Committee advances bills to strengthen mine-sale disclosures and allow third‑party cleanup
Summary
The House Natural Resources, Energy and Water Committee advanced three measures from Rep. Selena Bliss aimed at improving disclosure when contaminated properties are sold and enabling voluntary remediation of abandoned hard‑rock mines after testimony about the Senator Mine in Yavapai County.
Representative Selena Bliss (sponsor) told the committee the bills grew from a local contamination fight in Yavapai County and the “Senator Mine” incident where an owner stopped responding to regulators and the site was later listed for sale without disclosure of ongoing regulatory actions.
The committee returned House Bill 21‑27, as amended, with a due‑pass recommendation after the sponsor and several local officials described community, county and state agency response to hazardous releases at legacy mine sites. The motion passed 10‑0.
Why it matters: Bliss said the law change would “require the owner of a property that has previously been labeled a site of released hazardous materials to notify the prospective buyers” and would, in certain cases, also require notice to ADEQ and the state mine inspector; the committee-approved amendment narrowed and clarified when agencies are notified.
Sponsor and local testimony: “We have ongoing litigation,” Representative Selena Bliss said, summarizing a sequence of regulatory visits, nonresponsive owners and community concern that led to the bills. Yavapai County Supervisor Mary Mallory said state agencies have been “very active in helping to clean up” but that local constraints remain. Resident Joe Trudeau described seeing “mustard yellow” tailings flushed into the Hassayampa River during high run‑off and said local listings did not disclose enforcement actions.
Pros and cons at the hearing: The Arizona Mining Association and industry witnesses supported the bill with suggested clarifications to avoid duplicating existing disclosure requirements for properties that already undergo Phase I environmental site assessments, while environmental and civic groups urged stronger public notification and protections for communities that have borne pollution burdens.
Prospective remediator proposal: The committee also returned House Bill 21‑28, which would create a “prospective remediator” status in ADEQ’s Water Quality Assurance Revolving Fund registry and extend protections available to prospective purchasers to qualified third‑party remediators. Bliss said ADEQ identified a gap preventing NGOs and non‑purchasing operators from participating in voluntary cleanup programs.
ADEQ reaction and next steps: Matt Rippin Chop of the Arizona Department of Environmental Quality said the agency is neutral on the bill but asked the sponsor to consider additional conditions in the prospective‑remediator agreements to ensure technical and financial capability. The committee passed HB 21‑28 8‑2, with members asking for follow‑up language from the sponsor and ADEQ.
Federal pilot urged: House Concurrent Memorial 20‑07, also advanced by the committee, urges the Arizona State Mine Inspector and ADEQ to apply for the federal Good Samaritan remediation pilot program created by Congress in 2024. Bliss told the committee Arizona should pursue the pilot to enable voluntary cleanups; the motion passed 10‑0.
