 Environmental Protection Agency 40 CFR Part 180
[EPA-HQ-OPP-2011-0117; FRL-8863-2]
 AGENCY: Environmental Protection Agency (EPA).
 ACTION: Final rule.
 SUMMARY: This regulation establishes an exemption from the requirement of a tolerance for residues of potassium benzoate (Cas No. 582-25-2) under 40 CFR 180.910 when used as an inert ingredient (preservative) in pesticide formulations applied to growing crops and raw agricultural commodities after harvest, and under 40 CFR 180.930 when used as an inert ingredient (preservative) in pesticide formulations applied to animals (used for food). Landis International, on behalf of Whitmire Micro-Gen submitted two petitions to EPA under the Federal Food, Drug, and Cosmetic Act (FFDCA), requesting establishment of an exemption from the requirement of a tolerance. This regulation eliminates the need to establish a maximum permissible level for residues of potassium benzoate.
 DATES: This regulation is effective March 9, 2011. Objections and requests for hearings must be received on or before May 9, 2011, and must be filed in accordance with the instructions provided in 40 CFR part 178 (

                    **Federal Register**
                     of February 6, 2008 (73 FR 6964) (FRL-8350-9), EPA issued a notice pursuant to section 408 of FFDCA, 21 U.S.C. 346a, announcing the filing of a pesticide petition (PP 7E7241) by Landis International, on behalf of Whitmire Micro-Gen, 3185 Madison Highway, P.O. Box 5126, Valdosta, GA 31603-5126, under docket ID number EPA-HQ-OPP-2008-0040. The petition requested that 40 CFR 180.910 be amended by establishing an exemption from the requirement of a tolerance for residues of potassium benzoate (Cas No. 582-25-2) when used as an inert ingredient (preservative) in pesticide formulations applied pre- and post-harvest. In the 
                    **Federal Register**
                     of June 4, 2008 (73 FR 31862) (FRL-8365-3), EPA issued a notice pursuant to section 408 of FFDCA, 21 U.S.C. 346a, announcing the filing of a pesticide petition (PP 8E7333) by Landis International, on behalf of Whitmire Micro-Gen, 3185 Madison Highway, P.O. Box 5126, Valdosta, GA 31603-5126, under docket ID number EPA-HQ-OPP-2008-0059. The petition requested that 40 CFR 180.930 be amended by establishing an exemption from the requirement of a tolerance for residues of potassium benzoate (Cas No. 582-25-2) when used as an inert ingredient (preservative) in pesticide formulations applied to animals. Both notices referenced a summary of the petition prepared by Landis International, on behalf of Whitmire Micro-Gen, the petitioner, which is available in the docket, 
                    *http://www.regulations.gov.*
                     Two comments were received in the docket for PP 7E7241, however they are unrelated to potassium benzoate and the Agency believes they were placed in this docket in error by the commenters. There were no comments received in response to the notice of filing for PP 8E7333. III. Inert Ingredient Definition Inert ingredients are all ingredients that are not active ingredients as defined in 40 CFR 153.125 and include, but are not limited to, the following types of ingredients (except when they have a pesticidal efficacy of their own): Solvents such as alcohols and hydrocarbons; surfactants such as polyoxyethylene polymers and fatty acids; carriers such as clay and diatomaceous earth; thickeners such as carrageenan and modified cellulose; wetting, spreading, and dispersing agents; propellants in aerosol dispensers; microencapsulating agents; and emulsifiers. The term “inert” is not intended to imply nontoxicity; the ingredient may or may not be chemically active. Generally, EPA has exempted inert ingredients from the requirement of a tolerance based on the low toxicity of the individual inert ingredients. IV. Aggregate Risk Assessment and Determination of Safety Section 408(c)(2)(A)(i) of FFDCA allows EPA to establish an exemption from the requirement for a tolerance (the legal limit for a pesticide chemical residue in or on a food) only if EPA determines that the tolerance is “safe.” Section 408(b)(2)(A)(ii) 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 res idue * * *.” EPA establishes exemptions from the requirement of a tolerance only in those cases where it can be clearly demonstrated that the risks from aggregate exposure to pesticide chemical residues under reasonably foreseeable circumstances will pose no appreciable risks to human health. In order to determine the risks from aggregate exposure to pesticide inert ingredients, the Agency considers the toxicity of the inert in conjunction with possible exposure to residues of the inert ingredient through food, drinking water, and through other exposures that occur as a result of pesticide use in residential settings. If EPA is able to determine that a finite tolerance is not necessary to ensure that there is a reasonable certainty that no harm will result from aggregate exposure to the inert ingredient, an exemption from the requirement of a tolerance may be established. Consistent with section 408(c)(2)(A) of FFDCA, and the factors specified in FFDCA section 408(c)(2)(B), 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 aggregate exposure for potassium benzoate including exposure resulting from the exemption established by this action. EPA's assessment of exposures and risks associated with potassium benzoate follows. A. Toxicological Profile EPA has evaluated the available toxicity data and considered their validity, completeness, and reliability as well as the relationship of the results of the studies to human risk. EPA has also considered available information concerning the variability of the sensitivities of major identifiable subgroups of consumers, including infants and children. Potassium benzoate is an approved food preservative, similar in structure and reactivity to the more widely used sodium benzoate. Both are classified by the U.S. Food and Drug Administration (FDA) as Generally Recognized as Safe (GRAS). In conducting this assessment, toxicity data on potassium benzoate and the surrogate chemicals sodium benzoate and benzoic acid were used. Both potassium benzoate and sodium benzoate are salts of benzoic acid. Because all benzoates, in particular benzoic acid and sodium benzoate, react similarly to potassium benzoate, they were used as surrogates in the development of this profile. Available data show that the acute toxicity of potassium benzoate is negligible, having an oral median lethal dose (LD50) of >10,000 milligrams per kilogram body weight (mg/kg/bw). Acute dermal and inhalation toxicity is low as indicated by the >2,000 mg/kg/bw LD50
                     and >12.2 milligrams per liter (mg/L) median lethal concentration (LC50) of benzoic acid. Sodium benzoate was not irritating to the skin and induced only slight eye irritation in rabbits. Sodium benzoate and benzoic acid were non-sensitizing in animal tests but showed a very low incidence of sensitization in humans patch tested. Both sodium benzoate and benzoic acid are known to induce non-immunogenic contact reactions, and that is the likely explanation for the low positive response. Subacute, subchronic and chronic toxicity data also indicate that potassium benzoate should be relatively nontoxic. Available oral and dermal studies had a no-observed-adverse-effect-level (NOAEL) ≥2,000 mg/kg/bw and the inhalation study had a NOAEL >25 milligrams per cubic meter (mg/m3
                    ). Sodium benzoate was not 
                    ( print page 12875)
                    carcinogenic in a lifetime mouse feeding study and there is no indication that potassium benzoate should be neurotoxic. Genotoxicity studies indicate the benzoates are not mutagenic; however chromosomal aberration studies gave ambiguous results. Benzoic acid did not induce reproductive toxicity in a 4-generation study. In the human body under normal physiological conditions, potassium benzoate changes from the ionized form to the undissociated benzoic acid. Benzoic acid and its salts are rapidly absorbed by mammals, conjugated with glycine, and rapidly excreted in the urine as hippuric acid. There is no reported accumulation of benzoate in the body. However, the ability to conjugate benzoic acid depends upon adequate liver function and nutritional supply of glycine. All data indicates that potassium benzoate is relatively non-toxic as are the other benzoates. No toxicity would be expected from potassium benzoate when used at low concentrations in pesticides. No developmental toxicity studies are available in the database. However, no systemic toxicity was observed at doses up to 750 mg/kg/day, the highest dose tested (HDT), in a 4-generation reproductive study with benzoic acid. In addition, no systemic toxicity was observed in the laboratory animals at high doses >2,000 mg/kg/day of potassium benzoate and benzoates indicating relatively low hazard potential. Specific information on the studies received and the nature of the adverse effects caused by potassium benzoate as well as the NOAEL and the lowest-observed-adverse-effect-level (LOAEL) from the toxicity studies can be found at 
                    *http://www.regulations.gov*
                     in the document “PC Code 709103: Potassium Benzoate (CAS Reg. No. 582-25-2); Human Health Risk Assessment and Ecological Effects Assessment to the Support Proposed Exemption from the Requirement of a Tolerance When Used as an Inert Ingredient in Pesticide Formulations,” page 7 docket ID number EPA-HQ-OPP-2011-0117. B. Toxicological Points of Departure/Levels of Concern Subacute, subchronic and chronic toxicity data indicate that potassium benzoate is relatively nontoxic. Available oral and dermal toxicity studies had a NOAEL greater than or equal to 2,000 mg/kg/day and the inhalation study had a NOAEL greater than 25 mg/m3
                    . Sodium benzoate was not shown to be carcinogenic and there is no indication that potassium benzoate will be neurotoxic. Studies also indicate that benzoates are not mutagenic and benzoic acid did not induce reproductive toxicity in a 4-generation study. Since no toxicity was observed at high doses, quantitative risk assessment is deemed unnecessary. C. Exposure Assessment No hazard was identified for the acute and chronic dietary assessment (food and drinking water), or for the short, intermediate, and long term residential assessments, therefore no aggregate risk assessments were performed. Available toxicological studies indicate lack of systemic toxicity at doses up to 2,000 mg/kg/day. Therefore, no quantitative dietary or occupational and residential risk assessment was conducted. 1. 
                    *Dietary exposure from food and feed uses**and drinking water.*
                     In evaluating dietary exposure to potassium benzoate, EPA considered exposure under the proposed exemption from the requirement of a tolerance. Since toxicity was seen only at doses greater than 2,000 mg/kg/day for potassium benzoate, a quantitative exposure assessment for potassium benzoate was not conducted. Any possible dietary exposure to potassium benzoate from its use as an inert ingredient in pesticide products would be through consumption of food to which pesticide products containing it have been applied and possibly through drinking water (from runoff). Metabolism data indicates that potassium benzoate would be rapidly absorbed, metabolized, and excreted. 2. 
                    *From non-dietary exposure.*
                     The term “residential exposure” is used in this document to refer to non-occupational, non-dietary exposure (
                    *e.g.,*
                     textiles (clothing and diapers), carpets, swimming pools, and hard surface disinfection on walls, floors, tables). Potassium benzoate is used in pharmaceuticals and cosmetics. It can also be used in nonfood use pesticide products. Considering the low toxicity of potassium benzoate, residues of concern are not anticipated from residential exposures (inhalation and dermal) and therefore a quantitative aggregate risk assessment was not performed. 3. 
                    *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 potassium benzoate to share a common mechanism of toxicity with any other substances, and potassium benzoate does not appear to produce a toxic metabolite produced by other substances. For the purposes of this tolerance action, therefore, EPA has assumed that potassium benzoate 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 
                    *http://www.epa.gov/​pesticides/​cumulative.* D. Safety Factor for Infants and Children 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 FQPA Safety Factor (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. No developmental toxicity studies are available in the database. However, no systemic toxicity was observed at doses up to 750 mg/kg/day in a 4-generation reproductive study with benzoic acid. In addition, no systemic toxicity was observed in the laboratory animals at high doses >2,000 mg/kg/day of potassium benzoate and benzoates indicating relatively low hazard potential. There was no evidence of clinical signs of neurotoxicity, therefore, a developmental neurotoxicity study is not required. In addition, no evidence of immunotoxicity is available in the database, therefore, an immunotoxicity study is not required. In terms of hazard, there are low concerns and low residual uncertainties regarding prenatal and/or postnatal toxicity. Based on this information, there is no concern at this time for increased sensitivity to infants and children to potassium benzoate when used as an inert ingredient in pesticide formulations and a safety factor analysis has not been used to assess risk. For the same reason, EPA has determined that an additional safety factor is not needed to protect the safety of infants and children.
                    ( print page 12876) E. Aggregate Risks and Determination of Safety Given the lack of concern for hazard posed by potassium benzoate, EPA concludes that there are no dietary or aggregate dietary/non-dietary risks of concern as a result of exposure to potassium benzoate in food and water or from residential exposure. Residues of concern are not anticipated for dietary exposure (food and drinking water) or for residential exposure (dermal and inhalation) from the use of potassium benzoate as an inert ingredient in pesticide products. As discussed in this unit, EPA expects aggregate exposure to potassium benzoate to pose no appreciable dietary risk given that the data show a lack of any systemic toxicity at doses up to 2,000 mg/kg/day and a lack of any apparent developmental effects. Taking into consideration all available information on potassium benzoate, EPA has determined that there is a reasonable certainty that no harm to any population subgroup, including infants and children, will result from aggregate exposure to potassium benzoate under reasonably foreseeable circumstances. Therefore, the establishment of an exemption from tolerance under 40 CFR 180.910 for residues of potassium benzoate when used as an inert ingredient in pesticide formulations applied pre- and post-harvest and under 40 CFR 180.930 for residues of potassium benzoate when used as an inert ingredient in pesticide formulations applied to animals, is safe under FFDCA section 408. V. Other Considerations A. Analytical Enforcement Methodology An analytical method is not required for enforcement purposes since the Agency is establishing an exemption from the requirement of a tolerance without any numerical limitation. 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 potassium benzoate. VI. Conclusions Therefore, an exemption from the requirement of a tolerance is established under 40 CFR 180.910 and 40 CFR 180.930 for potassium benzoate when used as an inert ingredient (preservative) in pesticide formulations applied pre- and post-harvest and applied to animals. VII. Statutory and Executive Order Reviews This final rule establishes a tolerance under section 408(d) of FFDCA in response to a petition submitted to the Agency. The Office of Management and Budget (OMB) has exempted these types of actions from review under Executive Order 12866, entitled 
                    *Regulatory Planning and Review*
                     (58 FR 51735, October 4, 1993). Because this final rule has been exempted from review under Executive Order 12866, this final rule 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). 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 on the basis of a petition under section 408(d) of FFDCA, 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 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). VIII. 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 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). List of Subjects in 40 CFR Part 180 Environmental protection
