P N RODUCT(ON Orange County Solid Waste Management ( OCSWM) contracted with the H.W. Odum Institute for Research in Social Science at the University of North Carolina — Chapel Hill (Odum) to assist with the design and analysis of a survey of users of the County's five Solid Waste Convenience Centers (SWCCs). The primary purpose of the survey was to collect data with which to apportion the usage of the SWCCs into two parts: usage by residents who live in the incorporated areas of the county, and usage by residents who live outside the incorporated areas.. Information about recycling behavior and preferences was also collected. Odum statisticians worked with OCSWM staff to devise a sampling and data collection plan to provide a "snapshot" view of SWCC usage for a finite time period. OCSWM staff chose a time period that was free of holidays or other events that might cause aberrations in SWCC usage, and implemented the data collection plan. OCSWM staff entered data from the collected surveys into an application provided by the Odum Institute, and Odum statisticians analyzed the data and wrote this report. The following sections describe the survey instrument, sample design, and data collection procedures for the survey. SURVEY INSTRUMENT OCSWM staff drafted the questions to be asked in the survey. Odum reviewed the draft for adherence to best practices in survey methodology (clarity, unbiased wording, completeness of response categories, etc.) and provided assistance with forms design. A copy of the questionnaire is included as Appendix A. IN /OUT OF TOWN LIMITS The first and most important survey question asked the customer "Do you live within the town limits of one of the towns ?" Though seemingly a straightforward question, a significant number of Orange county residents do not know whether they live inside town limits. Therefore the survey form itself and the training of the data collectors focused on additional questions and techniques to confirm /clarify the customer's response. The first clarification question asked whether the customer has curbside recycling available to them. Unless they live in an apartment, the answer should be "yes" for all customers who live in the incorporated areas; if it was not, the data collector was trained to delve further by asking the customer's street name and consulting a list of street names in the incorporated areas in
