1. As requested,site specific background for chromium will be determined by collecting samples of up to 3 locations <br /> on the property unlikely to be impacted by the stockpiling activities. The screening level for TPH-diesel range will <br /> be determined by multiplying the Water Quality Goal(100 gg/L)by a natural attenuation factor of 100. The <br /> screening levels will be using with the DI-WET analysis of the soils. <br /> 2. Phase I will include the sampling of the 6 locations of the monitoring well installation points(3 on the French <br /> Camp and 3 on the Lathrop Site—please note,this sampling has been completed but results have not been received <br /> from the laboratory)and the additional 6 borings at Lathrop and the 7 borings at French Camp. As discussed,if <br /> the sample results from the monitoring well installations indicate no impacts from the stockpiles,MonierLifetile <br /> may request a reduced boring number or a reduced sampling depth. <br /> 3. Phase I and Phase II will be combined with the background borings conducted in the same field exercise as the <br /> investigation borings. <br /> 4. All soil analysis will be completed using the DI-WET method. <br />
