SANJ O A Q U I N Environmental Health Department COUNTY— (b)The stationary source and regulated substances handled: This facility utilizes anhydrous ammonia as a heat transfer fluid in the plant refrigeration system.The system is a single-stage, multi-suction,economized mechanical refrigeration system that utilizes recirculated liquid feed to evaporator coils. Cooling is required for the 10°F Shipping Dock and for the-20°F freezer.The system charge is approximately 13,500 lbs. One high-temperature screw compressor provides suction and compression for the high temperature cooling,while two low-temperature screw compressors serve the low-temperature cooling requirements.A swing screw compressor can back-up either the high-temperature or low-temperature requirements as needed. The heat of compression in the high-pressure compressor discharge is removed in the evaporative condenser.The condenser drains high-pressure liquid to the thermosyphon/high-pressure receiver for screw compressor cooling and Recirculator package liquid ammonia as required. Liquid from the high-temperature Recirculator(HTR)and the low-temperature Recirculator(LTR)is pumped to the evaporators as needed for cooling at the dock and in the freezer, respectively. (c)The general accidental release prevention program and chemical-specific prevention steps: The release prevention elements included in the CalARP Program Manual provide the critical elements for preventing accidental releases. Anhydrous ammonia is present in the refrigeration system above the threshold quantity of 10,000 lbs. and is, therefore, subject to the federal EPA RMP requirements and the OSHA PSM Standard. The CalARP Program 3 release prevention steps have been implemented to satisfy all federal and state requirements for the anhydrous ammonia refrigeration system. (d)The five-year accident history: There have been no accidental releases of ammonia at the Dreyer's Grand Ice Cream Manteca facility in the past five years that are subject to the CalARP or EPA Accidental Release Prevention Program reporting requirements. (e)The emergency response program: Dreyer's Grand Ice Cream maintains an Emergency Action Plan for responding to actual or potential ammonia releases. The emergency response measures primarily include the safe evacuation of all personnel and notification to outside emergency responders. Incidental releases that do not pose an imminent safety hazard may be abated by contractor employees who are trained to provide such a response, are wearing the appropriate personal protective equipment (PPE), and are authorized by Nestle DSD to perform such activities. 12 of 22 Doc ID:6a6ea4fac281501cd30efa4128b75fd8a1870d1a
