[EPA-HQ-OPP-2020-0112; FRL-10015-69]

Thiamine Mononitrate; 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 thiamine mononitrate (CAS Reg. No. 532-
43-4) when used as an inert ingredient (enzyme cofactor) in pesticide 
products applied to/on all growing crops pre-harvest, limited to 0.1% 
(by weight) in pesticide formulations. SciReg, Inc on behalf of 
Valagro, S.p.A submitted a petition to EPA under the Federal Food, 
Drug, and Cosmetic Act (FFDCA), requesting an establishment of an 
exemption from the requirement of a tolerance. This regulation 
eliminates the need to establish a maximum permissible level for 
residues of thiamine mononitrate when used in accordance with this 
exemption. Vitamin B1 is also known as thiamine mononitrate. Throughout 
this document and for purposes of issuing the tolerance, EPA is using 
the name ``thiamine mononitrate'' to be consistent with standard agency 
nomenclature for the identification of this substance.

DATES: This regulation is effective November 5, 2020. Objections and 
requests for hearings must be received on or before January 4, 2021 and 
must be filed in accordance with the instructions provided in 40 CFR 
part 178 (see also Unit I.C. of the SUPPLEMENTARY INFORMATION).

II. Petition for Exemption

    In the Federal Register of May 8, 2020 (85 FR 27346) (FRL-10008-
38), EPA issued a document pursuant to FFDCA section 408, 21 U.S.C. 
346a, announcing the filing of a pesticide petition (IN-11370) by 
SciReg, Inc (12733 Director's Loop, Woodbridge, VA 22192) on behalf of 
Valagro S.p.A. (Zona Industriale, Via Cagliari, 1, 66041 Atessa (CH), 
Italy). The petition requested that 40 CFR be amended by establishing 
an exemption from the requirement of a tolerance for residues of 
vitamin B1 (thiamine mononitrate, CAS Reg. No. 532-43-4) when used as 
an inert ingredient (enzyme cofactor) in pesticide products applied to/
on all growing crops pre- harvest under 40 CFR 180.920, limited to 0.1% 
(by weight) in pesticide formulations. That document referenced a 
summary of the petition prepared by SciReg, Inc on behalf of Valagro, 
S.p.A, the petitioner, which is available in the docket, http://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 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 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. Under FFDCA section 408(c)(2)(B), EPA must take 
into account, among other considerations, the factors in subparagraphs 
(C) and (D) of subsection (b)(2). 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 appreciable risks 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 thiamine mononitrate including 
exposure resulting from the exemption established by this action. EPA's 
assessment of exposures and risks associated with thiamine mononitrate 
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 thiamine mononitrate 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 
http://www.regulations.gov in the document Thiamine Mononitrate, 
Vitamin B1--Human Health Risk and Ecological Effects Assessment of 
Request to Amend an Existing Exemption from the Requirements of a 
Pesticide Tolerance Under 40 CFR 180.920 for Food Use Inert Ingredient 
in docket ID number EPA-HQ-OPP-2020-0112.
    The acute oral toxicity is low in mice treated with thiamine 
mononitrate. It is mildly to irritating to the rabbit eye and not 
irritating to rabbit skin. Thiamine mononitrate is a sensitizer.
    No toxicity is observed in repeated dose studies conducted with 
thiamine mononitrate administered via diet and gavage to rats and mice. 
Fetal susceptibility is not observed in the reproduction and 
developmental toxicity studies in rats. No adverse effects are observed 
in parents, offspring

[[Page 70496]]

or reproduction in rats treated with thiamine mononitrate at doses up 
to 100 mg/kg/day. There is no concern for reproduction or developmental 
toxicity since metabolism studies indicate that thiamine mononitrate 
absorption declines for an intake higher than 5 mg/day and absorbed 
thiamine mononitrate is actively excreted in the urine.
    Mutagenicity is not expected with thiamine mononitrate based on 
available mutagenicity studies. Thiamine mononitrate is not expected to 
be carcinogenic based on studies in mice.
    Neurotoxicity and immunotoxicity studies are not available for 
review. However, no evidence of neurotoxicity or immunotoxicity is 
observed in any of the available studies on thiamine mononitrate.

B. Toxicological Points of Departure/Levels of Concern

    The available toxicity studies indicate that thiamine mononitrate 
has very low oral toxicity. An acute oral toxicity study shows the 
lethal dose (LD)50 above 5,000 mg/kg in mice. Repeated dose 
studies show no toxicity at doses up to 1,500 mg/kg/day. Since no 
toxicity is observed, an endpoint of concern for risk assessment 
purposes was not identified. EPA assessed dietary and other non-
occupational exposures qualitatively.

C. Exposure Assessment

    1. Dietary exposure from drinking water, food and feed uses. In 
evaluating dietary exposure to thiamine mononitrate, EPA considered 
exposure under the proposed exemption from the requirement of a 
tolerance. EPA assessed dietary exposures from thiamine mononitrate in 
food as follows:
    Dietary exposure (food and drinking water) to thiamine mononitrate 
may occur following ingestion of foods with residues from their use in 
accordance with this exemption. Dietary exposure may also occur from 
its presence naturally in food, its use as a dietary supplement, and as 
a direct food additive. 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).
    Thiamine mononitrate may be used in pesticide products and non-
pesticide products that may be used in and around the home. Thiamine 
mononitrate may also be found in cosmetics and personal care products. 
Based on the discussion above regarding the toxicity of the thiamine 
mononitrate, a quantitative residential exposure assessment for 
thiamine mononitrate was not conducted.
    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 available data, thiamine mononitrate does not have a 
toxic mechanism; therefore, section 408(b)(2)(D)(v) does not apply.

D. Safety Factor 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 thiamine mononitrate. 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 thiamine mononitrate, 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

    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 thiamine mononitrate residues.

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 
thiamine mononitrate in or on any food commodities. EPA is establishing 
limitations on the amount of thiamine mononitrate that may be used in 
pesticide formulations applied pre-harvest. These limitations 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 pesticide formulation for food use 
that exceeds 0.1% by weight of thiamine mononitrate in the final 
pesticide formulation.

VI. Conclusions

    Therefore, an exemption from the requirement of a tolerance is 
established for residues of thiamine mononitrate (CAS Reg. No. 532-43-
4) when used as inert ingredients (enzyme cofactor) in pesticide 
products applied to/on all growing crops pre-harvest under 40 CFR 
180.920, limited to 0.1% (by weight) in pesticide formulations.

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), nor is it considered a 
regulatory action under Executive Order 13771, entitled ``Reducing 
Regulations and Controlling Regulatory Costs'' (82 FR 9339, February 3, 
2017). 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

[[Page 70497]]

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).
