<p>Hi Dave,</p>
<p>I have read your response to the recommendation. Hall B has
identified a system owner (Bob Miller), so that issue is resolved.
I have also looked at your docushare folder (<span

<p>As I understand it, once the correct materials are purchased and
the piping is upgraded to reflect the changes...You and George
will have more technical data to begin pressure calculations for
relief valves. After that there will be some examinations,
leak/pressure tests, prior to turning the system over to the
owner. <br>

<p>If you don't mind, please send updates via the <a class="moz-txt-link-abbreviated" href="mailto:dsg-rich@jlab.org">dsg-rich@jlab.org</a>

<div>After talking with Patrizia and looking over the
recommendations from the last ERR, I have attached a response
to the ERR item number 4. In my opinion the OSP may be drafted
at any time but the system shall not be deemed safe to operate
until the system has been turned over to the system owner. The
owner needs to be identified clearly and this person must have
the required training SAF 103C which is being offered soon and
is classroom based. Note that JLAB design authorities do not
"approve" systems. This approval is a multi step process and
is described in ESH&Q manual Chapter 6151.</div>

<br>
The system will not be operated prior to approval. <br>
<br>
As far as I know, nothing has been approved and this process
is on hold until after the KPP. For more information, you will
need to direct your questions to Dave Meekins, he is the DA
for the RICH.<br>

George, <br>
my question is specifically related to the RICH
recommandation which <br>
reads: <br>
<br>
The air-cooling and nitrogen gas systems are pressure
systems and <br>
approvals from the Pressure Systems design authority are
required <br>
before operation. <br>
<br>
Forgive my ignorance: I am not sure WHEN the approval should
be <br>
granted. I assume in order to "modify the hardware" (as you
say) you <br>
need to follow a design (already) approved by an authority.
<br>
Do you actually mean the DESIGN is still being modified, to
get <br>
approval and then a new hardware layout conform to JLab
regulations ? <br>
Or there is already a new approved design and you are as a <br>
consequence working on the new hardware ? <br>
<br>
Thnaks, Marco. <br>

Dear George, <br>
thank you so much. I appreciate the manuals and
diagrams. Does it means the design is now approved (by the
pressure <br>
system Design Authority) or <br>
is this still in progress ? <br>
Thanks, Marco. <br>

I have attached the P&I diagrams along
with the operations manual for your OSP. The hardware is
being <br>
modified to comply with <br>
JLAB's pressure systems requirements. <br>
<br>
The EPICS screens and cRIO Controls Manual are
a separate entity. <br>

Dear David, Marc and George, <br>
Hall-B will undergo Accelerator
Readiness Review (ARR) next week. As part of this review,
it is <br>
required to answer to <br>
the recommendations of CLAS12 ERR. For
the RICH detector, they deal with the OSP. <br>
<br>
To my understanding, you had a meeting
in November to clarify the remaining issues about the RICH
<br>
pressure gas <br>
system. May you provide <br>
me with an update of the OSP status ? I
would need to send this <br>
information to Eugene Pasyuk within
today. <br>
<br>
Thank you a lot, Marco. <br>
