General Information ENVIRONMENTAL PROTECTION AGENCY 40 CFR Part 180 [EPA–HQ–OPP–2014–0783; FRL–9941–49] Benzyl acetate; Exemption From the Requirement of a Tolerance Environmental Protection Agency (EPA). ACTION: Final rule. AGENCY: This regulation establishes an exemption from the requirement of a tolerance for residues of benzyl acetate (CAS Reg. No. 140–11–4), when used as an inert ingredient (solvent) in pesticide formulations applied to growing crops only under 40 CFR 180.920. Technology Sciences Group, on behalf of the Huntsman Corporation, 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 benzyl acetate. DATES: This regulation is effective February 12, 2016. Objections and requests for hearings must be received on or before April 12, 2016, and must be filed in accordance with the instructions provided in 40 CFR part 178 (see also Unit I.C. of the SUPPLEMENTARY INFORMATION).

Petition for Exemption In the Federal Register of Wednesday, March 4, 2015 (80 FR 11611) (FRL– 9922–68), EPA issued a document pursuant to FFDCA section 408, 21 U.S.C. 346a, announcing the filing of a pesticide petition ((PP) IN–10748) by Technology Sciences Group (TSG) 1150 18th Street NW., Suite 1000, Washington, DC 20036, on behalf of the Huntsman Corporation, 8600 Gosling Road, The Woodlands, TX 77381. The petition requested that 40 CFR 180.920 be amended by establishing an exemption from the requirement of a tolerance for residues of benzyl acetate (CAS Reg. No. 140–11–4) when used as an inert ingredient (solvent) in pesticide formulations applied to growing crops only. That document referenced a summary of the petition prepared by the Huntsman Corporation, the petitioner, which is available in the docket, https://www.regulations.gov. There were no comments received in response to the notice of filing. 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 E:\FR\FM\12FER1.SGM 12FER1 7474 Federal Register / Vol. 81, No. 29 / Friday, February 12, 2016 / Rules and Regulations A. Toxicological Profile low toxicity of the individual inert ingredients. srobinson on DSK5SPTVN1PROD with RULES 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 benzyl acetate including exposure resulting from the exemption established by this action. EPA’s assessment of exposures and risks associated with benzyl acetate follows. VerDate Sep<11>2014 16:06 Feb 11, 2016 Jkt 238001 EPA has evaluated the available toxicity data and considered their validity, completeness, and reliability as well as the relationship of the results of the studies 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. Specific information on the studies received and the nature of the adverse effects caused by benzyl acetate as well as the noobserved-adverse-effect-level (NOAEL) and the lowest-observed-adverse-effectlevel (LOAEL) from the toxicity studies are discussed in this unit. Benzyl acetate exhibits low levels of toxicity via the dermal route of exposure in rabbits and inhalation and oral routes of exposure in rats. It is mildly irritating to the skin and minimally irritating to the eyes in rabbits. It is not a skin sensitizer in guinea pigs. In a 13-week feeding study in the rat, atrophic seminiferous tubules were observed in male rats at dose levels of 12,500 parts per millions (ppm) (equivalent to 900 milligrams/kilogram/ day (mg/kg/day)). The NOAEL was identified as 6,250 ppm (460 mg/kg/ day). In mice, following 13 weeks of exposure via the diet, decreased body weight and food consumption were observed at all doses. The LOAEL was 3,130 ppm (425 mg/kg/day). A NOAEL was not established. In a developmental toxicity study in the rat, maternal and fetal toxicity were observed at 1,000 mg/kg/day. Maternal toxicity was manifested as decreased body weight and fetal toxicity was manifested as reduced body weights, increased incidence of dilation of the renal pelvis and skeletal variations. Although qualitative fetal susceptibility is observed, fetal effects occur in the presence of maternal toxicity and a clear NOAEL of 500 mg/kg/day was established for maternal and developmental toxicity. The potential for benzyl acetate to be genotoxic was evaluated in a battery of in vivo mammalian genotoxicity studies. It was negative in the Ames assay (with and without metabolic activation), sister chromatid exchange assay, Chinese hamster ovary cell assay, mouse micronucleus assay and in the dominant lethal assay in Drosophila. However, it gave a positive response in the mouse lymphoma assay. Since other chromosomal aberrations assays as well as gene mutation assays and a dominant lethal assay gave a negative response, it is concluded that benzyl acetate is unlikely to be mutagenic. PO 00000 Frm 00030 Fmt 4700 Sfmt 4700 Evidence of neurotoxicity and neuronal degeneration was identified in the 13-week studies in rats and mice. Signs of neurotoxicity included tremors and ataxia that were associated with the degeneration of the glial cells in the cerebellum and hippocampus at the doses ≥12,500 ppm (≥2,000 mg/kg/day). Since these effects were induced at doses above the limit dose (1,000 mg/ kg/day) and the established cRfD of 1.10 mg/kg/day, will be protective of these effects, the concern is low for these effects. There is evidence that benzyl acetate suppresses immune function in mammalian systems in the rat however this effect occurs only at a dose that is lethal and well above the limit dose. In the 13-week feeding study in the rat, a decrease in the cellular components of the bone marrow, thymus and lymphoid follicles was observed at 50,000 ppm (3,900 mg/kg/day for males and 4,500 mg/kg/day for females), the highest dose tested and well above the limit dose. The NOAEL for this study was 12,500 ppm (900 mg/kg/day). The potential for immunotoxicity is not of concern because the effects occur well above the limit dose and the exposure to benzyl acetate through the proposed use is unlikely to occur at such a high dose. The carcinogenicity of benzyl acetate in F344/N rats, and B6C3F1 mice using was evaluated using the gavage method of administration and corn oil as a vehicle. There were indications that benzyl acetate increased the incidences of pancreatic acinar cell adenomas in male rats and the incidences of hepatocellular adenomas and forestomach neoplasms in male and female mice. Because of the confounding effects of corn oil on the incidences of pancreatic neoplasm and because of the controversy over the use of the gavage route of administration, the National Toxicology Program (NTP) decided to re-study benzyl acetate using the dosed feed route of administration. In 1993, the NTP conducted a second set of carcinogenicity studies in rats and mice using the dose feed route of administration. Benzyl acetate was administered via the diet to rats and mice at doses up to 12,000 ppm (510/ 575 mg/kg/day, male/female). Toxicity was not observed in rats at any dose. In mice, males and females exhibited reduced body weight throughout the entire study at 345/375 mg/kg/day. There was no evidence of carcinogenicity in mice and rats. Since the exposure to benzyl acetate is likely to occur via the dietary route in humans and there is some uncertainty about the use of corn oil in the gavage study, it is concluded that benzyl acetate is E:\FR\FM\12FER1.SGM 12FER1 Federal Register / Vol. 81, No. 29 / Friday, February 12, 2016 / Rules and Regulations srobinson on DSK5SPTVN1PROD with RULES unlikely to be carcinogenic to humans via the dietary route of exposure. In metabolism studies approximately 90% of benzyl acetate is excreted as metabolites primarily in the urine after oral or percutaneous administration. None was detected in the adipose tissue, blood, kidney, liver, lung, muscle, skin or stomach. The major metabolite in the urine was hippuric acid and 95 to 99% of the excreted dose was in this form. Less than 4% remained in the carcass. B. Toxicological Points of Departure/ Levels of Concern Once a pesticide’s toxicological profile is determined, EPA identifies toxicological points of departure (POD) and levels of concern to use in evaluating the risk posed by human exposure to the pesticide. For hazards that have a threshold below which there is no appreciable risk, the toxicological POD is used as the basis for derivation of reference values for risk assessment. PODs are developed based on a careful analysis of the doses in each toxicological study to determine the dose at which no adverse effects are observed (the NOAEL) and the lowest dose at which adverse effects of concern are identified (the LOAEL). Uncertainty/ safety factors are used in conjunction with the POD to calculate a safe exposure level—generally referred to as a population-adjusted dose (PAD) or a reference dose (RfD)—and a safe margin of exposure (MOE). For non-threshold risks, the Agency assumes that any amount of exposure will lead to some degree of risk. Thus, the Agency estimates risk in terms of the probability of an occurrence of the adverse effect expected in a lifetime. For more information on the general principles EPA uses in risk characterization and a complete description of the risk assessment process, see https:// www.epa.gov/pesticides/factsheets/ riskassess.htm. The point of departure for benzyl acetate is 110 mg/kg/day from the NTP 2-year carcinogenicity study in mice (dietary study) based on decreased in body weights in both sexes at the LOAEL of 345/375 mg/kg/day. There was no NOAEL observed in a 90-day toxicity study in mice based on the effects on body weights seen at all doses (lowest dose tested was 3,130 ppm; equal to 425 mg/kg/day); however, in a carcinogenicity study in mice no effects on body weight were seen at 110 mg/kg/ day, therefore, the NOAEL for the carcinogenicity study would be protective of decreased body weights seen in a 90-day study in mice. Therefore, 90-day toxicity study in mice was not selected. This endpoint was VerDate Sep<11>2014 16:06 Feb 11, 2016 Jkt 238001 used for all exposure scenarios. The dermal absorption and inhalation factors were 100%. The Agency applied an interspecies uncertainty factor (10X) and an intraspecies uncertainty factor (10X); the FQPA safety factor was reduced to 1X. C. Exposure Assessment 1. Dietary exposure from food and feed uses. In evaluating dietary exposure to benzyl acetate, EPA considered exposure under the proposed exemption from the requirement of a tolerance. EPA assessed dietary exposures from benzyl acetate in food as follows: An acute dietary risk assessment was not conducted because no endpoint of concern following a single exposure was identified in the available studies. A chronic dietary exposure assessment was completed and performed using the Dietary Exposure Evaluation Model DEEM–FCIDTM, Version 3.16, which includes food consumption information from the U.S. Department of Agriculture’s National Health and Nutrition Examination Survey, ‘‘What We Eat In America’’, (NHANES/ WWEIA). This dietary survey was conducted from 2003 to 2008. In the absence of actual residue data, the inert ingredient evaluation is based on a highly conservative model that assumes that the residue level of the inert ingredient would be no higher than the highest established tolerance for an active ingredient on a given commodity. Implicit in this assumption is that there would be similar rates of degradation between the active and inert ingredient (if any) and that the concentration of inert ingredient in the scenarios leading to these highest of tolerances would be no higher than the concentration of the active ingredient. The model assumes 100 percent crop treated (PCT) for all crops and that every food eaten by a person each day has tolerance-level residues. A complete description of the general approach taken to assess inert ingredient risks in the absence of residue data is contained in the memorandum entitled ‘‘Alkyl Amines Polyalkoxylates (Cluster 4): Acute and Chronic Aggregate (Food and Drinking Water) Dietary Exposure and Risk Assessments for the Inerts’’ (D361707, S. Piper, 2/25/09) and can be found at https://www.regulations.gov in docket ID number EPA–HQ–OPP–2008–0738. Nonpesticidal dietary exposure to benzyl acetate (e.g., use as a food additive (flavoring agent) were also considered as part of aggregate chronic dietary risk assessment. 2. Dietary exposure from drinking water. For the purpose of the screening- PO 00000 Frm 00031 Fmt 4700 Sfmt 4700 7475 level dietary risk assessment to support this request for an exemption from the requirement of a tolerance for benzyl acetate, a conservative drinking water concentration value of 100 ppb based on screening level modeling was used to assess the contribution to drinking water for the chronic dietary risk assessments for parent compound. These values were directly entered into the dietary exposure model. 3. From non-dietary exposure. The term ‘‘residential exposure’’ is used in this document to refer to nonoccupational, non-dietary exposure (e.g., textiles (clothing and diapers), carpets, swimming pools, and hard surface disinfection on walls, floors, tables). Based upon the requested use of benzyl acetate, the Agency does not expect non-occupational, non-dietary exposures. However, there is a potential for residential exposure via nonpesticidal uses such as use in cosmetics and other, pesticide uses, once it is approved. The residential exposure could occur via ingestion products containing benzyl acetate, and via dermal and inhalation routes of exposure through use of products containing benzyl acetate in residential settings. These residential pesticide exposures are considered short-term and intermediate-term in nature. Residential exposures to benzyl acetate as the result of its use as a cosmetic ingredient may be short-, intermediate- or long-term in nature. The aggregate-short term exposure assessment for benzyl acetate considers exposures from the pesticidal and nonpesticidal uses (i.e., flavoring agent and cosmetic ingredient) and would be protective of any potential long-term exposure to benzyl acetate resulting from its use in cosmetics as the same toxicological point of departure is used for all exposure durations and the average daily exposure estimates for cosmetic use is conservatively applied to all exposure durations. 4. 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 benzyl acetate to share a common mechanism of toxicity with any other substances, and benzyl acetate does not appear to produce a toxic metabolite produced by other substances. For the purposes of this tolerance action, therefore, EPA has assumed that benzyl E:\FR\FM\12FER1.SGM 12FER1 7476 Federal Register / Vol. 81, No. 29 / Friday, February 12, 2016 / Rules and Regulations srobinson on DSK5SPTVN1PROD with RULES acetate 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 https:// www.epa.gov/pesticides/cumulative. D. Safety Factor for Infants and Children 1. In general. Section 408(b)(2)(C) of FFDCA provides that EPA shall apply an additional tenfold (10X) 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 database on toxicity and exposure unless EPA determines based on reliable data that a different margin of safety will be safe for infants and children. This additional margin of safety is commonly referred to as the FQPA Safety Factor (SF). In applying this provision, EPA either retains the default value of 10X, or uses a different additional safety factor when reliable data available to EPA support the choice of a different factor. 2. Prenatal and postnatal sensitivity Qualitative fetal susceptibility was observed in the developmental study in rats. Maternal (decrease in body weight) and fetal (reduced body weights, increased incidence of dilation of the renal pelvis and skeletal variations) toxicity were observed at 1,000 mg/kg/ day, the limit dose. Since fetal toxicity occurs in the presence of maternal toxicity and a clear NOAEL of 500 mg/ kg/day was established, the established cRfD (1.10 mg/kg/day) will be protective of these effects. The potential for reproduction toxicity was observed in the 13-week dietary study in rats. Atrophy of seminiferous tubules was observed in males at 12,500 ppm (900 mg/kg/day). However, the concern for reproduction toxicity is low since effects occurred at a high dose and a clear NOAEL of 6,250 ppm (460 mg/kg/ day) was established. Therefore, the established cRfD will be protective of this effect. In addition, no female reproductive parameters were affected in the developmental toxicity study in rats. 3. Conclusion. EPA has determined that reliable data show the safety of infants and children would be adequately protected if the FQPA SF were reduced to 1X. That decision is based on the following findings: i. The toxicity database for benzyl acetate contains the following studies that are adequate to evaluate the potential toxicity of benzyl acetate for infants and children: A thirteen week VerDate Sep<11>2014 16:06 Feb 11, 2016 Jkt 238001 feeding study in the rat, a 13-week feeding study in the mouse, a developmental toxicity study in the rat, several in vivo and in vitro mutagenicity studies, and carcinogenicity studies in mice and rats via gavage and dietary studies. ii. Evidence of neurotoxicity and neuronal degeneration seen in a thirteen-week study was determined not to exceed levels of concern since the effects occurred at doses that were well above the limit dose (1,000 mg/kg/day). The established cRfD is 1.10 mg/kg/day therefore is protective of these effects. iii. Qualitative fetal susceptibility was observed in the developmental study in rats. Maternal (decrease in body weight) and fetal (reduced body weights, increased incidence of dilation of the renal pelvis and skeletal variations) toxicity were observed at 1,000 mg/kg/ day, the limit dose. Since fetal toxicity occurs in the presence of maternal toxicity and a clear NOAEL of 500 mg/ kg/day was established, the established cRfD (1.10 mg/kg/day) will be protective of these effects. The potential for reproduction toxicity was observed in the 13-week dietary study in rats. Atrophy of seminiferous tubules was observed in males at 12,500 ppm (900 mg/kg/day). However, the concern for reproductive toxicity is low since effects occurred at a high dose and a clear NOAEL of 6,250 ppm (460 mg/kg/day) was established. iv. There are no residual uncertainties identified in the exposure databases. The dietary food exposure assessments were performed based on 100% CT and tolerance-level residues. EPA made conservative (protective) assumptions in the ground and surface water modeling used to assess exposure to benzyl acetate in drinking water. EPA used similarly conservative assumptions to assess post-application exposure of children as well as incidental oral exposure of toddlers. These assessments will not underestimate the exposure and risks posed by benzyl acetate. E. Aggregate Risks and Determination of Safety Section EPA determines whether acute and chronic dietary pesticide exposures are safe by comparing aggregate exposure estimates to the acute PAD (aPAD) and chronic PAD (cPAD). For linear cancer risks, EPA calculates the lifetime probability of acquiring cancer given the estimated aggregate exposure. Short-, intermediate-, and chronic-term risks are evaluated by comparing the estimated aggregate food, water, and residential exposure to the appropriate PODs to ensure that an adequate MOE exists. PO 00000 Frm 00032 Fmt 4700 Sfmt 4700 1. Acute risk. An acute aggregate risk assessment takes into account acute exposure estimates from dietary consumption of food and drinking water. No adverse effect resulting from a single oral exposure was identified and no acute dietary endpoint was selected. Therefore, benzyl acetate is not expected to pose an acute risk. 2. Chronic risk. Using the exposure assumptions described in this unit for chronic exposure, EPA has concluded that chronic exposure to benzyl acetate from food and water will utilize 62.9% of the cPAD for children ages 1 to 2, the population group receiving the greatest exposure. 3. Short-term risk. Short-term aggregate exposure takes into account short-term residential exposure plus chronic exposure to food and water (considered to be a background exposure level). Benzyl acetate is likely to be used as an inert ingredient in pesticide products that are registered for uses that could result in short-term residential exposure, and the Agency has determined that it is appropriate to aggregate chronic exposure through food and water with short-term residential exposures to benzyl acetate. Using the exposure assumptions described in this unit for screening-level short-term exposures, EPA has concluded the combined short-term food, water, and residential exposures result in aggregate MOEs of 150 for children ages 1 to 2 and 260 for adults. Because EPA’s level of concern for benzyl acetate is a MOE of 100 or below, these MOEs are not of concern. 4. Intermediate-term risk. Intermediate-term aggregate exposure takes into account intermediate-term residential exposure plus chronic exposure to food and water (considered to be a background exposure level). Because no intermediate-term adverse effect was identified, benzyl acetate is not expected to pose an intermediateterm risk. 5. Aggregate cancer risk for U.S. population. Based on the lack of evidence of carcinogenicity in the dietary carcinogenicity studies in mice and rats, benzyl acetate is not expected to pose a cancer risk to humans. 6. Determination of safety. Based on these risk assessments, 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 benzyl acetate residues. V. Analytical Enforcement Methodology An analytical method is not required for enforcement purposes since the E:\FR\FM\12FER1.SGM 12FER1 7477 Federal Register / Vol. 81, No. 29 / Friday, February 12, 2016 / Rules and Regulations Agency is establishing an exemption from the requirement of a tolerance without any numerical limitation. VI. Conclusions Therefore, an exemption from the requirement of a tolerance is established under 40 CFR 180.920 for benzyl aceetate (CAS Reg. No. 140–11–4) when used as an inert ingredient (solvent) in pesticide formulations applied to growing crops only. srobinson on DSK5SPTVN1PROD with RULES VII. Statutory and Executive Order Reviews This action 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 action has been exempted from review under Executive Order 12866, this action 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 action 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 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 action 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 VerDate Sep<11>2014 17:24 Feb 11, 2016 Jkt 238001 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 action. In addition, this action does not impose any enforceable duty or contain any unfunded mandate as described under Title II of the Unfunded Mandates Reform Act (UMRA) (2 U.S.C. 1501 et seq.). 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 (NTTAA) (15 U.S.C. 272 note).

Benzyl acetate; 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 benzyl acetate (CAS Reg. No. 140-11-4), 
when used as an inert ingredient (solvent) in pesticide formulations 
applied to growing crops only under 40 CFR 180.920. Technology Sciences 
Group, on behalf of the Huntsman Corporation, 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 benzyl acetate.

DATES: This regulation is effective February 12, 2016. Objections and 
requests for hearings must be received on or before April 12, 2016, and 
must be filed in accordance with the instructions provided in 40 CFR

II. Petition for Exemption

    In the Federal Register of Wednesday, March 4, 2015 (80 FR 11611) 
(FRL-9922-68), EPA issued a document pursuant to FFDCA section 408, 21 
U.S.C. 346a, announcing the filing of a pesticide petition ((PP) IN-
10748) by Technology Sciences Group (TSG) 1150 18th Street NW., Suite 
1000, Washington, DC 20036, on behalf of the Huntsman Corporation, 8600 
Gosling Road, The Woodlands, TX 77381. The petition requested that 40 
CFR 180.920 be amended by establishing an exemption from the 
requirement of a tolerance for residues of benzyl acetate (CAS Reg. No. 
140-11-4) when used as an inert ingredient (solvent) in pesticide 
formulations applied to growing crops only. That document referenced a 
summary of the petition prepared by the Huntsman Corporation, the 
petitioner, which is available in the docket, https://www.regulations.gov. There were no comments received in response to the 
notice of filing.

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

[[Page 7474]]

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 benzyl acetate including 
exposure resulting from the exemption established by this action. EPA's 
assessment of exposures and risks associated with benzyl acetate 
follows.

A. Toxicological Profile

    EPA has evaluated the available toxicity data and considered their 
validity, completeness, and reliability as well as the relationship of 
the results of the studies 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. Specific information on the studies received and the nature 
of the adverse effects caused by benzyl acetate as well as the no-
observed-adverse-effect-level (NOAEL) and the lowest-observed-adverse-
effect-level (LOAEL) from the toxicity studies are discussed in this 
unit.
    Benzyl acetate exhibits low levels of toxicity via the dermal route 
of exposure in rabbits and inhalation and oral routes of exposure in 
rats. It is mildly irritating to the skin and minimally irritating to 
the eyes in rabbits. It is not a skin sensitizer in guinea pigs.
    In a 13-week feeding study in the rat, atrophic seminiferous 
tubules were observed in male rats at dose levels of 12,500 parts per 
millions (ppm) (equivalent to 900 milligrams/kilogram/day (mg/kg/day)). 
The NOAEL was identified as 6,250 ppm (460 mg/kg/day). In mice, 
following 13 weeks of exposure via the diet, decreased body weight and 
food consumption were observed at all doses. The LOAEL was 3,130 ppm 
(425 mg/kg/day). A NOAEL was not established.
    In a developmental toxicity study in the rat, maternal and fetal 
toxicity were observed at 1,000 mg/kg/day. Maternal toxicity was 
manifested as decreased body weight and fetal toxicity was manifested 
as reduced body weights, increased incidence of dilation of the renal 
pelvis and skeletal variations. Although qualitative fetal 
susceptibility is observed, fetal effects occur in the presence of 
maternal toxicity and a clear NOAEL of 500 mg/kg/day was established 
for maternal and developmental toxicity.
    The potential for benzyl acetate to be genotoxic was evaluated in a 
battery of in vivo mammalian genotoxicity studies. It was negative in 
the Ames assay (with and without metabolic activation), sister 
chromatid exchange assay, Chinese hamster ovary cell assay, mouse 
micronucleus assay and in the dominant lethal assay in Drosophila. 
However, it gave a positive response in the mouse lymphoma assay. Since 
other chromosomal aberrations assays as well as gene mutation assays 
and a dominant lethal assay gave a negative response, it is concluded 
that benzyl acetate is unlikely to be mutagenic.
    Evidence of neurotoxicity and neuronal degeneration was identified 
in the 13-week studies in rats and mice. Signs of neurotoxicity 
included tremors and ataxia that were associated with the degeneration 
of the glial cells in the cerebellum and hippocampus at the doses 
>=12,500 ppm (>=2,000 mg/kg/day). Since these effects were induced at 
doses above the limit dose (1,000 mg/kg/day) and the established cRfD 
of 1.10 mg/kg/day, will be protective of these effects, the concern is 
low for these effects.
    There is evidence that benzyl acetate suppresses immune function in 
mammalian systems in the rat however this effect occurs only at a dose 
that is lethal and well above the limit dose. In the 13-week feeding 
study in the rat, a decrease in the cellular components of the bone 
marrow, thymus and lymphoid follicles was observed at 50,000 ppm (3,900 
mg/kg/day for males and 4,500 mg/kg/day for females), the highest dose 
tested and well above the limit dose. The NOAEL for this study was 
12,500 ppm (900 mg/kg/day). The potential for immunotoxicity is not of 
concern because the effects occur well above the limit dose and the 
exposure to benzyl acetate through the proposed use is unlikely to 
occur at such a high dose.
    The carcinogenicity of benzyl acetate in F344/N rats, 
and B6C3F1 mice using was evaluated using the gavage method 
of administration and corn oil as a vehicle. There were indications 
that benzyl acetate increased the incidences of pancreatic acinar cell 
adenomas in male rats and the incidences of hepatocellular adenomas and 
forestomach neoplasms in male and female mice. Because of the 
confounding effects of corn oil on the incidences of pancreatic 
neoplasm and because of the controversy over the use of the gavage 
route of administration, the National Toxicology Program (NTP) decided 
to re-study benzyl acetate using the dosed feed route of 
administration. In 1993, the NTP conducted a second set of 
carcinogenicity studies in rats and mice using the dose feed route of 
administration. Benzyl acetate was administered via the diet to rats 
and mice at doses up to 12,000 ppm (510/575 mg/kg/day, male/female). 
Toxicity was not observed in rats at any dose. In mice, males and 
females exhibited reduced body weight throughout the entire study at 
345/375 mg/kg/day. There was no evidence of carcinogenicity in mice and 
rats. Since the exposure to benzyl acetate is likely to occur via the 
dietary route in humans and there is some uncertainty about the use of 
corn oil in the gavage study, it is concluded that benzyl acetate is

[[Page 7475]]

unlikely to be carcinogenic to humans via the dietary route of 
exposure.
    In metabolism studies approximately 90% of benzyl acetate is 
excreted as metabolites primarily in the urine after oral or 
percutaneous administration. None was detected in the adipose tissue, 
blood, kidney, liver, lung, muscle, skin or stomach. The major 
metabolite in the urine was hippuric acid and 95 to 99% of the excreted 
dose was in this form. Less than 4% remained in the carcass.

B. Toxicological Points of Departure/Levels of Concern

    Once a pesticide's toxicological profile is determined, EPA 
identifies toxicological points of departure (POD) and levels of 
concern to use in evaluating the risk posed by human exposure to the 
pesticide. For hazards that have a threshold below which there is no 
appreciable risk, the toxicological POD is used as the basis for 
derivation of reference values for risk assessment. PODs are developed 
based on a careful analysis of the doses in each toxicological study to 
determine the dose at which no adverse effects are observed (the NOAEL) 
and the lowest dose at which adverse effects of concern are identified 
(the LOAEL). Uncertainty/safety factors are used in conjunction with 
the POD to calculate a safe exposure level--generally referred to as a 
population-adjusted dose (PAD) or a reference dose (RfD)--and a safe 
margin of exposure (MOE). For non-threshold risks, the Agency assumes 
that any amount of exposure will lead to some degree of risk. Thus, the 
Agency estimates risk in terms of the probability of an occurrence of 
the adverse effect expected in a lifetime. For more information on the 
general principles EPA uses in risk characterization and a complete 
description of the risk assessment process, see https://www.epa.gov/pesticides/factsheets/riskassess.htm.
    The point of departure for benzyl acetate is 110 mg/kg/day from the 
NTP 2-year carcinogenicity study in mice (dietary study) based on 
decreased in body weights in both sexes at the LOAEL of 345/375 mg/kg/
day. There was no NOAEL observed in a 90-day toxicity study in mice 
based on the effects on body weights seen at all doses (lowest dose 
tested was 3,130 ppm; equal to 425 mg/kg/day); however, in a 
carcinogenicity study in mice no effects on body weight were seen at 
110 mg/kg/day, therefore, the NOAEL for the carcinogenicity study would 
be protective of decreased body weights seen in a 90-day study in mice. 
Therefore, 90-day toxicity study in mice was not selected. This 
endpoint was used for all exposure scenarios. The dermal absorption and 
inhalation factors were 100%. The Agency applied an interspecies 
uncertainty factor (10X) and an intraspecies uncertainty factor (10X); 
the FQPA safety factor was reduced to 1X.

C. Exposure Assessment

    1. Dietary exposure from food and feed uses. In evaluating dietary 
exposure to benzyl acetate, EPA considered exposure under the proposed 
exemption from the requirement of a tolerance. EPA assessed dietary 
exposures from benzyl acetate in food as follows:
    An acute dietary risk assessment was not conducted because no 
endpoint of concern following a single exposure was identified in the 
available studies. A chronic dietary exposure assessment was completed 
and performed using the Dietary Exposure Evaluation Model DEEM-
FCID\TM\, Version 3.16, which includes food consumption information 
from the U.S. Department of Agriculture's National Health and Nutrition 
Examination Survey, ``What We Eat In America'', (NHANES/WWEIA). This 
dietary survey was conducted from 2003 to 2008. In the absence of 
actual residue data, the inert ingredient evaluation is based on a 
highly conservative model that assumes that the residue level of the 
inert ingredient would be no higher than the highest established 
tolerance for an active ingredient on a given commodity. Implicit in 
this assumption is that there would be similar rates of degradation 
between the active and inert ingredient (if any) and that the 
concentration of inert ingredient in the scenarios leading to these 
highest of tolerances would be no higher than the concentration of the 
active ingredient. The model assumes 100 percent crop treated (PCT) for 
all crops and that every food eaten by a person each day has tolerance-
level residues. A complete description of the general approach taken to 
assess inert ingredient risks in the absence of residue data is 
contained in the memorandum entitled ``Alkyl Amines Polyalkoxylates 
(Cluster 4): Acute and Chronic Aggregate (Food and Drinking Water) 
Dietary Exposure and Risk Assessments for the Inerts'' (D361707, S. 
Piper, 2/25/09) and can be found at https://www.regulations.gov in 
docket ID number EPA-HQ-OPP-2008-0738. Nonpesticidal dietary exposure 
to benzyl acetate (e.g., use as a food additive (flavoring agent) were 
also considered as part of aggregate chronic dietary risk assessment.
    2. Dietary exposure from drinking water. For the purpose of the 
screening-level dietary risk assessment to support this request for an 
exemption from the requirement of a tolerance for benzyl acetate, a 
conservative drinking water concentration value of 100 ppb based on 
screening level modeling was used to assess the contribution to 
drinking water for the chronic dietary risk assessments for parent 
compound. These values were directly entered into the dietary exposure 
model.
    3. From non-dietary exposure. The term ``residential exposure'' is 
used in this document to refer to non-occupational, non-dietary 
exposure (e.g., textiles (clothing and diapers), carpets, swimming 
pools, and hard surface disinfection on walls, floors, tables).
    Based upon the requested use of benzyl acetate, the Agency does not 
expect non-occupational, non-dietary exposures. However, there is a 
potential for residential exposure via non-pesticidal uses such as use 
in cosmetics and other, pesticide uses, once it is approved. The 
residential exposure could occur via ingestion products containing 
benzyl acetate, and via dermal and inhalation routes of exposure 
through use of products containing benzyl acetate in residential 
settings. These residential pesticide exposures are considered short-
term and intermediate-term in nature. Residential exposures to benzyl 
acetate as the result of its use as a cosmetic ingredient may be short-
, intermediate- or long-term in nature. The aggregate-short term 
exposure assessment for benzyl acetate considers exposures from the 
pesticidal and nonpesticidal uses (i.e., flavoring agent and cosmetic 
ingredient) and would be protective of any potential long-term exposure 
to benzyl acetate resulting from its use in cosmetics as the same 
toxicological point of departure is used for all exposure durations and 
the average daily exposure estimates for cosmetic use is conservatively 
applied to all exposure durations.
    4. 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 benzyl 
acetate to share a common mechanism of toxicity with any other 
substances, and benzyl acetate does not appear to produce a toxic 
metabolite produced by other substances. For the purposes of this 
tolerance action, therefore, EPA has assumed that benzyl

[[Page 7476]]

acetate 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 https://www.epa.gov/pesticides/cumulative.

D. Safety Factor for Infants and Children

    1. In general. Section 408(b)(2)(C) of FFDCA provides that EPA 
shall apply an additional tenfold (10X) 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 database on toxicity 
and exposure unless EPA determines based on reliable data that a 
different margin of safety will be safe for infants and children. This 
additional margin of safety is commonly referred to as the FQPA Safety 
Factor (SF). In applying this provision, EPA either retains the default 
value of 10X, or uses a different additional safety factor when 
reliable data available to EPA support the choice of a different 
factor.
    2. Prenatal and postnatal sensitivity Qualitative fetal 
susceptibility was observed in the developmental study in rats. 
Maternal (decrease in body weight) and fetal (reduced body weights, 
increased incidence of dilation of the renal pelvis and skeletal 
variations) toxicity were observed at 1,000 mg/kg/day, the limit dose. 
Since fetal toxicity occurs in the presence of maternal toxicity and a 
clear NOAEL of 500 mg/kg/day was established, the established cRfD 
(1.10 mg/kg/day) will be protective of these effects. The potential for 
reproduction toxicity was observed in the 13-week dietary study in 
rats. Atrophy of seminiferous tubules was observed in males at 12,500 
ppm (900 mg/kg/day). However, the concern for reproduction toxicity is 
low since effects occurred at a high dose and a clear NOAEL of 6,250 
ppm (460 mg/kg/day) was established. Therefore, the established cRfD 
will be protective of this effect. In addition, no female reproductive 
parameters were affected in the developmental toxicity study in rats.
    3. Conclusion. EPA has determined that reliable data show the 
safety of infants and children would be adequately protected if the 
FQPA SF were reduced to 1X. That decision is based on the following 
findings:
    i. The toxicity database for benzyl acetate contains the following 
studies that are adequate to evaluate the potential toxicity of benzyl 
acetate for infants and children: A thirteen week feeding study in the 
rat, a 13-week feeding study in the mouse, a developmental toxicity 
study in the rat, several in vivo and in vitro mutagenicity studies, 
and carcinogenicity studies in mice and rats via gavage and dietary 
studies.
    ii. Evidence of neurotoxicity and neuronal degeneration seen in a 
thirteen-week study was determined not to exceed levels of concern 
since the effects occurred at doses that were well above the limit dose 
(1,000 mg/kg/day). The established cRfD is 1.10 mg/kg/day therefore is 
protective of these effects.
    iii. Qualitative fetal susceptibility was observed in the 
developmental study in rats. Maternal (decrease in body weight) and 
fetal (reduced body weights, increased incidence of dilation of the 
renal pelvis and skeletal variations) toxicity were observed at 1,000 
mg/kg/day, the limit dose. Since fetal toxicity occurs in the presence 
of maternal toxicity and a clear NOAEL of 500 mg/kg/day was 
established, the established cRfD (1.10 mg/kg/day) will be protective 
of these effects. The potential for reproduction toxicity was observed 
in the 13-week dietary study in rats. Atrophy of seminiferous tubules 
was observed in males at 12,500 ppm (900 mg/kg/day). However, the 
concern for reproductive toxicity is low since effects occurred at a 
high dose and a clear NOAEL of 6,250 ppm (460 mg/kg/day) was 
established.
    iv. There are no residual uncertainties identified in the exposure 
databases. The dietary food exposure assessments were performed based 
on 100% CT and tolerance-level residues. EPA made conservative 
(protective) assumptions in the ground and surface water modeling used 
to assess exposure to benzyl acetate in drinking water. EPA used 
similarly conservative assumptions to assess post-application exposure 
of children as well as incidental oral exposure of toddlers. These 
assessments will not underestimate the exposure and risks posed by 
benzyl acetate.

E. Aggregate Risks and Determination of Safety Section

    EPA determines whether acute and chronic dietary pesticide 
exposures are safe by comparing aggregate exposure estimates to the 
acute PAD (aPAD) and chronic PAD (cPAD). For linear cancer risks, EPA 
calculates the lifetime probability of acquiring cancer given the 
estimated aggregate exposure. Short-, intermediate-, and chronic-term 
risks are evaluated by comparing the estimated aggregate food, water, 
and residential exposure to the appropriate PODs to ensure that an 
adequate MOE exists.
    1. Acute risk. An acute aggregate risk assessment takes into 
account acute exposure estimates from dietary consumption of food and 
drinking water. No adverse effect resulting from a single oral exposure 
was identified and no acute dietary endpoint was selected. Therefore, 
benzyl acetate is not expected to pose an acute risk.
    2. Chronic risk. Using the exposure assumptions described in this 
unit for chronic exposure, EPA has concluded that chronic exposure to 
benzyl acetate from food and water will utilize 62.9% of the cPAD for 
children ages 1 to 2, the population group receiving the greatest 
exposure.
    3. Short-term risk. Short-term aggregate exposure takes into 
account short-term residential exposure plus chronic exposure to food 
and water (considered to be a background exposure level).
    Benzyl acetate is likely to be used as an inert ingredient in 
pesticide products that are registered for uses that could result in 
short-term residential exposure, and the Agency has determined that it 
is appropriate to aggregate chronic exposure through food and water 
with short-term residential exposures to benzyl acetate. Using the 
exposure assumptions described in this unit for screening-level short-
term exposures, EPA has concluded the combined short-term food, water, 
and residential exposures result in aggregate MOEs of 150 for children 
ages 1 to 2 and 260 for adults. Because EPA's level of concern for 
benzyl acetate is a MOE of 100 or below, these MOEs are not of concern.
    4. Intermediate-term risk. Intermediate-term aggregate exposure 
takes into account intermediate-term residential exposure plus chronic 
exposure to food and water (considered to be a background exposure 
level). Because no intermediate-term adverse effect was identified, 
benzyl acetate is not expected to pose an intermediate-term risk.
    5. Aggregate cancer risk for U.S. population. Based on the lack of 
evidence of carcinogenicity in the dietary carcinogenicity studies in 
mice and rats, benzyl acetate is not expected to pose a cancer risk to 
humans.
    6. Determination of safety. Based on these risk assessments, 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 benzyl acetate residues.

V. Analytical Enforcement Methodology

    An analytical method is not required for enforcement purposes since 
the

[[Page 7477]]

Agency is establishing an exemption from the requirement of a tolerance 
without any numerical limitation.

VI. Conclusions

    Therefore, an exemption from the requirement of a tolerance is 
established under 40 CFR 180.920 for benzyl aceetate (CAS Reg. No. 140-
11-4) when used as an inert ingredient (solvent) in pesticide 
formulations applied to growing crops only.

VII. Statutory and Executive Order Reviews

    This action 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 action has been exempted from review 
under Executive Order 12866, this action 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 action 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 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 action 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 action. In addition, this 
action does not impose any enforceable duty or contain any unfunded 
mandate as described under Title II of the Unfunded Mandates Reform Act 
(UMRA) (2 U.S.C. 1501 et seq.).
    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 (NTTAA) (15 U.S.C. 272 note).

VIII. 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).
