Analytical Requirements

A tiered approach based on volume of soil will be used to determine the frequency of characterizing sampling.  A minimum of one soil sample will be collected for each approximate 500 cubic yards up to 1,000 cubic yards of soil.  If more than 1,000 cubic yards of soil is generated from the same source, the sample collection frequency will be reduced to one sample for each additional 1,000 cubic yards of soil up to 5,000 cubic yards thereafter.  The following sampling protocols will be used:

• Toxicity Characteristic Leaching Procedure (TCLP) VOCs & Total TCL VOCs

• TCLP SVOCs & Total TCL SVOCs

• TCLP Resource Conservation and Recovery Act (RCRA) & Total Metals

• Target Compound List (TCL) polychlorinated biphenyls (PCBs)

• TCL herbicides/pesticides

• Flashpoint

• Corrosivity

• Reactivity
