40 CFR Part 180

[EPA-HQ-OPP-2022-0325; FRL-9983-01-OCSPP]


IN-11693: Oxirane, 2-Methyl-, Polymer With Oxirane, di-(9Z)-9-
Octadecenoate; Tolerance Exemption

AGENCY: Environmental Protection Agency (EPA).

ACTION: Final rule.

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

SUMMARY: This regulation establishes an exemption from the requirement 
of a tolerance for residues of oxirane, 2-methyl-, polymer with 
oxirane, di-(9Z)-9-octadecenoate (CAS Reg. No. 67167-17-3) average 
number molecular weight (in amu), 2500 when used as an inert ingredient 
in a pesticide chemical formulation. Ethox Chemicals, LLC, submitted a 
petition to EPA under the Federal Food, Drug, and Cosmetic Act (FFDCA), 
requesting an exemption from the requirement of a tolerance. This 
regulation eliminates the need to establish a maximum permissible level 
for residues of oxirane, 2-methyl-, polymer with oxirane, di-(9Z)-9-
octadecenoate on food or feed commodities.

II. Background and Statutory Findings

    In the Federal Register of May 20, 2022 (87 FR 30855) (FRL-9410-
13), EPA issued a notice pursuant to section 408 of FFDCA, 21 U.S.C. 
346a, announcing the receipt of a pesticide petition (PP IN-11693) 
filed by Ethox Chemicals, LLC (1801 Perimeter Road, Greenville, SC 
29605). The petition requested that 40 CFR 180.960 be amended by 
establishing an exemption from the requirement of a tolerance for 
residues of oxirane, 2-methyl-, polymer with oxirane, di-(9Z)-9-
octadecenoate (CAS Reg. No. 67167-17-3). That notice included a summary 
of the petition prepared by the petitioner and solicited comments on 
the petitioner's request. The Agency did not receive any comments.
    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 use 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 an exemption from the 
requirement of 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 . . .'' and 
specifies factors EPA is to consider in establishing an exemption.

III. Risk Assessment and Statutory Findings

    EPA establishes exemptions from the requirement of a tolerance only 
in those cases where it can be shown 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(b)(2)(D), EPA has reviewed the 
available scientific data and other relevant information in support of 
this action and considered its validity, completeness and reliability 
and the

[[Page 47636]]

relationship of this information 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. In the case of certain chemical substances that are defined 
as polymers, the Agency has established a set of criteria to identify 
categories of polymers expected to present minimal or no risk. The 
definition of a polymer is given in 40 CFR 723.250(b) and the exclusion 
criteria for identifying these low-risk polymers are described in 40 
CFR 723.250(d). Oxirane, 2-methyl-, polymer with oxirane, di-(9Z)-9-
octadecenoate conforms to the definition of a polymer given in 40 CFR 
723.250(b) and meets the following criteria that are used to identify 
low-risk polymers.
    1. The polymer is not a cationic polymer nor is it reasonably 
anticipated to become a cationic polymer in a natural aquatic 
environment.
    2. The polymer does contain as an integral part of its composition 
at least two of the atomic elements carbon, hydrogen, nitrogen, oxygen, 
silicon, and sulfur.
    3. The polymer does not contain as an integral part of its 
composition, except as impurities, any element other than those listed 
in 40 CFR 723.250(d)(2)(ii).
    4. The polymer is neither designed nor can it be reasonably 
anticipated to substantially degrade, decompose, or depolymerize. 
Although hydrolysis is expected in the environment to yield oleic acid 
and ethylene oxide/propylene oxide (E.O./PO) copolymer, the E.O./PO 
copolymer portion is not anticipated to further biodegrade.
    5. The polymer is manufactured or imported from monomers and/or 
reactants that are already included on the TSCA Chemical Substance 
Inventory or manufactured under an applicable TSCA section 5 exemption.
    6. The polymer is not a water absorbing polymer with a number 
average molecular weight (MW) greater than or equal to 10,000 daltons. 
Additionally, the polymer also meets as required the following 
exemption criteria specified in 40 CFR 723.250(e).
    7. The polymer does not contain certain perfluoroalkyl moieties 
consisting of a CF3- or longer chain length as listed in 40 
CFR 723.250(d)(6). Additionally, the polymer also meets as required the 
following exemption criteria: specified in 40 CFR 723.250(e):
    The number average molecular weight is greater than 1,000 and less 
than 10,000 Daltons. The polymer contains less than 10% oligomeric 
material below MW 500 and less than 25% oligomeric material below MW 
1,000 and the polymer does not contain any reactive functional groups 
as specified in 40 CFR 723.250.
    Thus, oxirane, 2-methyl-, polymer with oxirane, di-(9Z)-9-
octadecenoate meets the criteria for a polymer to be considered low 
risk under 40 CFR 723.250. Based on its conformance to the criteria in 
this unit, no mammalian toxicity is anticipated from dietary, 
inhalation, or dermal exposure to oxirane, 2-methyl-, polymer with 
oxirane, di-(9Z)-9-octadecenoate.

IV. Aggregate Exposures

    For the purposes of assessing potential exposure under this 
exemption, EPA considered that oxirane, 2-methyl-, polymer with 
oxirane, di-(9Z)-9-octadecenoate could be present in all raw and 
processed agricultural commodities and drinking water, and that non-
occupational non-dietary exposure was possible. The number average MW 
of oxirane, 2-methyl-, polymer with oxirane, di-(9Z)-9-octadecenoate is 
2,500 daltons. Generally, a polymer of this size would be poorly 
absorbed through the intact gastrointestinal tract or through intact 
human skin. Since oxirane, 2-methyl-, polymer with oxirane, di-(9Z)-9-
octadecenoate conforms to the criteria that identify a low-risk 
polymer, there are no concerns for risks associated with any potential 
exposure scenarios that are reasonably foreseeable. The Agency has 
determined that a tolerance is not necessary to protect the public 
health.

V. 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 oxirane, 2-methyl-, polymer with oxirane, di-
(9Z)-9-octadecenoate to share a common mechanism of toxicity with any 
other substances, and oxirane, 2-methyl-, polymer with oxirane, di-
(9Z)-9-octadecenoate does not appear to produce a toxic metabolite 
produced by other substances. For the purposes of this tolerance 
action, therefore, EPA has assumed that oxirane, 2-methyl-, polymer 
with oxirane, di-(9Z)-9-octadecenoate 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/pesticides/cumulative.

VI. 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 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 data base unless EPA concludes 
that a different margin of safety will be safe for infants and 
children. Due to the expected low toxicity of oxirane, 2-methyl-, 
polymer with oxirane, di-(9Z)-9-octadecenoate, EPA has not used a 
safety factor analysis to assess the risk. For the same reasons the 
additional tenfold safety factor is unnecessary.

VII. Determination of Safety

    Based on the conformance to the criteria used to identify a low-
risk polymer, EPA concludes that there is a reasonable certainty of no 
harm to the U.S. population, including infants and children, from 
aggregate exposure to residues of oxirane, 2-methyl-, polymer with 
oxirane, di-(9Z)-9-octadecenoate.

VIII. Other Considerations

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.

IX. Conclusion

    Accordingly, EPA finds that exempting residues of oxirane, 2-
methyl-, polymer with oxirane, di-(9Z)-9-octadecenoate from the 
requirement of a tolerance will be safe.

X. 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

[[Page 47637]]

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).

XI. 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).
