40 CFR Part 180
[OPP-2003-0002; FRL-7308-1]
Thymol and Eucalyptus Oil; Exemptions from the Requirement of a
Tolerance
AGENCY: Environmental Protection Agency (EPA).
ACTION: Final rule.
-----------------------------------------------------------------------
SUMMARY: This regulation establishes time-limited exemptions from the
requirement of a tolerance for residues of thymol and eucalyptus oil on
honey and honeycomb. This action is in response to EPA's granting of an
emergency exemption under section 18 of the Federal Insecticide,
Fungicide, and Rodenticide Act (FIFRA) authorizing use of these
pesticides in beehives. This regulation eliminates the need to
establish a maximum permissible level for residues of thymol and
eucalyptus oil in or on honey and honeycomb. These time-limited
exemptions from the requirement of a tolerance for residues of the
thymol and eucalyptus oil will expire and are revoked on June 30, 2005.
DATES: This regulation is effective June 6, 2003. Objections and
requests for hearings, identified by docket ID number OPP-2003-0002,
must be received on or before August 5, 2003.
ADDRESSES: Written objections and hearing requests may be submitted
electronically, by mail, or through hand delivery/courier. Follow the
detailed instructions as provided in Unit VII. of the SUPPLEMENTARY
INFORMATION.

II. Background and Statutory Findings
EPA, on its own initiative, in accordance with sections 408(e) and
408(l)(6) of the Federal Food, Drug, and Cosmetic Act (FFDCA), 21
U.S.C. 346a, is establishing time-limited exemptions from the
requirement of a tolerance for residues of thymol and eucalyptus oil in
or on honey and honeycomb. These time-limited exemptions from the
requirement of a tolerance for residues of the thymol and eucalyptus
oil will expire and are revoked on June 30, 2005. EPA will publish a
document in the Federal Register to remove the revoked exemptions from
the Code of Federal Regulations.
Section 408(l)(6) of the FFDCA requires EPA to establish a time-
limited tolerance or exemption from the requirement for a tolerance for
pesticide chemical residues in food that will result from the use of a
pesticide under an emergency exemption granted by EPA under section 18
of FIFRA. Such tolerances can be established without providing notice
or period for public comment. EPA does not intend for its actions on
section 18 related tolerances to set binding precedents for the
application of section 408 of the FFDCA and the new safety standard to
other tolerances and exemptions. Section 408(e) of the FFDCA allows EPA
to establish a tolerance or an exemption from the requirement of a
tolerance on its own initiative, i.e., without having received any
petition from an outside party.
Section 408(b)(2)(A)(i) of the 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 tolerance is ``safe.'' Section 408(b)(2)(A)(ii) defines ``safe'' to
mean that ``there is a reasonable certainty that no harm will result
from aggregate exposure to the pesticide
[[Page 33877]]
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. Section 408(b)(2)(C)
requires 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....''
Section 18 of the FIFRA authorizes EPA to exempt any Federal or
State agency from any provision of FIFRA, if EPA determines that
``emergency conditions exist which require such exemption.'' This
provision was not amended by the Food Quality Protection Act of 1996
(FQPA). EPA has established regulations governing such emergency
exemptions in 40 CFR part 166.
III. Emergency Exemption for Thymol and Eucalyptus Oil on Honey and
Honeycomb and FFDCA Tolerances
The varroa mite is an ectoparasite of honey bees. It was first
detected in the continental United States in Maryland in 1979, and
found in Florida and Wisconsin by 1987. Currently, it is the most
important pest of honey bee colonies. The mites feed on the hemolymph
of the developing bee larva, pupa, and adult bees. Dead or dying newly
emerged bees have malformed wings, legs, abdomens, and thoraces. Recent
anecdotal evidence suggests that bee viruses and varroa mites are
closely linked. The mites have been shown to activate some of these
viruses; causing virus outbreaks that ultimately lead to colony
mortality.
Fluvalinate is currently registered for the control of varroa
mites; however, populations of varroa mites have developed resistance
to fluvalinate. Varroa mite resistance to fluvalinate has been well
documented by the United States Department of Agriculture (USDA),
Agricultural Research Service (ARS). According to USDA, ARS many hives
treated with fluvalinate have resulted in wholesale colony losses. Due
to the destructive nature of this pest coupled with the importance of
honey bees (for honey production and pollination of numerous
agricultural crops) to the U.S. economy, it is imperative that
alternative means of controlling the varroa mite be developed.
The Agency has authorized the use of coumaphos in beehives to
control varroa mites under section 18 of FIFRA since 1999 in up to 46
states. During the 2001 use season there were limited reports of mites
resistant to coumaphos in Maine and Florida. Resistance to coumaphos in
Florida was confirmed by the USDA's Texas Bee Lab in December of 2001.
In Maine, bees are primarily imported during the growing season from
Florida. South Carolina has indicated that the beekeeping industry is
migratory in nature, especially in the coastal region of the state and
subject to the introduction of coumaphos resistant mites from Florida.
Therefore, the states have requested use of the unregistered product
ApiLife VAR, containing thymol and eucalyptus oil to control mites
resistant to coumaphos. EPA has authorized under FIFRA section 18 the
use of thymol and eucalyptus oil in beehives for control of varroa
mites in Maine, Minnesota, Mississippi, Utah, Indiana, and South
Carolina. After having reviewed the submission, EPA concurs that
emergency conditions exist for these States.
As part of its assessment of this emergency exemption, EPA assessed
the potential risks presented by residues of thymol and eucalyptus oil
in or on honey and honeycomb. In doing so, EPA considered the safety
standard in section 408(b)(2) of the FFDCA, and EPA decided that the
necessary exemptions from the requirement of a tolerance under section
408(l)(6) of the FFDCA would be consistent with the safety standard and
with FIFRA section 18. Consistent with the need to move quickly on the
emergency exemption in order to address an urgent non-routine situation
and to ensure that the resulting food is safe and lawful, EPA is
issuing these exemptions without notice and opportunity for public
comment as provided in section 408(l)(6) of the FFDCA. Although these
exemptions from the requirement of a tolerance will expire and are
revoked on June 30, 2005, under section 408(l)(5) of the FFDCA,
residues of the pesticide in the tolerance remaining in or on honey and
honeycomb after that date will not be unlawful, provided the pesticide
is applied in a manner that was lawful under FIFRA. EPA will take
action to revoke these exemptions earlier if any experience with,
scientific data on, or other relevant information on these pesticides
indicate that the residues are not safe.
Because these exemptions from the requirement of a tolerance are
being approved under emergency conditions, EPA has not made any
decisions about whether thymol and eucalyptus oil meets EPA's
registration requirements for use on honey and honeycomb or whether
permanent exemptions for this use would be appropriate. Under these
circumstances, EPA does not believe that these exemptions from the
requirement of a tolerance serve as a basis for registrations of thymol
and eucalyptus oil by a State for special local needs under FIFRA
section 24(c). Nor do these exemptions serve as the basis for any State
other than Maine and South Carolina to use these pesticides in beehives
under section 18 of FIFRA without following all provisions of EPA's
regulations implementing FIFRA section 18 as identified in 40 CFR part
166. For additional information regarding the emergency exemptions for
thymol and eucalyptus oil, contact the Agency's Registration Division
at the address provided under FOR FURTHER INFORMATION CONTACT.
IV. Aggregate Risk Assessment and Determination of Safety for Thymol
EPA performs a number of analyses to determine the risks from
aggregate exposure to pesticide residues. For further discussion of the
regulatory requirements of section 408 of the FFDCA and a complete
description of the risk assessment process, see the final rule on
Bifenthrin Pesticide Tolerances (62 FR 62961, November 26, 1997) (FRL-
5754-7).
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. EPA has sufficient data to assess the hazards of thymol
and to make a determination on aggregate exposure, consistent with
section 408(b)(2) of the FFDCA, for exemptions from the requirement of
a tolerance for residues of thymol in or on honey and honeycomb. EPA's
assessment of the dietary exposures and risks associated with
establishing these exemptions from the requirement of a tolerance
follows.
A. 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. The nature of the toxic effects caused by thymol
is discussed in this unit.
The EPA has not received nor does it have available any guideline
studies on the mammalian toxicity of thymol. Thymol is found naturally
occurring in
[[Page 33878]]
thyme herb (e.g., Thymus vulgaris, T. zygis). Thyme herb is used as a
food seasoning ingredient, and is generally recognized as a safe (GRAS)
natural seasoning by the Food and Drug Administration (FDA) (21 CFR
182.10). Thyme oil also is recognized as a GRAS essential oil by FDA
(21 CFR 182.20).
In September of 1993, the EPA issued a Reregistration Eligibility
Decision (RED) for thymol. At that time the Agency concluded that
thymol is an active ingredient that should be considered for a broad
waiver of generic data requirements. This conclusion was based on the
following information:
Thymol is a component of many non-pesticidal consumer products
currently marketed in the United States. Thymol is listed as a food
additive by the Food and Drug Administration (21 CFR 172.515; synthetic
flavoring substances and adjuvants). Thymol is rapidly degraded in the
environment to elemental constituents by normal biological, physical,
and/or chemical processes that can be reasonably expected to exist
where the pesticide is applied.... The phenols of thymol are considered
GRAS as set forth in 21 CFR 172.515 (synthetic flavoring substances and
adjuvants)....
Thymol toxicity data reported available literature cite acute oral
LD50 values as 980 milligrams/kilogram (mg/kg) and 880 mg/kg
for the rat and guinea pig, respectively (Sax, 1984). The acute oral
toxicity reported for the rat and guinea pig, respectively corresponds
to Toxicity Category III. The Material Safety Data Sheet (MSDS) for the
manufacture of technical grade thymol cites human health effects as
irritating when exposed by inhalation, dermal or eye contact. The MSDS
also estimates a human ingestion LD50 at 2 grams of the
synthetic thymol. Based upon an estimated thymol dermal toxicity
LD50 of greater than 2,000 mg/kg, the dermal toxicity would
be Toxicity Category III. (Refer to pages 6 and 7 of the RED)
A summary of the submitted information on thymol toxicity allows
for the statements that the acute oral LD50 in the rat is
980 mg/kg and in the mouse is 640 to 1,800 mg/kg. Thymol is corrosive
to the rabbit eye and skin, and is not reported as a dermal sensitizer
in the guinea pig. Thymol is readily absorbed from the gastrointestinal
tract and is essentially excreted in the urine as a glucuronate and
sulfate conjugate of the parent compound. Dosing of rats with thymol in
the feed at 667 mg/kg body weight/day (highest dose tested) for 19
weeks did not produce any harmful effects. Thymol is not mutagenic in
Salmonella, but gives statistically significant positive results in an
Unscheduled DNA synthesis and Sister Chromatid Exchange tests, and in a
cell transformation test with Syrian hamster embryonic cells. Multiple
malformations are noted when thymol is injected into the air bubble or
yolk sac of embryonic chickens.
B. Exposure Assessment
In examining aggregate exposure, FFDCA section 408 directs EPA to
consider available information concerning exposures from the pesticide
residue in food and all other non-occupational exposures, including
drinking water from ground water or surface water and exposure through
pesticide use in gardens, lawns, or buildings (residential and other
indoor uses).
1. Dietary exposure--i. Food. Thymol is found naturally occurring
in thyme herb (e.g., Thymus vulgaris, T. zygis). Thyme herb is used as
a food seasoning ingredient, and is generally recognized as a safe
(GRAS) natural seasoning by FDA (21 CFR 182.10). Thyme oil also is
recognized as a GRAS essential oil by FDA (21 CFR 182.20). The volatile
oil component of thyme herb is about 2% to 5% content, and thyme oil is
reported to contain from 30% to 75% thymol, and even up to 90%. Thymol
may be safely used in foods as a synthetic flavoring substance when
used in the minimum quantity to produce the intended effect (21 CFR
172.515). Levels of thymol reported in foods where it is permitted as a
direct food additive have been stated as 44 ppm in ice cream, ices,
etc.; 2.5 ppm to 11 ppm in non-alcoholic beverages; 9.4 ppm in candy, 5
ppm to 6.5 ppm in baked goods, and 100 ppm in chewing gum. Thymol is a
natural component of lime blossom honey, where the maximum thymol
content has been determined to be 0.16 mg/kg.
Studies in Europe showed that when ApiLife Var was used for 8 weeks
in the autumn over 1 to 5 years the maximum thymol residue observed was
0.48 mg/kg. The average (median) residue value for thymol was 0.16 mg/
kg in honey. When export and import tonnage values of honey are taken
into consideration with U.S. honey production, the average yearly per
capita intake of honey is about 2 pounds, roughly equivalent to 1 kg.
If all the honey contained 0.5 mg/kg thymol then the per capita intake
of thymol would be about 1.4 [mu]g/day. For a 60 kg adult the chronic
exposure value is about 0.022 [mu]g/kg body weight/day. If a 60 kg
adult consumed 1 kg of honey containing 0.5 mg thymol in 90 days the
subchronic dietary exposure to thymol would be about 2 [mu]g/kg body
weight/day. Even if all 2 kg of the thymol-containing honey were
consumed in one sitting, the acute exposure to thymol still would be as
low as 83 [mu]g.
2. Drinking water exposure. No drinking water exposure is expected
from the pesticidal use of thymol which is confined to placement in
beehives. Thymol is currently registered for use on ornamental plants,
shrubs and grasses so there is some potential for exposure to water.
However, thymol is a constituent of a mixture of organic compounds
known to be rapidly degraded in the environment to elemental compounds
by normal biological, physical and/or chemical processes. In the RED,
the Agency concluded that the registered uses of thymol will result in
negligible exposure of the environment and nontarget organisms (refer
to page 7 of the RED). Therefore, thymol is not expected to be found in
drinking water.
3. Other non-occupational exposure. The potential for non-dietary
exposure to thymol residues for the general population, including
infants and children, is unlikely because the proposed use site is
limited to beehives. Thymol is a normal constituent of the human diet,
as a component of thyme and thyme oil, and as a direct food additive.
Therefore, while there exists a great likelihood of prior exposure for
most, if not all individuals to thymol, any increased exposure due to
the proposed use would be negligible. Thyme, which contains thymol, is
a pesticide active ingredient for the control of aphids on ornamental
plants. Thyme and thyme oil are considered minimum risk pesticides, and
are exempted as active ingredients under FIFRA [40 CFR 152.25(g)].
4. Cumulative exposure to substances with a common mechanism of
toxicity. Section 408(b)(2)(D)(v) of the FFDCA requires that, when
considering whether to establish, modify, or revoke a tolerance, the
Agency consider ``available information'' concerning the cumulative
effects of a particular pesticide's residues and ``other substances
that have a common mechanism of toxicity.''
EPA does not have, at this time, available data to determine
whether thymol has a common mechanism of toxicity with other substances
or how to include this pesticide in a cumulative risk assessment.
Unlike other pesticides for which EPA has followed a cumulative risk
approach based on a common mechanism of toxicity, thymol does not
appear to produce a toxic metabolite produced by other substances. For
the purposes of this exemption from the requirement of a tolerance,
therefore, EPA has not
[[Page 33879]]
assumed that thymol 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 final rule for Bifenthrin
Pesticide Tolerances (62 FR 62961, November 26, 1997).
C. Aggregate Risks and Determination of Safety for U.S. Population,
Infants and Children
The dietary exposure to residues of thymol to the U. S. population
from use of ApiLife Var is not likely to add significantly to current
dietary exposure to thymol. For instance, thymol has been measured in
chewing gum at 100 mg/kg, in candy at 9.4 mg/kg, and in ice cream at 44
mg/kg. These values respectively are 200-, 20-, and 100-fold greater
than the highest level of thymol (i.e., 0.48 mg/kg) measured in honey
treated with ApiLife Var. In addition, thymol as measured in ice cream
is about 300-fold higher than the average residue level of thymol
(i.e., 0.16 mg/kg) in hives treated with ApiLife Var. Additionally, it
is typical for language to appear on labels of honey that states ``Do
not feed to infants under 1 year,'' so there likely would be no
exposure of this population to residues of thymol in the honey. Older
children likely have been exposed to thymol residues from consumption
of candy, ice cream, and baked goods. Consumption of honey from hives
treated with ApiLife Var is unlikely to significantly increase exposure
to thymol. Therefore, based on the long history of use of thyme, thyme
oil, and thymol in the diet with no known adverse effects, it is
reasonable to conclude that no harm will result from exposure to thymol
in honey from beehives treated with ApiLife Var. Accordingly, EPA finds
that exempting thymol from the requirement of a tolerance will be safe.
V. Aggregate Risk Assessment and Determination of Safety for Eucalyptus
Oil
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. EPA has sufficient data to assess the hazards of
eucalyptus oil and to make a determination on aggregate exposure,
consistent with section 408(b)(2) of the FFDCA, for exemptions from the
requirement of a tolerance for residues of eucalyptus oil in or on
honey and honeycomb. EPA's assessment of the dietary exposures and
risks associated with establishing these exemptions from the
requirement of a tolerance follows.
A. 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. The nature of the toxic effects caused by
eucalyptus oil is discussed in this unit.
The EPA has not received nor does it have available any guideline
studies on the mammalian toxicity of eucalyptus oil. Eucalyptus oil is
obtained from steam distillation of the leaves of Eucalyptus globulus
and, in addition to cineole, contains triterpenes, monoterpenes,
sesquiterpenes, aldehydes and ketones. Information submitted by the
applicant allows for the statements that acute oral LD50
value for eucalyptus oil in rats is 2,480 mg/kg. Eucalyptol (1,8-
cineole) which makes up 70% or more of eucalyptus oil may be safely
used in foods as a synthetic flavoring substance when used in the
minimum quantity to produce the intended effect (21 CFR 172.515).
Eucalyptus globulus leaves also may safely be used in foods (21 CFR
172.510).
B. Exposure Assessment
In examining aggregate exposure, FFDCA section 408 directs EPA to
consider available information concerning exposures from the pesticide
residue in food and all other non-occupational exposures, including
drinking water from ground water or surface water and exposure through
pesticide use in gardens, lawns, or buildings (residential and other
indoor uses).
1. Dietary exposure.--i. Food. Eucalyptus oil is obtained from
steam distillation of the leaves of Eucalyptus globulus and, in
addition to cineole, contains triterpenes, monoterpenes,
sesquiterpenes, aldehydes and ketones. Levels of eucalyptus oil
reported in foods where it is permitted as a direct food additive have
been stated as 0.5 to 50 ppm in ice cream, ices etc.; 1.7 ppm in non-
alcoholic beverages; 1.0 ppm in alcoholic beverages; 130 ppm in candy;
and 76 ppm in baked goods. Cineole in foods has been reported at 0.13
ppm in non-alcoholic beverages; 0.50 ppm in ice cream, ices, etc.; 15
ppm in candy; 0.5 to 4.0 ppm in baked goods, and 190 ppm in chewing
gum.
Studies in Europe showed that when ApiLife Var was used for 8 weeks
in the autumn over 1 to 5 years, residues of eucalyptus oil (measured
as 1,8-cineole) were less than the limit of detection, i.e., <0.01 ppm.
ii. Drinking water exposure. No drinking water exposure is expected
from the pesticidal use of eucalyptus oil which is confined to
placement in beehives. Further, there are no products registered that
will result in exposure to drinking water. Therefore, eucalyptus oil is
not expected to found in drinking water.
2. Other non-occupational exposure. The potential for non-dietary
exposure to eucalyptus oil residues for the general population,
including infants and children, is unlikely because the proposed use-
site is limited to beehives. Eucalyptus oil is a constituent of the
human diet as a direct food additive. Eucalyptus oil is used as a
component of decongestant products, as an expectorant component of
cough and cold products, in various oral dosage forms (e.g., lozenges
and syrups), and as an inhalant in vapor baths. It is used in dermally
applied products for burns, blisters, and for muscle and joint aches.
It may be a component of toothpaste, soaps, detergents and toiletries.
It is reported to be used internally at 0.3 to 0.6 grams/day, and
externally at 5% to 20% in paraffin, jelly, or vegetable oil bases. Oil
of eucalyptus has antimicrobial properties, and has been registered as
an active pesticide ingredient in an herbal flea collar pet product
(active ingredient is in the product at 1.00%).
3. Cumulative exposure to substances with a common mechanism of
toxicity. Section 408(b)(2)(D)(v) of the FFDCA requires that, when
considering whether to establish, modify, or revoke a tolerance, the
Agency consider ``available information'' concerning the cumulative
effects of a particular pesticide's residues and ``other substances
that have a common mechanism of toxicity.''
EPA does not have, at this time, available data to determine
whether eucalyptus oil has a common mechanism of toxicity with other
substances or how to include this pesticide in a cumulative risk
assessment. Unlike other pesticides for which EPA has followed a
cumulative risk approach based on a common mechanism of toxicity,
eucalyptus oil does not appear to produce a toxic metabolite produced
by other substances. For the purposes of this exemption from the
requirement of a
[[Page 33880]]
tolerance, therefore, EPA has not assumed that eucalyptus oil 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 final rule for Bifenthrin Pesticide Tolerances (62
FR 62961, November 26, 1997).
C. Aggregate Risks and Determination of Safety for U.S. Population,
Infants and Children
The dietary exposure to residues of eucalyptus oil to the U.S.
population from use of ApiLife Var is not likely to add significantly
to current dietary exposure to eucalyptus oil. This is because no
residues of eucalyptus oil were detectable (i.e., <0.01 ppm; measured
as 1,8-cineole) when ApiLife was used in hives in the autumn in Europe
for up to 5 years. Even if oil of eucalyptus residues were found in
honey from hives treated with Apilife Var, they would have to be
present at 5,000 times greater than the limit of detection to reach the
level reported in ice cream (i.e., 50 mg/kg) and 170 times greater than
the limit of detection to reach the level reported in non-alcoholic
beverages (i.e., 1.7 mg/kg). Therefore, based on the long history of
use of eucalyptus oil in the diet with no known adverse effect, coupled
with the expectation of no to minimal residues from use of ApiLife Var
in hives, it is reasonable to conclude that no harm will result from
this pesticidal use. Accordingly, EPA finds that exempting eucalyptus
oil from the requirement of a tolerance will be safe.
VI. Other Considerations
A. Analytical Enforcement Methodology
The Agency has not reviewed the method, nor its accuracy or
reliability, used to previously analyze thymol and eucalyptus oil
residues in honey; nor has it confirmed that prior use of ApiLife Var
in European hives will give equivalent residues in hives in the United
States. However, review of information submitted on a gas
chromatographic method of analysis to measure thymol and eucalyptus oil
in European hives, and the similarity of the European hives to U.S.
hives allow for the conclusion that thymol and eucalyptus oil residues
in honey from these hives will not be significantly greater, provided
ApiLife Var is applied at the same rates to overwintering hives in the
United States as was done previously in Europe.
The method may be requested from: Barbara Madden, Registration
Division (7505C), Office of Pesticide Programs, Environmental
Protection Agency, 1200 Pennsylvania Ave., NW., Washington, DC 20460-
0001; telephone number:(703) 305-6463; e-mail address:
[email protected].
B. International Residue Limits
No Codex Maximum Residue Levels (MRL) are established for thymol.
However, Switzerland has established an MRL of 0.8 mg/kg, apparently
not from a safety finding, but rather arising from legislation that
prohibits foreign odors or tastes in honey. According to the World
Health Organization, thymol residues in food are safe to consumers at
up to 50 mg/kg. According to European Union regulation Nr. 2377/90,
thymol is in group II of the non-toxic veterinary drugs which do not
require a MRL. No Codex Maximum Residue Levels (MRL) are established
for eucalyptus oil.
VII. Conclusion
Therefore, time-limited exemptions from the requirement of a
tolerance are established for residues of thymol and eucalyptus oil in
or on honey and honeycomb.
VIII. Objections and Hearing Requests
Under section 408(g) of the FFDCA, as amended by the FQPA, any
person may file an objection to any aspect of this regulation and may
also request a hearing on those objections. The EPA procedural
regulations which govern the submission of objections and requests for
hearings appear in 40 CFR part 178. Although the procedures in those
regulations require some modification to reflect the amendments made to
the FFDCA by the FQPA, EPA will continue to use those procedures, with
appropriate adjustments, until the necessary modifications can be made.
The new section 408(g) of the FFDCA provides essentially the same
process for persons to ``object'' to a regulation for an exemption from
the requirement of a tolerance issued by EPA under new section 408(d)
of the FFDCA, as was provided in the old sections 408 and 409 of the
FFDCA. However, the period for filing objections is now 60 days, rather
than 30 days.
A. What Do I Need to Do to File an Objection or Request a Hearing?
You must file your objection or request a hearing on this
regulation in accordance with the instructions provided in this unit
and in 40 CFR part 178. To ensure proper receipt by EPA, you must
identify docket ID number OPP-2003-0002 in the subject line on the
first page of your submission. All requests must be in writing, and
must be mailed or delivered to the Hearing Clerk on or before August 5,
2003.
1. Filing the request. Your objection must specify the specific
provisions in the regulation that you object to, and the grounds for
the objections (40 CFR 178.25). If a hearing is requested, the
objections must include a statement of the factual issues(s) on which a
hearing is requested, the requestor's contentions on such issues, and a
summary of any evidence relied upon by the objector (40 CFR 178.27).
Information submitted in connection with an objection or hearing
request may be claimed confidential by marking any part or all of that
information as CBI. Information so marked will not be disclosed except
in accordance with procedures set forth in 40 CFR part 2. A copy of the
information that does not contain CBI must be submitted for inclusion
in the public record. Information not marked confidential may be
disclosed publicly by EPA without prior notice.
Mail your written request to: Office of the Hearing Clerk (1900C),
Environmental Protection Agency, 1200 Pennsylvania Ave., NW.,
Washington, DC 20460-0001. You may also deliver your request to the
Office of the Hearing Clerk in Rm.104, Crystal Mall 2, 1921
Jefferson Davis Hwy., Arlington, VA. The Office of the Hearing Clerk is
open from 8 a.m. to 4 p.m., Monday through Friday, excluding legal
holidays. The telephone number for the Office of the Hearing Clerk is
(703) 603-0061.
2. Tolerance fee payment. If you file an objection or request a
hearing, you must also pay the fee prescribed by 40 CFR 180.33(i) or
request a waiver of that fee pursuant to 40 CFR 180.33(m). You must
mail the fee to: EPA Headquarters Accounting Operations Branch, Office
of Pesticide Programs, P.O. Box 360277M, Pittsburgh, PA 15251. Please
identify the fee submission by labeling it ``Tolerance Petition Fees.''
EPA is authorized to waive any fee requirement ``when in the
judgement of the Administrator such a waiver or refund is equitable and
not contrary to the purpose of this subsection.'' For additional
information regarding the waiver of these fees, you may contact James
Tompkins by phone at (703) 305-5697, by e-mail at [email protected],
or by mailing a request for information to Mr. Tompkins at Registration
Division (7505C), Office of Pesticide Programs, Environmental
Protection Agency, 1200 Pennsylvania Ave., NW., Washington, DC 20460-
0001.

If you would like to request a waiver of the tolerance objection
fees, you must mail your request for such a waiver to: James Hollins,
Information Resources and Services Division (7502C), Office of
Pesticide Programs, Environmental Protection Agency, 1200 Pennsylvania
Ave., NW., Washington, DC 20460-0001.
3. Copies for the Docket. In addition to filing an objection or
hearing request with the Hearing Clerk as described in Unit VII.A., you
should also send a copy of your request to the PIRIB for its inclusion
in the official record that is described in Unit I.B.1. Mail your
copies, identified by the docket ID number OPP-2003-0002, to: Public
Information and Records Integrity Branch, Information Resources and
Services Division (7502C), Office of Pesticide Programs, Environmental
Protection Agency, 1200 Pennsylvania Ave., NW., Washington, DC 20460-
0001. In person or by courier, bring a copy to the location of the
PIRIB described in Unit I.B.1. You may also send an electronic copy of
your request via e-mail to: [email protected]. Please use an ASCII
file format and avoid the use of special characters and any form of
encryption. Copies of electronic objections and hearing requests will
also be accepted on disks in WordPerfect 6.1/8.0 or ASCII file format.
Do not include any CBI in your electronic copy. You may also submit an
electronic copy of your request at many Federal Depository Libraries.
B. When Will the Agency Grant a Request for a Hearing?
A request for a hearing will be granted if the Administrator
determines that the material submitted shows the following: There is a
genuine and substantial issue of fact; there is a reasonable
possibility that available evidence identified by the requestor would,
if established, resolve one or more of such issues in favor of the
requestor, taking into account uncontested claims or facts to the
contrary; and resolution of the factual issues(s) in the manner sought
by the requestor would be adequate to justify the action requested (40
CFR 178.32).
IX. Statutory and Executive Order Reviews
This final rule establishes a time-limited exemption from the
tolerance requirement under section 408 of the FFDCA. 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 FIFRA
section 18 exemption under section 408 of the FFDCA, such as the
exemption in this final rule, do not require the issuance of a proposed
rule, the requirements of the Regulatory Flexibility Act (RFA) (5
U.S.C. 601 et seq.) do not apply. 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 ``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.
X. 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).
