Ash John Smylie Call to Order Chairman Stiles called the meeting to order at 9:04 a.m. Minutes of August 24, 1977 JAC Meeting A motion passed (Zapotocky-Casler) to approve the Minutes of the JAC meet- ing of August 24, 1977 as submitted. Report on Coastal Commission Hearing Mr. Evans reported on the State Coastal Commission's hearing on Septem- ber 20, 1977 concerning Encina's Phase III application for coastal permit which was approved by the Regional Coastal Commission and then appealed. The major issues expressed by citizens' groups in opposition of granting a permit were concern with air quality and growth impacts in Vista and in the coastal area. Coastal Commission staff is concerned with development of coastal lands, sedimentation of lagoons and erosion of the bluffs in the coastal area. JAC -2- September 29, 1977 Encina representatives were directed to supply information to the Coastal Commission explaining why we are asking for additional capacity when our flows are only 9.7 mgd out of a capacity of 13.75 mgd. Additionally, they want an explanation of the commitments in L-eucadia and Carlsbad which will use up remaining capacity. Following Mr. Evans1 report, there was discussion on conditions which might be attached to the granting of a coastal permit. Several members suggested that one of the conditions would probably be restrictions on development of agricultural lands. The Coastal Commission will vote on the application at their October meet- ing. Reactivation of Plant at Leucadia County Water District Mr. Evans drew the members' attention to a letter, dated September 15, 1977 from Engineering Science, Inc. which addresses concerns previously expressed by JAC members in regard to reactivation of LCWD's secondary treatment fa- cility. The response to these concerns was as follows. First, LCWD will not exceed their existing capacity rights of 2.25 mgd at the plant. Secondly, total solids loading would be reduced by approximately 100 pounds per day. Mr. Evans stated the only concerns which remain are how the secondary solids would affect the digesters and the skimming system for scum removal on the sedimentation tanks. He recommended giving approval to LCWD, adding that close watch would be kept, and in the event of problems, LCWD could be re- quired to reactivate their digester and treat their own solids. Mr. Hanson introduced Greg McBain of Engineering Science, who gave a brief overview of Engineering Science's proposal and some positive aspects of the reactivation. Following a query by Mr. Zapotocky regarding time neces- sary to reactivate the digester, Mr. McBain stated it could be reactivated in a month's time if necessary. Mr. Zapotocky moved to approve Leucadia County Water District's request to reactivate with the understanding that if testing results show adverse ef- fects to the plant, that LCWD be ordered to disconnect immediately. Mr. Dominguez seconded the motion, which carried unanimously. Later in the meeting, Mr. Zapotocky requested that the foregoing motion be clarified to say that in the event of negative test results, LCWD will cease discharg- ing secondary sludge (not secondary effluent). Re-rating Report Mr. Oldsen reported on the progress made thus far on the re-rating study. The members reviewed a table summing up results of testing in the sedi- mentation tanks. Increased flows were simulated by shutting off one, then JAC -3- September 29, 1977 two, then three sedimentation tanks. Tests at increased flows did not in- dicate a suspended solids problem; however, grease and BOD results were inconclusive. A possible response to a grease problem could be chlorina- tion, and that testing is going -on right now. Later in Mr. Oldsen's pre- sentation, he added that physical removal of grease was another possible solution. Mr. Oldsen stated that additional problems are determination of a peak wet weather flow and the digestion operation. Digester No. 1, he commented, has an on-going foaming problem coupled with offensive odors, and No. 2 has an inherent weakness in the mixing and heating systems, which is a pre- requisite for increased loading in the digester. Mr. Oldsen explained the County plans to rate every component in the plant. Following chlorination testing, the hydraulic system will be reviewed and sludge digestion system analyzed. Brown and Caldwell will be consulted on the hydraulic review. A draft report should be ready by next month's JAC meeting. Water-saving Kits Mr. Dominguez announced the County has an opportunity to get 50,000-8C,000 water-saving kits, and he had been directed to suggest that the JAC agencies act as central distribution centers. It was the general concensus that Mr. Dominguez pursue acquisition of the kits provided there are no requirements for tracking them. Mr. Dominguez then left the meeting at 9:40 a.m. Operations and Maintenance Report Mr. Evans reported that plant personnel was presently experimenting with live steam injection directly into the digester to heat it. Continuous mixing is being done, and little new foam has developed. John Murk and Jerry Frieling of CM Engineering were introduced as members of a new CM office in Vista who have toured local plants and have asked to review Encina's records and reports regarding the digester problems. Following a question by Mr. Skotnicki on the propeller meter, Mr. Evans reported that direct readings were now being used from the propeller meter. However, he added that during the month, when San Diego County was asked to curtail water usage (due to the mishap at the Colorado aqueduct), a sharp drop in plant flows was noticed. Consequently, there is uncertain- ty, at this point, whether people responded to the plea for conservation or the meter is malfunctioning again. Mr. Evans concluded by saying the meter would be tested again. w JAC -4- September 29, 1977 Mr. Evans informed the committee that he had contacted a swimming pool manu- facturer regarding the possibility of designing some type of cover for the digester (which could be vented) to help control odors. Flow Report Mr. Evans noted that flows were up slightly from July. Vista flows, how- ever, went down sharply, adding that it could be a case of meter malfunc- tion. It was also pointed out that Vista had made their annual correction in their EDU count, and that adjustment is reflected in this month's report. Sulfide Condition Report The members briefly reviewed the sulfide report. Mr. Evans indicated the odor problems at Lanakai Lane Mobile Home Park have been corrected by seal- ing adjacent manholes. Expenditure Report At August's end, prorated budget total was $67,438 with actual expenditures of $53,695. Encina's .expenditures are almost right .or, line. Descriptive Brochure At the last JAC meeting, a subcommittee was appointed to look into the pos- sibilities of printing a descriptive brochure about the Encina facility. The subcommittee met and directed Mr. Evans to develop a sample of what type of booklet could be produced. A sample mock-up was passed around dur- ing the meeting. Mr. Evans explained that a brochure (such as Vista's monthly newsletter) in two colors could be printed at a cost of approximately $600 for 5,000. A full color photograph would add $200 to the initial cost. Subsequent printings would be considerably less as charges would be for printing and materials only. Several members suggested using the full color picture used on the mock- up. Mr. Evans pointed out that could involve additional cost if the rights to the photo had to be purchased. The addition of a logo could a.lso add to the cost. Mr. Schneider made the motion, which was seconded by Ms. Lash, that the General Manager be authorized to have the brochures printed (by the same printer Vista uses) on the same type of paper Vista uses in two colors with a full color cover page. c JAC -5- . September 29, 1977 Following discussion on distribution of the brochures, Mr. Schneider recom- mended, by amending his original motion, that 5,000 copies be printed for use at the plant and individual agencies pay for printing of any addition- al brochures which they might require. The amended motion was seconded by Chairman Stiles and unanimously passed. Adjournment There being no further business, the meeting adjourned at 10:22 a.m. The next regularly scheduled meeting will be at 9:00 a.m. on October 26, 1977 in the Conference Room of the Encina Water Pollution Control Facility.
