SOIL PROBE BORINGS AND SAMPLING <br /> Two (2) soil borings (i.e. B-1, B-2) are proposed near the former fuel dispenser island <br /> area, in a north section of the property; additionally, three (3) soil borings (i.e. B-3, B-4, <br /> B-5) are proposed near the former UST area, in an east section of the property (Figure <br /> 2). <br /> Generally, soil samples will be collected from each boring at 5-foot intervals starting at 5 <br /> feet below surface grade (bsg). If no field evidence of petroleum hydrocarbon impact is <br /> encountered from the soil samples, the borings will be terminated at depths of 10 feet <br /> bsg at (B-1, B-2) and 20 feet bsg (B-3, B-4, B-5). Field personnel may adjust the <br /> frequency and method of sampling in consultation with an AGE Professional Geologist. <br /> Procedures for advancement of soil borings and sampling are presented in Section 3.0. <br /> 2.3. LABORATORY ANALYSIS <br /> Selected soil samples will be analyzed by a California Department of Public Health <br /> (CDPH)-certified laboratory for the following constituents: <br /> • Total Petroleum Hydrocarbons (gasoline, diesel, motor oil) by EPA Method <br /> 8015M; and <br /> • Volatile organic compounds (VOCs) in accordance with EPA Method 8260B. <br /> Laboratory reports for soil sample and groundwater analyses, testing methods, <br /> laboratory quality assurance/quality control (QA/QC) reports, and sample chain-of- <br /> custody documentation will be presented in a report with the findings and <br /> recommendations. <br /> 2.4. REPORT PREPARATION <br /> Upon completion of initial field work and receipt of final laboratory analysis, a report will <br /> be prepared presenting findings of the investigation. The report of findings will include <br /> descriptions of work performed and results of sampling and analysis. Also, conclusions <br /> and applicable recommendations will be included in the report. Reports will be reviewed <br /> and signed by a California Professional Geologist. <br /> 3.0. FIELD PROCEDURES <br /> All field procedures will be overseen by an AGE representative working under the <br /> supervision of a California Professional Geologist.
