BILLING CODE 4910-13-P


Within each agronomic group, a variety of cultural practices are required to maintain the included crops. These practices are varied and typically involve light to heavy contact with immature plants as well as with more mature plants. HED selected transfer coefficient values in its revision of Policy 003 to represent this range of exposures within each agronomic group. In the policy, transfer coefficients were placed in 1 of 5 generic categories based on the exposures relative to that group. These 5 categories include: very low exposure, low exposure, medium exposure, high exposure, and very high exposure. Numerical values were not necessarily assigned to each category for each crop group. Selections depended upon the actual agronomic practices that were identified for each group ( i. e., some groups had 2 assigned transfer coefficients while others had 5). The transfer coefficient values which have been used are excerpted directly from Agency policy 003. [ The nursery crop group data have not yet been formally included in EPA Policy 3. However, the studies in this area submitted by ARTF have been reviewed and used Page 67 of 91 since they will be integrated into Policy 3.]

2.2.2 Data/ Assumptions for Postapplication Exposure Scenarios A series of assumptions and exposure factors served as the basis for completing the occupational postapplication worker risk assessments. Each assumption and factor is detailed below on an individual basis. In addition to these values, transfer coefficient values were used to calculate risk estimates. The transfer coefficients were taken from HED's revised policy entitled Policy 003.1 Science Advisory Council for Exposure Policy Regarding Agricultural Transfer Coefficients ( August 7, 2000). The assumptions and factors used in the risk calculations are presented below:

° There are many factors that are common to handler and postapplication risk assessments such as body weights, duration, and application rates. See Section <IP_ADDRESS> for these values. In the postapplication risk assessment, maximum application rates were considered.

° Levels of Concern: HED has established levels of concern ( LOC) for occupational postapplication risks   margins of exposure of less than 1000 for occupational noncancer dermal and inhalation risks are a concern.

° Turf Transferrable Residues: No triadimefon specific turf transferrable residue ( TTR) data were available. Therefore, this assessment uses HED's default assumption that 5 percent of the application rate is available on day 0 ( i. e., 12 hours after application) and the residue dissipates at a rate of 10 percent per day.

° Dislodgeable Foliar Residues: No triadimefon specific dislodgeable foliar residue ( DFR) data were available. Therefore, this assessment uses HED's default assumption that 20 percent of the application rate is available on day 0 ( i. e., 12 hours after application) and the residue dissipates at a rate of 10 percent per day.

° Exposures were calculated to reflect default TTR and DFR values over time coupled with surrogate transfer coefficients as outlined in HED's revised policy.

2.2.3 Occupational Postapplication Exposure and Noncancer Risk Estimates Occupational noncancer risks were calculated using a Margin of Exposure ( MOE), which is a ratio of the daily dose to the toxicological endpoint of concern. Postapplication risks diminish over time because triadimefon residues eventually dissipate in the environment. As a result, risks were calculated over time based on changing residue levels.

Daily Exposure: Daily dermal exposures were calculated on each postapplication day Page 68 of 91 after application using the following equation ( see equation D2 20 from Series 875 Occupational and Residential Test Guidelines: Group B Postapplication Exposure Monitoring Test Guidelines and Residential SOP 3.2: Postapplication Dermal Potential Doses from Pesticide Residues on Gardens):

DE( t) ( mg/ day) = ( TR( t) ( ìg/ cm2) x TC ( cm2/ hr) x Hr/ Day)/ 1000 ( ìg/ mg)

Where:

DE( t) = Daily exposure or amount deposited on the surface of the skin at time ( t) attributable for activity in a previously treated area, also referred to as potential dose ( mg ai/ day); TR( t) = Transferable residues that can either be dislodgeable foliar or turf transferable residue at time " t" ( ìg/ cm2); TC = Transfer Coefficient ( cm2/ hour); and Hr/ day = Exposure duration meant to represent a typical workday ( hours).

Note that the TR( t) input may represent levels on the day of application in the case of short term risk calculations.

Daily Dose and Margins of Exposure: The use of dissipation data and the manner in which daily postapplication dermal exposures were calculated are inherently different than with handler exposures. However, once daily exposures are calculated, the calculation of daily absorbed dose and the resulting Margin of Exposures use the same algorithms that are described above for the handler exposures ( See Section 2.1.3). These calculations are completed for each day or appropriate block of time after application.

2.2.3 Noncancer Risk Summary A summary of the noncancer postapplication risks are provided in Table 13. The occupational postapplication exposure and risk assessment for agricultural crop uses of triadimefon indicates that risks are not a concern at day 0 ( i. e., 12 hours after application) for all crops and all postapplication activities.

It should be noted that there were a few scenarios for which no appropriate exposure data are known to exist or ongoing transfer coefficient studies have not yet been submitted ( e. g., ARTF nursery and ornamental data). The scope of HED's revised policy 003 for transfer coefficients should also be considered, as it only quantitatively addresses risks where the transfer coefficient model is appropriate ( i. e., where foliar contact is known to exist).

2.2.4 Occupational Postapplication Exposure and Risk Estimates for Cancer Since no toxicological endpoint of concern was identified for cancer, cancer risks from occupational postapplication exposures were not assessed.

2.2.5 Summary of Occupational Postapplication Risk Concerns and Data Gaps HED has used the most up to date information available to complete this postapplication risk assessment for triadimefon. Several data gaps exist, such as a lack of triadimefon specific Page 71 of 91 postapplication studies and lack of transfer coefficients for certain crop activities.

2.2.6 Recommendations for Refining Occupational Postapplication Risk Assessment To refine this occupational risk assessment, data on actual use patterns including rates, timing, and the kinds of tasks that are required to produce agricultural commodities and other products would better characterize triadimefon risks. In addition, triadimefon specific TTR or DFR data could refine exposure and risk estimates. Exposure studies for many cultural practices that lack data or that are not well represented in the revised transfer coefficient policy should also be considered based on the data gaps identified above.

3.0 Residential and Other Non Occupational Exposures and Risks It has been determined there is a potential for exposure in residential settings during the application process for homeowners who use products containing triadimefon. There is also a potential for exposure from entering triadimefon treated areas, such as lawns, golf courses, and home gardens that could lead to exposures to adults and children. Risk assessments have been completed for both residential handler and postapplication scenarios. ~~

3.1 Residential Handler Exposures and Risks HED uses the term " handlers" to describe those individuals who are involved in the pesticide application process. HED believes that there are distinct tasks related to applications and that exposures can vary depending on the specifics of each task as was described above for occupational handlers 3.1.1 Handler Exposure Scenarios Scenarios are used to define risks based on the U. S. EPA Guidelines for Exposure Assessment ( U. S. EPA; Federal Register Volume 57, Number 104; May 29, 1992). Assessing exposures and risks resulting from residential uses is very similar to assessing occupational exposures and risks, with the following exceptions:

° Residential handler exposure scenarios are considered to be short term only, due to the infrequent use patterns associated with homeowner products.

° A tiered approach for personal protection using increasing levels of PPE is not used in residential handler risk assessments. Homeowner handler assessments are based on the assumption that individuals are wearing shorts, short sleeved shirts, socks, and shoes.

° Homeowner handlers are expected to complete all tasks associated with the use of a pesticide product including mixing/ loading if needed as well as the application. Page 72 of 91 ° Label use rates and use information specific to residential products serve as the basis for the risk calculations.

° Area/ volumes of spray or chemical used in the risk assessment are based on HED's guidance specific to residential use patterns.

It has been determined that exposure to pesticide handlers is likely during the residential use of triadimefon in a variety of outdoor environments, including on lawns, gardens, and ornamentals. The anticipated use patterns and current labeling indicate several residential handler exposure scenarios based on the types of equipment and techniques that can potentially be used to make triadimefon applications. The quantitative exposure/ risk assessment developed for residential handlers is based on these scenarios. [ Note: The scenario numbers correspond to the tables of risk calculations included in the residential risk calculations in the appendices.]

3.1.2 Data and Assumptions For Handler Exposure Scenarios A series of assumptions and exposure factors served as the basis for completing the residential handler risk assessments. Each assumption and factor is detailed below. In addition to these factors, unit exposure values were used to calculate risk estimates. Mostly, these unit exposure values were taken from the Pesticide Handlers Exposure Database ( PHED) and the Outdoor Residential Exposure Task Force ( ORETF) studies. In other cases, chemical specific exposure data were submitted to support the reregistration of triadimefon. Both PHED and the individual studies are presented below. [ Note: Several of the assumptions and factors used for the assessment are similar to those used in the occupational assessment presented above. As such, only factors that are unique to the residential scenarios are presented below.] Page 73 of 91 Assumptions and Factors: The assumptions and factors used in the risk calculations include:

° Exposure factors used to calculate daily exposures to handlers were based on applicable data if available. When appropriate data is unavailable, values from a scenario deemed similar might be used.

° HED always considers the maximum application rates allowed by labels in its risk assessments. If additional information such as average or typical rates are available, these values also may be used to allow risk managers to make a more informed risk management decision. Average/ typical application rates were not available for residential scenarios.

° Residential risk assessments are based on estimates of what homeowners would typically treat, such as the size of a lawn or the size of a garden. The factors used for the triadimefon assessment were from the Health Effects Division Science Advisory Committee Policy 12: Recommended Revisions to the Standard Operating Procedures for Residential Exposure Assessment which was completed on February 22, 2001, and on professional judgement. The daily volumes handled and area treated used in each residential scenario are provided in Table 4.

Residential Handler Exposure Studies: The unit exposure values that were used in this assessment were based on the Outdoor Residential Exposure Task Force studies and the Pesticide Handler Exposure Database ( PHED, Version 1.1 August 1998) [ Note: PHED and some ORETF studies are described above in Section 2.1.1.]

ORETF Handler Studies  OMA001 OMA004 ( MRID 449722 01) A report was submitted by the ORETF ( Outdoor Residential Exposure Task Force) that presented data in which the application of various products used on turf by homeowners and lawncare operators ( LCOs) was monitored. All of the data submitted in this report were completed in a series of studies.

Homeowner Liquid Applications with a Ready to use Hose end Sprayer and a Dial Type Hoseend Sprayer ( MRID 449722 01): A mixer/ loader/ applicator study was performed by the Outdoor Residential Exposure Task Force ( ORETF) using diazinon ( 25% EC) as a surrogate compound to determine " generic" exposures to individuals applying a pesticide to turf with a garden hose end sprayer. Surrogate chemicals were chosen by the Task Force for their representativeness based on physical chemical properties and other factors. The study was designed to simulate a typical application event for a homeowner applying pesticides to home lawns via a hose end sprayer. Each replicate monitored the test subject treating 5,000 square feet of turf at a nominal application rate of 4 pounds active ingredient per acre and handling a total of 0.5 pounds active ingredient per replicate. The average time per replicate was 75 minutes. A total of 60 replicates were monitored using 30 test subjects ( two replicates each). Thirty applicator replicates were monitored using a ready to use ( RTU) product ( Bug B Gon) packaged in a 32 fl. oz. screw on container. These containers were attached to garden hose ends. An additional 30 Page 74 of 91 mixer/ loader/ applicator replicates were monitored using Diazinon Plus also packaged in 32 fl. oz. plastic bottles. This product required the test subjects to pour the product into dial type sprayers ( DTS) that were attached to garden hose ends.

Dermal and inhalation exposures were monitored using passive dosimetry ( inner and outer whole body dosimeters, hand washes, face/ neck wipes, and personal inhalation monitors with OVS tubes). The inner samples represent a single layer of clothing. Inhalation exposure was calculated using an assumed respiratory rate of 17 liters per minute for light work ( NAFTA, 1999), the actual sampling time for each individual, and the pump flow rate. No gloves were worn in any replicate. All results were normalized for the amount of active ingredient handled. The QA/ QC data are within an acceptable range and the study results are corrected for field recoveries. The unit exposure values are presented below. [ Note: All values are geometric means as the data were lognormally distributed.]

ORETF Handler Studies  OMA005 ( MRID 445185 01) A report was submitted by the ORETF ( Outdoor Residential Exposure Task Force) that presented data in which the application of various products used on fruit trees and ornamentals by homeowners was monitored. All of the data submitted in this report were completed in a series of studies.

Homeowner Liquid Applications to Fruit Trees and Ornamental Plants with a Hose end Sprayer and a Low Pressure Handwand ( MRID 445185 01): Applications of Sevin Liquid ® Carbaryl insecticide [ RP 2 liquid ( 21%)] were made by volunteers to two young citrus trees and two shrubs in each replicate that was monitored in the study. The test field was located only in Florida. Twenty ( 20) replicates were monitored using hose end sprayer ( Ortho ® DIAL or Spray ® hose end sprayer), and 20 replicates were monitored using hand held pump sprayers ( low pressure handwands).

Each replicate opened the end use product, added it to the hose end sprayer or hand held pump and then applied it to the trees and shrubs. After application to two trees and two shrubs dosimeters were collected. Inhalation exposure was monitored with personal air sampling pumps Page 75 of 91 with OVS tubes attached to the shirt collar in the breathing zone. Dermal exposure was assessed by extraction of carbaryl from inner and outer 100 percent cotton dosimeters. The inner and outer dosimeters were segmented into: lower and upper arms, lower and upper legs, front and back torso. No gloves were worn therefore hand exposure was assessed with 400 ml handwash with 0.01 percent Aerosol OT 75 sodium dioctyl sulfosuccinate ( OTS). One hundred percent cotton handkerchiefs wetted with 25 ml OTS were used to wipe face and neck to determine exposure.

Field fortification recoveries for passive dosimeters averaged 88.3 percent for inner and 76.2 percent for outer dosimeters. Face and neck wipe fortifications average 82.5 percent. Handwash and inhalation OVS tube field fortification averaged > 90 percent. Inner and outer dosimeter and face and neck wipe residues were adjusted for field fortification results. Handwash and inhalation residues were not adjusted.

Laboratory method validation for each matrix fell within the acceptable range of 70 to 120 percent. The limit of quantitation ( LOQ) was 1.0 µ g/ sample for all media except the inhalation monitors where the LOQ was 0.01 µ g/ sample. The limit of detection ( LOD) was 0.5 µ g/ sample for all media except the inhalation monitors where the LOQ was 0.005 µ g/ sample.

For use in reregistration documents, the dermal exposure was calculated by adding the values from the hand rinses, face/ neck wipes to the outer dosimeter lower legs and lower arms plus the inner dosimeter front and rear torso, upper legs and upper arms. This accounts for the residential handler wearing short sleeved shirt and short pants. The results for the low pressure handwand are summarized in Table 15 below.

The distribution of the unit exposure values is categorized as normal, lognormal, or " other" ( i. e., neither normal nor lognormal). A central tendency value is selected from the distribution of the exposure values. These values are the arithmetic mean for normal distributions, the geometric mean for lognormal distributions, and the median for all " other" distributions. The dermal exposure had a lognormal distribution so the geometric mean value was used to determine dermal exposure. The inhalation exposure had neither a normal or lognormal distribution so the median was used to determine inhalation exposure.

3.1.3 Residential Handler Exposure and Noncancer Risk Estimates Noncancer risks were calculated using the Margin of Exposure ( MOE) as described in Section 2.1.3. Assessing exposures and risks resulting from residential uses is very similar to assessing occupational exposures and risks, except as described in Section 3.1.1.

Noncancer Risk Summary: All of the noncancer risk calculations for residential triadimefon handlers completed in this assessment are included in the appendices.

The data used by HED have provided a basic broad overview of the uses of triadimefon around a residential environment ( i. e., the database is fairly complete). As indicated above, however, it is likely that triadimefon can be used in a myriad of ways that have not specifically been identified in this assessment. HED believes that the scenarios assessed in this document represent worse case exposures and risks resulting from use of triadimefon in residential environments. It should also be noted that there were many other scenarios where medium to low PHED quality data were used to complete the assessment. Data quality should be considered in the interpretation of the uncertainties associated with each risk value presented.

Short term risks for residential handlers ( intermediate term exposures are not likely because of the intermittent nature of applications by homeowners) are presented in Table 16. The dermal risks for residential handlers are not a concern for all, except one, triadimefon residential handler scenarios. Risks remain a concern ( MOEs < 1000) for mixing/ loading/ applying liquid concentrates with a hose end sprayer ( using ORETF data) to turf ( home lawns) ( MOE = 500). The inhalation risks for residential handlers are not a concern for all residential uses of triadimefon. Page 77 of 91 Table 16.

3.1.4 Residential Handler Exposure and Risk Estimates for Cancer Residential handler cancer risks are not assessed, since no toxicological endpoint of concern for cancer was selected.

3.1.5 Summary of Risk Concerns and Data Gaps for Handlers Page 81 of 91 Generally, noncancer risks ( i. e., MOEs) associated with most scenarios are not of concern, because they exceed HED's uncertainty factor of 1000. All inhalation scenarios were not found to pose a risk with baseline attire, and only one scenario   mixing/ loading/ applying liquid concentrates with a hose end sprayer ( using ORETF data) to home lawns with an ( MOE of 500   was found to pose a risk due to dermal exposure with baseline attire.

The key data gap identified by HED for residential handlers is mixing/ loading/ applying liquids with an injector. HED has no data for this scenario and is not aware of any surrogate data that could be applied to this scenario.

3.1.6 Recommendations for Refining Residential Handler Risk Assessment In order to refine this residential risk assessment, more data on actual use patterns including rates, timing, and areas treated would better characterize triadimefon risks. Exposure studies for many equipment types that lack data or that are not well represented in PHED ( e. g., because of low replicate numbers or data quality) should also be considered based on the data gaps identified above and based on a review of the quality of the data used in this assessment.

3.2 Residential Postapplication Exposures and Risks HED uses the term " postapplication" to describe exposures to individuals that occur as a result of being in an environment that has been previously treated with a pesticide. Triadimefon can be used in many areas that can be frequented by the general population including residential areas ( e. g., home lawns and gardens). As a result, individuals can be exposed by entering these areas if they have been previously treated.

3.2.1 Residential Postapplication Exposure Scenarios A wide array of individuals of varying ages can potentially be exposed to triadimefon when they are in areas that have been previously treated. Postapplication exposure scenarios were developed for each residential setting where triadimefon can be used. Assessing postapplication exposures and risks resulting from residential uses is very similar to assessing occupational postapplication exposures and risks ( Section 2.2), except in residential assessments:

° exposures were calculated for children of differing ages as well as adults and ° non dietary ingestion exposures to toddlers were calculated ( i. e., soil ingestion, hand / object to mouth).

HED relies on a standardized approach for completing residential risk assessments that is based on current triadimefon labels and guidance contained in the following five documents:

° Series 875, Residential and Residential Exposure Test Guidelines: Group B  Postapplication Exposure Monitoring Test Guidelines ( V 5.4, Feb. 1998): This document Page 82 of 91 provides general risk assessment guidance and criteria for analysis of residue dissipation data.

° Standard Operating Procedures For Residential Exposure Assessment ( Dec. 1997): This document provides the overarching guidance for developing residential risk assessments including scenario development, algorithms, and values for inputs.

° Science Advisory Council For Exposure Policy 003.1 ( Aug. 2000): Agricultural Transfer Coefficients: This document provides transfer coefficients which have been used to assess exposures in home gardens.

° Science Advisory Council For Exposure Policy 12 ( Feb. 2001): Recommended Revisions To The Standard Operating Procedures ( SOPs) For Residential Exposure Assessment: This document provides additional, revised guidance for completing residential exposure assessments.

° Overview of Issues Related to the Standard Operating Procedures for Residential Exposure Assessment ( August 1999 Presentation To The FIFRA SAP): This document provides rationale for Agency changes in SOPs. Companion animal approach included in document used for risk assessment.

When the guidance in current labels and these documents is considered, it is clear that HED should consider children of differing ages as well as adults in its assessments. It is also clear that different age groups should be considered in different situations. The populations that were considered in the assessment include:

° Residential Adults: these individuals are members of the general population that are exposed to chemicals by engaging in activities at their residences ( e. g., in their lawns or gardens) and also in areas not limited to their residence ( e. g., golf courses or parks) previously treated with a pesticide. These kinds of exposures are attributable to a variety of activities and are usually addressed by HED in risk assessments by considering a representative activity as the basis for the exposure calculation.

° Residential Children: children are members of the general population that can also be exposed in their residences ( e. g., on lawns and other residential turfgrass areas, in gardens, on carpets and hard flooring, or from contact with treated pets). These kinds of exposures are attributable to a variety of activities such as playing outside, home gardening, playing on carpeting or hard flooring, and playing with a companion animal. Toddlers have been selected as the sentinel ( representative) population for turf, indoor flooring, and companion animal assessments. Youth aged children ( ages 10 to 12) are considered the sentinel population for a gardening assessment, because it is likely that children of this age would help with garden maintenance. Children are addressed by HED in risk assessments by considering representative activities for each age group in an exposure calculation. Page 83 of 91 The SOPs for Residential Exposure Assessment define several scenarios that apply to uses specified in current labels. These scenarios served as the basis for the residential postapplication assessment along with the modifications to them and the additional data and approaches described above. HED used this guidance to define the exposure scenarios that essentially include dermal and nondietary ingestion exposure to toddlers on treated lawns, dermal and nondietary ingestion exposure to toddlers on treated flooring, dermal exposure to youths in treated gardens, dermal and nondietary ingestion exposure to children from treated companion animals, and dermal exposure to adults in treated gardens and on treated lawns. The SOPs and the associated scenarios are presented below:

° Dose from dermal exposure on treated lawns: Postapplication dermal dose calculations for toddlers from playing on treated turf and for adults mowing and exercising on treated turf;

° Dose from hand to mouth activity from treated turf: Postapplication dose calculations for toddlers from incidental nondietary ingestion of pesticide residues on treated turf from hand to mouth transfer ( i. e., those residues that are swallowed when toddlers get pesticide residues on their hands from touching treated turf and then put their hands in their mouth);

° Dose from object to mouth activity from treated turf: Postapplication dose calculations for toddlers from incidental nondietary ingestion of pesticide residues on treated turf from object to mouth transfer ( i. e., those residues that are swallowed when toddlers put treated turf in their mouths);

° Dose from soil ingestion activity from treated turf: Postapplication dose calculations for toddlers from incidental nondietary ingestion of pesticide residues from ingesting soil in a treated turf area ( i. e., those soil residues that are swallowed when toddlers get pesticide residues on their hands from touching treated soil and then put their hands in their mouth);

° Dose from ingestion of triadimefon granules from treated turf: Postapplication dose calculations for toddlers from episodic nondietary ingestion of pesticide granules picked up from treated turf ( i. e., those residues that are swallowed when toddlers pick up granules from treated turf and put the granules in their mouth);

° Dose from dermal exposure while golfing: Postapplication dermal dose calculations for adults and youth aged children ( ages 10 to 12) while golfing.

The detailed residential postapplication calculations are presented in the appendices of this document.

3.2.2 Data and Assumptions for Residential Postapplication Exposure Scenarios Assumptions and Exposure Factors Page 84 of 91 A series of assumptions and exposure factors served as the basis for completing the residential postapplication risk assessments. The assumptions and factors used in the risk calculations are consistent with current Agency policy for completing residential exposure assessments ( i. e., SOPs for Residential Exposure Assessment). The values used in this assessment include:

° There are many factors that are common to the occupational and residential postapplication risk assessments, such as body weights for adults, analysis of residue dissipation data, and transfer coefficients used for the garden exposure scenarios. Please refer to the assumptions and factors in Section 2.1.2 for further information concerning these common values.

° HED combines risks resulting from exposures to individual applications when it is likely they can occur simultaneously based on the use pattern and the behavior associated with the exposed population. For triadimefon, HED has combined risks ( i. e., MOEs) for different kinds of exposures for one scenario:

< for turf scenarios   dermal plus hand to mouth plus object to mouth plus soil ingestion < Exposures to adults and children on treated turf have been addressed using the latest HED standard operating procedures for this scenario including:

< 5 percent of the application rate has been used to calculate the day zero TTR residue levels used for assessing risks from dermal and hand to mouth exposures, since triadimefon specific turf transferable residue study data are not available;

< 20 percent of the application rate has been used to calculate the day zero residue levels used for assessing risks from object to mouth behaviors ( a higher percent transfer has been used for object to mouth behaviors, because it involves a teething action believed to be more analogous to DFR/ leaf wash sample collection where 20 percent is also used);

< the transfer coefficients used are those presented during the 1999 Agency presentation before the FIFRA Science Advisory Panel that have been adopted in routine practice by HED;

< 3 year old toddlers are expected to weigh 15 kilograms ( representing an average weight from years one to six);

< hand to mouth exposures are based on a frequency of 20 events/ hour and a surface area per event of 20 cm2, representing the palmar surfaces of three fingers;

< saliva extraction efficiency is 50 percent meaning that every time the hand goes in the mouth approximately ½ of the residues on the hand are removed;

< object to mouth exposures are based on a 25 cm2 surface area;

< exposure durations for turfgrass scenarios are estimated to be 2 hours based on information in HED's Exposure Factors Handbook;

< soil residues are contained in the top centimeter and soil density is 0.67 mL/ gram; and Page 85 of 91 < dermal, hand and object to mouth, and soil ingestion are combined to represent an overall risk from exposure to turf, while granular ingestion is considered to be a much more episodic behavior and is considered separately by HED.

° Exposures to children and adults working in home gardens have been addressed using the latest HED approaches for this scenario including:

< youth aged children are considered along with adults;

< 12 year old youth are expected to weigh 39.1 kilograms;

< exposure durations are expected to be 40 minutes for adults and 20 minutes for youths;

< transfer coefficients for youths were calculated by adjusting the appropriate adult transfer coefficients by a 50% factor as has been done by HED since the inception of the SOPs For Residential Exposure Assessment;

< transfer coefficients for adults and youths are from the R SOPs;

< the combination of adjusting transfer coefficients for youth aged children and using appropriate body weights for the age group results in dose levels that are slightly lower than that of adults in the same activity ( the transfer coefficient reduction and body weight reduction is essentially a 1: 1 ratio); and < the DFR data used for the assessments are the default assumption that 20 percent of the application rate is available for transfer, since no triadimefon specific DFR data are available.

° Postapplication residential risks are based on maximum application rates or values specified in the SOPs For Residential Exposure Assessment.

° The Jazzercize approach is the basis for the dermal transfer coefficients as described in HED's Series 875 guidelines, SOPs For Residential Exposure Assessment, and the 1999 FIFRA SAP Overview document.

3.2.3 Residential Postapplication Exposure and Noncancer Risk Estimates Noncancer risks were calculated using the Margin of Exposure ( MOE) approach, which is a ratio of the body burden to the toxicological endpoint of concern. Exposures were calculated by considering the potential sources of exposure ( i. e., DFRs on ornamental plants and TTRs on lawns), then calculating dermal and nondietary ingestion exposures.

Dermal exposures and risks from lawn, garden, and golf course turfgrass uses were calculated in the same manner as described above in Section 2.2.3. Along with calculating these dermal exposures, other aspects of the turf exposure scenario involved calculating dose from nondietary ingestion. The algorithms used for each type of calculation are presented below which have not been previously addressed in Section 2.2.3.

Dermal Exposure from Treated Lawns ( adult and toddler) Page 86 of 91 The approach used to calculate the dermal exposures that are attributable to exposure from contacting treated lawns is:

ADD = ( TTR0 * ET * TC * DA * CF1) / BW Where:

ADD = average daily dose ( mg/ kg/ day); TTRt = turf transferable residue on day " 0" ( µ g/ cm2); ET = exposure time ( 2 hr/ day); TC = transfer coefficient ( 14,500 cm2/ hr for adults and 5,200 cm2/ hr for toddlers); DA = dermal absorption factor ( 100%); CF1 = weight unit conversion factor to convert ìg units to mg for the daily exposure ( 0.001 mg/ ìg); and BW = body weight ( 70 kg for adults and 15 kg for toddlers).

Hand to mouth Transfer of Pesticide Residues on Lawns ( toddler)

The approach used to calculate the nondietary ingestion exposures that are attributable to hand tomouth behavior on treated turf is:

ADD = ( TTR0 * SA * FQ * ET * SE * CF1) / BW Where:

ADD = average daily dose ( mg/ kg/ day); TTRt = turf transferable residue on day " 0" ( µ g/ cm2 ); SA = surface area of the hands ( 20 cm2/ event); FQ = frequency of hand to mouth activity ( 20 events/ hr); ET = exposure time ( 2 hr/ day); SE = extraction by saliva ( 50%); CF1 = weight unit conversion factor to convert ìg units in the DFR value to mg for the daily exposure ( 0.001 mg/ µ g); and BW = body weight ( 15 kg).

Object to mouth Transfer of Pesticide Residues on Lawns ( toddler)

The approach used to calculate exposures that are attributable to object to mouth behavior on treated turf that is represented by a child mouthing on a handful of turf is:

ADD = ( TTR0 * IgR* CF1) / BW Where:

ADD = average daily dose ( mg/ kg/ day); TTRt = turf transferable residue on day " 0" ( µ g/ cm2); IgR = ingestion rate of grass ( 25 cm2/ day); CF1 = weight unit conversion factor to convert the ug of residues on the grass to mg to provide units of mg/ day ( 1E 3 mg/ ug); and Page 87 of 91 BW = body weight ( 15 kg).

Incidental Ingestion of Soil from Pesticide Treated Residential Areas ( toddler)

The approach used to calculate exposures that are attributable to soil ingestion is:

ADD = ( SR0 * IgR * CF1) / BW Where:

ADD = average daily dose ( mg/ kg/ day); SR0 = soil residue on day " 0" ( 0.0022 µ g/ g); IgR = ingestion rate of soil ( 100 mg/ day); CF1 = weight unit conversion factor to convert the ug of residues on the soil to grams to provide units of mg/ day ( 1E 6 g/ µ g); and BW = body weight ( 15 kg).

and SRt = TTRt * F * CF2 Where:

TTRt = turf transferable residue on day " 0" ( µ g/ cm2); F = fraction of ai available in uppermost cm of soil ( 1 fraction/ cm); and CF2 = volume to weight unit conversion factor to convert the volume units ( cm3) to weight units for the SR value ( U. S. EPA, 1992) ( 0.67 cm3/ g soil).

Incidental Ingestion of Granules from Pesticide Treated Residential Areas ( toddler)

The approach used to calculate exposures that are attributable to granule ingestion is:

ADD = ( IgR * F * CF1)/ BW Where:

ADD = average daily dose ( mg/ kg/ day); IgR = ingestion rate of soil ( 0.3 g/ day); F = fraction of ai in dry formulation ( unitless); CF1 = weight unit conversion factor to convert the g units in the ingestion rate value to mg for the daily exposure ( 1000 mg/ g); and BW = body weight ( 15 kg).

Dermal Exposure from Treated Ornamental Gardens ( adult and youth)

The approach used to calculate the dermal exposures that are attributable to exposure from contacting treated gardens is: Page 88 of 91 ADD = ( DFR0 * ET * TC * CF1) / BW Where: ADD = average daily dose ( mg/ kg/ day); DFRt = dislodgeable foliar residue on day " 0" ug/ cm2 ); ET = exposure time ( 0.67 hr/ day for adults and 0.33 hr/ day for youths); TC = transfer coefficient ( 10,000 cm2/ hr for adults and 5,000 cm2/ hr for toddlers); CF1 = weight unit conversion factor to convert ug units to mg for the daily exposure ( 0.001 mg/ ug) BW = body weight ( 70 kg for adults and 39 kg for youths).

Dermal Exposure from Golfing on Treated Golf Course Turf( adult and youth)

The approach used to calculate the dermal exposures that are attributable to exposure from contacting treated golf course turf is:

ADD = ( DFR0 * ET * TC * CF1) / BW Where: ADD = average daily dose ( mg/ kg/ day); DFRt = dislodgeable foliar residue on day " 0" ( ug/ cm2 ); ET = exposure time ( 4 hr/ day for adults and youths); TC = transfer coefficient ( 500 cm2/ hr for adults and youths); CF1 = weight unit conversion factor to convert ug units to mg for the daily exposure ( 0.001 mg/ ug) BW = body weight ( 70 kg for adults and 39 kg for youths).

Noncancer Risk Summary: All of the noncancer risk calculations for the various residential triadimefon assessments are included in the appendices.

HED has addressed residential postapplication exposures to triadimefon using the standard set of scenarios that are prescribed in current guidance. There are many issues associated with the development of these scenarios and, in general, residential exposure methods. Readers should refer to the guidance documents that are presented above for further information concerning the development of scenarios for residential exposure assessment purposes. The uncertainty factors are similar to those applied to the residential handler assessments described above ( i. e., 1,000 for short term and intermediate term exposures).

Risk Summary:

Adults Table 17 presents the postapplication MOE values calculated for adults after lawn and home garden applications of triadimefon. For the residential golfer scenarios, short term MOEs are > 1,000 on the day of application. However, short term MOEs are < 1,000 on the day of Page 89 of 91 application for residential turf/ high contact activities and mowing, and home garden scenarios.

Youths were considered in the home garden, residential turf/ mowing, and golfer scenarios. Short term MOEs for these youth children were < 1,000 for all of the scenarios considered except for golfing. Table 18 below summarizes the postapplication MOE values calculated for youths after applications of triadimefon.

Risks ( MOEs) to toddlers were calculated for postapplication risks following the application of triadimefon to home lawns. Table 19 summarizes the risk assessment for toddlers. Page 90 of 91 Only one scenario, incidental soil ingestion, had MOEs > 1000. Short term MOEs were < 1000 for residential turf/ high contact activities, hand to mouth activities, object to mouth activities, and incidental ingestion of granules/ pellets.

Table 20 presents a summary of the combined MOE estimates. Combined these scenarios are a conservative screening level assessment that is driven by the handto mouth scenario.

The combined risk assessment for exposures to toddlers following home lawn applications was calculated:

Combined MOE = NOAEL / ( ADD hand to mouth + ADD object to mouth + ADD incidental soil ingestion + ADD dermal ) Page 91 of 91 Table 20: Triadimefon Residential Scenarios for Combined Risk Estimates Postapplication Exposure Scenario Margins of Exposure ( MOEs) ( UF= 100)

3.2.5 Summary of Residential Postapplication Risk Concerns and Data Gaps HED considered a number of exposure scenarios for products that can be used in the residential environment representing different segments of the population including toddlers, youth aged children, and adults. Short term noncancer MOEs were calculated for all scenarios. Cancer risks were not calculated, since no toxicological endpoint for cancer was selected. In residential settings, HED does not use restricted entry intervals or other mitigation approaches to limit postapplication exposures, because they are viewed as impractical and not enforceable. As such, risk estimates on the day of application are the key concern.

In the assessment for residential postapplication exposure and risk, there are a number of risk concerns for triadimefon as it is currently used in a residential environment.

3.2.6 Recommendations for Refining Residential Postapplication Risk Assessments In order to refine this residential assessment, data on actual use patterns including rates, timing, and the kinds of tasks performed are required to better characterize triadimefon risks.

SUPPLEMENTARY INFORMATION:

Authority for This Rulemaking

    The FAA's authority to issue rules regarding aviation safety is
found in Title 49 of the United States Code. Subtitle I, Section 106
describes the authority of the FAA Administrator. Subtitle VII,
Aviation Programs, describes in more detail the scope of the agency's
authority. This rulemaking is promulgated under the authority described
in Subtitle VII, Part A, Subpart I, Section 40103. Under that section,
the FAA is charged with prescribing regulations to assign the use of
the airspace necessary to ensure the safety of aircraft and the
efficient use of airspace. This regulation is within the scope of that
authority as it would modify Class D airspace and establish Class E
airspace to support IFR and VFR operations at Bradshaw Army Airfield,
Camp Pohakuloa, HI.

Comments Invited

    The FAA invites interested persons to participate in this
rulemaking by submitting written comments, data, or views. Comments are
specifically invited on the overall regulatory, aeronautical, economic,
environmental, and energy-related aspects of the proposal. The most
helpful comments reference a specific portion of the proposal, explain
the reason for any recommended change, and include supporting data. To
ensure the docket does not contain duplicate comments, commenters
should submit only one time if comments are filed electronically, or
commenters should send only one copy of written comments if comments
are filed in writing.
    The FAA will file in the docket all comments it receives, as well
as a report summarizing each substantive public contact with FAA
personnel concerning this proposed rulemaking. Before acting on this
proposal, the FAA will consider all comments it receives on or before
the closing date for comments. The FAA will consider comments filed
after the comment period has closed if it is possible to do so without
incurring expense or delay. The FAA may change this proposal in light
of the comments it receives.
    Privacy: In accordance with 5 U.S.C. 553(c), DOT solicits comments
from the public to better inform its rulemaking process. DOT posts
these comments, without edit, including any personal information the
commenter provides, to www.regulations.gov, as described in the system
of records notice (DOT/ALL-14 FDMS), which can be reviewed at
www.dot.gov/privacy.

Availability of Rulemaking Documents

    An electronic copy of this document may be downloaded through the
internet at www.regulations.gov. Recently published rulemaking
documents can also be accessed through the FAA's web page at
www.faa.gov/air_traffic/publications/airspace_amendments/.
    You may review the public docket containing the proposal, any
comments received and any final disposition in person in the Dockets
Operations office (see ADDRESSES section for address, phone number, and
hours of operations). An informal docket may also be examined during
normal business hours at the Northwest Mountain Regional Office of the
Federal Aviation Administration, Air Traffic Organization, Western
Service Center, Operations Support Group, 2200 S 216th Street, Des
Moines, WA 98198.

Incorporation by Reference

    Class D and E5 airspace designations are published in paragraphs
5000 and 6005, respectively, of FAA Order JO 7400.11, Airspace
Designations and Reporting Points, which is incorporated by reference
in 14 CFR 71.1 on an annual basis. This document proposes to amend the
current version of that order, FAA Order JO 7400.11H, dated August 11,
2023 and effective September 15, 2023. These updates would be published
in the next update to FAA Order JO 7400.11. That order is publicly
available as listed in the ADDRESSES section of this document.
    FAA Order JO 7400.11H lists Class A, B, C, D, and E airspace areas,
air traffic service routes, and reporting points.

The Proposal

    The FAA is proposing an amendment to 14 CFR part 71 that would
modify the Class D airspace and establish Class E airspace extending
upward from 700 feet above the surface at Bradshaw Army Airfield, Camp
Pohakuloa, HI.
    The Class D surface area does not sufficiently contain IFR arrival

operations between the surface and 1,000 feet above the surface on the
Area Navigation (RNAV) (Global Positioning System [GPS]) Runway (RWY) 9
approach. A northwest extension to the Class D lateral boundary should
be added to appropriately contain the point at which an arriving
aircraft is expected to descend to below 1,000 feet above the surface
during the procedure.
    The Class D surface area does not sufficiently contain IFR
departure operations between the surface and the base of adjacent
controlled airspace when departing on the RWY 9 obstacle departure
procedure (ODP). A southwest extension to the Class D lateral boundary
should be added to appropriately contain departing aircraft until
reaching the next adjacent airspace.
    Restricted Area-3103 overlaps the Class D and proposed Class E
airspace. Verbiage should be added to the Class D legal description to
exclude the airspace when it is active.
    Class E airspace extending upward from 700 feet above the surface
does not exist at the airport but must be established to accommodate
transitioning aircraft to/from the terminal or enroute environment by
containing arriving IFR operations below 1,500 feet above the surface
and departing IFR operations until they reach 1,200 feet above the
surface. Class E airspace extending upward from 700 feet above the
surface should be established within a 6-mile radius of the airport
with a westward extension to appropriately contain IFR operations at
the airport.
    Finally, the FAA proposes administrative modifications to the
airport's legal description. The city name on line one of the Class D
legal description text header should be updated to read ``Camp
Pohakuloa'' to match the FAA's database. The airport name on line two
of the Class D legal description text header should be updated to read
``Bradshaw Army Airfield, HI'' to match the FAA's database. The
geographic coordinates located on line three of the Class D legal
description text header should be updated to match the FAA's database.
The Class D legal description should be updated to replace the outdated
use of the phrases ``Notice to Airmen'' and ``Airport/Facility
Directory.'' These phrases should read ``Notice to Air Missions'' and
``Chart Supplement,'' respectively, to align with the FAA's current
nomenclature.

Regulatory Notices and Analyses

    The FAA has determined that this proposed regulation only involves
an established body of technical regulations for which frequent and
routine amendments are necessary to keep them operationally current.
It, therefore: (1) is not a ``significant regulatory action'' under
Executive Order 12866; (2) is not a ``significant rule'' under DOT
Regulatory Policies and Procedures (44 FR 11034; February 26, 1979);
and (3) does not warrant preparation of a regulatory evaluation as the
anticipated impact is so minimal. Since this is a routine matter that
will only affect air traffic procedures and air navigation, it is
certified that this proposed rule, when promulgated, will not have a
significant economic impact on a substantial number of small entities
under the criteria of the Regulatory Flexibility Act.

Environmental Review

    This proposal will be subject to an environmental analysis in
accordance with FAA Order 1050.1F, ``Environmental Impacts: Policies
and Procedures'' prior to any FAA final regulatory action.

SUPPLEMENTARY INFORMATION:

I. What information is EPA particularly interested in?

    Pursuant to section 3506(c)(2)(A) of PRA, EPA specifically solicits
comments and information to enable it to:
    1. Evaluate whether the proposed collection of information is
necessary for the proper performance of the functions of the Agency,
including whether the information will have practical utility.
    2. Evaluate the accuracy of the Agency's estimates of the burden of
the proposed collection of information, including the validity of the
methodology and assumptions used.
    3. Enhance the quality, utility, and clarity of the information to
be collected.
    4. Minimize the burden of the collection of information on those
who are to respond, including through the use of appropriate automated
electronic, mechanical, or other technological collection techniques or
other forms of information technology, e.g., permitting electronic
submission of responses. In particular, EPA is requesting comments from
very small businesses (those that employ less than 25) on examples of
specific additional efforts that EPA could make to reduce the paperwork
burden for very small businesses affected by this collection.

II. What should I consider when I prepare my comments for EPA?

    You may find the following suggestions helpful for preparing your
comments:
    1. Explain your views as clearly as possible and provide specific
examples.
    2. Describe any assumptions that you used.
    3. Provide copies of any technical information and/or data you used
that support your views.
    4. If you estimate potential burden or costs, explain how you
arrived at the estimate that you provide.
    5. Provide specific examples to illustrate your concerns.
    6. Offer alternative ways to improve the collection activity.
    7. Make sure to submit your comments by the deadline identified
under DATES.

Register citation.

III. What information collection activity or ICR does this action apply
to?

    Affected entities: Entities potentially affected by this ICR are
persons engaged in selling, purchasing, or leasing certain residential
dwellings built before 1978, or who are real estate agents representing
such parties.
    Title: Residential Lead-Based Paint Hazard Disclosure Requirements.
    ICR numbers: EPA ICR No. 1710.06, OMB Control No. 2070-0151.
    ICR status: This ICR is currently scheduled to expire on March 31,
2011. An Agency may not conduct or sponsor, and a person is not
required to respond to, a collection of information, unless it displays
a currently valid OMB control number. The OMB control numbers for EPA's
regulations in title 40 of the Code of Federal Regulations (CFR), after
appearing in the Federal Register when approved, are listed in 40 CFR
part 9, are displayed either by publication in the Federal Register or
by other appropriate means, such as on the related collection
instrument or form, if applicable. The display of OMB control numbers
for certain EPA regulations is consolidated in 40 CFR part 9.
    Abstract: Section 1018 of the Residential Lead Based Paint Hazard
Reduction Act of 1992 (42 U.S.C. 4852d) requires that sellers and
lessors of most residential housing built before 1978 disclose known
information on the presence of lead based paint and lead based paint
hazards, and provide an EPA approved pamphlet to purchasers and renters
before selling or leasing the housing. Sellers of pre-1978 housing are
also required to provide prospective purchasers with ten days to
conduct an inspection or risk assessment for lead based paint hazards
before obligating purchasers under contracts to purchase the property.
The rule does not apply to rental housing that has been found to be
free of lead-based paint, zero-bedroom dwellings, housing for the
elderly, housing for the handicapped, or short term leases. The
affected parties and the information collection-related requirements
related to each are described below:
    1. Sellers of pre-1978 housing must attach certain notification and

disclosure language to their sales/leasing contracts. The attachment
lists the information disclosed and acknowledges compliance by the
seller, purchaser, and any agents involved in the transaction.
    2. Lessors of pre-1978 housing must attach notification and
disclosure language to their leasing contracts. The attachment, which
lists the information disclosed and acknowledges compliance with all
elements of the rule, must be signed by the lessor, lessee and any
agents acting on their behalf. Agents and lessors must retain the
information for three years from the completion of the transaction.
    3. Agents acting on behalf of sellers or lessors are specifically
required by section 1018 to comply with the disclosure regulations
described in this paragraph.
    Responses to the collection of information are mandatory (see 40
CFR part 745, subpart F, and 24 CFR part 35, subpart H). Respondents
may claim all or part of a notice confidential. EPA will disclose
information that is covered by a claim of confidentiality only to the
extent permitted by, and in accordance with, the procedures in TSCA
section 14 and 40 CFR part 2.
    Burden statement: The annual public reporting and recordkeeping
burden for this collection of information is estimated to average about
0.18 hours per response. Burden means the total time, effort, or
financial resources expended by persons to generate, maintain, retain,
or disclose or provide information to or for a Federal agency. This
includes the time needed to review instructions; develop, acquire,
install, and utilize technology and systems for the purposes of
collecting, validating, and verifying information, processing and
maintaining information, and disclosing and providing information;
adjust the existing ways to comply with any previously applicable
instructions and requirements which have subsequently changed; train
personnel to be able to respond to a collection of information; search
data sources; complete and review the collection of information; and
transmit or otherwise disclose the information.
    The ICR provides a detailed explanation of this estimate, which is
only briefly summarized here:
    Estimated total number of potential respondents: 39,124,000.
    Frequency of response: On occasion.
    Estimated total average number of responses for each respondent:
1.0.
    Estimated total annual burden hours: 6,937,330 hours.
    Estimated total annual costs: $126,120,374. This includes an
estimated burden cost of $126,120,374 and an estimated cost of $0 for
capital investment or maintenance and operational costs.

 IV. Are there changes in the estimates from the last approval?

    There is a decrease of 807,286 hours in the total estimated
respondent burden compared with that identified in the ICR currently
approved by OMB. This decrease reflects changes in the housing market,
namely a gradual reduction in the annual number of real estate sales
and residential property rentals involving target housing subject to
the rule's requirements. This change is an adjustment.

V. What is the next step in the process for this ICR?

    EPA will consider the comments received and amend the ICR as
appropriate. The final ICR package will then be submitted to OMB for
review and approval pursuant to 5 CFR 1320.12. EPA will issue another
Federal Register notice pursuant to 5 CFR 1320.5(a)(1)(iv) to announce
the submission of the ICR to OMB and the opportunity to submit
additional comments to OMB. If you have any questions about this ICR or
the approval process, please contact the technical person listed under
FOR FURTHER INFORMATION CONTACT.
