[EPA-HQ-OPP-2024-0190; FRL-12647-01-OCSPP]


Choline Chloride in Pesticide Formulations; 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 choline chloride (CASRN 67-48-1) when 
used as an inert ingredient (adjuvant) applied to or on animals. 
Stratacor, Inc. on behalf of Emery Olochemicals LLC, 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 choline chloride, when used in accordance with the 
terms of the exemption.

DATES: This regulation is effective April 7, 2025. Objections and 
requests for hearings must be received on or before June 6, 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).

ADDRESSES: The docket for this action, identified by docket 
identification (ID) number EPA-HQ-OPP-2024-0190, is available at 
https://www.regulations.gov. Additional information about dockets 
generally, along with instructions for visiting the

SUPPLEMENTARY INFORMATION:

I. Executive Summary

A. Does this action apply to me?

    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 applies to them. 
Potentially affected entities may include:
     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 
action to a particular entity, consult the person listed under FOR 
FURTHER INFORMATION CONTACT.

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(c)(2)(A)(i) 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.'' FFDCA section 408(c)(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. 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, among other things, ``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. 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.

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-
2024-0190 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 June 6, 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 Service and 
Filing'', 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/HomePage?ReadForm.
    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. If you wish to 
include CBI in your request, please follow the applicable instructions 
at https://www.epa.gov/dockets/commenting-epa-dockets#rules and clearly 
mark the information that you claim to be CBI. Information not marked 
confidential pursuant to 40 CFR part 2 may be disclosed publicly by EPA 
without prior notice.

II. Petition for Exemption

    In the Federal Register of July 1, 2024 (89 FR 54398, FRL-11682-05-
OCSPP), EPA issued a document pursuant to FFDCA section 408, 21 U.S.C. 
346a, announcing the filing of a pesticide petition (PP IN-11865) by 
Stratacor, Inc. (6 Christopher Court Novato, CA 94947) on behalf of 
Emery Olochemicals LLC (4900 Este Ave., Cincinnati, OH 45232). The 
petition requested that 40 CFR 180.930 be amended by establishing an 
exemption from the requirement of a tolerance for residues of choline 
chloride (CASRN 67-48-1) when used as an inert ingredient (adjuvant) in 
pesticide formulations applied to/on animals. That document referenced 
a summary of the petition prepared by Stratacor, Inc. on behalf of 
Emery Olochemicals LLC, the petitioner, which is available in the 
docket. There were no comments received in response to the notice of 
filing.

III. Inert Ingredient Definition

    Inert ingredients are all ingredients in the pesticide that are not 
active ingredients as defined in 40 CFR

[[Page 14913]]

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

    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 choline chloride including 
exposure resulting from the exemption established by this action. EPA's 
assessment of exposures and risks associated with choline chloride 
follows.

A. Toxicological Profile

    The Toxicological Profile of choline chloride remains unchanged 
from the Toxicological Profile in Unit IV. of the 2010 rulemaking (75 
FR 760, January 6, 2010) (FRL-8802-4). Choline chloride has low acute 
toxicity via the oral (LD50 > 3,150 mg/kg) route in rats and 
mice. No acute dermal toxicity study is available. However, an in vitro 
percutaneous absorption study using human skin showed a low potential 
for percutaneous absorption. No acute inhalation study is available; 
however, inhalation exposure is of low concern based on the low vapor 
pressure. It is slightly irritating to the skin and eye in rabbits. 
Choline chloride is not a sensitizer in guinea pigs.
    Systemic toxicity is low following exposure to choline chloride. No 
toxicity is seen up to 200 and 500 mg/kg/day in subchronic and chronic 
studies in mice and rats, respectively. No maternal or developmental 
toxicity is seen up to 1,250 mg/kg/day in a developmental toxicity 
study in mice. No reproduction toxicity study is available, but 
spermatogenesis was not affected up to 83 mg/kg/day (highest dose 
tested) in a study evaluating the effect of choline chloride on 
spermatogenesis in rats. It is not genotoxic, neurotoxic, immunotoxic 
nor carcinogenic.

B. Toxicological Points of Departure/Levels of Concern

    The Toxicological Points of Departure/Levels of Concern for choline 
chloride remain unchanged from the Toxicological Points of Departure/
Levels of Concern discussion in Unit IV. of the 2010 rulemaking. The 
toxicological database for choline chloride is adequate. No new 
toxicological data have been received by the Agency which might alter 
the conclusions presented in the 2009 risk assessment. Based on the low 
toxicity of choline chloride in the available studies, EPA has 
concluded that there are no toxicological endpoints of concern for the 
U.S. population, including infants and children. As part of its 
qualitative assessment, the Agency did not use safety factors for 
assessing risk, and no additional safety factor is needed for assessing 
risk to infants and children.

C. Exposure Assessment

    1. Dietary exposure. Dietary exposure to choline chloride may occur 
from eating foods treated with pesticide formulations containing this 
inert ingredient and drinking water containing runoff from soils 
containing the treated crops. However, no toxicological endpoints of 
concern were selected, and therefore, a quantitative dietary exposure 
assessment for choline chloride was not conducted.
    2. Residential exposure. The term ``residential exposure'' is used 
in this document to refer to non-occupational, non-dietary exposure 
(e.g., for lawn and garden pest control, indoor pest control, 
termiticides, and flea and tick control on pets). Although current uses 
of choline chloride can result in residential exposures, no 
toxicological endpoints were selected, and therefore, it is not 
necessary to conduct a quantitative assessment of residential exposures 
and risks.
    3. Cumulative effects from substances with a common mechanism of 
toxicity. FFDCA section 408(b)(2)(D)(v) 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 database, EPA has 
not found choline chloride to share a common mechanism of toxicity with 
any other substances, and choline chloride does not appear to produce a 
toxic metabolite produced by other substances. For the purposes of this 
tolerance exemption, therefore, EPA has assumed that choline chloride 
does 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/pesticide-science-and-assessing-pesticide-risks/cumulative-assessment-risk-pesticides.

D. Additional Safety Factor for the Protection of Infants and Children

    FFDCA section 408(b)(2)(C) 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 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.
    Based on an assessment of choline chloride EPA has concluded that 
there are no toxicological endpoints of concern for the U.S. 
population, including infants and children. Because there are no 
threshold effects associated with choline chloride, EPA conducted a 
qualitative assessment. As part of that assessment, the Agency did not 
use safety factors for assessing risk, and no additional safety factor 
is needed for assessing risk to infants and children.

E. Aggregate Risks and Determination of Safety

    Because no toxicological endpoints of concern were identified, EPA 
concludes that there is a reasonable certainty that no harm will result 
to the general population, or to infants and children from aggregate 
exposure to choline chloride residues.

F. 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.

[[Page 14914]]

V. Conclusions

    Therefore, an exemption from the requirement of a tolerance is 
established for residues of choline chloride (CASRN 67-48-1) when used 
as an inert ingredient (adjuvant) in pesticide formulations applied to 
animals under 40 CFR 180.930.

VI. Statutory and Executive Order Reviews

    Additional information about these statutes and Executive orders 
can be found at https://www.epa.gov/laws-regulations/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. 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.

C. 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.

D. 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.

E. 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.

F. 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.

G. 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 VI.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 tolerance actions 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 
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 the pesticide-specific registration 
review documents, located in each chemical docket at https://www.regulations.gov.

H. 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.

I. 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.

H. 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.

I. 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.

J. 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 does not meet the 
criteria set forth in 5 U.S.C. 804(2).
