9. In drawings C-101 thru C-110, the phragmities excavation areas are 1) hatched to indicate MA Lined landfill, 2) hatched to indicate out of state non-RCRA, or 3) not classified by a hatching. Is the disposal for the all phragmities excavated materials MA Lined Landfill? If not, please provide guidance for all excavation areas without a disposal hatching.

RESPONSE: The disposal of phragmites excavated from within flood control channel shall be disposed in accordance with the adjacent excavated sediment hatching. Disposal of phragmites beyond the flood control channel shall be MA lined landfill.

11. Specification 01 74 19 Part 1.1 states that contractors “Divert a minimum of 60 percent by weight of total project solid waste from the landfill.” Does this statement apply to excavated sediments, which are identified for disposal at landfills per the contract drawings?

RESPONSE: The contractor will be responsible to ensure that blueback herring can reach areas upstream and downstream of the project either by allowing free passage in the river or by truck transport.

RESPONSE: This requirement only pertains to temporary sheet piles. There is no permanent sheet pile requirement.
