Update for the Week Ending January 6, 2017
Site Remediation Continues
- Continued the application of water for dust control;
- Continued the application of foam and BioSolve for Total Volatile Organic Compounds (TVOC), Particulate Matter (PM-10) [dust], and odor control;
- Maintained erosion and sediment (E&S) controls (Installed waddles - wood chip and straw filled fabric tubes - around the Site perimeter to prevent silt and sediment from leaving the Site and covered all stockpiles);
- Continued pumping from the decontamination pads, excavated areas, sumps and dewatering wells to the water treatment plant (WTP);
- Continued operation of the WTP and discharge to the sewer;
- Continued deep excavation within the support of excavation (SOE) wall in the temporary containment building (TCB); and
- Continued lining and loading trucks and shipping impacted soil to Bayshore Soil Management for treatment and disposal:
- 201 trucks; 5,584.56 tons shipped this week; and
- 53,806.93 tons shipped to date.
- Initiate backfilling the deep excavation with crushed and stockpiled reuse material; and

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 15-minute Action Limit exceedances for Total Volatile Organic Compounds (TVOC) or odors.
The Action Limit of 150 ug/m3 for Particulate Matter (PM-10) [dust] was exceeded on January 5, 2017, at AMS-3 due to trucks releasing their air brakes near the CAM station. The Contractor spread additional calcium chloride on the clean backfill, and PM levels returned to below the Response Limit.
If you have any questions or comments about the work on the Site, please use the Williamsburg MGP Telephone Hotline at (718) 403-3053.
