On September 15th 2020, the Lake County Emergency Management Agency, along with partners at Ashtabula County, Geauga County, the State of Ohio and the Perry Nuclear Power Plant (PNPP), participated in the Federal Emergency Management Agency (FEMA) evaluated Radiological Emergency Preparedness Exercise (REPEX) to ensure off-site response organization readiness in the event of an emergency at the PNPP. This type of exercise is conducted and evaluated on a biennial basis and would normally involve a minimum of 200-300 players from public safety, volunteer organizations, county departments, PNPP staff and others. Due to COVID-19, the 2020 exercise had to be completed with fundamental changes in how the exercises are conducted and evaluated in order to adhere to public health and safety guidelines.
