II. Background and Statutory Findings
EPA, on its own initiative, in
accordance with sections 408(e) and
408(l)(6) of FFDCA, 21 U.S.C. 346a(e)
and 346a(1)(6), is establishing a timelimited tolerance for residues of sulfur
dioxide, including its metabolites and
degradates (determined by measuring
only sulfur dioxide (SO2)), at 10 ppm.
This time-limited tolerance is effective
until December 31, 2014.
Section 408(l)(6) of 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
E:\FR\FM\14SER1.SGM
14SER1
Federal Register / Vol. 76, No. 178 / Wednesday, September 14, 2011 / Rules and Regulations
tkelley on DSKG8SOYB1PROD with RULES
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 FIFRA section 18 related
time-limited tolerances to set binding
precedents for the application of section
408 of FFDCA and the safety standard
to other tolerances and exemptions.
Section 408(e) of 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 FFDCA
allows EPA to establish 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) of FFDCA
defines ‘‘safe’’ to mean that ‘‘there is a
reasonable certainty that no harm will
result from aggregate exposure to the
pesticide chemical residue, including
all anticipated dietary exposures and all
other exposures for which there is
reliable information.’’ This includes
exposure through drinking water and in
residential settings, but does not include
occupational exposure. Section
408(b)(2)(C) of FFDCA 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 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.’’
EPA has established regulations
governing such emergency exemptions
in 40 CFR part 166.
III. Emergency Exemption for Sulfur
Dioxide on Figs and FFDCA Tolerances
Excessive rain and humidity at
flowering and early fruit development
in the spring are critical factors in
development of gray mold caused by
Botrytis cinerea (B. cinerea) and these
have been high in the areas where
California figs are grown over the past
two years. California estimated that gray
mold could be responsible for a 24%
yield loss; and there are no pre or postharvest fungicides registered to control
B. cinerea on fresh figs.
The Applicant asserts that an
emergency condition exists in
accordance with the criteria for
approval of an emergency exemption,
and has utilized a crisis exemption
VerDate Mar<15>2010
13:34 Sep 13, 2011
Jkt 223001
under FIFRA section 18 to allow the use
of sulfur dioxide on figs for control of
gray mold caused by B. cinerea in
California. After having reviewed the
submission, EPA concurs that an
emergency condition exists.
As part of its evaluation of the
emergency exemption application, EPA
assessed the potential risks presented by
residues of sulfur dioxide in or on fig.
In doing so, EPA considered the safety
standard in section 408(b)(2) of FFDCA,
and EPA decided that the necessary
tolerance under section 408(l)(6) of
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
this tolerance without notice and
opportunity for public comment as
provided in section 408(l)(6) of FFDCA.
Although these time-limited tolerances
expire on December 31, 2014, under
section 408(l)(5) of FFDCA, residues of
the pesticide not in excess of the
amounts specified in the tolerance
remaining in or on figs after that date
will not be unlawful, provided the
pesticide was applied in a manner that
was lawful under FIFRA, and the
residues do not exceed a level that was
authorized by this time-limited
tolerance at the time of that application.
EPA will take action to revoke this timelimited tolerance earlier if any
experience with, scientific data on, or
other relevant information on this
pesticide indicate that the residues are
not safe.
Because this time-limited tolerance is
being approved under emergency
conditions, EPA has not made any
decisions about whether sulfur dioxide
meets FIFRA’s registration requirements
for use on fig or whether a permanent
tolerance for this use would be
appropriate. Under these circumstances,
EPA does not believe that this timelimited tolerance decision serves as a
basis for registration of sulfur dioxide by
a State for special local needs under
FIFRA section 24(c). Nor does this
tolerance by itself serve as the authority
for persons in any State other than
California to use this pesticide on the
applicable crops under FIFRA section
18 absent the issuance of an emergency
exemption applicable within that State.

emergency exemption for sulfur
dioxide, contact the Agency’s
Registration Division at the address

INFORMATION CONTACT.

IV. Aggregate Risk Assessment and
Determination of Safety
Section 408(b)(2)(A)(i) of FFDCA
allows EPA to establish 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) of FFDCA
defines ‘‘safe’’ to mean that ‘‘there is a
reasonable certainty that no harm will
result from aggregate exposure to the
pesticide 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) of FFDCA 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. * * *’’
Consistent with the factors specified
in FFDCA section 408(b)(2)(D), 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 sulfite sensitive individuals,
infants and children. EPA has sufficient
data to assess the hazards of and to
make a determination on aggregate
exposure expected as a result of this
emergency exemption request and the
time-limited tolerances for residues of
sulfur dioxide, including its metabolites
and degradates (determined by
measuring only sulfur dioxide (SO2)), at
10 ppm. EPA’s assessment of exposures
and risks associated with establishing
time-limited tolerances 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,
and infants and children, as well as
sulfite sensitive individuals.

Federal Register / Vol. 76, No. 178 / Wednesday, September 14, 2011 / Rules and Regulations
International Agency for Research on
Cancer (IARC), and the Agency for
Toxic Substances and Disease Registry
(ATSDR) were relied upon for the safety
finding for sulfur dioxide made in the
May 2007 RED assessment on inorganic
sulfites, which includes the chemicals
sulfur dioxide and sodium metabisulfite
(end-use inorganic sulfite products
contain sulfur dioxide at 99.9 to 100%,
and sodium metabisulfite at 37.5 to
98.5%. These assessments are based on
peer-reviewed evaluations performed by
the Cosmetic Ingredient Review (a
program established in 1976 by the
Cosmetic, Toiletry & Fragrance
Association, now known as the Personal
Care Products Council (PCPC), with the
support of the U.S. Food and Drug
Administration (FDA) and the
Consumer Federation of America (CFA);
the Organization for Economic
Cooperation and DevelopmentScreening Information Data Set and
from other open literature sources.
People may be exposed to small
amounts of sulfur through the food
supply. However, since sulfur does not
cause any relevant toxic effects, no
quantitative dietary risk assessment is
needed. Short-term studies show that
sulfur is of very low acute oral toxicity
and does not irritate the skin (it has
been placed in Toxicity Category IV, the
least toxic category, for these effects).
Sulfur dioxide (21 CFR 182.3862) is
listed as Generally Recognized as Safe
(GRAS) by the FDA as a preservative in
certain foods. The Select Committee on
GRAS Substances (a committee of
qualified scientists contracted by FDA
to review and evaluate the safety of
GRAS substances) concluded that:
‘‘There is no evidence in the available
information on sulfur dioxide that
demonstrates, or suggests reasonable
grounds to suspect, a hazard to the
public when used at levels that are now
current and in the manner now
practiced.’’ This conclusion was based
on the knowledge that orally
administered sulfite is very rapidly
oxidized to sulfate in all species
studied. The metabolic removal of
sulfite appears to be the critical defense
mechanism. The WHO has emphasized
the use of appropriate labeling for
alerting individuals who cannot tolerate
sulfites. After receiving and reviewing
reports of adverse reactions in certain
individuals following ingestion of
sulfiting agents used as preservatives in
food products, beverages, and fresh
fruits and vegetables, the FDA requires
ingredient labels to list sulfite
concentrations in excess of 10 ppm.
Several regulatory endpoints and
standards for ambient air concentrations
VerDate Mar<15>2010
13:34 Sep 13, 2011
Jkt 223001
of sulfur dioxide have been established
at the state, Federal and international
levels. The endpoint selected by the
Agency for the bystander inhalation risk
assessment is 0.25 ppm sulfur dioxide,
with one-hour exposure duration. The
0.25 ppm concentration is based on an
ambient air quality standard set by the
California Air Resources Board. This
endpoint is deemed most applicable to
this exposure scenario, as it is based on
effects of concern for bystanders (such
as bronchoconstriction, shortness of
breath, wheezing, and chest tightness
during physical activity in persons with
asthma).
B. Exposure Assessment
1. Dietary exposure from food and
feed uses. In evaluating dietary
exposure to sulfur dioxide, EPA
considered exposure under the timelimited tolerances established by this
action, as well as all existing sulfur
dioxide tolerances in 40 CFR 180.444.
Exposures to sulfites when used as an
active or inert pesticide ingredient are
minimal because it is known to be
readily biodegradable, quickly oxidized,
and rapidly excreted from the body. In
addition, sulfur dioxide (21 CFR
182.3862) is listed as GRAS by the FDA,
with limitations, as a food preservative.
As such, sulfites are found in many
foods, primarily as a result of the GRAS
preservative use. It is estimated that
sulfite concentrations of >100 ppm may
be found in dried fruits (excluding dark
raisins and prunes), lemon and lime
juices, wine, molasses, and sauerkraut
juice. Dried potatoes, grape juice, wine
vinegar, gravies, fruit topping, and
maraschino cherries may contain
between 50 and 100 ppm sulfur dioxide.
Foods containing between 10 ppm and
50 ppm include pectin, fresh shrimp,
corn syrup, sauerkraut, pickled foods,
corn starch, hominy, frozen potatoes,
maple syrup, imported jams and jellies,
and fresh mushrooms (CIR 2003).
Preliminary data developed by the
Interregional Research Project No. 4 (IR–
4) from the concluded experimental
phase of a study now being conducted
on figs was submitted with this
exemption request. The design of the
IR–4 study is sufficient in its scope
having followed the protocol put
forward for determining the magnitude
of the residue on fresh figs from the use
of sulfur dioxide. This study shows that
following application made at a 10x
exaggerated rate of 250 ppm sulfur
dioxide/hour, samples analyzed from 1
hour up to 28 days after treatment were
all found to have residue levels of sulfur
dioxide below the limit of detection
(LOD) of 10 ppm. In view of the data
provided by IR–4, a linear extrapolation
PO 00000
Frm 00012
Fmt 4700
Sfmt 4700
from the 10x exaggerated rate to a 1x
application rate determined that a 1x
rate is likely to result in residue levels
of sulfur dioxide of 2.5 ppm or lower
when following the use-pattern in this
crisis exemption.
2. Drinking water exposure. Based on
environmental fate information for
sulfur dioxide and the requested postharvest use pattern (in closed
chambers), concentrations of concern
are not expected in drinking water.
3. Inhalation exposure. Based on the
Probabilistic Exposure and Risk Model
for Fumigants, version 2.1.1 (PERFUM2)
the requested use is expected to limit
bystander exposure potential to sulfur
dioxide concentrations at or below 0.25
ppm. This bystander exposure scenario
is considered ‘‘worst-case,’’ in that it
assumes the ventilation stack is at the
edge of the treatment warehouse, and
the warehouse is in close proximity to
the fumigation facility property line.
4. Other non-occupational exposure.
In examining aggregate exposure,
section 408 of FFDCA directs EPA to
consider available information
concerning exposures from the pesticide
residue in food and all other nonoccupational exposures, including
drinking water from ground water or
surface water and exposure through
pesticide use in gardens, lawns, or
buildings (residential and other indoor
uses). Currently there are no residential
uses for sulfur dioxide, as the use of
inorganic sulfites is limited to
postharvest fumigation of grapes.
Environmental sources of sulfur dioxide
exposure include the combustion of
fossil fuels, smelting of sulfide ores,
volcanic emissions, and other natural
sources. Sulfur dioxide is also used to
manufacture hydrosulfites, to bleach
wood pulp and paper, to process,
disinfect, and bleach food, for waste and
water treatment, and in metal, ore, and
oil refining (ATSDR 2004). Sufficient
information is available from public
sources to adequately characterize
sulfur dioxide.
C. Safety Factor for Infants and Children
There is sufficient toxicological
information for sulfur dioxide to
address risks to infants and children.
The available information indicates that
there is no evidence of increased
quantitative or qualitative susceptibility
of the offspring after in utero or postnatal exposure. Based on the lack of
significant toxicity in existing
toxicological testing of sulfur dioxide
and FDA’s classification of sulfites as
GRAS, EPA has not performed a
quantative risk assessment for sulfur
dioxide using safety factors. For the
same reason, and given the absence of
E:\FR\FM\14SER1.SGM
14SER1
Federal Register / Vol. 76, No. 178 / Wednesday, September 14, 2011 / Rules and Regulations
any evidence of pre- or post-natal
sensitivity to sulfur dioxide, EPA
concludes that there is reliable data to
support not using an additional safety
factor to protect infants and children.
V. Cumulative Effects From Substances
With a Common Mechanism of Toxicity
Section 408(b)(2)(D)(v) of FFDCA
requires that, when considering whether
to establish, modify, or revoke a
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 has not found inorganic sulfites
to share a common mechanism of
toxicity with any other substances, and
sulfur dioxide does not appear to
produce a toxic metabolite produced by
other substances. For the purposes of
this tolerance action, therefore, EPA has
assumed that sulfur dioxide does not
have 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 EPA’s Web site at
https://www.epa.gov/pesticides/
cumulative.
VI. Determination of Safety for U.S.
Population, Infants and Children
The residue levels expected from this
use on figs are relatively low when
compared to concentrations of sulfites
in many common foods and viewed as
GRAS by the FDA. Given the low fig use
rate, low expected residue levels, and
relatively low consumption of figs, the
safety finding made in the May 2007
RED assessment for the post-harvest use
on grapes may be extended to include
the proposed tolerance level of 10 ppm
on figs. EPA concludes that there is a
reasonable certainty that no harm will
result to the general population, or to
sulfite sensitive individuals, infants and
children, from aggregate exposure to
residues of sulfur dioxide, including its
metabolites and degradates.
VII. Other Considerations
tkelley on DSKG8SOYB1PROD with RULES
A. Analytical Enforcement Methodology
For the determination of residues in
food, the FDA has published a
titrimetric method of analysis capable of
providing a 10 ppm LOD. It is
delineated in 21 CFR part 101 Appendix
A and is based on the Association of
Official Agricultural Chemists official
method for sulfites. For this procedure,
sulfur dioxide is steam distilled from
the crop sample and trapped in
VerDate Mar<15>2010
13:34 Sep 13, 2011
Jkt 223001
hydrogen peroxide to produce sulfuric
acid. The sulfuric acid is then titrated
against aqueous sodium hydroxide and
expressed as sulfur dioxide. The sulfur
dioxide concentrations are converted to
sulfite residues with molecular weight
conversions. Adequate recovery data are
available to support the use of this
procedure as a tolerance enforcement
method.
B. International Residue Limits
In making its tolerance decisions, EPA
seeks to harmonize U.S. tolerances with
international standards whenever
possible, consistent with U.S. food
safety standards and agricultural
practices. EPA considers the
international maximum residue limits
(MRLs) established by the Codex
Alimentarius Commission (Codex), as
required by FFDCA section 408(b)(4).
The Codex Alimentarius is a joint U.N.
Food and Agriculture Organization/
World Health Organization food
standards program, and it is recognized
as an international food safety
standards-setting organization in trade
agreements to which the United States
is a party. EPA may establish a tolerance
that is different from a Codex MRL;
however, FFDCA section 408(b)(4)
requires that EPA explain the reasons
for departing from the Codex level.
The Codex has not established a MRL
for sulfur dioxide in/on figs.
VIII. Conclusion
Therefore, a time-limited tolerance is
established for residues of sulfur
dioxide, including its metabolites and
degradates, (determined by measuring
only sulfur dioxide (SO2)), at 10 ppm.
This tolerance is effective until
December 31, 2014.
IX. Statutory and Executive Order
Reviews
This final rule establishes tolerances
under sections 408(e) and 408(l)(6) of
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 final rule
has been exempted from review under
Executive Order 12866, this final rule is
not subject to Executive Order 13211,
titled Actions Concerning Regulations
That Significantly Affect Energy Supply,
Distribution, or Use (66 FR 28355, May
22, 2001) or Executive Order 13045,
entitled Protection of Children from
Environmental Health Risks and Safety
Risks (62 FR 19885, April 23, 1997).
This final rule does not contain any
information collections subject to OMB
approval under the Paperwork
PO 00000
Frm 00013
Fmt 4700
Sfmt 4700
56647
Reduction Act (PRA), 44 U.S.C. 3501 et
seq., nor does it require any special
considerations under Executive Order
12898, entitled Federal Actions to
Address Environmental Justice in
Minority Populations and Low-Income
Populations (59 FR 7629, February 16,
1994).
Since tolerances and exemptions that
are established in accordance with
sections 408(e) and 408(l)(6) of FFDCA,
such as the tolerances in this final rule,
do not require the issuance of a
proposed rule, the requirements of the
Regulatory Flexibility Act (RFA) (5
U.S.C. 601 et seq.) do not apply.
This final rule directly regulates
growers, food processors, food handlers,
and food retailers, not States or Tribes,
nor does this action alter the
relationships or distribution of power
and responsibilities established by
Congress in the preemption provisions
of section 408(n)(4) of FFDCA. As such,
the Agency has determined that this
action will not have a substantial direct
effect on States or Tribal governments,
on the relationship between the national
government and the States or Tribal
governments, or on the distribution of
power and responsibilities among the
various levels of government or between
the Federal Government and Indian
Tribes. Thus, the Agency has
determined that Executive Order 13132,
entitled Federalism (64 FR 43255,
August 10, 1999) and Executive Order
13175, entitled Consultation and

II. Background and Statutory Findings
EPA, on its own initiative, in accordance with sections 408(e) and
408(l)(6) of FFDCA, 21 U.S.C. 346a(e) and 346a(1)(6), is establishing a
time-limited tolerance for residues of sulfur dioxide, including its
metabolites and degradates (determined by measuring only sulfur dioxide
(SO2)), at 10 ppm. This time-limited tolerance is effective
until December 31, 2014.
Section 408(l)(6) of 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
[[Page 56645]]
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 FIFRA section 18
related time-limited tolerances to set binding precedents for the
application of section 408 of FFDCA and the safety standard to other
tolerances and exemptions. Section 408(e) of 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 FFDCA allows EPA to establish 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) of FFDCA defines ``safe'' to mean that ``there is a
reasonable certainty that no harm will result from aggregate exposure
to the pesticide chemical residue, including all anticipated dietary
exposures and all other exposures for which there is reliable
information.'' This includes exposure through drinking water and in
residential settings, but does not include occupational exposure.
Section 408(b)(2)(C) of FFDCA 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 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.'' EPA has established
regulations governing such emergency exemptions in 40 CFR part 166.
III. Emergency Exemption for Sulfur Dioxide on Figs and FFDCA
Tolerances
Excessive rain and humidity at flowering and early fruit
development in the spring are critical factors in development of gray
mold caused by Botrytis cinerea (B. cinerea) and these have been high
in the areas where California figs are grown over the past two years.
California estimated that gray mold could be responsible for a 24%
yield loss; and there are no pre or post-harvest fungicides registered
to control B. cinerea on fresh figs.
The Applicant asserts that an emergency condition exists in
accordance with the criteria for approval of an emergency exemption,
and has utilized a crisis exemption under FIFRA section 18 to allow the
use of sulfur dioxide on figs for control of gray mold caused by B.
cinerea in California. After having reviewed the submission, EPA
concurs that an emergency condition exists.
As part of its evaluation of the emergency exemption application,
EPA assessed the potential risks presented by residues of sulfur
dioxide in or on fig. In doing so, EPA considered the safety standard
in section 408(b)(2) of FFDCA, and EPA decided that the necessary
tolerance under section 408(l)(6) of 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 this tolerance without notice and opportunity
for public comment as provided in section 408(l)(6) of FFDCA. Although
these time-limited tolerances expire on December 31, 2014, under
section 408(l)(5) of FFDCA, residues of the pesticide not in excess of
the amounts specified in the tolerance remaining in or on figs after
that date will not be unlawful, provided the pesticide was applied in a
manner that was lawful under FIFRA, and the residues do not exceed a
level that was authorized by this time-limited tolerance at the time of
that application. EPA will take action to revoke this time-limited
tolerance earlier if any experience with, scientific data on, or other
relevant information on this pesticide indicate that the residues are
not safe.
Because this time-limited tolerance is being approved under
emergency conditions, EPA has not made any decisions about whether
sulfur dioxide meets FIFRA's registration requirements for use on fig
or whether a permanent tolerance for this use would be appropriate.
Under these circumstances, EPA does not believe that this time-limited
tolerance decision serves as a basis for registration of sulfur dioxide
by a State for special local needs under FIFRA section 24(c). Nor does
this tolerance by itself serve as the authority for persons in any
State other than California to use this pesticide on the applicable
crops under FIFRA section 18 absent the issuance of an emergency
exemption applicable within that State. For additional information
regarding the emergency exemption for sulfur dioxide, contact the
Agency's Registration Division at the address provided under FOR
FURTHER INFORMATION CONTACT.
IV. Aggregate Risk Assessment and Determination of Safety
Section 408(b)(2)(A)(i) of FFDCA allows EPA to establish 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) of FFDCA defines ``safe'' to mean that ``there is a
reasonable certainty that no harm will result from aggregate exposure
to the pesticide 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) of
FFDCA 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. * * *''
Consistent with the factors specified in FFDCA section
408(b)(2)(D), 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 sulfite sensitive
individuals, infants and children. EPA has sufficient data to assess
the hazards of and to make a determination on aggregate exposure
expected as a result of this emergency exemption request and the time-
limited tolerances for residues of sulfur dioxide, including its
metabolites and degradates (determined by measuring only sulfur dioxide
(SO2)), at 10 ppm. EPA's assessment of exposures and risks
associated with establishing time-limited tolerances 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, and infants
and children, as well as sulfite sensitive individuals.
Evaluations performed by the World Health Organization (WHO), the
[[Page 56646]]
International Agency for Research on Cancer (IARC), and the Agency for
Toxic Substances and Disease Registry (ATSDR) were relied upon for the
safety finding for sulfur dioxide made in the May 2007 RED assessment
on inorganic sulfites, which includes the chemicals sulfur dioxide and
sodium metabisulfite (end-use inorganic sulfite products contain sulfur
dioxide at 99.9 to 100%, and sodium metabisulfite at 37.5 to 98.5%.
These assessments are based on peer-reviewed evaluations performed by
the Cosmetic Ingredient Review (a program established in 1976 by the
Cosmetic, Toiletry & Fragrance Association, now known as the Personal
Care Products Council (PCPC), with the support of the U.S. Food and
Drug Administration (FDA) and the Consumer Federation of America (CFA);
the Organization for Economic Cooperation and Development-Screening
Information Data Set and from other open literature sources. People may
be exposed to small amounts of sulfur through the food supply. However,
since sulfur does not cause any relevant toxic effects, no quantitative
dietary risk assessment is needed. Short-term studies show that sulfur
is of very low acute oral toxicity and does not irritate the skin (it
has been placed in Toxicity Category IV, the least toxic category, for
these effects). Sulfur dioxide (21 CFR 182.3862) is listed as Generally
Recognized as Safe (GRAS) by the FDA as a preservative in certain
foods. The Select Committee on GRAS Substances (a committee of
qualified scientists contracted by FDA to review and evaluate the
safety of GRAS substances) concluded that: ``There is no evidence in
the available information on sulfur dioxide that demonstrates, or
suggests reasonable grounds to suspect, a hazard to the public when
used at levels that are now current and in the manner now practiced.''
This conclusion was based on the knowledge that orally administered
sulfite is very rapidly oxidized to sulfate in all species studied. The
metabolic removal of sulfite appears to be the critical defense
mechanism. The WHO has emphasized the use of appropriate labeling for
alerting individuals who cannot tolerate sulfites. After receiving and
reviewing reports of adverse reactions in certain individuals following
ingestion of sulfiting agents used as preservatives in food products,
beverages, and fresh fruits and vegetables, the FDA requires ingredient
labels to list sulfite concentrations in excess of 10 ppm. Several
regulatory endpoints and standards for ambient air concentrations of
sulfur dioxide have been established at the state, Federal and
international levels. The endpoint selected by the Agency for the
bystander inhalation risk assessment is 0.25 ppm sulfur dioxide, with
one-hour exposure duration. The 0.25 ppm concentration is based on an
ambient air quality standard set by the California Air Resources Board.
This endpoint is deemed most applicable to this exposure scenario, as
it is based on effects of concern for bystanders (such as
bronchoconstriction, shortness of breath, wheezing, and chest tightness
during physical activity in persons with asthma).
B. Exposure Assessment
1. Dietary exposure from food and feed uses. In evaluating dietary
exposure to sulfur dioxide, EPA considered exposure under the time-
limited tolerances established by this action, as well as all existing
sulfur dioxide tolerances in 40 CFR 180.444. Exposures to sulfites when
used as an active or inert pesticide ingredient are minimal because it
is known to be readily biodegradable, quickly oxidized, and rapidly
excreted from the body. In addition, sulfur dioxide (21 CFR 182.3862)
is listed as GRAS by the FDA, with limitations, as a food preservative.
As such, sulfites are found in many foods, primarily as a result of the
GRAS preservative use. It is estimated that sulfite concentrations of
>100 ppm may be found in dried fruits (excluding dark raisins and
prunes), lemon and lime juices, wine, molasses, and sauerkraut juice.
Dried potatoes, grape juice, wine vinegar, gravies, fruit topping, and
maraschino cherries may contain between 50 and 100 ppm sulfur dioxide.
Foods containing between 10 ppm and 50 ppm include pectin, fresh
shrimp, corn syrup, sauerkraut, pickled foods, corn starch, hominy,
frozen potatoes, maple syrup, imported jams and jellies, and fresh
mushrooms (CIR 2003). Preliminary data developed by the Interregional
Research Project No. 4 (IR-4) from the concluded experimental phase of
a study now being conducted on figs was submitted with this exemption
request. The design of the IR-4 study is sufficient in its scope having
followed the protocol put forward for determining the magnitude of the
residue on fresh figs from the use of sulfur dioxide. This study shows
that following application made at a 10x exaggerated rate of 250 ppm
sulfur dioxide/hour, samples analyzed from 1 hour up to 28 days after
treatment were all found to have residue levels of sulfur dioxide below
the limit of detection (LOD) of 10 ppm. In view of the data provided by
IR-4, a linear extrapolation from the 10x exaggerated rate to a 1x
application rate determined that a 1x rate is likely to result in
residue levels of sulfur dioxide of 2.5 ppm or lower when following the
use-pattern in this crisis exemption.
2. Drinking water exposure. Based on environmental fate information
for sulfur dioxide and the requested post-harvest use pattern (in
closed chambers), concentrations of concern are not expected in
drinking water.
3. Inhalation exposure. Based on the Probabilistic Exposure and
Risk Model for Fumigants, version 2.1.1 (PERFUM2) the requested use is
expected to limit bystander exposure potential to sulfur dioxide
concentrations at or below 0.25 ppm. This bystander exposure scenario
is considered ``worst-case,'' in that it assumes the ventilation stack
is at the edge of the treatment warehouse, and the warehouse is in
close proximity to the fumigation facility property line.
4. Other non-occupational exposure. In examining aggregate
exposure, section 408 of FFDCA directs EPA to consider available
information concerning exposures from the pesticide residue in food and
all other non-occupational exposures, including drinking water from
ground water or surface water and exposure through pesticide use in
gardens, lawns, or buildings (residential and other indoor uses).
Currently there are no residential uses for sulfur dioxide, as the use
of inorganic sulfites is limited to postharvest fumigation of grapes.
Environmental sources of sulfur dioxide exposure include the combustion
of fossil fuels, smelting of sulfide ores, volcanic emissions, and
other natural sources. Sulfur dioxide is also used to manufacture
hydrosulfites, to bleach wood pulp and paper, to process, disinfect,
and bleach food, for waste and water treatment, and in metal, ore, and
oil refining (ATSDR 2004). Sufficient information is available from
public sources to adequately characterize sulfur dioxide.
C. Safety Factor for Infants and Children
There is sufficient toxicological information for sulfur dioxide to
address risks to infants and children. The available information
indicates that there is no evidence of increased quantitative or
qualitative susceptibility of the offspring after in utero or post-
natal exposure. Based on the lack of significant toxicity in existing
toxicological testing of sulfur dioxide and FDA's classification of
sulfites as GRAS, EPA has not performed a quantative risk assessment
for sulfur dioxide using safety factors. For the same reason, and given
the absence of
[[Page 56647]]
any evidence of pre- or post-natal sensitivity to sulfur dioxide, EPA
concludes that there is reliable data to support not using an
additional safety factor to protect infants and children.
V. Cumulative Effects From Substances With a Common Mechanism of
Toxicity
Section 408(b)(2)(D)(v) of FFDCA requires that, when considering
whether to establish, modify, or revoke a 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 has not found inorganic sulfites to share a common mechanism of
toxicity with any other substances, and sulfur dioxide does not appear
to produce a toxic metabolite produced by other substances. For the
purposes of this tolerance action, therefore, EPA has assumed that
sulfur dioxide does not have 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 EPA's Web site at https://www.epa.gov/pesticides/cumulative.
VI. Determination of Safety for U.S. Population, Infants and Children
The residue levels expected from this use on figs are relatively
low when compared to concentrations of sulfites in many common foods
and viewed as GRAS by the FDA. Given the low fig use rate, low expected
residue levels, and relatively low consumption of figs, the safety
finding made in the May 2007 RED assessment for the post-harvest use on
grapes may be extended to include the proposed tolerance level of 10
ppm on figs. EPA concludes that there is a reasonable certainty that no
harm will result to the general population, or to sulfite sensitive
individuals, infants and children, from aggregate exposure to residues
of sulfur dioxide, including its metabolites and degradates.
VII. Other Considerations
A. Analytical Enforcement Methodology
For the determination of residues in food, the FDA has published a
titrimetric method of analysis capable of providing a 10 ppm LOD. It is
delineated in 21 CFR part 101 Appendix A and is based on the
Association of Official Agricultural Chemists official method for
sulfites. For this procedure, sulfur dioxide is steam distilled from
the crop sample and trapped in hydrogen peroxide to produce sulfuric
acid. The sulfuric acid is then titrated against aqueous sodium
hydroxide and expressed as sulfur dioxide. The sulfur dioxide
concentrations are converted to sulfite residues with molecular weight
conversions. Adequate recovery data are available to support the use of
this procedure as a tolerance enforcement method.
B. International Residue Limits
In making its tolerance decisions, EPA seeks to harmonize U.S.
tolerances with international standards whenever possible, consistent
with U.S. food safety standards and agricultural practices. EPA
considers the international maximum residue limits (MRLs) established
by the Codex Alimentarius Commission (Codex), as required by FFDCA
section 408(b)(4). The Codex Alimentarius is a joint U.N. Food and
Agriculture Organization/World Health Organization food standards
program, and it is recognized as an international food safety
standards-setting organization in trade agreements to which the United
States is a party. EPA may establish a tolerance that is different from
a Codex MRL; however, FFDCA section 408(b)(4) requires that EPA explain
the reasons for departing from the Codex level.
The Codex has not established a MRL for sulfur dioxide in/on figs.
VIII. Conclusion
Therefore, a time-limited tolerance is established for residues of
sulfur dioxide, including its metabolites and degradates, (determined
by measuring only sulfur dioxide (SO2)), at 10 ppm. This
tolerance is effective until December 31, 2014.
IX. Statutory and Executive Order Reviews
This final rule establishes tolerances under sections 408(e) and
408(l)(6) of 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 final rule has been exempted from review under
Executive Order 12866, this final rule is not subject to Executive
Order 13211, titled Actions Concerning Regulations That Significantly
Affect Energy Supply, Distribution, or Use (66 FR 28355, May 22, 2001)
or Executive Order 13045, entitled Protection of Children from
Environmental Health Risks and Safety Risks (62 FR 19885, April 23,
1997). This final rule does not contain any information collections
subject to OMB approval under the Paperwork Reduction Act (PRA), 44
U.S.C. 3501 et seq., nor does it require any special considerations
under Executive Order 12898, entitled Federal Actions to Address
Environmental Justice in Minority Populations and Low-Income
Populations (59 FR 7629, February 16, 1994).
Since tolerances and exemptions that are established in accordance
with sections 408(e) and 408(l)(6) of FFDCA, such as the tolerances in
this final rule, do not require the issuance of a proposed rule, the
requirements of the Regulatory Flexibility Act (RFA) (5 U.S.C. 601 et
seq.) do not apply.
This final rule directly regulates growers, food processors, food
handlers, and food retailers, not States or Tribes, nor does this
action alter the relationships or distribution of power and
responsibilities established by Congress in the preemption provisions
of section 408(n)(4) of FFDCA. As such, the Agency has determined that
this action will not have a substantial direct effect on States or
Tribal governments, on the relationship between the national government
and the States or Tribal governments, or on the distribution of power
and responsibilities among the various levels of government or between
the Federal Government and Indian Tribes. Thus, the Agency has
determined that Executive Order 13132, entitled Federalism (64 FR
43255, August 10, 1999) and Executive Order 13175, entitled
Consultation and Coordination with Indian Tribal Governments (65 FR
67249, November 9, 2000) do not apply to this final rule. In addition,
this final rule does not impose any enforceable duty or contain any
unfunded mandate as described under Title II of the Unfunded Mandates
Reform Act of 1995 (UMRA) (Pub. L. 104-4).
This action does not involve any technical standards that would
require Agency consideration of voluntary consensus standards pursuant
to section 12(d) of the National Technology Transfer and Advancement
Act of 1995 (NTTAA), Public Law 104-113, section 12(d) (15 U.S.C. 272
note).
X. Congressional Review Act
The Congressional Review Act, 5 U.S.C. 801 et seq., generally
provides that before a rule may take effect, the agency promulgating
the rule must submit a rule report to each House of the Congress and to
the Comptroller General of the United States. EPA will submit a report
containing this rule and other required information to the U.S. Senate,
the U.S. House of Representatives, and the Comptroller General of the
United States prior to
[[Page 56648]]
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).
