Director Monahan called the meeting to order at 10:40 a.m. DIRECTORS PRESENT: Gary Monahan, Art Perry, Bob Ooten, Jim Ferryman STAFF PRESENT: Scott Carroll, General Manager, Thomas A. Fauth, Operations Manager; Sherry Kallab, Administrative Manager; Rob Hamers, District Engineer; Karl Dulake, Maintenance Supervisor; Debbie Bjornson, Permit Processor; Paul Guzman, Inspector OTHERS PRESENT: MONTHLY SSO STATISTICS Mr. Fauth reported no spills occurred since October 20, 2009. POTENTIAL PERFORMANCE INDICATORS FOR JUDGING AGENCY SPILLS A handout was provided in the Committee packet reviewing potential measures for identifying spills. Mr. Hamers reported once every three years there is a review of the Waste Discharge Requirements (WDR), both of the WDR itself and of the monitoring /reporting requirements. The monitor /reporting members make up the data review committee and the data review committee provided the potential performance indicators. The committee understands the number of spills per hundred miles is not the best indicator and has little correlation to the spill volumes. The information in the potential indicators is from actual data on spills and volumes of spills from January 2006 to January 2010 statewide. The committee is evaluating the data as a replacement to the spills per hundred miles indicator. Director Ooten noted at least ten people are looking at the same data sets to determine a good indicator. The data does show the significance of roots • at the facility. Mr. Hamers estimated the tri- annual review should be completed by July or August 2010. Mr. Hamers will schedule a follow -up inflow reduction meeting. psagrr�8 COSTA MESA SANITARY DISTRICT MINUTES OF BOARD OF DIRECTORS SEWER SYSTEM COMMITTEE MEETING '+1) APRIL 13, 2010 r .. �$➢' • ' —1�, PAGE 2 aaa's�5' SANTA MARGARITA WATER DISTRICT (SMWD) FORCE MAIN SPILL The Committee reviewed photographs taken of the Santa Margarita force main spill. Mr. Fauth reported a nearby creek was used as a containment vessel for the spill. The force main pipe was 24 inch. Lessons learned are forthcoming. The WDR Steering Committee is following up on the details. Mr. Hamers noted the pipe was only twenty years old which means something wasn't designed or inspected properly when installed; a ductile iron pipe (DIP) force main should not wear out in twenty years. If there is an error in installation, corrosion can cause damage very quickly. Santa Margarita did try to use other agency's pumper trucks, emergency response, personnel, etc. There were not enough assets in the area. At peak flow it was impossible for all the trucks to vacuum the spill - it was flowing so heavily and they had to keep pumping it into the creek to contain the spill. During low flow they were able to vacuum it out and drive it down to the other side of the force main and pump it into downstream manholes. Communication was also a problem in terms of when will the break be fixed, what is the spill volume, who do we contact, where do other agency's responders get gas, food and water. Mr. Hamers is not sure of the actual spill volume but has heard 900 thousand gallons. CMSD has an 18 inch force main that carries 3,850 gallons per minute so with a 24 inch force main it was probably between four and five thousand gallons per minute. It took days to find the problem and days to fix because it was on a slope and that kind of pipe had to be specially coated. Mr. Guzman reported on two significant CMSD spills in prior years and noted technology is not perfected to determine the condition of a force main pipe. 0 ASSET MANAGEMENT A seminar handout was provided in the Committee packet. Mr. Carroll and Mr. Fauth signed up to attend the April 21St and 22nd seminar. To piggyback on this workshop, Staff invited Brown & Caldwell to give a demonstration of their approach to asset management. Mr. Carroll noted Brown & Caldwell is a main player in asset management. Brown & Caldwell prepared the asset management plan study for the Orange County Water District, Irvine Ranch Water District, and Santa Margarita Water District. Staff will recommend an approach to the Committee. Director Ooten recommended Staff also talk to GHD. EAST BAY MUNICIPAL UTILITY DISTRICT ( EBMUD) PRIVATE LATERAL PROGRAM Mr. Fauth reported the EBMUD sewer lateral assistance program is going into effect. Mr. Hamers added they are under an EPA order due to poor sewer system management. The EPA order included private laterals. EBMUD's annual budget for the new program is $2 million per year. CMSD INFLOW REDUCTION PROGRAM The Inflow Reduction Subcommittee met on March 26, 2010 and the handout packet included a set of the meeting minutes. Director Ooten reported the Committee discussed sealing and plugging of manholes and an analysis of the data available to date. The District's efforts appear to have had an effect on OCSD's storm peak flow numbers - down significantly. Mr. Hamers is continuing to gather more data regarding rainfall and rainfall patterns. All Subcommittee members were assigned tasks and will meet one more time this season to set up the plan of • COSTA MESA SANITARY DISTRICT 5ANlfq MINUTES OF BOARD OF DIRECTORS SEWER SYSTEM COMMITTEE MEETING APRIL 13, 2010 'srP$ooeAt'�° PAGE 3 attack for the next rainy season. Mr. Hamers reported the WDR Inflow and Infiltration Surveys have been returned and data from those survey results will be available. CMSD MAP UPGRADES /GIS /CMMS UPDATES Mr. Fauth .informed the Committee the last portion of phase one will be complete once EEC receives the last few maps back from CMSD Staff. Staff authorized EEC to proceed to phase two. Mr. Fauth pointed out sections of the District with lines remaining to be cleaned to meet the three -year industry cleaning standard. Staff finalized the maps yesterday and meets with National Plant Services at 2:00 pm today to review. Mr. Fauth estimates it will take two months to complete the next 400 thousand linear feet using a three -man crew and two Vactor trucks. SCADA UPGRADE STATUS Mr. Fauth stated the project is for the most part complete. Staff worked with the City of Newport Beach personnel and arranged to have the trees around the 23rd Street pump station cleared to allow for the new antenna to be installed. The only station left to complete is the District Yard. Mr. Fauth has requested a copy of the relay plan from TRC. CMSD SEWER CLEANING /CCTV PROGRAM - UPDATE This item was discussed under CMSD Map Upgrades. WDR TRAINING SEMINAR 6 -17 -10 "TREE ROOTS IN SEWERS" Mr. Hamers reported the May seminar was delayed until June due to a conflict with another conference. The "Tree Roots In Sewer" seminar is now scheduled for June 17, 2010 from 9:30 till 11:30. CMSD PROJECTS: PROJECT #129 — BRISTOL STREET SEWER PROJECT Staff is currently meeting with contractors to determine the feasibility of pipe bursting the remaining one third of the sewer. PROJECT #171 — IRVINE PUMPING STATION FORCE MAIN Staff is meeting with lining and slip lining contractors to determine the best method to rehabilitate the line. The condition assessment is contained in a Staff report to the Board and will be in the next Board packet. Mr. Hamers recommended the Committee discuss the project more in depth after the Board has reviewed the report. a �e COSTA MESA SANITARY DISTRICT MINUTES OF BOARD OF DIRECTORS SEWER SYSTEM COMMITTEE MEETING , APRIL_ 13, 2010 l l`°QPa_ea'A° PAGE 4 PROJECT #186 — SEWER LATERAL ASSISTANCE PROGRAM Mr. Fauth reported $104,000 has been spent this fiscal year. Seventy eight projects have been completed, thirty eight are in process and one is waiting for review as of last week. The trend is cyclical and the reason is undetermined. Director Ooten requested Staff provide a multi -year report showing applications and completed projects.. PROJECT #187— DISTRICT YARD Mr. Hamers reported the District Yard project is progressing on schedule. Mr. Fauth reported the flag pole base installation is in process. A gas sleeve needs to be put in place. Staff chose to go with Mike Kilbride rather than the Gas company for a savings of $30,000. The contract for security services will be in the form of the CMSD standard contract and is currently under review with the company interface. Mr. Fauth reported bids were requested from four organizations and three were unresponsive. Mr. Hamers reported the City of Costa Mesa received stimulus funds plans to make street improvements on both the south and north side of Wilson Street. Staff eliminated from the contractor scope removing the old drive approach, building the new drive approach, new sidewalk and landscaping. Staff is working with the contractor to determine the savings to the District. The improvements are expected to be completed within the next two months. Mr. Carroll recommended waiting to hold the grand opening until the improvements are complete. Mr. Dulake reported the office furniture will not be delivered until June 1, 2010. Mr. • Fauth added the rebate for the solar panels is in process. CCTV VEHICLE DEMO The Committee attended a CCTV truck demonstration in the District Headquarters' parking lot. Mr. Carroll reported there will be discussion during the May 20, 2010 preliminary budget meeting regarding the purchase of a CCTV truck and other CCTV options. Director Ferryman asked if the District would need to hire an operator if the CCTV truck is purchased. Mr. Hamers responded most agencies use their own staff to operate the truck. Director Monahan requested Staff prepare an analysis of purchasing a CCTV truck or trailer or contracting for the service. Staff recommends a 10 -to -15 year interval for CCTV of the entire District sewer main lines. The CCTV truck, if purchased, would be for CCTV of small portions of the lines rather than entire line system. Director Monahan recommended bringing the analysis back to the Committee and after review, determine if a special meeting is needed to discuss the item. Mr. Hamers added when you go to the full CMMS sewer system management system Staff can take the data provided by the CCTV equipment and assign what was televised directly to the line segments creating a historical system management document. OTHER Staff reviewed a survey regarding illegal dumping of grease. District Staff did respond to the survey. The District has so little to report CMSD responses were not in the report. • SSC MEETING SCHEDULE The next meeting is scheduled for Tuesday, May 18, 2009 at 10:30 a.m � COSTA MESA SANITARY DISTRICT MINUTES OF BOARD OF DIRECTORS SEWER SYSTEM COMMITTEE MEETING APRIL 13, 2010 PAGE 5 • \ �POII PUBLIC COMMENTS There were no public comments.
