In early December, the U.S. Environmental Protection Agency (EPA) took actions to control blowing dust from the grayish-colored waste dross on the former smelter property. EPA applied a product called Posi-Shell over the waste dross material. This forms a crust over the dross to prevent its entrainment by wind.
This past fall, EPA placed nine warning signs in areas on or near the former smelter property and former Iron King Mine property. These signs warn of chemical and physical hazards in these areas. In addition, EPA placed fencing at the former smelter property to limit public access. EPA continues to work with the owner of the former Iron King Mine property to upgrade and add fencing.
