                      Executive Summary 
               FREMAR Farmers Cooperative, Inc. 
                     Marion, South Dakota 
 1. Accidental Release Prevention and Emergency Response Policies 
We at FREMAR Farmers Cooperative, Inc. in Marion 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 Marion Fire Department,  
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 12,000- and two 11,000-gallon tanks at our facility in Marion (Figure 1).  The 
maximum amount stored is 28,900 gallons (148,719.4 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 facility.  The following details these scenarios. 
The worst case release scenario involves a catastrophic release of the entire contents of the largest 
anhydrous ammonia storage tank (52,489.2 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 3.4 miles (Figure 2).  The estimated 
population within a 3.4-mile 
radius of this facility is 950. 
The alternative release scenario involves a release from an anhydrous ammonia product line.  The 
scenario involves the release of 6,854.78 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 0.19 mile (Figure 3).  The estimated population within a 0.19-mile radius of the 
facility is zero. 
 4. General Accidental Release Prevention Program 
Our facility has taken all the necessary steps to comply with the EPA's accidental release prevention 
requirements as set forth in 40 CFR part 68.  The following sections briefly describe the elements
