###### Environmental Protection Agency

          - 40 CFR Part 180
          - [EPA-HQ-OPP-2021-0551; FRL-9348-01-OCSPP]

# AGENCY:

Environmental Protection Agency (EPA).

# ACTION:

Final rule.

# SUMMARY:

This regulation amends an exemption from the requirement of a tolerance for residues of tetraacetylethylenediamine (TAED) and its metabolite diacetylethylenediamine (DAED) by expanding its use in or on all food commodities, when used as a fungicide and bactericide in accordance with label directions and good agricultural practices. The Lubrizol Corporation, 29400 Lakeland Blvd., Wickliffe, OH 44092, submitted a petition, pursuant to section 408(d) of the Federal Food, Drug, and Cosmetic Act (FFDCA), 21 U.S.C. 346a(d), to amend 40 CFR 180.1327. 40 CFR 180.1327 currently provides for an exemption from the requirement of a tolerance for residues of the pesticide, tetraacetylethylenediamine (TAED), and its metabolite diacetylethylenediamine (DAED), in or on rice and strawberries, when used as a fungicide and bactericide in accordance with label directions and good agricultural practices. This regulation eliminates the need to establish a maximum permissible level for residues of tetraacetylethylenediamine (TAED) or its metabolite diacetylethylenediamine (DAED) when used in accordance with this exemption.

# DATES:

                        This regulation is effective March 17, 2022.

## II. Background and Statutory Findings

                    In the                     **Federal Register**                     of September 22, 2021 (86 FR 52624) (FRL-8792-03-OCSPP), EPA issued a document pursuant to FFDCA section 408(d)(3), 21 U.S.C. 346a(d)(3), announcing the filing of a pesticide tolerance petition (PP 9F8781) by The Lubrizol Corporation, 29400 Lakeland Blvd., Wickliffe, OH, 44092. The petition requested that 40 CFR 180.1327 be amended by amending the existing exemption from the requirement of a tolerance for residues of tetraacetylethylenediamine (TAED) and its metabolite diacetylethylenediamine (DAED) by expanding it to in or on all food commodities, when used as a fungicide and bactericide in accordance with label directions and good agricultural practices. That document referenced a                           ( print page 15098)                        summary of the petition prepared by the petitioner, The Lubrizol Corporation, which is available in the docket,                     *https://www.regulations.gov.*                     There were no comments received in response to the notice of filing.                

## III. 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 exemption 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. Pursuant to FFDCA section 408(c)(2)(B), in establishing or maintaining in effect an exemption from the requirement of a tolerance, EPA must take into account the factors set forth in FFDCA section 408(b)(2)(C), which require 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. . . .” Additionally, FFDCA section 408(b)(2)(D) requires that 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 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. 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 pesticide chemical residue, 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 TAED and DAED including exposure resulting from the exemption established by this action. EPA's assessment of exposures and risks associated with TAED and DAED follows.

### A. Toxicological Profile

TAED is an analiphatic amide that is approved as a pesticide active ingredient for food and non-food uses. It is also is listed by the Food and Drug Administration (FDA) for use as a bleaching agent in the manufacture of food-contact paper and paperboard products (21 CFR 176.170).

TAED rapidly degrades to form diacetylethylenediamine (DAED), peroxyacetic acid (PAA), and hydrogen peroxide when exposed to water. DAED is considered to be of similar or less toxicity than TAED. Hydrogen peroxide and peroxyacetic acid are exempt from the requirement of a tolerance under 40 CFR 180.1197 and 180.1196(c), respectively. Food uses for TAED in or on rice and strawberries are supported by 40 CFR 180.1327, which currently provides for an exemption from the requirement of a tolerance for residues TAED and DAED in or on rice and strawberries, when used as a fungicide and bactericide in accordance with label directions and good agricultural practices. As a non-food pesticidal use, TAED is used on various non-bearing fruit trees, ornamentals and grasses. For all uses, dietary exposure to TAED is expected to be minimal due to TAED's physical and chemical properties and ready biodegradation in the environment.

With regard to the overall toxicological profile, TAED is of minimal toxicity. Based on acute studies, TAED is of low acute oral toxicity and acute inhalation toxicity (Toxicity Category IV), low acute dermal toxicity (Toxicity Category III) and is non-irritating to the skin and eye (Toxicity Category IV). The chemical is not a skin sensitizer. DAED is considered to be of similar or less toxicity than TAED. All data requirements were satisfied by guideline studies for subchronic toxicity (90-day oral, 90-day inhalation and 90-day dermal), developmental toxicity, reproductive toxicity and mutagenicity data requirements. There were no adverse subchronic effects for any oral or dermal routes of exposure. The active ingredient was determined to be non-mutagenic, and no adverse effects were identified relative to either developmental toxicity or reproductive toxicity. Based on this toxicological profile, EPA did not identify any toxicological endpoints of concern for TAED.

### B. Toxicological Points of Departure/Levels of Concern

No toxicological endpoint of concern has been identified for TAED or DAED.

### C. Exposure Assessment

                    1.                     *Dietary exposure from food, feed uses, and drinking water.*                     As part of its qualitative risk assessment for TAED, the Agency considered the potential for dietary exposure to residues of TAED and its degradate, DAED. EPA concludes that dietary (food and drinking water) exposures are likely to be negligible, due to the short half-life and biodegradable nature of TAED and DAED. Further, biodegradation of TAED and DAED yields the products water, nitrate, and ammonia, which are all found naturally in the environment and readily metabolized by microorganisms.                

                    2.                     *From non-dietary exposure.*                     A revaluation of the risk of occupational and residential (non-dietary) exposure to TAED and DAED was not conducted at this time. Previous EPA risk assessments support the uses on currently approved TAED product labels.                

                    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 that TAED or DAED share a common mechanism of toxicity with any other substances, and they do not appear to produce a toxic metabolite produced by other substances. For the purposes of this tolerance action, therefore, EPA has assumed TAED and DAED do 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 website at                     *https://www.epa.gov/​pesticides/​cumulative.*

### D. Safety Factor for Infants and Children

                    FFDCA Section 408(b)(2)(C) provides that EPA shall retain 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                           ( print page 15099)                        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. An FQPA safety factor is not required at this time for TAED and its metabolite, DAED, because EPA has conducted a qualitative dietary assessment based on low toxicity and anticipated negligible exposure to the active ingredient.                

### E. Aggregate Risk

Based on the available data and information, the EPA has concluded that a qualitative aggregate risk assessment is appropriate to support the pesticidal use of TAED and its metabolite, DAED, and that risks of concern are not anticipated from aggregate exposure to the substance or its metabolite, DAED. This conclusion is based on the low toxicity of the active ingredient and expected rapid degradation of TAED and DAED in the environment.

                    A full explanation of the data upon which EPA relied and its risk assessment based on those data can be found within the July 22, 2021, document entitled “Human Health Dietary Risk Assessment to Support a Tolerance Exemption Amendment for Warwick AG610 (EPA Reg. No. 59825-6), Containing 92% Tetraacetylethylenediamine as its Active Ingredient.” This document, as well as other relevant information, is available in the docket for this action as described under                     **ADDRESSES**                    .                

## IV. Determination of Safety for U.S. Population, Infants and Children

Based on the Agency's assessment, EPA concludes that there is reasonable certainty that no harm will result to the U.S. population, including infants and children, from aggregate exposure to residues of TAED.

## 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 Nations 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 an MRL for tetraacetylethylenediamine (TAED) or its metabolite diacetylethylenediamine (DAED).

## VI. Conclusions

Therefore, EPA is amending the currently established exemption for residues of tetraacetylethylenediamine (TAED) and its metabolite diacetylethylenediamine (DAED) to include use in or on all food commodities—no longer limiting food use to strawberries and rice, when used as a fungicide and bactericide in accordance with label directions and good agricultural practices.

## VII. Statutory and Executive Order Reviews

                    This action amends 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 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 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).
