Abstract
This regulation establishes an exemption from the requirement of a tolerance for residues of iron oxide (Fe<INF>3</INF>O<INF>4</INF>) (CAS Reg. No. 1317-61-9) when used as an inert ingredient (colorant) in pesticide formulations applied to animals. The United States Department of Agriculture (USDA) Animal and Plant Health Inspection Service submitted a petition (IN-11661) to EPA under the Federal Food, Drug, and Cosmetic Act (FFDCA), requesting establishment of an exemption from the requirement of a tolerance. This regulation eliminates the need to establish a maximum permissible level for residues of iron oxide (Fe<INF>3</INF>O<INF>4</INF>), when used in accordance with the terms of that exemption.

II. Petition for Exemption
In the Federal Register of March 22, 2022 (87 FR 16133) (FRL-9410-
11-OCSPP), EPA issued a document pursuant to FFDCA section 408, 21
U.S.C. 346a, announcing the filing of a pesticide petition (PP IN-
11661) by the USDA Animal and Plant Health Inspection Service, 4700
River Road, Unit 149, Riverdale, MD 20737. The petition requested that
40 CFR 180.930 be amended by establishing an exemption from the
requirement of a tolerance for residues of iron oxide
(Fe<INF>3</INF>O<INF>4</INF>) (CAS Reg. No. 1317-61-9) when used as an
inert ingredient (colorant) in pesticide formulations at no more than
2,000 parts per million (ppm) (0.2% by weight) in the final formulation
applied to animals. That document referenced a summary of the petition
prepared by the USDA Animal and Plant Health Inspection Service, the
petitioner, which is available in the docket, <a href="https://www.regulations.gov">https://www.regulations.gov</a>. 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 tolerance 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. When making a safety determination for an
exemption for the requirement of a tolerance, FFDCA section
408(c)(2)(B) directs EPA to consider the considerations in section
408(b)(2)(C) and (D). 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. . . .'' Section 408(b)(2)(D) lists other factors for EPA
consideration making safety determinations, e.g., the validity,
completeness, and reliability of available data, nature of toxic
effects, available information concerning the cumulative effects of the
pesticide chemical and other substances with a common mechanism of
toxicity, and available information concerning aggregate exposure
levels to the pesticide chemical and other related substances, among
others.
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.
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 iron oxide
(Fe<INF>3</INF>O<INF>4</INF>) including exposure resulting from the
exemption established by this action. EPA's assessment of exposures and
risks associated with iron oxide (Fe<INF>3</INF>O<INF>4</INF>) 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 iron oxide
(Fe<INF>3</INF>O<INF>4</INF>) as well as the no-observed-adverse-
effect-level (NOAEL) and the lowest-observed-adverse-effect-level
(LOAEL) from the toxicity studies are discussed in this unit.
The toxicological database of iron oxide
(Fe<INF>3</INF>O<INF>4</INF>) is supported by data regarding iron oxide
red and iron oxide yellow. EPA has determined that it is appropriate to
bridge iron oxide red and iron oxide yellow data to assess iron oxide
(Fe<INF>3</INF>O<INF>4</INF>) due to similarities in structure, and
similarities among the
[[Page 78560]]
available human health toxicity data of these substances.
Iron oxide (Fe<INF>3</INF>O<INF>4</INF>) exhibits low levels of
acute toxicity via the oral and inhalation routes of exposure and is
anticipated to have low acute dermal toxicity. It is not a skin or eye
irritant nor a skin sensitizer. No adverse effects were reported in the
90-day study in rats. No evidence of neurotoxicity was observed in the
neurotoxicity screening performed in the 90-day oral rat study, and no
evidence of immunotoxicity was seen in the available studies. No
adverse reproduction or developmental effects were reported in the
available reproduction and developmental toxicity study summaries in
rats. Furthermore, concern for carcinogenicity is low, based on
negative results in a mutagenicity study, and the lack of structural
alerts for mutagenicity or carcinogenicity.
B. Toxicological Points of Departure/Levels of Concern
Once a pesticide's toxicological profile is determined, EPA
identifies toxicological points of departure (POD) and levels of
concern to use in evaluating the risk posed by human exposure to the
pesticide. For hazards that have a threshold below which there is no
appreciable risk, the toxicological POD is used as the basis for
derivation of reference values for risk assessment. PODs are developed
based on a careful analysis of the doses in each toxicological study to
determine the dose at which no adverse effects are observed (the NOAEL)
and the lowest dose at which adverse effects of concern are identified
(the LOAEL). Uncertainty/safety factors are used in conjunction with
the POD to calculate a safe exposure level--generally referred to as a
population-adjusted dose (PAD) or a reference dose (RfD)--and a safe
margin of exposure (MOE). For non-threshold risks, the Agency assumes
that any amount of exposure will lead to some degree of risk. Thus, the
Agency estimates risk in terms of the probability of an occurrence of
the adverse effect expected in a lifetime. For more information on the
general principles EPA uses in risk characterization and a complete
description of the risk assessment process, see <a href="https://www.epa.gov/pesticide-science-and-assessing-pesticide-risks/overview-risk-assessment-pesticide-program">https://www.epa.gov/pesticide-science-and-assessing-pesticide-risks/overview-risk-assessment-pesticide-program</a>.
The hazard profile of iron oxide (Fe<INF>3</INF>O<INF>4</INF>) is
adequately defined. Overall, iron oxide (Fe<INF>3</INF>O<INF>4</INF>)
is of low acute, subchronic, and developmental toxicity. No systemic
toxicity is observed up to 1,000 mg/kg/day. Since signs of toxicity
were not observed, no toxicological endpoints of concern or PODs were
identified. Therefore, a qualitative risk assessment for iron oxide
(Fe<INF>3</INF>O<INF>4</INF>) can be performed.
C. Exposure Assessment
1. Dietary exposure from food and feed uses and drinking water. In
evaluating dietary exposure to iron oxide
(Fe<INF>3</INF>O<INF>4</INF>), EPA considered exposure under the
proposed exemption from the requirement of a tolerance. EPA assessed
dietary exposures from iron oxide (Fe<INF>3</INF>O<INF>4</INF>) in food
as follows:
Dietary exposure to iron oxide (Fe<INF>3</INF>O<INF>4</INF>) may
occur from consuming game treated with pesticide formulations (baits)
containing this inert ingredient and from non-pesticidal uses (food
additive uses and inactive ingredient uses in FDA-approved drugs).
Exposure to iron oxide (Fe<INF>3</INF>O<INF>4</INF>) via drinking water
is expected to be negligible, based on the limited use pattern (baits).
However, no toxicological endpoints of concern were selected, and
therefore, a quantitative dietary exposure assessment for iron oxide
(Fe<INF>3</INF>O<INF>4</INF>) was not conducted.
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).
No residential exposure is anticipated from the proposed uses for
iron oxide (Fe<INF>3</INF>O<INF>4</INF>) in pesticide formulation
applied to animals. Iron oxide (Fe<INF>3</INF>O<INF>4</INF>) may be
present in current pesticide and non-pesticide products that may be
used in and around the home. However, a quantitative residential
exposure assessment was not conducted since a toxicological endpoint
for risk assessment was not identified.
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 lack of toxicity in the available database, EPA has
not found iron oxide (Fe<INF>3</INF>O<INF>4</INF>) to share a common
mechanism of toxicity with any other substances, and iron oxide
(Fe<INF>3</INF>O<INF>4</INF>) does not appear to produce a toxic
metabolite produced by other substances. For the purposes of this
tolerance exemption, therefore, EPA has assumed that iron oxide
(Fe<INF>3</INF>O<INF>4</INF>) 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
<a href="https://www.epa.gov/pesticide-science-and-assessing-pesticide-risks/cumulative-assessment-risk-pesticides">https://www.epa.gov/pesticide-science-and-assessing-pesticide-risks/cumulative-assessment-risk-pesticides</a>.
D. Additional Safety Factor for the Protection of Infants and Children
Section 408(b)(2)(C) of FFDCA 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 Food Quality Protection Act
(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 available data for iron oxide
(Fe<INF>3</INF>O<INF>4</INF>), 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 iron oxide (Fe<INF>3</INF>O<INF>4</INF>), 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 iron oxide (Fe<INF>3</INF>O<INF>4</INF>) 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
iron oxide (Fe<INF>3</INF>O<INF>4</INF>) in or on any food commodities.
EPA is establishing a limitation on the amount of iron oxide
(Fe<INF>3</INF>O<INF>4</INF>) that may be used in pesticide
formulations applied to animals. This limitation will be enforced
through the pesticide registration process under the Federal
[[Page 78561]]
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 0.2% iron oxide (Fe<INF>3</INF>O<INF>4</INF>) in the final
pesticide formulation.
VI. Conclusions
Therefore, an exemption from the requirement of a tolerance is
established in 40 CFR 180.930 for residues of iron oxide
(Fe<INF>3</INF>O<INF>4</INF>) (CAS Reg. No. 1317-61-9) when used as an
inert ingredient (colorant) in pesticide formulations at no more than
0.2% by weight of the final formulation applied to animals.
VII. Statutory and Executive Order Reviews
This action establishes 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 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 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).
