ACCIDENTAL RELEASE PREVENTION PROGRAM 
EXECUTIVE SUMMARY 
 
The McGregor Company 
Walla Walla Retail Facility 
Walla Walla, Washington  
 
 
1.    Facility Accidental Release Policy  
 
The owners, management, and employees of The McGregor Company along with the crew of the Walla walla facility located at Route 4 Walla Walla, Washington 99362 are committed to the prevention of any accidental release of  anhydrous ammonia.  If an accidental release should occur, the McGregor Company and the Walla Walla retail facility are prepared to work with the local fire department, or any other authorities to mitigate any release and minimize the impact of the release to people and the environment.  A detailed emergency response plan has been developed and will be implemented in the event of an accidental release. 
 
2.    Facility Information 
 
o    The primary activity at the facility is the storage, and handling of anhydrous ammonia. 
 
o    Anhydrous ammonia is received, stored, and distributed as an agricultural grade f 
ertilizer to local farmers. 
 
o    Anhydrous ammonia is received by truck and stored in one above ground tank(s).  The maximum amount of anhydrous ammonia handled is 130,000 lbs. 
 
3.    The Worst-Case Release Scenario and Alternative Release Scenario 
 
a.    Anhydrous Ammonia Worst-Case and Alternative Release Scenarios    
The worst-case release scenario involves the failure of the largest storage tank when filled to 85% capacity as limited by regulations. The scenario at this facility would release 130,000 pounds of anhydrous ammonia. The distance to the endpoint (the point of dispersion to 200ppm) is 1.12 miles. This figure comes from TFI's DEGADIS model. 
 
The alternative release scenario, is based on the most likely potential incident that might occur at this facility. We used the scenario that a 2" transfer hose would break and release 11,908 pounds of anhydrous ammonia for two minutes.  The distance to the endpoint (point of dispersion to 200 ppm) is 0.56 miles. This figure comes from TFI's  
DEGADIS model. 
 
4.  Accidental Release Prevention Program
