The Indiana Department of Homeland Security’s Radiological Emergency Preparedness Program (REPP) protects the health and safety of Indiana citizens living around commercial nuclear power plants by informing and educating the public about radiological emergency preparedness and by coordinating with local, state, and federal government agencies to prepare Indiana for an integrated response.


In the event of a release of radiological materials from a nuclear power plant, the primary concern for Indiana and its residents is the Ingestion Pathway Planning Zone. This emergency planning zone is the geographical area within fifty-miles of one of four nuclear power plants located in Michigan and Illinois near Indiana’s borders.  The Indiana REPP is designed to provide protection to the public from the consumption of food and water potentially contaminated by radioactive material from a radioactive release at one of these locations.   

The REPP is specifically responsible for “offsite” activities, that is, State, Tribal, and local government emergency planning and preparedness activities that take place beyond the nuclear power plant boundaries.  The program is designed to enhance the coordination with other state agencies so that the agricultural community within the potential Ingestion Exposure Pathway would be adequately informed and educated. The agricultural community will be clearly advised on necessary protective actions in order to reduce the risk of radiological injury or contamination of farm livestock, livestock feeds, farm products, and water supplies. 

Future Plan for the REP Program

The goal is for the Indiana Ingestion Pathway Plan to be updated and reviewed starting the Fall of 2013. Much progress was made during the October, 2012 Ingestion Pathway Exercise. Both strengths and weaknesses were identified and will be addressed during the revision of the Plan. Federal Emergency Management Agency (FEMA) has published a June, 2013 REP Program Manual that will be used as a guidance for the updated Indiana Ingestion Pathway Plan. Additionally, the Environmental Protection Agency (EPA) has published a new version of the Protective Action Guidance that needs to be incorporate into the Indiana Plan.

Annual training will be a primary focus of the Indiana REP Program. This training will focus on field sampling and overall nuclear power education. Training will be offered to keep all stakeholders involved with the REP Program. Additionally, setting up Tabletop Exercises to practice knowledge acquired will be offered. Those individuals interested in training should contact Mary Stiker at or (317) 464-7394
