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.

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 E:\FR\FM\14SER1.SGM 14SER1 tkelley on DSKG8SOYB1PROD with RULES 56646 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 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 E:\FR\FM\14SER1.SGM 14SER1 56648 Federal Register / Vol. 76, No. 178 / Wednesday, September 14, 2011 / Rules and Regulations publication of this final rule in the Federal Register. This final rule is not a ‘‘major rule’’ as defined by 5 U.S.C. 804(2).

II. Background and Statutory Findings

    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).
