From the Cañon City Daily Record (Rachel Alexander):
A contractor is on site laying the first layer of final cover on the secondary impoundment, which was dried out over the last year. “They’re making a lot of good progress,” [Cotter Mill Manager John Hamrick] said…
He said once the impoundment dried, the top did not turn out as expected. He described the top level as “Jell-O or pudding.” The company is mixing it with dry soil prior to topping the impoundment with clean soil. The same contractor also will be excavating soil from under historic ore pads that may have pathways for contaminates to groundwater.
Also this year, Cotter is working on taking down the CCD tanks. The company had hoped to be further along in the CCD tank removal process, but discovered asbestos in the metal bands that delayed the process.
