➢ Information written on photos, maps and drawings; <br /> ➢ Laboratory data packages; and <br /> > Data qualification packages. <br /> All information pertinent to field sampling operations will be recorded including all field <br /> observations and in situ measurements necessary to explain and reconstruct sampling operations. <br /> The primary repository for the information will be a Dell computer backed up with a field logbook. <br /> Each sample will be identified with a label. Labels will be placed on the containers prior to or at the <br /> time of sampling. Samples requiring refrigeration will be placed in a chest immediately after <br /> collection. A description of sampling locations, sample containers, time of collection, preservations <br /> if any used and various other pertinent facts relative to sample collection and preservation will be <br /> recorded in the field logbook. <br /> Sampleldata collection activities will be documented fully and accurately. Log books will be used <br /> to record mapping locations and specific considerations associated with sample acquisition, <br /> preparation, transportation, receipt by a certified laboratory and analysis to be performed on the <br /> sample. Sample locations will be surveyed so the exact sample locations will be known. In addition, <br /> logbooks will be used to record when and where photographs, temperatures, pressures, etc, are <br /> taken. Field sampling team will have at least one person designated as the Site Supervisor who will <br /> be thoroughly familiar with documentation procedures.The site supervisor will personally perform, <br /> or at least oversee, the completion of documents that accompany the samples. For consistency in <br /> data recording, whenever possible, one person on each field sampling team will record data. Using <br /> one person to record data will permit timely recording of observations, enable more data to be <br /> recorded,and minimize any chances of contaminating field records. <br /> Documentation in logbooks, sample tags, labels, custody seals and other accountable serialized <br /> documents will be completed with permanent reproducible ink. None of these documents will be <br /> destroyed or thrown away, even if the comments are illegible or if inaccuracies are recorded that <br /> must be replaced. The documents will be marked "VOID" and maintained by CGRS. CGRS will <br /> hold all documentation for 5 years subject to the availability of any other authorized person. <br /> Document control means that controlled documents will receive review and concurrence as <br /> appropriate, the distribution of the documents will be recorded and revisions will be made in all <br /> distributed copies. The preparation, issuance and revisions of documents that specify quality <br /> requirements or prescribed activities affecting quality will be controlled to ensure that correct <br /> documents are used. Control will consist of item identification, secure storage and documented <br /> distribution. <br /> 2.0 Measurement/Data Acquisition <br /> 2.1 Sampling Process Design <br /> The pilot trench will be constructed downgradient of the proposed large scale reclamation as shown <br /> on Figure I. The trench will consist of two coal ash cells with a native soil divider as shown on <br /> Figure 2. The ash will be obtained from Public Service Company's Cherokee power plant and will <br /> consist of a combination of Class F silo ash with gypsum and Cherokee 4 Fly ash with sodium. <br /> Monitoring wells will be installed within the ash deposit(s) and compliance points or sentinel wells <br /> will be installed no less than 50 feet downgradient of the trench. It is anticipated that a minimum of <br /> eight wells will be installed up, down and cross gradient to the trench; however, additional wells <br /> Varra Companies <br /> Quality Assurance Protect Plan <br /> Page 6 <br />
