"And Koch (Brothers) Carbon isn’t talking."

And what aren't Dave and Charles talking about?

"Final destination for refinery waste a secret"

"A four-story mound of black, gritty refinery waste that recently was ordered off the banks of the Detroit River likely was moved to Ohio. Where? Those who know aren’t saying."

"Since the spring of 2012, the pile at Detroit Bulk Storage had grown and grown. After complaints from neighbors and environmental groups, the situation finally was resolved last week when Detroit Mayor Dave Bing ordered Wichita, Kan.-based Koch Carbon to move its mountain."

"Brad Wurfel, spokesman for the Michigan Department of Environmental Quality, said he was told that the pile was shipped to Ohio. But he said he didn’t know where. And Koch Carbon isn’t talking."

"Wurfel said pet coke is similar to coal but has a higher sulfur content. A power plant that burns it without a scrubber or other filter would release pollutants that contribute to smog, soot and acid rain."

Me thinks AEP may know where this mountain of Koch's pet coke went.
