule implementing a
Federal standard, and does not alter the
relationship or the distribution of power
and responsibilities established in the
Clean Air Act. This rule also is not
subject to Executive Order 13045
‘‘Protection of Children from
Environmental Health Risks and Safety
Risks’’ (62 FR 19885, April 23, 1997),
because it is not economically
significant.
In reviewing section 111(d)
submissions, EPA’s role is to approve
state plans, provided that they meet the
criteria of the Clean Air Act. In this
context, in the absence of a prior
existing requirement for the State to use
voluntary consensus standards (VCS),
EPA has no authority to disapprove a
state plan submission for failure to use
VCS. It would thus be inconsistent with
applicable law for EPA, when it reviews
a state plan submission, to use VCS in
place of a state plan submission that
otherwise satisfies the provisions of the
Clean Air Act. Thus, the requirements of
section 12(d) of the National
Technology Transfer and Advancement
Act of 1995 (15 U.S.C. 272 note) do not
apply. This rule does not impose an
information collection burden under the
provisions of the Paperwork Reduction
Act of 1995 (44 U.S.C. 3501 et seq.)

The Congressional Review Act, 5
U.S.C. 801 et seq., as added by the Small
Business Regulatory Enforcement
Fairness Act of 1996, generally provides
that before a rule may take effect, the
agency promulgating the rule must
submit a rule report, which includes a
copy of the rule, 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 the rule in
the Federal Register. A major rule
cannot take effect until 60 days after it
is published in the Federal Register.
This action is not a ‘‘major rule’’ as
defined by 5 U.S.C. 804(2).
Under section 307(b)(1) of the Clean
Air Act, petitions for judicial review of
this action must be filed in the United
States Court of Appeals for the

review, unless the objection arises after
the comment period allowed for in the
proposal. Filing a petition for
reconsideration by the Administrator of
this final rule does not affect the finality
of this rule for the purposes of judicial
review nor does it extend the time
within which a petition for judicial
review may be filed, and shall not
postpone the effectiveness of such rule

346a(d)(3), announcing the filing of a
pesticide tolerance petition PP 6E7082
by Brushy Mountain Bee farm, c/o IR4 Project Rutgers University, 681 U.S.
Highway 1 South, North Brunswick,
New Jersey 08902. The petition
requested that 40 CFR part 180 be

Frm 00013

amended by establishing an exemption
from the requirement of a tolerance for
residues of eucalyptus oil. This notice
included a summary of the petition
prepared by the petitioner Brushy
Mountain Bee farm, c/o IR-4 Project
Rutgers. There were no comments
received in response to the notice of
filing.
Section 408(c)(2)(A)(i) of the FFDCA
allows EPA to establish an exemption
6efrom 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 the 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), 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), 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 the 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 the 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.

Federal Register / Vol. 71, No. 177 / Wednesday, September 13, 2006 / Rules and Regulations
Eucalyptus oil (EO) is an essential oil
that is obtained from steam distillation
of the leaves of Eucalyptus globulus.
Eucalyptus oil has a long history of safe
medicinal uses and has been classified
by FDA as a GRAS substance and
permitted as a direct additive to foods
for human consumption (21 CFR
172.510). It is used as a component of
decongestant products, as an
expectorant component of cough and
cold products, in various oral dosages
from (e.g., lozenges and syrups), and as
an inhalant in vapor baths, etc. In 2002,
100,000 tons of Halls cough drops were
consumed. There are no incident reports
of adverse effects associated with
exposures to EO.
There is limited information in the
public literature and information
reported by the FDA that provides a
limit to the levels of EO that can be
present in foods and or medicines. One
exception however, is that EO is
currently allowed at 1.2 to 1.3% (12,000
to 13,000 mg/kg) as a topical antitussive
drug in mixtures with camphor and
menthol (21 CFR 341.14(b); 341.40(u);
341.74(b),(c),(d)). A topical antitussive
is defined as a drug that relieves cough
when inhaled after being applied
topically to the throat or chest in the
form of an ointment or from a steam
vaporizer or when dissolved in the
mouth in the form of a lozenge for a
local effect (21 CFR 341.3(c). Eucalyptus
oil can be used orally in cough drops at
162 to 2,000 mg/kg (Ref. 1). There is
information in the public literature that
EO is known to be toxic at high levels.
However, based on the most likely use
pattern for EO as a pesticide, the Agency
has determined that EO, when used as
a pesticide, will be safe because it is
likely to be used at very low levels. The
lack of information in the public
literature on the levels of EO that is
present in certain foods and medicines
is due to a lack of an available method
to detect residues of eucalyptus oil in
foods and medicines. This is primarily
due to the fact that most essential oils
from plants such a Eucalyptus spp.
contain many components and
therefore, may be difficult to
characterize the actual oil component.
Eucalyptus oil from Eucalyptus globulus
is composed eucalyptol, triterpenes,
monoterpenes, sesquiterpenes,
aldehydes and ketones of which
eucalyptol (1,8-cineole) makes up to
80% or more of EO. Since there is no
method of detection for EO in foods, the
Agency has conducted a dietary risk
assessment in order to estimate the
exposure to eucalyptus oil when used as
a pesticide in or on honey and honey
comb.

Toxicity data requirements were
satisfied by the registrant with data and/
or information from the public literature
and requests to waive toxicity testing for
the studies below. Data waiver
rationales were provided and were
acceptable and therefore data waivers
were granted by the Agency.
A. Acute and Short-term Toxicity
Information submitted by the
applicant demonstrated that acute oral
LD50 values for EO is 4,400 mg/kg body
weight in rats, 3,320 mg/kg body weight
in mice, and a dermal LD50 of > 5,000
mg/kg body weight in rabbits. These
classify EO as Toxicity Category IV for
acutely toxic oral and dermal effects. EO
is also a mild dermal irritant (Ref. 2).
Embryotoxicity and fetotoxicity were
not observed in a teratogenicity study in
which mice were dosed with EO (from
Eucalyptus globulus) subcutaneously
during days 6-15 of gestation (Ref. 1).
Acute inhalation toxicity and primary
eye irritation studies on EO were
waived because the product requires
personal protective equipment
equivalent to Toxicity Category I.
Inhalation and eye irritation only apply
to workers using the product and not to
people consuming the honey because
the EO residue levels in honey are so
low (0.125 ppm) when applied at 2g or
less EO per hive. In addition, EO has a
long history of safe use as a common
ingredient in ointments applied to the
skin and steam vaporizer solution for
the relief of cold and flu symptoms.
Hypersensitivity incidents must be
reported to the Agency. No incidents
have been reported during the last few
years when EO in combination with
other compounds has been used under
the FIFRA section 18 program to control
Varroa mites in bees.
B. Genotoxicity / Mutagenicity
Data submitted supported the waiver
request for genotoxicity. No genotoxicity
was observed following exposure of
eucalyptus oil to Salmonella strains
TA100, TA1535, TA1537, TA98 in tests
with or without activation by rat and
hamster liver S9 fractions (Ref. 3). An
additional study (Ref. 4) also reported
that eucalyptol, the main component of
eucalyptus oil, was negative for
mutation in S. typhimurium strains
TA100, TA97A, TA98, TA102 both with
and without metabolic activation (via
rat liver S-9). Other in vitro studies
show a weak positive to positive
increases in sister chromatid exchanges
were reported in Chinese hamster ovary
(CHO) cells without metabolic
activation (Ref. 5). Equivocal or weakly
positive increases in chromosome
aberrations were observed in CHO cells
PO 00000
Frm 00014
Fmt 4700
Sfmt 4700
with S9 metabolic activation (Ref. 5).
Overall, the weight of evidence suggests
that EO is not genotoxic or mutagenic.
C. Subchronic Toxicity
Oral subchronic studies are typically
required when the pesticidal use
requires a tolerance or an exemption
from the requirement of a tolerance, a
food additive regulation, or its use
results in repeated human oral
exposure. Dietary subchronic exposure
to EO in honey is probable. EO residues
are found in other food items at
significantly higher concentrations than
those resulting from pesticidal
treatments. Because the dietary
contribution of EO from honey is
expected to be negligible compared to
that already in the diet, subchronic
studies are not required.
IV. Aggregate Exposures
In examining aggregate exposure,
section 408 of the 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).
The Agency believes that establishing
a tolerance exemption for residues of
eucalyptus oil in or on honey or honey
comb will not cause any new exposure
that would not be safe. As mentioned in
Unit III., the U.S. population in general
is already exposed to EO from the
consumption of cough lozenges and
other food products at levels which are
equivalent to the limit levels for this
tolerance exemption without any
reports of adverse effects. Further, the
daily exposure to EO from honey
consumption is negligible when
compared to the level ingested for
therapeutic use. In order to validate the
determination that any new exposure
from the use of eucalyptus oil is safe,
the Agency conducted a dietary risk
assessment using magnitude of residue
data measuring eucalyptol and adjusted
by 20 percent because eucalyptol is 80
percent of EO. As a result of this risk
assessment, the Agency concludes that
the use of EO when used as a pesticide
on honey or honey comb to suppress
varroa mites when applied at 2g or less
EO will not add any new exposures or
risks and is considered safe.
A. Dietary Exposure
A dietary risk was estimated by
comparing theoretical exposures using
the EO residues approved for use by
FDA in cough drops as stated above.
E:\FR\FM\13SER1.SGM
13SER1
rmajette on PROD1PC67 with RULES1
Federal Register / Vol. 71, No. 177 / Wednesday, September 13, 2006 / Rules and Regulations
These theoretical exposures were
compared to the current consumption of
eucalyptol, the therapeutic dose of
eucalyptol. Comparisons were not
calculated for the infant population
because honey is generally not
recommended for infant consumption
due to the dangers it can pose to infants.
Before comparisons could be made,
exposures had to be put into terms of
EO, not the marker analyte eucalyptol as
described above. The amount of
eucalyptus oil allowed in cough drops
is 2,000 ppm which is 16,000 times that
found in the honey submitted residue
trial (Ref. 6).
Based on the dietary risk assessment
conducted by the Agency, it has been
determined that daily exposures to EO
from honey consumption would be
orders of magnitude less than the level
ingested for therapeutic use. Therefore,
the Agency concludes that residues of
EO in honey when applied at 2g or less
per hive are of no dietary concern to the
U.S. population including children.
1. Food. Eucalyptus oil is commonly
found in numerous food items such as
yellow cake, vanilla ice cream, cola
beverages, and caramel candy. In 2002,
people consumed 100,000 tons of Halls
drops (https://
www.cadburyschweppes.com/EN
/Brands/About/Confectionery/
factsheet_halls.htm); while in the
Northern Hemisphere these are sold as
cough drops, other parts of the world
consume them as candy. The daily
exposure to EO from honey
consumption when used at 2g or less is
orders of magnitude less than the level
ingested for therapeutic use (Ref. 1).
Therefore, residues of EO in honey are
not considered a dietary concern.
Conservative exposure estimates and the
use of lowest toxicity concentrations
ensure that residues of EO present a
reasonable certainty of no harm.
Therefore, no adverse effects associated
with exposures to EO by oral route are
expected from the use of EO as a
pesticide when used at 2g or less EO per
hive.
2. Drinking water exposure. No
exposure to EO residues in drinking
water is expected because the use of this
product is limited to application within
the hive box in which the product is
contained in a dispenser tray, where the
product is rapidly volatilized or
redistributed.
3. Magnitude of the Residue in/on
Honey and Honeycomb. The end-use
product, ApiLife VAR, has acceptable
magnitude of the residue data on
eucalyptol in honey and honeycomb
when used as a treatment for Varroa
mites in bee hives (Ref. 6; Ref. 7).
Eucalyptol is the marker analyte for EO
VerDate Aug<31>2005
15:10 Sep 12, 2006
Jkt 208001
and comprises 80% (v/v) of the original
mixture. Residue estimates and dietary
exposures estimated with eucalyptol
(0.1 mg/kg) were modified to account
for the percentage of eucalyptol in EO
(80%). Essentially, this meant
increasing these estimates by 20%
(equivalent to 0.125 mg/kg EO residues).
The dietary exposure of eucalyptol in
honey is below EPA’s levels of concern
for all population subgroups (Ref. 1).
B. Other Non-Occupational Exposure
The potential for non-dietary
exposure to EO residues for the general
population, including infants and
children, is unlikely because the
proposed use-site is limited to beehives.
V. Cumulative Effects
There is no indication that the toxic
effects of EO are cumulative. Section
408(b)(2)(D)(v) of the FFDCA requires
that, when considering whether to
establish, modify, or revoke a tolerance,
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 does not have, at this time,
available data to determine whether EO
has a common mechanism of toxicity
with other substances. Unlike other
pesticides for which EPA has followed
a cumulative risk approach based on a
common mechanism of toxicity, EPA
has not made a common mechanism of
toxicity finding as to EO and any other
substances and EO does not appear to
produce a toxic metabolite produced by
other substances. For the purposes of
this tolerance action, therefore, EPA has
not assumed that EO has a common
mechanism of toxicity with other
substances. For information regarding
EPA’s efforts to determine which
chemicals have a common mechanism
of toxicity and to evaluate the
cumulative effects of such chemicals,
see the policy statements released by
EPA’s Office of Pesticide Programs
concerning common mechanism
determinations and procedures for
cumulating effects from substances
found to have a common mechanism on
EPA’s website at https://www.epa.gov/
pesticides/cumulative.
VI. Determination of Safety for U.S.
Population, Infants and Children
There is a reasonable certainty that no
harm will result to the U.S. population
including children from aggregate
exposure to residues of EO as a result
of its use as a pesticide in or on honey
and honey comb when used at 2g or less
EO per hive since no toxicity is
expected and the U.S. population in
PO 00000
Frm 00015
Fmt 4700
Sfmt 4700
53977
general is already exposed to EO from
the consumption of cough lozenges at
much higher levels without any reports
of adverse effects. This includes all
anticipated dietary exposures and all
other exposures for which there is
reliable information. The anticipated
residues in honey are at 0.125 ppm,
which is more than 16,000 times lower
than the established acceptable level in
cough lozenges. Moreover, at high
levels, EO gives off an undesirable or ill
taste to the palate when consumed at
levels which far exceed those levels
reported for medicinal uses such as teas.
For these reasons, it is unlikely that EO
will be consumed at levels exceeding
those reported here based on the
undesirable taste alone. In addition,
there is very little potential for exposure
to EO from drinking water since the
product will volatize or exposure and is
limited to beehives or from non dietary,
non occupational exposure since its use
is limited to beehives. Therefore, based
on its long history of safe use
therapeutic and medicinal agents
without any reports of any toxic or
adverse effects and the fact that EO is
classified by FDA as a substance that is
generally recognized as safe (GRAS)
when used as a direct additive to foods
for human consumption, the Agency
believes that the health risk to humans
is negligible and concludes that there is
a reasonable certainty that no harm will
result from aggregate exposures to EO.
VII. Other Considerations
A. Endocrine Disruptors
EPA is required under section 408(p)
of the FFDCA, as amended by FQPA, to
develop a screening program to
determine whether certain substances
(including all pesticide active and other
ingredients) ‘‘may have an effect in
humans that is similar to an effect
produced by a naturally-occurring
estrogen, or other such endocrine effects
as the Administrator may designate.’’
Following the recommendations of its
Endocrine Disruptor Screening and
Testing Advisory Committee (EDSTAC),
EPA determined that there was
scientific basis for including, as part of
the program, the androgen- and thyroid
hormone systems, in addition to the
estrogen hormone system. EPA also
adopted EDSTAC’s recommendation
that the program include evaluations of
potential effects in wildlife. For
pesticide chemicals, EPA will use
FIFRA and, to the extent that effects in
wildlife may help determine whether a
substance may have an effect in
humans, FFDCA authority to require the
wildlife evaluations. As the science
develops and resources allow, screening
E:\FR\FM\13SER1.SGM
13SER1
53978
Federal Register / Vol. 71, No. 177 / Wednesday, September 13, 2006 / Rules and Regulations
of additional hormone systems may be
added to the Endocrine Disruptor
Screening Program (EDSP).
At this time, the Agency is not
requiring information on the endocrine
effects of this active ingredient, EO.
Based on the weight of the evidence of
available data and the absence of any
reports to the Agency of sensitivity or
other adverse effects, no endocrine
system related effects are identified for
EO and none is expected because of its
use. To date there is no evidence that
EO affects the immune system,
functions in a manner similar to any
known hormone, or that it acts as an
endocrine disruptor. Thus, there is no
impact via endocrine-related effects on
the Agency’s safety finding set forth in
this proposed rule to establish an
exemption from the requirement of a
tolerance for residues of EO used at 2g
or less EO per hive.
B. Analytical Method
Through this action the Agency
proposes to establish an exemption from
the requirement of a tolerance for EO on
honey and honeycomb when used at 2g
or less EO per hive to suppress varroa
mites. This decision was reached based
on the reasons stated above which
include low toxicity to mammals and
negligible exposure from the pesticidal
use of products containing EO. For the
same reasons, the Agency concludes
that an analytical method is not
required for enforcement purposes for
EO.
C. Codex Maximum Residue Level
There are no CODEX maximum
residues levels for EO.

VIII. Conclusions
Based on the data submitted and other
information available to the Agency,
there is a reasonable certainty that no
harm will result from the aggregate
exposure to residues of EO to the U.S.
population, including infants and
children, under reasonable foreseeable
circumstances, when the biochemical
pesticide EO is used in accordance with
the product label directions and at 2 g
or less eucalyptus oil per hive. This
includes all anticipated dietary
exposures and all other nonoccupational exposures for which there
is reliable information. The Agency has
arrived at this conclusion based on the
information/data submitted (and
publicly available) demonstrating
relatively low toxicity of EO. As a result,
EPA is establishing an exemption from
the tolerance requirements pursuant to
FFDCA 408(c) and (d) for residues of EO
in or on honey, honeycomb and

X. Statutory and Executive Order
Reviews
This final rule establishes an
exemption from the requirement of a
tolerance under section 408(d) of the
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 rule has been exempted
from review under Executive Order
12866 due to its lack of significance,
this rule is not subject to Executive
Order 13211, Actions Concerning
Regulations That Significantly Affect
Energy Supply, Distribution, or Use (66
FR 28355, May 22, 2001). 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., or 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). 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); or OMB review or any Agency
action under Executive Order 13045,
entitled Protection of Children from
Environmental Health Risks and Safety
Risks (62 FR 19885, April 23, 1997).
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). Since
tolerances and exemptions that are
established on the basis of a petition
under section 408(d) of the FFDCA,
such as the exemption from the
requirement of a 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. In
addition, the Agency has determined
that this action will not have a
substantial direct effect on States, on the
relationship between the national
government and the States, or on the
distribution of power and
responsibilities among the various
levels of government, as specified in
Executive Order 13132, entitled
Federalism (64 FR 43255, August 10,
1999). Executive Order 13132 requires
EPA to develop an accountable process
to ensure ‘‘meaningful and timely input
by State and local officials in the
development of regulatory policies that
have federalism implications.’’ ‘‘Policies
that have federalism implications’’ is
defined in the Executive order to
include regulations that have
‘‘substantial direct effects on the States,
on the relationship between the national
government and the States, or on the
distribution of power and
responsibilities among the various
levels of government.’’ This final rule
directly regulates growers, food
processors, food handlers and food
retailers, not States. 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 the
FFDCA. For these same reasons, the
Agency has determined that this rule
does not have any ‘‘tribal implications’’
as described in Executive Order 13175,
entitled Consultation and Coordination
with Indian Tribal Governments (65 FR
67249, November 6, 2000). Executive
Order 13175, requires EPA to develop
an accountable process to ensure
E:\FR\FM\13SER1.SGM
13SER1
Federal Register / Vol. 71, No. 177 / Wednesday, September 13, 2006 / Rules and Regulations
‘‘meaningful and timely input by tribal
officials in the development of
regulatory policies that have tribal
implications.’’ ‘‘Policies that have tribal
implications’’ is defined in the
Executive order to include regulations
that have ‘‘substantial direct effects on
one or more Indian tribes, on the
relationship between the Federal
Government and the Indian tribes, or on
the distribution of power and
responsibilities between the Federal
Government and Indian tribes.’’ This
rule will not have substantial direct
effects on tribal governments, on the
relationship between the Federal
Government and Indian tribes, or on the
distribution of power and
responsibilities between the Federal
Government and Indian tribes, as
specified in Executive Order 13175.
Thus, Executive Order 13175 does not
apply to this rule
XI. Congressional Review Act
The Congressional Review Act, 5
U.S.C. 801 et seq., as added by the Small
Business Regulatory Enforcement
Fairness Act of 1996, generally provides
that before a rule may take effect, the
agency promulgating the rule must
submit a rule report, which includes a
copy of the rule, 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 July 19, 2006 (71 FR 41018) (FRL-8077-
8), EPA issued a notice pursuant to section 408(d)(3) of the FFDCA, 21
U.S.C. 346a(d)(3), announcing the filing of a pesticide tolerance
petition PP 6E7082 by Brushy Mountain Bee farm, c/o IR-4 Project
Rutgers University, 681 U.S. Highway 1 South, North Brunswick, New
Jersey 08902. The petition requested that 40 CFR part 180 be amended by
establishing an exemption from the requirement of a tolerance for
residues of eucalyptus oil. This notice included a summary of the
petition prepared by the petitioner Brushy Mountain Bee farm, c/o IR-4
Project Rutgers. There were no comments received in response to the
notice of filing.
Section 408(c)(2)(A)(i) of the FFDCA allows EPA to establish an
exemption 6efrom 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 the 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), 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), 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 the 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 the 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.
[[Page 53976]]
Eucalyptus oil (EO) is an essential oil that is obtained from steam
distillation of the leaves of Eucalyptus globulus. Eucalyptus oil has a
long history of safe medicinal uses and has been classified by FDA as a
GRAS substance and permitted as a direct additive to foods for human
consumption (21 CFR 172.510). It is used as a component of decongestant
products, as an expectorant component of cough and cold products, in
various oral dosages from (e.g., lozenges and syrups), and as an
inhalant in vapor baths, etc. In 2002, 100,000 tons of Halls cough
drops were consumed. There are no incident reports of adverse effects
associated with exposures to EO.
There is limited information in the public literature and
information reported by the FDA that provides a limit to the levels of
EO that can be present in foods and or medicines. One exception
however, is that EO is currently allowed at 1.2 to 1.3% (12,000 to
13,000 mg/kg) as a topical antitussive drug in mixtures with camphor
and menthol (21 CFR 341.14(b); 341.40(u); 341.74(b),(c),(d)). A topical
antitussive is defined as a drug that relieves cough when inhaled after
being applied topically to the throat or chest in the form of an
ointment or from a steam vaporizer or when dissolved in the mouth in
the form of a lozenge for a local effect (21 CFR 341.3(c). Eucalyptus
oil can be used orally in cough drops at 162 to 2,000 mg/kg (Ref. 1).
There is information in the public literature that EO is known to be
toxic at high levels. However, based on the most likely use pattern for
EO as a pesticide, the Agency has determined that EO, when used as a
pesticide, will be safe because it is likely to be used at very low
levels. The lack of information in the public literature on the levels
of EO that is present in certain foods and medicines is due to a lack
of an available method to detect residues of eucalyptus oil in foods
and medicines. This is primarily due to the fact that most essential
oils from plants such a Eucalyptus spp. contain many components and
therefore, may be difficult to characterize the actual oil component.
Eucalyptus oil from Eucalyptus globulus is composed eucalyptol,
triterpenes, monoterpenes, sesquiterpenes, aldehydes and ketones of
which eucalyptol (1,8-cineole) makes up to 80% or more of EO. Since
there is no method of detection for EO in foods, the Agency has
conducted a dietary risk assessment in order to estimate the exposure
to eucalyptus oil when used as a pesticide in or on honey and honey
comb.
Toxicity data requirements were satisfied by the registrant with
data and/or information from the public literature and requests to
waive toxicity testing for the studies below. Data waiver rationales
were provided and were acceptable and therefore data waivers were
granted by the Agency.
A. Acute and Short-term Toxicity
Information submitted by the applicant demonstrated that acute oral
LD50 values for EO is 4,400 mg/kg body weight in rats, 3,320
mg/kg body weight in mice, and a dermal LD50 of > 5,000 mg/
kg body weight in rabbits. These classify EO as Toxicity Category IV
for acutely toxic oral and dermal effects. EO is also a mild dermal
irritant (Ref. 2). Embryotoxicity and fetotoxicity were not observed in
a teratogenicity study in which mice were dosed with EO (from
Eucalyptus globulus) subcutaneously during days 6-15 of gestation (Ref.
1).
Acute inhalation toxicity and primary eye irritation studies on EO
were waived because the product requires personal protective equipment
equivalent to Toxicity Category I. Inhalation and eye irritation only
apply to workers using the product and not to people consuming the
honey because the EO residue levels in honey are so low (0.125 ppm)
when applied at 2g or less EO per hive. In addition, EO has a long
history of safe use as a common ingredient in ointments applied to the
skin and steam vaporizer solution for the relief of cold and flu
symptoms. Hypersensitivity incidents must be reported to the Agency. No
incidents have been reported during the last few years when EO in
combination with other compounds has been used under the FIFRA section
18 program to control Varroa mites in bees.
B. Genotoxicity / Mutagenicity
Data submitted supported the waiver request for genotoxicity. No
genotoxicity was observed following exposure of eucalyptus oil to
Salmonella strains TA100, TA1535, TA1537, TA98 in tests with or without
activation by rat and hamster liver S9 fractions (Ref. 3). An
additional study (Ref. 4) also reported that eucalyptol, the main
component of eucalyptus oil, was negative for mutation in S.
typhimurium strains TA100, TA97A, TA98, TA102 both with and without
metabolic activation (via rat liver S-9). Other in vitro studies show a
weak positive to positive increases in sister chromatid exchanges were
reported in Chinese hamster ovary (CHO) cells without metabolic
activation (Ref. 5). Equivocal or weakly positive increases in
chromosome aberrations were observed in CHO cells with S9 metabolic
activation (Ref. 5). Overall, the weight of evidence suggests that EO
is not genotoxic or mutagenic.
C. Subchronic Toxicity
Oral subchronic studies are typically required when the pesticidal
use requires a tolerance or an exemption from the requirement of a
tolerance, a food additive regulation, or its use results in repeated
human oral exposure. Dietary subchronic exposure to EO in honey is
probable. EO residues are found in other food items at significantly
higher concentrations than those resulting from pesticidal treatments.
Because the dietary contribution of EO from honey is expected to be
negligible compared to that already in the diet, subchronic studies are
not required.
IV. Aggregate Exposures
In examining aggregate exposure, section 408 of the 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).
The Agency believes that establishing a tolerance exemption for
residues of eucalyptus oil in or on honey or honey comb will not cause
any new exposure that would not be safe. As mentioned in Unit III., the
U.S. population in general is already exposed to EO from the
consumption of cough lozenges and other food products at levels which
are equivalent to the limit levels for this tolerance exemption without
any reports of adverse effects. Further, the daily exposure to EO from
honey consumption is negligible when compared to the level ingested for
therapeutic use. In order to validate the determination that any new
exposure from the use of eucalyptus oil is safe, the Agency conducted a
dietary risk assessment using magnitude of residue data measuring
eucalyptol and adjusted by 20 percent because eucalyptol is 80 percent
of EO. As a result of this risk assessment, the Agency concludes that
the use of EO when used as a pesticide on honey or honey comb to
suppress varroa mites when applied at 2g or less EO will not add any
new exposures or risks and is considered safe.
A. Dietary Exposure
A dietary risk was estimated by comparing theoretical exposures
using the EO residues approved for use by FDA in cough drops as stated
above.
[[Page 53977]]
These theoretical exposures were compared to the current consumption of
eucalyptol, the therapeutic dose of eucalyptol. Comparisons were not
calculated for the infant population because honey is generally not
recommended for infant consumption due to the dangers it can pose to
infants. Before comparisons could be made, exposures had to be put into
terms of EO, not the marker analyte eucalyptol as described above. The
amount of eucalyptus oil allowed in cough drops is 2,000 ppm which is
16,000 times that found in the honey submitted residue trial (Ref. 6).
Based on the dietary risk assessment conducted by the Agency, it
has been determined that daily exposures to EO from honey consumption
would be orders of magnitude less than the level ingested for
therapeutic use. Therefore, the Agency concludes that residues of EO in
honey when applied at 2g or less per hive are of no dietary concern to
the U.S. population including children.
1. Food. Eucalyptus oil is commonly found in numerous food items
such as yellow cake, vanilla ice cream, cola beverages, and caramel
candy. In 2002, people consumed 100,000 tons of Halls drops (https://
www.cadburyschweppes.com/EN/Brands/About/Confectionery/factsheet_
halls.htm); while in the Northern Hemisphere these are sold as cough
drops, other parts of the world consume them as candy. The daily
exposure to EO from honey consumption when used at 2g or less is orders
of magnitude less than the level ingested for therapeutic use (Ref. 1).
Therefore, residues of EO in honey are not considered a dietary
concern. Conservative exposure estimates and the use of lowest toxicity
concentrations ensure that residues of EO present a reasonable
certainty of no harm. Therefore, no adverse effects associated with
exposures to EO by oral route are expected from the use of EO as a
pesticide when used at 2g or less EO per hive.
2. Drinking water exposure. No exposure to EO residues in drinking
water is expected because the use of this product is limited to
application within the hive box in which the product is contained in a
dispenser tray, where the product is rapidly volatilized or
redistributed.
3. Magnitude of the Residue in/on Honey and Honeycomb. The end-use
product, ApiLife VAR, has acceptable magnitude of the residue data on
eucalyptol in honey and honeycomb when used as a treatment for Varroa
mites in bee hives (Ref. 6; Ref. 7). Eucalyptol is the marker analyte
for EO and comprises 80% (v/v) of the original mixture. Residue
estimates and dietary exposures estimated with eucalyptol (0.1 mg/kg)
were modified to account for the percentage of eucalyptol in EO (80%).
Essentially, this meant increasing these estimates by 20% (equivalent
to 0.125 mg/kg EO residues). The dietary exposure of eucalyptol in
honey is below EPA's levels of concern for all population subgroups
(Ref. 1).
B. Other Non-Occupational Exposure
The potential for non-dietary exposure to EO residues for the
general population, including infants and children, is unlikely because
the proposed use-site is limited to beehives.
V. Cumulative Effects
There is no indication that the toxic effects of EO are cumulative.
Section 408(b)(2)(D)(v) of the FFDCA requires that, when considering
whether to establish, modify, or revoke a tolerance, 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 does not have, at this time, available data to determine
whether EO has a common mechanism of toxicity with other substances.
Unlike other pesticides for which EPA has followed a cumulative risk
approach based on a common mechanism of toxicity, EPA has not made a
common mechanism of toxicity finding as to EO and any other substances
and EO does not appear to produce a toxic metabolite produced by other
substances. For the purposes of this tolerance action, therefore, EPA
has not assumed that EO has a common mechanism of toxicity with other
substances. For information regarding EPA's efforts to determine which
chemicals have a common mechanism of toxicity and to evaluate the
cumulative effects of such chemicals, see the policy statements
released by EPA's Office of Pesticide Programs concerning common
mechanism determinations and procedures for cumulating effects from
substances found to have a common mechanism on EPA's website at https://
www.epa.gov/pesticides/cumulative.
VI. Determination of Safety for U.S. Population, Infants and Children
There is a reasonable certainty that no harm will result to the
U.S. population including children from aggregate exposure to residues
of EO as a result of its use as a pesticide in or on honey and honey
comb when used at 2g or less EO per hive since no toxicity is expected
and the U.S. population in general is already exposed to EO from the
consumption of cough lozenges at much higher levels without any reports
of adverse effects. This includes all anticipated dietary exposures and
all other exposures for which there is reliable information. The
anticipated residues in honey are at 0.125 ppm, which is more than
16,000 times lower than the established acceptable level in cough
lozenges. Moreover, at high levels, EO gives off an undesirable or ill
taste to the palate when consumed at levels which far exceed those
levels reported for medicinal uses such as teas. For these reasons, it
is unlikely that EO will be consumed at levels exceeding those reported
here based on the undesirable taste alone. In addition, there is very
little potential for exposure to EO from drinking water since the
product will volatize or exposure and is limited to beehives or from
non dietary, non occupational exposure since its use is limited to
beehives. Therefore, based on its long history of safe use therapeutic
and medicinal agents without any reports of any toxic or adverse
effects and the fact that EO is classified by FDA as a substance that
is generally recognized as safe (GRAS) when used as a direct additive
to foods for human consumption, the Agency believes that the health
risk to humans is negligible and concludes that there is a reasonable
certainty that no harm will result from aggregate exposures to EO.
VII. Other Considerations
A. Endocrine Disruptors
EPA is required under section 408(p) of the FFDCA, as amended by
FQPA, to develop a screening program to determine whether certain
substances (including all pesticide active and other ingredients) ``may
have an effect in humans that is similar to an effect produced by a
naturally-occurring estrogen, or other such endocrine effects as the
Administrator may designate.'' Following the recommendations of its
Endocrine Disruptor Screening and Testing Advisory Committee (EDSTAC),
EPA determined that there was scientific basis for including, as part
of the program, the androgen- and thyroid hormone systems, in addition
to the estrogen hormone system. EPA also adopted EDSTAC's
recommendation that the program include evaluations of potential
effects in wildlife. For pesticide chemicals, EPA will use FIFRA and,
to the extent that effects in wildlife may help determine whether a
substance may have an effect in humans, FFDCA authority to require the
wildlife evaluations. As the science develops and resources allow,
screening
[[Page 53978]]
of additional hormone systems may be added to the Endocrine Disruptor
Screening Program (EDSP).
At this time, the Agency is not requiring information on the
endocrine effects of this active ingredient, EO. Based on the weight of
the evidence of available data and the absence of any reports to the
Agency of sensitivity or other adverse effects, no endocrine system
related effects are identified for EO and none is expected because of
its use. To date there is no evidence that EO affects the immune
system, functions in a manner similar to any known hormone, or that it
acts as an endocrine disruptor. Thus, there is no impact via endocrine-
related effects on the Agency's safety finding set forth in this
proposed rule to establish an exemption from the requirement of a
tolerance for residues of EO used at 2g or less EO per hive.
B. Analytical Method
Through this action the Agency proposes to establish an exemption
from the requirement of a tolerance for EO on honey and honeycomb when
used at 2g or less EO per hive to suppress varroa mites. This decision
was reached based on the reasons stated above which include low
toxicity to mammals and negligible exposure from the pesticidal use of
products containing EO. For the same reasons, the Agency concludes that
an analytical method is not required for enforcement purposes for EO.
C. Codex Maximum Residue Level
There are no CODEX maximum residues levels for EO.
VIII. Conclusions
Based on the data submitted and other information available to the
Agency, there is a reasonable certainty that no harm will result from
the aggregate exposure to residues of EO to the U.S. population,
including infants and children, under reasonable foreseeable
circumstances, when the biochemical pesticide EO is used in accordance
with the product label directions and at 2 g or less eucalyptus oil per
hive. This includes all anticipated dietary exposures and all other
non-occupational exposures for which there is reliable information. The
Agency has arrived at this conclusion based on the information/data
submitted (and publicly available) demonstrating relatively low
toxicity of EO. As a result, EPA is establishing an exemption from the
tolerance requirements pursuant to FFDCA 408(c) and (d) for residues of
EO in or on honey, honeycomb and honeycomb with honey when used at 2g
or less EO per hive.

X. Statutory and Executive Order Reviews
This final rule establishes an exemption from the requirement of a
tolerance under section 408(d) of the 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 rule has been exempted from review under Executive
Order 12866 due to its lack of significance, this rule is not subject
to Executive Order 13211, Actions Concerning Regulations That
Significantly Affect Energy Supply, Distribution, or Use (66 FR 28355,
May 22, 2001). 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., or 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). 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);
or OMB review or any Agency action under Executive Order 13045,
entitled Protection of Children from Environmental Health Risks and
Safety Risks (62 FR 19885, April 23, 1997). 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). Since
tolerances and exemptions that are established on the basis of a
petition under section 408(d) of the FFDCA, such as the exemption from
the requirement of a 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. In addition,
the Agency has determined that this action will not have a substantial
direct effect on States, on the relationship between the national
government and the States, or on the distribution of power and
responsibilities among the various levels of government, as specified
in Executive Order 13132, entitled Federalism (64 FR 43255, August 10,
1999). Executive Order 13132 requires EPA to develop an accountable
process to ensure ``meaningful and timely input by State and local
officials in the development of regulatory policies that have
federalism implications.'' ``Policies that have federalism
implications'' is defined in the Executive order to include regulations
that have ``substantial direct effects on the States, on the
relationship between the national government and the States, or on the
distribution of power and responsibilities among the various levels of
government.'' This final rule directly regulates growers, food
processors, food handlers and food retailers, not States. 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 the FFDCA. For these same reasons, the Agency
has determined that this rule does not have any ``tribal implications''
as described in Executive Order 13175, entitled Consultation and
Coordination with Indian Tribal Governments (65 FR 67249, November 6,
2000). Executive Order 13175, requires EPA to develop an accountable
process to ensure
[[Page 53979]]
``meaningful and timely input by tribal officials in the development of
regulatory policies that have tribal implications.'' ``Policies that
have tribal implications'' is defined in the Executive order to include
regulations that have ``substantial direct effects on one or more
Indian tribes, on the relationship between the Federal Government and
the Indian tribes, or on the distribution of power and responsibilities
between the Federal Government and Indian tribes.'' This rule will not
have substantial direct effects on tribal governments, on the
relationship between the Federal Government and Indian tribes, or on
the distribution of power and responsibilities between the Federal
Government and Indian tribes, as specified in Executive Order 13175.
Thus, Executive Order 13175 does not apply to this rule
XI. Congressional Review Act
The Congressional Review Act, 5 U.S.C. 801 et seq., as added by the
Small Business Regulatory Enforcement Fairness Act of 1996, generally
provides that before a rule may take effect, the agency promulgating
the rule must submit a rule report, which includes a copy of the rule,
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).
