• • <br /> The sampling crew manager will assist the loader operator in locating the appropriate <br /> cell for each sample using the sample cell map in Figure 1 below. <br /> After the loader has extracted the material in the selected cell, the sampling crew <br /> manager will guide the loader to a designated tarp. Using visual cues the sampling crew <br /> manager will ensure the loader operator(s) deposits the proper quantity of material on <br /> the tarp. A shovel may be used to add material from the bottom of the cell to ensure the <br /> sample includes some heavy and small material that the loader bucket cannot collect. <br /> Pulling the tarp is a basic test used to estimate sample weight.' If it is determined that a <br /> sample is too heavy it may be lightened by removing vertical slices from the sample. If it <br /> is determined that a sample is too Tight it may be increased by removing or adding more <br /> material. It is important to add or remove all material in the slice from the top to bottom, <br /> to ensure that both small, heavy, and loose materials and large, Tight, and bagged <br /> materials are added or removed. <br /> Samples can be queued and stored on tarps until sorted but samples must be prevented <br /> from mixing with each other and with other material on the tipping floor. The sampling <br /> crew manager will place a unique sample placard on each sample for a photograph and, <br /> if the sample is not immediately sorted, for later identification. The placard is marked <br /> with a unique sample identification number and additional information (such as the date) <br /> used to identify loads in photographs and correlate load net weights with sample details. <br /> Each placard will be coded according to its corresponding materials stream. (e.g., 'RSS- <br /> 1' indicates the first load of Residential single- stream recycling). Each load will be <br /> photographed individually with the sample placard visible and legible. <br /> Figure 1: Sixteen (16) cell grid <br /> 8 <br /> 6 <br /> = <br /> - ._ ' 7 <br /> 5 ' "r ' 15 <br /> 4 <br /> _ ' 13 <br /> i 1 i' " - i <br /> I <br /> 11 <br /> , <br /> 9 <br /> 10 i <br /> Note: Cells 12, 14 and 16 are below cells 4, 6 and 8, respectively. <br /> 1 Samples of Commercial Source - Separated and Targeted Recyclable Materials, Single - Family <br /> Targeted Recyclable Materials, and Commercial Plant Materials shall weigh between one <br /> hundred and twenty five (125) pounds and one hundred and seventy five (175) pounds.
