This regulation establishes an exemption from the requirement of a tolerance for residues of α-[p-(1,1,3,3-tetramethylbutyl)phenyl]-ω-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 α-[p-(1,1,3,3-tetramethylbutyl)phenyl]-ω-hydroxypoly(oxyethylene).
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).

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 α-[p-(1,1,3,3-tetramethylbutyl)phenyl]-ω-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. 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 α-[p-(1,1,3,3-tetramethylbutyl)phenyl]-ω-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 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),α-[4-(1,1,3,3-tetramethylbutyl)phenyl]-ω-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.
Therefore, an exemption from the requirement of a tolerance is established for residues of α-[p-(1,1,3,3-tetramethylbutyl)phenyl]-ω-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).
