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
grease blockages on October 5 and 6, 2007 — grease caused seven SSOs, tree roots
caused one SSO and Other issues such as debris blockage and a pump station bubbler
failure caused four SSOs. 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.

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)

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.
