CMSD SEWER SPILL STATISTICS AND MAINTENANCE UPDATE
Following a review of the minutes from the May 23, 2007 Sewer System Risk
Assessment Subcommittee Meeting, Mr. Fauth presented the overall Sanitary Sewer
Overflow (SSO) statistics for 2007 — grease caused four SSOs, tree roots caused one
SSO and Other issues such as debris blockage and a pump station bubbler failure
caused two SSOs. Discussion centered on pump station and line cleaning maintenance,
plans and records Staff maintained since January 2006 since changing to National Plant
Systems, Inc. (NPSI) and JIMNI Systems for maintenance. Of note, zero SSOs have
occurred in areas NPSI have cleaned District main lines. Staff confirmed hot spot
cleaning has managed to prevent repeat SSOs at the same locations. The District
extended the CCTV schedule to July 2008 instead of doubling up the CCTV and
cleaning crews. Staff continues to evaluate options to back -up or potentially replace
pump station bubbler systems.

Staff presented Risk Analysis Primer including a fishbone analysis technique for
evaluating pump station failure risk. These results will next be evaluated and plotted
using a classic Risk - Frequency Analysis technique. Mr. Dulake provided a summary of
pump station status for all 20 District pump stations, which directly support the fishbone.
analysis. CMSD must rent a hoist truck to remove and maintain the largest pumps at
Irvine, Elden and Harbor as the weight is above the capacity of the District service truck.
CMSD PROJECT #101 — WESTSIDE PUMP STATION ABANDONMENT
Staff presented the OCSD "Rough Order of Magnitude Estimate" covering the projected
decreasing OCSD budget trend from $353M in FY 08 -09 to $24M in FY16 -17. Director
Ferryman confirmed FY12 -13 is the soonest OCSD can add the cost to the budget to
fund the CMSD Westside Abandonment. Director Ooten noted the OCSD budget
process begins in September of each year. The two options OCSD costed are as
follows:
1. Option 2: $9M for a gravity flow approach.
2. Option 2: $6.6M to rebuild the City of Newport Beach Pump Station.
Mr. Hamers presented a map depicting the completed CMSD lines (Southern A6, A3 and
Al) and District plans to cost out the engineering /construction costs for CMSD's portion
of the cost including $250K/FY in the Capital Improvement Projects (CIP). Director
Monahan recommended adding a Consumer Price Index (CPI) inflationary factor to the
CIP budget each year. Mr Hamers will send a letter to OCSD documenting CMSD's
estimated cost within the next two months.
CMSD CLEANING CREWS
Discussions re- verified the District sewer maintenance plan consists of the following
approach through June 2008:
1. NPSI will provide maintenance cleaning of one -half of the CMSD main lines every
year after the current televising project is complete.
2. NPSI will provide hotspot cleaning on Friday every week.
3. JIMNI Systems will provide the primary maintenance on the 20 District pump
stations.
4. C &R Drains remains as the CMSD after -hours emergency first - responder.
Staff analysis documented the cost of a comparable in -house crew and equipment to
perform hot spot cleaning and first responder services is approximately 2/3 the cost of a
contractor, using fully- burdened data. Staff will document the savings comparing NPSI
costs to the costs for in -house operations.

SEWER LATERAL ISSUES
Mr Hamers presented the memo on "Common Sewer Laterals ", noting CMSD
ordinances allow common laterals for condominiums, but for condominium conversions,
owners must CCTV their lines. Director Monahan recommended Mr Hamers write a letter
to the City of Costa Mesa regarding the CMSD approach to require CCTV services for
condominium conversions. Discussion covered several options for triggers requiring
CCTV of lateral lines. Mr Hamers and Staff will document a comprehensive approach to
identifying when CCTV services are required and the conditions for changing common
sewer laterals to single laterals. Potential triggers include an SSO, an inside facility
backup, a repeat SSO and remodeling thresholds.
Staff included the Lateral Assistance program in the 5 -Year Capital Improvement
Program for FY 2007 -08 Through FY 2011 -12 at a level $100,000.00 per FY.
CMSD EMERGENCY RESPONSE - DISTRICT YARD UPDATE
Staff is coordinating meetings with City of Costa Mesa representatives to reach an
• agreement on suitable locations for a CMSD yard within the City of Costa Mesa. The
minimum District Yard requirements to respond to SSO emergencies remain as follows:
a. Location: Centralized District location for equalized response;
b. Lot Size: 9,000 to 12,000 sq ft for outside storage and parking;
c. Building Size: 2,500 to 5,000 sq ft for office, hoist repairs and storage;
Siting issues include the availability of property, the property zoning (MG needed), the
City of Costa Mesa requirement for conditional use permits (CUPS requiring 10 -12 weeks
to obtain approval) and the four zoning overlays in place. The overlays are:
1. South of Bristol Entertainment, Culture and Arts Urban Plan (SoBECA);
2. Mesa West Bluffs Urban Plan;
3. 19 West Urban Plan; and
4. Mesa West Residential Ownership Urban Plan.
Mr Fauth will contact Mr Don Lamm, City of Costa Mesa Development Services Director
to pursue flexibility in obtaining a yard in the City of Costa Mesa. The primary example of
the issue is the inability of CMSD to acquire the property at 2973 Randolph Ave, Costa
Mesa, CA with attractive terms including an all cash purchase and close of escrow in 30
days.
