Who are we?Origins of NOAA “HAZMAT” Program…
• 1976 Argo Merchant oil spill, Nantucket, MA(Spilled Oil Research Team)
• 1975 Outer Continental Shelf Environmental Assessment Program (OCSEAP)
NOAA’s Office of Response and Restoration (OR&R)“We have been part of the science of oil and chemical spills for a very
long time.”
Five Emergency Response Questions?
• What was spilled? (Oil Chemistry)
• Where is it going? (Oil Forecasts)
• What’s at risk? (RAR/ESI)
• How will it hurt? (Potential Impacts)
• What can be done to mitigate the hurt? (Alternative Response Technologies)
How did it hurt? (Natural Resource Damage Assessment or NRDA Process)
In-Situ Burning and Dispersants Use at the Two Spills
– In-Situ Burn
• Exxon Valdez - Test Burn Only• Deepwater Horizon – >400 Individual In-Situ
Burns– Dispersants
• Exxon Valdez – Test Application Only• Deepwater Horizon – Roughly 400 Individual
Aerial Sorties• Deepwater Horizon – Subsurface Application
of Dispersants (something new)
Sub-Surface (Sea Floor) Dispersant Application
– Operational Issues and Authorization– Would it even work?
(mixing and resonance times)– Dispersed Plume Transport (Where would it go?)– Receptors - Resources at Risk
(What’s at risk and how will it hurt?)– Overall Spill Trade-offs (What would hurt less?)– Monitoring for Effectiveness (Efficacy) and Effects
– Adaptive Management Strategy

Final Comment
“…one objective of science in oil spill response is to learn from past spills and apply
this knowledge to the next spill.”
