MONTHLY SSO STATISTICS
Mr. Fauth presented the Sanitary Sewer Overflow (SSO) statistics for 2008 noting no
new additions since September 4, 2008. Mr. Fauth reported there were two private
controlled clean outs. One clean out was located at Vanguard University and was
needed due to a float problem in their private pump station. Director Ferryman asked if
the District was required to report the spill. Mr. Fauth clarified the spill did not meet any
of the three'reporting requirements; it did not enter the public right of way, it did not enter
the storm drain and was not over 1000 gallons.
COMPLIANCE WITH WASTE DISCHARGE REQUIREMENTS
Mr. Fauth noted the WDR Steering Committee SSO Compliance Status Report is
• available for review. Mr. Fauth pointed out non - compliant jurisdictions are highlighted in
red on the spreadsheets and CMSD is not one of them. CMSD is in full compliance with
all three reporting requirements.

HYDRO - MECHANICAL GREASE INTERCEPTORS (BIG DIPPER)
Mr. Fauth referred to photographs in the Committee handout. There are two sets of
photographs. The first set of photographs shows the installation of the Big Dipper under
the counter. The second set of photographs shows installation of the Big Dipper in a
private room. The Big Dipper is good for a small "mom and pop" type restaurant so they
do not have to set up a gravity interceptor. Director Ferryman asked if the Big Dipper
has a limited capacity compared to a gravity interceptor. Mr. Hamers confirmed it does
have a limited capacity. Mr. Hamers discussed the fact the Orange County Health Care
Agency does not currently approve under the counter installation of the Big Dipper. The
WDR Steering Committee is working with the Orange County Health Agency to have
their bulletin of rules and regulations revised. Ralph Palomares, WDR Steering
Committee, is giving six -to -seven tours of facilities using the Big Dipper within the El
Toro Water District to the Agency. Currently, the Agency is attending WDR Steering
Committee meetings. Mr. Hamers expects a quick resolution regarding the issue.
The Committee discussed an e-mail from John Schafer regarding a meeting he attended
representing Orange County, including the District, where he promoted the status quo of
what exists in the plumbing regulations on sizing of grease interceptors. The vote was
200 to 4 in favor of retaining the current regulations. There was a move to increase the
size of the grease interceptors. Mr. Hamers reported almost every restaurant has an
incoming 4" pipeline. A 4000 gallon interceptor was being required for a 4" pipeline. Mr.
Hamers advised a 4000 gallon interceptor is too large and would generate too much
hydrogen sulfide, increasing severe odors. In addition, when air mixes with the hydrogen
sulfide it becomes sulfuric acid and will eat away the concrete in manholes. The District
is happy with the outcome of the vote to maintain the current regulations.
RESIDENTIAL FOR - DUDEK PRIVATE SEWER SPILL CONTROL
MEASURES STUDY - EXECUTIVE SUMMARY
Mr. Fauth highlighted the results of the Dudek study. The study identified multi - family
residents as the primary threat of private sewer lateral spills and the primary cause of the
spills was grease. The study found public sewer spills have declined and private sewer
spills have increased. Nine best management practices were developed and CCTV of a
private sewer lateral within a specified number of days after an overflow was the most
effective recommendation. The District wants to be pro - active in preventing private
sewer spills from occurring and plans to start implementing some of the best
management practices recommended in the study. The District expanded the existing
FOG program to include six to twenty unit multi - family complexes. Staff met with the
District's FOG consultant, Jim Kolk, to discuss implementation of a multi - family program.
Mr. Kolk will check with the City of Costa Mesa regarding information available in their
database to help identify complexes of the size identified in the Dudek study.

VAPOROOTER RESULTS
Staff noted the Committee reviewed videos showing positive results of the Vaporooter
product used at two locations during the previous Committee meeting. Staff proposed to
make a second .set of studies at the locations of Clubhouse Drive and Carnegie Drive.
Mr. Dulake met with the Vaporooter representative regarding the above locations. The
representative is a little reluctant to perform additional free tests. In addition, his crew is
not currently in the Orange County area. Mr. Hamers added Vaporooter had requested
a letter of recommendation from the District and the District would like additional proof
before making those recommendations. Mr. Dulake will follow -up on an additional test of
the product.
REVIEW OF ENHANCED MAINTENANCE AREAS
Mr. Fauth announced the hotspot repair at Victoria & Harbor is complete. The next hot
spot to be repaired is located at Fair & Harbor. Mr. Dulake commented he spoke to
Sancon, the project contractor, this morning and it will take two to three weeks to deliver
the job materials. Once the materials have arrived, Sancon will call to arrange a
schedule for the job. Mr. Hamers reported Sancon will chain -fling the inside of the pipe
® then re -line it. Mr. Fauth reminded the Committee as per the July 17, 2008 WDR
Seminar, hot spots are now considered enhanced maintenance areas. Director Ooten
requested Staff to contact Jim Kolk to update his list and have it available for next
month's Committee meeting.
TRANSFER OF SEWER LINES FROM OCSD TO CMSD
Mr. Hamers presented a draft letter to parcel owners who will incur an increase in
charges due to the transfer of sewer lines from OCSD to CMSD. Staff also provided an
updated worksheet Ms. Bjornson prepared regarding the amount of the increase in
charges. Staff is waiting for a response from OCSD regarding changes requested in
certain lines of the agreement.
FORCE MAIN CORROSION
Mr. Hamers announced the WDR Seminar November 20, 2008, "Life Expectancy of
Force Mains" will cover cast -iron and ductile iron pipe. V &A Engineering will present the
results. The District is working with V &A Engineering to prepare an evaluation proposal.
CONSTRUCTION /MAINTENANCE ACTIVITIES
Mr. Fauth reviewed the first spreadsheet provided, dated September 9, 2008, noting no
changes since the last meeting. The second sheet with a listing of the twenty pump
stations shows everything green on the front page with two left to convert from bubbler to
pressure system on the back side of the sheet. The next chart covered pump station risk

analysis. Everything in green blocks is an update based upon replacement of the
bubblers to pressure sensors to reduce risk. The risk for replacement increased due to
the loss of the spare equipment not yet replaced. The frequency of problems is
decreasing but the risk of something occurring is at the same level or higher. Loss of
communication has decreased in risk. Cable connections and water seals have been
replaced at the same time as the bubbler sensors. The backup system has dropped
from the upper quadrant to the left hand quadrant because of all of the above. The
analysis is subjective but based on objective data.
OCSD PEROXIDE STATION AT CMSD MENDOZA PUMPING STATION
Staff provided pictures to the Committee showing the CMSD pump station control panel,
containment of the two 3000 gallon tanks and the control setup within the aluminum wall.
Also shown is the rubberized bladder within the containment to take care of a spill should
one occur. Mr. Hamers voiced concern about rain and ponding in the container. Mr.
Dulake replied the concern has been mentioned to Brian Reed with OCSD. Mr. Fauth
was directed to send an e-mail to Brian regarding how OCSD plans to address the issue
of storm or rain water ponding inside their secondary container. Mr. Dulake noted the
fencing will need to be addressed in the event the pilot project becomes permanent.

PROJECT #175 OCSD GRANT - TELEVISING CMSD SEWER LINES
Staff reported televising is 90.6% complete (1,023,490LF/1,129,420LF).with an
estimated project completion date of June 2009. Mr. Fauth advised there is a
discrepancy between the District and National Plant Services regarding the total linear
feet. Dennis reported 1,024,000 total linear feet which would mean the job is 99.8%
complete. The job is not 99.8% complete. Mr. Fauth is checking with Dennis regarding
the basis of his total linear feet number. Mr. Fauth noted 26,500 linear feet was
completed last month. If the rate of completion remains the same the project would be
completed by January 2009. Mr. Dulake voiced concern with the January completion
date due to the condition of the big lines left to clean. Mr. Hamers requested Mr. Dulake
report back with the depth of flow after the 12" lines are cleaned.
