With high pressure in the area and a few fires in the area (Red Mountain nearby, and a huge one near Cle Elum, WA), wanted to check for particle levels on the site. 

In the attached 48-hr trend, it shows that we had elevated dust levels observed mainly in the End Stations, with EY showing a huge explosion (almost 300K particles!).  The high dust levels mainly occurred from 8pm-2am.
