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 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.

DESCRIPTION OF THE ANHYDROUS AMMONIA STORAGE/DISTRIBUTION PLANT AND THE REGULATED SUBSTANCE HANDLED AT PRAIRIE LAND COOPERATIV, GARDEN 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 one  (1)  12,000-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 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 one (1). 
 
THE WORST-CASE AND ALTERNATIVE RELEASE SCENARIO: 
 
The worst-case s 
cenario is the failure of the one (1) 12,000-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 2.6 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 Town of Garden City, provisions have been designed to notify all affected persons in the Town of Garden City. 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, Prairie Land Cooperative has extended to the Garden City 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: 
 
Prairie Land Cooperative, Garden City, 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 ammoni 
a system, it is the policy of Prairie Land Cooperative to immediately notify the Garden City Volunteer Fire Department and the Hardin County, Iowa LEPC to request that they respond to the emergency. In the unlikely event that the Garden City Fire Department is unable to adequately respond to an emergency at our Garden City location, the Volunteer Fire Department with whom Prairie Land Cooperative has a reciprocal agreement will be summoned.  We have discussed this policy with the fire department and Hardin County LEPC. 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.
