Large scale dredging begins in Calhoun Co.
CALHOUN COUNTY, Mich. (NEWSCHANNEL 3) - Large scale dredging has begun in a second area on the Kalamazoo River.
Enbridge Energy's work is centered around a dredge pad site in Emmett Township in Calhoun County, where sediment from the river is being collected and treated.
It's a slow and deliberate process, removing mud that could be contaminated from the bottom of the river.
"The dredge will actually agitate the sediment, then it will suck the sediment through the pipe," says Christopher Haux with Enbridge.
Haux, Enbridges Senior Project Manager gave Newschannel Three an up close look at how Enbridge's EPA ordered dredging is progressing. Right now its dredge boat is near Emmett Township working in section five of 38 sections it will clear.
The sediment is pumped upriver to the 10 acre dredge pad site set up near Mill Pond.
Its kept in large bags as it drains into a retention pond. Enbridge says it's done everything possible to keep any of that water out of the ground.
"Theres this polymer on the bottom, welded together, completely impenetrable for the whole site. We then put six inches of sand on top of that, six inches of stone gravel on that," says Haux.
Water in the retention pond is treated and sent back to the river.
There has been controversy around these dredge pad sites, with questions about noise and smell, which Enbridge says it has worked to address.
"You can hear the noise, this is active right now and it's not very noisy, there is no odor at this time and we're working with landowners," says Haux.
Along with Emmett Township Enbridge is also dredging near Marshall, it will next dredge around Morrow Dam in Kalamazoo County.
