This United States Coast Guard Commandant Instruction Manual, U.S. Coast Guard Emergency Management Manual Volume IV: Incident Management and Crisis Response COMDTINST M3010.24A October 2020, provides guidance on incident management and crisis response. The USCG's incident response roles and responsibilities continue to evolve, especially following events such as Hurricanes Katrina and Rita, the Haiti earthquakes, Deepwater Horizon oil spill, Superstorm Sandy, the 2017 Atlantic Hurricane Season (Harvey, Irma, and Maria) and COVID-19. The concept of preparedness has also broadened in scope through the establishment of Presidential Policy Directive-8 (PPD-8) and the five National Frameworks within the National Preparedness System. This Manual recognizes the evolution of these concepts through an explanation of the Coast Guard's incident management responsibilities. This Manual builds on doctrine to define further Coast Guard Policy with respect to incident management activities.
