II. Summary of Petitioned-For Tolerance
In the Federal Register of June 28, 2021 (86 FR 33922) (FRL-10025-
08), EPA issued a document pursuant to FFDCA section 408(d)(3), 21
U.S.C. 346a(d)(3), announcing the filing of a pesticide petition (PP
0E8894) by IR-4, North Carolina State University, 1730 Varsity Drive,
Venture IV, Suite 210, Raleigh, NC 27606. The petition requested to
amend 40 CFR part 180 by establishing tolerances for residues of sulfur
dioxide, including its metabolite and degradates, in or on blueberry at
9 parts per million (ppm). That document referenced a summary of the
petition prepared by IR-4, the petitioner, which is available in the
docket, <a href="https://www.regulations.gov">https://www.regulations.gov</a>. Two comments were received on the
notice of filing from the United States Department of Agriculture and
the North American Blueberry Council. Both were in support of the
action.
III. 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 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.. .
.''
Consistent with FFDCA section 408(b)(2)(D), and 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. EPA has sufficient data to assess the hazards of and to make a
determination on
[[Page 68910]]
aggregate exposure for sulfur dioxide including exposure resulting from
the tolerances established by this action. EPA's assessment of
exposures and risks associated with these inorganic sulfites follow.
A. Toxicological Profile
There is a large volume of published data detailing the toxicity of
sulfur dioxide and sodium metabisulfite, and consequently the toxicity
of these pesticides has been well established. Sodium metabisulfite
pads generate sulfur dioxide gas which then reacts with foods to
quickly form sulfite. In addition to the use of sodium metabisulfite
pads, direct application of sulfur dioxide gas is proposed for
blueberry treatments. For both treatments, sulfite is the residue of
concern in food and is determined by the analytical enforcement method.
EPA's Office of Air Quality Planning and Standards (OAQPS) has worked
extensively on sulfur dioxide, including setting national ambient air
quality standards (NAAQS) for sulfur dioxide, a gaseous air pollutant.
The U.S. Food and Drug Administration (FDA) has also performed an
extensive review of sulfiting agents (including sulfur dioxide, sodium
metabisulfite, and sodium bisulfite) that have been added to any food
or to any ingredient in any food. For the dietary assessment, EPA is
relying on the established FDA regulatory value for sulfite.
Sulfiting agents are used to add sulfites to foods and include
sulfur dioxide, sodium metabisulfite, sodium bisulfite, sodium sulfite,
potassium metabisulfite, and potassium bisulfite. Humans may experience
sensitivity reactions following exposure to sulfites including, but not
limited to, diarrhea, headache, difficulty breathing, vomiting and
nausea, and abdominal pain and cramps. Asthmatics account for many, but
not necessarily all, of the individuals who have a sensitivity to
sulfites. Given the known effects to certain individuals within the
population, the FDA requires that any food that contains a sulfiting
agent at >= 10 ppm or mg/kg be declared as such on the food label.
Additional information on the toxicological profile can be found at
<a href="https://www.regulations.gov">https://www.regulations.gov</a> in the document titled ``Inorganic
Sulfites. Human Health Risk Assessment in Support of a Section 3
Registration for Postharvest Fumigation of Blueberry'' (hereinafter
``Sulfur Dioxide Human Health Risk Assessment'') in docket ID number
EPA-HQ-OPP-2021-0203.
B. Toxicological Points of Departure/Levels of Concern
No appropriate toxicological endpoints were selected for sulfur
dioxide. The Agency is relying on the FDA-established regulatory level
of up to 10 ppm sulfite residues in foods.
C. Exposure Assessment
1. Dietary exposure from food and feed uses. In evaluating dietary
exposure to sulfur dioxide, EPA compared exposure from residues on
blueberries to the FDA-established regulatory level. EPA assessed
dietary exposures from these inorganic sulfites in food as follows:
Sulfite is the residue of concern for consumption of treated
blueberries. A quantitative dietary assessment was not conducted for
sulfite since no appropriate toxicological endpoints were selected. The
Agency is relying on the FDA-established regulatory level of up to 10
ppm sulfite residues in foods. Residues of sulfites in blueberry from
sulfur dioxide and sodium metabisulfite applications are expected to be
below the 10 ppm level when applied as tested in the blueberry residue
trials.
EPA did not use anticipated residue or PCT information in the
dietary assessment for sulfur dioxide.
2. Dietary exposure from drinking water. No residues are expected
in drinking water based on the current use pattern, which includes
post-harvest fumigant treatment in a chamber and slow release or dual
release pads that are placed in the clamshells used to distribute
blueberries.
3. From non-dietary exposure. The term ``residential exposure'' is
used in this document to refer to non-occupational, non-dietary
exposure (e.g., for lawn and garden pest control, indoor pest control,
termiticides, and flea and tick control on pets).
There are no uses of sulfur dioxide or sodium metabisulfite
resulting in direct residential exposures; therefore, residential
exposure is not expected.
4. 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.''
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 the inorganic sulfites and
any other substances and the inorganic sulfites do not appear to
produce a toxic metabolite produced by other substances. For the
purposes of this tolerance action, therefore, EPA has not assumed that
the inorganic sulfites have a common mechanism of toxicity with other
substances.
D. Safety Factor for Infants and Children
1. In general. Section 408(b)(2)(C) of FFDCA provides that EPA
shall apply an additional tenfold (10X) margin of safety for infants
and children in the case of threshold effects to account for prenatal
and postnatal toxicity and the completeness of the database on toxicity
and exposure unless EPA determines based on reliable data that a
different margin of safety will be safe for infants and children. This
additional margin of safety is commonly referred to as the Food Quality
Protection Act Safety Factor (FQPA)(SF). In applying this provision,
EPA either retains the default value of 10X, or uses a different
additional safety factor when reliable data available to EPA support
the choice of a different factor.
Consistent with the factors specified in FFDCA section
408(b)(2)(D), EPA has also reviewed the available scientific data and
other relevant information in support of regulations establishing the
10 ppm maximum permissible level for residues of sulfur dioxide to
support a time-limited tolerance of sulfur dioxide residues in or on
fig (September 14, 2011; 76 FR 56644) (FRL-8887-2). EPA 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 concluded that
there is sufficient toxicological information for sulfur dioxide to
address risks to infants and children. In addition, the available
information indicated 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 observed
susceptibility, and since the current regulatory value for sulfites (10
ppm) takes into account the potential for sensitive populations,
including infants and children, these regulatory values are considered
protective, and no additional FQPA safety factor is required.
E. Aggregate Risks and Determination of Safety
In accordance with the FQPA, the Agency must consider and aggregate
pesticide exposures and risks from three
[[Page 68911]]
major sources: food, drinking water, and residential exposures. There
are no residential uses of sulfur dioxide or sodium metabisulfite, and
exposures through drinking water are not expected based on the use
pattern. Dietary exposures resulting from the proposed uses on
blueberries are expected to be below the 10 ppm FDA-established
regulatory level; therefore, there are no dietary risks of concern from
these uses on blueberries.
Based on these risk assessments, EPA concludes that there is a
reasonable certainty that no harm will result to the general
population, or to infants and children from exposure to inorganic
sulfites resulting from the application of sulfur dioxide and sodium
metabisulfite.
IV. Other Considerations
A. Analytical Enforcement Methodology
An adequate liquid chromatography method with tandem mass
spectrometry detection (LC/MS/MS) method is available for enforcing
sulfite tolerances in blueberries.
The method may be requested from: Chief, Analytical Chemistry
Branch, Environmental Science Center, 701 Mapes Rd., Ft. Meade, MD
20755-5350; telephone number: (410) 305-2905; email address:
<a href="/cdn-cgi/l/email-protection#067463756f6273636b63726e6962754663766728616970"><span class="__cf_email__" data-cfemail="d1a3b4a2b8b5a4b4bcb4a5b9beb5a291b4a1b0ffb6bea7">[email protected]</span></a>.
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).
There are no Codex MRLs for sulfur dioxide in or on blueberry.
V. Conclusion
Therefore, a tolerance is established for residues of sulfur
dioxide in or on blueberry at 9 ppm. EPA is also removing the expired
time-limited tolerance in paragraph (b) and reserving paragraph (b) as
a housekeeping measure.
VI. Statutory and Executive Order Reviews
This action establishes a tolerance under FFDCA section 408(d) 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 action has been
exempted from review under Executive Order 12866, this action is not
subject to Executive Order 13211, entitled ``Actions Concerning
Regulations That Significantly Affect Energy Supply, Distribution, or
Use'' (66 FR 28355, May 22, 2001) or Executive Order 13045, entitled
``Protection of Children from Environmental Health Risks and Safety
Risks'' (62 FR 19885, April 23, 1997), nor is it considered a
regulatory action under Executive Order 13771, entitled ``Reducing
Regulations and Controlling Regulatory Costs'' (82 FR 9339, February 3,
2017). This action does not contain any information collections subject
to OMB approval under the Paperwork Reduction Act (PRA) (44 U.S.C. 3501
et seq.), nor does it require any special considerations under
Executive Order 12898, entitled ``Federal Actions to Address
Environmental Justice in Minority Populations and Low-Income
Populations'' (59 FR 7629, February 16, 1994).
Since tolerances and exemptions that are established on the basis
of a petition under FFDCA section 408(d), such as the tolerance in this
final rule, do not require the issuance of a proposed rule, the
requirements of the Regulatory Flexibility Act (RFA) (5 U.S.C. 601 et
seq.), do not apply.
This action 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 FFDCA section 408(n)(4). 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 action. In addition, this
action does not impose any enforceable duty or contain any unfunded
mandate as described under Title II of the Unfunded Mandates Reform Act
(UMRA) (2 U.S.C. 1501 et seq.).
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 (NTTAA) (15 U.S.C. 272 note).
VII. Congressional Review Act
Pursuant to the Congressional Review Act (5 U.S.C. 801 et seq.),
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. This action is not a ``major rule''
as defined by 5 U.S.C. 804(2).
