Consulting Geologists 7201 Charity Avenue Bakersfield, California 93308 (805) 589-7861 October 14, 1993 Mr. Dan Starkey County of Kern Environmental Health Services Department 2700 M Street, Suite 300 Bakersfield, California' 93301 Dear Mr. Starkey: Enclosed is the site characterization work plan for the steam cleaning facilities on Mr. John Antonino's properties located at 3300 and 3108 Antonino Avenue, Bakersfield, California. If you have any questions, please feel free to call. Yours truly, Duano R. Smith SITE CHARACTERIZATION WORK PLAN VALLEY STEEL CONSTRUCTION SITE BACKGROUND Properties owned by Mr. John Antonino of Valley Steel Construct- ion are located at 3300 and 3108 Antonino Avenue, Bakersfield, California. The properties are situated in the eastern half of Section 23, T.29S., R.27E., M.D.B.& M. (see Figure 1). The area around the properties is .mostly commercial with some open space. Steam cleaning facilities are located an both properties. The steam cleaning facility at 3300 Antonino Avenue is located north of the buil~ting under an attached canopy (see Figure 2). Fluid from the steam cleaning area drains into a buried concrete separation tank and then into a dry well located about 15 feet north of the tank. The tank has only one compartment. Fluid from the separation tank was sampled on May 11, 1993. The diagram of the separation tank is shown on Figure '3. The tank is 2 feet by 2 feet and 4 feet deep. It has concrete sides and a concrete bottom. The drain exits the north side of the tank about 2 feet below the concrete floor. There appears to be a oil/water separator associated with ~this drain. There is a clean out immediately north of the canopy. It is estimated that the dry well is located about 9 feet north of the clean out (see · ~; ~ . ~ .'.' .... ~.,..

The tank is clean at this time and contains only about one-half inch of Water. The steam cleaning facility located~at 3108 Antonino Avenue is located north of the building under an attached canopy (see Figure 4). Fluid from the steam cleaning area drained into a ~ buried concrete separation tank similar to the one at 3300 Antonino Avenue. The fluid then drained into a dry well located about 1.5 feet south of the tank. Fluid from the separation tank was sampled on May 11, 1993. The diagram of the separation tank is similar to the one shown on Figure 3. There does not appear to be an oil/water separator associated with the drain line from the tank to the dry well. The top of the dry well is visible inside a small concrete vault. The casing used in the dry well appears to be 8 inch sewer pipe. The casing was open to a depth of about 13 feet. SITE GEOLOGY The sediments underlying the properties consist of Quaternary alluvial fan deposits. These sediments were deposited from flood stages on the Kern River. They consist mainly of silt, sands, 'and gravels. They are generally moist to slightly moist and poorly consolidated. DUANE R. SMITH AND ASSOCIATES 2 VALLEY STEEL CONSTRUCTION 3108. ANTONINO AVENUE TEST HOLE LOCATION MAP I SMIIH-GUTC:HER AND ASSOCIATES, ocTOBER lg03 According to the Report and General Soil Map, Kern C°unty, California~ published by the Soil Conservation Service of the U.S.D.A., the properties are covered with soils of the Hesperia- Hanford association. These soils consist of well drained moder- ately coarse textured soils developed in granitic alluvium. The surface and subsurface soils are generally classified as massive, sandy loams. According to the 1990 Water Supply Report, published by the Kern County Water Agency, the depth to groundwater beneath the proper- ties was less than 100 feet in January of 1991. No shallow perched groundwater (less than 20 feet below the surface) is known to exist in the general area. PRELIMINARY SITE ASSESSMENT RESULTS The fluid in the separation tank located at 3300 Antonino Avenue was sampled on May 11, 1993. The analytical results are included as Appendix Ao The sample was collected by Mr. David Ritten- house of BC Laboratories. The sample was analyzed for CAM 17 heavy metals, total recover- able petroleum hydrocarbons (EPA Method 418.1), PCB's (EPA Method 8080), volatile organics (EPA Method 8240), and total petroleum hydrocarbons (gas and diesel - Modified EPA Method 8015). DUANE R. SMITH AND ASSOCIATES 3 The CAM 17 heavy metals analyses showed low levels of barium, · copper, lead, and zinc. ~~~eea~a~v~9~ The lead concentration was 8.0 mg/kg. No soluble lead was detected~ in the sample. All other, metal concentrations were none detected based on the practical quantitative limits.' The sample contained total recoverable petroleum hydrocarbons of 6,400 mg/1. No PCB's were detected in the sample. The EPA Method 8240 analyses showed the presence of 1,1,1-trichloroethane at a concentration of 5,000 ~g/1. No benzene was detected in the sample. Total petroleum hydrocarbon concentrations as gasoline and diesel were 70 ~g/1 and 4,200 ~g/1, respectively. The constituent that appears to be of most concern at this location is total recoverable petroleum hydrocarbons. The fluid in the separation tank located at 3108 Antonino Avenue was also sampled on May 11, 1993. The analytical results are included as Appendix B. These samples were also collected by Mr David Rittenhouse of BC Laboratories. Except ·for PCB's (EPA Method 8080), the sample was analyzed for the same constituents as the sample form the separation tank located at 3300 Antonino Avenue. The CAM 17 heavy metal analyses showed low levels of bariUm and zinc. 'N~:~'ner~:'~exceeoeo~:~tne~..-~.~::?~¥~alue. All other metal concen- DUANE R. SMITH AND ASSOCIATES '4 trations were none detected based on the practical quantitative limits. The sample contained total recoverable petroleum hydro- carbons of 180 mg/1. The EPA Method 8240 analyses showed the~ presence of three dichlorobenzenes, tetrachloroethane, and trichloroethane. Total petroleum hydrocarbons as gasoline and diesel were 41,000 ~g/1 and none detected, respectively. The constituent that appears to be of the most concern at this location is total petroleum hydrocarbons as gasoline. SOIL SAMPLING PLAN Three soil borings are proposed to investigate the vertical and lateral extent and the degree of contamination at the property located at 3300 Antonino Avenue. The proposed boring locations are shown on Figure 2. Test Hole No'. 1 will be drilled about 2 feet west of the separation tank. Soil samples will be collected at 2 and 6 feet below the bottom of the tank. This test hole may be drilled deeper depending on possible contamination. It will help delineate the extent of possible contamination under the separation tank. No contamination is expected below this tank. Test Hole No. 2 will be located immediately west of the dry well location. It will help delineate the vertical extent of possible contamination from the dry well. TeS~o~e~NO~will be located ~G~' feet west of Test Hole No. 2. This test hole will help · DUANE R. SMITH AND ASSOCIATES 5 ~ delineate the horizontal extent of possible contamination from the dry well. The borings will be drilled until the maximum vertical extent of contamination is exceeded or to a depth of 50 feet. If contami- nation is found to exceed a depth of 50 feet, further drilling would require the client's authorization. Soil samples will be collected at 5 foot intervals starting at a depth of 10 feet below the surface in Test Holes Nos. 2 and 3. The first soil sample collected from Test Hole No. 1 will be 2 feet below the bottom of the tank. The sample intervals may be modified slightly depending on soil conditions, however, they should not deviate significantly from the intended depths. Approximately 20 soil samples will be collected and field- screened. The 2 and 6 foot soil samples from Test Hole No. 1 and approximately 4 soil samples from Test Hole Nos. 2 and 3 will be submitted to a state certified laboratory ~~~~f.~!~'t~6~I~7~ r~i~70~a~.!~'~ p~t~e~ ?hydr6'~a~b~h'~ ' d's ~ng :-~pA "Meth~.d.-.'.4 1~8 .~. The soil samples will be analyzed by BC Laboratories in Bakers- field. The quality assurance and quality control of the laboratory is available from the laboratory upon request. Chain of custody records documenting sample handling will be included. DUANE R. SMITH AND ASSOCIATES Soil samples will be collected using a split-spoon core sampler driven into the soil utilizing a truck-mounted hollow stem auger rig (Mobile Drill B-53). The split-spoon sampler holds three two and one-half inch diameter by six inch long brass tubes. The core sampler will be driven through the proper interval after the hole is drilled to the sample depth with the hollow stem auger. The sampler will then be removed from the drilling equipment and the brass, tubes removed from the sampler. The ends of one tube from each sample depth will be covered with Teflon seals and PolYethylene caps. The tube will then be labeled and placed in a polyethylene sample bag and the bag sealed and labeled. Each bagged tube will be placed on blue ice and retained in a chilled state for delivery to the laboratory. Another soil sample from each sample depth will be retained for field screening and soil descriptions. Field Screening will consist of a headspace reading for hydrocarbon vapors with an Hnu PID meter. In addition to the headspace readings, hydrocarbon odors, if present, will be noted. The augers will be steam cleaned between test holes. The sam- pling equipment will be scrubbed, washed and thoroughly rinsed between each sample collection. The test holes will be back- DUANE R. SMITH AND ASSOCIATES .7 filled with cement. Contaminated drill cuttings, as identified by field screening, will be placed in DOT drums for future treatment or disposal by the client. Two soil borings are proposed to investigate the degree of contamination at the property located at 3108 Antonino Avenue. The proposed boring locations are shown on Figure 4. Test Hole No. 1 will be hand augered about one foot south of the separation tank through the bottom of the vault around the dry well. It will be slant drilled at an angle of about 15° Soil samples will be collected at approximately 2 and 6 feet below the bottom of the tank. No contamination is expected below the separation tank. Test Hole No. 2 will be hand augered through the middle of the dry well to a depth of approximately 20 feet. Two soil samples will be collected from the test hole. A minimum of 4 soil samples will be collected from the 2 test holes. These will be submitted to a state certified laboratory and aR~'~'6~ ~ total .Petroleum hydrocarbon~ as 'gasoline using'Modified 'EPA' Me'thod 8015. % If the analytical results from either test hole indicate highly contaminated soil, deeper test holes may be needed. These would have to be drilled with a hollow stem fight auger drilling rig. The above approach was proposed due to the ease of hand auguring and limited access to the facility for a large drilling rig. DUANE R. SMITH AND ASSOCIATES Other conditions such as the analytical method, soil sample' collection method, quality control, and decontamination will follow those discussed earlier for the property at 3300 Antonino Avenue. The test holes will not be backfilled with cement unless they are deepened considerably more than projected. SITE SAFETY PLAN The Health and Safety Considerations are included as Appendix C.

Its purpose is to pr°vide established procedures to protect all on-site personnel from direct skin contact, inhalation, or ingestion of potentially hazardous materials that may be encountered at the site. The SSP establishes personnel responsibilities, personal protective equipment, standard decontamination procedures, and emergency action plans. The purpose of this work is to investigate the degree and extent of oil and gasoline contaminated soil. Smith-Gutcher and Associates plans on drilling six soil borings, around two tanks and associated dry wells located on two properties. The borings will be drilled by: Melton Drilling Company 1701 Downing Avenue Bakersfield, California 93306 C-57 license number 508270. The SSP describes means for protecting all on-site personnel from contamination or personal injury while conducting on'site activi- SMITH- GUTCHER AND ASSOCIA INC. l' ties. As described below, we will meet all requirements of the California Department of Health Services. Site Backqround Each property contains one underground tank and a dry well. The tanks were used as separation tanks for steam cleaning facilities. Responsibilities of Key Personnel Ail personnel on-site will have assigned responsibilities. Duane Smith or Tom Gutcher, California registered geologists, will serve as Project Manager, field technician, and site safety officer (SSO). Mr. Smith or Mr. Gutcher will assure that all on-site personnel have a copy of the site safety plan. Personnel will be required to document their full understanding of the SSP before admission to the site. Compliance with the site safety plan will be monitored at all times. A training session will be conducted to assure that all personnel are aware of safe work practices. In the training session, personnel will be made aware of hazards at the site. Mr. Smith or Mr. Gutcher will be responsible for keeping field notes, collecting soil samples, and following chain-of- custody protocol. SMITH- GUTCHER AND ASSOCIATES, INC. 2 On-site employees will take reasonable precautions to avoid unforeseen hazards. After documenting understanding of the SSP, each on-site employee will be responsible for strict adherence'to all points contained herein. Any deviation observed will be reported to the SSO and corrected. On-site employees are held responsible to perform only those tasks for which they believe they are qualified. Provisions of this SSP are mandatory and personnel associated with on-site activities will adhere strictly hereto. Job Hazard Analysis Hazards likely to be encountered on-site include those commonly encountered when operating any mechanical equipment, such as the danger of falling objects or moving machinery. Simple precautions will reduce or eliminate risks associated with operating such equipment. A contractor (Melton Drilling) will be employed to drill and sample six soil borings. Only qualified personnel will have any contact with drilling and sampling equipment. All on-site personnel, including the contractor and his employees, are required to wear hard hats when in close proximity to the drilling equipment. Proper respiratory equipment will be worn if vapor contamination levels on-site exceed action levels as determined using a PID. SMITH- GUTCHER AND ASSOCIATES, INC. 3 Action levels requiring respiratory apparatus will be 10 ppm in the breathing zone. Furthermore, no smoking, open flame, or sparks will be permitted during drilling operations in order to prevent accidental ignition. Risk Assessment Summary Exposure to chemicals anticipated on-site include oil and gasoline constituents. Chemicals in these products can represent a hazard because they are moderately to extremely toxic and most are highly flammable. The Threshold Limits Values (TLV), Short Term Exposure Limits (STEL), and Toxicity levels, all in ppm, are listed below: Gasoline 200 300 Diesel 50 75 Benzene 10 25 4894 Toluene 100 150 5000 Xylene 100 150 4300 Benzene is considered an extreme cancer hazard. SMITH- GUTCHER AND ASSOCIATES, INC. 4 Exposure Monitoring Plan A Photo-Ionization Detector (PID) '.will be used to monitor vaPor concentrations around the sites. Should concentrations exceed TLV levels, protective measures will be taken. Personal Protective Equipment Personnel on-site will have access to respirators with organic vapor cartridges. Replacement cartridges will be available on-site as needed. Hard hats will be worn by all personnel on-site when in proximity of the drilling equipment. Work Zones and Security Measures Access to the area of investigation will be restricted to autho- rized personnel. The Project Manager will be responsible for site security. Decontamination Measures Avoidance of contamination whenever possible is the best method for protection. Common sense dictates that on-site personnel avoid SMITH- GUTCHER AND ASSOCIATES,~ INC. sitting, leaning, or placing equipment on possible contaminated soil. All personnel will be advised to wash their hands, neck, and face with soap and water before taking a break or leaving the site. If respirators are used, they will be washed with soap and water following each day's use. Sampling equipment will be decontaminat- ed before each sample is collected. General Safe Work Practices On-site personnel will be briefed each day in "tailgate" meetings as to the day's goals and equipment to be used. Anticipated contaminants and emergency procedures will be reviewed. The Project Manager will oversee operations and act as the sample coordinator to assure that proper protocol is used at all times in collecting and handling samples. Traininq Requirements The SSO will inform all personnel on site of contaminant proper- ties, health hazard data, risk from exposure, and emergency first SMITH- GUTCHER AND ASSOCIATES, INC. 6 aid. Ail chemicals present will be discussed and the SSO will assure that everyone fully understands site hazards. Medical Surveillance Proqram According to 29 CFR 1910.120 Paragraph (f), employees who wear respirators 30 days or more during one year or who have been exposed to hazardous substances or health hazards above established permissible exposure limits are required to be monitored medically. Record Keepinq Documentation will be kept on personnel exposed to contaminant hazards on the job site according to OSHA regulations. These will include documentation that employees have received training on the SSP, respiratory protection, and all emergency procedures. These will'be reviewed during the pre-site training. Exposure records on each job will be kept for 30 years to meet requirements. Included will be names and social security number of employees, on-the-job logs from entry to exit, first aid adminis- tered, visits on-site by outside persons, and personal air monitoring records.
