This bill repeals the current Section 39-118A of the Idaho Code concerning ore processing by cyanidation and introduces a new Section 39-118A that establishes comprehensive regulations for cyanidation facilities. The new section defines essential terms such as "application," "cyanidation facility," and "cyanidation pollutants," and sets forth the requirements for obtaining permits for new or materially modified facilities. It emphasizes the need for these facilities to be designed and operated to prevent the discharge of cyanidation pollutants that could harm water quality, and it requires a permanent closure plan and financial assurance prior to permit issuance.

Additionally, the bill nullifies certain administrative rules in IDAPA 58.01.13, effectively removing previous regulatory frameworks for cyanidation processes. It introduces stringent controls for permit issuance, including conditions to mitigate cyanidation pollutants, public involvement procedures, and timelines for permit validity and construction commencement. The bill also mandates the development of a mailing list for interested parties and public meetings within specified timeframes, while allowing retroactive application of its provisions to pending permit applications. The department is tasked with reviewing and updating existing rules to align with the new requirements by July 1, 2025.
