Governor Bill Ritter signed a bill in Canon City Tuesday afternoon to tighten regulations on radioactive waste in Colorado. It requires uranium mills to clean up radioactive waste before accepting more radioactive material.
Uranium mills are now allowed to postpone cleanup until they finish production and decommission their facilities. Plans to re-open the Cotter Mill in Canon City, which has been a Superfund site since 1984, and open a mill in Montrose County led environmental groups to push for the change in the Colorado law.
Cotter has said the future of the Canon City operation is now uncertain. Cotter Corporation announced last year a desire to refurbish the Canon City mill and begin processing ore from New Mexico as soon as 2014.
