Instruct the ioader operator to ca�ttue recyclable materials from two randomly <br />selected cells in the gzad— one frorn the tap half of the load and one from the <br />bottom hal£ These two cells should be raudornly selected prior to sampling using <br />a randorn number gezaerator. The desued cell numbers should be written on each <br />load's data sheet (see Attachment C). <br />3. Mi�c the recyclable materials extracted froxn the tvc�o cells on a hard, flat surface. <br />Insiruct #he loader operator to mv� the recyclables so as to distribute the various <br />materials tlazoughout the pile (i.e., �rst mix the recyclables back and forth in one <br />direction, then take recyclabie materials from a cross-section af the pilc <br />perpendicular to the mixing direction) to ensure a representative sample (see <br />Figurc 2 below). <br />Mix —> <br />Extract Sample for Sorting <br />Figure 2-- Mixir�g and Extracting Waste <br />' The r►umber of cells in this grid can be adjusted downward for small loads_ For example, a small load <br />can be divided in,to eight cells instead of ] 6 to ensure that a sufficient amount of recyclable materials <br />(between 200 ar�d 300 pounds per cell) is captured for sampling. <br />B-4 R.
