The Glenrock and Coal Creek Mining Group includes historic mine features within several watersheds northeast of Glenrock, WY where Tronox once operated. EPA's Emergency Response Branch is conducting a Removal evaluation in the area. EPA is currently generating maps and expects to engage and share information with stakeholders in Spring 2020. This will be followed by field reconnaissance in Summer 2020.
