Adequate storage is a key to supplying daily demand and preparing for emergencies. Citizens proposes to construct three storage tanks, two replacing the Schoolhouse tank (650,000 gallons each) and a new tank at the Portola site (100,000 gallons). Citizens contends that increased storage should receive high priority because future earthquakes may, as in the past, disrupt the ability to provide service in Montara. ORA argues that one of the Schoolhouse tanks should be postponed indefinitely. MSD agrees with ORA. Citizens agrees that if any project is deferred, it should be one of the Schoolhouse tanks, as ORA recommends.
We have no desire to reinvent the wheel in this proceeding. In D.97-12-097 we reached the conclusion that this tank should be deferred and conditions warranting its construction monitored. We have always anticipated that this second tank might not be needed. Therefore, we concur with ORA and MSD that this tank should not be constructed during this seven-year period unless circumstances change substantially.
