This regulation amends an exemption from the requirement of a tolerance to allow for residues of 1,1-difluoroethane (CAS Reg. No. 75- 37-6) when used as an inert ingredient (aerosol propellant) in bird repellent pesticide products applied to growing crops and raw agricultural commodities after harvest and to animals. Pyxis Regulatory Consulting, on behalf of Avian Enterprises Limited LLC, submitted a petition to EPA under the Federal Food, Drug, and Cosmetic Act (FFDCA), requesting an amendment to an existing requirement of a tolerance. This regulation eliminates the need to establish a maximum permissible level for residues of 1,1-difluoroethane when used in accordance with the terms of the exemption.

1,1-Difluoroethane; Exemption From the Requirement of a Tolerance

AGENCY: Environmental Protection Agency (EPA).

ACTION: Final rule.

-----------------------------------------------------------------------

SUMMARY: This regulation amends an exemption from the requirement of a 
tolerance to allow for residues of 1,1-difluoroethane (CAS Reg. No. 75-
37-6) when used as an inert ingredient (aerosol propellant) in bird 
repellent pesticide products applied to growing crops and raw 
agricultural commodities after harvest and to animals. Pyxis Regulatory 
Consulting, on behalf of Avian Enterprises Limited LLC, submitted a 
petition to EPA under the Federal Food, Drug, and Cosmetic Act (FFDCA), 
requesting an amendment to an existing requirement of a tolerance. This 
regulation eliminates the need to establish a maximum permissible level 
for residues of 1,1-difluoroethane when used in accordance with the 
terms of the exemption.

II. Petition for Exemption

    In the Federal Register of March 21, 2018 (82 FR 12311) (FRL-9974-
76), EPA issued a document pursuant to FFDCA section 408, 21 U.S.C. 
346a, announcing the filing of a pesticide petition (IN-11082) by Pyxis 
Regulatory Consulting (4110 136TH ST CT NW, Gig Harbor, WA 98332) on 
behalf of Avian Enterprises Limited LLC (2000 Pontiac Drive, Sylvan 
Lake, MI 48320). The petition requested that 40 CFR 180.910 and 40 CFR 
180.930 be amended by modifying the current exemptions from the 
requirement of a tolerance for residues of 1,1-difluoroethane (CAS Reg. 
No. 75-37-6) when used as an inert ingredient (propellant) in pesticide 
formulations applied to growing crops and to raw agricultural 
commodities after harvest and to animals to allow for the additional 
use in bird repellant pesticide formulations applied to growing crops, 
raw agricultural commodities after harvest, and animals. That document 
referenced a summary of the petition prepared by Pyxis Regulatory 
Consulting on behalf of Avian Enterprises Limited LLC, the petitioner, 
which is available in the docket, http://www.regulations.gov. No 
relevant comments were received on 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(b)(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. 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 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 1,1-difluoroethane including 
exposure resulting from the exemption established by this action. EPA's 
assessment of exposures and risks associated with 1,1-difluoroethane 
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 1,1-difluoroethane 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.
    In an acute inhalation toxicity study in rats for 1,1-
difluoroethane, the lethal concentration, LC50 is >475,500 
parts per million (ppm) (oral equivalent approximately 235,399 
milligram/kilogram/day (mg/kg/day)).
    No adverse toxic effects are observed in rats treated via 
inhalation with 1,1-difluoroethane following subchronic exposure up to 
100,000 ppm (oral equivalent approximately 82,600 mg/kg/day), chronic 
exposure up to 25,000 ppm (oral equivalent approximately 20,649 mg/kg/
day) or developmental toxicity studies at doses up to 50,000 ppm (oral 
equivalent approximately 41,300 mg/kg/day), the highest dose tested in 
each exposure scenario.
    Although reproduction toxicity studies are not available with 1,1-
difluoroethane, EPA does not expect 1,1-difluoroethane to cause any 
reproductive toxicity effects. Fetal susceptibility was not observed in 
the developmental toxicity study via inhalation with rats treated with 
1,1-difluoroethane as neither maternal nor developmental toxicity is 
observed up to 50,000 ppm (oral equivalent approximately 41,300 mg/kg/
day), the highest dose tested. Additionally, no signs of systemic 
toxicity or reproduction organ toxicity are observed following 
subchronic and chronic exposures at 100,000 ppm (oral equivalent 
approximately 82,600 mg/kg/day) and 25,000 ppm (oral equivalent 
approximately 20,649 mg/kg/day), the highest doses tested, 
respectively.
    Toxicity is not observed in the carcinogenicity/chronic toxicity 
study via inhalation with rats treated with 1,1-difluoroethane up to 
25,000 ppm (oral equivalent approximately 20,649 mg/kg/day), the 
highest dose tested. Therefore, 1,1-difluoroethane is not expected to 
be carcinogenic.
    Mutagenicity studies are available with 1,1-difluoroethane. The 
bacterial reverse mutation test and the micronucleus test were 
negative. The mammalian chromosomal aberration test in human 
lymphocytes gave a weak positive response and the sex-linked recessive 
lethal test in Drosophila melanogaster gave a positive response.

[[Page 35426]]

Based on the submitted studies the mutagenic potential of 1,1-
difluoroethane is equivocal.
    Neurotoxicity and immunotoxicity studies are not available for 
review. However, evidence of neurotoxicity and immunotoxicity is not 
observed in the submitted studies.
    The metabolism study was conducted with difluoromethane which is 
structurally similar to 1,1-difluoroethane. Difluoromethane differs 
only by a carbon atom and is considered a suitable surrogate chemical 
as it would be expected to be metabolized in a fashion similar to1,1-
difluoroethane. Therefore, data from the metabolism study conducted 
with difluoromethane are used to describe 1,1-difluoroethane 
metabolism. Based on the metabolism study in rats treated with 
difluoromethane, 1,1-difluoroethane is expected to be poorly absorbed 
and rapidly metabolized. Of the absorbed dose, most is expected to be 
metabolized and excreted via exhaled carbon dioxide and organics 
followed by excretion in the urine and feces.

B. Toxicological Points of Departure/Levels of Concern

    The available toxicity studies indicate that 1,1-difluoroethane has 
a very low overall toxicity. The lowest NOAEL in the database was 
25,000 ppm (approximately 20,649 mg/kg/day human equivalent oral dose) 
observed in a chronic/carcinogenicity toxicity study in rats via the 
inhalation route of exposure. Since signs of toxicity were not observed 
at levels well above the limit dose (1,000 mg/kg/day) an endpoint of 
concern for risk assessment purposes was not identified. Therefore, 
since no endpoint of concern was identified for the acute and chronic 
dietary exposure assessment as well as for short- and intermediate-term 
dermal and inhalation exposure, a qualitative risk assessment for 1,1-
difluoroethane was conducted.

C. Exposure Assessment

    1. Dietary exposure from food and feed uses. In evaluating dietary 
exposure to 1,1-difluoroethane, EPA considered exposure under the 
proposed exemptions from the requirement of a tolerance, as well as the 
existing exemptions and from other dietary sources of exposure. EPA 
assessed dietary exposures from 1,1-difluoroethane in food as follows:
    Dietary exposure (food) to 1,1-difluoroethane can occur following 
ingestion of foods with residues from treated crops or animals or from 
the use of 1,1-difluoroethane as an aerosol propellent in consumer 
products used in or on food. However, a dietary exposure assessment was 
not conducted since no endpoint of concern was identified in the 
available database.
    2. Dietary exposure from drinking water. Since a hazard endpoint of 
concern was not identified for the acute and chronic dietary 
assessment, a quantitative dietary exposure risk assessment for 
drinking water was not conducted, although exposures may be expected 
from use on food crops and runoff in the ground water.
    3. 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).
    1,1-Difluoroethane may be used in pesticide products and non-
pesticide products that may be used in and around the home. Based on 
the discussion above, a quantitative residential exposure assessment 
for 1,1-difluoroethane was not conducted.
    4. 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, 1,1-difluoroethane does not have a 
toxic mechanism; therefore, section 408(b)(2)(D)(v) does not apply.

D. Safety Factor for Infants and Children

    1. In general. 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 Safety Factor (FQPA 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.
    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. Based on an 
assessment of 1,1-difluoroethane, 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 the exemptions from the requirement of a tolerance to 
residues of 1,1-difluoroethane are safe, i.e., there is a reasonable 
certainty that no harm will result to the general population, or to 
infants and children, from aggregate exposure to 1,1-difluoroethane 
residues.

V. 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.

VI. Conclusions

    Therefore, the exemptions from the requirement of a tolerance for 
residues of 1,1-difluoroethane (CAS Reg. No. 75-37-6) contained in 40 
CFR 180.910 and 180.930 are amended to add the use of 1,1-
difluoroethane in bird repellent pesticide formulations.

VII. Statutory and Executive Order Reviews

    This action amends exemptions 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), nor is 
it considered a regulatory action subject to 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

[[Page 35427]]

Address Environmental Justice in Minority Populations and Low-Income 
Populations'' (59 FR 7629, February 16, 1994).
    Since tolerances and exemptions that are amended 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 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).
