ID HCR008

The Idaho Legislature asserts that the populated areas of the Bunker Hill Mining and Metallurgical Complex Superfund Site (Residential Soils Operable Unit 1) should be delisted from the overall Superfund site and urges the Governor to petition the EPA for this delisting.

All residential remediation activities in the affected communities (Kellogg, Wardner, Smelterville, Page, Pinehurst, Elizabeth Park, Ross Ranch, and Montgomery Gulch) were certified as completed by 2008 with soil lead concentrations meeting or exceeding cleanup standards.

Average blood lead levels in children from the populated areas have remained below the CDC health standard of 5 micrograms per deciliter since between 1980-1982, and measured 3 micrograms per deciliter in 2017.

Over $665 million from two settlements has funded cleanup actions, with remediation including removal of contaminated topsoil, visual markers for lead deposits exceeding 1,000 ppm, and replacement with clean soil and vegetation.

The 1995 EPA policy allows partial delisting of Superfund sites with State concurrence when no further response is appropriate for specific geographic portions, and such petitions may be submitted by States, local governments, and other entities.
