Fauth, Assistant Manager; Joan Revak, Board Secretary/Program Manager /Clerk of the District; Karl Dulake, Maintenance Supervisor; Paul Guzman; Inspector; Joe Limon, Inspector; OTHERS PRESENT: None CMSD SANITARY SEWER OVERFLOW (SSO) STATISTICS, RISKS, LEVEL SENSOR UPGRADES AND MAINTENANCE UPDATE Mr. Fauth presented the overall SSO statistics for 2007 which added two spills from unknown blockages on September 4, 2007 — grease caused five SSOs, tree roots caused one SSO and Other issues such as debris blockage and a pump station bubbler failure caused four SSOs. Data shows zero SSOs have occurred in areas National Plant Services, Inc., (NPSI) has cleaned District main lines. Staff is reviewing alternative telemetry backup options with TRC including the feasibility of using land - lines. Staff is following up on Mr. Hamers' suggestion to research the possibility of TRC incorporating • a signal indicating a "COMMUNICATION ERROR" to first responders, if possible, especially for catastrophic failures. COSTA MESA SANITARY DISTRICT MINUTES OF BOARD OF DIRECTORS SEWER SYSTEM COMMITTEE MEETING + ; • 4_ �! SEPTEMBER 12, 2007 PAGE 2 Mr. Fauth presented a revised "Prioritized Pump Station Retention Times" chart identifying the criticality and hours of wastewater retention per PS and the highest risk pump station (PS) concerns including options to back -up and replace PS bubbler systems. The revisions added the identification of PS wastewater level sensors and the planned PS upgrades. Canyon PS remained the most critical with a one -hour retention time and 21St St PS is the least critical with a 10 -hour retention time. Staff added the following to the "Hotspot" list: 1. 722 W 16th St location and scheduled National Plant Systems Inc., to CCTV the CMSD main line. 2. 1599 Superior Ave location as this is a repeat location for an SSO from May 28, 2007. Staff set a budget of $12,000.00 for JIMNI Systems to upgrade Victoria PS, Harbor PS and South Coast Drive PS from a wastewater level sensor consisting of a only a bubbler system to a combination Pressure Sensor with Float Switch backup. JIMNI Systems agreed to upgrade the three PSs for the budgeted cost to increase PS reliability. Staff will re- categorize the factors in the "CMSD Pump Station Risk Analysis" chart and • place them objectively on the chart. Staff will research Director Ooten's suggestion to employ a thermography (Infrared Thermal Imaging) technique to detect heat in control panels. Staff will follow -up on Mr. Guzman's recommendation to identify PSs with and without surge protection. SEWER LATERAL ASSISTANCE PROGRAM AND SURGE FLYERS The Committee reviewed the program status noting the press release, website advertisement, new ordinance and program kickoff parameters. Mr. Hamers previously presented the program to the Waste Discharge Requirements (WDR) Steering Committee and received mostly favorable acceptances. Several residents have called requesting sewer lateral assistance applications. The application states "CMSD will contribute 50% of the residents' costs up to a maximum of $1,800 ". The purpose is to encourage residents to maintain (clean and CCTV) their laterals on a regular basis to achieve zero SSOs. Staff included the Lateral Assistance program in the 5 -Year Capital Improvement Program for FY 2007 -08 Through FY 2011 -12 at a level $100,000 per FY. The District plans to distribute the "Sewer Lateral "Surge "" flyer to facilities with a history of experiencing or potentially experiencing a surge during CMSD main line cleaning. POTENTIAL TRANSFER OF SEWER LINES FROM OCSD TO CMSD • Staff reviewed and evaluated eight potential sewer line transfers from OCSD to CMSD. Before acceptance, OCSD would need to clean and CCTV the lines and rehabilitate any deficiencies. Staff arrived at the following summary status: C7 • COSTA MESA SANITARY DISTRICT MINUTES OF BOARD OF DIRECTORS SEWER SYSTEM COMMITTEE MEETING i SEPTEMBER 12, 2007 k t, PAGE 3 1. APPROVED: Avenue of the Arts (S -192); Anton to Sunflower; Built in 1987; Sewer line is in acceptable condition; Six MHs need to be reconditioned; Staff needs to calculate the expected revenue CMSD will collect for the line; 2. APPROVED: Park Center Drive and Anton Blvd. from the West (S -192); Built in 1967; Sewer line is in acceptable condition; Northernmost MH needs to be located and raised; 12" line; 3. APPROVED: Bear Street, in front of Crystal Court — the western line only (S- 193); Sewer line is in acceptable condition; 15" line; 4. APPROVED: Smalley Road trunk line (S -194); Sewer line is in acceptable condition; One MH in the middle of the park needs repair; 15" line on San Leandro Lane; 5. APPROVED: LA Times and South Coast Drive (S -196); Sewer line is in acceptable condition; Need to clarify how IKEA connects to the main line; 12" line; 6. NOT APPROVED: Pullman St (S -165A and S- 165C); Sewer line is in acceptable condition; Needs MH cover repairs and a MH relocation; only two CMSD connections. 7. UNDER EVALUATION: Pine Creek and Adams (S -181 and S -180); Sewer line is in acceptable condition; 18" line; 8. NOT APPROVED: Pomona Ave (S -152); Sewer line is in acceptable condition; Line is a cut - through only; 18" line; no CMSD connections. The transfers would effectively transfer these lines from a regional large diameter pipe agency to a local agency. A regional agency generally owns and maintains sewer lines with large diameters (greater than 30 inches) that serve two or more jursidictions. Local agencies generally transport sewage in smaller lines to these trunk lines and the lines under consideration meet the test as local sewers. Following cleaning, CCTV and any required rehabilitation, the transfers result in additional revenue for CMSD at little cost for CMSD to maintain the lines. Many locations have Food Service Establishments (FSEs) and require Fats Oils and Grease (FOG) management within the CMSD. If the lines are not transferred, there will be confusion between OCSD and CMSD as to FOG management. Staff will follow -up on Director Ooten's recommendation to notify the site owners of the transfers while the transfer documentation is in development. Mr. Hamers presented the topic to the Board at the August 9, 2007 CMSD Regular Board Meeting. FOG PROGRAM The WDR Steering Committee arranged for various agencies to have Orange County Health Care Agency ( OCHCA) inspect the Food Service Establishments for compliance with the FOG program once per year during their three yearly site visits. During one of • the annual visits, the OCHCA inspector will inspect specifically for BMPs and FOG compliance. Each FOG inspection takes up to 20 minutes and costs CMSD of COSTA MESA SANITARY DISTRICT MINUTES OF BOARD OF DIRECTORS SEWER SYSTEM COMMITTEE MEETING SEPTEMBER 12, 2007 PAGE 4 approximately $20. EEC is coordinating inspections schedules and reporting with OCHCA. OCSD has implemented a successful residential FOG control program. CMSD could adopt this approach after the FSE SSO plans are fully implemented. DISTRICT YARD UPDATE CMSD entered a 90 -day escrow for the two vacant parcels at 174 West Wilson Street on August 31, 2007 for a total cash purchase price of $900,000.00 including a $75,000.00 deposit into escrow. The Phase I Environmental Site Assessment (ESA) Report, dated September 26, 2006, documents the site is clean of hazardous waste chemicals - Non - Detectible (ND). Mr. Fauth presented the draft architectural site and floor plans from Mr. Bob Thornton of RTA, Inc., the site architect. The site is envisioned as having a 5,116 SF building on an 18,200 SF lot. Staff will follow -up on Director Ooten's recommendation to identify additional "District -owned Yard" cost savings such as fuel savings from contractor co- located equipment parking and document storage savings from the current storage facility. CMSD plans to design a green facility to Leadership in Energy and Environmental Design (LEED) Gold building standards and submit the Conditional Use . Permit (CUP) package to the City of Costa Mesa in early October. The District will evaluate green building costs versus non -green building costs, roughly estimated to be 8% for a LEED Gold construction. CMSD PROJECT #101 — WESTSIDE PUMP STATION ABANDONMENT The Committee supported sending a letter to OCSD to formally propose the project in the OCSD budget, estimated to occur in the FY2012 -2013 timeframe. Mr. Hamers is completing the projected CMSD costs. The two options OCSD costed are as follows: 1. Option 1: $9.0 M for a gravity flow system, or 2. Option 2: $6.6 M to rebuild the City of Newport Beach Pump Station and the force main.
