This bill addresses the cleanup of contaminated land historically conveyed to Alaska Native groups and tribes under the 1971 Alaska Native Claims Settlement Act. The legislation makes Alaska Native corporations and tribes newly eligible for federal brownfield revitalization grants and increases the grant cap from $500,000 to $1,000,000 per site. It authorizes $35 million annually from 2025 through 2030 for a new grant program specifically for remediating contaminated Alaska Native lands, while directing the Interior Department to develop a cleanup plan and report to Congress annually for ten years on contamination sites. Additionally, the bill permits tribes to directly manage Army Corps of Engineers construction projects through a pilot program funded at $15 million per year from 2025 to 2029, allows contaminated land remediation to count toward wetland mitigation requirements, and requires federal agencies to submit a report on remediation efforts and additional cleanup authorities needed. Congress finds that the federal government failed to properly identify and remediate over 44 million contaminated acres transferred to Alaska Natives over 50 years ago, and recognizes at least 920 contaminated sites remain unresolved.
