Within the boundaries of the Idaho National Laboratory, an ongoing archaeological investigation of a late 19 th century stage station was expanded with the use of Electro-Magnetic and Magnetic geophysical surveying. The station known as the Powell Stage Station was a primary transportation hub on the Snake River Plain, bridging the gap between railroad supply depots in Blackfoot, Idaho and booming mining camps throughout Central Idaho. Initial investigations have shown a strong magnetic signature from a buried road and previously unknown features that were not detected by visual surface surveys. Data gained from this project aids in federally directed cultural resource and land management use requirements and has contributed additional information for archeological interpretation and cultural resource preservation.

The U. S. Department of Energy (DOE) has a need to test nuclear fuels under conditions that subject them to short bursts of intense, high-power radiation called 'transient testing' in order to gain important information necessary for licensing new nuclear fuels for use in U.S. nuclear power plants, for developing information to help improve current nuclear power plant performance and sustainability, for improving the affordability of new generation reactors, for developing recyclable nuclear fuels, and for developing fuels that inhibit any repurposing into nuclear weapons. To meet this mission need, DOE is considering alternatives for re-use and modification of existing nuclear reactor facilities to support a renewed transient testing program. One alternative under consideration involves restarting the Transient Reactor Test reactor (TREAT) located at the Materials and Fuels Complex (MFC) on the Idaho National Laboratory (INL) Site in southeastern Idaho.This report summarizes cultural resource investigations conducted by the INL Cultural Resource Management (CRM) Office in 2013 to support environmental review of activities associated with the Resumption of Transient Testing (RTT) project and associated restart of the TREAT reactor at the INL. These investigations were completed in order to identify and assess the significance of cultural resources within areas of potential effect associated with the proposed action and determine if the RTT project would affect significant cultural resources or historic properties that are eligible for nomination to the National Register

The U. S. Department of Energy, Idaho Operations Office is considering options for construction of a facility for disposal of Idaho National Laboratory (INL) generated remote-handled low-level waste.
