<br />Sample disposal <br />After the weight of all material in each sample is recorded on the tally sheet, the <br />sampling crew will move the sorted material to a location where it is safe and convenient <br />for the loader to remove. <br /> <br />Data management <br />At the end of each sampling day, the sampling crew manager will review all forms for <br />accuracy and completeness. Any issues shall be resolved immediately while the day's <br />work is still fresh in the mind. To ensure the tally forms are not lost before inputting the <br />data into an electronic form, copies shall be made of all completed forms and copies will <br />be kept in a place separate from the originals. One copy of the forms will be mailed or <br />hand delivered to the person inputting the data into an electronic form. <br /> <br />The appendices cover calculations, data collection forms, and an equipment list for this <br />study. <br /> <br />5. Sorting categories <br />All loads identified for sorting shall be sorted and weighed into the following two (2) <br />categories: <br /> <br />1) Contamination <br /> <br />2) Targeted Recyclable Materials, Source-Separated Targeted Recyclable <br />Materials, Organic Materials, or Plant Materials <br /> <br />6. Calculations <br /> <br />Estimates of Contamination and Targeted Recyclable Materials, Source-Separated <br />Targeted Recyclable Materials, Organic Materials, or Plant Materials will be calculated <br />using a method that gives equal weighting or "importance" to each sample within a given <br />stream. Confidence intervals (error ranges) will be calculated based on assumptions of <br />normality in the composition estimates. <br /> <br />In the descriptions of calculation methods, the following variables will be used: <br /> <br />. i denotes an individual sample. <br /> <br />. j denotes the material type. <br /> <br />. Cj is the weight of the material type j in a sample. <br /> <br />. w is the weight of an entire sample. <br /> <br />. fj is the composition estimate for material j (r stands for ratio). <br /> <br />. a denotes a region of the state (a stands for area). <br /> <br />. s denotes a particular sector or subsector of the waste stream. <br /> <br />. n denotes the number of samples in the particular group that is being analyzed at <br />that step. <br /> <br />Estimating the Composition <br />The following method will be used to estimate the composition of waste belonging to the <br />Commercial Source-Separated and Targeted Recyclable Materials, Commercial Organic <br /> <br />Facility Agreement, Attachment 2E <br />Contamination Measurement Methodology <br />Page 7 of 15 <br />
