Mountain House Specific Plan III — ........................................................................................................................................................................... occur and shall be considered to the extent economically feasible by the Mountain House Community Services District(MHCSD). Wastewater Treatment Plant:The MHCSD has secured two discharge permits from the Central Valley Regional Water Quality Control Board(CVRWQB),one to discharge to Old River 5.4 MGD on a year around basis,and the second to discharge on land 2.6 MGD.The land disposal permit is being used at this time so that a history of effluent quality analysis can be established This history is needed as part of a detailed analysis of effluent disposal to Old River that is required by the river discharge pemrit.The MHCSD expects to have the detailed analysis completed within the next two years. As of March 2004,the present Waste Water Treatment Plant(W WTP)has a treatment capacity of 0.45 MGD. Tertiary treatment is achieved through aerated lagoons,and other enhanced treatment processes.Effluent is _ disposed on land directly north of the plant site. The W WTP is currently(March 2004)being enlarged to a capacity of 3.0 MGD.The first two of the eventual four sequencing batch reactor(SBR)units are being constructed,and the MHCSD expects the project to be completed by January 1,2005. The expansion is needed to keep pace with the residential development of the Mountain House community. 13.4.2 Specific Plan III Description Phased expansion of the W WTP will be required to serve the Specific Plan II and Specific Plan III lands ` within the community. The scope and schedule of additional phases will be determined by the MHCSD in conjunction with the phased development of the Specific Plan III area. — As permitted under existing discharge permits granted by the CVRWQCB,either land discharge,Old River Discharge,or a combination of both will be utilized during the implementation of Specific Plan III. The existing land disposal permit is for use on property owned by Trimark;therefore,only to an extent to which agreement is reached with Trimark may any quantity of effluent generated by Specific Plan III be disposed of on these lands. Accordingly,GNK,the main developer of Specific Plan III,has secured the off-site Pombo property located at the southeast corner of Mountain House Parkway and Byron Road. See Figure 13-1. The Pombo property is being held for potential use as a reclamation site for Specific Plan III treated effluent, subject to agreements with other Specific Plan III landowners and approvals from MHCSD,CVRWQCB,the — affected irrigation districts and other affected agencies. Specific Plan III and related environmental analysis recognizes and by reference incorporates the findings, approvals and conditions of the East Altamont Energy Center(EAEC)by the California Energy Commission 13-6 Draft 03114/06 ...........................................................................................................................................................................
