Under the proposed action, the U.S. Geological Survey drills up to eight boreholes, each with ≤10 inch diameter and extending to depths between 800 and 1,600 feet, at four locations on the Idaho National Laboratory Site. After seismic measurement collection, U.S. Geological Survey may take ownership of the boreholes for future monitoring activities.
