Cutting oil is used to lubricate and cool the saw blades used for the process. The oil is recycled and recirculated throughout the process. Oil coating remaining on the pipe walls is removed by steam cleaning. In past practices, some of the wash residues were discharged in an unlined drainage sump situated in the rear of the facility. The manufacturing facility was constructed some 20 years ago and purchased by the present owners in 1970. Analytical testing performed by the B.C. Laboratories in response to the request of the Kern County Department of Health indicates the presence of lead and hydrocarbon in the near-surface of the pond bottom. As assessment of the potential for soil and groundwater contamination resulting from liquid waste disposal has been requested by Kern County. This work plan addresses soil contamination only. Dr. Kenneth D. Schmidt, Groundwater Quality Consultant in Fresno, will address groundwater quality aspects in a separate report. A Vicinity Map derived from a recent aerial photograph of the area is included in Figure 1. BSK Page 2 WORK PLAN The Work Plan presented herein is designed to provide an assessment of the potential for soil and groundwater contamination resulting from the discharge of liquid waste 'into an unlined drainage pond and to define the general extent of contamination. Hsdrdgeologic Settin9 The Valley Perforating Company facility overlies the Kern River Alluvial Fan. The sediments consist mainly of a younger alluvium of unconsolidated sand, gravel, silt and some clay typical of recent channel deposits. Groundwater at the site is first encountered at a depth of 19 feet below existing ground surface (see Boring Log B1, Figure 3). This upper body of water is identified as a perched layer likely resulting from recharge activities on the Kern River southeast of the site and, to a lesser extent, irrigation water transport in the Calloway Canal to the north of the site. The water table, as indicated by maps prepared by the Kern Water Agency Water Supply Report (1985), is at a depth of approximately 70 feet. In the immediate area of the site the water table grad'ient generally falls rapidly to the southeast. Soil Conditions A preliminary boring drilled in the vicinity of the pond (see Site Plan, Figure 2) indicates a thick and nearly continuous sequence of firm to moderately loose sandy soils with occasional silt lenses. The uppermost 13 feet contain significant amounts of silt. Below 13 feet, and to the maximum exploration depth of 30 feet, the soils grade to moderately clean sand with some gravel and silt lenses. As indicated earlier, water was encountered at a depth of 19 feet. Based on this preliminary data, the zone of least permeability overlying perched water, appears to be between depths of 7 to 13 feet. BSK Ya rd ~ 20' Grid ,] Typical / i.

The thinner contains mainly parafin-based solvent with minimal aromatics stabilizer. Soluble and cutting oils contain biodegradable soaps, oils and glycol, mineral oils and small amounts of chlorinated parafin. Material information bulletins for the thinner and chemical compositions for the soluble oils and cutting oils are shown on pages 6 through 8. Analytical testing was peformed by the B.C. Laboratories on soils extracts for specimens obtained in the sump near-surface and at shallow depths below the base of the sump. The tests were performed over the period of January through June 1985. More recently, lead content determinations were also made on soil and gravel stockpiles within the sump area. Test data is shown in Figures 4 through 9. The tests include metal analyses, base-neutrals, acids and purgeable priority pollutants and lead content determinations using both TTLC and STLC extraction procedures, in accordance with the California Assessment Manual. Constituents of significance as regards soil contamination include the following: - Lead - Hydrocarbons Both TTLC and STLC concentrations indicate the presence of lead ~ in the sump near-surface in concentrations deemed haz~_~ar~ The concentration of hydrocarbons in soils also exceeds the Kern County Action Level of 1000 ppm by a factor of 10. A~n levels for lead in soils are 1000 ppm and 5 ppm for the TTLC and STLC extraction methods, respectively. Contaminant Migration in Soils Contaminants present in the soils at the bottom of the sump were transported by runoff from surface wash water and rain. The contaminants were removed in the greater part by the near-surface soils. The removal process for inorganic and organic constituents and the mobility of these elements in soils are influenced by numerous physical, chemical and biochemical processes. Soil characteristics of primary influence on the processes include the following: Texture Cation Exchange Capacity pH Oxygen Content Organic Content BSK Page 4 Soil particle size, distribution and grading (texture) and the corresponding available pore space have major influence on permeability. With the more impervious clay and silt mixtures, the slow rate of water passage through the soil mass allows greater contact time and enhancement of the various removal procedures. Cation Exchange Capacity (CEC) refers to the negative charge present on soil particles. Except for arsenic, metals are positively charged, and this includes lead. Soils with high CEC, therefore, have the ability to detain the larger quantities of positively charged ions (contaminants) from liquid waste. The ion exchange reaction between positively charged ions (cations) and negatively charged soil particles delays migration and allows increased contact time for the various processes which attenuate migration of ions. These processes include the physical, chemical and biochemical activities described earlier which more permanently inhibit ion migration or mobility. High CEC soils are the silt and clay mixtures. Ion migration in soils is significantly influenced by pH and pH changes. In well buffered calcareous soils (soils with calcium carbonate and high pH), most heavy metals, including arsenic, will form relatively insoluble precipitates resistant to leaching. Conversely, in acid soils (low pH) or poorly buffered soils which become acidified due to acidic leachate, the precipitates will not form or previous precipitated ions may dissolve and become mobile and available for leaching. Sandy soils with little or no calcareous materials can be easily acidified by leaching or contact with acidifying materials and, therefore, most vulnerable to the effects of pH changes. Acidifying materials include the nitrogenous fertilizers and decomposing organic wastes which release organic acids. Soils with a pH greater than 7 are generally effective in controlling metal migration. Oxygen content in soils affects the migration of metals in soils. When micro organisms are present in significant quantity, oxygen influences the type of organisms that will thrive and their biochemical reaction which will create organic compounds and the release of mineral elements. Aerobic (oxidizing) conditions favor attenuation of contaminants while anaerobic (reducing) conditions accelerate migration of contaminants. Water logging in low permeability soils or under sump storage conditions would create temporary anaerobic conditions and contaminant migration. Minimal runoff which soaks into sandy soils would create opposite conditions BSK Page 5 particulary with the frequent wetting and drying of intermittent runoff applications. Soil organic.content has a decelerating influence on contaminent mobility. Organic matter increases cation exchange capacity and favors the Detention/Retention mechanics of metals. Moreover, insoluble precipitates are formed through the biochemical processing of soil micro organisms and metals. In the presence of hmmic acids (acidic soils) the formation of highly mobile chelated metals bound into organic complexes can occur. In the case of the soils underlying the sump, the materials are generally coarse textured, highly buffered, of low to moderate CEC, inorganic and mostly present under aerobic conditions. Lead mobility in the soil column is expected to be low to very low and within a depth of a few feet. The presence of hydrocarbons in concentrations in excess of the 1000 ppm action level remains undetermined at this time. Attenuation of hydrocarbons with increased depth is expected to be moderately rapid.

J~3. ~glin ~ Page 9 Field Investigation The field investigation would consist of drilling and obtaining intact samples of soils from various locations and depths for the purpose of determinating lead and total hydrocarbon contents. Migration and deposition of lead and hydrocarbons from liquid waste to soil solids has likely occured vertically beneath the pond and laterally away from the pond. Figure 2 illustrates the prop6sed pattern of boring locations and sampling points. Two types of exploratory and sampling holes are proposed: Borings, (B2, B3) Sampling Holes, (A through I) The borings would be drilled at the bottom of the pond and would be extended to perched groundwater at a depth of approximately 10 feet below pond bottom. Detailed soil classification, as described in the "Drilling and Sampling" section of this Work Plan, would be provided. Intact soil specimens in each of the two borings would be obtained at the following depths below pond bottom surface: 0 to 1/2 foot i to 1-1/2 feet 2 to 2-1/2 feet 3 to 3-1/2 feet 4 to 4-1/2 feet 6 to 6-1/2 feet 8 to 8-1/2 feet 10 to 10-1/2 feet Sample preparation, documentation and preservation would be carried out in accordance with the procedures detailed in the "Drilling and Sampling" s'ection. The sampling holes would serve to obtain intact soil specimens for the assessment of the lateral migration of contaminants from the pond. Sampling of soils above the elevation of the high water mark in the pond (3 feet ± below surface) would ~ccordingly not be performed. Moreover, because of the sandy native soils, the saturation line for liquids percolating from the pond is expected to fall rapidly away from the pond perimeter. Sampling depths accordingly would be as follows: BSK Page 10 Sampling Holes A,B,C,D: 4 to 4-1/2 feet 5 to 5-1/2 feet 6 to 6-1/2 feet 8 to 8-1/2 feet 10 to 10-1/2 feet Sampling Holes E,F,G,H,I: 6 to 6-1/2 feet 8 to 8-1/2 feet 10 to 10-1/2 feet Borings and sampling holes would be drilled with an 8-inch Hollow Stem Auger and backfilled in accordance with the procedures outlined in the "Drilling and Sampling" section. The removal of soil stockpiles in the pond and construction of a temporary access ramp to the pond bottom would be necessary for drill rig access to boring locations. Anal~%ical'Testing..Program The laboratory analytical testing program would consist of determining lead and total hydrocarbons content of soils specimens. The B.C. Laboratories in Bakersfield would provide all analytical testing for this study. Lead content determinations would be made using the Waste Extraction Test (WET) in accordance with the California Assessment Manual (CAM) procedure which requires a 48-hour extraction in a citrate or mildy acidic solution (pH=5). Total hydrocarbons content would be obtained by Standard Method 503E, 15th Edition. This method also corresponds to EPA Method 418.1, Petroleum Hydrocarbon, Total Recoverable, as modified to use gravimetric separation and funnel extraction. Intact soil specimens obtained at the locations and depths described in the Field Investigation section would be tested in the following two phases: BSK Page 11 Phase 1: Borings B2 and B3 - Samples from depths of 0 to 1/2, 1 to 1-1/2, 2 to 2-1/2 and 3 to 3-1/2 feet. Sampling Holes A,B,C,D - Samples from depths of 4 to 4-1/2, 5 to 5-1/2, 6 to 6-1/2 feet. Sampling Holes E,F,G,H,I - Samples from depths of 6 to 6-1/2 feet. Phase 2: Depending on the findings of the first phase, a portion or all of the remaining samples would be tested. Schedule Following Work Plan review and concurrence by the Kern County Department of Health, drilling would be initiated within one week of the notice to proceed by the owner. Approximately 3 days would be required to complete the field investigation and backfill drill holes and sampling holes. Depending on the results of the analytical tests, keeping in mind that the testing would be performed in phases, 4 to 6 weeks are anticipated to complete the laboratory analytical testing. The preparation of the Report of Findings and Assessment of Contamination would require an additional 2 weeks from the completion of the laboratory testing. In summary, 8 to 10 weeks from notice to proceed should be anticipated for the completion of the study. BSK Page 12 ENGINEERING TEAM The BSK Team would comprise Geotechnical Engineers, Geologists, Geohydrologists, and Chemists. Members of the team possess specialized experience in numerous facets of site exploration and contamination assessment, have intimate knowledge of subsurface conditions in the Bakersfield area, the subject site and of the Regional Hydrogeology and have worked with the State and Local Agency representatives responsible for the management and enforcement of waste discharge requirements. Basic field exploration and sampling services for the project would be carried out under the management of John Moore from the BSK-Bakersfield Offices and Laboratories. The actual work performed from this office, in addition to project management, would include the following: - Drilling, Exploration and Testing - Sampling and preservation of soil specimens. - Working relationship and.liaison with Kern County Department of Health Services.

Page 28 FIELD DOCUMENTATION AND CHAIN OF CUSTODY Information ~pertinent to field activities must be recorded in the following forms to provide proper documentation: Log Books Sample Tags or Gummed Label Photographs Chain-of-Custody Records The staff must keep detailed records of field activities. Records must be permanent, and written in waterproof ink. A Document Coordinator must be appointed for each project. The coordinator has the responsibility and custody of all records for the project. Log Book The field log book must consist of a bound book with consecutively numbered pages. The book must be used to enter information pertinent to field activities and must include the following: Date and time of entry and sample collection. Nature of work and purpose of sampling. Name of individual providing sampling. Name of waste generator. Type of waste and description of sample. Waste components, if known. Number, type and size of samples. Description of sampling point. Sample identification number. Field measurement data (pH, Conductivity, Temperature, etc.). Miscellaneous field observations and records of photographs. Log book entries must be initialled and dated by the individual. Photographs Photographs must be numbered and individually documented in the log book. Documentation should include the following: Date and time when photograph was taken. Photographer's signature of log book. Entry, if other than individual preparing the documentation and sampling. General direction faced in taking photograph and description of subject. Site location and description. Photograph sequence and roll designation numbers. BSI( Page 29 Photographs must preferably be taken with lenses capable of duplicating naked-eye perspective. High telephoto and wide-angle distortion should be avoided. Sample Tags and Labels Sample tags and labels must be filled out with waterproof ink. Labels must be affixed to the sample container. If tags are use~, the tag string must be secured to the sample container with a tape seal. The label must include the following information: Date and time'of collection. Sample number or identification. Label sequence number. Place of collection. Preservatives used, if any. CHAIN-OF-CUSTODY A chain of possession and custody of samples collected, transferred, stored, analyzed or destroyed must be maintained. The primary objective of the procedure is to create an accurate written record which traces the possession and handling of samples from sampling to its introduction as evidence in the event of litigation. A sample is in someone's custody if one of the following conditions are met: The sample is in the person's physical possession. The sample is in the person's view after being in his physical possession. The sample is in the person's physical possession and then locked-up so that it cannot be tampered with, or the sample is in a secured area, restricted to authorized personnel. Sample Collection, Handling and Identification The number of 'individuals involved in the collection, handling and documentation of samples should be kept to a minimum. Accordingly, the document coordinator should also be the Field Custodian who is charged with the responsibility of collecting, documenting and transporting samples to the point of shipment or to the laboratory. Sample Transfer The samples must be placed in transportation cases along with the Chain-of-Custody Record Forms, pertinent field records and analyses requests. The transportation case must be sealed or locked. Individual samples should be sealed at the cap in a way that provides detection of tampering. BSK Page 30 When samples are composited over a time period, unsealed samples can be transferred from one crew to the next. The transferring crew lists the samples and a member of the receiving crew signs the list. The receiving crew either transfers the samples to another crew or delivers them to a laboratory person, who signs for the samples. Tran~sfer of Custody and Shipment The person transferring the samples must sign and date the Chain-of-Custody Form (see attachment). Custody transfer must account for each sample or group of samples. Every person in the chain of possession must similarly follow the same documentation procedures. Receipts for mailed packages sent by common carrier must be retained as a part of the permanent chain-of-custody documentation.

The resultS of our field exploration and analytical testing program for soils indicate the following: Volatile organic compounds (EPA 601, EPA 602) were not detected in measurable concentrations in any of the 27 soil samples obtained from around and beneath the pond. The absence of organic compounds, in spite of earlier measurements of large hydrocarbon concentrations in pond-bottom soils, is likely the product of evaporation and migration of the volatile component of petroleum compounds, while the more stable mineral component which is mainly affected by slow biodegradation, remains in the soil structure and accounts for the hydrocarbon readings, discoloration and odoriferous character. Twenty-seven soil samples obtained from around and beneath the pond were tested for the presence of 17 trace metals. Only Arsenic, Chromium, Lead, Barium and Vanadium had concentrations of significance. These concentrations did not exceed the California Regional Water Quality Control Board (CRWQCB) "designated levels" and therefore, by CRWQCB definition, conform to water quality goals and are deemed to not have the potential for groundwater degradation.

Work scope, purposes and objectives of this report are based on a Work Plan prepared by BSK & Associates, dated August 28, 1985 (See Appendix "B"), and the various written and oral modifications and directives issued by the Kern County Health Department, as indicated in the correspondence contained in Appendix "C". Description of Facility and Operations Valley Perforating Company manufactures slotted and perforated well pipe for various oil industry usages. The facility was constructed some 20 years ago and was purchased by the present owners in 1970. New and used pipe is used for the stock material. Pipe cutting is performed with saw blades. The saw blades are cooled and lubricated with cutting oil. According to Valley Perforating Company, approximately 50 gallons per month of soluble oil were used during the period of March 1984 to May 1985. This has been replaced by Acculube. Additionally, approximately 500 to 750 gallons per month of Withrow 136 cuttin9 oil is used. The cutting oil is recycled and recirculated throughout the process. Oil coating remaining on the pipe walls, and any materials on the used stock material are removed by pressure steam cleaning. The wastewater from the steam cleaning process formerly drained across the property to an unlined dna image sump situated near the rear of the facility. BSa< & Associat~ Page 2 We have been informed by the owners that the wastewater generated by the steam cleaning operation is currently contained over concrete-lined aprons and diverted to a 12,000 gallon above ground tank for temporary storage and off-site disposal. The steam cleaner water travels over concrete to an 18 inch diameter, two foot deep pit. It is then pumped into the above ground tank. During the period of our field investigation, wastewater was not entering the unlined sump and the bottom of the sump was dry. Site Location and Description The site is located at the end of. Gulf Street, east of Pierce Road, and occupies approximately 3.5 acres of a rectangular piece of land which measures approximately 250 x 600 feet. The property is located in a commercial/industrial section of Bakersfield. The neighborhood also contains scattered housing. The propert'y to the east is currently vacant. Figure 1, Vicinity Map, shows the location of Valley Perforating Company, surrounding properties, and the unlined drainage sump. Much of the property is used for pipe storage; the manufacturing operation occupies about one-fifth of the property. The ground is generally level. The drainage sump measures approximately 30 x 50 feet, and is approximately eight feet deep. Soil scraped from the surrounding land has been placed in the southern end of the pond. At the time of the field exploration, the pond walls were discolored below the water line. The water line was approximately 2 feet below top of ground surface. BSK & Associates Page 3 SOIL CONDITIONS The dominant geologic feature controlling sedimentary deposition at the site is the Kern River. The site lies within the flood plain of the River, and sediments at the site comprise Younger Alluvium (see the Geologic Map, Plate 1). Our test holes drilled for this project show a sequence of interbedded sand, silty sand, sandy silt, and.silty clay. An approximate bedding sequence includes an eight to nine foot thick silty sand surface layer (probable flood-plain origin) which overlies an older, apparently partially eroded silt layer which likely tapers from a few inches at a location between Test Holes A and RH-1 to five feet or more in other locations. Although dominantly a sandy silt, the layer partially grades to a silty sand. The upper surface of the silt layer was encountered at a depth of approximately eight feet, and has apparently been eroded and removed in its northern portion, likely to an offsite location. The silt appears to have its origin as swamp and overflow land from the Kern River and may. correlate with a northward extension of Buena Vista/Kern Lake or shallow marshy tributary areas. The marshland appears to have been created as a backwater effect from the blockage of the northward flow of water by the Kern River Alluvial Fan. The lowest continuous layer encountered is a sand layer of (probable) significant thickness. The sand is similar to that exposed throughout this part of Kern County and may correlate with an areally extensive deposit of sands and gravels. Below the pond bottom area is an irregular sequence of soils which show a complex deposition/erosion pattern (see Figure 2 for a schematic cross-section of the subsurface soil conditions). The soils below the silt layer observed below the pond show a limited coherent layering pattern, and it is evident that these BSK & Associates · Page 4 extensive soil deposits have become locally eroded and removed. These fine-grained soils probably have little significance to the project, as their limited areal extent would provide little if any additional barrier to the subsurface flow of wastewater. An E-log for a well located approximately one mile south of the Site shows that the sand and gravel extends to a depth of approximately 140 feet and that weakly consolidated Pliocene continental deposits occur at a depth of approximately 200 feet. Consolidated or crystalline bedrock occurs at a great depth below the site. (Borings Logs B, B2, B3, A, B, C, D and RH1 are shown in Figures 4 through 11. A Test Hole Location Plan is shown in Figure 3.) GROUNDWATER CONDITIONS Groundwater was encountered at a depth of approximately 19 feet in Test Hole B-1 during our preliminary site characterization, in August 1985. Indication of groundwater were encountered at 17 feet in several of the test holes drilled during our February 1986 field investigation. This investigation was directed towards an appraisal of soil conditions and potential soil contamination in the vicinity of the drainage pond. Additional assessments regarding groundwater conditions are beyond the scope of this report.

Page 5 FIELD EXPLORATION Test Hole Drilling and Soil Sampling Field exploration included a preliminary site appraisal, test h'ole drilling, soil sampling, sample handling and packaging protocols, elevation surveys, test hole grouting, and site restoration. Our initial field work began with a preliminary field appraisal of site and soil conditions on August 24, 1985. Our preliminary appraisal included drilling a single test hole (Test Hole B-l) to a depth of 30 feet. Information obtained from our preliminary work was incorporated in our Work Plan issued on August 28, 1985. Additional field work began on January 2, 1986, with the drilling of an additional seven test holes at locations shown on the Test Hole Location Plan, Figure 3, and the Aerial Photograph of the site, Figure 1. The drilling was performed with a truck mounted Mobile B-50 drill rig using eight-inch hollow-stem auger. Drilling fluids and other additives to the drilling process were consequently unnecessary to advance the hole and obtain soil samples. The drill rig was thoroughly steam cleaned prior to entering the project site. The drill crew consisted of a driller and drillers helper. Field supervision was under the control of a geotechnical engineer and engineering geologist who provided field logs of borings, recording of field conditions, soil sample handling and preservation, and controlled the field equipment cleaning process. Prior to drilling at each location, the immediate area was cleared of foreign materials and obstructions to preclude foreign materials from entering the bore hole.

Drilling equipment was cleaned in an area on the site regularly used for steam cleaning of Valley Perforating equipment, and which had a provision for drainage to their wastewater collection system. Samples of soil were obtained at one to five foot intervals, depending on observations of soil conditions during the drilling process. Samples were collected intact, in an undisturbed condition in stainless steel liners. The samples were capped with teflon, then with a pressure fitted plastic cap and then sealed with an adhesive tape. Each of the samples Were labeled with an adhesive-backed label including boring designation, depth of sample, and initials of the individual preparing the sample. Prior to each sampling, the sampling equipment was cleaned with a detergent wash, followed by a distilled water rinse, followed by an acetone rinse, followed by a further distilled water rinse~. The samples were placed in an ice chest for the short storage time required for the field work. Upon completion of the daily field work, the samples collected were hand delivered to B.C. Laboratories, located two blocks from the site. The samples included requisite chain-of-custody protocols which included a description of the sample, sample location and depth, time, date, and name of individual performing the sampling work. The receiving laboratory signed the forms, indicating receipt of the samples. At no time were the samples out of the direct observation of the field personnel until final delivery to B.C. Laboratories. Two persons, Dr. Tso-Wang Lin, BSK & Associates Geotechnical Engineer, and John Kirk, BSK & Associates Engineering Geologist, were soley responsible for obtaining, preserving, handling, and delivering the samples and maintaining records of field work and sample documentation. Soil samples BSK & Associates.- Page. 7 were not composited or otherwise combined. Copies of chain-of-custody forms are attached to this report. Clari Binder and John Harris, with the County of Kern Health Department, were present January 2, 1986 to observe field activities. Health and Safety As indicated in our Work Plan, a Health and Safety Plan was established for work at this site. The plan included a preliminary assessment of materials which could be encountered during our field investigation. BSK & Associates employees had been provided with a medical evaluation prior to entering the site, and once again upon project completion, the purpose being to access an individuals exposure to hazardous materials at this site. BSK & Associates personnel working on the site used a combination of Level "C" and Level "D" protective clothing, including: Gloves: - Chemical protective neoprene Protective Clothing: - Tyvek, Saranek-coated, zippered overalls Footwear: - Disposable neoprene boots Respirators: - Half-mask air-purifying chemical cartridge respirator with an organic vapor cartridge and dust, fume and mist filters - Dust, fume and mist face masks BSK R, Page 8 LABORATORY ANALYTICAL'TESTING Test Methods: Laboratory testing was performed by the B C Laboratories, in Bakersfield, California.

BSK Page 11 ANALYTICAL DATA INTERPRETATION The analytical testing of soils requested by the State Department of Health Services (DOHS) and Kern County Health Department (KHD) in the letters of October 2, 1985 and October 22, 1985, respectively, consisted of the following programs: Complete Metal Scans Volatile Organics in Accordance with EPA Test Series 601 and 602 As indicated in the analytical testing section, the tests were conducted by the BC Laboratories in Bakersfield. Test data as submitted by the laboratory, are enclosed in Appendix "A". The following interpretation of data is made: Volatile Organics: All 27 samples tested for volatile organics of the EPA 601 and 602 series produced non-detectable concentrations. Detection limits of 0.50 parts per million (gm/gm) were used in the test. The absence of volatile organics is however contrasted by earlier measurements of significant total hydrocarbons (BC Laboratories, 12/11/84) in concentrations of 10,000 mg/kg in the near-surface of the sump bottom and the frequent odor and oily indication in the soils underlying the sump. An explanation of this occurrence is in the time-dependent volatilization and migration of volatile compounds in petroleum products contained in relatively shallow, non-saturated soils while the more stable mineral component, which is mainly affected by slow biodegradation, remains in the soil structure and imparts a visible and odoriferous character. Similar conditions have been observed in the case of an unlined sump used for the storage of waste oil (Refinery Services, 1985). In this instance the BSK Page 12 volatilization phase likely occurred in part as a result of open- atmosphere past usage of organic compounds. The absence of volatile compounds in the sump subsurface further suggests that present usage of products with volatile organics and disposal to the sump is not practiced. As indicated by Valley Perforating Company, soluble oil was used only during the period of March to May 1985. The soluble oil has been replaced with non-soluble A'cculube. Metals: Twenty-seven soil samples were tested for trace metals. The tests were performed on samples obtained from depth intervals of approximately 5, 10 and 15 feet below ground surface around the sump area (Sample Holes A, B, and C) and depths of 3, 5, 10, 12 and 16 feet below ground surface in the Sump Area. The tests were conducted in accordance with the California Assessment Manual (CAM) by a process of total digestion and determination of total concentration, (TTLC). Of the 17 metals tested by this method, only arsenic, chromium, lead, barium and vanadium produced TTLC concentrations slightly in excess of the CAM Soluble Threshold Limit Concentration (STLC). Other metals were below the STLC concentrations and therefore considered neither "Hazardous" nor "Designated" as defined by the California Regional Water Quality Control Board (CRWQB). These metal concentrations, therefore, are deemed to not have the potential for groundwater degradation. Comparisons of DHS and CRWQCB "Hazardous" and "Designated" levels for soil metal constituents, with the results of laboratory analyses, are presented for each of the 29 soil specimens in Tables I through 26. Comparisons against background concentrations for soil specimens obtained at similar depths, in a boring drilled at some 1500 feet away from the sump area, are also shown in the tables. These comparisons are summarized below and suggest that elevated levels of arsenic, chromium, lead, barium and vanadium exist beneath and around the sump area. Elevated metal concentrations in ratios of 3.4 to 1.56 are present beneath the sump. These ratios decrease to 2.3 to 1.6 in the area within 40 feet of the center of the sump. BSK ~, Associaies Page 13 Two composite samples of soils obtained by representatives of BC Laboratories from the surface of the pond bottom were tested at an earlier date (6/18/85) and reported TTLC and STLC values of 3680, 760 mg/kg and 250, 56.8 mg/kg, respectively. These tests were not duplicated in the sampling and analytical program. METAL CONCENTRATIONS IN SOILS BACKGROUND VS.

For the five metals with TTLC above STLC, a method developed by the California Regional Water Quality Control Board (CRWQCB) provides a means of determining BSK & Associates Page 16 whether these metals, based on TTLC, are in concentrations deemed to have the potential for groundwater degradation.~1}' ' Appendix 1V together with the Guidance Document provide derivative values for total metals "Designated levels" in a solid. These values are tabulated in Column (6) of Tables i through 26. For example, the total concentration of lead in soil for the "Designated l'evel" classification is 500 mg/kg. TTLC of lead below this value is deemed to not have the potential for degradation of groundwater. A comparison of Columns i and 6 indicates that all five of the metals; arsenic, chromium, lead, barium and vanadium, are present in the pond subsurface and immediate vicinity in concentrations well below "Designated levels", and would not therefore be considered to be of concern. Water Quality goals extractable concentrations are accordingly not exceeded in any of the tests for metal concentrations. .The derivation of total concentration "Designated levels" shown in Column 6 is obtained by applying several factors to the concentrations obtained by means of the Waste Extraction Test. (WET) shown in Column 5. These factors include the following: (1) Appendix IV, Guidance Document, California Regional Water Quality Central Board, Central Valley Region. "Waste Classification and Clean-up Level Determination", by Jon Marshack, November 21, 1985. BSK Page 17 A bioavailability multiplication factor of 100 for inorganic constituents An environmental attenuation multiplication factor of 100 (except for copper, zinc and cyanide which are assigned a value of 1000) based on constituent mobility in soils A division factor of 10 to convert mg/1 of extract to mg/kg of waste. In most cases, according to the factors described above, WET concentrations (Column 5) multiplied by 1000 provide the "Designated Level" concentrations in Column 6. In conclusion, except for the pond bottom uppermost two feet of soils and Soil stockpiles which by earlier tests indicated the presence of lead in hazardous level concentrations (in excess of TTLC and STLC), remaining soils beneath the site and sump do .not have metal concentrations in excess of the CRWQCB "Designated leve.ls", meet water quality goals, and by CRWQCB definition, are deemed to not have the potential for groundwater degradation.

This Item requires that certain additional organic chemical tests be performed on the soil samples. Enclosed is our proposal for the scope of services requested at this point in time for the characterization phase. Depending on the results of this phase of investigation, additional work could be required by State and County Agencies. The Kern County Agency has agreed however to initially limit the scope of work until test results can be obtained and evaluated. Should this Proposal meet with your approval, we would ask that you sign the enclosed agreement and return it to this office so that vie can schedule the field work.

Our response is keyed to the item numbers of your letter of October 22, 1985. ITEH I Background samples can be obtained. Sampling depths of 3, 5 and 10 feet from natural ground surface are proposed. Direct comparisons to the tests required for the Valley Perforating Site would be provided. Access and right-of-entry to private property may be a problem, however. Your assistance in this matter may be required. Perhaps this could be done on Kern County or City of Bakersfield public right-of-way. Another difficulty with the selection of site for background sampling is in finding an area unaffected by past oil-industry-related activities. Tile general vicinity of the Valley Perforating Company Site has a long history of industrial activity related to oil extraction and production.

This corresponds to a depth of approximately 10 feet below bottom of sump. In order to avoid the potential for introducing contaminants into groundwater during drilling and sampling operations, we strongly recommend that drilling penetration and sampling be stopped several feet above groundwater. In this instance, sampling depths of 2 and 7 feet .'below bottom of sump are recommended. Should the 7 foot samples indicate significant contamination, slant-drilling from the top of the natural ground surface to groundwater beneath the sump could be performed at a later stage. The latter approach does not eliminate contamination risks but reduces the potential to a lower risk level. In either case, the holes would be filled with a cement grout at completion of drilling and sampling. ITEM 3 The requirement for EPA Test Methods 601 and 602 and complete metal scan for all soil samples is a significant departure from previously discussed concerns of lead contamination. If the decision to include these tests is based on the data contained in the material information bulletin for "Schwebel Petroleum Company Incorporated Thinner 350", included in our Work Plan, reconsideration is recom'mended in 1.ight. of the owner's statement that such material is not used on the premises and that the bulletin was included in error (see letter of October 15, 19.85 attached). ITEM 4 The additional two test holes requested on the east side of the sump present a number of difficulties: The property owner, according to Mr. Reynolds, is not likely to cooperate in view of past dealings. The area contains high-pressure oil transmission lines and a risk exists in damage and significant disturbance to the flow of oil. Approval from the respective oil companies would also be required. In the best of circumstances, considerable delays will be experienced in obtaining the necessary approvals and coordinating the work. BSK Site Clean-up Valley Perforating Company Bakersfield, California Our Job 85238 October 29, 1985 Page 3 Our recommendation, for this phase of investigation, is to not drill on the east side for the following reasons: The site is relatively featureless. Soils within~ the upper 20 feet are uniform and consist mainly of silty sand and fine sand. The distance between borings from the east to west side of the sump is not likely to exceed 60 feet. Little difference in soil stratification is expected within this distance. Lateral spreading of liquid stored in the sump would have occurred uniformly in all directions. Conditions on the east side should accordingly be similiar to those on the west side. Findings for tests performed on the west side should provide an adequate representation of conditions on the east side. At the completion of work on the west side, a reassessment of the necessity for drilling on the east side can always be made at that time. This approach would eliminate excessive delays in the assessment of contamination and implementation of clean-up work. ITEM 5 Sample Holes E through I would be deleted at this stage of work. ITEM 6 Samples would be collected at the indicated depths of 5, 10, and 15 feet in Test Holes A, B, C, and D. ITEM 7 Teflon would.be used to provide the closure of sample ends~before capping. Acetone~would be used for equipment cleaning. ITEM ,8 Neoprene Safety Boots would be included in the site safety program. ITEM 9 The owner has been apprised of the requirements for subsequent studies for alternative corrective action and clean-up plan.

Relchard Mr. Jerry Reynolds Valley Perforating Co. 3201 Gulf Street Bakersfield, CA. 93308 Subject- BSK Work Plan for Site Clean up Dear Mr. Reynolds' This department has been asked to respond to the Work Plan presented to your company by BSK. That work Plan was recently submitted to the Regional Water Quality Contro! Board, (RWQCB) the Department of Health Services (DOHS), and this office for review. This letter is a combined effort of recommendations recieved from the DOHS and the RWQCB as well as this department's. You will be receiving a separate letter from the RWQCB which will'address that agency's concerns. You will be expected to incorporate those instructions with those you receive in this letter. The major areas of concern that this department and the DOHS has regarding your site cleanup work plan are as~follows· 1. A background sample should be taken from off site of the Valley Perforating;s property. Ground water in this area has been determined to be 19 feet as reported by the BSK drilling iog. Both samples from the sump should begin at 3 feet from the surface and continue at 5 feet intervals until ground water is reached. All samples are to be analysed for volatile organics according to EPA test methods 601 and 602. A complete metal scan must also be included in the ana~ sis. , 4. Two additional test holes should be placed on the east side of the sump opposite sample test holes B and C. At this time, there does not appear to be a need for sample holes E through I. These may be required at a later date should samples A through D indicate potential contamination. Samples should be collected at 5, 10 and 15 feet depths from test holes A, B, C and D. Ground water samples will be taken during the groundwater study, therefore, are not necessary at this time. DISTRICT OFFICES Delano . Lamont . Lake Isabella . Molave . flldoecr®at .

The locations of Boreholes B-2 and B-~ are appropriate as proposed· However, the depths of' the borings, should be advanced to at ~e_s ~ = ~ the groundwater table, which a previous boring }]as shown to be at about a 20-foot depth. Soil samples shculd be collected at the 3, 5, 1C, 15, and 20 fcot depths. Samnles of the grcundwater should be collected from both borings. Sample holes A, ~, C, and D should also be advanced to the groundwater table. Soil samples should be collected from the 5, 10, 15 and 20 foot depths. Two sample holes should be placed'on the east side of the pond, opposite to sample holes B snd C. Soil samples for these borin.gs should also be collected from the 5, 10, 15, and 20 foot depths. ;',"e do not anticipate the need at this ooint for proposed sample holes E +hroug~ I. However if the cost of collecting and analyzing soil samples from these proposed borings'is only incremental to the total cost of the work plan, then the additional information obtained may be cost effective. If borings F, G and H are installed, there must be 3 other borings on the east side of the nond to comoliment the contamination characterization effort. All samo!es need to be analyzed for a com?].ete heavy metal scan and volatile organics according to EPA test methods 601 and 60~. In order to achieve cost containment, composite sampling may be conducted. The ccmpositing should be performed only between samo!es collected at equivalent soil depths and each composite should not consist of more than three discrete samole components· If composite sampling is conducted, a !:ortion of each soil sample collected should be preserved should more specific site characterization analytical testing be required at a later date. If contamination of the perched groundwater is established, the direction of the 'groundwater gradient and an evaluation of the continuity of the perched ecuifer with lower groundwater zones must be determined. -2- Site safety during the execution of the Work Plan is the responsibility of thc Sa~e~y Engineer and/or Industrial Hygienist. Samples should not be capped with aluminum foil a~d cleaning of the equipment between sampling should be done with hexane or acetone. After characterization of the site has been completed, a Feasibility Study needs to be developed in which alternatives for corrective action are discussed, and a recommended cleanup.plan is presented. ~P!ease contact me should you require a clarification on any of the above items. cerely, Thomas W.

Scott Nevins Senior Engineer FROM: James Stites Staff Engineer DATE: 14 April 1992 SIGNATURE: SUBJECT: VALLEY PERFORATING COHPANY, KERN COUNTY Following receipt of Valley Perforating Company's 28 January 1992 letter, I have reviewed all available information regarding the potential impact of the Company's past disposai operations on the underlying ground water. My observations are as follows: The facility is located in an industrial area of Bakersfield. Several businesses relating to manufacturing and metal processing exist adjacent to and nearby the property. e The Company's surface impoundment was found subject to the TPCA in February 1989 because of hazardous levels of lead in the soils. e The Company has conducted a HAR, ceased discharge, and clean closed the impoundment, thus satisfying the requirements of-the TPCA. e Ground water gradients at the site shift significantly and are dependent not only on ground water withdrawal, but also on recharge from the Kern River just south of the facility. 0 The underlying ground water is of excellent quality, with beneficial uses of municipal and domestic supply, agricultural supply, and industrial process supply. Samples of ground water at the site indicate low levels (varying from non- detectable to slightly above and slightly below action levels) of trichloroethylene, tetrachloroethylene, cis-l,2-dichloroethylene, and 1,2- dichloroethane in ground water. Analyses of samples of the Company's processing fluids show no concentrations of the contaminants found in ground water. Soil samples collected and analyzed from 8 bore holes located within and/or adjacent to the impoundment show no concentrations of the contaminants found in ground water. CONCLUSIONS The assessment work conducted at the site over the last 7 years has not demonstrated that Valley Perforating has affected the underlying ground water.

SCOTT NEVINS Senior Engineer FROM: JAMES STITES Staff Engineer DATE: 26 December 1991 SUBJECT: REPORT £EVIE't/, VALLEY PERFOtZATZNGCO., KERE COLINTY I have reviewed a report that was submitted by Kenneth D. Schmidt and Associates on behalf df Valley Perforating. Work included in the report attempts to address our lg June 1991 memorandum whereupon we requested Valley Perforating to determine the vertical and lateral extent of ground water degradation that has occurred as a result of previous discharge operations to a former on-site surface impoundment. Previous investigative work performed at the facility indicates that ground water in the vicinity of the surface impoundment has been affected by several organic contaminants including TCE, PCE, cis-l,2-dichloroethylene and 1,2-dichloroethane. These contaminants have been detected in ground water in the vicinity of the former impoundment at concentrations up to 38 times the advisory level (Primary MCL). Other organic contaminants, including ethylbenzene, toluene, trans-l,2,-dichloroethylene, 1,1-dichloroethane, and 1,1-dichloroethylene have also been detected in ground water, however not at concentrations over advisory levels. In an attempt to determine the extent of ground water degradation previously detected, information provided in the report indicates that three additional monitoring wells have been installed along the northern and eastern boundaries of the property. Gradient measurements provided in the report indicate that ground water flow is toward the southwest. As such, the new monitoring wells appear to be hydraulically cross- gradient to the former impoundment. The new wells provide some information about the lateral extent of the ground water degradation at the site. Additional information is still needed, however, in the downgradient direction. Construction details of the monitoring wells are included in the report and appear to be appropriate. The ground water analyses included in the report appear to be appropriate for the contaminants of concern at the facility. The analyses indicate that tetrachloroethene was detected in MW-3 (downgradient) and MW-5 (cross-gradient) at 0.6 ug/1. No organic contaminants were detected in the other monitoring wells. The report indicates that each well was pumped with a submersible pump for two hours prior to sampling. This type of sampling raises uncertainty regarding whether or not the samples provide an accurate indication of organic contaminants in ground water. Excess sampling.agitation can lead to volatilization of organics, and purging large volumes of water can affect local ground water gradients and result in ground water samples that may not accurately represent downgradient conditions. Results of trip blanks, lab blanks and spiked samples were included in the report and appear to be adequate. VALLEY PERFORATING CO. KERN COUNTY -2- 26 December 1991 SUMMARY AND CONCLUSIONS The analyses of the samples from MW-3 an MW-5 suggest that these wells may be near the outer boundaries of the plume in a lateral direction. However, the information provided to us on the method of sample collection (excessive well purging) raises questions about whether or not this is the proper conclusion to draw from this information. Additional work is still needed to define the vertical and lateral extent of the plume of degraded ground water at the facility.

SCOTT NEVINS Senior Engineer DATE: 19 June 1991 SUBJECT: FROM: JAMES STITES Staff Engineer SIGNATURE: WORK PLAN REVIEW, VALLEY PERFORATING COMPANY, KERN COUNTY I have reviewed a work plan that was submitted by Kenneth D. Schmidt and Associates in response to our memorandum dated 22 March 1991. In that memorandum, we requested the Discharger to provide us with a work plan and time schedule to conduct work to determine the vertical and lateral extent of ground water degradation that has occurred as a result of previous disposal to an unlined on-site surface impoundment. Four monitoring wells have been previously installed in the vicinity of the backfilled surface impoundment. Ground water samples obtained from these wells have shown organic contaminants at concentrations up to 38 times the appropriate advisory level. Proposed in the work plan is the installation of three additional on-site monitoring wells. One monitoring well will be placed along the northern boundary of the facility. The second well will be placed along the western boundary of the facility and the third well will be placed in the northwest corner. The locations proposed for these wells could be useful in checking for possible contaminants from other sources. None of the wells, however, appear to be located downgradient from the former surface impoundment. As such, the work proposed does not appear to be appropriate to identify the boundary of the contaminant plume from the former surface impoundment. The design proposed in the work plan for the additional monitoring wells appears to be similar to the four existing on-site wells. The wells will be drilled to about 50 feet deep and will be screened for 25 feet, with approximately 20 feet of the screened interval below the water table'. Well installation and construction details, includi~ng a cross sectional schematic diagram, are provided in the work plan and appear to be adequate. The work plan indicates that a submersible pump will be used for pumping the monitoring wells prioff to sampling. The work plan, however, does not specify how ground water samples will be collected. The method of sample collection for volatile organics is important to ensure minimal loss of volatiles. Excessive pumping of the well during sampling could lead to an accelerated loss of volatile organic compounds. The work plan indicates that samples obtained from all seven monitoring wells (four already in place and. the three proposed wells) will be analyzed for organic constituents, inorganic constituents and other parameters such as pH, electrical conductivity and water levels. The analytical method proposed in the work plan (Method 601) appears to be appropriate for detection of organic constituents previously found in the ground water near the surface impoundment. QA/QC procedures are discussed in the work plan and include analyzing a blank sample for volatile halocarbons and maintaining sample chain-of-custody documentation. The VALLEY PERFORATING COMPANY KERN COUNTY -2- work plan, however, does not indicate whether or not trip blanks or equipment blanks will be collected and analyzed, nor does it discuss laboratory QA/QC procedures. The work plan indicates that approximately 90 days would be required to accomplish this phase of the investigative work and submit a technical report to us. This time schedule is acceptable. CONCLUSIONS Although the proposed work could provide some insight into water quality conditions upgradient from the surface impoundment, no work has yet been proposed to define the boundaries of the plume of degradation down gradient from the surface impoundment. e Reco~nended EPA procedures should be used and documented in the technical report, for all sampling, sample preservation, chain of custody, chemical analyses, use of split and spiked samples and use of trip blanks.

The revised work plan was prepared by Kenneth D. Schmidt and Associates. The revisions were prepared in response to a letter, dated 1 August 1989, from the Regional Board. In the letter, Regional Board staff commented on six different items from Valley's previous work plan for preparing a HAR and requested Valley to submit a revised work plan for developing the information to be included in the geotechnical report. It is proposed within the submitted revised HAR work plan to conduct the following.work items: Install four ground water monitoring wells around'the inactive pond (three downgradient and one upgradient). The wells will be drilled to extend about 20 feet below the water table. Drill cuttings will be logged and any unusual smells or discoloration will be noted and be reported. Collect water samples from each monitoring well and analyze them for volatile organic chemicals (EPA Methods 601, 602, and 625), metals (arsenic, chromium, and lead) and others. o Drill cuttings will be monitored with an organic vapor analyzer and the readings will be recorded on the drilling log. If evidence of contamination is encountered during drilling of the monitoring wells, soil samples will be collected and tested for metals and volatile organics. Depth to water in each well will be measured, and the elevations of the measuring points will be determined by survey. I find the proposed work plan to be acceptable except for the following item: According to the submitted work plan, the ground water flow direction is to the northwest. Data from a site 500 feet west of Valley indicates that shallow ground water is flowing to the southwest (see REVISED HAR WORK PLAN FOR VALLEY PERFORATING COMPANY, BAKERSFIELD, KERN COUNTY -2- attached figure). No data or references were provided to support Valley's statement on the direction of ground water movement. A rationale for placing three monitoring wells northwest of the inactive pond must be provided. If these wells do not adequately define the direction of ground water flow and ground water conditions upgradient and downgradient of the site, then additional monitoring wells will be required. I have no objection to Valley implementing their work plan proposal, provided they incorporate a response to the above comment in their proposal. JYH:cjs EOF AT._ CAL,~:O~NIA GEORGE DEUKMEJIAN.

Kern County Health Oel~L Mr. Jerry Reynolds Valley.Perforating Company 3201 Gulf Street Bakersfield, CA 93308 VALLEY PERFORATING COMPANY, BAKERSFIELD, KERN COUNTY We have reviewed your report, dated 5 April 1989, regarding the ground water investigation work plan for the subject facility. Enclosed is a memo containing our comments. Because of the uncertainty of the ground water conditions under your inactive pond, you need to install at a minimum one upgradient and three downgradient monitoring wells. You may need to install monitoring wells in the water table aquifer, if the perched water aquifer can not.be shown to be continuous and/or is degraded. Prior to 31 August 1989, please provide us with a revised work plan for developing the information to be included in the geotechnical report. The work plan should be prepared under the direction of a registered engineer or engineering geologist and should reflect all the comments contained in the attached memorandum. The work plan should provide sufficient detail to allow us to determine the adequacy of the proposed study and should include a time schedule for conducting the study and submitting the report.

Han Staff Geologist DATE: SUBJECT: 1 August 1989 SIGNATURE:///~/'/~/~:"'.//~/'/~" REVIEW OF PROPOSED HAR WORK PLAN FOR VALLEY PERFORATING COMPANY, BAKERSFIELD, KERN COUNTY I-have reviewed the work'plan for a Hydrogeologic Assessment Report (HAR) dated 5 April 1989, which was submitted by Kenneth D. Schmidt and Associates for Valley Perforating Company (hereafter Valley). The report was prepared in response to a request from the Regional Board staff. In a letter dated 2 February 1989, the Regional Board staff stated that Valley's inactive pond is subject to the Toxic Pits Cleanup Act (TPCA) of '1984 and requested that Valley submit a HAR and pay appropriate TPCA fees. It is proposed within the submitted HAR work plan to conduct the following work items at the site: Install three ground water monitoring wells around the inactive pond (two downgradient and one upgradient). Each well will be drilled to a depth of about 40 feet. The perforated casing will extend from about five feet above the water table to the bottom of the well. Collect water samples from each monitoring well and analyze them for metals and volatile organic chemicals (EPA Methods 601 and 602). Collect and report the locations and construction details of the area water wells, and test some of the wells for possible pollution from Valley's pond. I have the following six comments on the proposed work plan: According to the results of the previous investigations (two reports dated September 9, 1985 and February 26, 1986 from Valley) a total of eight soil borings were drilled under and around the pond during 1985 and 1986. Seven of the borings were drilled down to a depth of 16 feet or 17 feet, and one boring was drilled to a depth of 30 feet. Three of the eight borings encountered a wet zone between 13.5 and 19 feet deep. The reports did not describe the amount of moisture they found in the wet zones. According to the ground water level maps in the Water Supply Reports of 1986, REVIEW OF PROPOSED HAR WORK PLAN FOR VALLEY PERFORATING COMPANY, BAKERSFIELD, KERN COUNTY -2- 1987, and 1988 (published by Kern County Water Agency), Valley is located close to but outside of, an area with a continuous perched ground water body. There is little site specific information on the existence of perched ground water under Valley. If Valley cannot demonstrate that the perched water under Valley is continuous and has not been degraded, then additional monitoring wells will be required in the water table aquifer. According to the submitted work plan, the ground water flow direction is to the northwest. No data or references were provided to support their statement on the direction of ground water movement. At a minimum, Valley should install one upgradient and three downgradient monitoring wells. The monitoring wells should be placed near the pond area to provide early detection of contaminant leakage. The ground water flow direction should be determined through water level measurement of all the monitoring wells at least bimonthly for a one year period. If evidence of contamination is encountered during drilling of the monitoring wells, soil samples should be collected and tested for metals and volatile organics. The drilling log should indicate if the cuttings exhibit any unusual smells and/or discoloration. Cuttings should be monitored with an organic vapor analyzer and the readings recorded on the drilling log. In addition to EPA Methods 601 and 602, ground water should be tested for base/neutral organic compounds (EP% Method 625). The work plan contains a proposal for analyzing ground water for metals. The metals to be analyzed for and EPA Methods to be used are not listed. These should be provided.

CALIFORNIA 93726 PHONE: (209) 445-5116 2 February 1989 e Jerry Reynolds, President Valley Perforating Co. 3201 Gulf Street Bakersfield, CA 93308 VALLEY PERFORATING COMPANY, REPORT OF INSPECTION Enclosed for your information is a copy of a report of inspection of the Valley Perforating Company in Bakersfield. You were present during the inspection. Two soil samples from the unlined pond bottom were analyzed by BC Laboratories in May 1985. High levels of total lead (760 and 3,680 mg/kg) and soluble lead (56.8 and 250 mg/1) were found (for the test result's see Figure 7 in the BSK and Associates' work plan dated 28 August 1985). The concentration of total lead exceeded the TTLC value of 1,000 mg/kg in one sample, and the concentration of soluble lead exceeded the STLC value of 5 mg/1 in both samples; we conclude that the pond contained hazardous waste after 1 January 1985. The pond is open to precipitation. According to the BSK & Associates' report, dated 26 February 1986, the water line in the pond was approximately 2 feet below ground surface during December 1985. In accordance with Section 25208.4, Title 22, California Code of Regulations, a pond containing hazardous waste in contact with free liquids after 1 January 1985, is subject to the Toxic Pit Cleanup Act of 1984. We, therefore, have determined that your inactive pond is subject to the Toxic Pit Cleanup Act (TPCA) of 1984. Since your inactive unlined pond is a toxic pit, you are responsible for two fees: an initial fee of $1,500 ; and an annual fee of $3,000. Your check for the total amount of $4,500 should be made payable to the State Water Resources Control Board, and submitted to this office. THIS LETTER IS THE OFFICIAL NOTICE OF FEES DUE AS REQUIRED BY SECTION 25208.3 (c) OF THE HEALTH AND SAFETY CODE. IF YOUR FEE IS NOT PAID WITHIN 60 DAYS AFTER RECEIPT OF THIS NOTICE, A PENALTY OF 1 PERCENT PER DAY, UP TO 100 PERCENT OF THE TOTAL FEE WILL BE ASSESSED. The fees are to cover the costs incurred by the State and Regional Boards in carrying out their responsibilities under the TPCA. Such responsibilities include reviewing hydrogeological assessment reports, and conducting inspections. Records are kept for each facility; and VALLEY PERFORATING CO. -2- 2 FEBRUARY 1989 if the actual costs for your facility exceed the fees collected, the State Board will bill you for the balance. If actual costs are less than fees collected, the State Board will refund the excess fees collected. It is also necessary that you submit a hydrogeological assessment report (HAR) to this office. A check list of each item to be included in the HAR is enclosed for your convenience. Prior to 6 March 1989, please provide us a work plan for developing the information to be included in the HAR. The work plan should provide sufficient detail to allow us to determine the adequacy of the proposed study and should include a time schedule for conducting the study and submitting the report(s).

VALLEY PERFORATING CO. -2- INSPECTION REPORT PREINSPECTION FILE REVIEW Valley Perforating Company (hereafter Valley) is located at the end of Gulf Street, east of Pierce Road in northwest Bakersfield. Valley manufactures slotted well pipe for various oil industry usages. Valley began operations in the early 1960's and was purchased by the present owner in 1970. Pipe is cut with saws. The saw blades are cooled and lubricated with cutting oil. Oil and cuttings remaining on the pipe walls are removed by pressure steam cleaning. In addition to cutting oil, Valley used thinner, and lubricating oil in their milling and perforating process. A review of the Regional Board case file for Valley indicates that from 1964 the plant discharged waste water from the steam cleaning process to an unlined drainage sump located behind the main building. The drainage sump measures approximately 30 X 50 feet and is about eight feet deep. Two soil samples from the unlined pond bottom were analyzed by BC Laboratories in May 1985. High levels of total lead (760 and 3,680 mg/kg) and soluble lead (56.8 and 250 mg/1) were found (for the test results, see Figure 7 in the BSK and Associates' work plan dated 28 August 1985). The date the two soil samples were collected was not specified in the report, but since the samples were received on 17 May 1985, we assume that the samples were collected after 1 January 1985. The concentration of total lead exceeded the TTLC value of 1,000 mg/kg in one sample, and the concentration of soluble lead exceeded the STLC value of 5 mg/1 in both samples; we conclude that the pond contained hazardous waste after 1 January 1985. The pond is open to precipitation. According to the BSK & Associates' report (page 2), dated 26 February 1986, the water line in the pond was approximately 2 feet below top of ground surface during December 1985. In accordance with Section 25208.4, Title 22, California Code of Regulations, a pond containing hazardous waste in contact with free liquids after 1 January 1985, is subject to the Toxic Pit Cleanup Act of 1984. In a letter dated 11 February 1985, the Kern County Health Department indicated that an additional soil sample had been collected. The soil sample results are presented in Figure 4 of BSK & Associates' work plan dated 28 August 1985. The sample was received by BC Laboratories on 11 December 1984. The concentration of soluble lead was found to be 46.6 mg/1. This sample result exceeded the STLC value of 5 mg/1 as listed in the California Code of Regulations, Title 22. VALLEY PERFORATING CO. -3- Valley retained BSK & Associates to establish a work plan and conduct a site investigation. On 24 August 1985, a single test hole (B-i) was drilled about 60 feet southwest of the pond. B-1 was drilled to a depth of 30 feet. Petroleum odor was detected in the top two feet of soil. Perched ground water was encountered 19 feet below existing ground level. The water table is at a depth of approximately 55 feet. The soil at the site consists of fine to medium grained sand with occasional lenses of silt. The soils from surface to 13 feet depth contain significant amounts of silt. Between 13 and 30 feet, the soils grade to moderately clean sand with some gravel and silt lenses. In a letter dated 22 October 1985, the Regional Board recommended that Valley analyze all soil samples for a full range of heavy metals and volatile organic chemicals. The Regional Board also recommended that ground water be evaluated for leakage of heavy metals and volatile organic chemicals from the pond. During December 1985, and January 1986, Valley drilled seven soil borings in the pond area. The borings ranged from 16 to 17 feet in depth. A sketch showing the location of the borings is attached (plate 1). Borings B-2 and B-3 were drilled on a 45 degree slant under the pond bottom. According to drilling logs, strong petroleum odor was noted between 5 and 10 feet in Boring B-2 and at 13 feet in Boring B-3. Boring R H-1 was drilled approximately 1,500 feet north of the pond. Boring RH-1 was drilled to establish background. Boring A was drilled about 20 feet north of the pond. Borings B and C were drilled 10 feet west of the pond. According to drilling logs strong petroleum odor and discoloration were noticed at about 15 feet in both borings B and C. Boring D was drilled about 15 feet south of the pond. During December 1985, and January 1986, 27 soil samples were collected from the soil borings. The soil samples were tested for volatile organics using EPA test methods 8010 and 8020. All the test results showed below detection limits of 0.50 mg/kg. Soil samples were also analyzed for 17 metals. The test results indicated elevated concentrations of arsenic, chromium, lead, barium, and vanadium in soils under the disposal pond. The chemical analysis results of arsenic, chromium, and lead for soil samples from different depths are listed in attached table 1. Up to 29.5 mg/kg of arsenic, 26.4 mg/kg of chromium, and 23.2 mg/kg of lead were found in soil samples from the soil borings. Ground water was encountered between 17 and 19 feet in borings RH-1, A, and B-1. No ground water samples were collected for chemical analysis. VALLEY PERFORATING CO. -4- INSPECTION On 21 November 1988, Robert Turner and I inspected Valley. We were accompanied by Mr. Jerry Reynolds, owner of Valley, Mr. Mike Dover, vice president of Valley, and Mr. Sam Hayward, Valley's consultant for waste water. Mr. Reynolds informed us that Valley ceased discharging waste to the pond in December 1984. Mr. Reynolds also informed us that the waste water generated by the steam cleaning operation is currently stored in two 12,000 gallon above ground tanks and disposed offsite. At the time of our inspection, waste water was not entering the unlined pond and the bottom of the pond was dry. The pond walls and bottoms were discolored from previous discharges. Soil scraped from the surrounding land had been placed in the southern end of the pond. During this inspection, we collected a ground water sample from Valley's on-site water supply well which is west of the main building. According to the information available from Valley's case file, the well is approximately 160 feet deep, and the standing water level was 54 feet deep from ground surface during August 1988. I delivered the water sample to Twining Laboratories on 22 November 1988 to be analyzed for volatile organics using EPA test methods 601 and 602. The analysis results indicate that all constituents tested for are below detection limits. The chemical analysis results are attached. DISCUSSIONS AND REQUIREMENTS The discharge to the surface impoundment ceased in December 1984. The soil near the pond is contaminated with metals. Ground water was not tested for contaminants. The surface impoundment has been abandoned without proper closure. The pond contained hazardous waste in contact with free liquid after 1 January 1985. Therefore, the pond is subject to the Toxic Pit Cleanup Act (TPCA) of 1984. The TPCA requires following items; 1. Pay fees established by the State Water Resources Control Board. The fees are to cover the cost incurred by the State and Regional Boards in carrying out their responsibilities under the TPCA. 2. Submit a hydrogeological assessment report (HAR) to the Regional Board. A check list of each item to be included in the HAR is enclosed. Work completed to date may be used for the HAR; however, that work must be clearly referenced or be resubmitted with the HAR. VALLEY PERFORATING CO. -5- 3. The inactive pond should be closed properly. Valley should establish and submit a pond closure plan. Closure and monitoring shall be in accordance with California Code of Regulations, Title 23, Chapter 3, Subchapter 15 requirements. JYH
