Comprehensiv e Review of S olid W aste Collection and Disposal Options v2.1 A -2 10/22/12 The Town’s current commercial rates are presented in Exhibit A-1. The rates are structured as a function of the size of container and the frequency of pickup. The methodology used by SCS to evaluate the Town’s commercial collections system costs and rate structure is summarized below: 1. SCS prepared an annual budget estimate for residential and commercial solid waste services for FY 2012-13, based on the Town’s budget structure (see Exhibit A-2). SCS pro forma budget has very minor differences from the Town’s draft FY 2012-13 budget because of differing assumptions on waste quantities, and other minor adjustments; however, these differences are not material. 2. SCS then allocated personnel salaries and budget line item costs to their respective residential and commercial functions based on our understanding of the Town’s Solid Waste Services Division organization. Exhibit A-3 shows the assumed top-level residential and commercial cost allocations. 3. SCS then further subdivided the allocated commercial sector costs by allocating these commercial costs into two (2) separate categories: commercial-multi-family customers and commercial-businesses customers based on estimated volumes of waste collected from each commercial category (e.g., multi-family, businesses, schools, etc.) (see Exhibit A-5 and Exhibit A-6). 4. SCS evaluated the Town’s commercial customer database and compiled the projected theoretical collection capacity per year in cubic yards and tons for each account type (e.g., business, restaurant, multi-family, etc.). The total collection capacity for each account type was calculated by adding the total number of containers of each size (i.e., 2, 4, 6, and 8 cy) for all collections accounts and including the collection frequency (i.e., 1 to 4 days per week). SCS calculated a total collection capacity of 6,038 cubic yards per week. 5. Using these collections data and the Town’s projected Commercial Collections costs, SCS calculated the cost to pick each container and a cost per cubic yard for collection and disposal, as a function of container size and collection frequency. From these data, SCS developed a pro forma Commercial Collections rate table for comparison to the Town’s existing rate structure (see Exhibit A-7). 6. Next, SCS assessed the “theoretical collection capacity” of the total number of dumpsters dispatched compared to the actual quantities of waste collected (in tons) to assess utilization factor of collection capacity (see bottom section of Exhibit A-5). 7. SCS estimated the rate for collecting a single dumpster to be based on allocated costs and the assumption that the dumpster is 70% full (see Exhibit A-8).
