Report on Proposed Raising of VC Outfall Sewer by State Division of Highways and Citron Development Mr. Cook presented an analysis of the filling over the .Vista-Carlsbad outfall sewer. Considerable discussion ensued. Mayor Dunne indicated that response from Citron will probably be very slow, and that the affected agencies should proceed with repairs and follow up with collection from Citron, as may be possible under the agreement. 3. 0 & M Reports for January 1973 4. Jim McKay indicated that there have been some possible errors in metering the flow from San Marcos. It may be that voltage from SDG&E is not within tolerance. Further checks will be made. Burroughs has been operating satisfactorily. It appears Kearfott is making progress in handling the heavy metals. A brief discussion of the work with the Division of Highways at the Buena Vista pump station was presented by Mr. Cook. He suggested that operator plant fast-growing screening landscaping around the site with treatment plant forces. A good job has been done around the treatment plant. A sprinkler system will probably be required; this may be in- cluded as part of the next year's budget. Preliminary Budget for 0 & M for 1973-74 Major factors discussed included: salary; Encina facility staffing to provide full plant attention from 7am to llpm, 7 days a week; industria waste surveillance program; ocean monitoring; safety program as affects by OSHA; waste water transmission; miscellaneous cost increases such as increased consulting to support EPA dictums. Mayor Dunne raised a question whether item E2, which is mainly for operation of the Ponto ' pump station, could not be included under Section A. The staff will ! cMinutes of Encina J<?Kit Sewerage Agency Feb. 21, 1973 Page 2 £.

Progress Report on 1972 Enlargement of EWPCF and Ocean Outfall Mr. Oldsen indicated that the Proposition 20 application would be submitted 22 February. There is still considerable doubt as to whether public projects will obtain preference in priority. It was recommended that a letter be directed by the operator to the Commission requesting special handling in view of the federal requirement for construction within 90 days, and the effort which has been made in the past to file the application. Brief discussion was held regarding capacity needs by the various agencies. Leucadia County Water District and San Marcos County Water District are both nearing the ultimate capacity which they are entitled after expansion. 6. Progress Report on Preparation of Technical Report Mr. Clarke outlined the various aspects of the technical report. The State Quality Control Board has required considerable detail. He indicated that present effluent does not meet ocean discharge require- ments for copper, zinc, or chromium. The remainder of heavy metal requirements are being met. It is the general conclusion of our consultant that the requirements which we cannot meet are not founded in fact, and there is no indication that the present plant operation is causing any problems to the ocean. Application will be made to the Water Quality Control Board for relief of these require- ments. At this point, it boils down to a "wait and see" situation to determine if logic can prevail. Higher degree treatment was discussed; ferric treatment and activated sludge were two alternatives. Initial cost of activated sludge is higher and annual 0 & M costs are approximately equal. The major cost for operation of activated sludge is for increased power which would be required. Primary or ferric treatment will probably be more failsafe regarding odors when compared to activated sludge. This is the consensus of the staff. 7_. Progress Report on Interim Connection with the City of Oceanside A motion (Mahr-Cook) was made to request Oceanside to limit their flows to 100,000 gallons per day. This is due to increased flows from Vista and decreasing excess capacity in the Buena Vista pump station. 8_. Status report on Construction of Ponto Interceptor Sewer and Considera- tion of Electrical Power to Serve Pumping Station It was moved (Blakesley-McKay) that permission be given for a temporary overhead line as indicated on the submitted drawing, subject to under- grounding of the line prior to 1 July 1973 and the further condition Minutes of Encina Jt Sewerage Agency Feb. 21, 1973 Page 3 8. Status report; construction of Ponto sewer, cont'd. that all power from the north be removed and a permanent power source for the power connection be taken from the south side of the site as soon as the power source is available at that side. 9. Request for Authorization to Purchase Certain Minor Capital Outlay Items with Fiscal Year 72-73 Budgeted Funds It was moved (Mahr-Annin) that those items listed in the Department of Sanitation and Flood Control's letter of 12 Jan. 1973 be approved. 10. Set Date for Next Meeting The next meeting will be held on 21 March 1973 at 9:00am. Respectfully submitted, Hunter T. Cook HTC/de
