10 April 1996 <br /> AGE-NC Project No. 95-0108 <br /> Page 3 of 5 <br /> 3.0. SCOPE OF WORK <br /> 3.1. SOIL PROBING <br /> AGE proposes to initially advance four soil probings at the site to determine the lateral and vertical <br /> extent of hydrocarbon-impacted soil remaining at the site. Probings will be advanced usincy a <br /> . i <br /> Geoprobe 5400 probing unit equipped with 1.125-inch probing rods. Each probing xvill be advanced <br /> to a depth of-30 feet. One probing will be advanced within the western portion of the former UST <br /> excavation; one probing will be advanced southwest of the former excavation-, and two additional <br /> probing will be advanced in the parking area east of the former UST excavation. The proposed <br /> probing locations are depicted in Figure 2. <br /> Discrete soil samples will be collected at five-foot intervals using a Geoprobe soil sampling assembly <br /> and four pre-cleaned brass sleeves. Upon sample retrieval, the ends of the second brass sleeve will <br /> be covered with Teflon sheets, capped and sealed with tape. Samples .vill be placed in a chilled <br /> container and transported under chain-of-custody procedure to a State-certified laboratory. Elach <br /> sample sleeve will be labeled with the following: boring location. depth, time, date and sampler's <br /> Initials. <br /> 3.2. STOCKPILE SOIL SAMPLING <br /> AGE proposes to collect up to 15 discrete soil samples from hydrocarbon-impacted stockpiled soil <br /> and impacted soil which was backfilled into the UST excavation. Stockpile soil samples 1v;ll be collect <br /> from approximately 2 feet below the surface, soil samples from the backfilled stockpile will be <br /> collected frorn approximately 3 feet below surface grade. Sample will be collected usim, a metric soil <br /> sampler pre-loaded with two 2 by 3-inch brass sleeves. <br /> 3.3 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 probing rods will be cleaned prior to <br /> advancement at each probing location. <br /> 3.4 LABORATORY ANALYSIS <br /> Selected soil 'aid ground water samPLes dill be analyzed fc7r TPH ar1�i BTEc�X in accordance.with <br /> EPA methods 8015n>/5030 and 8020/602, respectively. I.a-beratar�,-reports of both soil and `round <br /> water analyses, testing methods, laboratory quality assurance/quality control (IQA,'QC) reports. and <br />
