ISSUE
The Board of Directors (Board) approval of the Ultraviolet (UV) Disinfection Replacement Project, District
Project 100012 (UV Project) is required prior to the filing of a Notice of Exemption under the CEQA
Guidelines and submit an application to qualify for funding eligibilityfrom the SRF.

BACKGROUND
Central San has been successful in competing for SRF loans with the completed execution of a$173.1
million agreement in 2021 for the Solids Handling Facility Improvement Project. Loan terms provide 0.9
percent financing for 30 years with debt service starting one year after construction is completed. Central
San submitted an application in December 2018 and was selected to receive funding through this
competitive process, administered by the SWRCB. There is a strict point system for the award of SRF
loans and SW RCB values projects that will either correct or prevent Water Quality Control Plan or Permit
violations.Additionally, two of the sixteen total points available are for project readiness.Applications are
due by December 31 each year for the award in the following fiscal year.
The UV Project will replace the aging UV disinfection system at Central San. Most of the existing UV
system has been in service for 26 years and requires substantial maintenance, lamp replacement, and
frequent chemical cleaning of UV banks. The UV disinfection system is mainly electrical and electronic-
based equipment, most of which has outdated components and technologies. The power of the existing
UV lamps cannot be modulated and leads to frequent lamp replacements. For wet weather operation, the
UV system only has a capacity of between approximately 90 to 100 million gallons per day(MGD), and it
has been established through hydraulic modeling that a capacity of 127 MGD is needed in wet weather.
This creates a hydraulic bottleneck in the secondary treatment plant, limiting the discharge of disinfected
final effluent during the peak of wet weather events. Staff believes this project scope will score well for the
SRF loan process.
The UV Project evaluated alternative state-of-the-art disinfection technologies such as LED UV, ozone,
peracetic acid, and sodium hypochlorite disinfection to determine the optimal disinfection system for
Central San. Based on a comprehensive evaluation, continuing with UV disinfection technology was
determined as the best path forward. The location of the project area is shown in Attachment 1. Siting the
new 127 MGD UV disinfection system adjacent to the south clarifiers provides multiple benefits. First, it
frees the existing UV areas for future secondary capacity needs that may arise due to future potential
nutrient regulations. Second, it alleviates the existing hydraulic bottleneck in the secondary treatment plant,
which currently limits the discharge of disinfected final effluent during the peak of wet weather events. The
final design will be based around the equipment manufacturer selected in December 2022, included as a
concurrent approval on this agenda. Final design will start in early 2023, with completion by mid-2024. If
this project is not selected for an SRF loan in 2023, there is still time to resubmit for the following year.
Construction would start after the SW RCB project review process is completed and a loan agreement is
executed, likely in 2025.
This approval does not include the award of a construction contract. Such an approval will be considered at
a later time once project bidding has been completed. Meanwhile, staff would proceed with an application
for funding eligibility with the SRF, which offers low-cost financing for a wide variety of water quality
projects. Completing the CEQA compliance process at this time with the filing of a Notice of Exemption
(Attachment 2)would improve Central San's funding eligibility.
The SRF funding application requires the inclusion of certain Board resolutions related to the financing
and authorization to submit an SRF application (Attachment 3).Another resolution pledges revenues and
funds to support the repayment of the SRF loan (Attachment 4). The resolution has been reviewed by
District Counsel.
CEQA
Staff has concluded that this project is exempt from CEQA under Central San's CEQA Guidelines
Section 15302 since it involves the replacement of existing public facilities at substantially the same
location and with the same purpose as the public facilities being replaced. The projects are also exempt
under Central San's CEQA Guidelines Section 15061(b)(3) since it can be seen with certainty that there is
no possibility that the activity in question may have a significant effect on the environment. This certainty is
based on Central San's past experience with the construction of numerous treatment plant improvement

projects of this nature, its long familiarity with the project site, Central San's impact-limiting construction
specifications, and the impact-limiting components of the project description. Central San's specifications
are standardized general and special conditions that are made part of the project to address environmental
considerations, as well as compliance with applicable federal, state, county, district, municipal and local
laws, ordinances, orders, and regulations.Approval of this project will establish the Board's independent
finding that this project is exempt from CEQA.
ALTERNATIVES/CONSIDERATIONS
The Board may delay or decline to approve the UV Project. This project involves a critical step in the
treatment process (disinfection), which is needed to achieve permit compliance and needs to be reliable.
This alternative would impact future replacement of the UV system and would likely increase the overall
cost to Central San with more maintenance and potential risk with deteriorated equipment.Additionally, the
project could miss the chance to be eligible for SRF funding and other Community Project funding
opportunities. The CEQA process must be completed for funding eligibility from the SRF.
Alternative funding sources are also possible for the UV Project, including funding directly through Central
San rate revenues or through the issuance of revenue bonds instead of SRF loans. Neither is optimal.
Funding directly from rate revenues would (1) require rate increases beyond the levels previously
conveyed to the Board in Central San's financial plan; and (2) not optimally balance the funding of a long-
lived asset with the asset's useful life, in addition to raising concerns about intergenerational equity.
Funding the UV Project in part with revenue bond proceeds is the baseline expectation in Central San's
financial plan; however, SRF loans carry interest costs at roughly one-half the anticipated cost of revenue
bonds. SRF loans are optimal, if available, and Central San has strong incentives to compete for such
funding, which the adoption of the resolutions associated with this position paper will permit.
FINANCIAL IMPACTS
This Position Paper only approves the project for CEQA and funding eligibility request purposes. It does
not award a construction contract. SRF funding eligibility could ultimately benefit Central San financially to
a significant degree despite some up-front and ongoing costs.
Costs to prepare a SRF application for the UV Project are estimated at up to $30,000 for staff time.
These up-front costs and other SRF associated project costs are significantly below the potential long-
term savings from the reduced SRF interest rate when compared to that of revenue bonds. As of October
2022, interest and other costs over the assumed 30 year term are significantly lower in an SRF issuance at
34 percent of the borrowed amount versus 63 percent of the borrowed amount for Revenue Bonds based
on reasonable assumptions for the projected all-in cost of revenue bonds versus SRF loans. Comparing
the present value of total interest and principal payments of an SRF loan versus a revenue bond shows
savings of$18.7 million for SRF. This represents savings of 29 percent of the maximum borrowed amount
assuming revenue bonds (project cost and costs of issuance of$65 million). These significant savings
exist even assuming the following estimated incremental costs with SRF funding versus revenue bonds:
• Additional staff and consultant costs to apply for and comply with SRF loan requirements of an
additional $100,000 above those of a Revenue Bond issuance.
• Potentially higher bid costs for Davis Bacon and Buy-American material requirements, assumed at
three percent of the presently assumed cost of the project.
COMMITTEE RECOMMENDATION
