# Priestia megaterium
strain SYM36613; exemption from the requirement of a tolerance.
**AGENCY:**
Environmental Protection Agency (EPA).
**ACTION:**
Final rule.
**SUMMARY:**
This regulation establishes an exemption from the requirement of a tolerance for residues of *Priestia megaterium* strain SYM36613, formerly *Bacillus aryabhattai* strain SYM36613 ( *P. megaterium* strain SYM36613) in or on all food commodities when used in accordance with label directions and good agricultural practices. Indigo Ag, Inc. submitted a petition to EPA under the Federal Food, Drug, and Cosmetic Act (FFDCA), requesting an exemption from the requirement of a tolerance. This regulation eliminates the need to establish a maximum permissible level for residues of *P. megaterium* strain SYM36613 under FFDCA when used in accordance with this exemption.
**DATES:**
This regulation is effective October 31, 2025. Objections and requests for hearings must be received on or before December 30, 2025 and must be filed in accordance with the instructions provided in 40 CFR part 178 (see also Unit I.C. of the *SUPPLEMENTARY INFORMATION* ).

**B. What is EPA's authority for taking this action?**
EPA is issuing this rulemaking under section 408 of the Federal Food, Drug, and Cosmetic Act (FFDCA), 21 U.S.C. 346a. 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 . . .”
**C. How can I file an objection or hearing request?**
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 docket ID number EPA-HQ-OPP-2023-0621 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 December 30, 2025.
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. *See* “Revised Order Urging Electronic Filing and Service,” dated June 22, 2023, which can be found at *https://www.epa.gov/system/files/documents/2023-06/2023-06-22%20-%20revised%20order%20urging%20electronic%20filing%20and%20service.pdf.* Although EPA's regulations require submission via U.S. Mail or hand delivery, EPA intends to treat submissions filed via electronic means as properly filed submissions; therefore, 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 *https://yosemite.epa.gov/oa/eab/eab-alj_upload.nsf.*
In addition to filing an objection or hearing request with the Hearing Clerk as described in 40 CFR part 178, please submit a copy of the filing (excluding any Confidential Business Information (CBI)) for inclusion in the public docket at *https://www.regulations.gov.* Follow the online instructions for submitting comments. Do not submit electronically any information you consider to be CBI or other information whose disclosure is restricted by statute.

Information not marked confidential pursuant to 40 CFR part 2 may be disclosed publicly by EPA without prior notice.
**II. Petitioned for Exemption**
In the *Federal Register* of February 9, 2024 (89 FR 9104) (FRL-10579-12-OCSPP), EPA issued a notice pursuant to FFDCA section 408(d)(3), 21 U.S.C. 346a(d)(3), announcing the filing of a pesticide tolerance exemption petition (PP 3F9071) by Indigo Ag, Inc., 500 Rutherford Ave., Charlestown, MA 02129. The petition requested that 40 CFR part 180 be amended by establishing an exemption from the requirement of a tolerance for residues of the fungicide *P. megaterium* strain SYM36613 in or on all food commodities. That notice referenced a summary of the petition prepared by the petitioner Indigo Ag, Inc. and available in the docket via *https://www.regulations.gov.* EPA received no comments in response to the notice of filing.
Based upon review of data and other information supporting the petition, EPA modified the active ingredient name from *Bacillus aryabhattai* strain SYM36613 to *Priestia megaterium* strain SYM36613.
**III. Final Tolerance Actions**
**A. EPA's Safety Determination**
EPA evaluated the available toxicological and exposure data on *P. megaterium* strain SYM36613 and considered their validity, completeness, and reliability, as well as the relationship of this information to human risk. A full explanation of the data upon which EPA relied and its risk assessment based on those data can be found within the document entitled “Human Health Risk Assessment of *Priestia* (formerly *Bacillus* ) *megaterium (formerly aryabhattai)* strain SYM36613, a New Active Ingredient, in [ *Priestia megaterium* strain SYM36613 MUP (Manufacturing-use Product)] and Indigo® 398 FP and Indigo® 398 WD (End-use Products)] Proposed for Registration and an Associated Petition Requesting a Tolerance Exemption,” or the *P. megaterium* strain SYM36613 Human Health Risk Assessment. This document, as well as other relevant information, is available in the docket for this action as described under *ADDRESSES* .
The toxicological profile of *P. megaterium* strain SYM36613 is described in the *P. megaterium* strain SYM36613 Human Health Risk Assessment. Based upon its evaluation, EPA concludes that with regards to humans, *P. megaterium* strain SYM36613 is not anticipated to be toxic, pathogenic, or infective. Significant dietary and non-occupational exposure to residues of *P. megaterium* strain SYM36613 are not expected as the products will only be applied in agricultural settings early in the growing season, will only be applied directly to soil and seed, and have not been approved for any residential uses. Other non-occupational exposure through drift or other means are also considered unlikely due to the low application rates proposed for end-use products that are not expected to significantly increase the levels of *P. megaterium* strain SYM36613 naturally present in the treated environment. If this active ingredient were to enter surface or ground water to some degree, it would likely be present at levels below that of the naturally occurring *P. megaterium* organism and it would be even further reduced in numbers by way of standard municipal drinking water practices. Even if dietary and non-occupational exposures to residues of *P. megaterium* strain SYM36613 were to occur, there are no risks of concern due to the lack of adverse effects from toxicity, pathogenicity, or infectivity of *P. megaterium* strain SYM36613 from the results of the guideline mammalian toxicology testing. Further, because food crops undergo postharvest washing, it is unlikely that significant residues of *P. megaterium* strain would remain on treated crops.
EPA determined that no additional margin of safety is necessary to protect infants and children as part of the qualitative assessment conducted, as data and rationale demonstrated that there are no threshold levels of concern with the toxicity, pathogenicity or infectivity of *P. megaterium* strain SYM36613.
Based upon its evaluation in the *P. megaterium* strain SYM36613 Human Health Risk Assessment, which concludes that there are no risks of concern from aggregate exposure to *P. megaterium* strain SYM36613, EPA concludes that there is a reasonable certainty that no harm will result to the U.S. population, including infants and children, from aggregate exposure to residues of *P. megaterium* strain SYM36613.
**B. Analytical Enforcement Methodology**
An analytical method is not required for *P. megaterium* strain SYM36613 because EPA is establishing an exemption from the requirement of a tolerance without any numerical limitation.
**C. Conclusion**
Therefore, an exemption from the requirement of a tolerance is established for residues of *P. megaterium* strain SYM36613 in or on all food commodities when used in accordance with label directions and good agricultural practices.
**IV. Statutory and Executive Order Reviews**
Additional information about these statutes and Executive Orders can be found at *https://www.epa.gov/laws-regulations/laws-and-executive-orders.*
**A. Executive Order 12866: Regulatory Planning and Review**
This action is exempt from review under Executive Order 12866 (58 FR 51735, October 4, 1993), because it establishes or modifies a pesticide tolerance or a tolerance exemption under FFDCA section 408 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.
**B. Executive Order 14192: Unleashing Prosperity Through Deregulation**
Executive Order 14192 (90 FR 9065, February 6, 2025) does not apply because actions that establish a tolerance exemption under FFDCA section 408 are exempted from review under Executive Order 12866.
**C. Paperwork Reduction Act (PRA)**
This action does not impose an information collection burden under the PRA, 44 U.S.C. 3501 *et seq.,* because it does not contain any information collection activities.
**D. Regulatory Flexibility Act (RFA)**
This action is not subject to the RFA, 5 U.S.C. 601 *et seq.* The RFA applies only to rules subject to notice and comment rulemaking requirements under the Administrative Procedure Act (APA), 5 U.S.C. 553, or any other statute. This rule is not subject to the APA but is subject to FFDCA section 408(d), which does not require notice and comment rulemaking to take this action in response to a petition.
**E. Unfunded Mandates Reform Act (UMRA)**
This action does not contain an unfunded mandate of $100 million or more (in 1995 dollars and adjusted annually for inflation) as described in UMRA, 2 U.S.C. 1531-1538, and does not significantly or uniquely affect small governments. The action imposes no enforceable duty on any State, local or Tribal governments or the private sector.
**F. Executive Order 13132: Federalism**
This action does not have federalism implications as specified in Executive Order 13132 (64 FR 43255, August 10, 1999), because it will not have substantial direct effects on the States, on the relationship between the National Government and the States, or on the distribution of power and responsibilities among the various levels of government.
**G. Executive Order 13175: Consultation and Coordination With Indian Tribal Governments**
This action does not have tribal implications as specified in Executive Order 13175 (65 FR 67249, November 9, 2000), because it will not have substantial direct effects on tribal governments, on the relationship between the Federal Government and the Indian Tribes, or on the distribution of power and responsibilities between the Federal Government and Indian Tribes.
**H. Executive Order 13045: Protection of Children From Environmental Health Risks and Safety Risks**
This action is not subject to Executive Order 13045 (62 FR 19885, April 23, 1997) because it is not a significant regulatory action under section 3(f)(1) of Executive Order 12866 (See Unit IV.A.), and because EPA does not believe the environmental health or safety risks addressed by this action present a disproportionate risk to children.
However, EPA's 2021 Policy on Children's Health applies to this action. This rule finalizes an exemption from the requirement of a tolerance under the FFDCA, which requires EPA to give special consideration to exposure of infants and children to the pesticide chemical residue in establishing a tolerance exemption 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. . . .” (FFDCA 408(b)(2)(C)). The Agency's consideration is documented in Unit III.A.
**I. Executive Order 13211: Actions Concerning Regulations That Significantly Affect Energy Supply, Distribution or Use**
This action is not subject to Executive Order 13211 (66 FR 28355) (May 22, 2001) because it is not a significant regulatory action under Executive Order 12866.
**J. National Technology Transfer Advancement Act (NTTAA)**
This action does not involve technical standards that would require Agency consideration under NTTAA section 12(d), 15 U.S.C. 272.
**K. Congressional Review Act (CRA)**
This action is subject to the CRA, 5 U.S.C. 801 *et seq.,* and EPA will submit a rule report to each House of the Congress and to the Comptroller General of the United States. This action not a “major rule” as defined by 5 U.S.C. 804(2).
