In general, the analytical results revealed varying concentrations of oil and grease at 2 feet and 6 feet beneath the tank. 2.3 Problem Statement: The area of concern regarding the project site is the extent of contaminated soil in the area of the underground storage tank. In a letter from Mr. Bill Scheide of the Kern County Health Department, Environmental Health Division, Mr. Scheide indicates that his department requests a site characterization study to determine the extent of this contamination. Fresno Modesto Visalia Bakersfield I~aacs and Bailey September 1, 1988 Page 5 3.0 PURPOSE AND S¢0PE.O[INVESTIGATION The objectives of the proposed engineering investigation are presented-as follows: Determine the existence and concentration of selected. constituents in the soils in the area of the under- ground storage tank. Evaluate the findings to determine if adequate infor- mation has been developed by this investigation to define the general vertical and horizontal extent of contaminate migration in the area of the underground storage tank..This is a preliminary investigation. After the findings of this investigation have been reviewed, further investigation may be necessary to develope additional information regarding the extent of contaminate migration and concentrations in the soil. If adequate information has been developed by this investigation, address clean-up alternatives and dis- cuss possible mitigation measures which could be undertaken. The general scope of this investigation, which is deemed necessary to achieve the above referenced objectives is as follows: 'Using a drilling rig, d~ill down to an'anticipated maximum depth of 25 feet below the surface. Obtain undisturbed soil samples at intervals of 5 feet starting at a depth of 5 or 10 feet and continuing to an anticipated maximum depth of 25 feet. Analyze selected soil samples in the laboratory for the presence and concentration of seleCted constituents. Evaluate the data produced during the investigation to determine, if possible, the general extent of the constituent migration in the soil. Fresno Modesto Visalia Bakersfield Isaacs and Bailey September 1, 1988 Page 6 4.0 TECHN!.CAL APPROACH This section presents the details of our proposed field investigation and laboratory testing program. 4.1 Sampling Plan: In order to develope information to aid in determining the general vertical and horizontal extent of contaminant migration in the soils near the underground storage tank, would be drilled tQ/~aa~,anticpated maxxmum~%d~~o,f~-~~at the locations shown on Drawing No. 2. However, should discoloration or petroleum odor be present in the samples-at a depth of 25 feet then the bor.ing would~be,cOhtinued until presen.~' in two consecutive sample intervals..~'in the boring. The depth and locations of the borings were selected based on the information obtained from Mr. Cecil Bailey and Mr. Chuck Oliver regarding the previous investigations performed and the location of the underground tank. All field work associated with the collection of soil samples from the project site would be supervised by an engineer from our firm. The borings would be terminated at an anticipated maximum depth of 25 feet or when groundwater is reached. In addition, the borings would be terminated if auger refusal is encountered. The exploratory soil boreholes will be drilled at the proposed locations using a truck mounted drilling rig equipped with hollow stem continuous flight augers. The hollow stem augers will be used to ensure sample integrity by preventing soils from caving to the bottom of the borehole during drilling. Prior to drilling each borehole, the Fresno Modesto Visalia Bakersfield IsaaCs and Bailey. September 1, 1988 Page 7 hollow stem augers will be steam cleaned to prevent cross-contamination between boreholes. ~U~until completion of the site characterization. 4.2 Soil Sampling: Soil samples will be obtained from each boring at intervals of 5 feet starting at a depth of 5 or 10 feet below existing site grade. Once the required sampling depth has been reached, a representative soil sample will be obtained using a California Modified Sampler equipped with pre-cleaned brass tube liners and sample retainers. Th~ sampler will be driven or pushed approximately 18 inches into the undisturbed soil ahead of the auger. Selected samples will be collected and submitted to the laboratory for analysis of appropriate constituents. Prior to being used for sampling, the brass tubes and samplers will be cleaned with a steam cleaner or a TSP solution to preve:nt introduction of any contaminants into the soil samples and to prevent cross-contamination between samples. The sample containers to be used consist of one and one-half inch by four inch brass tubes. The brass tubes, pre-cleaned at the laboratory prior to use, are placed in the sampler and pushed or driven as described above to collect the soil samples. Upon removal from the borehole, the ends of each tube containing the sample...will- be] inspected visually to identify the lithology penetrated described on the borehole log using the Unified Classification System~, and any discoloration or ordor from the sample would be noted. The ends of ~esno Modesto Visalia Bakersfield Isaacs and Bailey September 1, 1988 Page 8 the samples would then be covered with aluminum foil and plastic caps. The caps will be taped to the tube to provide an airtight seal. Each sample will be appropriately marked on site to show the date, job number, borehole number and sample depth. Following marking of the samples, they will be sealed in plastic bags (to further protect from melt water), placed on ice in an ice chest and then shipped as such to the laboratory. Ail samples received at the laboratory may not be analyzed in the laboratory. We have anticipated for our estimated budget the laboratory analysis of three samples from each boring. 4.3 Analytical Procedures: The analytical procedures for this investigation are designed to determine the presence or absence of contaminants in the soil in the vicinity of the project. The details of our analytical procedures are presented in the following sections. 4.3.1 Soil Analysis: Each soil sample subjected to laboratory analysis will be .analyzed for the presence and concentrations of the following constituents: Type of An~lyis Method Oil and Grease EPA SW-846: M~hod~.2~ Total Halogenated Hydrocarbons bPA SW-846: Me~hod~i~U Total Lead EPA SW-846: MethOd~-~7'~2~ SW-846: Test Method fgr Evaluation of Solid W~ste, U.S. EPA, Office of Solid Waste and Emergency aesponse, July, 1982, 2nd Edition. Fresno Modesto Visalia Bakersfield Isaacs and Bailey September 1,,.1988 Page 9 These substances are those listed for the analysis of soil samples for the detection of waste oil constituents in the Kern County Health Department Handbook #UT 30 "Requirements for Permanent Closure of Underground ~azardous Substance Storage Tanks". 4.4 Ouali~y Assurance Plan: This section describes the field and analytical procedures to be followed throughout the investigation. 4.4.1 General Sample Collection an~ }{andlin.g procedures: Proper collection and handling are essential to ensure the quality of a sample. Each sample will be collected in a suitable container, preserved correctly for the intended analyses and stored for analysis for no longer than the maximum allowable holding time. Details on the sample collection and handling procedures used on this project can be found in the sections for soil sampling. 4.4.2 Sampl~ Identification add Chain-of-Custody Procedures: Sample identification and chain-of-custody procedures ensure sample integrity and documented sample possession from the time of collection to its ultimate disposal. Each sample container submitted for analysis will have a label affixed to identify the job number, sampler, date and time of sample collection and sample number unique to the sample. This information, in addition to a description of the sample, sampling methodology, names of on-site personnel and any other pertinent field observations will be recorded. All sample analysis will be performed by our laboratory. A chain-of-custody form will be used to record possession of the sample from time of collection to its Fresno Mo. desto Visalia Bakersfield Isaacs and Bailey September 1, 1988 Page 10 arrival at the laboratory. When the samples are shipped, the person in custody of them relinquishes the samples by signing the chain-of-custody form and noting the time. The sample control officer at the laboratory verifies sample integrity and confirms that it was collected in the proper containers, preserved correctly and that there is an adequate volume for analysis. If these conditions are met, the sample will be assigned a unique log number for identification throughout analysis and reporting. The log number will be recorded on the chain-of-custody form and in the legally required log book maintained at the laboratory. The sample description, date received, client's name and any other relevant information will also be recorded. 4.4.3 Analytical Ouality Assurance: In Addition to routine calibration of the analytical instruments with standards and blanks, the analyst is required to run duplicates and spikes on ten percent of the analyses to ensure an added measure of precision and accuracy. Accuracy is also verified through the following: 1. U.S. Environmental Protection Agency (EPA) and state certification results. 2. Participation in inter-laboratory or "round-robin" program. "Blind" samples are submitted by the laboratory quality assurance officer on a weekly basis. These are prepared from the National Bureau of Standards EPA reference standards. Fresno Modesto Visalia Bakersfield Isaacs and Bailey September 1, 1988 Page 11 4. Verification of results with an alternative method. For example, calcium may be determined by atomic absorption, ion chromatography or titrlmetric methods. Volatile organics may be determined through either purge and trap or liquid-liquid extraction methods. 4.4.4 Miscellaneous Checks of Accuracy: Where trace analysis is involved, purity of the solvents, reagents and gases employed has been of great concern. Our laboratory maintains a service contract on all major instrumentation: gas chromatographs, atomic absorption, ion chromatography and total organic carbon analyzers are serviced and maintained regularly. The above outlined quality assurance program has been more than sufficient for most projects. Additional quality assurance, such as spikes and duplicates on all anaylses, can be provided if requested. 4.5 Site Safety Plan: This plan addresses safety provisions employed during the investigative field work in the vicinity of the site. The objective of the plan is to describe procedures and actions to protect the worker and uninvolved parties from direct skin contact, inhalation, or ingestion of potentially hazardous materials that may be encountered at the site. The plan describes: 1) the nature of potential materials, 2) personnel responsibilities, 3) respiratory protection, 4) clean-up/decontamination procedures, and 5) emergency procedures. 4.5.1 The Nature of the Potential Materials: The materials that may be encounter during drilling at the site include waste oil Fresno Modesto Visalia Bakersfield Isaacs and Bailey September 1, 1988 Page 12 constituents in soils. The provisions of this safety plan are designed to protect workers from the above described constituents. 4.5.2 Personnel Responsibilities: Key personnel directly involved in the investigation will be responsible for monitoring the execution of safe work practices. These personnel will be responsible for knowing the provisions of the plan, communicating plan requirements to workers under their supervision and to site visitors and for enforcing the plan. 4.5.3. Respiratory Protection: }{alf-face respirators equipped with an organic vapor cartridge are issued to all field Personnel for their use when necessary during field opertaions. The field engineer will be responsible for determining the use of these respirators o 4.5.4 Personnel Protection: The designated personnel protective equipment has been selected to prevent field personnel from exposure to diesel fuel products that may be present at the site. To prevent direct skin contact, the following protective clothing will be worn as appropriate while working at the site. 1o Hard hat with optional face shield. 2o Tyvek coveralls. 3o Butyl rubber and disposable vinyl gloves. 4° Neoprene boots, steel toe. 5° Goggles or safety glasses (if optional face shield not used on the hard hat). Fresno Modesto Visalia Bakersfield ~Isaacs and Bailey September 1, 1988 Page 13 The type of gloves will be determined by the type of work being performed. Drilling personnel will wear butyl rubber gloves when necessary due to their long duration contact with the subsurface materials. Twining sampling pe~sonnel will wear disposable vinyl gloves when handling any sample. When required, personnel protective equipment shall be put on before entering the immediate work area. The sleeves of the coveralls will be outside of the cuffs of the gloves to facilitate removal of clothing with the least potential contamination of personnel. If at any time protective clothing (coveralls, boots or gloves) becomes torn, wet or excessively soiled, ~.t will be replaced immediately. No eating, drinking or smc, king will be allowed in the vicinity of the drilling operations. Twining Laboratories will designate a separate area on-site for eating and drinking. Smoking will not be allowed in the vicinity of the site, except in designated areas. No contact lenses will be worn by field personnel. 4.5.5 Clean-Up/Decontamination Procedures: Property clean-up/decontamination procedures are essential to prevent transporting potentially contaminated material from the site and to protect the health of field personnel. At the end of the workday, the following procedures will be used as appropriate to allow for the safe removal and decontamination of protective equipment. Fresno Modesto. Visalia Bakersfield Isaacs and Bailey September. l, 1988 Page 14 1. Boots and gloves will be washed with soap and tap water, then rinsed before removal. 2. Boots and coveralls will be removed and may be placed in a designated drum for proper disposal. 3. Gloves will then be removed and may also be placed in the designated drum; hands will be washed with soap and water. 4.5.6 Emergency Procedures: Symptoms of direct exposure to significant concentrations of gasoline and/or diesel fuel products include: irritation of the eyes, nose and skin; vomiting; headache, dizziness, light-headedness; ~Lack of coordination; nausea and unconsciousness. If any of these symptoms develop, operations will be stopped and medical attention obtained as necessary. If any of these symptoms occur, first aid procedures for direct exposure to the on-site materials are: 1. Skin: Remove contaminated clothing immediately. Flush affected area immediately with water, then wash with soap and water. Eyes: Hold the eyelid open and flush with water. Lungs: Move to freah air immediately; give arti- ficial respiration as necessary.
