Campbell County anchored by Gillette is the energy capital of Wyoming and one of the largest coal-producing regions in the world. The Powder River Basin in the county produces more coal than any other region in the United States. The massive coal and natural gas extraction industry creates major industrial emergency planning requirements. Extreme winter storms can paralyze the county. The remote location and industrial scale of operations create unique emergency response challenges.
