REQUESTS TO SPEAK ON LISTED ITEM: None. 2. UPDATE REGARDING COUNTY WATER AUTHORITY PURCHASE AGREEMENT WITH POSEIDON RESOURCES. The following document was distributed for this item and is on file in the Office ofthe City Clerk: • Desalination Overview and Update PowerPoint Presentation Ken Weinberg, Director of Water Resources for the San Diego County Water Authority, gave the update on the status ofthe Carlsbad Desalination Project, including project components (plant, conveyance pipeline, connection to Water Authority aqueduct, and improvements to Twin Oaks plant), and the parties Involved in the project construction and operation (contained In presentation referenced above). Mr. Weinberg also reviewed the challenges to ensuring reliable sources of water for the San Diego region, and explained the current water sources. He explained the contents of the proposed Water Purchase Agreement, which would allow Poseidon to permit, design, construct, own and operate the desalination plant through the 30-year agreement (WPA). He also noted that the Draft Agreement had been released for review to member agencies on August 22,2012, and contains 26 sections and 18 technical appendices. Mr. Weinberg explained that the contracts for each agency are uniform except for quantity, and will allow member agencies to purchase local supply directly from the Water Authority. Mr. Weinberg described the responsibilities ofthe parties as follows: • Poseidon - Permit, Design and Build the Desal Plant and Conveyance Pipeline; Operate and Maintain the Plant; and Supply Desalinated Water • Water Authority - Take or Pay for water if it meets specifications (48,000 acre feet per year minimum); Construct improvements to Twin Oaks Plant; Provide ability to receive desalinated water; and Operate and Maintain Conveyance Pipeline, Twin Oaks Plant improvements; and Pipeline 3. Page 1 He reviewed the project risks that would be transferred to Poseidon (construction, operation, maintenance and repair) and those that would be retained by the Water Authority (changes in law, cost of Encina improvement, bond financing interest rates, general price inflation, and electricity rates) He also outlined the termination and purchase options contained in the agreement, and the projected costs of the project to both Poseidon and the Authority. Mr. Weinberg also explained the estimated price increase per customer (7-10%) that would apply upon operation ofthe plant and reviewed the benefits that would be provided bythe construction and operation ofthe desalination plant. In response to inquiry from Mayor Hall regarding the possibility of smaller cities joining together to purchase desalinated water, Mr. Weinberg stated that would not be possible. In response to inquiry from Mayor Pro-Tem Kulchin regarding potential construction risks due to labor relations, Peter MacLaggan of Poseidon Resources stated that Poseidon is responsible for this as part of the construction, and has an agreement with the San Diego Building 8i Construction Trades Council for provision of labor for the project. Council Member Douglas commented regarding the energy related risks, but added that continuing to rely on the Metropolitan Water District for provision of water contains risks also due to regulations and future water shortages. Gordon Hess, of Gordon Hess & Associates, continued with the presentation. He explained the potential impacts to water rates and described the assumptions made to determine the impact to water rates if Carlsbad participates directly in the project. Mr. Hess reviewed the historical water rate trends and average rate increases from 1980 to the present. He also presented a summary of the preliminary forecast of future rate increases for water purchased from the Metropolitan Water District and for the purchase of desalinated water. In response to inquiry from Council Member Packard regarding risk to cost recovery relative to the plant, Mr. Hess explained that future electricity prices and possible cost overruns could affect future savings. He also explained that the water taken directly from the conveyance pipeline would not be subject to wheeling charges. Finance Director Chuck McBride continued with the presentation, providing additional details regarding the Local Supply Option, which would involve a commitment to guarantee a reliable local water supply for a thirty year period. He also described potential mandatory cutbacks from the Metropolitan Water District, based on conditions such as drought and insufficient supply due to restrictions on their other water supplies. Page 2 Mr. McBride reviewed the cost/benefit of purchasing desalinated water, noting the initial cost of desalinated water would be higher, but would gradually be less than water supplied by Metropolitan Water District over the life of the contract. In response to inquiry from Council Member Blackburn regarding costs of water per acre foot, Mr. Weinberg stated that the 2013 cost per acre foot will be $1259 plus $70 (RTS). In response to inquiry from Mayor Hall, Mr. Hess stated that the analysis did not include a review of possible increases in reclaimed water. In response to inquiry from Council Member Packard regarding other local water sources. Acting Utilities Director Chambers stated those would include groundwater, conservation, and other possible supplies to supplement the district's needs. In response to inquiry from Mayor Pro-Tem Kulchin, Ms. Chambers noted that the City of Oceanside has decided not to participate in the Agreement to purchase desalinated water. In response to inquiry from Council Member Douglas, Mr. McBride noted that there were several ways to address the initial 20% rate increase in the first year, such as smoothing the rates and using reserves to mitigate the increase. Staff noted that the Water Purchase Agreement (WPA) will be brought to the Board for consideration on November 27,2012. It was also noted that the matter will be on the agenda for the meeting of the San Diego County Water Authority (SDCWA) for their meeting on November 29,2012. PUBLIC COMMENT: None.
