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