IMPORTANT:Ensure that each individual who will be involved in shipping/transportation of hazardous material is current with required training(awareness,function-
<br /> specific,safety,security)in accordance with applicable regulatory authority(DOT,FAA,IATA,TDG),and ensure adherence to applicable regulations.

<br /> E.1. AIR MONITORING ® Applicable Not Applicable, Not Anticipated
<br /> Site-Specific Notes,Clarifications: Site specific COCl are not believed to be an exposure risk to workers installing the SVPs;however,VOCs will be monitored in the
<br /> breathing zone using a PID.Air monitoring of worker breathing zone will be performed by Geosyntec personnel while the boring is being advanced. A photoionization
<br /> detector with 11.7 eV lamp,properly calibrated in accordance with manufacturer's instructions,will be used for monitoring of volatile organic compounds(VOCs)in the
<br /> worker breathing zone during these activities. Worker breathing zone readings will be recorded on no less than a 15-minute frequency. Background readings will also be
<br /> recorded and any sustained(longer than 5 seconds)detection above background levels will result in work stoppage so that engineering controls can be instituted;this will
<br /> consist of electrically powered fans for the displacement of VOCs from the breathing zone.If sustained(longer than 5 seconds)detections above background level are still
<br /> detected after engineering controls are in place then work shall stop and either additional engineering controls shall be put in use before resuming work activities or the
<br /> boring will be terminated.
<br /> The primary VOC compound of concern is Propylene dichloride(1,2-dichloropropane)which has a ACGIH®2018 8 hour limit of 10 ppm.
