# Section 1 Purpose and Scope

This document defines the standard operati ng procedure (SOP) for decontamination of personnel and equipment engaged in sampling activities. This SOP serves as a supplement to the project work plan, and the project Health and Safety Plan (HSP). It is intended that these procedures described below be used together with the project work plan, the project HSP, and other SOPs.
The overall objective of the sampling program is to obtain samples that accurately characterize the chemical contamination pr esent at the sampling site. Extraneous contaminant materials can be brought onto the sampling location and/or introduced into the medium of interest during the sampling pr ogram (e.g., by improperly cleaning the split spoon sampler between individual soil samples). Trace quantities of these contaminant materials can consequently be captured in a sample and lead to false positive analytical results, and, ultimately, to an incorrect assessment of the c ontaminant conditions associated with the Site. Decontamination of sampling equipment (e .g., bailers, pumps, tubing, soil and sediment sampling equipment) and field support equipm ent (e.g., drill rigs, vehicles) is therefore required prior to use to ensure that sampling cross-contamination is prevented, and that onsite contaminants are not carried off-site.Page 4 of 8 

# Section 2 Procedure

Equipment and personnel must be thoroughly decontaminated prior to entering the environmental investigation area (exclusion zone). Upon leaving the exclusion zone, all personnel and equipment must be thoroughly dec ontaminated. In addition, decontamination may be necessary from sample site to sample site within the exclusion zone. Proper decontamination of equipment and pers onnel will decrease the potential for cross contamination and reduce adverse health effects.
This procedure describes the decontamination of personnel, soil drilling and sampling equipment, monitoring well installation and samp ling equipment, and tools used during field investigation activities. These procedures w ill remain in place unless modified by the site specific work plan or HSP. 

## 2.1 Equipment List

The following is a list of equipment that may be needed to perform decontamination:
Plastic sheeting Scrub brushes Wash tubs Buckets Scrapers, flat blade Hot water - high-pressure sprayer Disposal drums (55-gallon with secure lids) Sponges or paper towels Alconox/Liquinox detergent (or equivalent) Potable tap water Laboratory-grade deionized water Garden-type water sprayers Isopropyl alcohol Hand soap Hand wipes 

## 2.2 Personnel Decontamination

A temporary personnel decontamination line w ill be set up around each exclusion zone. If contamination is not encountered, a dry decont amination station may be established which consists of discarding of disposable personal protective equipment (PPE).Page 5 of 8 If real-time monitoring instruments indicates th at contamination has been encountered, (i.e., action levels are exceeded requiring an upgrade fr om initial PPE levels), or if the initial PPE is Level B or C, a complete personnel decontamination station will be established.
The temporary decontamination line should provi de space to wash and rinse boots, gloves, and all sampling or measuring equipment and a c ontainer to dispose of used disposable items such as gloves, tape, or tyvek.
The decontamination procedure for field personnel in Level B or C PPE shall include (also see the HSP):

Glove and boot wash in an Alconox solution Glove and boot rinse Duct tape removal Outer glove removal Coverall (Tyvek) removal Respirator or self-contained breathing apparatus (SCBA) removal Inner glove removal 

## 2.3 Sampling Equipment Decontamination

The following steps will be used to decontaminate sampling equipment:

 Personnel will dress in suitable PPE to reduce personal exposure as required by the HSP.

 Sampling equipment will be decontaminated prior to sampling activities, between sample locations, and at the end of sampling activities.

 Gross contamination on equipment will be scraped off at the sampling site.

 Equipment that will not be damaged by water will be placed in a wash tub containing Alconox or equivalent detergent along with tap water and scrubbed with a scrub brush or similar tool.

 Equipment will be rinsed with tap water, then with isopropyl alcohol and then a final rinse with deionized/distilled water.

 Groundwater sampling pumps will be “turned on” to allow detergent, tap water, and deionized/distilled water to cycle through the pump.

 The equipment will be allowed to air dry.

 Equipment that may be damaged by water will be carefully wiped clean using a sponge and detergent water and rinsed with deionized water. Care will be taken to prevent any equipment damage.

 Rinse and detergent water will be replaced with new solutions between borings or sample locations or as determined necessary by the field manager.
Following decontamination, equipment will be pl aced in a clean area or on clean plastic sheeting to prevent cross contamination. If th e equipment is to be transported, it will bePage 6 of 8 covered or wrapped in aluminum foil (prefe rred method), plastic sheeting, or heavy-duty trash bags to minimize potential airborne contamination.
The following guidelines will be followed in the fi eld at all times to ensure sample integrity and to prevent any cross contamination of samples.

 A clean pair of disposable latex gloves will be worn each time a different location is sampled and shall be changed each time the gloves come into contact with a material that has not been properly decontaminated.

 Sample collection activities will proceed from the least contaminated area to the most contaminated area when this information is available. 

## 2.4 Drilling and Heavy Equipment Decontamination

Drilling rigs will be decontaminated at the d econtamination station. The following steps may be used to decontaminate drilling and heavy equipment:

 Personnel will dress in suitable PPE to reduce personal exposure as required by the HSP.

 Drilling and heavy equipment will be decontaminated prior to drilling, between locations, and at the end of drilling.

 Remove as much soil and debris as possible from augers and tools at the borehole or sampling location.

 Equipment that will not be damaged by water, such as drill rigs, augers, drill bits, and shovels, will be sprayed and then rinsed with potable water. Care will be taken to adequately clean the insides of the hollow-stem augers.

 If augers and tools are visibly contaminated, clean tools in large tub so that decontamination water is contained.

 During soil sampling, the split spoon sampler and sample sleeves shall be decontaminated by the field crew and not the drilling contractor.

 After cleaning, place augers and tools on plastic sheeting on the cleaned bed of the support truck or the cleaned auger rack on the drill rig.

 Any decontamination water that was generated during drilling and heavy equipment decontamination shall be placed in 55-gallon drums or other suitable storage tank and the source of the water (i.e., borehole where tools were last used) shall be marked on the drum or tank.
An alternative to the above would be to steam clean auger flights. 

## 2.5 Waste Handling

Any waste generated during decontamination activities will be collected and handled according to the procedures outlined in the project work plan and the SOP for waste handling.Page 7 of 8 

## 2.6 Documentation

Sampling personnel will be responsible for doc umenting the decontamination of sampling and drilling equipment. The documentation will be recorded with waterproof ink in the sampler's field notebook with consecutively numbere d pages. The information entered in the field book concerning decontamination should include the following:
Decontamination personnel Date and start/end times Decontamination observations Weather conditionsPage 8 of 8 

# Section 3 Quality Assurance Requirements

Equipment rinsate samples will be taken of the decontaminated sampling equipment to verify the effectiveness of the decontamination pro cedures. The sampling procedure will include rinsing deionized water through or over a dec ontaminated sampling tool (such as a split spoon sampler or groundwater pump) and collecti ng the rinsate water into the appropriate sample bottles, which will be sent to the labor atory for analysis. The rinsate procedure, including the sample number, will be recorded in the field notebook. The frequency of rinsate sample collection and the laboratory an alysis required are described in the project work plan. The handling and documentation pro cedures of the rinsate sample are described in the Containerizing, Preserving, Ha ndling, and Shipping Samples SOP.c:\cliff\sop8.doc SAMPLING AND ANALYSIS PLAN

# Section 1 Purpose and Scope

This document defines the standard operating procedure (SOP) for the handling of drums (primarily 55-gallon drums) during the Johnston Island site characterization report. This SOP serves as a supplement to the Sampling and Analysis Plan (SAP) that is included in the Work Plan (WP). This document is intended to be used together with the SAP and other SOPs.c:\cliff\sop8.doc 2-1 SOP No. 8 

# Section 2 Hazard Awareness and Regulatory Considerations

2.1 Hazard Awareness

A variety of work site activities may requi re unearthing, moving, lifting, overpacking, or sampling drums. Such activities are inherently hazardous and will always require special health and safety precautions. Drum handling presents numerous serious physical hazards including back injury, crushing, bruising, lacera tion, and severe trauma from mishandling. Drum contents may represent a fire or explos ion hazard or may consist of shock-sensitive or pyrophoric materials. Drum contents may be pre ssurized or be acutely toxic. Contents may be corrosive or irritating or have other toxic effects. Drum handling may, therefore, represent both physical and chemical hazards. 

## 2.2 Personal Protective Equipment (PPE)

The appropriate PPE ensemble for drum ha ndling (and sampling) can vary significantly depending on the particular job conditions. Supp lied air equipment (SCBAs or airlines) may be appropriate respiratory protection for a wi de range of potential exposures. Full face airpurifying respirators may be adequate for ot her situations. Some drums may be safely handled without respiratory prot ection. The types of gloves, coveralls (coated or uncoated), boots, and other PPE can also vary based on hazard evaluation. The selection of the appropriate PPE should ultimately be performed by a Environet’s Health and Safety Officer, as part of the site-specific Health and Safety Plan (HSP). 

## 2.3 Regulatory Considerations

The primary regulation dealing with drum hand ling in hazardous waste operations is section (J) of 29 CFR 1910.120. These OSHA regulations are unique to hazardous waste operations and do not cover all contingencies.c:\cliff\sop8.doc 3-1 SOP No. 8 

# Section 3 Drum Handling Procedures
3.1 Movement of Drums

The movement of full 55-gallon drums sole ly by hand is not recommended. Full drums should be moved with a dolly, hoist, sling, drum carrier, front end-loader, or other specialized device. A hydraulic drum grappler works well in certain applications. When drums are being moved, suspended, or overpack ed, personnel should stand well clear of the drum. 

## 3.2 Inspection of Drums

Prior to any handling, drums with unknown conten ts should be visually inspected for any words, symbols or labels on the drum surface wh ich would indicate the nature of its contents. A careful inspection should also be made for signs of leakage, rusting, corrosion, or bulging. If the drum is of unusual construction or materi al, such as nickel or stainless steel, it may contain a particularly hazardous or sensitive ma terial. The type of drumhead and type of bungs (if any) should be inspected. If the whole drum lid is removable, it may be designed to contain solid materials. If it has a bung (or bungs ) it may be designed to contain a liquid. If the drum has a polyethylene or PVC liner, it ma y have been designed to contain a corrosive material. The top of the drum and the ar ea around the bungs should be inspected for any signs of crystal formation, staining or unusual materials on the surface. An experienced drum handler may, on occasion, lightly tap the exterior of the drum or rock it very lightly to attempt to determine the level or amount of mate rial in the drum. The drum may need to be photographed and numbered during the inspection process. 

## 3.3 Spill Control During Drum Handling

Spills or leaks may occur during drum moveme nt and handling. Absorbent materials (clay, oil-dry, etc.) should be readily available in sufficient quantity to absorb spilled or leaked material. Where large spills could occur, a containment berm should be constructed around the area. A special pad for drum handling (concrete, HDPE, etc.) with containment berms may be required for certain types of work. Spill control should be performed by appropriately trained personnel wearing adequate PPE. A Spill Plan should be part of the HSP.c:\cliff\sop8.doc 3-2 SOP No. 8 

## 3.4 Opening Drums

A non-sparking bung wrench should be used for removing bungs to gain access to the drum interior. An appropriately rated fire extinguish er should be on hand ready for use to control incipient fires. OSHA specifies that a "suita ble shield" be placed between the employee and the drum being opened to protect the employ ee in case of accidental explosion. If there appears to be real danger of accidental expl osion, the drum should be opened remotely. One of the best ways to do this is to use a bron ze spike mounted on the end of a backhoe arm. The backhoe operator looks out through a clear explosion shield. The spike is used to punch a hole through the surface of the drum. A variet y of pneumatic and hydraulic remote drumoperating devices may be available. The efficien cy of their use must be evaluated on a caseby-case basis. 

## 3.5 Drum Overpacking

Leaking fifty-five gallon drums are usually overpacked into an 85-gallon overpack drum. There are a variety of ways to perform this sa fely. It can be done by vertical suspension and insertion or it may be done by sliding the two drums together horizontally (laying down). If the drum to be overpacked is suspended, it must be firmly held by a scissor clamp or other positive gripping device.

Do not contact the drum with hands while it is suspended. Use a board or other device to steady or position the drum which is being overpack ed. If a forklift is us ed, the operator must have specialized training prior to performi ng drum overpacking. Horizontal overpacking may be a safer technique in some cases. However, great care must be exercised to avoid back injury when pushing the overpacked drum into an upright position.Page 1 of 6

# Section 1 Purpose

The purpose of this Standard Operating Proce dure is to provide guidance in preparing for contingency or emergency situations during fi eld activities. Accidents can and do happen. However, with adequate planning and prepare dness resulting consequence can be minimized or prevented.

Emergency preparedness starts with advanced planning. It requires anticipation of potential problems or hazards. Proper emergency preparedness involves use of the project health and safety plan that may address emergency situations. It involves training, site orientation of personnel, medical information of personnel, and availability of emergency equipment and services.


# Section 2 Types of Emergencies

There are three major categories of emergencies that can occur during hazardous waste site investigations. They are medical emergencies, accidents, and safety equipment problems.



## 2.1 Medical Emergencies

Medical emergencies can be described as situations that present a significant threat to the health of personnel involved in site investigations. These can result from chemical exposures, heat stress, cold stress, and poisonous insect or snake bites. Medical emergencies must be dealt with immediately and proper care should be administered. This may be in the form of first aid and emergency hospitalization.



## 2.2 Accidents

Accidents can result from physical hazards on a s ite. These hazards can include tripping, catching, cutting, and may be associated with debris on a site or heavy equipment used in the investigation. Accidents may include:

• Broken bones;

• Burns;

• Sprains;Page 4 of 6 • Puncture wounds;

• Electrical shock; and

• Cuts by contaminated materials.

Appropriate medical attention must be provided to individuals involved in site investigations who have suffered an accident.



## 2.3 Safety Equipment Problems

A source of emergency may develop due to malfunc tion or other problem associated with safety equipment being utilized by investigative personnel. These types of problems may or may not result in emergency situations. However, safety equipm ent problems must be corrected before proceeding with field investigative activities. Safety problems may include:

• Leaks or tears in protective clothing;

• Failure of respiratory protective devi ces (SCBA, air-purifying respirators); and

• Encountering contaminants for which pres cribed protective equipment may not be suitable.


# Section 3 Advance Planning

Advance planning should be practiced and include a ssessments of potential hazards or problems that may be encountered. Emergency preparedness should be addressed in the site safety plan. It should consider:

• Hazard evaluation;

• Emergency precautions;

• Hospital/poison control centers (telephone numbers);

• Emergency transportation systems (fire, police, ambulance);

o Emergency routes (maps, dry runs); and

o Escape routes:

 On-site escape (rapid evacuation to safe area)

 Off-site escape (best means of evacuation from site).Page 5 of 6 

# Section 4 Training

Investigative teams should include personnel with training in first aid and CPR. Personnel should become familiar with site area, available equipment, and emergency services available.


# Section 5 Medical Surveillance Information

Personnel should be aware of any sp ecial medical problems of individual team members. This may include allergies, insect stings, poison plants, penicillin, etc.


# Section 6 Emergency Equipment

Provisions should be made to have appropriate emergency equipment available and in proper working condition. This equipment may include:

• First aid kits;

• Eye wash kits - fill and pressurize;

• Fire extinguisher;

• Emergency oxygen;

• Splints;

• Stretcher;

• Blankets; and

• Life vests.

Equipment should be checked before commencing site investigation activities, and defective equipment repaired or replaced before performing site investigation. Provisions should be made for redundant or back-up safety equipment.


# Section 7 Safety Practices

The following safety practices should be utilized to prevent or deal with emergency situations:

1. A continuous line-of-sight should be main tained between work party downrange and personnel at the command post. Personne l stationed beyond the command post, inPage 6 of 6 order to maintain the line-of-sight with the work party, must be outfitted with appropriate protective equipment. 2. Person should be dressed to same degree as the work party in order to provide an extra man for any needed rescue effort. 3. Communications should be maintained and work party must have system for rapid and clear distress call back to command post. 4. Check to insure that all preplanning information is correct. 5. Maintain thorough knowledge of expected weather conditions. Avoid working in wet weather, electrical storms, extrem ely hot conditions, or extremely cold conditions. 6. Thoroughly understand tasks to be performed. 7. Thoroughly brief all team members on all aspects of the tasks.


# Section 8 Documentation

Records should be maintained with regard to em ergency situations. Incident/Accident Reports should be filed in the event of an incident or accident (see OP SOP-103).

The display shows, “Apply Gas Now!” Turn on the valve of the span gas supply. 15. The display shows, “Wait... 30”, with a count -down timer showing the number of remaining seconds while the monitor performs the calibration. 16. When the countdown timer reaches zero, the di splay shows the calibrated value. The reading should be very close to the span gas value. 17. After a span calibration is completed, the disp lay will show the message, “Update Data Span Cal Done! Turn Off Gas”. 18. Turn off the flow of gas. Disconnect the calibration adapter from the MiniRAE 2000. 19. Press any key and it returns back to “Span Gas Cal?” 20. Press and hold the MODE key for five seconds to turn off the instrument. 

## 2.3 GEM 2000 Gas Meter

WARNING : The GEM 2000 is not certified as intrinsically safe. The following procedure MUST NOT be done in a confined space or where there is any chance of sparking or ignition. No smoking, exposed lighting, or other sources of ignition should be in the area. On the GEM 2000, ensure that the exhaust gas is safe, not blocked and properly vent ed away from you. Ensure that no leaks are present. Unless all above conditions are maintain ed, an explosion could occur resulting in serious injury or death.
Primary Calibration
Primary calibration of the GEM 2000 is accomplishe d at the factory using a gas mixture of 50 percent (%) methane (CH 4 ), 35% carbon dioxide (CO 2 ) for CH 4 and CO 2 calibration and gas mixture of 2% oxygen (O 2 ), balance nitrogen (N 2 ) for O 2 calibration.

## 2.4 LANDTEC GA-90 Landfill Gas Analyzer

WARNING: The LANDTEC GA-90 is not certified as intrinsically safe. The following procedures MUST NOT be done in a confined space such as vaults, excavations, indoors, or where there is any chance of sparking or ignition. Ensure that ex haust gas is safe, not blocked and properly vented away from you. Ensure no leaks are present. Unless all above conditions are maintained, an explosion could result causing serious injury or death.
Primary Calibration
The GA-90 is a portable scientific field instrument that does require factory calibration using various gas mixtures in an environmental chamber at recommended six month intervals under normal landfill usage. Factory calibration has been designed to give the best possible results over a wide range of conditions; however, the instrument’s accuracy can be improved in specific operating ranges by performing “field calibration.” At any time, the GA-90 can be reset by returning to the “factory settings.” This clears the GA-90 of any user calibration setting and restores the GA-90 to its original factory calibration.2-8 Field Calibration
Field calibration should be performed prior to taking a series of gas or pressure readings. It is important to field calibrate the GA-90 on-site af ter the instrument has stabilized at working temperature. Field calibration is menu-guided and can be completed in about 10 minutes.
To perform field calibration, the following items are required:

1. gas mixture of 50% CH 4 and 35% CO 2 ;

2. gas mixture of 2% O 2 and 98% N 2 ;

3. pressure regulators for the above cylinders cap able of regulating in the range of 0 to 5 pound-force per square inch gauge (psig) fitted with connectors suitable for 1⁄4 inch Tygon tubing;

4. regulator/flow meter capable of measuring in the range of 100 to 600 cubic centimeter (cc) per minute maximum with fitting suitable for 1⁄4 inch Tygon tubing or LANDTEC regulator which is set to deliver the required flow; and

5. interconnecting lengths of 1⁄4 inch Tygon tubing.

# Section 4 Maintenance Procedures

4.1 Horiba Multiparameter Probe

Sensor Probe
After use, wash with distilled water and wipe off all contamination. Pour about 20 ml of distilled water into the probe cap, install it on the sensor probe, and store in the carrying case.
In order to use the instrument regularly for a l ong time, store it after wiping off all contamination from the cable, sensor probe, and sensors.

TEMP/COND/TURB Unit

1. To remove contamination, remove the lid from the cell.

2. Clean the unit in distilled water. If the unit is severely contaminated, use an absorbent cotton to remove contamination.

3. Attach the lid to the cell block before storage.
pH/ORP Sensor
To remove contamination, use a piece of gau ze dampened with detergent and wipe off the contamination.
For long-term storage, remove the sensor from the sensor probe and check that the internal solution replenishment port is closed. Then, attach a seal to the liquid junction and attach the rubber caps before storage.
For monthly maintenance, replace the internal solution as described below:

1. remove the sensor from the sensor probe using a sensor spanner;

2. open the internal solution replenishment rubbe r stopper and remove the internal solution with a syringe;

3. inject new internal solution to the level near the rubber stopper. Be careful to avoid air bubbles from coming in the solution; and

4. attach the sensor to the sensor probe.

DO Sensor
To remove contamination, wipe off contamination with gauze to avoid damage to the diaphragm.4-2 For long-term storage, remove the DO sensor from th e sensor probe using a sensor spanner. Set the supplied short socket and store the sensor in a cool (0 to 10 oC), dark place.
To replace the diaphragm:

1. Cut a diaphragm sheet to about 3 x 3 centimeters (c m) in size. Do not get any fingerprints or dust on the center part of the square.

2. Detach the DO sensor from the sensor probe.

3. Detach the protection tube that holds the diaphragm in place.

4. Detach the diaphragm retaining ring and diaphr agm. Replace the diaphragm retaining ring and diaphragm if damaged or no longer functional.

5. Set the sensor in the replacement stand and fill th e internal solution with the attached syringe until the sensor tip is soaked with the solution.

6. Fit the diaphragm retaining ring into the diaphr agm retaining plate. Then, lay the diaphragm over the sensor and carefully cover with the ring and plate so that the diaphragm does not wrinkle. Finally, remove the retaining plate.

7. Cut the draped edge of the diaphragm to the shape of the sensor.

8. Check that there are no bubbles inside the sensor and tighten the protection tube securely.

9. Check that the diaphragm is tightly attached and that it is not wrinkled.



## 4.2 MiniRAE 2000 Portable VOC Monitor

Battery Charging and Replacement
Recharge the MiniRAE 2000 before and after fieldw ork. A fully charged battery runs a MiniRAE 2000 monitor for 10 hours continuously. The char ging time is less than 10 hours for a fully discharged battery. The battery may be replaced in the field (in an area known to be non-hazardous) if required.
Replacing Battery Pack

1. Turn off the power of the MiniRAE 2000.

2. Unscrew the two battery compartment screws located on the bottom of the monitor and remove the cover.

3. Remove the battery pack from the compartment.4-3 4. Replace with a fully charged spare battery pack inside the battery compartment. Make sure the battery pack is oriented properly inside the compartment.

5. Close the battery cover and tighten the two screws.
Replacing Alkaline Battery Adapter

1. Insert four fresh “AA” size alkaline batteries into the alkaline battery holder. Make sure that the polarity of the batteries is correct.

2. Follow the same procedure as described above to replace the battery holder.
Note: The internal charging circuit is designed to prevent charging to alkaline batteries.
PID Sensor and Lamp Cleaning/Replacement
Note: Normally the cleaning procedure is not need ed. Clean the PID sensor module, the lamp, and the lamp housing only when one of the following happened:

1. the reading is inaccurate even after calibration;

2. the reading is very sensitive to air moisture; or

3. a chemical liquid has entered into the unit and damaged the unit.
Use of the water trap filter will help prevent contamination.
To access the sensor components and lamp, gently unscrew the lamp-housing cap. Remove the sensor adapter with the gas inlet probe and the me tal filter together. Then, hold the PID sensor and pull straight out to avoid bending the electrical pins on the sensor. A slight gentle rocking motion helps to release the sensor.

To Clean the PID Sensor:

1. Place the entire PID sensor module into analytical grade methanol.

2. Dry the sensor thoroughly. Never touch the electrodes of the sensor by hand.

3. Use a methanol-soaked cotton swab to wipe off the lamp housing where it contacts the sensor when the sensor is installed.

4. Turn over the sensor so that the pins point out and up and the sensor cavity is visible. Examine the sensor electrodes for any corrosion, damage, or bending out of alignment. The metal sensor electrode “fingers” should be flat and straight. If necessary, carefully bend the sensor fingers to ensure that they do not touc h the Teflon portions and that they are parallel to each other. Make sure that the nuts on the sensor pins are snug but not over tight. If the sensor is corroded or otherwise damaged, it should be replaced.4-4 

## 4.3 GEM 2000 Gas Meter

Battery/Charging
The battery used in the GEM 2000 is a Nickel Meta l Hydride manufactured as an encapsulated pack from six individual cells. This type of battery is not susceptible to “memory effects” although it is not recommended that the unit be given short-term charges. When the flashing light emitting diode (LED) indicates “Charging Complete”, disconnect the charger.
The battery charger indicates when the unit is chargi ng, charged, or if there is a fault. A full charge should take approximately two hours.
Taking Probe Readings
Prior to going to the test site, ensure:

• the water trap has a clean and dry filter;

• the inlet-port particulate filter is clean and dry;

• a supply of spare filters is available;

• the battery has a good charge;

• the CH 4 , CO 2 , and O 2 readings have been auto-zeroed, without gas concentration present; and

• check the span calibration with a known concentration calibration gas.

Travel to the site with the instru ment in the vehicle’s interior – not in the trunk or truck bed, where it may be subjected to extremes of temperature and possible shock damage. This may cause erroneous readings.
When moving around the site, protect the instrument from strong direct sunlight, heavy rain, or wind-chill. Strong direct sunlight can raise the temperature of the instrument beyond its operating range. If this occurs, the liquid crystal display (LCD) will appear almost black and the contrast setting cannot alter the contrast. 

## 4.4 LANDTEC GA-90 Landfill Gas Analyzer

Battery/Charging
The internal battery pack of the GA-90 is designed to be recharged many times but as with all nickel-cadmium cells, certain rules should be observed or the batteries will not provide their full power or charge cycles.4-5 1. Discharge the batteries by setting logging function for a five minute interval and pump running to 90 seconds. The unit will run until batteries are discharged.

2. Charge batteries for at least 14 hours. LANDTEC chargers will not over charge batteries.

3. Never try to operate the GA-90 while batteries are charging.

4. When charging the battery overnight, lay the GA-90 flat or stand upright.

5. If the unit is to be stored for a long period, charge the internal batteries prior to storage. Recharge the unit every two months during storage and store flat or the O 2 sensor may ultimately dry out. This condition can be corrected with normal use.
Battery Shut-Off
A circuit within the GA-90 continuously monitors the battery voltage. If the battery voltage falls below a predetermined level, the unit will automatically shut itself off in order to prevent memory loss. If the unit shuts itself off, the unit requires a full charge of 14 hours to restore the battery to its maximum level.
Battery Low Symbol
When the battery voltage drops below 60% capacity, a Battery Symbol will appear on the top right corner of the display screen. Approximately tw o hours of full pump power remain when the symbol is displayed.
Automatic Power-Off
The GA-90 has an automatic power-off time to conserve battery power. If no key is pressed for 15 minutes, the unit will automatically switch itsel f off (no stored readings will be lost).
Emergency Battery Power
In emergencies, the GA-90 may be operated with six “C” sized alkaline batteries. To use alkaline cells, remove the nickel-cadmium battery pack by using a Phillips screw driver on the back battery compartment and insert the “C” cells. DO NOT use the battery charger in conjunction with standard alkaline batteries. They can explode if re-charged.
Cleaning
The polycarbonate membrane panel may be wiped clean with soapy water and a damp cloth if required.
Dust Caps
Always keep the protective dust caps in place when ports and connectors are not in use.4-6 Filters
The unit is equipped with two filters. One filter is in-line in the sample hose and can be easily accessed by unscrewing the filter holder. The second filter is located just inside the sample port inlet. This filter can be accessed by unscrewing (counter-clockwise) the port using a screwdriver or small coin. Inspection/replacement instructions are as follows:

1. Both filters are sealed with o-rings. Periodically inspect the o-rings to check their condition. Replace the o-rings when they become nicked, cut, swelled, or otherwise damaged. DO NOT OVERTIGHTEN O-RINGS.

2. Replace the filter when the sample pump has difficulty drawing a sample of gas into the unit or a “Flow Fail” message appears on the screen and a continuous audible warning is heard.
Storage and Travel

1. Store the GA-90 in its protective hard case when taking it from site to site.

2. When in use, keep the GA-90 in its protective soft case.

3. The unit should not be left out in direct sunlight for long periods of time as this will raise the temperature inside the case which could cause damage to components. The GA-90 may not operate or may operate erratically if it gets too hot. Let it cool before trying to use.5-1 

# Section 5 Documentation

The Field Team Leader and Site Health and Safe ty Officer will review calibration and maintenance records on a regular basis to ensure that required maintenance is being performed. These activities will be recorded in the field logbook to documen t that established calibration and maintenance procedures have been followed. Entries made on the equipment calibration log regarding the status of any field equipment will contain, but are not necessarily limited to, the following information:

• date and time of calibration;

• name of person conducting the calibration;

• type of equipment being serviced, and identification number (such as serial number);

• reference standard used for calibration (such as pH buffer solutions);

• calibration and/or maintenance procedure used; and

• other pertinent information.
Field instruments will be checked and calibrated pr ior to their use on site, and batteries will be charged and checked daily where applicable. E quipment that fails calibration and/or becomes otherwise inoperable during the field investigation will be removed from service and segregated to prevent inadvertent use. Such equipment will be properly tagged to indicat e that it should not be used until the nature of the problem can be dete rmined. Equipment requiring repair or recalibration must be approved for use by the Site Manager or Site Health and Safety Officer prior to placement back into service. Equipment that cannot be repaired or recalibrated will be replaced.
All field instruments will be properly protected ag ainst inclement weather conditions during the field investigation. Each instrument is specially designed to maintain its operating integrity during variable temperature ranges that are representa tive of ranges that will be encountered during expected working conditions. At the end of each wo rking day, all field equipment will be taken out of the field and placed in a dry room for overnight storage.5-2 This page is intentionally left blank.Table 5-1: Field Equipment Calibration and MaintenanceEquipment Calibration Procedure Calibration Frequency Maintenance ProcedureHoriba U22MultiparameterProbeTwo-point calibrate instrument.Auto calibrate instrument.Every six months.Before each day's use.Wash probe after every measurement.Replace ORP/pH sensor internal fluid monthly.Replace DO diaphragm as needed.Check battery charge and replace if necessary.MiniRAE 2000Factory calibrate instrument.Calibrate using 100 ppm isobutylene.Annually.Before each day's use.Charge battery daily.GEM 2000Factory calibrate instrument.Calibrate instrument using standard gas mixtures.Annually.Before each day's use.Charge battery daily.LANDTECGA-90Factory calibrate instrument.Calibrate instrument using calibration gases.Every six months.Before each day’s use.Charge battery daily.Replace filters and o-rings as necessary.

# Section 1 Purpose

The purpose of this Operating Procedure (OP) is to establish Environet, Inc. (EI) procedures and responsibilities for the administration of a hear ing conservation program. A proper hearing conservation program will reduce the risk of oc cupationally induced hearing loss and provide education and guidance for the prevention of "lifestyle" induced hearing loss.


# Section 2 Hazard Information

Excessive noise exposure can cause both tem porary and permanent effects on hearing. The temporary effects of excessive noise incl ude ringing in the ears, interference with communication, and hearing threshold changes. The effect of long-term excessive noise includes varying degrees of noise induced hearing loss.

The damaging effects of noise are dependent on the noise intensity (decibels), the time of exposure, the noise frequency (Hertz), and i ndividual susceptibility. The Occupational Safety and Health Administration (OSHA) Permissi ble Exposure Limits (PELs) and American Conference of Governmental Indus trial Hygienists (ACGIH) Threshold Limit Values (TLVs) set exposure limits based on exposure per day (in hours) and sound intensity (in decibels A scale or dBA). Exposures above these limits require use of hearing protection (plugs or muffs) to reduce the sound level or the use of noise engineering controls to reduce the sound level.

It is known that noise intensity above 85 dBA for prolonged periods will induce hearing loss. Eighty-five dBA represents a noise level where normal conversation is difficult and individuals will be shouting or talking into the ear of the person to be understood. 

# Section 3 Requirements

OSHA regulations issued in late 1981 require a hearing conservation program for workers exposed to 85 dBA as an 8-hour time-weighted average.

The OSHA regulation addresses several requireme nts for a good hearing conservation program. These requirements are as follows:Page 4 of 6  Noise exposure monitoring

 Audiometric testing

 Hearing protectors

 Training programs

 Access to information

 Recordkeeping and posting


# Section 4 Responsibilities

Each employee has the responsibility to comply with all aspects of this Operating Procedure. Managers with input from the Health and Safety Officer (HSO)'s and Site Safety Officer (SSO)'s are responsible for enforcing the provisions of th is Operating Procedure as it applies to field work. Scheduling of audiograms (accomplished through Medical Surveillance) and training are the responsibility of the HSO and Corporate Health and Safety Officer (CHSO).


# Section 5 Noise Exposure Monitoring

The SSO with assistance from the HSO and/or CHSO will determine when noise monitoring is required for jobs where EI employees are potentia lly exposed to excessive noise. The SSO/HSO will perform noise monitoring as necessary a nd make recommendations to assure compliance with Section 212.3 of this Operating Procedure. Engineering controls, ear protection, and posting may be required to comply with Section 212.3. In jobs where EI is working in a client's noisy area, EI personnel will comply with the clie nt's existing hearing conservation program. If a client has a noisy area and has no hearing conser vation program, EI will establish a plan for its employees and subcontractors to be in compliance with Section 212.3.


# Section 6 Training

All workers required to wear hear ing protectors will be trained in their proper use. In addition, all workers who may be exposed to greater th an 85 dBA will be provided refresher training.Page 5 of 6 This training will include at least the following: (1) Effects of noise on hearing; (2) the purpose, selection, fitting, use and care of hearing protector s; and (3) the purpose of audiometric testing and an explanation of the test procedure.


# Section 7 Hearing Protectors

When hearing protectors are required the empl oyee must have received training on the proper use. Proper noise reduction ratings will be a pplied by the HSO/CHSO to the noise in the environment.

Hearing protectors act as barriers to reduce sound entering the ear. Noise Reduction Ratings (NRR) for each product reflects the effectiveness of the protector chosen. Generally, muffs offer a greater NRR (25-30 dBA) than plugs (15-25 dB A). Comfort is an important factor when wearing ear protection over many hours; it is reco mmended to try different types of plugs or muffs to determine the best combination of comfort and fit.


# Section 8 Audiometric Testing

Audiograms are administered upon employment and annually/biennially thereafter. The audiograms are conducted by the medical clinics a pproved for EI physicals and must meet all the applicable requirements (including Appendices C, D, and E of the OSHA Std. Title 29 Code of Federal Regulations (CFR) 1910.95). The local medical clinic in consultation with Greaney Medical will comply with applicable provisi ons of Title 29 CFR 1910.95(g) with regard to recordkeeping.Page 6 of 6 

# Section 9 Access to Information, Recordkeeping

Each office shall have a copy of Title 29 CFR 1910.95 available for any employee requesting access to the standard. Employee training aids sh all also be available to any employee. All noise monitoring data shall be retained for at l east two years and Greaney Medical shall maintain the audiometric results for thirty years beyond the last date of employment.

# Section 4 Procedures

The following procedures for containerizi ng, preserving, handling, and shipping samples meet criteria as specified by United States Army Corps of Engineers (USACE) guidelines.



## 4.1 Sample Containers and Preservative

Only sample containers certified as clean by the manufacturer or laboratory and meeting contract requirements will be used for envir onmental sample collection. The containers and preservatives may be obtained from the contr acted analytical laboratory, their designated supplier, or a suitable supply company. Any pr eservative(s) required may be added to the container by the contracted analytical laborator y, field sampling team, and/or on-site chemist prior to, during or after sample collection (with the exception of volatiles).
Recommended sample containers, preservatives , and holding times for analytical methods, are shown in the Sampling and Analysis Plan (SAP).



## 4.2 Container Labeling, Decontamination, and Field Packaging

The sample bottles will be labeled by the field sampling team. Collection time and date will be completed in the field by the sampler. The la bels will be filled out at the time of collection and indicate:

• Activity name and/or number

• Unique sample number

• Sample time and date

• Chemical preservative used

• Sample type (grab, composite)

• Analyses required

• Filtered/unfiltered

• Comments or special precautions, as needed

• Sampler's initials
The sample label will be marked with a waterpr oof pen. Clear tape will be placed over labels before sampling to assure that the labels remain legible.
After sampling, the exterior of the sample cont ainers will be decontaminated according to the Decontamination SOP, and placed in cooler s dedicated for sample transportation. The collected samples will be immediately placed in a cooler packed with wet ice, or otherPage 7 of 11 appropriate means to bring the sample temperatur es to 4° ± 2°C. Samples will not be frozen. The temperature in the coolers will be mainta ined at approximately 4°C by adding sealed plastic bags containing blue ice (or an equivalent) to the coolers.



## 4.3 Chain of Custody

Official custody of samples will be maintained and documented from the time of collection until the time that valid analytical results ha ve been obtained or the laboratory has been released to dispose of the samples. The samp ling team will be responsible for initiating the original chain of custody (COC) and will sign and date the COC when relinquishing sample custody. The COC and sample labels will be check ed to verify that samples are accounted for and in good condition, and that no errors were made.
A sample is considered to be in a person's custody if any of the following conditions are met:

• The sample is in the person's physical possession.

• The sample is in the line of sight of the person after they have taken possession.

• The sample is secured by that person to prohibit any tampering.

• A sample is secured by the person in po ssession in an area which only authorized personnel can enter.



### 4.3.1 Tampering of Sample Containers If, at any time after samples have been secured, custody seals on the cooler are identified as having been tampered with, this procedure will be followed to ensure that sample integrity has not been compromised.

• Check cooler to verify the temperature is between 2°C to 6°C.

• Check with personnel having access to sa mple coolers to verify possible inadvertent tampering.

• Check every sample container for any si gns of tampering, such as loose lids, foreign objects in containers, broken or leaking containers, etc.

• Verify adequate and appropriate packaging.

• Document findings of the incident in the sample manager's logbook.

If it is determined that malicious tampering of samples has occurred and/or it is believed that sample integrity has been compromised, the s ubcontractor will immediately contact the site manager. If it can be determined that sample integrity has not been compromised based on the above criteria, document findings in a logbook.Page 8 of 11 

### 4.3.2 Chain of Custody Form A three-page carbonless COC form will be used. A COC is shown at the end of this SOP. The original and second (or yellow) copy will be included with the samples to be shipped enclosed in a plastic bag and taped inside the lid of the cooler. The third (or pink) copy will be sent to the Environet Data/Sample Manager, and the photocopy of the original will remain on file with the field personnel. The contr act laboratory will sign as having received the samples and return the yellow copy of the COC to Environet for verification by the Environet Data/Sample Manager. The yellow and pink c opies will then be matched and filed to complete the chain of custody procedure for the field sampling efforts. The white (original) will be placed in the appropriate data pack age by the laboratory. The COC will include the following information:

• Unique sample number and sample location

• Project number

• Date and time of sample collection

• Signature or initials of collector or field custodian

• Laboratory designation

• Sample matrix

• Condition of sample cooler on receipt at the laboratory (includes temperature inside the cooler)

• COC number

• Signature and date blocks for personnel relinquishing or receiving sample custody

• Space for additional comments

• Name and phone number of emergency contact person

• Analyses requested

• Preservatives added to the sample

• Any nonconformance with this SOP identified by the laboratory



## 4.4 Field Data Documentation

Field descriptions, measurements, and observati ons will be recorded on the appropriate field data forms or logbook in accordance with the SA P and appropriate SOPs. The original data forms will be collected and filed on-site by the de signated staff. Data will also be recorded in field logbooks. Field data will be filled out at the time a sample is taken and will include, but not be limited to, the following information:

• Sampling activity name and number

• Sampling point name and number

• Sample number

• Name(s) of collector(s) and others present

• Date and time of sample collection

• Sample container tag/label number (if appropriate)

• Preservative(s) usedPage 9 of 11 • Requested analyses

• Sample matrix

• Filtered/unfiltered

• Designation of QC samples (ONLY for MS and MSD)

• Collection methods

• COC numbers

• Field observations and measurements during sampling (comment section)

• Signature of responsible observer



## 4.5 Packaging and Shipping

Samples will be packaged properly to prevent breakage of containers, leakage of contents, and to ensure the samples arrive at the analy tical laboratory within the required temperature range of 2°C to 6°C. The following procedur es will be followed during the packaging and shipping process.

• Check container lids and tighten as necessary.

• Wrap individual sample containers, if glass, with bubble wrap.

• Place sample containers in re-sealable plastic bags as secondary containment.

• Place sufficient amounts of bubble wrap in the bottom and sides of the shipping cooler to prevent movement of contents.

• Add double bagged ice to the cooler in qua ntities adequate to maintain required temperature of 2°C to 6°C. Line the botto m, sides and top of cooler to ensure proper shipment temperature. (Using six pieces of blue ice per 48 qt. cooler is not uncommon)

• Line the inside of the area created by the ice placement with a plastic trash bag and place the wrapped samples inside in an upright position.

• Tie shut the trash bag holding the samples.

• Fill excess space in the cooler with packi ng material (i.e. bubble wrap) to prevent movement of sample containers.

• Review the previously completed COC pa perwork and sample packaging before proceeding.

• The white and yellow portions of the COC are then placed inside a plastic bag, and taped inside of the cooler lid.

• Close the cooler lid and seal with appropriate packaging tape in a manner to prevent inadvertent opening during shipment.

• Place two custody seals on the cooler in se parate areas that would indicate if tampering had occurred.

The following markings will be placed on the top of the cooler:

• This end upPage 10 of 11 • Fragile

• Next day priority service

• Shipment delivery address

• Sender's return address

• A completed shipping bill should be made fo r the carrier of choice and taped to the top of the cooler using the envelope provided by the shipper.

• The express carrier should be called to arrange pick-up of the cooler(s), or delivered to the nearest carrier's office.

• The pink copy of the shipping bill should be retained by the sample manager for attachment to the pink copy of the corresponding COC(s).

An express carrier will be used to aid in meeting sample holding time requirements. The Environet Site Manager or designee is responsible for verifying that samples collected by the field team have been properly packed in i ce chests and for verifying the accuracy and completeness of sample labels and COC forms.
The following is a summary of steps to be followed to verify that paperwork is complete:

• Prepare sample labels prior to sampling for sampling crew.

• Receive samples from decontamination/sampling crews.

• Check or complete the COC form(s).

• Pack samples in cooler and verify COC accuracy.

• Verify all labels and forms to meet shipping requirements.

• Photocopy the COC(s) and retain th e photocopy and pink copy for Environet files.

• Send original COC(s) (white and yello w copy) to the contract laboratory.

• Photocopy field notes if required and send with COC.

• Obtain pink copy of shipping bill and staple to pink portion of corresponding COC(s).
