17 November 1997 <br /> AGE-NC Project No. 95-0152 <br /> Page 5 of 5 <br /> 6. Boring locations will be marked at least 72 hours in advance for an Underground Service <br /> Alert(USA) check of underground utilities or pipes. <br /> 7. Initially, one soil probe boring will be advanced using a van-mounted Geoprobe 5400 <br /> probing unit (direct push technology: DPT) equipped with 1.25-inch diameter rods. The <br /> probe boring will be advanced to a depth of approximately 40 feet bsg. However, if <br /> hydrocarbon-impacted soil is encountered during sampling, the probe boring may be <br /> advanced to greater depths. The proposed soil probe boring location is depicted on Figure <br /> 2. <br /> 8. Decontaminate all sampling equipment in an alconox solution and rinse twice with water <br /> prior to each sampling run. All probing rods will be cleaned prior to advancement in each <br /> boring. <br /> 9. Soil samples will be collected continuously beginning at a depth of 5 feet bsg. All soil <br /> samples will be collected utilizing a macro-core sampler and acetate sleeves. <br /> 10. Preserve selected soil samples by covering both ends with teflon sheets, capping, and sealing <br /> with tape. <br /> 11. Store the samples under ice and transport the samples in a chilled ice chest to a State certified <br /> laboratory for analysis. <br /> 12. Screen soil sample duplicates for the presence of volatile organics using a photo-ionization <br /> detector(PID)pre-calibrated to isobutylene. <br /> 13. Log sample duplicates in accordance with the Unified Soil Classification System. <br /> 14. Selected soil samples will be analyzed for TPH-g, BTE&X, MTBE and VOCs in accordance <br /> with EPA methods 5030/8015m, 8020 and 8260. Soil samples selected for analysis will be <br /> reviewed with the PHS-EHD prior to analysis by the laboratory. <br /> 4.3. REPORT PREPARATION <br /> Upon completion of probing, sampling and laboratory analysis, a brief report will be prepared <br /> summarizing results of the work performed. The report will include procedures performed and <br /> laboratory findings. The report will be in a format acceptable to the PHS-EHD and will be reviewed <br /> and signed by a California Registered Geologist. <br /> Advanced GeoEnvlronmenlal,Inc. <br />
