<br />These steps are described in more detail following the definitions of roles. Each step is <br />the responsibility of a specific person or group of people as follows: <br /> <br />. sampling crew manager-responsible for selecting samples, working with <br />Operator and the sampling crew, quality control, and compliance with Facility <br />regulations. <br /> <br />. sampling crew-responsible for sorting samples. <br /> <br />. facility manager-responsible for coordinating with the sampling crew manager. <br /> <br />. tipping floor staff-responsible for identifying loads potentially contaminated <br />beyond the acceptable threshold, creating a designated sampling and sorting <br />area, and ensuring segregation of selected loads in that area. <br /> <br />. loader operator(s)-responsible for segregating the selected the load from other <br />loads in the designated sampling and sorting area. <br /> <br />Safety training and staff coordination <br />When the sampling crew manager and the sampling crew arrive at the Designated <br />Transfer and Processing Facility they will participate in any required safety training and <br />put on all required personal protective equipment (see the equipment list shown in <br />Appendix 3). The sampling crew manager will also walk through the process of <br />extracting samples from the designated load with both the loader operator(s) and the <br />tipping floor staff. <br /> <br />Sampling and sorting area designation <br />With the input of the tipping floor staff and the loader operator(s), the sampling crew <br />manager and sampling crew will set up in the designated sampling and sorting area near <br />the tipping floor. The sorting area should be in a location near the load to be sampled <br />and from which the loader can safely remove samples after sorting. <br /> <br />Sample selection <br />Five (5) cells will be random.ly selected for sampling using a random number generator <br />for all material streams except commercial organics. Fifteen (15) cells will be selected for <br />the commercial organics material stream. <br /> <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 /> <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 /> <br />Pulling the tarp is a basic test used to estimate sample weight.1 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 /> <br />~;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. Samples <br />of Commercial Organic Materials and Single-Family Organic Materials shall weigh between one <br />hundred and seventy five (175) pounds and two hundred and twenty five (225) pounds. <br /> <br />Facility Agreement, Attachment 2E <br />Contamination Measurement Methodology <br />Page 5 of 15 <br />
