MWMC FACILITIES PLAN <br /> <br /> Site impact <br /> Ease/impact of construction <br /> Flexibility for phased implementation <br /> <br />For each identified unit process a fact sheet was developed that rated each unit process <br />alternative against these criteria. A numerical score was assigned for each criteria and the <br />total score for each unit process was added up. The unit processes with the highest scores <br />were identified as preferred solutions, alternatives with intermediate scores were identified <br />as acceptable solutions, and some alternatives with the lowest scores were eliminated from <br />consideration. <br /> <br />A subsequent discussion and screening process narrowed the scope of unit processes <br />further. Although the identified preferred and acceptable solutions scored high in meeting <br />the staff's criteria, some of the solutions were not easily implemented, did not work well <br />with the existing infrastructure to meet future needs, or were simply cost-prohibitive. Unit <br />process solutions in these categories were eliminated from further consideration. <br /> <br />A final short list of unit process solutions to be considered for a more comprehensive <br />analysis was developed. Technical memorandums provide a detailed discussion of each <br />evaluation, and alternative comparisons. The remainder of this chapter summarizes those <br />alternatives analyses and provides insight into the selection of a systemwide alternative that <br />addresses all the facility needs. Each alternative analysis includes a monetary and identical <br />non-monetary evaluation. Non-monetary evaluations are based on the criteria shown in <br />Table 6.0-2. For each criterion, the alternative was given a score of 1 to 5, 1 being negative or <br />difficult, and 5 being beneficial. A total maximum score of 30 points is possible and a <br />minimum score of 6 points is possible. <br /> <br />TABLE 6.0-2 <br />Example of Non-Monetary Evaluation <br />MWMC Facilities Plan, Eugene-Springfield <br /> <br /> Alternative I Alternative 2 <br />Siting 5 1 <br />Constructability 5 1 <br />Performance 5 1 <br />Effect on Performance of Downstream Equipment 5 1 <br />Operational Flexibility 5 1 <br />Maintenance 5 1 <br />Total Score (30 points maximum) 30 6 <br /> <br />Scoring: 1 = Negative/Difficult <br /> 5 = Beneficial <br /> <br />$-2 MWMC_6.0_REV11.DOC <br /> <br /> <br />
