40 CFR Part 180

[EPA-HQ-OPP-2012-0456; FRL-9367-2]

Styrene-2-Ethylhexyl Acrylate Copolymer; 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 2-propenoic acid, 2-ethylhexyl ester, 
polymer with ethenylbenzene; also known as styrene-2-ethylhexyl 
acrylate copolymer when used as an inert ingredient in a pesticide 
chemical formulation. H. B. Fuller Company 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 2-propenoic acid, 2-Ethylhexyl Ester, Polymer with 
Ethenylbenzene on food or feed commodities.

DATES: This regulation is effective January 30, 2013. Objections and 
requests for hearings must be received on or before April 1, 2013, 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 August 22, 2012 (77 FR 50661) (FRL-9358-
9), EPA issued a document pursuant to FFDCA section 408, 21 U.S.C. 
346a, announcing the receipt of a pesticide petition (PP 2E8033) filed 
by H.B. Fuller Company (1200 Willow Lake Boulevard, St. Paul, MN 55110-
5101). The petition requested that 40 CFR 180.960 be amended by 
establishing an exemption

[[Page 6214]]

from the requirement of a tolerance for residues of 2-propenoic acid, 
2-ethylhexyl ester, polymer with ethenylbenzene; CAS No. 25153-46-2. 
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). Styrene-2-ethylhexyl acrylate 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 
    1. The polymer is not a cationic polymer nor is it reasonably 
anticipated to become a cationic polymer in a natural aquatic 
    2. The polymer does contain as an integral part of its composition 
the atomic elements carbon, hydrogen, and oxygen.
    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.
    Additionally, the polymer also meets as required the following 
exemption criteria specified in 40 CFR 723.250(e).
    7. The polymer's number average MW of 14,000 daltons is greater 
than or equal to 10,000 daltons. The polymer contains less than 2% 
oligomeric material below MW 500 and less than 5% oligomeric material 
below MW 1,000.
    Thus, styrene-2-ethylhexyl acrylate 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-2-
ethylhexyl acrylate copolymer.

IV. Aggregate Exposures

    For the purposes of assessing potential exposure under this 
exemption, EPA considered that styrene-2-ethylhexyl acrylate 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-2-ethylhexyl acrylate 
copolymer is 14,000 daltons. Generally, a polymer of this size would be 
poorly absorbed through the intact gastrointestinal tract or through 
intact human skin. Since styrene-2-ethylhexyl acrylate 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 

    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-2-ethylhexyl acrylate copolymer to share 
a common mechanism of toxicity with any other substances, and styrene-
2-ethylhexyl acrylate 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-2-ethylhexyl 
acrylate 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 Web site at  http://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 styrene-2-ethylhexyl 

[[Page 6215]]

copolymer, EPA has not used a safety factor analysis to assess the 
risk. For the same reasons the additional tenfold safety factor is 

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-2-ethylhexyl acrylate 

VIII. Other Considerations

A. Existing Exemptions From a Tolerance

    There are no existing exemptions from the requirements of a 

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 styrene-2-ethylhexyl 
acrylate copolymer.

IX. Conclusion

    Accordingly, EPA finds that exempting residues of styrene-2-
ethylhexyl acrylate copolymer from the requirement of a tolerance will 
be safe.

X. Statutory and Executive Order Reviews

    This final rule 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 rules from review under 
Executive Order 12866, entitled ``Regulatory Planning and Review'' (58 
FR 51735, October 4, 1993). Because this final rule has been exempted 
from review under Executive Order 12866, this final rule 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 final rule 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 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 of 1995 (NTTAA) (15 U.S.C. 272 
    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 final rule 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, or otherwise have any unique 
impacts on local governments. 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 final rule. In addition, this final rule 
does not impose any enforceable duty or contain any unfunded mandate as 
described under Title II of the Unfunded Mandates Reform Act of 1995 
(UMRA) (2 U.S.C. 1501 et seq.).
    Although this action does not 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), EPA seeks to achieve 
environmental justice, the fair treatment and meaningful involvement of 
any group, including minority and/or low-income populations, in the 
development, implementation, and enforcement of environmental laws, 
regulations, and policies. As such, to the extent that information is 
publicly available or was submitted in comments to EPA, the Agency 
considered whether groups or segments of the population, as a result of 
their location, cultural practices, or other factors, may have atypical 
or disproportionately high and adverse human health impacts or 
environmental effects from exposure to the pesticide discussed in this 
document, compared to the general population.

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).
