There has been an instrument air alarm periodically for MX since the start of my shift.  It seems to have come back after the power outage to a lower level than previous (~60 instead of ~80 psi).  I talked to Gerardo about it, and he didn't seem to worried.  I have emailed Bubba to look at it tomorrow.  OPS takeaway: it is OK to ignore this alarms (which is a MINOR alarm) for now, unless it becomes MAJOR.
