[EPA-HQ-OPP-2008-0475; FRL-8380-1]

Acetic acid ethenyl ester, polymer with sodium 2-methyl-2-[(1-
oxo-2-propen-1-yl)amino]-1-propanesulfonate (1:1), hydrolyzed;
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 acetic acid ethenyl ester, polymer with
sodium 2-methyl-2-[(1-oxo-2-propen-1-yl)amino]-1-propanesulfonate
(1:1), hydrolyzed (CAS No. 924892-37-5); when used as an inert
ingredient in a pesticide chemical formulation. Celanese Ltd. 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 acetic acid ethenyl ester, polymer with sodium 2-
methyl-2-[(1-oxo-2-propen-1-yl)amino]-1-propanesulfonate (1:1),
hydrolyzed on food or feed commodities.

II. Background and Statutory Findings

    In the Federal Register of July 9, 2008 (73 FR 39289) (FRL-8371-2),
EPA issued a notice pursuant to section 408 of FFDCA, 21 U.S.C. 346a,
announcing the receipt of a pesticide petition (PP 8E7364) filed by
Celanese Ltd., 1601 West LBJ Freeway, Dallas, TX 75234. The petition
requested that 40 CFR 180.960 be amended by establishing an exemption
from the requirement of a tolerance for residues of acetic acid ethenyl
ester, polymer with sodium 2-methyl-2-[(1-oxo-2-propen-1-yl)amino]-1-
propanesulfonate (1:1), hydrolyzed; CAS No. 924892-37-5. 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 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 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 section 408(b)(2)(D) of FFDCA, 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). Acetic acid ethenyl ester, polymer with
sodium 2-methyl-2-[(1-oxo-2-propen-1-yl)amino]-1-propanesulfonate
(1:1), hydrolyzed 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
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 61,000 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, acetic acid ethenyl ester, polymer with sodium 2-methyl-2-
[(1-oxo-2-propen-1-yl)amino]-1-propanesulfonate (1:1), hydrolyzed 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 acetic acid ethenyl ester, polymer with sodium 2-methyl-2-
[(1-oxo-2-propen-1-yl)amino]-1-propanesulfonate (1:1), hydrolyzed.

IV. Aggregate Exposures

    For the purposes of assessing potential exposure under this
exemption, EPA considered that acetic acid ethenyl ester, polymer with
sodium 2-methyl-2-[(1-oxo-2-propen-1-yl)amino]-1-propanesulfonate
(1:1), hydrolyzed 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 acetic acid
ethenyl ester, polymer with sodium 2-methyl-2-[(1-oxo-2-propen-1-
yl)amino]-1-propanesulfonate (1:1), hydrolyzed is 61,000 daltons.
Generally, a polymer of this size would be poorly

[[Page 52618]]

absorbed through the intact gastrointestinal tract or through intact
human skin. Since acetic acid ethenyl ester, polymer with sodium 2-
methyl-2-[(1-oxo-2-propen-1-yl)amino]-1-propanesulfonate (1:1),
hydrolyzed 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 a tolerance is not necessary to protect the public health.

V. Cumulative Effects

    Section 408 (b)(2)(D)(v) of FFDCA requires that, when considering
whether to establish, modify, or revoke a tolerance or tolerance
exemption, the Agency consider ``available information'' concerning the
cumulative effects of a particular chemical's residues and ``other
substances that have a common mechanism of toxicity.'' For the purposes
of this tolerance action, EPA has not assumed that acetic acid ethenyl
ester, polymer with sodium 2-methyl-2-[(1-oxo-2-propen-1-yl)amino]-1-
propanesulfonate (1:1), hydrolyzed has a common mechanism of toxicity
with other substances, based on the anticipated absence of mammalian
toxicity. 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 the policy statements
released by EPA's Office of Pesticide Programs concerning common
mechanism determinations and procedures for cumulating effects from
substances found to have a common mechanism on EPA's website 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 database unless EPA concludes that
a different margin of safety will be safe for infants and children. Due
to the expected low toxicity of acetic acid ethenyl ester, polymer with
sodium 2-methyl-2-[(1-oxo-2-propen-1-yl)amino]-1-propanesulfonate
(1:1), hydrolyzed, 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 acetic acid ethenyl ester, polymer
with sodium 2-methyl-2-[(1-oxo-2-propen-1-yl)amino]-1-propanesulfonate
(1:1), hydrolyzed.

VIII. Other Considerations

A. 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.

B. International Tolerances

    The Agency is not aware of any country requiring a tolerance for
acetic acid ethenyl ester, polymer with sodium 2-methyl-2-[(1-oxo-2-
propen-1-yl)amino]-1-propanesulfonate (1:1), hydrolyzed nor have any
CODEX Maximum Residue Levels (MRLs) been established for any food crops
at this time.

IX. Conclusion

    Accordingly, EPA finds that exempting residues of acetic acid
ethenyl ester, polymer with sodium 2-methyl-2-[(1-oxo-2-propen-1-
yl)amino]-1-propanesulfonate (1:1), hydrolyzed from the requirement of
a tolerance will be safe.

X. Statutory and Executive Order Reviews

    This final rule establishes a tolerance under section 408(d) of
FFDCA 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), Public Law 104-113, section 12(d) (15
U.S.C. 272 note).
    Since tolerances and exemptions that are established on the basis
of a petition under section 408(d) of FFDCA, 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 section 408(n)(4) of FFDCA. 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 (59 FR 22951, 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) (Public Law
104-4).
    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

[[Page 52619]]

document, compared to the general population.

XI. Congressional Review Act

    The Congressional Review Act, 5 U.S.C. 801 et seq., generally
provides that before a rule may take effect, the agency promulgating
the rule must submit a rule report to each House of the Congress and to
the Comptroller General of the United States. 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 this rule in the Federal
Register. This rule is not a ``major rule'' as defined by 5 U.S.C. 804(2).
