Once the value of existing assets is allocated across the four capacity parameters, the next step is to determine the value of available capacity. Table 6 presents this calculation, showing the allocation of existing system asset value to growth - based on the percentage of available capacity shown in Table 4 (column b). The Table 6 allocation takes an additional step of classifying available capacity into liquid stream and biosolids (a line item in Table 5), due to the different availability of capacity for biosolids processing relative to that of other processes. Table 4 shows available capacity percentages for liquid stream processing; a similar process was undertaken to derive the available capacity for biosolids processing, the results of which are summarized in Table 6 (with more details shown in SDC Methodology Appendix C, Table C-3). Table 2 consolidates the growth costs by parameter (with BOD and TSS each receiving 50 percent of the biosolids costs shown in Table 6.

This process is shown schematically in Figure 3 (as described in the SDC Methodology). As the figure shows, the process begins with an analysis of the 20-year project list.
