II. Petition for Exemption

    In the Federal Register of August 5, 2009 (74 FR 38935) (FRL-8430-
1), EPA issued a final rule, announcing the establishment of a 
tolerance exemption pursuant to a pesticide petition (PP 9E7534) by The 
Joint Inerts Task Force, Cluster Support Team 1 (CST 1), c/o CropLife 
America, 1156 15th Street NW, Suite 400, Washington, DC 20005. The 
petition requested that 40 CFR 180.910, 180.930, 180.940(a), and 
180.960 be amended by establishing an exemption from the requirement of 
a tolerance for residues of a group of substances known as [alpha]-
alkyl-[omega]-hydroxypoly(oxypropylene) and/or poly (oxyethylene) 
polymers where the alkyl chain contains a minimum of 6 carbons, herein 
referred to in this document as AAA.
    The current petition seeks to expand the exemptions for AAA by 
adding additional CAS Reg. Nos. In the Federal Register of March 22, 
2021 (86 FR 15162) (FRL-10021-44), EPA issued a document pursuant to 
FFDCA section 408, 21 U.S.C. 346a, announcing the filing of a pesticide 
petition (PP IN-11422) by Spring Regulatory Sciences, on behalf of 
Sasol Chemicals (USA) LLC, 12120 Wickchester Ln., Houston, Texas 77224. 
The petition requested that 40 CFR 180.910, 180.930, 180.940(a), and 
180.960 be amended by

[[Page 48033]]

establishing exemptions from the requirement of a tolerance for 
alcohols, C20-30, ethoxylated (CAS Reg. No. 68439-48-5); alcohols, C16-
18, distn. residues, ethoxylated, propoxylated (CAS Reg. No. 2409830-
33-5); alcohol, C22, ethoxylated (CAS Reg. No. 26636-40-8); poly(oxy-
1,2-ethanediyl), [alpha]-(2-butyloctyl)-[omega]-hydroxy- (CAS Reg. No. 
60636-37-5); 2-octyldodecan-1-ol, ethoxylated (CAS Reg. No. 32128-65-
7); and alcohols, C16-20, branched, ethoxylated (CAS Reg. No. 161133-
70-6). That document referenced a summary of the petition prepared by 
Spring Regulatory Sciences on behalf of Sasol Chemicals (USA) LLC, the 
petitioner, which is available in the docket, http://www.regulations.gov.
    There were no comments received in response to the notice of 
filing.
    Based upon review of the data supporting the petition, EPA 
determined that CAS Reg. No. 68439-48-5 currently has exemptions from 
the requirement of a tolerance under the current AAA descriptor in 40 
CFR 180.910, 180.930, 180.940(a), and 180.960. EPA has confirmed that 
the other petitioned CAS Reg. Nos. are acceptable for consideration 
under the current AAA descriptor. This determination is based on the 
Agency's risk assessments, which can be found at http://www.regulations.gov in documents ``Alkyl Alcohol Alkoxylates (AAA-JITF 
CST 1 Inert Ingredient), Human Health Risk Assessment to Support 
Proposed Exemption from the Requirement of a Tolerance when used as an 
Inert Ingredient in Pesticide Formulations'' and ``Alkyl Alcohol 
Alkoxylates (AAA-JITF CST 1 Inert Ingredient), Human Health Risk 
Assessment to Support Proposed Exemption from the Requirement of a 
Tolerance Under 40 CFR 180.960 When Used as an Inert Ingredient in 
Pesticide Formulations'' in docket ID number EPA-HQ-OPP-2009-0145.

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. 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 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 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 to alcohols, C16-18, distn. 
residues, ethoxylated, propoxylated; alcohol, C22, ethoxylated; 
poly(oxy-1,2-ethanediyl), [alpha]- (2-butyloctyl)-[omega]-hydroxy-; 2-
octyldodecan-1-ol, ethoxylated; and alcohols, C16-20, branched, 
ethoxylated, including exposure resulting from the exemptions 
established by this action. EPA's assessment of exposures and risks 
associated with the group of substances known as AAA follows.
    In an effort to streamline its publications in the Federal 
Register, EPA is not reprinting sections that repeat what has been 
previously published for tolerance rulemakings of the same pesticide 
chemical. Where scientific information concerning a particular chemical 
remains unchanged, the content of those sections would not vary between 
tolerance rulemakings, and EPA considers referral back to those 
sections as sufficient to provide an explanation of the information EPA 
considered in making its safety determination for the new rulemaking.
    EPA has previously published tolerance rulemakings for AAA, in 
which EPA concluded, based on the available information, that there is 
a reasonable certainty that no harm would result from aggregate 
exposure to AAA and established exemptions from the requirement of a 
tolerance for residues of those chemicals. EPA is incorporating 
previously published sections from those rulemakings as described 
further in this rulemaking, as they remain unchanged.
    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 AAA 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 Unit IV.A. of the previous AAA tolerance rulemaking 
published in the Federal Register of August 5, 2009 (74 FR 38935) (FRL-
8430-1).
    Toxicological Points of Departure/Levels of Concern. For a summary 
of the Toxicological Points of Departure/Levels of Concern used for the 
safety assessment, see Unit IV.B. of the August 5, 2009 rulemaking.
    Exposure Assessment. The exposure assessment associated with the 
2009 rulemaking for the AAA descriptor included the potential use of 
all chemicals in this category and therefore no additional exposure is 
expected from

[[Page 48034]]

the exemptions established by this action. For a description of the 
Agency's approach to and assumptions for the exposure assessments, see 
Unit IV.C. of the August 5, 2009 rulemaking.
    Safety Factor for Infants and Children. EPA continues to conclude 
that there is reliable data to support the reduction of the Food 
Quality Protection Act (FQPA) safety factor for infants and children 
from 10X to 1X. See Unit IV.D. of the August 5, 2009 rulemaking for a 
discussion of the Agency's rationale for that determination.
    Aggregate Risks and Determination of Safety. EPA determines whether 
acute and chronic dietary pesticide exposures are safe by comparing 
dietary exposure estimates to the acute population adjusted dose (aPAD) 
and the chronic population adjusted dose (cPAD). Short-, intermediate-, 
and chronic-term risks are evaluated by comparing the estimated 
aggregate food, water, and residential exposure to the appropriate 
points of departure to ensure that an adequate margin of exposure (MOE) 
exists. For linear cancer risks, EPA calculates the lifetime 
probability of acquiring cancer given the estimated aggregate exposure.
    An acute dietary exposure assessment was not conducted as 
toxicological effects attributable to a single dose were not 
identified. Chronic dietary risks are below the Agency's level of 
concern of 100% of the cPAD with a value of 37% of the cPAD for 
children 1 to 2 years old, the population subgroup with the highest 
exposure estimate. EPA concluded that the short- and intermediate-term 
aggregated food, water, and residential exposures both resulted in an 
aggregate MOEs of 110 for children. As the level of concern is for MOEs 
that are lower than 100, these MOEs are not of concern. The AAAs are 
not expected to be carcinogenic as described in Unit IV.C. of the 
August 5, 2009 rulemaking. Therefore, a cancer dietary exposure 
assessment is not necessary to assess cancer risk.
    Based on the risk assessment and information described above, EPA 
concludes there is a reasonable certainty that no harm will result to 
the general population, or to infants and children, from aggregate 
exposure to AAA residues, including residues of alcohols, C16-18, 
distn. residues, ethoxylated, propoxylated (CAS Reg. No. 2409830-33-5); 
alcohol, C22, ethoxylated (CAS Reg. No. 26636-40-8); poly(oxy-1,2-
ethanediyl), [alpha]-(2-butyloctyl)-[omega]-hydroxy- (CAS Reg. No. 
60636-37-5); 2-octyldodecan-1-ol, ethoxylated (CAS Reg. No. 32128-65-
7); and alcohols, C16-20, branched, ethoxylated (CAS Reg. No. 161133-
70-6). More detailed information about the Agency's analysis can be 
found at http://www.regulations.gov in the documents titled ``Alkyl 
Alcohol Alkoxylates (AAA--JITF CST 1 Inert Ingredient), Human Health 
Risk Assessment to Support Proposed Exemption from the Requirement of a 
Tolerance When Used as an Inert Ingredient in Pesticide Formulations'' 
and ``Alkyl Alcohol Alkoxylates (AAA-JITF CST 1 Inert Ingredient), 
Human Health Risk Assessment to Support Proposed Exemption from the 
Requirement of a Tolerance Under 40 CFR 180.960 When Used as an Inert 
Ingredient in Pesticide Formulations'' in docket ID number EPA-HQ-OPP-
2009-0145.

V. Analytical Enforcement Methodology

    An analytical method is not required for enforcement purposes since 
the Agency is establishing exemptions from the requirement of a 
tolerance without any numerical limitation.

VI. Conclusions

    Therefore, exemptions from the requirement of a tolerance are 
established for residues of the following [alpha]-alkyl-[omega]-
hydroxypoly(oxypropylene) and/or poly (oxyethylene) polymers where the 
alkyl chain contains a minimum of 6 carbons: alcohols, C16-18, distn. 
residues, ethoxylated, propoxylated (CAS Reg. No. 2409830-33-5); 
alcohol, C22, ethoxylated (CAS Reg. No. 26636-40-8); poly(oxy-1,2-
ethanediyl), [alpha]-(2-butyloctyl)-[omega]-hydroxy- (CAS Reg. No. 
60636-37-5); 2-octyldodecan-1-ol, ethoxylated (CAS Reg. No. 32128-65-
7); and alcohols, C16-20, branched, ethoxylated (CAS Reg. No. 161133-
70-6) when used as inert ingredients in pesticide formulations pre- and 
post-harvest under 40 CFR 180.910, applied to animals under 40 CFR 
180.930, and in antimicrobial formulations applied to food-contact 
surfaces in public eating places, dairy-processing equipment, and food-
processing equipment and utensils under 40 CFR 180.940(a). 
Additionally, exemptions from the requirement of a tolerance are 
established under 40 CFR 180.960 for residues of these substances with 
a minimum number average molecular weight (in amu) of 1,100 when used 
as an inert ingredient in pesticide formulations, including 
antimicrobial formulations.

VII. Statutory and Executive Order Reviews

    This action establishes 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). 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 exemptions 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

[[Page 48035]]

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).
