Lincoln Park/Cotter Mill superfund site update: The dismantling of contaminated strutures has cost Cotter $3.5 million so far


From The Denver Post (Bruce Finley):

Cotter Corp. crews this week jack-hammered concrete foundations and ripped apart contaminated remaining buildings at their uranium mill, pushing to consolidate all waste in a massive impoundment pond by year’s end.

Next year, workers will dig out toxic soil 4 feet deep and bury that too, said John Hamrick, Cotter’s vice president for mill operations, outlining a dismantling project that he said has cost $3.5 million so far.

The project eventually will include construction of a new evaporative waste pond to store water pumped from a potentially contaminated creek that flows near Cotter’s property, Hamrick said…

Ten new groundwater-testing wells are to be built in a nearby urban neighborhood to monitor toxic plumes, along with additional wells west of the mill, where the latest underground plume of cancer-causing trichloroethylene was discovered last year…

State health department regulators have let Cotter deliberate on whether to reopen or embark on total cleanup and restoration of the site. But now Cotter’s operating license is about to expire. Cotter must decide by January whether to renew or to move toward reclamation and closure…

Federal authorities during the Cold War backed creation of the mill to process uranium for nuclear weapons. In 1984, the mill was deemed a Superfund environmental disaster. Toxic metal waste contaminated residential wells near Cañon City.
