Screen Alternatives Before Evaluating <br /> You need consider only potentially viable alternatives. If the list of candidate source reduction <br /> measures is extensive,you may screen the measures before beginning any formal evaluation. <br /> The screening procedure can range from an informal review to quantitative decision-making. <br /> This review serves to eliminate suggested measures that are marginal or inferior without <br /> detailed and more costly technical and economic feasibility study. However,the Plan must <br /> include;a rationale for rejecting each alternative that you do not analyze in detail('Title 22; <br /> section 67100.5(o),CCR). <br /> Optional Source Reduction Matrix <br /> The evaluation of potentially viable source reduction measures required by the regulations can <br /> be documented in the Plan by use of a matrix for recording scores and ranks,as shown in Table <br /> .This method Prov ides a means for you to record the weight assigned to the important factors <br /> that affect waste management at your site. The matrix provides a quick visual representation <br /> of the factors affecting various source reduction measures. <br /> This method involves three steps. First,you determine what the important factors are in <br /> €enns ofthe source reduction program goals and the overall policies specific to your site, While <br /> these factors may differ widely between industries in number and type,you must consider the <br /> factors mandated by SB 14(see Section 5.5 of this Guidance Manual). Examples of optional <br /> factors you may wish to include are: <br /> • Reduction in waste hazard(toxicity,reactivity,etc.) <br /> ° Previous success within the organization <br /> Previous success in other industries <br /> Implementation period <br /> Ease of implementation <br /> Second,you must evaluate each factor listed. The rationale for each factor must be given. <br /> Optional weights can be assigned to each of the factors in relation to their importance. if you <br /> assign a weight to a factor,a rationale for each weight you assign must be included in your Plan. <br /> if"the factors arcranked according to importance,the rationale forthe importance ofeach factor <br /> should also be given. <br /> d_ast,rate each proposed source reduction measure for each of the factors. Recycling, <br /> ar4d treatment alternatives can be rated at the sante time. The score of each source <br /> r oduetionmeasure for a particular factor is multiplied by the weight assigned to that <br /> factor. Determine a measure's overall rating by the sum of the weighted scores for all. <br /> [rectors. . <br /> Note that you are riot required to use a matrix. It is proposed as a convemencc to you and <br /> not meant to be.a constraint, In some cases where a limited nuernber of potentially viable <br /> ntrsasures exist, a matrix might not improve the narrative presentation of your feasibility <br /> z!nalysis on each source reduction measure evaluated in your Plan. <br /> � 39 <br />
