The Montana Department of Environmental Quality said in a news release the crews would be focusing on the river 21 to 35 miles below the derailment. That would be roughly from Columbus downstream to Park City.
The cleanup is being conducted through cooperation by a collection of agencies that includes DEQ, the Environmental Protection Agency, Montana Rail Link and Stillwater County Disaster and Emergency Services.
The crews are taking advantage of lower river levels to recover the asphalt. However, lower water means the work won’t be done by boat.
Asphalt that can’t be removed will be broken into smaller pieces and covered with sediment “to aid in the natural breakdown process,” DEQ wrote.
