1.Facility Policy. 
The owners, management and employees of F.J. Krob & Co. (the facility) are commited to the prevention of any accidental release of anhydrous ammonia.  If an accidental release should occur, the facility is prepare to work with the local fire department, or other authorities, to mitigate and minimize the impacts of the release to the people and the environment. 
2. Facility Information. 
The primary activity at the facility is the storage of fertilizers for sale to farmers.  Anhydrous ammonia is received, stored and distributed for direct application and for crop production nutrients.  The maximum quantity stored would be 127,500 pounds. 
3. Worst- Case Scenario and Alternate Release Scenario. 
a. The worst-case scenario would be the release of the total contents of a storage tank as a gas over a period of ten minutes.  The maximum quantity r 
eleased would be 127,500 pounds, which represents the volume of the largest tank at 85 percent capacity as limited by design standards.  The distance to the end point (point of dispersion to 200 parts per million, or ppm) is 2.4 miles. 
b. The alternate release scenario, based on the five-year accident history (or the most likely potential incident), is a release from a break in a 3-inch transfer hose followed by release of anhydrous ammonia for two minutes before an automatic or manual shut-off intervenes and stops the flow of ammonia.  The maximum quantity released would be 26,600 pounds.  The distance to the endpoint (point of dispersion to 200 ppm) is 1.6 miles.
