Community Air Monitoring Plan Summary

Community air monitoring, initiated on Tuesday, December 1, 2015, continues as intrusive (ground disturbance) activities are conducted.

There were no fifteen-minute Action Level exceedances of Total Volatile Organic Compounds (TVOCs) or odors associated with Site activities during this reporting period.

A fifteen-minute Action Level exceedance for particulate matter (PM-10) [average dust concentration] occurred on January 12, 2016 at air monitoring station 3 (AMS-3) from 9:22 a.m. to 9:33 a.m. This exceedance was due to dust from breaking clean asphalt and concrete in preparation for excavating a test pit over the Holder No. 2 tank. Odor/dust suppressant foam was applied to the area, and dust levels returned to below the Action Limit.

Community Air Monitoring Plan Summary

Community air monitoring, initiated on Tuesday, December 1, 2015, continues as intrusive (ground disturbance) activities are conducted.

There were no fifteen-minute Action Limit exceedances for Total Volatile Organic Compounds (TVOCs) or odors during this reporting period.

There were three instances of the fifteen-minute average concentration of Particulate Matter (PM-10) [dust] exceeding the applicable Action Limit: On August 8 at AMS-2 due to dust created during breaking clean asphalt and concrete; on August 9 at AMS-2 due to dust created during compaction of clean backfill; and on August 11 at AMS-3 due to dust created during reuse material crushing activities. When SES applied additional water, dust levels returned to below the Response Limit. SES was directed to wet all areas down prior to initiating work that creates dust and throughout the duration of those activities.

Community Air Monitoring Plan Summary

Community air monitoring, initiated on Tuesday, December 1, 2015, continues as intrusive (ground disturbance) activities are conducted.

There were no fifteen-minute Action Limit exceedances for Particulate Matter (PM-10) [dust], Total Volatile Organic Compounds (TVOC), or odors during this reporting period.

There was one instance of the Particulate Matter (PM-10) [dust] levels exceeding the Action Limit at AMS-2 on November 9 at the eastern area of the Site. No work was being performed in this area at the time, and dust levels quickly returned to below the Response Limit.

Community Air Monitoring Plan Summary

Community air monitoring, initiated on Tuesday, December 1, 2015, continues as intrusive (ground disturbance) activities are conducted.

There were no fifteen-minute Action Limit exceedances for Particulate Matter (PM-10) [dust], Total Volatile Organic Compounds (TVOC), or odors during this reporting period.

There were three instances on Friday evening and Saturday morning, November 18 and 19, where benzene levels exceeded the Action Limit during nonworking hours. Employees were called back to the Site to repair breaches and tears in the TCB fabric and to apply additional foam to the material stockpiled in the TCB. Once these items were addressed, benzene and TVOC levels returned to below the Response Limit.

Community Air Monitoring Plan Summary

Community air monitoring, initiated on Tuesday, December 1, 2015, continues as intrusive (ground disturbance) activities are conducted.

There were no fifteen-minute Action Limit exceedances for Particulate Matter (PM-10) [dust], Total Volatile Organic Compounds (TVOC), or odors during this reporting period.

The Action Limit for Particulate Matter (PM-10) [dust], was exceeded at AMS-3 on December 15, 2016 at multiple times throughout the day. High winds were observed directing visible plumes of dust from the clean backfill areas towards the station. Calcium chloride was applied to the Site surface to suppress dust levels.

The Action Limit of 1.0 ppm for benzene was exceeded at AMS-3 on Saturday, December 18, 2016 from 6:49 to 6:51 am. During this time, no Site activity was taking place, and the winds were calm.
