I I February 18, 1998 I Water Quality Control Board Regional 3614 East Ashlan Avenue i Fresno, CA 93726 Attn.: Hassan Jakhar i Subject: Sampling Report For Bioremediated Soil Tract 5426 I Cladham Common Drive Bakersfield, California I Mr. Jakhar: This Sampling Report is submitted by Soils Engineering, Inc. (SEI) following the completion of I sampling the bioremediating soil in the two biocells at the subject site (see Plate 1 for Location Map). The hydrocarbon impacted soil in the two (2) biocells were sampled to evaluate the latest' hydrocarbon concentrations in the soil. A Workplan for The Disposition of this soil dated February 12, 1998 was verbally approved by Hassan Jakhar of the Regional Water Quality Control Board on February 13, 1998 and by Howard Wines of the City of Bakersfield Fire Department Environmental Services (FDES) on February 12, 1998. This soil is to be used as backfill material in sewer line I trenches on the subject site (see Plate 2 for Plot Plan). FIELD WORK CONDUCTED I Previous Sampling Events Of Bioremediating Soil Three (3) series of composite soil sample collection events have occurred at the biocells to evaluate I the progress of the bioremediation. The sampling events have consisted of collecting 4 soil samples from each 1/4 section of the bio cells and combining them into 1 sample for analysis. The composite i soil samples have been analyzed for Total Recoverable Petroleum Hydrocarbons (TRPH)~. heterotrophic plate counts, and total nitrogen and total phosphorus. The results of this analytical testing is presented on Table I and shows a significant decrease in the petroleum hydrocarbon I concentrations over time. Current Sampling Event Of Bioremediating Soil IThe two biocells (West and East) were divided into 11 sections each (1 through 11, spaced every 150 feet) of approximately 500 cubic yards beginning at the north end. Four (4) soil samples (A, B, C, I I 4700 DISTRICT BLVD. ' BAKERSFIELD, CALIFORNIA93313 ' PHONE (805) 831-5100 · FAX: (805) 831-2111 ! SOILS ENGINEERING. INC. I - I Soil Sa~npling Report File No. 97-8308 For Tract 5426, T30S, R27E, Sec 6, Bakersfield, California Page No. 2 I D) were collected randomly in the top 1 to 1½ feet in each section of the biocells and composited at Zalco Laboratories, Inc.. The composite soil samples were analyzed for Total Recoverable Petroleum Hydrocarbons (TRPH) by EPA Method 1664. Every Fifth composite soil sample was analyzed for I volatile organics (BTEX) by EPA Method 8020 and tbr TPH as diesel by LUFT Method. Six sets (3 from each biocell) of deeper composite samples (greater than 11/2 feet bgs.) were collected and analyzed for TRPH at every third sampling location to evaluate the deeper soil for use as backf'dl Imaterial. In total 112 soil samples were collected from the biocells and composited into 28 samples. Each soil sample was collected in a brass tube, sealed with a Teflon lined cap, labeled, and placed in iced storage prior to being transferred to Zalco Laboratories for chemical analysis under Chain-of ICustody documents. FINDINGS The majority of soil enCountered in the top 12-inches of soil within the biocells appeared'to be slightly impacted by petroleum hydrocarbons with only minor odor and no staining. This material.was predominately sand which was loose and saturated with water. Below approximately 16-inches compacted soil was encountered with moderate to strong petroleum odor and gray staining at the six deeper sample locations. This material was also predominately sand with sections of silt and clay. The analytical results for the soil samples analyzed from the biocells are presented on Table 2. The majority of composite soil samples in the top 1½ feet had analytical results below 1,000 parts per million (ppm). TPHd results ranged from 596 to 1380 ppm with no BTEX constituents reported. Sections 5W (1500 ppm TRPH) and 6E (1380 ppm TPHd) had either TRPH or TPHd results over 1000 ppm and ii' used for backfill material should be mixed with clean soil at a ratio of at least 1 (biocell) to ½ (clean soil). The analytical results of the composite soil samples from below 1½ feet, indicate that this soil has not been adequately bioremediated in at least the northern 1/3 of the biocells. If this soil is used as backfill material it would need to be mixed with clean soil at a ratio of at least 1 (clean) to 1 (biocell material). If this soil is not used as backfill material it should be further bioremediated to acceptable levels to '~' prior use. CONCLUSIONS & RECOMMENDATIONS The majority of the soil within the biocells have petroleum hydrocarbon concentrations less than 1000 ppm TRPH and can be used as backfill material in the sewer line trenches. Sections 5W and 6W of the biocells remain over 1000 ppm in the top 1½ feet and should be mixed with clean soil prior to use. The soil below 1½ feet is stained and still has petroleum odor and if used should be mixed at a ratio of 1 to 1 with clean soil. If this soil is not used as backfill material it should continue to be I SOILS ENGINEERING, INC.

During the removal of the soil t¥om the biocells subjective observations (staining and odor) should be Used to separate out the soil with gray staining and strong odor from the "cleaner" bioremediated soil that does not need to be mixed before use. The mixture of soil below 11/2 feet in th~ biocells and the clean existing soil should be sampled every 1000 cubic yards to verify TRPH concentrations less than 1000 ppm. The soil placed into the sewer line trenches should be linfited to the top 10 feet and should be covered by asphalt paved roads. The pavement will tin, it the water entry into this soil and should prevent any migration of the remaining petroleum hydrocarbons in the soil to the groundwater beneath the site. SCHEDULE OF WORK The soil within the biocells will be removed, mixed (if necessary), and placed in the sewer line trenches as backfill material and compacted. This work will begin following verbal approval of this report by the RWQC~ and th,~ FDES.

(SEI) the of soil and collected the of following receipt groundwater samples during assessment a petroleum release at the subject site. The release appears, at least in part, to have emanated from a former pipeline now removed. A Site Assessment Workplan (Workplan) dated March 6, 1997 was prepared by SEI and submitted to the Regional Water Quality Control Board (RWQCB) for review and approval. On March 7, 1997 SEI received oral approval of the Workplan from Hassan Jakhar of the RWQCB. The following report describes the field work completed between March 11, and March 18, 1997 to assess the vertical and lateral limits of soil and groundwater impacted by petroleum hydrocarbons in accordance with the approved workplan. SITE HISTORY The subject site is part of a new residential development formerly owned by Tenneco Oil Company located in Township 30 South, Range 27 East, Section 6 in Kern County (see Location Map, Plate 1). During the grading of Tract 5426 petroleum impacted soils were encountered along Cladham Common Drive between Attleboro and Maidenhead Avenues (see Plot Plan, Plate 2). The stained surface area was approximately 120 feet long by 40 feet wide. Prior to the grading of Tract 5426, a 15-inch diameter steel pipeline was removed from the subject site after being first encountered on an adjoining Tract. According to the contractor who removed the pipeline, it ran along the eastern edge of the former James Canal (parallel to Cladham Common Drive) and then angled deeper to the southwest beneath the canal at a maximum depth of approximately 20 feet below ground surface. The. area along Cladham Common Drive was the only area along the former pipeline where petroleum hydrocarbon staining was evident in the soil. See Appendix B for copy of former pipeline location provided by the State Fire Marshall.

Hand auger boring S-1 was placed near the center of the staining and S-2 and S-3 were placed 30' north and south of S-i, respectively (see Plot Plan). Soil samples were collected at 1 and 8 feet below ground surface (bgs) at each location and analyzed for Oil and Grease, and Benzene, Toluene, Ethylbenzene, and Xylenes at BC Laboratories. Soil sample S-l-1 was also analyzed for lead to evaluate metal concentrations. Petroleum odor and staining was evident in borings S-1 and S-3 from surface to 8 feet bgs. Petroleum staining and odor began at 3 feet bgs in S-2 and continued to 8 feet bgs. Analytical results of these soil samples indicate no benzene or toluene and only trace concentrations of ethylbenzene and xylenes. Oil and grease results ranged from 24 parts per million (ppm) to 15,000 ppm (S-1-8'). The analysis for lead was reported as non detect. See Table 1 and the attached analytical reports (Appendix A) for more detail. Since the base of the hydrocarbon deposition was not encountered in the hand auger borings, it was recommended by SEI to drill a minimum of one soil boring in the vicinity of the center of the oil staining to define the depth of the migration. Boring B-1 was drilled with a hollow-stem drilling rig on February 28, 1997 between hand auger borings S-1 and S-3. Petroleum staining was evident in drilling cuttings to a depth of 30 feet bgs. A soil sample was collected at 30 feet for evaluation of staining and odor, and groundwater was evident in the sample. .. A second boring (B-2) was drilled near hand auger S-2 to evaluate the vertical depth of petroleum staining in this area. Drill cutting indicated moderate petroleum staining to at least 27 feet bgs in sand and silty sand. Soil samples were collected at depths of 20 and 25 feet for analysis (oil and grease) and a groundwater sample (B2-W) was collected with a disposable bailer through the and for BTEX. A bentonite seal was placed at the bottom of each boring and augers analyzed backiilled up to grade. The soil sample from B-1 at 30 feet had 5,000 ppm oil and grease . reported and samples from B-2 at 20 and 25 feet had 5,200 and 3,700 ppm oil and grease reported, respectively. The groundwater sample collected from parts per (ppb) B-2 had 73 billion benzene and 380 ppb ethylbenzene reported. See Table 1 and Appendix A for more detail. I SOILS ENGINEERING, INC.

See Appendix E for photos of work conducted. Monitoring Well Permits Monitoring well permits for 3 monitoring wells were obtained from the Kern County Environmental Health Services Department (KCEHSD) on March 5, 1997. Copies of the monitoring well permits (#2281-28, 2282-28 and 2283-28) are presented in Appendix B. Drilling & Soil Sampling An SEI owned and operated Hollow-stem auger drill rig was utilized to advance 23 additional soil borings in the area of the suspected pipe line leak. A California registered geologist (RG) supervised the drilling process and collected all of the soil samples. Eighteen of the borings (B-3 through B-20) were drilled in the area of the suspected pipeline leak and five borings (P- 1 through P-5) were drilled along the former location of the pipeline to the north and southwest. The soil borings were drilled to a minimum depth of 20 feet bgs and a maximum of 40 feet bgs. Three of the borings (B-13, B-19 and B-20) were drilled 10 to 15 feet below the first water encountered and converted to monitoring wells. See enclosed Plot Plan for boring locations (plate 2). To define the western boundary of the soil impacted with petroleum, borings B-3 through B-7 drilled lot 13 and B-12 B-15 drilled Lot 15. To define the were on borings through were on southern edge of the impacted soil, borings B-9 through B-11 were drilled near the centerline of Cladham Common Drive. To define the northern extent of petroleum impacted soils, borings B-8 and P-4 were drilled. To define the eastern extent of petroleum impacted soil, borings B-16 through 19 were drilled. To evaluate the soil and groundwater conditions near the center of the release, boring B-20 was drilled in the center of Cladham Common Drive just north of boring B-1. Soil samples were collected with a California modified split-spoon sampler at varying intervals and evaluated in the field for petroleum hydrocarbons (staining and odor), soil type and photo- ionization detector (PID) readings. The sampler (containing four 6-inch brass tubes) was advanced into native soil approximately 2-feet at each sampling point with a sampling hammer and blow-counts were recorded for each 6-inch interval advanced. A soil sample from each sampling interval was sealed with Teflon sheeting, labeled and placed in an iced cooler. The soil samples were described by a registered geologist utilizing the Unified Soil Classification System (USCS) and logs for each boring are presented in Appendix C. The split-spoon sampler was decontaminated in soapy water and rinsed between each sampling event. Augers were steamcleaned between each boring to prevent cross-contamination.

I, Monitoring Well Completions Three of the borings (B-20, B-13 and B-19) were completed as monitoring wells (MW-l, MW- I 2, MW-3, respectively) by installing casing each boring. and 2-inch diameter schedule 40 PVC Fifteen feet of 0.020" slotted casing was installed in wells MW-2 and MW-3 with approximately 25 feet of blank casing extending to the surface. A 20 foot long screen interval (0.02") was I placed in well MW-1 with 20 feet of blank PVC casing. A sand filter pack (#2/12) was placed in the annular space between the borehole and the casing from the bottom of the boring to a minimum of 2-feet above the slotted interval. A minimum of three feet of bentonite seal was I placed above the sand pack with cement grout to the surface. Each well head is protected with a locked cap and eight-inch diameter traffic rated well box. Monitoring well construction diagrams are presented in Appendix C. I Groundwater Well Development & Sampling On March 17, 1997 SEI developed the three wells by bailing and surging a minimum of 1 1/2 volumes of water and then placing a submersible pump in the bottom of each well and pumping I Until the extracted water ran clear. A minimum of 10 casing volumes were removed from each .' well. Bailers and submersible pumps were decontaminated between each well to prevent cross- contamination. I On March 18, 1997 depth .to water measurements from the top of casing of each well was recorded to the nearest one-hundredth of a foot. Depth to water measurements ranged from i 24.89' (MW-l) to 27.65' (MW-2). The three wells were then purged of a minimum of three well volumes with a submersible pump and left to recover to at least 80% of original well volumes or at least 2 hours before sampling. The water samples were collected with new disposable bailers I lowered well retrieved with clean attached to the of the bailer. The water into the and a rope top from the bailer was then slowly decanted into the appropriate sampling jars (some with preservative) provided by a State certified analytical laboratory. For wells MW-2 and MW-3, two I 40 ml VOA's and one amber 1 quart bottle were filled. For well MW-l, two 40 VOA's, one ml amber 1 quart bottle and two 1 liter plastic bottles were filled. The bottles were labeled, chilled and transported along with a chain-of-custody document and a trip blank to BC Laboratories in I Bakersfield, California. Development and purge water are presently contained in labeled DOT approved 55-gallon drums pending analysis. The water will be appropriately disposed/recycled within 90 days of generation. I !

The results of the survey were combined with the depth of water measurements to determine the current groundwater gradient beneath the site. See Appendix D for the survey plot. Analytical Testing Selected soil samples (35) were analyzed for Oil and Grease by EPA Method 413.1. Soil samples (6) with the highest PID readings were also analyzed for benzene, toluene, ethylbenzene and xylenes (BTEX). Three soil samples were analyzed for Fuel Fingerprint to determine the source of the contamination. Two of the most stained soil samples were also analyzed for CAM 17 Metals, semi-volatile organics (EPA Method 8270), pH and Flash Point as part of a hazardous characterization of the soil. All of the groundwater samples (3) were analyzed for oil and grease and BTEX. Sample MW-1 was also analyzed for complete geochemical and CAM 17 Metals. The trip blank was analyzed for BTEX. FINDINGS Soil Impact Delineation Western Extent Based on the analytical results of soil samples collected on the westside of Cladham Common Drive it appears that the lateral extent of oil and grease above 1,000 parts per million (ppm) ends between borings B-4 and B-5, approximately 70 feet west of the center of Cladham Common Drive. Highest oil and grease concentration reported was 11,000 ppm at 15 feet bgs at B-4. No BTEX concentrations were reported in the three samples tested. Fuel-finger print analysis of sample B-3-20 indicates a mixture of crude oil (2100 ppm) and diesel fuel (2900 ppm) is present in the soil. Depth of the soil impacted with petroleum hydrocarbons appears to extend to the water table at approximately 27 feet bgs throughout the 70 foot lateral extent to the west. Visible hydrocarbon staining and odor begin at approximately 10 feet bgs at B-3 and between 15 and 20 feet bgs at B-5 (trace only). Soils encountered in the borings were predominantly silty sands (SM) with some intervals of medium sands (SP) and trace silts (ML). See cross-section grained sandy West to East, Plate 4 and boring logs in Appendix C for more detail. Northern Extent Based on the analytical results of soil samples collected on the northside of Cladham Common Drive it appears that the lateral extent of oil and grease above 1,000 parts per million ends between borings B-8 and B-2, approximately 80 feet north of boring B-1. Highest oil and grease concentration reported was 5,200 ppm at 20 feet bgs at B-2.

(SEI) is proposing the following addendum to the April 15, 1998, Disposition of Bioremediated Soil Workplan for Tract 5426 in Bakersfield, CA.. As previously approved a portion of the bioremediated soil is to be transported from the biocells and placed beneath a future asphalt parking lot at a new office complex located at the Northeast corner of Stockdale Highway & Calloway Drive (see Location Map). Once the parking lot area has been filled in with soil less than 1,000 parts per million (ppm) Total Petroleum Hydrocarbons (TPH), the remaining soil wRhin the biocells is proposed to be placed in an area east of the new office complex. The soil will either be treated or mixed to concentrations in the range of 200 ppm TPH and used as fill material or placed under a future parking lot area at TPH concentrations less than 1,000 ppm. A proposed housing development in the area of the current biocell prohibits leaving the remaining soil at its current location. The following Workplan addendum describes the work proposed at the site. Current Status Of Bioremediating Soil The top 1 to 1 1/2 feet of biocell soil is currently being moved and placed under an asphalt parking lot area at a new office complex. An estimated 15,000 cubic yards of the biocell material will be used under this asphalt parking lot. An estimated 10,000 cubic yards of biocell material will remain in the current biocell location. It is proposed that this remaining biocell soil be transported to an undeveloped area east of the new office complex to be mixed and treated to acceptable TPH levels. Average TPH concentration of the remaining soil is estimated to be 2,000 ppm (based on composite soil sample collected and analyzed on June 10, 1998) prior to mixing and treating. Groundwater in this proposed treatment area is greater than 25 feet below ground surface based on soil borings conducted at the site.

The remaining biocell soil will be mixed with available clean soil spread out to a depth of approximately 6-inches and treated to acceptable TPH concentrations. After treatment (tilling, fertilizing, and minimum watering) the soil will be left in place if in the range of 200 ppm TPH or placed under a proposed asphalt parking lot planned in the next phase of construction. Monitoring of the biocell soil will be conducted periodically to determine TPH concentrations. Composite soil samples (4 discrete samples) will be collected every 1,000 cubic yards and analyzed for Total Recoverable Petroleum Hydrocarbons (TRPH) by EPA Method 418.1 to determine TPH concentrations. Each soil sample will be collected in a brass tube, sealed with a Teflon lined cap, labeled, and placed in iced storage prior to being transferred to a State certified analytical laboratory for chemical analysis under Chain-of Custody documents.

Petroleum staining and odor begins at the surface of B1 and slopes down to approximately feet bgs at B-2 and 15 feet bgs at B-8 (trace only). Soils encountered in 8 the borings were predominantly silty sands (SM) with some intervals of medium grained sands (SP) and occasional sandy silts (ML). See cross-section North to South, Plate 5 and boring logs in Appendix C for more detail. Eastern Extent Based on the analytical results of soil samples collected on the eastside of Cladham Common Drive it appears that the lateral extent of oil and grease above 1,000 parts per million ends between borings B-16 and B-17, approximately 85 feet east of the center of Cladham Common Drive. Highest oil and grease concentration reported was 1,800 ppm at 20 feet bgs at B~16. Only trace BTEX concentrations were reported in the one sample (B-16-20') tested. Fuel-finger print analysis of sample B-16-25 indicates a mixture of diesel (470 ppm) and crude oil (420 ppm) present in the soil. Depth of the soil impacted with petroleum hydrocarbons appears to extend to the water table at approximately 27 feet bgs throughout most of the 85 foot lateral extent to the east. Staining and odor does not start until approximately 18 feet bgs at boring B-16 due to the clean soil overburden of approximately 5 feet thickness. Soils encountered in the borings were predominantly silty sands (SM) with some intervals of medium grained sands (SP) and silts (ML). See cross- -' sec~tion West to East, Plate 4 and boring logs in Appendix C for more detail. Southern Extent Based on the analytical results of soil samples collected on the southside of Cladham Common Drive it appears that the lateral extent of oil and grease above 1,000 parts per million ends between borings B-9 and B-10, approximately 65 feet south of boring B-1. Highest oil and grease concentration reported was 7,200 ppm at 23 feet bgs at B-9. No BTEX concentrations were reported in the one sample (B-9-23') tested. Fuel-finger print analysis of sample B-9-15 indicates a mixture of diesel (2100 ppm) and crude oil (2100 ppm) present in the soil. Depth of the soil impacted with petroleum hydrocarbons appears to extend to the water table at approximately 25 feet bgs throughout most of the 65 foot lateral extent to the south. Hydrocarbon staining and odor begins at the surface at B1 and slopes down to approximately 8 feet bgs at B-2 and 13 feet bgs at B-10 (trace only). .Soils encountered in the borings were predominantly silty sands (SM) with some intervals of medium grained sands (SP) and occasional sandy silts (ML). See cross-section North to South, Plate 5 and boring logs in Appendix C for more detail. Metals, semi-volatile, pH and flash point analysis of selected soil samples within the plume indicate no significant elevated readings and characterize the soil as being non-hazardous.

T30S, R27E~ Sec 6~ Bakersfield, California Page No. 7 I Pipeline Borings Visual observation of the drilling of borings P-1 through P-5 located along the former i pipeline location north and southwest of the contaminated area were all "clean" with no apparent petroleum staining or odor. This indicates that the release was limited to one general area. Groundwater Impact Delineation Groundwater Gradient The groundwater gradient was calculated by using the depth to water measurements taken I on March 18, 1997 and the surveyed top of casing elevations for each well. The gradient is approximately 0.0142'/' in the south 26 east direction. To conf'm'n the gradient, groundwater levels were again recorded on March 24, 1997 and similar results were '1 observed (0.0154'/', S29E). See plate 6 for a gradient map. Groundwater Impact I Analytical results of groundwater samples collected from the monitoring wells indicate wells MW-1 and MW-2 are impacted with oil and grease at a concentrations of 31 ppm and 8.6 ppm and benzene at a concentrations of 920 ppb and 500 ppb, respectively. Well MW-3 had no petroleum hydrocarbons reported. I To verity the original results, the three monitoring wells were again purged and sampled on March 24, 1997. The wells were analyzed for oil and grease and BTEX. In addition well MW-1 was analyzed for fuel finger printing (see enclosed chromatogram for MW-l, I Appendix A). The analytical results were similar to the original sampling round with MW- 1 reported as 66 ppm oil and grease, 990 ppb benzene, and a mixture of diesel (16 ppm) and crude oil (14 ppm). MW-2 was reported as 6 ppm oil and grease and 550 ppb I benzene. Well MW-3 had only trace xylenes reported. No free product was measured on the surface of any of the monitoring wells. I Elevated arsenic and iron were reported in the water sample from MW-1. These parameters are not associated with petroleum hydrocarbons and appear to reflect background conditions. The geochemical analysis of MW- 1 indicates no additional impact I to the groundwater quality beneath the site. SOILS ENGINEERING, INC. Assesstnent Report Retnedial Action Plan, Cladhatn Cotnmon Drive File No. 97-8144 Site & For Tract 542~ T30S, R27E, Sec 6, Bakersl~eld, California Pa,ge No. 8 CONCLUSIONS & RECOMMENDATIONS Conclusions Soil has been impacted by an apparent release of crude oil and diesel from a former pipeline at the subject site. There may be independent sources for other releases to the defined area as a result of the usage of combustion engine water pumps along the former canal. The approximate area of soil with oil and grease concentrations above 1,000 ppm is 145 feet (north-south) by 155 feet (east-west) extending to a minimum depth of 25 feet where first groundwater was encountered. Based on sampling to date, the total estimated volume of soil impacted with oil and grease over 1,000 ppm is 15,000 cubic yards. Approximately 8,000 cubic yards of clean overburden will need to be removed to gain access to the hydrocarbon impacted soil for a total amount to be removed of approximately 23,000 cubic yards, not including sloping of the sides of the excavation for safety purposes. The eastern half of lots 13 and 15 are impacted with petroleum hydrocarbons extending 60 feet east of Cladham Common Drive into the proposed park area. See Plate 3 for the approximate subsurface extent of the petroleum hydrocarbons over 1,000 ppm. The soil is characterized as non-hazardous, but could pose as a potential source of contamination to the groundwater at the present high water levels unless remediated as proposed herein. Groundwater has been impacted with petroleum hydrocarbons in the area. of wells MW-1 and MW-2 with elevated concentrations of oil and diesel and benzene (see Plate 3A. grease, reported for groundwater plume). Metal analysis indicates elevated arsenic and iron in the groundwater sample from. MW-l, which, as noted, may be background. Geochemical analyses indicate no significant impaction to the groundwater quality beneath the site at MW-1. The groundwater gradient is approximately 0.014'/' in the south 24 east direction. Well MW-3 is in the general down-gradient direction from MW-1 and is not impacted with petroleum hydrocarbons. This indicates that the extent of the groundwater impact is limited to the general area of the petroleum staining and suspected pipeline release. The groundwater encountered may be part of a localized perched zone caused by water leakage from unlined canals and general surface drainage resting on the silty soil encountered at depths of 35 feet. I Recommendations SEI recommends the removal of the soil impacted with oil and grease above 1,000 ppm in the I area of the release. The excavation's extent will be approximately 145 feet by 155 feet and 25 to 30 feet deep. This will remove the majority of the hydrocarbon impacted soil and remove the potential contaminant source to the groundwater. See the following Remedial Action Plan for the i specifics of the proposed soil removal and disposition. SEI recommends that groundwater be pumped out of the excavation during the soil removal I project to remove the majority of the groundwater impacted with petroleum hydrocarbons. The removed water will be pumped into large Baker Tanks for storage and later recycling. See the ! SOILS ENGINEERING, INC. Site Assesstnent Report & Retnedial Action Plan, Cladtmm Cotntnon Drive File No. 97-8144 For Tract 5426, T30S, R27E, Sec 6, Bakerxj~eld~ California Page No. 9 t'ollowing Remedial Action Plan for the specifics of the proposed groundwater removal and disposition. Following the removal of impacted soil and water from the excavation, the installation of additional monitoring wells (northwest and southeast of MW-1 and southwest of MW-2) and sampling of all of the monitoring wells is recommended to evaluate the subsequent groundwater conditions beneath the site. REMEDIAL ACTION PLAN Petroleum Impacted Soils Excavation Of Hydrocarbon Impacted Soils SEI proposes to remove the majority of the petroleum impacted soil by excavation with heavy equipment (excavators, graders, loaders) to 25 to 30 feet bgs. Petroleum staining and odor will be used to determine the extent of the excavation, along with previous analytical results, photo-ionization detector (PID) readings and the analytical results of sidewall and base soil samples. Once the excavations extent is apparently completed, sidewall (16) and base (12) soil samPles will be collected to confu'm the removal of the majority of the hydrocarbon impacted soil to less than 1,000 ppm oil and grease. Over excavation and resampling will occur in areas with concentrations above 1,000 ppm oil and grease reported. The soil samples be collected from the excavator bucket with will brass sleeves, sealed with Teflon lined caps, labeled and placed in a cooler with blue ice. The soil samples (28) will be analyzed for oil and grease, and 1/5 for diesel and BTEX by an on-site analytical laboratory. The sides of the excavation will be sloped to prevent cave-ins and ensure the health and safety of on-site personnel. The excavation area will be fenced off to prevent public access to the area. Backfilling and Compacting Excavation The excavation will be backfilled with "clean" borrow, "clean" overburden and imported fill from the base of the excavation to the ground surface. Compaction testing will be done to verify compaction to at least 90%. Disposition Hydrocarbon Impacted Of Soil Composite soil samples (4 individual soil samples) of the stockpiled hydrocarbon impacted soil will be collected for every $00 cubic yards and analyzed for oil and grease and TPHd. Sections of the stockpiled soil with concentrations in the range of 200 ppm'oil and grease and TPHd will be considered "clean" and used as fill material. Sections of the stockpiled soil with concentrations materially over 200 ppm oil and grease will be bioremediated to concentrations in the range of 200 ppm oil and grease and TPHd prior to being used as fill material. SOilS ENGINEERING, INC. Site Assesstnent Report & Retnedial Action Platt, Cladhatn Common Drive File No. 97-8144 For Tract 5426z T30S: R27E~ Sec 6~ BakersJ~eld~ California Page No. 10 A limited biotreatability study will be conducted on representative soil samples of the hydrocarbon impacted soil to ensure that bioremediation is possible at this site to the proposed cleanup levels. The soil will be evaluated for naturally occurring hydrocarbon degrading microbes and any toxic elements within the soil that might inhibit the degradation of the hydrocarbons. The appropriate "recipe" will be determined to ensure the right mixture of microbes, nutrients, air, and moisture are present to expedite the degradation of the hydrocarbons. If the biotreatability study is successful, the soil will be bioremediated by placing the hydrocarbon impacted soil into a biocell located on vacant land adjacent to the site. The biocell will be created by forming a 2 112 foot high soil berm around the perimeter of the biocell, placing 10 ml visqueen within the biocell draped over the soil berm. Six-inches of clean sand will be placed on the bottom of the visqueen to serve as a buffer zone between the visqueen and the hydrocarbon impacted soil. Approximately 18-inches of the hydrocarbon impacted soil will be placed upon the clean sand across the biocell. See Plate 8 for a diagram of a typical biocell. The soil within the biocell will be filled weekly, fertilized, watered and covered to promote the hydrocarbon degrading microbes within the soil. Soil samples will be collected periodically to evaluate the progress of the bioremediation process and the nutrient needs of the hydrocarbon degrading'microbes.' Inoculation of microbes into the soil within the biocell will take place if naturally occurring hydrocarbon degrading microbes are not present or effective. When composite soil samples indicate the reduction of the hydrocarbons in the soil to approximately 200 parts per million oil and grease and TPHd, the soil will be considered bioremediated and used as ~l material on or off-site. The on-site area that will be used for the biocell will be enclosed with chain link fencing for the duration of the project to prevent public access. The estimated time for the full bioremediation of the soil is 4 to 6 months. Petroleum Impacted Groundwater Groundwater Removal SEI proposes to pump groundwater out of the resulting excavation in the area of the highest groundwater contamination (MW-l). Pits will be dug approximately 5 feet deeper than the excavation and a submersible pump attached to a hose extending to the surface will be placed into the pit: Groundwater will be pumped out of the pits into large Baker tanks for storage. The excavation will be pumped down approximately 3 times or until a significant decrease in groundwater contamination is evident (odor and or analysis). 1 I I SOILS ENGINEERING, INC.

A well I abandonment will be from the Kern County Environmental Health permit acquired Services Department. I Disposition Of Groundwater The groundwater within the Baker Tanks will be sampled and analyzed for oil and grease, i TPHd and BTEX. The stored groundwater will be treated through Granular Activated Carbon (GAC) setup in series and disposed of on-site (either storm drain or used as a water source for the bioremediation project). If required, a permit will be obtained to i operate the temporary GAC groundwater treatment system. Analytical testing (BTEX) will be conducted periodically between the GAC canisters and on the effluent stream to conf'mm the removal of the hydrocarbons before release on-site. The spent GAC will be i disposed/recycled at a licensed facility following the treatment of the groundwater. Re-Installation of MW-1 & Installation of MW-4, MW-5 and MW-6 I Following the backfilling and compaction of the excavation area SEI proposes to re-install monitoring well MW-1 and place additional wells (MW-4, MW-5 and MW-6) to the northwest and southeast of well MW-1 and southwest of well MW-2. Well MW-1 will be I completed similar to the original MW-1 with 20-feet of screen interval (0.02") and a total depth of 40 feet. Proposed well MW-4 will be placed 120 feet northwest of well MW-1 with 15 feet of screen interval (0.02") and a total depth of 35 feet. Proposed well MW-5 I will be 100 feet southwest of well MW-2 with 15 feet of interval (0.02") and placed screen a total depth of 35 feet. Proposed well MW-6 will be placed 140 feet southeast of well MW-1. See Plate 7 for a well diagram and Plate 3A for proposed monitoring well locations. i Purge & Sampling Of Monitoring Wells Following the completion of the new wells, they will be fully developed by surging, bailing and pumping until the water runs clear. All of the wells will be measured for depth to I water, purged of a minimum of 3 well volumes, and sampled with a disposable bailer. Groundwater samples will be analyzed for oil and grease, TPHd and BTEX. I Subsequently, SEI proposes monitoring the groundwater wells for four (4) quarters to ensure that there is no increase in hydrocarbon concentrations in the groundwater beneath the site.

HEALTH & SAFETY All SEI employees have received the Health and Safety training required by OSHA for hazardous waste site (29 CFR 1910.120). While the and operations conducting borings excavations, personnel will be equipped with a photoionization detector with which to monitor the ak for organic vapors. Personnel are also issued ak-purifying respirators (APR) with organic vapor canisters which can be donned if conditions warrant. Petroleum hydrocarbons are the identified hazardous substances at the site. The more volatile components, especially benzene, pose the greatest relative health hazard. The permissible exposure limit for benzene is 10 ppm, which was has not been exceeded in the soil samples. Because of the outdoor location and the intermittent nature of drilling operations, it is not considered likely that personnel will be exposed to elevated levels of hydrocarbon vapors for any length of time. Under these conditions personnel will work under "Class D" protection. If odors and elevated'readings are noted on ak monitoring equipment, APRs will be put on and operations..' ..... ' suspended till site safety is evaluated. Colorimeter tubes can be used to determine the concentrations of specific contaminants in the air. The current Site-Specific Health and Safety Plan submitted with the Workplan will be utilized for this remedial activity also.

(SEI) following the receipt of soil and groundwater samples collected during the assessment of a petroleum release at the subject site. The release appears, at least in part, to have emanated from a · former pipeline now removed. A Site Assessment Workplan (Workplan) dated March 6, 1997 was prepared by SEI and submitted to the Regional Water Quality Control Board (RWQCB) for review and approval. On March 7, 1997 SEI received oral approval of the Workplan from IHassan Jakhar of the RWQCB. The following report describes the field work completed between March 11, and March 18, 1997 to assess the vertical and lateral limits of soil and groundwater impacted by petroleum hydrocarbons in accordance with the approved Workplan. I SITE HISTORY I The subject site is part of a new residential development formerly owned by Tenneco Oil Company located in Township 30 South, Range 27 East, Section 6 in Kern County (see Location Map, Plate 1). During the grading of Tract 5426 petroleum impacted soils were encountered i along Cladham Common Drive between Attleboro and Maidenhead Avenues (see Plot Plan, Plate 2). The stained surface area was approximately 120 feet long by 40 feet wide. Prior to the grading of Tract 5426, a 15-inch diameter steel pipeline was removed from the subject site after I being encountered on an adjoining According to contractor fa-st Tract. the who removed the pipeline, it ran along the eastern edge of the former James Canal (parallel to Cladham Common Drive) and then angled deeper to the southwest beneath the canal at a maximum depth of I. approximately 20 feet below ground surface. The. area along Cladham Common Drive was the only area along the former pipeline where petroleum hydrocarbon staining was evident in the soil. iSee Appendix B for copy of former pipeline location provided by the State Fire Marshall.

Hand auger boring S-1 was placed near surface the center of the staining and S-2 and S-3 were placed 30' north and south of S-I, respectively (see Plot Plan). Soil samples were collected at 1 'and 8 feet below ground surface (bgs) at each I location and analyzed for Oil and Grease, and Benzene, Toluene, Ethylbenzene, and Xylenes at BC Laboratories. Soil sample S-l-1 was also analyzed for lead to evaluate metal concentrations. .. · Petroleum odor and staining was evident in borings S-1 and S-3 from surface to 8 feet bgs. Petroleum staining and odor began at 3 feet bgs in S-2 and continued to 8 feet bgs. Analytical results of these soil samples indicate no benzene or toluene and only trace concentrations of Iethylbenzene and xylenes. Oil and grease results ranged from 24 pans per million (ppm) to 15,000 ppm (S-1-8'). The analysis for lead was reported as non detect. See Table 1 and the attached analytical reports (Appendix A) for more detail. I Since the base of the hydrocarbon deposition was not encountered in the hand auger borings, it was recommended by SEI to drill a minimum of one soil boring in the vicinity of the center of the I oil staining to define the depth of the migration. Boring B-1 was drilled with a hollow-stem drilling rig on February 28, 1997 between hand auger borings S-1 and S-3. Petroleum staining was evident in drilling cuttings to a depth of 30 feet bgs. A soil sample was collected at 30 feet I for evaluation of Staining and odor, and groundwater was evident in the sample. A second boring (B-2) was drilled near hand auger S-2 to evaluate the vertical depth of petroleum I staining in this area. Drill cutting indicated moderate petroleum staining to at least 27 feet bgs in sand and silty sand. Soil samples were collected at depths of 20 and 25 feet for analysis (oil and grease) and a groundwater sample (B2-W) was collected with a disposable bailer through the I BTEX. A bentonite seal the bottom of each and augers and analyzed for was placed at boring backfilled up to grade. The soil sample from B-1 at 30 feet had 5,000 ppm oil and grease reported and samples from B-2 at 20 and 25 feet had 5,200 and 3,700 ppm oil and grease I reported, respectively. The groundwater sample collected from B-2 had 73 parts per billion (ppb) benzene and 380 ppb ethylbenzene reported. See Table 1 and Appendix A for more detail. I I I I I SOILS ENGINEERING, INC.

See Appendix E for photos of work conducted. I Monitoring Well Permits i Monitoring well permits for 3 monitoring wells were obtained from the Kern County -,I Environmental Health Services Department (KCEHSD) on lVlarch 5, 1997. Copies of the · monitoring well permits (#2281-28, 2282-28 and 2283-28) are presented in Appendix B. I Drilling & Soil Sampling An SEI owned and operated Hollow-stem auger drill rig was utilized to advance 23 additional soil I borings in the area of the suspected pipe line leak. A Califomia registered geologist (RG) supervised the drilling process and collected all of the soil sm'nples. Eighteen of the borings (B-3 through B-20) were drilled in the area of the suspected pipeline leak and five borings (P-1 through I P-5) were drilled along the former location of the pipeline to the north and southwest. The soil borings were drilled to a minimum depth of 20 feet bgs and a maximum of 40 feet bgs. Three of the borings (B-13, B-19 and B-20) were drilled 10 to 15 feet below the fkst water encountered I and converted to wells. See enclosed Plot Plan for locations monitoring boring (plate 2). To define the western boundary of the soil impacted with petroleum, borings B-3 through B-7 I were drilled on lot 13 and borings B-12 through B-15 were drilled on Lot 15. To define the southern edge of the impacted soil, borings B-9 through B-11 were drilled near the centerline of i Cladham Common Drive. To define the northern extent of petroleum impacted soils, borings B-8 and P-4 were drilled. To define the eastern extent of petroleum impacted soil, borings B-16 through 19 were drilled. To evaluate the soil and groundwater conditions near the center of the I release, boring B-20 was drilled in the center of Cladham Common Drive just north of boring B-1. SoiI samples were collected with a California modified split-spoon sampler at varying intervals I and evaluated in the field for petroleum hydrocarbons (staining and odor), soil type and phot°- ionization detector (PID) readings. The sampler (containing four 6-inch brass tubes) was advanced into native soil approximately 2-feet at each sampling point with a Sampling hammer I and blow-counts were recorded for each 6-inch interval advanced. A soil sample from each Sampling interval was sealed with Teflon sheeting, labeled and placed in an iced cooler. The soil samples were described by a registered geologist utilizing the Unified Soil Classification System I (USCS) and logs for each boring are presented in Appendix C. The split-spoon sampler was decontaminated in soapy water and rinsed between each sampling I event, steamcleaned between each boring to cross-contamination.

I Monitoring Well Completions i Three of the borings (B-20, B-13 and B-19)were completed as monitoring wells (MW-l, MW- 2, and MW-3, respectively) by installing 2-inch diameter schedule 40 PVC casing in each boring. Fifteen feet of 0.020" slotted casing was installed in wells M~V-2 and MW-3 with approximately I25 feet of blank casing extending to the surface. A 20 foot long screen interval (0.02") was placed in well MW-1 with 20 feet of blank PVC casing. A sand filter pack (#2/12) was placed in the annular space between the borehole and the casing from the bottom of the boring to a minimum of 2-feet above the slotted interval. A minimum of three feet of bentonite seal was placed above the sand pack with cement grout to the surface. Each well head is protected with a locked cap and eight-inch diameter traffic rated well box. Monitoring well construction diagrams Iare presented in Appendix C. I Groundwater Well Development & Sampling On March 17, 1997 SEI developed the three wells by bailing and surging a minimum of 1 1/2 volumes of water and then placing a submersible pump in the bottom of each well and pumping IUntil the extracted water ran clear. A minimum of 10 casing volumes were removed from each well. Bailers and submersible pumps were decontaminated between each Well to prevent cross- contamination. ! On March 18, 1997 depth to water measurements from the top of casing of each well was recorded to the nearest one-hundredth of a foot. Depth to water measurements ranged from I 24.89' (MW-l) to 27.65' (MW-2). The three wells were then purged of a minimum of three well volumes with a submersible pump and left to recover to at least 80% of original well volumes or i at least 2 hours before sampling. The water samples were collected with new disposable bailers lowered into the well and retrieved with a clean rope attached to the top of the bailer. The water from. the bailer was then slowly decanted into the appropriate sampling jars (some with preservative) provided by a State certified analytical laboratory. For wells MW-2 and MW-3, tWo 40 ml VOA's and one amber 1 quart bottle were filled. For well MW-1, two 40 ml VOA's, one amber 1 quart bottle and two 1 liter plastic bottles were filled. The bottles were labeled, chilled I and transported along with a chain-of-custody document and a trip blank to BC Laboratories in Bakersfield, California. IDevelopment and purge water are presently contained in labeled DOT approved 55-gallon drums pending analysis. The water will be appropriately disposed/recycled within 90 days of generation. 1 I SOILS ENGINEERING, INC.

The results of the survey were combined with the depth of water measurements to determine the current groundwater gradient beneath the site. See Appendix D for the survey plot. Analytical Testing Selected soil samples (35) were analyzed for Oil and Grease by EPA Method 413.1. Soil samples (6) with the highest PID readings were also analyzed for benzene, toluene, ethylbenzene and xylenes (BTEX). Three soil samples were analyzed for Fuel Fingerprint to determine the source of the contamination. Two of the most stained soil samples were also analyzed for CAM 17 Metals, semi-volatile organics (EPA Method 8270), pH and Flash Point as part of a hazardous characterization of the soil. Ail of the groundwater samples (3) were analyzed for oil and grease and BTEX. Sample MW-1 was also analyzed for complete geochemical and CAM 17 Metals. The trip blank was analyzed t'or BTEX. FINDINGS Soil Impact Delineation Western Extent Based on the analytical results of soil samples collected on the westside of Cladham Common Drive it appears that the lateral extent of oil and grease above 1,000 parts per million (ppm) ends between borings B-4 and B-5, approximately 70 feet west of the center of Cladham Common Drive. Highest oil and grease concentration reported was 11,000 ppm at 15 feet bgs at B-4. No BTEX concentrations were reported in the three samples tested. Fuel-finger print analysis of sample B-3-20 indicates a mixture of crude oil (2100 ppm) and diesel fuel (2900 ppm) is present in the soil. Depth of the soil impacted with petroleum hydrocarbons appears to extend to the water table at approximately 27 feet bgs the 70 foot lateral to the west. Visible staining and odor throughout extent hydrocarbon begin at approximately 10 feet bgs at B-3 and between 15 and 20 feet bgs at B-5 (trace only). Soils encountered in the borings were predominantly silty sands (SM) with some intervals of medium grained sands (SP) and trace sandy silts (ML). See cross-section West to East, Plate 4 and boring logs in Appendix C for more detail. Northern Extent Based on the analytical results of soil samples collected on the northside of Cladham Common Drive it appears that the lateral extent of oil and grease above 1,000 parts per million ends between borings B-8 and B-2, approximately 80 feet north of boring B-1. Highest oil and grease concentration reported was 5,200 ppm at 20 feet bgs at B-2. I I SOILS ENGINEERING, INC.

I Eastern Extent Based on the analytical results of soil samples collected on the eastside of Cladham Common Drive it appears that the lateral extent of oil and grease above 1,000 parts per I million ends between borings B-16 and B-17, approximately 85 feet east of the center of Cladham Common Drive. Highest oil and grease concentration reported was 1,800 ppm at 20 feet bgs at B-16. Only trace BTEX concentrations were reported in the one sample I (B-16-20') tested. Fuel-finger print analysis of sample B-16-25 indicates a mixture of diesel (470 ppm) and crude oil (420 ppm) present in the soil. Depth of the soil impacted with petroleum hydrocarbons appears to extend to the water table at approximately 27 I feet bgs throughout most of the 85 foot lateral extent to the east. Staining and odor does not start until approximately 18 feet bgs at boring B-16 due to the clean soil overburden of approximately 5 feet thickness. Soils encountered in the borings were predominantly silty I sands (SM) with intervals of medium grained sands (SP) and silts (ML). See cross- some section West to East, Plate 4 and boring logs in Appendix C for more detail. I Southern Extent Based on the analytical results of soil samples collected on the southside of Cladham i Common Drive it appears that the lateral extent of oil and grease above 1,000 parts per million ends between borings B-9 and B-10, approximately 65 feet south of boring B-1. Highest oil and grease concentration reported was 7,200 ppm at 23 feet bgs at B-9. No I BTEX concentrations were reported in the one sample (B-9-23') tested.

T30S, R27Ez Sec 6~ Bakersfield., California Page No. 7 I Pipeline Borings Visual observation of the drilling of borings P-1 through P-5 located along the former i pipeline location north and southwest of the contaminated area were all "clean" with no apparent petroleum staining or odor. This indicates that the release was limited to one general area. i Groundwater ImPact Delineation I Groundwater Gradient The groundwater gradient was calculated by using the depth to water measurements taken I on March 18, 1997 and the surveyed top of casing elevations for each well. The gradient is approximately 0.0142'/' in the south 26 east direction. To confirrn the gradient, groundwater levels were again recorded on March 24, 1997 and similar results were I observed (0.0154'/', S29E). See plate 6 for a gradient map. Groundwater Impact I' Analytical results of groundwater samples collected from the monitoring wells indicate wells MW-1 and MW-2 are impacted with oil and grease at a concentrations of 31 ppm and 8.6 ppm and benzene at a concentrations of 920 ppb and 500 ppb, respectively. Well i MW-3 had no petroleum hydrocarbons reported. To verify the original results, the three monitoring wells were again purged and sampled on March 24, 1997. The wells were analyzed for oil and grease and BTEX. In addition well MW-1 was analyzed for fuel finger printing (see enclosed chromatogram for MW-l, Appendix A). The analytical results were similar to the original sampling round with MW- 1 reported as 66 ppm oil and grease, 990 ppb benzene, and a mixture of diesel (16 ppm) and crude oil (14 ppm). MW-2 was reported as 6 ppm oil and grease and 550 ppb benzene. Well MW-3 had only trace xylenes reported. No free product was measured on the surface of any of the monitoring wells. Elevated arsenic iron were reported water sample and the from MW-1. These parameters are not associated with petroleum hydrocarbons and appear to reflect background conditions. The geochemical analysis of MW-1 indicates no additional impact to the groundwater quality beneath the site. I I I I I SOILS ENGINEERING, INC. I Site Assesstnent Report & Retnedial Action Plan, Cladham Cotnmon Drive File No. 97-8144 For Tract 5426~ T30S, R27E, Sec 6~ Bakersfield, California Page No. 8 I CONCLUSIONS & RECOMMENDATIONS Conclusions Soil has been impacted by an apparent release of crude oil and diesel from a former pipeline at the i subject site. There may be independent sources for other releases to the defined area as a result of the usage of combustion engine water pumps along the former canal. The approximate area of soil with oil and grease concentrations above 1,000 ppm is 145 feet (north-south) by 155 feet I (east-west) extending to a minimum depth of 25 feet where first groundwater was encountered. Based on sampling to date, the total estimated volume of soil impacted with oil and grease over 1,000 ppm is 15,000 cubic yards. Approximately 8,000 cubic yards of clean overburden will need to be removed to gain access to the hydrocarbon impacted soil tbr a total amount to be removed of approximately 23,000 cubic yards, not including sloping of the sides of the excavation for safety purposes. The eastern half of lots 13 and 15 are impacted with petroleum hydrocarbons I extending 60 feet east of Cladham Common Drive into the proposed park area. See Plate 3 for the approximate subsurface extent of the petroleum hydrocarbons over 1,000 ppm. The soil is characterized as non-hazardous, but could pose as a potential source of contamination to the I groundwater at the present high water levels unless remediated as proposed herein. Groundwater has been impacted with petroleum hydrocarbons in the area of wells MW-1 and I with elevated concentrations of oil and grease, reported (see MW-2 diesel and benzene Plate 3A. for groundwater plume). Metal analysis indicates elevated arsenic and iron in the groundwater sample from MW-l, which, as noted, may be background. Geochemical analyses indicate no I significant impaction to the groundwater quality beneath the site at MW-1. The groundwater gradient is approximately 0.014'/' in the south 24 east direction. Well MW-3 is in the general idown-gradient direction from MW-1 and is not impacted with petroleum hydrocarbons. This indicates that the extent of the groundwater impact is limited to the general area of the petroleum staining and suspected pipeline release. The groundwater encountered may be part of a localized perched zone caused by water leakage from unlined canals and general surface drainage resting on · the silty soil encountered at depths of 35 feet. I Recommendations SEI recommends the removal of the soil impacted with oil and grease above 1,000 ppm in the I area of the release. The excavation's extent will be approximately 145 feet by 155 feet and 25 to 30 feet deep. This will remove the majority of the hydrocarbon impacted soil and remove the potential contaminant source to the groundwater. See the following Remedial Action Plan for the I specifics of the proposed disposition. soil removal and i SEI recommends that groundwater be pumped out of the excavation during the soil removal project to remove the majority of the groundwater impacted with petroleum hydrocarbons. The removed water will be pumped into large Baker Tanks for storage and later recycling. See the I I I-_ SOILS ENGINEERING, INC. I Site Assesstnent Report & Remedial Action Plan, Cladham Cotmnon Drive File No. 97-8144 For Tract 5426, T30S, R27E, Sec 6. Bakersfield, California Page No. 9 I following Remedial Action Plan for the specifics of the proposed groundwater removal and disposition. Following the removal of impacted soil and water from the excavation, the installation 'of additional monitoring wells (northwest and southeast of MW-1 and southwest of IMW-2) and sampling of all of the monitoring wells is recommended to evaluate the subsequent groundwater conditions beneath the site. i REMEDIAL ACTION PLAN I Petroleum Impacted Soils I Excavation Of Hydrocarbon Impacted Soils SEI proposes to remove the majority of the petroleum impacted soil by excavation with heavy equipment (excavators, graders, loaders) to 25 to 30 feet bgs. Petroleum staining I and odor will be used to determine the extent of the excavation, along with previous analytical results, photo-ionization detector (PID) readings and the analytical results of sidewall and base soil samples. Once the excavations extent is apparently completed, i sidewall (16) and base (12) soil samples will be collected to confirm the removal of the majority of the hydrocarbon impacted soil to less than 1,000 ppm oil and grease. Over excavation and resampling will occur in areas with concentrations above 1;000 ppm oil I and The soil will be collected from 'the bucket with grease reported. samples excavator brass sleeves, sealed with Teflon lined caps, labeled and placed in a cooler with blue ice. The soil samples (28) will be analyzed for oil and grease, and 1/5 for diesel and BTEX by I an on-site analytical laboratory. i The sides of the excavation will be sloped to prevent cave-ins and ensure the health and safety of on-site personnel. The excavation area will be fenced off to prevent public access to the area. I Backfilling and Compacting Excavation The excavation will be backfilled with "clean" borrow, "clean" overburden and imported I fill from the base of the excavation to the ground surface. Compaction testing will be done to verify compaction to at least 90%. I Disposition Of Hydrocarbon Impacted Soil Composite soil samples (4 individual soil samples) of the stockpiled hydrocarbon impacted soil will be collected for every 500 cubic yards and analyzed for oil and grease and TPHd. I Sections of the stockpiled soil with concentrations in the range of 200 ppm' oil and grease and TPHd will be considered "clean" and used as fill material. Sections of the stockpiled i soil with concentrations materially over 200 ppm oil and grease will be bioremediated to concentrations in the range of 200 ppm oil and grease and TPHd prior to being used as fill material. i I I SOILS ENGINEERING.

I Site Assesstnent Report & RemedialAction Plan, Cladhatn Common Drive File No. 97-8144 For Tract 5426~ T30S, R27E: Sec 6~ Bakersfield~ California Page No. 10 A limited biotreatability study will be conducted on representative soil samples of the hydrocarbon impacted soil to ensure that bioremediation is possible at this site to the proposed cleanup levels. The soil will be evaluated t'or naturally occurring hydrocarbon I degrading microbes and any toxic elementS within the soil that might inhibit the degradation of the hydrocarbons. The appropriate "recipe" will be determined to ensure the right mixture of microbes, nutrientS, air, and moisture are present to expedite the I degradation of the hydrocarbons. If the biotreatability study is successful, the soil will be bioremediated by placing the i soil into biocell located land the site. The hydrocarbon impacted a on vacant adjacent to biocell will be created by forming a 2 1/2 foot high soil berm around the perimeter of the biocell, placing 10 ml visqueen within the biocelI draped over the soil berm. Six-inches of I clean sand will be placed on the bottom of the visqueen to serve as a buffer zone between the visqueen and the hydrocarbon impacted soil. Approximately 18-inches of the hydrocarbon impacted soil will be placed upon the clean sand across the biocell. See Plate I 8 for a diagram of a typical biocell. I The soil within the biocell will be tilled weekly, fertilized, watered and covered to promote the hydrocarbon degrading microbes within the soil. Soil samples will be collected periodically to evaluate the progress of the bioremediation process and the nutrient needs I of the hydrocarbon degrading 'microbes. Inoculation of microbes into the soil within the biocell will take place if naturally occurring hydrocarbon degrading microbes are not present or effective. When composite soil samples indicate the reduction of the I hydrocarbons in the soil to approximately 200 parts per million oil and grease and TPHd, the soil will be considered bioremediated and used as fill material on or off-site. i The on-site that will be used for the biocell will be enclosed with chain link fencing area for the duration of the project to prevent public access. The estimated time for the full i bioremediation of the soil is 4 to 6 months. I Petroleum Impacted Groundwater Groundwater Removal I SEI proposes to pump groundwater out of the resulting excavation in the area of the highest groundwater contamination (MW-l). PitS will be dug approximately 5 feet deeper than the excavation and a submersible pump attached to a hose extending to the surface i will be placed into the pit: Groundwater will be pumped out of the pits into large Baker · tanks for storage. The excavation will be pumped down approximately 3 times or until a significant decrease in groundwater contamination is evident (odor and or analysis). I I I I SOILS ENGINEERING, INc.

A well I abandonment permit will be acquired from the Kern County Environmental Health Services Department. i Disposition Of Groundwater The groundwater within the Baker Tanks will be sampled and analyzed for oil and grease, · · TPHd and BTEX. The stored groundwater will be treated through Granular Activated I Carbon (GAC) setup in series and disposed of on-site (either storm drain or used as a water source for the bioremediation project). If required, a permit will be obtained to operate the temporary GAC groundwater treatment system. Analytical testing (BTEX) will be conducted periodically between the GAC canisters and on the effluent stream to conf'mm the removal of the hydrocarbons before release on-site. The spent GAC will be I disposed/recycled at a licensed facility following the treatment of the groundwater. Re-Installation of MW-1 & Installation of MW-4, MW-5 and MW-6 I Following the backfilling and compaction of the excavation area SEI proposes to re-install monitoring well MW-1 and place additional wells (MW-4, MW-5 and MW-6) to the northwest and sOutheast of well MW-1 and southwest of well MW-2: Well IvlW-1 will be I completed similar to the original MW-1 with 20-feet of screen interval (0.02") and a .total depth of 40 feet. Proposed well MW-4 will be placed 120 feet northwest of well MW-1 with 15 feet of screen interval (0.02") and a total depth of 35 feet. Proposed well MW-5 I will be 100 feet southwest of well MW-2 with 15 feet of placed screen interval (0.02") and a total depth of 35 feet. Proposed well MW-6 will be placed 140 feet southeast of well MW-1. See Plate 7 for a well diagram and Plate 3A for proposed monitoring well I locations. I Purge & Sampling Of Monitoring Wells Following the completion of the new wells, they will be fully developed by surging, bailing and pumping until the water runs clear. All of the wells will be measured for depth to i water, purged of a minimum of 3 well volumes, and sampled with a disposable bailerl Groundwater samples will be analyzed for oil and grease, TPHd and BTEX. I Subsequently, SEI proposes monitoring the groundwater wells for four (4) quarters to ensure that there is no increase in hydrocarbon concentrations in the groundwater beneath the site.

HEALTH & SAFETY All SEI employees have received the Health and Safety training required, by OSHA for hazardous waste site operations (29 CFR 1910.120). While conducting the borings and excavations, personnel will be equipped with a photoionization detector with which to monitor the air for organic vapors. Personnel are also issued air-purifying respirators (APR) with organic vapor canisters which can be donned if conditions warrant. Petroleum hydrocarbons are the identified hazardous substances at the site. The more volatile components, especially benzene, pose the greatest relative health hazard. The permissible exposure limit for benzene is 10 ppm, which was has not been exceeded in the soil samples. Because of the outdoor location and the intermittent nature of drilling operations, it is not considered likely that personnel will be exposed to elevated levels of hydrocarbon vapors for any length of time. Under these conditions personnel will work under "Class D" protection. If odors and elevated readings are noted on air monitoring equipment, APRs will be put on and operations .... suspended till site safety is evaluated. Colorimeter tubes can be used to determine the concentrations of specific contaminants in the air. The current Site-Specific Health and Safety Plan submitted with the Workplan will be utilized for this remedial activity also. i WORK SCHEDULE SEI will start work within two weeks of the submittal of this Remedial Action Plan and the I majority of the field work is estimated to be completed within 8 weeks.
