Acetophenone; 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 acetophenone when used as an inert 
ingredient (solvent or co-solvent) in pesticide formulations applied to 
growing crops. ADAMA Makhteshim Ltd. submitted a petition to EPA under 
the Federal Food, Drug, and Cosmetic Act (FFDCA), requesting the 
establishment of this exemption from the requirement of a tolerance. 
This regulation eliminates the need to establish a maximum permissible 
level for residues of acetophenone, when used in accordance with the 
terms of that exemption.

DATES: This regulation is effective April 10, 2023. Objections and 
requests for hearings must be received on or before June 9, 2023, and 
must be filed in accordance with the instructions provided in 40 CFR 
part 178 (see also Unit I.C. of the SUPPLEMENTARY INFORMATION).

    In the Federal Register of June 1, 2021 (86 FR 29229) (FRL-10023-
95), EPA issued a document pursuant to FFDCA section 408, 21 U.S.C. 
346a, announcing the filing of a pesticide petition (PP IN-11493) by 
ADAMA Makhteshim Ltd., 3120 Highwoods Blvd., Suite 100, Raleigh, NC 
27604. The petition requested that the existing exemption in 40 CFR 
180.920 for residues of acetophenone (CAS Reg. No. 98-86-2) be amended 
to include additional uses for acetophenone as a solvent or co-solvent 
inert ingredient in pesticide formulations applied to growing crops. 
That document referenced a summary of the petition prepared by ADAMA 
Makhteshim Ltd., the petitioner, which is available in the docket, 
https://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 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 acetophenone including exposure 
resulting from the exemption established by this action. EPA's 
assessment of exposures and risks associated with acetophenone 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 acetophenone as well as the no-
observed-adverse-effect-level (NOAEL)

[[Page 21105]]

and the lowest-observed-adverse-effect-level (LOAEL) from the toxicity 
studies are discussed in this unit.
    Available acute studies on acetophenone show moderate oral and low 
dermal toxicity. An inhalation toxicity study showed moderate 
inhalation toxicity. Acetophenone was shown to be a mild irritant to 
the skin and a severe eye irritant but was not reported to be a dermal 
sensitizer.
    Several repeat dose oral studies (i.e., a 17-week dietary toxicity 
study in rats, a 90-day gavage study in rats, two developmental 
toxicity studies in rats and rabbits and a repeat dose toxicity test 
combined with a reproductive/developmental screening test in rats) have 
been conducted with acetophenone. The most sensitive effect in the 
acetophenone database is decreased body weight, which was observed 
starting at 300 mg/kg/day in a developmental gavage study in rats and 
at 500 mg/kg/day in the 90-day gavage study in rats.

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 https://www.epa.gov/pesticide-science-and-assessing-pesticide-risks/overview-risk-assessment-pesticide-program.
    No effects attributed to a single exposure were seen in the studies 
provided and therefore, a point of departure (POD) for acute dietary 
risk was not determined. The most sensitive effect in the acetophenone 
database is decreased body weight, which was observed starting at 300 
mg/kg/day in a developmental gavage study in rats and at 500 mg/kg/day 
in the 90-day gavage study in rats. Therefore, both studies are 
considered co-critical. The chronic dietary, incidental oral, dermal 
and inhalation endpoints are selected from the NOAEL of 250 mg/kg/day 
based on body weight changes observed starting at 300 mg/kg/day in 
rats.

C. Exposure Assessment

    1. Dietary exposure from food and feed uses. In evaluating dietary 
exposure to acetophenone, EPA considered exposure under the proposed 
exemption from the requirement of a tolerance. EPA assessed dietary 
exposures from acetophenone in food as follows:
    Because no acute endpoint of concern was identified, a quantitative 
acute dietary exposure assessment is unnecessary. In conducting the 
chronic dietary exposure assessment using the Dietary Exposure 
Evaluation Model DEEM-FCID\TM\, Version 4.02, EPA used food consumption 
information from the U.S. Department of Agriculture's National Health 
and Nutrition Examination Survey, What we eat in America, (NHANES/
WWEIA). This dietary survey was conducted from 2005 to 2010. The Inert 
Dietary Exposure Evaluation Model (I-DEEM) is a highly conservative 
model with the assumption that the residue level of the inert 
ingredient would be no higher than the highest tolerance for a given 
commodity. Implicit in this assumption is that there would be similar 
rates of degradation between the active and inert ingredient (if any) 
and that the concentration of inert ingredient in the scenarios leading 
to these highest of tolerances would be no higher than the 
concentration of the active ingredient. The model assumes 100 percent 
crop treated (PCT) for all crops and that every food eaten by a person 
each day has tolerance-level residues. A complete description of the 
general approach taken to assess inert ingredient risks in the absence 
of residue data is contained in the memorandum entitled ``Update to 
D361707: Dietary Exposure and Risk Assessments for the Inerts.'' (12/
21/2021) and can be found at https://www.regulations.gov in docket ID 
number EPA-HQ-OPP-2018-0090-0002.
    2. Dietary exposure from drinking water. For the purpose of the 
screening level dietary risk assessment to support this request for an 
exemption from the requirement of a tolerance for acetophenone, a 
conservative drinking water concentration value of 100 ppb based on 
screening level modeling was used to assess the contribution to 
drinking water for the chronic dietary risk assessments for parent 
compound. These values were directly entered into the dietary exposure 
model.
    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). Based 
on the pesticide product labels reviewed, in a conservative effort to 
assess exposure, the EPA has conducted a screening level assessment 
using high-end exposure scenarios for pesticidal use on lawns/turf and 
antimicrobial cleaning products.
    Risks were calculated using the Margin of Exposure (MOE) approach. 
This is a ratio of the body burden to the toxicological Point of 
Departure (POD). A MOE greater than 100 indicates that the exposure 
scenario does not demonstrate a risk of concern for acetophenone. For 
all residential handler and post-application scenarios, for both adults 
and children, for application of pesticides containing this inert 
ingredient to lawns and turf and use in cleaning produces, the MOEs 
were greater than 100 and therefore, there is no risk of concern.
    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.''
    EPA has not found acetophenone to share a common mechanism of 
toxicity with any other substances, and acetophenone does not appear to 
produce a toxic metabolite produced by other substances. For the 
purposes of this tolerance action, therefore, EPA has assumed that 
acetophenone 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.

[[Page 21106]]

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 (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.
    2. Prenatal and postnatal sensitivity. No evidence of offspring 
susceptibility was observed in the available developmental studies in 
rats and rabbits or the reproductive/developmental toxicity study in 
rats. The offspring effects observed in all three studies occurred only 
in the presence of maternal toxicity.
    3. Conclusion. EPA has determined that reliable data show the 
safety of infants and children would be adequately protected if the 
FQPA SF were reduced from 10X to 1X. That decision is based on the 
following findings:
    i. The toxicity database for acetophenone is complete.
    ii. Acetophenone is a known hypnotic. Clinical signs of 
neurotoxicity were observed in the available studies. However, these 
effects were seen at the same or higher doses than the body weight 
changes. Therefore, the POD is protective of any potential 
neurotoxicity effects.
    iii. There is no evidence that acetophenone results in increased 
susceptibility in in utero rats or rabbits in the prenatal 
developmental studies or in young rats in the 2-generation reproduction 
study.
    iv. There are no residual uncertainties identified in the exposure 
databases. The dietary food exposure assessments were performed based 
on 100% CT and tolerance-level residues. EPA made conservative 
(protective) assumptions in the ground and surface water modeling used 
to assess exposure to acetophenone in drinking water. EPA used 
similarly conservative assumptions to assess post-application exposure 
of children as well as incidental oral exposure of toddlers. These 
assessments will not underestimate the exposure and risks posed by 
acetophenone.

E. Aggregate Risks and Determination of Safety

    EPA determines whether acute and chronic dietary pesticide 
exposures are safe by comparing aggregate exposure estimates to the 
acute PAD (aPAD) and chronic PAD (cPAD). For linear cancer risks, EPA 
calculates the lifetime probability of acquiring cancer given the 
estimated aggregate exposure. Short-, intermediate-, and chronic-term 
risks are evaluated by comparing the estimated aggregate food, water, 
and residential exposure to the appropriate PODs to ensure that an 
adequate MOE exists.
    1. Acute risk. An acute aggregate risk assessment takes into 
account acute exposure estimates from dietary consumption of food and 
drinking water. No adverse effect resulting from a single oral exposure 
was identified and no acute dietary endpoint was selected. Therefore, 
acetophenone is not expected to pose an acute risk.
    2. Chronic risk. Using the exposure assumptions described in this 
unit for chronic exposure, EPA has concluded that chronic exposure to 
acetophenone from food and water will utilize 41.2% of the cPAD for 
children 1 to 2 years old, the population group receiving the greatest 
exposure. Based on the explanation in this unit, regarding residential 
use patterns, chronic residential exposure to residues of acetophenone 
is not expected.
    3. Short-term risk. Short-term aggregate exposure takes into 
account short-term residential exposure plus chronic exposure to food 
and water (considered to be a background exposure level). Acetophenone 
is currently used as an inert ingredient in pesticide products that are 
registered for uses that could result in short-term residential 
exposure, and the Agency has determined that it is appropriate to 
aggregate chronic exposure through food and water with short-term 
residential exposures to acetophenone.
    Using the exposure assumptions described in this unit for short-
term exposures, EPA has concluded the combined short-term food, water, 
and residential exposures result in aggregate MOEs of 120 for adults 
and 110 for children 1 to 2 years old. These MOEs are not of concern 
because EPA's level of concern for acetophenone is a MOE of 100 or 
below.
    4. Intermediate-term risk. Intermediate-term aggregate exposure 
takes into account intermediate-term residential exposure plus chronic 
exposure to food and water (considered to be a background exposure 
level). An intermediate-term adverse effect was identified; however, 
acetophenone is not currently used as an inert ingredient in pesticide 
products that are registered for any use patterns that would result in 
intermediate-term residential exposure. Intermediate-term risk is 
assessed based on intermediate-term residential exposure plus chronic 
dietary exposure. Because there is no intermediate-term residential 
exposure and chronic dietary exposure has already been assessed under 
the appropriately protective cPAD (which is at least as protective as 
the POD used to assess intermediate-term risk), no further assessment 
of intermediate-term risk is necessary, and EPA relies on the chronic 
dietary risk assessment for evaluating intermediate-term risk for 
acetophenone.
    5. Aggregate cancer risk for U.S. population. Based on the lack of 
structural alerts for carcinogenicity coupled with the result from the 
studies indicating low concern for mutagenicity, there is low concern 
for carcinogenicity with acetophenone. Therefore, acetophenone is not 
expected to pose a cancer risk to humans.
    6. Determination of safety. Based on these risk assessments, 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 acetophenone 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, an exemption from the requirement of a tolerance 
established under 40 CFR 180.920 for acetophenone (CAS Reg. No. 98-86-
2) can be amended to include the use as an inert ingredient (solvent or 
co-solvent) in pesticide formulations applied pre-harvest to growing 
crops only.

VII. Statutory and Executive Order Reviews

    This action establishes an exemption from the tolerance requirement 
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

[[Page 21107]]

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 tolerance 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).
