The Emergency Response Plan focusses on minimizing the potnential impacts of an accidental release. This is done by coordinating actions with the Suwanee Fire Department. 2. The stationary source and required substances handled -Mrs. Smith's Bakeries - Suwanee is a handling facility for baked goods. -The regulated substance handled at this plant is ammonia. Ammonioa is used as a refrigerant in the plant cooler and freezer system. -The maximum quantit y of ammonia stored at this facility is 19,000 pounds. 3. The worst-case release scenario and the alternative release scenario, include administrative controls and mitigation measures to limit the distances for each reported scenario. -Worst-Case Scenario: Failure of the high pressure receiver fo the main engine room when filled to the greatest amount allowed would release 10,500 pounds of ammonia. Compnay policy limits the maximum filling capaciy of this vessel to 50%. It is assumed that the entire contents are released as a vapor over a ten minute time span and are subjected to a wind speed of 1.5 m/s with a stabilty class of F. The distance to the toxic endpoint for the worst-case scenario is 1.2 miles. -Alternative Scenario: the lifting of a pressure release valve on the ammonia storage vessel for the new engine room. Relief valves allow the escape of ammonia at a total flow rate 180.8 lbs/min. Weather conditions are assumed to be average values of 3 m/s wind speed and stabi lity 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 530 feet and extends beyond the facility boundary. 4. The general accidental release prevention program and the specific prevention steps Mrs. Smith's Bakeries - Suwanee believes that the best way to prevent an accidental release is by being proactive in its approach to safety. This facility maintains information about the proper use of its equipment and the possible hazards. By following set operating procedures and maintenance routines, the process equipment within the facility will continue to operate in optimum condition. Additionally, the release prevention program is constantly being improved by sustained employee training and regular compliance audits. Compliance with all applicable state codes and regulations ensures the continued safety of Mrs. Smith's Bakeries. 5. Five-year accident history Mrs. Smith';s Bakeries - Suwanee facility has not experienced any accidents within the last five years that either led to a significant release of ammonia or had the potential to lead to such a release. 6. The emergency response program A well planned emergency response program can make a tremendous difference in the potential off-site impacts of an accidental release. Swift, efficient actions can minimize the damage to both human population and the natural surroundings.
