Thousands of incidents occur each year in which oil or chemicals are released into the environment as a result of accidents or natural disasters. Spills into our coastal waters, whether accidental or intentional, can harm people and the environment and cause substantial disruption of marine transportation with potential widespread economic impacts.

The Emergency Response Division (ERD) of NOAA's Office of Response and Restoration (OR&R) provides scientific expertise to support an incident response. Under the National Contingency Plan, NOAA has responsibility for providing scientific support to the Federal On-Scene Coordinator (FOSC) for oil and hazardous material spills. To support this mandate, ERD provides 24-hour, 7 day a week response to spill events. Find out more about ERD's work with oil and chemical spills.

When spills occur, NOAA Scientific Support Coordinators (SSCs) coordinate scientific information and provide critical information to the FOSC. A multidisciplinary team of ERD scientists, including oceanographers, modelers, biologists, chemists, and geologists, are based in Seattle and support the SSCs during spill events, as well as for drills, exercises, and contingency planning. SSCs are strategically located around the country, often within U.S. Coast Guard (USCG) offices, effectively providing local services to a range of users in public and private sectors. ERD services include:

• Supporting emergency response activities
• Assisting in the development of contingency plans
• Developing tools for local decision makers
• Providing training

ERD facilitates spill prevention, preparedness, and response at national and local levels, and provides expertise on such issues as dispersant use, response countermeasures, and alternative response technologies.

ERD's scope encompasses the entire U.S. coastline, including the Great Lakes, Alaska, Hawaii, and U.S. territories. In the last twenty-five years, ERD has responded to virtually every major marine spill in the U.S. In addition, ERD's expertise is frequently sought internationally. While oil and chemical spills are the major focus, ERD also provides support for incidents such as downed aircraft, search and rescue, and tracking floating objects.

The Emergency Response Division typically responds to 150-200 incidents annually. Descriptions of some recent responses by ERD are available in our Significant Incidents section. News, photos, and other information about current and historical spill incidents is available at OR&R's IncidentNews site.

ERD develops tools, guidelines, and small, field-oriented job aids to assist preparedness for response communities. In addition, NOAA provides standard techniques for observing oil, assessing shoreline impact, and evaluating and selecting cleanup technologies that have been widely accepted by response agencies.

Some of ERD's more widely distributed products:

• Environmental Sensitivity Index (ESI) maps and data are used to identify vulnerable resources and habitats in advance of emergencies so that appropriate response actions can be planned. ERD works with local experts to develop or update ESI maps throughout the country. The maps are available for download in a variety of formats.
• The GNOME suite of oil spill response tools estimates the fate and transport of pollutants (such as oil) spilled in water.
• The CAMEO® software suite helps emergency planners and responders deal with chemical incidents. The suite includes a hazard modeling application (ALOHA®), a database of hazardous chemical datasheets with response recommendations and reactivity prediction tool (CAMEO Chemicals), a mapping program (MARPLOT®), and a data management program (CAMEOfm). The suite is developed jointly with the Environmental Protection Agency.

Each year, ERD provides training to approximately a thousand individuals in industry and government on the scientific aspects of oil and chemical spill response. The goal of ERD training is to transfer scientific expertise and experience to the broadest possible audience. Successful training promotes more efficient planning and spill response.
