DIRECTOR June 17, 1970 City Council City of Carlsbad 1200 Elm Avenue Carlsbad, California 92008 Gentlemen: PROJECT 7505 - ENLARGEMENT OF ENCINA WATER POLLUTION CONTROL FACILITY The plans and specifications for the subject project have been completed and were approved by the Joint Advisory Committee on May 20, 1970. In accordance with Section 6 of the Third Supplement to the Basic Agreement between Vista Sanitation District and the City of Carlsbad, dated March 22, 1965, it is now necessary that you approve the attached plans and specifications. The Vista Sanitation District should be notified of your approval. It will be recalled that the San Marcos County Water District was permitted to become a participant in the Joint Sewerage System by terms specified in the Third Supplement. This agreement became effective on June 27, 1968, when San Marcos deposited the specified funds with Vista to be held pending the enlargement of the Encina Water Pollution Control Facility. San Marcos commenced using the Encina plant and ocean outfall in August of 1969. The decision to proceed with the en- largement, which will be accomplished at no expense to the other three owners, was made in May of 1969. According to the terms of the agreement Vista was specified as the contracting agency to carry out the construction program. The funds provided by San Marcos have been deposited by Vista and are drawing interest. An application for a thirty-three percent Federal Grant has been filed and is expected to be received. A summary of project costs and funding is enclosed. A copy of the tentative time schedule being used as a guide for proceeding with the project is also enclosed for information purposes. You will note that after approval of the plans by all parties Vista must await the receipt of a Grant Offer from the Federal V/ater Pollution Control Administration before advertising for construction bids. We will forward all necessary material as soon as it is available to the State Water Resources Board and the Federal Water Pollution Control Administration to expedite this matter. When the Grant Offer is received it is recommended the Vista Sanitation District advertise for bids. Because of a steady increase in the daily wastewater flow being processed at the plant it is very important that the enlargement program proceed on schedule. You CIty Counc i1 City of Carlsbad -2- June 17, 1970 will note it is anticipated the construction is estimated to be completed by August of 1971. If this schedule is maintained there should be no problem in being able to adequately treat the projected increase in wastewater flow. It is of interest to note that the proposed enlargement will increase plant capacity from 4.5 to 6.75 million gallons per day (mgd) upon completion. By agreement San Marcos will own 1.2 mgd of total plant capacity. Each of the other owners will receive a dividend of increased capacity from the remainder of the 2.25 mgd enlargement because of the transfer of ownership of certain basic items, such as site, roads, operation building and piping, that would automatically serve San Marcos but were owned by the other three parties. Vista will gain 0.50 mgd, Carlsbad 0.43 rngd and Buena 0.12 mgd in plant capacity rights as a result of the enlargement . Very truly yours, 'BERT V.
