Illinois Clusters

CHUG Clusters are groups of member facilities located within the same geographic region. The facilities located within a cluster work collaboratively to remain prepared for emergencies. Based on the scope of the disaster, a single cluster can be notified for a smaller event, and additional clusters can be alerted if the event requires a larger response. Please see below for a map of the clusters in Illinois as well as a listing of counties within each cluster.
