Beaver Creek, Minnesota
1. Accidental Release Prevention and Emergency Response Policies
We at Hills-Beaver Creek Co-op Farm Service in Beaver Creek 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 efforts with the local fire
department, 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 a 18,000-gallon tank at our facility in Beaver Creek (Figure 1, ammonia). The
maximum amount stored is 15,300 gallons (78,734 pounds) at the maximum fill capacity of 85 %.
We also have propane stored in a 18,000-gallon tank located at our facility in Beaver Creek (Figure
1, propane). The maximum amount stored is 15,300 gallons (64,612 pounds) at the maximum fill
capacity of 85%.
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 ammonia and propane facility. The following details these scenarios.
The worst case release scenario involves a catastrophic release of the entire contents of th
anhydrous ammonia storage tank (78,734 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 350.
The alternative release scenario involves a release from an anhydrous ammonia product line. The
scenario involves the release of 11,993.74 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 the
facility is 100.
The worst case release scenario involves a catastrophic release of the entire contents of the propane
storage tank (64,612 pounds) in gaseous form over a 10-minute period. At Class F atmospheric
stability and 1.5 m/s wind speed, the maxim
um distance to an endpoint of 1 psi overpressure is 0.32
miles (Figure 2). This amount of overpressure can cause partial demolition of houses and can result
in serious injury to people within this distance. The estimated population within a 0.32-mile radius
of this facility is 100.
The alternative release scenario involves a 30-minute release of propane from a product line that
contacts an ignition source and detonates, resulting in a vapor cloud explosion. Under neutral
weather conditions, the maximum distance to an endpoint of 1 psi overpressure is 0.14 mile (Figure
3). The estimated population within a 0.14-mile radius of this facility is 50.
