Public Utility District m
MEETING DATE: June 5, 2024
TO: Board of Directors
FROM: Brian Yohn, General Services Manager
Michael Salmon, Chief Financial Officer
SUBJECT: CARB Advanced Clean Fleet (ACF) Analysis
APPROVED BY:
Brian C. Wright, General Manager
RECOMMENDATION:
Receive this informational workshop and provide input to staff.
BACKGROUND:
Beginning January 1, 2024, the California Air Resources Board (CARB) Advance Clean
Fleet (ACF) regulation requires fleets that are well suited for electrification to reduce
emissions through purchase requirements for phase-in Zero-Emission Vehicles (ZEVs)
for targeted fleets. CARB approved ACF regulations on April 28, 2023, with an effective
date of October 1, 2023.
The ACF regulation applies to the District as a State and Local Government agency. It
requires the transition from all fuel-based vehicles with a gross vehicle weight rating
(GVWR) over 8,500 pounds to zero-emission vehicles (ZEVs) between 2024 and 2042,
with annual reporting due April 1 st each year, starting in 2024. The District currently
operates thirty-one (31) vehicles over 8,500 lbs. which are subject to CARB's ACF
regulations. Heavy-duty vehicles warranted for off-road use are necessary for the
District to perform the functions required to support utility operations.
In 2023, Truckee Donner PUD purchased two (2) 2024 Chevrolet Silverado EV light
duty work trucks to replace light duty vehicles scheduled and budgeted for
replacement. Staff will continue to identify and consider opportunities where ZEV
vehicle purchases can be feasibly made for future vehicle replacements.
Compliance pathways available to the District are the purchase compliance pathway
and the milestone compliance pathway.

purchase requirements until January 1, 2027. Beginning January 1, 2027, 100
percent of vehicle purchases are required to be zero-emissions if available.
• Milestones compliance option pathway: allows for phasing ZEVs into the fleet
between 2025 and 2042, depending on the type of vehicle and its usage.
To assist with fleet evaluation and long-term purchase strategies, staff contracted with
Yorke Engineering, LLC, to analyze and develop compliance strategies, including
timing of ZEV replacements, applicability of exemptions, and overall planning for ACF
compliance.
ANALYSIS AND BODY:
Considerations for ZEV vehicle purchases include:
• Vehicle intended uses
• Payload specifications
• Vehicle range
• Tow capacity
• Capacity to perform, and is warranted for, the functions required to meet the
District's needs?
• Vehicle availability
Availability of medium and heavy-duty vehicles that meet zero emission requirements
that can effectively perform the necessary functions to operate the District is currently
very limited, leading the District to the purchase pathway. Yorke Engineering, LLC
analysis supports following the purchase compliance pathway. The District will, unless
a competitive and feasible ZEV option is available, continue to purchase medium and
heavy-duty ICE vehicles before January 1, 2027, and seek exemptions when necessary
after that. This will position the District fleet with a late model bias, moving ZEV
purchase dates farther into the future.
This strategy provides the District with flexibility to implement ZEV vehicles into the fleet
when ZEV technology, vehicle availability, and market conditions improve. It also allows
the District to consider ZEV vehicle options available that best meet the needs of the
District.
The workshop item presented by staff will provide an overview of the District's current
fleet assets as well as short and long term strategies in achieving compliance with an
ACF rule making that creates a significant amount of uncertainty in terms of future fleet
procurement landscapes..
