The attached "~ .................. memorandums_discusses the_adequacy, of .the information.you_provided ~LL .... pursuant to our original request, 26 August 1988. As indicated in. the attached memorandum, we have concluded that the proposal does not adequately address our concerns with respect to lateral and vertical definition of the plume boundaries. I '. ,. " You have indicated to us that you would like to implement a ground water extraction program at the site as soon as possible. We concur that it would be beneficial to initiate this process in a timely fashion. We will therefore begin developing waste discharge requirements for the discharge so that the extraction and treatment can begin as soon as possible. The purpose for developing waste discharge requirements for this operation is to ensure the protection of the ground water quality at the discharge location following ground water extraction and removal of petroleum constituents. The development or adoption of the waste discharge requirements does not imply that the extraction system has been or will be adequately contstructed to control the plume. To the contrary, no information has been provided that demonstrates that the system will be located, constructed or operated in a manner to control the entire plume of contamination. Prior to 4 November 1988 please provide us with a work plan which outlines how you propose to define .the lateral and vertical' boundaries of the plume and how the other items in the attached memorandum will be addressed. - If you should have any specific questions regarding the information we have requested, please telephone Ken Wilkins of our staff ~t (209) 445-6191.

NEVINS SENIOR ENGINEER FROM: KEN WILKINS STAFF ENGINEER DATE: S U BJ ECT: OCTOBER 03 1988 DAVIES OIL COMPANY, BAKERSFIELD INTRODUCTION Oh '11 jUly 'ig~8"~'-"~ceived an appIication-for""W~-~iEc-h~'~e from Delta Environmental Consultants on behalf of Davies Oil Company. Delta was hired to investigate the extent .of contamination which resulted from a leak of approximately .2500 gallons of regular grade gasoline at the subject facility. Delta proposes to remove dissolved ~etroleum hydrocarbons and then discharge the treated water to an infiltration pond on site. The facility is located in a commercial/industrial area northwest of the City of Bakersfield in Section 23, T29S, R27E, MDB&M. Upon review of the information submitted by Delta it was apparent that petroleum based contamination is present in the soil and ground water at various locations throughout the site. We therefore indicated that the following additional information needed to be provided for our review as part of a next phase investigation at the site: 1. Definitibn .of the outer boundaries (both lateral and vertical) of the contamination at the site including the plume from the known leak of regular gasoline and all other contaminated areas. 2. Definition of the extent of soil contamination (both lateral and vertical) throughout the entire site. Probable cleanup strategies.should be outlined for our review. 3. Information regarding the removal capabilities of the proposed treatment system, and construction details of the proposed infiltration gallery. We requested a technical report with a work plan addressing the above issues be submitted for our review. CURRENT SUBMITTAL On 09 SePtember 1988 Delta submitted information pursuant to our _request. The following is a brief..summary of _..the .information submitted, by Delta with reSPeCt~'~O the three above items. [Reviewed by' [ ~AJ Item Delta indicates in the 09 September .letter that a work plan to define the vertical-.and lateral extent of the dissolved hydrocarbon plume (from the confirmed leak) was included in a quarterly monitoring report~ dated 10 January 1988. The proposal called for "three and possibly four additional monitoring wells be installed at the site." The letter also references .the 10 ~an~arY~-~quarterly contamination at the site (not attributable to the confirmed leak of regular grade gasoline) and states; "the necessity of addressing the apparently separate contamination in MW-2 and MW-3 can. be re-evaluated at a later date, based on data collected during future investigation and quarterly monitoring at the site." ............................. 6~l{~%~d-i6ates. that ,,future~inves~igations,,'~'ill~-b~-'~0hd~tedto evaluate the impacts of the "apparently separate contamination". A request was made to outline what work would be completed pursuant to investigating the contamination in our original letter, but no new work has been proposed by Delta in the 09 September letter. Of the four "new" wells proposed, three of the wells (MW-10, MW- 11, MW-12) had already been installed at the time of my original review. The three wells were installed on the Davies property and clearly indicate the presence of petroleum constituents in the ground water. The fourth well, MW-13, was proposed to be completed downgradient off-site but was never constructed. Since that time no work has been accomplished and no additional wells have been proposed (except MW-13) to define the downgradient lateral extent of contamination. Also, no ~ork has been .accomplished or proposed to determine the extent of contaminant migration in the vertidal direction. Delta contends that they cannot determine the south/southwest boundary of the plume of petroleum contamination because they have been denied access to the property south/southwest of the leak location. Delta has provided correspondence which indicates that they have offered the occupant of the immediately adjacent property (Mr. Cyril Andre) a single payment of $500 for right of entry to the property to construct a monitoring and/or extraction well(s) and operate the wells for an indefinite period of time. It is questionable whether this is'adequate demonstration that the lateral boundary of the plume cannot be determined for .the following reasons: 1. There is no evidence that the offer of a single paYment of $500 is an adequate offer for right of entry to the property for an indefinite period of 'time or that it will even reimburse Mr. Andre for his costs and inconvenience for the proposed time period. 2. There has been no proposal provided for alternative well locations if Delta is not granted right of entry to the property. In addition to the lack of adequate work to identify the plume in the lateral direction, there has been no work conducted to' determine the vertical eXtent of contamination. The current plans are to construct an extraction well without sufficient knowledge of whether or not the plume will be captured and contained. Item In the 09 September letter Delta did not propose any additional work to define the extent of soil contamination at the site. Similarly, no cleanup strategi.es were proposed. Information regarding the removal capabilities of the proposed treatment system and construction details of the proposed infiltration gallery were not included in the 09 September letter from Delta. Mr. Talanki, 'a Delta representative, indicated that the proposed treatment system had been re-designed to incorporate new features and that the new design would be submitted for our review sometime in the near future. Similarly, the construction details for the infiltration gallery are to be submitted shortly. CONCLUSIONS In our original letter we requested that a work plan be submitted to address the lateral and vertical extent of contamination on and off-site, including both the plume from the confirmed leak of gasoline and all other contaminated areas. The response that Delta has provided does not propose any work which has not previously been completed ahd reviewed with the exception of the proposed installation of MW-13. The work that has been completed at the site indicates that ground water has been impacted. It does not define the boundaries of contamination. No work has been proposed to define the plume boundaries laterally or vertically yet Delta has proposed to implement a .ground water extraction program under these unknown conditions. .

'. Dear Mr. Wilkins: Enclosed is the information requested in your letter dated August 26, 1988, and also additional information pursuant to your /telephone conversation with Mr. Michael Westerheim of Delta on August 31'71988. A work plan to define the horizontal extent of the dissolved .¥hy'droc;arbon plume was included in the quarterly monitoring report dated January 10, 1988 (attached). Additional monitoring wells were proposed at, that time. Monitoring Wells MW- 10 and MW- 11 were installed, and MW- 12 and MW~ 13,were not because we were denied access to the property. We still recommend that MW-12 and MW-13 be installed to define the~downgradient ex.-t~iit''0f the plume. As soon as ROE is obtained we will proceed' with 'the proposed work plan. Copies of the correspondence between Delta and adjacent property owners to gain "Right of Entry" are included with. this letter. The $1,000.00 permit application process fee is being sent separatelY. A brief description of our attempts to gain ROE (Right of Entry) is as follows: Figure I shows the site vicinity map. Mr. Cyril Andre is the owner of the property adjacent to the site. He has refused to grant us the ROE to install a monitoring well on his property. Mr. Francis Perey is the owner of the property which has been leased to Mr. Jim Boylan of Jim's Steel and Supply. We proposed to drill monitoring wells MW-12 and MW-13 in our report dated January 10, 1988. Mr. Francis Perey granted us the ROE on January 20, 1988 contingent upon approval from Mr. Jim Boylan. '-Mr. Jim Boyish has refused us permission to drill on the site. Delta has made efforts to resolve the problem in good faith but until we get cooperation from the owners of the adjacent properties we cannot proceed with our proposed work plan. As we have discussed .in our quarterly monitoring reports dated January 10, 1988 and June 10, 1988 we would like to recover the free product and install a ground water treatment system at the 'site based on the known free product plume size. We would like to start the remediation process as soon as possible to contain the known contaminant plume.

T~e 'flow gradient is relatively flat (about 0.003 ft./ft.) and conforms to local topo- graphy. Transport of contaminants should, therefore, be from the leaded-gasoline leak location (see Figure 3) toward the west and southwest. The presence of free product (gasoline) in IvIW= I would tend to confirm this assumed pattern of contaminant transport. The high level of total purgeable hydrocarbons (as gasoline) in MW-9 may also fit with this flow pattern.. However, MW-9 is located over 400 feet down-gradient of the leak location. Since the gradient is relatively flat, several years would be required for contamination from the leak location to have reached lVlW-9. The exact time required depends on the porosity and hydraulic conductivity of the underlying sediments, but under the most favorable conditions, the plume from the identified leak would not be expected to reach MW-9 in less than five years. There is the possibility that as yet unidentified sources have contributed to the contamination of soil and ground water at MW-9. Unless the local ground-water flow gradient is subject to wide seasonal directional variations, the presence of Iow levels of dissolved hydrocarbons in monitoring welh MW-2 and MW-3 seemingly cannot be explained by transport of contaminants from the known leak locations. Flow gradients determined in December, 1987, indicate that these wells are' not down-gradient of the known leak location ~~i[.[l~~'~! ~'~ (especially lvlW-3).~J~"Furthermore, both weLLs contain at least traces of diesel #2 (in l/ dissolved phase); product lost at the known leak location was regular-grade gasoline.

The necessity of_addressing the apparently con,ruination in MW-2 and MW-3 can be re-evaluated at a later date, based on da~a collected during future investigation and quarterly monitoring at the site. The I~ern County Health Department has expressed concern that the vertical extent of contamination ...... beneath_the.. _n.0w-remoyed.d.i. eseJ_~.n!~___.~_.~0_t~.~en defined. Since soil borings B-5, B-6, and B-? (adjacent to the former diesel tank locations--Figure 3) were substantially free of contamination and since ground-water samples 'collected from monitoring-well lVlW-8 (directly down-gradient of the former diesel tank location) have shown no trace of contamination, we believe that any significant soil contamination at this location was removed during the tank excavation process. If any con- tamination is present, it may be effectively controlled and removed by remedial efforts in the area of the known leak location. ,~.0 PROPOSED ADDITIONAL wORK Based on the preceding discussion, we recommend that at least three and possibly four additional monitoring wells be installed at the site.

The wells wiU be advanced by hollow-stem auger drilling, using methods outlined in Section 5.0. Borehole diameter wiU be approximately seven inches. All monitor- ins wells will be advanced a minimum of ten feet below the water table; screened intervals will extend approximately five feet above and ten feet below the water table. Actual screened intervals and well depths will be determined in the field by a Delta geologist or engineer. The annulus around the screened interval will be filled with clean, imported gravel. The gravel pack will extend one or two feet above the top of the screened interval. Above the gravel pack, a bentonite seal at least two feet thick will be installed. The annular space above, the bentonite seal will be grot~ted to the surface.

We recommend that the well be completed with 12-inch casing to allow clearance for a down-hole, dual-pump system. The borehole would be 20 inches in diameter, leaving a 4-inch annular space to insure adequate gravel-pack thickness. We recommend use of a ~0 slot (0.040"), continuous galvanized screen. The screen should be 20' feet in length and should be set between I? and 37 feet below grade. Gravel-pack material should consist of uniformly graded, coarse sand (Monterey #3 or equiva- lent), and should extend 3 or 4 feet above the screened interval. See Figure 6 for typical recovery-well construction specifications. 4.2.3 Aouifer Test Soecifications .......

This information will be used to design a water treatment system. Treatment and disposal of water produced by recovery wells is a primary design consideration.' After. an initial investigation, it is .apparent that three water-disposal..opfions exist._These ....... options are: 1~ .discharge to existing storm sewer, 2) infiltration or injection on site, and discharge to existing sanitary sewer. Option 1, discharge to an existing storm sewer, would require that a National Pollutant Dis- charge Elimination System (N'PDES) permit be secured from the U,~. EPA. Water discharged to a storm sewer would likely need treatment, using the best available technology, to high standards (possibly drinking-water standards) under the terms of an NPDES permit. Extensive monitoring of the quality of the discharge water would also be required. During a December field visit, it was observed that no nearby storm sewers are available. Storm water in the area is apparently controlled by surface run-off. __O.n_-.s.ite._i.n_f_il_trati.0n__(_O_p.tion 2)...may also be an acceptable option: Water to be re-injected or allowed to infiltrate may also require treatment to near-drinking water standards. Compliance II with such standards may require installation of expensive and maintenance-intensive treatment' equipment on site. In addition, chemical constituents ~at may occur naturally in the water (iron, carbonate) and bacterial components may have to be removed to prevent plugging of the infiltration gallery. Option 3, discharge to an existin, g sanitary sewer, seems to be a practical solution. A City of Bakersfield sewer line is located approximntely 750 feet southeast of the site. However, the Bakersfield Department of Public Works (DPW) has indicated a reluctance to allow discharge of produced water to the sewer. The city requires that any discharge to the sewer must be cert- ified by the California State Department of Health Services (DHS) as 'non-hn~rdous" under the requirements of the California Administrative Code, Title' 22, Division 4, Chapter 30, Article An off/cial in the DHS, Alternative Technologies Division, indicated that such certifica- Davie~ Oil Company C~u~erly Monitoring l~e~ults ~, Propo~d Work Delta Proiec~ No. 40-87-~26 P~ge 21 _~ :_.=_ :t ion normally_takes at least one year to complete. Only after the discharge is certified as non-h~%dous will the Bakersfield DPW consider allowing the discharge into the sanitary sewer. However, officials at the DPW will not guarantee that the discharge water will be allowed to enter .the sanitary sewer, even if it is classified as a non-hazardous waste. ......... -~' re~resentatives Will Con~n~ 'to Work 'Wi~ ~the'city Of 'Bakersfield,' th~ California Depart-,- ment of Health, and the San :Ioacluln District of the Regional Water Quality Control Board to insure that the water discharge will be disposed of in a mutually-acceptable nmnnner.' .. f,O METHODS All field work, data analysis and interpretation will be conducted under the supervision of a California Registered Geologist. $,1 Soil Samuline and Contamination Reduction Monitoring-well drilling and soil sampling will be. performed under the direction of a Delta engineer or geologist. The monitoring wells will be advanced using a truck-mounted hollow-stem auger drill rig. Upon recovery, a portion of the soil s~mple will be placed into a glass jar and sealed for later screening with a photoionization deteclor. Another portion of the soil sample will be used for classification and description. That part of the soil sample collected in brass tubes wit_hin the California-type sampler will be stored at approximately 4o C. for transport to the laboratory. We propose to utilize Central Coast Analytical Services, a State of California certified laboratory, to perform the chemical analyses. QUARTERLY MONITORING' I~PORT Daviu Oil Compaay,.Ba~erafield CA Delta Project No. 40-87-326 P~e 9 On May 2, 1988 free-product thicknesses and water levels were remeasured. In May, MW-I contained 0.8 feet of free product. Water levels in the other monitoring wells were more than 1.5 feet lower than in March. 'A water-table contour map was constructed from water level data obtained on May 2, 1988 (Figure 5). The inf~erred direction of ground-water flow is from northeast to southwest. The gradient of flow calculated from Figure 5 is 0.003 feet/foot.. : 2.~ Ground-Water (~hemicai Analyses t Each m~nitoring well, except MW-I, was bailed and sampled on March 4th or 5th, i988. MW-I was not sampled because of the presence of free product in this well. The samples were submitted for analyses of BTX, ethylbenzene, EDB, EDC, and TPH by EPA method 524.2. The results are summarized in · Table 2 and the laboratory reports are included in Appendix C. Table 2 also contains the chemical results from May and October 1987 for comparison. 1 ,] Maximum benzene concentrations in ground water were present in monitoring well MW-11 at 10 parts per million (ppm). Water from the other monitoring wells contains benzene at concentrations less than 1 ppm, if it is present at all. The .highest TPH values are also found in monitoring well MW-I 1, at 240 ppm. Monitoring welli MW-12 and MW-9 also contain elevated concentrations of TPH, at I00 ppm (70 ppm in the duplicate) and 70 ppm, respectively. ~.0 DISCUSSION OF RESULT~ Additional soil borings at the Davies Oil Company property confirm that the site is underlain by sandy silt and sand with pebble and gravel horizons. A sieve analysis performed on samples collected from 20.5 and 29 feet below grade indicate that the soil is within the sand grain-size classification. ? An approximate hydraulic conductivity (K) can be calculated from grain=size distribution curves.using an empirical relationship known as the Hazen approximation (Freeze and Cherry, 1979). This method yields an approximate value for K on the order of 102 ft/day. Although attempts at securing permission for an off-site downgradient well have so far been fruit- iess,'theSe efforts will continue. 'Such a well is necess~ t_Xo_~tmen~the ,"-~* o~-4~n~i~iiU8n--::~-'--~- and the effectiveness of the recovery well. While we consider it important that a downgradient well ~e i~mned, we dO not fielieve that remediation efforts should be delayed until the downgradient ' extent of the plume' is defined. .. .~- .....' ................ Preliminary ~alculations indicate that' the~-re¢overy well installed on ~May ~rd, 1988-,should recover · free petroleum product and ground water containing dissolved hydromrbons from most of the southern ! portion of the site. After this well has been tested, and more extensive analyses performed, recom- ' mendations may be made regarding the locations of additional recovery wells, if they are necessary. Ground water levels rose more than one foot from December 1987 to March 1988. Water levels then dropped more than 1.5 feet between March and May 1988. These water table movements may be due to normal seasonal fluctuations. The inferred direction and gradient of ground water flow in May 1988 is consistent with measurements made in October and December 1987. A survey of water wells in the area indicates that there is no knower use of ground water in the immediate area. One abandoned well was located on the Teamster's Union property, west of the site. Review of well-monitoring results indicates the presence of free product on the water table in the area near MW-I. Five feet of product accumulated in recovery well RW-1 after only three hour~ of pumping. RWol should be effective in removing the floating product. Installation of additional monitoring wells MW-Il and MW-12 seems to indicate that a plume of dissolved petroleum constituents extends from the area of MW-I to MW-9 off site to the west (Figure 6). MW-10, installed up gradient of the known leak location, contains very low levels of dissolved constituents. Delta continues its efforts to work toward a suitable water discharge optiOn with appropriate City of Bakersfield and Kern County agencies. Recovery and treatment of contaminated ground water will begin as soon as possible to prevent the further spread of dissolved hydrocarbon constituents. QUARTERLY MOHITOR.12~G REPORT Davie~ Oil Company, Bs&ersfield CA Delt~ Project No. Page 14 4.0 FUTURE WORK During the next quarter Delta will be evaluating two different options for disPoSal of the' 'ir0-un~i water generated during cleanup at the site: Option 1, discharge to the City of Bakersfield Sanitary Sewer 'and Option 2, discharge to an infiltration gallery located on the northeastern portion of the site. The evaluation will be based on initial capital cost and long-term maintenance, monitoring, .... and treatment costs Once a disposal alternative has been selected, a water-treatment system wUl be desi8ned to meet the discharge'water quality criteria required by that alternative. Required permits will be applied for . depending on the treatment technology chosen. We anticipate that a product-recovery and water-treatment system sufficient to control the free product can be designed and installed at the site in approximately three months. Based on the known plume size, one well will not be sufficient to control the plume of con~minated ground water, and additional recovery welh will have to be installed. Modifications to the treat~ ment system will likely have to be made to accomodate the increased volume of recovered ground water. Once RW-1 has been operated for approximately one month, and data has been collected establishing its capture zone, additional recovery wells can be specified as needed, depending on the extent of the uncaptured contamination plume. We anticipate a total discharge of between 100 and 150 gallons per minute once the gradient control system is in full operation.' The next monitoring-well sampling event should take place just prior to-recovery system start'up, which should be sometime in August 1958.

(Delta) on behalf of Davies Oil Company, Bakersfield is submitting a preliminary Authority to Construct/Air Permit Application for a packed column air stripper to remove petroleum hydrocarbons from gro/~nd water at the referenced site. The purpose of this preliminary application is to determine if the proposed air emissions are feasible and if further evaluation is necessary. The application will be signed and dated once we agree upon your recommendations. After reviewing the enclosed information please contact Delta with your comments. Site and Recovery Well Description The site location is described in the attached quarterly monitoring report dated June 10, 1988. A site map showing the location of the recovery wells and the location of the proposed treatment system is shown in Figure 1. The discharge rate from the recovery well RW-I is expected to be about 40 to 50 gallons per minute (gpm). A pump test was conducted in May 1988. The ground water from the pump test is stored in a temporary tank kept on the site. Water samples were collected and sent to the laboratory to determine concentrations of dissolved hydrocarbons. The l~iboratory reports are attached. Practical Solutions to Environmental Concerns Mr. Paxson Delta Project No. 40-87-326 August 1, 1988 Page 2 SCREENING LEVEL HEALTH RISK ASSESSMENT The health risk assessment is based on CAPCOA guidelines and is focused on the cancer risk due to benzene emissions from the air stripper. Treatment System Description A schematic of the proposed treatment is shown in Figure 2. Preliminary design calculations indicate a 3 foot diameter packed column air stripping tower. The tower will have a height of 26 feet and will incorporate 17 1/2 feet of packing. The capacity of the blower will be 4,800 elm. The loading on the air stripper is estimated at 7 gpm/ft2 with TPH (total petroleum hydrocarbons) concentrations of approximately 42 rog/1. Emissions Calculations The proposed treatment system is planned to operate continuously. The projected life of the project is 3 to 5 years. Table I shows the expected quantities of air emissions on a daily basis. TABLE 1 Emission Points Flow rate Benzene. TPH Toluene X¥1ene · (~pm) (Ibm/day) (Ibm/day) (Ibm/day) (Ibm/day) Air Stripper 50 0.96 25.2 9.0 9.6 Calculations: The amount of benzene (Ibm/day) released to the atmosphere can be calculated as follows: Mr. Paxson Delta Project No. 40-87-326 August 1, 1988 Page 3 Assumptions: 1) 1.6 mg/1 (average of 2 water analyses) benzene in pumped water. ................. 2) ............ !_00% efficiency of the t_rea~ment system. 3) Pumping rate of ?2,000 gallons/day (50 gpm for 24 hours) 72,000 gallons x 3.79 liters x 1.6 mg benzene x day gallon, liter 2.2 x 10'6lbs mg 0.96 Ibm. benzene day Similarly, the amounts of TPH (42 mg/1 total petroleum hydrocarbons), toluene (15 mg/l), xylene (16mg/l) present in the ground water and emitted to the atmosphere are calculated as: TPH = 25.2 Ibm/day Toluene = 9 Ibm/day Xylene = 9.6 Ibm/day Receptor Description, The nearest building to the treatment facility is a residential building with ap- proximate dimensions of height = 18 feet, length = 55 feet and width = 20 feel There is a trailer court adjacent to the property. Please refer to the site vicinity ma~ (Figure 3) for more information. SUMMARY OF HEALTH RISK ASSESSMENT Table-2 is a summary of the cOntinuous air emissions from the air stripper. Table- 3 is a summary of predicted ambient air concentrations as calculated using the air dispersion model PTPLU (version 2.0). Printouts of the model for benzene, toluene, xylene (BTX), and total petroleum hydrocarbons (TPH) emissions are attached. Table 4 shows the values of excess life time caner risk and the population excess cancer burden for benzene and gasoline vapor~-emissions. - Mr. Paxso~ Delta Project No.'40-87-326 August 1, 1988 Page 4 A After reviewing the enclosed application and information please contact me at (916)638-2085 with your comments on our Preliminary Authority to Construct/Air Permit application and other relevant imfo/-mation.

(Delta) on behalf of Davies Oil Company is submitting a preliminary application for liquid waste disposal to land via an infiltration gallery at the referenced site. The waste will consist of contaminated ground water treated to remove diss61ved petroleum hydrocarbons. The purpose of this preliminary', application is to determine discharge monitoring requirements so that we can evaluate the economic feasibility of this disposal alternative compared to using the sanitary sewer. After reviewing the enclosed information please contact Delta with your comments and proposed monitoring schedule. Site Description A USGS topo map of the site with township, range and section is included in Figure 1. Figure 2 is a site map showing the recovery well (RW-I), and proposed locations of two additional recovery wells, the treatment system and the infiltration gallery. Volume of Waste Discharge The proposed volume of the waste discharge is calculated at 0.216 million gallons per day (MGD) on a continuous basis for a period of 3 to 5 years. Quality of Water to be Treated. ...Laboratory analysis of the source (contaminated .ground ..water) water .are attached. Mr. Kenneth Wilkins July 6, 1988 Page 2 A schematic of the proposed treatment method is shown in Figure 3. The dissolved petroleum hydrocarbons in the ground water are removed by using two packed column air strippers. Preliminary design calculations indicate two 3 1/2 foot diameter packed column air stripping towers. The towers will each have a height of 16 feet and will incorporate 12 feet of packing. The capacity of the blower will be 2000 cfm. .: After reviewing ~ihe "~nclosed 'in~mati0n 'piea~-e -c'0nt~'r'~i~t~"-~tlth'--'"~ ..... comments including discharge water quality and monitoring requirements. · :' If you have any questions regarding this matter please contact me at (916)638-2085.

(Delta) on behalf of Davies Oil Company, Bakersfield is submitting a preliminary Authority to Construct/Air Permit Application for a packed column air stripper to remove petroleum hydrocarbons from ground water at the referenced site. The purpose of this preliminary application is to determine if the proposed air emissions are feasible and if further evaluation is necessary. After reviewing the enclosed information please contact Delta with your comments. ~ite and Recovery Well Descrit~tion The site location is described in the attached quarterly monitoring report dated June 10, 1988. A site map showing the location of the recovery wells and the location of the proposed treatment system is shown in Figure 1. The discharge rate from the recovery well RW-1 is expected to be about 40 to' 50 gallons per minute (gpm). A pump test was conducted in May 1988. The ground water from the pump test is stored in a temporary tank kept on the site. Water samples were collected and sent to the laboratory to determine concentrations of dissolved hydrocarbons. The laboratory reports are attached. Two additional gradient control/contaminated ground water recovery wells will be installed and operated in the future once free product recovery is complete. Their approximate locations are shown in Figure 1. Each of the wells will yield approximately 50 gpm. The total discharge from all 3 wells will eventually be approximately 150 gpm. Practical Solutions (o Environmental Concerns Mr. Paxson Delta Project No. 40-87-326 July 1, 1988 Page 2 Trealment System Descriotion A schematic of Se proposed treatment is shown in Figure 2~ Preliminary design ~ :" calculations indicate two 3 1/2 foot diameter packed column air stripping towers. The ?'-'~ ' towers will each have a height of 16 feet and will incorporate 12 feet of packing. The ~, ~i capacit3r of the blower will be 2,000 cfm. The initial loading (50 gpm yield) on.the · - ....................................... air stripper is estimated at 5.2 gpm/ft2 With TPH (total petroleum hydrocarbons) concentrations of approximately 42 mg/1. The final loading (150 gpm yield) is estimated at 15.6 gpm/ftl with~ TPH concentrations of approximately 10 mg/l or less. EmissiQn$ C~lcul~tion~ The proposed treatment system is planned to operate continuously. The projected life of the project is 3 to 5 years.

Davies Oil Company 3305 1/2 Gulf Street Bakersfield, CA 93308 Claim No. 83Z-40 Delta Project No. 40-87-326 Dear Ms. Cheung: As per your letter dated June 15, 1988, regarding the wastewater discharge permit for Davies Oil Company, we are submitting information to complete the application so that the final discharge permit can be prepared. Item Description A.7 B.3 B.10 C.8 SIC Code - Not a manufacturing facility. 11 Employees, 8 hours/day (estimate). Additional wells - Of the 2 additiOnal wells to be added, the first well will be installed during the installation of the recovery system and tt/e second well will be installed after we get permission to drill off- site and define the extent of the dissolved hydrocarbon plume. Chemical compound Concentration susoected Lead <I ppm Mercury <0:0002 ppm Ms. Cheung Wastewater Division, City of Bakersfield July 1, 1988 Page Two Discharge Limitations .: ...... After reviewing the wastewater discharge concentrations and monitoring " requirements in the proposed permit, we feel that the proposed d~ily maxi. mum :~zl ....................................... discharge limitations are unnecessarily stringent for discharge to an activatedsludge-~. treatment facility. Low levels of dissolved hydrocarbons are easily removed in the .,, activated sludge process by biodegradation and aeration. We propose the following · . .... discharge limits: Parameter Total petroleum hydrocarbons Benzene Concentration in parts per million 10 1 Toluene 5 Xylene 5 Ethylene Dibromide 1 1,2-Dichloroethane 1 Since we are discharging ground water contaminated with dissolved hydrocarbons and our initial chemical, analysis did not reveal significant concentrations of heavy metals, we feel that monitoring the discharge for heavy metals is unnecessary. In addition we have no reason to expect .that the discharge will contain carbon tetrachloride, since this facility 0nly dandles petroleurh products for the transportation industry. Monitorin~ Freauenc¥ Since all the variables affecting process performance are fixed, that is,'the influent to the pretreatment system is ground water at a constant flow rate, temperature, and relatively constant dissolved hydrocarbon concentrations, the performance of the pretreatment unit will be relatively constant. We propose to sample the discharge weekly during the first month after the pretreatment system start up. If the discharge concentrations meet the discharge limitations, monitoring will be conducted on a monthly basis. Ms. Cheung Wastewater Division, City of Bakersfield July I, 1988 Page Three , Special Conditions Please supply us with the estimated costs to be incurred by the city under Part 4 of the special conditions. On behalf of Davies Oil Company, we are making every effort to restore the aquifer in the vicinity of Davies Oil. Ground water in the area is in a highly conductive shallow sand_aquifer with fairly rapid ground water flow rates.. It is-importantthat _,_~;~ - . gradient control be implemented as soon as possible to prevent further spread of the. dissolved hydrocarbon plume, Delta is currently seeking the most favorable economic alternatives to remediate the site.

Water from the other monitoring wells contains benzene at concentrations less than 1 ppm, if it is present at all. The highest TPH values are also found in monitoring well MW-I 1, at 240 ppm. Monitoring wells MW- 12 and MW-9 also contain elevated concentrations of TPH, at 100 ppm · (70 ppm irn the duplicate) and 70 ppm,' respectively. . 3.0 DIsCussION OF RESULTS Additional soil borings at the Davies Oil Company property confirm that the site is underlain by sandy silt and sand with pebble and gravel horizons. A sieve analysis performed on samples collected from 20.5 and 29 feet below grade indicate that the soil is within the sand grain-size clas Sift cation.' An approximate hydraulic conductivity (K) can be calculated from grain-size distribution curves using an empirical relationship known as the Hazen approximation (Freeze and Cherry, 1979).

The purpose of Delta's work is to clean up the contaminated ground water at the site. At present there is no sewer service provided in the area, and our only other option of discharging the treated water is to land via infiltration. The estimated period of discharge is 3-5 years. Based on the information in the permit application please supply us with the following: 1) Maximum discharge concentrations to the sewer. 2) Required monitoring frequency. A signed application will be submitted once. the discharge limits are agreed upon. If you have any questions regarding this matter, please contact me at (916)638=2085. Thank you for your help.

Cheung Disposal of Ground Water Pumped During Remediation Efforts Davies Oil Company, Bakersfield, CA Federated Claim Nos., 83Z-9, 83Z-26 and 83Z-40 Delta Project No. 40-87-326 Dear Ms. Cheung: As we discussed during our meeting on March 3, Delta is planning to in'stall a well for recovery of contaminated ground water at the referenced site. Install- ation o£ the well and subsequent pump tests are scheduled for the week of March 21-26. Delta proposes to discharge well-development water through a temporary hose to a sanitary sewer manhole located in the right-of-way of Arrow Street, east of the property. As indicated in our letter 0f January 14, 1988, to Mr. Joe Turner, we expect to produce 20 to 40 gallons per minute (gpm) from the well, and the time required to complete the pump test will be 24 to 72 hours. The proposed well will be approximately 32 feet deep, and the pump will be placed near the bottom of the well. The liquid level in the well will be closely monitored to ensure that there will be no discharge of free product to the sewer system. Pumping at the indicated rates will require disposal of from about_30,000 to about 60,000 gallons per day. Concentrations of dissolved hydrocarbons are expected to be much lower during pumping operations than identified during sampling at the monitoring wells because of dilution. Concentrations of total dissolved hydrocarbons Will likely be less than 10 ppm. During the test we will sample the discharge daily to document concentrations of dissolved hydrocarbons and gain necessary information to evaluate the discharge and design any required pre- treatment systems.

Prior to discharge of any appreciable quantities of contaminated ground water, proper permitting will be accomplished. In the meantime, we wish to continue with our investigative efforts; installing monitoring wells in the indicated locations to define the extent of ground-water contamination. · A well survey will be conducted when we are on site to drill the proposed monitorin~ wells. We will contact local agencies and residents to determine if potential Conduits for vertical contaminant movement exist within a quarter-mile radius of the site. Enclosed is an application for permit to drill four monitoring wells and one recovery well at the referenced site. We hope to install the monitoring wells on February 25th and 26th, 1988. The recovery well will be installed soon after -- its installation has not yet been scheduled. We have been informed that Kern County policy requires the use of non-PVC well casing for monitoring wells to be installed in areas of known contamination. We are unaware of evidence that suggests rigid PVC well casing is unsuitable for monitoring ground-water contaminated with low levels of petroleum hydrocar- bons. Neither the U.S.E.P.A., the California Department of Health Services, nor the California Regional Water Quality Control Board currently require that non- PVC casing be used in such situations. ............................................... The attached" article;'-excerpte~t-ftom-the -'Fall;-t98-7'-issue-of-"Grof~d' 'ltraikr ........ 'Monitoring Review, seems to suggest that PVC may even b~ superior to stainless steel and other "inert" materials for ground-water monitoring. These data are for RCRA sites, which typically involve monitoring for trace mounts of chemicals much more reactive than those found in petroleum products. Practical Solutions to Environmental Concerns Ms. Amy Green Hazardous Materials Management Program Kern County Health Department February 12, 1988 Page Two -A recentprice comparison suggests-that-stainless'-steel~asing~and screen-is--ten- times more expensive than PVC material. We are unaware of evidence that suggests the additional expenditure is warranted. Therefore, we propose to install PVC well screens and riser pipe.in all wells installed at the site.

Dear Ms. Green: Street The purpose of this letter is to respond to the topics discussed in a phone ,..' conversation between Michael Westerheim of Delta Environmental Consultants ~ and Amy Green and Richard Casagrande of the Kern. County Health Department on ', , 'Friday February 27, 1988. .- The topics discussed included handling of monitoring well development water, the use of PVC for monitoring wells, and right-of-entry access to Mr. Cyril Andre's property. As we discussed, Delta will incorporate the following procedures when performing work at the referenced site. Use of PVC For Monitoring Wells Kern County has indicated that they have information that PVC well casing may degrade when exposed to organic contaminants after approximately two years or more. Therefore Kern County will require the installation of stainless steel well screen and casing unless the well can. be considered temporary and can be removed within two years. Delta intends to initiate remedial action at the site, including free product recovery, as soon as possible. The proposed monitoring and recovery well installation should give us enough information to design a full scale remedial action plan for this site. ExPerience at other sites has_shown that free product recovery can be completed within approximately one year and that the low level residual contamination can be purged from the aquifer in approximately one additional year of pumping. The anticipated schedule should have the site cleaned up within approximately two years, therefore Delta will install PVC monitoring and recovery wells at the site. An additional reason to install PVC at the site is to maintain consistency in monitoring well construction across the site since there are already six PVC wells currently in use. -:. ..................................

The proposal is not acceptable as written. The following issues must be addressed before approval for implementation may be granted. 1. The workplan was submitted along with a copy of a letter that had been sent to the City of Bakersfield - Department of Public Works. The letter stated an intent to dispose of contaminated water by discharging it to the City of Bakersfield Sanitation Sewer. Tile Kern County Health Department feels that the disposal technique is unacceptable unless the facility can show by ana'lysis -'that the contaminated waters are not hazardous according to Title 22 of the California Administrative Code. '2. The w.orkplan provides an approach for obtaining the horizontal extent 'of contamiaation in groundwater. The vertical extent of contamination is. not addressed. The presence or absence of fuel contaminants in drinking water wells in the area, a search for possible conduits to deeper aquifers in the contaminated area have not been addressed and should be considered. Davies 0il Company February 2, 1988 Page 2 The issues addressed above must be considered and changes to the workplan must be submitted in writing before approval may be granted.

(TCT) TCT TCT Each of these TCT reports contains a brief site history and a description of how and when product losses were detected. The Davies Oil Company is located in a commercial/industrial area northwest of the City of Bakers- field (see Figure 2 for adjacent property owners). The nearest residential area is a small mobil- home park located east of the M.N. and B.K. Goff property, east of the site (Figure 2). Over the course of its investigation, TCT Corporation installed six monitoring wells (MW-1 through MW-4, MW-8, MW-9) and advanced three soil borings (B-5 through B-7). Figure 3 is a.

' I' '"' 1,2 Scope of Work During the period September 23 to December 29, 1987, Delta has completed the following work: 1) A site visit was made in October to measure the depth to ground water, the free-product thick- ness in MW-l, and to collect ground-water samples. 2) Ground-water samples were submitted to the laboratory for analysis of benzene, xylene, toluene, ethylbenzene, ethylene dibromide (EDB), 1,2-dichloroethane (EDC), and total purgeable hydrocar- bons (as gasoline and/or diesel). A product sample was also collected from MW-I and analyzed for total lead content. 3) A site visit was made in December by a California-registered geologist to measure depth to ground 'water and investigate water disposal options. 5) Regulatory agencies were contacted to secure authorization to continue with investigative and remedial activities, including monitoring-well and recovery-well installation, prOduct/water treatment and disposal, and remediation-system construction. This report was prepared, summarizing the results of our work and outlining recommendations for additional ground-water contaminant plume assessment and initial remedial action plans. Davies Oil Company ': Quarterly Monitoring Results ~ Proposed Work Delta Proj~t No. 40-87-$26 Page 9 2,1 ~ite Geoi0e~t 2.0 $.FFE DATA Soil boring logs (Appendix A) indicate the Davies Oil Company site is underlain by fine to coarse, micace~us sand, Silty sand, silt and minor gravel. Local topography and the site's proximity to the present-_day Kern River, indicat_e tha. t_.th?_s..e._.de~0sits are probably of_ Quaternary age ..a!!..d that the_~ deposited in a fluvial or alluvial environment. According to the boring logs, only the upper portion of borings B-.1 through B-4 contain stir; clay layers and potential aquitards were not encountered in any of the soil borings completed at the site. 2.2 Gr0#nd-Water...Elevations an.d Observations Depth to ground water was measured and physical observations recorded at monitoring wells lVlW-2, MW-3, MW-4, MW-g, and MW-9 in October and December (Table 1 ). Product thickness was measured in MW-I in October and in December. Note that the measured elevations are relative to a local assumed 100.00 feet elevation at the side nut of the nearest hydrant on Gulf Street. The top of the water table is currently about 18 feet below grade. A review of the historical ground-water eleva- tion data shows the water table at the site has dropped approximately five feet since July, 1986. Ground-water elevation data indicate ground-water flow is towards the west and southwest. A map of ground-water contours in December, 1987, is presented as Figure 4. 2.7 Ground=Water Quality Ground-water samples collected in October from monitoring wells MW-2, MW-3, MW~.4;- MW-g, and MW-9 were analyzed to determine dissolved concentrations of benzene, toluene, ethylbenzene, xylene, EDB, EDC, and total purgeable hydrocarbons (as gasoline and/or diesel). Table 2 is a summary of the results of these October analyses; laboratory analytical reports are included in Appendix A. Included in Table 2 for comparison are analytical results of water samples collected from the same monitoring wells on May 8, 1987. Note that May samples were analyzed by SMC Laboratory in Bakers- field, and October samples were analyzed by Central Coast Analytical Services in San Lugs Obispo.

Efforts to recover free The high level of total Purgeable hydrocarbons (as gasoline) in MW-9 may also fit with this flow pattern. However, MW-9 is located over 400 feet down-gradient of the leak location. Since the gradient is relatively flat, several years would be required for contaminati6n from the leak location to have reached MW-9. The exact time required depends on the porosity and hydraulic conductivity of the underlying sediments, but under the most favorable conditions, the plume from the identified leak would not be expected to reach MW-9 in less than five years: There is the possibility that as yet~ unidentified sources have contributed to the contamination of Soil and ground water at MW-9. Unless the local ground-water flow gradient is subject to wide seasonal directional variations, the presence of low levels of dissolved hydrocarbons in monitoring wells MW-2 and MW-3 seemingly cannot be explained by transport of contaminants from the known leak locations. Flow gradients determined in December, 1987, indicate that these wells are not down-gradient of the known legk location (especially MW-3). Furthermore, both wells contain at least traces of diesel ~,2 (in a dissolved-~ Phase); product lost at the known leak location was regular-grade gasoline. Contamination of ground ~.c,- water in these two wells may represent a separate leak event at an unidentified up-gradient location," or periodic small surface spills occurring over the yem-s at that location.

(adjacent to the former diesel tank locations--Figure 3) were substantially free of contamination and' since ground-water samples collected from monitoring-well MW-8 (directly down-gradient of the former diesel tank locaiion) have shown no trace of contamination, we believe that any significant soil contamination at this location was removed during the tank excavation process If any con- tamination is present, it may be effectively controlled and removed by remedial efforts in the area of the known leak location. ' 4,0 PROPOSED ADDITIONAL WORK Based on the preceding discussion, we recommend that at least three and possibly four additional monitoring wells be installed at the site. A recovery well will also be installed to (I) determine aquifer parameters, (2) to help prevent further down-gradient movement of the free-product plume, and (3) to initiate free-product recovery at the site. 4.1 Monitoring Well Locations Additional data are required to fully delineate the distribution of contaminants both on and off site. An up-gradient well (MW-10) is proposed near the known leak location (Figure 5). This well is required to confirm the inferred flow direction and to insure that contaminants have not been transported eastward by dispersion. The location of the proposed monitoring well MW-11 was' chosen to determine if there exists a con- ...... tinuous, high level of contamination between MW-I (on site) and MW-9 (off site, down gradient).

Ideally, this well should be located nearer the known point If soil and water samples from both MW- 11 and MW' 12 are contaminated, a fourth well may be neces- sar5' at or near the point marked MW-13 on Figure 5.

However, the intervening property is owned by Mr. Cyril Andre; Mr. Andre has denied previous attempts to gain right-of-entry to his property. We are currently 'negotiating with Mr. Andre for right of entry to his property. If access permission is granted, MW-12 will be moved to a suitable location approximately 100 feet down-gradient of MW-I. 4,1,1 Monitgring Well Svecifications \ The Kern County Health Department now requires that monitoring wells in areas of known contamina- tion be constructed of materials other than PVC. In accordance with this regulation, the proposed monitoring wells will be constructed of 2-inch, flush-threaded, galvanized steel material. The well ~ead will either extend one to two feet above grade or, if installed flush with grade, will be encased in a metal christie box. The wells will be advanced by hollow-stem auger drilling, using methods outlined in Section 5.0. Borehole diameter will be approximately seven inches. All monitor- ing wells will be advanced a minimum of ten feet below the water table; screened intervah will extend approximately five feet above and ten feet below the water table. Actual screened intervals and well depths will be determined in the field by a Delta geologist or engineer. The annulus around the screened interval will be filled with clean, imported gravel. The gravel pack will extend one or two feet above the top of the screened interval. AbOve the gravel pack, a bentonite seal at least two feet thick will be installed. The annular space above the bentonite seal will be grouted to surface. All wells will be equipped with casing bottom plugs and lockable well caps. 4.1.2 Monitorina'-Well Drilline and Develooment Methods 4.1.2.1 Soil Samvle Collection and Screenine One soil sample will be collected from each boring at a depth of 10 feet below grade. Beginning at a depth of 12.5 feet, soil samples will be collected at 2.5 foot intervals to a depth of five feet below the water table. Davies Oil Cornpa~.~* Quarterly Monitorin~ Results & Proposed Work Delt,, Projec~ No. 40-87-3~6 P~ge 17 Upon recovery of the California-modified split-barrel sampler (see Section 5.0), a soil sample will be Collected in a brass tube, capped, packaged and preserved according to UR EP'~-~r°CedU~s for possible chemical analysis. A duplicate sample will be collected in a sealed glass jar and held until completion of drilling activities. All soil samples collected id glass jars will be brought to room temperature and the head space of each jar will be screened for total organic vapors utilizing a portable photoionization detector. Cross sections showing the stratigraphy of the site will be constructed and the results of the soil-sample screening will--b,plotted-on. the cross sections. Based on this information, soil samples may be selected for chemicai analysis to best define the horizontal and vertical extent of contamination. 4,1,2,2 M0nitoring-W~ll Develgpment and Samvlin~ After installation, the monitoring wells will be developed by bailing using dedicated, labora- tory-cleaned teflon balers until field measurements of pH, specific conductance, and temperature' stabilize and the produced water is relatively sediment free. If the well is bailed dry during the development process, recharge rates will be recorded. No water or chemicals will be introduced into the monitoring well during development. Following development, the wells will not be disturbed for approximately two weeks to allow water levels to stabilize prior to obtaining representative ground-water samples. 4.1.3 Chemical Analyses 4,1.3.1 S0il Chemical Analyses Based on' the results of soil-sample screening, soil samples may be selected for chemical analysis. The soil samples will be analyzed for fuel fingerprint, EDB, EDC, BTX, ethylbenzene and total purgeable hydrocarbons by EPA method 524.2/8240 (gas chromatograph/mass spectro- meter selected-ion method or GC/MS SIM). These analyses should indicate whether or not petro- leum contamination has occurred and, if present, will aid in characterization of the type of petroleum contamination (gasoline or diesel fuel).

Rec0,ery-W~ll Inst:~llati0n and PumI~ Test 4,2.1 Rec0very-Well Locagi0n and Installation Because of the presence of free petroleum product in monitoring well MW-I at the site, we propose to install' a product-recovery well at the location indicated on Figure 6. The well will be utilized to perform an aquifer test to calculate aquifer parameters and determine if addi- tional recovery wells will be required, and where they should be located. Information will be collected °n flow rates and ground-water quality to determine the design of a water-treatment system. The well will then be utilized to recover free product and to establish gradient control to prevent movement of product plume. 4.2,2 Recovery-Well Sl~ecifications The recovery well will be drilled to a total depth of 35 feet. We recommend that the well be completed with 12-inch casing to allow clearance for a down-hole, dual-pump system. The borehole would be 20 inches in diameter, leaving a 4-inch annular space to insure adequate gravel-pack thickness. We recommend use of a #40 slot (0.040"), continuous galvanized screen. The screen should be 20 feet in length and should be set between 17 and 37 feet below grade. Gravel-pack material should consist of uniformly graded, coarse sand (Monterey g3 or equiva- lent), and should extend 3 or 4 feet above the screened interval. See Figure 6 for typical recovery-well construction specifications. 4.2.3 Aouifer Test Soecifications After the reco.very well is installed and fully developed, an extended pump test will be con- ducted to determine the long-term yield of the well and to determine aquifer parameters Davies Oil Company Quarterly Monitorin~ Results & Proposed Work Delta Project No. 40-$7-326 Page 19 NOTE: NOT TO SCALE. 12" STEEL WELL CASING STATIC WATER LEVEL 18' BELOW GRADE '-' 12", CONTINUOUS SLOT, ,P40, GALVANIZED STEEL WELL SCREEN 20" BORE HOLE --CLEAN IMPORTED GRAVEL PACK 4'° ANNULUS PROPOSED RECOVERY WELL DESIGN DELTA NO. 40-87-326 DATE 12/87' FIGURE 6 Consultant'% Davies Oil Company Quarterly Monitoring Results/z Proposed Work Delta Project No. 40-87-326 Page 20 (hydraulic conductivity and storativity).

"t,: Treatment and disposal of water produced by recovery wells is a primary design consideration. '. ......................... After an initial' investigation, it is-.-apparent that .-three- water-disposal - options exist:-These . options are: 1) discharge to existing storm sewer, 2) infiltration or injection on site, and ~" 3) discharge to existing sanitary sewer. ~.>\, ~b, ~ Option l, discharge' to an existing storm sewer, would require that a National Pollutant Dis-~ charge Elimination System (NPDES) permit be secured from the U.S. EPA. Water discharged to a storm sewer would likely need treatment, using the best available technology, to high standards (possibly drinking-water standards) under the terms of an NPDES permit. Extensive monitoring of the quality of the discharge water would also be required. During a December field visit, it was observed that no nearby storm sewers are available. Storm water in the area is apparently controlled by surface run=off· On=site infiltration (Option 2) may also be an acceptable option..Water to be re=injected or allowed to infiltrate may also require treatment to near=drinking water standards. Compliance with such standards may require installation of expensive and maintenance-intensive treatment equipment on site, In addition, chemical constituents that may occur naturalIy in the water (iron, carbonate) and bacterial components may have to be removed to prevent plugging of the infiltration gallery. Option 3, discharge to an existing sanitary sewer, seems to be a practical solution. A City of Bakersfield sewer line is located approximately 750 feet southeast of the site. However, the Bakersfield Department of Public Works (DPW) has indicated a reluctance to allow discharge of produced water to the sewer. The city requires that any discharge to' the sewer must be cert- ified by the California State Department of Health Services (DHS) as 'non-hazardous' under the requirements of the Califo.rnia Administrative Code, Title 22, Division 4, Chapter 30, Article 11. An official in the DHS, Alternative Technologies Division, indicated that such certifica- Davies Oil Company. Quarterly Monitorin~ Results ~z Proposed Work Del~;a Projec~ No. 40~87-326 Page 21. tion normally takes at least one year to complete. Only after the discharge is certified as non-hazardous will the Bakersfield DPW consider allowing the discharge in{o'-t~:-Sanitary sewer. However, officials at the DPW will not guarantee that the discharge water will be allowed to enter the sanitary sewer, even if it is classified as a non-hazardous waste. · - ............ Delta representatives' will continue to-work With the City of Bakersfield; the-California'Depart- '.. ment of Health, and the San Joaquin District of the Regional Water Quality Control Board to insure that the water discharge will be disposed of in a mutually-acceptable manner. (. ~;.0 METHODS All field work, data analysis and interpretation will be conducted under the supervision of a California Registered Geologist. 5.1 Soil Samoline and Conta, mination ·Reduction Monitoring=well drilling and soil sampling will be performed under the direction of a Delta engineer or geologist. The monitoring wells will be advanced using a truck=mounted hollow-stem auger drill rig. Upon recovery, a portion of the soil sa~nple will be placed into a glass jar and sealed for later screening with a photoionization detector. Another portion of the soil sample will be used for classification and description. That part of the soil sample collected in brass tubes within the California-type sampler will be stored at approximately 4° C. for transport to the laboratory.

If the well is bailed dry during the develop- meat process, recharge rates will be recorded. No water or chemicals will be introduced into the monitoring wells during well development. Ground-Water Samulin~ Following well development, and after water levels have been allowed to stabilize in the well, three to five volumes of liquid will be removed from each well by pumping or bailing. Measurements of pH, specific conductance, and temperature will be made at regular intervals during this procedure. Removal of liquid from each well will continue until the measured pH, specific conductance, and temperature have stabilized. A liquid sample will then be collected from each well with a labora- tory-cleaned, dedicated teflon bailer. Each sample will be appropriately labeled and stored in ice from the time of collection through the time of delivery to the laboratory. $.~ Pegroieum Product If free petroleum product is present in a well, the thickness of the product layer will be measured by collecting a sample in a transparent teflon bailer with a check valve at' the bottom or by Davies Oil Company quarterly Monitoring l?~sults & Proposed Work Delta Project No. 40-87-326 measurement using appropriate fluid-level sounding equipment.

Each sample will'be collected in a suitable container, preserved correctly for the intended analyses, and stored prior to analysis for no longer than the maximum allowable holding time. Details on the procedure for collec- -tion and handling of soil and ground-water samples to be used on this project can be found in Section 4.0. Davies Oil Company Quarterly Mon/~-or/ng Resul~a & Proposed Work Delta Project No. 40-87-326 Page ~4 7,2 Sample Identification and Chain-of-Custody procedures Sample identification and chain-of-custody procedures ensure sample integrity and document sample possession from the time of collection to its ultimate disposal. Each sample container submitted for analysis will have a label affixed to identify the job number, sampler, date and time of sample collec-tion, and a sample number unique to that sample.' This information, in addition to a descrip- tion of the sample, field measurements made, sampling methodology, names' of on-site personnel;-and any other pertinent field observations will be recorded on the borehole log or in the field records. All samples will be analyzed by Central Coast Analytical Services (CCAS) in California. A chain-of-custody form will be used to record possession of the sample from time of collection to its arrival at the laboratory. When the samples are shipped, the person in custody of them will relinquish the samples by-signing the chain-of-custody form and noting the time. The sample-control officer at CCAS wilI verify sample integrity and confirm that it was collected in the proper con- tainer, preserved correctly, and that there is an adequate volume for analysis. If these condilions are met, the sample will be assigned a unique log number for identification throughout analysis and reporting. The log number will be recorded on the chain-of-custody form and in the legally-required log book maintained by CCAS in the laboratory. The sample description, date received, client's name, and any other relevant information will also be recorded. 7.3 Ana!vtical Quality Assurance In addition to routine calibration of the analytical instruments with standards and blanks, the analyst (CCAS) is required to run duplicates and spikes on 10 percent of the analyses to insure an added measure of precision and accuracy. Accuracy is also verified through the following: I) U.S. Environmental Protection Agency (EPA) and State certification programs. 2) Participation in an inter-laboratory or "round-robin" quality assurance program.

The objective of the plan is to describe procedures and actions to protect the worker, as well az uninvolved parties, from inhalation and ingestion of, and direct skin contact with, potentially hazardous materials that may be encountered at the site. The plan des- cribes 1) personnel responsibilities, and 2) protective equipment to be worn as appropriate when working on the site. $.1 Personnel Responsibilities, Key personnel directly involved in the investigation who will be responsible for monitoring the execution of safe-work practices and the Provisions of this plan are 1) the drilling-subcontractor project supervisor and 2) the Delta project field manager. These personnel are responsible for knowing the provisions of the plan, communicating plan requirements to workers under their super- vision and to site visitors, and for enforcing the plan.

To prevent direct skin contact, the Follow- ing protective clothing will be worn as appropriate while working at the site: 1) Hard hat with optional face shield 5) Goggles or safety glasses (if optional Face shield not used on the hard hat) The type of gloves used will be determined by the type of work being performed. Drilling personnel will be required to wear butyl rubber gloves because they will have long-duration contact with the subsurface materials. Delta sampling personnel will wear disposable gloves when handling any sample. These gloves will be changed between each sample. Personnel-protective equipment shall be put on before entering the immediate work area. The sleeves of the coveralls shall be outside of the cuffs of the gloves to facilitate removal of clothing with the least potential, contamination of personnel. If at any time protective clothing (coveralls, boots or gloves) becomes torn, wet, or excessively soiled, it will be replaced immediately. No eating, drinking, or smoking will be allowed in the vicinity of the drilling operations. Delta will designate a separate area on site for eating and drinking. Smoking will not be allowed at the vicinity of the site except in designated areas.
