ACCIDENTAL RELEASE PREVENTION/EMERGENCY RESPONSE AT ROCKWELL AG CENTER, EMERY (MASON CITY), IOWA. This facility complies with ANSI Standard K-61.1-1995 requirements for Anhydrous Ammonia storage. It is our policy to adhere to all applicable Federal, State, and local regulations. If an emergency were to occur, it is our policy to immediately notify the Mason City Fire Department (via a 911 call) and request that it respond to the emergency. Incidental to the notification to the fire department, a call to the North Central regional Emergency Planning District will be made. While we have planned for an emergency, it is acknowledged that a real emergency will be unexpected and may very well be much different and cannot be ensured to duplicate what may have be planned. In reality, the situation that develops may not happen in the manner in which it has been planned. In that event, what may have been planned will serve only as a guideline to follow. The Emergency Action Plan for this faci lity describes certain procedures that are intended to minimize the hazards associated with human health and the environment from fires, explosions, the sudden and unexpected release of chemicals (i.e., Anhydrous Ammonia), tornadoes, bomb threats or other accidents or acts of God which might occur on our premises. The primary emergency coordinator for the Emery (Mason City), Iowa location is Ken Campbell, agronomy manager. His work and 24-hour emergency response telephone numbers are provided in the Registration Section of this document. In addition, the following individuals (with associated work and 24-hour emergency response telephone numbers) are to be contacted in order: Ken Campbell, agronomy manager WORK: (515) 423-6963 24-Hour: (515) 756-3862 Home: (515) 749-2402 Rick Demaray, Dougherty location manager WORK: (515) 794-3434 24-hour: (515) 756-3862 Home: (515) 756-3862 Paul Peters, assistant WORK: (515) 822-3205 24-hour: (515) 756-3862 Home: (515) 357-5331 DESCRIPTION OF THE ANHYDROUS AMMONIA STORAGE/DISTRIBUTION PLANT AND THE REGULATED SUBSTANCE HANDLED AT ROCKWELL AG CENTER, EMERY (MASON CITY), IOWA: This facility is a bulk anhydrous ammonia storage and distribution plant. The anhydrous ammonia that is stored at this facility is distributed to agricultural crop producers in the surrounding area who utilize the anhydrous ammonia for crop nutrient purposes. The system consists of two (2) 30,000-gallon storage tanks with associated piping, valves, liquid pump(s), and other miscellaneous equipment. The anhydrous ammonia plant is only operated on a seasonal basis (Spring and Fal l). Full-time equivalent employee numbers were computed on that basis. At a maximum, the plant operates a total of three months (1/4 of the year). The FTEs for this company location is two (2). THE WORST-CASE AND ALTERNATIVE RELEASE SCENARIOS: The worst-case scenario is the failure of the one (1) 30,000-gallon storage tank when filled to the greatest amount allowed (85% of capacity), resulting in the release of the total volume in a gaseous (hazardous ammonia vapor cloud) form. According to EPA's RMP*Comp Program (Version 1.06), the distance to the endpoint is 4.4 miles. The alternative release scenario involves the transport delivery vehicle pulling away from the intake lines into the storage plant without disconnecting the transfer hoses. The resulting release, according to EPA's RMP*Comp Program has a distance to endpoint of 0.1 miles. Since this facility is located in relatively close proximity to the Cities of Mason City and Clear Lake and the unincorporated communities of Em ery and Central Heights, provisions have been designed to notify all affected persons. An evacuation plan is in place. GENERAL ACCIDENTAL RELEASE PREVENTION PROGRAM AND CHEMICAL-SPECIFIC PREVENTION STEPS: This facility complies with EPA's accident prevention rule and all applicable State and local codes and regulations. The anhydrous ammonia system is designed, installed, and maintained in accordance with ANSI Standard K-61.1-1995 and State law. In addition the company has specific operating procedures in place intended to minimize the potential for an accidental (and potentially catastrophic) release of anhydrous ammonia. Finally, Rockwell AG Center has extended to the Mason City Fire Department the opportunity to visit our anhydrous ammonia plant, to participate in mock emergency simulation training, and to avail themselves of specific anhydrous ammonia health hazard information and training provided by the company. FIVE-YEAR ACCIDENT HISTORY: Rockwell AG Center, Emery (Mason C ity), Iowa has never had an accident involving anhydrous ammonia that caused death, injuries, property or environmental damage, evacuations or shelterings in place. THE EMERGENCY RESPONSE PROGRAM: In the event of an emergency involving our anhydrous ammonia system, it is the policy of Rockwell AG Center to immediately notify the Mason City Fire Department and the North Central Regional Emergency Planning District to request that they respond to the emergency. In the unlikely event that the Mason City Fire Department is unable to adequately respond to an emergency at our Emery location, the Fire Department with whom Mason City has a reciprocal agreement will be summoned. We have discussed this policy with the fire department and North Central regional Emergency Planning District. Members of the fire department and the LEPC have inspected our anhydrous ammonia plant. In addition, copies of photographs taken of our plant have been provided (for reference) to both entities. PLANNED C HANGES TO IMPROVE SAFETY: None. |
