EPA begins to clean up black globs of asphalt from Yellowstone River train derailment

Environmental agency officials said workers are cooling the gooey material with river water and putting it into garbage bags for recycling

Globs of asphalt binder that spilled into Montana's Yellowstone River during a bridge collapse and train derailment could be seen on islands and riverbanks downstream from Yellowstone National Park a week after the spill occurred, witnesses report.

Officials with the Environmental Protection Agency said cleanup efforts began on Sunday, with workers cooling the gooey material with river water, rolling it up and putting the globs into garbage bags. It will probably be recycled, said Paul Peronard with the EPA.
