The Associated Press is reporting, Nevada is trying to back out of the agreement with the EPA, to allow “Superfund” status at the former Anaconda Copper mine near Yerington. Great Basin Resource Watch accuses state of a clandestine effort to make the state the lead authority on the toxic mess, furthering delaying cleanup. The state sent the EPA a formal request on July 31 to keep the site off the priority list. EPA spokeswoman Margo Perez-Sullivan confirmed the agency is evaluating the request.
