A duplicate sample was also collected and analyzed for TCLP. The samples were collected on Thursday, July 1, 1993, in accordance with the procedures outlined in the Sump Closure Plan prepared by ESC, dated March 18, 1993, and the EPA Region 9 Guidelines for Closure of Shallow Disposal Wells. Mr. Terry Gray of the Kern County Department of Environmental Health Services, was present during the sampling event and approved the location of the samples. Sampling results indicate that no lead was detected in either of the samples collected and analyzed using the TCLP. Sampling results are presented on the enclosed analytical forms from the laboratory for the samples. At this time, ESC formally requests permission to backfill the excavation. The first round of verification sampling results collected at the site on June 2, 1993, indicated that no volatile organic compounds or total petroleum hydrocarbons were present at the bottom of the excavation and that metals were present at levels consistent with background conditions. The results from the supplemental verification samples collected on July 1, 1993, at EPA's request indicate that lead is not present at a level posing a leaching potential. Based on the sampling results and the complete removal of visibly contaminated soil, all residual contamination associated with the sump has been removed. We would appreciate your response to our request to backfill as quickly as possible so that we can complete the site closure activities. Based on discussions with Cynthia Brouwers of your staff, we understand that we have 60 days to submit a closure: report to you from the date that we receive EPA's approval to backfill.

Sampling was in accor- dance with a sump closure plan prepared by Environmental Strategies Corporation. A description of the drainage pathway sampling plan is included in Appendix A of the plan. The location of the drainage pathway was identified by Mr. Terry Grey of the Kern County Environmental Health Services Department. The sample locations were approved by Mr. Grey and the sample collections were witnessed by Mr. Grey. Attachment A shows the soil sample locations relative to the drainage pathway. Soil Sample No. 1 was collected near the wash area just east of a :small shed. Soil Sample No. 2 was collected from just southwest of the sump. Both soil samples were collected from a depth of 3 to 6 inches below the bottom of the asphalt. The soil samples were analyzed by BC Laboratories in Bak- ersfield, California. The analytical results are included Mrs. Cynthia Brouwers Environmental Protection Agency June 25, 1993 Page 2 in Attachment B. The soil samples were analyzed for total petroleum hydrocarbons using Modified EPA 8015 and CAM 17 heavy metals using appropriate methods. No petroleum hydrocarbons were detected in the two soil samples. Both soil samples contained detectable concentrations of heavy metals, but none exceeded the TTLC levels. Barium, lead, and vanadium exceeded the STLC levels in Sample No. 1. Barium and vanadium exceeded the STLC levels in Sample No. 2. None of the heavy metals that exceeded the STLC levels should have soluble concentrations that would exceed the STLC levels since none were more than 10 times their re- spective STLC level. For example, total lead would have to exceed 50 ppm before a soluble concentration could exceed the STLC level of 5.0 ppm. .~ The heavy metal concentrations do not appear to represent a hazard to the environment or to groundwater which was at a depth of about 170 feet below the property in January 1991. No shallow perched groundwater is known to exist in the area. Based on the above data, it appears that no additional soil sampling or remediation is necessary along the drainage pathway.

After reviewing the results, we are concerned about the lead levels in samples taken at the ten foot depth. We request therefore that you take an additional sample from the bottom of the excavation and analyze it for lead content, using the Toxicity Characteristic Leaching Procedure (TCLP). Your analysis will help us determine whether the lead in the soil is likely to leach down to the groundwater. The additional sample should be taken in accordance with the specifications in the Environmental Strategies Corporation Sump Closure Plan dated March 18, 1993, and the EPA Region 9 Guidelines for Closure of &'~allow Disposal Wells. For quality control purposes both original and duplicate samples should be taken and then analyzed at a laboratory certified for TCLP analyses. So that inspectors from thc State, Kern County, or USEPA may be present for the soil sampling, please notify .Cynthia Brouwers of rny staff at (415) 744-1839, Ruben Medina of the Department of Toxic Substances Control at (209) 297-3964, and Terry Gray of the Kern County Department of Environmental Health Services at (805) 861- 3636.

Closure activities were performed at the site on June 2, 1993, and verification samples were collected below the middle of the sump at depths of 0.5, 2.0, 4.0, 6.0, 10.0 and 15 feet. As EPA has requested, each sample was analyzed for volatile organic compounds (VOCs) according to EPA method 8240, CAM-17 metals, and total petroleum hydrocarbons .(TPH) as diesel according to EPA method 3540/8015. The verification sampling results indicate that all contaminants of concern have been excavated and removed from the sump. No VOCs or TPH were detected in the samples collected from depths 10 and 15 feet below the middle of the sump. In these same samples, metals were detected at concentrations well below their respective total threshold limit concentrations (TTLC) and were consistent with typical background soil levels as reported in the U.S. Ecological Survey (USGS) Professional Paper 1270, Element Concentrations in Soils and Other Surficial Materials of the Contiguous United States by Shacklette and Boemgen (1984). A summary of analytical results are presented on Table 1. Analytical forms from the laboratory are presented in Enclosure B. These results are considered final by the laboratory but have not been validated by an ESC Quality Assurance Officer. At this time, ESC formally requests permission to backfill the excavation.

All of the comments provided in your letter of December 31, 1992 to John MacKessy have either been incorporated into tike document or are addressed below. Comment #2 Environmental Strategies Corporation (ESC) has not proposed to collect soil samples along "the route of wash water flow from the wash rack to the sump." No such drainage pattero exists at the site. All rinsing activities were conducted directly over the sump. Comment ESC has included analysis of samples for total petroleum hydrocarbons as diesel in the new work plan. However, we believe that analysis of the samples for volatile organics according to EPA method 8240 or EPA methods 8010 and 8020 is not justified. In Jartuary 1992, a sample of the sludge in the sump was analyzed for volatile organic compounds by EPA method 8010/8020. The only volatile constituents detected in the sludge were benzene, ethyl benzene, toluene, and xylenes. The presence of these constituents is consistent with the past activities conducted at the site. To the best of our knowledge, these activities were limited to steam cleaning of diesel and gas engines and auxiliary oil drilling equipment. If no other volatile constituents were detected in the sludge material, it is unlikely that they will be found at depth.

There is a small sump located about 42 feet north of the Mr. Piston Machine and Parts building. Sludge from this sump was sampled on January 16, 1992. The sump is about 8 feet wide and 10 long. It appears to be about 2.8 feet deep. The thickness of the sludge is about 1.6 feet. The sump is covered by a 2.5 inch steel pipe grate. The bottom of the sump appears to be dirt. A 3 foot concrete apron borders the sump. Asphalt paving extends out from the apron. I was able to collect a sample of the sludge through the grate in the southern portion of the sump (see Attachment A). The sludge was placed in a glass quart jar furnished by BC Laboratory. The jar was completely filled leaving little to no head space. The sample was placed on blue ice and delivered to BC Laboratory for analyses on January 16, 1992. The sample of sludge was analyzed for CAM 17 heavy metals, EPA Method 8010/8020 constituents, total petroleum hydrocarbons (gas and diesel - Modified EPA Method 8015), and oil and grease (EPA Method 413.1). This list of constituents varies from that in 'Mr. Terry Gray February 4, 1992 Page 2 your October 9, 1991 letter to Mr. Mackessy. The analyses was changed after a discussion with you regarding the classification of this site if contaminated. I did not want to have to re- sample the sludge due to some possible future added requirements. Attachment B shows the results of the chemical analyses. The CAM 17 analyses showed high levels of barium, copper, lead, and zinc. All these exceed STLC limits but only lead exceeds the TTLC limit. The sample contained 41,000 ppm oil and grease. The EPA Method 8010/8020 analyses showed typical gasoline constituents. These were benzene, ethyl benzene, toluene, o-xylene, and m-p- xylenes. The benzene concentration was 5 ppm and total xylenes was 57 ppm. Total petroleum hydrocarbon concentrations for gasoline and diesel were 300 ppm and 1,500 ppm, respectively. It appears, based on the above data, that the contaminate of most concern in the sludge is the lead (6,830 ppm). If you have any questions regarding the analysis of the sump sludge, please feel free to call. Yours truly, Duano R.

During the. inspect/on it was noted that there/s a sump which contains rinsate waste that is located on the north side of the shop building in the center of the yard. According to the Kern County Assessor's Office, you are the owner of record of this property and as such are ultimately responsible for any hazardous waste that may be contained in the sump. Characterization is required to determine if the sump waste will be classified as a hazardous waste. In addition, the construction of the sump and terminus of the discharge must be determined. Within thirty (30) days of receipt of this letter, the following must be accomplished: Remove all soil and/or sludge from the sump and place it into appropriately labeled containers. Obtain a representative sample(s) of the sump waste. The sample(s) must be analyzed by a State-Certified Hazardous Waste Laboratory for the following constituents: lead, arsenic, cadmium, and chromium and EPA Method 8240 test for organics. Notify this office forty-eight (48) hours prior to any sampling. When laboratory analyses have been completed, forward a copy of the report 'to this office for review.

Thc site is currently owned by Macke-Vee Company and operated by Mr. Piston Machine and Parts. The closure plan describes the tasks necessary to close a sump located at 4110 Wible Road #D in Bakersfield, California, in accordance with requirements established by thc EPA and the Kern County Department of Environmental Health Services (KCDEHS). It includes a description of site conditions, the scope of work to be performed, the characterization of the materials to be removed, a description of the transportation and waste disposal mechanisms, a health and safety plan, and a list of report submittals. In addition, the sampling procedures and quality assurance and quality control elements are provided in Appendix A. This document has been prepared in accordance with the EPA Region 9 Guidelines for Closure of Shallow Disposal Wells (1992) and guidance provided by the KCDEHS to Mr. John Mackessy in a letter dated Mm'ch 9, 199.2 (Appendix B). Background On August 16, 1990, the KCDEHS inspected the: Mr. Piston facility located at 4110 Wible Road #D in Bakersfield, California, and discovered that a sump was being used to contain run-off waste water from the washing and steam cleaning of engine parts (Figure 1). The sump is located approximately 42 feet north of the Mr. Piston building and is about 8 feet wide, 10 feet long and 2.8 feet deep. The sump is sun'ounded by a 3-foot concrete apron border within an asphalt parking lot and appears to be unlir~l with an earthen botWm (Figure 2). The sides and the bottom of the sump are earthen. The sump was fed s~ctly by overland flow and was not directly connected to any drains, piping, or septic systems. The KCDEHS has classified the sump as a Class V shallow injection well. On October 9, 1991, the KCDEHS sent a violation notice to the respondents requiting them to sample and remove the sludge that, had accumulated in the sump. The respondents took samples from the sludge and submitted the results to the KCDEHS in a letter dated February 4, 1992. A sample of the sludge was analyzed for California Analytical Method (CAM) 17 heavy metals, volatile organic compounds (VOCs), to~al petmlemn hydrocarbons (TPH) as gasoline and diesel, and oil and grease. Sumpling results ate tnv. sented in Appendix C. The only metal detected at a concentration exceeding its total threshold limit concentration (TTLC) of 1000 rog/kg was lead which -1- la %~-I II ESC.

The only VOCs detected in the sample wcrc thozo typically found in pelroleum products. Such constituents included benzell~e ($ rog/kg), ethyl benzene (6 mg/kg), toluene (15 rog/kg), and xylenes (57 rog/kg). The concentration of TPH as gasoline was 300 mg/kg and the concentration of TPH as diesel was 1,500 mg/kg. The level of oil and grease dezected was 41,000 rog/kg. In compliance with the request of the KCDEI-I~ in October 1991, the Respondents immediately ceased all X3 activities associated with the steam cleaning of engine parts and are not allowing any fluids in to the sump through ,' .3~. the placement of a temporary cover (Appendix E). In September 1992, the EPA assumed responsibility as the lead agency for the site and issued an administrative order to the Respondents. The EPA made ~ determination that there is a potential for the contaminants to migrate into underground sources of drinking water and that the elevated concentrations of these contaminants in the drinking water could be ba,ordous to human healt~. The EPA has ordered the Respondents to cease all operations associated with the sump and submit a workplan for its closure. After the workplan has been approved by the EPA, the Respondents must implement the plan and submit a final report within 60 days of the date of approval. Scope of Work This scope of work describes in deudl the events that will take place during the closure of the sump. The EPA will be contacted at least seven days in advance of any site operations relating to closure activities. The sump will be closed in accordance with the terms of the order f~om EPA Region 9 and KCDEHS guidelines. Closure will consist of excavating the sludge that remains in the sump ~d any contaminated soil and properly disposing of them. The sludge is estimated to be 1.6 feet deep and approximately 8 feet by 10 feet in surface are& Before excavating the sludge, all underground utilities will be identified. The 2.5-inch diameter metal pipes forming a grate covering the sump will be removed to gain access. The sludge will be removed with a backhoe and the excavation will proceed until the walls and floor consist of visibly clean soil. It is estimated that approximately 6 to 10 cubic yin'ds of sludge and soil will need to be removed. The sludge will be placed in a properly lined bin and labeled with the coIlection date and site location. The waste will be properly characterized and disposed of (see below). -4- Va~ication anples ~!11~ collected below the; middle of the sump at depths of 0.5, 2.0, 4.0;*a~ 6.0'feet. The samples will be nnalyzed by a sta~ certified laboratory for CAM-17 melals and benzene, Iolnene, ethyl ~e ~_~.L~ and xylene. The samples will provide the technical and analytical ~t~ n_~__~ to determine whether con~atninants ~.~'{-- have migrated beyond the excavation limits. The excav~on pit will be secm'ed and covered while the samples are ~ being analyzed. To determine the need for further remediafion, the verification sampling results will be compared to levels derived from the guidelines in the State Water Resources Con~ol Board (SWRCB) LUFT Field Manual. Verification sampling results will be compared to the following standards to verify that cleanup is complete. Constituent benzene toluene ethyl benzene xylene Cleanup Level (mg/kg) 1 50 50 50 Residual levels of lead in the verification sample; will be compared to a standard of 1,000 mg/kg, its TI'LC. If the results confirm that no further remediafion is neo:ssary, (i.e., all verification samples are less that cleanup standards) the sump will be back-filled and compaCted with clean material. An asphalt cap will be placed directly "~above the compacted ~l material returning the site to its original grade. If the results indicate that there is residual contamination, then fm'ther excavation and ve~ficafion sampling may occur. The extent of posaible further excavation will be based on the verification sampling restfl[ts. If the sump requires extensive excavation or additional remedial action appeam to be required, then the excavat,d pit will be covered with temporary trench plates and an impermeable liner, the remedial options will be evaluatezl, and a new work plan will be prepared. Waste Characterization A composite sample will be collected from the 55-gallon drums and analYzed to determine the appropriate method for disposal of the waste material. The material ~dll be analyzed for the characteristics of b~,ardous waste under the Resource Conservation and Recovery Act (RCRA), as specified in 40 C.F.R. Pan 261 Appendix H and the EPA order. The analytical results will be submitted to the EPA. -5- Transportation and Disposal ~ .. * ~ NoUowing waste characlmizafion, the material ,sill be disposed of at an ~ Californi~ certified disposal facility. The bin containing the sludge will be Nx)perly lined, labeled, and manifested. The wastes, will be transp(nled in accordance with all appropriate U.S. DOT regulations. No waste materials will be allowed to leave thc site until thc load is secured, coveted, and proper stripping papers have been completed and provided to thc drivers. Health and Safety An exclusion zone will be established in the immediate area of excavation and marked by barrier tape. The zone can be adjusted as necessary. A Site Safety Officer (SSO) will be responsible for informing all individuals entering the exclusion zone of the contents of this plan and for ensuring that each person signs the Safety Plan Acknowledgment Form (Appendix F). By signing the Safety Plan Acknowledgement Form, individuals are acknowledging that they have been informed of the presence of specific h~Tards on-site and the policies and procedures required to minimize exposure to potential adverse effects of site haTards. All personnel entering the exclusion zone must have completed uaining requirements for ba-ardous waste site work in accordance with Occupational Safety and Health Administration (OSHA) requirements at 29 CFR 1910.120. The SSO will conduct a site safety kick-off meeting to address the site conditions. All personnel entering the exclusion zone must have completed appropriate mo:lical monitoring requiiv~nents required under 29 CFR 1910.120(0. Previous sampling and analytical data have indicat~xl that the constituents of concern at the site include lead and benzene, chemical hazards associated with these cons0ituents are presented below: 1. Lead (inorganic). · The OSHA time weighted average (TWA.) is 0.05 mg/m3 for air exposure in a 8-hour work day for a40 hour work week · The immed_i~t_e dangerous to life and health, (IDLH) level is 700 mg/m3 through inhalation · The route of exposure could be through inhalation or ingestion -6- 2. Benzene · The NIOSH TWA (10-hour work day) is 0.1 ppm · The IDLH is 3,000 ppm through ittbnlntion · The mute of exposure could be through il~Lhnlnfion or ingestion Because of the potential hnT~rds at the site due to Ihe presence of organic vapors, the air will be sampled regularly with a photoionization detector (PID) to determine, if organic vapor levels rise above background. Level D personal protective equipment (PPE) will initially be used at the site. This will be upgraded to level C PPE if the level of VOCs measured exceeds background by 50 pans per million (gpm) at any time or by 5 ppm for 15 minutes. Upgrade to level C will also occur if the SSO believes that t~he work functions present the opportunity for splashes, immersion in, inhalation of, or contact with ha?ardous eonomtrations of chemicals. Level D PPE will consist of: · Chemical-resistant coveralls or standard work uniforms, as needed. · Steel-toe safety boots. · Gloves as needed. · Safety glasses as needed. · Hard hat. Level C PPE will consist of the above plus: · Chemical-resistant coveralls (uncoated, e.g., Tyvek) · Disposable, chemical-resistant gloves · Air purifying respirator with organic/high-efficiency particulate air-purifying cartridges A confined space is del'reed as a space or work area not designated or intended for normal human occupancy, having limited means of access and poor ventilation, or any structure, including buildings or rooms, which have limited means of egress. There are no confined space entries anticipated for this site. Site personnel will be prepared for an emergency. The following is a list of emergency contacts and directions to the hospital from the site. Fire: 911 Police: 911 Ambulance: 911 -7- Hospital: Address: Telephone: Mercy Hospi 2215 Truxtun Avenue, Bakersfield, CA (209) 632-5000 Directions from site to hospilak Go north on Wible Road and continue to go north as Wible Road becomes Oak $1reet. Turn right on Truxtun Avenue and go 5 blocks down and the hospital will be on the left side of the street (Figure 3). Report Submittals On completion of the closure activities, a report will be submitted to the EPA. The report will include: · a plot plan showing the locations of sampling points, buildings, and adjacent streets · copies of all sludge, soil, and quality control sampling results · copies of manifests or other documentation pertaining to proper disposal of all removed sludge and · a description of the extent of any contamination that may require further investigation or remediation · ff such investigation or remediation appears necessary, recommendations to address the problem from a registered geologist or professional engineer, with sufficient experience in soils and groundwater All reports submitted to EPA that relate to the closure activities, will include the certification given in "Requirements for Contractors." -8" ESC.

Verification soil samples will be collected within the sump using a stainless steel drive shoe sampler containing brass or stainless steel tubes. The sampler will be advanced using a 2.S-inch st~dess steel hand held auger to 0.$, 2.0, 4.0, and 6.0 feet below the sump bottom. A hand held auger will be used to attain the required depth and a drive sampler will be driven into the desired location. The samples collected in the tubes will be capped on both ends with plastic caps and aluminum foil or Teflon, and the caps will be taped to the tube to minimize moisture loss. Each sample container will be labeled and appropriate chain-of-custody and sample identification forms completed. The samples will be placed in a cooler with ice. The samples will be accompanied by a chain-of-custody form. When lxansferring samples, the individuals relinquishing and receiving the samples will sign, date and note the time on the chain-of, custody form. Samples will be packaged properly for shipment and dispatched to the appropriate California State Certified laboratory for analysis. The laboratory will maintain the samples in a cooler at 4° C. The sample custodian at the laboratory will receive and assume custody of the samples. The sample custodian will verify that all samples are present, they are in good condition, they are accompanied by a chain-of- custody form, the sample identification is complete and corresponds to the chain-of-custody form, and that the temperature of the shipping container is appropriate. f The verification samples will be analyzed using EPA methods 8020 for benzene, toluene, ethyl benzene, and xylenes and CAM-17 for metals. A state-certified laboratory will be used and the results provided based on a 24-hour turnaround time. To assure the quality of the sampling results trip bl~k and matrix spike/matrix spike duplicate (MS/MSD) samples will be analyzed. The trip blank is a sample prepared by the laboratory that is transferred with the field samples to ensure, no contamination is introduced in transportation or handling. In the MS/MSD analysis, predetermined quantifies of stock solutions of certain analytes are added to a sample matrix before sample extraction, digestion, and analysis. Samples are split into duplicates, spiked, and analyzed. Percent recoveries are calculated for each of the analytes detected and used to assess analytical accuracy. The relative percent difference between the duplicate samples is calculated and used to assess analytical precision, Duplicate soil samples will not be collected during this sampling event. AH sampling equipment that comes in contact with potentially contaminated soil will be deconmninnted before and after use. In addition, all soil sampling tubes will be cleaned before use.. Sampling'equipment. will be decontaminated by washing with Alconox or tH-sodium pl~tosphate, rinsing with tap water, and rinsing with annly~- free water. AH decontnmination water will be drummed ,~,ith the sludge and disposed of in the same manner. While collecting soil samples, the sampler will wear rubber surgical gloves. The gloves will be replaced with new ones for every sample taken to minimize cross contamination. Each sample tube will be completely filled and undisturbed to minimize volatilization. Waste Characterization Sampling The sample for waste characterization will be collected in two l-quart jars with teflon lined se, pm provided by the disposal facility. The jars will be fdled using a hand trowel decontamination as specified above and labeled. The sample(s) will be analyzed for RCRA hazardous was~g characteristics.

The uip blank is a sample prepiu'ed by thc laboratory that is uansferred with the field samples to ensure no contamination is introduced in transportation or handling. In thc MS/MSD analysis, predetermined quantities of stock solutions of certain analytes are added to a sample matrix before sample exwaction, digestion, and analysis. Samples are split into duplicates, spiked, and analyzed. Percent recoveries are calc,,l~u~cl for each of thc analytes detected and used to assess analytical accuracy. The relative percent difference between the duplicate samples is calculated and used w assess analyficaJ[ precision. Duplicate soil samples will not be collected during this sampling event. All sampling equipment' that comes in contaclt with potentially contaminated soil will be decontaminated before ,and after use. In addition, ,all soil sampling tubes will be cleaned before use. Sampling equipment will be decont,'uninated by washing with Alconox or tri-sodium phosphate, rinsing with tap water, and rinsing with analyte- free water. All deconlamination water will be drummed with the sludge and disposed of in the same manner. While collecting soil samples, the sampler will wear robber surgical gloves. The gloves will be replaced with new ones for every sample taken to minimize cross: contamination. Each sample tube will be completely filled :md undisturbed to minimize volatilization. Waste Characterization Sampling The sample for waste characterization will be collected in two 1-quart jars with ~flon fined septa provided by the disposal facility.

Dear Mr. Mackessy: This letter is an official notice to inform you that the property noted above has been determined ]Dy Kern County Environmental Health Services Department to be the site of a class V shallow injection well. This notice is sent to you because the Kern County Assessor's office records indicate that you are the owner of the property listed above. An initial inspection was conducted on July 19, 1990. During the inspection it was noted that there was a earthen sump located on the north side of the shop building. It was determined that discharge of industrial waste has drained into the sump via runoff from the asphalt lot. Pursuant to Code of Federal R,sgulations 40, (40 CFR), Section 144.12 (a) "no owner or operator shall...operate [an injection well]...in a manner that allows the movement of fluid containing any contaminant into underground sources of drinking water, if the presence of that contaminant may cause a violation of any primary drinking water regulation...or may otherwise adversely affect the health of persons." It also states in Section 144.12 (c) (2) that the Director may "order the injector to take such actions (including, where required, closure of the injection well) as may be necessary to prevent the vio].ation." In 40 CFR, Section 144.12 (d) authorizes the Director to require any action necessary, including well closure, to prevent a Class V well (shallow injection well) from adversely affecting the health of persons. The Kern County Environmental Health Services (KCDEHS) has been designated as the local administrating agency for the above regulations. 2700 "M" STREET, SUITE 300 BAKERSFIELD. CALIFORNL~ 93301 (805) 861-3636 FAX: (805) 861-3429 John Mackessy Page Two March 9, 1992 The Department is responsible for regulating Class V shallow injection wells which are in violation of primary drinking water regulations or may otherwise adversely affect the health of persons, KCDEHS requires closure of the well in such a manner that ensures there will be no movement of fluid containing contaminant into underground sources of drinking water. Therefore, KCDEHS may require, as an element of proper well closure, cleanup in and around the class V well. To expedite KCDEHS approval, all well closure plans must, at a minimum, address the following elements and describe in detail how the compliance will be accomplished: 1. Describe an acceptable alternative for disposal of waste fluids in the future. 2. Identify the locations of all drains, drain lines, dry wells, and cesspools or septic systems at the facility. 3. Contact KCDEHS at least seven (7) days in advance of any site operations relating to the workplan activities. 4. The contaminated soil must be excavated, and all visibly contaminated soil must be disposed of in an approved manner. Soil samples must be retrieved at depths of two (2) and six (6) feet below tlhe sludge. The samples must be analyzed by a STATE CERTIFIED LABORATORY for the following contaminants. A. Barium, copper, lead and zinc. B. Benzene, ethyl benzene, toluene, and total xylenes C. 1,1-Dichloroethane, and tetrachloroethane (PCE). The area must be backfilled using clean fill after the removal of all contaminated soil. 5. This workplan does not constitute a remediation plan. The KCDEHS must review alll sampling results to determine if remediation is necessary. In the event analytical results of the soil samples indicate the presence of contamination, the workplan must address remediation alternatives and be approved by KCDEHS. 6. Work must commence within 30 days of receipt of this notice.

PA) Adminislrative Order Docket No. AO-CA92~01 (Order) section 15, dated September 30, 1992, issued o to Macke-Vee Company and Mr. Piston (the Respondents). The site is currently owned by Macke-Vee Company and operated by Mr. Piston Machine and Parts. The closure plan 'describes the tasks necessary to close a sump located at 4110 Wible Road #D in Bakersfield, California, in accordance with requirements established by the EPA and the Kern County Department of Environmental Health Services (KCDEHS). It includes a description of site conditions, the scope of work to be performed, the characterization of the materials to be removed, a description of the transportation and waste disposal mechanisms, a health and safety plan, and a list of report submittals. In addition, the sampling procedures and quality assurance and quality control elements are provid~ed in Appendix A. This document has been prepared in accordance with the EPA Region 9 Guidelines for Closure of Shallow Disposal Wells (1992) and guidance provided by the KCDEHS to Mr. John MacKessy in a letter dated March 9, 1992 (Appendix B). Background On August 16, 1990, the KCDEHS inspected the Mr. Piston facility located at 4110 Wible Road #D in Bakersfield, California, and discovered that a sump was being used to contain nm-off waste water from the washing and steam cleaning of engine parts (Figure 1). The sump is located approximately 42 feet north of the Mr. Piston building and is about 8 feet wide, 10 feet long and 2.8 feet deep. The sump is surrounded by a 3-foot concrete apron border within an asphalt parking lot and appears to be unlined with an earthen bottom (Figure 2). The sides and the bottom of the sump are earthen. The sump was fed strictly by overland flow and was not directly connected to any drains, piping, or septic systems. The KCDEHS has classified the sump as a Class V shallow injection well. On October 9, 1991, the KCDEHS sent a violation notice to the respondents requiring them to sample and remove the sludge that had accumulated in the sump. The respondents took samples from the sludge and submitted the results to the KCDEHS in a letter dated February 4, 1992. A sample of the sludge was analyzed for California Analytical Method (CAM) 17 heavy metals, volatile organic compounds.(VOCs), total peltoleum hydrocarbons (TPH) as gasoline and diesel, and oil and grease.

The only vocs detected in the sample Were those typicaliy found in pela'oleum products. Such constituents included benzene (5 mg/kg), ethyl benzene (6 mg/kg), toluene (15 mg/kg), and xylenes (57 rog/kg). The concenuation of TPH as gasotine was 300 mg/kg and the concentration of TPH as diesel was 1,500 rog/kg. The level of oil and grease deto:ted was 41,000 mg/kg. In compliance with the request of the KCDEHS in October 1991, the Respondents immediately ceased all activities associated with the steam cleaning of engine pa~ and are not allowing any fluids in to the sump through the placement of a temporary cover (Appendix E). In September 1992, the EPA assumed responsibility as the lead agency for the site and issued an achninistrative order to the Respondents. The EPA made a determination that there is a potential for the contaminants to migrate into underground sources of drinking water and that the elevated concentrations of these contaminants in the drinking water could be baTardous to human health. The EPA has ordered the Respondents to cease all operations associated with the sump and submit a workpl~aa for its closure. After the workplan has been approved by the EPA, the Respondents must implement the plan ~md submit a final report within 60 days of the date of approval. Scope of Work This scope of work describes in detail the events that will take place during the closure of the sump. The EPA, the Department of Toxic Substances Conu'ol (DTSC), and KCDEHS will be contacted at least seven days in advance of any site operations relating to closure activitie.~;. The sump will be closed in accordance with the terms of the order from EPA Region 9 and KCDEHS guidelines. Closure will consist of excavating the sludge that remains in the sump and any contaminated soil and properly disposing of them. The sludge is estimated to be 1.6 feet deep and approximately 8 feet by 10 feet in surface area. Before excavating the sludge, all underground utilities will be identified. The 2.5-inch diameter metal pipes forming a grate covering the sump will be removed to gain access. The sludge will be removed with a backhoe and the excavation will proceed until the walls and floor consist of visibly clean soil. It is estimated that approximately 6 to 10 cubic yards of sludge and soil will need to be removed. -4. The sludge will be placed in a properly lined bin and labeled .wilh. thc, collection date waste will be properly characterized and disposed of (see below). Verification samples will be collected below the middle of the sump at depths of 0.5, 2.0,. 4~0, and 6.0 feet. If thc soil is visibly contaminated at the 6 foot depth, addi~onal samples will be takon every 5 feet to a depth 5 feet below the last suspected contamination. The samples will be analyzed by a state certified laboratory for CAM-17 metals, benzene, toluene, ethylbenzene, and xylene (BTEX), and TPH as diesel. Samples will be collected in accordance with the sampling and analysis plan presented in Appendix A. The samples will provide the technical and analytical data necessary to determine whether contaminants have migrated beyond the excavation limits. The excavation pit will be secured and covered while the samples are being analyzed. Verification sampling results will be provided to EPA who, with the assistance of the DTSC and the KCDEHS, will evaluate the analytical results and determine if further action is necessary. If the results confn'm that no further remediation is necessary, (i.e., all verification samples are less that cleanup standards) the sump will be backfilled and compacted with clean material. An asphalt cap will be placed directly above the compacted fill material returning the site to its original grade, ff the results indicate that there is residual contamination, then further excavation and verification sampling may occur. The extent of possible further excavation will be based on the verification sampling results. If the sump requires extensive excavation or additional remedial action appears to be required, then the excavated pit will be covered with teml:orary trench plates and an impermeable liner, the rem~i_a_l options will be evaluated, and a new work plan will be prepared. Waste Characterization A composite sample will be collected from the 55-gallon drums and analyzed to detexmine the appropriate method for disposal of the waste material. The material will be analyzed for the characteristics of hazardous waste under the Resource Conservation and Recovery Act CRCI~k), as specified in 40 C.F.tL Part 261 Appendix H and the EPA order. The analytical results will be submitted to the: EPA. Transportation and Disposal Following waste characteriTmion, the material will be disposed of at an appropriate California certified disposal facility. The bin containing thc sludge will be properly lined, labeled, and manifested. The wastes will be -5" wansponed in accordance wilh all appropriate U.S. DOT ~;gn,lations. No war,~ malefials..will.be allowed lo leavethe site until the load is secured, covered, and proper shipping papers have been completed and provided m Ohe drivers. Health and Safety An exclusion zone will be established in the imme. diate area of excavation and mmked by ban'ier tape. The zone can be adjusted as necessary. A Site Safety Officer (SSO) will be responsible for informing all individuals entering the exclusion zone of the contents of this plan and for ensuring that each person signs the Safety Plan Acknowledgment Form (Appendix F). By signing the S,'ffety PLan Acknowledgement Form, individuals are acknowledging that they have been informed of the presence of specific hazards on-site and the policies and procedures required to minimize exposure to potential adverse effects of site ha?~ds. All personnel entering the exclusion zone must I~tve completed training requirements for haTardous waste site work in accordance with Occupational Safety and E[ealth Administration (OSHA) requirements at 29 CFR 1910.120. The SSO will conduct a site safety kick-off mee~!ing to addres'~ the site conditions. All personnel entering the exclusion zone must have completed appropriate medical monitoring requirements required under 29 CFR 1910.120(0. Previous sampling and analytical dam have indicated that the constituents of concern at the site include lead and benzene, chemical hazards associated with these constituents are presented below: 1. Lead (inorganic). · The OSHA time weighted average (TWA) is 0.05 mg/m3 for air exposure in a 8-hour work day for a 40 hour work week · The immediate dangerous to life and health, (IDLH) level is 700 mg/m~ through inhalation · The route of exposure could be through inhalation or ingestion 2. Benzene The NIOSH TWA (10-hour work day) is 0.1 ppm · The IDLH is 3,000 ppm through inhalation · The route of exposure could be through inhalation or ingestion Because of the potential ha?ards at the site due to the presence of organic vapors, the air will be sampled regularly with a photoionization detector (PID) to determine if organic vapor levels rise above background. Level .6.¸ level of VOCs measured exceeds background by 50 parts per million (ppm) at anytime or b~,~'~'~fO~IS '~'~minutes. ''~ Upgrade to level C will also occur if the $S0 believes ~t the work functions present the opportunity for splashes, immersion in, inhnlotion of, or contact with baT~rclous concentrations of chemicals. Level D PPE will consist of: · Chemical-resistant coveralls or standard work uniforms, as needed. · Steel-toe ~afety boots. · Gloves as needed. · Safety glasses as needed. · Hard hat. Level C PPE will consist of the above plus: · Chemical-resistant coveralls (uncoated, e.g., Tyvek) · Disposable, chemical-resistant gloves · Air purifying respirator with organic/high-efficiency particu!ste air-purifying cartridges A confined space is defined as a space or wo:rk area not designated or intended for normal human occupancy, having limited means of access and poor ventilation, or any structure, including buildings or rooms, which have limited means of egress. There are no confined space entries anticipated for this site. Site personnel will be prepared for an emergency. directions to the hospital from the site.

CASE NARRATIVE CLIENT NAME: Environmental Strategies Corporation PROJECT NAME: Bakersfield PROJECT #: CA117204 DATE: June 11, 1993 LAB REPORT #: 3F13601 The samples in this report have been analyzed by SW-846 method 8240 for Volatile Organics, Modified 8015 for 'l"otal Extractable Hydrocarbons and by 6010 and 7471 for the CAM 17 metals. For method 8420, samples 3F13601 (S-0.5-Sump), 3F13602 (S-2-Sump), and 3F13603 (S-4-Sump) were extracted on June 8, 1993. The samples showed Iow surrogate recovery and were reextracted in accordance with method 8240. The reextraction also demonstrated Iow surrogate recovery, therefore, the values reported for these samples should be considered estimated. The extraction blank for the Total Extractable Hydrocarbons (Modred 8015) had contamination believed to be from viial septa. The blank contamination was not subtracted from the sample results because it was either negligible with respect to the sample or not present as evidence by the pattern of the chromatograms. The method blank for copper and zinc also showed contamination, which was also not blank subtracted from the sample results. This contamination was negligible with respect to the sample results.

The soil sampling and analysis in the drainage way is not part of the agreement between Mr. John Mackessy and the party that constructed the sump. Mr. Mackessy requested that I collect and have analyzed the two soil samples from the drainage way. The soil samples will be sampled and analyzed in accordance with the sump closure plan prepared by Environmental Strategies Corpora- tion. BC Laboratories will analyze the soil samples as per the work plan. Soil sample collection will be witnessed by personnel form the Kern County Environmental Health Services Department.

Before approval of the work plan can be granted, comments 2, 3, and 4 from the December 31, 1992, letter must also be addressed. These comments reflect the requirements of the U. S. Environmental Protection Agency (USEPA), the California Department of Toxic Substances Control (DTSC), and the Kern County Department of Environmental Health Services (KCDEHS). Comment No. from December 31, 1992 lette_r 2) During inspections of the site, both KCDEHS and DTSC persormel noted that Mr. Piston employees were washing equipment at a washrack located at the rear of the building and that the washwater was then flowing over the ground to the sump. Therefore we believe that it is necessary to sample the soil under this drainage route to determine if any contamination exists. The work plan must describe how and where such samples will be taken. 3) Appendix A: Sampling and Analysis PI, re~Quality Assurance Control Plan of the work plan states that trip blank and matrix spike/matrix spike duplicate samples will be analyzed. As described on page 20 of the EPA Region 9 Guidelines for Closure of Shallow Disposal Wells, the work plan must state that at least one replicate blank will be analyzed. Printed on Recycled Paper 4) COuld be present at the site because businesses such as Mr. Piston and previous tenants at the site have COmmonly used solvents COnm~nlng VOCs to b. leanparts and equipment. Regarding the earlier samples mentioned in the letter from' Environmental Strategies Corporation, dated January 18, 1993, we don't have any information about how those samples were taken, so we don't COnsider the samples to be reliable indicators of the presence or absence of any COntaminants at the site. Therefore the work plan :must state that the soil samples will be analyzed for VOCs .in accordance with either EPA method 8240 or EPA methods 8olo/8o2o. As described on page 9 of the EP,4 Region 9 Guidelines for Closure of Shallow Disposal Wells, the well casing must be removed prior to soil sampling. Therefore the work plan' must describe how the concrete apron and any COncrete sidewalls will be removed and properly disposed of. As stated in paragraph 19 of the Adn~tistrative Order, you have ten days to submit a new work plan addressing these comments. Once the work plan is approved, you will have sixty days to implement it and submit a final report. If you have any questions, please don't hesitate to contact Cynthia Brouwers of my staff at (415) 744-1839.
