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.
