Task 3 — Conduct Sorting Event Task activities will include the following: • Obtain the necessary equipment for conducting the sorting event. Throughout the sortin: -vent, the County will be asked to provide a skid steer/loader and operator to assist in pullin: amples, delivering them to the sorting location, and returning materials following the sortin:. ctivities. KCI will provide a mobile scale, customized sorting table, all sorting equipment ant tools, safety and protective gear, and fluids to keep workers hydrated. • Provide a Field Manager, Sorting Supervisor, and sufficient day laborers to - sist with the sorting event. If the County prefers to provide sort labor, the budget will be adj : ed accordingly. • Conduct the sorting event. The sorting event will be conducted over during the summer months.

Analy: is will be conducted in accordance with ASTM's Standard Test Method for Determinatio of the Composition of Unprocessed Municipal Solid Waste (D5231-92; Reapproved 2008). Ba -d on the quantity of waste delivered to the landfill from each generator sector annually, indi dual generator sector results will be combined to provide the overall composition of sol': waste delivered to the landfill for disposal. • Analyze the vis , al audit data for the bulky waste and C&D debris to calculate the percent by volume of eamaterial category. Volumetric percentages will be converted to percentage by weight bas' d on industry -accepted conversion factors. • Prepar- a draft report that provides the study methodology, summarizes the results of each sorti event and visual audit, and provides the annual waste composition for each generator sec or and for the overall county. Report appendices will contain individual sample data for each nerator sector. The report will also identify the types and quantities of potentially recyclable materials that are currently disposed. Review the draft report via teleconference with County staff; revise and finalize the memorandum based on comments from staff. 151
