Executive Summary</HD> <HD SOURCE="HD2">A. Does this action apply to me?</HD> You may be potentially affected by this action if you are an agricultural producer, food manufacturer, or pesticide manufacturer. The following list of North American Industrial Classification System (NAICS) codes is not intended to be exhaustive, but rather provides a guide to help readers determine whether this document might apply to them: • Crop production (NAICS code 111). • Animal production (NAICS code 112). • Food manufacturing (NAICS code 311). • Pesticide manufacturing (NAICS code 32532). If you have any questions regarding the applicability of this proposed action to a particular entity, consult the person listed under <E T="02">FOR FURTHER INFORMATION CONTACT</E> . <HD SOURCE="HD2">B. What action is the Agency taking?</HD> EPA is finalizing several tolerance actions that the Agency proposed in the <E T="04">Federal Register</E> of September 6, 2024 (89 FR 72775 (FRL-12177-01-OCSPP)), because EPA previously determined these tolerance actions were necessary or appropriate during registration review of the pesticide active ingredients identified in Unit III. of this final rule. The tolerance actions for each pesticide active ingredient are described in Unit III. of the proposed rule and may include but are not limited to the following types of actions: • Revising tolerance expressions; • Modifying commodity definitions; • Updating crop groupings; • Removing expired tolerances; • Revoking tolerances that are no longer needed; and • Harmonizing tolerances with the Codex Alimentarius Commission (Codex) Maximum Residue Levels (MRLs). As indicated in the proposed rule, this final rule may reflect the Agency's 2019 adoption of the Organization of Economic Cooperation and Development (OECD) Rounding Class Practice. More information on the OECD Rounding Class Practice can be found at <E T="03">https://one.oecd.org/document/ENV/JM/MONO(2011)2/en/pdf.</E> Where applicable, these adjustments for specific pesticides are reflected in the final regulatory text. <HD SOURCE="HD2">C. What is EPA's authority for taking this action?</HD> FFDCA section 408(e), 21 U.S.C. 346a(e), authorizes EPA to establish, modify, or revoke tolerances or exemptions from the requirement of a tolerance on its own initiative. After providing a 60-day public comment period, EPA may finalize the rule. EPA provided a 60-day comment period and is now finalizing the rule. FFDCA section 408(b)(2)(A)(i) 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.” FFDCA section 408(b)(2)(A)(ii) 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. FFDCA section 408(b)(2)(C) 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 . . . .” Under FIFRA section 3(g), 7 U.S.C. 136a(g), EPA is required to periodically review all registered pesticides and determine if those pesticides continue to meet the standard for registration under FIFRA. To learn more about the registration review, please see Unit II.C. of the proposed rule “Pesticide Tolerances; Implementing Registration Review Decisions for Certain Pesticides (Capric (Decanoic) Acid, Caprylic (Octanoic) Acid, and Pelargonic (Nonanoic) Acid)” (89 FR 72775, September 6, 2024 (FRL-12177-01-OCSPP)). <HD SOURCE="HD2">D. How can I file an objection or hearing request?</HD> Under FFDCA section 408(g), 21 U.S.C. 346a(g), any person may file an objection to any aspect of this regulation and may also request a hearing on those objections. If you fail to file an objection to the final rule within the time period specified in the final rule, you will have waived the right to raise any issues resolved in the final rule. You must file your objection or request a hearing on this regulation in accordance with the instructions provided in 40 CFR part 178. To ensure proper receipt by EPA, you must identify the chemical specific docket ID number as provided in Unit III. in the subject line on the first page of your submission. All objections and requests for a hearing must be in writing and must be received by the Hearing Clerk on or before August 11, 2025. The EPA's Office of Administrative Law Judges (OALJ), in which the Hearing Clerk is housed, urges parties to file and serve documents by electronic means only, notwithstanding any other particular requirements set forth in other procedural rules governing those proceedings. <E T="03">See</E> “Revised Order Urging Electronic Filing and Service,” dated June 22, 2023, which can be found at <E T="03">https://www.epa.gov/system/files/documents/2023-06/2023-06-22%20-%20revised%20order%20urging%20electronic%20filing%20and%20service.pdf.</E> Although the EPA's regulations require submission via U.S. Mail or hand delivery, the EPA intends to treat submissions filed via electronic means as properly filed submissions; therefore, the EPA believes the preference for submission via electronic means will not be prejudicial. When submitting documents to the OALJ electronically, a person should utilize the OALJ e-filing system at <E T="03">https://yosemite.epa.gov/oa/eab/eab-alj_upload.nsf.</E> <HD SOURCE="HD1">II. Background</HD> In the <E T="04">Federal Register</E> of September 6, 2024 (89 FR 72775 (FRL-12177-01-OCSPP)), EPA proposed several tolerance actions to amend established tolerance exemptions for capric (decanoic) acid, caprylic (octanoic) acid, and pelargonic (nonanoic) acid. The Agency previously determined in a March 2022 Combined Preliminary Work Plan/Proposed Interim Decision that these amendments were necessary or appropriate during registration review of these pesticide active ingredients. For additional background information, see Unit II. of the proposed rule. EPA received six comments in response to the proposed rule. Two comments were in support of the Agency action (see <E T="03">https://www.regulations.gov</E> for public comments identified as Document ID Nos. EPA-HQ-OPP-2023-0454-0003 and EPA-HQ-OPP-2023-0454-0007). Four comments suggested EPA eliminate redundancies but maintain tolerances on capric acid, caprylic acid, and pelargonic acid, either at the existing level or consistent with global tolerance levels (see public comments identified as Document ID Nos. EPA-HQ-OPP-2023-0454-0002, EPA-HQ-OPP-2023-0454-0004, EPA-HQ-OPP-2023-0454-0005, and EPA-HQ-OPP-2023-0454-0006). These commenters noted general concerns that consumers may assume foods are free of pesticides, that there is a potential for consumption in large quantities, and that there may be unknown long-term effects. The existing legal framework provided by section 408 of the FFDCA authorizes EPA to establish tolerances when it determines that the tolerance is safe. Upon consideration of the validity, completeness, and reliability of the available data as well as other factors that the FFDCA requires EPA to consider, EPA has determined that these exemptions from the requirement of a tolerance are safe.
