Supply Fan 1 at EX had faulty bearing(s) which was causing excessive noise. Macdonald Miller was on site this week to carry out the repairs. The work began Monday (5/6) and was completed Tuesday (5/7). The duration of the work was approximately the same on both days (8am-4:30pm) with brief lunch breaks around noon. All of the work was contained to the mechanical space of the end station.
