General conclusions regarding the SIWF can be grouped into three categories: <br /> <br /> Financially - the proximity to the BF and BMF and the value of the land will help reduce <br /> costs in the future for any expansion of the current treatment and reuse program. <br /> <br />· Politically - the current program and facilities are accepted by the surrounding <br /> community. Siting and construction at another location will likely incur additional <br /> regulatory costs and obstacles. <br /> <br />· Strategically - the SIWF lagoon can provide additional storage for sludge, effluent, or <br /> supernatant as these needs occur in the future. The land itself offers a significant buffer <br /> capacity and a strategic location for reuse of effluent, biosolids, BFP pressate and/or <br /> supernatant. <br /> <br />Based on the above conclusions and the previous discussion of the alternatives, the <br />following recommendations have been made: <br /> <br />· Selling the land is not recommended. <br /> <br />· Alternative 4 is the preferred alternative. A reclaimed water pipeline is already in place, <br /> and with fairly minimal additional investment it could receive effluent. The secondary <br /> option within this alternative is to implement the modifications that will also allow the <br /> site to receive liquid biosolids. <br /> <br />· Dewatered biosolids could also be applied to the site at any future time. <br /> <br />· At a minimum, MWMC should continue to lease the land and attempt to reduce its <br /> permitting fees at the site to make the lease more profitable. <br /> <br />· Because the need for effluent or liquid biosolids storage is not currently required based <br /> on other analyses, upgrading the FSL for storage purposes is not recommended at this <br /> time. <br /> <br />6-50 MWMC_6.0_REV11.DOC <br /> <br /> <br />
