40 CFR Part 180

[EPA-HQ-OPP-2013-0057; FRL-9381-2]

Castor Oil, Polymer With Adipic Acid, Linoleic Acid, Oleic Acid 
and Ricinoleic Acid; 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 castor oil, polymer with adipic acid, 
linoleic acid, oleic acid and ricinoleic acid (CAS Reg. No. 1357486-09-
9) when used as an inert ingredient in a pesticide formulation. Advance 
Polymer Technology 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 castor oil, 
polymer with adipic acid, linoleic acid, oleic acid and ricinoleic acid 
on food or feed commodities.

DATES: This regulation is effective April 3, 2013. Objections and 
requests for hearings must be received on or before June 3, 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 February 15, 2013 (78 FR 11126) (FRL-
9378-4), EPA issued a document pursuant to FFDCA section 408, 21 U.S.C. 
346a, announcing the receipt of a pesticide petition (PP 2E8040) filed 
by Advance Polymer Technology, 109 Conica Lane, P.O. Box 160, Harmony, 
PA 16037. The petition requested that 40 CFR 180.960 be amended by 
establishing an exemption from the requirement of a tolerance for 
residues of castor oil, polymer with adipic acid, linoleic acid, oleic 
acid and ricinoleic acid; CAS Reg. No. 1357486-09-9. That document 
included a summary of the petition prepared by the petitioner and 
solicited comments on the petitioner's request. The Agency received 1 
comment.
    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

[[Page 20030]]

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). Castor oil, polymer with adipic acid, 
linoleic acid, oleic acid and ricinoleic acid 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.
    7. The polymer does not contain certain perfluoroalkyl moieties 
consisting of a CF3- or longer chain length as specified 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); The polymer's number 
average MW of 3,500 daltons is greater than 1,000 daltons, and less 
than 10,000 daltons. The polymer contains less than 10% oligomeric 
material below MW 500 daltons, and less than 25% oligomeric material 
below MW 1,000 daltons, and the polymer does not contain any reactive 
functional groups.
    Thus, castor oil, polymer with adipic acid, linoleic acid, oleic 
acid and ricinoleic acid 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 castor oil, polymer with 
adipic acid, linoleic acid, oleic acid and ricinoleic acid.

IV. Aggregate Exposures

    For the purposes of assessing potential exposure under this 
exemption, EPA considered that castor oil, polymer with adipic acid, 
linoleic acid, oleic acid and ricinoleic acid 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 castor oil, polymer with adipic acid, linoleic acid, oleic acid 
and ricinoleic acid is 3,500 daltons. Generally, a polymer of this size 
would be poorly absorbed through the intact gastrointestinal tract or 
through intact human skin. Since castor oil, polymer with adipic acid, 
linoleic acid, oleic acid and ricinoleic acid 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 castor oil, polymer with adipic acid, linoleic 
acid, oleic acid and ricinoleic acid to share a common mechanism of 
toxicity with any other substances, and castor oil, polymer with adipic 
acid, linoleic acid, oleic acid and ricinoleic acid does not appear to 
produce a toxic metabolite produced by other substances. For the 
purposes of this tolerance action, therefore, EPA has assumed that 
castor oil, polymer with adipic acid, linoleic acid, oleic acid and 
ricinoleic acid 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 castor oil, polymer with 
adipic acid, linoleic acid, oleic acid and ricinoleic acid, EPA has not 
used a safety factor analysis to assess the risk.

[[Page 20031]]

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 castor oil, polymer with adipic acid, 
linoleic acid, oleic acid and ricinoleic acid.

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 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 castor oil, polymer with 
adipic acid, linoleic acid, oleic acid and ricinoleic acid.

C. Response to Comments

    The one comment received was from a private citizen who opposed the 
idea of raising tolerances for pesticide residues on products which are 
fed to humans. The Agency understands the commenter's concern and 
recognizes that some individuals believe that no residue of pesticides 
should be allowed. However, under the existing legal framework provided 
by section 408 of the FFDCA EPA is authorized to establish pesticide 
tolerances or exemptions where persons seeking such tolerances or 
exemptions have demonstrated that the pesticide meets the safety 
standard imposed by the statute.

IX. Conclusion

    Accordingly, EPA finds that exempting residues of castor oil, 
polymer with adipic acid, linoleic acid, oleic acid and ricinoleic acid 
from the requirement of a tolerance will be safe.

X. Statutory and Executive Order Reviews

    This final rule establishes an exemption from 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 
note).
    Since tolerances and exemptions that are established on the basis 
of a petition under FFDCA section 408(d), 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.
    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).
