President Ooten called the meeting to order at 10:30 a.m. DIRECTORS PRESENT: Bob Ooten, Jim Ferryman, Jim, Art Perry(Director Perry attending as an observer only and did not participate in discussions.) STAFF PRESENT: Scott Carroll, General Manager; Rob Hamers, District Engineer; Yefim Tsalyuk, Senior Engineer; Joe Limon, Senior Inspector, Joan Revak, Clerk of the District OTHERS PRESENT: Victoria Pilko, Project Manager and Jim Herberg Assistant General Manager & Director of Engineering, Orange County Sanitation District STANDING REPORTS There were no sanitary sewer overflows (SSOs)to report. Project#101 West Side Pumping Station Abandonment Mr. Jim Herberg, Assistant General Manager & Director of Engineering from Orange County Sanitation District, and Victoria Pilko, Project Manager, attended to discuss the project timetable on the West Side Pumping Station Abandonment (OCSD Southwest Costa Mesa Trunk). Mr. Herberg and Ms. Pilko were requested to review the new timetable for the project that shows a 2019 project completion while previous information led the Sanitary District to plan on a completion date closer to 2016. President Ooten stated the Sanitary District has been using 2016 as a target date for completion of its sewer facilities for the project and the extra years require an additional commitment to keeping the existing pumping station and force mains in service. Ms. Pilko explained the 2019 date was a worst-case scenario and previous estimates were not based on a thorough analysis of all the tasks involved in the project. Ms. Pilko reviewed a few items in the process that could possibly be shortened and Ms. Pilko and Mr. COSTA MESA SANITARY DISTRICT ssAh 1 rqt MINUTES OF BOARD OF DIRECTORS SEWER SYSTEM COMMITTEE MEETING NOVEMBER 8, 2011 u �` PAGE 2 C Herberg stated they would attempt to achieve a quicker project completion for the OCSD Southwest Costa Mesa Trunk Sewer. The Committee thanked Mr. Herberg and Ms. Pilko for their attendance. NEW DISCUSSION ITEMS Mr. Hamers gave a report on required sewer lateral maintenance at 2740 Cardinal Drive and provided a letter sent to the property owner informing on the video inspection of the interior of the District's sewer main. The roots are protruding from the sewer lateral into the District's main to the point the roots have restricted the flow and caused a sewer spill on Cardinal Drive on September 27, 2011. The property owner was informed sanitary sewer overflows are a violation of both state and federal laws and subjects the District to fines. The property owner was informed the District has the right to charge for the emergency response clean-up costs for the event on September 27, 2011, however, the District will waive the costs if the property owner cooperates and removes the roots from the lateral. He was also informed the Residential Sewer Lateral Financial Assistance Program will fund 50% of the root removal costs up to $1,800. The property owner was informed the roots must be removed by November 14, 2011. The property owner at 2733 and other neighboring residents on Cardinal Drive were informed of roots located inside their laterals that are restricting flow and will soon likely block the flow from the laterals into the main, possibly causing a backup into their residences. The District strongly encouraged the owners to take preventative measures by removing the roots and to avoid flushing anything down the system other than bath tissue as products such as disposable wipes will catch on the roots and create a blockage. The owners were also informed of the District's Residential Sewer Lateral Financial Assistance Program. SEISMIC STUDY AND RETROFIT OF CMSD PUMPING STATIONS Mr. Carroll presented a report by Jerry Tucker and Associates, Inc. (JTA) on a Seismic Study of 14 Subterranean Waste Water Pumping Stations in Costa Mesa. The non- structural and structural repair of waste water pumping stations were summarized in priorities with implementation of priority I, II, III now and priority IV and V in the future. JTA will perform priority I study and CMSD Staff will work on priority II and III. The non- structural and structural repair of the WWPSs can be summarized in the following priorities: Priority I: Repair electrical control equipment enclosures and base connections at all WWPSs except #11 (Irvine Avenue) and #13 (23rd Street) to current 2010 CBC and ASCE 7-05 standards and to provide proper anchorage per section 13.3 of ASCE 7-05; repair rusted base and side walls as required; provide preventative measures to prevent future rust. Priority II: Provide secondary (backup) power to all WWPSs. Priority III: Provide flexible connections of all piping between and to and from all WWPSs. The solution to this recommendation is outside of the scope of this seismic study. A qualified registered mechanical engineer can provide the CMSD with recommendations regarding the proper connections. COSTA MESA SANITARY DISTRICT ��sanirgvr.. +5 �w MINUTES OF BOARD OF DIRECTORS SEWER SYSTEM COMMITTEE MEETING MY � NOVEMBER 8, 2011 PAGE 3 Priority IV: Provide additional structural support for all the WWPSs in liquefaction zones as shown in the report. Support can be accomplished by: A. Surrounding the perimeter of the wet and drywell (as one unit) with concrete grade beams; B. Providing concrete caissons at each corner with caissons embedded into bedrock. Priority V: Bond together all concrete entry rings with steel dowels and epoxy so that there is no movement between each element. Mr. Carroll stated Staff has requested Jerry Tucker and Associates to return with a proposal on proper anchoring the cabinets and Mr. Hamers is working on Priority III. Mr. Hamers stated the priorities are a good road map for seismic retrofitting. SOUTH COAST PLAZA RESTAURANTS Mr. Carroll reported on a meeting held on October 19, 2011 between South Coast Plaza, the Costa Mesa Sanitary District and EEC, to discuss dissolved sulfide levels and hydrogen sulfide odor issues stemming from the restaurants at the Plaza and the effect on the CMSD South Coast Plaza Pumping Station. A proposed sulfide study by EEC was provided. A proposed down drain for incoming line to reduce turbulence and sulfide release was discussed. A follow-up meeting will be scheduled after additional dissolved sulfide testing is completed and conclusions can be reached on the effectiveness of the additives. GIS ATLAS/CMMS/HYDRAULIC MODELING An oral report by Mr. Carroll was given on training for GIS Atlas and CMMS and there is a plan to place it on the District's server and EEC will also ensure the alignment of the District's lines is accurate. Mr. Hamers stressed the importance of using EEC with their extensive experience in these areas. PICA INSPECTION TECHNOLOGY Mr. Hamers gave an oral report on cleaning force mains (pigging) prior to electronic inspection. PICA has an electronic inspection tool that will reveal details of the pipe condition, however, the lines have to be cleaned using a "pig" prior to performing the electronic inspection. VICTORIA PUMPING STATION A report was given on a new traffic-rated door replacement by Nikola Corporation. The existing wet well doors were replaced with District supplied H-20 aluminum single leaf hatch door. ARTICLES OF INTEREST An article on Jefferson County sewer rates was presented, with officials saying the Birmingham City Council is being unrealistic in its fight against an increase in county sewer rates. Lawyers for the County Commission and sewer system creditors are working on an agreement, previously approved in concept, to settle the county's $3.14 billion sewer debt. The agreement could increase sewer rates as much as 8.2 percent a year for three years and no more than 3.25 percent a year afterward. The City Council unanimously approved a resolution denouncing any COSTA MESA SANITARY DISTRICT � MINUTES OF BOARD OF DIRECTORS SEWER SYSTEM COMMITTEE MEETING 's NOVEMBER 8, 2011 ..`. v421, .: PAGE 4 R?oca'ts` C plan to settle the county's multibillion-dollar sewer debt that includes rate increases, declaring the council would "fully investigate, explore and exhaust every legal means to protect the citizens of Birmingham from further, unaffordable, unjustified and excessive sewer rates." CMSD PROJECTS Project#101 West Side Pumping Station Abandonment Status Mr. Hamers, Mr. Herberg, and Ms. Pilko reported on OCSD's project timetable for their portion of the project, known as the Southwest Costa Mesa Trunk. Topographic mapping of Canyon Drive by the City of Costa Mesa was also discussed. Project#129 Bristol Street Sewer Phase ll Status Mr. Hamers reported a recommendation for award of construction contract will be given at the November 30, 2011 regular Board of Directors meeting. Project#171 Irvine Pumping Station Force Main Rehabilitation Status Mr. Hamers reported the District is finalizing plans and specs for bidding. Project#185 System-Wide Sewer Reconstruction Phase 1 of 4 Status Mr. Hamers reported construction continues on the project. Project#189 Rehabilitation of Six Sewers Transferred to CMSD Status Mr. Hamers reported construction is complete with Staff and the City of Costa Mesa monitoring South Coast Drive. Project#192 System-Wide Sewer Reconstruction Phase 2 Mr. Hamers reported the design phase is continuing. Project#193 Pumping Station Seismic Study Mr. Hamers reported the Consultant report is complete and Staff is implementing Priority I, II and Ill recommendations.
