6. DEVELOPMENT AND EVALUATION OF ALTERNATIVES It would be financially beneficial to investigate adding the SIWF to the WPCF's NPDES permit to decrease annual permit costs. The cost-benefit analysis for this alternative is presented in Table 6,5.5-1. Alternative 2 - Sell the SIWF Alternative 2 is to decommission and sell the land. Advantages and disadvantages of this alternative are listed below. Advantages: Selling the SIWF would avoid the capital costs associated with the infrastructure on site Eliminates annual O&M costs Would eliminate future site liability Revenue could fund other costs Disadvantages: Lose a potentially valuable asset (land and existing facilities) related to the overall long- term strategies of MWMC's biosolids and effluent reuse program, as well as to potential regulatory changes. To receive the highest possible value for the site, decommissioning efforts will be required. This is based on selling the land as it is currently zoned (E-30, exclusive farm use). * Availability and proximity of land, if required in the future, may be scarce commodities. · Future cost for development of a site similar to the SIWF will be great. Alternative 3 -Convert the 14-acre Lagoon at the SIWF into a new Facultative Sludge Lagoon Alternative 3 consists of upgrading the SIWF lagoon to a new FSL. Under this alternative, liquid biosolids could be applied on site. It is also assumed that biosolids, if applied at the SIWF, would be applied on grass crops at the SIWF and that the existing land lease agreement would remain in place. The SIWF lagoon would become the fifth FSL. Advantages and disadvantages of this alternative are listed below. Advantages: · Provides additional sludge stabilization and solids storage, which may be needed in the future · Continued leasing of the land for local farming activity ensure that the site is continuously farmed using sound farm management practices · Maintains flexibility in MWMC's biosolids management program Disadvantages: · The FSL would be remote from the other four FSLs located at the BMF · Piping intercormections and pumping facilities would need to be installed between the SIWF and BMF · Potential for increased complexity of control strategies · O&M is remote from the BMF facilities MWMC_6.0_REVI1.DOC 6-47
