"Contamination of waters, beaches, shorelines, and wildlife after oil spills is the subject of increasing public concern. In many areas, members of the local communities have demonstrated their concern by arriving at the sites of oil spills and volunteering to participate in efforts to clean up affected areas. The volunteers often arrive in large numbers and are usually untrained in oil spill response and clean up. The National Oil and Hazardous Substances Pollution Contingency Plan (NCP) specifies that a designated federal On-Scene Coordinator (OSC) coordinate and direct federal activities at the site of certain response and removal actions, including the way in which volunteers will be used."
