EXCESS LIABILITY INSURANCE RENEWAL
1) Selection and Purchase of Excess Liability Insurance for July 1, 2022
Renewal Period
Staff had presented options for consideration at the Finance Committee and Board
meetings to renew excess liability insurance coverage for the upcoming July 1 renewal
period. These options included consideration to join a pooled liability program offered by
the California Sanitation Risk Management Authority (CSRMA), or to continue with
commercial insurance coverage pending receipt of insurance cost quotes by mid-June.
Delegation was provided to the General Manager to make the final selection of the
insurance coverage option based on cost and coverage. Staff considered each option in
full, including an assessment of coverage, claims handling and cost considerations, and
concluded continuing with the commercial coverage was the preferred choice at this time
and requested the insurance broker to proceed with the binding of coverage. The option to
consider joining a pooled liability authority will be revisited next year and remains a viable
option for future insurance coverage consideration.
Based on recent insurance coverage quotes received, the cost to renew with commercial
coverage was only a 10% premium increase from the prior year, less than the 30%
increase projected for the FY 2022-23 Budget. Even with a 10% premium increase from
the current premium level, the overall cost was less than the pooled authority cost
estimate received.
HUMAN RESOURCES
2) Central San Welcome New Maintenance Crew Member Louis Raffa
The Collection System Operations (CSO) Division welcomed its newest team member on
June 27, Maintenance Crew Member I, Louis Raffa. Louis joins Central San from EI
Sobrante Sewer Repair, a small family business. He has nine years of underground work
experience and the skills needed to keep a small business running. Louis shared he
wanted to work for Central San so that he can learn from the best and be a part of
something larger than himself. He lives in Richmond with his wife and two children. The
CSO team finds Louis to be a great fit to hit the ground running, and become a valuable
asset to the District.

OUT-OF-STATE TRAVEL
4) Staff Travel to Minneapolis/St. Paul, Minnesota and Green Bay, Wisconsin to
Tour Treatment Plants for the Solids Handing Facility Improvements- Phase
2 and Steam Renovations-Phase 1 Capital Improvement Projects
Central San Engineering and Operations and Maintenance staff are working on two
critical projects: Steam Renovations-Phase 1 and the Solids Handling Facility
Improvements-Phase 2. As a part of the Steam Renovations project, staff is evaluating a
Steam Turbine Generator. If Central San transitions to the new electric blowers as the
lead (currently, steam-driven blowers are lead), there will be a steam surplus. Rather than
waste this steam, installing a Steam Turbine Generator will assist in converting the steam
to electricity. Metropolitan Council Environmental Services (MCES) owns/operates seven
treatment facilities in the Minneapolis/St. Paul metro area and captures the heat from
sludge incinerators and produces electricity using waste heat boilers and steam
turbine/generators.
As a part of the Solids Handling-Phase 2 project, staff is reevaluating the selection and
phasing of biosolids facilities upgrades based on information and circumstances that have
changed since the last Comprehensive Wastewater Master Plan. The Green Bay
Metropolitan Sewerage District, operated under the brand name of NEW Water, collects
and treats wastewater. The solids handling treatment train includes anaerobic digestion
followed by solids drying and incineration. The digestion and incineration processes were
installed under the Resource Recovery and Electrical Energy Project and have been in
operation since 2018.
The following five Central San staff members will be visiting these two facilities to learn
about the benefits and challenges in operating these facilities from their Operations and
Engineering staff. The focus will be on treatment technologies and optimizations, and aim
to help best evaluate alternatives and develop new best practices for Central San.
Steve McDonald , Director of Operations
Jean-Marc Petit, Director of Engineering and Technical Services
Edgar Lopez, Capital Project Manager
Nate Hodges, Senior Engineer, Special Projects
Nitin Goel, Senior Engineer, Special Projects and Asset Management Group
Staff attendance to travel to these sites was included in the Fiscal Year 2022- 23 Capital
Improvement Budget to visit facilities with such operations that are mainly located in the
Midwest and east coast.

PROJECT UPDATES
5) Public Bidding of Pump Station Upgrades, Phase 2A, District Project 8457
The Pump Station Upgrades, Phase 2A, District Project 8457 (Project) will replace and
upgrade two pumping stations, Fairview and Maltby, in Martinez. These stations are used
to convey all the wastewater from the Martinez Pumping Station, which serves much of
the Martinez and Alhambra Valley service area. The Project is aimed to address
infrastructure needs, reliability, and improve safety. Construction will include, but is not
limited to, heavy civil, concrete, structural, underground piping, mechanical, new PG&E
services, electrical systems, emergency generators, instruments, controls, and other work
to build two 12.4 MGD (million gallons per day) peak capacity pumping stations. Once the
new stations are fully operational, the existing facilities will be decommissioned and
demolished.
This Project started advertising on June 30 and July 7, 2022. The bid opening is
tentatively scheduled for August 11, 2022. The Engineer's estimate for construction is
$35.4 million. More information will be presented when the Board is asked to award the
construction contract, scheduled for this September.
