Ablation Process - Black Range Minerals

On December 1, 2016, The Department issued a determination that the proposed ablation operations at the Sunday Mine by Black Range Minerals must be regulated by the Department through a milling license pursuant to Part 18 of the Regulations.


In July 2015, Black Range Minerals submitted information to the department about its ablation technology and asked the department to make a determination on how this technology would be regulated under the Colorado Rules and Regulations Pertaining to Radiation Control.
We requested additional information from Black Range in August 2015 and received a response from Black Range in April 2016.
We conducted a 75-day stakeholder process between May 9 and July 22, 2016 including four public meetings across Colorado, and obtained several hundred written and oral public comments.
