The potential opposition to elements of the system, based on experience in implementation elsewhere and comments from the public and the CSWAC throughout the project. The potential for opposition is ranked as high, medium, or low. The methodology for evaluating each system was conducted based on the following steps. 1. Define system components. During June 1995, meetings were held with the LOG to define general system components. Based on the results of these meetings, three general systems were created. A series of clarifications were subsequently provided by the LOG to provide further detail necessary for evaluation. In some instances, WESTON was asked to provide the necessary details to complete the system definition. The resulting system descriptions are provided at the beginning of each subsequent section of this report. 2. Establish baseline system. Because much of the evaluation data for the three potential systems are based on extrapolation from the current system, a general understanding of all components of the current system was needed. Much of this information had been gathered as a result of previous project efforts. Additional information was gathered as necessary to complete this understanding. It is important to note that the quantities and composition of materials, costs, and current diversion of the existing system were developed based on information provided by the LOG prior to the preparation of this report. Baseline quantities were derived from composition analyses performed by the LOG. It was assumed that only the primary MSW materials would be included for this analysis, while construction and demolition debris, hazardous waste, and infectious waste would be excluded. The excluded C&D debris includes clean wood waste, treated wood, and other inert materials. Combining the composition data with actual disposal and recycling data from 1994 allowed for the development of baseline generation quantities, which were used in the systems diversion model for this report. Additional information provided by the LOG allowed for a breakdown of quantities among the commercial, single-family urban, single-family rural, and multi-family sectors. The resulting evaluation model for these three systems has the flexibility to allow adjustments to these baseline data if additional information becomes available or solid waste trends change. 3. Evaluate systems to determine quantity of materials diverted. To create an equitable baseline for comparison of diversion potential, the existing system's waste generation, including disposal and existing recycling, is used as the basis for measuring diversion potential in each of the three systems. Three components of diversion were estimated for each NOR/K\WP\10790\RPKDL001.WP 2 10/95
