CEQA ADDENDUM: CHARLES MEYER DESALINATION FACILITY JUNE 10, 2015 PAGE 5 OF 87 1 INTRODUCTION 1.1 PROJECT BACKGROUND AND HISTORY In response to a challenging water supply crisis, the Santa Barbara City Council declared a Stage III drought condition in 1990 based on a projected water supply deficit of 47% for the water year 1990-1991. The City Council then directed City of Santa Barbara (City) staff to solicit proposals from private firms for delivery of alternative water supply in amounts between 2,500 and 5,000 acre-feet per year (AFY) no later than September 1991. The supplemental water supplies were to replace the potential loss of water deliveries from Cachuma Reservoir in the 1992-93 water years and replenish groundwater basins that were over-drafted on an emergency basis. Based on the proposals received, the City chose to move forward with the analysis and construction of the Charles E. Meyer Desalination Facility (Approved Project), located at 525 East Yanonali Street, to originally provide an emergency water supply. The decision to construct the Approved Project facility was a deliberative process that involved feasibility studies that evaluated alternative intakes and treatment technologies, plant capacities, and facility locations. The Approved Project was analyzed in two separate Environmental Impact Reports (EIR). The first of those EIRs, prepared in 1991, analyzed the construction and operation of the Approved Project as a temporary emergency facility (1991 EIR). After receiving bids, the City Council directed staff to negotiate a final contract with Ionics, Inc. to deliver a desalination project. The contract included the finance, design, construction and operation of a 7,500 AFY desalination facility (expandable to 10,000 AFY). The contract period was for 5 years with an option to renew for another 5 years. Construction of the Approved Project was completed and the facility was put into operation on March 2, 1992. Additionally, the City applied for and was issued a Coastal Development Permit (CDP) for the temporary desalination facility by the California Coastal Commission (CCC) on May 9, 1991 (Permit 4-91-18). The CDP was issued for a 5-year period. After operating for three months, in the spring of 1992 use of the Approved Project was discontinued when ample rain in March and April 1992 resolved the City’s drought situation. The City elected to place the Approved Project into a standby condition during the remainder of the contract term (through 1996), with the caveat that production of water could be restarted with a 1-year notice by the City. For the purposes of the environmental review in the 1991 EIR and permitting from applicable local and state agencies, the Approved Project was defined as a temporary, 5-year project. However, the treatment equipment was installed for a 25-year (active service) life-cycle and complied with all standards and building codes for permanent structures. After relief of the drought came in 1992, the City recognized that drought would be a reoccurring regional challenge. The City therefore began a review of its long term water supply situation. This was in part based on a 1991 election where City voters gave overwhelming support
