The Corps is proposing to use the fly ash as part of a lime slurry mixture for some kind of grouting to stabilize the levees according to the article. Environmentalists are concerned about the potential impacts of residual toxins in the fly ash. However, they are drawing comparisons to the TVA coal ash dam failure. From my perspective, this is an unfair comparison since this fly ash would be mixed with lime and in theory any toxins would be bound up in the grout matrix. But it never hurts to be cautious regarding potential contaminants that close to such an important waterway. [Source: bnd.com via ASCE SmartBrief]

Corps releases Center Hill Dam Consensus Report
WASHINGTON–The U.S. Army Corps of Engineers (USACE) today released the Center Hill Dam Consensus Report, an external independent peer review that validates the USACE high-risk classification of the dam and the interim risk reduction measures currently in effect.
This is the second peer review report on a high-risk USACE dam, and it provides important input regarding current USACE efforts to investigate, monitor and modify Center Hill Dam. [Editor] (Photo by drainhook) [/Editor]

A forthcoming draft study by the Army Corps of Engineers will hopefully shed light on an ongoing problem of stream bed degradation along the Missouri River. Portions of the river in Kansas City have dropped […]

I agree that the toxins will be chemically bound into the grout. There may be some leachate but nothing that compares to TVA coal ash dam failure, a dam that was built to hold back a toxic sludge. It was the sludge that caused the contamination not the dam. It would be like comparing a drip of oil from my truck to the Horizon debacle in the Gulf of Mexico. I guess the ACOE could just do nothing, will the environmentalists be there when the levees fail?
