Department: Administration
Cost Center: 1002
For Agenda of: 1/20/2026
Placement: Business
Estimated Time: 20 Minutes
FROM: Whitney McDonald, City Manager
Prepared By: Natalie Harnett, Policy and Project Manager
SUBJECT: CONSIDER INVITATION TO JOIN LETTER FROM THE COUNTY OF SAN
LUIS OBISPO REQUESTING STATE LEGISLATION RELATED TO
DIABLO CANYON POWER PLANT
RECOMMENDATION
Receive the County of San Luis Obispo’s invitation to join a request for State legislation
related to the Diablo Canyon Power Plant and provide direction to staff regarding
participation in the letter drafted by the County.
POLICY CONTEXT
The City Council annually adopts a Legislative Action Platform (“Legislative Platform”)
that establishes the City’s positions on legislative matters of importance . It does not
extend to advocacy for or against any individual project, program, or entitlement
application unless specifically noted. In this case, the City has received a request to join
in efforts to seek legislative support on a part of an issue not included in the current
Legislative Platform, and the matter is therefore being presented to the Council for
direction.
DISCUSSION
On Monday, December 22, 2025, the City Manager received an email from the County of
San Luis Obispo’s (“County”) Assistant Executive Officer, following direction from the
County Board of Supervisors provided as part of an item added to the consent agenda
during its meeting held on December 16, 2025. The email included a County-led draft
legislative letter (Attachment A) requesting State legislation related to the continued
operation of the Diablo Canyon Power Plant (DCPP), coastal land conservation, and
restoration of unitary tax treatment. The County is inviting all agencies that have received
DCPP unitary tax revenues to join a coalition in support of submitting the letter to the
California State Legislature. Participation would include inclusion of the City’s name
and/or logo on the letter and identification of a leadership point of contact.
While portions of the County’s draft letter align with the City’s adopted Legislative
Platform, the Platform does not authorize the City to take a formal position on whether
DCPP’s operating license should be extended, which is included in the County’s request.
Historically, the City has not taken a position on the license extension itself but has
Page 71 of 114

emphasized that any continued operation must prioritize public safety, appropriate fiscal
mitigation for local impacts, and long-term land conservation considerations.
The sections below summarize prior City actions and explain how the County’s request
both aligns with, and differs from, the City’s Legislative Platform and Council -adopted
guiding principles regarding DCPP. Should the Council wish to sign on to this letter
(Attachment A) and/or provide direction for future advocacy related to DCPP’s operating
license extension, this direction could be incorporated into the City’s 2026 Legislative
Platform update, planned for adoption in April 2026.1
Alignment with Guiding Principles and the Legislative Platform
The County’s draft letter includes three primary requests from the Legislature:
1. Support the Nuclear Regulatory Commission’s regulatory approval process and
establish a state licensing pathway to authorize DCPP to operate for up to 20
additional years.
2. Enact Legislation restoring historic pre-decommissioning unitary tax treatment for
DCPP including land valuation for the duration of its extended operations or
provide alternative equivalent financial mitigations.
3. Support the California Coastal Commission’s land conservation and public access
plan for lands surrounding Diablo Canyon, in coordination with appropriate
regulatory and conservation agencies.
Since the first component requests legislative action specific to a single facility and
project, it does not fall under the current Legislative Platform . Historically, the City has not
taken a formal position on the extension or closure of DCPP. However, in 2016, when
PG&E first announced the planned closure of the facility, the City Council adopted guiding
principles to inform staff participation in regulatory and stakeholder processes. Those
principles emphasized the City’s interest in “a seat at the table” and ensuring community
safety, fiscal stability, and long-term planning, including the following:
1. Ensure the continued safe operation of the DCPP and the health and safety of
the community. The primary focus is the emergency preparedness funding
extension but may also include other public safety related activities.
2. Be involved in creating solutions that will lessen the short- and long-term
financial impacts to the community. This could include a longer runway on tax
offsets to ease the transition, direct funding for programs impacted by the loss
of tax revenue and other direct financial contributions. A tangential issue that
may be addressed is the fair and equitable cost sharing between ratepayers
and PG& E corporate assets and shareholders.
3. Investigate opportunities for job creation and economic diversification.
1 The County’s December 22nd request sought confirmation of participation by January 10, 2026. However,
due to the proximity to the holidays, the City’s first regularly scheduled Council meeting not occurring until
January 13, and due to the need to allow adequate time for public noticing and outreach, the City Manager
advised the County that Council direction would not be possible until January 20. Several other cities in the
County are in a similar position with the need to obtain Council direction at public meetings occurring later
than January 10th, and County staff have confirmed that this delay is acceptable.

Examples of this could include creation of a research and development facility
located in the region, alternative energy generation technologies (small scale),
job training programs and seed funding for relevant economic programs and
opportunities. These opportunities could involve direct funding and/or
commitments for a certain amount of jobs remaining in the community for a
specified amount of time.
4. Develop a plan to address the potential long-term impacts of closing a nuclear
facility. This includes spent fuel management, decommissioning and local
vendor preference for request for offers (RFO) for new energy sources.
5. Explore the future use of the land and related facilities. This could include
desalinization, large scale energy generation and general land designation
(open space, development, etc.).
Following these guiding principles, the City of San Luis Obispo participated in
coordinating and forming a Coalition of Cities that worked in tandem with the County and
other significantly impacted organizations, including the San Luis Coastal Unified School
District (SLCUSD), to successfully establish a number of mitigation measures to address
some of the economic impacts of the plant’s planned closure. This led to a settlement
agreement entered into among a number of parties and presented to the California Public
Utilities Commission (CPUC) in 2016 as part of PG&E’s ratemaking process intended to
address needs associated with the planned closure of the DCPP. Ultimately, statutory
authority (SB 1090) was provided to implement a number of provisions in the settlement
agreement, including funding to the parties to address anticipated economic impacts of
the closure.
Following the enactment of SB 1090 in 2018, state energy policy shifted in response to
growing electric grid reliability concerns. In 2022, the Legislature introduced, and
ultimately adopted, SB 846 as an urgency statute, directing the CPUC to reverse its prior
decision to have the plant closed and authorize PG&E to pursue extended operations
through at least 2030, subject to federal license renewal by the Nuclear Regulatory
Commission and additional state approvals related to coastal permitting, environmental
compliance, and emergency preparedness, many of which remain underway. In 2022,
the City joined a coalition letter regarding SB 846 that did not take a position on license
extension, but emphasized the following nine key points:
1. Safety: Safe operation and regulatory oversight must remain the top priority.
2. Time-Limited Extension: Any license extension should be finite and tied to
renewable replacement readiness.
3. Renewables First: The State should accelerate renewable energy deployment
and remove regulatory barriers.
4. Land Use Planning: Extended operations should not hinder Central Coast clean
energy or economic development and planning for future use of Diablo Canyon
lands, including Parcel P, should continue.
5. SB 1090 Certainty: Prior mitigation funds should be explicitly protected from
clawback.
Page 73 of 114
6b
6. Fiscal Mitigation: Cities should be compensated for extended impacts beyond
the original closure timeline.
7. Land Conservation: Coastal lands should be preserved in consultation with Tribal
communities.
8. Local Workforce: PG&E should prioritize local labor and workforce transition.
9. Spent Fuel: A long-term solution for spent nuclear fuel is required.
In parallel, the community has continued planning for eventual decommissioning through
efforts such as the Diablo Canyon Decommissioning Engagement Panel. While the City
will experience a relatively modest fiscal impact of approximately $76,000 annually in
unitary tax revenue losses following the full depreciation of DCPP under SB 1090, the
SLCUSD has documented substantially greater impacts. District reports show that unitary
tax revenues from DCPP were approximately $3.7 million in 2024-25 and had been
declining significantly since 2018. The total loss of this revenue stream starting in 2025 -
26 has contributed to budget reductions of roughly $5 million in 2024 –25, with additional
reductions anticipated for the District. These significant financial impacts to community
partners like the District are addressed in the County’s proposed advocacy letter, which
seeks legislation requiring the reinstitution of the unitary tax.
The second and third items listed in the County’s proposed letter (regarding unitary tax
and land conservation and access) are consistent with the City’s adopted priorities and
Legislative Platform. These elements align with the City’s guiding principles, Major City
Goals as well as the following Legislative Platform planks:
Finance & Governance #1: Support meaningful fiscal reform that allows each
level of government to adequately finance its service responsibilities while
continuing to support efforts to protect the City from loss of revenues due to State
take‐aways and unfunded State or Federal mandates.
Parks and Recreation and Natural Resources #1: Support State and Federal
funding and other measures to promote the acquisition, protection, preservation
and restoration of natural resources, open space, coasta l resources, signature
landforms, wetlands, and park development, including continued funding for the
Land and Water Conservation Grant Program and for the California Conservation
Corps.
Parks and Recreation and Natural Resources #7: Support funding to reduce or
mitigate negative impacts to vital regional and community services and enhance
public access to parks, open space, after school programming, senior services,
facilities that promote physical activity, protect natural resources, and strengthen
safety and security
Previous Council/City Action
July 2016: The City Council considered its stance on the DCPP Closure and approved a
set of guiding principles to guide staff in the process of providing input during stakeholder
discussions and in any potential CPUC filings as it relates to PG&E’s commitment to the
community.
Page 74 of 114

September 2016: To ensure equitable consideration of the adverse impacts of the
retirement on area cities, the City joined the Coalition of Cities including San Luis Obispo,
Arroyo Grande, Atascadero, Morro Bay, Paso Robles and Pismo Beach. The Coalition
filed a joint request before the CPUC asking the state regulatory agency to formally hear
their concerns regarding key impacts related to the closure.
2016-2017: Numerous parties, including PG&E, labor and environmental organizations,
the County of San Luis Obispo, the SLCUSD, and the Coalition of Cities, participated in
CPUC proceedings. Ultimately, a settlement agreement was established that included
short-term community impact mitigation funding based on the assumption that the plant
would close in 2024–2025 but did not address long-term fiscal impacts associated with
extended operations or ongoing unitary tax treatment. On November 21, 2017, Council
authorized the City to advocate for legislation (if necessary) to fund the Community
Impacts Mitigation Program (CIMP).
March 2018: Staff gave the City Council an update on the status of the DCPP closure
settlement and sought Council approval for the City’s financial participation in a region al
economic and fiscal impact analysis following the unfavorable CPUC decision, which
excluded the CIMP. The City shared its guiding principles to the Diablo Canyon
Decommission Engagement Panel in May 2018 and t he Coalition advocated throughout
2018 and pushed for the passage of SB 1090 which was a California state law enacted
to implement key elements of the original Diablo Canyon Joint Proposal noted above.
August 2022: The City signed on a Coalition letter in August 2022 expressing
considerations and concerns for SB 846 (2022). SB 846 allowed DCPP to continue
operating past the retirement date and was enacted as an urgency statute to address
near-term grid reliability risks.
Public Engagement
Notice of this agenda item was provided through the meeting's posted agenda. The public
may submit comments in writing before the meeting or share their input during the public
meeting.
ENVIRONMENTAL REVIEW
The California Environmental Quality Act (CEQA) does not apply to the recommended
action in this report because the action does not constitute a “Project” under CEQA
guidelines Section 15378.

There is no fiscal impact associated with signing onto the County’s draft letter. Through
FY 2024-25, the City received approximately $76,000 annually from the Essential
Services Mitigation Fund and a one -time $1.8 million Economic Development allocation
in FY 2018-19, as approved through SB 1090. The expiration of these revenue streams
were accounted for in the City’s adopted FY 2025–26 budget and revenue forecasts.
ALTERNATIVES
Draft an Independent Advocacy Letter. Prepare an advocacy letter limited to elements
consistent with the City’s adopted Legislative Platform. Council may also direct staff to
incorporate specific policy positions or elements in this alternative letter, as desired. Staff
would draft the letter and send it to the Mayor for signature consistent with Council
direction.
Take No Action. Receive and file the County’s invitation and take no action at this time.

To: Members of the California State Legislature
Cc: Relevant Legislative Committees
Subject: Request for Legislation Supporting Extended Operations of Diablo Canyon Power Plant,
Coastal Land Conservation, and Restoration of Unitary Tax Treatment
Dear Members of the Legislature:
On behalf of the County San Luis Obispo Board of Supervisors, we write to express our firm
support for legislative action to enact measures authorizing Diablo Canyon Power Plant (DCPP)
to operate for up to twenty (20) additional years, restore unitary tax treatment for DCPP, and
support coastal land conservation and public access near the facility.
As the host county for California’s only operating commercial nuclear power plant which provides
approximately 9% of the State’s total generation of power, San Luis Obispo County recognizes
Diablo Canyon as a critical component of the State’s clean energy infrastructure. Extending the
plant’s operational life for up to 20 years would provide stable, carbon free baseload power that
strengthens grid reliability, reduces greenhouse gas emissions, and advances California’s clean
energy and climate goals.
Continuation of operations, however, must be accompanied by fiscal fairness for the communities
that host and support the facility. We therefore urge the Legislature to restore pre-
decommissioning unitary taxation for DCPP during any extended period of operation. Historically,
unitary tax revenues have been distributed to the County, cities, school districts, and special
districts, supporting essential public services, educational programs, infrastructure maintenance,
and public safety. Restoration of this tax structure is critical to maintaining the fiscal stability of
local governments and public agencies.
If restoring the pre-decommissioning unitary tax treatment proves infeasible, we request alternate
financial mitigations to the County and local jurisdictions impacted by exemptions of taxable value
on the DCPP during the period of extended operations established by the statutory prohibition
against including operating costs in PG&E’s rate base.
In tandem with extended operations, we support further conservation and public access
frameworks for lands surrounding Diablo Canyon. Protecting these coastal and natural resources
ensures long term environmental stewardship while providing opportunities for responsible public

access and public benefit. This balanced approach of clean energy, fiscal stability, and
environmental conservation serves both local communities and the broader interests of the State.
In addition, future DCPP allocations related to changes in the values being assessed for portions
of the property that may legislatively transition from highest and best use assessed acres of land
towards lower value assessed acres of land due to new conservation restrictions should not
financially penalize the affected region with lower assessed revenue figures.
Accordingly, we respectfully request that the Legislature:
1.Support the Nuclear Regulatory Commission’s regulatory approval process and establish
a state licensing pathway to authorize DCPP to operate for up to 20 additional years.
2.Enact legislation restoring historic pre-decommissioning unitary tax treatment for Diablo
Canyon Power Plant including land valuation for the duration of its extended operations
or provide alternate equivalent financial mitigations.
3.Support the California Coastal Commission’s land conservation and public access plan for
lands surrounding Diablo Canyon, in coordination with appropriate regulatory and
conservation agencies.
Taken together, these actions represent a prudent and forward-looking policy framework that
balances California’s clean energy needs with local fiscal health, environmental protection, and
community interests.
Thank you for your attention to this important matter. We stand ready to work collaboratively with
the Legislature to enact legislation that reflects these priorities and supports a sustainable and
equitable future for San Luis Obispo County and the State of California.
Sincerely,
Chair
County San Luis Obispo Board of Supervisors

Context
1.Support the Nuclear Regulatory Commission’s regulatory
approval process and establish a state licensing pathway to
authorize DCPP to operate for up to 20 additional years.**
2.Enact legislation restoring historic pre-decommissioning
unitary tax treatment for Diablo Canyon Power Plant including
land valuation for the duration of its extended operations or
provide alternate equivalent financial mitigations.
3.Support the California Coastal Commission’s land
conservation and public access plan for lands surrounding
Diablo Canyon, in coordination with appropriate regulatory
and conservation agencies.
** License extension advocacy is outside the scope of current Legislative
Platform and guiding principles
County is inviting impacted agencies to join a coalition letter to the State including
three primary requests from the Legislature regarding DCPP:
3
Background
•2016-2017: City developed five guiding principles in advance of anticipated DCPP licensing
conversations and potential closure:
•Community Safety
•Fiscal Mitigation
•Jobs & Economy
•Long-Term Planning
•Future Land Use
•The City of SLO participated in and help form a Coalition of Cities that worked in tandem with
the County and San Luis Coastal Unified School District (SLCUSD), and other agencies to
successfully establish several mitigation measures to address some of the economic impacts
of the plant’s planned closure.
4
Background
•2018: SB1090 passed in 2018 and implemented one-time Economic Development funding
and essential services mitigation funding, among other things, to address upcoming plant
closure.
•City received a one-time payment of $1.8 million in Economic Development funding
•City has received approximately $76,000 annually through Essential Services Mitigation
Fund (ended in 2025)
•2022: Coalition of cities once again advocated for nine key points as the Legislature
considered SB 846, an urgency statute directing the CPUC to authorize PG&E to pursue
extended operations through 2030:
1.Safety
2.Time-limited extension
3.Renewables first
4.Land use planning
5.SB 1090 Certainty
6.Fiscal Mitigation
7.Land Conservation
8.Local Workforce
9.Spent Fuel
5
Where things are at now
State Direction: The State has authorized continued operations at DCPP through at least
2030, subject to federal and state approvals (SB 846).
Regulatory Process Ongoing: Safety oversight remains with the Nuclear Regulatory
Commission. Federal licensing, coastal permitting, and emergency preparedness reviews
are still underway.
Unitary Tax Dilemma: State law assumed permanent closure, triggering accelerated
depreciation that eliminated unitary tax revenues to local agencies; however, the plant
remains in operation, creating a mismatch between ongoing impacts and tax treatment.
Fiscal Reality: City impacts are modest; other community partners, including school
districts, face significant ongoing revenue losses.
6
Alternatives
1.Draft an Independent Advocacy Letter consistent with existing legislative
platform and Council direction
2.Take No Action. Receive and file the County’s invitation and take no action at
this time.
Recommendation:
Receive the County of San Luis Obispo’s invitation to join a request for State legislation
related to the Diablo Canyon Power Plant and provide direction to staff regarding
participation in the letter drafted by the County.
7
Alternative
1.Council could decide not to create an ad-hoc committee and instead direct staff to
make recommended updates. In this alternative, staff would incorporate recommendations
from Cal Cities and other relevant sources to update the legislative platform. The draft 2025-
26 Legislative Platform would then be presented to the Council for approval in April 2026.
2.Council could decide not to create an ad-hoc committee and continue with the current
legislative platform. If this alternative is chosen, there may be changes in policy landscape
that are not addressed in the current platform.
3.Council could decide not to adopt a legislative platform. Under this alternative, the City
would not be able to write letters or reach out to legislators on key issues without requesting
review and approval of the letters by Council each time. This would limit the impact that the
City might have on pending legislation due to the time constraints on fast-moving bills and
issues. Adopting a legislative platform is considered a best practice.
8
2016 Guiding Principles (1-3)
1. Ensure the continued safe operation of the DCPP and the health and safety of the
community. The primary focus is the emergency preparedness funding extension but may also
include other public safety related activities.
2. Be involved in creating solutions that will lessen the short- and long-term financial impacts
to the community. This could include a longer runway on tax offsets to ease the transition, direct
funding for programs impacted by the loss of tax revenue and other direct financial contributions. A
tangential issue that may be addressed is the fair and equitable cost sharing between ratepayers and
PG& E corporate assets and shareholders.
3. Investigate opportunities for job creation and economic diversification. Examples of this could
include creation of a research and development facility located in the region, alternative energy
generation technologies (small scale), job training programs and seed funding for relevant economic
programs and opportunities. These opportunities could involve direct funding and/or commitments for
a certain amount of jobs remaining in the community for a specified amount of time.
9
2016 Guiding Principles (4-5)
4. Develop a plan to address the potential long-term impacts of closing a nuclear facility.
This includes spent fuel management, decommissioning and local vendor preference for request
for offers (RFO) for new energy sources.
5. Explore the future use of the land and related facilities. This could include desalinization,
large scale energy generation and general land designation (open space, development, etc.).
10
2022 Advocacy on SB 846 - Summary
1.Safety: Safe operation and regulatory oversight must remain the top priority.
2.Time-Limited Extension: Any license extension should be finite and tied to renewable
replacement readiness.
3.Renewables First: The State should accelerate renewable energy deployment and remove
regulatory barriers.
4.Land Use Planning: Extended operations should not hinder Central Coast clean energy or
economic development and planning for future use of Diablo Canyon lands, including Parcel P,
should continue.
5.SB 1090 Certainty: Prior mitigation funds should be explicitly protected from clawback.
6.Fiscal Mitigation: Cities should be compensated for extended impacts beyond the original
closure timeline.
7.Land Conservation: Coastal lands should be preserved in consultation with Tribal communities.
8.Local Workforce: PG&E should prioritize local labor and workforce transition.
9.Spent Fuel: A long-term solution for spent nuclear fuel is required.
