CX-270337: Box Canyon Subsurface Applied Research Site Cleanup

Idaho National Laboratory's (INL's) Subsurface Applied Research Site is located on the north rim of Box Canyon on the Big Lost River 3.35 miles southeast of Butte City, Idaho on land managed by the Bureau of Land Management (BLM). Access to the site is from a gravel road off of Highway 20/26 near mile marker 251 and a two-track road that leads to the canyon rim (see Figures 1 and 2). Initial research at this location was part of the Buried Waste Integrated Demonstration Program and was associated with a monolithic confinement technology demonstration. The project was described in Environmental Checklist OFF-93-040, and an Environmental Assessment and FONSI were issued by the BLM in 1994 (EA number ID-030-4-14, January 1994).
