Heinz Frozen Food Company Ontario, Oregon Food Processing Facility EPA Risk Management Program Executive Summary 1. Accidental Release Prevention and Emergency Response Polices Heinz Frozen Food Company s (HFFC) manufacturing sites comply with applicable federal, state and local regulations. As with all HFFC manufacturing locations, this food processing facility has a formal worker safety program. All employees are informed of hazards in the workplace. Employees who work with potentially hazardous substances receive proper training in the handling of those substances. This facility has procedures in place to safely remove employees from areas in the unlikely event that a hazardous substance release were to occur, and to put in place emergency notification and response procedures. 2. Facility and Regulated Substances This Heinz Frozen Food Company food processing facility is located at 175 N.E. 6th Avenue, Ontario, Oregon. Frozen prepared foods are produced at this location. Food ingredients are received, washed, peeled, cut, blanched, fried, frozen and packaged. The regulated substance at this facility, anhydrous ammonia, is used in a closed-loop refrigeration system for product cooling and freezing. Ammonia is the most effective, energy efficient and environmentally safe chemical for keeping food at it's proper temperature. 3. Worst-Case and Alternate-Case Release Scenarios The worst-case scenario consists of the release of ammonia from the largest vessel over a period of ten minutes. The maximum quantity of ammonia in the vessel is limited to 30-percent of the total volume of 35,800 pounds via written administrative controls, resulting in a release of approximately 11,000 pounds of ammonia. There are off-site impacts under this worst-case scenari o. The alternate-case scenario consists of the release of ammonia vapor from a safety relief valve due to an overpressure condition in a vessel located in the facility s machine room. The relief valve is designed to vent ammonia to the atmosphere when its pressure rating is exceeded, preventing potential damage to other components in the refrigeration system. The scenario results in a 210- pound ammonia release over a period of 11 minutes. There are no off-site impacts under the alternate-case scenario. If an accidental release of ammonia occurs, an Incident Investigation Team is mobilized to determine the root cause of the release. The team develops corrective actions to prevent similar releases in the future. 4. General Accidental Release Prevention Program and Ammonia Specific Prevention All Heinz Frozen Food Company manufacturing locations comply with the OSHA Process Safety Management for Highly Hazardous Chemicals (PSM) standard relative to anhydrous ammonia. Therefore, this facility has programs to ensure proper operation and maintenance of the ammonia refrigeration system. Further, refrigeration system operators have been trained and are knowledgeable in the safe operation of the refrigeration system. The ammonia refrigeration system at this facility has been designed and constructed using good engineering practices and to conform to industry standards. The system includes ammonia detection devices,high- and low-level switches in pressure vessels, and safety relief valves to avert serious system overpressure. Periodic maintenance on the refrigeration system is ensured via the use of a computerized maintenance management system. Annual physical system audits are performed by an external refrigeration contractor to ensure system integrity. 5. Five Year Accident History During the past five years this facility has had no significant accidental releases of ammonia. 6. Emergency Response Program This food processing facility has proced ures in place to respond to the release of a hazardous substance. Employees are trained to evacuate their respective areas in accordance with OSHA 1910.38(a). Specific employees are designated and further trained to respond to a release in accordance with OSHA 1910.120(q). Coordination with the local fire department and LEPC is initiated during an emergency situation. |
