Background Information Pensinger's Motor Homes at 1770 Golden State Avenue occupies a 3 acre site with approximately 10,500 square feet of structure area. The rear of the site is used as a trailer/RV parking area. A 40 foot by 40 foot concrete slab was used as a trailer washing area. The water generated from the washing flowed into a tank/leach field combination. In November of 1993, the Kern County Environmental Health Services Department (KCEHSD) advised the property owner that the disposal system was classified by the EPA as a Class V Shallow Injection Well. KCEHSD requested the property owner to obtain water and sludge samples from the basin and submit the samples to a certified laboratory for analysis for the presence of organic compounds and metals. B.C. Laboratories in Bakersfield obtained the samples and performed the analytical tests and the results indicated the presence of gasoline, diesel, oil and grease, and some metals. The KCEHSD advised the owner to obtain soil samples from beneath the system and to test for petroleum hydrocarbons and metals. In January 1994, BSK & Associates drilled four sample borings to a maximum depth of 16 feet below grade. BSK stated that "diesel and specific metal compounds exceeding site background levels are present beneath the system at the sample location." ~I 7 'E" STI::::II:::~T · BAKI:::FISI:=IF:::LD. CA 93301 [BO~] :B~::B~480 · fAX [BO5) Mr. Mike Driggs RE: Pensinger Motor Homes November 23, 1994 Page 2 In May 1994, Wilson & Associates, Inc. (W&A) prepared a "Soil Characterization Work Plan" and submitted the Plan to the KCEHS for review. KCEHS approved the Plan in late June, 1994. Generally, the Plan provided for an 'exploration trench', that would result in the removal of the drain pipe, tanks, leach line, as well as any 'contaminated soil'. The base and sidewalls of the trench would be sampled and tested to verify 'successful removal' of any contaminated soils. Exploration Trench The excavation of the drain pipe commenced on or about August 11, 1994. The drain pipe and tanks were removed. Soil samples were collected and delivered to B.C. Laboratories for analysis for copper and lead, as summarized below. Sample No. Location Copper' Lead 08656-1 08656-2 N. Bottom S. Sidewall 7.5 mg/kg 5.8 mg/kg 15.0 mg/kg 10.0 mg/kg The initial excavation determined that a 'drain pipe' running across the property had previously been broken and that the leakage had discolored the soil. Subsequent to August 11, 1994, additional excavations were completed in order to track the 'discolored' soil to the west along the leach field. Sample No. Location Copper Lead 08946-1 08949-2 08946-3 08946-4 08946-5 08946-6 08947-1 Seepage Pit #1, 8'Depth, Bottom Seepage Pit #1, 8'Depth, Side Slope Seepage Pit #2, 10'Depth, Sidewall Leach Line, 30'W. of Seepage Pit #2, 10,Depth Leach Line, 10'W. of Seepage Pit #2, 10'Depth Leach Line, 40'W. of Seepage Pit #2, 10'Depth Leach Line, 20'W. of Seepage Pit #2, 10'Depth 1.6 mg/kg N.D. 2.3 mg/kg 3.0 mg/kg 21.0 mg/kg 82.0 mg/kg 4.6 mg/kg 11.0 mg/kg 10.0 mg/kg 9.7 mg/kg 4.2 mg/kg 9.7 mg/kg 9.8 mg/kg Wet Test 08946-3 Seepage Pit #2, 10'Depth, Sidewall 6.6 mg/kg Mr. Mike Driggs RE: Pensinger Motor Homes November 23, 1994 Page 3 On September 23, 1994, additional soil was removed from beneath Seepage Pit #2, to a depth of approximately sixteen feet, and approximately three feet laterally. A soil sample was procured from the sump bottom, at the outer edge of the excavation, and delivered to B.C. Laboratories for analysis for Lead. The analysis results was "none-detected". Conclusion The site contained three types of materials that may have been the cause of the elevated levels of some metals. The site contained 'Demolition Debris' to depths as great as six feet. This 'debris' appeared to have come from 'earthquake rubble' deposited in the early 1950's. This cause is very remote due to the lack of lead containing materials in the debris. The site contained a broken storm drain line, owned and apparently operated by the City of Bakersfield. The line was repaired prior to backfilling. While the broken line probably contributed to some of the soil staining and contamination, it is doubtful that the lead contamination was totally from the broken storm drain pipe. The water generated from the trailer washing in itself should not have contained any lead containing material. However, some deleterious material may have been poured into the drainage system. The tanks and leach line system were removed form the site, and the water generated from the concrete pad does not drain off the pad into a sub-soil percolation system.

W&A proposes to conduct additional soil characterization associated with the former wash water disposal system at the above referenced facility. These additional assessment activities to determine the lateral limits of lead-containing soils in the vicinity of the leach line from the system's septic tanks were requested by the Kern County Department of Environmental Health Services (KCDEHS) in a letter dated April 25, 1994. W&A proposes to conduct a site characterization consisting of an exploration trench along the entire length of the drain pipe, the two septic tanks in series, and the leach line. This will result in the removal of the drain pipe, septic tanks, and leach line as well as the lead-containing soils. The base and sidewalls of the exploration trench will then be sampled to verify successful removal, and the stockpile of excavated soil will be sampled to determine appropriate disposition. Upon completion of the field activities, and receipt of the laboratory data, W&A will prepare a report of findings documenting the field activities, analytical results, data analysis, conclusions and recommendations for additional activities, if required. 221 ? 'E" STREET ' BAKERSFIELD, CA 93301 BACKGROUND Site Description Mr. Michael Driggs KCDEHS. May 3, 1994-Page 2 The three acre site is located on 1770 Golden State Avenue the city of Bakersfield, Kern County, California (Figure 1). A wash rack, and associated wash water disposal system was formerly operated at the facility (Figure 2). The site is situated within an area of predominantly commercial businesses. The overall site topography is relatively flat with a slight fall to the west-southwest. Project History The site is occupied by a 10,500 square foot building. A trailer washing area is situated adjacent to the northwest side of the building (see Figure 2). Trailers were washed on a 40 foot by 40 foot concrete slab with a grated center drain. Until December 1993, wash water generated from the trailer washing operation drained into a concrete catch basin which discharged into a 500-gallon concrete septic tank. Overflow from the tank discharged into an identical septic tank, which finally discharged into a leach line. The owner has discontinued use of the system. The owner was advised by the KCDEHS that the system may be classified by the U.S. Environmental Protection Agency (EPA) as a Class V shallow injection well, and would be subject to the requirements of the Underground Injection Program (UIP) under which local oversight is provided by the KCDEHS. The KCDEHS requested organic and inorganic analysis of a water and sludge sample from the catch basin. This· analysis indicated the presence of both organic and inorganic compounds in the wash water. Based upon these results the KCDEHS requests a preliminary soils investigation to determine whether these compound were present in the soils beneath the system's components. BSK and Associates, Inc. (BSK) were contracted by Pensinger's to perform a soils investigation consisting of advancing four soil borings (B-1 through B-4) on January 21, 1994 to a maximum depth of 18 feet below ground level (BGL) at the locations shown on Figure 2. Laboratory analysis of soil samples detected only trace concentrations of organic compounds in the soil. However, the metal lead was detected in the sample from 9 feet BGL in boring B-3 at a concentration of 41 mg/kg, and a wet extraction of that sample indicated 1.7 mg/1 of soluble lead (see BSK's Soil Sampling and Testing Report dated March 23, 1994 for a completed discussion of the analytical results). The KCDEHS determined that these concentrations are in excess of those naturally occurring in the soil at the site, and has requested additional site characterization to determine the lateral limits of lead-containing soil in the vicinity of boring B-3 as well a requesting alternatives for abandonment of the system. Mr. Michael Driggs KCDEHS May 3, 1994-Page 3 · W&A proposes to conduct a site characterization consisting of an exploration trench along the entire length of the drain pipe, the two septic tanks in series, and the leach line. This will result in the removal of the drain pipe, septic tanks, and leach line as well as the lead-containing soils. The base and sidewalls of the exploration trench will then be sampled to verify successful removal, and the stockpile of excavated soil will be sampled to determine appropriate disposition. GEOLOGIC SETTING The site is located in a relatively flat area at an elevation of approximately 500 feet above mean sea level in the southern part of the Great Valley geomorphic province. The Great Valley is a north-south trending valley, approximately 400 miles long by 50 miles wide, the southern portion of which is known as the San Joaquin Valley. The surface of the San Joaquin Valley is primarily composed of unconsolidated Quaternary-aged alluvial sediments. Beneath the alluvial sediments are older, predominantly lake bed deposits. These lie unconformably on Miocene and Pliocene-aged marine sediments, which extend to crystalline basement at a depth of approximately 30,000 feet BGL. Geologic deposits in the study area include Pleistocene alluvial sediments of the Kern River Formation, which form a homocline dipping gently to the southwest. The deposits are alluvium consisting of poorly indurated and dissected fan deposits (California Division of Mines and Geology, 1964). Soil borings at the site indicate that the alluvium is characterized by unconsolidated, silty and well graded sands to a depth of 18 feet BGL, which was the greatest depth penetrated in the previous investigation at the site. Surface and groundwater in the San Joaquin Valley is derived predominantly from the Sierra Nevada mountain range to the east, and is transported by five major rivers, the southernmost being the Kern River. The'subject site is located approximately one mile south of the Kern River. The depth to the regional unconfined aquifer is in excess of 100 feet BGL, with the direction of groundwater flow to the southwest (Kern County Water Agency (KCWA), 1992 Report on Water Conditions, Improvement District No.4, February 1993). The nearest known occurrence of perched groundWater is 2 miles to the east-southeast at a depth of 20 feet BGL in the abandoned Kern River channel to the ancient Kern Lake bed (KCWA, 1992 Water Supply Report, May 1993). No perched groundwater is known to exist beneath the subject site. Groundwater was not encountered during previous drilling to a depth of 18 feet BGL at the site. Mr. Michael Driggs KCDEHS May 3, 1994-Page 4 HEALTH & SAFETY PLAN A written Health and Safety plan will be implemented for site work conducted during the field investigations conducted for this project. The purpose of the plan is to provide specific safety procedures to be implemented during the handling of petroleum hydrocarbon contaminated materials. The Health and Safety Plan is required under regulations set forth in Federal OSHA CFR 29 1910.120, since the UST decommissioning laboratory reports documented the presence of potentially hazardous materials at the site. This Health and Safety plan is included as Appendix A,to the work plan. SITE CHARACTERIZATION Exploratory Trenching and Sampling Prior to trenching, Underground Service Alert (USA) will be notified a minimum of 48 hours in advance of excavation activities. The exploration trench will extend to a depth of 12 feet BGL, and a width of 5 feet along the entire length of the drain pipe, the two septic tanks in series, and the leach line. This will result in the removal of the drain pipe, septic tanks, and leach line as well as the lead-containing soils. The base and sidewalls of the exploration trench will then be sampled to verify successful removal, and the stockpile of excavated soil will be sampled to determine appropriate disposition. Soil samples will be collected at 20-foot intervals along the base and sidewalls of the excavation, as well as a sample representative of every 50 cubic yards of excavated soil, and retained in 6-inch by 2.5-inch diameter brass sleeves. The sample sleeves will be sealed with Teflon_ film, capped, security taped, labeled, and placed on ice for transportation to a California Department of Health Services (DOHS) certified laboratory. Strict chain of custody procedures will be utilized for all samples collected to ensure sample integrity and to document sample possession from the time of collection to the final destination. It is estimated that 12 soil samples will be analyzed. Laboratory turn around time for this phase will be 5 working days. If the laboratory results indicate that no additional excavation is required, then the trench will be backfilled with import material and returned to surface grade. Otherwise, the excavation will be deepened or expanded to remove the lead-containing soil, then backfilled. A recommendation for the appropriate disposition of the stockpiled soil will be provided in the report of findings. Laboratory Analysis of soil Samples Soil samples will be sent to a state-certified laboratory for chemical analysis. The soil samples will be analyzed for total lead using USEPA Test Method 6010. Mr. Michael Driggs KCDEHS May 3, 1994-Page 5 REPORT OF FINDINGS A report will be prepared which details the field activities, sampling procedures, analytical results, data analysis, conclusions, and recommendations. Based upon the conclusions, W&A will recommend what further actions, if necessary, should be performed. The report will be prepared under the supervision of a Registered Professional. Certified laboratory reports and chain of custody documents will be included. SCHEDULE OF COMPLETION W&A can mobilize on-site beginning work described in this work plan within approximately one week upon authorization to proceed from Client, and approval of the work plan by the KCDEHS. The projected time. frame for completion of the major tasks is one day for trenching and sampling the borings, one week for laboratory analysis, and two weeks for report preparation once the laboratory analysis has been completed. Thank you for your consideration of this work plan. If you have any questions, or if we can be of service in any way, please contact this office at your convenience.

PURPOSE The purpose of this plan, which was developed specifically for operations at the referenced site, is to assign responsibilities, establish personnel protection standards and mandatory safety procedures, and provide for contingencies that may arise while field operations associated investigating soil and groundwater are being conducted at the site. This plan complies with, but does not replace, Federal Health and Safety Regulations as set forth in 29 CFR 1910 and 1926, California Health and Safety Regulations set forth in Title 8, California Code of Regulations, and guidance established by the California Department of Health Services. This plan is to be used by W&A as a supplement to such rules, regulations, and guidance. APPLICABILITY The provisions of the plan are mandatory for all on-site W&A employees engaged in activities known to be or potentially associated with the presence' of hazardous materials. These activities may include, but are not limited to, mobilization, project operations, and demobilization. Changes and/or unanticipated site conditions may require modification of this Site Health and Safety Plan (SHSP) in order to maintain a safe work environment. Any proposed changes to this plan should be reviewed by the Corporate Health and Safety Officer of W&A, prior to their implementation. If this is not feasible, the project team leader may modify the plan and record all changes in the field log book. Under no circumstances will the plan modifications conflict with Federal, state, or local health and safety regulations. Under 29 CFR 1910.120 (b) (15) W&A is required to notify each subcontractor of the hazardous materials identified by W&A. The acceptance of such responsibility does not and shall not be deemed an acceptance of responsibility for any other health and safety requirements, such as those related to excavating, trenching, Health and Safety Plan Page.9 drilling or backfilling. Each subcontractor shall perform all work in accordance with a Site Health and Safety Plan for its employees, which covers any exposure to hazardous materials which may be present on site. The subcontractor shall hold W&A harmless from, and indemnify it against, all liability in the case of any injury or injury of its own employees. W&A reserves the right to review the subcontractor's Site Health and Safety Plan at any time. W&A reserves the right to suspend the subcontractor's site work and ask the subcontractor's personnel to evacuate the hazard area in the event of grossly inadequate health and safety precautions on the part of the subcontractor or the belief that the subcontractor's personnel are or may be exposed to an immediate health hazard. KEY PERSONNEL AND RESPONSIBILITIES The key personnel and their responsibilities for this project are as follows: Corporate Health and Safety Officer The W&A Corporate Health and Safety Officer (CHSO) for this project is Mr. John Wilson. It is his responsibility for developing and coordinating the W&A health and safety programs.

Health and Safety Plan Page 11 · Implementing the procedures set forth in the SHSP, and reporting any deviations from the procedures described in the Plan to the SHSO and to the CHSO. SITE INFORMATION Ail field activities will take place on the Pengsinger's Motor Homes property. All drilling activities will take place in the daylight hours between 7:00 A.M. and 7:00 P.M. The presence and location of hazardous materials, which are hydrocarbon compounds and metals, has been confirmed through previous investigation. If needed, three blasts of a horn will be sounded for site evacuation. This site information is current and has been verified through analytical testing. HAZARD ASSESSMENT Hazardous Materials Hazardous materials may be a health hazard to site personnel via ingestion, skin absorption, or inhalation. Biohazards or accidental ingestion of contaminants may occur via hand-to-mouth actions. Dust inhalation may also contribute to ingestion of chemical contaminants. During excavation, soil sample collection, and sample preparation, inhalation of contaminant vapors could occur. Skin absorption may occur via contact with contaminated soil and/or ground water. The degree of hazard depends upon the adverse characteristics and toxicity of the chemical contamination, the amount of potential contact, and the exposure time. The greatest potential for chemical hazard to site personnel is during excavation activities. The following substance is potentially a chemical hazard at the subject site: Substances Involved Physical State Petroleum Hydrocarbons Liquid/Absorbed Characteristics Irritant The following materials potentially present at this project site are specified by California Health and Safety Code 25249.5 as recognized and confirmed by the State of California as carcinogenic and/or mutagenic: Petroleum hydrocarbons may contain trace amounts of benzene. Potential Worker Hazards With hydrocarbon-based liquids, contact may result in dermal irritation due to desiccation. Respiration of air laden with Health and Safety Plan Page 12 hydrocarbon vapors may result in oxygen deficiency and/or mucous membrane irritation. Mixtures of air and hydrocarbons exhibit an explosive range thus presenting an explosion hazard. The minor amount of petroleum hydrocarbons detected at the site may contain trace amounts of benzene, a proven human carcinogen. Potential exposure values and limits for benzene are listed in the table below. TABLE 1 - POTENTIAL EXPOSURE VALUES Chemical Highest Conc. IP~ TLV2 IDLH3 Flammable Detected in (electron (ppm) Level Range Samples (ppm) volts) (percent) Benzene ND 0.9245 10 Carcinogen 1.3-7.1 ~Ionization Potential in electron volts (eV) 2Threshold Limit Value as the time-weighted average (TWA) published by the American Conference of Governmental Industrial Hygienists (ACGIH) 3Immediately dangerous to life and health (IDLH) level as published by National Institute of Occupational Safety and Health (NIOSH), Publication Number 85-114, September 1985. ND: non detected Benzene is a colorless liquid with an aromatic odor. It is incompatible with strong oxidizers like chlorine or bromine with iron. The routes of exposure for benzene include inhalation, skin absorption, ingestion, and skin and/or eye contact. Symptoms of exposure to benzene include irritation to the eyes, nose, and respiratory system, giddiness, headache, nausea, staggering gait, fatigue, anorexia, lassitude, dermatitis, and abdominal pain. The potential health hazard from benzene exposure is very remote at this site. Conditions for Suspension~of Operations Site monitoring equipment will include a Photo-ionization detector (PID) or a Flame-ionization detector (FID) during drilling and trenching. Field activities at Level D will be suspended when the continuous FID or PID level in the breathing zone increases to ten times background levels (assuming an ambient range of five to ten ppm). Health and Safety Plan Page 13 Level of Protection The level of Personal Protection Equipment (PPE) needed for this investigation is Level D. Level D PPE includes coveralls, leather boots with steel toes and shanks, eye protection, safety helmet and gloves. If warranted, this Site Safety Plan can be modified for use of Level C situations. Modification to Level B or Level A is beyond the scope for this Site Safety Plan and is not permitted. The criteria for upgrading to Level C PPE is the detection of unknown gasses or vapors in concentrations greater than 10 times background levels or unknown liquids present within the work area. Level C PPE includes Tyvek suits, nitrile gloves and rubber boots, eye protection, hard hat, and a full-face air-purifying respirator with Scott 642-OA-H cartridge-filters or equivalent. Physical Hazards Drilling equipment will be working near buildings and overhead phone lines. Proper precautions required when working around an operating drill rig will be strictly adhered to. All workers will be positioned upwind from drilling equipment at all times. Slips, Trips and Falls All field personnel shall become familiar with the general terrain and potential physical hazards (ravines, potholes, and loose gravel) which would be associated with accidental risk to slips, trips and/or falls. Splashes and SDills Ail field personnel shall wear appropriate chemical resistant gloves and goggles to prevent potential dermal exposure to accident splashes and spills that may occur during excavation of contaminated soil and soil sampling. Sunburn Working outdoors-on sunny days for extended periods of time can cause sunburn to the skin. Excessive exposure to sunlight is associated with the development of skin cancer. Field staff should take precautions to prevent sunburn by using sun-screen lotion and/or wearing hats and long-sleeved garments. Heat Street Heat stress can be a major hazard, especially for workers donning personnel protective equipment (PPE). The same protective materials that shield the body from chemical exposure also limit the dissipation of body heat and moisture. Heat stress can occur very quickly, depending on the work being performed, the ambient Health and Safety Plan Page 14 weather conditions, clothing, and the individual characteristics of the worker. Because heat stress is probably one of the most common (and potentially serious) illness at hazardous waste sites, regular monitoring and other preventive precautions are vital. Heat stress monitoring should commence when personnel are wearing PPE, including Tyvek-type coveralls, and the ambient temperature exceeds 70°F. If impermeable garments are not worn, monitoring should start when the temperature reaches 85°F. The following monitoring program is for workers wearing semipermeable or impermeable encapsulating ensembles when the temperature in the work area is above 70°F: Heart Rate should be measured by the radial pulse during a 30 second period as early as possible in the rest period. The next work cycle should be shortened by one-third while the rest period is kept the same, if the heart rate exceeds 110 beats per minute. If the heart.rate still exceeds 110 beats per minute at the beginning of the next rest period, shorten the following work cycle by one-third. Preventing heat stress is particularly important because once someone suffers from heat stroke or heat exhaustion, that person may be predisposed to additional heat injuries. To avoid heat stress, the following steps may be taken: · Modify work/rest schedules according to monitoring requirements, and mandate slowdowns as needed. · Alternate personnel assigned to particular tasks to minimize over stress at one job function. · Add additional persons to work team, and work during cooler hours, if possible. · Provide shelter or shaded areas to protect personnel during rest periods. · Maintain workers body fluids to ensure that the cardiovascular system functions adequately by having workers drink 16 ounces of fluid (preferably water) before beginning work, and urge workers to drink at least 16 ounces of fluid during each rest period. · Encourage workers to maintain an optimal level of physical fitness. An initial work/rest cycle on one hour ~work and fifteen minutes rest is recommended for protection of staff when the heat stress hazard is high. The recommended' cycle will be adjusted up or down based upon'worker monitoring, environmental conditions, and the Health and Safety Plan Page 15 judgement of the site safety officer. At any time field team members recognize the signs or symptoms of heat stress prior to a scheduled rest period, they will notify, the site safety officer immediately in order that a rest period can be called. Some of the signs and symptoms of heat stress are heat rash, heat cramps, heat exhaustion, and heat stroke. Heat rash is characterized by a decreasing ability to tolerate heat and skin irritation and may result from exposure to heat or humid air. Skin cleanliness and treatment with mild drying lotions are necessary to prevent infection. Heat cramps are caused by heavy sweating with inadequate electrolyte replacement and are characterized by muscle spasms and pain in the hands, feet, and abdomen. Treatment of this disability consists of administering salted liquids orally. Heat exhaustion may result form physical exertion in a hot environment when cardiac output is inadequate to meet increased flow of blood that results from dilation of peripheral blood vessels or dehydration. It is distinguished by pale, cool, moist skin, heavy sweating, dizziness, nausea, and fainting. First aid for heat exhaustion is as follows: 1. Immediately remove victim to support area, or if you are the victim, proceed to the support area. 2. Decontaminate, if practical, before entering support area. 3. Start cooling, but be careful not to cause a chill. 4. If conscious and not in shock, give water to drink slowly. 5. If vomiting, and/or signs and symptoms are not lessening within an hour, call for emergency help and/or transport victim to emergency room. 6. If person is a victim of heat exhaustion, they should not work the remainder of the day. The most serious form of heat stress is heat stroke. This is caused when the temperature regulation fails and the body temperature rises to critical levels. Immediate action must be taken to cool the body before serious injury and death occur. Red, hot, usually dry skin, lack of, or reduced perspiration, nausea, dizziness and confusion, strong, rapid pulse, and coma are the signs and symptoms of heat stroke. First aid for heat stroke is as follows: 1. Immediately move victim to cool, uncontaminated area, the support area, and remove and dispose of victim's chemical-resistant clothing, if wearing any. Health and Safety Plan Pagel6 2. Cool the victim rapidly using whatever means necessary. This can include, but may not be limited to, removing clothing, fanning, and placing in water. 3. Do not give drinking water to victim. 4. Treat for shock, if needed. 5. Transport the victim to a medical facility immediately for further cooling and monitoring of body functions. Cold Stress Cold stress is a particular concern when field activities are performed while the air temperatures at the site are below 40°F. If winds are blowing at 5 mph or grater and/or the weather is damp or wet, cold stress is even more of a potential hazard. Donning of appropriate clothing, having warm shelter readily available, carefully scheduling work and rest periods, and monitoring workers' physical conditions are precautions that will be taken to prevent cold stress. Cold injury (frostbite and hypothermia) may occur if cold stress is not prevented. As a preventive measure, the body core temperature must not drop below 96.8°F. Pain in the extremities is the first early sign of cold stress. Severe shivering sets in when the body core temperature drops below 95°F. If this occurs, work will stop immediately and the affected worker(s) will take a warming break of sufficient duration that the signs and symptoms of cold stress go away. Noise Heavy equipment, such as drilling rigs and excavators, may produce loud noise. The effects of noise can include, but may not be limited to: · Physical damage to the ear, pain, and temporary and/or permanent hearing loss. · Communication interference that may increase potential hazards due to the inability to warn of dangers and the proper safety precautions to be taken. OSHA regulation 29 CFR Part 1910.95 describes an effective hearing conservation program that must be administered whenever noise exposures equal or exceed an S-hour, time-weighted average sound level of 85 dBA (decibels on the A-weighted scale). In addition, if workers are subjected to noise exceeding an 8-hour, time-weighted average sound level of 90 dBA, feasible administrative or engineering controls must be utilized. Health and Safety Plan Page 17 Heavy Equipment and Drilling Before beginning any site work, the drilling subcontractor will perform a safety inspection of the drilling equipment. Personnel shall not work with equipment that they judge to be unsafe because of deterioration, missing parts, obvious defects, or improper use for site conditions. All equipment shall be bonded and grounded, sparkproof, and explosion-resistant, as appropriate. ANSI-approved hardhats must be worn at and near the drill rig or any other heavy equipment. Since heavy pieces of equipment will be used during drilling, steel-toed boots/shoes are required during drilling operations, as well as during operation of other heavy equipment. The driller must maintain a safe clearance (at least 10 feet) between overhead utility lines and the drill rig at all times. Underqround Utilities The general engineering contractor will locate all underground utility locations prior to the starting of drilling activities. Resources used include site plans, utility companies, and Underground Services Alert (USA). In California, USA must be contacted at least two, but not more than fourteen, days prior to drilling on public property. MEDICAL MONITORING Ail W&A employees assigned to the sampling operations must be active participants in W&A Employee Medical Surveillance Program, which meets the requirements of 29 CFR 1910.120. W&A's program requires employees assigned to hazardous waste site investigations and remediation to take pre-assignment, annual, and exit medical examinations. The CHSO will maintain current copies of training certificates and statements of medical program participation for all site personnel. Work-Rest Schedule Depending on the prevailing temperature and humidity, a work-rest schedule may be necessary. Duration and frequency will be at the discretion of the excavator and/or site supervisor. A supply of potable water will be kept available near the site. Safety Trainina Field personnel must receive 40-hour basic health and safety training, designed to comply with the OSHA/EPA requirements for hazardous waste operations and eight hours of annual refresher as set forth in 29 CFR 1910.120, and attend a site-specific safety orientation conducted by the project supervisor. The briefing shall include the following: Health and Safety Plan Page 18 1) 2) 3) 4) 5) 6) A briefing on the work to be performed and the work schedule A discussion of the potential chemical and physical hazards associated with the work to be performed Hazard identification Purpose and limitations of personal protective equipment Decontamination and emergency response procedures Proper on-site conduct. EMERGENCY CONTACT AND PROCEDURES Contacts Should any situation or unplanned occurrence require outside or support services, the appropriate contact from the following should be made: Agency Ambulance Kern County Fire Department Police KCDEHS Person to Contact Dispatcher Dispatcher Dispatcher Mr. Michael Driggs Telephone 911 911 911 (805) 861-3636 Paramedics should be summoned in the event of a serious injury; they will arrange to transport the victim to the nearest appropriate facility. A first aid kit will be available at the site for use in case of minor injuries. If anyone receives a splash or particle in the eye, the portable eyewash will be used to irrigate the eye for 15 minutes. If direct contact with contaminants occurs, affected skin areas should be washed immediately with soap and water. At least one person at the site will have current certification in First Aid and CPR. SITE LAYOUT The level of hazard associated with the work to be performed does not require dividing the site into formal exclusion, contamination reduction, and support zones. However, care will be taken to avoid breathing vaporized petroleum hydrocarbons. CONTAMINATION MONITORING Organic vapor monitoring of the ambient air shall be conducted at reasonable intervals as determined by project personnel. The purpose of monitoring is to determine if vapor levels in the work area are high enough to warrant personal protection measures or evacuation of the site. Organic vapor levels should be monitored using an OVM photoionization meter with an 11.7 eV lamp (probe), calibrated to benzene or a Foxboro_ OVA (organic vapor analyzer) 108 flame-ionization detector calibrated for non-methane hydrocarbons. Health and Safety Plan Page 19 Background should be determined by taking readings before sampling begins. All readings, background and others, must be recorded. If any continuous measurement is observed to be 10 times over background levels in the work area, respiratory protective action will be required. Lesser protective measures are at the field geologists or engineers discretion. DECONTAMINATION Before leaving the site/work area, personnel must remove all protective equipment and wash their hands, faces and necks. These washing procedures shall be observed before all work breaks. To minimize the potential for cross-contamination, all excavation equipment shall be decontaminated before the start of drilling, between borings, and before removal from the site. Sampling equipment shall be decontaminated before sampling and between sampling with washing with laboratory-grade detergent, a water rinse and a contaminant-free distilled water rinse. EMERGENCY PROCEDURES Emergency conditions are considered to exist if: * Any member of the field crew is involved in an aCcident, experiences any adverse effects or symptoms of exposure while on-site; or * A condition is discovered that suggests the existence of a situation more hazardous than anticipated. In the event of an on-site emergency, the procedures described below are to be immediately followed. Personnel on-site should use the "buddy system" (stay in pairs). In the event of a communication breakdown, i.e. radio malfunction or if radios are not available, "buddies" should use prearranged hand signals or other means of emergency signals as follows: * Hand gripping throat - out of air, can't breath. Grip partner's wrist or place both hands around waist - leave area immediately, no debate! * Hands on top of head - need assistance * Thumbs down - no, negative. Health and Safety Plan Page 20 The field engineer or geologist will establish emergency evacuation routes and will make all project personnel awareof these routes prior to the first on-site activities. In the event of an emergency, selection other escape route will be based on the nature of the emergency and wind direction. Visual contact should be maintained between "buddies" on-site, with the team remaining in close proximity in order to assist each other in case of emergencies. In the event that any member of the field crew experiences any adverse effects of symptoms of exposure while on site, the entire field crew should immediately halt work and follow the instructions provided the project supervisor. Se Wind indicators visible to all on-site personnel should be provided by the project supervisor to indicate possible routes for upwind escape. The discovery of any condition that would suggest the existence of a situation more hazardous than anticipated should result in the evacuation of the field team and re-evaluation of the hazard and the level of protection required. In the event an should accident occur, it will be necessary to comDlete an Accident Report Form with the company Safety Officer. STANDARD SAFE-WORK PRACTICES General Eating, drinking, chewing tobacco and smoking are prohibited in the contaminated or potentially contaminated area of where the possibility for the transfer of contamination exists. Avoid contact with potentially contaminated substanCes. Do not walk through puddles, pools, mud, etc. Avoid, whenever possible, kneeling on the ground, leaning or sitting on equipment or ground. Do not place monitoring equipment on potentially contaminated surfaces (i.e., ground, etc.). Ail field crew members should be alert to the presence of strong, irritating or nauseating odors that could indicate a potentially dangerous situation. Other senses should be kept alert to possible hazards as well. Precaution should be taken to prevent spillage. In the event a spillage should occur, the liquid should be contained. Se Health and Safety Plan Page 21 Prevent splashing of the contaminated liquids. Field crew members shall be familiar with the physical characteristics of investigations, including the following: * Wind direction in relation to ground-zero area. * Accessibility to associates, equipment, and vehicles. * Communications. * Hot Zone (areas of known or suspected contamination). * Site access. * Nearest water sources. The number of-personnel and equipment in the contaminated area should be minimized but only to the extent consistent with work-force requirements of safe site operations. All wastes generated during W&A and/or subcontractor activities at the site remain the property of the client.

The work was conducted in conformance with the scope of work discussed with Mr. Michael Driggs of the Kern County Environmental Health Services Department (KCEHSD). BACKGROUND The three acre site is at 1770 Golden State Avenue in the city of Bakersfield (see Figure 1) and is being used by the owner as a recreational vehicle and trailer rental business. The site is occupied by an approximately 10,500 square foot metal building. A trailer washing area is situated adjacent to the northwest side of the building. Trailers are washed on a 40 foot by 40 foot concrete slab (see Figure 2). Until December of 1993, wash water generated from the trailer washing operation drained into a concrete catch basin which discharged into a 500-gallon concrete septic tank. Overflow frOm the tank discharged into an identical septic tank which finally discharged into a leach line. The owner has discontinued use of the system. The owner was advised by the KCEHSD that the system is classified by the U.S. EPA as a Class V Shallow Injection Well and is subject to the requirements of the Underground Injection Program (UIP). Kern County requested the owner to obtain water and sludge samples from the catch basin and to test the samples for the presence of organic compounds and metals in conformance with guidelines set forth under the EPA UIP. Results of analytical tests performed by B. C. Laboratories of Bakersfield, California indicated the presence of gasoline, diesel, oil and grease, and metals in the samples. Based on the results of the preliminary tests, KCEHSD requested the owner to obtain soil samples from beneath the system components and to test for petroleum hydrocarbons and metals. Geotechnical Engineering · Engineering Geology · Environmental Services · Construction Inspection & Testing · Analytical Testing Soil Sampling and Testing Report Shallow Disposal System 1770 Golden State Avenue BSK JOB B94002 March 23, 1994 Page 2 FIELD INVESTIGATION Four soil borings were drilled on the site using a drilling rig equipped with hollow-stem augers on January 21, 1994. Boring B-1 was drilled adjacent to the west septic tank and undisturbed soil samples were obtained at depths of 12 and 16 feet below site grade (two feet and six feet beneath the bottom of the tank). Boring B-2 was drilled adjacent to the east septic tank and soil samples were obtained at 11-1/2 and 15-1/2 feet below grade. Boring B-3 was drilled adjacent to the leach line and samples were obtained at depths of 9 and 13 feet. Boring B-4 was drilled approximately 100 feet northeast of the system and a soil sample was obtained at a depth of · 10 feet for testing to assess background levels of specific metals in the native site soils. Boring locations are shown on Figure 2. Drilling and sampling operations were directed by a BSK geologist who took custody of the samples and visually classified soil types encountered during drilling by the USCS method. Soil types, sampling depths, drilling conditions, and other pertinent information was recorded on field logs by the geologist. Following sampling, the boreholes were backfilled with drill cuttings. Prior to sampling, augers, bits, sampling devices, and other associated equipment were decontaminated by rinsing with a high pressure hot water washer, washed in laboratory grade detergent, and rinsed with potable water. Samples were collected, stored and transported in accordance with guidelines outlined in U.S. EPA Test Methods for Evaluating Solid Waste, Physical/Chemical Methods: SW-846, Third Edition. Chain-of-Custody documentation was maintained during sample collection and transport. LABORATORY TESTING Soil samples were shipped to BSK's state certified analytical laboratory in Fresno, California for testing. Samples obtained from two feet beneath the system and the background sample were analyzed for aromatic hydrocarbons (BTEX), total petroleum hydrocarbons-gasoline (TPH-G), total petroleum hydrocarbons-diesel (TPH-D), arsenic, barium, copper, lead, mercury, nickel, and vanadium by EPA and Department of Health Service approved test methods. Samples obtained from a depth of six feet were held by the laboratory pending test results of the shallow samples. Subsequently, the hold samples from Borings B-1 and B-3 were also tested for BTEX, TPH-G, TPH-D, arsenic, barium, lead, nickel, copper, and mercury. In addition, the sample from Boring B-3 at nine feet was tested for soluble arsenic, lead, nickel, and copper by the California Waste Extraction Test method. SITE OBSERVATIONS Soil types encountered during drilling generally consisted of silty sand underlain by poorly graded sand to the maximum depth explored of 18 feet. Detailed descriptions of soil types are presented on the attached Boring Logs. &Associates Soil Sampling and Testing Report Shallow Disposal System 1770 Golden State Avenue BSK JOB B94002 March 23, 1994 Page 3 ANALYTICAL RESULTS Results of the samples taken at depths of two feet and six feet beneath the system were compared to the results of the background sample.
