This Exercise Plan (EXPLAN) is designed to aid exercise planners in the design and implementation of an effective exercise. An EXPLAN also enables exercise participants to understand their roles and responsibilities in exercise planning, execution, and evaluation. This EXPLAN was produced by the Colorado Department of Public Health and Environment (CDPHE) Emergency Preparedness and Response Division (EPRD) with input, advice, and assistance from public health regional staff in all nine of the Colorado All-Hazards Emergency Management Regions.
