'`r NEW, <br /> 1 December 1995 <br /> AGE-NC Project No. 95-0106 <br /> Page 3 of 5 <br /> Grab ground water samples will be collected from at least three of the probings. Ground water <br /> samples will be collected using a Geoprobe water sampling assembly. After collection, samples will <br /> be stored in a chilled container and transported to a State-certified laboratory. <br /> 3.2. EQUIPMENT DECONTAMINATION <br /> All sampling tools and brass sleeves used for sample collection will be thoroughly rinsed with clean <br /> water after washing with a solution of Alconox. All Geoprobe rods are cleaned prior to advancement <br /> in each probing location. <br /> 3.3. LABORATORY ANALYSIS <br /> Selected soil and ground water samples will be analyzed for TPH-g and BTE&X in accordance with <br /> EPA methods 8015/5030 and 8020/602, respectively. Laboratory reports of both soil and ground <br /> water analyses, testing methods, laboratory quality assurance/quality control (QA/QC) reports, and <br /> sample chain of custody documentation will be presented in a report with the findings and <br /> recommendations. <br /> 3.4. BACKFILLING OF EXCAVATION <br /> If the subsurface investigation of the site indicates that hydrocarbon impacted soil is laterally <br /> extensive, the excavation will be backfilled using the stockpiled soil. If appropriate, crushed rock will <br /> be placed into the excavation and stockpiled soil will be compacted on top of the crushed rock. <br /> If the subsurface investigation of the site indicates that hydrocarbon-impacted soil is limited to the <br /> immediate vicinity of the UST area, the remaining excavated soil will be excavated and disposed at <br /> a licensed landfill facility(Note: excavation procedures were included in the initial work plan prepared <br /> for the site). <br /> 4.0. PROCEDURES <br /> 4.1. COLLECTION OF SOIL AND GROUND WATER SAMPLES <br /> For the collection of soil and ground water samples, the following procedures will be performed: <br /> 1. Prepare a site health and safety plan in accordance with Occupational Safety and Health <br /> Guidance Manual for Hazardous Waste Site Activities (Prepared by National Institute for <br />
