Petition for Tolerance In the Federal Register of April 8, 2009 (74 FR 15971) (FRL–8407–4), EPA issued a notice pursuant to section 408(d)(3) of FFDCA, 21 U.S.C. 346a(d)(3), announcing the filing of a pesticide petition (PP 8E7492) by IR-4, IR-4 Project Headquarters, 500 College Rd. East, Suite 201 W., Princeton, NJ 08540. The petition requested that 40 CFR 180.510 be amended by establishing tolerances for residues of the insecticide pyriproxyfen in or on artichoke, globe at 2.0 parts per million (ppm); asparagus at 2.0 ppm; fruit, small, vine climbing subgroup, except grape 13–07E at 0.35 ppm; vegetable, foliage of legume, group 7 at 2.0 ppm; vegetable, leafy, except brassica, group 4 at 3.0 ppm; vegetable, leaves of root and tuber, group 2 at 2.0 ppm; and watercress at 2.0 ppm. That notice referenced a summary of the petition prepared by Valent U.S.A. Corporation, the registrant, on behalf of IR-4 which is available to the public in the docket, https://www.regulations.gov. There were no comments received in response to the notice of filing. III. Aggregate Risk Assessment and Determination of Safety Section 408(b)(2)(A)(i) of FFDCA allows EPA to establish 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 VerDate Nov<24>2008 14:04 Oct 27, 2009 Jkt 220001 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....’’ Consistent with section 408(b)(2)(D) of FFDCA, and the factors specified in section 408(b)(2)(D) of FFDCA, 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 the petitioned-for tolerances for residues of pyriproxyfen in or on vegetable, leaves of root and tuber, group 2 at 2.0 ppm; vegetable, leafy, except brassica, group 4 at 3.0 ppm; vegetable, foliage of legume, group 7 at 2.0 ppm; artichoke, globe at 2.0 ppm; asparagus at 2.0 ppm; watercress at 2.0 ppm; and small fruit vine climbing subgroup, except grape 13–07E at 0.35 ppm ppm. EPA’s assessment of exposures and risks associated with establishing tolerances follows. A. Toxicological Profile EPA has evaluated the available toxicity data and considered its 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. Pyriproxyfen is of low acute toxicity. Pyriproxyfen is not a dermal sensitizer. No significant systemic toxicity was observed in either the 21–day dermal toxicity study in rats or the 28–day inhalation toxicity study in rats. Subchronic and chronic toxicity studies in mice, rats and dogs indicate that the liver and kidney are the principal target organs with slight anemia occurring in the rodent species. There was no evidence of increased susceptibility to rat and rabbit fetuses in prenatal developmental toxicity studies or to rat offspring in the 2–generation rat reproduction study. No evidence of developmental toxicity was seen in special studies that evaluated pyriproxyfen toxicity following perinatal and prenatal exposure in rats. There was no evidence of carcinogenicity in either a 78–week mouse feeding study or in the 2–year rat chronic/carcinogenicity study. Pyriproxyfen is classified as a ‘‘Group E’’ chemical - no evidence of carcinogenicity to humans. Pyriproxyfen is negative for mutagenic activity in a battery of mutagenicity PO 00000 Frm 00024 Fmt 4700 Sfmt 4700 studies conducted with both the parent and/or metabolites. Specific information on the studies received and the nature of the adverse effects caused by pyriproxyfen as well as the no-observedadverse-effect-level (NOAEL) and the lowest-observed-adverse-effect-level (LOAEL) from the toxicity studies can be found at https://www.regulations.gov in docket ID number EPA–HQ–OPP– 2009–0018 on pages 34–36 of the document titled ‘‘Pyriproxyfen. Human Health Risk Assessment for the Proposed Use of Pyriproxyfen in/on Vegetables, Leaves of Root and Tuber, Group 2; Vegetables, Leafy, Except Brassica, Group 4; Vegetable, Foliage of Legume, Group 7; Fruit, Small, Vine Climbing, Except Grape, Subgroup 13– 07E; Artichoke, Globe; Asparagus; and Watercress Commodities.’’ B. Toxicological Endpoints For hazards that have a threshold below which there is no appreciable risk, a toxicological point of departure (POD) is identified as the basis for derivation of reference values for risk assessment. The POD may be defined as the highest dose at which no adverse effects are observed (the NOAEL) in the toxicology study identified as appropriate for use in risk assessment. However, if a NOAEL cannot be determined, the lowest dose at which adverse effects of concern are identified (the LOAEL) or a Benchmark Dose (BMD) approach is sometimes used for risk assessment. Uncertainty/safety factors (UFs) are used in conjunction with the POD to take into account uncertainties inherent in the extrapolation from laboratory animal data to humans and in the variations in sensitivity among members of the human population as well as other unknowns. Safety is assessed for acute and chronic dietary risks by comparing aggregate food and water exposure to the pesticide to the acute population adjusted dose (aPAD) and chronic population adjusted dose (cPAD). The aPAD and cPAD are calculated by dividing the POD by all applicable UFs. Aggregate short-term, intermediate-term, and chronic-term risks are evaluated by comparing food, water, and residential exposure to the POD to ensure that the margin of exposure (MOE) called for by the product of all applicable UFs is not exceeded. This latter value is referred to as the Level of Concern (LOC). 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 greater than that expected in a lifetime.

A summary of the toxicological endpoints for pyriproxyfen used for human risk assessment can be found at https://www.regulations.gov in docket ID number EPA–HQ–OPP–2009–0018 on pages 16–18 of the document titled ‘‘Pyriproxyfen.

Exposure Assessment 1. Dietary exposure from food and feed uses. In evaluating dietary exposure to pyriproxyfen, EPA considered exposure under the petitioned-for tolerances as well as all existing pyriproxyfen tolerances in 40 CFR 180.510. EPA assessed dietary exposures from pyriproxyfen in food as follows: i. Acute exposure. Quantitative acute dietary exposure and risk assessments are performed for a food-use pesticide, if a toxicological study has indicated the possibility of an effect of concern occurring as a result of a 1–day or single exposure. No such effects were identified in the toxicological studies for pyriproxyfen; therefore, a quantitative acute dietary exposure assessment is unnecessary. ii. Chronic exposure. In conducting the chronic dietary exposure assessment EPA used the food consumption data from the U.S. Department of Agriculture (USDA) 1994–1996 and 1998 Continuing Survey of Food Intake by Individuals (CSFII). As to residue levels in food, EPA performed an unrefined chronic analysis which assumed 100% crop treated (CT), default processing factors, and tolerance level residues for all commodities. iii. Cancer. Based on the absence of evidence of carcinogenicity in two adequate rodent carcinogenicity studies, EPA has classified pyriproxyfen as ‘‘not likely to be carcinogenic to humans.’’ Therefore, a quantitative exposure assessment to evaluate cancer risk is unnecessary. iv. Anticipated residue and percent crop treated (PCT) information. As noted above in Unit III.C.1.ii., EPA did not use anticipated residue and/or PCT information in the dietary assessment for pyriproxyfen. Tolerance level VerDate Nov<24>2008 14:04 Oct 27, 2009 Jkt 220001 residues and/or 100% CT were assumed for all food commodities. 2. Dietary exposure from drinking water. The Agency used screening level water exposure models in the dietary exposure analysis and risk assessment for pyriproxyfen in drinking water. These simulation models take into account data on the physical, chemical, and fate/transport characteristics of pyriproxyfen. Further information regarding EPA drinking water models used in pesticide exposure assessment can be found at https://www.epa.gov/ oppefed1/models/water/index.htm. Based on the Pesticide Root Zone Model/Exposure Analysis Modeling System (PRZM/EXAMS) and Screening Concentration in Ground Water (SCIGROW) models, the estimated drinking water concentrations (EDWCs) of pyriproxyfen for chronic exposures for non-cancer assessments are estimated to be 0.52 parts per billion (ppb) for surface water and 0.0022 ppb for ground water. Modeled estimates of drinking water concentrations were directly entered into the dietary exposure model. For chronic dietary risk assessment, the water concentration of value 0.52 ppb was used to assess the contribution to drinking water. 3. From non-dietary exposure. The term ‘‘residential exposure’’ is used in this document to refer to nonoccupational, non-dietary exposure (e.g., for lawn and garden pest control, indoor pest control, termiticides, and flea and tick control on pets). Pyriproxyfen is the active ingredient in many registered residential products for flea and tick control (home environment and pet treatments) as well as products for ant and roach control (indoor and outdoor applications). Formulations include carpet powders, foggers, aerosol sprays, liquids (shampoos, sprays and pipettes for pet treatments), granules, bait (indoor and outdoor), and impregnated materials (pet collars). Only a post-application residential assessment was conducted as the Agency did not select any short-term dermal or inhalation endpoints. Toddlers are anticipated to have the highest exposures from treated home environments and pets due to typical hand-to-mouth behavior. EPA assessed residential exposure using the following assumptions: • Short-term, intermediate-term, and long-term toddler hand-to-mouth exposures (consisting of petting treated animals and touching treated carpets/ flooring). • Long-term dermal exposures for products with anticipated efficacy more PO 00000 Frm 00025 Fmt 4700 Sfmt 4700 55465 than 6 months (carpet powders and pet collars). • Combined treatment toddler exposure scenarios as a result of treatments to the home environment and the pet in the same period (such as carpet powder and pet shampoo treatments). Episodic ingestion of granules by toddlers is anticipated, but an assessment for this scenario is not included, since an acute dietary endpoint was not selected. 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 pyriproxyfen to share a common mechanism of toxicity with any other substances, and pyriproxyfen does not appear to produce a toxic metabolite produced by other substances. For the purposes of this tolerance action, therefore, EPA has assumed that pyriproxyfen 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 website 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 Food Quality Protection Act Safety Factor (FQPA SF). In applying this provision, EPA either retains the default value of 10X, or uses a different additional SF when reliable data available to EPA support the choice of a different factor. 2. Prenatal and postnatal sensitivity. Based on the available data, there is no quantitative and qualitative evidence of increased susceptibility observed following in utero pyriproxyfen exposure to rats and rabbits or following prenatal/postnatal exposure in the 2– generation reproduction study. E:\FR\FM\28OCR1.SGM 28OCR1 erowe on DSK5CLS3C1PROD with RULES 55466 Federal Register / Vol. 74, No. 207 / Wednesday, October 28, 2009 / Rules and Regulations 3. Conclusion. EPA has determined that reliable data show that it would be safe for infants and children to reduce the FQPA SF to 1X. That decision is based on the following findings: i. The toxicity database for pyriproxyfen is complete except for acute and subchronic neurotoxicity studies and immunotoxicity testing. Recent changes to 40 CFR part 158 make these studies (OPPTS Guideline 870.7800) required for pesticide registration; however, the available data for pyriproxyfen do not show potential for neurotoxicity or immunotoxicity. Although neurotoxicity studies have not yet been submitted, there is no evidence of neurotoxicity in any study in the toxicity database for pyriproxyfen. Similarly, although the database contains no specific immunotoxicity studies, no evidence of immunotoxicity was found in existing studies. EPA does not believe that conducting immunotoxicity testing will result in a NOAEL less than the chronic Referenced Dose (cRfD) NOAEL of 35.1 milligrams/kilogram body weight/day (mg/kg bw/day) already established for pyriproxyfen or that acute or subchronic neurotoxicity studies would affect selection of the acute Referenced Dose (aRfD) or cRfD. Accordingly, EPA concludes that an additional factor for database uncertainties is not needed to account for potential immunotoxicity or neurotoxicity. ii. There is no indication that pyriproxyfen is a neurotoxic chemical and there is no need for a developmental neurotoxicity study or additional uncertainty factors (UF) to account for neurotoxicity. iii. There is no evidence that pyriproxyfen results in increased susceptibility in utero in rats or rabbits in the prenatal developmental studies or in young rats in the 2–generation reproduction study. 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. Conservative ground water and surface water modeling estimates were used. Similarly, conservative Residential Standard Operating Procedues (SOPs) were used to assess post-application exposure to children as well as incidental oral exposure of toddlers. These assessments will not underestimate the exposure and risks posed by pyriproxyfen. E. Aggregate Risks and Determination of Safety EPA determines whether acute and chronic pesticide exposures are safe by VerDate Nov<24>2008 14:04 Oct 27, 2009 Jkt 220001 comparing aggregate exposure estimates to the aPAD and cPAD. The aPAD and cPAD represent the highest safe exposures, taking into account all appropriate SFs. EPA calculates the aPAD and cPAD by dividing the POD by all applicable UFs. For linear cancer risks, EPA calculates the probability of additional cancer cases given the estimated aggregate exposure. Shortterm, intermediate-term, and chronicterm risks are evaluated by comparing the estimated aggregate food, water, and residential exposure to the POD to ensure that the MOE called for by the product of all applicable UFs is not exceeded. 1. Acute risk. An acute aggregate risk assessment takes into account exposure estimates from acute 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, pyriproxyfen 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 pyriproxyfen from food and water will utilize 10% of the cPAD for children 1 to 2 years old, the population group receiving the greatest exposure. A long-term postapplication residential assessment was performed. Toddlers are anticipated to have higher exposures than adults from treated home environments and pets due to their behavior patterns. The total chronic dietary and residential aggregate MOEs range from 580 to 4,500. For pyriproxifen, EPA would be concerned if the MOE was below 100. 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). Pyriproxyfen is currently 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 pyriproxyfen. Using the exposure assumptions described in this unit for short-term exposures, EPA has concluded the combined short-term food, water, and residential exposures aggregated result in aggregate MOEs of 1,200 for children 1 to 2 years old, the population group receiving the greatest exposure, and therefore is not a concern. 4. Intermediate-term risk. Intermediate-term aggregate exposure takes into account intermediate-term residential exposure plus chronic PO 00000 Frm 00026 Fmt 4700 Sfmt 4700 exposure to food and water (considered to be a background exposure level). Pyriproxyfen is currently registered for uses that could result in intermediate-term residential exposure and the Agency has determined that it is appropriate to aggregate chronic exposure to pyriproxyfen through food and water with intermediate-term exposures for pyriproxyfen. Using the exposure assumptions described in this unit for intermediateterm exposures, EPA has concluded that the combined intermediate-term food, water, and residential exposures aggregated result in aggregate MOEs of 430 for children 1 to 2 years old, the population group receiving the greatest exposure, and therefore is not a concern. 5. Aggregate cancer risk for U.S. population. Pyriproxyfen is classified as a ‘‘Group E’’ chemical (negative for carcinogenicity in humans). This classification is based on the lack of evidence of carcinogenicity in mice and rats. EPA does not expect pyriproxyfen to pose a cancer risk. 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 pyriproxyfen residues. IV. Other Considerations A. Analytical Enforcement Methodology Adequate enforcement methodology (gas chromatography/nitrogenphosphorous detector; GC/NPD) is available to enforce the tolerance expression. The method may be requested from: Chief, Analytical Chemistry Branch, Environmental Science Center, 701 Mapes Rd., Ft. Meade, MD 20755–5350; telephone number: (410) 305–2905; e-mail address: residuemethods@epa.gov. B. International Residue Limits There are currently no established Codex maximum residue limits for pyriproxyfen. V. Conclusion Therefore, tolerances are established for residues of pyriproxyfen in or on artichoke, globe at 2.0 ppm; asparagus at 2.0 ppm; fruit, small, vine climbing subgroup, except grape 13–07E at 0.35 ppm; vegetable, foliage of legume, group 7 at 2.0 ppm; vegetable, leafy, except brassica, group 4 at 3.0 ppm; vegetable, leaves of root and tuber, group 2 at 2.0 ppm; and watercress at 2.0 ppm.

Statutory and Executive Order Reviews This final rule establishes tolerances under section 408(d) of FFDCA in response to a petition submitted to the Agency. The Office of Management and Budget (OMB) has exempted these types of actions from review under Executive Order 12866, entitled Regulatory Planning and Review (58 FR 51735, October 4, 1993). Because this 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 section 408(d) of FFDCA, 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 section 408(n)(4) of FFDCA. 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 VerDate Nov<24>2008 14:04 Oct 27, 2009 Jkt 220001 Unfunded Mandates Reform Act of 1995 (UMRA) (Public Law 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). VII. 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).

II. Petition for Tolerance

    In the Federal Register of April 8, 2009 (74 FR 15971) (FRL-8407-
4), EPA issued a notice pursuant to section 408(d)(3) of FFDCA, 21 
U.S.C. 346a(d)(3), announcing the filing of a pesticide petition (PP 
8E7492) by IR-4, IR-4 Project Headquarters, 500 College Rd. East, Suite 
201 W., Princeton, NJ 08540. The petition requested that 40 CFR 180.510 
be amended by establishing tolerances for residues of the insecticide 
pyriproxyfen in or on artichoke, globe at 2.0 parts per million (ppm); 
asparagus at 2.0 ppm; fruit, small, vine climbing subgroup, except 
grape 13-07E at 0.35 ppm; vegetable, foliage of legume, group 7 at 2.0 
ppm; vegetable, leafy, except brassica, group 4 at 3.0 ppm; vegetable, 
leaves of root and tuber, group 2 at 2.0 ppm; and watercress at 2.0 
ppm. That notice referenced a summary of the petition prepared by 
Valent U.S.A. Corporation, the registrant, on behalf of IR-4 which is 
available to the public in the docket, https://www.regulations.gov. 
There were no comments received in response to the notice of filing.

III. Aggregate Risk Assessment and Determination of Safety

    Section 408(b)(2)(A)(i) of FFDCA allows EPA to establish 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....''
    Consistent with section 408(b)(2)(D) of FFDCA, and the factors 
specified in section 408(b)(2)(D) of FFDCA, 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 the petitioned-for 
tolerances for residues of pyriproxyfen in or on vegetable, leaves of 
root and tuber, group 2 at 2.0 ppm; vegetable, leafy, except brassica, 
group 4 at 3.0 ppm; vegetable, foliage of legume, group 7 at 2.0 ppm; 
artichoke, globe at 2.0 ppm; asparagus at 2.0 ppm; watercress at 2.0 
ppm; and small fruit vine climbing subgroup, except grape 13-07E at 
0.35 ppm ppm. EPA's assessment of exposures and risks associated with 
establishing tolerances follows.

A. Toxicological Profile

    EPA has evaluated the available toxicity data and considered its 
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.
    Pyriproxyfen is of low acute toxicity. Pyriproxyfen is not a dermal 
sensitizer. No significant systemic toxicity was observed in either the 
21-day dermal toxicity study in rats or the 28-day inhalation toxicity 
study in rats. Subchronic and chronic toxicity studies in mice, rats 
and dogs indicate that the liver and kidney are the principal target 
organs with slight anemia occurring in the rodent species. There was no 
evidence of increased susceptibility to rat and rabbit fetuses in 
prenatal developmental toxicity studies or to rat offspring in the 2-
generation rat reproduction study. No evidence of developmental 
toxicity was seen in special studies that evaluated pyriproxyfen 
toxicity following perinatal and prenatal exposure in rats. There was 
no evidence of carcinogenicity in either a 78-week mouse feeding study 
or in the 2-year rat chronic/carcinogenicity study. Pyriproxyfen is 
classified as a ``Group E'' chemical - no evidence of carcinogenicity 
to humans. Pyriproxyfen is negative for mutagenic activity in a battery 
of mutagenicity studies conducted with both the parent and/or 
metabolites. Specific information on the studies received and the 
nature of the adverse effects caused by pyriproxyfen as well as the no-
observed-adverse-effect-level (NOAEL) and the lowest-observed-adverse-
effect-level (LOAEL) from the toxicity studies can be found at https://www.regulations.gov in docket ID number EPA-HQ-OPP-2009-0018 on pages 
34-36 of the document titled ``Pyriproxyfen. Human Health Risk 
Assessment for the Proposed Use of Pyriproxyfen in/on Vegetables, 
Leaves of Root and Tuber, Group 2; Vegetables, Leafy, Except Brassica, 
Group 4; Vegetable, Foliage of Legume, Group 7; Fruit, Small, Vine 
Climbing, Except Grape, Subgroup 13-07E; Artichoke, Globe; Asparagus; 
and Watercress Commodities.''

B. Toxicological Endpoints

    For hazards that have a threshold below which there is no 
appreciable risk, a toxicological point of departure (POD) is 
identified as the basis for derivation of reference values for risk 
assessment. The POD may be defined as the highest dose at which no 
adverse effects are observed (the NOAEL) in the toxicology study 
identified as appropriate for use in risk assessment. However, if a 
NOAEL cannot be determined, the lowest dose at which adverse effects of 
concern are identified (the LOAEL) or a Benchmark Dose (BMD) approach 
is sometimes used for risk assessment. Uncertainty/safety factors (UFs) 
are used in conjunction with the POD to take into account uncertainties 
inherent in the extrapolation from laboratory animal data to humans and 
in the variations in sensitivity among members of the human population 
as well as other unknowns. Safety is assessed for acute and chronic 
dietary risks by comparing aggregate food and water exposure to the 
pesticide to the acute population adjusted dose (aPAD) and chronic 
population adjusted dose (cPAD). The aPAD and cPAD are calculated by 
dividing the POD by all applicable UFs. Aggregate short-term, 
intermediate-term, and chronic-term risks are evaluated by comparing 
food, water, and residential exposure to the POD to ensure that the 
margin of exposure (MOE) called for by the product of all applicable 
UFs is not exceeded. This latter value is referred to as the Level of 
Concern (LOC).
    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 
greater than that expected in a lifetime. For more information on

description of the risk assessment process, see https://www.epa.gov/pesticides/factsheets/riskassess.htm.
    A summary of the toxicological endpoints for pyriproxyfen used for 
human risk assessment can be found at https://www.regulations.gov in 
docket ID number EPA-HQ-OPP-2009-0018 on pages 16-18 of the document 
titled ``Pyriproxyfen. Human Health Risk Assessment for the Proposed 
Use of Pyriproxyfen in/on Vegetables, Leaves of Root and Tuber, Group 
2; Vegetables, Leafy, Except Brassica, Group 4; Vegetable, Foliage of 
Legume, Group 7; Fruit, Small, Vine Climbing, Except Grape, Subgroup 
13-07E; Artichoke, Globe; Asparagus; and Watercress Commodities.''

C. Exposure Assessment

    1. Dietary exposure from food and feed uses. In evaluating dietary 
exposure to pyriproxyfen, EPA considered exposure under the petitioned-
for tolerances as well as all existing pyriproxyfen tolerances in 40 
CFR 180.510. EPA assessed dietary exposures from pyriproxyfen in food 
as follows:
    i. Acute exposure. Quantitative acute dietary exposure and risk 
assessments are performed for a food-use pesticide, if a toxicological 
study has indicated the possibility of an effect of concern occurring 
as a result of a 1-day or single exposure. No such effects were 
identified in the toxicological studies for pyriproxyfen; therefore, a 
quantitative acute dietary exposure assessment is unnecessary.
    ii. Chronic exposure. In conducting the chronic dietary exposure 
assessment EPA used the food consumption data from the U.S. Department 
of Agriculture (USDA) 1994-1996 and 1998 Continuing Survey of Food 
Intake by Individuals (CSFII). As to residue levels in food, EPA 
performed an unrefined chronic analysis which assumed 100% crop treated 
(CT), default processing factors, and tolerance level residues for all 
commodities.
    iii. Cancer. Based on the absence of evidence of carcinogenicity in 
two adequate rodent carcinogenicity studies, EPA has classified 
pyriproxyfen as ``not likely to be carcinogenic to humans.'' Therefore, 
a quantitative exposure assessment to evaluate cancer risk is 
unnecessary.
    iv. Anticipated residue and percent crop treated (PCT) information. 
As noted above in Unit III.C.1.ii., EPA did not use anticipated residue 
and/or PCT information in the dietary assessment for pyriproxyfen. 
Tolerance level residues and/or 100% CT were assumed for all food 
commodities.
    2. Dietary exposure from drinking water. The Agency used screening 
level water exposure models in the dietary exposure analysis and risk 
assessment for pyriproxyfen in drinking water. These simulation models 
take into account data on the physical, chemical, and fate/transport 
characteristics of pyriproxyfen. Further information regarding EPA 
drinking water models used in pesticide exposure assessment can be 
found at https://www.epa.gov/oppefed1/models/water/index.htm.
    Based on the Pesticide Root Zone Model/Exposure Analysis Modeling 
System (PRZM/EXAMS) and Screening Concentration in Ground Water (SCI-
GROW) models, the estimated drinking water concentrations (EDWCs) of 
pyriproxyfen for chronic exposures for non-cancer assessments are 
estimated to be 0.52 parts per billion (ppb) for surface water and 
0.0022 ppb for ground water.
    Modeled estimates of drinking water concentrations were directly 
entered into the dietary exposure model. For chronic dietary risk 
assessment, the water concentration of value 0.52 ppb was used to 
assess the contribution to drinking water.
    3. From non-dietary exposure. The term ``residential exposure'' is 
used in this document to refer to non-occupational, non-dietary 
exposure (e.g., for lawn and garden pest control, indoor pest control, 
termiticides, and flea and tick control on pets).
    Pyriproxyfen is the active ingredient in many registered 
residential products for flea and tick control (home environment and 
pet treatments) as well as products for ant and roach control (indoor 
and outdoor applications). Formulations include carpet powders, 
foggers, aerosol sprays, liquids (shampoos, sprays and pipettes for pet 
treatments), granules, bait (indoor and outdoor), and impregnated 
materials (pet collars). Only a post-application residential assessment 
was conducted as the Agency did not select any short-term dermal or 
inhalation endpoints. Toddlers are anticipated to have the highest 
exposures from treated home environments and pets due to typical hand-
to-mouth behavior. EPA assessed residential exposure using the 
following assumptions:
     Short-term, intermediate-term, and long-term toddler hand-
to-mouth exposures (consisting of petting treated animals and touching 
treated carpets/flooring).
     Long-term dermal exposures for products with anticipated 
efficacy more than 6 months (carpet powders and pet collars).
     Combined treatment toddler exposure scenarios as a result 
of treatments to the home environment and the pet in the same period 
(such as carpet powder and pet shampoo treatments). Episodic ingestion 
of granules by toddlers is anticipated, but an assessment for this 
scenario is not included, since an acute dietary endpoint was not 
selected.
    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 pyriproxyfen to share a common mechanism of 
toxicity with any other substances, and pyriproxyfen does not appear to 
produce a toxic metabolite produced by other substances. For the 
purposes of this tolerance action, therefore, EPA has assumed that 
pyriproxyfen 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 website 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 Food Quality 
Protection Act Safety Factor (FQPA SF). In applying this provision, EPA 
either retains the default value of 10X, or uses a different additional 
SF when reliable data available to EPA support the choice of a 
different factor.
    2. Prenatal and postnatal sensitivity. Based on the available data, 
there is no quantitative and qualitative evidence of increased 
susceptibility observed following in utero pyriproxyfen exposure to 
rats and rabbits or following prenatal/postnatal exposure in the 2-
generation reproduction study.

[[Page 55466]]

    3. Conclusion. EPA has determined that reliable data show that it 
would be safe for infants and children to reduce the FQPA SF to 1X. 
That decision is based on the following findings:
    i. The toxicity database for pyriproxyfen is complete except for 
acute and subchronic neurotoxicity studies and immunotoxicity testing. 
Recent changes to 40 CFR part 158 make these studies (OPPTS Guideline 
870.7800) required for pesticide registration; however, the available 
data for pyriproxyfen do not show potential for neurotoxicity or 
immunotoxicity. Although neurotoxicity studies have not yet been 
submitted, there is no evidence of neurotoxicity in any study in the 
toxicity database for pyriproxyfen. Similarly, although the database 
contains no specific immunotoxicity studies, no evidence of 
immunotoxicity was found in existing studies. EPA does not believe that 
conducting immunotoxicity testing will result in a NOAEL less than the 
chronic Referenced Dose (cRfD) NOAEL of 35.1 milligrams/kilogram body 
weight/day (mg/kg bw/day) already established for pyriproxyfen or that 
acute or subchronic neurotoxicity studies would affect selection of the 
acute Referenced Dose (aRfD) or cRfD. Accordingly, EPA concludes that 
an additional factor for database uncertainties is not needed to 
account for potential immunotoxicity or neurotoxicity.
    ii. There is no indication that pyriproxyfen is a neurotoxic 
chemical and there is no need for a developmental neurotoxicity study 
or additional uncertainty factors (UF) to account for neurotoxicity.
    iii. There is no evidence that pyriproxyfen results in increased 
susceptibility in utero in rats or rabbits in the prenatal 
developmental studies or in young rats in the 2-generation reproduction 
study.
    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. Conservative ground water and 
surface water modeling estimates were used. Similarly, conservative 
Residential Standard Operating Procedues (SOPs) were used to assess 
post-application exposure to children as well as incidental oral 
exposure of toddlers. These assessments will not underestimate the 
exposure and risks posed by pyriproxyfen.

E. Aggregate Risks and Determination of Safety

    EPA determines whether acute and chronic pesticide exposures are 
safe by comparing aggregate exposure estimates to the aPAD and cPAD. 
The aPAD and cPAD represent the highest safe exposures, taking into 
account all appropriate SFs. EPA calculates the aPAD and cPAD by 
dividing the POD by all applicable UFs. For linear cancer risks, EPA 
calculates the probability of additional cancer cases given the 
estimated aggregate exposure. Short-term, intermediate-term, and 
chronic-term risks are evaluated by comparing the estimated aggregate 
food, water, and residential exposure to the POD to ensure that the MOE 
called for by the product of all applicable UFs is not exceeded.
    1. Acute risk. An acute aggregate risk assessment takes into 
account exposure estimates from acute 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, 
pyriproxyfen 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 
pyriproxyfen from food and water will utilize 10% of the cPAD for 
children 1 to 2 years old, the population group receiving the greatest 
exposure. A long-term post-application residential assessment was 
performed. Toddlers are anticipated to have higher exposures than 
adults from treated home environments and pets due to their behavior 
patterns. The total chronic dietary and residential aggregate MOEs 
range from 580 to 4,500. For pyriproxifen, EPA would be concerned if 
the MOE was below 100.
    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).
    Pyriproxyfen is currently 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 pyriproxyfen.
    Using the exposure assumptions described in this unit for short-
term exposures, EPA has concluded the combined short-term food, water, 
and residential exposures aggregated result in aggregate MOEs of 1,200 
for children 1 to 2 years old, the population group receiving the 
greatest exposure, and therefore is not a 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).
    Pyriproxyfen is currently registered for uses that could result in 
intermediate-term residential exposure and the Agency has determined 
that it is appropriate to aggregate chronic exposure to pyriproxyfen 
through food and water with intermediate-term exposures for 
pyriproxyfen.
    Using the exposure assumptions described in this unit for 
intermediate-term exposures, EPA has concluded that the combined 
intermediate-term food, water, and residential exposures aggregated 
result in aggregate MOEs of 430 for children 1 to 2 years old, the 
population group receiving the greatest exposure, and therefore is not 
a concern.
    5. Aggregate cancer risk for U.S. population. Pyriproxyfen is 
classified as a ``Group E'' chemical (negative for carcinogenicity in 
humans). This classification is based on the lack of evidence of 
carcinogenicity in mice and rats. EPA does not expect pyriproxyfen to 
pose a cancer risk.
    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 pyriproxyfen residues.

IV. Other Considerations

A. Analytical Enforcement Methodology

    Adequate enforcement methodology (gas chromatography/nitrogen-
phosphorous detector; GC/NPD) is available to enforce the tolerance 
expression. The method may be requested from: Chief, Analytical 
Chemistry Branch, Environmental Science Center, 701 Mapes Rd., Ft. 
Meade, MD 20755-5350; telephone number: (410) 305-2905; e-mail address: 
residuemethods@epa.gov.

B. International Residue Limits

    There are currently no established Codex maximum residue limits for 
pyriproxyfen.

V. Conclusion

    Therefore, tolerances are established for residues of pyriproxyfen

VI. Statutory and Executive Order Reviews

    This final rule establishes tolerances under section 408(d) of 
FFDCA in response to a petition submitted to the Agency. The Office of 
Management and Budget (OMB) has exempted these types of actions from 
review under Executive Order 12866, entitled Regulatory Planning and 
Review (58 FR 51735, October 4, 1993). Because this 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 section 408(d) of FFDCA, 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 section 408(n)(4) of FFDCA. 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) (Public Law 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).

VII. 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).
