Cotter Uranium Mill Superfund Site, Colorado
We’re finding some interesting things with the FEMA flood data. Yesterday it was coal-combustion waste storage in high-risk flood zones; today it’s uranium mill process wastes:
The Cotter Corporation, a subsidiary of General Atomics, began operating a uranium mill on the outskirts of Canon City, Colorado, in 1958. Liquid wastes containing radionuclides and heavy metals were discharged from 1958 to 1978 into eleven unlined tailings ponds. The ponds were replaced in 1982 with the construction of two lined impoundments. Prior to 1982, a number of Lincoln Park wells showed elevated levels of contamination. The site was placed on the National Priorities List (NPL) of Superfund sites on September 21, 1984.
In 2001, Cotter Corp. applied for a license amendment to reopen the mill. (Click here for more information).
We overlaid flood data from FEMA showing areas at high risk of flooding that cross the Cotter facility and lead directly into residential neighborhoods just one mile from the site. Check out our small gallery of images.
Yikes. I wonder what we’ll find tomorrow.
