Tudor Wharf Draft Environmental Impact Report EOEA # 6744 



The dredging will be accomplished by 

 using a barge mounted crane and 

 clamshell. If the material is to be 

 disposed of at sea, the spoils will be 

 placed directly into a dump scow. If the 

 material is to be disposed of on land, 

 the material will be placed directly into 

 trucks on site. 



6.5 Turbidity caused by Charles River flow 



During dredging operations, which will 

 take only two to three days to 

 accomplish, care will be taken to prevent 

 silt from fouling the harbor. Due to the 

 proximity of the Charles River Dam 

 discharge, heavy flows from the dam could 

 cause sediments from the dredging 

 operations to be moved off site. The 

 contractor will not perform dredging 

 operations when the dam pumps are 

 running, and will also place a 

 containment boom around the area to be 

 dredged during all dredging operations. 

 The boom will limit the off site 

 migration of sediment during the dredging 

 operations. ,
