SCADA — UPDATE ON NEW RADIO SYSTEM AND REGULAR FIELD TESTING Mr. Hamers reported the District changed from cell phone to radio band width which is more reliable in an earthquake or major emergency. Regular testing of the new system has been implemented. Mr. Henson reported the crew has a pilot program where they match run time reports generated by the SCADA to manual run times calculated in the field, but only have a few days of data so far. Staff is receiving notification of high water and loss of power and is confident in the alarm portion of the system. Mr. Carroll has prescribed a regular testing of the alarm system.

ASANIt,,$ COSTA MESA SANITARY DISTRICT MINUTES OF BOARD OF DIRECTORS SEWER SYSTEM COMMITTEE MEETING FEBRUARY 15, 2011 OPoant�' PAGE 2 • PROPOSED REQUIREMENTS FOR MARKING GRAVITY SEWER MAINS AND LATERALS There is a move by drilling companies to require all sewer agencies to mark their gravity mains and sewer laterals to help prevent the boring through of those facilities. Current law exempts sewer mains, sewer laterals and storm drains. Most agencies are against changing the law due to the increased expense of marking the lines. Mr. Carroll stated if the Board wants to take a position it could be discussed with legislators at the upcoming Legislative Days. Mr. Carroll will follow up with California Association of Sanitary . Districts (CASA) regarding the legislation. President Ooten will follow up with Andy, Orange County Sanitation District (OCSD). The OCSD position is they don't own the laterals and don't know where the laterals are located. The legislation has not yet been proposed, but there is current lobbying to have it become a proposed law. Director Fitzpatrick questioned if the costs could be recovered from the contractors requesting the markings. Staff will continue to report on developments regarding the issue. SOUTHERN CALIFORNIA GAS COMPANY— RECONCILIATION OF SEWER LATERAL DAMAGE The Gas Company has come to Southern California agencies stating they started boring technology in the 1970s and know they bored through some sewer laterals. They are offering to find and repair those lines. • SOUTH COAST PLAZA PUMPING STATION INSTALLATION OF NEW PUMPS Three bids have been received. Mr. Hamers completed the reference check on the low bidder and will be recommending awarding the contract to the low bidder. Staff met with South Coast Plaza officials regarding odors at the station. Kevin, South Coast Plaza representative, has agreed to work with EEC and restaurant owners to keep sulfide levels down. Mr. Carroll noted the most important result of the meeting was acknowledgment the restaurants have to participate in order to resolve the odor issue. President Ooten is concerned by the over -sized grease interceptor installed on the property and the $15,000 per year the District is spending on chemicals for odor control. President Ooten added OCSD and IRWD have an ordinance regulating the amount of sulfides allowed to be discharged from the restaurants and noted CMSD may someday need to have an ordinance. Director Perry questioned the cost of a new interceptor. Mr. Hamers estimated the cost would be around $40,000. Director Fitzpatrick recommended the Committee look at IRWD and OCSD's ordinances in more depth and conduct a survey of other sewer agencies to see how many agencies have ordinances regulating sulfides. In the event an ordinance is needed Staff can work out an implementation period with a set compliance date for South Coast Plaza. Staff will be meeting again in a few months with South Coast Plaza, officials to review the results of their pilot program with one restaurant. If the results are favorable the program will be expanded. WDR REGIONAL MEETING -ROOTS WORKSHOP, 2 -17 -11 The workshop flyer was provided in the Committee packet. There will be an expert on trees and • a contractor, discussing their methods of mechanical and chemical removal of roots. Mr. Hamers will be attending and will report back. • • U COSTA MESA SANITARY DISTRICT MINUTES OF BOARD OF DIRECTORS SEWER SYSTEM COMMITTEE MEETING FEBRUARY 15, 2011 "I PAGE 3 EARTHQUAKE ASSESSMENT OF PUMPING STATIONS Mr. Carroll provided a quick update. A bid was sent out to obtain an assessment of the 14 District pump stations ability to withstand a 7.0 earthquake. Only one contractor responded to the request for bid, Jerry Tucker, a structural engineer. Mr. Tucker has the experience necessary. The bid amount was $29,400. Mr. Carroll submitted a letter of agreement, signed by Mr. Tucker. Mr. Carroll will be requesting a budget adjustment transferring funds from the contingency account at the upcoming Board meeting. If the Board approves the budget adjustment the work will begin in March with findings available in September. CMSD SSMP SELF AUDIT — PROPOSED CONSULTANT CONTRACT Mr. Hamers reported two speakers who have conducted self -audit made presentations at the WDR self -audit training seminar. WDR is also trying to contact South Pasadena or the Sacramento area sewer district to have them speak about the audits they have been through with the regional board and EPA. The seminar will include the enforcement people from the regional board. Mr. Carroll is considering a consultant for the CMSD's SSMP self -audit due by May 2, 2011. EDUCATION SEMINAR — INNOVATIONS IN SEWER MAINTENANCE, 3 -16 -11 A flyer was provided in the Committee packet regarding an upcoming webinar regarding best practices in sewer maintenance. Staff will be attending the webinar March 16, 2011. REGIONAL FOG SURVEY OCSD Staff conducted a survey of nine items considered fundamental to a successful FOG program. CMSD has all the components recommended. REGIONAL ADDITIVES SURVEY The results of a survey prepared by Carla Dillon, OCSD, regarding what agency's allow and use for grease, odor and insect control was provided. CMSD uses Golden Bell Insecta and sprays 300 to 500 manholes per year to remove the cockroaches. The product is environmentally safe. Many agencies use the product for roach control. Odor and corrosion products may or may not work, but the survey does help us understand what other agencies are using and provides us with more information. WDR TRIENNIAL REVIEW — ADOPTION BY SWRQB PRIOR TO 6/30/11 The review continues to be moved back but is supposed to be adopted by June 30, 2011. President Ooten questioned if an implementation period had been discussed. Mr. Hamers confirmed no implementation period has been discussed. Staff will continue to update the Committee about the review progress.

REHABILITATION Mr. Tsalyuk has contacted a number of pipe bursting and slip liner contractors. Under the Uniform Construction Cost Accounting method the District is required to notify contractors on our list. Staff contacted WR Rasik to give them the opportunity to provide a proposal for three different methods. Once all proposals are received Staff will review and present to the General Manager and the sewer sub - committee. RECENT % OF RAIN INGRESS INTO SEWER SYSTEM President Ooten requested some calculations on percentage of rain ingress. Mr. Hamers does believe the District has less than 2% rain ingress District wide. There may be small select areas where ingress could be over 2 %. Mr. Hamers believes OCSD uses some conservative values in their model for percent rain ingress. OCSD's model is showing 4 - 16% rain ingress. OCSD's consultant who conducted flow monitoring on the Dover trunk during rain storms found 0 to 20% ingress. President Ooten stated Staff has done an admirable job and it appears we are below the 2% goal set by OCSD. Director Fitzpatrick questioned if OCSD could assist in funding the effort. Mr. Hamers responded OCSD has provided funding in the past and Staff has requested OCSD update their numbers on how much inflow and infiltration is making it to the plant and what they would like the course of events to be. President Ooten clarified OCSD had codified the goal of • less than 2% ingress and the District is attempting to meet the goal. In addition, it is a WDR requirement by the state for agencies to mitigate inflow and infiltration.' Mr. Hamers estimates in the future the program will cost the District around $40,000. President Ooten noted the District does benefit by having less rain pumping through our pumping stations. ARTICLES OF INTEREST None provided this meeting. CMSD PROJECTS: Mr. Hamers reported Projects 129, 183 and 189 are in plan check. Project 189 -Rehab of Six Sewers Transferred to CMSD will be the first to go out for bid, then Project 129 Bristol Street Sewer Phase II followed by Project 183 - System Wide Sewer Reconstruction and finally Project 171 - Irvine Pump Station Force Main Rehab.
