1Technical Support Document for the Final Clean Air Interstate Rule: Air Quality Modeling ( Docket No. OAR 2003 0053 2151).

2Clean Air Interstate Rule Emissions Inventory Technical Support Document ( Docket No. OAR 2003 0053 2047).

3Contents of CAIR Updated Modeling Platform Disk Drive ( Docket No. OAR 2003 1688). Disk Drive Containing Emissions Input Data Sets and Model Outputs for the CAIR Revised Modeling of the Contribution from Minnesota to PM2.5 Nonattainment in Downwind States Below is a listing of the modeling data from the revised Minnesota PM2.5 contribution modeling which EPA is providing on a disk drive in the Clean Air Interstate Rule ( CAIR docket). This revised analysis for Minnesota includes modeling using the CAIR PM2.5 air quality modeling platform as described in the CAIR air quality modeling technical support document1 and the emissions inventory technical support document2 coupled with updated future year 2010 emissions from utility sources in Minnesota. The updated 2010 utility emissions for Minnesota and the results of the revised modeling are described in the CAIR Notice of Reconsideration ( December 2005) .

The revised Minnesota PM2.5 modeling data are also available for download from the following ftp site: ftp:// www. airmodelingftp. com/ under the directory CAIR_ Petition_ Reconsideration_ Minnesota Please contact Peter Eckhoff: eckhoff. peter@ epa. gov for access to this ftp site.

The data disk drive includes the following data sets Emissions: model ready emissions input files ( one file per day containing hourly 3 dimensional gridded emissions) for each of three scenarios used in the revised Minnesota modeling ( 1) 2001 Base Year emissions ( 2001ad_ 2) ( 2) 2010 Base Case emissions ( 2010af_ 2) ( 3) 2010 Minnesota Zero Out emissions ( 2010af_ 2_ zMN)

Model Outputs: Two types of concentration output files from simulations of the Community Multiscale Air Quality Model ( CMAQ). ( 1) Hourly layer 1 gridded concentrations ( ACONC files) ( 2) Daily average layer 1 gridded concentration files ( dailyavg. aconc files)

Note that EPA runs annual simulations of CMAQ in 3 month ( i. e. quarterly) segments ( e. g., January, February, and March is the first segment of the year). There is a 10 day ramp up ( i. e., model initialization) period for each segment. The CMAQ outputs for the ramp up days are included on the disk drive but were not included in the PM2.5 contribution analysis. The emissions inputs for December 22  31, 2000, which is the ramp up period for the first quarterly model run, are also included on the disk drive.

The non emissions inputs ( e. g., meteorological inputs) which EPA used to run CMAQ for the revised Minnesota modeling are available on a separate disk drive in the CAIR docket3. These data can also be downloaded from the cair_ noda directory at the above air modeling ftp site.

In addition, EPA will provide, on request, copies of the CAIR modeling input and output files, model run scripts, and pre and post processing code on user provided disk drive( s). Please email Norm Possiel at possiel. norm@ epa. gov regarding any such requests.

The petition requested that 40 CFR 180.510 be amended by establishing a tolerance for residues of the insecticide, pyriproxyfen, 2[ 1 methyl 2( 4 phenoxyphenoxy) ethoxypyridine, in or on Brassica leafy vegetables ( Crop Group 5); vegetable, cucurbit ( Crop Group 9); olive and olive, oil at 2.5, 0.1, 1.0, and 3.0 parts per million ( ppm) respectively. Based on the residue data submitted, EPA has determined that the following changes to the requested tolerances listed in this document are necessary. A lower tolerance of 2.0 ppm is required for olive, oil. Brassica vegetables are devided into two subgroups. A tolerance of 0.70 is required for Brassica, head and stem, subgroup 5A. A tolerance of 2.0 ppm is required for Brassica, leafy greens, subgroup 5B. Section 408( b)( 2)( A)( i) of the 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 the 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 the 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 performs a number of analyses to determine the risks from aggregate exposure to pesticide residues. For further discussion of the regulatory requirements of section 408 of the FFDCA and a complete description of the risk assessment process, see the final rule on Bifenthrin Pesticide Tolerances ( 62 FR 62961, November 26, 1997) ( FRL   5754   7).

III. Aggregate Risk Assessment and Determination of Safety Consistent with section 408( b)( 2)( D) of the 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, consistent with section 408( b)( 2) of the FFDCA, for a tolerance for residues of pyriproxyfen on Brassica, head and stem, subgroup 5A; Brassica, leafy greens, subgroup 5B; Vegetable, cucurbit ( Group 9); olive and olive, oil at 0.70, 2.0, 0.10, 1.0, and 2.0 ppm, respectively. EPA's assessment of exposures and risks associated with establishing the tolerance 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. The nature of the toxic effects caused by pyriproxyfen are discussed in Table 1 of this unit as well as the no observed adverse effect level ( NOAEL) and the lowest observedadverse effect level ( LOAEL) from the toxicity studies reviewed.

Most radioactivity was excreted in the feces ( 81   92%) and urine ( 5   12%) over a 7 day collection period. Expired air containing CO2 was not detected. Tissue radioactivity levels were very low ( less than 0.3%) except for fat. Examination of urine, feces, liver, kidney, bile, and blood metabolites yielded numerous (> 20) identified metabolites when compared to synthetic standards. The major biotransformation reactions of pyriproxyfen include: 1. Oxidation of the 4'   position of the terminal phenyl group. 2. Oxidation at the 5'   position of pyridine. 3. Cleavage of the ether linkage and conjugation of the resultant phenols with sulfuric acid.

Toxicological Endpoints The dose at which no adverse effects are observed ( the NOAEL) from the toxicology study identified as appropriate for use in risk assessment is used to estimate the toxicological level of concern ( LOC). However, the lowest dose at which adverse effects of concern are identified ( the LOAEL) is sometimes used for risk assessment if no NOAEL was achieved in the toxicology study selected. An uncertainty factor ( UF) is applied to reflect 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. An UF of 100 is routinely used, 10X to account for interspecies differences and 10X for intra species differences. For dietary risk assessment ( other than cancer) the Agency uses the UF to calculate an acute or chronic reference dose ( acute RfD or chronic RfD) where the RfD is equal to the NOAEL divided by the appropriate UF ( RfD = NOAEL/ UF). Where an additional safety factors ( SF) is retained due to concerns unique to the FQPA, this additional factor is applied to the RfD by dividing the RfD by such additional factor. The acute or chronic Population Adjusted Dose ( aPAD or cPAD) is a modification of the RfD to accommodate this type of FQPA SF. For non dietary risk assessments ( other than cancer) the UF is used to determine the LOC. For example, when 100 is the appropriate UF ( 10X to account for interspecies differences and 10X for intraspecies differences) the LOC is 100. To estimate risk, a ratio of the NOAEL to exposures ( margin of exposure ( MOE) = NOAEL/ exposure) is calculated and compared to the LOC. A summary of the toxicological endpoints for pyriproxyfen used for human risk assessment is shown in Table 2 of this unit:

C. Exposure Assessment 1. Dietary exposure from food and feed uses. Tolerances have been established ( 40 CFR 180.510) for the residues of pyriproxyfen, in or on a variety of raw agricultural commodities. Risk assessments were conducted by EPA to assess dietary exposures from pyriproxyfen in food as follows: i. Acute exposure. Acute dietary risk assessments are performed for a fooduse 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. An aRfD for females 13   50 years old and the general population, including infants and children, was not selected because an acute oral endpoint attributed to a single dose exposure could not be identified in any of the toxicology data base, including maternal toxicity in the developmental toxicity studies. Thus, the risk from acute exposure is considered negligible. ii. Chronic exposure. In conducting this chronic dietary risk assessment the Dietary Exposure Evaluation Model software with the Food Commodity Intake Database ( DEEM FCIDTM), version 1.3 analysis evaluated the individual food consumption as reported by respondents in the United States Department of Agricluture ( USDA) 1994   1996 and 1998 Nationwide Continuing Surveys of Food Intake by Individuals ( CSFII) and accumulated exposure to the chemical for each commodity. The following assumptions were made for the chronic exposure assessments: a. A tier 1 ( assumptions: Tolerance level residues and 100 percent crop treated ( PCT) was conducted. b. The established tolerances of 40 CFR 180.510 and the new tolerances established in this document were included in the analysis. c. Anticipated residues and PCT were not used in this analysis. d. The processing factors applied were the DEEM default values. For chronic dietary risk, EPA's level of concern is > 100% cPAD. Dietary exposure estimates for representative population subgroups are presented in Table 3 of this unit. The results of the chronic analysis indicate that the estimated chronic dietary risk associated with the existing and EPArecommended uses of pyriproxyfen is below EPA's level of concern.

Cancer. In accordance with the Agency's 1986 Guidelines for Carcinogenic Risk Assessment, the RfD/ Peer Review Committee classified pyriproxyfen as a `` Group E'' chemicalnegative for carcinogenicity to humans. This classification is based on the lack of evidence of carcinogenicity in mice and rats. iv. Anticipated residue and PCT information. Anticipated residues and PCT information was not used in the Agency's assessment. 2. Dietary exposure from drinking water. The Agency lacks sufficient monitoring exposure data to complete a comprehensive dietary exposure analysis and risk assessment for pyriproxyfen in drinking water. Because the Agency does not have comprehensive monitoring data, drinking water concentration estimates are made by reliance on simulation or modeling taking into account data on the physical characteristics of pyriproxyfen. The Agency uses the Generic Estimated Environmental Concentration ( GENEEC) or the Pesticide Root Zone/ Exposure Analysis Modeling System ( PRZM/ EXAMS) to estimate pesticide concentrations in surface water and SCIGROW which predicts pesticide concentrations in groundwater. In general, EPA will use GENEEC ( a tier 1 model) before using PRZM/ EXAMS ( a tier 2 model) for a screening level assessment for surface water. The GENEEC model is a subset of the PRZM/ EXAMS model that uses a specific highend runoff scenario for pesticides. GENEEC incorporates a farm pond scenario, while PRZM/ EXAMS incorporate an index reservoir environment in place of the previous pond scenario. The PRZM/ EXAMS model includes a percent crop area factor as an adjustment to account for the maximum percent crop coverage within a watershed or drainage basin. None of these models include consideration of the impact processing ( mixing, dilution, or treatment) of raw water for distribution as drinking water would likely have on the removal of pesticides from the source water. The primary use of these models by the Agency at this stage is to provide a coarse screen for sorting out pesticides for which it is highly unlikely that drinking water concentrations would ever exceed human health levels of concern. Since the models used are considered to be screening tools in the risk assessment process, the Agency does not use estimated environmental concentrations ( EECs) from these models to quantify drinking water exposure and risk as a % RfD or % PAD.

SGM 07MRR1 10978 Federal Register / Vol. 68, No. 45 / Friday, March 7, 2003 / Rules and Regulations Instead drinking water levels of comparison ( DWLOCs) are calculated and used as a point of comparison against the model estimates of a pesticide's concentration in water. DWLOCs are theoretical upper limits on a pesticide's concentration in drinking water in light of total aggregate exposure to a pesticide in food, and from residential uses. Since DWLOCs address total aggregate exposure to pyriproxyfen they are further discussed in the aggregate risk in Unit III. E. Pyriproxyfen is relatively long lived in soil and water, with variable halflives of approximately 2 weeks to 2 months. Pyriproxyfen is immobile, as indicated by the relative mobility scheme in Dragun ( 1998) for five soils and one sediment. The registrant determined the half lives, 6.8 and 9 days, respectively, for the phenyl label and pyridyl label portions of pyriproxyfen. Since there is only one value, the longest half life ( 9 days) was multiplied by 3 using EFED input guidance. Thus, the aerobic soil half life in the modeling assessment was 27 days. EPA determined that the residue of concern in water is pyriproxyfen per se. Drinking water estimates include surface water EDWCs based on the linked PRZM/ EXAMS models and the SCI GROW groundwater regression model, which was developed from studies with different hydrology and study conditions. Both models assumed a maximum seasonal application rate of 0.11 lb active ingredient ( ai)/ acre ( A), 3 times per year ( citrus and stone fruit). Based on the PRZM/ EXAMS model the EECs of pyriproxyfen for surface water was estimated to be 2.15 parts per billion ( ppb) for the peak concentration, and 0.40 ppb for the long term average. Based on the SCI GROW model the EECs of pyriproxyfen for groundwater was estimated to be 0.006 ppb for both the acute and chronic exposure. 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 currently registered for use on the following residential nondietary sites: 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). There is a potential for short term dermal and inhalation exposures to pet owners and homeowners who apply products containing pyriproxyfen ( handlers); however, EPA did not select short term dermal or inhalation endpoints. Therefore, due to the lack of toxicity observed in animal testing, no residential pet owner/ homeowner handler risk of concern is expected. Toddlers could potentially be exposed to pyriproxyfen residues on treated carpets, floors, furniture, and pets. There is potential for exposure expected for the following scenarios: i. Hand to mouth. Short, intermediate, and long term hand tomouth exposures by toddlers from treated carpets, flooring ( note the efficacy of carpet powders is approximately 365 days). ii. Hand to mouth. Short and intermediate term hand to mouth exposures by toddlers from petting treated animals ( shampoos, sprays, spoton treatments, and collars). Long term hand to mouth exposures by toddlers from petting treated animals ( pet collars; note efficacy of pet collars up to 395 days). iii. Dermal. Long term dermal exposures from treated carpets, flooring, and pets ( note that treated furniture is included in the carpet/ flooring assessment). Due to the lack of toxicity observed in animal testing, the Agency did not select any short or intermediate term dermal endpoints and no dermal risk of concern for these durations is expected. A long term dermal assessment is included, since EPA selected a long term dermal endpoint. iv. Ingestion of granules or bait by toddlers ( acute, episodic event). For the granular ingestion scenario, it should be noted that the Agency believes that if a toddler were to be exposed to a pellet/ granular formulation ( i. e., ant bait), the event is most likely to be `` episodic,'' that is, a one time occurrence and not likely to be repeated. It is not likely that a toddler would repeatedly locate and ingest very small, sand colored granules. For pyriproxyfen, EPA did not select an acute dietary endpoint, since an appropriate endpoint could not be attributed to a single oral dose; therefore, no acute dietary risk of concern is expected. Exposure and risk estimates from post application exposure to indoor crack and crevice treatments are not presented in this assessment, as indoor broadcast treatments ( i. e., carpet powders and sprays) are anticipated to have a higher exposure potential. Additionally, the Agency acknowledges that pet owners could retreat the home environment and/ or the pet near the end of the efficacy period identified on the product labels. However, there are no chemical specific residue data for pyriproxyfen to determine the dissipation rate of residues or whether residues may be additive upon retreatment. Therefore, a tier 1 assessment was performed based on day 0 residues without accounting for daily residue dissipation. EPA anticipates that this assessment is protective as pyriproxyfen residues would be expected to dissipate from day 0 residue values. 4. Cumulative exposure to substances with a common mechanism of toxicity. Section 408( b)( 2)( D)( v) of the 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 does not have, at this time, available data to determine whether pyriproxyfen has a common mechanism of toxicity with other substances or how to include this pesticide in a cumulative risk assessment. Unlike other pesticides for which EPA has followed a cumulative risk approach based on a common mechanism of toxicity, pyriproxyfen does not appear to produce a toxic metabolite produced by other substances. For the purposes of this tolerance action, therefore, EPA has not assumed that pyriproxyfen has 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 the final rule for Bifenthrin Pesticide Tolerances ( 62 FR 62961, November 26, 1997).

D. Safety Factor for Infants and Children 1. In general. Section 408 of the FFDCA provides that EPA shall apply an additional tenfold margin of safety for infants and children in the case of threshold effects to account for prenatal and postnatal toxicity and the completeness of the data base on toxicity and exposure unless EPA determines that a different margin of safety will be safe for infants and children. Margins of safety are incorporated into EPA risk assessments either directly through use of a MOE analysis or through using uncertainty ( safety) factors in calculating a dose level that poses no appreciable risk to humans.

SGM 07MRR1 10979 Federal Register / Vol. 68, No. 45 / Friday, March 7, 2003 / Rules and Regulations 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 pre/ postnatal exposure in the 2   generation reproduction study. 3. Conclusion. There is a complete toxicity data base for pyriproxyfen and exposure data are complete or are estimated based on data that reasonably accounts for potential exposures. EPA determined that the 10X safety factor to protect infants and children should be reduced to 1X because there was no evidence of prenatal or postnatal extra sensitivity or increased susceptibility in developmental studies in rats and rabbits, and in reproduction studies in rats. Likewise, there was no quantitative or qualitative evidence of increased susceptibility to rat or rabbit fetuses identified in the guideline prenatal developmental toxicity studies for rats and rabbits. Additionally, in the two non guideline studies that evaluated perinatal and prenatal development, there was no evidence of quantitative or qualitative increased susceptibility. In one study, when pregnant rats were treated from gestation day 17 to lactation day 20, the resulting toxicity was comparable between adults ( clinical signs, decreased body weight gain and food consumption) and offspring ( decreased body weight and dilation of the renal pelvis) at the same dose. In the other study, when rats were exposed to pyriproxyfen prior to and in the early stages of pregnancy, no developmental toxicity was seen at the limit dose. Lastly, in the reproduction toxicity study, offspring toxicity ( decreased body weight on pups during lactation days 14 to 21) occurred only in the presence of decreases in body weight in parental animals at the same dose level ( i. e., comparable toxicity in adults and offspring). E. Aggregate Risks and Determination of Safety To estimate total aggregate exposure to a pesticide from food, drinking water, and residential uses, the Agency calculates DWLOCs which are used as a point of comparison against the model estimates of a pesticide's estimated environmental concentration in water ( EECs). DWLOC values are not regulatory standards for drinking water. DWLOCs are theoretical upper limits on a pesticide's concentration in drinking water in light of total aggregate exposure to a pesticide in food and residential uses. In calculating a DWLOC, the Agency determines how much of the acceptable exposure ( i. e., the PAD) is available for exposure through drinking water ( e. g., allowable chronic water exposure ( mg/ kg/ day) = cPAD  ( average food + residential exposure)). This allowable exposure through drinking water is used to calculate a DWLOC. A DWLOC will vary depending on the toxic endpoint, drinking water consumption, and body weights. Default body weights and consumption values as used by the EPA Office of Water are used to calculate DWLOCs: 2 L/ 70 kg ( adult male), 2 L/ 60 kg ( adult female), and 1 L/ 10 kg ( child). Default body weights and drinking water consumption values vary on an individual basis. This variation will be taken into account in more refined screening level and quantitative drinking water exposure assessments. Different populations will have different DWLOCs. Generally, a DWLOC is calculated for each type of risk assessment used: Acute, short term, intermediate term, chronic, and cancer. When EECs for surface water and groundwater are less than the calculated DWLOCs, OPP concludes with reasonable certainty that exposures to the pesticide in drinking water ( when considered along with other sources of exposure for which OPP has reliable data) would not result in unacceptable levels of aggregate human health risk at this time. Because OPP considers the aggregate risk resulting from multiple exposure pathways associated with a pesticide's uses, levels of comparison in drinking water may vary as those uses change. If new uses are added in the future, OPP will reassess the potential impacts of residues of the pesticide in drinking water as a part of the aggregate risk assessment process. 1. Acute risk. An acute dietary RfD for females 13   49 and the general U. S. population, including infants and children, was not selected because an acute oral endpoint attributable to a single dose exposure could not be identified in the toxicology data base, including maternal toxicity in the developmental toxicity studies. No acute dietary risk is expected. 2. Chronic risk. Using the exposure assumptions described in this unit for chronic exposure, EPA has concluded that exposure to pyriproxyfen from food will utilize 1.1% of the cPAD for the U. S. population, 2.0% of the cPAD for all infant, s and 3.9% of the cPAD for children 1   2 years old. Pyriproxyfen is the active ingredient in many registered residential products for flea and tick control on pets and in the home for ant and roach control for indoor and outdoor applications. Based on the use pattern, the residential assessment was performed for toddlers since they are anticipated to have the higher chronic residential exposure to residues of pyriproxyfen. The total chronic food and residential aggregate MOEs range from 850 to 13,000. As these MOEs are greater than 100, the chronic aggregate risk does not exceed EPA's level of concern. In addition, there is potential for chronic dietary exposure to pyriproxyfen in drinking water. After calculating DWLOCs and comparing them to the EECs for surface and ground water, EPA does not expect the aggregate exposure to exceed 100% of the cPAD, as shown in Table 4 of this unit:

SGM 07MRR1 10980 Federal Register / Vol. 68, No. 45 / Friday, March 7, 2003 / Rules and Regulations 3. Short term risk. Short term aggregate exposure takes into account residential exposure plus chronic exposure to food and water ( considered to be a background exposure level). Pyriproxyfen is currently registered for use that could result in short term residential exposure and the Agency has determined that it is appropriate to aggregate chronic food and water and short term exposures for pyriproxyfen. Using the exposure assumptions described in this unit for short term exposures, EPA has concluded that food and residential exposures aggregated result in aggregate MOEs of 26,000 for the U. S. population, 1,800 for all infants(< 1 year old), and 1,600 for children ( 1   2 years old). These aggregate MOEs do not exceed the Agency's level of concern for aggregate exposure to food and residential uses. In addition, short term DWLOCs were calculated and compared to the EECs for chronic exposure of pyriproxyfen in ground and surface water. After calculating DWLOCs and comparing them to the EECs for surface and ground water, EPA does not expect short term aggregate exposure to exceed the Agency's level of concern, as shown in Table 5 of this unit:

TABLE 5.   AGGREGATE RISK ASSESSMENT FOR SHORT TERM EXPOSURE TO PYRIPROXYFEN Population Subgroup Aggregate MOE ( Food + Residential) Target MOE Surface Water EEC ( ppb) Ground Water EEC ( ppb) Short Term DWLOC ( ppb)

U. S. population 26,000 100 0.40 0.006 35,000 All infants (< 1 year old 1,800 100 0.40 0.006 9,400 Children ( 1   2 years old) 1,600 100 0.40 0.006 9,400 Females ( 13   49 years old) 37,000 00 0.40 0.006 30,000 4. Intermediate term risk. Intermediate term aggregate exposure takes into account residential exposure plus chronic exposure to food and water ( considered to be a background exposure level). Pyriproxyfen is currently registered for use( s) that could result in intermediate term residential exposure and the Agency has determined that it is appropriate to aggregate chronic food and water and intermediate term exposures for pyriproxyfen. Using the exposure assumptions described in this unit for intermediateterm exposures, EPA has concluded that food and residential exposures aggregated result in aggregate MOEs of 9,200 for the U. S. population, 650 for all infants (< 1 year old, and 580 for children ( 1   2 years old). These aggregate MOEs do not exceed the Agency's level of concern for aggregate exposure to food and residential uses. In addition, intermediate term DWLOCs were calculated and compared to the EECs for chronic exposure of pyriproxyfen in ground and surface water. After calculating DWLOCs and comparing them to the EECs for surface and ground water, EPA does not expect intermediate term aggregate exposure to exceed the Agency's level of concern, as shown in Table 6 of this unit:

TABLE 6.   AGGREGATE RISK ASSESSMENT FOR INTERMEDIATE TERM EXPOSURE TO PYRIPROXYFEN Population Subgroup Aggregate MOE ( Food + Residential) Target MOE Surface Water EEC ( ppb) Ground Water EEC ( ppb) Intermediate Term DWLOC ( ppb)

U. S. population 9,200 100 0.40 0.006 12,000 All infants (< 1 year old) 650 100 0.40 0.006 3,000 Children ( 1   2 years old) 580 100 0.40 0.006 3,000 Females ( 13   49 years old) 13,000 100 0.40 0.006 10,000 5. Aggregate cancer risk for U. S. population. There was no evidence of carcinogenicity in a 78 week mouse feeding study and a 2   year rat feeding study. Pyriproxyfen was classified as a `` Group E'' chemical ( no evidence of carcinogenicity to humans) by the Agency based on the absence of evidence of carcinogenicity in male and female rats as well as in male and female mice. 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, and to infants and children from aggregate exposure to pyriproxyfen residues.

IV. Other Considerations A. Analytical Enforcement Methodology In conjunction with the residue studies on cabbage, cauliflower, mustard greens, cantaloupe, cucumber, summer squash, olive, okra, and sugar apple, the petitioner submitted adequate concurrent recovery data for a gas chromatography/ nitrogen phosphorous detector ( GC/ NPD) method ( RM   33P   1   3a) used to determine residues of pyriproxyfen in/ on these crops. The method has undergone an adequate radiovalidation, independent laboratory validation ( ILV) trial, petition method validation ( PMV) trial, and has been forwarded to the Food and Drug Administration ( FDA) for inclusion in Pesticide Analytical Method ( PAM) Vol. II ( DP Barcode D257337, W. Donovan, 7/ 1/ 99). HED concludes that the GC/ NPD method RM   33P   1   3a is adequate for enforcement of the recommended VerDate Jan< 31> 2003 17: 26 Mar 06, 2003 Jkt 200001 PO 00000 Frm 00028 Fmt 4700 Sfmt 4700 E:\ FR\ FM\ 07MRR1.

As tolerances for residues of pyriproxyfen in livestock commodities are not required at this time, enforcement methodology for determining residues in livestock are not required. MRM testing data have previously been provided ( PP# 6F04737, DP Barcode D228556, J. Garbus, 5/ 6/ 97) for pyriproxyfen. Pyriproxyfen was recovered from fortified apple and cotton samples through protocols A, C, D, E, and F. The results have been forwarded to FDA. Adequate enforcement methodology ( example   gas chromotography) is available to enforce the tolerance expression. The method may be requested from: Francis Griffith, Analytical Chemistry Branch, Environmental Science Center, 701 Mapes Rd., Ft. Meade, MD 20755   5350; telephone number: ( 410) 305   2905; email address: griffith. francis@ epa. gov.

B. International Residue Limits There are no Codex, Canadian, or Mexican maximum residue limits ( MRLs) for residues of pyriproxyfen in/ on any of the crops involved in the proposed new uses. Therefore, international harmonization is not an issue at this time.

V. Conclusion Therefore, the tolerances are established for residues of pyriproxyfen, [ 2[ 1 methyl 2( 4 phenoxyphenoxy) ethoxy] pyridine], in or on Brassica, head and stem, subgroup 5A; Brassica, leafy greens, subgroup 5B; vegetable, cucurbit, group 9; olive and olive, oil at 0.70, 2.0, 0.10, 1.0, and 2.0 ppm. respectively.

VI. Objections and Hearing Requests Under section 408( g) of the FFDCA, as amended by the FQPA, any person may file an objection to any aspect of this regulation and may also request a hearing on those objections. The EPA procedural regulations which govern the submission of objections and requests for hearings appear in 40 CFR part 178. Although the procedures in those regulations require some modification to reflect the amendments made to the FFDCA by the FQPA, EPA will continue to use those procedures, with appropriate adjustments, until the necessary modifications can be made. The new section 408( g) of the FFDCA provides essentially the same process for persons to `` object'' to a regulation for an exemption from the requirement of a tolerance issued by EPA under new section 408( d) of FFDCA, as was provided in the old sections 408 and 409 of the FFDCA. However, the period for filing objections is now 60 days, rather than 30 days.

B. When Will the Agency Grant a Request for a Hearing? A request for a hearing will be granted if the Administrator determines that the material submitted shows the following: There is a genuine and substantial issue of fact; there is a reasonable possibility that available evidence identified by the requestor would, if established resolve one or more of such issues in favor of the requestor, taking into account VerDate Jan< 31> 2003 17: 26 Mar 06, 2003 Jkt 200001 PO 00000 Frm 00029 Fmt 4700 Sfmt 4700 E:\ FR\ FM\ 07MRR1. SGM 07MRR1 10982 Federal Register / Vol. 68, No. 45 / Friday, March 7, 2003 / Rules and Regulations uncontested claims or facts to the contrary; and resolution of the factual issues( s) in the manner sought by the requestor would be adequate to justify the action requested ( 40 CFR 178.32).

VII. Statutory and Executive Order Reviews This final rule establishes a tolerance under section 408( d) of the 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 rule has been exempted from review under Executive Order 12866 due to its lack of significance, this rule is not subject to Executive Order 13211, Actions Concerning Regulations That Significantly Affect Energy Supply, Distribution, or Use ( 66 FR 28355, May 22, 2001). 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., or 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). 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); or OMB review or any Agency action under Executive Order 13045, entitled Protection of Children from Environmental Health Risks and Safety Risks ( 62 FR 19885, April 23, 1997). 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). Since tolerances and exemptions that are established on the basis of a petition under section 408( d) of the 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. In addition, the Agency has determined that this action will not have a substantial direct effect on States, on the relationship between the national government and the States, or on the distribution of power and responsibilities among the various levels of government, as specified in Executive Order 13132, entitled Federalism( 64 FR 43255, August 10, 1999). Executive Order 13132 requires EPA to develop an accountable process to ensure `` meaningful and timely input by State and local officials in the development of regulatory policies that have federalism implications.'' `` Policies that have federalism implications'' is defined in the Executive order to include regulations that have `` substantial direct effects on the States, on the relationship between the national government and the States, or on the distribution of power and responsibilities among the various levels of government.'' This final rule directly regulates growers, food processors, food handlers, and food retailers, not States. This action does not alter the relationships or distribution of power and responsibilities established by Congress in the preemption provisions of section 408( n)( 4) of the FFDCA. For these same reasons, the Agency has determined that this rule does not have any `` tribal implications'' as described in Executive Order 13175, entitled Consultation and Coordination with Indian Tribal Governments ( 65 FR 67249, November 6, 2000). Executive Order 13175, requires EPA to develop an accountable process to ensure `` meaningful and timely input by tribal officials in the development of regulatory policies that have tribal implications.'' `` Policies that have tribal implications'' is defined in the Executive order to include regulations that have `` substantial direct effects on one or more Indian tribes, on the relationship between the Federal Government and the Indian tribes, or on the distribution of power and responsibilities between the Federal Government and Indian tribes.'' This rule will not have substantial direct effects on Tribal governments, on the relationship between the Federal Government and Indian tribes, or on the distribution of power and responsibilities between the Federal Government and Indian Tribes, as specified in Executive Order 13175. Thus, Executive Order 13175 does not apply to this rule.

VIII. Congressional Review Act The Congressional Review Act, 5 U. S. C. 801 et seq., as added by the Small Business Regulatory Enforcement Fairness Act of 1996, generally provides that before a rule may take effect, the agency promulgating the rule must submit a rule report, which includes a copy of the rule, 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).
