AEI Consultants (AEI) has been operating a soil vapor extraction (SVE) system at the above subject site since March 12, 2008. The SVE system consists of a 200 standard cubic feet per minute (SCFM) blower capable of developing a vacuum of 10 inches of mercury ("Hg), a single horizontal SVE well that was installed with a horizontal directional drill, above ground conveyance piping, and two Siemens Model VSC400 granular activated carbon (GAC) vessels, connected in series. The SVE system has been operating in compliance with a San Joaquin Valley Air Pollution Control District (SJVAPCD) Permit to Construct and Operate, dated December 12, 2007. The purpose of the Remediation Progress Report is to demonstrate that AEI has removed contamination to the extent possible by the SVE system, and to propose soil confirmation testing. Site Location and Description The subject property is part of Stine White Towne Center, a 4.6-acre commercial shopping center located on the southeast corner of White Lane and Stine Road in a commercial area in the City of Bakersfield, California. Immediately surrounding properties consist of a commercial shopping center, a Mobil gasoline station, and residential dwellings to the north across White Lane; a commercial shopping center to the east and across Stine Road to the west; and various office buildings to the south.

Gerry's Custom Hair Cutting occupies Unit D adjacent to the east and Two Two Amen Beauty Supply occupies Unit F adjacent to the west of the site. The dry cleaning facility operates a DCM in the southern half of the unit along the western wall. A bathroom and a boiler room are located in the southeastern and southwestern corners of the subject property, respectively. Asphalt-paved parking lots are located to the north and to the south of the site. Please see Figure 2 for a Site Plan that shows the locations of previous soil borings, vapor probes, and the SVE remediation system. Initial Distribution and Mass of Contaminant The PCE release has been reasonably well characterized laterally and vertically. PCE concentrations generally decreased to just above the laboratory detection limit or to non-detectable levels with increasing vertical depth and lateral distance from the DCM. The maximum radius of the soil PCE plume appeared to be approximately 75 feet from the apparent on-site release point, though elevated PCE concentrations were only generally detected in shallow soil (less than 5 feet bgs) in the immediate vicinity of the DCM. Previous soil analytical data are shown in Tables 1 and 2 below. Table 1 summarizes data for four shallow borings to a depth of 5 feet below ground surface (bgs). The borings were advanced in July 2003, and PCE concentrations in soil samples collected at 1 foot, 3 feet, and 5 feet bgs ranged from a minimum of non-detect to a maximum of 800 pg/Kg. Table 1.

Most of the PCE was found within 75 feet of the DCM above a depth of 5 Remediation Progress Report Holiday Cleaners 4200 Stine Road, Unit E Bakersfield, California 93307 AEI Project Number 271444 September 4,2008 Page 4 feet bgs. A cylindrical model is used to calculate the mass of affected soil as follows: Volume = 3.1416 x 75 feet x 75 feet x 5 feet = 88,358 cubic feet = 3,273.cubic yards. Multiplying by 1.3 tons per cubic yard gives 4,254 tons, which is equal to 8,508,500 pounds = 3,867,500 kg. Multiplying by the average PCE concentration in soil of 148 pg/Kg yields a total PCE mass of 572,390,000 pg = 572.4 grams = 1.26 pounds. Influent Vapor Concentrations vs. Time AEI visited the site weekly beginning on March 12, 2008 to perform routine maintenance, and to collect influent and effluent vapor samples with respect to the GAC treatment system. Appendix A contains laboratory analytical reports for analyses according to EPA Method 826013. Appendix B contains a plot of the concentration of tetrachloroethene (PCE) in influent vapor vs. elapsed pumping time in days. Starting on March 12, 2008, over a period of 50 days of pumping, the PCE concentration in influent vapor decreased from 74.1 micrograms per liter (Ng/L) to non-detect. Influent concentrations have been non-detect since June 16, 2008. Mass Removal Calculation Appendix C contains a spreadsheet that was used to calculate the mass of PCE removed from the soil by SVE. Input to the spreadsheet were minutes pumped at a given average system vacuum in inches of mercury (in Hg), the average system inlet flow rate in actual cubic feet per minute (ACFM) measured with a Velocicalc® flow meter, and the concentration of PCE in the influent vapor converted to parts per million by volume (ppmv). Output from the spreadsheet were the flow rate in standard cubic feet per minute adjusted for system vacuum (SCFM), pumped volume of air in cubic feet, the pumped volume of air in liters, the volume of PCE in liters, the moles of PCE pumped, the grams of PCE pumped, and the mass of PCE recovered in pounds. As of June 30, 2008, the total PCE recovered was 1.025 pounds. Rebound Testing According to the Remedial Action Plan (RAP), the remediation system was to be operated continuously until PCE concentrations in influent vapor become non- detectable or asymptotic. Influent concentrations were non-detect from May 5 through June 2, 2008. Remediation Progress Report Holiday Cleaners 4200 Stine Road, Unit Bakersfield, California 93307 AEI Project Number 271444 September 4,2008 Page S AEI shut down the system for one week for rebound testing. On June 10, AEI sampled influent and effluent vapor, and the influent vapor sample contained 1.4 pg/L of PCE. Additional rebound tests have been conducted; however, no detectable concentrations of PCE have been found. Health and Safety Plan AEI has prepared a site specific Health and Safety Plan (Appendix D) that provides procedures for protecting workers who are advancing boreholes using hand auger and Geoprobe® methodologies. The plan specifies the types of personal protective equipment that are necessary to protect workers against harmful exposure to volatile organic compounds (VOCs). A working area will be established to delineate the zone where hard hats, goggles, and steel-toed shoes must be worn, and where unauthorized personnel will not be allowed. Prior to conduct of any field activities, AEI will conduct a "tail-gate" health and safety meeting to review the Plan with all field personnel. The review will cover emergency procedures and transportation routes to the nearest emergency facility at the nearest local hospital. Confirmation Testing According to the RAP, "Once data indicate that cleanup goals have been achieved, AEI will collect soil samples in areas with previously elevated contaminant concentrations, and analyze the samples for VOCs via EPA Method 8260B to confirm that SVE has lowered soil contaminant concentrations to below remediation goals. (A goal of 90% reduction in contaminant level is a recognized limit for SVE.) AEI will issue a closure report to the BFD with confirmation sampling analysis results and request case closure." AEI recommends three confirmation borings: two hand auger borings to 5 feet bgs near the 133 and 134 locations because of the elevated concentrations of PCE in soil that were previously detected, and one Geoprobe® boring to 25 feet bgs near the 65 location. Locations of the three confirmation test soil borings are shown in Figure 2. Soil samples will be collected at 2 feet and 5 feet bgs in the hand auger borings at at 2 feet, 5 feet, and in five feet intervals to terminal depth in the Geoprobe® boring. Each soil sample will be examined for lithological classification and field- screened with a photoionization detector (PID) and by visual and olfactory t Remediation Progress Report Holiday Cleaners 4200 Stine Road, Unit E Bakersfield, California 93307 AEI Project Number 271444 September 4,2008 Page 6 means. Boreholes will be backfilled with hydrated bentonite chips and capped with concrete or asphalt upon completion of sampling. A maximum of ten soil samples will be collected via EPA Method 5035 protocol using disposable plastic syringes and 40-milliliter (mL) volatile organics analysis (VOA) vials containing sodium bisulfate (NaHSO4) preservative. Following EPA Method 5035 sample collection, each sample tube will be sealed on both ends with Teflon tape and plastic caps. All soil samples will be labeled for identification and stored in an iced cooler. Samples will be transported under proper chain-of-custody protocol to Alpha Scientific Corporation (ASC), a state- certified laboratory [Environmental Laboratory Accreditation Program (ELAP) Number 2633] in the City of Cerritos, California, for analysis of volatile organic compounds (VOCs) via EPA Method 8260B. All fieldwork and report writing will be performed under the supervision of Dr. Edward I. Wallick, a State of California Registered Professional Geologist. Summary and Recommendations AEI has been operating a SVE system at the subject site in order to remove PCE from shallow soil. Based on soil characterization data input to a cylindrical model, the mass of PCE released to the shallow soil was calculated at approximately 1.26 pounds. The mass of PCE in soil Concentrations of PCE in vapor influent to the GAC treatment system decreased from a maximum of approximately 74 pg/L to non detect after approximately 50 days of pumping. The estimated mass of PCE that has been removed by SVE was calculated at 1.025 pound. Therefore, approximately 81 percent of the PCE was removed by SVE. The fact that PCE concentrations in influent vapor decreased to non-detect, and that PCE concentrations have not rebounded indicates that the SVE treatment has been completed. AEI recommends no further SVE operations with the current equipment configuration. AEI recommends three soil confirmation borings near previous soil borings B3, B4, and B5. Two of the borings will be advanced with hand auger to 5 feet bgs, and the remaining boring will be advanced with a Geoprobe® to 20 feet bgs. Altogether, ten soil samples will be collected and analyzed for VOCs according to EPA Method 8260B. AEI respectively seeks speedy approval of these recommendations.

Inhalation—Any warning symptoms such as headache,dizziness,nausea,shortness of breath,etc.necessitate that the victim leave the immediate site area rapidly. If the victim stops breathing,assisting personnel should don breathing protection while removing them from the area. Persons trained in CPR should immediately begin initiated,while medical attention should be obtained as soon as possible. In case of evacuation, all vehicles/equipment should be turned off and personnel should immediately leave the work area. Personnel should reconnoiter at the specified meeting area located upwind of the affected area,such as the building exterior, site field office,property boundary,or other predesignated location,where all personnel will be accounted for. IF AN EMERGENCY ARISES,THE DESIGNATED RECONNOITER LOCATION FOR THIS PROJECT IS THE EXTERIOR OF THE SUBJECT PROPERTY BUILDING AT THE HOLIDAY CLEANERS PARIQNG LOT ALONG STINE ROAD. This location is located up-wind of the subject property,but is subject to change if prevailing weather conditions alter typical wind direction. Personnel should not reenter the work area following evacuation until: 1.)the condition causing the emergency has been corrected. 2.)All hazards have been assessed. 3.)The HASP has been reviewed. 4.)Personnel have been oriented on any changes in the HASP. All emergencies should be promptly reported to the SSO. HOSPITAL MAP RbVgST �� w r 1 'r i j � „ ,3 1mi Gl"n acres Rosedale Nwy.� r a.

C A Site Health and Safety Briefing or"Tailgate Safety Meeting"must be completed at the initiation of on-site activities and at at the beginning of site activities each day thereafter until the completion of AEI on-site activities. (Note:The actual briefing may be conducted off site,in the office for example,if conditions preclude or render impractical its completion on site.) The corresponding Site Orientation Record should be completed at the initiation of on-site activities and once per week thereafter. G The AEI Incident Investigation Form and the Subcontractor's Statement of Understanding Regarding Health and Safety Responsibilities form are to be completed on an as needed basis. EQUIPMENT AND CONTROLS[CAL OSHA 8 CCR 5192(d)and(2)(5)1 Based on an evaluation of the hazards at the site,PPE will be required for all personnel and visitors entering the controlled portion of the site.Protective equipment for each level of protection is summarized below. Both Level C and D PPE should be available on-site at during all phases of the project,as conditions may change and require additional PPE. Work should be conducted in Level D as long as breathing zone vapor concentrations remain at background or below 25 ppm,no breathing protection will be required. If on-site personnel fmd that breathing zone concentrations remain above 25 ppm for more than 5 minutes,then the SSO or PM will make a determination if breathing protection is needed. At this time,all work in the affected area should be suspended until a decision is made. Implementation of Level C PPE will be required if work continues during elevated breathing zone concentrations. Donning and use of respirators shall be performed in accordance with manufacturer specifications. Replacement of respirator cartridges shall be performed in accordance with manufacturer specifications. All respirators and cartridges shall be stored in air tight bags while not in use. Personal Protective Equipment—Level D Personal Protective Equipment—Level C ® Hearing Protection(as needed near loud equipment) ❑ Respirator Type: Half-Mask APR ® Hardhat ❑ Resp-Cartridge Type: Volatile/HEPA(P100) ® Outer Gloves Type:Nitrile or Leather(as needed) ❑ Others: ❑ Inner Gloves Type: ® Steel-toed boots/shoes ❑ Coveralls Type: Tyvek ❑ Outer Boots Type: ® Eye Protection with side shields ❑ Others: Monitoring Equipment r Other Equipment&Gear 2 ® PID Type: MiniRae 2000 Lamp Energy: 10.6 eV ® 10#ABC Fire Extinguisher when gasoline power equipment ❑ FID Type: present ® Cal gas and equipment type: Isobutylene 100 ppm ® Caution Tape ® Traffic Cones or Delineators El LEUOZ Meter Others: ® Warning Signs or Placards ❑ 4 Gas Meter ® Decon Buckets,Brushes,Detergent,Towels and Plastic Bags ® First Aid Kit ❑ Others: Notes: 1. All direct reading instruments should calibrated on site once/day using a cal-gas reference standard and in accordance with the manufacturer's instructions. 2 A 10-foot exclusion zone is required where ever available to control access to heavy equipment and/or hazardous exposure situations. Only authorized persons will be allowed to enter work zone. AEI Site-Specific Health,Safety and Accident Prevention Plan Page 4 September 4,2008 AIR MONITORING INSTRUMENTS AND ACTION LEVELS[CAL OSHA 8 CCR 5192(h)] Anticipated Chemical Hazards: volatile organic compounds[e.g.,chlorinated solvents] RID—Brea in Zone Readings: BTEX' Non BTEX 0 to 5 ppm 0 to 5 ppm Remain in Level D. Continuously monitor ambient breathing zone if organic vapor concentration exceeds 5 ppm for 5 minutes or a single reading of 25 ppm. If this occurs,proceed to Level C protection. 5 to 200 ppm 5 to 200 ppm Withdraw from work area,and proceed to Level C protection for re-entry,or discontinue operation. >200 ppm: >200 ppm: Secure operations,withdraw from work area,and discontinue work at that location until contaminants can be evaluated,and detailed HASP implemented. 'Action levels may be modified once benzene concentrations are documented for each task. BTEX=benzene,toluene,ethylbenzene,and xylenes Combustible Gas Indicator CGULEL Meter if required - ource:r • <100/.LEL: Continue to monitor with caution.Eliminate all ignition sources. • 10%to 20%LEL: Stop operations until appropriate vapor control measures(i e.foam,sand,polyethylene,film,portable blower etc.)and resample before resuming activity. Atmospheric vapor concentrations will be monitored via a photoionization detector(PID)or equivalent to determine appropriate action levels. The PID will be calibrated daily by AEI personnel prior to use. Calibration will be performed in accordance with the manufacturer specifications and recorded in a log book kept with the instrument. Ambient breathing space measurements should be collected every 15 minutes during excavation activities. Measurements will also be collected from the interior workspace as well as the soil stockpile and down-gradient areas. DECONTAMINATION PROCEDURES[CAL OSHA 8 CCR 5192(k)] All downhole soil and groundwater sampling equipment(e.g., sampling tubes, split spoons,hand augers,Hydropunch,etc), hand tools,purge pumps,water level indicators,etc.will be decontaminated before,between,and after use with Alconox or an equivalent phosphate-free detergent solution to reduce the risk of cross-contamination. Decontamination of all sampling equipment will consist of submerging the equipment in a detergent solution bath and scrubbing it with dedicated brushes. The equipment will then be placed in a rinse bath and agitated. A second rinse bath should occur if needed. All construction equipment such as excavators and should be thoroughly steam cleaned and rinsed. EMPLOYEE TRAINING[CAL OSHA 8 CCR 5192(e)] All personnel working on-site,must have had at a minimum the required 24-or 40-hour OSHA training for HAZWOPER with the annual 8-hour refresher,which includes the use of respirators and PPE. Annual individualized respirator fit testing is required of all applicable AEI employees working at the site. During daily the Site Health and Safety Briefing or "Tailgate Safety Meeting", at a minimum the following should be discussed: 1.) Scope of work, including personnel project responsibilities. 2.) A description of the levels of personal protection at the site and the steps taken to select each level. 3.) Emergency procedures. 4.) Nature of the known or anticipated hazards, including the location of the Material Safety Data Sheets (MSDS) for the chemicals at the site. 5.) Review safe work practices and identify any prohibited or forbidden practices. 6.)Permissible smoking location. Attendance at the Site Health and Safety Briefing or"Tailgate Safety Meeting"will be mandatory and all personnel coming on-site following the initial daily meeting will be subject to their own Site Health and Safety Briefing prior to entering the site. All personnel will be required to sign the Health and Safety Briefing/Site Orientation Record to signify understanding and adherence to AEPs HASP. AEI Site-Specific Health,Safety and Accident Prevention Plan Page 5 September 4,2008 HAZARD ASSESSMENT (® =Applies,or required item(s)available. ❑ =Not Applicable) HAZARD ASSESSMENT: PHYSICAL HAZARDS AND RELATED CONCERNS(CAL OSHA S CCR 5192) ❑ Confined Space Entry(CSE). Confined space entry means the potentially hazardous entry into any space which,by design,has limited openings for entry and exit,unfavorable natural ventilation which could contain or produce dangerous air contaminants,and which is not intended for continuous employee occupancy. Confined spaces include but are not limited to storage tanks, compartments of ships, process vessels,pits, silos,vats,degreasers,reaction vessels,boilers,ventilation and exhaust ducts,sewers,tunnels,underground utility vaults,and pipelines. Other environments which must be treated as confined spaces include test pits,and basements,garages,warehouses and other indoor areas where mechanical(i.e.,diesel,propane,gasoline or similarly powered)equipment must be operated for drilling or test pitting purposes. Confined space entry should be allowed only when absolutely necessary,and then only when all requirements of AEI's Confined Space Entry Control Program, and/or CSE Program Supplement for Indoor Drilling(and Similar Operations) and/or Trench and Excavation Safety and Health Guide(and CSE Program Supplement),contained in the Health and Safety Program Manual, have been satisfied. ® Construction Hazards, Drill Rigs, Backhoes, etc. The use of drill rigs, backhoes and other heavy equipment represent potentially serious construction hazards. Whenever such equipment is used,personnel in the vicinity should be limited to those who must be there to complete their assigned duties. All personnel must avoid standing within the turning radius of the equipment or below any suspended load. Job sites must be kept as clean,orderly and sanitary as possible. When water is used,care must be taken to avoid creating muddy or slippery conditions. Never turn your back to operating machinery. Never wear loose clothing jewelry,hair or other personal items around rotating equipment or other equipment that could may catch or ensnare loose clothing,jewelry,hair or other personal items. Always stand far enough away from operating machinery to prevent accident contact which may result from mechanical or human error. Additionally,the following basic personal protective measures must be observed: Hardhats must be worn to protect against bumps or falling objects. Safety glasses must be wom when necessary to protect against chemicals or other hazards. Steel-toed safety shoes or boots are also required. The shoes must be chemically resistant or protected with appropriately selected boots/coverings where necessary. Unless otherwise specified,normal workclothes must be worn. Gloves are also required whenever necessary to protect against hazardous contact,cuts,abrasions or other possible skin hazards. ❑ Drums and Buried Drums. As a precautionary measure,personnel must assume that labeled and unlabeled drums encountered during field activities contain hazardous materials until their contents can be confirmed and characterized. Personnel should recognize that drums are frequently mislabeled,particularly drums that are reused. Only trained and authorized personnel should be allowed to perform drum handling. Prior to any handling, drums must be visually inspected to gain as much information as possible about their contents. Trained field personnel must look for signs of deterioration such as corrosion,rust or leaks,and for signs that the drum is under pressure such as swelling or bulging. Drum-type and drumhead configuration may provide the observer with information about the type of material inside,(i.e.,a removable lid is designed to contain solids,while the presence of a bung indicates liquid storage). Although not usually anticipated,buried drums can be encountered when digging test pits. Therefore,the following provisions must be observed if drums are encountered. Machine excavation(i.e.,backhoe)should cease immediately anytime a drum is encountered. The appropriate management personnel should be notified immediately. All AEI personnel should be instructed to immediately leave the work area. ® Fire and Explosion. The possibility of flammable materials being encountered during field activities must be recognized and the appropriate steps necessary to minimize fire and explosion must be observed. This includes situations where excessive organic vapors or free product are encountered. When this occurs,monitoring with a combustible gas indicator(CGI),is required. Excessive organic vapors,for the purposes of initiating the use of a CGI,are defined as sustained readings(i.e.,continuous for at least five minutes)at or above 250 units or as an instantaneous reading at or above 1,000 units on the PID or FID,in close proximity(within 1 foot or less)of the borehole,test pit,sampling location or other area of potential exposure. In situations where hexane,methanol are needed for field activities,the following precautions must be observed: keep flammable and combustible materials away from heat,sparks and open flames;do not smoke around flammable or combustible materials;and keep all flammable and combustible liquids in approved and properly labeled safety containers. ❑ Landfill/Methane Hazards. Fire and explosion should be regarded as one of,if not the,most significant potential hazards associated with drilling operations and other intrusive work conducted at a landfill. Accordingly,all sources of ignition must be fully controlled. Failure to control ignition sources could result in fire,explosion and pose a serious threat to life and health. Control methods may include forced ventilation and/or filling the borehole with enough water to inhibit the release of methane and other gases which would otherwise escape through the top of the borehole. AEI Site-Specific Health,Safety and Accident Prevention Plan Page 6 September 4,2008 If forced(mechanical)ventilation is to be used,all such equipment must be approved for Class I,Division I hazardous atmospheres. The blower must be positioned to blow across the top of the borehole so that gases and vapors may be diluted as they exit the borehole.Do not attempt to suck out the gases or vapors. Blowers,all other mechanical equipment,and tools which could release sparks or static electricity must be bonded and grounded. Regardless of the gas/vapor control method used,the atmosphere surrounding the borehole must be frequently monitored using direct reading instruments approved for Class I,Division I hazardous atmospheres. Monitoring should be conducted within 1 to 2 feet of the top of the borehole. Do not insert sampling devices into the borehole. Never approach the auger or drill shaft while it is in operation. Regardless of actual instrument readings,if all sources of ignition can not be controlled,operations should be immediately shut down if readings equal or exceed 10%of LEL and the area evacuated until ignition sources have been eliminated. Ignition sources include,but are not limited to: smoking,static electricity,lighting,open flames,spontaneously ignitable substances,frictional heat or sparks,hot surfaces, radiant heat,electrical sparks,stray currents,cutting and welding,and ovens,furnaces and heating equipment. ® Heat and Cold Stress. Overexposure to temperature extremes can represent significant risks to personnel if simple precautions are not observed. Typical control measures designed to prevent heat stress include dressing properly,drinking plenty of the right fluids,and establishing an appropriate work/break regimen. Typical control measures designed to prevent cold stress also include dressing properly, and establishing an appropriate work/break regimen. ® Moving Vehicles,Traffic Safety. All vehicular traffic routes which could impact worker safety must be identified and communicated Whenever necessary,barriers or other methods must be established to prevent injury from moving vehicles. This is particularly important when field activities are conducted in parking lots,driveways,ramps or roadways ® Noise. Noise exposure can be affected by many factors including the number and types of noise sources(continuous vs.intermittent or impact),and the proximity to noise intensifying structures such walls or building which cause noise to bounce back or echo. The single most important factor effecting total noise exposure is distance from the source. The closer one is to the source the louder the noise. The operation of a drill rig,backhoe or other mechanical equipment can be sources of significant noise exposure. In order to reduce the exposure to this noise,personnel working in areas of excessive noise must use hearing protectors(ear plugs or ear muffs). Rule-of-Thumb: Wherever actual data from sound level meters or noise dosimeters is unavailable and it is necessary to raise one's voice above a normal conversational level to communicate with others within 3 to 5 feet away,hearingprotection should be worn. ® Overhead Utilities and Hazards. Overhead hazards can include low hanging structures which can cause injury due to bumping into them Other overhead hazards include falling objects,suspended loads,swinging loads and rotating equipment. Hardhats must be wom by personnel in areas were these types of physical hazards may be encountered. Barriers or other methods must also be used to exclude personnel from these areas were appropriate. Electrical wires are another significant overhead hazard. According to OSHA(29 CFR 1926.550),the minimum clearance which must be maintained from overhead electrical wires is 10 feet from an electrical source rated<50 kV. Sources rated>50 kV require a minimum clearance of 10 feet plus 0.4 inch per kV above 50 kV. ® Pedestrian Traffic. The uncontrolled presence of pedestrians on a drilling or excavation site can be hazardous to both pedestrians and site workers. The site should be surveyed to determine if,when and where pedestrian may gain access. This includes walkways,parking lots, gates and doorways. Barriers or caution tape should be used to exclude all pedestrian traffic. Exclusion of pedestrian traffic is intended to prevent injury to the pedestrians and eliminate distractions which could cause injury to AEI personnel or other site workers. ® Test Pit and/or other Excavations. All provisions of the OSHA trenching and excavation standard(29 CFR 1926.650-652)must be followed during excavation activities. This includes all test pit excavation and sampling activities. The estimated location of utility installations, such as sewer,telephone,electric, water lines and other underground installations that may reasonably be expected to be encountered during excavation work,must be determined prior to opening an excavation. A ladder or similar means of egress must be located in excavations greater than 4 feet in depth so as to require no more than 25 feet of lateral travel for employees. No person should be allowed to enter an excavation greater than 5 feet in depth unless the walls of the excavation have been protected using an approved shield(trench box),an approved shoring system,or the walls have been sloped back to an angle of 34 degrees,and the excavation is free of accumulated water. If personnel enter an excavation,the spoils pile and all materials must be placed at least 2 feet from the edge of the excavation to prevent the materials from rolling into the excavation. Personnel must remain at least 2 feet away from the edge of the excavation at all times. Upon completion of a test pit exploration,the excavation should be backfilled and graded. Excavation should never be left open unless absolutely necessary,and then only with proper barricading and controls to prevent accidental injury. ® Underground Utilities and Hazards. The identification of underground storage tanks(USTs),pipes, utilities and other underground hazards is critically important prior to all drilling,excavating and other intrusive activities. In accordance with OSHA 29 CFR 1926.650, the estimated location of utility installations,such as sewer,telephone,electric,water lines and other underground installations that may reasonably be expected to be encountered during excavation work, must be determined prior to opening an excavation. The same requirements apply to drilling operations and the use of soil-gas probes. Where public utilities may exist,the utility agencies or operators must be contacted directly or through a utility-sponsored service such as Dig-Safe. Where other underground hazards may exist, reasonable attempts must be made to identify their locations as well. Failure to identify underground hazards can lead to fire,explosion, flooding,electrocution or other life threatening accidents. AEI Site-Specific Health,Safety and Accident Prevention Plan Page 7 September 4,2008 ❑ Water Hazards and Boat Sampling. The collection of water or sediment samples on or immediately adjacent to a body of water can pose significant hazards. In addition to the slip,trip and fall hazards associated with wet surfaces,the potential for drowning accidents must be recognized. These hazards can be intensified by the use of some PPE,particularly if respiratory protection is worn. HAZARD ASSESSMENT: CHEMICAL HAZARDS AND RELATED CONCERNS(CAL OSHA 8 CCR 5192) ® Chemicals Subject to OSHA Hazard Communication. All chemicals used in field activities such as solvents, reagents, decontamination solutions,or any other hazardous chemical must be accompanied by the required labels, Material Safety Data Sheets (MSDS),and employee training documentation(OSHA 1910.1200). For additional information refer to AEI's Hazard Communication Program contained in the Health and Safety Program manual. ❑ Asbestos. Disturbance of building materials in buildings built prior to 1980 must be evaluated for the presence of asbestos-containing materials by an accredited AEI inspector. The inspection and/or removal of asbestos-based or asbestos-containing building materials is regulated by some major cities and several states. Regulations require individuals who conduct building inspections for the presence of asbestos or collect samples of asbestos containing materials to be licensed or certified. AEI employees must determine the applicability of these regulations prior to any activities involving asbestos. The primary health effects of asbestos exposure include asbestosis(a scarring of the lungs), lung cancer, mesothelioma and other forms of cancer. Exposure to asbestos is regulated by a comprehensive OSHA standard(29 CFR 1910.1001). ❑ BTEX Compounds. Exposure to the vapors of benzene,ethyl benzene,toluene and xylenes above their respective permissible exposure limits (PELs), as defined by the Occupational Safety and Health Administration (OSHA), may produce irritation of the mucous membranes of the upper respiratory tract,nose and mouth. Overexposure may also result in the depression of the central nervous system. Symptoms of such exposure include drowsiness, headache, fatigue and drunken-like behavior. Benzene has been determined to be carcinogenic,targeting blood-forming organs and bone marrow. The odor threshold for benzene is higher than the PEL and employees may be overexposed to benzene without sensing its presence,therefore,detector tubes must be utilized to evaluate airborne concentrations. The vapor pressures of these compounds are high enough to generate significant quantities of airborne vapor. On sites where high concentrations of these compounds are present,a potential inhalation hazard to the field team during subsurface investigations can result. However,if the site is open and the anticipated quantities of BTEX contamination are small(i.e.,part per million concentrations in the soil or groundwater),overexposure potential will also be small. ❑ Carbon Monoxide. Carbon monoxide(CO)is a gas usually formed by the incomplete combustion of various fuels. Welding,cutting and the operation internal combustion engines can produce significant quantities of CO. Amounts of CO can quickly rise to hazardous levels in poorly ventilated areas. CO is odorless and colorless. It cannot be detected without appropriate monitoring equipment. LELJ02 meters and H-Nu/photoionizing detectors are not appropriate for the detection of CO. A direct reading instrument,calibrated for CO,should be used. Common symptoms of overexposure include pounding of the heart,a dull headache,flashes before the eyes,dizziness,ringing in the ears and nausea. These symptoms must not be relied upon in place of an appropriately calibrated monitoring instrument. Exposures should not exceed 15 ppm. Exposures above 15 ppm require the use of supplied air respirators. Air purifying respirators are not approved for protection against CO. ® Chlorinated Organic Compounds. Exposure to the vapors of many chlorinated organic compounds such as vinyl chloride, tetrachloroethene, 1,1,1-trichloroethane,trichloroethene and 12-dichloroethene above their respective permissible exposure limits(PELs) will result in similar symptoms. The actual PELs as set by the Occupational Safety and Health Administration(OSHA)vary depending on the specific compound. Overexposure to the vapor of these compounds can cause irritation of the eyes,nose and throat. The liquid if splashed in the eyes,may cause burning irritation and damage. Repeated or prolonged skin contact with the liquid may cause dermatitis. Acute overexposure to chlorinated hydrocarbons depresses the central nervous system exhibiting such symptoms as drowsiness, dizziness, headache, blurred vision, in-coordination, mental confusion,flushed skin,tremors,nausea,vomiting,fatigue and cardiac arrhythmia. Alcohol may make symptoms of overexposure worse. If alcohol has been consumed, the overexposed worker may become flushed. Some of these compounds are considered to be potential human carcinogens. Exposure to vinyl chloride is regulated by a comprehensive OSHA standard(29 CFR 1910.1017). ❑ Chromium Compounds. Hexavalent chromium compounds,upon contact with the skin can cause ulceration and possibly an allergic reaction. Inhalation of hexavalent chromium dusts is irritating and corrosive to the mucous membranes of the upper respiratory tract. Chrome ulcers and chrome dermatitis are common occupational health effects from prolonged and repeated exposure to hexavalent chromium compounds. Acute exposures to hexavalent chromium dusts may cause coughing or wheezing, pain on deep inspiration, tearing,inflammation of the conjunctiva,nasal itch and soreness or ulceration of the nasal septum. Certain forms of hexavalent chromium have been found to cause increased respiratory cancer among workers. Trivalent chromium compounds (chromic oxide)are generally considered to be of lower toxicity, although dermatitis may occur as a result of direct handling. ❑ Cutting Oils. Cutting oils may produce a condition known as"cutting oil acne," a specific dermatosis associated with prolonged and repeated direct contact. Other problems associated with continued occupational exposure to cutting fluids include allergic skin sensitization,folliculitis and squamous cell carcinoma,due to the presence of nitrosamines. AEI Site-Specific Health,Safety and Accident Prevention Plan Page 8 September 4,2008 ❑ Fuel Oil. See Petroleum Hydrocarbons(PHC) ❑ Gasoline. See BTEX Compounds,and Tetraethyl and Tetramethyl Lead. ❑ Herbicides. Some of the commonly used herbicides present a low toxicity to man. However, other herbicides pose more serious problems. Organophosphorus and carbamate herbicides,if inhaled or ingested can interfere with the functioning of the central nervous system. Many herbicides can be readily absorbed through the skin to cause systemic effects. In addition to being absorbed through the skin, many herbicides, upon contact with the skin,may cause discoloring, skin irritation or dermatitis. Contaminants of commercial preparations of chlorinated phenoxy herbicides such as 2,4,5-T include 2,3,7,8-tetrachlorodibenzo-p-dioxin(dioxin). Dioxin is a known mutagen and a suspect carcinogen. ❑ Hydrogen Sulfide(HzS). Hydrogen sulfide,characterized by its"rotten egg"odor,is produced by the decomposition of sulfur-containing organic matter. It is found in many of the same areas where methane is found such as landfills,swamps,sewers and sewer treatment facilities. An important characteristic of HZS is its ability to cause a decrease in ones ability to detect its presence by smell. So although one may no longer be able to smell it,it could still be present in harmful concentrations. The symptoms of over exposure include headache,dizziness,staggering and nausea. Severe over exposure can cause respiratory failure, coma,and death. The current OSHA PEL is 10 ppm as an 8-hour TWA. The ACGIH TLV is the same. ❑ Lead Paint. The inspection and/or removal,sanding,grinding,etc.of lead-based or lead-containing paints is now strictly regulated by OSHA. States may require individuals who conduct lead paint inspections or collect samples of lead paint to be licensed or certified. AEI employees must determine the applicability of these regulations prior to any activities involving lead paint. For additional health information,see Metal Compounds. ❑ Metal Compounds. Overexposure to metal compounds has been associated with a variety of local and systemic health hazards,both acute and chronic in nature,with chronic effects being most significant. Direct contact with the dusts of some metal compounds can result in contact or allergic dermatitis. Repeated contact with arsenic compounds may result in hyperpigmentation. Cases of skin cancer due to the trivalent inorganic arsenic compounds have been documented. The moist mucous membranes,particularly the conjunctivae,are most sensitive to the irritating effects of arsenic. Copper particles embedded in the eye result in a pronounced foreign body reaction with a characteristic discoloration of eye tissue. Inhalation ofcopper and zinc dusts and fumes above their established PELs may result in flu-like symptoms known as"metal fume fever." Prolonged and repeated inhalation of the dusts of inorganic arsenic compounds above the established PEL may result in weakness,loss of appetite, a sense of heaviness in the stomach and vomiting. Respiratory problems such as cough, hoarseness and chest pain usually precede the gastrointestinal problems. Chronic overexposure to the dusts of inorganic arsenic may result in lung cancer. The early symptoms of lead poisoning are usually nonspecific. Symptoms include sleep disturbances, decreased physical fitness, headache,decreased appetite and abdominal pains.Chronic overexposure may result in severe colic and severe abdominal cramping. The central nervous system(CNS) may also be adversely effected when lead is either inhaled or ingested in large quantities for extended periods of time. The peripheral nerve is usually affected. "Wrist drop"is peculiar to such CNS damage. Lead has also been characterized as a male and female reproductive toxin as well as a fetotoxin. Exposure to lead(Pb)is regulated by a comprehensive OSHA standard(29 CFR 1910.1025). ❑ Methane. Methane is an odorless,colorless,tasteless,gas that cannot be detected by an H-Nu or similar photoionizing detector(PID). When present in high concentrations in air,methane acts primarily as a simple asphyxiant without other significant physiologic effects. Simple asphyxiants dilute or displace oxygen below that required to maintain blood levels sufficient for normal tissue respiration. Methane has a lower explosive limit(LEL)of 5 percent and an upper explosive limit(UEL)of 15 percent. The LEL of a substance is the minimum concentration of gas or vapor in air below which the substance will not burn when exposed to a source of ignition. This concentration is expressed in percent by volume. Below this concentration,the mixture is"too lean"to bum or explode. The UEL of a substance is the maximum concentration of gas or vapor in air above which the substance will not burn when exposed to a source of ignition. Above this concentration, the mixture is "too rich" to bum or explode. The explosive range is the range of concentrations between the LEL and UEL where the gas-air mixture will support combustion. For methane this range is 5 to 15 percent. ® MTBE. Methyl tertiary butyl ether(MTBE)is a volatile,flammable and colorless liquid that is relatively soluble in water. MTBE has a typical odor reminiscent of diethyl ether, leading to unpleasant taste and odor in water. MTBE is almost exclusively used as a fuel component in motor gasoline. The EPA has concluded that available data are not adequate to estimate potential health risks of MTBE at low exposure levels in drinking water,but that the data support the conclusion that MTBE is a potential human carcinogen at high doses. The ACGIH has recommended an exposure limit of 40 parts of MTBE per million parts of air(40 ppm)for an 8-hour workday,40-hour workweek. ❑ Pesticides. Pesticides can be grouped into three major categories:organophosphates,carbonate and chlorinated hydrocarbons. The actual PELs as set by the OSHA,vary depending on the specific compound. Organophosphates,including Diazinon,Malathion and Parathion, are quickly absorbed into the body by inhalation,ingestion and direct skin contact. The symptoms of exposure include headache,fatigue, dizziness,blurred vision, sweating, cramps, nausea and vomiting. More severe symptoms can include tightness of the chest, muscle spasms, seizures and unconsciousness. It should also be noted that the Malathion and Parathion PELs both carry the Skin notation, AEI Site-Specific Health,Safety and Accident Prevention Plan Page 9 September 4,2008 9 indicating that these compounds adversely effect or penetrate the skin. OSHA specifies that skin exposure to substances carrying this designation be prevent or reduced through the use of the appropriate PPE. Chlorinated Hydrocarbons such as Chlordane,DDT and Heptachlor can cause dizziness,nausea,abdominal pain and vomiting. The more severe symptoms include epileptic like seizures,rapid heart beat,coma and death. These compounds also carry the OSHA Skin notation. The symptoms of exposure to carbamate such Carbaryl(also known as Sevin)are similar to those described for the organophosphates. However,the OSHA exposure limit for Carbaryl does not carry the Skin notation. ❑ Petroleum Hydrocarbons (PHCs). Petroleum Hydrocarbons such as fuel oil are generally considered to be of low toxicity. Recommended airborne exposure limits have not been established for these vapors. However, inhalation of low concentrations of the vapor may cause mucous membrane irritation. Inhalation of high concentrations of the vapor may cause pulmonary edema. Repeated or prolonged direct skin contact with the oil may produce skin irritation as a result of defatting. Protective measures,such as the wearing of chemically resistant gloves, to minimize contact are addressed elsewhere in this plan. Because of the relatively low vapor pressures associated with PHCs,an inhalation hazard in the outdoor environment is not likely. ❑ Polychlorinated Biphenyls(PCBs). Prolonged skin contact with PCBs may cause the formation of comedones,sebaceous cysts,and/or pustules(a condition known as chloracne).PCBs are considered to be suspect carcinogens and may also cause reproductive damage. The OSHA permissible exposure limits(PELs)for PCBs are as follows: Compound PEL(8-hour time-weighted average) Chlorodiphenyl(42%Chlorine) 1 mg/m3-Skin Chlorodiphenyl(54%Chlorine) 0.5 mg/m3-Skin It should be noted that PCBs have extremely low vapor pressures(0.001 mm Hg @ 42%Chlorine and 0.00008 mm Hg @ 54%Chlorine). This makes it unlikely that any significant vapor concentration(i.e., exposures above the OSHA PEL) will be created in the ambient environment. This minimizes the potential for any health hazards to arise due to inhalation unless the source is heated or generates an airborne mist. If generated,vapor or mists above the PEL may cause irritation of the eyes,nose,and throat. The exposure limits noted above are considered low enough to prevent systemic effects but it is not known if these levels will prevent local effects. It should also be noted that both PELs carry the Skin notation,indicating that these compounds adversely effect or penetrate the skin. OSHA specifies that skin exposure to substances carrying this designation be prevented or reduced through the use of the appropriate personal protective equipment(PPE). ❑ Polycyclic Aromatic Hydrocarbons(PAHs). Due to the relatively low vapor pressure of PAH compounds,vapor hazards at ambient temperatures are not expected to occur.However,if site conditions are dry,the generation of contaminated dusts may pose a potential inhalation hazard. Therefore dust levels should be controlled with wetting if necessary. Repeated contact with certain PAH compounds has been associated with the development of skin cancer. Contact of PAH compounds with the skin may cause photosensitization of the skin,producing skin bums after subsequent exposure to ultraviolet radiation. Protective measures, such as the wearing of chemically resistant gloves,are appropriate when handling PAH contaminated materials. ❑ Tetraethyl and Tetramethyl Lead. Both compounds are used as anti-knock ingredients in gasoline. The inhalation of tetraethyl lead dusts may result in irritation of the respiratory tract. This dust,when in contact with moist skin or eye membranes,may cause itching, burning and transient redness. The direct absorption of a sufficient quantity of tetraethyl lead,whether briefly at a high rate,or for prolonged periods at a low rate,may cause acute intoxication of the central nervous system. Mild degrees of intoxication may cause headache, anxiety, insomnia, nervous excitation and minor gastrointestinal disturbances. ® Volatile Organic Compounds(VOCs). See BTEX compounds and Chlorinated Organic Compounds. ❑ Waste Oil. See Petroleum Hydrocarbons(PHCs)and Cutting Oil. EMARD ASSESSMENT: BIOLOGICAL HAZARDS AND RELATED CONCERNS(CAL OSHA 8 CCR 5192) ❑ Insects. Insects represent significant sources(vectors)of disease transmission. Therefore,precautions to avoid or minimize potential contact should be considered prior to all field activities. Disease or harmful effects can be transmitted through bites,stings or through direct contact with insects or through ingestion of foods contaminated by certain insects. Examples of disease transmitted by insect bites include encephalitis and malaria from contaminated mosquitoes,lyme disease and spotted fever from contaminated ticks. Stinging insects, such as bees and wasps,are prevalent throughout the country,particularly during the warmer months. The stings of these insects can be painful,and cause serious allergic reactions to some individuals. ❑ Lyme Disease. Lyme disease is an infection caused by the bite of certain ticks,primarily deer,dog and wood ticks. The symptoms of Lyme disease usually start out as a skin rash then progress to more serious symptoms. The more serious symptoms can include lesions, headaches, arthritis and permanent damage to the neurological system. If detected early the disease can be treated successfully with antibiotics. The following steps are recommended for prevention of lyme disease and other diseases transmitted by ticks:a)Beware of tall grass,bushes,woods and other areas where ticks may live;b) Wear good shoes, long pants tucked into socks, a shirt with a snug collar, good cuffs around the wrists and tails tucked into the pants.Insect/tick repellents may also be useful;c)Carefully monitor for the presence AEI Site-Specific Health,Safety and Accident Prevention Plan Page 10 September 4,2008 of ticks. Carefully inspect clothes and skin when undressing. If a tick is attached to the skin it should be removed with fine tipped tweezers. You should be alert for early symptoms over the next month or so. If you suspect that you have been bitten by a tick you should contact a physician formedical advice. ❑ Medical Wastes and Bloodborne Diseases. Any field activity where exposure to medical wastes or other sources of bloodbome pathogens can be reasonably anticipated must be conducted in accordance with the OSHA(29 CFR 1910.1030)Bloodborne Pathogens standard. According to the OSHA definition,Bloodbome Pathogens means pathogenic microorganisms that are present in human blood and can cause disease in humans. These pathogens include but are not limited to hepatitis B virus(HBP)and human immunodeficiency virus(HIi9. Wherever there is a potential for employee skin,eye,mucous membrane,or parenteral(skin or membrane piercing)contact with blood or other potentially infectious sources,employers must develop a Written Exposure Control Plan. ❑ Poisonous Plants. The possible presence of poisonous plants should be anticipated for field activities in wooded or heavily vegetated areas. Poison ivy is a climbing plant with alternate green to red leaves(arranged in threes)and white berries. Poison oak is similar to poison ivy and sumac but its leaves are oak-like in form. The leaves of these poisonous plants produce an irritating oil which causes an intensely itching skin rash and characteristic blister-like lesions. Contact with these plants should be avoided. ❑ Rats,Snakes and Other Vermin. Certain animals,particularly those that feed on garbage and other wastes,can represent significant sources(vectors)of disease transmission. Therefore,precautions to avoid or minimize potential contact with(biting)animals(such as rats)or animal waste(such as pigeon droppings)should be considered prior to all field activities. Rats,snakes and other wild animals can inflict painful bites. The bites can poisonous (as in the case of some snakes), or disease causing(as in the case of rabid animals). Avoidance of these animals is the best protection. ❑ Waste Water and Sewage. Sewage and waste water contaminated with raw, untreated sewage can represent significant sources of bacterial,viral or fungal contamination. Adverse effects,due to contact,can range from mild skin reactions or rashes to life threatening diseases. Diseases are easily transmitted by accidental ingestion or through skin contact,particularly if the skin is broken. Avoidance of direct contact and good personal hygiene are the best protection from these hazards.
