Dear Walt,

I will be attending the same Ready4Science review. Same for Maxime and 
Marco. The review should be done by 11:30 am. I am available after that. 
We already talked today with Marco and agreed that we could come up with 
a solution which would not require the CVT relocation. We could explain 
the reasoning why we don't think such relocation is a good idea. Apart 
from the significant amount of extra work and loss of the commissioning 
time, there are detector safety and extra risk analysis issues (SVT and 
MVT OSP, ODH, flammable gas, DA signatures are only valid for EEL124).

Ignoring all the offending language inappropriate by JLab standards of 
conduct, I would only clarify that I was indeed helping the janitor 
reportedly hired by the DSG to clean the EEL124 during the SVT 
assembling activities in the period when it was critical for the 
project. I insisted on patching the broken floor for the same reason. 
Did vacuum cleaning and floor mopping multiple times, signed the 
cleaning schedule paper posted in the gowning room. When SVT was 
integrated and purged with nitrogen, it became adequate for the project 
activities in the clean room to have less frequent cleanings (done 
solely by the mentioned janitor). Most of the SVT commissioning activity 
nowadays is done remotely, no mess created :-). I am not aware of any 
DSG requests for other users of the clean room (DC, MM, RICH) to 
participate in the cleaning. Claiming that the cleaning should be done 
only by me and the hired janitor is strange.
