The Federal On Scene Coordinator (Federal OSC), is a designation in the United States for an individual that:
The federal agency providing OSC might differ depending on the incident.
Federal OSCs are the federal officials predesignated by United States Environmental Protection Agency and the United States Coast Guard to coordinate response resources. The OSC, either directly or through his or her staff, monitors, provides technical assistance, and/or directs federal and potentially responsible party (PRP) resources. As the state and local responder’s gateway to the resources of the NRS, it is the OSC’s responsibility to provide access to resources and technical assistance that may not otherwise be available to a community. Under the NCP, if federal involvement is necessary because state and local resources have been exceeded, the OSC is obligated to coordinate the use of these resources to protect public health and the environment. (Note: An example of the OSC’s direction of PRP resources could be through participation in the Unified Command under the Incident Command System or issuance of an administrative order.)
During an oil or hazmat incident, EPA will usually provide OSCs in the inland zone, and the USCG will generally provide OSCs in the coastal zone. The OSC coordinates all federal containment, removal, and disposal efforts and resources during an incident under the NCP or the Federal Response Plan (FRP). The OSC is the point of contact for the coordination of federal efforts with those of the local response community. EPA has approximately 200 OSCs at 17 locations nationwide; USCG has 46 Marine Safety Offices (MSOs), spread among the nine USCG Districts, each of which is headed by a Captain of the Port (COTP), who acts as an OSC.
Agencies other than EPA or USCG might provide the OSC depending on the incident. While EPA and USCG have primary responsibility under federal laws and regulations, under CERCLA, DOD, DOE, and other federal agencies provide OSCs for incidents for which they have responsibility for releases of hazardous substances. If a federal agency other than EPA, USCG, DOD, or DOE – has responsibility for an incident, they only provide the OSC if the incident involves non-emergency removal actions. Each of the agencies in the NRS provides resources and technical expertise and has access to a wide range of federal assets, such as equipment and special expertise, through the RRT.
Under the NCP, OSCs have the responsibility to oversee development of the Area Contingency Plan (ACP) in the area of the OSC’s responsibility. The NCP states that the development of ACPs should be accomplished in cooperation with the RRT, and designated local and state representatives, as appropriate. In both contingency planning and spill response, the OSC is responsible for coordinating, directing, and reviewing the work of other agencies, Area Committees, RPs, and contractors to ensure compliance with the NCP and other plans applicable to the response.
