The OSAT-2 report provides a Net Environmental Benefit Analysis comparing environmental and human health risks of this remnant oil compared to the environmental risks of pursuing further, more aggressive, cleanup efforts.
The purpose of this report is to provide the Federal On-Scene Coordinator (FOSC) for the Deepwater Horizon MC252 Spill of National Significance with a risk-based Net Environmental Benefits Analysis (NEBA) associated with removing remnant oil from the near shore, surf zone, and shoreline sandy beach areas.
This report was produced by primarily relying on data collected along the shoreline prior to the OSAT-2 effort. These data, however, were supplemented with laboratory and modeling information and certain supplemental data acquired during the course of the study. While no single source of information used by OSAT is conclusive, the multiple lines of evidence obtained informed the conclusions.
