Community Air Monitoring Plan Summary

Continuous community air monitoring is on-going.  For the period 10/28/21 through 11/03/21 there were no levels above the 15-minute Action Limit for Total Volatile Organic Compounds (TVOC) associated with Site activities.  On 11/01/21 there were two 15-minute periods when Particulate Matter (PM-10) concentrations were above the Action Limit.  The elevated PM-10 concentrations were caused by the exhaust from an operating truck blowing directly into an air monitoring station.  The truck was moved and no additional levels greater than the 15-minute Action Level for PM-10 occurred during the reporting period.
