Description:In the event that none of the approved techniques adequately address the subsurface oil treatment problem, the Federal On-Scene Coordinator requested that Exxon determine the feasibility of use of an excavation/rock washing process. Exxon agreed to manage the design and demonstration of a rock washer for removal of subsurface oil as long as an assessment of the net environmental benefit was conducted simultaneously with the engineering development. A committee was formed with representatives from the National Oceanic and Atmospheric Administration (NOAA), State of Alaska, and Exxon, with NOAA designated as the chair, to conduct a Net Environmental Benefit Analysis (NEBA), working in close conjunction with the Engineering Process committee. The NEBA committee was charged with the task to determine if there were net environmental benefits from the excavation and washing of oiled sediments, and return of treated sediments to the excavated site over natural cleansing and the use of approved 1990 treatments.
