3. Items for Committee Recommendation to Board
a. Review proposed Fiscal Year 2024-25 Capital Improvement Budget (CIB)
and Ten-year Capital Improvement Plan (CIP)
This item was heard immediately following Item 3.b.
Mr. Lopez provided an overview of the presentation included in the
agenda materials and responded to various questions from the
Committee.
Member Wedington inquired about the projects that are progressing but
not ranked high priority. A discussion ensued regarding how projects are
ranked and the prioritization process.
Mr. Lopez discussed in detail the Proposed FY 2024-25 CIB for the
Collection System, Treatment Plant, General Improvements, and
Recycled Water programs. He highlighted the estimated carry -forward in
the amount of $49 million.
In response to a question posed by Chair McGill regarding the CIB
contingency, Mr. Lopez confirmed that the $5 million contingency is kept
aside for various needs such as new projects, or emergency work.
Chair McGill asked whether the projects on Slide 5, Proposed FY 2024-25
CIB are included in the Ten -Year CIP. Mr. Lopez stated that none of the
active projects are beyond the Ten-year Budget. Mr. Norby added that
these are only active projects. Chair McGill requested that staff label Slide
5, Proposed FY 2024-25 CIB as active projects only.
Mr. Lopez continued with a summary of the major projects for the
Treatment Plant, General Improvements, Recycled Water and the
Collection System for the next Fiscal Year.
Mr. Lopez explained in more detail the major project Budgets which were
adjusted from FY 2023-24 to FY 2024-25 resulting in a total decrease of
$8.2 million in carryforward, not including closed project variances. Those
projects are included in the draft Budget and shown in the presentation
with the following:
• UV Disinfection Replacement total estimated budget was adjusted
from $7.98 million to $5.5 million.
• Solids Handling Facility Improvements Phase 2 was revised to $2.8
million.

• Steam Renovations, Phase 1 was adjusted from $8.5 million to $7
million.
• Orinda-Moraga Pumping Station Architectural Improvements was
revised to $450,000.
• Pumping Stations, Supervisory Control and Data Acquisition
(SCADA) and Programmable Logic Controller (PLC) Upgrades —
minor adjustment.
There was a discussion regarding the updated total project estimates that
were modified, highlighting the increases and decreases in the individual
project Budgets.
Mr. Lopez also discussed the proposed Ten -Year CIP FY 2024-34 in more
detail. He explained that each program includes a three percent
adjustment for future projects.
In response to a question posed by Chair McGill regarding Nutrients, Mr.
Norby stated that these numbers do not include the impact of the Nutrient
decision by the State Water Resources Control Board.
Mr. Leiber stated that the tentative order for Nutrient management came
out on April 6, 2024, and will be finalized on June 12, 2024. The
preliminary cost impact is estimated to be approximately $600 million to
the CIP numbers presented today.
The Committee had no further questions.
COMMITTEE ACTION: Recommended Board receipt.
b. Review draft Position Paper to authorize the General Manager to amend a
professional engineering services agreement up to $450,000 with HDR
Engineering, Inc., increasing the cost ceiling to $1,850,000 for additional
design services and Improvements under the Steam Renovations, Phase
1, District Project 100032
This item was heard as the first item of business.
Mr. Lopez provided an overview of the presentation included in the
agenda materials.
Mr. Hodges continued with the presentation providing the Committee with
background information regarding the project and identified the steam
system components that need to be replaced based on condition
assessments done over the last few years showing severe plugging.

In response to Chair McGill's question regarding items shown in red on
Slide 4, Page 16 of 23, Mr. Hodges advised that the critical items are
shown in red and present major potential safety issues for staff, if not
addressed.
Member Wedington asked what the timeframe was and whether this work
was included in the Budget. Mr. Lopez replied yes and explained that
some of the work has already been done in the Solids Conditioning
Building (SCB). He stated that the critical items in the SCB will be
coordinated with the Solids Handling, Phase 1A project and are included
in the Budget.
In response to Chair McGill's question regarding the condition of the
steam system, Mr. Goel explained that based on condition assessments
performed on the steam assets, most of the assets are still in acceptable
condition and have some useful life remaining. The discussion continued
regarding the additional design services and improvements needed for the
boiler feed water (BFW) system because of recent stress testing analysis,
as well as safety concerns.
Staff explained that the additional work required on the BFW system was
not related to condition assessment and based on updated codes for
design and safety reasons. In addition, the scope of the replacement
increased to a point where the work impacted operations and requires
more coordination and full replacement. The original scope was very
limited based on the condition assessment of the steam pumps, valves,
and some fittings.
Chair McGill expressed his concern about switching from steam driven
pumps to electrical pumps after the District has adopted a NetZero policy.
Mr. Goel explained that the steam -driven system is very complicated, and
the electrical system is simpler to operate and easier to maintain. Mr.
Lopez added that switching from steam to electricity was thoroughly
reviewed and evaluated, the change will increase reliability and will be an
overall benefit to the District and be more energy efficient. Central San
does not have plans to move away from steam and the system is
interconnected to electricity. Mr. Goel also added that switching from aged
steam -driven pumps to electrical pumps will also reduce the District's
greenhouse gas emissions.
In response to Member Wedington's question about the differences in
safety between using steam -driven pumps versus electrical pumps, Mr.
Goel stated that the concerns are significantly less using electrical pumps
as compared to the aged steam driven pumps.
