President Nejedly called the meeting to order and requested that the Secretary call roll. 1. ROLL CALL PRESENT: Members: Hockett, Lucey, McGill, Menesini, Nejedly ABSENT: Members: None a. PLEDGE OF ALLEGIANCE TO THE FLAG Board and staff joined in the Pledge of Allegiance to the Flag. 2. PUBLIC COMMENTS None. 3. CAPITAL IMPROVEMENT BUDGET PLANNING WORKSHOP Director of Engineering Ann Farrell stated that staff met at length with the Capital Projects Committee prior to today’s workshop. They had some good suggestions, including presenting the projects first and the financial information later in the presentation. She stated that 2008-09 expenditure recommendations fall into two categories: baseline expenditures, and extra expenditures for capacity and regulatory needs. Baseline for renovation runs at about 1 percent of total estimated assets, or $27 million. $11.2 million has been budgeted for capacity and regulatory expenses, for a total expenditure of $38.2 million. The Treatment Plant Program consumes a large portion of the budget, and includes several large projects, including the Aeration Air Renovation project, the Sludge Truck Loading Facility project, and some demolition work on the plant site. The Aeration Air Renovation project is necessary because of increasing aeration loss, which is taxing the capacity of the steam turbines and electric blower. Air loss has increased significantly over the last six years. Three contractors tested innovative repair techniques each of which would correct the problem, one using expanding grout injection and two applying coatings under positive air pressure. Staff proposes to bid the three approaches against each other to obtain the best price. The repair should have a ten- Book 57 - Page 42 Board Minutes of November 29, 2007 year life, and is recommended rather that installing a new diffused air system, which would be considerably more expensive. The Sludge Truck Loading Facility project addresses disposal of sludge, should one of the incinerators need to be taken down unexpectedly. It would take several weeks to activate the second incinerator, and sludge would need to be disposed of in the interim. Twenty to thirty truck loads per day would need to be removed if the incinerators were not available. Sludge would be hauled to a landfill. The landfills will only accept sludge during the day and sludge would have to be stored at night, as well as over the weekend and holidays. The proposal is to install a cake hopper for overnight storage, retrofit the existing tank for liquid storage, and install an observation platform and wash down facility. President Nejedly asked about storage capacity and expressed concern that the storage capacity is insufficient. Ms. Farrell described the demolition project, stating that the old primary tanks need to be demolished to make room for future primaries, and the abandoned lime storage silos demolished to make room for the Primary Odor Control. She described innovations in the Treatment Plant Program, including developing innovative approaches to sealing leaks in the aeration basins, piloting testing processes for mercury removal, conducting green house gas inventories, and presenting papers at conferences. Member Hockett asked to be provided with the titles of the papers and the conferences at which they will be presented. With regard to the Collection System Program, the largest program, money will be spent in four areas: renovation, capacity, pumping station/force mains, and regulatory compliance/planning. The majority of funding will be spent on renovations and the A-Line Phase 2A project, a large part of which will be reimbursed by the City of Concord. She described the Camino Pablo Trunk Sewer Improvement project, from Flush Kleen Pumping Station to short of Miner Road. The Miner Road Trunk Sewer Improvements have been deferred for one fiscal year. The Sewer Renovation TV Program will TV 1447 miles of public gravity lines. Nine hundred miles have been TV’d to date, which is approximately 60 per cent of the total. The initial TV program will be completed in 2-3 years. She described how pipe defect scores are calculated and addressed. Ninety-two per cent of the pipes that have been TV’d to date are in relatively good condition, but there are still many miles of pipe that need renovation. She stated that it would take about 26 years to renovate all 6, 8 and 10 inch pipes with rating greater than 5,000, indicating poor condition, at current production rates. Staff will continue to look for improved efficiency and process improvements. Innovations in the Collection System Program include use of trenchless technology, development of geographical data integration platform for the collection system, and use of in-house design, construction management and right-of-way staff. Book 57 - 43 Board Minutes of November 29, 2007 The General Improvements Program funds basic programs such as the equipment budget, the information technology plan, and miscellaneous building improvements. The new Collection System Operations building will also fall under this program. Recycled Water Program highlights include deferring the A-line project and focusing on developing a strategic approach to maximize year-round recycling for industrial and other purposes. The total proposed Fiscal Year 2008-09 Capital Improvement Budget is $38.2 million. Total proposed Capital Revenue is $39.8 million, of which the City of Concord will pay $11.2 million for their portion of the A-line project. The Sewer Construction Fund balance will be about $52 million at the end of the fiscal year, based on these preliminary budget figures. Ms. Farrell stated that last year the Board and staff talked about an $11 raise in the Sewer Service Charge, which staff feels will be adequate. Future rate increases should be similar in nature and will fund the program as described, including $15 million for mercury removal and $13 million for the CSO building. Bond financing has been included in outlying years for construction of the primary sedimentation tank expansion. She stated that the Board’s role in the Capital Program is ongoing. Board approval is also needed for award of construction projects over $15,000, construction change orders over $50,000, and consultant contracts over $50,000. She concluded that Board concurrence is requested that the proposed preliminary expenditure figures for 2008-09 and subsequent 9 years are acceptable, and concurrence that relative emphasis and allocation of expenditures between the four programs is acceptable for development of the 2008-09 Capital Improvement Budget and Ten-Year Plan. Member Menesini asked how priorities are established. Ms. Farrell explained how priorities are developed. President Nejedly stressed the importance of repairing pipes and his desire to avoid overflows whenever possible. Member Lucey requested that staff provide copies of technical papers District staff presents at conferences. Member Menesini requested that staff try to obtain additional publicity for the District. Member McGill asked whether the District could be more aggressive with regard to the renovation program. Ms. Farrell responded that good progress is being made, and the estimated 26 years it will take to complete the program is an extrapolation of the information obtained so far. Book 57 - 44 Board Minutes of November 29, 2007 Member Lucey requested that staff develop information comparing the District's program and rate of pipe renovation to other wastewater agencies. In response to a question from Member Menesini regarding monitoring upcoming regulatory requirements, Ms. Farrell stated that Director of Plant Operations Doug Craig monitors that and also attends regulatory committee meetings. She stated that one issue the District may face in the future is the requirement to remove nutrients. General Manager James Kelly stated that staff will come back to the Board with information regarding potentially expediting the renovation program, and comparisons with other Districts as requested by Member Lucey. Staff recommends the renovation program as outlined on November 29, 2007 and that this information will be considered in the development of the Capital Plan and Budget for Fiscal Year 2008-09. 4. REPORTS AND ANNOUNCEMENTS None. 5. ADJOURNMENT There being no further business to come before the Board, President Nejedly adjourned the meeting at 2:43 p.m. Ifu4 b,J. It tI- Barbara D.
