                      Executive Summary 
              Morrow County Grain Growers, Inc. 
                         Ione, Oregon 
 1. Accidental Release Prevention and Emergency Response Policies 
We at Morrow County Grain Growers, Inc. in Ione 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 Ione Fire Department, which p 
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 Ione (Figure 1).  The maximum amount 
stored is 15,300 gallons (78,733.8 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 
anhydrous ammonia storage tank (78,733.8 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 
ius of this facility is 400. 
The alternative release scenario involves a release from an anhydrous ammonia product line.  The 
scenario involves the release of 7,616.42 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 40. 
 4. General Accidental Release Prevention Program

requirements as set forth in 40 CFR part 68.  The following sections briefly describe the elements
