described in Implementation(e)concludes that landfill disposal of wastewater sludge is the only viable option." (c) Implementation(e)under Objective 1 in Sludge Disposal(Appendix C) should be revised, as follows: "e) Initial Wastewater Sludge Disposal Plan. Within one year after the startup of the permanent secondary treatment process,the Community Service District shall submit an Initial Wastewater Sludge Disposal Plan to the County and other appropriate agencies for review and approval. The Plan shall document the sludge characterization findings,a detailed - impact/benefit analysis of sludge disposal options,and a proposed sludge disposal method for the duration of the current specific plan." (d) The following new Implementations should be added under Objective 1 in Sludge Disposal(Appendix C),as follows: 'If) Sludge disposal options shall be evaluated as early as possible,not later than one year after the startup of the permanent secondary treatment process,to allow for early identification of disposal options. Evaluation shall include sludge characterization, survey of potential sites where sludge may be used as a soil amendment, and assessment of viability of the compost market. "g) In all specific plans where wastewater treatment sludge requires disposal, the specific plans — shall identify the proposed method(s)of sludge disposal for the duration of the plans. The CSD may subsequently adopt other sludge disposal options provided the new method(s)will achieve an equivalent or higher degree of environmental and public health protection, as determined by the County, and meets all applicable regulatory requirements. The County shall be notified of the proposed change in disposal method at least six months prior to implementation of the new disposal method. "h) If landfill disposal of the wastewater sludge were proposed, an agreement or"will serve" letter with a landfill that would accept the sludge for at least the next five years shall be provided with the initial Wastewater Sludge Disposal Plan or subsequent specific plan. If land spreading or dedicated land disposal were proposed, then guarantees of adequate acres for sludge disposal for at least the next five years must be provided. Provisions for sludge disposal shall be updated annually so that there are always firm provisions for disposal for at least five years into the future." Mitigation Measure M4.4.2-5 (a) A new Policy should be added under Objective 1 in Wastewater Reuse Program(Appendix C), as follows: — "d) The wastewater treatment and storage pond levees shall be capable of withstanding a maximum credible earthquake; ponds located within the 100-year floodplain shall prevent _ inundation due to levee failure along Old River or other nearby waterways,be capable of withstanding the effects of flooding,and shall not impair the structural integrity of existing flood control levees." (b) Two new Implementations should be added under Objective 1 in Wastewater Reuse Program,as follows: "j) The detailed design of the wastewater treatment and storage pond levees shall be included in the Reclamation Plan and initial Development Permit for the Wastewater Treatment Plant, and in all subsequent reclamation plans where additional ponds are proposed.
