Styrene- Maleic Anhydride Ethyl Amine Salt Copolymer; 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 styrene- maleic anhydride ethyl amine 
salt copolymer when used as an inert ingredient in a pesticide chemical 
formulation. S.A. Ajinomoto Omnichem N.V., 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 styrene- maleic anhydride ethyl amine salt copolymer on 
food or feed commodities when used in accordance with these exemptions.

DATES: This regulation is effective September 21, 2021. Objections and 
requests for hearings must be received on or before November 22, 2021, 
and must be filed in accordance with the instructions provided in 40 
CFR part 178 (see also Unit I.C. of the SUPPLEMENTARY INFORMATION).

II. Background and Statutory Findings

    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 receipt of a pesticide petition (PP IN-11408) by 
Wagner Regulatory Associates, Inc., on behalf of, S.A. Ajinomoto 
Omnichem N.V., Cooppallaan, 91 B-9230, Wetteren, Belgium. The petition 
requested that 40

[[Page 52417]]

CFR 180.960 be amended by establishing an exemption from the 
requirement of a tolerance for residues of styrene- maleic anhydride 
ethyl amine salt copolymer. 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 in 
response to the notice of filing.
    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). Styrene- maleic anhydride ethyl amine 
salt copolymer 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.
    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.
    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).
    8. The polymer's number average MW of 1,700 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.
    Thus, styrene- maleic anhydride ethyl amine salt copolymer 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 styrene- maleic anhydride ethyl amine salt copolymer.

IV. Aggregate Exposures

    For the purposes of assessing potential exposure under this 
exemption, EPA considered that styrene- maleic anhydride ethyl amine 
salt copolymer 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 styrene- maleic 
anhydride ethyl amine salt copolymer is 1,700 daltons. Generally, a 
polymer of this size would be poorly absorbed through the intact 
gastrointestinal tract or through intact human skin. Since styrene- 
maleic anhydride ethyl amine salt copolymer 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 styrene- maleic anhydride ethyl amine salt 
copolymer to share a common mechanism of toxicity with any other 
substances, and styrene- maleic anhydride ethyl amine salt copolymer 
does not appear to produce a toxic metabolite produced by other 
substances. For the purposes of this tolerance action, therefore, EPA 
has assumed that styrene- maleic anhydride ethyl amine salt copolymer 
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

[[Page 52418]]

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 styrene- maleic anhydride ethyl amine salt 
copolymer, 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 styrene- maleic anhydride ethyl amine 
salt copolymer.

VIII. 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 styrene- maleic 
anhydride ethyl amine salt copolymer 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 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).
