The Rover pipeline will run through three counties in southeast Michigan once it's built.
But for now, the company building the natural gas pipeline, is busy cleaning up mud.
According to Ohio EPA spokesperson James Lee, Energy Transfer reported two bentonite spills in mid-April.
"[Bentonite is] a natural clay mud used as a lubricant for drilling," Lee said. "It's a common application; [bentonite] doesn't contain any additives or chemicals."
