watering prior to excavation will also be needed and treatment of the ground water may be required prior to discharge. The CAP should also be desigactivity and use restrictions such as avoiding sub-grade basements reducinpump, treat and discharge ground water and restricting residential occuground floor. Notice to Land Records will likely be required.

If future Site development includes removing the floor of the Rutland Herald

Building or demolishing any portion of the Rutland Herald Building, shallow soil samples from beneath the floor for PCB analysis is recommended. Based on

versations with the VTDEC, LBG proposes collecting ground-water MW-1, MW-2, and the sump within the sub-grade basement; and collectingthe sludge for PCB analysis.
