The Bay City Times reports the tug boat sank early Monday spilling 800 gallons of diesel fuel.
It's reported that Grand Rapids-based Young's Environmental Cleanup Inc. and Mt. Clements-based HM Environmental Services are working to contain and clean up the spill.
The cause of the sinking won't be known until the tug is pulled from the river. Paul Luedtke of Luedtke Engineering, the company that owns the boat, said:
"We won't know until then and anything before then would just be speculation."
A crane will pull the tug from the water once the diesel spill is cleaned up.
