40 CFR Part 180

[EPA-HQ-OPP-2006-0550; FRL-8078-3]


2-Propenoic, 2-Methyl-, Polymers with Ethyl Acrylate and 
Polyethylene Glycol Methylacrylate C18-22 Alkyl Ethers; 
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, 2-methyl-, polymers with 
ethyl acrylate and polyethylene glycol methylacrylate C18-22 
alkyl ethers (CAS No. 888969-14-0) when used as an inert ingredient in 
a pesticide chemical formulation. The Lubrizol Corporation submitted a 
petition to EPA under the Federal Food, Drug, and Cosmetic Act (FFDCA), 
as amended by the Food Quality Protection Act of 1996 (FQPA) 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, 2-methyl-, polymers with ethyl acrylate and 
polyethylene glycol methylacrylate C18-22 alkyl ethers.

DATES: This regulation is effective July 26, 2006. Objections and 
requests for hearings must be received on or before September 25, 2006, 
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 January 25, 2006 (71 FR 4137) (FRL-7749-
9), EPA issued a notice pursuant to section 408 of the FFDCA, 21 U.S.C. 
346a, as amended by the FQPA (Public Law 104-170), announcing the 
filing of a pesticide petition (PP 5E6990) by The Lubrizol Corporation, 
29400 Lakeland Blvd., Wickliffe, OH 44092. 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, 2-methyl-, 
polymers with ethyl acrylate and polyethylene glycol methylacrylate 
C18-22 alkyl ethers; CAS No. 888969-14-0. That notice 
included a summary of the petition prepared by the petitioner. There 
were no comments in response to the notice of filing.
    Section 408(c)(2)(A)(i) of the 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 the 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 in residential settings, but does 
not include occupational exposure. Section 408(b)(2)(C) of the 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. Inert Ingredient Definition

    Inert ingredients are all ingredients that are not active 
ingredients as defined in 40 CFR 153.125 and include, but are not 
limited to, the following types of ingredients (except when they have a 
pesticidal efficacy of their own): Solvents such as alcohols and 
hydrocarbons; surfactants such as polyoxyethylene polymers and fatty 
acids; carriers such as clay and diatomaceous earth; thickeners such as 
carrageenan and modified cellulose; wetting, spreading, and dispersing 
agents; propellants in aerosol dispensers; microencapsulating agents;

[[Page 42283]]

and emulsifiers. The term ``inert'' is not intended to imply 
nontoxicity; the ingredient may or may not be chemically active. 
Generally, EPA has exempted inert ingredients from the requirement of a 
tolerance based on the low toxicity of the individual inert 
ingredients.

IV. 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 the 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 that should present 
minimal or no risk. The definition of a polymer is given in 40 CFR 
723.250(b). The following exclusion criteria for identifying these low 
risk polymers are described in 40 CFR 723.250(d).
    1. The polymer, 2-propenoic, 2-methyl-, polymers with ethyl 
acrylate and polyethylene glycol methylacrylate C18-22 alkyl 
ethers, is not a cationic polymer nor is it reasonably anticipated to 
become a cationic polymer in a natural aquatic environment.
    2. The polymer, 2-propenoic, 2-methyl-, polymers with ethyl 
acrylate and polyethylene glycol methylacrylate C18-22 alkyl 
ethers, does contain as an integral part of its composition the atomic 
elements carbon, hydrogen, and oxygen.
    3. The polymer, 2-propenoic, 2-methyl-, polymers with ethyl 
acrylate and polyethylene glycol methylacrylate C18-22 alkyl 
ethers, 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, 2-propenoic, 2-methyl-, polymers with ethyl 
acrylate and polyethylene glycol methylacrylate C18-22 alkyl 
ethers, is neither designed nor can it be reasonably anticipated to 
substantially degrade, decompose, or depolymerize.
    5. The polymer, 2-propenoic, 2-methyl-, polymers with ethyl 
acrylate and polyethylene glycol methylacrylate C18-22 alkyl 
ethers, 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, 2-propenoic, 2-methyl-, polymers with ethyl 
acrylate and polyethylene glycol methylacrylate C18-22 alkyl 
ethers, is not a water absorbing polymer with a number average 
molecular weight (MW) greater than or equal to 10,000 daltons.
    Additionally, the polymer, 2-propenoic, 2-methyl-, polymers with 
ethyl acrylate and polyethylene glycol methylacrylate C18-22 
alkyl ethers, also meets as required the following exemption criteria 
specified in 40 CFR 723.250(e).
    7. The number average molecular weight (MW) of the polymer, 2-
propenoic, 2-methyl-, polymers with ethyl acrylate and polyethylene 
glycol methylacrylate C18-22 alkyl ethers is 94,600, which 
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, 2-propenoic, 2-methyl-, polymers with ethyl acrylate and 
polyethylene glycol methylacrylate C18-22 alkyl ethers meet 
all the criteria for a polymer to be considered low risk under 40 CFR 
723.250. Based on its conformance to the above criteria, no mammalian 
toxicity is anticipated from dietary, inhalation, or dermal exposure to 
2-propenoic, 2-methyl-, polymers with ethyl acrylate and polyethylene 
glycol methylacrylate C18-22 alkyl ethers.

V. Aggregate Exposures

    For the purposes of assessing potential exposure under this 
exemption, EPA considered that 2-propenoic, 2-methyl-, polymers with 
ethyl acrylate and polyethylene glycol methylacrylate C18-22 
alkyl ethers 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, 2-methyl-, 
polymers with ethyl acrylate and polyethylene glycol methylacrylate 
C18-22 alkyl ethers is 94,600 daltons. Generally, a polymer 
of this size would be poorly absorbed through the intact 
gastrointestinal tract or through intact human skin. Since 2-propenoic, 
2-methyl-, polymers with ethyl acrylate and polyethylene glycol 
methylacrylate C18-22 alkyl ethers 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.

VI. 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.'' EPA does not 
have, at this time, available data to determine whether 2-propenoic, 2-
methyl-, polymers with ethyl acrylate and polyethylene glycol 
methylacrylate C18-22 alkyl ethers has a common mechanism of 
toxicity with other substances. Unlike other pesticides for which EPA 
has followed a cumulative risk approach based on a common mechanism of 
toxicity, EPA has not made a common mechanism of toxicity finding as to 
2-propenoic, 2-methyl-, polymers with ethyl acrylate and polyethylene 
glycol methylacrylate C18-22 alkyl ethers and any other 
substances and 2-propenoic, 2-methyl-, polymers with ethyl acrylate and 
polyethylene glycol methylacrylate C18-22 alkyl ethers does 
not appear to produce a toxic metabolite produced by other substances. 
For the purposes of this tolerance action, therefore, EPA has not 
assumed that 2-propenoic, 2-methyl-, polymers with ethyl acrylate and 
polyethylene glycol methylacrylate C18-22 alkyl ethers has 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 the policy statements released by EPA's Office of 
Pesticide Programs concerning common mechanism determinations and 
procedures for

[[Page 42284]]

cumulating effects from substances found to have a common mechanism on 
EPA's website at http://www.epa.gov/pesticides/cumulative.

VII. Additional Safety Factor for the Protection of Infants and 
Children

    Section 408 of the 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 2-propenoic, 2-methyl-, 
polymers with ethyl acrylate and polyethylene glycol methylacrylate 
C18-22 alkyl ethers, EPA has not used a safety factor 
analysis to assess the risk. For the same reasons the additional 
tenfold safety factor is unnecessary.

VIII. 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, 2-methyl-, polymers with 
ethyl acrylate and polyethylene glycol methylacrylate C18-22 
alkyl ethers.

IX. Other Considerations

A. Endocrine Disruptors

    There is no available evidence that 2-propenoic, 2-methyl-, 
polymers with ethyl acrylate and polyethylene glycol methylacrylate 
C18-22 alkyl ethers is an endocrine disruptor.

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 Tolerances

    The Agency is not aware of any country requiring a tolerance for 2-
propenoic, 2-methyl-, polymers with ethyl acrylate and polyethylene 
glycol methylacrylate C18-22 alkyl ethers nor have any CODEX 
Maximum Residue Levels (MRLs) been established for any food crops at 
this time.

X. Conclusion

    Accordingly, EPA finds that exempting residues of 2-propenoic, 2-
methyl-, polymers with ethyl acrylate and polyethylene glycol 
methylacrylate C18-22 alkyl ethers from the requirement of a 
tolerance will be safe.

XI. Statutory and Executive Order Reviews

    This final rule establishes an exemption from the tolerance 
requirement under section 408(d) of the FFDCA 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 rule has been exempted from review under Executive 
Order 12866 due to its lack of significance, this rule is not subject 
to Executive Order 13211, Actions Concerning Regulations That 
Significantly Affect Energy Supply, Distribution, or Use (66 FR 28355, 
May 22, 2001). 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., or 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). 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); 
or OMB review or any Agency action under Executive Order 13045, 
entitled Protection of Children from Environmental Health Risks and 
Safety Risks (62 FR 19885, April 23, 1997). 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 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 the FFDCA, such as the exemption 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. In addition, the Agency has determined that this 
action will not have a substantial direct effect on States, on the 
relationship between the national government and the States, or on the 
distribution of power and responsibilities among the various levels of 
government, as specified in Executive Order 13132, entitled Federalism 
(64 FR 43255, August 10, 1999). Executive Order 13132 requires EPA to 
develop an accountable process to ensure ``meaningful and timely input 
by State and local officials in the development of regulatory policies 
that have federalism implications.'' ``Policies that have federalism 
implications'' is defined in the Executive order to include regulations 
that have ``substantial direct effects on the States, on the 
relationship between the national government and the States, or on the 
distribution of power and responsibilities among the various levels of 
government.'' This final rule directly regulates growers, food 
processors, food handlers and food retailers, not States. This action 
does not alter the relationships or distribution of power and 
responsibilities established by Congress in the preemption provisions 
of section 408(n)(4) of the FFDCA. For these same reasons, the Agency 
has determined that this rule does not have any ``tribal implications'' 
as described in Executive Order 13175, entitled Consultation and 
Coordination with Indian Tribal Governments (65 FR 67249, November 6, 
2000). Executive Order 13175, requires EPA to develop an accountable 
process to ensure ``meaningful and timely input by tribal officials in 
the development of regulatory policies that have tribal implications.'' 
``Policies that have tribal implications'' is defined in the Executive 
order to include regulations that have ``substantial direct effects on 
one or more Indian tribes, on the relationship between the Federal 
Government and the Indian tribes, or on the distribution of power and 
responsibilities between the Federal Government and Indian tribes.'' 
This rule will not have substantial direct effects on tribal 
governments, on the relationship between the Federal Government and 
Indian tribes, or on the distribution of power and responsibilities 
between the Federal Government and Indian tribes, as specified in 
Executive Order 13175. Thus, Executive Order 13175 does not apply to 
this rule.

XII. Congressional Review Act

    The Congressional Review Act, 5 U.S.C. 801 et seq., as added by the 
Small Business Regulatory Enforcement Fairness Act of 1996, generally 
provides that before a rule may take effect, the Agency promulgating 
the rule must submit a rule report, which includes a copy of the rule, 
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

[[Page 42285]]

``major rule'' as defined by 5 U.S.C. 804(2).
