Harbour dredging small Canadian harboursNews // February 28, 2011
The Times & transcript reports that the Department of Fisheries and Oceans is applying for permits that would allow it to remove sand from harbours and dump it further out to sea.It's a pre-emptive move, in case dredging is needed later this year, says Jacques Robichaud of DFO.
"It's based on estimates from previous years, where typically we usually dredge every couple of years," Robichaud says.
The ebb and flow of the tides can render harbours too shallow for boats, so the DFO uses dredgers to remove the sand and dump it outside harbours.
Often, the dredging takes place in the spring to accommodate fisheries but the work can go on spring, summer and fall, usually lasting only a few days. "It's a challenge," Robichaud says. "There are a lot of harbours."
To carry out the work, the federal Department of Public Works needs to acquire a "disposal at sea" permit from Environment Canada.
It must also pass an environmental review. Requests for information on the environmental assessment and permitting process can be addressed to Jayne Roma, Disposal At Sea Program, Environmental Protection Branch, Environment Canada, 16th Floor, Queen Square, 45 Alderney Dr, Dartmouth, NS, B2Y 2N6.
In Kent County, the DFO expects to dredge about 92,000 cubic metres from harbours in Pointe Sapin, Saint-Edouard, Cap Lumiere, Chockpish, Loggiecroft, Blacklands Gully, Barre de Cocagne and Caissie Cape.
In Westmorland County, they expect to remove about 39,000 cubic metres of sediment from harbours at Botsford, Cap Pele, Aboiteaux, Little Cape and Robichaud.
