Remediation of Soils and Dry Sediments at RVAAP 08-11 (LLs 1-4)<br />

facility requirements ultimately dictated <strong>the</strong> sample frequency and analyses per<strong>for</strong>med <strong>for</strong> <strong>the</strong><br />
soil stockpiles. Waste samples were collected at a minimum of one sample per stockpile which<br />
translated into a frequency of greater than one sample per 700 cubic yards of material excavated.<br />
In all, a total of 13 waste characterization samples were analyzed <strong>for</strong> <strong>the</strong> following parameters:<br />
• Toxicity Characteristic Leaching Procedure (TCLP) analysis <strong>for</strong> in<strong>org</strong>anics, mercury,<br />
pesticides, herbicides, and SVOCs<br />
• PCBs<br />
• Nitroaromatics and nitramines<br />
• RCRA characteristics (reactive cyanide and sulfides, pH, and ignitability)<br />
Analytical results <strong>for</strong> all <strong>the</strong> waste characterization samples collected from <strong>the</strong> excavated soil<br />
stockpiles did not identify any of <strong>the</strong> soils to be hazardous. No local disposal facilities were<br />
permitted to accept soils with known PCB concentrations greater than 50 mg/kg; <strong>the</strong>re<strong>for</strong>e, in<br />
order to be conservative, <strong>the</strong> soil stockpiles with <strong>the</strong> known concentrations of PCBs greater than<br />
40 mg/kg were shipped to an out-of-state facility that was permitted to accept <strong>the</strong> material.<br />
A summary of waste characterization analytical results <strong>for</strong> <strong>the</strong> soil stockpiles are presented in <strong>the</strong><br />
data tables (Table B-5) in Appendix B. The laboratory reports and associated data evaluation<br />
reports <strong>for</strong> waste characterization samples are in Appendix H included as an electronic<br />
attachment to this RACR.<br />
4.1.3 Load-Out to <strong>the</strong> Disposal Facility<br />
Stockpiled soils and dry sediments were loaded into trucks in designated areas only with<br />
adequate spill control measures, including equipment to catch and contain spillage, and<br />
equipment necessary to recover spillage and clean <strong>the</strong> area. Dust control measures were<br />
implemented as necessary during loading. Disposable sheeting was placed on <strong>the</strong> ground around<br />
trucks to catch any incidental spillage during loading. Be<strong>for</strong>e loading, trucks were inspected and<br />
surveyed <strong>for</strong> damage and residual contamination by Shaw personnel.<br />
Materials were loaded into each transport vehicle in a uni<strong>for</strong>m manner and distributed over <strong>the</strong><br />
full length of <strong>the</strong> vehicle. Once loading was complete, <strong>the</strong> truck was inspected from <strong>the</strong> ground<br />
<strong>for</strong> loose or escaping soil or leaching water be<strong>for</strong>e leaving <strong>the</strong> load-out area. The load was <strong>the</strong>n<br />
covered with a tarp or o<strong>the</strong>r suitable covering using an automated pull-over mechanism from<br />
within <strong>the</strong> truck cab or a manual hand-crank. Only authorized personnel per<strong>for</strong>med <strong>the</strong><br />
inspection and all truck drivers were directed to remain in <strong>the</strong>ir vehicle until <strong>the</strong> vehicle had been<br />
properly decontaminated and had left <strong>the</strong> load-out area. Vehicle tires were brushed prior to<br />
leaving <strong>the</strong> load-out area to minimize tracking of soils to o<strong>the</strong>r areas within and outside each load<br />
line. The soil transportation vehicles were tare and weighed be<strong>for</strong>e and after soils loading,<br />
respectively. The trucks were weighed at a nearby off-site truck-scale at Route 5 Sand & Gravel,<br />
located approximately one mile west of <strong>the</strong> RVAAP.<br />
Federal Department of Transportation (DOT) regulations were followed during transport<br />
activities. The soil was DOT classified based on direct sample results or on previously collected<br />
data. The labeling requirements outlined in <strong>the</strong> WMMP (Shaw 2006g) were followed to meet all<br />
