[EPA-HQ-OPP-2010-0272; FRL-8837-5]

 
2-propenoic acid, 2-methyl-, C12-16-alkyl esters, telomers with 
1-dodecanethiol, polyethylene-polypropylene glycol ether with propylene 
glycol monomethacrylate (1:1), and styrene 2,2'-(1,2-diazenediyl)bis[2-
methylbutanenitrile]-initiated; 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-methyl-, C12-16-
alkyl esters, telomers with 1-dodecanethiol, polyethylene-polypropylene 
glycol ether with propylene glycol monomethacrylate (1:1), and styrene 
2,2'-(1,2-diazenediyl)bis[2-methylbutanenitrile]-initiated, number 
average molecular weight (in AMU) 4000; when used as an inert 
ingredient in a pesticide chemical formulation 40 CFR 180.960. 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 2-propenoic acid, 2-methyl-, 
C12-16-alkyl esters, telomers with 1-dodecanethiol, polyethylene-
polypropylene glycol ether with propylene glycol monomethacrylate 
(1:1), and styrene 2,2'-(1,2-diazenediyl)bis[2-methylbutanenitrile]-
initiated on food or feed commodities.

II. Background and Statutory Findings

    In the Federal Register of June 8, 2010, (75 FR 32463) (FRL-8827-
5), EPA issued a notice pursuant to section 408 of FFDCA, 21 U.S.C. 
346a, announcing the receipt of a pesticide petition (PP 0E7702) filed 
by Clariant Corporation, P.O. Box 866, 625 East Catawba Avenue, Mount 
Holly, NC 28120. The petition requested that 40 CFR 180.960 be amended 
by establishing an exemption from the requirement of a tolerance for 
residues of 2-propenoic acid, 2-methyl-, C12-16-alkyl esters, telomers 
with 1-dodecanethiol, polyethylene-polypropylene glycol ether with 
propylene glycol monomethacrylate (1:1), and styrene 2,2'-(1,2-
diazenediyl)bis[2-methylbutanenitrile]-initiated, number average 
molecular weight (in AMU) 4,000; CAS No. 950207-35-9. 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 in response to this notice.
    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

[[Page 50928]]

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). 2-propenoic acid, 2- methyl-, C12-16-
alkyl esters, telomers with 1-dodecanethiol, polyethylene-polypropylene 
glycol ether with propylene glycol monomethacrylate (1:1), and styrene 
2,2'-(1,2-diazenediyl)bis[2-methylbutanenitrile]-initiated 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 4,000 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, 2-propenoic acid, 2-methyl-, C12-16-alkyl esters, telomers 
with 1-dodecanethiol, polyethylene-polypropylene glycol ether with 
propylene glycol monomethacrylate (1:1), and styrene 2,2'-(1,2-
diazenediyl)bis[2-methylbutanenitrile]-initiated 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 2-propenoic 
acid, 2-methyl-, C12-16-alkyl esters, telomers with 1-dodecanethiol, 
polyethylene-polypropylene glycol ether with propylene glycol 
monomethacrylate (1:1), and styrene 2,2'-(1,2-diazenediyl)bis[2-
methylbutanenitrile]-initiated.

IV. Aggregate Exposures

    For the purposes of assessing potential exposure under this 
exemption, EPA considered that 2-propenoic acid, 2-methyl-, C12-16-
alkyl esters, telomers with 1-dodecanethiol, polyethylene-polypropylene 
glycol ether with propylene glycol monomethacrylate (1:1), and styrene 
2,2'-(1,2-diazenediyl)bis[2-methylbutanenitrile]-initiated, 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 2-propenoic acid, 2-methyl-, C12-16-alkyl esters, 
telomers with 1-dodecanethiol, polyethylene-polypropylene glycol ether 
with propylene glycol monomethacrylate (1:1), and styrene 2,2'-(1,2-
diazenediyl)bis[2-methylbutanenitrile]-initiated is 4,000 daltons. 
Generally, a polymer of this size would be poorly absorbed through the 
intact gastrointestinal tract or through intact human skin. Since 2-
propenoic acid, 2-methyl-, C12-16-alkyl esters, telomers with 1-
dodecanethiol, polyethylene-polypropylene glycol ether with propylene 
glycol monomethacrylate (1:1), and styrene 2,2'-(1,2-diazenediyl)bis[2-
methylbutanenitrile]-initiated 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 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 2-propenoic acid, 2-methyl-, C12-16-alkyl esters, 
telomers with 1-dodecanethiol, polyethylene-polypropylene glycol ether 
with propylene glycol monomethacrylate (1:1), and styrene 2,2'-(1,2-
diazenediyl)bis[2-methylbutanenitrile]-initiated, to share a common 
mechanism of toxicity with any other substances, and 2-propenoic acid, 
2-methyl-, C12-16-alkyl esters, telomers with 1-dodecanethiol, 
polyethylene-polypropylene glycol ether with propylene glycol 
monomethacrylate (1:1), and styrene 2,2'-(1,2-diazenediyl)bis[2-
methylbutanenitrile]-initiated, does not appear to produce a toxic 
metabolite produced by other substances. For the purposes of this 
tolerance action, therefore, EPA has assumed that 2-propenoic acid, 2-
methyl-, C12-16-alkyl esters, telomers with 1-dodecanethiol, 
polyethylene-polypropylene glycol ether with propylene glycol 
monomethacrylate (1:1), and styrene 2,2'-(1,2-diazenediyl)bis[2-
methylbutanenitrile]-initiated, 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 
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

[[Page 50929]]

EPA concludes that a different margin of safety will be safe for 
infants and children. Due to the expected low toxicity of 2-propenoic 
acid, 2-methyl-, C12-16-alkyl esters, telomers with 1-dodecanethiol, 
polyethylene-polypropylene glycol ether with propylene glycol 
monomethacrylate (1:1), and styrene 2,2'-(1,2-diazenediyl)bis[2-
methylbutanenitrile]-initiated, 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 2-propenoic acid, 2-methyl-, C12-16-
alkyl esters, telomers with 1-dodecanethiol, polyethylene-polypropylene 
glycol ether with propylene glycol monomethacrylate (1:1), and styrene 
2,2'-(1,2-diazenediyl)bis[2-methylbutanenitrile]-initiated.

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 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 U.N. 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 2-propenoic acid, 2-
methyl-, C12-16-alkyl esters, telomers with 1-dodecanethiol, 
polyethylene-polypropylene glycol ether with propylene glycol 
monomethacrylate (1:1), and styrene 2,2'-(1,2-diazenediyl)bis[2-
methylbutanenitrile]-initiated.

IX. Conclusion

    Accordingly, EPA finds that exempting residues of 2-propenoic acid, 
2-methyl-, C12-16-alkyl esters, telomers with 1-dodecanethiol, 
polyethylene-polypropylene glycol ether with propylene glycol 
monomethacrylate (1:1), and styrene 2,2'-(1,2-diazenediyl)bis[2-
methylbutanenitrile]-initiated, number average molecular weight (in 
AMU) 4,000 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 (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) (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 
document, compared to the general population. If you received specific 
comments - consider addressing them here.

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).
