[EPA-HQ-OPP-2011-0525; FRL-9340-1]
[alpha]-[p-(1,1,3,3-Tetramethylbutyl)phenyl]-[omega]-
hydroxypoly(oxyethylene); Exemption From the Requirement of a Tolerance
AGENCY: Environmental Protection Agency (EPA).
ACTION: Final rule.
-----------------------------------------------------------------------
SUMMARY: This regulation establishes an exemption from the requirement
of a tolerance for residues of [alpha]-[p-(1,1,3,3-
tetramethylbutyl)phenyl]-[omega]-hydroxypoly(oxyethylene) (CAS Reg.
Nos. 9036-19-5, 9002-93-1) when used as an inert ingredient at levels
not to exceed 7% in pesticide formulations applied to growing crops and
raw agricultural commodities after harvest. The Joint Inerts Task
Force, Cluster Support Team Number 5 submitted a petition to EPA under
the Federal Food, Drug, and Cosmetic Act (FFDCA), requesting
establishment of an exemption from the requirement of a tolerance. This
regulation eliminates the need to establish a maximum permissible level
for residues of [alpha]-[p-(1,1,3,3-tetramethylbutyl)phenyl]-[omega]-
hydroxypoly(oxyethylene).
DATES: This regulation is effective May 11, 2012. Objections and
requests for hearings must be received on or before July 10, 2012, 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
In the Federal Register of August 26, 2011 (76 FR 53372) (FRL-8884-
9), EPA issued a notice pursuant to FFDCA section 408, 21 U.S.C. 346a,
announcing the filing of a pesticide petition (PP 1E7858) by Joint
Inerts Task Force, Cluster Support Team 5, c/o CropLife America, 1156
15th St. NW., Suite 400, Washington, DC 20005. The petition requested
that 40 CFR 180.910 be amended by establishing an exemption from the
requirement of a tolerance for residues of [alpha]-[p-(1,1,3,3-
tetramethylbutyl)phenyl]-[omega]-hydroxypoly(oxyethylene) (CAS Reg.
Nos. 9036-19-5, 9002-93-1) when used as an inert ingredient at levels
not to exceed 7% in pesticide formulations
[[Page 27629]]
applied to growing crops and raw agricultural commodities after
harvest. That notice referenced a summary of the petition prepared by
Joint Inerts Task Force, Cluster Support Team 5, the petitioner, which
is available in the docket, http://www.regulations.gov. There were no
comments received in response to the notice of filing.
Previously, in the Federal Register of May 17, 2010 (75 FR 27443)
(FRL-8826-3), EPA established a time-limited tolerance exemption for
[alpha]-[p-(1,1,3,3-tetramethylbutyl)phenyl]-[omega]-
hydroxypoly(oxyethylene) (herein referred to in this document as
octylphenol ethoxylate) with an expiration date of May 17, 2012. The 2-
year time limitation was established for two purposes:
1. To provide time for the development and submission of
confirmatory toxicity data to address equivocal results in the
available genotoxicity studies conducted on octylphenol ethoxylate (as
described in Unit IV.C., of the May 17, 2010 final rule); and
2. To provide additional time, should the initial testing not
confirm EPA's conclusion regarding the lack of a cancer concern, for
registrants to attain EPA approval of registration amendments for
reformulation of their pesticide products to remove octylphenol
ethoxylate and to replace existing products with reformulated products.
In establishing the time-limited tolerance exemption for
octylphenol ethoxylate, EPA stated that if the submitted data confirmed
its conclusion regarding a lack of cancer concern, the Agency intended
to remove the expiration date from the tolerance exemption prior to
expiration of the 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;
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. Aggregate Risk Assessment and Determination of Safety
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(b)(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 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 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 * * *.''
EPA establishes exemptions from the requirement of a tolerance only
in those cases where it can be clearly demonstrated 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(c)(2)(A), and the factors
specified in FFDCA section 408(c)(2)(B), EPA has reviewed the available
scientific data and other relevant information in support of this
action. EPA has sufficient data to assess the hazards of and to make a
determination on aggregate exposure for octylphenol ethoxylate
including exposure resulting from the exemption established by this
action.
In the Federal Register of May 17, 2010, EPA issued a final rule
establishing an exemption from the requirement of a tolerance for
residues of octylphenol ethoxylate when used as an inert ingredient at
levels not to exceed 7% in pesticide formulations applied to growing
crops and raw agricultural commodities after harvest under 40 CFR
180.910 with an expiration date of May 17, 2012. EPA has determined
that establishing an exemption from the requirement of a tolerance for
residues of octylphenol ethoxylate when used as an inert ingredient an
inert ingredient at levels not to exceed 7% in pesticide formulations
applied to growing crops and raw agricultural commodities after harvest
will not significantly change the risk assessments the Agency relied on
to support the May 17, 2010, tolerance action, as explained in this
unit.
As part of the Agency's conduct of the risk assessment in support
of the May 17, 2010, tolerance action, it was determined that there
were no acute, chronic, short- or intermediate term aggregate risks of
concern. With regards to aggregate cancer risk, the assessment
concluded that based on a weight of the evidence consideration of the
available data, the Agency believed that cancer risks would be
negligible. However, due to the equivocal findings in the mutagenicity
data base, the Agency asked for confirmatory data. Specifically, EPA
recommended that supporters of the octylphenol ethoxylate tolerance
exemption perform the following studies for confirmatory purposes:
A new Ames assay (OCSPP Harmonized Guideline 870.5100--Bacterial
reverse mutation test) and a mouse lymphoma assay (OCSPP Harmonized
Guideline 870.5300--in vitro Mammalian cell gene mutation test).
A bone marrow assay (OCSPP Harmonized Guideline 870.5395--Mammalian
erythrocyte micronucleus test).
Since in vivo mutagenicity studies such as the bone marrow assay
are generally regarded as more definitive than in vitro studies, and a
negative result in the bone marrow test may outweigh whatever results
are found in the Ames test and mouse lymphoma assay, supporters of the
octylphenol ethoxylate tolerance exemption were given the option of
conducting the mammalian erythrocyte micronucleus test in lieu of the
two in vitro mutagenicity studies. If those data did not confirm EPA's
cancer conclusion, then EPA would need 2-year cancer bioassays in the
mouse and rat (OCSPP
[[Page 27630]]
Harmonized Guideline 870.4200--Carcinogenicity (mouse) and OCSPP
Harmonized Guideline 870.4300--Combined Chronic Toxicity/
Carcinogenicity (rat)) to make a safety finding in support of the
tolerance exemption.
In response to the May 17, 2010, final rule, the Joint Inerts Task
Force, Cluster Support Team Number 5 conducted an in vivo Mouse Bone
Marrow Erythrocyte Micronucleus Test Following Oral Administration
(OCSPP Harmonized Test Guideline 870.5395) of the representative test
compound, poly(oxy-1,2-ethanediyl),[alpha]-[4-(1,1,3,3-
tetramethylbutyl)phenyl]-[omega]-hydroxy- (CAS Reg. No. 9002-93-1).
These data were submitted to the Agency on November 12, 2010 (Master
Record Identification Number 48293301).
The data were evaluated by EPA and it was determined that the test
substance did not induce numerical or structural chromosomal damage,
providing further confirmation that octylphenol ethoxylate is not of
concern for aggregate cancer risk. Further details of this evaluation
can be found at http://www.regulations.gov in the document
``Octylphenol Ethoxylates--(JITF CST 5 Inert Ingredients).--Review of
Confirmatory Mutagencity Toxicity Data'' in docket ID number EPA-HQ-
OPP-2011-0525.
Refer to the May 17, 2010, Federal Register document, available at
http://www.regulations.gov, for a detailed discussion of the aggregate
risk assessment and determination of safety.
Therefore, based on this information and the findings in the final
rule published in the Federal Register of May 17, 2010, EPA concludes
that there is a reasonable certainty that no harm will result to the
general population, or to infants and children from aggregate exposure
to octylphenol ethoxylate residues.
V. 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 Nation 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 octylphenol ethoxylate.
VI. Conclusions
Therefore, an exemption from the requirement of a tolerance is
established for residues of [alpha]-[p-(1,1,3,3-
tetramethylbutyl)phenyl]-[omega]-hydroxypoly(oxyethylene) when used as
an inert ingredient at levels not to exceed 7% in pesticide
formulations applied to growing crops and raw agricultural commodities
after harvest under 40 CFR 180.910.
VII. Statutory and Executive Order Reviews
This final rule establishes an exemption from the requirement of 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 types of actions 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 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).
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. 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) (Pub. L. 104-4).
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).
VIII. 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 final rule in the Federal
Register. This final rule is not a ``major rule'' as defined by 5
U.S.C. 804(2).
