Environmental Impact Statements and Regulations; Availability of EPA Comments

EPA expressed environmental objections because waste rock from several pits could generate leachate with high concentrations of metals and metalloids, and degrade water quality if the leachate should reach groundwater or surface waters, or if pit lakes would form. Also, EPA expressed concerns about potential impacts to air quality and the lack of suitable soil for reclamation. EPA recommends the additional information on waste rock geochemical characterization, potential impacts to water and air resources, mitigation and monitoring, and closure and reclamation. Rating EO2.
