Risk Management Plan - EXECUTIVE SUMMARY 
 
l.  The Facility Policy 
 
The owners, management, and employees of Essex Elevator Inc. committed to the prevention of any accidental releases of anhydrous ammonia.  If an accidental release should occur, the facility is prepared to work with the local fire company, or other authorities, to mitigate any release and minimize the impact of the release to people and the environment. 
 
2.  Facility information. 
The primary activity at the facility is the storage and blending of fertilizers for sale to farmers.  Anhydrous ammonia is received, stored, and distributed for both direct application and for blending  into mixed-grade fertilizers for crop production nutrients. 
 
The maximum quantity stored should be 50,000 pounds in our one 12,000 gallon storage tank.  The maximum quantity handled would be the unloading of a semi tanker holding 36,000 pounds. 
 
 
3.  The worst-case release scenario and the alternative release scenario. 
 
a.  The worst-case relase scenario would be the release of the total contents of a storage tank (or tank car) released as a gas over 10 minutes.  The maximum quantity released  would be 36,000 pounds, which represents the volume of the largest storage tank at 85 percent capacity as liumited by design standards.  The distance to the endpoint (point of dispersion to 200 ppm) is 2.3 miles. 
 
b.  The alternative release scenario based on the five-year accident history (or the most likely potential incident) is a release from a break in a transfer hose.  The distance to the endpoint (point of dispersion to 200 ppm is 1.1 miles. 
 
4.  The accident release prevention program. 
 
The facility has implemented the provisions of "Safety Requirements for the Storage and Handling of Anhydrous Ammonia, K-61.1, published by the American National Standards Institute, Inc., and the standards of the U.S. Occupational Safety and Hea 
lth Administration (OSHA), 29 CFR 1910.111, "Storage and handling of anhydrous ammonia." 
 
5.  The Five-year Accident History (either a.or b.) 
 
a.  There have been no accidental releases of anhydrous ammonia in the past five years that:  have caused any deaths, injuries, or significant property damage at the facility, nor 
 
to our knowledge, have resulted in offsite deaths, injuries, evacuations, sheltering in place, property damage,
