(SEI) ks notifying the Regional Water Quality Control Board (RWQCB) that six (6) monitoring wells at Tract 5426 in Bakersfield, CA. (site) have been abandoned (see Plate 1 for Location Map). The 6 monitoring wells (MW-lA, MW-2A, MW-4, MW-5, MW-6A and MW- 6B) were abandoned on September 10, 1999 in accordance with Kern County Environmental Health Services Department (KCEHSD) regulations and well abandonment permits (see attached permit). The 6 monitoring wells were abandoned by filling the PVC well casings with bentonite chips to a depth just above the depth to groundwater (30' to 42') and then filling the remaining well casing and borehole annulus with neat cement to the surface. The top 3' to 5' of each well was then drilled out and the well boxes were removed. The top 3' to 5' was then backfilled with clean soil to match existing surfaces. See Plate 2 for Plot Plan with the abandoned well locations. If you have any questions concerning this contact SEI at (661) 831-5100. RobertJ.

Rojas, Public Works Director /// FROM: Ralph E. Huey, Director, Office of Environmental Services SUBJECT: Castle and Cooke Bioremediated Soil Plan Raul, I have received your memo to Castle & Cooke concerning their work plan from Soils Engineering Inc. for the use of bioremediated soils. You, of course, have the right to determine what soils can be used on City projects. However, you need to know that your value of 200 ppm is very arbitrary and, without any technical support. If pressed, this office would have difficulty supporting a 200 ppm level. SOILS ENGINEERING, INC. May 5, 1998 Mr. Raul M. Rojas City Of Bakersfield Public Works Department $?~'1/'"~O 1501 Tmxtun Avenue ~/4)' 0 ~ Bakersfield, CA 93301 ~'hIPlt~Ol'~ ~i~~~ Subject: Amended Plan of Action For Bioremediated Soil SE/? Tract 5426 Cladham Common Drive Bakersfield, California Mr. Rojas: This Amended Plan of Action (Workplan) is submitted 'for approval by Soils Engineering, Inc. (SEI) following the receipt of a letter from the City of Bakersfield Public Works Department (PWD) dated April 27, 1998, which stated that the April 22, 1998 Plan of Action was not acceptable. This Amended Workplan for the bioremediating soil.from Tract 5426 states that: only soil with Total Petroleum Hydrocarbons (TPH) concentrations of 200 ppm and less will be used as backfill material; biocell soil will not be mixed with clean fill to attain 200 ppm TPH; soil samples will not be mixed prior to analysis; and samples will be collected and analyzed every 100 cubic yards of biocell soil. Also inCluded are the results of the most recent sampling of the biocells conducted on April 22, 1998. Attached are Location and Plot Plan maps showing the site. Top 1 Foot Of Biocells On April 22, 1998, composite soil samples (4 discreet samples mixed into 1 at the lab) were collected for every 1,000 cubic yards of soil (10 sections) in the top 1 foot of the biocells and analyzed for TPH by EPA Method 418. I. The analytical results ranged from 170 to 1300 ppm TPH. A background sample (BKGD- 1') was also collected approximately 150' east of the biocells with no TPH reported. A composite soil sample from the 2 foot level of section D East was also collected and had 3900 ppm TPH reported. See Plate 3 for sample locations and Table 2 and attached analytical reports for complete analytical data. Based on these recent analytical results only section B West had TPH less than 200 ppm. Additional discreet samples (no composites) of the biocell soil collected and analyzed every 100 cubic yards will be necessary to verify TPH concentrations of 200 ppm or less prior to use as backfill material anywhere on Tracts 5876, 5877 and 5426, including City of Bakersfield right of way areas after receiving PWD approval of this Workplan. 4700 DISTRICT BLVD. ° BAKERSFIELD, CALIFORNIA93313 · PHONE(805) 831-5100 ° FAX:(805) 831-2111 ~ '~ ~ILS ENGINEERING, INC. Amended Plan Of Action Bioremediation Of Soil File No. 97-8308 For Tract 5426, T30S, R27E, Sec 6, Bakersfield, California Page No. 2 Biocell areas with TPH concentrations above 200 ppm TPH will be further bioremediated to concentrations of 200 ppm TPH or less prior to being used as backfill material. Discreet soil samples will be collected every 100 cubic yards of biocell soil and analyzed for TPH by EPA Method 418.1 to confirm TPH concentrations. Biocell soil will not be mixed with clean fill to attain 200 ppm TPH. Once approved, SEI personnel will supervise the distribution of the biocell material less than 200 ppm TPH to ensure soil with staining and significant odor is not mistakenly used as backfill material. Bottom 2 Feet Of Biocells Once the top 1 foot of biocell soil is removed and used as fill material, the following plan is recommended: 1) Water soluble fertilizer such as ammonia nitrite should be applied to the next level of biocell soil. 2) The next level of biocell soil should be tilled thoroughly to a depth of at least 12 "and evenly spread throughout the remaining biocell area. 3) Periodic watering of the biocells should be conducted either by a water truck or a sprinkler system to keep the soil moist. 4) Daily tilling of the biocell soil should be conducted to provide maximum aeration, fertilizer and moisture content. 5) When staining and odor has been reduced significantly in this lift, soil samples should be collected every 100 cubic yards and analyzed for TPH by EPA Method 418.1 or equivalent. Areas of the biocell with TPH concentrations of 200 ppm or less will be removed and used as backf'fll material anywhere on Tracts 5876, 5877, and 5426, including City of Bakersfield right of ways. Biocell areas with TPH concentrations above 200 ppm will be further bioremediated to concentrations of 200 ppm TPH prior to removal. 6) After the removal of the second level of biocell soil, the remaining ~A to 1 foot of soil will be treated as above, until TPH concentrations are 200 ppm or less prior to removal. 7) If time constraints do not permit the bioremediation process to mn it's course, then the biocell material may be transported to an alternate Castle & Cooke California, Inc. site to be placed in the top 5 feet bgs. under an asphalt sealed parking lot (if approved by all appropriate agency's).

April 22, 1998 Mr. Raoul Rojas City Of Bakersfield Public Works Department 1501 Tmxtun Avenue Bakersfield, CA 93301 Subject: Plan of Action For Bioremediated Soil Tract 5426 Cladham Common Drive Bakersfield, California Mr. Rojas: This Plan of Action is submitted for approval by Soils Engineering, Inc. (SEI) following the verbal acceptance of the bioCell soil from Tract 5426 with Total Petroleum Hydrocarbons (TPH) concentrations in the range of 200 ppm by the City of Bakersfield Public Works Department (PWD). Attached are Location and Plot Plan maps showing the site. Top 1 Foot Of Biocelis Recent sampling of the bioremediating soil in the two biocelis has shown TPH concentrations ranging from <50 to 1970 ppm (see Plate 3). The majority of the top 1 foot of soil was less than 500 ppm TPH in February, 1998 and below 400 ppm on April 3, 1998 (see Tables 1 & 2). It is recommended that composite soil samples (4 discreet samples mixed into 1 at the lab) be collected every 1,000 cubic yards in the top 1 foot of the biocells and analyzed for TPH by EPA Method 418.1 or equivalent. Biocell areas with TPH concentrations in the range of 200 ppm will be used as backfill material anywhere on Tracts 5876, 5877 and 5426, including City of Bakersfield right of way areas as previously approved by the Regional Water Quality Control Board (RWQCB), and the City of Bakersfield Fire Department Environmental Services (COBFDES). Biocell areas with TPH concentrations above the range of 200 ppm TPH will be further bioremediated to concentrations in the range of 200 ppm TPH. SEI personnel will supervise the distribution of the biocell material to ensure soil with staining and significant odor is not used as backfill material. Bottom 2 Feet Of Biocells Once the top 1 foot of biocell soil is removed and used as fill material, the following plan is recommended: 4700 DISTRICT BLVD. ° BAKERSFIELD, CALIFORNIA93313 ° PHONE (805) 831-5100 ° FAX: (805) 831-2111 S~ILS ENGINEERING, INC. Plan Of Action Bioremediation Of Soil File No. 97-8308 For Tract 5426, T30S, R27E, Sec 6~ Bakersfleld~ California Page No. 2 1) FertiliTer should be applied to the next level of biocell soil. 2) The next level of biocell soil should be tilled thoroughly to a depth of at least 12 "and evenly spread throughout the remaining biocell area. 3) Periodic watering of the biocells should be conducted either by a water truck or a sprinkler system to keep the soil moist. 4) Daily tilling of the biocell soil should be conducted to provide maximum aeration, fertilizer and moisture content. 5) When staining and odor has been reduced significantly in this lift, soil samples should be collected every 1,000 cubic yards and analyzed for TPH. Areas of the biocell with TPH concentrations in the range of 200 ppm will be removed and used as backfill material anywhere on Tracts 5876, 5877, and 5426, including City of Bakersfield right of ways. Biocell areas with TPH concentrations above the range of 200 ppm will be further bioremediated to concentrations in the range of 200 ppm TPH prior to removal. 6) After the removal of the sec~)nd level of biocell soil, the remaining ~A to 1 foot of soil will be treated as above, until TPH concentrations are in the range of 200 ppm prior to removal. 7) If time constraints do not permit the bioremediation process to mn it's course, then the biocell material may be transported to an alternate site to be placed in the top 5 feet bgs. under an asphalt sealed parking lot (if approved by all appropriate agency's).

April 15, 1998 Regional Water Quality Control Board 3614 East Ashlan Avenue Fresno, CA 93726 Attn.: Hassan Jakhar Subject: Disposition Of Bioremediated Soil Tract 5426 Cladham Common Drive Bakersfield, California Soils Engineering, Inc. (SED is proposing to transport a portion t~f the soil from the biocells and place the material beneath a future asphalt parking lot at a new office complex located at the NbrtheaSt corner of Stockdale Highway & Calloway Drive (see Location Map). The soil frOm the bioCei~'~ be placed at a maximum depth of 5 feet below grade and covered with asphalt to'prevent' W. ater infiltration. The following Workplan describes the work proposed at the site. ~ :~. Recent Sampling Events Of Bioremediating Soil Two sampling events were conducted recently at the biocells. On April 3, 1998,'CompOsit'6..s0il samples (4 discrete samples) were collected at 6 locations and analyzed for Total PetroleUm Hydrocarbons (TPH) by EPA Method 1664 (see Plate 3 for sample locations). Selected soil were also analyzed for TPH as diesel (TPHd) by LUFf Method. Three composite sets were Coliec"ted from a depth greater than 11/o feet bgs. and three sets from the top 1 ¼ feet. In total 24 soil'sam~i6s were collected from the bioCells and composited into 6 samples. Each soil'sample was collected in a brass tube, sealed with a 'Teflon lined cap, labeled, and placed in iced storage prior to'b~ing transferred to Zalco Laboratories for chemical analysis under Chain-of Custody documents. '.The analytical results ranged from <50 to 410 ppm TPH and 495 to 1970 ppm TPHd. See Table 1 & 2 for complete analytical results and the attached analytical reports for more detail. Overall the TPH concentrations were reduced considerably from the last sampling event in February, 1998. Staining and odor were still evident in the majority of the soil below 1 1/2 feet in the biocells. A portion of the biocell material from the southern section of the eastern biocell was removed, mixed and placed in the sewer line trenches. On April 9, 1998, SEI collected three composite soil samples from 2 to 3 feet below ground surface within the sewer line trenches that had been compacted with the biocell material The three composite soil samples (SL-1, SL-2 and SL-3) were analyzed for.TP~H and sample SL-2 for TPH as diesel at Zalco Laboratories. The analytical results ranged from 400 4700 DISTRICT BLVD. · BAKERSFIELD, CALIFORNIA93313 · PHONE (805) 831-5100 ' FAX: (805) 831-2111 SOILS ENGINEERING, INC.

April 15, 1998 Regional Water Quality Control Board 3614 East Ashlan Avenue Fresno, CA 93726 Attn.: Hassan ]akhar Subject: Disposition Of Bioremediated Soft Tract 5426 Chdham Common Drive Bakersfield, California Soils Engineering, inc. (SED is proposing to transport a portion of the soil from the biocells and place the material beneath a future asphalt parking lot at a new office complex located at the Northeast corner of Stockdale Highway & Calloway Drive (see Location Map). The soil from the bioceil will be placed at a maximum depth of 5 feet below grade and coveted with asphalt to prevent water in.filtration. The following Worlcplan describes the work proposed at the site. Recent Sampling Events Of Bloremediating Soil Two sampling events were conducted recently at the biocells. On April 3, 1998, composite soil samples (4 discrete samples) were collected at 6 locations and analyzed for Total Petroleum Hydrocarbons (TPH) by EPA Method 1664 (see Plate 3 for sample locations). Selected soil samples were also analyzed for TPH as diesel (TPHd) by LUFT Method. Three composite sets were co]lected from a depth greater than 1 ~,6 feet bgs. and three sets from the top 1 ~6 feet. In total 24 soil samples were collected from the biocells and composited into 6 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 Custody documents. The analytical results ranged from <50 to 410 ppm TPH and 495 to 1970 ppm TPHd. See Table 1 & 2 for complete analytical results and the attached analytical reports for more detail. Overall the TPH concentrations were reduced considerably from the last sampling event in February, 1998. Staining and odor were still evident in the majority of the soil below 1 1/2 feet in the bioceLls. A portion of the bioceI1 material from the southern section of the eastern biocell was removed, mixed and placed in the sewer line trenches. On April 9, 1998, SEI collected three composite soil samples from 2 to 3 feet below ground surface within the sewer line trenches that had been compacted with the b~ocell material. The three composite soil samples (SD-l, SL-2 and SL-3) were analyzed for TPH and sample SL,-2 for TPH as diesel at Zalco Laboratories. The analytical results ranged from 400 4700 DISTRICT BLVD, · BAKERSFIELD, CALIFORNIA 93313 ° PHONE (805) 831-5100 · FAX: (805) 831-2111 805-831-2111 SOILS ENGINEERING 039 P03 APR 15 '98 15:57 ~ILS ENGINEERING, INC.

See Table 1 and 2 for complete analytical results. Field Work Proposed The City of Bakersfield Public Works Departmem has recently objected to the use of the biocell material in the City of Bakersfield right of way, even though the Total Petroleum Hydrocarbon (TPH) concentrations are less than 1,000 ppm. As an alternative, SEI proposes to use the biocell material as follows: The top 1 foot of soil within the biocells which have TPH concentrations is the range of 200 ppm will be removed from the biocells and used as backfill material anywhere on the neighboring Tracts 5426, 5876 and 5877 per prior approvals. The middle section of soil between 1 foot and 2 foot below grade within the biocells will be removed and mixed with clean fill to concentrations in the range of 9_00 ppm TPH and used as backfill material anywhere on Tracts 5426, 5876 and 5877 per prior approvals. The bottom 1t3 of the biocells with gray hydrocarbon staining and moderate hydrocarbon odor will be mixed to concentrations less than 1,000 ppm TPH., transported and placed under the proposed asphalt paved parking lot at Castle & Cooke Commercial's new office location at the northeast comer of Stockdale Highway & Calloway Drive, approximately ¥: mile to the northeast. The biocell soil will be limited to the top 5 feet below grade and covered by a minimum of 2- inches of low-permeable asphalt. This will prevent water infiltration from the surface and provide a minimum of 10 feet between the biocell soil and the groundwater beneath the site. Composite soil samples (combination of 4 discrete samples) will be collected for every 1,000 cubic yards of biocell soil and analyzed for TPH to confirm the proposed TPH concentrations after mixing and placement. An SEI representative will be on-site to monitor the removal and placement efforts. SCHEDULE OF WORK The soil within the biocells will be removed, mixed (if necessary), and used as backfill material or phced under an asphalt paved parking lot. This work will begin following verbal approval of this plan by the RWQCB and the City of Bakersfield Fire Department Environmental Services, 805-851-2111 SOILS ENGINEERING 059 P04 APR 15 '98 15:58 SOILS ENGINEERING, INC.

I understand your concerns regarding the use of the bioremediated soil at the' above referenced ' :: :: project. I apOlogize for not being aware of Public Works particular approvals concerning the Use . First, the source' of the petroleum impacted soil was frOm a former Tenneco Oil Company pipeline. Federal law specifically excludes fluids associated with oil production from ever being considered "hazardous waste" (40 CFR 261.4(b)(5)). ' Secondly, the petroleum impacted soil being aPproved of for use specifically as.backfill for the ..sewer lines at this Tract, in and of itself, poses no threat tO groundwater or human health. Th~' " site has been fully characterized and a Remedial Action Plan implemented. BenZene, Tolulene, ' Xylene and Ethylbenzene are not detected at all in this soil. The relative concentration of, ' residual~petroleum, being less than 1000 ppm, is analogous to a abOut a jigger ofoil homogeneously mixed throughout a wheelbarrow full of dirt. Those low concentrations fully meet State Water Resource Control Board guidelines for allowing residual petroleum impacted soils to be left in place without any adverse environmental consequence. In the future,, however, I will personally make it a point to confer with Public Works before considering.any such determinations where City easements might be involved. .

(SEI) followjng the completion of sampling the biorenlediating 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 tbr The Disposition of this soS/dated February 12, 1998 was verbally approved by Hassan Jakhar of the Regional Water Quality Control Board on February 13, I998 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 trenches on the subject site (see Plate 2 for Plot Plan). FIELD WORK CONDUCTED Previous Sampling Events Of Bioremedlating Soil Three (3) series of composite soil sample collection events have occurred at the biocells to evaluate the progress of the bioremediation. The sampl~g events have consisted o1[ collecting 4 soil samples from each 1/4 section of the bio cells and combining them into I sample for analysis. The composite 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 1 and shows a significant decrease in the petroleum hydrocarbon concentrations over time. Current Sampling Event Of Bloremediating Soil The 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, 4700 DISTRICT BLVD.

Sec 6. ~.k..,ers[ield, California Page N..o.. 2, D) were collected randomly in the top 1 to l¼ feet in each section of the biocetls and composited at Zalco Laboratod. es, Inc.. The composite soll samples were analyzed for Total Recoverable Petroleum Hydrocarbons (TRPH) by EPA Method 1664. Every £ffth composite soil sample was analyzed ~or volatile organics (BTEX) by EPA Method 8020 and for T?H as diesel by LUFF Method, Six sets (3 from each bioce~l) of deeper composite samples (greater than 11/2 feet bgs.) were collected and analyzed for TRPH at every thkd sampling location to evaluate the deeper soil for use as backfdl material. In total 112 soil samples were collected from the biocells and composited into 28 samples. Each soil sample was co~ected in a brass tube, sealed with a Teflon lined cap, labeled, and placed ia iced storage prior to being transferred to Zalco Laboratories for chemical analysis under Chain-of Custody 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 1 ~/i feet had analytical results below 1,000 parts per million (ppm). TPHd results ranged lt'rom 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 fi-om below 1¥i 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 backf'fll 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 backftll material it should be further bioremediated to acceptable levels prior to 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 1~/~ feet and should be mixed with clean soil prior to use. The soil below 1¥,- feet is stained and still has petroleum odor and if used should be mixed at a ratio of I to 1 with clean soil. If this soil is not used as backfill material it should continue to be ~ 805-851-2ill SOILS ENGINEERING 8?9 P04 FEB 19 '98 10:15 BLS ENGINEERING, INC.

During the removal of the soil from 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 1 V2 feet in the 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 lithe trenches should be linfited to the top 10 feet Md should be covered by asphalt paved roads. The pavement will limit 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 ha the sewer line trenches as backfill material and compacted. This work will begin following verbal approval of this report by the RWQCB and the FDES.

(SE1) following the completion of a portion of the bioremediation of the soil' excavated from the subject site (see Plate 1 for Location Map). The hydrocarbon impacted soil in the two (2) biocells has been tilled, watered, fertilized and maintained for the past 5 months. Oil and grease concentrations have decreased significantly in at least the top 1 foot of soil and it is proposed to use this soil as backfill material in sewer line trenches on the subject site (see Plate 2 for Plot Plan). REMEDIAL ACTION'COMPLETED Bioremediation Of Hydrocarbon Impacted Soil Approximately 23,600 Yards of petroleum hydrocarbon impacted soil were transported and placed in tw6 biocells constructed directly south of the excavation area. The west biocell (70 feet wide by 1700 feet long) was constructed in the top 5 feet of a former canal. The east biocell (80 feet wide by 1700 feet long) was constructed 15 feet east of the west biocell with an elevation of 3 feet above ground surface. Approximately 24 to 36-inches of the hydrocarbon impacted soil was placed upon the clean sand across the biocell. See Plate 3 for a diagram of the biocells. Three (3) series of composite soil sample collection events have occurred at the biocells to evaluate 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 results of this analytical testing is presented on Table 1 and shows a significant decrease in the petroleum hydrocarbon concentrations over time. The hydrocarbon impacted soil within the biocells are currently being tilled and watered weekly (if needed) to promote the hydrocarbon degrading microbes within the soil. In addition, fertilizer (ammonia nitrate and chicken guano) has been periodically added to the soil to stimulate the bioremediation process. PROPOSED SCOPE OF WORK Adjacent to the biocells a sewer line project is underway for a new housing project on the subject site (see Plate 2). It would be beneficial to use the top 1 foot or greater of soil in the biocells as backfill material for these sewer line trenches. This would eliminate the need to import backfill material from off-site sources.and expose the bottom 1 to 1 1/2 feet of material in the biocells. The bottom section of the biocells can then be effectively be bioremediated in a shorter time frame. The soil we are proposing to use as backfill material will be tested prior to use. Four (4) soil samples will be collected from each 500 cubic yards of soil (every 150 feet along the biocells) in the top I foot or greater of the biocells and composited at a certified analytical laboratory for TRPH analysis by EPA method 418.1. Every fifth composite sample will also be analyzed for volatile organics (BTEX) by EPA Method 8020 and for TPH as diesel by EPA Method 8015. Additional deeper composite samples (greater' than 1 ~/2 feet bgs.) will be collected and analyzed for TRPH at various locations to evaluate the deeper soil for use as backfill material. It is estimated that a minimum of 14 composite soil samples from each biocell will be collected and analyzed (28 total). Areas that have TRPH concentrations less than 1000 parts per million (ppm) will be used as backfill material at depths above 10 feet below ground surface (bgs.)in the sewer line trenches, compacted and covered by asphalt paving. Areas that have TRPH concentrations greater than 1000 ppm will be mixed with clean fill material to reduce the overall concentration to less than 1000 ppm TRPH,(verified by sampling), if this material is needed as backfill. If the biocell material over 1000 ppm is not used as backfill it will be further bioremediated to acceptable levels prior to use. · Potential Impact To Soil & Groundwater The soil placed into the sewer line trenches will be limited to the top 10 feet and will be covered by asphalt paved roads. The pavement will limit 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. The bioremediating soil should continue to degrade overtime in the sewer line trenches to even lower concentrations. Some mixing of this material with existing soil will occur when backfilling and compacting, further reducing the overall concentrations of petroleum hydrocarbons in the soil. SOILS ENGINEERING, INC. Workplan For Soil Deposition File No. 97~8308 For Tract 5426, T30S, R27E, Sec 6, Bakersfield, California Page No. 3 The latest gauging of the depth to water at the existing monitoring wells at the site took place on January 16, 1998. Only well MW-6A had water present at a depth of 44.52' bgs. Since this well is the closest to the biocells and sewer lines (approximately 200 feet north of biocells and 500 to 2000 feet north of sewer lines) the estimated water table below the biocells and sewer lines is greater than 50 feet bgs.. Since there will over 40 feet between the bioremediating soil and the water table, it appears that there is very low potential that this soil would ever impact the groundwater beneath the sewer lines. Schedule Of Work The sampling of the top 1 foot of soil in the biocells will be conducted on February 13, 1998. The results of this sampling should be available by February 17, 1998. A report describing the sampling event with analytical results will be sent to the RWQCB and the City of Bakersfield Fire Department Environmental Services for approval prior to using the material as backfill for the sewer lines.

March 6,1997 Regional Water Quality Control Board 3614 East Ashlan Avenue Fresno, CA 93726 Atm.: Shelton Gray Subject: Site Assessment Workplan Tract 5426 Cladham Common Drive Bakersfield, California Mr. Gray: This Site Assessment Workplan is submitted by Soils Engineering, Inc. (SEI) following preliminary soil borings which have indicated significant oil contamination in soil to a depth of at least 30' and possible water contamination at the subject site. Further assessment of the soil and groundwater is recommended to define the lateral limits of the soil and groundwater impacted by petroleum hydrocarbons from a suspected oil sump. The following scope of work is proposed at the subject site. 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 oil impacted soils were encountered along Cladham Common Drive between Attleboro and Maidenhead Avenues (see Plot Plan, Plate 2). The stained surface area is approximately 120 feet long by 40 feet wide. According to Map 422 of the Division of Oil, Gas and Geothermal Resources, published January 13, 1996, two plugged and abandoned-dry holes were 6tilled within Section 6, although not in the location of Tract 5426 (see attached Map, Appendix B). Castle & Cooke California, Inc. (owner) requested Soils Engineering to do a preliminary evaluation of the contaminated area. SUMMARY OF PRELIMINARY SOIL BORINGS On February 25, 1997, SEI conducted 3 hand auger borings to a depth of 8 feet in the area of surface oil staining (approximately 120 feet by 40 feet). 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 I and 8 feet below ground surface (bgs) at each 4700 DISTRICT BLVD. ° BAKERSFIELD, CALIFORNIA93313 · PHONE (805) 831-5100 · FAX: (805) 831-2111 805-831-2111 SOILS ENGINEERING 632 P03 MAR 10 '9? 14:48 ~ ~l~lL$ ENGINEERING.

Soil sample S-1-1 was also analyzed for lead to evaluate metal concentrations. Oil odor and sta~ng was evident in borings S-1 and S-3 fxom surface to 8 feet bgs. Oil staining and odor began at 3 feet bgs tn S-2 and continued to 8 feet bgs. Analytical results of these sou samples indicate no benzene or toluene and only trace concentrations of ethylbenzene and xylencs. 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 I and the attached analy'dcal reports (Appendix A) for more detail. Since the. base of the hydrocarbon plume 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 plume. Boring B-1 was drilled with a hollow-stem drilling rig on February 28, 1997 between hand auger borings S-1 and S-3. Oil 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. Upon retrieval, the downhole hammer showed evidence of oil on it's surface, indicating possible floating oil (product) on the groundwaters surface at approximately 29 feet below ground surface (bgs). A second boring (B-2) wa~ drilled near handauger S-2 to evaluate the vertical depth of oil staining in this area. Drill cutting indicated moderate oil 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 augers and analyzed for BTEX. A bentonite seal was placed at the bottom of each boring and back,ed up to grade. The soil sample from B-1 at 30 feet had 5,000 ppm oil and grease reported and samples from 15-2 at 20 and 25 feet had 5,200 and 3,700 ppm oil and grease reported, respectively. The groundwater sample collected from B-2 had 73 pans per billion (ppb) benzene and 380 ppb ethylbenzene reported. See Table 1 and Appendix A for more detail. SCOPE OF WORK The following tasks detail the proposed assessment work to further assess the soil and groundwater conditions beneath a suspected oil sump or pipeline leak. TASK 1 Obtain Monitoring Well Permits Monitoring well permits for the 3 proposed wells will be obtained from the Kern County Environmental Health Services Department (KCEHSD). Underground surface alert (USA) and KCEHSD will be notified at least 48 hours prior to drilling activities. TASK 2 Drill 6 Soil Borings to 40 feet, Complete 3 As Monitoring Wells SEI will utilize an SEI owned and operated Hollow-stem auger drill rig to advance a minimum of 6 soil borings in the area of the suspected oil sump.

Three of the soil borings will be drilled to an estimated depth of 27 feet or just above the water table. The other three borings will be drilled 10 feet beIow the fa'st water er~countered (expected to be 30 feet) or to 40 feet bgs. One boring wi[l be drilled w~t~ the known oil stained area, and the other 5 borings around the perimeter of the stained area (see Plot PI~ for proposed locations). Soil samples will be collected at 5 foot inte~als and evaluated in the field for petroleum hydrocarbons (staining aad odor), soil type and photo-ionization detector (PID) readings. A soil sample from each sampling interval will be sea[ed, labeled and placed in an iced cooler. If hydrocarbon contam~ation is encountered in the lateral borings to the proposed depth of the boring, additional drilling and sampling will be recommended to characterize the lateral extent of contamination. Following authorization from the client and regulatory over-sight additional drilling will be conducted. A minimum of three of the borings will be completed as monitoring wells by installing 2-inch schedule 40 PVC casing in each boring. Fifteen feet of 0.020" slotted casing will be instal/ed with approximately 25 feet of blank casing to the surface. A sand filter pack will be placed in the annular space from the bottom of the boring to a minimum of 2-feet above the slotted interval. A minimum of three feet of bentonite will be placed above the sand pack with cement grout to the surface. Each well head will be protected with an eight inch traffic rated well box. A monitoring well construction diagram is presented on Plate 3. TASK 3: Groundwater Sampling Upon completion, each monitoring well will be measured for water depth and the presence of free-floating product, fully developed, purged and sampled. All water samples wil/be collected in 40 mi VOA bottles and l-liter bottles, labeled, chilled and transported under a cha/m of custody to a California state certified laboratory. TASK 4: Well Survey The monitoring wells will be surveyed for relative location and well head elevation. The results of the sttrvey will be combined with the depth of water measurements to determine the current groundwater gradient beneath the site. TASK 5 Analytical Testing Selected soil samples (approximateIy 15) will be analyzed for Oil and Grease and benzene, toluene, ethylbenzene and xylenes (BTEX) by a State certified analytical laboratory. A soil sample will also be collected from the cuttings pile for analysis for Oil and Grease, BTEX, and CAM 17 Metals. All Groundwater samples (3) will be analyzed for oil and grease, and BTEX, one sample will be analyzed for complete geochemical (which includes electrical conductivity, total dissolved solids, barium and many others) and CAM 17 Metals. 805-831w~111 S~ILS EN~INEERIN~ 65~ P05 MAR 10 ~97 14:49 S~IL$ ENGINEERING, iNC.

Page No, 4 TASK 6 Probable Remedial Action Following the assessment of the oil sump area the majority of the oil impacted soil will be excavated with an excavator to the depth of the plume, estimated to be 30 feet bgs. Oil staining and odor will be used to determine the extent of the excavation along with photo-ionization detector (P1D) readings. Once the excavations extent is apparently completed, sidewall (8) and base (4) soil samples will be collected to confirm the removal of the majority of the hydrocarbon impacted soil. The sides of the excavation will be sloped to prevent cave-ins. The soft samples will be collected from the excavator bucket with brass sleeves, sealed with Teflon lined caps, labeled and placed in a cooler with ice. The soil samples (12) will be analyzed for oil and grease, and BTEX. The excavation area will be fenced off to prevent public access to the area. Backfilling and Compacting Excavation The excavation will be bacldilled with "clean borrow" and or imported fill from the base of the excavation to the ground surface. Compaction testing will be done to verify compaction to at least 90%. Alternatives For The Disposition Of Hydrocarbon Impacted Soil Depending on the amount of hydrocarbon impacted soil removed from the excavation, the soil will either be transported to a permitted recycling facility, bioremediated on-site or used along the top 1 foot of road surfaces of the development and covered by asphalt. Recycling At Disposal Facility After acceptance at a permitted recycling facility the soil will be transported under non-hazardous manifests to the accepting facility for recycling. This is the most expensive remedial option ($30 to $35/ton). On-site Bio. Retnediation A sample of the stockpiled hydrocarbon impacted soil will be collected and analyzed for biotreatability. If the biotreatability study shows that bioremediation will be successful, a biocell will be built in a remote area of the development. The biocell will be created by forming a 3 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 biocell upon the visqueen to serve as a buffer zone between the visqueen and the hydrocarbon impacted soil. Approximately 18-inches of the hydrocarbon soil will be placed upon the dean sand across the biocell. 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 805-831-2111 SOILS ENGINEERING 632 P06 MAR 10 '9? 14:49 S~ILS ENGINEERING, INC, Site Assessment Workplan, Cladham Common Drive File No. 97.8144 For Tract 5426 T305, 1~27E, Sec 6, Bakersfiel~ Californ~ ........ ~ Page No. $ 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 less than 1,000 parts per million oil and grease the soil will be considered bioremediated and placed along road surfaces of the development and covered with asphalt. Place Soil Along Road Surfaces The hydrocarbon impacted soil will be placed along the top 1 foot of the road surfaces within the development mad covered by asphalt, The asphalt will prevent infiltration of water into the hydrocarbon impacted soil to prevent any migration of the hydrocarbons and help bind the hydrocarbons in-place. This is the most cost effective and expedient remedial alternative for the soil. TASK 7 Assessment/Remedial Action Report An Assessment/Remedial Action Report will be prepared for the client detailing field procedures conducted, analytical resuIts of soil and groundwater samples analyzed, boring logs, cross- sections and conclusions and recommendations for the site.

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. Crude oil constituents are the identified hazardous substances at the site. The more volatile components, especially benzene, pose the greatest 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. See Appendix C for Site-Specific Health and Safety Plan for more information. 805-831-2111 SOILS ENGINEERING 632 PO? MAR 10 '9? 14:50 SOILS ENGINEERING, INC.
