 1. Accidental Release Prevention and Emergency Response Policies 
We at Farmers Union Oil Company of New Rockford/Sheyenne in New Rockford are strongly 
committed to employee, public, and environmental safety.  This commitment is an inherent part of 
our comprehensive accidental release prevention program that covers areas such as design, 
installation, operating procedures, maintenance, and employee training associated with the processes 
at our facility.  It is our policy to implement appropriate controls to prevent possible releases of 
regulated substances.  If such a release does occur, our trained emergency response personnel are 
at hand to control and mitigate the effects of the release.  We also coordinate our response effor 
with the Eddy County LEPC, which provides additional emergency response expertise. 
 2. Stationary Source and Regulated Substances Handled 
Our facility's primary activities include support services for crop production.  We have anhydrous 
ammonia stored in an 18,000-gallon tank at our facility in New Rockford (Figure 1).  The maximum 
amount stored is 15,480 gallons (79,660.08 pounds) at the maximum fill capacity of 86%. 
 3. Worst Case Release and Alternative Release Scenarios 
We utilized RMP PRO for the worst case and alternate case scenarios of the required offsite 
consequence analysis for our facility.  The following details these scenarios. 
The worst case release scenario involves a catastrophic release of the entire contents of the 
anhydrous ammonia storage tank (79,660.08 pounds) in gaseous form over a 10-minute period.  At 
Class F atmospheric stability, 1.5 m/s wind speed, and urban topography, the maximum distance to 
a toxic endpoint of 0.14 mg/L is 4.2 miles (Figure 2).   
The estimated population within a 4.2-mile 
radius of this facility is 1,900. 
The alternative release scenario involves a release from an anhydrous ammonia product line.  The 
scenario involves the release of 7837.38 pounds of ammonia in a gaseous form over a period of 30 
minutes.  Under neutral weather conditions, the maximum distance to the toxic endpoint of 0.14 
mg/L of ammonia is 0.31 mile (Figure 3).  The estimated population within a 0.31-mile radius of this 
facility is 15.
