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.

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:

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

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.
