Hi Dave,<br>
<br>
Thanks for setting up the meeting. Maurizio is not on the RICH. We
can request Valery Kubarovsky, he is writing the OSP.<br>
<br>
Thanks,<br>

<div>Unfortunately changing the relief set pressure does
not necessarily mean that the system will be excepted
from the program. I have seen some incorrect information
moving in these e-mails. It would be best if we could
all sit down and formally decide what needs to be done
and map out all parts of the system. Wording like
downstream of the bottle must be determined by a DA are
not correct. Also there are no exempt systems. They are
either excluded or excepted.</div>

<div>I plan on replacing the 50 psi relief valve with a 15
psi relief. Then we will set the pressure regulator to
10 psi instead of 15 psi. I plan on making this change
to all the new N2 purge systems hall B.<br>
<br>
This is to exempt these systems IAW chapter 6151 of the
ES&H manual.<br>

<div>Perhaps you and I should meet with George, you
can then go into detail about what parts may need

<div>Hi Marc,</div>
<br>
<div>It seems that Patrizia is away from the
lab. I do not have an estimate for the time
this will take but it will be significant. I
am working on it nights and weekends to make
it happen. I don't know if I will make the
December review though. This system will have
to be tested and inspected which will not be a
trivial thing. Please note that the mixed
materials in the Swagelok fittings are not in
compliance with manufacturer's catalog/manuals
and may have to be replaced with brass
ferrules and copper tubing.</div>

<div>Hi Dave, Have you had a chance to
communicate with Patrizia on the RICH design
authority work? DSG management is trying to
prepare scheduling for the near future, so if
you have an estimate on the time required.
That would provide some valuable information.
