From the Executive Summary: "On May 12, 2009, a Radiological Emergency Preparedness Partial Participation Plume Exposure Pathway Exercise was conducted for the 10-mile Emergency Planning Zone around the Davis-Besse Nuclear Power Station (DBNPS) by the U.S. Department of Homeland Security (DHS)/Federal Emergency Management Agency (FEMA). The purpose of this exercise was to assess the-level of State and local preparedness in responding to an emergency. This exercise was held in accordance with DHS/FEMA policies and guidance concerning the exercise of State and local radiological emergency response plans (RERPs) and procedures. [...] No Deficiencies or Areas Requiring Corrective Actions (ARCA) were identified for the State of Ohio or for Ottawa County. There was one ARCA identified during a previous exercise (May 15, 2007) for Ottawa County. The ARCA issued for Ottawa County was issued under 1.e.1 - Equipment, maps, displays, dosimetry, potassium iodide (KI), and other supplies are sufficient to support emergency operations, where the hospital was unaware of the need for the monitoring instrumentation to be calibrated. This ARCA was successfully redemonstrated. There was one ARCA identified for Lucas County during the May 12, 2009, exercise. The ARCA was issued under 6.b.1 - The facility/Offsite Response Organization (ORO) has adequate procedures and resources for the accomplishment of monitoring and decontamination of emergency worker equipment, including vehicles, whereby Jerusalem Fire Department did not demonstrate knowledge of the contamination action level, which was established as 300 counts per minute (cpm) or higher above background. This ARCA was successfully redemonstrated during the exercise."
