The first spill, from the Canyon pump station force main line, will be reviewed in detail in the following segment. The second spill occurred at the Irvine Pump Station on January 18, 2011 and was due to a clogged air release. The air release valve had been installed improperly. Approximately 10 gallons of water was released into the Santa Ana Delhi Channel. Mr. Hamers acknowledged the District was fortunate the volume of both spills was small. CANYON FORCE MAIN BREAK, 1 -8 -11 Mr. Hamers reported the Canyon force main spill was reported to Staff around 1:00pm on Saturday, January 8, 2011 and required emergency night response to repair the line. An • estimated 50 gallons was lost, but none of the spill was released to the waters of the State, the Greenville Banning Channel or the Pacific Ocean. Staff could not find evidence the spill made its way into Canyon Park, but in the event it did it would have been captured in the filtration marsh located in Canyon Park. COSTA MESA SANITARY DISTRICT MINUTES OF BOARD OF DIRECTORS SEWER SYSTEM COMMITTEE MEETING .JANUARY 25, 2011 c PAGE 2 • 1/1 REDUCTION PROGRAM The Committee reviewed rain data from the December 2010 storms. During the October 2010 rains the District had zero mpd into its pumping stations, as opposed to 2.69 mpd from the December 2010 rains. Mr. Guzman explained he had not been working during the November 18 to December 20th timeframe and many plugs and seals were missing when he inspected problem manholes. Mr. Hamers stated the program requires upkeep and additional money is needed in next year's budget to keep 1/1 low. Staff was directed to explore potential permanent solutions to plugging and sealing as part of next year's budget request. A letter written by Nick Arhontes, OCSD regarding the 1/1 problem acknowledged the District's success in reducing 1/1 and was provided in the Committee packet. SEWER CLEANING PROGRAM - AGREEMENT WITH NATIONAL PLANT SERVICES The year one cycle of sewer line cleaning was scheduled to start today but due to a slight delay will start next Tuesday. CMSD PUMPING STATIONS Mr. Hamers provided pictures of the Canyon pump station door replacement. Quarterly meetings are held with field personnel to review the needs of each pump station. Issues are round - tabled for solutions. The meetings have been very successful. Bids are being considered for the South Coast pump station and new pumps will be installed in the short term. ROOT CONTROL USING TOP HAT INSTALLATION The Committee viewed before and after pictures of six locations in the Top Hat Pilot Program. Four top hats and two short liners were installed at the sites. Staff will continue to monitor the installations for stability and root re- growth. Mr. Hamers thanked Mr. Carroll for developing the program. If the program proves to be successful Mr. Carroll will include funds in next year's budget for additional sites. CMSD SSMP AUDIT; MAY 2011; SEMINAR ON SELF AUDIT 1 -20 -11 @ CWEA EVENT, HUNTINGTON BEACH A City of Fullerton employee and a consultant for OCSD gave presentations at the January 20, 2011 WDR seminar regarding sewer system management plan (SSMP) audits. The audit looks at the agency's plan and compares to the actions of the agency to determine if the agency is in compliance with its plan. The agency can then take steps to improve performance as needed. The report will be presented to the Board of Directors. • • • • COSTA MESA SANITARY DISTRICT pSAH7tgd MINUTES OF BOARD OF DIRECTORS SEWER SYSTEM COMMITTEE MEETING JANUARY 25, 2011 ,$oosn PAGE 3 TRIENNIAL WDR REVIEW Mr. Hamers reported five changes anticipated in the triennial WDR for review: • SWRCB wants to require mandatory private lateral reporting. • Anyone with one mile of sewer must have their own WDR & SSMP • Shortened notification requirements • No required operator certification • Leave WDR as an order as opposed to requiring a NPDDS permit. Changes will also be made to add additional measures to more clearly reflect the performance of the system. The estimated final adoption date is May 21, 2011. WDR MEMBER AGENCY SURVEY Karla Dillon, OCSD, is conducting a survey to determine what chemicals are being used in kitchens, interceptors and for odor control in pumping stations. Once the survey is complete a spreadsheet of the results will be provided for the benefit of all. MERCURY IN SEWERS Mercury is on the radar screen along with other compounds. At this time mercury is a low percentage of the compounds they are concerned with. At this point in time there has been no recommendation to do anything about it. OCSD is not planning on adopting ordinances to prevent certain practices in dentist's offices; they are encouraging dental offices to buy the amalgam separator. There are potential legislative activates that could implement permanent measures and there are various sources of mercury in addition to the dentist office. OCSD is concerned with mercury because of the partnership with Orange County Water District (OCWD) requiring water be recycled to a drinking water standard. CMSD could draft an ordinance, resolution, or policy for prevention of mercury getting into the system through dentist office. At this point in time a separator would have to be installed on every chair in the dentist office to successfully remove all the mercury. Mark Kawamoto, OCSD, will be giving a presentation on the topic at the February or March WDR meeting. EARTHQUAKE ASSESSMENT OF PUMPING STATIONS Mr. Carroll submitted four RFQs to structural engineers. Jerry Tucker was the only engineer to respond with a proposal of $29,400 to assess 14 of the District's pump stations. Mr. Carroll reported the study was not budgeted but there is money available in the contingency to cover the costs. ARTICLES OF INTEREST One article was provided regarding 26 sewer spills totaling 8 million gallons into San Diego waters between December 21 and December 28, 2011. r 1 COSTA MESA SANITARY DISTRICT MINUTES OF BOARD OF DIRECTORS SEWER SYSTEM COMMITTEE MEETING ea JANUARY 25, 2011 :- `7a- // PAGE 4 CMSD PROJECTS: Mr. Hamers reported Projects 129, 183 and 189 are in plan check.
