Mr. Cummings replied that the Well Master Plan would address this, but he <br />thought it could be six to ten wells, depending on the yield of those wells. Zone 7 is <br />looking for primarily emergency uses. The actual amount of normal production that <br />Zone 7 will pull out of the basin can be done with the existing number of wells. The new <br />wells will be used for an emergency supply, e.g. if Zone 7 were to lose the South Bay <br />Aqueduct for a month or two. Zone 7 could then turn its wells on and provide three- <br />quarters of the maximum day demands. The well capacity Zone 7 currently has is <br />sufficient for the long term average use from this basin, but there would additional wells <br />needed for emergency back-up. <br /> <br /> Mayor Pico asked how long before Zone 7 comes up with full implementation of <br />the salt management program. <br /> <br /> Mr. Cummings said it will be taking place between now and build-out. The first <br />phase has been pre-designed and now discussions are underway with the other retailers <br />and with LAVWMA because of the brine disposal. This is the first phase and the second <br />phase is scheduled for 2008 to 2010. If the water quality management plan comes in, <br />there would be another phase. <br /> <br /> Ms. Hosterman asked if this was between now and build-out of this community or <br />all of the communities that Zone 7 serves? <br /> <br /> Mr. Cummings said he is talking about the build-out of Zone 7. This Valley wide <br />operation and the groundwater basin are key parts of providing the storage for drought <br />proofing the community. The second phase completion for 2008 is because of the <br />resolution of the brine issues. This brine issue is part of the environmental review and if <br />a mitigated negative declaration comes out, currently drafted and in house, there may be <br />some folks that may think it will require more. The public review process will address <br />this issue. <br /> <br />Mr. Campbell asked about the increase being seen in the rates. <br /> <br /> Mr. Cummings said the first phase was built into the current rate structure. The <br />next phase, when the operation gets turned on and becomes energy intensive, there will <br />be a 2 - 3% increase for the average user. The connection fees have built into them the <br />capital costs of the facilities, but once they are built, then the operation of the facilities is <br />part of the ongoing rate impact. <br /> <br /> Mayor Pico said that when Zone 7 was discussing wellhead demineralization, <br />Zone 7 was encouraging the City of Pleasanton to address those kinds of issue. Is Zone 7 <br />planning to put demineralization equipment on the City wells? <br /> <br /> Mr. Cummings said when Zone 7 talks about this issue it is encouraging solutions <br />to this which are cooperative on both sides. Zone 7 is not planning on putting the <br />demineralization equipment on the City wells. <br /> <br />Pleasanton City Council 12 03/04/03 <br />Minutes <br /> <br /> <br />
