Public comment presented during April 20, 2022 Engagement Panel Meeting:

KAYLENE WALKER:· Hi.· Kaylene Walker.· I live
20 miles from San Onofre, and I carefully followed the
whole Holtec fuel loading process and the multiple
problems and then the information that was discovered
from the various problems like a canister was broken,
shims was loaded, and the near drop, of course.
· · · · ·I did more than listen to the talking points
from the -- the public talking points.· I read technical
documents.· I attended NRC meetings.· So I would like --
· · · · ·And I would like to just call your attention to
some kind of misleading statements that I think are
worth looking into.
· · · · ·Number one, the inspection of the -- these
canisters are problems with corrosion and cracking;
that's -- that's an expected fact about these canisters.
· · · · ·The inspection technique is not an inspection.
That isn't -- the inspection report made a clarification
that this was a visual assessment.
· · · · ·That would be like going to the dentist and
having them take pictures of your teeth with that
camera.· They cannot assess the microscopic crack
development that happens with these canisters.
· · · · ·Visual assessments are not effective at
assessing crack development.· They can look at
precursors but not actual cracks.· That's a very serious
· · · · ·The repair technology that you mentioned that
San Onofre has been touting, that is ASME -- I mean EPRI
put out to the court in 2021 that said this nickel-spray
repair technology cannot -- there's no credit -- no
credit should be taken for structural or strength
properties of cold spray.
· · · · ·ZEKE TURLEY, AGP:· That's time.
· · · · ·KAYLENE WALKER:· Also -- is my time up?
· · · · ·MR. ANDERS:· Your two minutes are up.
· · · · ·KAYLENE WALKER:· Let me finish that one point.
The cold spray will not stop a helium leak from a crack.
That is like a very serious problem.
· · · · ·Anyway, I have so many points that I would like
to make.· Maybe I will put them in writing.· Thank you.

Public comment presented during April 20, 2022 Engagement Panel Meeting:

BRUCE SETTERS:· Thank you.· I have a couple of
questions.· I guess I just want to ask three or four
questions and hope the right person stands up and
responds to each one; so I am not sure exactly who to
address them to.
· · · · ·There was mention of some of the assemblies
that need to be loaded into the new cask systems having
been damaged.· I am just curious about a little bit more
detail about what that damage entailed.
· · · · ·There was apparently a failure on the part of
the prior contractor to load the proper pattern of hot
and cool assemblies into the casks, and that seems to me
to be a grievous error, and I would like to hear a
little bit about how that kind failure mode might be
mitigated and if there's checks and double checks and
it's not one guy looking at the plan.
· · · · ·How is the 4.2 kilowatt heat level determined
to be the safe threshold?· I understand the 50 kilowatt
total heat level of the assembly or the cask is
considered to be kind of the maximum threshold.
· · · · ·A question was asked of the engineer involved,
like, what's the worst thing that can happen?· And he
basically gave a fairly general answer that bad things
happen.· I would like a little bit more specific answer
about what those bad things might be.
· · · · ·And, you know, why would we risk accelerating
the schedule by a year, let's say.· I mean, I understand
there is money to be saved.· That's good for
everybody -- the diversified uses and repurposing can be
accelerated, et cetera.· But why would we not just give
a greater margin of error to adding another year?
· · · · ·To me, I personally have no emotional
investments in having this be a showcase of how fast we
can do it, you know.
· · · · ·So to me it's like -- I don't want to break a
world record in that category; so explain a little bit
more about what the cost tradeoff is
there.· Just slowing down the speed a little, if that's
possible.· Thank you.

Public comment presented during April 20, 2022 Engagement Panel Meeting:

KAYLENE WALKER:· Hi.· Kaylene Walker,
W-a-l-k-e-r.· (Indiscernible.)· I am familiar with
San Onofre, Holtec, and Orano system.· A couple of
questions.· I will just rapid fire the questions, and
then you can answer them as you will.
· · · · ·You said that the consideration of embedded
carbon parcels in a canister is not an issue of concern.
I think that should be looked into.· That would break
through a very thin chromium layer and potentially
create a pit corrosion problem.· I think it's worthwhile
looking at that.
· · · · ·Question:· Has your repair technology been
evaluated or approved by the NRC or ASME?· At
San Onofre, Holtec presented the repair technology, but
we found out then later that it had not been evaluated
or approved by NRC or ASME.
· · · · ·At San Onofre Orano got an exemption from
taking radiation readings at the outlet air vent.· Will
the outlet air vent radiation readings be gotten at this
· · · · ·A note to verify.· Cracked canisters have no
seismic rating.· Orano, I think in one of your slides
you claimed fuel retrievability.
· · · · ·I am wondering, do you actually mean fuel
retrievability or if this is an alternative definition
as in NRC's ISG 2, Revision 2, where they defended a
canister retrievability?
· · · · ·I am wondering what your fuel inspection method
is.· If you just do a video camera or if you actually do
a vacuum can sipping or in-mast sipping.· Is it -- you
know, what is your fuel inspection?· With a 50 kilowatt
heat load, that is a frightening heat load.
· · · · ·That is almost double the 30 kilowatt heat load
at San Onofre, and that is alarming for the problem that
could incur with the fuel, which is what we are storing,
the fuel could be (indiscernible) -- high-pressure
· · · · ·In the unlikely event of a canister failure, my
question is, Orano, do you plan to put a canister into a
overpacked cask? And if that is your plan, has
that been evaluated or approved or requested for
approval from the NRC.· Thank you very much.
· · · · ·MR. ANDERS:· Thank you.
· · · · ·KAYLENE WALKER:· These are serious questions
that the community -- those are serious questions that I
believe the community should be aware of these kind of
issues.· Thank you.

Public comment presented during April 20, 2022 Engagement Panel Meeting:

SHARON HAMMOND:· Thank you.· Hello.· My name is
Sharon Hammond, H-a-m-m-o-n-d; and I am with an
organization called the "Society Library," and we
organize collective information around a given topic and
then organize that information into debate maps for
educational and public consumption.
· · · · ·And from that regard I have to give absolute
gratitude to the panel and to the safety counsel as well
for your fantastic organization and information
· · · · ·My question now is, given the recent OIG report
that called into question the efficacy of oversight,
and, particularly, the efficacy of existing inspections
of Diablo Canyon facilities and risk-significant
equipment, are there any plans to, say, preemptively do
additional internal inspections or in some way
communicate to the public that areas that may have been
overlooked or not inspected as carefully as we would
have hoped are getting that attention?
And, specifically, you know, those
risk-significant systems and spent fuel areas.· Are
there -- are there any plans to more aggressively
monitor, inspect, and communicate that to the public
· · · · ·MR. ANDERS:· Anyone, can you address that? I
guess that's it.
· · · · ·Go ahead, Philippe.
· · · · ·PHILIPPE SOENEN:· There seems to be a lot of
focus on operational activity.· For the topic here we
are talking about our dry cask storage systems, and as
we talked about the seismic design for the -- our
current system and then there will be presentation for
the new system that will be implemented, I think we will
take note of what the comment as far as they relate to
the OIG and operational inspections.

Public comment presented during April 20, 2022 Engagement Panel Meeting:

Dylan Canterbury Baker.· I am an actual resident of SLO
County.· I live about seven miles from Diablo Canyon.
· · · · ·And one thing I have been very interested in
hearing is what are you also doing to address the
increased risk of seismic activity here?· Because, I
mean, now, in foresight we'd find it odd to build a
nuclear plant here in such a volatile zone.
· · · · ·And considering the storage is on-site is
unlikely to change for awhile, how is that going to be
addressed in the equation of keeping the nuclear waste
safely stored.· Thank you.
· · · · ·MR. ANDERS:· Okay.· We got the question.· Is
there anything else?
· · · · ·DYLAN CANTERBURY BAKER:· Just I am eager to
hear what you all have to say about this because I know
it's a concern of many people who live in SLO County and
live near it, and I go near Diablo Canyon pretty
frequently because I live in Avila Bay.
· · · · ·MR. ANDERS:· Okay.· Thank you very much for
your comment.
· · · · ·KARA WOODRUFF:· Chuck.
MR. ANDERS:· Yes, Kara.
· · · · ·KARA WOODRUFF:· Can Philippe give a brief
answer just on the seismic, like the bolting, and
maybe -- I guess we will be talking about the new casks
later in the evening --
· · · · ·PHILIPPE SOENEN:· Yeah.
· · · · ·KARA WOODRUFF:· -- but I think his question
also concerns existing casks.· Maybe you can do a brief
explanation on the seismic protections there.
· · · · ·PHILIPPE SOENEN:· So our system itself, I
should mention, would be we do have a modified
HI-STORM 100, it's seismically anchored.· They have
anchorage studs that go over 7 feet into the concrete,
and there's 16 of these studs around the base to prevent
any tip over.
· · · · ·The Nuclear Regulatory Commission looked at
those analyses and postulated a specter for our seismic
at the ISFSI.· Similar bedrock as the power plant is
built on.
· · · · ·So those were all analyzed and approved by the
Nuclear Regulatory Commission for the -- being able to
withstand, with margin, any seismic events that would
happen at the site.
· · · · ·KARA WOODRUFF:· Thank you.
· · · · ·MR. ANDERS:· Thank you, Philippe.· Thank you,

MARY MATAKOVICH:· Thank you.· Good evening.
It's been a very informative evening for me, and I
appreciate the opportunity to address you.· My name is
Mary Matakovich, M-a-t-a-k-o-v-i-c-h.· I am a resident
of Avila Beach, as well as I serve as a Port San Luis
Harbor District commissioner and as a liaison to our
Avila Valley Advisory Council.
· · · · ·So I'm representing the Avila Valley Advisory
Council tonight by emphasizing the letter that we have
sent you on April 11th, and I hope you have all read it.
But I would like to say a few words about our letter.
The Avila Valley Advisory Council has
appreciated representation of Avila, Avila's interest on
the decommissioning panel, and our council member,
Sherri Danoff has been instrumental in keeping us
· · · · ·Time after time we get reports, and she updates
us on what's going on with this panel.· It's very
impressive, and we need it translated sometimes into
just kind of basic -- basic facts.
· · · · ·And if I could give you an example of her
approach with us, you know, we share our concerns.· She
explains a little bit more about what the work of the
panel is and then addresses our questions.
· · · · ·And Sherri has been very instrumental now in
the intended to decision to barge the majority of the
waste materials from Diablo instead of the 70,000 truck
trips through tiny Avila on our narrow winding road.
· · · · ·Despite that Avila is the community, which has
the most -- will be most effected by commissioning
activities and also storage of used fuel in the future.
Whoops.· Am I out of time?
· · · · ·We ask you to -- we ask you to assure the
continued representation of Avila's interest on the
panel.· Avila Valley Advisory Council asks that an
ex officio position be placed on the panel and be
established with Sherri Danoff who has served in this capacity.
· · · · ·Please, Avila needs to have an experienced
representative on the panel, and we thank you for your

I am writing to inquire whether the DCDEP participated in the Department of Energy’s request for information re: “Using Consent-Based siting Process to Identify Federal Interim Storage Facilities’ and associated questions.”

I mention this because the subject has been raised at DCDEP meetings, and the questions regarding when the DOE will accept the high level radioactive waste does affect the schedule and cost of the decommissioning process.

The overall issue is found at the DCDEP website:


Prospects for Completion

This leaves all nuclear power plants in the US without any designated long-term federal disposal site. As a result, most nuclear power plants, including DCPP, must store their spent nuclear fuel, indefinitely, on site in dry cask storage systems made of steel and concrete casks. The prospects for completion of Yucca Mountain Nuclear Waste Repository or any other such permanent repository in the near future are low and there is currently no approved funding for further development. However, there was a Bill in the last Congress (the Nuclear Waste Policy Amendment Act of 2017) that directs the DOE to develop a federal Consolidated Interim Storage Facility (CISF) to be used until the development, construction and operation of a permanent federal nuclear waste repository is developed. That bill (HR 3053), passed the House of Representatives by 370 – 72, but Senator Heller (R- NV) prevented it from coming to a vote in the Senate. Senator Heller has since lost his seat. A similar Bill could be introduced in the current Congress.

It has come to my attention that at least one other decommissioning advisory board, that of the Vermont Yankee Nuclear Power Plant, had taken it upon themselves to provide public comment on this topic, and placed their letter on their website. I am attaching it. Had participating in this public comment opportunity been discussed by the DCDEP? Where the members made aware of it, collectively or individually? It would seem that comments from communities immediately impacted by decommissioning would have a significant voice in the process as they will be the first to be left with the waste (long before the majority of the reactor sites that have received 20 year license renewals from the NRC).

I am attaching the Vermont letter. Although the deadline has passed, the DOE website does indicate that subsequent comments can be sent, they are not guaranteeing that late arrivals will be reflected in their final report. Thus, an opportunity remains should the DCDEP wish to engage.

I will also post this to the public comment section of the DCDEP website.

Thank you for the opportunity to bring this to yours and the committees attention.

Yours truly,

I would be interested in a modern Sanitarium on 50 acres for the mentally ill. Young people are surprised when I tell them that not so long ago we did not have people live on the streets and beg for money on street corners. loitering and panhandling were illegal. The mentally ill were placed in sanitariums. Sanitariums did have some problems but we could try again and do better. Nursing homes have problems but we do not turn seniors out into the streets. The State giving local government money to solve the problems is not working. Nobody is happy with the homeless situation so why not give a small portion of serene land and try a new direction.

February 22, 2022Economic Impacts

With all of the powere shortages California has , they will only continue to increase one by closing diablo, but two by the increasing needs for electricity as more and more electric cars, all electric homes and businesses come on line. Until much more alternative power sources are built, not just planned, Diablo should remain operating. One other topic that gets very little, if any attention, is the ability of Diablo to desalinate ocean water. The plants ability to do this can be expanded at a time when our super drought is predicted to continue for years! Please lets keep this plant operating at least until we have replacement power in place instead of closing it to make some feel good. It does fit California’s green agenda for the near future.

Dear Diablo Canyon Decommissioning Engagement Panel members and San Luis Obispo community members,

I am Tyson Chen. I am a Cal Poly student and I am writing as a new resident of San Luis Obispo. Before coming here, I have heard nothing but good things about this town, especially about how beautiful, temperate, and natural the SLO environment is. I traveled here with skepticism and modest hopes. But after living here for several months, this town’s climate and environment resembled nothing short of a paradise. Every major environmental decision should be made with careful consideration to preserve the beauty of this town and its surroundings.
While it’s good that SLO and the rest of California are transitioning to nuclear power and renewable energy, decommissioning Diablo Canyon and other nuclear power plants is not an environmentally feasible idea and could incur large costs to the environment and destabilize the energy supply.

In response to the closure of Diablo Canyon, Gavin Newsom, the then-lieutenant governor of California expresses his concerns over the loss of nuclear power in California and its impact on the environment: “The sudden closure of [nuclear plant] San Onofre... lead to significant greenhouse gas emissions... highlighted my concerns around Diablo” (Cardwell). Natural gas and fossil fuel production must ramp up to cover the lost power from decommissioned nuclear plants, in turn causing a rise in greenhouse gases and air pollution. So far, the air in San Luis Obispo is clean, clear, and rejuvenating. I hope not to witness the same deadly and depressing smog that afflicted my hometown to be seen here in SLO. I do not want to be locked indoors because the air outside is too polluted to breathe, and I dread the possibility that the snow-white morning mist and fog turn into a toxic brown haze.

California’s general strategy to replace the power generated by nuclear plants is to install renewable energy production infrastructure, such as solar cells and windmills. Scientists performed a case study in Sweden projecting the environmental costs of replacing nuclear energy with renewables. The study concluded that such a scenario would increase greenhouse gas emissions (Hong et. al 1). This is not only caused by the increases in natural gas and fossil fuel production, but a substantial amount of greenhouse gases would be released from producing new infrastructure. In fact, nuclear power generates around 570 and 4000 times more energy for the same area of land compared to solar and wind energy respectively (Smil). Right now, Diablo Canyon plant only takes up land for one large structure. Imagine covering the lush hills and the natural, undisturbed land of SLO with solar farms and windmills just to cover up the power generated by one nuclear plant. Such a decision would disrupt the lovely landscape that the Central Coast is best known for and eliminate a source of clean, stable electricity.

As California shuts down Diablo Canyon, the state’s last nuclear plant, I question the wisdom of this pivotal decision. As end users of technology, the way we consume electricity in our everyday lives will remain the same, but what becomes our primary source of energy will affect us all; it will affect the availability and stability of our electricity, and the environmental impacts of the source of power will affect our future environment, our health, and our quality of life. All I ask of the panel and fellow residents is to reconsider nuclear power as a feasible source of energy for the future. Thank you!

Hello. There is a tremendous push by some who are advocating for the continued operation of Diablo (which I vehemently oppose). I have also heard a rumor that PG&E is in behind-closed-doors conversations / negotiations with investors will to take this on. I would like to know if there is any truth to this. Is the Panel wasting its time? Is PG&E planning to renege on its agreement to close in 2024 and 2025?

I would like an official response from PG&E. Thank you.

November 11, 2021Repurposing of Facilities

The chosen "hybrid mode" of decommissioning in my opinion is basically bad, bad for anyone who cares for that land....but it's good for bean corners at pg&e HQ in San Francisco.

I've been involved in way too many large construction jobs and I know how this goes.... PG&E takes on the role of a General Contractor(GC) and they put "everything" out to bid (getting subcontractors).... they contract the "lowest bidder", PERIOD...... Any responsibility is contractually conveyed to the subcontractor(lowest-bidder)...... You can see that I didn't want to get in-the-face of Erik Daniels over this reality of construction (which I'm sure he knows).....and the SF HQ has specificaly selected decades ago.

In my opinion ,this mode is even worse than the last two listed inthat in that it allows PG&E to hire subs who are not licensed in the nuclear industry.

Re labor: the General Contractor never gets to tell the sub who the sub is going to hire, unless...... there is a negotiated labor contract in place such as with Union negotiations.

I think you have a history with the plant I need to make it clear that I think all the people at the Diablo site are extremely well-intended, salt-of-the-earth people who have made a home in San Luis Obispo County... Again, to be very clear the group of people who are up at San Francisco HQ for pg&e are mostly accountants and lawyers...... Frankly, they view us like a bunch of expendable hillbillies..... and to make no mistake about it, the bean-counters at the SF ,HQ call all the shots . In my opinion

Public comment presented during November 3, 2021 Engagement Panel Meeting:

MR. BROWN:· All right.· I guess I'm muted.· Well, listen, as a former member the Diablo Canyon Decommissioning Engagement Panel I took particular pleasure in listening to Tom Jones' report on how PG&E has incorporated guidance from the panel into to their planning.· It's extensive.· And for me it's very gratifying to see that.
I'd like to assert the following point:· These positions from the panel just didn't come from the minds of the panel members.· It was a result of an extensive engagement with the public, of conducting multiple public hearings, taking input from the public and incorporating that into the thinking about our recommendations.· And I would just like to encourage the public to continue that process.· We're a long way from finishing this.· And also to compliment PG&E for creating the process in the first place and really paying attention.· So thank you very much.

MR. BROWN: Good evening, panel.· My name is Ben Brown, San Luis Obispo.· I had a comment and a related question.
My comment is:· I'm very concerned about the removal of this large amount of baseload clean power that's local to our area, especially in light of the COP26 Conference that's going on right now as we all race to reduce carbon emissions in our grids.
My question is: What are plans by PG&E to provide a similar level of clean baseload power for the Central Coast after the removal of the Diablo Canyon asset?
Thank you.

MR. GREENING:· Okay. Very good.· Thank you.· This is Eric Greening.· Thank you for that presentation.· I'm going to have more comments relative to the county process and the EIR process.
But my comment right now is simply a suggestion for a future meeting topic and presenters for it. And that would be to invite someone from one or both of the utilities active with the San Onofre Decommissioning. And then sort of for another view from a different angle of that process invite someone from the Samuel Lawrence Foundation and get a feeling and learn what we can from the experience of the utility that is several years ahead of us on a track that is at least parallel to and may have some resemblance to the tracks that we're going to be on here. And, hopefully, we can learn from missteps as well as successes.
And so, again, I would say don't do it without having the balance. In other words, have someone from one or the other of the utilities involved and havesomeone from the Samuel Lawrence Foundation so that we get a range of points of view on the experience and lessons to be learned there.
And I'm thankful for the opportunity to engage on agenda items as we go along. Thank you.

MR. KRASNER:· Hi there, everybody on the panel. Thank you for this opportunity.
I live in Pismo Beach.· And my questions are going to be focused on the Pismo Beach Rail Yard and rail transfer construction.· In a recent notice in one of the local papers it indicates there are three additional locations for potential rail transfer sites, one of which is the Pismo Beach Materials Handling Facility on Price Canyon Road.· Has that facility gone through CEQA and the EIR requirements to be approved?· That's one question.
I do see that a company in San Luis Obispo by the name of Precision Estimating Services has already built out 20,000 square foot hazardous waste transfer building, installed 3100 feet of new track and done some significant upgrades on roadways and traffic signals.
This facility is very close to a middle school and also quite close to residential properties.· So I am alarmed by the location and the potential for problems. And want to know what has been done to mitigate such problems as they could come up.· Thank you.

Public comment presented during November 3, 2021 Engagement Panel Meeting:

MS. HARVEY:· Thank you.· I appreciate the·opportunity. So Susan Harvey. I'm in the county near Paso Robles. And I'm commenting on behalf of the Santa Lucia Chapter of the Sierra Club. And I have a couple of questions.
·When you refer to the intermodal containers I'm wondering if they will be sealed in waterproof -- in water tight while they are being transported.
So Susan Harvey.· I'm in the county near And I'm commenting on behalf of the Santa of the Sierra Club.· And I have a couple.
And then my next question is:· The permitting for the use of the port for barging, will that permit be exclusively for and by decommissioning through 2039?· In other words, will that be the only activity that is being permitted at that port site until 2039?
MR. JONES:· ·Yeah.· So your first question the simple answer is yes.· They are watertight and they are sealed.· They are robust shipping containers.
The second question:· Will that be the only ·activity?· No.· We currently run boats out of there for a marine monitoring program.· And then prior to 9-11 the -- we -- it was a harbor of safe refuge.· And so it was common to see three or four maybe five fishing vessels·just come in our harbor and take anchors during the night or the morning, and then go back out and start fishing.· So that use could occur independent of this activity.
What we're trying to do is -- part of our Environmental Impact Report bounds the impacts from that 10· ·process, including the shipping and transportation.
Secondarily, because we would be conducting some construction in the original jurisdiction area that will be subject to the California Coastal Commission to ·approve that modification as it will also be part of a new lease with the California State Lands Commission. So, again, the county leading the Environmental Impact Report, that document is going to serve all three of those processes.· So the county has the lead in the analysis and coordinates with those other agencies about what level of detail they will require.
So to take that one step further.· When we make our application for the lease with California State Lands Commission there's different levels of engineering diagrams and design.· And we'll be at what's called the 30 percent level.· So we'll have more than a conceptual design of how that structure will be modified to accommodate barging kind of transportation.
Now, if you think repurposing and succession, anything that can launch -- you know, that can successfully convey a 25-ton container onto a barge 100 feet out can certainly launch any recreational vessel into the water.· So the opportunities there will be beyond what's in the application.
MR. ANDERS:· Thank you, Susan.· Did that answer your questions?
MS. HARVEY:· Yeah.· Thanks.· I guess.· I think I'm not quite sure what all my questions are.· But thank you very much.

Public comment presented during November 3, 2021 Engagement Panel Meeting:

MR. GREENING:· Thank you.· I just wanted to get some clarification.· I thought I heard that the panel was going to have a field trip to San Onofre, is that correct, where you'll physically actually be touring the facilities there?
And my question is:· Is that going to be a public meeting in any way?· Either that we would be able to be present virtually or that people would be present on the·site physically?
And, again, I have the concern that being on a tour only with the utility operator gives you certainly a large part of the picture.· But you don't have a complete picture unless the public is also able to participate and speak to you.· And, particularly, I would assume people in the Samuel Lawrence Foundation 10· ·would be very interested in participating and having their concerns heard.· It might provide some lessons for us in terms of things to avoid.
So tell -- if you can explain more about the circumstances, the meeting, and its openness to the public and whether the proceedings of that meeting will somehow be available to the public after it has happened.· Thank you.
MR. JONES:· ·Chuck, I can address that.· This is Tom Jones.· So no, it is not open to the public.· It's an intense tour of the physical decommissioning of the power plant.· So everyone will be wearing personal protective equipment.· They will be escorted by experts from Southern California Edison.· And a pretty hazardous industrial environment.· So it's not going to be a public meeting.· And it is by invitation to their private property.
I will say that the panel will clearly get an update.· And they do trip reports.· So the panel has benchmarks; San Onofre.· It's traveled to Rancho Seco in the past and offered those updates to the public for what they have seen with regard to the -- any entity, whether it's Samuel Lawrence or anyone else, the panel is free to invite who they wish when we build out an agenda for a meeting.
MR. GREENING:· ·Thank you.· So I will repeat the comment from earlier in the meeting that I think that the Samuel Lawrence Foundation should be invited to a future meeting, one of your regular public meetings as well as the utility itself to kind of give their perspective as well as the utility's perspective on lessons that we can take with us in terms of our own experience that is happening in ensuing years that they have been through already.· Thank you so much.

Public comment presented during November 3, 2021 Engagement Panel Meeting:

MR. GREENING:· ·Thank you.· First I'd like to second Scott Lathrop's comments.· Thanks to the Commission for hearing and taking in all of the public comment and to PG&E for making an effort to take a lot 20·a lot of those recommendations by ways to implement them.
I do have two questions.· One relative to the approval process on the casks by the NRC.· There is a public comment period in that process.· And my question on that is simply:· What consequence those public comments have?· Can they actually lead to some -- to changes in the project description to mitigation measures?
And then my second question -- and I want to be sure that Susan is on the same page with Tom with this. We saw what looked to me to be a very rushed schedule for approval.· If both the Planning Commission and the Supervisors are to approve this project by the end of 2022 there's normally at least two months between a Planning Commission action and a Supervisors' Appeal Hearing.· So that would be Planning Commission in October.· That's 11 months from now.· That presumes a completed final EIR with a 60-day comment period between the draft and the final.· That simply looks like an extremely rushed EIR process considering all that it has to look at.· That would, basically, put a draft EIR out in June, six months after the scoping period is done.
I would assert that what we most need from the EIR process is not speed but thoroughness.· And I don't see a -- how a schedule that presupposes a completed EIR -- final EIR by October can accommodate the needed thoroughness.
So, Tom -- I don't want to put Susan on the spot. I know this isn't your segment.· But I would like to know that Tom and Susan are on the same page with this. Thank you.
MR. JONES:· ·We're on the same chapter, I don't know we're on the same page, Eric.· And I tell you this. I think Susan was clear in her update earlier that -- that the county intends to publish its schedule for this process that's been revised around the scoping period. So I would say stay tuned for a couple of weeks and we'll hear more from the county on that schedule.
Our schedule doesn't change, though.· It assumes a pessimistic hearing.· We did build it off of our previous ads through the county and coastal processer. And at the end of the day we still look for that final approval three years from now, the California Coastal Commission.· And that's actually a longer schedule than our other projects have had.
To your first question, I really think there is a ·complaining or a combination of a couple different processes.· So the Nuclear Regulatory Commission will have a licensing action on the safety of the casks. It's federally preempted.· And that will be their exclusive jurisdiction.· That process will mean a licensing action.· But the land use and CEQA process for the construction of dry cask storage was for the entire project, for the loading of up to 138 casks for fuel at that site in all seven pads in perpetuity.· So that action before the County Board of Supervisors and Coastal Commission won't come back.· So for the future ·of dry cask storage it's a licensing action.
Then to your last point.· Does the NRC take public comment into account?· Yes, they do.· And there's multiple ways.· One, there is just straight public comment like people do at a hearing or a meeting like this.· And the second is they also have their own intervention process where people can achieve standing and participate in the licensing action.
So all of those things are run by the NRC not the utility.· I'm just familiar with them.· But that's laid out on the NRC's website as well.
MR. GREENING:· Thank you for clarifying that. And, again, I -- I will continue to advocate for thoroughness over speed when it comes to environmental review.

November 3, 2021Other

Public comment presented during November 3, 2021 Engagement Panel Meeting:

MR. GREENING:· Thank you.· I'm Eric Greening. I live in the North County.· And I think the reason people are calling Susan "Sharon" is because she's sharin' so much important information.
But, anyway, I do have a question that -- I guess the timeline is still a little bit mysterious on the EIR.· But I have a concern to raise about that timeline in reference to something I brought up at the County Supervisors yesterday when -- when Susan was giving a progress report, which is that a very important increment of this project is the casks and how they will be handled.· And we don't yet know what that will look like.
And I was, essentially, defending the need of the EIR to provide full analysis and mitigation of the hazards thereof, even though the county doesn't have control over that particular increment of the project; for the same reason, for example, that it needs look at hazards and mitigations of those hazards relative to things like earthquakes, even though it has no control over the placement of faults or the timing or intensity of earthquakes.
So in any event, my concern is the -- the consultants were given a budget which presumes a certain workload and a certain timeline.· And I would just like to hope that whatever it takes to fully understand the casks and how they will be handled, and, how they be handled in the event of a need to replace one, et cetera, et cetera, so that mitigation measures be developed as needed once the hazards are fully understood that we not rush this thing ahead of a understanding thereof.
And then the only other thing -- and I'm going to bring these up during scoping too.· This morning I was at a very sobering global meeting relative to Fukushima and the plan to hemorrhage 860 trillion becquerels worth of radioactive water into the Pacific.· I can see a nexus for monitoring -- careful monitoring not only relative to Fukushima as a kind of a nexus for hazards we endure here generated locally, but also perhaps to catch local -- anything that locally gets into the ocean.
Currently, the Mothers for Peace sample ocean water and send it to Whit's Hole (phonetic).· And it has detected spikes from Fukushima's cesium.· But what we do not have and, apparently, don't have anywhere along the coast of -- of the U.S. is monitoring up the food chain. Concentrations in the sea water are one thing, but concentration in sea life, especially as you get toward the upper end of the food chain pyramid can be quite a bio concentrated other thing.
And so I would just like to put out there the possibility that we look at a program.· And, presumably, the different isotopes we could identify what might come from a Diablo Decommissioning operation versus what might have come from Fukushima.· But we definitely need to be gathering information about both.· Thank you very much.

Public comment presented during November 3, 2021 Engagement Panel Meeting:

MS. HARVEY:· Can you hear me now?· There I go. Thank you.· Thank you for the opportunity to comment. I'm wondering about Phase III and scoping comments and the county's analysis of reuse.· Does that apply only to Parcel P?· The EIR is only looking at Parcel P; ·6· ·is that correct?
MS. STRACHAN:· That's correct.· It's just Parcel P.· So the reuse options would be limited to Parcel P.
MS. HARVEY:· Okay.· Would the -- nothing in the EIR, then, would necessarily be looking at what opportunities there are for mitigating impacts with surrounding properties that PG&E owns?
MS. STRACHAN:· The -- the -- it would look at impacts associated with decommissioning within Parcel P. If t here were a part of the project that would impact offsite -- so, for example, the rail site -- the rail loading facilities I mentioned, those are offsite.· So we will evaluate that.· But since the -- the project boundaries are limited to Parcel P that's where the focus is.
MS. HARVEY:· And you wouldn't -- I guess I didn't state that very well. Could there -- is there a potential for offsite mitigations for onsite impacts?
MS. STRACHAN:· You know, that's one that's too early to tell.· It's hard for me to make an answer on that right now since we're just getting started.
MS. HARVEY:· Thank you so much.
MS. STRACHAN:· Susan, I understand your question. But it depends on the impact.· It's hard to answer that.
MS. HARVEY:· Thank you.

MR. BROWN: Okay. Well, first of all, I'd like to thank the whole panel and the speakers for an excellent program tonight. I very enjoyed it. I really have a couple questions, no comments. The question I had, maybe a missed the content of the speakers from the California Energy Commission, but I'm wondering what is the timing for proposals to be received for the offshore wind?

My second question may be directed to Tom Jones. Knowing that one of the aspects of the offshore wind project that ties in with the decommissioning of Diablo is making use of the power distribution system and I'm wondering, Tom, have you received any feelers whatsoever from anybody, any potential wind farm operation about tapping into the distribution? That's all I had.

Public comment presented during August 25, 2021 Engagement Panel Meeting:

MR. GREENING: All right.· Thank you. Yes. Thank you. I'm Eric Greening and excellent presentations. Obviously, a lot of issues raised and I think the previous speaker hit on something. If there were to be a residential or resort used, I'm almost positive the county would require a secondary egress. We're not just talking about a secondary route through Avila. We're talking about a complete secondary egress from the site. That in itself would have a normal -- enormous environmental impacts creating that. Certainly, if it were no longer a roadless stretch of coast northward from there, that would have enormous impacts and so wildfire issues obviously evacuation issues from radiological and so on, there would have to be more than one way out if there were people actually living there.

Relative to the wind energy, my understanding is current blades are made of unrecyclable materials that become waste products. Would that be the case with these absolutely enormous blades? What would their life cycle be? What would their duration be? What would their destination be once they cease to be useful? And I would advocate that Cal Poly and all other potential research partners look into bladeless options for harvesting wind energy. I understand that there are some increasing possibilities out there and I don't think we should just assume the word wind means turbines. There's marbled murrelets and wedge-tailed shearwaters and other birds that would be knocked out of sky by these blades and I think -- Anyway, I think definitely the whole characterization of future uses, of course, depends on the site being safe and there's a lot of information we need. My understanding is the county has not yet accepted the application as complete and some of it has to do with waste characterization and handling. Do we have any idea when the scoping period will be on the county's EIR? If there's anyone from the county to answer that, I would be appreciative. Thank you.

Public comment presented during August 25, 2021 Engagement Panel Meeting:

MS. JOHNSON: Thank you so much to the panel, especially Larry and Patrick. I am very interested in maintaining the use of the desalinization plant. I own two properties in Carlsbad and I'm very familiar with that plant. We really do need to balance out the consideration of a seven-mile pipeline versus saltwater intrusion for highly valuable ag land in the area Huasna, Oceano. I think we need to preserve that extra water resource. Carlsbad is operated by Poseidon It's at no cost to the taxpayers and I think you could probably get vendors to operate and provide the water through the desal plant. I'm excited about that.

Also would like to see some extra camping and glamping in the area. That's a beautiful area and I think that would be a light touch and could afford a lot of enjoyment for that area.

So those are my two -- I think the panel has been wonderful, very informative and I'm excited about learning more about this as we go ahead, but I really hope that the desal plant is repurposed and continued and we continue to learn and refine and figure out howto power that resource. So thank you very much.

I'm the chair of the Conservation Committee of the Santa Lucia Chapter of the Sierra Club and first I'd like to say that we are very strongly committed to very local impact reuse of the Parcel P whether it be recreational or low impact research facilities.

My next thing, the idea of an industrial port somewhere on the California Coast sort of shredded my brain and I started wondering about the transmission potential of the lines coming out of Morro Bay, what that capacity was and the transmission capacity coming out of Diablo and do the Morro Bay lines and the Diablo lines feed into each other. I think that's really what I was really curious about, especially with the concept the onshore facility that might be needed for wind. Thank you.

MR. DOWNING:· My name is Matt Downing. I'm the community development director for the City of Pismo Beach. First of all, take the opportunity to thank everybody on the panel. It always makes me happy seeing my fellow community members participating in things like this. That really means something to the greater community. I've spoken to the group before about this process and we -- I just wanted to reiterate some of my comments. The desalinization option is great, but I will say that we do have our project, Central Coast Blue, that we are continuing to move forward with. Granted, it's hit some speed bumps as of late, but we are confident that we can work with our partner agencies to smooth all of that all out and that will provide us with the recycled water for our south county area that we need.

I think it would be a terrible waste to get rid of the marina. I know we've hinted at that in the past. So I'll just put a plug in there. Anything we can do to promote that marina would be a unique opportunity. Having some type of commercial use out there, theglamping idea is good, but as we know, anything with that large commercial draw is going to bring -- because of the remoteness that several of you spoke about is going to bring what it always brings and that's traffic. So really addressing the traffic issues, having one way in and one way out to that area currently is going to be the foremost for our community, as we do see vehicles back up onto our local roadways from large events out in Avila.· So just wanted to make those comments and thank you everybody for their time this evening and have a wonderful rest of the night.

Public comment presented during August 25, 2021 Engagement Panel Meeting:

MR. GILESPY: I've been a long-time resident in this area. I started fishing up here in 1970. I fished this coast offshore in the area of this composed development and know it very well and I'm also educated in oceanography and I'm concerned about the very interface with the water of the wind that normally would be transiting that area and the possibility of all the upwelling currents that drive the warm waters offshore and commence the prime production process of plankton and chlorophyl development and the basic process of growing food fish and just fish in general. This plant is 400 square miles. 200 of these gigantic windmills could have an effect on this extremely important aspect of the California coastline and especially at build-out if they went all the way up the coast. I can tell you when you interfere with the wind, the warm water comes in and mandates the area and it will also have a regional climate effect not only on the coastal communities, but as well as those inland and as well affect potential rain patterns and temperature patterns.

I guess I first got into this when I was looking for was there any study about this and I didn't see it. I had to get over the gag reflex of this grotesque development in this pristine ocean area and its potential effects could alter the very aspect of Ocean, which is a placid ocean that relies on wind patterns and wind to commence and continue at circulation. I don't know if I fell within that. I could probably go on, but thank you. This panel is very edifying and I appreciate their being part of it.

Public comment presented during August 25, 2021 Engagement Panel Meeting:

JANE SWANSON: Number one, given there are 750 acres in Parcel P and given that this meeting is about the repurposing of Parcel P, I was very surprised to hear the real estate consultant refer to -- I thought he referred to thousands of acres or did I misunderstand that? I may have a misunderstanding. So I thought clarification when he was talking about glamping and all these touristy things, is that within the 750 acres or is that beyond?

Second question. Yet to come in this meeting is PG&E's update of the new nuclear fuel storage system with discussion by panel members to follow. I don't see on the agenda that there is an opportunity for the public to ask questions following the panel discussion and I'm hoping there is. So I would like clarification on that. Will the public be able to ask questions or clarifications following that report?

September 21, 2021Repurposing of Facilities

Public comment presented during August 25, 2021 Engagement Panel Meeting:

MR. SHOULDERS: I have several comments. I'll be curt.

On the windmill issue, the 1920 Marina Act or the Jones Act requires the ships that would install these installations to be made in the U.S. and carried by U.S.-owned and crude vessels and there's no such huge ship that can install these devices in the United States at all and for the very small number of East Coast installations, they had to have a Dutch ship -- I think it was Dutch -- come to Canada to take all of the equipment and install it because there's no such ship in the United States. So I think when we talk about the feasibility of installing a few of these on the West Coast, we need to be aware of the fact there's no way to install it as I stated.

Secondly, on the desal issue, 18 months ago or two years ago, this panel had a long presentation by the engineer at Diablo Canyon that's in charge of the water and a representative of the south county organization that's responsible for water and that south county person said he had no interest whatsoever in taking Diablo desal water because of the cost issue and I'm surprised no one seems to be aware of that.

Thirdly, when we talk about the massive amount of renewable energy we need in this state to meet this goal that the state has put forth, and I listen to the galatial pace of accomplishing getting windmills approved, it doesn't support the kind of goal that the state has. You know, this is an existential climate change and we need to do a World War II kind of thing. So we need to cut through the bureaucracy. And, finally, the access road, I'm particularly familiar with the -- if you look at coming up the slope from the entrance, there's lots of slippage that's occurred over time and there's a massive threat there and an expense to keep that road open and that needs to be considered when we talk about using any installations further up north from the entrance point. I'm done.

Hello. I attended the August 25, 2021 Panel meeting regarding repurposing of Parcel P after decommissioning. I was quite horrified by the presentation by Richard Gollis from JLL. He relayed the "market assessment" of building a resort hotel, an RV park, marina, homes.... I don't know where he got his information, but this is NOT what the community wants. The DREAM Initiative of 2000 had support of 74.66% of the county voters to set aside the Diablo Canyon Lands for habitat preservation, agriculture, and public use upon closure of the plant. This Initiative was unanimously supported by the SLO Board of Supervisors, PG&E, and numerous community and environmental organizations. The Strategic Vision of the DCDEP based on community input confirms that the land be used for the common good. Parcel P, specifically, is to be used for educational purposes and production of clean energy.

Why are we shutting down California's main source of clean power? "Replacing it with solar and wind" is not realistic, as that capacity would be built anyway, and we could take the methane "natural" gas plants offline instead.

I know there will be a great deal of interest in designating this land Open Space and committing it to passive, cultural, and recreational use. And I support that, but with reservations. My concern is that we don't know what the future holds and should be careful to not preclude beneficial public uses of this property for what are now unforeseen future needs. This land may be needed for public energy uses or other public infrastructure uses in the future. Any designations or entitlements placed on the land should be subordinate to and subject to future 'public domain' or 'utility' or 'public infrastructure' uses. Thank you for keeping this in mind.

Please pursue extending the license for this reactor, is it desperately needed to achieve our Carbon Reduction goals. I have heard recently CA is adding more Gas power to prevent Black Outs, and this will only get worse without Diablo Canyon online. We should learn from Germany who tried to increase their renewable power while also decommissioning their reactors, and are now dependent on Coal and Russian Gas to fill the gaps when renewables aren't able to produce. We need clean baseload power that is not weather dependent.

August 25, 2021Repurposing of Facilities

I would like to propose that as part of the planned future decommissioning of Diablo Canyon Power Plant, the board consider converting the artificially protected open ocean area where Diablo takes in their coolant water, that the area be transitioned into a protected marine preserve which would allow recreational scuba divers the opportunity to swim and hike in that area (for a fee). I do not make this recommendation on a lightly. If you have ever been to Point Lobos in Carmel California you know they charge for entry/parking. They also charge for scuba dive teams, which they limit to 30 teams per day. The offer a limited number of dive team permits daily and they are often sold out weeks or months in advance, especially for weekends. Point Lobos is operated by the State Parks Department who also issue scuba diving passes via their website. Point Lobos charges $10 for parking per vehicle and another $30 for a dive team consisting of two divers (divers always use the buddy system). I do not know the max depth or contour profile of that specific area, but if it's more than 30' in some places, this could be a great means of both revenue and marketing for the state/county as well as an education tool for the California dive community. Scuba divers are a special breed of human being in that we always want to preserve the environment which we recreate and dive in. We are stewards of the ocean and the marine life contained within. We are guests, not residents. The ocean does not belong to us, yet we are responsible for its care and well being. I've been blessed to be part of the California Dive Community for the past six years, but unfortunately there are not many dive sites in our local area. I drive at least two hours North or South to reach a 'destination dive site'. Consider what it could do for the local San Luis Obispo Coastal community if we had a dive destination like none other on the West Coast right here in our local coastal waters.
