These activities include the excavation and bioremediation approximately 4,500 cubic-yards of soils impacted with petroleum hydrocarbon compounds associated with three earthen clarifiers connected to a truck wash rack as well as excavation and use as dust control cover of approximately 2,500 cubic yards of an asphaltic petroleum hydrocarbon impacted soil associated with the former operation of three tanker truck bottoms disposal pits recently documented by ESE in the above referenced report. Don Kieth Transportation 2 October 20, 1992 1.0 Introduction Excavation at the site began on September 8, 1992 and initially concentrated on the two tanker truck bottoms disposal pits in the rear of the property (Figure 2). During excavation an additional pit was discovered. Due to this discovery, and the Kern County' Resources Management Agency - Department of Environmental health Services' (KCDEHS) request that the excavation be conducted to a depth of 20 feet below surface grade, the volume of soil excavated was increased to approximately 3,000 cubic yards over an area 100 feet north to south and 50 feet east to west. Laboratory analysis has verified no detectable concentrations beyond these limits (see Appendix A). The excavation pit has subsequently been backfilled with import material, compacted to greater than 90% maximum density, and returned to surface grade. Approximately 1,500 cubic yards of the excavated material consists of asphaltic residue mixed with .sandy soil. Similar material has been previously stockpiled on site which was determined by the Regional Water Quality Control Board - Central Valley Region to be suitable for use as a dust control material for the property. The KCDEHS has concurred that the newly excavated material is of a similar nature and is therefore' also suitable for dust control following the same proscribed criteria of an apPlication not to exceed three inches in thickness. The other 1,000 cubic yards is a low level petroleum hydrocarbon impacted silty sand material which is being successfully bioremediated on site. Bioremediation will continue until the concentrations are less than 100 mg/kg for total extractable petroleum hydrocarbons as diesel. The treated soil will then be used as grading fill material on site. Upon completion of the excavation of the tank bottoms pits, focus shifted to the wash water earthen clarifiers in the center of the property (Figure 2). Excavation preceded to the dimensions contained in the original work plan of 75 feet east to west by 40 feet north to south for a volume of petroleum hydrocarbons impacted sandy EB-8228-3 9210-E015.RPT Don Kieth Transportation 3 'October 20, 1992 and silty sand soil of approximately 2,250 cubic yards. Soil sampling verified clean sidewalls for the clarifier excavation with the exception of the northeast comer of the excavation (see Appendix B). In this location a 12 inch diameter pipe was -- observed leading to the nOrtheast, and surrounded by a halo of petroleum impacted soil. Excavation was initiated on September 18, 1992 to expand the pit in this direction. It was soon discovered that a third chamber to the clarifier system was present to the north and east of the original two chamber clarifier (Figure 2). Excavation has continued in this area through September 22, 1992 to establish the dimensions of this third chamber. The third chamber appears to have been very similar in size to the original excavation, and also involves approximately 2,250 cubic yards of slightly impacted soil. Soil sampling has been conducted which ve~'ified clean sidewalls for the third clarifier excavation (see Appendix B). The excavation pit has subsequently been backfilled with import material, compacted to greater than 90% maximum density, and returned to surface grade. The 4,500 cubic yards of petroleum hydrocarbon impacted soil from the three chambers is being bioremediated on site. Bioremediation will continue until the concentrations are less than I00 mg/kg for total' extractable petroleum hydrocarbons as diesel. The treated soil will then be used as grading fill material on site. The soil undergoing bioremediated has been placed as a one foot layer on the property. Treatment of the soil has consisted of enhancing indigenous soil microbes through the oxygenation effects of mechanical cultivation. Three soil samples have been collected from treatment cell and analyzed for the presence of TEPH as diesel, and TRPH as oil and grease. The analytical results indicate that the mechanical cultivation has been moderately successful in reducing the concentration of these petroleum hydrocarbons. · /~ESE is currently r~ecommending that this process be accelerated through nutrient conditioning. This will consist of the addition of a time released nitrogen/phosphorous application to establish a weight ratio of carbon: 106, nitrogen:16, and phosphorous:l which has been shown to yield optimum EB -8228 -3 9210-E015.RPT Don Kieth Transportation 4 October 20, 1992 biodegradation rates in similar petroleum hydrocarbon impacted soil. The carbon weight is based on the concentration of hydrocarbons in the soil. ESE recommends the application of two pounds of N:16/P:I nutrients per cubic yard of impacted' soil. Application will be in dry form using a spreader and tilling into the soil. This will be followed by moisture conditioning using a water truck, and a second round of tilling. c.e.c~s that the treatment in the form of mechanical cultivation and. periodic~rnoi~ture ecmditi~oning using a water truck should then continue for a period of two to three months. During this time frame samples will be collected from the treatment cell t% monitor the progress of reducing TEPH as diesel to below 100 mg/kg_~ When the concentrations have been reduced to below this recommended guideline, c~onfirmation sampli~ng will be conducted in the presence of the KCDEHS representative. ESE recommends that a grid be established so that a sample is collected for each 50 cubic yards of impacted soil and that these samples then be cOmposited in the laboratory at a 4:1 ratio and analyzed for the presence of TEPH as diesel. This will result in an estimated 25 samples for laboratory analysis. Upon verification of successful treatment, ESE will recommend that the soil be removed from the treatment cell, and spread as grading fill on the property. ESE will subsequently recommend that the site be considered for closure. All methods employed by ESE for this remediation are in compliance with regulations and guidelines set forth in California Code of Regulations (CCR) Title-22, ArtiCle 11, and Title 23, Chapter 3, California Site Mitigation Decision Tree Manual, the Code of Federal Regulations (CFR) Title 29, Part 1910, Section 120, CFR Title 40, Parts 300-399, and San Joaquin Valley Unified Air Pollution Control District, Kern County Zone Rule 463.5, as well as accepted professional environmental/geotechnical engineering procedures and applicable local regulations. EB-8228-3 9210-E015.RPT Don Kieth Transportation 5 October 20, 1992 O The work plan employed by ESE to date to excavate and treat the petroleum impacted soils has included: · Preparation of a site Health and Safety Plan in accordance with regulations set forth in Federal OSHA CFR 29 1910.120, as well as California OSHA regulations. · Excavation of approximately 4,500 cubic yards of impacted soil beneath the location of the former truck wash clarifiers.' · Excavation of approximately 2,500 cubic yards of soil and sludge materials within the former tanker truck bottoms disposal pits. · Confirmatory sampling and analysis of the excavation pit bases and sidewalls. · Backfilling the pits with "clean" import fill material, compacting, and returning to surface grade. · Stockpiling the tank bottoms soil and sludge on site for later application as a three inch dust control cover. · Placement of the clarifier impacted soil in a twelve inch lift over the rear portion of the property. · Mechanical cultivation increasing oxygenation and enhancing indigenous soil microbes to reduce the concentrations of the petroleum hydrocarbons to beneath RWQCB recommended guidelines. · Progress monitoring and sampling. · Preparation of this report documenting ongoing remediation activities. 2.0 Health & Safety Plan A written Health and Safety plan was implemented for site work conducted during the mitigation phase of this project. The purpose of the plan was to provide specific safety procedures to be implemented during the handling' of petrgleum hydrocarbon contaminated materials. The Health .and Safety Plan was required under regulations set forth in Federal OSHA CFR 29 1910.120, since the referenced reports documented the presence of potentially hazardous materials at the site. -- EB-8228-3 9210-E015.RPT Don Kieth Transportation 6 October 20, 1992 3.0 Soil Excavation · Kern Environmental Services provided front end loaders, and an excavator to remove the estimated 2,500 Cubic yards of impacted soil and asphaltic sludge from the three tank bottoms disposal pit in the rear of the property, and 4,500 cubic yards of petroleum impacted soil from the three truck wash earthen clarifiers in the central portion of the property (Figure 2). Excavation was conducted on the days of September 8 through September 21, 1992. Prior to excavation, Underground Service Alert (USA) was notified 48 hours in advance. In addition, the excavation contractor obtained necessary excavation permits from California Occupational Safety and Health Administration (Cai OSHA). Petroleum impacted soils in the areas identified by the ESE Site Assessment Study dated August 12, 1992 were removed by excavating with front end loaders, and an excavator. The impacted soil has been segregated into two stockpiles. One stockpile consists of 1,500 cubic yards of soil and asphaltic sludge from the tank bottoms disposal pits. This material has been thoroughly mixed with the solid asphaltic material pulverized using a Bomag Reclaimer so that no fragment exceeds 2 1/2 inches in diameter. This material will eventually be applied for dust control to the rear two thirds of the property at a thickness not to exceed three inches (Figure 2). The second stockpile consists of 5,500 cubic yards of petroleum impacted soil generated from the peripheral edges of the tank bottoms disposal pits and the truck wash earthen clarifiers. This material has been placed within a remediation cell covering the rear two thirds of the property using a rubber tire front end loader. Excavating proceeded at the location of the tank bottoms disposal pits~L..~ ,t~?h ~_~ ~0 feet below surface grade over an area 100 feet north to south and 50 feet east to west (Figure 2). Excavating proceeded at the location of the truck wash earthen clarifiers to a depth of 20 feet below surface grade over an area 75 feet east to west by 40 feet EB-8228-3 9210-E015.RPT Don Kieth Transportation 7 - October 20, 1992 north to south at the two southwestern clarifiers; and to a depth of 23 fee__.__.~t below surface grade over an area 75 feet east to west by 40 feet north to south 'at the northeastern clarifier (Figure 2). The excavation was performed so that sidewall slopes conformed to California and Federal OSHA code requirements. 4.0 Excavation Pit Field Screening During excavatiOn soil samples were collected from the base and sidewalls of the excavation pit and were visually screened for the presence of petroleum hydrocarbons. Excavation was continued until there was no evidence in the sidewalls and pit base of stained soils, or soils containing petroleum odors. Integration of the final dimensions of the excavated pit with data collected from the previous site characterization at the property indicated that no concentrations of TEPH as diesel or TRPH as oil and grease in excess of 100 mg/kg should be remaining -in the subsurface. Confirmation soil samples have been collected under the direction of a KCDEHS representative from the boundaries of the excavations to verify satisfactory removal of the impacted soil. 5.0 Soil Sample Collection Six verification soil samples were collected from the base and sidewalls of the tank bottoms excavation pit at the locations shown on Figure 3. One soil sample was collected from each of the four sidewalls at a depth of 10 feet below surface grade, and two soil samples were collected from the base of the excavation. Ten verification soil samples were collected from the base and sidewalls of the southwestern truck wash earthen clarifier excavation pit at the locations shown on Figure 4. Two soil samples were collected from each of the four sidewalls at a depth of 10 feet below surface grade, and two soil samples were collected from the base of the excavation. EB -8228 -3 9210-EO 15.RPT Don Kieth Transportation 8 October 20, 1992 Five verification soil samples were collected from the base and sidewalls of the northeastern truck wash earthen clarifier' excavation pit at the locations shown on Figure 4. One soil sample was collected from each of the three sidewalls (no south sidewall is present due to adjacent clarifier excavation) at a depth of 10 feet 'below surface grade, and two soil samples were collected from the base Of the excavation. Undisturbed soil samples were obtained by driving a modified Shelby Tube sampler containing stainless steel sleeves with a weighted sliding hammer. The soil samples were immediately sealed with Teflon®. liners, capped, labeled, and placed on ice for transport to a California Department of Health Services (DOHS) certified laboratory. Strict chain of custody procedures were utilized for all samples collected to ensure sample integrity and to document sample possession from the time of collection to the final destination. 6.0 Laboratory Analysis: Excavation Verification Soil Samples The soil samples were analyzed at BC Laboratories, a State of California certified laboratory for total recoverable petroleum hydrocarbons as oil and grease using USEPA Test Method 418.1. The analytical reports for the tank bottoms excavation are included as Appendix A, the southwestern truck wash clarifiers as Appendix B, and the northeastern truck wash clarifier as Appendix C. 7.0 Analytical Results - Excavation Pits All of the six soil samples from the tank bottoms excavation were non detected for TRPH as oil and grease. Five of the soil samples from the southwestern truck wash earthen clarifiers were non detected for TRPH as oil and grease. One of the samples detected TRPH as oil and grease at a concentration of 40 rog/kg. The samples from the northeastern portion of the excavation detected TRPH as oil and grease at a concentrations of 3,400 mg/kg, and 700 rog/kg. This corner was subsequently excavated when the northeastern clarifier was removed. Four of the five soil samples collected from the northeastern truck wash clarifier excavation were non detected for TRPH as oil and grease. One of the soil samples from the northeastern clarifier detected TRPH as oil and grease at a concentration of 20 mg/kg.

Note: The soil in excess of the RWQCB recommended guidelines indicated in the samples from the eastern and northeastern sidewalls of the southwestern clarifiers (8287-8 & 9) was removed with the excavation of the northeastern elarifier. EB-8228-3 9210-E015.RPT Don Kieth Transportation 1 0 October 20, 1992 8.0 Backfill and Compactio, n Upon review of the laboratory results, and with the approval of the' KCDEHS, the excavation Pits resulting from soil removal was baekfilled from September 22 through October 8, 1992 with_ "cl~n" import soil.to replace the removed impacted soil. The soil was compacted to 90% relative compaction in 12 inch lifts under the direction of an on-site soils engineer. Compaction tests were performed at one foot intervals from the base of the excavation to surface grade. Backfilling was accomplished using an 815 mechanical compacter, a 966 loader, and a water truck. A report was prepared by the Earth Systems' civil engineering division which .certifies that the excavation was backfilled in such a way that the compaction exceeds 90%. This report is included as Appendix D, and provides the compaction test reports as documentation. 9.0 Bioremediati0n Design, Management, and Monitoring The 5,500 cubic yards of petroleum impacted soil excavated from the site was placed as a one foot thick lift over the rear two thirds of the property. The bioremedial system Utilizes active mechanical cultivation by a tractor and plow combination On a~.~daily ~ A significant decrease in the concentration of the petroleum hydrocarbons through aeration, and oxygenation can be expected through the mechanical cultivation of petroleum hydrocarbons with the molecular weight of diesel. However, the heavier molecular weight asphaltic hydrocarbons will not achieve significant decreases without aggressive enhancement of the biological degradation process. A recommended treatment guideline of 100 mg/kg has been established in conjunction with the KCDEHS. It is ESE's opinion that to obtain these cleanup concentrations without nutrient conditioning to enhance the biological processes will require a time frame in excess of four months. Upon completion of the treatment, receipt of confirmation laboratory analysis, and the approval of KCDEHS, the treated soil will be used as grading fill on the property. EB -8228-3 9210-E015 .RPT Don Kieth Transportation 1 1 October 20, 1992 The remaining 1,500 cubic yards of asphaltic, residuals from the tank bottoms pits has been thoroughly mixed with the solid asphaltic material pulverized using a Bomag Reclaimer so that no fragment exceeds 2 1/2 inches in diameter. This material has been stockpiled at the rear of the facility and will eventually be applied for dust control to the rear two thirds of the property at a thickness not to exceed three inches. 10.0 Progress Soil Sampling The progress of the treatment has been monitored periodically by field screening for visual signs of staining, and diesel odors. Five compOsite soil samples have been collected from locations within the treatment cell, each representing a portion of the soil which has been exposed to mechanical cultivation for a different time interval. Undisturbed soil samples were .obtained by driving a modified Shelby Tube sampler containing stainless steel sleeves with a weighted sliding hammer, immediately sealed with Teflon® liners capped, labeled, and placed on ice for transport to a ' California Department of Health Services (DOHS) certified laboratory. Strict chain of custody procedures were utilized for all samples collected to ensure sample integrity and to document sample possession from the time of collection to the final destination. 1 1.0 Laboratory Analysis of Treated S0ii The five soil samples were analyzed at BC Laboratories, a State of California certified laboratory for total recoverable petroleum hydrocarbons as oil and grease by USEPA Test Method 418.1. Three of the soil samples have also been analyzed for the presence of total extractable petroleum hydrocarbons as diesel by USEPA Test Method 8015 (modified for diesel). The analytical reports are included as Appendix E. -- - EB -8228-3 9210-E015.RPT Don Kieth Transportation 1 2 October 20, 1992 O 12.0 .Analytical Results - Treated Soil All five of the soil samples detected the presence of TRPH as oil and grease, and the .... three samples analyzed for TEPH as diesel detected those hydrocarbons. TRPH as oil and grease was detected at a concentration of 1,900 rog/kg in the soil which has been treated the shortest duration, and decreased to 380 rog/kg in the soil which has been treated the longest duration. TEPH as diesel was detected at a concentration of 2,000 rog/kg in the soil which has been treated the shortest duration, and decreased to 200 mg/kg in the soil which has been treated the longest duration.

EB-8228-3 9210-E015.RPT Don Kieth Transportation 1 3 October 20, 1992 O 13.0 Conclusion No soil with concentrations of petroleum hydrocarbons in excess of RWQCB recommended guidelines are known to exist in the subsurface at the location of the -- ~former tank bottoms disposal pits, or truck wash earthen clarifiers. No additional soil mitigation is deemed to be necessary in these locations. The bioremediation of the impacted soil through mechanical cultivation enhancing oxygenation has reduced the concentration of diesel hydrocarbons in the soil. 14.0 Recommendations ESE recommends that the bioremediation process be accelerated through nutrient conditioning, t~'~'his will consist of the addition a time released nitrogen/phosphorous application to establish a weight ratio of carbon:106, nitrogen:16, and phosphorous:l which has been shown to yield optimum biodegradation rates in similar petroleum hydrocarbon impacted soil. The carbon weight is based on the concentration of hydrocarbons in the soil. ESE recommends the application of two pounds of N:16/P:I nutrients· per cubic yard of impacted soil. Application will be in dry form using a spreader and tilling into the soil. This will be followed by moisture conditioning using a water truck, and a second round of tilling. · ESE recommends that the treatment in the form of mechanical cultivation and periodic moisture conditioning using a water truck should then continue ~'or a period of two to three months. During this time frame samples will be collected from the treatment cell to monitor the progress of reducing TEPH as diesel to below 100 mg/kg. When the concentrations have been reduced to below this recommended guideline, confirmation sampling will be conducted in the presence of the KCDEHS representative. ESE recommends that a grid be established so that a sample is collected for each 50 cubic yards of impacted soil and that these samples then be eomposited in the laboratory at a 4:1 ratio and analyzed for the presence of TEPH as diesel. This will resUlt in an estimated 25 samples for laboratory analysis. Upon verification of successful treatment, ESE will recommend that the soil be removed from the treatment .cell, and spread as grading fill on the property. .... EB-8228-3 9210-E015.RPT Don Kieth Transportation 14 October 20, 1992 The remaining 1,500 cUbic yards of asphaltic residuals from the tank bottoms pits has been thoroughly mixed with the solid asphaltic material pulverized using a Bomag --- Reelaimer so that no fragment exceeds 2 1/2 inches ~in diameter. This material has been stockpiled at the rear of the facility and will eventually be applied for dust control to the rear two thirds of the property at a thickness not to exceed three inches. ESE will subsequently recommend that the site be considered for closure. 15.0 Closure This report has been prepared for the exclusive use of KES, HEI, and Don Keith Transportation as it pertains to the location of the former truck wash earthen clarifiers, and tank bottoms disposal pits at 2990 Pierce Road, Bakersfield, California. The results contained in each verbal or written report are based upon the information acquired during the assessment. It is possible that variations could exist beyond points explored during the course of the investigation. Also, changes in conditions found could occur at some time in the future due to contaminant migration, variations in rainfall, temperature, and/or other factors not apparent at the time of the field investigation. This report should not be regarded as a guarantee that no further contamination, beyond that which may have been 'detected within the scope of this study, is present on or beneath the site. If additional information regarding the possible presence or past use of hazardous materials at the site becomes available, then the need for further field investigation should be re- evaluated. Similarly, if suspected contamination is encountered during earthwork or construction activities, a qualified engineer or geologist should be on-site to monitor the soils and collect samples for laboratory analysis. The services performed by ESE were conducted in a manner consistent with the level of care and skill ordinarily exercised by members of our profession currently practicing under similar conditions in the state of California. No other warranty is expressed or implied. EB-8228-3 9210-E015.RPT Don Kieth Transportation 1 5 October 20, 1992 Thank you for this opportunity to be of service.

Box 5337 Bakersfield, CA 93388 Project: Don Keith Trucking Subject: Report of Observation and Testing During Excavation Backfill Submitted herewith is the final report of testing and continuous observations performed during the backfill at the above referenced project_ Backfill operations were performed by Kern Environmental Service using conventional heavy equipment Testing was performed per the authorization of Chris DeArmon, ~ Operation Supervisor. Test results and locations are presented on the attached test report summary sheets. Compaction tests were performed in accordance with ASTM D 2922-81 and ASTM D 3017-8~, Nucloar ~ty Tost Method. The maximum density and optimum moistures were determined in the laboratory in accordance with A~TM D 1557-78, Metho(t A. Te~ results are as follows: Soil Description USCS Maximum Density-Optimum Moisture Tan slightly clayey, SC 124.0 11.0 (not used) silty medium to coarse sand. Tan slightly silty sand SM 123.0 9.5 Light tan clean fine sand lll0 8.0 Discussion: 1. The scope of Our work was to test the compaction of the backfill material being placed in the previously excavated oily sump areas. 2. The project is located at 2990 Pierce Road, Bakersfield, California. Kern Environmental Service -'Job No. S-20430-B01 Odo~r 20,1992 3. The proposed use of the site will be for parking area. 4. Areas to receive f'dl were processed by scarification, moisture conditioning and recompaction. 5. Soils previouslY removed from the excavated areas were not used in the backfdl operation. 6. Fill materials consisting of import soils wore placed in thin layers and compacted into place. 7. Fill materials were compacted using conventional heavy equipment. 8. Areas not achieving minimum density requirements were reworked and retested until the desired densities were obtained. 9. Fill placed on slopes were keyed and benched into firm natural ground. The keyways were banked into the slope. 10. A total of sixty-four (64) density tests were performed. 11. Test results indicate that a minimum of ninety (90) percent of maximum dry density has been obtained in the areas tested. 12. Locations and elevations of in-sim tests were determined in accordance with their importance and accuracy and proximity of provided survey control. Unless otherwise noted, their locations and elevations were determined by pacing and visual sighting. 13. Based upon continuous observations and testing during the backfill operations from September 28 1992 through October 7, 1,992 on this project, it is our opinion that the job requirements have been met. 14. We make no warranty expressed or implied, except that our services were performed in accordance with engineering principles generally aCCepted at this time and location. 15. As used herein, the term "observation" applies only that we observed the progress of work we agreed to be involved with, and .performed tests on which we based our opinion as to whether the work essentially complies with the job requirements. 16. With any manufactured product, there are statistical variations in its uniformity, and in the accuracy of tests used to measure its qualities. As compared with other manufactured products, field construction usually has wider fluctuations in both product and test results. Thus, even with very careful observation and testing, it cannot be said that all parts of the product EARTH SYSTEMS CONSULTANTS Kern Environmental Service Job No. S-20430-B01 Odo~r 20. kq92 comply with the job requirements. Therefore, our opinion, based on observing 'and testing the work, means only that we performed our services in such a manner as to have reasonable certainty that the work essentially complies with the job requirements.
