Chemicals' Union Avenue Supply Yard to ascertain compliance with Waste Discharge Requirements (WDR) Order No. 80-129 and to become familiar with the site. I was accompanied by Mr. Rex Young of RESNA Industries Inc.. The waste discharge requirements regulate the discharge to a holding facility of wastewater from washdown of chemical mixing facilities and from spillage. According to the WDRs, the. holding facility consists of a concrete pad under the mixing facility with a drain to a concrete lined sump and a large holding tank for most of the washwater, and the wastewater was to be removed to an authorized Class I disposal site. No manufacturing or formulating has occurred at the site since B.C. Chemicals left in 1985. At the time of the inspection, the concrete~lined sump was covered with a grate. Mr. Young indicated the liquid in the sump was rainwater. I did not observe any wastewater discharges or any violations of the WDRs. Assessment reports have been submitted to determine whether previous operations have affected ground water quality. These reports are under review. CONCLUSIONS: I did not observe any wastewater discharges or any violations of the WDRs.

C. CHEMICALS, KERN COUNTY I have reviewed a site assessment report, dated 19 July 1991, that was prepared by Groundwater Resources, Inc. The report provides results of on-site soils assessment work, as proposed in a previously submitted work plan. The goal of this work is to determine whether or not contaminants exist in on-site soils at concentrations that could potentially affect ground water quality and whether or not ground water has been impacted by previous operations at the facility. The regional depth to ground water is expected to be approximately 185 feet and is expected to flow toward the southwest in the vicinity of the site. Beneficial uses of ground water in the Tulare Lake Basin include municipal supply, agricultural supply, industrial service supply, industrial process supply and recreation. The report indicates that soils underlying the site consist primarily of sands and silts with limited amounts of clay. Based on this information, it appears that the vadose zone soils should be able to provide an attenuation factor in excess of 100 but less than 1000 of the total contaminant concentrations found in near-surface soils. Based on the information provided in the report, it appears that organic contaminants are limited to within the first 10 feet of vadose zone soils in those areas that have been sampled. Included in the report are chemical analytical results of surface soils sampled from 10 separate locations of suspected soil contamination at the subject facility (locations $-1 through $-5 and $-7 through $-11 shown on Figure 1, attached). Also included in the report are chemical analytical results of soils obtained from 12 borings placed at areas of suspected soil contamination at the facility (locations B- IOI through B-112 shown on Figure 1). The borings were completed to depths ranging from 40 to 80 feet below ground surface. Samples were obtained from the borings at depths of 5 to 6.5 feet with deeper samples obtained at 5 to 30 foot intervals. The surface soil sampling and boring locations were determined based on available information regarding past operations and based on locations previously sampled by the Department of Health Services. These include areas of previously used sumps, spill areas, and areas of discolored soils. It appears that the locations sampled are appropriate. All samples were analyzed for semivolati1e organics (EPA Method 8270). Selected samples were additionally analyzed for chlorinated hydrocarbons (EPA Method 8120), organochlorine pesticides and PCBs (EPA Method 8080). Further, metals analyses were performed on selected surface soil samples and selected boring samples obtained from between depths of 5 and 10 feet. 1/1/1 . e e B.C. CHEMICALS KERN COUNTY -2- 26 December 1991 B.C. Chemicals handled many different chemicals at the facility, some of which may not have been analyzed for in this phase of the assessment. Based on information in the file and the results of previous sampling of on-site surface soils and wastes previously stored in above-ground containers at the facility, it appears that on-site soils have been analyzed for the contaminants stored or used in the greatest quantities at the facility (e.g. metals, semivolati1e organics, chlorinated hydrocarbons, organochlorine pesticides and PCBs). It therefore appears reasonable to conclude that if the more prevalent contaminants at the site were not detected in the soil samples, then it would be unlikely that the less common contaminants would be detected. Certain quality assurance/quality control (QA/QC) elements proposed in the work plan, such as analyses of field blanks, matrix spikes and method blanks, were not documented in the assessment report. QA/QC information is important to help ensure the integrity of the assessment work. Without this information, coupled with the fact that variations in detection limits were noted in some of the analyses, the question exists as to whether or not the analytical procedures were adequate to detect all possible contaminants at the facil ity. SURFACE SOIL SAMPLING The surface soils analyses show the presence of organic contaminants in two locations (5-2 and 5-3 in Figure 1). The concentrations of organic constituents detected in the surface soil samples exceed the appropriate advisory levels and, in fact, pyrene was detected in one soil sample (5-3) at a concentration of 500,000 times over the advisory level. Using a maximum attenuation factor of 1000, a near-surface soil sample with a contaminant concentration of 500,000 times over the advisory level could still pose a potential threat to ground water quality. Organic contaminants were not detected in the other surface soil sample locations; however, the detection limits for some of the remaining eight surface soil samples were at levels over 20,000 times the corresponding advisory level. Based on a maximum attenuation factor of 1000, these detection limits would allow contaminants to remain in vadose zone soils at concentrations up to 20 times recommended soil cleanup levels. The report indicates that the detection 1 imits were raised because the laboratory needed to dilute the samples to prevent fouling of the analytical equipment from a solute observed in some of the samples. It is understandable that, in certain cases, raising the detection limits may be necessary; however, in situations where the analytical results indicate that no contaminants have been detected but the detection limits have been substantially raised, the question remains unanswered as to whether or not contaminants exist in the soil at concentrations that could affect ground water quality beneath the site. The metals analyses provided in the report show concentrations of several metals at the subject facility. No background metals analyses were provided; however, comparisons made between maximum and minimum concentrations in the samples show elevated concentrations of certain metals in some samples as compared with other samples. Based e e B.C. CHEMICALS KERN COUNTY -3- 26 December 1991 on this comparison, it appears that some of the sampled areas may contain elevated concentrations of metals. Background metals concentrations need to be provided. Two surface soil samples {S-9 and S-10} show what appear to be elevated concentrations of chromium, lead and selenium {as compared with minimum concentrations detected on- site}. Also, selenium was detected in sample S-9 at a concentration in excess of 2 times over the hazardous level designation {TTLC} listed in Title 22, California Code of Regulations. Chromium was detected in S-9 at a concentration of 128 times over the minimum concentration detected. Further, lead was detected in samples $-9 and $-10. Lead was not detected in other surface soil samples and, as such, it appears that the lead concentrations found in $-9 and $-10 may be from previous operations at the site. Information in the file indicates that stormwater runoff from the facility previously collected in a low area between the west side of the property and an adjacent set of railroad tracks. It is reasonable to conclude that this runoff could have contained contaminants from the facility. If contaminated stormwater runoff from the facility has collected in this area, it is possible that contaminants could exist in these soils at concentrations that could potentially affect water quality. As such, it appears appropriate that analyses should be performed on soils from this area. The previously submitted work plan included a proposal to place three borings in this area. However, the report indicates that these borings were not installed. This work still needs to be completed. Certain areas have been identified at the site in which contaminants have been found in soils in concentrations that are below designated levels but above water quality advisory levels. It appears that a potential exists for those contaminants to migrate to other areas and create additional water quality threats. This issue needs to be addressed in the cleanup proposal for the site. VERTICAL EXTENT OF CONTAMINANTS IN THE SOIL PROFILE From boring B-101 {see Figure I}, naphthalene was detected at a concentration of approximately 235 times over the advisory level at a depth of 10 feet. However, naphthalene was not detected at any greater depths and, as such, it appears that naphthalene is limited to the first 10 feet of vadose zone soils in this area. Further, based on an attenuation factor somewhere between 100 and 1,000, it appears that the naphthalene concentration remaining in the vadose zone soils at a 10-foot depth does not pose a substantial threat to ground water quality. In the vicinity of the acid tank containment area, several organic contaminants were detected at a depth of 6.5 feet (in B-104) at concentrations up to approximately 500,000 times over the appropriate advisory levels. Based on an attenuation factor somewhere between 100 and 1000, it appears that the organic contaminants detected at a 6. 5-foot depth cou 1 d pose a potent i a 1 threat to ground water qua 1 i ty. However, organic contaminants were not detected at greater depths in this area and, as such, it appears that organic contaminants are currently limited to the first 6.5 feet of vadose zone soils in this area. e e B.C. CHEMICALS KERN COUNTY -4- 26 Oecember 1991 A sample obtained at a depth of 6.5 feet from boring B-104 shows what appears to be elevated concentrations of chromium and lead (as compared with minimum concentrations detected on-site). As stated previously, elevated concentrations of chromium and lead were also detected in surface soil sample $-9 obtained in the same vicinity as boring B-104. Chromium was detected at a depth of 6.5 feet in boring B-104 at approximately 46 times over the minimum concentration detected of 7.1 mg/kg. Further, a soil sample obtained at a depth of 10 feet from this boring shows chromium at a concentration of approximately 12 times greater than the minimum concentration detected. Metals analyses were not provided for samples obtained at greater depths. It appears that elevated levels of chromium exist in at least the acid tank containment area shown in Figure 1. It appears that additional investigative work needs to be performed in the acid tank containment area, including determining the full vertical extent of metals that were detected in this phase. Background samp 1 i ng for meta 1 s shou 1 d be conducted and a determi nat i on made as to whether or not the concentrations of metals found in on-site soils are greater than the background levels. Information in the file indicates that waste material has previously been buried at the site. Further, it appears that at least some of this material has since been excavated and disposed of. In an attempt to identify possible areas of buried drums, underground storage tanks or other buried objects, the report indicates that a subsurface geophysical investigation was conducted using "total field magnetics and ground penetrating radar." The report indicates that the geophysical investigation could identify subsurface anomalies that could indicate possible areas of buried drums or underground storage tanks. The investigation indicated fourteen separate subsurface anomalies at the facility. Trenches were excavated in three of these anomalies in an attempt to identify the cause. The excavations did not reveal the presence of buried drums, underground tanks or other sources of potential ground water degradation. The remaining anomalies, however, should be investigated further. SUMMARY AND CONCLUSIONS 1. Designated levels of contaminants exist in soils at sampling locations $-3 and $- 9. A work plan for correcting this problem is needed. 2. Due to the following factors, not enough information has been provided to us to know if designated levels of contaminants exist: a. detection limits for samples obtained at locations 5-1, $-4, 5-5, $-7, 5-8, $-9, $-10, and $-11 are at levels up to 20,000 times the corresponding advisory levels; b. information regarding background concentrations has not yet been provided for inorganic constituents detected at sampling locations $-9, $-10, B-101, B- 103, B-104, and B-110; e e B.C. CHEMICALS KERN COUNTY -5- 26 December 1991 c. sampling results of a low area that collects stormwater runoff between the west side of the property and an adjacent set of railroad tracks have not yet been provided. 3. Designated levels do not appear to exist at the remaining locations sampled. 4. The cleanup plan developed for the site should address prevention of water quality problems resulting from runoff of rainwater from any contaminated soils left in place. 3. Although the soil contaminant levels at sampling locations S-2, S-10, B-101, B- 103, 8-104, 8-105 and 8-110 present minimal threat to ground water quality, the concentrations at those locations exceed the Proposition 65 levels. The company may wish to consider the appropriateness of leaving those soils in place. 4. Additional work is needed to determine if buried contaminants are present at the site at concentrations that could affect water quality. JNS:jns/cjs Figure 1 B.C.

Chemicals site. (Item 1.0) 1.2 Soil borings B-104 and B-105 proposed to investigate the suspected sump area, approximately 50 feet west of the warehouse building NO.3, will be positioned within this area to fully assess the potential impacts from the sump. (Item 1.0) 1.3 The ten (10) soil sample locations detailed on the Plot Plan (S-l to -10) will each represent a composite sample of the top 1-1/2 foot of the soil profile. GRI, utilizing a hollow-stem auger drilling rig, will advance a California split-spoon sampler containing three 6" long 2-1/2" in diameter brass cylinders to a depth of 1-1/2 feet. Each cylinder will be capped with teflon-lined caps, sealed with integrity tape, and stored at four degree Celsius prior to transport.

(Item 2.0) 1.4 Off-site assessment borings and monitoring wells will be performed in later stages of the RI/FS should field screening and laboratory results of the samples from the soil composites and borings mandate it. All off-site borings and/or monitoring wells will be strategically positioned to determine the vertical and horizontal extent of migrating soil and groundwater contamination. (Item 3.0) 2.0 CHEMICAL ANALYSIS 2.1 Initially, EPA Method 8015 was to be performed on all soil samples to screen them for non-halogenated volatile organics. However, EPA 8015 will only be performed on samples determined by field screening instrumentation to potentially contain non-halogenated volatile organics; all soil samples transported to a State certified laboratory under a proper Chain of Custody will be analyzed byEPA Method 8270 (extractable semi-volatile organics). EPA Method 8120 (Modified) will be performed on approximately 10 soil samples to test for the presence of chlorinated hydrocarbon compounds. GRI will perform any/all chemical analyses that is deemed necessary to identify known contaminants on the site and their limits. (Items 4.0 & 8.0) e e 3.0 WELL CONSTRUCTION 3.1 Should a water monitoring well be necessary, it will be installed in accordance with Kern County Handbook UT-50. Operations will be suspended and permits obtained from the Kern County Department of Health Services before construction of the well begins. The well will be completed using four-inch PVC casing, with a 15-foot screen at the bottom placed with five feet of the open .interval above the water table and ten feet below. A sand filter pack will be emplaced from total depth to two feet above the perforations, followed by three feet of bentonite seal (See Attached Well Diagram). The hole will then be cemented to the surface. The wellhead will be fitted with a lockable cap and protected with a traffic box set in a cement slab continuous with the annular cement seal. The traffic box will be placed slightly above grade to prevent drainage towards the well. (Item 5.0) 4.0 WELL SAMPLING PROCEDURES 4.1 Prior to any well sampling, water-level measurements will be determined for each well. Measurements will be taken with electrical sounding instruments until two consecutive measurements agree within + 0.01 foot. The top of the casing will be used as the surveyed reference point for all measurements. To reduce the potential for cross contamination between wells, all equipment will be decontaminated after "sounding" each well. (Item 6.0) 4.2 After water-level determinations are made, the wells will be purged at least three well bore hole volumes of water. The water will be stored in DOT approved drums on site prior to chemical analysis and disposal. purging will be accomplished by bailing with a teflon or stainless steel bailer, or a submersible piston pump. A minimum of three samples per well will be collected and field tested for pH, temperature, and electrical conductivity. The parameters will be recorded in afield log. The well will be properly purged when the aforementioned physical parameters have stabilized, signifying that water is being drawn in from the surrounding formation. (Item 6.0) 4.3 After purging is complete, a water sample will be collected using a clear teflon or stainless steel bailer, or submersible piston pump, and stored in a manner to minimize turbulence and the possible loss of volatile constituents. Samples recovered from each well will be decanted into two appropriately prepared 40-ml volatile organic analysis (VOA) bottles. Care will be taken to avoid the presence of headspace in any of the sample bottles. After collection, the sample bottles will be documented under the proper Chain of Custody, placed in e e a sealed ice chest maintained at or below 4 degrees centigrade, and transported as soon as possible to a state of California certified laboratory for analyses. (Item 6.0) 5.0 QUALITY ASSURANCE AND QUALITY CONTROL 5.1 The procedures GRI will follow in the preparation of blind duplicates, field blanks, and spiked samples to assure qu~lity control is detailed in the attached RESNA/Groundwater Resources Inc.'s Quality Assurance and Quali ty Control Plan identified as Appendix C. (Item 7.0) e e APPENDIX C QUALITY ASSURANCE AND QUALITY CONTROL PLAN e e RESNA/Groundwater Resources, Inc. Quality Assurance and Quality Control Plan' The Remedial Investigation (RI) Quality Assurance/Quality Control (QA/QC) program is intended to facilitate the acquisition of accurate and reliable data. Environmental data gathered during the RI will be collected and analyzed following procedures prescribed in the Quality Control Program. A Quality Assurance Program has been established to assure that the Quality Control Program is effective. Both programs are necessary to provide accurate data and documentation for investigations and laboratory analyses. The following field and laboratory procedures will be implemented to ensure that QA/QC objectives are met. 1.0 Recording of Field Data All information pertinent to the field investigation will be kept in a field log book. Information to be documented includes at least the following: - Sample numbers Locations of sample collection Soil boring or well numbers, ~s applicable Depths at which samples were obtained Names of collectors Dates and times of collection Purpose of sample Sample distribution (e.g., laboratory, archive, etc.) Field observations Field measurements (e.g., conductivity, water levels). PID readings, pll, Other data records (e.g. development log, soil sampling report, well log, etc.) 2.0 Sample Containers Groundwater samples will be placed in containers supplied by the analytical laboratory.

Screw on caps will be fitted with teflon liners. Tubes will be tightly capped and sealed. 3.0 Quality Control Field Samples A QC program independent from the laboratory's program will be instituted. The program entails "blind n submittals to the laboratory of blank and duplicate samples. No spiked samples will be supplied from the field for this investigation. The laboratory in-house QC program will include analysis of spiked samples. All QC samples will be assigned independent sample numbers and made indistinguishable from non QC samples. When sampling groundwater, travel blanks will be used to detect the introduction of contaminants during transportation from the field to the laboratory. The travel blanks will be provided by the analytical laboratory. They will be taken to the field and accompany the collected groundwater samples to the laboratory for analysis. The blanks will consist of deionized water and analytically confirmed organic- free water. The blank is numbered, packaged, and sealed in the same manner as the other samples. Ten percent of the water samples submitted to the laboratory for analysis will be duplicates. Water sample duplicates will be created by filling two sample bottles from the well bailer. If more than one bailer volume is required, each bailer volume will be split between containers. 4.0 Sample Preservation Sample containers will be pre-cooled and transported to the si te in the cooler. All samples will be preserved as indicated on Table 1 and placed in a cooler immediately after collection. Chemical ice sealed in plastic bags will be used in the cooler to cool and maintain samples at a temperature of 4·C. A high-low thermometer will accompany the samples to document transport conditions.' Further discussion of samples preservation is included in the sampling protocols (Sections 11 and 12). 5.0 Chain-Of-Custody Procedures 5.1 Sample Labels Each sample container will be labeled prior to filling to prevent misidentification. The label will contain at least the following information: Sample number which uniquely identifies the sample e Hydrocarbon Leak e Table 2 Laboratory Test Methodology Underground Tank Sites Soil Analysis Water Analysis -----------~---------------------------------------------------------- Unknown Fuel Leaded Gas Unleaded Gas Diesel Jet Fuel Kerosene Fuel Oil Chlorinated Solvents Non Chlorinated Solvents Waste Oil or Unknown .

The chain-of-custody record will contain the following information: 1. Site Name 2. Signature of collector 3. Date and time of collection 4. Sample identification number(s) 5. Number of containers in sample set 6. Description of sample and container(s) 7. Name and signature of persons, and the companies or agencies they represent, who are involved in the chain of possession 8. Inclusive dates and times of possession 9. Requested analysis for each sample 5.3 Delivery of Samples to Laboratory Samples will be delivered to the laboratory on a daily basis. Samples will be refrigerated to approximately 4·C for shipping. Shipping containers will be sealed with securi ty tape to assure sample integrity during' shipping. Delivered samples will be accompanied by a chain-of-custody record. The laboratory shall note on the chain-of-custody that samples were properly preserved and security tape was intact upon arrival. 6.0 Sampling and Drilling Equipment Decontamination All equipment used for drilling and sampling will be decontaminated prior to use. All equipment used for collection of more than one sample, such as bailers and spoons, will be decontaminated between each use to prevent cross contamination between samples. Drilling equipment e -- will be decontaminated prior to commencing drilling at each hole. Well construction materials will be cleaned as necessary, prior to installation. Equipment and well material decontamination will be conducted on an impermeable surface and all decontamination effluent will be contained. All surfaces of the equipment will be thoroughly decontaminated using a steam cleaner. The equipment will be placed on a drying rack for air drying. The decontamination water will stored in containers certified for hazardous materials storage and disposed of in an approved manner. Sample equipment to be used for pesticides and organic analysis will be washed in a nonphosphate detergent (Alconox or equivalent) and rinsed with tap water, followed by deionized water and finally with acetone. If the equipment is for metals analysis, the initial rinse will be conducted with 0.1 N nitric acid followed by tap water and deionized water. 7.0 Field Equipment Calibration and Maintenance The following measuring equipment may be used during the Remedial Investigation. Equipment is grouped by field activity. Calibration procedures and frequency are listed for each piece. Soil Borings and Well Dimensions-Steel and coated cloth tape. Calibration: none. Water Level Measurements in Wells- Steel surveyors tape. Calibration: manufacturer supplied temperature correction will be applied as applicable for field conditions. Electrical well sounders.

Groundwater ~ Measurement- standard pH solutions of 4, daily field calibration instructions. Digital pH meter. Calibration: 7, and 10 will be utilized for according to manufacturers Electrical Conductivity- Electrical conductivity meter. Calibration: factory-calibrated annually and periodically calibrated against laboratory prepared standard calibration solution. Water Temperature- Mercury or digital thermometers. Calibration: factory-calibrated once. ------ - combustibl' Gas/Oxygen- Combustible gas/oxygen meter calibration: Factory calibrated, field calibrated monthly, zeroed daily according to manufacturers instructions. Miscellaneous Measuring Devices Calibration procedures for any other measuring device used will be documented at the request of the regulatory authority. All equipment will be checked daily and replaced as necessary. Instrument manuals and an instrument log book will accompany equipment into the field. Any calibration, repairs or related information will be recorded in the log book. 8.0 Laboratory OA/OC Plan Soil and groundwater samples will be submitted to a State Certified Hazardous Waste Laboratory for chemical analysis of hazardous constituents. Established OA/OC procedures for analytical operations will include sample custody procedures, standards of analytical accuracy, analysis of matrix spikes and method blanks, data reduction, verification of raw analytical data, and maintenance of control charts to moni tor analytical performance. These OA/OC procedures are outlined in the laboratory QA/OC Plan which is available upon request. Organic chemical analyses will be performed in conformance with standard procedures established by the United States Environmental Protection Agency (EPA) in "Guidelines Establishing Test Procedures for the Analysis of Pollutants Under the Clean Water Act" (40 CFR Part 136, October 1984). The laboratory is periodically evaluated through external performance audits conducted by EPA and DHS using QC labs. The specific analytical methods to be utilized for purgeable and semivolatile hydrocarbons analyses are shown on Table 2. Provided the data base is of sufficient size, statistical techniques may be employed for data validation. 9.0 Groundwater Monitoring Protocol Moni toring of depth to water and free product thickness within wells at the site will be conducted using an Interface Probe or conductivity meter. For consistency, all measurements will be taken from the north side of the wellhead at the survey mark. To assess potential infiltration of fine grained sediments, total well depth will also be sounded. e Product thickness is calculated by subtracting the depth to product from the depth to water. In addition, water elevations are adjusted for the presence of fuel with the fOllowing calculation: e (Product Thickness) (.8)+(Water Elevation) · Corrected Water Elevation Note. 'I'he factor of 0.8 accounts for the density difference between water and petroleum hydrocarbons. Newly installed wells will be allowed to stabilize for 24 hours after development prior to free product inspection. An acrylic Surface Sampler will be used for visual inspection of the groundwa ter in order to note sheens (diffiCUlt to detect with the Interface Probe), Odors, microbial action and sediments. 'I'he sampler is calibrated in inches and Centimeters for visual inspection of product thickness. '1'0 reduce the potential for cross Contamination between wells, the monitorings will take place in order from the least to most Contaminated. if known. Wells Containing free product will be monitored last. Between each well monitoring the equipment will be decontaminated. Water level data collected from the wells will be used to develop a groundwater contour map for the project site. Groundwater flow will be estimated to be perpendicular to equipotential lines drawn on the map. 10.0 Well Development Protocol Groundwater monitoring wells will be Surged and developed prior to setting the surface seal. Approximately 10 times the volume of water in the casing will be Withdrawn if Possible. Casing volumes will be calculated in the following manner: Volume of Sch~dule 40 PVC Pipe Diameter (inches) I.D.

If the aquifer is slow to recharge, development will continue until recharge is too slow to practically ,continue. The volume of water produced versus time will be recorded. All withdrawn groundwater will be stored on-site in 55 gallon waste drums unless permission is granted by the appropriate regulatory agency to discharge the water to the ground surface or sanitary sewer. Drununed water will be labeled with the source of the water to help ensure appropriate disposal based on contamination levels. 11.0 Soil Sampling Protocol 11.1 Sample Collection During Drilling Activities A proposal will be submitted to the lead Regulatory Authority with proposed boring/sampling locations. The exact location and number of borings at each site will be determined in the field by the Project Geologist/Engineer. Prior to arriving at the sample site, the drill rig/augers will be steam cleaned and all sample equipment will be cleaned. Cleaning will be conducted an-site on all sampling equipment between each sample interval. Soil samples will be obtained using a California modified split-spoon sampler containing three, six inch lang, two inch diameter brass tubes. The sampler will be driven 18 inches ahead of the hallow stem auger by a 140 pound hammer with a 30 inch drop in accordance with American Society for --~- ------------- Testing ae Materials (ASTM) Metho" D 1586-84 for split barrel samp~ing of soil and D 1587-83 for thin-walled tube sampling of soils. The blows required to drive the sampler each six inch interval will be recorded on the boring log. The sampler will be removed from the boring and opened to reveal the brass tubes. The bottom tube will be sealed with aluminum foil and plastic end caps, taped and labeled with the following information: date, time, project 10, sample 10, name of sampler and type of analysis. This sample will be inunediately placed into a cooler containing dry ice or frozen chemical. A "high-low" temperature recording thermometer will accompany sample shipments to ensure proper temperature maintenance. The samples will be delivered to a state certified laboratory following under chain-of- custody protocol within 48 hours of sampling, whenever possible. Soil in the uppermost brass tube will be described according to ASTM standard practice for description and identification of soils (ASTM 0-2488-84). Stratigraphic, genetic and other data/interpretations will also be recorded. Soil properties may also be determined from the middle brass tube and from the sampler shoe. Alternatively the second sample tube may be used with the uppermost tube for preparation of duplicates. These field observations will be noted on a log prepared for each boring/well. Ouring sampling, latex gloves will be worn to prevent cross- contamination with other samples. The disposable gloves will be discarded after collecting samples from each 18-inch sample drive. Soil samples will be collected at five foot intervals, at significant changes in lithology and intervals of obvious contamination in order to develop a complete profile of soil contamination. 11.2 Sample Collection During Tank Removal Soil samples will be collected as soon as possible after removal of the tank. Where feasible, all preparations for soil sampling will be made prior to tank removal. Soil samples collected from a backhoe bucket or directly from the excavation floor will be collected in a thin-walled stainless steel or brass cylinder at least three inches long by one inch in diameter. From 3 to 24 inches of soil will be removed from the immediate surface area where the sample is to be taken and the cylinder then pounded into the soil with a wooden mallet, bulk density driver, or other decontaminated driving device. No head space will be present in the cylinder once the sample is collected. Care will be taken to avoid contamination of both the inside and outside of the cylinder as well as its contents. During _- sampling, . .Latex gloves will be worn to prevent cross contamination with other samples. One pair of disposable gloves will be dedicated to each sample collected. e Once the sample is collected, each end of the cylinder will be sealed with aluminum foil or teflon tape and then capped with a polyethylene lid, taped, and labeled. The sample will then be individually sealed in a ziplock bag and immediately placed in an ice chest containing dry ice or frozen chemical ice for delivery to a state certified laboratory. Sample identification, ~torage and transportation will be conducted as out¡ined in the previous section. 11.3 Sampling from Soil Piles or Shallow Soil Pits Soil samples will be collected and transported from excavated material in the manner described in the previous section, however, a backhoe will not be utilized. If composite samples are collected, four brass cylinders will be collected for every 50 cubic yards of material to be sampled unless otherwise specified by the lead regulatory agency. The samples will be composi ted by the state certified analytical laboratory personnel prior to testing. 12.0 Groundwater Sampling Protocol Prior to arriving at the sampling site, all sampling equipment will be washed with laboratory grade detergent, and rinsed twice with tap water; once with acetone, and once with deionized water. This procedure will be carried out on-site before sampling of other monitoring wells, if more than one well is to be sampled with the same sampling device. Immediately prior to sampling, the depth to water (DTW) in the well will be recorded. The thickness of product on top of the groundwater, if present, will be measured using an interface probe. The procedure for monitoring is presented 1n Section 9.0 (Groundwater Monitoring Protocol). If free product is detected, analysis of groundwater at the interface for dissolved product will not be conducted. A product sample will be collected for source identification. If all free product cannot be removed, an interval specific sampling device may be utilized to collect a sample from below the zone of free product. Before collecting at least two groundwater samples from each well, the well will be purged until indicator parameters (temperature, conductivity and pH) stabilize. This will entail the removal of at least four well casing volumes by bailing or pumping. The cri teria for determining well casing volumes and temporary storage of purged water is outlined in Section 10.0, (Well Development Protocol). The indicator parameter measurements will be taken both before and after purging of each well e casing vol~me. Once the well is purged and indicator parameters have stabilized, a sample will be collected after the water level approaches 80 percent of its initial elevation. Where water level recovery is slow, the sample will be collected after stabilization is achieved and enough water is present to fill sample containers. - Cross contamination from transferring pumps (or bailers) from well to well will be avoided by utilizing dedicated equipment. Where this is not feasible, thorough cleaning of equipment will be performed between sampling rounds. Sampling will proceed from the least contaminated to the most contaminated well, if information is available before sample collection, or if it is indicated by field evidence. Where several types of analysis will be performed for a given well, individual samples will be collected in the following order: 1. Volatile organics 2. Purgeable organic carbon 3. Purgeable organic halogens 4. Total organic carbon 5. Total organic halogens 6. Extractable organics 7. Total metals 8. Dissolved metals 9. Phenols 10. Cyanide The specific analytical methods be utilized for the cOßÙnon volatile/semi volatile to analyses are shown on Table 2. Groundwater samples will be collected with a teflon bailer wi th bottom emptying device. Duplicate samples will be transferred to vials or containers that meet Regional Board specifications (Table 1). Groundwater from the bailer will be transferred to the sample container by allowing the fluid to flow slowly along the sides of the vessel. All containers will be filled above the top of the opening to form a positive meniscus. No head space should be present in the sample container once it is sealed. After the vial is capped it will be inverted to check for air bubbles. If bubbles are present the sample will be discarded and replaced. If it is not possible to collect a sample without head space, the problem will be noted on the field technician's sampling log. Immediately following sample collection, samples will be labeled and stored in an ice chest containing frozen chemical ice sealed in plastic bags. Sample labels will contain the following information: date, time, project ID, sample ID, name of sampler and type of analysis. All samples will be transported under chain-of-custody protocol to a state certified laboratory within 24 hours. A sample container filled in the laboratory with organic free water e- e and carried unopened during the sampling trip will also be provided (Trip Blank). A "high-low" temperature recording thermometer will accompany sample shipments to ensure proper sample temperature maintenance. Samples will be transported either by WaterWork personnel or by private carrier . Analytical holding times will be considered in determining sampling and shipping schedules. Friday shipment/ Saturday laboratory receipt of samples will be coordinated in advanced with the laboratory. NOT TO SCALE LEGEND .

CHEMICALS, KERN DATE: 26 January 1990 BACKGROUND B.C. Chemicals operated a custom chemical mlxlng and supply facility at 1511 S. Union Avenue in Bakersfield. Waste Discharge Requirements, Order No. 80-129, were adopted to regulate wastewater produced by the wash down of chemical mixing facilities and by spillage. The mixing facilities are located on top of a concrete pad which drains to a concrete lined sump. Rinse water generated by the mixing operation was drained to the sump and then pumped to a large holding tank for final disposal to a Class I disposal site. Chemicals manufactured at the facility included solvent emulsion degreasers and formulated oil field chemicals such as acids and caustics. The firm also engaged in the sale of a variety of chemical compounds. These included phosphates I alkalies, alcohols, amines, ammonia, glycol, glycol ethers I glycol ether esters, ketones, chlorinated hydrocarbons, and miscellaneous inorganic compounds. B.C. Chemicals leased the property from the Phoenix Trust. B.C. Chemicals filed for bankruptcy in 1986. Complaints concerning the hand1ing, management, and possible illegal disposal of chemicals at the facility have been filed with the Kern County Health Department (KCHD). The KCHD subsequently has been working with the Phoenix Trust and B.C. Chemicals to assess and clean up the site. Some initial assessment and cleanup work has been completed under the guidance of KCHD. The Regional Board has not received copies of the complaints or reports describing the work completed. Correspondence sent from this office on 29 December 1988 requested that information about the site, including copies of all past and future assessment work plans and reports I be sent to us. In response, we received a geotechnical investigation work plan, submitted by John Minney, Consulting Engineer. This memorandum comprises our review of that work plan. WORK PLAN REVIEW The work plan indicates that approximately 100 drums containing material and several above-ground tanks are currently stored on-site, and there are several areas of potential soil contamination. The work plan specifically addresses assessment of soils at the site, including an assessment of the lateral and I ,,/ / ,;. I -'"/1 I , ..P 1_." e e GEOTECHNICAL INVESTIGATION WORK PLAN REVIEW, B.C. CHEMICALS I KERN COUNTY -2- vertical extent of contamination in the soil to an approximate depth of 30 feet, as well as determination of the soil profile, and sampling and testing protocol. The work plan includes a description of the site. It mentions that the site consists of approximately 2.5 acres and is located in a primarily industrial area. Three buildings are located at the site, as well as approximately 12 large storage tanks and a larger number of "poly" tanks. The work plan indicates that these tanks still contain materia1s, although the materials are not identified. A1so, approximately 100 drums containing a wide variety of unknown chemicals are currently stored at the site. It further indicates that two soil piles, as well as several "roll off" containers for solid waste disposal are present at the site. The work plan indicates that potential soil contamination areas were identified at the site based on observations of areas of crusted sa1ts, surface disco10ration, and low spots. The work plan includes sampling results obtained from previous soils investigations performed at the site, although it does not provide adequate information to determine the sampling locations. The soil sampling results included in the work plan indicate areas where pH > 12.5 and organic constituents have been detected. The work plan states that information exists that indicates past disposal practices at the site may have included one or more buried drum pits and a disposal well. Neither the location of the drum pit nor the disposal well is explicitly stated in the work p1an, other than drums may have been buried at a depth of 20 feet in the rear of the yard. The work plan states that the drums were reportedly buried at the site sometime between 1980 and 1983. It further states that the disposal well is between 100 and 150 feet deep and is unlined. Its location is not indicated. Chemicals were reportedly dumped into the disposal well. The work plan outlines procedures that will be taken to determine the locations of the buried drums and disposal well. The work plan indicates that, as of Spring 1986, the regional depth to ground water is approximately 165 feet, although it has been as shallow as 20 feet (Fall 1939). It further indicates that the principal subsurface materials are stratified Quaternary Alluvium, and the site is located just outside the E-clay layer. The soils range from clay to sand and contain some layers with gravel. The work plan indicates, from information obtained from three nearby wells, that a significant clay strata exists within the top 30 feet of the soil profile. The work plan proposes to drill 15 borings to a depth of thirty feet. These borings would be located at known or suspected areas of previously documented contamination, sumps I spills, leaks, concentrated runoff I and buried drum and disposal well areas. The work plan indicates that the borings would be drilled to 30 feet, as it is expected that a clay layer will be encountered at that depth. In the event that contaminated soils are perceived to be present below this depth e e GEOTECHNICAL INVESTIGATION WORK PLAN REVIEW, B.C. CHEMICALS, KERN COUNTY -3- at the time of the investigation, the borings would be deepened. Ten near-surface soil samples would be obtained from the general yard areas, which would consist of composite samples of the top one foot of soil in each location. The work plan indicates that the principal constituents that would be analyzed for include pH, total hydrocarbons, acid and base neutral extractables, volatile organic compounds, semi-volatile organic compounds, barium, and lead. It indicates that organic compounds will be identified utilizing EPA Methods 8010, 8015, and 8020, with unidentified peaks confirmed with EPA Method 8270. The work plan proposes to initially analyze soil samples obtained at three depths for each boring; one from the ground surface, one from a depth of 5 feet, and one from the anticipated clay layer at a depth of 30 feet. The other soil samples would be held until the initial test results are available. Quality assurance-quality control procedures for collecting and analyzing the soil samples are indicated. Other geotechnical tests would be performed to assess general permeability characteristics, including moisture content, dry density, Atterberg limits, and permeabil ity. The work plan indicates that the subsequent technical report would contain conclusions regarding the soil profile, presence of soil contamination, and the lateral and vertical extent of soil contamination, provided that the lateral extent does not greatly exceed the boundaries of the site, or the vertical extent does not exceed 30 feet. It further indicates that the subsequent technical report would recommend the type of remedial actions, if any, that might be required, including on-site stabilization, recycling, on-site treatment I and off- site disposal. It further states that potential ground water contamination would be addressed by a different consulting engineer (Ken Schmidt, Consulting Engineer). EVALUATION The following deficiencies were noted in the work plan: 1. There is no indication that the boundaries of the vertical and lateral extent of contamination in the soil will be delineated. 2. Procedures to determine whether or not ground water has been adversely affected are not indicated. 3. Although nine samples are proposed to be obtained from each boring, only three soil samples from each boring will be initially analyzed with the remaining samples being held until the initial test results are available. Therefore, it is possible that the holding times may be exceeded for those soil samples that are not proposed to be analyzed initially. e e GEOTECHNICAL INVESTIGATION WORK PLAN REVIEW, B.C. CHEMICALS I KERN COUNTY -4- 4. Sample extraction procedures are not discussed. 5. There is no indication that completed chain of custody forms and laboratory data sheets will be included in the technical report. CONCLUSION Because of the deficiencies indicated above, it appears that modifications are needed in the plan. JNS:cjs 1 ISAAC M.

SO fS¿\.C::", (1.. S{I ¡ lcd, Date : Time : Place: 17 18 19 This Stipulation is entered into by and between Robert 20 21 L. Williams, Esq., the trustee for the estate of B.C. Chemicals, 22 Inc. (hereinafter the "Trustee"); Wells Fargo Bank (formerly Bank 23 of America), as Trustee of The Phoenix Trust (here~nafter "Phoenix 24 Trust"); and Coskey, Coskey & Boxer (hereinafter "Coskey") with 25 reference to the following facts and recitals: On July 18, 1985, B.C. Chemicals, Inc. (hereinafter A. 26 27 "B.C.") filed a petition for relief under chapter 11 of the Bank- 28 ruptcy Code, thereby commencing this case. At the time of the £.1k\,,·1 ~ L23-2492 Stip.Pld \I e e 'H 'I.\.,~ 1 filing, B.C. operated a chemical business at 1511 South Union Ave- 2 nue in Bakersfield, California (hereinafter the "Premises"). B.C. 3 leased the Premises from Phoenix Trust. During the course of its 4 business operations, B.C. supplied a wide variety of chemicals to 5 commercial customers and B.C. accumulated numerous drums, barrels, 6 and other containers containing various types of chemicals on the ' 7 Premises. 8 B. On September 10, 1985, during the pendency of 9 B.C.'s chapter 11 case, the Kern County Health Department (herein- 10 after "Health Department") cited B.C. for numerous violations of 11 California law respecting the management, storage, and disposal of 12 hazardous wastes located on the Premises. Among the violations, 13 B.C. was cited for illegally disposing of hazardous waste. The 14 Health Department ordered B.C. to submit a site cleanup plan and, 15 upon approval of the plan by the State Department of Health Ser- 16 vices and the Health Department, to initiate the cleanup process 17 set forth in the plan. 18 C. On September 26, 1985, B.C. voluntarily converted 19 its chapter 11 case to a proceeding under chapter 7 of the 20 Bankruptcy Code, and the Trustee was appointed. Thereafter, the 21 Trustee, with the approval of the Court, retained the services of 22 EMCON Associates to prepare the site cleanup plan. Subsequently, 23 the plan formulated by EMCON was approved by the Health Department 24 and the State Department of Health Services. 25 D. By order entered in November 1986, entitled "Order 26 on Petition for Authority to Clean Up Premises" (the "First 27 Order"), the Court authorized the Trustee to expend up to $350,000 28 for the cleanup of the Premises and that, if necessary, the EX H1ltl ~ ~., ,~ \1 e e 'H 1 Trustee would return to the Bankruptcy Court for further 2 authorization for the expenditure of funds to clean up any 3 remaining toxic waste problems on the Premises. Coskey appealed 4 to the District Court from the First Order, and the District Court 5 remanded the matter to the bankruptcy court for further 6 proceedings. 7 ' E. By order entered in October, 1987, entitled "Order 8 Re Trustee's Application for Authorization to Clean Up Toxic Waste 9 Premises" (the "Second Order"), a copy of which is attached as Ex- 10 hibit "A", the Court authorized the Trustee to expend, without 11 further order of the Court, up to $350,000 to remove various 12 drums, barrels, and other containers containing hazardous chemi- 13 cals from the surface of the Premises. Coskey appealed from the 14 Second Order. 15 F. By order entered in November, 1987, entitled "Order 16 on Petition for Authorization of Certificate of Deposit" (the 17 "Third Order"), a copy of which is attached as Exhibit liB", the 18 Bankruptcy Court authorized Phoenix Trust to deposit $350,000, in 19 the form of a certificate of deposit, as collateral pending the 20 àppeal of the Second Order by Coskey, so that if the Second Order 21 was ultimately reversed or modified, the Trustee was authorized 22 "to draw on said certificate of deposit up to the amount by which 23 money necessarily expended for cleanup of [the Premises] exceeds 24 the amount of expenditures for cleanup authorized by a final order 25 of the Court, not to exceed $350,000." coskey appealed from the 26 Third Order as well. 27 G. The Second Order was affirmed by a decision of the 28 District Court dated April 24, 1989, a copy of which is attached U.uJ!l A I.) .' .~ e e 1 as Exhibit "C". In that order, the District Court determined, 2 inter alia, that, "the Bankruptcy Court properly determined that 3 the expense to clean up toxic waste on the surface on the property 4 previously leased by the Debtor is a priority administrative ex- 5 pense." By a decision dated the same date, a copy of which is 6 attached as Exhibit "D", the District Court also affirmed the 7 Third Order. 8 H. Coskey has appealed from the orders of the District 9 Court described in Paragraph G, above. Those appeals are current- 10 ly pending in the United states Court of Appeals for the Ninth 11 Circuit as Case Nos. 89-15632 and 89-15635, and are hereinafter 12 referred to collectively as the "Appeals." 13 I. Phoenix Trust has filed two proofs of administra- 14 tive claim against the estate of B.C., copies of which are at- 15 tached hereto as Exhibits "E" and "F", respectively. The first 16 proof of claim asserts an administrative claim for any costs of 17 cleanup of the Premises, and estimates that the cost of cleanup 18 for which an administrative claim is asserted ranges from $400,000 19 to $1.7 million. The second proof of claim asserts administrative 20 claims for monthly rent under the lease of the Premises, as well 21 as the aforesaid cleanup costs. These claims are hereinafter re- 22 ferred to collectively as the "Proofs of Claim." 23 J. Coskey and the Trustee each dispute the claims as- 24 serted by Phoenix Trust. 25 K. Coskey asserts administrative claims against the 26 estate of B.C. for services rendered as counsel to the Creditors' 27 Committee in the chapter 11 case and also for services which it 28 has rendered in litigating the matters described in Paragraphs D-H EXHI!t'" A It), t\ ;. e e 1 above and related matters respecting the estate's alleged respon- 2 sibility for" cleanup of the Premises. Coskey has previously been 3 awarded the sum of $12,399.66 on account of fees and costs as 4 counsel for the Creditors' Committee. In addition, Coskey con- 5 tends that its services have made a substantial contribution to 6 the estate, and have conferred upon the estate a substantial 7 benefit. 'These claims are subject to determination by the Court. 8 L. The Trustee has represented that the cash and cash 9 equivalents now held by the estate of B.C. total approximately 10 $610,000. 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 M. It is the desire of the parties to resolve their disputes regarding the amount and priority of the claims of Phoe- nix Trust, and the timing of the payment of those claims vis-a-vis other administrative claims, on the terms and conditions set forth below. N. The parties have attempted to negotiate, among other things, the appropriate amount to be paid to the Phoenix Trust in settlement of its claims. Coskey preferred a settlement proposal whereby the Phoenix Trust would receive $387,500, plus the following: In the event that the sum of the cash and cash equivalents held by the estate as of the date the Trustee executes this Stipulation and any cash and cash equivalents thereafter received by the estate from any source exceeds $625,000, the Trustee would pay twenty-five percent of such excess to Phoenix Trust, but could offset, against any payment out of such excess, up to twenty-five percent of the amount of such administrative claim for previously unpaid fees and expenses as is awarded to Coskey by the Bankruptcy Court. The Trustee, however, prefers a EX....B~T A ~} " " e e 1 settlement whereunder the Phoenix Trust would be paid a flat sum, 2 $395,000, in-satisfaction of its claims, so as to avoid the 3 administrative complications entailed in the formula described in 4 the previous sentence. Coskey has no objection to proceeding 5 along the lines preferred by the Trustee. 6 O. This stipulation represents a compromise of disput-' 7 ed claims, and the parties' agreement to the terms hereof shall in 8 no manner be deemed to be an admission, express or implied, of 9 liability by any party to any other person or entity, or of any 10 fact, other than the facts set forth in Paragraphs A through L 11 hereof, or the admission of the merits of the position taken by 12 any party hereto with respect to any dispute described above, or 13 any other dispute. 14 NOW, THEREFORE, IT IS HEREBY STIPULATED by and between 15 the parties hereto as follows: 16 1. As used herein, the term "Effective Date" means the 17 later of the following two dates: 18 a. The eleventh day following the date upon which 19 the Bankruptcy Court enters an order approving, and authoriz- 20 ing the Trustee to enter into, this stipulation; and 21 b. The eleventh day following the date upon which 22 the Kern County Superior Court, Proceeding No. 202010, enters 23 an order approving, and authorizing Phoenix Trust to enter 24 into, this Stipulation. 25 2. Within five days following the Effective Date, 26 (a) the Trustee shall pay to Phoenix Trust, by certified or cash- 27 ier's check, and without offset or deduction of any kind, the sum 28 of Three Hundred Ninety-Five Thousand Dollars ($395,000); and EXH"rr A. 1.'. '. e e 1 (b) any certificate of deposit provided by Phoenix Trust under the 2 Second Order-- shall be returned to Phoenix Trust, free and clear of 3 any claims or liens of the Trustee or any other person or entity. 4 3. Within five business days following the receipt of 5 the $395,000 described in Paragraph 2, Phoenix Trust shall with- 6 draw the Proofs of Claim. 7 ' 4. At or before the time of the payment provided in 8 Paragraph 2, the Trustee shall pay to Coskey the amount of such 9 administrative claim as the Bankruptcy Court allows to Coskey for 10 fees and expenses not previously paid to Coskey. 11 5. Within five days following the Effective Date, Cos- 12 key shall file with the United States Court of Appeals for the 13 Ninth Circuit a dismissal with prejudice of the Appeals, providing 14 that each party shall bear its own costs in connection therewith. 15 6. Subject to the proviso contained in the last sen- 16 tence of this paragraph, effective only upon the timely receipt by 17 Phoenix Trust of the $395,000 provided for in Paragraph 2 (which 18 sum shall be deemed to have been received only when the check 19 therefor is honored in good funds), Phoenix Trust, Coskey, and the 20 Trustee (on his own behalf and on behalf of the estate of B.C.) 21 hereby release one another from any and all claims, demands, 22 debts, liabilities, and obligations, known or unknown, contingent 23 or fixed, liquidated or unliquidated, arising out of any fact, 24 matter, occurrence, or transaction occurring prior to the date on 25 which this Stipulation is executed, including, but not limited to, 26 the claims of Phoenix Trust asserted in the Proofs of Claim. Pro- 27 vided, however, that this release shall not apply to: (a) any 28 obligations or claims arising under this stipulation, including, EXtUß¡T A .,. ,. e e 1 without limitation, any claims of Phoenix Trust under Paragraph 2 2 hereof; and {b) any administrative claim of Coskey for fees and 3 expenses in such amounts as are awarded by the Bankruptcy Court. 4 7. The parties to this stipulation hereby waive the 5 provisions of section 1542 of the California civil Code, and any 6 similar principles of law or equity. section 1542 provides as 7 follows: 8 A general release does not extend to claims which the creditor does not 9 know or suspect to exist in his fa- vor at the time of executing the 10 release, which if known by him must have materially affected his settle- 11 ment with the debtor. 12 8.

The parties to the Stipulation include Movant: Wells 6 Fargo Bank (formerly Bank of America), as trustee of the Phoenix 7 Trust (hereinafter "Phoenix Trust"); and the law firm of CoskeYI 8 coskey & Boxer (hereinafter "Coskey"), which acted as counsel to 9 the creditors' committee in the superseded chapter 11 case herein 10 The Stipulation is being filed with the Court contemporaneously 11 with the filing of this Notice of Motion and Motion, and a copy 0 12 the Stipulation will be provided to any party who makes a written 13 request for same to Movant at the address indicated on the captio 14 of this pleading. 15 NOTICE IS FURTHER GIVEN that, pursuant to Local Bank- 16 ruptcy Rule 3(B) (3) of the Local Rules of the United States Bank- 17 ruptcy Court for the Eastern District of California I opposition, 18 if any, to the granting of this Motion must be in writing and mus 19 be served and filed with the Clerk of the Court by any responding 20 party not less than five (5) court days proceeding the date sched 21 uled for the hearing on this Motion. Failure to timely file a 22 written opposition may be deemed a waiver of any opposition to th 23 Motion. 24 This Motion is based on the following facts and grounds 25 1. On July 18, 1985, B.C. Chemicals I Inc. (hereinafte 26 "B.C.") filed a petition for relief under chapter 11 of the Bank- 27 ruptcy Code, thereby commencing this case. At the time of the 28 filing, B.C. operated a chemical business at 1511 South Union Ave -2- 1 determined that the expense to clean up toxic waste on the su~face 2 on the property previously leased by the Debtor is a priority ad- 3 ministrative expense." By a decision dated the same date, a copy 4 of which is attached to the Stipulation as Exhibit "D", the Dis- 5 trict Court also affirmed the Third Order. 6 8. Caskey has appealed from the orders of the District 7 Court described in paragraph 7, above. Those appeals are current- ~ ly pending in the united States Court of Appeals for the Ninth 9 Circuit as Case Nos. 89-15632 and 89-15635, and are hereinafter 10 referred· to collectively as the "Appeals." 11 Phoenix Trust has filed two proofs of administra- 9. 12 tive claim against the estate of B,C" copies of which are at- l) tached to the stipulation as Exhibits "E" and "F", respectively. 14 The first proof of claim asserts an administrative claim for any 15 costs of cleanup of the Premises I and estimates that the cost of 16 cleanup for which an administrative claim is asserted ranges from 17 $400,000 to $1.7 million. The second proof of claim asserts ad- 18 ministrative claims for monthly rent under the lease of the Pre- 19 mises, as'well as the aforesaid cleanup costs. These claims are . hereinafter referred to, collectively as the "Proofs of Claim." 10. Caskey and Movant each dispute the claims asserted 22 by Phoenix Trust. 23 11. Coskey asserts administrative claims against the 24 estate of B.C. for services rendered as counsel to the Creditors' 25 Committee in the superseded chapter 11 case and also for services 26 which it has rendered in litigating the matters described in Para- 27 graphs 4-8 above and related matters respecting the estate's a1- 28 leged responsibility for cleanup of the Premises. caskey has pre- '119l ion.Ptd -5- . , 113'1'91 Mocion.Ptd 1 viously been awarded the sum of $12,399.66 on account of fees and 2 costs as counsel for the Creditors' Committee. In addition, Cos- 3 key contends that its services in litigating matters respecting 4 the estate's alleged responsibility for cleanup of the Premises 5 have made a substantial contribution to the estate, and have con- 6 ferred upon the estate a substantial benefit. These claims are 8 7 subject to determination by the Court. 12. By entering into the stipulation, Movant, Phoenix 9 Trust, and Caskey desire to resolve their disputes regarding 10 (a) the amount and priority of the claims of Phoenix Trust; and 11 (b) the timing of the payments of those claims vis-a-vis other 12 administrative claims. It is Movant's view that among the more 13 salient provisions of the stipulation are the following: 14 15 16 17 18 19 20 21 22 23 24 25 26 27 III 28 III a. Following the entry of an order of this Court authorizing Movant to enter into the stipulation, and an or- der of the Kern County superior Court I proceeding No. 202010, authorizing Phoenix Trust to enter into the Stipulation, Mov- ant will pay $395,000 to phoenix Trust. b. Phoenix Trust will withdraw all of the Proofs of Claim. c. On or before the payment to Phoenix Trust of the $395,000 described above, Movant will pay to Coskey the amount of such administrative claim as the Court allows to coskey for fees and expenses not previously paid to Coskey. Movant anticipates that coskey will file an application for compensation and reimbursement of expenses which will be -6- 1 and will ensure that some distribution can be made to the 2 holders of nonpriority general I unsecured claims in this 4 3 case. 14. Based on the foregoing, Movant believes that the 5 stipulation is in the best interest of the estate and should be 6 approved. e: 9 DATED: 10 11 12 13 14 15 16 17 18 19 _0 21 22 23 24 25 26 27 28 ']'2'92 Itfon.Pld ..,.

Chemicals' Union Avenue Supply Yard to ascertain compliance with Waste Discharge Requirements (WOR) Order No. 80-129. I was accompanied by Mr. Ernie Phoenix, owner of the property; Mr. Bill Puette, legal counsel to Phoenix Trust; Ms. Margaret DeVine with Wells Fargo Bank; Mr. Tony Ramirez with Groundwater Resources, Inc.; and Mr. Adam Ng and Mr. Yoon Toh with ICf Kaiser Engineers. I did not observe any violations of the WORs during the inspection. B.C. Chemicals leased the property from Phoenix Trust from about 1972 to 1985. During that time, B.C. Chemicals manufactured solvent emulsion degreasers and formulated oil field chemicals such as acids and caustics. WDR Order No. 80-129 was adopted to regulate disposal of waste water generated from washdown of chemica 1 mixing faci 1 it ies and from spi llage. Apparent 1y, waste water had previously been discharged to an earthen drainage sump. A concrete-lined sump was later installed and the earthen drainage sump was covered over with soil. I was informed by Mr. Phoenix that no manufacturing or formulating has occurred at the site since B.C. Chemicals left in 1985. It appears that no wastewater has been discharged to the sump since B.C. Chemicals ceased operations at the site. The site is currently undergoing closure. During the inspection I observed the concrete-lined sump located adjacent to a warehouse. Between the warehouse and the sump was a curbed concrete pad that was sloped to drain to the sump. The sump was approximately 8 feet wide by 8 feet long and 2 feet deep. The sump was dry at the time of this inspection although it did appear to have some sediment in the bottom. L also observed the area where the earthen drainage sump is located. However, as this area has been filled in with soil, I was not possible to determine its precise location. I did not observe, any formu lat ing or manufacturing processes or any waste water discharges during this inspeëtion. .

CHEMICALS, KERN COUNTY DATE: I have reviewed a site characterization work plan that proposes soils and ground water assessment at a site previously operated by B.C. Chemicals. The work plan was prepared by Groundwater Resources, I nc. in response to comments ra i sed in our memorandum dated 29 January 1990. The work proposed in the work plan appears to be an appropriate step toward assessing soil contamination and potential ground water degradat i on at the site. There are, however, items in the work plan that will requ i re further information. My comments regarding the work plan are as follows. - The work plan proposes to place fifteen soil borings at known or suspected areas of soil contamination, including sumps, spills, leaks, and rinse water runoff. These borings will be advanced until two consecutive samples show no contamination. If ground water is encountered before the edge of the plume is found then the borings will be converted into monitoring wells. The work plan further proposes to analyze composite samples obtained from ten surface locations in the general yard area. A subsurface geophysical investigation will also be conducted to identify any buried drums, an alleged disposal well, and other buried utilities. The locations proposed for placement of the borings appear to be appropriate to provide an initial assessment of soils in the vicinity of known or suspected areas of soil contamination. However, depending on the results of this phase of the investigation, additional sampling may be required at a later date. Two borings are proposed to be placed to test soils in the vicinity of a concrete- lined disposal sump. However, the precise location of the proposed boring relative to the sump is not indicated in the work plan. Without this information I it is not possible to tell if the borings will be placed to determine the full extent of potential impacts from the sump. The work plan proposes to obtain 10 composite surface soil samples from the general yard area. These will consist of grab and hand augured samples obtained within the first foot below ground surface. The work plan, however, dÓes not provide information about how the samples will be composited. Misleading information can be obtained about the magnitude of surface soil contamination, depending on how the samples are compos;ted. The work plan proposes that the lateral on-site extent of any contamination plumes will be defined by installing more borings. There is no indication, however, that 1 Reviewed by:\t;ìL I'0J/qJ./f;1 I .J I I/J e e B.C. CHEMICALS KERN COUNTY -2- any off-site sampling will be performed. The full extent of contamination will need to be determined even if the plume has migrated off-site. The work plan indicates that all soil samples will be analyzed for non-halogenated volatile organics by EPA Method 8015. Compounds detected but not quantified by this method will be further analyzed by EPA Method 8270 (semi-volatile organics). The work plan further indicates that a modified Method 8120 will serve to collect the chlorinated compounds; however, it does not state which ór how many samples will be analyzed with this method. Available information indicates that a wide variety of chemicals have been inventoried at the site. It will be necessary to ensure that analyses are performed for all contaminants of concern, especially when determining the boundary of any contaminant plumes. Information in the file indicates that ketones have been used at the site, so Method 8015 appears to be appropriate to analyze for these compounds. However, Method 8015 may not detect all of the semivolatile compounds quantified by Method 8270. As such, Method 8015 may not be appropriate to detect for semivolatile organics. The proposal to obtain soil samples at five-foot intervals and at significant lithologic changes appears appropriate. The work plan indicates that field analyses of soil samples will be performed to make an initial determination of hydrocarbon concentrations. Selected samples are proposed to be held for further analyses by a state certified laboratory after examination of all field data. Care should be taken to ensure that the 14-day holding time in EPA SW-846 for Methods 8015 and 8270 are not exceeded. If a boring is advanced to ground water it will be subsequently converted to a monitoring well. The work plan indicates that we will be notified and the appropriate permits will be obtained, and construction will be, in compliance with the county guidelines. However, the work plan did not include construètion details, such as the screened interval length or a cross-section diagram of the proposed monitoring wells. This information will need to be provided for our review prior to installing any monitoring wells at the site. The work plan indicates that ground water samples may be pumped into sampling bottles. However, certain pumping methods may allow the volatilization of certain organic compounds in the sample, which could result in misleading information about ground water quality. The work plan provides a discussion of QA/QC procedures; however I certain procedures were not indicated. We will need to be provided with additional information regarding laboratory and field blanks, duplicate samples and spiked samples. We will also need information on background levels of any contaminants analyzed that also occur naturally in soils. , · e B.C. CHEMICALS KERN COUNTY -3- CONCLUSIONS The work proposed in the work plan appears to be an appropriate step to determine the extent of soil contamination and potential ground water degradation; however, there are questions regarding the following items, which need to be addressed: 1. The locations of borings 8-104 and B-I05 relative to the sump were not explicitly described. / 2. The method of compositing the surface soil samples was not described. 3. Off-site monitoring was not discussed. Off-site monitoring may be necessary in a subsequent phase of the assessment. 4. EPA Method 8015 is for analysis of nonhalogenated volatile organics and Method 8270 is for analysis of semivolatile organics. As such, Method 8015 does not appear to be appropriate to detect constituents quantified by Method 8270. 5. The work plan did not provide construction details of the monitoring wells, including screen length and cross section diagrams. 6. The work plan indicated that ground water samples may be pumped from monitoring wells. However, certain methods of pumping ground water samples may volatilize organic constituents, providing erroneous results. 7. The work plan did not provide sufficient QA/QC information regarding blanks, duplicates and spiked samples. 8. The work plan did not indicate that analyses would be performed for all constituents of concern, especially for determiojng the boundary of the contaminant plume. JOB 88037 FIGURE 4 u.s.

STATEMENT OF THE ISSUE -- -- BC Chemicals previously operated a facility located at 1511 South Union in Bakersfield, California. Closure of the facility resulted in approximately 2500 drums of materials and a variety of tanks left on-site. AS of this time, about 2400 drums have been removed. Questions which remain to be addressed include final disposition of the materials in drums and tanks, soil assessment, and potential groundwater assessment. This report specifically addresses soil assessment. Any potential groundwater assessment would be performed by Kenneth Schmidt and Associates. The geotechnical investigation would include determination of the soil profile, sampling and testing, and the lateral and vertical extent of soil contamination, assuming that the extent does not exceed moderate soil depths. The report would address potential remedial measures, assuming that the depth does not exceed moderate soil depths. FACILITY DESCRIPTION The BC Chemicals facility is located in a primarily industrial area of Bakersfield; residences however are nearby. The facility includes three buildings, which vary from wood floor to slab on grade to dock height fill. Approximately a dozen large storage tanks are present and a larger number of apparently temporary poly tanks are on site. TWO soil piles are present, as well as several rolloffs for solid waste disposal. At one time, the site contained about 2500 drums containing a wide variety of chemicals; previous cleanup operations have reduced the drums to about 100 in number. The storage tanks and poly tanks still contain materials. Current tanks and drums are identified by a numbering system; we do not have access to the code. potential soil contamination problem areas were observed in our visit of October, 1988. These include surface discoloration, low spots, and crusted salts. The location and configuration of the facility is shown on the site Plan, Figure 1. e - AT /JMM Page 1 - e " I SITE DESCRIPTION The site is essentially bare ground cover with a slight slope down to the west. The overall size of the site is about 2.5 acres. Immediately west of the site are the railroad tracks, which act to channel and dam runoff which would traverse the site. other manufacturing or commercial facilities lie north and south of the site. PREVIOUS WORK Previous work has been performed by Emcon and Associates. We do not have copies of all the work performed. We understand that the work included primarily drum classification and removal, as well as a work plan for further soil characterization. We have test results from the September 5, 1985 inspection performed by Kern County, the State Department of Health Services, and various other enforcement agencies.

The buried drum pit(s) is described as located in the rear of the yard with an approximate date of excavation of 1980 to 1981 or 1983. The excavation was about 20 feet deep. several hundred drums were reportedly buried. A number of people with potential knowledge regarding the pit(s) is listed. The disposal well is listed as unlined and 100 to 150 feet deep. Chemicals were reportedly dumped into the well. A number of people with potential knowledge regarding the well is listed. ITEM 2.

The soils range from clay to sand and contain some layers with gravel. Generally, a significant clay strata is shown within the top 30 feet of the soil profile. RATIONALE FOR DEPTH AND LOCATION OF TEST HOLES The depth of the test holes would be 30 feet, as the soil profile information indicates that significant clay strata are likely to be encountered at or before that depth. In the event that contaminated soils are indicated to proceed below 30 feet at the time of investigation, either on the basis of odor, discoloration, or significant registering on a HNU, the test holes would be deepened. e Page 5 e AT /JMM e e Test holes should be located at known or suspected locations of previously problematical tests, sumps, spills, leaks, concentrated runoff, discolored areas, general yard areas or other on-site waste disposal practices. previously Problematical Tests Three test holes have been located on the site plan, Figure 1, at the locations shown below. These are previous DOHS test results indicating problematical levels in the soils. One test hole was eliminated from the four locations as BAB 175 and BAB 176 are within 5 feet of each other at the surface. These test holes have been numbered TH-lOl to.TH-l03.

Sumps A total of two sumps were observed at the site. TWO test holes are proposed to depths of 30 feet at these locations. These are called TH-104 and TH-l05 on the Site Plan. Spills A total of eight spill locations were observed at the site. One of these locations is apparently the Foamer tank previously assigned a test hole. Several of these spills are of such close proximity that one test hole has been recommended to account for more than one spill. A total of 4 additional test holes to 30 feet are proposed at these locations. These are called TH-I06 to TH-l09 on the site Plan. Discolored Areas A total of three discolored areas, over and above the spills previously noted, were observed at the site. Three test holes to 30 feet are proposed at these locations. They are called TH-IlO to TH-l12 on the Site plan. Leaks The current program of testing spills and discolored areas accounts for all leaks which we have knowledge of. Therefore, no additional test holes have been specifically assigned to leaks. e e AT ~MM page 6 e - BC Chemicals Bakersfield, California JOB 88037 October, 1988 ITEMIZED BREAKDOWN: GEOTECHNICAL INVESTIGATION 1.

Three areas are specifically proposed for drilling, shown on the site plan as TH-113 to TH-115. The test holes would be drilled to 30 feet. General yard Areas Ten samples would be taken of surface soils in the general yard area. These samples would consist of composite" samples of the top one foot at each location. On-site Disposal practices Investigative reports of on-site disposal practices have indicated pit(s) for burial of several hundred drums and an on-site well. The location of the pit(s) is not known, except that it was near the rear of the facility. The depth is expected to be 20 feet. The time frame is expected to be 1980 to 1983. We would expect that the references given would be contacted to determine the likely location of the pit(s). In the event that the location of the pit(s) cannot be established through contact of the references given, aerial photographs of that time frame would be obtained. . In the event that the location of the pit(s) is determined, test holes would be drilled to depths of at least 30 feet at those locations. Because the location is unknown, the test holes are not shown on the site Plan. In the event that no pit is found on the aerial photos, three probes would be drilled in the rear yard areas at locations compatible with such an excavation. The location of the well is not known. The depth is expected to be 100 to 150 feet. The time frame is unknown. We would expect that the references given would be contacted to determine the likely location of the well. In the event that the location of the well cannot be established through contact of the references given, County well records would be researched. In the event that the location of the well is determined, the well would be uncovered and a sample from inside the well obtained. Because of the extreme depth of the well and the proximity of the bottom of the well to the groundwater table, any further evaluation would be part of a groundwater investigation. Because the location is unknown, the sampling is not shown on the site plan. In the event that no well is found from either investigative reports or research of County records, no further work could be performed. e e AT ~MM Page 7 e e RATIONALE FOR TESTING SCHEDULE Data already exists with regard to the chemicals present in the soil profile. The data indicates that the principal problems are pH and semi-volatile organics. The testing schedule would emphasize these types of tests, with occasional testing for volatile organics and selected metals. Initially, virtually all samples would be tested by EPA 8015, which is a total hydrocarbon determinant. Semi-quantified compounds detected on the EPA 8270 would be detected on the 8015, though not identified. Those samples which showed significant amounts by the 8015 would be retested by the 8270 to distinguish the specific compound. For estimating purposes, it has been assumed that 10 EPA 8270 tests would be required. The samples would be tested, at least initially, at the ground surface, at a depth of five feet, and in the anticipated clay layer near 30 feet. The other soil samples would be held until the initial test results were available. The rationale behind the three samples per hole being tested is that there are generally three concerns in an area of surface infiltration. First, there is concern on whether the site is a near surface disposal source, which would be addressed by the shallow sample. Second, if there is significant contamination in the near surface, there is concern whether this is attenuation occurring with movement towards the groundwater table. This is addressed primarily by the midpoint sample and to a lesser extent by the deeper sample. Third, there is the potential that the clay strata may serve as a confining layer for any further penetration of contaminants. Testing would also be performed to assess general permeability characteristics. This would be correlated with soil type and stratification to assist in evaluating whether restrictive strata were present above the groundwater table. The following testing schedule is proposed. e e AT ~MM Page 8 e e TH-IOI TH-I02 TH-I03 TH-I04 0.0' pH/BOIS/B020 pH/BOIS/BOlO pH/BOIS/B020 pH/BOIS/BOlO 2.0' Barium, Lead Hold Hold Hold 5.0' pH/BOIS/BOlO pH/BOIS/B020 pH/BOIS/BOlO pH/BOIS/B020 7.5' Hold Hold Hold Hold 10.0' Hold Hold Hold Hold 15.0' Hold Hold Hold Hold 20.0' Hold Hold Hold Hold 25.0' pH/BOIS/B020 pH/BOIS/BOlO pH/BOIS/S020 pH/SOlS/BOlO 30.0' Hold perm Hold Hold TH-IOS TH-I06 TH-I07 TH-IOS 0.0' pH/BOIS/SOlO pH/SOIS/B020 pH/SOlS/BOlO pH/SOIS/B020 2~0' Hold Barium, Lead Hold Hold 5.0' pH/BOIS/B020 pH/BOIS/BOlO pH/SOIS/S020 pH/SOlS/SOlO 7.5' Hold Hold Hold Hold 10.0' Hold Hold Hold Hold 15.0' Hold Hold Hold Hold 20.0' Hold Hold Hold Hold 25.0' pH/SOlS/SOlO pH/SOIS/S020 pH/SOlS/SOlO pH/SOIS/S020 30.0' Hold Hold Perm Hold TH-I09 TH -11 0 TH -111 TH -112 0.0' pH/SOlS/SOlO pH/SOIS/S020 pH/SOlS/SOlO pH/SOIS/B020 2.0' Hold Hold Barium, Lead Hold 5.0' pH/SOIS/S020 pH/SOlS/SOlO pH/SOIS/S020 pH/SOlS/SOlO 7.5' Hold Hold Hold Hold 10.0' Hold Hold Hold Hold 15.0' Hold Hold Hold Hold 20.0' Hold Hold Hold Hold 25.0' pH/SOlS/SOlO pH/SOIS/S020 pH/BOIS/BOlO pH/BOIS/B020 30.0' perm Hold Hold Hold Page 9 e e AT /JMM e e TH-113 TH -114 TH-11 5 0.0' pH/801S/8020 pH/801S/8010 pH/801S/8020 2.0' Hold Hold Barium, Lead 5.0' pH/801S/8010 pH/801S/8020 pH/80lS/8010 7.5' Hold Hold Hold 10.0' Hold Hold· Hold 15.0' Hold Hold Hold 20.0' Hold Hold Hold 25.0' pH/801S/8020 pH/801S/8010 pH/801S/8020 30.0' Hold Perm Hold Depth 5-1 5-2 5-3 5-4 S-S S-6 s-7 S-8 5-9 5-10 0'-1' 8020 8015 8010 8020 8015 8010 8020 8015 8010 8020 pH pH pH pH pH pH pH pH pH pH Barium Lead Barium Lead Lead At the conclusion of initial testing, substitute ten additional 8270 for 8015 which show significant concentrations. ITEM 3. SOIL S&~PLING, STORAGE AND PRESERVATION -- SOIL SAMPLING Test holes would be drilled from a truck mounted drilling unit by a California licensed (C-57) drilling contractor. Drilling would be performed with hollow stem augers. Because of the potential for cross contamination between test hole locations, the equipment would be steam cleaned between drilling locations. During the drilling operations, soil samples would be taken every 2.5 feet down to 10 feet and on 5 foot intervals thereafter. The samples for chemical testing would be taken with a 1.75 inch inner diameter, 2.00 inch outer diameter, split barrel sampler with stainless steel liner tubes. The sampler is advanced into the soils by hydraulically pushing or by driving with a 140 pound hammer and a thirty inch drop. The sampler would be washed between sampling intervals. The drilling and sampling would be performed under the supervision of John Minney, Consulting Engineer. e e AT /JMM Page 10 e e TEST HOLE BACKFILL After completion of drilling, the test holes would be filled with concrete. SAMPLE STORAGE AND PRESERVATION While on-site or in transit, the samples are stored in cool storage containers to maintain temperature and volatile organic concentration. Storage containers have blue ice. The samples would be returned to APPL Labs in Fresno in a similar condition. ITEM 4. SOIL PHYSICAL PROPERTY TESTING --- Soil physical property testing would include moisture content, dry density, liquid and plastic limit, and permeability. MOISTURE AND DRY DENSITY Moisture content would be determined in general accordance with ASTM D 2216. Tube samples were nominally 2.5 inches in diameter and 6 inches long. Both ends of the tube were trimmed for insertion into the permeability test apparatus. The moisture content determination was made on the material trimmed from the ends of the tubes. Dry density was determined on the basis of the soil in the sampling tube after trimming of the moisture content sample. PLASTICITY INDEX The plasticity index would be determined in accordance with ASTM D 423 and ASTM D 424. PERMEABILITY The permeability testing of the soil samples would be performed in accordance with methods suggested by Subchapter 15. The key parameters which are to be e e AT /JMM Page 11 e e accounted for in the test procedure include the undisturbed soil sample characteristics, the pore fluid and the gradient. The soil samples would be undisturbed specimens from depths of 5 to 20 feet below site grade. In this area, soils are considered as sUbstantially preconsolidated. This means that the soil specimens would contain important structural features related to the age since deposition. The test method should be designed to minimize the sample disturbance in order to retain the important structural features. Test methods which utilize remolded soil specimens, such as would be used for primary liners, were considered inappropriate. The pore fluid which the soil strata may ultimately be subjected to may entail a fluid either composed of relatively clean water, a concentrated solvent solution, or an intermediate mixture. The relatively clean water could represent some form of natural infiltration, such as perched water developing in times of relatively wet weather. AS Subchapter 15 assumes that the soils are presaturated with clean water, a small amount of clean water was used to initially saturate the soil specimens. The actual test would be performed with a dilute concentration of volatile organics. The test gradient and total pore fluid replacement during the test are variables which are interdependent. The gradient refers to the head loss of the pore fluid during the flow through the soil specimen. The higher the test gradient, the higher the flow through the sample. However, fine grained soils often exhibit threshold gradients, below which flow does not occur. Running the test procedure at a gradient well in excess of the gradients to be expected in the field may result in erroneously high values of permeability. Field gradients would be expected to be on the order of one, and certainly no more than ten. A test gradient of six would therefore be used as a realistic and somewhat conservative number. The total pore fluid replacement rerers to the amount of permeant actually pushed through the sample in relation to the amount of water initially in the sample. As the pore fluid moves into the soil specimen, the permeability of the specimen may be modified by interaction with a pore fluid which contains various constituents. The more the pore fluid is replaced with the test fluid, the more the permeability represents the true value in the field. Subchapter 15 indicates that unattenuated test fluid exits the sample when approximately 50 percent of the pore volume is replaced. e e AT /JMM page 12 e e The specific test method used would be the constant head method. subchapter 15 allows for testing of clay soils by either the constant head or falling head method, without stating a preference for either. The constant head method was selected as it allows for a more direct interpretation of the stabilization of test results. In the test procedure itself, constant flow occurs with constant head at the point where stabilization has occurred between the sample and the pore fluid. ITEM 5. CHEMICAL ANALYTICAL METHODS -- CONTAMINANTS OF CONCERN The contaminants of concern are those indicated by the previous testing program, including pH, total hydrocarbons, semi-volatile organics, acid and base neutral extractables, barium, lead, plus additional volatile organics. TEST METHODS AND DETECTION LEVELS All chemical testing would be performed by aSK and Associates of Fresno, california. BSK and Associates is certified by the State of California Department. of Health Services for the test methods outlined in this program. In testing for water or soil contamination, there are several important concepts that should be understood in order to discuss the data. These concepts include background levels, degradation, action levels, detection levels and interference. Background levels are considered to be the levels present without the influence of the project in question. Usually, the background levels are those levels which are naturally occurring. In some instances, the prior usage of the site or usage of surrounding sites may result in background levels which are not naturally occurring. To a certain extent, all general mineral constituents and metals are naturally occurring. The semi-volatile, acid and base neutral extractable and volatile organics are not typically naturally occurring but frequently come from other industrial sites. e e AT /JMM page 13 e - Degradation occurs where the level of a constituent in the soil or water, in an area influenced by the project, exceeds the background level. There are statistical procedures for determing whether the difference is statistically significant; however, the procedures are questionable because of the preponderance of false positives generated by the procedures. State regulations generally do not allow degradation. Action levels are levels set by the governing agency which may not be exceeded. They are typically set for drinking water, although other levels are set for other purposes (e.g. to distinguish hazardous waste from designated waste). Although state regulations do not allow degradation, it is usually the action levels which are enforced. Detection levels are those minimum levels which are measured in the laboratory test. Laboratory tests are to be selected such that, for items which have a defined action level, the detection level is less than or equal to the action level. The nominal detection levels are levels which may be obtained under relatively ideal laboratory conditions, particularly samples which have no interference. Interference occurs when the level of other materials in the soil or water is so high as to mask the presence of the contaminant of concern. All priority pollutant scans under our direction would be performed in accordance with the test methods recommended by the U. S. Environmental Protection Agency. The soil samples would be tested in accordance with EPA 8010, 8015, 8020 and 8270. If unusual interference effects are present in the test specimens, individual detection limits are increased. In previous tests at this site, substantial interference was recorded. Chemical tests on water samples for purgeable halocarbons would be conducted in accordance with EPA test method 8010. The halocarbons are efficiently transferred to the vapor phase by a headspace extraction. The vapor is swept through a sorbent trap where the halocarbons are trapped. After purging is completed, the trap is heated and back flushed with the inert gas to desorb the halocarbons onto a gas chromatographic column. The gas chromatograph is temperature programmed to separate the halocarbons which are then detected with a halide specific detector. All test results are confirmed by use of a second chromatographic column. The basic 8010 scan includes 29 constitituents, although more may be included. The constituents measured by the 8010 method are typically not naturally occurring groundwater constituents. Eight of the 29 basic constituents have state action levels for drinking water, which vary from 0.1 ppb to 200 ppb. Typical detection limits in soil would be 0.1 ppm. Page 14 e e AT ~MM e e Chemical tests on soil samples for purgeable aromatics would be conducted in accordance with EPA test method 8020. The aromatics are efficiently transferred from the aqueous phase to the vapor phase by a headspace extraction. The vapor is swept through a sorbent trap where the aromatics are trapped. After purging is completed, the trap is heated and backflushed with the inert gas to desorb the aromatics onto a gas chromatographic column. The gas chromatograph is temperature programmed to separate the aromatics which are then detected with a photo ionization detector. The basic 8020 scan includes 7 consitituents, although more may be included. The constituents measured by the 8020 method are typically not naturally occurring groundwater constituents,. Five of the seven basic constituents have state action levels for drinking water, which vary from 0.7 ppb to 620 ppb. Typical detection limits in soil would be 0.1 ppm. Chemical tests for total extractable hydrocarbons would be performed by the infrared spectroscopy method delineated in EPA 8015. A soil sample is extracted with hexane, treated to remove non-petroleum oils and greases and then quantified by scanning infrared spectroscopy. Chemical tests on water samples for Base/Neutrals and Acid Extractables would be performed in accordance with EPA test method 8270. A measured volume of sample, approximately one liter, is serially extracted with methylene chloride at a pH greater than 11 and again at a pH less than 2 using a separatory funnel or a continuous extractor. The methylene chloride extract is dried and concentrated to a volume of lmL. Chromatographic conditions are described which permit the separation and measurement of the parameters in the extract. Qualitative identification is performed using the retention time and the relative abundance of three characteristic ions. Quantitative analysis is performed using either external or internal standard techniques with a single characteristic ion. The basic 8270 scan includes 81 constituents, although more may be included. The constituents are typically not naturally occurring groundwater constituents. Eight of the 81 constituents have state action levels for drinking water, which vary from 20 arts per trillion (ppt) to 30 ppb. Typical detection limits in soil would be 0.1 ppm.

REPORT OF FINDINGS -- DATA The data included in the report would consist of the following items: previous Chemical Test Results Test Hole Logs Moisture, Dry Density, Plasticity Index and permeability Determinations Results of Chemical Tests on Soil Samples as Outlined in Testing Schedule DOCUMENTATION The documentation would include a description of the methods, standardized where applicable, used in developing the data in the previous report sections. CONCLUSIONS Our report would contain conclusions regarding the soil profile, the presence of soil contamination, and the lateral and vertical extent of soil contamination. This is based upon the assumption that the lateral and vertical extent did not greatly exceed the dimensions of the site or a depth of 30 feet. The issue of groundwater contamination would be addressed by Ken Schmidt, consulting Geologist. The potential impact of chemical concentrations in the soil on groundwater would be addressed. This would include the potential for downward movement through leaching, as well as effects of rise in the groundwater table. The surface concentrations would be compared to known hazardous values where applicable. Our report would recommend the type of remedial actions, if any, that might be required, including on-site stabilization, recycling, on-site treatment and off-site disposal. page 16 e e AT /JMM e e LIMITATIONS The analyses and recommendations contained in the report would be based upon the data obtained from the test holes installed at the locations shown on the Site plan in Figure 1. The report would not reflect variations which may occur between borings. The nature and extent of such variations may not become evident until more detailed studies are performed. If variations then appear, a re-evaluation of the recommendations of this report would be necessary after additional studies. The Geotechnical Engineer would prepare this report for the exclusive use of the Owner. The report would be prepared in accordance with generally accepted geotechnical engineering practices. No other warranties, either expressed or implied, would be made as to the professional advice provided under the terms of this agreement and included in this report. ITEM 7. SCHEDULES -- The field operations would commence within four weeks of notification to proceed. We expect to complete the field work within one week. Laboratory .testing would include an additional six weeks. Report preparation would take an additional four weeks. We expect to submit a finished report within fifteen weeks of notification to proceed. ITEM 8. PROJECT STAFF -- - The project manager will be Mr. ~ Minney. Mr. Minney is a Licensed Civil Engineer (NO. CE 32537), Geotechnical Engineer (No. 602) and Registered Environmental Assessor ( No. 00212) in the state of California. Mr. Minney has considerable experience in investigations for chemical contamination of soil and ground water, with projects ranging from municipal sewage to solid waste disposal facilities to underground tank leaks to hazardous waste disposal sites. page 17 e e AT /JMM e e FIELD TESTING AND SAMPLING The field testing and sampling would be performed by John Minney, Consulting Engineer. Page 18 e e AT /JMM e e QUALITY CONTROL Page 19 e e· BSI( - .. - . -- & ¡\,,«'ci,ltl" e e QUALITY CONTROL Laboratory Quality Control is an essential element of any laboratory Quality Assurance Program for obtaining prescribed standards of performance in the monitoring of the measurement process. The main objective is to provide a uniform basis for sample collection and handling, instrument and method maintenance, performance evaluation, and analytical data gathering and reporting. Control and establish the tracability of standards, instrumentation, samples and environmental data. Demonstrate the validation of data each time they are recorded, calculated or transcribed. Record keeping is our essential part of any quality control system. Data handling, reporting of data and record keeping serve two, useful functions: a) It enables us to re-analyze a set of data at a futu~e date. b) Can be used in support of experimental data of the dates called into question The following are procedures which BSK will utilize to insure good quality control. If the QC requirements for a particular method are more stringent than those described below, the method criteria will be used. At a minimum, blanks, duplicates and spikes will be analyzed once for every batch of samples or type of matrix or 20 samples whichever is more frequent. Analysis of Blanks 1. A method blank is a volume of 01, purified soil, solvent or other matrix that is carried through the entire analytical scheme. 2. The method blank is used to monitor background levels of contamination from glassware, reagents or laboratory environment. It is advisable to prepare two method blanks. Inorganic determination - if concentration of analytes in the method blank are less or equal to the MOL for that element, no correction of the sample is performed. Otherwise, the least concentrated analyte in a sample must be lOX the blank concentration, or all samples associated with the blank with less than lOX the blank concentration must be re-prepared and re-analyzed. b. Organic analyses - compounds in the method blank must not exceed 5X the MOL for that compound. This pertains only to common iabGratory solvents such as Methylene Chloride, Chl~~oform and Acetone. No discernable peaks should be present. BSI( 3. X"~()-íi;ltl:~ 3a. v e Page 2.0 e e e 4. Travel Blanks or Field Blanks received with samples are treated and analyzed as a sample only if a problem is discovered, the ana1yte being tested for is present or analysis of these blanks is requested by the customer. 5. Travel Controls are prepared by BSK samplers in the lab and transported to the field and handled as samples, e.g. same ice chest, with the sampler at time of sampl ing. The travel control will be exposed to the same environmental factors as the samples. It is not the policy of BSK to analyze these controls unless a problem is discovered or the analyte being tested for is present. Analysis of Spiked Samples 1. At least one spike sample analysis must be performed on each group of samples of a similar matrix type (i.e., water, soil) and concentration (i .e., 10',0/, medium level) whichever is more frequent. A sample is chosen at random to spike. Two equal aliquots of the same sample are prepared independently for analysis and one of the samples spiked with a known amount of the analyte, or, in the case of organic analyses, having the same or similar characteristics as the analyte being tested for. 2. By the addition of compounds or elements with known concentrations to samples, accuracy can be checked in terms of percent recovery. Percent recovery is the increased value for a sample spike resulting from the addition of a known amount of analyte compared to the same sample with no spike added. 3. Some organic methods require the addition of surrogate spikes to all samples, blanks and standards. 4. Percent recovery criteria are as follows unless otherwise specified by a particular method or contract requirements. a. Inorganic recover'ies - the warning limit is defined as the mean ± 2X the standard deviation of the recoveries of 20 analyses per element. The out of control limit is the mean ± 3X the standard deviation of recoveries for the same 20 analyses. Anything over ± 3X is considered unacceptable and BSI( g. "\.;.;oci,!t.,.; e Page 21 e e e may require re-analysis of all samples associated with the spike. (See Data Quality Assessment and Reporting). b. Organic recoveries - the range of recovery for each compound is the mean recovery ± 2X the standard deviation of the recoveries of 10 analyses. Anything over ± 2X the mean is unacceptable and may require re-analysis of all samples associated with the spike. (See Data Quality Assessment and Reporting). Analysis of Duplicates 1. A duplicate sample is analyzed for each group of samples of a similar matrix type (i.e., water, soil) and concentration (i.e., low, medium level) whichever is more frequent. Through the analysis of duplicate samples, the lab can assess the precision of sampling, preparation and analytical techniques. When feasible,the use of matrix spike duplicates are required which would entail three equal aliquots of the same sample being prepared independently for analysis and two of the sub-samples being spiked with exactly the same concentration of solution. 2. If it is not feasible to utilize matrix spike duplicates, due to the nature of the method, a sample is chosen at random and two equal aliquots are prepared i~dependently for analysis. 3. To determine wh~ther a problem, when encountered, is due to sample preparation or 1S instrumental in nature, re-analysis of the duplicate samples would be indicated. 4. Acceptance criteria for duplicate analysis is as follows unless otherwise specified by a particular method or contract. a. Inorganics determinations - precision data will be stated in terms of Relative Percent Deviation (RPD). All elements should be less than or equal to 20% RPD. b. Organic analyses - precision data will be stated in terms of Percent Difference. Stable compounds should be less than or equal to 10% difference. The control limits for unstable compounds are determined by the mean ± 2X the standard deviation of the Percent Difference of 10 analyses. BSI( ~"' .,\ ~~0(~i~ 1~;'~ e Page 22 e e e Internal Standards Internal standards data are used to determine when changes in internal standard responses will adversely affect quantiation of target compounds with respect to internal standard area and retention time of internal standard. If the internal standard area is outside the upper or lower limits calculated, this information must be included with final data. For each internal standard, calculate the upper limit as the area of the particular standard plus 100% of its area (i.e., two times the area) and the lower limit as the area of the internal standard minus 50% of its area (i.e., one-half the area). Surrogate Recovery Surrogate standards are used in order to monitor preparation and analysis of samples, matrix spikes and blanks. If surrogate spike recoveries are outside QC acceptable limits, the problem must be considered analytical and measures taken to correct this matter. Measurement of Method Detection Limits 1. The laboratory will periodically reevaluate its method detection limits (MOL) for each matrix type and for each method. 2. The method used for calculating MOL is a prescribed by EPA, and is defined as the minimum concentration of a substance that can be identified, measured and reported with 99% confidence that the analyte concentration is greater than zero and determined from analysis of a sample in a given matrix containing analyte. a. Procedure 1. If the MOL is to be determined in water, prepare a laboratory standard of the analyte in reagent water at a concentration in the range of the estimated MOL - 1 - 5 times the estimated MOL is recommended. 2. For other matricies, it is best if the measured analyte is not greater than five times the estimated MOL. Ten times may be used but may not truly reflect method variance at lower levels of analyte concentrations. e Page 2} e BSI( & .\ .;-;nci,lte.; e e 3. Take seven aliquots of the above standards and process each through the analytical method and compute the results in the method reporting units - this must be done for the analyte in water, also if determining MOL for matrices other than water - obtain separate reagent blank measurements for each sample aliquot analyzed- the average blank measurement is subtracted from the respective sample measurements. 4. T6 calculate the MOL - find the standard deviation of the results for all seven analyses and multiply the standard deviation by the factor 3.143. Instrument Calibration 1. The following procedures will be followed to calibrate all instruments unless otherwise specified by the method or contract. a. Inorganic analyses - three standards of different concentrations will be analyzed (e.g.; .1, 1, 10) and linearity checked in terms of correlation coefficient and must meet a .995 linearity criteria. If this criteria is not met, troubleshooting will be necessary to determine the problem, and linearity for the standards must be established before analyses may begin. Calibration curves are used to illustrate linearity. For those compounds consistently not showing linearity over the three concentration range, calibration curves must be used. 1. A medium range standard will be analyzed at a frequency of 5% of all samples and must be with 10% of its initial calibration value. 2. To insure calibration accuracy a known EPA check sample or the equivalent, must be analyzed with every run. Results must be obtained within the EPA stated acceptable range or the calibration is not valid and re-calibration will be necessary. b. Organic analyses - three calibration standards will be analyzed. One of the standards should be near, but above the method detection limit for that compound. The other concentrations should BSI( & :\, -;()Cidlt·, - Page 24 e e e correspond to the range of the expected values of the samples or should define the working range of the detector or instrument. Response factors (RF = Instrument Response/Concentration of Analyte) will be determined and averaged for the three standards used in calibration for those compounds that show linearity of 10% or less Relative Standard Deviation (RSD) of the RFs' over the concentration range. For those compounds consistently not showing linearity over the three concentration range, calibration curves must be used. 1. Calibration of the instrument will be verified at the beginning and during every run at a frequency of 5% of all samples by running a mid-range check standard. If the response of this mid-range check standard is not within ± 10% of the average response factor a new average response factor will be determined from a three point recalibration. 2. To insure calibration accuracy, an EPA check sample, or the equivalent, should be analyzed occasionally, but not necessarily at a frequency of 10%. Results must be in the EPA stated acceptable range. Data Quality Assessment and Reporting (Precision and Accuracy) The review and reporting of analytical data is the concluding step in quality control procedures within the analytical laboratory. 1. The establishment of an acceptable range for accuracy and precision in the analyses of samples, method . blanks, spikes, duplicates and reference materials is an ongoing activity. This range is established for each analysis conducted by aSK, taking into consideration any contract requirements which may be applicable. 2. The steps to determine acceptability are as follows: a. evaluate the data for method blanks, spikes, duplicates, internal standards and surrogate recovery. b. recheck all calculations for accuracy. c. review all benchsheet data. BSI( . . +.0··· . & .'\';';OÜ,th - Page 2.5 e e e d. review instrument calibration data 3. If all data fall within the range, all calculations have been verified for accuracy and all instrumental calibration curve response data are within the acceptable range, .then data is accepted as valid. I 4. In the event that QC does not fall in range, corrective actions must be taken. a. If check standard is not in range ± 10% re-run new check std. If still not in range run new calibration curve and re-analyze samples. b. If EPA check sämple is not in range prepare new check sample. If error persists check standard preparation and re-calibrate instruments. Re-analyze samples. c. If duplicate is out of control, re-run ne\'/ duplicate set insuring homogeneity of sample. If homogenous sample is still out of range, examine digestion/extraction process for variables. Re-analyze sample group. d. If matrix spike is out of control, prepare new matrix spike. If problem persists, and standards, check samples and duplicates are in control, then chemical interferences are suspect. Use approved alternate method. If no approved alternate method exists, or is effective, results are to be reported with notation of the problem on the report. 5. All analytical and quality control results are reviewed and approved by the section supervisor and signed by them. Calculations 1. % Difference = value #1 - value #2 value #1 x lOa 2.

Laboratory Notebooks Each analyst maintains his or her own laboratory notebook which is used to record data and perform calculations for those analyses where worksheets are not provided. The laboratory notebook is also used to document peripheral information not directly required on a worksheet. 3. Graphs and Charts Each analyst is responsible for plotting and filing analytical standard curves. Graphs and charts which are produced as part of a final report are filed with the report. Chemists/Analysts are responsible for maintaining and updating quality control forms for their assigned analyses. These control forms are reviewed and then filed in a central location. 4. Inventory Control Logs Records are maintained on the purchase of laboratory supplies, detai1in~ the vendor, purchase order number, date of order, and date of receipt. Consumable supply forms are also maintained for mosts analyses to ensure adequate stock inventory and uniformity of supplies. Bottles of reagents are dated as soon as they are received so that the shelf life can be monitored. 5. Stock Standard Logs A log entry is maintained for each analytical stock standard. Each entry contains the date of fresh stock preparation and the results of the comparison between the old and new stocks as outlined in Section VI of this Quality Assurance Document. 6. Reagent Standardization Logs Log entries are maintained for standardized reagents which are not prepared fresh for each run but are instead periodically restandardized. Restandardization is customarily performed once a month and the new standardization factor recorded in the log along with the date and the analyst's initials. More frequent standardization may be required for certain reagents if a consistent quality control problem occurs. Page 29 e BSI( - $, :\,,(\( i.:t'." e e 7. Media Log and Prepared Media Log A media log is kept separately from the general inventory log. Upon receipt of new media, the date, the type of media, source of media, and initials of the individual receiving the media are logged into the media log. Media supplies are dated not only upon receipt but also when initially opened. A written record of quality control of media, materials, and equipment is logged into the Media Log Book. The record includes the results of the check, the initials of the individual performing the check, and the date. Media prepared in the lab is logged into the Prepared Media Log by the laboratory analyst. These records include media lot number, date, sterilization time and temperature, final pH, and the analyst1s initials. 8. Instrument Logs The operating temperatures of incubators, waterbaths, hot air ovens, and refrigerators are checked daily and logged in the maintenance log book. Adjustments are made when necessary. Autoclave temperatures and pressures are logged in the maintenance log book for each cycle of use. A separate log book is maintained for each analytical instrument. This log contains a record of daily instrument checks which are performed to verify proper functioning of instrument mechanics and to check performance on standards and reagent blanks. The log also contains.a record of the dates when routine instrument maintenance is performed, a description of any problems found, and the analyst's initials. If the instrument is not performing according to specifications, the appropriate instrumentation specialist must be called in to perform the necessary repairs.

Preliminary Cleaning All glassware is initially washed in a laboratory washer with distilled rinse capability. This glassware should be acceptable for use in analysis of most inorganic constituents in the mg/L concentration range. The surface of adequately cleaned glassware will drain in a uniform thin film. The formation of droplets upon drying is an indication that the glassware is not clean and must be rewashed. Most calibrated glassware such as pipes and graduates should be completely dry and cooled to room temperature before they are put away. Vo1umetrics are triple rinsed and then filled with deionized water before being put away to maintain the glass in a leached condition. 2. Low Level Phosphorous Glassware to be used for low level phosphorous determinations is soaked in 6N HCL to remove any phosphate detergent residue and rinsed several times with distilled water. A separate stock of glassware is maintained which is not washed with the regular glassware. 3. Organic Constituents Glassware. to be used for determination of organic constituents must be baked at 350°C for at least 8 hours in order to remove any remaining organic residue. 4. Trace metals Glassware to be used for trace metal analyses must be soaked overnight in 4N HN03 followed by 4-5 deionized water rinses. This glassware is stored separately from the regular glassware and should on1y.be handled with polyethylene gloves. 5. Grease Glassware to be used in determination of oil and grease or any glassware contaminated with grease is soaked in acetone or warm sodium hydroxide followed by an acid rinse and then washed in the usual manner. 6. Bacteriological Glassware to be used in bacteriological analysis is rinsed at least three times with distilled water which has not come in contact with copper tubing or other toxic material (pvc or BSI( e Page 32 - 1\ :\~q;Ci.lt(', e e stainless steel plumbing is acceptable}. All bacteriological glassware must be sterilized with some type of sterilization indicator prior to use. Analyses for toxic or inhibitory residues are performed on a routine basis. 7. Reagent Purity1 All solvents, reagents and gases used by BSK are of a consistent analytical quality and known purity. Purity is continually monitored by the analysis of method blanks with each project. All organic solvents are pesticide grade or equivalent. All other reagents are reagent grade, ACS or equivalent. Gases are USP or UPC grade. Materials which are subject to chemical change on prolonged exposure to ambient air: i.e. oxidation, absorption or loss of water, are never used as quantitive reagents without assay or standardization. If deterioration appears significant or there is reason to believe the material has been contaminated, it is immediately disposed of in a proper manner. 8. Holding Times The maximum allowable holding periods for stock standards, working standards and reagents for each analytical procedure are specified in the method writeups for those procedures. General guidelines for holding periods for stock standards are listed below: 1} Metal Stocks 10 ppm - 6 months 1-10 ppm - 60 days 1.0 ppm - fresh . 2} Anions, Nutrients, Cyanide, Phenol, COD Stocks 100 ppm - 60 days until longer holding times are demonstrated 100 ppm - fresh 3} Organics Stock standards are made up 4 times per year and stored in a freezer in the dark. ( 1 ) Please See Appendix liB II for sources of Standard Reagents e Page 33 - BSI( & ,\~,()('i.1t!'" e e 9. Verification of Standards Stock standards have specified holding periods. When a new stock standard is prepared, it must be cross-checked against the old one before it can be used. The old stock standard and a new stock standard of the same concentration are analyzed in triplicate. If the difference between the means of these triplicates is greater than 10 percent, another stock standard is prepared and these three standards are compared. If the old stock standard is suspect, the freshly prepared standard is compared against a known quality assurance sample such as those provided free of charge by EPA. Standards are labeled with the date, concentration, and preparer's initials. Preservatives or special storage procedures which are required to maintain the integrity of a standard are specified in the method writeup for that procedure.

Environmental Protection Agency 215 Fremont Street San Francisco~ California 94105 -,/"' ATTENTION: Mr. Enrique Manzanilla RE: Casa Loma Specific Plan and Final Enterprise Zone Application Draft Environmental Impact Statement SCH No. 85051304 Dear Ms. Ayres: The County of Kern Community Development Program Department has received and reviewed your comments dated October 27, 1986 regarding the Casa Loma Specific Plan and Final Enterprise Zone Application Draft Environmental Impact Statement (DEIS). Encloserr are our responses to your comments. A major concern with the DE IS is the proposed project's impacts to air quality in Kern County. After review of the Air Qualitv Analysis section of the DEIS by our staff and the consultants who prepared the DEIS~ it was learned that gross errors in projection figures had been made. The consultants have revised the air quality data and included all assumptions used in their analysis in a "Revised Air Quality Analysis" forwarded to EPA on November 5, 1986~ for review by EPA~ Air Management Division staff. It is our contention that in light of the revised data much of the concern over air quality impacts no longer applies. The omission of the presence of hazardous substances at the Bakersfield Airpark is primarily due to the fact that the situation was not known by us or the consultant during the preparation of the environmental document prior to its adoption as a Final Environmental Impact Report on January 15, 1985. In reference to the Garriott Crop Dusting facility at 2010 South Union Avenue, Garriott Crop Dusting contracted with a consultant who has submitted their report to the State Department of Health Services (DOHS) for evaluation. The Central Vallev Regional Water Quality Control Board required the City of Bakersfield prepare a e e Ms. Judith E. Ayres Page 2 February 23, 1987 report to characterize the extent of the contamination at the Bakersfield Airpark. The completed report was submitted to the Board on January 15~ 1987. The extent of contamination at the B. C. Chemical property located at 1511 South Union Avenue will be known when a site investigation is completed. Responsibility for cleanup of the site currently rests on B~ C. Chemical. The County of Kern has assumed lead agency status and will monitor the pr'ogress of B. C. Chemical's efforts for cleanup. This department, in cooperation with other local government entities and consultants, is prepared to address all issues raised by EPA and proposes to proceed with the preparation of the final DEIS. We look forward to scheduling a meeting with EPA staff once you have had the opportunity to review our responses to your comments. Should you have any questions, please call Guy Greenlee or Pierre Rivas at this office. LX- yours, William J. ~:Jtor WJM:PR:ayb Enclosure xc: U. S.

Attn: Paul Shillcock Envicom Corporation Attn: Woody Tescher - e Air Quality Responses to Comments: 1 . (a) The County plans to include recent ambient air quality levels for the last five (5) years to be compared with the National Ambient Air Quality Standards (NAAQS). (b) Please refer to Envicom Corporation's revised Air Quality Analysis which was forwarded to your office on November 5, 1986. Kern County's New Source Review Rule (NSR), Rule 210.1, is the core of the County's effort to manage air quality. The NSR requires individual evaluation of proposed projects on a project by project basis for any air contaminant for which there exists California or National Ambient Air Quality Control Standards~ Emissions in excess of 150 lbs./day require a level of control described as Best Available Control Technology (BACT). Emissions in excess of 200 lbs./day require a level of control described as Lowest Achievable Emissions Rate (LAER) plus mitigation of that air contaminant to zero lbs./day. The NSR is specifically designed to protect air quality within the project area as described above. (c) Based on the corrected emission figures and application of the NSR, modeling for ozone (03) and carbon monoxide (CO) are not warranted. Maximum hourly nitrogen dioxide (N02) levels (one of the two precursors to 03) has shown a downward trend since the late 1970's. The annual average N02 levels have also shown a steady decline and have leveled out in the last few years at roughly one-half the federal standard. With respect to carbon monoxide (CO), the maximum one-hour concentration has continued to decline with no exceedances of either state or federal standards since 1976~ The eight-hour average of CO levels has also continued to decline with only two exceedances of the state or federal standards since 1980, and no exceedances of either standard since 1982. The County of Kern has requested re-classification from non-attainment to attainment for CO by the EPA. In view of the revised emission figures and the current ambient air quality data, there will be no significant impacts imposed by CO concentrations. There is no documentation of CO exceedance of federal standards during the last four years. 2. The need for a more detailed mitigation proposals for air quality impacts would have been necessary with respect to the emissions presented in the original DEIS~ The revised 1 e e emissions do not warrant any greater detail in mitigations than those presented in the DEIS. 3. The emissions provided for HC, NO and CO were in great error (two orders of magnitude). For example, the Table 8 estimate of 863.9 tons/day NO has been corrected to 11.12 tons/day for the project. This figure represents the worst-case scenario for the maximum buildout in 15 years time. With the implementation of the NSR, the permiting process will, in reality, undoubtedly provide for much lower emissions. The project does not have the potential to exacerbate existing public health problems. NO and HC emissions have shown downward trends since the late 1970's. Given the revised emissions figures for the project, it is not projected to increase the current 03 problem. There has also been a substantial reduction in public exposure to ozone. The number of hours during which the federal ozone standard was exceeded has dropped from 90 hours in 1978-1980 to 43 in 1982-1984. This represents a reduction of 52 percent. The atmospheric reactions and meteorological conditions responsible for the formation of ozone are complex and incompletely understood. A model would need to simulate complex interactions within the county and account for pollutants entering from outside the county's northern border. A model of this magnitude is far beyond the scope of the proposed project. The emission figures for CO have been corrected. Total emissions for CO were revised from 211.6 tons/day to 45.8 tons/day per the correction of erroneous calculations. Attainment of the CO standard has been demonstrated and the County has requested re-classification from non-attainment to attainment by the EPA. 4. In view of the corrected emission figures, the project will not need to be included in the State Implementation Plan (SIP). The County of Kern portion of SIP is currently being revised and must legally comply with the Clean Air Act (CAA). The California Air Resources board (CARB) amended Kern County's Non-attainment Plan (NAP) during hearings on August 21-22, 1986. CARB Resolution 86-76 requires specific amendments to Kern County's Rules and Regulations by March 31, 1986, or CARB will effect the necessary changes by September 30, 1986. Hazardous Waste Responses to Comments 1. Although B. C. Chemical has filed for bankruptcy, the responsibility for site cleanup remains with B. C. Checmical. Current legal precedent places cleanup liability on B. C. Chemical before all creditors are to be paid. This case is currently on appeal in the U. S. District Court, the outcome of which may uphold or reverse this precedent. The 2 e e County of kern has reviewed and approved a site remedial investigation plan as prepared by a consultant. The Kern County Health Department has assumed lead agency status and has kept all appropriate state agencies informed. The Kern County Health Department will require that the B. C. Chemical site be remediated in such a manner as to allow for safe future development. The manner of remediation will, however, not be limited to any specific method. Although there have been allegations of drums having been buried on the B. C. Chemical property, as of today these claims have been unsubstantiated and no conclusive evidence exists to support them. The possibility of the existence of such drums will be explored when site investigation and remediation activities begin. The Kern County Health Department will monitor cleanup activities of a consultant and report to the State Department of Health Services. Regarding the Gariott Crop Dusting property, the City of Bakersfield is working closely with the Kern County Health Department (KCHD) and the Central Valley Regional Water Quality Control Board (RWQCB) to determine the total contamination on the airpark property itself. The California Department of Health Services (DOHS), as lead agency, issued a "Notice of Violation and Schedule for Compliance," Certificate Number P055345477, on July 31, 1986, to the Garriott Crop Dusting Company. This calls for a complete investigation of pesticide contamination on their property. From meetings with staff of the regulatory agencies, including the State DOHS, the RWQCB, and the KCHD, the City understands that the Garriott Crop Dusting Company has provided DOHS with a remedial investigation plan in accordance with the DOHS order. The City will continue to monitor action with respect to Garriott Crop Dusting, and will work closely with State agencies to address the problems on the affected areas of the adjacent airpark, which have been contaminated from activities on the Garriott Crop Dusting facility and from run-off from the Garriott Crop Dusting property. On its own initiative, the City of Bakesfield has retained consultants to advise them on investigation and future remediation of contamination on the affected City-owned property. To date, reconnaissance investigations have determined that some contamination exists on City property adjacent to Garriott, but the contamination is mainly restricted to the upper six (6) inches of soil. Minor contamination has been found to have migrated to a City-owned surface water sump which drains the polluted area. 1 e e Subject to a.pproval by the appropriate regulatory authorities, the City plans to remediate the minor contamination in the sump and close it. Through the construction of a new sump, up-gradient of Garriott Crop Dusting, the City has already eliminated the majority of water flow that passes over the contaminated area during storms. Final remediation of the affected area of the City property must be undertaken in conjunction with remediation of the source of contamination on the Garriott Crop Dusting property, with all parties working together to achieve the objective. Any further development on the affected area will contingent upon satisfactory cleanup of the site. the City will insure that the form of remediation such the site can be safely developed. 2. The City of Bakersfield intends to approach the Federal Aviation Administration (FAA) and recruit their involvement as a cooperating agency should a revised DEIS be prepared. be made Further, wi 11 be Water Quality Comment Responses 1. Since the airpark and the area immediately adjacent are within Improvement District #4 of the Kern County Water Agency and served by California Water Service, the allocation of Kern River water rights and its beneficial uses are not applicable. 2. Any groundwater recharge activities would be governed by Improvement District #4 of the Kern County Water Agency, in addition to any unlined canal losses incidental to their operations in the vicinity of the airpark. Water withdrawn for use in the airpark is currently taxed at a rate of $20.00/A.F. by Improvement District #4, and paid by the purveyor, California Water Service. 3. The airpark's domestic water ~upply is provided by California Water Service, therefore, any mitigating measures would be under the control of the purveyor. The County shall consult with the Kern County Water Agency and the California Water Service to formulate mitigation measures. 4. Groundwater beneath the Bakersfield Airpark is at a depth of approximately 190' and; therefore, contaminants present in the surficial soil are unlikely to pose an immediate threat to groundwater quality~ Minor contamination to sludges in the surface water sump, detected by the City's reconnaissance investigation, is not likely to pose a significant threat to groundwater at depth. No contaminants were detected in samples of groundwater recovered from wells in areas in the immediate vicinity of the affected portions of the airpark. 4 e . Further investigations to confirm that groundwater beneath the airpark has not been affected by surficial contamination will be a part of the State DOHS requirements for remedial investigation of the Garriott facility. The City will monitor these activities closely and coordinate their own on-going investigation with those performed on the Garriott facility. Recent tests of water samples taken from wells in the vicinity indicate no contamination of groundwater. Responses to Alternatives Comments I~ light of the revised air quality analysis and subsequent reduction in potential negative environmental impacts, we feel that the alternatives considered are sufficient. The Casa Lorna Specific Plan codified existing land use patterns and provides detailed development standards and policies for land use. The Specific Plan includes standards which are typically more restrictive than previous zoning and is consistent with the City's and the County's General Plan goals. e e 1700 Flower Street Bakersfield, California 93305 Telephone (805) 861·3636 KERN COUNTY HEALTH DEPARTMENT HEALTH OFFICER Leon,M Hebertson, M.D. ENVIRONMENTAL HEALTH DIVISION TO Pierre Rivas Community Development Richard Casagrande ~~ Hazardous Materials Manag~ent pr~ram Contact Staff: Amy Green DIRECTOR OF ENVIRONMENTAL HEALTH Vernon S.

William J. Mungary County of Kern Community Development Program Department 1415 18th Street, Second Floor Bakersfield, California 93301 Dear Mr. Mungary: The Environmental Protection Agency (EPA) has reviewed the Draft Environmental Impact statement (DE IS) titled CASA LOMA SPECIFIC PLAN AND FINAL ENTERPRISE ZONE APPLICATION, KERN COUNTY, CALIFORNIA. Our enclosed comments are provided in accordance with EPA's responsibilities under Section 309 of the Clean Air Act (CAA) and the National Environmental Policy Act (NEPA). We have classified this DEIS as Category EO-3, Environmental Objections - Inadequate Information (see attached "Summary of Rating Definitions and Follow-Up Action"). This rating is based on our review of the subject document for compliance and consistency with the CAA and NEPA. This DEIS is rated EO-3 because it lacks much of the information needed to assess the proposed project's impacts to air quality in Kern County. Also, it does not address the presence of hazardous substances at or near the Bakersfield Airpark. The development activities proposed under this action could pose a significant threat to the area's environmental quality. The DEIS does not adequately describe and analyze the potential adverse impacts to air quality and mitigation for these impacts. It also fails to address conformity with the State Implementation Plan, as required by the CAA. This area has reported numerous violations of the state and federal standard for ozone and experiences serious problems with carbon monoxide levels. Based on the emissions projections that were included in the DEIS, violations of the ozone standard would continue and probably increase due to a very substantial increase in nitrogen oxide emissions and a large increase in hydrocarbon emissions. . -2- . The DEIS does not discuss the presence of hazardous wastes and contaminated soils at or near the Bakersfield Airpark. EPA, state and local agencies are currently studying the extent and nature of the contamination in this area. This is an important concern because this site is designated for expansion and development in the specific plan and enterprise zone appli- cation. We are also concerned about potential adverse impacts to ground water quality from both hazardous waste migration and fluctuations in ground water recharge. It is important to relate the proposed action and alternatives to these problems and discuss measures to protect public health and environmental quality. EPA believes that a revised DEIS should be prepared to address these concerns and distributed for public review. The revised DEIS shoùld thoroughly analyze ways to avoid or mitigate potential adverse impacts to environmental quality and public health from proposed development activities. This may involve study of alternatives outside the spectrum of alternatives presented in the DEIS. If these issues are not adequately resolved prior to the Final EIS, this proposal could be a can- didate for referral to the Council on Environmental Quality (CEQ)~ ~s you know, we have had numerous discussions with members of your staff and representatives from the City of Bakersfield. These discussions have been useful in clarifying the nature of the proposed action. We look forward to continuing this type of interaction and to reviewing ongoing environmental studies and subsequent NEPA documentation. The classification and date of EPA's comments will be published in the Federal Register in accordance with our public disclosure responsibilities under Section 309 of the Clean Air Act. If you have any questions, please contact Enrique Manzanilla, Federal Activities ~ranch, at (415) 974-0948 or FTS 454-0948. Sincerely, J Øf¿¡¡~ Regional Admlnistrator Enclosure (6 paqes) cc: A.

Activities under the proposed plan and Enterprise zone will increase air pollution and exacerbate public health problems; and 4) The DEIS does not address conformity with the State Imple- mentation Plan (SIP) and appears to be in conflict with the Clean Air Act (CAA). 1. Lack of Adequate Data and Impact Analysis: The DEIS does not adequately describe what impacts the project will have on air quality. For all alternatives, the revised DEIS should: a) Provide recent ambient air quality levels and compare them to the National Ambient Air Quality Standards (NAAQS). b) Provide a quantitative description of projected future ambient air quality conditions in the project area (including the project). The DEIS' information on emission increases is unclear. Table 8 does not clearly show total emission increases, contains arithmetic errors, and fails to indicate the percentage increase for each pollutant (DEIS, p. 4-41). An explanation of how emission increases were estimated, including assumptions, emission factors, etc., should be included in the revised DEIS. The revised DEISshould explain Kern County's New Source Review (NSR) Rule and how it will affect stationary pol- lution sources. It should also provide emission increase estimates that reflect applicatiõn of the Rule. The proponents should be aware that the NSR Rule could seri- ously limit the potential for industrial development. The Kern County Air Pollution Control District should be contacted for more information. e -2- e c) Include air quality modeling for 03 and carbon (CO) to assess potential air quality impacts. assessment is a critical component of any EIS. revised DEIS should specify the model used, as the inputs and assumptions required to run the monoxide Impact The well as model. The revised DEIS should evaluate the potential for violation of NAAQS for 03 using methodologies recently applied in Kern County for the Nonattainment Area Plan (NAP) update with the most recent emissions input data for 03 precursors [i.e., NOx and hydrocarbons (HC)]. The analysis should be performed with and without project conditions. Either the California Air Resources Board or the EPA Regional Office, Air Management Division, can provide guidance on modeling for 03. The revised DEIS should also evaluate for violations of NAAQS for CO, using techniques given in Carbon Monoxide ~ Spot Guidelines EPA-450/3-78-033,-034, -035, -036, -037, -040 (August 1978). In most cases, the 8-hour standard is the controlling factor. If concentrations of CO are determined not to be significant, then the data to support this conclusion must be presented. If projections for CO concentrations are determined to have significant impacts, then a more sophisticated model, such as EPA's HIWAY Model or the California Department of Transportation's CALINE 3 Model, should be employed. The CO microscale analysis should include project construction and development activities plus estimated background levels at identified reasonable receptor sites for all alternatives, using worst-case meteorology. The derivation of the background levels used in the analysis must be clearly described. The results of the CO analysis should be compared to the appropriate federal and state air quality standards. 2. Inadequate Mitiqation: The DEIS includes a one page list of possible mitigation measures on page 4-44. The revised DEIS should provide far more detailed proposals, quantify and assess the effects of mitigation, and include an Imple- mentation Plan (IP) which describes the specific implemen- tation commitments. It should contain specific design cri- teria and describe how the IP's proponents will ensure completion of the mitigation. 3. Air Quality Impacts and Public Health: Severe air pollution problems already exist in Kern County. If projections listed in Table 8 are correct, this project has the potential to seriously exacerbate existing public health problems. The DEIS indicates there will be large increases in emissions of HC, NOx and co. For example, table 8 estimates NOx e e -3- emissions of approximately 866 tons/day for the project. Current NOx emissions are approximately 250 tons/day in Kern County. NOx and HC are the primary precursors which form 03. In 1985, Kern County reported 27 violations of the federal 03 standard and 112 violations of the state standard. These violations will continue and probably increase under the proposed projects. A revised 03 control plan was recently adopted by the California Air Resources Board (August, 1986) because of the severity of the 03 problem. Attainment of the 03 standard will not occur by 1987. CO pollution is also a health problem and the proposed project would almost double these emissions. Attainment of the CO standard has not been demonstrated (DEIS, p. 4-35). 4. Conflicts with the CAA: The DEIS does not address conformity of the project with the SIP. Section 176(c) of the CAA prohibits any federal participation in any action unless it is specifically found to conform to the SIP. The federal agency proposing the action is required by the CAA to assess conformity. Existing information indicates that the proposed actions are not included in the SIP and do not conform. The DEIS needs to be revised to assess ëõnformity, including the following: a) Consistency with SIP assumptions for emissions growth: b) Inclusion of and consistency with all SIP policies, mea- sures and requirements. The revised DEIS should address project consistency with the transportation control measures in the SIP and the Regional Transportation Plan: c) Assessment of whether the project will interfere in any way with attainment of the National Ambient Air Quality Standards: and d) Mitigation of all emission increases and problems not covered by the SIP. Hazardous Waste Comments 1. EPA is concerned about the proposed development of the Bakersfield Airpark and surrounding areas. The DEIS does not discuss past activities and soil contamination in the area. This airpark has been used for years as a cropdusting base, and soil samples taken there in June of 1986 reveal soils contaminated with pesticides and chlorinated hydro- carbons. - -4- e The Garriott Cropdusting facility at 2010 South Union Avenue is currently under investigation by the Kern County Health Department (KCHD), the Central Valley Regional Water Quality Control Board (RWQCB), and the California Department of Health Services (DHS). Soils at this site are contaminated with ethyl parathion (350 ppm) and other pesticides. The natural drainage of the area runs from the airpark through the Gariott facility and off. So far there has been no contamination found in nearby wells, but sampling is ongoing. DHS and KCHD issued a site mitigation directive here, but the facility's proposal for site characterization was turned down as being inadequate on 8/22/86. KCHD should be contacted at (805) 861-3636 for more information regarding this action. The B.C. Chemicals facility (1511 S. Union Avenue) has also improperly disposed of hazardous chemicals. Although some cleanup has taken place here, there are still drums buried on-site and an unknown amount of soil contamination. Very little is known about the nature and extent of conta- mination at these sites, but it is clear that soils at and around the airpark are contaminated with pesticides and other hazardous chemicals. It is important that the revised DEIS relate the proposed action.and alternatives to these problems and discuss measures to protect public health and environmental quality during proposed development activities. It would be unwise to disturb soils in the area until a thorough investigation has been undertaken which can deter- mine the best method for their removal and/or treatment. EPA recommends extensive coordination with KCHD, DHS, and the the RWQCB. 2. Because of the Federal Aviation Administration's (FAA) past and continuing involvement in the Airpark's expansion, we believe the City of Bakersfield should request FAA's participation as a cooperating agency (see 40 CFR 1501.6) in the preparation of the revised DEIS. The DEIS (p. 3-10) states that "the Airpark expansion will include utilization of $14 million granted by the FAA to assist in property and facility acquisition..." We believe this expenditure of of funds is a major federal action. In addition, reports of soil contamination and the presence of hazardous waste constitutes new information which should be assessed before resources ar~rretrievably committed. Water Quality Comments: 1. The revised DE IS should discuss whether water rights allo- cated by the City of Bakersfield or Kern County will impact the beneficial uses of the Kern River. Also, the e -5- e water rights allocation should be shown as a measurement per annum. 2. The revised DEIS should state how frequently the ground water will be recharged on an annual basis. will the water allocated for ground water recharge be equivalent to the ground water withdrawn? 3. The revised DEIS should specifically address any other mitigating measures which will be taken by the City of Bakersfield or Kern County if the State Water Project does not allocate additional water for ground water recharge. 4. Historic uses of the Bakersfield Airpark have resulted in the disposal of hazardous wastes and the contamination of soils (see Hazardous Waste Comments). The potential migration of hazardous chemicals to surface and ground water should be discussed in the revised DEIS. It should also discuss the adverse impacts that could occur under each of the alter- natives and the potential mitigation measures for those impacts. Alternatives Comments 1. The range of alternatives considered in the DEIS is extremely limited. It is unclear whether environmental factors were considered in establishing the range of alternatives and in subsequent analyses of the alternatives. Table 9 of the Alternatives Study (DEIS, appendix B - p. 4-2) lists the "evaluative criteria" used in ranking land use alternatives for the Casa Lorna Specific Plan. Except for "Noise Impacts," no other environmental factor was used to evaluate land use alternatives for the Specific Plan. Also, protection of agricultural lands was the only environmental factor considered in changing the Enterprise Zone designation to the Reduced Program alternative. Given our concerns over the proposed project's effect on environmental quality, it is important that the DEIsconsi- der all reasonable alternatives by thoroughly assessing both socio-economic and environmental impacts in the short and long term. If alternatives are eliminated from detailed study, the revised DEIS should discuss the reasons for their elimination [40 CFR IS02.14(a)].

Environmental Protection Agency 215 Fremont Street San Francisco, California 94105 ATTENTION: Mr. Enrique Manzanilla RE: Cas a Lorna Specific Plan and Final Enterprise Zone Application Draft Environmental Impact Statement SCH No. 85051304 Dear Ms. Ayres: The County of Kern Community Development Program Department has received and reviewed your comments dated Octoher 27, 1986 regarding the Casa Loma Specific Plan and Final Enterprise Zone Application Draft Environmental Impact Statement (DEIS). Enclosed are our responses to your comments. A major concern with the DEIS is the oroposed oroject's impacts to air quality in Kern County. After review of the Air Quality Analysis section of the DEIS by our staff and the consultants who prepared the DEIS, it was learnerl that gross errors in projection figures had been made. The consultants have revised the air quality data and included all assumptions used in their analysis in a "Revised Air Quality Analysis" for'vJòrded to EPA on November 5, 1986, for review by EPA, Air Man0qement Division staff. It is our contention that in light of the revised data much of the concern over air quality impacts no longer a p p 1 i e s. The omission of the presence of hazardous suhstances at the Bakersfield Airpark is primarily due to the fact that the situation was not known by us or the consultant during the preparation of the environmental document prior to its adoption òs a Final Environmental Impact Report on January 15, 1985. In reference to the Garriott Crop Dusting facility at 2010 South Union Avenue, Garriott Crop Dusting contracted with a consultant who has submitted their report to the State Oepartment of Health e e r~ s. J u d i thE. A Y res Page 2 January 14, 1987 Services (BOHS) for evaluation. Initial reports from the Garriott's consultant indicate that the public is not at a health risk given the proper remedial actions are carried out by the City, County and other responsible parties. The City of Bakersfield has also contracted with a consultant and a final report has been prepared. The contamination problem at the B. C. Chemicals facility located at 1511 South Union Avenue was referred to the State of California since B. C. Chemical's filing of Chapter 11. The County of Kern will assume the responsihlity of monitoring the progress of the State in their efforts for cleanup. This department in cooperation with other local aovernment entities and consultants is prepared to address all issues raised by EPA and proposes to proceed with the preparation of a revised DEIS should it prove to be warranted. We look forward to scheduling a meeting with EPA staff once you have had the opportunity to review our responses to your comments. Should you have any questions, please call Guy Greenlee or Pierre Rivas at this office. Very truly yours, William J. Mungary, Director WJM:PR:ayb Enclosure xc: U. S. Dept. of Housing and Urban Development Environmental Clearance Office, Attn: Ceferino Ahuero Kern County Air Pollution District Attn: Clif Calderwood Kern County Dept. of Planning and Developmental Services Attn: Fred Simon City of Bakersfield, Each Council ~ember Attn: City Clerk City of Bakersfield, City Manager's Office Attn: Mary Strenn City of Bakersfield Fire Department Attn: Dennis Needham City of Bakersfield Economic Development Dept. Attn: Paul Shillcock Envicom Corporation Attn: Woody Tescher Kern County Environmental Health Services, Hazardous Waste Program, Attn: Richard Casagrande e ,e Air Quality Responses to Comments: 1 . (a) The County plans to include recent ambient air quality levels for the last five (5) years to be compared with the National Ambient Air Quality Standards (NAAQS). (b) Please refer to Envicom Corporation's revised Air Quality Analysis which was forwarded to your office on November 5, 1986. Kern County's New Source Review Rule (NSR), Rule 210.1, is the core of the County's effort to manage air quality. The NSR requires individual evaluation of proposed projects on a project by project basis for any air contaminant for which there exists California or National Ambient Air Quality Control Standards. Emissions in excess of 150 lbs./day require a level of control described as Best Available Control Technology (BACT). Emissions in excess of 200 lbs./day require a level of control described as Lowest Achievable Emissions Rate (LAER) plus mitigation of that air contaminant to zero lbs./day. The NSR is specifically designed to protect air quality w~thin the project area as described above. (c) Based on the corrected emission figures and application of the NSR, modeling for ozone (03) and carbon monoxide (CO) are not warranted. Maximum hourly nitrogen dioxide (N02) levels (one of the two precursors to 03) has shown a downward trend since the late 1970's. The annual ave~~e N02 levels have also shown a steady decline and ~leveled out in the x last few years at roughly one-half the federal standard. With respect to carbon monoxide (CO), the maximum one-hour concentration has continued to decline with no exceedances of either state or federal standards since 1976. The eight-hour average of CO levels has also continued to decline with only two exceedances of the state or federal standards since 1980, and no exceedances of either standard since 1982. The County of Kern has requested re-classification from non-attainment to attainment for CO by the EPA. In view of the revised emission figures and the current ambient air quality data, there will be no significant impacts imposed by CO concentrations. There is no documentation of CO exceedance of federal standards during the last four years. 2. The need for a more detailed mitigation proposals for air quality impacts would have been necessary with respect to the emissions presented in the original DEIS. The revised e e emissions do not warrant any greater detail in mitigations than those presented in the DEIS. 3. The emissions provided for HC~ NO and CO were in great error (two orders of magnitude)~ For example, the Table 8 estimate of 863.9 tons/day NO has been corrected to 11.12 tons/day for the project. This figure represents the worst-case scenario for the maximum buildout in 15 years time. With the implementation of the NSR, the permiting process will, in reality, undoubtedly provide for much lower emissions. The project does not have the potential to exacerbate existing public health problems. NO and HC emissions have shown downward trends since the late 1970's. Given the revised emissions figures for the project, it is not projected to increase the current 03 problem. There has also been a substantial reduction in public exposure to ozone. The number of hours durinq which the federal ozone standard was exceeded has dropped for 90 hours in 1978-1980 to 43 in 1982-1984. This represents a reduction of 52 percent. The atmospheric reactions and meteorological conditions responsible for the formation of ozone are complex and incompletely understood. A model would need to simulate complex interactions within the county and account for pollutants entering from outside the county's northern border. A model of this magnitude is far beyond the scope of the proposed project. The emission figures for CO have been corrected. Total emissions for CO were revised from 211.6 tons/day to 45.8 tons/day per the correction of erroneous calculations. Attainment of the CO standard has been demonstrated and the County has requested re-classification from non-attainment to attainment by the EPA. 4. In view of the corrected emission figures, the project will not need to be included in the State Implementation Plan (SIP). The County of Kern portion of SIP is currently being revised and must legally comply with the Clean Air Act (CAA). The California Air Resources board (CARB) amenderl Kern County's Non-attainment Plan (NAP) during hearings on August 21-22, 1986. CARB Resolution 86-76 requires specific amendments to Kern County's Rules and Regulations by March 31, 1986, or CARB will effect the necessary changes by September 30, 1986. Hazardous Waste Responses to Comments 1. >~- ./ Since B.C Chemical has filed for bankruptcy, the improperly disposed of hazardous chemicals on their site became the responsibility of the State of California. The County of Kern will work with the State to insure that this site is properly decontaminated as quickly as possible. e e Until such time as the chemicals are properly disposed of, the County will insure that no construction or other d eve lop men t will b e u n d e r t ak e non the sit e . Fur the r, t h e¿E- 7 County will require that final r~ediation will ~ be completed in a manner that would~allow re-excavation of the hazar~~~chemicals. The form of remediation will be such that the B.· C. Chemical site can be safely developed in accordance with plans for the area. The scheduling of any planned development will be made contingent upon satisfactory clean-up of the subject site. In summary, the County will monitor the activities of the State of California Department of Health Services in their efforts to clean up the referenced site; the County will prevent any development on the site until the problem is resolved; and the County will insure that the form of remediation will be such that the ß. C. Chemical site can be safely developed. Regarding the Gariott Crop Dusting property, the City of Bakersfield is working closely with the Kern County Health Department (KCHD) and the Central Valley Regional Water Quality Control Board (RWQCB) to determine the total contamination on the airpark property itself. Meanwhile, the California Department of Health Services (DOHS), as lead agency, issued a "Notice of Violation and Schedule for Compliance," Certificate Number P055345477, on July 31, 1986, to the Garriott Crop Dusting Company. This calls for a complete investigation of pesticide contamination on their property. From meetings with staff of the regulatory agencies, including the State DOHS, the RWQCB, and the KCHD, the City understands that the Garriott Crop Dusting Company has provided DOHS with a remedial investigation plan in accordance with the DOHS order. The City will continue to monitor action with respect to Garriott Crop Dusting, and will work closely with State agencies to address the problems on the affected areas of the adjacent airoark, which have been contaminated from activities on the Garriott Crop Dusting facility and from run-off from the Garriott Crop Dusting property. On its own initiative, the City of Bakesfield has retained consultants to advise them on investigation anrl future remediation of contamination on the affected City-owned property. To date, reconnaissance investigations have determined that some contamination exists on City property adjacent to Garriott, but the contamination is mainly restricted to the upper six (6) inches of soil. One two foot test hole showed more significant contamination to a depth of 18 inches. Contamination exists at depths greater than 6 inches but of much less intensity. Minor contamination has ..., e e been found to have migrated to a City-owned surface water sump which drains the polluted area. Subject to approval by the appropriate regulatory authorities, the City plans to remediate the minor contamination in the sump and close it~ Through the construttion of a new sump, up-gradient of Garriott CroD Ousting, the City has already eliminated the majority of water flow that passes over the contaminated area during storms. Final remediation of the affected area of the City property must be undertaken in conjunction with remediation of the source of contamination on the Garriott Crop Ousting property, with all parties working together to achieve the objective. Any further development on the affected area will be made contingent upon satisfactory clean-up of the site. Further, the City will insure that the form of remediation will be such the site can be safely developed. The City of Bakersfield intends to approach the Federal Aviation Administration (FAA) and recruit their involvement l as a cooperating agency should a revised DEIS be prepared. Water Quality Comment Responses 2. 1. Since the airpark and the area immediately adjacent are within Improvement District #4 of the Kern County Water Agency and served by California Water Service, the allocation of Kern River water rights and its beneficial uses are not applicable. 2. Any groundwater recharge activities would be governed by Improvement District #4 of the Kern County Water Agency, in addition to any unlined canal losses incidental to their operations in the vicinity of the airpark. Water withdrawn for use in the airpark is currently taxed at a rate of $20.00/A.F. by Improvement District #4, and paid by the purveyor, California Water Service. 3. The airparkls domestic water supply is provided by California Water Service, therefore, any mitigating measures would be under the control of the purveyor. The County shall consult with the Kern County Water Agency and the California Water Service to formulate mitigation measures. ., 4. Groundwater beneath the Bakersfield Airpark is at a depth of approximately 1901 and; therefore, contaminants present in the surficial soil are unlikely to pose an immediate threat to groundwater quality. Minor contamination to sludges in the surface water sump, detected by the City's reconnaissance investigation, is not likely to pose a significant threat to · e groundwater at depth. No contaminants were detected in samples of groundwater recovered from wells in areas in the immediate vicinity of the affected portions of the airpark. Further investigations to confirm that groundwater beneath the airpark has not been affected by surficial contamination will bea part of the State DOHS requirements for remedial investigation of the Garriott facility. The City will monitor these activities closely and coordinate their own on-going investigation with those performed on the Garriott facility~ Recent tests of water samples taken from wells in the vicinity indicate no contamination of groundwater. Responses to Alternatives Comments In light of the revised air quality analysis and subsequent reduction in potential negative environmental impacts, we feel that the alternatives considered are sufficient. The Casa Lorna Specific Plan codified existing land use patterns and provides detailed development standards and policies for land use. The Specific Plan includes standards to supplement existing zoning and is consistent with the City's and the County's General Plan goals. e . .~ 1700 Flower Street Bakersfield, California 93305 Telephone (805) 861-3636 k..:RN COUNTY HEALTH DEPARTMEN'.

CHEMICAL COMPANY SITE REMEDIAL INVESTIGATION PLAN 1.0 INTRODUCTION 1.1 Project Overview The project site is located at 1511 S. Union Avenue, Bakers- field, California (see Figure 1), and contains an estimated 6,000 drums and chemical containers. These drums are in various conditions, ranging from full to empty, some are clearly labeled while others are not, and some are physically intact while others are damaged. In addition to the drums, the si te has several 1 arge storage tanks, and some chemi ca 1 processing equipment. At various locations at the site there is evidence of spills (discolored soils), and some spills may have migrated a short distance off site. In addition to chemical containers, the site has three build- ings. One is a small open sided structure formerly used as a di ese1 engi ne repai r shop. The others are warehouses, and contain unopened packages of chemicals, some of which are in a re-useab1e form. B.C. Chemicals handled a wide range of materials. Appendix A gives their product list, together with some relevant Mater- ials Safety Data Sheets. 1 emcon Associates IDNQARO RD.

CHEMICALS BAKERSFIELD, CALIFORNIA SITE MAP FIGURE ·2 PROJECT NO. 773-01.01 2.1.2 Regional Hydrogeology Published data on the regional geology and hydrogeology will be researched. Typical sources include publications of the U.S. Geological Survey, records and publications of the State Department of Water Resources (DWR) and local authorities (for example Kern County Water Agency, Improvement District NO.4). From the data so obtained, a narrative description of the surface and subsurface geology and hydrogeology wi 11 be pre- pared. Included in the description will be appropriate draw- ings, geologic cross sections, and maps. 2.1.3 History of Chemical Usage A wide range of chemicals were handled on this site. Appen- dix A lists the products that were sold by B.C. Chemicals, and inadditi on to these, there may have been compounds used in formulations, and/or intermediaries and by-products. The former owner of B. C. Chemi ca 1 s wi 11 be i ntervi ewed to establish the overall history of the site, and to identify any additional chemicals that should be included in the listing. To the extent that former employees of B.C. Chemicals can be reached, they too will be interviewed. 8 em<on Rssociates 2.1.4 Disposal Activities and Spills While conducting the interviews proposed above, a history of disposal activities and spills will also be obtained. To the extent that thi s hi story may be sparse or non-exi stent, an inventory of applicable environmental permits will be obtained, and agency records searched for notices of violation or similar records. A narrative description will be prepared including, where possible, quantities and characteristics of liquid and solid wastes, as well as spills. 2.1.5 Suspected Contamination Areas Since the PI has only consisted of walk through inspections, there is currently no analyti cal data avail abl e on suspected soil and ground-water contamination. There is significant surface staining in several areas, both on-site and off-site. These areas will be defined in develop- ing the site plot plan (see Section 2.1) and definition of extent of contamination will be an objective of the sampling plan presented in Section 6 below. 2.1.6 Past Remedial Actions The only known remedial actions that have occurred, or might occur prior to implementation of the RI, are the removal of salvageable chemicals and some interim mitigation measures designed to control storm water run-off. The extent to which these activities have occurred will be documented and verified. 9 emcon Rssociates 2.2 Quality Control/Quality Assurance (QA/QC) Plan 2.2.1 Sampling QA/QC Prior to field entry a QA/QC plan for sampling soils, waters and drums wi 11 be prepared for revi ew and approval by Kern County Hea lth Depa rtment ( CHD) . As a mi n i mum, th is wi 11 include: · Equipment calibration and maintenance procedures. · Sample collection procedures. · Chain-of-custody procedures. · Sample preservation procedures. Unt il more site characteri zat i on has been carri ed out, it is not possible to specify precise methodologies. However, generic guidelines will be used. A typical example is given in Appendix C. 2.2.2 QA/QC Aspects of Laboratory Analysis All samples will be sent to a State approved and certified laboratory for analysis. Standard methodologies will be used, as appropriate, using the following protocols given in Table 1. The 1 aboratory QA/QC pl an wi 11 adhere to the requi rements of Section 3.5.2.d of the California Site Mitigation Decision Tree. 10 emcon Rssociotes e e TABLE 1 RECOMMENDED AND REQUIRED SAMPLING AND ANALYTICAL METHODS CAC, TITLE 22, ARTICLE 11 1.

This plan will be implemented and updated to cover specific activities that will be carried out during the RI. These include: · drum sampling and characterization · exploratory soil borings · equipment decontamination and dismantling · removal and disposal of chemicals and drums For each area the pl an will address the foll owi ng issues in detail : · protective equipment · training · on-site monitoring · base-line health surveillance 2.3.2 Community Safety The site safety plan revisions will address community safety issues such as the possibility of off-site dispersal of hazardous or toxic materials. Issues to be addressed in more deta il i nc 1 ude : · site access control · off-site air monitoring · contingency planning 12 emcon Associates 2.4 Community Relations and Notification As part of the Remedial Investigation, a Community Relations and Notification Plan will be prepared. This plan will address the fo 11 owi ng items: A. Public notification via any and all of the following techniques: · newsletters · community meetings · project reviews · technical briefings · telephone hotline B. Desirability of an information repository. If warranted, a central depository will be designated either at a local public 1 i brary, or some other nei ghborhood facil ity such as a hi gh school. C. Public meetings. If public awareness and concern warrants, public meetings will be held, either at specific critical points during remedial action, or on a routine regular basis. Information will be disseminated via graphic displays, slide presentations, and technical briefings designed to translate potentially complex technical information in terms understandable by lay people. 13 emcon Associates 2.5 Sampling Plan Figure 4 shows a preliminary environmental assessment of the site, based on a walk through inspection. The sampling plan must address the following issues: A. Nature and type of surface contamination. B. Extent and nature of soil contamination. C. Extent and nature of potential ground-water contamination. D. Nature, type and quantity of residual chemicals contained in drums, tanks and equipment on site. 2.5.1 Surface Sampling 2.5.1.1 Dirt Piles Three pil es of di rt are present on site. These pil es were created by scrapi ng the superfi ci al soil into pil es by means of a bull dozer. The soi 1 s do not appear to be hi ghly hazardous and do not appear to requi re speci al precaut ions in handl i ng. If these pil es have not been removed during preliminary site mitigation, the soils will be sampled and analyzed. Representati ve sampl es wi 11 be obtai ned by hand cori ng and mixing the cores to obtain a representative sample. These samples destined for inorganic analysis will be placed in plastic bags, labelled and delivered to a State certified laboratory for analysis. Chain-of-custOdy pro- cedures will be used throughout. Samples for organic and 14 emcon Rssociates '''O"ICT NO, 773-01.01 4 WILLIAMS ~ WILLIAMS, INC. REMEDIAL INVESTIGATION PLAN B. C.

The rings will be sealed, labelled and sent to the labora- tory. The representative sample from each pile will be analyzed for the toxic metals known to have been on-site. These are: · ·barium · chromium (total and hexavalent) · cobalt · copper · vanadium · zinc · nickel The analysis will be carried out by nitric acid extrac- tion and total metal concentration determined. If ten percent of the metal concentration exceeds the STLC value given in CAC Title 22, Division 4, Section 66696, then the WET extraction procedure (Section 66700) will be used to determine the IIsolublell or lIextractablell metal concen- trations. Since many of the chemicals used on-site were acids, alkalis or salts, the following two tests will be carried out to identify potential contamination: . pH . soil conductivity 16 emcon Rssociates Examination of the soils for organic chemical contamina- tion presents a problem, in that so many different types of material were used on-site. While it is technically feas i b 1 e to analyze for each and everyone, the costs would be extraordinarily high and perhaps yield little or no information. Many of the organic materials are not highly toxic and will have a relatively short life in the environment. These include the esters, glycols, ketones and alco- hols. However, other organic chemicals are more toxic and, some environmentally persistent. These may repre- sent a public health or environmental hazard and include the organic amines, pesticides, chlorinated solvents, non-chlorinated solvents and miscellaneous materials such as formaldehyde and organic mercaptans. In order to profile this range of compounds at a reason- able cost, it is proposed to analyze one each of the soil samples from each pile for: · chlorinated hydrocarbons · volatile organic compounds (EPA Method 624) · total recoverable petroleum hydrocarbons (EPA Method 418.1) Research into the chemical nature of some of the materials currently only identifiable under trade-names (i.e., Triton M-10 or Oowicide G) will be carried out to see of other analyses should also be performed (i.e., a pesticide/PCB screen). 17 emcon Associates emcon Associates 2.5.1.2 Stained Surface Areas There are a number of areas showing superficial staining, both off-site and on-site. Surface samples representing the interval 0"-3" will be obtained at the locations marked on Figure 4. These 24 locations represent both suspect and non-suspect areas, and together will provide a good profile of the overall surface conditions on the site. The chemical analyses will be the same as those proposed above for the soils from the dirt piles. 2.5.2 Soil Sampling Program In order to determi ne the extent and depth of poss i b 1 e soil contami nati on, seven exploratory bori ngs wi 11 be dri 11 ed at the locations shown on Figure 4. These sites represent areas of obvious superficial contamination and the exploratory boring, soil sampling and analysis will demonstrate the extent of vertical contamination. Additional exploratory borings may be requi red and the need or otherwi se wi 11 be determi ned by the results of the surface soil analyses performed under section 2.5.1.2. The results will also be used to guide the analytical program, and only those pollutant parameters identified in a surface sample will be sought in the depth profile. The following methodologies will be used in the exploration. All drilling equipment including bits, augers, samplers, etc., wi 11 be steam cleaned pri or to commencement of fi e 1 d activities and between each boring.- 18 emcon Associates A detailed boring log will be recorded for each boring from undisturbed soil samples obtained at 5-foot intervals and drill cuttings. Soil samples will be obtained from each bori ng begi nni ng at a depth 5 feet below the ground surface and continuing at 5-foot intervals until ground water is encountered or a depth of 40 feet is reached. A modifi ed Cal iforni a spl it-spoon sampl er will be used to coll ect the soil samples. The sampler will be dri ven 18 inches into undisturbed ground beyond the tip of the augers by a 140-pound hammer with a 30-inch drop. The sampler will be withdrawn from the boring and the undisturbed soil samples removed in 4- inch long brass liners. Soil samples obtained above the water table will be retained in the brass liners, sealed in aluminum foi 1 and gl ass jars, and stored on ice for transport to the laboratory. Labels will be placed on the jars identifying the project number, date, sampler's initials, boring number, and sampling depth. In addition, each soil sample will be recorded on a chain-of-custody form identifying the soil sample number, sampler's initials, date, any couriers used, and responsible laboratory personnel. If ground water is not encountered, each bori ng will yi e 1 d eight soil samples for analysis. Depending on the results of the surface sampling program and field observations (i.e., stained or odiferous soils) these samples may be analyzed either separately, or as composites. For estimating purposes it is assumed that a composite from each boring will be analyzed for the same range of parameters listed in Section 2.5.1.1 above. All samples not immediately submitted for analysis will be archived by EMCON under refrigeration for possible additional analysis. 19 emcon Rssociates It is not anticipated that there will be a need for project specific analytical techniques or QA/QC methods, and Health and Safety protocols not already detailed elsewhere in this plan. 2.5.3 Ground-Water Sampling In July of 1984, usable ground water in the regional uncon- fi ned aqui fer was at an el evati on of approximately 190 feet above mean sea level (MSL), (Source: Kern County Water Agency, Improvement District No.4). The site surface e1 evati on is approximately 385 feet MSL, gi vi ng a depth to ground water of about 200 feet. Ground-water contours for July, 1984 show a very shallow hydraulic gradient to the east or southeast (see Figure 5). There are approximately 21 active wells within one mile of the site (see Figure 6) and five inactive wells. The nearest active well is approximately 2,000 feet to the west (i.e., it is upgradient) while the nearest wells downgradient (east and/or southeast) are approximately 5,000 feet away. There is a significant well field adjacent to the Central Branch Canal, approximately 3,000 feet to the south. As part of the RI, the above data wi 11 be veri fi ed as bei ng still accurate, and water quality records obtained for the wells within a one mile radius of the site. If the 1330 program has been carri ed out, specifi c know1 edge of specifi c priority pollutant contamination (if any) will be available. If the data is not available, or if major data gaps exist, the nearest well s to ttle west, east, southeast and south wi 11 be sampled and the water analyzed for the priority pollutants and for chlorinated hydrocarbons. 20 emcon Associates " , I \ I \ ·31-- . 1-- ---;)2-·· i I \ ~ ~ ~ : -, ~; I \ - -!-- ---33--· \ ' ! --_._. .-. -.- , : -- !

If ground water is encountered above 40 feet duri ng the explor- atory bori ngs, the bori ngs will be converted to 4-i nch mon- itoring wells. Figure 7 shows a typical well detail. Final construction decisions will be made in the field when depth to perched ground water is known. Foll owi ng construction of the ground-water monitori ng well s, each well will be developed using a submersible pump. A minimum of one bore volume will be removed to ensure that any material introduced during the drilling operation is removed. A bore volume is calculated to include the casing volume and the void volume in the sand pack. All wells will be protected from fluid entry, accidental damage, and unauthorized access by securing the well-head below ground surface in a concrete vault box and installing a water-tight casing cap and locking device. Prior to sampling, all equipment to be placed in the well or to come into contact with the ground water will be dis- assembled and thoroughly cleaned. Pump blanks will be obtained from the submersible pump after ~leaning, by pumping deionized organic-free water through the sampling assembly. A minimum of one bore volume of ground water will be removed from the wells to ensure that a representative sample can be obtained. 23 emcon Associates ï m .1 Steel protective casing (StdJ EXPLORATORY BORING a.

All samples will be collected in dupli- cate. Ground-water samples will be labeled and then placed on ice for delivery to the laboratory. A chain-of-custody form will accompany the water samples. The samples will be analyzed for chlorinated hydrocarbons, benzene, toluene and xylenes (BTX) as an initial step, using chlorinated hydro- carbons and BTX as surrogates for all poss i b 1 e contami nants. If contamination is found additional analyses will be carried out for the priority pollutants. If shallow ground-water wells are installed, the elevation and hydraulic gradient of the perched water will be obtained. Downgradient monitoring wells are required to determine if contamination exists. One deep well will be installed down- gradient of the site (see Figure 4). This well will penetrate the usable aquifer (~200 feet deep) and be constructed of 4-inch PVC pipe. The well casing will penetrate 20 feet into the first water bearing zone or to the top of a confining bed which could serve as a hydraulic barrier to lower aquifers if one is encountered shallower than 20 feet into the first aquifer. The well screen, or perforated interval, will con- sist of slotted PVC pipe and will be that portion of the cas- ing which is in the first 20 feet of the water bearing zone or to the top of a confining unit. A gravel pack filter will be installed between the hole and the slotted casing to 10 feet above the top of the perforated interval. A bentonite and cement ,grout seal will be placed on top of the gravel pack and the remai nder of the annul ar space will be fill ed to 30 feet from the top of the hole with bentonite. A surface seal at least 30 feet thick will be installed to ground surface. 25 emcon Associates If shallow perched ground water exists, a downgradient location will be chosen and a monitoring well installed. Details of location and construction will be made after field conditions have been ascertained. As before, water samples will be obtained and analyzed for chlorinated hydrocarbons. If the results of the ground-water monitoring program results in data showi ng contami nat i on above the State Action Levels, the results will be reviewed with the Kern County Health Department and the Kern County Water Di stri ct and suitable acti on for further monitori ng and/or conti ngency pl ans for alternative water supplies developed. A summary of proposed soil and ground-water sampling is shown in Table 2. 2.5.4 Drum Sampling An initial survey of the drums on-site has established the approximate inventory shown in Table 3. Many of the drums are in good condition, are clearly marked, and appear to be new supplies and products that were never delivered to custo- mers. Many of these drums may be salvageable. 26 emcon Associates TABLE 2 SUMMARY OF FIELD SOIL AND WATER SAMPLING PLAN Matrix Number of Samples 3 Analyses Metals, VOA, Chlorinated and non-chlorinated hydrocarbons* Comment Di rt Pil es Only 3 piles present. e Surface Soil s 24 II 9 in stained areas. 15 elsewhere including off-site.

Final disposal modes include: · sale as usable chemicals · on-site treatment for hazard reduction and/or volume reduction · crushing and disposal of empty drums · disposal of full and partially full drums, with or without over-packing Table 4 shows the type of profiling necessary for each type of situation that might be required. Parallel testing of the contents of the tanks on the site will also be needed. Based on the profiling, suitable disposal modes will be finalized and submitted for approval. 29 emcon Associates Potential Disposal Mode Salvage for re-sale. On-site treatment for hazard and volume reduction Non-hazardous materials - [potentially designated wastes] Unknown [potentially hazardous wastes requiring Class I disposal].

Use the HAZCAT screening program. 30 emcon Rssociates 2.5.5 Surface Water Run-off As indicated elsewhere, some uncontrolled storm water run-off occurs at this site. If a temporary mitigation plan is approved (submitted 12/26/85) and implemented, this problem will be controlled at the time the RI is implemented. The sampling planned under Section 2.5.1 above, should detect any off-site contamination that might have occurred from historic discharges. 2.5.6 Air Quality As part of the RI an assessment of the possibility of contam- inant migration via the air pathway will be made. This assessment will address both current site conditions and planned or possible remedial activities. The assessment will address the followin items: . Potential for release of noxious fumes from either damaged drums, from chemical transfer operations and on- site treatment operations. . Potential for release of potentially contaminated dust from wind corrosion and uncontrolled excavations and/or soils handling. Assessment will include nature and quantity of potential toxic air releases, as well as identification of populations at risk. 31 emcon Associates Based on the assessment, an air sampling monitoring plan will be developed for implementation in the RAP. 2.6 Schedule The RI is expected to take about four months (see attached Schedule, Fig u re 8). Pacing items for this program are: A. Preliminary Data Gathering 4 weeks B. Field Investigation Including drum profiling 6 weeks c. Laboratory Analysis 3 weeks D. Final Data Reduction and Report 3 weeks The schedule assumes that the assumptions outlined in the program are, in fact, verified in practice. 32 emcon Rssociates Figure 8 .EDIAl INVESTIGATION SCHEelE B.C.

Soluble in hot or cold water and can be rinsed off with water leaving a streak-free surface. Safe to use because it is a non-explosive water solution. Non-corrosive to metal and concrete surfaces. Economical to use. How to use B C Chemical Three-Way Degreaser For medium to heavy deposits of oil and grime, dilute all purpose cleaner with 3 to 10 parts of water. For very heavy deposits of oil, grease or dirt, mix concentrate with 3 to 1 0 parts of kerosene or diesel oil. Application Methods B C Chemical Three-Way Degreaser may be applied by wiping, brushing or spraying on the soiled surfaces. The product may also be used in dip tanks or circulated through equipment to remove oily deposits. Vertical surfaces may be cleaned by mixing 4 parts of B C Chemical Three-Way Degreaser with 4 parts of kerosene and 1 part of water. This mixture clings to vertical surfaces until rinsed with water. Handling B C Chemical Three-Way Degreaser is an alkaline solution and contains detergents. Care should be taken to avoid splashing product in the eyes. In case of eye contact, flush eyes with plenty of water. Packaging 5 gallons and 55 gallon drums Page 1 3 e e . CTS-1 CLEANER In the B. C. Chemical line of cleaner products I this high-alkaline detergent is designed for use in pressure spray or soak type bottle washers. Well adaptable for heavy-duty cleaning of product lines, pasteurizers I mixers, cookers and other processing equipment. CTS-1 Cleaner is a blend of alkalies, organic chelates, sequestrants, wetting agents and other ingredients. These combine to provide a full range of important advantages I such as: A complete bottle washing material. It's very effective in automatic bottle washing machines of all types, including high pressure spray machines. A thorough cleaning agent for spray washing of reusable plastic milk containers. The high alkaline content provides germicidal protection. CTS-1 provides lubricity to reduce friction and wear in bottle washers. Sequestrants prevent the deposition of scale on bottles and washers. Organic chelates aid in the control of aluminate scale, caused by dissolved aluminum foil labels. The best in cleaning results from high rinsability. In food plants, CTS-1 is a heavy-duty cleaner for product pipelines, juice pasteurizers, vegetable cookers, and other stainless steel processing equipment. How and where to use CTS-1 Cleaner Bottle Washing: Concentration of CTS-1 depends on the caustic requirements of regulatory bodies in the locality. 1 oz. per 1 gal. of CTS-1 equals .71 % cuastic by weight; or .7 oz./gal. equals 1/2% caustic by weight. When a code requires 3% caustic, this can be met by using a solution of CTS-1 at 4-1/4 ounces per gallon. Food Processing Equipment: a 2 to 4 oz./gal. solution at 1600 - 1800F, will handle most jobs. Plants with central alkali system: for all phases of cleaning operations, the central reservoir should contain 4-1/4 oz./gal. to handle bottle washing, heavy-duty cleaning and circulation cleaning requirements. CTS-1 is especially useful in breweries, bottling plants, dairies and food canneries. NOTE: Uke any alkaline material, CTS-1 should be added slowly to cold water while stirring - never to hot water either for original makeup or for upkeep. The usual precautions for handling alkaline materials and solutions should be observed. P~m> 1 4 e e AST-1 Cleaning Compound AST-1 is a formulated product that quickly and easily removes soils and stains that ordinary cleaners do not. AST-1 is non-toxic, will not cause burns on the skin; has no irritating fumes; is non-corrosive; safe on all plastics and paints; and on electrical insulation. Will not injure acrylic paint or other paints used on equipment, machines or autos. COMPOSITION Water based solution of alkaline ingredients, biodegradable surface, active agents, and emulsifiers. Is non-flammable and has to flash pOint up to and including its boiling point. AUTO AND TRUCK WASHING Pre-rinse with water. Dilute 1 cup AST-1 per gallon of water. Apply by spray and brush surface, rinse with water. This will not cause any harm to car finish. Leaves a bright and well kept appearance; STEAM CLEANING Dilute up to 20 to 1 in solution tank, no caustic, no odor. Safe on all types of metal. Aluminum and stainless steel especially. Provides spray wetting and penetrating action.

Typical Properties: Appearance Density, Lb/Gal. Sulfite % pH - 50% Solution Clear Ught Yellow Uquid 10.8 55 4.5 Suggested Uses: OS-1 00 may be substituted directly for catalyzed sodium sulfite as an oxygen scavenger. It is a stable solution and being a liquid, there are no dissolving and plugging problems. Use of 05-1 00 in drilling fluids and other water treatment uses allows protection from Oxygen corrosion of drill pipe, pumps and other metals in contact with the media. OS-1 00 should be added continuously directly at the pump suction utilizing a chemical injection pump. Theoretical treating ratio is slightly less than 9 parts of 05-100 per 1 part of oxygen. Pumping rate is dependent upon the oxygen concentration present. A minimum of 100 ppm excess sulfite is recommended. In drilling fluids, the base line corrosion rate may be established by running drill pipe corrosion rings in the drill string prior to commencing treatment. The coupons should be run in the drill collar cross-over sub, and the kelly saver sub. If only one coupon is to be run, it should be placed in the drill collar crossover sub. Rings should be run a minimum of 50 hours (100 hours is desired). Page 1 9 e e BC MICROBIOCIDES 5 gallons 55 gallons B.C. Microbiocide 1000 B.C. Microbiocide 2000 B.C. Microbiocides, available as B.C. 1000, a 25-per cent aqueous solution of glutaral- dehyde, and B.C. 2000, a 50-per cent aqueous solution of glutaraldehyde, are useful as preservatives and in formulating broad spectrum industrial biocides. B.C. Microbiocides have many important features including: · EP A Registration ' · Effectiveness against a broad spectrum of microorganisms · Aqueous solutions which are easily and uniformly diluted and mixed · Ability to be easily neutralized for disposal · Effectiveness against aerobic and anaerobic organisms .Compatible with anionic, nonionic, cationic surfactants · Do not contain or release formaldehyde · Lower vapor pressure than formaldehyde · Diluted product easily analyzed by gas chromatography · Not affected by the presence of hard water STORAGE AND HANDLING OF B.C. MICRO BlOC IDES OIL WELL MICROBIOCIDE B.C. Microbiocide 1000 is an aqueous solution of Glutaraldehyde, at 25% (by weight) concentration. It is slightly corrosive to common materials of construction, such as steel, aluminum, and galvanized iron; the corrosion rates are low (equipment would not be severly damaged) but contamination of the product will result if contact is prolonged. Materials which have been tested and found to be suitable are stainless steel, certain fiberglass-reinforced plastics I and polypropylene or polyethylene. Types 304 or 316 stainless steel are suitable. Of the plastics tested, a polyester ("Atlac" 382) and a vinyl ester ("Derakane" 470) were resistant, but an epoxy showed some adverse effect after prolonged exposure to Glutaraldehyde. Uned steel containers are not recommended because iron contamination can result, due to pinholes in the coating. NOTE: Storage tanks, lines, pumps, valves I etc" must not be made of iron or steel.· Even trace iron contamination (one ppm or less) can have an adverse effect on the long-term stability of the product. The 25% solution freezes at about -10°C (14°F). Thus, if outside storage is planned, heated and insulated facilities will usually be required. However, the storage stability of Glutaraldehyde is very dependent on storage temperature and storage at temperatures below 100°F is recommended. Preferred locations for a storage tank might be either indoors or underground; drums could be stored in a warehouse or, during hot weather, in a shaded storage area where they are not directly exposed to the sun. If B.C. Microbiocide 1000 is to be heated, warm water is the preferred heating medium, in order to insure that the product will not be exposed to high temperatures. It is suggested that water temperatures should not exceed about 40-50oC (100-1 20°F) and temperature controls could be set so that the average temperature of the stored liquid is only about 20°C. This should insure a reasonably long storage life for the product. Piping and valves can be of polypropylene or polyethylene or stainless steel. A stainless steel centrifugal pump is suitable for transfer service. Asbestos can be used for gaskets and packing. NOTE: If B.C. Microbiocide is to be diluted, use only distilled/deionized water that is low in iron, calcium, and magnesium content.

AMAZING 1 gallon 5 gallons ECOLOGICALLY SAFE: The ingredients in B.C. Amazing products are bio-degradable - they will break down into natural components without harming the environment. There are no phosphates, enzymes, or other chemical ingredients known to cause pollution, in any B.C. Amazing product. ECONOM'CAL: B.C. Amazing products are concentrated. That means you use less - a little goes a long way. There are no "fillers" that serve only to bulk up a product and make it look like you are getting more than you are. EFFECTIVE: There are no better products of their kind on the market than B.C. Amazing products. Because they are different, because they do not contain some of the harmful ingredients many people are used to, when they clean their stoves with B.C. Amazing and find there are no dangerous fumes and no skin irritation. The effectiveness of products as good as B.C. Amazing can be unexpected and surprising. When the results are so far superior to most other products, it takes some getting used to. So suggest to every customer that directions be followed carefully, rather than using B.V. Amazing products "the way they've used that kind of product before!" VERSA TIUTY vs OVERKILL: Although we use the term "all-purpose cleaner" on the label of B.C. Amazing, since that has become more or less the generic term for the type of cleaner it represents, there really is no such thing as an "all-purpose" cleaner. So-called all-purpose products tend toward "overkill". They cater to man's search for the easiest way, rather than the best way. But no liquid cleaner designed to be used for scrubbing floors can be made powerful enough to remove stubborn stains, with being too powerful for gentler tasks. That's why B.C. Amazing products have been carefully formulated to provide safe I effective, and appropriate results for the task to be done according to how they are used. The versatility of B.C. Amazing products lets YOU decide how strong a cleaner YOU need for each job. . The label on B.C. Amazing describes this product as "a modern, soap less product made from a balanced formula of organic ingredients, completely free of skin and eye irritants". Let's look at each term in the name of this remarkable personal cleaner and see why we can make the claims we do for it: SOAPLESS: There are no alkalies, no phosphates, no soda ash, no artificial chemicals I or other harsh, irritating or polluting ingredients in B.C. Amazing. It will leave behind no soap scum or other residual waste. It rinses away cleanly and completely without drying the skin or leaving residues or washed surfaces. ORGANIC: The ingredients in B.C. Amazing are organic, that is, composed of the same types of carbon molecules that make up natural living matter. Thus, they are not only mild, but also biodegradable - capable of breaking down and returning to the earth, without endangering any living thing. CONCENTRATE: A little bit of B.C. Amazing goes a long way. That's why we offer a mixing bottle to go with it. All directions on the label are for B.C. Amazing diluted half and half with water - then measured in teaspoonfuls! That's real.concentrated action - and real economy for any "personal touch" cleaning job! ' -- e IMPORTANT: To prepare B.C. Amazing, fill a mixing bottle half way with water first· then add the Concentrate; stir or mix gently. ' ' TO DEMONSTRATE B.C. AMAZING: Always use B.C. Amazing according to directions, in a No. 501 Jiffy Dispenser with No. 502 Flip-top on the 16 oz. size. ECONOMY: Point out that even after dilution I only a very small amount of B.C. Amazing is needed for most ordinary jobs. GENTLENESS: Place a drop of B.C. Amazing from the mixing bottle into the hand of your prospect. Ask her to rub it in as she would a hand lotion. As she does, explain that B.C. Amazing is gentle enough to use in bathing an infant, and that in addition to cleaning, it actually acts much like a hand lotion in moisturing and conditioning the skin. Rinse the B.C. Amazing off with a damp washcloth or under a tap. NON-FLAMMABILITY: Remove the cap from a bottle of B.C. Amazing and wave a match back and forth over the opening. Point out that the fumes do not ignite. Next, extinguish the match by dropping a bit of B.C. Amazing onto the flame. (A wooden match provides a better demonstration than a paper match.) EFFECTIVENESS: Mark the back of your hand with lipstick and with a ball point pen, then massage in a dab of B.C. Amazing. Point out how the two difficult-to-remove blots immediately begin to be lifted from the skin by the B.C. Amazing handkerchief, then. . . . . . show the handkerchief stained with the lipstick and ink to your prospect. Rub the stain in for better effect. Explaining that the dab of B.C. Amazing you cleaned your hand with is still enough to clean the handkerchief I dip the handkerchief under a faucet, squeeze it clean, and display the spotless handkerchief to your prospect. Point out that B.C. Amazing is harmless to fine fabrics. Smear a steak of shoe polish, paint or grease across your palm (if you want to let this dry, you can demonstrate the match test or ask the prospect to feel B.C. Amazing for herself at this point). Point out that this technique provides excellent protection for the hands while doing a job of painting, repairing greasy machinery, gardening, etc. Finally, rinse your hands in a bowl of water or under a faucet and show how the "invisible gloves" have helped protect your hands. AUTO WASHING: Mix 2 capfuls of B.C. Amazing to a bucket of water. To remove tar from any auto finish, use the Jiffy Sprayer with B.C. Amazing, medium or strong solution, then wash with B.C. Amazing to avoid stripping wax from the finish. SUGGESTED DEMONSTRATION AIDS: Jiffy Dispenser with Pump; bowl of water; damp washcloth; handkerchief; lipstick; etc. You'll want to change or add demonstrations as you gain experience, of course - but always practice before you use them on a prospect. 27 e e BC P. W. 101 PARAFFIN DISPERSANT 5 gallons 55 gallons BC P.W. 101 Paraffin Dispersant BC P.W. 101, an effective water-dispersible paraffin-removal additive, is a high-flash, low-odor hydrocarbon solvent-d!spers~nt. This bl~nd helps solubili~e and disperse paraffin and asphaltic deposits. A water-external dIspersIon made wIth BC P .W. 101 IS an excellent substitute for hot-oil treatments, especially where oil spills and contamination are critical. Most paraffin dispersants do not function in aqueous systems as well as BC P.W. 101 nor do they have as effective paraffin-disolving properties. APPLICATIONS Wellbore and Tubing Cleanout BC P. W. 1 01 can be dispersed in water or acid to clean tubular goods of: paraffin and asphaltenes allowing resumption of normal production, paraffins, asphaltenes, and other hydrocarbons prior to other stimulation treatments. BC P. W. 101 can also be used in aromatic solvents and/or mutual solvents to help water-wet solids as the heavy hydrocarbons are solubilized by the solvents. The proper concentration of BC P. W. 1 01 to be added to water for optimum cleaning depends primarily on the amount of paraffin present, the hardness of the deposit, the adhesiveness of the deposit, and the temperature at which the paraffin is deposited. A general recommendation is: Cold Water (below 75°F)- Use 10% by volume of BC P. W. 101 Warm Water (75 - 1 OOOF)- Use 5%by volume of BC P.W. 101 Hot Water (1 00 - 150°F) - Use 2% by volume of BC P.W. 101 Very Hot Water (150 - 200°F) - Use 1 % by volume of BC P.W. 101 To compute volume: Diameter of casing Standing fluid in casing Feet of perforation in casing CAUTION When used for tubing cleanout, the water temperature should never be hotter than the formation face because any paraffin that has melted in the treated water will re-deposit on the colder formation causing damage. Flow Line Cleanout , BC P. W. 101 can 'be dispersed in water to clean flow lines. The above treat rates apply to flow-line cleanout. However, the water should be heated to as high a temperature as practical for most efficient removal. If the flow line is long and/or cooled by water (offshore), it may be necessary to increase the concentration of BC P.W. 101 to 5%. BC P.W. 101 will work in cold water at higher concentrations. If the water starts off hot then cools, the BC P .W. 101 will keep the removed solids dispersed. NOTE If large amounts of paraffin are deposited it may be necessary to use several lower-temperature treatments so as not to remove too large an amount of paraffins at one time, thereby physically blocking system. MIXING PROCEDURES BC P. W. 1 01 can be added to any aqueous fluis and a uniform dispersion can be achieved with only a small amount of agitation. If left static, the dispersion of BC P.W. 101 in water is stable up to an hour. Reagitation prior to pumping the fluid is recommended. SOLUBILITY Soluble in hydrocarbons Dispersible in fresh water, salt water, acids ?A e e This product is available in bulk shipments and 55 gallon NR drums. Keep drum openings closed to prevent product contamination and evaporation. BC P .W. 101 contains no organic halides, heavy metals, or other substances known to be harmful to process equipment or refinery catalysts. No special storage and handling precaution is required. Avoid prolonged and repeated skin contact. In case of contact with skin or eyes, flush exposed area with water. PROCEDURE Batch feed BC P.W. 101 per general recommendation at point liB". Let it sit for approximately 24 hours. Be sure BC P.W. 101 is completely mixed with fluid in well. Put well back on the line. BC P.W., 1 01 will perform an effective cleaning function throughout the entire system including all flow lines and valves. To eliminate future paraffin buildup, a daily maintenance program should be followed. Inject at point "A" 2 quarts of BC P.W. 101 every 24 hours per 100 barrels of produced oil. The simple and inexpensive procedures described above will virtually eliminate costly down time due to paraffin cake buildup. 29 e e _..~...-...' .--.- .---- .

Submittal of Final RI Report · e February 17, 1984 APPENDIX C GROUND-WATER SAMPLING PROTOCOL FOR VOLATILE AND SEMI-VOLATILE ORGANICS PROTOCOL INTENT This ground-water sampl ing protocol is prepared by EMCON Associates to provide a consistent and reproducible procedure for obtaining samples of ground water from monitoring and production wells. This protocol is intended to re.duce potenti al sources and magnitude of contami nati on to ground-water samples and is primarily applicable to ground-water samples suspected of containing volatile and semi-volatile (BNA) organic com- pounds. With proper containers and preservation techniques, this proto- col can be extended to cover other classes of chemicals in ground water. Reference is made in thi s protocol to Methods 624 and 625 of the U.S. Environmental Protection Agency (U.S. EPA) as published in Methods for Organic Chemical Analysis of Municipal and Industrial Wastewater, U.S. EPA publication EPA-600/4-82-057, July 1982, Cincinnati, Ohio. Specific reference is made to paragraphs 3.2, 5.1, 8.6, 9.1, 9.2, 9.3 and 9.4 of Method 624 and 5.1, 8.6, 9.1, 9.2 and 9.3 of Method 625. WELL SAMPLING SEQUENCE Where more than one well within a specific well field or site is to be sampled, the sampling sequence will begin with the well having the least suspected contamination. Successive samples will be obtained from wells of increasing suspected contamination. If the relative degree of suspected contamination at each well cannot be reasonably assumed, sampling will proceed from the perimeter of the site towards the center of the site. The sampling sequence will be arranged such that well s are sampl ed in order of i ncreasi ng proximity to the suspected source of contamination. EQUIPMENT CLEANING Sample bottles, bottle caps, and septa for use in sampling for volatile organi cs will be thoroughly washed wi th detergent, ri nsed extensively with tap water, and then rinsed again with high purity deionized water. After washing and rinsing, sample bottles and components will be dried at a temperature of 150°C overnight. Sample bottles, bottle caps, and septums will be protected from all forms of solvent contact between the time of drying and actual usage at the sample site. Sample bottles, bottle caps and cap liners for use in sampling for semi-volatile organ- i cs (BNA) wi 11 be thorough 1 y washed with detergent, ri nsed with tap water, rinsed with acetone or methylene chloride, and dried before use. · - Duri ng the purgi ng operation, purged water wi 11 be moni tored for tem- perature, pH, or conductivity as a function of time or volume. All records of the above data will be kept in a water-proof field notebook in the following format: WELL # TOTAL DEPTH DATE PROJ. # TOC RECORD 2" PUMP # DEPTH TO WATER ~~c TOC GL = CALC: EVAC. VOL. 4" PUMP # BAIL/IN PLACE PUMP ACT. EV AC. VOL. COMMENTS: SAMPLES: After the calculated purge volume has been removed, samples will be co 11 ected. With as 1 itt 1 e interruption in pumpi ng rates as poss i b 1 e, the pump effl uent is di rected into appropri ate contai ners. For the volatile organics, care must be taken not to allow the force of the sample stream to introduce air bubbles into the sample. These bottles must be filled completely such that no air is present in the bottle. Invert the bottle after capping and tap to see that no air bubbles are present. Appropriate containers for volatile organics are glass bottles of at least 40 milliliters in size fitted with teflon-faced silicon septa. Appropriate containers for semi-volatiles (BNA) are one gallon amber bottles fitted with teflon-lined seals. All samples will be collected in duplicate. Field blanks made with organic-free water will be carried into the field and delivered with samples to the laboratory. All sampling containers will be labeled with the following information upon sampling and then immediately placed on ice: t;;;) Job No ~Dlte ~m~<?n Sampler SDurce Pnurvetlon Sample No Samples will remain on ice until delivered to the laboratory. Also at the time of sampling, the sample will be logged on a chain-of-custody form whi ch wi 11 accompany the sampl e to the 1 aboratory. One out of every 10 samples will be submitted to a laboratory other than the primary laboratory to confirm the accuracy of results. ~TA'TF nF.r~AIII=nRNIA . Fnvl,nn"",nt'" p'~nn Agl'n"v .

Becker Staff Engineer DATE: 2 November 1994 SIGNATURE: ~-J.~ SUBJECT: SITE ASSESSMENT, BC CHEMICAL, BAKERSFIELD, KERN COUNTY SITE BACKGROUND Between 1970 and 1985, BC Chemicals operated a custom chemical mixing facility and supply yard at the site. The company filed for bankruptcy in 1985 and vacated the property. Past operations have been identified as potential sources of contaminants. These operations include the disposal of washwater into an earthen sump, a regulated concrete-lined sump (Waste Discharge Requirements Order No. 80-129), and a large holding tank. Other potential sources of contaminants at the site include several hundred abandoned poorly,labeled drums that may have leaked. At least 20 polyurethane and steel chemical storage tanks were also left at the subject property. Several soil investigations and cleanup operations have been conducted at the site since 1985. In 1988, the abandoned drums were characterized, removed ,and disposed of. A total field magnetics and ground-penetrating radar survey was conducted in 1991 to identify potential buried tanks. Several site assessments included the collection of soil samples from drum storage, acid storage, stained soil, and water ponding areas. Samples were also collected from soil piles left from grading operations of an earlier cleanup. Underlying soils consist mainly of clays, silts, and sands to 80 feet below ground surface. Depth to ground water is approximately 200 feet. Based on site conditions, the expected attenuation factor should be greater than 100, but less than 1000. The RESNA Company submitted a 5 February 1993 report that details the results of further site assessment and a proposed closure plan. The following is a summary of site conditions and a review of the proposed closure plan. AREAS WITH POTENTIAL THREAT TO WATER QUALITY EARTHEN SUMP AREA Although the exact location of the earthen sump is not known, information in the file indicates that it most likely was located in the southwestern corner of site. Based on areas of ponded water and drum storage, three borings and 8 surface soil samples were collected within the suspc.."Cted area of the earthen sump. One SUrf.1ce sample (5-5, Figure 1 - ICF Kaiser) contained Endrin ,Endosulfan n,phenanthrene, fluoranthene, pyrene, and chrysene. Samples collected in Boring 101 (BIOI) ~ Reviewed By. t;11\J21 ! e e BC Chemical Kern County -2- contained contaminants at 10 feet bgs, but were not detected in deeper samples. Elevated levels (693 ppm) of total chromium were detected in one surface sample (S-2), but were not detected in deeper soil samples. Evaluation: Sampling indicates the extent of contaminants in the soil profile is less than IS feet at this location. Contaminants do not appear to have migrated into ground water. LOADING AREA Boring BI12 was installed and four surface samples were. collected in the area. The contaminants phenanathrene, fluoranthene, pyrenet chrysene, 4,4-DDD, Endrin, and Endosulfan IT were detected in some of the surface samples. These contaminants and elevated levels of metals were not detected in deeper boring soil samples. Volatile organics compounds (VOCs) were detected in soil samples collected at 5, 20 , and 40 feet bgs. Evaluation: The vertical extent of VOCs contaminants has yet to be defined at this location. ACID CONTAINMENT TANK AREA One boring (BI04) was drilled in the center of the acid tank area and advanced to approximately 65 feet until field vapor readings indicated background levels. Soil samples were collected at 5,20,40, and 65 feet. Three surface soil samples were also collected in the area. Results from the boring indicate that volatile organics are present in soils at depths of at least 40 feet( 65 foot sample was not analyzed for VOCs). The surface soil samples contained elevated levels of chromium (1000 PPM), Endrin (4.5 ppm), and DDT (5.7 ppm). Evaluation: The vertical extent of VOCs in the soil profile has not been defined. The levels of pesticides detected in the surface soils exceed the TILCs listed in Title 22, CCR, § 66261.24. CONCRETE SUMP The concrete lined sump was regulated as a temporary storage area for wash water that was to be removed to a Class I disposal site. Results of one soil sample (S-12) indicated elevated levels of chromium (261 ppm),but no semi-volatile or pesticides were detected. One boring (B105) was constructed approximately 50 feet west of the sump. Elevated chromium levels (1460 ppm) were detected at the surface near the boring, but concentrations were at background at approximately 20 feet bgs. e e BC Chemical Kern County -3- Evaluation: The samples collected near the concrete sump do provide some area information ,but do not provide information necessary to evaluate whether or not past operation of the sump has impacted ground water. CLEANUP/CLOSURE OF SITE SOILS Contaminants exist at different concentrations at various locations on the site. The discharger has proposed to close the site by paving all the areas with asphalt. EVALUATION: The proposal could be appropriate provided: 1. Hazardous concentrations of contaminants are excavated and transported to an appropriate disposal site. 2. The capping is constructed in accordance with Title 23, CCR, Section 2510 et seq., (Chapter 15) requirements and regulated under Waste Discharge Requirements. SUMMARY AND CONCLUSIONS I have reviewed the information in the file and conclude the following: 1. Since the vertical extent of VOCs in soils has not been defined in the Acid Containment and Loading areas, it is not possible to conclude whether or not ground water has been impacted by past operations at these locations. 2.
