Chemical Protective Clothing, Suits . Chemical suits are designed as body protection. Even though physical contact with acrylamide powder or liquid is unlikely, chemical suits are an essential part of an employee's personal protective equipment package during specific operations. EPA has advised that the DuPont brand TychemB model (SL) protection suit provides excellent protection against potential acrylamide exposure hazards. The Tychem@ SL suit is a lightweight, comfortable garment specifically designed for easy wear. It has been tested with acrylamide and shows an average normalized breakthrough time in minutes to be greater than 480. If other products offer protection comparable to that of TychemB SL in standardized laboratory testing with acrylamide, these products would be considered effective as well. The specific operations where TychemB SL or comparable chemical suits must be worn include: transferring and mixing chemical grouts into the mixing tanks; cleaning the tanks, lines or packers. The use of such suits is also necessary during all in manhole operations that involve grouting with acrylamide.

TychemB type suits are considered limited use disposable garments. DuPont describes the use characteristics of these garments as follows: "The exact number of wearings cannot be stated without knowledge of the specific end use. However, up to 5 wearings, under controlled conditions through a structured garment inspection program, are not uncommon in light tomoderate non hazardous activities." Once a garment is contaminated or damaged, it should be properly disposed of immediately.

For any other operation in the truck in which TychemB or comparable suits are not required, the employee must be wearing a long sleeved shirt, full length pants and approved footwear as a minimum requirement. Chemical Protective Clothing, Gloves Chemical gloves are designed as protection of the hand, wrist and forearm, and must be used for any operation where chemical grout is present. These operations include transferring and mixing grouts, handling the packer, and all cleaning and testing operations. A suitable glove will exhibit good resistance to acrylamide, and is also important to specify the proper thickness (gauge). When choosing a glove it is important to specify the proper thickness (gauge). At this time, only the 15 mil (0.38 millimeter) Best brand Nitri Solve@ Model 727 has been tested and reported effective for exposure to acrylamide. If other products offer protection comparable to that of the Best Nitri Solve@ Model 727 gloves in standardized laboratory testing with acrylamide, these products would be considered effective as well.

Gloves should cover the wrist and forearm and fit well enough so the employee has freedom of movement. Gloves may be reused if functioning properly and previous chemical exposure was light. Because the use of gloves and the extent of their exposure is unknown it would be prudent to limit their usage to 5 days or less. Gloves that are heavily contaminated should be changed on a more frequent basis. Gloves that are torn or abraded should be changed immediately, and disposed of properly.

Chemical Protective Clothing, Boots Chemical boots are designed to protect the foot, ankle and lower leg, and must be used for any operation where chemical grout is present. These operations include transferring and mixing grouts, handling the packer, cleaning and testing operations, and all in sewer activities. Boots must exhibit good resistance to be effective. Boots should be cleaned on a daily basis if they have come into contact with chemical grout. Boots that are torn or are heavily worn should be replaced immediately.

Leather footwear is prohibited if it can possibly come into contact with chemical grouts. Leather absorbs spills, creating a pathway for exposure and irritation of the feet and ankles. Once leather has become wet and contaminated, the leather remains contaminated even after drying.

Chemical Protective Clothing, Splash Goggles and Safety Glasses Chemical goggles and safety glasses are designed as protection for the eyes. Unvented chemical splash goggles must be worn for any operation where chemical grout is present if a full facepiece respirator is not being worn. Splash goggles provide superior eye protection as compared to safety glasses. Avanti International recommends such splash goggles as Uvex futuraTM brand (model 9301) or comparable goggles that are specifically designed for splash protection.

Damaged or severely scratched goggles must be discarded immediately. Splash goggles should be cleaned on a daily basis.

Safety glasses may be worn for operations other than those listed above. Safety glasses that fully protect the eye should be chosen. Offering the employee a variety of safety glasses that are comfortable for the wearer will support their proper and consistent use. Use and Care of Personal Protective Equipment Properly maintaining and using personal protective equipment is an important step in the safe handling of chemical grouts. General guidelines for PPE use and care are as follows:

l Inspect all PPE before each use.

l NEVER use damaged or contaminated items.

l Wear, store and clean PPE according to manufacturers' guidelines.

l PPE fit is extremely important. If PPE does not fit well, employees tend not to use it, which defeats its basic purpose.

The best equipment in the world will not protect an employee unless it is used correctly and consistently.

Supervisors should recognize the signs that an employee is not properly using the provided PPE or is not following good safety procedures. No employee should be permitted to work independently with any of the chemical grouts until thoroughly and properly trained. The employee must be able to follow the procedures and required precautions.

Employees MUST do their part to support the effective use of PPE, as follows: e Wear clean clothes each workday and wash before re use.

l Shower and wash hair at end of each workday.

l Wash hands and face before eating, drinking or smoking.

l Keep food out of the work area.

l Maintain a clutter free workspace.

l Consult your supervisor if you do not understand how to use or maintain PPE correctly.

Additional Equipment A dual 32 oz., wall mounted eyewash station should be accessible to employees and maintained in good working order.

Recap: PPE as a Protective System Respirators, chemical protective suits, gloves, boots and goggles are all part of an integrated system to assure that operations with chemical grouts are undertaken and completed safely. It is essential that all elements of the employees' PPE system are clean, functioning properly and property fitted. The employee is responsible for determining the status of each piece of his personal protective equipment. All PPE should be inspected before wearing it in an area or situation that may expose the wearer to hazardous chemicals: If any one piece of equipment is in unsatisfactory condition, the employee should not begin operations until the condition is corrected. PPE should be cleaned and inspected at the end of each shift and properly stored for future use. PPE by definition is an employee's last line of defense and should be treated accordingly.

Avanti International has listed specific brands of PPE, including chemical protective clothing, as a convenience. It is the responsibility of each user of Avanti grouting products to determine the type and brand of equipment that is appropriate for their specific work environment. To promote employee safety, however, the equipment selected should provide protection at least equivalent to what the examples cited above would provide. I I I I I I I I I I I I I I I I I I I 4 2 I `2 I I I I I I I I I I I I I I I I I I I Housekeeping Good housekeeping in the work area is as important as the safe handling of chemical grouts. TV/ Grout rigs have very small work areas and should be organized to allow employees the greatest freedom of movement and the ability to perform their jobs in a safe manner. Time allotted to the maintenance of the interior of the truck is as valuable as changing the oil or inspecting the tires.

Employees should become familiar with the checklist provided below and follow it as a minimum daily requirement for their housekeeping duties. The list is not meant to be exhaustive; any site specific or operation specific requirements should be added by the employer as needed. Along with the proper storage location for chemicals being transported, the employees should have designated locations for the disposal of empty containers and bags. Grouting equipment should be washed with clean water to limit accidental exposure from the handling of packers, scoops, mixing paddles, pitchers, cameras, and the hose reel.

Good housekeeping in the cab area of the truck is also important. Employees should refrain from storing food and beverages in the open cab areas of the TV/ Grout rig. Do not eat or drink anywhere in the TV/ Grout rig. Smoking should never be permitted in a TV/ Grout rig.

Daily Housekeeping Checklist Clean work area often and maintain it in good condition. Make sure water tank is full. This is important not only for making more grout, but it can be used for clean up and also can be used in case of an emergency. Mop the floors, wash down outside of grout tanks, and wash hose reel and packers with fresh water, making sure that excess water is directed into a sanitary sewer. Wash tools used to work on pumps, packers and hoses with fresh water, making sure that excess water is directed into a sanitary sewer. Immediately wash down any spills, that cannot be collected or gelled. Secure door to control room during the mixing process. When transporting the Triethanolamine (Cat T), it must always be kept away from either Ammonium Persulfate (AP) or Sodium Persulfate (SP). Seal all chemical containers immediately after use. Secure all chemical containers so as not to shift during transit. Always store chemicals in original containers. Remove empty containers from the TV/ Grout rig and d& pose of properly. Operator should clean steering wheel to prevent cross contamination. Assistant should inspect grouting system for leaks while in use and repair as necessary. Chemical protective clothing (CPC) should be cleaned thoroughly at the end of each shift. CPC should be stored in clean plastic bags away from the chemicals. CPC should be stored outside of the control room. CPC should be thoroughly inspected before being used.

Shipping Information See Page 35. Mixing Instructions for AV IOO Chemical Grout (AM Powder) AV 100 AM Conventional Mix (11.6% Solids, approx. 25 Second Gel Time at 72° F)

Before mixing procedures begin, the operator must determine 1) the necessary gel strength and gel time required for the specific application, 2) the availability of all necessary grout components, and 3) that all safety equipment is present and in good working order.

Personal Protective Equipment (PPE) During transfer/ mixing operations, the minimum PPE consists of a cartridge respirator full facepiece type, a TychemB brand or equivalent chemical suit, and gloves and boots that meet the descriptions in Chapter 2.

Product Information A single 55 pound bag of AV 100 AM Acrylamide Monomer powder, mixed with 64 ounces (2.75 pounds) of Methylenebisacrylamide (MBA) yields a 60 gallon batch of 11.5% (by weight) strength acrylamide grout. For best results, these grouts should be blended at concentrations of 10% or greater. Concentrations above 10% are favored for high strength gel applications or to handle dilution of more than 50% prior to gelation.

Mixing Instructions (Conventional Mix)

Tank A (Grout Tank) Tank B (Catalyst Tank)

l AV 100 powder: 1 bag l AV 102 AP: 5 Ibs. (60 ounces by . MBA emulsion: 64 ounces by volume volume)

l Water: Add enough water to make . AV 101 Cat T: 70 ounces by volume (5 Ibs.) a 30 gallon batch . Water: Add enough water to make a 30 gallon batch.

The above conventional mixture can be modified to meet your specific application.

The Methylenebisacrylamide (AV 100 MBA) is an emulsion that is a required grout compound. Always use the complete container for each batch. The AV 100 MBA is always added to the grout side tank.

The Triethanolamine (AV 101 Cat T+) is a liquid that is a required grout compound and can be increased from a minimum of 35 ounces by volume (. 5% by weight, 2.5 Ibs.) to a maximum of 175 ounces by volume (2.5% by weight, 12.5 Ibs). Using more than 175 ounces by volume is not recommended, as it results in too fast a gel time. The AV 101 Cat T is always added into the same tank as the grout.

The Ammonium Persulfate (AV 102 AP) is a powder that is a required grout compound and can be increased from 5 pounds (1% by weight, 60 ounces by volume) to a maximum of 15 pounds (3% by weight, 180 ounces by volume). The AV 102 is added to the catalyst tank.

Sodium Persulfate (AV 103 SP) is a powder that may be used in place of Ammonium .Persulfate (AV 102 AP), although Avanti International considers AV 102 AP to be a more effective product for mixing AV 100 grouts. The same amount of AV 103 SP is used when replacing AV 102 AP. The AV 103 is added to the catalyst tank. Storage and disposal of AV 103 are addressed in the AV 118 section. I I I I I I I I I I I I I I I I I I I 8 Grout Transfer Method The operator and staff are at the highest risk for exposure to acrylamide when the powdered AV 100 is transferred from the bag into the grout tank. Every precaution should be taken to assure that the operator and other crewmembers are not exposed to the acrylamide powder either in the air or spilled in the vehicle. The following procedure, accompanied by the wearing of appropriate PPE, effectively reduces the possibility of chemical exposure.

PPE Steel toed boots and protective gloves and goggles should be worn before moving the drum containing AV 100 powder from storage. During the transfer/ mixing process a cartridge respirator, appropriate boots and a TychemB brand or comparable chemical suit are required. Gloves approved for use with acrylamide must be worn in order to keep the liquid or powder from coming into contract with the skin. Avanti International highly recommends the use of a full face piece respirator during transfer/ mixing operations.

Procedure Keep the bag of AV 100 intact whenever possible. Fill grout tank with approximately 15 gallons of water before introducing the AV 100 MBA or AV 100 powdered grout. Add 64 ounces of AV 100 MBA emulsion to grout side tank. Add small amount of water to container, rinse to remove any residue, mix all thoroughly. Do not let AV 100 MBA contact skin. Place the neck of the AV 100 powdered grout bag under the surface of the water as the grout is being poured into the grout tank. It is extremely important to take care that no powder is released into the air or spilled during transfer. Empty the bag of AV 100 powdered grout as completely as possible and roll the bag from bottom to top before carefully removing from the grout tank. Immediately wrap up the bag and place it in another bag so that no powder or liquid on the grout bag is released inside the vehicle. Add 70 fluid ounces by volume (5 Ibs.) of liquid AV 101 Cat T+ to the grout tank. Add 5 Ibs. (60 fluid ounces by volume) of powder AV 102 to the catalyst tank. Fill both tanks to the 30 gallon level with water.

Properly dispose of the bags and empty MBA containers, as described earlier in this chapter. The empty bags and containers must not be used for any other purposes.

Field Conditions The temperature of the water in the tanks has a large impact on grout gel times. Therefore, water temperature should be measured throughout the day to help determine desired grout gel times. Since the gel time is greatly reduced with increasing temperatures, cup tests to monitor gel times should be conducted. As a general rule of thumb, gel time is reduced by one half for every 10° F rise in temperature. Water temperatures can vary dramatically between early morning and late afternoon. Trucks parked overnight or through a weekend can reach temperatures as high as 150° F.

The grout side tank should not be exposed to direct sunlight as UV rays can accelerate polymerization. Optional Additives I There are several additives that can modify the behavior of the grout being used.

Ethylene Glycol, Liquid (AV 105) Amount: Maximum of 2.5 gallons per tank. I Add equal amounts to both tanks, replaces water. Finish by filling tanks with water to 30 gallon I line. Tanks should not exceed 30 gallon fill line. Result: Enhances grouts ability to undergo freezing and dehydration. Lowers freezing temperature of the solution. I Icosetilatex, Liquid (AV 257) Amount: 2 to 3 gallons. I Add to grout side only, replaces water. Finish by filling tank with water to 30 gallon line. Tank should not exceed 30 gallon fill line. Result: increases compressive and tensile strength, also increases viscosity. I Potassium Ferricyanide, Powder (KFe) Amount: Very small amount, less than `I4 teaspoon to start. Add to grout side tank. Result: Extends gel times.

Norosac, Powder (AC SOW A) Amount: 3.2 ounces by weight. This is equal to 5 0~ in an 8 fluid ounce measuring cup. Add to grout side tank. Results: Slows new growth of roots in the sewer joints.

Shipping Information See Page 35. Mixing Instructions for AV IOO Chemical Grout (Liquid) Conventional Mix (10% Solids, approx. 25 Second Gel Time at 72° F)

Before mixing procedures begin, the operator must determine 1) the necessary gel strength and gel time required for the specific application, 2) the availability of all necessary grout components, and 3) that all safety equipment is present and in good working order.

Personal Protective Equipment (PPE) During transfer/ mixing operations, the minimum PPE consists of a cartridge respirator full facepiece type, a TychemB brand or equivalent chemical suit, and gloves and boots that meet the descriptions in Chapter 2.

Product Information The 15gallon drum contains approximately 14 gallons of liquid grout, the equivalent of a single 50 pound bag of AV 100 powder, including MBA, dissolved in water.

Most manufacturers of equipment have standardized by providing two 30 gallon chemical tanks. When properly mixed, one drum of liquid AV 100 acrylamide grout results in a 10% (by weight) strength grout solution of 60 gallons. Using two drums of AV 100 acrylamide grout results in a 20% (by weight) strength grout solution of 60 gallons.

One 15gallon drum will make a 60 gallon batch of grout. For best results, grouts should be blended at concentrations of 10% or greater. Concentrations above 10% are favored for highstrength gel applications or to handle dilution of more than 50% prior to gelation.

Mixing Instructions (Conventional mix)

Tank A (Blue Grout Tank) . AV 100 liquid: 1 drum l AV 101 Cat T: 70 ounces by volume (5 Ibs.)

l Water: Add enough water to make a 30 gallon batch.

The above conventional mixture can be mo I Tank B (Red Tank)

l AV. I02 AP: 5 Ibs. (60 ounces by volume)

l Water: Add enough water to make a 30 gallon batch ed to meet your specific application.

The Triethanolamine (AV 101 Cat T) is a liquid that is a required grout component and can be increased from a minimum of 35 ounces by volume (5% by weight, 2.5 Ibs.) to a maximum of 175 ounces by volume (2.5% by weight, 12.5 Ibs). Using more than 175 ounces by volume is not recommended. The AV 101 Cat T is always added into the same tank as the grout.

The Ammonium Persulfate (AV 102 AP) is a powder that is a required grout component and can be increased from 5 pounds (1% by weight, 60 ounces by volume) to a maximum of 15 pounds (3% by weight, 180 ounces by volume).

Sodium Persulfate (AV 103 SP) is a powder that may be used in place of Ammonium Persulfate (AV 102 AP). The same amount of AV 103 SP is used when replacing AV 102 AP. Avanti International prefers AV 102 AP when mixing AV 100 grouts. Grout Transfer Method Avanti highly recommends the use of a pump, hand or electric, to transfer liquid grout from the l5 gallon drum into the grout tank. Using a pump minimizes worker exposure to grout spills or splashes. Another benefit of using a pump is that the empty grout drum will be rinsed and ready for disposal or recycling; that can be accomplished by adding the solution mix water to the empty grout drum and pumping it in the grout tank. The following procedure, accompanied by the wearing of appropriate PPE, effectively reduces the possibility of chemical exposure.

PPE Steel toed boots; and protective gloves and goggles should be worn before moving the drum containing AV 100 liquid from storage. During the transfer/ mixing process a cartridge respirator, appropriate boots and a TychemB brand or equivalent chemical suit are required. Gloves approved for use with acrylamide must be worn in order to keep the liquid from coming into contract with the skin. Avanti International highly recommends the use of a full face piece respirator during transfer/ mixing operations.

Procedure A power lift or two men should be used when lifting the 130 pound grout drum into the back of the grout truck. Place the 15gallon grout drum within several'feet of the grout side mixing tank. Using a bung tool, remove the 2 inch bung, being careful not to let surface contamination enter the drum. Caution: Wetted pump parts must be plastic or stainless steel only. Place the hand pump suction tube into the drum and secure by completely threading the down tube into the drum. Place pump discharge hose into grout tank extending the hose at least 113 of the way into the tank. Caution must be used to make sure the hose does not slip out of the tank during transfer. Maintain a steady flow while pumping grout. When the grout drum is empty, add 5 to 7 gallons of water to grout drum through the small l inch bung. Pump water from the grout drum into the grout tank. This process effectively rinses the drum. Remove hose from the grout tank. Remove pump from the grout drum. Wash and flush the pump, and hoses. Store pump and hoses in a clean environment. Properly dispose of drum or call a drum recycling company. This empty drum must not be used for any other purpose. Add 70 fluid ounces by volume (5 Ibs.) of liquid AV 101 Cat T+ to the grout tank. Add 5 Ibs. (60 fluid ounces by volume) of powder AV 102 to the catalyst tank. Fill both tanks to the 30 gallon level with water.

19 @z&. 7 7 Field Conditions The temperature of the water in the tanks has a very large impact on grout gel times. Since the gel time is greatly reduced with increasing temperatures, gel times should be determined throughout the day. As a general rule of thumb, gel time is reduced by one half for every 10° F rise in temperature. Therefore, water temperature should be measured to help determine desired grout gel times. Water temperatures should also be monitored throughout grouting operations as temperatures can vary dramatically between early morning and late afternoon. Trucks parked overnight or through a weekend can reach temperatures as high as 150° F.

The grout side tank should not be exposed to direct sunlight as UV rays can accelerate polymerization.

Optional Additives There are several additives that can modify the behavior of the grout being used.

Ethylene Glycol, Liquid (AV 105) Amount: Maximum of 2.5 gallons per tank. Add equal amounts to both tanks, replaces water. Finish by filling tanks with water to 30 gallon line. Tanks should not exceed 30 gallon fill line. Result: Enhances grout's ability to undergo freezing and dehydration. Lowers freezing temperature of the solution.

Icoset/ Latex, Liquid (AV 257) Amount: 2 to 3 gallons. Add to grout side only; replaces water. Finish by filling tank with water to 30 gallon line. Tank should not exceed 30 gallon fill line. Result: Increases compressive and tensile strength, also increases viscosity.

Potassium Ferricyanide, Powder (KFe) Amount: Very small amount, less than % teaspoon to start. Add to grout side tank. Result: Extends gel times.

Appendix B:  Occupational Handler Exposure Data and Risk Calculations FOR OCCUPATIONAL AND RESIDENTIAL EXPOSURES TO Mefluidide

  SEQ CHAPTER \h \r 1 APPENDIX A -1

STANDARD FORMULAS USED FOR

CALCULATING

OCCUPATIONAL AND RESIDENTIAL

EXPOSURES TO Mefluidide

A.  Introduction

This document is a summary of the formulas used to calculate occupational and residential exposures to mefluidide.   These formulas and a basic description of how they are used were taken from References A through E.  These references also contain more detailed information on the rationale behind these formulas.

B.  Occupational Handler/Applicator Exposures

	The basic rationale for these formulas is that the daily exposure is the product of the amount of active ingredient (a.i.) handled per day times a unit exposure value.  The amount of ai handled per day is the product of the application rate times the area treated.  For example, if 1.0 lb/acre of MEFLUIDIDE were applied to 80 acres in one day, the amount of mefluidide handled that day would be 80 lbs.  The unit exposure value is the amount of exposure that results from handling a given amount of active ingredient by a certain method while using certain PPE.  For example, the inhalation unit exposure value for open mixing and loading of liquids is 1.0 ug per pound of ai handled.  In this example, the daily exposure would be 80 lbs ai handled times 1.0 ug unit exposure per pound of ai handled which equals 80 ug per day.  The daily absorbed dose (mg/kg BW) is calculated from the exposure by converting the exposure from ug into mg, multiplying the exposures times an absorption factor (usually 1.0 for inhalation) and dividing the result by the body weight (70 kg).  In this example the daily dose is (80 ug/day * 0.001 mg/ug *1.0)/70 kg which equals 0.0011 mg/kg/day.

Daily inhalation exposure is calculated:

Daily inhalation exposure = Unit exposure x Application rate x Area Treated x Conversion Factor (1.0E-3)                        (mg/kg/day)

Where:

Unit exposure	=	(ug/lb ai handled) derived from PHED or ORETF Study Data

Application rate	=	lb ai per acre or gallon of spray solution; and

Daily treatment	=	acres or gallons applied per day).

Absorbed Daily Dose is calculated:

Absorbed daily inhalation dose = (Daily  inhalation exposure x absorption factor) / body weight

(mg/kg/day)                                     (mg/day)                                     (unitless)               (kg)

[Note: an absorption factor of 1.0 was used for inhalation exposures.]

	Once the absorbed daily doses are calculated, the Margins of Exposure (MOEs) can be calculated as shown below:

Margin of Exposure is calculated:

MOE (unitless)  =   NOAEL (mg/kg/day)  /  Dose (mg/kg/day)

	The target MOE is 100 for occupational handlers. Scenarios with MOEs greater than the target MOEs do not exceed the Agency’s level of concern.

C.  Residential Handler Exposures

	Residential handler exposures are calculated in the same manner as described above for occupational handlers, however, there are a few differences in the assumptions used.   These differences are described in References B and C and include the following:

*PPE such as respirators are not worn.

*The areas treated are much smaller.

D.  Residential Post Application Exposure on Treated Turf

	The SOPs For Residential Exposure Assessment (Reference B) define three incidental oral pathways that apply to post application toddler exposure on treated turf.  The SOPs and the associated pathways are presented below:

∙	Dose from hand-to-mouth activity from treated turf calculated using SOP 2.3.2:

	Residues ingested from a child touching turf and then putting their hands in their mouth.

∙	Dose from object-to-mouth activity from treated turf calculated using SOP 2.3.3:

	Residues ingested from a child mouthing a handful of treated turf); and

∙	Dose from soil ingestion activity from treated turf calculated using SOP 2.3.4:

	Residues from a child touching treated soil and then putting their hands in their mouth.

	The algorithms used for each type of dose calculation are presented on the following pages.

Exposures from Hand to Mouth Behavior on Treated Turf:

The following formula is used to calculate the incidental oral ingestion exposures from to hand-to-mouth behavior on treated turf (SOP 2.3.2).

PDR = TTR * (SE/100) * SA * Freq * Hours * (1 mg/1000 ug)

	where:

PDR		=	potential dose rate from hand-to-mouth activity (mg/day);

TTR		=	Turf Transferable Residue (µg/cm2);

SE		=	saliva extraction factor (50%);

SA		=	surface area of the hands (20 cm2);

Freq		=	frequency of hand-to-mouth events (20 events/hour); and

Hours	=	exposure duration (2 hours).

	When used for hand to mouth exposures, the TTR value is based upon the default assumption of 5 percent of the application rate and not the TTR study .

The formula for calculating the Day 0 TTR value is given below:

TTR = 	Application Rate * F * CF1 * CF2 * CF3

Where:

Application Rate	=	lbs ai/acre

F			= 	fraction of applied ai that is available for hand to mouth exposure (5 percent)

CF1			= 	1.0 lb ai/acre equals 2.3 x 10-5 lbs ai per ft2

CF2			= 	4.54 x 108 ug/lb

CF3			= 	0.00108 ft2/cm2

Note:  CF1 * CF2 * CF3 = 11.23

Exposures from Object to Mouth Behaviors on Treated Turf

The following formula is used to calculate exposures from object-to-mouth behavior on treated turf that is represented by a child mouthing on a handful of turf (SOP 2.3.3):

PDR = TTR * IGR * (1mg/1000ug)

where:

PDR		=	potential dose rate from mouthing activity (mg/day);

TTR		=	Turf Transferable Residue where dissipation is based on TTR study and the 0-day value is based on the 20% initial transferability factor (µg/cm2); and

IgR		=	ingestion rate for mouthing of grass per day (25 cm2/day).

When used for object to mouth exposures, the TTR value is based upon the default assumption of 20 percent of the application rate .

Exposures from Soil Ingestion on Treated Turf

	The following formula is used to calculate exposures from soil ingestion (SOP 2.3.4):

PDR = SR * IgR * (0.000001 gm/ 1 ug)

Where:

PDR	=	dose from soil ingestion activity (mg/day)

SR	=	Soil Residue where dissipation is based on TTR study and the 0-day value is based on the application rate, 1 cm depth of surface soil, and the density of soil (µg/cm3)

IgR	=	ingestion rate for daily soil ingestion (mg/day)

Where:

SR	=	Application rate * F*11.23*CF4

Where

F = Faction of ai available in the uppermost cm of soil (100%/cm)

1.0 lbs/acre = 11.23 µg/cm2

CF4 = Volume to weight unit conversion factor to convert the volume units (cm3) to weight units for the SR value (0.67 cm3/g soil)

MOE Calculations for Each Pathway

The MOEs are calculated for each individual pathway using the MOE formula:

MOE  =   NOAIL (mg/kg/day / Dose (mg/kg/day)

MOEs Calculations for All of the Pathways Combined

The dose from each incidental oral pathway was combined into a total dose as shown below.

Total Dose = (Hand-to Mouth Dose + Object to Mouth Dose + Soil Ingestion Dose)

The total dose is then used to calculate an MOE as shown above. The target MOE is 100.

SUPPLEMENTARY INFORMATION:

I. Background

    In the Federal Register of June 18, 2014 (79 FR 34759), FDA
announced the availability of a draft guidance for industry entitled
``Internet/Social Media Platforms with Character Space Limitations:
Presenting Risk and Benefit Information for Prescription Drugs and
Medical Devices.'' In that document, FDA requested comments on the
draft guidance, which responds to (among other things) stakeholder
requests for specific guidance. The draft guidance describes FDA's
current thinking on how manufacturers, packers, and distributors of
prescription human and animal drugs and medical devices for human use,
including biological products, that choose to present benefit
information should present both benefit and risk information within
advertising and promotional labeling of their FDA-regulated medical
products on electronic/digital platforms that are associated with
character space limitations, specifically on the Internet and through
social media or other technological venues. The draft guidance
represents FDA's current thinking on specific aspects of FDA's evolving
consideration of social media platforms and other Internet-related
matters. FDA actively continues to review, analyze, and develop
approaches to a variety of topics related to the labeling and
advertising of medical products, including the development of this and
other guidance addressing the use of social media platforms and the
Internet.
    Interested persons were originally given until September 16, 2014,
to submit comments on the draft guidance.

II. Request for Comments

    Following publication of the June 18, 2014, notice, FDA received a
request for additional time to develop meaningful and thoughtful
comments, especially in light of the concurrent comment period with
another draft guidance entitled ``Internet/Social Media Platforms:
Correcting Independent Third-Party Misinformation About Prescription
Drugs and Medical Devices'' published elsewhere in this volume of the
Federal Register.
    FDA has considered the request and will reopen the comment period
for an additional 30 days. The Agency believes that an additional 30
days allows

adequate time for interested persons to submit comments without
significantly delaying the Agency's consideration of these important
issues.

III. How To Submit Comments

    Interested persons may submit either electronic comments regarding
this document to http://www.regulations.gov or written comments to the
Division of Dockets Management (see ADDRESSES). It is only necessary to
send one set of comments. Identify comments with the docket number
found in brackets in the heading of this document. Received comments
may be seen in the Division of Dockets Management between 9 a.m. and 4
p.m., Monday through Friday, and will be posted to the docket at http://www.regulations.gov.

``us,'' or ``our'' is used, we mean EPA. This supplementary information
section is arranged as follows:

I. What Action Is EPA Taking?
II. Under What Authority Is EPA Approving These Delegations?
III. What Is the Effect of These Delegations?
IV. How Can I Get Copies of This Document and Other Related
Information?

I. What Action Is EPA Taking?

    We are notifying the public that pursuant to section 112(1) of the
Clean Air Act (CAA) and 40 CFR 63.92, EPA has approved the IDEM request
to delegate the authority to implement and enforce 40 CFR part 63,
subparts II, CCC, MMMM, PPPP, and DDDDD. IDEM has incorporated these
NESHAPs by reference, unchanged from the federal standards, through
Indiana rules 326 IAC 20-26, 326 IAC 20-29, 326 IAC 20-80, 326 IAC 20-
81, and 326 IAC 20-95, respectively. EPA has also approved the
delegation of the Category I authorities for these NESHAP standards as
set forth at 40 CFR 63.91(g).

II. Under What Authority Is EPA Approving These Delegations?

    Pursuant to section 112(1) of the CAA, a state may develop and
submit to EPA for approval a program for the partial or complete
delegation of section 112 rules. EPA may approve state rules or
programs which either: (1) Implement and enforce section 112 rules as
promulgated by EPA (``straight delegation''); (2) implement and enforce
state rules which adjust section 112 rules; or, (3) implement and
enforce state rules which substitute for section 112 rules. The Federal
regulations governing EPA's approval of state rules or programs under
section 112(1) are located at 40 CFR part 63, subpart E.
    Currently, IDEM has an EPA-approved program for the straight
delegation of NESHAP standards. EPA approved IDEM's program for part 70
and non-part 70 sources on November 14, 1995, (60 FR 57118) and July 8,
1997 (62 FR 36460), respectively. Pursuant to the approved delegation
program, EPA has approved the straight delegation of numerous NESHAP
standards in Indiana (see 62 FR 36460 (7/8/1997), 65 FR 17264 (3/31/
2000), 69 FR 22508 (4/26/2004), and 71 FR 2225 (1/13/2006)). EPA has
also approved rule adjusted NESHAP delegations for subparts X, VVVV,
WWWW (see 71 FR 48923 (8/22/2006) and 71 FR 56971 (9/28/2006)).
    By letter dated February 8, 2007, IDEM requested approval of five
additional `straight delegations' of authority for 40 CFR part 63,
subparts II, CCC, MMMM, PPPP, and DDDDD.

III. What Is the Effect of These Delegations?

    On May 30, 2007, EPA approved IDEM's request to delegate the
authority to implement and enforce 40 CFR part 63, subparts II, CCC,
MMMM, PPPP, and DDDDD, through 326 IAC 20-26, 326 IAC 20-29, 326 IAC
20-80, 326 IAC 20-81, and 326 IAC 20-95. EPA also approved the
delegation of the applicable Category I authorities as set forth at 40
CFR section 63.91(g).
    All notifications, reports and other correspondence required under
these NESHAPs, should be sent to the State of Indiana, rather than to
the EPA, Region 5, in Chicago. Affected sources should send this
information to: Indiana Department of Environmental Management, Office
of Air Quality, 100 North Senate Avenue, Indianapolis, Indiana 46204-
2251.
    Pursuant to Section 112(1)(7) of the CAA, nothing in this
delegation prohibits EPA from enforcing any applicable emission
standard or requirement.
