Accidental release prevention and emergency response policies ConAgra Poultry Company - Athens is committed to both the safety of our employees and that of the surrounding public, including both human health and the environment. Safety is ensured through careful prevention measures and emergency planning. The intent of our Prevention Program is the minimization of all risks that could possibly lead to an accidental release. This program focuses primarily on the mechanical integrity of the process equipment and the training of its operators. The Emergency Response Plan focuses on minimizing the potential impacts of an accidental release. This is done by coordinating emergency actions with the Athens Fire Department and ensuring that employees are trained on the proper response to an emergency situation. 2. The stationary source and regulated substances handled 7 ConAgra Poultry Company - Athens is a poultry processing plant. 7 The regulated substance han dled at this plant is ammonia. Ammonia is used as a refrigerant in the plant cooler and freezer system. 7 The maximum quantity of ammonia stored at this facility is 20,000 pounds. 3. The worst-case release scenario and the alternative release scenario, including administrative controls and mitigation measures to limit the distances for each reported scenario 7 Worst-Case Scenario: Failure of the high pressure receiver outside of the north engine rooms when filled to the greatest amount allowed would release 5,750 pounds of ammonia. Company policy limits the maximum filling capacity of this vessel to 85%. It is assumed that the entire contents are released as vapor over a ten minute time span and are subjected to a wind speed of 1.5 m/s with a stability class of F. The distance to the toxic endpoint for the worst-case scenario is 0.93 miles. 7 Alternative Scenario: The lifting of a pressure relief valve on the ammonia storage vessel for the new engine room. Relief valves allow th e escape of ammonia at a total flow rate of 115 lbs/min. Weather conditions are assumed to be average values of 3 m/s wind speed and stability class D. The valves are assumed to be open 75% of the time during the release as the pressure builds and is relieved. The distance to this endpoint is 440 feet and extends beyond the facility boundary. 4. The general accidental release prevention program and the specific prevention steps ConAgra Poultry Company believes that the best way to prevent an accidental release is by being proactive in its approach to safety.
