From the Executive Summary: "On August 20, 2003, the Federal Emergency Management Agency (FEMA), Region IV, conducted a partial participation plume pathway emergency planning zone (EPZ) exercise for the Hatch Nuclear Plant. The purpose of this exercise was to assess the level of State and local preparedness in responding to a radiological incident at a nuclear power plant. The exercise was held in accordance with FEMA's policies and guidance concerning the exercise of State and local radiological emergency response plans (RERP) and procedures. The previous exercise at this site was conducted on March 14, 2001. [...] The State and local organizations demonstrated knowledge of their emergency response plans and procedures and appropriately implemented them. No Deficiencies were identified during this exercise. However there were two Areas Requiring Corrective Action (ARCAs) identified. The first ARCA was identified during the second media briefing when conflicting information was announced concerning the initial protective action decision. This ARCA was corrected during the third media briefing when correct information was provided. The second ARCA, concerning the monitoring of emergency workers and equipment in Jeff Davis County, was identified during the out-of-sequence demonstration for this exercise and was also corrected on the spot. No outstanding issues remain."
