ACCIDENTAL RELEASE PREVENTION/EMERGENCY RESPONSE AT COOPERATIVE ELEVATOR ASSOCIATION, OCHEYDAN, 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 Ocheyedan Volunteer 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 Osceola County, Iowa LEPC (Region 3 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 Emergenc y Action Plan for this facility 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 Ocheyedan, Iowa location is Steve Glade, agronomy sales and operations 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: Steve Glade, agronomy sales and operations manager WORK: (712) 758-3621 24-Hour: (712) 758-3241 Dennis Maas, general manager WORK: (712) 758-3621 24-hour: (712) 758-3133 Steve Loeschen, agronomy operations WORK: (712) 758-3621 24-hour: (712) 758-3166 DESCRIPTION OF THE ANHYDROUS AMMONIA STORAGE/DISTRIBUTION PLANT AND THE REGULATED SUBSTANCE HANDLED AT COOPERATIVE ELEVATOR ASSOCIATION, OCHEYEDAN, 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 one (1) 11,800-gallon, one (1) 12,000-gallon, one (1) 26,000-gallon and one (1) 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 Fall). Full-time equivalent employee number s 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 three (3). 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. There is one (1) 10,000 gallon LP Gas storage tank located approximately 198 feet southwest of the one (1) 26,000 gallon NH3 tank, one (1) 30,000 gallon LP Gas storage tank located a pproximately 146 feet south of the one (1) 30,000 gallon NH3 tank, and one (1) 30,000 gallon LP Gas storage tank located approximately 1050 feet east of the one (1) 30,000 gallon NH3 storage tank. It is believed that it is unlikely that any of the three(3) LP Gas storage vessels would be likely to be impinged upon in the event that any unfortuitous event were to occur at theanhydrous ammonia plant reported in this plan. However, for emergency planning preparedness these vessels are included in the executive summary section of this Plan. Since this facility is located in relatively close proximity to the Town of Ocheyedan, 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 i n 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, Cooperative Elevator Association has extended to the Ocheyedan Volunteer 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: Cooperative Elevator Association, Ocheyedan, Iowa has not experienced any accidental release involving anhydrous ammonia in the last five years 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 Cooperative Elevator Association t o immediately notify the Ocheyedan Volunteer Fire Department and the Osceola County, Iowa (Region 3 Emergency Planning District) LEPC to request that they respond to the emergency. In the unlikely event that the Ocheyedan Fire Department is unable to adequately respond to an emergency at our Ocheyedan location, the Volunteer Fire Department with whom Ocheyedan has a reciprocal agreement will be summoned. We have discussed this policy with the fire department and Osceola County LEPC (Region 3 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. As indicated previously in the Worst-case and alternative release section of this summary, there is one (1) 10,000-gallon and two (2) 30,000-gallon propane storage tanks situated across the street from the anhydrous plant. A worst-case scenario for a propane release resulting in a vapor cloud explosion has been computed utilizing EPA's RMP*Comp (1.06 Version). The distance to endpoint for either size tank is 0.4 miles. At the current time propane has been exempted from Risk Management Planning. However, we have considered the impact of a catastrophic release from either propane facility on our anhydrous ammonia plant. PLANNED CHANGES TO IMPROVE SAFETY: None. |
