The new EX purge air compressor and drying skid were turned on this morning at ~8am and dewpoint and particulate measurements were taken at ~11:30am.  See attached pics of the dewpoint monitor at the exhaust of the drying tower, dewpoint at the coupling fitting at the EX spool just upstream of BSC9, and particulate counts at the same spool coupling.  FTIR sample was taken of the coupling fitting and will be stored onsite.
