At least one (1) <br />composite sample shall be collected from each inactive, uncovered storage <br />pile within 24 hours of excavation. Samples are not required if the soil is <br />uncontaminated. <br />6.2.1 A composite sample shall consist of one sample taken from the center <br />of each of four (4) equal sectors of the area required to be sampled <br />SJVUAPCD 4651 -4 12/17/92 <br />
