Bill > S1170

This bill establishes comprehensive regulations for ore processing by cyanidation (a method of extracting precious metals using cyanide solution) in Idaho. The legislation repeals an existing section of law and replaces it with a detailed framework for permitting, constructing, operating, and closing cyanidation facilities. Key provisions include requiring permits from the Idaho Department of Environmental Quality for new or materially modified cyanidation facilities, mandating rigorous technical and procedural review processes, establishing strict environmental protection standards to prevent water pollution, and implementing extensive public notice and comment requirements. The bill defines numerous technical terms, outlines specific requirements for permit applications, water quality monitoring, and facility design, and provides for public involvement through notices, meetings, and comment periods. The legislation aims to ensure that cyanidation facilities are designed, constructed, and operated in a manner that prevents the discharge of harmful pollutants into the state's water resources. The bill includes provisions for permit review timelines, potential extensions, and emergency rulemaking, with most provisions applying to permit applications submitted on or before January 1, 2025.
