 Environmental Protection Agency 40 CFR Part 180
[EPA-HQ-OPP-2021-0642; FRL-9536-01-OCSPP]
 AGENCY: Environmental Protection Agency (EPA).
 ACTION: Final rule.
 SUMMARY: This regulation establishes an exemption from the requirement of a tolerance for residues of calcium sulfate when used as an inert ingredient in antimicrobial formulations applied to food-contact surfaces in public eating places, dairy-processing equipment, and food-processing equipment and utensils, limited to 100 parts per million (ppm) in the final formulation. Exponent, Inc. on behalf of Tygrus, LLC, 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 sulfate when used in accordance with this exemption.
 DATES: This regulation is effective March 11, 2022. Objections and requests for hearings must be received on or before May 10, 2022, and must be filed in accordance with the instructions provided in 40 CFR part 178 (see also Unit I.C. of the

                    **Federal Register**
                     of November 23, 2021 (86 FR 66512) (FRL-8792-05), EPA issued a document pursuant to FFDCA section 408, 21 U.S.C. 346a, announcing the filing of a pesticide petition (PP IN-11565) by Exponent, Inc., 1150 Connecticut Ave. NW, Suite 1100, Washington, DC 20036 on behalf of Tygrus, LLC, 1132 E. Big Beaver Road, Troy, MI 48083. The petition requested that 40 CFR 180.940(a) be amended by establishing an exemption from the requirement of a tolerance for residues of calcium sulfate when used as an inert ingredient in antimicrobial formulations applied to food-contact surfaces in public eating places, dairy-processing equipment, and food-processing equipment and utensils, limited to 100 parts per million (ppm) in the final formulation. That document referenced a summary of the petition prepared by Exponent, Inc. on behalf of Tygrus, LLC, the petitioner, which is available in the docket, 
                    *https://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 
                    ( print page 13946)
                    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(c)(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. . . .” 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 harm 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 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 sulfate including exposure resulting from the exemption established by this action. EPA's assessment of exposures and risks associated with calcium sulfate 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 sulfate as well as the no-observed-adverse-effect-level (NOAEL) and the lowest-observed-adverse-effect-level (LOAEL) from the toxicity studies can be found at 
                    *https://www.regulations.gov*
                     in the document “Calcium Sulfate; Human Health Risk Assessment and Ecological Effects Assessment to Support Proposed Exemption from the Requirement of a Tolerance When Used as an Inert Ingredient in Pesticide Formulations” in docket ID number EPA-HQ-OPP-2021-0642. Acute oral toxicity, primary dermal and eye irritation, acute inhalation toxicity and dermal sensitization studies are available for calcium sulfate. The acute oral toxicity of calcium sulfate is low. The acute oral LD50 (lethal dose) in rats is greater than 2,000 milligrams/kilogram (mg/kg). Acute inhalation toxicity is also low; the LC50
                     (lethal concentration) in rats is greater than 2.61 milligrams/liter (mg/L). A study conducted in rabbits indicates it is not irritating to the skin or eye. A study conducted in the guinea pig indicates it is not a dermal sensitizer. Based on the toxicity database for calcium sulfate, no toxicity is observed in a combined repeated dose toxicity study with the reproduction/developmental screening test in rats at the limit dose of 1,000 mg/kg/day. No mutagenicity is seen in the Ames or in the mammalian erythrocyte micronucleus tests. Neurotoxicity and immunotoxicity toxicity studies for calcium sulfate are not available for review. However, no evidence of neurotoxicity or immunotoxicity is seen in the available studies. B. Toxicological Points of Departure/Levels of Concern The available toxicity studies indicate that calcium sulfate has a very low overall toxicity. No toxicity was observed in any of the available studies. Since no endpoint of concern was identified for the acute and chronic dietary exposure assessment and short and intermediate dermal and inhalation exposure, a quantitative risk assessment for calcium sulfate is not necessary. C. Exposure Assessment 1. 
                    *Dietary exposure from food and feed uses.*
                     In evaluating dietary exposure to calcium sulfate, EPA considered exposure under the proposed exemption from the requirement of a tolerance and from existing uses. EPA assessed dietary exposures from calcium sulfate in food as follows: Dietary exposure (food and drinking water) to calcium sulfate may occur following ingestion of foods with residues from use in accordance with this exemption (
                    *e.g.,*
                     ingesting foods that come in contact with surfaces treated with pesticide formulations containing calcium sulfate), as well as non-pesticidal uses in food (see 21 CFR 184.1230). However, a quantitative dietary exposure assessment was not conducted since a toxicological endpoint for risk assessment was not identified. 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). Calcium sulfate may be used in pesticide products and non-pesticide products that may be used in and around the home (
                    *e.g.,*
                     for lawn and garden pest control, indoor pest control) and in personal care products. A quantitative residential exposure assessment was not conducted since a toxicological endpoint for risk assessment was not identified. 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.” Based on the lack of toxicity in the available data, calcium sulfate and its 
                    ( print page 13947)
                    metabolites are not expected to share a common mechanism of toxicity with other chemicals; therefore, section 408(b)(2)(D)(v) does not apply. D. Safety Factor for Infants and Children Section 408(b)(2)(C) of FFDCA provides that EPA shall apply an additional tenfold 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 unless EPA concludes that a different margin of safety will be safe for infants and children. Based on the lack of threshold effects, EPA has not identified any toxicological endpoints of concern and is conducting a qualitative assessment of calcium sulfate. The qualitative assessment does not use safety factors for assessing risk, and no additional safety factor is needed for assessing risk to infants and children. Based on an assessment of calcium sulfate, EPA has concluded that there are no toxicological endpoints of concern for the U.S. population, including infants and children. E. Aggregate Risks and Determination of Safety Taking into consideration all available information on calcium sulfate, EPA has determined that there is a reasonable certainty that no harm will result to the general population, or to infants and children, from aggregate exposure to calcium sulfate residues. Therefore, the establishment of an exemption from the requirement of a tolerance under 40 CFR 180.940(a) for residues of calcium sulfate when used as an inert ingredient in antimicrobial pesticide formulations applied to food-contact surfaces in public eating places, dairy-processing equipment, and food-processing equipment and utensils limited to 100 ppm in the final formulation, is safe under FFDCA section 408. V. Other Considerations Analytical Enforcement Methodology An analytical method is not required for enforcement purposes since the Agency is not establishing a numerical tolerance for residues of calcium sulfate in or on any food commodities. EPA is establishing a limitation on the amount of calcium sulfate that may be used in antimicrobial pesticide formulations applied to food-contact surfaces in public eating places, dairy-processing equipment, and food-processing equipment and utensils. This limitation will be enforced through the pesticide registration process under the Federal Insecticide, Fungicide, and Rodenticide Act (“FIFRA”), 7 U.S.C. 136 
                    *et seq.*
                     EPA will not register any such antimicrobial pesticide formulation that exceeds 100 ppm of calcium sulfate when ready for use. VI. Conclusions Therefore, an exemption from the requirement of a tolerance is established under 40 CFR 180. 940(a) for calcium sulfate when used as an inert ingredient in antimicrobial formulations applied to food-contact surfaces in public eating places, dairy-processing equipment, and food-processing equipment and utensils limited to 100 ppm in the final formulation. VII. Statutory and Executive Order Reviews This action establishes a tolerance exemption 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). 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 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 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). 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 the 
                    **Federal Register**
                    . This action is not a “major rule” as defined by 5 U.S.C. 804(2). List of Subjects in 40 CFR Part 180 Environmental protection
