EROs To Go was developed using the CSEPP Exercise Policy and Guidance “Blue Book” (December 2012) to provide program guidance and supporting information for implementation of the CSEPP exercise program. The app provides CSEPP exercise evaluators with the Blue Book's “CSEPP Emergency Response Outcomes and Exercise Evaluation Guides” in a mobile format. The CSEPP exercise evaluation methodology is organized around a standard set of eight Emergency Response Outcomes (EROs). Exercise Evaluation Guides (EEGs) have been developed for each ERO and are available in the application.
