Notwithstanding the provisions of section 31-808, Idaho Code, county hospital boards may dispose of personal property previously purchased, paid for, or otherwise acquired by the board, so long as any such property to be disposed of has a resale or salvage value not in excess of five thousand dollars ($5,000) and is not a fixture under section 55-101, Idaho Code; provided, that the board shall notify the public of its intent to dispose of any such property prior to sale by publication once in a newspaper of general circulation within the county. Where any such property, regardless of resale or salvage value may, in the board’s judgment, pose a threat to public health or safety if disposed of at public auction, the board is authorized to dispose of it without regard to the provisions of section 31-808, Idaho Code.
