Oxirane, 2-methyl, Polymer With Oxirane, Hydrogen Sulfate, 
Ammonium Salt and Potassium Salt; 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, 
hydrogen sulfate, ammonium salt and oxirane, 2-methyl, polymer with 
oxirane, hydrogen sulfate, potassium salt; when used as an inert 
ingredient in a pesticide chemical formulation. Clariant Corporation, 
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, hydrogen sulfate, ammonium salt and oxirane, 2-methyl, polymer 
with oxirane, hydrogen sulfate, potassium salt on food or feed 
commodities.

DATES: This regulation is effective July 5, 2017. Objections and 
requests for hearings must be received on or before September 5, 2017,

II. Background and Statutory Findings

    In the Federal Register of April 10, 2017 (82 FR 17175) (FRL-9959-
61), EPA issued a document pursuant to FFDCA section 408, 21 U.S.C. 
346a, announcing the receipt of a pesticide petition (PP IN-11004) 
filed by Clariant Corporation, 4000 Monroe Road, Charlotte NC 28205. 
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, hydrogen sulfate, ammonium 
salt and oxirane, 2-methyl, polymer with oxirane, hydrogen sulfate, 
potassium salt; CAS Nos. 57608-14-7 and 1838191-48-2, respectively. 
That document 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 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, hydrogen sulfate, ammonium salt and potassium salt 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 polymers are not a cationic polymer nor is it reasonably 
anticipated to become a cationic polymer in a natural aquatic 
environment.
    2. The polymers do contain as an integral part of its composition 
the atomic elements carbon, hydrogen, and oxygen.
    3. The polymers do not contain as an integral part of their 
composition, except as impurities, any element other than those listed 
in 40 CFR 723.250(d)(2)(ii).
    4. The polymers are neither designed nor can it be reasonably 
anticipated to substantially degrade, decompose, or depolymerize.
    5. The polymers are 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 polymers are not a water absorbing polymer with a number 
average molecular weight (MW) greater than or equal to 10,000 daltons.
    7. The polymers do not contain certain perfluoroalkyl moieties 
consisting of a CF3- or longer chain length as specified in 40 CFR 
723.250(d)(6).
    Additionally, the polymers also meet as required the following 
exemption criteria specified in 40 CFR 723.250(e).
    8. The polymers', oxirane, 2-methyl, polymer with oxirane, hydrogen 
sulfate, ammonium salt and potassium salt, number average MW of 1800 
and 2100, respectively, are greater than 1,000 and less than 10,000 
daltons. The polymers contain less than 10% oligomeric material below 
MW 500 and less than 25% oligomeric material below MW 1,000, and the 
polymers do not contain any reactive functional groups.
    Thus, oxirane, 2-methyl, polymer with oxirane, hydrogen sulfate, 
ammonium salt and potassium salt meet 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, hydrogen sulfate, ammonium salt and potassium salt.

IV. Aggregate Exposures

    For the purposes of assessing potential exposure under this 
exemption, EPA considered that oxirane, 2-methyl, polymer with oxirane, 
hydrogen sulfate, ammonium salt and potassium salt 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, hydrogen 
sulfate, ammonium salt and potassium salt are 1800 and 2100 daltons, 
respectively. Generally, a polymer of this size would

[[Page 30992]]

be poorly absorbed through the intact gastrointestinal tract or through 
intact human skin. Since oxirane, 2-methyl, polymer with oxirane, 
hydrogen sulfate, ammonium salt and potassium salt conform 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 tolerances are 
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, hydrogen 
sulfate, ammonium salt and potassium salt to share a common mechanism 
of toxicity with any other substances, and oxirane, 2-methyl, polymer 
with oxirane, hydrogen sulfate, ammonium salt and potassium salt do 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, hydrogen sulfate, ammonium 
salt and potassium salt do 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 Web site 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, hydrogen sulfate, ammonium salt and potassium 
salt, 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, hydrogen sulfate, ammonium salt and potassium salt.

VIII. Other Considerations

A. Existing Exemptions From a Tolerance

    There are no existing tolerances for oxirane, 2-methyl, polymer 
with oxirane, hydrogen sulfate, ammonium salt and potassium salt.

B. 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.

C. International Residue Limits

    In making its tolerance decisions, EPA seeks to harmonize U.S. 
tolerances with international standards whenever possible, consistent 
with U.S. food safety standards and agricultural practices. EPA 
considers the international maximum residue limits (MRLs) established 
by the Codex Alimentarius Commission (Codex), as required by FFDCA 
section 408(b)(4). The Codex Alimentarius is a joint United Nations 
Food and Agriculture Organization/World Health Organization food 
standards program, and it is recognized as an international food safety 
standards-setting organization in trade agreements to which the United 
States is a party. EPA may establish a tolerance that is different from 
a Codex MRL; however, FFDCA section 408(b)(4) requires that EPA explain 
the reasons for departing from the Codex level.
    The Codex has not established a MRL for oxirane, 2-methyl, polymer 
with oxirane, hydrogen sulfate, ammonium salt and potassium salt.

IX. Conclusion

    Accordingly, EPA finds that exempting residues of oxirane, 2-
methyl, polymer with oxirane, hydrogen sulfate, ammonium salt and 
potassium salt from the requirement of a tolerance will be safe.

X. Statutory and Executive Order Reviews

    This action establishes 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 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

[[Page 30993]]

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).
