In October 2007, at the request of the U.S. House Committee on Oversight and Government Reform the United States Environmental Protection Agency (EPA), along with the Bureau of Indian Affairs (BIA), the Nuclear Regulatory Commission (NRC), the Department of Energy (DOE), and the Indian Health Service (IHS) developed a coordinated Five-Year Plan to address uranium contamination in consultation with Navajo Nation. The Five-Year Plan was the first coordinated approach by the agencies, and outlined a strategy for gaining a better understanding of the scope of the problem and for addressing the greatest risks first. The following objectives were developed as part of the Five-Year Plan:

  • Assessment and cleanup of contaminated structures
  • Assessment of contaminated water sources, and provision of alternative water supplies
  • Assessment of abandoned uranium mines, with detailed assessments of those most likely to pose environmental or health problems
  • Cleanup of the Northeast Church Rock mine site and additional high-priority abandoned mine sites
  • Cleanup of the Tuba City Highway 160 site
  • Cleanup of the Tuba City Dump
  • Remediation of groundwater contamination at three former mill sites
  • Case control studies of health risks faced by individuals residing near mill sites or abandoned mine sites
