Five samples (labeled Camp 10, Camp 11, <br /> Comp 12 , Comp 13 and Comp 14) were collected, stored and analyzed <br /> using the methodology described above. Sample points are shown <br /> on the attached Site Plan, Figure 2 .

Copies of the <br /> laboratory analyses, and the Chain of .Custody documentation are <br /> attached to this report. <br /> Based on TPH levels in the stockpiled soil of less than 100 ppm, <br /> the soil can be disposed of at an approved Class III. disposal <br /> site. <br /> A copy of this report should be sent to the San Joaquin Local <br /> Health District, and to the Regional Water Quality Control Board <br /> (RWQCB) , Central Valley Region. <br /> Should you have any questions on this report, please do not <br /> hesitate to contact me at (707) 746-6915. <br /> Sincerely, ! <br /> Kaprealian Engineering, Inc. <br /> i <br /> - t f <br /> Christina L.
