Interagency Modeling Atmospheric Assessment Center local jurisdiction : IMAAC operations framework

Abstract

The Interagency Modeling Atmospheric Assessment Center (IMAAC) is a Department of Homeland Security (DHS) interagency working group responsible to create atmospheric air plume dispersion model predictions for designated emergencies. When 'activated' IMAAC is comprised of representatives from eight federal agencies with the National Atmospheric Release Advisory Center (NARAC) serving as the interim host. The Center concept was designed to eliminate contradictory plume predictions during weapons of mass of destruction (WMD) and hazardous materials incidents. IMAAC plume predictions represent the federal position during such emergencies. IMAAC resources are also available to assist local jurisdictions during incidents requiring 'federal coordination' as cited by the DHS National Response Framework. An operations framework model has been devised in this thesis to address ongoing plume modeling issues between IMAAC and first responders in need of fast and accurate plume predictions during accidental or intentional spills, releases, or discharges of WMD or hazardous materials into the environment. The proposed operations framework model is designed to address related obstacles facing first responders including IMAAC Web-based and stand-alone models accessibility, incident "reach back" support, coordinated procedures, training, exercises, and funding.
