Week of March 21-27, 2020

• Weekly Summary
  Note: There was an exceedance of the daily dust action level on Monday, March 22nd.  The OU6 Actual Daily Dust Average was reported at 0.039 mg/m3.   According to the data, the exceedance was caused by the hourly emptying of the Frac Tank water into a Vac Truck for transport to OU4.  The water removal process is done with a large vacuum and the process emits water moisture to the surrounding area impacting the nearby air monitor (Meter 2).  Chemical sampling data shows that chemicals were not detected in dust at levels that would adversely impact workers or the community.
