Data continued to show zero SSOs have occurred in areas National Plant Services, Inc. (NPSI), has cleaned District main lines. TRC corrected previously encountered telemetry issues from select pump stations. Alternative telemetry backup options may still need to be explored with TRC including the feasibility of using land - lines. Staff will follow -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. I Ir1 • COSTA MESA SANITARY DISTRICT MINUTES OF BOARD OF DIRECTORS SEWER SYSTEM COMMITTEE MEETING a ! OCTOBER 10, 2007 t,a PAGE 3 lateral line issues. Mr Hamers plans to send a letter to Mr Allan Roeder to set up a meeting to discuss the issue with CMSD representatives and included the topic as an agenda item on the next Liaison Committee Meeting, scheduled for October 26, 2007. Staff met with C &R Drains to clarify the Sewer Lateral Assistance Program process as C &R Drains is a recommended contractor to perform lateral line cleaning, CCTV, cleanout.installation and lateral line repairs. POTENTIAL TRANSFER OF SEWER LINES FROM OCSD TO CMSD Staff noted there are 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: 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. More specific details are planned to be discussed at the Sewer Subcommittee meetings. 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 jurisdictions. 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) I►..J • - COSTA MESA SANITARY DISTRICT MINUTES OF BOARD OF DIRECTORS SEWER SYSTEM COMMITTEE MEETING _ OCTOBER 10, 2007 �. PAGE 5 MENDOZA GRAVITY LINE CONCEPT OVERVIEW Staff presented the implications of modifying the Mendoza PS to include an increased Storage capacity and gravity flow options in the event of a pump station failure. Discussions determined the risk of an SSO was too great to pursue this option due to the large area served, the slow flow rates, the frictions encountered for turns and blockages when compared to the depth of the lines and manholes and noting Mendoza PS currently has a 2 -hour retention time. The Subcommittee may further review the topic. 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, floor plans and site renderings 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 submitted the CUP to the City of Costa Mesa on October 3, 2007 and included plans to design a green facility (Leadership in Energy and Environmental Design, (LEED)) to Gold building standards. The District will evaluate green building costs versus non -green building costs, roughly estimated to be 8% for a LEED Gold construction. Directors plan to discuss the Yard with City officials.
