March 17, 1989 Reevaluation of the Preliminary Assessment of Pacific Gas and Electric Bakersfield Service Center, 4101 Wible Road, Bakersfield, California, Kern County, dated August 6, 1980 CAD980816359 FCA0874PAA Christine Houston, Ecology and Environment, Inc. ~~ FIT Mas ter File Chris Lichens, Ecology and Environment, Inc. Don Plain, California Department of Health Services, Sacramento William Pfister, Central Valley Regional Water Quality Control Board, Fresno Richard Casa Grande, Kern County Environmental Health, Bakersfield Ralph Huey, Bakersfield Fire Department, Hazardous Materials Unit, Bakersfield Under Technical Directive Document number F9-8809-079, Ecology and Environment, Inc.'sField Investigation Team (FIT) has been tasked to reassess all Preliminary Assessments (PAs) in the Comprehensive Environmental Response, Compensation, and Liability Information System (CERCLIS) with "active" or "pending" status according to the guidelines established to implement the Superfund Amendments and Reauthorization Act (SARA). During the course of this reassessment process, PAs were identified that contained insufficient information to allow for an accurate reassessment. FIT has been subsequently directed reevaluate and upgrade these PAs as needed to ensure that an accurate response determination is made. The strategy for determination of further action under the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) is based solely on each site's potential to score high enough on the Hazard F09S e - Ranking System (HRS) for inclusion on the National Priorities List (NPL). This strategy is intended to identify those sites posing the highest relative risk to human health or the environment. All other sites needing remedial or enforcement follow-up will be referred to the States or other appropriate Federal agency. This site was evaluated primarily using the original HRS model. Additionally, this site was also evaluated for its potential to score using the proposed revised HRS model. The following is a summary of FIT's findings with regard to this site. SUMMARY The Pacific Gas and Electric (PG&E) Bakersfield Service Center is located at 4101 Wible Road, Bakersfield (Kern County), California (1). The Service Center is a maintenance and operations center for PG&E in the Bakersfield area. The PG&E facility consists of an operations/ administration building, several smaller buildings (use unknown), a parking lot for PG&E vehicles, and an outside storage area (as observed by FIT on October 10, 1988). PG&E management was made aware of possible buried PCB capacitors at the Bakersfield facility in mid-1980. A preliminary site investigation was initiated by PG&E at that time which confirmed that PCB capacitors and other construction debris had been placed in a depressed area of the facility grounds. It is believed by PG&E officials that the PCB capacitors found at the Bakersfield Service Center were placed on-site in the late 1960s and/or early 1970s. Subsequently, the site investigation was expanded and appropriate remediation plans were developed. Site investigation and remediation activities included soil sampling and analyses for site characterization, removal and proper disposal of all PCB articles (895 capacitors, less than nine tons of PCB contaminated oil), removal of associated contaminated soil, placement and compaction of clean backfill in excavated areas, and installation of a soil cement and asphaltic concrete cap over the entire facility. The site remediation was completed in May 1985. All PCB site investigation and remediation activities at the Bakersfield Service Center were performed under the direction of and with the concurrence of the California Department of Health Services (DOHS) (2). PCB contaminated soils have been removed from the site, which was then backfilled and capped with asphaltic concrete, precluding the possibility for documenting an observed release to air attributable to PG&E. The nearest surface water is a tributary to the Farmers Canal found 3000 feet south of the site. The Farmers Canal is an agricultural delivery canal connected to a series of canals that services the South Bakersfield area with irrigation water. These canals serve over 10,000 acres (exact figure unknown). The slope of the facility and intervening terrain is less than three percent (3). The one-year, 24-hour rainfall is less than one inch (4). No sensitive environments exist within a four-mile radius F09S . . of the site. The closest well to the site is within a quarter mile of PG&E. This well is a municipal well owned by the California Water Service Company. Water from this well is blended and serves over 10,000 people. The depth to this aquifer is greater than 150 feet below surface level. The unsaturated zone consists mainly of clays with intervening layers of sand (5). A Preliminary Assessment completed by EPA on August 6, 1980 recommended a high priority Site Inspection based on the presence of PCBs. FIT does \not concur. A preliminary HRS screening estimate of PG&E indicates that it will probably not qualify for inclusion on the NPL based on the following HRS factors: (1) depth to the aquifer of concern (greater than 150 feet); (2) low net precipitation (less than one inch); (3) low permeability of the unsaturated zone (clays); (4) low waste quantity (less than nine tons); (5) low potential for release to surface water (the slope of the facility and the intervening terrain is less than three percent); (6) no sensitive environments exist within a four-mile radius of the site; and (7) low potential for an observed release of hazardous materials to air because the PCB contaminated soils have been removed and the site was capped with asphaltic concrete. CONCLUSIONS Based on the following factors, the Pacific Gas and Electric Bakersfield Service Center does not appear to be eligible for inclusion on the National Priorities List: o depth to the aquifer of concern (greater than 150 feet); o low net precipitation (less than one inch); o low permeability of the unsaturated zone (clays); o low quantity of waste (less than nine tons); o low potential for release to surface water (the slope of the facility and the intervening terrain is less than three percent); o no sensitive environments exist within a four-mile radius of the site; and o PCB contaminated soils have been removed from the site, which was then backfilled and capped with asphaltic concrete, precluding the possibility for documenting an observed release to air attributable to Pacific Gas and Electric.

(Twining) has prepared this report of abandonment of the Class V Shallow Injection Well at the Pacific Gas and Electric Company (PG&E) Bakersfield Service Center, at your request. The abandonment was performed under PG&E Job Order number 036436. This report includes a project background and a description of the abandonment procedures. ' BACKGROUND The site is in the southeast quarter of Section 14, Township 30 South, Range 27 East, Mount Diablo Baseline and Meridian. The site is currently occupied by the PG&E Bakersfield Service Center (Drawing 1). According to the United States Department of Interior, Bureau of Reclamation (1993), grOundwater in the area of the site was at a depth of approximately 190 feet in the spring of 1993 and flows generally to the east (U.S. Bureau of Reclamation, 1993). A vehicle wash rack is located on the eastern edge of the vehicle maintenance building (Drawing 2). Prior to 1993, rinseate from the wash rack was collected in a drain and then piped through an oil/water separator into three dry wells. The dry wells are reportedly 10 to 15 feet deep. In 1993, PG&E installed a closed rinse ate recovery system that collects rinseate for recycling. Piping to the dry wells was disconnected at that time. In April 1993, The Kern County Environmental Health Services Department (KCEHSD) requested that PG&E perform a preliminary investigation of the former rinseate disposal system with the goal of closing the system according to United States EnVironmental Protection Agency (U.S. EPA) guidelines.

Twining prepared the work plan (Twining, 1993b) and proposed drilling one soil boring near e Ie Pacific Gas and Electric Company October 26, 1994 TLP 393-0161-04a Page 4 one of the dry wells. The KCEHSD approved the work plan with the condition that the samples were to be analyzed for total recoverable petroleum hydrocarbons (TRPH) instead of total petroleum hydrocarbons-diesel range (TPH-D) and with the understanding that additional work may be required. In December"1993 Twining drilled and sampled one boring (B-1) approximately three feet east of the eastern most dry well (Drawing 2). The location was approved in the field by the KCEHSD on-site representative. Soil boring B-1 was drilled to a depth of approximately 25 feet below surface grade (BSG). Soil samples were collected at 5-foot intervals, beginning at a depth of 5 feet BSG. Soil samples were examined for visual evidence of petroleum hydrocarbons, and screened for evidence of volatile organic compounds (VOCs), using a photoionization detector (Pill). Soil samples from B-1 were analyzed by Twining for TRPH using U.S. EPA Method 418.1 (U.S. EPA, 1984). Soil sample analytical results are summarized on Table 3. The laboratory analytical report and chain-of-custody documents are presented in Appendix C. Table 3 Summary of Soil Samole Analytical Results Borin~ B-1.

Only one sample contained a detectable concentrations of TRPH, however, analysis of the sample collected .5 feet below it was none detected. On the basis e Ie Pacific Gas and Electric Company October 26, 1994 TLP 393-0161-04a Page 5 of the exploratory field investigatio~. and the laboratory analytical results, Twining concluded soils in the vicinity of the Class V shallow injection well have been impacted by petroleum product constituents. However, because the bottom sample (24.5 feet BSG) was none detected and groundwater is reported to be approximately 190 feet BSG, the petroleum hydrocarbons detected do not appear to be a threat to groundwater quality. In a letter dated February 17, 1994, the KCEHSD stated that based on the analytical results from B-1, "no remediation or additional sampling is needed for the shallow injection system area at this site." The letter also stated that the system could be removed or cleaned and abandoned in place.' Twining's prepared a "Work plan for Abandonment of Class V Shallow Injection Well, Bakersfield Service Center," dated August 4, 1994. The proposed scope of work was based on the requirements included in the KCDEHS "Closure of Shallow Disposal Wells",(SDW- 110), undated, and on discussionS with Ms. Dolores Gough of the KCEHSD. The KCEHSD approved the work plan on August 22, 1994. DESCRIPTION OF SYSTEM ABANDONMENT I I Twining performed the disposal well system abandonment on September 29, 1994. Ms. Lydia Von Sydow of the KCEHSD was onsite throughout'the abandonment procedures.

Twining conducted a site reconnaissance on' August 5, 1993 and samples of the liquid and sludge present in the oil-water separator were collected in the presence of a KCEHSD representative. The water sample appeared to have a slight petroleum odor and visible sheen. The samples were chemically analyzed for constituents specified by Mr. Terry Gray of the KCEHSD. The analytical methods and results are summarized in Tables 1 and 2.

Only one sample contained measurable TRPH, however, and the analytical results for the sample collected 5 feet below it was none detected. On the basis of the exploratory field investigation, and the laboratory analytical results, Twining concluded soils in the vicinity of the Class V shallow injection well have been impacted by PPC's. However, because the bottom sample (24.5 feet BSG) was none detected and groundwater is reported to be approximately 190 feet BSG, the petroleum hydrocarbons detected do not appear to be a threat to groundwater quality. In a letter dated February 17, 1994, the KCEHSD stated that based on the analytical results from B-1, "no remediation or additional sampling is needed for the shallow injection system area at this site." The letter also stated that the system could be removed or cleaned and abandoned in place. PROPOSED SCOPE OF WORK Twining's proposed scope of work is based on the requirements included in the KCDEHS "Closure of Shallow Disposal Wells",(SDW-lOO), undated and on discussions with Ms. Dolores Gough of the KCEHSD. The proposed scope of work includes the following tasks: · Removal of remaining liquid and sludge in the system. PG&E will dispose of the material in accordance with applicable Federal" State, and local guidelines; · Steam-cleaning of the remaining system piping; · Capping of the system piping between the collection sump and oil/water separator and between the diverter sump and drywells; · Filling of the sumps and oil/water separators with sandi cement slurry; · Filling the three drywells from the bottom up with sandi cement slurry; · Preparation of a report of abandonment for submittal to the KCEHSD.

Your letter indicates that potable (domestic) water will be used and that no additives or wastes will be added to the water. Past tests of hydrostatic test waters sent by you have revea1ed no significant pollutants. We do not concur that this discharge does not constitute a discharge of waste. We requested and you have subsequently submitted a report of waste discharge and filing fee. Therefore, provided you receive approval from the property owner to discharge on its land and comply with the following procedures, we hereby waive waste discharge requirements. Following cûmpletion of the hydrostatic test, the water used for testing will be tested for quality and, if constituents of concern are not detected, discharged to land adjacent to Buena Vista Road. The results of the laboratory analysis of the discharge must be sent to the Regional Board. If you have any questions concerning this matter please contact Kevin Long at (209) 445-5548. WilLIAM H.

DRILLING SERVICES CONSTRUCTION INSPECTION & MATERIALS TESTING September 16, 1993 TL 393-0161-01 I Mr. Dennis White Pacific Gas and Electric Company Kern Division 1918 H Street Bakersfield, California 93301 Re: Results of Wash Rack Sump Sampling Bakersfield Service Center Dear Mr. White: The Twining Laboratories, Inc. (Twining) has prepared this letter to report the sampling and analysis of liquid from a sump near the vehicle wash rack at the Pacific Gas and Electric Company (PG&E) Bakersfield Service Center. The sampling was performed based on a reqùest from Mr. Tom O'Brien of PG&E. Until the Spring of 1993, liquid from the vehicle maintenance wash rack was disposed of through a system of collection sumps, oil-water separator, and drywells. The drywell disposal system has been replaced by a "closed" system which recycles the wash water. FIELD OBSERVATIONS AND SAMPLING PROCEDURES Twining collected liquid samples from what appeared to be an oil-water separator on August 5, 1993. Mr. Terry Gray of the Kern County Environmental Health Services Department (KCEHSD) was present during the sampling and specified the location and number of samples. Twining collected samples of the liquid present in the oil-water separator using a clean disposable bailer. We also collected a sample of the underlying sludge within the separator with a clean stainless steel sampler. The samples were transferred to clean laboratory supplied containers for shipment to Twining's analytical laboratory. liquid within the oil-water separator appeared to have a petroleum-like sheen and had a slight petroleum odor.

No investigation is thorough enough to exclude the presence of hazardous materials at a given site. If hazardous conditions have not been identified during this assessment, such a finding should not therefore be construed as a guarantee of the absence of such materials at the site, but rather as the result of the services performed within the scope, limitations, and cost of the work performed. This work was performed for the sole use of the client and appropriate regulatory agencies. Any reliance on this report by a third party is at such a party's sole risk. CLOSING Twining appreciates the opportunity to provide these services, to PG&E. If you have any questions regarding this report, please contact Twining at (209) 625-1712.

A laboratory control sample is generated by spiking the analyte into a, relatively inert matrix (clean sand or blank water). The laboratory control sample is analyzed exactly like a sample, and its purpose is to determine whether the methodology is in control and whether the laboratory is capable of making accurate and precise measurements.

Elias, Kern Division Manager PACIFIC GAS AND ELECTRIC 1918 H Street' Bakersfield, CA 93301 Dear Mr. Elias: The purpose of this letter is to memorialize my discussions with Russell Messick and our subsequent agreement regarding the method and manner in which P.G.& E. will address unplanned releases of materials containing PCB from electrical utility equipment into the environment. This letter will replace our previous direction on this subject dated November 16, 1982. REPORTING All releases of insulating fluid where the PCB concentration cannot be determined by reference to a manufacturer's tag, or sticker and those where reference to the tag or sticker indicates PCB concentration .2:,5 ppm shall be reported to the Kern County Environmental Health Services Department. Where reference to a manufacturer's sticker/tag or a P.G.& E. repair facility tag on the outside of a transformer or other piece of electrical equipment definitely confirms that the equipment contains No PCB or <5 ppm PCB no report to Kern County Environmental Health Services Department is required. The report of release should be made as soon as is practicable after the arrival of P.G.&E. supervisor on- scene. The reporting party should be prepared to give the location of the spill, the approximate amount of fluid spilled and whether the concentration of PCB has been determined by reference to a tag or sticker. In instances where fire or a traffic accident is involved to cause the release, it is likely the Department will have received notif ication from a 911 responding agency. However, unless contact is made with Department personnel on scene, the first arriving P.G.& E. personnel should make a confirming call as above. 2700 "M" STREET, SUITE 300 BAKERSFIELD, CALIFORNIA 93301 PRJNlE) ON RECYClED PAPER (805) 861·3636 FAX: (805) 861·3429 e e Paul D. Elias September 13, 1991 Page 2 I ! Notification calls 'during working hours should be directed to Kern County Environmental Health Services Department at (805) 861-3636 After hours, weekends and holidays calls should be directed to: Kern County Communications, Control 5, at (805) 861-2500. ANALYSES All releases of insulating fluid from equipment not labeled as Non-PCB or <5 ppm PCB should be tested by a licensed hazardous waste laboratory using the appropriate gas chromatograph method. The timing of the analysis, whether emergency rush or routine, should be determined in consultation with the on-call Hazardous Materials Specialist. Factors to be considered include: amount spilled, location, and public access. In general, an emergency rush sample is preferred, however, a small quantity release in a rural area which can be secured without detriment to the public or the environment may be a candidate for routine testing and clean-up the next regular working day. The results of any testing performed are to be communicated to the Environmental Health Services Department upon receipt. CLEAN-UP In California clean-up of liquid waste containing ~5 ppm PCB is required. ,The adequacy of a clean-up will be judged by analyzing post-clean-up sample results and comparing them to criteria established for a particular site based on its potential to affect human health or the environment. The general clean-up levels outlined below can be expected to apply in the absence of extenuating circumstances as determined by the Environmental Health Services Department.

M.D. /' DIRECTOR OF ENVIRONMENTAL HEALTH Vernon S. Reichard -/J!z November 16, 1982 Michael Moore ager G and Electric Company 19l&, treet Bakersfield, California 93301 Dear Mr. Moore: This letter shall address the Kern County Health Department, Division of Environmental Health, policy regarding capacitor or transformer oil spillage. This policy is consistant with the "Hazardous Materials Incident Contingency Plan" used by the California Highway Patrol and which was agreed to by all state and local governmental agencies in Kern County. It appears that since P.G.& E. does not have records at this time to verify whether or not a piece of equipment contains P.C.B. prior to its' spillage, the untimely spillage would in fact fall under the category of a chemical spill as addressed in the plan described above The plan requires anyone who is aware of such a spillage to immediately notify the proper authorities; in these cases the referral should be made to either the Kern County Health Department at 861-3636, or directly to the California Highway Patrol. We then will notify the agencies needed per the plan; however, emergency agencies such as fire or ambulan¡ or other police agencies are to be called upon at your discretion or as company policy dic- tates as being necessary for each incident. Our experience has shown that P.G.& E. has the facilities, equipment, and personnel to answer emergency calls for equipment leakage to facilitate securing the area, taking and processing samples, and site clean-up and decontamination prior to disposal of any and all contaminations. It appears that the company has used two alternatives that are consistent with our analysis of risk assessment: I, 1) Immediate sampling of the oil for analysis prior to securing the spillage area with barricades and constant surveillance by authorized P.G. & E. personnel to prohibit entry; based on the timely lab response, P.G. & E. would know whether to start site clean-up or not. !' A F+€: IL hoc...uu Slø I - 2..15:'00 ." e e --- f', . ..'''... .' ~ I: Michael Moore Page Two November 16, 1982 I: 2) Immediate sampling of the oil for analysis and the proper site clean-up and contamination storage prior to disposal based on the analysis submitted. I: Since the Health Department's concerns are addressed by either of the alternatives above, the choice is clearly one for P.G. & E. to make on a case-by-case basis. Our personnel have been instructed to assist you at the scene in relaying information to the Incident Commander, normally California Highway Patrol, police department, or sheriff's department personnel. We have further instructed our personnel they may leave the scene once P.G. & E. verifies the method used for addressing our concerns and that method is initiated to their satisfaction. However, should decontamination be necessary, the Kern County Health Department should monitor the scene until the decontamination is completed so that we may state when the scene is safe again as required by the California Highway Patrol Plan. Should you have any questions regarding Kern County Health Department policy, the California Highway Patrol Plan, or individual incidents, we will be most willing to meet with you, as we look forward to working with your company in areas of mutual interest.

SOLUTION: Build a computer based program to document known PCB concentration levels for oil filled equipment. This program could be done on a local level or preferably on the system level through LANíWAM. Work with local and state agencies on their acceptance of known PCB concentration levels identified through 1) manufacturer's name plate (Attachment 1), 2) manufacturer's non PCB stickers, blue, (Attachment 2), 3) PG&Erepaired sticker (silver with blue lettering), code 1428, (Attachment 3 8.; 4). A summary of T&D Bulletin 2-50 identifies the categories of PCB concentration for solid and liquid mediums in parts per million (ppm) '::\ ~5 : PCB F'C:B ~l)l) pptn or qv"'ea"ter contaminated, 50-499 ppm less t!'''¡¿'In 50 ppfii t'·,~ Ct n F: C: B Oil filled electrical equipment with an unknown PCB concentration must be assumed to be PCB contaminated (50-499 ppm) until tested or proven clther\A.li '5e. Ir¡ -[,he St¿;lte Df Califor'nia, all "waste" liquids:, c:ont¿lininq from 5 ppm to less than 50 ppm PCB are considered a long-term environmental risk and. therefore, regulated as a hazardous waste, for disposal purposes. All used "w,:o.',,;te" oi 1 ',;;, r-egard 1 ess of thei r- PCB concentrat ion ar-e no¡;., considered a hazardous waste in California. All retr- i evab 1 e 1 i qui d "waste" wi th 5 ppm or- greater, and all sol i d wastes containing 50 ppm or greater, PCB must be removed from the environment. Clean-up levels lower than those specified above may be necessary on a case-by-case basis, where there is likelihood of direct and repeated human or animal contact, where food chains may be endangered, or where water resources (including swimming pools), may beco~e contaminated. Regardless of the PCB concentration, at least visible traces of spilled mineral oil and synthetic insulating fluid(s) ~ust be removed from the environment. On all transformers and other oil filled equipment received from the manufacturers since approximately 1985, the PCB concentration level was identified at the time of manufacture on either the name plate data, the blue non-PCB sticker, or both. On all transformers or other oil filled equipment, tested and/or rebuilt by equipment repair facilities throughout the PG&E system, all insulating fluids are gas chromatograph tested for PCB concentration levels by PG&E and State approved labs. The test results are logged both at the repair facility and 6n the PG&E repaired I. sticker attached to the equipment. There does not seem to be a standard e e Page 2 way of filling out this tag, as shown in the photos of Attachment 3. This procedure needs to be "tied down" with each repair facility identifying 1) manufacturer and serial number, 2) repair facility identification, 3} date tested and lab, 4) date retrofilled, if applicable, and type of oil/insulating fluid, 5) type of test (gas chromatograph or other), i' 6) the PCB concentra,tion level, ppm. As indicated on the tags, (At tachment 3), 4) 1) non PCB, less than 50, another test will have to be taken to determine EXACT ppm. less than 50 ppm, same as above. 3) content ppm blank - same as no test, assumed to be PCB contaminated (50-499 ppm). content ppm 8T-61 8 ppm, indicates spill will have to be cleaned up to less than 5 ppm. content ppm - ND (none detected) mean 0 ppm. No clean-up procedure required except all visible traces of oil removed. 2} t:.,- '. J} :::~;E°C: t i:m 1,- D ( T ;~d) I-?u 11 f?t i n :2,-:')) '!

During the course of this reassessment process, PAs were identified that contained insufficient information to allow for an accurate reassessment. FIT has been subsequently directed reevaluate and upgrade these PAs as needed to ensure that an accurate response determination is made. The strategy for determination of further action under the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) is based solely on each site's potential to score high enough on the Hazard F09S e e Ranking System (HRS) for inclusion on the National Priorities List (NPL). This strategy is intended to identify those sites posing the highest relative risk to human health or the environment. All other sites needing remedial or enforcement follow-up will be referred to the States or other appropriate Federal agency. This site was evaluated primarily using the original HRS model. Additionally, this site was also evaluated for its potential to score using the proposed revised HRS model. The following is a summary of FIT's findings with regard to this site. SUMMARY The Pacific Gas and Electric (PG&E) Bakersfield Service Center is located at 4101 ~ible Road, Bakersfield (Kern County), California (1). The Service Center is a maintenance and operations center for PG&E in the Bakersfield area. The PG&E facility consists of an operations/ administration building, several smaller buildings (use unknown), a parking lot for PG&E vehicles, and an outside storage area (as observed by FIT on October 10, 1988). PG&E management was made aware of possible buried PCB capacitors at the Bakersfield facility in mid-1980. A preliminary site investigation was initiated by PG&E at that time which confirmed that PCB capacitors and other construction debris had been placed in a depressed area of the facility grounds. It is believed by PG&E officials that the PCB capacitors found at the Bakersfield Service Center were placed on-site in the late 1960s and/or early 1970s. Subsequently, the site investigation was expanded and appropriate remediation plans were developed. Site investigation and remediation activities included soil sampling and analyses for site characterization, removal and proper disposal of all PCB articles (895 capacitors, less than nine tons of PCB contaminated oil), removal of associated contaminated soil, placement and compaction of clean backfill in excavated areas, and installation of a soil cement and asphaltic concrete cap over the entire facility. The site remediation was completed in May 1985. All PCB site investigation and remediation activities at the Bakersfield Service Center were performed under the direction of ' and with the concurrence of the California Department of Health Services (DOHS) (2). PCB contaminated soils have been removed from the site, which was then backfilled and capped with asphaltic concrete, precluding the possibility for documenting an observed release to air attributable to PG&E. i The nearest surface water is a tributary to the Farmers Canal found 3000 feet south of the site. The Farmers Canal is an agricultural delivery canal connected to a series of canals that services the South Bakersfield area with irrigation water. These canals serve over 10,000 acres (exact figure unknown). The slope of the facility and intervening terrain is less than three percent (3). The one-year, 24-hour rainfall is less than one inch (4). No sensitive environments exist within a four-mile radius I: F09S e I I , I e of the site. The closest well to the site is within a quarter mile of PG&E. This well is a municipal well owned by the California Yater Service Company. Yater from this well is blended and serves over 10,000 people. The depth to this aquifer is greater than 150 feet below surface level. The unsaturated zone consists mainly of clays with intervening layers of sand (5). A Preliminary Assessment completed by EPA on August 6, 1980 recommended a high priority Site Inspection based on the presence of PCBs. FIT does ~not concur. A preliminary HRS screening estimate of PG&E indicates that it will probably not qualify for inclusion on the NPL based on the following HRS factors: (1) depth to the aquifer of concern (greater than 150 feet); (2) low net precipitation (less than one inch); (3) low permeability of the unsaturated zone (clays); (4) low waste quantity (less than nine tons); (5) low potential for release to surface water (the slope of the facility and the intervening terrain is less than three percent); (6) no sensitive environments exist within a four-mile radius of the site; and (7) low potential for an observed release of hazardous materials to air because the PCB contaminated soils have been removed and the site was capped with asphaltic concrete. CONCLUSIONS Based on the following factors, the Pacific Gas and Electric Bakersfield Service Center does not appear to be eligible for inclusion on the National Priorities List: o depth to the aquifer of concern (greater than 150 feet); o low net precipitation (less than one inch); o low permeability of the unsaturated zone (clays); o low quantity of waste (less than nine tons); o low potential for release to surface water (the slope of the facility and the intervening terrain is less than three percent); o no sensitive environments exist within a four-mile radius of the site; and o PCB contaminated soils have been removed from the site, which was then backfilled and capped with asphaltic concrete, precluding the possibility for documenting an observed release to air attributable to Pacific Gas and Electric.

Revision No.5. "Handling. Marking. Inspecting. Reponing and Spill Cleanup for PCB-Filled. PCB-Contaminated. and Oil-Filled Electrical Equi,pment". For references. see Bulletin Supplement Section A. I-B. GENERAL The categories of PCB concentration for solid and liquid mediums in parts per million (ppm) are PCB (500 ppm or greater). PCB-contaminated (50-499 ppm). and non-PCB (less than 50 ppm). Oil-filled electrical equipment with an unknown PCB concentration must be assumed to be PCB-contaminated until tested or proven otherwise. In the state of California. all "waste" liquids containing from 5 ppm to less than 50 ppm PCB are considered a long-term environmental risk and therefore regulated as a hazardous waste for disposal purposes. All, used "waste" oils. regardless of their PCB concentration. are now considered a hazardous waste in California. Spills involving 50 ppm or greater PCB have been classified into two 'major spill categories ofIow- and high-concentration PCB spills. A low-concentration PCB spill is assumed or identified as containing less than 500 ppm PCB. whereas a high-concentration PCB spill is identified as containing 500 ppm or greater PCB. Regardless of the concentration. spills that release the equivalent of 1 pound or greater of pure PCB by weight are defined to be high-concentration PCB spills. All retrievable liquid "wastes" with 5 ppm or greater and all solid wastes containing 50 ppm or greater PCB must be removed from the environment. Cleanup levels lower than those specified above may be necessary on a case-by-case basis where there is likelihood of direct and repeated human or animal contact; where food chains may be endangered; or where water resources. including swimming pools. may become contaminated. The general cleanup criteria for the different PCB insulating fluid spill categories are as follows: · Remove all retrievable liquid "wastes" (e.g.. oil cleanup solvents and oil/water mixtures) with 5 ppm or greater PCB from the environment. . Remove all contaminated solid "wastes" (e.g.. soil. rags. absorbent material. and vegetation) that have absorbed liquids containing 50 ppm or greater PCB. The specific cleanup criteria for "low-concentration PCB spilJs" and "high-concentration PCB spilJs" are detailed under PCB Spill Cleanup. . Cleanup levels lower than those specified for retrievable liquid "wastes" and for low- or high-concentration PCB spilJs may be necessary on a case-by-case basis where there is a likelihood of direct and repeated human or animal contact; where food chains may be endangered; or where water resources. including swimming pools. may betome contaminated. Regardless of ,the PCB concentration. at least visible traces of spilJed mineral oil and synthetic insulating fluid(s) must be removed from the environment. An 'overviewo{the eIeanùp process is given in Diagram 1 entitled Generic Overview of PCB Cleanup ProceSs; and a detalJed overview o£the 'cleanup process is given in Diagram 2 entitled Cleanup of PCB. PCB-Contaminated. and Non-PCB Spills. Ii I , 1 e e each approved container holding equipment and debris. Equipment and debris are never to be put in the same approved container. A ~Caulion PCB" adhesive label (ML label) must be displayed in access areas to enclosed PCB electrical equipment (500 ppm or greater). except on sidewalk or underground vawts. Access areas include doors. fences. hallways, etc. Firemen must be able to easily read the "Caution PCB" adhesive labels (ML labels) during a fire. The special PCB Hazardous Waste Identification Label is not to be placed on equipment and approved containers containing 50 ppm or greater PCB at the spill or construction site. 7. PCB Electrical Equipment Containment Requirements For a Fire-Related Incident A fire-related incident is, c,iefined as any incident involving PCB equipment which includes the generation of sufficient heat and/or pressure to result in the violent or nonviolent rupture of a PCB transformer and the release of PCBs. Any fire-related incident involving T &D equipment must be treated as a PCB.,...contaminated-re1ated fire until definitely known to be otherwise. When a fire department becomes involved in an equipment fire. the Company shall be responsible for de energizing the equipment so that it is not helping to sustain the fire. The fire department, if necessary, is responsible for putting out the fire after the equipment is deenergized. Contain and control any potential releases of PCBs and incomplete combustion byproducts, especially into water, that are associated with a fire-related incident. Refer to Protection of Personnel and Precaution in Enclosed Spaces for protection of employees during electrical equipment fires. 8. Combustible Materials In PCB Electrical Equipment Locations Combustible materials must not be stored within 20 feet of an enclosure containing PCB electrical equipment. 9. Inspections EPA regulations require periodic visual inspections of known PCB equipment to detect any leaking dielectric fluid. A leak is defined as any quantity of PCB running off or about to run off the equipment. I' Company policy requires all PCB electrical equipment to be retrofilled or removed as soon as possible after discovery. Since less than 1 percent of PG&E's electrical equipment' contains 500 ppm or greater PCB, these types of inspections should occur infrequently. It must be remembered that PCB equipment near food and feed facilities must be inspected weekly until it is removed or at least 90 days after it has been retrofiUed and confirmed to contain less than 500 ppm PCBby laboratory test. On a practical basis. all other inspection intervals will be on a yearly basis., Maintain records of inspections and leaks for all pieces of PCB electrical equipment, except capacitors. on a "PCB Equipment InspeCtion and Maintenance History Repon" (Form 62-4255), Exhibit 1. 10.

When you '~nticipate,pcB c;ontact, wear disposable protective clothing and'>devices which consist of coveralls, plastic overshoes, solvex gloves. a web belt. and face shields. When necessary, tape sleeves 1-3 e e generated when PCBs and otherinsulating fluids are subjected to arcing from electrical faults or fires. Generated vapors are easily detectable by being both pungent smeIling and choking fumes. If it is necessary to enter an enclosure where PCB-contaminated mineral oil or other insu1aüng fluids have vaporized. before the area has been properly ventilated. wear a self-contained or a positive pressure breathing apparatus. Pole-top or padmounted equipment fires involving PCB equipment may require respiratory protecüon, depending on the circumstances. Immediately contact the Electric Distribution Department whenever an equipment fire occurs. I-D. SPILL CLEANUP PROCEDURES The first company employee receiving notice of a spill shall immediately notify the nearest Electric Operaüons Department Dispatcher of the spill. At the first opportunity. the Dispatcher shall send a troub1eman to the spill site and notify an Exempt Supervisor. At the spill site, the troub1eman shall put on appropriate protective clothing and control the spill, barricade the area using the Barricade Tape Adapter Kit or equivalent. and when possible obtain an oil sample from the equipment or source of the spill if the PCB concentration of the insulating fluid is not known. A CLOR-N-OIL 50 PCB Screening Kit can be used to initially determine whether the spill is a non-PCB or PCB-contaminated Spill. The Exempt Supervisor shall arrange for a cleanup crew. direct the cleanup process (which includes notifying the affected property owner(s». and ensure that the necessary records and reporting requirements have been met. AlI spill cleanups must begin within 24 hours of discovery or within 24 hours after the end of an emergency (adverse weather, emergency operaüng conditions. etc.). See Reporting. The Exempt Supervisor shall also notify the Division Gas and Electric Operations Manager, Regional PCB Coordinator, Regional Electric Operations Manager, Materials Department. and other key personnel. After the tailboard briefing and prior to starting any work. the cleanup crew shall put on disposable protective clothing and devices. Spills known or determined to be PCB spills (500 ppm or greater) require full protective clothing or at least disposable overshoes. coveralls. and gloves. Both known PCB-contaminated (assumed or actual) and non-PCB spills, which includes positive or negative test results from the C10r-N-Oil 50 kit. require that at least protective overshoes and gloves be worn. In any case, adequate protective clothing and devices shall be utilized as necessary to avoid contact with insulating fluid by personnel. personal clothing. tools. and equipment. Also, no matter what classification the Clor-N-Oil kit may indicate, equipment oil samples are always to be subsequently taken for analysis by a gas chromatograph. High-concentration PCB spills require a 3-foot lateral buffer around the spill area. In nonrestricted' access areas, all soil (lawn, etc.) with visible traces of oil is required to be excavated to a minimum depth ~ of 1...0 inches or fun her until the PCB con~naûon is reduced to a concentration of no greater than _10 ppmPCB.
