The United States Environmental Protection Agency finalized a Record of Decision Amendment significantly lowering the residential soil-lead cleanup threshold in Butte, Montana. The regulatory action reduces the allowable limit from 1,200 parts per million down to 456 parts per million across the Butte Priority Soils Operable Unit. Announced by EPA Regional Administrator Cyrus Western, the decision expands the Residential Metals Abatement Program footprint by approximately 3,627 acres, qualifying more than 7,000 additional properties for environmental assessment and potential remediation. Montana Department of Environmental Quality Director Sonja Nowakowski expressed support for the collaborative multi-agency review process. Officials stated that properties exceeding the updated threshold will undergo systematic soil excavation and replacement with clean fill over a projected 15-year timeline. The federal decision incorporates standards from the October 2025 Residential Lead Directive, targeting a blood-lead level of five micrograms per deciliter to minimize toxic exposure risks for vulnerable local children and families.
