Public comment presented during the September 24, 2025 Engagement Panel Meeting:

Lindsay Fowler Hello, I am Lindsay Fowler, and I'm glad to be in front of you, ladies and gentlemen, of a panel that has been tasked to do a certain thing at a certain place at this time. And, uh, to bring us back to the here and now, I'd like to cover three points. The, the site, the infrastructure, and the personnel. The site itself is rather well secured and, um, or already exist as a functioning power plant, um, doing a rather good job of it. And hopefully it'll be extended into the future, continuing to do a good job. Um, based on the security of this site, I would like you also to consider small modular reactors, which is a relatively new technology, but shouldn't just be scattered over the countryside at various locations. It being in a secure place would be just fine as it, uh, could possibly be supplemented into the, um, infrastructure, which is the second point.

Public comment presented during the September 24, 2025 Engagement Panel Meeting:

Nina Babiarz Uh, my first name is Nina, actually, it's pronounced, uh, Nina as well. Last name Babiarz I'm a founding member of Public Watchdog down here in, uh, San Diego. And, uh, I also was, uh, living in Pittsburgh in 1979, uh, during the three Mile Island meltdown. I was a, uh, engineering and construction news reporter for McGraw Hill. That's what brought me to California to open an office for them. I just wanna say from personal experience here in San Diego, when we experienced a very abrupt, uh, closure of, uh, Santa Ano free nuclear power plant, uh, due to a radiation leak, uh, we really didn't have any problem. So, you know, the big threat of, uh, not having Santa Ry operable, uh, just never panned out. Uh, we did just, uh, fine. And, uh, with regard to the concern of, uh, jobs and job creation, well, there's still, uh, there's still an enormous amount of work that's going on because there're decommissioning and demolishing the plant and, uh, the parking lot is full of Edison employees.

Public comment presented during the September 24, 2025 Engagement Panel Meeting:

GINO ALANO Can you, can you hear me fine? Thank you. Uh, yes. So, uh, I am, uh, a, uh, member of the Tini people. Uh, the, we are the ancestral people of, uh, the territory in which the, uh, the, the, the, uh, plant sits along with, uh, the surrounding area. And we were highly involved in a half a decade or so ago with the first relicensing of, uh, Diablo Canyon. And we pushed hard, uh, to make the point that, you know, the aging infrastructure, which is not being discussed here, uh, the fact that we have faults right outside this, uh, power plant and the high risk of tsunami flooding along with, you know, the collection of radioactivity, uh, reactive materials there that have not been, uh, you, you know, disposed of and, and a slew of other issues. And it was understood that it just did not make sense to keep this plant open, especially with the high risks, uh, especially with the aging plant.

And so, you know, we, we hope that you consider that again, that the, you know, that we also said that, you know, electricity, the demand for electricity is going to increase because of technology, and that a vast majority of this is a money grab. That it's, you know, it, the, the plant is being, you know, uh, kept open for the simple purposes to allow for, uh, to provide electricity for non-essential, uh, use. And there are other means of, uh, of forms of, uh, of energy that can be utilized, that will cut down the risk of something catastrophic happening at Diablo Canyon. You know, we've mentioned that everybody here listening to this is something we pray never, ever in our lifetime or ever we pray that the, the, the plant is, you know, removed that something as catastrophic as Fukushima. Matter of fact, the lacing, uh, hearings were right after, uh, the Fukushima event.

And all of the traits, all of the terroristic of Diabo Canyon are extremely similar to Fukushima in terms of where it sits on the coastline, how close it sits to fault lines, and all of the above. So, you know, somebody had mentioned earlier that there was once a plan to have 20, or 30 or 80 some huge amount of power plants, uh, built. And now that plan is gone. No, we, they're not doing it. So, you know, there's, there's a reason behind that. And I understand that this is a plant that's there that's been providing electricity, however it is aging, uh, and it is at high risk for some catastrophic event. And please reconsider, uh, uh, keeping the plant open. Thank you.

CARL WATZ Next speaker. Hi, my name's Carl Watz. I represent Fish and Transition. I live in Burbank. Um, I, I don't even know where to start with Mark Jacobson's, uh, speech, or, I've se heard him speak many times, and I never heard him more frantic. I think part of the reason is there's a nuclear renaissance that is ripping the world right now. He is absolutely wrong about nuclear development. There are 70 new reactors under, under construction right now, and a hundred more planned. And if the United States can't keep up with it, we are gonna be buried by other, other countries, other man manufacturers in other countries. Now, mark, besides, besides rolling out the litany of, of lies and mis misrepresentations about nuclear energy that we've been hearing for 50 years about nuclear waste and about, uh, uh, uh, potential nuclear, uh, meltdowns, whatever, which haven't, hasn't happened since this 2011 and, uh, never in a reactor built in the last 50 years.

Um, mark is totally misrepresents on his charts, the generation that he shows. There's, right now at this very moment, there is today, all day long, there were 10 gigawatts of natural gas burning that were nowhere, nowhere represented on Mark's charts. He just simply erased them because the fact is that wind and solar are increasing consumption of natural gas. It's gone up dramatically since 2011 with California's adoption of renewables. And, uh, that part of that reason is that wind and solar require natural gas for backup. They require natural gas to balance the fluctuations in their, in their intermittent, in unpredictable output. So, uh, uh, the, uh, American Petroleum Institute has an advertising campaign saying why natural gas will, will be a feature of the new renewable era. And it's, they, they're exactly right. They're, they love the fact that, um, that, uh, uh, Preco Institute where Mark works is, is promoting, is promoting, uh, wind and solar because they, they stand to make billions in billions in year, in, uh, every, every year that, uh, wind and solar are generating electricity. So, um, just in conclusion, I don't, I don't have, uh, 25 minutes to speak like Mark does to ramble on, but I, I'm, it makes me really kind of, uh, ill to take care of him, talk about clean, safe nuclear electricity the way he does. Thank you.

JOHN KING Hi, I'm John King. I'm, um, local citizen. I live in Aurora Grande, and I'm a member of the, uh, San Luis Obispo, uh, N-A-A-C-P. And, uh, I'm curious, it has come to my attention that the, uh, pg and e has not made public, despite several requests from other members of the community, their community benefit plan, that was a requirement of a $1.1 billion civil nuclear credit award and the midterms payment agreement they received from the US Department of Energy that facilitated the extended life of Diablo Canyon. According to the contract, the first such plan was due to be reported on in February of 2024, and has yet not been provided as noted in the outreach literature from the Department of Energy, the Community Benefit Plan attributes. Attributes and goals are stated to be that the community benefit plan must describe how diversity, equity, inclusion, and accessibility objectives will be incorporated into the project. The plan should detail how the applicant will reduce barriers to employment and advancement opportunities for underrepresented individuals by providing supportive services and through partnerships with underrepresented business minority serving institutions, training organizations that serve workers who face barriers to accessing quality jobs.

We have seen a copy of the pg e annual report to the Department of Energy dated June 10th, 2024, but it only contains a matrix of the aspirational and unquantified goals and results. Since this annual report was never distributed to the community and apparently shared only between pg and e and the Department of Energy, it cannot have been intended to, nor did it serve as a community benefits plan. Yet we know pg e can create a genuine community benefit plan if it wants to. It did so for more recent Department of Energy, title 17 loan and highly detailed plan printed on pg e letterhead, posted publicly on the company website to date San Luis Obispo and double a CP and underserved minority citizens have not been contacted for involvement in any way of any kind by pg and e as a minority serving institution of longstanding in this community, it seems at least an egregious oversight or perhaps even an intentional act of disregard on the part of pg and e.

In addition, Questa College, the only community college of San Louis Deiss County, with a 38% Latinx enrollment, has in no way been benefited, uh, from this enormous award designed to aid in workforce development. Even though Questa colleges nuclear tech training operated from 2017 to 2022, as a matter of due diligence regarding the use of federal funds or the lack thereof, we have alerted Congressman Salud Caral of the 24th district up to our concerns. We at the N-A-A-C-P of Sloane County will be actively engaging with him in this manner. We look forward to your timely responses to this important request, and I will gladly provide you with contact information to reach me and the N-A-A-C-P of San Luis Obispo County. Thank you.

Public comment presented during the September 24, 2025 Engagement Panel Meeting:

DAVID WEISSMAN A good evening. David Weissman, executive Director of the Alliance for Nuclear Responsibility. Um, this evening, we once again had a chance to gaze into the crystal ball of energy demands and projections, both short and long term. This is not California's first time at that rodeo. Back in 1972, the state assembly requested the Rand Corporation to look into the same information. At that time, we had an installed capacity of 35,000 megawatts in the state. The utilities in response to the RAND Corporation predicted that by the year 2000, we would be requiring between 90 and 150,000 megawatts of electricity power of the state. As we saw in the chart today in 2022, we peaked at 52,000 of those. One cannot imagine that overbuilding a system always falls on the backs of beleaguered rate payers. And as we've for heard how much energy really is needed for the 60 or so hours a year that reach that peak demand.

Uh, it is also important to maybe think that past this prologue again, having been down this road once before, and I am reminded by Mr. Ern of the very agency that he works for. In that same 1972 ran report, it reached the desk of a Mr. Charles Warren in the assembly. And Mr. Warren proposed legislation AB 1575 that created the California Energy Commission. And I will just read a few of the words from Mr. Warren's oral history interview at uc, Berkeley. It became clear to me that it would be impudent to rely on nuclear to the extent that the utilities had planned. So without mentioning nuclear power, but relying on significant land use and water requirements of siting and operating the 100 large power plants, the utilities projected might be necessary in California. By the year 2000, we wrote legislation which proposed significant changes in our state's energy policy.

All in all, AB 1575 has withstood the test of time very well. It was the first to challenge the policies of energy inefficiency of the utilities, and to point out that energy planning by the utilities was devoted more to maximizing profits than to the public's interest in a rational and reasonable energy program. Its anti-nuclear implications stem from its objectives of more realistic estimates of energy, electricity, demand, reduced demand due to nce, conserv conservation and energy efficiencies, and then electricity generation by alternate systems. He concluded. And all that was hoped has come to pass. Not too long ago, California utilities were planning to build as many as 80 nuclear power plants by the year 2000. Today, there are no plans for building nuclear plants in California. So said Mr. Warren, in 1984, perhaps it is time to consider, once again Mr. Warren's words and for the agency that he envisioned and brought to life to fulfill the vision that he beheld at the time of its birth. Thank you.

Dear Diablo Canyon Decommissioning Engagement Panel,

Thank you for the opportunity to submit a comment on the future of Diablo Canyon and its role in California’s energy system.

California’s energy transition requires an all-of-the-above approach that leverages the strengths of renewables, storage, demand flexibility, and firm clean power like nuclear. While wind and solar provide abundant electricity, and batteries add flexibility, none can replace the full suite of grid-stabilizing services provided by Diablo Canyon’s large, spinning generators. These services include:

- Inertia: resisting sudden frequency disturbances in milliseconds, buying time for the rest of the grid to respond.
- Harmonic damping; smoothing waveform distortions that grow in inverter-heavy systems, protecting electronics and industry.
- Voltage regulation; supplying reactive power and stabilizing transmission voltages, preventing cascading failures.

This is why the decision to extend Diablo Canyon for 5 years was so critical. That action alone is saving Californians hundreds of millions of dollars on electricity bills while cutting reliance on gas-fired power. We can multiply those benefits by pursuing the full 20-year relicense from the NRC, which Diablo Canyon is already preparing for. We know California will need this power for decades, and the investment we are making now only makes sense if we secure its long-term operation.

Looking further ahead, lifting the moratorium on new nuclear energy in California would give us the option to complement renewables with even more firm, reliable clean power. That pathway would conserve land, lower system costs, and further reduce dependence on fossil fuels.

At the same time, long-term planning must continue to prioritize the voices of San Luis Obispo, yak tityu tityu yak tilhini Tribe, and the skilled workforce who have kept Diablo Canyon safe and reliable.

Diablo Canyon is not an obstacle to clean energy expansion. It is a cornerstone of a balanced solution that has proven a robust pathway forward. Pairing renewables with nuclear gives Californians affordability, reliability, and resilience.

Respectfully submitted,
Ryan Pickering

As an advocate for the extended operation of Diablo Canyon Power Plant (DCPP,) I'm frustrated with the DCDEP's ongoing focus on essentially everything *other* than extended operations. The state legislature and the governor spoke clearly with the enactment of SB 846 (Dodd, 2022.) In December, 2023, the CPUC eventually agreed with the state legislature and governor. On September 17, 2025 your form still says, "Proposed Extension of DCPP Operations."

In the interest of efficiency, I believe the DCDEP should be disbanded. The DCISC already provides an avenue for the public to continue to weigh in on DCPP extended operations via its three local meetings per year.

I look forward to your confirmation that you received my message and will act on it.

Good evening,
I am a concerned parent of the SLCUSD and trying to sort out how the district's current budget deficit is affected by the loss of funding from Diablo Canyon. Dr. Prater keeps referencing SB 1090. Can you explain to me why the school district does not know whether there will be any continued funding from Diablo Canyon in some form in future years? Is there an effort in Sacramento or elsewhere to provide new terms to the Unitary Tax? Or, direct other sources of funding from PG&E to the District that they can consider in their budgeting process? It is difficult to hear them making such detrimental temporary cuts to their services, because of what seems to be a temporary unknown with this large revenue stream from PG&E. From a layman's view, it would seem that if the terms of the Essential Services Mitigation Fund were set to expire in 2025 in alignment with the plant's decommissioning, but the plant is not now being decommissioned and is creating revenue for PG&E, then some sort of payment would need to be made to the district and other government entities relying on this funding for their government services. As a final inquiry, I am curious if there is a member of this panel that works with SLCUSD or vice versa, to ensure expedient and direct lines of communication?
I look forward to hearing back and thank you for any insight or information you can provide.

First, thank you to the panel for your time and concern and for holding the public meeting on September 18. Thank you also for posting the video of the meeting as I was not able to attend either online or in person.

My comment is that it makes no sense to say that something is safe because we’ve had no major issues to date. Fukushima was “safe” until it wasn’t. Same with Chernobyl. Do we have to wait for a disaster with the spent fuel at SONGS or Diablo Canyon before “scientists” understand how unsafe radioactive spent fuel is?

The more important issue is why should we create MORE highly radioactive waste - especially here in California where we have enough renewables and battery storage to meet our power needs. Yes, Diablo Canyon currently provides 8% of the state’s electricity. Meanwhile, so much renewable energy is waiting to get online. The burden is all put on us, the residents and ratepayers. The costs of operating a non-profitable source of electricity, the costs of keeping the spent fuel “safe” and the enormous costs should something happen that would create a massive radioactive release.

MS. BAKER:· Okay, thank you.· Sheila,
S-H-E-I-L-A, Baker, B-A-K-E-R.· I don't agree that it's
a popular idea that holes and big, big places that
should be dug in the earth, and with this substance
placed in the earth.· And I -- I think that it's not a
sustainable way, I mean, we are so used to using this
planet to our -- whatever we want, okay, that we do
things that we don't even stop and think that not
everyone feels that way and that digging holes and
placing radioactive stuff in the earth is not really
very good.· The other comment I want to make is -- or
question, are the two states that have been designated
as interim storage states, that would be Texas and
New Mexico, my part of the objection would be the
transportation on freeways, highways, and freight on the
railways.· So anyways, thank you so much.

MS. MCCLINTOCK:· Hello, so I'm a public
citizen, I live in Ventura right now, and my name is
Francene McClintock, F-R-A-N-C-E-N-E, McClintock,
M-C-C-L-I-N-T-O-C-K.· And they mentioned this, I should
have my glasses on, Nuclear Waste Policy Act, I think
you said 1982, I think, I don't know, I thought it was
'85, but I guess it's '82, and I didn't understand the
deference between -- I thought it differentiated between
military and commercial, but it almost sounded like that
gentleman was talking about one dump where military and
commercial nuke waste would go into a repository, so if
we really did rolling stewardship and hard and on-site
storage above ground, could that go on a military base?
I guess is my question.
· · · · · And then I also wanted to ask about Curie's,
because Madam Curie, I guess, died of cancer, and that
was the whole idea of radioactivity, is it has Curie's.
So in the low level waste dump phase, they always talked
about square feet or cubic feet that you had to have the
snoop dump that was so big, and it sounds like here
you're talking about tons, and I'm just curious how many
Curies we are actually talking about in the
United States, military, commercial, in Russia, in the
whole world, et cetera.· Just I wish they would talk
about the Curies, because that is the reason we have to
isolate it from the biosphere.· Thank you, that's all.

MR. ALLEN:· Peter Allen, P-E-T-E-R A-L-L-E-N.
I lived in the Five Cities my whole life and I live --
reside in a small corner of San Luis Obispo, and I'm
really happy to be here.· I can see that everybody's
looking concerned, and I'm hoping that we can come --
I'd love to be on the panel, you all are very concerned
citizens, I'd love to set precedent that we can conquer
this for the whole world.· From what I've seen,
everybody is struggling, trying to do the right thing,
and they're hurting everybody in the planet, which it's
going to be.· But people have told me that this is going
to be a meltdown from nuclear wars to nuclear energy
plants, and so it's been a battle.· I believe
Nikola Tesla's knowledge was mothballed for future --
for people wanting to monopolize off of energy.· And so
anyways, I have some hot topics.
· · · · · So being that there's 30 years --
For 500 million years of waste is completely
absurd, and I wish I was smart enough to be a nuclear
engineer, physicist, and -- but I'm not, and -- but I
wish that they were reducing the fuel down to spent fuel
which it would be less of a waste and it'd be hopefully
easier to manage.· So I know they're reducing it down,
pulling the water out and processing it, but I think
it's absurd to put it into our drinking water, but it's
going to land there anyways when they put it in the
ocean and it circulates and it's -- it's what you don't
know that you don't know, just like sewer water, nobody
wants to drink it, but it's -- they're living off their
septic.· So -- so yeah, the legacy for future
generations and wanting to hide it from them for the
future, because they're wanting to save money, it hurts
my heart, and I know it hurts all of you here also
for -- for these dump zones in your backyard where your
grandchildren and future generations are going to be
potentially leaking and they're going to have cancers
and they're going to be on potassium pills.· So people
are getting hurt in these plants, working in
containment, where they have to be scrubbed down with a
wire brush, I don't know the correct thing, but
obviously, they get cleaned up and hopefully they can
live their life.· And when I was in Russia, I met a girl
who her dad went to Chernobyl for two hours to do
something after the meltdown -- okay, am I cut off?
Okay.· I'd love to be on the panel.

I would like to have a conversation regarding safe storage product i represent for Japanese company.
This product saves casks from earthquake vibration falling.

Diablo Canyon Decommissioning Engagement Panel
DCDEP Members
Chuck Anders
Facilitator

May 22nd, 2024

Hello Chuck Anders, Diablo Canyon Decommissioning Engagement Panel Members,

Many thanks for all that you and the Diablo Canyon Decommissioning Engagement
Panel Members do to create a better, safer word for us all.

There is a very real possibility that earthquakes off the coast of Vancouver, British
Columbia could trigger a nuclear meltdown at the Diablo Canyon power plant.

To explain this frightening scenario, let's start with the impact of climate change
caused by the Earth's rising temperatures. The World Meteorological Organization
stated that 2023 was the hottest year on record. (1)

Regrettably, these soaring temperatures can trigger a variety of catastrophes such
as volcanic eruptions, earthquakes and tsunamis due to the rapid melting of our
planet's glaciers and polar regions. (2)(3)

When glaciers and polar caps melt, their massive weight on the Earth's crust is
reduced. This causes the planet's surface to bounce back in what scientists call
an"Isostatic Rebound”. Isostatic rebounding can reactivate fault lines (4) leading
to more movement along the world's tectonic plates (5) and subduction zones.

The Pacific "Ring Of Fire" Subduction Zones:

Roughly 90% of all earthquakes as well as 75% of all the active volcanoes on Earth
take place along the Pacific "Ring of Fire" subduction zones. (6)

The Cascadia Subduction Zone:

The Ring of Fire's Cascadia Subduction Zone is a 700-mile long offshore fault that
runs from British Columbia to Northern California. (7)

On March 6, 2024, a peak of more than "200 earthquakes per hour" was detected by
Canada’s Northeast-Pacific Seafloor Observatory site off the coast of Vancouver Island,
British Columbia. (8) More earthquakes mean more stress build-up, ”says Zoe Krauss,
“the observatory dataset has allowed us to observe significant increases in earthquake
rates over the last few years.”

Sadly, Vancouver Island is located close to an active boundary between three tectonic
plates, the Pacific Plate, the Juan de Fuca Plate, and North American Plate. The Juan
de Fuca Plate is moving toward and underneath (subducting) the North American Plate
along the Cascadia Subduction Zone. (9)

Additionally, the Cascadia Subduction Zone is now considered one of the world's most
tectonically active regions. It has the potential of generating massive earthquakes like
the deadly and destructive March 11, 2011 magnitude 9.1 earthquake and tsunami that
struck off the northeast coast of Honshu, Japan which culminated in three nuclear
meltdowns at the Fukushima Daiichi nuclear power plant. (10)

Regrettably, the Cascadia Subduction Zone and the Northern San Andreas Fault meet
at a place called the "Mendocino Triple Junction" which is offshore of Mendocino
County, California.

A major offshore earthquake along the Cascadia Subduction Zone could trigger an
earthquake on California's San Andreas Fault Line according to geologist Chris
Goldfinger of Oregon State University. (11)

The San Andreas Fault System:

The San Andreas Fault is one of the world's largest fault lines, running more than 800
miles from Cape Mendocino, California to the Salton Sea. (12) Unfortunately, there's
a more-than-dangerous seismic link between the San Andreas Fault System and the
Diablo Canyon Nuclear Power Plant.

The Diablo Canyon Nuclear Power Plant:

In his July 26, 2011 California Energy Commission's Integrated Energy Policy Report,
Geologist Douglas H. Hamilton, Ph.D. stated that there are two dangerous fault lines,
the "Diablo Cove Fault" and the "San Luis Range/"IOF" Thrust", that are located directly
underneath Diablo Canyon's Unit 1 nuclear reactor and turbine generator building.(13)

The "east/west trending" Diablo Cove Fault runs offshore and intersects with the nearby
Shoreline Fault which in turn is connected to the Hosgari Fault Line (14), a component of
the San Andreas Fault System. (15)

Simply put, earthquakes off the coast of Vancouver Island, British Columbia could
reactivate the Cascadia Subduction Zone which in turn could trigger the San Andreas
Fault Line that's seismically linked to the Hosgri Fault, the Shoreline Fault and the Diablo
Cove Fault Line. The power stored within this network of linked faults could create an
earthquake sufficient to exceed Diablo Canyon’s safeguards. (16)

The idea that nuclear power plants are durable enough to withstand powerful earthquakes
and other external shocks is a total myth.

It is no longer rational for us to suffer the risks posed by the aging and embrittled Diablo
Canyon nuclear power plant. We need to remove this hazard from our coastline as soon
as possible. It's time to Close Diablo Down!

4) An Enhanced Seismic Activity Observed Due To Climate Change: Preliminary
Results From Alaska

The impact of human induced climate change on the rising temperature cannot
be neglected. Climate change can trigger catastrophes such as earthquakes,
volcanic eruptions, tsunamis and landslides due to melting glaciers and rising in
sea level.

When glaciers melt, the massive weight on the Earth's crust reduces and the crust
bounces back in what scientists call an "Isostatic Rebound”. The process can
reactivate faults and lift pressure on magma chambers that feed volcanoes, hence
increases seismic activity.

Vancouver Island is located close to an active boundary between three tectonic plates.
The Pacific Plate, the Juan de Fuca Plate and North American Plate. The ongoing
interaction among these tectonic plates has the potential to generate large earthquakes,

10) Additional Information About The Cascadia Subduction Zone:

The Cascadia subduction zone, which lies mostly off shore and extends approximately 700
miles from Cape Mendocino in Northern California to Northern Vancouver Island, Canada.

The Cascadia subduction zone is where the Juan de Fuca, Explorer, and Gorda tectonic plates
are subducting under the North American plate. It is now thought to be capable of producing
great earthquakes of magnitude 8 or 9, like those off Indonesia in 2004 and Japan in 2011.

Quakes Sometimes Trigger San Andreas Fault

Geologists Chris Goldfinger of Oregon State University said a major quake from the
offshore Cascadia fault zone could trigger California's San Andreas Fault.

12) What is the San Andreas Fault?

When we think of the next big earthquake, we think of the San Andreas fault. This
fault system is one of the largest faults in the world, running more than 800 miles
from Cape Mendocino to the Salton Sea.

-----------------

13) In his July 26, 2011 California Energy Commission's Integrated Energy Policy Report,
Geologist Douglas H. Hamilton, Ph.D. stated that there are "two dangerous faults" that
run directly underneath the Diablo Canyon nuclear power plant. The San Luis Range
Thrust and the Diablo Cove Fault.

The San Luis Range/"IOF" Thrust:

The San Luis Range Thrust as thus defined, underlies the Diablo Canyon nuclear power
plant at a depth as shallow as 1 to 2 km within Franciscan Formation or Cretaceous
Sedimentary Rock and is clearly seismically active. It has dimensions that suggest a
deterministic earthquake generation capability in the range of magnitude 6.75>M7.0.

The Diablo Cove Fault:

From the first establishment of Pacific Gas & Electric's Geoscience Department in 1985
through its presentation at its Senior Seismic Hazard Analysis Committee workshop in
the late 2011, the previously well-documented zone of faulting extended through the
foundation of the Diablo Canyon nuclear power plant's Unit One's turbine generator
and reactor containment was never mentioned.

-----------------

14) A USGS seismologist, Jeanne L. Hardebeck believes that a joint seismic event of the
Hosgri and Shoreline faults could exceed the plant’s design capacity for safe operation,
possibly reaching a magnitude 7.7.

Headline: Geometry And Earthquake Potential Of The Shoreline Fault, Central California

The Optimal Anisotropic Dynamic Clustering results show that the Shoreline Fault is a
single continuous structure that "connects" to the Hosgri Fault. The Hosgri fault dips
steeply to the east, while the Shoreline fault is essentially vertical, so the Hosgri fault
dips towards and under the Shoreline fault as the two faults approach their intersection.

https://pubs.er.usgs.gov/publication/70046870

-----------------

15) The Hosgri Fault

The Hosgri Fault is a component of the San Andreas Fault system.

Its movement is primarily reverse thrust, as well as exhibiting right lateral slip, and is
thought to be capable of generating earthquakes of up to magnitude 7.5.

https://en.wikipedia.org/wiki/Hosgri_Fault

-----------------

16) February 8, 2016 - Headline: Earthquakes On Thrust Faults Can Spread 10 Times
Farther To A Second Nearby Thrust Fault Than Previously Thought

The scientists found that an earthquake that initiates on one thrust fault can spread
10 times farther than previously thought to a second nearby thrust fault, vastly
expanding the possible range of "earthquake doublets," or double earthquakes.

Public comment presented during the May 22, 2024 Engagement Panel Meeting:

MR. DURAN:· Good evening, name is
Jonathan Duran, J-O-N-A-T-H-A-N D-U-R-A-N.· I am a
representative with the Western State's Regional Council
of Carpenters, Local 805.· That covers the Ventura,
Santa Barbara, San Luis Obispo area.· For us, as a
tradesman, Diablo's been a great place to find work.
Recently, we just had a -- one of the shutdowns, we had
about 60 carpenters out there, mill rights, and as I
said, other trades out there.· The one thing that -- as
I was listening to you guys speak about this is
opportunity for repurpose the property.· That's great,
that's fine.· But also include the people that are
actually going to build those facilities out there.
Include skilled and trained work force, include
accredited apprenticeship programs, include a livable
wage, because we all know here in San Luis Obispo
county, Santa Barbara county, Ventura county, it's
expensive.
· · · · · And being a tradesman, it's a good living.
And it's an opportunity for us to be able to have a
middle class and have an opportunity to provide for our
families out there.· Roughly in the area of -- the area
that I represent is about 2,000 members, and great
opportunity.· And as we're -- as we come through this
opportunity for this project -- and like I said, we're
looking at offshore wind, we're looking at the vista
storage battery, and we're looking at all these other
opportunities to be able to provide work for our members
within these counties and looking at the next generation
of carpenters.· So as we're doing that, we're also
trying to include, hey, opportunities for students that
are going to be going not to a four-year university but
to another four-year university and that's in the
trades, and they'll have an opportunity to be able to
work with your hands, have opportunities for
second-chance individuals, women, people that are coming
out of being incarcerated.· And those will allow people
to go and be able to live within the county and go back
and put the money back in to the area that we live.
· · · · · Again, I've been out at Diablo, it's a
phenomenal facility, it's very, very unique to be able
to go out there and look at that facility and just kind
of like tucked away up in those hills.· But at the end

of the day, what we're looking for is just the
opportunity to be able to have a conversation with
GO-Biz and have the players here and be able to kind of
go hey, think about the individuals that are going to be
building these facilities that if it does trig, be
turned on, hey, we're the ones that are going to be
there being able to build those new facilities, those
new trails, whatever it might be, but include the
trades, include especially us, the carpenters, and but
again, thank you so much for your time, thank you.

MS. BROWN:· I'm Marty Brown, and I've lived
in -- M-A-R-T-Y B-R-O-W-N, and I've lived in Atascadero
since 1972.· And my -- I was concerned about the safety
aspects of Diablo Canyon with the earthquake risks and
the evacuation plans if necessary.· I have a comment and
a question to make.· My comment is the redevelopment of
Parcel P plans after decommissioning are very exciting
and will serve our county well, a lot to look forward
to.· And my question is if PG&E is successful in getting
Diablo Canyon's operating license extended to 20 years,
that will add significantly to the high level nuclear
waste on site.· Would that affect the repurposing of
Parcel P?· That is my question.· Thank you.

Public comment presented during the May 22, 2024 Engagement Panel Meeting:

MS. TUCKER:· Good evening, everyone.· My name
is Mona Tucker, M-O-N-A T-U-C-K-E-R.· I'm the tribal
chair for Yak Tityu Tityu Yak Tilhini Northern Chumash
tribe of San Luis Obispo county and region, and we --
everything that happens at Diablo lands is of special
interest to our tribe as this is land that was stolen
from us, it was taken.· We were removed violently from
there, there was no compensation or agreement.
· · · · · I do have a question tonight about the
offshore substations.· Will there be three offshore
substations?· And then regarding the onshore
substations, it appears there will be three, will they
run along the coastline as say from north to south,
taking up a lot of the -- destroying a lot of the
coastline area?· Thank you.

Dear Diablo Canyon Engagement Panel,

I represent a business interested in the purchase of the seawater desalination brines for a proposed magnesium facility. Please direct me to the appropriate person.

Hi, i read your blog from time to time and i own a similar one and
i was just curious if you get a lot of spam remarks?
If so how do you reduce it, any plugin or anything
you can suggest? I get so much lately it's driving me crazy so any help is very much
appreciated.

Public comment presented during the December 13, 2023 Engagement Panel Meeting:

Good evening.· My name is
Dolores Howard, D-o-l-o-r-e-s H-o-w-a-r-d.· I'm a resident of
San Luis Obispo County, speaking on behalf of the Santa Lucia
Chapter of the Sierra Club.
· · · · ·California produces enough renewable energy to
replace the Diablo Canyon nuclear power plant, and therefore,
the plant should be shut down -- excuse me, because my phone
slipped away from me here.
· · · · ·The risks posed by the storage of additional nuclear
waste are significant and unnecessary.
· · · · ·It is the legacy of waste that threatens our planet
and will continue to do so for countless future generations.
· · · · ·In addition to the issues with the storage of nuclear
waste, the potential weld embrittlement of the reactor vessels
is a peril waiting to happen.
· · · · ·UC Berkeley Nuclear Engineering Professor,
Digby McDonald, a long-time nuclear industry advocate,
recently co-wrote a report on unit one concluding while
regulators required PG&E to install samples of welded material
inside the plant, the effort to determine the condition of a
weld has stalled for the last 20 years, and there are
problematic issues with the testing program itself.
· · · · ·Do not extend the Diablo Canyon life.· Thank you.

Public comment presented during the December 13, 2023 Engagement Panel Meeting:

Yes, Jane Swanson, S-w-a-n-s-o-n, a
long-time member -- I live in San Luis Obispo, a long-time
member of Mothers for Peace.· I have several comments.
· · · · ·First of all, the running of this meeting has been
really excellent.· There's strong opinions, and they're not
all aligned up, but everybody is extremely civil.· So good,
good for us.· That's SLO.
· · · · ·I also would like to endorse every word that
Dolores Howard said.
· · · · ·And our prior speaker mentioned the workers of Diablo
Canyon, and how he's met them and all seem like good people.
Mothers For Peace couldn't agree more.· We're very, very
opposed to nuclear power.· We're very, very opposed to a
nuclear power plant built on earthquake faults, but we do not
consider that the people that work at Diablo Canyon to be bad
people or the enemy or anything like that.· We're grateful to
them for working as hard and with careful integrity to
that can be done to try to keep that plant safe.
· · · · ·The dangers to the plant could come from many
sources.· There was an earthquake there, but there was
earthquake very, very near the Diablo Canyon plant.· I
know where it came from, but I saw USGS report that it
December 6th, so just a very short time ago.· It was a do all an don't was small quake, nothing bad happened, but it just emphasizes, yes, it's
an active earthquake fault.· It's not something from a long
time ago.· And you can't predict what happens next, so the
earthquake danger is for real.
· · · · ·Regarding spent fuel storage, comments were made
about how -- concerns about equity on scene, generational
equity.· I -- I took a few notes.· It was said, nuclear
communities did not give consent to house nuclear fuel long
term.
· · · · ·Well, I lived in San Luis Obispo before there was a
Diablo Canyon nuclear power plant.· I was not asked to give
consent to have my community host a nuclear power plant that
would produce waste that would be around for lord knows how
long.· So I mean, it -- if you're going to talk about fair
consent and equity and concern for everybody, start at the
beginning, not in the middle.· I mean, the problems are very
real about equity right now.· I'm not disagreeing with that,
but the root of it went back before PG&E applied to the NRC
for permission to build a nuclear plant here.· And it went on
from there when the NRC gave them the construction license
even though it was already known that there were active
earthquake faults right here.· So the problem goes way back
prior what we're talking about now as the storage after the
plant is decommissioned.· That's phase 3.· We never dealt with
phase 1.
· · · · ·Thank you very much.

Public comment presented during the December 13, 2023 Engagement Panel Meeting:

Yes.· Marty Brown, B-r-o-w-n.
· · · · ·There are so many reasons to say no to PG&E's license
extension; enrollment of containment domes, seismic
vulnerability, radioactive waste with no finality in its
toxicity, nor ethical repository site, blocking safer
alternatives from being transmitting harm to the ocean life
with once-through cooling, and of course, the $6 billion price
tag to repairs.· It is our moral and fiscal obligation to say
no to PG&E's license extension.
· · · · ·Thank you for listening.
