Ms. Flora Darling of KCEHSD approved the workplan by telephone conversation on August 19, 1993. o Exploratory soil borings were drilled and soil samples were collected on August 27, 1993 in conformance with the scope of work outlined in the project workplan. o Soil samples were analyzed for soluble lead. o Data obtained from the investigation were evaluated to assess the presence and/or extent of soluble lead in the soil underlying the shallow disposal system. BSK JOB B93086 - September 28, 1993 & Associates Site Assessment Report - - EMO 50566 Page o This report was prepared presenting our findings and _ conclusions. BACKGROUND INFORMATION Information concerning site location, site description, site geology and hydrogeology, and project history is presented in the following subsections. Project Location The project site is located at 3315 Pierce Road in the City of Bakersfield, Kern County, California. The site is situated east of State Route 99 and north of State Route 178 and is bounded by Pierce Road on the east, by State Route 99 on the west, and by industrial development on the north and south. The site is within Section 23, Township 29 South, Range 27 East, Mount Diablo Baseline and Meridian (see Vicinity Map, Figure 1). Site Description The site is level, paved with asphaltic and Portland cement concrete, and enclosed with chain link fencing. There are three structures on the site. A 4,300 square foot metal warehouse building is located in the northeast portion of the site. The warehouse was vacant at the time of BSK & Associates' (BSK) site reconnaissance on August 5, 1993. Other structures include a metal storage shed located near the northwest corner of the property and a wood-frame garage near the southeast corner of the property. A water well is located at the northwest property corner. The well is not in use and appears to be capped. The site is within the service area of California Water Service Company. Sanitary sewage generated from site operations is discharged into a septic system located on the north side of the warehouse building. According to the owner, the septic system is not connected to the shallow disposal well (see Figure 2). The shallow disposal well (system) is located behind the northwest corner of the warehouse building. The system consists of a two-stage subsurface clarifier system connected to a 4-inch diameter cast iron horizontal discharge pipe. The discharge pipe is buried approximately 3 feet below grade and extends for a distance of approximately 25 feet westward along the north BSK JOB B93086 - September 28, 1993 & Assooates Site Assessment Report - Cull,,,=,Oroperty - EMO 50566 Page q property line. The discharge line is connected to a 4-inch diameter Orangeberg pipe leach line which extends southward for a distance of approximately 90 feet. Site Geology and Hydrology The site is located within the San Joaquin Valley of the Great Valley geomorphic province of California. Near-surface site soils consist of sand and sandy silt which are Quaternary alluvial deposits of the Kern River, located approximately one-half mile east of the site. Well soundings from the on-site water well indicate that first encountered groundwater occurs at a depth of approximately 30 feet below site grade. Regional groundwater flow direction is southwest at a nearly flat hydraulic gradient. Site History Information concerning the site history was obtained from our interview with the property owner, a review of the City Directories at the Kern County Library, and of historical aerial photographs of the site. The site was used tbr agricultural purposes from sometime during the 1930's until 1955. Review of an aerial photograph dated 1937 depicted the site as a small vineyard with what appears to be a single family residence located in the southeast portion of the site. The warehouse structure was constructed on the site sometime during 1955 and has been utilized by various types of businesses since that time. Businesses that have occupied the site since 1955 are presented in Table 1.

Because industrial waste streams commonly consist of organic and inorganic compounds, KCEHSD has required that owners of property known to be equipped with these types of systems demonstrate that the soil beneath the system components has not been impacted by organic and inorganic constituents. The proper~ owners were notified by KCEHSD on March 23, 1993 that, as owners of a property, known to be the site of a shallow disposal well system, they must obtain sludge and liquid samples from the system and analyze the samples for specified organic and inorganic compounds. The property owners retained the services of BSK to conduct a preliminary sampling and testing investigation (preliminary investigation). · . BSK JOB B93086 - September 28, 1993 & Associates Site Assessment Report - Culie A ~perty - EMO 50566 BSK obtained liquid and sludge samples from the clarifiers on April 9, 1993, under the direction of Mr. Terry Gray of KCEHSD. The samples were analyzed by BSK Analytical Laboratories for volatile organic compounds, total petroleum hydrocarbons as gasoline and diesel, total recoverable petroleum hydrocarbons, and CCR Title 22 Metals. In addition, a California Waste Extraction Test (WET) was performed for barium, cadmium, copper, and lead to assess the soluble concentration of these metals. Analytical results of the preliminary testing are presented in Tables 2 and 3. Laboratory test results are presented in Appendix A. ::."'"".' ':::.' ":':.': :i:.::?:' .....:::!.!:?

The property owner requested BSK to prepare a workplan and conduct a site assessment. INVESTIGATIVE PROCEDURES The investigation consisted of field and laboratory studies. Details of each phase are summarized below. Technical procedures used for equipment decontamination, soil sampling, analytical testing, and quality control are presented in Appendix C. Liquid and Sludge Removal Prior to commencement of drilling and sampling, the liquid and sludge contained in the clarifiers · was removed. Because the sludge contained concentrations of soluble lead exceeding the maximum allowable soluble threshold limit concentration (STLC) as determined by using the WET set forth in Cai. Code Regs.,tit.22,§66261.24.(2)(A), liquid and sludge was disposed as hazardous waste. Liquid and sludge was pumped into a vacuum truck by Advanced Cleanup Technologies, Inc. (ACT) of Bakersfield and transported by ACT to the DeMenno/Kerdoon Recycling Facility located in Compton, California. Prior to transport of the hazardous waste, the property owner was assigned an EPA generator identification number and the material was manifested as hazardous waste. A copy of the waste manifest and bill of lading is presented in Appendix D. Exploratory Boring and Sampling Locations Seven exploratory borings were drilled on the site on August 27, 1993. Borings were located adjacent to each clarifier and at 20 toot increments along the leach line. Concrete pavement at the location of the clarifiers was removed by coring. A boring was located approximately 60 feet east of the leach line to obtain a soil sample to be tested for background level of soluble lead at the site. Two undisturbed soil samples were collected at each boring location. Soil samples were collected at depths of one foot and five feet beneath the leach line and clarifiers. Boring and sampling locations are shown on Figure 3. BSK JOB B93086 - September 28, 1993 & Associates Site Assessment Report - Cul~roperty - EMO 50566 Page 8 Laboratory Analysis of Soil Samples Soil samples collected from Boring B-1 at 4 feet, B-2 at 4 feet and 8 feet, B-3 at 4 feet and 8 feet, B-5 at 7.5 feet and 11.5 feet, B-6 at 7 feet and 11 feet, and B-7 at 10 feet were analyzed for soluble lead by the California Waste Extraction Test (WET) Method by BSK Analytical Laboratories. At the request of Ms. Darling of KCEHSD, other soil samples collected during the field investigation were held by BSK for future testing pending analytical results of the aforementioned samples. FINDINGS Soil Profile Site subsurface soils, to the maximum explored depth of 11.5 feet, generally consist of silty sand to a depth of 5 feet underlain by poorly graded sand. Detailed descriptions of soil types are included in the Logs of Borings in Appendix A. Results of Soil Sample Analyses Analytical results of chemical testing of the soil samples submitted for testing revealed soluble lead below the method detection limit of 0.2mg/L. Analytical testing of a background soil sample for soluble lead revealed background levels below the method detection limit. Laboratory documentation is presented in Appendix B. EVALUATION Results of analyses of soil samples collected from beneath the leach line and clarifiers for soluble lead revealed concentrations of soluble lead below the method detection limit in the soil samples tested. Based on the results of the soil samples tested, it would appear that the subsurface soils wellat the site have not been impacted by leachate discharge from the shallow disposal system and that the potential for groundwater degradation resulting from past use of the system is low. BSK lOB B93086 - September 28. 1993 & Associates Site Assessment Report - - EMO 50566 Page 9 CONCLUSIONS On the basis of our evaluation of the findings, we present the following conclusions. o Soil profile at the site consists of silty sand underlain by poorly graded sand to the maximum explored depth of 11.5 feet. First encountered groundwater is believed to occur under unconfined conditions at a depth of approximately 30 feet. Soluble lead was not detected in the soil samples obtained from beneath the leach line and clariflers. o The existing system should be abandoned in conformance with county guidelines. RECOMMENDATIONS BSK recommends that the existing shallow disposal system be abandoned in conformance with county guidelines to prevent future discharges into the system. The clarifiers should be filled to a depth of approximately one toot below slab grade with a clean sand slurry and then sealed with a concrete cap. LIMITATIONS Findings presented in this report are based on data obtained from our field and laboratory investigations. The report does not reflect variations which may exist between exploratory boring locations and sampling points. Such variations cannot be anticipated nor may they be entirely accounted for in spite of exhaustive additional testing. This study was limited to testing for the presence of soluble lead in the soil underlying a shallow disposal well system. Findings presented in this report are valid as of the present. The passage of time. natural processes or human intervention on the property or adjacent properties BSK JOB B93086 - September 28. 1993 ~ & Associates Site Assessment Report - - EMO 50566 Page 10 and changes in government regulations can cause changed conditions which may invalidate the findings and conclusions presented in this report.

Field and laboratory investigations were conducted in accordance with the project workplan and the procedures described below. SOIL SAMPLING Exploratory Boring Locations Exploratory soil borings were drilled at the locations described in the project work'plan. Prior to drilling in paved areas, concrete pavement was removed by coring. Undisturbed soil samples were obtained at each boring location at depths of one to two feet and at five feet below the bottom of the clarifiers and below the invert elevation of the leach line. Soil Sampling Methods A BSK geologist was on site to coordinate the work, to take custody of the soil samples, and to log the soil types encountered during boring operations. Soil types were visually described in accordance with the Unified Soils Classification System and noted on boring logs with penetration blow counts and other pertinent data. BSK JOB 893086 - September 28, 1993 & Associates Appendix C - Field Sampling Procedures Page 2 Drilling was performed using a truck-mounted drill rig equipped with hollow-stem augers. Soil samples were collected with a California split spoon sampler lined with stainless steel tubes and driven through the center of the hollow-stem auger. The lowermost sample tube collected in the split spoon sampler was retained for chemical analyses. Ends of the sample tubes were sealed with Teflon film, covered with plastic caps, labeled, and sealed with a waterproof tape with non-petroleum adhesive. Samples were identified by project number, sample number, date and time of sampling, sampling personnel name, and requested analyses. Soil samples were stored in an ice chest maintained at or near a temperature of 4°C and shipped to BSK's California Department of Health Services Certified laboratory in Fresno, California. Samples were accompanied by a chain-of-custody form. Chain-of-custody documentation included sampler's name, sample identification information, requested analyses, and times and dates of custody transfers. Equipment Decontamination Drill bits, auger flights, and other ancillary drilling and sampling equipment were cleaned with a high pressure hot water washer prior to drilling and between each boring location. Between soil sampling events, samplers were disassembled and washed in a solution of laboratory grade detergent, rinsed with clean water, and reassembled with clean sample tubes to minimize the potential for cross contamination between sampling events. Decontamination methods and equipment used were documented by the field geologist. Soil Cuttings Disposition Soil cuttings generated during boring operations were used to backfill the boreholes, upon completion of each boring. Spent soil samples from laboratory analyses were retained for a period of 30 days from the date of analysis and were disposed of in accordance with applicable state and federal regulations after that time period. Field Logs/Documentation Soil sampling operations, site and equipment conditions, variances from specified sampling procedures, field observations, instrument readings and measurements, equipment and personnel BSK JOB B93086 - September 28, 1993 & Associates Appendix C - Field Sampling aa~Testing Procedures Page 3 decontamination procedures, and soil sampling depths and locations were documented by the field geologist on prepared BSK forms. These forms are retained in the project records. LABORATORY TESTING Laboratory Analyses Soil samples were analyzed for soluble lead by the California Waste Extraction Test (WET) method set forth in Cai. Code Regs.,tit. 3,§66261.126 Appendix II. Laboratory Quality Control Internal quality control checks used by the analytical laboratory to validate data included the following: Calibration Check Standard - A calibration check standard containing all of the analytes to be measured, internal standard, and surrogates was performed at the beginning of each day. Instrument Performance Criteria Instrument performance criteria was demonstrated every 12 hours in conformance with performance criteria defined in EPA methods. Matrix Spike - Matrix spikes to measure analytical accuracy were analyzed at a rate of one for every ten samples analyzed. If calculated spike recoveries did not fall within acceptable ranges, corrective action was taken before further analyses was performed. Analysis of Duplicate Samples - Duplicate samples were analyzed at a rate of one for every ten samples analyzed to measure analytical precision. Control Charts - Control charts prepared for each parameter determined by a method were supplied to each laboratory analyst to assess whether recoveries were within acceptable limits. Internal Standards - A known concentration of internal standard was added to every standard, blank, and sample which was analyzed for organic parameters to compensate for minor fluctuations in instrument response. Surrogate Standards - Samples were spiked with a surrogate closely related to the compound of interest before sample preparation.

Preparation of this workplan was authorized by Mr. and Mrs. John Alippi on August 3~ 1993. Contents of this workplan include purpose and scope, background information, and a technical approach of our proposed field and laboratory investigations. Three report appendices contain Analytical Results (Appendix A), Field Sampling and Testing Procedures (Appendix B) and a Health and Safety Plan (Appendix C). PURPOSE AND SCOPE Purpose of this workplan is to provide the Kern County Environmental Health Services Department (KCEHSD) with a description of the methodology and technical procedures to be utilized by BSK and Associates (BSK) during the proposed site assessment. Scope of BSK's work includes preparation of this workplan and health and safety plan, a field investigation consisting of sampling the soils beneath the existing clarifiers and leach line, analytical testing of soil samples for soluble metals, and preparation of a site assessment report. BSK Job B93086 - August 12, 1993 & Associate_, Workplan and Health and Safe~lan - Cullen Property - EMO 50566 Page 2 - During preparation of this workplan the following tasks were performed: o A meeting was conducted on August 5, 1993 between Mr. and Mrs. John Alippi and BSK to obtain project information and discuss technical work scope alternatives. o Ms. Flora Darling of KCEHSD was contacted by BSK on August 9, 1993 to discuss sampling and testing parameters. o This Workplan and Health and Safety Plan was prepared. BACKGROUND INFORMATION Project Location The project site is located at 3315 Pierce Road in the City of Bakersfield, Kern County, California. The site is situated east of State Route 99 and north of State Route 178 and is bounded by Pierce Road on the east, by State Route 99 on the west, and by industrial development on the north and south. The site is within Section 23, Township 29 South, Range 27 East, Mount Diablo Baseline and Meridian (see Vicinity Map, Figure 1). Site Description The site is level, paved with asphaltic and Portland cement concrete, and enclosed with chain link fencing. There are three structures on the site. A 4,300 square foot metal warehouse building is located in the northeast portion of the site. The warehouse was vacant at the time of BSK's site reconnaissance on August 5, 1993. Other structures include a metal storage shed located near the northwest corner of the property and a wood-frame garage near the southeast ~ee well~ ro er at, r corner of the p p ty.~___A__w _ well is located at the northwest property corner. _is~ ~use and appears to be capped. The site is within the service area of California Water Service Company. Sanitary sewage generated from site operations is discharged into a septic system located on the north side of the warehouse building. The septic system is not connected to the shallow injection well (see Figure 2). The shallow injection well (system) is located behind the northwest corner of the warehouse building. The system consists of a two-stage subsurface clarifier system connected to a 4-inch BSK Job B93086 - August 12, 1993 & Associates Workplan and Health and Safe'lan - Cullen Property - EMO 50566 Page 3 diameter cast iron horizontal discharge pipe. The discharge pipe is buried approximately 3 feet below grade and extends for a distance of approximately 25 feet westward along the north property line. The discharge line is connected to a 4-inch diameter Orangeberg pipe leach line which extends southward for a distance of approximately 90 feet. At the time of our site reconnaissance both clarifiers contained standing water. Site History Information concerning the site history was obtained from our interview with the property owner, a review of the City Directories at the Kern County Library, and of historical aerial photographs of the site. The site was used for agricultural purposes from sometime during the 1930's until 1955. Review of an aerial photograph dated 1937 depicted the site as a small vineyard with what appears' to be a single family residence located in the southeast portion of the site. The warehouse structure was constructed on the site sometime during 1955 and has been utilized by various types of businesses since that time. Businesses that have occupied the site since 1955 are presented in Table 1. Site Geology and Hydrology The site is located within the San ]oaquin Valley of the Great Valley geomorphic province of California. Near-surface site soils consist of sand and sandy silt, Quaternary alluvial deposits of the Kern River which is located approximately one-half mile east of the site. Water well information obtained from California Water Service Company indicates that first encountered groundwater occurs in unconfined aquifer conditions at a depth of approximately 125 feet in the vicinity of the site. x~.~. ~ Project History KCEHSD in conjunction with the U.S. Environmental Protection Agency Region IX, is concerned that disposal of industrial wastewater into shallow injection well systems has the potential to degrade the water quality of the unconfined aquifer which underlies the city and BSK Job B93086 - August 12, 1993 & Associates Work'plan and Health and Safety Plan - Cullen Property - EMO 50566 Page 4 - serves as the primary source of drinking water for the community. Because industrial waste streams commonly consist of organic and inorganic compounds, KCEHSD has required that owners of property known to be equipped with these types of systems demonstrate that the soil beneath the system components has not been impacted by organic and inorganic constituents. The property owners were notified by KCEHSD on March 23, 1993 that, as owners of a · property known to be the site of a shallow injection well system, that they must obtain sludge and liquid samples from the system and analyze the samples for specified organic and inorganic compounds. The property owners retained the services of BSK to conduct a preliminary sampling and testing investigation (preliminary investigation). BSK obtained liquid and sludge samples from the clarifiers on April 9, 1993 under the direction of Mr. Terry Gray of KCEHSD. The samples were analyzed by BSK Analytical Laboratories f~ compounds, total petroleum hydrocarbons as__g_asoline and diesel, to.....~ recoverable petroleum hydrocarbons, and CCR Title 22 Metals. In addition, a California Waste Extraction Test (WET) was performed for barium, cadmium, copper, and lead to assess the soluble concentration of these metals. Analytical results of the preliminary testing are presented in Tables 2 and 3. Laboratory test results are presented in Appendix A. Based on results of the preliminary investigation, KCEHSD requested that the property owners conduct a site assessment study to assess the presence and/or extent of soluble lead in soils underlying the system. The property owner has requested BSK to prepare a workplan and conduct a site assessment. TECHNICAL WORKPLAN Upon approval of this work'plan by KCEHSD, BSK will conduct a field and laboratory investigation to assess the extent of soluble lead in subsurface soils at the location of the on-site system. Technical approach will consist of removing the existing liquid and sludge from the system, drilling exploratory soil borings, obtaining undisturbed soil samples, and analytical testing of soil samples for soluble lead. Descriptions of methodologies for each of these tasks BSK ;rob B93086 - August 12, 1993 & Associate_' Work'plan and Health and Safe~l~lan - Cullen Property - EMO 50566 Page 5 _ are presented in the following subsections. Detailed procedures for soil sampling and analytical testing are included in Appendix B. Liquid and Sludge Removal Prior to commencement of drilling and sampling, the liquid and sludge contained in the clarifiers will be removed. Because the sludge is known to contain concentrations of soluble lead exceeding the maximum allowable soluble threshold limit concentration (STLC) as determined by using the WET set forth in Cai. Code Regs.,tit.22,§66261.24(2)(A), liquid and sludge will be disposed of as hazardous waste. Material will be pumped into a vacuum truck and transported by a licensed hazardous material hauler to the DeMenno/Kerdoon Recycling Facility located in Compton, California. Prior to transport of the hazardous waste, the property owner will be assigned an EPA generator identification number and the material will be manifested as hazardous waste. It will be the responsibility of the property owner to obtain an EPA generator identification number and to sign all manifests. BSK will not be responsible for the transport or disposal of hazardous materials generated as part of the investigation. Field Investigation The field investigation will consist of drilling exploratory borings and obtaining soil samples for analytical testing. A BSK geologist will be on site to coordinate the work, to take custody of the soil samples, and to log the soil types encountered during boring operations. Soil types will be described in accordance with the Unified Soils Classification System. Soil borings will be drilled adjacent to each clarifier and at 20-foot increments along the leach line to assess the presence and extent of soluble lead in the soil beneath the system components. Soil samples will be obtained at depths of one to two feet and at five feet beneath the invert elevations of the components. A soil sample will also be obtained at a depth of one to two feet at a location away from the system and tested for soluble lead to assess the background level of lead at the site. Concrete pavement in the area of the clarifiers will be removed by sawing BSK Job B93086 - August 12, 1993 & Associates Work'plan and Health and Safe~Plan - Cullen Property - EMO 50566 Page 6 - prior to drilling. It will be the responsibility of the property owner to repair the saw-cut areas. Proposed soil boring and sampling locations are shown on Figure 3. Laboratory Investigation Soil samples S-! and S-3 to be obtained from a depth of one to two feet beneath each clarifier and sample S-5 to be obtained at the fn'st location along the leach line will be tested for soluble lead using the WET method. If analytical results indicate levels of soluble lead below the method detection limit at these locations and depths, no further testing of soil samples will be performed and the results will be reported to KCEHSD. In the event that analytical results indicate detectable concentrations of soluble lead in the samples tested, further testing of the remaining soil samples will be performed to assess the presence and extent of soluble lead.. Site Assessment Report Upon completion of the field and laboratory phases of the investigation, a s~essment report will be prepared. The report will include a summary of the analytical data, boring logs, the extent of contamination (if present), a work'plan for additional site characterization (if necessary), and the proposed methodology for abandonment of the system if no significant contamination is found. Project Schedule It is anticipated that the field investigation would commence within one week after approval of this workplan by KCEHSD. Laboratory analysis of soil samples will require approximately ten working days from the time of submittal. A site assessment report will be submitted to the client approximately two weeks after receiving results of the soil analyses. The preliminary project schedule is presented in Table No. 4. LIMITATIONS The scope of work presented in this workplan is based on the assumption that site features and conditions do not deviate significantly from the information provided to BSK by the client. This workplan is presented with the understanding that it is the client's responsibility to transmit the BSK Job B93086 - August 12, 1993 & Associates Work'plan and Health and Safe~Plan - Cullen Property - EMO 50566 Page 7 information contained herein to the appropriate regulatory agency and property owner for approval prior to commencement of our investigation. It will be the responsibility of the client to identify existing underground systems and features prior to commencement of drilling operations. BSK will not be responsible for damage to subsurface features or to the environment resulting from our drilling at locations approved by the property owner. Execution of the scope of work outlined in this proposal may result in the generation of hazardous materials. BSK will not be responsible for the generation, manifestation, transportation, or disposal of hazardous materials. Hazardous materials generated by the work would remain the responsibility of the property owner. This workplan has been prepared in accordance with generally accepted engineering practices for the area, based on the guidelines of federal and local jurisdictions. This workplan has been prepared for the sole use of BSK and our client. No warranties, express or implied, are made.

Field and laboratory investigations will be conducted in accordance with the procedures described below. SOIL SAMPLING Exploratory Boring Locations Exploratory soil borings will be located as described in the project workplan. Prior to drilling in paved areas, concrete pavement will be removed by sawing. Two working days prior to commencement of the work, Underground Services Alert will be notified and on-site underground utilities will be identified and indicated. Undisturbed soil samples will be obtained at each boring location at depths of one to two feet and at five feet below the bottom of the clarifiers and below the invert elevation of the leach line. Soil Sampling Methods A BSK geologist will be on site to coordinate the work, to take custody of the soil samples, and to log soil types encountered during boring operations. Soil types will be visually described in accordance with the Unified Soils Classification System and noted on boring logs with penetration blow counts and other pertinent data. BSK Job B93086 - August 12, 1993 & Associates Appendix B - Field Sampling a~Testh~g Procedures Page 2 _ Drilling will be performed by a truck-mounted drill rig equipped with hollow-stem augers. Soil samples will be collected with a California split spoon sampler lined with stainless steel tubes and driven through the center of the hollow-stem auger. The lowermost sample tube collected in the split spoon sampler will be retained for chemical analyses. Ends of the sample tubes will be sealed with Teflon fLlm, covered with plastic caps, labeled, and sealed with a waterproof tape with non-petroleum adhesive. Samples will be identified by project number, sample number, date and time of sampling, sampling personnel name, and requested analyses. Soil samples will be stored in an ice chest maintained at or near a temperature of 4°C and shipped to BSK's California Department of Health Services certified laboratory in Fresno, California. Samples will be accompanied by a chain-of-custody form. Chain-of-custody documentation will include sampler's name, sample identification information, requested analyses, and times and dates of custody transfers. Equipment Decontamination Drill bits, auger flights, and other ancillary equipment will be cleaned with a high pressure hot water washer prior to drilling and between each boring location. Between soil sampling events, s_amplers will be disassembled and washed in a solution of laboratory grade detergent, rinsed with clean water, and reassembled with clean sample tubes to minimize the potential for cross contamination between sampling events. Decontamination metho~ and equipment used will be documented by the field geologist. Soil Cuttings Disposition Soil cuttings generated during boring operations will be used to baclcfill the boreholes upon completion of each boring. Spent soil samples from laboratory analyses will be retained for a period of 30 days from the date of analysis and will be disposed of in accordance with applicable state and federal regulations after that time period has elapsed. Field Logs/Documentation Soil sampling operations, site and equipment conditions, variances from specified sampling procedures, field observations, instrument readings and measurements, equipment and personnel BSK Job B93086 - August 12, 1993 & Associates Appendix B - Field SampLing ~Festing Procedures Page 3 decontamination procedures, and soil sampling depths and locations will be documented by the field geologist on prepared BSK forms. These forms will be retained in the project records. LABORATORY TESTING Laboratory Analyses Soil samples will be analyzed for soluble lead by the California Waste Extraction Test (WET) method set forth in Cal. Code Regs.,tit.3,§66261.126 Appendix II, Laboratory Quali~ Control Internal quality control checks that will be used by the analytical laboratory to validate data will include the following: Calibration Check Standard - A calibration check standard containing all of the analytes to be measured, internal standard, and surrogates will be performed at the beginning of each day. Instrument Performance Criteria - Instrument performance criteria will be demonstrated every 12 hours in conformance with performance criteria def'med in EPA methods. Matrix Spike - Matrix spikes to measure analytical accuracy will be analyzed at a rate of one for every ten samples analyzed. If calculated spike recoveries do not fall within acceptable ranges, corrective action will be taken before further analyses are performed. Analysis of Duplicate Samples - Duplicate samples will be run at a rate of one for every ten samples analyzed to measure analytical precision. Control Charts - Control charts prepared for each parameter determined by a method will be supplied to each laboratory analyst to assess whether recoveries are within acceptable limits. Internal Standards - A known concentration of internal standard will be added to every standard, blank, and sample which is analyzed for organic parameters to compensate for minor fluctuations in instrument response. Surrogate Standards - Samples will be spiked with a surrogate which is closely related to the compound of interest before sample preparation. _ BSK .rob B93086 - August 12, 1993 & Associate., APPENDIX C HEALTH AND SAFETY PLAN & Associate.~ APPENDIX C LA{i~ HEALTH AND SAFETY P TABLE OF CONTENTS Page INTRODUCTION ................................................. 1 PURPOSE OF HEALTH AND SAFETY PLAN ............................ 1 APPLICABILITY OF THE PLAN ...................................... 1 RESPONSIBILITIES .............................................. 2 Project Manager (BSK & Associates) ............................. 3 Site Safety Officer (BSK & Associates) ............................ 4 Branch Health and Safety Officer (BSK & Associates) ................. 4 Project Personnel (BSK & Associates) ............................ 5 Subcontractor's Safety Representative ............................ 5 JOB HAZARD ANALYSIS .......................................... 6 Lead ..................................................... 6 Noise Hazards ............................................. 6 Drill Rig Hazards ............................................ 7 Underground Utilities and Overhead Obstructions .................... 8 Traffic Hazards ............................................. 8 Personal Protective Equipment (PPE) .............................. 8 Heat Stress Recognition and Control ............................. 9 EXPOSURE MONITORING PLAN ................................... 10 DECONTAMINATION PROCEDURES ................................ 11 SITE CONTROL ................................................ 11 SAFE WORK PRACTICES ........................................ 11 HEALTH AND SAFETY EQUIPMENT LIST ............................. 13 EMERGENCY RESPONSE PLAN ................................... 13 Fire and Fire Extinguishers ................................... 14 Communication (Telephones) .................................. 14 Incident Report ............................................ 14 Operation Shutdown ........................................ 14 SIGNATURE PAGE .............................................. 15 FIGURES Figure 4 .........

BSK Job B93086 - August 12, I993 & Associates_ Appendix C - Health and Saf¢ll~n Page 6 JOB HAZARD ANALYSIS Potential chemical hazards include those associated with exposure to lead in soil. Physical hazards that may be encountered on site include those from drill rig operations, cold or heat stress, noise, underground and overhead utilities, on-site traffic, and equipment failures. Lead Workers may be exposed to lead in soil and dust generated from drilling and sampling operations. 'Exposure to lead should be minimized because of its toxic effect on humans. The current National Institute For Health and Safety (NIOSH) Permissible Exposure Level (PEL) for lead in the breathing atmosphere is <0.01 mg/m3 based on a 10-hour time weighted average (TWA). Principal exposure routes for lead are inhalation, skin or eye contact, and ingestion. Symptoms of lead exposure include: eye irritation, lassitude, and pallor. Skin contact with potentially contaminated soil or groundwater will be minimized by wearing personal protective clothing. Ingestion of contaminated materials will be minimized by good personal hygiene during work (i.e., thoroughly washing face and hands with soap and water before eating or drinking). First aid for exposure to lead is: Eye: Flush the affected eye with water and seek medical assistance if irritation develops. Skin: Remove contaminated clothing and flush contact areas with water and then thoroughly cleanse contact area by washing with soap and water. If irritation develops seek medical attention. Breath: IF VICTI31 IS NOT BREATHING OR IF BREATHING DIFFICULTIES DEVELOP ARTIFICIAL RESPIRATION OR OXYGEN SHOULD BE ADM.hNISTERED BY QUALIFIED PERSONNEL. Swallow: Seek immediate medical assistance. Noise Hazards The primary noise hazard at this site is from the drilling equipment which may produce continuous and impact noise at or above the OSHA PEL in the immediate proximity of the BSK Job B93086 - August 12, 1993 & Associates AppendLx C - Health and Safety Page 7 equipment. Personnel within 25 feet of drill rigs shall wear hearing protective devices (either muffs or plugs). Drill Rig Hazards Safe work practices for drill rig operation include: o When moving a drill rig off-road, pay particular attention to obstacles in the route of travel. Walk the route fa'st. o Providing an assistant to guide the driver when in close proximity to hazards or if clearance is at a minimum. o Setting the brakes and/or blocking the wheels when the mast is raised. o Lowering the mast when moving the rig. o Confn'ming the status of utilities (energized, charged, etc.) prior to drilling. Call Underground Service Alert (800-642-2444) to locate underground utilities. o Considering overhead lines to be energized. Watching for low overhead lines when entering a site; and call the utility for assistance in moving them. o Operating the drill rig at least 15 feet from overhead lines; checking with local utility compames to confirm line voltage and distance requirements. o Clearing the site of obstructions, debris, etc., prior to setting up the drill rig. o Maintaining proper "housekeeping" around and on the drill rig at all times. Tools should be stored in a manner that permits convenient access but also provides for personnel safety. o Keeping platforms, walkways and scaffolding free of obstructions and excess grease or oil that could cause a surface to become slick and dangerous. o Storing gasoline and other flammable substances only in approved storage containers equipped with spark arresters. o Inspecting drill rig equipment prior to starting work; repairing or replacing faulty items. BSK Job B93086 - August 12, 1993 & Associates Appendix C - Health and Safety Page o Handling augers with care. Using proper lifting technique; use a tool - hoist for large or heavy augers. Staying clear of rotating augers and machinery. o Leveling and stabilizing the drill rig prior to raising the mast and prior to drilling. o Watching for slippery surfaces when mounting or dismounting the platform. o Covering or barricading unattended boreholes. o Avoiding drilling during electrical storms. Underground Utilities and Overhead Obstructions BSK will attempt to locate underground utilities prior to the commencement of drilling activities. Resources will include site plans, underground utility diagrams provided by the owner, and hand augering prior to drilling. Care will be exercised when moving the drill rig and other equipment in areas where overhead obstructions are present. Traffic Hazards Traffic cones and/or barricades shall be used to delineate the work/exclusion zone. Personal Protective Equipment (PPE) Minimum PPE for Site Personnel: o Hard hat o Steel-toed boots or shoes o Safety glasses with side shields BSK .lob B93086 - August 12, I993 & Associates Appendix C - Health and Safety Page 9 Work/Exclusion Zone PPE Requirements: o Hard hat o Eye protection (face shield or safety glasses with side shields) o Steel-toed work boots o Hearing protection within 25 feet of operating drilling rig o Work gloves o Coveralls or long-sleeved shirts Based on subjective evidence of contamination, the following would be donned at the discretion of the SSO or PM: o Tyvek coveralls o Chemical-resistant steel-toed boots o Nitrile gloves (drillers can wear under work gloves) o Surgical latex or vinyl gloves (inner) o Half or full face respirators with organic vapor cartridges. PPE may be downgraded from Level "C" to Level 'D' at the discretion of the SSO. Heat Stress Recognition and Control Heat stress is likely to be a significant hazard when ambient temperatures exceed 85°F. Some effects of heat stress include flushed skin, rash, irritability, faintness, or dry, cool skin. Wearing PPE can place a worker at an elevated risk of developing heat stress. This can result in health effects ranging from transient heat fatigue to serious illness or death. Heat stress is caused by a number of interacting factors including environmental conditions, clothing, work load, and the physical condition of the worker. Because heat stress is one of the most common (and potentially serious) illnesses at hazardous waste sites, rest periods, adequate drinking water intake, and regular monitoring for signs and symptoms of distress are vital. Heat-stress monitoring should be conducted if personnel are wearing PPE (including Tyvek-type coveralls) and the ambient temperature exceeds 70 degrees Fahrenheit. If impermeable garments are not worn, monitoring should commence when ambient temperatures exceed 85 degrees. Heat-stress monitoring should be conducted by measuring worker's heart rate at the beginning of each rest period (i.e. during the first minute). The worker's heart rate should not exceed 110 beats per minute during the first minute, and should decrease by 10 beats per minute for each _ lgig] BSK Job B93086 - August 12, 1993 & Associates Appendix C - Health and Safety Page 10 of the following three minutes. If the heart rate exceeds this amount, shorten the next work cycle by a factor of one third and maintain the same rest period. Suggested monitoring frequencies are shown in the following table. Ambient Temp (°F) Not Wearing PPE Wearing PPE 77.5 - 77.5 After each 150 minutes of work After each 120 minutes of work 77.5 - 82.5 After each 120 minutes of work After each 90 minutes of work 82.5 -'87.5 After each 90 minutes of work After each 60 minutes of work 87.5 - 90 After each 60 minutes of work After each 30 minutes of work 90 and above After each 45 minutes of work After each 15 minutes of work When wearing PPE during warm weather conditions, a personal cooling vest or equivalent is recommended. To help prevent heat stress, site personnel shall drink a sufficient quantity of water to maintain their body fluids at normal levels. Daily fluid intake must be approximately equal to the amount of water lost through perspiration. The normal thirst mechanism is not sensitive enough to provide for sufficient consumption of water to replace lost fluids. The following is recommended during warm or hot weather conditions: o Maintain an adequate supply of drinking water at a temperature of 50° to 60°F. o Drink at least 16 ounces of fluid (preferably water or electrolyte replenishing drink) before beginning work. o Drink a cup or more of water or equivalent fluid every 15 to 20 minutes, or during each rest period. A total of 1 to 1.5 gallons of fluid per day are recommended, but more may be necessary depending on physical condition of the worker and ambient temperature. EXPOSURE MONITORING PLAN Heat stress, noise, and chemical exposures may be encountered at this site. Monitoring procedures for these conditions are presented above. Noise levels will not be monitored; personnel will wear hearing protection. BSK Job B93086 - August 12, 1993 & Associates Appendix_ C - Health and Safety PI Page 11 Drilling operations are not expected to generate a sustained dust cloud. If necessary, a water mist may be applied to reduce dust. Unusual or unrecognized odors or other chemical warnings noticed during work activities will result in cessation of work until the hazard is identified and the risk assessed by the SSO. DECONTAMINATION PROCEDURES A high-pressure hot water washer will be used for decontamination of shovels, auger flights, and other equipment. Rubber boots and gloves will be cleaned with a stiff bristle brush, detergent, and water. Tyvek coveralls, disposable gloves, and spent respirator cartridges should be bagged on site and disposed of with drill cuttings. Respirators will be washed, sanitized, and stored in a clean plastic bag or case after each day's work. Each employee will be responsible for cleaning and maintaining his/her respirator. SITE CONTROL Entry into hazardous areas shall be limited to individuals who must work in those areas and are qualified to do so. Authorized visitors may be allowed to enter the exclusion zone only if they have read and understand this document and have agreed to abide by the requirements set forth, have the requisite health and safety requirements, are willing to follow the instructions of the SSO, and have been informed of the potential hazards and risks associated with them. Traffic cones, barricades, and warning tape will be used to delineate an exclusion zone around the drill rig and work area. The exclusion zone should encompass a 25-foot radius around the rig and work area. SAFE WORK PRACTICES The following general guidelines are presented. o Eating, drinking, chewing gum or tobacco, and smoking are prohibited within the exclusion zone. BSK Job B93086 - August 12, 1993 & Associates Appendix C - Health and Safety PI' A Page 17 o 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. o Field crew members should remain aware of potentially dangerous situations (i.e., presence of strong, irritating or nauseating odors). o Prevent, to the extent possible, spillage. In the event that a spill occurs, contain liquid if possible. o Prevent splashing of contaminated materials. o The number of personnel and equipment in the exclusion zone should be minimized, but only to the extent consistent with work force requirements for safe site operations. o Only personnel trained (Title 8, CCR, Sec. 5192) and authorized will be permitted to work in or enter the exclusion zone. o Personal protective equipment shall be used as specified by the SSO. During drilling and sampling activities, the tbllowing safe work practices shall be employed: o Drilling and sampling equipment will be decontaminated before proceeding to the drill site. o At the drilling or sampling site, sampling equipment will be decontaminated after each use. o Work in areas of Iow expected contamination levels should be conducted first where practical. Work upwind of the contaminated area, if possible. o The minimum number of personnel necessary to achieve the objectives shall be allowed within the exclusion zone. o If emergency and backup subcontracted personnel are at the site, they will remain 25 feet upwind from the exclusion zone, where practical. o Unauthorized personnel will remain outside the exclusion zone at all times.
