The Agency for Toxic Substances and Disease Registry (ATSDR) and Center for Disease Control and Prevention’s (CDC) National Center for Environmental Health (NCEH) have subject matter experts that respond to public health emergencies — whether natural disasters or chemical releases to the environment. NCEH/ATSDR may activate a response for environmental emergencies at a program, center, or agency level. In preparation for an environmental emergency response, we have different tools to characterize emergencies, identify target populations of concern, assess risk, evaluate health response capacity, coordinate response, and communicate actions to protect health. In this presentation, you will learn best practices from responding to these emergencies developed resources that are available and can be easily adapted for tribal use to prepare, respond, or recover from environmental emergencies.
