40 CFR Part 180
Calcium Gluconate; Exemption From the Requirement of a Tolerance
Environmental Protection Agency (EPA).
This regulation establishes an exemption from the requirement of a tolerance for residues of calcium gluconate when used as an inert ingredient (sequestrant) in pesticide formulations applied to growing crops. ISK Biosciences Corporation submitted a petition 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 calcium gluconate.
This regulation is effective October 31, 2012. Objections and requests for hearings must be received on or before December 31, 2012, and must be filed in accordance with the instructions provided in 40 CFR part 178 (see also Unit I.C. of theSUPPLEMENTARY INFORMATION).

II. Petition for Exemption
In theFederal Registerof May 2, 2012 (77 FR 25957) (FRL-9346-1), EPA issued a notice pursuant to FFDCA section 408, 21 U.S.C. 346a, announcing the filing of a pesticide petition (PP 1E7900) by ISK Biosciences Corporation, 7470 Auburn Road, Suite A, Concord, OH 44077. The petition requested that 40 CFR 180.920 be amended by establishing an exemption from the requirement of a tolerance for residues of calcium gluconate (CAS Reg. No. 299-28-5) when used as an inert ingredient (sequestrant) in pesticide formulations applied to growing crops. That notice referenced a summary of the petition prepared by ISK Biosciences Corporation, the petitioner, which is available in the docket, http://www.regulations.gov. There were no comments received in response to the notice of filing.
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 thepesticide chemical residue * * *.”
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 FFDCA section 408(c)(2)(A), 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 calcium gluconate including exposure resulting from the exemption established by this action. EPA's assessment of exposures and risks associated with calcium gluconate 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. Specific information on the studies received and the nature of the adverse effects caused by calcium gluconate as well as the no-observed-adverse-effect-level (NOAEL) and the lowest-observed-adverse-effect-level (LOAEL) from the toxicity studies are discussed in this unit.
Calcium gluconate has been evaluated by the Joint Food and Agriculture Organization/World Health Organization (FAO/WHO) Expert Committee on Food Additives (JECFA) which determined that calcium gluconate was of very low toxicity and allocated an acceptable daily intake (ADI) of “not specified”. The JECFA evaluation of calcium gluconate was part of a group—gluconic acid and its inorganic salts, that were assessed together based on the fact that the calcium, magnesium, potassium, and sodium salts of gluconic acid are freely ionizable and that it was appropriate to allocate ADIs on the basis of data on their corresponding anion (gluconic acid) as calcium gluconate dissociates under normal physiologic conditions into gluconic acid. ADI “not specified” is used to refer to a food substance of very low toxicity, which, on the basis of available data (chemical, biochemical, toxicological, and other) and the total dietary intake of the substance arising from its use at the levels necessary to achieve the desired effect and from its acceptable background levels in food, does not, in the opinion of the Committee, represent a hazard to health. For that reason, and for reasons stated in individual evaluations, the establishment of an ADI expressed in numerical form is not necessary. Calcium gluconate was added to the CODEX General Standard for Food Additives (GSFA) in 1999.
Toxicological studies considered by JECFA in their evaluation of gluconic acid and its inorganic salts included acute oral toxicity studies in the rat, mouse, rabbit and hamster with LD 50 values ranging from >2,000 milligrams/kilogram (mg/kg) to 7,850 mg/kg. Gluconic acid and its inorganic salts have been tested in in vitro assays (bacterial reverse mutation assays) which demonstrated that gluconic acid was not mutagenic with or without metabolic activation.
In various subchronic, chronic, reproductive and developmental studies evaluated using gluconic acid and its inorganic salts by JECFA, no observable adverse effects were noted at or above limit dose levels (i.e., > 1,000 mg/kg/day). (JECFA 1999).
B. Toxicological Points of Departure/Levels of Concern
As discussed above, there was no hazard identified in repeat dose toxicity and reproductive/developmental studies with gluconic acid and its inorganic salts at the limit dose of 1,000 mg/kg/day to either parental animals or their offspring. Thus, due to its low potential hazard and lack of a hazard endpoint, the Agency has determined that a quantitative risk assessment using safety factors applied to a point of departure protective of an identified hazard endpoint is not appropriate for calcium gluconate.
Calcium gluconate was not mutagenic in an in vitro chromosome aberration test, bacterial gene mutation test. In addition, the available in vitro and in vivo mutagenicity data with glucuronic acid and its inorganic salts were negative. Based on the available information from the mutation studies, it is not anticipated to be carcinogenic.
C. Exposure Assessment
No hazard endpoint of concern for calcium gluconate was identified for the acute and chronic dietary assessment (food and drinking water), or for the short, intermediate, and long term residential assessments (via all exposure routes); therefore, acute and chronic dietary and short-, intermediate-, and long-term residential exposure assessments were not performed.
D. 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.”
While the toxicity of calcium gluconate is expected to be similar to the other inorganic salts of gluconic acid as well as gluconic acid itself, there are no toxicological endpoints of concern identified for any of these substances. Therefore a cumulative risk assessment was not performed.
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.
E. 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 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.
The toxicity database for calcium gluconate identified no hazard endpoint of concern for calcium gluconate and there is no residual uncertainty regarding prenatal and/or postnatal toxicity. No acute or subchronic neurotoxicity studies are available, but there were no clinical signs of neurotoxicity or any systemic toxicity observed in the available database at doses up to 1,000 mg/kg/day. No developmental or reproductive effects were seen in the available studies at doses up to and including 1,000 mg/kg/day.
Based on this information, there is no concern, at this time, for increased sensitivity to infants and children to calcium gluconate when used as an inert ingredient in pesticide formulations applied to growing crops 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.
F. Aggregate Risks and Determination of Safety
Given the lack of concern for hazard posed by calcium gluconate, EPA concludes that there are no dietary or aggregate dietary/non-dietary risks of concern as a result of exposure to calcium gluconate 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 from the use of calcium gluconate as an inert ingredient in pesticide products. As discussed in this unit, EPA expects aggregate exposure to calcium gluconate to pose no appreciable dietary risk given that the data show a lack of any systemic toxicity or adverse developmental/reproductive effects at doses up to 1,000 mg/kg/day.
Taking into consideration all available information on calcium gluconate, 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 calcium gluconate under reasonable foreseeable circumstances. Therefore, the establishment of an exemption from tolerance under 40 CFR 180.920 for residues of calcium gluconate (CAS Reg. No. 299-28-5) when used as an inert ingredient in pesticide formulations applied to growing crops, 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 United Nation 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 calcium gluconate.
Therefore, an exemption from the requirement of a tolerance is established under 40 CFR 180.920 for calcium gluconate (CAS Reg. No. 299-28-5) when used as an inert ingredient (sequestrant) in pesticide formulations applied to growing crops.
VII. Statutory and Executive Order Reviews
This final rule establishes an exemption from the requirement of 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 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 FFDCA section 408(d), such as the tolerance exemption in this final rule, do not require the issuance of a proposed rule, the requirements of the Regulatory Flexibility Act (RFA) (5 U.S.C. 601 et seq.), do not apply.
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 provisionsof 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 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) (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 of 1995 (NTTAA) (15 U.S.C. 272 note).
VIII. 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 theFederal Register. This action is not a “major rule” as defined by 5 U.S.C. 804(2).
