disposal options,including discharge to Old River and piping the effluent to non-contiguous lands for irrigation, shall be considered,if necessary. If future specific plans propose an interim or permanent wastewater reclamation at a site other than the sites identified in the Master Plan,all the policies in the proposed Master Plan and all the adopted mitigation measures, shall be applicable to the proposed alternative reclamation site(s). Any alternative wastewater reclamation site shall also be subject to the permitting requirements of the Central — Valley Regional Water Quality Control Board and the Department of Health Services. Prior to the approval of any specific plan utilizing an alternative wastewater reclamation site not specifically identified in the Master Plan/Specific Plan I EIR, site-specific environmental review shall be performed(including but not limited with respect to human contact, biological impact, crop types,etc.) and additional mitigation measures will be adopted to mitigate any site-specific environmental impacts not previously addressed." — (1) Implementation(h)under Objective 1 in Wastewater Reuse Program(Appendix C) should be replaced, as follows: "h) Monitoring. A detailed Salt and Trace Metal Management Plan shall be submitted as part of the reclamation plan to ensure that irrigation with reclaimed water is a viable long-term disposal option and to ensure minimization of salts and trace metals that are discharged to — surface waters via the agricultural drains." (m)The following new Implementation Measures should be added under Objective 1 in Wastewater Reuse Program(Appendix C),as follows: "j) The location and design specifications for the wastewater storage ponds shall be provided in the Reclamation Plan.The location of agricultural drains within a one-half mile radius of the storage ponds and the sources and characteristics of soil that would be used to construct the ponds shall be identified. The design specifications shall address levee and pond bottom permeability, levee stability, and flood protection. "k) An estimate shall be made of the wastewater volume that may seep from the ponds, and an assessment of potential flow paths from pond seepage shall be determined for the interim and potential permanent reclamation sites. The result of the assessment shall be submitted to the CVRWQCB for deterrnination of whether agricultural drain discharge from land irrigated with reclaimed water would be regulated as a point-source discharge under the NPDES — program. The determination by the CVRWQCB shall be provided in the reclamation plan. If it appears likely that die CVRWQCB would regulate the agricultural drain discharge,then assurance that the discharge would be allowed must be documented prior to approval of the reclamation plan." (n) A new Policy should be added to Objective 3 in Wastewater Reuse Program as follows: "f) The project shall be constructed such that on-site wastewater reclamation could be practiced to the maximum extent possible upon the completion of an advanced wastewater treatment _ plant with minimal retrofitting of developed areas." (o) A new Implementation should be added to Objective 3 in Wastewater Reuse Program. "g) On-Site Reclamation. A reclaimed water distribution system shall be installed throughout the project upon initial development. The system shall provide for transmission of treated wastewater from the treatment plant to all public landscaped areas,parks, industrial and commercial areas,and other areas where reclaimed water could reasonably be used in the EDAW College Park at Mountain House Specffic Plan III Draft EIR Public Utilities 4.5-20 San Joaquin County
